Neal Norwitz7a5fc282006-05-15 06:48:14 +000010*Release date: XX-MAY-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Tim Petersb713ec22006-05-23 18:45:30 +000015- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
16 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
17 an integer close to ``sys.maxint``. This was repaired by patch
18 #1335972, which also gives a nice speedup.
19
Richard Jonescebbefc2006-05-23 18:28:17 +000020- Patch #1337051: reduced size of frame objects.
21
22- PyErr_NewException now accepts a tuple of base classes as its
23 "base" parameter.
24
Richard Jones7c88dcc2006-05-23 10:37:38 +000025- Patch #876206: function call speedup by retaining allocated frame
26 objects.
27
Georg Brandl7b90e162006-05-18 07:01:27 +000028- Bug #1462152: file() now checks more thoroughly for invalid mode
29 strings and removes a possible "U" before passing the mode to the
30 C library function.
31
Neal Norwitz1004a532006-05-15 07:17:23 +000032- Patch #1488312, Fix memory alignment problem on SPARC in unicode
33
Neal Norwitz373f0a72006-05-15 07:04:36 +000034- Bug #1487966: Fix SystemError with conditional expression in assignment
35
Martin v. Löwis879768d2006-05-11 13:28:43 +000036- WindowsError now has two error code attributes: errno, which carries
37 the error values from errno.h, and winerror, which carries the error
38 values from winerror.h. Previous versions put the winerror.h values
39 (from GetLastError()) into the errno attribute.
40
Martin v. Löwis77736712006-05-04 05:51:03 +000041- Patch #1475845: Raise IndentationError for unexpected indent.
42
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000043- Patch #1479181: split open() and file() from being aliases for each other.
44
Neal Norwitz7a5fc282006-05-15 06:48:14 +000045Extension Modules
46-----------------
47
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000048- Patch #1493701: performance enhancements for struct module.
49
Georg Brandl378d5922006-05-17 14:26:50 +000050- Patch #1490224: time.altzone is now set correctly on Cygwin.
51
Georg Brandl8d3342b2006-05-16 07:38:27 +000052- Patch #1435422: zlib's compress and decompress objects now have a
53 copy() method.
54
Neal Norwitz7a5fc282006-05-15 06:48:14 +000055- On Win32, os.listdir now supports arbitrarily-long Unicode path names
56 (up to the system limit of 32K characters).
57
58- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
59 As a result, these functions now raise WindowsError instead of OSError.
60
61- Calling Tk_Init twice is refused if the first call failed as that
62 may deadlock.
63
64Library
65-------
66
Bob Ippolito7298f272006-05-23 18:43:47 +000067- Patch #1281707: speed up gzip.readline.

75
Georg Brandl49c8f4c2006-05-15 19:30:35 +000076- Patch #1488881: add support for external file objects in bz2 compressed
77 tarfiles.
78
Neal Norwitz7a5fc282006-05-15 06:48:14 +000079- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
80 stdout arguments, making it possible to redirect input and output
81 for remote debugging.
82
83- Patch #1484695: Update the tarfile module to version 0.8. This fixes
84 a couple of issues, notably handling of long file names using the
85 GNU LONGNAME extension.
86
87- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
88 new flag when ``name`` is already the name of an option flag.
89
90- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
91 package.
92
93- Patch #1472854: make the rlcompleter.Completer class usable on non-
94 UNIX platforms.

