Twisted 24.3.0 (2024-03-01)

This release supports PyPy v7.3.14.

Bugfixes

• twisted.logger.formatEvent now honors dotted method names, not just flat function names, in format strings, as it has long been explicitly documented to do. So, you will now get the expected result from [formatEvent(\"here\'s the result of calling a method at log-format time: {obj.method()}\", obj=...)]{.title-ref} (#9347)
• twisted.web.http.HTTPChannel now ignores the trailer headers provided in the last chunk of a chunked encoded response, rather than raising an exception. (#11997)
• twisted.protocols.tls.BufferingTLSTransport, used by default by twisted.protocols.tls.TLSMemoryBIOFactory, was refactored for improved performance when doing a high number of small writes. (#12011)
• twisted.python.failure.Failure now throws exception for generators without triggering a deprecation warnings on Python 3.12. (#12026)
• twisted.internet.process.Process, used by reactor.spawnProcess, now copies the parent environment when the [env=None]{.title-ref} argument is passed on Posix systems and os.posix_spawnp is used internally. (#12068)
• twisted.internet.defer.inlineCallbacks.returnValue\'s stack introspection was adjusted for the latest PyPy 7.3.14 release, allowing legacy \@inlineCallbacks to run on new PyPY versions. (#12084)

Deprecations and Removals

• twisted.trial.reporter.TestRun.startTest() is no longer called for tests with skip annotation or skip attribute for Python 3.12.1 or newer. This is the result of upstream Python gh-106584 change. The behavior is not change in 3.12.0 or older. (#12052)
