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 Peters696cf432006-05-24 21:10:40 +000015- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
16 of-2 bases. The largest speedup is for inputs with about 1000 decimal
17 digits. Conversion from non-power-of-2 bases remains quadratic-time in
18 the number of input digits (it was and remains linear-time for bases
19 2, 4, 8, 16 and 32).
20
Tim Petersb713ec22006-05-23 18:45:30 +000021- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
22 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
23 an integer close to ``sys.maxint``. This was repaired by patch
24 #1335972, which also gives a nice speedup.
25
Richard Jonescebbefc2006-05-23 18:28:17 +000026- Patch #1337051: reduced size of frame objects.
27
28- PyErr_NewException now accepts a tuple of base classes as its
29 "base" parameter.
30
Richard Jones7c88dcc2006-05-23 10:37:38 +000031- Patch #876206: function call speedup by retaining allocated frame
32 objects.
33
Georg Brandl7b90e162006-05-18 07:01:27 +000034- Bug #1462152: file() now checks more thoroughly for invalid mode
35 strings and removes a possible "U" before passing the mode to the
36 C library function.
37
Neal Norwitz1004a532006-05-15 07:17:23 +000038- Patch #1488312, Fix memory alignment problem on SPARC in unicode
39
Neal Norwitz373f0a72006-05-15 07:04:36 +000040- Bug #1487966: Fix SystemError with conditional expression in assignment
41
Martin v. Löwis879768d2006-05-11 13:28:43 +000042- WindowsError now has two error code attributes: errno, which carries
43 the error values from errno.h, and winerror, which carries the error
44 values from winerror.h. Previous versions put the winerror.h values
45 (from GetLastError()) into the errno attribute.
46
Martin v. Löwis77736712006-05-04 05:51:03 +000047- Patch #1475845: Raise IndentationError for unexpected indent.
48
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000049- Patch #1479181: split open() and file() from being aliases for each other.
50
Neal Norwitz7a5fc282006-05-15 06:48:14 +000051Extension Modules
52-----------------
53
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000054- Patch #1493701: performance enhancements for struct module.
55
Georg Brandl378d5922006-05-17 14:26:50 +000056- Patch #1490224: time.altzone is now set correctly on Cygwin.
57
Georg Brandl8d3342b2006-05-16 07:38:27 +000058- Patch #1435422: zlib's compress and decompress objects now have a
59 copy() method.
60
Neal Norwitz7a5fc282006-05-15 06:48:14 +000061- On Win32, os.listdir now supports arbitrarily-long Unicode path names
62 (up to the system limit of 32K characters).
63
64- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
65 As a result, these functions now raise WindowsError instead of OSError.
66
Tim Peters7a822da2006-05-25 21:50:17 +000067- ``time.clock()`` on Win64 should use the high-performance Windows
68 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
69 Windows platforms).
70
Neal Norwitz7a5fc282006-05-15 06:48:14 +000071- Calling Tk_Init twice is refused if the first call failed as that
72 may deadlock.
73
74Library
75-------
76
Bob Ippolito7298f272006-05-23 18:43:47 +000077- Patch #1281707: speed up gzip.readline.
78
Georg Brandlb89316f2006-05-17 15:51:16 +000079- Patch #1180296: Two new functions were added to the locale module:
80 format_string() to get the effect of "format % items" but locale-aware,
81 and currency() to format a monetary number with currency sign.
82
Georg Brandle3a25832006-05-17 14:56:04 +000083- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
84 and several features added, such as speed and geometry control.
85
Georg Brandl49c8f4c2006-05-15 19:30:35 +000086- Patch #1488881: add support for external file objects in bz2 compressed
87 tarfiles.
88
Neal Norwitz7a5fc282006-05-15 06:48:14 +000089- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
90 stdout arguments, making it possible to redirect input and output
91 for remote debugging.
92
93- Patch #1484695: Update the tarfile module to version 0.8. This fixes
94 a couple of issues, notably handling of long file names using the
95 GNU LONGNAME extension.
96
97- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
98 new flag when ``name`` is already the name of an option flag.
99
100- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
101 package.
102
103- Patch #1472854: make the rlcompleter.Completer class usable on non-
104 UNIX platforms.
105
106- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Martin v. Löwisa43190b2006-05-22 09:15:18 +0000111- Patch #1492356: Port to Windows CE.
112
Neal Norwitz58e28882006-05-19 07:00:58 +0000113- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

