Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Tim Petersb713ec22006-05-23 18:45:30 +000015- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
16 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
17 an integer close to ``sys.maxint``. This was repaired by patch
18 #1335972, which also gives a nice speedup.
19
Richard Jonescebbefc2006-05-23 18:28:17 +000020- Patch #1337051: reduced size of frame objects.
21
22- PyErr_NewException now accepts a tuple of base classes as its
23 "base" parameter.
24
Georg Brandl658d5132006-05-23 11:17:21 +000025- PyErr_NewException now accepts a tuple of base classes as its
26 "base" parameter.
27
Richard Jones7c88dcc2006-05-23 10:37:38 +000028- Patch #876206: function call speedup by retaining allocated frame
29 objects.
30
Georg Brandl7b90e162006-05-18 07:01:27 +000031- Bug #1462152: file() now checks more thoroughly for invalid mode
32 strings and removes a possible "U" before passing the mode to the
33 C library function.
34
Neal Norwitz1004a532006-05-15 07:17:23 +000035- Patch #1488312, Fix memory alignment problem on SPARC in unicode
36
Neal Norwitz373f0a72006-05-15 07:04:36 +000037- Bug #1487966: Fix SystemError with conditional expression in assignment
38
Martin v. Löwis879768d2006-05-11 13:28:43 +000039- WindowsError now has two error code attributes: errno, which carries
40 the error values from errno.h, and winerror, which carries the error
41 values from winerror.h. Previous versions put the winerror.h values
42 (from GetLastError()) into the errno attribute.
43
Martin v. Löwis77736712006-05-04 05:51:03 +000044- Patch #1475845: Raise IndentationError for unexpected indent.
45
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000046- Patch #1479181: split open() and file() from being aliases for each other.
47
Neal Norwitz7a5fc282006-05-15 06:48:14 +000048Extension Modules
49-----------------
50
Georg Brandl378d5922006-05-17 14:26:50 +000051- Patch #1490224: time.altzone is now set correctly on Cygwin.
52
Georg Brandl8d3342b2006-05-16 07:38:27 +000053- Patch #1435422: zlib's compress and decompress objects now have a
54 copy() method.
55
Neal Norwitz7a5fc282006-05-15 06:48:14 +000056- On Win32, os.listdir now supports arbitrarily-long Unicode path names
57 (up to the system limit of 32K characters).
58
59- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
60 As a result, these functions now raise WindowsError instead of OSError.
61
62- Calling Tk_Init twice is refused if the first call failed as that
63 may deadlock.
64
65Library
66-------
67
Bob Ippolito7298f272006-05-23 18:43:47 +000068- Patch #1281707: speed up gzip.readline.

76
Georg Brandl49c8f4c2006-05-15 19:30:35 +000077- Patch #1488881: add support for external file objects in bz2 compressed
78 tarfiles.
79
Neal Norwitz7a5fc282006-05-15 06:48:14 +000080- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
81 stdout arguments, making it possible to redirect input and output
82 for remote debugging.
83
84- Patch #1484695: Update the tarfile module to version 0.8. This fixes
85 a couple of issues, notably handling of long file names using the
86 GNU LONGNAME extension.
87
88- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
89 new flag when ``name`` is already the name of an option flag.
90
91- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
92 package.
93
94- Patch #1472854: make the rlcompleter.Completer class usable on non-
95 UNIX platforms.
96

120What's New in Python 2.5 alpha 2?
121=================================
122
123*Release date: 27-APR-2006*
124
125Core and builtins
126-----------------
127
Thomas Heller1b046642006-04-18 18:51:06 +0000128- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
129 by converting these apis from macros into exported functions again:
130
131 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
132 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
133 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
134 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
135 PyRun_String Py_CompileString
136
Martin v. Löwis45294a92006-04-18 06:24:08 +0000137- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
138
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000139- All uses of PyStructSequence_InitType have been changed to initialize
140 the type objects only once, even if the interpreter is initialized
141 multiple times.
