12Core and builtins
13-----------------
14
Neal Norwitz1004a532006-05-15 07:17:23 +000015- Patch #1488312, Fix memory alignment problem on SPARC in unicode
16
Neal Norwitz373f0a72006-05-15 07:04:36 +000017- Bug #1487966: Fix SystemError with conditional expression in assignment
18
Martin v. Löwis879768d2006-05-11 13:28:43 +000019- WindowsError now has two error code attributes: errno, which carries
20 the error values from errno.h, and winerror, which carries the error
21 values from winerror.h. Previous versions put the winerror.h values
22 (from GetLastError()) into the errno attribute.
23
Martin v. Löwis77736712006-05-04 05:51:03 +000024- Patch #1475845: Raise IndentationError for unexpected indent.
25
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000026- Patch #1479181: split open() and file() from being aliases for each other.

Neal Norwitz7a5fc282006-05-15 06:48:14 +000028Extension Modules
29-----------------
30
31- On Win32, os.listdir now supports arbitrarily-long Unicode path names
32 (up to the system limit of 32K characters).
33
34- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
35 As a result, these functions now raise WindowsError instead of OSError.
36
37- Calling Tk_Init twice is refused if the first call failed as that
38 may deadlock.
39

41-------
42
Georg Brandl49c8f4c2006-05-15 19:30:35 +000043- Patch #1488881: add support for external file objects in bz2 compressed
44 tarfiles.
45
Neal Norwitz7a5fc282006-05-15 06:48:14 +000046- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
47 stdout arguments, making it possible to redirect input and output
48 for remote debugging.
49
50- Patch #1484695: Update the tarfile module to version 0.8. This fixes
51 a couple of issues, notably handling of long file names using the
52 GNU LONGNAME extension.
53
54- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
55 new flag when ``name`` is already the name of an option flag.
56
57- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
58 package.
59
60- Patch #1472854: make the rlcompleter.Completer class usable on non-
61 UNIX platforms.

86
87Core and builtins
88-----------------
89
Thomas Heller1b046642006-04-18 18:51:06 +000090- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
91 by converting these apis from macros into exported functions again:
92
93 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
94 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
95 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
96 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
97 PyRun_String Py_CompileString
98
Martin v. Löwis45294a92006-04-18 06:24:08 +000099- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
100
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000101- All uses of PyStructSequence_InitType have been changed to initialize
102 the type objects only once, even if the interpreter is initialized
103 multiple times.
104
Neal Norwitz61546162006-04-14 05:20:28 +0000105- Bug #1454485, array.array('u') could crash the interpreter. This was
106 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
107 to unicode when it didn't make sense. 'u#' now requires a unicode string.
108
109- Py_UNICODE is unsigned. It was always documented as unsigned, but
110 due to a bug had a signed value in previous versions.
111
Tim Peters3a5e8b12006-04-11 01:44:07 +0000112- Patch #837242: ``id()`` of any Python object always gives a positive
113 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
114 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000115 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000116 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000117
Tim Peters3a5e8b12006-04-11 01:44:07 +0000118 def __hash__(self):
119 return id(self) # WRONG
120
121 because a hash result must be a (short) Python int but it was always
122 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000123 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000124 was always usable as a hash value before this patch. That's no longer
125 necessarily so.
126
127- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000128 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000129 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000130 #1454844)
131
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000132- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
133 involving generators that have paused outside of any ``try`` or ``with``
134 blocks. (In 2.5a1, a paused generator that was part of a reference
135 cycle could not be garbage collected, regardless of whether it was
136 paused in a ``try`` or ``with`` block.)