129What's New in Python 2.5 alpha 2?
130=================================
131
132*Release date: 27-APR-2006*
133
134Core and builtins
135-----------------
136
Thomas Heller1b046642006-04-18 18:51:06 +0000137- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
138 by converting these apis from macros into exported functions again:
139
140 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
141 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
142 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
143 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
144 PyRun_String Py_CompileString
145
Martin v. Löwis45294a92006-04-18 06:24:08 +0000146- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
147
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000148- All uses of PyStructSequence_InitType have been changed to initialize
149 the type objects only once, even if the interpreter is initialized
150 multiple times.
151
Neal Norwitz61546162006-04-14 05:20:28 +0000152- Bug #1454485, array.array('u') could crash the interpreter. This was
153 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
154 to unicode when it didn't make sense. 'u#' now requires a unicode string.
155
156- Py_UNICODE is unsigned. It was always documented as unsigned, but
157 due to a bug had a signed value in previous versions.
158
Tim Peters3a5e8b12006-04-11 01:44:07 +0000159- Patch #837242: ``id()`` of any Python object always gives a positive
160 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
161 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000162 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000163 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000164
Tim Peters3a5e8b12006-04-11 01:44:07 +0000165 def __hash__(self):
166 return id(self) # WRONG
167
168 because a hash result must be a (short) Python int but it was always
169 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000170 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000171 was always usable as a hash value before this patch. That's no longer
172 necessarily so.
173
174- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000175 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000176 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000177 #1454844)
178
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000179- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
180 involving generators that have paused outside of any ``try`` or ``with``
181 blocks. (In 2.5a1, a paused generator that was part of a reference
182 cycle could not be garbage collected, regardless of whether it was
183 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000185Extension Modules

187
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000188- Patch #1191065: Fix preprocessor problems on systems where recvfrom
189 is a macro.
190
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000191- Bug #1467952: os.listdir() now correctly raises an error if readdir()
192 fails with an error condition.
193
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000194- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
195
196- Bug #1117761: bsddb.*open() no longer raises an exception when using
197 the cachesize parameter.
198
199- Bug #1149413: bsddb.*open() no longer raises an exception when using
200 a temporary db (file=None) with the 'n' flag to truncate on open.
201
202- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
203 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000204
Armin Rigoa9017c32006-04-19 11:50:27 +0000205- Patch #1062014: AF_UNIX sockets under Linux have a special
206 abstract namespace that is now fully supported.
207
Anthony Baxter51bcb682006-04-05 14:51:42 +0000208Library
209-------
210
Tim Peters711bf302006-04-25 03:31:36 +0000211- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
212 a doctest to be skipped (the code is not run, and the expected output
213 or exception is ignored).
214
Nick Coghlanda2268f2006-04-24 04:37:15 +0000215- Fixed contextlib.nested to cope with exceptions being raised and
216 caught inside exit handlers.
217
Greg Wardab05edc2006-04-23 03:47:58 +0000218- Updated optparse module to Optik 1.5.1 (allow numeric constants in
219 hex, octal, or binary; add ``append_const`` action; keep going if
220 gettext cannot be imported; added ``OptionParser.destroy()`` method;
221 added ``epilog`` for better help generation).
222
Tim Peters21fbd572006-04-21 21:18:10 +0000223- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
224 called from a thread spawned as a side effect of importing a module.
225
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000226- The pydoc module now supports documenting packages contained in
227 .zip or .egg files.
228
229- The pkgutil module now has several new utility functions, such
230 as ``walk_packages()`` to support working with packages that are either
231 in the filesystem or zip files.
232
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000233- The mailbox module can now modify and delete messages from
234 mailboxes, in addition to simply reading them. Thanks to Gregory
235 K. Johnson for writing the code, and to the 2005 Google Summer of
236 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000237
Tim Petersc7605f22006-04-17 21:12:33 +0000238- The ``__del__`` method of class ``local`` in module ``_threading_local``
239 returned before accomplishing any of its intended cleanup.

