7 What's New in Python 2.5 alpha 3?
8 =================================
10 *Release date: XX-MAY-2006*
15 - Patch #1488312, Fix memory alignment problem on SPARC in unicode
17 - Bug #1487966: Fix SystemError with conditional expression in assignment
19 - WindowsError now has two error code attributes: errno, which carries
20 the error values from errno.h, and winerror, which carries the error
21 values from winerror.h. Previous versions put the winerror.h values
22 (from GetLastError()) into the errno attribute.
24 - Patch #1475845: Raise IndentationError for unexpected indent.
26 - Patch #1479181: split open() and file() from being aliases for each other.
31 - On Win32, os.listdir now supports arbitrarily-long Unicode path names
32 (up to the system limit of 32K characters).
34 - Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
35 As a result, these functions now raise WindowsError instead of OSError.
37 - Calling Tk_Init twice is refused if the first call failed as that
43 - Patch #721464: pdb.Pdb instances can now be given explicit stdin and
44 stdout arguments, making it possible to redirect input and output
47 - Patch #1484695: Update the tarfile module to version 0.8. This fixes
48 a couple of issues, notably handling of long file names using the
49 GNU LONGNAME extension.
51 - Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
52 new flag when ``name`` is already the name of an option flag.
54 - Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
57 - Patch #1472854: make the rlcompleter.Completer class usable on non-
60 - Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
65 - Patch #1471883: Add --enable-universalsdk.
79 What's New in Python 2.5 alpha 2?
80 =================================
82 *Release date: 27-APR-2006*
87 - Bug #1465834: 'bdist_wininst preinstall script support' was fixed
88 by converting these apis from macros into exported functions again:
90 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
91 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
92 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
93 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
94 PyRun_String Py_CompileString
96 - Under COUNT_ALLOCS, types are not necessarily immortal anymore.
98 - All uses of PyStructSequence_InitType have been changed to initialize
99 the type objects only once, even if the interpreter is initialized
102 - Bug #1454485, array.array('u') could crash the interpreter. This was
103 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
104 to unicode when it didn't make sense. 'u#' now requires a unicode string.
106 - Py_UNICODE is unsigned. It was always documented as unsigned, but
107 due to a bug had a signed value in previous versions.
109 - Patch #837242: ``id()`` of any Python object always gives a positive
110 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
111 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
112 never been correct to implement a ``__hash()__`` method that returns the
113 ``id()`` of an object:
116 return id(self) # WRONG
118 because a hash result must be a (short) Python int but it was always
119 possible for ``id()`` to return a Python long. However, because ``id()``
120 could return negative values before, on a 32-bit box an ``id()`` result
121 was always usable as a hash value before this patch. That's no longer
124 - Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
125 to load extension modules and now provides the dl module. As a result,
126 sys.setdlopenflags() now works correctly on these systems. (SF patch
129 - Patch #1463867: enhanced garbage collection to allow cleanup of cycles
130 involving generators that have paused outside of any ``try`` or ``with``
131 blocks. (In 2.5a1, a paused generator that was part of a reference
132 cycle could not be garbage collected, regardless of whether it was
133 paused in a ``try`` or ``with`` block.)
138 - Patch #1191065: Fix preprocessor problems on systems where recvfrom
141 - Bug #1467952: os.listdir() now correctly raises an error if readdir()
142 fails with an error condition.
144 - Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
146 - Bug #1117761: bsddb.*open() no longer raises an exception when using
147 the cachesize parameter.
149 - Bug #1149413: bsddb.*open() no longer raises an exception when using
150 a temporary db (file=None) with the 'n' flag to truncate on open.
152 - Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
153 as older versions cause excessive test failures.
155 - Patch #1062014: AF_UNIX sockets under Linux have a special
156 abstract namespace that is now fully supported.
161 - Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
162 a doctest to be skipped (the code is not run, and the expected output
163 or exception is ignored).
165 - Fixed contextlib.nested to cope with exceptions being raised and
166 caught inside exit handlers.
168 - Updated optparse module to Optik 1.5.1 (allow numeric constants in
169 hex, octal, or binary; add ``append_const`` action; keep going if
170 gettext cannot be imported; added ``OptionParser.destroy()`` method;
171 added ``epilog`` for better help generation).
173 - Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
174 called from a thread spawned as a side effect of importing a module.
176 - The pydoc module now supports documenting packages contained in
179 - The pkgutil module now has several new utility functions, such
180 as ``walk_packages()`` to support working with packages that are either
181 in the filesystem or zip files.
183 - The mailbox module can now modify and delete messages from
184 mailboxes, in addition to simply reading them. Thanks to Gregory
185 K. Johnson for writing the code, and to the 2005 Google Summer of
186 Code for funding his work.
188 - The ``__del__`` method of class ``local`` in module ``_threading_local``
189 returned before accomplishing any of its intended cleanup.
191 - Patch #790710: Add breakpoint command lists in pdb.
193 - Patch #1063914: Add Tkinter.Misc.clipboard_get().
195 - Patch #1191700: Adjust column alignment in bdb breakpoint lists.
197 - SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
198 Windows. Bug #1469163.
200 - The warnings, linecache, inspect, traceback, site, and doctest modules
201 were updated to work correctly with modules imported from zipfiles or
202 via other PEP 302 __loader__ objects.