139-----------------
140
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000141- Patch #1191065: Fix preprocessor problems on systems where recvfrom
142 is a macro.
143
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000144- Bug #1467952: os.listdir() now correctly raises an error if readdir()
145 fails with an error condition.
146
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000147- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
148
149- Bug #1117761: bsddb.*open() no longer raises an exception when using
150 the cachesize parameter.
151
152- Bug #1149413: bsddb.*open() no longer raises an exception when using
153 a temporary db (file=None) with the 'n' flag to truncate on open.
154
155- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
156 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000157
Armin Rigoa9017c32006-04-19 11:50:27 +0000158- Patch #1062014: AF_UNIX sockets under Linux have a special
159 abstract namespace that is now fully supported.
160
Anthony Baxter51bcb682006-04-05 14:51:42 +0000161Library
162-------
163
Tim Peters711bf302006-04-25 03:31:36 +0000164- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
165 a doctest to be skipped (the code is not run, and the expected output
166 or exception is ignored).
167
Nick Coghlanda2268f2006-04-24 04:37:15 +0000168- Fixed contextlib.nested to cope with exceptions being raised and
169 caught inside exit handlers.
170
Greg Wardab05edc2006-04-23 03:47:58 +0000171- Updated optparse module to Optik 1.5.1 (allow numeric constants in
172 hex, octal, or binary; add ``append_const`` action; keep going if
173 gettext cannot be imported; added ``OptionParser.destroy()`` method;
174 added ``epilog`` for better help generation).
175
Tim Peters21fbd572006-04-21 21:18:10 +0000176- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
177 called from a thread spawned as a side effect of importing a module.
178
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000179- The pydoc module now supports documenting packages contained in
180 .zip or .egg files.
181
182- The pkgutil module now has several new utility functions, such
183 as ``walk_packages()`` to support working with packages that are either
184 in the filesystem or zip files.
185
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000186- The mailbox module can now modify and delete messages from
187 mailboxes, in addition to simply reading them. Thanks to Gregory
188 K. Johnson for writing the code, and to the 2005 Google Summer of
189 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000190
Tim Petersc7605f22006-04-17 21:12:33 +0000191- The ``__del__`` method of class ``local`` in module ``_threading_local``
192 returned before accomplishing any of its intended cleanup.
193
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000194- Patch #790710: Add breakpoint command lists in pdb.
195
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000196- Patch #1063914: Add Tkinter.Misc.clipboard_get().
197
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000198- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
199
Anthony Baxtere29002c2006-04-12 12:07:31 +0000200- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
201 Windows. Bug #1469163.
202
Phillip J. Eby47032112006-04-11 01:07:43 +0000203- The warnings, linecache, inspect, traceback, site, and doctest modules
204 were updated to work correctly with modules imported from zipfiles or
205 via other PEP 302 __loader__ objects.
206
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000207- Patch #1467770: Reduce usage of subprocess._active to processes which
208 the application hasn't waited on.
209
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000210- Patch #1462222: Fix Tix.Grid.
211
Neal Norwitza31bf182006-04-09 03:35:43 +0000212- Fix exception when doing glob.glob('anything*/')
213
Skip Montanaro262fb922006-04-21 02:31:07 +0000214- The pstats.Stats class accepts an optional stream keyword argument to
215 direct output to an alternate file-like object.
216
Anthony Baxter51bcb682006-04-05 14:51:42 +0000217Build
218-----
219
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000220- The Makefile now has a reindent target, which runs reindent.py on
221 the library.
222
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000223- Patch #1470875: Building Python with MS Free Compiler
224
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000225- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000226
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000227- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
228 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000229 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000230 CXX from --with-cxx-main, see description in README.
231
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000232- Patch #1429775: Link extension modules with the shared libpython.
233
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000234- Fixed a libffi build problem on MIPS systems.
235
Tim Peters8931ff12006-05-13 23:28:20 +0000236- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
237 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
238 and "%zu" for unsigned integers of type ``size_t``.

241-----
242
Nick Coghlanda2268f2006-04-24 04:37:15 +0000243- test_contextlib now checks contextlib.nested can cope with exceptions
244 being raised and caught inside exit handlers.
245
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000246- test_cmd_line now checks operation of the -m and -c command switches
247
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000248- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
249 it separately and by hand. It also wasn't cleaning up its changes to
250 the current Decimal context.
251
Thomas Woutersabd08882006-04-26 15:53:30 +0000252- regrtest.py now has a -M option to run tests that test the new limits of
253 containers, on 64-bit architectures. Running these tests is only sensible
254 on 64-bit machines with more than two gigabytes of memory. The argument
255 passed is the maximum amount of memory for the tests to use.

