13-----------------
14
Neal Norwitz373f0a72006-05-15 07:04:36 +000015- Bug #1487966: Fix SystemError with conditional expression in assignment
16
Martin v. Löwis879768d2006-05-11 13:28:43 +000017- WindowsError now has two error code attributes: errno, which carries
18 the error values from errno.h, and winerror, which carries the error
19 values from winerror.h. Previous versions put the winerror.h values
20 (from GetLastError()) into the errno attribute.
21
Martin v. Löwis77736712006-05-04 05:51:03 +000022- Patch #1475845: Raise IndentationError for unexpected indent.
23
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000024- Patch #1479181: split open() and file() from being aliases for each other.
25
Neal Norwitz7a5fc282006-05-15 06:48:14 +000026Extension Modules
27-----------------
28
29- On Win32, os.listdir now supports arbitrarily-long Unicode path names
30 (up to the system limit of 32K characters).
31
32- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
33 As a result, these functions now raise WindowsError instead of OSError.
34
35- Calling Tk_Init twice is refused if the first call failed as that
36 may deadlock.
37
38Library
39-------
40
41- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
42 stdout arguments, making it possible to redirect input and output
43 for remote debugging.
44
45- Patch #1484695: Update the tarfile module to version 0.8. This fixes
46 a couple of issues, notably handling of long file names using the
47 GNU LONGNAME extension.
48
49- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
50 new flag when ``name`` is already the name of an option flag.
51
52- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
53 package.
54
55- Patch #1472854: make the rlcompleter.Completer class usable on non-
56 UNIX platforms.
57
58- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

77What's New in Python 2.5 alpha 2?
78=================================
79
80*Release date: 27-APR-2006*
81
82Core and builtins
83-----------------
84
Thomas Heller1b046642006-04-18 18:51:06 +000085- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
86 by converting these apis from macros into exported functions again:
87
88 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
89 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
90 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
91 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
92 PyRun_String Py_CompileString
93
Martin v. Löwis45294a92006-04-18 06:24:08 +000094- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
95
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000096- All uses of PyStructSequence_InitType have been changed to initialize
97 the type objects only once, even if the interpreter is initialized
98 multiple times.
99
Neal Norwitz61546162006-04-14 05:20:28 +0000100- Bug #1454485, array.array('u') could crash the interpreter. This was
101 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
102 to unicode when it didn't make sense. 'u#' now requires a unicode string.
103
104- Py_UNICODE is unsigned. It was always documented as unsigned, but
105 due to a bug had a signed value in previous versions.
106
Tim Peters3a5e8b12006-04-11 01:44:07 +0000107- Patch #837242: ``id()`` of any Python object always gives a positive
108 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
109 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000110 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000111 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000112
Tim Peters3a5e8b12006-04-11 01:44:07 +0000113 def __hash__(self):
114 return id(self) # WRONG
115
116 because a hash result must be a (short) Python int but it was always
117 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000118 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000119 was always usable as a hash value before this patch. That's no longer
120 necessarily so.
121
122- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000123 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000124 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000125 #1454844)
126
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000127- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
128 involving generators that have paused outside of any ``try`` or ``with``
129 blocks. (In 2.5a1, a paused generator that was part of a reference
130 cycle could not be garbage collected, regardless of whether it was
131 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000133Extension Modules
134-----------------
135
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000136- Patch #1191065: Fix preprocessor problems on systems where recvfrom
137 is a macro.
138
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000139- Bug #1467952: os.listdir() now correctly raises an error if readdir()
140 fails with an error condition.
141
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000142- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
143
144- Bug #1117761: bsddb.*open() no longer raises an exception when using
145 the cachesize parameter.
146
147- Bug #1149413: bsddb.*open() no longer raises an exception when using
148 a temporary db (file=None) with the 'n' flag to truncate on open.
149
150- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
151 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000152
Armin Rigoa9017c32006-04-19 11:50:27 +0000153- Patch #1062014: AF_UNIX sockets under Linux have a special
154 abstract namespace that is now fully supported.
155
Anthony Baxter51bcb682006-04-05 14:51:42 +0000156Library
157-------
158
Tim Peters711bf302006-04-25 03:31:36 +0000159- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
160 a doctest to be skipped (the code is not run, and the expected output
161 or exception is ignored).
