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
Martin v. Löwis77736712006-05-04 05:51:03 +000015- Patch #1475845: Raise IndentationError for unexpected indent.
16
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000017- Patch #1479181: split open() and file() from being aliases for each other.
18
Thomas Heller1b046642006-04-18 18:51:06 +000019- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
20 by converting these apis from macros into exported functions again:
21
22 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
23 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
24 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
25 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
26 PyRun_String Py_CompileString
27
Martin v. Löwis45294a92006-04-18 06:24:08 +000028- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
29
Martin v. Löwis19ab6c92006-04-16 18:55:50 +000030- All uses of PyStructSequence_InitType have been changed to initialize
31 the type objects only once, even if the interpreter is initialized
32 multiple times.
33
Neal Norwitz61546162006-04-14 05:20:28 +000034- Bug #1454485, array.array('u') could crash the interpreter. This was
35 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
36 to unicode when it didn't make sense. 'u#' now requires a unicode string.
37
38- Py_UNICODE is unsigned. It was always documented as unsigned, but
39 due to a bug had a signed value in previous versions.
40
Tim Peters3a5e8b12006-04-11 01:44:07 +000041- Patch #837242: ``id()`` of any Python object always gives a positive
42 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
43 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +000044 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +000045 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +000046
Tim Peters3a5e8b12006-04-11 01:44:07 +000047 def __hash__(self):
48 return id(self) # WRONG
49
50 because a hash result must be a (short) Python int but it was always
51 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +000052 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +000053 was always usable as a hash value before this patch. That's no longer
54 necessarily so.
55
56- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +000057 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +000058 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +000059 #1454844)
60
Phillip J. Eby51dd7d92006-04-11 01:21:31 +000061- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
62 involving generators that have paused outside of any ``try`` or ``with``
63 blocks. (In 2.5a1, a paused generator that was part of a reference
64 cycle could not be garbage collected, regardless of whether it was
65 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +000066
Anthony Baxter51bcb682006-04-05 14:51:42 +000067Extension Modules
68-----------------
69
Tim Petersad2ef332006-05-10 02:43:01 +000070- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
Martin v. Löwisd4e3bb32006-05-06 16:32:54 +000071 As a result, these functions now raise WindowsError instead of OSError.
Martin v. Löwis8e0d4942006-05-04 10:08:42 +000072
Martin v. Löwis86725192006-05-01 06:28:01 +000073- Calling Tk_Init twice is refused if the first call failed as that
74 may deadlock.
75
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000076- Patch #1191065: Fix preprocessor problems on systems where recvfrom
77 is a macro.
78
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000079- Bug #1467952: os.listdir() now correctly raises an error if readdir()
80 fails with an error condition.
81
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000082- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
83
84- Bug #1117761: bsddb.*open() no longer raises an exception when using
85 the cachesize parameter.
86
87- Bug #1149413: bsddb.*open() no longer raises an exception when using
88 a temporary db (file=None) with the 'n' flag to truncate on open.
89
90- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
91 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000092
Armin Rigoa9017c32006-04-19 11:50:27 +000093- Patch #1062014: AF_UNIX sockets under Linux have a special
94 abstract namespace that is now fully supported.
95
Anthony Baxter51bcb682006-04-05 14:51:42 +000096Library
97-------
98
Tim Petersad2ef332006-05-10 02:43:01 +000099- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
100 new flag when ``name`` is already the name of an option flag.
101
Georg Brandl1bb62302006-05-03 18:18:32 +0000102- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
103 package.
104
Georg Brandl3583cff2006-04-30 18:14:54 +0000105- Patch #1472854: make the rlcompleter.Completer class usable on non-
106 UNIX platforms.
107
Georg Brandlfa42bd72006-04-30 07:06:11 +0000108- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
109
Tim Peters711bf302006-04-25 03:31:36 +0000110- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
111 a doctest to be skipped (the code is not run, and the expected output
112 or exception is ignored).
113
Nick Coghlanda2268f2006-04-24 04:37:15 +0000114- Fixed contextlib.nested to cope with exceptions being raised and
115 caught inside exit handlers.
116
Greg Wardab05edc2006-04-23 03:47:58 +0000117- Updated optparse module to Optik 1.5.1 (allow numeric constants in
118 hex, octal, or binary; add ``append_const`` action; keep going if
119 gettext cannot be imported; added ``OptionParser.destroy()`` method;
120 added ``epilog`` for better help generation).