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000245- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
246
Anthony Baxtere29002c2006-04-12 12:07:31 +0000247- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
248 Windows. Bug #1469163.
249
Phillip J. Eby47032112006-04-11 01:07:43 +0000250- The warnings, linecache, inspect, traceback, site, and doctest modules
251 were updated to work correctly with modules imported from zipfiles or
252 via other PEP 302 __loader__ objects.
253
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000254- Patch #1467770: Reduce usage of subprocess._active to processes which
255 the application hasn't waited on.
256

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000274- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
275 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000276 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000277 CXX from --with-cxx-main, see description in README.
278

Nick Coghlanda2268f2006-04-24 04:37:15 +0000290- test_contextlib now checks contextlib.nested can cope with exceptions
291 being raised and caught inside exit handlers.

294
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000295- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
296 it separately and by hand. It also wasn't cleaning up its changes to
297 the current Decimal context.
298
Thomas Woutersabd08882006-04-26 15:53:30 +0000299- regrtest.py now has a -M option to run tests that test the new limits of
300 containers, on 64-bit architectures. Running these tests is only sensible
301 on 64-bit machines with more than two gigabytes of memory. The argument
302 passed is the maximum amount of memory for the tests to use.

Nick Coghlan43832302006-04-23 17:04:07 +0000331- PEP 338: -m command line switch now delegates to runpy.run_module
332 allowing it to support modules in packages and zipfiles
333
Martin v. Löwisc661b882006-04-20 04:54:23 +0000334- On Windows, .DLL is not an accepted file name extension for
335 extension modules anymore; extensions are only found if they
336 end in .PYD.
337
Martin v. Löwisea62d252006-04-03 10:56:49 +0000338- Bug #1421664: sys.stderr.encoding is now set to the same value as
339 sys.stdout.encoding.
340
Neal Norwitz92e212f2006-04-03 04:48:37 +0000341- __import__ accepts keyword arguments.
342
Georg Brandlccadf842006-03-31 18:54:53 +0000343- Patch #1460496: round() now accepts keyword arguments.
344
Anthony Baxter262c00a2006-03-30 10:53:17 +0000345- Fixed bug #1459029 - unicode reprs were double-escaped.
346
Hye-Shik Changd478f342006-03-23 12:32:36 +0000347- Patch #1396919: The system scope threads are reenabled on FreeBSD
348 5.4 and later versions.
349
Neal Norwitze98ccf62006-03-23 05:39:47 +0000350- Bug #1115379: Compiling a Unicode string with an encoding declaration
351 now gives a SyntaxError.
352
Georg Brandlabd1ff82006-03-18 07:59:59 +0000353- Previously, Python code had no easy way to access the contents of a
354 cell object. Now, a ``cell_contents`` attribute has been added
355 (closes patch #1170323).
356
Tim Peterscf79aac2006-03-16 01:14:46 +0000357- Patch #1123430: Python's small-object allocator now returns an arena to
358 the system ``free()`` when all memory within an arena becomes unused
359 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
360 freed. Some applications will see a drop in virtual memory size now,
361 especially long-running applications that, from time to time, temporarily
362 use a large number of small objects. Note that when Python returns an
363 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000364 platform C library will in turn return that memory to the operating system.
365 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000366 appears to be effective at least on Microsoft C and gcc-based systems.
367 Thanks to Evan Jones for hard work and patience.
368
Georg Brandl533ff6f2006-03-08 18:09:27 +0000369- Patch #1434038: property() now uses the getter's docstring if there is
370 no "doc" argument given. This makes it possible to legitimately use
371 property() as a decorator to produce a read-only property.
372
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000373- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
374 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
375 of requiring an int or long in slicing and a few other contexts, enabling
376 other objects (e.g. Numeric Python's integers) to be used as slice indices.
377
Neal Norwitz995acdf2006-03-07 05:01:00 +0000378- Fixed various bugs reported by Coverity's Prevent tool.
379
Brett Cannonbf364092006-03-01 04:25:17 +0000380- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
381 new exception base class, BaseException, which has a new message attribute.
382 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
383 Raising a string exception now raises a DeprecationWarning.
384
Thomas Woutersfb609f42006-02-28 16:37:25 +0000385- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
386 explicitly relative, using 'from .module import name' to mean 'from the same
387 package as this module is in. Imports without dots still default to the
388 old relative-then-absolute, unless 'from __future__ import
389 absolute_import' is used.
390
Brett Cannona7446e32006-02-27 23:39:10 +0000391- Properly check if 'warnings' raises an exception (usually when a filter set
392 to "error" is triggered) when raising a warning for raising string
393 exceptions.
394
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000395- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000396 The name was removed from Include/code.h.
397
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000398- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000399
Guido van Rossum1968ad32006-02-25 22:38:04 +0000400- Patch 1433928:
