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
Brett Cannonde3b0522006-06-08 17:00:45 +000015- Buffer objects, at the C level, never used the char buffer
16 implementation even when the char buffer for the wrapped object was
17 explicitly requested (originally returned the read or write buffer).
18 Now a TypeError is raised if the char buffer is not present but is
19 requested.
20
Georg Brandlddbaa662006-06-04 21:56:52 +000021- Patch #1346214: Statements like "if 0: suite" are now again optimized
22 away like they were in Python 2.4.
23
Georg Brandlb7c8f542006-05-27 12:30:25 +000024- Builtin exceptions are now full-blown new-style classes instead of
25 instances pretending to be classes, which speeds up exception handling
26 by about 80% in comparison to 2.5a2.
27
Martin v. Löwisd004fc82006-05-27 08:36:52 +000028- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
29 Unicode 4.1.
30
Georg Brandlf4ef1162006-05-26 18:03:31 +000031- Patch #921466: sys.path_importer_cache is now used to cache valid and
32 invalid file paths for the built-in import machinery which leads to
33 fewer open calls on startup.
34
Tim Peters696cf432006-05-24 21:10:40 +000035- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
36 of-2 bases. The largest speedup is for inputs with about 1000 decimal
37 digits. Conversion from non-power-of-2 bases remains quadratic-time in
38 the number of input digits (it was and remains linear-time for bases
39 2, 4, 8, 16 and 32).
40
Tim Petersb713ec22006-05-23 18:45:30 +000041- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
42 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
43 an integer close to ``sys.maxint``. This was repaired by patch
44 #1335972, which also gives a nice speedup.
45
Richard Jonescebbefc2006-05-23 18:28:17 +000046- Patch #1337051: reduced size of frame objects.
47
48- PyErr_NewException now accepts a tuple of base classes as its
49 "base" parameter.
50
Richard Jones7c88dcc2006-05-23 10:37:38 +000051- Patch #876206: function call speedup by retaining allocated frame
52 objects.
53
Georg Brandl7b90e162006-05-18 07:01:27 +000054- Bug #1462152: file() now checks more thoroughly for invalid mode
55 strings and removes a possible "U" before passing the mode to the
56 C library function.
57
Neal Norwitz1004a532006-05-15 07:17:23 +000058- Patch #1488312, Fix memory alignment problem on SPARC in unicode
59
Neal Norwitz373f0a72006-05-15 07:04:36 +000060- Bug #1487966: Fix SystemError with conditional expression in assignment
61
Martin v. Löwis879768d2006-05-11 13:28:43 +000062- WindowsError now has two error code attributes: errno, which carries
63 the error values from errno.h, and winerror, which carries the error
64 values from winerror.h. Previous versions put the winerror.h values
65 (from GetLastError()) into the errno attribute.
66
Martin v. Löwis77736712006-05-04 05:51:03 +000067- Patch #1475845: Raise IndentationError for unexpected indent.
68
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000069- Patch #1479181: split open() and file() from being aliases for each other.
70
Tim Peters44bd9862006-06-01 13:49:23 +000071- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
72 methods were always silently ignored by dictionaries when comparing keys.
73 They are now passed through (except when using the C API function
74 ``PyDict_GetItem()``, whose semantics did not change).
75
76- Bug #1456209: In some obscure cases it was possible for a class with a
77 custom ``__eq__()`` method to confuse dict internals when class instances
78 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
79 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000081Extension Modules
82-----------------
83
Brett Cannon6ee7d012006-06-08 16:23:04 +000084- Change binascii.hexlify to accept a read-only buffer instead of only a char
85 buffer and actually follow its documentation.
86
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +000087- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
88
Nick Coghlanc649ec52006-05-29 12:43:05 +000089- Patch #1478788 (modified version): The functional extension module has
90 been renamed to _functools and a functools Python wrapper module added.
91 This provides a home for additional function related utilities that are
92 not specifically about functional programming. See PEP 309.
93
Bob Ippolito7ccc95a2006-05-23 19:11:34 +000094- Patch #1493701: performance enhancements for struct module.
95
Georg Brandl378d5922006-05-17 14:26:50 +000096- Patch #1490224: time.altzone is now set correctly on Cygwin.
97
Georg Brandl8d3342b2006-05-16 07:38:27 +000098- Patch #1435422: zlib's compress and decompress objects now have a
99 copy() method.
100
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000101- On Win32, os.listdir now supports arbitrarily-long Unicode path names
102 (up to the system limit of 32K characters).
103
104- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
105 As a result, these functions now raise WindowsError instead of OSError.
106
Tim Peters7a822da2006-05-25 21:50:17 +0000107- ``time.clock()`` on Win64 should use the high-performance Windows
108 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
109 Windows platforms).
110
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000111- Calling Tk_Init twice is refused if the first call failed as that
112 may deadlock.
113
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000114- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
115 accept it without potentially using an uninitialized pointer.
116
117- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
118 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
119 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000120
Gregory P. Smith372b5832006-06-05 18:48:21 +0000121- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000122 [pybsddb project SF patch number 1466734]
123
Gregory P. Smith372b5832006-06-05 18:48:21 +0000124- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
125 parameter is supplied. [SF pybsddb bug #1477863]
126
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000127- bsddb: the __len__ method of a DB object has been fixed to return correct
128 results. It could previously incorrectly return 0 in some cases.
129 Fixes SF bug 1493322 (pybsddb bug 1184012).
130
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000131- bsddb: the bsddb.dbtables Modify method now raises the proper error and
132 aborts the db transaction safely when a modifier callback fails.
133 Fixes SF python patch/bug #1408584.
134
Gregory P. Smith372b5832006-06-05 18:48:21 +0000135
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000136Library
137-------
138
Nick Coghlan676725d2006-06-08 13:54:49 +0000139- The functions update_wrapper() and wraps() have been added to the functools
140 module. These make it easier to copy relevant metadata from the original
141 function when writing wrapper functions.
142
Tim Petersd6a9eef2006-06-05 01:48:21 +0000143- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
144 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000145
Martin v. Löwis3f767792006-06-04 19:36:28 +0000146- Patch #1359618: Speed up charmap encoder by using a trie structure
147 for lookup.
148
Tim Petersd609b1a2006-06-02 23:22:51 +0000149- The functions in the ``pprint`` module now sort dictionaries by key
150 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
151 if and only if its display required more than one line, although that
152 wasn't documented. The new behavior increases predictability; e.g.,
153 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
154
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000155- Patch #1497027: try HTTP digest auth before basic auth in urllib2
156 (thanks for J. J. Lee).
157
Georg Brandl2b330372006-05-28 20:23:12 +0000158- Patch #1496206: improve urllib2 handling of passwords with respect to
159 default HTTP and HTTPS ports.
160
George Yoshidaf3c65de2006-05-28 16:39:09 +0000161- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
162
Bob Ippolito7298f272006-05-23 18:43:47 +0000163- Patch #1281707: speed up gzip.readline.
164
Georg Brandlb89316f2006-05-17 15:51:16 +0000165- Patch #1180296: Two new functions were added to the locale module:
166 format_string() to get the effect of "format % items" but locale-aware,
167 and currency() to format a monetary number with currency sign.
168
Georg Brandle3a25832006-05-17 14:56:04 +0000169- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
170 and several features added, such as speed and geometry control.
171
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000172- Patch #1488881: add support for external file objects in bz2 compressed
173 tarfiles.
174
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000175- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
176 stdout arguments, making it possible to redirect input and output
177 for remote debugging.
178
179- Patch #1484695: Update the tarfile module to version 0.8. This fixes
180 a couple of issues, notably handling of long file names using the
181 GNU LONGNAME extension.
182
183- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
184 new flag when ``name`` is already the name of an option flag.
185
186- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
187 package.
188
189- Patch #1472854: make the rlcompleter.Completer class usable on non-
190 UNIX platforms.
191
192- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
193
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000194- Bug #1472827: correctly escape newlines and tabs in attribute values in
195 the saxutils.XMLGenerator class.
196