162
Nick Coghlanda2268f2006-04-24 04:37:15 +0000163- Fixed contextlib.nested to cope with exceptions being raised and
164 caught inside exit handlers.
165
Greg Wardab05edc2006-04-23 03:47:58 +0000166- Updated optparse module to Optik 1.5.1 (allow numeric constants in
167 hex, octal, or binary; add ``append_const`` action; keep going if
168 gettext cannot be imported; added ``OptionParser.destroy()`` method;
169 added ``epilog`` for better help generation).
170
Tim Peters21fbd572006-04-21 21:18:10 +0000171- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
172 called from a thread spawned as a side effect of importing a module.
173
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000174- The pydoc module now supports documenting packages contained in
175 .zip or .egg files.
176
177- The pkgutil module now has several new utility functions, such
178 as ``walk_packages()`` to support working with packages that are either
179 in the filesystem or zip files.
180
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000181- The mailbox module can now modify and delete messages from
182 mailboxes, in addition to simply reading them. Thanks to Gregory
183 K. Johnson for writing the code, and to the 2005 Google Summer of
184 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000185
Tim Petersc7605f22006-04-17 21:12:33 +0000186- The ``__del__`` method of class ``local`` in module ``_threading_local``
187 returned before accomplishing any of its intended cleanup.
188
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000189- Patch #790710: Add breakpoint command lists in pdb.
190
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000191- Patch #1063914: Add Tkinter.Misc.clipboard_get().
192
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000193- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
194
Anthony Baxtere29002c2006-04-12 12:07:31 +0000195- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
196 Windows. Bug #1469163.
197
Phillip J. Eby47032112006-04-11 01:07:43 +0000198- The warnings, linecache, inspect, traceback, site, and doctest modules
199 were updated to work correctly with modules imported from zipfiles or
200 via other PEP 302 __loader__ objects.
201
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000202- Patch #1467770: Reduce usage of subprocess._active to processes which
203 the application hasn't waited on.
204
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000205- Patch #1462222: Fix Tix.Grid.
206
Neal Norwitza31bf182006-04-09 03:35:43 +0000207- Fix exception when doing glob.glob('anything*/')
208
Skip Montanaro262fb922006-04-21 02:31:07 +0000209- The pstats.Stats class accepts an optional stream keyword argument to
210 direct output to an alternate file-like object.
211

214
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000215- The Makefile now has a reindent target, which runs reindent.py on
216 the library.
217
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000218- Patch #1470875: Building Python with MS Free Compiler
219
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000220- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000221
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000222- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
223 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000224 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000225 CXX from --with-cxx-main, see description in README.
226
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000227- Patch #1429775: Link extension modules with the shared libpython.
228
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000229- Fixed a libffi build problem on MIPS systems.
230
Tim Peters8931ff12006-05-13 23:28:20 +0000231- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
232 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
233 and "%zu" for unsigned integers of type ``size_t``.

237
Nick Coghlanda2268f2006-04-24 04:37:15 +0000238- test_contextlib now checks contextlib.nested can cope with exceptions
239 being raised and caught inside exit handlers.
240
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000241- test_cmd_line now checks operation of the -m and -c command switches
242
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000243- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
244 it separately and by hand. It also wasn't cleaning up its changes to
245 the current Decimal context.
246
Thomas Woutersabd08882006-04-26 15:53:30 +0000247- regrtest.py now has a -M option to run tests that test the new limits of
248 containers, on 64-bit architectures. Running these tests is only sensible
249 on 64-bit machines with more than two gigabytes of memory. The argument
250 passed is the maximum amount of memory for the tests to use.

259-------------
260
Tim Petersb06d28c2006-05-12 01:57:59 +0000261- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
262
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000263- PEP 343: Added Context Types section to the library reference
264 and attempted to bring other PEP 343 related documentation into
265 line with the implementation and/or python-dev discussions.
266
Tim Peters8dc73d22006-04-24 02:03:16 +0000267- Bug #1337990: clarified that ``doctest`` does not support examples
268 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000271What's New in Python 2.5 alpha 1?
