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.

Georg Brandl66a0dbb2006-06-08 12:54:13 +0000184- Bug #1502728: Correctly link against librt library on HP-UX.
185
Martin v. Löwis222c5152006-06-03 07:37:13 +0000186- OpenBSD 3.9 is supported now.
187
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000188- Patch #1492356: Port to Windows CE.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000208What's New in Python 2.5 alpha 2?
209=================================
210
211*Release date: 27-APR-2006*
212
213Core and builtins
214-----------------
215
Thomas Heller1b046642006-04-18 18:51:06 +0000216- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
217 by converting these apis from macros into exported functions again:
218
219 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
220 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
221 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
222 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
223 PyRun_String Py_CompileString
224
Martin v. Löwis45294a92006-04-18 06:24:08 +0000225- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
226
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000227- All uses of PyStructSequence_InitType have been changed to initialize
228 the type objects only once, even if the interpreter is initialized
229 multiple times.
230
Neal Norwitz61546162006-04-14 05:20:28 +0000231- Bug #1454485, array.array('u') could crash the interpreter. This was
232 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
233 to unicode when it didn't make sense. 'u#' now requires a unicode string.
234
235- Py_UNICODE is unsigned. It was always documented as unsigned, but
236 due to a bug had a signed value in previous versions.
237
Tim Peters3a5e8b12006-04-11 01:44:07 +0000238- Patch #837242: ``id()`` of any Python object always gives a positive
239 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
240 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000241 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000242 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000243
Tim Peters3a5e8b12006-04-11 01:44:07 +0000244 def __hash__(self):
245 return id(self) # WRONG
246
247 because a hash result must be a (short) Python int but it was always
248 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000249 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000250 was always usable as a hash value before this patch. That's no longer
251 necessarily so.
252
253- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000254 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000255 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000256 #1454844)
257
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000258- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
259 involving generators that have paused outside of any ``try`` or ``with``
260 blocks. (In 2.5a1, a paused generator that was part of a reference
261 cycle could not be garbage collected, regardless of whether it was
262 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000264Extension Modules
265-----------------
266
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000267- Patch #1191065: Fix preprocessor problems on systems where recvfrom
268 is a macro.
269
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000270- Bug #1467952: os.listdir() now correctly raises an error if readdir()
271 fails with an error condition.
272
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000273- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
274
275- Bug #1117761: bsddb.*open() no longer raises an exception when using
276 the cachesize parameter.
277
278- Bug #1149413: bsddb.*open() no longer raises an exception when using
279 a temporary db (file=None) with the 'n' flag to truncate on open.
280
281- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
282 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000283
Armin Rigoa9017c32006-04-19 11:50:27 +0000284- Patch #1062014: AF_UNIX sockets under Linux have a special
285 abstract namespace that is now fully supported.
286
Anthony Baxter51bcb682006-04-05 14:51:42 +0000287Library
288-------
289
Tim Peters711bf302006-04-25 03:31:36 +0000290- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
291 a doctest to be skipped (the code is not run, and the expected output
292 or exception is ignored).
293
Nick Coghlanda2268f2006-04-24 04:37:15 +0000294- Fixed contextlib.nested to cope with exceptions being raised and
295 caught inside exit handlers.
296
Greg Wardab05edc2006-04-23 03:47:58 +0000297- Updated optparse module to Optik 1.5.1 (allow numeric constants in
298 hex, octal, or binary; add ``append_const`` action; keep going if
299 gettext cannot be imported; added ``OptionParser.destroy()`` method;
300 added ``epilog`` for better help generation).
301
Tim Peters21fbd572006-04-21 21:18:10 +0000302- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
303 called from a thread spawned as a side effect of importing a module.
304
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000305- The pydoc module now supports documenting packages contained in
306 .zip or .egg files.
307
308- The pkgutil module now has several new utility functions, such
309 as ``walk_packages()`` to support working with packages that are either
310 in the filesystem or zip files.
311
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000312- The mailbox module can now modify and delete messages from
313 mailboxes, in addition to simply reading them. Thanks to Gregory
314 K. Johnson for writing the code, and to the 2005 Google Summer of
315 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000316
Tim Petersc7605f22006-04-17 21:12:33 +0000317- The ``__del__`` method of class ``local`` in module ``_threading_local``
318 returned before accomplishing any of its intended cleanup.
319
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000320- Patch #790710: Add breakpoint command lists in pdb.
321
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000322- Patch #1063914: Add Tkinter.Misc.clipboard_get().
323
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000324- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
325
Anthony Baxtere29002c2006-04-12 12:07:31 +0000326- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on