121
Tim Peters21fbd572006-04-21 21:18:10 +0000122- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
123 called from a thread spawned as a side effect of importing a module.
124
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000125- The pydoc module now supports documenting packages contained in
126 .zip or .egg files.
127
128- The pkgutil module now has several new utility functions, such
129 as ``walk_packages()`` to support working with packages that are either
130 in the filesystem or zip files.
131
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000132- The mailbox module can now modify and delete messages from
133 mailboxes, in addition to simply reading them. Thanks to Gregory
134 K. Johnson for writing the code, and to the 2005 Google Summer of
135 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000136
Tim Petersc7605f22006-04-17 21:12:33 +0000137- The ``__del__`` method of class ``local`` in module ``_threading_local``
138 returned before accomplishing any of its intended cleanup.
139
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000140- Patch #790710: Add breakpoint command lists in pdb.
141
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000142- Patch #1063914: Add Tkinter.Misc.clipboard_get().
143
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000144- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
145
Anthony Baxtere29002c2006-04-12 12:07:31 +0000146- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
147 Windows. Bug #1469163.
148
Phillip J. Eby47032112006-04-11 01:07:43 +0000149- The warnings, linecache, inspect, traceback, site, and doctest modules
150 were updated to work correctly with modules imported from zipfiles or
151 via other PEP 302 __loader__ objects.
152
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000153- Patch #1467770: Reduce usage of subprocess._active to processes which
154 the application hasn't waited on.
155
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000156- Patch #1462222: Fix Tix.Grid.
157
Neal Norwitza31bf182006-04-09 03:35:43 +0000158- Fix exception when doing glob.glob('anything*/')
159
Skip Montanaro262fb922006-04-21 02:31:07 +0000160- The pstats.Stats class accepts an optional stream keyword argument to
161 direct output to an alternate file-like object.
162
Anthony Baxter51bcb682006-04-05 14:51:42 +0000163Build
164-----
165
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000166- Patch #1471883: Add --enable-universalsdk.
167
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000168- The Makefile now has a reindent target, which runs reindent.py on
169 the library.
170
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000171- Patch #1470875: Building Python with MS Free Compiler
172
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000173- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000174
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000175- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
176 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000177 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000178 CXX from --with-cxx-main, see description in README.
179
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000180- Patch #1429775: Link extension modules with the shared libpython.
181
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000182- Fixed a libffi build problem on MIPS systems.

186
187Tests
188-----
189
Nick Coghlanda2268f2006-04-24 04:37:15 +0000190- test_contextlib now checks contextlib.nested can cope with exceptions
191 being raised and caught inside exit handlers.
192
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000193- test_cmd_line now checks operation of the -m and -c command switches
194
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000195- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
196 it separately and by hand. It also wasn't cleaning up its changes to
197 the current Decimal context.
198
Thomas Woutersabd08882006-04-26 15:53:30 +0000199- regrtest.py now has a -M option to run tests that test the new limits of
200 containers, on 64-bit architectures. Running these tests is only sensible
201 on 64-bit machines with more than two gigabytes of memory. The argument
202 passed is the maximum amount of memory for the tests to use.
203
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000204Tools
205-----
206
207- Added the Python benchmark suite pybench to the Tools/ directory;
208 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000210Documentation
211-------------
212
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000213- PEP 343: Added Context Types section to the library reference
214 and attempted to bring other PEP 343 related documentation into
215 line with the implementation and/or python-dev discussions.
216
Tim Peters8dc73d22006-04-24 02:03:16 +0000217- Bug #1337990: clarified that ``doctest`` does not support examples
218 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000221What's New in Python 2.5 alpha 1?
222=================================
223
Anthony Baxterebed3f62006-04-03 15:03:44 +0000224*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000225
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000226Core and builtins
227-----------------
228
Nick Coghlan43832302006-04-23 17:04:07 +0000229- PEP 338: -m command line switch now delegates to runpy.run_module
230 allowing it to support modules in packages and zipfiles
231
Martin v. Löwisc661b882006-04-20 04:54:23 +0000232- On Windows, .DLL is not an accepted file name extension for
233 extension modules anymore; extensions are only found if they
234 end in .PYD.
