Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================
9
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 Brandlb7c8f542006-05-27 12:30:25 +000015- Builtin exceptions are now full-blown new-style classes instead of
16 instances pretending to be classes, which speeds up exception handling
17 by about 80% in comparison to 2.5a2.
18
Martin v. Löwisd004fc82006-05-27 08:36:52 +000019- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
20 Unicode 4.1.
21
Georg Brandlf4ef1162006-05-26 18:03:31 +000022- Patch #921466: sys.path_importer_cache is now used to cache valid and
23 invalid file paths for the built-in import machinery which leads to
24 fewer open calls on startup.
25
Tim Peters696cf432006-05-24 21:10:40 +000026- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
27 of-2 bases. The largest speedup is for inputs with about 1000 decimal
28 digits. Conversion from non-power-of-2 bases remains quadratic-time in
29 the number of input digits (it was and remains linear-time for bases
30 2, 4, 8, 16 and 32).
31
Tim Petersb713ec22006-05-23 18:45:30 +000032- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
33 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
34 an integer close to ``sys.maxint``. This was repaired by patch
35 #1335972, which also gives a nice speedup.
36
Richard Jonescebbefc2006-05-23 18:28:17 +000037- Patch #1337051: reduced size of frame objects.
38
39- PyErr_NewException now accepts a tuple of base classes as its
40 "base" parameter.
41
Richard Jones7c88dcc2006-05-23 10:37:38 +000042- Patch #876206: function call speedup by retaining allocated frame
43 objects.
44
Georg Brandl7b90e162006-05-18 07:01:27 +000045- Bug #1462152: file() now checks more thoroughly for invalid mode
46 strings and removes a possible "U" before passing the mode to the
47 C library function.
48
Neal Norwitz1004a532006-05-15 07:17:23 +000049- Patch #1488312, Fix memory alignment problem on SPARC in unicode
50
Neal Norwitz373f0a72006-05-15 07:04:36 +000051- Bug #1487966: Fix SystemError with conditional expression in assignment
52
Martin v. Löwis879768d2006-05-11 13:28:43 +000053- WindowsError now has two error code attributes: errno, which carries
54 the error values from errno.h, and winerror, which carries the error
55 values from winerror.h. Previous versions put the winerror.h values
56 (from GetLastError()) into the errno attribute.
57
Martin v. Löwis77736712006-05-04 05:51:03 +000058- Patch #1475845: Raise IndentationError for unexpected indent.
59
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000060- Patch #1479181: split open() and file() from being aliases for each other.
61
Tim Peters44bd9862006-06-01 13:49:23 +000062- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
63 methods were always silently ignored by dictionaries when comparing keys.
64 They are now passed through (except when using the C API function
65 ``PyDict_GetItem()``, whose semantics did not change).
66
67- Bug #1456209: In some obscure cases it was possible for a class with a
68 custom ``__eq__()`` method to confuse dict internals when class instances
69 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
70 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000072Extension Modules
73-----------------
74
Nick Coghlanc649ec52006-05-29 12:43:05 +000075- Patch #1478788 (modified version): The functional extension module has
76 been renamed to _functools and a functools Python wrapper module added.
77 This provides a home for additional function related utilities that are
78 not specifically about functional programming. See PEP 309.
79
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000080- Patch #1493701: performance enhancements for struct module.
81
Georg Brandl378d5922006-05-17 14:26:50 +000082- Patch #1490224: time.altzone is now set correctly on Cygwin.
83
Georg Brandl8d3342b2006-05-16 07:38:27 +000084- Patch #1435422: zlib's compress and decompress objects now have a
85 copy() method.
86
Neal Norwitz7a5fc282006-05-15 06:48:14 +000087- On Win32, os.listdir now supports arbitrarily-long Unicode path names
88 (up to the system limit of 32K characters).
89
90- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
91 As a result, these functions now raise WindowsError instead of OSError.
92
Tim Peters7a822da2006-05-25 21:50:17 +000093- ``time.clock()`` on Win64 should use the high-performance Windows
94 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
95 Windows platforms).
96
Neal Norwitz7a5fc282006-05-15 06:48:14 +000097- Calling Tk_Init twice is refused if the first call failed as that
98 may deadlock.
99
Nick Coghlanc649ec52006-05-29 12:43:05 +0000100
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000101Library
102-------
103
Tim Petersd609b1a2006-06-02 23:22:51 +0000104- The functions in the ``pprint`` module now sort dictionaries by key
105 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
106 if and only if its display required more than one line, although that
107 wasn't documented. The new behavior increases predictability; e.g.,
108 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
109
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000110- Patch #1497027: try HTTP digest auth before basic auth in urllib2
111 (thanks for J. J. Lee).
