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. Smithf0547d02006-06-05 17:38:04 +0000112- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class
113 [pybsddb project SF patch number 1466734]
114
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000115Library
116-------
117
Tim Petersd6a9eef2006-06-05 01:48:21 +0000118- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
119 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000120
Martin v. Löwis3f767792006-06-04 19:36:28 +0000121- Patch #1359618: Speed up charmap encoder by using a trie structure
122 for lookup.
123
Tim Petersd609b1a2006-06-02 23:22:51 +0000124- The functions in the ``pprint`` module now sort dictionaries by key
125 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
126 if and only if its display required more than one line, although that
127 wasn't documented. The new behavior increases predictability; e.g.,
128 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
129
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000130- Patch #1497027: try HTTP digest auth before basic auth in urllib2
131 (thanks for J. J. Lee).
132
Georg Brandl2b330372006-05-28 20:23:12 +0000133- Patch #1496206: improve urllib2 handling of passwords with respect to
134 default HTTP and HTTPS ports.
135
George Yoshidaf3c65de2006-05-28 16:39:09 +0000136- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
137
Bob Ippolito7298f272006-05-23 18:43:47 +0000138- Patch #1281707: speed up gzip.readline.
139
Georg Brandlb89316f2006-05-17 15:51:16 +0000140- Patch #1180296: Two new functions were added to the locale module:
141 format_string() to get the effect of "format % items" but locale-aware,
142 and currency() to format a monetary number with currency sign.
143
Georg Brandle3a25832006-05-17 14:56:04 +0000144- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
145 and several features added, such as speed and geometry control.
146
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000147- Patch #1488881: add support for external file objects in bz2 compressed
148 tarfiles.
149
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000150- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
151 stdout arguments, making it possible to redirect input and output
152 for remote debugging.
153
154- Patch #1484695: Update the tarfile module to version 0.8. This fixes
155 a couple of issues, notably handling of long file names using the
156 GNU LONGNAME extension.
157
158- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
159 new flag when ``name`` is already the name of an option flag.
160
161- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
162 package.
163
164- Patch #1472854: make the rlcompleter.Completer class usable on non-
165 UNIX platforms.
166
167- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000194What's New in Python 2.5 alpha 2?
195=================================
196
197*Release date: 27-APR-2006*
198
199Core and builtins
200-----------------
201
Thomas Heller1b046642006-04-18 18:51:06 +0000202- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
203 by converting these apis from macros into exported functions again:
204
205 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
206 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
207 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
208 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
209 PyRun_String Py_CompileString
210
Martin v. Löwis45294a92006-04-18 06:24:08 +0000211- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
212
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000213- All uses of PyStructSequence_InitType have been changed to initialize
214 the type objects only once, even if the interpreter is initialized
215 multiple times.
216
Neal Norwitz61546162006-04-14 05:20:28 +0000217- Bug #1454485, array.array('u') could crash the interpreter. This was
218 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
219 to unicode when it didn't make sense. 'u#' now requires a unicode string.
220
221- Py_UNICODE is unsigned. It was always documented as unsigned, but
222 due to a bug had a signed value in previous versions.
223
Tim Peters3a5e8b12006-04-11 01:44:07 +0000224- Patch #837242: ``id()`` of any Python object always gives a positive
225 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
226 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000227 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000228 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000229
Tim Peters3a5e8b12006-04-11 01:44:07 +0000230 def __hash__(self):
231 return id(self) # WRONG
232
233 because a hash result must be a (short) Python int but it was always
234 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000235 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000236 was always usable as a hash value before this patch. That's no longer
237 necessarily so.
238
239- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000240 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000241 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000242 #1454844)
243
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000244- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
245 involving generators that have paused outside of any ``try`` or ``with``
246 blocks. (In 2.5a1, a paused generator that was part of a reference
247 cycle could not be garbage collected, regardless of whether it was
248 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000250Extension Modules
251-----------------
252
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000253- Patch #1191065: Fix preprocessor problems on systems where recvfrom
254 is a macro.
255
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000256- Bug #1467952: os.listdir() now correctly raises an error if readdir()
257 fails with an error condition.
258
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000259- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
260
261- Bug #1117761: bsddb.*open() no longer raises an exception when using
262 the cachesize parameter.
263
264- Bug #1149413: bsddb.*open() no longer raises an exception when using
265 a temporary db (file=None) with the 'n' flag to truncate on open.
266
267- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
268 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000269
Armin Rigoa9017c32006-04-19 11:50:27 +0000270- Patch #1062014: AF_UNIX sockets under Linux have a special
271 abstract namespace that is now fully supported.

