Twisted Core 14.0.0 (2014-05-08)
================================
Features
--------
- twisted.internet.interfaces.IUDPTransport - and that interface's
implementations in Twisted - now supports enabling broadcasting.
(#454)
- trial's TestCase will now report a test method as an error if that
test method is a generator function, preventing an issue when a
user forgets to decorate a test method with defer.inlineCallbacks,
causing the test method to not run. (#3917)
- twisted.positioning, a new API for positioning systems such as GPS,
has been added. It comes with an implementation of NMEA, the most
common wire protocol for GPS devices. It will supersede
twisted.protoocols.gps. (#3926)
- The new interface twisted.internet.interfaces.IStreamClientEndpoint
StringParserWithReactor will supply the reactor to its
parseStreamClient method, passed along from
twisted.internet.endpoints.clientFromString. (#5069)
- IReactorUDP.listenUDP, IUDPTransport.write and
IUDPTransport.connect now accept ipv6 address literals. (#5086)
- A new API, twisted.internet.ssl.optionsForClientTLS, allows clients
to specify and verify the identity of the peer they're communicating
with. When used with the service_identity library from PyPI, this
provides support for service identity verification from RFC 6125, as
well as server name indication from RFC 6066. (#5190)
- Twisted's TLS support now provides a way to ask for user-configured
trust roots rather than having to manually configure such
certificate authority certificates yourself.
twisted.internet.ssl.CertificateOptions now accepts a new argument,
trustRoot, which combines verification flags and trust sources, as
well as a new function that provides a value for that argument,
twisted.internet.ssl.platformTrust, which allows using the trusted
platform certificate authorities from OpenSSL for certificate
verification. (#5446)
- Constants are now comparable/orderable based on the order in which
they are defined. (#6523)
- "setup.py install" and "pip install" now work on Python 3.3,
installing the subset of Twisted that has been ported to Python 3.
(#6539)
- twisted.internet.ssl.CertificateOptions now supports ECDHE for
servers by default on pyOpenSSL 0.14 and later, if the underlying
versions of cryptography.io and OpenSSL support it. (#6586)
- twisted.internet.ssl.CertificateOptions now allows the user to set
acceptable ciphers and uses secure ones by default. (#6663)
- The Deferred returned by
twisted.internet.defer.DeferredFilesystemLock.deferUntilLocked can
now be cancelled. (#6720)
- twisted.internet.ssl.CertificateOptions now enables TLSv1.1 and
TLSv1.2 by default (in addition to TLSv1.0) if the underlying
version of OpenSSL supports these protocol versions. (#6772)
- twisted.internet.ssl.CertificateOptions now supports Diffie-Hellman
key exchange. (#6799)
- twisted.internet.ssl.CertificateOptions now disables TLS
compression to avoid CRIME attacks and, for servers, uses server
preference to choose the cipher. (#6801)
- SSL server endpoint string descriptions now support the
specification of Diffie-Hellman key exchange parameter files.
(#6924)
- twisted.python.reflect.requireModule was added to handle
conditional imports of python modules and work around pyflakes
warnings of unused imports code. (#7014)
Bugfixes
--------
- If a ProcessProtocol.processExited method raised an exception a
broken process handler would be left in the global process state
leading to errors later on. This has been fixed and now an error
will be logged instead. (#5151)
- Twisted now builds on Solaris. Note that lacking a Buildbot slave
(see http://buildbot.twistedmatrix.com/boxes-supported) Solaris is
not a supported Twisted platform. (#5728)
- twisted.internet.utils is now correctly installed on Python 3.
(#6929)
- twisted.python.threadpool.ThreadPool no longer starts new workers
when its pool size is changed while the pool is not running.
(#7011)
Improved Documentation
----------------------
- Twisted now uses the Sphinx documentation generator for its
narrative documentation, which means that the source format for
narrative documentation has been converted to ReStructuredText.
(#4500)
- The Sphinx documentation is now also configured to allow
intersphinx links to standard library documentation. (#4582)
- The docstring for twisted.internet.task.react now better documents
the main parameter (#6071)
- The writing standard now explicitly mandates the usage of
ungendered pronouns. (#6858)
Deprecations and Removals
-------------------------
- test_import.py was removed as it was redundant. (#2053)
- Support for versions of pyOpenSSL older than 0.10 has been removed.
Affected users should upgrade pyOpenSSL. (#5014)
- twisted.internet.interfaces.IStreamClientEndpointStringParser is
now deprecated in favor of twisted.internet.interfaces.IStreamClien
tEndpointStringParserWithReactor. (#5069)
- unsignedID and setIDFunction, previously part of
twisted.python.util and deprecated since 13.0, have now been
removed. (#6707)
- FTPClient.changeDirectory was deprecated in 8.2 and is now removed.
(#6759)
- twisted.internet.stdio.StandardIO.closeStdin, an alias for
loseWriteConnection only available on POSIX and deprecated since
2.1, has been removed. (#6785)
- twisted.python.reflect.getcurrent is now deprecated and must not be
used. twisted.python.reflect.isinst is now deprecated in favor of
the built-in isinstance. (#6859)

requiring a factory. (#5270)
- twisted.trial.unittest.SynchronousTestCase.assertNoResult no longer
swallows the result, if the assertion succeeds. (#6291)

