-# Changelog
-
-#### Version 1.11.0 (2016-12-20)
-
-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.

-======
-
-[](https://godoc.org/github.com/Shopify/sarama)
-[](https://travis-ci.org/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.
-
-### 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 1.7 and 1.6, and Kafka 0.10.0 and 0.9.0, 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/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!

-# sarama/mocks
-
-The `mocks` subpackage includes mock implementations that implement the interfaces of the major sarama types.
-You can use them to test your sarama applications using dependency injection.
-
-The following mock objects are available:
-
-- [Consumer](https://godoc.org/github.com/Shopify/sarama/mocks#Consumer), which will create [PartitionConsumer](https://godoc.org/github.com/Shopify/sarama/mocks#PartitionConsumer) mocks.
-- [AsyncProducer](https://godoc.org/github.com/Shopify/sarama/mocks#AsyncProducer)
-- [SyncProducer](https://godoc.org/github.com/Shopify/sarama/mocks#SyncProducer)
-
-The mocks allow you to set expectations on them. When you close the mocks, the expectations will be verified,
-and the results will be reported to the `*testing.T` object you provided when creating the mock.

-/*
-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:
-

-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)
- }),
- 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 <*>}
- %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)}
- %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)}
- %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)}
-
-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.

-- success threshold (for closing the breaker)
-- timeout (how long to keep the breaker open)

-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

- // this, with the eight-byte and patterns marked as

- //
- // abxxxxxxxxxxxx
- // [------] d-offset
- // [------] d
- //
- // a single eight-byte copy from to will repeat the pattern
- // once, after which we can move two bytes without moving :
- //
- // ababxxxxxxxxxx
- // [------] d-offset
- // [------] d
- //
- // and repeat the exercise until the two no longer overlap.
- //
- // This allows us to do very well in the special case of one single byte
- // repeated many times, without taking a big hit for more general cases.
- //
- // The worst case of extra writing past the end of the match occurs when
- // offset == 1 and length == 1; the last copy will read from byte positions
- // [0..7] and write to [4..11], whereas it was only supposed to write to

-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.

-# crc32
-CRC32 hash with x64 optimizations
-
-This package is a drop-in replacement for the standard library `hash/crc32` package, that features SSE 4.2 optimizations on x64 platforms, for a 10x speedup.
-
-[](https://travis-ci.org/klauspost/crc32)
-
-# usage
-
-Install using `go get github.com/klauspost/crc32`. This library is based on Go 1.5 code and requires Go 1.3 or newer.
-
-Replace `import "hash/crc32"` with `import "github.com/klauspost/crc32"` and you are good to go.
-
-# changes
-* Oct 20, 2016: Changes have been merged to upstream Go. Package updated to match.
-* Dec 4, 2015: Uses the "slice-by-8" trick more extensively, which gives a 1.5 to 2.5x speedup if assembler is unavailable.
-
-
-# performance
-
-For *Go 1.7* performance is equivalent to the standard library. So if you use this package for Go 1.7 you can switch back.
-
-
-For IEEE tables (the most common), there is approximately a factor 10 speedup with "CLMUL" (Carryless multiplication) instruction:
-```
-benchmark old ns/op new ns/op delta
-BenchmarkCrc32KB 99955 10258 -89.74%
-
-benchmark old MB/s new MB/s speedup
-BenchmarkCrc32KB 327.83 3194.20 9.74x
-```
-
-For other tables and "CLMUL" capable machines the performance is the same as the standard library.
-
-Here are some detailed benchmarks, comparing to go 1.5 standard library with and without assembler enabled.
-
-```
-Std: Standard Go 1.5 library
-Crc: Indicates IEEE type CRC.
-40B: Size of each slice encoded.
-NoAsm: Assembler was disabled (ie. not an AMD64 or SSE 4.2+ capable machine).
-Castagnoli: Castagnoli CRC type.

-
-The IEEE assembler optimizations has been submitted and will be part of the Go 1.6 standard library.
-
-However, the improved use of slice-by-8 has not, but will probably be submitted for Go 1.7.

