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
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +000078- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
79
Nick Coghlanc649ec52006-05-29 12:43:05 +000080- Patch #1478788 (modified version): The functional extension module has
81 been renamed to _functools and a functools Python wrapper module added.
82 This provides a home for additional function related utilities that are
83 not specifically about functional programming. See PEP 309.
84
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000085- Patch #1493701: performance enhancements for struct module.
86
Georg Brandl378d5922006-05-17 14:26:50 +000087- Patch #1490224: time.altzone is now set correctly on Cygwin.
88
Georg Brandl8d3342b2006-05-16 07:38:27 +000089- Patch #1435422: zlib's compress and decompress objects now have a
90 copy() method.
91
Neal Norwitz7a5fc282006-05-15 06:48:14 +000092- On Win32, os.listdir now supports arbitrarily-long Unicode path names
93 (up to the system limit of 32K characters).
94
95- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
96 As a result, these functions now raise WindowsError instead of OSError.
97
Tim Peters7a822da2006-05-25 21:50:17 +000098- ``time.clock()`` on Win64 should use the high-performance Windows
99 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
100 Windows platforms).
101
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000102- Calling Tk_Init twice is refused if the first call failed as that
103 may deadlock.
104
Nick Coghlanc649ec52006-05-29 12:43:05 +0000105
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000106Library
107-------
108
Martin v. Löwis3f767792006-06-04 19:36:28 +0000109- Patch #1359618: Speed up charmap encoder by using a trie structure
110 for lookup.
111
Tim Petersd609b1a2006-06-02 23:22:51 +0000112- The functions in the ``pprint`` module now sort dictionaries by key
113 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
114 if and only if its display required more than one line, although that
115 wasn't documented. The new behavior increases predictability; e.g.,
116 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
117
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000118- Patch #1497027: try HTTP digest auth before basic auth in urllib2
119 (thanks for J. J. Lee).
120
Georg Brandl2b330372006-05-28 20:23:12 +0000121- Patch #1496206: improve urllib2 handling of passwords with respect to
122 default HTTP and HTTPS ports.
123
George Yoshidaf3c65de2006-05-28 16:39:09 +0000124- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
125
Bob Ippolito7298f272006-05-23 18:43:47 +0000126- Patch #1281707: speed up gzip.readline.
127
Georg Brandlb89316f2006-05-17 15:51:16 +0000128- Patch #1180296: Two new functions were added to the locale module:
129 format_string() to get the effect of "format % items" but locale-aware,
130 and currency() to format a monetary number with currency sign.
131
Georg Brandle3a25832006-05-17 14:56:04 +0000132- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
133 and several features added, such as speed and geometry control.
134
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000135- Patch #1488881: add support for external file objects in bz2 compressed
136 tarfiles.
137
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000138- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
139 stdout arguments, making it possible to redirect input and output
140 for remote debugging.
141
142- Patch #1484695: Update the tarfile module to version 0.8. This fixes
143 a couple of issues, notably handling of long file names using the
144 GNU LONGNAME extension.
145
146- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
147 new flag when ``name`` is already the name of an option flag.
148
149- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
150 package.
151
152- Patch #1472854: make the rlcompleter.Completer class usable on non-
153 UNIX platforms.
154
155- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

