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 This is to avoid Python's standard library (which has an out of date idna module) from mis- encoding domain names when non-ASCII Unicode is passed to it.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) Misc ---- - #8133, #8995, #8997, #9003, #9015, #9021, #9026, #9027, #9049, #9057, #9062, #9065, #9069, #9070, #9072, #9074, #9075, #9111, #9117, #9140, #9144, #9145 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) Mail ---- Bugfixes ~~~~~~~~ - twisted.mail.smtp has been ported to Python 3. (#8770) Names ----- Bugfixes ~~~~~~~~ - RRHeader now converts its ttl argument to an integer, raising a TypeError if it cannot. (#8340) Web --- 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) Misc ~~~~ - #8981, #9018, #9067, #9090, #9092, #9093, #9096 Words ----- Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~ - twisted.words.protocols.oscar, which is client code for Oscar/ICQ, was deprecated in 16.2.0 and has now been removed. (#9024) 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 ancilliary 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) Other ----- - #7879, #8583, #8764, #8809, #8859, #8906, #8910, #8913, #8916, #8934, #8945, #8949, #8950, #8952, #8953, #8959, #8962, #8963, #8967, #8975, #8976, #8993, #9013 Twisted Conch 17.1.0 (2017-02-04) ================================= Features -------- - twisted.conch.manhole now works on Python 3. (#8327) - Twisted Conch now supports ECDH key exchanges. (#8730) - Add support in twisted.conch.ssh for hmac-sha2-384 (#8784) - conch and cftp scripts now work on Python 3. (#8791) - twisted.conch.ssh supports ECDH key exchange. (#8811) Bugfixes -------- - twisted.conch.ssh.keys.Key.fromString now supports OpenSSL private keys with Windows line endings (\r\n) again (broken since 16.6.0). (#8928) Improved Documentation ---------------------- - The documentation for twisted.conch.endpoints.SSHCommandClientEndpoint.existingConnection now describes where the value for the connection parameter might come from. (#8892) Other ----- - #8890, #8894, #8957, #8958, #8968 Twisted Mail 17.1.0 (2017-02-04) ================================ Deprecations and Removals ------------------------- - twisted.mail.tap (the twist plugin for mail) no longer accepts the --pop3s option or implicit port numbers to --pop3 and --smtp. This functionality has been deprecated since 11.0. (#8920) Twisted Names 17.1.0 (2017-02-04) ================================= Bugfixes -------- - twisted.names.authority.BindAuthority has been ported to Python 3. (#8880) Twisted News 17.1.0 (2017-02-04) ================================ No significant changes have been made for this release. Twisted Pair 17.1.0 (2017-02-04) ================================ No significant changes have been made for this release. Twisted Runner 17.1.0 (2017-02-04) ================================== Bugfixes -------- - On Python 3, procmon now handles process output without exceptions (#8919) Twisted Web 17.1.0 (2017-02-04) =============================== Features -------- - twisted.web.client.Agent now sets ``Content-Length: 0`` for PUT and POST requests made without a body producer. (#8984) 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. (#8992) Other ----- - #7744, #8909, #8935 Twisted Words 17.1.0 (2017-02-04) ================================= No significant changes have been made for this release. Twisted Core 16.6.0 (2016-11-17) ================================ Features -------- - The twist script can now be run by invoking python -m twisted. (#8657) - twisted.protocols.sip has been ported to Python 3. (#8669) - twisted.persisted.dirdbm has been ported to Python 3. (#8888) Bugfixes -------- - twisted.internet.defer.Deferred now implements send, not __send__, which means that it is now a conforming generator. (#8861) - The IOCP reactor no longer transmits the contents of uninitialized memory when writing large amounts of data. (#8870) - Deferreds awaited/yielded from in a twisted.internet.defer.ensureDeferred wrapped coroutine will now properly raise exceptions. Additionally, it more closely models asyncio.ensure_future and will pass through Deferreds. (#8878) - Deferreds that are paused or chained on other Deferreds will now return a result when yielded/awaited in a twisted.internet.defer .ensureDeferred-wrapped coroutine, instead of returning the Deferred it was chained to. (#8890) Improved Documentation ---------------------- - twisted.test.proto_helpers is now explicitly covered by the compatibility policy. (#8857) Other ----- - #8281, #8823, #8862 Twisted Conch 16.6.0 (2016-11-17) ================================= Features -------- - twisted.conch.ssh.keys supports ECDSA keys (#8798) - scripts/ckeygen can now generate ecdsa keys. (#8828) - ckeygen has been ported to Python 3 (#8855) Deprecations and Removals ------------------------- - twisted.conch.ssh no longer uses gmpy, if available. gmpy is unmaintained, does not have binary wheels for any platforms, and an alternative for higher performance is available in the form of PyPy. (#8079) Twisted Mail 16.6.0 (2016-11-17) ================================ No significant changes have been made for this release. Twisted Names 16.6.0 (2016-11-17) ================================= No significant changes have been made for this release. Twisted News 16.6.0 (2016-11-17) ================================ No significant changes have been made for this release. Twisted Pair 16.6.0 (2016-11-17) ================================ No significant changes have been made for this release. Twisted Runner 16.6.0 (2016-11-17) ================================== No significant changes have been made for this release. Twisted Web 16.6.0 (2016-11-17) =============================== Features -------- - twisted.web.server.Site's HTTP/2 server support now emits vastly fewer WINDOW_UPDATE frames than previously. (#8681) Bugfixes -------- - twisted.web.Agent now tolerates receiving unexpected status codes in the 100 range by discarding them, which is what RFC 7231 recommends doing. (#8885) - twisted.web._http.H2Stream's getHost and getPeer implementations now actually return the host and peer instead of None. (#8893) Twisted Words 16.6.0 (2016-11-17) ================================= Features -------- - twisted.words.protocols.irc has been ported to Python 3 (#6320) Twisted Core 16.5.0 (2016-10-28) ================================ Features -------- - Added twisted.internet.defer.Deferred.addTimeout method to enable timeouts of deferreds. (#5786) - Perspective Broker (the twisted.spread package) has been ported to Python 3 (#7598) - 'yield from' can now be used on Deferreds inside generators, when 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) Other ----- - #4926, #7868, #8209, #8214, #8271, #8308, #8324, #8348, #8367, #8377, #8378, #8379, #8380, #8381, #8383, #8385, #8387, #8388, #8389, #8391, #8392, #8393, #8394, #8397, #8406, #8410, #8412, #8413, #8414, #8421, #8425, #8426, #8430, #8432, #8434, #8435, #8437, #8438, #8439, #8444, #8451, #8452, #8453, #8454, #8456, #8457, #8459, #8462, #8463, #8465, #8468, #8469, #8479, #8482, #8483, #8486, #8490, #8493, #8494, #8496, #8497, #8498, #8499, #8501, #8503, #8504, #8507, #8508, #8510, #8513, #8514, #8515, #8516, #8517, #8520, #8521, #8522, #8523, #8524, #8527, #8528, #8529, #8531, #8532, #8534, #8536, #8537, #8538, #8543, #8544, #8548, #8552, #8553, #8554, #8555, #8557, #8560, #8563, #8565, #8568, #8569, #8572, #8573, #8574, #8580, #8581, #8582, #8586, #8589, #8590, #8592, #8593, #8598, #8603, #8604, #8606, #8609, #8615, #8616, #8617, #8618, #8619, #8621, #8622, #8624, #8627, #8628, #8630, #8632, #8634, #8640, #8644, #8645, #8646, #8647, #8662, #8664, #8666, #8668, #8671, #8672, #8677, #8678, #8684, #8691, #8702, #8705, #8706, #8716, #8719, #8724, #8725, #8727, #8734, #8741, #8749, #8752, #8754, #8755, #8756, #8757, #8758, #8767, #8773, #8776, #8779, #8780, #8785, #8788, #8789, #8790, #8792, #8793, #8799, #8808, #8817, #8839, #8845, #8852 Twisted Conch 16.5.0 (2016-10-28) ================================= Features -------- - SSH key fingerprints can be generated using base64 encoded SHA256 hashes. (#8701) Bugfixes -------- - SSHUserAuthServer does not crash on keyboard interactive authentication when running on Python 3 (#8771) - twisted.conch.insults.insults.ServerProtocol no longer corrupts a client's display when attempting to set the cursor position, and its ECMA-48 terminal manipulation works on Python 3.