- // This method is inspired from the algorithm in Intel's white paper:
- // "Fast CRC Computation for iSCSI Polynomial Using CRC32 Instruction"
- // The same strategy of splitting the buffer in three is used but the
- // combining calculation is different; the complete derivation is explained
- // below.
- //
- // -- The basic idea --
- //
- // The CRC32 instruction (available in SSE4.2) can process 8 bytes at a
- // time. In recent Intel architectures the instruction takes 3 cycles;
- // however the processor can pipeline up to three instructions if they
- // don't depend on each other.
- //
- // Roughly this means that we can process three buffers in about the same
- // time we can process one buffer.
- //
- // The idea is then to split the buffer in three, CRC the three pieces
- // separately and then combine the results.
- //
- // Combining the results requires precomputed tables, so we must choose a
- // fixed buffer length to optimize. The longer the length, the faster; but
- // only buffers longer than this length will use the optimization. We choose
- // two cutoffs and compute tables for both:
- // - one around 512: 168*3=504
- // - one around 4KB: 1344*3=4032
- //
- // -- The nitty gritty --
- //
- // Let CRC(I, X) be the non-inverted CRC32-C of the sequence X (with
- // initial non-inverted CRC I). This function has the following properties:
- // (a) CRC(I, AB) = CRC(CRC(I, A), B)
- // (b) CRC(I, A xor B) = CRC(I, A) xor CRC(0, B)
- //
- // Say we want to compute CRC(I, ABC) where A, B, C are three sequences of
- // K bytes each, where K is a fixed constant. Let O be the sequence of K zero
- // bytes.
- //
- // CRC(I, ABC) = CRC(I, ABO xor C)
- // = CRC(I, ABO) xor CRC(0, C)
- // = CRC(CRC(I, AB), O) xor CRC(0, C)
- // = CRC(CRC(I, AO xor B), O) xor CRC(0, C)
- // = CRC(CRC(I, AO) xor CRC(0, B), O) xor CRC(0, C)
- // = CRC(CRC(CRC(I, A), O) xor CRC(0, B), O) xor CRC(0, C)
- //
- // The castagnoliSSE42Triple function can compute CRC(I, A), CRC(0, B),
- // and CRC(0, C) efficiently. We just need to find a way to quickly compute
- // CRC(uvwx, O) given a 4-byte initial value uvwx. We can precompute these
- // values; since we can't have a 32-bit table, we break it up into four
- // 8-bit tables:
- //
- // CRC(uvwx, O) = CRC(u000, O) xor
- // CRC(0v00, O) xor
- // CRC(00w0, O) xor
- // CRC(000x, O)
- //
- // We can compute tables corresponding to the four terms for all 8-bit
- // values.

-# 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,
-using an io.Reader (decompression) and io.Writer (compression).
-It is designed to minimize memory usage while maximizing throughput by being able to
-[de]compress data concurrently.
-
-The Reader and the Writer support concurrent processing provided the supplied buffers are
-large enough (in multiples of BlockMaxSize) and there is no block dependency.
-Reader.WriteTo and Writer.ReadFrom do leverage the concurrency transparently.
-The runtime.GOMAXPROCS() value is used to apply concurrency or not.
-
-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.

-go-metrics
-==========
-
-
-
-Go port of Coda Hale's Metrics library: .
-
-Documentation: .
-
-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:
-
-```
-t := metrics.GetOrRegisterTimer("account.create.latency", nil)
-t.Time(func() {})
-t.Update(47)
-```
-
-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, &influxdb.Config{
- Host: "127.0.0.1:8086",
- Database: "metrics",
- Username: "test",
- Password: "test",
-})
-```
-
-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
-```
-
-Publishing Metrics

-# The unix package provides access to the raw system call
-# interface of the underlying operating system. Porting Go to
-# a new architecture/operating system combination requires
-# some manual effort, though there are tools that automate
-# much of the process. The auto-generated files have names
-# beginning with z.
-#
-# This script runs or (given -n) prints suggested commands to generate z files
-# for the current system. Running those commands is not automatic.
-# This script is documentation more than anything else.
-#
-# * asm_${GOOS}_${GOARCH}.s
-#
-# This hand-written assembly file implements system call dispatch.
-# There are three entry points:
-#
-# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
-# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
-# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
-#
-# The first and second are the standard ones; they differ only in
-# how many arguments can be passed to the kernel.
-# The third is for low-level use by the ForkExec wrapper;
-# unlike the first two, it does not call into the scheduler to
-# let it know that a system call is running.
-#
-# * syscall_${GOOS}.go
-#
-# This hand-written Go file implements system calls that need
-# special handling and lists "//sys" comments giving prototypes
-# for ones that can be auto-generated. Mksyscall reads those
-# comments to generate the stubs.
-#
-# * syscall_${GOOS}_${GOARCH}.go
-#
-# Same as syscall_${GOOS}.go except that it contains code specific
-# to ${GOOS} on one particular architecture.
-#
-# * types_${GOOS}.c
-#
-# This hand-written C file includes standard C headers and then
-# creates typedef or enum names beginning with a dollar sign
-# (use of $ in variable names is a gcc extension). The hardest
-# part about preparing this file is figuring out which headers to
-# include and which symbols need to be #defined to get the
-# actual data structures that pass through to the kernel system calls.
-# Some C libraries present alternate versions for binary compatibility
-# and translate them on the way in and out of system calls, but
-# there is almost always a #define that can get the real ones.
-# See types_darwin.c and types_linux.c for examples.
-#
-# * zerror_${GOOS}_${GOARCH}.go
-#
-# This machine-generated file defines the system's error numbers,
-# error strings, and signal numbers. The generator is "mkerrors.sh".
-# Usually no arguments are needed, but mkerrors.sh will pass its
-# arguments on to godefs.
-#
-# * zsyscall_${GOOS}_${GOARCH}.go
-#
-# Generated by mksyscall.pl; see syscall_${GOOS}.go above.
-#
-# * zsysnum_${GOOS}_${GOARCH}.go