274-------
275
Tim Peters711bf302006-04-25 03:31:36 +0000276- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
277 a doctest to be skipped (the code is not run, and the expected output
278 or exception is ignored).
279
Nick Coghlanda2268f2006-04-24 04:37:15 +0000280- Fixed contextlib.nested to cope with exceptions being raised and
281 caught inside exit handlers.
282
Greg Wardab05edc2006-04-23 03:47:58 +0000283- Updated optparse module to Optik 1.5.1 (allow numeric constants in
284 hex, octal, or binary; add ``append_const`` action; keep going if
285 gettext cannot be imported; added ``OptionParser.destroy()`` method;
286 added ``epilog`` for better help generation).
287
Tim Peters21fbd572006-04-21 21:18:10 +0000288- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
289 called from a thread spawned as a side effect of importing a module.
290
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000291- The pydoc module now supports documenting packages contained in
292 .zip or .egg files.
293
294- The pkgutil module now has several new utility functions, such
295 as ``walk_packages()`` to support working with packages that are either
296 in the filesystem or zip files.
297
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000298- The mailbox module can now modify and delete messages from
299 mailboxes, in addition to simply reading them. Thanks to Gregory
300 K. Johnson for writing the code, and to the 2005 Google Summer of
301 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000302
Tim Petersc7605f22006-04-17 21:12:33 +0000303- The ``__del__`` method of class ``local`` in module ``_threading_local``
304 returned before accomplishing any of its intended cleanup.
305
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000306- Patch #790710: Add breakpoint command lists in pdb.
307
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000308- Patch #1063914: Add Tkinter.Misc.clipboard_get().
309
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000310- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
311
Anthony Baxtere29002c2006-04-12 12:07:31 +0000312- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
313 Windows. Bug #1469163.
314
Phillip J. Eby47032112006-04-11 01:07:43 +0000315- The warnings, linecache, inspect, traceback, site, and doctest modules
316 were updated to work correctly with modules imported from zipfiles or
317 via other PEP 302 __loader__ objects.
318
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000319- Patch #1467770: Reduce usage of subprocess._active to processes which
320 the application hasn't waited on.
321
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000322- Patch #1462222: Fix Tix.Grid.

330-----
331
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000332- The Makefile now has a reindent target, which runs reindent.py on

