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. Löwis19ab6c92006-04-16 18:55:50 +000015- All uses of PyStructSequence_InitType have been changed to initialize
16 the type objects only once, even if the interpreter is initialized
17 multiple times.
18
Neal Norwitz61546162006-04-14 05:20:28 +000019- Bug #1454485, array.array('u') could crash the interpreter. This was
20 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
21 to unicode when it didn't make sense. 'u#' now requires a unicode string.
22
23- Py_UNICODE is unsigned. It was always documented as unsigned, but
24 due to a bug had a signed value in previous versions.
25
Tim Peters3a5e8b12006-04-11 01:44:07 +000026- Patch #837242: ``id()`` of any Python object always gives a positive
27 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
28 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000029 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000030 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000031
Tim Peters3a5e8b12006-04-11 01:44:07 +000032 def __hash__(self):
33 return id(self) # WRONG
34
35 because a hash result must be a (short) Python int but it was always
36 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000037 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000038 was always usable as a hash value before this patch. That's no longer
39 necessarily so.
40
41- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000042 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000043 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000044 #1454844)
45
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000046- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
47 involving generators that have paused outside of any ``try`` or ``with``
48 blocks. (In 2.5a1, a paused generator that was part of a reference
49 cycle could not be garbage collected, regardless of whether it was
50 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000051
Anthony Baxter51bcb682006-04-05 14:51:42 +000052Extension Modules
53-----------------
54
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000055- Patch #1191065: Fix preprocessor problems on systems where recvfrom
56 is a macro.
57
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000058- Bug #1467952: os.listdir() now correctly raises an error if readdir()
59 fails with an error condition.
60
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000061- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
62
63- Bug #1117761: bsddb.*open() no longer raises an exception when using
64 the cachesize parameter.
65
66- Bug #1149413: bsddb.*open() no longer raises an exception when using
67 a temporary db (file=None) with the 'n' flag to truncate on open.
68
69- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
70 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000071
Anthony Baxter51bcb682006-04-05 14:51:42 +000072Library
73-------
74
Tim Petersc7605f22006-04-17 21:12:33 +000075- The ``__del__`` method of class ``local`` in module ``_threading_local``
76 returned before accomplishing any of its intended cleanup.
77
Martin v. Löwisbd30f522006-04-17 17:08:37 +000078- Patch #790710: Add breakpoint command lists in pdb.
79
Martin v. Löwis0db2a982006-04-16 20:55:38 +000080- Patch #1063914: Add Tkinter.Misc.clipboard_get().
81
Martin v. Löwis4b501e62006-04-15 08:41:11 +000082- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
83
Anthony Baxtere29002c2006-04-12 12:07:31 +000084- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
85 Windows. Bug #1469163.
86
Phillip J. Eby47032112006-04-11 01:07:43 +000087- The warnings, linecache, inspect, traceback, site, and doctest modules
88 were updated to work correctly with modules imported from zipfiles or
89 via other PEP 302 __loader__ objects.
90
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000091- Patch #1467770: Reduce usage of subprocess._active to processes which
92 the application hasn't waited on.
93
Martin v. Löwisb04dee92006-04-10 08:34:21 +000094- Patch #1462222: Fix Tix.Grid.
95
Neal Norwitza31bf182006-04-09 03:35:43 +000096- Fix exception when doing glob.glob('anything*/')
97
Anthony Baxter51bcb682006-04-05 14:51:42 +000098Build
99-----
100
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000101- The Makefile now has a reindent target, which runs reindent.py on
102 the library.
103
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000104- Patch #1470875: Building Python with MS Free Compiler
105
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000106- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000107
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000108- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
109 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000110 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000111 CXX from --with-cxx-main, see description in README.
112
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000113- Patch #1429775: Link extension modules with the shared libpython.