235
Martin v. Löwisea62d252006-04-03 10:56:49 +0000236- Bug #1421664: sys.stderr.encoding is now set to the same value as
237 sys.stdout.encoding.
238
Neal Norwitz92e212f2006-04-03 04:48:37 +0000239- __import__ accepts keyword arguments.
240
Georg Brandlccadf842006-03-31 18:54:53 +0000241- Patch #1460496: round() now accepts keyword arguments.
242
Anthony Baxter262c00a2006-03-30 10:53:17 +0000243- Fixed bug #1459029 - unicode reprs were double-escaped.
244
Hye-Shik Changd478f342006-03-23 12:32:36 +0000245- Patch #1396919: The system scope threads are reenabled on FreeBSD
246 5.4 and later versions.
247
Neal Norwitze98ccf62006-03-23 05:39:47 +0000248- Bug #1115379: Compiling a Unicode string with an encoding declaration
249 now gives a SyntaxError.
250
Georg Brandlabd1ff82006-03-18 07:59:59 +0000251- Previously, Python code had no easy way to access the contents of a
252 cell object. Now, a ``cell_contents`` attribute has been added
253 (closes patch #1170323).
254
Tim Peterscf79aac2006-03-16 01:14:46 +0000255- Patch #1123430: Python's small-object allocator now returns an arena to
256 the system ``free()`` when all memory within an arena becomes unused
257 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
258 freed. Some applications will see a drop in virtual memory size now,
259 especially long-running applications that, from time to time, temporarily
260 use a large number of small objects. Note that when Python returns an
261 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000262 platform C library will in turn return that memory to the operating system.
263 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000264 appears to be effective at least on Microsoft C and gcc-based systems.
265 Thanks to Evan Jones for hard work and patience.
266
Georg Brandl533ff6f2006-03-08 18:09:27 +0000267- Patch #1434038: property() now uses the getter's docstring if there is
268 no "doc" argument given. This makes it possible to legitimately use
269 property() as a decorator to produce a read-only property.
270
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000271- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
272 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
273 of requiring an int or long in slicing and a few other contexts, enabling
274 other objects (e.g. Numeric Python's integers) to be used as slice indices.
275
Neal Norwitz995acdf2006-03-07 05:01:00 +0000276- Fixed various bugs reported by Coverity's Prevent tool.
277
Brett Cannonbf364092006-03-01 04:25:17 +0000278- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
279 new exception base class, BaseException, which has a new message attribute.
280 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
281 Raising a string exception now raises a DeprecationWarning.
282
Thomas Woutersfb609f42006-02-28 16:37:25 +0000283- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
284 explicitly relative, using 'from .module import name' to mean 'from the same
285 package as this module is in. Imports without dots still default to the
286 old relative-then-absolute, unless 'from __future__ import
287 absolute_import' is used.
288
Brett Cannona7446e32006-02-27 23:39:10 +0000289- Properly check if 'warnings' raises an exception (usually when a filter set
290 to "error" is triggered) when raising a warning for raising string
291 exceptions.
292
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000293- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000294 The name was removed from Include/code.h.
295
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000296- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000297
Guido van Rossum1968ad32006-02-25 22:38:04 +0000298- Patch 1433928:
299 - The copy module now "copies" function objects (as atomic objects).
300 - dict.__getitem__ now looks for a __missing__ hook before raising
301 KeyError.
302
Tim Peters84ef21c2006-02-28 20:39:06 +0000303- PEP 343: with statement implemented. Needs ``from __future__ import
304 with_statement``. Use of 'with' as a variable will generate a warning.
305 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000306 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000307 The following objects have __context__ methods:
308 - The built-in file type.
309 - The thread.LockType type.
310 - The following types defined by the threading module:
311 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
312 - The decimal.Context class.

Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000314- Fix the encodings package codec search function to only search
315 inside its own package. Fixes problem reported in patch #1433198.
316
317 Note: Codec packages should implement and register their own
318 codec search function. PEP 100 has the details.
319
Martin v. Löwis18e16552006-02-15 17:27:45 +0000320- PEP 353: Using ssize_t as the index type.
321
Neal Norwitzfc76d632006-01-10 06:03:13 +0000322- Patch #1400181, fix unicode string formatting to not use the locale.
323 This is how string objects work. u'%f' could use , instead of .
324 for the decimal point. Now both strings and unicode always use periods.
