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
Martin v. Löwis86725192006-05-01 06:28:01 +000070- Calling Tk_Init twice is refused if the first call failed as that
71 may deadlock.
72
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +000073- Patch #1191065: Fix preprocessor problems on systems where recvfrom
74 is a macro.
75
Georg Brandlbbfe4fa2006-04-11 06:47:43 +000076- Bug #1467952: os.listdir() now correctly raises an error if readdir()
77 fails with an error condition.
78
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +000079- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
80
81- Bug #1117761: bsddb.*open() no longer raises an exception when using
82 the cachesize parameter.
83
84- Bug #1149413: bsddb.*open() no longer raises an exception when using
85 a temporary db (file=None) with the 'n' flag to truncate on open.
86
87- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
88 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +000089
Armin Rigoa9017c32006-04-19 11:50:27 +000090- Patch #1062014: AF_UNIX sockets under Linux have a special
91 abstract namespace that is now fully supported.
92
Anthony Baxter51bcb682006-04-05 14:51:42 +000093Library
94-------
95
Georg Brandl1bb62302006-05-03 18:18:32 +000096- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
97 package.
98
Georg Brandl3583cff2006-04-30 18:14:54 +000099- Patch #1472854: make the rlcompleter.Completer class usable on non-
100 UNIX platforms.
101
Georg Brandlfa42bd72006-04-30 07:06:11 +0000102- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
103
Tim Peters711bf302006-04-25 03:31:36 +0000104- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
105 a doctest to be skipped (the code is not run, and the expected output
106 or exception is ignored).
107
Nick Coghlanda2268f2006-04-24 04:37:15 +0000108- Fixed contextlib.nested to cope with exceptions being raised and
109 caught inside exit handlers.
110
Greg Wardab05edc2006-04-23 03:47:58 +0000111- Updated optparse module to Optik 1.5.1 (allow numeric constants in
112 hex, octal, or binary; add ``append_const`` action; keep going if
113 gettext cannot be imported; added ``OptionParser.destroy()`` method;
114 added ``epilog`` for better help generation).
115
Tim Peters21fbd572006-04-21 21:18:10 +0000116- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
117 called from a thread spawned as a side effect of importing a module.
118
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000119- The pydoc module now supports documenting packages contained in
120 .zip or .egg files.
121
122- The pkgutil module now has several new utility functions, such
123 as ``walk_packages()`` to support working with packages that are either
124 in the filesystem or zip files.
125
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000126- The mailbox module can now modify and delete messages from
127 mailboxes, in addition to simply reading them. Thanks to Gregory
128 K. Johnson for writing the code, and to the 2005 Google Summer of
129 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000130
Tim Petersc7605f22006-04-17 21:12:33 +0000131- The ``__del__`` method of class ``local`` in module ``_threading_local``
132 returned before accomplishing any of its intended cleanup.
133
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000134- Patch #790710: Add breakpoint command lists in pdb.
135
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000136- Patch #1063914: Add Tkinter.Misc.clipboard_get().
137
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000138- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
139
Anthony Baxtere29002c2006-04-12 12:07:31 +0000140- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
141 Windows. Bug #1469163.
142
Phillip J. Eby47032112006-04-11 01:07:43 +0000143- The warnings, linecache, inspect, traceback, site, and doctest modules
144 were updated to work correctly with modules imported from zipfiles or
145 via other PEP 302 __loader__ objects.
146
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000147- Patch #1467770: Reduce usage of subprocess._active to processes which
148 the application hasn't waited on.
149
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000150- Patch #1462222: Fix Tix.Grid.
151
Neal Norwitza31bf182006-04-09 03:35:43 +0000152- Fix exception when doing glob.glob('anything*/')
153
Skip Montanaro262fb922006-04-21 02:31:07 +0000154- The pstats.Stats class accepts an optional stream keyword argument to
155 direct output to an alternate file-like object.

158-----
159
Martin v. Löwisb75d43d2006-04-29 12:37:25 +0000160- Patch #1471883: Add --enable-universalsdk.
