Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
Anthony Baxterc7d00322006-04-27 02:11:24 +000010*Release date: 27-APR-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Thomas Heller1b046642006-04-18 18:51:06 +000015- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
16 by converting these apis from macros into exported functions again:
17
18 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
19 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
20 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
21 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
22 PyRun_String Py_CompileString
23
Martin v. Löwis45294a92006-04-18 06:24:08 +000024- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
25
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000026- All uses of PyStructSequence_InitType have been changed to initialize
27 the type objects only once, even if the interpreter is initialized
28 multiple times.
29
Neal Norwitz61546162006-04-14 05:20:28 +000030- Bug #1454485, array.array('u') could crash the interpreter. This was
31 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
32 to unicode when it didn't make sense. 'u#' now requires a unicode string.
33
34- Py_UNICODE is unsigned. It was always documented as unsigned, but
35 due to a bug had a signed value in previous versions.
36
Tim Peters3a5e8b12006-04-11 01:44:07 +000037- Patch #837242: ``id()`` of any Python object always gives a positive
38 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
39 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000040 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000041 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000042
Tim Peters3a5e8b12006-04-11 01:44:07 +000043 def __hash__(self):
44 return id(self) # WRONG
45
46 because a hash result must be a (short) Python int but it was always
47 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000048 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000049 was always usable as a hash value before this patch. That's no longer
50 necessarily so.
51
52- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000053 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000054 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000055 #1454844)
56
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000057- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
58 involving generators that have paused outside of any ``try`` or ``with``
59 blocks. (In 2.5a1, a paused generator that was part of a reference
60 cycle could not be garbage collected, regardless of whether it was
61 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +000063Extension Modules
64-----------------
65
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000066- Patch #1191065: Fix preprocessor problems on systems where recvfrom
67 is a macro.
68
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000069- Bug #1467952: os.listdir() now correctly raises an error if readdir()
70 fails with an error condition.
71
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000072- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
73
74- Bug #1117761: bsddb.*open() no longer raises an exception when using
75 the cachesize parameter.
76
77- Bug #1149413: bsddb.*open() no longer raises an exception when using
78 a temporary db (file=None) with the 'n' flag to truncate on open.
79
80- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
81 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000082
Armin Rigoa9017c32006-04-19 11:50:27 +000083- Patch #1062014: AF_UNIX sockets under Linux have a special
84 abstract namespace that is now fully supported.
85
Anthony Baxter51bcb682006-04-05 14:51:42 +000086Library
87-------
88
Georg Brandlfa42bd72006-04-30 07:06:11 +000089- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
90
Tim Peters711bf302006-04-25 03:31:36 +000091- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
92 a doctest to be skipped (the code is not run, and the expected output
93 or exception is ignored).
94
Nick Coghlanda2268f2006-04-24 04:37:15 +000095- Fixed contextlib.nested to cope with exceptions being raised and
96 caught inside exit handlers.
97
Greg Wardab05edc2006-04-23 03:47:58 +000098- Updated optparse module to Optik 1.5.1 (allow numeric constants in
99 hex, octal, or binary; add ``append_const`` action; keep going if
100 gettext cannot be imported; added ``OptionParser.destroy()`` method;
101 added ``epilog`` for better help generation).
102
Tim Peters21fbd572006-04-21 21:18:10 +0000103- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
104 called from a thread spawned as a side effect of importing a module.
105
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000106- The pydoc module now supports documenting packages contained in
107 .zip or .egg files.
108
109- The pkgutil module now has several new utility functions, such
110 as ``walk_packages()`` to support working with packages that are either
111 in the filesystem or zip files.
112
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000113- The mailbox module can now modify and delete messages from
114 mailboxes, in addition to simply reading them. Thanks to Gregory
115 K. Johnson for writing the code, and to the 2005 Google Summer of
116 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000117
Tim Petersc7605f22006-04-17 21:12:33 +0000118- The ``__del__`` method of class ``local`` in module ``_threading_local``
119 returned before accomplishing any of its intended cleanup.
120
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000121- Patch #790710: Add breakpoint command lists in pdb.
122
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000123- Patch #1063914: Add Tkinter.Misc.clipboard_get().
124
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000125- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
126
Anthony Baxtere29002c2006-04-12 12:07:31 +0000127- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
128 Windows. Bug #1469163.
129
Phillip J. Eby47032112006-04-11 01:07:43 +0000130- The warnings, linecache, inspect, traceback, site, and doctest modules
131 were updated to work correctly with modules imported from zipfiles or
132 via other PEP 302 __loader__ objects.
133
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000134- Patch #1467770: Reduce usage of subprocess._active to processes which
135 the application hasn't waited on.
136
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000137- Patch #1462222: Fix Tix.Grid.
138
Neal Norwitza31bf182006-04-09 03:35:43 +0000139- Fix exception when doing glob.glob('anything*/')
140
Skip Montanaro262fb922006-04-21 02:31:07 +0000141- The pstats.Stats class accepts an optional stream keyword argument to
142 direct output to an alternate file-like object.
143
Anthony Baxter51bcb682006-04-05 14:51:42 +0000144Build
145-----
146
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000147- Patch #1471883: Add --enable-universalsdk.
148
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000149- The Makefile now has a reindent target, which runs reindent.py on
150 the library.
151
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000152- Patch #1470875: Building Python with MS Free Compiler
153
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000154- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000155
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000156- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
157 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000158 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000159 CXX from --with-cxx-main, see description in README.
160
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000161- Patch #1429775: Link extension modules with the shared libpython.
162
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000163- Fixed a libffi build problem on MIPS systems.

