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 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
Nick Coghlanc649ec52006-05-29 12:43:05 +000078- Patch #1478788 (modified version): The functional extension module has
79 been renamed to _functools and a functools Python wrapper module added.
80 This provides a home for additional function related utilities that are
81 not specifically about functional programming. See PEP 309.
82
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000083- Patch #1493701: performance enhancements for struct module.
84
Georg Brandl378d5922006-05-17 14:26:50 +000085- Patch #1490224: time.altzone is now set correctly on Cygwin.
86
Georg Brandl8d3342b2006-05-16 07:38:27 +000087- Patch #1435422: zlib's compress and decompress objects now have a
88 copy() method.
89
Neal Norwitz7a5fc282006-05-15 06:48:14 +000090- On Win32, os.listdir now supports arbitrarily-long Unicode path names
91 (up to the system limit of 32K characters).
92
93- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
94 As a result, these functions now raise WindowsError instead of OSError.
95
Tim Peters7a822da2006-05-25 21:50:17 +000096- ``time.clock()`` on Win64 should use the high-performance Windows
97 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
98 Windows platforms).
99
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000100- Calling Tk_Init twice is refused if the first call failed as that
101 may deadlock.
102
Nick Coghlanc649ec52006-05-29 12:43:05 +0000103
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000104Library
105-------
106
Martin v. Löwis3f767792006-06-04 19:36:28 +0000107- Patch #1359618: Speed up charmap encoder by using a trie structure
108 for lookup.
109
Tim Petersd609b1a2006-06-02 23:22:51 +0000110- The functions in the ``pprint`` module now sort dictionaries by key
111 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
112 if and only if its display required more than one line, although that
113 wasn't documented. The new behavior increases predictability; e.g.,
114 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
115
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000116- Patch #1497027: try HTTP digest auth before basic auth in urllib2
117 (thanks for J. J. Lee).
118
Georg Brandl2b330372006-05-28 20:23:12 +0000119- Patch #1496206: improve urllib2 handling of passwords with respect to
120 default HTTP and HTTPS ports.
121
George Yoshidaf3c65de2006-05-28 16:39:09 +0000122- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
123
Bob Ippolito7298f272006-05-23 18:43:47 +0000124- Patch #1281707: speed up gzip.readline.
125
Georg Brandlb89316f2006-05-17 15:51:16 +0000126- Patch #1180296: Two new functions were added to the locale module:
127 format_string() to get the effect of "format % items" but locale-aware,
128 and currency() to format a monetary number with currency sign.
129
Georg Brandle3a25832006-05-17 14:56:04 +0000130- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
131 and several features added, such as speed and geometry control.
132
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000133- Patch #1488881: add support for external file objects in bz2 compressed
134 tarfiles.
135
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000136- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
137 stdout arguments, making it possible to redirect input and output
138 for remote debugging.
139
140- Patch #1484695: Update the tarfile module to version 0.8. This fixes
141 a couple of issues, notably handling of long file names using the
142 GNU LONGNAME extension.
143
144- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
145 new flag when ``name`` is already the name of an option flag.
146
147- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
148 package.
149
150- Patch #1472854: make the rlcompleter.Completer class usable on non-
151 UNIX platforms.
152
153- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000180What's New in Python 2.5 alpha 2?
181=================================
182
183*Release date: 27-APR-2006*
184
185Core and builtins
186-----------------
187
Thomas Heller1b046642006-04-18 18:51:06 +0000188- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
189 by converting these apis from macros into exported functions again:
190
191 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
192 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
193 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
194 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
195 PyRun_String Py_CompileString
196
Martin v. Löwis45294a92006-04-18 06:24:08 +0000197- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
198
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000199- All uses of PyStructSequence_InitType have been changed to initialize
200 the type objects only once, even if the interpreter is initialized
201 multiple times.
202
Neal Norwitz61546162006-04-14 05:20:28 +0000203- Bug #1454485, array.array('u') could crash the interpreter. This was
204 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
205 to unicode when it didn't make sense. 'u#' now requires a unicode string.
206
207- Py_UNICODE is unsigned. It was always documented as unsigned, but
208 due to a bug had a signed value in previous versions.