161
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000162- The Makefile now has a reindent target, which runs reindent.py on
163 the library.
164
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000165- Patch #1470875: Building Python with MS Free Compiler
166
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000167- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000168
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000169- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
170 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000171 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000172 CXX from --with-cxx-main, see description in README.
173
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000174- Patch #1429775: Link extension modules with the shared libpython.
175
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000176- Fixed a libffi build problem on MIPS systems.

181Tests
182-----
183
Nick Coghlanda2268f2006-04-24 04:37:15 +0000184- test_contextlib now checks contextlib.nested can cope with exceptions
185 being raised and caught inside exit handlers.
186
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000187- test_cmd_line now checks operation of the -m and -c command switches
188
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000189- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
190 it separately and by hand. It also wasn't cleaning up its changes to
191 the current Decimal context.
192
Thomas Woutersabd08882006-04-26 15:53:30 +0000193- regrtest.py now has a -M option to run tests that test the new limits of
194 containers, on 64-bit architectures. Running these tests is only sensible
195 on 64-bit machines with more than two gigabytes of memory. The argument
196 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000204Documentation
205-------------
206
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000207- PEP 343: Added Context Types section to the library reference
208 and attempted to bring other PEP 343 related documentation into
209 line with the implementation and/or python-dev discussions.
210
Tim Peters8dc73d22006-04-24 02:03:16 +0000211- Bug #1337990: clarified that ``doctest`` does not support examples
212 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000215What's New in Python 2.5 alpha 1?
216=================================
217
Anthony Baxterebed3f62006-04-03 15:03:44 +0000218*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000219
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000220Core and builtins
221-----------------
222
Nick Coghlan43832302006-04-23 17:04:07 +0000223- PEP 338: -m command line switch now delegates to runpy.run_module
224 allowing it to support modules in packages and zipfiles
225
Martin v. Löwisc661b882006-04-20 04:54:23 +0000226- On Windows, .DLL is not an accepted file name extension for
227 extension modules anymore; extensions are only found if they
228 end in .PYD.
229
Martin v. Löwisea62d252006-04-03 10:56:49 +0000230- Bug #1421664: sys.stderr.encoding is now set to the same value as
231 sys.stdout.encoding.
232
Neal Norwitz92e212f2006-04-03 04:48:37 +0000233- __import__ accepts keyword arguments.
234
Georg Brandlccadf842006-03-31 18:54:53 +0000235- Patch #1460496: round() now accepts keyword arguments.
236
Anthony Baxter262c00a2006-03-30 10:53:17 +0000237- Fixed bug #1459029 - unicode reprs were double-escaped.
238
Hye-Shik Changd478f342006-03-23 12:32:36 +0000239- Patch #1396919: The system scope threads are reenabled on FreeBSD
240 5.4 and later versions.
241
Neal Norwitze98ccf62006-03-23 05:39:47 +0000242- Bug #1115379: Compiling a Unicode string with an encoding declaration
243 now gives a SyntaxError.
244
Georg Brandlabd1ff82006-03-18 07:59:59 +0000245- Previously, Python code had no easy way to access the contents of a
246 cell object. Now, a ``cell_contents`` attribute has been added
247 (closes patch #1170323).
248
Tim Peterscf79aac2006-03-16 01:14:46 +0000249- Patch #1123430: Python's small-object allocator now returns an arena to
250 the system ``free()`` when all memory within an arena becomes unused
251 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
252 freed. Some applications will see a drop in virtual memory size now,
253 especially long-running applications that, from time to time, temporarily
254 use a large number of small objects. Note that when Python returns an
255 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000256 platform C library will in turn return that memory to the operating system.
257 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000258 appears to be effective at least on Microsoft C and gcc-based systems.
259 Thanks to Evan Jones for hard work and patience.
260
Georg Brandl533ff6f2006-03-08 18:09:27 +0000261- Patch #1434038: property() now uses the getter's docstring if there is
262 no "doc" argument given. This makes it possible to legitimately use
263 property() as a decorator to produce a read-only property.
