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

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 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
Greg Wardab05edc2006-04-23 03:47:58 +000089- Updated optparse module to Optik 1.5.1 (allow numeric constants in
90 hex, octal, or binary; add ``append_const`` action; keep going if
91 gettext cannot be imported; added ``OptionParser.destroy()`` method;
92 added ``epilog`` for better help generation).
93
Tim Peters21fbd572006-04-21 21:18:10 +000094- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
95 called from a thread spawned as a side effect of importing a module.
96
Phillip J. Eby17a35f92006-04-18 16:45:14 +000097- New modules: setuptools, easy_install, and pkg_resources, to support
98 building, installing, and using Python eggs, respectively.
99
100- The pydoc module now supports documenting packages contained in
101 .zip or .egg files.
102
103- The pkgutil module now has several new utility functions, such
104 as ``walk_packages()`` to support working with packages that are either
105 in the filesystem or zip files.
106
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000107- The mailbox module can now modify and delete messages from
108 mailboxes, in addition to simply reading them. Thanks to Gregory
109 K. Johnson for writing the code, and to the 2005 Google Summer of
110 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000111
Tim Petersc7605f22006-04-17 21:12:33 +0000112- The ``__del__`` method of class ``local`` in module ``_threading_local``
113 returned before accomplishing any of its intended cleanup.
114
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000115- Patch #790710: Add breakpoint command lists in pdb.
116
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000117- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000119- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
120
Anthony Baxtere29002c2006-04-12 12:07:31 +0000121- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
122 Windows. Bug #1469163.
123
Phillip J. Eby47032112006-04-11 01:07:43 +0000124- The warnings, linecache, inspect, traceback, site, and doctest modules
125 were updated to work correctly with modules imported from zipfiles or
126 via other PEP 302 __loader__ objects.
127
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000128- Patch #1467770: Reduce usage of subprocess._active to processes which
129 the application hasn't waited on.
130

134
Skip Montanaro262fb922006-04-21 02:31:07 +0000135- The pstats.Stats class accepts an optional stream keyword argument to
136 direct output to an alternate file-like object.
137
Anthony Baxter51bcb682006-04-05 14:51:42 +0000138Build
139-----
140
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000141- The Makefile now has a reindent target, which runs reindent.py on
142 the library.
143
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000144- Patch #1470875: Building Python with MS Free Compiler
145
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000146- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000147
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000148- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
149 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000150 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000151 CXX from --with-cxx-main, see description in README.
152
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000153- Patch #1429775: Link extension modules with the shared libpython.

160
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000161- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
162 it separately and by hand. It also wasn't cleaning up its changes to
163 the current Decimal context.

