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 Core 16.4.0 (2016-08-25)

================================

Features

--------

- Add twisted.application.twist, meant to eventually replace twistd

with a simpler interface. Add twisted.application.runner API,

currently private, which twist is built on. (#5705)

- The new interface IHandshakeListener that can be implemented by any

Protocol provides a callback that is called when the TLS handshake

has been completed, allowing Protocols to make decisions about the

TLS configuration before application data is sent. (#6024)

- twisted.python.syslog has been ported to Python 3. (#7957)

- twisted.internet.defer.ensureDeferred has been added, similar to

asyncio's ensure_future. Wrapping a coroutine (the result of a

function defined using async def, available only on Python 3.5+)

with it allows you to use the "await" keyword with Deferreds inside

the coroutine, similar to "yield" when using inlineCallbacks.

(#8088)

- twisted.internet.inotify have been ported to Python 3 (#8211)

- twisted.enterprise has been ported to Python 3. The third-party

pysqlite2 package has not been ported to Python 3, so any database

connector based on pysqlite2 cannot be used. Instead the sqlite3

module included with Python 3 should be used. (#8303)

- Scripts such as cftp, ckeygen, conch, mailmail, pyhtmlizer,

tkconch, twistd and trial have been updated to be setuptools

console scripts. (#8491)

- twisted.pair.raw and twisted.pair.rawudp have been ported to Python

3 (#8545)

- twisted.internet.baseprocess has been ported to Python 3. (#8546)

- twisted.python.dist has been ported to Python 3 (#8556)

- twisted.internet.interfaces.IOpenSSLContextFactory has been added,

which defines the interface provided both by the old-style

twisted.internet.ssl.ContextFactory class and the newer

twisted.interface.ssl.CertificateOptions class. This is a precursor

to formally deprecating the former class in favour of the latter.

(#8597)

- twisted.python.zipstream has been ported to Python 3 (#8607)

- Zip file entries returned by ChunkingZipFile.readfile() are now

context managers. (#8641)

- twisted.protocols.socks has been ported to Python 3 (#8665)

- twisted.spread.banana has been ported to Python 3 (#8667)

- Trial can now be invoked via "python -m twisted.trial". (#8712)

- twisted.protocols.postfix has been ported to Python 3 (#8713)

- twisted.protocols.wire and twisted.protocols.portforwarding have

been ported to Python 3 (#8717)

- twisted.protocols.stateful has been ported to Python 3 (#8718)

- twisted.protocols.memcache is now compatible with Python 3. (#8726)

- twisted.protocols.dict has been ported to Python 3 (#8732)

Bugfixes

--------

- pip install -e ".[dev]" now works on Python 3, but it will not

install twistedchecker or pydoctor, which have not yet been ported.

(#7807)

- twistd can now properly daemonize on Linux/Unix when run under

Python3 and will not hang indefinitely. (#8155)

- tox can now be used to run Twisted's tests on Windows (#8578)

- twisted.python.filepath.setContent() and

twisted.python.filepath.moveTo() now work on Windows with Python 3

(#8610)

- twisted.internet.win32eventreactor works on Python 3 in Windows

(#8626)

- The TLS payload buffer size was reduced in

twisted.protocols.tls.TLSMemoryBIOProtocol. This fixes writing of

very long strings using the TLSv1_1 method from the OpenSSL

library. (#8693)

- twisted.logger._flatten.flattenEvent() now does not crash if passed

a unicode string. (#8699)

- twisted.application.strports.service (and thus twistd) no longer

swallow asynchronous exceptions from IStreamServerEndpoint.listen.

(#8710)

- _twistd_unix now reports the name and encoded message of an

exception raised during daemonization on Python 2 and 3. (#8731)

- twisted.protocols.amp now handles floats on Python 3. Previously,

sending a float would raise a ValueError. (#8746)

Improved Documentation

----------------------

- Some broken links to xprogramming in the unit test documentation

have been fixed. (#8579)

- The Twisted Tutorial "The Evolution of Finger" has been updated to

use endpoints throughout. (#8588)

- Updated the mail examples to use endpoints and better TLS. (#8595)

- Changed the Twisted Web howto to use endpoints and modern TLS.

(#8596)

- Updated bug report URL in man pages. (#8600)

- In twisted.internet.udp.Port, write() takes a parameter of type

bytes. This is clarified in the docstring. (#8635)

- twisted.internet.interfaces.ITransport.write() and

twisted.internet.interfaces.ITransport.writeSequence() take bytes

parameters. (#8636)

- twisted.python.filepath.AbstractFilePath.getContent() returns

bytes. The docstring was updated to clarify this. (#8637)

- Updated release notes to reflect that 15.4 is the last version that

supported Python 2.6, not 15.5. (#8651)

- A missing space in defer.rst resulted in badly rendered output. The

space was added. (#8723)

Deprecations and Removals

-------------------------

- Dropped support for pyOpenSSL versions less than 16.0.0. (#8441)

Features

--------

- twisted.runner has been ported to Python 3. (#8739)