264
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000265- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
266 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
267 of requiring an int or long in slicing and a few other contexts, enabling
268 other objects (e.g. Numeric Python's integers) to be used as slice indices.
269
Neal Norwitz995acdf2006-03-07 05:01:00 +0000270- Fixed various bugs reported by Coverity's Prevent tool.
271
Brett Cannonbf364092006-03-01 04:25:17 +0000272- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
273 new exception base class, BaseException, which has a new message attribute.
274 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
275 Raising a string exception now raises a DeprecationWarning.
276
Thomas Woutersfb609f42006-02-28 16:37:25 +0000277- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
278 explicitly relative, using 'from .module import name' to mean 'from the same
279 package as this module is in. Imports without dots still default to the
280 old relative-then-absolute, unless 'from __future__ import
281 absolute_import' is used.
282
Brett Cannona7446e32006-02-27 23:39:10 +0000283- Properly check if 'warnings' raises an exception (usually when a filter set
284 to "error" is triggered) when raising a warning for raising string
285 exceptions.
286
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000287- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000288 The name was removed from Include/code.h.
289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000290- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000291
Guido van Rossum1968ad32006-02-25 22:38:04 +0000292- Patch 1433928:
293 - The copy module now "copies" function objects (as atomic objects).
294 - dict.__getitem__ now looks for a __missing__ hook before raising
295 KeyError.
296
Tim Peters84ef21c2006-02-28 20:39:06 +0000297- PEP 343: with statement implemented. Needs ``from __future__ import
298 with_statement``. Use of 'with' as a variable will generate a warning.
299 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000300 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000301 The following objects have __context__ methods:
302 - The built-in file type.
303 - The thread.LockType type.
304 - The following types defined by the threading module:
305 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
306 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000307
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000308- Fix the encodings package codec search function to only search
309 inside its own package. Fixes problem reported in patch #1433198.
310
311 Note: Codec packages should implement and register their own
312 codec search function. PEP 100 has the details.
313
Martin v. Löwis18e16552006-02-15 17:27:45 +0000314- PEP 353: Using ssize_t as the index type.
315
Neal Norwitzfc76d632006-01-10 06:03:13 +0000316- Patch #1400181, fix unicode string formatting to not use the locale.
317 This is how string objects work. u'%f' could use , instead of .
318 for the decimal point. Now both strings and unicode always use periods.
319
Neal Norwitz671b9e32006-01-09 07:07:12 +0000320- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
321 configure would break checking curses.h.
322
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000323- Bug #959576: The pwd module is now builtin. This allows Python to be
324 built on UNIX platforms without $HOME set.
325
Neal Norwitzc10978f2005-12-19 06:07:16 +0000326- Bug #1072182, fix some potential problems if characters are signed.
327
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000328- Bug #889500, fix line number on SyntaxWarning for global declarations.
329
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000330- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
331
Neal Norwitze7214a12005-12-18 05:03:17 +0000332- Support for converting hex strings to floats no longer works.
333 This was not portable. float('0x3') now raises a ValueError.
334
Barry Warsaw2a38a862005-12-18 01:27:35 +0000335- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000336 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000337 is now displayed in interactive prompt banner.
338
Georg Brandlfa166682005-12-17 21:45:17 +0000339- Implementation of PEP 341 - Unification of try/except and try/finally.
340 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000341 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000342
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000343- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
344 now encodes backslash correctly.
345
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000346- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
347
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000348- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000349 and long longs.
350
Neal Norwitz67715f02005-11-09 06:59:35 +0000351- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000352 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000353 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000354
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000355- Replaced most Unicode charmap codecs with new ones using the
356 new Unicode translate string feature in the builtin charmap
357 codec; the codecs were created from the mapping tables available
358 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
359 encodings now include a mapping for the Apple logo)
360
Tim Peterse3547fd2005-12-16 23:13:57 +0000361- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000362
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000363- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000364
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000365- A new AST parser implementation was completed. The abstract
366 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000367 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000368
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000369- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000370 The following code now raises a SyntaxError: foo(a = i for i in range(10))
371
Neal Norwitz708e51a2005-10-03 04:48:15 +0000372- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
373
Neal Norwitz11bd1192005-10-03 00:54:56 +0000374- SF Bug #887946: fix segfault when redirecting stdin from a directory.
