+# Zstd Go Wrapper
+
+[C Zstd Homepage](https://github.com/Cyan4973/zstd)
+
+The current headers and C files are from *v1.3.4* (Commit
+[2555975](https://github.com/facebook/zstd/releases/tag/v1.3.4)).
+
+## 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()).

+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,

+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'.

+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`).

+The first thing to do is to init bitStream and state.
+ 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()).
+ size_t size = BIT_closeCStream(&bitStream);

+Let's now decompose FSE_decompress_usingDTable() into its unitary components.
+You will decode FSE-encoded symbols from the bitStream,
+and also any other bitFields you put in, **in reverse order**.
+
+You will need a few variables to track your bitStream. They are :
+
+BIT_DStream_t DStream; // Stream context
+FSE_DState_t DState; // State context. Multiple ones are possible
+FSE_DTable* DTablePtr; // Decoding table, provided by FSE_buildDTable()
+
+The first thing to do is to init the bitStream.
+ errorCode = BIT_initDStream(&DStream, srcBuffer, srcSize);
+
+You should then retrieve your initial state(s)
+(in reverse flushing order if you have several ones) :
+ errorCode = FSE_initDState(&DState, &DStream, DTablePtr);
+
+You can then decode your data, symbol after symbol.
+For information the maximum number of bits read by FSE_decodeSymbol() is 'tableLog'.
+Keep in mind that symbols are decoded in reverse order, like a LIFO stack (last in, first out).
+ unsigned char symbol = FSE_decodeSymbol(&DState, &DStream);
+
+You can retrieve any bitfield you eventually stored into the bitStream (in reverse order)
+Note : maximum allowed nbBits is 25, for 32-bits compatibility
+ size_t bitField = BIT_readBits(&DStream, nbBits);
+
+All above operations only read from local register (which size depends on size_t).
+Refueling the register from memory is manually performed by the reload method.
+ endSignal = FSE_reloadDStream(&DStream);
+
+BIT_reloadDStream() result tells if there is still some more data to read from DStream.
+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.

+ * 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.

+
+xxHash is an extremely fast Hash algorithm, running at RAM speed limits.
+It also successfully passes all tests from the SMHasher suite.
+

+
+Q.Score is a measure of quality of the hash function.
+It depends on successfully passing SMHasher test set.
+10 is a perfect score.
+

+* 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().

+* 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.

+* 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 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.
+ 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 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 shall never be used with a dynamic library.
+ They are not "stable", their definition may change in the future. Only static linking is allowed.

+* since it will play nicer with system's memory, by re-using already allocated memory.
+* Use one separate ZSTD_CStream per thread for parallel execution.
+*
+* Start a new compression by initializing ZSTD_CStream.
+* Use ZSTD_initCStream() to start a new compression operation.
+* Use ZSTD_initCStream_usingDict() or ZSTD_initCStream_usingCDict() for a compression which requires a dictionary (experimental section)
+*
+* Use ZSTD_compressStream() repetitively to consume input stream.

+ - 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.

+ 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.

+ * 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)

+ * Method 0 (default) : use `memcpy()`. Safe and portable.

+ * 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)

+
+ 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 .

+ @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.

+* 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, direct mode (bufferless)

+ 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.

+ - 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 .

+ 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;