120
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000121- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
122 it separately and by hand. It also wasn't cleaning up its changes to
123 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000136Core and builtins
137-----------------
138
Martin v. Löwisea62d252006-04-03 10:56:49 +0000139- Bug #1421664: sys.stderr.encoding is now set to the same value as
140 sys.stdout.encoding.
141
Neal Norwitz92e212f2006-04-03 04:48:37 +0000142- __import__ accepts keyword arguments.
143
Georg Brandlccadf842006-03-31 18:54:53 +0000144- Patch #1460496: round() now accepts keyword arguments.
145
Anthony Baxter262c00a2006-03-30 10:53:17 +0000146- Fixed bug #1459029 - unicode reprs were double-escaped.
147
Hye-Shik Changd478f342006-03-23 12:32:36 +0000148- Patch #1396919: The system scope threads are reenabled on FreeBSD
149 5.4 and later versions.
150
Neal Norwitze98ccf62006-03-23 05:39:47 +0000151- Bug #1115379: Compiling a Unicode string with an encoding declaration
152 now gives a SyntaxError.
153
Georg Brandlabd1ff82006-03-18 07:59:59 +0000154- Previously, Python code had no easy way to access the contents of a
155 cell object. Now, a ``cell_contents`` attribute has been added
156 (closes patch #1170323).
157
Tim Peterscf79aac2006-03-16 01:14:46 +0000158- Patch #1123430: Python's small-object allocator now returns an arena to
159 the system ``free()`` when all memory within an arena becomes unused
160 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
161 freed. Some applications will see a drop in virtual memory size now,
162 especially long-running applications that, from time to time, temporarily
163 use a large number of small objects. Note that when Python returns an
164 arena to the platform C's ``free()``, there's no guarantee that the
165 platform C will in turn return that memory to the operating system. The
166 effect of the patch is to stop making that impossible, and in tests it
167 appears to be effective at least on Microsoft C and gcc-based systems.
168 Thanks to Evan Jones for hard work and patience.
169
Georg Brandl533ff6f2006-03-08 18:09:27 +0000170- Patch #1434038: property() now uses the getter's docstring if there is
171 no "doc" argument given. This makes it possible to legitimately use
172 property() as a decorator to produce a read-only property.
173
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000174- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
175 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
176 of requiring an int or long in slicing and a few other contexts, enabling
177 other objects (e.g. Numeric Python's integers) to be used as slice indices.
178
Neal Norwitz995acdf2006-03-07 05:01:00 +0000179- Fixed various bugs reported by Coverity's Prevent tool.
180
Brett Cannonbf364092006-03-01 04:25:17 +0000181- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
182 new exception base class, BaseException, which has a new message attribute.
183 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
184 Raising a string exception now raises a DeprecationWarning.
185
Thomas Woutersfb609f42006-02-28 16:37:25 +0000186- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
187 explicitly relative, using 'from .module import name' to mean 'from the same
188 package as this module is in. Imports without dots still default to the
189 old relative-then-absolute, unless 'from __future__ import
190 absolute_import' is used.
191
Brett Cannona7446e32006-02-27 23:39:10 +0000192- Properly check if 'warnings' raises an exception (usually when a filter set
193 to "error" is triggered) when raising a warning for raising string
194 exceptions.
195
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000196- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000197 The name was removed from Include/code.h.
198
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000199- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000200
Guido van Rossum1968ad32006-02-25 22:38:04 +0000201- Patch 1433928:
202 - The copy module now "copies" function objects (as atomic objects).
203 - dict.__getitem__ now looks for a __missing__ hook before raising
204 KeyError.
205
Tim Peters84ef21c2006-02-28 20:39:06 +0000206- PEP 343: with statement implemented. Needs ``from __future__ import
207 with_statement``. Use of 'with' as a variable will generate a warning.
208 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000209 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000210 The following objects have __context__ methods:
211 - The built-in file type.
212 - The thread.LockType type.
213 - The following types defined by the threading module:
214 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
215 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000216
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000217- Fix the encodings package codec search function to only search
218 inside its own package. Fixes problem reported in patch #1433198.
219
220 Note: Codec packages should implement and register their own
221 codec search function. PEP 100 has the details.
222
Martin v. Löwis18e16552006-02-15 17:27:45 +0000223- PEP 353: Using ssize_t as the index type.
224
Neal Norwitzfc76d632006-01-10 06:03:13 +0000225- Patch #1400181, fix unicode string formatting to not use the locale.
226 This is how string objects work. u'%f' could use , instead of .
227 for the decimal point. Now both strings and unicode always use periods.
228
Neal Norwitz671b9e32006-01-09 07:07:12 +0000229- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
230 configure would break checking curses.h.
231
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000232- Bug #959576: The pwd module is now builtin. This allows Python to be
233 built on UNIX platforms without $HOME set.
234
Neal Norwitzc10978f2005-12-19 06:07:16 +0000235- Bug #1072182, fix some potential problems if characters are signed.
236
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000237- Bug #889500, fix line number on SyntaxWarning for global declarations.
238
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000239- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
240
Neal Norwitze7214a12005-12-18 05:03:17 +0000241- Support for converting hex strings to floats no longer works.
242 This was not portable. float('0x3') now raises a ValueError.
243
Barry Warsaw2a38a862005-12-18 01:27:35 +0000244- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000245 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000246 is now displayed in interactive prompt banner.
247
Georg Brandlfa166682005-12-17 21:45:17 +0000248- Implementation of PEP 341 - Unification of try/except and try/finally.
249 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000250 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000251
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000252- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
253 now encodes backslash correctly.
254
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000255- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
256
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000257- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000258 and long longs.
259
Neal Norwitz67715f02005-11-09 06:59:35 +0000260- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000261 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000262 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000263
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000264- Replaced most Unicode charmap codecs with new ones using the
265 new Unicode translate string feature in the builtin charmap
266 codec; the codecs were created from the mapping tables available
267 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
268 encodings now include a mapping for the Apple logo)
269
Tim Peterse3547fd2005-12-16 23:13:57 +0000270- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000271
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000272- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000273
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000274- A new AST parser implementation was completed. The abstract
275 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000276 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000277
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000278- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000279 The following code now raises a SyntaxError: foo(a = i for i in range(10))
280
Neal Norwitz708e51a2005-10-03 04:48:15 +0000281- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
282