209
Tim Peters3a5e8b12006-04-11 01:44:07 +0000210- Patch #837242: ``id()`` of any Python object always gives a positive
211 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
212 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000213 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000214 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000215
Tim Peters3a5e8b12006-04-11 01:44:07 +0000216 def __hash__(self):
217 return id(self) # WRONG
218
219 because a hash result must be a (short) Python int but it was always
220 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000221 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000222 was always usable as a hash value before this patch. That's no longer
223 necessarily so.
224
225- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000226 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000227 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000228 #1454844)
229
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000230- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
231 involving generators that have paused outside of any ``try`` or ``with``
232 blocks. (In 2.5a1, a paused generator that was part of a reference
233 cycle could not be garbage collected, regardless of whether it was
234 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000236Extension Modules
237-----------------
238
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000239- Patch #1191065: Fix preprocessor problems on systems where recvfrom
240 is a macro.
241
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000242- Bug #1467952: os.listdir() now correctly raises an error if readdir()
243 fails with an error condition.
244
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000245- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
246
247- Bug #1117761: bsddb.*open() no longer raises an exception when using
248 the cachesize parameter.
249
250- Bug #1149413: bsddb.*open() no longer raises an exception when using
251 a temporary db (file=None) with the 'n' flag to truncate on open.
252
253- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
254 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000255
Armin Rigoa9017c32006-04-19 11:50:27 +0000256- Patch #1062014: AF_UNIX sockets under Linux have a special
257 abstract namespace that is now fully supported.
258

260-------
261
Tim Peters711bf302006-04-25 03:31:36 +0000262- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
263 a doctest to be skipped (the code is not run, and the expected output
264 or exception is ignored).
265
Nick Coghlanda2268f2006-04-24 04:37:15 +0000266- Fixed contextlib.nested to cope with exceptions being raised and
267 caught inside exit handlers.
268
Greg Wardab05edc2006-04-23 03:47:58 +0000269- Updated optparse module to Optik 1.5.1 (allow numeric constants in
270 hex, octal, or binary; add ``append_const`` action; keep going if
271 gettext cannot be imported; added ``OptionParser.destroy()`` method;
272 added ``epilog`` for better help generation).
273
Tim Peters21fbd572006-04-21 21:18:10 +0000274- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
275 called from a thread spawned as a side effect of importing a module.
276
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000277- The pydoc module now supports documenting packages contained in
278 .zip or .egg files.
279
280- The pkgutil module now has several new utility functions, such
281 as ``walk_packages()`` to support working with packages that are either
282 in the filesystem or zip files.
283
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000284- The mailbox module can now modify and delete messages from
285 mailboxes, in addition to simply reading them. Thanks to Gregory
286 K. Johnson for writing the code, and to the 2005 Google Summer of
287 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000288
Tim Petersc7605f22006-04-17 21:12:33 +0000289- The ``__del__`` method of class ``local`` in module ``_threading_local``
290 returned before accomplishing any of its intended cleanup.
291
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000292- Patch #790710: Add breakpoint command lists in pdb.
293
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000294- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000296- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
297
Anthony Baxtere29002c2006-04-12 12:07:31 +0000298- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
299 Windows. Bug #1469163.
300
Phillip J. Eby47032112006-04-11 01:07:43 +0000301- The warnings, linecache, inspect, traceback, site, and doctest modules
302 were updated to work correctly with modules imported from zipfiles or
303 via other PEP 302 __loader__ objects.
304
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000305- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000318- The Makefile now has a reindent target, which runs reindent.py on
319 the library.
320

326 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000327 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000328 CXX from --with-cxx-main, see description in README.
329
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000330- Patch #1429775: Link extension modules with the shared libpython.
331
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000332- Fixed a libffi build problem on MIPS systems.
333
Tim Peters8931ff12006-05-13 23:28:20 +0000334- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
335 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
336 and "%zu" for unsigned integers of type ``size_t``.
337
Anthony Baxter51bcb682006-04-05 14:51:42 +0000338Tests
339-----
340
Nick Coghlanda2268f2006-04-24 04:37:15 +0000341- test_contextlib now checks contextlib.nested can cope with exceptions
342 being raised and caught inside exit handlers.
343
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000344- test_cmd_line now checks operation of the -m and -c command switches
345
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000346- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
347 it separately and by hand. It also wasn't cleaning up its changes to
348 the current Decimal context.