142
Neal Norwitz61546162006-04-14 05:20:28 +0000143- Bug #1454485, array.array('u') could crash the interpreter. This was
144 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
145 to unicode when it didn't make sense. 'u#' now requires a unicode string.
146
147- Py_UNICODE is unsigned. It was always documented as unsigned, but
148 due to a bug had a signed value in previous versions.
149
Tim Peters3a5e8b12006-04-11 01:44:07 +0000150- Patch #837242: ``id()`` of any Python object always gives a positive
151 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
152 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000153 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000154 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000155
Tim Peters3a5e8b12006-04-11 01:44:07 +0000156 def __hash__(self):
157 return id(self) # WRONG
158
159 because a hash result must be a (short) Python int but it was always
160 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000161 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000162 was always usable as a hash value before this patch. That's no longer
163 necessarily so.
164
165- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000166 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000167 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000168 #1454844)
169
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000170- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
171 involving generators that have paused outside of any ``try`` or ``with``
172 blocks. (In 2.5a1, a paused generator that was part of a reference
173 cycle could not be garbage collected, regardless of whether it was
174 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +0000175
Anthony Baxter51bcb682006-04-05 14:51:42 +0000176Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000179- Patch #1191065: Fix preprocessor problems on systems where recvfrom
180 is a macro.
181
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000182- Bug #1467952: os.listdir() now correctly raises an error if readdir()
183 fails with an error condition.
184
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000185- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
186
187- Bug #1117761: bsddb.*open() no longer raises an exception when using
188 the cachesize parameter.
189
190- Bug #1149413: bsddb.*open() no longer raises an exception when using
191 a temporary db (file=None) with the 'n' flag to truncate on open.
192
193- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
194 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000195
Armin Rigoa9017c32006-04-19 11:50:27 +0000196- Patch #1062014: AF_UNIX sockets under Linux have a special
197 abstract namespace that is now fully supported.
198
Anthony Baxter51bcb682006-04-05 14:51:42 +0000199Library
200-------
201
Tim Peters711bf302006-04-25 03:31:36 +0000202- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
203 a doctest to be skipped (the code is not run, and the expected output
204 or exception is ignored).
205
Nick Coghlanda2268f2006-04-24 04:37:15 +0000206- Fixed contextlib.nested to cope with exceptions being raised and
207 caught inside exit handlers.
208
Greg Wardab05edc2006-04-23 03:47:58 +0000209- Updated optparse module to Optik 1.5.1 (allow numeric constants in
210 hex, octal, or binary; add ``append_const`` action; keep going if
211 gettext cannot be imported; added ``OptionParser.destroy()`` method;
212 added ``epilog`` for better help generation).
213
Tim Peters21fbd572006-04-21 21:18:10 +0000214- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
215 called from a thread spawned as a side effect of importing a module.
216
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000217- The pydoc module now supports documenting packages contained in
218 .zip or .egg files.
219
220- The pkgutil module now has several new utility functions, such
221 as ``walk_packages()`` to support working with packages that are either
222 in the filesystem or zip files.
223
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000224- The mailbox module can now modify and delete messages from
225 mailboxes, in addition to simply reading them. Thanks to Gregory
226 K. Johnson for writing the code, and to the 2005 Google Summer of
227 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000228
Tim Petersc7605f22006-04-17 21:12:33 +0000229- The ``__del__`` method of class ``local`` in module ``_threading_local``
230 returned before accomplishing any of its intended cleanup.

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000236- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
237
Anthony Baxtere29002c2006-04-12 12:07:31 +0000238- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
239 Windows. Bug #1469163.
240
Phillip J. Eby47032112006-04-11 01:07:43 +0000241- The warnings, linecache, inspect, traceback, site, and doctest modules
242 were updated to work correctly with modules imported from zipfiles or
243 via other PEP 302 __loader__ objects.
244
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000245- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000265- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
266 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000267 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000268 CXX from --with-cxx-main, see description in README.
269
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000270- Patch #1429775: Link extension modules with the shared libpython.
271

285
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000286- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
287 it separately and by hand. It also wasn't cleaning up its changes to
288 the current Decimal context.
