Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandl7b90e162006-05-18 07:01:27 +000015- Bug #1462152: file() now checks more thoroughly for invalid mode
16 strings and removes a possible "U" before passing the mode to the
17 C library function.
18
Neal Norwitz1004a532006-05-15 07:17:23 +000019- Patch #1488312, Fix memory alignment problem on SPARC in unicode
20
Neal Norwitz373f0a72006-05-15 07:04:36 +000021- Bug #1487966: Fix SystemError with conditional expression in assignment
22
Martin v. Löwis879768d2006-05-11 13:28:43 +000023- WindowsError now has two error code attributes: errno, which carries
24 the error values from errno.h, and winerror, which carries the error
25 values from winerror.h. Previous versions put the winerror.h values
26 (from GetLastError()) into the errno attribute.
27
Martin v. Löwis77736712006-05-04 05:51:03 +000028- Patch #1475845: Raise IndentationError for unexpected indent.
29
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000030- Patch #1479181: split open() and file() from being aliases for each other.

Neal Norwitz7a5fc282006-05-15 06:48:14 +000032Extension Modules
33-----------------
34
Georg Brandl378d5922006-05-17 14:26:50 +000035- Patch #1490224: time.altzone is now set correctly on Cygwin.
36
Georg Brandl8d3342b2006-05-16 07:38:27 +000037- Patch #1435422: zlib's compress and decompress objects now have a
38 copy() method.
39
Neal Norwitz7a5fc282006-05-15 06:48:14 +000040- On Win32, os.listdir now supports arbitrarily-long Unicode path names
41 (up to the system limit of 32K characters).
42
43- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
44 As a result, these functions now raise WindowsError instead of OSError.
45
46- Calling Tk_Init twice is refused if the first call failed as that
47 may deadlock.
48
49Library
50-------
51
Georg Brandlb89316f2006-05-17 15:51:16 +000052- Patch #1180296: Two new functions were added to the locale module:
53 format_string() to get the effect of "format % items" but locale-aware,
54 and currency() to format a monetary number with currency sign.
55
Georg Brandle3a25832006-05-17 14:56:04 +000056- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
57 and several features added, such as speed and geometry control.

60 tarfiles.
61
Neal Norwitz7a5fc282006-05-15 06:48:14 +000062- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
63 stdout arguments, making it possible to redirect input and output
64 for remote debugging.
65
66- Patch #1484695: Update the tarfile module to version 0.8. This fixes
67 a couple of issues, notably handling of long file names using the
68 GNU LONGNAME extension.
69
70- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
71 new flag when ``name`` is already the name of an option flag.
72
73- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
74 package.
75
76- Patch #1472854: make the rlcompleter.Completer class usable on non-
77 UNIX platforms.
78

102What's New in Python 2.5 alpha 2?
103=================================
104
105*Release date: 27-APR-2006*
106
107Core and builtins
108-----------------
109
Thomas Heller1b046642006-04-18 18:51:06 +0000110- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
111 by converting these apis from macros into exported functions again:
112
113 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
114 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
115 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
116 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
117 PyRun_String Py_CompileString
118
Martin v. Löwis45294a92006-04-18 06:24:08 +0000119- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
120
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000121- All uses of PyStructSequence_InitType have been changed to initialize
122 the type objects only once, even if the interpreter is initialized
123 multiple times.
124
Neal Norwitz61546162006-04-14 05:20:28 +0000125- Bug #1454485, array.array('u') could crash the interpreter. This was
126 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
127 to unicode when it didn't make sense. 'u#' now requires a unicode string.
128
129- Py_UNICODE is unsigned. It was always documented as unsigned, but
130 due to a bug had a signed value in previous versions.
131
Tim Peters3a5e8b12006-04-11 01:44:07 +0000132- Patch #837242: ``id()`` of any Python object always gives a positive
133 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
134 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000135 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000136 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000137
Tim Peters3a5e8b12006-04-11 01:44:07 +0000138 def __hash__(self):
139 return id(self) # WRONG
140
141 because a hash result must be a (short) Python int but it was always
142 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000143 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000144 was always usable as a hash value before this patch. That's no longer
145 necessarily so.
146
147- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000148 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000149 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000150 #1454844)
151
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000152- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
153 involving generators that have paused outside of any ``try`` or ``with``
154 blocks. (In 2.5a1, a paused generator that was part of a reference
155 cycle could not be garbage collected, regardless of whether it was
156 paused in a ``try`` or ``with`` block.)