Twisted Pair 16.5.0 (2016-10-28) ================================ Features -------- - twisted.pair has been ported to Python 3 (#8744) Twisted Runner 16.5.0 (2016-10-28) ================================== No significant changes have been made for this release. Twisted Web 16.5.0 (2016-10-28) =============================== 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) Other ----- - #8519, #8530, #8629, #8707, #8777, #8778, #8844 Twisted Words 16.5.0 (2016-10-28) ================================= No significant changes have been made for this release. Other ----- - #8360, #8460 Twisted Core 16.4.1 (2016-09-07) ================================ Features -------- - 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, now support ChaCha20 ciphers when available from the OpenSSL on the system. (#8760) Bugfixes -------- - 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 Conch 16.4.1 (2016-09-07) ================================= No significant changes have been made for this release. Twisted Mail 16.4.1 (2016-09-07) ================================ No significant changes have been made for this release. Twisted Names 16.4.1 (2016-09-07) ================================= No significant changes have been made for this release. Twisted News 16.4.1 (2016-09-07) ================================ No significant changes have been made for this release. Twisted Pair 16.4.1 (2016-09-07) ================================ No significant changes have been made for this release. Twisted Runner 16.4.1 (2016-09-07) ================================== No significant changes have been made for this release. Twisted Web 16.4.1 (2016-09-07) =============================== No significant changes have been made for this release. Twisted Words 16.4.1 (2016-09-07) ================================= No significant changes have been made for this release. 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.

