Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================

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 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

76
Martin v. Löwis4b501e62006-04-15 08:41:11 +000077- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
78
Anthony Baxtere29002c2006-04-12 12:07:31 +000079- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
80 Windows. Bug #1469163.
81
Phillip J. Eby47032112006-04-11 01:07:43 +000082- The warnings, linecache, inspect, traceback, site, and doctest modules
83 were updated to work correctly with modules imported from zipfiles or
84 via other PEP 302 __loader__ objects.
85
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000086- Patch #1467770: Reduce usage of subprocess._active to processes which
87 the application hasn't waited on.
88
Martin v. Löwisb04dee92006-04-10 08:34:21 +000089- Patch #1462222: Fix Tix.Grid.

Martin v. Löwis48bbaf22006-04-15 18:06:54 +000099
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000100- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
101 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000102 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000103 CXX from --with-cxx-main, see description in README.
104
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000105- Patch #1429775: Link extension modules with the shared libpython.

112
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000113- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
114 it separately and by hand. It also wasn't cleaning up its changes to
115 the current Decimal context.

130
Martin v. Löwisea62d252006-04-03 10:56:49 +0000131- Bug #1421664: sys.stderr.encoding is now set to the same value as
132 sys.stdout.encoding.
133
Neal Norwitz92e212f2006-04-03 04:48:37 +0000134- __import__ accepts keyword arguments.
135
Georg Brandlccadf842006-03-31 18:54:53 +0000136- Patch #1460496: round() now accepts keyword arguments.
137
Anthony Baxter262c00a2006-03-30 10:53:17 +0000138- Fixed bug #1459029 - unicode reprs were double-escaped.
139
Hye-Shik Changd478f342006-03-23 12:32:36 +0000140- Patch #1396919: The system scope threads are reenabled on FreeBSD
141 5.4 and later versions.
142
Neal Norwitze98ccf62006-03-23 05:39:47 +0000143- Bug #1115379: Compiling a Unicode string with an encoding declaration
144 now gives a SyntaxError.
145
Georg Brandlabd1ff82006-03-18 07:59:59 +0000146- Previously, Python code had no easy way to access the contents of a
147 cell object. Now, a ``cell_contents`` attribute has been added
148 (closes patch #1170323).
149
Tim Peterscf79aac2006-03-16 01:14:46 +0000150- Patch #1123430: Python's small-object allocator now returns an arena to
151 the system ``free()`` when all memory within an arena becomes unused
152 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
153 freed. Some applications will see a drop in virtual memory size now,
154 especially long-running applications that, from time to time, temporarily
155 use a large number of small objects. Note that when Python returns an
156 arena to the platform C's ``free()``, there's no guarantee that the
157 platform C will in turn return that memory to the operating system. The
158 effect of the patch is to stop making that impossible, and in tests it
159 appears to be effective at least on Microsoft C and gcc-based systems.
160 Thanks to Evan Jones for hard work and patience.
161
Georg Brandl533ff6f2006-03-08 18:09:27 +0000162- Patch #1434038: property() now uses the getter's docstring if there is
163 no "doc" argument given. This makes it possible to legitimately use
164 property() as a decorator to produce a read-only property.
165
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000166- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
167 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
168 of requiring an int or long in slicing and a few other contexts, enabling
169 other objects (e.g. Numeric Python's integers) to be used as slice indices.
170
Neal Norwitz995acdf2006-03-07 05:01:00 +0000171- Fixed various bugs reported by Coverity's Prevent tool.
172
Brett Cannonbf364092006-03-01 04:25:17 +0000173- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
174 new exception base class, BaseException, which has a new message attribute.
175 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
176 Raising a string exception now raises a DeprecationWarning.
177
Thomas Woutersfb609f42006-02-28 16:37:25 +0000178- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
179 explicitly relative, using 'from .module import name' to mean 'from the same
180 package as this module is in. Imports without dots still default to the
181 old relative-then-absolute, unless 'from __future__ import
182 absolute_import' is used.
183
Brett Cannona7446e32006-02-27 23:39:10 +0000184- Properly check if 'warnings' raises an exception (usually when a filter set
185 to "error" is triggered) when raising a warning for raising string
186 exceptions.
187
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000188- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000189 The name was removed from Include/code.h.
190
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000191- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000192
Guido van Rossum1968ad32006-02-25 22:38:04 +0000193- Patch 1433928:
194 - The copy module now "copies" function objects (as atomic objects).
195 - dict.__getitem__ now looks for a __missing__ hook before raising
196 KeyError.
197
Tim Peters84ef21c2006-02-28 20:39:06 +0000198- PEP 343: with statement implemented. Needs ``from __future__ import
199 with_statement``. Use of 'with' as a variable will generate a warning.
200 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000201 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000202 The following objects have __context__ methods:
203 - The built-in file type.
204 - The thread.LockType type.
205 - The following types defined by the threading module:
206 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
207 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000208
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000209- Fix the encodings package codec search function to only search