334
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000335- Patch #1470875: Building Python with MS Free Compiler
336
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000337- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000338
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000339- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
340 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000341 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000342 CXX from --with-cxx-main, see description in README.
343
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000344- Patch #1429775: Link extension modules with the shared libpython.
345
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000346- Fixed a libffi build problem on MIPS systems.
347
Tim Peters8931ff12006-05-13 23:28:20 +0000348- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
349 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
350 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000352Tests
353-----
354
Nick Coghlanda2268f2006-04-24 04:37:15 +0000355- test_contextlib now checks contextlib.nested can cope with exceptions
356 being raised and caught inside exit handlers.
357
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000358- test_cmd_line now checks operation of the -m and -c command switches
359
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000360- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
361 it separately and by hand. It also wasn't cleaning up its changes to
362 the current Decimal context.
363
Thomas Woutersabd08882006-04-26 15:53:30 +0000364- regrtest.py now has a -M option to run tests that test the new limits of
365 containers, on 64-bit architectures. Running these tests is only sensible
366 on 64-bit machines with more than two gigabytes of memory. The argument
367 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000375Documentation
376-------------
377
Tim Petersb06d28c2006-05-12 01:57:59 +0000378- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
379
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000380- PEP 343: Added Context Types section to the library reference
381 and attempted to bring other PEP 343 related documentation into
382 line with the implementation and/or python-dev discussions.
383
Tim Peters8dc73d22006-04-24 02:03:16 +0000384- Bug #1337990: clarified that ``doctest`` does not support examples
385 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000388What's New in Python 2.5 alpha 1?
389=================================
390
Anthony Baxterebed3f62006-04-03 15:03:44 +0000391*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000392
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000393Core and builtins
394-----------------
395
Nick Coghlan43832302006-04-23 17:04:07 +0000396- PEP 338: -m command line switch now delegates to runpy.run_module
397 allowing it to support modules in packages and zipfiles
398
Martin v. Löwisc661b882006-04-20 04:54:23 +0000399- On Windows, .DLL is not an accepted file name extension for
400 extension modules anymore; extensions are only found if they
401 end in .PYD.
402
Martin v. Löwisea62d252006-04-03 10:56:49 +0000403- Bug #1421664: sys.stderr.encoding is now set to the same value as
404 sys.stdout.encoding.
405
Neal Norwitz92e212f2006-04-03 04:48:37 +0000406- __import__ accepts keyword arguments.
407
Georg Brandlccadf842006-03-31 18:54:53 +0000408- Patch #1460496: round() now accepts keyword arguments.
409
Anthony Baxter262c00a2006-03-30 10:53:17 +0000410- Fixed bug #1459029 - unicode reprs were double-escaped.
411
Hye-Shik Changd478f342006-03-23 12:32:36 +0000412- Patch #1396919: The system scope threads are reenabled on FreeBSD
413 5.4 and later versions.
414
Neal Norwitze98ccf62006-03-23 05:39:47 +0000415- Bug #1115379: Compiling a Unicode string with an encoding declaration
416 now gives a SyntaxError.
417
Georg Brandlabd1ff82006-03-18 07:59:59 +0000418- Previously, Python code had no easy way to access the contents of a
419 cell object. Now, a ``cell_contents`` attribute has been added
420 (closes patch #1170323).
421
Tim Peterscf79aac2006-03-16 01:14:46 +0000422- Patch #1123430: Python's small-object allocator now returns an arena to
423 the system ``free()`` when all memory within an arena becomes unused
424 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
425 freed. Some applications will see a drop in virtual memory size now,
426 especially long-running applications that, from time to time, temporarily
427 use a large number of small objects. Note that when Python returns an
428 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000429 platform C library will in turn return that memory to the operating system.
430 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000431 appears to be effective at least on Microsoft C and gcc-based systems.
432 Thanks to Evan Jones for hard work and patience.
433
Georg Brandl533ff6f2006-03-08 18:09:27 +0000434- Patch #1434038: property() now uses the getter's docstring if there is
435 no "doc" argument given. This makes it possible to legitimately use
436 property() as a decorator to produce a read-only property.
437
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000438- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
439 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
440 of requiring an int or long in slicing and a few other contexts, enabling
441 other objects (e.g. Numeric Python's integers) to be used as slice indices.
442
Neal Norwitz995acdf2006-03-07 05:01:00 +0000443- Fixed various bugs reported by Coverity's Prevent tool.
444
Brett Cannonbf364092006-03-01 04:25:17 +0000445- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
446 new exception base class, BaseException, which has a new message attribute.
447 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
448 Raising a string exception now raises a DeprecationWarning.
449
Thomas Woutersfb609f42006-02-28 16:37:25 +0000450- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
451 explicitly relative, using 'from .module import name' to mean 'from the same
452 package as this module is in. Imports without dots still default to the
453 old relative-then-absolute, unless 'from __future__ import
454 absolute_import' is used.
455
Brett Cannona7446e32006-02-27 23:39:10 +0000456- Properly check if 'warnings' raises an exception (usually when a filter set
457 to "error" is triggered) when raising a warning for raising string
458 exceptions.
459
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000460- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000461 The name was removed from Include/code.h.
462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000463- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000464
