twisted - Towncrier 25.5.0

Twisted 25.5.0 (2025-06-07)

Bugfixes

• twisted.internet.runner.procmon.ProcessMonitor: startProcess() catches exceptions raised by reactor.spawnProcess() and attempts to restart the failed process. (#12421)

Deprecations and Removals

• twisted.trial.unittest.TestCase.deferSetUp, twisted.trial.unittest.TestCase.deferTestMethod, twisted.trial.unittest.TestCase.deferTearDown, and twisted.trial.unittest.TestCase.deferRunCleanups were removed and converted to private methods. These functions expose so much of the internal structure of TestCase that it makes the code hard to change. (#12388)
• twisted.internet.defer.waitForDeferred twisted.internet.defer.deferredGenerator have been removed. They have been deprecated since Twisted 15.0.0 (#12404)
• twisted.internet.defer.Deferred.callbacks attribute has been deprecated. (#12407)

Misc

• #12375, #12383, #12384, #12392, #12419, #12434, #12440, #12441

Conch

Bugfixes

• twisted.conch.client.direct.SSHClientTransport.verifyHostKey no longer crashes with an encoding error while attempting to verify the peer's IP address. This means that the conch command-line tool will no longer fail host key verification with 'bad host key' when using a known hosts file containing only plaintext, rather than hashed, hostnames. (#12414)

Web

Features

• The twisted.web.websockets module has been added, adding a websockets server and client based on the wsproto library. (#4173)
• twisted.web.server.Site can now be created with a parsePOSTFormSubmission=False parameter to disable parsing of HTTP request bodies. (#12412)

Bugfixes

• twisted.web.http.Request.addCookie now supports the none value for cookie's samesite attribute. (#10088)
• twisted.web.http.Request.requestReceived now handles multiple files in multipart/form-data with the same "name" parameter. This was a regression introduced in Twisted 24.3.0. (#12423) (#12423)

Improved Documentation

• An error in the example for using a Resource object in th documentation on Configuring and Using the Twisted Web Server has been correctd.

Furthermore, a number of references to "strings" where "bytes" where expected has been adjusted. (#12410)

Mail

Twisted 24.10.0 (2024-10-28)

Features

• Python 3.13 is now supported. (#11750)
• twisted.internet.defer.succeed() is significantly faster, and awaiting Deferred has also been sped up. (#12225)
• twisted.python.failure.Failure creation no longer records the place where it was created. This reduces creation time by 60% at least, thereby speeding up Deferred error handling. (#12230)
• twisted.internet.defer.Deferred no longer removes the traceback object from Failures. This may result in more objects staying in memory if you don't clean up failed Deferreds, but it speeds up error handling and enables improvements to traceback reporting. (#12234)
• twisted.internet.defer APIs are 2%-4% faster in many cases. (#12237)
• twisted.internet.defer.Deferred runs callbacks with chained Deferreds a little faster. (#12284)
• The reactor now will use a little less CPU when events have been scheduled with callLater(). (#12286)
• Creation of twisted.python.failure.Failure is now faster. (#12288)
• twisted.web.server is 1-2% faster in some cases. (#12318)

Bugfixes

• Fixed unreleased regression caused by PR 12109. (#12279)
• twisted.logger.eventAsText can now format the output having types/classes as input. This was a regression introduced in Twisted 24.3.0. (#12323)
• twisted.internet.endpoints.clientFromString for TLS endpoints with "bindAddress=" no longer crashes during connect. twisted.internet.endpoints.HostnameEndpoint() no longer crashes when given a bindAddress= argument that is just a string, and that argument now accepts either address strings or (address, port) tuples. (#12325)
• The URLs from README and pyproject.toml were updated. (#12327)

Misc

• #11236, #12060, #12062, #12099, #12219, #12290, #12296, #12305, #12329, #12331, #12339

Bugfixes

• twisted.conch tests no longer rely on OpenSSH supporting DSA keys, fixing compatibility with OpenSSH >= 9.8. (#12273)
• twisted.conch.ssh.SSHCiphers no longer supports the cast128-ctr, cast128-cbc, blowfish-ctr, and blowfish-cbc ciphers. The Blowfish and CAST5 ciphers were removed as they were deprecated by the Python cryptography library.``` (#12308)

Misc

• #12313

Web

Features

• The twisted.web HTTP server and client now reject HTTP header names containing whitespace or other invalid characters by raising twisted.web.http_headers.InvalidHeaderName, improving compliance with RFC 9110. As a side effect, the server is slightly faster. (#12191)
• twisted.web.client and twisted.web.server now disable the Nagle algorithm (enable TCP_NODELAY), reducing the latency of small HTTP queries. (#12311)

