+ 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.
+- All the configuration values have been unified in the `Config` struct.
+- Much improved test suite.

+
+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 1.12 through 1.13, and Kafka 2.1 through 2.4, 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 immediately. 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.

+ // AsyncClose initiates a shutdown of the PartitionConsumer. This method will return immediately, after which you
+ // should continue to service the 'Messages' and 'Errors' channels until they are empty. It is required to call this
+ // function, or Close before a consumer object passes out of scope, as it will otherwise leak memory. You must call
+ // 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
+ // the Messages channel, harvest any errors & return them to the caller. Note that if you are continuing to service
+ // the Messages channel when this function is called, you will be competing with Close for messages; consider

+/*
+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 Consumer or Consumer-Group API.
+
+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.

+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.

+The configuration options are controlled by an exported package global,

+
+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)
+for guaranteed API stability.

+ are equal, and extensions sets are equal.

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

+/*
+Package proto converts data structures to and from the wire format of
+protocol buffers. It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+ - Names are turned from camel_case to CamelCase for export.
+ - There are no methods on v to set fields; just treat
+ them as structure fields.
+ - There are getters that return a field's value if set,
+ and return the field's default value if unset.
+ The getters work even if the receiver is a nil message.
+ - The zero value for a struct is its correct initialization state.
+ All desired fields must be set before marshaling.
+ - A Reset() method will restore a protobuf struct to its zero state.
+ - Non-repeated fields are pointers to the values; nil means unset.
+ That is, optional or required field int32 f becomes F *int32.
+ - Repeated fields are slices.
+ - Helper functions are available to aid the setting of fields.
+ msg.Foo = proto.String("hello") // set field
+ - Constants are defined to hold the default values of all fields that
+ have them. They have the form Default_StructName_FieldName.
+ Because the getter methods handle defaulted values,
+ direct use of these constants should be rare.
+ - Enums are given type names and maps from names to values.
+ Enum values are prefixed by the enclosing message's name, or by the
+ enum's type name if it is a top-level enum. Enum types have a String
+ method, and a Enum method to assist in message construction.
+ - Nested messages, groups and enums have type names prefixed with the name of
+ the surrounding message type.
+ - Extensions are given descriptor names that start with E_,
+ followed by an underscore-delimited list of the nested messages
+ that contain it (if any) followed by the CamelCased name of the
+ extension field itself. HasExtension, ClearExtension, GetExtension
+ and SetExtension are functions for manipulating extensions.
+ - Oneof field sets are given a single field in their message,
+ with distinguished wrapper types for each possible field value.
+ - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+ - Non-repeated fields of non-message type are values instead of pointers.
+ - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+ package example;
+
+ enum FOO { X = 17; }
+
+ message Test {
+ required string label = 1;
+ optional int32 type = 2 [default=77];
+ repeated int64 reps = 3;
+ optional group OptionalGroup = 4 {
+ required string RequiredField = 5;
+ }
+ oneof union {
+ int32 number = 6;
+ string name = 7;
+ }
+ }
+
+The resulting file, test.pb.go, is:
+
+ package example
+
+ import proto "github.com/golang/protobuf/proto"
+ import math "math"
+
+ type FOO int32
+ const (
+ FOO_X FOO = 17
+ )
+ var FOO_name = map[int32]string{
+ 17: "X",
+ }
+ var FOO_value = map[string]int32{
+ "X": 17,
+ }
+

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

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

+// 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;
+// message Person {

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

+//
+// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+// Timestamp timestamp;
+// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+// long millis = System.currentTimeMillis();
+//
+// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+// .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from current time in Python.
+//
+// timestamp = Timestamp()
+// timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString]
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
+// with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
+// can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime--
+// ) to obtain a formatter capable of generating timestamps in this format.

+ // and repeat the exercise until the two no longer overlap.
+ //
+ // This allows us to do very well in the special case of one single byte
+ // repeated many times, without taking a big hit for more general cases.