210 inside its own package. Fixes problem reported in patch #1433198.
211
212 Note: Codec packages should implement and register their own
213 codec search function. PEP 100 has the details.
214
Martin v. Löwis18e16552006-02-15 17:27:45 +0000215- PEP 353: Using ssize_t as the index type.
216
Neal Norwitzfc76d632006-01-10 06:03:13 +0000217- Patch #1400181, fix unicode string formatting to not use the locale.
218 This is how string objects work. u'%f' could use , instead of .
219 for the decimal point. Now both strings and unicode always use periods.
220
Neal Norwitz671b9e32006-01-09 07:07:12 +0000221- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
222 configure would break checking curses.h.
223
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000224- Bug #959576: The pwd module is now builtin. This allows Python to be
225 built on UNIX platforms without $HOME set.
226
Neal Norwitzc10978f2005-12-19 06:07:16 +0000227- Bug #1072182, fix some potential problems if characters are signed.
228
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000229- Bug #889500, fix line number on SyntaxWarning for global declarations.
230
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000231- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
232
Neal Norwitze7214a12005-12-18 05:03:17 +0000233- Support for converting hex strings to floats no longer works.
234 This was not portable. float('0x3') now raises a ValueError.
235
Barry Warsaw2a38a862005-12-18 01:27:35 +0000236- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000237 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000238 is now displayed in interactive prompt banner.
239
Georg Brandlfa166682005-12-17 21:45:17 +0000240- Implementation of PEP 341 - Unification of try/except and try/finally.
241 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000242 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000243
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000244- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
245 now encodes backslash correctly.
246
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000247- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
248
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000249- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000250 and long longs.
251
Neal Norwitz67715f02005-11-09 06:59:35 +0000252- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000253 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000254 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000255
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000256- Replaced most Unicode charmap codecs with new ones using the
257 new Unicode translate string feature in the builtin charmap
258 codec; the codecs were created from the mapping tables available
259 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
260 encodings now include a mapping for the Apple logo)
261
Tim Peterse3547fd2005-12-16 23:13:57 +0000262- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000263
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000264- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000265
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000266- A new AST parser implementation was completed. The abstract
267 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000268 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000269
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000270- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000271 The following code now raises a SyntaxError: foo(a = i for i in range(10))
272
Neal Norwitz708e51a2005-10-03 04:48:15 +0000273- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
274
Neal Norwitz11bd1192005-10-03 00:54:56 +0000275- SF Bug #887946: fix segfault when redirecting stdin from a directory.
276 Provide a warning when a directory is passed on the command line.
277
Neal Norwitz40d37812005-10-02 01:48:49 +0000278- Fix segfault with invalid coding.
279
280- SF bug #772896: unknown encoding results in MemoryError.
281
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000282- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000283 supported a __len__() method which evaluated to False when the iterator
284 was empty.
285
Guido van Rossum630db602005-09-20 18:49:54 +0000286- On 64-bit platforms, when __len__() returns a value that cannot be
287 represented as a C int, raise OverflowError.
288
Skip Montanarof8948ca2005-09-19 03:54:46 +0000289- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000290 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000291
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000292- SF bug #893549: parsing keyword arguments was broken with a few format
293 codes.
294
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000295- Changes donated by Elemental Security to make it work on AIX 5.3
296 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
297 bug #105470: test_pwd fails on 64bit system (Opteron).
298
Guido van Rossum539c6622005-09-14 17:49:54 +0000299- Changes donated by Elemental Security to make it work on HP-UX 11 on
300 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
301
Georg Brandl4550b8d2005-08-26 06:43:52 +0000302- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000303 (fixes bug #1119418).
304
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000305- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
306
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000307- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
308 exceptions that cause a function to exit.
309
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000310- The implementation of set() and frozenset() was revised to use its
311 own internal data structure. Memory consumption is reduced by 1/3
312 and there are modest speed-ups as well. The API is unchanged.
313
Tim Petersde7990b2005-07-17 23:45:23 +0000314- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
315
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000316- SF bug #1229429: PyObject_CallMethod failed to decrement some
317 reference counts in some error exit cases.
318