264-------------
265
Tim Petersb06d28c2006-05-12 01:57:59 +0000266- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
267
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000268- PEP 343: Added Context Types section to the library reference
269 and attempted to bring other PEP 343 related documentation into
270 line with the implementation and/or python-dev discussions.
271
Tim Peters8dc73d22006-04-24 02:03:16 +0000272- Bug #1337990: clarified that ``doctest`` does not support examples
273 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000279*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000280
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000281Core and builtins
282-----------------
283
Nick Coghlan43832302006-04-23 17:04:07 +0000284- PEP 338: -m command line switch now delegates to runpy.run_module
285 allowing it to support modules in packages and zipfiles
286
Martin v. Löwisc661b882006-04-20 04:54:23 +0000287- On Windows, .DLL is not an accepted file name extension for
288 extension modules anymore; extensions are only found if they
289 end in .PYD.
290
Martin v. Löwisea62d252006-04-03 10:56:49 +0000291- Bug #1421664: sys.stderr.encoding is now set to the same value as
292 sys.stdout.encoding.
293
Neal Norwitz92e212f2006-04-03 04:48:37 +0000294- __import__ accepts keyword arguments.
295
Georg Brandlccadf842006-03-31 18:54:53 +0000296- Patch #1460496: round() now accepts keyword arguments.
297
Anthony Baxter262c00a2006-03-30 10:53:17 +0000298- Fixed bug #1459029 - unicode reprs were double-escaped.
299
Hye-Shik Changd478f342006-03-23 12:32:36 +0000300- Patch #1396919: The system scope threads are reenabled on FreeBSD
301 5.4 and later versions.
302
Neal Norwitze98ccf62006-03-23 05:39:47 +0000303- Bug #1115379: Compiling a Unicode string with an encoding declaration
304 now gives a SyntaxError.
305
Georg Brandlabd1ff82006-03-18 07:59:59 +0000306- Previously, Python code had no easy way to access the contents of a
307 cell object. Now, a ``cell_contents`` attribute has been added
308 (closes patch #1170323).
309
Tim Peterscf79aac2006-03-16 01:14:46 +0000310- Patch #1123430: Python's small-object allocator now returns an arena to
311 the system ``free()`` when all memory within an arena becomes unused
312 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
313 freed. Some applications will see a drop in virtual memory size now,
314 especially long-running applications that, from time to time, temporarily
315 use a large number of small objects. Note that when Python returns an
316 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000317 platform C library will in turn return that memory to the operating system.
318 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000319 appears to be effective at least on Microsoft C and gcc-based systems.
320 Thanks to Evan Jones for hard work and patience.
321
Georg Brandl533ff6f2006-03-08 18:09:27 +0000322- Patch #1434038: property() now uses the getter's docstring if there is
323 no "doc" argument given. This makes it possible to legitimately use
324 property() as a decorator to produce a read-only property.
325
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000326- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
327 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
328 of requiring an int or long in slicing and a few other contexts, enabling
329 other objects (e.g. Numeric Python's integers) to be used as slice indices.
330
Neal Norwitz995acdf2006-03-07 05:01:00 +0000331- Fixed various bugs reported by Coverity's Prevent tool.
332
Brett Cannonbf364092006-03-01 04:25:17 +0000333- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
334 new exception base class, BaseException, which has a new message attribute.
335 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
336 Raising a string exception now raises a DeprecationWarning.
337
Thomas Woutersfb609f42006-02-28 16:37:25 +0000338- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
339 explicitly relative, using 'from .module import name' to mean 'from the same
340 package as this module is in. Imports without dots still default to the
341 old relative-then-absolute, unless 'from __future__ import
342 absolute_import' is used.
343
Brett Cannona7446e32006-02-27 23:39:10 +0000344- Properly check if 'warnings' raises an exception (usually when a filter set
345 to "error" is triggered) when raising a warning for raising string
346 exceptions.
347
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000348- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000349 The name was removed from Include/code.h.
350
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000351- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000352
Guido van Rossum1968ad32006-02-25 22:38:04 +0000353- Patch 1433928:
354 - The copy module now "copies" function objects (as atomic objects).
355 - dict.__getitem__ now looks for a __missing__ hook before raising
356 KeyError.
357
Tim Peters84ef21c2006-02-28 20:39:06 +0000358- PEP 343: with statement implemented. Needs ``from __future__ import
359 with_statement``. Use of 'with' as a variable will generate a warning.
360 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000361 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000362 The following objects have __context__ methods:
363 - The built-in file type.
364 - The thread.LockType type.
365 - The following types defined by the threading module:
366 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
367 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000368
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000369- Fix the encodings package codec search function to only search
370 inside its own package. Fixes problem reported in patch #1433198.
371
372 Note: Codec packages should implement and register their own
373 codec search function. PEP 100 has the details.
374
Martin v. Löwis18e16552006-02-15 17:27:45 +0000375- PEP 353: Using ssize_t as the index type.
376
Neal Norwitzfc76d632006-01-10 06:03:13 +0000377- Patch #1400181, fix unicode string formatting to not use the locale.
378 This is how string objects work. u'%f' could use , instead of .
379 for the decimal point. Now both strings and unicode always use periods.
380
Neal Norwitz671b9e32006-01-09 07:07:12 +0000381- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