+ [#1008](https://github.com/Shopify/sarama/pull/1008)).
+ - Add support for the Describe/Create/Delete ACL request/response pairs
+ ([#1009](https://github.com/Shopify/sarama/pull/1009)).
+ - Add support for the five transaction-related request/response pairs
+ ([#1016](https://github.com/Shopify/sarama/pull/1016)).
+
+Improvements:
+ - Permit setting version on mock producer responses
+ ([#999](https://github.com/Shopify/sarama/pull/999)).
+ - Add `NewMockBrokerListener` helper for testing TLS connections
+ ([#1019](https://github.com/Shopify/sarama/pull/1019)).
+ - Changed the default value for `Consumer.Fetch.Default` from 32KiB to 1MiB
+ which results in much higher throughput in most cases
+ ([#1024](https://github.com/Shopify/sarama/pull/1024)).
+ - Reuse the `time.Ticker` across fetch requests in the PartitionConsumer to
+ reduce CPU and memory usage when processing many partitions
+ ([#1028](https://github.com/Shopify/sarama/pull/1028)).
+ - Assign relative offsets to messages in the producer to save the brokers a
+ recompression pass
+ ([#1002](https://github.com/Shopify/sarama/pull/1002),
+ [#1015](https://github.com/Shopify/sarama/pull/1015)).
+
+Bug Fixes:
+ - Fix producing uncompressed batches with the new protocol format
+ ([#1032](https://github.com/Shopify/sarama/issues/1032)).
+ - Fix consuming compacted topics with the new protocol format
+ ([#1005](https://github.com/Shopify/sarama/issues/1005)).
+ - Fix consuming topics with a mix of protocol formats
+ ([#1021](https://github.com/Shopify/sarama/issues/1021)).
+ - Fix consuming when the broker includes multiple batches in a single response
+ ([#1022](https://github.com/Shopify/sarama/issues/1022)).
+ - Fix detection of `PartialTrailingMessage` when the partial message was
+ truncated before the magic value indicating its version
+ ([#1030](https://github.com/Shopify/sarama/pull/1030)).
+ - Fix expectation-checking in the mock of `SyncProducer.SendMessages`
+ ([#1035](https://github.com/Shopify/sarama/pull/1035)).
+
+#### Version 1.15.0 (2017-12-08)
+
+New Features:
+ - Claim official support for Kafka 1.0, though it did already work
+ ([#984](https://github.com/Shopify/sarama/pull/984)).
+ - Helper methods for Kafka version numbers to/from strings
+ ([#989](https://github.com/Shopify/sarama/pull/989)).
+ - Implement CreatePartitions request/response
+ ([#985](https://github.com/Shopify/sarama/pull/985)).
+
+Improvements:
+ - Add error codes 45-60
+ ([#986](https://github.com/Shopify/sarama/issues/986)).
+
+Bug Fixes:
+ - Fix slow consuming for certain Kafka 0.11/1.0 configurations
+ ([#982](https://github.com/Shopify/sarama/pull/982)).
+ - Correctly determine when a FetchResponse contains the new message format
+ ([#990](https://github.com/Shopify/sarama/pull/990)).
+ - Fix producing with multiple headers
+ ([#996](https://github.com/Shopify/sarama/pull/996)).
+ - Fix handling of truncated record batches
+ ([#998](https://github.com/Shopify/sarama/pull/998)).
+ - Fix leaking metrics when closing brokers
+ ([#991](https://github.com/Shopify/sarama/pull/991)).
+
+#### Version 1.14.0 (2017-11-13)
+
+New Features:
+ - Add support for the new Kafka 0.11 record-batch format, including the wire
+ protocol and the necessary behavioural changes in the producer and consumer.
+ Transactions and idempotency are not yet supported, but producing and
+ consuming should work with all the existing bells and whistles (batching,
+ compression, etc) as well as the new custom headers. Thanks to Vlad Hanciuta
+ of Arista Networks for this work. Part of
+ ([#901](https://github.com/Shopify/sarama/issues/901)).
+
+Bug Fixes:
+ - Fix encoding of ProduceResponse versions in test
+ ([#970](https://github.com/Shopify/sarama/pull/970)).
+ - Return partial replicas list when we have it
+ ([#975](https://github.com/Shopify/sarama/pull/975)).
+
+#### Version 1.13.0 (2017-10-04)
+
+New Features:
+ - Support for FetchRequest version 3
+ ([#905](https://github.com/Shopify/sarama/pull/905)).
+ - Permit setting version on mock FetchResponses
+ ([#939](https://github.com/Shopify/sarama/pull/939)).
+ - Add a configuration option to support storing only minimal metadata for
+ extremely large clusters
+ ([#937](https://github.com/Shopify/sarama/pull/937)).
+ - Add `PartitionOffsetManager.ResetOffset` for backtracking tracked offsets
+ ([#932](https://github.com/Shopify/sarama/pull/932)).
+
+Improvements:
+ - Provide the block-level timestamp when consuming compressed messages
+ ([#885](https://github.com/Shopify/sarama/issues/885)).
+ - `Client.Replicas` and `Client.InSyncReplicas` now respect the order returned
+ by the broker, which can be meaningful
+ ([#930](https://github.com/Shopify/sarama/pull/930)).
+ - Use a `Ticker` to reduce consumer timer overhead at the cost of higher
+ variance in the actual timeout
+ ([#933](https://github.com/Shopify/sarama/pull/933)).
+
+Bug Fixes:
+ - Gracefully handle messages with negative timestamps
+ ([#907](https://github.com/Shopify/sarama/pull/907)).
+ - Raise a proper error when encountering an unknown message version
+ ([#940](https://github.com/Shopify/sarama/pull/940)).
+
+#### Version 1.12.0 (2017-05-08)
+
+New Features:
+ - Added support for the `ApiVersions` request and response pair, and Kafka
+ version 0.10.2 ([#867](https://github.com/Shopify/sarama/pull/867)). Note
+ that you still need to specify the Kafka version in the Sarama configuration
+ for the time being.
+ - Added a `Brokers` method to the Client which returns the complete set of
+ active brokers ([#813](https://github.com/Shopify/sarama/pull/813)).
+ - Added an `InSyncReplicas` method to the Client which returns the set of all
+ in-sync broker IDs for the given partition, now that the Kafka versions for
+ which this was misleading are no longer in our supported set
+ ([#872](https://github.com/Shopify/sarama/pull/872)).
+ - Added a `NewCustomHashPartitioner` method which allows constructing a hash
+ partitioner with a custom hash method in case the default (FNV-1a) is not
+ suitable
+ ([#837](https://github.com/Shopify/sarama/pull/837),
+ [#841](https://github.com/Shopify/sarama/pull/841)).
+
+Improvements:
+ - Recognize more Kafka error codes
+ ([#859](https://github.com/Shopify/sarama/pull/859)).
+
+Bug Fixes:
+ - Fix an issue where decoding a malformed FetchRequest would not return the
+ correct error ([#818](https://github.com/Shopify/sarama/pull/818)).
+ - Respect ordering of group protocols in JoinGroupRequests. This fix is
+ transparent if you're using the `AddGroupProtocol` or
+ `AddGroupProtocolMetadata` helpers; otherwise you will need to switch from
+ the `GroupProtocols` field (now deprecated) to use `OrderedGroupProtocols`
+ ([#812](https://github.com/Shopify/sarama/issues/812)).
+ - Fix an alignment-related issue with atomics on 32-bit architectures
+ ([#859](https://github.com/Shopify/sarama/pull/859)).
+
+#### Version 1.11.0 (2016-12-20)
+
+_Important:_ As of Sarama 1.11 it is necessary to set the config value of
+`Producer.Return.Successes` to true in order to use the SyncProducer. Previous
+versions would silently override this value when instantiating a SyncProducer
+which led to unexpected values and data races.
+
+New Features:
+ - Metrics! Thanks to Sébastien Launay for all his work on this feature
+ ([#701](https://github.com/Shopify/sarama/pull/701),
+ [#746](https://github.com/Shopify/sarama/pull/746),
+ [#766](https://github.com/Shopify/sarama/pull/766)).
+ - Add support for LZ4 compression
+ ([#786](https://github.com/Shopify/sarama/pull/786)).
+ - Add support for ListOffsetRequest v1 and Kafka 0.10.1
+ ([#775](https://github.com/Shopify/sarama/pull/775)).
+ - Added a `HighWaterMarks` method to the Consumer which aggregates the
+ `HighWaterMarkOffset` values of its child topic/partitions
+ ([#769](https://github.com/Shopify/sarama/pull/769)).
+
+Bug Fixes:
+ - Fixed producing when using timestamps, compression and Kafka 0.10
+ ([#759](https://github.com/Shopify/sarama/pull/759)).
+ - Added missing decoder methods to DescribeGroups response
+ ([#756](https://github.com/Shopify/sarama/pull/756)).
+ - Fix producer shutdown when `Return.Errors` is disabled
+ ([#787](https://github.com/Shopify/sarama/pull/787)).
+ - Don't mutate configuration in SyncProducer
+ ([#790](https://github.com/Shopify/sarama/pull/790)).
+ - Fix crash on SASL initialization failure
+ ([#795](https://github.com/Shopify/sarama/pull/795)).
+
+#### Version 1.10.1 (2016-08-30)
+
+Bug Fixes:
+ - Fix the documentation for `HashPartitioner` which was incorrect
+ ([#717](https://github.com/Shopify/sarama/pull/717)).
+ - Permit client creation even when it is limited by ACLs
+ ([#722](https://github.com/Shopify/sarama/pull/722)).
+ - Several fixes to the consumer timer optimization code, regressions introduced
+ in v1.10.0. Go's timers are finicky
+ ([#730](https://github.com/Shopify/sarama/pull/730),
+ [#733](https://github.com/Shopify/sarama/pull/733),
+ [#734](https://github.com/Shopify/sarama/pull/734)).
+ - Handle consuming compressed relative offsets with Kafka 0.10
+ ([#735](https://github.com/Shopify/sarama/pull/735)).
+
+#### Version 1.10.0 (2016-08-02)
+
+_Important:_ As of Sarama 1.10 it is necessary to tell Sarama the version of
+Kafka you are running against (via the `config.Version` value) in order to use
+features that may not be compatible with old Kafka versions. If you don't
+specify this value it will default to 0.8.2 (the minimum supported), and trying
+to use more recent features (like the offset manager) will fail with an error.
+
+_Also:_ The offset-manager's behaviour has been changed to match the upstream
+java consumer (see [#705](https://github.com/Shopify/sarama/pull/705) and
+[#713](https://github.com/Shopify/sarama/pull/713)). If you use the
+offset-manager, please ensure that you are committing one *greater* than the
+last consumed message offset or else you may end up consuming duplicate
+messages.
+
+New Features:
+ - Support for Kafka 0.10
+ ([#672](https://github.com/Shopify/sarama/pull/672),
+ [#678](https://github.com/Shopify/sarama/pull/678),
+ [#681](https://github.com/Shopify/sarama/pull/681), and others).
+ - Support for configuring the target Kafka version
+ ([#676](https://github.com/Shopify/sarama/pull/676)).
+ - Batch producing support in the SyncProducer
+ ([#677](https://github.com/Shopify/sarama/pull/677)).
+ - Extend producer mock to allow setting expectations on message contents
+ ([#667](https://github.com/Shopify/sarama/pull/667)).
+
+Improvements:
+ - Support `nil` compressed messages for deleting in compacted topics
+ ([#634](https://github.com/Shopify/sarama/pull/634)).
+ - Pre-allocate decoding errors, greatly reducing heap usage and GC time against
+ misbehaving brokers ([#690](https://github.com/Shopify/sarama/pull/690)).
+ - Re-use consumer expiry timers, removing one allocation per consumed message
+ ([#707](https://github.com/Shopify/sarama/pull/707)).
+
+Bug Fixes:
+ - Actually default the client ID to "sarama" like we say we do
+ ([#664](https://github.com/Shopify/sarama/pull/664)).
+ - Fix a rare issue where `Client.Leader` could return the wrong error
+ ([#685](https://github.com/Shopify/sarama/pull/685)).
+ - Fix a possible tight loop in the consumer
+ ([#693](https://github.com/Shopify/sarama/pull/693)).
+ - Match upstream's offset-tracking behaviour
+ ([#705](https://github.com/Shopify/sarama/pull/705)).
+ - Report UnknownTopicOrPartition errors from the offset manager
+ ([#706](https://github.com/Shopify/sarama/pull/706)).
+ - Fix possible negative partition value from the HashPartitioner
+ ([#709](https://github.com/Shopify/sarama/pull/709)).
+
+#### Version 1.9.0 (2016-05-16)
+
+New Features:
+ - Add support for custom offset manager retention durations
+ ([#602](https://github.com/Shopify/sarama/pull/602)).
+ - Publish low-level mocks to enable testing of third-party producer/consumer
+ implementations ([#570](https://github.com/Shopify/sarama/pull/570)).
+ - Declare support for Golang 1.6
+ ([#611](https://github.com/Shopify/sarama/pull/611)).
+ - Support for SASL plain-text auth
+ ([#648](https://github.com/Shopify/sarama/pull/648)).
+
+Improvements:
+ - Simplified broker locking scheme slightly
+ ([#604](https://github.com/Shopify/sarama/pull/604)).
+ - Documentation cleanup
+ ([#605](https://github.com/Shopify/sarama/pull/605),
+ [#621](https://github.com/Shopify/sarama/pull/621),
+ [#654](https://github.com/Shopify/sarama/pull/654)).
+
+Bug Fixes:
+ - Fix race condition shutting down the OffsetManager
+ ([#658](https://github.com/Shopify/sarama/pull/658)).
+
+#### Version 1.8.0 (2016-02-01)
+
+New Features:
+ - Full support for Kafka 0.9:
+ - All protocol messages and fields
+ ([#586](https://github.com/Shopify/sarama/pull/586),
+ [#588](https://github.com/Shopify/sarama/pull/588),
+ [#590](https://github.com/Shopify/sarama/pull/590)).
+ - Verified that TLS support works
+ ([#581](https://github.com/Shopify/sarama/pull/581)).
+ - Fixed the OffsetManager compatibility
+ ([#585](https://github.com/Shopify/sarama/pull/585)).
+
+Improvements:
+ - Optimize for fewer system calls when reading from the network
+ ([#584](https://github.com/Shopify/sarama/pull/584)).
+ - Automatically retry `InvalidMessage` errors to match upstream behaviour
+ ([#589](https://github.com/Shopify/sarama/pull/589)).
+
+#### Version 1.7.0 (2015-12-11)
+
+New Features:
+ - Preliminary support for Kafka 0.9
+ ([#572](https://github.com/Shopify/sarama/pull/572)). This comes with several
+ caveats:
+ - Protocol-layer support is mostly in place
+ ([#577](https://github.com/Shopify/sarama/pull/577)), however Kafka 0.9
+ renamed some messages and fields, which we did not in order to preserve API
+ compatibility.
+ - The producer and consumer work against 0.9, but the offset manager does
+ not ([#573](https://github.com/Shopify/sarama/pull/573)).
+ - TLS support may or may not work
+ ([#581](https://github.com/Shopify/sarama/pull/581)).
+
+Improvements:
+ - Don't wait for request timeouts on dead brokers, greatly speeding recovery
+ when the TCP connection is left hanging
+ ([#548](https://github.com/Shopify/sarama/pull/548)).
+ - Refactored part of the producer. The new version provides a much more elegant
+ solution to [#449](https://github.com/Shopify/sarama/pull/449). It is also
+ slightly more efficient, and much more precise in calculating batch sizes
+ when compression is used
+ ([#549](https://github.com/Shopify/sarama/pull/549),
+ [#550](https://github.com/Shopify/sarama/pull/550),
+ [#551](https://github.com/Shopify/sarama/pull/551)).
+
+Bug Fixes:
+ - Fix race condition in consumer test mock
+ ([#553](https://github.com/Shopify/sarama/pull/553)).
+
+#### Version 1.6.1 (2015-09-25)
+
+Bug Fixes:
+ - Fix panic that could occur if a user-supplied message value failed to encode
+ ([#449](https://github.com/Shopify/sarama/pull/449)).
+
+#### Version 1.6.0 (2015-09-04)
+
+New Features:
+ - Implementation of a consumer offset manager using the APIs introduced in
+ Kafka 0.8.2. The API is designed mainly for integration into a future
+ high-level consumer, not for direct use, although it is *possible* to use it
+ directly.
+ ([#461](https://github.com/Shopify/sarama/pull/461)).
+
+Improvements:
+ - CRC32 calculation is much faster on machines with SSE4.2 instructions,
+ removing a major hotspot from most profiles
+ ([#255](https://github.com/Shopify/sarama/pull/255)).
+
+Bug Fixes:
+ - Make protocol decoding more robust against some malformed packets generated
+ by go-fuzz ([#523](https://github.com/Shopify/sarama/pull/523),
+ [#525](https://github.com/Shopify/sarama/pull/525)) or found in other ways
+ ([#528](https://github.com/Shopify/sarama/pull/528)).
+ - Fix a potential race condition panic in the consumer on shutdown
+ ([#529](https://github.com/Shopify/sarama/pull/529)).
+
+#### Version 1.5.0 (2015-08-17)
+
+New Features:
+ - TLS-encrypted network connections are now supported. This feature is subject
+ to change when Kafka releases built-in TLS support, but for now this is
+ enough to work with TLS-terminating proxies
+ ([#154](https://github.com/Shopify/sarama/pull/154)).
+
+Improvements:
+ - The consumer will not block if a single partition is not drained by the user;
+ all other partitions will continue to consume normally
+ ([#485](https://github.com/Shopify/sarama/pull/485)).
+ - Formatting of error strings has been much improved
+ ([#495](https://github.com/Shopify/sarama/pull/495)).
+ - Internal refactoring of the producer for code cleanliness and to enable
+ future work ([#300](https://github.com/Shopify/sarama/pull/300)).
+
+Bug Fixes:
+ - Fix a potential deadlock in the consumer on shutdown
+ ([#475](https://github.com/Shopify/sarama/pull/475)).
+
+#### Version 1.4.3 (2015-07-21)
+
+Bug Fixes:
+ - Don't include the partitioner in the producer's "fetch partitions"
+ circuit-breaker ([#466](https://github.com/Shopify/sarama/pull/466)).
+ - Don't retry messages until the broker is closed when abandoning a broker in
+ the producer ([#468](https://github.com/Shopify/sarama/pull/468)).
+ - Update the import path for snappy-go, it has moved again and the API has
+ changed slightly ([#486](https://github.com/Shopify/sarama/pull/486)).
+
+#### Version 1.4.2 (2015-05-27)
+
+Bug Fixes:
+ - Update the import path for snappy-go, it has moved from google code to github
+ ([#456](https://github.com/Shopify/sarama/pull/456)).
+
+#### Version 1.4.1 (2015-05-25)
+
+Improvements:
+ - Optimizations when decoding snappy messages, thanks to John Potocny
+ ([#446](https://github.com/Shopify/sarama/pull/446)).
+
+Bug Fixes:
+ - Fix hypothetical race conditions on producer shutdown
+ ([#450](https://github.com/Shopify/sarama/pull/450),
+ [#451](https://github.com/Shopify/sarama/pull/451)).
+
+#### Version 1.4.0 (2015-05-01)
+
+New Features:
+ - The consumer now implements `Topics()` and `Partitions()` methods to enable
+ users to dynamically choose what topics/partitions to consume without
+ instantiating a full client
+ ([#431](https://github.com/Shopify/sarama/pull/431)).
+ - The partition-consumer now exposes the high water mark offset value returned
+ by the broker via the `HighWaterMarkOffset()` method ([#339](https://github.com/Shopify/sarama/pull/339)).
+ - Added a `kafka-console-consumer` tool capable of handling multiple
+ partitions, and deprecated the now-obsolete `kafka-console-partitionConsumer`
+ ([#439](https://github.com/Shopify/sarama/pull/439),
+ [#442](https://github.com/Shopify/sarama/pull/442)).
+
+Improvements:
+ - The producer's logging during retry scenarios is more consistent, more
+ useful, and slightly less verbose
+ ([#429](https://github.com/Shopify/sarama/pull/429)).
+ - The client now shuffles its initial list of seed brokers in order to prevent
+ thundering herd on the first broker in the list
+ ([#441](https://github.com/Shopify/sarama/pull/441)).
+
+Bug Fixes:
+ - The producer now correctly manages its state if retries occur when it is
+ shutting down, fixing several instances of confusing behaviour and at least
+ one potential deadlock ([#419](https://github.com/Shopify/sarama/pull/419)).
+ - The consumer now handles messages for different partitions asynchronously,
+ making it much more resilient to specific user code ordering
+ ([#325](https://github.com/Shopify/sarama/pull/325)).
+
+#### Version 1.3.0 (2015-04-16)
+
+New Features:
+ - The client now tracks consumer group coordinators using
+ ConsumerMetadataRequests similar to how it tracks partition leadership using
+ regular MetadataRequests ([#411](https://github.com/Shopify/sarama/pull/411)).
+ This adds two methods to the client API:
+ - `Coordinator(consumerGroup string) (*Broker, error)`
+ - `RefreshCoordinator(consumerGroup string) error`
+
+Improvements:
+ - ConsumerMetadataResponses now automatically create a Broker object out of the
+ ID/address/port combination for the Coordinator; accessing the fields
+ individually has been deprecated
+ ([#413](https://github.com/Shopify/sarama/pull/413)).
+ - Much improved handling of `OffsetOutOfRange` errors in the consumer.
+ Consumers will fail to start if the provided offset is out of range
+ ([#418](https://github.com/Shopify/sarama/pull/418))
+ and they will automatically shut down if the offset falls out of range
+ ([#424](https://github.com/Shopify/sarama/pull/424)).
+ - Small performance improvement in encoding and decoding protocol messages
+ ([#427](https://github.com/Shopify/sarama/pull/427)).
+
+Bug Fixes:
+ - Fix a rare race condition in the client's background metadata refresher if
+ it happens to be activated while the client is being closed
+ ([#422](https://github.com/Shopify/sarama/pull/422)).
+
+#### Version 1.2.0 (2015-04-07)
+
+Improvements:
+ - The producer's behaviour when `Flush.Frequency` is set is now more intuitive
+ ([#389](https://github.com/Shopify/sarama/pull/389)).
+ - The producer is now somewhat more memory-efficient during and after retrying
+ messages due to an improved queue implementation
+ ([#396](https://github.com/Shopify/sarama/pull/396)).
+ - The consumer produces much more useful logging output when leadership
+ changes ([#385](https://github.com/Shopify/sarama/pull/385)).
+ - The client's `GetOffset` method will now automatically refresh metadata and
+ retry once in the event of stale information or similar
+ ([#394](https://github.com/Shopify/sarama/pull/394)).
+ - Broker connections now have support for using TCP keepalives
+ ([#407](https://github.com/Shopify/sarama/issues/407)).
+
+Bug Fixes:
+ - The OffsetCommitRequest message now correctly implements all three possible
+ API versions ([#390](https://github.com/Shopify/sarama/pull/390),
+ [#400](https://github.com/Shopify/sarama/pull/400)).
+
+#### Version 1.1.0 (2015-03-20)
+
+Improvements:
+ - Wrap the producer's partitioner call in a circuit-breaker so that repeatedly
+ broken topics don't choke throughput
+ ([#373](https://github.com/Shopify/sarama/pull/373)).
+
+Bug Fixes:
+ - Fix the producer's internal reference counting in certain unusual scenarios
+ ([#367](https://github.com/Shopify/sarama/pull/367)).
+ - Fix the consumer's internal reference counting in certain unusual scenarios
+ ([#369](https://github.com/Shopify/sarama/pull/369)).
+ - Fix a condition where the producer's internal control messages could have
+ gotten stuck ([#368](https://github.com/Shopify/sarama/pull/368)).
+ - Fix an issue where invalid partition lists would be cached when asking for
+ metadata for a non-existant topic ([#372](https://github.com/Shopify/sarama/pull/372)).
+
+
+#### Version 1.0.0 (2015-03-17)
+
+Version 1.0.0 is the first tagged version, and is almost a complete rewrite. The primary differences with previous untagged versions are:
+
+- The producer has been rewritten; there is now a `SyncProducer` with a blocking API, and an `AsyncProducer` that is non-blocking.
+- The consumer has been rewritten to only open one connection per broker instead of one connection per partition.
+- The main types of Sarama are now interfaces to make depedency injection easy; mock implementations for `Consumer`, `SyncProducer` and `AsyncProducer` are provided in the `github.com/Shopify/sarama/mocks` package.
+- For most uses cases, it is no longer necessary to open a `Client`; this will be done for you.

