Neal Norwitz7a5fc282006-05-15 06:48:14 +000010*Release date: XX-MAY-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Tim Peters696cf432006-05-24 21:10:40 +000015- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
16 of-2 bases. The largest speedup is for inputs with about 1000 decimal
17 digits. Conversion from non-power-of-2 bases remains quadratic-time in
18 the number of input digits (it was and remains linear-time for bases
19 2, 4, 8, 16 and 32).
20
Tim Petersb713ec22006-05-23 18:45:30 +000021- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
22 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
23 an integer close to ``sys.maxint``. This was repaired by patch
24 #1335972, which also gives a nice speedup.
25
Richard Jonescebbefc2006-05-23 18:28:17 +000026- Patch #1337051: reduced size of frame objects.
27
28- PyErr_NewException now accepts a tuple of base classes as its
29 "base" parameter.
30
Richard Jones7c88dcc2006-05-23 10:37:38 +000031- Patch #876206: function call speedup by retaining allocated frame
32 objects.
33
Georg Brandl7b90e162006-05-18 07:01:27 +000034- Bug #1462152: file() now checks more thoroughly for invalid mode
35 strings and removes a possible "U" before passing the mode to the
36 C library function.
37
Neal Norwitz1004a532006-05-15 07:17:23 +000038- Patch #1488312, Fix memory alignment problem on SPARC in unicode
39
Neal Norwitz373f0a72006-05-15 07:04:36 +000040- Bug #1487966: Fix SystemError with conditional expression in assignment
41
Martin v. Löwis879768d2006-05-11 13:28:43 +000042- WindowsError now has two error code attributes: errno, which carries
43 the error values from errno.h, and winerror, which carries the error
44 values from winerror.h. Previous versions put the winerror.h values
45 (from GetLastError()) into the errno attribute.
46
Martin v. Löwis77736712006-05-04 05:51:03 +000047- Patch #1475845: Raise IndentationError for unexpected indent.
48
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000049- Patch #1479181: split open() and file() from being aliases for each other.
50
Neal Norwitz7a5fc282006-05-15 06:48:14 +000051Extension Modules
52-----------------
53
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000054- Patch #1493701: performance enhancements for struct module.
55
Georg Brandl378d5922006-05-17 14:26:50 +000056- Patch #1490224: time.altzone is now set correctly on Cygwin.
57
Georg Brandl8d3342b2006-05-16 07:38:27 +000058- Patch #1435422: zlib's compress and decompress objects now have a
59 copy() method.
60
Neal Norwitz7a5fc282006-05-15 06:48:14 +000061- On Win32, os.listdir now supports arbitrarily-long Unicode path names
62 (up to the system limit of 32K characters).
63
64- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
65 As a result, these functions now raise WindowsError instead of OSError.
66
67- Calling Tk_Init twice is refused if the first call failed as that
68 may deadlock.
69
70Library
71-------
72
Bob Ippolito7298f272006-05-23 18:43:47 +000073- Patch #1281707: speed up gzip.readline.
74
Georg Brandlb89316f2006-05-17 15:51:16 +000075- Patch #1180296: Two new functions were added to the locale module:
76 format_string() to get the effect of "format % items" but locale-aware,
77 and currency() to format a monetary number with currency sign.
78
Georg Brandle3a25832006-05-17 14:56:04 +000079- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
80 and several features added, such as speed and geometry control.
81
Georg Brandl49c8f4c2006-05-15 19:30:35 +000082- Patch #1488881: add support for external file objects in bz2 compressed
83 tarfiles.
84
Neal Norwitz7a5fc282006-05-15 06:48:14 +000085- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
86 stdout arguments, making it possible to redirect input and output
87 for remote debugging.
88
89- Patch #1484695: Update the tarfile module to version 0.8. This fixes
90 a couple of issues, notably handling of long file names using the
91 GNU LONGNAME extension.
92
93- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
94 new flag when ``name`` is already the name of an option flag.
95
96- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
97 package.
98
99- Patch #1472854: make the rlcompleter.Completer class usable on non-
100 UNIX platforms.
101
102- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

