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

11
12Core and builtins
13-----------------
14
Neal Norwitz61546162006-04-14 05:20:28 +000015- Bug #1454485, array.array('u') could crash the interpreter. This was
16 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
17 to unicode when it didn't make sense. 'u#' now requires a unicode string.
18
19- Py_UNICODE is unsigned. It was always documented as unsigned, but
20 due to a bug had a signed value in previous versions.
21
Tim Peters3a5e8b12006-04-11 01:44:07 +000022- Patch #837242: ``id()`` of any Python object always gives a positive
23 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
24 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000025 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000026 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000027
Tim Peters3a5e8b12006-04-11 01:44:07 +000028 def __hash__(self):
29 return id(self) # WRONG
30
31 because a hash result must be a (short) Python int but it was always
32 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000033 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000034 was always usable as a hash value before this patch. That's no longer
35 necessarily so.
36
37- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000038 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000039 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000040 #1454844)
41
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000042- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
43 involving generators that have paused outside of any ``try`` or ``with``
44 blocks. (In 2.5a1, a paused generator that was part of a reference
45 cycle could not be garbage collected, regardless of whether it was
46 paused in a ``try`` or ``with`` block.)

49-----------------
50
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000051- Bug #1467952: os.listdir() now correctly raises an error if readdir()
52 fails with an error condition.
53
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000054- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
55
56- Bug #1117761: bsddb.*open() no longer raises an exception when using
57 the cachesize parameter.
58
59- Bug #1149413: bsddb.*open() no longer raises an exception when using
60 a temporary db (file=None) with the 'n' flag to truncate on open.
61
62- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
63 as older versions cause excessive test failures.

66-------
67
Anthony Baxtere29002c2006-04-12 12:07:31 +000068- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
69 Windows. Bug #1469163.
70
Phillip J. Eby47032112006-04-11 01:07:43 +000071- The warnings, linecache, inspect, traceback, site, and doctest modules
72 were updated to work correctly with modules imported from zipfiles or
73 via other PEP 302 __loader__ objects.
74
Martin v. Löwis17de8ff2006-04-10 15:55:37 +000075- Patch #1467770: Reduce usage of subprocess._active to processes which
76 the application hasn't waited on.
77
Martin v. Löwisb04dee92006-04-10 08:34:21 +000078- Patch #1462222: Fix Tix.Grid.
79
Neal Norwitza31bf182006-04-09 03:35:43 +000080- Fix exception when doing glob.glob('anything*/')

84
Martin v. Löwisc90b17e2006-04-15 08:13:05 +000085- Patch #1161914: Add a python-config script.
Martin v. Löwis0f48d982006-04-14 14:34:26 +000086- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
87 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +000088 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +000089 CXX from --with-cxx-main, see description in README.
90
Martin v. Löwis10acfd02006-04-10 12:39:36 +000091- Patch #1429775: Link extension modules with the shared libpython.