272=================================
273
Anthony Baxterebed3f62006-04-03 15:03:44 +0000274*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000275
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000276Core and builtins
277-----------------
278
Nick Coghlan43832302006-04-23 17:04:07 +0000279- PEP 338: -m command line switch now delegates to runpy.run_module
280 allowing it to support modules in packages and zipfiles
281
Martin v. Löwisc661b882006-04-20 04:54:23 +0000282- On Windows, .DLL is not an accepted file name extension for
283 extension modules anymore; extensions are only found if they
284 end in .PYD.
285
Martin v. Löwisea62d252006-04-03 10:56:49 +0000286- Bug #1421664: sys.stderr.encoding is now set to the same value as
287 sys.stdout.encoding.
288
Neal Norwitz92e212f2006-04-03 04:48:37 +0000289- __import__ accepts keyword arguments.
290
Georg Brandlccadf842006-03-31 18:54:53 +0000291- Patch #1460496: round() now accepts keyword arguments.
292
Anthony Baxter262c00a2006-03-30 10:53:17 +0000293- Fixed bug #1459029 - unicode reprs were double-escaped.
294
Hye-Shik Changd478f342006-03-23 12:32:36 +0000295- Patch #1396919: The system scope threads are reenabled on FreeBSD
296 5.4 and later versions.
297
Neal Norwitze98ccf62006-03-23 05:39:47 +0000298- Bug #1115379: Compiling a Unicode string with an encoding declaration
299 now gives a SyntaxError.
300
Georg Brandlabd1ff82006-03-18 07:59:59 +0000301- Previously, Python code had no easy way to access the contents of a
302 cell object. Now, a ``cell_contents`` attribute has been added
303 (closes patch #1170323).
304
Tim Peterscf79aac2006-03-16 01:14:46 +0000305- Patch #1123430: Python's small-object allocator now returns an arena to
306 the system ``free()`` when all memory within an arena becomes unused
307 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
308 freed. Some applications will see a drop in virtual memory size now,
309 especially long-running applications that, from time to time, temporarily
310 use a large number of small objects. Note that when Python returns an
311 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000312 platform C library will in turn return that memory to the operating system.
313 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000314 appears to be effective at least on Microsoft C and gcc-based systems.
315 Thanks to Evan Jones for hard work and patience.
316
Georg Brandl533ff6f2006-03-08 18:09:27 +0000317- Patch #1434038: property() now uses the getter's docstring if there is
318 no "doc" argument given. This makes it possible to legitimately use
319 property() as a decorator to produce a read-only property.
320
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000321- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
322 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
323 of requiring an int or long in slicing and a few other contexts, enabling
324 other objects (e.g. Numeric Python's integers) to be used as slice indices.
325
Neal Norwitz995acdf2006-03-07 05:01:00 +0000326- Fixed various bugs reported by Coverity's Prevent tool.
327
Brett Cannonbf364092006-03-01 04:25:17 +0000328- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
329 new exception base class, BaseException, which has a new message attribute.
330 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
331 Raising a string exception now raises a DeprecationWarning.
332
Thomas Woutersfb609f42006-02-28 16:37:25 +0000333- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
334 explicitly relative, using 'from .module import name' to mean 'from the same
335 package as this module is in. Imports without dots still default to the
336 old relative-then-absolute, unless 'from __future__ import
337 absolute_import' is used.
338
Brett Cannona7446e32006-02-27 23:39:10 +0000339- Properly check if 'warnings' raises an exception (usually when a filter set
340 to "error" is triggered) when raising a warning for raising string
341 exceptions.
342
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000343- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000344 The name was removed from Include/code.h.
345
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000346- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000347
Guido van Rossum1968ad32006-02-25 22:38:04 +0000348- Patch 1433928:
349 - The copy module now "copies" function objects (as atomic objects).
350 - dict.__getitem__ now looks for a __missing__ hook before raising
351 KeyError.
352
Tim Peters84ef21c2006-02-28 20:39:06 +0000353- PEP 343: with statement implemented. Needs ``from __future__ import
354 with_statement``. Use of 'with' as a variable will generate a warning.
355 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000356 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000357 The following objects have __context__ methods:
358 - The built-in file type.
359 - The thread.LockType type.