119What's New in Python 2.5 alpha 2?
120=================================
121
122*Release date: 27-APR-2006*
123
124Core and builtins
125-----------------
126
Thomas Heller1b046642006-04-18 18:51:06 +0000127- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
128 by converting these apis from macros into exported functions again:
129
130 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
131 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
132 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
133 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
134 PyRun_String Py_CompileString
135
Martin v. Löwis45294a92006-04-18 06:24:08 +0000136- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
137
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000138- All uses of PyStructSequence_InitType have been changed to initialize
139 the type objects only once, even if the interpreter is initialized
140 multiple times.
141
Neal Norwitz61546162006-04-14 05:20:28 +0000142- Bug #1454485, array.array('u') could crash the interpreter. This was
143 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
144 to unicode when it didn't make sense. 'u#' now requires a unicode string.
145
146- Py_UNICODE is unsigned. It was always documented as unsigned, but
147 due to a bug had a signed value in previous versions.
148
Tim Peters3a5e8b12006-04-11 01:44:07 +0000149- Patch #837242: ``id()`` of any Python object always gives a positive
150 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
151 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000152 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000153 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000154
Tim Peters3a5e8b12006-04-11 01:44:07 +0000155 def __hash__(self):
156 return id(self) # WRONG
157
158 because a hash result must be a (short) Python int but it was always
159 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000160 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000161 was always usable as a hash value before this patch. That's no longer
162 necessarily so.
163
164- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000165 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000166 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000167 #1454844)
168
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000169- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
170 involving generators that have paused outside of any ``try`` or ``with``
171 blocks. (In 2.5a1, a paused generator that was part of a reference
172 cycle could not be garbage collected, regardless of whether it was
173 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000174
Anthony Baxter51bcb682006-04-05 14:51:42 +0000175Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000178- Patch #1191065: Fix preprocessor problems on systems where recvfrom
179 is a macro.
180
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000181- Bug #1467952: os.listdir() now correctly raises an error if readdir()
182 fails with an error condition.
183
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000184- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
185
186- Bug #1117761: bsddb.*open() no longer raises an exception when using
187 the cachesize parameter.
188
189- Bug #1149413: bsddb.*open() no longer raises an exception when using
190 a temporary db (file=None) with the 'n' flag to truncate on open.
191
192- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
193 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000194
Armin Rigoa9017c32006-04-19 11:50:27 +0000195- Patch #1062014: AF_UNIX sockets under Linux have a special
196 abstract namespace that is now fully supported.
197
Anthony Baxter51bcb682006-04-05 14:51:42 +0000198Library
199-------
200
Tim Peters711bf302006-04-25 03:31:36 +0000201- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
202 a doctest to be skipped (the code is not run, and the expected output
203 or exception is ignored).
204
Nick Coghlanda2268f2006-04-24 04:37:15 +0000205- Fixed contextlib.nested to cope with exceptions being raised and
206 caught inside exit handlers.
207
Greg Wardab05edc2006-04-23 03:47:58 +0000208- Updated optparse module to Optik 1.5.1 (allow numeric constants in
209 hex, octal, or binary; add ``append_const`` action; keep going if
210 gettext cannot be imported; added ``OptionParser.destroy()`` method;
211 added ``epilog`` for better help generation).
212
Tim Peters21fbd572006-04-21 21:18:10 +0000213- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
214 called from a thread spawned as a side effect of importing a module.
215
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000216- The pydoc module now supports documenting packages contained in
217 .zip or .egg files.
218
219- The pkgutil module now has several new utility functions, such
220 as ``walk_packages()`` to support working with packages that are either
221 in the filesystem or zip files.
222
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000223- The mailbox module can now modify and delete messages from
224 mailboxes, in addition to simply reading them. Thanks to Gregory
225 K. Johnson for writing the code, and to the 2005 Google Summer of
226 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000227
Tim Petersc7605f22006-04-17 21:12:33 +0000228- The ``__del__`` method of class ``local`` in module ``_threading_local``
229 returned before accomplishing any of its intended cleanup.

236
Anthony Baxtere29002c2006-04-12 12:07:31 +0000237- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
238 Windows. Bug #1469163.
239
Phillip J. Eby47032112006-04-11 01:07:43 +0000240- The warnings, linecache, inspect, traceback, site, and doctest modules
241 were updated to work correctly with modules imported from zipfiles or
242 via other PEP 302 __loader__ objects.
243
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000244- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000264- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
265 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000266 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000267 CXX from --with-cxx-main, see description in README.
268