172-------------
173
Tim Peters8dc73d22006-04-24 02:03:16 +0000174- Bug #1337990: clarified that ``doctest`` does not support examples
175 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000178What's New in Python 2.5 alpha 1?
179=================================
180
Anthony Baxterebed3f62006-04-03 15:03:44 +0000181*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000182
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000183Core and builtins
184-----------------
185
Nick Coghlan43832302006-04-23 17:04:07 +0000186- PEP 338: -m command line switch now delegates to runpy.run_module
187 allowing it to support modules in packages and zipfiles
188
Martin v. Löwisc661b882006-04-20 04:54:23 +0000189- On Windows, .DLL is not an accepted file name extension for
190 extension modules anymore; extensions are only found if they
191 end in .PYD.
192
Martin v. Löwisea62d252006-04-03 10:56:49 +0000193- Bug #1421664: sys.stderr.encoding is now set to the same value as
194 sys.stdout.encoding.
195
Neal Norwitz92e212f2006-04-03 04:48:37 +0000196- __import__ accepts keyword arguments.
197
Georg Brandlccadf842006-03-31 18:54:53 +0000198- Patch #1460496: round() now accepts keyword arguments.
199
Anthony Baxter262c00a2006-03-30 10:53:17 +0000200- Fixed bug #1459029 - unicode reprs were double-escaped.
201
Hye-Shik Changd478f342006-03-23 12:32:36 +0000202- Patch #1396919: The system scope threads are reenabled on FreeBSD
203 5.4 and later versions.
204
Neal Norwitze98ccf62006-03-23 05:39:47 +0000205- Bug #1115379: Compiling a Unicode string with an encoding declaration
206 now gives a SyntaxError.
207
Georg Brandlabd1ff82006-03-18 07:59:59 +0000208- Previously, Python code had no easy way to access the contents of a
209 cell object. Now, a ``cell_contents`` attribute has been added
210 (closes patch #1170323).
211
Tim Peterscf79aac2006-03-16 01:14:46 +0000212- Patch #1123430: Python's small-object allocator now returns an arena to
213 the system ``free()`` when all memory within an arena becomes unused
214 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
215 freed. Some applications will see a drop in virtual memory size now,
216 especially long-running applications that, from time to time, temporarily
217 use a large number of small objects. Note that when Python returns an
218 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000219 platform C library will in turn return that memory to the operating system.
220 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000221 appears to be effective at least on Microsoft C and gcc-based systems.
222 Thanks to Evan Jones for hard work and patience.
223
Georg Brandl533ff6f2006-03-08 18:09:27 +0000224- Patch #1434038: property() now uses the getter's docstring if there is
225 no "doc" argument given. This makes it possible to legitimately use
226 property() as a decorator to produce a read-only property.
227
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000228- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
229 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
230 of requiring an int or long in slicing and a few other contexts, enabling
231 other objects (e.g. Numeric Python's integers) to be used as slice indices.
232
Neal Norwitz995acdf2006-03-07 05:01:00 +0000233- Fixed various bugs reported by Coverity's Prevent tool.
234
Brett Cannonbf364092006-03-01 04:25:17 +0000235- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
236 new exception base class, BaseException, which has a new message attribute.
237 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
238 Raising a string exception now raises a DeprecationWarning.
239
Thomas Woutersfb609f42006-02-28 16:37:25 +0000240- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
241 explicitly relative, using 'from .module import name' to mean 'from the same
242 package as this module is in. Imports without dots still default to the
243 old relative-then-absolute, unless 'from __future__ import
244 absolute_import' is used.
245
Brett Cannona7446e32006-02-27 23:39:10 +0000246- Properly check if 'warnings' raises an exception (usually when a filter set
247 to "error" is triggered) when raising a warning for raising string
248 exceptions.
249
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000250- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000251 The name was removed from Include/code.h.
252
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000253- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000254
Guido van Rossum1968ad32006-02-25 22:38:04 +0000255- Patch 1433928:
256 - The copy module now "copies" function objects (as atomic objects).
257 - dict.__getitem__ now looks for a __missing__ hook before raising
258 KeyError.
259
Tim Peters84ef21c2006-02-28 20:39:06 +0000260- PEP 343: with statement implemented. Needs ``from __future__ import
261 with_statement``. Use of 'with' as a variable will generate a warning.
262 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000263 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000264 The following objects have __context__ methods:
265 - The built-in file type.
266 - The thread.LockType type.
267 - The following types defined by the threading module:
268 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
269 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000270
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000271- Fix the encodings package codec search function to only search
272 inside its own package. Fixes problem reported in patch #1433198.
273
274 Note: Codec packages should implement and register their own
275 codec search function. PEP 100 has the details.
276
Martin v. Löwis18e16552006-02-15 17:27:45 +0000277- PEP 353: Using ssize_t as the index type.
278
Neal Norwitzfc76d632006-01-10 06:03:13 +0000279- Patch #1400181, fix unicode string formatting to not use the locale.
280 This is how string objects work. u'%f' could use , instead of .
281 for the decimal point. Now both strings and unicode always use periods.
282
Neal Norwitz671b9e32006-01-09 07:07:12 +0000283- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
284 configure would break checking curses.h.
285
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000286- Bug #959576: The pwd module is now builtin. This allows Python to be
287 built on UNIX platforms without $HOME set.
288
Neal Norwitzc10978f2005-12-19 06:07:16 +0000289- Bug #1072182, fix some potential problems if characters are signed.
290
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000291- Bug #889500, fix line number on SyntaxWarning for global declarations.
292
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000293- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
294
Neal Norwitze7214a12005-12-18 05:03:17 +0000295- Support for converting hex strings to floats no longer works.
296 This was not portable. float('0x3') now raises a ValueError.
297
Barry Warsaw2a38a862005-12-18 01:27:35 +0000298- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000299 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000300 is now displayed in interactive prompt banner.
301
Georg Brandlfa166682005-12-17 21:45:17 +0000302- Implementation of PEP 341 - Unification of try/except and try/finally.
303 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000304 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000305
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000306- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
307 now encodes backslash correctly.
308
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000309- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
310
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000311- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000312 and long longs.
313
Neal Norwitz67715f02005-11-09 06:59:35 +0000314- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000315 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000316 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000317
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000318- Replaced most Unicode charmap codecs with new ones using the
319 new Unicode translate string feature in the builtin charmap
320 codec; the codecs were created from the mapping tables available
321 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
322 encodings now include a mapping for the Apple logo)
323
Tim Peterse3547fd2005-12-16 23:13:57 +0000324- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000325
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000326- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000327
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000328- A new AST parser implementation was completed. The abstract
329 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000330 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000331
