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 Baxter82201742006-04-09 15:07:40 +000062
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
Tim Peters711bf302006-04-25 03:31:36 +000089- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
90 a doctest to be skipped (the code is not run, and the expected output
91 or exception is ignored).
92
Nick Coghlanda2268f2006-04-24 04:37:15 +000093- Fixed contextlib.nested to cope with exceptions being raised and
94 caught inside exit handlers.
95
Greg Wardab05edc2006-04-23 03:47:58 +000096- Updated optparse module to Optik 1.5.1 (allow numeric constants in
97 hex, octal, or binary; add ``append_const`` action; keep going if
98 gettext cannot be imported; added ``OptionParser.destroy()`` method;
99 added ``epilog`` for better help generation).
100
Tim Peters21fbd572006-04-21 21:18:10 +0000101- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
102 called from a thread spawned as a side effect of importing a module.
103
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000104- The pydoc module now supports documenting packages contained in
105 .zip or .egg files.
106
107- The pkgutil module now has several new utility functions, such
108 as ``walk_packages()`` to support working with packages that are either
109 in the filesystem or zip files.
110
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000111- The mailbox module can now modify and delete messages from
112 mailboxes, in addition to simply reading them. Thanks to Gregory
113 K. Johnson for writing the code, and to the 2005 Google Summer of
114 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000115
Tim Petersc7605f22006-04-17 21:12:33 +0000116- The ``__del__`` method of class ``local`` in module ``_threading_local``
117 returned before accomplishing any of its intended cleanup.
118
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000119- Patch #790710: Add breakpoint command lists in pdb.
120
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000121- Patch #1063914: Add Tkinter.Misc.clipboard_get().
122
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000123- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
124
Anthony Baxtere29002c2006-04-12 12:07:31 +0000125- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
126 Windows. Bug #1469163.
127
Phillip J. Eby47032112006-04-11 01:07:43 +0000128- The warnings, linecache, inspect, traceback, site, and doctest modules
129 were updated to work correctly with modules imported from zipfiles or
130 via other PEP 302 __loader__ objects.
131
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000132- Patch #1467770: Reduce usage of subprocess._active to processes which
133 the application hasn't waited on.
134
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000135- Patch #1462222: Fix Tix.Grid.
136
Neal Norwitza31bf182006-04-09 03:35:43 +0000137- Fix exception when doing glob.glob('anything*/')
138
Skip Montanaro262fb922006-04-21 02:31:07 +0000139- The pstats.Stats class accepts an optional stream keyword argument to
140 direct output to an alternate file-like object.
141
Anthony Baxter51bcb682006-04-05 14:51:42 +0000142Build
143-----
144
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000145- Patch #1471883: Add --enable-universalsdk.
146
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000147- The Makefile now has a reindent target, which runs reindent.py on
148 the library.
149
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000150- Patch #1470875: Building Python with MS Free Compiler
151
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000152- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000153
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000154- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
155 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000156 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000157 CXX from --with-cxx-main, see description in README.
158
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000159- Patch #1429775: Link extension modules with the shared libpython.
160
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000161- Fixed a libffi build problem on MIPS systems.