284
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000285- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
286 it separately and by hand. It also wasn't cleaning up its changes to
287 the current Decimal context.
288
Thomas Woutersabd08882006-04-26 15:53:30 +0000289- regrtest.py now has a -M option to run tests that test the new limits of
290 containers, on 64-bit architectures. Running these tests is only sensible
291 on 64-bit machines with more than two gigabytes of memory. The argument
292 passed is the maximum amount of memory for the tests to use.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000316*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000317

320
Nick Coghlan43832302006-04-23 17:04:07 +0000321- PEP 338: -m command line switch now delegates to runpy.run_module
322 allowing it to support modules in packages and zipfiles
323
Martin v. Löwisc661b882006-04-20 04:54:23 +0000324- On Windows, .DLL is not an accepted file name extension for
325 extension modules anymore; extensions are only found if they
326 end in .PYD.
327
Martin v. Löwisea62d252006-04-03 10:56:49 +0000328- Bug #1421664: sys.stderr.encoding is now set to the same value as
329 sys.stdout.encoding.

Hye-Shik Changd478f342006-03-23 12:32:36 +0000337- Patch #1396919: The system scope threads are reenabled on FreeBSD
338 5.4 and later versions.
339
Neal Norwitze98ccf62006-03-23 05:39:47 +0000340- Bug #1115379: Compiling a Unicode string with an encoding declaration
341 now gives a SyntaxError.
342
Georg Brandlabd1ff82006-03-18 07:59:59 +0000343- Previously, Python code had no easy way to access the contents of a
344 cell object. Now, a ``cell_contents`` attribute has been added
345 (closes patch #1170323).
346
Tim Peterscf79aac2006-03-16 01:14:46 +0000347- Patch #1123430: Python's small-object allocator now returns an arena to
348 the system ``free()`` when all memory within an arena becomes unused
349 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
350 freed. Some applications will see a drop in virtual memory size now,
351 especially long-running applications that, from time to time, temporarily
352 use a large number of small objects. Note that when Python returns an
353 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000354 platform C library will in turn return that memory to the operating system.
355 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000356 appears to be effective at least on Microsoft C and gcc-based systems.
357 Thanks to Evan Jones for hard work and patience.
358
Georg Brandl533ff6f2006-03-08 18:09:27 +0000359- Patch #1434038: property() now uses the getter's docstring if there is
360 no "doc" argument given. This makes it possible to legitimately use
361 property() as a decorator to produce a read-only property.
362
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000363- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
364 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
365 of requiring an int or long in slicing and a few other contexts, enabling
366 other objects (e.g. Numeric Python's integers) to be used as slice indices.
367
Neal Norwitz995acdf2006-03-07 05:01:00 +0000368- Fixed various bugs reported by Coverity's Prevent tool.
369
Brett Cannonbf364092006-03-01 04:25:17 +0000370- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
371 new exception base class, BaseException, which has a new message attribute.
372 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
373 Raising a string exception now raises a DeprecationWarning.
374
Thomas Woutersfb609f42006-02-28 16:37:25 +0000375- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
376 explicitly relative, using 'from .module import name' to mean 'from the same
377 package as this module is in. Imports without dots still default to the
378 old relative-then-absolute, unless 'from __future__ import
379 absolute_import' is used.
380
Brett Cannona7446e32006-02-27 23:39:10 +0000381- Properly check if 'warnings' raises an exception (usually when a filter set
382 to "error" is triggered) when raising a warning for raising string
383 exceptions.
384
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000385- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000386 The name was removed from Include/code.h.
387
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000388- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000389
Guido van Rossum1968ad32006-02-25 22:38:04 +0000390- Patch 1433928:
391 - The copy module now "copies" function objects (as atomic objects).
392 - dict.__getitem__ now looks for a __missing__ hook before raising
393 KeyError.
394
Tim Peters84ef21c2006-02-28 20:39:06 +0000395- PEP 343: with statement implemented. Needs ``from __future__ import
396 with_statement``. Use of 'with' as a variable will generate a warning.
397 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000398 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000399 The following objects have __context__ methods:
400 - The built-in file type.
401 - The thread.LockType type.
402 - The following types defined by the threading module:
403 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
404 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000405
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000406- Fix the encodings package codec search function to only search
407 inside its own package. Fixes problem reported in patch #1433198.
408
409 Note: Codec packages should implement and register their own
410 codec search function. PEP 100 has the details.
411
Martin v. Löwis18e16552006-02-15 17:27:45 +0000412- PEP 353: Using ssize_t as the index type.
413
Neal Norwitzfc76d632006-01-10 06:03:13 +0000414- Patch #1400181, fix unicode string formatting to not use the locale.
415 This is how string objects work. u'%f' could use , instead of .
416 for the decimal point. Now both strings and unicode always use periods.