112
Georg Brandl2b330372006-05-28 20:23:12 +0000113- Patch #1496206: improve urllib2 handling of passwords with respect to
114 default HTTP and HTTPS ports.
115
George Yoshidaf3c65de2006-05-28 16:39:09 +0000116- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
117
Bob Ippolito7298f272006-05-23 18:43:47 +0000118- Patch #1281707: speed up gzip.readline.
119
Georg Brandlb89316f2006-05-17 15:51:16 +0000120- Patch #1180296: Two new functions were added to the locale module:
121 format_string() to get the effect of "format % items" but locale-aware,
122 and currency() to format a monetary number with currency sign.
123
Georg Brandle3a25832006-05-17 14:56:04 +0000124- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
125 and several features added, such as speed and geometry control.
126
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000127- Patch #1488881: add support for external file objects in bz2 compressed
128 tarfiles.
129
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000130- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
131 stdout arguments, making it possible to redirect input and output
132 for remote debugging.
133
134- Patch #1484695: Update the tarfile module to version 0.8. This fixes
135 a couple of issues, notably handling of long file names using the
136 GNU LONGNAME extension.
137
138- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
139 new flag when ``name`` is already the name of an option flag.
140
141- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
142 package.
143
144- Patch #1472854: make the rlcompleter.Completer class usable on non-
145 UNIX platforms.
146
147- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000174What's New in Python 2.5 alpha 2?
175=================================
176
177*Release date: 27-APR-2006*
178
179Core and builtins
180-----------------
181
Thomas Heller1b046642006-04-18 18:51:06 +0000182- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
183 by converting these apis from macros into exported functions again:
184
185 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
186 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
187 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
188 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
189 PyRun_String Py_CompileString
190
Martin v. Löwis45294a92006-04-18 06:24:08 +0000191- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
192
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000193- All uses of PyStructSequence_InitType have been changed to initialize
194 the type objects only once, even if the interpreter is initialized
195 multiple times.
196
Neal Norwitz61546162006-04-14 05:20:28 +0000197- Bug #1454485, array.array('u') could crash the interpreter. This was
198 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
199 to unicode when it didn't make sense. 'u#' now requires a unicode string.
200
201- Py_UNICODE is unsigned. It was always documented as unsigned, but
202 due to a bug had a signed value in previous versions.
203
Tim Peters3a5e8b12006-04-11 01:44:07 +0000204- Patch #837242: ``id()`` of any Python object always gives a positive
205 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
206 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000207 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000208 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000209
Tim Peters3a5e8b12006-04-11 01:44:07 +0000210 def __hash__(self):
211 return id(self) # WRONG
212
213 because a hash result must be a (short) Python int but it was always
214 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000215 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000216 was always usable as a hash value before this patch. That's no longer
217 necessarily so.
218
219- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000220 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000221 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000222 #1454844)
223
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000224- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
225 involving generators that have paused outside of any ``try`` or ``with``
226 blocks. (In 2.5a1, a paused generator that was part of a reference
227 cycle could not be garbage collected, regardless of whether it was
228 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000230Extension Modules
231-----------------
232
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000233- Patch #1191065: Fix preprocessor problems on systems where recvfrom
234 is a macro.
235
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000236- Bug #1467952: os.listdir() now correctly raises an error if readdir()
237 fails with an error condition.
238
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000239- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
240
241- Bug #1117761: bsddb.*open() no longer raises an exception when using
242 the cachesize parameter.
243
244- Bug #1149413: bsddb.*open() no longer raises an exception when using
245 a temporary db (file=None) with the 'n' flag to truncate on open.
246
247- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
248 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000249
Armin Rigoa9017c32006-04-19 11:50:27 +0000250- Patch #1062014: AF_UNIX sockets under Linux have a special
251 abstract namespace that is now fully supported.
252
Anthony Baxter51bcb682006-04-05 14:51:42 +0000253Library
254-------
255
Tim Peters711bf302006-04-25 03:31:36 +0000256- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
257 a doctest to be skipped (the code is not run, and the expected output
258 or exception is ignored).
259
Nick Coghlanda2268f2006-04-24 04:37:15 +0000260- Fixed contextlib.nested to cope with exceptions being raised and
261 caught inside exit handlers.
262
Greg Wardab05edc2006-04-23 03:47:58 +0000263- Updated optparse module to Optik 1.5.1 (allow numeric constants in
264 hex, octal, or binary; add ``append_const`` action; keep going if
265 gettext cannot be imported; added ``OptionParser.destroy()`` method;
266 added ``epilog`` for better help generation).