325
Neal Norwitz671b9e32006-01-09 07:07:12 +0000326- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
327 configure would break checking curses.h.
328
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000329- Bug #959576: The pwd module is now builtin. This allows Python to be
330 built on UNIX platforms without $HOME set.
331
Neal Norwitzc10978f2005-12-19 06:07:16 +0000332- Bug #1072182, fix some potential problems if characters are signed.
333
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000334- Bug #889500, fix line number on SyntaxWarning for global declarations.
335
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000336- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
337
Neal Norwitze7214a12005-12-18 05:03:17 +0000338- Support for converting hex strings to floats no longer works.
339 This was not portable. float('0x3') now raises a ValueError.
340
Barry Warsaw2a38a862005-12-18 01:27:35 +0000341- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000342 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000343 is now displayed in interactive prompt banner.
344
Georg Brandlfa166682005-12-17 21:45:17 +0000345- Implementation of PEP 341 - Unification of try/except and try/finally.
346 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000347 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000348
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000349- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
350 now encodes backslash correctly.
351
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000352- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
353
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000354- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000355 and long longs.
356
Neal Norwitz67715f02005-11-09 06:59:35 +0000357- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000358 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000359 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000360
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000361- Replaced most Unicode charmap codecs with new ones using the
362 new Unicode translate string feature in the builtin charmap
363 codec; the codecs were created from the mapping tables available
364 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
365 encodings now include a mapping for the Apple logo)
366
Tim Peterse3547fd2005-12-16 23:13:57 +0000367- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000368
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000369- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000370
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000371- A new AST parser implementation was completed. The abstract
372 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000373 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000374
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000375- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000376 The following code now raises a SyntaxError: foo(a = i for i in range(10))
377
Neal Norwitz708e51a2005-10-03 04:48:15 +0000378- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
379
Neal Norwitz11bd1192005-10-03 00:54:56 +0000380- SF Bug #887946: fix segfault when redirecting stdin from a directory.
381 Provide a warning when a directory is passed on the command line.
382
Neal Norwitz40d37812005-10-02 01:48:49 +0000383- Fix segfault with invalid coding.
384
385- SF bug #772896: unknown encoding results in MemoryError.
386
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000387- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000388 supported a __len__() method which evaluated to False when the iterator
389 was empty.
390
Guido van Rossum630db602005-09-20 18:49:54 +0000391- On 64-bit platforms, when __len__() returns a value that cannot be
392 represented as a C int, raise OverflowError.
393
Skip Montanarof8948ca2005-09-19 03:54:46 +0000394- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000395 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000396
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000397- SF bug #893549: parsing keyword arguments was broken with a few format
398 codes.
399
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000400- Changes donated by Elemental Security to make it work on AIX 5.3
401 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
402 bug #105470: test_pwd fails on 64bit system (Opteron).
403
Guido van Rossum539c6622005-09-14 17:49:54 +0000404- Changes donated by Elemental Security to make it work on HP-UX 11 on
405 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
406
Georg Brandl4550b8d2005-08-26 06:43:52 +0000407- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000408 (fixes bug #1119418).
409
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000410- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
411
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000412- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
413 exceptions that cause a function to exit.
414
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000415- The implementation of set() and frozenset() was revised to use its
416 own internal data structure. Memory consumption is reduced by 1/3
417 and there are modest speed-ups as well. The API is unchanged.
418
Tim Petersde7990b2005-07-17 23:45:23 +0000419- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
420
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000421- SF bug #1229429: PyObject_CallMethod failed to decrement some
422 reference counts in some error exit cases.
423
Tim Petersecc6e6a2005-07-10 22:30:55 +0000424- SF bug #1185883: Python's small-object memory allocator took over
425 a block managed by the platform C library whenever a realloc specified
426 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000427 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000428 portable way to copy data from the C-managed block into Python's
429 small-object space without risking a memory fault. Python's small-object
430 realloc now leaves such blocks under the control of the platform C
431 realloc.
432
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000433- SF bug #1232517: An overflow error was not detected properly when
434 attempting to convert a large float to an int in os.utime().
435
Raymond Hettinger3296e692005-06-29 23:29:56 +0000436- SF bug #1224347: hex longs now print with lowercase letters just
437 like their int counterparts.
