35 is created.
36
Martin v. Löwis7596e832006-07-01 15:33:37 +000037- Bug #1513223: .close() of a _socketobj now releases the underlying
38 socket again, which then gets closed as it becomes unreferenced.
39
Thomas Hellerbde08132006-06-29 18:34:15 +000040- The '_ctypes' extension module now works when Python is configured
41 with the --without-threads option.

50
Brett Cannon53ab5b72006-06-22 16:49:14 +000051- Bug #1510580: The 'warnings' module improperly required that a Warning
52 category be either a types.ClassType and a subclass of Warning. The proper
53 check is just that it is a subclass with Warning as the documentation states.
54
Georg Brandlad29e632006-06-21 17:45:17 +000055- The compiler module now correctly compiles the new try-except-finally

99Core and builtins
100-----------------
101
Georg Brandla56b9152006-06-19 06:35:54 +0000102- Patch #1507676: Error messages returned by invalid abstract object operations
103 (such as iterating over an integer) have been improved and now include the
104 type of the offending object to help with debugging.
105
Brett Cannonea3912b2006-06-13 21:46:41 +0000106- Bug #992017: A classic class that defined a __coerce__() method that returned
107 its arguments swapped would infinitely recurse and segfault the interpreter.
108
Neal Norwitz909eb122006-06-12 02:13:21 +0000109- Fix the socket tests so they can be run concurrently.
110
Neal Norwitzb9845e72006-06-12 02:11:18 +0000111- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000112 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000113
Brett Cannon22565aa2006-06-09 22:31:23 +0000114- Bug #532646: object.__call__() will continue looking for the __call__
115 attribute on objects until one without one is found. This leads to recursion
116 when you take a class and set its __call__ attribute to an instance of the
117 class. Originally fixed for classic classes, but this fix is for new-style.
118 Removes the infinite_rec_3 crasher.
119
Georg Brandl24250812006-06-09 18:45:48 +0000120- The string and unicode methods startswith() and endswith() now accept
121 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
122
Brett Cannonde3b0522006-06-08 17:00:45 +0000123- Buffer objects, at the C level, never used the char buffer
124 implementation even when the char buffer for the wrapped object was
125 explicitly requested (originally returned the read or write buffer).
126 Now a TypeError is raised if the char buffer is not present but is
127 requested.
128
Georg Brandlddbaa662006-06-04 21:56:52 +0000129- Patch #1346214: Statements like "if 0: suite" are now again optimized
130 away like they were in Python 2.4.
131
Georg Brandlb7c8f542006-05-27 12:30:25 +0000132- Builtin exceptions are now full-blown new-style classes instead of
133 instances pretending to be classes, which speeds up exception handling
134 by about 80% in comparison to 2.5a2.
135
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000136- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
137 Unicode 4.1.
138
Georg Brandlf4ef1162006-05-26 18:03:31 +0000139- Patch #921466: sys.path_importer_cache is now used to cache valid and
140 invalid file paths for the built-in import machinery which leads to
141 fewer open calls on startup.
142
Tim Peters696cf432006-05-24 21:10:40 +0000143- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
144 of-2 bases. The largest speedup is for inputs with about 1000 decimal
145 digits. Conversion from non-power-of-2 bases remains quadratic-time in
146 the number of input digits (it was and remains linear-time for bases
147 2, 4, 8, 16 and 32).
148
Tim Petersb713ec22006-05-23 18:45:30 +0000149- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
150 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
151 an integer close to ``sys.maxint``. This was repaired by patch
152 #1335972, which also gives a nice speedup.
153
Richard Jonescebbefc2006-05-23 18:28:17 +0000154- Patch #1337051: reduced size of frame objects.
155
156- PyErr_NewException now accepts a tuple of base classes as its
157 "base" parameter.
158
Richard Jones7c88dcc2006-05-23 10:37:38 +0000159- Patch #876206: function call speedup by retaining allocated frame
160 objects.
161
Georg Brandl7b90e162006-05-18 07:01:27 +0000162- Bug #1462152: file() now checks more thoroughly for invalid mode
163 strings and removes a possible "U" before passing the mode to the
164 C library function.
165
Neal Norwitz1004a532006-05-15 07:17:23 +0000166- Patch #1488312, Fix memory alignment problem on SPARC in unicode
167
Neal Norwitz373f0a72006-05-15 07:04:36 +0000168- Bug #1487966: Fix SystemError with conditional expression in assignment
169
Martin v. Löwis879768d2006-05-11 13:28:43 +0000170- WindowsError now has two error code attributes: errno, which carries
171 the error values from errno.h, and winerror, which carries the error
172 values from winerror.h. Previous versions put the winerror.h values
173 (from GetLastError()) into the errno attribute.
174
Martin v. Löwis77736712006-05-04 05:51:03 +0000175- Patch #1475845: Raise IndentationError for unexpected indent.
176
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000177- Patch #1479181: split open() and file() from being aliases for each other.
178
Tim Peters44bd9862006-06-01 13:49:23 +0000179- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
180 methods were always silently ignored by dictionaries when comparing keys.
181 They are now passed through (except when using the C API function
182 ``PyDict_GetItem()``, whose semantics did not change).
183
184- Bug #1456209: In some obscure cases it was possible for a class with a
185 custom ``__eq__()`` method to confuse dict internals when class instances
186 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
187 No, you don't have any code that did this ;-)