267
Tim Peters21fbd572006-04-21 21:18:10 +0000268- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
269 called from a thread spawned as a side effect of importing a module.
270
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000271- The pydoc module now supports documenting packages contained in
272 .zip or .egg files.
273
274- The pkgutil module now has several new utility functions, such
275 as ``walk_packages()`` to support working with packages that are either
276 in the filesystem or zip files.
277
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000278- The mailbox module can now modify and delete messages from
279 mailboxes, in addition to simply reading them. Thanks to Gregory
280 K. Johnson for writing the code, and to the 2005 Google Summer of
281 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000282
Tim Petersc7605f22006-04-17 21:12:33 +0000283- The ``__del__`` method of class ``local`` in module ``_threading_local``
284 returned before accomplishing any of its intended cleanup.
285
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000286- Patch #790710: Add breakpoint command lists in pdb.
287
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000288- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000290- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
291
Anthony Baxtere29002c2006-04-12 12:07:31 +0000292- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
293 Windows. Bug #1469163.
294
Phillip J. Eby47032112006-04-11 01:07:43 +0000295- The warnings, linecache, inspect, traceback, site, and doctest modules
296 were updated to work correctly with modules imported from zipfiles or
297 via other PEP 302 __loader__ objects.
298

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000319- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
320 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000321 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000322 CXX from --with-cxx-main, see description in README.
323
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000324- Patch #1429775: Link extension modules with the shared libpython.
325
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000326- Fixed a libffi build problem on MIPS systems.
327
Tim Peters8931ff12006-05-13 23:28:20 +0000328- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
329 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
330 and "%zu" for unsigned integers of type ``size_t``.

333-----
334
Nick Coghlanda2268f2006-04-24 04:37:15 +0000335- test_contextlib now checks contextlib.nested can cope with exceptions
336 being raised and caught inside exit handlers.
337
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000338- test_cmd_line now checks operation of the -m and -c command switches
339
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000340- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
341 it separately and by hand. It also wasn't cleaning up its changes to
342 the current Decimal context.
343
Thomas Woutersabd08882006-04-26 15:53:30 +0000344- regrtest.py now has a -M option to run tests that test the new limits of
345 containers, on 64-bit architectures. Running these tests is only sensible
346 on 64-bit machines with more than two gigabytes of memory. The argument
347 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000355Documentation
356-------------
357
Tim Petersb06d28c2006-05-12 01:57:59 +0000358- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
359
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000360- PEP 343: Added Context Types section to the library reference
361 and attempted to bring other PEP 343 related documentation into
362 line with the implementation and/or python-dev discussions.
363
Tim Peters8dc73d22006-04-24 02:03:16 +0000364- Bug #1337990: clarified that ``doctest`` does not support examples
365 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000368What's New in Python 2.5 alpha 1?
369=================================
370
Anthony Baxterebed3f62006-04-03 15:03:44 +0000371*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000372
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000373Core and builtins
374-----------------
375
Nick Coghlan43832302006-04-23 17:04:07 +0000376- PEP 338: -m command line switch now delegates to runpy.run_module
377 allowing it to support modules in packages and zipfiles
378
Martin v. Löwisc661b882006-04-20 04:54:23 +0000379- On Windows, .DLL is not an accepted file name extension for
380 extension modules anymore; extensions are only found if they
381 end in .PYD.
382
Martin v. Löwisea62d252006-04-03 10:56:49 +0000383- Bug #1421664: sys.stderr.encoding is now set to the same value as
384 sys.stdout.encoding.
385
Neal Norwitz92e212f2006-04-03 04:48:37 +0000386- __import__ accepts keyword arguments.
387
Georg Brandlccadf842006-03-31 18:54:53 +0000388- Patch #1460496: round() now accepts keyword arguments.
389
Anthony Baxter262c00a2006-03-30 10:53:17 +0000390- Fixed bug #1459029 - unicode reprs were double-escaped.
391
Hye-Shik Changd478f342006-03-23 12:32:36 +0000392- Patch #1396919: The system scope threads are reenabled on FreeBSD
393 5.4 and later versions.
394
Neal Norwitze98ccf62006-03-23 05:39:47 +0000395- Bug #1115379: Compiling a Unicode string with an encoding declaration
396 now gives a SyntaxError.
397
Georg Brandlabd1ff82006-03-18 07:59:59 +0000398- Previously, Python code had no easy way to access the contents of a
399 cell object. Now, a ``cell_contents`` attribute has been added
400 (closes patch #1170323).