438
Michael W. Hudson188d4362005-06-20 16:52:57 +0000439- SF bug #1163563: the original fix for bug #1010677 ("thread Module
440 Breaks PyGILState_Ensure()") broke badly in the case of multiple
441 interpreter states; back out that fix and do a better job (see
442 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
443 for a longer write-up of the problem).
444
Michael W. Hudsondf888462005-06-03 14:41:55 +0000445- SF patch #1180995: marshal now uses a binary format by default when
446 serializing floats.
447
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000448- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
449 the routines that promise to produce IEEE 754 binary representations
450 of floats now simply copy bytes around.
451
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000452- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
453 278.
454
Brett Cannonc3647ac2005-04-26 03:45:26 +0000455- patch #1109424: int, long, float, complex, and unicode now check for the
456 proper magic slot for type conversions when subclassed. Previously the
457 magic slot was ignored during conversion. Semantics now match the way
458 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000459 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000460 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000461 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000462
Barry Warsawc8d907c2005-04-19 23:43:40 +0000463- Descriptors defined in C with a PyGetSetDef structure, where the setter is
464 NULL, now raise an AttributeError when attempting to set or delete the
465 attribute. Previously a TypeError was raised, but this was inconsistent
466 with the equivalent pure-Python implementation.
467
Michael W. Hudson774479c2005-04-18 08:46:17 +0000468- It is now safe to call PyGILState_Release() before
469 PyEval_InitThreads() (note that if there is reason to believe there
470 are multiple threads around you still must call PyEval_InitThreads()
471 before using the Python API; this fix is for extension modules that
472 have no way of knowing if Python is multi-threaded yet).
473
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000474- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
475 disabled caused a crash.
476
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000477- Bug #1165306: instancemethod_new allowed the creation of a method
478 with im_class == im_self == NULL, which caused a crash when called.
479
Tim Petersecc6e6a2005-07-10 22:30:55 +0000480- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000481 fixes the crash seen in bug #1165761
482
Raymond Hettinger96229b12005-03-11 06:49:40 +0000483- Added two new builtins, any() and all().
484
Brett Cannon409d8f22005-03-05 06:47:57 +0000485- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000486 (e.g., ``class C(): pass`` is no longer a syntax error).
487 Patch #1176012 added support to the 'parser' module and 'compiler' package
488 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000489
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000490- Patch #1115086: Support PY_LONGLONG in structmember.
491
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000492- Bug #1155938: new style classes did not check that __init__() was
493 returning None.
494
Tim Petersecc6e6a2005-07-10 22:30:55 +0000495- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000496 ('\') with a specific error message.
497
Martin v. Löwisff232d72005-03-03 09:24:38 +0000498- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
499
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000500- Bug #1124295: the __name__ attribute of file objects was
501 inadvertently made inaccessible in restricted mode.
502
Tim Petersecc6e6a2005-07-10 22:30:55 +0000503- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000504 an ferror() call.
505
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000506- min() and max() now support key= arguments with the same meaning as in
507 list.sort().
508
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000509- The peephole optimizer now performs simple constant folding in expressions:
510 (2+3) --> (5).
511
Raymond Hettingera422c342005-01-11 03:03:27 +0000512- set and frozenset objects can now be marshalled. SF #1098985.
513
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000514- Bug #1077106: Poor argument checking could cause memory corruption
515 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000516
Jeremy Hyltonab630502005-02-04 18:44:06 +0000517- The parser did not complain about future statements in illegal
518 positions. It once again reports a syntax error if a future
519 statement occurs after anything other than a doc string.
520
Neil Schemenauercf52c072005-08-12 17:34:58 +0000521- Change the %s format specifier for str objects so that it returns a
522 unicode instance if the argument is not an instance of basestring and
523 calling __str__ on the argument returns a unicode instance.
524
Tim Petersf4e69282006-02-27 17:15:31 +0000525- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
526 current thread state when the auto-GIL-state machinery knows about
527 it (since the thread state is being deleted, continuing to remember it
528 can't help, but can hurt if another thread happens to get created with
529 the same thread id).
530
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000531Extension Modules
532-----------------
533
Georg Brandl43f08a82006-03-31 18:01:16 +0000534- Patch #1380952: fix SSL objects timing out on consecutive read()s
535
Neal Norwitz05a45592006-03-20 06:30:08 +0000536- Patch #1309579: wait3 and wait4 were added to the posix module.