195
Brett Cannon6ee7d012006-06-08 16:23:04 +0000196- Change binascii.hexlify to accept a read-only buffer instead of only a char
197 buffer and actually follow its documentation.
198

200
Nick Coghlanc649ec52006-05-29 12:43:05 +0000201- Patch #1478788 (modified version): The functional extension module has
202 been renamed to _functools and a functools Python wrapper module added.
203 This provides a home for additional function related utilities that are
204 not specifically about functional programming. See PEP 309.
205
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000206- Patch #1493701: performance enhancements for struct module.

214 enabled builds on Windows and systems with Posix threads support.
215
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000216- On Win32, os.listdir now supports arbitrarily-long Unicode path names
217 (up to the system limit of 32K characters).
218
219- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
220 As a result, these functions now raise WindowsError instead of OSError.
221
Tim Peters7a822da2006-05-25 21:50:17 +0000222- ``time.clock()`` on Win64 should use the high-performance Windows
223 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
224 Windows platforms).
225
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000226- Calling Tk_Init twice is refused if the first call failed as that
227 may deadlock.
228
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000229- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
230 accept it without potentially using an uninitialized pointer.
231
232- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
233 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

238
Gregory P. Smith372b5832006-06-05 18:48:21 +0000239- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
240 parameter is supplied. [SF pybsddb bug #1477863]
241
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000242- bsddb: the __len__ method of a DB object has been fixed to return correct
243 results. It could previously incorrectly return 0 in some cases.
244 Fixes SF bug 1493322 (pybsddb bug 1184012).
245
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000246- bsddb: the bsddb.dbtables Modify method now raises the proper error and
247 aborts the db transaction safely when a modifier callback fails.
248 Fixes SF python patch/bug #1408584.
249
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000250- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000251 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000252 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
253 database calls that would previously deadlock. [SF python bug #775414]
254

284
Tim Peters43898b42006-06-14 04:09:25 +0000285- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
286 guarantee that adjacent triples in the return list always describe
287 non-adjacent blocks. Previously, a pair of matching blocks could end
288 up being described by multiple adjacent triples that formed a partition
289 of the matching pair.

