Twisted 20.3.0 (2020-03-13)
===========================
Bugfixes
--------
- twisted.protocols.amp.BoxDispatcher.callRemote and callRemoteString will no longer return failing Deferreds for requiresAnswer=False commands when the transport they're operating on has been disconnected. (#9756)
Improved Documentation
----------------------
- Added a missing hyphen to a reference to the ``--debug`` option of ``pdb`` in the Trial how-to. (#9690)
- The documentation of the twisted.cred.checkers module has been extended and corrected. (#9724)
Deprecations and Removals
-------------------------
- twisted.news is deprecated. (#9405)

Conch
-----
Features
~~~~~~~~
- twisted.conch.ssh now supports the curve25519-sha256 key exchange algorithm (requires OpenSSL >= 1.1.0). (#6814)
- twisted.conch.ssh.keys can now write private keys in the new "openssh-key-v1" format, introduced in OpenSSH 6.5 and made the default in OpenSSH 7.8. ckeygen has a corresponding new --private-key-subtype=v1 option. (#9683)
Bugfixes
~~~~~~~~
- twisted.conch.keys.Key.privateBlob now returns the correct blob format for ECDSA (i.e. the same as that implemented by OpenSSH). (#9682)
Misc
~~~~
- #9760
Web
---
Bugfixes
~~~~~~~~
- Fixed return type of twisted.web.http.Request.getUser and twisted.web.http.Request.getPassword to binary if no authorization header was found or an exception was thrown (#9596)
- twisted.web.http.HTTPChannel now rejects requests (with status code 400 and a drop) that have malformed headers of the form "Foo : value" or ": value". (#9646)
- twisted.web.http.Request now correctly parses multipart-encoded form data submitted as a chunked request on Python 3.7+. (#9678)
- twisted.web.client.BrowserLikePolicyForHTTPS is now listed in __all__, since it's a user-facing class that anyone could import and extend. (#9769)
- twisted.web.http was subject to several request smuggling attacks. Requests with multiple Content-Length headers were allowed (CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu for reporting this) and now fail with a 400; requests with a Content-Length header and a Transfer-Encoding header honored the first header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for reporting this) and now fail with a 400; requests whose Transfer-Encoding header had a value other than "chunked" and "identity" (thanks to ZeddYu Lu) were allowed and now fail with a 400.

Twisted 19.10.0 (2019-11-03)
============================
Features
--------
- twisted.trial.successResultOf, twisted.trial.failureResultOf, and
twisted.trial.assertNoResult accept coroutines as well as Deferreds. (#9006)
Bugfixes

- #9689
Web
---
Features
~~~~~~~~
- twisted.web.server.Request will now use twisted.web.server.Site.getContentFile, if it exists, to get a file into which to write request content. If getContentFile is not provided by the site, it will fall back to the previous behavior of using io.BytesIO for small requests and tempfile.TemporaryFile for large ones. (#9655)
Bugfixes
~~~~~~~~
- twisted.web.client.FileBodyProducer will now stop producing when the Deferred returned by FileBodyProducer.startProducing is cancelled. (#9547)
- The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood). Thanks to Jonathan Looney and Piotr Sikora. (#9694)

~~~~~~~~
- twisted.web.client.HostnameCachingHTTPSPolicy was added as a new contextFactory option. The policy caches a specified number of twisted.internet.interfaces.IOpenSSLClientConnectionCreator instances to to avoid the cost of instantiating a connection creator for multiple requests to the same host. (#9138)
Bugfixes
~~~~~~~~
- twisted.web.http.Request.cookies, twisted.web.http.HTTPChannel.writeHeaders, and twisted.web.http_headers.Headers were all vulnerable to header injection attacks. They now replace linear whitespace ('\r', '\n', and '\r\n') with a single space. twisted.web.http.Reqeuest.cookies also replaces semicolons (';') with a single space. (#9420)

- Python 3.7 is now supported. (#9502)
Bugfixes
--------
- twisted.logger.LogBeginner's default critical observer now prints tracebacks for new and legacy log system events through the use of the new eventAsText API. This API also does not raise an error for non-ascii encoded data in Python2, it attempts as well as possible to format the traceback. (#7927)
- Syntax error under Python 3.7 fixed for twisted.conch.manhole and
twisted.main.imap4. (#9384)
- `trial -j` reports tracebacks on test failures under Python 3. (#9436)

Twisted 18.7.0 (2018-07-10)
===========================
Features
--------
- Cancelling a Deferred returned by twisted.internet.defer.inlineCallbacks now cancels the Deferred it is waiting on. (#4632)
- twisted.application.internet.ClientService now accepts a function to initialize or validate a connection before it is returned by the whenConnected method as the prepareConnection argument. (#8375)
- Traceback generated for twisted.internet.defer.inlineCallbacks now includes the full stack of inlineCallbacks generators between catcher and raiser (before it only contained raiser's stack). (#9176)
- Add optional cwd argument to twisted.runner.procmon.ProcMon.addProcess (#9287)
- twisted.python.failure.Failure tracebacks generated by coroutines scheduled with twisted.internet.defer.ensureDeferred - i.e. any Deferred-awaiting coroutine - now contain fewer extraneous frames from the trampoline implementation, and correctly indicate the source of exceptions raised in other call stacks - i.e. the function that raised the exception. In other words: if you 'await' a function that raises an exception, you'll be able to see where the error came from. (#9459)
Bugfixes
--------
- On UNIX-like platforms, Twisted attempts to recover from EMFILE when accepting connections on TCP and UNIX ports by shedding incoming clients. (#5368)
- The documentation of IReactorTime.getDelayedCalls() has been corrected to indicate that the method returns a list, not a tuple. (#9418)
- "python -m twisted web --help" now refers to "--listen" instead of the non-existing "--http" (#9434)
- twisted.python.htmlizer.TokenPrinter now explicitly works on bytestrings. (#9442)
- twisted.enterprise.adbapi.ConnectionPool.runWithConnection and runInteraction now use the reactor that is passed to ConnectionPool's constructor. (#9467)
Improved Documentation
----------------------
- The Twisted Coding Standard now contains examples of how to mark up a feature as added in the next Twisted release. (#9460)
Deprecations and Removals
-------------------------
- Deprecate direct introspection of ProcMon's processes: processes should not be directly accessed or pickled. (#9287)
- twisted.internet.address.IPv4Address._bwHack and twisted.internet.address.UNIXAddress._bwHack, as well as the parameters to the constructors, deprecated since Twisted 11.0, have been removed. (#9450)

