Twisted Core 10.0.0 (2010-03-01)
5
================================
9
- The twistd man page now has a SIGNALS section. (#689)
11
- reactor.spawnProcess now will not emit a PotentialZombieWarning
12
when called before reactor.run, and there will be no potential for
13
zombie processes in this case. (#2078)
15
- High-throughput applications based on Perspective Broker should now
16
run noticably faster thanks to the use of a more efficient decoding
17
function in Twisted Spread. (#2310)
19
- Documentation for trac-post-commit-hook functionality in svn-dev
22
- twisted.protocols.socks.SOCKSv4 now supports the SOCKSv4a protocol.
25
- Trial can now output test results according to the subunit
26
protocol, as long as Subunit is installed (see
27
https://launchpad.net/subunit). (#4004)
29
- twisted.protocols.amp now provides a ListOf argument type which can
30
be composed with some other argument types to create a zero or more
31
element sequence of that type. (#4116)
33
- If returnValue is invoked outside of a function decorated with
34
@inlineCallbacks, but causes a function thusly decorated to exit, a
35
DeprecationWarning will be emitted explaining this potentially
36
confusing behavior. In a future release, this will cause an
39
- twisted.python.logfile.BaseLogFile now has a reopen method allowing
40
you to use an external logrotate mechanism. (#4255)
44
- FTP.ftp_NLST now handles requests on invalid paths in a way
45
consistent with RFC 959. (#1342)
47
- twisted.python.util.initgroups now calls the low-level C initgroups
48
by default if available: the python version can create lots of I/O
49
with certain authentication setup to retrieve all the necessary
52
- startLogging now does nothing on subsequent invocations, thus
53
fixing a terrible infinite recursion bug that's only on edge case.
56
- Stringify non-string data to NetstringReceiver.sendString before
57
calculating the length so that the calculated length is equal to
58
the actual length of the transported data. (#3299)
60
- twisted.python.win32.cmdLineQuote now correctly quotes empty
61
strings arguments (#3876)
63
- Change the behavior of the Gtk2Reactor to register only one source
64
watch for each file descriptor, instead of one for reading and one
65
for writing. In particular, it fixes a bug with Glib under Windows
66
where we failed to notify when a client is connected. (#3925)
68
- Twisted Trial no longer crashes if it can't remove an old
69
_trial_temp directory. (#4020)
71
- The optional _c_urlarg extension now handles unquote("") correctly
72
on platforms where malloc(0) returns NULL, such as AIX. It also
73
compiles with less warnings. (#4142)
75
- On POSIX, child processes created with reactor.spawnProcess will no
76
longer automatically ignore the signals which the parent process
77
has set to be ignored. (#4199)
79
- All SOCKSv4a tests now use a dummy reactor with a deterministic
80
resolve method. (#4275)
82
- Prevent extraneous server, date and content-type headers in proxy
85

symlink cycle detection (#3911)
179

570
Twisted 2.5.0 is a major feature release, with several interesting new
571
developments and a great number of bug fixes. Some of the highlights
574
* AMP, the Asynchronous Messaging Protocol, was introduced. AMP is
575
a protocol which provides request/response semantics over a
576
persistent connection in a very simple and extensible manner.
578
* An Epoll-based reactor was added, which can be used with twistd or
579
trial by passing "-r epoll" on the command line. This may improve
580
performance of certain high-traffic network applications.
582
* The 'twistd' command can now accept sub-commands which name an
583
application to run. For example, 'twistd web --path .' will start a
584
web server serving files out of the current directory. This
585
functionality is meant to replace the old way of doing things with
586
'mktap' and 'twistd -f'.
588
* Python 2.5 is now supported. Previous releases of Twisted were
589
broken by changes in the release of Python 2.5.
591
* 'inlineCallbacks' was added, which allows taking advantage of the
592
new 'yield' expression syntax in Python 2.5 to avoid writing
593
callbacks for Deferreds.
595
In addition to these changes, there are many other minor features and
596
a large number of bug fixes.