289
Thomas Woutersabd08882006-04-26 15:53:30 +0000290- regrtest.py now has a -M option to run tests that test the new limits of
291 containers, on 64-bit architectures. Running these tests is only sensible
292 on 64-bit machines with more than two gigabytes of memory. The argument
293 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000314What's New in Python 2.5 alpha 1?
315=================================

Anthony Baxterebed3f62006-04-03 15:03:44 +0000317*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000318
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000319Core and builtins
320-----------------
321
Nick Coghlan43832302006-04-23 17:04:07 +0000322- PEP 338: -m command line switch now delegates to runpy.run_module
323 allowing it to support modules in packages and zipfiles
324
Martin v. Löwisc661b882006-04-20 04:54:23 +0000325- On Windows, .DLL is not an accepted file name extension for
326 extension modules anymore; extensions are only found if they
327 end in .PYD.
328
Martin v. Löwisea62d252006-04-03 10:56:49 +0000329- Bug #1421664: sys.stderr.encoding is now set to the same value as
330 sys.stdout.encoding.
331
Neal Norwitz92e212f2006-04-03 04:48:37 +0000332- __import__ accepts keyword arguments.

Hye-Shik Changd478f342006-03-23 12:32:36 +0000338- Patch #1396919: The system scope threads are reenabled on FreeBSD
339 5.4 and later versions.
340
Neal Norwitze98ccf62006-03-23 05:39:47 +0000341- Bug #1115379: Compiling a Unicode string with an encoding declaration
342 now gives a SyntaxError.
343
Georg Brandlabd1ff82006-03-18 07:59:59 +0000344- Previously, Python code had no easy way to access the contents of a
345 cell object. Now, a ``cell_contents`` attribute has been added
346 (closes patch #1170323).
347
Tim Peterscf79aac2006-03-16 01:14:46 +0000348- Patch #1123430: Python's small-object allocator now returns an arena to
349 the system ``free()`` when all memory within an arena becomes unused
350 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
351 freed. Some applications will see a drop in virtual memory size now,
352 especially long-running applications that, from time to time, temporarily
353 use a large number of small objects. Note that when Python returns an
354 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000355 platform C library will in turn return that memory to the operating system.
356 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000357 appears to be effective at least on Microsoft C and gcc-based systems.
358 Thanks to Evan Jones for hard work and patience.
359
Georg Brandl533ff6f2006-03-08 18:09:27 +0000360- Patch #1434038: property() now uses the getter's docstring if there is
361 no "doc" argument given. This makes it possible to legitimately use
362 property() as a decorator to produce a read-only property.
363
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000364- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
365 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
366 of requiring an int or long in slicing and a few other contexts, enabling
367 other objects (e.g. Numeric Python's integers) to be used as slice indices.
368
Neal Norwitz995acdf2006-03-07 05:01:00 +0000369- Fixed various bugs reported by Coverity's Prevent tool.
370
Brett Cannonbf364092006-03-01 04:25:17 +0000371- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
372 new exception base class, BaseException, which has a new message attribute.
373 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
374 Raising a string exception now raises a DeprecationWarning.
375
Thomas Woutersfb609f42006-02-28 16:37:25 +0000376- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
377 explicitly relative, using 'from .module import name' to mean 'from the same
378 package as this module is in. Imports without dots still default to the
379 old relative-then-absolute, unless 'from __future__ import
380 absolute_import' is used.
381
Brett Cannona7446e32006-02-27 23:39:10 +0000382- Properly check if 'warnings' raises an exception (usually when a filter set
383 to "error" is triggered) when raising a warning for raising string
384 exceptions.
385
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000386- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000387 The name was removed from Include/code.h.
388
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000389- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000390
Guido van Rossum1968ad32006-02-25 22:38:04 +0000391- Patch 1433928:
392 - The copy module now "copies" function objects (as atomic objects).
393 - dict.__getitem__ now looks for a __missing__ hook before raising
394 KeyError.
395
Tim Peters84ef21c2006-02-28 20:39:06 +0000396- PEP 343: with statement implemented. Needs ``from __future__ import
397 with_statement``. Use of 'with' as a variable will generate a warning.
