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. Smith372b5832006-06-05 18:48:21 +0000122
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000123Library
124-------
125
Tim Petersd6a9eef2006-06-05 01:48:21 +0000126- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
127 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000128
Martin v. Löwis3f767792006-06-04 19:36:28 +0000129- Patch #1359618: Speed up charmap encoder by using a trie structure
130 for lookup.
131
Tim Petersd609b1a2006-06-02 23:22:51 +0000132- The functions in the ``pprint`` module now sort dictionaries by key
133 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
134 if and only if its display required more than one line, although that
135 wasn't documented. The new behavior increases predictability; e.g.,
136 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
137
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000138- Patch #1497027: try HTTP digest auth before basic auth in urllib2
139 (thanks for J. J. Lee).
140
Georg Brandl2b330372006-05-28 20:23:12 +0000141- Patch #1496206: improve urllib2 handling of passwords with respect to
142 default HTTP and HTTPS ports.
143
George Yoshidaf3c65de2006-05-28 16:39:09 +0000144- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
145
Bob Ippolito7298f272006-05-23 18:43:47 +0000146- Patch #1281707: speed up gzip.readline.
147
Georg Brandlb89316f2006-05-17 15:51:16 +0000148- Patch #1180296: Two new functions were added to the locale module:
149 format_string() to get the effect of "format % items" but locale-aware,
150 and currency() to format a monetary number with currency sign.
151
Georg Brandle3a25832006-05-17 14:56:04 +0000152- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
153 and several features added, such as speed and geometry control.
154
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000155- Patch #1488881: add support for external file objects in bz2 compressed
156 tarfiles.
157
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000158- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
159 stdout arguments, making it possible to redirect input and output
160 for remote debugging.
161
162- Patch #1484695: Update the tarfile module to version 0.8. This fixes
163 a couple of issues, notably handling of long file names using the
164 GNU LONGNAME extension.
165
166- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
167 new flag when ``name`` is already the name of an option flag.
168
169- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
170 package.
171
172- Patch #1472854: make the rlcompleter.Completer class usable on non-
173 UNIX platforms.
174
175- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
176
177Build

181
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000182- Patch #1492356: Port to Windows CE.
183
Neal Norwitz58e28882006-05-19 07:00:58 +0000184- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
185
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000186- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000202What's New in Python 2.5 alpha 2?
203=================================
204
205*Release date: 27-APR-2006*
206
207Core and builtins
208-----------------
209
Thomas Heller1b046642006-04-18 18:51:06 +0000210- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
211 by converting these apis from macros into exported functions again:
212
213 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
214 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
215 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
216 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
217 PyRun_String Py_CompileString
218
Martin v. Löwis45294a92006-04-18 06:24:08 +0000219- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
220
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000221- All uses of PyStructSequence_InitType have been changed to initialize
222 the type objects only once, even if the interpreter is initialized
223 multiple times.
224
Neal Norwitz61546162006-04-14 05:20:28 +0000225- Bug #1454485, array.array('u') could crash the interpreter. This was
226 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
227 to unicode when it didn't make sense. 'u#' now requires a unicode string.
228
229- Py_UNICODE is unsigned. It was always documented as unsigned, but
230 due to a bug had a signed value in previous versions.
231
Tim Peters3a5e8b12006-04-11 01:44:07 +0000232- Patch #837242: ``id()`` of any Python object always gives a positive
233 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
234 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000235 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000236 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000237
Tim Peters3a5e8b12006-04-11 01:44:07 +0000238 def __hash__(self):
239 return id(self) # WRONG
240
241 because a hash result must be a (short) Python int but it was always
242 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000243 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000244 was always usable as a hash value before this patch. That's no longer
245 necessarily so.
246
247- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000248 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000249 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000250 #1454844)
251
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000252- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
253 involving generators that have paused outside of any ``try`` or ``with``
254 blocks. (In 2.5a1, a paused generator that was part of a reference
255 cycle could not be garbage collected, regardless of whether it was
256 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000258Extension Modules
259-----------------
260
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000261- Patch #1191065: Fix preprocessor problems on systems where recvfrom
262 is a macro.
263
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000264- Bug #1467952: os.listdir() now correctly raises an error if readdir()
265 fails with an error condition.
266
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000267- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
268
269- Bug #1117761: bsddb.*open() no longer raises an exception when using
270 the cachesize parameter.
271
272- Bug #1149413: bsddb.*open() no longer raises an exception when using
273 a temporary db (file=None) with the 'n' flag to truncate on open.
274
275- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
276 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000277
Armin Rigoa9017c32006-04-19 11:50:27 +0000278- Patch #1062014: AF_UNIX sockets under Linux have a special
279 abstract namespace that is now fully supported.
280
Anthony Baxter51bcb682006-04-05 14:51:42 +0000281Library
282-------
283
Tim Peters711bf302006-04-25 03:31:36 +0000284- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
285 a doctest to be skipped (the code is not run, and the expected output
286 or exception is ignored).
287
Nick Coghlanda2268f2006-04-24 04:37:15 +0000288- Fixed contextlib.nested to cope with exceptions being raised and
289 caught inside exit handlers.
290
Greg Wardab05edc2006-04-23 03:47:58 +0000291- Updated optparse module to Optik 1.5.1 (allow numeric constants in
292 hex, octal, or binary; add ``append_const`` action; keep going if
293 gettext cannot be imported; added ``OptionParser.destroy()`` method;
294 added ``epilog`` for better help generation).
295
Tim Peters21fbd572006-04-21 21:18:10 +0000296- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
297 called from a thread spawned as a side effect of importing a module.
298
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000299- The pydoc module now supports documenting packages contained in
300 .zip or .egg files.
301
302- The pkgutil module now has several new utility functions, such
303 as ``walk_packages()`` to support working with packages that are either
304 in the filesystem or zip files.
305
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000306- The mailbox module can now modify and delete messages from
307 mailboxes, in addition to simply reading them. Thanks to Gregory
308 K. Johnson for writing the code, and to the 2005 Google Summer of
309 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000310
Tim Petersc7605f22006-04-17 21:12:33 +0000311- The ``__del__`` method of class ``local`` in module ``_threading_local``
312 returned before accomplishing any of its intended cleanup.
313
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000314- Patch #790710: Add breakpoint command lists in pdb.
315
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000316- Patch #1063914: Add Tkinter.Misc.clipboard_get().
317
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000318- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
319
Anthony Baxtere29002c2006-04-12 12:07:31 +0000320- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
321 Windows. Bug #1469163.
322
Phillip J. Eby47032112006-04-11 01:07:43 +0000323- The warnings, linecache, inspect, traceback, site, and doctest modules
324 were updated to work correctly with modules imported from zipfiles or
325 via other PEP 302 __loader__ objects.
326
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000327- Patch #1467770: Reduce usage of subprocess._active to processes which
328 the application hasn't waited on.