417
Neal Norwitz671b9e32006-01-09 07:07:12 +0000418- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
419 configure would break checking curses.h.
420
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000421- Bug #959576: The pwd module is now builtin. This allows Python to be
422 built on UNIX platforms without $HOME set.
423
Neal Norwitzc10978f2005-12-19 06:07:16 +0000424- Bug #1072182, fix some potential problems if characters are signed.
425
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000426- Bug #889500, fix line number on SyntaxWarning for global declarations.
427
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000428- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
429
Neal Norwitze7214a12005-12-18 05:03:17 +0000430- Support for converting hex strings to floats no longer works.
431 This was not portable. float('0x3') now raises a ValueError.
432
Barry Warsaw2a38a862005-12-18 01:27:35 +0000433- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000434 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000435 is now displayed in interactive prompt banner.
436
Georg Brandlfa166682005-12-17 21:45:17 +0000437- Implementation of PEP 341 - Unification of try/except and try/finally.
438 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000439 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000440
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000441- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
442 now encodes backslash correctly.
443
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000444- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
445
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000446- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000447 and long longs.
448
Neal Norwitz67715f02005-11-09 06:59:35 +0000449- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000450 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000451 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000452
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000453- Replaced most Unicode charmap codecs with new ones using the
454 new Unicode translate string feature in the builtin charmap
455 codec; the codecs were created from the mapping tables available
456 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
457 encodings now include a mapping for the Apple logo)
458
Tim Peterse3547fd2005-12-16 23:13:57 +0000459- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000460
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000461- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000462
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000463- A new AST parser implementation was completed. The abstract
464 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000465 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000466
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000467- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000468 The following code now raises a SyntaxError: foo(a = i for i in range(10))
469
Neal Norwitz708e51a2005-10-03 04:48:15 +0000470- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
471
Neal Norwitz11bd1192005-10-03 00:54:56 +0000472- SF Bug #887946: fix segfault when redirecting stdin from a directory.
473 Provide a warning when a directory is passed on the command line.
474
Neal Norwitz40d37812005-10-02 01:48:49 +0000475- Fix segfault with invalid coding.
476
477- SF bug #772896: unknown encoding results in MemoryError.
478
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000479- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000480 supported a __len__() method which evaluated to False when the iterator
481 was empty.
482
Guido van Rossum630db602005-09-20 18:49:54 +0000483- On 64-bit platforms, when __len__() returns a value that cannot be
484 represented as a C int, raise OverflowError.
485
Skip Montanarof8948ca2005-09-19 03:54:46 +0000486- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000487 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000488
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000489- SF bug #893549: parsing keyword arguments was broken with a few format
490 codes.
491
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000492- Changes donated by Elemental Security to make it work on AIX 5.3
493 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
494 bug #105470: test_pwd fails on 64bit system (Opteron).
495
Guido van Rossum539c6622005-09-14 17:49:54 +0000496- Changes donated by Elemental Security to make it work on HP-UX 11 on
497 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
498
Georg Brandl4550b8d2005-08-26 06:43:52 +0000499- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000500 (fixes bug #1119418).
501
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000502- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
503
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000504- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
505 exceptions that cause a function to exit.
506
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000507- The implementation of set() and frozenset() was revised to use its
508 own internal data structure. Memory consumption is reduced by 1/3
509 and there are modest speed-ups as well. The API is unchanged.
510
Tim Petersde7990b2005-07-17 23:45:23 +0000511- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
512
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000513- SF bug #1229429: PyObject_CallMethod failed to decrement some
514 reference counts in some error exit cases.
515
Tim Petersecc6e6a2005-07-10 22:30:55 +0000516- SF bug #1185883: Python's small-object memory allocator took over
517 a block managed by the platform C library whenever a realloc specified
518 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000519 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000520 portable way to copy data from the C-managed block into Python's