Neal Norwitz11bd1192005-10-03 00:54:56 +0000283- SF Bug #887946: fix segfault when redirecting stdin from a directory.
284 Provide a warning when a directory is passed on the command line.
285
Neal Norwitz40d37812005-10-02 01:48:49 +0000286- Fix segfault with invalid coding.
287
288- SF bug #772896: unknown encoding results in MemoryError.
289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000290- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000291 supported a __len__() method which evaluated to False when the iterator
292 was empty.
293
Guido van Rossum630db602005-09-20 18:49:54 +0000294- On 64-bit platforms, when __len__() returns a value that cannot be
295 represented as a C int, raise OverflowError.
296
Skip Montanarof8948ca2005-09-19 03:54:46 +0000297- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000298 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000299
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000300- SF bug #893549: parsing keyword arguments was broken with a few format
301 codes.
302
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000303- Changes donated by Elemental Security to make it work on AIX 5.3
304 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
305 bug #105470: test_pwd fails on 64bit system (Opteron).
306
Guido van Rossum539c6622005-09-14 17:49:54 +0000307- Changes donated by Elemental Security to make it work on HP-UX 11 on
308 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
309
Georg Brandl4550b8d2005-08-26 06:43:52 +0000310- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000311 (fixes bug #1119418).
312
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000313- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
314
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000315- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
316 exceptions that cause a function to exit.
317
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000318- The implementation of set() and frozenset() was revised to use its
319 own internal data structure. Memory consumption is reduced by 1/3
320 and there are modest speed-ups as well. The API is unchanged.
321
Tim Petersde7990b2005-07-17 23:45:23 +0000322- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
323
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000324- SF bug #1229429: PyObject_CallMethod failed to decrement some
325 reference counts in some error exit cases.
326
Tim Petersecc6e6a2005-07-10 22:30:55 +0000327- SF bug #1185883: Python's small-object memory allocator took over
328 a block managed by the platform C library whenever a realloc specified
329 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000330 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000331 portable way to copy data from the C-managed block into Python's
332 small-object space without risking a memory fault. Python's small-object
333 realloc now leaves such blocks under the control of the platform C
334 realloc.
335
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000336- SF bug #1232517: An overflow error was not detected properly when
337 attempting to convert a large float to an int in os.utime().
338
Raymond Hettinger3296e692005-06-29 23:29:56 +0000339- SF bug #1224347: hex longs now print with lowercase letters just
340 like their int counterparts.
341
Michael W. Hudson188d4362005-06-20 16:52:57 +0000342- SF bug #1163563: the original fix for bug #1010677 ("thread Module
343 Breaks PyGILState_Ensure()") broke badly in the case of multiple
344 interpreter states; back out that fix and do a better job (see
345 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
346 for a longer write-up of the problem).
347
Michael W. Hudsondf888462005-06-03 14:41:55 +0000348- SF patch #1180995: marshal now uses a binary format by default when
349 serializing floats.
350
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000351- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
352 the routines that promise to produce IEEE 754 binary representations
353 of floats now simply copy bytes around.
354
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000355- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
356 278.
357
Brett Cannonc3647ac2005-04-26 03:45:26 +0000358- patch #1109424: int, long, float, complex, and unicode now check for the
359 proper magic slot for type conversions when subclassed. Previously the
360 magic slot was ignored during conversion. Semantics now match the way
361 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000362 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000363 PyNumber_*().
364 Thanks Walter Dörwald.
365
Barry Warsawc8d907c2005-04-19 23:43:40 +0000366- Descriptors defined in C with a PyGetSetDef structure, where the setter is
367 NULL, now raise an AttributeError when attempting to set or delete the
368 attribute. Previously a TypeError was raised, but this was inconsistent
369 with the equivalent pure-Python implementation.
370
Michael W. Hudson774479c2005-04-18 08:46:17 +0000371- It is now safe to call PyGILState_Release() before
372 PyEval_InitThreads() (note that if there is reason to believe there
373 are multiple threads around you still must call PyEval_InitThreads()
374 before using the Python API; this fix is for extension modules that
375 have no way of knowing if Python is multi-threaded yet).
376
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000377- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
378 disabled caused a crash.
379
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000380- Bug #1165306: instancemethod_new allowed the creation of a method
381 with im_class == im_self == NULL, which caused a crash when called.
382
Tim Petersecc6e6a2005-07-10 22:30:55 +0000383- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000384 fixes the crash seen in bug #1165761
385
Raymond Hettinger96229b12005-03-11 06:49:40 +0000386- Added two new builtins, any() and all().
387
Brett Cannon409d8f22005-03-05 06:47:57 +0000388- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000389 (e.g., ``class C(): pass`` is no longer a syntax error).
390 Patch #1176012 added support to the 'parser' module and 'compiler' package
391 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000392
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000393- Patch #1115086: Support PY_LONGLONG in structmember.
394
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000395- Bug #1155938: new style classes did not check that __init__() was
396 returning None.
397
Tim Petersecc6e6a2005-07-10 22:30:55 +0000398- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000399 ('\') with a specific error message.
400
Martin v. Löwisff232d72005-03-03 09:24:38 +0000401- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
402
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000403- Bug #1124295: the __name__ attribute of file objects was
404 inadvertently made inaccessible in restricted mode.
405
Tim Petersecc6e6a2005-07-10 22:30:55 +0000406- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000407 an ferror() call.
408
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000409- min() and max() now support key= arguments with the same meaning as in
410 list.sort().
411
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000412- The peephole optimizer now performs simple constant folding in expressions:
413 (2+3) --> (5).
414
Raymond Hettingera422c342005-01-11 03:03:27 +0000415- set and frozenset objects can now be marshalled. SF #1098985.
416
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000417- Bug #1077106: Poor argument checking could cause memory corruption
418 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000419
Jeremy Hyltonab630502005-02-04 18:44:06 +0000420- The parser did not complain about future statements in illegal
421 positions. It once again reports a syntax error if a future
422 statement occurs after anything other than a doc string.
423
Neil Schemenauercf52c072005-08-12 17:34:58 +0000424- Change the %s format specifier for str objects so that it returns a
425 unicode instance if the argument is not an instance of basestring and
426 calling __str__ on the argument returns a unicode instance.
427
Tim Petersf4e69282006-02-27 17:15:31 +0000428- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
429 current thread state when the auto-GIL-state machinery knows about
430 it (since the thread state is being deleted, continuing to remember it
431 can't help, but can hurt if another thread happens to get created with
432 the same thread id).
433
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000434Extension Modules

