Nick Coghlanc649ec52006-05-29 12:43:05 +00007What's New in Python 2.5 beta 1?
Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================

Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Georg Brandlddbaa662006-06-04 21:56:52 +000015- Patch #1346214: Statements like "if 0: suite" are now again optimized
16 away like they were in Python 2.4.
17
Georg Brandlb7c8f542006-05-27 12:30:25 +000018- Builtin exceptions are now full-blown new-style classes instead of
19 instances pretending to be classes, which speeds up exception handling
20 by about 80% in comparison to 2.5a2.
21
Martin v. Löwisd004fc82006-05-27 08:36:52 +000022- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
23 Unicode 4.1.
24
Georg Brandlf4ef1162006-05-26 18:03:31 +000025- Patch #921466: sys.path_importer_cache is now used to cache valid and
26 invalid file paths for the built-in import machinery which leads to
27 fewer open calls on startup.
28
Tim Peters696cf432006-05-24 21:10:40 +000029- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
30 of-2 bases. The largest speedup is for inputs with about 1000 decimal
31 digits. Conversion from non-power-of-2 bases remains quadratic-time in
32 the number of input digits (it was and remains linear-time for bases
33 2, 4, 8, 16 and 32).
34
Tim Petersb713ec22006-05-23 18:45:30 +000035- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
36 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
37 an integer close to ``sys.maxint``. This was repaired by patch
38 #1335972, which also gives a nice speedup.
39
Richard Jonescebbefc2006-05-23 18:28:17 +000040- Patch #1337051: reduced size of frame objects.
41
42- PyErr_NewException now accepts a tuple of base classes as its
43 "base" parameter.
44
Richard Jones7c88dcc2006-05-23 10:37:38 +000045- Patch #876206: function call speedup by retaining allocated frame
46 objects.
47
Georg Brandl7b90e162006-05-18 07:01:27 +000048- Bug #1462152: file() now checks more thoroughly for invalid mode
49 strings and removes a possible "U" before passing the mode to the
50 C library function.
51
Neal Norwitz1004a532006-05-15 07:17:23 +000052- Patch #1488312, Fix memory alignment problem on SPARC in unicode
53
Neal Norwitz373f0a72006-05-15 07:04:36 +000054- Bug #1487966: Fix SystemError with conditional expression in assignment
55
Martin v. Löwis879768d2006-05-11 13:28:43 +000056- WindowsError now has two error code attributes: errno, which carries
57 the error values from errno.h, and winerror, which carries the error
58 values from winerror.h. Previous versions put the winerror.h values
59 (from GetLastError()) into the errno attribute.
60
Martin v. Löwis77736712006-05-04 05:51:03 +000061- Patch #1475845: Raise IndentationError for unexpected indent.
62
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000063- Patch #1479181: split open() and file() from being aliases for each other.
64
Tim Peters44bd9862006-06-01 13:49:23 +000065- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
66 methods were always silently ignored by dictionaries when comparing keys.
67 They are now passed through (except when using the C API function
68 ``PyDict_GetItem()``, whose semantics did not change).
69
70- Bug #1456209: In some obscure cases it was possible for a class with a
71 custom ``__eq__()`` method to confuse dict internals when class instances
72 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
73 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000075Extension Modules
76-----------------
77
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
Andrew MacIntyre6539d2d2006-06-04 12:31:09 +000090- Patch #1454481: thread stack size is now tunable at runtime for thread
91 enabled builds on Windows and systems with Posix threads support.
92
Neal Norwitz7a5fc282006-05-15 06:48:14 +000093- On Win32, os.listdir now supports arbitrarily-long Unicode path names
94 (up to the system limit of 32K characters).
95
96- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
97 As a result, these functions now raise WindowsError instead of OSError.
98
Tim Peters7a822da2006-05-25 21:50:17 +000099- ``time.clock()`` on Win64 should use the high-performance Windows
100 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
101 Windows platforms).
102
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000103- Calling Tk_Init twice is refused if the first call failed as that
104 may deadlock.
105