+======
+
+[](https://godoc.org/github.com/Shopify/sarama)
+[](https://travis-ci.org/Shopify/sarama)
+[](https://codecov.io/gh/Shopify/sarama)
+
+Sarama is an MIT-licensed Go client library for [Apache Kafka](https://kafka.apache.org/) version 0.8 (and later).
+
+### Getting started
+
+- API documentation and examples are available via [godoc](https://godoc.org/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
+
+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 1.8 through 1.11, and Kafka 1.0 through 2.0, 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).
+
+### Contributing
+
+* Get started by checking our [contribution guidelines](https://github.com/Shopify/sarama/blob/master/.github/CONTRIBUTING.md).
+* Read the [Sarama wiki](https://github.com/Shopify/sarama/wiki) for more
+ technical and design details.
+* The [Kafka Protocol Specification](https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol)
+ contains a wealth of useful information.
+* For more general issues, there is [a google group](https://groups.google.com/forum/#!forum/kafka-clients) for Kafka client developers.
+* If you have any questions, just ask!

+
+// PartitionConsumer processes Kafka messages from a given topic and partition. You MUST call one of Close() or
+// AsyncClose() on a PartitionConsumer to avoid leaks; it will not be garbage-collected automatically when it passes out
+// of scope.
+//
+// The simplest way of using a PartitionConsumer is to loop over its Messages channel using a for/range
+// loop. The PartitionConsumer will only stop itself in one case: when the offset being consumed is reported
+// as out of range by the brokers. In this case you should decide what you want to do (try a different offset,
+// notify a human, etc) and handle it appropriately. For all other error cases, it will just keep retrying.
+// By default, it logs these errors to sarama.Logger; if you want to be notified directly of all errors, set
+// your config's Consumer.Return.Errors to true and read from the Errors channel, using a select statement
+// or a separate goroutine. Check out the Consumer examples to see implementations of these different approaches.
+//
+// To terminate such a for/range loop while the loop is executing, call AsyncClose. This will kick off the process of
+// consumer tear-down & return imediately. Continue to loop, servicing the Messages channel until the teardown process
+// AsyncClose initiated closes it (thus terminating the for/range loop). If you've already ceased reading Messages, call
+// Close; this will signal the PartitionConsumer's goroutines to begin shutting down (just like AsyncClose), but will
+// also drain the Messages channel, harvest all errors & return them once cleanup has completed.

+ // should continue to service the 'Messages' and 'Errors' channels until they are empty. It is required to call this

+ // this before calling Close on the underlying client.
+ AsyncClose()

+ // Close stops the PartitionConsumer from fetching messages. It will initiate a shutdown just like AsyncClose, drain

+/*
+Package sarama is a pure Go client library for dealing with Apache Kafka (versions 0.8 and later). It includes a high-level
+API for easily producing and consuming messages, and a low-level API for controlling bytes on the wire when the high-level
+API is insufficient. Usage examples for the high-level APIs are provided inline with their full documentation.
+
+To produce messages, use either the AsyncProducer or the SyncProducer. The AsyncProducer accepts messages on a channel
+and produces them asynchronously in the background as efficiently as possible; it is preferred in most cases.
+The SyncProducer provides a method which will block until Kafka acknowledges the message as produced. This can be
+useful but comes with two caveats: it will generally be less efficient, and the actual durability guarantees
+depend on the configured value of `Producer.RequiredAcks`. There are configurations where a message acknowledged by the
+SyncProducer can still sometimes be lost.
+
+To consume messages, use the Consumer. Note that Sarama's Consumer implementation does not currently support automatic
+consumer-group rebalancing and offset tracking. For Zookeeper-based tracking (Kafka 0.8.2 and earlier), the
+https://github.com/wvanbergen/kafka library builds on Sarama to add this support. For Kafka-based tracking (Kafka 0.9
+and later), the https://github.com/bsm/sarama-cluster library builds on Sarama to add this support.
+
+For lower-level needs, the Broker and Request/Response objects permit precise control over each connection
+and message sent on the wire; the Client provides higher-level metadata management that is shared between
+the producers and the consumer. The Request/Response objects and properties are mostly undocumented, as they line up
+exactly with the protocol fields documented by Kafka at
+https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol
+
+Metrics are exposed through https://github.com/rcrowley/go-metrics library in a local registry.
+
+Broker related metrics:

+go-metrics
+==========
+
+This library provides a `metrics` package which can be used to instrument code,
+expose application metrics, and profile runtime performance in a flexible manner.
+
+Current API: [](https://godoc.org/github.com/armon/go-metrics)
+
+Sinks
+-----
+
+The `metrics` package makes use of a `MetricSink` interface to support delivery
+to any type of backend. Currently the following sinks are provided:
+
+* StatsiteSink : Sinks to a [statsite](https://github.com/armon/statsite/) instance (TCP)
+* StatsdSink: Sinks to a [StatsD](https://github.com/etsy/statsd/) / statsite instance (UDP)
+* PrometheusSink: Sinks to a [Prometheus](http://prometheus.io/) metrics endpoint (exposed via HTTP for scrapes)
+* InmemSink : Provides in-memory aggregation, can be used to export stats
+* FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example.
+* BlackholeSink : Sinks to nowhere
+
+In addition to the sinks, the `InmemSignal` can be used to catch a signal,
+and dump a formatted output of recent metrics. For example, when a process gets
+a SIGUSR1, it can dump to stderr recent performance metrics for debugging.
+
+Labels
+------
+
+Most metrics do have an equivalent ending with `WithLabels`, such methods
+allow to push metrics with labels and use some features of underlying Sinks
+(ex: translated into Prometheus labels).
+
+Since some of these labels may increase greatly cardinality of metrics, the
+library allow to filter labels using a blacklist/whitelist filtering system
+which is global to all metrics.
+
+* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default.
+* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks.
+
+By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that
+no tags are filetered at all, but it allow to a user to globally block some tags with high
+cardinality at application level.
+
+Examples
+--------
+
+Here is an example of using the package:
+
+```go
+func SlowMethod() {
+ // Profiling the runtime of a method
+ defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
+}
+
+// Configure a statsite sink as the global metrics sink
+sink, _ := metrics.NewStatsiteSink("statsite:8125")
+metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink)
+
+// Emit a Key/Value pair
+metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
+```
+
+Here is an example of setting up a signal handler:
+
+```go
+// Setup the inmem sink and signal handler
+inm := metrics.NewInmemSink(10*time.Second, time.Minute)
+sig := metrics.DefaultInmemSignal(inm)
+metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm)
+
+// Run some code
+inm.SetGauge([]string{"foo"}, 42)
+inm.EmitKey([]string{"bar"}, 30)
+
+inm.IncrCounter([]string{"baz"}, 42)
+inm.IncrCounter([]string{"baz"}, 1)
+inm.IncrCounter([]string{"baz"}, 80)
+
+inm.AddSample([]string{"method", "wow"}, 42)
+inm.AddSample([]string{"method", "wow"}, 100)
+inm.AddSample([]string{"method", "wow"}, 22)
+
+....
+```
+
+When a signal comes in, output like the following will be dumped to stderr:
+
+ [2014-01-28 14:57:33.04 -0800 PST][G] 'foo': 42.000
+ [2014-01-28 14:57:33.04 -0800 PST][P] 'bar': 30.000
+ [2014-01-28 14:57:33.04 -0800 PST][C] 'baz': Count: 3 Min: 1.000 Mean: 41.000 Max: 80.000 Stddev: 39.509
+ [2014-01-28 14:57:33.04 -0800 PST][S] 'method.wow': Count: 3 Min: 22.000 Mean: 54.667 Max: 100.000 Stddev: 40.513