Twisted Core 13.0.0 (2013-03-19)
================================
Features
--------
- The twisted.protocols.ftp.FTP server now treats "LIST -La", "LIST
-al", and all other combinations of ordering and case of the "-l"
and "-a" flags the same: by ignoring them rather than treating them

on PyPy. (#6216)
- All reactors included in Twisted itself now gracefully handle a
rare case involving delayed calls scheduled very far in the future.
(#6259)
- twisted.trial.reporter.Reporter._trimFrames correctly removes
frames from twisted.internet.utils.runWithWarningsSuppressed again,
after being broke in #6009. (#6282)

Twisted Core 12.0.0 (2012-02-10)
================================
Features
--------
- The interface argument to IReactorTCP.listenTCP may now be an IPv6
address literal, allowing the creation of IPv6 TCP servers. (#5084)
- twisted.python.constants.Names now provides a way to define
collections of named constants, similar to the "enum type" feature
of C or Java. (#5382)
- twisted.python.constants.Values now provides a way to define
collections of named constants with arbitrary values. (#5383)
Bugfixes

- Fixed an obscure case where connectionLost wasn't called on the
protocol when using half-close. (#3037)
- UDP ports handle socket errors better on Windows. (#3396)
- When idle, the gtk2 and glib2 reactors no longer wake up 10 times a
second. (#4376)
- Prevent a rare situation involving TLS transports, where a producer
may be erroneously left unpaused. (#5347)

connection has been lost. (#5439)
- twisted.protocols.htb.Bucket now empties properly with a non-zero
drip rate. (#5448)
- IReactorSSL and ITCPTransport.startTLS now synchronously propagate
errors from the getContext method of context factories, instead of
being capturing them and logging them as unhandled. (#5449)