401
Tim Peterscf79aac2006-03-16 01:14:46 +0000402- Patch #1123430: Python's small-object allocator now returns an arena to
403 the system ``free()`` when all memory within an arena becomes unused
404 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
405 freed. Some applications will see a drop in virtual memory size now,
406 especially long-running applications that, from time to time, temporarily
407 use a large number of small objects. Note that when Python returns an
408 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000409 platform C library will in turn return that memory to the operating system.
410 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000411 appears to be effective at least on Microsoft C and gcc-based systems.
412 Thanks to Evan Jones for hard work and patience.
413
Georg Brandl533ff6f2006-03-08 18:09:27 +0000414- Patch #1434038: property() now uses the getter's docstring if there is
415 no "doc" argument given. This makes it possible to legitimately use
416 property() as a decorator to produce a read-only property.
417
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000418- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
419 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
420 of requiring an int or long in slicing and a few other contexts, enabling
421 other objects (e.g. Numeric Python's integers) to be used as slice indices.
422
Neal Norwitz995acdf2006-03-07 05:01:00 +0000423- Fixed various bugs reported by Coverity's Prevent tool.
424
Brett Cannonbf364092006-03-01 04:25:17 +0000425- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
426 new exception base class, BaseException, which has a new message attribute.
427 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
428 Raising a string exception now raises a DeprecationWarning.
429
Thomas Woutersfb609f42006-02-28 16:37:25 +0000430- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
431 explicitly relative, using 'from .module import name' to mean 'from the same
432 package as this module is in. Imports without dots still default to the
433 old relative-then-absolute, unless 'from __future__ import
434 absolute_import' is used.
435
Brett Cannona7446e32006-02-27 23:39:10 +0000436- Properly check if 'warnings' raises an exception (usually when a filter set
437 to "error" is triggered) when raising a warning for raising string
438 exceptions.
439
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000440- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000441 The name was removed from Include/code.h.
442
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000443- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000444
Guido van Rossum1968ad32006-02-25 22:38:04 +0000445- Patch 1433928:
446 - The copy module now "copies" function objects (as atomic objects).
447 - dict.__getitem__ now looks for a __missing__ hook before raising
448 KeyError.
449
Tim Peters84ef21c2006-02-28 20:39:06 +0000450- PEP 343: with statement implemented. Needs ``from __future__ import
451 with_statement``. Use of 'with' as a variable will generate a warning.
452 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000453 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000454 The following objects have __context__ methods:
455 - The built-in file type.
456 - The thread.LockType type.
457 - The following types defined by the threading module:
458 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
459 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000460
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000461- Fix the encodings package codec search function to only search
462 inside its own package. Fixes problem reported in patch #1433198.
463
464 Note: Codec packages should implement and register their own
465 codec search function. PEP 100 has the details.
466
Martin v. Löwis18e16552006-02-15 17:27:45 +0000467- PEP 353: Using ssize_t as the index type.
468
Neal Norwitzfc76d632006-01-10 06:03:13 +0000469- Patch #1400181, fix unicode string formatting to not use the locale.
470 This is how string objects work. u'%f' could use , instead of .
471 for the decimal point. Now both strings and unicode always use periods.
472
Neal Norwitz671b9e32006-01-09 07:07:12 +0000473- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
474 configure would break checking curses.h.
475
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000476- Bug #959576: The pwd module is now builtin. This allows Python to be
477 built on UNIX platforms without $HOME set.
478
Neal Norwitzc10978f2005-12-19 06:07:16 +0000479- Bug #1072182, fix some potential problems if characters are signed.
480
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000481- Bug #889500, fix line number on SyntaxWarning for global declarations.
482
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000483- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
484
Neal Norwitze7214a12005-12-18 05:03:17 +0000485- Support for converting hex strings to floats no longer works.
486 This was not portable. float('0x3') now raises a ValueError.
487
Barry Warsaw2a38a862005-12-18 01:27:35 +0000488- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000489 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000490 is now displayed in interactive prompt banner.
491
Georg Brandlfa166682005-12-17 21:45:17 +0000492- Implementation of PEP 341 - Unification of try/except and try/finally.
493 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000494 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000495
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000496- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
497 now encodes backslash correctly.
498
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000499- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
500
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000501- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000502 and long longs.