199-----
200
Georg Brandl66a0dbb2006-06-08 12:54:13 +0000201- Bug #1502728: Correctly link against librt library on HP-UX.
202
Martin v. Löwis222c5152006-06-03 07:37:13 +0000203- OpenBSD 3.9 is supported now.
204
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000205- Patch #1492356: Port to Windows CE.
206
Neal Norwitz58e28882006-05-19 07:00:58 +0000207- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
208
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000209- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000225What's New in Python 2.5 alpha 2?
226=================================
227
228*Release date: 27-APR-2006*
229
230Core and builtins
231-----------------
232
Thomas Heller1b046642006-04-18 18:51:06 +0000233- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
234 by converting these apis from macros into exported functions again:
235
236 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
237 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
238 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
239 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
240 PyRun_String Py_CompileString
241
Martin v. Löwis45294a92006-04-18 06:24:08 +0000242- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
243
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000244- All uses of PyStructSequence_InitType have been changed to initialize
245 the type objects only once, even if the interpreter is initialized
246 multiple times.
247
Neal Norwitz61546162006-04-14 05:20:28 +0000248- Bug #1454485, array.array('u') could crash the interpreter. This was
249 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
250 to unicode when it didn't make sense. 'u#' now requires a unicode string.
251
252- Py_UNICODE is unsigned. It was always documented as unsigned, but
253 due to a bug had a signed value in previous versions.
254
Tim Peters3a5e8b12006-04-11 01:44:07 +0000255- Patch #837242: ``id()`` of any Python object always gives a positive
256 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
257 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000258 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000259 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000260
Tim Peters3a5e8b12006-04-11 01:44:07 +0000261 def __hash__(self):
262 return id(self) # WRONG
263
264 because a hash result must be a (short) Python int but it was always
265 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000266 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000267 was always usable as a hash value before this patch. That's no longer
268 necessarily so.
269
270- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000271 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000272 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000273 #1454844)
274
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000275- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
276 involving generators that have paused outside of any ``try`` or ``with``
277 blocks. (In 2.5a1, a paused generator that was part of a reference
278 cycle could not be garbage collected, regardless of whether it was
279 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000281Extension Modules
282-----------------
283
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000284- Patch #1191065: Fix preprocessor problems on systems where recvfrom
285 is a macro.
286
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000287- Bug #1467952: os.listdir() now correctly raises an error if readdir()
288 fails with an error condition.
289
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000290- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
291
292- Bug #1117761: bsddb.*open() no longer raises an exception when using
293 the cachesize parameter.
294
295- Bug #1149413: bsddb.*open() no longer raises an exception when using
296 a temporary db (file=None) with the 'n' flag to truncate on open.
297
298- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
299 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000300
Armin Rigoa9017c32006-04-19 11:50:27 +0000301- Patch #1062014: AF_UNIX sockets under Linux have a special
302 abstract namespace that is now fully supported.
303
Anthony Baxter51bcb682006-04-05 14:51:42 +0000304Library
305-------
306
Tim Peters711bf302006-04-25 03:31:36 +0000307- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
308 a doctest to be skipped (the code is not run, and the expected output
309 or exception is ignored).
310
Nick Coghlanda2268f2006-04-24 04:37:15 +0000311- Fixed contextlib.nested to cope with exceptions being raised and
312 caught inside exit handlers.
313
Greg Wardab05edc2006-04-23 03:47:58 +0000314- Updated optparse module to Optik 1.5.1 (allow numeric constants in
315 hex, octal, or binary; add ``append_const`` action; keep going if
316 gettext cannot be imported; added ``OptionParser.destroy()`` method;
317 added ``epilog`` for better help generation).
318
Tim Peters21fbd572006-04-21 21:18:10 +0000319- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
320 called from a thread spawned as a side effect of importing a module.
321
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000322- The pydoc module now supports documenting packages contained in
323 .zip or .egg files.
324
325- The pkgutil module now has several new utility functions, such
326 as ``walk_packages()`` to support working with packages that are either
327 in the filesystem or zip files.
328
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000329- The mailbox module can now modify and delete messages from
330 mailboxes, in addition to simply reading them. Thanks to Gregory
331 K. Johnson for writing the code, and to the 2005 Google Summer of