Phillip J. Eby51dd7d92006-04-11 01:21:31 +000099- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
100 it separately and by hand. It also wasn't cleaning up its changes to
101 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000114Core and builtins
115-----------------
116
Martin v. Löwisea62d252006-04-03 10:56:49 +0000117- Bug #1421664: sys.stderr.encoding is now set to the same value as
118 sys.stdout.encoding.
119
Neal Norwitz92e212f2006-04-03 04:48:37 +0000120- __import__ accepts keyword arguments.
121
Georg Brandlccadf842006-03-31 18:54:53 +0000122- Patch #1460496: round() now accepts keyword arguments.
123
Anthony Baxter262c00a2006-03-30 10:53:17 +0000124- Fixed bug #1459029 - unicode reprs were double-escaped.
125
Hye-Shik Changd478f342006-03-23 12:32:36 +0000126- Patch #1396919: The system scope threads are reenabled on FreeBSD
127 5.4 and later versions.
128
Neal Norwitze98ccf62006-03-23 05:39:47 +0000129- Bug #1115379: Compiling a Unicode string with an encoding declaration
130 now gives a SyntaxError.
131
Georg Brandlabd1ff82006-03-18 07:59:59 +0000132- Previously, Python code had no easy way to access the contents of a
133 cell object. Now, a ``cell_contents`` attribute has been added
134 (closes patch #1170323).
135
Tim Peterscf79aac2006-03-16 01:14:46 +0000136- Patch #1123430: Python's small-object allocator now returns an arena to
137 the system ``free()`` when all memory within an arena becomes unused
138 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
139 freed. Some applications will see a drop in virtual memory size now,
140 especially long-running applications that, from time to time, temporarily
141 use a large number of small objects. Note that when Python returns an
142 arena to the platform C's ``free()``, there's no guarantee that the
143 platform C will in turn return that memory to the operating system. The
144 effect of the patch is to stop making that impossible, and in tests it
145 appears to be effective at least on Microsoft C and gcc-based systems.
146 Thanks to Evan Jones for hard work and patience.
147
Georg Brandl533ff6f2006-03-08 18:09:27 +0000148- Patch #1434038: property() now uses the getter's docstring if there is
149 no "doc" argument given. This makes it possible to legitimately use
150 property() as a decorator to produce a read-only property.
151
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000152- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
153 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
154 of requiring an int or long in slicing and a few other contexts, enabling
155 other objects (e.g. Numeric Python's integers) to be used as slice indices.
156
Neal Norwitz995acdf2006-03-07 05:01:00 +0000157- Fixed various bugs reported by Coverity's Prevent tool.
158
Brett Cannonbf364092006-03-01 04:25:17 +0000159- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
160 new exception base class, BaseException, which has a new message attribute.
161 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
162 Raising a string exception now raises a DeprecationWarning.
163
Thomas Woutersfb609f42006-02-28 16:37:25 +0000164- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
165 explicitly relative, using 'from .module import name' to mean 'from the same
166 package as this module is in. Imports without dots still default to the
167 old relative-then-absolute, unless 'from __future__ import
168 absolute_import' is used.
169
Brett Cannona7446e32006-02-27 23:39:10 +0000170- Properly check if 'warnings' raises an exception (usually when a filter set
171 to "error" is triggered) when raising a warning for raising string
172 exceptions.
173
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000174- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000175 The name was removed from Include/code.h.
176
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000177- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000178
Guido van Rossum1968ad32006-02-25 22:38:04 +0000179- Patch 1433928:
180 - The copy module now "copies" function objects (as atomic objects).
181 - dict.__getitem__ now looks for a __missing__ hook before raising
182 KeyError.
183
Tim Peters84ef21c2006-02-28 20:39:06 +0000184- PEP 343: with statement implemented. Needs ``from __future__ import
185 with_statement``. Use of 'with' as a variable will generate a warning.
186 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000187 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000188 The following objects have __context__ methods:
189 - The built-in file type.
190 - The thread.LockType type.
191 - The following types defined by the threading module:
192 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
193 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000194
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000195- Fix the encodings package codec search function to only search
196 inside its own package. Fixes problem reported in patch #1433198.
197
198 Note: Codec packages should implement and register their own
199 codec search function. PEP 100 has the details.
200
Martin v. Löwis18e16552006-02-15 17:27:45 +0000201- PEP 353: Using ssize_t as the index type.
202
Neal Norwitzfc76d632006-01-10 06:03:13 +0000203- Patch #1400181, fix unicode string formatting to not use the locale.
204 This is how string objects work. u'%f' could use , instead of .
205 for the decimal point. Now both strings and unicode always use periods.
206
Neal Norwitz671b9e32006-01-09 07:07:12 +0000207- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
208 configure would break checking curses.h.
209
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000210- Bug #959576: The pwd module is now builtin. This allows Python to be
