Anthony Baxter51bcb682006-04-05 14:51:42 +00007What's New in Python 2.5 alpha 2?
8=================================
9
10*Release date: XX-XXX-2006*
11
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. Löwis4be4e652006-04-17 19:25:49 +0000145- The Makefile now has a reindent target, which runs reindent.py on
146 the library.
147
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000148- Patch #1470875: Building Python with MS Free Compiler
149
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000150- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000151
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000152- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
153 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000154 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000155 CXX from --with-cxx-main, see description in README.
156
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000157- Patch #1429775: Link extension modules with the shared libpython.
158
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000159- Fixed a libffi build problem on MIPS systems.

163
164Tests
165-----
166
Nick Coghlanda2268f2006-04-24 04:37:15 +0000167- test_contextlib now checks contextlib.nested can cope with exceptions
168 being raised and caught inside exit handlers.
169
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000170- test_cmd_line now checks operation of the -m and -c command switches
171
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000172- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
173 it separately and by hand. It also wasn't cleaning up its changes to
174 the current Decimal context.
175
Thomas Woutersabd08882006-04-26 15:53:30 +0000176- regrtest.py now has a -M option to run tests that test the new limits of
177 containers, on 64-bit architectures. Running these tests is only sensible
178 on 64-bit machines with more than two gigabytes of memory. The argument
179 passed is the maximum amount of memory for the tests to use.
180
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000181Tools
182-----
183
184- Added the Python benchmark suite pybench to the Tools/ directory;
185 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000187Documentation
188-------------
189
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000190- PEP 343: Added Context Types section to the library reference
191 and attempted to bring other PEP 343 related documentation into
192 line with the implementation and/or python-dev discussions.
193
Tim Peters8dc73d22006-04-24 02:03:16 +0000194- Bug #1337990: clarified that ``doctest`` does not support examples
195 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000198What's New in Python 2.5 alpha 1?
199=================================
200
Anthony Baxterebed3f62006-04-03 15:03:44 +0000201*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000202
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000203Core and builtins
204-----------------
205
Nick Coghlan43832302006-04-23 17:04:07 +0000206- PEP 338: -m command line switch now delegates to runpy.run_module
207 allowing it to support modules in packages and zipfiles
208
Martin v. Löwisc661b882006-04-20 04:54:23 +0000209- On Windows, .DLL is not an accepted file name extension for
210 extension modules anymore; extensions are only found if they
211 end in .PYD.
212
Martin v. Löwisea62d252006-04-03 10:56:49 +0000213- Bug #1421664: sys.stderr.encoding is now set to the same value as
214 sys.stdout.encoding.
215
Neal Norwitz92e212f2006-04-03 04:48:37 +0000216- __import__ accepts keyword arguments.
217
Georg Brandlccadf842006-03-31 18:54:53 +0000218- Patch #1460496: round() now accepts keyword arguments.
219
Anthony Baxter262c00a2006-03-30 10:53:17 +0000220- Fixed bug #1459029 - unicode reprs were double-escaped.
221
Hye-Shik Changd478f342006-03-23 12:32:36 +0000222- Patch #1396919: The system scope threads are reenabled on FreeBSD
223 5.4 and later versions.
224
Neal Norwitze98ccf62006-03-23 05:39:47 +0000225- Bug #1115379: Compiling a Unicode string with an encoding declaration
226 now gives a SyntaxError.
227
Georg Brandlabd1ff82006-03-18 07:59:59 +0000228- Previously, Python code had no easy way to access the contents of a
229 cell object. Now, a ``cell_contents`` attribute has been added
230 (closes patch #1170323).
231
Tim Peterscf79aac2006-03-16 01:14:46 +0000232- Patch #1123430: Python's small-object allocator now returns an arena to
233 the system ``free()`` when all memory within an arena becomes unused
234 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
235 freed. Some applications will see a drop in virtual memory size now,
236 especially long-running applications that, from time to time, temporarily
237 use a large number of small objects. Note that when Python returns an
238 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000239 platform C library will in turn return that memory to the operating system.
240 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000241 appears to be effective at least on Microsoft C and gcc-based systems.
242 Thanks to Evan Jones for hard work and patience.
243
Georg Brandl533ff6f2006-03-08 18:09:27 +0000244- Patch #1434038: property() now uses the getter's docstring if there is
245 no "doc" argument given. This makes it possible to legitimately use
246 property() as a decorator to produce a read-only property.
247
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000248- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
249 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
250 of requiring an int or long in slicing and a few other contexts, enabling
251 other objects (e.g. Numeric Python's integers) to be used as slice indices.
252
Neal Norwitz995acdf2006-03-07 05:01:00 +0000253- Fixed various bugs reported by Coverity's Prevent tool.
254
Brett Cannonbf364092006-03-01 04:25:17 +0000255- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
256 new exception base class, BaseException, which has a new message attribute.
257 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
258 Raising a string exception now raises a DeprecationWarning.
259
Thomas Woutersfb609f42006-02-28 16:37:25 +0000260- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
261 explicitly relative, using 'from .module import name' to mean 'from the same
262 package as this module is in. Imports without dots still default to the
263 old relative-then-absolute, unless 'from __future__ import
264 absolute_import' is used.
265
Brett Cannona7446e32006-02-27 23:39:10 +0000266- Properly check if 'warnings' raises an exception (usually when a filter set
267 to "error" is triggered) when raising a warning for raising string
268 exceptions.
269
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000270- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000271 The name was removed from Include/code.h.