168Tests
169-----
170
Nick Coghlanda2268f2006-04-24 04:37:15 +0000171- test_contextlib now checks contextlib.nested can cope with exceptions
172 being raised and caught inside exit handlers.
173
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000174- test_cmd_line now checks operation of the -m and -c command switches
175
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000176- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
177 it separately and by hand. It also wasn't cleaning up its changes to
178 the current Decimal context.
179
Thomas Woutersabd08882006-04-26 15:53:30 +0000180- regrtest.py now has a -M option to run tests that test the new limits of
181 containers, on 64-bit architectures. Running these tests is only sensible
182 on 64-bit machines with more than two gigabytes of memory. The argument
183 passed is the maximum amount of memory for the tests to use.

187
188- Added the Python benchmark suite pybench to the Tools/ directory;
189 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000191Documentation
192-------------
193
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000194- PEP 343: Added Context Types section to the library reference
195 and attempted to bring other PEP 343 related documentation into
196 line with the implementation and/or python-dev discussions.
197
Tim Peters8dc73d22006-04-24 02:03:16 +0000198- Bug #1337990: clarified that ``doctest`` does not support examples
199 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000202What's New in Python 2.5 alpha 1?
203=================================
204
Anthony Baxterebed3f62006-04-03 15:03:44 +0000205*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000206
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000207Core and builtins
208-----------------
209
Nick Coghlan43832302006-04-23 17:04:07 +0000210- PEP 338: -m command line switch now delegates to runpy.run_module
211 allowing it to support modules in packages and zipfiles
212
Martin v. Löwisc661b882006-04-20 04:54:23 +0000213- On Windows, .DLL is not an accepted file name extension for
214 extension modules anymore; extensions are only found if they
215 end in .PYD.
216
Martin v. Löwisea62d252006-04-03 10:56:49 +0000217- Bug #1421664: sys.stderr.encoding is now set to the same value as
218 sys.stdout.encoding.
219
Neal Norwitz92e212f2006-04-03 04:48:37 +0000220- __import__ accepts keyword arguments.
221
Georg Brandlccadf842006-03-31 18:54:53 +0000222- Patch #1460496: round() now accepts keyword arguments.
223
Anthony Baxter262c00a2006-03-30 10:53:17 +0000224- Fixed bug #1459029 - unicode reprs were double-escaped.
225
Hye-Shik Changd478f342006-03-23 12:32:36 +0000226- Patch #1396919: The system scope threads are reenabled on FreeBSD
227 5.4 and later versions.
228
Neal Norwitze98ccf62006-03-23 05:39:47 +0000229- Bug #1115379: Compiling a Unicode string with an encoding declaration
230 now gives a SyntaxError.
231
Georg Brandlabd1ff82006-03-18 07:59:59 +0000232- Previously, Python code had no easy way to access the contents of a
233 cell object. Now, a ``cell_contents`` attribute has been added
234 (closes patch #1170323).
235
Tim Peterscf79aac2006-03-16 01:14:46 +0000236- Patch #1123430: Python's small-object allocator now returns an arena to
237 the system ``free()`` when all memory within an arena becomes unused
238 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
239 freed. Some applications will see a drop in virtual memory size now,
240 especially long-running applications that, from time to time, temporarily
241 use a large number of small objects. Note that when Python returns an
242 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000243 platform C library will in turn return that memory to the operating system.
244 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000245 appears to be effective at least on Microsoft C and gcc-based systems.
246 Thanks to Evan Jones for hard work and patience.
247
Georg Brandl533ff6f2006-03-08 18:09:27 +0000248- Patch #1434038: property() now uses the getter's docstring if there is
249 no "doc" argument given. This makes it possible to legitimately use
250 property() as a decorator to produce a read-only property.
251
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000252- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
253 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
254 of requiring an int or long in slicing and a few other contexts, enabling
255 other objects (e.g. Numeric Python's integers) to be used as slice indices.
256
Neal Norwitz995acdf2006-03-07 05:01:00 +0000257- Fixed various bugs reported by Coverity's Prevent tool.
258
Brett Cannonbf364092006-03-01 04:25:17 +0000259- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
260 new exception base class, BaseException, which has a new message attribute.
261 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
262 Raising a string exception now raises a DeprecationWarning.
263
Thomas Woutersfb609f42006-02-28 16:37:25 +0000264- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
265 explicitly relative, using 'from .module import name' to mean 'from the same
266 package as this module is in. Imports without dots still default to the
267 old relative-then-absolute, unless 'from __future__ import
268 absolute_import' is used.
269
Brett Cannona7446e32006-02-27 23:39:10 +0000270- Properly check if 'warnings' raises an exception (usually when a filter set
271 to "error" is triggered) when raising a warning for raising string
272 exceptions.
273
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000274- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000275 The name was removed from Include/code.h.
276
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000277- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000278
Guido van Rossum1968ad32006-02-25 22:38:04 +0000279- Patch 1433928:
280 - The copy module now "copies" function objects (as atomic objects).
281 - dict.__getitem__ now looks for a __missing__ hook before raising
282 KeyError.
283
Tim Peters84ef21c2006-02-28 20:39:06 +0000284- PEP 343: with statement implemented. Needs ``from __future__ import
285 with_statement``. Use of 'with' as a variable will generate a warning.
286 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000287 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000288 The following objects have __context__ methods:
289 - The built-in file type.
290 - The thread.LockType type.
291 - The following types defined by the threading module:
292 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
293 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000294
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000295- Fix the encodings package codec search function to only search
296 inside its own package. Fixes problem reported in patch #1433198.
297
298 Note: Codec packages should implement and register their own
299 codec search function. PEP 100 has the details.
300
Martin v. Löwis18e16552006-02-15 17:27:45 +0000301- PEP 353: Using ssize_t as the index type.
302
Neal Norwitzfc76d632006-01-10 06:03:13 +0000303- Patch #1400181, fix unicode string formatting to not use the locale.
304 This is how string objects work. u'%f' could use , instead of .
305 for the decimal point. Now both strings and unicode always use periods.
306
Neal Norwitz671b9e32006-01-09 07:07:12 +0000307- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
308 configure would break checking curses.h.
309
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000310- Bug #959576: The pwd module is now builtin. This allows Python to be
311 built on UNIX platforms without $HOME set.
312