339
Skip Montanaro262fb922006-04-21 02:31:07 +0000340- The pstats.Stats class accepts an optional stream keyword argument to
341 direct output to an alternate file-like object.
342
Anthony Baxter51bcb682006-04-05 14:51:42 +0000343Build
344-----
345
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000346- The Makefile now has a reindent target, which runs reindent.py on
347 the library.
348
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000349- Patch #1470875: Building Python with MS Free Compiler
350
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000351- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000352
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000353- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
354 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000355 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000356 CXX from --with-cxx-main, see description in README.
357
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000358- Patch #1429775: Link extension modules with the shared libpython.
359
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000360- Fixed a libffi build problem on MIPS systems.
361
Tim Peters8931ff12006-05-13 23:28:20 +0000362- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
363 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
364 and "%zu" for unsigned integers of type ``size_t``.
365
Anthony Baxter51bcb682006-04-05 14:51:42 +0000366Tests
367-----
368
Nick Coghlanda2268f2006-04-24 04:37:15 +0000369- test_contextlib now checks contextlib.nested can cope with exceptions
370 being raised and caught inside exit handlers.
371
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000372- test_cmd_line now checks operation of the -m and -c command switches
373
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000374- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
375 it separately and by hand. It also wasn't cleaning up its changes to
376 the current Decimal context.
377
Thomas Woutersabd08882006-04-26 15:53:30 +0000378- regrtest.py now has a -M option to run tests that test the new limits of
379 containers, on 64-bit architectures. Running these tests is only sensible
380 on 64-bit machines with more than two gigabytes of memory. The argument
381 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000389Documentation
390-------------
391
Tim Petersb06d28c2006-05-12 01:57:59 +0000392- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
393
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000394- PEP 343: Added Context Types section to the library reference
395 and attempted to bring other PEP 343 related documentation into
396 line with the implementation and/or python-dev discussions.
397
Tim Peters8dc73d22006-04-24 02:03:16 +0000398- Bug #1337990: clarified that ``doctest`` does not support examples
399 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000402What's New in Python 2.5 alpha 1?
403=================================
404
Anthony Baxterebed3f62006-04-03 15:03:44 +0000405*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000406
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000407Core and builtins
408-----------------
409
Nick Coghlan43832302006-04-23 17:04:07 +0000410- PEP 338: -m command line switch now delegates to runpy.run_module
411 allowing it to support modules in packages and zipfiles
412
Martin v. Löwisc661b882006-04-20 04:54:23 +0000413- On Windows, .DLL is not an accepted file name extension for
414 extension modules anymore; extensions are only found if they
415 end in .PYD.
416
Martin v. Löwisea62d252006-04-03 10:56:49 +0000417- Bug #1421664: sys.stderr.encoding is now set to the same value as
418 sys.stdout.encoding.
419
Neal Norwitz92e212f2006-04-03 04:48:37 +0000420- __import__ accepts keyword arguments.
421
Georg Brandlccadf842006-03-31 18:54:53 +0000422- Patch #1460496: round() now accepts keyword arguments.
423
Anthony Baxter262c00a2006-03-30 10:53:17 +0000424- Fixed bug #1459029 - unicode reprs were double-escaped.
425
Hye-Shik Changd478f342006-03-23 12:32:36 +0000426- Patch #1396919: The system scope threads are reenabled on FreeBSD
427 5.4 and later versions.
428
Neal Norwitze98ccf62006-03-23 05:39:47 +0000429- Bug #1115379: Compiling a Unicode string with an encoding declaration
430 now gives a SyntaxError.
431
Georg Brandlabd1ff82006-03-18 07:59:59 +0000432- Previously, Python code had no easy way to access the contents of a
433 cell object. Now, a ``cell_contents`` attribute has been added
434 (closes patch #1170323).
435
Tim Peterscf79aac2006-03-16 01:14:46 +0000436- Patch #1123430: Python's small-object allocator now returns an arena to
437 the system ``free()`` when all memory within an arena becomes unused
438 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
439 freed. Some applications will see a drop in virtual memory size now,
440 especially long-running applications that, from time to time, temporarily
441 use a large number of small objects. Note that when Python returns an
442 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000443 platform C library will in turn return that memory to the operating system.
444 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000445 appears to be effective at least on Microsoft C and gcc-based systems.
446 Thanks to Evan Jones for hard work and patience.
447
Georg Brandl533ff6f2006-03-08 18:09:27 +0000448- Patch #1434038: property() now uses the getter's docstring if there is
449 no "doc" argument given. This makes it possible to legitimately use
450 property() as a decorator to produce a read-only property.
451
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000452- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
453 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
454 of requiring an int or long in slicing and a few other contexts, enabling
455 other objects (e.g. Numeric Python's integers) to be used as slice indices.
456
Neal Norwitz995acdf2006-03-07 05:01:00 +0000457- Fixed various bugs reported by Coverity's Prevent tool.
458
Brett Cannonbf364092006-03-01 04:25:17 +0000459- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
460 new exception base class, BaseException, which has a new message attribute.
461 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
462 Raising a string exception now raises a DeprecationWarning.
463
Thomas Woutersfb609f42006-02-28 16:37:25 +0000464- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
465 explicitly relative, using 'from .module import name' to mean 'from the same
466 package as this module is in. Imports without dots still default to the
467 old relative-then-absolute, unless 'from __future__ import
468 absolute_import' is used.
469
Brett Cannona7446e32006-02-27 23:39:10 +0000470- Properly check if 'warnings' raises an exception (usually when a filter set
471 to "error" is triggered) when raising a warning for raising string
472 exceptions.
