Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
10*Release date: XX-XXX-2006*
11
12Core and builtins
13-----------------
14
Martin v. Löwis45294a92006-04-18 06:24:08 +000015- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
16
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000017- All uses of PyStructSequence_InitType have been changed to initialize
18 the type objects only once, even if the interpreter is initialized
19 multiple times.
20
Neal Norwitz61546162006-04-14 05:20:28 +000021- Bug #1454485, array.array('u') could crash the interpreter. This was
22 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
23 to unicode when it didn't make sense. 'u#' now requires a unicode string.
24
25- Py_UNICODE is unsigned. It was always documented as unsigned, but
26 due to a bug had a signed value in previous versions.
27
Tim Peters3a5e8b12006-04-11 01:44:07 +000028- Patch #837242: ``id()`` of any Python object always gives a positive
29 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
30 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000031 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000032 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000033
Tim Peters3a5e8b12006-04-11 01:44:07 +000034 def __hash__(self):
35 return id(self) # WRONG
36
37 because a hash result must be a (short) Python int but it was always
38 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000039 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000040 was always usable as a hash value before this patch. That's no longer
41 necessarily so.
42
43- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000044 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000045 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000046 #1454844)
47
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000048- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
49 involving generators that have paused outside of any ``try`` or ``with``
50 blocks. (In 2.5a1, a paused generator that was part of a reference
51 cycle could not be garbage collected, regardless of whether it was
52 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000053
Anthony Baxter51bcb682006-04-05 14:51:42 +000054Extension Modules
55-----------------
56
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000057- Patch #1191065: Fix preprocessor problems on systems where recvfrom
58 is a macro.
59
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000060- Bug #1467952: os.listdir() now correctly raises an error if readdir()
61 fails with an error condition.
62
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000063- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
64
65- Bug #1117761: bsddb.*open() no longer raises an exception when using
66 the cachesize parameter.
67
68- Bug #1149413: bsddb.*open() no longer raises an exception when using
69 a temporary db (file=None) with the 'n' flag to truncate on open.
70
71- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
72 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000073
Anthony Baxter51bcb682006-04-05 14:51:42 +000074Library
75-------
76
Tim Petersc7605f22006-04-17 21:12:33 +000077- The ``__del__`` method of class ``local`` in module ``_threading_local``
78 returned before accomplishing any of its intended cleanup.
79
Martin v. Löwisbd30f522006-04-17 17:08:37 +000080- Patch #790710: Add breakpoint command lists in pdb.
81
Martin v. Löwis0db2a982006-04-16 20:55:38 +000082- Patch #1063914: Add Tkinter.Misc.clipboard_get().
83
Martin v. Löwis4b501e62006-04-15 08:41:11 +000084- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
85
Anthony Baxtere29002c2006-04-12 12:07:31 +000086- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
87 Windows. Bug #1469163.
88
Phillip J. Eby47032112006-04-11 01:07:43 +000089- The warnings, linecache, inspect, traceback, site, and doctest modules
90 were updated to work correctly with modules imported from zipfiles or
91 via other PEP 302 __loader__ objects.
92
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000093- Patch #1467770: Reduce usage of subprocess._active to processes which
94 the application hasn't waited on.
95
Martin v. Löwisb04dee92006-04-10 08:34:21 +000096- Patch #1462222: Fix Tix.Grid.
97
Neal Norwitza31bf182006-04-09 03:35:43 +000098- Fix exception when doing glob.glob('anything*/')
99
Anthony Baxter51bcb682006-04-05 14:51:42 +0000100Build
101-----
102
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000103- The Makefile now has a reindent target, which runs reindent.py on
104 the library.
105
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000106- Patch #1470875: Building Python with MS Free Compiler
107
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000108- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000109
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000110- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
111 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000112 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000113 CXX from --with-cxx-main, see description in README.
114
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000115- Patch #1429775: Link extension modules with the shared libpython.