Guido van Rossum1968ad32006-02-25 22:38:04 +0000465- Patch 1433928:
466 - The copy module now "copies" function objects (as atomic objects).
467 - dict.__getitem__ now looks for a __missing__ hook before raising
468 KeyError.
469
Tim Peters84ef21c2006-02-28 20:39:06 +0000470- PEP 343: with statement implemented. Needs ``from __future__ import
471 with_statement``. Use of 'with' as a variable will generate a warning.
472 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000473 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000474 The following objects have __context__ methods:
475 - The built-in file type.
476 - The thread.LockType type.
477 - The following types defined by the threading module:
478 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
479 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000480
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000481- Fix the encodings package codec search function to only search
482 inside its own package. Fixes problem reported in patch #1433198.
483
484 Note: Codec packages should implement and register their own
485 codec search function. PEP 100 has the details.
486
Tim Peters9ea89d22006-06-04 03:26:02 +0000487- PEP 353: Using ``Py_ssize_t`` as the index type.
488
489- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
490 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
491 now allow Python to make use of memory blocks exceeding 2**32 bytes for
492 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
493 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000494
Neal Norwitzfc76d632006-01-10 06:03:13 +0000495- Patch #1400181, fix unicode string formatting to not use the locale.
496 This is how string objects work. u'%f' could use , instead of .
497 for the decimal point. Now both strings and unicode always use periods.
498
Neal Norwitz671b9e32006-01-09 07:07:12 +0000499- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
500 configure would break checking curses.h.
501
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000502- Bug #959576: The pwd module is now builtin. This allows Python to be
503 built on UNIX platforms without $HOME set.
504
Neal Norwitzc10978f2005-12-19 06:07:16 +0000505- Bug #1072182, fix some potential problems if characters are signed.
506
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000507- Bug #889500, fix line number on SyntaxWarning for global declarations.
508
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000509- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
510
Neal Norwitze7214a12005-12-18 05:03:17 +0000511- Support for converting hex strings to floats no longer works.
512 This was not portable. float('0x3') now raises a ValueError.
513
Barry Warsaw2a38a862005-12-18 01:27:35 +0000514- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000515 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000516 is now displayed in interactive prompt banner.
517
Georg Brandlfa166682005-12-17 21:45:17 +0000518- Implementation of PEP 341 - Unification of try/except and try/finally.
519 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000520 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000521
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000522- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
523 now encodes backslash correctly.
524
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000525- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
526
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000527- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000528 and long longs.
529
Neal Norwitz67715f02005-11-09 06:59:35 +0000530- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000531 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000532 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000533
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000534- Replaced most Unicode charmap codecs with new ones using the
535 new Unicode translate string feature in the builtin charmap
536 codec; the codecs were created from the mapping tables available
537 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
538 encodings now include a mapping for the Apple logo)
539
Tim Peterse3547fd2005-12-16 23:13:57 +0000540- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000541
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000542- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000543
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000544- A new AST parser implementation was completed. The abstract
545 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000546 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000548- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000549 The following code now raises a SyntaxError: foo(a = i for i in range(10))
550
Neal Norwitz708e51a2005-10-03 04:48:15 +0000551- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
552
Neal Norwitz11bd1192005-10-03 00:54:56 +0000553- SF Bug #887946: fix segfault when redirecting stdin from a directory.
554 Provide a warning when a directory is passed on the command line.
555
Neal Norwitz40d37812005-10-02 01:48:49 +0000556- Fix segfault with invalid coding.
557
558- SF bug #772896: unknown encoding results in MemoryError.
559
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000560- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000561 supported a __len__() method which evaluated to False when the iterator
562 was empty.
563
Guido van Rossum630db602005-09-20 18:49:54 +0000564- On 64-bit platforms, when __len__() returns a value that cannot be
565 represented as a C int, raise OverflowError.
566
Skip Montanarof8948ca2005-09-19 03:54:46 +0000567- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000568 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000569
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000570- SF bug #893549: parsing keyword arguments was broken with a few format
571 codes.
572
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000573- Changes donated by Elemental Security to make it work on AIX 5.3
574 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
575 bug #105470: test_pwd fails on 64bit system (Opteron).
576
Guido van Rossum539c6622005-09-14 17:49:54 +0000577- Changes donated by Elemental Security to make it work on HP-UX 11 on
578 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
579
Georg Brandl4550b8d2005-08-26 06:43:52 +0000580- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000581 (fixes bug #1119418).
582
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000583- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
584
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000585- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
586 exceptions that cause a function to exit.
587