272
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000273- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000274
Guido van Rossum1968ad32006-02-25 22:38:04 +0000275- Patch 1433928:
276 - The copy module now "copies" function objects (as atomic objects).
277 - dict.__getitem__ now looks for a __missing__ hook before raising
278 KeyError.
279
Tim Peters84ef21c2006-02-28 20:39:06 +0000280- PEP 343: with statement implemented. Needs ``from __future__ import
281 with_statement``. Use of 'with' as a variable will generate a warning.
282 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000283 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000284 The following objects have __context__ methods:
285 - The built-in file type.
286 - The thread.LockType type.
287 - The following types defined by the threading module:
288 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
289 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000290
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000291- Fix the encodings package codec search function to only search
292 inside its own package. Fixes problem reported in patch #1433198.
293
294 Note: Codec packages should implement and register their own
295 codec search function. PEP 100 has the details.
296
Martin v. Löwis18e16552006-02-15 17:27:45 +0000297- PEP 353: Using ssize_t as the index type.
298
Neal Norwitzfc76d632006-01-10 06:03:13 +0000299- Patch #1400181, fix unicode string formatting to not use the locale.
300 This is how string objects work. u'%f' could use , instead of .
301 for the decimal point. Now both strings and unicode always use periods.
302
Neal Norwitz671b9e32006-01-09 07:07:12 +0000303- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
304 configure would break checking curses.h.
305
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000306- Bug #959576: The pwd module is now builtin. This allows Python to be
307 built on UNIX platforms without $HOME set.
308
Neal Norwitzc10978f2005-12-19 06:07:16 +0000309- Bug #1072182, fix some potential problems if characters are signed.
310
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000311- Bug #889500, fix line number on SyntaxWarning for global declarations.
312
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000313- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
314
Neal Norwitze7214a12005-12-18 05:03:17 +0000315- Support for converting hex strings to floats no longer works.
316 This was not portable. float('0x3') now raises a ValueError.
317
Barry Warsaw2a38a862005-12-18 01:27:35 +0000318- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000319 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000320 is now displayed in interactive prompt banner.
321
Georg Brandlfa166682005-12-17 21:45:17 +0000322- Implementation of PEP 341 - Unification of try/except and try/finally.
323 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000324 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000325
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000326- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
327 now encodes backslash correctly.
328
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000329- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
330
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000331- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000332 and long longs.
333
Neal Norwitz67715f02005-11-09 06:59:35 +0000334- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000335 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000336 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000337
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000338- Replaced most Unicode charmap codecs with new ones using the
339 new Unicode translate string feature in the builtin charmap
340 codec; the codecs were created from the mapping tables available
341 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
342 encodings now include a mapping for the Apple logo)
343
Tim Peterse3547fd2005-12-16 23:13:57 +0000344- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000345
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000346- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000347
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000348- A new AST parser implementation was completed. The abstract
349 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000350 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000351
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000352- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000353 The following code now raises a SyntaxError: foo(a = i for i in range(10))
354
Neal Norwitz708e51a2005-10-03 04:48:15 +0000355- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
356
Neal Norwitz11bd1192005-10-03 00:54:56 +0000357- SF Bug #887946: fix segfault when redirecting stdin from a directory.
358 Provide a warning when a directory is passed on the command line.
359
Neal Norwitz40d37812005-10-02 01:48:49 +0000360- Fix segfault with invalid coding.
361
362- SF bug #772896: unknown encoding results in MemoryError.
363
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000364- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000365 supported a __len__() method which evaluated to False when the iterator
366 was empty.
367
Guido van Rossum630db602005-09-20 18:49:54 +0000368- On 64-bit platforms, when __len__() returns a value that cannot be
369 represented as a C int, raise OverflowError.
370
Skip Montanarof8948ca2005-09-19 03:54:46 +0000371- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000372 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000373
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000374- SF bug #893549: parsing keyword arguments was broken with a few format
375 codes.
376
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000377- Changes donated by Elemental Security to make it work on AIX 5.3
378 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
379 bug #105470: test_pwd fails on 64bit system (Opteron).
380
Guido van Rossum539c6622005-09-14 17:49:54 +0000381- Changes donated by Elemental Security to make it work on HP-UX 11 on
382 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
383
Georg Brandl4550b8d2005-08-26 06:43:52 +0000384- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000385 (fixes bug #1119418).
386
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000387- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
388
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000389- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
390 exceptions that cause a function to exit.
391
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000392- The implementation of set() and frozenset() was revised to use its
393 own internal data structure. Memory consumption is reduced by 1/3
