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

11
12Core and builtins
13-----------------
14
Thomas Heller1b046642006-04-18 18:51:06 +000015- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
16 by converting these apis from macros into exported functions again:
17
18 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
19 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
20 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
21 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
22 PyRun_String Py_CompileString
23
Martin v. Löwis45294a92006-04-18 06:24:08 +000024- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
25
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000026- All uses of PyStructSequence_InitType have been changed to initialize
27 the type objects only once, even if the interpreter is initialized
28 multiple times.
29
Neal Norwitz61546162006-04-14 05:20:28 +000030- Bug #1454485, array.array('u') could crash the interpreter. This was
31 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
32 to unicode when it didn't make sense. 'u#' now requires a unicode string.
33
34- Py_UNICODE is unsigned. It was always documented as unsigned, but
35 due to a bug had a signed value in previous versions.
36
Tim Peters3a5e8b12006-04-11 01:44:07 +000037- Patch #837242: ``id()`` of any Python object always gives a positive
38 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
39 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000040 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000041 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000042
Tim Peters3a5e8b12006-04-11 01:44:07 +000043 def __hash__(self):
44 return id(self) # WRONG
45
46 because a hash result must be a (short) Python int but it was always
47 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000048 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000049 was always usable as a hash value before this patch. That's no longer
50 necessarily so.
51
52- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000053 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000054 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000055 #1454844)
56
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000057- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
58 involving generators that have paused outside of any ``try`` or ``with``
59 blocks. (In 2.5a1, a paused generator that was part of a reference
60 cycle could not be garbage collected, regardless of whether it was
61 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000062
Anthony Baxter51bcb682006-04-05 14:51:42 +000063Extension Modules
64-----------------
65
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000066- Patch #1191065: Fix preprocessor problems on systems where recvfrom
67 is a macro.
68
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000069- Bug #1467952: os.listdir() now correctly raises an error if readdir()
70 fails with an error condition.
71
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000072- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
73
74- Bug #1117761: bsddb.*open() no longer raises an exception when using
75 the cachesize parameter.
76
77- Bug #1149413: bsddb.*open() no longer raises an exception when using
78 a temporary db (file=None) with the 'n' flag to truncate on open.
79
80- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
81 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000082
Armin Rigoa9017c32006-04-19 11:50:27 +000083- Patch #1062014: AF_UNIX sockets under Linux have a special
84 abstract namespace that is now fully supported.
85
Anthony Baxter51bcb682006-04-05 14:51:42 +000086Library
87-------
88
Phillip J. Eby17a35f92006-04-18 16:45:14 +000089- New modules: setuptools, easy_install, and pkg_resources, to support
90 building, installing, and using Python eggs, respectively.
91
92- The pydoc module now supports documenting packages contained in
93 .zip or .egg files.
94
95- The pkgutil module now has several new utility functions, such
96 as ``walk_packages()`` to support working with packages that are either
97 in the filesystem or zip files.
98
99
Tim Petersc7605f22006-04-17 21:12:33 +0000100- The ``__del__`` method of class ``local`` in module ``_threading_local``
101 returned before accomplishing any of its intended cleanup.
102
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000103- Patch #790710: Add breakpoint command lists in pdb.
104
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000105- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000107- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
108
Anthony Baxtere29002c2006-04-12 12:07:31 +0000109- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
110 Windows. Bug #1469163.
111
Phillip J. Eby47032112006-04-11 01:07:43 +0000112- The warnings, linecache, inspect, traceback, site, and doctest modules
113 were updated to work correctly with modules imported from zipfiles or
114 via other PEP 302 __loader__ objects.
115
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000116- Patch #1467770: Reduce usage of subprocess._active to processes which
117 the application hasn't waited on.
118
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000119- Patch #1462222: Fix Tix.Grid.
120
Neal Norwitza31bf182006-04-09 03:35:43 +0000121- Fix exception when doing glob.glob('anything*/')
122
Anthony Baxter51bcb682006-04-05 14:51:42 +0000123Build
124-----
125
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000126- The Makefile now has a reindent target, which runs reindent.py on
127 the library.
128
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000129- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000131- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000132
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000133- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
134 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000135 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000136 CXX from --with-cxx-main, see description in README.
137
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000138- Patch #1429775: Link extension modules with the shared libpython.

