Neal Norwitz7a5fc282006-05-15 06:48:14 +000010*Release date: XX-MAY-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandl658d5132006-05-23 11:17:21 +000015- PyErr_NewException now accepts a tuple of base classes as its
16 "base" parameter.
17
Richard Jones7c88dcc2006-05-23 10:37:38 +000018- Patch #876206: function call speedup by retaining allocated frame
19 objects.
20
Georg Brandl7b90e162006-05-18 07:01:27 +000021- Bug #1462152: file() now checks more thoroughly for invalid mode
22 strings and removes a possible "U" before passing the mode to the
23 C library function.
24
Neal Norwitz1004a532006-05-15 07:17:23 +000025- Patch #1488312, Fix memory alignment problem on SPARC in unicode
26
Neal Norwitz373f0a72006-05-15 07:04:36 +000027- Bug #1487966: Fix SystemError with conditional expression in assignment
28
Martin v. Löwis879768d2006-05-11 13:28:43 +000029- WindowsError now has two error code attributes: errno, which carries
30 the error values from errno.h, and winerror, which carries the error
31 values from winerror.h. Previous versions put the winerror.h values
32 (from GetLastError()) into the errno attribute.
33
Martin v. Löwis77736712006-05-04 05:51:03 +000034- Patch #1475845: Raise IndentationError for unexpected indent.
35
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000036- Patch #1479181: split open() and file() from being aliases for each other.
37
Neal Norwitz7a5fc282006-05-15 06:48:14 +000038Extension Modules
39-----------------
40
Georg Brandl378d5922006-05-17 14:26:50 +000041- Patch #1490224: time.altzone is now set correctly on Cygwin.
42
Georg Brandl8d3342b2006-05-16 07:38:27 +000043- Patch #1435422: zlib's compress and decompress objects now have a
44 copy() method.
45
Neal Norwitz7a5fc282006-05-15 06:48:14 +000046- On Win32, os.listdir now supports arbitrarily-long Unicode path names
47 (up to the system limit of 32K characters).
48
49- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
50 As a result, these functions now raise WindowsError instead of OSError.
51
52- Calling Tk_Init twice is refused if the first call failed as that
53 may deadlock.
54
55Library
56-------
57
Georg Brandlb89316f2006-05-17 15:51:16 +000058- Patch #1180296: Two new functions were added to the locale module:
59 format_string() to get the effect of "format % items" but locale-aware,
60 and currency() to format a monetary number with currency sign.
61
Georg Brandle3a25832006-05-17 14:56:04 +000062- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

66 tarfiles.
67
Neal Norwitz7a5fc282006-05-15 06:48:14 +000068- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
69 stdout arguments, making it possible to redirect input and output
70 for remote debugging.
71
72- Patch #1484695: Update the tarfile module to version 0.8. This fixes
73 a couple of issues, notably handling of long file names using the
74 GNU LONGNAME extension.
75
76- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
77 new flag when ``name`` is already the name of an option flag.
78
79- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
80 package.
81
82- Patch #1472854: make the rlcompleter.Completer class usable on non-
83 UNIX platforms.

108What's New in Python 2.5 alpha 2?
109=================================
110
111*Release date: 27-APR-2006*
112
113Core and builtins
114-----------------
115
Thomas Heller1b046642006-04-18 18:51:06 +0000116- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
117 by converting these apis from macros into exported functions again:
118
119 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
120 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
121 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
122 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
123 PyRun_String Py_CompileString
124
Martin v. Löwis45294a92006-04-18 06:24:08 +0000125- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
126
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000127- All uses of PyStructSequence_InitType have been changed to initialize
128 the type objects only once, even if the interpreter is initialized
129 multiple times.
130
Neal Norwitz61546162006-04-14 05:20:28 +0000131- Bug #1454485, array.array('u') could crash the interpreter. This was
132 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
133 to unicode when it didn't make sense. 'u#' now requires a unicode string.
134
135- Py_UNICODE is unsigned. It was always documented as unsigned, but
136 due to a bug had a signed value in previous versions.
137
Tim Peters3a5e8b12006-04-11 01:44:07 +0000138- Patch #837242: ``id()`` of any Python object always gives a positive
139 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
140 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000141 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000142 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000143
Tim Peters3a5e8b12006-04-11 01:44:07 +0000144 def __hash__(self):
145 return id(self) # WRONG
146
147 because a hash result must be a (short) Python int but it was always
148 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000149 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000150 was always usable as a hash value before this patch. That's no longer
151 necessarily so.
152
153- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000154 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000155 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000156 #1454844)
157
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000158- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
159 involving generators that have paused outside of any ``try`` or ``with``
160 blocks. (In 2.5a1, a paused generator that was part of a reference
161 cycle could not be garbage collected, regardless of whether it was
162 paused in a ``try`` or ``with`` block.)