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000107Library
108-------
109
Martin v. Löwis3f767792006-06-04 19:36:28 +0000110- Patch #1359618: Speed up charmap encoder by using a trie structure
111 for lookup.
112
Tim Petersd609b1a2006-06-02 23:22:51 +0000113- The functions in the ``pprint`` module now sort dictionaries by key
114 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
115 if and only if its display required more than one line, although that
116 wasn't documented. The new behavior increases predictability; e.g.,
117 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
118
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000119- Patch #1497027: try HTTP digest auth before basic auth in urllib2
120 (thanks for J. J. Lee).
121
Georg Brandl2b330372006-05-28 20:23:12 +0000122- Patch #1496206: improve urllib2 handling of passwords with respect to
123 default HTTP and HTTPS ports.
124
George Yoshidaf3c65de2006-05-28 16:39:09 +0000125- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
126
Bob Ippolito7298f272006-05-23 18:43:47 +0000127- Patch #1281707: speed up gzip.readline.
128
Georg Brandlb89316f2006-05-17 15:51:16 +0000129- Patch #1180296: Two new functions were added to the locale module:
130 format_string() to get the effect of "format % items" but locale-aware,
131 and currency() to format a monetary number with currency sign.
132
Georg Brandle3a25832006-05-17 14:56:04 +0000133- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
134 and several features added, such as speed and geometry control.
135
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000136- Patch #1488881: add support for external file objects in bz2 compressed
137 tarfiles.
138
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000139- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
140 stdout arguments, making it possible to redirect input and output
141 for remote debugging.
142
143- Patch #1484695: Update the tarfile module to version 0.8. This fixes
144 a couple of issues, notably handling of long file names using the
145 GNU LONGNAME extension.
146
147- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
148 new flag when ``name`` is already the name of an option flag.
149
150- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
151 package.
152
153- Patch #1472854: make the rlcompleter.Completer class usable on non-
154 UNIX platforms.
155
156- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000183What's New in Python 2.5 alpha 2?
184=================================
185
186*Release date: 27-APR-2006*
187
188Core and builtins
189-----------------
190
Thomas Heller1b046642006-04-18 18:51:06 +0000191- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
192 by converting these apis from macros into exported functions again:
193
194 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
195 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
196 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
197 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
198 PyRun_String Py_CompileString
199
Martin v. Löwis45294a92006-04-18 06:24:08 +0000200- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
201
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000202- All uses of PyStructSequence_InitType have been changed to initialize
203 the type objects only once, even if the interpreter is initialized
204 multiple times.
205
Neal Norwitz61546162006-04-14 05:20:28 +0000206- Bug #1454485, array.array('u') could crash the interpreter. This was
207 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
208 to unicode when it didn't make sense. 'u#' now requires a unicode string.
209
210- Py_UNICODE is unsigned. It was always documented as unsigned, but
211 due to a bug had a signed value in previous versions.
212
Tim Peters3a5e8b12006-04-11 01:44:07 +0000213- Patch #837242: ``id()`` of any Python object always gives a positive
214 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
215 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000216 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000217 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000218
Tim Peters3a5e8b12006-04-11 01:44:07 +0000219 def __hash__(self):
220 return id(self) # WRONG
221
222 because a hash result must be a (short) Python int but it was always
223 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000224 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000225 was always usable as a hash value before this patch. That's no longer
226 necessarily so.
227
228- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000229 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000230 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000231 #1454844)
232
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000233- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
234 involving generators that have paused outside of any ``try`` or ``with``
235 blocks. (In 2.5a1, a paused generator that was part of a reference
236 cycle could not be garbage collected, regardless of whether it was
237 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000239Extension Modules
240-----------------
241
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000242- Patch #1191065: Fix preprocessor problems on systems where recvfrom
243 is a macro.
244
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000245- Bug #1467952: os.listdir() now correctly raises an error if readdir()
246 fails with an error condition.
247
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000248- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
249
250- Bug #1117761: bsddb.*open() no longer raises an exception when using
251 the cachesize parameter.
252
253- Bug #1149413: bsddb.*open() no longer raises an exception when using
254 a temporary db (file=None) with the 'n' flag to truncate on open.
255
256- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
257 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000258
Armin Rigoa9017c32006-04-19 11:50:27 +0000259- Patch #1062014: AF_UNIX sockets under Linux have a special
260 abstract namespace that is now fully supported.
261
Anthony Baxter51bcb682006-04-05 14:51:42 +0000262Library
263-------
264
Tim Peters711bf302006-04-25 03:31:36 +0000265- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
266 a doctest to be skipped (the code is not run, and the expected output
267 or exception is ignored).
268
Nick Coghlanda2268f2006-04-24 04:37:15 +0000269- Fixed contextlib.nested to cope with exceptions being raised and
270 caught inside exit handlers.
271
Greg Wardab05edc2006-04-23 03:47:58 +0000272- Updated optparse module to Optik 1.5.1 (allow numeric constants in
273 hex, octal, or binary; add ``append_const`` action; keep going if
274 gettext cannot be imported; added ``OptionParser.destroy()`` method;
275 added ``epilog`` for better help generation).
276
Tim Peters21fbd572006-04-21 21:18:10 +0000277- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
278 called from a thread spawned as a side effect of importing a module.
279
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000280- The pydoc module now supports documenting packages contained in
281 .zip or .egg files.
282
283- The pkgutil module now has several new utility functions, such
284 as ``walk_packages()`` to support working with packages that are either
285 in the filesystem or zip files.
286
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000287- The mailbox module can now modify and delete messages from
288 mailboxes, in addition to simply reading them. Thanks to Gregory
289 K. Johnson for writing the code, and to the 2005 Google Summer of
290 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000291
Tim Petersc7605f22006-04-17 21:12:33 +0000292- The ``__del__`` method of class ``local`` in module ``_threading_local``
293 returned before accomplishing any of its intended cleanup.
294
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000295- Patch #790710: Add breakpoint command lists in pdb.
296
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000297- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000299- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
300
Anthony Baxtere29002c2006-04-12 12:07:31 +0000301- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
302 Windows. Bug #1469163.
303
Phillip J. Eby47032112006-04-11 01:07:43 +0000304- The warnings, linecache, inspect, traceback, site, and doctest modules
305 were updated to work correctly with modules imported from zipfiles or
306 via other PEP 302 __loader__ objects.
307
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000308- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +0000321- The Makefile now has a reindent target, which runs reindent.py on
322 the library.
323