Tim Petersecc6e6a2005-07-10 22:30:55 +0000319- SF bug #1185883: Python's small-object memory allocator took over
320 a block managed by the platform C library whenever a realloc specified
321 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000322 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000323 portable way to copy data from the C-managed block into Python's
324 small-object space without risking a memory fault. Python's small-object
325 realloc now leaves such blocks under the control of the platform C
326 realloc.
327
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000328- SF bug #1232517: An overflow error was not detected properly when
329 attempting to convert a large float to an int in os.utime().
330
Raymond Hettinger3296e692005-06-29 23:29:56 +0000331- SF bug #1224347: hex longs now print with lowercase letters just
332 like their int counterparts.
333
Michael W. Hudson188d4362005-06-20 16:52:57 +0000334- SF bug #1163563: the original fix for bug #1010677 ("thread Module
335 Breaks PyGILState_Ensure()") broke badly in the case of multiple
336 interpreter states; back out that fix and do a better job (see
337 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
338 for a longer write-up of the problem).
339
Michael W. Hudsondf888462005-06-03 14:41:55 +0000340- SF patch #1180995: marshal now uses a binary format by default when
341 serializing floats.
342
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000343- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
344 the routines that promise to produce IEEE 754 binary representations
345 of floats now simply copy bytes around.
346
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000347- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
348 278.
349
Brett Cannonc3647ac2005-04-26 03:45:26 +0000350- patch #1109424: int, long, float, complex, and unicode now check for the
351 proper magic slot for type conversions when subclassed. Previously the
352 magic slot was ignored during conversion. Semantics now match the way
353 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000354 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000355 PyNumber_*().
356 Thanks Walter Dörwald.
357
Barry Warsawc8d907c2005-04-19 23:43:40 +0000358- Descriptors defined in C with a PyGetSetDef structure, where the setter is
359 NULL, now raise an AttributeError when attempting to set or delete the
360 attribute. Previously a TypeError was raised, but this was inconsistent
361 with the equivalent pure-Python implementation.
362
Michael W. Hudson774479c2005-04-18 08:46:17 +0000363- It is now safe to call PyGILState_Release() before
364 PyEval_InitThreads() (note that if there is reason to believe there
365 are multiple threads around you still must call PyEval_InitThreads()
366 before using the Python API; this fix is for extension modules that
367 have no way of knowing if Python is multi-threaded yet).
368
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000369- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
370 disabled caused a crash.
371
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000372- Bug #1165306: instancemethod_new allowed the creation of a method
373 with im_class == im_self == NULL, which caused a crash when called.
374
Tim Petersecc6e6a2005-07-10 22:30:55 +0000375- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000376 fixes the crash seen in bug #1165761
377
Raymond Hettinger96229b12005-03-11 06:49:40 +0000378- Added two new builtins, any() and all().
379
Brett Cannon409d8f22005-03-05 06:47:57 +0000380- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000381 (e.g., ``class C(): pass`` is no longer a syntax error).
382 Patch #1176012 added support to the 'parser' module and 'compiler' package
383 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000384
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000385- Patch #1115086: Support PY_LONGLONG in structmember.
386
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000387- Bug #1155938: new style classes did not check that __init__() was
388 returning None.
389
Tim Petersecc6e6a2005-07-10 22:30:55 +0000390- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000391 ('\') with a specific error message.
392
Martin v. Löwisff232d72005-03-03 09:24:38 +0000393- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
394
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000395- Bug #1124295: the __name__ attribute of file objects was
396 inadvertently made inaccessible in restricted mode.
397
Tim Petersecc6e6a2005-07-10 22:30:55 +0000398- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000399 an ferror() call.
400
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000401- min() and max() now support key= arguments with the same meaning as in
402 list.sort().
403
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000404- The peephole optimizer now performs simple constant folding in expressions:
405 (2+3) --> (5).
406
Raymond Hettingera422c342005-01-11 03:03:27 +0000407- set and frozenset objects can now be marshalled. SF #1098985.
408
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000409- Bug #1077106: Poor argument checking could cause memory corruption
410 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000411
Jeremy Hyltonab630502005-02-04 18:44:06 +0000412- The parser did not complain about future statements in illegal
413 positions. It once again reports a syntax error if a future
414 statement occurs after anything other than a doc string.
415
Neil Schemenauercf52c072005-08-12 17:34:58 +0000416- Change the %s format specifier for str objects so that it returns a
417 unicode instance if the argument is not an instance of basestring and
418 calling __str__ on the argument returns a unicode instance.
419
Tim Petersf4e69282006-02-27 17:15:31 +0000420- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
421 current thread state when the auto-GIL-state machinery knows about
422 it (since the thread state is being deleted, continuing to remember it
423 can't help, but can hurt if another thread happens to get created with
424 the same thread id).
425
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000426Extension Modules