473
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000474- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000475 The name was removed from Include/code.h.
476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000477- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000478
Guido van Rossum1968ad32006-02-25 22:38:04 +0000479- Patch 1433928:
480 - The copy module now "copies" function objects (as atomic objects).
481 - dict.__getitem__ now looks for a __missing__ hook before raising
482 KeyError.
483
Tim Peters84ef21c2006-02-28 20:39:06 +0000484- PEP 343: with statement implemented. Needs ``from __future__ import
485 with_statement``. Use of 'with' as a variable will generate a warning.
486 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000487 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000488 The following objects have __context__ methods:
489 - The built-in file type.
490 - The thread.LockType type.
491 - The following types defined by the threading module:
492 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
493 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000494
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000495- Fix the encodings package codec search function to only search
496 inside its own package. Fixes problem reported in patch #1433198.
497
498 Note: Codec packages should implement and register their own
499 codec search function. PEP 100 has the details.
500
Tim Peters9ea89d22006-06-04 03:26:02 +0000501- PEP 353: Using ``Py_ssize_t`` as the index type.
502
503- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
504 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
505 now allow Python to make use of memory blocks exceeding 2**32 bytes for
506 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
507 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000508
Neal Norwitzfc76d632006-01-10 06:03:13 +0000509- Patch #1400181, fix unicode string formatting to not use the locale.
510 This is how string objects work. u'%f' could use , instead of .
511 for the decimal point. Now both strings and unicode always use periods.
512
Neal Norwitz671b9e32006-01-09 07:07:12 +0000513- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
514 configure would break checking curses.h.
515
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000516- Bug #959576: The pwd module is now builtin. This allows Python to be
517 built on UNIX platforms without $HOME set.
518
Neal Norwitzc10978f2005-12-19 06:07:16 +0000519- Bug #1072182, fix some potential problems if characters are signed.
520
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000521- Bug #889500, fix line number on SyntaxWarning for global declarations.
522
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000523- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
524
Neal Norwitze7214a12005-12-18 05:03:17 +0000525- Support for converting hex strings to floats no longer works.
526 This was not portable. float('0x3') now raises a ValueError.
527
Barry Warsaw2a38a862005-12-18 01:27:35 +0000528- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000529 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000530 is now displayed in interactive prompt banner.
531
Georg Brandlfa166682005-12-17 21:45:17 +0000532- Implementation of PEP 341 - Unification of try/except and try/finally.
533 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000534 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000535
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000536- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
537 now encodes backslash correctly.
538
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000539- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
540
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000541- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000542 and long longs.
543
Neal Norwitz67715f02005-11-09 06:59:35 +0000544- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000545 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000546 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000547
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000548- Replaced most Unicode charmap codecs with new ones using the
549 new Unicode translate string feature in the builtin charmap
550 codec; the codecs were created from the mapping tables available
551 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
552 encodings now include a mapping for the Apple logo)
553
Tim Peterse3547fd2005-12-16 23:13:57 +0000554- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000556- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000557
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000558- A new AST parser implementation was completed. The abstract
559 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000560 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000561
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000562- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000563 The following code now raises a SyntaxError: foo(a = i for i in range(10))
564
Neal Norwitz708e51a2005-10-03 04:48:15 +0000565- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
566
Neal Norwitz11bd1192005-10-03 00:54:56 +0000567- SF Bug #887946: fix segfault when redirecting stdin from a directory.
568 Provide a warning when a directory is passed on the command line.
569
Neal Norwitz40d37812005-10-02 01:48:49 +0000570- Fix segfault with invalid coding.
571
572- SF bug #772896: unknown encoding results in MemoryError.
573
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000574- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000575 supported a __len__() method which evaluated to False when the iterator
576 was empty.
577
Guido van Rossum630db602005-09-20 18:49:54 +0000578- On 64-bit platforms, when __len__() returns a value that cannot be
579 represented as a C int, raise OverflowError.
580
Skip Montanarof8948ca2005-09-19 03:54:46 +0000581- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000582 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000583
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000584- SF bug #893549: parsing keyword arguments was broken with a few format
585 codes.
586
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000587- Changes donated by Elemental Security to make it work on AIX 5.3
588 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
589 bug #105470: test_pwd fails on 64bit system (Opteron).
590
Guido van Rossum539c6622005-09-14 17:49:54 +0000591- Changes donated by Elemental Security to make it work on HP-UX 11 on
592 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
593
Georg Brandl4550b8d2005-08-26 06:43:52 +0000594- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000595 (fixes bug #1119418).
596
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000597- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