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000588- The implementation of set() and frozenset() was revised to use its
589 own internal data structure. Memory consumption is reduced by 1/3
590 and there are modest speed-ups as well. The API is unchanged.
591
Tim Petersde7990b2005-07-17 23:45:23 +0000592- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
593
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000594- SF bug #1229429: PyObject_CallMethod failed to decrement some
595 reference counts in some error exit cases.
596
Tim Petersecc6e6a2005-07-10 22:30:55 +0000597- SF bug #1185883: Python's small-object memory allocator took over
598 a block managed by the platform C library whenever a realloc specified
599 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000600 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000601 portable way to copy data from the C-managed block into Python's
602 small-object space without risking a memory fault. Python's small-object
603 realloc now leaves such blocks under the control of the platform C
604 realloc.
605
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000606- SF bug #1232517: An overflow error was not detected properly when
607 attempting to convert a large float to an int in os.utime().
608
Raymond Hettinger3296e692005-06-29 23:29:56 +0000609- SF bug #1224347: hex longs now print with lowercase letters just
610 like their int counterparts.
611
Michael W. Hudson188d4362005-06-20 16:52:57 +0000612- SF bug #1163563: the original fix for bug #1010677 ("thread Module
613 Breaks PyGILState_Ensure()") broke badly in the case of multiple
614 interpreter states; back out that fix and do a better job (see
615 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
616 for a longer write-up of the problem).
617
Michael W. Hudsondf888462005-06-03 14:41:55 +0000618- SF patch #1180995: marshal now uses a binary format by default when
619 serializing floats.
620
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000621- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
622 the routines that promise to produce IEEE 754 binary representations
623 of floats now simply copy bytes around.
624
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000625- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
626 278.
627
Brett Cannonc3647ac2005-04-26 03:45:26 +0000628- patch #1109424: int, long, float, complex, and unicode now check for the
629 proper magic slot for type conversions when subclassed. Previously the
630 magic slot was ignored during conversion. Semantics now match the way
631 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000632 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000633 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000634 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000635
Barry Warsawc8d907c2005-04-19 23:43:40 +0000636- Descriptors defined in C with a PyGetSetDef structure, where the setter is
637 NULL, now raise an AttributeError when attempting to set or delete the
638 attribute. Previously a TypeError was raised, but this was inconsistent
639 with the equivalent pure-Python implementation.
640
Michael W. Hudson774479c2005-04-18 08:46:17 +0000641- It is now safe to call PyGILState_Release() before
642 PyEval_InitThreads() (note that if there is reason to believe there
643 are multiple threads around you still must call PyEval_InitThreads()
644 before using the Python API; this fix is for extension modules that
645 have no way of knowing if Python is multi-threaded yet).
646
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000647- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
648 disabled caused a crash.
649
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000650- Bug #1165306: instancemethod_new allowed the creation of a method
651 with im_class == im_self == NULL, which caused a crash when called.
652
Tim Petersecc6e6a2005-07-10 22:30:55 +0000653- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000654 fixes the crash seen in bug #1165761
655
Raymond Hettinger96229b12005-03-11 06:49:40 +0000656- Added two new builtins, any() and all().
657
Brett Cannon409d8f22005-03-05 06:47:57 +0000658- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000659 (e.g., ``class C(): pass`` is no longer a syntax error).
660 Patch #1176012 added support to the 'parser' module and 'compiler' package
661 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000662
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000663- Patch #1115086: Support PY_LONGLONG in structmember.
664
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000665- Bug #1155938: new style classes did not check that __init__() was
666 returning None.
667
Tim Petersecc6e6a2005-07-10 22:30:55 +0000668- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000669 ('\') with a specific error message.
670
Martin v. Löwisff232d72005-03-03 09:24:38 +0000671- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
672
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000673- Bug #1124295: the __name__ attribute of file objects was
674 inadvertently made inaccessible in restricted mode.
675
Tim Petersecc6e6a2005-07-10 22:30:55 +0000676- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000677 an ferror() call.
678
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000679- min() and max() now support key= arguments with the same meaning as in
680 list.sort().
681
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000682- The peephole optimizer now performs simple constant folding in expressions:
683 (2+3) --> (5).
684
Raymond Hettingera422c342005-01-11 03:03:27 +0000685- set and frozenset objects can now be marshalled. SF #1098985.
686
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000687- Bug #1077106: Poor argument checking could cause memory corruption
688 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000689
Jeremy Hyltonab630502005-02-04 18:44:06 +0000690- The parser did not complain about future statements in illegal
691 positions. It once again reports a syntax error if a future
692 statement occurs after anything other than a doc string.
693
Neil Schemenauercf52c072005-08-12 17:34:58 +0000694- Change the %s format specifier for str objects so that it returns a
695 unicode instance if the argument is not an instance of basestring and
696 calling __str__ on the argument returns a unicode instance.
697
Tim Petersf4e69282006-02-27 17:15:31 +0000698- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
699 current thread state when the auto-GIL-state machinery knows about
700 it (since the thread state is being deleted, continuing to remember it
701 can't help, but can hurt if another thread happens to get created with
702 the same thread id).
703
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000704Extension Modules