145
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000146- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
147 it separately and by hand. It also wasn't cleaning up its changes to
148 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000166Core and builtins
167-----------------
168
Martin v. Löwisea62d252006-04-03 10:56:49 +0000169- Bug #1421664: sys.stderr.encoding is now set to the same value as
170 sys.stdout.encoding.
171
Neal Norwitz92e212f2006-04-03 04:48:37 +0000172- __import__ accepts keyword arguments.
173
Georg Brandlccadf842006-03-31 18:54:53 +0000174- Patch #1460496: round() now accepts keyword arguments.
175
Anthony Baxter262c00a2006-03-30 10:53:17 +0000176- Fixed bug #1459029 - unicode reprs were double-escaped.
177
Hye-Shik Changd478f342006-03-23 12:32:36 +0000178- Patch #1396919: The system scope threads are reenabled on FreeBSD
179 5.4 and later versions.
180
Neal Norwitze98ccf62006-03-23 05:39:47 +0000181- Bug #1115379: Compiling a Unicode string with an encoding declaration
182 now gives a SyntaxError.
183
Georg Brandlabd1ff82006-03-18 07:59:59 +0000184- Previously, Python code had no easy way to access the contents of a
185 cell object. Now, a ``cell_contents`` attribute has been added
186 (closes patch #1170323).
187
Tim Peterscf79aac2006-03-16 01:14:46 +0000188- Patch #1123430: Python's small-object allocator now returns an arena to
189 the system ``free()`` when all memory within an arena becomes unused
190 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
191 freed. Some applications will see a drop in virtual memory size now,
192 especially long-running applications that, from time to time, temporarily
193 use a large number of small objects. Note that when Python returns an
194 arena to the platform C's ``free()``, there's no guarantee that the
195 platform C will in turn return that memory to the operating system. The
196 effect of the patch is to stop making that impossible, and in tests it
197 appears to be effective at least on Microsoft C and gcc-based systems.
198 Thanks to Evan Jones for hard work and patience.
199
Georg Brandl533ff6f2006-03-08 18:09:27 +0000200- Patch #1434038: property() now uses the getter's docstring if there is
201 no "doc" argument given. This makes it possible to legitimately use
202 property() as a decorator to produce a read-only property.
203
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000204- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
205 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
206 of requiring an int or long in slicing and a few other contexts, enabling
207 other objects (e.g. Numeric Python's integers) to be used as slice indices.
208
Neal Norwitz995acdf2006-03-07 05:01:00 +0000209- Fixed various bugs reported by Coverity's Prevent tool.
210
Brett Cannonbf364092006-03-01 04:25:17 +0000211- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
212 new exception base class, BaseException, which has a new message attribute.
213 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
214 Raising a string exception now raises a DeprecationWarning.
215
Thomas Woutersfb609f42006-02-28 16:37:25 +0000216- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
217 explicitly relative, using 'from .module import name' to mean 'from the same
218 package as this module is in. Imports without dots still default to the
219 old relative-then-absolute, unless 'from __future__ import
220 absolute_import' is used.
221
Brett Cannona7446e32006-02-27 23:39:10 +0000222- Properly check if 'warnings' raises an exception (usually when a filter set
223 to "error" is triggered) when raising a warning for raising string
224 exceptions.
225
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000226- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000227 The name was removed from Include/code.h.
228
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000229- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000230
Guido van Rossum1968ad32006-02-25 22:38:04 +0000231- Patch 1433928:
232 - The copy module now "copies" function objects (as atomic objects).
233 - dict.__getitem__ now looks for a __missing__ hook before raising
234 KeyError.
235
Tim Peters84ef21c2006-02-28 20:39:06 +0000236- PEP 343: with statement implemented. Needs ``from __future__ import
237 with_statement``. Use of 'with' as a variable will generate a warning.
238 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000239 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000240 The following objects have __context__ methods:
241 - The built-in file type.
242 - The thread.LockType type.
243 - The following types defined by the threading module:
244 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
245 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000246
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000247- Fix the encodings package codec search function to only search
248 inside its own package. Fixes problem reported in patch #1433198.
249
250 Note: Codec packages should implement and register their own
251 codec search function. PEP 100 has the details.
252
Martin v. Löwis18e16552006-02-15 17:27:45 +0000253- PEP 353: Using ssize_t as the index type.
254
Neal Norwitzfc76d632006-01-10 06:03:13 +0000255- Patch #1400181, fix unicode string formatting to not use the locale.
256 This is how string objects work. u'%f' could use , instead of .
257 for the decimal point. Now both strings and unicode always use periods.
258
Neal Norwitz671b9e32006-01-09 07:07:12 +0000259- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
260 configure would break checking curses.h.
261
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000262- Bug #959576: The pwd module is now builtin. This allows Python to be
