27 strings and removes a possible "U" before passing the mode to the
28 C library function.
29

33
Martin v. Löwis879768d2006-05-11 13:28:43 +000034- WindowsError now has two error code attributes: errno, which carries
35 the error values from errno.h, and winerror, which carries the error
36 values from winerror.h. Previous versions put the winerror.h values
37 (from GetLastError()) into the errno attribute.
38
Martin v. Löwis77736712006-05-04 05:51:03 +000039- Patch #1475845: Raise IndentationError for unexpected indent.

49 copy() method.
50
Neal Norwitz7a5fc282006-05-15 06:48:14 +000051- On Win32, os.listdir now supports arbitrarily-long Unicode path names
52 (up to the system limit of 32K characters).
53
54- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
55 As a result, these functions now raise WindowsError instead of OSError.
56
57- Calling Tk_Init twice is refused if the first call failed as that
58 may deadlock.
59
60Library
61-------
62
Bob Ippolito7298f272006-05-23 18:43:47 +000063- Patch #1281707: speed up gzip.readline.

74
Neal Norwitz7a5fc282006-05-15 06:48:14 +000075- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
76 stdout arguments, making it possible to redirect input and output
77 for remote debugging.
78
79- Patch #1484695: Update the tarfile module to version 0.8. This fixes
80 a couple of issues, notably handling of long file names using the
81 GNU LONGNAME extension.
82
83- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
84 new flag when ``name`` is already the name of an option flag.
85
86- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler

115What's New in Python 2.5 alpha 2?
116=================================
117
118*Release date: 27-APR-2006*
119
120Core and builtins
121-----------------
122
Thomas Heller1b046642006-04-18 18:51:06 +0000123- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
124 by converting these apis from macros into exported functions again:
125
126 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
127 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
128 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
129 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
130 PyRun_String Py_CompileString
131
Martin v. Löwis45294a92006-04-18 06:24:08 +0000132- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
133
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000134- All uses of PyStructSequence_InitType have been changed to initialize
135 the type objects only once, even if the interpreter is initialized
136 multiple times.
137
Neal Norwitz61546162006-04-14 05:20:28 +0000138- Bug #1454485, array.array('u') could crash the interpreter. This was
139 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
140 to unicode when it didn't make sense. 'u#' now requires a unicode string.
141
142- Py_UNICODE is unsigned. It was always documented as unsigned, but
143 due to a bug had a signed value in previous versions.
144
Tim Peters3a5e8b12006-04-11 01:44:07 +0000145- Patch #837242: ``id()`` of any Python object always gives a positive
146 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
147 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000148 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000149 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000150
Tim Peters3a5e8b12006-04-11 01:44:07 +0000151 def __hash__(self):
152 return id(self) # WRONG
153
154 because a hash result must be a (short) Python int but it was always
155 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000156 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000157 was always usable as a hash value before this patch. That's no longer
158 necessarily so.
159
160- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000161 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000162 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000163 #1454844)
164
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000165- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
166 involving generators that have paused outside of any ``try`` or ``with``
167 blocks. (In 2.5a1, a paused generator that was part of a reference
168 cycle could not be garbage collected, regardless of whether it was
169 paused in a ``try`` or ``with`` block.)