Twisted Web 16.4.0 (2016-08-25)

===============================

Features

--------

- Twisted web HTTP/2 servers now time out HTTP/2 connections in the

same manner as HTTP/1.1 connections. (#8480)

Bugfixes

--------

- A bug in twisted.web.server.Site.makeSession which may lead to

predictable session IDs was fixed. Session IDs are now generated

securely using `os.urandom`. (#3460)

- twisted.web.server.Request.getSession will now, for a request sent

over HTTPS, set a "Secure" cookie, preventing the secure session

from being sent over plain-text HTTP. (#3461)

- If called multiple times, twisted.web.http.Request.setLastModified

now correctly observes the greatest supplied value. (#3807)

- The HTTP server now correctly times connections out. (broken in

16.2) (#8481)

- Twisted's HTTP/2 support no longer throws priority exceptions when

WINDOW_UDPATE frames are received after a response has been

completed. (#8558)

- twisted.web.twcgi.CGIScript will now not pass the "Proxy" header to

CGI scripts, as a mitigation to CVE-2016-1000111. (#8623)

- Twisted Web's HTTP/2 server can now tolerate streams being reset by

the client midway through a data upload without throwing

exceptions. (#8682)

- twisted.web.http.Request now swallows header writes on reset HTTP/2

streams, rather than erroring out. (#8685)

- twisted.web's HTTP/2 server now tolerates receiving WINDOW_UPDATE

frames for streams for which it has no outstanding data to send.

(#8695)

- twisted.web.http.HTTPChannel now resumes producing on finished,

non-persistent connections. This prevents HTTP/1 servers using TLS

from leaking a CLOSE_WAIT socket per request. (#8766)

- twisted.words.protocols.irc.ERR_TOOMANYMATCHES was introduced

according to the RFC 2812 errata. (#8585)

Bugfixes

--------

- twisted.words.protocols.irc.RPL_ADMINLOC was removed and replaced

with twisted.words.protocols.irc.RPL_ADMINLOC1 and

twisted.words.protocols.irc.RPL_ADMINLOC2 to match the admin

commands defined in RFC 2812. (#8585)

- twisted.words.protocols.jabber.sasl_mechanisms has been fixed for

Python 3.3 (#8738)

Improved Documentation

Other

-----

- #8360, #8460

Twisted Core 16.3.0 (2016-07-05)

================================

Features

--------

- Defined a new interface, IProtocolNegotiationFactory, that can be

implemented by IOpenSSLClientConnectionCreator or

IOpenSSLServerConnectionCreator factories to allow them to offer

protocols for negotiation using ALPN or NPN during the TLS

handshake. (#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. (#8445)

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. (#8343)

==================================

No significant changes have been made for this release.

Twisted Web 16.3.0 (2016-07-05)

===============================

Features

--------

- twisted.web.http.HTTPChannel now implements ITransport. Along with

this change, twisted.web.http.Request now directs all its writes to

the HTTPChannel, rather than to the backing transport. This change

is required for future HTTP/2 work. (#8191)

- twisted.web.http.HTTPChannel now has a HTTP/2 implementation which

will be used if the transport has negotiated using it through

ALPN/NPN (see #8188). (#8194)

Bugfixes

--------

- twisted.web.client.Agent and twisted.web.client.ProxyAgent now add

brackets to IPv6 literal addresses in the host header they send.

(#8369)

- The HTTP server now correctly times connections out. (broken in

16.2) (#8481)

Deprecations and Removals

-------------------------

- twisted.web would previously dispatch pipelined requests

simultaneously and queue the responses. This behaviour did not

enforce any of the guarantees required by RFC 7230 or make it

possible for users to enforce those requirements. For this reason,

the parallel dispatch of requests has been removed. Pipelined

requests are now processed serially. (#8320)

Twisted Words 16.3.0 (2016-07-05)

=================================

No significant changes have been made for this release.

Twisted Core 16.2.0 (2016-05-18)

================================

Features

--------

- twisted.protocols.haproxy.proxyEndpoint provides an endpoint that

wraps any other stream server endpoint with the PROXY protocol that

retains information about the original client connection handled by

the proxy; this wrapper is also exposed via the string description

prefix 'haproxy'; for example 'twistd web --port haproxy:tcp:8765'.