338-----
339
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000340- The Makefile now has a reindent target, which runs reindent.py on
341 the library.
342
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000343- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000346
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000347- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
348 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000349 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000350 CXX from --with-cxx-main, see description in README.
351
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000352- Patch #1429775: Link extension modules with the shared libpython.
353
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000354- Fixed a libffi build problem on MIPS systems.
355
Tim Peters8931ff12006-05-13 23:28:20 +0000356- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
357 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
358 and "%zu" for unsigned integers of type ``size_t``.
359
Anthony Baxter51bcb682006-04-05 14:51:42 +0000360Tests
361-----
362
Nick Coghlanda2268f2006-04-24 04:37:15 +0000363- test_contextlib now checks contextlib.nested can cope with exceptions
364 being raised and caught inside exit handlers.
365
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000366- test_cmd_line now checks operation of the -m and -c command switches
367
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000368- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
369 it separately and by hand. It also wasn't cleaning up its changes to
370 the current Decimal context.
371
Thomas Woutersabd08882006-04-26 15:53:30 +0000372- regrtest.py now has a -M option to run tests that test the new limits of
373 containers, on 64-bit architectures. Running these tests is only sensible
374 on 64-bit machines with more than two gigabytes of memory. The argument
375 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000383Documentation
384-------------
385
Tim Petersb06d28c2006-05-12 01:57:59 +0000386- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
387
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000388- PEP 343: Added Context Types section to the library reference
389 and attempted to bring other PEP 343 related documentation into
390 line with the implementation and/or python-dev discussions.
391
Tim Peters8dc73d22006-04-24 02:03:16 +0000392- Bug #1337990: clarified that ``doctest`` does not support examples
393 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000396What's New in Python 2.5 alpha 1?
397=================================
398
Anthony Baxterebed3f62006-04-03 15:03:44 +0000399*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000400
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000401Core and builtins
402-----------------
403
Nick Coghlan43832302006-04-23 17:04:07 +0000404- PEP 338: -m command line switch now delegates to runpy.run_module
405 allowing it to support modules in packages and zipfiles
406
Martin v. Löwisc661b882006-04-20 04:54:23 +0000407- On Windows, .DLL is not an accepted file name extension for
408 extension modules anymore; extensions are only found if they
409 end in .PYD.
410
Martin v. Löwisea62d252006-04-03 10:56:49 +0000411- Bug #1421664: sys.stderr.encoding is now set to the same value as
412 sys.stdout.encoding.
413
Neal Norwitz92e212f2006-04-03 04:48:37 +0000414- __import__ accepts keyword arguments.
415
Georg Brandlccadf842006-03-31 18:54:53 +0000416- Patch #1460496: round() now accepts keyword arguments.
417
Anthony Baxter262c00a2006-03-30 10:53:17 +0000418- Fixed bug #1459029 - unicode reprs were double-escaped.
419
Hye-Shik Changd478f342006-03-23 12:32:36 +0000420- Patch #1396919: The system scope threads are reenabled on FreeBSD
421 5.4 and later versions.
422
Neal Norwitze98ccf62006-03-23 05:39:47 +0000423- Bug #1115379: Compiling a Unicode string with an encoding declaration
424 now gives a SyntaxError.
425
Georg Brandlabd1ff82006-03-18 07:59:59 +0000426- Previously, Python code had no easy way to access the contents of a
427 cell object. Now, a ``cell_contents`` attribute has been added
428 (closes patch #1170323).
429
Tim Peterscf79aac2006-03-16 01:14:46 +0000430- Patch #1123430: Python's small-object allocator now returns an arena to
431 the system ``free()`` when all memory within an arena becomes unused
432 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
433 freed. Some applications will see a drop in virtual memory size now,
434 especially long-running applications that, from time to time, temporarily
435 use a large number of small objects. Note that when Python returns an
436 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000437 platform C library will in turn return that memory to the operating system.
438 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000439 appears to be effective at least on Microsoft C and gcc-based systems.
440 Thanks to Evan Jones for hard work and patience.
441
Georg Brandl533ff6f2006-03-08 18:09:27 +0000442- Patch #1434038: property() now uses the getter's docstring if there is
443 no "doc" argument given. This makes it possible to legitimately use
444 property() as a decorator to produce a read-only property.
445
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000446- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
447 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
448 of requiring an int or long in slicing and a few other contexts, enabling
449 other objects (e.g. Numeric Python's integers) to be used as slice indices.
450
Neal Norwitz995acdf2006-03-07 05:01:00 +0000451- Fixed various bugs reported by Coverity's Prevent tool.
452
Brett Cannonbf364092006-03-01 04:25:17 +0000453- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
454 new exception base class, BaseException, which has a new message attribute.
455 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
456 Raising a string exception now raises a DeprecationWarning.
457
Thomas Woutersfb609f42006-02-28 16:37:25 +0000458- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
459 explicitly relative, using 'from .module import name' to mean 'from the same
460 package as this module is in. Imports without dots still default to the
461 old relative-then-absolute, unless 'from __future__ import
462 absolute_import' is used.
463
Brett Cannona7446e32006-02-27 23:39:10 +0000464- Properly check if 'warnings' raises an exception (usually when a filter set
465 to "error" is triggered) when raising a warning for raising string
466 exceptions.
467
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000468- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000469 The name was removed from Include/code.h.
470
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000471- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000472