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000332- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000333 The following code now raises a SyntaxError: foo(a = i for i in range(10))
334
Neal Norwitz708e51a2005-10-03 04:48:15 +0000335- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
336
Neal Norwitz11bd1192005-10-03 00:54:56 +0000337- SF Bug #887946: fix segfault when redirecting stdin from a directory.
338 Provide a warning when a directory is passed on the command line.
339
Neal Norwitz40d37812005-10-02 01:48:49 +0000340- Fix segfault with invalid coding.
341
342- SF bug #772896: unknown encoding results in MemoryError.
343
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000344- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000345 supported a __len__() method which evaluated to False when the iterator
346 was empty.
347
Guido van Rossum630db602005-09-20 18:49:54 +0000348- On 64-bit platforms, when __len__() returns a value that cannot be
349 represented as a C int, raise OverflowError.
350
Skip Montanarof8948ca2005-09-19 03:54:46 +0000351- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000352 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000353
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000354- SF bug #893549: parsing keyword arguments was broken with a few format
355 codes.
356
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000357- Changes donated by Elemental Security to make it work on AIX 5.3
358 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
359 bug #105470: test_pwd fails on 64bit system (Opteron).
360
Guido van Rossum539c6622005-09-14 17:49:54 +0000361- Changes donated by Elemental Security to make it work on HP-UX 11 on
362 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
363
Georg Brandl4550b8d2005-08-26 06:43:52 +0000364- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000365 (fixes bug #1119418).
366
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000367- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
368
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000369- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
370 exceptions that cause a function to exit.
371
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000372- The implementation of set() and frozenset() was revised to use its
373 own internal data structure. Memory consumption is reduced by 1/3
374 and there are modest speed-ups as well. The API is unchanged.
375
Tim Petersde7990b2005-07-17 23:45:23 +0000376- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
377
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000378- SF bug #1229429: PyObject_CallMethod failed to decrement some
379 reference counts in some error exit cases.
380
Tim Petersecc6e6a2005-07-10 22:30:55 +0000381- SF bug #1185883: Python's small-object memory allocator took over
382 a block managed by the platform C library whenever a realloc specified
383 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000384 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000385 portable way to copy data from the C-managed block into Python's
386 small-object space without risking a memory fault. Python's small-object
387 realloc now leaves such blocks under the control of the platform C
388 realloc.
389
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000390- SF bug #1232517: An overflow error was not detected properly when
391 attempting to convert a large float to an int in os.utime().
392
Raymond Hettinger3296e692005-06-29 23:29:56 +0000393- SF bug #1224347: hex longs now print with lowercase letters just
394 like their int counterparts.
395
Michael W. Hudson188d4362005-06-20 16:52:57 +0000396- SF bug #1163563: the original fix for bug #1010677 ("thread Module
397 Breaks PyGILState_Ensure()") broke badly in the case of multiple
398 interpreter states; back out that fix and do a better job (see
399 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
400 for a longer write-up of the problem).
401
Michael W. Hudsondf888462005-06-03 14:41:55 +0000402- SF patch #1180995: marshal now uses a binary format by default when
403 serializing floats.
404
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000405- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
406 the routines that promise to produce IEEE 754 binary representations
407 of floats now simply copy bytes around.
408
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000409- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
410 278.
411
Brett Cannonc3647ac2005-04-26 03:45:26 +0000412- patch #1109424: int, long, float, complex, and unicode now check for the
413 proper magic slot for type conversions when subclassed. Previously the
414 magic slot was ignored during conversion. Semantics now match the way
415 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000416 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000417 PyNumber_*().
418 Thanks Walter Dörwald.
419
Barry Warsawc8d907c2005-04-19 23:43:40 +0000420- Descriptors defined in C with a PyGetSetDef structure, where the setter is
421 NULL, now raise an AttributeError when attempting to set or delete the
422 attribute. Previously a TypeError was raised, but this was inconsistent
423 with the equivalent pure-Python implementation.
424
Michael W. Hudson774479c2005-04-18 08:46:17 +0000425- It is now safe to call PyGILState_Release() before
426 PyEval_InitThreads() (note that if there is reason to believe there
427 are multiple threads around you still must call PyEval_InitThreads()
428 before using the Python API; this fix is for extension modules that
429 have no way of knowing if Python is multi-threaded yet).
430
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000431- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
432 disabled caused a crash.
433
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000434- Bug #1165306: instancemethod_new allowed the creation of a method
435 with im_class == im_self == NULL, which caused a crash when called.
436
Tim Petersecc6e6a2005-07-10 22:30:55 +0000437- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000438 fixes the crash seen in bug #1165761
439
Raymond Hettinger96229b12005-03-11 06:49:40 +0000440- Added two new builtins, any() and all().
441
Brett Cannon409d8f22005-03-05 06:47:57 +0000442- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000443 (e.g., ``class C(): pass`` is no longer a syntax error).
444 Patch #1176012 added support to the 'parser' module and 'compiler' package
445 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000446
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000447- Patch #1115086: Support PY_LONGLONG in structmember.
448
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000449- Bug #1155938: new style classes did not check that __init__() was
450 returning None.
451
Tim Petersecc6e6a2005-07-10 22:30:55 +0000452- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000453 ('\') with a specific error message.
454
Martin v. Löwisff232d72005-03-03 09:24:38 +0000455- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
456
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000457- Bug #1124295: the __name__ attribute of file objects was
458 inadvertently made inaccessible in restricted mode.
459
Tim Petersecc6e6a2005-07-10 22:30:55 +0000460- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000461 an ferror() call.
462
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000463- min() and max() now support key= arguments with the same meaning as in
464 list.sort().
465
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000466- The peephole optimizer now performs simple constant folding in expressions:
467 (2+3) --> (5).
468
Raymond Hettingera422c342005-01-11 03:03:27 +0000469- set and frozenset objects can now be marshalled. SF #1098985.
470
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000471- Bug #1077106: Poor argument checking could cause memory corruption
472 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000473
Jeremy Hyltonab630502005-02-04 18:44:06 +0000474- The parser did not complain about future statements in illegal
475 positions. It once again reports a syntax error if a future
476 statement occurs after anything other than a doc string.
477
Neil Schemenauercf52c072005-08-12 17:34:58 +0000478- Change the %s format specifier for str objects so that it returns a
479 unicode instance if the argument is not an instance of basestring and
480 calling __str__ on the argument returns a unicode instance.
481
Tim Petersf4e69282006-02-27 17:15:31 +0000482- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
483 current thread state when the auto-GIL-state machinery knows about
484 it (since the thread state is being deleted, continuing to remember it
485 can't help, but can hurt if another thread happens to get created with
486 the same thread id).
487
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000488Extension Modules