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000328- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
329 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000330 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000331 CXX from --with-cxx-main, see description in README.
332
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000333- Patch #1429775: Link extension modules with the shared libpython.
334
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000335- Fixed a libffi build problem on MIPS systems.
336
Tim Peters8931ff12006-05-13 23:28:20 +0000337- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
338 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
339 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000341Tests
342-----
343
Nick Coghlanda2268f2006-04-24 04:37:15 +0000344- test_contextlib now checks contextlib.nested can cope with exceptions
345 being raised and caught inside exit handlers.
346
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000347- test_cmd_line now checks operation of the -m and -c command switches
348
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000349- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
350 it separately and by hand. It also wasn't cleaning up its changes to
351 the current Decimal context.
352
Thomas Woutersabd08882006-04-26 15:53:30 +0000353- regrtest.py now has a -M option to run tests that test the new limits of
354 containers, on 64-bit architectures. Running these tests is only sensible
355 on 64-bit machines with more than two gigabytes of memory. The argument
356 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000364Documentation
365-------------
366
Tim Petersb06d28c2006-05-12 01:57:59 +0000367- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
368
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000369- PEP 343: Added Context Types section to the library reference
370 and attempted to bring other PEP 343 related documentation into
371 line with the implementation and/or python-dev discussions.
372
Tim Peters8dc73d22006-04-24 02:03:16 +0000373- Bug #1337990: clarified that ``doctest`` does not support examples
374 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000377What's New in Python 2.5 alpha 1?
378=================================
379
Anthony Baxterebed3f62006-04-03 15:03:44 +0000380*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000381
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000382Core and builtins
383-----------------
384
Nick Coghlan43832302006-04-23 17:04:07 +0000385- PEP 338: -m command line switch now delegates to runpy.run_module
386 allowing it to support modules in packages and zipfiles
387
Martin v. Löwisc661b882006-04-20 04:54:23 +0000388- On Windows, .DLL is not an accepted file name extension for
389 extension modules anymore; extensions are only found if they
390 end in .PYD.
391
Martin v. Löwisea62d252006-04-03 10:56:49 +0000392- Bug #1421664: sys.stderr.encoding is now set to the same value as
393 sys.stdout.encoding.
394
Neal Norwitz92e212f2006-04-03 04:48:37 +0000395- __import__ accepts keyword arguments.
396
Georg Brandlccadf842006-03-31 18:54:53 +0000397- Patch #1460496: round() now accepts keyword arguments.
398
Anthony Baxter262c00a2006-03-30 10:53:17 +0000399- Fixed bug #1459029 - unicode reprs were double-escaped.
400
Hye-Shik Changd478f342006-03-23 12:32:36 +0000401- Patch #1396919: The system scope threads are reenabled on FreeBSD
402 5.4 and later versions.
403
Neal Norwitze98ccf62006-03-23 05:39:47 +0000404- Bug #1115379: Compiling a Unicode string with an encoding declaration
405 now gives a SyntaxError.
406
Georg Brandlabd1ff82006-03-18 07:59:59 +0000407- Previously, Python code had no easy way to access the contents of a
408 cell object. Now, a ``cell_contents`` attribute has been added
409 (closes patch #1170323).
410
Tim Peterscf79aac2006-03-16 01:14:46 +0000411- Patch #1123430: Python's small-object allocator now returns an arena to
412 the system ``free()`` when all memory within an arena becomes unused
413 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
414 freed. Some applications will see a drop in virtual memory size now,
415 especially long-running applications that, from time to time, temporarily
416 use a large number of small objects. Note that when Python returns an
417 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000418 platform C library will in turn return that memory to the operating system.
419 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000420 appears to be effective at least on Microsoft C and gcc-based systems.
421 Thanks to Evan Jones for hard work and patience.
422
Georg Brandl533ff6f2006-03-08 18:09:27 +0000423- Patch #1434038: property() now uses the getter's docstring if there is
424 no "doc" argument given. This makes it possible to legitimately use
425 property() as a decorator to produce a read-only property.
426
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000427- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
428 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
429 of requiring an int or long in slicing and a few other contexts, enabling
430 other objects (e.g. Numeric Python's integers) to be used as slice indices.
431
Neal Norwitz995acdf2006-03-07 05:01:00 +0000432- Fixed various bugs reported by Coverity's Prevent tool.
433
Brett Cannonbf364092006-03-01 04:25:17 +0000434- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
435 new exception base class, BaseException, which has a new message attribute.
436 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
437 Raising a string exception now raises a DeprecationWarning.
438
Thomas Woutersfb609f42006-02-28 16:37:25 +0000439- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
440 explicitly relative, using 'from .module import name' to mean 'from the same
441 package as this module is in. Imports without dots still default to the
442 old relative-then-absolute, unless 'from __future__ import
443 absolute_import' is used.
444
Brett Cannona7446e32006-02-27 23:39:10 +0000445- Properly check if 'warnings' raises an exception (usually when a filter set
446 to "error" is triggered) when raising a warning for raising string
447 exceptions.
448
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000449- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000450 The name was removed from Include/code.h.
451
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000452- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000453
Guido van Rossum1968ad32006-02-25 22:38:04 +0000454- Patch 1433928:
455 - The copy module now "copies" function objects (as atomic objects).
456 - dict.__getitem__ now looks for a __missing__ hook before raising