160
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000161- Patch #1191065: Fix preprocessor problems on systems where recvfrom
162 is a macro.
163
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000164- Bug #1467952: os.listdir() now correctly raises an error if readdir()
165 fails with an error condition.
166
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000167- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
168
169- Bug #1117761: bsddb.*open() no longer raises an exception when using
170 the cachesize parameter.
171
172- Bug #1149413: bsddb.*open() no longer raises an exception when using
173 a temporary db (file=None) with the 'n' flag to truncate on open.
174
175- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
176 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000177
Armin Rigoa9017c32006-04-19 11:50:27 +0000178- Patch #1062014: AF_UNIX sockets under Linux have a special
179 abstract namespace that is now fully supported.
180
Anthony Baxter51bcb682006-04-05 14:51:42 +0000181Library
182-------
183
Tim Peters711bf302006-04-25 03:31:36 +0000184- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
185 a doctest to be skipped (the code is not run, and the expected output
186 or exception is ignored).
187
Nick Coghlanda2268f2006-04-24 04:37:15 +0000188- Fixed contextlib.nested to cope with exceptions being raised and
189 caught inside exit handlers.
190
Greg Wardab05edc2006-04-23 03:47:58 +0000191- Updated optparse module to Optik 1.5.1 (allow numeric constants in
192 hex, octal, or binary; add ``append_const`` action; keep going if
193 gettext cannot be imported; added ``OptionParser.destroy()`` method;
194 added ``epilog`` for better help generation).
195
Tim Peters21fbd572006-04-21 21:18:10 +0000196- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
197 called from a thread spawned as a side effect of importing a module.
198
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000199- The pydoc module now supports documenting packages contained in
200 .zip or .egg files.
201
202- The pkgutil module now has several new utility functions, such
203 as ``walk_packages()`` to support working with packages that are either
204 in the filesystem or zip files.
205
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000206- The mailbox module can now modify and delete messages from
207 mailboxes, in addition to simply reading them. Thanks to Gregory
208 K. Johnson for writing the code, and to the 2005 Google Summer of
209 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000210
Tim Petersc7605f22006-04-17 21:12:33 +0000211- The ``__del__`` method of class ``local`` in module ``_threading_local``
212 returned before accomplishing any of its intended cleanup.

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000218- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
219
Anthony Baxtere29002c2006-04-12 12:07:31 +0000220- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
221 Windows. Bug #1469163.
222
Phillip J. Eby47032112006-04-11 01:07:43 +0000223- The warnings, linecache, inspect, traceback, site, and doctest modules
224 were updated to work correctly with modules imported from zipfiles or
225 via other PEP 302 __loader__ objects.
226
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000227- Patch #1467770: Reduce usage of subprocess._active to processes which
228 the application hasn't waited on.

238-----
239
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000240- The Makefile now has a reindent target, which runs reindent.py on
241 the library.
242

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000247- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
248 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000249 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000250 CXX from --with-cxx-main, see description in README.
251
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000252- Patch #1429775: Link extension modules with the shared libpython.
253
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000254- Fixed a libffi build problem on MIPS systems.
255
Tim Peters8931ff12006-05-13 23:28:20 +0000256- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
257 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

262
Nick Coghlanda2268f2006-04-24 04:37:15 +0000263- test_contextlib now checks contextlib.nested can cope with exceptions
264 being raised and caught inside exit handlers.

