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
Tim Peters21fbd572006-04-21 21:18:10 +000089- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
90 called from a thread spawned as a side effect of importing a module.
91
Phillip J. Eby17a35f92006-04-18 16:45:14 +000092- New modules: setuptools, easy_install, and pkg_resources, to support
93 building, installing, and using Python eggs, respectively.
94
95- The pydoc module now supports documenting packages contained in
96 .zip or .egg files.
97
98- The pkgutil module now has several new utility functions, such
99 as ``walk_packages()`` to support working with packages that are either
100 in the filesystem or zip files.
101
102
Tim Petersc7605f22006-04-17 21:12:33 +0000103- The ``__del__`` method of class ``local`` in module ``_threading_local``
104 returned before accomplishing any of its intended cleanup.
105
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000106- Patch #790710: Add breakpoint command lists in pdb.
107
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000108- Patch #1063914: Add Tkinter.Misc.clipboard_get().
109
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000110- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
111
Anthony Baxtere29002c2006-04-12 12:07:31 +0000112- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
113 Windows. Bug #1469163.
114
Phillip J. Eby47032112006-04-11 01:07:43 +0000115- The warnings, linecache, inspect, traceback, site, and doctest modules
116 were updated to work correctly with modules imported from zipfiles or
117 via other PEP 302 __loader__ objects.
118
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000119- Patch #1467770: Reduce usage of subprocess._active to processes which
120 the application hasn't waited on.
121
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000122- Patch #1462222: Fix Tix.Grid.

Neal Norwitza31bf182006-04-09 03:35:43 +0000124- Fix exception when doing glob.glob('anything*/')
125
Skip Montanaro262fb922006-04-21 02:31:07 +0000126- The pstats.Stats class accepts an optional stream keyword argument to
127 direct output to an alternate file-like object.
128
Anthony Baxter51bcb682006-04-05 14:51:42 +0000129Build
130-----
131
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000132- The Makefile now has a reindent target, which runs reindent.py on
133 the library.
134
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000135- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000138
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000139- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
140 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000141 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000142 CXX from --with-cxx-main, see description in README.
143
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000144- Patch #1429775: Link extension modules with the shared libpython.