165
166Tests
167-----
168
Nick Coghlanda2268f2006-04-24 04:37:15 +0000169- test_contextlib now checks contextlib.nested can cope with exceptions
170 being raised and caught inside exit handlers.
171
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000172- test_cmd_line now checks operation of the -m and -c command switches
173
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000174- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
175 it separately and by hand. It also wasn't cleaning up its changes to
176 the current Decimal context.
177
Thomas Woutersabd08882006-04-26 15:53:30 +0000178- regrtest.py now has a -M option to run tests that test the new limits of
179 containers, on 64-bit architectures. Running these tests is only sensible
180 on 64-bit machines with more than two gigabytes of memory. The argument
181 passed is the maximum amount of memory for the tests to use.
182
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000183Tools
184-----
185
186- Added the Python benchmark suite pybench to the Tools/ directory;
187 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000189Documentation
190-------------
191
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000192- PEP 343: Added Context Types section to the library reference
193 and attempted to bring other PEP 343 related documentation into
194 line with the implementation and/or python-dev discussions.
195
Tim Peters8dc73d22006-04-24 02:03:16 +0000196- Bug #1337990: clarified that ``doctest`` does not support examples
197 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000200What's New in Python 2.5 alpha 1?
201=================================
202
Anthony Baxterebed3f62006-04-03 15:03:44 +0000203*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000204
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000205Core and builtins
206-----------------
207
Nick Coghlan43832302006-04-23 17:04:07 +0000208- PEP 338: -m command line switch now delegates to runpy.run_module
209 allowing it to support modules in packages and zipfiles
210
Martin v. Löwisc661b882006-04-20 04:54:23 +0000211- On Windows, .DLL is not an accepted file name extension for
212 extension modules anymore; extensions are only found if they
213 end in .PYD.
214
Martin v. Löwisea62d252006-04-03 10:56:49 +0000215- Bug #1421664: sys.stderr.encoding is now set to the same value as
216 sys.stdout.encoding.
217
Neal Norwitz92e212f2006-04-03 04:48:37 +0000218- __import__ accepts keyword arguments.
219
Georg Brandlccadf842006-03-31 18:54:53 +0000220- Patch #1460496: round() now accepts keyword arguments.
221
Anthony Baxter262c00a2006-03-30 10:53:17 +0000222- Fixed bug #1459029 - unicode reprs were double-escaped.
223
Hye-Shik Changd478f342006-03-23 12:32:36 +0000224- Patch #1396919: The system scope threads are reenabled on FreeBSD
225 5.4 and later versions.
226
Neal Norwitze98ccf62006-03-23 05:39:47 +0000227- Bug #1115379: Compiling a Unicode string with an encoding declaration
228 now gives a SyntaxError.
229
Georg Brandlabd1ff82006-03-18 07:59:59 +0000230- Previously, Python code had no easy way to access the contents of a
231 cell object. Now, a ``cell_contents`` attribute has been added
232 (closes patch #1170323).
233
Tim Peterscf79aac2006-03-16 01:14:46 +0000234- Patch #1123430: Python's small-object allocator now returns an arena to
235 the system ``free()`` when all memory within an arena becomes unused
236 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
237 freed. Some applications will see a drop in virtual memory size now,
238 especially long-running applications that, from time to time, temporarily
239 use a large number of small objects. Note that when Python returns an
240 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000241 platform C library will in turn return that memory to the operating system.
242 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000243 appears to be effective at least on Microsoft C and gcc-based systems.
244 Thanks to Evan Jones for hard work and patience.
245
Georg Brandl533ff6f2006-03-08 18:09:27 +0000246- Patch #1434038: property() now uses the getter's docstring if there is
247 no "doc" argument given. This makes it possible to legitimately use
248 property() as a decorator to produce a read-only property.
249
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000250- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
251 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
252 of requiring an int or long in slicing and a few other contexts, enabling
253 other objects (e.g. Numeric Python's integers) to be used as slice indices.
254
Neal Norwitz995acdf2006-03-07 05:01:00 +0000255- Fixed various bugs reported by Coverity's Prevent tool.
256
Brett Cannonbf364092006-03-01 04:25:17 +0000257- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
258 new exception base class, BaseException, which has a new message attribute.
259 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
260 Raising a string exception now raises a DeprecationWarning.
261
Thomas Woutersfb609f42006-02-28 16:37:25 +0000262- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
263 explicitly relative, using 'from .module import name' to mean 'from the same
264 package as this module is in. Imports without dots still default to the
265 old relative-then-absolute, unless 'from __future__ import
266 absolute_import' is used.
267
Brett Cannona7446e32006-02-27 23:39:10 +0000268- Properly check if 'warnings' raises an exception (usually when a filter set
269 to "error" is triggered) when raising a warning for raising string
270 exceptions.
271
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000272- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000273 The name was removed from Include/code.h.
274
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000275- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000276
Guido van Rossum1968ad32006-02-25 22:38:04 +0000277- Patch 1433928:
278 - The copy module now "copies" function objects (as atomic objects).
279 - dict.__getitem__ now looks for a __missing__ hook before raising
280 KeyError.
281
Tim Peters84ef21c2006-02-28 20:39:06 +0000282- PEP 343: with statement implemented. Needs ``from __future__ import
283 with_statement``. Use of 'with' as a variable will generate a warning.
284 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000285 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000286 The following objects have __context__ methods:
287 - The built-in file type.