Nick Coghlan27ec1a72006-04-24 04:32:47 +0000266- test_cmd_line now checks operation of the -m and -c command switches
267
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000268- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
269 it separately and by hand. It also wasn't cleaning up its changes to
270 the current Decimal context.
271
Thomas Woutersabd08882006-04-26 15:53:30 +0000272- regrtest.py now has a -M option to run tests that test the new limits of
273 containers, on 64-bit architectures. Running these tests is only sensible
274 on 64-bit machines with more than two gigabytes of memory. The argument
275 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000296What's New in Python 2.5 alpha 1?
297=================================
298
Anthony Baxterebed3f62006-04-03 15:03:44 +0000299*Release date: 05-APR-2006*

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000301Core and builtins
302-----------------
303
Nick Coghlan43832302006-04-23 17:04:07 +0000304- PEP 338: -m command line switch now delegates to runpy.run_module
305 allowing it to support modules in packages and zipfiles
306
Martin v. Löwisc661b882006-04-20 04:54:23 +0000307- On Windows, .DLL is not an accepted file name extension for
308 extension modules anymore; extensions are only found if they
309 end in .PYD.
310
Martin v. Löwisea62d252006-04-03 10:56:49 +0000311- Bug #1421664: sys.stderr.encoding is now set to the same value as
312 sys.stdout.encoding.
313
Neal Norwitz92e212f2006-04-03 04:48:37 +0000314- __import__ accepts keyword arguments.
315
Georg Brandlccadf842006-03-31 18:54:53 +0000316- Patch #1460496: round() now accepts keyword arguments.
317
Anthony Baxter262c00a2006-03-30 10:53:17 +0000318- Fixed bug #1459029 - unicode reprs were double-escaped.
319
Hye-Shik Changd478f342006-03-23 12:32:36 +0000320- Patch #1396919: The system scope threads are reenabled on FreeBSD
321 5.4 and later versions.
322
Neal Norwitze98ccf62006-03-23 05:39:47 +0000323- Bug #1115379: Compiling a Unicode string with an encoding declaration
324 now gives a SyntaxError.
325
Georg Brandlabd1ff82006-03-18 07:59:59 +0000326- Previously, Python code had no easy way to access the contents of a
327 cell object. Now, a ``cell_contents`` attribute has been added
328 (closes patch #1170323).
329
Tim Peterscf79aac2006-03-16 01:14:46 +0000330- Patch #1123430: Python's small-object allocator now returns an arena to
331 the system ``free()`` when all memory within an arena becomes unused
332 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
333 freed. Some applications will see a drop in virtual memory size now,
334 especially long-running applications that, from time to time, temporarily
335 use a large number of small objects. Note that when Python returns an
336 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000337 platform C library will in turn return that memory to the operating system.
338 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000339 appears to be effective at least on Microsoft C and gcc-based systems.
340 Thanks to Evan Jones for hard work and patience.
341
Georg Brandl533ff6f2006-03-08 18:09:27 +0000342- Patch #1434038: property() now uses the getter's docstring if there is
343 no "doc" argument given. This makes it possible to legitimately use
344 property() as a decorator to produce a read-only property.
345
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000346- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
347 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
348 of requiring an int or long in slicing and a few other contexts, enabling
349 other objects (e.g. Numeric Python's integers) to be used as slice indices.
350
Neal Norwitz995acdf2006-03-07 05:01:00 +0000351- Fixed various bugs reported by Coverity's Prevent tool.
352
Brett Cannonbf364092006-03-01 04:25:17 +0000353- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
354 new exception base class, BaseException, which has a new message attribute.
355 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
356 Raising a string exception now raises a DeprecationWarning.
357
Thomas Woutersfb609f42006-02-28 16:37:25 +0000358- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
359 explicitly relative, using 'from .module import name' to mean 'from the same
360 package as this module is in. Imports without dots still default to the
361 old relative-then-absolute, unless 'from __future__ import
362 absolute_import' is used.
363
Brett Cannona7446e32006-02-27 23:39:10 +0000364- Properly check if 'warnings' raises an exception (usually when a filter set
365 to "error" is triggered) when raising a warning for raising string
366 exceptions.
367
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000368- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000369 The name was removed from Include/code.h.
370
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000371- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000372
Guido van Rossum1968ad32006-02-25 22:38:04 +0000373- Patch 1433928:
374 - The copy module now "copies" function objects (as atomic objects).
375 - dict.__getitem__ now looks for a __missing__ hook before raising
376 KeyError.
377
Tim Peters84ef21c2006-02-28 20:39:06 +0000378- PEP 343: with statement implemented. Needs ``from __future__ import
379 with_statement``. Use of 'with' as a variable will generate a warning.
380 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000381 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000382 The following objects have __context__ methods:
383 - The built-in file type.
384 - The thread.LockType type.
385 - The following types defined by the threading module:
386 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
387 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000388
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000389- Fix the encodings package codec search function to only search
390 inside its own package. Fixes problem reported in patch #1433198.
391
392 Note: Codec packages should implement and register their own