598
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000599- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
600 exceptions that cause a function to exit.
601
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000602- The implementation of set() and frozenset() was revised to use its
603 own internal data structure. Memory consumption is reduced by 1/3
604 and there are modest speed-ups as well. The API is unchanged.
605
Tim Petersde7990b2005-07-17 23:45:23 +0000606- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
607
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000608- SF bug #1229429: PyObject_CallMethod failed to decrement some
609 reference counts in some error exit cases.
610
Tim Petersecc6e6a2005-07-10 22:30:55 +0000611- SF bug #1185883: Python's small-object memory allocator took over
612 a block managed by the platform C library whenever a realloc specified
613 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000614 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000615 portable way to copy data from the C-managed block into Python's
616 small-object space without risking a memory fault. Python's small-object
617 realloc now leaves such blocks under the control of the platform C
618 realloc.
619
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000620- SF bug #1232517: An overflow error was not detected properly when
621 attempting to convert a large float to an int in os.utime().
622
Raymond Hettinger3296e692005-06-29 23:29:56 +0000623- SF bug #1224347: hex longs now print with lowercase letters just
624 like their int counterparts.
625
Michael W. Hudson188d4362005-06-20 16:52:57 +0000626- SF bug #1163563: the original fix for bug #1010677 ("thread Module
627 Breaks PyGILState_Ensure()") broke badly in the case of multiple
628 interpreter states; back out that fix and do a better job (see
629 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
630 for a longer write-up of the problem).
631
Michael W. Hudsondf888462005-06-03 14:41:55 +0000632- SF patch #1180995: marshal now uses a binary format by default when
633 serializing floats.
634
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000635- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
636 the routines that promise to produce IEEE 754 binary representations
637 of floats now simply copy bytes around.
638
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000639- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
640 278.
641
Brett Cannonc3647ac2005-04-26 03:45:26 +0000642- patch #1109424: int, long, float, complex, and unicode now check for the
643 proper magic slot for type conversions when subclassed. Previously the
644 magic slot was ignored during conversion. Semantics now match the way
645 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000646 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000647 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000648 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000649
Barry Warsawc8d907c2005-04-19 23:43:40 +0000650- Descriptors defined in C with a PyGetSetDef structure, where the setter is
651 NULL, now raise an AttributeError when attempting to set or delete the
652 attribute. Previously a TypeError was raised, but this was inconsistent
653 with the equivalent pure-Python implementation.
654
Michael W. Hudson774479c2005-04-18 08:46:17 +0000655- It is now safe to call PyGILState_Release() before
656 PyEval_InitThreads() (note that if there is reason to believe there
657 are multiple threads around you still must call PyEval_InitThreads()
658 before using the Python API; this fix is for extension modules that
659 have no way of knowing if Python is multi-threaded yet).
660
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000661- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
662 disabled caused a crash.
663
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000664- Bug #1165306: instancemethod_new allowed the creation of a method
665 with im_class == im_self == NULL, which caused a crash when called.
666
Tim Petersecc6e6a2005-07-10 22:30:55 +0000667- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000668 fixes the crash seen in bug #1165761
669
Raymond Hettinger96229b12005-03-11 06:49:40 +0000670- Added two new builtins, any() and all().
671
Brett Cannon409d8f22005-03-05 06:47:57 +0000672- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000673 (e.g., ``class C(): pass`` is no longer a syntax error).
674 Patch #1176012 added support to the 'parser' module and 'compiler' package
675 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000676
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000677- Patch #1115086: Support PY_LONGLONG in structmember.
678
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000679- Bug #1155938: new style classes did not check that __init__() was
680 returning None.
681
Tim Petersecc6e6a2005-07-10 22:30:55 +0000682- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000683 ('\') with a specific error message.
684
Martin v. Löwisff232d72005-03-03 09:24:38 +0000685- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
686
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000687- Bug #1124295: the __name__ attribute of file objects was
688 inadvertently made inaccessible in restricted mode.
689
Tim Petersecc6e6a2005-07-10 22:30:55 +0000690- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000691 an ferror() call.
692
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000693- min() and max() now support key= arguments with the same meaning as in
694 list.sort().
695
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000696- The peephole optimizer now performs simple constant folding in expressions:
697 (2+3) --> (5).
698
Raymond Hettingera422c342005-01-11 03:03:27 +0000699- set and frozenset objects can now be marshalled. SF #1098985.
700
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000701- Bug #1077106: Poor argument checking could cause memory corruption
702 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000703
Jeremy Hyltonab630502005-02-04 18:44:06 +0000704- The parser did not complain about future statements in illegal
705 positions. It once again reports a syntax error if a future
706 statement occurs after anything other than a doc string.
707
Neil Schemenauercf52c072005-08-12 17:34:58 +0000708- Change the %s format specifier for str objects so that it returns a
709 unicode instance if the argument is not an instance of basestring and
710 calling __str__ on the argument returns a unicode instance.
711
Tim Petersf4e69282006-02-27 17:15:31 +0000712- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
713 current thread state when the auto-GIL-state machinery knows about
714 it (since the thread state is being deleted, continuing to remember it
715 can't help, but can hurt if another thread happens to get created with
716 the same thread id).
717