+Cluster extensions for [Sarama](https://github.com/Shopify/sarama), the Go client library for Apache Kafka 0.9 (and later).
+
+## Documentation
+
+Documentation and example are available via godoc at http://godoc.org/github.com/bsm/sarama-cluster
+
+## Examples
+
+Consumers have two modes of operation. In the default multiplexed mode messages (and errors) of multiple
+topics and partitions are all passed to the single channel:
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+ "os"
+ "os/signal"
+
+ cluster "github.com/bsm/sarama-cluster"
+)
+
+func main() {
+
+ // init (custom) config, enable errors and notifications
+ config := cluster.NewConfig()
+ config.Consumer.Return.Errors = true
+ config.Group.Return.Notifications = true
+
+ // init consumer
+ brokers := []string{"127.0.0.1:9092"}
+ topics := []string{"my_topic", "other_topic"}
+ consumer, err := cluster.NewConsumer(brokers, "my-consumer-group", topics, config)
+ if err != nil {
+ panic(err)
+ }
+ defer consumer.Close()
+
+ // trap SIGINT to trigger a shutdown.
+ signals := make(chan os.Signal, 1)
+ signal.Notify(signals, os.Interrupt)
+
+ // consume errors
+ go func() {
+ for err := range consumer.Errors() {
+ log.Printf("Error: %s\n", err.Error())
+ }
+ }()
+
+ // consume notifications
+ go func() {
+ for ntf := range consumer.Notifications() {
+ log.Printf("Rebalanced: %+v\n", ntf)
+ }
+ }()
+
+ // consume messages, watch signals
+ for {
+ select {
+ case msg, ok := <-consumer.Messages():
+ if ok {
+ fmt.Fprintf(os.Stdout, "%s/%d/%d\t%s\t%s\n", msg.Topic, msg.Partition, msg.Offset, msg.Key, msg.Value)
+ consumer.MarkOffset(msg, "") // mark message as processed
+ }
+ case <-signals:
+ return
+ }
+ }
+}
+```
+
+Users who require access to individual partitions can use the partitioned mode which exposes access to partition-level
+consumers:
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+ "os"
+ "os/signal"
+
+ cluster "github.com/bsm/sarama-cluster"
+)
+
+func main() {
+
+ // init (custom) config, set mode to ConsumerModePartitions
+ config := cluster.NewConfig()
+ config.Group.Mode = cluster.ConsumerModePartitions
+
+ // init consumer
+ brokers := []string{"127.0.0.1:9092"}
+ topics := []string{"my_topic", "other_topic"}
+ consumer, err := cluster.NewConsumer(brokers, "my-consumer-group", topics, config)
+ if err != nil {
+ panic(err)
+ }
+ defer consumer.Close()
+
+ // trap SIGINT to trigger a shutdown.
+ signals := make(chan os.Signal, 1)
+ signal.Notify(signals, os.Interrupt)
+
+ // consume partitions
+ for {
+ select {
+ case part, ok := <-consumer.Partitions():
+ if !ok {
+ return
+ }
+
+ // start a separate goroutine to consume messages
+ go func(pc cluster.PartitionConsumer) {
+ for msg := range pc.Messages() {
+ fmt.Fprintf(os.Stdout, "%s/%d/%d\t%s\t%s\n", msg.Topic, msg.Partition, msg.Offset, msg.Key, msg.Value)
+ consumer.MarkOffset(msg, "") // mark message as processed
+ }
+ }(part)
+ case <-signals:
+ return
+ }
+ }
+}
+```
+
+## Running tests
+
+You need to install Ginkgo & Gomega to run tests. Please see
+http://onsi.github.io/ginkgo for more details.
+
+To run tests, call:
+
+ $ make test
+
+## Troubleshooting
+
+### Consumer not receiving any messages?
+
+By default, sarama's `Config.Consumer.Offsets.Initial` is set to `sarama.OffsetNewest`. This means that in the event that a brand new consumer is created, and it has never committed any offsets to kafka, it will only receive messages starting from the message after the current one that was written.
+
+If you wish to receive all messages (from the start of all messages in the topic) in the event that a consumer does not have any offsets committed to kafka, you need to set `Config.Consumer.Offsets.Initial` to `sarama.OffsetOldest`.

+# capnslog, the CoreOS logging package
+
+There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
+capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
+
+### Design Principles
+
+##### `package main` is the place where logging gets turned on and routed
+
+A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
+
+##### All log options are runtime-configurable.
+
+Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly.
+
+##### There is one log object per package. It is registered under its repository and package name.
+
+`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
+
+##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
+
+Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
+
+Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application.
+
+##### Log objects are an interface
+
+An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
+
+##### Log levels have specific meanings:
+
+ * Critical: Unrecoverable. Must fail.
+ * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
+ * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
+ * Notice: Normal, but important (uncommon) log information.
+ * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
+ * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
+ * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+ * Pointers are dereferenced and followed
+ * Circular data structures are detected and handled properly
+ * Custom Stringer/error interfaces are optionally invoked, including
+ on unexported types
+ * Custom types which only implement the Stringer/error interfaces via
+ a pointer receiver are optionally invoked when passing non-pointer
+ variables
+ * Byte arrays and slices are dumped like the hexdump -C command which
+ includes offsets, byte values in hex, and ASCII output (only when using
+ Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+ * Dump style which prints with newlines, customizable indentation,
+ and additional debug information such as types and all pointer addresses
+ used to indirect to the final value
+ * A custom Formatter interface that integrates cleanly with the standard fmt
+ package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+ similar to the default %v while providing the additional functionality
+ outlined above and passing unsupported format verbs such as %x and %q
+ along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew. See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+ spew.Dump(myVar1, myVar2, ...)
+ spew.Fdump(someWriter, myVar1, myVar2, ...)
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+The following configuration options are available:
+ * Indent
+ String to use for each indentation level for Dump functions.
+ It is a single space by default. A popular alternative is "\t".
+
+ * MaxDepth
+ Maximum number of levels to descend into nested data structures.
+ There is no limit by default.
+
+ * DisableMethods
+ Disables invocation of error and Stringer interface methods.
+ Method invocation is enabled by default.
+
+ * DisablePointerMethods
+ Disables invocation of error and Stringer interface methods on types
+ which only accept pointer receivers from non-pointer variables.
+ Pointer method invocation is enabled by default.
+
+ * DisablePointerAddresses
+ DisablePointerAddresses specifies whether to disable the printing of
+ pointer addresses. This is useful when diffing data structures in tests.
+
+ * DisableCapacities
+ DisableCapacities specifies whether to disable the printing of
+ capacities for arrays, slices, maps and channels. This is useful when
+ diffing data structures in tests.
+
+ * ContinueOnMethod
+ Enables recursion into types after invoking error and Stringer interface
+ methods. Recursion after method invocation is disabled by default.
+
+ * SortKeys
+ Specifies map keys should be sorted before being printed. Use
+ this to have a more deterministic, diffable output. Note that
+ only native types (bool, int, uint, floats, uintptr and string)
+ and types which implement error or Stringer interfaces are
+ supported with other types sorted according to the
+ reflect.Value.String() output which guarantees display
+ stability. Natural map order is used by default.
+
+ * SpewKeys
+ Specifies that, as a last resort attempt, map keys should be
+ spewed to strings and sorted by those strings. This is only
+ considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+ spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer. For example, to dump to standard error:
+
+ spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+ str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+ (main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+ flag: (main.Flag) flagTwo,
+ data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) (len=1) {
+ (string) (len=3) "one": (bool) true
+ }
+ }
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+ ([]uint8) (len=32 cap=32) {
+ 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
+ 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
+ 00000020 31 32 |12|
+ }
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations. Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting. In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
+functions have syntax you are most likely already familiar with:
+
+ spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+ spew.Println(myVar, myVar2)
+ spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+ spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+ %v: <**>5
+ %+v: <**>(0xf8400420d0->0xf8400420c8)5
+ %#v: (**uint8)5
+ %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+ %v: <*>{1 <*><shown>}
+ %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+ %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+ %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output. Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+
+Xerial-compatible Snappy framing support for golang.
+
+Packages using Xerial for snappy encoding use a framing format incompatible with
+basically everything else in existence. This package wraps Go's built-in snappy
+package to support it.
+
+Apps that use this format include Apache Kafka (see
+https://github.com/dpkp/kafka-python/issues/126#issuecomment-35478921 for
+details).