175 is a macro.
176
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000177- Bug #1467952: os.listdir() now correctly raises an error if readdir()
178 fails with an error condition.
179
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000180- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
181
182- Bug #1117761: bsddb.*open() no longer raises an exception when using
183 the cachesize parameter.
184
185- Bug #1149413: bsddb.*open() no longer raises an exception when using
186 a temporary db (file=None) with the 'n' flag to truncate on open.
187
188- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
189 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000190
Armin Rigoa9017c32006-04-19 11:50:27 +0000191- Patch #1062014: AF_UNIX sockets under Linux have a special
192 abstract namespace that is now fully supported.
193
Anthony Baxter51bcb682006-04-05 14:51:42 +0000194Library
195-------
196
Tim Peters711bf302006-04-25 03:31:36 +0000197- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
198 a doctest to be skipped (the code is not run, and the expected output
199 or exception is ignored).
200
Nick Coghlanda2268f2006-04-24 04:37:15 +0000201- Fixed contextlib.nested to cope with exceptions being raised and
202 caught inside exit handlers.
203
Greg Wardab05edc2006-04-23 03:47:58 +0000204- Updated optparse module to Optik 1.5.1 (allow numeric constants in
205 hex, octal, or binary; add ``append_const`` action; keep going if
206 gettext cannot be imported; added ``OptionParser.destroy()`` method;
207 added ``epilog`` for better help generation).
208
Tim Peters21fbd572006-04-21 21:18:10 +0000209- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
210 called from a thread spawned as a side effect of importing a module.
211
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000212- The pydoc module now supports documenting packages contained in
213 .zip or .egg files.
214
215- The pkgutil module now has several new utility functions, such
216 as ``walk_packages()`` to support working with packages that are either
217 in the filesystem or zip files.
218
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000219- The mailbox module can now modify and delete messages from
220 mailboxes, in addition to simply reading them. Thanks to Gregory
221 K. Johnson for writing the code, and to the 2005 Google Summer of
222 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000223
Tim Petersc7605f22006-04-17 21:12:33 +0000224- The ``__del__`` method of class ``local`` in module ``_threading_local``
225 returned before accomplishing any of its intended cleanup.
226

232
Anthony Baxtere29002c2006-04-12 12:07:31 +0000233- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
234 Windows. Bug #1469163.
235
Phillip J. Eby47032112006-04-11 01:07:43 +0000236- The warnings, linecache, inspect, traceback, site, and doctest modules
237 were updated to work correctly with modules imported from zipfiles or
238 via other PEP 302 __loader__ objects.
239
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000240- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000260- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
261 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000262 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000263 CXX from --with-cxx-main, see description in README.
264
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000265- Patch #1429775: Link extension modules with the shared libpython.
266

280
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000281- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
282 it separately and by hand. It also wasn't cleaning up its changes to
283 the current Decimal context.
284
Thomas Woutersabd08882006-04-26 15:53:30 +0000285- regrtest.py now has a -M option to run tests that test the new limits of

Nick Coghlan43832302006-04-23 17:04:07 +0000317- PEP 338: -m command line switch now delegates to runpy.run_module
318 allowing it to support modules in packages and zipfiles
319
Martin v. Löwisc661b882006-04-20 04:54:23 +0000320- On Windows, .DLL is not an accepted file name extension for