161
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000162- Patch #1492356: Port to Windows CE.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000182What's New in Python 2.5 alpha 2?
183=================================
184
185*Release date: 27-APR-2006*
186
187Core and builtins
188-----------------
189
Thomas Heller1b046642006-04-18 18:51:06 +0000190- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
191 by converting these apis from macros into exported functions again:
192
193 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
194 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
195 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
196 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
197 PyRun_String Py_CompileString
198
Martin v. Löwis45294a92006-04-18 06:24:08 +0000199- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
200
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000201- All uses of PyStructSequence_InitType have been changed to initialize
202 the type objects only once, even if the interpreter is initialized
203 multiple times.
204
Neal Norwitz61546162006-04-14 05:20:28 +0000205- Bug #1454485, array.array('u') could crash the interpreter. This was
206 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
207 to unicode when it didn't make sense. 'u#' now requires a unicode string.
208
209- Py_UNICODE is unsigned. It was always documented as unsigned, but
210 due to a bug had a signed value in previous versions.
211
Tim Peters3a5e8b12006-04-11 01:44:07 +0000212- Patch #837242: ``id()`` of any Python object always gives a positive
213 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
214 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000215 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000216 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000217
Tim Peters3a5e8b12006-04-11 01:44:07 +0000218 def __hash__(self):
219 return id(self) # WRONG
220
221 because a hash result must be a (short) Python int but it was always
222 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000223 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000224 was always usable as a hash value before this patch. That's no longer
225 necessarily so.
226
227- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000228 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000229 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000230 #1454844)
231
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000232- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
233 involving generators that have paused outside of any ``try`` or ``with``
234 blocks. (In 2.5a1, a paused generator that was part of a reference
235 cycle could not be garbage collected, regardless of whether it was
236 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000238Extension Modules
239-----------------
240
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000241- Patch #1191065: Fix preprocessor problems on systems where recvfrom
242 is a macro.
243
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000244- Bug #1467952: os.listdir() now correctly raises an error if readdir()
245 fails with an error condition.
246
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000247- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
248
249- Bug #1117761: bsddb.*open() no longer raises an exception when using
250 the cachesize parameter.
251
252- Bug #1149413: bsddb.*open() no longer raises an exception when using
253 a temporary db (file=None) with the 'n' flag to truncate on open.
254
255- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
256 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000257
Armin Rigoa9017c32006-04-19 11:50:27 +0000258- Patch #1062014: AF_UNIX sockets under Linux have a special
259 abstract namespace that is now fully supported.
260
Anthony Baxter51bcb682006-04-05 14:51:42 +0000261Library
262-------
263
Tim Peters711bf302006-04-25 03:31:36 +0000264- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
265 a doctest to be skipped (the code is not run, and the expected output
266 or exception is ignored).
267
Nick Coghlanda2268f2006-04-24 04:37:15 +0000268- Fixed contextlib.nested to cope with exceptions being raised and
269 caught inside exit handlers.
270
Greg Wardab05edc2006-04-23 03:47:58 +0000271- Updated optparse module to Optik 1.5.1 (allow numeric constants in
272 hex, octal, or binary; add ``append_const`` action; keep going if
273 gettext cannot be imported; added ``OptionParser.destroy()`` method;
274 added ``epilog`` for better help generation).
275
Tim Peters21fbd572006-04-21 21:18:10 +0000276- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
277 called from a thread spawned as a side effect of importing a module.
278
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000279- The pydoc module now supports documenting packages contained in
280 .zip or .egg files.
281
282- The pkgutil module now has several new utility functions, such
283 as ``walk_packages()`` to support working with packages that are either
284 in the filesystem or zip files.
285
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000286- The mailbox module can now modify and delete messages from
287 mailboxes, in addition to simply reading them. Thanks to Gregory
288 K. Johnson for writing the code, and to the 2005 Google Summer of
289 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000290
Tim Petersc7605f22006-04-17 21:12:33 +0000291- The ``__del__`` method of class ``local`` in module ``_threading_local``
292 returned before accomplishing any of its intended cleanup.
293
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000294- Patch #790710: Add breakpoint command lists in pdb.
295
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000296- Patch #1063914: Add Tkinter.Misc.clipboard_get().
297
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000298- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
299
Anthony Baxtere29002c2006-04-12 12:07:31 +0000300- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
301 Windows. Bug #1469163.
302
Phillip J. Eby47032112006-04-11 01:07:43 +0000303- The warnings, linecache, inspect, traceback, site, and doctest modules
304 were updated to work correctly with modules imported from zipfiles or
305 via other PEP 302 __loader__ objects.
306
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000307- Patch #1467770: Reduce usage of subprocess._active to processes which
308 the application hasn't waited on.

319
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000320- The Makefile now has a reindent target, which runs reindent.py on
321 the library.
322

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000327- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
328 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000329 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000330 CXX from --with-cxx-main, see description in README.

Martin v. Löwis10acfd02006-04-10 12:39:36 +0000332- Patch #1429775: Link extension modules with the shared libpython.
333
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000334- Fixed a libffi build problem on MIPS systems.
335
Tim Peters8931ff12006-05-13 23:28:20 +0000336- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
337 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
338 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000340Tests
341-----
342
Nick Coghlanda2268f2006-04-24 04:37:15 +0000343- test_contextlib now checks contextlib.nested can cope with exceptions
344 being raised and caught inside exit handlers.
345
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000346- test_cmd_line now checks operation of the -m and -c command switches
347
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000348- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
349 it separately and by hand. It also wasn't cleaning up its changes to
350 the current Decimal context.
351
Thomas Woutersabd08882006-04-26 15:53:30 +0000352- regrtest.py now has a -M option to run tests that test the new limits of
353 containers, on 64-bit architectures. Running these tests is only sensible
354 on 64-bit machines with more than two gigabytes of memory. The argument
355 passed is the maximum amount of memory for the tests to use.