204 - Patch #1467770: Reduce usage of subprocess._active to processes which
205 the application hasn't waited on.
207 - Patch #1462222: Fix Tix.Grid.
209 - Fix exception when doing glob.glob('anything*/')
211 - The pstats.Stats class accepts an optional stream keyword argument to
212 direct output to an alternate file-like object.
217 - The Makefile now has a reindent target, which runs reindent.py on
220 - Patch #1470875: Building Python with MS Free Compiler
222 - Patch #1161914: Add a python-config script.
224 - Patch #1324762:Remove ccpython.cc; replace --with-cxx with
225 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
226 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
227 CXX from --with-cxx-main, see description in README.
229 - Patch #1429775: Link extension modules with the shared libpython.
231 - Fixed a libffi build problem on MIPS systems.
233 - ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
234 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
235 and "%zu" for unsigned integers of type ``size_t``.
240 - test_contextlib now checks contextlib.nested can cope with exceptions
241 being raised and caught inside exit handlers.
243 - test_cmd_line now checks operation of the -m and -c command switches
245 - The test_contextlib test in 2.5a1 wasn't actually run unless you ran
246 it separately and by hand. It also wasn't cleaning up its changes to
247 the current Decimal context.
249 - regrtest.py now has a -M option to run tests that test the new limits of
250 containers, on 64-bit architectures. Running these tests is only sensible
251 on 64-bit machines with more than two gigabytes of memory. The argument
252 passed is the maximum amount of memory for the tests to use.
257 - Added the Python benchmark suite pybench to the Tools/ directory;
258 contributed by Marc-Andre Lemburg.
263 - Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
265 - PEP 343: Added Context Types section to the library reference
266 and attempted to bring other PEP 343 related documentation into
267 line with the implementation and/or python-dev discussions.
269 - Bug #1337990: clarified that ``doctest`` does not support examples
270 requiring both expected output and an exception.
273 What's New in Python 2.5 alpha 1?
274 =================================
276 *Release date: 05-APR-2006*
281 - PEP 338: -m command line switch now delegates to runpy.run_module
282 allowing it to support modules in packages and zipfiles
284 - On Windows, .DLL is not an accepted file name extension for
285 extension modules anymore; extensions are only found if they
288 - Bug #1421664: sys.stderr.encoding is now set to the same value as
291 - __import__ accepts keyword arguments.
293 - Patch #1460496: round() now accepts keyword arguments.
295 - Fixed bug #1459029 - unicode reprs were double-escaped.
297 - Patch #1396919: The system scope threads are reenabled on FreeBSD
298 5.4 and later versions.
300 - Bug #1115379: Compiling a Unicode string with an encoding declaration
301 now gives a SyntaxError.
303 - Previously, Python code had no easy way to access the contents of a
304 cell object. Now, a ``cell_contents`` attribute has been added
305 (closes patch #1170323).
307 - Patch #1123430: Python's small-object allocator now returns an arena to
308 the system ``free()`` when all memory within an arena becomes unused
309 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
310 freed. Some applications will see a drop in virtual memory size now,
311 especially long-running applications that, from time to time, temporarily
312 use a large number of small objects. Note that when Python returns an
313 arena to the platform C's ``free()``, there's no guarantee that the
314 platform C library will in turn return that memory to the operating system.
315 The effect of the patch is to stop making that impossible, and in tests it
316 appears to be effective at least on Microsoft C and gcc-based systems.
317 Thanks to Evan Jones for hard work and patience.
319 - Patch #1434038: property() now uses the getter's docstring if there is
320 no "doc" argument given. This makes it possible to legitimately use
321 property() as a decorator to produce a read-only property.
323 - PEP 357, patch 1436368: add an __index__ method to int/long and a matching
324 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
325 of requiring an int or long in slicing and a few other contexts, enabling
326 other objects (e.g. Numeric Python's integers) to be used as slice indices.
328 - Fixed various bugs reported by Coverity's Prevent tool.
330 - PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
331 new exception base class, BaseException, which has a new message attribute.
332 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
333 Raising a string exception now raises a DeprecationWarning.
335 - Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
336 explicitly relative, using 'from .module import name' to mean 'from the same
337 package as this module is in. Imports without dots still default to the
338 old relative-then-absolute, unless 'from __future__ import
339 absolute_import' is used.
341 - Properly check if 'warnings' raises an exception (usually when a filter set
342 to "error" is triggered) when raising a warning for raising string
345 - CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
346 The name was removed from Include/code.h.
348 - PEP 308: conditional expressions were added: (x if cond else y).
351 - The copy module now "copies" function objects (as atomic objects).
352 - dict.__getitem__ now looks for a __missing__ hook before raising
355 - PEP 343: with statement implemented. Needs ``from __future__ import
356 with_statement``. Use of 'with' as a variable will generate a warning.
357 Use of 'as' as a variable will also generate a warning (unless it's
358 part of an import statement).
359 The following objects have __context__ methods:
360 - The built-in file type.
361 - The thread.LockType type.
362 - The following types defined by the threading module:
363 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
364 - The decimal.Context class.
