Twisted 24.3.0

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)

Bugfixes

• The documentation for twisted.web.client.CookieAgent no longer

  library modules. (#12044)

Deprecations and Removals

• twisted.web.http.Request now parses the
  [multipart/form-data]{.title-ref} using
  [email.message_from_bytes]{.title-ref}. The usage of
  [cgi.parse_multipart]{.title-ref} was removed as the
  [cgi]{.title-ref} module will be removed in Python 3.13. (#11848)