401 - The copy module now "copies" function objects (as atomic objects).
402 - dict.__getitem__ now looks for a __missing__ hook before raising
403 KeyError.
404
Tim Peters84ef21c2006-02-28 20:39:06 +0000405- PEP 343: with statement implemented. Needs ``from __future__ import
406 with_statement``. Use of 'with' as a variable will generate a warning.
407 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000408 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000409 The following objects have __context__ methods:
410 - The built-in file type.
411 - The thread.LockType type.
412 - The following types defined by the threading module:
413 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
414 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000415
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000416- Fix the encodings package codec search function to only search
417 inside its own package. Fixes problem reported in patch #1433198.
418
419 Note: Codec packages should implement and register their own
420 codec search function. PEP 100 has the details.
421
Martin v. Löwis18e16552006-02-15 17:27:45 +0000422- PEP 353: Using ssize_t as the index type.
423
Neal Norwitzfc76d632006-01-10 06:03:13 +0000424- Patch #1400181, fix unicode string formatting to not use the locale.
425 This is how string objects work. u'%f' could use , instead of .
426 for the decimal point. Now both strings and unicode always use periods.
427
Neal Norwitz671b9e32006-01-09 07:07:12 +0000428- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
429 configure would break checking curses.h.
430
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000431- Bug #959576: The pwd module is now builtin. This allows Python to be
432 built on UNIX platforms without $HOME set.
433
Neal Norwitzc10978f2005-12-19 06:07:16 +0000434- Bug #1072182, fix some potential problems if characters are signed.
435
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000436- Bug #889500, fix line number on SyntaxWarning for global declarations.
437
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000438- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
439
Neal Norwitze7214a12005-12-18 05:03:17 +0000440- Support for converting hex strings to floats no longer works.
441 This was not portable. float('0x3') now raises a ValueError.
442
Barry Warsaw2a38a862005-12-18 01:27:35 +0000443- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000444 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000445 is now displayed in interactive prompt banner.
446
Georg Brandlfa166682005-12-17 21:45:17 +0000447- Implementation of PEP 341 - Unification of try/except and try/finally.
448 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000449 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000450
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000451- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
452 now encodes backslash correctly.
453
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000454- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
455
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000456- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000457 and long longs.
458
Neal Norwitz67715f02005-11-09 06:59:35 +0000459- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000460 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000461 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000462
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000463- Replaced most Unicode charmap codecs with new ones using the
464 new Unicode translate string feature in the builtin charmap
465 codec; the codecs were created from the mapping tables available
466 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
467 encodings now include a mapping for the Apple logo)
468
Tim Peterse3547fd2005-12-16 23:13:57 +0000469- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000470
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000471- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000472
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000473- A new AST parser implementation was completed. The abstract
474 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000475 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000477- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000478 The following code now raises a SyntaxError: foo(a = i for i in range(10))
479
Neal Norwitz708e51a2005-10-03 04:48:15 +0000480- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
481
Neal Norwitz11bd1192005-10-03 00:54:56 +0000482- SF Bug #887946: fix segfault when redirecting stdin from a directory.
483 Provide a warning when a directory is passed on the command line.
484
Neal Norwitz40d37812005-10-02 01:48:49 +0000485- Fix segfault with invalid coding.
486
487- SF bug #772896: unknown encoding results in MemoryError.
488
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000489- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000490 supported a __len__() method which evaluated to False when the iterator
491 was empty.
492
Guido van Rossum630db602005-09-20 18:49:54 +0000493- On 64-bit platforms, when __len__() returns a value that cannot be
494 represented as a C int, raise OverflowError.
495
Skip Montanarof8948ca2005-09-19 03:54:46 +0000496- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000497 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000498
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000499- SF bug #893549: parsing keyword arguments was broken with a few format
500 codes.
501
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000502- Changes donated by Elemental Security to make it work on AIX 5.3
503 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