Bugfixes

• twisted.web's HTTP/1.1 server now rejects header values containing a NUL byte with a 400 error, in compliance with RFC 9110. (#12228)

twisted - Twisted 24.7.0

Twisted 24.7.0 (2024-08-08)

24.7.0.rc2 fixed an unreleased regression caused by PR 12109. (#12279) No other changes since 24.7.0.rc2

Features

• twisted.protocols.ftp now supports the IPv6 extensions defined in RFC 2428. (#9645)
• twisted.internet.defer.inlineCallbacks can now yield a coroutine. (#9972)
• twisted.python._shellcomp.ZshArgumentsGenerator was updated for Python 3.13. (#12065)
• twisted.web.wsgi request environment now contains the peer port number as REMOTE_PORT. (#12096)
• twisted.internet.defer.Deferred.callback() and twisted.internet.defer.Deferred.addCallbacks() no longer use assert to check the type of the arguments. You should now use type checking to validate your code. These changes were done to reduce the CPU usage. (#12122)
• Added two new methods, twisted.logger.Logger.failuresHandled and twisted.logger.Logger.failureHandler, which allow for more concise and convenient handling of exceptions when dispatching out to application code. The former can arbitrarily customize failure handling at the call site, and the latter can be used for performance-sensitive cases where no additional information needs to be logged. (#12188)
• twisted.internet.defer.Deferred.addCallback now runs about 10% faster. (#12223)
• twisted.internet.defer.Deferred error handling is now faster, taking 40% less time to run. (#12227)

Bugfixes

• Fixed unreleased regression caused by PR #12109. (#12279)
• twisted.internet.ssl.Certificate.repr can now handle certificates without a common name (CN) in the certificate itself or the signing CA. (#5851)
• Type annotations have been added to twisted.conch.interfaces.IKnownHostEntry and its implementations, twisted.conch.client.knownhosts.PlainHost and twisted.conch.client.knownhosts.HashedHost, correcting a variety of type confusion issues throughout the conch client code. (#9713)
• twisted.python.failure.Failure once again utilizes the custom pickling logic it used to in the past. (#12112)
• twisted.conch.client.knownhosts.KnownHostsFile.verifyHostKey no longer logs an exception when automatically adding an IP address host key, which means the interactive conch command-line no longer will either. (#12141)

Improved Documentation

• The IRC server example found in the documentation was updated for readability. (#12097)
• Remove contextvars from list of optional dependencies. (#12128)
• The documentation for installing Twisted was moved into a single page. (#12145)
• The project's compatibility policy now clearly indicates that the GitHub Actions test matrix defines the supported platforms. (#12167)
• Updated imap4client.py example, it no longer references Python 2. (#12252)

Deprecations and Removals

• twisted.internet.defer.returnValue has been deprecated. You can replace it with the standard return statement. (#9930)
• The twisted-iocpsupport is no longer a hard dependency on Windows. The IOCP support is now installed together with the other Windows soft dependencies via twisted[windows-platform]. (#11893)
• twisted.python.deprecate helper function will now always strip whitespaces from the docstrings. This is done to have the same behaviour as with Python 3.13. (#12063)
• twisted.conch.manhole.ManholeInterpreter.write, twisted.conch.manhole.ManholeInterpreter.addOutput, twisted.mail.imap4.IMAP4Server.sendUntaggedResponse async argument, deprecated since 18.9.0, has been removed. (#12130)
• twisted.web.soap was removed. The SOAP support was already broken, for at least the last 4 years. The SOAP support in Twisted has no active maintainer. (#12146)

Misc

• #11744, #11771, #12113, #12154, #12169, #12179, #12193, #12195, #12197, #12215, #12221, #12243, #12249, #12254, #12259, #12669

Conch

Bugfixes ~~~~~~~~

• twisted.conch.insults.window.Widget.functionKeyReceived now dispatches functional key events to corresponding func_KEYNAME methods, where KEYNAME can be F1, F2, HOME, UP_ARROW etc. This is a regression introduced with #8214 in Twisted 16.5.0, where events changed from const objects to bytestrings in square brackets like [F1]. (#12046)