366 - Fix the encodings package codec search function to only search
367 inside its own package. Fixes problem reported in patch #1433198.
369 Note: Codec packages should implement and register their own
370 codec search function. PEP 100 has the details.
372 - PEP 353: Using ssize_t as the index type.
374 - Patch #1400181, fix unicode string formatting to not use the locale.
375 This is how string objects work. u'%f' could use , instead of .
376 for the decimal point. Now both strings and unicode always use periods.
378 - Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
379 configure would break checking curses.h.
381 - Bug #959576: The pwd module is now builtin. This allows Python to be
382 built on UNIX platforms without $HOME set.
384 - Bug #1072182, fix some potential problems if characters are signed.
386 - Bug #889500, fix line number on SyntaxWarning for global declarations.
388 - Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
390 - Support for converting hex strings to floats no longer works.
391 This was not portable. float('0x3') now raises a ValueError.
393 - Patch #1382163: Expose Subversion revision number to Python. New C API
394 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
395 is now displayed in interactive prompt banner.
397 - Implementation of PEP 341 - Unification of try/except and try/finally.
398 "except" clauses can now be written together with a "finally" clause in
399 one try statement instead of two nested ones. Patch #1355913.
401 - Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
402 now encodes backslash correctly.
404 - Patch #1350409: Work around signal handling bug in Visual Studio 2005.
406 - Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
409 - SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
410 It was possible for dlerror() to return a NULL pointer, so
411 it will now use a default error message in this case.
413 - Replaced most Unicode charmap codecs with new ones using the
414 new Unicode translate string feature in the builtin charmap
415 codec; the codecs were created from the mapping tables available
416 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
417 encodings now include a mapping for the Apple logo)
419 - Added a few more codecs for Mac OS encodings
421 - Sped up some Unicode operations.
423 - A new AST parser implementation was completed. The abstract
424 syntax tree is available for read-only (non-compile) access
425 to Python code; an _ast module was added.
427 - SF bug #1167751: fix incorrect code being produced for generator expressions.
428 The following code now raises a SyntaxError: foo(a = i for i in range(10))
430 - SF Bug #976608: fix SystemError when mtime of an imported file is -1.
432 - SF Bug #887946: fix segfault when redirecting stdin from a directory.
433 Provide a warning when a directory is passed on the command line.
435 - Fix segfault with invalid coding.
437 - SF bug #772896: unknown encoding results in MemoryError.
439 - All iterators now have a Boolean value of True. Formerly, some iterators
440 supported a __len__() method which evaluated to False when the iterator
443 - On 64-bit platforms, when __len__() returns a value that cannot be
444 represented as a C int, raise OverflowError.
446 - test__locale is skipped on OS X < 10.4 (only partial locale support is
449 - SF bug #893549: parsing keyword arguments was broken with a few format
452 - Changes donated by Elemental Security to make it work on AIX 5.3
453 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
454 bug #105470: test_pwd fails on 64bit system (Opteron).
456 - Changes donated by Elemental Security to make it work on HP-UX 11 on
457 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
459 - Disallow keyword arguments for type constructors that don't use them
460 (fixes bug #1119418).
462 - Forward UnicodeDecodeError into SyntaxError for source encoding errors.
464 - SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
465 exceptions that cause a function to exit.
467 - The implementation of set() and frozenset() was revised to use its
468 own internal data structure. Memory consumption is reduced by 1/3
469 and there are modest speed-ups as well. The API is unchanged.
471 - SF bug #1238681: freed pointer is used in longobject.c:long_pow().
473 - SF bug #1229429: PyObject_CallMethod failed to decrement some
474 reference counts in some error exit cases.
476 - SF bug #1185883: Python's small-object memory allocator took over
477 a block managed by the platform C library whenever a realloc specified
478 a small new size. However, there's no portable way to know then how
479 much of the address space following the pointer is valid, so there's no
480 portable way to copy data from the C-managed block into Python's
481 small-object space without risking a memory fault. Python's small-object
482 realloc now leaves such blocks under the control of the platform C
485 - SF bug #1232517: An overflow error was not detected properly when
486 attempting to convert a large float to an int in os.utime().
488 - SF bug #1224347: hex longs now print with lowercase letters just
489 like their int counterparts.
491 - SF bug #1163563: the original fix for bug #1010677 ("thread Module
492 Breaks PyGILState_Ensure()") broke badly in the case of multiple
493 interpreter states; back out that fix and do a better job (see
494 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
495 for a longer write-up of the problem).
497 - SF patch #1180995: marshal now uses a binary format by default when
500 - SF patch #1181301: on platforms that appear to use IEEE 754 floats,
501 the routines that promise to produce IEEE 754 binary representations
502 of floats now simply copy bytes around.
504 - bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
507 - patch #1109424: int, long, float, complex, and unicode now check for the
508 proper magic slot for type conversions when subclassed. Previously the
509 magic slot was ignored during conversion. Semantics now match the way
510 subclasses of str always behaved. int/long/float, conversion of an instance
511 to the base class has been moved to the proper nb_* magic slot and out of
513 Thanks Walter D�rwald.
515 - Descriptors defined in C with a PyGetSetDef structure, where the setter is
516 NULL, now raise an AttributeError when attempting to set or delete the
517 attribute. Previously a TypeError was raised, but this was inconsistent
518 with the equivalent pure-Python implementation.