211 built on UNIX platforms without $HOME set.
212
Neal Norwitzc10978f2005-12-19 06:07:16 +0000213- Bug #1072182, fix some potential problems if characters are signed.
214
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000215- Bug #889500, fix line number on SyntaxWarning for global declarations.
216
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000217- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
218
Neal Norwitze7214a12005-12-18 05:03:17 +0000219- Support for converting hex strings to floats no longer works.
220 This was not portable. float('0x3') now raises a ValueError.
221
Barry Warsaw2a38a862005-12-18 01:27:35 +0000222- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000223 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000224 is now displayed in interactive prompt banner.
225
Georg Brandlfa166682005-12-17 21:45:17 +0000226- Implementation of PEP 341 - Unification of try/except and try/finally.
227 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000228 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000229
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000230- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
231 now encodes backslash correctly.
232
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000233- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
234
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000235- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000236 and long longs.
237
Neal Norwitz67715f02005-11-09 06:59:35 +0000238- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000239 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000240 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000241
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000242- Replaced most Unicode charmap codecs with new ones using the
243 new Unicode translate string feature in the builtin charmap
244 codec; the codecs were created from the mapping tables available
245 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
246 encodings now include a mapping for the Apple logo)
247
Tim Peterse3547fd2005-12-16 23:13:57 +0000248- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000249
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000250- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000251
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000252- A new AST parser implementation was completed. The abstract
253 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000254 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000255
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000256- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000257 The following code now raises a SyntaxError: foo(a = i for i in range(10))
258
Neal Norwitz708e51a2005-10-03 04:48:15 +0000259- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
260
Neal Norwitz11bd1192005-10-03 00:54:56 +0000261- SF Bug #887946: fix segfault when redirecting stdin from a directory.
262 Provide a warning when a directory is passed on the command line.
263
Neal Norwitz40d37812005-10-02 01:48:49 +0000264- Fix segfault with invalid coding.
265
266- SF bug #772896: unknown encoding results in MemoryError.
267
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000268- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000269 supported a __len__() method which evaluated to False when the iterator
270 was empty.
271
Guido van Rossum630db602005-09-20 18:49:54 +0000272- On 64-bit platforms, when __len__() returns a value that cannot be
273 represented as a C int, raise OverflowError.
274
Skip Montanarof8948ca2005-09-19 03:54:46 +0000275- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000276 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000277
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000278- SF bug #893549: parsing keyword arguments was broken with a few format
279 codes.
280
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000281- Changes donated by Elemental Security to make it work on AIX 5.3
282 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
283 bug #105470: test_pwd fails on 64bit system (Opteron).
284
Guido van Rossum539c6622005-09-14 17:49:54 +0000285- Changes donated by Elemental Security to make it work on HP-UX 11 on
286 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
287
Georg Brandl4550b8d2005-08-26 06:43:52 +0000288- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000289 (fixes bug #1119418).
290
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000291- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
292
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000293- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
294 exceptions that cause a function to exit.
295
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000296- The implementation of set() and frozenset() was revised to use its
297 own internal data structure. Memory consumption is reduced by 1/3
298 and there are modest speed-ups as well. The API is unchanged.
299
Tim Petersde7990b2005-07-17 23:45:23 +0000300- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
301
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000302- SF bug #1229429: PyObject_CallMethod failed to decrement some
303 reference counts in some error exit cases.
304
Tim Petersecc6e6a2005-07-10 22:30:55 +0000305- SF bug #1185883: Python's small-object memory allocator took over
306 a block managed by the platform C library whenever a realloc specified
307 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000308 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000309 portable way to copy data from the C-managed block into Python's
310 small-object space without risking a memory fault. Python's small-object