503
Neal Norwitz67715f02005-11-09 06:59:35 +0000504- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000505 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000506 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000507
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000508- Replaced most Unicode charmap codecs with new ones using the
509 new Unicode translate string feature in the builtin charmap
510 codec; the codecs were created from the mapping tables available
511 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
512 encodings now include a mapping for the Apple logo)
513
Tim Peterse3547fd2005-12-16 23:13:57 +0000514- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000515
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000516- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000517
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000518- A new AST parser implementation was completed. The abstract
519 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000520 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000521
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000522- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000523 The following code now raises a SyntaxError: foo(a = i for i in range(10))
524
Neal Norwitz708e51a2005-10-03 04:48:15 +0000525- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
526
Neal Norwitz11bd1192005-10-03 00:54:56 +0000527- SF Bug #887946: fix segfault when redirecting stdin from a directory.
528 Provide a warning when a directory is passed on the command line.
529
Neal Norwitz40d37812005-10-02 01:48:49 +0000530- Fix segfault with invalid coding.
531
532- SF bug #772896: unknown encoding results in MemoryError.
533
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000534- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000535 supported a __len__() method which evaluated to False when the iterator
536 was empty.
537
Guido van Rossum630db602005-09-20 18:49:54 +0000538- On 64-bit platforms, when __len__() returns a value that cannot be
539 represented as a C int, raise OverflowError.
540
Skip Montanarof8948ca2005-09-19 03:54:46 +0000541- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000542 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000543
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000544- SF bug #893549: parsing keyword arguments was broken with a few format
545 codes.
546
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000547- Changes donated by Elemental Security to make it work on AIX 5.3
548 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
549 bug #105470: test_pwd fails on 64bit system (Opteron).
550
Guido van Rossum539c6622005-09-14 17:49:54 +0000551- Changes donated by Elemental Security to make it work on HP-UX 11 on
552 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
553
Georg Brandl4550b8d2005-08-26 06:43:52 +0000554- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000555 (fixes bug #1119418).
556
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000557- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
558
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000559- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
560 exceptions that cause a function to exit.
561
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000562- The implementation of set() and frozenset() was revised to use its
563 own internal data structure. Memory consumption is reduced by 1/3
564 and there are modest speed-ups as well. The API is unchanged.
565
Tim Petersde7990b2005-07-17 23:45:23 +0000566- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
567
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000568- SF bug #1229429: PyObject_CallMethod failed to decrement some
569 reference counts in some error exit cases.
570
Tim Petersecc6e6a2005-07-10 22:30:55 +0000571- SF bug #1185883: Python's small-object memory allocator took over
572 a block managed by the platform C library whenever a realloc specified
573 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000574 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000575 portable way to copy data from the C-managed block into Python's
576 small-object space without risking a memory fault. Python's small-object
577 realloc now leaves such blocks under the control of the platform C
578 realloc.
579
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000580- SF bug #1232517: An overflow error was not detected properly when
581 attempting to convert a large float to an int in os.utime().
582
Raymond Hettinger3296e692005-06-29 23:29:56 +0000583- SF bug #1224347: hex longs now print with lowercase letters just
584 like their int counterparts.
585
Michael W. Hudson188d4362005-06-20 16:52:57 +0000586- SF bug #1163563: the original fix for bug #1010677 ("thread Module
587 Breaks PyGILState_Ensure()") broke badly in the case of multiple
588 interpreter states; back out that fix and do a better job (see
589 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
590 for a longer write-up of the problem).
591
Michael W. Hudsondf888462005-06-03 14:41:55 +0000592- SF patch #1180995: marshal now uses a binary format by default when
593 serializing floats.
594
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000595- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
596 the routines that promise to produce IEEE 754 binary representations
597 of floats now simply copy bytes around.
598
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000599- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
600 278.
601
Brett Cannonc3647ac2005-04-26 03:45:26 +0000602- patch #1109424: int, long, float, complex, and unicode now check for the
603 proper magic slot for type conversions when subclassed. Previously the
604 magic slot was ignored during conversion. Semantics now match the way
605 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000606 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000607 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000608 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +0000610- Descriptors defined in C with a PyGetSetDef structure, where the setter is
611 NULL, now raise an AttributeError when attempting to set or delete the
612 attribute. Previously a TypeError was raised, but this was inconsistent
613 with the equivalent pure-Python implementation.
614
Michael W. Hudson774479c2005-04-18 08:46:17 +0000615- It is now safe to call PyGILState_Release() before
616 PyEval_InitThreads() (note that if there is reason to believe there
617 are multiple threads around you still must call PyEval_InitThreads()
618 before using the Python API; this fix is for extension modules that
619 have no way of knowing if Python is multi-threaded yet).
620
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000621- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
622 disabled caused a crash.