Tim Petersd609b1a2006-06-02 23:22:51 +0000311- The functions in the ``pprint`` module now sort dictionaries by key
312 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
313 if and only if its display required more than one line, although that
314 wasn't documented. The new behavior increases predictability; e.g.,
315 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
316
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000317- Patch #1497027: try HTTP digest auth before basic auth in urllib2
318 (thanks for J. J. Lee).
319
Georg Brandl2b330372006-05-28 20:23:12 +0000320- Patch #1496206: improve urllib2 handling of passwords with respect to
321 default HTTP and HTTPS ports.
322
George Yoshidaf3c65de2006-05-28 16:39:09 +0000323- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
324
Bob Ippolito7298f272006-05-23 18:43:47 +0000325- Patch #1281707: speed up gzip.readline.
326
Georg Brandlb89316f2006-05-17 15:51:16 +0000327- Patch #1180296: Two new functions were added to the locale module:
328 format_string() to get the effect of "format % items" but locale-aware,
329 and currency() to format a monetary number with currency sign.
330
Georg Brandle3a25832006-05-17 14:56:04 +0000331- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
332 and several features added, such as speed and geometry control.
333
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000334- Patch #1488881: add support for external file objects in bz2 compressed
335 tarfiles.
336
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000337- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
338 stdout arguments, making it possible to redirect input and output
339 for remote debugging.
340
341- Patch #1484695: Update the tarfile module to version 0.8. This fixes
342 a couple of issues, notably handling of long file names using the
343 GNU LONGNAME extension.
344
345- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
346 new flag when ``name`` is already the name of an option flag.
347
348- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
349 package.
350
351- Patch #1472854: make the rlcompleter.Completer class usable on non-
352 UNIX platforms.
353
354- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
355
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000356- Bug #1472827: correctly escape newlines and tabs in attribute values in
357 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000387What's New in Python 2.5 alpha 2?
388=================================
389
390*Release date: 27-APR-2006*
391
392Core and builtins
393-----------------
394
Thomas Heller1b046642006-04-18 18:51:06 +0000395- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
396 by converting these apis from macros into exported functions again:
397
398 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
399 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
400 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
401 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
402 PyRun_String Py_CompileString
403
Martin v. Löwis45294a92006-04-18 06:24:08 +0000404- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
405
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000406- All uses of PyStructSequence_InitType have been changed to initialize
407 the type objects only once, even if the interpreter is initialized
408 multiple times.
409
Neal Norwitz61546162006-04-14 05:20:28 +0000410- Bug #1454485, array.array('u') could crash the interpreter. This was
411 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
412 to unicode when it didn't make sense. 'u#' now requires a unicode string.
413
414- Py_UNICODE is unsigned. It was always documented as unsigned, but
415 due to a bug had a signed value in previous versions.
416
Tim Peters3a5e8b12006-04-11 01:44:07 +0000417- Patch #837242: ``id()`` of any Python object always gives a positive
418 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
419 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000420 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000421 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000422
Tim Peters3a5e8b12006-04-11 01:44:07 +0000423 def __hash__(self):
424 return id(self) # WRONG
425
426 because a hash result must be a (short) Python int but it was always
427 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000428 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000429 was always usable as a hash value before this patch. That's no longer
430 necessarily so.
431
432- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000433 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000434 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000435 #1454844)
436
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000437- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
438 involving generators that have paused outside of any ``try`` or ``with``
439 blocks. (In 2.5a1, a paused generator that was part of a reference
440 cycle could not be garbage collected, regardless of whether it was
441 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000443Extension Modules

447 is a macro.
448
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000449- Bug #1467952: os.listdir() now correctly raises an error if readdir()
450 fails with an error condition.
451
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000452- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
453
454- Bug #1117761: bsddb.*open() no longer raises an exception when using
455 the cachesize parameter.
456
457- Bug #1149413: bsddb.*open() no longer raises an exception when using
458 a temporary db (file=None) with the 'n' flag to truncate on open.
459
460- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
461 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000462
Armin Rigoa9017c32006-04-19 11:50:27 +0000463- Patch #1062014: AF_UNIX sockets under Linux have a special
464 abstract namespace that is now fully supported.
465
Anthony Baxter51bcb682006-04-05 14:51:42 +0000466Library
467-------
468
Tim Peters711bf302006-04-25 03:31:36 +0000469- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
470 a doctest to be skipped (the code is not run, and the expected output
471 or exception is ignored).
472
Nick Coghlanda2268f2006-04-24 04:37:15 +0000473- Fixed contextlib.nested to cope with exceptions being raised and
474 caught inside exit handlers.
475
Greg Wardab05edc2006-04-23 03:47:58 +0000476- Updated optparse module to Optik 1.5.1 (allow numeric constants in
477 hex, octal, or binary; add ``append_const`` action; keep going if
478 gettext cannot be imported; added ``OptionParser.destroy()`` method;
479 added ``epilog`` for better help generation).
480
Tim Peters21fbd572006-04-21 21:18:10 +0000481- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
482 called from a thread spawned as a side effect of importing a module.
483
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000484- The pydoc module now supports documenting packages contained in
485 .zip or .egg files.
486
487- The pkgutil module now has several new utility functions, such
488 as ``walk_packages()`` to support working with packages that are either
489 in the filesystem or zip files.
490
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000491- The mailbox module can now modify and delete messages from
492 mailboxes, in addition to simply reading them. Thanks to Gregory
493 K. Johnson for writing the code, and to the 2005 Google Summer of
494 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000495
Tim Petersc7605f22006-04-17 21:12:33 +0000496- The ``__del__`` method of class ``local`` in module ``_threading_local``
497 returned before accomplishing any of its intended cleanup.
498
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000499- Patch #790710: Add breakpoint command lists in pdb.
500
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000501- Patch #1063914: Add Tkinter.Misc.clipboard_get().
502
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000503- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
504
Anthony Baxtere29002c2006-04-12 12:07:31 +0000505- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
506 Windows. Bug #1469163.
507
Phillip J. Eby47032112006-04-11 01:07:43 +0000508- The warnings, linecache, inspect, traceback, site, and doctest modules
509 were updated to work correctly with modules imported from zipfiles or
510 via other PEP 302 __loader__ objects.
511
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000512- Patch #1467770: Reduce usage of subprocess._active to processes which
513 the application hasn't waited on.
514
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000515- Patch #1462222: Fix Tix.Grid.
516
Neal Norwitza31bf182006-04-09 03:35:43 +0000517- Fix exception when doing glob.glob('anything*/')
518
Skip Montanaro262fb922006-04-21 02:31:07 +0000519- The pstats.Stats class accepts an optional stream keyword argument to
520 direct output to an alternate file-like object.
521
Anthony Baxter51bcb682006-04-05 14:51:42 +0000522Build
523-----
524
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000525- The Makefile now has a reindent target, which runs reindent.py on
526 the library.
527
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000528- Patch #1470875: Building Python with MS Free Compiler
529
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000530- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000531
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000532- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
533 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000534 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000535 CXX from --with-cxx-main, see description in README.
536
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000537- Patch #1429775: Link extension modules with the shared libpython.
538
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000539- Fixed a libffi build problem on MIPS systems.
540
Tim Peters8931ff12006-05-13 23:28:20 +0000541- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
542 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
543 and "%zu" for unsigned integers of type ``size_t``.
544
Anthony Baxter51bcb682006-04-05 14:51:42 +0000545Tests
546-----
547
Nick Coghlanda2268f2006-04-24 04:37:15 +0000548- test_contextlib now checks contextlib.nested can cope with exceptions
549 being raised and caught inside exit handlers.
550
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000551- test_cmd_line now checks operation of the -m and -c command switches
552
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000553- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
554 it separately and by hand. It also wasn't cleaning up its changes to
555 the current Decimal context.
556
Thomas Woutersabd08882006-04-26 15:53:30 +0000557- regrtest.py now has a -M option to run tests that test the new limits of
558 containers, on 64-bit architectures. Running these tests is only sensible
559 on 64-bit machines with more than two gigabytes of memory. The argument
560 passed is the maximum amount of memory for the tests to use.

