v3.3.0.RELEASE

Reactor-Core 3.3.0.RELEASE is part of Dysprosium-RELEASE Release Train.

This release note covers the first GA release of the 3.3.x cycle, and as such describes the changes from the perspective of a 3.2.x to 3.3.0 comparison.

See also release notes from 3.2.12, 3.2.11, 3.2.10 and 3.2.9 for changes that were inherited from the 3.2.x maintenance releases.

This release is a big opportunity to polish the APIs and some behaviors with less restriction than maintenance releases.

🌟 It also introduces a few new features, the highlight of which is the BoundedElasticScheduler:
this one has evolved from the ElasticScheduler and is intended as a future replacement for it.
A cap can be put on the number of threads such a scheduler can spawn. After that cap is reached, further task submissions are deferred (being enqueued) up to a second global limit on enqueued tasks (optionally unbounded).

💥 Known issues

• (since 3.3.0.M2) There are regressions with Flux.replay/cache hanging or delivering wrong data (tracked in #2030)

⚠️ Update considerations and deprecations

• (from RC1:)
• A few Mono operators have slightly changed their behavior in regards to how when they propagate onNext: they could trigger onError after onNext, which is not permitted in Mono.
  • Mono#usingWhen now waits for the async complete handler termination before propagating onNext (#1832)
  • Mono#using similarly avoids triggering onNext+onError if cleanup fails (#1853)
  • Mono#doOnTerminate now acts similarly to doOnSuccess, executing the side effect before the onNext is propagated downstream (#1752)
• Mono#do[On|After]SuccessOrError has been deprecated and marked for removal in 3.4 (#1854)
• usingWhen API has been polished, and some variants deprecated for removal in 3.4 (#1687)
  • A new overload has been introduced that uses BiFunction for error handler (exposing the failure that causes "rollback")
  • A single-handler version has been added to Mono for alignment with Flux. This is the simplest case: same handler for complete, error and cancel terminations.
  • All other overloads have been deprecated. Goal is to favor either the simple 1-handler-covers-all case OR force users to be explicit about ALL possible terminations.
• (from M3:)
• #1742 Processors and Kotlin extensions deprecations
• the WorkQueueProcessor and TopicProcessor have been marked as deprecated for 3.3.x and will be removed in 3.4
• have been deprecated, due to underlying use of Unsafe
• Recommended core alternative is to combine EmitterProcessor and publishOn
• the Kotlin extensions are deprecated in core and replaced by a dedicated project/repo, reactor-kotlin-extensions
• in both cases, the deprecated classes don't appear in the generated javadoc jar
• #1764 Deprecated method Schedulers.Factory#decorateExecutorService has been removed
• #1669 All onBackpressureBuffer(maxSize+error) variants now delay errors
• In debug mode, most of the original stacktrace is artificially moved at the end of the exception's output, after the "backtrace" (#1781)
• #1745 compose() has been deprecated and renamed transformDeferred()
• deprecated operator will be removed in 3.4
• #1451 Dematerialize has been reworked and now expects 1 request per upstream Signal
• This avoids onNext events to be emitted only when the subsequent signal is ready upstream
• This also means that in order to get a terminal signal like onComplete signal, the corresponding Signal must be explicitly requested from upstream (one extra request(1))
• (from M2:)
• Exceptions are now unwrapped (Exceptions#unwrap) in most sources that immediately produce an error, acting like a Callable (b6f4d29)
• Moved reactor-tools sources into the core repository (#1731)

✨ New features and improvements

• 🌟 Added a boundedElastic Scheduler that caps number of threads and scales to 0 (#1804)
  • global singleton also cap deferred tasks past the thread limit to 100K (32d2a29)
  • thread cap and task queue capacity can be configured separately, the later can even be unbounded
• Add windowUntilChanged operator, ensure the stateful predicate is subscriber-specific and cleaned on cancel (#1850, #1901)
• Improve the naming (eg. scan(Attr.NAME) or toString) of global singleton Schedulers (#1885, #1886)
  • for instance, instead of parallel(parallel) this is now Schedulers.parallel()
• Improvements around subscription recursivity / subscribe loop performance (#1882)
• Avoid extra lastAssembly by using CorePublisher where possible (#1883)
• (from RC1:)
• Due to a few Throwable constants, class references could leak in multi-classloader environments. This is now avoided by skipping the filling of the stacktrace (#1872)
• Add BufferUntilChanged operator (#1706, bb5b2bb)
• Added new StepVerifier API to subscribe to source and verify it later (#1848, b2ce5fe)
• (from M3:)
• Add "VirtualTimeScheduler#getScheduledTaskCount()" (#1746)
• #1763 Flux.parallel now uses Schedulers.DEFAULT_POOL_SIZE (which can be overridden by system property)
• #1767 Add ParallelFlux#then to compose on parallel termination
• #1722 Make sure ElasticScheduler.CachedService gets disposed
• #1798 Use bounded wildcard in error(Supplier)
• Polish flux metrics (#1802)
  • see also the other commits linked in that PR
• Actually record executor service metrics to Micrometer (#1795)
• Add a Context-aware {Mono,Flux}.deferWithContext (#1819)
• Eliminate subscribe from stack by optimizing the "tail calls" (#1761, #1826)
• #1416 Add lambda subscribe variants with a context
• (from M2:)
• Avoid triggering Context lookups in error sources (4f2bc7a)
• Extended blockHound whitelist
  • all ScheduledExecutor offer (95c0884)
  • DelayedWorkQueue#take (#1726)
• Remove unnecessary volatile with UnicastProcessor fusion (c86db5a)
• Improved cache eviction in ElasticScheduler (#1700)
• (from M1:)
• Compatibility with projects using the Java Module System (JPMS) has been improved by declaring an official Automatic-Module-Name (reactor.core and reactor.test, #1641, #1692)
• The CorePublisher interface has been introduced to distinguish Publisher from reactor (#1527)
• Add a simplified API for wrapping scheduled tasks (#1546)
• Add an API-preserving hide() method to ConnectableFlux (#1577)
• [reactor-test] Added hasDiscardedMatching method in StepVerifier (#1509)
• [reactor-test] Add ToStringConverter and Extractor to StepVerifierOptions (#1558)
  • This allows to override the natural toString representation of classes that are known to have an obscure representation, as well as extracting such objects that would be nested in containers like a Collection, Tuple2, Signal, ...
• Reworked the format of "backtraces" (#1672, #1702)
  • Backtraces are the additional callsite information captured by debug mode and checkpoint and appended to onError Throwable as a suppressed exception
• Reactor now integrates into Blockhound 1.0.0.M3 using the SPI on reactor side instead of programmatic explicit registration on blockhound side (#1682, #1690)

🪲 Bug fixes

• (from M2:)
• Avoid unbounded Flux.replay request with bounded subscribers (#1185)
• Removed "checkpoint" prefix in backtraces from return-only callsites (#1740)