521 small-object space without risking a memory fault. Python's small-object
522 realloc now leaves such blocks under the control of the platform C
523 realloc.
524
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000525- SF bug #1232517: An overflow error was not detected properly when
526 attempting to convert a large float to an int in os.utime().
527
Raymond Hettinger3296e692005-06-29 23:29:56 +0000528- SF bug #1224347: hex longs now print with lowercase letters just
529 like their int counterparts.
530
Michael W. Hudson188d4362005-06-20 16:52:57 +0000531- SF bug #1163563: the original fix for bug #1010677 ("thread Module
532 Breaks PyGILState_Ensure()") broke badly in the case of multiple
533 interpreter states; back out that fix and do a better job (see
534 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
535 for a longer write-up of the problem).
536
Michael W. Hudsondf888462005-06-03 14:41:55 +0000537- SF patch #1180995: marshal now uses a binary format by default when
538 serializing floats.
539
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000540- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
541 the routines that promise to produce IEEE 754 binary representations
542 of floats now simply copy bytes around.
543
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000544- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
545 278.
546
Brett Cannonc3647ac2005-04-26 03:45:26 +0000547- patch #1109424: int, long, float, complex, and unicode now check for the
548 proper magic slot for type conversions when subclassed. Previously the
549 magic slot was ignored during conversion. Semantics now match the way
550 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000551 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000552 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000553 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000554
Barry Warsawc8d907c2005-04-19 23:43:40 +0000555- Descriptors defined in C with a PyGetSetDef structure, where the setter is
556 NULL, now raise an AttributeError when attempting to set or delete the
557 attribute. Previously a TypeError was raised, but this was inconsistent
558 with the equivalent pure-Python implementation.
559
Michael W. Hudson774479c2005-04-18 08:46:17 +0000560- It is now safe to call PyGILState_Release() before
561 PyEval_InitThreads() (note that if there is reason to believe there
562 are multiple threads around you still must call PyEval_InitThreads()
563 before using the Python API; this fix is for extension modules that
564 have no way of knowing if Python is multi-threaded yet).
565
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000566- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
567 disabled caused a crash.
568
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000569- Bug #1165306: instancemethod_new allowed the creation of a method
570 with im_class == im_self == NULL, which caused a crash when called.
571
Tim Petersecc6e6a2005-07-10 22:30:55 +0000572- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000573 fixes the crash seen in bug #1165761
574
Raymond Hettinger96229b12005-03-11 06:49:40 +0000575- Added two new builtins, any() and all().
576
Brett Cannon409d8f22005-03-05 06:47:57 +0000577- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000578 (e.g., ``class C(): pass`` is no longer a syntax error).
579 Patch #1176012 added support to the 'parser' module and 'compiler' package
580 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000581
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000582- Patch #1115086: Support PY_LONGLONG in structmember.
583
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000584- Bug #1155938: new style classes did not check that __init__() was
585 returning None.
586
Tim Petersecc6e6a2005-07-10 22:30:55 +0000587- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000588 ('\') with a specific error message.
589
Martin v. Löwisff232d72005-03-03 09:24:38 +0000590- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
591
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000592- Bug #1124295: the __name__ attribute of file objects was
593 inadvertently made inaccessible in restricted mode.
594
Tim Petersecc6e6a2005-07-10 22:30:55 +0000595- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000596 an ferror() call.
597
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000598- min() and max() now support key= arguments with the same meaning as in
599 list.sort().
600
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000601- The peephole optimizer now performs simple constant folding in expressions:
602 (2+3) --> (5).
603
Raymond Hettingera422c342005-01-11 03:03:27 +0000604- set and frozenset objects can now be marshalled. SF #1098985.
605
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000606- Bug #1077106: Poor argument checking could cause memory corruption
607 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000608
Jeremy Hyltonab630502005-02-04 18:44:06 +0000609- The parser did not complain about future statements in illegal
610 positions. It once again reports a syntax error if a future
611 statement occurs after anything other than a doc string.
612
Neil Schemenauercf52c072005-08-12 17:34:58 +0000613- Change the %s format specifier for str objects so that it returns a
614 unicode instance if the argument is not an instance of basestring and
615 calling __str__ on the argument returns a unicode instance.
616
Tim Petersf4e69282006-02-27 17:15:31 +0000617- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
618 current thread state when the auto-GIL-state machinery knows about
619 it (since the thread state is being deleted, continuing to remember it
620 can't help, but can hurt if another thread happens to get created with
621 the same thread id).