Conch
-----
Features
~~~~~~~~
- twisted.conch.ssh.transport.SSHTransportBase now includes Twisted's version in the software version string it sends to the server, allowing servers to apply compatibility workarounds for bugs in particular client versions. (#9424)
Bugfixes
~~~~~~~~
- If the command run by twisted.conch.endpoints.SSHCommandClientEndpoint exits because of a delivered signal, the client protocol's connectionLost is now called with a ProcessTerminated exception instead of a ConnectionDone exception. (#9412)
- twisted.conch.ssh.transport.SSHTransportBase now correctly handles MSG_DEBUG with a false alwaysDisplay field on Python 2 (broken since 8.0.0). (#9422)
- twisted.conch.manhole.lastColorizedLine now does not throw a UnicodeDecodeError on non-ASCII input. (#9442)
Web
---
Features
~~~~~~~~
- Added support for SameSite cookies in ``http.Request.addCookie``. (#9387)
Bugfixes
~~~~~~~~
- twisted.web.server.GzipEncoderFactory would sometimes fail to gzip requests if the Accept-Encoding header contained whitespace between the comma-separated acceptable encodings. It now trims whitespace before checking if gzip is an acceptable encoding. (#9086)
- twisted.web.static.File renders directory listings on Python 2, including those with text paths. (#9438)
- twisted.python.http.Request now correcly parses multipart bodies on Python 3.7. (#9448)
- twisted.web.http.combinedLogFormatter (used by t.w.http.Server and t.w.server.Site) no longer produces DeprecationWarning about Request.getClientIP. (#9470)

Twisted 18.4.0 (2018-04-13)
===========================
Features
--------
- The --port/--https arguments to web plugin are now deprecated, in favor of
--listen. The --listen argument can be given multiple times to listen on
multiple ports. (#6670)
- Twisted now requires zope.interface 4.4.2 or higher across all platforms and
Python versions. (#8149)
- The osx_platform setuptools extra has been renamed to macos_platform, with
the former name being a compatibility alias. (#8848)
- Zsh completions are now provided for the twist command. (#9338)
- twisted.internet.endpoints.HostnameEndpoint now has a __repr__ method which
includes the host and port to which the endpoint connects. (#9341)
Bugfixes
--------
- twistd now uses the UID's default GID to initialize groups when --uid is
given but --gid is not. This prevents an unhandled TypeError from being
raised when os.initgroups() is called. (#4442)
- twisted.protocols.basic.LineReceiver checks received lines' lengths against
its MAX_LENGTH only after receiving a complete delimiter. A line ending in a
multi-byte delimiter like '\r\n' might be split by the network, with the
first part arriving before the rest; previously, LineReceiver erroneously
disconnected if the first part, e.g. 'zzzz....\r' exceeded MAX_LENGTH.
LineReceiver now checks received data against MAX_LENGTH plus the delimiter's
length, allowing short reads to complete a line. (#6556)
- twisted.protocols.basic.LineOnlyReceiver disconnects the transport after
receiving a line that exceeds MAX_LENGTH, like LineReceiver. (#6557)
- twisted.web.http.Request.getClientIP now returns the host part of the
client's address when connected over IPv6. (#7704)
- twisted.application.service.IService is now documented as requiring the
'running', 'name' and 'parent' attributes (the documentation previously
implied they were required, but was unclear). (#7922)
- twisted.web.wsgi.WSGIResource no longer raises an exception when a client
connects over IPv6. (#8241)
- When using TLS enable automatic ECDH curve selection on OpenSSL 1.0.2+
instead of only supporting P-256 (#9210)
- twisted.trial._dist.worker and twisted.trial._dist.workertrial consistently
pass bytes, not unicode to AMP. This fixes "trial -j" on Python 3. (#9264)
- twisted.trial.runner now uses the 'importlib' module instead of the 'imp'
module on Python 3+. This eliminates DeprecationWarnings caused by importing
'imp' on Python 3. (#9275)
- twisted.web.client.HTTP11ClientProtocol now closes the connection when the
server is sending a header line which is longer than he line limit of
twisted.protocols.basic.LineReceiver.MAX_LENGTH. (#9295)
- twisted.python.failure now handles long stacktraces better; in particular it
will log tracebacks for stack overflow errors. (#9301)
- The "--_shell-completion" argument to twistd now works on Python 3. (#9303)
- twisted.python.failure.Failure now raises the wrapped exception in Python3,
and self (Failure) n Python2 when trap() is called without a matching
exception (#9307)
- Writing large amounts of data no longer implies repeated, expensive copying
under Python 3. Python 3's write speeds are now as fast as Python 2's.
(#9324)
- twisted.protocols.postfix now properly encodes errors which are unicode
strings to bytes. (#9335)
- twisted.protocols.policies.ProtocolWrapper and
twisted.protocols.tls.TLSMemoryBIOProtocol no longer create circular
references that keep protocol instances in memory after connection is closed.
(#9374)
- twisted.conch.ssh.transport.SSHTransportBase no longer strips trailing spaces
from the SSH version string of the connected peer. (#9377)
- `trial -j` no longer crashes on Python 2 on test failure messages containing
non-ASCII bytes. (#9378)
- RSA keys replaced with 2048bit ones in twisted.conch.test.keydata in order to
be compatible with OpenSSH 7.6. (#9388)
- AsyncioSelectorReactor uses the global policy's event loop. asyncio libraries
that retrieve the running event loop with get_event_loop() will now receive
the one used by AsyncioSelectorReactor. (#9390)
Improved Documentation
----------------------
- public attributes of `twisted.logger.Logger` are now documented as
attributes. (#8157)
- List indentation formatting errors have been corrected throughout the
documentation. (#9256)
Deprecations and Removals
-------------------------
- twisted.protocols.basic.LineOnlyReceiver.lineLengthExceeded no longer returns
twisted.internet.error.ConnectionLost. It instead directly disconnects the
transport and returns None. (#6557)
- twisted.python.win32.getProgramsMenuPath and
twisted.python.win32.getProgramFilesPath were deprecated in Twisted 15.3.0
and have now been removed. (#9312)
- Python 3.3 is no longer supported. (#9352)

