Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================

Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlddbaa662006-06-04 21:56:52 +000015- Patch #1346214: Statements like "if 0: suite" are now again optimized
16 away like they were in Python 2.4.
17
Georg Brandlb7c8f542006-05-27 12:30:25 +000018- Builtin exceptions are now full-blown new-style classes instead of
19 instances pretending to be classes, which speeds up exception handling
20 by about 80% in comparison to 2.5a2.
21
Martin v. Löwisd004fc82006-05-27 08:36:52 +000022- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
23 Unicode 4.1.
24
Georg Brandlf4ef1162006-05-26 18:03:31 +000025- Patch #921466: sys.path_importer_cache is now used to cache valid and
26 invalid file paths for the built-in import machinery which leads to
27 fewer open calls on startup.
28
Tim Peters696cf432006-05-24 21:10:40 +000029- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
30 of-2 bases. The largest speedup is for inputs with about 1000 decimal
31 digits. Conversion from non-power-of-2 bases remains quadratic-time in
32 the number of input digits (it was and remains linear-time for bases
33 2, 4, 8, 16 and 32).
34
Tim Petersb713ec22006-05-23 18:45:30 +000035- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
36 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
37 an integer close to ``sys.maxint``. This was repaired by patch
38 #1335972, which also gives a nice speedup.
39
Richard Jonescebbefc2006-05-23 18:28:17 +000040- Patch #1337051: reduced size of frame objects.
41
42- PyErr_NewException now accepts a tuple of base classes as its
43 "base" parameter.
44
Richard Jones7c88dcc2006-05-23 10:37:38 +000045- Patch #876206: function call speedup by retaining allocated frame
46 objects.
47
Georg Brandl7b90e162006-05-18 07:01:27 +000048- Bug #1462152: file() now checks more thoroughly for invalid mode
49 strings and removes a possible "U" before passing the mode to the
50 C library function.
51
Neal Norwitz1004a532006-05-15 07:17:23 +000052- Patch #1488312, Fix memory alignment problem on SPARC in unicode
53
Neal Norwitz373f0a72006-05-15 07:04:36 +000054- Bug #1487966: Fix SystemError with conditional expression in assignment
55
Martin v. Löwis879768d2006-05-11 13:28:43 +000056- WindowsError now has two error code attributes: errno, which carries
57 the error values from errno.h, and winerror, which carries the error
58 values from winerror.h. Previous versions put the winerror.h values
59 (from GetLastError()) into the errno attribute.
60
Martin v. Löwis77736712006-05-04 05:51:03 +000061- Patch #1475845: Raise IndentationError for unexpected indent.
62
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000063- Patch #1479181: split open() and file() from being aliases for each other.
64
Tim Peters44bd9862006-06-01 13:49:23 +000065- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
66 methods were always silently ignored by dictionaries when comparing keys.
67 They are now passed through (except when using the C API function
68 ``PyDict_GetItem()``, whose semantics did not change).
69
70- Bug #1456209: In some obscure cases it was possible for a class with a
71 custom ``__eq__()`` method to confuse dict internals when class instances
72 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
73 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000075Extension Modules
76-----------------
77
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +000078- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
79
Nick Coghlanc649ec52006-05-29 12:43:05 +000080- Patch #1478788 (modified version): The functional extension module has
81 been renamed to _functools and a functools Python wrapper module added.
82 This provides a home for additional function related utilities that are
83 not specifically about functional programming. See PEP 309.
84
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000085- Patch #1493701: performance enhancements for struct module.
86
Georg Brandl378d5922006-05-17 14:26:50 +000087- Patch #1490224: time.altzone is now set correctly on Cygwin.
88
Georg Brandl8d3342b2006-05-16 07:38:27 +000089- Patch #1435422: zlib's compress and decompress objects now have a
90 copy() method.
91
Neal Norwitz7a5fc282006-05-15 06:48:14 +000092- On Win32, os.listdir now supports arbitrarily-long Unicode path names
93 (up to the system limit of 32K characters).
94
95- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
96 As a result, these functions now raise WindowsError instead of OSError.
97
Tim Peters7a822da2006-05-25 21:50:17 +000098- ``time.clock()`` on Win64 should use the high-performance Windows
99 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
100 Windows platforms).
101
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000102- Calling Tk_Init twice is refused if the first call failed as that
103 may deadlock.
104
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000105- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
106 accept it without potentially using an uninitialized pointer.
107
108- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
109 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
110 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000111
Gregory P. Smith372b5832006-06-05 18:48:21 +0000112- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000113 [pybsddb project SF patch number 1466734]
114
Gregory P. Smith372b5832006-06-05 18:48:21 +0000115- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
116 parameter is supplied. [SF pybsddb bug #1477863]
117
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000118- bsddb: the __len__ method of a DB object has been fixed to return correct
119 results. It could previously incorrectly return 0 in some cases.
120 Fixes SF bug 1493322 (pybsddb bug 1184012).
121
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000122- bsddb: the bsddb.dbtables Modify method now raises the proper error and
123 aborts the db transaction safely when a modifier callback fails.
124 Fixes SF python patch/bug #1408584.
125
Gregory P. Smith372b5832006-06-05 18:48:21 +0000126
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000127Library
128-------
129
Tim Petersd6a9eef2006-06-05 01:48:21 +0000130- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
131 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000132
Martin v. Löwis3f767792006-06-04 19:36:28 +0000133- Patch #1359618: Speed up charmap encoder by using a trie structure
134 for lookup.
135
Tim Petersd609b1a2006-06-02 23:22:51 +0000136- The functions in the ``pprint`` module now sort dictionaries by key
137 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
138 if and only if its display required more than one line, although that
139 wasn't documented. The new behavior increases predictability; e.g.,
140 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
141
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000142- Patch #1497027: try HTTP digest auth before basic auth in urllib2
143 (thanks for J. J. Lee).
144
Georg Brandl2b330372006-05-28 20:23:12 +0000145- Patch #1496206: improve urllib2 handling of passwords with respect to
146 default HTTP and HTTPS ports.
147
George Yoshidaf3c65de2006-05-28 16:39:09 +0000148- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
149
Bob Ippolito7298f272006-05-23 18:43:47 +0000150- Patch #1281707: speed up gzip.readline.
151