Twisted Core 11.1.0 (2011-11-15)
================================
Features
--------
- TCP and TLS transports now support abortConnection() which, unlike
loseConnection(), always closes the connection immediately. (#78)
- Failures received over PB when tracebacks are disabled now display
the wrapped exception value when they are printed. (#581)
- twistd now has a --logger option, allowing the use of custom log
observers. (#638)
- The default reactor is now poll(2) on platforms that support it.
(#2234)
- twisted.internet.defer.inlineCallbacks(f) now raises TypeError when
f returns something other than a generator or uses returnValue as a
non-generator. (#2501)
- twisted.python.usage.Options now supports performing Zsh tab-
completion on demand. Tab-completion for Twisted commands is
supported out-of-the-box on any recent zsh release. Third-party
commands may take advantage of zsh completion by copying the
provided stub file. (#3078)
- twisted.protocols.portforward now uses flow control between its
client and server connections to avoid having to buffer an
unbounded amount of data when one connection is slower than the
other. (#3350)
- On Windows, the select, IOCP, and Gtk2 reactors now implement
IReactorWin32Events (most notably adding support for serial ports
to these reactors). (#4862)
- twisted.python.failure.Failure no longer captures the state of
locals and globals of all stack frames by default, because it is
expensive to do and rarely used. You can pass captureVars=True to
Failure's constructor if you want to capture this data. (#5011)
- twisted.web.client now supports automatic content-decoding via
twisted.web.client.ContentDecoderAgent, gzip being supported for
now. (#5053)
- Protocols may now implement ILoggingContext to customize their
logging prefix. twisted.protocols.policies.ProtocolWrapper and the
endpoints wrapper now take advantage of this feature to ensure the
application protocol is still reflected in logs. (#5062)
- AMP's raw message-parsing performance was increased by
approximately 12%. (#5075)
- Twisted is now installable on PyPy, because some incompatible C
extensions are no longer built. (#5158)
- twisted.internet.defer.gatherResults now accepts a consumeErrors
parameter, with the same meaning as the corresponding argument for
DeferredList. (#5159)
- Added RMD (remove directory) support to the FTP client. (#5259)
- Server factories may now implement ILoggingContext to customize the
name that is logged when the reactor uses one to start listening on
a port. (#5292)
- The implementations of ITransport.writeSequence will now raise
TypeError if passed unicode strings. (#3896)
- iocp reactor now operates correctly on 64 bit Python runtimes.
(#4669)
- twistd ftp now supports the cred plugin. (#4752)
- twisted.python.filepath.FilePath now has an API to retrieve the
permissions of the underlying file, and two methods to determine
whether it is a block device or a socket. (#4813)
- twisted.trial.unittest.TestCase is now compatible with Python 2.7's
assertDictEqual method. (#5291)
Bugfixes
--------
- The IOCP reactor now does not try to erroneously pause non-
streaming producers. (#745)
- Unicode print statements no longer blow up when using Twisted's
logging system. (#1990)
- Process transports on Windows now support the `writeToChild` method
(but only for stdin). (#2838)
- Zsh tab-completion of Twisted commands no longer relies on
statically generated files, but instead generates results on-the-
fly - ensuring accurate tab-completion for the version of Twisted
actually in use. (#3078)
- LogPublishers don't use the global log publisher for reporting
broken observers anymore. (#3307)
- trial and twistd now add the current directory to sys.path even
when running as root or on Windows. mktap, tapconvert, and
pyhtmlizer no longer add the current directory to sys.path. (#3526)
- twisted.internet.win32eventreactor now stops immediately if
reactor.stop() is called from an IWriteDescriptor.doWrite
implementation instead of delaying shutdown for an arbitrary period
of time. (#3824)
- twisted.python.log now handles RuntimeErrors more gracefully, and
always restores log observers after an exception is raised. (#4379)
- twisted.spread now supports updating new-style RemoteCache
instances. (#4447)
- twisted.spread.pb.CopiedFailure will no longer be thrown into a
generator as a (deprecated) string exception but as a
twisted.spread.pb.RemoteException. (#4520)
- trial now gracefully handles the presence of objects in sys.modules
which respond to attributes being set on them by modifying
sys.modules. (#4748)
- twisted.python.deprecate.deprecatedModuleAttribute no longer
spuriously warns twice when used to deprecate a module within a
package. This should make it easier to write unit tests for
deprecated modules. (#4806)
- When pyOpenSSL 0.10 or newer is available, SSL support now uses
Twisted for all I/O and only relies on OpenSSL for cryptography,
avoiding a number of tricky, potentially broken edge cases. (#4854)
- IStreamClientEndpointStringParser.parseStreamClient now correctly
describes how it will be called by clientFromString (#4956)
- twisted.internet.defer.Deferreds are 10 times faster at handling
exceptions raised from callbacks, except when setDebugging(True)
has been called. (#5011)
- twisted.python.filepath.FilePath.copyTo now raises OSError(ENOENT)
if the source path being copied does not exist. (#5017)
- twisted.python.modules now supports iterating over namespace
packages without yielding duplicates. (#5030)
- reactor.spawnProcess now uses the resource module to guess the
maximum possible open file descriptor when /dev/fd exists but gives
incorrect results. (#5052)
- The memory BIO TLS/SSL implementation now supports producers
correctly. (#5063)
- twisted.spread.pb.Broker no longer creates an uncollectable
reference cycle when the logout callback holds a reference to the
client mind object. (#5079)
- twisted.protocols.tls, and SSL/TLS support in general, now do clean
TLS close alerts when disconnecting. (#5118)
- twisted.persisted.styles no longer uses the deprecated allYourBase
function (#5193)
- Stream client endpoints now start (doStart) and stop (doStop) the
factory passed to the connect method, instead of a different
implementation-detail factory. (#5278)
- SSL ports now consistently report themselves as SSL rather than TCP
when logging their close message. (#5292)
- Serial ports now deliver connectionLost to the protocol when
closed. (#3690)
- win32eventreactor now behaves better in certain rare cases in which
it previously would have failed to deliver connection lost
notification to a protocol. (#5233)
Improved Documentation
----------------------
- Test driven development with Twisted and Trial is now documented in
a how-to. (#2443)
- A new howto-style document covering twisted.protocols.amp has been
added. (#3476)
- Added sample implementation of a Twisted push producer/consumer
system. (#3835)
- The "Deferred in Depth" tutorial now includes accurate output for
the deferred_ex2.py example. (#3941)
- The server howto now covers the Factory.buildProtocol method.
(#4761)
- The testing standard and the trial tutorial now recommend the
`assertEqual` form of assertions rather than the `assertEquals` to
coincide with the standard library unittest's preference. (#4989)
- twisted.python.filepath.FilePath's methods now have more complete
API documentation (docstrings). (#5027)
- The Clients howto now uses buildProtocol more explicitly, hopefully
making it easier to understand where Protocol instances come from.
(#5044)
Deprecations and Removals
-------------------------
- twisted.internet.interfaces.IFinishableConsumer is now deprecated.
(#2661)
- twisted.python.zshcomp is now deprecated in favor of the tab-
completion system in twisted.python.usage (#3078)

