Release Notes
2.0.571
- performance: use new arena allocation API to avoid
RawResult[] overhead
- performance: massively simplified how
ResultBox<T> is implemented, in particular to reduce TaskCompletionSource<T> allocations
- performance: fix sync-over-async issue with async call paths, and fix the SemaphoreSlim problems that this uncovered
- performance: re-introduce the unsent backlog queue, in particular to improve async performance
- performance: simplify how completions are reactivated, so that external callers use their originating pool, not the dedicated IO pools (prevent thread stealing)
- fix: update Pipelines.Sockets.Unofficial to prevent issue with incorrect buffer re-use in corner-case
- fix:
KeyDeleteAsync could, in some cases, always use DEL (instead of UNLINK)
- fix: last unanswered write time was incorrect
- change: use higher
Pipe thresholds when sending
2.0.519
- adapt to late changes in the RC streams API (#983, #1007)
- documentation fixes (#997, #1005)
- build: switch to SDK 2.1.500
2.0.513
- fix #961 - fix assembly binding redirect problems; IMPORTANT: this drops to an older
System.Buffers version - if you have manually added redirects for 4.0.3.0, you may need to manually update to 4.0.2.0 (or remove completely)
- fix #962 - avoid NRE in edge-case when fetching bridge
2.0.505
- fix #943 - ensure transaction inner tasks are completed prior to completing the outer transaction task
- fix #946 - reinstate missing
TryParse methods on RedisValue
- fix #940 - off-by-one on pre-boxed integer cache (NRediSearch)
2.0.495
- 2.0 is a large - and breaking - change
The key focus of this release is stability and reliability.
- HARD BREAK: the package identity has changed; instead of
StackExchange.Redis (not strong-named) and StackExchange.Redis.StrongName (strong-named), we are now
only releasing StackExchange.Redis (strong-named). This is a binary breaking change that requires consumers to be re-compiled; it cannot be applied via binding-redirects
- HARD BREAK: the platform targets have been rationalized - supported targets are .NETStandard 2.0 (and above), .NETFramework 4.6.1 (and above), and .NETFramework 4.7.2 (and above)
(note - the last two are mainly due to assembly binding problems)
- HARD BREAK: the profiling API has been overhauled and simplified; full documentation is provided here
- SOFT BREAK: the
PreserveAsyncOrder behaviour of the pub/sub API has been deprecated; a new API has been provided for scenarios that require in-order pub/sub handling -
the Subscribe method has a new overload without a handler parameter which returns a ChannelMessageQueue, which provides async ordered access to messsages)
- internal: the network architecture has moved to use
System.IO.Pipelines; this has allowed us to simplify and unify a lot of the network code, and in particular
fix a lot of problems relating to how the library worked with TLS and/or .NETStandard
- change: as a result of the
System.IO.Pipelines change, the error-reporting on timeouts is now much simpler and clearer; the timeouts documentation has been updated
- removed: the
HighPriority (queue-jumping) flag is now deprecated
- internal: most buffers internally now make use of pooled memory;
RedisValue no longer pre-emptively allocates buffers
- internal: added new custom thread-pool for handling async continuations to avoid thread-pool starvation issues
- intenal: all IL generation has been removed; the library should now work on platforms that do not allow runtime-emit
- added: asynchronous operations now have full support for reporting timeouts
- added: new APIs now exist to work with pooled memory without allocations -
RedisValue.CreateFrom(MemoryStream) and operator support for Memory<byte> and ReadOnlyMemory<byte>; and IDatabase.StringGetLease[Async](...), IDatabase.HashGetLease[Async](...), Lease<byte>.AsStream())
- added: “streams” support (thanks to ttingen for their contribution)
- various missing commands / overloads have been added;
Execute[Async] for additional commands is now available on IServer
- fix: a lot of general bugs and issues have been resolved
- ACCIDENTAL BREAK:
RedisValue.TryParse was accidentally ommitted in the overhaul; this has been rectified and will be available in the next build
a more complete list of issues addressed can be seen in this tracking issue
Note: we currently have no plans to do an additional 1.* release. In particular, even though there was a 1.2.7-alpha build on nuget, we do not currently have
plans to release 1.2.7.
1.2.6
- fix change to
cluster nodes output when using cluster-enabled target and 4.0+ (see redis #4186
1.2.5
- critical fix: “poll mode” was disabled in the build for net45/net60 - impact: IO jams and lack of reader during high load
1.2.4
- fix: incorrect build configuration (#649)
1.2.3
- fix: when using
redis-cluster with multiple replicas, use round-robin when selecting replica (#610)
- add: can specify
NoScriptCache flag when using ScriptEvaluate to bypass all cache features (always uses EVAL instead of SCRIPT LOAD and EVALSHA) (#617)
1.2.2 (preview):
- UNAVAILABLE: .NET 4.0 support is not in this build, due to a build issue - looking into solutions
- add: make performance-counter tracking opt-in (
IncludePerformanceCountersInExceptions) as it was causing problems (#587)
- add: can now specifiy allowed SSL/TLS protocols (#603)
- add: track message status in exceptions (#576)
- add:
GetDatabase() optimization for DB 0 and low numbered databases: IDatabase instance is retained and recycled (as long as no asyncState is provided)
- improved connection retry policy (#510, #572)
- add
Execute/ExecuteAsync API to support “modules”; more info
- fix: timeout link fixed re /docs change (below)
NRediSearch added as exploration into “modules”
Other changes (not library related)
- (project) refactor /docs for github pages
- improve release note tracking
- rework build process to use csproj
1.2.1
- fix: avoid overlapping per-endpoint heartbeats
1.2.0
1.2.0-alpha1
- add: GEO commands (#489)
- add: ZADD support for new NX/XX switches (#520)
- add: core-clr preview support improvements
1.1.608
- fix: bug with race condition in servers indexer (related: 1.1.606)
1.1.607
- fix: ensure socket-mode polling is enabled (.net)
1.1.606
- fix: bug with race condition in servers indexer
and the rest
(I’m happy to take PRs for change history going back in time)