Georg Brandlb89316f2006-05-17 15:51:16 +0000152- Patch #1180296: Two new functions were added to the locale module:
153 format_string() to get the effect of "format % items" but locale-aware,
154 and currency() to format a monetary number with currency sign.
155
Georg Brandle3a25832006-05-17 14:56:04 +0000156- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
157 and several features added, such as speed and geometry control.
158
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000159- Patch #1488881: add support for external file objects in bz2 compressed
160 tarfiles.
161
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000162- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
163 stdout arguments, making it possible to redirect input and output
164 for remote debugging.
165
166- Patch #1484695: Update the tarfile module to version 0.8. This fixes
167 a couple of issues, notably handling of long file names using the
168 GNU LONGNAME extension.
169
170- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
171 new flag when ``name`` is already the name of an option flag.
172
173- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
174 package.
175
176- Patch #1472854: make the rlcompleter.Completer class usable on non-
177 UNIX platforms.
178
179- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000206What's New in Python 2.5 alpha 2?
207=================================
208
209*Release date: 27-APR-2006*
210
211Core and builtins
212-----------------
213
Thomas Heller1b046642006-04-18 18:51:06 +0000214- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
215 by converting these apis from macros into exported functions again:
216
217 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
218 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
219 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
220 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
221 PyRun_String Py_CompileString
222
Martin v. Löwis45294a92006-04-18 06:24:08 +0000223- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
224
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000225- All uses of PyStructSequence_InitType have been changed to initialize
226 the type objects only once, even if the interpreter is initialized
227 multiple times.
228
Neal Norwitz61546162006-04-14 05:20:28 +0000229- Bug #1454485, array.array('u') could crash the interpreter. This was
230 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
231 to unicode when it didn't make sense. 'u#' now requires a unicode string.
232
233- Py_UNICODE is unsigned. It was always documented as unsigned, but
234 due to a bug had a signed value in previous versions.
235
Tim Peters3a5e8b12006-04-11 01:44:07 +0000236- Patch #837242: ``id()`` of any Python object always gives a positive
237 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
238 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000239 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000240 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000241
Tim Peters3a5e8b12006-04-11 01:44:07 +0000242 def __hash__(self):
243 return id(self) # WRONG
244
245 because a hash result must be a (short) Python int but it was always
246 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000247 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000248 was always usable as a hash value before this patch. That's no longer
249 necessarily so.
250
251- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000252 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000253 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000254 #1454844)
255
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000256- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
257 involving generators that have paused outside of any ``try`` or ``with``
258 blocks. (In 2.5a1, a paused generator that was part of a reference
259 cycle could not be garbage collected, regardless of whether it was
260 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000262Extension Modules
263-----------------
264
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000265- Patch #1191065: Fix preprocessor problems on systems where recvfrom
266 is a macro.
267
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000268- Bug #1467952: os.listdir() now correctly raises an error if readdir()
269 fails with an error condition.
270
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000271- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
272
273- Bug #1117761: bsddb.*open() no longer raises an exception when using
274 the cachesize parameter.
275
276- Bug #1149413: bsddb.*open() no longer raises an exception when using
277 a temporary db (file=None) with the 'n' flag to truncate on open.
278
279- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
280 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000281
Armin Rigoa9017c32006-04-19 11:50:27 +0000282- Patch #1062014: AF_UNIX sockets under Linux have a special
283 abstract namespace that is now fully supported.
284
Anthony Baxter51bcb682006-04-05 14:51:42 +0000285Library
286-------
287
Tim Peters711bf302006-04-25 03:31:36 +0000288- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
289 a doctest to be skipped (the code is not run, and the expected output
290 or exception is ignored).
291
Nick Coghlanda2268f2006-04-24 04:37:15 +0000292- Fixed contextlib.nested to cope with exceptions being raised and
293 caught inside exit handlers.
294
Greg Wardab05edc2006-04-23 03:47:58 +0000295- Updated optparse module to Optik 1.5.1 (allow numeric constants in
296 hex, octal, or binary; add ``append_const`` action; keep going if
297 gettext cannot be imported; added ``OptionParser.destroy()`` method;
298 added ``epilog`` for better help generation).
299
Tim Peters21fbd572006-04-21 21:18:10 +0000300- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
301 called from a thread spawned as a side effect of importing a module.
302
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000303- The pydoc module now supports documenting packages contained in
304 .zip or .egg files.
305
306- The pkgutil module now has several new utility functions, such
307 as ``walk_packages()`` to support working with packages that are either
308 in the filesystem or zip files.
309
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000310- The mailbox module can now modify and delete messages from
311 mailboxes, in addition to simply reading them. Thanks to Gregory
312 K. Johnson for writing the code, and to the 2005 Google Summer of
313 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000314
Tim Petersc7605f22006-04-17 21:12:33 +0000315- The ``__del__`` method of class ``local`` in module ``_threading_local``
316 returned before accomplishing any of its intended cleanup.
317
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000318- Patch #790710: Add breakpoint command lists in pdb.
319
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000320- Patch #1063914: Add Tkinter.Misc.clipboard_get().
321
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000322- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
323
Anthony Baxtere29002c2006-04-12 12:07:31 +0000324- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
325 Windows. Bug #1469163.
326
Phillip J. Eby47032112006-04-11 01:07:43 +0000327- The warnings, linecache, inspect, traceback, site, and doctest modules
328 were updated to work correctly with modules imported from zipfiles or