359
Anthony Baxter51bcb682006-04-05 14:51:42 +0000360Build
361-----
362
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000363- The Makefile now has a reindent target, which runs reindent.py on
364 the library.
365
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000366- Patch #1470875: Building Python with MS Free Compiler
367
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000368- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000369
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000370- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
371 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000372 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000373 CXX from --with-cxx-main, see description in README.
374
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000375- Patch #1429775: Link extension modules with the shared libpython.
376
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000377- Fixed a libffi build problem on MIPS systems.
378
Tim Peters8931ff12006-05-13 23:28:20 +0000379- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
380 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
381 and "%zu" for unsigned integers of type ``size_t``.
382
Anthony Baxter51bcb682006-04-05 14:51:42 +0000383Tests
384-----
385
Nick Coghlanda2268f2006-04-24 04:37:15 +0000386- test_contextlib now checks contextlib.nested can cope with exceptions
387 being raised and caught inside exit handlers.
388
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000389- test_cmd_line now checks operation of the -m and -c command switches
390
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000391- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
392 it separately and by hand. It also wasn't cleaning up its changes to
393 the current Decimal context.
394
Thomas Woutersabd08882006-04-26 15:53:30 +0000395- regrtest.py now has a -M option to run tests that test the new limits of
396 containers, on 64-bit architectures. Running these tests is only sensible
397 on 64-bit machines with more than two gigabytes of memory. The argument
398 passed is the maximum amount of memory for the tests to use.