394 and there are modest speed-ups as well. The API is unchanged.
395
Tim Petersde7990b2005-07-17 23:45:23 +0000396- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
397
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000398- SF bug #1229429: PyObject_CallMethod failed to decrement some
399 reference counts in some error exit cases.
400
Tim Petersecc6e6a2005-07-10 22:30:55 +0000401- SF bug #1185883: Python's small-object memory allocator took over
402 a block managed by the platform C library whenever a realloc specified
403 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000404 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000405 portable way to copy data from the C-managed block into Python's
406 small-object space without risking a memory fault. Python's small-object
407 realloc now leaves such blocks under the control of the platform C
408 realloc.
409
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000410- SF bug #1232517: An overflow error was not detected properly when
411 attempting to convert a large float to an int in os.utime().
412
Raymond Hettinger3296e692005-06-29 23:29:56 +0000413- SF bug #1224347: hex longs now print with lowercase letters just
414 like their int counterparts.
415
Michael W. Hudson188d4362005-06-20 16:52:57 +0000416- SF bug #1163563: the original fix for bug #1010677 ("thread Module
417 Breaks PyGILState_Ensure()") broke badly in the case of multiple
418 interpreter states; back out that fix and do a better job (see
419 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
420 for a longer write-up of the problem).
421
Michael W. Hudsondf888462005-06-03 14:41:55 +0000422- SF patch #1180995: marshal now uses a binary format by default when
423 serializing floats.
424
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000425- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
426 the routines that promise to produce IEEE 754 binary representations
427 of floats now simply copy bytes around.
428
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000429- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
430 278.
431
Brett Cannonc3647ac2005-04-26 03:45:26 +0000432- patch #1109424: int, long, float, complex, and unicode now check for the
433 proper magic slot for type conversions when subclassed. Previously the
434 magic slot was ignored during conversion. Semantics now match the way
435 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000436 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000437 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000438 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000439
Barry Warsawc8d907c2005-04-19 23:43:40 +0000440- Descriptors defined in C with a PyGetSetDef structure, where the setter is
441 NULL, now raise an AttributeError when attempting to set or delete the
442 attribute. Previously a TypeError was raised, but this was inconsistent
443 with the equivalent pure-Python implementation.
444
Michael W. Hudson774479c2005-04-18 08:46:17 +0000445- It is now safe to call PyGILState_Release() before
446 PyEval_InitThreads() (note that if there is reason to believe there
447 are multiple threads around you still must call PyEval_InitThreads()
448 before using the Python API; this fix is for extension modules that
449 have no way of knowing if Python is multi-threaded yet).
450
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000451- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
452 disabled caused a crash.
453
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000454- Bug #1165306: instancemethod_new allowed the creation of a method
455 with im_class == im_self == NULL, which caused a crash when called.
456
Tim Petersecc6e6a2005-07-10 22:30:55 +0000457- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000458 fixes the crash seen in bug #1165761
459
Raymond Hettinger96229b12005-03-11 06:49:40 +0000460- Added two new builtins, any() and all().
461
Brett Cannon409d8f22005-03-05 06:47:57 +0000462- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000463 (e.g., ``class C(): pass`` is no longer a syntax error).
464 Patch #1176012 added support to the 'parser' module and 'compiler' package
465 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000466
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000467- Patch #1115086: Support PY_LONGLONG in structmember.
468
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000469- Bug #1155938: new style classes did not check that __init__() was
470 returning None.
471
Tim Petersecc6e6a2005-07-10 22:30:55 +0000472- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000473 ('\') with a specific error message.
474
Martin v. Löwisff232d72005-03-03 09:24:38 +0000475- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
476
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000477- Bug #1124295: the __name__ attribute of file objects was
478 inadvertently made inaccessible in restricted mode.
479
Tim Petersecc6e6a2005-07-10 22:30:55 +0000480- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000481 an ferror() call.
482
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000483- min() and max() now support key= arguments with the same meaning as in
484 list.sort().
485
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000486- The peephole optimizer now performs simple constant folding in expressions:
487 (2+3) --> (5).
488
Raymond Hettingera422c342005-01-11 03:03:27 +0000489- set and frozenset objects can now be marshalled. SF #1098985.
490
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000491- Bug #1077106: Poor argument checking could cause memory corruption
492 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000493
Jeremy Hyltonab630502005-02-04 18:44:06 +0000494- The parser did not complain about future statements in illegal
495 positions. It once again reports a syntax error if a future
496 statement occurs after anything other than a doc string.
497
Neil Schemenauercf52c072005-08-12 17:34:58 +0000498- Change the %s format specifier for str objects so that it returns a
499 unicode instance if the argument is not an instance of basestring and
500 calling __str__ on the argument returns a unicode instance.
501
Tim Petersf4e69282006-02-27 17:15:31 +0000502- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
503 current thread state when the auto-GIL-state machinery knows about
504 it (since the thread state is being deleted, continuing to remember it
505 can't help, but can hurt if another thread happens to get created with
506 the same thread id).
507
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000508Extension Modules
509-----------------
510
Georg Brandl43f08a82006-03-31 18:01:16 +0000511- Patch #1380952: fix SSL objects timing out on consecutive read()s
512
Neal Norwitz05a45592006-03-20 06:30:08 +0000513- Patch #1309579: wait3 and wait4 were added to the posix module.