Twisted Core 11.0.0 (2011-04-01)
================================
Features
--------
- The reactor is not restartable, but it would previously fail to
complain. Now, when you restart an unrestartable reactor, you get
an exception. (#2066)
- twisted.plugin now only emits a short log message, rather than a
full traceback, if there is a problem writing out the dropin cache
file. (#2409)
- Added a 'replacement' parameter to the
'twisted.python.deprecate.deprecated' decorator. This allows
deprecations to unambiguously specify what they have been
deprecated in favor of. (#3047)
- Added access methods to FilePath for FilePath.statinfo's st_ino,
st_dev, st_nlink, st_uid, and st_gid fields. This is in
preparation for the deprecation of FilePath.statinfo. (#4712)
- IPv4Address and UNIXAddress now have a __hash__ method. (#4783)
- twisted.protocols.ftp.FTP.ftp_STOR now catches `FTPCmdError`s
raised by the file writer, and returns the error back to the
client. (#4909)
Bugfixes
--------
- twistd will no longer fail if a non-root user passes --uid 'myuid'
as a command-line argument. Instead, it will emit an error message.
(#3172)
- IOCPReactor now sends immediate completions to the main loop
(#3233)
- trial can now load test methods from multiple classes, even if the
methods all happen to be inherited from the same base class.
(#3383)
- twisted.web.server will now produce a correct Allow header when a
particular render_FOO method is missing. (#3678)
- HEAD requests made to resources whose HEAD handling defaults to
calling render_GET now always receive a response with no body.
(#3684)
- trial now loads decorated test methods whether or not the decorator
preserves the original method name. (#3909)
- t.p.amp.AmpBox.serialize will now correctly consistently complain
when being fed Unicode. (#3931)
- twisted.internet.wxreactor now supports stopping more reliably.
(#3948)
- reactor.spawnProcess on Windows can now handle ASCII-encodable
Unicode strings in the system environment (#3964)
- When C-extensions are not complied for twisted, on python2.4, skip
a test in twisted.internet.test.test_process that may hang due to a
SIGCHLD related problem. Running 'python setup.py build_ext
--inplace' will compile the extension and cause the test to both
run and pass. (#4331)
- twisted.python.logfile.LogFile now raises a descriptive exception
when passed a log directoy which does not exist. (#4701)
- Fixed a bug where Inotify will fail to add a filepatch to watchlist
after it has been added/ignored previously. (#4708)
- IPv4Address and UNIXAddress object comparison operators fixed
(#4817)
- twisted.internet.task.Clock now sorts the list of pending calls
before and after processing each call (#4823)
- ConnectionLost is now in twisted.internet.error.__all__ instead of
twisted.words.protocols.jabber.xmlstream.__all__. (#4856)
- twisted.internet.process now detects the most appropriate mechanism
to use for detecting the open file descriptors on a system, getting
Twisted working on FreeBSD even when fdescfs is not mounted.
(#4881)
- twisted.words.services referenced nonexistent
twisted.words.protocols.irc.IRC_NOSUCHCHANNEL. This has been fixed.
Related code has also received test cases. (#4915)
Improved Documentation
----------------------
- The INSTALL file now lists all of Twisted's dependencies. (#967)
- Added the stopService and startService methods to all finger
example files. (#3375)
- Missing reactor.run() calls were added in the UDP and client howto
documents. (#3834)
- The maxRetries attribute of
twisted.internet.protocols.RetryingClientFactory now has API
documentation. (#4618)
- Lore docs pointed to a template that no longer existed, this has
been fixed. (#4682)
- The `servers` argument to `twisted.names.client.createResolver` now
has more complete API documentation. (#4713)
- Linked to the Twisted endpoints tutorial from the Twisted core
howto list. (#4773)
- The Endpoints howto now links to the API documentation. (#4774)
- The Quotes howto is now more clear in its PYTHONPATH setup
instructions. (#4785)
- The API documentation for DeferredList's fireOnOneCallback
parameter now gives the correct order of the elements of the result
tuple. (#4882)
Deprecations and Removals
-------------------------
- returning a value other than None from IProtocol.dataReceived was
deprecated (#2491)
- Deprecated the --extra option in trial. (#3372)
- twisted.protocols._c_urlarg has been removed. (#4162)

deprecated since Twisted 2.5. (#4547)
- __getitem__ __getslice__ and __eq__ (tuple comparison, indexing)
removed from twisted.internet.address.IPv4Address and
twisted.internet.address.UNIXAddress classes UNIXAddress and
IPv4Address properties _bwHack are now deprecated in
twisted.internet.address (#4817)
- twisted.python.reflect.allYourBase is now no longer used, replaced
with inspect.getmro (#4928)
- allYourBase and accumulateBases are now deprecated in favor of
inspect.getmro. (#4946)