122
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000123- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
124 it separately and by hand. It also wasn't cleaning up its changes to
125 the current Decimal context.

Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000137
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000138Core and builtins
139-----------------
140
Martin v. Löwisea62d252006-04-03 10:56:49 +0000141- Bug #1421664: sys.stderr.encoding is now set to the same value as
142 sys.stdout.encoding.
143
Neal Norwitz92e212f2006-04-03 04:48:37 +0000144- __import__ accepts keyword arguments.
145
Georg Brandlccadf842006-03-31 18:54:53 +0000146- Patch #1460496: round() now accepts keyword arguments.
147
Anthony Baxter262c00a2006-03-30 10:53:17 +0000148- Fixed bug #1459029 - unicode reprs were double-escaped.
149
Hye-Shik Changd478f342006-03-23 12:32:36 +0000150- Patch #1396919: The system scope threads are reenabled on FreeBSD
151 5.4 and later versions.
152
Neal Norwitze98ccf62006-03-23 05:39:47 +0000153- Bug #1115379: Compiling a Unicode string with an encoding declaration
154 now gives a SyntaxError.
155
Georg Brandlabd1ff82006-03-18 07:59:59 +0000156- Previously, Python code had no easy way to access the contents of a
157 cell object. Now, a ``cell_contents`` attribute has been added
158 (closes patch #1170323).
159
Tim Peterscf79aac2006-03-16 01:14:46 +0000160- Patch #1123430: Python's small-object allocator now returns an arena to
161 the system ``free()`` when all memory within an arena becomes unused
162 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
163 freed. Some applications will see a drop in virtual memory size now,
164 especially long-running applications that, from time to time, temporarily
165 use a large number of small objects. Note that when Python returns an
166 arena to the platform C's ``free()``, there's no guarantee that the
167 platform C will in turn return that memory to the operating system. The
168 effect of the patch is to stop making that impossible, and in tests it
169 appears to be effective at least on Microsoft C and gcc-based systems.
170 Thanks to Evan Jones for hard work and patience.
171
Georg Brandl533ff6f2006-03-08 18:09:27 +0000172- Patch #1434038: property() now uses the getter's docstring if there is
173 no "doc" argument given. This makes it possible to legitimately use
174 property() as a decorator to produce a read-only property.
175
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000176- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
177 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
178 of requiring an int or long in slicing and a few other contexts, enabling
179 other objects (e.g. Numeric Python's integers) to be used as slice indices.
180
Neal Norwitz995acdf2006-03-07 05:01:00 +0000181- Fixed various bugs reported by Coverity's Prevent tool.
182
Brett Cannonbf364092006-03-01 04:25:17 +0000183- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
184 new exception base class, BaseException, which has a new message attribute.
185 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
186 Raising a string exception now raises a DeprecationWarning.
187
Thomas Woutersfb609f42006-02-28 16:37:25 +0000188- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
189 explicitly relative, using 'from .module import name' to mean 'from the same
190 package as this module is in. Imports without dots still default to the
191 old relative-then-absolute, unless 'from __future__ import
192 absolute_import' is used.
193
Brett Cannona7446e32006-02-27 23:39:10 +0000194- Properly check if 'warnings' raises an exception (usually when a filter set
195 to "error" is triggered) when raising a warning for raising string
196 exceptions.
197
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000198- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000199 The name was removed from Include/code.h.
200
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000201- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000202
Guido van Rossum1968ad32006-02-25 22:38:04 +0000203- Patch 1433928:
204 - The copy module now "copies" function objects (as atomic objects).
205 - dict.__getitem__ now looks for a __missing__ hook before raising
206 KeyError.
207
Tim Peters84ef21c2006-02-28 20:39:06 +0000208- PEP 343: with statement implemented. Needs ``from __future__ import
209 with_statement``. Use of 'with' as a variable will generate a warning.
210 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000211 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000212 The following objects have __context__ methods:
213 - The built-in file type.
214 - The thread.LockType type.
215 - The following types defined by the threading module:
216 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
217 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000218
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000219- Fix the encodings package codec search function to only search
220 inside its own package. Fixes problem reported in patch #1433198.
221
222 Note: Codec packages should implement and register their own
223 codec search function. PEP 100 has the details.
224
Martin v. Löwis18e16552006-02-15 17:27:45 +0000225- PEP 353: Using ssize_t as the index type.
226
Neal Norwitzfc76d632006-01-10 06:03:13 +0000227- Patch #1400181, fix unicode string formatting to not use the locale.
228 This is how string objects work. u'%f' could use , instead of .
229 for the decimal point. Now both strings and unicode always use periods.
230
Neal Norwitz671b9e32006-01-09 07:07:12 +0000231- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
232 configure would break checking curses.h.
233