Web

Features ~~~~~~~~

• twisted.web.agent.Agent now allows duplicate Content-Length headers having the same value, per RFC 9110 section 8.6. It is otherwise more strict when parsing Content-Length header values. (#9064)
• twisted.web.client.HTTPConnectionPool used by HTTP clients now runs faster by using a little less CPU. (#12108)
• twisted.web.http_headers now uses less CPU, making a small HTTP client request 10% faster or so. (#12116)
• twisted.web's HTTP/1.1 server now runs a little faster, with about 10% lower CPU overhead. (#12133)
• twisted.web's HTTP 1.1 server is an additional 5% faster. (#12155)

Bugfixes ~~~~~~~~

• twisted.web.util.redirectTo now HTML-escapes the provided URL in the fallback response body it returns (GHSA-cf56-g6w6-pqq2, CVE-2024-41810). (#9839)
• twisted.web.http.IMATEAPOT was added and returns I'm a teapot as default message for the status code 418, as defined in RFC 2324 section 2.3.2. (#12104)
• The HTTP 1.0/1.1 server provided by twisted.web is now more picky about the first line of a request, improving compliance with RFC 9112. (#12233)
• The HTTP 1.0/1.1 server provided by twisted.web now contains the characters set of HTTP header names, improving compliance with RFC 9110. (#12235)
• The HTTP 1.0 and 1.1 server provided by twisted.web could process pipelined HTTP requests out-of-order, possibly resulting in information disclosure (CVE-2024-41671/GHSA-c8m8-j448-xjx7) (#12248)
• twisted.web.util.redirectTo now HTML-escapes the provided URL in the fallback response body it returns (GHSA-cf56-g6w6-pqq2). The issue is being tracked with CVE-2024-41810. (#12263)

Improved Documentation ~~~~~~~~~~~~~~~~~~~~~~

• Fix ReverseProxyResource example in developer guide. (#12152)

Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~

• twisted.web.util.ChildRedirector, which has never worked on Python 3, has been removed. (#9591)
• twisted.web.http.Request.setResponseCode() no longer validates the types of inputs; we encourage you to use a type checker like mypy to catch these sort of errors. The long-deprecated twisted.web.server.string_date_time() and twisted.web.server.date_time_string() APIs were removed altogether. (#12133)
• twisted.web.http.HTTPClient is now deprecated in favor of twisted.web.client.Agent (#12158)

• Added two new methods, twisted.logger.Logger.failuresHandled and twisted.logger.Logger.failureHandler, which allow for more concise and convenient handling of exceptions when dispatching out to application code. The former can arbitrarily customize failure handling at the call site, and the latter can be used for performance-sensitive cases where no additional information needs to be logged. (#12188)
• twisted.internet.defer.Deferred.addCallback now runs about 10% faster. (#12223)

• Updated imap4client.py example, it no longer references Python 2. (#12252)

Deprecations and Removals

• twisted.internet.defer.returnValue has been deprecated. You can replace it with the standard return statement. (#9930)
• The twisted-iocpsupport is no longer a hard dependency on Windows. The IOCP support is now installed together with the other Windows soft dependencies via twisted[windows-platform]. (#11893)
• twisted.python.deprecate helper function will now always strip whitespaces from the docstrings. This is done to have the same behaviour as with Python 3.13. (#12063)
• twisted.conch.manhole.ManholeInterpreter.write, twisted.conch.manhole.ManholeInterpreter.addOutput, twisted.mail.imap4.IMAP4Server.sendUntaggedResponse async argument, deprecated since 18.9.0, has been removed. (#12130)

Conch

Bugfixes ~~~~~~~~

• twisted.conch.insults.window.Widget.functionKeyReceived now dispatches functional key events to corresponding func_KEYNAME methods, where KEYNAME can be F1, F2, HOME, UP_ARROW etc. This is a regression introduced with #8214 in Twisted 16.5.0, where events changed from const objects to bytestrings in square brackets like [F1]. (#12046)

Web

Features ~~~~~~~~

• twisted.web.agent.Agent now allows duplicate Content-Length headers having the same value, per RFC 9110 section 8.6. It is otherwise more strict when parsing Content-Length header values. (#9064)

twisted - 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)

Twisted 23.10.0 (2023-10-31)

No changes since 23.10.0.rc1.