Twisted Core 10.2.0 (2010-11-29)
================================
Features
--------
- twisted.internet.cfreactor has been significantly improved. It now
runs, and passes, the test suite. Many, many bugs in it have been
fixed, including several segfaults, as it now uses PyObjC and
longer requires C code in Twisted. (#1833)
- twisted.protocols.ftp.FTPRealm now accepts a parameter to override
"/home" as the container for user directories. The new
BaseFTPRealm class in the same module also allows easy
implementation of custom user directory schemes. (#2179)
- twisted.python.filepath.FilePath and twisted.python.zippath.ZipPath
now have a descendant method to simplify code which calls the child
method repeatedly. (#3169)
- twisted.python.failure._Frame objects now support fake f_locals
attribute. (#4045)
- twisted.internet.endpoints now has 'serverFromString' and
'clientFromString' APIs for constructing endpoints from descriptive
strings. (#4473)
- The default trial reporter now combines reporting of tests with the
same result to shorten its summary output. (#4487)
- The new class twisted.protocols.ftp.SystemFTPRealm implements an
FTP realm which uses system accounts to select home directories.
(#4494)
- twisted.internet.reactor.spawnProcess now wastes less time trying
to close non-existent file descriptors on POSIX platforms. (#4522)
- twisted.internet.win32eventreactor now declares that it implements
a new twisted.internet.interfaces.IReactorWin32Events interface.
(#4523)
- twisted.application.service.IProcess now documents its attributes
using zope.interface.Attribute. (#4534)
- twisted.application.app.ReactorSelectionMixin now saves the value
of the --reactor option in the "reactor" key of the options object.
(#4563)
- twisted.internet.endpoints.serverFromString and clientFromString,
and therefore also twisted.application.strports.service, now
support plugins, so third parties may implement their own endpoint
types. (#4695)
Bugfixes
--------
- twisted.internet.defer.Deferred now handles chains iteratively
instead of recursively, preventing RuntimeError due to excessive
recursion when handling long Deferred chains. (#411)
- twisted.internet.cfreactor now works with trial. (#2556)
- twisted.enterprise.adbapi.ConnectionPool.close may now be called
even if the connection pool has not yet been started. This will
prevent the pool from ever starting. (#2680)
- twisted.protocols.basic.NetstringReceiver raises
NetstringParseErrors for invalid netstrings now. It handles empty
netstrings ("0:,") correctly, and the performance for receiving
netstrings has been improved. (#4378)
- reactor.listenUDP now returns an object which declares that it
implements IListeningPort. (#4462)
- twisted.python.randbytes no longer uses PyCrypto as a secure random
number source (since it is not one). (#4468)
- twisted.internet.main.installReactor now blocks installation of
another reactor when using python -O (#4476)
- twisted.python.deprecate.deprecatedModuleAttribute now emits only
one warning when used to deprecate a package attribute which is a
module. (#4492)
- The "brief" mode of twisted.python.failure.Failure.getTraceback now
handles exceptions raised by the underlying exception's __str__
method. (#4501)
- twisted.words.xish.domish now correctly parses XML with namespaces
which include whitespace. (#4503)
- twisted.names.authority.FileAuthority now generates correct
negative caching hints, marks its referral NS RRs as non-
authoritative, and correctly generates referrals for ALL_RECORDS
requests. (#4513)
- twisted.internet.test.reactormixins.ReactorBuilder's attribute
`requiredInterface` (which should an interface) is now
`requiredInterfaces` (a list of interfaces) as originally described
per the documentation. (#4527)
- twisted.python.zippath.ZipPath.__repr__ now correctly formats paths
with ".." in them (by including it). (#4535)
- twisted.names.hosts.searchFileFor has been fixed against
refcounting dependency. (#4540)
- The POSIX process transports now declare that they implement
IProcessTransport. (#4585)
- Twisted can now be built with the LLVM clang compiler, with
'CC=clang python setup.py build'. C code that caused errors with
this compiler has been removed. (#4652)
- trial now puts coverage data in the path specified by --temp-
directory, even if that option comes after --coverage on the
command line. (#4657)
- The unregisterProducer method of connection-oriented transports
will now cause the connection to be closed if there was a prior
call to loseConnection. (#4719)
- Fixed an issue where the new StreamServerEndpointService didn't log
listen errors. (This was a bug not present in any previous
releases, as this class is new.) (#4731)
Improved Documentation
----------------------
- The trial man page now documents the meaning of the final line of
output of the default reporter. (#1384)
- The API documentation for twisted.internet.defer.DeferredList now
goes into more depth about the effects each of the __init__ flags
that class accepts. (#3595)
- There is now narrative documentation for the endpoints APIs, in the
'endpoints' core howto, as well as modifications to the 'writing
clients' and 'writing servers' core howto documents to indicate
that endpoints are now the preferred style of listening and
connecting. (#4478)
- trial's man page now documents the --disablegc option in more
detail. (#4511)
- trial's coverage output format is now documented in the trial man
page. (#4512)
- Broken links and spelling errors in the finger tutorial are now
fixed. (#4516)
- twisted.internet.threads.blockingCallFromThread's docstring is now
explicit about Deferred support. (#4517)
- twisted.python.zippath.ZipPath.child now documents its handling of
".." (which is not special, making it different from
FilePath.child). (#4535)
- The API docs for twisted.internet.defer.Deferred now cover several
more of its (less interesting) attributes. (#4538)
- LineReceiver, NetstringReceiver, and IntNStringReceiver from
twisted.protocols.basic now have improved API documentation for
read callbacks and write methods. (#4542)
- Tidied up the Twisted Conch documentation for easier conversion.
(#4566)