382 configure would break checking curses.h.
383
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000384- Bug #959576: The pwd module is now builtin. This allows Python to be
385 built on UNIX platforms without $HOME set.
386
Neal Norwitzc10978f2005-12-19 06:07:16 +0000387- Bug #1072182, fix some potential problems if characters are signed.
388
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000389- Bug #889500, fix line number on SyntaxWarning for global declarations.
390
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000391- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
392
Neal Norwitze7214a12005-12-18 05:03:17 +0000393- Support for converting hex strings to floats no longer works.
394 This was not portable. float('0x3') now raises a ValueError.
395
Barry Warsaw2a38a862005-12-18 01:27:35 +0000396- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000397 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000398 is now displayed in interactive prompt banner.
399
Georg Brandlfa166682005-12-17 21:45:17 +0000400- Implementation of PEP 341 - Unification of try/except and try/finally.
401 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000402 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000403
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000404- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
405 now encodes backslash correctly.
406
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000407- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
408
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000409- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000410 and long longs.
411
Neal Norwitz67715f02005-11-09 06:59:35 +0000412- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000413 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000414 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000415
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000416- Replaced most Unicode charmap codecs with new ones using the
417 new Unicode translate string feature in the builtin charmap
418 codec; the codecs were created from the mapping tables available
419 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
420 encodings now include a mapping for the Apple logo)
421
Tim Peterse3547fd2005-12-16 23:13:57 +0000422- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000423
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000424- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000425
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000426- A new AST parser implementation was completed. The abstract
427 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000428 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000429
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000430- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000431 The following code now raises a SyntaxError: foo(a = i for i in range(10))
432
Neal Norwitz708e51a2005-10-03 04:48:15 +0000433- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
434
Neal Norwitz11bd1192005-10-03 00:54:56 +0000435- SF Bug #887946: fix segfault when redirecting stdin from a directory.
436 Provide a warning when a directory is passed on the command line.
437
Neal Norwitz40d37812005-10-02 01:48:49 +0000438- Fix segfault with invalid coding.
439
440- SF bug #772896: unknown encoding results in MemoryError.
441
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000442- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000443 supported a __len__() method which evaluated to False when the iterator
444 was empty.
445
Guido van Rossum630db602005-09-20 18:49:54 +0000446- On 64-bit platforms, when __len__() returns a value that cannot be
447 represented as a C int, raise OverflowError.
448
Skip Montanarof8948ca2005-09-19 03:54:46 +0000449- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000450 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000451
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000452- SF bug #893549: parsing keyword arguments was broken with a few format
453 codes.
454
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000455- Changes donated by Elemental Security to make it work on AIX 5.3
456 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
457 bug #105470: test_pwd fails on 64bit system (Opteron).
458
Guido van Rossum539c6622005-09-14 17:49:54 +0000459- Changes donated by Elemental Security to make it work on HP-UX 11 on
460 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
461
Georg Brandl4550b8d2005-08-26 06:43:52 +0000462- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000463 (fixes bug #1119418).
464
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000465- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
466
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000467- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
468 exceptions that cause a function to exit.
469
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000470- The implementation of set() and frozenset() was revised to use its
471 own internal data structure. Memory consumption is reduced by 1/3
472 and there are modest speed-ups as well. The API is unchanged.
473
Tim Petersde7990b2005-07-17 23:45:23 +0000474- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
475
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000476- SF bug #1229429: PyObject_CallMethod failed to decrement some
477 reference counts in some error exit cases.
478
Tim Petersecc6e6a2005-07-10 22:30:55 +0000479- SF bug #1185883: Python's small-object memory allocator took over
480 a block managed by the platform C library whenever a realloc specified
481 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000482 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000483 portable way to copy data from the C-managed block into Python's
484 small-object space without risking a memory fault. Python's small-object
485 realloc now leaves such blocks under the control of the platform C
486 realloc.
487
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000488- SF bug #1232517: An overflow error was not detected properly when
489 attempting to convert a large float to an int in os.utime().
490
Raymond Hettinger3296e692005-06-29 23:29:56 +0000491- SF bug #1224347: hex longs now print with lowercase letters just
492 like their int counterparts.