457 KeyError.
458
Tim Peters84ef21c2006-02-28 20:39:06 +0000459- PEP 343: with statement implemented. Needs ``from __future__ import
460 with_statement``. Use of 'with' as a variable will generate a warning.
461 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000462 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000463 The following objects have __context__ methods:
464 - The built-in file type.
465 - The thread.LockType type.
466 - The following types defined by the threading module:
467 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
468 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000469
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000470- Fix the encodings package codec search function to only search
471 inside its own package. Fixes problem reported in patch #1433198.
472
473 Note: Codec packages should implement and register their own
474 codec search function. PEP 100 has the details.
475
Tim Peters9ea89d22006-06-04 03:26:02 +0000476- PEP 353: Using ``Py_ssize_t`` as the index type.
477
478- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
479 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
480 now allow Python to make use of memory blocks exceeding 2**32 bytes for
481 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
482 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000483
Neal Norwitzfc76d632006-01-10 06:03:13 +0000484- Patch #1400181, fix unicode string formatting to not use the locale.
485 This is how string objects work. u'%f' could use , instead of .
486 for the decimal point. Now both strings and unicode always use periods.
487
Neal Norwitz671b9e32006-01-09 07:07:12 +0000488- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
489 configure would break checking curses.h.
490
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000491- Bug #959576: The pwd module is now builtin. This allows Python to be
492 built on UNIX platforms without $HOME set.
493
Neal Norwitzc10978f2005-12-19 06:07:16 +0000494- Bug #1072182, fix some potential problems if characters are signed.
495
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000496- Bug #889500, fix line number on SyntaxWarning for global declarations.
497
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000498- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
499
Neal Norwitze7214a12005-12-18 05:03:17 +0000500- Support for converting hex strings to floats no longer works.
501 This was not portable. float('0x3') now raises a ValueError.
502
Barry Warsaw2a38a862005-12-18 01:27:35 +0000503- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000504 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000505 is now displayed in interactive prompt banner.
506
Georg Brandlfa166682005-12-17 21:45:17 +0000507- Implementation of PEP 341 - Unification of try/except and try/finally.
508 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000509 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000510
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000511- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
512 now encodes backslash correctly.
513
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000514- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
515
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000516- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000517 and long longs.
518
Neal Norwitz67715f02005-11-09 06:59:35 +0000519- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000520 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000521 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000522
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000523- Replaced most Unicode charmap codecs with new ones using the
524 new Unicode translate string feature in the builtin charmap
525 codec; the codecs were created from the mapping tables available
526 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
527 encodings now include a mapping for the Apple logo)
528
Tim Peterse3547fd2005-12-16 23:13:57 +0000529- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000530
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000531- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000532
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000533- A new AST parser implementation was completed. The abstract
534 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000535 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000536
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000537- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000538 The following code now raises a SyntaxError: foo(a = i for i in range(10))
539
Neal Norwitz708e51a2005-10-03 04:48:15 +0000540- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
541
Neal Norwitz11bd1192005-10-03 00:54:56 +0000542- SF Bug #887946: fix segfault when redirecting stdin from a directory.
543 Provide a warning when a directory is passed on the command line.
544
Neal Norwitz40d37812005-10-02 01:48:49 +0000545- Fix segfault with invalid coding.
546
547- SF bug #772896: unknown encoding results in MemoryError.
548
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000549- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000550 supported a __len__() method which evaluated to False when the iterator
551 was empty.
552
Guido van Rossum630db602005-09-20 18:49:54 +0000553- On 64-bit platforms, when __len__() returns a value that cannot be
554 represented as a C int, raise OverflowError.
555
Skip Montanarof8948ca2005-09-19 03:54:46 +0000556- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000557 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000558
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000559- SF bug #893549: parsing keyword arguments was broken with a few format
560 codes.
561
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000562- Changes donated by Elemental Security to make it work on AIX 5.3
563 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
564 bug #105470: test_pwd fails on 64bit system (Opteron).
565
Guido van Rossum539c6622005-09-14 17:49:54 +0000566- Changes donated by Elemental Security to make it work on HP-UX 11 on
567 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
568
Georg Brandl4550b8d2005-08-26 06:43:52 +0000569- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000570 (fixes bug #1119418).
571
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000572- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
573
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000574- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
575 exceptions that cause a function to exit.
576