337 now gives a SyntaxError.
338
Georg Brandlabd1ff82006-03-18 07:59:59 +0000339- Previously, Python code had no easy way to access the contents of a
340 cell object. Now, a ``cell_contents`` attribute has been added
341 (closes patch #1170323).
342
Tim Peterscf79aac2006-03-16 01:14:46 +0000343- Patch #1123430: Python's small-object allocator now returns an arena to
344 the system ``free()`` when all memory within an arena becomes unused
345 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
346 freed. Some applications will see a drop in virtual memory size now,
347 especially long-running applications that, from time to time, temporarily
348 use a large number of small objects. Note that when Python returns an
349 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000350 platform C library will in turn return that memory to the operating system.
351 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000352 appears to be effective at least on Microsoft C and gcc-based systems.
353 Thanks to Evan Jones for hard work and patience.
354
Georg Brandl533ff6f2006-03-08 18:09:27 +0000355- Patch #1434038: property() now uses the getter's docstring if there is
356 no "doc" argument given. This makes it possible to legitimately use
357 property() as a decorator to produce a read-only property.
358
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000359- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
360 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
361 of requiring an int or long in slicing and a few other contexts, enabling
362 other objects (e.g. Numeric Python's integers) to be used as slice indices.
363
Neal Norwitz995acdf2006-03-07 05:01:00 +0000364- Fixed various bugs reported by Coverity's Prevent tool.
365
Brett Cannonbf364092006-03-01 04:25:17 +0000366- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
367 new exception base class, BaseException, which has a new message attribute.
368 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
369 Raising a string exception now raises a DeprecationWarning.
370
Thomas Woutersfb609f42006-02-28 16:37:25 +0000371- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
372 explicitly relative, using 'from .module import name' to mean 'from the same
373 package as this module is in. Imports without dots still default to the
374 old relative-then-absolute, unless 'from __future__ import
375 absolute_import' is used.
376
Brett Cannona7446e32006-02-27 23:39:10 +0000377- Properly check if 'warnings' raises an exception (usually when a filter set
378 to "error" is triggered) when raising a warning for raising string
379 exceptions.
380
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000381- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000382 The name was removed from Include/code.h.
383
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000384- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000385
Guido van Rossum1968ad32006-02-25 22:38:04 +0000386- Patch 1433928:
387 - The copy module now "copies" function objects (as atomic objects).
388 - dict.__getitem__ now looks for a __missing__ hook before raising
389 KeyError.
390
Tim Peters84ef21c2006-02-28 20:39:06 +0000391- PEP 343: with statement implemented. Needs ``from __future__ import
392 with_statement``. Use of 'with' as a variable will generate a warning.
393 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000394 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000395 The following objects have __context__ methods:
396 - The built-in file type.
397 - The thread.LockType type.
398 - The following types defined by the threading module:
399 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
400 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000401
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000402- Fix the encodings package codec search function to only search
403 inside its own package. Fixes problem reported in patch #1433198.
404
405 Note: Codec packages should implement and register their own
406 codec search function. PEP 100 has the details.
407
Martin v. Löwis18e16552006-02-15 17:27:45 +0000408- PEP 353: Using ssize_t as the index type.
409
Neal Norwitzfc76d632006-01-10 06:03:13 +0000410- Patch #1400181, fix unicode string formatting to not use the locale.
411 This is how string objects work. u'%f' could use , instead of .
412 for the decimal point. Now both strings and unicode always use periods.
413
Neal Norwitz671b9e32006-01-09 07:07:12 +0000414- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
415 configure would break checking curses.h.
416
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000417- Bug #959576: The pwd module is now builtin. This allows Python to be
418 built on UNIX platforms without $HOME set.
419
Neal Norwitzc10978f2005-12-19 06:07:16 +0000420- Bug #1072182, fix some potential problems if characters are signed.
421
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000422- Bug #889500, fix line number on SyntaxWarning for global declarations.
423
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000424- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
425
Neal Norwitze7214a12005-12-18 05:03:17 +0000426- Support for converting hex strings to floats no longer works.
427 This was not portable. float('0x3') now raises a ValueError.
428
Barry Warsaw2a38a862005-12-18 01:27:35 +0000429- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000430 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000431 is now displayed in interactive prompt banner.
432
Georg Brandlfa166682005-12-17 21:45:17 +0000433- Implementation of PEP 341 - Unification of try/except and try/finally.
434 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000435 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000436
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000437- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
438 now encodes backslash correctly.
439
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000440- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
441
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000442- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000443 and long longs.
444
Neal Norwitz67715f02005-11-09 06:59:35 +0000445- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000446 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000447 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000448
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000449- Replaced most Unicode charmap codecs with new ones using the
450 new Unicode translate string feature in the builtin charmap
451 codec; the codecs were created from the mapping tables available
452 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
453 encodings now include a mapping for the Apple logo)
454
Tim Peterse3547fd2005-12-16 23:13:57 +0000455- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000456
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000457- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000458
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000459- A new AST parser implementation was completed. The abstract
460 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000461 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000463- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000464 The following code now raises a SyntaxError: foo(a = i for i in range(10))
465
Neal Norwitz708e51a2005-10-03 04:48:15 +0000466- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
467
Neal Norwitz11bd1192005-10-03 00:54:56 +0000468- SF Bug #887946: fix segfault when redirecting stdin from a directory.
469 Provide a warning when a directory is passed on the command line.
470
Neal Norwitz40d37812005-10-02 01:48:49 +0000471- Fix segfault with invalid coding.
472
473- SF bug #772896: unknown encoding results in MemoryError.
474
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000475- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000476 supported a __len__() method which evaluated to False when the iterator
477 was empty.
478