735
736- The following modules were removed: regsub, reconvert, regex, regex_syntax.
737
738- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000739 is deprecated. The undocumented re.engine variable no longer exists.

742 SS2 (single-shift 2) escape sequences correctly.
743
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000744- The unicodedata module was updated to the 4.1 version of the Unicode
745 database. The 3.2 version is still available as unicodedata.db_3_2_0
746 for applications that require this specific version (such as IDNA).
747
Neal Norwitzb62c4332006-03-04 18:35:47 +0000748- The timing module is no longer built by default. It was deprecated
749 in PEP 4 in Python 2.0 or earlier.
750
Guido van Rossum1968ad32006-02-25 22:38:04 +0000751- Patch 1433928: Added a new type, defaultdict, to the collections module.

753
Georg Brandldbd83392006-02-20 09:42:33 +0000754- Bug #854823: socketmodule now builds on Sun platforms even when

756
Georg Brandlf4f44152006-02-18 22:29:33 +0000757- Patch #1393157: os.startfile() now has an optional argument to specify
758 a "command verb" to invoke on the file.
759
Neal Norwitz082b2df2006-02-07 07:04:46 +0000760- Bug #876637, prevent stack corruption when socket descriptor

768 than the system default domain.
769
Martin v. Löwis14694662006-02-03 12:54:16 +0000770- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
771 are reported, the limit on path name lengths is removed, and stat reports
772 WindowsError now (instead of OSError).
773