316
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000317- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
318
Neal Norwitze7214a12005-12-18 05:03:17 +0000319- Support for converting hex strings to floats no longer works.
320 This was not portable. float('0x3') now raises a ValueError.
321
Barry Warsaw2a38a862005-12-18 01:27:35 +0000322- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000323 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000324 is now displayed in interactive prompt banner.
325
Georg Brandlfa166682005-12-17 21:45:17 +0000326- Implementation of PEP 341 - Unification of try/except and try/finally.
327 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000328 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000329
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000330- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
331 now encodes backslash correctly.
332
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000333- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
334
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000335- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000336 and long longs.
337
Neal Norwitz67715f02005-11-09 06:59:35 +0000338- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000339 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000340 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000341
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000342- Replaced most Unicode charmap codecs with new ones using the
343 new Unicode translate string feature in the builtin charmap
344 codec; the codecs were created from the mapping tables available
345 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
346 encodings now include a mapping for the Apple logo)
347
Tim Peterse3547fd2005-12-16 23:13:57 +0000348- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000349
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000350- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000351
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000352- A new AST parser implementation was completed. The abstract
353 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000354 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000355
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000356- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000357 The following code now raises a SyntaxError: foo(a = i for i in range(10))
358
Neal Norwitz708e51a2005-10-03 04:48:15 +0000359- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
360
Neal Norwitz11bd1192005-10-03 00:54:56 +0000361- SF Bug #887946: fix segfault when redirecting stdin from a directory.
362 Provide a warning when a directory is passed on the command line.
363
Neal Norwitz40d37812005-10-02 01:48:49 +0000364- Fix segfault with invalid coding.
365
366- SF bug #772896: unknown encoding results in MemoryError.
367
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000368- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000369 supported a __len__() method which evaluated to False when the iterator
370 was empty.
371
Guido van Rossum630db602005-09-20 18:49:54 +0000372- On 64-bit platforms, when __len__() returns a value that cannot be
373 represented as a C int, raise OverflowError.
374
Skip Montanarof8948ca2005-09-19 03:54:46 +0000375- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000376 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000377
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000378- SF bug #893549: parsing keyword arguments was broken with a few format
379 codes.
380
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000381- Changes donated by Elemental Security to make it work on AIX 5.3
382 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
383 bug #105470: test_pwd fails on 64bit system (Opteron).
384
Guido van Rossum539c6622005-09-14 17:49:54 +0000385- Changes donated by Elemental Security to make it work on HP-UX 11 on
386 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
387
Georg Brandl4550b8d2005-08-26 06:43:52 +0000388- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000389 (fixes bug #1119418).
390
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000391- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
392
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000393- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
394 exceptions that cause a function to exit.
395
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000396- The implementation of set() and frozenset() was revised to use its
397 own internal data structure. Memory consumption is reduced by 1/3
398 and there are modest speed-ups as well. The API is unchanged.
399
Tim Petersde7990b2005-07-17 23:45:23 +0000400- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
401
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000402- SF bug #1229429: PyObject_CallMethod failed to decrement some
403 reference counts in some error exit cases.
404
Tim Petersecc6e6a2005-07-10 22:30:55 +0000405- SF bug #1185883: Python's small-object memory allocator took over
406 a block managed by the platform C library whenever a realloc specified
407 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000408 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000409 portable way to copy data from the C-managed block into Python's
410 small-object space without risking a memory fault. Python's small-object
411 realloc now leaves such blocks under the control of the platform C
412 realloc.
413
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000414- SF bug #1232517: An overflow error was not detected properly when
415 attempting to convert a large float to an int in os.utime().
416