407-------------
408
Tim Petersb06d28c2006-05-12 01:57:59 +0000409- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
410
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000411- PEP 343: Added Context Types section to the library reference
412 and attempted to bring other PEP 343 related documentation into
413 line with the implementation and/or python-dev discussions.
414
Tim Peters8dc73d22006-04-24 02:03:16 +0000415- Bug #1337990: clarified that ``doctest`` does not support examples
416 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000419What's New in Python 2.5 alpha 1?
420=================================
421
Anthony Baxterebed3f62006-04-03 15:03:44 +0000422*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000423
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000424Core and builtins
425-----------------
426
Nick Coghlan43832302006-04-23 17:04:07 +0000427- PEP 338: -m command line switch now delegates to runpy.run_module
428 allowing it to support modules in packages and zipfiles
429
Martin v. Löwisc661b882006-04-20 04:54:23 +0000430- On Windows, .DLL is not an accepted file name extension for
431 extension modules anymore; extensions are only found if they
432 end in .PYD.
433
Martin v. Löwisea62d252006-04-03 10:56:49 +0000434- Bug #1421664: sys.stderr.encoding is now set to the same value as
435 sys.stdout.encoding.
436
Neal Norwitz92e212f2006-04-03 04:48:37 +0000437- __import__ accepts keyword arguments.
438
Georg Brandlccadf842006-03-31 18:54:53 +0000439- Patch #1460496: round() now accepts keyword arguments.
440
Anthony Baxter262c00a2006-03-30 10:53:17 +0000441- Fixed bug #1459029 - unicode reprs were double-escaped.
442
Hye-Shik Changd478f342006-03-23 12:32:36 +0000443- Patch #1396919: The system scope threads are reenabled on FreeBSD
444 5.4 and later versions.
445
Neal Norwitze98ccf62006-03-23 05:39:47 +0000446- Bug #1115379: Compiling a Unicode string with an encoding declaration
447 now gives a SyntaxError.
448
Georg Brandlabd1ff82006-03-18 07:59:59 +0000449- Previously, Python code had no easy way to access the contents of a
450 cell object. Now, a ``cell_contents`` attribute has been added
451 (closes patch #1170323).
452
Tim Peterscf79aac2006-03-16 01:14:46 +0000453- Patch #1123430: Python's small-object allocator now returns an arena to
454 the system ``free()`` when all memory within an arena becomes unused
455 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
456 freed. Some applications will see a drop in virtual memory size now,
457 especially long-running applications that, from time to time, temporarily
458 use a large number of small objects. Note that when Python returns an
459 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000460 platform C library will in turn return that memory to the operating system.
461 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000462 appears to be effective at least on Microsoft C and gcc-based systems.
463 Thanks to Evan Jones for hard work and patience.
464
Georg Brandl533ff6f2006-03-08 18:09:27 +0000465- Patch #1434038: property() now uses the getter's docstring if there is
466 no "doc" argument given. This makes it possible to legitimately use
467 property() as a decorator to produce a read-only property.
468
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000469- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
470 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
471 of requiring an int or long in slicing and a few other contexts, enabling
472 other objects (e.g. Numeric Python's integers) to be used as slice indices.
473
Neal Norwitz995acdf2006-03-07 05:01:00 +0000474- Fixed various bugs reported by Coverity's Prevent tool.
475
Brett Cannonbf364092006-03-01 04:25:17 +0000476- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
477 new exception base class, BaseException, which has a new message attribute.
478 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
479 Raising a string exception now raises a DeprecationWarning.
480
Thomas Woutersfb609f42006-02-28 16:37:25 +0000481- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
482 explicitly relative, using 'from .module import name' to mean 'from the same
483 package as this module is in. Imports without dots still default to the
484 old relative-then-absolute, unless 'from __future__ import
485 absolute_import' is used.
486
Brett Cannona7446e32006-02-27 23:39:10 +0000487- Properly check if 'warnings' raises an exception (usually when a filter set
488 to "error" is triggered) when raising a warning for raising string
489 exceptions.
490
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000491- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000492 The name was removed from Include/code.h.
493
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000494- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000495
Guido van Rossum1968ad32006-02-25 22:38:04 +0000496- Patch 1433928:
497 - The copy module now "copies" function objects (as atomic objects).
498 - dict.__getitem__ now looks for a __missing__ hook before raising
499 KeyError.
500
Tim Peters84ef21c2006-02-28 20:39:06 +0000501- PEP 343: with statement implemented. Needs ``from __future__ import
502 with_statement``. Use of 'with' as a variable will generate a warning.
503 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000504 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000505 The following objects have __context__ methods:
506 - The built-in file type.
507 - The thread.LockType type.
508 - The following types defined by the threading module:
509 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
510 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000511
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000512- Fix the encodings package codec search function to only search
513 inside its own package. Fixes problem reported in patch #1433198.
514
515 Note: Codec packages should implement and register their own
516 codec search function. PEP 100 has the details.
517
Tim Peters9ea89d22006-06-04 03:26:02 +0000518- PEP 353: Using ``Py_ssize_t`` as the index type.
519
520- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
521 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
522 now allow Python to make use of memory blocks exceeding 2**32 bytes for
523 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
524 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000525
Neal Norwitzfc76d632006-01-10 06:03:13 +0000526- Patch #1400181, fix unicode string formatting to not use the locale.
527 This is how string objects work. u'%f' could use , instead of .
528 for the decimal point. Now both strings and unicode always use periods.
529
Neal Norwitz671b9e32006-01-09 07:07:12 +0000530- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
531 configure would break checking curses.h.
532
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000533- Bug #959576: The pwd module is now builtin. This allows Python to be
534 built on UNIX platforms without $HOME set.
535
Neal Norwitzc10978f2005-12-19 06:07:16 +0000536- Bug #1072182, fix some potential problems if characters are signed.
537
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000538- Bug #889500, fix line number on SyntaxWarning for global declarations.
539
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000540- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
541
Neal Norwitze7214a12005-12-18 05:03:17 +0000542- Support for converting hex strings to floats no longer works.
543 This was not portable. float('0x3') now raises a ValueError.
544
Barry Warsaw2a38a862005-12-18 01:27:35 +0000545- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000546 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000547 is now displayed in interactive prompt banner.
548
Georg Brandlfa166682005-12-17 21:45:17 +0000549- Implementation of PEP 341 - Unification of try/except and try/finally.
550 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000551 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000552
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000553- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
554 now encodes backslash correctly.
555
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000556- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
557
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000558- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000559 and long longs.
560
Neal Norwitz67715f02005-11-09 06:59:35 +0000561- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000562 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000563 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000564
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000565- Replaced most Unicode charmap codecs with new ones using the
566 new Unicode translate string feature in the builtin charmap
567 codec; the codecs were created from the mapping tables available
568 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
569 encodings now include a mapping for the Apple logo)
570
Tim Peterse3547fd2005-12-16 23:13:57 +0000571- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000572
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000573- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000574
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000575- A new AST parser implementation was completed. The abstract
576 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000577 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000578
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000579- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000580 The following code now raises a SyntaxError: foo(a = i for i in range(10))
581
Neal Norwitz708e51a2005-10-03 04:48:15 +0000582- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
583
Neal Norwitz11bd1192005-10-03 00:54:56 +0000584- SF Bug #887946: fix segfault when redirecting stdin from a directory.
585 Provide a warning when a directory is passed on the command line.
586
Neal Norwitz40d37812005-10-02 01:48:49 +0000587- Fix segfault with invalid coding.
588
589- SF bug #772896: unknown encoding results in MemoryError.
590
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000591- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000592 supported a __len__() method which evaluated to False when the iterator
593 was empty.
594
Guido van Rossum630db602005-09-20 18:49:54 +0000595- On 64-bit platforms, when __len__() returns a value that cannot be
596 represented as a C int, raise OverflowError.
597
Skip Montanarof8948ca2005-09-19 03:54:46 +0000598- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000599 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000600
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000601- SF bug #893549: parsing keyword arguments was broken with a few format
602 codes.
603
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000604- Changes donated by Elemental Security to make it work on AIX 5.3
605 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
606 bug #105470: test_pwd fails on 64bit system (Opteron).
607
Guido van Rossum539c6622005-09-14 17:49:54 +0000608- Changes donated by Elemental Security to make it work on HP-UX 11 on
609 Itanium2 with HP's 64-bit compiler (SF patch #1225212).