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000234- Bug #959576: The pwd module is now builtin. This allows Python to be
235 built on UNIX platforms without $HOME set.
236
Neal Norwitzc10978f2005-12-19 06:07:16 +0000237- Bug #1072182, fix some potential problems if characters are signed.
238
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000239- Bug #889500, fix line number on SyntaxWarning for global declarations.
240
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000241- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
242
Neal Norwitze7214a12005-12-18 05:03:17 +0000243- Support for converting hex strings to floats no longer works.
244 This was not portable. float('0x3') now raises a ValueError.
245
Barry Warsaw2a38a862005-12-18 01:27:35 +0000246- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000247 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000248 is now displayed in interactive prompt banner.
249
Georg Brandlfa166682005-12-17 21:45:17 +0000250- Implementation of PEP 341 - Unification of try/except and try/finally.
251 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000252 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000253
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000254- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
255 now encodes backslash correctly.
256
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000257- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
258
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000259- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000260 and long longs.
261
Neal Norwitz67715f02005-11-09 06:59:35 +0000262- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000263 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000264 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000265
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000266- Replaced most Unicode charmap codecs with new ones using the
267 new Unicode translate string feature in the builtin charmap
268 codec; the codecs were created from the mapping tables available
269 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
270 encodings now include a mapping for the Apple logo)
271
Tim Peterse3547fd2005-12-16 23:13:57 +0000272- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000273
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000274- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000275
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000276- A new AST parser implementation was completed. The abstract
277 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000278 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000279
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000280- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000281 The following code now raises a SyntaxError: foo(a = i for i in range(10))
282
Neal Norwitz708e51a2005-10-03 04:48:15 +0000283- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
284
Neal Norwitz11bd1192005-10-03 00:54:56 +0000285- SF Bug #887946: fix segfault when redirecting stdin from a directory.
286 Provide a warning when a directory is passed on the command line.
287
Neal Norwitz40d37812005-10-02 01:48:49 +0000288- Fix segfault with invalid coding.
289
290- SF bug #772896: unknown encoding results in MemoryError.
291
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000292- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000293 supported a __len__() method which evaluated to False when the iterator
294 was empty.
295
Guido van Rossum630db602005-09-20 18:49:54 +0000296- On 64-bit platforms, when __len__() returns a value that cannot be
297 represented as a C int, raise OverflowError.
298
Skip Montanarof8948ca2005-09-19 03:54:46 +0000299- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000300 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000301
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000302- SF bug #893549: parsing keyword arguments was broken with a few format
303 codes.
304
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000305- Changes donated by Elemental Security to make it work on AIX 5.3
306 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
307 bug #105470: test_pwd fails on 64bit system (Opteron).
308
Guido van Rossum539c6622005-09-14 17:49:54 +0000309- Changes donated by Elemental Security to make it work on HP-UX 11 on
310 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
311
Georg Brandl4550b8d2005-08-26 06:43:52 +0000312- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000313 (fixes bug #1119418).
314
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000315- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
316
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000317- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
318 exceptions that cause a function to exit.
319
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000320- The implementation of set() and frozenset() was revised to use its
321 own internal data structure. Memory consumption is reduced by 1/3
322 and there are modest speed-ups as well. The API is unchanged.
323
Tim Petersde7990b2005-07-17 23:45:23 +0000324- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
325
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000326- SF bug #1229429: PyObject_CallMethod failed to decrement some
327 reference counts in some error exit cases.
328
Tim Petersecc6e6a2005-07-10 22:30:55 +0000329- SF bug #1185883: Python's small-object memory allocator took over
330 a block managed by the platform C library whenever a realloc specified
331 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000332 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000333 portable way to copy data from the C-managed block into Python's
334 small-object space without risking a memory fault. Python's small-object