343
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000344- The Makefile now has a reindent target, which runs reindent.py on
345 the library.
346

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000350
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000351- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
352 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000353 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000354 CXX from --with-cxx-main, see description in README.
355
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000356- Patch #1429775: Link extension modules with the shared libpython.
357
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000358- Fixed a libffi build problem on MIPS systems.
359
Tim Peters8931ff12006-05-13 23:28:20 +0000360- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
361 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
362 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000364Tests
365-----
366
Nick Coghlanda2268f2006-04-24 04:37:15 +0000367- test_contextlib now checks contextlib.nested can cope with exceptions
368 being raised and caught inside exit handlers.
369
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000370- test_cmd_line now checks operation of the -m and -c command switches
371
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000372- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
373 it separately and by hand. It also wasn't cleaning up its changes to
374 the current Decimal context.
375
Thomas Woutersabd08882006-04-26 15:53:30 +0000376- regrtest.py now has a -M option to run tests that test the new limits of
377 containers, on 64-bit architectures. Running these tests is only sensible
378 on 64-bit machines with more than two gigabytes of memory. The argument
379 passed is the maximum amount of memory for the tests to use.

388-------------
389
Tim Petersb06d28c2006-05-12 01:57:59 +0000390- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
391
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000392- PEP 343: Added Context Types section to the library reference
393 and attempted to bring other PEP 343 related documentation into
394 line with the implementation and/or python-dev discussions.
395
Tim Peters8dc73d22006-04-24 02:03:16 +0000396- Bug #1337990: clarified that ``doctest`` does not support examples
397 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000400What's New in Python 2.5 alpha 1?
401=================================
402
Anthony Baxterebed3f62006-04-03 15:03:44 +0000403*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000404
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000405Core and builtins
406-----------------
407
Nick Coghlan43832302006-04-23 17:04:07 +0000408- PEP 338: -m command line switch now delegates to runpy.run_module
409 allowing it to support modules in packages and zipfiles
410
Martin v. Löwisc661b882006-04-20 04:54:23 +0000411- On Windows, .DLL is not an accepted file name extension for
412 extension modules anymore; extensions are only found if they
413 end in .PYD.
414
Martin v. Löwisea62d252006-04-03 10:56:49 +0000415- Bug #1421664: sys.stderr.encoding is now set to the same value as
416 sys.stdout.encoding.
417
Neal Norwitz92e212f2006-04-03 04:48:37 +0000418- __import__ accepts keyword arguments.
419
Georg Brandlccadf842006-03-31 18:54:53 +0000420- Patch #1460496: round() now accepts keyword arguments.
421
Anthony Baxter262c00a2006-03-30 10:53:17 +0000422- Fixed bug #1459029 - unicode reprs were double-escaped.
423
Hye-Shik Changd478f342006-03-23 12:32:36 +0000424- Patch #1396919: The system scope threads are reenabled on FreeBSD
425 5.4 and later versions.
426
Neal Norwitze98ccf62006-03-23 05:39:47 +0000427- Bug #1115379: Compiling a Unicode string with an encoding declaration
428 now gives a SyntaxError.
429
Georg Brandlabd1ff82006-03-18 07:59:59 +0000430- Previously, Python code had no easy way to access the contents of a
431 cell object. Now, a ``cell_contents`` attribute has been added
432 (closes patch #1170323).
433
Tim Peterscf79aac2006-03-16 01:14:46 +0000434- Patch #1123430: Python's small-object allocator now returns an arena to
435 the system ``free()`` when all memory within an arena becomes unused
436 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
437 freed. Some applications will see a drop in virtual memory size now,
438 especially long-running applications that, from time to time, temporarily
439 use a large number of small objects. Note that when Python returns an
440 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000441 platform C library will in turn return that memory to the operating system.
442 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000443 appears to be effective at least on Microsoft C and gcc-based systems.
444 Thanks to Evan Jones for hard work and patience.
445
Georg Brandl533ff6f2006-03-08 18:09:27 +0000446- Patch #1434038: property() now uses the getter's docstring if there is
447 no "doc" argument given. This makes it possible to legitimately use
448 property() as a decorator to produce a read-only property.
449
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000450- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
451 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
452 of requiring an int or long in slicing and a few other contexts, enabling
453 other objects (e.g. Numeric Python's integers) to be used as slice indices.
454
Neal Norwitz995acdf2006-03-07 05:01:00 +0000455- Fixed various bugs reported by Coverity's Prevent tool.
456
Brett Cannonbf364092006-03-01 04:25:17 +0000457- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
458 new exception base class, BaseException, which has a new message attribute.
459 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
460 Raising a string exception now raises a DeprecationWarning.
461
Thomas Woutersfb609f42006-02-28 16:37:25 +0000462- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
463 explicitly relative, using 'from .module import name' to mean 'from the same
464 package as this module is in. Imports without dots still default to the
465 old relative-then-absolute, unless 'from __future__ import
466 absolute_import' is used.
467
Brett Cannona7446e32006-02-27 23:39:10 +0000468- Properly check if 'warnings' raises an exception (usually when a filter set
469 to "error" is triggered) when raising a warning for raising string
470 exceptions.
471
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000472- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000473 The name was removed from Include/code.h.
474
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000475- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000476
Guido van Rossum1968ad32006-02-25 22:38:04 +0000477- Patch 1433928:
478 - The copy module now "copies" function objects (as atomic objects).
479 - dict.__getitem__ now looks for a __missing__ hook before raising
480 KeyError.
481
Tim Peters84ef21c2006-02-28 20:39:06 +0000482- PEP 343: with statement implemented. Needs ``from __future__ import