288 - The thread.LockType type.
289 - The following types defined by the threading module:
290 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
291 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000292
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000293- Fix the encodings package codec search function to only search
294 inside its own package. Fixes problem reported in patch #1433198.
295
296 Note: Codec packages should implement and register their own
297 codec search function. PEP 100 has the details.
298
Martin v. Löwis18e16552006-02-15 17:27:45 +0000299- PEP 353: Using ssize_t as the index type.
300
Neal Norwitzfc76d632006-01-10 06:03:13 +0000301- Patch #1400181, fix unicode string formatting to not use the locale.
302 This is how string objects work. u'%f' could use , instead of .
303 for the decimal point. Now both strings and unicode always use periods.
304
Neal Norwitz671b9e32006-01-09 07:07:12 +0000305- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
306 configure would break checking curses.h.
307
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000308- Bug #959576: The pwd module is now builtin. This allows Python to be
309 built on UNIX platforms without $HOME set.
310
Neal Norwitzc10978f2005-12-19 06:07:16 +0000311- Bug #1072182, fix some potential problems if characters are signed.
312
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000313- Bug #889500, fix line number on SyntaxWarning for global declarations.
314
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000315- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
316
Neal Norwitze7214a12005-12-18 05:03:17 +0000317- Support for converting hex strings to floats no longer works.
318 This was not portable. float('0x3') now raises a ValueError.
319
Barry Warsaw2a38a862005-12-18 01:27:35 +0000320- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000321 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000322 is now displayed in interactive prompt banner.
323
Georg Brandlfa166682005-12-17 21:45:17 +0000324- Implementation of PEP 341 - Unification of try/except and try/finally.
325 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000326 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000327
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000328- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
329 now encodes backslash correctly.
330
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000331- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
332
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000333- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000334 and long longs.
335
Neal Norwitz67715f02005-11-09 06:59:35 +0000336- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000337 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000338 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000339
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000340- Replaced most Unicode charmap codecs with new ones using the
341 new Unicode translate string feature in the builtin charmap
342 codec; the codecs were created from the mapping tables available
343 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
344 encodings now include a mapping for the Apple logo)
345
Tim Peterse3547fd2005-12-16 23:13:57 +0000346- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000347
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000348- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000349
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000350- A new AST parser implementation was completed. The abstract
351 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000352 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000353
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000354- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000355 The following code now raises a SyntaxError: foo(a = i for i in range(10))
356
Neal Norwitz708e51a2005-10-03 04:48:15 +0000357- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
358
Neal Norwitz11bd1192005-10-03 00:54:56 +0000359- SF Bug #887946: fix segfault when redirecting stdin from a directory.
360 Provide a warning when a directory is passed on the command line.
361
Neal Norwitz40d37812005-10-02 01:48:49 +0000362- Fix segfault with invalid coding.
363
364- SF bug #772896: unknown encoding results in MemoryError.
365
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000366- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000367 supported a __len__() method which evaluated to False when the iterator
368 was empty.
369
Guido van Rossum630db602005-09-20 18:49:54 +0000370- On 64-bit platforms, when __len__() returns a value that cannot be
371 represented as a C int, raise OverflowError.
372
Skip Montanarof8948ca2005-09-19 03:54:46 +0000373- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000374 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000375
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000376- SF bug #893549: parsing keyword arguments was broken with a few format
377 codes.
378
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000379- Changes donated by Elemental Security to make it work on AIX 5.3
380 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
381 bug #105470: test_pwd fails on 64bit system (Opteron).
382
Guido van Rossum539c6622005-09-14 17:49:54 +0000383- Changes donated by Elemental Security to make it work on HP-UX 11 on
384 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
385
Georg Brandl4550b8d2005-08-26 06:43:52 +0000386- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000387 (fixes bug #1119418).
388
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000389- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
390
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000391- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
392 exceptions that cause a function to exit.
393
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000394- The implementation of set() and frozenset() was revised to use its
395 own internal data structure. Memory consumption is reduced by 1/3
396 and there are modest speed-ups as well. The API is unchanged.
397
Tim Petersde7990b2005-07-17 23:45:23 +0000398- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
399
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000400- SF bug #1229429: PyObject_CallMethod failed to decrement some
401 reference counts in some error exit cases.
402