398 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000399 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000400 The following objects have __context__ methods:
401 - The built-in file type.
402 - The thread.LockType type.
403 - The following types defined by the threading module:
404 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
405 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000406
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000407- Fix the encodings package codec search function to only search
408 inside its own package. Fixes problem reported in patch #1433198.
409
410 Note: Codec packages should implement and register their own
411 codec search function. PEP 100 has the details.
412
Martin v. Löwis18e16552006-02-15 17:27:45 +0000413- PEP 353: Using ssize_t as the index type.
414
Neal Norwitzfc76d632006-01-10 06:03:13 +0000415- Patch #1400181, fix unicode string formatting to not use the locale.
416 This is how string objects work. u'%f' could use , instead of .
417 for the decimal point. Now both strings and unicode always use periods.
418
Neal Norwitz671b9e32006-01-09 07:07:12 +0000419- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
420 configure would break checking curses.h.
421
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000422- Bug #959576: The pwd module is now builtin. This allows Python to be
423 built on UNIX platforms without $HOME set.
424
Neal Norwitzc10978f2005-12-19 06:07:16 +0000425- Bug #1072182, fix some potential problems if characters are signed.
426
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000427- Bug #889500, fix line number on SyntaxWarning for global declarations.
428
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000429- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
430
Neal Norwitze7214a12005-12-18 05:03:17 +0000431- Support for converting hex strings to floats no longer works.
432 This was not portable. float('0x3') now raises a ValueError.
433
Barry Warsaw2a38a862005-12-18 01:27:35 +0000434- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000435 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000436 is now displayed in interactive prompt banner.
437
Georg Brandlfa166682005-12-17 21:45:17 +0000438- Implementation of PEP 341 - Unification of try/except and try/finally.
439 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000440 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000441
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000442- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
443 now encodes backslash correctly.
444
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000445- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
446
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000447- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000448 and long longs.
449
Neal Norwitz67715f02005-11-09 06:59:35 +0000450- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000451 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000452 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000453
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000454- Replaced most Unicode charmap codecs with new ones using the
455 new Unicode translate string feature in the builtin charmap
456 codec; the codecs were created from the mapping tables available
457 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
458 encodings now include a mapping for the Apple logo)
459
Tim Peterse3547fd2005-12-16 23:13:57 +0000460- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000461
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000462- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000463
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000464- A new AST parser implementation was completed. The abstract
465 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000466 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000467
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000468- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000469 The following code now raises a SyntaxError: foo(a = i for i in range(10))
470
Neal Norwitz708e51a2005-10-03 04:48:15 +0000471- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
472
Neal Norwitz11bd1192005-10-03 00:54:56 +0000473- SF Bug #887946: fix segfault when redirecting stdin from a directory.
474 Provide a warning when a directory is passed on the command line.
475
Neal Norwitz40d37812005-10-02 01:48:49 +0000476- Fix segfault with invalid coding.
477
478- SF bug #772896: unknown encoding results in MemoryError.
479
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000480- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000481 supported a __len__() method which evaluated to False when the iterator
482 was empty.
483
Guido van Rossum630db602005-09-20 18:49:54 +0000484- On 64-bit platforms, when __len__() returns a value that cannot be
485 represented as a C int, raise OverflowError.
486
Skip Montanarof8948ca2005-09-19 03:54:46 +0000487- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000488 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000489
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000490- SF bug #893549: parsing keyword arguments was broken with a few format
491 codes.
492
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000493- Changes donated by Elemental Security to make it work on AIX 5.3
494 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
495 bug #105470: test_pwd fails on 64bit system (Opteron).
496
Guido van Rossum539c6622005-09-14 17:49:54 +0000497- Changes donated by Elemental Security to make it work on HP-UX 11 on
498 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
499
Georg Brandl4550b8d2005-08-26 06:43:52 +0000500- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000501 (fixes bug #1119418).