483 with_statement``. Use of 'with' as a variable will generate a warning.
484 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000485 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000486 The following objects have __context__ methods:
487 - The built-in file type.
488 - The thread.LockType type.
489 - The following types defined by the threading module:
490 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
491 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000492
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000493- Fix the encodings package codec search function to only search
494 inside its own package. Fixes problem reported in patch #1433198.
495
496 Note: Codec packages should implement and register their own
497 codec search function. PEP 100 has the details.
498
Tim Peters9ea89d22006-06-04 03:26:02 +0000499- PEP 353: Using ``Py_ssize_t`` as the index type.
500
501- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
502 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
503 now allow Python to make use of memory blocks exceeding 2**32 bytes for
504 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
505 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000506
Neal Norwitzfc76d632006-01-10 06:03:13 +0000507- Patch #1400181, fix unicode string formatting to not use the locale.
508 This is how string objects work. u'%f' could use , instead of .
509 for the decimal point. Now both strings and unicode always use periods.
510
Neal Norwitz671b9e32006-01-09 07:07:12 +0000511- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
512 configure would break checking curses.h.
513
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000514- Bug #959576: The pwd module is now builtin. This allows Python to be
515 built on UNIX platforms without $HOME set.
516
Neal Norwitzc10978f2005-12-19 06:07:16 +0000517- Bug #1072182, fix some potential problems if characters are signed.
518
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000519- Bug #889500, fix line number on SyntaxWarning for global declarations.
520
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000521- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
522
Neal Norwitze7214a12005-12-18 05:03:17 +0000523- Support for converting hex strings to floats no longer works.
524 This was not portable. float('0x3') now raises a ValueError.
525
Barry Warsaw2a38a862005-12-18 01:27:35 +0000526- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000527 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000528 is now displayed in interactive prompt banner.
529
Georg Brandlfa166682005-12-17 21:45:17 +0000530- Implementation of PEP 341 - Unification of try/except and try/finally.
531 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000532 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000533
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000534- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
535 now encodes backslash correctly.
536
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000537- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
538
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000539- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000540 and long longs.
541
Neal Norwitz67715f02005-11-09 06:59:35 +0000542- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000543 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000544 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000545
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000546- Replaced most Unicode charmap codecs with new ones using the
547 new Unicode translate string feature in the builtin charmap
548 codec; the codecs were created from the mapping tables available
549 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
550 encodings now include a mapping for the Apple logo)
551
Tim Peterse3547fd2005-12-16 23:13:57 +0000552- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000553
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000554- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000555
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000556- A new AST parser implementation was completed. The abstract
557 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000558 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000559
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000560- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000561 The following code now raises a SyntaxError: foo(a = i for i in range(10))
562
Neal Norwitz708e51a2005-10-03 04:48:15 +0000563- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
564
Neal Norwitz11bd1192005-10-03 00:54:56 +0000565- SF Bug #887946: fix segfault when redirecting stdin from a directory.
566 Provide a warning when a directory is passed on the command line.
567
Neal Norwitz40d37812005-10-02 01:48:49 +0000568- Fix segfault with invalid coding.
569
570- SF bug #772896: unknown encoding results in MemoryError.
571
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000572- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000573 supported a __len__() method which evaluated to False when the iterator
574 was empty.
575
Guido van Rossum630db602005-09-20 18:49:54 +0000576- On 64-bit platforms, when __len__() returns a value that cannot be
577 represented as a C int, raise OverflowError.
578
Skip Montanarof8948ca2005-09-19 03:54:46 +0000579- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000580 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000581
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000582- SF bug #893549: parsing keyword arguments was broken with a few format
583 codes.
584
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000585- Changes donated by Elemental Security to make it work on AIX 5.3
586 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
587 bug #105470: test_pwd fails on 64bit system (Opteron).
588
Guido van Rossum539c6622005-09-14 17:49:54 +0000589- Changes donated by Elemental Security to make it work on HP-UX 11 on
590 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
591
Georg Brandl4550b8d2005-08-26 06:43:52 +0000592- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000593 (fixes bug #1119418).
594
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000595- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
596
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000597- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
598 exceptions that cause a function to exit.
599
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000600- The implementation of set() and frozenset() was revised to use its
601 own internal data structure. Memory consumption is reduced by 1/3
602 and there are modest speed-ups as well. The API is unchanged.
603
Tim Petersde7990b2005-07-17 23:45:23 +0000604- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
605
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000606- SF bug #1229429: PyObject_CallMethod failed to decrement some
607 reference counts in some error exit cases.