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

Anthony Baxter51bcb682006-04-05 14:51:42 +0000363Documentation
364-------------
365
Tim Petersb06d28c2006-05-12 01:57:59 +0000366- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
367
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000368- PEP 343: Added Context Types section to the library reference
369 and attempted to bring other PEP 343 related documentation into
370 line with the implementation and/or python-dev discussions.
371
Tim Peters8dc73d22006-04-24 02:03:16 +0000372- Bug #1337990: clarified that ``doctest`` does not support examples
373 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000376What's New in Python 2.5 alpha 1?
377=================================
378
Anthony Baxterebed3f62006-04-03 15:03:44 +0000379*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000380
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000381Core and builtins
382-----------------
383
Nick Coghlan43832302006-04-23 17:04:07 +0000384- PEP 338: -m command line switch now delegates to runpy.run_module
385 allowing it to support modules in packages and zipfiles
386
Martin v. Löwisc661b882006-04-20 04:54:23 +0000387- On Windows, .DLL is not an accepted file name extension for
388 extension modules anymore; extensions are only found if they
389 end in .PYD.
390
Martin v. Löwisea62d252006-04-03 10:56:49 +0000391- Bug #1421664: sys.stderr.encoding is now set to the same value as
392 sys.stdout.encoding.
393
Neal Norwitz92e212f2006-04-03 04:48:37 +0000394- __import__ accepts keyword arguments.
395
Georg Brandlccadf842006-03-31 18:54:53 +0000396- Patch #1460496: round() now accepts keyword arguments.
397
Anthony Baxter262c00a2006-03-30 10:53:17 +0000398- Fixed bug #1459029 - unicode reprs were double-escaped.
399
Hye-Shik Changd478f342006-03-23 12:32:36 +0000400- Patch #1396919: The system scope threads are reenabled on FreeBSD
401 5.4 and later versions.
402
Neal Norwitze98ccf62006-03-23 05:39:47 +0000403- Bug #1115379: Compiling a Unicode string with an encoding declaration
404 now gives a SyntaxError.
405
Georg Brandlabd1ff82006-03-18 07:59:59 +0000406- Previously, Python code had no easy way to access the contents of a
407 cell object. Now, a ``cell_contents`` attribute has been added
408 (closes patch #1170323).
409
Tim Peterscf79aac2006-03-16 01:14:46 +0000410- Patch #1123430: Python's small-object allocator now returns an arena to
411 the system ``free()`` when all memory within an arena becomes unused
412 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
413 freed. Some applications will see a drop in virtual memory size now,
414 especially long-running applications that, from time to time, temporarily
415 use a large number of small objects. Note that when Python returns an
416 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000417 platform C library will in turn return that memory to the operating system.
418 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000419 appears to be effective at least on Microsoft C and gcc-based systems.
420 Thanks to Evan Jones for hard work and patience.
421
Georg Brandl533ff6f2006-03-08 18:09:27 +0000422- Patch #1434038: property() now uses the getter's docstring if there is
423 no "doc" argument given. This makes it possible to legitimately use
424 property() as a decorator to produce a read-only property.
425
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000426- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
427 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
428 of requiring an int or long in slicing and a few other contexts, enabling
429 other objects (e.g. Numeric Python's integers) to be used as slice indices.
430
Neal Norwitz995acdf2006-03-07 05:01:00 +0000431- Fixed various bugs reported by Coverity's Prevent tool.
432
Brett Cannonbf364092006-03-01 04:25:17 +0000433- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
434 new exception base class, BaseException, which has a new message attribute.
435 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
436 Raising a string exception now raises a DeprecationWarning.
437
Thomas Woutersfb609f42006-02-28 16:37:25 +0000438- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
439 explicitly relative, using 'from .module import name' to mean 'from the same
440 package as this module is in. Imports without dots still default to the
441 old relative-then-absolute, unless 'from __future__ import
442 absolute_import' is used.
443
Brett Cannona7446e32006-02-27 23:39:10 +0000444- Properly check if 'warnings' raises an exception (usually when a filter set
445 to "error" is triggered) when raising a warning for raising string
446 exceptions.
447
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000448- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000449 The name was removed from Include/code.h.
450
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000451- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000452
Guido van Rossum1968ad32006-02-25 22:38:04 +0000453- Patch 1433928:
454 - The copy module now "copies" function objects (as atomic objects).
455 - dict.__getitem__ now looks for a __missing__ hook before raising
456 KeyError.
457
Tim Peters84ef21c2006-02-28 20:39:06 +0000458- PEP 343: with statement implemented. Needs ``from __future__ import
459 with_statement``. Use of 'with' as a variable will generate a warning.
460 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000461 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000462 The following objects have __context__ methods:
463 - The built-in file type.
464 - The thread.LockType type.
465 - The following types defined by the threading module:
466 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
467 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000468
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000469- Fix the encodings package codec search function to only search
470 inside its own package. Fixes problem reported in patch #1433198.
471
472 Note: Codec packages should implement and register their own
473 codec search function. PEP 100 has the details.
474
Tim Peters9ea89d22006-06-04 03:26:02 +0000475- PEP 353: Using ``Py_ssize_t`` as the index type.