Raymond Hettinger3296e692005-06-29 23:29:56 +0000417- SF bug #1224347: hex longs now print with lowercase letters just
418 like their int counterparts.
419
Michael W. Hudson188d4362005-06-20 16:52:57 +0000420- SF bug #1163563: the original fix for bug #1010677 ("thread Module
421 Breaks PyGILState_Ensure()") broke badly in the case of multiple
422 interpreter states; back out that fix and do a better job (see
423 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
424 for a longer write-up of the problem).
425
Michael W. Hudsondf888462005-06-03 14:41:55 +0000426- SF patch #1180995: marshal now uses a binary format by default when
427 serializing floats.
428
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000429- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
430 the routines that promise to produce IEEE 754 binary representations
431 of floats now simply copy bytes around.
432
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000433- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
434 278.
435
Brett Cannonc3647ac2005-04-26 03:45:26 +0000436- patch #1109424: int, long, float, complex, and unicode now check for the
437 proper magic slot for type conversions when subclassed. Previously the
438 magic slot was ignored during conversion. Semantics now match the way
439 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000440 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000441 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000442 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000443
Barry Warsawc8d907c2005-04-19 23:43:40 +0000444- Descriptors defined in C with a PyGetSetDef structure, where the setter is
445 NULL, now raise an AttributeError when attempting to set or delete the
446 attribute. Previously a TypeError was raised, but this was inconsistent
447 with the equivalent pure-Python implementation.
448
Michael W. Hudson774479c2005-04-18 08:46:17 +0000449- It is now safe to call PyGILState_Release() before
450 PyEval_InitThreads() (note that if there is reason to believe there
451 are multiple threads around you still must call PyEval_InitThreads()
452 before using the Python API; this fix is for extension modules that
453 have no way of knowing if Python is multi-threaded yet).
454
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000455- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
456 disabled caused a crash.
457
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000458- Bug #1165306: instancemethod_new allowed the creation of a method
459 with im_class == im_self == NULL, which caused a crash when called.
460
Tim Petersecc6e6a2005-07-10 22:30:55 +0000461- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000462 fixes the crash seen in bug #1165761
463
Raymond Hettinger96229b12005-03-11 06:49:40 +0000464- Added two new builtins, any() and all().
465
Brett Cannon409d8f22005-03-05 06:47:57 +0000466- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000467 (e.g., ``class C(): pass`` is no longer a syntax error).
468 Patch #1176012 added support to the 'parser' module and 'compiler' package
469 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000470
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000471- Patch #1115086: Support PY_LONGLONG in structmember.
472
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000473- Bug #1155938: new style classes did not check that __init__() was
474 returning None.
475
Tim Petersecc6e6a2005-07-10 22:30:55 +0000476- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000477 ('\') with a specific error message.
478
Martin v. Löwisff232d72005-03-03 09:24:38 +0000479- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
480
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000481- Bug #1124295: the __name__ attribute of file objects was
482 inadvertently made inaccessible in restricted mode.
483
Tim Petersecc6e6a2005-07-10 22:30:55 +0000484- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000485 an ferror() call.
486
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000487- min() and max() now support key= arguments with the same meaning as in
488 list.sort().
489
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000490- The peephole optimizer now performs simple constant folding in expressions:
491 (2+3) --> (5).
492
Raymond Hettingera422c342005-01-11 03:03:27 +0000493- set and frozenset objects can now be marshalled. SF #1098985.
494
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000495- Bug #1077106: Poor argument checking could cause memory corruption
496 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000497
Jeremy Hyltonab630502005-02-04 18:44:06 +0000498- The parser did not complain about future statements in illegal
499 positions. It once again reports a syntax error if a future
500 statement occurs after anything other than a doc string.
501
Neil Schemenauercf52c072005-08-12 17:34:58 +0000502- Change the %s format specifier for str objects so that it returns a
503 unicode instance if the argument is not an instance of basestring and
504 calling __str__ on the argument returns a unicode instance.
505
Tim Petersf4e69282006-02-27 17:15:31 +0000506- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
507 current thread state when the auto-GIL-state machinery knows about
508 it (since the thread state is being deleted, continuing to remember it
509 can't help, but can hurt if another thread happens to get created with
510 the same thread id).
511
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000512Extension Modules
513-----------------
514
Georg Brandl43f08a82006-03-31 18:01:16 +0000515- Patch #1380952: fix SSL objects timing out on consecutive read()s
516
Neal Norwitz05a45592006-03-20 06:30:08 +0000517- Patch #1309579: wait3 and wait4 were added to the posix module.