151
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000152- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
153 it separately and by hand. It also wasn't cleaning up its changes to
154 the current Decimal context.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000167What's New in Python 2.5 alpha 1?
168=================================
169
Anthony Baxterebed3f62006-04-03 15:03:44 +0000170*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000171
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000172Core and builtins
173-----------------
174
Martin v. Löwisc661b882006-04-20 04:54:23 +0000175- On Windows, .DLL is not an accepted file name extension for
176 extension modules anymore; extensions are only found if they
177 end in .PYD.
178
Martin v. Löwisea62d252006-04-03 10:56:49 +0000179- Bug #1421664: sys.stderr.encoding is now set to the same value as
180 sys.stdout.encoding.
181
Neal Norwitz92e212f2006-04-03 04:48:37 +0000182- __import__ accepts keyword arguments.
183
Georg Brandlccadf842006-03-31 18:54:53 +0000184- Patch #1460496: round() now accepts keyword arguments.
185
Anthony Baxter262c00a2006-03-30 10:53:17 +0000186- Fixed bug #1459029 - unicode reprs were double-escaped.
187
Hye-Shik Changd478f342006-03-23 12:32:36 +0000188- Patch #1396919: The system scope threads are reenabled on FreeBSD
189 5.4 and later versions.
190
Neal Norwitze98ccf62006-03-23 05:39:47 +0000191- Bug #1115379: Compiling a Unicode string with an encoding declaration
192 now gives a SyntaxError.
193
Georg Brandlabd1ff82006-03-18 07:59:59 +0000194- Previously, Python code had no easy way to access the contents of a
195 cell object. Now, a ``cell_contents`` attribute has been added
196 (closes patch #1170323).
197
Tim Peterscf79aac2006-03-16 01:14:46 +0000198- Patch #1123430: Python's small-object allocator now returns an arena to
199 the system ``free()`` when all memory within an arena becomes unused
200 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
201 freed. Some applications will see a drop in virtual memory size now,
202 especially long-running applications that, from time to time, temporarily
203 use a large number of small objects. Note that when Python returns an
204 arena to the platform C's ``free()``, there's no guarantee that the
205 platform C will in turn return that memory to the operating system. The
206 effect of the patch is to stop making that impossible, and in tests it
207 appears to be effective at least on Microsoft C and gcc-based systems.
208 Thanks to Evan Jones for hard work and patience.
209
Georg Brandl533ff6f2006-03-08 18:09:27 +0000210- Patch #1434038: property() now uses the getter's docstring if there is
211 no "doc" argument given. This makes it possible to legitimately use
212 property() as a decorator to produce a read-only property.
213
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000214- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
215 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
216 of requiring an int or long in slicing and a few other contexts, enabling
217 other objects (e.g. Numeric Python's integers) to be used as slice indices.
218
Neal Norwitz995acdf2006-03-07 05:01:00 +0000219- Fixed various bugs reported by Coverity's Prevent tool.
220
Brett Cannonbf364092006-03-01 04:25:17 +0000221- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
222 new exception base class, BaseException, which has a new message attribute.
223 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
224 Raising a string exception now raises a DeprecationWarning.
225
Thomas Woutersfb609f42006-02-28 16:37:25 +0000226- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
227 explicitly relative, using 'from .module import name' to mean 'from the same
228 package as this module is in. Imports without dots still default to the
229 old relative-then-absolute, unless 'from __future__ import
230 absolute_import' is used.
231
Brett Cannona7446e32006-02-27 23:39:10 +0000232- Properly check if 'warnings' raises an exception (usually when a filter set
233 to "error" is triggered) when raising a warning for raising string
234 exceptions.
235
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000236- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000237 The name was removed from Include/code.h.
238
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000239- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000240
Guido van Rossum1968ad32006-02-25 22:38:04 +0000241- Patch 1433928:
242 - The copy module now "copies" function objects (as atomic objects).
243 - dict.__getitem__ now looks for a __missing__ hook before raising
244 KeyError.
245
Tim Peters84ef21c2006-02-28 20:39:06 +0000246- PEP 343: with statement implemented. Needs ``from __future__ import
247 with_statement``. Use of 'with' as a variable will generate a warning.
248 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000249 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000250 The following objects have __context__ methods:
251 - The built-in file type.
252 - The thread.LockType type.
253 - The following types defined by the threading module:
254 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
255 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000256
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000257- Fix the encodings package codec search function to only search
258 inside its own package. Fixes problem reported in patch #1433198.
259
260 Note: Codec packages should implement and register their own
261 codec search function. PEP 100 has the details.
262
Martin v. Löwis18e16552006-02-15 17:27:45 +0000263- PEP 353: Using ssize_t as the index type.
264
Neal Norwitzfc76d632006-01-10 06:03:13 +0000265- Patch #1400181, fix unicode string formatting to not use the locale.
266 This is how string objects work. u'%f' could use , instead of .
267 for the decimal point. Now both strings and unicode always use periods.
268
Neal Norwitz671b9e32006-01-09 07:07:12 +0000269- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
270 configure would break checking curses.h.
271
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000272- Bug #959576: The pwd module is now builtin. This allows Python to be
273 built on UNIX platforms without $HOME set.
274
Neal Norwitzc10978f2005-12-19 06:07:16 +0000275- Bug #1072182, fix some potential problems if characters are signed.
276
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000277- Bug #889500, fix line number on SyntaxWarning for global declarations.
278
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000279- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
280
Neal Norwitze7214a12005-12-18 05:03:17 +0000281- Support for converting hex strings to floats no longer works.
282 This was not portable. float('0x3') now raises a ValueError.
283
Barry Warsaw2a38a862005-12-18 01:27:35 +0000284- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000285 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000286 is now displayed in interactive prompt banner.
287
Georg Brandlfa166682005-12-17 21:45:17 +0000288- Implementation of PEP 341 - Unification of try/except and try/finally.
289 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000290 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000291
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000292- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
293 now encodes backslash correctly.
294
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000295- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
296
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000297- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000298 and long longs.
299
Neal Norwitz67715f02005-11-09 06:59:35 +0000300- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000301 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000302 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000303
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000304- Replaced most Unicode charmap codecs with new ones using the
305 new Unicode translate string feature in the builtin charmap
306 codec; the codecs were created from the mapping tables available
307 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
308 encodings now include a mapping for the Apple logo)