505
506- The following modules were removed: regsub, reconvert, regex, regex_syntax.
507
508- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000509 is deprecated. The undocumented re.engine variable no longer exists.
510
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000511- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
512 SS2 (single-shift 2) escape sequences correctly.
513
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000514- The unicodedata module was updated to the 4.1 version of the Unicode
515 database. The 3.2 version is still available as unicodedata.db_3_2_0
516 for applications that require this specific version (such as IDNA).
517
Neal Norwitzb62c4332006-03-04 18:35:47 +0000518- The timing module is no longer built by default. It was deprecated
519 in PEP 4 in Python 2.0 or earlier.
520
Guido van Rossum1968ad32006-02-25 22:38:04 +0000521- Patch 1433928: Added a new type, defaultdict, to the collections module.
522 This uses the new __missing__ hook behavior added to dict (see above).
523
Georg Brandldbd83392006-02-20 09:42:33 +0000524- Bug #854823: socketmodule now builds on Sun platforms even when
525 INET_ADDRSTRLEN is not defined.
526
Georg Brandlf4f44152006-02-18 22:29:33 +0000527- Patch #1393157: os.startfile() now has an optional argument to specify
528 a "command verb" to invoke on the file.
529
Neal Norwitz082b2df2006-02-07 07:04:46 +0000530- Bug #876637, prevent stack corruption when socket descriptor
531 is larger than FD_SETSIZE.
532
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000533- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
534 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
535 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
536
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000537- Patch #1422385: The nis module now supports access to domains other
538 than the system default domain.
539
Martin v. Löwis14694662006-02-03 12:54:16 +0000540- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
541 are reported, the limit on path name lengths is removed, and stat reports
542 WindowsError now (instead of OSError).
543
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000544- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000675Library
676-------
677
Nick Coghlan43832302006-04-23 17:04:07 +0000678- PEP 338: new module runpy defines a run_module function to support
679 executing modules which provide access to source code or a code object
680 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000693 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000694 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000695 module will not be built.
696
Tim Petersc17976e2006-04-01 00:26:53 +0000697- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
698 aren't officially supported here, and trying to use them will probably
699 raise an exception some day. But dicts have been allowed, and "mostly
700 worked", so support for them won't go away without warning.
701
Georg Brandl338ef7d2006-03-31 18:42:16 +0000702- Bug #1445068: getpass.getpass() can now be given an explicit stream