476
477- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
478 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
479 now allow Python to make use of memory blocks exceeding 2**32 bytes for
480 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
481 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000482
Neal Norwitzfc76d632006-01-10 06:03:13 +0000483- Patch #1400181, fix unicode string formatting to not use the locale.
484 This is how string objects work. u'%f' could use , instead of .
485 for the decimal point. Now both strings and unicode always use periods.
486
Neal Norwitz671b9e32006-01-09 07:07:12 +0000487- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
488 configure would break checking curses.h.
489
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000490- Bug #959576: The pwd module is now builtin. This allows Python to be
491 built on UNIX platforms without $HOME set.
492
Neal Norwitzc10978f2005-12-19 06:07:16 +0000493- Bug #1072182, fix some potential problems if characters are signed.
494
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000495- Bug #889500, fix line number on SyntaxWarning for global declarations.
496
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000497- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
498
Neal Norwitze7214a12005-12-18 05:03:17 +0000499- Support for converting hex strings to floats no longer works.
500 This was not portable. float('0x3') now raises a ValueError.
501
Barry Warsaw2a38a862005-12-18 01:27:35 +0000502- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000503 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000504 is now displayed in interactive prompt banner.
505
Georg Brandlfa166682005-12-17 21:45:17 +0000506- Implementation of PEP 341 - Unification of try/except and try/finally.
507 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000508 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000509
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000510- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
511 now encodes backslash correctly.
512
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000513- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
514
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000515- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000516 and long longs.
517
Neal Norwitz67715f02005-11-09 06:59:35 +0000518- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000519 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000520 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000521
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000522- Replaced most Unicode charmap codecs with new ones using the
523 new Unicode translate string feature in the builtin charmap
524 codec; the codecs were created from the mapping tables available
525 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
526 encodings now include a mapping for the Apple logo)
527
Tim Peterse3547fd2005-12-16 23:13:57 +0000528- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000529
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000530- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000531
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000532- A new AST parser implementation was completed. The abstract
533 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000534 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000535
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000536- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000537 The following code now raises a SyntaxError: foo(a = i for i in range(10))
538
Neal Norwitz708e51a2005-10-03 04:48:15 +0000539- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
540
Neal Norwitz11bd1192005-10-03 00:54:56 +0000541- SF Bug #887946: fix segfault when redirecting stdin from a directory.
542 Provide a warning when a directory is passed on the command line.
543
Neal Norwitz40d37812005-10-02 01:48:49 +0000544- Fix segfault with invalid coding.
545
546- SF bug #772896: unknown encoding results in MemoryError.
547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000548- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000549 supported a __len__() method which evaluated to False when the iterator
550 was empty.
551
Guido van Rossum630db602005-09-20 18:49:54 +0000552- On 64-bit platforms, when __len__() returns a value that cannot be
553 represented as a C int, raise OverflowError.
554
Skip Montanarof8948ca2005-09-19 03:54:46 +0000555- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000556 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000557
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000558- SF bug #893549: parsing keyword arguments was broken with a few format
559 codes.
560
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000561- Changes donated by Elemental Security to make it work on AIX 5.3
562 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
563 bug #105470: test_pwd fails on 64bit system (Opteron).
564
Guido van Rossum539c6622005-09-14 17:49:54 +0000565- Changes donated by Elemental Security to make it work on HP-UX 11 on
566 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
567
Georg Brandl4550b8d2005-08-26 06:43:52 +0000568- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000569 (fixes bug #1119418).
570
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000571- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
572
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000573- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
574 exceptions that cause a function to exit.
575
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000576- The implementation of set() and frozenset() was revised to use its
577 own internal data structure. Memory consumption is reduced by 1/3
578 and there are modest speed-ups as well. The API is unchanged.
579
Tim Petersde7990b2005-07-17 23:45:23 +0000580- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
581
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000582- SF bug #1229429: PyObject_CallMethod failed to decrement some
583 reference counts in some error exit cases.
584