Tim Petersecc6e6a2005-07-10 22:30:55 +0000403- SF bug #1185883: Python's small-object memory allocator took over
404 a block managed by the platform C library whenever a realloc specified
405 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000406 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000407 portable way to copy data from the C-managed block into Python's
408 small-object space without risking a memory fault. Python's small-object
409 realloc now leaves such blocks under the control of the platform C
410 realloc.
411
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000412- SF bug #1232517: An overflow error was not detected properly when
413 attempting to convert a large float to an int in os.utime().
414
Raymond Hettinger3296e692005-06-29 23:29:56 +0000415- SF bug #1224347: hex longs now print with lowercase letters just
416 like their int counterparts.
417
Michael W. Hudson188d4362005-06-20 16:52:57 +0000418- SF bug #1163563: the original fix for bug #1010677 ("thread Module
419 Breaks PyGILState_Ensure()") broke badly in the case of multiple
420 interpreter states; back out that fix and do a better job (see
421 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
422 for a longer write-up of the problem).
423
Michael W. Hudsondf888462005-06-03 14:41:55 +0000424- SF patch #1180995: marshal now uses a binary format by default when
425 serializing floats.
426
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000427- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
428 the routines that promise to produce IEEE 754 binary representations
429 of floats now simply copy bytes around.
430
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000431- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
432 278.
433
Brett Cannonc3647ac2005-04-26 03:45:26 +0000434- patch #1109424: int, long, float, complex, and unicode now check for the
435 proper magic slot for type conversions when subclassed. Previously the
436 magic slot was ignored during conversion. Semantics now match the way
437 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000438 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000439 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000440 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000441
Barry Warsawc8d907c2005-04-19 23:43:40 +0000442- Descriptors defined in C with a PyGetSetDef structure, where the setter is
443 NULL, now raise an AttributeError when attempting to set or delete the
444 attribute. Previously a TypeError was raised, but this was inconsistent
445 with the equivalent pure-Python implementation.
446
Michael W. Hudson774479c2005-04-18 08:46:17 +0000447- It is now safe to call PyGILState_Release() before
448 PyEval_InitThreads() (note that if there is reason to believe there
449 are multiple threads around you still must call PyEval_InitThreads()
450 before using the Python API; this fix is for extension modules that
451 have no way of knowing if Python is multi-threaded yet).
452
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000453- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
454 disabled caused a crash.
455
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000456- Bug #1165306: instancemethod_new allowed the creation of a method
457 with im_class == im_self == NULL, which caused a crash when called.
458
Tim Petersecc6e6a2005-07-10 22:30:55 +0000459- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000460 fixes the crash seen in bug #1165761
461
Raymond Hettinger96229b12005-03-11 06:49:40 +0000462- Added two new builtins, any() and all().
463
Brett Cannon409d8f22005-03-05 06:47:57 +0000464- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000465 (e.g., ``class C(): pass`` is no longer a syntax error).
466 Patch #1176012 added support to the 'parser' module and 'compiler' package
467 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000468
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000469- Patch #1115086: Support PY_LONGLONG in structmember.
470
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000471- Bug #1155938: new style classes did not check that __init__() was
472 returning None.
473
Tim Petersecc6e6a2005-07-10 22:30:55 +0000474- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000475 ('\') with a specific error message.
476
Martin v. Löwisff232d72005-03-03 09:24:38 +0000477- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
478
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000479- Bug #1124295: the __name__ attribute of file objects was
480 inadvertently made inaccessible in restricted mode.
481
Tim Petersecc6e6a2005-07-10 22:30:55 +0000482- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000483 an ferror() call.
484
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000485- min() and max() now support key= arguments with the same meaning as in
486 list.sort().
487
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000488- The peephole optimizer now performs simple constant folding in expressions:
489 (2+3) --> (5).
490
Raymond Hettingera422c342005-01-11 03:03:27 +0000491- set and frozenset objects can now be marshalled. SF #1098985.
492
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000493- Bug #1077106: Poor argument checking could cause memory corruption
494 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000495
Jeremy Hyltonab630502005-02-04 18:44:06 +0000496- The parser did not complain about future statements in illegal
497 positions. It once again reports a syntax error if a future
498 statement occurs after anything other than a doc string.
499
Neil Schemenauercf52c072005-08-12 17:34:58 +0000500- Change the %s format specifier for str objects so that it returns a
501 unicode instance if the argument is not an instance of basestring and
502 calling __str__ on the argument returns a unicode instance.
503
Tim Petersf4e69282006-02-27 17:15:31 +0000504- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
505 current thread state when the auto-GIL-state machinery knows about
506 it (since the thread state is being deleted, continuing to remember it
507 can't help, but can hurt if another thread happens to get created with
508 the same thread id).
509
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000510Extension Modules
511-----------------
512
Georg Brandl43f08a82006-03-31 18:01:16 +0000513- Patch #1380952: fix SSL objects timing out on consecutive read()s
514
Neal Norwitz05a45592006-03-20 06:30:08 +0000515- Patch #1309579: wait3 and wait4 were added to the posix module.