393 codec search function. PEP 100 has the details.
394
Martin v. Löwis18e16552006-02-15 17:27:45 +0000395- PEP 353: Using ssize_t as the index type.
396
Neal Norwitzfc76d632006-01-10 06:03:13 +0000397- Patch #1400181, fix unicode string formatting to not use the locale.
398 This is how string objects work. u'%f' could use , instead of .
399 for the decimal point. Now both strings and unicode always use periods.
400
Neal Norwitz671b9e32006-01-09 07:07:12 +0000401- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
402 configure would break checking curses.h.
403
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000404- Bug #959576: The pwd module is now builtin. This allows Python to be
405 built on UNIX platforms without $HOME set.
406
Neal Norwitzc10978f2005-12-19 06:07:16 +0000407- Bug #1072182, fix some potential problems if characters are signed.
408
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000409- Bug #889500, fix line number on SyntaxWarning for global declarations.
410
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000411- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
412
Neal Norwitze7214a12005-12-18 05:03:17 +0000413- Support for converting hex strings to floats no longer works.
414 This was not portable. float('0x3') now raises a ValueError.
415
Barry Warsaw2a38a862005-12-18 01:27:35 +0000416- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000417 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000418 is now displayed in interactive prompt banner.
419
Georg Brandlfa166682005-12-17 21:45:17 +0000420- Implementation of PEP 341 - Unification of try/except and try/finally.
421 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000422 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000423
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000424- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
425 now encodes backslash correctly.
426
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000427- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000429- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000430 and long longs.
431
Neal Norwitz67715f02005-11-09 06:59:35 +0000432- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000433 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000434 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000435
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000436- Replaced most Unicode charmap codecs with new ones using the
437 new Unicode translate string feature in the builtin charmap
438 codec; the codecs were created from the mapping tables available
439 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
440 encodings now include a mapping for the Apple logo)
441
Tim Peterse3547fd2005-12-16 23:13:57 +0000442- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000443
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000444- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000445
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000446- A new AST parser implementation was completed. The abstract
447 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000448 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000449
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000450- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000451 The following code now raises a SyntaxError: foo(a = i for i in range(10))
452
Neal Norwitz708e51a2005-10-03 04:48:15 +0000453- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
454
Neal Norwitz11bd1192005-10-03 00:54:56 +0000455- SF Bug #887946: fix segfault when redirecting stdin from a directory.
456 Provide a warning when a directory is passed on the command line.
457
Neal Norwitz40d37812005-10-02 01:48:49 +0000458- Fix segfault with invalid coding.
459
460- SF bug #772896: unknown encoding results in MemoryError.
461
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000462- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000463 supported a __len__() method which evaluated to False when the iterator
464 was empty.
465
Guido van Rossum630db602005-09-20 18:49:54 +0000466- On 64-bit platforms, when __len__() returns a value that cannot be
467 represented as a C int, raise OverflowError.
468
Skip Montanarof8948ca2005-09-19 03:54:46 +0000469- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000470 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000471
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000472- SF bug #893549: parsing keyword arguments was broken with a few format
473 codes.
474
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000475- Changes donated by Elemental Security to make it work on AIX 5.3
476 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
477 bug #105470: test_pwd fails on 64bit system (Opteron).
478
Guido van Rossum539c6622005-09-14 17:49:54 +0000479- Changes donated by Elemental Security to make it work on HP-UX 11 on
480 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
481
Georg Brandl4550b8d2005-08-26 06:43:52 +0000482- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000483 (fixes bug #1119418).
484
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000485- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
486
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000487- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
488 exceptions that cause a function to exit.
489
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000490- The implementation of set() and frozenset() was revised to use its
491 own internal data structure. Memory consumption is reduced by 1/3
492 and there are modest speed-ups as well. The API is unchanged.
493
Tim Petersde7990b2005-07-17 23:45:23 +0000494- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
495
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000496- SF bug #1229429: PyObject_CallMethod failed to decrement some
497 reference counts in some error exit cases.
498
Tim Petersecc6e6a2005-07-10 22:30:55 +0000499- SF bug #1185883: Python's small-object memory allocator took over