Bugfixes
~~~~~~~~
- twisted.plugins.cred_unix now properly converts a username and password from
bytes to str on Python 3. In addition, passwords which are encrypted with
SHA512 and SH256 are properly verified. This fixes running a conch server
with: "twistd -n conch -d /etc/ssh/ --auth=unix". (#9130)
- In twisted.conch.scripts.conch, on Python 3 do not write bytes directly to
sys.stderr. On Python 3, this fixes remote SSH execution of a command which
fails. (#9344)
Deprecations and Removals
~~~~~~~~~~~~~~~~~~~~~~~~~
- twisted.conch.ssh.filetransfer.FileTransferClient.wasAFile attribute has been
removed as it serves no purpose. (#9362)
- Removed deprecated support for PyCrypto key objects in conch (#9368)
Web
---
Features
~~~~~~~~
- The new twisted.iweb.IRequest.getClientAddress returns the IAddress provider
representing the client's address. Callers should check the type of the
returned value before using it. (#7707)
- Eliminate use of twisted.python.log in twisted.web modules. (#9280)
Bugfixes
~~~~~~~~

Twisted 17.9.0 (2017-09-23)
===========================
This is the last Twisted release where Python 3.3 is supported, on any
platform.
Features
--------
- twisted.python.failure.Failure is now a new-style class which subclasses
BaseException. (#5519)
- twisted.internet.posixbase.PosixReactorBase.adoptStreamPort and
twisted.internet.posixbase.PosixReactorBase.adoptStreamConnection now support
AF_UNIX SOCK_STREAM sockets. (#5573)
- (#8940)
- t.protocol.policies.TimeoutMixin.setTimeout and
t.protocol.policies.TimeoutProtocol.cancelTimeout (used in
t.protocol.policies.TimeoutFactory) no longer raise a
t.internet.error.AlreadyCancelled exception when calling them for an already
cancelled timeout. (#9131)
- twisted.web.template.flatten now supports coroutines that yield Deferreds.
(#9199)
- twisted.web.client.HTTPConnectionPool passes the repr() of the endpoint to
the client protocol factory, and the protocol factory adds that to its own
repr(). This makes logs more useful. (#9235)
- Python 3.6 is now supported (#9240)
Bugfixes
--------
- twisted.python.logfile.BaseLogFile and subclasses now always open the file in
binary mode, and will process text as UTF-8. (#6938)
- The `ssl:` endpoint now accepts `certKey` PEM files without trailing
newlines. (#7530)
- Logger.__init__ sets the namespace to "<unknown>" instead of raising KeyError
when unable to determine the namespace from the calling context. (#7930)
- twisted.internet._win32serialport updated to support pySerial 3.x and dropped
pySerial 2.x support. (#8159)
- twisted.python.rebuild now works on Python 3. (#8213)
- twisted.web.server.Request.notifyFinish will now once again promptly notify
applications of client disconnection (assuming that the client doesn't send a
large amount of pipelined request data) rather than waiting for the timeout;
this fixes a bug introduced in Twisted 16.3.0. (#8692)
- twisted.web.guard.HTTPAuthSessionWrapper configured with
DigestCredentialFactory now works on both Python 2 and 3. (#9127)
- Detect when we’re being run using “-m twisted” or “-m twisted.trial” and use
it to build an accurate usage message. (#9133)
- twisted.protocols.tls.TLSMemoryBIOProtocol now allows unregisterProducer to
be called when no producer is registered, bringing it in line with other
transports. (#9156)
- twisted.web web servers no longer print tracebacks when they timeout clients
that do not respond to TLS CLOSE_NOTIFY messages. (#9157)
- twisted.mail.imap4 now works on Python 3. (#9161)
- twisted.python.shortcut now works on Python 3 in Windows. (#9170)
- Fix traceback forwarding with inlineCallbacks on python 3. (#9175)
- twisted.mail.imap4.MessageSet now treats * as larger than every message ID,
leading to more consistent and robust behavior. (#9177)
- The following plugins can now be used on Python 3 with twistd: dns, inetd,
portforward, procmon, socks, and words. (#9184)
- twisted.internet._win32serialport now uses serial.serialutil.to_bytes() to
provide bytes in Python 3. (#9186)
- twisted.internet.reactor.spawnProcess() now does not fail on Python 3 in
Windows if passed a bytes-encoded path argument. (#9200)
- twisted.protocols.ident now works on Python 3. (#9221)
- Ignore PyPy's implementation differences in base object class. (#9225)
- twisted.python.test.test_setup now passes with setuptools 36.2.1 (#9231)
- twisted.internet._win32serialport SerialPort._clearCommError() no longer
raises AttributeError (#9252)
- twisted.trial.unittest.SynchronousTestCase and
twisted.trial.unittest.TestCase now always run their tearDown methods, even
when a test method fails with an exception. They also flush all errors logged
by a test method before running another, ensuring the logged errors are
associated with their originating test method. (#9267)
Improved Documentation
----------------------
- Trial's documentation now directly mentions the preferred way of running
Trial, via "python -m twisted.trial". (#9052)
- twisted.internet.endpoints.HostnameEndpoint and
twisted.internet.endpoints.TCP4Client endpoint documentation updated to
correctly reflect that the timeout argument takes a float as well as an int.
(#9151)
- Badges at top of README now correctly render as links to respective result
pages on GitHub. (#9216)
- The example code for the trial tutorial is now compatible with Python3 and
the current version of Twisted. (#9223)
Deprecations and Removals
-------------------------
- twisted.protocols.dict is deprecated. (#9141)
- gpsfix.py has been removed from the examples. It uses twisted.protocols.gps
which was removed in Twisted 16.5.0. (#9253)
- oscardemo.py, which illustrates the use of twisted.words.protocols.oscar, as
been removed. twisted.words.protocols.oscar was removed in Twisted 17.5.0.

