-# Zstd Go Wrapper
-
-[C Zstd Homepage](https://github.com/Cyan4973/zstd)
-
-The current headers and C files are from *v1.4.1* (Commit
-[52181f8](https://github.com/facebook/zstd/releases/tag/v1.4.1)).
-
-## Usage
-
-There are two main APIs:
-
-* simple Compress/Decompress
-* streaming API (io.Reader/io.Writer)
-
-The compress/decompress APIs mirror that of lz4, while the streaming API was
-designed to be a drop-in replacement for zlib.
-
-### Simple `Compress/Decompress`
-
-
-```go
-// Compress compresses the byte array given in src and writes it to dst.
-// If you already have a buffer allocated, you can pass it to prevent allocation
-// If not, you can pass nil as dst.
-// If the buffer is too small, it will be reallocated, resized, and returned bu the function
-// If dst is nil, this will allocate the worst case size (CompressBound(src))
-Compress(dst, src []byte) ([]byte, error)
-```
-
-```go
-// CompressLevel is the same as Compress but you can pass another compression level
-CompressLevel(dst, src []byte, level int) ([]byte, error)
-```
-
-```go
-// Decompress will decompress your payload into dst.
-// If you already have a buffer allocated, you can pass it to prevent allocation
-// If not, you can pass nil as dst (allocates a 4*src size as default).
-// If the buffer is too small, it will retry 3 times by doubling the dst size
-// After max retries, it will switch to the slower stream API to be sure to be able
-// to decompress. Currently switches if compression ratio > 4*2**3=32.
-Decompress(dst, src []byte) ([]byte, error)
-```
-
-### Stream API
-
-```go
-// NewWriter creates a new object that can optionally be initialized with
-// a precomputed dictionary. If dict is nil, compress without a dictionary.
-// The dictionary array should not be changed during the use of this object.
-// You MUST CALL Close() to write the last bytes of a zstd stream and free C objects.
-NewWriter(w io.Writer) *Writer
-NewWriterLevel(w io.Writer, level int) *Writer
-NewWriterLevelDict(w io.Writer, level int, dict []byte) *Writer
-
-// Write compresses the input data and write it to the underlying writer
-(w *Writer) Write(p []byte) (int, error)
-
-// Close flushes the buffer and frees C zstd objects
-(w *Writer) Close() error
-```
-
-```go
-// NewReader returns a new io.ReadCloser that will decompress data from the
-// underlying reader.  If a dictionary is provided to NewReaderDict, it must
-// not be modified until Close is called.  It is the caller's responsibility
-// to call Close, which frees up C objects.
-NewReader(r io.Reader) io.ReadCloser
-NewReaderDict(r io.Reader, dict []byte) io.ReadCloser
-```
-
-### Benchmarks (benchmarked with v0.5.0)
-
-The author of Zstd also wrote lz4. Zstd is intended to occupy a speed/ratio
-level similar to what zlib currently provides.  In our tests, the can always
-be made to be better than zlib by chosing an appropriate level while still
-keeping compression and decompression time faster than zlib.
-
-You can run the benchmarks against your own payloads by using the Go benchmarks tool.
-Just export your payload filepath as the `PAYLOAD` environment variable and run the benchmarks:
-
-```go
-go test -bench .
-```
-
-Compression of a 7Mb pdf zstd (this wrapper) vs [czlib](https://github.com/DataDog/czlib):
-```
-BenchmarkCompression               5     221056624 ns/op      67.34 MB/s
-BenchmarkDecompression           100      18370416 ns/op     810.32 MB/s
-
-BenchmarkFzlibCompress             2     610156603 ns/op      24.40 MB/s
-BenchmarkFzlibDecompress          20      81195246 ns/op     183.33 MB/s
-```
-
-Ratio is also better by a margin of ~20%.
-Compression speed is always better than zlib on all the payloads we tested;
-However, [czlib](https://github.com/DataDog/czlib) has optimisations that make it
-faster at decompressiong small payloads:
-
-```
-Testing with size: 11... czlib: 8.97 MB/s, zstd: 3.26 MB/s
-Testing with size: 27... czlib: 23.3 MB/s, zstd: 8.22 MB/s
-Testing with size: 62... czlib: 31.6 MB/s, zstd: 19.49 MB/s
-Testing with size: 141... czlib: 74.54 MB/s, zstd: 42.55 MB/s
-Testing with size: 323... czlib: 155.14 MB/s, zstd: 99.39 MB/s
-Testing with size: 739... czlib: 235.9 MB/s, zstd: 216.45 MB/s
-Testing with size: 1689... czlib: 116.45 MB/s, zstd: 345.64 MB/s
-Testing with size: 3858... czlib: 176.39 MB/s, zstd: 617.56 MB/s
-Testing with size: 8811... czlib: 254.11 MB/s, zstd: 824.34 MB/s
-Testing with size: 20121... czlib: 197.43 MB/s, zstd: 1339.11 MB/s
-Testing with size: 45951... czlib: 201.62 MB/s, zstd: 1951.57 MB/s
-```
-
-zstd starts to shine with payloads > 1KB
-
-### Stability - Current state: STABLE
-
-The C library seems to be pretty stable and according to the author has been tested and fuzzed.
-
-For the Go wrapper, the test cover most usual cases and we have succesfully tested it on all staging and prod data.

-Tutorial :
-----------
-The first step is to count all symbols. FSE_count() does this job very fast.
-Result will be saved into 'count', a table of unsigned int, which must be already allocated, and have 'maxSymbolValuePtr[0]+1' cells.
-'src' is a table of bytes of size 'srcSize'. All values within 'src' MUST be <= maxSymbolValuePtr[0]
-maxSymbolValuePtr[0] will be updated, with its real value (necessarily <= original value)
-FSE_count() will return the number of occurrence of the most frequent symbol.
-This can be used to know if there is a single symbol within 'src', and to quickly evaluate its compressibility.
-If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).
-
-The next step is to normalize the frequencies.
-FSE_normalizeCount() will ensure that sum of frequencies is == 2 ^'tableLog'.
-It also guarantees a minimum of 1 to any Symbol with frequency >= 1.
-You can use 'tableLog'==0 to mean "use default tableLog value".
-If you are unsure of which tableLog value to use, you can ask FSE_optimalTableLog(),
-which will provide the optimal valid tableLog given sourceSize, maxSymbolValue, and a user-defined maximum (0 means "default").
-
-The result of FSE_normalizeCount() will be saved into a table,
-called 'normalizedCounter', which is a table of signed short.
-'normalizedCounter' must be already allocated, and have at least 'maxSymbolValue+1' cells.
-The return value is tableLog if everything proceeded as expected.
-It is 0 if there is a single symbol within distribution.
-If there is an error (ex: invalid tableLog value), the function will return an ErrorCode (which can be tested using FSE_isError()).
-
-'normalizedCounter' can be saved in a compact manner to a memory area using FSE_writeNCount().
-'buffer' must be already allocated.
-For guaranteed success, buffer size must be at least FSE_headerBound().
-The result of the function is the number of bytes written into 'buffer'.
-If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError(); ex : buffer size too small).
-
-'normalizedCounter' can then be used to create the compression table 'CTable'.
-The space required by 'CTable' must be already allocated, using FSE_createCTable().
-You can then use FSE_buildCTable() to fill 'CTable'.
-If there is an error, both functions will return an ErrorCode (which can be tested using FSE_isError()).
-
-'CTable' can then be used to compress 'src', with FSE_compress_usingCTable().
-Similar to FSE_count(), the convention is that 'src' is assumed to be a table of char of size 'srcSize'
-The function returns the size of compressed data (without header), necessarily <= `dstCapacity`.
-If it returns '0', compressed data could not fit into 'dst'.
-If there is an error, the function will return an ErrorCode (which can be tested using FSE_isError()).

-Tutorial :
-----------
-(Note : these functions only decompress FSE-compressed blocks.
- If block is uncompressed, use memcpy() instead
- If block is a single repeated byte, use memset() instead )
-
-The first step is to obtain the normalized frequencies of symbols.
-This can be performed by FSE_readNCount() if it was saved using FSE_writeNCount().
-'normalizedCounter' must be already allocated, and have at least 'maxSymbolValuePtr[0]+1' cells of signed short.
-In practice, that means it's necessary to know 'maxSymbolValue' beforehand,
-or size the table to handle worst case situations (typically 256).
-FSE_readNCount() will provide 'tableLog' and 'maxSymbolValue'.
-The result of FSE_readNCount() is the number of bytes read from 'rBuffer'.
-Note that 'rBufferSize' must be at least 4 bytes, even if useful information is less than that.
-If there is an error, the function will return an error code, which can be tested using FSE_isError().
-
-The next step is to build the decompression tables 'FSE_DTable' from 'normalizedCounter'.
-This is performed by the function FSE_buildDTable().
-The space required by 'FSE_DTable' must be already allocated using FSE_createDTable().
-If there is an error, the function will return an error code, which can be tested using FSE_isError().
-
-`FSE_DTable` can then be used to decompress `cSrc`, with FSE_decompress_usingDTable().
-`cSrcSize` must be strictly correct, otherwise decompression will fail.
-FSE_decompress_usingDTable() result will tell how many bytes were regenerated (<=`dstCapacity`).
-If there is an error, the function will return an error code, which can be tested using FSE_isError(). (ex: dst buffer too small)

-These functions are inner components of FSE_compress_usingCTable().

-
-A key property to keep in mind is that encoding and decoding are done **in reverse direction**.
-So the first symbol you will encode is the last you will decode, like a LIFO stack.
-
-You will need a few variables to track your CStream. They are :
-
-FSE_CTable    ct;         // Provided by FSE_buildCTable()
-BIT_CStream_t bitStream;  // bitStream tracking structure
-FSE_CState_t  state;      // State tracking structure (can have several)

-    size_t errorCode = BIT_initCStream(&bitStream, dstBuffer, maxDstSize);
-    FSE_initCState(&state, ct);
-
-Note that BIT_initCStream() can produce an error code, so its result should be tested, using FSE_isError();
-You can then encode your input data, byte after byte.
-FSE_encodeSymbol() outputs a maximum of 'tableLog' bits at a time.
-Remember decoding will be done in reverse direction.
-    FSE_encodeByte(&bitStream, &state, symbol);
-
-At any time, you can also add any bit sequence.
-Note : maximum allowed nbBits is 25, for compatibility with 32-bits decoders
-    BIT_addBits(&bitStream, bitField, nbBits);
-
-The above methods don't commit data to memory, they just store it into local register, for speed.
-Local register size is 64-bits on 64-bits systems, 32-bits on 32-bits systems (size_t).
-Writing data to memory is a manual operation, performed by the flushBits function.
-    BIT_flushBits(&bitStream);
-
-Your last FSE encoding operation shall be to flush your last state value(s).
-    FSE_flushState(&bitStream, &state);
-
-Finally, you must close the bitStream.
-The function returns the size of CStream in bytes.
-If data couldn't fit into dstBuffer, it will return a 0 ( == not compressible)
-If there is an error, it returns an errorCode (which can be tested using FSE_isError()).

-BIT_DStream_unfinished : there is still some data left into the DStream.
-BIT_DStream_endOfBuffer : Dstream reached end of buffer. Its container may no longer be completely filled.
-BIT_DStream_completed : Dstream reached its exact end, corresponding in general to decompression completed.
-BIT_DStream_tooFar : Dstream went too far. Decompression result is corrupted.
-
-When reaching end of buffer (BIT_DStream_endOfBuffer), progress slowly, notably if you decode multiple symbols per loop,
-to properly detect the exact end of stream.
-After each decoded symbol, check if DStream is fully consumed using this simple test :
-    BIT_reloadDStream(&DStream) >= BIT_DStream_completed
-
-When it's done, verify decompression is fully completed, by checking both DStream and the relevant states.
-Checking if DStream has reached its end is performed by :
-    BIT_endOfDStream(&DStream);
-Check also the states. There might be some symbols left there, if some high probability ones (>50%) are possible.

-/*!XXH_FORCE_MEMORY_ACCESS :
- * By default, access to unaligned memory is controlled by `memcpy()`, which is safe and portable.
- * Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
- * The below switch allow to select different access method for improved performance.
- * Method 0 (default) : use `memcpy()`. Safe and portable.
- * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
- *            This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
- * Method 2 : direct access. This method doesn't depend on compiler but violate C standard.
- *            It can generate buggy code on targets which do not support unaligned memory accesses.
- *            But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
- * See http://stackoverflow.com/a/32095106/646947 for details.
- * Prefer these methods in priority order (0 > 1 > 2)

-*  Streaming compression - howto
-*
-*  A ZBUFF_CCtx object is required to track streaming operation.
-*  Use ZBUFF_createCCtx() and ZBUFF_freeCCtx() to create/release resources.
-*  ZBUFF_CCtx objects can be reused multiple times.
-*
-*  Start by initializing ZBUF_CCtx.
-*  Use ZBUFF_compressInit() to start a new compression operation.
-*  Use ZBUFF_compressInitDictionary() for a compression which requires a dictionary.
-*
-*  Use ZBUFF_compressContinue() repetitively to consume input stream.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written within *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present again remaining data.
-*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each call, so save its content if it matters or change @dst .
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's just a hint, to improve latency)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  At any moment, it's possible to flush whatever data remains within buffer, using ZBUFF_compressFlush().
-*  The nb of bytes written into `dst` will be reported into *dstCapacityPtr.
-*  Note that the function cannot output more than *dstCapacityPtr,
-*  therefore, some content might still be left into internal buffer if *dstCapacityPtr is too small.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  ZBUFF_compressEnd() instructs to finish a frame.
-*  It will perform a flush and write frame epilogue.
-*  The epilogue is required for decoders to consider a frame completed.
-*  Similar to ZBUFF_compressFlush(), it may not be able to output the entire internal buffer content if *dstCapacityPtr is too small.
-*  In which case, call again ZBUFF_compressFlush() to complete the flush.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  Hint : _recommended buffer_ sizes (not compulsory) : ZBUFF_recommendedCInSize() / ZBUFF_recommendedCOutSize()
-*  input : ZBUFF_recommendedCInSize==128 KB block size is the internal unit, use this value to reduce intermediate stages (better latency)
-*  output : ZBUFF_recommendedCOutSize==ZSTD_compressBound(128 KB) + 3 + 3 : ensures it's always possible to write/flush/end a full block. Skip some buffering.
-*  By using both, it ensures that input will be entirely consumed, and output will always contain the result, reducing intermediate buffering.

-*  Streaming compression
-*
-*  A ZBUFF_CCtx object is required to track streaming operation.
-*  Use ZBUFF_createCCtx() and ZBUFF_freeCCtx() to create/release resources.
-*  Use ZBUFF_compressInit() to start a new compression operation.
-*  ZBUFF_CCtx objects can be reused multiple times.
-*
-*  Use ZBUFF_compressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to call again the function with remaining input.
-*  The content of dst will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters or change dst .
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to improve latency)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  ZBUFF_compressFlush() can be used to instruct ZBUFF to compress and output whatever remains within its buffer.
-*  Note that it will not output more than *dstCapacityPtr.
-*  Therefore, some content might still be left into its internal buffer if dst buffer is too small.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  ZBUFF_compressEnd() instructs to finish a frame.
-*  It will perform a flush and write frame epilogue.
-*  Similar to ZBUFF_compressFlush(), it may not be able to output the entire internal buffer content if *dstCapacityPtr is too small.
-*  @return : nb of bytes still present into internal buffer (0 if it's empty)
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory)
-*  input : ZSTD_BLOCKSIZE_MAX (128 KB), internal unit size, it improves latency to use this value.
-*  output : ZSTD_compressBound(ZSTD_BLOCKSIZE_MAX) + ZSTD_blockHeaderSize + ZBUFF_endFrameSize : ensures it's always possible to write/flush/end a full block at best speed.

-/*******************************************************************************
-  Introduction
-
-  zstd, short for Zstandard, is a fast lossless compression algorithm, targeting
-  real-time compression scenarios at zlib-level and better compression ratios.
-  The zstd compression library provides in-memory compression and decompression
-  functions.
-
-  The library supports regular compression levels from 1 up to ZSTD_maxCLevel(),
-  which is currently 22. Levels >= 20, labeled `--ultra`, should be used with
-  caution, as they require more memory. The library also offers negative
-  compression levels, which extend the range of speed vs. ratio preferences.
-  The lower the level, the faster the speed (at the cost of compression).
-
-  Compression can be done in:
-    - a single step (described as Simple API)
-    - a single step, reusing a context (described as Explicit context)
-    - unbounded multiple steps (described as Streaming compression)
-
-  The compression ratio achievable on small data can be highly improved using
-  a dictionary. Dictionary compression can be performed in:
-    - a single step (described as Simple dictionary API)
-    - a single step, reusing a dictionary (described as Bulk-processing
-      dictionary API)
-
-  Advanced experimental functions can be accessed using
-  `#define ZSTD_STATIC_LINKING_ONLY` before including zstd.h.
-
-  Advanced experimental APIs should never be used with a dynamically-linked
-  library. They are not "stable"; their definitions or signatures may change in
-  the future. Only static linking is allowed.

-*  Streaming compression - HowTo
-*
-*  A ZSTD_CStream object is required to track streaming operation.
-*  Use ZSTD_createCStream() and ZSTD_freeCStream() to create/release resources.
-*  ZSTD_CStream objects can be reused multiple times on consecutive compression operations.
-*  It is recommended to re-use ZSTD_CStream since it will play nicer with system's memory, by re-using already allocated memory.
-*
-*  For parallel execution, use one separate ZSTD_CStream per thread.
-*
-*  note : since v1.3.0, ZSTD_CStream and ZSTD_CCtx are the same thing.
-*
-*  Parameters are sticky : when starting a new compression on the same context,
-*  it will re-use the same sticky parameters as previous compression session.
-*  When in doubt, it's recommended to fully initialize the context before usage.
-*  Use ZSTD_CCtx_reset() to reset the context and ZSTD_CCtx_setParameter(),
-*  ZSTD_CCtx_setPledgedSrcSize(), or ZSTD_CCtx_loadDictionary() and friends to
-*  set more specific parameters, the pledged source size, or load a dictionary.
-*
-*  Use ZSTD_compressStream2() with ZSTD_e_continue as many times as necessary to
-*  consume input stream. The function will automatically update both `pos`
-*  fields within `input` and `output`.
-*  Note that the function may not consume the entire input, for example, because
-*  the output buffer is already full, in which case `input.pos < input.size`.
-*  The caller must check if input has been entirely consumed.
-*  If not, the caller must make some room to receive more compressed data,
-*  and then present again remaining input data.
-*  note: ZSTD_e_continue is guaranteed to make some forward progress when called,
-*        but doesn't guarantee maximal forward progress. This is especially relevant
-*        when compressing with multiple threads. The call won't block if it can
-*        consume some input, but if it can't it will wait for some, but not all,
-*        output to be flushed.
-* @return : provides a minimum amount of data remaining to be flushed from internal buffers
-*           or an error code, which can be tested using ZSTD_isError().
-*
-*  At any moment, it's possible to flush whatever data might remain stuck within internal buffer,
-*  using ZSTD_compressStream2() with ZSTD_e_flush. `output->pos` will be updated.
-*  Note that, if `output->size` is too small, a single invocation with ZSTD_e_flush might not be enough (return code > 0).
-*  In which case, make some room to receive more compressed data, and call again ZSTD_compressStream2() with ZSTD_e_flush.
-*  You must continue calling ZSTD_compressStream2() with ZSTD_e_flush until it returns 0, at which point you can change the
-*  operation.
-*  note: ZSTD_e_flush will flush as much output as possible, meaning when compressing with multiple threads, it will
-*        block until the flush is complete or the output buffer is full.
-*  @return : 0 if internal buffers are entirely flushed,
-*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
-*            or an error code, which can be tested using ZSTD_isError().
-*
-*  Calling ZSTD_compressStream2() with ZSTD_e_end instructs to finish a frame.
-*  It will perform a flush and write frame epilogue.
-*  The epilogue is required for decoders to consider a frame completed.
-*  flush operation is the same, and follows same rules as calling ZSTD_compressStream2() with ZSTD_e_flush.
-*  You must continue calling ZSTD_compressStream2() with ZSTD_e_end until it returns 0, at which point you are free to
-*  start a new frame.
-*  note: ZSTD_e_end will flush as much output as possible, meaning when compressing with multiple threads, it will
-*        block until the flush is complete or the output buffer is full.
-*  @return : 0 if frame fully completed and fully flushed,
-*            >0 if some data still present within internal buffer (the value is minimal estimation of remaining size),
-*            or an error code, which can be tested using ZSTD_isError().

-*  Streaming decompression - HowTo
-*
-*  A ZSTD_DStream object is required to track streaming operations.
-*  Use ZSTD_createDStream() and ZSTD_freeDStream() to create/release resources.
-*  ZSTD_DStream objects can be re-used multiple times.
-*
-*  Use ZSTD_initDStream() to start a new decompression operation.
-* @return : recommended first input size
-*  Alternatively, use advanced API to set specific properties.
-*
-*  Use ZSTD_decompressStream() repetitively to consume your input.
-*  The function will update both `pos` fields.
-*  If `input.pos < input.size`, some input has not been consumed.
-*  It's up to the caller to present again remaining data.
-*  The function tries to flush all data decoded immediately, respecting output buffer size.
-*  If `output.pos < output.size`, decoder has flushed everything it could.
-*  But if `output.pos == output.size`, there might be some data left within internal buffers.,
-*  In which case, call ZSTD_decompressStream() again to flush whatever remains in the buffer.
-*  Note : with no additional input provided, amount of data flushed is necessarily <= ZSTD_BLOCKSIZE_MAX.
-* @return : 0 when a frame is completely decoded and fully flushed,
-*        or an error code, which can be tested using ZSTD_isError(),
-*        or any other value > 0, which means there is still some decoding or flushing to do to complete current frame :
-*                                the return value is a suggested next input size (just a hint for better latency)
-*                                that will never request more than the remaining frame size.