500 a block managed by the platform C library whenever a realloc specified
501 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000502 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000503 portable way to copy data from the C-managed block into Python's
504 small-object space without risking a memory fault. Python's small-object
505 realloc now leaves such blocks under the control of the platform C
506 realloc.
507
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000508- SF bug #1232517: An overflow error was not detected properly when
509 attempting to convert a large float to an int in os.utime().
510
Raymond Hettinger3296e692005-06-29 23:29:56 +0000511- SF bug #1224347: hex longs now print with lowercase letters just
512 like their int counterparts.
513
Michael W. Hudson188d4362005-06-20 16:52:57 +0000514- SF bug #1163563: the original fix for bug #1010677 ("thread Module
515 Breaks PyGILState_Ensure()") broke badly in the case of multiple
516 interpreter states; back out that fix and do a better job (see
517 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
518 for a longer write-up of the problem).
519
Michael W. Hudsondf888462005-06-03 14:41:55 +0000520- SF patch #1180995: marshal now uses a binary format by default when
521 serializing floats.
522
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000523- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
524 the routines that promise to produce IEEE 754 binary representations
525 of floats now simply copy bytes around.
526
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000527- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
528 278.
529
Brett Cannonc3647ac2005-04-26 03:45:26 +0000530- patch #1109424: int, long, float, complex, and unicode now check for the
531 proper magic slot for type conversions when subclassed. Previously the
532 magic slot was ignored during conversion. Semantics now match the way
533 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000534 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000535 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000536 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000537
Barry Warsawc8d907c2005-04-19 23:43:40 +0000538- Descriptors defined in C with a PyGetSetDef structure, where the setter is
539 NULL, now raise an AttributeError when attempting to set or delete the
540 attribute. Previously a TypeError was raised, but this was inconsistent
541 with the equivalent pure-Python implementation.
542
Michael W. Hudson774479c2005-04-18 08:46:17 +0000543- It is now safe to call PyGILState_Release() before
544 PyEval_InitThreads() (note that if there is reason to believe there
545 are multiple threads around you still must call PyEval_InitThreads()
546 before using the Python API; this fix is for extension modules that
547 have no way of knowing if Python is multi-threaded yet).
548
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000549- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
550 disabled caused a crash.
551
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000552- Bug #1165306: instancemethod_new allowed the creation of a method
553 with im_class == im_self == NULL, which caused a crash when called.
554
Tim Petersecc6e6a2005-07-10 22:30:55 +0000555- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000556 fixes the crash seen in bug #1165761
557
Raymond Hettinger96229b12005-03-11 06:49:40 +0000558- Added two new builtins, any() and all().
559
Brett Cannon409d8f22005-03-05 06:47:57 +0000560- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000561 (e.g., ``class C(): pass`` is no longer a syntax error).
562 Patch #1176012 added support to the 'parser' module and 'compiler' package
563 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000564
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000565- Patch #1115086: Support PY_LONGLONG in structmember.
566
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000567- Bug #1155938: new style classes did not check that __init__() was
568 returning None.
569
Tim Petersecc6e6a2005-07-10 22:30:55 +0000570- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000571 ('\') with a specific error message.
572
Martin v. Löwisff232d72005-03-03 09:24:38 +0000573- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
574
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000575- Bug #1124295: the __name__ attribute of file objects was
576 inadvertently made inaccessible in restricted mode.
577
Tim Petersecc6e6a2005-07-10 22:30:55 +0000578- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000579 an ferror() call.
580
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000581- min() and max() now support key= arguments with the same meaning as in
582 list.sort().
583
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000584- The peephole optimizer now performs simple constant folding in expressions:
585 (2+3) --> (5).
586
Raymond Hettingera422c342005-01-11 03:03:27 +0000587- set and frozenset objects can now be marshalled. SF #1098985.
588
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000589- Bug #1077106: Poor argument checking could cause memory corruption
590 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000591
Jeremy Hyltonab630502005-02-04 18:44:06 +0000592- The parser did not complain about future statements in illegal
593 positions. It once again reports a syntax error if a future
594 statement occurs after anything other than a doc string.
595
Neil Schemenauercf52c072005-08-12 17:34:58 +0000596- Change the %s format specifier for str objects so that it returns a
597 unicode instance if the argument is not an instance of basestring and
598 calling __str__ on the argument returns a unicode instance.
599
Tim Petersf4e69282006-02-27 17:15:31 +0000600- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
601 current thread state when the auto-GIL-state machinery knows about
602 it (since the thread state is being deleted, continuing to remember it
603 can't help, but can hurt if another thread happens to get created with
604 the same thread id).