360 - The following types defined by the threading module:
361 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
362 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000363
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000364- Fix the encodings package codec search function to only search
365 inside its own package. Fixes problem reported in patch #1433198.
366
367 Note: Codec packages should implement and register their own
368 codec search function. PEP 100 has the details.
369
Martin v. Löwis18e16552006-02-15 17:27:45 +0000370- PEP 353: Using ssize_t as the index type.
371
Neal Norwitzfc76d632006-01-10 06:03:13 +0000372- Patch #1400181, fix unicode string formatting to not use the locale.
373 This is how string objects work. u'%f' could use , instead of .
374 for the decimal point. Now both strings and unicode always use periods.
375
Neal Norwitz671b9e32006-01-09 07:07:12 +0000376- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
377 configure would break checking curses.h.
378
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000379- Bug #959576: The pwd module is now builtin. This allows Python to be
380 built on UNIX platforms without $HOME set.
381
Neal Norwitzc10978f2005-12-19 06:07:16 +0000382- Bug #1072182, fix some potential problems if characters are signed.
383
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000384- Bug #889500, fix line number on SyntaxWarning for global declarations.
385
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000386- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
387
Neal Norwitze7214a12005-12-18 05:03:17 +0000388- Support for converting hex strings to floats no longer works.
389 This was not portable. float('0x3') now raises a ValueError.
390
Barry Warsaw2a38a862005-12-18 01:27:35 +0000391- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000392 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000393 is now displayed in interactive prompt banner.
394
Georg Brandlfa166682005-12-17 21:45:17 +0000395- Implementation of PEP 341 - Unification of try/except and try/finally.
396 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000397 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000398
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000399- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
400 now encodes backslash correctly.
401
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000402- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
403
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000404- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000405 and long longs.
406
Neal Norwitz67715f02005-11-09 06:59:35 +0000407- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000408 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000409 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000410
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000411- Replaced most Unicode charmap codecs with new ones using the
412 new Unicode translate string feature in the builtin charmap
413 codec; the codecs were created from the mapping tables available
414 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
415 encodings now include a mapping for the Apple logo)
416
Tim Peterse3547fd2005-12-16 23:13:57 +0000417- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000418
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000419- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000420
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000421- A new AST parser implementation was completed. The abstract
422 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000423 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000424
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000425- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000426 The following code now raises a SyntaxError: foo(a = i for i in range(10))
427
Neal Norwitz708e51a2005-10-03 04:48:15 +0000428- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
429
Neal Norwitz11bd1192005-10-03 00:54:56 +0000430- SF Bug #887946: fix segfault when redirecting stdin from a directory.
431 Provide a warning when a directory is passed on the command line.
432
Neal Norwitz40d37812005-10-02 01:48:49 +0000433- Fix segfault with invalid coding.
434
435- SF bug #772896: unknown encoding results in MemoryError.
436
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000437- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000438 supported a __len__() method which evaluated to False when the iterator
439 was empty.
440
Guido van Rossum630db602005-09-20 18:49:54 +0000441- On 64-bit platforms, when __len__() returns a value that cannot be
442 represented as a C int, raise OverflowError.
443
Skip Montanarof8948ca2005-09-19 03:54:46 +0000444- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000445 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000446
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000447- SF bug #893549: parsing keyword arguments was broken with a few format
448 codes.
449
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000450- Changes donated by Elemental Security to make it work on AIX 5.3
451 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
452 bug #105470: test_pwd fails on 64bit system (Opteron).
453
Guido van Rossum539c6622005-09-14 17:49:54 +0000454- Changes donated by Elemental Security to make it work on HP-UX 11 on
455 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
456
Georg Brandl4550b8d2005-08-26 06:43:52 +0000457- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000458 (fixes bug #1119418).
459
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000460- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
461
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000462- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
463 exceptions that cause a function to exit.
464
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000465- The implementation of set() and frozenset() was revised to use its
466 own internal data structure. Memory consumption is reduced by 1/3
467 and there are modest speed-ups as well. The API is unchanged.
468
Tim Petersde7990b2005-07-17 23:45:23 +0000469- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
470
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000471- SF bug #1229429: PyObject_CallMethod failed to decrement some
472 reference counts in some error exit cases.
