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)

  • twisted.names.dns.Message now support rich comparison. (#6848)

Bugfixes

  • twisted.names.server.DNSServerFactory now responds with messages whose flags and fields are reset to their default values instead of copying these from the request. This means that AD and CD flags, and EDNS OPT records in the request are no longer mirrored back to the client. (#6645)

  • twisted.web.client.Agent now verifies that the provided server certificate in a TLS connection is trusted by the platform. (#7042)
  • When requesting an HTTPS URL with twisted.web.client.Agent, the hostname of the presented certificate will be checked against the requested hostname; mismatches will now result in an error rather than a man-in-the-middle opportunity for attackers. This may break existing code that incorrectly depended on insecure behavior, but such code was erroneous and should be updated. (#4888)

Other

  • #5004, #6881, #6956

  • twisted.python.log.FileLogObserver now uses datetime.strftime to format timestamps, adding support for microseconds and timezone offsets to the timeFormat string. (#3513)
  • trial now deterministically runs tests in the order in which they were specified on the command line, instead of quasi-randomly according to dictionary key ordering. (#5520)
  • Cooperator.running can be used to determine the current cooperator status. (#5937)
  • twisted.python.modules.PythonPath now implements __contains__ to allow checking, by name, whether a particular module exists within it. (#6198)

  • 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.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 Web 11.0.0 (2011-04-01)

Features

  • twisted.web._newclient.HTTPParser (and therefore Agent) now handles HTTP headers delimited by bare LF newlines. (#3833)
  • twisted.web.client.downloadPage now accepts the afterFoundGet parameter, with the same meaning as the getPage parameter of the same name. (#4364)
  • twisted.web.xmlrpc.Proxy constructor now takes additional ‘timeout’ and ‘reactor’ arguments. The ‘timeout’ argument defaults to 30 seconds. (#4741)
  • Twisted Web now has a templating system, twisted.web.template, which is a direct, simplified derivative of Divmod Nevow. (#4939)

Bugfixes

  • HTTPPageGetter now adds the port to the host header if it is not the default for that scheme. (#3857)
  • twisted.web.http.Request.write now raises an exception if it is called after response generation has already finished. (#4317)
  • twisted.web.client.HTTPPageGetter and twisted.web.client.getPage now no longer make two requests when using afterFoundGet. (#4760)
  • twisted.web.twcgi no longer adds an extra “content-type” header to CGI responses. (#4786)
  • twisted.web will now properly specify an encoding (UTF-8) on error, redirect, and directory listing pages, so that IE7 and previous will not improperly guess the ‘utf7’ encoding in these cases. Please note that Twisted still sets a default content-type of ‘text/html’, and you shouldn’t rely on that: you should set the encoding appropriately in your application. (#4900)
  • twisted.web.http.Request.setHost now sets the port in the host header if it is not the default. (#4918)
  • default NOT_IMPLEMENTED and NOT_ALLOWED pages now quote the request method and URI respectively, to protect against browsers which don’t quote those values for us. (#4978)

Improved Documentation

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.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)
  • Use correct Twisted version for when cancellation was introduced in the Deferred docstring. (#4614)
  • The logging howto is now more clear about how the standard library logging module and twisted.python.log can be integrated. (#4642)
  • The finger tutorial still had references to .tap files. This reference has now been removed. The documentation clarifies “finger.tap” is a module and not a filename. (#4679)
  • The finger tutorial had a broken link to the twisted.application.service.Service class, which is now fixed. Additionally, a minor typo (‘verison’) was fixed. (#4681)
  • twisted.protocols.policies.TimeoutMixin now has clearer API documentation. (#4684)

  • twisted.web.xmlrpc.XMLRPC.xmlrpc_* methods can now be decorated using withRequest to cause them to be passed the HTTP request object. (#3073)

Bugfixes

  • twisted.web.xmlrpc.QueryProtocol.handleResponse now disconnects from the server, meaning that Twisted XML-RPC clients disconnect from the server as soon as they receive a response, rather than relying on the server to disconnect. (#2518)
  • twisted.web.twcgi now generates responses containing all occurrences of duplicate headers produced by CGI scripts, not just the last value. (#4742)

Bugfixes

  • twisted.words.protocols.irc.IRCClient no longer invokes privmsg() in the default noticed() implementation. (#4419)
  • twisted.words.im.ircsupport.IRCProto now sends the correct name in the USER command. (#4641)

Deprecations and Removals

  • Remove twisted.words.im.proxyui and twisted.words.im.tap. (#1823)

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)

  • The ‘cftp’ command-line tool will no longer encounter an intermittent error, crashing at startup with a ZeroDivisionError while trying to report progress. (#4463)
  • twisted.conch.ssh.connection.SSHConnection now replies to requests to open an unknown channel with an OPEN_UNKNOWN_CHANNEL_TYPE message instead of closing the connection. (#4490)

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 noticeably 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)

  • 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)

  • The ‘wsgi.input’ WSGI environment object now supports -1 and None as arguments to the read and readlines methods. (#4114)
  • twisted.web.wsgi doesn’t unquote QUERY_STRING anymore, thus complying with the WSGI reference implementation. (#4143)
  • The HTTP proxy will no longer pass on keep-alive request headers from the client, preventing pages from loading then “hanging” (leaving the connection open with no hope of termination). (#4179)

Deprecations and Removals

  • Attempting to write unicode data to process pipes on Windows will no longer result in arbitrarily encoded messages being written to the pipe, but instead will immediately raise an error (#3930)
  • The various twisted command line utilities will no longer print ModuleType.__doc__ when Twisted was installed with setuptools (#4030)

Fixes

  • Parse UNSEEN response data and include it in the result of IMAP4Client.examine (#3550)

  • A case where the SMTP client could skip some recipients when retrying delivery has been fixed (#3638)

  • Escape sequences inside quoted strings in IMAP4 should now be parsed correctly by the IMAP4 server protocol (#3659)
  • The “imap4-utf-7” codec that is registered by twisted.mail.imap4 had a number of fixes that allow it to work better with the Python codecs system, and to actually work (#3663)

  • request.content should now always be seeked to the beginning when request.process is called, so application code should never need to seek back manually (#3585)
  • Fetching a child of static.File with a double-slash in the URL (such as “example//foo.html”) should now return a 404 instead of a traceback and 500 error (#3631)
  • downloadPage will now fire a Failure on its returned Deferred instead of indicating success when the connection is prematurely lost (#3645)

  • microdom should now serialize namespaces correctly (#3672)
  • The HTTP Auth support resource wrapper should no longer corrupt requests and cause them to skip a segment in the request path (#3679)

  • WSGI applications should now be able to handle requests with large bodies (#4029)
  • Exceptions raised from WSGI applications should now more reliably be turned into 500 errors on the HTTP level (#4019)
  • DeferredResource now correctly passes through exceptions raised from the wrapped resource, instead of turning them all into 500 errors (#3932)
  • Agent.request now generates a Host header when no headers are passed at (#4131)

  • The IRC client will now dispatch “RPL MOTD” messages received before a “RPL MOTD START” instead of raising an exception (#3676)
  • The IRC client protocol implementation no longer updates its ‘nickname’ attribute directly; instead, that attribute will be updated when the server acknowledges the change (#3377)
  • The IRC client protocol implementation now supports falling back to another nickname when a nick change request fails (#3377, #4010)

Deprecations and Removals

  • The TOC protocol implementation is now deprecated, since the protocol itself has been deprecated and obselete for quite a long time (#3580)
  • The gui “im” application has been removed, since it relied on GTK1, which is hard to find these days (#3699, #3340)