to be compatible with Python 3. This lets the conch cli work with Python 3.
(#9265)
Deprecations and Removals

Web
---
Features
~~~~~~~~
- twisted.web.static.File.contentTypes is now documented. (#5739)
- twisted.web.server.Request and any Twisted web server using it now support
automatic fast responses to HTTP/1.1 and HTTP/2 OPTIONS * requests, and
reject any other verb using the * URL form. (#9190)
- --add-header "HeaderName: Value" can be passed to twist web in order to set
extra headers on all responses (#9241)
Bugfixes
~~~~~~~~
- twisted.web.client.HTTPClientFactory(...).gotHeaders(...) now handles a wrong
Set-Cookie header without a traceback. (#9136)
- twisted.python.web.http.HTTPFactory now always opens logFile in binary mode
and writes access logs in UTF-8, to avoid encoding issues and newline
differences on Windows. (#9143)
- The code examples in "Using the Twisted Web Client" now work on Python 3.
(#9172)
- twisted.web.server.Request and all web servers that use it now no longer send
a default Content-Type header on responses that do not have a body (i.e. that
set Content-Length: 0 or that send a 204 status code). (#9191)
- twisted.web.http.Request and all subclasses now correctly fire Deferreds
returned from notifyFinish with errbacks when errors are encountered in
HTTP/2 streams. (#9208)
- twisted.web.microdom, twisted.web.domhelpers, and twisted.web.sux now work on
Python 3. (#9222)
Mail
----
Bugfixes
~~~~~~~~
- Sending a list of recipients with twisted.smtp.SenderFactory has been fixed.
This fixes a problem found when running buildbot. (#9180)

Twisted 17.5.0 (2017-06-04)
===========================
Bugfixes
--------
- spawnProcess no longer opens an unwanted console on Windows (#5726)
- The transition to the hyperlink package adds IPv6 support to
twisted.python.url.URL. This is now deprecated and new code should use
hyperlink directly (see #9126). (#8069)
- twisted.logger now buffers only 200 events by default (reduced from 65536)
while waiting for observers to be configured. (#8164)
- The transition of twisted.python.url to using the hyperlink package enables a
URL.click() with no arguments (or 0-length string argument) to resolve dot
segments in the path. (#8184)
- twisted.protocols.finger now works on Python 3. (#8230)
- TLS-related tests now pass when run with OpenSSL 1.1.0. This makes tests pass
again on macOS and Windows, as cryptography 1.8 and later include OpenSSL
1.1.0. (#8898)
- UNIX socket endpoints now process all messages from recvmsg's ancillary data
via twisted.internet.unix.Server.doRead/twisted.internet.unix.Client.doRead,
while discarding and logging ones that don't contain file descriptors.
(#8912)
- twisted.internet.endpoints.HostnameEndpoint and twisted.web.client.Agent work
again with reactors that do not provide IReactorPluggableNameResolver. This
undoes the changes that broke downstream users such as treq.testing. Note
that passing reactors that do not provide IReactorPluggableNameResolver to
either is deprecated. (#9032)
- A Python 3 Perspective Broker server which receives a remote call with
keyword arguments from a Python 2 client will now decode any keys which are
binary to strings instead of crashing. This fixes interoperability between
Python 2 Buildbot clients and Python 3 Buildbot servers. (#9047)
- twisted.internet._threadedselect now works on both Python 2 and 3. (#9053)
- twisted.internet.interfaces.IResolverSimple implementers will now always be
passed bytes, properly IDNA encoded if required, on Python 2. On Python 3,
they will now be passed correctly IDNA-encoded Unicode forms of the domain,
taking advantage of the idna library from PyPI if possible. This is to avoid
Python's standard library (which has an out of date idna module) from mis-
encoding domain names when non-ASCII Unicode is passed to it. (#9137)
Improved Documentation
----------------------
- The examples in Twisted howto "Using the Twisted Application Framework",
section "Customizing twistd logging" have been updated to use latest logging
modules and syntax (#9084)
Features
--------
- twisted.internet.defer.Deferred.asFuture and
twisted.internet.defer.Deferred.fromFuture were added, allowing for easy
transitions between asyncio coroutines (which await Futures) and twisted
coroutines (which await Deferreds). (#8748)
- twisted.application.internet.ClientService.whenConnected now accepts an
argument "failAfterFailures". If you set this to 1, the Deferred returned by
whenConnected will errback when the connection attempt fails, rather than
retrying forever. This lets you react (probably by stopping the
ClientService) to connection errors that are likely to be persistent, such as
using the wrong hostname, or not being connected to the internet at all.
(#9116)
- twisted.protocols.tls.TLSMemoryBIOProtocol and anything that uses it
indirectly including the TLS client and server endpoints now enables TLS 1.3
cipher suites. (#9128)

Deprecations and Removals
-------------------------
- twisted.runner.inetdconf.InvalidRPCServicesConfError,
twisted.runner.inetdconf.RPCServicesConf, twisted.runner.inetdtap.RPCServer,
and twisted.runner.portmap, deprecated since 16.2.0, have been removed.
(#8464)
- twisted.python.url and twisted.python._url were modified to rely on
hyperlink, a new package based on the Twisted URL implementation. Hyperlink
adds support for IPv6 (fixing #8069), correct username/password encoding,
better scheme/netloc inference, improved URL.click() behavior (fixing #8184),
and more. For full docs see hyperlink.readthedocs.io and the CHANGELOG in the
hyperlink GitHub repo. (#9126)
Conch
-----
Bugfixes
~~~~~~~~
- History-aware terminal protocols like twisted.conch.manhole.Manhole no longer
raise a TypeError when a user visits a partial line they added to the command
line history by pressing up arrow before return. (#9031)
- The telnet_echo.tac example had conflicting port callouts between runtime and
documentation. File was altered to run on documented port, 6023. (#9055)
Deprecations and Removals
~~~~~~~~~~~~~~~~~~~~~~~~~
- Remove diffie-hellman-group1-sha1 from twisted.conch. See https://weakdh.org/
(#9019)
- Removed small and obscure elliptic curves from conch. The only curves conch
supports now are the ones also supported by OpenSSH. (#9088)

---
Bugfixes
~~~~~~~~
- twisted.web.cgi now works on Python 3 (#8009)
- twisted.web.distrib now works on Python 3 (#8010)
- twisted.web.http.HTTPFactory now propagates its reactor's callLater method to
the HTTPChannel object, rather than having callLater grab the global reactor.
This prevents the possibility of HTTPFactory logging using one reactor, but
HTTPChannel running timeouts on another. (#8904)
Improved Documentation
~~~~~~~~~~~~~~~~~~~~~~
- twisted.web.template.flattenString docstring now correctly references
io.BytesIO (rather than NativeStringIO). (#9028)
Features
~~~~~~~~
- twisted.web.client now exposes the RequestGenerationFailed exception type.
(#5310)
- twisted.web.client.Agent will now parse responses that begin with a status
line that is missing a phrase. (#7673)
- twisted.web.http.HTTPChannel and twisted.web._http2.H2Connection have been
enhanced so that after they time out they wait a small amount of time to
allow the connection to close gracefully and, if it does not, they forcibly
close it to avoid allowing malicious clients to forcibly keep the connection
open. (#8902)