Tim Petersecc6e6a2005-07-10 22:30:55 +0000585- SF bug #1185883: Python's small-object memory allocator took over
586 a block managed by the platform C library whenever a realloc specified
587 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000588 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000589 portable way to copy data from the C-managed block into Python's
590 small-object space without risking a memory fault. Python's small-object
591 realloc now leaves such blocks under the control of the platform C
592 realloc.
593
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000594- SF bug #1232517: An overflow error was not detected properly when
595 attempting to convert a large float to an int in os.utime().
596
Raymond Hettinger3296e692005-06-29 23:29:56 +0000597- SF bug #1224347: hex longs now print with lowercase letters just
598 like their int counterparts.
599
Michael W. Hudson188d4362005-06-20 16:52:57 +0000600- SF bug #1163563: the original fix for bug #1010677 ("thread Module
601 Breaks PyGILState_Ensure()") broke badly in the case of multiple
602 interpreter states; back out that fix and do a better job (see
603 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
604 for a longer write-up of the problem).
605
Michael W. Hudsondf888462005-06-03 14:41:55 +0000606- SF patch #1180995: marshal now uses a binary format by default when
607 serializing floats.
608
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000609- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
610 the routines that promise to produce IEEE 754 binary representations
611 of floats now simply copy bytes around.
612
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000613- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
614 278.
615
Brett Cannonc3647ac2005-04-26 03:45:26 +0000616- patch #1109424: int, long, float, complex, and unicode now check for the
617 proper magic slot for type conversions when subclassed. Previously the
618 magic slot was ignored during conversion. Semantics now match the way
619 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000620 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000621 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000622 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000623
Barry Warsawc8d907c2005-04-19 23:43:40 +0000624- Descriptors defined in C with a PyGetSetDef structure, where the setter is
625 NULL, now raise an AttributeError when attempting to set or delete the
626 attribute. Previously a TypeError was raised, but this was inconsistent
627 with the equivalent pure-Python implementation.
628
Michael W. Hudson774479c2005-04-18 08:46:17 +0000629- It is now safe to call PyGILState_Release() before
630 PyEval_InitThreads() (note that if there is reason to believe there
631 are multiple threads around you still must call PyEval_InitThreads()
632 before using the Python API; this fix is for extension modules that
633 have no way of knowing if Python is multi-threaded yet).
634
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000635- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
636 disabled caused a crash.
637
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000638- Bug #1165306: instancemethod_new allowed the creation of a method
639 with im_class == im_self == NULL, which caused a crash when called.
640
Tim Petersecc6e6a2005-07-10 22:30:55 +0000641- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000642 fixes the crash seen in bug #1165761
643
Raymond Hettinger96229b12005-03-11 06:49:40 +0000644- Added two new builtins, any() and all().
645
Brett Cannon409d8f22005-03-05 06:47:57 +0000646- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000647 (e.g., ``class C(): pass`` is no longer a syntax error).
648 Patch #1176012 added support to the 'parser' module and 'compiler' package
649 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000650
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000651- Patch #1115086: Support PY_LONGLONG in structmember.
652
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000653- Bug #1155938: new style classes did not check that __init__() was
654 returning None.
655
Tim Petersecc6e6a2005-07-10 22:30:55 +0000656- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000657 ('\') with a specific error message.
658
Martin v. Löwisff232d72005-03-03 09:24:38 +0000659- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
660
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000661- Bug #1124295: the __name__ attribute of file objects was
662 inadvertently made inaccessible in restricted mode.
663
Tim Petersecc6e6a2005-07-10 22:30:55 +0000664- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000665 an ferror() call.
666
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000667- min() and max() now support key= arguments with the same meaning as in
668 list.sort().
669
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000670- The peephole optimizer now performs simple constant folding in expressions:
671 (2+3) --> (5).
672
Raymond Hettingera422c342005-01-11 03:03:27 +0000673- set and frozenset objects can now be marshalled. SF #1098985.
674
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000675- Bug #1077106: Poor argument checking could cause memory corruption
676 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000677
Jeremy Hyltonab630502005-02-04 18:44:06 +0000678- The parser did not complain about future statements in illegal
679 positions. It once again reports a syntax error if a future
680 statement occurs after anything other than a doc string.
681
Neil Schemenauercf52c072005-08-12 17:34:58 +0000682- Change the %s format specifier for str objects so that it returns a
683 unicode instance if the argument is not an instance of basestring and
684 calling __str__ on the argument returns a unicode instance.
685
Tim Petersf4e69282006-02-27 17:15:31 +0000686- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
687 current thread state when the auto-GIL-state machinery knows about
688 it (since the thread state is being deleted, continuing to remember it
689 can't help, but can hurt if another thread happens to get created with
690 the same thread id).
691