375 Provide a warning when a directory is passed on the command line.
376
Neal Norwitz40d37812005-10-02 01:48:49 +0000377- Fix segfault with invalid coding.
378
379- SF bug #772896: unknown encoding results in MemoryError.
380
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000381- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000382 supported a __len__() method which evaluated to False when the iterator
383 was empty.
384
Guido van Rossum630db602005-09-20 18:49:54 +0000385- On 64-bit platforms, when __len__() returns a value that cannot be
386 represented as a C int, raise OverflowError.
387
Skip Montanarof8948ca2005-09-19 03:54:46 +0000388- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000389 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000390
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000391- SF bug #893549: parsing keyword arguments was broken with a few format
392 codes.
393
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000394- Changes donated by Elemental Security to make it work on AIX 5.3
395 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
396 bug #105470: test_pwd fails on 64bit system (Opteron).
397
Guido van Rossum539c6622005-09-14 17:49:54 +0000398- Changes donated by Elemental Security to make it work on HP-UX 11 on
399 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
400
Georg Brandl4550b8d2005-08-26 06:43:52 +0000401- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000402 (fixes bug #1119418).
403
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000404- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
405
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000406- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
407 exceptions that cause a function to exit.
408
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000409- The implementation of set() and frozenset() was revised to use its
410 own internal data structure. Memory consumption is reduced by 1/3
411 and there are modest speed-ups as well. The API is unchanged.
412
Tim Petersde7990b2005-07-17 23:45:23 +0000413- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
414
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000415- SF bug #1229429: PyObject_CallMethod failed to decrement some
416 reference counts in some error exit cases.
417
Tim Petersecc6e6a2005-07-10 22:30:55 +0000418- SF bug #1185883: Python's small-object memory allocator took over
419 a block managed by the platform C library whenever a realloc specified
420 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000421 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000422 portable way to copy data from the C-managed block into Python's
423 small-object space without risking a memory fault. Python's small-object
424 realloc now leaves such blocks under the control of the platform C
425 realloc.
426
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000427- SF bug #1232517: An overflow error was not detected properly when
428 attempting to convert a large float to an int in os.utime().
429
Raymond Hettinger3296e692005-06-29 23:29:56 +0000430- SF bug #1224347: hex longs now print with lowercase letters just
431 like their int counterparts.
432
Michael W. Hudson188d4362005-06-20 16:52:57 +0000433- SF bug #1163563: the original fix for bug #1010677 ("thread Module
434 Breaks PyGILState_Ensure()") broke badly in the case of multiple
435 interpreter states; back out that fix and do a better job (see
436 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
437 for a longer write-up of the problem).
438
Michael W. Hudsondf888462005-06-03 14:41:55 +0000439- SF patch #1180995: marshal now uses a binary format by default when
440 serializing floats.
441
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000442- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
443 the routines that promise to produce IEEE 754 binary representations
444 of floats now simply copy bytes around.
445
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000446- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
447 278.
448
Brett Cannonc3647ac2005-04-26 03:45:26 +0000449- patch #1109424: int, long, float, complex, and unicode now check for the
450 proper magic slot for type conversions when subclassed. Previously the
451 magic slot was ignored during conversion. Semantics now match the way
452 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000453 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000454 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000455 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000456
Barry Warsawc8d907c2005-04-19 23:43:40 +0000457- Descriptors defined in C with a PyGetSetDef structure, where the setter is
458 NULL, now raise an AttributeError when attempting to set or delete the
459 attribute. Previously a TypeError was raised, but this was inconsistent
460 with the equivalent pure-Python implementation.