Guido van Rossum630db602005-09-20 18:49:54 +0000479- On 64-bit platforms, when __len__() returns a value that cannot be
480 represented as a C int, raise OverflowError.
481
Skip Montanarof8948ca2005-09-19 03:54:46 +0000482- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000483 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000484
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000485- SF bug #893549: parsing keyword arguments was broken with a few format
486 codes.
487
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000488- Changes donated by Elemental Security to make it work on AIX 5.3
489 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
490 bug #105470: test_pwd fails on 64bit system (Opteron).
491
Guido van Rossum539c6622005-09-14 17:49:54 +0000492- Changes donated by Elemental Security to make it work on HP-UX 11 on
493 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
494
Georg Brandl4550b8d2005-08-26 06:43:52 +0000495- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000496 (fixes bug #1119418).
497
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000498- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
499
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000500- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
501 exceptions that cause a function to exit.
502
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000503- The implementation of set() and frozenset() was revised to use its
504 own internal data structure. Memory consumption is reduced by 1/3
505 and there are modest speed-ups as well. The API is unchanged.
506
Tim Petersde7990b2005-07-17 23:45:23 +0000507- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
508
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000509- SF bug #1229429: PyObject_CallMethod failed to decrement some
510 reference counts in some error exit cases.
511
Tim Petersecc6e6a2005-07-10 22:30:55 +0000512- SF bug #1185883: Python's small-object memory allocator took over
513 a block managed by the platform C library whenever a realloc specified
514 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000515 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000516 portable way to copy data from the C-managed block into Python's
517 small-object space without risking a memory fault. Python's small-object
518 realloc now leaves such blocks under the control of the platform C
519 realloc.
520
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000521- SF bug #1232517: An overflow error was not detected properly when
522 attempting to convert a large float to an int in os.utime().
523
Raymond Hettinger3296e692005-06-29 23:29:56 +0000524- SF bug #1224347: hex longs now print with lowercase letters just
525 like their int counterparts.
526
Michael W. Hudson188d4362005-06-20 16:52:57 +0000527- SF bug #1163563: the original fix for bug #1010677 ("thread Module
528 Breaks PyGILState_Ensure()") broke badly in the case of multiple
529 interpreter states; back out that fix and do a better job (see
530 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
531 for a longer write-up of the problem).
532
Michael W. Hudsondf888462005-06-03 14:41:55 +0000533- SF patch #1180995: marshal now uses a binary format by default when
534 serializing floats.
535
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000536- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
537 the routines that promise to produce IEEE 754 binary representations
538 of floats now simply copy bytes around.
539
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000540- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
541 278.
542
Brett Cannonc3647ac2005-04-26 03:45:26 +0000543- patch #1109424: int, long, float, complex, and unicode now check for the
544 proper magic slot for type conversions when subclassed. Previously the
545 magic slot was ignored during conversion. Semantics now match the way
546 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000547 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000548 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000549 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000550
Barry Warsawc8d907c2005-04-19 23:43:40 +0000551- Descriptors defined in C with a PyGetSetDef structure, where the setter is
552 NULL, now raise an AttributeError when attempting to set or delete the
553 attribute. Previously a TypeError was raised, but this was inconsistent
554 with the equivalent pure-Python implementation.
555
Michael W. Hudson774479c2005-04-18 08:46:17 +0000556- It is now safe to call PyGILState_Release() before
557 PyEval_InitThreads() (note that if there is reason to believe there
558 are multiple threads around you still must call PyEval_InitThreads()
559 before using the Python API; this fix is for extension modules that
560 have no way of knowing if Python is multi-threaded yet).
561
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000562- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
563 disabled caused a crash.
564
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000565- Bug #1165306: instancemethod_new allowed the creation of a method
566 with im_class == im_self == NULL, which caused a crash when called.
567
Tim Petersecc6e6a2005-07-10 22:30:55 +0000568- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000569 fixes the crash seen in bug #1165761
570
Raymond Hettinger96229b12005-03-11 06:49:40 +0000571- Added two new builtins, any() and all().
572
Brett Cannon409d8f22005-03-05 06:47:57 +0000573- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000574 (e.g., ``class C(): pass`` is no longer a syntax error).
575 Patch #1176012 added support to the 'parser' module and 'compiler' package
576 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000577
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000578- Patch #1115086: Support PY_LONGLONG in structmember.
579
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000580- Bug #1155938: new style classes did not check that __init__() was
581 returning None.
582
Tim Petersecc6e6a2005-07-10 22:30:55 +0000583- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000584 ('\') with a specific error message.
585
Martin v. Löwisff232d72005-03-03 09:24:38 +0000586- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
587
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000588- Bug #1124295: the __name__ attribute of file objects was
589 inadvertently made inaccessible in restricted mode.
590
Tim Petersecc6e6a2005-07-10 22:30:55 +0000591- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000592 an ferror() call.
593
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000594- min() and max() now support key= arguments with the same meaning as in
595 list.sort().
596
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000597- The peephole optimizer now performs simple constant folding in expressions:
598 (2+3) --> (5).
599
Raymond Hettingera422c342005-01-11 03:03:27 +0000600- set and frozenset objects can now be marshalled. SF #1098985.
601
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000602- Bug #1077106: Poor argument checking could cause memory corruption
603 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000604
Jeremy Hyltonab630502005-02-04 18:44:06 +0000605- The parser did not complain about future statements in illegal
606 positions. It once again reports a syntax error if a future
607 statement occurs after anything other than a doc string.
608
Neil Schemenauercf52c072005-08-12 17:34:58 +0000609- Change the %s format specifier for str objects so that it returns a
610 unicode instance if the argument is not an instance of basestring and
611 calling __str__ on the argument returns a unicode instance.
612
Tim Petersf4e69282006-02-27 17:15:31 +0000613- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
614 current thread state when the auto-GIL-state machinery knows about
615 it (since the thread state is being deleted, continuing to remember it
616 can't help, but can hurt if another thread happens to get created with
617 the same thread id).