Features

• twisted.python.filepath.FilePath and related classes (twisted.python.filepath.IFilepath, twisted.python.filepath.AbstractFilePath, twisted.python.zippath.ZipPath, and twisted.python.zippath.ZipArchive) now have type annotations. Additionally, FilePath is now generic, describing its mode, so you can annotate variables as FilePath[str] or FilePath[bytes] depending on the types that you wish to get back from the 'path' attribute and related methods like 'basename'. (#11822)
• When using CPython, functions wrapped by twisted.internet.defer.inlineCallbacks can have their arguments and return values freed immediately after completion (due to there no longer being circular references). (#11885)

Bugfixes

• Fix TypeError on t.i.cfreactor due to 3.10 type annotation syntax (#11965)
• Fix the type annotations of DeferredLock.run, DeferredSemaphore.run, maybeDeferred, ensureDeferred, inlineCallbacks and fromCoroutine that used to return Deferred[Any] to return the result of the passed Coroutine/Coroutine function (#11985)
• Fixed significant performance overhead (CPU and bandwidth) when doing small writes to a TLS transport. Specifically, small writes to a TLS transport are now buffered until the next reactor iteration. (#11989)
• fix mypy due to hypothesis 6.85 (#11995)

Improved Documentation

• The search and version navigation for the documentation hosted on Read The Docs was fixed. This was a regression introduced with 23.8.0. (#12012)

Web

Bugfixes ~~~~~~~~

• In Twisted 16.3.0, we changed twisted.web to stop dispatching HTTP/1.1 pipelined requests to application code. There was a bug in this change which still allowed clients which could send multiple full HTTP requests in a single TCP segment to trigger asynchronous processing of later requests, which could lead to out-of-order responses. This has now been corrected and twisted.web should never process a pipelined request over HTTP/1.1 until the previous request has fully completed. (CVE-2023-46137, GHSA-cq7q-gv5w-rwx2) (#11976)

twisted - Twisted 23.8.0

Twisted 23.8.0. (2023-08-28)

This is the last release with support for Python 3.7.

No changes since 23.8.0.rc1.

Features

• reactor.spawnProcess() now uses posix_spawnp when possible, making it much more efficient (#5710)
• Twisted now officially supports Python 3.11. (#10343)
• twisted.internet.defer.Deferred.fromFuture now has a more precise type annotation. (#11753)
• twisted.internet.defer.ConcurrencyPrimitive.aexit_ now has a more precise type annotation. (#11795)
• twisted.internet.defer.race has been added as a way to get the first available result from a list of Deferreds. (#11817)
• The CI suite was updated to execute the tests using a Python 3.12 pre-release (#11857)

Bugfixes

• twisted.conch.scripts.ckeygen now substitutes a default of "~/.ssh/id_rsa" if no keyfile is specified. (#6607)
• Correct type hints for IHostnameResolver.resolveHostName and IResolverSimple.getHostByName. (#10276)
• twist conch --auth=sshkey can now authenticate users without a traceback again, thanks to twisted.conch.unix.UnixConchUser no longer being incorrectly instantiated with bytes. In the course of this fix, some type hinting has also been applied to twisted.cred.portal. (#11626)
• twisted.internet.gireactor now works with Gtk4, and is tested and supported in CI again. (#11705)
• When interrupted with control-C, trial -j no longer obscures tracebacks for any errors caused by that interruption with an UnboundLocalError due to a bug in its own implementation. Note that there are still several internal tracebacks that will be emitted upon exiting, because tearing down the test runner mid-suite is still not an entirely clean operation, but it should at least be possible to see errors reported from, for example, a test that is hanging more clearly. (#11707)
• PortableGIReactor and PortableGtkReactor are no longer necessary and are now aliases of GIReactor and Gtk2Reactor respectively, improving the performance of any applications using them. (#11738)
• The Twisted package dependencies were updated to minimum versions that will work with latest Twisted codebase. (#11740)
• Deferred's type annotations have been made more comprehensive, precise, correct, and strict. You may notice new type errors in your applications; be sure to check on those because they may represent real type errors! (#11772)
• To prevent parsing errors and ensure validity when serializing HTML comments, twisted.web.template.flattenString has been updated to escape the --> sequence within comments. (#11804)
• BadZipfile (with a small f) has been deprecated since Python 3.2, use BadZipFile (big F) instead, added in 3.2. (#11821)
• twisted.web.template now avoids unnecessary copying and is faster, particularly for templates with deep nesting. (#11834)
• twisted.web.template now avoids some unecessary evaluation of type annotations and is faster. (#11835)

twisted - Twisted 23.8.0rc1

Twisted 23.8.0.rc1 (2023-08-17)

This is the last release with support for Python 3.7.