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000524
Neal Norwitz10be10c2006-03-16 06:50:13 +0000525- Everything under lib-old was removed. This includes the following modules:
526 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000527 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000528 util, whatsound, whrandom, zmod
529
530- The following modules were removed: regsub, reconvert, regex, regex_syntax.
531
532- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000533 is deprecated. The undocumented re.engine variable no longer exists.
534
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000535- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
536 SS2 (single-shift 2) escape sequences correctly.
537
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000538- The unicodedata module was updated to the 4.1 version of the Unicode
539 database. The 3.2 version is still available as unicodedata.db_3_2_0
540 for applications that require this specific version (such as IDNA).
541
Neal Norwitzb62c4332006-03-04 18:35:47 +0000542- The timing module is no longer built by default. It was deprecated
543 in PEP 4 in Python 2.0 or earlier.
544
Guido van Rossum1968ad32006-02-25 22:38:04 +0000545- Patch 1433928: Added a new type, defaultdict, to the collections module.
546 This uses the new __missing__ hook behavior added to dict (see above).
547
Georg Brandldbd83392006-02-20 09:42:33 +0000548- Bug #854823: socketmodule now builds on Sun platforms even when
549 INET_ADDRSTRLEN is not defined.
550
Georg Brandlf4f44152006-02-18 22:29:33 +0000551- Patch #1393157: os.startfile() now has an optional argument to specify
552 a "command verb" to invoke on the file.
553
Neal Norwitz082b2df2006-02-07 07:04:46 +0000554- Bug #876637, prevent stack corruption when socket descriptor
555 is larger than FD_SETSIZE.
556
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000557- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
558 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
559 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
560
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000561- Patch #1422385: The nis module now supports access to domains other
562 than the system default domain.
563
Martin v. Löwis14694662006-02-03 12:54:16 +0000564- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
565 are reported, the limit on path name lengths is removed, and stat reports
566 WindowsError now (instead of OSError).
567
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000568- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
569
Neal Norwitz62a21122006-01-25 05:21:55 +0000570- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
571 before the env.
572
Martin v. Löwis11017b12006-01-14 18:12:57 +0000573- Patch #1103116: Basic AF_NETLINK support.
574
Neal Norwitz3b4fff82006-01-11 08:54:45 +0000575- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
576
Neal Norwitz88bbd732006-01-10 07:05:44 +0000577- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
578 Also fix ungetmouse() which did not accept arguments properly.