-     *   the cost of the compression.
-     *
-     * - The CDict's tables can be used in-place. In this model, compression is
-     *   slower per input byte, because the compressor has to search two sets of
-     *   tables. However, this model incurs no start-up cost (as long as the
-     *   working context's tables can be reused). For small inputs, this can be
-     *   faster than copying the CDict's tables.
-     *
-     * Zstd has a simple internal heuristic that selects which strategy to use
-     * at the beginning of a compression. However, if experimentation shows that
-     * Zstd is making poor choices, it is possible to override that choice with

-/**
-  Buffer-less streaming compression (synchronous mode)
-
-  A ZSTD_CCtx object is required to track streaming operations.
-  Use ZSTD_createCCtx() / ZSTD_freeCCtx() to manage resource.
-  ZSTD_CCtx object can be re-used multiple times within successive compression operations.
-
-  Start by initializing a context.
-  Use ZSTD_compressBegin(), or ZSTD_compressBegin_usingDict() for dictionary compression,
-  or ZSTD_compressBegin_advanced(), for finer parameter control.
-  It's also possible to duplicate a reference context which has already been initialized, using ZSTD_copyCCtx()
-
-  Then, consume your input using ZSTD_compressContinue().
-  There are some important considerations to keep in mind when using this advanced function :
-  - ZSTD_compressContinue() has no internal buffer. It uses externally provided buffers only.
-  - Interface is synchronous : input is consumed entirely and produces 1+ compressed blocks.
-  - Caller must ensure there is enough space in `dst` to store compressed data under worst case scenario.
-    Worst case evaluation is provided by ZSTD_compressBound().
-    ZSTD_compressContinue() doesn't guarantee recover after a failed compression.
-  - ZSTD_compressContinue() presumes prior input ***is still accessible and unmodified*** (up to maximum distance size, see WindowLog).
-    It remembers all previous contiguous blocks, plus one separated memory segment (which can itself consists of multiple contiguous blocks)
-  - ZSTD_compressContinue() detects that prior input has been overwritten when `src` buffer overlaps.
-    In which case, it will "discard" the relevant memory section from its history.
-
-  Finish a frame with ZSTD_compressEnd(), which will write the last block(s) and optional checksum.
-  It's possible to use srcSize==0, in which case, it will write a final empty block to end the frame.
-  Without last block mark, frames are considered unfinished (hence corrupted) by compliant decoders.
-
-  `ZSTD_CCtx` object can be re-used (ZSTD_compressBegin()) to compress again.

-  Buffer-less streaming decompression (synchronous mode)
-
-  A ZSTD_DCtx object is required to track streaming operations.
-  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it.
-  A ZSTD_DCtx object can be re-used multiple times.
-
-  First typical operation is to retrieve frame parameters, using ZSTD_getFrameHeader().
-  Frame header is extracted from the beginning of compressed frame, so providing only the frame's beginning is enough.
-  Data fragment must be large enough to ensure successful decoding.
- `ZSTD_frameHeaderSize_max` bytes is guaranteed to always be large enough.
-  @result : 0 : successful decoding, the `ZSTD_frameHeader` structure is correctly filled.
-           >0 : `srcSize` is too small, please provide at least @result bytes on next attempt.
-           errorCode, which can be tested using ZSTD_isError().
-
-  It fills a ZSTD_frameHeader structure with important information to correctly decode the frame,
-  such as the dictionary ID, content size, or maximum back-reference distance (`windowSize`).
-  Note that these values could be wrong, either because of data corruption, or because a 3rd party deliberately spoofs false information.
-  As a consequence, check that values remain within valid application range.
-  For example, do not allocate memory blindly, check that `windowSize` is within expectation.
-  Each application can set its own limits, depending on local restrictions.
-  For extended interoperability, it is recommended to support `windowSize` of at least 8 MB.
-
-  ZSTD_decompressContinue() needs previous data blocks during decompression, up to `windowSize` bytes.
-  ZSTD_decompressContinue() is very sensitive to contiguity,
-  if 2 blocks don't follow each other, make sure that either the compressor breaks contiguity at the same place,
-  or that previous contiguous segment is large enough to properly handle maximum back-reference distance.
-  There are multiple ways to guarantee this condition.
-
-  The most memory efficient way is to use a round buffer of sufficient size.
-  Sufficient size is determined by invoking ZSTD_decodingBufferSize_min(),
-  which can @return an error code if required value is too large for current system (in 32-bits mode).
-  In a round buffer methodology, ZSTD_decompressContinue() decompresses each block next to previous one,
-  up to the moment there is not enough room left in the buffer to guarantee decoding another full block,
-  which maximum size is provided in `ZSTD_frameHeader` structure, field `blockSizeMax`.
-  At which point, decoding can resume from the beginning of the buffer.
-  Note that already decoded data stored in the buffer should be flushed before being overwritten.
-
-  There are alternatives possible, for example using two or more buffers of size `windowSize` each, though they consume more memory.
-
-  Finally, if you control the compression process, you can also ignore all buffer size rules,
-  as long as the encoder and decoder progress in "lock-step",
-  aka use exactly the same buffer sizes, break contiguity at the same place, etc.
-
-  Once buffers are setup, start decompression, with ZSTD_decompressBegin().
-  If decompression requires a dictionary, use ZSTD_decompressBegin_usingDict() or ZSTD_decompressBegin_usingDDict().
-
-  Then use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
-  ZSTD_nextSrcSizeToDecompress() tells how many bytes to provide as 'srcSize' to ZSTD_decompressContinue().
-  ZSTD_decompressContinue() requires this _exact_ amount of bytes, or it will fail.
-
- @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity).
-  It can be zero : it just means ZSTD_decompressContinue() has decoded some metadata item.
-  It can also be an error code, which can be tested with ZSTD_isError().
-
-  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.
-
-  Note : it's possible to know if next input to present is a header or a block, using ZSTD_nextInputType().
-  This information is not required to properly decode a frame.
-
-  == Special case : skippable frames ==
-
-  Skippable frames allow integration of user-defined data into a flow of concatenated frames.
-  Skippable frames will be ignored (skipped) by decompressor.
-  The format of skippable frames is as follows :
-  a) Skippable frame ID - 4 Bytes, Little endian format, any value from 0x184D2A50 to 0x184D2A5F
-  b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
-  c) Frame Content - any content (User Data) of length equal to Frame Size
-  For skippable frames ZSTD_getFrameHeader() returns zfhPtr->frameType==ZSTD_skippableFrame.
-  For skippable frames ZSTD_decompressContinue() always returns 0 : it only skips the content.

-    Block functions produce and decode raw zstd blocks, without frame metadata.
-    Frame metadata cost is typically ~18 bytes, which can be non-negligible for very small blocks (< 100 bytes).
-    User will have to take in charge required information to regenerate data, such as compressed and content sizes.
-
-    A few rules to respect :
-    - Compressing and decompressing require a context structure
-      + Use ZSTD_createCCtx() and ZSTD_createDCtx()
-    - It is necessary to init context before starting
-      + compression : any ZSTD_compressBegin*() variant, including with dictionary
-      + decompression : any ZSTD_decompressBegin*() variant, including with dictionary
-      + copyCCtx() and copyDCtx() can be used too
-    - Block size is limited, it must be <= ZSTD_getBlockSize() <= ZSTD_BLOCKSIZE_MAX == 128 KB
-      + If input is larger than a block size, it's necessary to split input data into multiple blocks
-      + For inputs larger than a single block, really consider using regular ZSTD_compress() instead.
-        Frame metadata is not that costly, and quickly becomes negligible as source size grows larger.
-    - When a block is considered not compressible enough, ZSTD_compressBlock() result will be zero.
-      In which case, nothing is produced into `dst` !
-      + User must test for such outcome and deal directly with uncompressed data
-      + ZSTD_decompressBlock() doesn't accept uncompressed data as input !!!
-      + In case of multiple successive blocks, should some of them be uncompressed,
-        decoder must be informed of their existence in order to follow proper history.
-        Use ZSTD_insertBlock() for such a case.

-                                       It could be confused for a real successor at index "1", if sorted as larger than its predecessor.
-                                       It's not a big deal though : candidate will just be sorted again.
-                                       Additionally, candidate position 1 will be lost.

-                                       The benefit is that ZSTD_DUBT_UNSORTED_MARK cannot be mishandled after table re-use with a different strategy.

-/* MEM_FORCE_MEMORY_ACCESS
- * By default, access to unaligned memory is controlled by `memcpy()`, which is safe and portable.
- * Unfortunately, on some target/compiler combinations, the generated assembly is sub-optimal.
- * The below switch allow to select different access method for improved performance.
- * Method 0 (default) : use `memcpy()`. Safe and portable.
- * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
- *            This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
- * Method 2 : direct access. This method is portable but violate C standard.
- *            It can generate buggy code on targets generating assembly depending on alignment.
- *            But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
- * See http://fastcompression.blogspot.fr/2015/08/accessing-unaligned-memory.html for details.
- * Prefer these methods in priority order (0 > 1 > 2)

-  Use above functions alternatively.
-  ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTD_decompressContinue().
-  ZSTD_decompressContinue() will use previous data blocks to improve compression if they are located prior to current block.
-  Result is the number of bytes regenerated within 'dst'.
-  It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header.

- * By default, access to unaligned memory is controlled by `memcpy()`, which is safe and portable.

- * The below switch allow to select different access method for improved performance.
- * Method 0 (default) : use `memcpy()`. Safe and portable.
- * Method 1 : `__packed` statement. It depends on compiler extension (ie, not portable).
- *            This method is safe if your compiler supports it, and *generally* as fast or faster than `memcpy`.
- * Method 2 : direct access. This method is portable but violate C standard.
- *            It can generate buggy code on targets generating assembly depending on alignment.
- *            But in some circumstances, it's the only known way to get the most performance (ie GCC + ARMv6)
- * See http://fastcompression.blogspot.fr/2015/08/accessing-unaligned-memory.html for details.
- * Prefer these methods in priority order (0 > 1 > 2)

-  Streaming decompression, bufferless mode
-
-  A ZSTD_DCtx object is required to track streaming operations.
-  Use ZSTD_createDCtx() / ZSTD_freeDCtx() to manage it.
-  A ZSTD_DCtx object can be re-used multiple times. Use ZSTD_resetDCtx() to return to fresh status.
-
-  First operation is to retrieve frame parameters, using ZSTD_getFrameParams().
-  This function doesn't consume its input. It needs enough input data to properly decode the frame header.
-  Objective is to retrieve *params.windowlog, to know minimum amount of memory required during decoding.
-  Result : 0 when successful, it means the ZSTD_parameters structure has been filled.
-           >0 : means there is not enough data into src. Provides the expected size to successfully decode header.
-           errorCode, which can be tested using ZSTD_isError() (For example, if it's not a ZSTD header)
-
-  Then, you can optionally insert a dictionary.
-  This operation must mimic the compressor behavior, otherwise decompression will fail or be corrupted.
-
-  Then it's possible to start decompression.
-  Use ZSTD_nextSrcSizeToDecompress() and ZSTD_decompressContinue() alternatively.
-  ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTD_decompressContinue().
-  ZSTD_decompressContinue() requires this exact amount of bytes, or it will fail.
-  ZSTD_decompressContinue() needs previous data blocks during decompression, up to (1 << windowlog).
-  They should preferably be located contiguously, prior to current block. Alternatively, a round buffer is also possible.
-
-  @result of ZSTD_decompressContinue() is the number of bytes regenerated within 'dst'.
-  It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header.
-
-  A frame is fully decoded when ZSTD_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.

-Tutorial :
-----------
-(Note : these functions only decompress FSE-compressed blocks.
- If block is uncompressed, use memcpy() instead
- If block is a single repeated byte, use memset() instead )
-
-The first step is to obtain the normalized frequencies of symbols.
-This can be performed by FSE_readNCount() if it was saved using FSE_writeNCount().
-'normalizedCounter' must be already allocated, and have at least 'maxSymbolValuePtr[0]+1' cells of signed short.
-In practice, that means it's necessary to know 'maxSymbolValue' beforehand,
-or size the table to handle worst case situations (typically 256).
-FSE_readNCount() will provide 'tableLog' and 'maxSymbolValue'.
-The result of FSE_readNCount() is the number of bytes read from 'rBuffer'.
-Note that 'rBufferSize' must be at least 4 bytes, even if useful information is less than that.
-If there is an error, the function will return an error code, which can be tested using FSE_isError().
-
-The next step is to build the decompression tables 'FSE_DTable' from 'normalizedCounter'.
-This is performed by the function FSE_buildDTable().
-The space required by 'FSE_DTable' must be already allocated using FSE_createDTable().
-If there is an error, the function will return an error code, which can be tested using FSE_isError().
-
-'FSE_DTable' can then be used to decompress 'cSrc', with FSE_decompress_usingDTable().
-'cSrcSize' must be strictly correct, otherwise decompression will fail.
-FSE_decompress_usingDTable() result will tell how many bytes were regenerated (<=maxDstSize).
-If there is an error, the function will return an error code, which can be tested using FSE_isError(). (ex: dst buffer too small)

-/** ************************************************
-*  Streaming decompression
-*
-*  A ZBUFF_DCtx object is required to track streaming operation.
-*  Use ZBUFF_createDCtx() and ZBUFF_freeDCtx() to create/release resources.
-*  Use ZBUFF_decompressInit() to start a new decompression operation.
-*  ZBUFF_DCtx objects can be reused multiple times.
-*
-*  Use ZBUFF_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *maxDstSizePtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *maxDstSizePtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to call again the function with remaining input.
-*  The content of dst will be overwritten (up to *maxDstSizePtr) at each function call, so save its content if it matters or change dst .
-*  return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to improve latency)
-*            or 0 when a frame is completely decoded
-*            or an error code, which can be tested using ZBUFF_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory)
-*  output : 128 KB block size is the internal unit, it ensures it's always possible to write a full block when it's decoded.
-*  input : just follow indications from ZBUFF_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-*  It must be the same content as the one set during compression phase.
-*  Dictionary content must remain accessible during the decompression process.
-*
-*  Use ZBUFF_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *maxDstSizePtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *maxDstSizePtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of dst will be overwritten (up to *maxDstSizePtr) at each function call, so save its content if it matters or change dst.

-*  Hint : recommended buffer sizes (not compulsory) : ZBUFF_recommendedDInSize / ZBUFF_recommendedDOutSize
-*  output : ZBUFF_recommendedDOutSize==128 KB block size is the internal unit, it ensures it's always possible to write a full block when it's decoded.

-  Streaming decompression, direct mode (bufferless)
-
-  A ZSTDv05_DCtx object is required to track streaming operations.
-  Use ZSTDv05_createDCtx() / ZSTDv05_freeDCtx() to manage it.
-  A ZSTDv05_DCtx object can be re-used multiple times.
-
-  First typical operation is to retrieve frame parameters, using ZSTDv05_getFrameParams().
-  This operation is independent, and just needs enough input data to properly decode the frame header.
-  Objective is to retrieve *params.windowlog, to know minimum amount of memory required during decoding.
-  Result : 0 when successful, it means the ZSTDv05_parameters structure has been filled.
-           >0 : means there is not enough data into src. Provides the expected size to successfully decode header.
-           errorCode, which can be tested using ZSTDv05_isError()
-
-  Start decompression, with ZSTDv05_decompressBegin() or ZSTDv05_decompressBegin_usingDict()
-  Alternatively, you can copy a prepared context, using ZSTDv05_copyDCtx()
-
-  Then use ZSTDv05_nextSrcSizeToDecompress() and ZSTDv05_decompressContinue() alternatively.
-  ZSTDv05_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTDv05_decompressContinue().
-  ZSTDv05_decompressContinue() requires this exact amount of bytes, or it will fail.
-  ZSTDv05_decompressContinue() needs previous data blocks during decompression, up to (1 << windowlog).
-  They should preferably be located contiguously, prior to current block. Alternatively, a round buffer is also possible.
-
-  @result of ZSTDv05_decompressContinue() is the number of bytes regenerated within 'dst'.
-  It can be zero, which is not an error; it just means ZSTDv05_decompressContinue() has decoded some header.
-
-  A frame is fully decoded when ZSTDv05_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.

-/*! Block functions produce and decode raw zstd blocks, without frame metadata.

-
-    A few rules to respect :
-    - Uncompressed block size must be <= 128 KB
-    - Compressing or decompressing requires a context structure
-      + Use ZSTDv05_createCCtx() and ZSTDv05_createDCtx()
-    - It is necessary to init context before starting
-      + compression : ZSTDv05_compressBegin()
-      + decompression : ZSTDv05_decompressBegin()
-      + variants _usingDict() are also allowed
-      + copyCCtx() and copyDCtx() work too
-    - When a block is considered not compressible enough, ZSTDv05_compressBlock() result will be zero.
-      In which case, nothing is produced into `dst`.
-      + User must test for such outcome and deal directly with uncompressed data
-      + ZSTDv05_decompressBlock() doesn't accept uncompressed data as input !!

-*  Streaming decompression
-*
-*  A ZBUFFv05_DCtx object is required to track streaming operation.
-*  Use ZBUFFv05_createDCtx() and ZBUFFv05_freeDCtx() to create/release resources.
-*  Use ZBUFFv05_decompressInit() to start a new decompression operation.
-*  ZBUFFv05_DCtx objects can be reused multiple times.
-*
-*  Use ZBUFFv05_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *maxDstSizePtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *maxDstSizePtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to call again the function with remaining input.
-*  The content of dst will be overwritten (up to *maxDstSizePtr) at each function call, so save its content if it matters or change dst .
-*  return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to improve latency)
-*            or 0 when a frame is completely decoded
-*            or an error code, which can be tested using ZBUFFv05_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory)
-*  output : 128 KB block size is the internal unit, it ensures it's always possible to write a full block when it's decoded.
-*  input : just follow indications from ZBUFFv05_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-*  Streaming decompression
-*
-*  A ZBUFFv05_DCtx object is required to track streaming operations.

-*  Use ZBUFFv05_decompressInit() to start a new decompression operation,
-*   or ZBUFFv05_decompressInitDictionary() if decompression requires a dictionary.
-*  Note that ZBUFFv05_DCtx objects can be reused multiple times.
-*
-*  Use ZBUFFv05_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of @dst will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters or change @dst.
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to help latency)
-*            or 0 when a frame is completely decoded
-*            or an error code, which can be tested using ZBUFFv05_isError().

-*  output : ZBUFFv05_recommendedDOutSize==128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
-*  input  : ZBUFFv05_recommendedDInSize==128Kb+3; just follow indications from ZBUFFv05_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-  Streaming decompression, direct mode (bufferless)
-
-  A ZSTDv06_DCtx object is required to track streaming operations.
-  Use ZSTDv06_createDCtx() / ZSTDv06_freeDCtx() to manage it.
-  A ZSTDv06_DCtx object can be re-used multiple times.
-
-  First optional operation is to retrieve frame parameters, using ZSTDv06_getFrameParams(), which doesn't consume the input.
-  It can provide the minimum size of rolling buffer required to properly decompress data,
-  and optionally the final size of uncompressed content.
-  (Note : content size is an optional info that may not be present. 0 means : content size unknown)
-  Frame parameters are extracted from the beginning of compressed frame.
-  The amount of data to read is variable, from ZSTDv06_frameHeaderSize_min to ZSTDv06_frameHeaderSize_max (so if `srcSize` >= ZSTDv06_frameHeaderSize_max, it will always work)
-  If `srcSize` is too small for operation to succeed, function will return the minimum size it requires to produce a result.
-  Result : 0 when successful, it means the ZSTDv06_frameParams structure has been filled.
-          >0 : means there is not enough data into `src`. Provides the expected size to successfully decode header.
-           errorCode, which can be tested using ZSTDv06_isError()
-
-  Start decompression, with ZSTDv06_decompressBegin() or ZSTDv06_decompressBegin_usingDict().
-  Alternatively, you can copy a prepared context, using ZSTDv06_copyDCtx().
-
-  Then use ZSTDv06_nextSrcSizeToDecompress() and ZSTDv06_decompressContinue() alternatively.
-  ZSTDv06_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTDv06_decompressContinue().
-  ZSTDv06_decompressContinue() requires this exact amount of bytes, or it will fail.
-  ZSTDv06_decompressContinue() needs previous data blocks during decompression, up to (1 << windowlog).
-  They should preferably be located contiguously, prior to current block. Alternatively, a round buffer is also possible.
-
-  @result of ZSTDv06_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity)
-  It can be zero, which is not an error; it just means ZSTDv06_decompressContinue() has decoded some header.
-
-  A frame is fully decoded when ZSTDv06_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.

-/* **************************************
-*  Block functions
-****************************************/
-/*! Block functions produce and decode raw zstd blocks, without frame metadata.
-    User will have to take in charge required information to regenerate data, such as compressed and content sizes.
-
-    A few rules to respect :
-    - Uncompressed block size must be <= ZSTDv06_BLOCKSIZE_MAX (128 KB)
-    - Compressing or decompressing requires a context structure
-      + Use ZSTDv06_createCCtx() and ZSTDv06_createDCtx()
-    - It is necessary to init context before starting
-      + compression : ZSTDv06_compressBegin()
-      + decompression : ZSTDv06_decompressBegin()
-      + variants _usingDict() are also allowed
-      + copyCCtx() and copyDCtx() work too
-    - When a block is considered not compressible enough, ZSTDv06_compressBlock() result will be zero.
-      In which case, nothing is produced into `dst`.
-      + User must test for such outcome and deal directly with uncompressed data
-      + ZSTDv06_decompressBlock() doesn't accept uncompressed data as input !!