Features

• reactor.spawnProcess() now uses posix_spawnp when possible, making it much more efficient (#5710)
• Twisted now officially supports Python 3.11. (#10343)
• twisted.internet.defer.Deferred.fromFuture now has a more precise type annotation. (#11753)
• twisted.internet.defer._ConcurrencyPrimitive.__aexit__ now has a more precise type annotation. (#11795)
• twisted.internet.defer.race has been added as a way to get the first available result from a list of Deferreds. (#11817)
• The CI suite was updated to execute the tests using a Python 3.12 pre-release (#11857)

Bugfixes

• twisted.conch.scripts.ckeygen now substitutes a default of "~/.ssh/id_rsa" if no keyfile is specified. (#6607)
• Correct type hints for IHostnameResolver.resolveHostName and IResolverSimple.getHostByName. (#10276)
• twist conch --auth=sshkey can now authenticate users without a traceback again, thanks to twisted.conch.unix.UnixConchUser no longer being incorrectly instantiated with bytes. In the course of this fix, some type hinting has also been applied to twisted.cred.portal. (#11626)
• twisted.internet.gireactor now works with Gtk4, and is tested and supported in CI again. (#11705)
• When interrupted with control-C, trial -j no longer obscures tracebacks for any errors caused by that interruption with an UnboundLocalError due to a bug in its own implementation. Note that there are still several internal tracebacks that will be emitted upon exiting, because tearing down the test runner mid-suite is still not an entirely clean operation, but it should at least be possible to see errors reported from, for example, a test that is hanging more clearly. (#11707)
• PortableGIReactor and PortableGtkReactor are no longer necessary and are now aliases of GIReactor and Gtk2Reactor respectively, improving the performance of any applications using them. (#11738)
• The Twisted package dependencies were updated to minimum versions that will work with latest Twisted codebase. (#11740)
• Deferred's type annotations have been made more comprehensive, precise, correct, and strict. You may notice new type errors in your applications; be sure to check on those because they may represent real type errors! (#11772)
• To prevent parsing errors and ensure validity when serializing HTML comments, twisted.web.template.flattenString has been updated to escape the --> sequence within comments. (#11804)
• BadZipfile (with a small f) has been deprecated since Python 3.2, use BadZipFile (big F) instead, added in 3.2. (#11821)
• twisted.web.template now avoids unnecessary copying and is faster, particularly for templates with deep nesting. (#11834)
• twisted.web.template now avoids some unecessary evaluation of type annotations and is faster. (#11835)
• utcfromtimestamp has been deprecated since Python 3.12, use fromtimestamp(x, timezone.utc).replace(tzinfo=None) instead. (#11908)

Deprecations and Removals

• Optional dependency "extras" names like conch_nacl now use hyphens rather than underscores to comply with PEP 685. The old names will be supported until the end of 2023. (#11655)
• twisted.internet.gtk2reactor, twisted.internet.gtk3reactor, and twisted.internet.glib2reactor are now deprecated in favor of twisted.internet.gireactor. (#11705)

Twisted 22.10.0rc1 release candidate was released on 2022-10-26 and there are no changes between the release candidate and the final release.

Features

• The systemd: endpoint parser now supports "named" file descriptors. This is a more reliable mechanism for choosing among several inherited descriptors. (#8147)

Improved Documentation

• The systemd endpoint parser's index parameter is now documented as leading to non-deterministic results in which descriptor is selected. The new name parameter is now documented as preferred. (#8146)
• The implementers of Zope interfaces are once more displayed in the documentations. (#11690)

Deprecations and Removals

• twisted.protocols.dict, which was deprecated in 17.9, has been removed. (#11725)

• twisted.web.vhost.NameVirtualHost no longer echoes HTML received in the Host header without escaping it (CVE-2022-39348, GHSA-vg46-2rrj-3647). (#11716)

Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~

• twisted.web.resource.Resource.putChild now raises TypeError when the path argument is not bytes, rather than issuing a deprecation warning. (#8985)
• The twisted.web.resource.ErrorPage, NoResource, and ForbiddenResource classes have been deprecated in favor of new implementations twisted.web.pages module because they permit HTML injection. (#11716)

• Type hinting was added to twisted.internet.defer, making this is the first release of Twisted where you might reasonably be able to use mypy without your own custom stub files (#10017)

Bugfixes

• The changes to DelayedCall.__repr__ and LoopingCall.__repr__ from 21.7.0.rc1 were reverted as the wrong assumption that __qualname__ is available on all the supported Python versions. (#10235)
• The automated release process was updated to generate and release wheel files to PyPy (#10236)