504 bug #105470: test_pwd fails on 64bit system (Opteron).
505
Guido van Rossum539c6622005-09-14 17:49:54 +0000506- Changes donated by Elemental Security to make it work on HP-UX 11 on
507 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
508
Georg Brandl4550b8d2005-08-26 06:43:52 +0000509- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000510 (fixes bug #1119418).
511
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000512- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
513
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000514- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
515 exceptions that cause a function to exit.
516
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000517- The implementation of set() and frozenset() was revised to use its
518 own internal data structure. Memory consumption is reduced by 1/3
519 and there are modest speed-ups as well. The API is unchanged.
520
Tim Petersde7990b2005-07-17 23:45:23 +0000521- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
522
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000523- SF bug #1229429: PyObject_CallMethod failed to decrement some
524 reference counts in some error exit cases.
525
Tim Petersecc6e6a2005-07-10 22:30:55 +0000526- SF bug #1185883: Python's small-object memory allocator took over
527 a block managed by the platform C library whenever a realloc specified
528 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000529 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000530 portable way to copy data from the C-managed block into Python's
531 small-object space without risking a memory fault. Python's small-object
532 realloc now leaves such blocks under the control of the platform C
533 realloc.
534
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000535- SF bug #1232517: An overflow error was not detected properly when
536 attempting to convert a large float to an int in os.utime().
537
Raymond Hettinger3296e692005-06-29 23:29:56 +0000538- SF bug #1224347: hex longs now print with lowercase letters just
539 like their int counterparts.
540
Michael W. Hudson188d4362005-06-20 16:52:57 +0000541- SF bug #1163563: the original fix for bug #1010677 ("thread Module
542 Breaks PyGILState_Ensure()") broke badly in the case of multiple
543 interpreter states; back out that fix and do a better job (see
544 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
545 for a longer write-up of the problem).
546
Michael W. Hudsondf888462005-06-03 14:41:55 +0000547- SF patch #1180995: marshal now uses a binary format by default when
548 serializing floats.
549
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000550- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
551 the routines that promise to produce IEEE 754 binary representations
552 of floats now simply copy bytes around.
553
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000554- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
555 278.
556
Brett Cannonc3647ac2005-04-26 03:45:26 +0000557- patch #1109424: int, long, float, complex, and unicode now check for the
558 proper magic slot for type conversions when subclassed. Previously the
559 magic slot was ignored during conversion. Semantics now match the way
560 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000561 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000562 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000563 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000564
Barry Warsawc8d907c2005-04-19 23:43:40 +0000565- Descriptors defined in C with a PyGetSetDef structure, where the setter is
566 NULL, now raise an AttributeError when attempting to set or delete the
567 attribute. Previously a TypeError was raised, but this was inconsistent
568 with the equivalent pure-Python implementation.
569
Michael W. Hudson774479c2005-04-18 08:46:17 +0000570- It is now safe to call PyGILState_Release() before
571 PyEval_InitThreads() (note that if there is reason to believe there
572 are multiple threads around you still must call PyEval_InitThreads()
573 before using the Python API; this fix is for extension modules that
574 have no way of knowing if Python is multi-threaded yet).
575
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000576- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
577 disabled caused a crash.
578
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000579- Bug #1165306: instancemethod_new allowed the creation of a method
580 with im_class == im_self == NULL, which caused a crash when called.
581
Tim Petersecc6e6a2005-07-10 22:30:55 +0000582- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000583 fixes the crash seen in bug #1165761
584
Raymond Hettinger96229b12005-03-11 06:49:40 +0000585- Added two new builtins, any() and all().
586
Brett Cannon409d8f22005-03-05 06:47:57 +0000587- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000588 (e.g., ``class C(): pass`` is no longer a syntax error).
589 Patch #1176012 added support to the 'parser' module and 'compiler' package
590 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000591
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000592- Patch #1115086: Support PY_LONGLONG in structmember.
593
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000594- Bug #1155938: new style classes did not check that __init__() was
595 returning None.
596
Tim Petersecc6e6a2005-07-10 22:30:55 +0000597- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000598 ('\') with a specific error message.
599
Martin v. Löwisff232d72005-03-03 09:24:38 +0000600- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
601
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000602- Bug #1124295: the __name__ attribute of file objects was
603 inadvertently made inaccessible in restricted mode.