502
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000503- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
504
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000505- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
506 exceptions that cause a function to exit.
507
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000508- The implementation of set() and frozenset() was revised to use its
509 own internal data structure. Memory consumption is reduced by 1/3
510 and there are modest speed-ups as well. The API is unchanged.
511
Tim Petersde7990b2005-07-17 23:45:23 +0000512- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
513
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000514- SF bug #1229429: PyObject_CallMethod failed to decrement some
515 reference counts in some error exit cases.
516
Tim Petersecc6e6a2005-07-10 22:30:55 +0000517- SF bug #1185883: Python's small-object memory allocator took over
518 a block managed by the platform C library whenever a realloc specified
519 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000520 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000521 portable way to copy data from the C-managed block into Python's
522 small-object space without risking a memory fault. Python's small-object
523 realloc now leaves such blocks under the control of the platform C
524 realloc.
525
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000526- SF bug #1232517: An overflow error was not detected properly when
527 attempting to convert a large float to an int in os.utime().
528
Raymond Hettinger3296e692005-06-29 23:29:56 +0000529- SF bug #1224347: hex longs now print with lowercase letters just
530 like their int counterparts.
531
Michael W. Hudson188d4362005-06-20 16:52:57 +0000532- SF bug #1163563: the original fix for bug #1010677 ("thread Module
533 Breaks PyGILState_Ensure()") broke badly in the case of multiple
534 interpreter states; back out that fix and do a better job (see
535 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
536 for a longer write-up of the problem).
537
Michael W. Hudsondf888462005-06-03 14:41:55 +0000538- SF patch #1180995: marshal now uses a binary format by default when
539 serializing floats.
540
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000541- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
542 the routines that promise to produce IEEE 754 binary representations
543 of floats now simply copy bytes around.
544
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000545- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
546 278.
547
Brett Cannonc3647ac2005-04-26 03:45:26 +0000548- patch #1109424: int, long, float, complex, and unicode now check for the
549 proper magic slot for type conversions when subclassed. Previously the
550 magic slot was ignored during conversion. Semantics now match the way
551 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000552 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000553 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000554 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000555
Barry Warsawc8d907c2005-04-19 23:43:40 +0000556- Descriptors defined in C with a PyGetSetDef structure, where the setter is
557 NULL, now raise an AttributeError when attempting to set or delete the
558 attribute. Previously a TypeError was raised, but this was inconsistent
559 with the equivalent pure-Python implementation.
560
Michael W. Hudson774479c2005-04-18 08:46:17 +0000561- It is now safe to call PyGILState_Release() before
562 PyEval_InitThreads() (note that if there is reason to believe there
563 are multiple threads around you still must call PyEval_InitThreads()
564 before using the Python API; this fix is for extension modules that
565 have no way of knowing if Python is multi-threaded yet).
566
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000567- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
568 disabled caused a crash.
569
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000570- Bug #1165306: instancemethod_new allowed the creation of a method
571 with im_class == im_self == NULL, which caused a crash when called.
572
Tim Petersecc6e6a2005-07-10 22:30:55 +0000573- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000574 fixes the crash seen in bug #1165761
575
Raymond Hettinger96229b12005-03-11 06:49:40 +0000576- Added two new builtins, any() and all().
577
Brett Cannon409d8f22005-03-05 06:47:57 +0000578- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000579 (e.g., ``class C(): pass`` is no longer a syntax error).
580 Patch #1176012 added support to the 'parser' module and 'compiler' package
581 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000582
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000583- Patch #1115086: Support PY_LONGLONG in structmember.
584
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000585- Bug #1155938: new style classes did not check that __init__() was
586 returning None.
587
Tim Petersecc6e6a2005-07-10 22:30:55 +0000588- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000589 ('\') with a specific error message.
590
Martin v. Löwisff232d72005-03-03 09:24:38 +0000591- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
592
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000593- Bug #1124295: the __name__ attribute of file objects was
594 inadvertently made inaccessible in restricted mode.
595
Tim Petersecc6e6a2005-07-10 22:30:55 +0000596- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000597 an ferror() call.