(#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.

(#8188) - twisted.trial.unittest.SynchronousTestCase.assertRegex is now available to provide Python 2.7 and Python 3 compatibility. (#8372) Improved Documentation ---------------------- - Development documentation has been updated to refer to Git instead of SVN. (#8335) Deprecations and Removals ------------------------- - twisted.python.reflect's deprecated functions have been removed. This includes funcinfo (deprecated since Twisted 2.5), allYourBase and accumulateBases (deprecated since Twisted 11.0), getcurrent and isinst (deprecated since Twisted 14.0). (#8293) - twisted.scripts.tap2deb and twisted.scripts.tap2rpm (along with the associated executables), deprecated since Twisted 15.2, have now been removed. (#8326) - twisted.spread.ui has been removed. (#8329) - twisted.manhole -- not to be confused with manhole in Conch -- has been removed. This includes the semi-functional Glade reactor, the manhole application, and the manhole-old twistd plugin. (#8330) - twisted.protocols.sip.DigestAuthorizer, BasicAuthorizer, and related functions have been removed.

Twisted Mail 16.3.0 (2016-07-05) ================================ No significant changes have been made for this release. Twisted Names 16.3.0 (2016-07-05) ================================= Bugfixes -------- - twisted.names.client.Resolver as well as all resolvers inheriting from twisted.names.common.ResolverBase can now understand DNS answers that come back in a different case than the query. Example: querying for www.google.com and the answer comes back with an A record for www.google.COM will now work.

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.

(#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.

Twisted Runner 16.2.0 (2016-05-18) ================================== Deprecations and Removals ------------------------- - twisted.runner.inetdtap and twisted.runner.inetdconf RPC support was deprecated as it was broken for a long time. (#8123) Twisted Web 16.2.0 (2016-05-18) =============================== Features -------- - twisted.web.http.HTTPFactory's constructor now accepts a reactor 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.

Twisted Runner 14.0.1 (2014-09-17) ================================== No significant changes have been made for this release. Twisted Web 14.0.1 (2014-09-17) =============================== Bugfixes -------- - BrowserLikePolicyForHTTPS would always ignore the specified trustRoot and use the system trust root instead, which has been rectified. (#7647) Twisted Words 14.0.1 (2014-09-17) ================================= No significant changes have been made for this release. 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.

(#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.

(#6847) - 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.

(#6751) - 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.

(#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.

(#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).

(#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.

(#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.

(#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.

(#4732) - The Twisted Web client howto now uses the correct, public name for twisted.web.client.Response. (#4769) - Some broken links were fixed, descriptions were updated, and new API links were added in the Resource Templating documentation (resource-templates.xhtml) (#4968) Other ----- - #2271, #2386, #4162, #4733, #4855, #4911, #4973 Twisted Words 11.0.0 (2011-04-01) ================================= Features -------- - twisted.words.protocols.irc.IRCClient now has an invite method. (#4820) Bugfixes -------- - twisted.words.protocols.irc.IRCClient.say is once again able to send messages when using the default value for the length limit argument. (#4758) - twisted.words.protocols.jabber.jstrports is once again able to parse jstrport description strings. (#4771) - twisted.words.protocols.msn.NotificationClient now calls the loginFailure callback when it is unable to connect to the Passport server due to missing SSL dependencies.

(#4850) Improved Documentation ---------------------- - Removed the non-working AIM bot example, depending on the obsolete twisted.words.protocols.toc functionality. (#4007) - Outdated GUI-related information was removed from the IM howto. (#4054) Deprecations and Removals ------------------------- - Remove twisted.words.protocols.toc, that was largely non-working and useless since AOL disabled TOC on their AIM network. (#4363) Other ----- - #4733, #4902 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) - 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) Deprecations and Removals ------------------------- - twisted.internet.defer.Deferred.setTimeout has been removed, after being deprecated since Twisted 2.0. (#1702) - twisted.internet.interfaces.IReactorTime.cancelCallLater (deprecated since 2007) and twisted.internet.interfaces.base.ReactorBase.cancelCallLater (deprecated since 2002) have been removed. (#4076) - Removed twisted.cred.util.py, which has been deprecated since Twisted 8.3. (#4107) - twisted.python.text.docstringLStrip was deprecated. (#4328) - The module attributes `LENGTH`, `DATA`, `COMMA`, and `NUMBER` of twisted.protocols.basic (previously used by `NetstringReceiver`) are now deprecated.