623
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000624- Bug #1165306: instancemethod_new allowed the creation of a method
625 with im_class == im_self == NULL, which caused a crash when called.
626
Tim Petersecc6e6a2005-07-10 22:30:55 +0000627- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000628 fixes the crash seen in bug #1165761
629
Raymond Hettinger96229b12005-03-11 06:49:40 +0000630- Added two new builtins, any() and all().
631
Brett Cannon409d8f22005-03-05 06:47:57 +0000632- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000633 (e.g., ``class C(): pass`` is no longer a syntax error).
634 Patch #1176012 added support to the 'parser' module and 'compiler' package
635 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000636
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000637- Patch #1115086: Support PY_LONGLONG in structmember.
638
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000639- Bug #1155938: new style classes did not check that __init__() was
640 returning None.
641
Tim Petersecc6e6a2005-07-10 22:30:55 +0000642- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000643 ('\') with a specific error message.
644
Martin v. Löwisff232d72005-03-03 09:24:38 +0000645- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
646
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000647- Bug #1124295: the __name__ attribute of file objects was
648 inadvertently made inaccessible in restricted mode.
649
Tim Petersecc6e6a2005-07-10 22:30:55 +0000650- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000651 an ferror() call.
652
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000653- min() and max() now support key= arguments with the same meaning as in
654 list.sort().
655
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000656- The peephole optimizer now performs simple constant folding in expressions:
657 (2+3) --> (5).
658
Raymond Hettingera422c342005-01-11 03:03:27 +0000659- set and frozenset objects can now be marshalled. SF #1098985.
660
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000661- Bug #1077106: Poor argument checking could cause memory corruption
662 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000663
Jeremy Hyltonab630502005-02-04 18:44:06 +0000664- The parser did not complain about future statements in illegal
665 positions. It once again reports a syntax error if a future
666 statement occurs after anything other than a doc string.
667
Neil Schemenauercf52c072005-08-12 17:34:58 +0000668- Change the %s format specifier for str objects so that it returns a
669 unicode instance if the argument is not an instance of basestring and
670 calling __str__ on the argument returns a unicode instance.
671
Tim Petersf4e69282006-02-27 17:15:31 +0000672- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
673 current thread state when the auto-GIL-state machinery knows about
674 it (since the thread state is being deleted, continuing to remember it
675 can't help, but can hurt if another thread happens to get created with
676 the same thread id).

706 for applications that require this specific version (such as IDNA).
707
Neal Norwitzb62c4332006-03-04 18:35:47 +0000708- The timing module is no longer built by default. It was deprecated

866-------
867
Nick Coghlan43832302006-04-23 17:04:07 +0000868- PEP 338: new module runpy defines a run_module function to support

880 in attribute values.
881
Anthony Baxterc51ee692006-04-01 00:57:31 +0000882- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000883 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000884 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000885 module will not be built.
886
Tim Petersc17976e2006-04-01 00:26:53 +0000887- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
888 aren't officially supported here, and trying to use them will probably
889 raise an exception some day. But dicts have been allowed, and "mostly
890 worked", so support for them won't go away without warning.
891
Georg Brandl338ef7d2006-03-31 18:42:16 +0000892- Bug #1445068: getpass.getpass() can now be given an explicit stream
893 argument to specify where to write the prompt.
894
Georg Brandl22ec80b2006-03-31 18:25:44 +0000895- Patch #1462313, bug #1443328: the pickle modules now can handle classes

901 key to be used for signing the uploaded code.
902
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000903- Queue.Queue objects now support .task_done() and .join() methods
904 to make it easier to monitor when daemon threads have completed
905 processing all enqueued tasks. Patch #1455676.
906
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000907- popen2.Popen objects now preserve the command in a .cmd attribute.
908

910
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000911- email 4.0 package now integrated. This is largely the same as the email 3.0
912 package that was included in Python 2.3, except that PEP 8 module names are
913 now used (e.g. mail.message instead of email.Message). The MIME classes
914 have been moved to a subpackage (e.g. email.mime.text instead of
915 email.MIMEText). The old names are still supported for now. Several
916 deprecated Message methods have been removed and lots of bugs have been
917 fixed. More details can be found in the email package documentation.
918
Walter Dörwald40108c92006-03-27 08:15:44 +0000919- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
920 (a subclass of tuple) that provides incremental decoders and encoders
921 (a way to use stateful codecs without the stream API). Python functions
922 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
923 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
924 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000925
Walter Dörwald067db482006-03-15 22:17:27 +0000926- Patch #1359365: Calling next() on a closed StringIO.String object raises
927 a ValueError instead of a StopIteration now (like file and cString.String do).