Tim Peterse3547fd2005-12-16 23:13:57 +0000310- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000311
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000312- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000313
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000314- A new AST parser implementation was completed. The abstract
315 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000316 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000317
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000318- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000319 The following code now raises a SyntaxError: foo(a = i for i in range(10))
320
Neal Norwitz708e51a2005-10-03 04:48:15 +0000321- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
322
Neal Norwitz11bd1192005-10-03 00:54:56 +0000323- SF Bug #887946: fix segfault when redirecting stdin from a directory.
324 Provide a warning when a directory is passed on the command line.
325
Neal Norwitz40d37812005-10-02 01:48:49 +0000326- Fix segfault with invalid coding.
327
328- SF bug #772896: unknown encoding results in MemoryError.
329
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000330- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000331 supported a __len__() method which evaluated to False when the iterator
332 was empty.
333
Guido van Rossum630db602005-09-20 18:49:54 +0000334- On 64-bit platforms, when __len__() returns a value that cannot be
335 represented as a C int, raise OverflowError.
336
Skip Montanarof8948ca2005-09-19 03:54:46 +0000337- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000338 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000339
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000340- SF bug #893549: parsing keyword arguments was broken with a few format
341 codes.
342
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000343- Changes donated by Elemental Security to make it work on AIX 5.3
344 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
345 bug #105470: test_pwd fails on 64bit system (Opteron).
346
Guido van Rossum539c6622005-09-14 17:49:54 +0000347- Changes donated by Elemental Security to make it work on HP-UX 11 on
348 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
349
Georg Brandl4550b8d2005-08-26 06:43:52 +0000350- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000351 (fixes bug #1119418).
352
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000353- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
354
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000355- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
356 exceptions that cause a function to exit.
357
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000358- The implementation of set() and frozenset() was revised to use its
359 own internal data structure. Memory consumption is reduced by 1/3
360 and there are modest speed-ups as well. The API is unchanged.
361
Tim Petersde7990b2005-07-17 23:45:23 +0000362- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
363
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000364- SF bug #1229429: PyObject_CallMethod failed to decrement some
365 reference counts in some error exit cases.
366
Tim Petersecc6e6a2005-07-10 22:30:55 +0000367- SF bug #1185883: Python's small-object memory allocator took over
368 a block managed by the platform C library whenever a realloc specified
369 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000370 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000371 portable way to copy data from the C-managed block into Python's
372 small-object space without risking a memory fault. Python's small-object
373 realloc now leaves such blocks under the control of the platform C
374 realloc.
375
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000376- SF bug #1232517: An overflow error was not detected properly when
377 attempting to convert a large float to an int in os.utime().
378
Raymond Hettinger3296e692005-06-29 23:29:56 +0000379- SF bug #1224347: hex longs now print with lowercase letters just
380 like their int counterparts.
381
Michael W. Hudson188d4362005-06-20 16:52:57 +0000382- SF bug #1163563: the original fix for bug #1010677 ("thread Module
383 Breaks PyGILState_Ensure()") broke badly in the case of multiple
384 interpreter states; back out that fix and do a better job (see
385 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
386 for a longer write-up of the problem).
387
Michael W. Hudsondf888462005-06-03 14:41:55 +0000388- SF patch #1180995: marshal now uses a binary format by default when
389 serializing floats.
390
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000391- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
392 the routines that promise to produce IEEE 754 binary representations
393 of floats now simply copy bytes around.
394
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000395- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
396 278.
397
Brett Cannonc3647ac2005-04-26 03:45:26 +0000398- patch #1109424: int, long, float, complex, and unicode now check for the
399 proper magic slot for type conversions when subclassed. Previously the
400 magic slot was ignored during conversion. Semantics now match the way
401 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000402 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000403 PyNumber_*().
404 Thanks Walter Dörwald.
405
Barry Warsawc8d907c2005-04-19 23:43:40 +0000406- Descriptors defined in C with a PyGetSetDef structure, where the setter is
407 NULL, now raise an AttributeError when attempting to set or delete the
408 attribute. Previously a TypeError was raised, but this was inconsistent
409 with the equivalent pure-Python implementation.
410
Michael W. Hudson774479c2005-04-18 08:46:17 +0000411- It is now safe to call PyGILState_Release() before
412 PyEval_InitThreads() (note that if there is reason to believe there
413 are multiple threads around you still must call PyEval_InitThreads()
414 before using the Python API; this fix is for extension modules that
415 have no way of knowing if Python is multi-threaded yet).
416
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000417- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
418 disabled caused a crash.
419
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000420- Bug #1165306: instancemethod_new allowed the creation of a method
421 with im_class == im_self == NULL, which caused a crash when called.
422
Tim Petersecc6e6a2005-07-10 22:30:55 +0000423- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000424 fixes the crash seen in bug #1165761
425
Raymond Hettinger96229b12005-03-11 06:49:40 +0000426- Added two new builtins, any() and all().
427
Brett Cannon409d8f22005-03-05 06:47:57 +0000428- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000429 (e.g., ``class C(): pass`` is no longer a syntax error).
430 Patch #1176012 added support to the 'parser' module and 'compiler' package
431 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000432
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000433- Patch #1115086: Support PY_LONGLONG in structmember.
434
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000435- Bug #1155938: new style classes did not check that __init__() was
436 returning None.
437
Tim Petersecc6e6a2005-07-10 22:30:55 +0000438- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000439 ('\') with a specific error message.
440
Martin v. Löwisff232d72005-03-03 09:24:38 +0000441- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
442
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000443- Bug #1124295: the __name__ attribute of file objects was
444 inadvertently made inaccessible in restricted mode.
445
Tim Petersecc6e6a2005-07-10 22:30:55 +0000446- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000447 an ferror() call.
448
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000449- min() and max() now support key= arguments with the same meaning as in
450 list.sort().
451
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000452- The peephole optimizer now performs simple constant folding in expressions:
453 (2+3) --> (5).
454
Raymond Hettingera422c342005-01-11 03:03:27 +0000455- set and frozenset objects can now be marshalled. SF #1098985.
456
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000457- Bug #1077106: Poor argument checking could cause memory corruption
458 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000459
Jeremy Hyltonab630502005-02-04 18:44:06 +0000460- The parser did not complain about future statements in illegal
461 positions. It once again reports a syntax error if a future
462 statement occurs after anything other than a doc string.
463
Neil Schemenauercf52c072005-08-12 17:34:58 +0000464- Change the %s format specifier for str objects so that it returns a
465 unicode instance if the argument is not an instance of basestring and
466 calling __str__ on the argument returns a unicode instance.
467
Tim Petersf4e69282006-02-27 17:15:31 +0000468- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
469 current thread state when the auto-GIL-state machinery knows about
470 it (since the thread state is being deleted, continuing to remember it
471 can't help, but can hurt if another thread happens to get created with
472 the same thread id).
473
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000474Extension Modules
475-----------------
476