Georg Brandl4550b8d2005-08-26 06:43:52 +0000611- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000612 (fixes bug #1119418).
613
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000614- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
615
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000616- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
617 exceptions that cause a function to exit.
618
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000619- The implementation of set() and frozenset() was revised to use its
620 own internal data structure. Memory consumption is reduced by 1/3
621 and there are modest speed-ups as well. The API is unchanged.
622
Tim Petersde7990b2005-07-17 23:45:23 +0000623- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
624
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000625- SF bug #1229429: PyObject_CallMethod failed to decrement some
626 reference counts in some error exit cases.
627
Tim Petersecc6e6a2005-07-10 22:30:55 +0000628- SF bug #1185883: Python's small-object memory allocator took over
629 a block managed by the platform C library whenever a realloc specified
630 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000631 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000632 portable way to copy data from the C-managed block into Python's
633 small-object space without risking a memory fault. Python's small-object
634 realloc now leaves such blocks under the control of the platform C
635 realloc.
636
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000637- SF bug #1232517: An overflow error was not detected properly when
638 attempting to convert a large float to an int in os.utime().
639
Raymond Hettinger3296e692005-06-29 23:29:56 +0000640- SF bug #1224347: hex longs now print with lowercase letters just
641 like their int counterparts.
642
Michael W. Hudson188d4362005-06-20 16:52:57 +0000643- SF bug #1163563: the original fix for bug #1010677 ("thread Module
644 Breaks PyGILState_Ensure()") broke badly in the case of multiple
645 interpreter states; back out that fix and do a better job (see
646 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
647 for a longer write-up of the problem).
648
Michael W. Hudsondf888462005-06-03 14:41:55 +0000649- SF patch #1180995: marshal now uses a binary format by default when
650 serializing floats.
651
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000652- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
653 the routines that promise to produce IEEE 754 binary representations
654 of floats now simply copy bytes around.
655
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000656- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
657 278.
658
Brett Cannonc3647ac2005-04-26 03:45:26 +0000659- patch #1109424: int, long, float, complex, and unicode now check for the
660 proper magic slot for type conversions when subclassed. Previously the
661 magic slot was ignored during conversion. Semantics now match the way
662 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000663 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000664 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000665 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000666
Barry Warsawc8d907c2005-04-19 23:43:40 +0000667- Descriptors defined in C with a PyGetSetDef structure, where the setter is
668 NULL, now raise an AttributeError when attempting to set or delete the
669 attribute. Previously a TypeError was raised, but this was inconsistent
670 with the equivalent pure-Python implementation.
671
Michael W. Hudson774479c2005-04-18 08:46:17 +0000672- It is now safe to call PyGILState_Release() before
673 PyEval_InitThreads() (note that if there is reason to believe there
674 are multiple threads around you still must call PyEval_InitThreads()
675 before using the Python API; this fix is for extension modules that
676 have no way of knowing if Python is multi-threaded yet).
677
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000678- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
679 disabled caused a crash.
680
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000681- Bug #1165306: instancemethod_new allowed the creation of a method
682 with im_class == im_self == NULL, which caused a crash when called.
683
Tim Petersecc6e6a2005-07-10 22:30:55 +0000684- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000685 fixes the crash seen in bug #1165761
686
Raymond Hettinger96229b12005-03-11 06:49:40 +0000687- Added two new builtins, any() and all().
688
Brett Cannon409d8f22005-03-05 06:47:57 +0000689- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000690 (e.g., ``class C(): pass`` is no longer a syntax error).
691 Patch #1176012 added support to the 'parser' module and 'compiler' package
692 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000693
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000694- Patch #1115086: Support PY_LONGLONG in structmember.
695
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000696- Bug #1155938: new style classes did not check that __init__() was
697 returning None.
698
Tim Petersecc6e6a2005-07-10 22:30:55 +0000699- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000700 ('\') with a specific error message.
701
Martin v. Löwisff232d72005-03-03 09:24:38 +0000702- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
703
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000704- Bug #1124295: the __name__ attribute of file objects was
705 inadvertently made inaccessible in restricted mode.
706
Tim Petersecc6e6a2005-07-10 22:30:55 +0000707- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000708 an ferror() call.
709
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000710- min() and max() now support key= arguments with the same meaning as in
711 list.sort().
712
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000713- The peephole optimizer now performs simple constant folding in expressions:
714 (2+3) --> (5).
715
Raymond Hettingera422c342005-01-11 03:03:27 +0000716- set and frozenset objects can now be marshalled. SF #1098985.
717
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000718- Bug #1077106: Poor argument checking could cause memory corruption
719 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000720
Jeremy Hyltonab630502005-02-04 18:44:06 +0000721- The parser did not complain about future statements in illegal
722 positions. It once again reports a syntax error if a future
723 statement occurs after anything other than a doc string.
724
Neil Schemenauercf52c072005-08-12 17:34:58 +0000725- Change the %s format specifier for str objects so that it returns a
726 unicode instance if the argument is not an instance of basestring and
727 calling __str__ on the argument returns a unicode instance.
728
Tim Petersf4e69282006-02-27 17:15:31 +0000729- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
730 current thread state when the auto-GIL-state machinery knows about
731 it (since the thread state is being deleted, continuing to remember it
732 can't help, but can hurt if another thread happens to get created with
733 the same thread id).
734
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000735Extension Modules
736-----------------
737
Georg Brandl43f08a82006-03-31 18:01:16 +0000738- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000747
Neal Norwitz10be10c2006-03-16 06:50:13 +0000748- Everything under lib-old was removed. This includes the following modules:
749 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000750 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,