+A fast Golang queue using a ring-buffer, based on the version suggested by Dariusz Górecki.
+Using this instead of other, simpler, queue implementations (slice+append or linked list) provides
+substantial memory and time benefits, and fewer GC pauses.
+
+The queue implemented here is as fast as it is in part because it is *not* thread-safe.
+
+Follows semantic versioning using https://gopkg.in/ - import from
+[`gopkg.in/eapache/queue.v1`](https://gopkg.in/eapache/queue.v1)

+A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
+You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
+Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
+
+ - nullable, if false, a field is generated without a pointer (see warning below).
+ - embed, if true, the field is generated as an embedded field.
+ - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
+ - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
+ - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
+ - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+ - castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+
+Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
+
+Let us look at:
+
+ github.com/gogo/protobuf/test/example/example.proto
+
+for a quicker overview.
+
+The following message:
+
+ package test;
+
+ import "github.com/gogo/protobuf/gogoproto/gogo.proto";
+
+ message A {
+ optional string Description = 1 [(gogoproto.nullable) = false];
+ optional int64 Number = 2 [(gogoproto.nullable) = false];
+ optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
+ }
+
+Will generate a go struct which looks a lot like this:
+
+ type A struct {
+ Description string
+ Number int64
+ Id github_com_gogo_protobuf_test_custom.Uuid
+ }
+
+You will see there are no pointers, since all fields are non-nullable.
+You will also see a custom type which marshals to a string.
+Be warned it is your responsibility to test your custom types thoroughly.
+You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
+
+Next we will embed the message A in message B.
+
+ message B {
+ optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
+ repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
+ }
+
+See below that A is embedded in B.
+
+ type B struct {
+ A
+ G []github_com_gogo_protobuf_test_custom.Uint128
+ }
+
+Also see the repeated custom type.
+
+ type Uint128 [2]uint64
+
+Next we will create a custom name for one of our fields.
+
+ message C {
+ optional int64 size = 1 [(gogoproto.customname) = "MySize"];
+ }
+
+See below that the field's name is MySize and not Size.
+
+ type C struct {
+ MySize *int64
+ }
+
+The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
+As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
+Using customname you can fix this error without changing the field name.
+This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
+
+Gogoprotobuf also has some more subtle changes, these could be changed back:
+
+ - the generated package name for imports do not have the extra /filename.pb,
+ but are actually the imports specified in the .proto file.
+
+Gogoprotobuf also has lost some features which should be brought back with time:
+
+ - Marshalling and unmarshalling with reflect and without the unsafe package,
+ this requires work in pointer_reflect.go
+
+Why does nullable break protocol buffer specifications:
+
+The protocol buffer specification states, somewhere, that you should be able to tell whether a
+field is set or unset. With the option nullable=false this feature is lost,
+since your non-nullable fields will always be set. It can be seen as a layer on top of
+protocol buffers, where before and after marshalling all non-nullable fields are set
+and they cannot be unset.
+
+Goprotobuf Compatibility:
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
+Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
+The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
+
+ - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
+ - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
+ - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
+ - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
+ - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
+ - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
+ - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
+ - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
+
+Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
+
+ - github.com/gogo/protobuf/plugin/<extension_name>
+
+If you do not use any of these extension the code that is generated
+will be the same as if goprotobuf has generated it.
+
+The most complete way to see examples is to look at
+
+ github.com/gogo/protobuf/test/thetest.proto
+
+Gogoprototest is a seperate project,
+because we want to keep gogoprotobuf independent of goprotobuf,
+but we still want to test it thoroughly.

+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];

+ // For example, say we have a file like:

+ // }
+ // Let's look at just the field definition:
+ // optional string foo = 1;
+ // ^ ^^ ^^ ^ ^^^

+ // [a,b) [ 4, 0, 2, 0, 4 ] The label (optional).

+ // [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.

+ - 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,

+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;

+ // 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

+ // 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.

+ // ignore those that it doesn't understand, as more types of locations could

+// Options
+
+// Each of the definitions above may have "options" attached. These are

+// 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:

+// If this turns out to be popular, a web service will be set up

+ // 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.

+ // 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.

+// Protobuf library provides support to pack/unpack Any values in the form

+//
+// Example 1: Pack and unpack a message in C++.
+//
+// Foo foo = ...;

+// 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;

+// }
+//
+// {
+// "@type": "type.googleapis.com/google.profile.Person",

+// }
+//
+// 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

+// # 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

+// Package snappy implements the Snappy compression format. It aims for very
+// high speeds and reasonable compression.
+//
+// There are actually two Snappy formats: block and stream. They are related,
+// but different: trying to decompress block-compressed data as a Snappy stream
+// will fail, and vice versa. The block format is the Decode and Encode
+// functions and the stream format is the Reader and Writer types.
+//
+// The block format, the more common case, is used when the complete size (the
+// number of bytes) of the original data is known upfront, at the time
+// compression starts. The stream format, also known as the framing format, is
+// for when that isn't always true.
+//
+// The canonical, C++ implementation is at https://github.com/google/snappy and
+// it only implements the block format.
+package snappy // import "github.com/golang/snappy"

+import (
+ "hash/crc32"

+
+/*
+Each encoded block begins with the varint-encoded length of the decoded data,
+followed by a sequence of chunks. Chunks begin and end on byte boundaries. The
+first byte of each chunk is broken into its 2 least and 6 most significant bits
+called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag.
+Zero means a literal tag. All other values mean a copy tag.
+
+For literal tags:
+ - If m < 60, the next 1 + m bytes are literal bytes.
+ - Otherwise, let n be the little-endian unsigned integer denoted by the next
+ m - 59 bytes. The next 1 + n bytes after that are literal bytes.
+
+For copy tags, length bytes are copied from offset bytes ago, in the style of
+Lempel-Ziv compression algorithms. In particular:
+ - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
+ The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
+ of the offset. The next byte is bits 0-7 of the offset.
+ - For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
+ The length is 1 + m. The offset is the little-endian unsigned integer
+ denoted by the next 2 bytes.
+ - For l == 3, this tag is a legacy format that is no longer issued by most
+ encoders. Nonetheless, the offset ranges in [0, 1<<32) and the length in
+ [1, 65). The length is 1 + m. The offset is the little-endian unsigned
+ integer denoted by the next 4 bytes.

+# uuid 
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services.
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid). It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice. One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).

+
+ Each Contributor hereby grants You a world-wide, royalty-free,
+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ The licenses granted in Section 2.1 with respect to any Contribution become
+ effective for each Contribution on the date the Contributor first distributes
+ such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under this
+ License. No additional rights or licenses will be implied from the distribution
+ or licensing of Covered Software under this License. Notwithstanding Section
+ 2.1(b) above, no patent license is granted by a Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party’s
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of its
+ Contributions.
+
+ This License does not grant any rights in the trademarks, service marks, or
+ logos of any Contributor (except as may be necessary to comply with the
+ notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this License
+ (see Section 10.2) or under the terms of a Secondary License (if permitted
+ under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its Contributions
+ are its original creation(s) or it has sufficient rights to grant the
+ rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under applicable
+ copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under the
+ terms of this License. You must inform recipients that the Source Code Form
+ of the Covered Software is governed by the terms of this License, and how
+ they can obtain a copy of this License. You may not attempt to alter or
+ restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this License,
+ or sublicense it under different terms, provided that the license for
+ the Executable Form does not attempt to limit or alter the recipients’
+ rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for the
+ Covered Software. If the Larger Work is a combination of Covered Software
+ with a work governed by one or more Secondary Licenses, and the Covered
+ Software is not Incompatible With Secondary Licenses, this License permits
+ You to additionally distribute such Covered Software under the terms of
+ such Secondary License(s), so that the recipient of the Larger Work may, at
+ their option, further distribute the Covered Software under the terms of
+ either this License or such Secondary License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices (including
+ copyright notices, patent notices, disclaimers of warranty, or limitations
+ of liability) contained within the Source Code Form of the Covered
+ Software, except that You may alter any license notices to the extent
+ required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on behalf
+ of any Contributor. You must make it absolutely clear that any such
+ warranty, support, indemnity, or liability obligation is offered by You
+ alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute, judicial
+ order, or regulation then You must: (a) comply with the terms of this License
+ to the maximum extent possible; and (b) describe the limitations and the code
+ they affect. Such description must be placed in a text file included with all
+ distributions of the Covered Software under this License. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+ if such Contributor fails to notify You of the non-compliance by some
+ reasonable means prior to 60 days after You have come back into compliance.
+ Moreover, Your grants from a particular Contributor are reinstated on an
+ ongoing basis if such Contributor notifies You of the non-compliance by
+ some reasonable means, this is the first time You have received notice of
+ non-compliance with this License from such Contributor, and You become
+ compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions, counter-claims,
+ and cross-claims) alleging that a Contributor Version directly or
+ indirectly infringes any patent, then the rights granted to You by any and
+ all Contributors for the Covered Software under Section 2.1 of this License
+ shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an “as is” basis, without
+ warranty of any kind, either expressed, implied, or statutory, including,
+ without limitation, warranties that the Covered Software is free of defects,
+ merchantable, fit for a particular purpose or non-infringing. The entire
+ risk as to the quality and performance of the Covered Software is with You.
+ Should any Covered Software prove defective in any respect, You (not any
+ Contributor) assume the cost of any necessary servicing, repair, or
+ correction. This disclaimer of warranty constitutes an essential part of this
+ License. No use of any Covered Software is authorized under this License
+ except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from such
+ party’s negligence to the extent applicable law prohibits such limitation.
+ Some jurisdictions do not allow the exclusion or limitation of incidental or
+ consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts of
+ a jurisdiction where the defendant maintains its principal place of business
+ and such litigation shall be governed by laws of that jurisdiction, without
+ reference to its conflict-of-law provisions. Nothing in this Section shall
+ prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject matter
+ hereof. If any provision of this License is held to be unenforceable, such
+ provision shall be reformed only to the extent necessary to make it
+ enforceable. Any law or regulation which provides that the language of a
+ contract shall be construed against the drafter shall not be used to construe
+ this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version of
+ the License under which You originally received the Covered Software, or
+ under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a modified
+ version of this License if you rename the license and remove any
+ references to the name of the license steward (except to note that such
+ modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
+ If You choose to distribute Source Code Form that is Incompatible With
+ Secondary Licenses under the terms of this version of the License, the
+ notice described in Exhibit B of this License must be attached.

+Consul API client
+=================
+
+This package provides the `api` package which attempts to
+provide programmatic access to the full Consul API.
+
+Currently, all of the Consul APIs included in version 0.6.0 are supported.
+
+Documentation
+=============
+
+The full documentation is available on [Godoc](https://godoc.org/github.com/hashicorp/consul/api)
+
+Usage
+=====
+
+Below is an example of using the Consul client:
+
+```go
+package main
+
+import "github.com/hashicorp/consul/api"
+import "fmt"
+
+func main() {
+ // Get a new client
+ client, err := api.NewClient(api.DefaultConfig())
+ if err != nil {
+ panic(err)
+ }
+
+ // Get a handle to the KV API
+ kv := client.KV()
+
+ // PUT a new KV pair
+ p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
+ _, err = kv.Put(p, nil)
+ if err != nil {
+ panic(err)
+ }
+
+ // Lookup the pair
+ pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
+ if err != nil {
+ panic(err)
+ }
+ fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
+}
+```
+
+To run this example, start a Consul server:
+
+```bash
+consul agent -dev
+```
+
+Copy the code above into a file such as `main.go`.
+
+Install and run. You'll see a key (`REDIS_MAXCLIENTS`) and value (`1000`) printed.
+
+```bash
+$ go get
+$ go run main.go
+KV: REDIS_MAXCLIENTS 1000
+```
+
+After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv

+Command: `consul license`
+
+<%= enterprise_alert :consul %>
+
+The `license` command provides datacenter-level management of the Consul Enterprise license. This was added in Consul 1.1.0.
+
+If ACLs are enabled then a token with operator privileges may be required in
+order to use this command. Requests are forwarded internally to the leader
+if required, so this can be run from any Consul node in a cluster. See the
+[ACL Guide](/docs/guides/acl.html#operator) for more information.
+
+
+```text
+Usage: consul license <subcommand> [options] [args]
+
+ This command has subcommands for managing the Consul Enterprise license
+ Here are some simple examples, and more detailed examples are
+ available in the subcommands or the documentation.
+
+ Install a new license from a file:
+
+ $ consul license put @consul.license
+
+ Install a new license from stdin:
+
+ $ consul license put -
+
+ Install a new license from a string:
+
+ $ consul license put "<license blob>"
+
+ Retrieve the current license:
+
+ $ consul license get
+
+ For more examples, ask for subcommand help or view the documentation.
+
+Subcommands:
+ get Get the current license
+ put Puts a new license in the datacenter
+```
+
+## put
+