451
452- The following modules were removed: regsub, reconvert, regex, regex_syntax.
453
454- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000455 is deprecated. The undocumented re.engine variable no longer exists.
456

458 SS2 (single-shift 2) escape sequences correctly.
459
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000460- The unicodedata module was updated to the 4.1 version of the Unicode
461 database. The 3.2 version is still available as unicodedata.db_3_2_0
462 for applications that require this specific version (such as IDNA).
463
Neal Norwitzb62c4332006-03-04 18:35:47 +0000464- The timing module is no longer built by default. It was deprecated
465 in PEP 4 in Python 2.0 or earlier.
466
Guido van Rossum1968ad32006-02-25 22:38:04 +0000467- Patch 1433928: Added a new type, defaultdict, to the collections module.
468 This uses the new __missing__ hook behavior added to dict (see above).
469
Georg Brandldbd83392006-02-20 09:42:33 +0000470- Bug #854823: socketmodule now builds on Sun platforms even when
471 INET_ADDRSTRLEN is not defined.
472
Georg Brandlf4f44152006-02-18 22:29:33 +0000473- Patch #1393157: os.startfile() now has an optional argument to specify
474 a "command verb" to invoke on the file.
475
Neal Norwitz082b2df2006-02-07 07:04:46 +0000476- Bug #876637, prevent stack corruption when socket descriptor