491
492- The following modules were removed: regsub, reconvert, regex, regex_syntax.
493
494- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000495 is deprecated. The undocumented re.engine variable no longer exists.
496

498 SS2 (single-shift 2) escape sequences correctly.
499
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000500- The unicodedata module was updated to the 4.1 version of the Unicode
501 database. The 3.2 version is still available as unicodedata.db_3_2_0
502 for applications that require this specific version (such as IDNA).
503
Neal Norwitzb62c4332006-03-04 18:35:47 +0000504- The timing module is no longer built by default. It was deprecated
505 in PEP 4 in Python 2.0 or earlier.
506
Guido van Rossum1968ad32006-02-25 22:38:04 +0000507- Patch 1433928: Added a new type, defaultdict, to the collections module.
508 This uses the new __missing__ hook behavior added to dict (see above).
509
Georg Brandldbd83392006-02-20 09:42:33 +0000510- Bug #854823: socketmodule now builds on Sun platforms even when
511 INET_ADDRSTRLEN is not defined.
512
Georg Brandlf4f44152006-02-18 22:29:33 +0000513- Patch #1393157: os.startfile() now has an optional argument to specify
514 a "command verb" to invoke on the file.
515
Neal Norwitz082b2df2006-02-07 07:04:46 +0000516- Bug #876637, prevent stack corruption when socket descriptor
517 is larger than FD_SETSIZE.
518
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000519- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
520 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
521 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
522
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000523- Patch #1422385: The nis module now supports access to domains other
524 than the system default domain.
525
Martin v. Löwis14694662006-02-03 12:54:16 +0000526- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
527 are reported, the limit on path name lengths is removed, and stat reports
528 WindowsError now (instead of OSError).
529
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000530- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +0000604- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
605 the request code argument, which results in more C-like behaviour
606 for large or negative values.
607
Tim Petersecc6e6a2005-07-10 22:30:55 +0000608- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingerb2594052004-12-05 09:25:51 +0000651- itertools.islice() now accepts None for the start and step arguments.
652 This allows islice() to work more readily with slices:

672 in attribute values.
673
Anthony Baxterc51ee692006-04-01 00:57:31 +0000674- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000675 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000676 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000677 module will not be built.
678
Tim Petersc17976e2006-04-01 00:26:53 +0000679- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
680 aren't officially supported here, and trying to use them will probably
681 raise an exception some day. But dicts have been allowed, and "mostly
682 worked", so support for them won't go away without warning.
683
Georg Brandl338ef7d2006-03-31 18:42:16 +0000684- Bug #1445068: getpass.getpass() can now be given an explicit stream
685 argument to specify where to write the prompt.
686
Georg Brandl22ec80b2006-03-31 18:25:44 +0000687- Patch #1462313, bug #1443328: the pickle modules now can handle classes

693 key to be used for signing the uploaded code.
694
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000695- Queue.Queue objects now support .task_done() and .join() methods
696 to make it easier to monitor when daemon threads have completed
697 processing all enqueued tasks. Patch #1455676.
698
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000699- popen2.Popen objects now preserve the command in a .cmd attribute.

702
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000703- email 4.0 package now integrated. This is largely the same as the email 3.0
704 package that was included in Python 2.3, except that PEP 8 module names are
705 now used (e.g. mail.message instead of email.Message). The MIME classes
706 have been moved to a subpackage (e.g. email.mime.text instead of
707 email.MIMEText). The old names are still supported for now. Several
708 deprecated Message methods have been removed and lots of bugs have been
709 fixed. More details can be found in the email package documentation.
710
Walter Dörwald40108c92006-03-27 08:15:44 +0000711- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
712 (a subclass of tuple) that provides incremental decoders and encoders
713 (a way to use stateful codecs without the stream API). Python functions
714 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
715 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
716 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000717
Walter Dörwald067db482006-03-15 22:17:27 +0000718- Patch #1359365: Calling next() on a closed StringIO.String object raises
719 a ValueError instead of a StopIteration now (like file and cString.String do).
720 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
721 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000722

797 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
798 Ronald L. Rivest offered this advice for Python:
799
800 "The consensus of researchers in this area (at least as
801 expressed at the NIST Hash Function Workshop 10/31/05),
802 is that SHA-256 is a good choice for the time being, but
803 that research should continue, and other alternatives may
804 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000805
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000806- Added a subset of Fredrik Lundh's ElementTree package. Available

Martin v. Löwis56066d22005-08-24 07:38:12 +0000858- Bug #1178484: Return complete lines from codec stream readers
859 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000860 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +0000861

Georg Brandl5dbda752005-07-17 20:27:41 +0000873- Bug #1015140: disambiguated the term "article id" in nntplib docs and
874 docstrings to either "article number" or "message id".
875
Georg Brandla4a8b822005-07-15 09:13:21 +0000876- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
877 parameter, but uses the usual "kwargs=None".
878
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000879- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +0000880 Patch #1209527 (Contributed by Connelly).
881
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000882- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
883 to W3C name (404 -> 'Not Found'). RFE #1216944.
884
Georg Brandl9e43acf2005-07-04 17:16:07 +0000885- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
886 as this can cause problems with apps closing all file descriptors.
887
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000888- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000889 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +0000890

897
Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000898- The tokenize module now detects and reports indentation errors.
899 Bug #1224621.
900
Raymond Hettinger68c04532005-06-10 11:05:19 +0000901- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000902 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000903 the generate_tokens() function now accepts a callable argument that
904 terminates by raising StopIteration.
905
Georg Brandl9166e1a2005-06-04 09:20:03 +0000906- Bug #1196315: fix weakref.WeakValueDictionary constructor.