752
753- The following modules were removed: regsub, reconvert, regex, regex_syntax.
754
755- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000756 is deprecated. The undocumented re.engine variable no longer exists.
757

759 SS2 (single-shift 2) escape sequences correctly.
760
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000761- The unicodedata module was updated to the 4.1 version of the Unicode
762 database. The 3.2 version is still available as unicodedata.db_3_2_0
763 for applications that require this specific version (such as IDNA).
764
Neal Norwitzb62c4332006-03-04 18:35:47 +0000765- The timing module is no longer built by default. It was deprecated
766 in PEP 4 in Python 2.0 or earlier.
767
Guido van Rossum1968ad32006-02-25 22:38:04 +0000768- Patch 1433928: Added a new type, defaultdict, to the collections module.
769 This uses the new __missing__ hook behavior added to dict (see above).
770
Georg Brandldbd83392006-02-20 09:42:33 +0000771- Bug #854823: socketmodule now builds on Sun platforms even when
772 INET_ADDRSTRLEN is not defined.
773
Georg Brandlf4f44152006-02-18 22:29:33 +0000774- Patch #1393157: os.startfile() now has an optional argument to specify
775 a "command verb" to invoke on the file.
776
Neal Norwitz082b2df2006-02-07 07:04:46 +0000777- Bug #876637, prevent stack corruption when socket descriptor

781 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
782 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
783
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000784- Patch #1422385: The nis module now supports access to domains other
785 than the system default domain.
786
Martin v. Löwis14694662006-02-03 12:54:16 +0000787- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
788 are reported, the limit on path name lengths is removed, and stat reports
789 WindowsError now (instead of OSError).
790

884
Raymond Hettinger984f9bb2005-03-09 16:38:48 +0000885- operator.itemgetter() and operator.attrgetter() now support retrieving
886 multiple fields. This provides direct support for sorting on multiple

Raymond Hettingerb2594052004-12-05 09:25:51 +0000912- itertools.islice() now accepts None for the start and step arguments.
913 This allows islice() to work more readily with slices:
914 islice(s.start, s.stop, s.step)
915
Skip Montanaro0af3ade2005-01-13 04:12:31 +0000916- datetime.datetime() now has a strptime class method which can be used to

923-------
924
Nick Coghlan43832302006-04-23 17:04:07 +0000925- PEP 338: new module runpy defines a run_module function to support
926 executing modules which provide access to source code or a code object
927 via the PEP 302 import mechanisms.
928

937 in attribute values.
938
Anthony Baxterc51ee692006-04-01 00:57:31 +0000939- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000940 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000941 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000942 module will not be built.
943
Tim Petersc17976e2006-04-01 00:26:53 +0000944- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
945 aren't officially supported here, and trying to use them will probably
946 raise an exception some day. But dicts have been allowed, and "mostly
947 worked", so support for them won't go away without warning.
948
Georg Brandl338ef7d2006-03-31 18:42:16 +0000949- Bug #1445068: getpass.getpass() can now be given an explicit stream
950 argument to specify where to write the prompt.
951
Georg Brandl22ec80b2006-03-31 18:25:44 +0000952- Patch #1462313, bug #1443328: the pickle modules now can handle classes