335 realloc now leaves such blocks under the control of the platform C
336 realloc.
337
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000338- SF bug #1232517: An overflow error was not detected properly when
339 attempting to convert a large float to an int in os.utime().
340
Raymond Hettinger3296e692005-06-29 23:29:56 +0000341- SF bug #1224347: hex longs now print with lowercase letters just
342 like their int counterparts.
343
Michael W. Hudson188d4362005-06-20 16:52:57 +0000344- SF bug #1163563: the original fix for bug #1010677 ("thread Module
345 Breaks PyGILState_Ensure()") broke badly in the case of multiple
346 interpreter states; back out that fix and do a better job (see
347 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
348 for a longer write-up of the problem).
349
Michael W. Hudsondf888462005-06-03 14:41:55 +0000350- SF patch #1180995: marshal now uses a binary format by default when
351 serializing floats.
352
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000353- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
354 the routines that promise to produce IEEE 754 binary representations
355 of floats now simply copy bytes around.
356
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000357- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
358 278.
359
Brett Cannonc3647ac2005-04-26 03:45:26 +0000360- patch #1109424: int, long, float, complex, and unicode now check for the
361 proper magic slot for type conversions when subclassed. Previously the
362 magic slot was ignored during conversion. Semantics now match the way
363 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000364 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000365 PyNumber_*().
366 Thanks Walter Dörwald.
367
Barry Warsawc8d907c2005-04-19 23:43:40 +0000368- Descriptors defined in C with a PyGetSetDef structure, where the setter is
369 NULL, now raise an AttributeError when attempting to set or delete the
370 attribute. Previously a TypeError was raised, but this was inconsistent
371 with the equivalent pure-Python implementation.
372
Michael W. Hudson774479c2005-04-18 08:46:17 +0000373- It is now safe to call PyGILState_Release() before
374 PyEval_InitThreads() (note that if there is reason to believe there
375 are multiple threads around you still must call PyEval_InitThreads()
376 before using the Python API; this fix is for extension modules that
377 have no way of knowing if Python is multi-threaded yet).
378
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000379- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
380 disabled caused a crash.
381
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000382- Bug #1165306: instancemethod_new allowed the creation of a method
383 with im_class == im_self == NULL, which caused a crash when called.
384
Tim Petersecc6e6a2005-07-10 22:30:55 +0000385- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000386 fixes the crash seen in bug #1165761
387
Raymond Hettinger96229b12005-03-11 06:49:40 +0000388- Added two new builtins, any() and all().
389
Brett Cannon409d8f22005-03-05 06:47:57 +0000390- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000391 (e.g., ``class C(): pass`` is no longer a syntax error).
392 Patch #1176012 added support to the 'parser' module and 'compiler' package
393 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000394
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000395- Patch #1115086: Support PY_LONGLONG in structmember.
396
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000397- Bug #1155938: new style classes did not check that __init__() was
398 returning None.
399
Tim Petersecc6e6a2005-07-10 22:30:55 +0000400- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000401 ('\') with a specific error message.
402
Martin v. Löwisff232d72005-03-03 09:24:38 +0000403- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
404
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000405- Bug #1124295: the __name__ attribute of file objects was
406 inadvertently made inaccessible in restricted mode.
407
Tim Petersecc6e6a2005-07-10 22:30:55 +0000408- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000409 an ferror() call.
410
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000411- min() and max() now support key= arguments with the same meaning as in
412 list.sort().
413
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000414- The peephole optimizer now performs simple constant folding in expressions:
415 (2+3) --> (5).
416
Raymond Hettingera422c342005-01-11 03:03:27 +0000417- set and frozenset objects can now be marshalled. SF #1098985.
418
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000419- Bug #1077106: Poor argument checking could cause memory corruption
420 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000421
Jeremy Hyltonab630502005-02-04 18:44:06 +0000422- The parser did not complain about future statements in illegal
423 positions. It once again reports a syntax error if a future
424 statement occurs after anything other than a doc string.
425
Neil Schemenauercf52c072005-08-12 17:34:58 +0000426- Change the %s format specifier for str objects so that it returns a
427 unicode instance if the argument is not an instance of basestring and
428 calling __str__ on the argument returns a unicode instance.
429
Tim Petersf4e69282006-02-27 17:15:31 +0000430- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
431 current thread state when the auto-GIL-state machinery knows about
432 it (since the thread state is being deleted, continuing to remember it
433 can't help, but can hurt if another thread happens to get created with
434 the same thread id).
435
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000436Extension Modules