+ distribute the Covered Software under a subsequent version of this
+ License (see Section 10.2) or under the terms of a Secondary License (if
+ permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its
+ Contributions are its original creation(s) or it has sufficient rights to
+ grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under
+ applicable copyright doctrines of fair use, fair dealing, or other
+ equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under
+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version
+ of the License under which You originally received the Covered Software,
+ or under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a
+ modified version of this License if you rename the license and remove
+ any references to the name of the license steward (except to note that
+ such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+ Licenses If You choose to distribute Source Code Form that is
+ Incompatible With Secondary Licenses under the terms of this version of
+ the License, the notice described in Exhibit B of this License must be

+
+Functions for accessing "clean" Go http.Client values
+
+-------------
+
+The Go standard library contains a default `http.Client` called
+`http.DefaultClient`. It is a common idiom in Go code to start with
+`http.DefaultClient` and tweak it as necessary, and in fact, this is
+encouraged; from the `http` package documentation:
+
+> The Client's Transport typically has internal state (cached TCP connections),
+so Clients should be reused instead of created as needed. Clients are safe for
+concurrent use by multiple goroutines.
+
+Unfortunately, this is a shared value, and it is not uncommon for libraries to
+assume that they are free to modify it at will. With enough dependencies, it
+can be very easy to encounter strange problems and race conditions due to
+manipulation of this shared value across libraries and goroutines (clients are
+safe for concurrent use, but writing values to the client struct itself is not
+protected).
+
+Making things worse is the fact that a bare `http.Client` will use a default
+`http.Transport` called `http.DefaultTransport`, which is another global value
+that behaves the same way. So it is not simply enough to replace
+`http.DefaultClient` with `&http.Client{}`.
+
+This repository provides some simple functions to get a "clean" `http.Client`
+-- one that uses the same default values as the Go standard library, but
+returns a client that does not share any state with other clients.

+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+

+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have

+go-immutable-radix [](https://travis-ci.org/hashicorp/go-immutable-radix)
+=========
+
+Provides the `iradix` package that implements an immutable [radix tree](http://en.wikipedia.org/wiki/Radix_tree).
+The package only provides a single `Tree` implementation, optimized for sparse nodes.
+
+As a radix tree, it provides the following:
+ * O(k) operations. In many cases, this can be faster than a hash table since
+ the hash function is an O(k) operation, and hash tables have very poor cache locality.
+ * Minimum / Maximum value lookups
+ * Ordered iteration
+
+A tree supports using a transaction to batch multiple updates (insert, delete)
+in a more efficient manner than performing each operation one at a time.
+
+For a mutable variant, see [go-radix](https://github.com/armon/go-radix).
+
+Documentation
+=============
+
+The full documentation is available on [Godoc](http://godoc.org/github.com/hashicorp/go-immutable-radix).
+
+Example
+=======
+
+Below is a simple example of usage
+
+```go
+// Create a tree
+r := iradix.New()
+r, _, _ = r.Insert([]byte("foo"), 1)
+r, _, _ = r.Insert([]byte("bar"), 2)
+r, _, _ = r.Insert([]byte("foobar"), 2)
+
+// Find the longest prefix match
+m, _, _ := r.Root().LongestPrefix([]byte("foozip"))
+if string(m) != "foo" {
+ panic("should be foo")
+}
+```

+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent

+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a

+# rootcerts
+
+Functions for loading root certificates for TLS connections.
+
+-----
+
+Go's standard library `crypto/tls` provides a common mechanism for configuring
+TLS connections in `tls.Config`. The `RootCAs` field on this struct is a pool
+of certificates for the client to use as a trust store when verifying server
+certificates.
+
+This library contains utility functions for loading certificates destined for
+that field, as well as one other important thing:
+
+When the `RootCAs` field is `nil`, the standard library attempts to load the
+host's root CA set. This behavior is OS-specific, and the Darwin
+implementation contains [a bug that prevents trusted certificates from the
+System and Login keychains from being loaded][1]. This library contains
+Darwin-specific behavior that works around that bug.
+
+[1]: https://github.com/golang/go/issues/14514
+
+## Example Usage
+
+Here's a snippet demonstrating how this library is meant to be used:
+
+```go
+func httpClient() (*http.Client, error)
+ tlsConfig := &tls.Config{}
+ err := rootcerts.ConfigureTLS(tlsConfig, &rootcerts.Config{
+ CAFile: os.Getenv("MYAPP_CAFILE"),
+ CAPath: os.Getenv("MYAPP_CAPATH"),
+ })
+ if err != nil {
+ return nil, err
+ }
+ c := cleanhttp.DefaultClient()
+ t := cleanhttp.DefaultTransport()
+ t.TLSClientConfig = tlsConfig
+ c.Transport = t
+ return c, nil
+}
+```

+ the terms of this License. You must inform recipients that the Source
+ Code Form of the Covered Software is governed by the terms of this
+ License, and how they can obtain a copy of this License. You may not
+ attempt to alter or restrict the recipients' rights in the Source Code
+ Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the

+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this
+ License, or sublicense it under different terms, provided that the
+ license for the Executable Form does not attempt to limit or alter the
+ recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for
+ the Covered Software. If the Larger Work is a combination of Covered
+ Software with a work governed by one or more Secondary Licenses, and the
+ Covered Software is not Incompatible With Secondary Licenses, this
+ License permits You to additionally distribute such Covered Software
+ under the terms of such Secondary License(s), so that the recipient of
+ the Larger Work may, at their option, further distribute the Covered
+ Software under the terms of either this License or such Secondary
+ License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices
+ (including copyright notices, patent notices, disclaimers of warranty, or
+ limitations of liability) contained within the Source Code Form of the
+ Covered Software, except that You may alter any license notices to the
+ extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on
+ behalf of any Contributor. You must make it absolutely clear that any
+ such warranty, support, indemnity, or liability obligation is offered by
+ You alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute,
+ judicial order, or regulation then You must: (a) comply with the terms of
+ this License to the maximum extent possible; and (b) describe the
+ limitations and the code they affect. Such description must be placed in a
+ text file included with all distributions of the Covered Software under
+ this License. Except to the extent prohibited by statute or regulation,
+ such description must be sufficiently detailed for a recipient of ordinary
+ skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing
+ basis, if such Contributor fails to notify You of the non-compliance by
+ some reasonable means prior to 60 days after You have come back into
+ compliance. Moreover, Your grants from a particular Contributor are
+ reinstated on an ongoing basis if such Contributor notifies You of the
+ non-compliance by some reasonable means, this is the first time You have
+ received notice of non-compliance with this License from such
+ Contributor, and You become compliant prior to 30 days after Your receipt
+ of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions,
+ counter-claims, and cross-claims) alleging that a Contributor Version
+ directly or indirectly infringes any patent, then the rights granted to
+ You by any and all Contributors for the Covered Software under Section
+ 2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an "as is" basis,
+ without warranty of any kind, either expressed, implied, or statutory,
+ including, without limitation, warranties that the Covered Software is free
+ of defects, merchantable, fit for a particular purpose or non-infringing.
+ The entire risk as to the quality and performance of the Covered Software
+ is with You. Should any Covered Software prove defective in any respect,
+ You (not any Contributor) assume the cost of any necessary servicing,
+ repair, or correction. This disclaimer of warranty constitutes an essential
+ part of this License. No use of any Covered Software is authorized under
+ this License except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from
+ such party's negligence to the extent applicable law prohibits such
+ limitation. Some jurisdictions do not allow the exclusion or limitation of
+ incidental or consequential damages, so this exclusion and limitation may
+ not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts
+ of a jurisdiction where the defendant maintains its principal place of
+ business and such litigation shall be governed by laws of that
+ jurisdiction, without reference to its conflict-of-law provisions. Nothing
+ in this Section shall prevent a party's ability to bring cross-claims or
+ counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject
+ matter hereof. If any provision of this License is held to be
+ unenforceable, such provision shall be reformed only to the extent
+ necessary to make it enforceable. Any law or regulation which provides that
+ the language of a contract shall be construed against the drafter shall not
+ be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version
+ of the License under which You originally received the Covered Software,
+ or under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a
+ modified version of this License if you rename the license and remove
+ any references to the name of the license steward (except to note that
+ such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+ Licenses If You choose to distribute Source Code Form that is
+ Incompatible With Secondary Licenses under the terms of this version of
+ the License, the notice described in Exhibit B of this License must be

+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ effective for each Contribution on the date the Contributor first distributes
+ such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under this
+ License. No additional rights or licenses will be implied from the distribution
+ or licensing of Covered Software under this License. Notwithstanding Section
+ 2.1(b) above, no patent license is granted by a Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party’s
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of its
+ Contributions.
+
+ This License does not grant any rights in the trademarks, service marks, or
+ logos of any Contributor (except as may be necessary to comply with the
+ notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this License
+ (see Section 10.2) or under the terms of a Secondary License (if permitted
+ under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its Contributions
+ are its original creation(s) or it has sufficient rights to grant the
+ rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under applicable
+ copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under the
+ terms of this License. You must inform recipients that the Source Code Form
+ of the Covered Software is governed by the terms of this License, and how
+ they can obtain a copy of this License. You may not attempt to alter or
+ restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this License,
+ or sublicense it under different terms, provided that the license for
+ the Executable Form does not attempt to limit or alter the recipients’
+ rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for the
+ Covered Software. If the Larger Work is a combination of Covered Software
+ with a work governed by one or more Secondary Licenses, and the Covered
+ Software is not Incompatible With Secondary Licenses, this License permits
+ You to additionally distribute such Covered Software under the terms of
+ such Secondary License(s), so that the recipient of the Larger Work may, at
+ their option, further distribute the Covered Software under the terms of
+ either this License or such Secondary License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices (including
+ copyright notices, patent notices, disclaimers of warranty, or limitations
+ of liability) contained within the Source Code Form of the Covered
+ Software, except that You may alter any license notices to the extent
+ required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on behalf
+ of any Contributor. You must make it absolutely clear that any such
+ warranty, support, indemnity, or liability obligation is offered by You
+ alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute, judicial
+ order, or regulation then You must: (a) comply with the terms of this License
+ to the maximum extent possible; and (b) describe the limitations and the code
+ they affect. Such description must be placed in a text file included with all
+ distributions of the Covered Software under this License. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+ if such Contributor fails to notify You of the non-compliance by some
+ reasonable means prior to 60 days after You have come back into compliance.
+ Moreover, Your grants from a particular Contributor are reinstated on an
+ ongoing basis if such Contributor notifies You of the non-compliance by
+ some reasonable means, this is the first time You have received notice of
+ non-compliance with this License from such Contributor, and You become
+ compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions, counter-claims,
+ and cross-claims) alleging that a Contributor Version directly or
+ indirectly infringes any patent, then the rights granted to You by any and
+ all Contributors for the Covered Software under Section 2.1 of this License
+ shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an “as is” basis, without
+ warranty of any kind, either expressed, implied, or statutory, including,
+ without limitation, warranties that the Covered Software is free of defects,
+ merchantable, fit for a particular purpose or non-infringing. The entire
+ risk as to the quality and performance of the Covered Software is with You.
+ Should any Covered Software prove defective in any respect, You (not any
+ Contributor) assume the cost of any necessary servicing, repair, or
+ correction. This disclaimer of warranty constitutes an essential part of this
+ License. No use of any Covered Software is authorized under this License
+ except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from such
+ party’s negligence to the extent applicable law prohibits such limitation.
+ Some jurisdictions do not allow the exclusion or limitation of incidental or
+ consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts of
+ a jurisdiction where the defendant maintains its principal place of business
+ and such litigation shall be governed by laws of that jurisdiction, without
+ reference to its conflict-of-law provisions. Nothing in this Section shall
+ prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject matter
+ hereof. If any provision of this License is held to be unenforceable, such
+ provision shall be reformed only to the extent necessary to make it
+ enforceable. Any law or regulation which provides that the language of a
+ contract shall be construed against the drafter shall not be used to construe
+ this License against a Contributor.
+
+

+# go-homedir
+
+This is a Go library for detecting the user's home directory without
+the use of cgo, so the library can be used in cross-compilation environments.
+
+Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
+for a user, and `homedir.Expand()` to expand the `~` in a path to the home
+directory.
+
+**Why not just use `os/user`?** The built-in `os/user` package requires
+cgo on Darwin systems. This means that any Go code that uses that package
+cannot cross compile. But 99% of the time the use for `os/user` is just to
+retrieve the home directory, which we can do for the current user without
+cgo. This library does that, enabling cross-compilation.