311 realloc now leaves such blocks under the control of the platform C
312 realloc.
313
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000314- SF bug #1232517: An overflow error was not detected properly when
315 attempting to convert a large float to an int in os.utime().
316
Raymond Hettinger3296e692005-06-29 23:29:56 +0000317- SF bug #1224347: hex longs now print with lowercase letters just
318 like their int counterparts.
319
Michael W. Hudson188d4362005-06-20 16:52:57 +0000320- SF bug #1163563: the original fix for bug #1010677 ("thread Module
321 Breaks PyGILState_Ensure()") broke badly in the case of multiple
322 interpreter states; back out that fix and do a better job (see
323 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
324 for a longer write-up of the problem).
325
Michael W. Hudsondf888462005-06-03 14:41:55 +0000326- SF patch #1180995: marshal now uses a binary format by default when
327 serializing floats.
328
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000329- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
330 the routines that promise to produce IEEE 754 binary representations
331 of floats now simply copy bytes around.
332
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000333- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
334 278.
335
Brett Cannonc3647ac2005-04-26 03:45:26 +0000336- patch #1109424: int, long, float, complex, and unicode now check for the
337 proper magic slot for type conversions when subclassed. Previously the
338 magic slot was ignored during conversion. Semantics now match the way
339 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000340 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000341 PyNumber_*().
342 Thanks Walter Dörwald.
343
Barry Warsawc8d907c2005-04-19 23:43:40 +0000344- Descriptors defined in C with a PyGetSetDef structure, where the setter is
345 NULL, now raise an AttributeError when attempting to set or delete the
346 attribute. Previously a TypeError was raised, but this was inconsistent
347 with the equivalent pure-Python implementation.
348
Michael W. Hudson774479c2005-04-18 08:46:17 +0000349- It is now safe to call PyGILState_Release() before
350 PyEval_InitThreads() (note that if there is reason to believe there
351 are multiple threads around you still must call PyEval_InitThreads()
352 before using the Python API; this fix is for extension modules that
353 have no way of knowing if Python is multi-threaded yet).
354
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000355- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
356 disabled caused a crash.
357
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000358- Bug #1165306: instancemethod_new allowed the creation of a method
359 with im_class == im_self == NULL, which caused a crash when called.
360
Tim Petersecc6e6a2005-07-10 22:30:55 +0000361- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000362 fixes the crash seen in bug #1165761
363
Raymond Hettinger96229b12005-03-11 06:49:40 +0000364- Added two new builtins, any() and all().
365
Brett Cannon409d8f22005-03-05 06:47:57 +0000366- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000367 (e.g., ``class C(): pass`` is no longer a syntax error).
368 Patch #1176012 added support to the 'parser' module and 'compiler' package
369 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000370
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000371- Patch #1115086: Support PY_LONGLONG in structmember.
372
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000373- Bug #1155938: new style classes did not check that __init__() was
374 returning None.
375
Tim Petersecc6e6a2005-07-10 22:30:55 +0000376- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000377 ('\') with a specific error message.
378
Martin v. Löwisff232d72005-03-03 09:24:38 +0000379- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
380
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000381- Bug #1124295: the __name__ attribute of file objects was
382 inadvertently made inaccessible in restricted mode.
383
Tim Petersecc6e6a2005-07-10 22:30:55 +0000384- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000385 an ferror() call.
386
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000387- min() and max() now support key= arguments with the same meaning as in
388 list.sort().
389
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000390- The peephole optimizer now performs simple constant folding in expressions:
391 (2+3) --> (5).
392
Raymond Hettingera422c342005-01-11 03:03:27 +0000393- set and frozenset objects can now be marshalled. SF #1098985.
394
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000395- Bug #1077106: Poor argument checking could cause memory corruption
396 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000397
Jeremy Hyltonab630502005-02-04 18:44:06 +0000398- The parser did not complain about future statements in illegal
399 positions. It once again reports a syntax error if a future
400 statement occurs after anything other than a doc string.
401
Neil Schemenauercf52c072005-08-12 17:34:58 +0000402- Change the %s format specifier for str objects so that it returns a
403 unicode instance if the argument is not an instance of basestring and
404 calling __str__ on the argument returns a unicode instance.
405
Tim Petersf4e69282006-02-27 17:15:31 +0000406- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
407 current thread state when the auto-GIL-state machinery knows about
408 it (since the thread state is being deleted, continuing to remember it
409 can't help, but can hurt if another thread happens to get created with
410 the same thread id).
411
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000412Extension Modules