Guido van Rossum1968ad32006-02-25 22:38:04 +0000473- Patch 1433928:
474 - The copy module now "copies" function objects (as atomic objects).
475 - dict.__getitem__ now looks for a __missing__ hook before raising
476 KeyError.
477
Tim Peters84ef21c2006-02-28 20:39:06 +0000478- PEP 343: with statement implemented. Needs ``from __future__ import
479 with_statement``. Use of 'with' as a variable will generate a warning.
480 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000481 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000482 The following objects have __context__ methods:
483 - The built-in file type.
484 - The thread.LockType type.
485 - The following types defined by the threading module:
486 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
487 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000488
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000489- Fix the encodings package codec search function to only search
490 inside its own package. Fixes problem reported in patch #1433198.
491
492 Note: Codec packages should implement and register their own
493 codec search function. PEP 100 has the details.
494
Tim Peters9ea89d22006-06-04 03:26:02 +0000495- PEP 353: Using ``Py_ssize_t`` as the index type.
496
497- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
498 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
499 now allow Python to make use of memory blocks exceeding 2**32 bytes for
500 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
501 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000502
Neal Norwitzfc76d632006-01-10 06:03:13 +0000503- Patch #1400181, fix unicode string formatting to not use the locale.
504 This is how string objects work. u'%f' could use , instead of .
505 for the decimal point. Now both strings and unicode always use periods.
506
Neal Norwitz671b9e32006-01-09 07:07:12 +0000507- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
508 configure would break checking curses.h.
509
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000510- Bug #959576: The pwd module is now builtin. This allows Python to be
511 built on UNIX platforms without $HOME set.
512
Neal Norwitzc10978f2005-12-19 06:07:16 +0000513- Bug #1072182, fix some potential problems if characters are signed.
514
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000515- Bug #889500, fix line number on SyntaxWarning for global declarations.
516
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000517- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
518
Neal Norwitze7214a12005-12-18 05:03:17 +0000519- Support for converting hex strings to floats no longer works.
520 This was not portable. float('0x3') now raises a ValueError.
521
Barry Warsaw2a38a862005-12-18 01:27:35 +0000522- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000523 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000524 is now displayed in interactive prompt banner.
525
Georg Brandlfa166682005-12-17 21:45:17 +0000526- Implementation of PEP 341 - Unification of try/except and try/finally.
527 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000528 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000529
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000530- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
531 now encodes backslash correctly.
532
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000533- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
534
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000535- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000536 and long longs.
537
Neal Norwitz67715f02005-11-09 06:59:35 +0000538- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000539 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000540 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000541
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000542- Replaced most Unicode charmap codecs with new ones using the
543 new Unicode translate string feature in the builtin charmap
544 codec; the codecs were created from the mapping tables available
545 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
546 encodings now include a mapping for the Apple logo)
547
Tim Peterse3547fd2005-12-16 23:13:57 +0000548- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000549
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000550- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000551
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000552- A new AST parser implementation was completed. The abstract
553 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000554 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000556- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000557 The following code now raises a SyntaxError: foo(a = i for i in range(10))
558
Neal Norwitz708e51a2005-10-03 04:48:15 +0000559- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
560
Neal Norwitz11bd1192005-10-03 00:54:56 +0000561- SF Bug #887946: fix segfault when redirecting stdin from a directory.
562 Provide a warning when a directory is passed on the command line.
563
Neal Norwitz40d37812005-10-02 01:48:49 +0000564- Fix segfault with invalid coding.
565
566- SF bug #772896: unknown encoding results in MemoryError.
567
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000568- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000569 supported a __len__() method which evaluated to False when the iterator
570 was empty.
571
Guido van Rossum630db602005-09-20 18:49:54 +0000572- On 64-bit platforms, when __len__() returns a value that cannot be
573 represented as a C int, raise OverflowError.
574
Skip Montanarof8948ca2005-09-19 03:54:46 +0000575- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000576 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000577
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000578- SF bug #893549: parsing keyword arguments was broken with a few format
579 codes.
580
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000581- Changes donated by Elemental Security to make it work on AIX 5.3
582 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
583 bug #105470: test_pwd fails on 64bit system (Opteron).
584
Guido van Rossum539c6622005-09-14 17:49:54 +0000585- Changes donated by Elemental Security to make it work on HP-UX 11 on
586 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
587
Georg Brandl4550b8d2005-08-26 06:43:52 +0000588- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000589 (fixes bug #1119418).
590
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000591- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
592
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000593- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
594 exceptions that cause a function to exit.
595
