Changelog from v3.0.1 and up. Prior changes don't have a changelog.

v3.8.1

  • Fixed NewCluster not returning an error if it can't connect to any of the redis instances given. (#319)

  • Fix deadlock in Cluster when using DoSecondary. (#317)

  • Fix parsing for CLUSTER SLOTS command, which changed slightly with redis 7.0. (#322)

v3.8.0

New

  • Add PoolMaxLifetime option for Pool. (PR #294)

Fixes And Improvements

  • Switched to using errors package, rather than golang.org/x/xerrors. (PR #300)

  • Switch to using Github Actions from travis. (PR #300)

  • Fixed IPv6 addresses breaking Cluster. (Issue #288)

  • Release the RLock in Sentinel's Do. (PR #272)

v3.7.0

New

  • Add FallbackToUndelivered option to StreamReaderOpts. (PR #244)

  • Add ClusterOnInitAllowUnavailable. (PR #247)

Fixes and Improvements

  • Fix reading a RESP error into a *interface{} panicking. (PR #240)

v3.6.0

New

  • Add Tuple type, which makes unmarshaling EXEC and EVAL results easier.

  • Add PersistentPubSubErrCh, so that asynchronous errors within PersistentPubSub can be exposed to the user.

  • Add FlatCmd method to EvalScript.

  • Add StreamEntries unmarshaler to make unmarshaling XREAD and XREADGROUP results easier.

Fixes and Improvements

  • Fix wrapped errors not being handled correctly by Cluster. (PR #229)

  • Fix PersistentPubSub deadlocking when a method was called after Close. (PR #230)

  • Fix StreamReader not correctly handling the case of reading from multiple streams when one is empty. (PR #224)

v3.5.2

  • Improve docs for WithConn and PubSubConn.

  • Fix PubSubConn's Subscribe and PSubscribe methods potentially mutating the passed in array of strings. (Issue #217)

  • Fix StreamEntry not properly handling unmarshaling an entry with a nil fields array. (PR #218)

v3.5.1

  • Add EmptyArray field to MaybeNil. (PR #211)

  • Fix Cluster not properly re-initializing itself when the cluster goes completely down. (PR #209)

v3.5.0

Huge thank you to @nussjustin for all the work he's been doing on this project, this release is almost entirely his doing.

New

  • Add support for TYPE option to Scanner. (PR #187)

  • Add Sentinel.DoSecondary method. (PR #197)

  • Add DialAuthUser, to support username+password authentication. (PR #195)

  • Add Cluster.DoSecondary method. (PR #198)

Fixes and Improvements

  • Fix pipeline behavior when a decode error is encountered. (PR #180)

  • Fix Reason in PoolConnClosed in the case of the Pool being full. (PR #186)

  • Refactor PersistentPubSub to be cleaner, fixing a panic in the process. (PR #185, Issue #184)

  • Fix marshaling of nil pointers in structs. (PR #192)

  • Wrap errors which get returned from pipeline decoding. (PR #191)

  • Simplify and improve pipeline error handling. (PR #190)

  • Dodge a []byte allocation when in StreamReader.Next. (PR #196)

  • Remove excess lock in Pool. (PR #202)

v3.4.2

  • Fix alignment for atomic values in structs (PR #171)

  • Fix closing of sentinel instances while updating state (PR #173)

v3.4.1

  • Update xerrors package (PR #165)

  • Have cluster Pools be closed outside of lock, to reduce contention during failover events (PR #168)

v3.4.0

  • Add PersistentPubSubWithOpts function, deprecating the old PersistentPubSub function. (PR #156)

  • Make decode errors a bit more helpful. (PR #157)

  • Refactor Pool to rely on its inner lock less, simplifying the code quite a bit and hopefully speeding up certain actions. (PR #160)

  • Various documentation updates. (PR #138, Issue #162)

v3.3.2

  • Have resp2.Error match with a resp.ErrDiscarded when using errors.As. Fixes EVAL, among probably other problems. (PR #152)

v3.3.1

  • Use xerrors internally. (PR #113)

  • Handle unmarshal errors better. Previously an unmarshaling error could leave the connection in an inconsistent state, because the full message wouldn't get completely read off the wire. After a lot of work, this has been fixed. (PR #127, #139, #145)

  • Handle CLUSTERDOWN errors better. Upon seeing a CLUSTERDOWN, all commands will be delayed by a small amount of time. The delay will be stopped as soon as the first non-CLUSTERDOWN result is seen from the Cluster. The idea is that, if a failover happens, commands which are incoming will be paused long enough for the cluster to regain it sanity, thus minimizing the number of failed commands during the failover. (PR #137)

  • Fix cluster redirect tracing. (PR #142)

v3.3.0

New

  • Add trace package with tracing callbacks for Pool and Cluster. (Sentinel coming soon!) (PR #100, PR #108, PR #111)

  • Add SentinelAddrs method to Sentinel (PR #118)

  • Add DialUseTLS option. (PR #104)

Fixes and Improvements

  • Fix NewSentinel not handling URL AUTH parameters correctly (PR #120)

  • Change DefaultClientFunc's pool size from 20 to 4, on account of pipelining being enabled by default. (Issue #107)

  • Reuse reflect.Value instances when unmarshaling into certain map types. (PR #96).

  • Fix a panic in FlatCmd. (PR #97)

  • Reuse field name string when unmarshaling into a struct. (PR #95)

  • Reduce PubSub allocations significantly. (PR #92 + Issue #91)

  • Reduce allocations in Conn. (PR #84)

v3.2.3

  • Optimize Scanner implementation.

  • Fix bug with using types which implement resp.LenReader, encoding.TextMarshaler, and encoding.BinaryMarshaler. The encoder wasn't properly taking into account the interfaces when counting the number of elements in the message.

v3.2.2

  • Give Pool an ErrCh so that errors which happen internally may be reported to the user, if they care.

  • Fix PubSubConn's deadlock problems during Unsubscribe commands.

  • Small speed optimizations in network protocol code.

v3.2.1

  • Move benchmarks to a submodule in order to clean up go.mod a bit.

v3.2.0

  • Add StreamReader type to make working with redis' new Stream functionality easier.

  • Make Sentinel properly respond to Client method calls. Previously it always created a new Client instance when a secondary was requested, now it keeps track of instances internally.

  • Make default Dial call have a timeout for connect/read/write. At the same time, normalize default timeout values across the project.

  • Implicitly pipeline commands in the default Pool implementation whenever possible. This gives a throughput increase of nearly 5x for a normal parallel workload.

v3.1.0

  • Add support for marshaling/unmarshaling structs.

v3.0.1

  • Make Stub support Pipeline properly.