928 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
929 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000930

935
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000936- The function get_count() has been added to the gc module, and gc.collect()
937 grew an optional 'generation' argument.
938
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000939- A library msilib to generate Windows Installer files, and a distutils
940 command bdist_msi have been added.
941
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000942- PEP 343: new module contextlib.py defines decorator @contextmanager
943 and helpful context managers nested() and closing().
944

999 LoadError as documented, instead of IOError. For compatibility,
1000 LoadError subclasses IOError.
1001
Brett Cannon3cbd0382005-12-16 22:49:23 +00001002- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001003 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1004 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1005 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1006 Ronald L. Rivest offered this advice for Python:
1007
1008 "The consensus of researchers in this area (at least as
1009 expressed at the NIST Hash Function Workshop 10/31/05),
1010 is that SHA-256 is a good choice for the time being, but
1011 that research should continue, and other alternatives may
1012 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001013
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001014- Added a subset of Fredrik Lundh's ElementTree package. Available

1122 class at all.
1123
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001124- distutils.commands.upload was added to support uploading distribution

1168
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001169- Patch #1049151: xdrlib now unpacks booleans as True or False.
1170
Raymond Hettingerbab41432005-02-05 01:31:19 +00001171- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1172
Guido van Rossumd0641422005-02-03 15:01:24 +00001173- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1174 disables recursive traversal through instance attributes, which can
1175 be exploited in various ways.
1176
Tim Peterse3547fd2005-12-16 23:13:57 +00001177- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001178 flags on the HTTP listening socket.
1179
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001180- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1181 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1182
Tim Peterse3547fd2005-12-16 23:13:57 +00001183- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001184 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1185

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001188- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1189
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001190- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1191
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001192- Enhancements to the csv module:
1193
1194 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001195 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001196 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001197 + Dialect parameter parsing has been re-implemented to improve error
1198 reporting.
1199 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1200 dictates.
1201 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001202 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001203 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001204 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1205 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001206 + reader now allows \r characters to be quoted (previously it only allowed
1207 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001208 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001209 + Dialect classes passed to the module are no longer instantiated by
1210 the module before being parsed (the former validation scheme required
1211 this, but the mechanism was unreliable).
1212 + The dialect registry now contains instances of the internal
1213 C-coded dialect type, rather than references to python objects.
1214 + the internal c-coded dialect type is now immutable.
1215 + register_dialect now accepts the same keyword dialect specifications
1216 as the reader and writer, allowing the user to register dialects
1217 without first creating a dialect class.
1218 + a configurable limit to the size of parsed fields has been added -
1219 previously, an unmatched quote character could result in the entire
1220 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001221 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001222 the parser field size limit (returning the former limit). The initial
1223 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001224 + A line_num attribute has been added to the reader object, which tracks
1225 the number of lines read from the source iterator. This is not
1226 the same as the number of records returned, as records can span
1227 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001228 + reader and writer objects were not being registered with the cyclic-GC.
1229 This has been fixed.
1230
Brett Cannone6539c42005-01-08 02:43:53 +00001231- _DummyThread objects in the threading module now delete self.__block that is
1232 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1233 lock primitives tend to be limited in number and thus should not be wasted on
1234 a _DummyThread object. Fixes bug #1089632.
1235
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001236- The imghdr module now detects Exif files.
1237
Raymond Hettinger6065d322004-12-20 23:51:53 +00001238- StringIO.truncate() now correctly adjusts the size attribute.
1239 (Bug #951915).
1240
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001241- locale.py now uses an updated locale alias table (built using
1242 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1243 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001244 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001245
Raymond Hettinger3557f422004-12-07 12:02:02 +00001246- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1247
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001248- the pickle module no longer accepts the deprecated None option in the
1249 args tuple returned by __reduce__().
1250
Brett Cannon84667c02004-12-07 03:25:18 +00001251- optparse now optionally imports gettext. This allows its use in setup.py.
1252
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001253- the pickle module no longer uses the deprecated bin parameter.
1254
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001255- the shelve module no longer uses the deprecated binary parameter.
1256
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001257- the pstats module no longer uses the deprecated ignore() method.
1258
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001259- the filecmp module no longer uses the deprecated use_statcache argument.
1260
Raymond Hettinger664347b2004-12-04 21:21:53 +00001261- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1262 extended or overridden by subclasses. Formerly, the subclassed method would
1263 be ignored by the rest of the module. (Bug #1078905).