Tim Petersecc6e6a2005-07-10 22:30:55 +0000609- SF bug #1185883: Python's small-object memory allocator took over
610 a block managed by the platform C library whenever a realloc specified
611 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000612 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000613 portable way to copy data from the C-managed block into Python's
614 small-object space without risking a memory fault. Python's small-object
615 realloc now leaves such blocks under the control of the platform C
616 realloc.
617
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000618- SF bug #1232517: An overflow error was not detected properly when
619 attempting to convert a large float to an int in os.utime().
620
Raymond Hettinger3296e692005-06-29 23:29:56 +0000621- SF bug #1224347: hex longs now print with lowercase letters just
622 like their int counterparts.
623
Michael W. Hudson188d4362005-06-20 16:52:57 +0000624- SF bug #1163563: the original fix for bug #1010677 ("thread Module
625 Breaks PyGILState_Ensure()") broke badly in the case of multiple
626 interpreter states; back out that fix and do a better job (see
627 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
628 for a longer write-up of the problem).
629
Michael W. Hudsondf888462005-06-03 14:41:55 +0000630- SF patch #1180995: marshal now uses a binary format by default when
631 serializing floats.
632
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000633- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
634 the routines that promise to produce IEEE 754 binary representations
635 of floats now simply copy bytes around.
636
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000637- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
638 278.
639
Brett Cannonc3647ac2005-04-26 03:45:26 +0000640- patch #1109424: int, long, float, complex, and unicode now check for the
641 proper magic slot for type conversions when subclassed. Previously the
642 magic slot was ignored during conversion. Semantics now match the way
643 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000644 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000645 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000646 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000647
Barry Warsawc8d907c2005-04-19 23:43:40 +0000648- Descriptors defined in C with a PyGetSetDef structure, where the setter is
649 NULL, now raise an AttributeError when attempting to set or delete the
650 attribute. Previously a TypeError was raised, but this was inconsistent
651 with the equivalent pure-Python implementation.
652
Michael W. Hudson774479c2005-04-18 08:46:17 +0000653- It is now safe to call PyGILState_Release() before
654 PyEval_InitThreads() (note that if there is reason to believe there
655 are multiple threads around you still must call PyEval_InitThreads()
656 before using the Python API; this fix is for extension modules that
657 have no way of knowing if Python is multi-threaded yet).
658
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000659- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
660 disabled caused a crash.
661
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000662- Bug #1165306: instancemethod_new allowed the creation of a method
663 with im_class == im_self == NULL, which caused a crash when called.
664
Tim Petersecc6e6a2005-07-10 22:30:55 +0000665- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000666 fixes the crash seen in bug #1165761
667
Raymond Hettinger96229b12005-03-11 06:49:40 +0000668- Added two new builtins, any() and all().
669
Brett Cannon409d8f22005-03-05 06:47:57 +0000670- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000671 (e.g., ``class C(): pass`` is no longer a syntax error).
672 Patch #1176012 added support to the 'parser' module and 'compiler' package
673 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000674
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000675- Patch #1115086: Support PY_LONGLONG in structmember.
676
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000677- Bug #1155938: new style classes did not check that __init__() was
678 returning None.
679
Tim Petersecc6e6a2005-07-10 22:30:55 +0000680- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000681 ('\') with a specific error message.
682
Martin v. Löwisff232d72005-03-03 09:24:38 +0000683- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
684
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000685- Bug #1124295: the __name__ attribute of file objects was
686 inadvertently made inaccessible in restricted mode.
687
Tim Petersecc6e6a2005-07-10 22:30:55 +0000688- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000689 an ferror() call.
690
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000691- min() and max() now support key= arguments with the same meaning as in
692 list.sort().
693
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000694- The peephole optimizer now performs simple constant folding in expressions:
695 (2+3) --> (5).
696
Raymond Hettingera422c342005-01-11 03:03:27 +0000697- set and frozenset objects can now be marshalled. SF #1098985.
698
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000699- Bug #1077106: Poor argument checking could cause memory corruption
700 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000701
Jeremy Hyltonab630502005-02-04 18:44:06 +0000702- The parser did not complain about future statements in illegal
703 positions. It once again reports a syntax error if a future
704 statement occurs after anything other than a doc string.
705
Neil Schemenauercf52c072005-08-12 17:34:58 +0000706- Change the %s format specifier for str objects so that it returns a
707 unicode instance if the argument is not an instance of basestring and
708 calling __str__ on the argument returns a unicode instance.
709
Tim Petersf4e69282006-02-27 17:15:31 +0000710- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
711 current thread state when the auto-GIL-state machinery knows about
712 it (since the thread state is being deleted, continuing to remember it
713 can't help, but can hurt if another thread happens to get created with
714 the same thread id).
715