Twisted Core 17.1.0 (2017-02-04)
================================
Features
--------
- Added a new interface,
twisted.internet.interfaces.IHostnameResolver, which is an
improvement to twisted.internet.interfaces.IResolverSimple that
supports resolving multiple addresses as well as resolving IPv6
addresses. This is a native, asynchronous, Twisted analogue to
getaddrinfo. (#4362)
- twisted.web.client.Agent now uses HostnameEndpoint internally; as a
consequence, it now supports IPv6, as well as making connections
faster and more reliably to hosts that have more than one DNS name.
(#6712)
- twisted.internet.ssl.CertificateOptions now has the new constructor
argument 'raiseMinimumTo', allowing you to increase the minimum TLS
version to this version or Twisted's default, whichever is higher.
The additional new constructor arguments 'lowerMaximumSecurityTo'
and 'insecurelyLowerMinimumTo' allow finer grained control over
negotiated versions that don't honour Twisted's defaults, for
working around broken peers, at the cost of reducing the security
of the TLS it will negotiate. (#6800)
- twisted.internet.ssl.CertificateOptions now sets the OpenSSL
context's mode to MODE_RELEASE_BUFFERS, which will free the
read/write buffers on idle TLS connections to save memory. (#8247)
- trial --help-reactors will only list reactors which can be
imported. (#8745)
- twisted.internet.endpoints.HostnameEndpoint now uses the passed
reactor's implementation of
twisted.internet.interfaces.IReactorPluggableResolver to resolve
hostnames rather than its own deferToThread/getaddrinfo wrapper;
this makes its hostname resolution pluggable via a public API.
(#8922)
- twisted.internet.reactor.spawnProcess now does not emit a
deprecation warning on Unicode arguments. It will encode Unicode
arguments down to bytes using the filesystem encoding on UNIX and
Python 2 on Windows, and pass Unicode through unchanged on Python 3
on Windows. (#8941)
- twisted.trial._dist.test.test_distreporter now works on Python 3.
(#8943)
Bugfixes
--------
- trial --help-reactors will now display iocp and win32er reactors
with Python 3. (#8745)
- twisted.logger._flatten.flattenEvent now handles log_format being
None instead of assuming the value is always a string. (#8860)
- twisted.protocol.ftp is now Python 3 compatible (#8865)
- twisted.names.client.Resolver can now resolve names with IPv6 DNS
servers. (#8877)
- twisted.application.internet.ClientService now waits for existing
connections to disconnect before trying to connect again when
restarting. (#8899)
- twisted.internet.unix.Server.doRead and
twisted.internet.unix.Client.doRead no longer fail if recvmsg's
ancillary data contains more than one file descriptor. (#8911)
- twist on Python 3 now correctly prints the help text when given no
plugin to run. (#8918)
- twisted.python.sendmsg.sendmsg no longer segfaults on Linux +
Python 2. (#8969)
- IHandshakeListener providers connected via SSL4ClientEndpoint will
now have their handshakeCompleted methods called. (#8973)
- The twist script now respects the --reactor option. (#8983)
- Fix crash when using SynchronousTestCase with Warning object which
does not store a string as its first argument (like
libmysqlclient). (#9005)
- twisted.python.compat.execfile() does not open files with the
deprecated 'U' flag on Python 3. (#9012)
Deprecations and Removals
-------------------------
- twisted.internet.ssl.CertificateOption's 'method' constructor
argument is now deprecated, in favour of the new 'raiseMinimumTo',
'lowerMaximumSecurityTo', and 'insecurelyLowerMinimumTo' arguments.
(#6800)
- twisted.protocols.telnet (not to be confused with the supported
twisted.conch.telnet), deprecated since Twisted 2.5, has been
removed. (#8925)
- twisted.application.strports.parse, as well as the deprecated
default arguments in strports.service/listen, deprecated since
Twisted 10.2, has been removed. (#8926)
- twisted.web.client.getPage and twisted.web.client.downloadPage have
been deprecated in favour of https://pypi.org/project/treq and
twisted.web.client.Agent. (#8960)
- twisted.internet.defer.timeout is deprecated in favor of
twisted.internet.defer.Deferred.addTimeout (#8971)