429
430- The following modules were removed: regsub, reconvert, regex, regex_syntax.
431
432- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000433 is deprecated. The undocumented re.engine variable no longer exists.
434

436 SS2 (single-shift 2) escape sequences correctly.
437
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000438- The unicodedata module was updated to the 4.1 version of the Unicode
439 database. The 3.2 version is still available as unicodedata.db_3_2_0
440 for applications that require this specific version (such as IDNA).
441
Neal Norwitzb62c4332006-03-04 18:35:47 +0000442- The timing module is no longer built by default. It was deprecated
443 in PEP 4 in Python 2.0 or earlier.
444
Guido van Rossum1968ad32006-02-25 22:38:04 +0000445- Patch 1433928: Added a new type, defaultdict, to the collections module.
446 This uses the new __missing__ hook behavior added to dict (see above).
447
Georg Brandldbd83392006-02-20 09:42:33 +0000448- Bug #854823: socketmodule now builds on Sun platforms even when
449 INET_ADDRSTRLEN is not defined.
450
Georg Brandlf4f44152006-02-18 22:29:33 +0000451- Patch #1393157: os.startfile() now has an optional argument to specify
452 a "command verb" to invoke on the file.
453
Neal Norwitz082b2df2006-02-07 07:04:46 +0000454- Bug #876637, prevent stack corruption when socket descriptor