520 - It is now safe to call PyGILState_Release() before
521 PyEval_InitThreads() (note that if there is reason to believe there
522 are multiple threads around you still must call PyEval_InitThreads()
523 before using the Python API; this fix is for extension modules that
524 have no way of knowing if Python is multi-threaded yet).
526 - Typing Ctrl-C whilst raw_input() was waiting in a build with threads
527 disabled caused a crash.
529 - Bug #1165306: instancemethod_new allowed the creation of a method
530 with im_class == im_self == NULL, which caused a crash when called.
532 - Move exception finalisation later in the shutdown process - this
533 fixes the crash seen in bug #1165761
535 - Added two new builtins, any() and all().
537 - Defining a class with empty parentheses is now allowed
538 (e.g., ``class C(): pass`` is no longer a syntax error).
539 Patch #1176012 added support to the 'parser' module and 'compiler' package
540 (thanks to logistix for that added support).
542 - Patch #1115086: Support PY_LONGLONG in structmember.
544 - Bug #1155938: new style classes did not check that __init__() was
547 - Patch #802188: Report characters after line continuation character
548 ('\') with a specific error message.
550 - Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
552 - Bug #1124295: the __name__ attribute of file objects was
553 inadvertently made inaccessible in restricted mode.
555 - Bug #1074011: closing sys.std{out,err} now causes a flush() and
558 - min() and max() now support key= arguments with the same meaning as in
561 - The peephole optimizer now performs simple constant folding in expressions:
564 - set and frozenset objects can now be marshalled. SF #1098985.
566 - Bug #1077106: Poor argument checking could cause memory corruption
567 in calls to os.read().
569 - The parser did not complain about future statements in illegal
570 positions. It once again reports a syntax error if a future
571 statement occurs after anything other than a doc string.
573 - Change the %s format specifier for str objects so that it returns a
574 unicode instance if the argument is not an instance of basestring and
575 calling __str__ on the argument returns a unicode instance.
577 - Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
578 current thread state when the auto-GIL-state machinery knows about
579 it (since the thread state is being deleted, continuing to remember it
580 can't help, but can hurt if another thread happens to get created with
586 - Patch #1380952: fix SSL objects timing out on consecutive read()s
588 - Patch #1309579: wait3 and wait4 were added to the posix module.
590 - Patch #1231053: The audioop module now supports encoding/decoding of alaw.
591 In addition, the existing ulaw code was updated.
593 - RFE #567972: Socket objects' family, type and proto properties are
594 now exposed via new attributes.
596 - Everything under lib-old was removed. This includes the following modules:
597 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
598 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
599 util, whatsound, whrandom, zmod
601 - The following modules were removed: regsub, reconvert, regex, regex_syntax.
603 - re and sre were swapped, so help(re) provides full help. importing sre
604 is deprecated. The undocumented re.engine variable no longer exists.
606 - Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
607 SS2 (single-shift 2) escape sequences correctly.
609 - The unicodedata module was updated to the 4.1 version of the Unicode
610 database. The 3.2 version is still available as unicodedata.db_3_2_0
611 for applications that require this specific version (such as IDNA).
613 - The timing module is no longer built by default. It was deprecated
614 in PEP 4 in Python 2.0 or earlier.
616 - Patch 1433928: Added a new type, defaultdict, to the collections module.
617 This uses the new __missing__ hook behavior added to dict (see above).
619 - Bug #854823: socketmodule now builds on Sun platforms even when
620 INET_ADDRSTRLEN is not defined.
622 - Patch #1393157: os.startfile() now has an optional argument to specify
623 a "command verb" to invoke on the file.
625 - Bug #876637, prevent stack corruption when socket descriptor
626 is larger than FD_SETSIZE.
628 - Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
629 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
630 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
632 - Patch #1422385: The nis module now supports access to domains other
633 than the system default domain.
635 - Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
636 are reported, the limit on path name lengths is removed, and stat reports
637 WindowsError now (instead of OSError).
639 - Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
641 - Bug #1413192, fix seg fault in bsddb if a transaction was deleted
644 - Patch #1103116: Basic AF_NETLINK support.
646 - Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
648 - Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.

666 - Bug #1344508, Fix UNIX mmap leaking file descriptors
668 - Patch #1338314, Bug #1336623: fix tarfile so it can extract
669 REGTYPE directories from tarfiles written by old programs.
671 - Patch #1407992, fixes broken bsddb module db associate when using
672 BerkeleyDB 3.3, 4.0 or 4.1.
674 - Get bsddb module to build with BerkeleyDB version 4.4
676 - Get bsddb module to build with BerkeleyDB version 3.2
678 - Patch #1309009, Fix segfault in pyexpat when the XML document is in latin_1,
679 but Python incorrectly assumes it is in UTF-8 format
681 - Fix parse errors in the readline module when compiling without threads.
683 - Patch #1288833: Removed thread lock from socket.getaddrinfo on
684 FreeBSD 5.3 and later versions which got thread-safe getaddrinfo(3).
686 - Patches #1298449 and #1298499: Add some missing checks for error
687 returns in cStringIO.c.