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000520
Neal Norwitz10be10c2006-03-16 06:50:13 +0000521- Everything under lib-old was removed. This includes the following modules:
522 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000523 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000524 util, whatsound, whrandom, zmod
525
526- The following modules were removed: regsub, reconvert, regex, regex_syntax.
527
528- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000529 is deprecated. The undocumented re.engine variable no longer exists.
530
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000531- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
532 SS2 (single-shift 2) escape sequences correctly.
533
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000534- The unicodedata module was updated to the 4.1 version of the Unicode
535 database. The 3.2 version is still available as unicodedata.db_3_2_0
536 for applications that require this specific version (such as IDNA).
537
Neal Norwitzb62c4332006-03-04 18:35:47 +0000538- The timing module is no longer built by default. It was deprecated
539 in PEP 4 in Python 2.0 or earlier.
540
Guido van Rossum1968ad32006-02-25 22:38:04 +0000541- Patch 1433928: Added a new type, defaultdict, to the collections module.
542 This uses the new __missing__ hook behavior added to dict (see above).
543
Georg Brandldbd83392006-02-20 09:42:33 +0000544- Bug #854823: socketmodule now builds on Sun platforms even when
545 INET_ADDRSTRLEN is not defined.
546
Georg Brandlf4f44152006-02-18 22:29:33 +0000547- Patch #1393157: os.startfile() now has an optional argument to specify
548 a "command verb" to invoke on the file.
549
Neal Norwitz082b2df2006-02-07 07:04:46 +0000550- Bug #876637, prevent stack corruption when socket descriptor
551 is larger than FD_SETSIZE.
552
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000553- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
554 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
555 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
556
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000557- Patch #1422385: The nis module now supports access to domains other
558 than the system default domain.
559
Martin v. Löwis14694662006-02-03 12:54:16 +0000560- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
561 are reported, the limit on path name lengths is removed, and stat reports
562 WindowsError now (instead of OSError).
563
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000564- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
565
Neal Norwitz62a21122006-01-25 05:21:55 +0000566- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
567 before the env.
568