480 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
481 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
482
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000483- Patch #1422385: The nis module now supports access to domains other
484 than the system default domain.
485
Martin v. Löwis14694662006-02-03 12:54:16 +0000486- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
487 are reported, the limit on path name lengths is removed, and stat reports
488 WindowsError now (instead of OSError).
489
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000490- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

610
Raymond Hettingerb2594052004-12-05 09:25:51 +0000611- itertools.islice() now accepts None for the start and step arguments.
612 This allows islice() to work more readily with slices:

632 in attribute values.
633
Anthony Baxterc51ee692006-04-01 00:57:31 +0000634- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000635 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000636 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000637 module will not be built.
638
Tim Petersc17976e2006-04-01 00:26:53 +0000639- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
640 aren't officially supported here, and trying to use them will probably
641 raise an exception some day. But dicts have been allowed, and "mostly
642 worked", so support for them won't go away without warning.
643
Georg Brandl338ef7d2006-03-31 18:42:16 +0000644- Bug #1445068: getpass.getpass() can now be given an explicit stream

646
Georg Brandl22ec80b2006-03-31 18:25:44 +0000647- Patch #1462313, bug #1443328: the pickle modules now can handle classes

653 key to be used for signing the uploaded code.
654
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000655- Queue.Queue objects now support .task_done() and .join() methods
656 to make it easier to monitor when daemon threads have completed
657 processing all enqueued tasks. Patch #1455676.
658
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000659- popen2.Popen objects now preserve the command in a .cmd attribute.

662
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000663- email 4.0 package now integrated. This is largely the same as the email 3.0
664 package that was included in Python 2.3, except that PEP 8 module names are
665 now used (e.g. mail.message instead of email.Message). The MIME classes
666 have been moved to a subpackage (e.g. email.mime.text instead of
667 email.MIMEText). The old names are still supported for now. Several
668 deprecated Message methods have been removed and lots of bugs have been
669 fixed. More details can be found in the email package documentation.
670
Walter Dörwald40108c92006-03-27 08:15:44 +0000671- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
672 (a subclass of tuple) that provides incremental decoders and encoders
673 (a way to use stateful codecs without the stream API). Python functions
674 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
675 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
676 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000677
Walter Dörwald067db482006-03-15 22:17:27 +0000678- Patch #1359365: Calling next() on a closed StringIO.String object raises
679 a ValueError instead of a StopIteration now (like file and cString.String do).
680 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
681 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000682

759
760 "The consensus of researchers in this area (at least as
761 expressed at the NIST Hash Function Workshop 10/31/05),
762 is that SHA-256 is a good choice for the time being, but
763 that research should continue, and other alternatives may
764 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000765

Georg Brandl9e43acf2005-07-04 17:16:07 +0000845- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
846 as this can cause problems with apps closing all file descriptors.
847
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000848- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000849 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +0000850
Georg Brandl2f210b62005-06-26 22:09:06 +0000851- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
852
Georg Brandlfbff1bc2005-06-26 21:36:25 +0000853- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
854 error messages.
855
Georg Brandl379f99d2005-06-26 21:09:38 +0000856- Bug #1108948: Cookie.py produced invalid JavaScript code.
857
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000858- The tokenize module now detects and reports indentation errors.
859 Bug #1224621.
860
Raymond Hettinger68c04532005-06-10 11:05:19 +0000861- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000862 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000863 the generate_tokens() function now accepts a callable argument that
864 terminates by raising StopIteration.
865
Georg Brandl9166e1a2005-06-04 09:20:03 +0000866- Bug #1196315: fix weakref.WeakValueDictionary constructor.
867
Georg Brandl268e61c2005-06-03 14:28:50 +0000868- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
869 component of the path.
870
Skip Montanaro174dd222005-05-14 20:54:16 +0000871- Patch #1120353: The xmlrpclib module provides better, more transparent,
872 support for datetime.{datetime,date,time} objects. With use_datetime set
873 to True, applications shouldn't have to fiddle with the DateTime wrapper
874 class at all.
875
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000876- distutils.commands.upload was added to support uploading distribution
877 files to PyPI.
878
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000879- distutils.commands.register now encodes the data as UTF-8 before posting
880 them to PyPI.
881
Raymond Hettinger267b8682005-03-27 10:47:39 +0000882- decimal operator and comparison methods now return NotImplemented
883 instead of raising a TypeError when interacting with other types. This
884 allows other classes to implement __radd__ style methods and have them
885 work as expected.
886
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000887- Bug #1163325: Decimal infinities failed to hash. Attempting to
888 hash a NaN raised an InvalidOperation instead of a TypeError.
889
Tim Petersecc6e6a2005-07-10 22:30:55 +0000890- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000891 stream compression; add, for symmetry reasons, r:* as a synonym of r.
892