Twisted Core 10.1.0 (2010-06-27)
================================
Features
--------
- Add linux inotify support, allowing monitoring of file system
events. (#972)
- Deferreds now support cancellation. (#990)
- Added new "endpoint" interfaces in twisted.internet.interfaces,
which abstractly describe stream transport endpoints which can be
listened on or connected to. Implementations for TCP and SSL
clients and servers are present in twisted.internet.endpoints.
Notably, client endpoints' connect() methods return cancellable
Deferreds, so code written to use them can bypass the awkward
"ClientFactory.clientConnectionFailed" and
"Connector.stopConnecting" methods, and handle errbacks from or
cancel the returned deferred, respectively. (#1442)
- twisted.protocols.amp.Integer's documentation now clarifies that
integers of arbitrary size are supported and that the wire format
is a base-10 representation. (#2650)
- twisted.protocols.amp now includes support for transferring
timestamps (amp.DateTime) and decimal values (amp.Decimal). (#2651)
- twisted.protocol.ftp.IWriteFile now has a close() method, which can
return a Deferred. Previously a STOR command would finish
immediately upon the receipt of the last byte of the uploaded file.
With close(), the backend can delay the finish until it has
performed some other slow action (like storing the data to a
virtual filesystem). (#3462)
- FilePath now calls os.stat() only when new status information is
required, rather than immediately when anything changes. For some
applications this may result in fewer stat() calls. Additionally,
FilePath has a new method, 'changed', which applications may use to
indicate that the FilePath may have been changed on disk and
therefore the next status information request must fetch a new
stat result. This is useful if external systems, such as C
libraries, may have changed files that Twisted applications are
referencing via a FilePath. (#4130)
- Documentation improvements are now summarized in the NEWS file.
(#4224)
- twisted.internet.task.deferLater now returns a cancellable
Deferred. (#4318)
- The connect methods of twisted.internet.protocol.ClientCreator now
return cancellable Deferreds. (#4329)
- twisted.spread.pb now has documentation covering some of its
limitations. (#4402)
- twisted.spread.jelly now supports jellying and unjellying classes
defined with slots if they also implement __getstate__ and
__setstate__. (#4430)
- twisted.protocols.amp.ListOf arguments can now be specified as
optional. (#4474)
Bugfixes
--------
- On POSIX platforms, reactors now support child processes in a way
which doesn't cause other syscalls to sometimes fail with EINTR (if
running on Python 2.6 or if Twisted's extension modules have been
built). (#733)
- Substrings are escaped before being passed to a regular expression
for searching to ensure that they don't get interpreted as part of
the expression. (#1893)
- twisted.internet.stdio now supports stdout being redirected to a
normal file (except when using epollreactor). (#2259)
- (#2367)
- The tap2rpm script now works with modern versions of RPM. (#3292)
- twisted.python.modules.walkModules will now handle packages
explicitly precluded from importing by a None placed in
sys.modules. (#3419)
- ConnectedDatagramPort now uses stopListening when a connection
fails instead of the deprecated loseConnection. (#3425)
- twisted.python.filepath.FilePath.setContent is now safe for
multiple processes to use concurrently. (#3694)
- The mode argument to the methods of
twisted.internet.interfaces.IReactorUNIX is no longer deprecated.
(#4078)
- Do not include blacklisted projects when generating NEWS. (#4190)
- When generating NEWS for a project that had no significant changes,
include a section for that project and say that there were no
interesting changes. (#4191)
- Redundant 'b' mode is no longer passed to calls to FilePath.open
and FilePath.open itself now corrects the mode when multiple 'b'
characters are present, ensuring only one instance of 'b' is
provided, as a workaround for http://bugs.python.org/issue7686.
(#4207)
- HTML tags inside <pre> tags in the code snippets are now escaped.
(#4336)
- twisted.protocols.amp.CommandLocator now allows subclasses to
override responders inherited from base classes. (#4343)
- Fix a bunch of small but important defects in the INSTALL, README
and so forth. (#4346)
- The poll, epoll, glib2, and gtk2 reactors now all support half-
close in the twisted.internet.stdio.StandardIO transport. (#4352)
- twisted.application.internet no longer generates an extra and
invalid entry in its __all__ list for the nonexistent
MulticastClient. (#4373)
- Choosing a reactor documentation now says that only the select-
based reactor is a truly cross-platform reactor. (#4384)
- twisted.python.filepath.FilePath now no longer leaves files open,
to be closed by the garbage collector, when an exception is raised
in the implementation of setContent, getContent, or copyTo. (#4400)
- twisted.test.proto_helpers.StringTransport's getHost and getPeer
methods now return IPv4Address instances by default. (#4401)
- twisted.protocols.amp.BinaryBoxProtocol will no longer deliver an
empty string to a switched-to protocol's dataReceived method when
the BinaryBoxProtocol's buffer happened to be empty at the time of
the protocol switch. (#4405)
- IReactorUNIX.listenUNIX implementations now support abstract
namespace sockets on Linux. (#4421)
- Files opened with FilePath.create() (and therefore also files
opened via FilePath.open() on a path with alwaysCreate=True) will
now be opened in binary mode as advertised, so that they will
behave portably across platforms. (#4453)
- The subunit reporter now correctly reports import errors as errors,
rather than by crashing with an unrelated error. (#4496)
Improved Documentation
----------------------
- The finger tutorial example which introduces services now avoids
double-starting the loop to re-read its users file. (#4420)
- twisted.internet.defer.Deferred.callback's docstring now mentions
the implicit chaining feature. (#4439)
- doc/core/howto/listing/pb/chatclient.py can now actually send a
group message. (#4459)
Deprecations and Removals
-------------------------
- twisted.internet.interfaces.IReactorArbitrary,
twisted.application.internet.GenericServer, and
twisted.application.internet.GenericClient are now deprecated.
(#367)