349
Thomas Woutersabd08882006-04-26 15:53:30 +0000350- regrtest.py now has a -M option to run tests that test the new limits of
351 containers, on 64-bit architectures. Running these tests is only sensible
352 on 64-bit machines with more than two gigabytes of memory. The argument
353 passed is the maximum amount of memory for the tests to use.

357
358- Added the Python benchmark suite pybench to the Tools/ directory;
359 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000361Documentation
362-------------
363
Tim Petersb06d28c2006-05-12 01:57:59 +0000364- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
365
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000366- PEP 343: Added Context Types section to the library reference
367 and attempted to bring other PEP 343 related documentation into
368 line with the implementation and/or python-dev discussions.
369
Tim Peters8dc73d22006-04-24 02:03:16 +0000370- Bug #1337990: clarified that ``doctest`` does not support examples
371 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000374What's New in Python 2.5 alpha 1?
375=================================
376
Anthony Baxterebed3f62006-04-03 15:03:44 +0000377*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000378
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000379Core and builtins
380-----------------
381
Nick Coghlan43832302006-04-23 17:04:07 +0000382- PEP 338: -m command line switch now delegates to runpy.run_module
383 allowing it to support modules in packages and zipfiles
384
Martin v. Löwisc661b882006-04-20 04:54:23 +0000385- On Windows, .DLL is not an accepted file name extension for
386 extension modules anymore; extensions are only found if they
387 end in .PYD.
388
Martin v. Löwisea62d252006-04-03 10:56:49 +0000389- Bug #1421664: sys.stderr.encoding is now set to the same value as
390 sys.stdout.encoding.
391
Neal Norwitz92e212f2006-04-03 04:48:37 +0000392- __import__ accepts keyword arguments.
393
Georg Brandlccadf842006-03-31 18:54:53 +0000394- Patch #1460496: round() now accepts keyword arguments.
395
Anthony Baxter262c00a2006-03-30 10:53:17 +0000396- Fixed bug #1459029 - unicode reprs were double-escaped.
397
Hye-Shik Changd478f342006-03-23 12:32:36 +0000398- Patch #1396919: The system scope threads are reenabled on FreeBSD
399 5.4 and later versions.
400
Neal Norwitze98ccf62006-03-23 05:39:47 +0000401- Bug #1115379: Compiling a Unicode string with an encoding declaration
402 now gives a SyntaxError.
403
Georg Brandlabd1ff82006-03-18 07:59:59 +0000404- Previously, Python code had no easy way to access the contents of a
405 cell object. Now, a ``cell_contents`` attribute has been added
406 (closes patch #1170323).
407
Tim Peterscf79aac2006-03-16 01:14:46 +0000408- Patch #1123430: Python's small-object allocator now returns an arena to
409 the system ``free()`` when all memory within an arena becomes unused
410 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
411 freed. Some applications will see a drop in virtual memory size now,
412 especially long-running applications that, from time to time, temporarily
413 use a large number of small objects. Note that when Python returns an
414 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000415 platform C library will in turn return that memory to the operating system.
416 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000417 appears to be effective at least on Microsoft C and gcc-based systems.
418 Thanks to Evan Jones for hard work and patience.
419
Georg Brandl533ff6f2006-03-08 18:09:27 +0000420- Patch #1434038: property() now uses the getter's docstring if there is
421 no "doc" argument given. This makes it possible to legitimately use
422 property() as a decorator to produce a read-only property.
423
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000424- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
425 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
426 of requiring an int or long in slicing and a few other contexts, enabling
427 other objects (e.g. Numeric Python's integers) to be used as slice indices.
428
Neal Norwitz995acdf2006-03-07 05:01:00 +0000429- Fixed various bugs reported by Coverity's Prevent tool.
430
Brett Cannonbf364092006-03-01 04:25:17 +0000431- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
432 new exception base class, BaseException, which has a new message attribute.
433 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
434 Raising a string exception now raises a DeprecationWarning.
435
Thomas Woutersfb609f42006-02-28 16:37:25 +0000436- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
437 explicitly relative, using 'from .module import name' to mean 'from the same
438 package as this module is in. Imports without dots still default to the
439 old relative-then-absolute, unless 'from __future__ import
440 absolute_import' is used.