967
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000968- email 4.0 package now integrated. This is largely the same as the email 3.0
969 package that was included in Python 2.3, except that PEP 8 module names are
970 now used (e.g. mail.message instead of email.Message). The MIME classes
971 have been moved to a subpackage (e.g. email.mime.text instead of
972 email.MIMEText). The old names are still supported for now. Several
973 deprecated Message methods have been removed and lots of bugs have been
974 fixed. More details can be found in the email package documentation.
975
Walter Dörwald40108c92006-03-27 08:15:44 +0000976- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
977 (a subclass of tuple) that provides incremental decoders and encoders
978 (a way to use stateful codecs without the stream API). Python functions
979 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
980 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
981 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000982
Walter Dörwald067db482006-03-15 22:17:27 +0000983- Patch #1359365: Calling next() on a closed StringIO.String object raises
984 a ValueError instead of a StopIteration now (like file and cString.String do).
985 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
986 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000987
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000988- A regrtest option -w was added to re-run failed tests in verbose mode.

1061 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1062 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1063 Ronald L. Rivest offered this advice for Python:
1064
1065 "The consensus of researchers in this area (at least as
1066 expressed at the NIST Hash Function Workshop 10/31/05),
1067 is that SHA-256 is a good choice for the time being, but
1068 that research should continue, and other alternatives may
1069 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001070
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001071- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00001155
Georg Brandl2f210b62005-06-26 22:09:06 +00001156- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1157
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001158- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1159 error messages.
1160
Georg Brandl379f99d2005-06-26 21:09:38 +00001161- Bug #1108948: Cookie.py produced invalid JavaScript code.
1162
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001163- The tokenize module now detects and reports indentation errors.
1164 Bug #1224621.
1165
Raymond Hettinger68c04532005-06-10 11:05:19 +00001166- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001167 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001168 the generate_tokens() function now accepts a callable argument that
1169 terminates by raising StopIteration.
1170
Georg Brandl9166e1a2005-06-04 09:20:03 +00001171- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1172
Georg Brandl268e61c2005-06-03 14:28:50 +00001173- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1174 component of the path.
1175
Skip Montanaro174dd222005-05-14 20:54:16 +00001176- Patch #1120353: The xmlrpclib module provides better, more transparent,
1177 support for datetime.{datetime,date,time} objects. With use_datetime set
1178 to True, applications shouldn't have to fiddle with the DateTime wrapper
1179 class at all.
1180
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001181- distutils.commands.upload was added to support uploading distribution
1182 files to PyPI.
1183
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001184- distutils.commands.register now encodes the data as UTF-8 before posting
1185 them to PyPI.
1186
Raymond Hettinger267b8682005-03-27 10:47:39 +00001187- decimal operator and comparison methods now return NotImplemented
1188 instead of raising a TypeError when interacting with other types. This
1189 allows other classes to implement __radd__ style methods and have them
1190 work as expected.
1191
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001192- Bug #1163325: Decimal infinities failed to hash. Attempting to
1193 hash a NaN raised an InvalidOperation instead of a TypeError.
1194
Tim Petersecc6e6a2005-07-10 22:30:55 +00001195- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001196 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1197

1201 to build.
1202
Martin v. Löwis637431b2005-03-03 23:12:42 +00001203- Patch #1103407: Properly deal with tarfile iterators when untarring