263 built on UNIX platforms without $HOME set.
264
Neal Norwitzc10978f2005-12-19 06:07:16 +0000265- Bug #1072182, fix some potential problems if characters are signed.
266
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000267- Bug #889500, fix line number on SyntaxWarning for global declarations.
268
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000269- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
270
Neal Norwitze7214a12005-12-18 05:03:17 +0000271- Support for converting hex strings to floats no longer works.
272 This was not portable. float('0x3') now raises a ValueError.
273
Barry Warsaw2a38a862005-12-18 01:27:35 +0000274- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000275 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000276 is now displayed in interactive prompt banner.
277
Georg Brandlfa166682005-12-17 21:45:17 +0000278- Implementation of PEP 341 - Unification of try/except and try/finally.
279 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000280 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000281
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000282- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
283 now encodes backslash correctly.
284
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000285- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
286
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000287- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000288 and long longs.
289
Neal Norwitz67715f02005-11-09 06:59:35 +0000290- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000291 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000292 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000293
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000294- Replaced most Unicode charmap codecs with new ones using the
295 new Unicode translate string feature in the builtin charmap
296 codec; the codecs were created from the mapping tables available
297 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
298 encodings now include a mapping for the Apple logo)
299
Tim Peterse3547fd2005-12-16 23:13:57 +0000300- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000301
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000302- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000303
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000304- A new AST parser implementation was completed. The abstract
305 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000306 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000307
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000308- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000309 The following code now raises a SyntaxError: foo(a = i for i in range(10))
310
Neal Norwitz708e51a2005-10-03 04:48:15 +0000311- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
312
Neal Norwitz11bd1192005-10-03 00:54:56 +0000313- SF Bug #887946: fix segfault when redirecting stdin from a directory.
314 Provide a warning when a directory is passed on the command line.
315
Neal Norwitz40d37812005-10-02 01:48:49 +0000316- Fix segfault with invalid coding.
317
318- SF bug #772896: unknown encoding results in MemoryError.
319
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000320- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000321 supported a __len__() method which evaluated to False when the iterator
322 was empty.
323
Guido van Rossum630db602005-09-20 18:49:54 +0000324- On 64-bit platforms, when __len__() returns a value that cannot be
325 represented as a C int, raise OverflowError.
326
Skip Montanarof8948ca2005-09-19 03:54:46 +0000327- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000328 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000329
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000330- SF bug #893549: parsing keyword arguments was broken with a few format
331 codes.
332
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000333- Changes donated by Elemental Security to make it work on AIX 5.3
334 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
335 bug #105470: test_pwd fails on 64bit system (Opteron).
336
Guido van Rossum539c6622005-09-14 17:49:54 +0000337- Changes donated by Elemental Security to make it work on HP-UX 11 on
338 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
339
Georg Brandl4550b8d2005-08-26 06:43:52 +0000340- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000341 (fixes bug #1119418).
342
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000343- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
344
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000345- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
346 exceptions that cause a function to exit.
347
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000348- The implementation of set() and frozenset() was revised to use its
349 own internal data structure. Memory consumption is reduced by 1/3
350 and there are modest speed-ups as well. The API is unchanged.
351
Tim Petersde7990b2005-07-17 23:45:23 +0000352- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
353
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000354- SF bug #1229429: PyObject_CallMethod failed to decrement some
355 reference counts in some error exit cases.
356
Tim Petersecc6e6a2005-07-10 22:30:55 +0000357- SF bug #1185883: Python's small-object memory allocator took over
358 a block managed by the platform C library whenever a realloc specified
359 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000360 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000361 portable way to copy data from the C-managed block into Python's
362 small-object space without risking a memory fault. Python's small-object