441
Brett Cannona7446e32006-02-27 23:39:10 +0000442- Properly check if 'warnings' raises an exception (usually when a filter set
443 to "error" is triggered) when raising a warning for raising string
444 exceptions.
445
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000446- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000447 The name was removed from Include/code.h.
448
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000449- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000450
Guido van Rossum1968ad32006-02-25 22:38:04 +0000451- Patch 1433928:
452 - The copy module now "copies" function objects (as atomic objects).
453 - dict.__getitem__ now looks for a __missing__ hook before raising
454 KeyError.
455
Tim Peters84ef21c2006-02-28 20:39:06 +0000456- PEP 343: with statement implemented. Needs ``from __future__ import
457 with_statement``. Use of 'with' as a variable will generate a warning.
458 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000459 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000460 The following objects have __context__ methods:
461 - The built-in file type.
462 - The thread.LockType type.
463 - The following types defined by the threading module:
464 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
465 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000466
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000467- Fix the encodings package codec search function to only search
468 inside its own package. Fixes problem reported in patch #1433198.
469
470 Note: Codec packages should implement and register their own
471 codec search function. PEP 100 has the details.
472
Tim Peters9ea89d22006-06-04 03:26:02 +0000473- PEP 353: Using ``Py_ssize_t`` as the index type.
474
475- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
476 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
477 now allow Python to make use of memory blocks exceeding 2**32 bytes for
478 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
479 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000480
Neal Norwitzfc76d632006-01-10 06:03:13 +0000481- Patch #1400181, fix unicode string formatting to not use the locale.
482 This is how string objects work. u'%f' could use , instead of .
483 for the decimal point. Now both strings and unicode always use periods.
484
Neal Norwitz671b9e32006-01-09 07:07:12 +0000485- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
486 configure would break checking curses.h.
487
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000488- Bug #959576: The pwd module is now builtin. This allows Python to be
489 built on UNIX platforms without $HOME set.
490
Neal Norwitzc10978f2005-12-19 06:07:16 +0000491- Bug #1072182, fix some potential problems if characters are signed.
492
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000493- Bug #889500, fix line number on SyntaxWarning for global declarations.
494
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000495- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
496
Neal Norwitze7214a12005-12-18 05:03:17 +0000497- Support for converting hex strings to floats no longer works.
498 This was not portable. float('0x3') now raises a ValueError.
499
Barry Warsaw2a38a862005-12-18 01:27:35 +0000500- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000501 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000502 is now displayed in interactive prompt banner.
503
Georg Brandlfa166682005-12-17 21:45:17 +0000504- Implementation of PEP 341 - Unification of try/except and try/finally.
505 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000506 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000507
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000508- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
509 now encodes backslash correctly.
510
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000511- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
512
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000513- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000514 and long longs.
515
Neal Norwitz67715f02005-11-09 06:59:35 +0000516- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000517 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000518 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000519
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000520- Replaced most Unicode charmap codecs with new ones using the
521 new Unicode translate string feature in the builtin charmap
522 codec; the codecs were created from the mapping tables available
523 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
524 encodings now include a mapping for the Apple logo)
525
Tim Peterse3547fd2005-12-16 23:13:57 +0000526- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000527
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000528- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000529
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000530- A new AST parser implementation was completed. The abstract
531 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000532 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000533
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000534- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000535 The following code now raises a SyntaxError: foo(a = i for i in range(10))
536
Neal Norwitz708e51a2005-10-03 04:48:15 +0000537- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
538
Neal Norwitz11bd1192005-10-03 00:54:56 +0000539- SF Bug #887946: fix segfault when redirecting stdin from a directory.
540 Provide a warning when a directory is passed on the command line.
541
Neal Norwitz40d37812005-10-02 01:48:49 +0000542- Fix segfault with invalid coding.
543
544- SF bug #772896: unknown encoding results in MemoryError.
545
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000546- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000547 supported a __len__() method which evaluated to False when the iterator
548 was empty.
549
Guido van Rossum630db602005-09-20 18:49:54 +0000550- On 64-bit platforms, when __len__() returns a value that cannot be
551 represented as a C int, raise OverflowError.
552
Skip Montanarof8948ca2005-09-19 03:54:46 +0000553- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000554 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000555
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000556- SF bug #893549: parsing keyword arguments was broken with a few format
557 codes.