752
Michael W. Hudson8137bea2005-07-27 20:24:40 +0000753- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
754 the request code argument, which results in more C-like behaviour
755 for large or negative values.
756
Tim Petersecc6e6a2005-07-10 22:30:55 +0000757- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlaf410b52005-07-08 22:26:13 +0000759
Georg Brandl6b95f1d2005-06-03 19:47:00 +0000760- Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.

Raymond Hettinger4aec61e2005-03-18 21:20:23 +0000771- collections.deque objects now support a remove() method.
772
Raymond Hettinger984f9bb2005-03-09 16:38:48 +0000773- operator.itemgetter() and operator.attrgetter() now support retrieving

799
Raymond Hettingerb2594052004-12-05 09:25:51 +0000800- itertools.islice() now accepts None for the start and step arguments.
801 This allows islice() to work more readily with slices:
802 islice(s.start, s.stop, s.step)
803
Skip Montanaro0af3ade2005-01-13 04:12:31 +0000804- datetime.datetime() now has a strptime class method which can be used to

809
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000810Library
811-------
812
Nick Coghlan43832302006-04-23 17:04:07 +0000813- PEP 338: new module runpy defines a run_module function to support
814 executing modules which provide access to source code or a code object
815 via the PEP 302 import mechanisms.
816
Anthony Baxter93f5b932006-04-03 08:05:07 +0000817- The email module's parsedate_tz function now sets the daylight savings
818 flag to -1 (unknown) since it can't tell from the date whether it should
819 be set.
820
Fred Drakead5177c2006-04-01 22:14:43 +0000821- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
822 now sport attributes that provide access to the parts of the result.
823
Georg Brandl7f6b67c2006-04-01 08:35:18 +0000824- Patch #1462498: sgmllib now handles entity and character references
825 in attribute values.
826
Anthony Baxterc51ee692006-04-01 00:57:31 +0000827- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000828 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000829 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000830 module will not be built.
831
Tim Petersc17976e2006-04-01 00:26:53 +0000832- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
833 aren't officially supported here, and trying to use them will probably
834 raise an exception some day. But dicts have been allowed, and "mostly
835 worked", so support for them won't go away without warning.
836
Georg Brandl338ef7d2006-03-31 18:42:16 +0000837- Bug #1445068: getpass.getpass() can now be given an explicit stream
838 argument to specify where to write the prompt.
839
Georg Brandl22ec80b2006-03-31 18:25:44 +0000840- Patch #1462313, bug #1443328: the pickle modules now can handle classes
841 that have __private names in their __slots__.

846 key to be used for signing the uploaded code.
847
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000848- Queue.Queue objects now support .task_done() and .join() methods
849 to make it easier to monitor when daemon threads have completed

855
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000856- email 4.0 package now integrated. This is largely the same as the email 3.0
857 package that was included in Python 2.3, except that PEP 8 module names are
858 now used (e.g. mail.message instead of email.Message). The MIME classes
859 have been moved to a subpackage (e.g. email.mime.text instead of
860 email.MIMEText). The old names are still supported for now. Several
861 deprecated Message methods have been removed and lots of bugs have been
862 fixed. More details can be found in the email package documentation.
863
Walter Dörwald40108c92006-03-27 08:15:44 +0000864- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
865 (a subclass of tuple) that provides incremental decoders and encoders
866 (a way to use stateful codecs without the stream API). Python functions
867 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
868 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
869 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000870
Walter Dörwald067db482006-03-15 22:17:27 +0000871- Patch #1359365: Calling next() on a closed StringIO.String object raises
872 a ValueError instead of a StopIteration now (like file and cString.String do).
873 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
874 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000875
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000876- A regrtest option -w was added to re-run failed tests in verbose mode.
877

879 interpreter to exit.
880
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000881- The function get_count() has been added to the gc module, and gc.collect()
882 grew an optional 'generation' argument.