462 than the system default domain.
463
Martin v. Löwis14694662006-02-03 12:54:16 +0000464- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
465 are reported, the limit on path name lengths is removed, and stat reports
466 WindowsError now (instead of OSError).
467

585
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000586- the cPickle module no longer accepts the deprecated None option in the
587 args tuple returned by __reduce__().
588
Raymond Hettingerb2594052004-12-05 09:25:51 +0000589- itertools.islice() now accepts None for the start and step arguments.
590 This allows islice() to work more readily with slices:

600-------
601

610 in attribute values.
611
Anthony Baxterc51ee692006-04-01 00:57:31 +0000612- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000613 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000614 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000615 module will not be built.
616
Tim Petersc17976e2006-04-01 00:26:53 +0000617- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
618 aren't officially supported here, and trying to use them will probably
619 raise an exception some day. But dicts have been allowed, and "mostly
620 worked", so support for them won't go away without warning.
621
Georg Brandl338ef7d2006-03-31 18:42:16 +0000622- Bug #1445068: getpass.getpass() can now be given an explicit stream
623 argument to specify where to write the prompt.
624
Georg Brandl22ec80b2006-03-31 18:25:44 +0000625- Patch #1462313, bug #1443328: the pickle modules now can handle classes

631 key to be used for signing the uploaded code.
632
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000633- Queue.Queue objects now support .task_done() and .join() methods
634 to make it easier to monitor when daemon threads have completed
635 processing all enqueued tasks. Patch #1455676.
636
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000637- popen2.Popen objects now preserve the command in a .cmd attribute.
638

640
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000641- email 4.0 package now integrated. This is largely the same as the email 3.0
642 package that was included in Python 2.3, except that PEP 8 module names are
643 now used (e.g. mail.message instead of email.Message). The MIME classes
644 have been moved to a subpackage (e.g. email.mime.text instead of
645 email.MIMEText). The old names are still supported for now. Several
646 deprecated Message methods have been removed and lots of bugs have been
647 fixed. More details can be found in the email package documentation.
648
Walter Dörwald40108c92006-03-27 08:15:44 +0000649- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
650 (a subclass of tuple) that provides incremental decoders and encoders
651 (a way to use stateful codecs without the stream API). Python functions
652 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
653 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
654 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000655
Walter Dörwald067db482006-03-15 22:17:27 +0000656- Patch #1359365: Calling next() on a closed StringIO.String object raises
657 a ValueError instead of a StopIteration now (like file and cString.String do).
658 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
659 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000660
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000661- A regrtest option -w was added to re-run failed tests in verbose mode.