451
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000452- The unicodedata module was updated to the 4.1 version of the Unicode
453 database. The 3.2 version is still available as unicodedata.db_3_2_0
454 for applications that require this specific version (such as IDNA).
455
Neal Norwitzb62c4332006-03-04 18:35:47 +0000456- The timing module is no longer built by default. It was deprecated
457 in PEP 4 in Python 2.0 or earlier.
458
Guido van Rossum1968ad32006-02-25 22:38:04 +0000459- Patch 1433928: Added a new type, defaultdict, to the collections module.
460 This uses the new __missing__ hook behavior added to dict (see above).
461
Georg Brandldbd83392006-02-20 09:42:33 +0000462- Bug #854823: socketmodule now builds on Sun platforms even when
463 INET_ADDRSTRLEN is not defined.
464
Georg Brandlf4f44152006-02-18 22:29:33 +0000465- Patch #1393157: os.startfile() now has an optional argument to specify
466 a "command verb" to invoke on the file.
467
Neal Norwitz082b2df2006-02-07 07:04:46 +0000468- Bug #876637, prevent stack corruption when socket descriptor

472 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
473 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
474
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000475- Patch #1422385: The nis module now supports access to domains other
476 than the system default domain.
477
Martin v. Löwis14694662006-02-03 12:54:16 +0000478- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
479 are reported, the limit on path name lengths is removed, and stat reports
480 WindowsError now (instead of OSError).
481
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000482- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

602
Raymond Hettingerb2594052004-12-05 09:25:51 +0000603- itertools.islice() now accepts None for the start and step arguments.
604 This allows islice() to work more readily with slices:
605 islice(s.start, s.stop, s.step)

624 in attribute values.
625
Anthony Baxterc51ee692006-04-01 00:57:31 +0000626- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000627 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000628 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000629 module will not be built.
630
Tim Petersc17976e2006-04-01 00:26:53 +0000631- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
632 aren't officially supported here, and trying to use them will probably
633 raise an exception some day. But dicts have been allowed, and "mostly
634 worked", so support for them won't go away without warning.
635
Georg Brandl338ef7d2006-03-31 18:42:16 +0000636- Bug #1445068: getpass.getpass() can now be given an explicit stream
637 argument to specify where to write the prompt.
638
Georg Brandl22ec80b2006-03-31 18:25:44 +0000639- Patch #1462313, bug #1443328: the pickle modules now can handle classes

645 key to be used for signing the uploaded code.
646
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000647- Queue.Queue objects now support .task_done() and .join() methods
648 to make it easier to monitor when daemon threads have completed
649 processing all enqueued tasks. Patch #1455676.
650
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000651- popen2.Popen objects now preserve the command in a .cmd attribute.