(#8203)

- twisted.application.app.AppLogger (used by twistd) now uses the new

logging system. (#8235)

Bugfixes

--------

- twisted.application-using applications (trial, twistd, etc) now

work with the --reactor option on Python 3. (#8299)

- Failures are now logged by STDLibLogObserver. (#8316)

Improved Documentation

----------------------

- Deprecation documentation was extended to include a quick check

list for developers. (#5645)

- The Twisted Deprecation Policy is now documented in the Twisted

Development Policy. (#8082)

- The documentation examples for UDP now work on Python 3. (#8280)

Deprecations and Removals

-------------------------

- Passing a factory that produces log observers that do not implement

twisted.logger.ILogObserver or twisted.python.log.ILogObserver to

twisted.application.app.AppLogger has been deprecated. This is

primarily used by twistd's --logger option. Please use factories

that produce log observers implementing twisted.logger.ILogObserver

or the legacy twisted.python.log.ILogObserver. (#8235)

- twisted.internet.qtreactor, a stub that imported the external

qtreactor, has been removed. (#8288)

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. (#8318)

with an AlreadyCalledError when the Deferred it returns is

cancelled after all outgoing connection attempts have been made but

none have yet succeeded or failed. (#8014)

- twisted.internet.task.LoopingCall.withCount when run with internal

of 0, now calls the countCallable with 1, regardless of the time

passed between calls. (#8125)

- twisted.internet.endpoints.serverFromString, when parsing a SSL

strports definition, now gives the correct error message when an

empty chain file is given. (#8222)

Improved Documentation

----------------------

- The Twisted Project has adopted the Contributor Covenant as its

Code of Conduct. (#8173)

Bugfixes

--------

- twisted.conch.ssh.channel.SSHChannel's getPeer and getHost methods

now return an object which provides IAddress instead of an old-

style tuple address. (#5999)

Twisted Web 16.0.0 (2016-03-10)

===============================

Features

--------

- twisted.web.http_headers._DictHeaders now correctly handles

updating via keyword arguments in Python 3 (therefore

twisted.web.http_headers is now fully ported to Python 3). (#6082)

- twisted.web.wsgi has been ported to Python 3. (#7993)

- twisted.web.http_headers.Headers now accepts both Unicode and

bytestring keys and values, encoding to iso-8859-1 and utf8

respectively. (#8129)

- twisted.web.vhost ported to Python 3. (#8132)

Bugfixes

--------

- twisted.web.http.HTTPChannel now correctly handles non-ascii method

name by returning 400. Previously non-ascii method name was causing

unhandled exceptions. (#8102)

- twisted.web.static.File on Python 3 now redirects paths to

directories without a trailing slash, to a path with a trailing

slash, as on Python 2. (#8169)

Deprecations and Removals

-------------------------

- twisted.web.http.Request's headers and request_headers attributes,

deprecated since Twisted 13.2, have been removed. (#8136)

Twisted Core 15.5.0 (2015-11-28)

================================

Python 3.5 (on POSIX) support has been added.

This release introduces changes that are required for Conch's SSH

implementation to work with OpenSSH 6.9+ servers.

Features

--------

- twisted.python.url is a new abstraction for URLs, supporting RFC

3987 IRIs. (#5388)

- twisted.python.logfile is now ported to Python 3. (#6749)

- twisted.python.zippath has been ported to Python 3. (#6917)

- twisted.internet.ssl.CertificateOptions and

twisted.internet.ssl.optionsForClientTLS now take a

acceptableProtocols parameter that enables negotiation of the next

protocol to speak after the TLS handshake has completed. This field

advertises protocols over both NPN and ALPN. Also added new

INegotiated interface for TLS interfaces that support protocol

negotiation. This interface adds a negotiatedProtocol property that

reports what protocol, if any, was negotiated in the TLS handshake.

(#7860)

- twisted.python.urlpath.URLPath now operates correctly on Python 3,

using bytes instead of strings, and introduces the fromBytes

constructor to assist with creating them cross-version. (#7994)

- twisted.application.strports is now ported to Python 3. (#8011)

- twistd (the Twisted Daemon) is now ported to Python 3. (#8012)

- Python 3.5 is now supported on POSIX platforms. (#8042)

- twisted.internet.serialport is now ported on Python 3. (#8099)

Bugfixes

--------

- twisted.logger.formatEvent now can format an event if it was

flattened (twisted.logger.eventAsJSON does this) and has text after

the last replacement field. (#8003)

- twisted.cred.checkers.FilePasswordDB now logs an error if the

credentials db file does not exist, no longer raises an unhandled

error. (#8028)

- twisted.python.threadpool.ThreadPool now properly starts enough

threads to do any work scheduled before ThreadPool.start() is

called, such as when work is scheduled in the reactor via

reactor.callInThread() before reactor.run(). (#8090)

Improved Documentation

----------------------

- Twisted Development test standard documentation now contain

information about avoiding test data files. (#6535)

- The documentation for twisted.internet.defer.DeferredSemaphore now

describes the actual usage for limit and tokens instance

attributes. (#8024)

Deprecations and Removals

-------------------------

stdlib support is now always used instead. (#5861)

- Python 2.6 is no longer supported. (#8017)

- twisted.python.util.OrderedDict is now deprecated, and uses of it

in Twisted are replaced with collections.OrderedDict. (#8051)

- twisted.persisted.sob.load, twisted.persisted.sob.loadValueFromFile

and twisted.persisted.sob.Persistent.save() are now deprecated when

used with a passphrase. The encyption used by these methods are

weak. (#8081)

- twisted.internet.interfaces.IStreamClientEndpointStringParser has

been removed and Twisted will no longer use parsers implementing

this interface. (#8094)