461
Michael W. Hudson774479c2005-04-18 08:46:17 +0000462- It is now safe to call PyGILState_Release() before
463 PyEval_InitThreads() (note that if there is reason to believe there
464 are multiple threads around you still must call PyEval_InitThreads()
465 before using the Python API; this fix is for extension modules that
466 have no way of knowing if Python is multi-threaded yet).
467
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000468- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
469 disabled caused a crash.
470
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000471- Bug #1165306: instancemethod_new allowed the creation of a method
472 with im_class == im_self == NULL, which caused a crash when called.
473
Tim Petersecc6e6a2005-07-10 22:30:55 +0000474- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000475 fixes the crash seen in bug #1165761
476
Raymond Hettinger96229b12005-03-11 06:49:40 +0000477- Added two new builtins, any() and all().
478
Brett Cannon409d8f22005-03-05 06:47:57 +0000479- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000480 (e.g., ``class C(): pass`` is no longer a syntax error).
481 Patch #1176012 added support to the 'parser' module and 'compiler' package
482 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000483
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000484- Patch #1115086: Support PY_LONGLONG in structmember.
485
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000486- Bug #1155938: new style classes did not check that __init__() was
487 returning None.
488
Tim Petersecc6e6a2005-07-10 22:30:55 +0000489- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000490 ('\') with a specific error message.
491
Martin v. Löwisff232d72005-03-03 09:24:38 +0000492- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
493
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000494- Bug #1124295: the __name__ attribute of file objects was
495 inadvertently made inaccessible in restricted mode.
496
Tim Petersecc6e6a2005-07-10 22:30:55 +0000497- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000498 an ferror() call.
499
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000500- min() and max() now support key= arguments with the same meaning as in
501 list.sort().
502
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000503- The peephole optimizer now performs simple constant folding in expressions:
504 (2+3) --> (5).
505
Raymond Hettingera422c342005-01-11 03:03:27 +0000506- set and frozenset objects can now be marshalled. SF #1098985.
507
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000508- Bug #1077106: Poor argument checking could cause memory corruption
509 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000510
Jeremy Hyltonab630502005-02-04 18:44:06 +0000511- The parser did not complain about future statements in illegal
512 positions. It once again reports a syntax error if a future
513 statement occurs after anything other than a doc string.
514
Neil Schemenauercf52c072005-08-12 17:34:58 +0000515- Change the %s format specifier for str objects so that it returns a
516 unicode instance if the argument is not an instance of basestring and
517 calling __str__ on the argument returns a unicode instance.
518
Tim Petersf4e69282006-02-27 17:15:31 +0000519- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
520 current thread state when the auto-GIL-state machinery knows about
521 it (since the thread state is being deleted, continuing to remember it
522 can't help, but can hurt if another thread happens to get created with
523 the same thread id).
524
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000525Extension Modules
526-----------------
527
Georg Brandl43f08a82006-03-31 18:01:16 +0000528- Patch #1380952: fix SSL objects timing out on consecutive read()s
529
Neal Norwitz05a45592006-03-20 06:30:08 +0000530- Patch #1309579: wait3 and wait4 were added to the posix module.
531
Anthony Baxterfa869072006-03-20 05:21:58 +0000532- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
533 In addition, the existing ulaw code was updated.
534
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000535- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000536 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000537
Neal Norwitz10be10c2006-03-16 06:50:13 +0000538- Everything under lib-old was removed. This includes the following modules:
539 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000540 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000541 util, whatsound, whrandom, zmod
542
543- The following modules were removed: regsub, reconvert, regex, regex_syntax.
544
545- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000546 is deprecated. The undocumented re.engine variable no longer exists.
547
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000548- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
549 SS2 (single-shift 2) escape sequences correctly.
550
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000551- The unicodedata module was updated to the 4.1 version of the Unicode
552 database. The 3.2 version is still available as unicodedata.db_3_2_0
553 for applications that require this specific version (such as IDNA).