493
Michael W. Hudson188d4362005-06-20 16:52:57 +0000494- SF bug #1163563: the original fix for bug #1010677 ("thread Module
495 Breaks PyGILState_Ensure()") broke badly in the case of multiple
496 interpreter states; back out that fix and do a better job (see
497 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
498 for a longer write-up of the problem).
499
Michael W. Hudsondf888462005-06-03 14:41:55 +0000500- SF patch #1180995: marshal now uses a binary format by default when
501 serializing floats.
502
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000503- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
504 the routines that promise to produce IEEE 754 binary representations
505 of floats now simply copy bytes around.
506
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000507- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
508 278.
509
Brett Cannonc3647ac2005-04-26 03:45:26 +0000510- patch #1109424: int, long, float, complex, and unicode now check for the
511 proper magic slot for type conversions when subclassed. Previously the
512 magic slot was ignored during conversion. Semantics now match the way
513 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000514 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000515 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000516 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000517
Barry Warsawc8d907c2005-04-19 23:43:40 +0000518- Descriptors defined in C with a PyGetSetDef structure, where the setter is
519 NULL, now raise an AttributeError when attempting to set or delete the
520 attribute. Previously a TypeError was raised, but this was inconsistent
521 with the equivalent pure-Python implementation.
522
Michael W. Hudson774479c2005-04-18 08:46:17 +0000523- It is now safe to call PyGILState_Release() before
524 PyEval_InitThreads() (note that if there is reason to believe there
525 are multiple threads around you still must call PyEval_InitThreads()
526 before using the Python API; this fix is for extension modules that
527 have no way of knowing if Python is multi-threaded yet).
528
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000529- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
530 disabled caused a crash.
531
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000532- Bug #1165306: instancemethod_new allowed the creation of a method
533 with im_class == im_self == NULL, which caused a crash when called.
534
Tim Petersecc6e6a2005-07-10 22:30:55 +0000535- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000536 fixes the crash seen in bug #1165761
537
Raymond Hettinger96229b12005-03-11 06:49:40 +0000538- Added two new builtins, any() and all().
539
Brett Cannon409d8f22005-03-05 06:47:57 +0000540- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000541 (e.g., ``class C(): pass`` is no longer a syntax error).
542 Patch #1176012 added support to the 'parser' module and 'compiler' package
543 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000544
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000545- Patch #1115086: Support PY_LONGLONG in structmember.
546
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000547- Bug #1155938: new style classes did not check that __init__() was
548 returning None.
549
Tim Petersecc6e6a2005-07-10 22:30:55 +0000550- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000551 ('\') with a specific error message.
552
Martin v. Löwisff232d72005-03-03 09:24:38 +0000553- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
554
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000555- Bug #1124295: the __name__ attribute of file objects was
556 inadvertently made inaccessible in restricted mode.
557
Tim Petersecc6e6a2005-07-10 22:30:55 +0000558- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000559 an ferror() call.
560
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000561- min() and max() now support key= arguments with the same meaning as in
562 list.sort().
563
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000564- The peephole optimizer now performs simple constant folding in expressions:
565 (2+3) --> (5).
566
Raymond Hettingera422c342005-01-11 03:03:27 +0000567- set and frozenset objects can now be marshalled. SF #1098985.
568
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000569- Bug #1077106: Poor argument checking could cause memory corruption
570 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000571
Jeremy Hyltonab630502005-02-04 18:44:06 +0000572- The parser did not complain about future statements in illegal
573 positions. It once again reports a syntax error if a future
574 statement occurs after anything other than a doc string.
575
Neil Schemenauercf52c072005-08-12 17:34:58 +0000576- Change the %s format specifier for str objects so that it returns a
577 unicode instance if the argument is not an instance of basestring and
578 calling __str__ on the argument returns a unicode instance.
579
Tim Petersf4e69282006-02-27 17:15:31 +0000580- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
581 current thread state when the auto-GIL-state machinery knows about
582 it (since the thread state is being deleted, continuing to remember it
583 can't help, but can hurt if another thread happens to get created with
584 the same thread id).
585
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000586Extension Modules
587-----------------
588
Georg Brandl43f08a82006-03-31 18:01:16 +0000589- Patch #1380952: fix SSL objects timing out on consecutive read()s
590
Neal Norwitz05a45592006-03-20 06:30:08 +0000591- Patch #1309579: wait3 and wait4 were added to the posix module.
592
Anthony Baxterfa869072006-03-20 05:21:58 +0000593- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
594 In addition, the existing ulaw code was updated.
595
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000596- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000597 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000598
Neal Norwitz10be10c2006-03-16 06:50:13 +0000599- Everything under lib-old was removed. This includes the following modules:
600 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000601 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000602 util, whatsound, whrandom, zmod
603
604- The following modules were removed: regsub, reconvert, regex, regex_syntax.