363 realloc now leaves such blocks under the control of the platform C
364 realloc.
365
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000366- SF bug #1232517: An overflow error was not detected properly when
367 attempting to convert a large float to an int in os.utime().
368
Raymond Hettinger3296e692005-06-29 23:29:56 +0000369- SF bug #1224347: hex longs now print with lowercase letters just
370 like their int counterparts.
371
Michael W. Hudson188d4362005-06-20 16:52:57 +0000372- SF bug #1163563: the original fix for bug #1010677 ("thread Module
373 Breaks PyGILState_Ensure()") broke badly in the case of multiple
374 interpreter states; back out that fix and do a better job (see
375 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
376 for a longer write-up of the problem).
377
Michael W. Hudsondf888462005-06-03 14:41:55 +0000378- SF patch #1180995: marshal now uses a binary format by default when
379 serializing floats.
380
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000381- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
382 the routines that promise to produce IEEE 754 binary representations
383 of floats now simply copy bytes around.
384
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000385- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
386 278.
387
Brett Cannonc3647ac2005-04-26 03:45:26 +0000388- patch #1109424: int, long, float, complex, and unicode now check for the
389 proper magic slot for type conversions when subclassed. Previously the
390 magic slot was ignored during conversion. Semantics now match the way
391 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000392 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000393 PyNumber_*().
394 Thanks Walter Dörwald.
395
Barry Warsawc8d907c2005-04-19 23:43:40 +0000396- Descriptors defined in C with a PyGetSetDef structure, where the setter is
397 NULL, now raise an AttributeError when attempting to set or delete the
398 attribute. Previously a TypeError was raised, but this was inconsistent
399 with the equivalent pure-Python implementation.
400
Michael W. Hudson774479c2005-04-18 08:46:17 +0000401- It is now safe to call PyGILState_Release() before
402 PyEval_InitThreads() (note that if there is reason to believe there
403 are multiple threads around you still must call PyEval_InitThreads()
404 before using the Python API; this fix is for extension modules that
405 have no way of knowing if Python is multi-threaded yet).
406
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000407- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
408 disabled caused a crash.
409
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000410- Bug #1165306: instancemethod_new allowed the creation of a method
411 with im_class == im_self == NULL, which caused a crash when called.
412
Tim Petersecc6e6a2005-07-10 22:30:55 +0000413- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000414 fixes the crash seen in bug #1165761
415
Raymond Hettinger96229b12005-03-11 06:49:40 +0000416- Added two new builtins, any() and all().
417
Brett Cannon409d8f22005-03-05 06:47:57 +0000418- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000419 (e.g., ``class C(): pass`` is no longer a syntax error).
420 Patch #1176012 added support to the 'parser' module and 'compiler' package
421 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000422
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000423- Patch #1115086: Support PY_LONGLONG in structmember.
424
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000425- Bug #1155938: new style classes did not check that __init__() was
426 returning None.
427
Tim Petersecc6e6a2005-07-10 22:30:55 +0000428- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000429 ('\') with a specific error message.
430
Martin v. Löwisff232d72005-03-03 09:24:38 +0000431- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
432
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000433- Bug #1124295: the __name__ attribute of file objects was
434 inadvertently made inaccessible in restricted mode.
435
Tim Petersecc6e6a2005-07-10 22:30:55 +0000436- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000437 an ferror() call.
438
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000439- min() and max() now support key= arguments with the same meaning as in
440 list.sort().
441
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000442- The peephole optimizer now performs simple constant folding in expressions:
443 (2+3) --> (5).
444
Raymond Hettingera422c342005-01-11 03:03:27 +0000445- set and frozenset objects can now be marshalled. SF #1098985.
446
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000447- Bug #1077106: Poor argument checking could cause memory corruption
448 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000449
Jeremy Hyltonab630502005-02-04 18:44:06 +0000450- The parser did not complain about future statements in illegal
451 positions. It once again reports a syntax error if a future
452 statement occurs after anything other than a doc string.
453
Neil Schemenauercf52c072005-08-12 17:34:58 +0000454- Change the %s format specifier for str objects so that it returns a
455 unicode instance if the argument is not an instance of basestring and
456 calling __str__ on the argument returns a unicode instance.
457
Tim Petersf4e69282006-02-27 17:15:31 +0000458- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
459 current thread state when the auto-GIL-state machinery knows about
460 it (since the thread state is being deleted, continuing to remember it
461 can't help, but can hurt if another thread happens to get created with
462 the same thread id).
463
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000464Extension Modules