598
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000599- min() and max() now support key= arguments with the same meaning as in
600 list.sort().
601
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000602- The peephole optimizer now performs simple constant folding in expressions:
603 (2+3) --> (5).
604
Raymond Hettingera422c342005-01-11 03:03:27 +0000605- set and frozenset objects can now be marshalled. SF #1098985.
606
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000607- Bug #1077106: Poor argument checking could cause memory corruption
608 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000609
Jeremy Hyltonab630502005-02-04 18:44:06 +0000610- The parser did not complain about future statements in illegal
611 positions. It once again reports a syntax error if a future
612 statement occurs after anything other than a doc string.
613
Neil Schemenauercf52c072005-08-12 17:34:58 +0000614- Change the %s format specifier for str objects so that it returns a
615 unicode instance if the argument is not an instance of basestring and
616 calling __str__ on the argument returns a unicode instance.
617
Tim Petersf4e69282006-02-27 17:15:31 +0000618- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
619 current thread state when the auto-GIL-state machinery knows about
620 it (since the thread state is being deleted, continuing to remember it
621 can't help, but can hurt if another thread happens to get created with
622 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +0000754- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
755 the request code argument, which results in more C-like behaviour
756 for large or negative values.
757
Tim Petersecc6e6a2005-07-10 22:30:55 +0000758- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlaf410b52005-07-08 22:26:13 +0000760
Georg Brandl6b95f1d2005-06-03 19:47:00 +0000761- Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.

Raymond Hettinger4aec61e2005-03-18 21:20:23 +0000772- collections.deque objects now support a remove() method.
773
Raymond Hettinger984f9bb2005-03-09 16:38:48 +0000774- operator.itemgetter() and operator.attrgetter() now support retrieving

800
Raymond Hettingerb2594052004-12-05 09:25:51 +0000801- itertools.islice() now accepts None for the start and step arguments.
802 This allows islice() to work more readily with slices:
803 islice(s.start, s.stop, s.step)
804
Skip Montanaro0af3ade2005-01-13 04:12:31 +0000805- datetime.datetime() now has a strptime class method which can be used to

810
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000811Library
812-------
813
Nick Coghlan43832302006-04-23 17:04:07 +0000814- PEP 338: new module runpy defines a run_module function to support
815 executing modules which provide access to source code or a code object
816 via the PEP 302 import mechanisms.
817
Anthony Baxter93f5b932006-04-03 08:05:07 +0000818- The email module's parsedate_tz function now sets the daylight savings
819 flag to -1 (unknown) since it can't tell from the date whether it should
820 be set.
821
Fred Drakead5177c2006-04-01 22:14:43 +0000822- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
823 now sport attributes that provide access to the parts of the result.
824

826 in attribute values.
827
Anthony Baxterc51ee692006-04-01 00:57:31 +0000828- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000829 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000830 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000831 module will not be built.
832
Tim Petersc17976e2006-04-01 00:26:53 +0000833- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
834 aren't officially supported here, and trying to use them will probably
835 raise an exception some day. But dicts have been allowed, and "mostly
836 worked", so support for them won't go away without warning.
837
Georg Brandl338ef7d2006-03-31 18:42:16 +0000838- Bug #1445068: getpass.getpass() can now be given an explicit stream
839 argument to specify where to write the prompt.
840
Georg Brandl22ec80b2006-03-31 18:25:44 +0000841- Patch #1462313, bug #1443328: the pickle modules now can handle classes

856
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000857- email 4.0 package now integrated. This is largely the same as the email 3.0
858 package that was included in Python 2.3, except that PEP 8 module names are
859 now used (e.g. mail.message instead of email.Message). The MIME classes
860 have been moved to a subpackage (e.g. email.mime.text instead of
861 email.MIMEText). The old names are still supported for now. Several
862 deprecated Message methods have been removed and lots of bugs have been
863 fixed. More details can be found in the email package documentation.