654
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000655- email 4.0 package now integrated. This is largely the same as the email 3.0
656 package that was included in Python 2.3, except that PEP 8 module names are
657 now used (e.g. mail.message instead of email.Message). The MIME classes
658 have been moved to a subpackage (e.g. email.mime.text instead of
659 email.MIMEText). The old names are still supported for now. Several
660 deprecated Message methods have been removed and lots of bugs have been
661 fixed. More details can be found in the email package documentation.
662
Walter Dörwald40108c92006-03-27 08:15:44 +0000663- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
664 (a subclass of tuple) that provides incremental decoders and encoders
665 (a way to use stateful codecs without the stream API). Python functions
666 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
667 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
668 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000669
Walter Dörwald067db482006-03-15 22:17:27 +0000670- Patch #1359365: Calling next() on a closed StringIO.String object raises
671 a ValueError instead of a StopIteration now (like file and cString.String do).
672 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
673 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000674

751
752 "The consensus of researchers in this area (at least as
753 expressed at the NIST Hash Function Workshop 10/31/05),
754 is that SHA-256 is a good choice for the time being, but
755 that research should continue, and other alternatives may
756 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000757

Georg Brandlfbff1bc2005-06-26 21:36:25 +0000845- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
846 error messages.
847
Georg Brandl379f99d2005-06-26 21:09:38 +0000848- Bug #1108948: Cookie.py produced invalid JavaScript code.
849
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000850- The tokenize module now detects and reports indentation errors.
851 Bug #1224621.
852
Raymond Hettinger68c04532005-06-10 11:05:19 +0000853- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000854 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000855 the generate_tokens() function now accepts a callable argument that
856 terminates by raising StopIteration.
857
Georg Brandl9166e1a2005-06-04 09:20:03 +0000858- Bug #1196315: fix weakref.WeakValueDictionary constructor.
859
Georg Brandl268e61c2005-06-03 14:28:50 +0000860- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
861 component of the path.
862
Skip Montanaro174dd222005-05-14 20:54:16 +0000863- Patch #1120353: The xmlrpclib module provides better, more transparent,
864 support for datetime.{datetime,date,time} objects. With use_datetime set
865 to True, applications shouldn't have to fiddle with the DateTime wrapper
866 class at all.
867
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000868- distutils.commands.upload was added to support uploading distribution
869 files to PyPI.
870
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000871- distutils.commands.register now encodes the data as UTF-8 before posting
872 them to PyPI.
873
Raymond Hettinger267b8682005-03-27 10:47:39 +0000874- decimal operator and comparison methods now return NotImplemented
875 instead of raising a TypeError when interacting with other types. This
876 allows other classes to implement __radd__ style methods and have them
877 work as expected.
878
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000879- Bug #1163325: Decimal infinities failed to hash. Attempting to
880 hash a NaN raised an InvalidOperation instead of a TypeError.
881
Tim Petersecc6e6a2005-07-10 22:30:55 +0000882- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000883 stream compression; add, for symmetry reasons, r:* as a synonym of r.
884
Martin v. Löwis00a73e72005-03-04 19:40:34 +0000885- Patch #1043890: Add extractall method to tarfile.
886
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000887- Patch #1075887: Don't require MSVC in distutils if there is nothing
888 to build.
889
Martin v. Löwis637431b2005-03-03 23:12:42 +0000890- Patch #1103407: Properly deal with tarfile iterators when untarring
891 symbolic links on Windows.
892
Tim Petersecc6e6a2005-07-10 22:30:55 +0000893- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000894 profile.py if available.
895

897
Martin v. Löwisc5574e82005-03-03 10:57:37 +0000898- Patch #1117454: Remove code to special-case cookies without values
899 in LWPCookieJar.
900
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +0000901- Patch #1117339: Add cookielib special name tests.