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000596- The implementation of set() and frozenset() was revised to use its
597 own internal data structure. Memory consumption is reduced by 1/3
598 and there are modest speed-ups as well. The API is unchanged.
599
Tim Petersde7990b2005-07-17 23:45:23 +0000600- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
601
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000602- SF bug #1229429: PyObject_CallMethod failed to decrement some
603 reference counts in some error exit cases.
604
Tim Petersecc6e6a2005-07-10 22:30:55 +0000605- SF bug #1185883: Python's small-object memory allocator took over
606 a block managed by the platform C library whenever a realloc specified
607 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000608 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000609 portable way to copy data from the C-managed block into Python's
610 small-object space without risking a memory fault. Python's small-object
611 realloc now leaves such blocks under the control of the platform C
612 realloc.
613
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000614- SF bug #1232517: An overflow error was not detected properly when
615 attempting to convert a large float to an int in os.utime().
616
Raymond Hettinger3296e692005-06-29 23:29:56 +0000617- SF bug #1224347: hex longs now print with lowercase letters just
618 like their int counterparts.
619
Michael W. Hudson188d4362005-06-20 16:52:57 +0000620- SF bug #1163563: the original fix for bug #1010677 ("thread Module
621 Breaks PyGILState_Ensure()") broke badly in the case of multiple
622 interpreter states; back out that fix and do a better job (see
623 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
624 for a longer write-up of the problem).
625
Michael W. Hudsondf888462005-06-03 14:41:55 +0000626- SF patch #1180995: marshal now uses a binary format by default when
627 serializing floats.
628
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000629- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
630 the routines that promise to produce IEEE 754 binary representations
631 of floats now simply copy bytes around.
632
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000633- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
634 278.
635
Brett Cannonc3647ac2005-04-26 03:45:26 +0000636- patch #1109424: int, long, float, complex, and unicode now check for the
637 proper magic slot for type conversions when subclassed. Previously the
638 magic slot was ignored during conversion. Semantics now match the way
639 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000640 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000641 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000642 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000643
Barry Warsawc8d907c2005-04-19 23:43:40 +0000644- Descriptors defined in C with a PyGetSetDef structure, where the setter is
645 NULL, now raise an AttributeError when attempting to set or delete the
646 attribute. Previously a TypeError was raised, but this was inconsistent
647 with the equivalent pure-Python implementation.
648
Michael W. Hudson774479c2005-04-18 08:46:17 +0000649- It is now safe to call PyGILState_Release() before
650 PyEval_InitThreads() (note that if there is reason to believe there
651 are multiple threads around you still must call PyEval_InitThreads()
652 before using the Python API; this fix is for extension modules that
653 have no way of knowing if Python is multi-threaded yet).
654
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000655- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
656 disabled caused a crash.
657
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000658- Bug #1165306: instancemethod_new allowed the creation of a method
659 with im_class == im_self == NULL, which caused a crash when called.
660
Tim Petersecc6e6a2005-07-10 22:30:55 +0000661- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000662 fixes the crash seen in bug #1165761
663
Raymond Hettinger96229b12005-03-11 06:49:40 +0000664- Added two new builtins, any() and all().
665
Brett Cannon409d8f22005-03-05 06:47:57 +0000666- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000667 (e.g., ``class C(): pass`` is no longer a syntax error).
668 Patch #1176012 added support to the 'parser' module and 'compiler' package
669 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000670
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000671- Patch #1115086: Support PY_LONGLONG in structmember.
672
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000673- Bug #1155938: new style classes did not check that __init__() was
674 returning None.
675
Tim Petersecc6e6a2005-07-10 22:30:55 +0000676- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000677 ('\') with a specific error message.
678
Martin v. Löwisff232d72005-03-03 09:24:38 +0000679- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
680
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000681- Bug #1124295: the __name__ attribute of file objects was
682 inadvertently made inaccessible in restricted mode.
683
Tim Petersecc6e6a2005-07-10 22:30:55 +0000684- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000685 an ferror() call.
686
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000687- min() and max() now support key= arguments with the same meaning as in
688 list.sort().
689
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000690- The peephole optimizer now performs simple constant folding in expressions:
691 (2+3) --> (5).
692
Raymond Hettingera422c342005-01-11 03:03:27 +0000693- set and frozenset objects can now be marshalled. SF #1098985.
694
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000695- Bug #1077106: Poor argument checking could cause memory corruption
696 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000697
Jeremy Hyltonab630502005-02-04 18:44:06 +0000698- The parser did not complain about future statements in illegal
699 positions. It once again reports a syntax error if a future
700 statement occurs after anything other than a doc string.
701
Neil Schemenauercf52c072005-08-12 17:34:58 +0000702- Change the %s format specifier for str objects so that it returns a
703 unicode instance if the argument is not an instance of basestring and
704 calling __str__ on the argument returns a unicode instance.
705
Tim Petersf4e69282006-02-27 17:15:31 +0000706- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
707 current thread state when the auto-GIL-state machinery knows about
708 it (since the thread state is being deleted, continuing to remember it
709 can't help, but can hurt if another thread happens to get created with
710 the same thread id).
711
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000712Extension Modules