473
Tim Petersecc6e6a2005-07-10 22:30:55 +0000474- SF bug #1185883: Python's small-object memory allocator took over
475 a block managed by the platform C library whenever a realloc specified
476 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000477 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000478 portable way to copy data from the C-managed block into Python's
479 small-object space without risking a memory fault. Python's small-object
480 realloc now leaves such blocks under the control of the platform C
481 realloc.
482
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000483- SF bug #1232517: An overflow error was not detected properly when
484 attempting to convert a large float to an int in os.utime().
485
Raymond Hettinger3296e692005-06-29 23:29:56 +0000486- SF bug #1224347: hex longs now print with lowercase letters just
487 like their int counterparts.
488
Michael W. Hudson188d4362005-06-20 16:52:57 +0000489- SF bug #1163563: the original fix for bug #1010677 ("thread Module
490 Breaks PyGILState_Ensure()") broke badly in the case of multiple
491 interpreter states; back out that fix and do a better job (see
492 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
493 for a longer write-up of the problem).
494
Michael W. Hudsondf888462005-06-03 14:41:55 +0000495- SF patch #1180995: marshal now uses a binary format by default when
496 serializing floats.
497
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000498- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
499 the routines that promise to produce IEEE 754 binary representations
500 of floats now simply copy bytes around.
501
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000502- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
503 278.
504
Brett Cannonc3647ac2005-04-26 03:45:26 +0000505- patch #1109424: int, long, float, complex, and unicode now check for the
506 proper magic slot for type conversions when subclassed. Previously the
507 magic slot was ignored during conversion. Semantics now match the way
508 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000509 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000510 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000511 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000512
Barry Warsawc8d907c2005-04-19 23:43:40 +0000513- Descriptors defined in C with a PyGetSetDef structure, where the setter is
514 NULL, now raise an AttributeError when attempting to set or delete the
515 attribute. Previously a TypeError was raised, but this was inconsistent
516 with the equivalent pure-Python implementation.
517
Michael W. Hudson774479c2005-04-18 08:46:17 +0000518- It is now safe to call PyGILState_Release() before
519 PyEval_InitThreads() (note that if there is reason to believe there
520 are multiple threads around you still must call PyEval_InitThreads()
521 before using the Python API; this fix is for extension modules that
522 have no way of knowing if Python is multi-threaded yet).
523
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000524- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
525 disabled caused a crash.
526
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000527- Bug #1165306: instancemethod_new allowed the creation of a method
528 with im_class == im_self == NULL, which caused a crash when called.
529
Tim Petersecc6e6a2005-07-10 22:30:55 +0000530- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000531 fixes the crash seen in bug #1165761
532
Raymond Hettinger96229b12005-03-11 06:49:40 +0000533- Added two new builtins, any() and all().
534
Brett Cannon409d8f22005-03-05 06:47:57 +0000535- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000536 (e.g., ``class C(): pass`` is no longer a syntax error).
537 Patch #1176012 added support to the 'parser' module and 'compiler' package
538 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000539
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000540- Patch #1115086: Support PY_LONGLONG in structmember.
541
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000542- Bug #1155938: new style classes did not check that __init__() was
543 returning None.
544
Tim Petersecc6e6a2005-07-10 22:30:55 +0000545- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000546 ('\') with a specific error message.
547
Martin v. Löwisff232d72005-03-03 09:24:38 +0000548- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
549
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000550- Bug #1124295: the __name__ attribute of file objects was
551 inadvertently made inaccessible in restricted mode.
552
Tim Petersecc6e6a2005-07-10 22:30:55 +0000553- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000554 an ferror() call.
555
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000556- min() and max() now support key= arguments with the same meaning as in
557 list.sort().
558
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000559- The peephole optimizer now performs simple constant folding in expressions:
560 (2+3) --> (5).
561
Raymond Hettingera422c342005-01-11 03:03:27 +0000562- set and frozenset objects can now be marshalled. SF #1098985.
563
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000564- Bug #1077106: Poor argument checking could cause memory corruption
565 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000566
Jeremy Hyltonab630502005-02-04 18:44:06 +0000567- The parser did not complain about future statements in illegal
568 positions. It once again reports a syntax error if a future
569 statement occurs after anything other than a doc string.