729
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000730- The unicodedata module was updated to the 4.1 version of the Unicode
731 database. The 3.2 version is still available as unicodedata.db_3_2_0
732 for applications that require this specific version (such as IDNA).
733
Neal Norwitzb62c4332006-03-04 18:35:47 +0000734- The timing module is no longer built by default. It was deprecated
735 in PEP 4 in Python 2.0 or earlier.
736
Guido van Rossum1968ad32006-02-25 22:38:04 +0000737- Patch 1433928: Added a new type, defaultdict, to the collections module.

739
Georg Brandldbd83392006-02-20 09:42:33 +0000740- Bug #854823: socketmodule now builds on Sun platforms even when

892-------
893
Nick Coghlan43832302006-04-23 17:04:07 +0000894- PEP 338: new module runpy defines a run_module function to support
895 executing modules which provide access to source code or a code object
896 via the PEP 302 import mechanisms.
897
Anthony Baxter93f5b932006-04-03 08:05:07 +0000898- The email module's parsedate_tz function now sets the daylight savings
899 flag to -1 (unknown) since it can't tell from the date whether it should
900 be set.
901
Fred Drakead5177c2006-04-01 22:14:43 +0000902- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
903 now sport attributes that provide access to the parts of the result.

906 in attribute values.
907
Anthony Baxterc51ee692006-04-01 00:57:31 +0000908- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000909 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000910 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000911 module will not be built.
912
Tim Petersc17976e2006-04-01 00:26:53 +0000913- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
914 aren't officially supported here, and trying to use them will probably
915 raise an exception some day. But dicts have been allowed, and "mostly
916 worked", so support for them won't go away without warning.
917
Georg Brandl338ef7d2006-03-31 18:42:16 +0000918- Bug #1445068: getpass.getpass() can now be given an explicit stream
919 argument to specify where to write the prompt.
920
Georg Brandl22ec80b2006-03-31 18:25:44 +0000921- Patch #1462313, bug #1443328: the pickle modules now can handle classes

927 key to be used for signing the uploaded code.
928
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000929- Queue.Queue objects now support .task_done() and .join() methods
930 to make it easier to monitor when daemon threads have completed
931 processing all enqueued tasks. Patch #1455676.
932
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000933- popen2.Popen objects now preserve the command in a .cmd attribute.
934
Thomas Hellerc61c0492006-03-22 10:09:27 +0000935- Added the ctypes ffi package.
936
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000937- email 4.0 package now integrated. This is largely the same as the email 3.0
938 package that was included in Python 2.3, except that PEP 8 module names are
939 now used (e.g. mail.message instead of email.Message). The MIME classes
940 have been moved to a subpackage (e.g. email.mime.text instead of
941 email.MIMEText). The old names are still supported for now. Several
942 deprecated Message methods have been removed and lots of bugs have been
943 fixed. More details can be found in the email package documentation.
944
Walter Dörwald40108c92006-03-27 08:15:44 +0000945- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
946 (a subclass of tuple) that provides incremental decoders and encoders
947 (a way to use stateful codecs without the stream API). Python functions
948 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
949 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
950 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000951
Walter Dörwald067db482006-03-15 22:17:27 +0000952- Patch #1359365: Calling next() on a closed StringIO.String object raises
953 a ValueError instead of a StopIteration now (like file and cString.String do).
954 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
955 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000956
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000957- A regrtest option -w was added to re-run failed tests in verbose mode.

960 interpreter to exit.
961

963 grew an optional 'generation' argument.
964
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000965- A library msilib to generate Windows Installer files, and a distutils
966 command bdist_msi have been added.
967

969 and helpful context managers nested() and closing().
970
Martin v. Löwis415ed932006-02-27 19:56:30 +0000971- The compiler package now supports future imports after the module docstring.

1030 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1031 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1032 Ronald L. Rivest offered this advice for Python:
1033
1034 "The consensus of researchers in this area (at least as
1035 expressed at the NIST Hash Function Workshop 10/31/05),
1036 is that SHA-256 is a good choice for the time being, but
1037 that research should continue, and other alternatives may
1038 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001039
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001040- Added a subset of Fredrik Lundh's ElementTree package. Available