689 - Patch #1297028: fix segfault if call type on MultibyteCodec,
690 MultibyteStreamReader, or MultibyteStreamWriter
692 - Fix memory leak in posix.access().
694 - Patch #1213831: Fix typo in unicodedata._getcode.
696 - Bug #1007046: os.startfile() did not accept unicode strings encoded in
697 the file system encoding.
699 - Patch #756021: Special-case socket.inet_aton('255.255.255.255') for
700 platforms that don't have inet_aton().
702 - Bug #1215928: Fix bz2.BZ2File.seek() for 64-bit file offsets.
704 - Bug #1191043: Fix bz2.BZ2File.(x)readlines for files containing one
705 line without newlines.
707 - Bug #728515: mmap.resize() now resizes the file on Unix as it did
710 - Patch #1180695: Add nanosecond stat resolution, and st_gen,
711 st_birthtime for FreeBSD.
713 - Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
714 the request code argument, which results in more C-like behaviour
715 for large or negative values.
717 - Bug #1234979: For the argument of thread.Lock.acquire, the Windows
718 implementation treated all integer values except 1 as false.
720 - Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.
722 - Patch #1212117: os.stat().st_flags is now accessible as a attribute
723 if available on the platform.
725 - Patch #1103951: Expose O_SHLOCK and O_EXLOCK in the posix module if
726 available on the platform.
728 - Bug #1166660: The readline module could segfault if hook functions
729 were set in a different thread than that which called readline.
731 - collections.deque objects now support a remove() method.
733 - operator.itemgetter() and operator.attrgetter() now support retrieving
734 multiple fields. This provides direct support for sorting on multiple
735 keys (primary, secondary, etc).
737 - os.access now supports Unicode path names on non-Win32 systems.
739 - Patches #925152, #1118602: Avoid reading after the end of the buffer
740 in pyexpat.GetInputContext.
742 - Patches #749830, #1144555: allow UNIX mmap size to default to current
745 - Added functional.partial(). See PEP309.
747 - Patch #1093585: raise a ValueError for negative history items in readline.
748 {remove_history,replace_history}
750 - The spwd module has been added, allowing access to the shadow password
753 - stat_float_times is now True.
755 - array.array objects are now picklable.
757 - the cPickle module no longer accepts the deprecated None option in the
758 args tuple returned by __reduce__().
760 - itertools.islice() now accepts None for the start and step arguments.
761 This allows islice() to work more readily with slices:
762 islice(s.start, s.stop, s.step)
764 - datetime.datetime() now has a strptime class method which can be used to
765 create datetime object using a string and format.
767 - Patch #1117961: Replace the MD5 implementation from RSA Data Security Inc
768 with the implementation from http://sourceforge.net/projects/libmd5-rfc/.
773 - PEP 338: new module runpy defines a run_module function to support
774 executing modules which provide access to source code or a code object
775 via the PEP 302 import mechanisms.
777 - The email module's parsedate_tz function now sets the daylight savings
778 flag to -1 (unknown) since it can't tell from the date whether it should
781 - Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
782 now sport attributes that provide access to the parts of the result.
784 - Patch #1462498: sgmllib now handles entity and character references
787 - Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
788 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
789 later to build this - if you have an earlier version, the C extension
790 module will not be built.
792 - Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
793 aren't officially supported here, and trying to use them will probably
794 raise an exception some day. But dicts have been allowed, and "mostly
795 worked", so support for them won't go away without warning.
797 - Bug #1445068: getpass.getpass() can now be given an explicit stream
798 argument to specify where to write the prompt.
800 - Patch #1462313, bug #1443328: the pickle modules now can handle classes
801 that have __private names in their __slots__.
803 - Bug #1250170: mimetools now handles socket.gethostname() failures gracefully.
805 - patch #1457316: "setup.py upload" now supports --identity to select the
806 key to be used for signing the uploaded code.
808 - Queue.Queue objects now support .task_done() and .join() methods
809 to make it easier to monitor when daemon threads have completed
810 processing all enqueued tasks. Patch #1455676.
812 - popen2.Popen objects now preserve the command in a .cmd attribute.
814 - Added the ctypes ffi package.
816 - email 4.0 package now integrated. This is largely the same as the email 3.0
817 package that was included in Python 2.3, except that PEP 8 module names are
818 now used (e.g. mail.message instead of email.Message). The MIME classes
819 have been moved to a subpackage (e.g. email.mime.text instead of
820 email.MIMEText). The old names are still supported for now. Several
821 deprecated Message methods have been removed and lots of bugs have been
822 fixed. More details can be found in the email package documentation.
824 - Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
825 (a subclass of tuple) that provides incremental decoders and encoders
826 (a way to use stateful codecs without the stream API). Python functions
827 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
828 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
831 - Patch #1359365: Calling next() on a closed StringIO.String object raises
832 a ValueError instead of a StopIteration now (like file and cString.String do).
833 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
834 called before (like file and StringIO.StringIO do).
836 - A regrtest option -w was added to re-run failed tests in verbose mode.
838 - Patch #1446372: quit and exit can now be called from the interactive
841 - The function get_count() has been added to the gc module, and gc.collect()
842 grew an optional 'generation' argument.