618
can be selected (#719)

686
- Misc: #1717, #1705, #1563, #1719, #1721, #1722, #1728.
694
- twisted-dev-mode's F9 now uses trial's --testmodule feature, rather than
695
trying to guess what tests to run. This will break files using the "-x"
696
test-case-name hack (just use a comma separated list instead).
697
- API Documentation improvements.
698
- A new Producer/Consumer guide (#53)
699
- Better-defined error behavior in IReactorMulticast (#1578)
700

713
- twisted.python.filepath.FilePath.__repr__ is safer.
714
- Fix trial's "until-failure" mode. (#1453)
715

716
results) to propagate to the resulting Deferred (#1709).
717
- Misc: #1483, #1495, #1503, #1532, #1539, #1559, #1509, #1538,

725
- Removal of already-deprecated trial APIs: the assertions module,
726

727
util.spinUntil, util.spinWhile, util.extract_tb,

util.format_exception, util.suppress_warnings, unittest.wait,
730
- The backwards compatibility layer of twisted.python.components
731
(e.g., backwardsCompatImplements, fixClassImplements, etc) has been
732
disabled. The functions still exist, but do nothing as to not break
733
user code outright (#1511)
734
- Deprecate the usage of the 'default' argument as a keyword argument
735
in Interface.__call__. Passing a second positional argument to
736
specify the default return value of the adaptation is still
745
- Twisted no longer works with Python 2.2
746
- FTP server supports more clients
747
- Process support on Windows

- Continued Trial refactoring
751
- Default trial reporter is verbose black&white when color isn't supported
752
- Deferreds returned in trial tests that don't fire before the
753
unittest timeout now have their errback fired with a TimeoutError
754
- raising SkipTest in setUp and setUpClass skips tests
755
- Test suites are failed if there are import errors
761
- Fixed infinite loops in datagramReceived edge cases
762

771
- spinWhile and spinUntil
773

784
integration with foreign event loops much simpler.
785
- major improvements to twisted.conch.insults, including many new widgets.
786
- adbapi ConnectionPools now have 'runWithConnection' which is
787
similar to runInteraction but gives you a connection object instead of
789
- __file__ is now usable in tac files
790
- twisted.cred.pamauth now contains a PAM checker (moved from twisted.conch)
791
- twisted.protocols.policies.LimitTotalConnectionsFactory now exists,
792
which does as the name suggests
793
- twisted.protocols.ident now uses /proc/net/tcp on Linux [233]
794
- trial now recurses packages by default (a la the old -R parameter)
795
- (PB) Calling a remote method that doesn't exist now raises
796
NoSuchMethod instead of AttributeError.
800
- FTP client and server improvements
801
- Trial improvements: The code is now much simpler, and more stable.
802
- twisted.protocols.basic.FileSender now works with empty files
803
- Twisted should now be much more usable on Pythons without thread support.
804
- minor improvements to process code in win32eventreactor
805
- twistd -y (--python) now implies -o (--nosave). [539]
806
- improved lockfile handling especially with respect to unix sockets.
807
- deferredGenerator now no longer overuses the stack, which sometimes
808
caused stack overflows.
809
- Failure.raiseException now at least always raises the correct Exception.
810
- minor improvements to serialport code
814
- twisted.python.componts.getAdapter. Use IFoo(o) instead.
815
- Adapter persistence (IFoo(x, persist=True)). Just don't use it.
816
- log.debug. It was equivalent to log.msg(), just use that.
817
- twisted.protocols.telnet. twisted.conch.telnet replaces it.
818
- Setting a trial reporter using a flag to 'trial'. Instead of 'trial
819
--bwverbose', for example, use 'trial --reporter=bwverbose'.
820
- trial --coverage will become a flag in Twisted 2.2.
821
- passing a fully-qualified python name to --reporter is
822
deprecated. Pass only names of Reporter plugins.
824
- trial -R (--recurse) is now the default, so passing it is deprecated.
825
- trial --reporter-args. Use the plugin system to do this sort of thing.
826
- trial.assertions.assertionMethod and trial.unittest.assertionMethod
827
are both deprecated. Use instance methods on TestCases instead.
828
- trial's deferredResult, deferredError, and wait functions. Return
829
Deferreds from your test methods instead of using them.
830
- Raising unittest.SkipTest with no arguments. Give a reason for your skip.
831
- The Failure returned from a gatherResults and DeferredList is now
832
of type FirstError instead of a tuple of (Exception, index). It
833
supports a firstError[idx] syntax but that is deprecated. Use
834
firstError.subFailure and firstError.index instead.
835
- whenThreaded now simply calls the passed function synchronously.
839
Minor bug fix release.