864
Walter Dörwald40108c92006-03-27 08:15:44 +0000865- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
866 (a subclass of tuple) that provides incremental decoders and encoders
867 (a way to use stateful codecs without the stream API). Python functions
868 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
869 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
870 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000871
Walter Dörwald067db482006-03-15 22:17:27 +0000872- Patch #1359365: Calling next() on a closed StringIO.String object raises
873 a ValueError instead of a StopIteration now (like file and cString.String do).
874 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
875 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000876
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000877- A regrtest option -w was added to re-run failed tests in verbose mode.

880 interpreter to exit.
881
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000882- The function get_count() has been added to the gc module, and gc.collect()
883 grew an optional 'generation' argument.

956 is that SHA-256 is a good choice for the time being, but
957 that research should continue, and other alternatives may
958 arise from this research. The larger SHA's also seem OK."

1146 dictates.
1147 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001148 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001149 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001150 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1151 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001152 + reader now allows \r characters to be quoted (previously it only allowed
1153 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001154 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001155 + Dialect classes passed to the module are no longer instantiated by
1156 the module before being parsed (the former validation scheme required
1157 this, but the mechanism was unreliable).
1158 + The dialect registry now contains instances of the internal
1159 C-coded dialect type, rather than references to python objects.
1160 + the internal c-coded dialect type is now immutable.
1161 + register_dialect now accepts the same keyword dialect specifications
1162 as the reader and writer, allowing the user to register dialects
1163 without first creating a dialect class.
1164 + a configurable limit to the size of parsed fields has been added -
1165 previously, an unmatched quote character could result in the entire
1166 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001167 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001168 the parser field size limit (returning the former limit). The initial
1169 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001170 + A line_num attribute has been added to the reader object, which tracks
1171 the number of lines read from the source iterator. This is not
1172 the same as the number of records returned, as records can span
1173 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001174 + reader and writer objects were not being registered with the cyclic-GC.
1175 This has been fixed.
1176
Brett Cannone6539c42005-01-08 02:43:53 +00001177- _DummyThread objects in the threading module now delete self.__block that is
1178 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1179 lock primitives tend to be limited in number and thus should not be wasted on
1180 a _DummyThread object. Fixes bug #1089632.
1181
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001182- The imghdr module now detects Exif files.
1183
Raymond Hettinger6065d322004-12-20 23:51:53 +00001184- StringIO.truncate() now correctly adjusts the size attribute.
1185 (Bug #951915).
1186
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001187- locale.py now uses an updated locale alias table (built using
1188 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1189 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001190 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001191
Raymond Hettinger3557f422004-12-07 12:02:02 +00001192- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1193
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001194- the pickle module no longer accepts the deprecated None option in the
1195 args tuple returned by __reduce__().
1196
Brett Cannon84667c02004-12-07 03:25:18 +00001197- optparse now optionally imports gettext. This allows its use in setup.py.
1198
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001199- the pickle module no longer uses the deprecated bin parameter.
1200
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001201- the shelve module no longer uses the deprecated binary parameter.
1202
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001203- the pstats module no longer uses the deprecated ignore() method.
1204
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001205- the filecmp module no longer uses the deprecated use_statcache argument.
1206
Raymond Hettinger664347b2004-12-04 21:21:53 +00001207- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1208 extended or overridden by subclasses. Formerly, the subclassed method would
1209 be ignored by the rest of the module. (Bug #1078905).
1210
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001211- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001212 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001213
Walter Dörwald36733692004-12-22 12:50:50 +00001214- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1215 once when a size argument is given. This prevents a buffer overflow in the
1216 tokenizer with very long source lines.
1217
Barry Warsaw538561e2006-01-01 21:48:54 +00001218- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1219 immediately after creating the object, without any intervening
1220 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001221
Skip Montanaro05885812005-01-16 20:48:27 +00001222- The reconvert.quote function can now emit triple-quoted strings. The
1223 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001224
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001225- ``UserString.MutableString`` now supports negative indices in
1226 ``__setitem__`` and ``__delitem__``
1227
Greg Ward40407942005-03-05 02:53:17 +00001228- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1229 correctly.
