v3.2.5.RELEASE

This is the 6th release of Reactor 3.2, part of Californium-SR4 Release Train.

This is a recommended update for all Reactor 3 users, containing a few improvements, a new operator (switchOnFirst) and documentation improvements (the biggest being a switch from PNG marbles to SVG marbles).

⚠️ Update considerations and deprecations

• ⭐ The marble diagrams are now in SVG format instead of PNG. They are also embedded in the sources/javadoc jars.
  • This should allow anybody wanting to contribute to diagrams to do so more easily
  • Embedding the diagrams (doc-files) means we don't rely on being online to fetch and display them.
  • It also greatly facilitates the releasing process of a change to a diagram / new diagram.
  • Be aware that some IDEs might have a bit of trouble with size of SVG when displaying "documentation popups" (eg. IntelliJ IDEA prior to 2018.3.1)

✨ New features and improvements

• Add subscribeCount() to PublisherProbe (#1447)
• Converted eager toString call from index operator to lazy (#1453)
• Add Kotlin extension switchIfEmpty with deferred execution (#1460)
• Add onErrorContinue to Mono API (#1458)
• Add putNonNull and size methods to Context (#1442)
• ⭐ Add new switchOnFirst operator to Flux (#1423)
• Optimize assembly tracing (#1466, #1483)
• Polish Mono Kotlin extensions and functions fixes (#1475)

📖 Documentation, Tests and Build

• [doc] Various fixes to the javadoc/reference guide (bad method names, indentation...) (#1471, #1473)
• [build] Add Micrometer to OSGI optional bundles (#1470)
• [build] Improve build compatibility with JDK11 (JRuby, asciidoctor, etc...) (#1477, #1479, #1480)
• [doc] Big rework of the integration of marbles into the javadoc (#1390):
  • Rework marble diagrams into SVG
  • Marble SVGs now directly in doc-files folder
  • Added a graphical convention document in docs/svg
  • Verified, reworked and optimized all marbles

v3.1.14.RELEASE

This is the 15th release of Reactor 3.1, part of BISMUTH-SR15 Release Train.

This release contains minor new API in the Context class.

✨ New features and improvements

• Added putNonNull and size methods to Context (#1442)

-don't use- v3.2.4.RELEASE

-This release is superseded by v3.2.5.RELEASE-

It has been built using JDK11 and the javadoc jars are non-functional, especially when served from the reactor website.

-don't use- v3.1.13.RELEASE

-This release is superseded by v3.1.14.RELEASE-

v3.2.3.RELEASE

This is the 4th release of Reactor 3.2, part of Californium-SR3 Release Train.

This is a recommended update for all Reactor 3.2 users.

⚠️ Update considerations and deprecations

• ✨ Add ability to multi-decorate backing ExecutorServices (#1408, #1409)
  • This replaces the Factory method that is now deprecated (but applied as the last decorator)
  • Decorators are keyed by a String, allowing for easy identification and removal of specific decorators and good behavior when multiple libraries need to install a decorator
• 🐞 Mono.fromFuture/Mono.fromCompletionStage now correctly detects when the future is completed AFTER the Mono has been cancelled (#1414)
  • Any value is ignored by this point. Exceptions are still propagated except CancellationException
  • The later means that one can also safely cancel the source Future itself in a doOnCancel

✨ New features and improvements

• StepVerifier now provides more details on unexpected termination during no-event (#1440)
• Reactor-provided Scheduler backed by an ExecutorService can now be instrumented with Micrometer (#1201)
• The Schedulers.enableMetrics() method enables this
• Only state of the executor (number of tasks in the queue for instance) is instrumented for now, not duration of the tasks.
• Custom-made Scheduler implementations can apply the same decorator (and any registered decorator) via the new Schedulers.decorateExecutorService method
• Make expectAccessibleContext work with initialContext from StepVerifier when just asserting a scalar source without operators (#1417)

🪲 Bug fixes

• Disposed worker also rejects scheduling a 0-period task (#1411)
• Ensure METER_FLOW_DURATION always have exception tag (would otherwise break assumptions of a few instrumentation providers) (#1425)
• Fixed request accounting in onBackpressureLatest (#1430)

📖 Documentation, Tests and Build

• Various documentation typos have been fixed (#1420, #1419, #1424, #1427,
• The wording about guarantees enforced by the Scheduler#createWorker interface has been clarified not to always include ordering (#1421)
• [test] Attempt to fix flaky test distinctUntilChanged*DoesntRetainObjects (#1428)
• [test] Better evaluation of bufferWhen cancel/drain race (c5a93be)

v3.1.12.RELEASE

This is the 13th release of Reactor 3.1, part of Bismuth-SR14 Release Train.

This is a recommended update for all Reactor 3.1 users.

✨ New features and improvements

• Make expectAccessibleContext work with initialContext from StepVerifier (#1417)
• Even though this method aims at checking was is readable in the context, if there is no chain of operators and the Publisher is just a source one, then StepVerifier now ties back to the Context provided in the options.

🪲 Bug fixes

• Fix request accounting in onBackpressureLatest (#1430)