(#4546) - twisted.python.threadable.whenThreaded, deprecated since Twisted 2.2.0, has been removed. (#4550) - twisted.python.timeoutqueue, deprecated since Twisted 8.0, has been removed. (#4551) - iocpreactor transports can no longer be pickled. (#4617) Other ----- - #4300, #4475, #4477, #4504, #4556, #4562, #4564, #4569, #4608, #4616, #4617, #4626, #4630, #4650, #4705 Twisted Conch 10.2.0 (2010-11-29) ================================= Bugfixes -------- - twisted.conch.ssh.factory.SSHFactory no longer disables coredumps. (#2715) - The Deferred returned by twisted.conch.telnet.TelnetTransport.will now fires with an OptionRefused failure if the peer responds with a refusal for the option negotiation. (#4231) - SSHServerTransport and SSHClientTransport in twisted.conch.ssh.transport no longer use PyCrypto to generate random numbers for DH KEX. They also now generate values from the full valid range, rather than only half of it. (#4469) - twisted.conch.ssh.connection.SSHConnection now errbacks leftover request deferreds on connection shutdown. (#4483) Other ----- - #4677 Twisted Lore 10.2.0 (2010-11-29) ================================ No significant changes have been made for this release. Other ----- - #4571 Twisted Mail 10.2.0 (2010-11-29) ================================ Improved Documentation ---------------------- - The email server example now demonstrates how to set up authentication and authorization using twisted.cred. (#4609) Deprecations and Removals ------------------------- - twisted.mail.smtp.sendEmail, deprecated since mid 2003 (before Twisted 2.0), has been removed. (#4529) Other ----- - #4038, #4572 Twisted Names 10.2.0 (2010-11-29) ================================= Features -------- - twisted.names.server can now serve SPF resource records using twisted.names.dns.Record_SPF. twisted.names.client can query for them using lookupSenderPolicy. (#3928) Bugfixes -------- - twisted.names.common.extractRecords doesn't try to close the transport anymore in case of recursion, as it's done by the Resolver itself now. (#3998) Improved Documentation ---------------------- - Tidied up the Twisted Names documentation for easier conversion. (#4573) Twisted News 10.2.0 (2010-11-29) ================================ Bugfixes -------- - twisted.news.database.PickleStorage now invokes the email APIs correctly, allowing it to actually send moderation emails. (#4528) Twisted Pair 10.2.0 (2010-11-29) ================================ No significant changes have been made for this release. Twisted Runner 10.2.0 (2010-11-29) ================================== No significant changes have been made for this release. Twisted Web 10.2.0 (2010-11-29) =============================== Features -------- - 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) Deprecations and Removals ------------------------- - twisted.web.trp, which has been deprecated since Twisted 9.0, was removed. (#4299) Other ----- - #4576, #4577, #4709, #4723 Twisted Words 10.2.0 (2010-11-29) ================================= Features -------- - twisted.words.protocols.irc.IRCClient.msg now enforces a maximum length for messages, splitting up messages that are too long. (#4416) 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) Deprecations and Removals ------------------------- - twisted.internet.interfaces.IReactorArbitrary, twisted.application.internet.GenericServer, and twisted.application.internet.GenericClient are now deprecated. (#367) - twisted.internet.gtkreactor is now deprecated. (#2833) - twisted.trial.util.findObject has been deprecated. (#3108) - twisted.python.threadpool.ThreadSafeList is deprecated and Jython platform detection in Twisted core removed (#3725) - twisted.internet.interfaces.IUDPConnectedTransport has been removed (deprecated since Twisted 9.0).

(#4092) - twisted.application.app.reportProfile has been removed. (#4093) - twisted.application.app.getLogFile has been removed. (#4094) - Removed twisted.cred.util.py, which has been deprecated since Twisted 8.3. (#4107) - twisted.python.util.dsu is now deprecated.

(#4428) Bugfixes -------- - SSHSessionProcessProtocol now doesn't close the session when stdin is closed, but instead when both stdout and stderr are. (#4350) - 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) Deprecations and Removals ------------------------- - twisted.conch.insults.client was deprecated. (#4095) - twisted.conch.insults.colors has been deprecated. Please use twisted.conch.insults.helper instead. (#4096) - Removed twisted.conch.ssh.asn1, which has been deprecated since Twisted 9.0. (#4097) - Removed twisted.conch.ssh.common.Entropy, as Entropy.get_bytes has been deprecated since 2007 and Entropy.get_bytes was the only attribute of Entropy.