Bugfixes
--------
- twisted.web.http.HTTPFactory now times connections out after one
minute of no data from the client being received, before the
request is complete, rather than twelve hours. (#3746)
- twisted.web.http.HTTPChannel, the server class for Twisted's
HTTP/1.1 server, now exerts backpressure against clients that do
not read responses. This means that if a client stops reading from
a socket for long enough, Twisted will stop reading further
requests from that client until it consumes some responses. (#8868)
- twisted.web.http_headers.Headers.getRawHeaders no longer attempts
to decode the default value when called with a unicode header name.
(#8974)
- twisted.web.http.HTTPChannel is less likely to leak file
descriptors when timing out clients using HTTPS connections. In
some cases it is still possible to leak a file descriptor when
timing out HTTP clients: further patches will address this issue.

the generator is wrapped with
twisted.internet.defer.ensureDeferred. (#8087)
- twisted.internet.asyncioreactor has been added, which is a Twisted
reactor on top of Python 3.4+'s native asyncio reactor. It can be
selected by passing "--reactor=asyncio" to Twisted tools (twistd,
Trial, etc) on platforms that support it (Python 3.4+). (#8367)
- twisted.python.zippath now works on Windows with Python 3. (#8747)
- twisted.internet.cfreactor is ported to Python 3 and supported on
2.7 and 3.5+. (#8838)
Bugfixes
--------
- twisted.internet.test.test_iocp and twisted.internet.test.test_tcp
have been fixed to work under Python 3 with the Windows IOCP
reactor (#8631)
- Arguments to processes on Windows are now passed mbcs-encoded
arguments. This prevents process-related tests from hanging on
Windows with Python 3. (#8735)
- Client and server TLS connections made via the client TLS endpoint
and the server SSL endpoint, as well as any other code that uses
twisted.internet.ssl.CertificateOptions, no longer accept 3DES-
based cipher suites by default, to defend against SWEET32. (#8781)
- twisted.logger.jsonFileLogObserver no longer emits non-JSON
tracebacks into its file; additionally,
twisted.logger.formatEventAsClassicLogText now includes traceback
information for the log event it formats. (#8858)
- twisted.python.version now exports a version of Incremental that is
16.10.1 or higher, making t.p.v.Version package name comparisons
case-insensitive. (#8863)
- twisted.python.reflect.safe_str encodes unicode as ascii with
backslashreplace error handling on Python 2. (#8864)
Improved Documentation
----------------------
- The twisted.internet.interfaces.IProtocol.dataReceived() method
takes one parameter of type bytes. This has been clarified in the
doc string. (#8763)
Deprecations and Removals
-------------------------
- twisted.python.constants is deprecated in preference to constantly
on PyPI, which is the same code rolled into its own package.
(#7351)
- twisted.python.dist3 has been made private API. (#8761)
- When the source code is checked out, bin/trial is no longer in the
tree. Developers working on the Twisted source code itself should
either (1) run all tests under tox, or (2) run 'python setup.py
develop' to install trial before running any tests. (#8765)
- twisted.protocols.gps, deprecated since Twisted 15.2, has been
removed. (#8787)

Bugfixes
--------
- twisted.web.client.HTTPConnectionPool and anything that uses it,
like twisted.web.client.Agent, have had their logic for resuming
transports changed so that transports are resumed after state
machine transitions are complete, rather than before. This change
allows the HTTP client infrastructure to work with alternative HTTP
implementations such as HTTP/2 which may be able to deliver a
complete response synchronously when producing is resumed. (#8720)