750 the request code argument, which results in more C-like behaviour
751 for large or negative values.
752
Tim Petersecc6e6a2005-07-10 22:30:55 +0000753- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlaf410b52005-07-08 22:26:13 +0000755
Georg Brandl6b95f1d2005-06-03 19:47:00 +0000756- Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.

Raymond Hettingerb2594052004-12-05 09:25:51 +0000796- itertools.islice() now accepts None for the start and step arguments.
797 This allows islice() to work more readily with slices:

807-------
808
Nick Coghlan43832302006-04-23 17:04:07 +0000809- PEP 338: new module runpy defines a run_module function to support
810 executing modules which provide access to source code or a code object
811 via the PEP 302 import mechanisms.
812
Anthony Baxter93f5b932006-04-03 08:05:07 +0000813- The email module's parsedate_tz function now sets the daylight savings
814 flag to -1 (unknown) since it can't tell from the date whether it should
815 be set.
816
Fred Drakead5177c2006-04-01 22:14:43 +0000817- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results

821 in attribute values.
822
Anthony Baxterc51ee692006-04-01 00:57:31 +0000823- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000824 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000825 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000826 module will not be built.
827
Tim Petersc17976e2006-04-01 00:26:53 +0000828- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
829 aren't officially supported here, and trying to use them will probably
830 raise an exception some day. But dicts have been allowed, and "mostly
831 worked", so support for them won't go away without warning.
832
Georg Brandl338ef7d2006-03-31 18:42:16 +0000833- Bug #1445068: getpass.getpass() can now be given an explicit stream
834 argument to specify where to write the prompt.
835
Georg Brandl22ec80b2006-03-31 18:25:44 +0000836- Patch #1462313, bug #1443328: the pickle modules now can handle classes

851
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000852- email 4.0 package now integrated. This is largely the same as the email 3.0
853 package that was included in Python 2.3, except that PEP 8 module names are
854 now used (e.g. mail.message instead of email.Message). The MIME classes
855 have been moved to a subpackage (e.g. email.mime.text instead of
856 email.MIMEText). The old names are still supported for now. Several
857 deprecated Message methods have been removed and lots of bugs have been
858 fixed. More details can be found in the email package documentation.
859
Walter Dörwald40108c92006-03-27 08:15:44 +0000860- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
861 (a subclass of tuple) that provides incremental decoders and encoders
862 (a way to use stateful codecs without the stream API). Python functions
863 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
864 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
865 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000866
Walter Dörwald067db482006-03-15 22:17:27 +0000867- Patch #1359365: Calling next() on a closed StringIO.String object raises
868 a ValueError instead of a StopIteration now (like file and cString.String do).
869 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
870 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000871
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000872- A regrtest option -w was added to re-run failed tests in verbose mode.