Georg Brandl828fdef2006-04-01 08:59:03 +0000811 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000812 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000813 module will not be built.
814
Tim Petersc17976e2006-04-01 00:26:53 +0000815- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
816 aren't officially supported here, and trying to use them will probably
817 raise an exception some day. But dicts have been allowed, and "mostly
818 worked", so support for them won't go away without warning.
819
Georg Brandl338ef7d2006-03-31 18:42:16 +0000820- Bug #1445068: getpass.getpass() can now be given an explicit stream
821 argument to specify where to write the prompt.
822

838
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000839- email 4.0 package now integrated. This is largely the same as the email 3.0
840 package that was included in Python 2.3, except that PEP 8 module names are
841 now used (e.g. mail.message instead of email.Message). The MIME classes
842 have been moved to a subpackage (e.g. email.mime.text instead of
843 email.MIMEText). The old names are still supported for now. Several
844 deprecated Message methods have been removed and lots of bugs have been
845 fixed. More details can be found in the email package documentation.
846
Walter Dörwald40108c92006-03-27 08:15:44 +0000847- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
848 (a subclass of tuple) that provides incremental decoders and encoders
849 (a way to use stateful codecs without the stream API). Python functions
850 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
851 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
852 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +0000854- Patch #1359365: Calling next() on a closed StringIO.String object raises
855 a ValueError instead of a StopIteration now (like file and cString.String do).
856 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
857 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000858

Tim Peterse3547fd2005-12-16 23:13:57 +0000931 SHA1, 224, 256, 384, and 512. Note that recent developments make the
932 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
933 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
934 Ronald L. Rivest offered this advice for Python:
935
936 "The consensus of researchers in this area (at least as
937 expressed at the NIST Hash Function Workshop 10/31/05),
938 is that SHA-256 is a good choice for the time being, but
939 that research should continue, and other alternatives may
940 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000941
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000942- Added a subset of Fredrik Lundh's ElementTree package. Available