740 SS2 (single-shift 2) escape sequences correctly.
741
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000742- The unicodedata module was updated to the 4.1 version of the Unicode
743 database. The 3.2 version is still available as unicodedata.db_3_2_0
744 for applications that require this specific version (such as IDNA).
745
Neal Norwitzb62c4332006-03-04 18:35:47 +0000746- The timing module is no longer built by default. It was deprecated
747 in PEP 4 in Python 2.0 or earlier.
748
Guido van Rossum1968ad32006-02-25 22:38:04 +0000749- Patch 1433928: Added a new type, defaultdict, to the collections module.

754
Georg Brandlf4f44152006-02-18 22:29:33 +0000755- Patch #1393157: os.startfile() now has an optional argument to specify
756 a "command verb" to invoke on the file.
757
Neal Norwitz082b2df2006-02-07 07:04:46 +0000758- Bug #876637, prevent stack corruption when socket descriptor

Raymond Hettingera6b45cc2004-12-07 07:05:57 +0000890- the cPickle module no longer accepts the deprecated None option in the
891 args tuple returned by __reduce__().
892
Raymond Hettingerb2594052004-12-05 09:25:51 +0000893- itertools.islice() now accepts None for the start and step arguments.
894 This allows islice() to work more readily with slices:
895 islice(s.start, s.stop, s.step)
896
Skip Montanaro0af3ade2005-01-13 04:12:31 +0000897- datetime.datetime() now has a strptime class method which can be used to

904-------
905
Nick Coghlan43832302006-04-23 17:04:07 +0000906- PEP 338: new module runpy defines a run_module function to support
907 executing modules which provide access to source code or a code object
908 via the PEP 302 import mechanisms.
909
Anthony Baxter93f5b932006-04-03 08:05:07 +0000910- The email module's parsedate_tz function now sets the daylight savings
911 flag to -1 (unknown) since it can't tell from the date whether it should
912 be set.
913
Fred Drakead5177c2006-04-01 22:14:43 +0000914- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
915 now sport attributes that provide access to the parts of the result.
916
Georg Brandl7f6b67c2006-04-01 08:35:18 +0000917- Patch #1462498: sgmllib now handles entity and character references
918 in attribute values.
919
Anthony Baxterc51ee692006-04-01 00:57:31 +0000920- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000921 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000922 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000923 module will not be built.
924
Tim Petersc17976e2006-04-01 00:26:53 +0000925- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
926 aren't officially supported here, and trying to use them will probably
927 raise an exception some day. But dicts have been allowed, and "mostly
928 worked", so support for them won't go away without warning.
929
Georg Brandl338ef7d2006-03-31 18:42:16 +0000930- Bug #1445068: getpass.getpass() can now be given an explicit stream
931 argument to specify where to write the prompt.
932
Georg Brandl22ec80b2006-03-31 18:25:44 +0000933- Patch #1462313, bug #1443328: the pickle modules now can handle classes

939 key to be used for signing the uploaded code.
940
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000941- Queue.Queue objects now support .task_done() and .join() methods
942 to make it easier to monitor when daemon threads have completed
943 processing all enqueued tasks. Patch #1455676.
944
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000945- popen2.Popen objects now preserve the command in a .cmd attribute.
946

948
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000949- email 4.0 package now integrated. This is largely the same as the email 3.0
950 package that was included in Python 2.3, except that PEP 8 module names are
951 now used (e.g. mail.message instead of email.Message). The MIME classes
952 have been moved to a subpackage (e.g. email.mime.text instead of
953 email.MIMEText). The old names are still supported for now. Several
954 deprecated Message methods have been removed and lots of bugs have been
955 fixed. More details can be found in the email package documentation.
956
Walter Dörwald40108c92006-03-27 08:15:44 +0000957- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
958 (a subclass of tuple) that provides incremental decoders and encoders
959 (a way to use stateful codecs without the stream API). Python functions
960 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
961 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
962 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000963
Walter Dörwald067db482006-03-15 22:17:27 +0000964- Patch #1359365: Calling next() on a closed StringIO.String object raises
965 a ValueError instead of a StopIteration now (like file and cString.String do).
966 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
967 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000968
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000969- A regrtest option -w was added to re-run failed tests in verbose mode.

975 grew an optional 'generation' argument.
976
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000977- A library msilib to generate Windows Installer files, and a distutils
978 command bdist_msi have been added.