729
730- The following modules were removed: regsub, reconvert, regex, regex_syntax.
731
732- re and sre were swapped, so help(re) provides full help. importing sre

736 SS2 (single-shift 2) escape sequences correctly.
737
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000738- The unicodedata module was updated to the 4.1 version of the Unicode
739 database. The 3.2 version is still available as unicodedata.db_3_2_0
740 for applications that require this specific version (such as IDNA).
741
Neal Norwitzb62c4332006-03-04 18:35:47 +0000742- The timing module is no longer built by default. It was deprecated
743 in PEP 4 in Python 2.0 or earlier.
744
Guido van Rossum1968ad32006-02-25 22:38:04 +0000745- Patch 1433928: Added a new type, defaultdict, to the collections module.

747
Georg Brandldbd83392006-02-20 09:42:33 +0000748- Bug #854823: socketmodule now builds on Sun platforms even when

750
Georg Brandlf4f44152006-02-18 22:29:33 +0000751- Patch #1393157: os.startfile() now has an optional argument to specify
752 a "command verb" to invoke on the file.
753
Neal Norwitz082b2df2006-02-07 07:04:46 +0000754- Bug #876637, prevent stack corruption when socket descriptor

760
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000761- Patch #1422385: The nis module now supports access to domains other
762 than the system default domain.
763
Martin v. Löwis14694662006-02-03 12:54:16 +0000764- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps

Raymond Hettingerb2594052004-12-05 09:25:51 +0000889- itertools.islice() now accepts None for the start and step arguments.
890 This allows islice() to work more readily with slices:
891 islice(s.start, s.stop, s.step)
892

900-------
901
Nick Coghlan43832302006-04-23 17:04:07 +0000902- PEP 338: new module runpy defines a run_module function to support
903 executing modules which provide access to source code or a code object
904 via the PEP 302 import mechanisms.
905
Anthony Baxter93f5b932006-04-03 08:05:07 +0000906- The email module's parsedate_tz function now sets the daylight savings
907 flag to -1 (unknown) since it can't tell from the date whether it should
908 be set.
909

914 in attribute values.
915
Anthony Baxterc51ee692006-04-01 00:57:31 +0000916- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000917 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000918 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000919 module will not be built.
920
Tim Petersc17976e2006-04-01 00:26:53 +0000921- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
922 aren't officially supported here, and trying to use them will probably
923 raise an exception some day. But dicts have been allowed, and "mostly
924 worked", so support for them won't go away without warning.
925
Georg Brandl338ef7d2006-03-31 18:42:16 +0000926- Bug #1445068: getpass.getpass() can now be given an explicit stream
927 argument to specify where to write the prompt.
928
Georg Brandl22ec80b2006-03-31 18:25:44 +0000929- Patch #1462313, bug #1443328: the pickle modules now can handle classes

935 key to be used for signing the uploaded code.
936
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000937- Queue.Queue objects now support .task_done() and .join() methods
938 to make it easier to monitor when daemon threads have completed
939 processing all enqueued tasks. Patch #1455676.
940
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000941- popen2.Popen objects now preserve the command in a .cmd attribute.
942

944
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000945- email 4.0 package now integrated. This is largely the same as the email 3.0
946 package that was included in Python 2.3, except that PEP 8 module names are
947 now used (e.g. mail.message instead of email.Message). The MIME classes
948 have been moved to a subpackage (e.g. email.mime.text instead of
949 email.MIMEText). The old names are still supported for now. Several
950 deprecated Message methods have been removed and lots of bugs have been
951 fixed. More details can be found in the email package documentation.
952
Walter Dörwald40108c92006-03-27 08:15:44 +0000953- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
954 (a subclass of tuple) that provides incremental decoders and encoders
955 (a way to use stateful codecs without the stream API). Python functions
956 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
957 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
958 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000959
Walter Dörwald067db482006-03-15 22:17:27 +0000960- Patch #1359365: Calling next() on a closed StringIO.String object raises
961 a ValueError instead of a StopIteration now (like file and cString.String do).
962 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
963 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000964
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000965- A regrtest option -w was added to re-run failed tests in verbose mode.

971 grew an optional 'generation' argument.
972
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000973- A library msilib to generate Windows Installer files, and a distutils

991 current file number.
992
Georg Brandl602b9ba2006-02-19 13:26:36 +0000993- Patch #1349274: gettext.install() now optionally installs additional