774-------
775
Nick Coghlan43832302006-04-23 17:04:07 +0000776- PEP 338: new module runpy defines a run_module function to support
777 executing modules which provide access to source code or a code object
778 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000791 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000792 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000793 module will not be built.
794
Tim Petersc17976e2006-04-01 00:26:53 +0000795- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
796 aren't officially supported here, and trying to use them will probably
797 raise an exception some day. But dicts have been allowed, and "mostly
798 worked", so support for them won't go away without warning.
799
Georg Brandl338ef7d2006-03-31 18:42:16 +0000800- Bug #1445068: getpass.getpass() can now be given an explicit stream

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000819- email 4.0 package now integrated. This is largely the same as the email 3.0
820 package that was included in Python 2.3, except that PEP 8 module names are
821 now used (e.g. mail.message instead of email.Message). The MIME classes
822 have been moved to a subpackage (e.g. email.mime.text instead of
823 email.MIMEText). The old names are still supported for now. Several
824 deprecated Message methods have been removed and lots of bugs have been
825 fixed. More details can be found in the email package documentation.
826

828 (a subclass of tuple) that provides incremental decoders and encoders
829 (a way to use stateful codecs without the stream API). Python functions
830 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
831 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
832 have been added.

835 a ValueError instead of a StopIteration now (like file and cString.String do).
836 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
837 called before (like file and StringIO.StringIO do).

907 LoadError as documented, instead of IOError. For compatibility,
908 LoadError subclasses IOError.
909
Brett Cannon3cbd0382005-12-16 22:49:23 +0000910- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000911 SHA1, 224, 256, 384, and 512. Note that recent developments make the
912 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
913 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
914 Ronald L. Rivest offered this advice for Python:
915
916 "The consensus of researchers in this area (at least as
917 expressed at the NIST Hash Function Workshop 10/31/05),
918 is that SHA-256 is a good choice for the time being, but
919 that research should continue, and other alternatives may
920 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000921
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000922- Added a subset of Fredrik Lundh's ElementTree package. Available

975 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000976 correct line numbers for decoding errors in source code.