481
482- The following modules were removed: regsub, reconvert, regex, regex_syntax.
483
484- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000485 is deprecated. The undocumented re.engine variable no longer exists.
486

488 SS2 (single-shift 2) escape sequences correctly.
489
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000490- The unicodedata module was updated to the 4.1 version of the Unicode
491 database. The 3.2 version is still available as unicodedata.db_3_2_0
492 for applications that require this specific version (such as IDNA).
493
Neal Norwitzb62c4332006-03-04 18:35:47 +0000494- The timing module is no longer built by default. It was deprecated
495 in PEP 4 in Python 2.0 or earlier.
496
Guido van Rossum1968ad32006-02-25 22:38:04 +0000497- Patch 1433928: Added a new type, defaultdict, to the collections module.
498 This uses the new __missing__ hook behavior added to dict (see above).
499
Georg Brandldbd83392006-02-20 09:42:33 +0000500- Bug #854823: socketmodule now builds on Sun platforms even when
501 INET_ADDRSTRLEN is not defined.
502
Georg Brandlf4f44152006-02-18 22:29:33 +0000503- Patch #1393157: os.startfile() now has an optional argument to specify
504 a "command verb" to invoke on the file.
505
Neal Norwitz082b2df2006-02-07 07:04:46 +0000506- Bug #876637, prevent stack corruption when socket descriptor