1036
Raymond Hettinger68c04532005-06-10 11:05:19 +00001037- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001038 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001039 the generate_tokens() function now accepts a callable argument that
1040 terminates by raising StopIteration.
1041

Guido van Rossumd0641422005-02-03 15:01:24 +00001101- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1102 disables recursive traversal through instance attributes, which can
1103 be exploited in various ways.
1104
Tim Peterse3547fd2005-12-16 23:13:57 +00001105- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001106 flags on the HTTP listening socket.
1107

1119
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001120- Enhancements to the csv module:
1121
1122 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001123 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001124 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001125 + Dialect parameter parsing has been re-implemented to improve error
1126 reporting.
1127 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1128 dictates.
1129 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001130 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001131 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001132 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1133 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001134 + reader now allows \r characters to be quoted (previously it only allowed
1135 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001136 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001137 + Dialect classes passed to the module are no longer instantiated by
1138 the module before being parsed (the former validation scheme required
1139 this, but the mechanism was unreliable).
1140 + The dialect registry now contains instances of the internal
1141 C-coded dialect type, rather than references to python objects.
1142 + the internal c-coded dialect type is now immutable.
1143 + register_dialect now accepts the same keyword dialect specifications
1144 as the reader and writer, allowing the user to register dialects
1145 without first creating a dialect class.
1146 + a configurable limit to the size of parsed fields has been added -
1147 previously, an unmatched quote character could result in the entire
1148 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001149 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001150 the parser field size limit (returning the former limit). The initial
1151 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001152 + A line_num attribute has been added to the reader object, which tracks
1153 the number of lines read from the source iterator. This is not
1154 the same as the number of records returned, as records can span
1155 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001156 + reader and writer objects were not being registered with the cyclic-GC.
1157 This has been fixed.
1158
Brett Cannone6539c42005-01-08 02:43:53 +00001159- _DummyThread objects in the threading module now delete self.__block that is
1160 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1161 lock primitives tend to be limited in number and thus should not be wasted on
1162 a _DummyThread object. Fixes bug #1089632.
1163
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001164- The imghdr module now detects Exif files.
1165
Raymond Hettinger6065d322004-12-20 23:51:53 +00001166- StringIO.truncate() now correctly adjusts the size attribute.
1167 (Bug #951915).
1168
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001169- locale.py now uses an updated locale alias table (built using
1170 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1171 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001172 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001173
Raymond Hettinger3557f422004-12-07 12:02:02 +00001174- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1175
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001176- the pickle module no longer accepts the deprecated None option in the
1177 args tuple returned by __reduce__().
1178
Brett Cannon84667c02004-12-07 03:25:18 +00001179- optparse now optionally imports gettext. This allows its use in setup.py.
1180
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001181- the pickle module no longer uses the deprecated bin parameter.
1182
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001183- the shelve module no longer uses the deprecated binary parameter.
1184
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001185- the pstats module no longer uses the deprecated ignore() method.
1186
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001187- the filecmp module no longer uses the deprecated use_statcache argument.
1188
Raymond Hettinger664347b2004-12-04 21:21:53 +00001189- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1190 extended or overridden by subclasses. Formerly, the subclassed method would
1191 be ignored by the rest of the module. (Bug #1078905).
1192
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001193- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001194 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001195
Walter Dörwald36733692004-12-22 12:50:50 +00001196- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1197 once when a size argument is given. This prevents a buffer overflow in the
1198 tokenizer with very long source lines.
1199
Barry Warsaw538561e2006-01-01 21:48:54 +00001200- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1201 immediately after creating the object, without any intervening
1202 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001203
Skip Montanaro05885812005-01-16 20:48:27 +00001204- The reconvert.quote function can now emit triple-quoted strings. The
1205 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001206
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001207- ``UserString.MutableString`` now supports negative indices in
1208 ``__setitem__`` and ``__delitem__``
1209
Greg Ward40407942005-03-05 02:53:17 +00001210- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1211 correctly.
1212