1039 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1040 Ronald L. Rivest offered this advice for Python:
1041
1042 "The consensus of researchers in this area (at least as
1043 expressed at the NIST Hash Function Workshop 10/31/05),
1044 is that SHA-256 is a good choice for the time being, but
1045 that research should continue, and other alternatives may
1046 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001047
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001048- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl268e61c2005-06-03 14:28:50 +00001150- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1151 component of the path.
1152
Skip Montanaro174dd222005-05-14 20:54:16 +00001153- Patch #1120353: The xmlrpclib module provides better, more transparent,
1154 support for datetime.{datetime,date,time} objects. With use_datetime set
1155 to True, applications shouldn't have to fiddle with the DateTime wrapper
1156 class at all.
1157
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001158- distutils.commands.upload was added to support uploading distribution
1159 files to PyPI.
1160
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001161- distutils.commands.register now encodes the data as UTF-8 before posting
1162 them to PyPI.
1163
Raymond Hettinger267b8682005-03-27 10:47:39 +00001164- decimal operator and comparison methods now return NotImplemented
1165 instead of raising a TypeError when interacting with other types. This
1166 allows other classes to implement __radd__ style methods and have them
1167 work as expected.
1168
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001169- Bug #1163325: Decimal infinities failed to hash. Attempting to
1170 hash a NaN raised an InvalidOperation instead of a TypeError.
1171
Tim Petersecc6e6a2005-07-10 22:30:55 +00001172- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001173 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1174
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001175- Patch #1043890: Add extractall method to tarfile.
1176
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001177- Patch #1075887: Don't require MSVC in distutils if there is nothing
1178 to build.
1179
Martin v. Löwis637431b2005-03-03 23:12:42 +00001180- Patch #1103407: Properly deal with tarfile iterators when untarring
1181 symbolic links on Windows.
1182
Tim Petersecc6e6a2005-07-10 22:30:55 +00001183- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001184 profile.py if available.
1185
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001186- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1187
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001188- Patch #1117454: Remove code to special-case cookies without values
1189 in LWPCookieJar.
1190
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001191- Patch #1117339: Add cookielib special name tests.
1192
Martin v. Löwise869eb12005-03-03 09:46:07 +00001193- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1194
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001195- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1196
Martin v. Löwisdf241532005-03-03 08:17:42 +00001197- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1198
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001199- Patch #1104111: Alter setup.py --help and --help-commands.
1200
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001201- Patch #1121234: Properly cleanup _exit and tkerror commands.
1202
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001203- Patch #1049151: xdrlib now unpacks booleans as True or False.
1204
Raymond Hettingerbab41432005-02-05 01:31:19 +00001205- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1206
Guido van Rossumd0641422005-02-03 15:01:24 +00001207- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1208 disables recursive traversal through instance attributes, which can
1209 be exploited in various ways.
1210
Tim Peterse3547fd2005-12-16 23:13:57 +00001211- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001212 flags on the HTTP listening socket.
1213
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001214- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1215 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1216
Tim Peterse3547fd2005-12-16 23:13:57 +00001217- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001218 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1219
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001220- Bug #1110478: Revert os.environ.update to do putenv again.
1221
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001222- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1223
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001224- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1225
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001226- Enhancements to the csv module:
1227
1228 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001229 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001230 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001231 + Dialect parameter parsing has been re-implemented to improve error
1232 reporting.
1233 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1234 dictates.
1235 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001236 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001237 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001238 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1239 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001240 + reader now allows \r characters to be quoted (previously it only allowed
1241 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001242 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001243 + Dialect classes passed to the module are no longer instantiated by
1244 the module before being parsed (the former validation scheme required
1245 this, but the mechanism was unreliable).
1246 + The dialect registry now contains instances of the internal
1247 C-coded dialect type, rather than references to python objects.