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000522
Neal Norwitz10be10c2006-03-16 06:50:13 +0000523- Everything under lib-old was removed. This includes the following modules:
524 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000525 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000526 util, whatsound, whrandom, zmod
527
528- The following modules were removed: regsub, reconvert, regex, regex_syntax.
529
530- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000531 is deprecated. The undocumented re.engine variable no longer exists.
532
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000533- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
534 SS2 (single-shift 2) escape sequences correctly.
535
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000536- The unicodedata module was updated to the 4.1 version of the Unicode
537 database. The 3.2 version is still available as unicodedata.db_3_2_0
538 for applications that require this specific version (such as IDNA).
539
Neal Norwitzb62c4332006-03-04 18:35:47 +0000540- The timing module is no longer built by default. It was deprecated
541 in PEP 4 in Python 2.0 or earlier.
542
Guido van Rossum1968ad32006-02-25 22:38:04 +0000543- Patch 1433928: Added a new type, defaultdict, to the collections module.
544 This uses the new __missing__ hook behavior added to dict (see above).
545
Georg Brandldbd83392006-02-20 09:42:33 +0000546- Bug #854823: socketmodule now builds on Sun platforms even when
547 INET_ADDRSTRLEN is not defined.
548
Georg Brandlf4f44152006-02-18 22:29:33 +0000549- Patch #1393157: os.startfile() now has an optional argument to specify
550 a "command verb" to invoke on the file.
551
Neal Norwitz082b2df2006-02-07 07:04:46 +0000552- Bug #876637, prevent stack corruption when socket descriptor
553 is larger than FD_SETSIZE.
554
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000555- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
556 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
557 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
558
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000559- Patch #1422385: The nis module now supports access to domains other
560 than the system default domain.
561
Martin v. Löwis14694662006-02-03 12:54:16 +0000562- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
563 are reported, the limit on path name lengths is removed, and stat reports
564 WindowsError now (instead of OSError).
565
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000566- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
567
Neal Norwitz62a21122006-01-25 05:21:55 +0000568- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
569 before the env.
570
Martin v. Löwis11017b12006-01-14 18:12:57 +0000571- Patch #1103116: Basic AF_NETLINK support.
572
Neal Norwitz3b4fff82006-01-11 08:54:45 +0000573- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
574
Neal Norwitz88bbd732006-01-10 07:05:44 +0000575- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
576 Also fix ungetmouse() which did not accept arguments properly.