166
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000167- Patch #1191065: Fix preprocessor problems on systems where recvfrom
168 is a macro.
169
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000170- Bug #1467952: os.listdir() now correctly raises an error if readdir()
171 fails with an error condition.
172
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000173- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
174
175- Bug #1117761: bsddb.*open() no longer raises an exception when using
176 the cachesize parameter.
177
178- Bug #1149413: bsddb.*open() no longer raises an exception when using
179 a temporary db (file=None) with the 'n' flag to truncate on open.
180
181- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
182 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000183
Armin Rigoa9017c32006-04-19 11:50:27 +0000184- Patch #1062014: AF_UNIX sockets under Linux have a special
185 abstract namespace that is now fully supported.
186
Anthony Baxter51bcb682006-04-05 14:51:42 +0000187Library
188-------
189
Tim Peters711bf302006-04-25 03:31:36 +0000190- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
191 a doctest to be skipped (the code is not run, and the expected output
192 or exception is ignored).
193
Nick Coghlanda2268f2006-04-24 04:37:15 +0000194- Fixed contextlib.nested to cope with exceptions being raised and
195 caught inside exit handlers.
196
Greg Wardab05edc2006-04-23 03:47:58 +0000197- Updated optparse module to Optik 1.5.1 (allow numeric constants in
198 hex, octal, or binary; add ``append_const`` action; keep going if
199 gettext cannot be imported; added ``OptionParser.destroy()`` method;
200 added ``epilog`` for better help generation).
201
Tim Peters21fbd572006-04-21 21:18:10 +0000202- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
203 called from a thread spawned as a side effect of importing a module.
204
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000205- The pydoc module now supports documenting packages contained in
206 .zip or .egg files.
207
208- The pkgutil module now has several new utility functions, such
209 as ``walk_packages()`` to support working with packages that are either
210 in the filesystem or zip files.
211
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000212- The mailbox module can now modify and delete messages from
213 mailboxes, in addition to simply reading them. Thanks to Gregory
214 K. Johnson for writing the code, and to the 2005 Google Summer of
215 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000216
Tim Petersc7605f22006-04-17 21:12:33 +0000217- The ``__del__`` method of class ``local`` in module ``_threading_local``
218 returned before accomplishing any of its intended cleanup.

225
Anthony Baxtere29002c2006-04-12 12:07:31 +0000226- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
227 Windows. Bug #1469163.
228
Phillip J. Eby47032112006-04-11 01:07:43 +0000229- The warnings, linecache, inspect, traceback, site, and doctest modules
230 were updated to work correctly with modules imported from zipfiles or
231 via other PEP 302 __loader__ objects.
232
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000233- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000253- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
254 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000255 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000256 CXX from --with-cxx-main, see description in README.
257

273
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000274- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
275 it separately and by hand. It also wasn't cleaning up its changes to
276 the current Decimal context.
277
Thomas Woutersabd08882006-04-26 15:53:30 +0000278- regrtest.py now has a -M option to run tests that test the new limits of
279 containers, on 64-bit architectures. Running these tests is only sensible
280 on 64-bit machines with more than two gigabytes of memory. The argument
281 passed is the maximum amount of memory for the tests to use.

309
Nick Coghlan43832302006-04-23 17:04:07 +0000310- PEP 338: -m command line switch now delegates to runpy.run_module
311 allowing it to support modules in packages and zipfiles
312
Martin v. Löwisc661b882006-04-20 04:54:23 +0000313- On Windows, .DLL is not an accepted file name extension for
314 extension modules anymore; extensions are only found if they
315 end in .PYD.
316
Martin v. Löwisea62d252006-04-03 10:56:49 +0000317- Bug #1421664: sys.stderr.encoding is now set to the same value as
318 sys.stdout.encoding.
319
Neal Norwitz92e212f2006-04-03 04:48:37 +0000320- __import__ accepts keyword arguments.