Twisted Core 16.4.0 (2016-08-25)
================================
Features
--------
- Add twisted.application.twist, meant to eventually replace twistd
with a simpler interface. Add twisted.application.runner API,
currently private, which twist is built on. (#5705)
- The new interface IHandshakeListener that can be implemented by any
Protocol provides a callback that is called when the TLS handshake
has been completed, allowing Protocols to make decisions about the
TLS configuration before application data is sent. (#6024)
- twisted.python.syslog has been ported to Python 3. (#7957)
- twisted.internet.defer.ensureDeferred has been added, similar to
asyncio's ensure_future. Wrapping a coroutine (the result of a
function defined using async def, available only on Python 3.5+)
with it allows you to use the "await" keyword with Deferreds inside
the coroutine, similar to "yield" when using inlineCallbacks.
(#8088)
- twisted.internet.inotify have been ported to Python 3 (#8211)
- twisted.enterprise has been ported to Python 3. The third-party
pysqlite2 package has not been ported to Python 3, so any database
connector based on pysqlite2 cannot be used. Instead the sqlite3
module included with Python 3 should be used. (#8303)
- Scripts such as cftp, ckeygen, conch, mailmail, pyhtmlizer,
tkconch, twistd and trial have been updated to be setuptools
console scripts. (#8491)
- twisted.pair.raw and twisted.pair.rawudp have been ported to Python
3 (#8545)
- twisted.internet.baseprocess has been ported to Python 3. (#8546)
- twisted.python.dist has been ported to Python 3 (#8556)
- twisted.internet.interfaces.IOpenSSLContextFactory has been added,
which defines the interface provided both by the old-style
twisted.internet.ssl.ContextFactory class and the newer
twisted.interface.ssl.CertificateOptions class. This is a precursor
to formally deprecating the former class in favour of the latter.
(#8597)
- twisted.python.zipstream has been ported to Python 3 (#8607)
- Zip file entries returned by ChunkingZipFile.readfile() are now
context managers. (#8641)
- twisted.protocols.socks has been ported to Python 3 (#8665)
- twisted.spread.banana has been ported to Python 3 (#8667)
- Trial can now be invoked via "python -m twisted.trial". (#8712)
- twisted.protocols.postfix has been ported to Python 3 (#8713)
- twisted.protocols.wire and twisted.protocols.portforwarding have
been ported to Python 3 (#8717)
- twisted.protocols.stateful has been ported to Python 3 (#8718)
- twisted.protocols.memcache is now compatible with Python 3. (#8726)
- twisted.protocols.dict has been ported to Python 3 (#8732)
Bugfixes
--------
- pip install -e ".[dev]" now works on Python 3, but it will not
install twistedchecker or pydoctor, which have not yet been ported.
(#7807)
- twistd can now properly daemonize on Linux/Unix when run under
Python3 and will not hang indefinitely. (#8155)
- tox can now be used to run Twisted's tests on Windows (#8578)
- twisted.python.filepath.setContent() and
twisted.python.filepath.moveTo() now work on Windows with Python 3
(#8610)
- twisted.internet.win32eventreactor works on Python 3 in Windows
(#8626)
- The TLS payload buffer size was reduced in
twisted.protocols.tls.TLSMemoryBIOProtocol. This fixes writing of
very long strings using the TLSv1_1 method from the OpenSSL
library. (#8693)
- twisted.logger._flatten.flattenEvent() now does not crash if passed
a unicode string. (#8699)
- twisted.application.strports.service (and thus twistd) no longer
swallow asynchronous exceptions from IStreamServerEndpoint.listen.
(#8710)
- _twistd_unix now reports the name and encoded message of an
exception raised during daemonization on Python 2 and 3. (#8731)
- twisted.protocols.amp now handles floats on Python 3. Previously,
sending a float would raise a ValueError. (#8746)
Improved Documentation
----------------------
- Some broken links to xprogramming in the unit test documentation
have been fixed. (#8579)
- The Twisted Tutorial "The Evolution of Finger" has been updated to
use endpoints throughout. (#8588)
- Updated the mail examples to use endpoints and better TLS. (#8595)
- Changed the Twisted Web howto to use endpoints and modern TLS.
(#8596)
- Updated bug report URL in man pages. (#8600)
- In twisted.internet.udp.Port, write() takes a parameter of type
bytes. This is clarified in the docstring. (#8635)
- twisted.internet.interfaces.ITransport.write() and
twisted.internet.interfaces.ITransport.writeSequence() take bytes
parameters. (#8636)
- twisted.python.filepath.AbstractFilePath.getContent() returns
bytes. The docstring was updated to clarify this. (#8637)
- Updated release notes to reflect that 15.4 is the last version that
supported Python 2.6, not 15.5. (#8651)
- A missing space in defer.rst resulted in badly rendered output. The
space was added. (#8723)
Deprecations and Removals

===============================
Features
--------
- Twisted web HTTP/2 servers now time out HTTP/2 connections in the
same manner as HTTP/1.1 connections. (#8480)
Bugfixes
--------
- A bug in twisted.web.server.Site.makeSession which may lead to
predictable session IDs was fixed. Session IDs are now generated
securely using `os.urandom`. (#3460)
- twisted.web.server.Request.getSession will now, for a request sent
over HTTPS, set a "Secure" cookie, preventing the secure session
from being sent over plain-text HTTP. (#3461)
- If called multiple times, twisted.web.http.Request.setLastModified
now correctly observes the greatest supplied value. (#3807)
- The HTTP server now correctly times connections out. (broken in
16.2) (#8481)
- Twisted's HTTP/2 support no longer throws priority exceptions when
WINDOW_UDPATE frames are received after a response has been
completed. (#8558)
- twisted.web.twcgi.CGIScript will now not pass the "Proxy" header to
CGI scripts, as a mitigation to CVE-2016-1000111. (#8623)
- Twisted Web's HTTP/2 server can now tolerate streams being reset by
the client midway through a data upload without throwing
exceptions. (#8682)
- twisted.web.http.Request now swallows header writes on reset HTTP/2
streams, rather than erroring out. (#8685)
- twisted.web's HTTP/2 server now tolerates receiving WINDOW_UPDATE
frames for streams for which it has no outstanding data to send.
(#8695)
- twisted.web.http.HTTPChannel now resumes producing on finished,
non-persistent connections. This prevents HTTP/1 servers using TLS
from leaking a CLOSE_WAIT socket per request. (#8766)

Twisted Runner 16.3.0 (2016-07-05)
==================================
No significant changes have been made for this release.
Twisted Web 16.3.0 (2016-07-05)
===============================
Features
--------
- twisted.web.http.HTTPChannel now implements ITransport. Along with
this change, twisted.web.http.Request now directs all its writes to
the HTTPChannel, rather than to the backing transport. This change
is required for future HTTP/2 work. (#8191)
- twisted.web.http.HTTPChannel now has a HTTP/2 implementation which
will be used if the transport has negotiated using it through
ALPN/NPN (see #8188). (#8194)
Bugfixes
--------
- twisted.web.client.Agent and twisted.web.client.ProxyAgent now add
brackets to IPv6 literal addresses in the host header they send.
(#8369)
- The HTTP server now correctly times connections out. (broken in
16.2) (#8481)
Deprecations and Removals
-------------------------
- twisted.web would previously dispatch pipelined requests
simultaneously and queue the responses. This behaviour did not
enforce any of the guarantees required by RFC 7230 or make it
possible for users to enforce those requirements. For this reason,
the parallel dispatch of requests has been removed. Pipelined
requests are now processed serially. (#8320)
Twisted Words 16.3.0 (2016-07-05)
=================================
No significant changes have been made for this release.
Twisted Core 16.2.0 (2016-05-18)
================================
Features
--------
- twisted.protocols.haproxy.proxyEndpoint provides an endpoint that
wraps any other stream server endpoint with the PROXY protocol that
retains information about the original client connection handled by
the proxy; this wrapper is also exposed via the string description
prefix 'haproxy'; for example 'twistd web --port haproxy:tcp:8765'.
(#8203)
- twisted.application.app.AppLogger (used by twistd) now uses the new
logging system. (#8235)
Bugfixes
--------
- twisted.application-using applications (trial, twistd, etc) now
work with the --reactor option on Python 3. (#8299)
- Failures are now logged by STDLibLogObserver. (#8316)
Improved Documentation
----------------------
- Deprecation documentation was extended to include a quick check
list for developers. (#5645)
- The Twisted Deprecation Policy is now documented in the Twisted
Development Policy. (#8082)
- The documentation examples for UDP now work on Python 3. (#8280)
Deprecations and Removals
-------------------------
- Passing a factory that produces log observers that do not implement
twisted.logger.ILogObserver or twisted.python.log.ILogObserver to
twisted.application.app.AppLogger has been deprecated. This is
primarily used by twistd's --logger option. Please use factories
that produce log observers implementing twisted.logger.ILogObserver
or the legacy twisted.python.log.ILogObserver. (#8235)
- twisted.internet.qtreactor, a stub that imported the external
qtreactor, has been removed. (#8288)