537
Anthony Baxterfa869072006-03-20 05:21:58 +0000538- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
539 In addition, the existing ulaw code was updated.
540
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000541- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000542 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000543
Neal Norwitz10be10c2006-03-16 06:50:13 +0000544- Everything under lib-old was removed. This includes the following modules:
545 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000546 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000547 util, whatsound, whrandom, zmod
548
549- The following modules were removed: regsub, reconvert, regex, regex_syntax.
550
551- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000552 is deprecated. The undocumented re.engine variable no longer exists.
553
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000554- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
555 SS2 (single-shift 2) escape sequences correctly.
556
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000557- The unicodedata module was updated to the 4.1 version of the Unicode
558 database. The 3.2 version is still available as unicodedata.db_3_2_0
559 for applications that require this specific version (such as IDNA).
560
Neal Norwitzb62c4332006-03-04 18:35:47 +0000561- The timing module is no longer built by default. It was deprecated
562 in PEP 4 in Python 2.0 or earlier.
563
Guido van Rossum1968ad32006-02-25 22:38:04 +0000564- Patch 1433928: Added a new type, defaultdict, to the collections module.
565 This uses the new __missing__ hook behavior added to dict (see above).
566
Georg Brandldbd83392006-02-20 09:42:33 +0000567- Bug #854823: socketmodule now builds on Sun platforms even when
568 INET_ADDRSTRLEN is not defined.
569
Georg Brandlf4f44152006-02-18 22:29:33 +0000570- Patch #1393157: os.startfile() now has an optional argument to specify
571 a "command verb" to invoke on the file.
572
Neal Norwitz082b2df2006-02-07 07:04:46 +0000573- Bug #876637, prevent stack corruption when socket descriptor

719-------
720
Nick Coghlan43832302006-04-23 17:04:07 +0000721- PEP 338: new module runpy defines a run_module function to support
722 executing modules which provide access to source code or a code object
723 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +0000736 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000737 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000738 module will not be built.
739
Tim Petersc17976e2006-04-01 00:26:53 +0000740- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
741 aren't officially supported here, and trying to use them will probably
742 raise an exception some day. But dicts have been allowed, and "mostly
743 worked", so support for them won't go away without warning.
744
Georg Brandl338ef7d2006-03-31 18:42:16 +0000745- Bug #1445068: getpass.getpass() can now be given an explicit stream

Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000764- email 4.0 package now integrated. This is largely the same as the email 3.0
765 package that was included in Python 2.3, except that PEP 8 module names are
766 now used (e.g. mail.message instead of email.Message). The MIME classes
767 have been moved to a subpackage (e.g. email.mime.text instead of
768 email.MIMEText). The old names are still supported for now. Several
769 deprecated Message methods have been removed and lots of bugs have been
770 fixed. More details can be found in the email package documentation.
771
Walter Dörwald40108c92006-03-27 08:15:44 +0000772- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
773 (a subclass of tuple) that provides incremental decoders and encoders
774 (a way to use stateful codecs without the stream API). Python functions
775 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
776 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
777 have been added.

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

850
Neal Norwitz338e7862005-12-23 21:27:46 +0000851- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
852 LoadError as documented, instead of IOError. For compatibility,
853 LoadError subclasses IOError.
854
Brett Cannon3cbd0382005-12-16 22:49:23 +0000855- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +0000856 SHA1, 224, 256, 384, and 512. Note that recent developments make the
857 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
858 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
859 Ronald L. Rivest offered this advice for Python:
860
861 "The consensus of researchers in this area (at least as
862 expressed at the NIST Hash Function Workshop 10/31/05),
863 is that SHA-256 is a good choice for the time being, but
864 that research should continue, and other alternatives may
865 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000866
Fredrik Lundh7e0aef02005-12-12 18:54:55 +0000867- Added a subset of Fredrik Lundh's ElementTree package. Available

920 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +0000921 correct line numbers for decoding errors in source code.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +0000959- The tokenize module now detects and reports indentation errors.
960 Bug #1224621.
961
Raymond Hettinger68c04532005-06-10 11:05:19 +0000962- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000963 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000964 the generate_tokens() function now accepts a callable argument that
965 terminates by raising StopIteration.