894
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000895- Patch #1075887: Don't require MSVC in distutils if there is nothing
896 to build.
897
Martin v. Löwis637431b2005-03-03 23:12:42 +0000898- Patch #1103407: Properly deal with tarfile iterators when untarring
899 symbolic links on Windows.
900
Tim Petersecc6e6a2005-07-10 22:30:55 +0000901- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000902 profile.py if available.

922
Raymond Hettingerbab41432005-02-05 01:31:19 +0000923- Fixed bug in a NameError bug in cookielib. Patch #1116583.
924
Guido van Rossumd0641422005-02-03 15:01:24 +0000925- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
926 disables recursive traversal through instance attributes, which can
927 be exploited in various ways.
928
Tim Peterse3547fd2005-12-16 23:13:57 +0000929- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000930 flags on the HTTP listening socket.
931
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000932- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
933 Fixed by reading the HTTP body in chunks instead of one big socket.read().
934
Tim Peterse3547fd2005-12-16 23:13:57 +0000935- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000936 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
937
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000938- Bug #1110478: Revert os.environ.update to do putenv again.
939

941
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000942- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
943
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000944- Enhancements to the csv module:
945
946 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000947 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000948 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000949 + Dialect parameter parsing has been re-implemented to improve error
950 reporting.
951 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
952 dictates.
953 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000954 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000955 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000956 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
957 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000958 + reader now allows \r characters to be quoted (previously it only allowed
959 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000960 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000961 + Dialect classes passed to the module are no longer instantiated by
962 the module before being parsed (the former validation scheme required
963 this, but the mechanism was unreliable).
964 + The dialect registry now contains instances of the internal
965 C-coded dialect type, rather than references to python objects.
966 + the internal c-coded dialect type is now immutable.
967 + register_dialect now accepts the same keyword dialect specifications
968 as the reader and writer, allowing the user to register dialects
969 without first creating a dialect class.
970 + a configurable limit to the size of parsed fields has been added -
971 previously, an unmatched quote character could result in the entire
972 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000973 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000974 the parser field size limit (returning the former limit). The initial
975 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000976 + A line_num attribute has been added to the reader object, which tracks
977 the number of lines read from the source iterator. This is not
978 the same as the number of records returned, as records can span
979 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000980 + reader and writer objects were not being registered with the cyclic-GC.
981 This has been fixed.
982
Brett Cannone6539c42005-01-08 02:43:53 +0000983- _DummyThread objects in the threading module now delete self.__block that is
984 inherited from _Thread since it uses up a lock allocated by 'thread'. The
985 lock primitives tend to be limited in number and thus should not be wasted on
986 a _DummyThread object. Fixes bug #1089632.
987
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000988- The imghdr module now detects Exif files.
989
Raymond Hettinger6065d322004-12-20 23:51:53 +0000990- StringIO.truncate() now correctly adjusts the size attribute.
991 (Bug #951915).
992
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000993- locale.py now uses an updated locale alias table (built using
994 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
995 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000996 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000997
Raymond Hettinger3557f422004-12-07 12:02:02 +0000998- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
999
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001000- the pickle module no longer accepts the deprecated None option in the
1001 args tuple returned by __reduce__().
1002
Brett Cannon84667c02004-12-07 03:25:18 +00001003- optparse now optionally imports gettext. This allows its use in setup.py.
1004
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001005- the pickle module no longer uses the deprecated bin parameter.
1006
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001007- the shelve module no longer uses the deprecated binary parameter.
1008
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001009- the pstats module no longer uses the deprecated ignore() method.
1010
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001011- the filecmp module no longer uses the deprecated use_statcache argument.
1012
Raymond Hettinger664347b2004-12-04 21:21:53 +00001013- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1014 extended or overridden by subclasses. Formerly, the subclassed method would
1015 be ignored by the rest of the module. (Bug #1078905).
1016
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001017- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001018 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001019
Walter Dörwald36733692004-12-22 12:50:50 +00001020- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1021 once when a size argument is given. This prevents a buffer overflow in the
1022 tokenizer with very long source lines.
1023
Barry Warsaw538561e2006-01-01 21:48:54 +00001024- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1025 immediately after creating the object, without any intervening
1026 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001027
Skip Montanaro05885812005-01-16 20:48:27 +00001028- The reconvert.quote function can now emit triple-quoted strings. The
1029 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001030
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001031- ``UserString.MutableString`` now supports negative indices in
1032 ``__setitem__`` and ``__delitem__``
1033
Greg Ward40407942005-03-05 02:53:17 +00001034- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1035 correctly.
1036
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001037- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1038 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1039 character even if the user has passed a size parameter to get a proper
1040 line ending. Remove the special handling of a "\r\n" that has been split
1041 between two lines.
1042
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001043- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1044 about illegal code points. The codec now supports PEP 293 style error
1045 handlers.
1046
Walter Dörwald78a78b02005-09-01 12:04:29 +00001047- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001048 from the input stream, so that the output is a byte string in the correct
1049 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001050
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001051- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1052 considering it exactly like a '*'.
1053
Walter Dörwald007f8df2005-10-09 19:42:27 +00001054- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1055 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001056
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001057- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1058
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001059- Patch #1413711: Certain patterns of differences were making difflib
1060 touch the recursion limit.
1061
Walter Dörwald58917a62006-03-31 15:26:22 +00001062- Bug #947906: An object oriented interface has been added to the calendar
1063 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001064 called as a script (e.g. via ``python -mcalendar``). Localized month and
1065 weekday names can be ouput (even if an exotic encoding is used) using
1066 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001067