.. towncrier release notes start

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.seteventloop_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)
• The "Writing a twistd plugin" howto now explains how to deploy twistd plugins using Python packaging and pip (#9243)
• (#9868, #9873, #9874)
• Fix a typo in "Introduction to Deferreds" document. (#9948)
• The Twisted Coding Standard has been changed to refer to The Black code style for guidelines regarding whitespace and line lengths. (#9957)
• Exempt __repr__, __slots__ and other @attrs.define related changes from compatibility policy. (#9982)
• Fix many docstring mistakes flagged by new sanity checks in pydoctor. (#10021)
• Fix a few dozen broken links to API documentation pages. (#10057)

Deprecations and Removals

• twisted.cred.credentials.UsernameHashedPassword is now deprecated because it doesn't hash the password, causing it to return the wrong result. (#8368)
• twisted.news is now removed from the codebase. (This module was never installed on Python 3.) (#9782)
• Support for Python 2.7 has been removed. Twisted now supports only Python versions 3.5/3.6/3.7. (#9790)
• twisted.pair.ethernet.IEthernetProtocol.addProto()'s interface was changed to match the existing implementations in the Twisted source code. (#9877)
• twisted.python.filepath.FilePath.statinfo was deprecated in Twisted 15.0.0 and has now been removed. (#9881)
• The parameters to twisted.internet.base.ReactorBase.addSystemEventTrigger(), twisted.internet.base.ReactorBase.callWhenRunning(), twisted.internet.base.ReactorBase.callLater(), twisted.internet.task.Clock.callLater() have been renamed to match the parameters defined in the following interfaces: twisted.internet.interfaces.IReactorCore, twisted.internet.interfaces.IReactorTime. (#9897)
• Functions and types in twisted.python.compat that existed to support the transition from Python 2 to 3 have been deprecated. (#9922)
• twisted.logger.LoggingFile.softspace has been deprecated. (#10042)
• twisted.python.win32.WindowsError and FakeWindowsError have been deprecated. (#10053)
• twisted.mail.pop3client has been renamed to twisted.mail._pop3client, since it has always been a private implementation module. (#10054)

Published by rodrigc over 5 years ago

twisted - twisted-21.2.0rc1

Twisted 21.2.0.rc1 (2021-02-14)

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)

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.seteventloop_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)

Improved Documentation

• The narrative docs now contains the associated Twisted version and the date when they were generated. (#3945)
• The "Writing a twistd plugin" howto now explains how to deploy twistd plugins using Python packaging and pip (#9243)
• (#9868, #9873, #9874)
• Fix a typo in "Introduction to Deferreds" document. (#9948)
• The Twisted Coding Standard has been changed to refer to The Black code style for guidelines regarding whitespace and line lengths. (#9957)
• Exempt __repr__, __slots__ and other @attrs.define related changes from compatibility policy. (#9982)
• Fix many docstring mistakes flagged by new sanity checks in pydoctor. (#10021)
• Fix a few dozen broken links to API documentation pages. (#10057)

Deprecations and Removals

• twisted.cred.credentials.UsernameHashedPassword is now deprecated because it doesn't hash the password, causing it to return the wrong result. (#8368)
• twisted.news is now removed from the codebase. (This module was never installed on Python 3.) (#9782)
• Support for Python 2.7 has been removed. Twisted now supports only Python versions 3.5/3.6/3.7. (#9790)
• twisted.pair.ethernet.IEthernetProtocol.addProto()'s interface was changed to match the existing implementations in the Twisted source code. (#9877)
• twisted.python.filepath.FilePath.statinfo was deprecated in Twisted 15.0.0 and has now been removed. (#9881)
• The parameters to twisted.internet.base.ReactorBase.addSystemEventTrigger(), twisted.internet.base.ReactorBase.callWhenRunning(), twisted.internet.base.ReactorBase.callLater(), twisted.internet.task.Clock.callLater() have been renamed to match the parameters defined in the following interfaces: twisted.internet.interfaces.IReactorCore, twisted.internet.interfaces.IReactorTime. (#9897)
• Functions and types in twisted.python.compat that existed to support the transition from Python 2 to 3 have been deprecated. (#9922)
• twisted.logger.LoggingFile.softspace has been deprecated. (#10042)
• twisted.python.win32.WindowsError and FakeWindowsError have been deprecated. (#10053)
• twisted.mail.pop3client has been renamed to twisted.mail._pop3client, since it has always been a private implementation module. (#10054)