554
Neal Norwitzb62c4332006-03-04 18:35:47 +0000555- The timing module is no longer built by default. It was deprecated
556 in PEP 4 in Python 2.0 or earlier.
557
Guido van Rossum1968ad32006-02-25 22:38:04 +0000558- Patch 1433928: Added a new type, defaultdict, to the collections module.
559 This uses the new __missing__ hook behavior added to dict (see above).
560
Georg Brandldbd83392006-02-20 09:42:33 +0000561- Bug #854823: socketmodule now builds on Sun platforms even when
562 INET_ADDRSTRLEN is not defined.
563
Georg Brandlf4f44152006-02-18 22:29:33 +0000564- Patch #1393157: os.startfile() now has an optional argument to specify
565 a "command verb" to invoke on the file.
566
Neal Norwitz082b2df2006-02-07 07:04:46 +0000567- Bug #876637, prevent stack corruption when socket descriptor
568 is larger than FD_SETSIZE.
569
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000570- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
571 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
572 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
573
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000574- Patch #1422385: The nis module now supports access to domains other
575 than the system default domain.
576
Martin v. Löwis14694662006-02-03 12:54:16 +0000577- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
578 are reported, the limit on path name lengths is removed, and stat reports

713-------
714
Nick Coghlan43832302006-04-23 17:04:07 +0000715- PEP 338: new module runpy defines a run_module function to support
716 executing modules which provide access to source code or a code object
717 via the PEP 302 import mechanisms.
718

Georg Brandl828fdef2006-04-01 08:59:03 +0000730 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000731 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000732 module will not be built.
733
Tim Petersc17976e2006-04-01 00:26:53 +0000734- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
735 aren't officially supported here, and trying to use them will probably
736 raise an exception some day. But dicts have been allowed, and "mostly
737 worked", so support for them won't go away without warning.
738
Georg Brandl338ef7d2006-03-31 18:42:16 +0000739- Bug #1445068: getpass.getpass() can now be given an explicit stream

757
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000758- email 4.0 package now integrated. This is largely the same as the email 3.0
759 package that was included in Python 2.3, except that PEP 8 module names are
760 now used (e.g. mail.message instead of email.Message). The MIME classes
761 have been moved to a subpackage (e.g. email.mime.text instead of
762 email.MIMEText). The old names are still supported for now. Several
763 deprecated Message methods have been removed and lots of bugs have been
764 fixed. More details can be found in the email package documentation.
765
Walter Dörwald40108c92006-03-27 08:15:44 +0000766- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
767 (a subclass of tuple) that provides incremental decoders and encoders
768 (a way to use stateful codecs without the stream API). Python functions
769 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
770 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
771 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000772
Walter Dörwald067db482006-03-15 22:17:27 +0000773- Patch #1359365: Calling next() on a closed StringIO.String object raises
774 a ValueError instead of a StopIteration now (like file and cString.String do).
775 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
776 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000777

855 "The consensus of researchers in this area (at least as
856 expressed at the NIST Hash Function Workshop 10/31/05),
857 is that SHA-256 is a good choice for the time being, but
858 that research should continue, and other alternatives may
859 arise from this research. The larger SHA's also seem OK."

954 Bug #1224621.
955
Raymond Hettinger68c04532005-06-10 11:05:19 +0000956- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000957 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +0000958 the generate_tokens() function now accepts a callable argument that

969 class at all.
970
Martin v. Löwis55f1bb82005-03-21 20:56:35 +0000971- distutils.commands.upload was added to support uploading distribution

975 them to PyPI.
976
Raymond Hettinger267b8682005-03-27 10:47:39 +0000977- decimal operator and comparison methods now return NotImplemented
978 instead of raising a TypeError when interacting with other types. This
979 allows other classes to implement __radd__ style methods and have them
980 work as expected.
981
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +0000982- Bug #1163325: Decimal infinities failed to hash. Attempting to
983 hash a NaN raised an InvalidOperation instead of a TypeError.