1015 Bug #1224621.
1016
Raymond Hettinger68c04532005-06-10 11:05:19 +00001017- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001018 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001019 the generate_tokens() function now accepts a callable argument that
1020 terminates by raising StopIteration.
1021
Georg Brandl9166e1a2005-06-04 09:20:03 +00001022- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1037
Raymond Hettinger267b8682005-03-27 10:47:39 +00001038- decimal operator and comparison methods now return NotImplemented
1039 instead of raising a TypeError when interacting with other types. This
1040 allows other classes to implement __radd__ style methods and have them
1041 work as expected.
1042
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001043- Bug #1163325: Decimal infinities failed to hash. Attempting to
1044 hash a NaN raised an InvalidOperation instead of a TypeError.
1045
Tim Petersecc6e6a2005-07-10 22:30:55 +00001046- Patch #918101: Add tarfile open mode r|* for auto-detection of the

Guido van Rossumd0641422005-02-03 15:01:24 +00001081- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1082 disables recursive traversal through instance attributes, which can
1083 be exploited in various ways.
1084
Tim Peterse3547fd2005-12-16 23:13:57 +00001085- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001086 flags on the HTTP listening socket.
1087
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001088- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1089 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1090

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001096- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1097
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001098- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1099
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001100- Enhancements to the csv module:
1101
1102 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001103 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001104 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001105 + Dialect parameter parsing has been re-implemented to improve error
1106 reporting.
1107 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1108 dictates.
1109 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001110 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001111 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001112 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1113 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001114 + reader now allows \r characters to be quoted (previously it only allowed
1115 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001116 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001117 + Dialect classes passed to the module are no longer instantiated by
1118 the module before being parsed (the former validation scheme required
1119 this, but the mechanism was unreliable).
1120 + The dialect registry now contains instances of the internal
1121 C-coded dialect type, rather than references to python objects.
1122 + the internal c-coded dialect type is now immutable.
1123 + register_dialect now accepts the same keyword dialect specifications
1124 as the reader and writer, allowing the user to register dialects
1125 without first creating a dialect class.
1126 + a configurable limit to the size of parsed fields has been added -
1127 previously, an unmatched quote character could result in the entire
1128 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001129 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001130 the parser field size limit (returning the former limit). The initial
1131 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001132 + A line_num attribute has been added to the reader object, which tracks
1133 the number of lines read from the source iterator. This is not
1134 the same as the number of records returned, as records can span
1135 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001136 + reader and writer objects were not being registered with the cyclic-GC.
1137 This has been fixed.
1138
Brett Cannone6539c42005-01-08 02:43:53 +00001139- _DummyThread objects in the threading module now delete self.__block that is
1140 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1141 lock primitives tend to be limited in number and thus should not be wasted on
1142 a _DummyThread object. Fixes bug #1089632.
1143
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001144- The imghdr module now detects Exif files.
1145
Raymond Hettinger6065d322004-12-20 23:51:53 +00001146- StringIO.truncate() now correctly adjusts the size attribute.
1147 (Bug #951915).
1148
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001149- locale.py now uses an updated locale alias table (built using
1150 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1151 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001152 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001153
Raymond Hettinger3557f422004-12-07 12:02:02 +00001154- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1155
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001156- the pickle module no longer accepts the deprecated None option in the
1157 args tuple returned by __reduce__().
1158
Brett Cannon84667c02004-12-07 03:25:18 +00001159- optparse now optionally imports gettext. This allows its use in setup.py.
1160
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001161- the pickle module no longer uses the deprecated bin parameter.
1162
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001163- the shelve module no longer uses the deprecated binary parameter.
1164