-Tutorial :
-----------
-(Note : these functions only decompress FSE-compressed blocks.
- If block is uncompressed, use memcpy() instead
- If block is a single repeated byte, use memset() instead )
-
-The first step is to obtain the normalized frequencies of symbols.
-This can be performed by FSEv06_readNCount() if it was saved using FSEv06_writeNCount().
-'normalizedCounter' must be already allocated, and have at least 'maxSymbolValuePtr[0]+1' cells of signed short.
-In practice, that means it's necessary to know 'maxSymbolValue' beforehand,
-or size the table to handle worst case situations (typically 256).
-FSEv06_readNCount() will provide 'tableLog' and 'maxSymbolValue'.
-The result of FSEv06_readNCount() is the number of bytes read from 'rBuffer'.
-Note that 'rBufferSize' must be at least 4 bytes, even if useful information is less than that.
-If there is an error, the function will return an error code, which can be tested using FSEv06_isError().
-
-The next step is to build the decompression tables 'FSEv06_DTable' from 'normalizedCounter'.
-This is performed by the function FSEv06_buildDTable().
-The space required by 'FSEv06_DTable' must be already allocated using FSEv06_createDTable().
-If there is an error, the function will return an error code, which can be tested using FSEv06_isError().
-
-`FSEv06_DTable` can then be used to decompress `cSrc`, with FSEv06_decompress_usingDTable().
-`cSrcSize` must be strictly correct, otherwise decompression will fail.
-FSEv06_decompress_usingDTable() result will tell how many bytes were regenerated (<=`dstCapacity`).
-If there is an error, the function will return an error code, which can be tested using FSEv06_isError(). (ex: dst buffer too small)

-*  Streaming decompression howto
-*
-*  A ZBUFFv06_DCtx object is required to track streaming operations.
-*  Use ZBUFFv06_createDCtx() and ZBUFFv06_freeDCtx() to create/release resources.
-*  Use ZBUFFv06_decompressInit() to start a new decompression operation,
-*   or ZBUFFv06_decompressInitDictionary() if decompression requires a dictionary.
-*  Note that ZBUFFv06_DCtx objects can be re-init multiple times.
-*
-*  Use ZBUFFv06_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of @dst will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters, or change @dst.
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to help latency),
-*            or 0 when a frame is completely decoded,
-*            or an error code, which can be tested using ZBUFFv06_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory) : ZBUFFv06_recommendedDInSize() and ZBUFFv06_recommendedDOutSize()
-*  output : ZBUFFv06_recommendedDOutSize==128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
-*  input  : ZBUFFv06_recommendedDInSize == 128KB + 3;
-*           just follow indications from ZBUFFv06_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-*  Streaming decompression howto
-*
-*  A ZBUFFv06_DCtx object is required to track streaming operations.
-*  Use ZBUFFv06_createDCtx() and ZBUFFv06_freeDCtx() to create/release resources.
-*  Use ZBUFFv06_decompressInit() to start a new decompression operation,
-*   or ZBUFFv06_decompressInitDictionary() if decompression requires a dictionary.
-*  Note that ZBUFFv06_DCtx objects can be re-init multiple times.
-*
-*  Use ZBUFFv06_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters, or change `dst`.
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to help latency),
-*            or 0 when a frame is completely decoded,
-*            or an error code, which can be tested using ZBUFFv06_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory) : ZBUFFv06_recommendedDInSize() and ZBUFFv06_recommendedDOutSize()
-*  output : ZBUFFv06_recommendedDOutSize== 128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
-*  input  : ZBUFFv06_recommendedDInSize == 128KB + 3;
-*           just follow indications from ZBUFFv06_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-  Buffer-less streaming decompression (synchronous mode)
-
-  A ZSTDv07_DCtx object is required to track streaming operations.
-  Use ZSTDv07_createDCtx() / ZSTDv07_freeDCtx() to manage it.
-  A ZSTDv07_DCtx object can be re-used multiple times.
-
-  First optional operation is to retrieve frame parameters, using ZSTDv07_getFrameParams(), which doesn't consume the input.
-  It can provide the minimum size of rolling buffer required to properly decompress data (`windowSize`),
-  and optionally the final size of uncompressed content.
-  (Note : content size is an optional info that may not be present. 0 means : content size unknown)
-  Frame parameters are extracted from the beginning of compressed frame.
-  The amount of data to read is variable, from ZSTDv07_frameHeaderSize_min to ZSTDv07_frameHeaderSize_max (so if `srcSize` >= ZSTDv07_frameHeaderSize_max, it will always work)
-  If `srcSize` is too small for operation to succeed, function will return the minimum size it requires to produce a result.
-  Result : 0 when successful, it means the ZSTDv07_frameParams structure has been filled.
-          >0 : means there is not enough data into `src`. Provides the expected size to successfully decode header.
-           errorCode, which can be tested using ZSTDv07_isError()
-
-  Start decompression, with ZSTDv07_decompressBegin() or ZSTDv07_decompressBegin_usingDict().
-  Alternatively, you can copy a prepared context, using ZSTDv07_copyDCtx().
-
-  Then use ZSTDv07_nextSrcSizeToDecompress() and ZSTDv07_decompressContinue() alternatively.
-  ZSTDv07_nextSrcSizeToDecompress() tells how much bytes to provide as 'srcSize' to ZSTDv07_decompressContinue().
-  ZSTDv07_decompressContinue() requires this exact amount of bytes, or it will fail.
-
-  @result of ZSTDv07_decompressContinue() is the number of bytes regenerated within 'dst' (necessarily <= dstCapacity).
-  It can be zero, which is not an error; it just means ZSTDv07_decompressContinue() has decoded some header.
-
-  ZSTDv07_decompressContinue() needs previous data blocks during decompression, up to `windowSize`.
-  They should preferably be located contiguously, prior to current block.
-  Alternatively, a round buffer of sufficient size is also possible. Sufficient size is determined by frame parameters.
-  ZSTDv07_decompressContinue() is very sensitive to contiguity,
-  if 2 blocks don't follow each other, make sure that either the compressor breaks contiguity at the same place,
-    or that previous contiguous segment is large enough to properly handle maximum back-reference.
-
-  A frame is fully decoded when ZSTDv07_nextSrcSizeToDecompress() returns zero.
-  Context can then be reset to start a new decompression.
-
-
-  == Special case : skippable frames ==
-
-  Skippable frames allow the integration of user-defined data into a flow of concatenated frames.
-  Skippable frames will be ignored (skipped) by a decompressor. The format of skippable frame is following:
-  a) Skippable frame ID - 4 Bytes, Little endian format, any value from 0x184D2A50 to 0x184D2A5F
-  b) Frame Size - 4 Bytes, Little endian format, unsigned 32-bits
-  c) Frame Content - any content (User Data) of length equal to Frame Size
-  For skippable frames ZSTDv07_decompressContinue() always returns 0.
-  For skippable frames ZSTDv07_getFrameParams() returns fparamsPtr->windowLog==0 what means that a frame is skippable.
-  It also returns Frame Size as fparamsPtr->frameContentSize.

-
-/* **************************************
-*  Block functions
-****************************************/
-/*! Block functions produce and decode raw zstd blocks, without frame metadata.
-    Frame metadata cost is typically ~18 bytes, which can be non-negligible for very small blocks (< 100 bytes).
-    User will have to take in charge required information to regenerate data, such as compressed and content sizes.
-
-    A few rules to respect :
-    - Compressing and decompressing require a context structure
-      + Use ZSTDv07_createCCtx() and ZSTDv07_createDCtx()
-    - It is necessary to init context before starting
-      + compression : ZSTDv07_compressBegin()
-      + decompression : ZSTDv07_decompressBegin()
-      + variants _usingDict() are also allowed
-      + copyCCtx() and copyDCtx() work too
-    - Block size is limited, it must be <= ZSTDv07_getBlockSizeMax()
-      + If you need to compress more, cut data into multiple blocks
-      + Consider using the regular ZSTDv07_compress() instead, as frame metadata costs become negligible when source size is large.
-    - When a block is considered not compressible enough, ZSTDv07_compressBlock() result will be zero.
-      In which case, nothing is produced into `dst`.
-      + User must test for such outcome and deal directly with uncompressed data
-      + ZSTDv07_decompressBlock() doesn't accept uncompressed data as input !!!
-      + In case of multiple successive blocks, decoder must be informed of uncompressed block existence to follow proper history.
-        Use ZSTDv07_insertBlock() in such a case.

-Tutorial :
-----------
-(Note : these functions only decompress FSE-compressed blocks.
- If block is uncompressed, use memcpy() instead
- If block is a single repeated byte, use memset() instead )
-
-The first step is to obtain the normalized frequencies of symbols.
-This can be performed by FSEv07_readNCount() if it was saved using FSEv07_writeNCount().
-'normalizedCounter' must be already allocated, and have at least 'maxSymbolValuePtr[0]+1' cells of signed short.
-In practice, that means it's necessary to know 'maxSymbolValue' beforehand,
-or size the table to handle worst case situations (typically 256).
-FSEv07_readNCount() will provide 'tableLog' and 'maxSymbolValue'.
-The result of FSEv07_readNCount() is the number of bytes read from 'rBuffer'.
-Note that 'rBufferSize' must be at least 4 bytes, even if useful information is less than that.
-If there is an error, the function will return an error code, which can be tested using FSEv07_isError().
-
-The next step is to build the decompression tables 'FSEv07_DTable' from 'normalizedCounter'.
-This is performed by the function FSEv07_buildDTable().
-The space required by 'FSEv07_DTable' must be already allocated using FSEv07_createDTable().
-If there is an error, the function will return an error code, which can be tested using FSEv07_isError().
-
-`FSEv07_DTable` can then be used to decompress `cSrc`, with FSEv07_decompress_usingDTable().
-`cSrcSize` must be strictly correct, otherwise decompression will fail.
-FSEv07_decompress_usingDTable() result will tell how many bytes were regenerated (<=`dstCapacity`).
-If there is an error, the function will return an error code, which can be tested using FSEv07_isError(). (ex: dst buffer too small)

-*  Streaming decompression howto
-*
-*  A ZBUFFv07_DCtx object is required to track streaming operations.
-*  Use ZBUFFv07_createDCtx() and ZBUFFv07_freeDCtx() to create/release resources.
-*  Use ZBUFFv07_decompressInit() to start a new decompression operation,
-*   or ZBUFFv07_decompressInitDictionary() if decompression requires a dictionary.
-*  Note that ZBUFFv07_DCtx objects can be re-init multiple times.
-*
-*  Use ZBUFFv07_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of @dst will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters, or change @dst.
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to help latency),
-*            or 0 when a frame is completely decoded,
-*            or an error code, which can be tested using ZBUFFv07_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory) : ZBUFFv07_recommendedDInSize() and ZBUFFv07_recommendedDOutSize()
-*  output : ZBUFFv07_recommendedDOutSize==128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
-*  input  : ZBUFFv07_recommendedDInSize == 128KB + 3;
-*           just follow indications from ZBUFFv07_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

-*  Streaming decompression howto
-*
-*  A ZBUFFv07_DCtx object is required to track streaming operations.
-*  Use ZBUFFv07_createDCtx() and ZBUFFv07_freeDCtx() to create/release resources.
-*  Use ZBUFFv07_decompressInit() to start a new decompression operation,
-*   or ZBUFFv07_decompressInitDictionary() if decompression requires a dictionary.
-*  Note that ZBUFFv07_DCtx objects can be re-init multiple times.
-*
-*  Use ZBUFFv07_decompressContinue() repetitively to consume your input.
-*  *srcSizePtr and *dstCapacityPtr can be any size.
-*  The function will report how many bytes were read or written by modifying *srcSizePtr and *dstCapacityPtr.
-*  Note that it may not consume the entire input, in which case it's up to the caller to present remaining input again.
-*  The content of `dst` will be overwritten (up to *dstCapacityPtr) at each function call, so save its content if it matters, or change `dst`.
-*  @return : a hint to preferred nb of bytes to use as input for next function call (it's only a hint, to help latency),
-*            or 0 when a frame is completely decoded,
-*            or an error code, which can be tested using ZBUFFv07_isError().
-*
-*  Hint : recommended buffer sizes (not compulsory) : ZBUFFv07_recommendedDInSize() and ZBUFFv07_recommendedDOutSize()
-*  output : ZBUFFv07_recommendedDOutSize== 128 KB block size is the internal unit, it ensures it's always possible to write a full block when decoded.
-*  input  : ZBUFFv07_recommendedDInSize == 128KB + 3;
-*           just follow indications from ZBUFFv07_decompressContinue() to minimize latency. It should always be <= 128 KB + 3 .

 Sarama is an MIT-licensed Go client library for [Apache Kafka](https://kafka.apache.org/) version 0.8 (and later).
 
-### Getting started
+## Getting started
 
-- API documentation and examples are available via [godoc](https://godoc.org/github.com/Shopify/sarama).
+- API documentation and examples are available via [pkg.go.dev](https://pkg.go.dev/github.com/Shopify/sarama).
 - Mocks for testing are available in the [mocks](./mocks) subpackage.
 - The [examples](./examples) directory contains more elaborate example applications.
 - The [tools](./tools) directory contains command line tools that can be useful for testing, diagnostics, and instrumentation.
 
 You might also want to look at the [Frequently Asked Questions](https://github.com/Shopify/sarama/wiki/Frequently-Asked-Questions).
 
-### Compatibility and API stability
+## Compatibility and API stability
 
 Sarama provides a "2 releases + 2 months" compatibility guarantee: we support
 the two latest stable releases of Kafka and Go, and we provide a two month
 grace period for older releases. This means we currently officially support
-Go 1.11 through 1.12, and Kafka 2.0 through 2.3, although older releases are
+Go 1.15 through 1.16, and Kafka 2.6 through 2.8, although older releases are
 still likely to work.
 
 Sarama follows semantic versioning and provides API stability via the gopkg.in service.
 You can import a version with a guaranteed stable API via http://gopkg.in/Shopify/sarama.v1.
 A changelog is available [here](CHANGELOG.md).

-This library provides a consistent hashing function which simultaneously achieves both uniformity and consistency. 
-
-For detailed information about the concept, you should take a look at the following resources:
-

-Overview
---------
-
-In this package's context, the keys are distributed among partitions and partitions are distributed among members as well. 
-
-When you create a new consistent instance or call `Add/Remove`:
-
-* The member's name is hashed and inserted into the hash ring,
-* Average load is calculated by the algorithm defined in the paper,
-* Partitions are distributed among members by hashing partition IDs and none of them exceed the average load.
-
-Average load cannot be exceeded. So if all members are loaded at the maximum while trying to add a new member, it panics.
-
-When you want to locate a key by calling `LocateKey`:
-
-* The key(byte slice) is hashed,
-* The result of the hash is mod by the number of partitions,
-* The result of this modulo - `MOD(hash result, partition count)` - is the partition in which the key will be located,
-* Owner of the partition is already determined before calling `LocateKey`. So it returns the partition owner immediately.
-
-No memory is allocated by `consistent` except hashing when you want to locate a key.
-
-Note that the number of partitions cannot be changed after creation. 
-
-Install
--------
-
-With a correctly configured Go environment:
-
-```
-go get github.com/buraksezer/consistent
-```
-
-You will find some useful usage samples in [examples](https://github.com/buraksezer/consistent/tree/master/_examples) folder.
-
-Configuration
--------------
-
-```go
-type Config struct {
-	// Hasher is responsible for generating unsigned, 64 bit hash of provided byte slice.
-	Hasher Hasher
-
-	// Keys are distributed among partitions. Prime numbers are good to
-	// distribute keys uniformly. Select a big PartitionCount if you have
-	// too many keys.
-	PartitionCount int
-
-	// Members are replicated on consistent hash ring. This number controls
-	// the number each member is replicated on the ring.
-	ReplicationFactor int
-
-	// Load is used to calculate average load. See the code, the paper and Google's 
-	// blog post to learn about it.
-	Load float64
-}
-```
-
-Any hash algorithm can be used as hasher which implements Hasher interface. Please take a look at the *Sample* section for an example.
-
-Usage
------
-
-`LocateKey` function finds a member in the cluster for your key:
-```go
-// With a properly configured and initialized consistent instance
-key := []byte("my-key")
-member := c.LocateKey(key)
-```
-It returns a thread-safe copy of the member you added before.
-
-The second most frequently used function is `GetClosestN`. 
-
-```go
-// With a properly configured and initialized consistent instance
-
-key := []byte("my-key")
-members, err := c.GetClosestN(key, 2)
-```
-
-This may be useful to find backup nodes to store your key.
-
-Benchmarks
-----------
-On an early 2015 Macbook:
-
-```
-BenchmarkAddRemove-4     	  100000	     22006 ns/op
-BenchmarkLocateKey-4     	 5000000	       252 ns/op
-BenchmarkGetClosestN-4   	  500000	      2974 ns/op
-```
-
-Examples
---------
-
-The most basic use of consistent package should be like this. For detailed list of functions, [visit godoc.org.](https://godoc.org/github.com/buraksezer/consistent)
-More sample code can be found under [_examples](https://github.com/buraksezer/consistent/tree/master/_examples).
-
-```go
-package main
-
-import (
-	"fmt"
-
-	"github.com/buraksezer/consistent"
-	"github.com/cespare/xxhash"
-)
-
-// In your code, you probably have a custom data type 
-// for your cluster members. Just add a String function to implement 
-// consistent.Member interface.
-type myMember string
-
-func (m myMember) String() string {
-	return string(m)
-}
-
-// consistent package doesn't provide a default hashing function. 
-// You should provide a proper one to distribute keys/members uniformly.
-type hasher struct{}
-
-func (h hasher) Sum64(data []byte) uint64 {
-	// you should use a proper hash function for uniformity.
-	return xxhash.Sum64(data)
-}
-
-func main() {
-	// Create a new consistent instance
-	cfg := consistent.Config{
-		PartitionCount:    7,
-		ReplicationFactor: 20,
-		Load:              1.25,
-		Hasher:            hasher{},
-	}
-	c := consistent.New(nil, cfg)
-
-	// Add some members to the consistent hash table.
-	// Add function calculates average load and distributes partitions over members
-	node1 := myMember("node1.olric.com")
-	c.Add(node1)
-
-	node2 := myMember("node2.olric.com")
-	c.Add(node2)
-
-	key := []byte("my-key")
-	// calculates partition id for the given key
-	// partID := hash(key) % partitionCount
-	// the partitions are already distributed among members by Add function.
-	owner := c.LocateKey(key)
-	fmt.Println(owner.String())
-	// Prints node2.olric.com
-}
-```
-
-Another useful example is `_examples/relocation_percentage.go`. It creates a `consistent` object with 8 members and distributes partitions among them. Then adds 9th member, 
-here is the result with a proper configuration and hash function:
-
-```
-bloom:consistent burak$ go run _examples/relocation_percentage.go
-partID: 218 moved to node2.olric from node0.olric
-partID: 173 moved to node9.olric from node3.olric
-partID: 225 moved to node7.olric from node0.olric
-partID:  85 moved to node9.olric from node7.olric
-partID: 220 moved to node5.olric from node0.olric
-partID:  33 moved to node9.olric from node5.olric
-partID: 254 moved to node9.olric from node4.olric
-partID:  71 moved to node9.olric from node3.olric
-partID: 236 moved to node9.olric from node2.olric
-partID: 118 moved to node9.olric from node3.olric
-partID: 233 moved to node3.olric from node0.olric
-partID:  50 moved to node9.olric from node4.olric
-partID: 252 moved to node9.olric from node2.olric
-partID: 121 moved to node9.olric from node2.olric
-partID: 259 moved to node9.olric from node4.olric
-partID:  92 moved to node9.olric from node7.olric
-partID: 152 moved to node9.olric from node3.olric
-partID: 105 moved to node9.olric from node2.olric
-
-6% of the partitions are relocated
-```
-
-Moved partition count is highly dependent on your configuration and quailty of hash function. You should modify the configuration to find an optimum set of configurations
-for your system.
-
-`_examples/load_distribution.go` is also useful to understand load distribution. It creates a `consistent` object with 8 members and locates 1M key. It also calculates average 
-load which cannot be exceeded by any member. Here is the result:
-
-```
-Maximum key count for a member should be around this:  147602
-member: node2.olric, key count: 100362
-member: node5.olric, key count: 99448
-member: node0.olric, key count: 147735
-member: node3.olric, key count: 103455
-member: node6.olric, key count: 147069
-member: node1.olric, key count: 121566
-member: node4.olric, key count: 147932
-member: node7.olric, key count: 132433
-```
-
-Average load can be calculated by using the following formula:
-
-```
-load := (consistent.AverageLoad() * float64(keyCount)) / float64(config.PartitionCount)
-```

+# xxhash
+
+[![GoDoc](https://godoc.org/github.com/cespare/xxhash?status.svg)](https://godoc.org/github.com/cespare/xxhash)
+[![Build Status](https://travis-ci.org/cespare/xxhash.svg?branch=master)](https://travis-ci.org/cespare/xxhash)
+
+xxhash is a Go implementation of the 64-bit
+[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
+high-quality hashing algorithm that is much faster than anything in the Go
+standard library.
+
+This package provides a straightforward API:
+
+```
+func Sum64(b []byte) uint64
+func Sum64String(s string) uint64
+type Digest struct{ ... }
+    func New() *Digest
+```
+
+The `Digest` type implements hash.Hash64. Its key methods are:
+
+```
+func (*Digest) Write([]byte) (int, error)
+func (*Digest) WriteString(string) (int, error)
+func (*Digest) Sum64() uint64
+```
+
+This implementation provides a fast pure-Go implementation and an even faster
+assembly implementation for amd64.
+
+## Compatibility
+
+This package is in a module and the latest code is in version 2 of the module.
+You need a version of Go with at least "minimal module compatibility" to use
+github.com/cespare/xxhash/v2:
+
+* 1.9.7+ for Go 1.9
+* 1.10.3+ for Go 1.10
+* Go 1.11 or later
+
+I recommend using the latest release of Go.
+
+## Benchmarks
+
+Here are some quick benchmarks comparing the pure-Go and assembly
+implementations of Sum64.

+| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
+
+These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
+the following commands under Go 1.11.2:
+
+```
+$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
+$ go test -benchtime 10s -bench '/xxhash,direct,bytes'

+
+bbolt is a fork of [Ben Johnson's][gh_ben] [Bolt][bolt] key/value
+store. The purpose of this fork is to provide the Go community with an active
+maintenance and development target for Bolt; the goal is improved reliability
+and stability. bbolt includes bug fixes, performance enhancements, and features
+not found in Bolt while preserving backwards compatibility with the Bolt API.
+
+Bolt is a pure Go key/value store inspired by [Howard Chu's][hyc_symas]
+[LMDB project][lmdb]. The goal of the project is to provide a simple,
+fast, and reliable database for projects that don't require a full database
+server such as Postgres or MySQL.
+
+Since Bolt is meant to be used as such a low-level piece of functionality,
+simplicity is key. The API will be small and only focus on getting values
+and setting values. That's it.
+

+[bolt]: https://github.com/boltdb/bolt
+[hyc_symas]: https://twitter.com/hyc_symas
+[lmdb]: http://symas.com/mdb/
+
+## Project Status
+
+Bolt is stable, the API is fixed, and the file format is fixed. Full unit
+test coverage and randomized black box testing are used to ensure database