698-------
699
Nick Coghlan43832302006-04-23 17:04:07 +0000700- PEP 338: new module runpy defines a run_module function to support
701 executing modules which provide access to source code or a code object
702 via the PEP 302 import mechanisms.
703
Anthony Baxter93f5b932006-04-03 08:05:07 +0000704- The email module's parsedate_tz function now sets the daylight savings
705 flag to -1 (unknown) since it can't tell from the date whether it should

712 in attribute values.
713
Anthony Baxterc51ee692006-04-01 00:57:31 +0000714- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000715 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000716 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000717 module will not be built.
718
Tim Petersc17976e2006-04-01 00:26:53 +0000719- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
720 aren't officially supported here, and trying to use them will probably
721 raise an exception some day. But dicts have been allowed, and "mostly
722 worked", so support for them won't go away without warning.
723
Georg Brandl338ef7d2006-03-31 18:42:16 +0000724- Bug #1445068: getpass.getpass() can now be given an explicit stream

726
Georg Brandl22ec80b2006-03-31 18:25:44 +0000727- Patch #1462313, bug #1443328: the pickle modules now can handle classes

742
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000743- email 4.0 package now integrated. This is largely the same as the email 3.0
744 package that was included in Python 2.3, except that PEP 8 module names are
745 now used (e.g. mail.message instead of email.Message). The MIME classes
746 have been moved to a subpackage (e.g. email.mime.text instead of
747 email.MIMEText). The old names are still supported for now. Several
748 deprecated Message methods have been removed and lots of bugs have been
749 fixed. More details can be found in the email package documentation.
750
Walter Dörwald40108c92006-03-27 08:15:44 +0000751- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
752 (a subclass of tuple) that provides incremental decoders and encoders
753 (a way to use stateful codecs without the stream API). Python functions
754 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
755 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
756 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000757
Walter Dörwald067db482006-03-15 22:17:27 +0000758- Patch #1359365: Calling next() on a closed StringIO.String object raises
759 a ValueError instead of a StopIteration now (like file and cString.String do).
760 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
761 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000762

773
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000774- PEP 343: new module contextlib.py defines decorator @contextmanager

836 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
837 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
838 Ronald L. Rivest offered this advice for Python:
839
840 "The consensus of researchers in this area (at least as
841 expressed at the NIST Hash Function Workshop 10/31/05),
842 is that SHA-256 is a good choice for the time being, but
843 that research should continue, and other alternatives may
844 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000845
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000846- Added a subset of Fredrik Lundh's ElementTree package. Available

897
Martin v. Löwis56066d22005-08-24 07:38:12 +0000898- Bug #1178484: Return complete lines from codec stream readers
899 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000900 correct line numbers for decoding errors in source code.

917 parameter, but uses the usual "kwargs=None".
918
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000919- textwrap now processes text chunks at O(n) speed instead of O(n**2).

921
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000922- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
923 to W3C name (404 -> 'Not Found'). RFE #1216944.
924
Georg Brandl9e43acf2005-07-04 17:16:07 +0000925- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
926 as this can cause problems with apps closing all file descriptors.

939 Bug #1224621.
940
Raymond Hettinger68c04532005-06-10 11:05:19 +0000941- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000942 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000943 the generate_tokens() function now accepts a callable argument that
944 terminates by raising StopIteration.
945
Georg Brandl9166e1a2005-06-04 09:20:03 +0000946- Bug #1196315: fix weakref.WeakValueDictionary constructor.

950
Skip Montanaro174dd222005-05-14 20:54:16 +0000951- Patch #1120353: The xmlrpclib module provides better, more transparent,
952 support for datetime.{datetime,date,time} objects. With use_datetime set
953 to True, applications shouldn't have to fiddle with the DateTime wrapper
954 class at all.
955
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000956- distutils.commands.upload was added to support uploading distribution