984
Tim Petersecc6e6a2005-07-10 22:30:55 +0000985- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1019
Guido van Rossumd0641422005-02-03 15:01:24 +00001020- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1021 disables recursive traversal through instance attributes, which can
1022 be exploited in various ways.
1023
Tim Peterse3547fd2005-12-16 23:13:57 +00001024- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001025 flags on the HTTP listening socket.
1026
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001027- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1028 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1029
Tim Peterse3547fd2005-12-16 23:13:57 +00001030- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001031 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1032
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001033- Bug #1110478: Revert os.environ.update to do putenv again.
1034
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001035- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1036
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001037- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1038
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001039- Enhancements to the csv module:
1040
1041 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001042 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001043 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001044 + Dialect parameter parsing has been re-implemented to improve error
1045 reporting.
1046 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1047 dictates.
1048 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001049 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001050 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001051 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1052 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001053 + reader now allows \r characters to be quoted (previously it only allowed
1054 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001055 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001056 + Dialect classes passed to the module are no longer instantiated by
1057 the module before being parsed (the former validation scheme required
1058 this, but the mechanism was unreliable).
1059 + The dialect registry now contains instances of the internal
1060 C-coded dialect type, rather than references to python objects.
1061 + the internal c-coded dialect type is now immutable.
1062 + register_dialect now accepts the same keyword dialect specifications
1063 as the reader and writer, allowing the user to register dialects
1064 without first creating a dialect class.
1065 + a configurable limit to the size of parsed fields has been added -
1066 previously, an unmatched quote character could result in the entire
1067 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001068 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001069 the parser field size limit (returning the former limit). The initial
1070 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001071 + A line_num attribute has been added to the reader object, which tracks
1072 the number of lines read from the source iterator. This is not
1073 the same as the number of records returned, as records can span
1074 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001075 + reader and writer objects were not being registered with the cyclic-GC.
1076 This has been fixed.
1077
Brett Cannone6539c42005-01-08 02:43:53 +00001078- _DummyThread objects in the threading module now delete self.__block that is
1079 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1080 lock primitives tend to be limited in number and thus should not be wasted on
1081 a _DummyThread object. Fixes bug #1089632.
1082
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001083- The imghdr module now detects Exif files.
1084
Raymond Hettinger6065d322004-12-20 23:51:53 +00001085- StringIO.truncate() now correctly adjusts the size attribute.
1086 (Bug #951915).
1087
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001088- locale.py now uses an updated locale alias table (built using
1089 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1090 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001091 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001092
Raymond Hettinger3557f422004-12-07 12:02:02 +00001093- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1094
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001095- the pickle module no longer accepts the deprecated None option in the
1096 args tuple returned by __reduce__().
1097
Brett Cannon84667c02004-12-07 03:25:18 +00001098- optparse now optionally imports gettext. This allows its use in setup.py.
1099
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001100- the pickle module no longer uses the deprecated bin parameter.
1101
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001102- the shelve module no longer uses the deprecated binary parameter.
1103
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001104- the pstats module no longer uses the deprecated ignore() method.
1105
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001106- the filecmp module no longer uses the deprecated use_statcache argument.
1107
Raymond Hettinger664347b2004-12-04 21:21:53 +00001108- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1109 extended or overridden by subclasses. Formerly, the subclassed method would
1110 be ignored by the rest of the module. (Bug #1078905).
1111
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001112- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001113 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001114
Walter Dörwald36733692004-12-22 12:50:50 +00001115- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1116 once when a size argument is given. This prevents a buffer overflow in the
1117 tokenizer with very long source lines.
1118
Barry Warsaw538561e2006-01-01 21:48:54 +00001119- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1120 immediately after creating the object, without any intervening
1121 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00001123- The reconvert.quote function can now emit triple-quoted strings. The
1124 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001125
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001126- ``UserString.MutableString`` now supports negative indices in
1127 ``__setitem__`` and ``__delitem__``
1128
Greg Ward40407942005-03-05 02:53:17 +00001129- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1130 correctly.