+
+## Getting Started
+
+### Installing
+
+To start using Bolt, install Go and run `go get`:
+
+```sh
+$ go get go.etcd.io/bbolt/...
+```
+
+This will retrieve the library and install the `bolt` command line utility into
+your `$GOBIN` path.
+
+
+### Importing bbolt
+
+To use bbolt as an embedded key-value store, import as:
+
+```go
+import bolt "go.etcd.io/bbolt"
+
+db, err := bolt.Open(path, 0666, nil)
+if err != nil {
+  return err
+}
+defer db.Close()
+```
+
+
+### Opening a database
+
+The top-level object in Bolt is a `DB`. It is represented as a single file on
+your disk and represents a consistent snapshot of your data.
+
+To open your database, simply use the `bolt.Open()` function:
+
+```go
+package main
+
+import (
+	"log"
+
+	bolt "go.etcd.io/bbolt"
+)
+
+func main() {
+	// Open the my.db data file in your current directory.
+	// It will be created if it doesn't exist.
+	db, err := bolt.Open("my.db", 0600, nil)
+	if err != nil {
+		log.Fatal(err)
+	}
+	defer db.Close()
+
+	...
+}
+```
+
+Please note that Bolt obtains a file lock on the data file so multiple processes
+cannot open the same database at the same time. Opening an already open Bolt
+database will cause it to hang until the other process closes it. To prevent
+an indefinite wait you can pass a timeout option to the `Open()` function:
+
+```go
+db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second})
+```
+
+
+### Transactions
+
+Bolt allows only one read-write transaction at a time but allows as many
+read-only transactions as you want at a time. Each transaction has a consistent
+view of the data as it existed when the transaction started.
+
+Individual transactions and all objects created from them (e.g. buckets, keys)
+are not thread safe. To work with data in multiple goroutines you must start
+a transaction for each one or use locking to ensure only one goroutine accesses
+a transaction at a time. Creating transaction from the `DB` is thread safe.
+
+Read-only transactions and read-write transactions should not depend on one
+another and generally shouldn't be opened simultaneously in the same goroutine.
+This can cause a deadlock as the read-write transaction needs to periodically
+re-map the data file but it cannot do so while a read-only transaction is open.
+
+
+#### Read-write transactions
+
+To start a read-write transaction, you can use the `DB.Update()` function:
+
+```go
+err := db.Update(func(tx *bolt.Tx) error {
+	...
+	return nil
+})
+```
+
+Inside the closure, you have a consistent view of the database. You commit the
+transaction by returning `nil` at the end. You can also rollback the transaction
+at any point by returning an error. All database operations are allowed inside
+a read-write transaction.
+
+Always check the return error as it will report any disk failures that can cause
+your transaction to not complete. If you return an error within your closure
+it will be passed through.
+
+
+#### Read-only transactions
+
+To start a read-only transaction, you can use the `DB.View()` function:
+
+```go
+err := db.View(func(tx *bolt.Tx) error {
+	...
+	return nil
+})
+```
+
+You also get a consistent view of the database within this closure, however,
+no mutating operations are allowed within a read-only transaction. You can only
+retrieve buckets, retrieve values, and copy the database within a read-only
+transaction.
+
+
+#### Batch read-write transactions
+
+Each `DB.Update()` waits for disk to commit the writes. This overhead
+can be minimized by combining multiple updates with the `DB.Batch()`
+function:
+
+```go
+err := db.Batch(func(tx *bolt.Tx) error {
+	...
+	return nil
+})
+```
+
+Concurrent Batch calls are opportunistically combined into larger
+transactions. Batch is only useful when there are multiple goroutines
+calling it.
+
+The trade-off is that `Batch` can call the given
+function multiple times, if parts of the transaction fail. The
+function must be idempotent and side effects must take effect only
+after a successful return from `DB.Batch()`.
+
+For example: don't display messages from inside the function, instead
+set variables in the enclosing scope:
+
+```go
+var id uint64
+err := db.Batch(func(tx *bolt.Tx) error {
+	// Find last key in bucket, decode as bigendian uint64, increment
+	// by one, encode back to []byte, and add new key.
+	...
+	id = newValue
+	return nil
+})
+if err != nil {
+	return ...
+}
+fmt.Println("Allocated ID %d", id)
+```
+
+
+#### Managing transactions manually
+
+The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()`
+function. These helper functions will start the transaction, execute a function,
+and then safely close your transaction if an error is returned. This is the
+recommended way to use Bolt transactions.
+
+However, sometimes you may want to manually start and end your transactions.
+You can use the `DB.Begin()` function directly but **please** be sure to close
+the transaction.
+
+```go
+// Start a writable transaction.
+tx, err := db.Begin(true)
+if err != nil {
+    return err
+}
+defer tx.Rollback()
+
+// Use the transaction...
+_, err := tx.CreateBucket([]byte("MyBucket"))
+if err != nil {
+    return err
+}
+
+// Commit the transaction and check for error.
+if err := tx.Commit(); err != nil {
+    return err
+}
+```
+
+The first argument to `DB.Begin()` is a boolean stating if the transaction
+should be writable.
+
+
+### Using buckets
+
+Buckets are collections of key/value pairs within the database. All keys in a
+bucket must be unique. You can create a bucket using the `Tx.CreateBucket()`
+function:
+
+```go
+db.Update(func(tx *bolt.Tx) error {
+	b, err := tx.CreateBucket([]byte("MyBucket"))
+	if err != nil {
+		return fmt.Errorf("create bucket: %s", err)
+	}
+	return nil
+})
+```
+
+You can also create a bucket only if it doesn't exist by using the
+`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this
+function for all your top-level buckets after you open your database so you can
+guarantee that they exist for future transactions.
+
+To delete a bucket, simply call the `Tx.DeleteBucket()` function.
+
+
+### Using key/value pairs
+
+To save a key/value pair to a bucket, use the `Bucket.Put()` function:
+
+```go
+db.Update(func(tx *bolt.Tx) error {
+	b := tx.Bucket([]byte("MyBucket"))
+	err := b.Put([]byte("answer"), []byte("42"))
+	return err
+})
+```
+
+This will set the value of the `"answer"` key to `"42"` in the `MyBucket`
+bucket. To retrieve this value, we can use the `Bucket.Get()` function:
+
+```go
+db.View(func(tx *bolt.Tx) error {
+	b := tx.Bucket([]byte("MyBucket"))
+	v := b.Get([]byte("answer"))
+	fmt.Printf("The answer is: %s\n", v)
+	return nil
+})
+```
+
+The `Get()` function does not return an error because its operation is
+guaranteed to work (unless there is some kind of system failure). If the key
+exists then it will return its byte slice value. If it doesn't exist then it
+will return `nil`. It's important to note that you can have a zero-length value
+set to a key which is different than the key not existing.
+
+Use the `Bucket.Delete()` function to delete a key from the bucket.
+
+Please note that values returned from `Get()` are only valid while the
+transaction is open. If you need to use a value outside of the transaction
+then you must use `copy()` to copy it to another byte slice.
+
+
+### Autoincrementing integer for the bucket
+By using the `NextSequence()` function, you can let Bolt determine a sequence
+which can be used as the unique identifier for your key/value pairs. See the
+example below.
+
+```go
+// CreateUser saves u to the store. The new user ID is set on u once the data is persisted.
+func (s *Store) CreateUser(u *User) error {
+    return s.db.Update(func(tx *bolt.Tx) error {
+        // Retrieve the users bucket.
+        // This should be created when the DB is first opened.
+        b := tx.Bucket([]byte("users"))
+
+        // Generate ID for the user.
+        // This returns an error only if the Tx is closed or not writeable.
+        // That can't happen in an Update() call so I ignore the error check.
+        id, _ := b.NextSequence()
+        u.ID = int(id)
+
+        // Marshal user data into bytes.
+        buf, err := json.Marshal(u)
+        if err != nil {
+            return err
+        }
+
+        // Persist bytes to users bucket.
+        return b.Put(itob(u.ID), buf)
+    })
+}
+
+// itob returns an 8-byte big endian representation of v.
+func itob(v int) []byte {
+    b := make([]byte, 8)
+    binary.BigEndian.PutUint64(b, uint64(v))
+    return b
+}
+
+type User struct {
+    ID int
+    ...
+}
+```
+
+### Iterating over keys
+
+Bolt stores its keys in byte-sorted order within a bucket. This makes sequential
+iteration over these keys extremely fast. To iterate over keys we'll use a
+`Cursor`:
+
+```go
+db.View(func(tx *bolt.Tx) error {
+	// Assume bucket exists and has keys
+	b := tx.Bucket([]byte("MyBucket"))
+
+	c := b.Cursor()
+
+	for k, v := c.First(); k != nil; k, v = c.Next() {
+		fmt.Printf("key=%s, value=%s\n", k, v)
+	}
+
+	return nil
+})
+```
+
+The cursor allows you to move to a specific point in the list of keys and move
+forward or backward through the keys one at a time.
+
+The following functions are available on the cursor:
+
+```
+First()  Move to the first key.
+Last()   Move to the last key.
+Seek()   Move to a specific key.
+Next()   Move to the next key.
+Prev()   Move to the previous key.
+```
+
+Each of those functions has a return signature of `(key []byte, value []byte)`.
+When you have iterated to the end of the cursor then `Next()` will return a
+`nil` key.  You must seek to a position using `First()`, `Last()`, or `Seek()`
+before calling `Next()` or `Prev()`. If you do not seek to a position then
+these functions will return a `nil` key.
+
+During iteration, if the key is non-`nil` but the value is `nil`, that means
+the key refers to a bucket rather than a value.  Use `Bucket.Bucket()` to
+access the sub-bucket.
+
+
+#### Prefix scans
+
+To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`:
+
+```go
+db.View(func(tx *bolt.Tx) error {
+	// Assume bucket exists and has keys
+	c := tx.Bucket([]byte("MyBucket")).Cursor()
+
+	prefix := []byte("1234")
+	for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() {
+		fmt.Printf("key=%s, value=%s\n", k, v)
+	}
+
+	return nil
+})
+```
+
+#### Range scans
+
+Another common use case is scanning over a range such as a time range. If you
+use a sortable time encoding such as RFC3339 then you can query a specific
+date range like this:
+
+```go
+db.View(func(tx *bolt.Tx) error {
+	// Assume our events bucket exists and has RFC3339 encoded time keys.
+	c := tx.Bucket([]byte("Events")).Cursor()
+
+	// Our time range spans the 90's decade.
+	min := []byte("1990-01-01T00:00:00Z")
+	max := []byte("2000-01-01T00:00:00Z")
+
+	// Iterate over the 90's.
+	for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() {
+		fmt.Printf("%s: %s\n", k, v)
+	}
+
+	return nil
+})
+```
+
+Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable.
+
+
+#### ForEach()
+
+You can also use the function `ForEach()` if you know you'll be iterating over
+all the keys in a bucket:
+
+```go
+db.View(func(tx *bolt.Tx) error {
+	// Assume bucket exists and has keys
+	b := tx.Bucket([]byte("MyBucket"))
+
+	b.ForEach(func(k, v []byte) error {
+		fmt.Printf("key=%s, value=%s\n", k, v)
+		return nil
+	})
+	return nil
+})
+```
+
+Please note that keys and values in `ForEach()` are only valid while
+the transaction is open. If you need to use a key or value outside of
+the transaction, you must use `copy()` to copy it to another byte
+slice.
+
+### Nested buckets
+
+You can also store a bucket in a key to create nested buckets. The API is the
+same as the bucket management API on the `DB` object:
+
+```go
+func (*Bucket) CreateBucket(key []byte) (*Bucket, error)
+func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error)
+func (*Bucket) DeleteBucket(key []byte) error
+```
+
+Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings.
+
+```go
+
+// createUser creates a new user in the given account.
+func createUser(accountID int, u *User) error {
+    // Start the transaction.
+    tx, err := db.Begin(true)
+    if err != nil {
+        return err
+    }
+    defer tx.Rollback()
+
+    // Retrieve the root bucket for the account.
+    // Assume this has already been created when the account was set up.
+    root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10)))
+
+    // Setup the users bucket.
+    bkt, err := root.CreateBucketIfNotExists([]byte("USERS"))
+    if err != nil {
+        return err
+    }
+
+    // Generate an ID for the new user.
+    userID, err := bkt.NextSequence()
+    if err != nil {
+        return err
+    }
+    u.ID = userID
+
+    // Marshal and save the encoded user.
+    if buf, err := json.Marshal(u); err != nil {
+        return err
+    } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil {
+        return err
+    }
+
+    // Commit the transaction.
+    if err := tx.Commit(); err != nil {
+        return err
+    }
+
+    return nil
+}
+
+```
+
+
+
+
+### Database backups
+
+Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()`
+function to write a consistent view of the database to a writer. If you call
+this from a read-only transaction, it will perform a hot backup and not block
+your other database reads and writes.
+
+By default, it will use a regular file handle which will utilize the operating
+system's page cache. See the [`Tx`](https://godoc.org/go.etcd.io/bbolt#Tx)
+documentation for information about optimizing for larger-than-RAM datasets.
+
+One common use case is to backup over HTTP so you can use tools like `cURL` to
+do database backups:
+
+```go
+func BackupHandleFunc(w http.ResponseWriter, req *http.Request) {
+	err := db.View(func(tx *bolt.Tx) error {
+		w.Header().Set("Content-Type", "application/octet-stream")
+		w.Header().Set("Content-Disposition", `attachment; filename="my.db"`)
+		w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size())))
+		_, err := tx.WriteTo(w)
+		return err
+	})
+	if err != nil {
+		http.Error(w, err.Error(), http.StatusInternalServerError)
+	}
+}
+```
+
+Then you can backup using this command:
+
+```sh
+$ curl http://localhost/backup > my.db
+```
+
+Or you can open your browser to `http://localhost/backup` and it will download
+automatically.
+
+If you want to backup to another file you can use the `Tx.CopyFile()` helper
+function.
+
+
+### Statistics
+
+The database keeps a running count of many of the internal operations it
+performs so you can better understand what's going on. By grabbing a snapshot
+of these stats at two points in time we can see what operations were performed
+in that time range.
+
+For example, we could start a goroutine to log stats every 10 seconds:
+
+```go
+go func() {
+	// Grab the initial stats.
+	prev := db.Stats()
+
+	for {
+		// Wait for 10s.
+		time.Sleep(10 * time.Second)
+
+		// Grab the current stats and diff them.
+		stats := db.Stats()
+		diff := stats.Sub(&prev)
+
+		// Encode stats to JSON and print to STDERR.
+		json.NewEncoder(os.Stderr).Encode(diff)
+
+		// Save stats for the next loop.
+		prev = stats
+	}
+}()
+```
+
+It's also useful to pipe these stats to a service such as statsd for monitoring
+or to provide an HTTP endpoint that will perform a fixed-length sample.
+
+
+### Read-Only Mode
+
+Sometimes it is useful to create a shared, read-only Bolt database. To this,
+set the `Options.ReadOnly` flag when opening your database. Read-only mode
+uses a shared lock to allow multiple processes to read from the database but
+it will block any processes from opening the database in read-write mode.
+
+```go
+db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true})
+if err != nil {
+	log.Fatal(err)
+}
+```
+
+### Mobile Use (iOS/Android)
+
+Bolt is able to run on mobile devices by leveraging the binding feature of the
+[gomobile](https://github.com/golang/mobile) tool. Create a struct that will
+contain your database logic and a reference to a `*bolt.DB` with a initializing
+constructor that takes in a filepath where the database file will be stored.
+Neither Android nor iOS require extra permissions or cleanup from using this method.
+
+```go
+func NewBoltDB(filepath string) *BoltDB {
+	db, err := bolt.Open(filepath+"/demo.db", 0600, nil)
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	return &BoltDB{db}
+}
+
+type BoltDB struct {
+	db *bolt.DB
+	...
+}
+
+func (b *BoltDB) Path() string {
+	return b.db.Path()
+}
+
+func (b *BoltDB) Close() {
+	b.db.Close()
+}
+```
+
+Database logic should be defined as methods on this wrapper struct.
+
+To initialize this struct from the native language (both platforms now sync
+their local storage to the cloud. These snippets disable that functionality for the
+database file):
+
+#### Android
+
+```java
+String path;
+if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){
+    path = getNoBackupFilesDir().getAbsolutePath();
+} else{
+    path = getFilesDir().getAbsolutePath();
+}
+Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path)
+```
+
+#### iOS
+
+```objc
+- (void)demo {
+    NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
+                                                          NSUserDomainMask,
+                                                          YES) objectAtIndex:0];
+	GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path);
+	[self addSkipBackupAttributeToItemAtPath:demo.path];
+	//Some DB Logic would go here
+	[demo close];
+}
+
+- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString
+{
+    NSURL* URL= [NSURL fileURLWithPath: filePathString];
+    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);
+
+    NSError *error = nil;
+    BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
+                                  forKey: NSURLIsExcludedFromBackupKey error: &error];
+    if(!success){
+        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
+    }
+    return success;
+}
+
+```

+
+## Comparison with other databases
+
+### Postgres, MySQL, & other relational databases
+
+Relational databases structure data into rows and are only accessible through
+the use of SQL. This approach provides flexibility in how you store and query
+your data but also incurs overhead in parsing and planning SQL statements. Bolt
+accesses all data by a byte slice key. This makes Bolt fast to read and write
+data by key but provides no built-in support for joining values together.
+
+Most relational databases (with the exception of SQLite) are standalone servers
+that run separately from your application. This gives your systems
+flexibility to connect multiple application servers to a single database
+server but also adds overhead in serializing and transporting data over the
+network. Bolt runs as a library included in your application so all data access
+has to go through your application's process. This brings data closer to your
+application but limits multi-process access to the data.
+
+
+### LevelDB, RocksDB
+
+LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that
+they are libraries bundled into the application, however, their underlying
+structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes
+random writes by using a write ahead log and multi-tiered, sorted files called
+SSTables. Bolt uses a B+tree internally and only a single file. Both approaches
+have trade-offs.
+
+If you require a high random write throughput (>10,000 w/sec) or you need to use
+spinning disks then LevelDB could be a good choice. If your application is
+read-heavy or does a lot of range scans then Bolt could be a good choice.
+
+One other important consideration is that LevelDB does not have transactions.
+It supports batch writing of key/values pairs and it supports read snapshots
+but it will not give you the ability to do a compare-and-swap operation safely.
+Bolt supports fully serializable ACID transactions.
+
+
+### LMDB
+
+Bolt was originally a port of LMDB so it is architecturally similar. Both use
+a B+tree, have ACID semantics with fully serializable transactions, and support
+lock-free MVCC using a single writer and multiple readers.
+
+The two projects have somewhat diverged. LMDB heavily focuses on raw performance
+while Bolt has focused on simplicity and ease of use. For example, LMDB allows
+several unsafe actions such as direct writes for the sake of performance. Bolt
+opts to disallow actions which can leave the database in a corrupted state. The
+only exception to this in Bolt is `DB.NoSync`.
+
+There are also a few differences in API. LMDB requires a maximum mmap size when
+opening an `mdb_env` whereas Bolt will handle incremental mmap resizing
+automatically. LMDB overloads the getter and setter functions with multiple
+flags whereas Bolt splits these specialized cases into their own functions.
+
+
+## Caveats & Limitations
+
+It's important to pick the right tool for the job and Bolt is no exception.
+Here are a few things to note when evaluating and using Bolt:
+
+* Bolt is good for read intensive workloads. Sequential write performance is
+  also fast but random writes can be slow. You can use `DB.Batch()` or add a
+  write-ahead log to help mitigate this issue.
+
+* Bolt uses a B+tree internally so there can be a lot of random page access.
+  SSDs provide a significant performance boost over spinning disks.
+
+* Try to avoid long running read transactions. Bolt uses copy-on-write so
+  old pages cannot be reclaimed while an old transaction is using them.
+
+* Byte slices returned from Bolt are only valid during a transaction. Once the
+  transaction has been committed or rolled back then the memory they point to
+  can be reused by a new page or can be unmapped from virtual memory and you'll
+  see an `unexpected fault address` panic when accessing it.
+
+* Bolt uses an exclusive write lock on the database file so it cannot be
+  shared by multiple processes.
+
+* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for
+  buckets that have random inserts will cause your database to have very poor
+  page utilization.
+
+* Use larger buckets in general. Smaller buckets causes poor page utilization
+  once they become larger than the page size (typically 4KB).
+
+* Bulk loading a lot of random writes into a new bucket can be slow as the
+  page will not split until the transaction is committed. Randomly inserting
+  more than 100,000 key/value pairs into a single new bucket in a single
+  transaction is not advised.
+
+* Bolt uses a memory-mapped file so the underlying operating system handles the
+  caching of the data. Typically, the OS will cache as much of the file as it
+  can in memory and will release memory as needed to other processes. This means
+  that Bolt can show very high memory usage when working with large databases.
+  However, this is expected and the OS will release memory as needed. Bolt can
+  handle databases much larger than the available physical RAM, provided its
+  memory-map fits in the process virtual address space. It may be problematic
+  on 32-bits systems.
+
+* The data structures in the Bolt database are memory mapped so the data file
+  will be endian specific. This means that you cannot copy a Bolt file from a
+  little endian machine to a big endian machine and have it work. For most
+  users this is not a concern since most modern CPUs are little endian.
+
+* Because of the way pages are laid out on disk, Bolt cannot truncate data files
+  and return free pages back to the disk. Instead, Bolt maintains a free list
+  of unused pages within its data file. These free pages can be reused by later
+  transactions. This works well for many use cases as databases generally tend
+  to grow. However, it's important to note that deleting large chunks of data
+  will not allow you to reclaim that space on disk.
+

+
+
+## Reading the Source
+
+Bolt is a relatively small code base (<5KLOC) for an embedded, serializable,
+transactional key/value database so it can be a good starting point for people
+interested in how databases work.
+
+The best places to start are the main entry points into Bolt:
+
+- `Open()` - Initializes the reference to the database. It's responsible for
+  creating the database if it doesn't exist, obtaining an exclusive lock on the
+  file, reading the meta pages, & memory-mapping the file.
+
+- `DB.Begin()` - Starts a read-only or read-write transaction depending on the
+  value of the `writable` argument. This requires briefly obtaining the "meta"
+  lock to keep track of open transactions. Only one read-write transaction can
+  exist at a time so the "rwlock" is acquired during the life of a read-write
+  transaction.
+
+- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the
+  arguments, a cursor is used to traverse the B+tree to the page and position
+  where they key & value will be written. Once the position is found, the bucket
+  materializes the underlying page and the page's parent pages into memory as
+  "nodes". These nodes are where mutations occur during read-write transactions.
+  These changes get flushed to disk during commit.
+
+- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor
+  to move to the page & position of a key/value pair. During a read-only
+  transaction, the key and value data is returned as a direct reference to the
+  underlying mmap file so there's no allocation overhead. For read-write
+  transactions, this data may reference the mmap file or one of the in-memory
+  node values.
+
+- `Cursor` - This object is simply for traversing the B+tree of on-disk pages
+  or in-memory nodes. It can seek to a specific key, move to the first or last
+  value, or it can move forward or backward. The cursor handles the movement up
+  and down the B+tree transparently to the end user.
+
+- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages
+  into pages to be written to disk. Writing to disk then occurs in two phases.
+  First, the dirty pages are written to disk and an `fsync()` occurs. Second, a
+  new meta page with an incremented transaction ID is written and another
+  `fsync()` occurs. This two phase write ensures that partially written data
+  pages are ignored in the event of a crash since the meta page pointing to them
+  is never written. Partially written meta pages are invalidated because they
+  are written with a checksum.