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000577- The implementation of set() and frozenset() was revised to use its
578 own internal data structure. Memory consumption is reduced by 1/3
579 and there are modest speed-ups as well. The API is unchanged.
580
Tim Petersde7990b2005-07-17 23:45:23 +0000581- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
582
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000583- SF bug #1229429: PyObject_CallMethod failed to decrement some
584 reference counts in some error exit cases.
585
Tim Petersecc6e6a2005-07-10 22:30:55 +0000586- SF bug #1185883: Python's small-object memory allocator took over
587 a block managed by the platform C library whenever a realloc specified
588 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000589 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000590 portable way to copy data from the C-managed block into Python's
591 small-object space without risking a memory fault. Python's small-object
592 realloc now leaves such blocks under the control of the platform C
593 realloc.
594
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000595- SF bug #1232517: An overflow error was not detected properly when
596 attempting to convert a large float to an int in os.utime().
597
Raymond Hettinger3296e692005-06-29 23:29:56 +0000598- SF bug #1224347: hex longs now print with lowercase letters just
599 like their int counterparts.
600
Michael W. Hudson188d4362005-06-20 16:52:57 +0000601- SF bug #1163563: the original fix for bug #1010677 ("thread Module
602 Breaks PyGILState_Ensure()") broke badly in the case of multiple
603 interpreter states; back out that fix and do a better job (see
604 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
605 for a longer write-up of the problem).
606
Michael W. Hudsondf888462005-06-03 14:41:55 +0000607- SF patch #1180995: marshal now uses a binary format by default when
608 serializing floats.
609
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000610- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
611 the routines that promise to produce IEEE 754 binary representations
612 of floats now simply copy bytes around.
613
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000614- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
615 278.
616
Brett Cannonc3647ac2005-04-26 03:45:26 +0000617- patch #1109424: int, long, float, complex, and unicode now check for the
618 proper magic slot for type conversions when subclassed. Previously the
619 magic slot was ignored during conversion. Semantics now match the way
620 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000621 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000622 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000623 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000624
Barry Warsawc8d907c2005-04-19 23:43:40 +0000625- Descriptors defined in C with a PyGetSetDef structure, where the setter is
626 NULL, now raise an AttributeError when attempting to set or delete the
627 attribute. Previously a TypeError was raised, but this was inconsistent
628 with the equivalent pure-Python implementation.
629
Michael W. Hudson774479c2005-04-18 08:46:17 +0000630- It is now safe to call PyGILState_Release() before
631 PyEval_InitThreads() (note that if there is reason to believe there
632 are multiple threads around you still must call PyEval_InitThreads()
633 before using the Python API; this fix is for extension modules that
634 have no way of knowing if Python is multi-threaded yet).
635
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000636- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
637 disabled caused a crash.
638
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000639- Bug #1165306: instancemethod_new allowed the creation of a method
640 with im_class == im_self == NULL, which caused a crash when called.
641
Tim Petersecc6e6a2005-07-10 22:30:55 +0000642- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000643 fixes the crash seen in bug #1165761
644
Raymond Hettinger96229b12005-03-11 06:49:40 +0000645- Added two new builtins, any() and all().
646
Brett Cannon409d8f22005-03-05 06:47:57 +0000647- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000648 (e.g., ``class C(): pass`` is no longer a syntax error).
649 Patch #1176012 added support to the 'parser' module and 'compiler' package
650 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000651
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000652- Patch #1115086: Support PY_LONGLONG in structmember.
653
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000654- Bug #1155938: new style classes did not check that __init__() was
655 returning None.
656
Tim Petersecc6e6a2005-07-10 22:30:55 +0000657- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000658 ('\') with a specific error message.
659
Martin v. Löwisff232d72005-03-03 09:24:38 +0000660- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
661
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000662- Bug #1124295: the __name__ attribute of file objects was
663 inadvertently made inaccessible in restricted mode.
664
Tim Petersecc6e6a2005-07-10 22:30:55 +0000665- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000666 an ferror() call.
667
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000668- min() and max() now support key= arguments with the same meaning as in
669 list.sort().
670
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000671- The peephole optimizer now performs simple constant folding in expressions:
672 (2+3) --> (5).
673
Raymond Hettingera422c342005-01-11 03:03:27 +0000674- set and frozenset objects can now be marshalled. SF #1098985.
675
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000676- Bug #1077106: Poor argument checking could cause memory corruption
677 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000678
Jeremy Hyltonab630502005-02-04 18:44:06 +0000679- The parser did not complain about future statements in illegal
680 positions. It once again reports a syntax error if a future
681 statement occurs after anything other than a doc string.
682
Neil Schemenauercf52c072005-08-12 17:34:58 +0000683- Change the %s format specifier for str objects so that it returns a
684 unicode instance if the argument is not an instance of basestring and
685 calling __str__ on the argument returns a unicode instance.
686
Tim Petersf4e69282006-02-27 17:15:31 +0000687- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
688 current thread state when the auto-GIL-state machinery knows about
689 it (since the thread state is being deleted, continuing to remember it
690 can't help, but can hurt if another thread happens to get created with
691 the same thread id).
692

