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)