+/*
+package bbolt implements a low-level key/value store in pure Go. It supports
+fully serializable transactions, ACID semantics, and lock-free MVCC with
+multiple readers and a single writer. Bolt can be used for projects that
+want a simple data store without the need to add large dependencies such as
+Postgres or MySQL.
+
+Bolt is a single-level, zero-copy, B+tree data store. This means that Bolt is
+optimized for fast read access and does not require recovery in the event of a
+system crash. Transactions which have not finished committing will simply be
+rolled back in the event of a crash.
+
+The design of Bolt is based on Howard Chu's LMDB database project.
+
+Bolt currently works on Windows, Mac OS X, and Linux.
+
+
+Basics
+
+There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is
+a collection of buckets and is represented by a single file on disk. A bucket is
+a collection of unique keys that are associated with values.
+
+Transactions provide either read-only or read-write access to the database.
+Read-only transactions can retrieve key/value pairs and can use Cursors to
+iterate over the dataset sequentially. Read-write transactions can create and
+delete buckets and can insert and remove keys. Only one read-write transaction
+is allowed at a time.
+
+
+Caveats
+
+The database uses a read-only, memory-mapped data file to ensure that
+applications cannot corrupt the database, however, this means that keys and
+values returned from Bolt cannot be changed. Writing to a read-only byte slice
+will cause Go to panic.
+
+Keys and values retrieved from the database are only valid for the life of
+the transaction. When used outside the transaction, these byte slices can
+point to different data or can point to invalid memory which will cause a panic.
+

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# etcd/client
+
+etcd/client is the Go client library for etcd.
+
+[![GoDoc](https://godoc.org/github.com/coreos/etcd/client?status.png)](https://godoc.org/github.com/coreos/etcd/client)
+
+etcd uses `cmd/vendor` directory to store external dependencies, which are
+to be compiled into etcd release binaries. `client` can be imported without
+vendoring. For full compatibility, it is recommended to vendor builds using
+etcd's vendored packages, using tools like godep, as in
+[vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
+For more detail, please read [Go vendor design](https://golang.org/s/go15vendor).
+
+## Install
+
+```bash
+go get github.com/coreos/etcd/client
+```
+
+## Usage
+
+```go
+package main
+
+import (
+	"log"
+	"time"
+	"context"
+
+	"github.com/coreos/etcd/client"
+)
+
+func main() {
+	cfg := client.Config{
+		Endpoints:               []string{"http://127.0.0.1:2379"},
+		Transport:               client.DefaultTransport,
+		// set timeout per request to fail fast when the target endpoint is unavailable
+		HeaderTimeoutPerRequest: time.Second,
+	}
+	c, err := client.New(cfg)
+	if err != nil {
+		log.Fatal(err)
+	}
+	kapi := client.NewKeysAPI(c)
+	// set "/foo" key with "bar" value
+	log.Print("Setting '/foo' key with 'bar' value")
+	resp, err := kapi.Set(context.Background(), "/foo", "bar", nil)
+	if err != nil {
+		log.Fatal(err)
+	} else {
+		// print common key info
+		log.Printf("Set is done. Metadata is %q\n", resp)
+	}
+	// get "/foo" key's value
+	log.Print("Getting '/foo' key value")
+	resp, err = kapi.Get(context.Background(), "/foo", nil)
+	if err != nil {
+		log.Fatal(err)
+	} else {
+		// print common key info
+		log.Printf("Get is done. Metadata is %q\n", resp)
+		// print value
+		log.Printf("%q key has %q value\n", resp.Node.Key, resp.Node.Value)
+	}
+}
+```
+
+## Error Handling
+
+etcd client might return three types of errors.
+
+- context error
+
+Each API call has its first parameter as `context`. A context can be canceled or have an attached deadline. If the context is canceled or reaches its deadline, the responding context error will be returned no matter what internal errors the API call has already encountered.
+
+- cluster error
+
+Each API call tries to send request to the cluster endpoints one by one until it successfully gets a response. If a requests to an endpoint fails, due to exceeding per request timeout or connection issues, the error will be added into a list of errors. If all possible endpoints fail, a cluster error that includes all encountered errors will be returned.
+
+- response error
+
+If the response gets from the cluster is invalid, a plain string error will be returned. For example, it might be a invalid JSON error.
+
+Here is the example code to handle client errors:
+
+```go
+cfg := client.Config{Endpoints: []string{"http://etcd1:2379","http://etcd2:2379","http://etcd3:2379"}}
+c, err := client.New(cfg)
+if err != nil {
+	log.Fatal(err)
+}
+
+kapi := client.NewKeysAPI(c)
+resp, err := kapi.Set(ctx, "test", "bar", nil)
+if err != nil {
+	if err == context.Canceled {
+		// ctx is canceled by another routine
+	} else if err == context.DeadlineExceeded {
+		// ctx is attached with a deadline and it exceeded
+	} else if cerr, ok := err.(*client.ClusterError); ok {
+		// process (cerr.Errors)
+	} else {
+		// bad cluster endpoints, which are not etcd servers
+	}
+}
+```
+
+
+## Caveat
+
+1. etcd/client prefers to use the same endpoint as long as the endpoint continues to work well. This saves socket resources, and improves efficiency for both client and server side. This preference doesn't remove consistency from the data consumed by the client because data replicated to each etcd member has already passed through the consensus process.
+
+2. etcd/client does round-robin rotation on other available endpoints if the preferred endpoint isn't functioning properly. For example, if the member that etcd/client connects to is hard killed, etcd/client will fail on the first attempt with the killed member, and succeed on the second attempt with another member. If it fails to talk to all available endpoints, it will return all errors happened.
+
+3. Default etcd/client cannot handle the case that the remote server is SIGSTOPed now. TCP keepalive mechanism doesn't help in this scenario because operating system may still send TCP keep-alive packets. Over time we'd like to improve this functionality, but solving this issue isn't high priority because a real-life case in which a server is stopped, but the connection is kept alive, hasn't been brought to our attention.
+
+4. etcd/client cannot detect whether a member is healthy with watches and non-quorum read requests. If the member is isolated from the cluster, etcd/client may retrieve outdated data. Instead, users can either issue quorum read requests or monitor the /health endpoint for member health information.

+// Our implementation hinges around a powerful primitive which we call MultiOp. All other database

+// and consists of three components:
+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.
+// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.

+## Red-Black Tree
+
+*"Introduction to Algorithms" (Cormen et al, 3rd ed.), Chapter 13*
+
+1. Every node is either red or black.
+2. The root is black.
+3. Every leaf (NIL) is black.
+4. If a node is red, then both its children are black.
+5. For each node, all simple paths from the node to descendant leaves contain the
+same number of black nodes.
+
+For example,
+
+```go
+import (
+    "fmt"
+
+    "go.etcd.io/etcd/pkg/adt"
+)
+
+func main() {
+    ivt := adt.NewIntervalTree()
+    ivt.Insert(NewInt64Interval(510, 511), 0)
+    ivt.Insert(NewInt64Interval(82, 83), 0)
+    ivt.Insert(NewInt64Interval(830, 831), 0)
+    ...
+```
+
+After inserting the values `510`, `82`, `830`, `11`, `383`, `647`, `899`, `261`, `410`, `514`, `815`, `888`, `972`, `238`, `292`, `953`.
+
+![red-black-tree-01-insertion.png](img/red-black-tree-01-insertion.png)
+
+Deleting the node `514` should not trigger any rebalancing:
+
+![red-black-tree-02-delete-514.png](img/red-black-tree-02-delete-514.png)
+
+Deleting the node `11` triggers multiple rotates for rebalancing:
+
+![red-black-tree-03-delete-11.png](img/red-black-tree-03-delete-11.png)
+![red-black-tree-04-delete-11.png](img/red-black-tree-04-delete-11.png)

+# Raft library
+
+Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
+The state machine is kept in sync through the use of a replicated log.
+For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
+(https://ramcloud.stanford.edu/raft.pdf) by Diego Ongaro and John Ousterhout.
+
+This Raft library is stable and feature complete. As of 2016, it is **the most widely used** Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, and more.
+
+Most Raft implementations have a monolithic design, including storage handling, messaging serialization, and network transport. This library instead follows a minimalistic design philosophy by only implementing the core raft algorithm. This minimalism buys flexibility, determinism, and performance.
+
+To keep the codebase small as well as provide flexibility, the library only implements the Raft algorithm; both network and disk IO are left to the user. Library users must implement their own transportation layer for message passing between Raft peers over the wire. Similarly, users must implement their own storage layer to persist the Raft log and state.
+
+In order to easily test the Raft library, its behavior should be deterministic. To achieve this determinism, the library models Raft as a state machine.  The state machine takes a `Message` as input. A message can either be a local timer update or a network message sent from a remote peer. The state machine's output is a 3-tuple `{[]Messages, []LogEntries, NextState}` consisting of an array of `Messages`, `log entries`, and `Raft state changes`. For state machines with the same state, the same state machine input should always generate the same state machine output.
+
+A simple example application, _raftexample_, is also available to help illustrate how to use this package in practice: https://github.com/coreos/etcd/tree/master/contrib/raftexample
+
+# Features
+
+This raft implementation is a full feature implementation of Raft protocol. Features includes:
+
+- Leader election
+- Log replication
+- Log compaction 
+- Membership changes
+- Leadership transfer extension
+- Efficient linearizable read-only queries served by both the leader and followers
+  - leader checks with quorum and bypasses Raft log before processing read-only queries
+  - followers asks leader to get a safe read index before processing read-only queries
+- More efficient lease-based linearizable read-only queries served by both the leader and followers
+  - leader bypasses Raft log and processing read-only queries locally
+  - followers asks leader to get a safe read index before processing read-only queries
+  - this approach relies on the clock of the all the machines in raft group
+
+This raft implementation also includes a few optional enhancements:
+
+- Optimistic pipelining to reduce log replication latency
+- Flow control for log replication
+- Batching Raft messages to reduce synchronized network I/O calls
+- Batching log entries to reduce disk synchronized I/O
+- Writing to leader's disk in parallel
+- Internal proposal redirection from followers to leader
+- Automatic stepping down when the leader loses quorum

+
+## Usage
+
+The primary object in raft is a Node. Either start a Node from scratch using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a three-node cluster
+```go
+  storage := raft.NewMemoryStorage()
+  c := &Config{
+    ID:              0x01,
+    ElectionTick:    10,
+    HeartbeatTick:   1,
+    Storage:         storage,
+    MaxSizePerMsg:   4096,
+    MaxInflightMsgs: 256,
+  }
+  // Set peer list to the other nodes in the cluster.
+  // Note that they need to be started separately as well.
+  n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+```
+
+Start a single node cluster, like so:
+```go
+  // Create storage and config as shown above.
+  // Set peer list to itself, so this node can become the leader of this single-node cluster.
+  peers := []raft.Peer{{ID: 0x01}}
+  n := raft.StartNode(c, peers)
+```
+
+To allow a new node to join this cluster, do not pass in any peers. First, add the node to the existing cluster by calling `ProposeConfChange` on any existing node inside the cluster. Then, start the node with an empty peer list, like so:
+```go
+  // Create storage and config as shown above.
+  n := raft.StartNode(c, nil)
+```
+
+To restart a node from previous state:
+```go
+  storage := raft.NewMemoryStorage()
+
+  // Recover the in-memory storage from persistent snapshot, state and entries.
+  storage.ApplySnapshot(snapshot)
+  storage.SetHardState(state)
+  storage.Append(entries)
+
+  c := &Config{
+    ID:              0x01,
+    ElectionTick:    10,
+    HeartbeatTick:   1,
+    Storage:         storage,
+    MaxSizePerMsg:   4096,
+    MaxInflightMsgs: 256,
+  }
+
+  // Restart raft without peer information.
+  // Peer information is already included in the storage.
+  n := raft.RestartNode(c)
+```
+
+After creating a Node, the user has a few responsibilities:
+
+First, read from the Node.Ready() channel and process the updates it contains. These steps may be performed in parallel, except as noted in step 2.
+
+1. Write Entries, HardState and Snapshot to persistent storage in order, i.e. Entries first, then HardState and Snapshot if they are not empty. If persistent storage supports atomic writes then all of them can be written together. Note that when writing an Entry with Index i, any previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that no messages be sent until the latest HardState has been persisted to disk, and all Entries written by any previous Ready batch (Messages may be sent while entries from the same batch are being persisted). To reduce the I/O latency, an optimization can be applied to make leader write to disk in parallel with its followers (as explained at section 10.2.1 in Raft thesis). If any Message has type MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be large). Note: Marshalling messages is not thread-safe; it is important to make sure that no new entries are persisted while marshalling. The easiest way to achieve this is to serialise the messages directly inside the main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine. If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() to apply it to the node. The configuration change may be cancelled at this point by setting the NodeID field to zero before calling ApplyConfChange (but ApplyConfChange must be called one way or the other, and the decision to cancel must be based solely on the state machine and not external information such as the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates. This may be done at any time after step 1, although all updates must be processed in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an implementation of the Storage interface. The provided MemoryStorage type can be used for this (if repopulating its state upon a restart), or a custom disk-backed implementation can be supplied.
+
+Third, after receiving a message from another node, pass it to Node.Step:
+
+```go
+	func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+		n.Step(ctx, m)
+	}
+```
+
+Finally, call `Node.Tick()` at regular intervals (probably via a `time.Ticker`). Raft has two important timeouts: heartbeat and the election timeout. However, internally to the raft package time is represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+```go
+  for {
+    select {
+    case <-s.Ticker:
+      n.Tick()
+    case rd := <-s.Node.Ready():
+      saveToStorage(rd.State, rd.Entries, rd.Snapshot)
+      send(rd.Messages)
+      if !raft.IsEmptySnap(rd.Snapshot) {
+        processSnapshot(rd.Snapshot)
+      }
+      for _, entry := range rd.CommittedEntries {
+        process(entry)
+        if entry.Type == raftpb.EntryConfChange {
+          var cc raftpb.ConfChange
+          cc.Unmarshal(entry.Data)
+          s.Node.ApplyConfChange(cc)
+        }
+      }
+      s.Node.Advance()
+    case <-s.done:
+      return
+    }
+  }
+```
+
+To propose changes to the state machine from the node to take application data, serialize it into a byte slice and call:
+
+```go
+	n.Propose(ctx, data)
+```
+
+If the proposal is committed, data will appear in committed entries with type raftpb.EntryNormal. There is no guarantee that a proposed command will be committed; the command may have to be reproposed after a timeout. 
+
+To add or remove node in a cluster, build ConfChange struct 'cc' and call:
+
+```go
+	n.ProposeConfChange(ctx, cc)
+```
+
+After config change is committed, some committed entry with type raftpb.EntryConfChange will be returned. This must be applied to node through:
+
+```go
+	var cc raftpb.ConfChange
+	cc.Unmarshal(data)
+	n.ApplyConfChange(cc)
+```
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+## Implementation notes
+
+This implementation is up to date with the final Raft thesis (https://ramcloud.stanford.edu/~ongaro/thesis.pdf), although this implementation of the membership change protocol differs somewhat from that described in chapter 4. The key invariant that membership changes happen one node at a time is preserved, but in our implementation the membership change takes effect when its entry is applied, not when it is added to the log (so the entry is committed under the old membership instead of the new). This is equivalent in terms of safety, since the old and new configurations are guaranteed to overlap.
+
+To ensure there is no attempt to commit two membership changes at once by matching log positions (which would be unsafe since they should have different quorum requirements), any proposed membership change is simply disallowed while any uncommitted change appears in the leader's log.
+
+This approach introduces a problem when removing a member from a two-member cluster: If one of the members dies before the other one receives the commit of the confchange entry, then the member cannot be removed any more since the cluster cannot make progress. For this reason it is highly recommended to use three or more nodes in every cluster.

+## Progress
+
+Progress represents a follower’s progress in the view of the leader. Leader maintains progresses of all followers, and sends `replication message` to the follower based on its progress. 
+
+`replication message` is a `msgApp` with log entries.
+
+A progress has two attribute: `match` and `next`. `match` is the index of the highest known matched entry. If leader knows nothing about follower’s replication status, `match` is set to zero. `next` is the index of the first entry that will be replicated to the follower. Leader puts entries from `next` to its latest one in next `replication message`.
+
+A progress is in one of the three state: `probe`, `replicate`, `snapshot`. 
+

+
+When the progress of a follower is in `probe` state, leader sends at most one `replication message` per heartbeat interval. The leader sends `replication message` slowly and probing the actual progress of the follower. A `msgHeartbeatResp` or a `msgAppResp` with reject might trigger the sending of the next `replication message`.
+
+When the progress of a follower is in `replicate` state, leader sends `replication message`, then optimistically increases `next` to the latest entry sent. This is an optimized state for fast replicating log entries to the follower.
+
+When the progress of a follower is in `snapshot` state, leader stops sending any `replication message`.
+
+A newly elected leader sets the progresses of all the followers to `probe` state with `match` = 0 and `next` = last index. The leader slowly (at most once per heartbeat) sends `replication message` to the follower and probes its progress.
+
+A progress changes to `replicate` when the follower replies with a non-rejection `msgAppResp`, which implies that it has matched the index sent. At this point, leader starts to stream log entries to the follower fast. The progress will fall back to `probe` when the follower replies a rejection `msgAppResp` or the link layer reports the follower is unreachable. We aggressively reset `next` to `match`+1 since if we receive any `msgAppResp` soon, both `match` and `next` will increase directly to the `index` in `msgAppResp`. (We might end up with sending some duplicate entries when aggressively reset `next` too low.  see open question)
+
+A progress changes from `probe` to `snapshot` when the follower falls very far behind and requires a snapshot. After sending `msgSnap`, the leader waits until the success, failure or abortion of the previous snapshot sent. The progress will go back to `probe` after the sending result is applied.
+
+### Flow Control
+
+1. limit the max size of message sent per message. Max should be configurable.
+Lower the cost at probing state as we limit the size per message; lower the penalty when aggressively decreased to a too low `next`
+
+2. limit the # of in flight messages < N when in `replicate` state. N should be configurable. Most implementation will have a sending buffer on top of its actual network transport layer (not blocking raft node). We want to make sure raft does not overflow that buffer, which can cause message dropping and triggering a bunch of unnecessary resending repeatedly.

+Package raft sends and receives messages in the Protocol Buffer format
+defined in the raftpb package.
+
+Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
+The state machine is kept in sync through the use of a replicated log.
+For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
+(https://ramcloud.stanford.edu/raft.pdf) by Diego Ongaro and John Ousterhout.
+
+A simple example application, _raftexample_, is also available to help illustrate
+how to use this package in practice:
+https://github.com/coreos/etcd/tree/master/contrib/raftexample
+
+Usage
+
+The primary object in raft is a Node. You either start a Node from scratch
+using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a node from scratch:
+
+  storage := raft.NewMemoryStorage()
+  c := &Config{
+    ID:              0x01,
+    ElectionTick:    10,
+    HeartbeatTick:   1,
+    Storage:         storage,
+    MaxSizePerMsg:   4096,
+    MaxInflightMsgs: 256,
+  }
+  n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+
+To restart a node from previous state:
+
+  storage := raft.NewMemoryStorage()
+
+  // recover the in-memory storage from persistent
+  // snapshot, state and entries.
+  storage.ApplySnapshot(snapshot)
+  storage.SetHardState(state)
+  storage.Append(entries)
+
+  c := &Config{
+    ID:              0x01,
+    ElectionTick:    10,
+    HeartbeatTick:   1,
+    Storage:         storage,
+    MaxSizePerMsg:   4096,
+    MaxInflightMsgs: 256,
+  }
+
+  // restart raft without peer information.
+  // peer information is already included in the storage.
+  n := raft.RestartNode(c)
+
+Now that you are holding onto a Node you have a few responsibilities:
+
+First, you must read from the Node.Ready() channel and process the updates
+it contains. These steps may be performed in parallel, except as noted in step
+2.
+
+1. Write HardState, Entries, and Snapshot to persistent storage if they are
+not empty. Note that when writing an Entry with Index i, any
+previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that
+no messages be sent until the latest HardState has been persisted to disk,
+and all Entries written by any previous Ready batch (Messages may be sent while
+entries from the same batch are being persisted). To reduce the I/O latency, an
+optimization can be applied to make leader write to disk in parallel with its
+followers (as explained at section 10.2.1 in Raft thesis). If any Message has type
+MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be
+large).
+
+Note: Marshalling messages is not thread-safe; it is important that you
+make sure that no new entries are persisted while marshalling.
+The easiest way to achieve this is to serialise the messages directly inside
+your main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine.
+If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange()
+to apply it to the node. The configuration change may be cancelled at this point
+by setting the NodeID field to zero before calling ApplyConfChange
+(but ApplyConfChange must be called one way or the other, and the decision to cancel
+must be based solely on the state machine and not external information such as
+the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates.
+This may be done at any time after step 1, although all updates must be processed
+in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an
+implementation of the Storage interface. The provided MemoryStorage
+type can be used for this (if you repopulate its state upon a
+restart), or you can supply your own disk-backed implementation.
+
+Third, when you receive a message from another node, pass it to Node.Step:
+
+	func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+		n.Step(ctx, m)
+	}
+
+Finally, you need to call Node.Tick() at regular intervals (probably
+via a time.Ticker). Raft has two important timeouts: heartbeat and the
+election timeout. However, internally to the raft package time is
+represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+  for {
+    select {
+    case <-s.Ticker:
+      n.Tick()
+    case rd := <-s.Node.Ready():
+      saveToStorage(rd.State, rd.Entries, rd.Snapshot)
+      send(rd.Messages)
+      if !raft.IsEmptySnap(rd.Snapshot) {
+        processSnapshot(rd.Snapshot)
+      }
+      for _, entry := range rd.CommittedEntries {
+        process(entry)
+        if entry.Type == raftpb.EntryConfChange {
+          var cc raftpb.ConfChange
+          cc.Unmarshal(entry.Data)
+          s.Node.ApplyConfChange(cc)
+        }
+      }
+      s.Node.Advance()
+    case <-s.done:
+      return
+    }
+  }
+
+To propose changes to the state machine from your node take your application
+data, serialize it into a byte slice and call:
+
+	n.Propose(ctx, data)
+
+If the proposal is committed, data will appear in committed entries with type
+raftpb.EntryNormal. There is no guarantee that a proposed command will be
+committed; you may have to re-propose after a timeout.
+
+To add or remove node in a cluster, build ConfChange struct 'cc' and call:
+
+	n.ProposeConfChange(ctx, cc)
+
+After config change is committed, some committed entry with type
+raftpb.EntryConfChange will be returned. You must apply it to node through:
+
+	var cc raftpb.ConfChange
+	cc.Unmarshal(data)
+	n.ApplyConfChange(cc)
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+Implementation notes
+
+This implementation is up to date with the final Raft thesis
+(https://ramcloud.stanford.edu/~ongaro/thesis.pdf), although our
+implementation of the membership change protocol differs somewhat from
+that described in chapter 4. The key invariant that membership changes
+happen one node at a time is preserved, but in our implementation the
+membership change takes effect when its entry is applied, not when it
+is added to the log (so the entry is committed under the old
+membership instead of the new). This is equivalent in terms of safety,
+since the old and new configurations are guaranteed to overlap.
+
+To ensure that we do not attempt to commit two membership changes at
+once by matching log positions (which would be unsafe since they
+should have different quorum requirements), we simply disallow any
+proposed membership change while any uncommitted change appears in
+the leader's log.
+
+This approach introduces a problem when you try to remove a member
+from a two-member cluster: If one of the members dies before the
+other one receives the commit of the confchange entry, then the member
+cannot be removed any more since the cluster cannot make progress.
+For this reason it is highly recommended to use three or more nodes in
+every cluster.
+
+MessageType
+
+Package raft sends and receives message in Protocol Buffer format (defined
+in raftpb package). Each state (follower, candidate, leader) implements its
+own 'step' method ('stepFollower', 'stepCandidate', 'stepLeader') when
+advancing with the given raftpb.Message. Each step is determined by its
+raftpb.MessageType. Note that every step is checked by one common method
+'Step' that safety-checks the terms of node and incoming message to prevent
+stale log entries:
+
+	'MsgHup' is used for election. If a node is a follower or candidate, the
+	'tick' function in 'raft' struct is set as 'tickElection'. If a follower or
+	candidate has not received any heartbeat before the election timeout, it
+	passes 'MsgHup' to its Step method and becomes (or remains) a candidate to
+	start a new election.
+
+	'MsgBeat' is an internal type that signals the leader to send a heartbeat of
+	the 'MsgHeartbeat' type. If a node is a leader, the 'tick' function in
+	the 'raft' struct is set as 'tickHeartbeat', and triggers the leader to
+	send periodic 'MsgHeartbeat' messages to its followers.
+
+	'MsgProp' proposes to append data to its log entries. This is a special
+	type to redirect proposals to leader. Therefore, send method overwrites
+	raftpb.Message's term with its HardState's term to avoid attaching its
+	local term to 'MsgProp'. When 'MsgProp' is passed to the leader's 'Step'
+	method, the leader first calls the 'appendEntry' method to append entries
+	to its log, and then calls 'bcastAppend' method to send those entries to
+	its peers. When passed to candidate, 'MsgProp' is dropped. When passed to
+	follower, 'MsgProp' is stored in follower's mailbox(msgs) by the send
+	method. It is stored with sender's ID and later forwarded to leader by
+	rafthttp package.
+
+	'MsgApp' contains log entries to replicate. A leader calls bcastAppend,
+	which calls sendAppend, which sends soon-to-be-replicated logs in 'MsgApp'
+	type. When 'MsgApp' is passed to candidate's Step method, candidate reverts
+	back to follower, because it indicates that there is a valid leader sending
+	'MsgApp' messages. Candidate and follower respond to this message in
+	'MsgAppResp' type.
+
+	'MsgAppResp' is response to log replication request('MsgApp'). When
+	'MsgApp' is passed to candidate or follower's Step method, it responds by
+	calling 'handleAppendEntries' method, which sends 'MsgAppResp' to raft
+	mailbox.
+
+	'MsgVote' requests votes for election. When a node is a follower or
+	candidate and 'MsgHup' is passed to its Step method, then the node calls
+	'campaign' method to campaign itself to become a leader. Once 'campaign'
+	method is called, the node becomes candidate and sends 'MsgVote' to peers
+	in cluster to request votes. When passed to leader or candidate's Step
+	method and the message's Term is lower than leader's or candidate's,
+	'MsgVote' will be rejected ('MsgVoteResp' is returned with Reject true).
+	If leader or candidate receives 'MsgVote' with higher term, it will revert
+	back to follower. When 'MsgVote' is passed to follower, it votes for the
+	sender only when sender's last term is greater than MsgVote's term or
+	sender's last term is equal to MsgVote's term but sender's last committed
+	index is greater than or equal to follower's.
+
+	'MsgVoteResp' contains responses from voting request. When 'MsgVoteResp' is
+	passed to candidate, the candidate calculates how many votes it has won. If
+	it's more than majority (quorum), it becomes leader and calls 'bcastAppend'.
+	If candidate receives majority of votes of denials, it reverts back to
+	follower.
+
+	'MsgPreVote' and 'MsgPreVoteResp' are used in an optional two-phase election
+	protocol. When Config.PreVote is true, a pre-election is carried out first
+	(using the same rules as a regular election), and no node increases its term
+	number unless the pre-election indicates that the campaigining node would win.
+	This minimizes disruption when a partitioned node rejoins the cluster.
+
+	'MsgSnap' requests to install a snapshot message. When a node has just
+	become a leader or the leader receives 'MsgProp' message, it calls
+	'bcastAppend' method, which then calls 'sendAppend' method to each
+	follower. In 'sendAppend', if a leader fails to get term or entries,
+	the leader requests snapshot by sending 'MsgSnap' type message.
+
+	'MsgSnapStatus' tells the result of snapshot install message. When a
+	follower rejected 'MsgSnap', it indicates the snapshot request with
+	'MsgSnap' had failed from network issues which causes the network layer
+	to fail to send out snapshots to its followers. Then leader considers
+	follower's progress as probe. When 'MsgSnap' were not rejected, it
+	indicates that the snapshot succeeded and the leader sets follower's
+	progress to probe and resumes its log replication.
+
+	'MsgHeartbeat' sends heartbeat from leader. When 'MsgHeartbeat' is passed
+	to candidate and message's term is higher than candidate's, the candidate
+	reverts back to follower and updates its committed index from the one in
+	this heartbeat. And it sends the message to its mailbox. When
+	'MsgHeartbeat' is passed to follower's Step method and message's term is
+	higher than follower's, the follower updates its leaderID with the ID
+	from the message.
+
+	'MsgHeartbeatResp' is a response to 'MsgHeartbeat'. When 'MsgHeartbeatResp'
+	is passed to leader's Step method, the leader knows which follower
+	responded. And only when the leader's last committed index is greater than
+	follower's Match index, the leader runs 'sendAppend` method.
+
+	'MsgUnreachable' tells that request(message) wasn't delivered. When
+	'MsgUnreachable' is passed to leader's Step method, the leader discovers
+	that the follower that sent this 'MsgUnreachable' is not reachable, often
+	indicating 'MsgApp' is lost. When follower's progress state is replicate,
+	the leader sets it back to probe.