721 for applications that require this specific version (such as IDNA).
722
Neal Norwitzb62c4332006-03-04 18:35:47 +0000723- The timing module is no longer built by default. It was deprecated

Anthony Baxter93f5b932006-04-03 08:05:07 +0000887- The email module's parsedate_tz function now sets the daylight savings
888 flag to -1 (unknown) since it can't tell from the date whether it should
889 be set.
890
Fred Drakead5177c2006-04-01 22:14:43 +0000891- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
892 now sport attributes that provide access to the parts of the result.
893

895 in attribute values.
896
Anthony Baxterc51ee692006-04-01 00:57:31 +0000897- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000898 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000899 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000900 module will not be built.
901
Tim Petersc17976e2006-04-01 00:26:53 +0000902- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
903 aren't officially supported here, and trying to use them will probably
904 raise an exception some day. But dicts have been allowed, and "mostly
905 worked", so support for them won't go away without warning.
906
Georg Brandl338ef7d2006-03-31 18:42:16 +0000907- Bug #1445068: getpass.getpass() can now be given an explicit stream
908 argument to specify where to write the prompt.
909
Georg Brandl22ec80b2006-03-31 18:25:44 +0000910- Patch #1462313, bug #1443328: the pickle modules now can handle classes

916 key to be used for signing the uploaded code.
917
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000918- Queue.Queue objects now support .task_done() and .join() methods
919 to make it easier to monitor when daemon threads have completed
920 processing all enqueued tasks. Patch #1455676.
921
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000922- popen2.Popen objects now preserve the command in a .cmd attribute.
923
Thomas Hellerc61c0492006-03-22 10:09:27 +0000924- Added the ctypes ffi package.
925
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000926- email 4.0 package now integrated. This is largely the same as the email 3.0
927 package that was included in Python 2.3, except that PEP 8 module names are
928 now used (e.g. mail.message instead of email.Message). The MIME classes
929 have been moved to a subpackage (e.g. email.mime.text instead of
930 email.MIMEText). The old names are still supported for now. Several
931 deprecated Message methods have been removed and lots of bugs have been
932 fixed. More details can be found in the email package documentation.
933
Walter Dörwald40108c92006-03-27 08:15:44 +0000934- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
935 (a subclass of tuple) that provides incremental decoders and encoders
936 (a way to use stateful codecs without the stream API). Python functions
937 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
938 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
939 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000940
Walter Dörwald067db482006-03-15 22:17:27 +0000941- Patch #1359365: Calling next() on a closed StringIO.String object raises
942 a ValueError instead of a StopIteration now (like file and cString.String do).
943 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
944 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000945
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000946- A regrtest option -w was added to re-run failed tests in verbose mode.