which has been deprecated (doesn't say since when), as well as
support for the legacy
twisted.application.app.ApplicationRunner.getLogObserver method.
(#4092)
- twisted.application.app.reportProfile has been removed. (#4093)
- twisted.application.app.getLogFile has been removed. (#4094)

Twisted Core 10.0.0 (2010-03-01)
================================
Features
--------
- The twistd man page now has a SIGNALS section. (#689)
- reactor.spawnProcess now will not emit a PotentialZombieWarning
when called before reactor.run, and there will be no potential for
zombie processes in this case. (#2078)
- High-throughput applications based on Perspective Broker should now
run noticably faster thanks to the use of a more efficient decoding
function in Twisted Spread. (#2310)
- Documentation for trac-post-commit-hook functionality in svn-dev
policy. (#3867)
- twisted.protocols.socks.SOCKSv4 now supports the SOCKSv4a protocol.
(#3886)
- Trial can now output test results according to the subunit
protocol, as long as Subunit is installed (see
https://launchpad.net/subunit). (#4004)
- twisted.protocols.amp now provides a ListOf argument type which can
be composed with some other argument types to create a zero or more
element sequence of that type. (#4116)
- If returnValue is invoked outside of a function decorated with
@inlineCallbacks, but causes a function thusly decorated to exit, a
DeprecationWarning will be emitted explaining this potentially
confusing behavior. In a future release, this will cause an
exception. (#4157)
- twisted.python.logfile.BaseLogFile now has a reopen method allowing
you to use an external logrotate mechanism. (#4255)
Bugfixes
--------
- FTP.ftp_NLST now handles requests on invalid paths in a way
consistent with RFC 959. (#1342)
- twisted.python.util.initgroups now calls the low-level C initgroups
by default if available: the python version can create lots of I/O
with certain authentication setup to retrieve all the necessary
information. (#3226)
- startLogging now does nothing on subsequent invocations, thus
fixing a terrible infinite recursion bug that's only on edge case.
(#3289)
- Stringify non-string data to NetstringReceiver.sendString before
calculating the length so that the calculated length is equal to
the actual length of the transported data. (#3299)
- twisted.python.win32.cmdLineQuote now correctly quotes empty
strings arguments (#3876)
- Change the behavior of the Gtk2Reactor to register only one source
watch for each file descriptor, instead of one for reading and one
for writing. In particular, it fixes a bug with Glib under Windows
where we failed to notify when a client is connected. (#3925)
- Twisted Trial no longer crashes if it can't remove an old
_trial_temp directory. (#4020)
- The optional _c_urlarg extension now handles unquote("") correctly
on platforms where malloc(0) returns NULL, such as AIX. It also
compiles with less warnings. (#4142)
- On POSIX, child processes created with reactor.spawnProcess will no
longer automatically ignore the signals which the parent process
has set to be ignored. (#4199)
- All SOCKSv4a tests now use a dummy reactor with a deterministic
resolve method. (#4275)
- Prevent extraneous server, date and content-type headers in proxy
responses. (#4277)
Deprecations and Removals
-------------------------
- twisted.internet.error.PotentialZombieWarning is now deprecated.
(#2078)
- twisted.test.time_helpers is now deprecated. (#3719)

2.5.0 (2006-12-29)
==================
Twisted 2.5.0 is a major feature release, with several interesting new
developments and a great number of bug fixes. Some of the highlights
follow.
* AMP, the Asynchronous Messaging Protocol, was introduced. AMP is
a protocol which provides request/response semantics over a
persistent connection in a very simple and extensible manner.
* An Epoll-based reactor was added, which can be used with twistd or
trial by passing "-r epoll" on the command line. This may improve
performance of certain high-traffic network applications.
* The 'twistd' command can now accept sub-commands which name an
application to run. For example, 'twistd web --path .' will start a
web server serving files out of the current directory. This
functionality is meant to replace the old way of doing things with
'mktap' and 'twistd -f'.
* Python 2.5 is now supported. Previous releases of Twisted were
broken by changes in the release of Python 2.5.
* 'inlineCallbacks' was added, which allows taking advantage of the
new 'yield' expression syntax in Python 2.5 to avoid writing
callbacks for Deferreds.
In addition to these changes, there are many other minor features and
a large number of bug fixes.