958
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +0000959- distutils.commands.register now encodes the data as UTF-8 before posting
960 them to PyPI.
961
Raymond Hettinger267b8682005-03-27 10:47:39 +0000962- decimal operator and comparison methods now return NotImplemented
963 instead of raising a TypeError when interacting with other types. This
964 allows other classes to implement __radd__ style methods and have them
965 work as expected.
966
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000967- Bug #1163325: Decimal infinities failed to hash. Attempting to
968 hash a NaN raised an InvalidOperation instead of a TypeError.
969
Tim Petersecc6e6a2005-07-10 22:30:55 +0000970- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1002
Raymond Hettingerbab41432005-02-05 01:31:19 +00001003- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1004
Guido van Rossumd0641422005-02-03 15:01:24 +00001005- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1006 disables recursive traversal through instance attributes, which can
1007 be exploited in various ways.
1008
Tim Peterse3547fd2005-12-16 23:13:57 +00001009- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001010 flags on the HTTP listening socket.
1011
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001012- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1013 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1014
Tim Peterse3547fd2005-12-16 23:13:57 +00001015- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001016 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1017
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001018- Bug #1110478: Revert os.environ.update to do putenv again.
1019
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001020- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1021
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001022- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1023
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001024- Enhancements to the csv module:
1025
1026 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001027 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001028 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001029 + Dialect parameter parsing has been re-implemented to improve error
1030 reporting.
1031 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1032 dictates.
1033 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001034 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001035 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001036 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1037 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001038 + reader now allows \r characters to be quoted (previously it only allowed
1039 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001040 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001041 + Dialect classes passed to the module are no longer instantiated by
1042 the module before being parsed (the former validation scheme required
1043 this, but the mechanism was unreliable).
1044 + The dialect registry now contains instances of the internal
1045 C-coded dialect type, rather than references to python objects.
1046 + the internal c-coded dialect type is now immutable.
1047 + register_dialect now accepts the same keyword dialect specifications
1048 as the reader and writer, allowing the user to register dialects
1049 without first creating a dialect class.
1050 + a configurable limit to the size of parsed fields has been added -
1051 previously, an unmatched quote character could result in the entire
1052 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001053 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001054 the parser field size limit (returning the former limit). The initial
1055 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001056 + A line_num attribute has been added to the reader object, which tracks
1057 the number of lines read from the source iterator. This is not
1058 the same as the number of records returned, as records can span
1059 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001060 + reader and writer objects were not being registered with the cyclic-GC.
1061 This has been fixed.
1062
Brett Cannone6539c42005-01-08 02:43:53 +00001063- _DummyThread objects in the threading module now delete self.__block that is
1064 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1065 lock primitives tend to be limited in number and thus should not be wasted on
1066 a _DummyThread object. Fixes bug #1089632.
1067
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001068- The imghdr module now detects Exif files.
1069
Raymond Hettinger6065d322004-12-20 23:51:53 +00001070- StringIO.truncate() now correctly adjusts the size attribute.
1071 (Bug #951915).
1072
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001073- locale.py now uses an updated locale alias table (built using
1074 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1075 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001076 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001077
Raymond Hettinger3557f422004-12-07 12:02:02 +00001078- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1079
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001080- the pickle module no longer accepts the deprecated None option in the
1081 args tuple returned by __reduce__().
1082
Brett Cannon84667c02004-12-07 03:25:18 +00001083- optparse now optionally imports gettext. This allows its use in setup.py.
1084
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001085- the pickle module no longer uses the deprecated bin parameter.
1086
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001087- the shelve module no longer uses the deprecated binary parameter.
1088
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001089- the pstats module no longer uses the deprecated ignore() method.
1090
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001091- the filecmp module no longer uses the deprecated use_statcache argument.
1092
Raymond Hettinger664347b2004-12-04 21:21:53 +00001093- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1094 extended or overridden by subclasses. Formerly, the subclassed method would
1095 be ignored by the rest of the module. (Bug #1078905).
1096
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001097- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001098 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001099
Walter Dörwald36733692004-12-22 12:50:50 +00001100- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1101 once when a size argument is given. This prevents a buffer overflow in the
1102 tokenizer with very long source lines.
1103
Barry Warsaw538561e2006-01-01 21:48:54 +00001104- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1105 immediately after creating the object, without any intervening
1106 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001107
Skip Montanaro05885812005-01-16 20:48:27 +00001108- The reconvert.quote function can now emit triple-quoted strings. The
1109 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001110
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001111- ``UserString.MutableString`` now supports negative indices in
1112 ``__setitem__`` and ``__delitem__``
1113
Greg Ward40407942005-03-05 02:53:17 +00001114- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1115 correctly.
1116
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001117- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1118 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1119 character even if the user has passed a size parameter to get a proper
1120 line ending. Remove the special handling of a "\r\n" that has been split
1121 between two lines.
1122
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001123- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1124 about illegal code points. The codec now supports PEP 293 style error
1125 handlers.
1126
Walter Dörwald78a78b02005-09-01 12:04:29 +00001127- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001128 from the input stream, so that the output is a byte string in the correct
1129 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001130
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001131- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1132 considering it exactly like a '*'.
1133
Walter Dörwald007f8df2005-10-09 19:42:27 +00001134- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1135 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001136
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001137- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1138
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001139- Patch #1413711: Certain patterns of differences were making difflib
1140 touch the recursion limit.
1141
Walter Dörwald58917a62006-03-31 15:26:22 +00001142- Bug #947906: An object oriented interface has been added to the calendar
1143 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001144 called as a script (e.g. via ``python -mcalendar``). Localized month and
1145 weekday names can be ouput (even if an exotic encoding is used) using
1146 special classes that use unicode.