1248 + the internal c-coded dialect type is now immutable.
1249 + register_dialect now accepts the same keyword dialect specifications
1250 as the reader and writer, allowing the user to register dialects
1251 without first creating a dialect class.
1252 + a configurable limit to the size of parsed fields has been added -
1253 previously, an unmatched quote character could result in the entire
1254 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001255 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001256 the parser field size limit (returning the former limit). The initial
1257 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001258 + A line_num attribute has been added to the reader object, which tracks
1259 the number of lines read from the source iterator. This is not
1260 the same as the number of records returned, as records can span
1261 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001262 + reader and writer objects were not being registered with the cyclic-GC.
1263 This has been fixed.
1264
Brett Cannone6539c42005-01-08 02:43:53 +00001265- _DummyThread objects in the threading module now delete self.__block that is
1266 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1267 lock primitives tend to be limited in number and thus should not be wasted on
1268 a _DummyThread object. Fixes bug #1089632.
1269
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001270- The imghdr module now detects Exif files.
1271
Raymond Hettinger6065d322004-12-20 23:51:53 +00001272- StringIO.truncate() now correctly adjusts the size attribute.
1273 (Bug #951915).
1274
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001275- locale.py now uses an updated locale alias table (built using
1276 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1277 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001278 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001279
Raymond Hettinger3557f422004-12-07 12:02:02 +00001280- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1281
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001282- the pickle module no longer accepts the deprecated None option in the
1283 args tuple returned by __reduce__().
1284
Brett Cannon84667c02004-12-07 03:25:18 +00001285- optparse now optionally imports gettext. This allows its use in setup.py.
1286
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001287- the pickle module no longer uses the deprecated bin parameter.
1288
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001289- the shelve module no longer uses the deprecated binary parameter.
1290
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001291- the pstats module no longer uses the deprecated ignore() method.
1292
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001293- the filecmp module no longer uses the deprecated use_statcache argument.
1294
Raymond Hettinger664347b2004-12-04 21:21:53 +00001295- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1296 extended or overridden by subclasses. Formerly, the subclassed method would
1297 be ignored by the rest of the module. (Bug #1078905).
1298
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001299- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001300 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001301
Walter Dörwald36733692004-12-22 12:50:50 +00001302- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1303 once when a size argument is given. This prevents a buffer overflow in the
1304 tokenizer with very long source lines.
1305
Barry Warsaw538561e2006-01-01 21:48:54 +00001306- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1307 immediately after creating the object, without any intervening
1308 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001309
Skip Montanaro05885812005-01-16 20:48:27 +00001310- The reconvert.quote function can now emit triple-quoted strings. The
1311 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001312
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001313- ``UserString.MutableString`` now supports negative indices in
1314 ``__setitem__`` and ``__delitem__``
1315
Greg Ward40407942005-03-05 02:53:17 +00001316- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1317 correctly.
1318
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001319- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1320 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1321 character even if the user has passed a size parameter to get a proper
1322 line ending. Remove the special handling of a "\r\n" that has been split
1323 between two lines.
1324
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001325- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1326 about illegal code points. The codec now supports PEP 293 style error
1327 handlers.
1328
Walter Dörwald78a78b02005-09-01 12:04:29 +00001329- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001330 from the input stream, so that the output is a byte string in the correct
1331 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001332
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001333- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1334 considering it exactly like a '*'.
1335
Walter Dörwald007f8df2005-10-09 19:42:27 +00001336- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1337 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001338
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001339- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1340
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001341- Patch #1413711: Certain patterns of differences were making difflib
1342 touch the recursion limit.
1343
Walter Dörwald58917a62006-03-31 15:26:22 +00001344- Bug #947906: An object oriented interface has been added to the calendar
1345 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001346 called as a script (e.g. via ``python -mcalendar``). Localized month and
1347 weekday names can be ouput (even if an exotic encoding is used) using
1348 special classes that use unicode.

