Twisted 21.2.0 (2021-02-28)

Features

• The enableSessions argument to twisted.internet.ssl.CertificateOptions now actually enables/disables OpenSSL's session cache. Also, due to session-related bugs, it defaults to False. (#9583)
• twisted.internet.defer.inlineCallbacks and ensureDeferred will now associate a contextvars.Context with the coroutines they run, meaning that ContextVar objects will maintain their value within the same coroutine, similarly to asyncio Tasks. This functionality requires Python 3.7+, or the contextvars PyPI backport to be installed for Python 3.5-3.6. (#9719, #9826)
• twisted.internet.defer.Deferred.fromCoroutine has been added. This is similar to the existing ensureDeferred function, but is named more consistently inside Twisted and does not pass through Deferreds. (#9825)
• trial now allows the @​unittest.skipIf decorator to specify that an entire test class should be skipped. (#9829)
• The twisted.python.deprecate.deprecatedKeywordParameter decorator can be used to mark a keyword paramater of a function or method as deprecated. (#9844)
• Projects using Twisted can now perform type checking against a Twisted installation, for example using mypy. (#9908)
• twisted.python.util.InsensitiveDict now fully implements MutableMapping. (#9919)
• Python 3.8 is now tested and supported. (#9955)
• Support a coroutine function in twisted.internet.task.react (#9974)
• PyPy 3.7 is now tested and supported. (#10093)

Bugfixes

• twisted.web.twcgi.CGIProcessProtocol.processEnded(...) now handles an already-finished request, for example when request.connectionLost(...) was called previously. (#9468)
• Twisted's dependency on PyHamcrest has been moved from the base package to the new "test" extra. Consequently the test extra must be installed for Twisted's test suite to pass. (#9509)
• Fixed serialization of timedelta, date, and time objects in twisted.spread. (#9716)
• twisted.internet.asyncioreactor.AsyncioSelectorReactor now raises an exception if instantiated with an event loop which is not compatible with asyncio.SelectorEventLoop. This fixes the AsyncioSelectorReactor in Python 3.8+ on Windows, where in bp-34687 the default Windows asyncio event loop was changed to ProactorEventLoop. Applications that use AsyncioSelectorReactor on Windows with Python 3.8+ must call asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy()) before instantiating and running AsyncioSelectorReactor. (#9766)
• twisted.internet.process.registerReapProcessHandler and ._BaseProcess.reapProcess will no longer raise a TypeError when processing a None PID (#9775)
• INotify will close its file descriptor if a directory is automatically removed by twisted from the watchlist because it's deleted, avoiding orphaned filedescriptors. (#9777)
• DelayedCall.reset() is now working properly with asyncioreactor (#9780)
• AsyncioSelectorReactor.seconds() now correctly returns an epoch time. (#9787)
• The _connDone parameter has been removed from twisted.internet.abstract.FileDescriptor.loseConnection()'s signature in order to match the signature in the base class twisted.internet._newtls.ConnectionMixin loseConnection(). (#9849)
• The Gtk3 reactor now runs on Wayland-only sessions (#9904)
• Descriptive error messages from twisted.internet.error are now present when running with 'python -OO'. (#9918)
• Comparator methods such as eq() now always return NotImplemented for uncomparable types. (#9919)
• When installing Twisted it now requires a minimum Python 3.5.4 version to match the version used with automated testing. This is the minimum Python version that we know that Twisted works with. (#10098)

Improved Documentation

• The narrative docs now contains the associated Twisted version and the date when they were generated. (#3945)