878 grew an optional 'generation' argument.
879
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000880- A library msilib to generate Windows Installer files, and a distutils
881 command bdist_msi have been added.
882
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000883- PEP 343: new module contextlib.py defines decorator @contextmanager
884 and helpful context managers nested() and closing().
885

946 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
947 Ronald L. Rivest offered this advice for Python:
948
949 "The consensus of researchers in this area (at least as
950 expressed at the NIST Hash Function Workshop 10/31/05),
951 is that SHA-256 is a good choice for the time being, but
952 that research should continue, and other alternatives may
953 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +0000954

1142 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001143 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001144 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001145 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1146 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001147 + reader now allows \r characters to be quoted (previously it only allowed
1148 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001149 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001150 + Dialect classes passed to the module are no longer instantiated by
1151 the module before being parsed (the former validation scheme required
1152 this, but the mechanism was unreliable).
1153 + The dialect registry now contains instances of the internal
1154 C-coded dialect type, rather than references to python objects.
1155 + the internal c-coded dialect type is now immutable.
1156 + register_dialect now accepts the same keyword dialect specifications
1157 as the reader and writer, allowing the user to register dialects
1158 without first creating a dialect class.
1159 + a configurable limit to the size of parsed fields has been added -
1160 previously, an unmatched quote character could result in the entire
1161 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001162 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001163 the parser field size limit (returning the former limit). The initial
1164 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001165 + A line_num attribute has been added to the reader object, which tracks
1166 the number of lines read from the source iterator. This is not
1167 the same as the number of records returned, as records can span
1168 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001169 + reader and writer objects were not being registered with the cyclic-GC.
1170 This has been fixed.
1171
Brett Cannone6539c42005-01-08 02:43:53 +00001172- _DummyThread objects in the threading module now delete self.__block that is
1173 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1174 lock primitives tend to be limited in number and thus should not be wasted on
1175 a _DummyThread object. Fixes bug #1089632.
1176
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001177- The imghdr module now detects Exif files.
1178
Raymond Hettinger6065d322004-12-20 23:51:53 +00001179- StringIO.truncate() now correctly adjusts the size attribute.
1180 (Bug #951915).
1181
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001182- locale.py now uses an updated locale alias table (built using
1183 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1184 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001185 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001186
Raymond Hettinger3557f422004-12-07 12:02:02 +00001187- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1188
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001189- the pickle module no longer accepts the deprecated None option in the
1190 args tuple returned by __reduce__().
1191
Brett Cannon84667c02004-12-07 03:25:18 +00001192- optparse now optionally imports gettext. This allows its use in setup.py.
1193
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001194- the pickle module no longer uses the deprecated bin parameter.
1195
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001196- the shelve module no longer uses the deprecated binary parameter.
1197
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001198- the pstats module no longer uses the deprecated ignore() method.
1199
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001200- the filecmp module no longer uses the deprecated use_statcache argument.
1201
Raymond Hettinger664347b2004-12-04 21:21:53 +00001202- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1203 extended or overridden by subclasses. Formerly, the subclassed method would
1204 be ignored by the rest of the module. (Bug #1078905).
1205
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001206- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001207 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001208
Walter Dörwald36733692004-12-22 12:50:50 +00001209- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1210 once when a size argument is given. This prevents a buffer overflow in the
1211 tokenizer with very long source lines.
1212
Barry Warsaw538561e2006-01-01 21:48:54 +00001213- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1214 immediately after creating the object, without any intervening
1215 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001216
Skip Montanaro05885812005-01-16 20:48:27 +00001217- The reconvert.quote function can now emit triple-quoted strings. The
1218 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001219
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001220- ``UserString.MutableString`` now supports negative indices in
1221 ``__setitem__`` and ``__delitem__``
1222
Greg Ward40407942005-03-05 02:53:17 +00001223- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1224 correctly.
1225
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001226- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1227 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1228 character even if the user has passed a size parameter to get a proper