Tim Petersecc6e6a2005-07-10 22:30:55 +0000605- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000606 an ferror() call.
607
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000608- min() and max() now support key= arguments with the same meaning as in
609 list.sort().

612 (2+3) --> (5).
613
Raymond Hettingera422c342005-01-11 03:03:27 +0000614- set and frozenset objects can now be marshalled. SF #1098985.

Jeremy Hyltonab630502005-02-04 18:44:06 +0000619- The parser did not complain about future statements in illegal
620 positions. It once again reports a syntax error if a future
621 statement occurs after anything other than a doc string.
622
Neil Schemenauercf52c072005-08-12 17:34:58 +0000623- Change the %s format specifier for str objects so that it returns a
624 unicode instance if the argument is not an instance of basestring and
625 calling __str__ on the argument returns a unicode instance.
626
Tim Petersf4e69282006-02-27 17:15:31 +0000627- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
628 current thread state when the auto-GIL-state machinery knows about
629 it (since the thread state is being deleted, continuing to remember it
630 can't help, but can hurt if another thread happens to get created with
631 the same thread id).

Raymond Hettingerb2594052004-12-05 09:25:51 +0000810- itertools.islice() now accepts None for the start and step arguments.
811 This allows islice() to work more readily with slices:

819
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000820Library
821-------
822
Nick Coghlan43832302006-04-23 17:04:07 +0000823- PEP 338: new module runpy defines a run_module function to support
824 executing modules which provide access to source code or a code object
825 via the PEP 302 import mechanisms.
826
Anthony Baxter93f5b932006-04-03 08:05:07 +0000827- The email module's parsedate_tz function now sets the daylight savings
828 flag to -1 (unknown) since it can't tell from the date whether it should
829 be set.
830
Fred Drakead5177c2006-04-01 22:14:43 +0000831- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results

835 in attribute values.
836
Anthony Baxterc51ee692006-04-01 00:57:31 +0000837- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000838 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000839 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000840 module will not be built.
841
Tim Petersc17976e2006-04-01 00:26:53 +0000842- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
843 aren't officially supported here, and trying to use them will probably
844 raise an exception some day. But dicts have been allowed, and "mostly
845 worked", so support for them won't go away without warning.
846
Georg Brandl338ef7d2006-03-31 18:42:16 +0000847- Bug #1445068: getpass.getpass() can now be given an explicit stream
848 argument to specify where to write the prompt.
849
Georg Brandl22ec80b2006-03-31 18:25:44 +0000850- Patch #1462313, bug #1443328: the pickle modules now can handle classes