704
Georg Brandl22ec80b2006-03-31 18:25:44 +0000705- Patch #1462313, bug #1443328: the pickle modules now can handle classes

720
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000721- email 4.0 package now integrated. This is largely the same as the email 3.0
722 package that was included in Python 2.3, except that PEP 8 module names are
723 now used (e.g. mail.message instead of email.Message). The MIME classes
724 have been moved to a subpackage (e.g. email.mime.text instead of
725 email.MIMEText). The old names are still supported for now. Several
726 deprecated Message methods have been removed and lots of bugs have been
727 fixed. More details can be found in the email package documentation.
728
Walter Dörwald40108c92006-03-27 08:15:44 +0000729- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
730 (a subclass of tuple) that provides incremental decoders and encoders
731 (a way to use stateful codecs without the stream API). Python functions
732 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
733 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
734 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000735
Walter Dörwald067db482006-03-15 22:17:27 +0000736- Patch #1359365: Calling next() on a closed StringIO.String object raises
737 a ValueError instead of a StopIteration now (like file and cString.String do).
738 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
739 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000740

751
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000752- PEP 343: new module contextlib.py defines decorator @contextmanager
753 and helpful context managers nested() and closing().
754
Martin v. Löwis415ed932006-02-27 19:56:30 +0000755- The compiler package now supports future imports after the module docstring.

767 current file number.
768

814 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
815 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
816 Ronald L. Rivest offered this advice for Python:
817
818 "The consensus of researchers in this area (at least as
819 expressed at the NIST Hash Function Workshop 10/31/05),
820 is that SHA-256 is a good choice for the time being, but
821 that research should continue, and other alternatives may
822 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000823
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000824- Added a subset of Fredrik Lundh's ElementTree package. Available

872 match the Content-Length header.
873
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +0000874- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
875
Martin v. Löwis56066d22005-08-24 07:38:12 +0000876- Bug #1178484: Return complete lines from codec stream readers
877 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000878 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +0000879

893
Georg Brandla4a8b822005-07-15 09:13:21 +0000894- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
895 parameter, but uses the usual "kwargs=None".
896
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000897- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +0000898 Patch #1209527 (Contributed by Connelly).
899
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000900- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
901 to W3C name (404 -> 'Not Found'). RFE #1216944.
902
Georg Brandl9e43acf2005-07-04 17:16:07 +0000903- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
904 as this can cause problems with apps closing all file descriptors.

917 Bug #1224621.
918
Raymond Hettinger68c04532005-06-10 11:05:19 +0000919- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000920 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000921 the generate_tokens() function now accepts a callable argument that
922 terminates by raising StopIteration.
923
Georg Brandl9166e1a2005-06-04 09:20:03 +0000924- Bug #1196315: fix weakref.WeakValueDictionary constructor.