1264
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001265- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001266 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001267
Walter Dörwald36733692004-12-22 12:50:50 +00001268- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1269 once when a size argument is given. This prevents a buffer overflow in the
1270 tokenizer with very long source lines.
1271
Barry Warsaw538561e2006-01-01 21:48:54 +00001272- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1273 immediately after creating the object, without any intervening
1274 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001275
Skip Montanaro05885812005-01-16 20:48:27 +00001276- The reconvert.quote function can now emit triple-quoted strings. The
1277 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001278
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001279- ``UserString.MutableString`` now supports negative indices in
1280 ``__setitem__`` and ``__delitem__``
1281
Greg Ward40407942005-03-05 02:53:17 +00001282- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1283 correctly.
1284
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001285- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1286 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1287 character even if the user has passed a size parameter to get a proper
1288 line ending. Remove the special handling of a "\r\n" that has been split
1289 between two lines.
1290
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001291- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1292 about illegal code points. The codec now supports PEP 293 style error
1293 handlers.
1294
Walter Dörwald78a78b02005-09-01 12:04:29 +00001295- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001296 from the input stream, so that the output is a byte string in the correct
1297 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001298
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001299- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1300 considering it exactly like a '*'.
1301
Walter Dörwald007f8df2005-10-09 19:42:27 +00001302- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1303 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001304
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001305- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1306
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001307- Patch #1413711: Certain patterns of differences were making difflib
1308 touch the recursion limit.
1309
Walter Dörwald58917a62006-03-31 15:26:22 +00001310- Bug #947906: An object oriented interface has been added to the calendar
1311 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001312 called as a script (e.g. via ``python -mcalendar``). Localized month and
1313 weekday names can be ouput (even if an exotic encoding is used) using
1314 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001315
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001316Build
1317-----
1318
Neal Norwitz602d3392006-03-31 08:21:40 +00001319- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1320 by using -mieee gcc option.
1321

1323
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001324- Build support for Win64-AMD64 was added.
1325
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001326- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1327
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001328- Patch #881820: look for openpty and forkpty also in libbsd.
1329
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001330- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1331 The zlib module is now builtin on Windows.
1332
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001333- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1334
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001335- Bug #1189330: configure did not correctly determine the necessary
1336 value of LINKCC if python was built with GCC 4.0.
1337
Trent Mick8321b422005-07-26 02:29:21 +00001338- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1339 vulnerability in zlib 1.2.1 and 1.2.2.
1340
Brett Cannon08cd5982005-04-24 22:26:38 +00001341- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1342 flags that change binary compatibility. Changes were also made to
1343 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001344 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001345
Bob Ippolitoed233462005-03-29 13:47:59 +00001346- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1347 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1348 no longer exists). This configure patch makes things right.
1349
Martin v. Löwise2713be2005-03-08 15:03:08 +00001350- Bug #1158607: Build with --disable-unicode again.
1351
Brett Cannon46d96232005-02-16 00:07:19 +00001352- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1353 defined. Discovered as a result of not being able to build on OS X.
1354
Brett Cannon516592f2004-12-07 00:42:59 +00001355- setup.py now uses the directories specified in LDFLAGS using the -L option
1356 and in CPPFLAGS using the -I option for adding library and include
1357 directories, respectively, for compiling extension modules against. This has
1358 led to the core being compiled using the values in CPPFLAGS. It also removes
1359 the need for the special-casing of both DarwinPorts and Fink for darwin since
1360 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1361 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1362 Fink, ``-I/opt/local/include`` for DarwinPorts).
1363
Brett Cannon43802422005-02-10 20:48:03 +00001364- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1365 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1366 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1367 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001369C API
1370-----
1371
Tim Petersc9d78aa2006-03-26 23:27:58 +00001372- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1373 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1374 is obtained via the ``PyObject_`` family, it must be released via the
1375 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1376 always been officially true, but when Python's small-object allocator was
1377 introduced, an attempt was made to cater to a few extension modules
1378 discovered at the time that obtained memory via ``PyObject_New`` but
1379 released it via ``PyMem_DEL``. It's years later, and if such code still
1380 exists it will fail now (probably with segfaults, but calling wrong
1381 low-level memory management functions can yield many symptoms).
1382
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001383- Added a C API for set and frozenset objects.
1384
Raymond Hettinger66517482004-12-03 11:45:13 +00001385- Removed PyRange_New().
1386
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001387- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1388 mapping argument now. This string is used as a mapping table. Byte values
1389 greater than the length of the string and 0xFFFE are treated as undefined
1390 mappings.