1155
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001156- Build support for Win64-AMD64 was added.
1157
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001158- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1159
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001160- Patch #881820: look for openpty and forkpty also in libbsd.
1161
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001162- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1163 The zlib module is now builtin on Windows.
1164
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001165- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1166
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001167- Bug #1189330: configure did not correctly determine the necessary
1168 value of LINKCC if python was built with GCC 4.0.
1169
Trent Mick8321b422005-07-26 02:29:21 +00001170- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1171 vulnerability in zlib 1.2.1 and 1.2.2.
1172
Brett Cannon08cd5982005-04-24 22:26:38 +00001173- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1174 flags that change binary compatibility. Changes were also made to
1175 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001176 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001177
Bob Ippolitoed233462005-03-29 13:47:59 +00001178- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1179 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1180 no longer exists). This configure patch makes things right.
1181
Martin v. Löwise2713be2005-03-08 15:03:08 +00001182- Bug #1158607: Build with --disable-unicode again.
1183
Brett Cannon46d96232005-02-16 00:07:19 +00001184- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1185 defined. Discovered as a result of not being able to build on OS X.
1186
Brett Cannon516592f2004-12-07 00:42:59 +00001187- setup.py now uses the directories specified in LDFLAGS using the -L option
1188 and in CPPFLAGS using the -I option for adding library and include
1189 directories, respectively, for compiling extension modules against. This has
1190 led to the core being compiled using the values in CPPFLAGS. It also removes
1191 the need for the special-casing of both DarwinPorts and Fink for darwin since
1192 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1193 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1194 Fink, ``-I/opt/local/include`` for DarwinPorts).
1195
Brett Cannon43802422005-02-10 20:48:03 +00001196- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1197 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1198 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1199 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001201C API
1202-----
1203
Tim Petersc9d78aa2006-03-26 23:27:58 +00001204- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1205 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1206 is obtained via the ``PyObject_`` family, it must be released via the
1207 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1208 always been officially true, but when Python's small-object allocator was
1209 introduced, an attempt was made to cater to a few extension modules
1210 discovered at the time that obtained memory via ``PyObject_New`` but
1211 released it via ``PyMem_DEL``. It's years later, and if such code still
1212 exists it will fail now (probably with segfaults, but calling wrong
1213 low-level memory management functions can yield many symptoms).
1214
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001215- Added a C API for set and frozenset objects.
1216

1218
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001219- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1220 mapping argument now. This string is used as a mapping table. Byte values
1221 greater than the length of the string and 0xFFFE are treated as undefined
1222 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001228- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001229
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001230- Patch #1276356: New resource "urlfetch" is implemented. This enables
1231 even impatient people to run tests that require remote files.