949 interpreter to exit.
950
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000951- The function get_count() has been added to the gc module, and gc.collect()
952 grew an optional 'generation' argument.
953
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000954- A library msilib to generate Windows Installer files, and a distutils
955 command bdist_msi have been added.
956

958 and helpful context managers nested() and closing().
959
Martin v. Löwis415ed932006-02-27 19:56:30 +0000960- The compiler package now supports future imports after the module docstring.

1007 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00001008

1014 LoadError as documented, instead of IOError. For compatibility,
1015 LoadError subclasses IOError.
1016

Tim Peterse3547fd2005-12-16 23:13:57 +00001018 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1019 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1020 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1021 Ronald L. Rivest offered this advice for Python:
1022
1023 "The consensus of researchers in this area (at least as
1024 expressed at the NIST Hash Function Workshop 10/31/05),
1025 is that SHA-256 is a good choice for the time being, but
1026 that research should continue, and other alternatives may
1027 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001028
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001029- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda05834e2005-10-09 19:38:21 +00001083 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001084

1100 parameter, but uses the usual "kwargs=None".
1101

1122 Bug #1224621.
1123
Raymond Hettinger68c04532005-06-10 11:05:19 +00001124- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001125 roundtrip from lexed tokens back to Python source code. In addition,

1137 class at all.
1138
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001139- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbab41432005-02-05 01:31:19 +00001186- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1187
Guido van Rossumd0641422005-02-03 15:01:24 +00001188- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1189 disables recursive traversal through instance attributes, which can
1190 be exploited in various ways.
1191
Tim Peterse3547fd2005-12-16 23:13:57 +00001192- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001193 flags on the HTTP listening socket.
1194
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001195- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1196 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1197
Tim Peterse3547fd2005-12-16 23:13:57 +00001198- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001199 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001203- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1204
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001205- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1206
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001207- Enhancements to the csv module:
1208
1209 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001210 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001211 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001212 + Dialect parameter parsing has been re-implemented to improve error
1213 reporting.
1214 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1215 dictates.
1216 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001217 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001218 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001219 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1220 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001221 + reader now allows \r characters to be quoted (previously it only allowed
1222 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001223 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001224 + Dialect classes passed to the module are no longer instantiated by
1225 the module before being parsed (the former validation scheme required
1226 this, but the mechanism was unreliable).
1227 + The dialect registry now contains instances of the internal
1228 C-coded dialect type, rather than references to python objects.
1229 + the internal c-coded dialect type is now immutable.
1230 + register_dialect now accepts the same keyword dialect specifications
1231 as the reader and writer, allowing the user to register dialects
1232 without first creating a dialect class.
1233 + a configurable limit to the size of parsed fields has been added -
1234 previously, an unmatched quote character could result in the entire
1235 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001236 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001237 the parser field size limit (returning the former limit). The initial
1238 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001239 + A line_num attribute has been added to the reader object, which tracks
1240 the number of lines read from the source iterator. This is not
1241 the same as the number of records returned, as records can span
1242 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001243 + reader and writer objects were not being registered with the cyclic-GC.
1244 This has been fixed.
1245
Brett Cannone6539c42005-01-08 02:43:53 +00001246- _DummyThread objects in the threading module now delete self.__block that is
1247 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1248 lock primitives tend to be limited in number and thus should not be wasted on
1249 a _DummyThread object. Fixes bug #1089632.
1250
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001251- The imghdr module now detects Exif files.
1252
Raymond Hettinger6065d322004-12-20 23:51:53 +00001253- StringIO.truncate() now correctly adjusts the size attribute.
1254 (Bug #951915).
1255
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001256- locale.py now uses an updated locale alias table (built using
1257 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1258 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001259 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001260
Raymond Hettinger3557f422004-12-07 12:02:02 +00001261- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1262
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001263- the pickle module no longer accepts the deprecated None option in the
1264 args tuple returned by __reduce__().
1265
Brett Cannon84667c02004-12-07 03:25:18 +00001266- optparse now optionally imports gettext. This allows its use in setup.py.
1267
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001268- the pickle module no longer uses the deprecated bin parameter.
1269
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001270- the shelve module no longer uses the deprecated binary parameter.
1271
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001272- the pstats module no longer uses the deprecated ignore() method.
1273
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001274- the filecmp module no longer uses the deprecated use_statcache argument.
1275
Raymond Hettinger664347b2004-12-04 21:21:53 +00001276- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1277 extended or overridden by subclasses. Formerly, the subclassed method would
1278 be ignored by the rest of the module. (Bug #1078905).
1279
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001280- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001281 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001282
Walter Dörwald36733692004-12-22 12:50:50 +00001283- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1284 once when a size argument is given. This prevents a buffer overflow in the
1285 tokenizer with very long source lines.
1286
Barry Warsaw538561e2006-01-01 21:48:54 +00001287- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1288 immediately after creating the object, without any intervening
1289 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001290
Skip Montanaro05885812005-01-16 20:48:27 +00001291- The reconvert.quote function can now emit triple-quoted strings. The
1292 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001293
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001294- ``UserString.MutableString`` now supports negative indices in
1295 ``__setitem__`` and ``__delitem__``
1296
Greg Ward40407942005-03-05 02:53:17 +00001297- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1298 correctly.
1299
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001300- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1301 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1302 character even if the user has passed a size parameter to get a proper
1303 line ending. Remove the special handling of a "\r\n" that has been split
1304 between two lines.
1305
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001306- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1307 about illegal code points. The codec now supports PEP 293 style error
1308 handlers.
1309
Walter Dörwald78a78b02005-09-01 12:04:29 +00001310- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001311 from the input stream, so that the output is a byte string in the correct
1312 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001313
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001314- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1315 considering it exactly like a '*'.
1316
Walter Dörwald007f8df2005-10-09 19:42:27 +00001317- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1318 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001319
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001320- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1321
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001322- Patch #1413711: Certain patterns of differences were making difflib
1323 touch the recursion limit.
1324
Walter Dörwald58917a62006-03-31 15:26:22 +00001325- Bug #947906: An object oriented interface has been added to the calendar
1326 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001327 called as a script (e.g. via ``python -mcalendar``). Localized month and
1328 weekday names can be ouput (even if an exotic encoding is used) using
1329 special classes that use unicode.