125What's New in Python 2.5 alpha 2?
126=================================
127
128*Release date: 27-APR-2006*
129
130Core and builtins
131-----------------
132
Thomas Heller1b046642006-04-18 18:51:06 +0000133- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
134 by converting these apis from macros into exported functions again:
135
136 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
137 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
138 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
139 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
140 PyRun_String Py_CompileString
141
Martin v. Löwis45294a92006-04-18 06:24:08 +0000142- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
143
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000144- All uses of PyStructSequence_InitType have been changed to initialize
145 the type objects only once, even if the interpreter is initialized
146 multiple times.
147
Neal Norwitz61546162006-04-14 05:20:28 +0000148- Bug #1454485, array.array('u') could crash the interpreter. This was
149 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
150 to unicode when it didn't make sense. 'u#' now requires a unicode string.
151
152- Py_UNICODE is unsigned. It was always documented as unsigned, but
153 due to a bug had a signed value in previous versions.
154
Tim Peters3a5e8b12006-04-11 01:44:07 +0000155- Patch #837242: ``id()`` of any Python object always gives a positive
156 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
157 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000158 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000159 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000160
Tim Peters3a5e8b12006-04-11 01:44:07 +0000161 def __hash__(self):
162 return id(self) # WRONG
163
164 because a hash result must be a (short) Python int but it was always
165 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000166 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000167 was always usable as a hash value before this patch. That's no longer
168 necessarily so.
169
170- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000171 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000172 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000173 #1454844)
174
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000175- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
176 involving generators that have paused outside of any ``try`` or ``with``
177 blocks. (In 2.5a1, a paused generator that was part of a reference
178 cycle could not be garbage collected, regardless of whether it was
179 paused in a ``try`` or ``with`` block.)

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000184- Patch #1191065: Fix preprocessor problems on systems where recvfrom
185 is a macro.
186
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000187- Bug #1467952: os.listdir() now correctly raises an error if readdir()
188 fails with an error condition.
189
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000190- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
191
192- Bug #1117761: bsddb.*open() no longer raises an exception when using
193 the cachesize parameter.
194
195- Bug #1149413: bsddb.*open() no longer raises an exception when using
196 a temporary db (file=None) with the 'n' flag to truncate on open.
197
198- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
199 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000200
Armin Rigoa9017c32006-04-19 11:50:27 +0000201- Patch #1062014: AF_UNIX sockets under Linux have a special
202 abstract namespace that is now fully supported.
203
Anthony Baxter51bcb682006-04-05 14:51:42 +0000204Library
205-------
206
Tim Peters711bf302006-04-25 03:31:36 +0000207- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
208 a doctest to be skipped (the code is not run, and the expected output
209 or exception is ignored).
210
Nick Coghlanda2268f2006-04-24 04:37:15 +0000211- Fixed contextlib.nested to cope with exceptions being raised and
212 caught inside exit handlers.
213
Greg Wardab05edc2006-04-23 03:47:58 +0000214- Updated optparse module to Optik 1.5.1 (allow numeric constants in
215 hex, octal, or binary; add ``append_const`` action; keep going if
216 gettext cannot be imported; added ``OptionParser.destroy()`` method;
217 added ``epilog`` for better help generation).
218
Tim Peters21fbd572006-04-21 21:18:10 +0000219- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
220 called from a thread spawned as a side effect of importing a module.
221
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000222- The pydoc module now supports documenting packages contained in
223 .zip or .egg files.
224
225- The pkgutil module now has several new utility functions, such
226 as ``walk_packages()`` to support working with packages that are either
227 in the filesystem or zip files.
228
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000229- The mailbox module can now modify and delete messages from
230 mailboxes, in addition to simply reading them. Thanks to Gregory
231 K. Johnson for writing the code, and to the 2005 Google Summer of
232 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000233
Tim Petersc7605f22006-04-17 21:12:33 +0000234- The ``__del__`` method of class ``local`` in module ``_threading_local``
235 returned before accomplishing any of its intended cleanup.
236
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000237- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000241- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
242
Anthony Baxtere29002c2006-04-12 12:07:31 +0000243- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
244 Windows. Bug #1469163.
245
Phillip J. Eby47032112006-04-11 01:07:43 +0000246- The warnings, linecache, inspect, traceback, site, and doctest modules
247 were updated to work correctly with modules imported from zipfiles or
248 via other PEP 302 __loader__ objects.
249
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000250- Patch #1467770: Reduce usage of subprocess._active to processes which
251 the application hasn't waited on.
252
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000253- Patch #1462222: Fix Tix.Grid.