570
Neil Schemenauercf52c072005-08-12 17:34:58 +0000571- Change the %s format specifier for str objects so that it returns a
572 unicode instance if the argument is not an instance of basestring and
573 calling __str__ on the argument returns a unicode instance.
574
Tim Petersf4e69282006-02-27 17:15:31 +0000575- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
576 current thread state when the auto-GIL-state machinery knows about
577 it (since the thread state is being deleted, continuing to remember it
578 can't help, but can hurt if another thread happens to get created with
579 the same thread id).
580
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000581Extension Modules
582-----------------
583
Georg Brandl43f08a82006-03-31 18:01:16 +0000584- Patch #1380952: fix SSL objects timing out on consecutive read()s
585
Neal Norwitz05a45592006-03-20 06:30:08 +0000586- Patch #1309579: wait3 and wait4 were added to the posix module.
587
Anthony Baxterfa869072006-03-20 05:21:58 +0000588- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
589 In addition, the existing ulaw code was updated.
590
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000591- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000592 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000593
Neal Norwitz10be10c2006-03-16 06:50:13 +0000594- Everything under lib-old was removed. This includes the following modules:
595 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000596 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000597 util, whatsound, whrandom, zmod
598
599- The following modules were removed: regsub, reconvert, regex, regex_syntax.
600
601- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000602 is deprecated. The undocumented re.engine variable no longer exists.
603
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000604- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
605 SS2 (single-shift 2) escape sequences correctly.
606
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000607- The unicodedata module was updated to the 4.1 version of the Unicode

769-------
770
Nick Coghlan43832302006-04-23 17:04:07 +0000771- PEP 338: new module runpy defines a run_module function to support
772 executing modules which provide access to source code or a code object
773 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000786 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000787 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000788 module will not be built.
789
Tim Petersc17976e2006-04-01 00:26:53 +0000790- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
791 aren't officially supported here, and trying to use them will probably
792 raise an exception some day. But dicts have been allowed, and "mostly
793 worked", so support for them won't go away without warning.
794
Georg Brandl338ef7d2006-03-31 18:42:16 +0000795- Bug #1445068: getpass.getpass() can now be given an explicit stream

813
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000814- email 4.0 package now integrated. This is largely the same as the email 3.0
815 package that was included in Python 2.3, except that PEP 8 module names are
816 now used (e.g. mail.message instead of email.Message). The MIME classes
817 have been moved to a subpackage (e.g. email.mime.text instead of
818 email.MIMEText). The old names are still supported for now. Several
819 deprecated Message methods have been removed and lots of bugs have been
820 fixed. More details can be found in the email package documentation.
821
Walter Dörwald40108c92006-03-27 08:15:44 +0000822- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
823 (a subclass of tuple) that provides incremental decoders and encoders
824 (a way to use stateful codecs without the stream API). Python functions
825 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
826 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
827 have been added.

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

900
Neal Norwitz338e7862005-12-23 21:27:46 +0000901- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
902 LoadError as documented, instead of IOError. For compatibility,
903 LoadError subclasses IOError.
904
Brett Cannon3cbd0382005-12-16 22:49:23 +0000905- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000906 SHA1, 224, 256, 384, and 512. Note that recent developments make the
907 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
908 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
909 Ronald L. Rivest offered this advice for Python:
910
911 "The consensus of researchers in this area (at least as
912 expressed at the NIST Hash Function Workshop 10/31/05),
913 is that SHA-256 is a good choice for the time being, but
914 that research should continue, and other alternatives may
915 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000916
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000917- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001009- The tokenize module now detects and reports indentation errors.
1010 Bug #1224621.
1011
Raymond Hettinger68c04532005-06-10 11:05:19 +00001012- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001013 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001014 the generate_tokens() function now accepts a callable argument that
1015 terminates by raising StopIteration.
1016
Georg Brandl9166e1a2005-06-04 09:20:03 +00001017- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1025 class at all.
1026
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001027- distutils.commands.upload was added to support uploading distribution

1032
Raymond Hettinger267b8682005-03-27 10:47:39 +00001033- decimal operator and comparison methods now return NotImplemented
1034 instead of raising a TypeError when interacting with other types. This
1035 allows other classes to implement __radd__ style methods and have them
1036 work as expected.