+# mapstructure [](https://godoc.org/github.com/mitchellh/mapstructure)
+
+mapstructure is a Go library for decoding generic map values to structures
+and vice versa, while providing helpful error handling.
+
+This library is most useful when decoding values from some data stream (JSON,
+Gob, etc.) where you don't _quite_ know the structure of the underlying data
+until you read a part of it. You can therefore read a `map[string]interface{}`
+and use this library to decode it into the proper underlying native Go
+structure.
+
+## Installation
+
+Standard `go get`:
+
+```
+$ go get github.com/mitchellh/mapstructure
+```
+
+## Usage & Example
+
+For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
+
+The `Decode` function has examples associated with it there.
+
+## But Why?!
+
+Go offers fantastic standard libraries for decoding formats such as JSON.
+The standard method is to have a struct pre-created, and populate that struct
+from the bytes of the encoded format. This is great, but the problem is if
+you have configuration or an encoding that changes slightly depending on
+specific fields. For example, consider this JSON:
+
+```json
+{
+ "type": "person",
+ "name": "Mitchell"
+}
+```
+
+Perhaps we can't populate a specific structure without first reading
+the "type" field from the JSON. We could always do two passes over the
+decoding of the JSON (reading the "type" first, and the rest later).
+However, it is much simpler to just decode this into a `map[string]interface{}`
+structure, read the "type" key, then use something like this library
+to decode it into the proper structure.

+## How to Build and Run a Voltha Go language Adapter
+
+This directory is a repo for all voltha adapters written in Go language. At this time, the simulated_olt and
+simulated_onu adapters are the only adapters using the Go language. These adapters provide basic capabilities
+which will be used for high availability and capacity testing.
+
+### Building and running the Simulated OLT and ONU Adapters
+
+Please refer to the ```BUILD.md``` file under the voltha-go repo

+//Package log provides a structured Logger interface implemented using zap logger. It provides the following capabilities:
+//1. Package level logging - a go package can register itself (AddPackage) and have a logger created for that package.
+//2. Dynamic log level change - for all registered packages (SetAllLogLevel)
+//3. Dynamic log level change - for a given package (SetPackageLogLevel)
+//4. Provides a default logger for unregistered packages
+//5. Allow key-value pairs to be added to a logger(UpdateLogger) or all loggers (UpdateAllLoggers) at run time
+//6. Add to the log output the location where the log was invoked (filename.functionname.linenumber)
+//
+// Using package-level logging (recommended approach). In the examples below, log refers to this log package.
+// 1. In the appropriate package add the following in the init section of the package. The log level can be changed
+// and any number of default fields can be added as well. The log level specifies the lowest log level that will be
+// in the output while the fields will be automatically added to all log printouts.
+//
+// log.AddPackage(mylog.JSON, log.WarnLevel, log.Fields{"anyFieldName": "any value"})
+//
+//2. In the calling package, just invoke any of the publicly available functions of the logger. Here is an example
+// to write an Info log with additional fields:
+//
+//log.Infow("An example", mylog.Fields{"myStringOutput": "output", "myIntOutput": 2})
+//
+//3. To dynamically change the log level, you can use 1)SetLogLevel from inside your package or 2) SetPackageLogLevel
+// from anywhere or 3) SetAllLogLevel from anywhere.

+# voltha-protos
+
+Protobuf files used by [VOLTHA](https://wiki.opencord.org/display/CORD/VOLTHA).
+
+Currently this is used to generate both Golang and Python protobufs and gRPC
+stubs.
+
+The testing process is dependent on specific versions of the protobuf tools, so
+make sure to use the versions of `protoc` and `protoc-gen-go` specified below.
+
+Protobuf definition files are located in `protos/voltha_protos` directory. This
+directory hierarchy and import scheme is required to allow the python code
+generated by the gRPC compiler to [have the correct import
+paths](https://github.com/grpc/grpc/issues/9575#issuecomment-293934506).
+
+> NOTE: The `protos/google/api` directory has files copied from the [Google
+> APIs](https://github.com/googleapis/googleapis), and is only included for
+> initial compilation of the VOLTHA protobuf files - these API's should be
+> installed independently via either the python
+> [googleapis-common-protos](https://pypi.org/project/googleapis-common-protos/)
+> package or the golang [go-genproto](https://github.com/google/go-genproto)
+> repo.
+
+## Go Environment
+
+Get the voltha-protos repository:
+
+```sh
+mkdir -p ~/source
+cd ~/source
+git clone https://gerrit.opencord.org/voltha-protos
+cd voltha-protos
+```
+
+### Setting up the Go environment
+
+After installing Go on a Mac or Linux environment, the GOPATH environment
+variable needs be set. These instructions assume it's `~/go`.
+
+Create a symbolic link in the $GOPATH/src tree to the voltha-go repository:
+
+```sh
+mkdir -p $GOPATH/src/github.com/opencord
+ln -s ~/source/voltha-protos $GOPATH/src/github.com/opencord/voltha-protos
+```
+
+## Go Dependencies
+
+### Install Dependencies
+
+Checkout and go install correct version of protoc-gen-go:
+
+```sh
+GIT_TAG="v1.3.1"
+go get -d -u github.com/golang/protobuf/protoc-gen-go
+git -C "$(go env GOPATH)"/src/github.com/golang/protobuf checkout $GIT_TAG
+go install github.com/golang/protobuf/protoc-gen-go
+```
+
+## Building locally
+
+Install the protobuf compiler (protoc) 3.7.0 either manually or via the
+Makefile target (if on Linux amd64). Then build the python and golang stubs:
+
+```sh
+cd $GOPATH/src/github.com/opencord/voltha-protos
+make install-protoc
+make build
+```
+
+use dist/*.tar.gz for local python imports
+use go/ for local go imports
+
+## Using voltha-protos in your project
+
+### Python
+
+Installation from Pypi:
+
+`pip install voltha-protos`
+
+or from a local build:
+
+`pip install ~/source/voltha-protos/dist/*.tar.gz`
+
+To use it within your code (for example)
+
+`from voltha_protos import voltha_pb2`
+
+### Go
+
+```sh
+go get github.com/opencord/voltha-protos
+cd $GOPATH/github.com/opencord/voltha-protos
+make build
+````
+
+Protos are importable from `github.com/opencord/voltha-protos/go/<packagename>`
+
+To use the libraries, import protos with the root path github.com/opencord/voltha-protos/go/
+
+## Testing
+
+`make test` will run tests for all languages.