331
Georg Brandlabd1ff82006-03-18 07:59:59 +0000332- Previously, Python code had no easy way to access the contents of a
333 cell object. Now, a ``cell_contents`` attribute has been added
334 (closes patch #1170323).
335
Tim Peterscf79aac2006-03-16 01:14:46 +0000336- Patch #1123430: Python's small-object allocator now returns an arena to
337 the system ``free()`` when all memory within an arena becomes unused
338 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
339 freed. Some applications will see a drop in virtual memory size now,
340 especially long-running applications that, from time to time, temporarily
341 use a large number of small objects. Note that when Python returns an
342 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000343 platform C library will in turn return that memory to the operating system.
344 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000345 appears to be effective at least on Microsoft C and gcc-based systems.
346 Thanks to Evan Jones for hard work and patience.
347
Georg Brandl533ff6f2006-03-08 18:09:27 +0000348- Patch #1434038: property() now uses the getter's docstring if there is
349 no "doc" argument given. This makes it possible to legitimately use
350 property() as a decorator to produce a read-only property.
351
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000352- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
353 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
354 of requiring an int or long in slicing and a few other contexts, enabling
355 other objects (e.g. Numeric Python's integers) to be used as slice indices.
356
Neal Norwitz995acdf2006-03-07 05:01:00 +0000357- Fixed various bugs reported by Coverity's Prevent tool.
358
Brett Cannonbf364092006-03-01 04:25:17 +0000359- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
360 new exception base class, BaseException, which has a new message attribute.
361 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
362 Raising a string exception now raises a DeprecationWarning.
363
Thomas Woutersfb609f42006-02-28 16:37:25 +0000364- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
365 explicitly relative, using 'from .module import name' to mean 'from the same
366 package as this module is in. Imports without dots still default to the
367 old relative-then-absolute, unless 'from __future__ import
368 absolute_import' is used.
369
Brett Cannona7446e32006-02-27 23:39:10 +0000370- Properly check if 'warnings' raises an exception (usually when a filter set
371 to "error" is triggered) when raising a warning for raising string
372 exceptions.
373
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000374- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000375 The name was removed from Include/code.h.
376
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000377- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000378
Guido van Rossum1968ad32006-02-25 22:38:04 +0000379- Patch 1433928:
380 - The copy module now "copies" function objects (as atomic objects).
381 - dict.__getitem__ now looks for a __missing__ hook before raising
382 KeyError.
383
Tim Peters84ef21c2006-02-28 20:39:06 +0000384- PEP 343: with statement implemented. Needs ``from __future__ import
385 with_statement``. Use of 'with' as a variable will generate a warning.
386 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000387 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000388 The following objects have __context__ methods:
389 - The built-in file type.
390 - The thread.LockType type.
391 - The following types defined by the threading module:
392 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
393 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000394
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000395- Fix the encodings package codec search function to only search
396 inside its own package. Fixes problem reported in patch #1433198.
397
398 Note: Codec packages should implement and register their own
399 codec search function. PEP 100 has the details.
400
Martin v. Löwis18e16552006-02-15 17:27:45 +0000401- PEP 353: Using ssize_t as the index type.
402
Neal Norwitzfc76d632006-01-10 06:03:13 +0000403- Patch #1400181, fix unicode string formatting to not use the locale.
404 This is how string objects work. u'%f' could use , instead of .
405 for the decimal point. Now both strings and unicode always use periods.
406
Neal Norwitz671b9e32006-01-09 07:07:12 +0000407- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
408 configure would break checking curses.h.
409
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000410- Bug #959576: The pwd module is now builtin. This allows Python to be
411 built on UNIX platforms without $HOME set.
412
Neal Norwitzc10978f2005-12-19 06:07:16 +0000413- Bug #1072182, fix some potential problems if characters are signed.
414
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000415- Bug #889500, fix line number on SyntaxWarning for global declarations.
416
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000417- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
418
Neal Norwitze7214a12005-12-18 05:03:17 +0000419- Support for converting hex strings to floats no longer works.
420 This was not portable. float('0x3') now raises a ValueError.
421