1037
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001038- Bug #1163325: Decimal infinities failed to hash. Attempting to
1039 hash a NaN raised an InvalidOperation instead of a TypeError.
1040
Tim Petersecc6e6a2005-07-10 22:30:55 +00001041- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1075
Guido van Rossumd0641422005-02-03 15:01:24 +00001076- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1077 disables recursive traversal through instance attributes, which can
1078 be exploited in various ways.
1079
Tim Peterse3547fd2005-12-16 23:13:57 +00001080- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001081 flags on the HTTP listening socket.
1082
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001083- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1084 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1085
Tim Peterse3547fd2005-12-16 23:13:57 +00001086- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001087 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1088

1090
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001091- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1092
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001093- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1094
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001095- Enhancements to the csv module:
1096
1097 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001098 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001099 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001100 + Dialect parameter parsing has been re-implemented to improve error
1101 reporting.
1102 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1103 dictates.
1104 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001105 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001106 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001107 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1108 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001109 + reader now allows \r characters to be quoted (previously it only allowed
1110 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001111 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001112 + Dialect classes passed to the module are no longer instantiated by
1113 the module before being parsed (the former validation scheme required
1114 this, but the mechanism was unreliable).
1115 + The dialect registry now contains instances of the internal
1116 C-coded dialect type, rather than references to python objects.
1117 + the internal c-coded dialect type is now immutable.
1118 + register_dialect now accepts the same keyword dialect specifications
1119 as the reader and writer, allowing the user to register dialects
1120 without first creating a dialect class.
1121 + a configurable limit to the size of parsed fields has been added -
1122 previously, an unmatched quote character could result in the entire
1123 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001124 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001125 the parser field size limit (returning the former limit). The initial
1126 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001127 + A line_num attribute has been added to the reader object, which tracks
1128 the number of lines read from the source iterator. This is not
1129 the same as the number of records returned, as records can span
1130 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001131 + reader and writer objects were not being registered with the cyclic-GC.
1132 This has been fixed.
1133
Brett Cannone6539c42005-01-08 02:43:53 +00001134- _DummyThread objects in the threading module now delete self.__block that is
1135 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1136 lock primitives tend to be limited in number and thus should not be wasted on
1137 a _DummyThread object. Fixes bug #1089632.
1138
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001139- The imghdr module now detects Exif files.
1140
Raymond Hettinger6065d322004-12-20 23:51:53 +00001141- StringIO.truncate() now correctly adjusts the size attribute.
1142 (Bug #951915).
1143
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001144- locale.py now uses an updated locale alias table (built using
1145 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1146 alias file); the encoding lookup was enhanced to use Python's

Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001148
Raymond Hettinger3557f422004-12-07 12:02:02 +00001149- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1150
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001151- the pickle module no longer accepts the deprecated None option in the
1152 args tuple returned by __reduce__().
1153
Brett Cannon84667c02004-12-07 03:25:18 +00001154- optparse now optionally imports gettext. This allows its use in setup.py.
1155
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001156- the pickle module no longer uses the deprecated bin parameter.
1157
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001158- the shelve module no longer uses the deprecated binary parameter.
1159
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001160- the pstats module no longer uses the deprecated ignore() method.
1161
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001162- the filecmp module no longer uses the deprecated use_statcache argument.
1163
Raymond Hettinger664347b2004-12-04 21:21:53 +00001164- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1165 extended or overridden by subclasses. Formerly, the subclassed method would
1166 be ignored by the rest of the module. (Bug #1078905).
1167
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001168- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001169 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001170
Walter Dörwald36733692004-12-22 12:50:50 +00001171- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1172 once when a size argument is given. This prevents a buffer overflow in the
1173 tokenizer with very long source lines.
1174
Barry Warsaw538561e2006-01-01 21:48:54 +00001175- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1176 immediately after creating the object, without any intervening
1177 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001178
Skip Montanaro05885812005-01-16 20:48:27 +00001179- The reconvert.quote function can now emit triple-quoted strings. The
1180 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001181
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001182- ``UserString.MutableString`` now supports negative indices in
1183 ``__setitem__`` and ``__delitem__``
1184
Greg Ward40407942005-03-05 02:53:17 +00001185- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1186 correctly.