954 expressed at the NIST Hash Function Workshop 10/31/05),
955 is that SHA-256 is a good choice for the time being, but
956 that research should continue, and other alternatives may
957 arise from this research. The larger SHA's also seem OK."

1145 dictates.
1146 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001147 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001148 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001149 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1150 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001151 + reader now allows \r characters to be quoted (previously it only allowed
1152 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001153 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001154 + Dialect classes passed to the module are no longer instantiated by
1155 the module before being parsed (the former validation scheme required
1156 this, but the mechanism was unreliable).
1157 + The dialect registry now contains instances of the internal
1158 C-coded dialect type, rather than references to python objects.
1159 + the internal c-coded dialect type is now immutable.
1160 + register_dialect now accepts the same keyword dialect specifications
1161 as the reader and writer, allowing the user to register dialects
1162 without first creating a dialect class.
1163 + a configurable limit to the size of parsed fields has been added -
1164 previously, an unmatched quote character could result in the entire
1165 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001166 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001167 the parser field size limit (returning the former limit). The initial
1168 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001169 + A line_num attribute has been added to the reader object, which tracks
1170 the number of lines read from the source iterator. This is not
1171 the same as the number of records returned, as records can span
1172 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001173 + reader and writer objects were not being registered with the cyclic-GC.
1174 This has been fixed.
1175
Brett Cannone6539c42005-01-08 02:43:53 +00001176- _DummyThread objects in the threading module now delete self.__block that is
1177 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1178 lock primitives tend to be limited in number and thus should not be wasted on
1179 a _DummyThread object. Fixes bug #1089632.
1180
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001181- The imghdr module now detects Exif files.
1182
Raymond Hettinger6065d322004-12-20 23:51:53 +00001183- StringIO.truncate() now correctly adjusts the size attribute.
1184 (Bug #951915).
1185
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001186- locale.py now uses an updated locale alias table (built using
1187 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1188 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001189 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001190
Raymond Hettinger3557f422004-12-07 12:02:02 +00001191- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1192
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001193- the pickle module no longer accepts the deprecated None option in the
1194 args tuple returned by __reduce__().
1195
Brett Cannon84667c02004-12-07 03:25:18 +00001196- optparse now optionally imports gettext. This allows its use in setup.py.
1197
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001198- the pickle module no longer uses the deprecated bin parameter.
1199
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001200- the shelve module no longer uses the deprecated binary parameter.
1201
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001202- the pstats module no longer uses the deprecated ignore() method.
1203
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001204- the filecmp module no longer uses the deprecated use_statcache argument.
1205
Raymond Hettinger664347b2004-12-04 21:21:53 +00001206- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1207 extended or overridden by subclasses. Formerly, the subclassed method would
1208 be ignored by the rest of the module. (Bug #1078905).
1209
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001210- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001211 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001212
Walter Dörwald36733692004-12-22 12:50:50 +00001213- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1214 once when a size argument is given. This prevents a buffer overflow in the
1215 tokenizer with very long source lines.
1216
Barry Warsaw538561e2006-01-01 21:48:54 +00001217- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1218 immediately after creating the object, without any intervening
1219 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001220
Skip Montanaro05885812005-01-16 20:48:27 +00001221- The reconvert.quote function can now emit triple-quoted strings. The
1222 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001223
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001224- ``UserString.MutableString`` now supports negative indices in
1225 ``__setitem__`` and ``__delitem__``
1226
Greg Ward40407942005-03-05 02:53:17 +00001227- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1228 correctly.
1229
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001230- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1231 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1232 character even if the user has passed a size parameter to get a proper
1233 line ending. Remove the special handling of a "\r\n" that has been split
1234 between two lines.
1235
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001236- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1237 about illegal code points. The codec now supports PEP 293 style error