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000270- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
271 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000272 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000273 CXX from --with-cxx-main, see description in README.
274
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000275- Patch #1429775: Link extension modules with the shared libpython.
276

Nick Coghlanda2268f2006-04-24 04:37:15 +0000286- test_contextlib now checks contextlib.nested can cope with exceptions
287 being raised and caught inside exit handlers.
288
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000289- test_cmd_line now checks operation of the -m and -c command switches
290
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000291- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
292 it separately and by hand. It also wasn't cleaning up its changes to
293 the current Decimal context.
294
Thomas Woutersabd08882006-04-26 15:53:30 +0000295- regrtest.py now has a -M option to run tests that test the new limits of
296 containers, on 64-bit architectures. Running these tests is only sensible
297 on 64-bit machines with more than two gigabytes of memory. The argument
298 passed is the maximum amount of memory for the tests to use.

Nick Coghlan43832302006-04-23 17:04:07 +0000327- PEP 338: -m command line switch now delegates to runpy.run_module
328 allowing it to support modules in packages and zipfiles
329
Martin v. Löwisc661b882006-04-20 04:54:23 +0000330- On Windows, .DLL is not an accepted file name extension for
331 extension modules anymore; extensions are only found if they
332 end in .PYD.
333
Martin v. Löwisea62d252006-04-03 10:56:49 +0000334- Bug #1421664: sys.stderr.encoding is now set to the same value as