720 for applications that require this specific version (such as IDNA).
721
Neal Norwitzb62c4332006-03-04 18:35:47 +0000722- The timing module is no longer built by default. It was deprecated

Fred Drakead5177c2006-04-01 22:14:43 +0000890- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
891 now sport attributes that provide access to the parts of the result.
892
Georg Brandl7f6b67c2006-04-01 08:35:18 +0000893- Patch #1462498: sgmllib now handles entity and character references
894 in attribute values.
895
Anthony Baxterc51ee692006-04-01 00:57:31 +0000896- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000897 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000898 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000899 module will not be built.
900
Tim Petersc17976e2006-04-01 00:26:53 +0000901- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
902 aren't officially supported here, and trying to use them will probably
903 raise an exception some day. But dicts have been allowed, and "mostly
904 worked", so support for them won't go away without warning.
905
Georg Brandl338ef7d2006-03-31 18:42:16 +0000906- Bug #1445068: getpass.getpass() can now be given an explicit stream
907 argument to specify where to write the prompt.
908
Georg Brandl22ec80b2006-03-31 18:25:44 +0000909- Patch #1462313, bug #1443328: the pickle modules now can handle classes

915 key to be used for signing the uploaded code.
916
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +0000917- Queue.Queue objects now support .task_done() and .join() methods
918 to make it easier to monitor when daemon threads have completed
919 processing all enqueued tasks. Patch #1455676.
920
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +0000921- popen2.Popen objects now preserve the command in a .cmd attribute.
922
Thomas Hellerc61c0492006-03-22 10:09:27 +0000923- Added the ctypes ffi package.
924
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000925- email 4.0 package now integrated. This is largely the same as the email 3.0
926 package that was included in Python 2.3, except that PEP 8 module names are
927 now used (e.g. mail.message instead of email.Message). The MIME classes
928 have been moved to a subpackage (e.g. email.mime.text instead of
929 email.MIMEText). The old names are still supported for now. Several
930 deprecated Message methods have been removed and lots of bugs have been
931 fixed. More details can be found in the email package documentation.
932
Walter Dörwald40108c92006-03-27 08:15:44 +0000933- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
934 (a subclass of tuple) that provides incremental decoders and encoders
935 (a way to use stateful codecs without the stream API). Python functions
936 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
937 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
938 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000939
Walter Dörwald067db482006-03-15 22:17:27 +0000940- Patch #1359365: Calling next() on a closed StringIO.String object raises
941 a ValueError instead of a StopIteration now (like file and cString.String do).
942 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
943 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000944
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000945- A regrtest option -w was added to re-run failed tests in verbose mode.
946

948 interpreter to exit.
949
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000950- The function get_count() has been added to the gc module, and gc.collect()
951 grew an optional 'generation' argument.
952
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000953- A library msilib to generate Windows Installer files, and a distutils
954 command bdist_msi have been added.
955
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000956- PEP 343: new module contextlib.py defines decorator @contextmanager
957 and helpful context managers nested() and closing().
958
Martin v. Löwis415ed932006-02-27 19:56:30 +0000959- The compiler package now supports future imports after the module docstring.

971 current file number.
972

1013 LoadError as documented, instead of IOError. For compatibility,
1014 LoadError subclasses IOError.
1015
Brett Cannon3cbd0382005-12-16 22:49:23 +00001016- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001017 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1018 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1019 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1020 Ronald L. Rivest offered this advice for Python:
1021
1022 "The consensus of researchers in this area (at least as
1023 expressed at the NIST Hash Function Workshop 10/31/05),
1024 is that SHA-256 is a good choice for the time being, but
1025 that research should continue, and other alternatives may
1026 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001027
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001028- Added a subset of Fredrik Lundh's ElementTree package. Available

1081 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001082 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001083

1099 parameter, but uses the usual "kwargs=None".
1100
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001101- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1105 to W3C name (404 -> 'Not Found'). RFE #1216944.
1106
Georg Brandl9e43acf2005-07-04 17:16:07 +00001107- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1108 as this can cause problems with apps closing all file descriptors.