844 - A library msilib to generate Windows Installer files, and a distutils
845 command bdist_msi have been added.
847 - PEP 343: new module contextlib.py defines decorator @contextmanager
848 and helpful context managers nested() and closing().
850 - The compiler package now supports future imports after the module docstring.
852 - Bug #1413790: zipfile now sanitizes absolute archive names that are
853 not allowed by the specs.
855 - Patch #1215184: FileInput now can be given an opening hook which can
856 be used to control how files are opened.
858 - Patch #1212287: fileinput.input() now has a mode parameter for
859 specifying the file mode input files should be opened with.
861 - Patch #1215184: fileinput now has a fileno() function for getting the
864 - Patch #1349274: gettext.install() now optionally installs additional
865 translation functions other than _() in the builtin namespace.
867 - Patch #1337756: fileinput now accepts Unicode filenames.
869 - Patch #1373643: The chunk module can now read chunks larger than
872 - Patch #1417555: SimpleHTTPServer now returns Last-Modified headers.
874 - Bug #1430298: It is now possible to send a mail with an empty
875 return address using smtplib.
877 - Bug #1432260: The names of lambda functions are now properly displayed
880 - Patch #1412872: zipfile now sets the creator system to 3 (Unix)
881 unless the system is Win32.
883 - Patch #1349118: urllib now supports user:pass@ style proxy
884 specifications, raises IOErrors when proxies for unsupported protocols
885 are defined, and uses the https proxy on https redirections.
887 - Bug #902075: urllib2 now supports 'host:port' style proxy specifications.
889 - Bug #1407902: Add support for sftp:// URIs to urlparse.
891 - Bug #1371247: Update Windows locale identifiers in locale.py.
893 - Bug #1394565: SimpleHTTPServer now doesn't choke on query parameters
896 - Bug #1403410: The warnings module now doesn't get confused
897 when it can't find out the module name it generates a warning for.
899 - Patch #1177307: Added a new codec utf_8_sig for UTF-8 with a BOM signature.
901 - Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode
903 - Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
904 LoadError as documented, instead of IOError. For compatibility,
905 LoadError subclasses IOError.
907 - Added the hashlib module. It provides secure hash functions for MD5 and
908 SHA1, 224, 256, 384, and 512. Note that recent developments make the
909 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
910 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
911 Ronald L. Rivest offered this advice for Python:
913 "The consensus of researchers in this area (at least as
914 expressed at the NIST Hash Function Workshop 10/31/05),
915 is that SHA-256 is a good choice for the time being, but
916 that research should continue, and other alternatives may
917 arise from this research. The larger SHA's also seem OK."
919 - Added a subset of Fredrik Lundh's ElementTree package. Available
920 modules are xml.etree.ElementTree, xml.etree.ElementPath, and
921 xml.etree.ElementInclude, from ElementTree 1.2.6.
923 - Patch #1162825: Support non-ASCII characters in IDLE window titles.
925 - Bug #1365984: urllib now opens "data:" URLs again.
927 - Patch #1314396: prevent deadlock for threading.Thread.join() when an exception
928 is raised within the method itself on a previous call (e.g., passing in an
931 - Bug #1340337: change time.strptime() to always return ValueError when there
932 is an error in the format string.

943 socket to avoid a MemoryError on Windows.
945 - Patch #1166948: locale.py: Prefer LC_ALL, LC_CTYPE and LANG over LANGUAGE
946 to get the correct encoding.
948 - Patch #1166938: locale.py: Parse LANGUAGE as a colon separated list of
951 - Patch #1268314: Cache lines in StreamReader.readlines for performance.

955 - Bug #1167128: Fix size of a symlink in a tarfile to be 0.
957 - Patch #810023: Fix off-by-one bug in urllib.urlretrieve reporthook
960 - Bug #1163178: Make IDNA return an empty string when the input is empty.
962 - Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
963 separator and do not output trailing semicolon.
965 - Patch #1062060: urllib.urlretrieve() now raises a new exception, named
966 ContentTooShortException, when the actually downloaded size does not
967 match the Content-Length header.
969 - Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
971 - Bug #1178484: Return complete lines from codec stream readers
972 even if there is an exception in later lines, resulting in
973 correct line numbers for decoding errors in source code.
975 - Bug #1192315: Disallow negative arguments to clear() in pdb.
977 - Patch #827386: Support absolute source paths in msvccompiler.py.
979 - Patch #1105730: Apply the new implementation of commonprefix in posixpath
980 to ntpath, macpath, os2emxpath and riscospath.
982 - Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
983 __hasattr__ and __delattr__ methods on class Tk that were breaking
986 - Bug #1015140: disambiguated the term "article id" in nntplib docs and
987 docstrings to either "article number" or "message id".
989 - Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
990 parameter, but uses the usual "kwargs=None".
992 - textwrap now processes text chunks at O(n) speed instead of O(n**2).
993 Patch #1209527 (Contributed by Connelly).
995 - urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
996 to W3C name (404 -> 'Not Found'). RFE #1216944.
998 - Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
999 as this can cause problems with apps closing all file descriptors.