558
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000559- Changes donated by Elemental Security to make it work on AIX 5.3
560 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
561 bug #105470: test_pwd fails on 64bit system (Opteron).
562
Guido van Rossum539c6622005-09-14 17:49:54 +0000563- Changes donated by Elemental Security to make it work on HP-UX 11 on
564 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
565
Georg Brandl4550b8d2005-08-26 06:43:52 +0000566- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000567 (fixes bug #1119418).
568
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000569- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
570
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000571- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
572 exceptions that cause a function to exit.
573
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000574- The implementation of set() and frozenset() was revised to use its
575 own internal data structure. Memory consumption is reduced by 1/3
576 and there are modest speed-ups as well. The API is unchanged.
577
Tim Petersde7990b2005-07-17 23:45:23 +0000578- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
579
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000580- SF bug #1229429: PyObject_CallMethod failed to decrement some
581 reference counts in some error exit cases.
582
Tim Petersecc6e6a2005-07-10 22:30:55 +0000583- SF bug #1185883: Python's small-object memory allocator took over
584 a block managed by the platform C library whenever a realloc specified
585 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000586 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000587 portable way to copy data from the C-managed block into Python's
588 small-object space without risking a memory fault. Python's small-object
589 realloc now leaves such blocks under the control of the platform C
590 realloc.
591
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000592- SF bug #1232517: An overflow error was not detected properly when
593 attempting to convert a large float to an int in os.utime().
594
Raymond Hettinger3296e692005-06-29 23:29:56 +0000595- SF bug #1224347: hex longs now print with lowercase letters just
596 like their int counterparts.
597
Michael W. Hudson188d4362005-06-20 16:52:57 +0000598- SF bug #1163563: the original fix for bug #1010677 ("thread Module
599 Breaks PyGILState_Ensure()") broke badly in the case of multiple
600 interpreter states; back out that fix and do a better job (see
601 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
602 for a longer write-up of the problem).
603
Michael W. Hudsondf888462005-06-03 14:41:55 +0000604- SF patch #1180995: marshal now uses a binary format by default when
605 serializing floats.
606
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000607- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
608 the routines that promise to produce IEEE 754 binary representations
609 of floats now simply copy bytes around.
610
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000611- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP

Brett Cannonc3647ac2005-04-26 03:45:26 +0000614- patch #1109424: int, long, float, complex, and unicode now check for the
615 proper magic slot for type conversions when subclassed. Previously the
616 magic slot was ignored during conversion. Semantics now match the way
617 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000618 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000619 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000620 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000621
Barry Warsawc8d907c2005-04-19 23:43:40 +0000622- Descriptors defined in C with a PyGetSetDef structure, where the setter is
623 NULL, now raise an AttributeError when attempting to set or delete the
624 attribute. Previously a TypeError was raised, but this was inconsistent
625 with the equivalent pure-Python implementation.
626
Michael W. Hudson774479c2005-04-18 08:46:17 +0000627- It is now safe to call PyGILState_Release() before
628 PyEval_InitThreads() (note that if there is reason to believe there
629 are multiple threads around you still must call PyEval_InitThreads()
630 before using the Python API; this fix is for extension modules that
631 have no way of knowing if Python is multi-threaded yet).
632
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000633- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
634 disabled caused a crash.
635
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000636- Bug #1165306: instancemethod_new allowed the creation of a method
637 with im_class == im_self == NULL, which caused a crash when called.
638
Tim Petersecc6e6a2005-07-10 22:30:55 +0000639- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000640 fixes the crash seen in bug #1165761
641
Raymond Hettinger96229b12005-03-11 06:49:40 +0000642- Added two new builtins, any() and all().
643
Brett Cannon409d8f22005-03-05 06:47:57 +0000644- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000645 (e.g., ``class C(): pass`` is no longer a syntax error).
646 Patch #1176012 added support to the 'parser' module and 'compiler' package
647 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000648
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000649- Patch #1115086: Support PY_LONGLONG in structmember.
650
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000651- Bug #1155938: new style classes did not check that __init__() was
652 returning None.
653
Tim Petersecc6e6a2005-07-10 22:30:55 +0000654- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000655 ('\') with a specific error message.