700-------
701
Nick Coghlan43832302006-04-23 17:04:07 +0000702- PEP 338: new module runpy defines a run_module function to support
703 executing modules which provide access to source code or a code object
704 via the PEP 302 import mechanisms.
705
Anthony Baxter93f5b932006-04-03 08:05:07 +0000706- The email module's parsedate_tz function now sets the daylight savings
707 flag to -1 (unknown) since it can't tell from the date whether it should

714 in attribute values.
715
Anthony Baxterc51ee692006-04-01 00:57:31 +0000716- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000717 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000718 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000719 module will not be built.
720
Tim Petersc17976e2006-04-01 00:26:53 +0000721- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
722 aren't officially supported here, and trying to use them will probably
723 raise an exception some day. But dicts have been allowed, and "mostly
724 worked", so support for them won't go away without warning.
725
Georg Brandl338ef7d2006-03-31 18:42:16 +0000726- Bug #1445068: getpass.getpass() can now be given an explicit stream

744
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000745- email 4.0 package now integrated. This is largely the same as the email 3.0
746 package that was included in Python 2.3, except that PEP 8 module names are
747 now used (e.g. mail.message instead of email.Message). The MIME classes
748 have been moved to a subpackage (e.g. email.mime.text instead of
749 email.MIMEText). The old names are still supported for now. Several
750 deprecated Message methods have been removed and lots of bugs have been
751 fixed. More details can be found in the email package documentation.
752
Walter Dörwald40108c92006-03-27 08:15:44 +0000753- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
754 (a subclass of tuple) that provides incremental decoders and encoders
755 (a way to use stateful codecs without the stream API). Python functions
756 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
757 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
758 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000759
Walter Dörwald067db482006-03-15 22:17:27 +0000760- Patch #1359365: Calling next() on a closed StringIO.String object raises
761 a ValueError instead of a StopIteration now (like file and cString.String do).
762 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
763 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000764
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000765- A regrtest option -w was added to re-run failed tests in verbose mode.

771 grew an optional 'generation' argument.
772
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000773- A library msilib to generate Windows Installer files, and a distutils

775
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000776- PEP 343: new module contextlib.py defines decorator @contextmanager
777 and helpful context managers nested() and closing().
778
Martin v. Löwis415ed932006-02-27 19:56:30 +0000779- The compiler package now supports future imports after the module docstring.
780

791 current file number.
792
Georg Brandl602b9ba2006-02-19 13:26:36 +0000793- Patch #1349274: gettext.install() now optionally installs additional

Tim Peterse3547fd2005-12-16 23:13:57 +0000837 SHA1, 224, 256, 384, and 512. Note that recent developments make the
838 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
839 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
840 Ronald L. Rivest offered this advice for Python:
841
842 "The consensus of researchers in this area (at least as
843 expressed at the NIST Hash Function Workshop 10/31/05),
844 is that SHA-256 is a good choice for the time being, but
845 that research should continue, and other alternatives may
846 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000847
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000848- Added a subset of Fredrik Lundh's ElementTree package. Available

899
Martin v. Löwis56066d22005-08-24 07:38:12 +0000900- Bug #1178484: Return complete lines from codec stream readers
901 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000902 correct line numbers for decoding errors in source code.

919 parameter, but uses the usual "kwargs=None".
920
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000921- textwrap now processes text chunks at O(n) speed instead of O(n**2).

923
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000924- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
925 to W3C name (404 -> 'Not Found'). RFE #1216944.
926

941 Bug #1224621.
942
Raymond Hettinger68c04532005-06-10 11:05:19 +0000943- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000944 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000945 the generate_tokens() function now accepts a callable argument that
946 terminates by raising StopIteration.
947
Georg Brandl9166e1a2005-06-04 09:20:03 +0000948- Bug #1196315: fix weakref.WeakValueDictionary constructor.