Barry Warsaw2a38a862005-12-18 01:27:35 +0000422- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000423 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000424 is now displayed in interactive prompt banner.
425
Georg Brandlfa166682005-12-17 21:45:17 +0000426- Implementation of PEP 341 - Unification of try/except and try/finally.
427 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000428 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000429
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000430- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
431 now encodes backslash correctly.
432
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000433- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
434
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000435- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000436 and long longs.
437
Neal Norwitz67715f02005-11-09 06:59:35 +0000438- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000439 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000440 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000441
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000442- Replaced most Unicode charmap codecs with new ones using the
443 new Unicode translate string feature in the builtin charmap
444 codec; the codecs were created from the mapping tables available
445 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
446 encodings now include a mapping for the Apple logo)
447
Tim Peterse3547fd2005-12-16 23:13:57 +0000448- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000449
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000450- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000451
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000452- A new AST parser implementation was completed. The abstract
453 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000454 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000455
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000456- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000457 The following code now raises a SyntaxError: foo(a = i for i in range(10))
458
Neal Norwitz708e51a2005-10-03 04:48:15 +0000459- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
460
Neal Norwitz11bd1192005-10-03 00:54:56 +0000461- SF Bug #887946: fix segfault when redirecting stdin from a directory.
462 Provide a warning when a directory is passed on the command line.
463
Neal Norwitz40d37812005-10-02 01:48:49 +0000464- Fix segfault with invalid coding.
465
466- SF bug #772896: unknown encoding results in MemoryError.
467
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000468- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000469 supported a __len__() method which evaluated to False when the iterator
470 was empty.
471
Guido van Rossum630db602005-09-20 18:49:54 +0000472- On 64-bit platforms, when __len__() returns a value that cannot be
473 represented as a C int, raise OverflowError.
474
Skip Montanarof8948ca2005-09-19 03:54:46 +0000475- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000476 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000477
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000478- SF bug #893549: parsing keyword arguments was broken with a few format
479 codes.
480
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000481- Changes donated by Elemental Security to make it work on AIX 5.3
482 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
483 bug #105470: test_pwd fails on 64bit system (Opteron).
484
Guido van Rossum539c6622005-09-14 17:49:54 +0000485- Changes donated by Elemental Security to make it work on HP-UX 11 on
486 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
487
Georg Brandl4550b8d2005-08-26 06:43:52 +0000488- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000489 (fixes bug #1119418).
490
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000491- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
492
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000493- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
494 exceptions that cause a function to exit.
495
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000496- The implementation of set() and frozenset() was revised to use its
497 own internal data structure. Memory consumption is reduced by 1/3
498 and there are modest speed-ups as well. The API is unchanged.
499
Tim Petersde7990b2005-07-17 23:45:23 +0000500- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
501
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000502- SF bug #1229429: PyObject_CallMethod failed to decrement some
503 reference counts in some error exit cases.
504
Tim Petersecc6e6a2005-07-10 22:30:55 +0000505- SF bug #1185883: Python's small-object memory allocator took over
506 a block managed by the platform C library whenever a realloc specified
507 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000508 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000509 portable way to copy data from the C-managed block into Python's
510 small-object space without risking a memory fault. Python's small-object
511 realloc now leaves such blocks under the control of the platform C
512 realloc.
513
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000514- SF bug #1232517: An overflow error was not detected properly when
515 attempting to convert a large float to an int in os.utime().
516
Raymond Hettinger3296e692005-06-29 23:29:56 +0000517- SF bug #1224347: hex longs now print with lowercase letters just