1229 line ending. Remove the special handling of a "\r\n" that has been split
1230 between two lines.
1231
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001232- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1233 about illegal code points. The codec now supports PEP 293 style error
1234 handlers.
1235
Walter Dörwald78a78b02005-09-01 12:04:29 +00001236- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001237 from the input stream, so that the output is a byte string in the correct
1238 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001239
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001240- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1241 considering it exactly like a '*'.
1242
Walter Dörwald007f8df2005-10-09 19:42:27 +00001243- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1244 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001245
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001246- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1247
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001248- Patch #1413711: Certain patterns of differences were making difflib
1249 touch the recursion limit.
1250
Walter Dörwald58917a62006-03-31 15:26:22 +00001251- Bug #947906: An object oriented interface has been added to the calendar
1252 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001253 called as a script (e.g. via ``python -mcalendar``). Localized month and
1254 weekday names can be ouput (even if an exotic encoding is used) using
1255 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001256
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001257Build
1258-----
1259
Neal Norwitz602d3392006-03-31 08:21:40 +00001260- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1261 by using -mieee gcc option.
1262
Martin v. Löwis86d66262006-02-17 08:40:11 +00001263- Patch #1432345: Make python compile on DragonFly.
1264
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001265- Build support for Win64-AMD64 was added.
1266
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001267- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1268
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001269- Patch #881820: look for openpty and forkpty also in libbsd.
1270
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001271- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1272 The zlib module is now builtin on Windows.
1273
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001274- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1275
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001276- Bug #1189330: configure did not correctly determine the necessary
1277 value of LINKCC if python was built with GCC 4.0.
1278
Trent Mick8321b422005-07-26 02:29:21 +00001279- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1280 vulnerability in zlib 1.2.1 and 1.2.2.
1281
Brett Cannon08cd5982005-04-24 22:26:38 +00001282- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1283 flags that change binary compatibility. Changes were also made to
1284 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001285 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001286
Bob Ippolitoed233462005-03-29 13:47:59 +00001287- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1288 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1289 no longer exists). This configure patch makes things right.
1290
Martin v. Löwise2713be2005-03-08 15:03:08 +00001291- Bug #1158607: Build with --disable-unicode again.
1292
Brett Cannon46d96232005-02-16 00:07:19 +00001293- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1294 defined. Discovered as a result of not being able to build on OS X.
1295
Brett Cannon516592f2004-12-07 00:42:59 +00001296- setup.py now uses the directories specified in LDFLAGS using the -L option
1297 and in CPPFLAGS using the -I option for adding library and include
1298 directories, respectively, for compiling extension modules against. This has
1299 led to the core being compiled using the values in CPPFLAGS. It also removes
1300 the need for the special-casing of both DarwinPorts and Fink for darwin since
1301 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1302 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1303 Fink, ``-I/opt/local/include`` for DarwinPorts).
1304
Brett Cannon43802422005-02-10 20:48:03 +00001305- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1306 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1307 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1308 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001310C API
1311-----
1312
Tim Petersc9d78aa2006-03-26 23:27:58 +00001313- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1314 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1315 is obtained via the ``PyObject_`` family, it must be released via the
1316 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1317 always been officially true, but when Python's small-object allocator was
1318 introduced, an attempt was made to cater to a few extension modules
1319 discovered at the time that obtained memory via ``PyObject_New`` but
1320 released it via ``PyMem_DEL``. It's years later, and if such code still
1321 exists it will fail now (probably with segfaults, but calling wrong
1322 low-level memory management functions can yield many symptoms).
1323
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001324- Added a C API for set and frozenset objects.
1325
Raymond Hettinger66517482004-12-03 11:45:13 +00001326- Removed PyRange_New().
1327
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001328- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1329 mapping argument now. This string is used as a mapping table. Byte values
1330 greater than the length of the string and 0xFFFE are treated as undefined
1331 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001338
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001339- Patch #1276356: New resource "urlfetch" is implemented. This enables