1154 them to PyPI.
1155
Raymond Hettinger267b8682005-03-27 10:47:39 +00001156- decimal operator and comparison methods now return NotImplemented
1157 instead of raising a TypeError when interacting with other types. This
1158 allows other classes to implement __radd__ style methods and have them
1159 work as expected.
1160
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001161- Bug #1163325: Decimal infinities failed to hash. Attempting to
1162 hash a NaN raised an InvalidOperation instead of a TypeError.
1163
Tim Petersecc6e6a2005-07-10 22:30:55 +00001164- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001165 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1166
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001167- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00001169- Patch #1075887: Don't require MSVC in distutils if there is nothing
1170 to build.
1171
Martin v. Löwis637431b2005-03-03 23:12:42 +00001172- Patch #1103407: Properly deal with tarfile iterators when untarring
1173 symbolic links on Windows.
1174
Tim Petersecc6e6a2005-07-10 22:30:55 +00001175- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001176 profile.py if available.
1177
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001178- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1179
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001180- Patch #1117454: Remove code to special-case cookies without values
1181 in LWPCookieJar.
1182
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001183- Patch #1117339: Add cookielib special name tests.

Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001187- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1188
Martin v. Löwisdf241532005-03-03 08:17:42 +00001189- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1190
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001191- Patch #1104111: Alter setup.py --help and --help-commands.
1192
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001193- Patch #1121234: Properly cleanup _exit and tkerror commands.
1194
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001195- Patch #1049151: xdrlib now unpacks booleans as True or False.
1196
Raymond Hettingerbab41432005-02-05 01:31:19 +00001197- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1198
Guido van Rossumd0641422005-02-03 15:01:24 +00001199- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1200 disables recursive traversal through instance attributes, which can
1201 be exploited in various ways.
1202
Tim Peterse3547fd2005-12-16 23:13:57 +00001203- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001204 flags on the HTTP listening socket.
1205
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001206- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1207 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1208
Tim Peterse3547fd2005-12-16 23:13:57 +00001209- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001210 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1211
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001212- Bug #1110478: Revert os.environ.update to do putenv again.
1213
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001214- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1215
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001216- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1217
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001218- Enhancements to the csv module:
1219
1220 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001221 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001222 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001223 + Dialect parameter parsing has been re-implemented to improve error
1224 reporting.
1225 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1226 dictates.
1227 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001228 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001229 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001230 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1231 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001232 + reader now allows \r characters to be quoted (previously it only allowed
1233 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001234 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001235 + Dialect classes passed to the module are no longer instantiated by
1236 the module before being parsed (the former validation scheme required
1237 this, but the mechanism was unreliable).
1238 + The dialect registry now contains instances of the internal
1239 C-coded dialect type, rather than references to python objects.
1240 + the internal c-coded dialect type is now immutable.
1241 + register_dialect now accepts the same keyword dialect specifications
1242 as the reader and writer, allowing the user to register dialects
1243 without first creating a dialect class.
1244 + a configurable limit to the size of parsed fields has been added -
1245 previously, an unmatched quote character could result in the entire
1246 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001247 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001248 the parser field size limit (returning the former limit). The initial
1249 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001250 + A line_num attribute has been added to the reader object, which tracks
1251 the number of lines read from the source iterator. This is not
1252 the same as the number of records returned, as records can span
1253 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001254 + reader and writer objects were not being registered with the cyclic-GC.
1255 This has been fixed.
1256
Brett Cannone6539c42005-01-08 02:43:53 +00001257- _DummyThread objects in the threading module now delete self.__block that is
1258 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1259 lock primitives tend to be limited in number and thus should not be wasted on
1260 a _DummyThread object. Fixes bug #1089632.
1261
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001262- The imghdr module now detects Exif files.
1263
Raymond Hettinger6065d322004-12-20 23:51:53 +00001264- StringIO.truncate() now correctly adjusts the size attribute.
1265 (Bug #951915).
1266
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001267- locale.py now uses an updated locale alias table (built using
1268 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1269 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001270 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001271
Raymond Hettinger3557f422004-12-07 12:02:02 +00001272- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1273
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001274- the pickle module no longer accepts the deprecated None option in the
1275 args tuple returned by __reduce__().
1276
Brett Cannon84667c02004-12-07 03:25:18 +00001277- optparse now optionally imports gettext. This allows its use in setup.py.
1278
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001279- the pickle module no longer uses the deprecated bin parameter.
1280
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001281- the shelve module no longer uses the deprecated binary parameter.
1282
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001283- the pstats module no longer uses the deprecated ignore() method.
1284
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001285- the filecmp module no longer uses the deprecated use_statcache argument.
1286
Raymond Hettinger664347b2004-12-04 21:21:53 +00001287- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1288 extended or overridden by subclasses. Formerly, the subclassed method would
1289 be ignored by the rest of the module. (Bug #1078905).
1290
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001291- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001292 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001293
Walter Dörwald36733692004-12-22 12:50:50 +00001294- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1295 once when a size argument is given. This prevents a buffer overflow in the
1296 tokenizer with very long source lines.
1297
Barry Warsaw538561e2006-01-01 21:48:54 +00001298- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1299 immediately after creating the object, without any intervening
1300 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001301
Skip Montanaro05885812005-01-16 20:48:27 +00001302- The reconvert.quote function can now emit triple-quoted strings. The
1303 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001304
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001305- ``UserString.MutableString`` now supports negative indices in
1306 ``__setitem__`` and ``__delitem__``
1307
Greg Ward40407942005-03-05 02:53:17 +00001308- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1309 correctly.
1310
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001311- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1312 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1313 character even if the user has passed a size parameter to get a proper
1314 line ending. Remove the special handling of a "\r\n" that has been split
1315 between two lines.
1316
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001317- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1318 about illegal code points. The codec now supports PEP 293 style error
1319 handlers.
1320
Walter Dörwald78a78b02005-09-01 12:04:29 +00001321- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001322 from the input stream, so that the output is a byte string in the correct
1323 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001324
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001325- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1326 considering it exactly like a '*'.
1327
Walter Dörwald007f8df2005-10-09 19:42:27 +00001328- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1329 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001330
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001331- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1332
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001333- Patch #1413711: Certain patterns of differences were making difflib
1334 touch the recursion limit.
1335
Walter Dörwald58917a62006-03-31 15:26:22 +00001336- Bug #947906: An object oriented interface has been added to the calendar
1337 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001338 called as a script (e.g. via ``python -mcalendar``). Localized month and
1339 weekday names can be ouput (even if an exotic encoding is used) using
1340 special classes that use unicode.