966
Georg Brandl9166e1a2005-06-04 09:20:03 +0000967- Bug #1196315: fix weakref.WeakValueDictionary constructor.

975 class at all.
976
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000977- distutils.commands.upload was added to support uploading distribution

981 them to PyPI.
982
Raymond Hettinger267b8682005-03-27 10:47:39 +0000983- decimal operator and comparison methods now return NotImplemented
984 instead of raising a TypeError when interacting with other types. This
985 allows other classes to implement __radd__ style methods and have them
986 work as expected.
987
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000988- Bug #1163325: Decimal infinities failed to hash. Attempting to
989 hash a NaN raised an InvalidOperation instead of a TypeError.
990
Tim Petersecc6e6a2005-07-10 22:30:55 +0000991- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1025
Guido van Rossumd0641422005-02-03 15:01:24 +00001026- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1027 disables recursive traversal through instance attributes, which can
1028 be exploited in various ways.
1029
Tim Peterse3547fd2005-12-16 23:13:57 +00001030- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001031 flags on the HTTP listening socket.
1032
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001033- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1034 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1035
Tim Peterse3547fd2005-12-16 23:13:57 +00001036- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001037 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1038

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001041- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1042
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001043- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1044
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001045- Enhancements to the csv module:
1046
1047 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001048 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001049 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001050 + Dialect parameter parsing has been re-implemented to improve error
1051 reporting.
1052 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1053 dictates.
1054 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001055 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001056 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001057 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1058 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001059 + reader now allows \r characters to be quoted (previously it only allowed
1060 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001061 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001062 + Dialect classes passed to the module are no longer instantiated by
1063 the module before being parsed (the former validation scheme required
1064 this, but the mechanism was unreliable).
1065 + The dialect registry now contains instances of the internal
1066 C-coded dialect type, rather than references to python objects.
1067 + the internal c-coded dialect type is now immutable.
1068 + register_dialect now accepts the same keyword dialect specifications
1069 as the reader and writer, allowing the user to register dialects
1070 without first creating a dialect class.
1071 + a configurable limit to the size of parsed fields has been added -
1072 previously, an unmatched quote character could result in the entire
1073 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001074 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001075 the parser field size limit (returning the former limit). The initial
1076 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001077 + A line_num attribute has been added to the reader object, which tracks
1078 the number of lines read from the source iterator. This is not
1079 the same as the number of records returned, as records can span
1080 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001081 + reader and writer objects were not being registered with the cyclic-GC.
1082 This has been fixed.
1083
Brett Cannone6539c42005-01-08 02:43:53 +00001084- _DummyThread objects in the threading module now delete self.__block that is
1085 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1086 lock primitives tend to be limited in number and thus should not be wasted on
1087 a _DummyThread object. Fixes bug #1089632.
1088
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001089- The imghdr module now detects Exif files.
1090
Raymond Hettinger6065d322004-12-20 23:51:53 +00001091- StringIO.truncate() now correctly adjusts the size attribute.
1092 (Bug #951915).
1093
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001094- locale.py now uses an updated locale alias table (built using
1095 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1096 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001097 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001098
Raymond Hettinger3557f422004-12-07 12:02:02 +00001099- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1100
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001101- the pickle module no longer accepts the deprecated None option in the
1102 args tuple returned by __reduce__().
1103
Brett Cannon84667c02004-12-07 03:25:18 +00001104- optparse now optionally imports gettext. This allows its use in setup.py.
1105
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001106- the pickle module no longer uses the deprecated bin parameter.
1107
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001108- the shelve module no longer uses the deprecated binary parameter.
1109
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001110- the pstats module no longer uses the deprecated ignore() method.
1111
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001112- the filecmp module no longer uses the deprecated use_statcache argument.
1113
Raymond Hettinger664347b2004-12-04 21:21:53 +00001114- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1115 extended or overridden by subclasses. Formerly, the subclassed method would
1116 be ignored by the rest of the module. (Bug #1078905).
1117
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001118- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001119 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001120
Walter Dörwald36733692004-12-22 12:50:50 +00001121- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1122 once when a size argument is given. This prevents a buffer overflow in the
1123 tokenizer with very long source lines.