Martin v. Löwisf2a8d632005-03-03 08:35:22 +0000905- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
906
Martin v. Löwisdf241532005-03-03 08:17:42 +0000907- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
908
Martin v. Löwis8ed338a2005-03-03 08:12:27 +0000909- Patch #1104111: Alter setup.py --help and --help-commands.
910
Martin v. Löwis4afe1542005-03-01 08:09:28 +0000911- Patch #1121234: Properly cleanup _exit and tkerror commands.
912
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +0000913- Patch #1049151: xdrlib now unpacks booleans as True or False.
914
Raymond Hettingerbab41432005-02-05 01:31:19 +0000915- Fixed bug in a NameError bug in cookielib. Patch #1116583.
916
Guido van Rossumd0641422005-02-03 15:01:24 +0000917- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
918 disables recursive traversal through instance attributes, which can
919 be exploited in various ways.
920
Tim Peterse3547fd2005-12-16 23:13:57 +0000921- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000922 flags on the HTTP listening socket.
923
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000924- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
925 Fixed by reading the HTTP body in chunks instead of one big socket.read().
926
Tim Peterse3547fd2005-12-16 23:13:57 +0000927- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000928 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
929

933
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000934- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
935
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000936- Enhancements to the csv module:
937
938 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000939 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000940 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000941 + Dialect parameter parsing has been re-implemented to improve error
942 reporting.
943 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
944 dictates.
945 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000946 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000947 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000948 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
949 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000950 + reader now allows \r characters to be quoted (previously it only allowed
951 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000952 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000953 + Dialect classes passed to the module are no longer instantiated by
954 the module before being parsed (the former validation scheme required
955 this, but the mechanism was unreliable).
956 + The dialect registry now contains instances of the internal
957 C-coded dialect type, rather than references to python objects.
958 + the internal c-coded dialect type is now immutable.
959 + register_dialect now accepts the same keyword dialect specifications
960 as the reader and writer, allowing the user to register dialects
961 without first creating a dialect class.
962 + a configurable limit to the size of parsed fields has been added -
963 previously, an unmatched quote character could result in the entire
964 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000965 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000966 the parser field size limit (returning the former limit). The initial
967 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000968 + A line_num attribute has been added to the reader object, which tracks
969 the number of lines read from the source iterator. This is not
970 the same as the number of records returned, as records can span
971 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000972 + reader and writer objects were not being registered with the cyclic-GC.
973 This has been fixed.
974
Brett Cannone6539c42005-01-08 02:43:53 +0000975- _DummyThread objects in the threading module now delete self.__block that is
976 inherited from _Thread since it uses up a lock allocated by 'thread'. The
977 lock primitives tend to be limited in number and thus should not be wasted on
978 a _DummyThread object. Fixes bug #1089632.
979
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000980- The imghdr module now detects Exif files.
981
Raymond Hettinger6065d322004-12-20 23:51:53 +0000982- StringIO.truncate() now correctly adjusts the size attribute.
983 (Bug #951915).
984
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000985- locale.py now uses an updated locale alias table (built using
986 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
987 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000988 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000989
Raymond Hettinger3557f422004-12-07 12:02:02 +0000990- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
991
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000992- the pickle module no longer accepts the deprecated None option in the
993 args tuple returned by __reduce__().
994
Brett Cannon84667c02004-12-07 03:25:18 +0000995- optparse now optionally imports gettext. This allows its use in setup.py.
996
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000997- the pickle module no longer uses the deprecated bin parameter.
998
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000999- the shelve module no longer uses the deprecated binary parameter.
1000
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001001- the pstats module no longer uses the deprecated ignore() method.
1002
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001003- the filecmp module no longer uses the deprecated use_statcache argument.
1004
Raymond Hettinger664347b2004-12-04 21:21:53 +00001005- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1006 extended or overridden by subclasses. Formerly, the subclassed method would
1007 be ignored by the rest of the module. (Bug #1078905).
1008
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001009- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001010 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001011
Walter Dörwald36733692004-12-22 12:50:50 +00001012- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1013 once when a size argument is given. This prevents a buffer overflow in the
1014 tokenizer with very long source lines.
1015
Barry Warsaw538561e2006-01-01 21:48:54 +00001016- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1017 immediately after creating the object, without any intervening
1018 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001019
Skip Montanaro05885812005-01-16 20:48:27 +00001020- The reconvert.quote function can now emit triple-quoted strings. The
1021 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001022
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001023- ``UserString.MutableString`` now supports negative indices in
1024 ``__setitem__`` and ``__delitem__``
1025
Greg Ward40407942005-03-05 02:53:17 +00001026- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1027 correctly.
1028
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001029- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1030 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1031 character even if the user has passed a size parameter to get a proper
1032 line ending. Remove the special handling of a "\r\n" that has been split
1033 between two lines.
1034
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001035- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1036 about illegal code points. The codec now supports PEP 293 style error
1037 handlers.
1038
Walter Dörwald78a78b02005-09-01 12:04:29 +00001039- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001040 from the input stream, so that the output is a byte string in the correct
1041 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001042
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001043- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1044 considering it exactly like a '*'.
1045
Walter Dörwald007f8df2005-10-09 19:42:27 +00001046- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1047 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001048
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001049- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1050
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001051- Patch #1413711: Certain patterns of differences were making difflib
1052 touch the recursion limit.
1053
Walter Dörwald58917a62006-03-31 15:26:22 +00001054- Bug #947906: An object oriented interface has been added to the calendar
1055 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001056 called as a script (e.g. via ``python -mcalendar``). Localized month and
1057 weekday names can be ouput (even if an exotic encoding is used) using
1058 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001059
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001060Build
1061-----
1062
Neal Norwitz602d3392006-03-31 08:21:40 +00001063- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1064 by using -mieee gcc option.
1065