1043 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1044 Ronald L. Rivest offered this advice for Python:
1045
1046 "The consensus of researchers in this area (at least as
1047 expressed at the NIST Hash Function Workshop 10/31/05),
1048 is that SHA-256 is a good choice for the time being, but
1049 that research should continue, and other alternatives may
1050 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001051
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001052- Added a subset of Fredrik Lundh's ElementTree package. Available

1151
Georg Brandl9166e1a2005-06-04 09:20:03 +00001152- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1153
Georg Brandl268e61c2005-06-03 14:28:50 +00001154- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1155 component of the path.
1156
Skip Montanaro174dd222005-05-14 20:54:16 +00001157- Patch #1120353: The xmlrpclib module provides better, more transparent,
1158 support for datetime.{datetime,date,time} objects. With use_datetime set
1159 to True, applications shouldn't have to fiddle with the DateTime wrapper
1160 class at all.
1161
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001162- distutils.commands.upload was added to support uploading distribution
1163 files to PyPI.
1164
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001165- distutils.commands.register now encodes the data as UTF-8 before posting
1166 them to PyPI.
1167
Raymond Hettinger267b8682005-03-27 10:47:39 +00001168- decimal operator and comparison methods now return NotImplemented
1169 instead of raising a TypeError when interacting with other types. This
1170 allows other classes to implement __radd__ style methods and have them
1171 work as expected.
1172
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001173- Bug #1163325: Decimal infinities failed to hash. Attempting to
1174 hash a NaN raised an InvalidOperation instead of a TypeError.
1175
Tim Petersecc6e6a2005-07-10 22:30:55 +00001176- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001177 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1178
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001179- Patch #1043890: Add extractall method to tarfile.
1180
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001181- Patch #1075887: Don't require MSVC in distutils if there is nothing
1182 to build.
1183
Martin v. Löwis637431b2005-03-03 23:12:42 +00001184- Patch #1103407: Properly deal with tarfile iterators when untarring
1185 symbolic links on Windows.
1186
Tim Petersecc6e6a2005-07-10 22:30:55 +00001187- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001188 profile.py if available.
1189
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001190- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1191
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001192- Patch #1117454: Remove code to special-case cookies without values
1193 in LWPCookieJar.
1194
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001195- Patch #1117339: Add cookielib special name tests.
1196
Martin v. Löwise869eb12005-03-03 09:46:07 +00001197- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1198
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001199- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1200
Martin v. Löwisdf241532005-03-03 08:17:42 +00001201- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1202
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001203- Patch #1104111: Alter setup.py --help and --help-commands.
1204
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001205- Patch #1121234: Properly cleanup _exit and tkerror commands.
1206
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001207- Patch #1049151: xdrlib now unpacks booleans as True or False.
1208
Raymond Hettingerbab41432005-02-05 01:31:19 +00001209- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1210
Guido van Rossumd0641422005-02-03 15:01:24 +00001211- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1212 disables recursive traversal through instance attributes, which can
1213 be exploited in various ways.
1214
Tim Peterse3547fd2005-12-16 23:13:57 +00001215- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001216 flags on the HTTP listening socket.
1217
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001218- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1219 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1220
Tim Peterse3547fd2005-12-16 23:13:57 +00001221- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001222 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1223
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001224- Bug #1110478: Revert os.environ.update to do putenv again.
1225
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001226- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1227
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001228- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1229
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001230- Enhancements to the csv module:
1231
1232 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001233 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001234 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001235 + Dialect parameter parsing has been re-implemented to improve error
1236 reporting.
1237 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1238 dictates.
1239 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001240 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001241 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001242 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1243 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001244 + reader now allows \r characters to be quoted (previously it only allowed
1245 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001246 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001247 + Dialect classes passed to the module are no longer instantiated by
1248 the module before being parsed (the former validation scheme required
1249 this, but the mechanism was unreliable).
1250 + The dialect registry now contains instances of the internal
1251 C-coded dialect type, rather than references to python objects.
1252 + the internal c-coded dialect type is now immutable.
1253 + register_dialect now accepts the same keyword dialect specifications
1254 as the reader and writer, allowing the user to register dialects
1255 without first creating a dialect class.
1256 + a configurable limit to the size of parsed fields has been added -
1257 previously, an unmatched quote character could result in the entire
1258 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001259 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001260 the parser field size limit (returning the former limit). The initial
1261 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001262 + A line_num attribute has been added to the reader object, which tracks
1263 the number of lines read from the source iterator. This is not
1264 the same as the number of records returned, as records can span
1265 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001266 + reader and writer objects were not being registered with the cyclic-GC.
1267 This has been fixed.
1268
Brett Cannone6539c42005-01-08 02:43:53 +00001269- _DummyThread objects in the threading module now delete self.__block that is
1270 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1271 lock primitives tend to be limited in number and thus should not be wasted on
1272 a _DummyThread object. Fixes bug #1089632.
1273
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001274- The imghdr module now detects Exif files.
1275
Raymond Hettinger6065d322004-12-20 23:51:53 +00001276- StringIO.truncate() now correctly adjusts the size attribute.
1277 (Bug #951915).
1278
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001279- locale.py now uses an updated locale alias table (built using
1280 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1281 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001282 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001283
Raymond Hettinger3557f422004-12-07 12:02:02 +00001284- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1285
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001286- the pickle module no longer accepts the deprecated None option in the
1287 args tuple returned by __reduce__().
1288
Brett Cannon84667c02004-12-07 03:25:18 +00001289- optparse now optionally imports gettext. This allows its use in setup.py.
1290
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001291- the pickle module no longer uses the deprecated bin parameter.
1292
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001293- the shelve module no longer uses the deprecated binary parameter.
1294
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001295- the pstats module no longer uses the deprecated ignore() method.
1296
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001297- the filecmp module no longer uses the deprecated use_statcache argument.
1298
Raymond Hettinger664347b2004-12-04 21:21:53 +00001299- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1300 extended or overridden by subclasses. Formerly, the subclassed method would
1301 be ignored by the rest of the module. (Bug #1078905).
1302
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001303- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001304 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001305
Walter Dörwald36733692004-12-22 12:50:50 +00001306- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1307 once when a size argument is given. This prevents a buffer overflow in the
1308 tokenizer with very long source lines.
1309
Barry Warsaw538561e2006-01-01 21:48:54 +00001310- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1311 immediately after creating the object, without any intervening
1312 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001313
Skip Montanaro05885812005-01-16 20:48:27 +00001314- The reconvert.quote function can now emit triple-quoted strings. The
1315 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001316
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001317- ``UserString.MutableString`` now supports negative indices in
1318 ``__setitem__`` and ``__delitem__``
1319
Greg Ward40407942005-03-05 02:53:17 +00001320- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1321 correctly.
1322
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001323- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1324 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1325 character even if the user has passed a size parameter to get a proper
1326 line ending. Remove the special handling of a "\r\n" that has been split
1327 between two lines.
1328
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001329- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1330 about illegal code points. The codec now supports PEP 293 style error
1331 handlers.
1332
Walter Dörwald78a78b02005-09-01 12:04:29 +00001333- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001334 from the input stream, so that the output is a byte string in the correct
1335 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001336
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001337- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1338 considering it exactly like a '*'.
1339
Walter Dörwald007f8df2005-10-09 19:42:27 +00001340- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1341 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001342
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001343- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1344
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001345- Patch #1413711: Certain patterns of differences were making difflib
1346 touch the recursion limit.
1347
Walter Dörwald58917a62006-03-31 15:26:22 +00001348- Bug #947906: An object oriented interface has been added to the calendar
1349 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001350 called as a script (e.g. via ``python -mcalendar``). Localized month and
1351 weekday names can be ouput (even if an exotic encoding is used) using
1352 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001353