909 component of the path.
910
Skip Montanaro174dd222005-05-14 20:54:16 +0000911- Patch #1120353: The xmlrpclib module provides better, more transparent,
912 support for datetime.{datetime,date,time} objects. With use_datetime set
913 to True, applications shouldn't have to fiddle with the DateTime wrapper
914 class at all.
915
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000916- distutils.commands.upload was added to support uploading distribution
917 files to PyPI.
918
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000919- distutils.commands.register now encodes the data as UTF-8 before posting
920 them to PyPI.
921
Raymond Hettinger267b8682005-03-27 10:47:39 +0000922- decimal operator and comparison methods now return NotImplemented
923 instead of raising a TypeError when interacting with other types. This
924 allows other classes to implement __radd__ style methods and have them
925 work as expected.
926
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000927- Bug #1163325: Decimal infinities failed to hash. Attempting to
928 hash a NaN raised an InvalidOperation instead of a TypeError.
929

964
Guido van Rossumd0641422005-02-03 15:01:24 +0000965- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
966 disables recursive traversal through instance attributes, which can
967 be exploited in various ways.
968
Tim Peterse3547fd2005-12-16 23:13:57 +0000969- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +0000970 flags on the HTTP listening socket.
971
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +0000972- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
973 Fixed by reading the HTTP body in chunks instead of one big socket.read().
974
Tim Peterse3547fd2005-12-16 23:13:57 +0000975- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +0000976 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
977
Martin v. Löwis1d11de62005-01-29 13:29:23 +0000978- Bug #1110478: Revert os.environ.update to do putenv again.
979
Thomas Hellerd6c6e222005-01-20 19:20:16 +0000980- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
981
Martin v. Löwis22b457e2005-01-16 08:40:58 +0000982- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
983
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000984- Enhancements to the csv module:
985
986 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +0000987 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +0000988 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +0000989 + Dialect parameter parsing has been re-implemented to improve error
990 reporting.
991 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
992 dictates.
993 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000994 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +0000995 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +0000996 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
997 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +0000998 + reader now allows \r characters to be quoted (previously it only allowed
999 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001000 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001001 + Dialect classes passed to the module are no longer instantiated by
1002 the module before being parsed (the former validation scheme required
1003 this, but the mechanism was unreliable).
1004 + The dialect registry now contains instances of the internal
1005 C-coded dialect type, rather than references to python objects.
1006 + the internal c-coded dialect type is now immutable.
1007 + register_dialect now accepts the same keyword dialect specifications
1008 as the reader and writer, allowing the user to register dialects
1009 without first creating a dialect class.
1010 + a configurable limit to the size of parsed fields has been added -
1011 previously, an unmatched quote character could result in the entire
1012 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001013 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001014 the parser field size limit (returning the former limit). The initial
1015 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001016 + A line_num attribute has been added to the reader object, which tracks
1017 the number of lines read from the source iterator. This is not
1018 the same as the number of records returned, as records can span
1019 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001020 + reader and writer objects were not being registered with the cyclic-GC.
1021 This has been fixed.
1022
Brett Cannone6539c42005-01-08 02:43:53 +00001023- _DummyThread objects in the threading module now delete self.__block that is
1024 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1025 lock primitives tend to be limited in number and thus should not be wasted on
1026 a _DummyThread object. Fixes bug #1089632.
1027
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001028- The imghdr module now detects Exif files.
1029
Raymond Hettinger6065d322004-12-20 23:51:53 +00001030- StringIO.truncate() now correctly adjusts the size attribute.
1031 (Bug #951915).
1032
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001033- locale.py now uses an updated locale alias table (built using
1034 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1035 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001036 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001037
Raymond Hettinger3557f422004-12-07 12:02:02 +00001038- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1039
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001040- the pickle module no longer accepts the deprecated None option in the
1041 args tuple returned by __reduce__().
1042
Brett Cannon84667c02004-12-07 03:25:18 +00001043- optparse now optionally imports gettext. This allows its use in setup.py.
1044
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001045- the pickle module no longer uses the deprecated bin parameter.
1046
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001047- the shelve module no longer uses the deprecated binary parameter.
1048
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001049- the pstats module no longer uses the deprecated ignore() method.
1050
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001051- the filecmp module no longer uses the deprecated use_statcache argument.
1052
Raymond Hettinger664347b2004-12-04 21:21:53 +00001053- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1054 extended or overridden by subclasses. Formerly, the subclassed method would
1055 be ignored by the rest of the module. (Bug #1078905).
1056
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001057- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001058 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001059
Walter Dörwald36733692004-12-22 12:50:50 +00001060- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1061 once when a size argument is given. This prevents a buffer overflow in the
1062 tokenizer with very long source lines.
1063
Barry Warsaw538561e2006-01-01 21:48:54 +00001064- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1065 immediately after creating the object, without any intervening
1066 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001067
Skip Montanaro05885812005-01-16 20:48:27 +00001068- The reconvert.quote function can now emit triple-quoted strings. The
1069 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001070
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001071- ``UserString.MutableString`` now supports negative indices in
1072 ``__setitem__`` and ``__delitem__``
1073
Greg Ward40407942005-03-05 02:53:17 +00001074- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1075 correctly.
1076
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001077- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1078 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1079 character even if the user has passed a size parameter to get a proper
1080 line ending. Remove the special handling of a "\r\n" that has been split
1081 between two lines.
1082
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001083- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1084 about illegal code points. The codec now supports PEP 293 style error
1085 handlers.
1086
Walter Dörwald78a78b02005-09-01 12:04:29 +00001087- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001088 from the input stream, so that the output is a byte string in the correct
1089 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001090
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001091- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1092 considering it exactly like a '*'.
1093
Walter Dörwald007f8df2005-10-09 19:42:27 +00001094- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1095 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001096
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001097- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1098
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001099- Patch #1413711: Certain patterns of differences were making difflib
1100 touch the recursion limit.
1101
Walter Dörwald58917a62006-03-31 15:26:22 +00001102- Bug #947906: An object oriented interface has been added to the calendar
1103 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001104 called as a script (e.g. via ``python -mcalendar``). Localized month and
1105 weekday names can be ouput (even if an exotic encoding is used) using
1106 special classes that use unicode.

Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001120- Patch #881820: look for openpty and forkpty also in libbsd.
1121
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001122- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1123 The zlib module is now builtin on Windows.
1124
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001125- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1126
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001127- Bug #1189330: configure did not correctly determine the necessary
1128 value of LINKCC if python was built with GCC 4.0.
1129
Trent Mick8321b422005-07-26 02:29:21 +00001130- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1131 vulnerability in zlib 1.2.1 and 1.2.2.
1132
Brett Cannon08cd5982005-04-24 22:26:38 +00001133- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1134 flags that change binary compatibility. Changes were also made to
1135 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001136 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001137
Bob Ippolitoed233462005-03-29 13:47:59 +00001138- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1139 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1140 no longer exists). This configure patch makes things right.
1141
Martin v. Löwise2713be2005-03-08 15:03:08 +00001142- Bug #1158607: Build with --disable-unicode again.
1143
Brett Cannon46d96232005-02-16 00:07:19 +00001144- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1145 defined. Discovered as a result of not being able to build on OS X.
1146
Brett Cannon516592f2004-12-07 00:42:59 +00001147- setup.py now uses the directories specified in LDFLAGS using the -L option
1148 and in CPPFLAGS using the -I option for adding library and include
1149 directories, respectively, for compiling extension modules against. This has
1150 led to the core being compiled using the values in CPPFLAGS. It also removes
1151 the need for the special-casing of both DarwinPorts and Fink for darwin since
1152 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1153 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1154 Fink, ``-I/opt/local/include`` for DarwinPorts).
1155
Brett Cannon43802422005-02-10 20:48:03 +00001156- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1157 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1158 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1159 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001161C API
1162-----
1163
Tim Petersc9d78aa2006-03-26 23:27:58 +00001164- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1165 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1166 is obtained via the ``PyObject_`` family, it must be released via the
1167 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1168 always been officially true, but when Python's small-object allocator was
1169 introduced, an attempt was made to cater to a few extension modules
1170 discovered at the time that obtained memory via ``PyObject_New`` but
1171 released it via ``PyMem_DEL``. It's years later, and if such code still
1172 exists it will fail now (probably with segfaults, but calling wrong
1173 low-level memory management functions can yield many symptoms).
1174
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001175- Added a C API for set and frozenset objects.
1176

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001179- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1180 mapping argument now. This string is used as a mapping table. Byte values
1181 greater than the length of the string and 0xFFFE are treated as undefined
1182 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001190- Patch #1276356: New resource "urlfetch" is implemented. This enables
1191 even impatient people to run tests that require remote files.