1124
Barry Warsaw538561e2006-01-01 21:48:54 +00001125- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1126 immediately after creating the object, without any intervening
1127 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001128
Skip Montanaro05885812005-01-16 20:48:27 +00001129- The reconvert.quote function can now emit triple-quoted strings. The
1130 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001131
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001132- ``UserString.MutableString`` now supports negative indices in
1133 ``__setitem__`` and ``__delitem__``
1134
Greg Ward40407942005-03-05 02:53:17 +00001135- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1136 correctly.
1137
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001138- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1139 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1140 character even if the user has passed a size parameter to get a proper
1141 line ending. Remove the special handling of a "\r\n" that has been split
1142 between two lines.
1143
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001144- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1145 about illegal code points. The codec now supports PEP 293 style error
1146 handlers.
1147
Walter Dörwald78a78b02005-09-01 12:04:29 +00001148- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001149 from the input stream, so that the output is a byte string in the correct
1150 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001151
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001152- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1153 considering it exactly like a '*'.
1154
Walter Dörwald007f8df2005-10-09 19:42:27 +00001155- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1156 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001157
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001158- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1159
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001160- Patch #1413711: Certain patterns of differences were making difflib
1161 touch the recursion limit.
1162
Walter Dörwald58917a62006-03-31 15:26:22 +00001163- Bug #947906: An object oriented interface has been added to the calendar
1164 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001165 called as a script (e.g. via ``python -mcalendar``). Localized month and
1166 weekday names can be ouput (even if an exotic encoding is used) using
1167 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001168
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001169Build
1170-----
1171
Neal Norwitz602d3392006-03-31 08:21:40 +00001172- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1173 by using -mieee gcc option.
1174

1176
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001177- Build support for Win64-AMD64 was added.
1178
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001179- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1180
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001181- Patch #881820: look for openpty and forkpty also in libbsd.
1182
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001183- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1184 The zlib module is now builtin on Windows.
1185
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001186- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1187
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001188- Bug #1189330: configure did not correctly determine the necessary
1189 value of LINKCC if python was built with GCC 4.0.
1190
Trent Mick8321b422005-07-26 02:29:21 +00001191- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1192 vulnerability in zlib 1.2.1 and 1.2.2.
1193
Brett Cannon08cd5982005-04-24 22:26:38 +00001194- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1195 flags that change binary compatibility. Changes were also made to
1196 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001197 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001198
Bob Ippolitoed233462005-03-29 13:47:59 +00001199- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1200 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1201 no longer exists). This configure patch makes things right.
1202
Martin v. Löwise2713be2005-03-08 15:03:08 +00001203- Bug #1158607: Build with --disable-unicode again.
1204
Brett Cannon46d96232005-02-16 00:07:19 +00001205- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1206 defined. Discovered as a result of not being able to build on OS X.
1207
Brett Cannon516592f2004-12-07 00:42:59 +00001208- setup.py now uses the directories specified in LDFLAGS using the -L option
1209 and in CPPFLAGS using the -I option for adding library and include
1210 directories, respectively, for compiling extension modules against. This has
1211 led to the core being compiled using the values in CPPFLAGS. It also removes
1212 the need for the special-casing of both DarwinPorts and Fink for darwin since
1213 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1214 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1215 Fink, ``-I/opt/local/include`` for DarwinPorts).
1216
Brett Cannon43802422005-02-10 20:48:03 +00001217- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1218 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1219 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1220 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001222C API
1223-----
1224
Tim Petersc9d78aa2006-03-26 23:27:58 +00001225- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1226 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1227 is obtained via the ``PyObject_`` family, it must be released via the
1228 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1229 always been officially true, but when Python's small-object allocator was
1230 introduced, an attempt was made to cater to a few extension modules
1231 discovered at the time that obtained memory via ``PyObject_New`` but
1232 released it via ``PyMem_DEL``. It's years later, and if such code still
1233 exists it will fail now (probably with segfaults, but calling wrong
1234 low-level memory management functions can yield many symptoms).
1235
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001236- Added a C API for set and frozenset objects.
1237
Raymond Hettinger66517482004-12-03 11:45:13 +00001238- Removed PyRange_New().
1239
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001240- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1241 mapping argument now. This string is used as a mapping table. Byte values
1242 greater than the length of the string and 0xFFFE are treated as undefined
1243 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001249- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001250
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001251- Patch #1276356: New resource "urlfetch" is implemented. This enables
1252 even impatient people to run tests that require remote files.