1166
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001167- the filecmp module no longer uses the deprecated use_statcache argument.
1168
Raymond Hettinger664347b2004-12-04 21:21:53 +00001169- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1170 extended or overridden by subclasses. Formerly, the subclassed method would
1171 be ignored by the rest of the module. (Bug #1078905).
1172
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001173- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001174 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001175
Walter Dörwald36733692004-12-22 12:50:50 +00001176- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1177 once when a size argument is given. This prevents a buffer overflow in the
1178 tokenizer with very long source lines.
1179
Barry Warsaw538561e2006-01-01 21:48:54 +00001180- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1181 immediately after creating the object, without any intervening
1182 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001183
Skip Montanaro05885812005-01-16 20:48:27 +00001184- The reconvert.quote function can now emit triple-quoted strings. The
1185 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001186
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001187- ``UserString.MutableString`` now supports negative indices in
1188 ``__setitem__`` and ``__delitem__``
1189
Greg Ward40407942005-03-05 02:53:17 +00001190- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1191 correctly.
1192
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001193- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1194 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1195 character even if the user has passed a size parameter to get a proper
1196 line ending. Remove the special handling of a "\r\n" that has been split
1197 between two lines.
1198
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001199- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1200 about illegal code points. The codec now supports PEP 293 style error
1201 handlers.
1202
Walter Dörwald78a78b02005-09-01 12:04:29 +00001203- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001204 from the input stream, so that the output is a byte string in the correct
1205 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001206
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001207- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1208 considering it exactly like a '*'.
1209
Walter Dörwald007f8df2005-10-09 19:42:27 +00001210- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1211 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001212
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001213- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1214
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001215- Patch #1413711: Certain patterns of differences were making difflib
1216 touch the recursion limit.
1217
Walter Dörwald58917a62006-03-31 15:26:22 +00001218- Bug #947906: An object oriented interface has been added to the calendar
1219 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001220 called as a script (e.g. via ``python -mcalendar``). Localized month and
1221 weekday names can be ouput (even if an exotic encoding is used) using
1222 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001223
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001224Build
1225-----
1226
Neal Norwitz602d3392006-03-31 08:21:40 +00001227- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1228 by using -mieee gcc option.
1229

1231
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001232- Build support for Win64-AMD64 was added.
1233
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001234- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1235
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001236- Patch #881820: look for openpty and forkpty also in libbsd.
1237
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001238- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1239 The zlib module is now builtin on Windows.
1240
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001241- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1242
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001243- Bug #1189330: configure did not correctly determine the necessary
1244 value of LINKCC if python was built with GCC 4.0.
1245
Trent Mick8321b422005-07-26 02:29:21 +00001246- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1247 vulnerability in zlib 1.2.1 and 1.2.2.
1248
Brett Cannon08cd5982005-04-24 22:26:38 +00001249- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1250 flags that change binary compatibility. Changes were also made to
1251 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001252 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001253
Bob Ippolitoed233462005-03-29 13:47:59 +00001254- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1255 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1256 no longer exists). This configure patch makes things right.
1257
Martin v. Löwise2713be2005-03-08 15:03:08 +00001258- Bug #1158607: Build with --disable-unicode again.
1259
Brett Cannon46d96232005-02-16 00:07:19 +00001260- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1261 defined. Discovered as a result of not being able to build on OS X.
1262
Brett Cannon516592f2004-12-07 00:42:59 +00001263- setup.py now uses the directories specified in LDFLAGS using the -L option
1264 and in CPPFLAGS using the -I option for adding library and include
1265 directories, respectively, for compiling extension modules against. This has
1266 led to the core being compiled using the values in CPPFLAGS. It also removes
1267 the need for the special-casing of both DarwinPorts and Fink for darwin since
1268 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1269 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1270 Fink, ``-I/opt/local/include`` for DarwinPorts).
1271
Brett Cannon43802422005-02-10 20:48:03 +00001272- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1273 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1274 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1275 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001277C API
1278-----
1279
Tim Petersc9d78aa2006-03-26 23:27:58 +00001280- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1281 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1282 is obtained via the ``PyObject_`` family, it must be released via the
1283 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1284 always been officially true, but when Python's small-object allocator was
1285 introduced, an attempt was made to cater to a few extension modules
1286 discovered at the time that obtained memory via ``PyObject_New`` but
1287 released it via ``PyMem_DEL``. It's years later, and if such code still
1288 exists it will fail now (probably with segfaults, but calling wrong
1289 low-level memory management functions can yield many symptoms).
1290
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001291- Added a C API for set and frozenset objects.
1292

1294
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001295- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1296 mapping argument now. This string is used as a mapping table. Byte values
1297 greater than the length of the string and 0xFFFE are treated as undefined
1298 mappings.