572
Neal Norwitz88bbd732006-01-10 07:05:44 +0000573- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
574 Also fix ungetmouse() which did not accept arguments properly.
575 The code now conforms to the documented signature.
576
Neal Norwitz5e3d8622006-01-09 06:24:35 +0000577- Bug #1400115, Fix segfault when calling curses.panel.userptr()
578 without prior setting of the userptr.
579

696-------
697
Nick Coghlan43832302006-04-23 17:04:07 +0000698- PEP 338: new module runpy defines a run_module function to support
699 executing modules which provide access to source code or a code object
700 via the PEP 302 import mechanisms.
701
Anthony Baxter93f5b932006-04-03 08:05:07 +0000702- The email module's parsedate_tz function now sets the daylight savings
703 flag to -1 (unknown) since it can't tell from the date whether it should

710 in attribute values.
711
Anthony Baxterc51ee692006-04-01 00:57:31 +0000712- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000713 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000714 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000715 module will not be built.
716
Tim Petersc17976e2006-04-01 00:26:53 +0000717- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
718 aren't officially supported here, and trying to use them will probably
719 raise an exception some day. But dicts have been allowed, and "mostly
720 worked", so support for them won't go away without warning.
721
Georg Brandl338ef7d2006-03-31 18:42:16 +0000722- Bug #1445068: getpass.getpass() can now be given an explicit stream
723 argument to specify where to write the prompt.
724
Georg Brandl22ec80b2006-03-31 18:25:44 +0000725- Patch #1462313, bug #1443328: the pickle modules now can handle classes

732
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000733- Queue.Queue objects now support .task_done() and .join() methods
734 to make it easier to monitor when daemon threads have completed