1351-----
1352
Neal Norwitz602d3392006-03-31 08:21:40 +00001353- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1354 by using -mieee gcc option.
1355
Martin v. Löwis86d66262006-02-17 08:40:11 +00001356- Patch #1432345: Make python compile on DragonFly.
1357
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001358- Build support for Win64-AMD64 was added.
1359
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001360- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1361
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001362- Patch #881820: look for openpty and forkpty also in libbsd.
1363
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001364- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1365 The zlib module is now builtin on Windows.
1366
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001367- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1368
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001369- Bug #1189330: configure did not correctly determine the necessary
1370 value of LINKCC if python was built with GCC 4.0.
1371
Trent Mick8321b422005-07-26 02:29:21 +00001372- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1373 vulnerability in zlib 1.2.1 and 1.2.2.
1374
Brett Cannon08cd5982005-04-24 22:26:38 +00001375- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1376 flags that change binary compatibility. Changes were also made to
1377 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001378 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001379
Bob Ippolitoed233462005-03-29 13:47:59 +00001380- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1381 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1382 no longer exists). This configure patch makes things right.
1383
Martin v. Löwise2713be2005-03-08 15:03:08 +00001384- Bug #1158607: Build with --disable-unicode again.
1385
Brett Cannon46d96232005-02-16 00:07:19 +00001386- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1387 defined. Discovered as a result of not being able to build on OS X.
1388
Brett Cannon516592f2004-12-07 00:42:59 +00001389- setup.py now uses the directories specified in LDFLAGS using the -L option
1390 and in CPPFLAGS using the -I option for adding library and include
1391 directories, respectively, for compiling extension modules against. This has
1392 led to the core being compiled using the values in CPPFLAGS. It also removes
1393 the need for the special-casing of both DarwinPorts and Fink for darwin since
1394 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1395 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1396 Fink, ``-I/opt/local/include`` for DarwinPorts).
1397
Brett Cannon43802422005-02-10 20:48:03 +00001398- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1399 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1400 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1401 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001403C API
1404-----
1405
Tim Petersc9d78aa2006-03-26 23:27:58 +00001406- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1407 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1408 is obtained via the ``PyObject_`` family, it must be released via the
1409 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1410 always been officially true, but when Python's small-object allocator was
1411 introduced, an attempt was made to cater to a few extension modules
1412 discovered at the time that obtained memory via ``PyObject_New`` but
1413 released it via ``PyMem_DEL``. It's years later, and if such code still
1414 exists it will fail now (probably with segfaults, but calling wrong