518 like their int counterparts.
519
Michael W. Hudson188d4362005-06-20 16:52:57 +0000520- SF bug #1163563: the original fix for bug #1010677 ("thread Module
521 Breaks PyGILState_Ensure()") broke badly in the case of multiple
522 interpreter states; back out that fix and do a better job (see
523 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
524 for a longer write-up of the problem).
525
Michael W. Hudsondf888462005-06-03 14:41:55 +0000526- SF patch #1180995: marshal now uses a binary format by default when
527 serializing floats.
528
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000529- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
530 the routines that promise to produce IEEE 754 binary representations
531 of floats now simply copy bytes around.
532
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000533- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
534 278.
535
Brett Cannonc3647ac2005-04-26 03:45:26 +0000536- patch #1109424: int, long, float, complex, and unicode now check for the
537 proper magic slot for type conversions when subclassed. Previously the
538 magic slot was ignored during conversion. Semantics now match the way
539 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000540 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000541 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000542 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000543
Barry Warsawc8d907c2005-04-19 23:43:40 +0000544- Descriptors defined in C with a PyGetSetDef structure, where the setter is
545 NULL, now raise an AttributeError when attempting to set or delete the
546 attribute. Previously a TypeError was raised, but this was inconsistent
547 with the equivalent pure-Python implementation.
548
Michael W. Hudson774479c2005-04-18 08:46:17 +0000549- It is now safe to call PyGILState_Release() before
550 PyEval_InitThreads() (note that if there is reason to believe there
551 are multiple threads around you still must call PyEval_InitThreads()
552 before using the Python API; this fix is for extension modules that
553 have no way of knowing if Python is multi-threaded yet).
554
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000555- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
556 disabled caused a crash.
557
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000558- Bug #1165306: instancemethod_new allowed the creation of a method
559 with im_class == im_self == NULL, which caused a crash when called.
560
Tim Petersecc6e6a2005-07-10 22:30:55 +0000561- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000562 fixes the crash seen in bug #1165761
563
Raymond Hettinger96229b12005-03-11 06:49:40 +0000564- Added two new builtins, any() and all().
565
Brett Cannon409d8f22005-03-05 06:47:57 +0000566- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000567 (e.g., ``class C(): pass`` is no longer a syntax error).
568 Patch #1176012 added support to the 'parser' module and 'compiler' package
569 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000570
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000571- Patch #1115086: Support PY_LONGLONG in structmember.
572
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000573- Bug #1155938: new style classes did not check that __init__() was
574 returning None.
575
Tim Petersecc6e6a2005-07-10 22:30:55 +0000576- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000577 ('\') with a specific error message.
578
Martin v. Löwisff232d72005-03-03 09:24:38 +0000579- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
580
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000581- Bug #1124295: the __name__ attribute of file objects was
582 inadvertently made inaccessible in restricted mode.
583
Tim Petersecc6e6a2005-07-10 22:30:55 +0000584- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000585 an ferror() call.
586
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000587- min() and max() now support key= arguments with the same meaning as in
588 list.sort().
589
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000590- The peephole optimizer now performs simple constant folding in expressions:
591 (2+3) --> (5).
592
Raymond Hettingera422c342005-01-11 03:03:27 +0000593- set and frozenset objects can now be marshalled. SF #1098985.
594
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000595- Bug #1077106: Poor argument checking could cause memory corruption
596 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000597
Jeremy Hyltonab630502005-02-04 18:44:06 +0000598- The parser did not complain about future statements in illegal
599 positions. It once again reports a syntax error if a future
600 statement occurs after anything other than a doc string.
601
Neil Schemenauercf52c072005-08-12 17:34:58 +0000602- Change the %s format specifier for str objects so that it returns a
603 unicode instance if the argument is not an instance of basestring and
604 calling __str__ on the argument returns a unicode instance.
605
Tim Petersf4e69282006-02-27 17:15:31 +0000606- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
607 current thread state when the auto-GIL-state machinery knows about
608 it (since the thread state is being deleted, continuing to remember it
609 can't help, but can hurt if another thread happens to get created with
610 the same thread id).