1355-----
1356
Neal Norwitz602d3392006-03-31 08:21:40 +00001357- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1358 by using -mieee gcc option.
1359
Martin v. Löwis86d66262006-02-17 08:40:11 +00001360- Patch #1432345: Make python compile on DragonFly.
1361
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001362- Build support for Win64-AMD64 was added.
1363
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001364- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1365
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001366- Patch #881820: look for openpty and forkpty also in libbsd.
1367
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001368- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1369 The zlib module is now builtin on Windows.
1370
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001371- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1372
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001373- Bug #1189330: configure did not correctly determine the necessary
1374 value of LINKCC if python was built with GCC 4.0.
1375
Trent Mick8321b422005-07-26 02:29:21 +00001376- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1377 vulnerability in zlib 1.2.1 and 1.2.2.
1378
Brett Cannon08cd5982005-04-24 22:26:38 +00001379- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1380 flags that change binary compatibility. Changes were also made to
1381 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001382 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001383
Bob Ippolitoed233462005-03-29 13:47:59 +00001384- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1385 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1386 no longer exists). This configure patch makes things right.
1387
Martin v. Löwise2713be2005-03-08 15:03:08 +00001388- Bug #1158607: Build with --disable-unicode again.
1389
Brett Cannon46d96232005-02-16 00:07:19 +00001390- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1391 defined. Discovered as a result of not being able to build on OS X.
1392
Brett Cannon516592f2004-12-07 00:42:59 +00001393- setup.py now uses the directories specified in LDFLAGS using the -L option
1394 and in CPPFLAGS using the -I option for adding library and include
1395 directories, respectively, for compiling extension modules against. This has
1396 led to the core being compiled using the values in CPPFLAGS. It also removes
1397 the need for the special-casing of both DarwinPorts and Fink for darwin since
1398 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1399 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1400 Fink, ``-I/opt/local/include`` for DarwinPorts).
1401
Brett Cannon43802422005-02-10 20:48:03 +00001402- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1403 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1404 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1405 Closes bug #1096244. Thanks Gregory Bond.

1408-----
1409
Tim Petersc9d78aa2006-03-26 23:27:58 +00001410- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1411 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1412 is obtained via the ``PyObject_`` family, it must be released via the
1413 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1414 always been officially true, but when Python's small-object allocator was
1415 introduced, an attempt was made to cater to a few extension modules
1416 discovered at the time that obtained memory via ``PyObject_New`` but
1417 released it via ``PyMem_DEL``. It's years later, and if such code still
1418 exists it will fail now (probably with segfaults, but calling wrong
1419 low-level memory management functions can yield many symptoms).

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001425- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1426 mapping argument now. This string is used as a mapping table. Byte values
1427 greater than the length of the string and 0xFFFE are treated as undefined
1428 mappings.