1187
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001188- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1189 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1190 character even if the user has passed a size parameter to get a proper
1191 line ending. Remove the special handling of a "\r\n" that has been split
1192 between two lines.
1193
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001194- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1195 about illegal code points. The codec now supports PEP 293 style error
1196 handlers.
1197
Walter Dörwald78a78b02005-09-01 12:04:29 +00001198- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001199 from the input stream, so that the output is a byte string in the correct
1200 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001201
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001202- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1203 considering it exactly like a '*'.
1204
Walter Dörwald007f8df2005-10-09 19:42:27 +00001205- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1206 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001207
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001208- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1209
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001210- Patch #1413711: Certain patterns of differences were making difflib
1211 touch the recursion limit.
1212
Walter Dörwald58917a62006-03-31 15:26:22 +00001213- Bug #947906: An object oriented interface has been added to the calendar
1214 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001215 called as a script (e.g. via ``python -mcalendar``). Localized month and
1216 weekday names can be ouput (even if an exotic encoding is used) using
1217 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001218
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001219Build
1220-----
1221
Neal Norwitz602d3392006-03-31 08:21:40 +00001222- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1223 by using -mieee gcc option.
1224
Martin v. Löwis86d66262006-02-17 08:40:11 +00001225- Patch #1432345: Make python compile on DragonFly.
1226
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001227- Build support for Win64-AMD64 was added.
1228
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001229- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1230
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001231- Patch #881820: look for openpty and forkpty also in libbsd.
1232
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001233- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1234 The zlib module is now builtin on Windows.
1235
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001236- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1237
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001238- Bug #1189330: configure did not correctly determine the necessary
1239 value of LINKCC if python was built with GCC 4.0.
1240
Trent Mick8321b422005-07-26 02:29:21 +00001241- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1242 vulnerability in zlib 1.2.1 and 1.2.2.
1243
Brett Cannon08cd5982005-04-24 22:26:38 +00001244- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1245 flags that change binary compatibility. Changes were also made to
1246 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001247 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001248
Bob Ippolitoed233462005-03-29 13:47:59 +00001249- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1250 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1251 no longer exists). This configure patch makes things right.
1252
Martin v. Löwise2713be2005-03-08 15:03:08 +00001253- Bug #1158607: Build with --disable-unicode again.
1254
Brett Cannon46d96232005-02-16 00:07:19 +00001255- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1256 defined. Discovered as a result of not being able to build on OS X.
1257
Brett Cannon516592f2004-12-07 00:42:59 +00001258- setup.py now uses the directories specified in LDFLAGS using the -L option
1259 and in CPPFLAGS using the -I option for adding library and include
1260 directories, respectively, for compiling extension modules against. This has
1261 led to the core being compiled using the values in CPPFLAGS. It also removes
1262 the need for the special-casing of both DarwinPorts and Fink for darwin since
1263 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1264 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1265 Fink, ``-I/opt/local/include`` for DarwinPorts).
1266
Brett Cannon43802422005-02-10 20:48:03 +00001267- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1268 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1269 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1270 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001272C API
1273-----
1274
Tim Petersc9d78aa2006-03-26 23:27:58 +00001275- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1276 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1277 is obtained via the ``PyObject_`` family, it must be released via the
1278 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1279 always been officially true, but when Python's small-object allocator was
1280 introduced, an attempt was made to cater to a few extension modules
1281 discovered at the time that obtained memory via ``PyObject_New`` but
1282 released it via ``PyMem_DEL``. It's years later, and if such code still
1283 exists it will fail now (probably with segfaults, but calling wrong
1284 low-level memory management functions can yield many symptoms).
1285
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001286- Added a C API for set and frozenset objects.
1287
Raymond Hettinger66517482004-12-03 11:45:13 +00001288- Removed PyRange_New().
1289
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001290- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1291 mapping argument now. This string is used as a mapping table. Byte values
1292 greater than the length of the string and 0xFFFE are treated as undefined
1293 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001300
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001301- Patch #1276356: New resource "urlfetch" is implemented. This enables