656
Martin v. Löwisff232d72005-03-03 09:24:38 +0000657- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
658
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000659- Bug #1124295: the __name__ attribute of file objects was
660 inadvertently made inaccessible in restricted mode.
661
Tim Petersecc6e6a2005-07-10 22:30:55 +0000662- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000663 an ferror() call.
664
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000665- min() and max() now support key= arguments with the same meaning as in
666 list.sort().
667
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000668- The peephole optimizer now performs simple constant folding in expressions:
669 (2+3) --> (5).
670
Raymond Hettingera422c342005-01-11 03:03:27 +0000671- set and frozenset objects can now be marshalled. SF #1098985.
672
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000673- Bug #1077106: Poor argument checking could cause memory corruption
674 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000675
Jeremy Hyltonab630502005-02-04 18:44:06 +0000676- The parser did not complain about future statements in illegal
677 positions. It once again reports a syntax error if a future
678 statement occurs after anything other than a doc string.
679
Neil Schemenauercf52c072005-08-12 17:34:58 +0000680- Change the %s format specifier for str objects so that it returns a
681 unicode instance if the argument is not an instance of basestring and
682 calling __str__ on the argument returns a unicode instance.
683
Tim Petersf4e69282006-02-27 17:15:31 +0000684- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
685 current thread state when the auto-GIL-state machinery knows about
686 it (since the thread state is being deleted, continuing to remember it
687 can't help, but can hurt if another thread happens to get created with
688 the same thread id).

718 for applications that require this specific version (such as IDNA).
719
Neal Norwitzb62c4332006-03-04 18:35:47 +0000720- The timing module is no longer built by default. It was deprecated

892 in attribute values.
893
Anthony Baxterc51ee692006-04-01 00:57:31 +0000894- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000895 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000896 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000897 module will not be built.
898
Tim Petersc17976e2006-04-01 00:26:53 +0000899- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
900 aren't officially supported here, and trying to use them will probably
901 raise an exception some day. But dicts have been allowed, and "mostly
902 worked", so support for them won't go away without warning.
903
Georg Brandl338ef7d2006-03-31 18:42:16 +0000904- Bug #1445068: getpass.getpass() can now be given an explicit stream
905 argument to specify where to write the prompt.
906
Georg Brandl22ec80b2006-03-31 18:25:44 +0000907- Patch #1462313, bug #1443328: the pickle modules now can handle classes

913 key to be used for signing the uploaded code.
914
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000915- Queue.Queue objects now support .task_done() and .join() methods
916 to make it easier to monitor when daemon threads have completed
917 processing all enqueued tasks. Patch #1455676.
918
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000919- popen2.Popen objects now preserve the command in a .cmd attribute.
920
Thomas Hellerc61c0492006-03-22 10:09:27 +0000921- Added the ctypes ffi package.
922
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000923- email 4.0 package now integrated. This is largely the same as the email 3.0
924 package that was included in Python 2.3, except that PEP 8 module names are
925 now used (e.g. mail.message instead of email.Message). The MIME classes
926 have been moved to a subpackage (e.g. email.mime.text instead of
927 email.MIMEText). The old names are still supported for now. Several
928 deprecated Message methods have been removed and lots of bugs have been
929 fixed. More details can be found in the email package documentation.
930
Walter Dörwald40108c92006-03-27 08:15:44 +0000931- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
932 (a subclass of tuple) that provides incremental decoders and encoders
933 (a way to use stateful codecs without the stream API). Python functions
934 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
935 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
936 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000937
Walter Dörwald067db482006-03-15 22:17:27 +0000938- Patch #1359365: Calling next() on a closed StringIO.String object raises
939 a ValueError instead of a StopIteration now (like file and cString.String do).
940 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
941 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000942
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000943- A regrtest option -w was added to re-run failed tests in verbose mode.

946 interpreter to exit.
947
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000948- The function get_count() has been added to the gc module, and gc.collect()
949 grew an optional 'generation' argument.
950
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000951- A library msilib to generate Windows Installer files, and a distutils
952 command bdist_msi have been added.