+// 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).
+
+###### Install
+`go get github.com/google/uuid`

+
+2. License Grants and Conditions
+
+2.1. Grants
+
+ 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

+
+2.2. Effective Date
+
+ 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.
+

+relevant directory) where a recipient would be likely to look for such a
+notice.
+

+Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
+2898 / PKCS #5 v2.0.
+
+A key derivation function is useful when encrypting data based on a password
+or any other not-fully-random data. It uses a pseudorandom function to derive
+a secure encryption key based on the password.
+
+While v2.0 of the standard defines only one pseudorandom function to use,
+HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
+Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
+choose, you can pass the `New` functions from the different SHA packages to
+pbkdf2.Key.

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

+# Huff0 entropy compression
+
+This package provides Huff0 encoding and decoding as used in zstd.
+
+[Huff0](https://github.com/Cyan4973/FiniteStateEntropy#new-generation-entropy-coders),
+a Huffman codec designed for modern CPU, featuring OoO (Out of Order) operations on multiple ALU
+(Arithmetic Logic Unit), achieving extremely fast compression and decompression speeds.
+
+This can be used for compressing input with a lot of similar input values to the smallest number of bytes.
+This does not perform any multi-byte [dictionary coding](https://en.wikipedia.org/wiki/Dictionary_coder) as LZ coders,
+but it can be used as a secondary step to compressors (like Snappy) that does not do entropy encoding.
+
+* [Godoc documentation](https://godoc.org/github.com/klauspost/compress/huff0)
+
+THIS PACKAGE IS NOT CONSIDERED STABLE AND API OR ENCODING MAY CHANGE IN THE FUTURE.
+
+## News
+
+ * Mar 2018: First implementation released. Consider this beta software for now.
+
+# Usage
+
+This package provides a low level interface that allows to compress single independent blocks.
+
+Each block is separate, and there is no built in integrity checks.
+This means that the caller should keep track of block sizes and also do checksums if needed.
+
+Compressing a block is done via the [`Compress1X`](https://godoc.org/github.com/klauspost/compress/huff0#Compress1X) and
+[`Compress4X`](https://godoc.org/github.com/klauspost/compress/huff0#Compress4X) functions.
+You must provide input and will receive the output and maybe an error.
+
+These error values can be returned:
+
+| Error | Description |
+|---------------------|-----------------------------------------------------------------------------|
+| `<nil>` | Everything ok, output is returned |
+| `ErrIncompressible` | Returned when input is judged to be too hard to compress |
+| `ErrUseRLE` | Returned from the compressor when the input is a single byte value repeated |
+| `ErrTooBig` | Returned if the input block exceeds the maximum allowed size (128 Kib) |
+| `(error)` | An internal error occurred. |
+
+
+As can be seen above some of there are errors that will be returned even under normal operation so it is important to handle these.
+
+To reduce allocations you can provide a [`Scratch`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch) object
+that can be re-used for successive calls. Both compression and decompression accepts a `Scratch` object, and the same
+object can be used for both.
+
+Be aware, that when re-using a `Scratch` object that the *output* buffer is also re-used, so if you are still using this
+you must set the `Out` field in the scratch to nil. The same buffer is used for compression and decompression output.
+
+The `Scratch` object will retain state that allows to re-use previous tables for encoding and decoding.
+
+## Tables and re-use
+
+Huff0 allows for reusing tables from the previous block to save space if that is expected to give better/faster results.
+
+The Scratch object allows you to set a [`ReusePolicy`](https://godoc.org/github.com/klauspost/compress/huff0#ReusePolicy)
+that controls this behaviour. See the documentation for details. This can be altered between each block.
+
+Do however note that this information is *not* stored in the output block and it is up to the users of the package to
+record whether [`ReadTable`](https://godoc.org/github.com/klauspost/compress/huff0#ReadTable) should be called,
+based on the boolean reported back from the CompressXX call.
+
+If you want to store the table separate from the data, you can access them as `OutData` and `OutTable` on the
+[`Scratch`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch) object.
+
+## Decompressing
+
+The first part of decoding is to initialize the decoding table through [`ReadTable`](https://godoc.org/github.com/klauspost/compress/huff0#ReadTable).
+This will initialize the decoding tables.
+You can supply the complete block to `ReadTable` and it will return the data part of the block
+which can be given to the decompressor.
+
+Decompressing is done by calling the [`Decompress1X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress1X)
+or [`Decompress4X`](https://godoc.org/github.com/klauspost/compress/huff0#Scratch.Decompress4X) function.
+
+You must provide the output from the compression stage, at exactly the size you got back. If you receive an error back
+your input was likely corrupted.
+
+It is important to note that a successful decoding does *not* mean your output matches your original input.
+There are no integrity checks, so relying on errors from the decompressor does not assure your data is valid.
+
+# Contributing
+
+Contributions are always welcome. Be aware that adding public functions will require good justification and breaking
+changes will likely not be accepted. If in doubt open an issue before writing the PR.