1238 handlers.
1239
Walter Dörwald78a78b02005-09-01 12:04:29 +00001240- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001241 from the input stream, so that the output is a byte string in the correct
1242 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001243
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001244- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1245 considering it exactly like a '*'.
1246
Walter Dörwald007f8df2005-10-09 19:42:27 +00001247- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1248 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001249
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001250- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1251
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001252- Patch #1413711: Certain patterns of differences were making difflib
1253 touch the recursion limit.
1254
Walter Dörwald58917a62006-03-31 15:26:22 +00001255- Bug #947906: An object oriented interface has been added to the calendar
1256 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001257 called as a script (e.g. via ``python -mcalendar``). Localized month and
1258 weekday names can be ouput (even if an exotic encoding is used) using
1259 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001260
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001261Build
1262-----
1263
Neal Norwitz602d3392006-03-31 08:21:40 +00001264- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1265 by using -mieee gcc option.
1266
Martin v. Löwis86d66262006-02-17 08:40:11 +00001267- Patch #1432345: Make python compile on DragonFly.
1268
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001269- Build support for Win64-AMD64 was added.
1270
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001271- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1272
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001273- Patch #881820: look for openpty and forkpty also in libbsd.
1274
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001275- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1276 The zlib module is now builtin on Windows.
1277
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001278- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1279
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001280- Bug #1189330: configure did not correctly determine the necessary
1281 value of LINKCC if python was built with GCC 4.0.
1282
Trent Mick8321b422005-07-26 02:29:21 +00001283- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1284 vulnerability in zlib 1.2.1 and 1.2.2.
1285
Brett Cannon08cd5982005-04-24 22:26:38 +00001286- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1287 flags that change binary compatibility. Changes were also made to
1288 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001289 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001290
Bob Ippolitoed233462005-03-29 13:47:59 +00001291- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1292 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1293 no longer exists). This configure patch makes things right.
1294
Martin v. Löwise2713be2005-03-08 15:03:08 +00001295- Bug #1158607: Build with --disable-unicode again.
1296
Brett Cannon46d96232005-02-16 00:07:19 +00001297- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1298 defined. Discovered as a result of not being able to build on OS X.
1299
Brett Cannon516592f2004-12-07 00:42:59 +00001300- setup.py now uses the directories specified in LDFLAGS using the -L option
1301 and in CPPFLAGS using the -I option for adding library and include
1302 directories, respectively, for compiling extension modules against. This has
1303 led to the core being compiled using the values in CPPFLAGS. It also removes
1304 the need for the special-casing of both DarwinPorts and Fink for darwin since
1305 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1306 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1307 Fink, ``-I/opt/local/include`` for DarwinPorts).
1308
Brett Cannon43802422005-02-10 20:48:03 +00001309- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1310 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1311 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1312 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001314C API
1315-----
1316
Tim Petersc9d78aa2006-03-26 23:27:58 +00001317- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1318 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1319 is obtained via the ``PyObject_`` family, it must be released via the
1320 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1321 always been officially true, but when Python's small-object allocator was
1322 introduced, an attempt was made to cater to a few extension modules
1323 discovered at the time that obtained memory via ``PyObject_New`` but
1324 released it via ``PyMem_DEL``. It's years later, and if such code still
1325 exists it will fail now (probably with segfaults, but calling wrong
1326 low-level memory management functions can yield many symptoms).
1327
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001328- Added a C API for set and frozenset objects.
1329
Raymond Hettinger66517482004-12-03 11:45:13 +00001330- Removed PyRange_New().
1331
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001332- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1333 mapping argument now. This string is used as a mapping table. Byte values
1334 greater than the length of the string and 0xFFFE are treated as undefined
1335 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001342
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001343- Patch #1276356: New resource "urlfetch" is implemented. This enables