744 for large or negative values.
745

800-------
801
Nick Coghlan43832302006-04-23 17:04:07 +0000802- PEP 338: new module runpy defines a run_module function to support
803 executing modules which provide access to source code or a code object
804 via the PEP 302 import mechanisms.
805
Anthony Baxter93f5b932006-04-03 08:05:07 +0000806- The email module's parsedate_tz function now sets the daylight savings

814 in attribute values.
815
Anthony Baxterc51ee692006-04-01 00:57:31 +0000816- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000817 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000818 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000819 module will not be built.
820
Tim Petersc17976e2006-04-01 00:26:53 +0000821- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
822 aren't officially supported here, and trying to use them will probably
823 raise an exception some day. But dicts have been allowed, and "mostly
824 worked", so support for them won't go away without warning.
825
Georg Brandl338ef7d2006-03-31 18:42:16 +0000826- Bug #1445068: getpass.getpass() can now be given an explicit stream
827 argument to specify where to write the prompt.
828
Georg Brandl22ec80b2006-03-31 18:25:44 +0000829- Patch #1462313, bug #1443328: the pickle modules now can handle classes

844
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000845- email 4.0 package now integrated. This is largely the same as the email 3.0
846 package that was included in Python 2.3, except that PEP 8 module names are
847 now used (e.g. mail.message instead of email.Message). The MIME classes
848 have been moved to a subpackage (e.g. email.mime.text instead of
849 email.MIMEText). The old names are still supported for now. Several
850 deprecated Message methods have been removed and lots of bugs have been
851 fixed. More details can be found in the email package documentation.
852
Walter Dörwald40108c92006-03-27 08:15:44 +0000853- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
854 (a subclass of tuple) that provides incremental decoders and encoders
855 (a way to use stateful codecs without the stream API). Python functions
856 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
857 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
858 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000859
Walter Dörwald067db482006-03-15 22:17:27 +0000860- Patch #1359365: Calling next() on a closed StringIO.String object raises
861 a ValueError instead of a StopIteration now (like file and cString.String do).
862 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
863 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000864
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000865- A regrtest option -w was added to re-run failed tests in verbose mode.

874 command bdist_msi have been added.
875
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000876- PEP 343: new module contextlib.py defines decorator @contextmanager
877 and helpful context managers nested() and closing().
878
Martin v. Löwis415ed932006-02-27 19:56:30 +0000879- The compiler package now supports future imports after the module docstring.
880
Georg Brandl8f7c54e2006-02-20 08:40:38 +0000881- Bug #1413790: zipfile now sanitizes absolute archive names that are

939 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
940 Ronald L. Rivest offered this advice for Python:
941
942 "The consensus of researchers in this area (at least as
943 expressed at the NIST Hash Function Workshop 10/31/05),
944 is that SHA-256 is a good choice for the time being, but
945 that research should continue, and other alternatives may
946 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000947

1128 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001129 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001130 PEP 305.

1135 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001136 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001137 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001138 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields

1141 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001142 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001143 + Dialect classes passed to the module are no longer instantiated by
1144 the module before being parsed (the former validation scheme required
1145 this, but the mechanism was unreliable).
1146 + The dialect registry now contains instances of the internal
1147 C-coded dialect type, rather than references to python objects.
1148 + the internal c-coded dialect type is now immutable.
1149 + register_dialect now accepts the same keyword dialect specifications
1150 as the reader and writer, allowing the user to register dialects
1151 without first creating a dialect class.
1152 + a configurable limit to the size of parsed fields has been added -
1153 previously, an unmatched quote character could result in the entire
1154 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001155 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001156 the parser field size limit (returning the former limit). The initial
1157 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001158 + A line_num attribute has been added to the reader object, which tracks
1159 the number of lines read from the source iterator. This is not
1160 the same as the number of records returned, as records can span
1161 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001162 + reader and writer objects were not being registered with the cyclic-GC.
1163 This has been fixed.
1164
Brett Cannone6539c42005-01-08 02:43:53 +00001165- _DummyThread objects in the threading module now delete self.__block that is
1166 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1167 lock primitives tend to be limited in number and thus should not be wasted on
1168 a _DummyThread object. Fixes bug #1089632.
1169
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001170- The imghdr module now detects Exif files.
1171
Raymond Hettinger6065d322004-12-20 23:51:53 +00001172- StringIO.truncate() now correctly adjusts the size attribute.
1173 (Bug #951915).
1174
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001175- locale.py now uses an updated locale alias table (built using
1176 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1177 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001178 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001179
Raymond Hettinger3557f422004-12-07 12:02:02 +00001180- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1181
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001182- the pickle module no longer accepts the deprecated None option in the
1183 args tuple returned by __reduce__().
1184
Brett Cannon84667c02004-12-07 03:25:18 +00001185- optparse now optionally imports gettext. This allows its use in setup.py.
1186
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001187- the pickle module no longer uses the deprecated bin parameter.
1188
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001189- the shelve module no longer uses the deprecated binary parameter.
1190
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001191- the pstats module no longer uses the deprecated ignore() method.
1192
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001193- the filecmp module no longer uses the deprecated use_statcache argument.
1194
Raymond Hettinger664347b2004-12-04 21:21:53 +00001195- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1196 extended or overridden by subclasses. Formerly, the subclassed method would
1197 be ignored by the rest of the module. (Bug #1078905).
1198
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001199- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001200 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001201
Walter Dörwald36733692004-12-22 12:50:50 +00001202- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1203 once when a size argument is given. This prevents a buffer overflow in the
1204 tokenizer with very long source lines.
1205
Barry Warsaw538561e2006-01-01 21:48:54 +00001206- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1207 immediately after creating the object, without any intervening
1208 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001209
Skip Montanaro05885812005-01-16 20:48:27 +00001210- The reconvert.quote function can now emit triple-quoted strings. The
1211 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001212
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001213- ``UserString.MutableString`` now supports negative indices in
1214 ``__setitem__`` and ``__delitem__``
1215
Greg Ward40407942005-03-05 02:53:17 +00001216- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1217 correctly.
1218
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001219- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1220 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1221 character even if the user has passed a size parameter to get a proper
1222 line ending. Remove the special handling of a "\r\n" that has been split
1223 between two lines.
1224
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001225- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1226 about illegal code points. The codec now supports PEP 293 style error
1227 handlers.
1228
Walter Dörwald78a78b02005-09-01 12:04:29 +00001229- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001230 from the input stream, so that the output is a byte string in the correct
1231 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001232
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001233- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1234 considering it exactly like a '*'.
1235
Walter Dörwald007f8df2005-10-09 19:42:27 +00001236- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1237 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001238
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001239- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1240
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001241- Patch #1413711: Certain patterns of differences were making difflib
1242 touch the recursion limit.
1243
Walter Dörwald58917a62006-03-31 15:26:22 +00001244- Bug #947906: An object oriented interface has been added to the calendar
1245 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001246 called as a script (e.g. via ``python -mcalendar``). Localized month and
1247 weekday names can be ouput (even if an exotic encoding is used) using
1248 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001249
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001250Build
1251-----
1252
Neal Norwitz602d3392006-03-31 08:21:40 +00001253- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1254 by using -mieee gcc option.
1255
Martin v. Löwis86d66262006-02-17 08:40:11 +00001256- Patch #1432345: Make python compile on DragonFly.
1257
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001258- Build support for Win64-AMD64 was added.
1259
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001260- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1261
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001262- Patch #881820: look for openpty and forkpty also in libbsd.
1263
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001264- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1265 The zlib module is now builtin on Windows.
1266
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001267- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1268
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001269- Bug #1189330: configure did not correctly determine the necessary
1270 value of LINKCC if python was built with GCC 4.0.
1271
Trent Mick8321b422005-07-26 02:29:21 +00001272- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1273 vulnerability in zlib 1.2.1 and 1.2.2.
1274
Brett Cannon08cd5982005-04-24 22:26:38 +00001275- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1276 flags that change binary compatibility. Changes were also made to
1277 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001278 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001279
Bob Ippolitoed233462005-03-29 13:47:59 +00001280- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1281 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1282 no longer exists). This configure patch makes things right.
1283
Martin v. Löwise2713be2005-03-08 15:03:08 +00001284- Bug #1158607: Build with --disable-unicode again.
1285
Brett Cannon46d96232005-02-16 00:07:19 +00001286- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1287 defined. Discovered as a result of not being able to build on OS X.
1288
Brett Cannon516592f2004-12-07 00:42:59 +00001289- setup.py now uses the directories specified in LDFLAGS using the -L option
1290 and in CPPFLAGS using the -I option for adding library and include
1291 directories, respectively, for compiling extension modules against. This has
1292 led to the core being compiled using the values in CPPFLAGS. It also removes
1293 the need for the special-casing of both DarwinPorts and Fink for darwin since
1294 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1295 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1296 Fink, ``-I/opt/local/include`` for DarwinPorts).
1297
Brett Cannon43802422005-02-10 20:48:03 +00001298- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1299 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1300 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1301 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001303C API
1304-----
1305
Tim Petersc9d78aa2006-03-26 23:27:58 +00001306- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1307 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1308 is obtained via the ``PyObject_`` family, it must be released via the
1309 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1310 always been officially true, but when Python's small-object allocator was
1311 introduced, an attempt was made to cater to a few extension modules
1312 discovered at the time that obtained memory via ``PyObject_New`` but
1313 released it via ``PyMem_DEL``. It's years later, and if such code still
1314 exists it will fail now (probably with segfaults, but calling wrong
1315 low-level memory management functions can yield many symptoms).
1316
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001317- Added a C API for set and frozenset objects.
1318
Raymond Hettinger66517482004-12-03 11:45:13 +00001319- Removed PyRange_New().
1320
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001321- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1322 mapping argument now. This string is used as a mapping table. Byte values
1323 greater than the length of the string and 0xFFFE are treated as undefined
1324 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001331
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001332- Patch #1276356: New resource "urlfetch" is implemented. This enables