740
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000741- email 4.0 package now integrated. This is largely the same as the email 3.0
742 package that was included in Python 2.3, except that PEP 8 module names are
743 now used (e.g. mail.message instead of email.Message). The MIME classes
744 have been moved to a subpackage (e.g. email.mime.text instead of
745 email.MIMEText). The old names are still supported for now. Several
746 deprecated Message methods have been removed and lots of bugs have been
747 fixed. More details can be found in the email package documentation.
748
Walter Dörwald40108c92006-03-27 08:15:44 +0000749- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
750 (a subclass of tuple) that provides incremental decoders and encoders
751 (a way to use stateful codecs without the stream API). Python functions
752 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
753 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
754 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000755
Walter Dörwald067db482006-03-15 22:17:27 +0000756- Patch #1359365: Calling next() on a closed StringIO.String object raises
757 a ValueError instead of a StopIteration now (like file and cString.String do).
758 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
759 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000760
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000761- A regrtest option -w was added to re-run failed tests in verbose mode.

765
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000766- The function get_count() has been added to the gc module, and gc.collect()
767 grew an optional 'generation' argument.
768
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000769- A library msilib to generate Windows Installer files, and a distutils
770 command bdist_msi have been added.
771
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000772- PEP 343: new module contextlib.py defines decorator @contextmanager
773 and helpful context managers nested() and closing().
774
Martin v. Löwis415ed932006-02-27 19:56:30 +0000775- The compiler package now supports future imports after the module docstring.
776

787 current file number.
788
Georg Brandl602b9ba2006-02-19 13:26:36 +0000789- Patch #1349274: gettext.install() now optionally installs additional

Tim Peterse3547fd2005-12-16 23:13:57 +0000833 SHA1, 224, 256, 384, and 512. Note that recent developments make the
834 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
835 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
836 Ronald L. Rivest offered this advice for Python:
837
838 "The consensus of researchers in this area (at least as
839 expressed at the NIST Hash Function Workshop 10/31/05),
840 is that SHA-256 is a good choice for the time being, but
841 that research should continue, and other alternatives may
842 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000843
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000844- Added a subset of Fredrik Lundh's ElementTree package. Available

895
Martin v. Löwis56066d22005-08-24 07:38:12 +0000896- Bug #1178484: Return complete lines from codec stream readers
897 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000898 correct line numbers for decoding errors in source code.

915 parameter, but uses the usual "kwargs=None".
916
Andrew M. Kuchling88b85822005-08-23 00:57:07 +0000917- textwrap now processes text chunks at O(n) speed instead of O(n**2).

919
Georg Brandl5c5fe2f2005-07-14 06:40:47 +0000920- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
921 to W3C name (404 -> 'Not Found'). RFE #1216944.
922
Georg Brandl9e43acf2005-07-04 17:16:07 +0000923- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
924 as this can cause problems with apps closing all file descriptors.

937 Bug #1224621.
938
Raymond Hettinger68c04532005-06-10 11:05:19 +0000939- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000940 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000941 the generate_tokens() function now accepts a callable argument that
942 terminates by raising StopIteration.
943
Georg Brandl9166e1a2005-06-04 09:20:03 +0000944- Bug #1196315: fix weakref.WeakValueDictionary constructor.

948
Skip Montanaro174dd222005-05-14 20:54:16 +0000949- Patch #1120353: The xmlrpclib module provides better, more transparent,

951 to True, applications shouldn't have to fiddle with the DateTime wrapper
952 class at all.
953
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000954- distutils.commands.upload was added to support uploading distribution