927 component of the path.
928
Skip Montanaro174dd222005-05-14 20:54:16 +0000929- Patch #1120353: The xmlrpclib module provides better, more transparent,
930 support for datetime.{datetime,date,time} objects. With use_datetime set
931 to True, applications shouldn't have to fiddle with the DateTime wrapper
932 class at all.
933
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000934- distutils.commands.upload was added to support uploading distribution

938 them to PyPI.
939
Raymond Hettinger267b8682005-03-27 10:47:39 +0000940- decimal operator and comparison methods now return NotImplemented
941 instead of raising a TypeError when interacting with other types. This
942 allows other classes to implement __radd__ style methods and have them
943 work as expected.
944
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000945- Bug #1163325: Decimal infinities failed to hash. Attempting to
946 hash a NaN raised an InvalidOperation instead of a TypeError.
947

982
Guido van Rossumd0641422005-02-03 15:01:24 +0000983- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
984 disables recursive traversal through instance attributes, which can
985 be exploited in various ways.
986
Tim Peterse3547fd2005-12-16 23:13:57 +0000987- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000988 flags on the HTTP listening socket.
989
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000990- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
991 Fixed by reading the HTTP body in chunks instead of one big socket.read().
992
Tim Peterse3547fd2005-12-16 23:13:57 +0000993- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000994 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
995
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000996- Bug #1110478: Revert os.environ.update to do putenv again.
997
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000998- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
999
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001000- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1001
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001002- Enhancements to the csv module:
1003
1004 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001005 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001006 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001007 + Dialect parameter parsing has been re-implemented to improve error
1008 reporting.
1009 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1010 dictates.
1011 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001012 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001013 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001014 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1015 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001016 + reader now allows \r characters to be quoted (previously it only allowed
1017 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001018 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001019 + Dialect classes passed to the module are no longer instantiated by
1020 the module before being parsed (the former validation scheme required
1021 this, but the mechanism was unreliable).
1022 + The dialect registry now contains instances of the internal
1023 C-coded dialect type, rather than references to python objects.
1024 + the internal c-coded dialect type is now immutable.
1025 + register_dialect now accepts the same keyword dialect specifications
1026 as the reader and writer, allowing the user to register dialects
1027 without first creating a dialect class.
1028 + a configurable limit to the size of parsed fields has been added -
1029 previously, an unmatched quote character could result in the entire
1030 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001031 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001032 the parser field size limit (returning the former limit). The initial
1033 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001034 + A line_num attribute has been added to the reader object, which tracks
1035 the number of lines read from the source iterator. This is not
1036 the same as the number of records returned, as records can span
1037 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001038 + reader and writer objects were not being registered with the cyclic-GC.
1039 This has been fixed.
1040
Brett Cannone6539c42005-01-08 02:43:53 +00001041- _DummyThread objects in the threading module now delete self.__block that is
1042 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1043 lock primitives tend to be limited in number and thus should not be wasted on
1044 a _DummyThread object. Fixes bug #1089632.
1045
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001046- The imghdr module now detects Exif files.
1047
Raymond Hettinger6065d322004-12-20 23:51:53 +00001048- StringIO.truncate() now correctly adjusts the size attribute.
1049 (Bug #951915).
1050
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001051- locale.py now uses an updated locale alias table (built using
1052 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1053 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001054 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001055
Raymond Hettinger3557f422004-12-07 12:02:02 +00001056- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1057
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001058- the pickle module no longer accepts the deprecated None option in the
1059 args tuple returned by __reduce__().
1060
Brett Cannon84667c02004-12-07 03:25:18 +00001061- optparse now optionally imports gettext. This allows its use in setup.py.
1062
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001063- the pickle module no longer uses the deprecated bin parameter.
1064
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001065- the shelve module no longer uses the deprecated binary parameter.
1066
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001067- the pstats module no longer uses the deprecated ignore() method.
1068
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001069- the filecmp module no longer uses the deprecated use_statcache argument.
1070
Raymond Hettinger664347b2004-12-04 21:21:53 +00001071- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1072 extended or overridden by subclasses. Formerly, the subclassed method would
1073 be ignored by the rest of the module. (Bug #1078905).
1074
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001075- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001076 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001077
Walter Dörwald36733692004-12-22 12:50:50 +00001078- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1079 once when a size argument is given. This prevents a buffer overflow in the
1080 tokenizer with very long source lines.
1081
Barry Warsaw538561e2006-01-01 21:48:54 +00001082- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1083 immediately after creating the object, without any intervening
1084 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001085
Skip Montanaro05885812005-01-16 20:48:27 +00001086- The reconvert.quote function can now emit triple-quoted strings. The
1087 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001088
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001089- ``UserString.MutableString`` now supports negative indices in
1090 ``__setitem__`` and ``__delitem__``
1091
Greg Ward40407942005-03-05 02:53:17 +00001092- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1093 correctly.
1094
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001095- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1096 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1097 character even if the user has passed a size parameter to get a proper
1098 line ending. Remove the special handling of a "\r\n" that has been split
1099 between two lines.
1100
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001101- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1102 about illegal code points. The codec now supports PEP 293 style error
1103 handlers.
1104
Walter Dörwald78a78b02005-09-01 12:04:29 +00001105- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001106 from the input stream, so that the output is a byte string in the correct
1107 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001108
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001109- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1110 considering it exactly like a '*'.
1111
Walter Dörwald007f8df2005-10-09 19:42:27 +00001112- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1113 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001114
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001115- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1116
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001117- Patch #1413711: Certain patterns of differences were making difflib
1118 touch the recursion limit.
1119
Walter Dörwald58917a62006-03-31 15:26:22 +00001120- Bug #947906: An object oriented interface has been added to the calendar
1121 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001122 called as a script (e.g. via ``python -mcalendar``). Localized month and
1123 weekday names can be ouput (even if an exotic encoding is used) using
1124 special classes that use unicode.