+/*
+Package wal provides an implementation of a write ahead log that is used by
+etcd.
+
+A WAL is created at a particular directory and is made up of a number of
+segmented WAL files. Inside of each file the raft state and entries are appended
+to it with the Save method:
+
+	metadata := []byte{}
+	w, err := wal.Create("/var/lib/etcd", metadata)
+	...
+	err := w.Save(s, ents)
+
+After saving a raft snapshot to disk, SaveSnapshot method should be called to
+record it. So WAL can match with the saved snapshot when restarting.
+
+	err := w.SaveSnapshot(walpb.Snapshot{Index: 10, Term: 2})
+
+When a user has finished using a WAL it must be closed:
+
+	w.Close()
+
+Each WAL file is a stream of WAL records. A WAL record is a length field and a wal record
+protobuf. The record protobuf contains a CRC, a type, and a data payload. The length field is a
+64-bit packed structure holding the length of the remaining logical record data in its lower
+56 bits and its physical padding in the first three bits of the most significant byte. Each
+record is 8-byte aligned so that the length field is never torn. The CRC contains the CRC32
+value of all record protobufs preceding the current record.
+
+WAL files are placed inside of the directory in the following format:
+$seq-$index.wal
+
+The first WAL file to be created will be 0000000000000000-0000000000000000.wal
+indicating an initial sequence of 0 and an initial raft index of 0. The first
+entry written to WAL MUST have raft index 0.
+
+WAL will cut its current tail wal file if its size exceeds 64MB. This will increment an internal
+sequence number and cause a new file to be created. If the last raft index saved
+was 0x20 and this is the first time cut has been called on this WAL then the sequence will
+increment from 0x0 to 0x1. The new file will be: 0000000000000001-0000000000000021.wal.
+If a second cut issues 0x10 entries with incremental index later then the file will be called:
+0000000000000002-0000000000000031.wal.
+
+At a later time a WAL can be opened at a particular snapshot. If there is no
+snapshot, an empty snapshot should be passed in.
+
+	w, err := wal.Open("/var/lib/etcd", walpb.Snapshot{Index: 10, Term: 2})
+	...
+
+The snapshot must have been written to the WAL.
+
+Additional items cannot be Saved to this WAL until all of the items from the given
+snapshot to the end of the WAL are read first:
+
+	metadata, state, ents, err := w.ReadAll()
+
+This will give you the metadata, the last raft.State and the slice of
+raft.Entry items in the log.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+// Package gomock is a mock framework for Go.
+//
+// Standard usage:
+//   (1) Define an interface that you wish to mock.
+//         type MyInterface interface {
+//           SomeMethod(x int64, y string)
+//         }
+//   (2) Use mockgen to generate a mock from the interface.
+//   (3) Use the mock in a test:
+//         func TestMyThing(t *testing.T) {
+//           mockCtrl := gomock.NewController(t)
+//           defer mockCtrl.Finish()
+//
+//           mockObj := something.NewMockMyInterface(mockCtrl)
+//           mockObj.EXPECT().SomeMethod(4, "blah")
+//           // pass mockObj to a real object and play with it.
+//         }
+//
+// By default, expected calls are not enforced to run in any particular order.
+// Call order dependency can be enforced by use of InOrder and/or Call.After.
+// Call.After can create more varied call order dependencies, but InOrder is
+// often more convenient.
+//
+// The following examples create equivalent call order dependencies.
+//
+// Example of using Call.After to chain expected call order:
+//
+//     firstCall := mockObj.EXPECT().SomeMethod(1, "first")
+//     secondCall := mockObj.EXPECT().SomeMethod(2, "second").After(firstCall)
+//     mockObj.EXPECT().SomeMethod(3, "third").After(secondCall)
+//
+// Example of using InOrder to declare expected call order:
+//
+//     gomock.InOrder(
+//         mockObj.EXPECT().SomeMethod(1, "first"),
+//         mockObj.EXPECT().SomeMethod(2, "second"),

-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.

-Equality is defined in this way:
-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map
-    fields are equal.
-  - Every other combination of things are not equal.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;

-	// tools.
-	//
-	// For example, say we have a file like:
-	//   message Foo {
-	//     optional string foo = 1;
-	//   }
-	// Let's look at just the field definition:
-	//   optional string foo = 1;
-	//   ^       ^^     ^^  ^  ^^^
-	//   a       bc     de  f  ghi
-	// We have the following locations:

-	//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
-	//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
-	//   [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
-	//   [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
-	//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
-	//
-	// Notes:
-	// - A location may refer to a repeated field itself (i.e. not to any
-	//   particular index within it).  This is used whenever a set of elements are
-	//   logically enclosed in a single code segment.  For example, an entire
-	//   extend block (possibly containing multiple extension definitions) will
-	//   have an outer location whose path refers to the "extensions" repeated
-	//   field without an index.
-	// - Multiple locations may have the same path.  This happens when a single
-	//   logical declaration is spread out across multiple places.  The most
-	//   obvious example is the "extend" block again -- there may be multiple
-	//   extend blocks in the same scope, each of which will have the same path.
-	// - A location's span is not always a subset of its parent's span.  For
-	//   example, the "extendee" of an extension declaration appears at the
-	//   beginning of the "extend" block and is shared by all extensions within
-	//   the block.
-	// - Just because a location's span is a subset of some other location's span
-	//   does not mean that it is a descendent.  For example, a "group" defines
-	//   both a type and a field in a single declaration.  Thus, the locations
-	//   corresponding to the type and field and their components will overlap.
-	// - Code which tries to interpret locations should probably be designed to
-	//   ignore those that it doesn't understand, as more types of locations could
-	//   be recorded in the future.

-// Options
-
-// Each of the definitions above may have "options" attached.  These are
-// just annotations which may cause code to be generated slightly differently
-// or may contain hints for code that manipulates protocol messages.
-//
-// Clients may define custom options as extensions of the *Options messages.
-// These extensions may not yet be known at parsing time, so the parser cannot
-// store the values in them.  Instead it stores them in a field in the *Options
-// message called uninterpreted_option. This field must have the same name
-// across all *Options messages. We then use this field to populate the
-// extensions when we build a descriptor, at which point all protos have been
-// parsed and so all extensions are known.
-//
-// Extension numbers for custom options may be chosen as follows:
-// * For options which will only be used within a single application or
-//   organization, or for experimental options, use field numbers 50000
-//   through 99999.  It is up to you to ensure that you do not use the
-//   same number for multiple options.
-// * For options which will be published and used publicly by multiple
-//   independent entities, e-mail protobuf-global-extension-registry@google.com
-//   to reserve extension numbers. Simply provide your project name (e.g.
-//   Objective-C plugin) and your project website (if available) -- there's no
-//   need to explain how you intend to use them. Usually you only need one
-//   extension number. You can declare multiple options with only one extension
-//   number by putting them in a sub-message. See the Custom Options section of
-//   the docs for examples:
-//   https://developers.google.com/protocol-buffers/docs/proto#options
-//   If this turns out to be popular, a web service will be set up
-//   to automatically assign option numbers.

-  // - A location may refer to a repeated field itself (i.e. not to any
-  //   particular index within it).  This is used whenever a set of elements are
-  //   logically enclosed in a single code segment.  For example, an entire
-  //   extend block (possibly containing multiple extension definitions) will
-  //   have an outer location whose path refers to the "extensions" repeated
-  //   field without an index.
-  // - Multiple locations may have the same path.  This happens when a single
-  //   logical declaration is spread out across multiple places.  The most
-  //   obvious example is the "extend" block again -- there may be multiple
-  //   extend blocks in the same scope, each of which will have the same path.
-  // - A location's span is not always a subset of its parent's span.  For
-  //   example, the "extendee" of an extension declaration appears at the
-  //   beginning of the "extend" block and is shared by all extensions within
-  //   the block.
-  // - Just because a location's span is a subset of some other location's span
-  //   does not mean that it is a descendent.  For example, a "group" defines
-  //   both a type and a field in a single declaration.  Thus, the locations
-  //   corresponding to the type and field and their components will overlap.

-    //       .name()           // 1

-	// should be indented the same amount as any inserted code will need to be
-	// in order to work correctly in that context.

-    // The double-@ is intended to make it unlikely that the generated code
-    // could contain things that look like insertion points by accident.
-    //

-    // .pb.h files that it generates:
-    //   // @@protoc_insertion_point(namespace_scope)
-    // This line appears within the scope of the file's package namespace, but

-    // insertion_point "namespace_scope" to generate additional classes or
-    // other declarations that should be placed in this scope.

-    // Note that if the line containing the insertion point begins with
-    // whitespace, the same whitespace will be added to every line of the
-    // inserted text.  This is useful for languages like Python, where
-    // indentation matters.  In these languages, the insertion point comment
-    // should be indented the same amount as any inserted code will need to be
-    // in order to work correctly in that context.
-    //
-    // The code generator that generates the initial file and the one which
-    // inserts into it must both run as part of a single invocation of protoc.

-    // command line.

-//     if (any.is(Foo.class)) {
-//       foo = any.unpack(Foo.class);
-//     }
-//
-//  Example 3: Pack and unpack a message in Python.
-//
-//     foo = Foo(...)
-//     any = Any()
-//     any.Pack(foo)

-//      foo := &pb.Foo{}
-//      if err := ptypes.UnmarshalAny(any, foo); err != nil {

-//      }
-//
-// The pack methods provided by protobuf library will by default use

-// methods only use the fully qualified type name after the last '/'
-// in the type URL, for example "foo.bar.com/x/y.z" will yield type
-// name "y.z".
-//
-//
-// JSON
-// ====
-// The JSON representation of an `Any` value uses the regular
-// representation of the deserialized, embedded message, with an
-// additional field `@type` which contains the type URL. Example:
-//
-//     package google.profile;
-//     message Person {
-//       string first_name = 1;
-//       string last_name = 2;
-//     }
-//
-//     {
-//       "@type": "type.googleapis.com/google.profile.Person",
-//       "firstName": <string>,
-//       "lastName": <string>
-//     }
-//
-// If the embedded message type is well-known and has a custom JSON
-// representation, that representation will be embedded adding a field
-// `value` which holds the custom JSON in addition to the `@type`
-// field. Example (for message [google.protobuf.Duration][]):
-//
-//     {
-//       "@type": "type.googleapis.com/google.protobuf.Duration",
-//       "value": "1.212s"
-//     }
-//
-type Any struct {
-	// A URL/resource name that uniquely identifies the type of the serialized
-	// protocol buffer message. The last segment of the URL's path must represent
-	// the fully qualified name of the type (as in
-	// `path/google.protobuf.Duration`). The name should be in a canonical form
-	// (e.g., leading "." is not accepted).
-	//
-	// In practice, teams usually precompile into the binary all types that they
-	// expect it to use in the context of Any. However, for URLs which use the
-	// scheme `http`, `https`, or no scheme, one can optionally set up a type
-	// server that maps type URLs to message definitions as follows:
-	//
-	// * If no scheme is provided, `https` is assumed.
-	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
-	//   value in binary format, or produce an error.
-	// * Applications are allowed to cache lookup results based on the
-	//   URL, or have them precompiled into a binary to avoid any
-	//   lookup. Therefore, binary compatibility needs to be preserved
-	//   on changes to types. (Use versioned type names to manage
-	//   breaking changes.)
-	//
-	// Note: this functionality is not currently available in the official
-	// protobuf release, and it is not used for type URLs beginning with
-	// type.googleapis.com.
-	//
-	// Schemes other than `http`, `https` (or the empty scheme) might be
-	// used with implementation specific semantics.
-	//
-	TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl,proto3" json:"type_url,omitempty"`

-  // In practice, teams usually precompile into the binary all types that they

-  // server that maps type URLs to message definitions as follows:
-  //
-  // * If no scheme is provided, `https` is assumed.
-  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
-  //   value in binary format, or produce an error.
-  // * Applications are allowed to cache lookup results based on the
-  //   URL, or have them precompiled into a binary to avoid any
-  //   lookup. Therefore, binary compatibility needs to be preserved
-  //   on changes to types. (Use versioned type names to manage
-  //   breaking changes.)
-  //
-  // Note: this functionality is not currently available in the official
-  // protobuf release, and it is not used for type URLs beginning with
-  // type.googleapis.com.

-// A Duration represents a signed, fixed-length span of time represented
-// as a count of seconds and fractions of seconds at nanosecond
-// resolution. It is independent of any calendar and concepts like "day"
-// or "month". It is related to Timestamp in that the difference between
-// two Timestamp values is a Duration and it can be added or subtracted
-// from a Timestamp. Range is approximately +-10,000 years.
-//
-// # Examples
-//
-// Example 1: Compute Duration from two Timestamps in pseudo code.
-//
-//     Timestamp start = ...;
-//     Timestamp end = ...;
-//     Duration duration = ...;
-//
-//     duration.seconds = end.seconds - start.seconds;

-//       duration.seconds -= 1;
-//       duration.nanos += 1000000000;
-//     }
-//
-// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
-//
-//     Timestamp start = ...;
-//     Duration duration = ...;
-//     Timestamp end = ...;
-//
-//     end.seconds = start.seconds + duration.seconds;
-//     end.nanos = start.nanos + duration.nanos;
-//
-//     if (end.nanos < 0) {
-//       end.seconds -= 1;
-//       end.nanos += 1000000000;
-//     } else if (end.nanos >= 1000000000) {
-//       end.seconds += 1;
-//       end.nanos -= 1000000000;
-//     }

-// Example 3: Compute Duration from datetime.timedelta in Python.
-//
-//     td = datetime.timedelta(days=3, minutes=10)
-//     duration = Duration()
-//     duration.FromTimedelta(td)
-//
-// # JSON Mapping
-//
-// In JSON format, the Duration type is encoded as a string rather than an
-// object, where the string ends in the suffix "s" (indicating seconds) and
-// is preceded by the number of seconds, with nanoseconds expressed as
-// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
-// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
-// be expressed in JSON format as "3.000000001s", and 3 seconds and 1
-// microsecond should be expressed in JSON format as "3.000001s".

-// A Duration represents a signed, fixed-length span of time represented
-// as a count of seconds and fractions of seconds at nanosecond
-// resolution. It is independent of any calendar and concepts like "day"
-// or "month". It is related to Timestamp in that the difference between
-// two Timestamp values is a Duration and it can be added or subtracted
-// from a Timestamp. Range is approximately +-10,000 years.
-//
-// # Examples
-//
-// Example 1: Compute Duration from two Timestamps in pseudo code.
-//
-//     Timestamp start = ...;
-//     Timestamp end = ...;
-//     Duration duration = ...;
-//
-//     duration.seconds = end.seconds - start.seconds;

-//     } else if (durations.seconds > 0 && duration.nanos < 0) {
-//       duration.seconds -= 1;
-//       duration.nanos += 1000000000;
-//     }
-//
-// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
-//
-//     Timestamp start = ...;
-//     Duration duration = ...;
-//     Timestamp end = ...;
-//
-//     end.seconds = start.seconds + duration.seconds;
-//     end.nanos = start.nanos + duration.nanos;
-//
-//     if (end.nanos < 0) {
-//       end.seconds -= 1;
-//       end.nanos += 1000000000;
-//     } else if (end.nanos >= 1000000000) {
-//       end.seconds += 1;
-//       end.nanos -= 1000000000;
-//     }
-//
-// Example 3: Compute Duration from datetime.timedelta in Python.
-//
-//     td = datetime.timedelta(days=3, minutes=10)
-//     duration = Duration()
-//     duration.FromTimedelta(td)
-//
-// # JSON Mapping
-//
-// In JSON format, the Duration type is encoded as a string rather than an
-// object, where the string ends in the suffix "s" (indicating seconds) and
-// is preceded by the number of seconds, with nanoseconds expressed as
-// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
-// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
-// be expressed in JSON format as "3.000000001s", and 3 seconds and 1
-// microsecond should be expressed in JSON format as "3.000001s".

-// # JSON Mapping
-//
-// In JSON format, the Timestamp type is encoded as a string in the
-// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
-// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
-// where {year} is always expressed using four digits while {month}, {day},
-// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
-// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
-// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
-// is required. A proto3 JSON serializer should always use UTC (as indicated by
-// "Z") when printing the Timestamp type and a proto3 JSON parser should be
-// able to accept both UTC and other timezones (as indicated by an offset).
-//
-// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
-// 01:30 UTC on January 15, 2017.
-//
-// In JavaScript, one can convert a Date object to this format using the
-// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString]
-// method. In Python, a standard `datetime.datetime` object can be converted
-// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
-// with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
-// can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
-// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime--
-// ) to obtain a formatter capable of generating timestamps in this format.

+	// The C++ snappy code calls this technique IncrementalCopyFastPath. Its

+	//
+	// ----
+	//
+	// The main part of this loop is a simple copy of eight bytes at a time
+	// until we've copied (at least) the requested amount of bytes.  However,
+	// if d and d-offset are less than eight bytes apart (indicating a
+	// repeating pattern of length < 8), we first need to expand the pattern in
+	// order to get the correct results. For instance, if the buffer looks like
+	// this, with the eight-byte <d-offset> and <d> patterns marked as
+	// intervals:
+	//
+	//    abxxxxxxxxxxxx
+	//    [------]           d-offset
+	//      [------]         d
+	//
+	// a single eight-byte copy from <d-offset> to <d> will repeat the pattern
+	// once, after which we can move <d> two bytes without moving <d-offset>:
+	//
+	//    ababxxxxxxxxxx
+	//    [------]           d-offset
+	//        [------]       d
+	//
+	// and repeat the exercise until the two no longer overlap.
+	//
+	// This allows us to do very well in the special case of one single byte
+	// repeated many times, without taking a big hit for more general cases.
+	//
+	// The worst case of extra writing past the end of the match occurs when
+	// offset == 1 and length == 1; the last copy will read from byte positions
+	// [0..7] and write to [4..11], whereas it was only supposed to write to
+	// position 1. Thus, ten excess bytes.