953

1011 LoadError as documented, instead of IOError. For compatibility,
1012 LoadError subclasses IOError.
1013

Tim Peterse3547fd2005-12-16 23:13:57 +00001015 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1016 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1017 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1018 Ronald L. Rivest offered this advice for Python:
1019
1020 "The consensus of researchers in this area (at least as
1021 expressed at the NIST Hash Function Workshop 10/31/05),
1022 is that SHA-256 is a good choice for the time being, but
1023 that research should continue, and other alternatives may
1024 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001025
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001026- Added a subset of Fredrik Lundh's ElementTree package. Available

1097 parameter, but uses the usual "kwargs=None".
1098

1134 class at all.
1135
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001136- distutils.commands.upload was added to support uploading distribution

1180
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001181- Patch #1049151: xdrlib now unpacks booleans as True or False.
1182
Raymond Hettingerbab41432005-02-05 01:31:19 +00001183- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1184
Guido van Rossumd0641422005-02-03 15:01:24 +00001185- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1186 disables recursive traversal through instance attributes, which can
1187 be exploited in various ways.
1188
Tim Peterse3547fd2005-12-16 23:13:57 +00001189- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001190 flags on the HTTP listening socket.
1191
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001192- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1193 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1194
Tim Peterse3547fd2005-12-16 23:13:57 +00001195- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001196 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1197

1199
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001200- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1201
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001202- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1203
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001204- Enhancements to the csv module:
1205
1206 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001207 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001208 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001209 + Dialect parameter parsing has been re-implemented to improve error
1210 reporting.
1211 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1212 dictates.
1213 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001214 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001215 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001216 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1217 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001218 + reader now allows \r characters to be quoted (previously it only allowed
1219 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001220 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001221 + Dialect classes passed to the module are no longer instantiated by
1222 the module before being parsed (the former validation scheme required
1223 this, but the mechanism was unreliable).
1224 + The dialect registry now contains instances of the internal
1225 C-coded dialect type, rather than references to python objects.
1226 + the internal c-coded dialect type is now immutable.
1227 + register_dialect now accepts the same keyword dialect specifications
1228 as the reader and writer, allowing the user to register dialects
1229 without first creating a dialect class.
1230 + a configurable limit to the size of parsed fields has been added -
1231 previously, an unmatched quote character could result in the entire
1232 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001233 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001234 the parser field size limit (returning the former limit). The initial
1235 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001236 + A line_num attribute has been added to the reader object, which tracks
1237 the number of lines read from the source iterator. This is not
1238 the same as the number of records returned, as records can span
1239 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001240 + reader and writer objects were not being registered with the cyclic-GC.
1241 This has been fixed.
1242
Brett Cannone6539c42005-01-08 02:43:53 +00001243- _DummyThread objects in the threading module now delete self.__block that is
1244 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1245 lock primitives tend to be limited in number and thus should not be wasted on
1246 a _DummyThread object. Fixes bug #1089632.
1247
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001248- The imghdr module now detects Exif files.
1249
Raymond Hettinger6065d322004-12-20 23:51:53 +00001250- StringIO.truncate() now correctly adjusts the size attribute.
1251 (Bug #951915).
1252
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001253- locale.py now uses an updated locale alias table (built using
1254 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1255 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001256 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001257
Raymond Hettinger3557f422004-12-07 12:02:02 +00001258- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1259
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001260- the pickle module no longer accepts the deprecated None option in the
1261 args tuple returned by __reduce__().
1262
Brett Cannon84667c02004-12-07 03:25:18 +00001263- optparse now optionally imports gettext. This allows its use in setup.py.
1264
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001265- the pickle module no longer uses the deprecated bin parameter.
1266
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001267- the shelve module no longer uses the deprecated binary parameter.
1268
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001269- the pstats module no longer uses the deprecated ignore() method.
1270
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001271- the filecmp module no longer uses the deprecated use_statcache argument.
1272
Raymond Hettinger664347b2004-12-04 21:21:53 +00001273- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1274 extended or overridden by subclasses. Formerly, the subclassed method would
1275 be ignored by the rest of the module. (Bug #1078905).
1276
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001277- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001278 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001279
Walter Dörwald36733692004-12-22 12:50:50 +00001280- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1281 once when a size argument is given. This prevents a buffer overflow in the
1282 tokenizer with very long source lines.