+// # gRPC Transcoding
+//
+// gRPC Transcoding is a feature for mapping between a gRPC method and one or
+// more HTTP REST endpoints. It allows developers to build a single API service
+// that supports both gRPC APIs and REST APIs. Many systems, including [Google
+// APIs](https://github.com/googleapis/googleapis),
+// [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+// Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+// and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+// and use it for large scale production services.
+//
+// `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+// how different portions of the gRPC request message are mapped to the URL
+// path, URL query parameters, and HTTP request body. It also controls how the
+// gRPC response message is mapped to the HTTP response body. `HttpRule` is
+// typically specified as an `google.api.http` annotation on the gRPC method.
+//
+// Each mapping specifies a URL path template and an HTTP method. The path
+// template may refer to one or more fields in the gRPC request message, as long
+// as each field is a non-repeated field with a primitive (non-message) type.
+// The path template controls how fields of the request message are mapped to
+// the URL path.
+//
+// Example:
+//
+// service Messaging {
+// rpc GetMessage(GetMessageRequest) returns (Message) {
+// option (google.api.http) = {
+// get: "/v1/{name=messages/*}"
+// };
+// }
+// }
+// message GetMessageRequest {
+// string name = 1; // Mapped to URL path.
+// }
+// message Message {
+// string text = 1; // The resource content.
+// }
+//
+// This enables an HTTP REST to gRPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(name: "messages/123456")`
+//
+// Any fields in the request message which are not bound by the path template
+// automatically become HTTP query parameters if there is no HTTP request body.
+// For example:
+//
+// service Messaging {
+// rpc GetMessage(GetMessageRequest) returns (Message) {
+// option (google.api.http) = {
+// get:"/v1/messages/{message_id}"
+// };
+// }
+// }
+// message GetMessageRequest {
+// message SubMessage {
+// string subfield = 1;
+// }
+// string message_id = 1; // Mapped to URL path.
+// int64 revision = 2; // Mapped to URL query parameter `revision`.
+// SubMessage sub = 3; // Mapped to URL query parameter `sub.subfield`.
+// }
+//
+// This enables a HTTP JSON to RPC mapping as below:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+// `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+// "foo"))`
+//
+// Note that fields which are mapped to URL query parameters must have a
+// primitive type or a repeated primitive type or a non-repeated message type.
+// In the case of a repeated type, the parameter can be repeated in the URL
+// as `...?param=A¶m=B`. In the case of a message type, each field of the
+// message is mapped to a separate parameter, such as
+// `...?foo.a=A&foo.b=B&foo.c=C`.
+//
+// For HTTP methods that allow a request body, the `body` field
+// specifies the mapping. Consider a REST update method on the
+// message resource collection:
+//
+// service Messaging {
+// rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+// option (google.api.http) = {
+// patch: "/v1/messages/{message_id}"
+// body: "message"
+// };
+// }
+// }
+// message UpdateMessageRequest {
+// string message_id = 1; // mapped to the URL
+// Message message = 2; // mapped to the body
+// }
+//
+// The following HTTP JSON to RPC mapping is enabled, where the
+// representation of the JSON in the request body is determined by
+// protos JSON encoding:
+//
+// HTTP | gRPC
+// -----|-----
+// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+// "123456" message { text: "Hi!" })`
+//
+// The special name `*` can be used in the body mapping to define that
+// every field not bound by the path template should be mapped to the
+// request body. This enables the following alternative definition of
+// the update method:
+//
+// service Messaging {
+// rpc UpdateMessage(Message) returns (Message) {
+// option (google.api.http) = {
+// patch: "/v1/messages/{message_id}"
+// body: "*"
+// };
+// }
+// }
+// message Message {
+// string message_id = 1;
+// string text = 2;
+// }
+//
+//
+// The following HTTP JSON to RPC mapping is enabled:
+//
+// HTTP | gRPC
+// -----|-----
+// `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+// "123456" text: "Hi!")`
+//
+// Note that when using `*` in the body mapping, it is not possible to
+// have HTTP parameters, as all fields not bound by the path end in
+// the body. This makes this option more rarely used in practice when
+// defining REST APIs. The common usage of `*` is in custom methods
+// which don't use the URL at all for transferring data.
+//
+// It is possible to define multiple HTTP methods for one RPC by using
+// the `additional_bindings` option. Example:
+//
+// service Messaging {
+// rpc GetMessage(GetMessageRequest) returns (Message) {
+// option (google.api.http) = {
+// get: "/v1/messages/{message_id}"
+// additional_bindings {
+// get: "/v1/users/{user_id}/messages/{message_id}"
+// }
+// };
+// }
+// }
+// message GetMessageRequest {
+// string message_id = 1;
+// string user_id = 2;
+// }
+//
+// This enables the following two alternative HTTP JSON to RPC mappings:
+//
+// HTTP | gRPC
+// -----|-----
+// `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+// `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+// "123456")`
+//
+// ## Rules for HTTP mapping
+//
+// 1. Leaf request fields (recursive expansion nested messages in the request
+// message) are classified into three categories:
+// - Fields referred by the path template. They are passed via the URL path.
+// - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They
+// are passed via the HTTP
+// request body.
+// - All other fields are passed via the URL query parameters, and the
+// parameter name is the field path in the request message. A repeated
+// field can be represented as multiple query parameters under the same
+// name.
+// 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL
+// query parameter, all fields
+// are passed via URL path and HTTP request body.
+// 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP
+// request body, all
+// fields are passed via URL path and URL query parameters.
+//
+// ### Path template syntax
+//
+// Template = "/" Segments [ Verb ] ;
+// Segments = Segment { "/" Segment } ;
+// Segment = "*" | "**" | LITERAL | Variable ;
+// Variable = "{" FieldPath [ "=" Segments ] "}" ;
+// FieldPath = IDENT { "." IDENT } ;
+// Verb = ":" LITERAL ;
+//
+// The syntax `*` matches a single URL path segment. The syntax `**` matches
+// zero or more URL path segments, which must be the last part of the URL path
+// except the `Verb`.
+//
+// The syntax `Variable` matches part of the URL path as specified by its
+// template. A variable template must not contain other variables. If a variable
+// matches a single path segment, its template may be omitted, e.g. `{var}`
+// is equivalent to `{var=*}`.
+//
+// The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+// contains any reserved character, such characters should be percent-encoded
+// before the matching.
+//
+// If a variable contains exactly one path segment, such as `"{var}"` or
+// `"{var=*}"`, when such a variable is expanded into a URL path on the client
+// side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+// server side does the reverse decoding. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{var}`.
+//
+// If a variable contains multiple path segments, such as `"{var=foo/*}"`
+// or `"{var=**}"`, when such a variable is expanded into a URL path on the
+// client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+// The server side does the reverse decoding, except "%2F" and "%2f" are left
+// unchanged. Such variables show up in the
+// [Discovery
+// Document](https://developers.google.com/discovery/v1/reference/apis) as
+// `{+var}`.
+//
+// ## Using gRPC API Service Configuration
+//
+// gRPC API Service Configuration (service config) is a configuration language
+// for configuring a gRPC service to become a user-facing product. The
+// service config is simply the YAML representation of the `google.api.Service`
+// proto message.
+//
+// As an alternative to annotating your proto file, you can configure gRPC
+// transcoding in your service config YAML files. You do this by specifying a
+// `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+// effect as the proto annotation. This can be particularly useful if you
+// have a proto that is reused in multiple services. Note that any transcoding
+// specified in the service config will override any matching transcoding
+// configuration in the proto.
+//
+// Example:
+//
+// http:
+// rules:
+// # Selects a gRPC method and applies HttpRule to it.
+// - selector: example.v1.Messaging.GetMessage
+// get: /v1/messages/{message_id}/{sub.subfield}
+//
+// ## Special notes
+//
+// When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+// proto to JSON conversion must follow the [proto3
+// specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+//
+// While the single segment variable follows the semantics of
+// [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+// Expansion, the multi segment variable **does not** follow RFC 6570 Section
+// 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+// does not expand special characters like `?` and `#`, which would lead
+// to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+// for multi segment variables.
+//
+// The path variables **must not** refer to any repeated or mapped field,
+// because client libraries are not capable of handling such variable expansion.
+//
+// The path variables **must not** capture the leading "/" character. The reason
+// is that the most common use case "{var}" does not capture the leading "/"
+// character. For consistency, all path variables must share the same behavior.
+//
+// Repeated message fields must not be mapped to URL query parameters, because
+// no client library can support such complicated mapping.
+//
+// If an API needs to use a JSON array for request or response body, it can map
+// the request or response body to a repeated field. However, some gRPC
+// Transcoding implementations may not support this feature.

+# lz4
+LZ4 compression and decompression in pure Go.
+
+## Usage
+
+```go
+import "github.com/pierrec/lz4"
+```
+
+## Description
+Package lz4 implements reading and writing lz4 compressed data (a frame),
+as specified in http://fastcompression.blogspot.fr/2013/04/lz4-streaming-format-final.html.
+
+This package is **compatible with the LZ4 frame format** although the block level compression
+and decompression functions are exposed and are fully compatible with the lz4 block format
+definition, they are low level and should not be used directly.
+
+For a complete description of an lz4 compressed block, see:
+http://fastcompression.blogspot.fr/2011/05/lz4-explained.html
+
+See https://github.com/Cyan4973/lz4 for the reference C implementation.

+// SequenceMatcher compares sequence of strings. The basic
+// algorithm predates, and is a little fancier than, an algorithm
+// published in the late 1980's by Ratcliff and Obershelp under the
+// hyperbolic name "gestalt pattern matching". The basic idea is to find
+// the longest contiguous matching subsequence that contains no "junk"
+// elements (R-O doesn't address junk). The same idea is then applied
+// recursively to the pieces of the sequences to the left and to the right
+// of the matching subsequence. This does not yield minimal edit
+// sequences, but does tend to yield matches that "look right" to people.
+//
+// SequenceMatcher tries to compute a "human-friendly diff" between two
+// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
+// longest *contiguous* & junk-free matching subsequence. That's what
+// catches peoples' eyes. The Windows(tm) windiff has another interesting
+// notion, pairing up elements that appear uniquely in each sequence.
+// That, and the method here, appear to yield more intuitive difference
+// reports than does diff. This method appears to be the least vulnerable
+// to synching up on blocks of "junk lines", though (like blank lines in
+// ordinary text files, or maybe "<P>" lines in HTML files). That may be
+// because this is the only method of the 3 that has a *concept* of
+// "junk" <wink>.
+//
+// Timing: Basic R-O is cubic time worst case and quadratic time expected
+// case. SequenceMatcher is quadratic time for the worst case and has
+// expected-case behavior dependent in a complicated way on how many
+// elements the sequences have in common; best case time is linear.

+Register() is not threadsafe. For threadsafe metric registration use
+GetOrRegister:
+
+```go
+t := metrics.GetOrRegisterTimer("account.create.latency", nil)
+t.Time(func() {})
+t.Update(47)
+```
+
+**NOTE:** Be sure to unregister short-lived meters and timers otherwise they will
+leak memory:
+
+```go
+// Will call Stop() on the Meter to allow for garbage collection
+metrics.Unregister("quux")
+// Or similarly for a Timer that embeds a Meter
+metrics.Unregister("bang")
+```
+
+Periodically log every metric in human-readable form to standard error:
+
+```go
+go metrics.Log(metrics.DefaultRegistry, 5 * time.Second, log.New(os.Stderr, "metrics: ", log.Lmicroseconds))
+```
+
+Periodically log every metric in slightly-more-parseable form to syslog:
+
+```go
+w, _ := syslog.Dial("unixgram", "/dev/log", syslog.LOG_INFO, "metrics")
+go metrics.Syslog(metrics.DefaultRegistry, 60e9, w)
+```
+
+Periodically emit every metric to Graphite using the [Graphite client](https://github.com/cyberdelia/go-metrics-graphite):
+
+```go
+
+import "github.com/cyberdelia/go-metrics-graphite"
+
+addr, _ := net.ResolveTCPAddr("tcp", "127.0.0.1:2003")
+go graphite.Graphite(metrics.DefaultRegistry, 10e9, "metrics", addr)
+```
+
+Periodically emit every metric into InfluxDB:
+
+**NOTE:** this has been pulled out of the library due to constant fluctuations
+in the InfluxDB API. In fact, all client libraries are on their way out. see
+issues [#121](https://github.com/rcrowley/go-metrics/issues/121) and
+[#124](https://github.com/rcrowley/go-metrics/issues/124) for progress and details.
+
+```go
+import "github.com/vrischmann/go-metrics-influxdb"
+
+go influxdb.InfluxDB(metrics.DefaultRegistry,
+ 10e9,
+ "127.0.0.1:8086",
+ "database-name",
+ "username",
+ "password"
+)
+```
+
+Periodically upload every metric to Librato using the [Librato client](https://github.com/mihasya/go-metrics-librato):
+
+**Note**: the client included with this repository under the `librato` package
+has been deprecated and moved to the repository linked above.
+
+```go
+import "github.com/mihasya/go-metrics-librato"
+
+go librato.Librato(metrics.DefaultRegistry,
+ 10e9, // interval
+ "example@example.com", // account owner email address
+ "token", // Librato API token
+ "hostname", // source
+ []float64{0.95}, // percentiles to send
+ time.Millisecond, // time unit
+)
+```
+
+Periodically emit every metric to StatHat:
+
+```go
+import "github.com/rcrowley/go-metrics/stathat"
+
+go stathat.Stathat(metrics.DefaultRegistry, 10e9, "example@example.com")
+```
+
+Maintain all metrics along with expvars at `/debug/metrics`:
+
+This uses the same mechanism as [the official expvar](http://golang.org/pkg/expvar/)
+but exposed under `/debug/metrics`, which shows a json representation of all your usual expvars
+as well as all your go-metrics.
+
+
+```go
+import "github.com/rcrowley/go-metrics/exp"
+
+exp.Exp(metrics.DefaultRegistry)
+```
+
+Installation
+------------
+
+```sh
+go get github.com/rcrowley/go-metrics
+```
+
+StatHat support additionally requires their Go client:
+
+```sh
+go get github.com/stathat/go
+```

+// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
+//
+// Example Usage
+//
+// The following is a complete example using assert in a standard test function:
+// import (
+// "testing"
+// "github.com/stretchr/testify/assert"
+// )
+//
+// func TestSomething(t *testing.T) {
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// assert.Equal(t, a, b, "The two words should be the same.")
+//
+// }
+//
+// if you assert many times, use the format below:
+//
+// import (
+// "testing"
+// "github.com/stretchr/testify/assert"
+// )
+//
+// func TestSomething(t *testing.T) {
+// assert := assert.New(t)
+//
+// var a string = "Hello"
+// var b string = "Hello"
+//
+// assert.Equal(a, b, "The two words should be the same.")
+// }
+//
+// Assertions
+//
+// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
+// All assertion functions take, as the first argument, the `*testing.T` object provided by the
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.