734 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
735 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
736 Ronald L. Rivest offered this advice for Python:
737
738 "The consensus of researchers in this area (at least as
739 expressed at the NIST Hash Function Workshop 10/31/05),
740 is that SHA-256 is a good choice for the time being, but
741 that research should continue, and other alternatives may
742 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000743
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000744- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +0000841 the generate_tokens() function now accepts a callable argument that
842 terminates by raising StopIteration.
843
Georg Brandl9166e1a2005-06-04 09:20:03 +0000844- Bug #1196315: fix weakref.WeakValueDictionary constructor.
845
Georg Brandl268e61c2005-06-03 14:28:50 +0000846- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
847 component of the path.
848
Skip Montanaro174dd222005-05-14 20:54:16 +0000849- Patch #1120353: The xmlrpclib module provides better, more transparent,
850 support for datetime.{datetime,date,time} objects. With use_datetime set
851 to True, applications shouldn't have to fiddle with the DateTime wrapper
852 class at all.
853
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000854- distutils.commands.upload was added to support uploading distribution
855 files to PyPI.
856
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000857- distutils.commands.register now encodes the data as UTF-8 before posting
858 them to PyPI.
859
Raymond Hettinger267b8682005-03-27 10:47:39 +0000860- decimal operator and comparison methods now return NotImplemented
861 instead of raising a TypeError when interacting with other types. This
862 allows other classes to implement __radd__ style methods and have them
863 work as expected.
864
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000865- Bug #1163325: Decimal infinities failed to hash. Attempting to
866 hash a NaN raised an InvalidOperation instead of a TypeError.
867
Tim Petersecc6e6a2005-07-10 22:30:55 +0000868- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000869 stream compression; add, for symmetry reasons, r:* as a synonym of r.
870
Martin v. Löwis00a73e72005-03-04 19:40:34 +0000871- Patch #1043890: Add extractall method to tarfile.
872
Martin v. Löwisc72dd382005-03-04 13:50:17 +0000873- Patch #1075887: Don't require MSVC in distutils if there is nothing
874 to build.
875
Martin v. Löwis637431b2005-03-03 23:12:42 +0000876- Patch #1103407: Properly deal with tarfile iterators when untarring
877 symbolic links on Windows.
878
Tim Petersecc6e6a2005-07-10 22:30:55 +0000879- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +0000880 profile.py if available.
881
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +0000882- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
883
Martin v. Löwisc5574e82005-03-03 10:57:37 +0000884- Patch #1117454: Remove code to special-case cookies without values
885 in LWPCookieJar.
886
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +0000887- Patch #1117339: Add cookielib special name tests.
888
Martin v. Löwise869eb12005-03-03 09:46:07 +0000889- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
890
Martin v. Löwisf2a8d632005-03-03 08:35:22 +0000891- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
892
Martin v. Löwisdf241532005-03-03 08:17:42 +0000893- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
894
Martin v. Löwis8ed338a2005-03-03 08:12:27 +0000895- Patch #1104111: Alter setup.py --help and --help-commands.
896
Martin v. Löwis4afe1542005-03-01 08:09:28 +0000897- Patch #1121234: Properly cleanup _exit and tkerror commands.
898
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +0000899- Patch #1049151: xdrlib now unpacks booleans as True or False.
900
Raymond Hettingerbab41432005-02-05 01:31:19 +0000901- Fixed bug in a NameError bug in cookielib. Patch #1116583.
902
Guido van Rossumd0641422005-02-03 15:01:24 +0000903- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
904 disables recursive traversal through instance attributes, which can
905 be exploited in various ways.
906
Tim Peterse3547fd2005-12-16 23:13:57 +0000907- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000908 flags on the HTTP listening socket.
909
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000910- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
911 Fixed by reading the HTTP body in chunks instead of one big socket.read().
912
Tim Peterse3547fd2005-12-16 23:13:57 +0000913- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000914 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
915
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000916- Bug #1110478: Revert os.environ.update to do putenv again.
917
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000918- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
919
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000920- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
921
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000922- Enhancements to the csv module:
923
924 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000925 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000926 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000927 + Dialect parameter parsing has been re-implemented to improve error
928 reporting.
929 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
930 dictates.
931 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000932 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000933 types, rather than any object than can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000934 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
935 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000936 + reader now allows \r characters to be quoted (previously it only allowed
937 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000938 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000939 + Dialect classes passed to the module are no longer instantiated by
940 the module before being parsed (the former validation scheme required
941 this, but the mechanism was unreliable).
942 + The dialect registry now contains instances of the internal
943 C-coded dialect type, rather than references to python objects.
944 + the internal c-coded dialect type is now immutable.
945 + register_dialect now accepts the same keyword dialect specifications
946 as the reader and writer, allowing the user to register dialects
947 without first creating a dialect class.
948 + a configurable limit to the size of parsed fields has been added -
949 previously, an unmatched quote character could result in the entire
950 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +0000951 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000952 the parser field size limit (returning the former limit). The initial
953 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +0000954 + A line_num attribute has been added to the reader object, which tracks
955 the number of lines read from the source iterator. This is not
956 the same as the number of records returned, as records can span
957 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000958 + reader and writer objects were not being registered with the cyclic-GC.
959 This has been fixed.
960
Brett Cannone6539c42005-01-08 02:43:53 +0000961- _DummyThread objects in the threading module now delete self.__block that is
962 inherited from _Thread since it uses up a lock allocated by 'thread'. The
963 lock primitives tend to be limited in number and thus should not be wasted on
964 a _DummyThread object. Fixes bug #1089632.
965
Raymond Hettinger97db05d2005-01-07 08:15:41 +0000966- The imghdr module now detects Exif files.
967
Raymond Hettinger6065d322004-12-20 23:51:53 +0000968- StringIO.truncate() now correctly adjusts the size attribute.
969 (Bug #951915).
970
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000971- locale.py now uses an updated locale alias table (built using
972 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
973 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000974 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +0000975
Raymond Hettinger3557f422004-12-07 12:02:02 +0000976- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
977
Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000978- the pickle module no longer accepts the deprecated None option in the
979 args tuple returned by __reduce__().
980
Brett Cannon84667c02004-12-07 03:25:18 +0000981- optparse now optionally imports gettext. This allows its use in setup.py.
982
Raymond Hettinger3489cad2004-12-05 05:20:42 +0000983- the pickle module no longer uses the deprecated bin parameter.
984
Raymond Hettinger1bc82f82004-12-05 03:58:17 +0000985- the shelve module no longer uses the deprecated binary parameter.
986
Raymond Hettinger6c92d762004-12-05 03:28:00 +0000987- the pstats module no longer uses the deprecated ignore() method.
988
Raymond Hettingerf3fa9462004-12-05 01:58:09 +0000989- the filecmp module no longer uses the deprecated use_statcache argument.
990
Raymond Hettinger664347b2004-12-04 21:21:53 +0000991- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
992 extended or overridden by subclasses. Formerly, the subclassed method would
993 be ignored by the rest of the module. (Bug #1078905).
994
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000995- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000996 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000997
Walter Dörwald36733692004-12-22 12:50:50 +0000998- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
999 once when a size argument is given. This prevents a buffer overflow in the
1000 tokenizer with very long source lines.
1001
Barry Warsaw538561e2006-01-01 21:48:54 +00001002- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1003 immediately after creating the object, without any intervening
1004 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001005
Skip Montanaro05885812005-01-16 20:48:27 +00001006- The reconvert.quote function can now emit triple-quoted strings. The
1007 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001008
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001009- ``UserString.MutableString`` now supports negative indices in
1010 ``__setitem__`` and ``__delitem__``
1011
Greg Ward40407942005-03-05 02:53:17 +00001012- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1013 correctly.
1014
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001015- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1016 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1017 character even if the user has passed a size parameter to get a proper
1018 line ending. Remove the special handling of a "\r\n" that has been split
1019 between two lines.
1020
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001021- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1022 about illegal code points. The codec now supports PEP 293 style error
1023 handlers.
1024
Walter Dörwald78a78b02005-09-01 12:04:29 +00001025- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001026 from the input stream, so that the output is a byte string in the correct
1027 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001028
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001029- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1030 considering it exactly like a '*'.
1031
Walter Dörwald007f8df2005-10-09 19:42:27 +00001032- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1033 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001034
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001035- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1036
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001037- Patch #1413711: Certain patterns of differences were making difflib
1038 touch the recursion limit.
1039
Walter Dörwald58917a62006-03-31 15:26:22 +00001040- Bug #947906: An object oriented interface has been added to the calendar
1041 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001042 called as a script (e.g. via ``python -mcalendar``). Localized month and
1043 weekday names can be ouput (even if an exotic encoding is used) using
1044 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001045