1230
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001231- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1232 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1233 character even if the user has passed a size parameter to get a proper
1234 line ending. Remove the special handling of a "\r\n" that has been split
1235 between two lines.
1236
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001237- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1238 about illegal code points. The codec now supports PEP 293 style error
1239 handlers.
1240
Walter Dörwald78a78b02005-09-01 12:04:29 +00001241- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001242 from the input stream, so that the output is a byte string in the correct
1243 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001244
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001245- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1246 considering it exactly like a '*'.
1247
Walter Dörwald007f8df2005-10-09 19:42:27 +00001248- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1249 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001250
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001251- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1252
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001253- Patch #1413711: Certain patterns of differences were making difflib
1254 touch the recursion limit.
1255
Walter Dörwald58917a62006-03-31 15:26:22 +00001256- Bug #947906: An object oriented interface has been added to the calendar
1257 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001258 called as a script (e.g. via ``python -mcalendar``). Localized month and
1259 weekday names can be ouput (even if an exotic encoding is used) using
1260 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001261
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001262Build
1263-----
1264
Neal Norwitz602d3392006-03-31 08:21:40 +00001265- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1266 by using -mieee gcc option.
1267
Martin v. Löwis86d66262006-02-17 08:40:11 +00001268- Patch #1432345: Make python compile on DragonFly.
1269
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001270- Build support for Win64-AMD64 was added.
1271
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001272- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1273
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001274- Patch #881820: look for openpty and forkpty also in libbsd.
1275
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001276- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1277 The zlib module is now builtin on Windows.
1278
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001279- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1280
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001281- Bug #1189330: configure did not correctly determine the necessary
1282 value of LINKCC if python was built with GCC 4.0.
1283
Trent Mick8321b422005-07-26 02:29:21 +00001284- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1285 vulnerability in zlib 1.2.1 and 1.2.2.
1286
Brett Cannon08cd5982005-04-24 22:26:38 +00001287- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1288 flags that change binary compatibility. Changes were also made to
1289 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001290 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001291
Bob Ippolitoed233462005-03-29 13:47:59 +00001292- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1293 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1294 no longer exists). This configure patch makes things right.
1295
Martin v. Löwise2713be2005-03-08 15:03:08 +00001296- Bug #1158607: Build with --disable-unicode again.
1297
Brett Cannon46d96232005-02-16 00:07:19 +00001298- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1299 defined. Discovered as a result of not being able to build on OS X.
1300
Brett Cannon516592f2004-12-07 00:42:59 +00001301- setup.py now uses the directories specified in LDFLAGS using the -L option
1302 and in CPPFLAGS using the -I option for adding library and include
1303 directories, respectively, for compiling extension modules against. This has
1304 led to the core being compiled using the values in CPPFLAGS. It also removes
1305 the need for the special-casing of both DarwinPorts and Fink for darwin since
1306 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1307 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1308 Fink, ``-I/opt/local/include`` for DarwinPorts).
1309
Brett Cannon43802422005-02-10 20:48:03 +00001310- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1311 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1312 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1313 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001315C API
1316-----
1317
Tim Petersc9d78aa2006-03-26 23:27:58 +00001318- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1319 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1320 is obtained via the ``PyObject_`` family, it must be released via the
1321 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1322 always been officially true, but when Python's small-object allocator was
1323 introduced, an attempt was made to cater to a few extension modules
1324 discovered at the time that obtained memory via ``PyObject_New`` but
1325 released it via ``PyMem_DEL``. It's years later, and if such code still
1326 exists it will fail now (probably with segfaults, but calling wrong
1327 low-level memory management functions can yield many symptoms).
1328
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001329- Added a C API for set and frozenset objects.
1330
Raymond Hettinger66517482004-12-03 11:45:13 +00001331- Removed PyRange_New().
1332
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001333- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1334 mapping argument now. This string is used as a mapping table. Byte values
1335 greater than the length of the string and 0xFFFE are treated as undefined
1336 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001343
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001344- Patch #1276356: New resource "urlfetch" is implemented. This enables