1001 - Bug #839151: Fix an attempt to access sys.argv in the warnings module;
1002 it can be missing in embedded interpreters
1004 - Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1006 - Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1009 - Bug #1108948: Cookie.py produced invalid JavaScript code.
1011 - The tokenize module now detects and reports indentation errors.
1014 - The tokenize module has a new untokenize() function to support a full
1015 roundtrip from lexed tokens back to Python source code. In addition,
1016 the generate_tokens() function now accepts a callable argument that
1017 terminates by raising StopIteration.
1019 - Bug #1196315: fix weakref.WeakValueDictionary constructor.
1021 - Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1022 component of the path.
1024 - Patch #1120353: The xmlrpclib module provides better, more transparent,
1025 support for datetime.{datetime,date,time} objects. With use_datetime set
1026 to True, applications shouldn't have to fiddle with the DateTime wrapper
1029 - distutils.commands.upload was added to support uploading distribution
1032 - distutils.commands.register now encodes the data as UTF-8 before posting
1035 - decimal operator and comparison methods now return NotImplemented
1036 instead of raising a TypeError when interacting with other types. This
1037 allows other classes to implement __radd__ style methods and have them
1040 - Bug #1163325: Decimal infinities failed to hash. Attempting to
1041 hash a NaN raised an InvalidOperation instead of a TypeError.
1043 - Patch #918101: Add tarfile open mode r|* for auto-detection of the
1044 stream compression; add, for symmetry reasons, r:* as a synonym of r.

1072 - Patch #1121234: Properly cleanup _exit and tkerror commands.
1074 - Patch #1049151: xdrlib now unpacks booleans as True or False.
1076 - Fixed bug in a NameError bug in cookielib. Patch #1116583.
1078 - Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1079 disables recursive traversal through instance attributes, which can
1080 be exploited in various ways.
1082 - Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
1083 flags on the HTTP listening socket.
1085 - Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1086 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1088 - Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
1089 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1091 - Bug #1110478: Revert os.environ.update to do putenv again.
1093 - Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1095 - os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1097 - Enhancements to the csv module:
1099 + Dialects are now validated by the underlying C code, better
1100 reflecting its capabilities, and improving its compliance with
1102 + Dialect parameter parsing has been re-implemented to improve error
1104 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1106 + the parser now removes the escapechar prefix from escaped characters.
1107 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
1108 types, rather than any object that can be represented as a numeric.
1109 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1111 + reader now allows \r characters to be quoted (previously it only allowed
1113 + writer doublequote handling improved.
1114 + Dialect classes passed to the module are no longer instantiated by
1115 the module before being parsed (the former validation scheme required
1116 this, but the mechanism was unreliable).
1117 + The dialect registry now contains instances of the internal
1118 C-coded dialect type, rather than references to python objects.
1119 + the internal c-coded dialect type is now immutable.
1120 + register_dialect now accepts the same keyword dialect specifications
1121 as the reader and writer, allowing the user to register dialects
1122 without first creating a dialect class.
1123 + a configurable limit to the size of parsed fields has been added -
1124 previously, an unmatched quote character could result in the entire
1125 file being read into the field buffer before an error was reported.
1126 + A new module method csv.field_size_limit() has been added that sets
1127 the parser field size limit (returning the former limit). The initial
1129 + A line_num attribute has been added to the reader object, which tracks
1130 the number of lines read from the source iterator. This is not
1131 the same as the number of records returned, as records can span
1133 + reader and writer objects were not being registered with the cyclic-GC.
1134 This has been fixed.
1136 - _DummyThread objects in the threading module now delete self.__block that is
1137 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1138 lock primitives tend to be limited in number and thus should not be wasted on
1139 a _DummyThread object. Fixes bug #1089632.
1141 - The imghdr module now detects Exif files.
1143 - StringIO.truncate() now correctly adjusts the size attribute.
1146 - locale.py now uses an updated locale alias table (built using
1147 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1148 alias file); the encoding lookup was enhanced to use Python's
1149 encoding alias table.
1151 - moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1153 - the pickle module no longer accepts the deprecated None option in the
1154 args tuple returned by __reduce__().
1156 - optparse now optionally imports gettext. This allows its use in setup.py.
1158 - the pickle module no longer uses the deprecated bin parameter.
1160 - the shelve module no longer uses the deprecated binary parameter.
1162 - the pstats module no longer uses the deprecated ignore() method.
1164 - the filecmp module no longer uses the deprecated use_statcache argument.
1166 - unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1167 extended or overridden by subclasses. Formerly, the subclassed method would
1168 be ignored by the rest of the module. (Bug #1078905).
1170 - heapq.nsmallest() and heapq.nlargest() now support key= arguments with
1171 the same meaning as in list.sort().
1173 - Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1174 once when a size argument is given. This prevents a buffer overflow in the
1175 tokenizer with very long source lines.
1177 - Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1178 immediately after creating the object, without any intervening
1179 ``.decompress()`` calls.
1181 - The reconvert.quote function can now emit triple-quoted strings. The
1182 reconvert module now has some simple documentation.