453
454- The following modules were removed: regsub, reconvert, regex, regex_syntax.
455
456- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000457 is deprecated. The undocumented re.engine variable no longer exists.
458

460 SS2 (single-shift 2) escape sequences correctly.
461
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000462- The unicodedata module was updated to the 4.1 version of the Unicode
463 database. The 3.2 version is still available as unicodedata.db_3_2_0
464 for applications that require this specific version (such as IDNA).
465
Neal Norwitzb62c4332006-03-04 18:35:47 +0000466- The timing module is no longer built by default. It was deprecated
467 in PEP 4 in Python 2.0 or earlier.
468
Guido van Rossum1968ad32006-02-25 22:38:04 +0000469- Patch 1433928: Added a new type, defaultdict, to the collections module.
470 This uses the new __missing__ hook behavior added to dict (see above).
471
Georg Brandldbd83392006-02-20 09:42:33 +0000472- Bug #854823: socketmodule now builds on Sun platforms even when
473 INET_ADDRSTRLEN is not defined.
474
Georg Brandlf4f44152006-02-18 22:29:33 +0000475- Patch #1393157: os.startfile() now has an optional argument to specify
476 a "command verb" to invoke on the file.
477
Neal Norwitz082b2df2006-02-07 07:04:46 +0000478- Bug #876637, prevent stack corruption when socket descriptor

482 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
483 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
484
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000485- Patch #1422385: The nis module now supports access to domains other
486 than the system default domain.
487
Martin v. Löwis14694662006-02-03 12:54:16 +0000488- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
489 are reported, the limit on path name lengths is removed, and stat reports
490 WindowsError now (instead of OSError).
491
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000492- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

634 in attribute values.
635
Anthony Baxterc51ee692006-04-01 00:57:31 +0000636- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000637 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000638 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000639 module will not be built.
640
Tim Petersc17976e2006-04-01 00:26:53 +0000641- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
642 aren't officially supported here, and trying to use them will probably
643 raise an exception some day. But dicts have been allowed, and "mostly
644 worked", so support for them won't go away without warning.
645
Georg Brandl338ef7d2006-03-31 18:42:16 +0000646- Bug #1445068: getpass.getpass() can now be given an explicit stream

648
Georg Brandl22ec80b2006-03-31 18:25:44 +0000649- Patch #1462313, bug #1443328: the pickle modules now can handle classes

656
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000657- Queue.Queue objects now support .task_done() and .join() methods
658 to make it easier to monitor when daemon threads have completed
659 processing all enqueued tasks. Patch #1455676.
660