1131
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001132- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1133 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1134 character even if the user has passed a size parameter to get a proper
1135 line ending. Remove the special handling of a "\r\n" that has been split
1136 between two lines.
1137
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001138- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1139 about illegal code points. The codec now supports PEP 293 style error
1140 handlers.
1141
Walter Dörwald78a78b02005-09-01 12:04:29 +00001142- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001143 from the input stream, so that the output is a byte string in the correct
1144 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001145
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001146- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1147 considering it exactly like a '*'.
1148
Walter Dörwald007f8df2005-10-09 19:42:27 +00001149- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1150 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001151
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001152- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1153
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001154- Patch #1413711: Certain patterns of differences were making difflib
1155 touch the recursion limit.
1156
Walter Dörwald58917a62006-03-31 15:26:22 +00001157- Bug #947906: An object oriented interface has been added to the calendar
1158 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001159 called as a script (e.g. via ``python -mcalendar``). Localized month and
1160 weekday names can be ouput (even if an exotic encoding is used) using
1161 special classes that use unicode.

1164-----
1165
Neal Norwitz602d3392006-03-31 08:21:40 +00001166- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1167 by using -mieee gcc option.
1168

1170
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001171- Build support for Win64-AMD64 was added.
1172
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001173- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1174
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001175- Patch #881820: look for openpty and forkpty also in libbsd.
1176
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001177- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1178 The zlib module is now builtin on Windows.
1179
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001180- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1181
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001182- Bug #1189330: configure did not correctly determine the necessary
1183 value of LINKCC if python was built with GCC 4.0.
1184
Trent Mick8321b422005-07-26 02:29:21 +00001185- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1186 vulnerability in zlib 1.2.1 and 1.2.2.
1187
Brett Cannon08cd5982005-04-24 22:26:38 +00001188- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1189 flags that change binary compatibility. Changes were also made to
1190 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001191 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001192
Bob Ippolitoed233462005-03-29 13:47:59 +00001193- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1194 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1195 no longer exists). This configure patch makes things right.
1196
Martin v. Löwise2713be2005-03-08 15:03:08 +00001197- Bug #1158607: Build with --disable-unicode again.
1198
Brett Cannon46d96232005-02-16 00:07:19 +00001199- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1200 defined. Discovered as a result of not being able to build on OS X.
1201
Brett Cannon516592f2004-12-07 00:42:59 +00001202- setup.py now uses the directories specified in LDFLAGS using the -L option
1203 and in CPPFLAGS using the -I option for adding library and include
1204 directories, respectively, for compiling extension modules against. This has
1205 led to the core being compiled using the values in CPPFLAGS. It also removes
1206 the need for the special-casing of both DarwinPorts and Fink for darwin since
1207 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1208 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1209 Fink, ``-I/opt/local/include`` for DarwinPorts).
1210
Brett Cannon43802422005-02-10 20:48:03 +00001211- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1212 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1213 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1214 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001216C API
1217-----
1218
Tim Petersc9d78aa2006-03-26 23:27:58 +00001219- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1220 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1221 is obtained via the ``PyObject_`` family, it must be released via the
1222 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1223 always been officially true, but when Python's small-object allocator was
1224 introduced, an attempt was made to cater to a few extension modules
1225 discovered at the time that obtained memory via ``PyObject_New`` but
1226 released it via ``PyMem_DEL``. It's years later, and if such code still
1227 exists it will fail now (probably with segfaults, but calling wrong
1228 low-level memory management functions can yield many symptoms).
1229
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001230- Added a C API for set and frozenset objects.
1231
Raymond Hettinger66517482004-12-03 11:45:13 +00001232- Removed PyRange_New().
1233
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001234- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1235 mapping argument now. This string is used as a mapping table. Byte values
1236 greater than the length of the string and 0xFFFE are treated as undefined
1237 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001243- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001245- Patch #1276356: New resource "urlfetch" is implemented. This enables
1246 even impatient people to run tests that require remote files.