Raymond Hettingerb2594052004-12-05 09:25:51 +0000895- itertools.islice() now accepts None for the start and step arguments.
896 This allows islice() to work more readily with slices:
897 islice(s.start, s.stop, s.step)
898

906-------
907
Nick Coghlan43832302006-04-23 17:04:07 +0000908- PEP 338: new module runpy defines a run_module function to support
909 executing modules which provide access to source code or a code object
910 via the PEP 302 import mechanisms.
911
Anthony Baxter93f5b932006-04-03 08:05:07 +0000912- The email module's parsedate_tz function now sets the daylight savings

920 in attribute values.
921
Anthony Baxterc51ee692006-04-01 00:57:31 +0000922- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000923 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000924 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000925 module will not be built.
926
Tim Petersc17976e2006-04-01 00:26:53 +0000927- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
928 aren't officially supported here, and trying to use them will probably
929 raise an exception some day. But dicts have been allowed, and "mostly
930 worked", so support for them won't go away without warning.
931
Georg Brandl338ef7d2006-03-31 18:42:16 +0000932- Bug #1445068: getpass.getpass() can now be given an explicit stream
933 argument to specify where to write the prompt.
934
Georg Brandl22ec80b2006-03-31 18:25:44 +0000935- Patch #1462313, bug #1443328: the pickle modules now can handle classes

942
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000943- Queue.Queue objects now support .task_done() and .join() methods
944 to make it easier to monitor when daemon threads have completed

950
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000951- email 4.0 package now integrated. This is largely the same as the email 3.0
952 package that was included in Python 2.3, except that PEP 8 module names are
953 now used (e.g. mail.message instead of email.Message). The MIME classes
954 have been moved to a subpackage (e.g. email.mime.text instead of
955 email.MIMEText). The old names are still supported for now. Several
956 deprecated Message methods have been removed and lots of bugs have been
957 fixed. More details can be found in the email package documentation.
958
Walter Dörwald40108c92006-03-27 08:15:44 +0000959- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
960 (a subclass of tuple) that provides incremental decoders and encoders
961 (a way to use stateful codecs without the stream API). Python functions
962 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
963 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
964 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000965
Walter Dörwald067db482006-03-15 22:17:27 +0000966- Patch #1359365: Calling next() on a closed StringIO.String object raises
967 a ValueError instead of a StopIteration now (like file and cString.String do).
968 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
969 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000970
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000971- A regrtest option -w was added to re-run failed tests in verbose mode.

977 grew an optional 'generation' argument.
978
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000979- A library msilib to generate Windows Installer files, and a distutils
980 command bdist_msi have been added.
981