 //
+// Buffers
+//
+// Connections buffer network input and output to reduce the number
+// of system calls when reading or writing messages.
+//
+// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
+// Section 5 for a discussion of message framing. A WebSocket frame header is
+// written to the network each time a write buffer is flushed to the network.
+// Decreasing the size of the write buffer can increase the amount of framing
+// overhead on the connection.
+//
+// The buffer sizes in bytes are specified by the ReadBufferSize and
+// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
+// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
+// buffers created by the HTTP server when a buffer size field is set to zero.
+// The HTTP server buffers have a size of 4096 at the time of this writing.
+//
+// The buffer sizes do not limit the size of a message that can be read or
+// written by a connection.
+//
+// Buffers are held for the lifetime of the connection by default. If the
+// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
+// write buffer only when writing a message.
+//
+// Applications should tune the buffer sizes to balance memory use and
+// performance. Increasing the buffer size uses more memory, but can reduce the
+// number of system calls to read or write the network. In the case of writing,
+// increasing the buffer size can reduce the number of frame headers written to
+// the network.
+//
+// Some guidelines for setting buffer parameters are:
+//
+// Limit the buffer sizes to the maximum expected message size. Buffers larger
+// than the largest message do not provide any benefit.
+//
+// Depending on the distribution of message sizes, setting the buffer size to
+// a value less than the maximum expected message size can greatly reduce memory
+// use with a small impact on performance. Here's an example: If 99% of the
+// messages are smaller than 256 bytes and the maximum message size is 512
+// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
+// than a buffer size of 512 bytes. The memory savings is 50%.
+//
+// A write buffer pool is useful when the application has a modest number
+// writes over a large number of connections. when buffers are pooled, a larger
+// buffer size has a reduced impact on total memory use and has the benefit of
+// reducing system calls and frame overhead.
+//
 // Compression EXPERIMENTAL
 //
 // Per message compression extensions (RFC 7692) are experimentally supported

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# Notes on GSS-API Negotiation Mechanism
+https://tools.ietf.org/html/rfc4178
+
+Client sends an initial negotiation message to the server which specifies the list of mechanisms 
+the client can support in order of decreasing preference.
+This message is generated with the ``NewNegTokenInitKrb5`` method.
+The message generated by this function specifies only a kerberos v5 mechanism is supported.
+
+The RFC states that this message can optionally contain the initial mechanism token 
+for the preferred mechanism (KRB5 in this case) of the client. The ``NewNegTokenInitKrb5`` 
+includes this in the message.
+
+The server side responds to this message with a one of four messages:
+
+| Message Type/State | Description |
+|--------------------|-------------|
+| accept-completed | indicates that the initiator-selected mechanism was acceptable to the target, and that the security mechanism token embedded in the first negotiation message was sufficient to complete the authentication |
+| accept-incomplete | At least one more message is needed from the client to establish security context. |
+| reject | Negotiation is being terminated. |
+| request-mic | (this state can only be present in the first reply message from the target) indicates that the MIC token exchange is REQUIRED if per-message integrity services are available |

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

-# Usage
+**A simple fake clock for Go.**
+
+
+## Usage
 
 Replace uses of the `time` package with the `clockwork.Clock` interface instead.
 
 For example, instead of using `time.Sleep` directly:
 
-```
-func my_func() {
+```go
+func myFunc() {
 	time.Sleep(3 * time.Second)
-	do_something()
+	doSomething()
 }
 ```
 
-inject a clock and use its `Sleep` method instead:
+Inject a clock and use its `Sleep` method instead:
 
-```
-func my_func(clock clockwork.Clock) {
+```go
+func myFunc(clock clockwork.Clock) {
 	clock.Sleep(3 * time.Second)
-	do_something()
+	doSomething()
 }
 ```
 
-Now you can easily test `my_func` with a `FakeClock`:
+Now you can easily test `myFunc` with a `FakeClock`:
 
-```
+```go
 func TestMyFunc(t *testing.T) {
 	c := clockwork.NewFakeClock()
 
 	// Start our sleepy function
-	my_func(c)
+	var wg sync.WaitGroup
+	wg.Add(1)
+	go func() {
+		myFunc(c)
+		wg.Done()
+	}()
 
-	// Ensure we wait until my_func is sleeping
+	// Ensure we wait until myFunc is sleeping
 	c.BlockUntil(1)
 
-	assert_state()
+	assertState()
 
 	// Advance the FakeClock forward in time
-	c.Advance(3)
+	c.Advance(3 * time.Second)
 
-	assert_state()
+	// Wait until the function completes
+	wg.Wait()
+
+	assertState()
 }
 ```
 
 and in production builds, simply inject the real clock instead:
-```
-my_func(clockwork.NewRealClock())
+
+```go
+myFunc(clockwork.NewRealClock())
 ```
 
 See [example_test.go](example_test.go) for a full example.

+# Finite State Entropy
+
+This package provides Finite State Entropy encoding and decoding.
+            
+Finite State Entropy (also referenced as [tANS](https://en.wikipedia.org/wiki/Asymmetric_numeral_systems#tANS)) 
+encoding provides a fast near-optimal symbol encoding/decoding
+for byte blocks as implemented in [zstandard](https://github.com/facebook/zstd).
+
+This can be used for compressing input with a lot of similar input values to the smallest number of bytes.
+This does not perform any multi-byte [dictionary coding](https://en.wikipedia.org/wiki/Dictionary_coder) as LZ coders,
+but it can be used as a secondary step to compressors (like Snappy) that does not do entropy encoding. 
+
+* [Godoc documentation](https://godoc.org/github.com/klauspost/compress/fse)
+
+## News
+
+ * Feb 2018: First implementation released. Consider this beta software for now.
+
+# Usage
+
+This package provides a low level interface that allows to compress single independent blocks. 
+
+Each block is separate, and there is no built in integrity checks. 
+This means that the caller should keep track of block sizes and also do checksums if needed.  
+
+Compressing a block is done via the [`Compress`](https://godoc.org/github.com/klauspost/compress/fse#Compress) function.
+You must provide input and will receive the output and maybe an error.
+
+These error values can be returned:
+
+| Error               | Description                                                                 |
+|---------------------|-----------------------------------------------------------------------------|
+| `<nil>`             | Everything ok, output is returned                                           |
+| `ErrIncompressible` | Returned when input is judged to be too hard to compress                    |
+| `ErrUseRLE`         | Returned from the compressor when the input is a single byte value repeated |
+| `(error)`           | An internal error occurred.                                                 |
+
+As can be seen above there are errors that will be returned even under normal operation so it is important to handle these.
+
+To reduce allocations you can provide a [`Scratch`](https://godoc.org/github.com/klauspost/compress/fse#Scratch) object 
+that can be re-used for successive calls. Both compression and decompression accepts a `Scratch` object, and the same 
+object can be used for both.   
+
+Be aware, that when re-using a `Scratch` object that the *output* buffer is also re-used, so if you are still using this
+you must set the `Out` field in the scratch to nil. The same buffer is used for compression and decompression output.
+
+Decompressing is done by calling the [`Decompress`](https://godoc.org/github.com/klauspost/compress/fse#Decompress) function.
+You must provide the output from the compression stage, at exactly the size you got back. If you receive an error back
+your input was likely corrupted. 
+
+It is important to note that a successful decoding does *not* mean your output matches your original input. 
+There are no integrity checks, so relying on errors from the decompressor does not assure your data is valid.
+
+For more detailed usage, see examples in the [godoc documentation](https://godoc.org/github.com/klauspost/compress/fse#pkg-examples).
+
+# Performance
+
+A lot of factors are affecting speed. Block sizes and compressibility of the material are primary factors.  
+All compression functions are currently only running on the calling goroutine so only one core will be used per block.  
+
+The compressor is significantly faster if symbols are kept as small as possible. The highest byte value of the input
+is used to reduce some of the processing, so if all your input is above byte value 64 for instance, it may be 
+beneficial to transpose all your input values down by 64.   
+
+With moderate block sizes around 64k speed are typically 200MB/s per core for compression and 
+around 300MB/s decompression speed. 
+
+The same hardware typically does Huffman (deflate) encoding at 125MB/s and decompression at 100MB/s. 
+
+# Plans
+
+At one point, more internals will be exposed to facilitate more "expert" usage of the components. 
+
+A streaming interface is also likely to be implemented. Likely compatible with [FSE stream format](https://github.com/Cyan4973/FiniteStateEntropy/blob/dev/programs/fileio.c#L261).  
+
+# Contributing
+
+Contributions are always welcome. Be aware that adding public functions will require good justification and breaking 
+changes will likely not be accepted. If in doubt open an issue before writing the PR.

+# Huff0 entropy compression
+
+This package provides Huff0 encoding and decoding as used in zstd.
+            
+[Huff0](https://github.com/Cyan4973/FiniteStateEntropy#new-generation-entropy-coders), 
+a Huffman codec designed for modern CPU, featuring OoO (Out of Order) operations on multiple ALU 
+(Arithmetic Logic Unit), achieving extremely fast compression and decompression speeds.
+
+This can be used for compressing input with a lot of similar input values to the smallest number of bytes.
+This does not perform any multi-byte [dictionary coding](https://en.wikipedia.org/wiki/Dictionary_coder) as LZ coders,
+but it can be used as a secondary step to compressors (like Snappy) that does not do entropy encoding. 
+
+* [Godoc documentation](https://godoc.org/github.com/klauspost/compress/huff0)
+
+## News
+
+This is used as part of the [zstandard](https://github.com/klauspost/compress/tree/master/zstd#zstd) compression and decompression package.
+
+This ensures that most functionality is well tested.
+
+# Usage
+
+This package provides a low level interface that allows to compress single independent blocks. 
+
+Each block is separate, and there is no built in integrity checks. 
+This means that the caller should keep track of block sizes and also do checksums if needed.  
+
+Compressing a block is done via the [`Compress1X`](https://godoc.org/github.com/klauspost/compress/huff0#Compress1X) and 
+[`Compress4X`](https://godoc.org/github.com/klauspost/compress/huff0#Compress4X) functions.
+You must provide input and will receive the output and maybe an error.
+
+These error values can be returned:
+
+| Error               | Description                                                                 |
+|---------------------|-----------------------------------------------------------------------------|
+| `<nil>`             | Everything ok, output is returned                                           |
+| `ErrIncompressible` | Returned when input is judged to be too hard to compress                    |
+| `ErrUseRLE`         | Returned from the compressor when the input is a single byte value repeated |
+| `ErrTooBig`         | Returned if the input block exceeds the maximum allowed size (128 Kib)      |
+| `(error)`           | An internal error occurred.                                                 |
+
+
+As can be seen above some of there are errors that will be returned even under normal operation so it is important to handle these.
+
+To reduce allocations you can provide a [`Scratch`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch) object 
+that can be re-used for successive calls. Both compression and decompression accepts a `Scratch` object, and the same 
+object can be used for both.   
+
+Be aware, that when re-using a `Scratch` object that the *output* buffer is also re-used, so if you are still using this
+you must set the `Out` field in the scratch to nil. The same buffer is used for compression and decompression output.
+
+The `Scratch` object will retain state that allows to re-use previous tables for encoding and decoding.  
+
+## Tables and re-use
+
+Huff0 allows for reusing tables from the previous block to save space if that is expected to give better/faster results. 
+
+The Scratch object allows you to set a [`ReusePolicy`](https://godoc.org/github.com/klauspost/compress/huff0#ReusePolicy) 
+that controls this behaviour. See the documentation for details. This can be altered between each block.
+
+Do however note that this information is *not* stored in the output block and it is up to the users of the package to
+record whether [`ReadTable`](https://godoc.org/github.com/klauspost/compress/huff0#ReadTable) should be called,
+based on the boolean reported back from the CompressXX call. 
+
+If you want to store the table separate from the data, you can access them as `OutData` and `OutTable` on the 
+[`Scratch`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch) object.
+
+## Decompressing
+
+The first part of decoding is to initialize the decoding table through [`ReadTable`](https://godoc.org/github.com/klauspost/compress/huff0#ReadTable).
+This will initialize the decoding tables. 
+You can supply the complete block to `ReadTable` and it will return the data part of the block 
+which can be given to the decompressor. 
+
+Decompressing is done by calling the [`Decompress1X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress1X) 
+or [`Decompress4X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress4X) function.
+
+For concurrently decompressing content with a fixed table a stateless [`Decoder`](https://godoc.org/github.com/klauspost/compress/huff0#Decoder) can be requested which will remain correct as long as the scratch is unchanged. The capacity of the provided slice indicates the expected output size.
+
+You must provide the output from the compression stage, at exactly the size you got back. If you receive an error back
+your input was likely corrupted. 
+
+It is important to note that a successful decoding does *not* mean your output matches your original input. 
+There are no integrity checks, so relying on errors from the decompressor does not assure your data is valid.
+
+# Contributing
+
+Contributions are always welcome. Be aware that adding public functions will require good justification and breaking 
+changes will likely not be accepted. If in doubt open an issue before writing the PR.

+# zstd 
+
+[Zstandard](https://facebook.github.io/zstd/) is a real-time compression algorithm, providing high compression ratios. 
+It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder.
+A high performance compression algorithm is implemented. For now focused on speed. 
+
+This package provides [compression](#Compressor) to and [decompression](#Decompressor) of Zstandard content. 
+
+This package is pure Go and without use of "unsafe". 
+
+The `zstd` package is provided as open source software using a Go standard license.
+
+Currently the package is heavily optimized for 64 bit processors and will be significantly slower on 32 bit processors.
+
+## Installation
+
+Install using `go get -u github.com/klauspost/compress`. The package is located in `github.com/klauspost/compress/zstd`.
+
+Godoc Documentation: https://godoc.org/github.com/klauspost/compress/zstd
+
+
+## Compressor
+
+### Status: 
+
+STABLE - there may always be subtle bugs, a wide variety of content has been tested and the library is actively 
+used by several projects. This library is being [fuzz-tested](https://github.com/klauspost/compress-fuzz) for all updates.
+
+There may still be specific combinations of data types/size/settings that could lead to edge cases, 
+so as always, testing is recommended.  
+
+For now, a high speed (fastest) and medium-fast (default) compressor has been implemented. 
+
+* The "Fastest" compression ratio is roughly equivalent to zstd level 1. 
+* The "Default" compression ratio is roughly equivalent to zstd level 3 (default).
+* The "Better" compression ratio is roughly equivalent to zstd level 7.
+* The "Best" compression ratio is roughly equivalent to zstd level 11.
+
+In terms of speed, it is typically 2x as fast as the stdlib deflate/gzip in its fastest mode. 
+The compression ratio compared to stdlib is around level 3, but usually 3x as fast.
+
+ 
+### Usage
+
+An Encoder can be used for either compressing a stream via the
+`io.WriteCloser` interface supported by the Encoder or as multiple independent
+tasks via the `EncodeAll` function.
+Smaller encodes are encouraged to use the EncodeAll function.
+Use `NewWriter` to create a new instance that can be used for both.
+
+To create a writer with default options, do like this:
+
+```Go
+// Compress input to output.
+func Compress(in io.Reader, out io.Writer) error {
+    enc, err := zstd.NewWriter(out)
+    if err != nil {
+        return err
+    }
+    _, err = io.Copy(enc, in)
+    if err != nil {
+        enc.Close()
+        return err
+    }
+    return enc.Close()
+}
+```
+
+Now you can encode by writing data to `enc`. The output will be finished writing when `Close()` is called.
+Even if your encode fails, you should still call `Close()` to release any resources that may be held up.  
+
+The above is fine for big encodes. However, whenever possible try to *reuse* the writer.
+
+To reuse the encoder, you can use the `Reset(io.Writer)` function to change to another output. 
+This will allow the encoder to reuse all resources and avoid wasteful allocations. 
+
+Currently stream encoding has 'light' concurrency, meaning up to 2 goroutines can be working on part 
+of a stream. This is independent of the `WithEncoderConcurrency(n)`, but that is likely to change 
+in the future. So if you want to limit concurrency for future updates, specify the concurrency
+you would like.
+
+You can specify your desired compression level using `WithEncoderLevel()` option. Currently only pre-defined 
+compression settings can be specified.
+
+#### Future Compatibility Guarantees
+
+This will be an evolving project. When using this package it is important to note that both the compression efficiency and speed may change.
+
+The goal will be to keep the default efficiency at the default zstd (level 3). 
+However the encoding should never be assumed to remain the same, 
+and you should not use hashes of compressed output for similarity checks.
+
+The Encoder can be assumed to produce the same output from the exact same code version.
+However, the may be modes in the future that break this, 
+although they will not be enabled without an explicit option.   
+
+This encoder is not designed to (and will probably never) output the exact same bitstream as the reference encoder.
+
+Also note, that the cgo decompressor currently does not [report all errors on invalid input](https://github.com/DataDog/zstd/issues/59),
+[omits error checks](https://github.com/DataDog/zstd/issues/61), [ignores checksums](https://github.com/DataDog/zstd/issues/43) 
+and seems to ignore concatenated streams, even though [it is part of the spec](https://github.com/facebook/zstd/blob/dev/doc/zstd_compression_format.md#frames).
+
+#### Blocks
+
+For compressing small blocks, the returned encoder has a function called `EncodeAll(src, dst []byte) []byte`.
+
+`EncodeAll` will encode all input in src and append it to dst.
+This function can be called concurrently, but each call will only run on a single goroutine.
+
+Encoded blocks can be concatenated and the result will be the combined input stream.
+Data compressed with EncodeAll can be decoded with the Decoder, using either a stream or `DecodeAll`.
+
+Especially when encoding blocks you should take special care to reuse the encoder. 
+This will effectively make it run without allocations after a warmup period. 
+To make it run completely without allocations, supply a destination buffer with space for all content.   
+
+```Go
+import "github.com/klauspost/compress/zstd"
+
+// Create a writer that caches compressors.
+// For this operation type we supply a nil Reader.
+var encoder, _ = zstd.NewWriter(nil)
+
+// Compress a buffer. 
+// If you have a destination buffer, the allocation in the call can also be eliminated.
+func Compress(src []byte) []byte {
+    return encoder.EncodeAll(src, make([]byte, 0, len(src)))
+} 
+```
+
+You can control the maximum number of concurrent encodes using the `WithEncoderConcurrency(n)` 
+option when creating the writer.
+
+Using the Encoder for both a stream and individual blocks concurrently is safe. 
+
+### Performance
+
+I have collected some speed examples to compare speed and compression against other compressors.
+
+* `file` is the input file.
+* `out` is the compressor used. `zskp` is this package. `zstd` is the Datadog cgo library. `gzstd/gzkp` is gzip standard and this library.
+* `level` is the compression level used. For `zskp` level 1 is "fastest", level 2 is "default"; 3 is "better", 4 is "best".
+* `insize`/`outsize` is the input/output size.
+* `millis` is the number of milliseconds used for compression.
+* `mb/s` is megabytes (2^20 bytes) per second.

+## Decompressor
+
+Staus: STABLE - there may still be subtle bugs, but a wide variety of content has been tested.
+
+This library is being continuously [fuzz-tested](https://github.com/klauspost/compress-fuzz),
+kindly supplied by [fuzzit.dev](https://fuzzit.dev/). 
+The main purpose of the fuzz testing is to ensure that it is not possible to crash the decoder, 
+or run it past its limits with ANY input provided.  
+ 
+### Usage
+
+The package has been designed for two main usages, big streams of data and smaller in-memory buffers. 
+There are two main usages of the package for these. Both of them are accessed by creating a `Decoder`.
+
+For streaming use a simple setup could look like this:
+
+```Go
+import "github.com/klauspost/compress/zstd"
+
+func Decompress(in io.Reader, out io.Writer) error {
+    d, err := zstd.NewReader(in)
+    if err != nil {
+        return err
+    }
+    defer d.Close()
+    
+    // Copy content...
+    _, err = io.Copy(out, d)
+    return err
+}
+```
+
+It is important to use the "Close" function when you no longer need the Reader to stop running goroutines. 
+See "Allocation-less operation" below.
+
+For decoding buffers, it could look something like this:
+
+```Go
+import "github.com/klauspost/compress/zstd"
+
+// Create a reader that caches decompressors.
+// For this operation type we supply a nil Reader.
+var decoder, _ = zstd.NewReader(nil)
+
+// Decompress a buffer. We don't supply a destination buffer,
+// so it will be allocated by the decoder.
+func Decompress(src []byte) ([]byte, error) {
+    return decoder.DecodeAll(src, nil)
+} 
+```
+
+Both of these cases should provide the functionality needed. 
+The decoder can be used for *concurrent* decompression of multiple buffers. 
+It will only allow a certain number of concurrent operations to run. 
+To tweak that yourself use the `WithDecoderConcurrency(n)` option when creating the decoder.   
+
+### Dictionaries
+
+Data compressed with [dictionaries](https://github.com/facebook/zstd#the-case-for-small-data-compression) can be decompressed.
+
+Dictionaries are added individually to Decoders.
+Dictionaries are generated by the `zstd --train` command and contains an initial state for the decoder.
+To add a dictionary use the `WithDecoderDicts(dicts ...[]byte)` option with the dictionary data.
+Several dictionaries can be added at once.
+
+The dictionary will be used automatically for the data that specifies them.
+A re-used Decoder will still contain the dictionaries registered.
+
+When registering multiple dictionaries with the same ID, the last one will be used.
+
+It is possible to use dictionaries when compressing data.
+
+To enable a dictionary use `WithEncoderDict(dict []byte)`. Here only one dictionary will be used 
+and it will likely be used even if it doesn't improve compression. 
+
+The used dictionary must be used to decompress the content.
+
+For any real gains, the dictionary should be built with similar data. 
+If an unsuitable dictionary is used the output may be slightly larger than using no dictionary.
+Use the [zstd commandline tool](https://github.com/facebook/zstd/releases) to build a dictionary from sample data.
+For information see [zstd dictionary information](https://github.com/facebook/zstd#the-case-for-small-data-compression). 
+
+For now there is a fixed startup performance penalty for compressing content with dictionaries. 
+This will likely be improved over time. Just be aware to test performance when implementing.  
+
+### Allocation-less operation
+
+The decoder has been designed to operate without allocations after a warmup. 
+
+This means that you should *store* the decoder for best performance. 
+To re-use a stream decoder, use the `Reset(r io.Reader) error` to switch to another stream.
+A decoder can safely be re-used even if the previous stream failed.
+
+To release the resources, you must call the `Close()` function on a decoder.
+After this it can *no longer be reused*, but all running goroutines will be stopped.
+So you *must* use this if you will no longer need the Reader.
+
+For decompressing smaller buffers a single decoder can be used.
+When decoding buffers, you can supply a destination slice with length 0 and your expected capacity.
+In this case no unneeded allocations should be made. 
+
+### Concurrency
+
+The buffer decoder does everything on the same goroutine and does nothing concurrently.
+It can however decode several buffers concurrently. Use `WithDecoderConcurrency(n)` to limit that.
+
+The stream decoder operates on
+
+* One goroutine reads input and splits the input to several block decoders.
+* A number of decoders will decode blocks.
+* A goroutine coordinates these blocks and sends history from one to the next.
+
+So effectively this also means the decoder will "read ahead" and prepare data to always be available for output.
+
+Since "blocks" are quite dependent on the output of the previous block stream decoding will only have limited concurrency.
+
+In practice this means that concurrency is often limited to utilizing about 2 cores effectively.
+ 
+ 
+### Benchmarks
+
+These are some examples of performance compared to [datadog cgo library](https://github.com/DataDog/zstd).
+
+The first two are streaming decodes and the last are smaller inputs.