===============================
Features
--------

argument, for explicit reactor selection. (#8246)
Bugfixes
--------
- twisted.web.http.HTTPChannel.headerReceived now respond with 400
and disconnect when a malformed header is received. (#8101)
- twisted.web.http.Request once again has a reference to the
HTTPFactory which created it, the absence of which was preventing
log messages from being created. (#8272)
- twisted.web.http.HTTPChannel no longer processes requests that have
invalid headers as the final header in their header block. (#8317)
- twisted.web.client.HTTPClientFactory (and the getPage and
downloadPage APIs) now timeouts correctly on TLS connections where
the remote party is not responding on the connection. (#8318)

strports definition, now gives the correct error message when an
empty chain file is given. (#8222)
Improved Documentation
----------------------
- The Twisted Project has adopted the Contributor Covenant as its

Twisted Core 15.2.0 (2015-05-18)
================================
Features
--------
- twisted.internet.process has now been ported to Python 3. (#5987)
- twisted.cred.credentials is now ported to Python 3. (#6176)
- twisted.trial.unittest.TestCase's assertEqual, assertTrue, and
assertFalse methods now pass through the standard library's more
informative failure messages. (#6306)
- The new package twisted.logger provides a new, fully tested, and
feature-rich logging framework. The old module twisted.python.log
is now implemented using the new framework. The new logger HOWTO
documents the new framework. (#6750)
- twisted.python.modules is now ported to Python 3. (#7804)
- twisted.python.filepath.FilePath now supports Unicode (text) paths.
Like the os module, instantiating it with a Unicode path will
return a Unicode-mode FilePath, instantiating with a bytes path
will return a bytes-mode FilePath. (#7805)
- twisted.internet.kqreactor is now ported to Python 3 (#7823)
- twisted.internet.endpoints.ProcessEndpoint is now ported to Python
3. (#7824)
- twisted.python.filepath.FilePath now has asBytesMode and asTextMode
methods which return a FilePath in the requested mode. (#7830)
- twisted.python.components.proxyForInterface now creates method
proxies that can be used with functools.wraps. (#7832)
- The tls optional dependency will now also install the idna package
to validate idna2008 names. (#7853)
Bugfixes
--------
- Don't raise an exception if `DefaultLogObserver.emit()` gets an
event with a message that raises when `repr()` is called on it.
Specifically: use `textFromEventDict()` instead of a separate (and
inferior) message rendering implementation. (#6569)
- twisted.cred.credentials.DigestedCredentials incorrectly handled
md5-sess hashing according to the RFC, which has now been fixed.
(#7835)
- Fixed an issue with twisted.internet.task.LoopingCall.withCount
where sometimes the passed callable would be invoked with "0" when
we got close to tricky floating point boundary conditions. (#7836)
- twisted.internet.defer now properly works with the new logging
system. (#7851)
- Change `messages` key to `log_io` for events generated by
`LoggingFile`. (#7852)
- twisted.logger had literal characters in docstrings that are now
quoted. (#7854)
- twisted.logger now correctly formats a log event with a key named
`message` when passed to a legacy log observer. (#7855)
- twisted.internet.endpoints.HostnameEndpoint now uses getaddrinfo
properly on Python 3.4 and above. (#7886)
Improved Documentation
----------------------
- Fix a typo in narrative documentation for logger (#7875)
Deprecations and Removals
-------------------------
- tkunzip and tapconvert in twisted.scripts were deprecated in 11.0
and 12.1 respectively, and are now removed. (#6747)

twisted.positioning. (#6810)
- twisted.scripts.tap2deb and twisted.scripts.tap2rpm are now
deprecated. (#7682)
- twisted.trial.reporter.TestResult and
twisted.trial.reporter.Reporter contained deprecated methods (since
8.0) which have now been removed. (#7815)

Features
--------

return None from buildProtocol to immediately close the connection.
(#710)
- twisted.trial.unittest.SynchronousTestCase.assertRaises can now
return a context manager. (#5339)
- Implementations of
twisted.internet.interfaces.IStreamClientEndpoint included in
Twisted itself will now handle None being returned from the client
factory's buildProtocol method by immediately closing the
connection and firing the waiting Deferred with a Failure. (#6976)
- inlineCallbacks now supports using the return statement with a
value on Python 3 (#7624)
- twisted.spread.banana.Banana.sendEncoded() now raises a more
informative error message if the user tries to encode objects of

by adding IPushProducer and IConsumer interfaces to its resulting
transport. (#7436)
- twisted.internet.ssl.Certificate(...).getPublicKey().keyHash() now
produces a stable value regardless of OpenSSL version.
Unfortunately this means that it is different than the value
produced by older Twisted versions. (#7651)
- twisted.python.reflect.safe_str on Python 3 converts utf-8 encoded
bytes to clean str instead of "b'a'" (#7660)
- twisted.spread.banana.Banana now raises NotImplementedError when

- twisted.internet.defer.deferredGenerator is now deprecated.
twisted.internet.defer.inlineCallbacks should be used instead.
(#6044)