1079
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001080- Patch #881820: look for openpty and forkpty also in libbsd.
1081
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001082- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1083 The zlib module is now builtin on Windows.
1084
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001085- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1086
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001087- Bug #1189330: configure did not correctly determine the necessary
1088 value of LINKCC if python was built with GCC 4.0.
1089
Trent Mick8321b422005-07-26 02:29:21 +00001090- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1091 vulnerability in zlib 1.2.1 and 1.2.2.
1092
Brett Cannon08cd5982005-04-24 22:26:38 +00001093- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1094 flags that change binary compatibility. Changes were also made to
1095 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001096 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001097
Bob Ippolitoed233462005-03-29 13:47:59 +00001098- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1099 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1100 no longer exists). This configure patch makes things right.
1101
Martin v. Löwise2713be2005-03-08 15:03:08 +00001102- Bug #1158607: Build with --disable-unicode again.
1103
Brett Cannon46d96232005-02-16 00:07:19 +00001104- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1105 defined. Discovered as a result of not being able to build on OS X.
1106
Brett Cannon516592f2004-12-07 00:42:59 +00001107- setup.py now uses the directories specified in LDFLAGS using the -L option
1108 and in CPPFLAGS using the -I option for adding library and include
1109 directories, respectively, for compiling extension modules against. This has
1110 led to the core being compiled using the values in CPPFLAGS. It also removes
1111 the need for the special-casing of both DarwinPorts and Fink for darwin since
1112 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1113 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1114 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00001116- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1117 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1118 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1119 Closes bug #1096244. Thanks Gregory Bond.

1123
Tim Petersc9d78aa2006-03-26 23:27:58 +00001124- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1125 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1126 is obtained via the ``PyObject_`` family, it must be released via the
1127 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1128 always been officially true, but when Python's small-object allocator was
1129 introduced, an attempt was made to cater to a few extension modules
1130 discovered at the time that obtained memory via ``PyObject_New`` but
1131 released it via ``PyMem_DEL``. It's years later, and if such code still
1132 exists it will fail now (probably with segfaults, but calling wrong
1133 low-level memory management functions can yield many symptoms).
1134
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001135- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001139- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1140 mapping argument now. This string is used as a mapping table. Byte values
1141 greater than the length of the string and 0xFFFE are treated as undefined
1142 mappings.