+// 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 (
+ "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).

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

+### Converters
+
+As part of the development process a *Snappy* -> *Zstandard* converter was also built.
+
+This can convert a *framed* [Snappy Stream](https://godoc.org/github.com/golang/snappy#Writer) to a zstd stream.
+Note that a single block is not framed.
+
+Conversion is done by converting the stream directly from Snappy without intermediate full decoding.
+Therefore the compression ratio is much less than what can be done by a full decompression
+and compression, and a faulty Snappy stream may lead to a faulty Zstandard stream without
+any errors being generated.
+No CRC value is being generated and not all CRC values of the Snappy stream are checked.
+However, it provides really fast re-compression of Snappy streams.
+
+
+```
+BenchmarkSnappy_ConvertSilesia-8 1 1156001600 ns/op 183.35 MB/s
+Snappy len 103008711 -> zstd len 82687318
+
+BenchmarkSnappy_Enwik9-8 1 6472998400 ns/op 154.49 MB/s
+Snappy len 508028601 -> zstd len 390921079
+```
+
+
+```Go
+ s := zstd.SnappyConverter{}
+ n, err = s.Convert(input, output)
+ if err != nil {
+ fmt.Println("Re-compressed stream to", n, "bytes")
+ }
+```
+
+The converter `s` can be reused to avoid allocations, even after errors.
+
+
+## Decompressor
+
+Staus: STABLE - there may still be subtle bugs, but a wide variety of content has been tested.
+
+This library is being continuously [fuzz-tested](https://github.com/klauspost/compress-fuzz),
+kindly supplied by [fuzzit.dev](https://fuzzit.dev/).
+The main purpose of the fuzz testing is to ensure that it is not possible to crash the decoder,
+or run it past its limits with ANY input provided.
+
+### Usage
+
+The package has been designed for two main usages, big streams of data and smaller in-memory buffers.
+There are two main usages of the package for these. Both of them are accessed by creating a `Decoder`.
+
+For streaming use a simple setup could look like this:
+
+```Go
+import "github.com/klauspost/compress/zstd"
+
+func Decompress(in io.Reader, out io.Writer) error {
+ d, err := zstd.NewReader(input)
+ if err != nil {
+ return err
+ }
+ defer d.Close()
+
+ // Copy content...
+ _, err := io.Copy(out, d)
+ return err
+}
+```
+
+It is important to use the "Close" function when you no longer need the Reader to stop running goroutines.
+See "Allocation-less operation" below.
+
+For decoding buffers, it could look something like this:
+
+```Go
+import "github.com/klauspost/compress/zstd"
+
+// Create a reader that caches decompressors.
+// For this operation type we supply a nil Reader.
+var decoder, _ = zstd.NewReader(nil)
+
+// Decompress a buffer. We don't supply a destination buffer,
+// so it will be allocated by the decoder.
+func Decompress(src []byte) ([]byte, error) {
+ return decoder.DecodeAll(src, nil)
+}
+```
+
+Both of these cases should provide the functionality needed.
+The decoder can be used for *concurrent* decompression of multiple buffers.
+It will only allow a certain number of concurrent operations to run.
+To tweak that yourself use the `WithDecoderConcurrency(n)` option when creating the decoder.
+
+### Allocation-less operation
+
+The decoder has been designed to operate without allocations after a warmup.
+
+This means that you should *store* the decoder for best performance.
+To re-use a stream decoder, use the `Reset(r io.Reader) error` to switch to another stream.
+A decoder can safely be re-used even if the previous stream failed.
+
+To release the resources, you must call the `Close()` function on a decoder.
+After this it can *no longer be reused*, but all running goroutines will be stopped.
+So you *must* use this if you will no longer need the Reader.
+
+For decompressing smaller buffers a single decoder can be used.
+When decoding buffers, you can supply a destination slice with length 0 and your expected capacity.
+In this case no unneeded allocations should be made.
+
+### Concurrency
+
+The buffer decoder does everything on the same goroutine and does nothing concurrently.
+It can however decode several buffers concurrently. Use `WithDecoderConcurrency(n)` to limit that.
+
+The stream decoder operates on
+
+* One goroutine reads input and splits the input to several block decoders.
+* A number of decoders will decode blocks.
+* A goroutine coordinates these blocks and sends history from one to the next.
+
+So effectively this also means the decoder will "read ahead" and prepare data to always be available for output.
+
+Since "blocks" are quite dependent on the output of the previous block stream decoding will only have limited concurrency.
+
+In practice this means that concurrency is often limited to utilizing about 2 cores effectively.
+
+
+### Benchmarks
+
+These are some examples of performance compared to [datadog cgo library](https://github.com/DataDog/zstd).
+
+The first two are streaming decodes and the last are smaller inputs.