865
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000866- email 4.0 package now integrated. This is largely the same as the email 3.0
867 package that was included in Python 2.3, except that PEP 8 module names are
868 now used (e.g. mail.message instead of email.Message). The MIME classes
869 have been moved to a subpackage (e.g. email.mime.text instead of
870 email.MIMEText). The old names are still supported for now. Several
871 deprecated Message methods have been removed and lots of bugs have been
872 fixed. More details can be found in the email package documentation.
873
Walter Dörwald40108c92006-03-27 08:15:44 +0000874- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
875 (a subclass of tuple) that provides incremental decoders and encoders
876 (a way to use stateful codecs without the stream API). Python functions
877 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
878 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
879 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000880
Walter Dörwald067db482006-03-15 22:17:27 +0000881- Patch #1359365: Calling next() on a closed StringIO.String object raises

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

Martin v. Löwis22b457e2005-01-16 08:40:58 +00001145- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1146
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001147- Enhancements to the csv module:
1148
1149 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001150 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001151 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001152 + Dialect parameter parsing has been re-implemented to improve error
1153 reporting.
1154 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1155 dictates.
1156 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001157 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001158 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001159 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1160 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001161 + reader now allows \r characters to be quoted (previously it only allowed
1162 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001163 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001164 + Dialect classes passed to the module are no longer instantiated by
1165 the module before being parsed (the former validation scheme required
1166 this, but the mechanism was unreliable).
1167 + The dialect registry now contains instances of the internal
1168 C-coded dialect type, rather than references to python objects.
1169 + the internal c-coded dialect type is now immutable.
1170 + register_dialect now accepts the same keyword dialect specifications
1171 as the reader and writer, allowing the user to register dialects
1172 without first creating a dialect class.
1173 + a configurable limit to the size of parsed fields has been added -
1174 previously, an unmatched quote character could result in the entire
1175 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001176 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001177 the parser field size limit (returning the former limit). The initial
1178 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001179 + A line_num attribute has been added to the reader object, which tracks
1180 the number of lines read from the source iterator. This is not
1181 the same as the number of records returned, as records can span
1182 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001183 + reader and writer objects were not being registered with the cyclic-GC.
1184 This has been fixed.
1185
Brett Cannone6539c42005-01-08 02:43:53 +00001186- _DummyThread objects in the threading module now delete self.__block that is
1187 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1188 lock primitives tend to be limited in number and thus should not be wasted on
1189 a _DummyThread object. Fixes bug #1089632.
1190
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001191- The imghdr module now detects Exif files.
1192
Raymond Hettinger6065d322004-12-20 23:51:53 +00001193- StringIO.truncate() now correctly adjusts the size attribute.
1194 (Bug #951915).
1195
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001196- locale.py now uses an updated locale alias table (built using
1197 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1198 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001199 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001200
Raymond Hettinger3557f422004-12-07 12:02:02 +00001201- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1202
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001203- the pickle module no longer accepts the deprecated None option in the
1204 args tuple returned by __reduce__().
1205
Brett Cannon84667c02004-12-07 03:25:18 +00001206- optparse now optionally imports gettext. This allows its use in setup.py.
1207
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001208- the pickle module no longer uses the deprecated bin parameter.
1209
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001210- the shelve module no longer uses the deprecated binary parameter.
1211
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001212- the pstats module no longer uses the deprecated ignore() method.
1213
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001214- the filecmp module no longer uses the deprecated use_statcache argument.
1215
Raymond Hettinger664347b2004-12-04 21:21:53 +00001216- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1217 extended or overridden by subclasses. Formerly, the subclassed method would
1218 be ignored by the rest of the module. (Bug #1078905).
1219
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001220- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001221 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001222
Walter Dörwald36733692004-12-22 12:50:50 +00001223- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1224 once when a size argument is given. This prevents a buffer overflow in the
1225 tokenizer with very long source lines.
1226
Barry Warsaw538561e2006-01-01 21:48:54 +00001227- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1228 immediately after creating the object, without any intervening
1229 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001230
Skip Montanaro05885812005-01-16 20:48:27 +00001231- The reconvert.quote function can now emit triple-quoted strings. The