664
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000665- email 4.0 package now integrated. This is largely the same as the email 3.0
666 package that was included in Python 2.3, except that PEP 8 module names are
667 now used (e.g. mail.message instead of email.Message). The MIME classes
668 have been moved to a subpackage (e.g. email.mime.text instead of
669 email.MIMEText). The old names are still supported for now. Several
670 deprecated Message methods have been removed and lots of bugs have been
671 fixed. More details can be found in the email package documentation.
672
Walter Dörwald40108c92006-03-27 08:15:44 +0000673- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
674 (a subclass of tuple) that provides incremental decoders and encoders
675 (a way to use stateful codecs without the stream API). Python functions
676 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
677 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
678 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000679
Walter Dörwald067db482006-03-15 22:17:27 +0000680- Patch #1359365: Calling next() on a closed StringIO.String object raises
681 a ValueError instead of a StopIteration now (like file and cString.String do).
682 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
683 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000684

759 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
760 Ronald L. Rivest offered this advice for Python:
761
762 "The consensus of researchers in this area (at least as
763 expressed at the NIST Hash Function Workshop 10/31/05),
764 is that SHA-256 is a good choice for the time being, but
765 that research should continue, and other alternatives may
766 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000767

Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000844- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
845 to W3C name (404 -> 'Not Found'). RFE #1216944.
846
Georg Brandl9e43acf2005-07-04 17:16:07 +0000847- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
848 as this can cause problems with apps closing all file descriptors.
849
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000850- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000851 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +0000852

854
Georg Brandlfbff1bc2005-06-26 21:36:25 +0000855- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
856 error messages.
857
Georg Brandl379f99d2005-06-26 21:09:38 +0000858- Bug #1108948: Cookie.py produced invalid JavaScript code.
859
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000860- The tokenize module now detects and reports indentation errors.
861 Bug #1224621.
862
Raymond Hettinger68c04532005-06-10 11:05:19 +0000863- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000864 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000865 the generate_tokens() function now accepts a callable argument that
866 terminates by raising StopIteration.
867
Georg Brandl9166e1a2005-06-04 09:20:03 +0000868- Bug #1196315: fix weakref.WeakValueDictionary constructor.
869
Georg Brandl268e61c2005-06-03 14:28:50 +0000870- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
871 component of the path.
872
Skip Montanaro174dd222005-05-14 20:54:16 +0000873- Patch #1120353: The xmlrpclib module provides better, more transparent,
874 support for datetime.{datetime,date,time} objects. With use_datetime set
875 to True, applications shouldn't have to fiddle with the DateTime wrapper
876 class at all.
877
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000878- distutils.commands.upload was added to support uploading distribution
879 files to PyPI.
880
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000881- distutils.commands.register now encodes the data as UTF-8 before posting
882 them to PyPI.
883
Raymond Hettinger267b8682005-03-27 10:47:39 +0000884- decimal operator and comparison methods now return NotImplemented
885 instead of raising a TypeError when interacting with other types. This
886 allows other classes to implement __radd__ style methods and have them
887 work as expected.
888
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000889- Bug #1163325: Decimal infinities failed to hash. Attempting to
890 hash a NaN raised an InvalidOperation instead of a TypeError.
891
Tim Petersecc6e6a2005-07-10 22:30:55 +0000892- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000893 stream compression; add, for symmetry reasons, r:* as a synonym of r.
894
Martin v. Löwis00a73e72005-03-04 19:40:34 +0000895- Patch #1043890: Add extractall method to tarfile.
896
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000897- Patch #1075887: Don't require MSVC in distutils if there is nothing
898 to build.
899
Martin v. Löwis637431b2005-03-03 23:12:42 +0000900- Patch #1103407: Properly deal with tarfile iterators when untarring
901 symbolic links on Windows.
902
Tim Petersecc6e6a2005-07-10 22:30:55 +0000903- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000904 profile.py if available.
905
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +0000906- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
907
Martin v. Löwisc5574e82005-03-03 10:57:37 +0000908- Patch #1117454: Remove code to special-case cookies without values
909 in LWPCookieJar.
910
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +0000911- Patch #1117339: Add cookielib special name tests.