958 them to PyPI.
959
Raymond Hettinger267b8682005-03-27 10:47:39 +0000960- decimal operator and comparison methods now return NotImplemented
961 instead of raising a TypeError when interacting with other types. This
962 allows other classes to implement __radd__ style methods and have them
963 work as expected.
964
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000965- Bug #1163325: Decimal infinities failed to hash. Attempting to
966 hash a NaN raised an InvalidOperation instead of a TypeError.
967
Tim Petersecc6e6a2005-07-10 22:30:55 +0000968- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1002
Guido van Rossumd0641422005-02-03 15:01:24 +00001003- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1004 disables recursive traversal through instance attributes, which can
1005 be exploited in various ways.
1006
Tim Peterse3547fd2005-12-16 23:13:57 +00001007- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001008 flags on the HTTP listening socket.
1009
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001010- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1011 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1012
Tim Peterse3547fd2005-12-16 23:13:57 +00001013- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001014 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1015
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001016- Bug #1110478: Revert os.environ.update to do putenv again.
1017
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001018- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1019
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001020- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1021
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001022- Enhancements to the csv module:
1023
1024 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001025 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001026 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001027 + Dialect parameter parsing has been re-implemented to improve error
1028 reporting.
1029 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1030 dictates.
1031 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001032 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001033 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001034 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1035 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001036 + reader now allows \r characters to be quoted (previously it only allowed
1037 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001038 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001039 + Dialect classes passed to the module are no longer instantiated by
1040 the module before being parsed (the former validation scheme required
1041 this, but the mechanism was unreliable).
1042 + The dialect registry now contains instances of the internal
1043 C-coded dialect type, rather than references to python objects.
1044 + the internal c-coded dialect type is now immutable.
1045 + register_dialect now accepts the same keyword dialect specifications
1046 as the reader and writer, allowing the user to register dialects
1047 without first creating a dialect class.
1048 + a configurable limit to the size of parsed fields has been added -
1049 previously, an unmatched quote character could result in the entire
1050 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001051 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001052 the parser field size limit (returning the former limit). The initial
1053 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001054 + A line_num attribute has been added to the reader object, which tracks
1055 the number of lines read from the source iterator. This is not
1056 the same as the number of records returned, as records can span
1057 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001058 + reader and writer objects were not being registered with the cyclic-GC.
1059 This has been fixed.
1060
Brett Cannone6539c42005-01-08 02:43:53 +00001061- _DummyThread objects in the threading module now delete self.__block that is
1062 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1063 lock primitives tend to be limited in number and thus should not be wasted on
1064 a _DummyThread object. Fixes bug #1089632.
1065
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001066- The imghdr module now detects Exif files.
1067
Raymond Hettinger6065d322004-12-20 23:51:53 +00001068- StringIO.truncate() now correctly adjusts the size attribute.
1069 (Bug #951915).
1070
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001071- locale.py now uses an updated locale alias table (built using
1072 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1073 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001074 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001075
Raymond Hettinger3557f422004-12-07 12:02:02 +00001076- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1077
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001078- the pickle module no longer accepts the deprecated None option in the
1079 args tuple returned by __reduce__().
1080
Brett Cannon84667c02004-12-07 03:25:18 +00001081- optparse now optionally imports gettext. This allows its use in setup.py.
1082
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001083- the pickle module no longer uses the deprecated bin parameter.
1084
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001085- the shelve module no longer uses the deprecated binary parameter.
1086
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001087- the pstats module no longer uses the deprecated ignore() method.
1088
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001089- the filecmp module no longer uses the deprecated use_statcache argument.
1090
Raymond Hettinger664347b2004-12-04 21:21:53 +00001091- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1092 extended or overridden by subclasses. Formerly, the subclassed method would
1093 be ignored by the rest of the module. (Bug #1078905).
1094
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001095- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001096 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001097
Walter Dörwald36733692004-12-22 12:50:50 +00001098- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1099 once when a size argument is given. This prevents a buffer overflow in the
1100 tokenizer with very long source lines.
1101
Barry Warsaw538561e2006-01-01 21:48:54 +00001102- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1103 immediately after creating the object, without any intervening
1104 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001105
Skip Montanaro05885812005-01-16 20:48:27 +00001106- The reconvert.quote function can now emit triple-quoted strings. The
1107 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001108
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001109- ``UserString.MutableString`` now supports negative indices in
1110 ``__setitem__`` and ``__delitem__``
1111
Greg Ward40407942005-03-05 02:53:17 +00001112- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1113 correctly.
1114
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001115- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1116 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1117 character even if the user has passed a size parameter to get a proper
1118 line ending. Remove the special handling of a "\r\n" that has been split