1121 Bug #1224621.
1122
Raymond Hettinger68c04532005-06-10 11:05:19 +00001123- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001124 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001125 the generate_tokens() function now accepts a callable argument that
1126 terminates by raising StopIteration.

1132
Skip Montanaro174dd222005-05-14 20:54:16 +00001133- Patch #1120353: The xmlrpclib module provides better, more transparent,
1134 support for datetime.{datetime,date,time} objects. With use_datetime set
1135 to True, applications shouldn't have to fiddle with the DateTime wrapper
1136 class at all.
1137
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001138- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbab41432005-02-05 01:31:19 +00001185- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1186
Guido van Rossumd0641422005-02-03 15:01:24 +00001187- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1188 disables recursive traversal through instance attributes, which can
1189 be exploited in various ways.
1190
Tim Peterse3547fd2005-12-16 23:13:57 +00001191- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001192 flags on the HTTP listening socket.
1193
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001194- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1195 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1196
Tim Peterse3547fd2005-12-16 23:13:57 +00001197- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001198 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1199

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001202- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1203
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001204- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1205
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001206- Enhancements to the csv module:
1207
1208 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001209 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001210 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001211 + Dialect parameter parsing has been re-implemented to improve error
1212 reporting.
1213 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1214 dictates.
1215 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001216 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001217 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001218 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1219 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001220 + reader now allows \r characters to be quoted (previously it only allowed
1221 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001222 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001223 + Dialect classes passed to the module are no longer instantiated by
1224 the module before being parsed (the former validation scheme required
1225 this, but the mechanism was unreliable).
1226 + The dialect registry now contains instances of the internal
1227 C-coded dialect type, rather than references to python objects.
1228 + the internal c-coded dialect type is now immutable.
1229 + register_dialect now accepts the same keyword dialect specifications
1230 as the reader and writer, allowing the user to register dialects
1231 without first creating a dialect class.
1232 + a configurable limit to the size of parsed fields has been added -
1233 previously, an unmatched quote character could result in the entire
1234 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001235 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001236 the parser field size limit (returning the former limit). The initial
1237 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001238 + A line_num attribute has been added to the reader object, which tracks
1239 the number of lines read from the source iterator. This is not
1240 the same as the number of records returned, as records can span
1241 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001242 + reader and writer objects were not being registered with the cyclic-GC.
1243 This has been fixed.
1244
Brett Cannone6539c42005-01-08 02:43:53 +00001245- _DummyThread objects in the threading module now delete self.__block that is
1246 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1247 lock primitives tend to be limited in number and thus should not be wasted on
1248 a _DummyThread object. Fixes bug #1089632.
1249
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001250- The imghdr module now detects Exif files.
1251
Raymond Hettinger6065d322004-12-20 23:51:53 +00001252- StringIO.truncate() now correctly adjusts the size attribute.
1253 (Bug #951915).
1254
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001255- locale.py now uses an updated locale alias table (built using
1256 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1257 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001258 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001259
Raymond Hettinger3557f422004-12-07 12:02:02 +00001260- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1261
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001262- the pickle module no longer accepts the deprecated None option in the
1263 args tuple returned by __reduce__().
1264
Brett Cannon84667c02004-12-07 03:25:18 +00001265- optparse now optionally imports gettext. This allows its use in setup.py.
1266
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001267- the pickle module no longer uses the deprecated bin parameter.
1268
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001269- the shelve module no longer uses the deprecated binary parameter.
1270
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001271- the pstats module no longer uses the deprecated ignore() method.
1272
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001273- the filecmp module no longer uses the deprecated use_statcache argument.
1274
Raymond Hettinger664347b2004-12-04 21:21:53 +00001275- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1276 extended or overridden by subclasses. Formerly, the subclassed method would
1277 be ignored by the rest of the module. (Bug #1078905).
1278
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001279- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001280 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001281
Walter Dörwald36733692004-12-22 12:50:50 +00001282- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1283 once when a size argument is given. This prevents a buffer overflow in the
1284 tokenizer with very long source lines.
1285
Barry Warsaw538561e2006-01-01 21:48:54 +00001286- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1287 immediately after creating the object, without any intervening
1288 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001289
Skip Montanaro05885812005-01-16 20:48:27 +00001290- The reconvert.quote function can now emit triple-quoted strings. The
1291 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001292
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001293- ``UserString.MutableString`` now supports negative indices in
1294 ``__setitem__`` and ``__delitem__``
1295
Greg Ward40407942005-03-05 02:53:17 +00001296- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1297 correctly.
1298
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001299- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1300 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1301 character even if the user has passed a size parameter to get a proper
1302 line ending. Remove the special handling of a "\r\n" that has been split
1303 between two lines.
1304
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001305- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1306 about illegal code points. The codec now supports PEP 293 style error
1307 handlers.
1308
Walter Dörwald78a78b02005-09-01 12:04:29 +00001309- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001310 from the input stream, so that the output is a byte string in the correct
1311 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001312
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001313- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1314 considering it exactly like a '*'.
1315
Walter Dörwald007f8df2005-10-09 19:42:27 +00001316- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1317 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001318
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001319- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1320
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001321- Patch #1413711: Certain patterns of differences were making difflib
1322 touch the recursion limit.
1323
Walter Dörwald58917a62006-03-31 15:26:22 +00001324- Bug #947906: An object oriented interface has been added to the calendar
1325 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001326 called as a script (e.g. via ``python -mcalendar``). Localized month and
1327 weekday names can be ouput (even if an exotic encoding is used) using
1328 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001329