Neal Norwitz92e212f2006-04-03 04:48:37 +0000337- __import__ accepts keyword arguments.
338
Georg Brandlccadf842006-03-31 18:54:53 +0000339- Patch #1460496: round() now accepts keyword arguments.
340
Anthony Baxter262c00a2006-03-30 10:53:17 +0000341- Fixed bug #1459029 - unicode reprs were double-escaped.
342
Hye-Shik Changd478f342006-03-23 12:32:36 +0000343- Patch #1396919: The system scope threads are reenabled on FreeBSD
344 5.4 and later versions.
345
Neal Norwitze98ccf62006-03-23 05:39:47 +0000346- Bug #1115379: Compiling a Unicode string with an encoding declaration
347 now gives a SyntaxError.
348
Georg Brandlabd1ff82006-03-18 07:59:59 +0000349- Previously, Python code had no easy way to access the contents of a
350 cell object. Now, a ``cell_contents`` attribute has been added
351 (closes patch #1170323).
352
Tim Peterscf79aac2006-03-16 01:14:46 +0000353- Patch #1123430: Python's small-object allocator now returns an arena to
354 the system ``free()`` when all memory within an arena becomes unused
355 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
356 freed. Some applications will see a drop in virtual memory size now,
357 especially long-running applications that, from time to time, temporarily
358 use a large number of small objects. Note that when Python returns an
359 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000360 platform C library will in turn return that memory to the operating system.
361 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000362 appears to be effective at least on Microsoft C and gcc-based systems.
363 Thanks to Evan Jones for hard work and patience.
364
Georg Brandl533ff6f2006-03-08 18:09:27 +0000365- Patch #1434038: property() now uses the getter's docstring if there is
366 no "doc" argument given. This makes it possible to legitimately use
367 property() as a decorator to produce a read-only property.
368
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000369- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
370 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
371 of requiring an int or long in slicing and a few other contexts, enabling
372 other objects (e.g. Numeric Python's integers) to be used as slice indices.
373
Neal Norwitz995acdf2006-03-07 05:01:00 +0000374- Fixed various bugs reported by Coverity's Prevent tool.
375
Brett Cannonbf364092006-03-01 04:25:17 +0000376- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
377 new exception base class, BaseException, which has a new message attribute.
378 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
379 Raising a string exception now raises a DeprecationWarning.
380
Thomas Woutersfb609f42006-02-28 16:37:25 +0000381- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
382 explicitly relative, using 'from .module import name' to mean 'from the same
383 package as this module is in. Imports without dots still default to the
384 old relative-then-absolute, unless 'from __future__ import
385 absolute_import' is used.
386
Brett Cannona7446e32006-02-27 23:39:10 +0000387- Properly check if 'warnings' raises an exception (usually when a filter set
388 to "error" is triggered) when raising a warning for raising string
389 exceptions.
390
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000391- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000392 The name was removed from Include/code.h.
393
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000394- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000395
Guido van Rossum1968ad32006-02-25 22:38:04 +0000396- Patch 1433928:
397 - The copy module now "copies" function objects (as atomic objects).
398 - dict.__getitem__ now looks for a __missing__ hook before raising
399 KeyError.
400
Tim Peters84ef21c2006-02-28 20:39:06 +0000401- PEP 343: with statement implemented. Needs ``from __future__ import
402 with_statement``. Use of 'with' as a variable will generate a warning.
403 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000404 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000405 The following objects have __context__ methods:
406 - The built-in file type.
407 - The thread.LockType type.
408 - The following types defined by the threading module:
409 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
410 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000411
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000412- Fix the encodings package codec search function to only search
413 inside its own package. Fixes problem reported in patch #1433198.
414
415 Note: Codec packages should implement and register their own
416 codec search function. PEP 100 has the details.
417
Martin v. Löwis18e16552006-02-15 17:27:45 +0000418- PEP 353: Using ssize_t as the index type.
419
Neal Norwitzfc76d632006-01-10 06:03:13 +0000420- Patch #1400181, fix unicode string formatting to not use the locale.
421 This is how string objects work. u'%f' could use , instead of .
422 for the decimal point. Now both strings and unicode always use periods.
423
Neal Norwitz671b9e32006-01-09 07:07:12 +0000424- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
425 configure would break checking curses.h.
426
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000427- Bug #959576: The pwd module is now builtin. This allows Python to be
428 built on UNIX platforms without $HOME set.
429
Neal Norwitzc10978f2005-12-19 06:07:16 +0000430- Bug #1072182, fix some potential problems if characters are signed.
431
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000432- Bug #889500, fix line number on SyntaxWarning for global declarations.
433
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000434- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
435
Neal Norwitze7214a12005-12-18 05:03:17 +0000436- Support for converting hex strings to floats no longer works.
437 This was not portable. float('0x3') now raises a ValueError.
438
Barry Warsaw2a38a862005-12-18 01:27:35 +0000439- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000440 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000441 is now displayed in interactive prompt banner.
442
Georg Brandlfa166682005-12-17 21:45:17 +0000443- Implementation of PEP 341 - Unification of try/except and try/finally.
444 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000445 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000446
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000447- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
448 now encodes backslash correctly.
449
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000450- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
451
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000452- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000453 and long longs.
454
Neal Norwitz67715f02005-11-09 06:59:35 +0000455- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000456 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000457 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000458
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000459- Replaced most Unicode charmap codecs with new ones using the
460 new Unicode translate string feature in the builtin charmap
461 codec; the codecs were created from the mapping tables available
462 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
463 encodings now include a mapping for the Apple logo)
464
Tim Peterse3547fd2005-12-16 23:13:57 +0000465- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000466
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000467- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000468
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000469- A new AST parser implementation was completed. The abstract
470 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000471 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000472