1333
Neal Norwitz602d3392006-03-31 08:21:40 +00001334- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1335 by using -mieee gcc option.
1336
Martin v. Löwis86d66262006-02-17 08:40:11 +00001337- Patch #1432345: Make python compile on DragonFly.
1338
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001339- Build support for Win64-AMD64 was added.
1340
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001341- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1342
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001343- Patch #881820: look for openpty and forkpty also in libbsd.
1344
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001345- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1346 The zlib module is now builtin on Windows.
1347
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001348- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1349
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001350- Bug #1189330: configure did not correctly determine the necessary
1351 value of LINKCC if python was built with GCC 4.0.
1352
Trent Mick8321b422005-07-26 02:29:21 +00001353- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1354 vulnerability in zlib 1.2.1 and 1.2.2.
1355
Brett Cannon08cd5982005-04-24 22:26:38 +00001356- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1357 flags that change binary compatibility. Changes were also made to
1358 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001359 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001360
Bob Ippolitoed233462005-03-29 13:47:59 +00001361- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1362 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1363 no longer exists). This configure patch makes things right.
1364
Martin v. Löwise2713be2005-03-08 15:03:08 +00001365- Bug #1158607: Build with --disable-unicode again.
1366
Brett Cannon46d96232005-02-16 00:07:19 +00001367- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1368 defined. Discovered as a result of not being able to build on OS X.
1369
Brett Cannon516592f2004-12-07 00:42:59 +00001370- setup.py now uses the directories specified in LDFLAGS using the -L option
1371 and in CPPFLAGS using the -I option for adding library and include
1372 directories, respectively, for compiling extension modules against. This has
1373 led to the core being compiled using the values in CPPFLAGS. It also removes
1374 the need for the special-casing of both DarwinPorts and Fink for darwin since
1375 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1376 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1377 Fink, ``-I/opt/local/include`` for DarwinPorts).
1378
Brett Cannon43802422005-02-10 20:48:03 +00001379- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1380 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1381 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1382 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001384C API
1385-----
1386
Tim Petersc9d78aa2006-03-26 23:27:58 +00001387- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1388 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1389 is obtained via the ``PyObject_`` family, it must be released via the
1390 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1391 always been officially true, but when Python's small-object allocator was
1392 introduced, an attempt was made to cater to a few extension modules
1393 discovered at the time that obtained memory via ``PyObject_New`` but
1394 released it via ``PyMem_DEL``. It's years later, and if such code still
1395 exists it will fail now (probably with segfaults, but calling wrong
1396 low-level memory management functions can yield many symptoms).
1397
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001398- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001402- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1403 mapping argument now. This string is used as a mapping table. Byte values
1404 greater than the length of the string and 0xFFFE are treated as undefined
1405 mappings.