1232 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001233
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001234- ``UserString.MutableString`` now supports negative indices in
1235 ``__setitem__`` and ``__delitem__``
1236
Greg Ward40407942005-03-05 02:53:17 +00001237- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1238 correctly.
1239
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001240- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1241 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1242 character even if the user has passed a size parameter to get a proper
1243 line ending. Remove the special handling of a "\r\n" that has been split
1244 between two lines.
1245
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001246- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1247 about illegal code points. The codec now supports PEP 293 style error
1248 handlers.
1249
Walter Dörwald78a78b02005-09-01 12:04:29 +00001250- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001251 from the input stream, so that the output is a byte string in the correct
1252 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001253
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001254- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1255 considering it exactly like a '*'.
1256
Walter Dörwald007f8df2005-10-09 19:42:27 +00001257- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1258 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001259
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001260- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1261
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001262- Patch #1413711: Certain patterns of differences were making difflib
1263 touch the recursion limit.
1264
Walter Dörwald58917a62006-03-31 15:26:22 +00001265- Bug #947906: An object oriented interface has been added to the calendar
1266 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001267 called as a script (e.g. via ``python -mcalendar``). Localized month and
1268 weekday names can be ouput (even if an exotic encoding is used) using
1269 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001270
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001271Build
1272-----
1273
Neal Norwitz602d3392006-03-31 08:21:40 +00001274- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1275 by using -mieee gcc option.
1276
Martin v. Löwis86d66262006-02-17 08:40:11 +00001277- Patch #1432345: Make python compile on DragonFly.
1278
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001279- Build support for Win64-AMD64 was added.
1280
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001281- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1282
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001283- Patch #881820: look for openpty and forkpty also in libbsd.
1284
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001285- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1286 The zlib module is now builtin on Windows.
1287
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001288- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1289
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001290- Bug #1189330: configure did not correctly determine the necessary
1291 value of LINKCC if python was built with GCC 4.0.
1292
Trent Mick8321b422005-07-26 02:29:21 +00001293- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1294 vulnerability in zlib 1.2.1 and 1.2.2.
1295
Brett Cannon08cd5982005-04-24 22:26:38 +00001296- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1297 flags that change binary compatibility. Changes were also made to
1298 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001299 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001300
Bob Ippolitoed233462005-03-29 13:47:59 +00001301- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1302 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1303 no longer exists). This configure patch makes things right.
1304
Martin v. Löwise2713be2005-03-08 15:03:08 +00001305- Bug #1158607: Build with --disable-unicode again.
1306
Brett Cannon46d96232005-02-16 00:07:19 +00001307- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1308 defined. Discovered as a result of not being able to build on OS X.
1309
Brett Cannon516592f2004-12-07 00:42:59 +00001310- setup.py now uses the directories specified in LDFLAGS using the -L option
1311 and in CPPFLAGS using the -I option for adding library and include
1312 directories, respectively, for compiling extension modules against. This has
1313 led to the core being compiled using the values in CPPFLAGS. It also removes
1314 the need for the special-casing of both DarwinPorts and Fink for darwin since
1315 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1316 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1317 Fink, ``-I/opt/local/include`` for DarwinPorts).
1318
Brett Cannon43802422005-02-10 20:48:03 +00001319- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1320 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1321 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1322 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001324C API
1325-----
1326
Tim Petersc9d78aa2006-03-26 23:27:58 +00001327- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1328 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1329 is obtained via the ``PyObject_`` family, it must be released via the
1330 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1331 always been officially true, but when Python's small-object allocator was
1332 introduced, an attempt was made to cater to a few extension modules
1333 discovered at the time that obtained memory via ``PyObject_New`` but
1334 released it via ``PyMem_DEL``. It's years later, and if such code still
1335 exists it will fail now (probably with segfaults, but calling wrong
1336 low-level memory management functions can yield many symptoms).
1337
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001338- Added a C API for set and frozenset objects.
1339
Raymond Hettinger66517482004-12-03 11:45:13 +00001340- Removed PyRange_New().
1341
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001342- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1343 mapping argument now. This string is used as a mapping table. Byte values
1344 greater than the length of the string and 0xFFFE are treated as undefined
1345 mappings.