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000473- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000474 The following code now raises a SyntaxError: foo(a = i for i in range(10))
475
Neal Norwitz708e51a2005-10-03 04:48:15 +0000476- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
477
Neal Norwitz11bd1192005-10-03 00:54:56 +0000478- SF Bug #887946: fix segfault when redirecting stdin from a directory.
479 Provide a warning when a directory is passed on the command line.
480
Neal Norwitz40d37812005-10-02 01:48:49 +0000481- Fix segfault with invalid coding.
482
483- SF bug #772896: unknown encoding results in MemoryError.
484
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000485- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000486 supported a __len__() method which evaluated to False when the iterator
487 was empty.
488
Guido van Rossum630db602005-09-20 18:49:54 +0000489- On 64-bit platforms, when __len__() returns a value that cannot be
490 represented as a C int, raise OverflowError.
491
Skip Montanarof8948ca2005-09-19 03:54:46 +0000492- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000493 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000494
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000495- SF bug #893549: parsing keyword arguments was broken with a few format
496 codes.
497
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000498- Changes donated by Elemental Security to make it work on AIX 5.3
499 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
500 bug #105470: test_pwd fails on 64bit system (Opteron).
501
Guido van Rossum539c6622005-09-14 17:49:54 +0000502- Changes donated by Elemental Security to make it work on HP-UX 11 on
503 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
504
Georg Brandl4550b8d2005-08-26 06:43:52 +0000505- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000506 (fixes bug #1119418).
507
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000508- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
509
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000510- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
511 exceptions that cause a function to exit.
512
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000513- The implementation of set() and frozenset() was revised to use its
514 own internal data structure. Memory consumption is reduced by 1/3
515 and there are modest speed-ups as well. The API is unchanged.
516
Tim Petersde7990b2005-07-17 23:45:23 +0000517- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
518
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000519- SF bug #1229429: PyObject_CallMethod failed to decrement some
520 reference counts in some error exit cases.
521
Tim Petersecc6e6a2005-07-10 22:30:55 +0000522- SF bug #1185883: Python's small-object memory allocator took over
523 a block managed by the platform C library whenever a realloc specified
524 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000525 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000526 portable way to copy data from the C-managed block into Python's
527 small-object space without risking a memory fault. Python's small-object
528 realloc now leaves such blocks under the control of the platform C
529 realloc.
530
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000531- SF bug #1232517: An overflow error was not detected properly when
532 attempting to convert a large float to an int in os.utime().
533
Raymond Hettinger3296e692005-06-29 23:29:56 +0000534- SF bug #1224347: hex longs now print with lowercase letters just
535 like their int counterparts.
536
Michael W. Hudson188d4362005-06-20 16:52:57 +0000537- SF bug #1163563: the original fix for bug #1010677 ("thread Module
538 Breaks PyGILState_Ensure()") broke badly in the case of multiple
539 interpreter states; back out that fix and do a better job (see
540 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
541 for a longer write-up of the problem).
542
Michael W. Hudsondf888462005-06-03 14:41:55 +0000543- SF patch #1180995: marshal now uses a binary format by default when
544 serializing floats.
545
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000546- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
547 the routines that promise to produce IEEE 754 binary representations
548 of floats now simply copy bytes around.
549
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000550- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
551 278.
552
Brett Cannonc3647ac2005-04-26 03:45:26 +0000553- patch #1109424: int, long, float, complex, and unicode now check for the
554 proper magic slot for type conversions when subclassed. Previously the
555 magic slot was ignored during conversion. Semantics now match the way
556 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000557 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000558 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000559 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000560
Barry Warsawc8d907c2005-04-19 23:43:40 +0000561- Descriptors defined in C with a PyGetSetDef structure, where the setter is
562 NULL, now raise an AttributeError when attempting to set or delete the
563 attribute. Previously a TypeError was raised, but this was inconsistent
564 with the equivalent pure-Python implementation.
565
Michael W. Hudson774479c2005-04-18 08:46:17 +0000566- It is now safe to call PyGILState_Release() before
567 PyEval_InitThreads() (note that if there is reason to believe there
568 are multiple threads around you still must call PyEval_InitThreads()
569 before using the Python API; this fix is for extension modules that
570 have no way of knowing if Python is multi-threaded yet).
571
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000572- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
573 disabled caused a crash.
574
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000575- Bug #1165306: instancemethod_new allowed the creation of a method
576 with im_class == im_self == NULL, which caused a crash when called.
577
Tim Petersecc6e6a2005-07-10 22:30:55 +0000578- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000579 fixes the crash seen in bug #1165761
580
Raymond Hettinger96229b12005-03-11 06:49:40 +0000581- Added two new builtins, any() and all().
582
Brett Cannon409d8f22005-03-05 06:47:57 +0000583- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000584 (e.g., ``class C(): pass`` is no longer a syntax error).
585 Patch #1176012 added support to the 'parser' module and 'compiler' package
586 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000587
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000588- Patch #1115086: Support PY_LONGLONG in structmember.
589
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000590- Bug #1155938: new style classes did not check that __init__() was
591 returning None.
592
Tim Petersecc6e6a2005-07-10 22:30:55 +0000593- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000594 ('\') with a specific error message.
595
Martin v. Löwisff232d72005-03-03 09:24:38 +0000596- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
597
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000598- Bug #1124295: the __name__ attribute of file objects was
599 inadvertently made inaccessible in restricted mode.
600
Tim Petersecc6e6a2005-07-10 22:30:55 +0000601- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000602 an ferror() call.
603
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000604- min() and max() now support key= arguments with the same meaning as in
605 list.sort().
606
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000607- The peephole optimizer now performs simple constant folding in expressions:

609
Raymond Hettingera422c342005-01-11 03:03:27 +0000610- set and frozenset objects can now be marshalled. SF #1098985.
611

Jeremy Hyltonab630502005-02-04 18:44:06 +0000615- The parser did not complain about future statements in illegal
616 positions. It once again reports a syntax error if a future
617 statement occurs after anything other than a doc string.
618
Neil Schemenauercf52c072005-08-12 17:34:58 +0000619- Change the %s format specifier for str objects so that it returns a
620 unicode instance if the argument is not an instance of basestring and
621 calling __str__ on the argument returns a unicode instance.
622
Tim Petersf4e69282006-02-27 17:15:31 +0000623- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
624 current thread state when the auto-GIL-state machinery knows about
625 it (since the thread state is being deleted, continuing to remember it
626 can't help, but can hurt if another thread happens to get created with
627 the same thread id).

761 for large or negative values.
762
Tim Petersecc6e6a2005-07-10 22:30:55 +0000763- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingerb2594052004-12-05 09:25:51 +0000806- itertools.islice() now accepts None for the start and step arguments.
807 This allows islice() to work more readily with slices:

817-------
818
Nick Coghlan43832302006-04-23 17:04:07 +0000819- PEP 338: new module runpy defines a run_module function to support
820 executing modules which provide access to source code or a code object
821 via the PEP 302 import mechanisms.
822
Anthony Baxter93f5b932006-04-03 08:05:07 +0000823- The email module's parsedate_tz function now sets the daylight savings
824 flag to -1 (unknown) since it can't tell from the date whether it should

831 in attribute values.
832
Anthony Baxterc51ee692006-04-01 00:57:31 +0000833- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000834 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000835 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000836 module will not be built.
837
Tim Petersc17976e2006-04-01 00:26:53 +0000838- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
839 aren't officially supported here, and trying to use them will probably
840 raise an exception some day. But dicts have been allowed, and "mostly
841 worked", so support for them won't go away without warning.
842
Georg Brandl338ef7d2006-03-31 18:42:16 +0000843- Bug #1445068: getpass.getpass() can now be given an explicit stream
844 argument to specify where to write the prompt.
845
Georg Brandl22ec80b2006-03-31 18:25:44 +0000846- Patch #1462313, bug #1443328: the pickle modules now can handle classes