510 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
511 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
512
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000513- Patch #1422385: The nis module now supports access to domains other
514 than the system default domain.
515
Martin v. Löwis14694662006-02-03 12:54:16 +0000516- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
517 are reported, the limit on path name lengths is removed, and stat reports
518 WindowsError now (instead of OSError).
519
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000520- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

596 for large or negative values.
597

Raymond Hettingerb2594052004-12-05 09:25:51 +0000641- itertools.islice() now accepts None for the start and step arguments.
642 This allows islice() to work more readily with slices:

662 in attribute values.
663
Anthony Baxterc51ee692006-04-01 00:57:31 +0000664- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000665 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000666 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000667 module will not be built.
668
Tim Petersc17976e2006-04-01 00:26:53 +0000669- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
670 aren't officially supported here, and trying to use them will probably
671 raise an exception some day. But dicts have been allowed, and "mostly
672 worked", so support for them won't go away without warning.
673
Georg Brandl338ef7d2006-03-31 18:42:16 +0000674- Bug #1445068: getpass.getpass() can now be given an explicit stream
675 argument to specify where to write the prompt.
676
Georg Brandl22ec80b2006-03-31 18:25:44 +0000677- Patch #1462313, bug #1443328: the pickle modules now can handle classes

683 key to be used for signing the uploaded code.
684
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000685- Queue.Queue objects now support .task_done() and .join() methods
686 to make it easier to monitor when daemon threads have completed
687 processing all enqueued tasks. Patch #1455676.
688
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000689- popen2.Popen objects now preserve the command in a .cmd attribute.
690

692
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000693- email 4.0 package now integrated. This is largely the same as the email 3.0
694 package that was included in Python 2.3, except that PEP 8 module names are
695 now used (e.g. mail.message instead of email.Message). The MIME classes
696 have been moved to a subpackage (e.g. email.mime.text instead of
697 email.MIMEText). The old names are still supported for now. Several
698 deprecated Message methods have been removed and lots of bugs have been
699 fixed. More details can be found in the email package documentation.
700
Walter Dörwald40108c92006-03-27 08:15:44 +0000701- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
702 (a subclass of tuple) that provides incremental decoders and encoders
703 (a way to use stateful codecs without the stream API). Python functions
704 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
705 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
706 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000707
Walter Dörwald067db482006-03-15 22:17:27 +0000708- Patch #1359365: Calling next() on a closed StringIO.String object raises
709 a ValueError instead of a StopIteration now (like file and cString.String do).
710 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
711 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000712

787 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
788 Ronald L. Rivest offered this advice for Python:
789
790 "The consensus of researchers in this area (at least as
791 expressed at the NIST Hash Function Workshop 10/31/05),
792 is that SHA-256 is a good choice for the time being, but
793 that research should continue, and other alternatives may
794 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000795

861 Tkdnd.
862
Georg Brandl5dbda752005-07-17 20:27:41 +0000863- Bug #1015140: disambiguated the term "article id" in nntplib docs and
864 docstrings to either "article number" or "message id".
865
Georg Brandla4a8b822005-07-15 09:13:21 +0000866- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
867 parameter, but uses the usual "kwargs=None".
868
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000869- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +0000870 Patch #1209527 (Contributed by Connelly).
871
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000872- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
873 to W3C name (404 -> 'Not Found'). RFE #1216944.
874
Georg Brandl9e43acf2005-07-04 17:16:07 +0000875- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
876 as this can cause problems with apps closing all file descriptors.
877
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000878- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000879 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +0000880

887
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000888- The tokenize module now detects and reports indentation errors.
889 Bug #1224621.
890
Raymond Hettinger68c04532005-06-10 11:05:19 +0000891- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000892 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000893 the generate_tokens() function now accepts a callable argument that
894 terminates by raising StopIteration.
895
Georg Brandl9166e1a2005-06-04 09:20:03 +0000896- Bug #1196315: fix weakref.WeakValueDictionary constructor.
897

899 component of the path.
900
Skip Montanaro174dd222005-05-14 20:54:16 +0000901- Patch #1120353: The xmlrpclib module provides better, more transparent,
902 support for datetime.{datetime,date,time} objects. With use_datetime set
903 to True, applications shouldn't have to fiddle with the DateTime wrapper
904 class at all.
905
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000906- distutils.commands.upload was added to support uploading distribution
907 files to PyPI.
908
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000909- distutils.commands.register now encodes the data as UTF-8 before posting
910 them to PyPI.
911
Raymond Hettinger267b8682005-03-27 10:47:39 +0000912- decimal operator and comparison methods now return NotImplemented
913 instead of raising a TypeError when interacting with other types. This
914 allows other classes to implement __radd__ style methods and have them
915 work as expected.
916
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000917- Bug #1163325: Decimal infinities failed to hash. Attempting to
918 hash a NaN raised an InvalidOperation instead of a TypeError.
919
Tim Petersecc6e6a2005-07-10 22:30:55 +0000920- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +0000921 stream compression; add, for symmetry reasons, r:* as a synonym of r.