Walter Dörwalda47d1c02005-08-30 10:23:14 +00001121- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1122 about illegal code points. The codec now supports PEP 293 style error
1123 handlers.
1124
Walter Dörwald78a78b02005-09-01 12:04:29 +00001125- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001126 from the input stream, so that the output is a byte string in the correct
1127 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001128
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001129- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1130 considering it exactly like a '*'.
1131
Walter Dörwald007f8df2005-10-09 19:42:27 +00001132- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1133 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001134
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001135- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1136
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001137- Patch #1413711: Certain patterns of differences were making difflib
1138 touch the recursion limit.
1139
Walter Dörwald58917a62006-03-31 15:26:22 +00001140- Bug #947906: An object oriented interface has been added to the calendar
1141 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001142 called as a script (e.g. via ``python -mcalendar``). Localized month and
1143 weekday names can be ouput (even if an exotic encoding is used) using
1144 special classes that use unicode.

Neal Norwitz602d3392006-03-31 08:21:40 +00001149- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1150 by using -mieee gcc option.
1151

1153
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001154- Build support for Win64-AMD64 was added.
1155
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001156- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1157
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001158- Patch #881820: look for openpty and forkpty also in libbsd.
1159
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001160- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1161 The zlib module is now builtin on Windows.
1162
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001163- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1164
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001165- Bug #1189330: configure did not correctly determine the necessary
1166 value of LINKCC if python was built with GCC 4.0.
1167
Trent Mick8321b422005-07-26 02:29:21 +00001168- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1169 vulnerability in zlib 1.2.1 and 1.2.2.
1170
Brett Cannon08cd5982005-04-24 22:26:38 +00001171- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1172 flags that change binary compatibility. Changes were also made to
1173 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001174 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001175
Bob Ippolitoed233462005-03-29 13:47:59 +00001176- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1177 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1178 no longer exists). This configure patch makes things right.
1179
Martin v. Löwise2713be2005-03-08 15:03:08 +00001180- Bug #1158607: Build with --disable-unicode again.
1181
Brett Cannon46d96232005-02-16 00:07:19 +00001182- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1183 defined. Discovered as a result of not being able to build on OS X.
1184
Brett Cannon516592f2004-12-07 00:42:59 +00001185- setup.py now uses the directories specified in LDFLAGS using the -L option
1186 and in CPPFLAGS using the -I option for adding library and include
1187 directories, respectively, for compiling extension modules against. This has
1188 led to the core being compiled using the values in CPPFLAGS. It also removes
1189 the need for the special-casing of both DarwinPorts and Fink for darwin since
1190 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1191 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1192 Fink, ``-I/opt/local/include`` for DarwinPorts).
1193
Brett Cannon43802422005-02-10 20:48:03 +00001194- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1195 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1196 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1197 Closes bug #1096244. Thanks Gregory Bond.

1200-----
1201
Tim Petersc9d78aa2006-03-26 23:27:58 +00001202- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1203 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1204 is obtained via the ``PyObject_`` family, it must be released via the
1205 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1206 always been officially true, but when Python's small-object allocator was
1207 introduced, an attempt was made to cater to a few extension modules
1208 discovered at the time that obtained memory via ``PyObject_New`` but
1209 released it via ``PyMem_DEL``. It's years later, and if such code still
1210 exists it will fail now (probably with segfaults, but calling wrong
1211 low-level memory management functions can yield many symptoms).
1212
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001213- Added a C API for set and frozenset objects.
1214
Raymond Hettinger66517482004-12-03 11:45:13 +00001215- Removed PyRange_New().
1216
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001217- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1218 mapping argument now. This string is used as a mapping table. Byte values
1219 greater than the length of the string and 0xFFFE are treated as undefined
1220 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001228- Patch #1276356: New resource "urlfetch" is implemented. This enables
1229 even impatient people to run tests that require remote files.