861
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000862- email 4.0 package now integrated. This is largely the same as the email 3.0
863 package that was included in Python 2.3, except that PEP 8 module names are
864 now used (e.g. mail.message instead of email.Message). The MIME classes
865 have been moved to a subpackage (e.g. email.mime.text instead of
866 email.MIMEText). The old names are still supported for now. Several
867 deprecated Message methods have been removed and lots of bugs have been
868 fixed. More details can be found in the email package documentation.
869
Walter Dörwald40108c92006-03-27 08:15:44 +0000870- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
871 (a subclass of tuple) that provides incremental decoders and encoders
872 (a way to use stateful codecs without the stream API). Python functions
873 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
874 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
875 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000876
Walter Dörwald067db482006-03-15 22:17:27 +0000877- Patch #1359365: Calling next() on a closed StringIO.String object raises
878 a ValueError instead of a StopIteration now (like file and cString.String do).
879 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
880 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000881
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000882- A regrtest option -w was added to re-run failed tests in verbose mode.

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

Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001146 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001147 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001148 + Dialect parameter parsing has been re-implemented to improve error
1149 reporting.
1150 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1151 dictates.
1152 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001153 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001154 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001155 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1156 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001157 + reader now allows \r characters to be quoted (previously it only allowed
1158 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001159 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001160 + Dialect classes passed to the module are no longer instantiated by
1161 the module before being parsed (the former validation scheme required
1162 this, but the mechanism was unreliable).
1163 + The dialect registry now contains instances of the internal
1164 C-coded dialect type, rather than references to python objects.
1165 + the internal c-coded dialect type is now immutable.
1166 + register_dialect now accepts the same keyword dialect specifications
1167 as the reader and writer, allowing the user to register dialects
1168 without first creating a dialect class.
1169 + a configurable limit to the size of parsed fields has been added -
1170 previously, an unmatched quote character could result in the entire
1171 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001172 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001173 the parser field size limit (returning the former limit). The initial
1174 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001175 + A line_num attribute has been added to the reader object, which tracks
1176 the number of lines read from the source iterator. This is not
1177 the same as the number of records returned, as records can span
1178 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001179 + reader and writer objects were not being registered with the cyclic-GC.
1180 This has been fixed.
1181
Brett Cannone6539c42005-01-08 02:43:53 +00001182- _DummyThread objects in the threading module now delete self.__block that is
1183 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1184 lock primitives tend to be limited in number and thus should not be wasted on
1185 a _DummyThread object. Fixes bug #1089632.
1186
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001187- The imghdr module now detects Exif files.
1188
Raymond Hettinger6065d322004-12-20 23:51:53 +00001189- StringIO.truncate() now correctly adjusts the size attribute.
1190 (Bug #951915).
1191
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001192- locale.py now uses an updated locale alias table (built using
1193 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1194 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001195 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001196
Raymond Hettinger3557f422004-12-07 12:02:02 +00001197- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1198
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001199- the pickle module no longer accepts the deprecated None option in the
1200 args tuple returned by __reduce__().
1201
Brett Cannon84667c02004-12-07 03:25:18 +00001202- optparse now optionally imports gettext. This allows its use in setup.py.
1203
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001204- the pickle module no longer uses the deprecated bin parameter.
1205
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001206- the shelve module no longer uses the deprecated binary parameter.
1207
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001208- the pstats module no longer uses the deprecated ignore() method.
1209
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001210- the filecmp module no longer uses the deprecated use_statcache argument.
1211
Raymond Hettinger664347b2004-12-04 21:21:53 +00001212- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1213 extended or overridden by subclasses. Formerly, the subclassed method would
1214 be ignored by the rest of the module. (Bug #1078905).
1215
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001216- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001217 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001218
Walter Dörwald36733692004-12-22 12:50:50 +00001219- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1220 once when a size argument is given. This prevents a buffer overflow in the
1221 tokenizer with very long source lines.
1222
Barry Warsaw538561e2006-01-01 21:48:54 +00001223- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1224 immediately after creating the object, without any intervening
1225 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001226
Skip Montanaro05885812005-01-16 20:48:27 +00001227- The reconvert.quote function can now emit triple-quoted strings. The
1228 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001229
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001230- ``UserString.MutableString`` now supports negative indices in
1231 ``__setitem__`` and ``__delitem__``
1232
Greg Ward40407942005-03-05 02:53:17 +00001233- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1234 correctly.
1235
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001236- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1237 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1238 character even if the user has passed a size parameter to get a proper
1239 line ending. Remove the special handling of a "\r\n" that has been split
1240 between two lines.
1241
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001242- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1243 about illegal code points. The codec now supports PEP 293 style error
1244 handlers.
1245
Walter Dörwald78a78b02005-09-01 12:04:29 +00001246- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001247 from the input stream, so that the output is a byte string in the correct
1248 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001249
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001250- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1251 considering it exactly like a '*'.
1252
Walter Dörwald007f8df2005-10-09 19:42:27 +00001253- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1254 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001255
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001256- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1257
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001258- Patch #1413711: Certain patterns of differences were making difflib
1259 touch the recursion limit.
1260
Walter Dörwald58917a62006-03-31 15:26:22 +00001261- Bug #947906: An object oriented interface has been added to the calendar
1262 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001263 called as a script (e.g. via ``python -mcalendar``). Localized month and
1264 weekday names can be ouput (even if an exotic encoding is used) using
1265 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001266
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001267Build