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001213- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1214 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1215 character even if the user has passed a size parameter to get a proper
1216 line ending. Remove the special handling of a "\r\n" that has been split
1217 between two lines.
1218
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001219- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1220 about illegal code points. The codec now supports PEP 293 style error
1221 handlers.
1222
Walter Dörwald78a78b02005-09-01 12:04:29 +00001223- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001224 from the input stream, so that the output is a byte string in the correct
1225 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001226
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001227- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1228 considering it exactly like a '*'.
1229
Walter Dörwald007f8df2005-10-09 19:42:27 +00001230- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1231 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001232
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001233- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1234
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001235- Patch #1413711: Certain patterns of differences were making difflib
1236 touch the recursion limit.
1237
Walter Dörwald58917a62006-03-31 15:26:22 +00001238- Bug #947906: An object oriented interface has been added to the calendar
1239 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001240 called as a script (e.g. via ``python -mcalendar``). Localized month and
1241 weekday names can be ouput (even if an exotic encoding is used) using
1242 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001243
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244Build
1245-----
1246
Neal Norwitz602d3392006-03-31 08:21:40 +00001247- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1248 by using -mieee gcc option.
1249
Martin v. Löwis86d66262006-02-17 08:40:11 +00001250- Patch #1432345: Make python compile on DragonFly.
1251
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001252- Build support for Win64-AMD64 was added.
1253
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001254- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1255
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001256- Patch #881820: look for openpty and forkpty also in libbsd.
1257
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001258- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1259 The zlib module is now builtin on Windows.
1260
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001261- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1262
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001263- Bug #1189330: configure did not correctly determine the necessary
1264 value of LINKCC if python was built with GCC 4.0.
1265
Trent Mick8321b422005-07-26 02:29:21 +00001266- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1267 vulnerability in zlib 1.2.1 and 1.2.2.
1268
Brett Cannon08cd5982005-04-24 22:26:38 +00001269- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1270 flags that change binary compatibility. Changes were also made to
1271 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001272 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001273
Bob Ippolitoed233462005-03-29 13:47:59 +00001274- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1275 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1276 no longer exists). This configure patch makes things right.
1277
Martin v. Löwise2713be2005-03-08 15:03:08 +00001278- Bug #1158607: Build with --disable-unicode again.
1279
Brett Cannon46d96232005-02-16 00:07:19 +00001280- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1281 defined. Discovered as a result of not being able to build on OS X.
1282
Brett Cannon516592f2004-12-07 00:42:59 +00001283- setup.py now uses the directories specified in LDFLAGS using the -L option
1284 and in CPPFLAGS using the -I option for adding library and include
1285 directories, respectively, for compiling extension modules against. This has
1286 led to the core being compiled using the values in CPPFLAGS. It also removes
1287 the need for the special-casing of both DarwinPorts and Fink for darwin since
1288 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1289 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1290 Fink, ``-I/opt/local/include`` for DarwinPorts).
1291
Brett Cannon43802422005-02-10 20:48:03 +00001292- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1293 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1294 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1295 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001297C API
1298-----
1299
Tim Petersc9d78aa2006-03-26 23:27:58 +00001300- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1301 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1302 is obtained via the ``PyObject_`` family, it must be released via the
1303 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1304 always been officially true, but when Python's small-object allocator was
1305 introduced, an attempt was made to cater to a few extension modules
1306 discovered at the time that obtained memory via ``PyObject_New`` but
1307 released it via ``PyMem_DEL``. It's years later, and if such code still
1308 exists it will fail now (probably with segfaults, but calling wrong
1309 low-level memory management functions can yield many symptoms).
1310
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001311- Added a C API for set and frozenset objects.
1312
Raymond Hettinger66517482004-12-03 11:45:13 +00001313- Removed PyRange_New().
1314
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001315- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1316 mapping argument now. This string is used as a mapping table. Byte values
1317 greater than the length of the string and 0xFFFE are treated as undefined
1318 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001325
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001326- Patch #1276356: New resource "urlfetch" is implemented. This enables