1349
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001350- Build support for Win64-AMD64 was added.
1351
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001352- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1353
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001354- Patch #881820: look for openpty and forkpty also in libbsd.
1355
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001356- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1357 The zlib module is now builtin on Windows.
1358
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001359- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1360
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001361- Bug #1189330: configure did not correctly determine the necessary
1362 value of LINKCC if python was built with GCC 4.0.
1363
Trent Mick8321b422005-07-26 02:29:21 +00001364- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1365 vulnerability in zlib 1.2.1 and 1.2.2.
1366
Brett Cannon08cd5982005-04-24 22:26:38 +00001367- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1368 flags that change binary compatibility. Changes were also made to
1369 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001370 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001371
Bob Ippolitoed233462005-03-29 13:47:59 +00001372- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1373 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1374 no longer exists). This configure patch makes things right.
1375
Martin v. Löwise2713be2005-03-08 15:03:08 +00001376- Bug #1158607: Build with --disable-unicode again.
1377
Brett Cannon46d96232005-02-16 00:07:19 +00001378- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1379 defined. Discovered as a result of not being able to build on OS X.
1380
Brett Cannon516592f2004-12-07 00:42:59 +00001381- setup.py now uses the directories specified in LDFLAGS using the -L option
1382 and in CPPFLAGS using the -I option for adding library and include
1383 directories, respectively, for compiling extension modules against. This has
1384 led to the core being compiled using the values in CPPFLAGS. It also removes
1385 the need for the special-casing of both DarwinPorts and Fink for darwin since
1386 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1387 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1388 Fink, ``-I/opt/local/include`` for DarwinPorts).
1389
Brett Cannon43802422005-02-10 20:48:03 +00001390- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1391 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1392 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1393 Closes bug #1096244. Thanks Gregory Bond.

1396-----
1397
Tim Petersc9d78aa2006-03-26 23:27:58 +00001398- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1399 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1400 is obtained via the ``PyObject_`` family, it must be released via the
1401 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1402 always been officially true, but when Python's small-object allocator was
1403 introduced, an attempt was made to cater to a few extension modules
1404 discovered at the time that obtained memory via ``PyObject_New`` but
1405 released it via ``PyMem_DEL``. It's years later, and if such code still
1406 exists it will fail now (probably with segfaults, but calling wrong
1407 low-level memory management functions can yield many symptoms).
1408
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001409- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001413- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1414 mapping argument now. This string is used as a mapping table. Byte values
1415 greater than the length of the string and 0xFFFE are treated as undefined
1416 mappings.