956 class at all.
957
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000958- distutils.commands.upload was added to support uploading distribution

960
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000961- distutils.commands.register now encodes the data as UTF-8 before posting
962 them to PyPI.
963
Raymond Hettinger267b8682005-03-27 10:47:39 +0000964- decimal operator and comparison methods now return NotImplemented
965 instead of raising a TypeError when interacting with other types. This
966 allows other classes to implement __radd__ style methods and have them
967 work as expected.
968
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000969- Bug #1163325: Decimal infinities failed to hash. Attempting to
970 hash a NaN raised an InvalidOperation instead of a TypeError.
971
Tim Petersecc6e6a2005-07-10 22:30:55 +0000972- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1006
Guido van Rossumd0641422005-02-03 15:01:24 +00001007- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1008 disables recursive traversal through instance attributes, which can
1009 be exploited in various ways.
1010
Tim Peterse3547fd2005-12-16 23:13:57 +00001011- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001012 flags on the HTTP listening socket.
1013
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001014- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1015 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1016
Tim Peterse3547fd2005-12-16 23:13:57 +00001017- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001018 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1019
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001020- Bug #1110478: Revert os.environ.update to do putenv again.
1021
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001022- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1023
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001024- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1025
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001026- Enhancements to the csv module:
1027
1028 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001029 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001030 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001031 + Dialect parameter parsing has been re-implemented to improve error
1032 reporting.
1033 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1034 dictates.
1035 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001036 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001037 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001038 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1039 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001040 + reader now allows \r characters to be quoted (previously it only allowed
1041 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001042 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001043 + Dialect classes passed to the module are no longer instantiated by
1044 the module before being parsed (the former validation scheme required
1045 this, but the mechanism was unreliable).
1046 + The dialect registry now contains instances of the internal
1047 C-coded dialect type, rather than references to python objects.
1048 + the internal c-coded dialect type is now immutable.
1049 + register_dialect now accepts the same keyword dialect specifications
1050 as the reader and writer, allowing the user to register dialects
1051 without first creating a dialect class.
1052 + a configurable limit to the size of parsed fields has been added -
1053 previously, an unmatched quote character could result in the entire
1054 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001055 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001056 the parser field size limit (returning the former limit). The initial
1057 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001058 + A line_num attribute has been added to the reader object, which tracks
1059 the number of lines read from the source iterator. This is not
1060 the same as the number of records returned, as records can span
1061 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001062 + reader and writer objects were not being registered with the cyclic-GC.
1063 This has been fixed.
1064
Brett Cannone6539c42005-01-08 02:43:53 +00001065- _DummyThread objects in the threading module now delete self.__block that is
1066 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1067 lock primitives tend to be limited in number and thus should not be wasted on
1068 a _DummyThread object. Fixes bug #1089632.
1069
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001070- The imghdr module now detects Exif files.
1071
Raymond Hettinger6065d322004-12-20 23:51:53 +00001072- StringIO.truncate() now correctly adjusts the size attribute.
1073 (Bug #951915).
1074
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001075- locale.py now uses an updated locale alias table (built using
1076 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1077 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001078 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001079
Raymond Hettinger3557f422004-12-07 12:02:02 +00001080- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1081
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001082- the pickle module no longer accepts the deprecated None option in the
1083 args tuple returned by __reduce__().
1084
Brett Cannon84667c02004-12-07 03:25:18 +00001085- optparse now optionally imports gettext. This allows its use in setup.py.
1086
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001087- the pickle module no longer uses the deprecated bin parameter.
1088
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001089- the shelve module no longer uses the deprecated binary parameter.
1090
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001091- the pstats module no longer uses the deprecated ignore() method.
1092
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001093- the filecmp module no longer uses the deprecated use_statcache argument.
1094
Raymond Hettinger664347b2004-12-04 21:21:53 +00001095- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1096 extended or overridden by subclasses. Formerly, the subclassed method would
1097 be ignored by the rest of the module. (Bug #1078905).
1098
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001099- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001100 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001101
Walter Dörwald36733692004-12-22 12:50:50 +00001102- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1103 once when a size argument is given. This prevents a buffer overflow in the
1104 tokenizer with very long source lines.
1105
Barry Warsaw538561e2006-01-01 21:48:54 +00001106- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1107 immediately after creating the object, without any intervening
1108 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001109
Skip Montanaro05885812005-01-16 20:48:27 +00001110- The reconvert.quote function can now emit triple-quoted strings. The
1111 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001112
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001113- ``UserString.MutableString`` now supports negative indices in
1114 ``__setitem__`` and ``__delitem__``
1115
Greg Ward40407942005-03-05 02:53:17 +00001116- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1117 correctly.
1118
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001119- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1120 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1121 character even if the user has passed a size parameter to get a proper
1122 line ending. Remove the special handling of a "\r\n" that has been split
1123 between two lines.
1124
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001125- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1126 about illegal code points. The codec now supports PEP 293 style error
1127 handlers.
1128
Walter Dörwald78a78b02005-09-01 12:04:29 +00001129- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001130 from the input stream, so that the output is a byte string in the correct
1131 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001132
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001133- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1134 considering it exactly like a '*'.
1135
Walter Dörwald007f8df2005-10-09 19:42:27 +00001136- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1137 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001138
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001139- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1140
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001141- Patch #1413711: Certain patterns of differences were making difflib
1142 touch the recursion limit.
1143
Walter Dörwald58917a62006-03-31 15:26:22 +00001144- Bug #947906: An object oriented interface has been added to the calendar
1145 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001146 called as a script (e.g. via ``python -mcalendar``). Localized month and
1147 weekday names can be ouput (even if an exotic encoding is used) using
1148 special classes that use unicode.