997 current file number.
998

1044 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1045 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1046 Ronald L. Rivest offered this advice for Python:
1047
1048 "The consensus of researchers in this area (at least as
1049 expressed at the NIST Hash Function Workshop 10/31/05),
1050 is that SHA-256 is a good choice for the time being, but
1051 that research should continue, and other alternatives may
1052 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001053
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001054- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +00001149- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001150 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001151 the generate_tokens() function now accepts a callable argument that
1152 terminates by raising StopIteration.
1153
Georg Brandl9166e1a2005-06-04 09:20:03 +00001154- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1155
Georg Brandl268e61c2005-06-03 14:28:50 +00001156- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1157 component of the path.
1158
Skip Montanaro174dd222005-05-14 20:54:16 +00001159- Patch #1120353: The xmlrpclib module provides better, more transparent,
1160 support for datetime.{datetime,date,time} objects. With use_datetime set
1161 to True, applications shouldn't have to fiddle with the DateTime wrapper
1162 class at all.
1163
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001164- distutils.commands.upload was added to support uploading distribution
1165 files to PyPI.
1166
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001167- distutils.commands.register now encodes the data as UTF-8 before posting
1168 them to PyPI.
1169
Raymond Hettinger267b8682005-03-27 10:47:39 +00001170- decimal operator and comparison methods now return NotImplemented
1171 instead of raising a TypeError when interacting with other types. This
1172 allows other classes to implement __radd__ style methods and have them
1173 work as expected.
1174
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001175- Bug #1163325: Decimal infinities failed to hash. Attempting to
1176 hash a NaN raised an InvalidOperation instead of a TypeError.
1177
Tim Petersecc6e6a2005-07-10 22:30:55 +00001178- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001179 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1180
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001181- Patch #1043890: Add extractall method to tarfile.
1182
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001183- Patch #1075887: Don't require MSVC in distutils if there is nothing
1184 to build.
1185
Martin v. Löwis637431b2005-03-03 23:12:42 +00001186- Patch #1103407: Properly deal with tarfile iterators when untarring
1187 symbolic links on Windows.
1188
Tim Petersecc6e6a2005-07-10 22:30:55 +00001189- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001190 profile.py if available.
1191
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001192- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1193
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001194- Patch #1117454: Remove code to special-case cookies without values
1195 in LWPCookieJar.
1196
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001197- Patch #1117339: Add cookielib special name tests.
1198
Martin v. Löwise869eb12005-03-03 09:46:07 +00001199- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1200
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001201- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1202
Martin v. Löwisdf241532005-03-03 08:17:42 +00001203- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1204
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001205- Patch #1104111: Alter setup.py --help and --help-commands.
1206
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001207- Patch #1121234: Properly cleanup _exit and tkerror commands.
1208
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001209- Patch #1049151: xdrlib now unpacks booleans as True or False.
1210
Raymond Hettingerbab41432005-02-05 01:31:19 +00001211- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1212
Guido van Rossumd0641422005-02-03 15:01:24 +00001213- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1214 disables recursive traversal through instance attributes, which can
1215 be exploited in various ways.
1216
Tim Peterse3547fd2005-12-16 23:13:57 +00001217- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001218 flags on the HTTP listening socket.
1219
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001220- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1221 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1222
Tim Peterse3547fd2005-12-16 23:13:57 +00001223- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001224 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1225
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001226- Bug #1110478: Revert os.environ.update to do putenv again.
1227
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001228- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1229
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001230- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1231
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001232- Enhancements to the csv module:
1233
1234 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001235 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001236 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001237 + Dialect parameter parsing has been re-implemented to improve error
1238 reporting.
1239 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1240 dictates.
1241 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001242 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001243 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001244 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1245 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001246 + reader now allows \r characters to be quoted (previously it only allowed
1247 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001248 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001249 + Dialect classes passed to the module are no longer instantiated by
1250 the module before being parsed (the former validation scheme required
1251 this, but the mechanism was unreliable).
1252 + The dialect registry now contains instances of the internal
1253 C-coded dialect type, rather than references to python objects.
1254 + the internal c-coded dialect type is now immutable.
1255 + register_dialect now accepts the same keyword dialect specifications
1256 as the reader and writer, allowing the user to register dialects
1257 without first creating a dialect class.
1258 + a configurable limit to the size of parsed fields has been added -
1259 previously, an unmatched quote character could result in the entire
1260 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001261 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001262 the parser field size limit (returning the former limit). The initial
1263 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001264 + A line_num attribute has been added to the reader object, which tracks
1265 the number of lines read from the source iterator. This is not
1266 the same as the number of records returned, as records can span
1267 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001268 + reader and writer objects were not being registered with the cyclic-GC.
1269 This has been fixed.
1270
Brett Cannone6539c42005-01-08 02:43:53 +00001271- _DummyThread objects in the threading module now delete self.__block that is
1272 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1273 lock primitives tend to be limited in number and thus should not be wasted on
1274 a _DummyThread object. Fixes bug #1089632.
1275
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001276- The imghdr module now detects Exif files.
1277
Raymond Hettinger6065d322004-12-20 23:51:53 +00001278- StringIO.truncate() now correctly adjusts the size attribute.
1279 (Bug #951915).
1280
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001281- locale.py now uses an updated locale alias table (built using
1282 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1283 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001284 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001285
Raymond Hettinger3557f422004-12-07 12:02:02 +00001286- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1287
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001288- the pickle module no longer accepts the deprecated None option in the
1289 args tuple returned by __reduce__().
1290
Brett Cannon84667c02004-12-07 03:25:18 +00001291- optparse now optionally imports gettext. This allows its use in setup.py.
1292
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001293- the pickle module no longer uses the deprecated bin parameter.
1294
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001295- the shelve module no longer uses the deprecated binary parameter.
1296
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001297- the pstats module no longer uses the deprecated ignore() method.
1298
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001299- the filecmp module no longer uses the deprecated use_statcache argument.
1300
Raymond Hettinger664347b2004-12-04 21:21:53 +00001301- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1302 extended or overridden by subclasses. Formerly, the subclassed method would
1303 be ignored by the rest of the module. (Bug #1078905).
1304
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001305- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001306 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001307
Walter Dörwald36733692004-12-22 12:50:50 +00001308- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1309 once when a size argument is given. This prevents a buffer overflow in the
1310 tokenizer with very long source lines.
1311
Barry Warsaw538561e2006-01-01 21:48:54 +00001312- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1313 immediately after creating the object, without any intervening
1314 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001315
Skip Montanaro05885812005-01-16 20:48:27 +00001316- The reconvert.quote function can now emit triple-quoted strings. The
1317 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001318
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001319- ``UserString.MutableString`` now supports negative indices in
1320 ``__setitem__`` and ``__delitem__``
1321
Greg Ward40407942005-03-05 02:53:17 +00001322- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1323 correctly.
1324
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001325- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1326 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1327 character even if the user has passed a size parameter to get a proper
1328 line ending. Remove the special handling of a "\r\n" that has been split
1329 between two lines.
1330
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001331- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1332 about illegal code points. The codec now supports PEP 293 style error
1333 handlers.
1334
Walter Dörwald78a78b02005-09-01 12:04:29 +00001335- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001336 from the input stream, so that the output is a byte string in the correct
1337 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001338
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001339- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1340 considering it exactly like a '*'.
1341
Walter Dörwald007f8df2005-10-09 19:42:27 +00001342- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1343 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001344
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001345- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1346
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001347- Patch #1413711: Certain patterns of differences were making difflib
1348 touch the recursion limit.
1349
Walter Dörwald58917a62006-03-31 15:26:22 +00001350- Bug #947906: An object oriented interface has been added to the calendar
1351 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001352 called as a script (e.g. via ``python -mcalendar``). Localized month and
1353 weekday names can be ouput (even if an exotic encoding is used) using
1354 special classes that use unicode.