916
Martin v. Löwisdf241532005-03-03 08:17:42 +0000917- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
918
Martin v. Löwis8ed338a2005-03-03 08:12:27 +0000919- Patch #1104111: Alter setup.py --help and --help-commands.
920
Martin v. Löwis4afe1542005-03-01 08:09:28 +0000921- Patch #1121234: Properly cleanup _exit and tkerror commands.
922
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +0000923- Patch #1049151: xdrlib now unpacks booleans as True or False.
924
Raymond Hettingerbab41432005-02-05 01:31:19 +0000925- Fixed bug in a NameError bug in cookielib. Patch #1116583.
926
Guido van Rossumd0641422005-02-03 15:01:24 +0000927- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
928 disables recursive traversal through instance attributes, which can
929 be exploited in various ways.
930
Tim Peterse3547fd2005-12-16 23:13:57 +0000931- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000932 flags on the HTTP listening socket.
933
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000934- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
935 Fixed by reading the HTTP body in chunks instead of one big socket.read().
936
Tim Peterse3547fd2005-12-16 23:13:57 +0000937- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000938 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
939

943
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000944- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
945
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000946- Enhancements to the csv module:
947
948 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000949 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000950 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000951 + Dialect parameter parsing has been re-implemented to improve error
952 reporting.
953 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
954 dictates.
955 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000956 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +0000957 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000958 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
959 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000960 + reader now allows \r characters to be quoted (previously it only allowed
961 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000962 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000963 + Dialect classes passed to the module are no longer instantiated by
964 the module before being parsed (the former validation scheme required
965 this, but the mechanism was unreliable).
966 + The dialect registry now contains instances of the internal
967 C-coded dialect type, rather than references to python objects.
968 + the internal c-coded dialect type is now immutable.
969 + register_dialect now accepts the same keyword dialect specifications
970 as the reader and writer, allowing the user to register dialects
971 without first creating a dialect class.
972 + a configurable limit to the size of parsed fields has been added -
973 previously, an unmatched quote character could result in the entire
974 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000975 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000976 the parser field size limit (returning the former limit). The initial
977 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000978 + A line_num attribute has been added to the reader object, which tracks
979 the number of lines read from the source iterator. This is not
980 the same as the number of records returned, as records can span
981 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000982 + reader and writer objects were not being registered with the cyclic-GC.
983 This has been fixed.
984
Brett Cannone6539c42005-01-08 02:43:53 +0000985- _DummyThread objects in the threading module now delete self.__block that is
986 inherited from _Thread since it uses up a lock allocated by 'thread'. The
987 lock primitives tend to be limited in number and thus should not be wasted on
988 a _DummyThread object. Fixes bug #1089632.
989
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000990- The imghdr module now detects Exif files.
991
Raymond Hettinger6065d322004-12-20 23:51:53 +0000992- StringIO.truncate() now correctly adjusts the size attribute.
993 (Bug #951915).
994
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000995- locale.py now uses an updated locale alias table (built using
996 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
997 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000998 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000999
Raymond Hettinger3557f422004-12-07 12:02:02 +00001000- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1001
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001002- the pickle module no longer accepts the deprecated None option in the
1003 args tuple returned by __reduce__().
1004
Brett Cannon84667c02004-12-07 03:25:18 +00001005- optparse now optionally imports gettext. This allows its use in setup.py.
1006
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001007- the pickle module no longer uses the deprecated bin parameter.
1008
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001009- the shelve module no longer uses the deprecated binary parameter.
1010
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001011- the pstats module no longer uses the deprecated ignore() method.
1012
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001013- the filecmp module no longer uses the deprecated use_statcache argument.
1014
Raymond Hettinger664347b2004-12-04 21:21:53 +00001015- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1016 extended or overridden by subclasses. Formerly, the subclassed method would
1017 be ignored by the rest of the module. (Bug #1078905).
1018
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001019- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001020 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001021
Walter Dörwald36733692004-12-22 12:50:50 +00001022- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1023 once when a size argument is given. This prevents a buffer overflow in the
1024 tokenizer with very long source lines.
1025
Barry Warsaw538561e2006-01-01 21:48:54 +00001026- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1027 immediately after creating the object, without any intervening
1028 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001029
Skip Montanaro05885812005-01-16 20:48:27 +00001030- The reconvert.quote function can now emit triple-quoted strings. The
1031 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001032
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001033- ``UserString.MutableString`` now supports negative indices in
1034 ``__setitem__`` and ``__delitem__``
1035
Greg Ward40407942005-03-05 02:53:17 +00001036- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1037 correctly.
1038
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001039- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1040 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1041 character even if the user has passed a size parameter to get a proper
1042 line ending. Remove the special handling of a "\r\n" that has been split
1043 between two lines.
1044
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001045- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1046 about illegal code points. The codec now supports PEP 293 style error
1047 handlers.
1048
Walter Dörwald78a78b02005-09-01 12:04:29 +00001049- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001050 from the input stream, so that the output is a byte string in the correct
1051 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001052
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001053- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1054 considering it exactly like a '*'.
1055
Walter Dörwald007f8df2005-10-09 19:42:27 +00001056- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1057 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001058
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001059- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1060
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001061- Patch #1413711: Certain patterns of differences were making difflib
1062 touch the recursion limit.
1063
Walter Dörwald58917a62006-03-31 15:26:22 +00001064- Bug #947906: An object oriented interface has been added to the calendar
1065 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001066 called as a script (e.g. via ``python -mcalendar``). Localized month and
1067 weekday names can be ouput (even if an exotic encoding is used) using
1068 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001069