1269
Neal Norwitz602d3392006-03-31 08:21:40 +00001270- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1271 by using -mieee gcc option.
1272

1274
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001275- Build support for Win64-AMD64 was added.
1276
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001277- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1278
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001279- Patch #881820: look for openpty and forkpty also in libbsd.
1280
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001281- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1282 The zlib module is now builtin on Windows.
1283
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001284- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1285
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001286- Bug #1189330: configure did not correctly determine the necessary
1287 value of LINKCC if python was built with GCC 4.0.
1288
Trent Mick8321b422005-07-26 02:29:21 +00001289- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1290 vulnerability in zlib 1.2.1 and 1.2.2.
1291
Brett Cannon08cd5982005-04-24 22:26:38 +00001292- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1293 flags that change binary compatibility. Changes were also made to
1294 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001295 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001296
Bob Ippolitoed233462005-03-29 13:47:59 +00001297- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1298 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1299 no longer exists). This configure patch makes things right.
1300
Martin v. Löwise2713be2005-03-08 15:03:08 +00001301- Bug #1158607: Build with --disable-unicode again.
1302
Brett Cannon46d96232005-02-16 00:07:19 +00001303- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1304 defined. Discovered as a result of not being able to build on OS X.
1305
Brett Cannon516592f2004-12-07 00:42:59 +00001306- setup.py now uses the directories specified in LDFLAGS using the -L option
1307 and in CPPFLAGS using the -I option for adding library and include
1308 directories, respectively, for compiling extension modules against. This has
1309 led to the core being compiled using the values in CPPFLAGS. It also removes
1310 the need for the special-casing of both DarwinPorts and Fink for darwin since
1311 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1312 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1313 Fink, ``-I/opt/local/include`` for DarwinPorts).
1314
Brett Cannon43802422005-02-10 20:48:03 +00001315- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1316 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1317 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1318 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001320C API
1321-----
1322
Tim Petersc9d78aa2006-03-26 23:27:58 +00001323- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1324 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1325 is obtained via the ``PyObject_`` family, it must be released via the
1326 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1327 always been officially true, but when Python's small-object allocator was
1328 introduced, an attempt was made to cater to a few extension modules
1329 discovered at the time that obtained memory via ``PyObject_New`` but
1330 released it via ``PyMem_DEL``. It's years later, and if such code still
1331 exists it will fail now (probably with segfaults, but calling wrong
1332 low-level memory management functions can yield many symptoms).
1333
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001334- Added a C API for set and frozenset objects.
1335
Raymond Hettinger66517482004-12-03 11:45:13 +00001336- Removed PyRange_New().
1337
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001338- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1339 mapping argument now. This string is used as a mapping table. Byte values
1340 greater than the length of the string and 0xFFFE are treated as undefined
1341 mappings.