Raymond Hettingerbab41432005-02-05 01:31:19 +00001228- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1229
Guido van Rossumd0641422005-02-03 15:01:24 +00001230- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1231 disables recursive traversal through instance attributes, which can
1232 be exploited in various ways.
1233
Tim Peterse3547fd2005-12-16 23:13:57 +00001234- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001235 flags on the HTTP listening socket.
1236
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001237- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1238 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1239
Tim Peterse3547fd2005-12-16 23:13:57 +00001240- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001241 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1242
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001243- Bug #1110478: Revert os.environ.update to do putenv again.
1244
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001245- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1246
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001247- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1248
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001249- Enhancements to the csv module:
1250
1251 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001252 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001253 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001254 + Dialect parameter parsing has been re-implemented to improve error
1255 reporting.
1256 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1257 dictates.
1258 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001259 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001260 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001261 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1262 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001263 + reader now allows \r characters to be quoted (previously it only allowed
1264 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001265 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001266 + Dialect classes passed to the module are no longer instantiated by
1267 the module before being parsed (the former validation scheme required
1268 this, but the mechanism was unreliable).
1269 + The dialect registry now contains instances of the internal
1270 C-coded dialect type, rather than references to python objects.
1271 + the internal c-coded dialect type is now immutable.
1272 + register_dialect now accepts the same keyword dialect specifications
1273 as the reader and writer, allowing the user to register dialects
1274 without first creating a dialect class.
1275 + a configurable limit to the size of parsed fields has been added -
1276 previously, an unmatched quote character could result in the entire
1277 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001278 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001279 the parser field size limit (returning the former limit). The initial
1280 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001281 + A line_num attribute has been added to the reader object, which tracks
1282 the number of lines read from the source iterator. This is not
1283 the same as the number of records returned, as records can span
1284 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001285 + reader and writer objects were not being registered with the cyclic-GC.
1286 This has been fixed.
1287
Brett Cannone6539c42005-01-08 02:43:53 +00001288- _DummyThread objects in the threading module now delete self.__block that is
1289 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1290 lock primitives tend to be limited in number and thus should not be wasted on
1291 a _DummyThread object. Fixes bug #1089632.
1292
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001293- The imghdr module now detects Exif files.
1294
Raymond Hettinger6065d322004-12-20 23:51:53 +00001295- StringIO.truncate() now correctly adjusts the size attribute.
1296 (Bug #951915).
1297
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001298- locale.py now uses an updated locale alias table (built using
1299 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1300 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001301 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001302
Raymond Hettinger3557f422004-12-07 12:02:02 +00001303- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1304
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001305- the pickle module no longer accepts the deprecated None option in the
1306 args tuple returned by __reduce__().
1307
Brett Cannon84667c02004-12-07 03:25:18 +00001308- optparse now optionally imports gettext. This allows its use in setup.py.
1309
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001310- the pickle module no longer uses the deprecated bin parameter.
1311
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001312- the shelve module no longer uses the deprecated binary parameter.
1313
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001314- the pstats module no longer uses the deprecated ignore() method.
1315
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001316- the filecmp module no longer uses the deprecated use_statcache argument.
1317
Raymond Hettinger664347b2004-12-04 21:21:53 +00001318- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1319 extended or overridden by subclasses. Formerly, the subclassed method would
1320 be ignored by the rest of the module. (Bug #1078905).
1321
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001322- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001323 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001324
Walter Dörwald36733692004-12-22 12:50:50 +00001325- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1326 once when a size argument is given. This prevents a buffer overflow in the
1327 tokenizer with very long source lines.
1328
Barry Warsaw538561e2006-01-01 21:48:54 +00001329- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1330 immediately after creating the object, without any intervening
1331 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001332
Skip Montanaro05885812005-01-16 20:48:27 +00001333- The reconvert.quote function can now emit triple-quoted strings. The
1334 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001335
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001336- ``UserString.MutableString`` now supports negative indices in
1337 ``__setitem__`` and ``__delitem__``
1338
Greg Ward40407942005-03-05 02:53:17 +00001339- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1340 correctly.
1341
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001342- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1343 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1344 character even if the user has passed a size parameter to get a proper
1345 line ending. Remove the special handling of a "\r\n" that has been split
1346 between two lines.
1347
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001348- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1349 about illegal code points. The codec now supports PEP 293 style error
1350 handlers.
1351
Walter Dörwald78a78b02005-09-01 12:04:29 +00001352- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001353 from the input stream, so that the output is a byte string in the correct
1354 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001355
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001356- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1357 considering it exactly like a '*'.
1358
Walter Dörwald007f8df2005-10-09 19:42:27 +00001359- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1360 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001361
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001362- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1363
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001364- Patch #1413711: Certain patterns of differences were making difflib
1365 touch the recursion limit.
1366
Walter Dörwald58917a62006-03-31 15:26:22 +00001367- Bug #947906: An object oriented interface has been added to the calendar
1368 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001369 called as a script (e.g. via ``python -mcalendar``). Localized month and
1370 weekday names can be ouput (even if an exotic encoding is used) using
1371 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001372

1388 The zlib module is now builtin on Windows.
1389
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001390- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1391
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001392- Bug #1189330: configure did not correctly determine the necessary
1393 value of LINKCC if python was built with GCC 4.0.
1394
Trent Mick8321b422005-07-26 02:29:21 +00001395- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1396 vulnerability in zlib 1.2.1 and 1.2.2.
1397
Brett Cannon08cd5982005-04-24 22:26:38 +00001398- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1399 flags that change binary compatibility. Changes were also made to
1400 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001401 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001402
Bob Ippolitoed233462005-03-29 13:47:59 +00001403- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1404 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1405 no longer exists). This configure patch makes things right.
1406
Martin v. Löwise2713be2005-03-08 15:03:08 +00001407- Bug #1158607: Build with --disable-unicode again.
1408
Brett Cannon46d96232005-02-16 00:07:19 +00001409- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1410 defined. Discovered as a result of not being able to build on OS X.
1411
Brett Cannon516592f2004-12-07 00:42:59 +00001412- setup.py now uses the directories specified in LDFLAGS using the -L option
1413 and in CPPFLAGS using the -I option for adding library and include
1414 directories, respectively, for compiling extension modules against. This has
1415 led to the core being compiled using the values in CPPFLAGS. It also removes
1416 the need for the special-casing of both DarwinPorts and Fink for darwin since
1417 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1418 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1419 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00001421- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1422 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1423 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1424 Closes bug #1096244. Thanks Gregory Bond.

1428
Tim Petersc9d78aa2006-03-26 23:27:58 +00001429- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1430 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1431 is obtained via the ``PyObject_`` family, it must be released via the
1432 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1433 always been officially true, but when Python's small-object allocator was
1434 introduced, an attempt was made to cater to a few extension modules
1435 discovered at the time that obtained memory via ``PyObject_New`` but
1436 released it via ``PyMem_DEL``. It's years later, and if such code still
1437 exists it will fail now (probably with segfaults, but calling wrong
1438 low-level memory management functions can yield many symptoms).
1439
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001440- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001444- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1445 mapping argument now. This string is used as a mapping table. Byte values
1446 greater than the length of the string and 0xFFFE are treated as undefined
1447 mappings.