2.3.0 (2006-05-14)
==================
Features

Fixes
-----

util.spinUntil, util.spinWhile, util.extract_tb,
util.format_exception, util.suppress_warnings, unittest.wait,
util.wait
- The backwards compatibility layer of twisted.python.components
(e.g., backwardsCompatImplements, fixClassImplements, etc) has been
disabled. The functions still exist, but do nothing as to not break
user code outright (#1511)
- Deprecate the usage of the 'default' argument as a keyword argument
in Interface.__call__. Passing a second positional argument to
specify the default return value of the adaptation is still
supported.

2.1.0 (2005-11-06)
==================
Features
--------
- threadedselectreactor, a reactor which potentially makes
integration with foreign event loops much simpler.
- major improvements to twisted.conch.insults, including many new widgets.
- adbapi ConnectionPools now have 'runWithConnection' which is
similar to runInteraction but gives you a connection object instead of
a transaction. [975]
- __file__ is now usable in tac files
- twisted.cred.pamauth now contains a PAM checker (moved from twisted.conch)
- twisted.protocols.policies.LimitTotalConnectionsFactory now exists,
which does as the name suggests
- twisted.protocols.ident now uses /proc/net/tcp on Linux [233]
- trial now recurses packages by default (a la the old -R parameter)
- (PB) Calling a remote method that doesn't exist now raises
NoSuchMethod instead of AttributeError.
Fixes
-----
- FTP client and server improvements
- Trial improvements: The code is now much simpler, and more stable.
- twisted.protocols.basic.FileSender now works with empty files
- Twisted should now be much more usable on Pythons without thread support.
- minor improvements to process code in win32eventreactor
- twistd -y (--python) now implies -o (--nosave). [539]
- improved lockfile handling especially with respect to unix sockets.
- deferredGenerator now no longer overuses the stack, which sometimes
caused stack overflows.
- Failure.raiseException now at least always raises the correct Exception.
- minor improvements to serialport code
Deprecations
------------
- twisted.python.componts.getAdapter. Use IFoo(o) instead.
- Adapter persistence (IFoo(x, persist=True)). Just don't use it.
- log.debug. It was equivalent to log.msg(), just use that.
- twisted.protocols.telnet. twisted.conch.telnet replaces it.
- Setting a trial reporter using a flag to 'trial'. Instead of 'trial
--bwverbose', for example, use 'trial --reporter=bwverbose'.
- trial --coverage will become a flag in Twisted 2.2.
- passing a fully-qualified python name to --reporter is
deprecated. Pass only names of Reporter plugins.
- trial --psyco.
- trial -R (--recurse) is now the default, so passing it is deprecated.
- trial --reporter-args. Use the plugin system to do this sort of thing.
- trial.assertions.assertionMethod and trial.unittest.assertionMethod
are both deprecated. Use instance methods on TestCases instead.
- trial's deferredResult, deferredError, and wait functions. Return
Deferreds from your test methods instead of using them.
- Raising unittest.SkipTest with no arguments. Give a reason for your skip.
- The Failure returned from a gatherResults and DeferredList is now
of type FirstError instead of a tuple of (Exception, index). It
supports a firstError[idx] syntax but that is deprecated. Use
firstError.subFailure and firstError.index instead.
- whenThreaded now simply calls the passed function synchronously.

the invoking user's UID/GID.
- Removed some functions that were deprecated since Twisted 1.0.
- ZSH tab-completion for twisted commands.
- More correct daemonization in twistd.
- twisted.python.log: do not close the log because of invalid format string.
- Disabled automatic import of cBanana.
- Boolean support for twisted.persisted.marmalade.
- Refactor of plugin and application HOWTO documentation
- Async HOWTO expanded greatly.

- Deferred.setTimeout is now deprecated.
- New defer.DeferredLock/DeferredSemaphore/DeferredQueue.
- Add utils.getProcessOutputAndValue to get stdout/err/value.
- Default DNS resolver is now non-blocking.
- Increased default TCP accept backlog from 5 to 50.
- Make buffering large amounts of TCP data work on Windows.
- Fixed SSL disconnect to not wait for remote host. Fixes issue with firefox.
- Separate state for Deferred finalization so that GC-loops preventing
finalization don't occur.