1157
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001158- Build support for Win64-AMD64 was added.
1159
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001160- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1161
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001162- Patch #881820: look for openpty and forkpty also in libbsd.
1163
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001164- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1165 The zlib module is now builtin on Windows.
1166
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001167- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1168
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001169- Bug #1189330: configure did not correctly determine the necessary
1170 value of LINKCC if python was built with GCC 4.0.
1171
Trent Mick8321b422005-07-26 02:29:21 +00001172- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1173 vulnerability in zlib 1.2.1 and 1.2.2.
1174
Brett Cannon08cd5982005-04-24 22:26:38 +00001175- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1176 flags that change binary compatibility. Changes were also made to
1177 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001178 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001179
Bob Ippolitoed233462005-03-29 13:47:59 +00001180- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1181 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1182 no longer exists). This configure patch makes things right.
1183
Martin v. Löwise2713be2005-03-08 15:03:08 +00001184- Bug #1158607: Build with --disable-unicode again.
1185
Brett Cannon46d96232005-02-16 00:07:19 +00001186- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1187 defined. Discovered as a result of not being able to build on OS X.
1188
Brett Cannon516592f2004-12-07 00:42:59 +00001189- setup.py now uses the directories specified in LDFLAGS using the -L option
1190 and in CPPFLAGS using the -I option for adding library and include
1191 directories, respectively, for compiling extension modules against. This has
1192 led to the core being compiled using the values in CPPFLAGS. It also removes
1193 the need for the special-casing of both DarwinPorts and Fink for darwin since
1194 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1195 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1196 Fink, ``-I/opt/local/include`` for DarwinPorts).
1197
Brett Cannon43802422005-02-10 20:48:03 +00001198- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1199 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1200 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1201 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001203C API
1204-----
1205
Tim Petersc9d78aa2006-03-26 23:27:58 +00001206- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1207 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1208 is obtained via the ``PyObject_`` family, it must be released via the
1209 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1210 always been officially true, but when Python's small-object allocator was
1211 introduced, an attempt was made to cater to a few extension modules
1212 discovered at the time that obtained memory via ``PyObject_New`` but
1213 released it via ``PyMem_DEL``. It's years later, and if such code still
1214 exists it will fail now (probably with segfaults, but calling wrong
1215 low-level memory management functions can yield many symptoms).
1216
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001217- Added a C API for set and frozenset objects.
1218
Raymond Hettinger66517482004-12-03 11:45:13 +00001219- Removed PyRange_New().
1220
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001221- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1222 mapping argument now. This string is used as a mapping table. Byte values
1223 greater than the length of the string and 0xFFFE are treated as undefined
1224 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001230- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001231
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001232- Patch #1276356: New resource "urlfetch" is implemented. This enables
1233 even impatient people to run tests that require remote files.