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

+# lz4 : LZ4 compression in pure Go
+
+[](https://godoc.org/github.com/pierrec/lz4)
+[](https://travis-ci.org/pierrec/lz4)
+[](https://goreportcard.com/report/github.com/pierrec/lz4)
+[](https://github.com/pierrec/lz4/tags)
+
+## Overview
+
+This package provides a streaming interface to [LZ4 data streams](http://fastcompression.blogspot.fr/2013/04/lz4-streaming-format-final.html) as well as low level compress and uncompress functions for LZ4 data blocks.
+The implementation is based on the reference C [one](https://github.com/lz4/lz4).
+
+## Install
+
+Assuming you have the go toolchain installed:
+
+```
+go get github.com/pierrec/lz4
+```
+
+There is a command line interface tool to compress and decompress LZ4 files.
+
+```
+go install github.com/pierrec/lz4/cmd/lz4c
+```
+
+Usage
+
+```
+Usage of lz4c:
+ -version
+ print the program version
+
+Subcommands:
+Compress the given files or from stdin to stdout.
+compress [arguments] [<file name> ...]
+ -bc
+ enable block checksum
+ -l int
+ compression level (0=fastest)
+ -sc
+ disable stream checksum
+ -size string
+ block max size [64K,256K,1M,4M] (default "4M")
+
+Uncompress the given files or from stdin to stdout.
+uncompress [arguments] [<file name> ...]
+
+```
+
+
+## Example
+
+```
+// Compress and uncompress an input string.
+s := "hello world"
+r := strings.NewReader(s)
+
+// The pipe will uncompress the data from the writer.
+pr, pw := io.Pipe()
+zw := lz4.NewWriter(pw)
+zr := lz4.NewReader(pr)
+
+go func() {
+ // Compress the input string.
+ _, _ = io.Copy(zw, r)
+ _ = zw.Close() // Make sure the writer is closed
+ _ = pw.Close() // Terminate the pipe
+}()
+
+_, _ = io.Copy(os.Stdout, zr)
+
+// Output:
+// hello world
+```

+go-metrics
+==========
+
+
+
+Go port of Coda Hale's Metrics library: <https://github.com/dropwizard/metrics>.
+
+Documentation: <http://godoc.org/github.com/rcrowley/go-metrics>.
+
+Usage
+-----
+
+Create and update metrics:
+
+```go
+c := metrics.NewCounter()
+metrics.Register("foo", c)
+c.Inc(47)
+
+g := metrics.NewGauge()
+metrics.Register("bar", g)
+g.Update(47)
+
+r := NewRegistry()
+g := metrics.NewRegisteredFunctionalGauge("cache-evictions", r, func() int64 { return cache.getEvictionsCount() })
+
+s := metrics.NewExpDecaySample(1028, 0.015) // or metrics.NewUniformSample(1028)
+h := metrics.NewHistogram(s)
+metrics.Register("baz", h)
+h.Update(47)
+
+m := metrics.NewMeter()
+metrics.Register("quux", m)
+m.Mark(47)
+
+t := metrics.NewTimer()
+metrics.Register("bang", t)
+t.Time(func() {})
+t.Update(47)
+```
+
+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
+```