1093 vulnerability in zlib 1.2.1 and 1.2.2.
1094
Brett Cannon08cd5982005-04-24 22:26:38 +00001095- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1096 flags that change binary compatibility. Changes were also made to
1097 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001098 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001099
Bob Ippolitoed233462005-03-29 13:47:59 +00001100- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1101 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1102 no longer exists). This configure patch makes things right.
1103
Martin v. Löwise2713be2005-03-08 15:03:08 +00001104- Bug #1158607: Build with --disable-unicode again.
1105
Brett Cannon46d96232005-02-16 00:07:19 +00001106- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is

Brett Cannon516592f2004-12-07 00:42:59 +00001109- setup.py now uses the directories specified in LDFLAGS using the -L option
1110 and in CPPFLAGS using the -I option for adding library and include
1111 directories, respectively, for compiling extension modules against. This has
1112 led to the core being compiled using the values in CPPFLAGS. It also removes
1113 the need for the special-casing of both DarwinPorts and Fink for darwin since
1114 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1115 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1116 Fink, ``-I/opt/local/include`` for DarwinPorts).
1117
Brett Cannon43802422005-02-10 20:48:03 +00001118- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1119 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1120 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1121 Closes bug #1096244. Thanks Gregory Bond.

1125
Tim Petersc9d78aa2006-03-26 23:27:58 +00001126- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1127 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1128 is obtained via the ``PyObject_`` family, it must be released via the
1129 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1130 always been officially true, but when Python's small-object allocator was
1131 introduced, an attempt was made to cater to a few extension modules
1132 discovered at the time that obtained memory via ``PyObject_New`` but
1133 released it via ``PyMem_DEL``. It's years later, and if such code still
1134 exists it will fail now (probably with segfaults, but calling wrong
1135 low-level memory management functions can yield many symptoms).
1136
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001137- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001141- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1142 mapping argument now. This string is used as a mapping table. Byte values
1143 greater than the length of the string and 0xFFFE are treated as undefined
1144 mappings.