1184 - ``UserString.MutableString`` now supports negative indices in
1185 ``__setitem__`` and ``__delitem__``
1187 - Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1190 - Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1191 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1192 character even if the user has passed a size parameter to get a proper
1193 line ending. Remove the special handling of a "\r\n" that has been split
1196 - Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1197 about illegal code points. The codec now supports PEP 293 style error
1200 - Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
1201 from the input stream, so that the output is a byte string in the correct
1202 encoding instead of a unicode string.
1204 - Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1205 considering it exactly like a '*'.
1207 - Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1208 ``encodings.aliases``.
1210 - ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1212 - Patch #1413711: Certain patterns of differences were making difflib
1213 touch the recursion limit.
1215 - Bug #947906: An object oriented interface has been added to the calendar
1216 module. It's possible to generate HTML calendar now and the module can be
1217 called as a script (e.g. via ``python -mcalendar``). Localized month and
1218 weekday names can be ouput (even if an exotic encoding is used) using
1219 special classes that use unicode.
1224 - Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1225 by using -mieee gcc option.
1227 - Patch #1432345: Make python compile on DragonFly.
1229 - Build support for Win64-AMD64 was added.
1231 - Patch #1428494: Prefer linking against ncursesw over ncurses library.
1233 - Patch #881820: look for openpty and forkpty also in libbsd.
1235 - The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1236 The zlib module is now builtin on Windows.
1238 - Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1240 - Bug #1189330: configure did not correctly determine the necessary
1241 value of LINKCC if python was built with GCC 4.0.
1243 - Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1244 vulnerability in zlib 1.2.1 and 1.2.2.
1246 - EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1247 flags that change binary compatibility. Changes were also made to
1248 distutils.sysconfig to also use the environment variable when used during
1249 compilation of the interpreter and of C extensions through distutils.
1251 - SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1252 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1253 no longer exists). This configure patch makes things right.
1255 - Bug #1158607: Build with --disable-unicode again.
1257 - spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1258 defined. Discovered as a result of not being able to build on OS X.
1260 - setup.py now uses the directories specified in LDFLAGS using the -L option
1261 and in CPPFLAGS using the -I option for adding library and include
1262 directories, respectively, for compiling extension modules against. This has
1263 led to the core being compiled using the values in CPPFLAGS. It also removes
1264 the need for the special-casing of both DarwinPorts and Fink for darwin since
1265 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1266 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1267 Fink, ``-I/opt/local/include`` for DarwinPorts).
1269 - Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1270 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1271 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1272 Closes bug #1096244. Thanks Gregory Bond.
1277 - ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1278 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1279 is obtained via the ``PyObject_`` family, it must be released via the
1280 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1281 always been officially true, but when Python's small-object allocator was
1282 introduced, an attempt was made to cater to a few extension modules
1283 discovered at the time that obtained memory via ``PyObject_New`` but
1284 released it via ``PyMem_DEL``. It's years later, and if such code still
1285 exists it will fail now (probably with segfaults, but calling wrong
1286 low-level memory management functions can yield many symptoms).
1288 - Added a C API for set and frozenset objects.
1290 - Removed PyRange_New().
1292 - Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1293 mapping argument now. This string is used as a mapping table. Byte values
1294 greater than the length of the string and 0xFFFE are treated as undefined
1301 - In test_os, st_?time is now truncated before comparing it with ST_?TIME.
1303 - Patch #1276356: New resource "urlfetch" is implemented. This enables
1304 even impatient people to run tests that require remote files.
1310 - Bug #1402224: Add warning to dl docs about crashes.
1312 - Bug #1396471: Document that Windows' ftell() can return invalid
1313 values for text files with UNIX-style line endings.
1315 - Bug #1274828: Document os.path.splitunc().
1317 - Bug #1190204: Clarify which directories are searched by site.py.
1319 - Bug #1193849: Clarify os.path.expanduser() documentation.
1321 - Bug #1243192: re.UNICODE and re.LOCALE affect \d, \D, \s and \S.
1323 - Bug #755617: Document the effects of os.chown() on Windows.
1325 - Patch #1180012: The documentation for modulefinder is now in the library reference.
1327 - Patch #1213031: Document that os.chown() accepts argument values of -1.
1329 - Bug #1190563: Document os.waitpid() return value with WNOHANG flag.
1331 - Bug #1175022: Correct the example code for property().
1333 - Document the IterableUserDict class in the UserDict module.
1334 Closes bug #1166582.
1336 - Remove all latent references for "Macintosh" that referred to semantics for
1337 Mac OS 9 and change to reflect the state for OS X.
1338 Closes patch #1095802. Thanks Jack Jansen.
1347 - FreeBSD 7 support is added.
1353 - Created Misc/Vim/vim_syntax.py to auto-generate a python.vim file in that
1354 directory for syntax highlighting in Vim. Vim directory was added and placed
1355 vimrc to it (was previous up a level).
1357 - Added two new files to Tools/scripts: pysource.py, which recursively
1358 finds Python source files, and findnocoding.py, which finds Python
1359 source files that need an encoding declaration.
1360 Patch #784089, credits to Oleg Broytmann.
1362 - Bug #1072853: pindent.py used an uninitialized variable.
1364 - Patch #1177597: Correct Complex.__init__.
1366 - Fixed a display glitch in Pynche, which could cause the right arrow to
1367 wiggle over by a pixel.