1133
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001134- Build support for Win64-AMD64 was added.
1135

1137
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001138- Patch #881820: look for openpty and forkpty also in libbsd.
1139
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001140- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1141 The zlib module is now builtin on Windows.
1142
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001143- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1144
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001145- Bug #1189330: configure did not correctly determine the necessary
1146 value of LINKCC if python was built with GCC 4.0.
1147
Trent Mick8321b422005-07-26 02:29:21 +00001148- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1149 vulnerability in zlib 1.2.1 and 1.2.2.
1150
Brett Cannon08cd5982005-04-24 22:26:38 +00001151- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1152 flags that change binary compatibility. Changes were also made to
1153 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001154 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001155
Bob Ippolitoed233462005-03-29 13:47:59 +00001156- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1157 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1158 no longer exists). This configure patch makes things right.
1159
Martin v. Löwise2713be2005-03-08 15:03:08 +00001160- Bug #1158607: Build with --disable-unicode again.
1161
Brett Cannon46d96232005-02-16 00:07:19 +00001162- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1163 defined. Discovered as a result of not being able to build on OS X.
1164
Brett Cannon516592f2004-12-07 00:42:59 +00001165- setup.py now uses the directories specified in LDFLAGS using the -L option
1166 and in CPPFLAGS using the -I option for adding library and include
1167 directories, respectively, for compiling extension modules against. This has
1168 led to the core being compiled using the values in CPPFLAGS. It also removes
1169 the need for the special-casing of both DarwinPorts and Fink for darwin since
1170 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1171 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1172 Fink, ``-I/opt/local/include`` for DarwinPorts).
1173
Brett Cannon43802422005-02-10 20:48:03 +00001174- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1175 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1176 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1177 Closes bug #1096244. Thanks Gregory Bond.

1180-----
1181
Tim Petersc9d78aa2006-03-26 23:27:58 +00001182- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1183 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1184 is obtained via the ``PyObject_`` family, it must be released via the
1185 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1186 always been officially true, but when Python's small-object allocator was
1187 introduced, an attempt was made to cater to a few extension modules
1188 discovered at the time that obtained memory via ``PyObject_New`` but
1189 released it via ``PyMem_DEL``. It's years later, and if such code still
1190 exists it will fail now (probably with segfaults, but calling wrong
1191 low-level memory management functions can yield many symptoms).
1192
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001193- Added a C API for set and frozenset objects.
1194

1196
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001197- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1198 mapping argument now. This string is used as a mapping table. Byte values
1199 greater than the length of the string and 0xFFFE are treated as undefined
1200 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001207
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001208- Patch #1276356: New resource "urlfetch" is implemented. This enables
1209 even impatient people to run tests that require remote files.