1047-----
1048
Neal Norwitz602d3392006-03-31 08:21:40 +00001049- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1050 by using -mieee gcc option.
1051
Martin v. Löwis86d66262006-02-17 08:40:11 +00001052- Patch #1432345: Make python compile on DragonFly.
1053
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001054- Build support for Win64-AMD64 was added.
1055
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001056- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1057
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001058- Patch #881820: look for openpty and forkpty also in libbsd.
1059
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001060- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1061 The zlib module is now builtin on Windows.
1062
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001063- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1064
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001065- Bug #1189330: configure did not correctly determine the necessary
1066 value of LINKCC if python was built with GCC 4.0.
1067
Trent Mick8321b422005-07-26 02:29:21 +00001068- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1069 vulnerability in zlib 1.2.1 and 1.2.2.
1070
Brett Cannon08cd5982005-04-24 22:26:38 +00001071- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1072 flags that change binary compatibility. Changes were also made to
1073 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001074 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001075
Bob Ippolitoed233462005-03-29 13:47:59 +00001076- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1077 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1078 no longer exists). This configure patch makes things right.
1079
Martin v. Löwise2713be2005-03-08 15:03:08 +00001080- Bug #1158607: Build with --disable-unicode again.
1081
Brett Cannon46d96232005-02-16 00:07:19 +00001082- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1083 defined. Discovered as a result of not being able to build on OS X.
1084
Brett Cannon516592f2004-12-07 00:42:59 +00001085- setup.py now uses the directories specified in LDFLAGS using the -L option
1086 and in CPPFLAGS using the -I option for adding library and include
1087 directories, respectively, for compiling extension modules against. This has
1088 led to the core being compiled using the values in CPPFLAGS. It also removes
1089 the need for the special-casing of both DarwinPorts and Fink for darwin since
1090 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1091 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1092 Fink, ``-I/opt/local/include`` for DarwinPorts).
1093
Brett Cannon43802422005-02-10 20:48:03 +00001094- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1095 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1096 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1097 Closes bug #1096244. Thanks Gregory Bond.

1100-----
1101
Tim Petersc9d78aa2006-03-26 23:27:58 +00001102- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1103 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1104 is obtained via the ``PyObject_`` family, it must be released via the
1105 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1106 always been officially true, but when Python's small-object allocator was
1107 introduced, an attempt was made to cater to a few extension modules
1108 discovered at the time that obtained memory via ``PyObject_New`` but
1109 released it via ``PyMem_DEL``. It's years later, and if such code still