1067
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001068- Build support for Win64-AMD64 was added.
1069
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001070- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1071
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001072- Patch #881820: look for openpty and forkpty also in libbsd.
1073
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001074- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1075 The zlib module is now builtin on Windows.
1076
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001077- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1078
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001079- Bug #1189330: configure did not correctly determine the necessary
1080 value of LINKCC if python was built with GCC 4.0.
1081
Trent Mick8321b422005-07-26 02:29:21 +00001082- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1083 vulnerability in zlib 1.2.1 and 1.2.2.
1084
Brett Cannon08cd5982005-04-24 22:26:38 +00001085- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1086 flags that change binary compatibility. Changes were also made to
1087 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001088 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001089
Bob Ippolitoed233462005-03-29 13:47:59 +00001090- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1091 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1092 no longer exists). This configure patch makes things right.
1093
Martin v. Löwise2713be2005-03-08 15:03:08 +00001094- Bug #1158607: Build with --disable-unicode again.
1095
Brett Cannon46d96232005-02-16 00:07:19 +00001096- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1097 defined. Discovered as a result of not being able to build on OS X.
1098
Brett Cannon516592f2004-12-07 00:42:59 +00001099- setup.py now uses the directories specified in LDFLAGS using the -L option
1100 and in CPPFLAGS using the -I option for adding library and include
1101 directories, respectively, for compiling extension modules against. This has
1102 led to the core being compiled using the values in CPPFLAGS. It also removes
1103 the need for the special-casing of both DarwinPorts and Fink for darwin since
1104 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1105 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1106 Fink, ``-I/opt/local/include`` for DarwinPorts).
1107
Brett Cannon43802422005-02-10 20:48:03 +00001108- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1109 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1110 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

Tim Petersc9d78aa2006-03-26 23:27:58 +00001116- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1117 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1118 is obtained via the ``PyObject_`` family, it must be released via the
1119 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1120 always been officially true, but when Python's small-object allocator was
1121 introduced, an attempt was made to cater to a few extension modules
1122 discovered at the time that obtained memory via ``PyObject_New`` but
1123 released it via ``PyMem_DEL``. It's years later, and if such code still
1124 exists it will fail now (probably with segfaults, but calling wrong
1125 low-level memory management functions can yield many symptoms).
1126
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001127- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001131- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1132 mapping argument now. This string is used as a mapping table. Byte values
1133 greater than the length of the string and 0xFFFE are treated as undefined
1134 mappings.