1331-----
1332
Neal Norwitz602d3392006-03-31 08:21:40 +00001333- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1334 by using -mieee gcc option.
1335
Martin v. Löwis86d66262006-02-17 08:40:11 +00001336- Patch #1432345: Make python compile on DragonFly.
1337
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001338- Build support for Win64-AMD64 was added.
1339
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001340- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1341
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001342- Patch #881820: look for openpty and forkpty also in libbsd.
1343
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001344- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1345 The zlib module is now builtin on Windows.
1346
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001347- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1348
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001349- Bug #1189330: configure did not correctly determine the necessary
1350 value of LINKCC if python was built with GCC 4.0.
1351
Trent Mick8321b422005-07-26 02:29:21 +00001352- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1353 vulnerability in zlib 1.2.1 and 1.2.2.
1354
Brett Cannon08cd5982005-04-24 22:26:38 +00001355- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1356 flags that change binary compatibility. Changes were also made to
1357 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001358 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001359
Bob Ippolitoed233462005-03-29 13:47:59 +00001360- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1361 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1362 no longer exists). This configure patch makes things right.
1363
Martin v. Löwise2713be2005-03-08 15:03:08 +00001364- Bug #1158607: Build with --disable-unicode again.
1365
Brett Cannon46d96232005-02-16 00:07:19 +00001366- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1367 defined. Discovered as a result of not being able to build on OS X.
1368
Brett Cannon516592f2004-12-07 00:42:59 +00001369- setup.py now uses the directories specified in LDFLAGS using the -L option
1370 and in CPPFLAGS using the -I option for adding library and include
1371 directories, respectively, for compiling extension modules against. This has
1372 led to the core being compiled using the values in CPPFLAGS. It also removes
1373 the need for the special-casing of both DarwinPorts and Fink for darwin since
1374 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1375 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1376 Fink, ``-I/opt/local/include`` for DarwinPorts).
1377
Brett Cannon43802422005-02-10 20:48:03 +00001378- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1379 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1380 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1381 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001383C API
1384-----
1385
Tim Petersc9d78aa2006-03-26 23:27:58 +00001386- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1387 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1388 is obtained via the ``PyObject_`` family, it must be released via the
1389 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1390 always been officially true, but when Python's small-object allocator was
1391 introduced, an attempt was made to cater to a few extension modules
1392 discovered at the time that obtained memory via ``PyObject_New`` but
1393 released it via ``PyMem_DEL``. It's years later, and if such code still
1394 exists it will fail now (probably with segfaults, but calling wrong
1395 low-level memory management functions can yield many symptoms).
1396
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001397- Added a C API for set and frozenset objects.
1398
Raymond Hettinger66517482004-12-03 11:45:13 +00001399- Removed PyRange_New().
1400
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001401- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1402 mapping argument now. This string is used as a mapping table. Byte values
1403 greater than the length of the string and 0xFFFE are treated as undefined
1404 mappings.