+# xxhash
+
+VENDORED: Go to [github.com/cespare/xxhash](https://github.com/cespare/xxhash) for original package.
+
+
+[![GoDoc](https://godoc.org/github.com/cespare/xxhash?status.svg)](https://godoc.org/github.com/cespare/xxhash)
+[![Build Status](https://travis-ci.org/cespare/xxhash.svg?branch=master)](https://travis-ci.org/cespare/xxhash)
+
+xxhash is a Go implementation of the 64-bit
+[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
+high-quality hashing algorithm that is much faster than anything in the Go
+standard library.
+
+This package provides a straightforward API:
+
+```
+func Sum64(b []byte) uint64
+func Sum64String(s string) uint64
+type Digest struct{ ... }
+    func New() *Digest
+```
+
+The `Digest` type implements hash.Hash64. Its key methods are:
+
+```
+func (*Digest) Write([]byte) (int, error)
+func (*Digest) WriteString(string) (int, error)
+func (*Digest) Sum64() uint64
+```
+
+This implementation provides a fast pure-Go implementation and an even faster
+assembly implementation for amd64.
+
+## Benchmarks
+
+Here are some quick benchmarks comparing the pure-Go and assembly
+implementations of Sum64.
+
+| input size | purego | asm |
+| --- | --- | --- |
+| 5 B   |  979.66 MB/s |  1291.17 MB/s  |
+| 100 B | 7475.26 MB/s | 7973.40 MB/s  |
+| 4 KB  | 17573.46 MB/s | 17602.65 MB/s |
+| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
+
+These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
+the following commands under Go 1.11.2:
+
+```
+$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
+$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
+```

+## Roadmap
+
+With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
+
+- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
+- 1.0. Final release.
+
 ## Contributing
 
-We welcome pull requests, bug fixes and issue reports. With that said, the bar for adding new symbols to this package is intentionally set high.
+Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports. 
 
-Before proposing a change, please discuss your change by raising an issue.
+Before sending a PR, please discuss your change by raising an issue.

 //
-// 1. The performance impact of stopping the world is the more relevant the more

-// stop-the-world time per metrics collection is very short (~25µs) so that the
-// performance impact will only matter in rare cases. However, with older Go

-// quite significant (~1.7 ms/GiB as per
-// https://go-review.googlesource.com/c/go/+/34937).
-//
-// 2. During an ongoing GC, nothing else can stop the world. Therefore, if the
-// metrics collection happens to coincide with GC, it will only complete after
-// GC has finished. Usually, GC is fast enough to not cause problems. However,

+//   line, info type, stateset type, gaugehistogram type.
+//

+
+## Steps to Contribute
+
+Should you wish to work on an issue, please claim it first by commenting on the GitHub issue that you want to work on it. This is to prevent duplicated efforts from contributors on the same issue.
+
+Please check the [`help-wanted`](https://github.com/prometheus/procfs/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) label to find issues that are good for getting started. If you have questions about one of the issues, with or without the tag, please comment on them and one of the maintainers will clarify it. For a quicker response, contact us over [IRC](https://prometheus.io/community).
+
+For quickly compiling and testing your changes do:
+```
+make test         # Make sure all the tests pass before you commit and push :)
+```
+
+We use [`golangci-lint`](https://github.com/golangci/golangci-lint) for linting the code. If it reports an issue and you think that the warning needs to be disregarded or is a false-positive, you can add a special comment `//nolint:linter1[,linter2,...]` before the offending line. Use this sparingly though, fixing the code to comply with the linter's recommendation is in general the preferred course of action.
+
+## Pull Request Checklist
+
+* Branch from the master branch and, if needed, rebase to the current master branch before submitting your pull request. If it doesn't merge cleanly with master you may be asked to rebase your changes.
+
+* Commits should be as small as possible, while ensuring that each commit is correct independently (i.e., each commit should compile and pass tests).
+
+* If your patch is not getting reviewed or you need a specific person to review it, you can @-reply a reviewer asking for a review in the pull request or a comment, or you can ask for a review on IRC channel [#prometheus](https://webchat.freenode.net/?channels=#prometheus) on irc.freenode.net (for the easiest start, [join via Riot](https://riot.im/app/#/room/#prometheus:matrix.org)).
+
+* Add tests relevant to the fixed bug or new feature.
+
+## Dependency management
+
+The Prometheus project uses [Go modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) to manage dependencies on external packages. This requires a working Go environment with version 1.12 or greater installed.
+
+All dependencies are vendored in the `vendor/` directory.
+
+To add or update a new dependency, use the `go get` command:
+
+```bash
+# Pick the latest tagged release.
+go get example.com/some/module/pkg
+
+# Pick a specific version.
+go get example.com/some/module/pkg@vX.Y.Z
+```
+
+Tidy up the `go.mod` and `go.sum` files and copy the new/updated dependency to the `vendor/` directory:
+
+
+```bash
+# The GO111MODULE variable can be omitted when the code isn't located in GOPATH.
+GO111MODULE=on go mod tidy
+
+GO111MODULE=on go mod vendor
+```
+
+You have to commit the changes to `go.mod`, `go.sum` and the `vendor/` directory before submitting the pull request.
+
+
+## API Implementation Guidelines
+
+### Naming and Documentation
+
+Public functions and structs should normally be named according to the file(s) being read and parsed.  For example, 
+the `fs.BuddyInfo()` function reads the file `/proc/buddyinfo`.  In addition, the godoc for each public function
+should contain the path to the file(s) being read and a URL of the linux kernel documentation describing the file(s).
+
+### Reading vs. Parsing
+
+Most functionality in this library consists of reading files and then parsing the text into structured data.  In most
+cases reading and parsing should be separated into different functions/methods with a public `fs.Thing()` method and 
+a private `parseThing(r Reader)` function.  This provides a logical separation and allows parsing to be tested
+directly without the need to read from the filesystem.  Using a `Reader` argument is preferred over other data types
+such as `string` or `*File` because it provides the most flexibility regarding the data source.  When a set of files 
+in a directory needs to be parsed, then a `path` string parameter to the parse function can be used instead.
+
+### /proc and /sys filesystem I/O 
+
+The `proc` and `sys` filesystems are pseudo file systems and work a bit differently from standard disk I/O.  
+Many of the files are changing continuously and the data being read can in some cases change between subsequent 
+reads in the same file.  Also, most of the files are relatively small (less than a few KBs), and system calls
+to the `stat` function will often return the wrong size.  Therefore, for most files it's recommended to read the 
+full file in a single operation using an internal utility function called `util.ReadFileNoStat`.
+This function is similar to `ioutil.ReadFile`, but it avoids the system call to `stat` to get the current size of
+the file.
+
+Note that parsing the file's contents can still be performed one line at a time.  This is done by first reading 
+the full file, and then using a scanner on the `[]byte` or `string` containing the data.
+
+```
+    data, err := util.ReadFileNoStat("/proc/cpuinfo")
+    if err != nil {
+        return err
+    }
+    reader := bytes.NewReader(data)
+    scanner := bufio.NewScanner(reader)
+```
+
+The `/sys` filesystem contains many very small files which contain only a single numeric or text value.  These files
+can be read using an internal function called `util.SysReadFile` which is similar to `ioutil.ReadFile` but does
+not bother to check the size of the file before reading.
+```
+    data, err := util.SysReadFile("/sys/class/power_supply/BAT0/capacity")
+```

+## Package Organization
+
+The packages in this project are organized according to (1) whether the data comes from the `/proc` or
+`/sys` filesystem and (2) the type of information being retrieved.  For example, most process information
+can be gathered from the functions in the root `procfs` package.  Information about block devices such as disk drives

 ## Building and Testing
 
-The procfs library is normally built as part of another application.  However, when making
-changes to the library, the `make test` command can be used to run the API test suite.
+The procfs library is intended to be built as part of another application, so there are no distributable binaries.

+	// For example, on a system with 1G of physical RAM and 7G
+	// of swap with a `vm.overcommit_ratio` of 30 it would

+	// The amount of memory presently allocated on the system.

+	// by the VM and can be used at any time by the allocating
+	// application. With strict overcommit enabled on the system
+	// (mode 2 in 'vm.overcommit_memory'),allocations which would
+	// exceed the CommitLimit (detailed above) will not be permitted.

 Logrus is a structured logger for Go (golang), completely API compatible with
 the standard library logger.
 
+**Logrus is in maintenance-mode.** We will not be introducing new features. It's
+simply too hard to do in a way that won't break many people's projects, which is
+the last thing you want from your Logging library (again...).
+
+This does not mean Logrus is dead. Logrus will continue to be maintained for
+security, (backwards compatible) bug fixes, and performance (where we are
+limited by the interface). 
+
+I believe Logrus' biggest contribution is to have played a part in today's
+widespread use of structured logging in Golang. There doesn't seem to be a
+reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
+community has built those independently. Many fantastic alternatives have sprung
+up. Logrus would look like those, had it been re-designed with what we know
+about structured logging in Go today. Check out, for example,
+[Zerolog][zerolog], [Zap][zap], and [Apex][apex].

-## Description
-
-pflag is a drop-in replacement for Go's flag package, implementing
-POSIX/GNU-style --flags.
-
-pflag is compatible with the [GNU extensions to the POSIX recommendations
-for command-line options][1]. For a more precise description, see the
-"Command-line flag syntax" section below.
-
-[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
-
-pflag is available under the same style of BSD license as the Go language,
-which can be found in the LICENSE file.
-
-## Installation
-
-pflag is available using the standard `go get` command.
-
-Install by running:
-
-    go get github.com/spf13/pflag
-
-Run tests by running:
-
-    go test github.com/spf13/pflag
-
-## Usage
-
-pflag is a drop-in replacement of Go's native flag package. If you import
-pflag under the name "flag" then all code should continue to function
-with no changes.
-
-``` go
-import flag "github.com/spf13/pflag"
-```
-
-There is one exception to this: if you directly instantiate the Flag struct
-there is one more field "Shorthand" that you will need to set.
-Most code never instantiates this struct directly, and instead uses
-functions such as String(), BoolVar(), and Var(), and is therefore
-unaffected.
-
-Define flags using flag.String(), Bool(), Int(), etc.
-
-This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
-
-``` go
-var ip *int = flag.Int("flagname", 1234, "help message for flagname")
-```
-
-If you like, you can bind the flag to a variable using the Var() functions.
-
-``` go
-var flagvar int
-func init() {
-    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
-}
-```
-
-Or you can create custom flags that satisfy the Value interface (with
-pointer receivers) and couple them to flag parsing by
-
-``` go
-flag.Var(&flagVal, "name", "help message for flagname")
-```
-
-For such flags, the default value is just the initial value of the variable.
-
-After all flags are defined, call
-
-``` go
-flag.Parse()
-```
-
-to parse the command line into the defined flags.
-
-Flags may then be used directly. If you're using the flags themselves,
-they are all pointers; if you bind to variables, they're values.
-
-``` go
-fmt.Println("ip has value ", *ip)
-fmt.Println("flagvar has value ", flagvar)
-```
-
-There are helpers function to get values later if you have the FlagSet but
-it was difficult to keep up with all of the flag pointers in your code.
-If you have a pflag.FlagSet with a flag called 'flagname' of type int you
-can use GetInt() to get the int value. But notice that 'flagname' must exist
-and it must be an int. GetString("flagname") will fail.
-
-``` go
-i, err := flagset.GetInt("flagname")
-```
-
-After parsing, the arguments after the flag are available as the
-slice flag.Args() or individually as flag.Arg(i).
-The arguments are indexed from 0 through flag.NArg()-1.
-
-The pflag package also defines some new functions that are not in flag,
-that give one-letter shorthands for flags. You can use these by appending
-'P' to the name of any function that defines a flag.
-
-``` go
-var ip = flag.IntP("flagname", "f", 1234, "help message")
-var flagvar bool
-func init() {
-	flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
-}
-flag.VarP(&flagVal, "varname", "v", "help message")
-```
-
-Shorthand letters can be used with single dashes on the command line.
-Boolean shorthand flags can be combined with other shorthand flags.
-
-The default set of command-line flags is controlled by
-top-level functions.  The FlagSet type allows one to define
-independent sets of flags, such as to implement subcommands
-in a command-line interface. The methods of FlagSet are
-analogous to the top-level functions for the command-line
-flag set.
-
-## Setting no option default values for flags
-
-After you create a flag it is possible to set the pflag.NoOptDefVal for
-the given flag. Doing this changes the meaning of the flag slightly. If
-a flag has a NoOptDefVal and the flag is set on the command line without
-an option the flag will be set to the NoOptDefVal. For example given:
-
-``` go
-var ip = flag.IntP("flagname", "f", 1234, "help message")
-flag.Lookup("flagname").NoOptDefVal = "4321"
-```
-
-Would result in something like
-
-| Parsed Arguments | Resulting Value |
-| -------------    | -------------   |
-| --flagname=1357  | ip=1357         |
-| --flagname       | ip=4321         |
-| [nothing]        | ip=1234         |
-
-## Command line flag syntax
-
-```
---flag    // boolean flags, or flags with no option default values
---flag x  // only on flags without a default value
---flag=x
-```
-
-Unlike the flag package, a single dash before an option means something
-different than a double dash. Single dashes signify a series of shorthand
-letters for flags. All but the last shorthand letter must be boolean flags
-or a flag with a default value
-
-```
-// boolean or flags where the 'no option default value' is set
--f
--f=true
--abc
-but
--b true is INVALID
-
-// non-boolean and flags without a 'no option default value'
--n 1234
--n=1234
--n1234
-
-// mixed
--abcs "hello"
--absd="hello"
--abcs1234
-```
-
-Flag parsing stops after the terminator "--". Unlike the flag package,
-flags can be interspersed with arguments anywhere on the command line
-before this terminator.
-
-Integer flags accept 1234, 0664, 0x1234 and may be negative.
-Boolean flags (in their long form) accept 1, 0, t, f, true, false,
-TRUE, FALSE, True, False.
-Duration flags accept any input valid for time.ParseDuration.
-
-## Mutating or "Normalizing" Flag names
-
-It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
-
-**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
-
-``` go
-func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
-	from := []string{"-", "_"}
-	to := "."
-	for _, sep := range from {
-		name = strings.Replace(name, sep, to, -1)
-	}
-	return pflag.NormalizedName(name)
-}
-
-myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
-```
-
-**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
-
-``` go
-func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
-	switch name {
-	case "old-flag-name":
-		name = "new-flag-name"
-		break
-	}
-	return pflag.NormalizedName(name)
-}
-
-myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
-```
-
-## Deprecating a flag or its shorthand
-It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
-
-**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
-```go
-// deprecate a flag by specifying its name and a usage message
-flags.MarkDeprecated("badflag", "please use --good-flag instead")
-```
-This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
-
-**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
-```go
-// deprecate a flag shorthand by specifying its flag name and a usage message
-flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
-```
-This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
-
-Note that usage message is essential here, and it should not be empty.
-
-## Hidden flags
-It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
-
-**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
-```go
-// hide a flag by specifying its name
-flags.MarkHidden("secretFlag")
-```
-
-## Disable sorting of flags
-`pflag` allows you to disable sorting of flags for help and usage message.
-
-**Example**:
-```go
-flags.BoolP("verbose", "v", false, "verbose output")
-flags.String("coolflag", "yeaah", "it's really cool flag")
-flags.Int("usefulflag", 777, "sometimes it's very useful")
-flags.SortFlags = false
-flags.PrintDefaults()
-```
-**Output**:

-## Supporting Go flags when using pflag
-In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
-to support flags defined by third-party dependencies (e.g. `golang/glog`).
-
-**Example**: You want to add the Go flags to the `CommandLine` flagset
-```go
-import (
-	goflag "flag"
-	flag "github.com/spf13/pflag"
-)
-
-var ip *int = flag.Int("flagname", 1234, "help message for flagname")
-
-func main() {
-	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
-	flag.Parse()
-}
-```
-
-## More info
-
-You can see the full reference documentation of the pflag package
-[at godoc.org][3], or through go's standard documentation system by
-running `godoc -http=:6060` and browsing to
-[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
-installation.

-Package pflag is a drop-in replacement for Go's flag package, implementing
-POSIX/GNU-style --flags.
-
-pflag is compatible with the GNU extensions to the POSIX recommendations
-for command-line options. See
-http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
-
-Usage:
-
-pflag is a drop-in replacement of Go's native flag package. If you import
-pflag under the name "flag" then all code should continue to function
-with no changes.
-
-	import flag "github.com/spf13/pflag"
-
-There is one exception to this: if you directly instantiate the Flag struct
-there is one more field "Shorthand" that you will need to set.
-Most code never instantiates this struct directly, and instead uses
-functions such as String(), BoolVar(), and Var(), and is therefore
-unaffected.
-
-Define flags using flag.String(), Bool(), Int(), etc.
-
-This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
-	var ip = flag.Int("flagname", 1234, "help message for flagname")
-If you like, you can bind the flag to a variable using the Var() functions.
-	var flagvar int
-	func init() {
-		flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
-	}
-Or you can create custom flags that satisfy the Value interface (with
-pointer receivers) and couple them to flag parsing by
-	flag.Var(&flagVal, "name", "help message for flagname")
-For such flags, the default value is just the initial value of the variable.
-
-After all flags are defined, call
-	flag.Parse()
-to parse the command line into the defined flags.
-
-Flags may then be used directly. If you're using the flags themselves,
-they are all pointers; if you bind to variables, they're values.
-	fmt.Println("ip has value ", *ip)
-	fmt.Println("flagvar has value ", flagvar)
-
-After parsing, the arguments after the flag are available as the
-slice flag.Args() or individually as flag.Arg(i).
-The arguments are indexed from 0 through flag.NArg()-1.
-
-The pflag package also defines some new functions that are not in flag,
-that give one-letter shorthands for flags. You can use these by appending
-'P' to the name of any function that defines a flag.
-	var ip = flag.IntP("flagname", "f", 1234, "help message")
-	var flagvar bool
-	func init() {
-		flag.BoolVarP("boolname", "b", true, "help message")
-	}
-	flag.VarP(&flagVar, "varname", "v", 1234, "help message")
-Shorthand letters can be used with single dashes on the command line.
-Boolean shorthand flags can be combined with other shorthand flags.
-
-Command line flag syntax:
-	--flag    // boolean flags only
-	--flag=x
-
-Unlike the flag package, a single dash before an option means something
-different than a double dash. Single dashes signify a series of shorthand
-letters for flags. All but the last shorthand letter must be boolean flags.
-	// boolean flags
-	-f
-	-abc
-	// non-boolean flags
-	-n 1234
-	-Ifile
-	// mixed
-	-abcs "hello"
-	-abcn1234
-
-Flag parsing stops after the terminator "--". Unlike the flag package,
-flags can be interspersed with arguments anywhere on the command line
-before this terminator.
-
-Integer flags accept 1234, 0664, 0x1234 and may be negative.
-Boolean flags (in their long form) accept 1, 0, t, f, true, false,
-TRUE, FALSE, True, False.
-Duration flags accept any input valid for time.ParseDuration.
-
-The default set of command-line flags is controlled by
-top-level functions.  The FlagSet type allows one to define
-independent sets of flags, such as to implement subcommands
-in a command-line interface. The methods of FlagSet are
-analogous to the top-level functions for the command-line
-flag set.

 ### Environment variables
 
-The tracer can be initialized with values coming from environment variables. None of the env vars are required
-and all of them can be overridden via direct setting of the property on the configuration object.
+The tracer can be initialized with values coming from environment variables, if it is
+[built from a config](https://pkg.go.dev/github.com/uber/jaeger-client-go/config?tab=doc#Configuration.NewTracer)
+that was created via [FromEnv()](https://pkg.go.dev/github.com/uber/jaeger-client-go/config?tab=doc#FromEnv).
+None of the env vars are required and all of them can be overridden via direct setting 
+of the property on the configuration object.
 
 Property| Description
 --- | ---
-JAEGER_SERVICE_NAME | The service name
-JAEGER_AGENT_HOST | The hostname for communicating with agent via UDP
-JAEGER_AGENT_PORT | The port for communicating with agent via UDP
-JAEGER_ENDPOINT | The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces
-JAEGER_USER | Username to send as part of "Basic" authentication to the collector endpoint
-JAEGER_PASSWORD | Password to send as part of "Basic" authentication to the collector endpoint
-JAEGER_REPORTER_LOG_SPANS | Whether the reporter should also log the spans
-JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size
-JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval, with units, e.g. "500ms" or "2s" ([valid units][timeunits])
-JAEGER_SAMPLER_TYPE | The sampler type
-JAEGER_SAMPLER_PARAM | The sampler parameter (number)
-JAEGER_SAMPLER_MANAGER_HOST_PORT | The HTTP endpoint when using the remote sampler, i.e. http://jaeger-agent:5778/sampling
-JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of
-JAEGER_SAMPLER_REFRESH_INTERVAL | How often the remotely controlled sampler will poll jaeger-agent for the appropriate sampling strategy, with units, e.g. "1m" or "30s" ([valid units][timeunits])
-JAEGER_TAGS | A comma separated list of `name = value` tracer level tags, which get added to all reported spans. The value can also refer to an environment variable using the format `${envVarName:default}`, where the `:default` is optional, and identifies a value to be used if the environment variable cannot be found
-JAEGER_DISABLED | Whether the tracer is disabled or not. If true, the default `opentracing.NoopTracer` is used.
-JAEGER_RPC_METRICS | Whether to store RPC metrics
+JAEGER_SERVICE_NAME | The service name.
+JAEGER_AGENT_HOST | The hostname for communicating with agent via UDP (default `localhost`).
+JAEGER_AGENT_PORT | The port for communicating with agent via UDP (default `6831`).
+JAEGER_ENDPOINT | The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces. If specified, the agent host/port are ignored.
+JAEGER_USER | Username to send as part of "Basic" authentication to the collector endpoint.
+JAEGER_PASSWORD | Password to send as part of "Basic" authentication to the collector endpoint.
+JAEGER_REPORTER_LOG_SPANS | Whether the reporter should also log the spans" `true` or `false` (default `false`).
+JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size (default `100`).
+JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval, with units, e.g. `500ms` or `2s` ([valid units][timeunits]; default `1s`).
+JAEGER_REPORTER_ATTEMPT_RECONNECTING_DISABLED | When true, disables udp connection helper that periodically re-resolves the agent's hostname and reconnects if there was a change (default `false`).
+JAEGER_REPORTER_ATTEMPT_RECONNECT_INTERVAL | Controls how often the agent client re-resolves the provided hostname in order to detect address changes ([valid units][timeunits]; default `30s`).
+JAEGER_SAMPLER_TYPE | The sampler type: `remote`, `const`, `probabilistic`, `ratelimiting` (default `remote`). See also https://www.jaegertracing.io/docs/latest/sampling/.
+JAEGER_SAMPLER_PARAM | The sampler parameter (number).
+JAEGER_SAMPLER_MANAGER_HOST_PORT | (deprecated) The HTTP endpoint when using the `remote` sampler.
+JAEGER_SAMPLING_ENDPOINT | The URL for the sampling configuration server when using sampler type `remote` (default `http://127.0.0.1:5778/sampling`).
+JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of (default `2000`).
+JAEGER_SAMPLER_REFRESH_INTERVAL | How often the `remote` sampler should poll the configuration server for the appropriate sampling strategy, e.g. "1m" or "30s" ([valid units][timeunits]; default `1m`).
+JAEGER_TAGS | A comma separated list of `name=value` tracer-level tags, which get added to all reported spans. The value can also refer to an environment variable using the format `${envVarName:defaultValue}`.
+JAEGER_DISABLED | Whether the tracer is disabled or not. If `true`, the `opentracing.NoopTracer` is used (default `false`).
+JAEGER_RPC_METRICS | Whether to store RPC metrics, `true` or `false` (default `false`).
 
 By default, the client sends traces via UDP to the agent at `localhost:6831`. Use `JAEGER_AGENT_HOST` and
 `JAEGER_AGENT_PORT` to send UDP traces to a different `host:port`. If `JAEGER_ENDPOINT` is set, the client sends traces