1363
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001364- Build support for Win64-AMD64 was added.
1365
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001366- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1367
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001368- Patch #881820: look for openpty and forkpty also in libbsd.
1369
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001370- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1371 The zlib module is now builtin on Windows.
1372
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001373- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1374
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001375- Bug #1189330: configure did not correctly determine the necessary
1376 value of LINKCC if python was built with GCC 4.0.
1377
Trent Mick8321b422005-07-26 02:29:21 +00001378- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1379 vulnerability in zlib 1.2.1 and 1.2.2.
1380
Brett Cannon08cd5982005-04-24 22:26:38 +00001381- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1382 flags that change binary compatibility. Changes were also made to
1383 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001384 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001385
Bob Ippolitoed233462005-03-29 13:47:59 +00001386- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1387 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1388 no longer exists). This configure patch makes things right.
1389
Martin v. Löwise2713be2005-03-08 15:03:08 +00001390- Bug #1158607: Build with --disable-unicode again.
1391
Brett Cannon46d96232005-02-16 00:07:19 +00001392- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1393 defined. Discovered as a result of not being able to build on OS X.
1394
Brett Cannon516592f2004-12-07 00:42:59 +00001395- setup.py now uses the directories specified in LDFLAGS using the -L option
1396 and in CPPFLAGS using the -I option for adding library and include
1397 directories, respectively, for compiling extension modules against. This has
1398 led to the core being compiled using the values in CPPFLAGS. It also removes
1399 the need for the special-casing of both DarwinPorts and Fink for darwin since
1400 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1401 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1402 Fink, ``-I/opt/local/include`` for DarwinPorts).
1403
Brett Cannon43802422005-02-10 20:48:03 +00001404- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1405 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1406 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1407 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00001412- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1413 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1414 is obtained via the ``PyObject_`` family, it must be released via the
1415 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1416 always been officially true, but when Python's small-object allocator was
1417 introduced, an attempt was made to cater to a few extension modules
1418 discovered at the time that obtained memory via ``PyObject_New`` but
1419 released it via ``PyMem_DEL``. It's years later, and if such code still
1420 exists it will fail now (probably with segfaults, but calling wrong
1421 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00001423- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001427- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1428 mapping argument now. This string is used as a mapping table. Byte values
1429 greater than the length of the string and 0xFFFE are treated as undefined
1430 mappings.