1283
Barry Warsaw538561e2006-01-01 21:48:54 +00001284- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1285 immediately after creating the object, without any intervening
1286 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001287
Skip Montanaro05885812005-01-16 20:48:27 +00001288- The reconvert.quote function can now emit triple-quoted strings. The
1289 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001290
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001291- ``UserString.MutableString`` now supports negative indices in
1292 ``__setitem__`` and ``__delitem__``
1293
Greg Ward40407942005-03-05 02:53:17 +00001294- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1295 correctly.
1296
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001297- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1298 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1299 character even if the user has passed a size parameter to get a proper
1300 line ending. Remove the special handling of a "\r\n" that has been split
1301 between two lines.
1302
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001303- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1304 about illegal code points. The codec now supports PEP 293 style error
1305 handlers.
1306
Walter Dörwald78a78b02005-09-01 12:04:29 +00001307- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001308 from the input stream, so that the output is a byte string in the correct
1309 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001310
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001311- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1312 considering it exactly like a '*'.
1313
Walter Dörwald007f8df2005-10-09 19:42:27 +00001314- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1315 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001316
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001317- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1318
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001319- Patch #1413711: Certain patterns of differences were making difflib
1320 touch the recursion limit.
1321
Walter Dörwald58917a62006-03-31 15:26:22 +00001322- Bug #947906: An object oriented interface has been added to the calendar
1323 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001324 called as a script (e.g. via ``python -mcalendar``). Localized month and
1325 weekday names can be ouput (even if an exotic encoding is used) using
1326 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001327
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001328Build
1329-----
1330
Neal Norwitz602d3392006-03-31 08:21:40 +00001331- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1332 by using -mieee gcc option.
1333
Martin v. Löwis86d66262006-02-17 08:40:11 +00001334- Patch #1432345: Make python compile on DragonFly.
1335
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001336- Build support for Win64-AMD64 was added.
1337
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001338- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1339
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001340- Patch #881820: look for openpty and forkpty also in libbsd.
1341
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001342- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1343 The zlib module is now builtin on Windows.
1344
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001345- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1346
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001347- Bug #1189330: configure did not correctly determine the necessary
1348 value of LINKCC if python was built with GCC 4.0.
1349
Trent Mick8321b422005-07-26 02:29:21 +00001350- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1351 vulnerability in zlib 1.2.1 and 1.2.2.
1352
Brett Cannon08cd5982005-04-24 22:26:38 +00001353- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1354 flags that change binary compatibility. Changes were also made to
1355 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001356 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001357
Bob Ippolitoed233462005-03-29 13:47:59 +00001358- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1359 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1360 no longer exists). This configure patch makes things right.
1361
Martin v. Löwise2713be2005-03-08 15:03:08 +00001362- Bug #1158607: Build with --disable-unicode again.
1363
Brett Cannon46d96232005-02-16 00:07:19 +00001364- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1365 defined. Discovered as a result of not being able to build on OS X.
1366
Brett Cannon516592f2004-12-07 00:42:59 +00001367- setup.py now uses the directories specified in LDFLAGS using the -L option
1368 and in CPPFLAGS using the -I option for adding library and include
1369 directories, respectively, for compiling extension modules against. This has
1370 led to the core being compiled using the values in CPPFLAGS. It also removes
1371 the need for the special-casing of both DarwinPorts and Fink for darwin since
1372 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1373 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1374 Fink, ``-I/opt/local/include`` for DarwinPorts).
1375
Brett Cannon43802422005-02-10 20:48:03 +00001376- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1377 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1378 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1379 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001381C API
1382-----
1383
Tim Petersc9d78aa2006-03-26 23:27:58 +00001384- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1385 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1386 is obtained via the ``PyObject_`` family, it must be released via the
1387 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1388 always been officially true, but when Python's small-object allocator was
1389 introduced, an attempt was made to cater to a few extension modules
1390 discovered at the time that obtained memory via ``PyObject_New`` but
1391 released it via ``PyMem_DEL``. It's years later, and if such code still
1392 exists it will fail now (probably with segfaults, but calling wrong
1393 low-level memory management functions can yield many symptoms).
1394
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001395- Added a C API for set and frozenset objects.
1396
Raymond Hettinger66517482004-12-03 11:45:13 +00001397- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001399- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1400 mapping argument now. This string is used as a mapping table. Byte values
1401 greater than the length of the string and 0xFFFE are treated as undefined
1402 mappings.