Raymond Hettingerbab41432005-02-05 01:31:19 +0000953- Fixed bug in a NameError bug in cookielib. Patch #1116583.
954
Guido van Rossumd0641422005-02-03 15:01:24 +0000955- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
956 disables recursive traversal through instance attributes, which can
957 be exploited in various ways.
958
Tim Peterse3547fd2005-12-16 23:13:57 +0000959- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000960 flags on the HTTP listening socket.
961
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000962- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
963 Fixed by reading the HTTP body in chunks instead of one big socket.read().
964
Tim Peterse3547fd2005-12-16 23:13:57 +0000965- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000966 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
967

969
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000970- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
971
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000972- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
973
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000974- Enhancements to the csv module:
975
976 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000977 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000978 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000979 + Dialect parameter parsing has been re-implemented to improve error
980 reporting.
981 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
982 dictates.
983 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000984 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +0000985 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000986 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
987 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000988 + reader now allows \r characters to be quoted (previously it only allowed
989 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +0000990 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000991 + Dialect classes passed to the module are no longer instantiated by
992 the module before being parsed (the former validation scheme required
993 this, but the mechanism was unreliable).
994 + The dialect registry now contains instances of the internal
995 C-coded dialect type, rather than references to python objects.
996 + the internal c-coded dialect type is now immutable.
997 + register_dialect now accepts the same keyword dialect specifications
998 as the reader and writer, allowing the user to register dialects
999 without first creating a dialect class.
1000 + a configurable limit to the size of parsed fields has been added -
1001 previously, an unmatched quote character could result in the entire
1002 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001003 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001004 the parser field size limit (returning the former limit). The initial
1005 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001006 + A line_num attribute has been added to the reader object, which tracks
1007 the number of lines read from the source iterator. This is not
1008 the same as the number of records returned, as records can span
1009 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001010 + reader and writer objects were not being registered with the cyclic-GC.
1011 This has been fixed.
1012
Brett Cannone6539c42005-01-08 02:43:53 +00001013- _DummyThread objects in the threading module now delete self.__block that is
1014 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1015 lock primitives tend to be limited in number and thus should not be wasted on
1016 a _DummyThread object. Fixes bug #1089632.
1017
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001018- The imghdr module now detects Exif files.
1019
Raymond Hettinger6065d322004-12-20 23:51:53 +00001020- StringIO.truncate() now correctly adjusts the size attribute.
1021 (Bug #951915).
1022
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001023- locale.py now uses an updated locale alias table (built using
1024 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1025 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001026 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001027
Raymond Hettinger3557f422004-12-07 12:02:02 +00001028- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1029
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001030- the pickle module no longer accepts the deprecated None option in the
1031 args tuple returned by __reduce__().
1032
Brett Cannon84667c02004-12-07 03:25:18 +00001033- optparse now optionally imports gettext. This allows its use in setup.py.
1034
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001035- the pickle module no longer uses the deprecated bin parameter.
1036
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001037- the shelve module no longer uses the deprecated binary parameter.
1038
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001039- the pstats module no longer uses the deprecated ignore() method.
1040
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001041- the filecmp module no longer uses the deprecated use_statcache argument.
1042
Raymond Hettinger664347b2004-12-04 21:21:53 +00001043- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1044 extended or overridden by subclasses. Formerly, the subclassed method would
1045 be ignored by the rest of the module. (Bug #1078905).
1046
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001047- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001048 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001049
Walter Dörwald36733692004-12-22 12:50:50 +00001050- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1051 once when a size argument is given. This prevents a buffer overflow in the
1052 tokenizer with very long source lines.
1053
Barry Warsaw538561e2006-01-01 21:48:54 +00001054- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1055 immediately after creating the object, without any intervening
1056 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001057
Skip Montanaro05885812005-01-16 20:48:27 +00001058- The reconvert.quote function can now emit triple-quoted strings. The
1059 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001060
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001061- ``UserString.MutableString`` now supports negative indices in
1062 ``__setitem__`` and ``__delitem__``
1063
Greg Ward40407942005-03-05 02:53:17 +00001064- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1065 correctly.
1066
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001067- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1068 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1069 character even if the user has passed a size parameter to get a proper
1070 line ending. Remove the special handling of a "\r\n" that has been split
1071 between two lines.
1072
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001073- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1074 about illegal code points. The codec now supports PEP 293 style error
1075 handlers.
1076
Walter Dörwald78a78b02005-09-01 12:04:29 +00001077- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001078 from the input stream, so that the output is a byte string in the correct
1079 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001080
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001081- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1082 considering it exactly like a '*'.
1083
Walter Dörwald007f8df2005-10-09 19:42:27 +00001084- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1085 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001086
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001087- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1088
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001089- Patch #1413711: Certain patterns of differences were making difflib
1090 touch the recursion limit.
1091
Walter Dörwald58917a62006-03-31 15:26:22 +00001092- Bug #947906: An object oriented interface has been added to the calendar
1093 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001094 called as a script (e.g. via ``python -mcalendar``). Localized month and
1095 weekday names can be ouput (even if an exotic encoding is used) using
1096 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001097

Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001115- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1116
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001117- Bug #1189330: configure did not correctly determine the necessary
1118 value of LINKCC if python was built with GCC 4.0.
1119
Trent Mick8321b422005-07-26 02:29:21 +00001120- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1121 vulnerability in zlib 1.2.1 and 1.2.2.
1122
Brett Cannon08cd5982005-04-24 22:26:38 +00001123- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1124 flags that change binary compatibility. Changes were also made to
1125 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001126 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001127
Bob Ippolitoed233462005-03-29 13:47:59 +00001128- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1129 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1130 no longer exists). This configure patch makes things right.
1131
Martin v. Löwise2713be2005-03-08 15:03:08 +00001132- Bug #1158607: Build with --disable-unicode again.
1133
Brett Cannon46d96232005-02-16 00:07:19 +00001134- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1135 defined. Discovered as a result of not being able to build on OS X.
1136
Brett Cannon516592f2004-12-07 00:42:59 +00001137- setup.py now uses the directories specified in LDFLAGS using the -L option
1138 and in CPPFLAGS using the -I option for adding library and include
1139 directories, respectively, for compiling extension modules against. This has
1140 led to the core being compiled using the values in CPPFLAGS. It also removes
1141 the need for the special-casing of both DarwinPorts and Fink for darwin since
1142 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1143 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1144 Fink, ``-I/opt/local/include`` for DarwinPorts).
1145
Brett Cannon43802422005-02-10 20:48:03 +00001146- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1147 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1148 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1149 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001151C API
1152-----
1153
Tim Petersc9d78aa2006-03-26 23:27:58 +00001154- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1155 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1156 is obtained via the ``PyObject_`` family, it must be released via the
1157 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1158 always been officially true, but when Python's small-object allocator was
1159 introduced, an attempt was made to cater to a few extension modules
1160 discovered at the time that obtained memory via ``PyObject_New`` but
1161 released it via ``PyMem_DEL``. It's years later, and if such code still
1162 exists it will fail now (probably with segfaults, but calling wrong
1163 low-level memory management functions can yield many symptoms).
1164
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001165- Added a C API for set and frozenset objects.
1166

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001169- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1170 mapping argument now. This string is used as a mapping table. Byte values
1171 greater than the length of the string and 0xFFFE are treated as undefined
1172 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001180- Patch #1276356: New resource "urlfetch" is implemented. This enables
1181 even impatient people to run tests that require remote files.