569-------------
570
Tim Petersb06d28c2006-05-12 01:57:59 +0000571- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
572
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000573- PEP 343: Added Context Types section to the library reference
574 and attempted to bring other PEP 343 related documentation into
575 line with the implementation and/or python-dev discussions.
576
Tim Peters8dc73d22006-04-24 02:03:16 +0000577- Bug #1337990: clarified that ``doctest`` does not support examples
578 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000581What's New in Python 2.5 alpha 1?
582=================================
583
Anthony Baxterebed3f62006-04-03 15:03:44 +0000584*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000585
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000586Core and builtins
587-----------------
588
Nick Coghlan43832302006-04-23 17:04:07 +0000589- PEP 338: -m command line switch now delegates to runpy.run_module
590 allowing it to support modules in packages and zipfiles
591
Martin v. Löwisc661b882006-04-20 04:54:23 +0000592- On Windows, .DLL is not an accepted file name extension for
593 extension modules anymore; extensions are only found if they
594 end in .PYD.
595
Martin v. Löwisea62d252006-04-03 10:56:49 +0000596- Bug #1421664: sys.stderr.encoding is now set to the same value as
597 sys.stdout.encoding.
598
Neal Norwitz92e212f2006-04-03 04:48:37 +0000599- __import__ accepts keyword arguments.
600
Georg Brandlccadf842006-03-31 18:54:53 +0000601- Patch #1460496: round() now accepts keyword arguments.
602
Anthony Baxter262c00a2006-03-30 10:53:17 +0000603- Fixed bug #1459029 - unicode reprs were double-escaped.
604
Hye-Shik Changd478f342006-03-23 12:32:36 +0000605- Patch #1396919: The system scope threads are reenabled on FreeBSD
606 5.4 and later versions.
607
Neal Norwitze98ccf62006-03-23 05:39:47 +0000608- Bug #1115379: Compiling a Unicode string with an encoding declaration
609 now gives a SyntaxError.
610
Georg Brandlabd1ff82006-03-18 07:59:59 +0000611- Previously, Python code had no easy way to access the contents of a
612 cell object. Now, a ``cell_contents`` attribute has been added
613 (closes patch #1170323).
614
Tim Peterscf79aac2006-03-16 01:14:46 +0000615- Patch #1123430: Python's small-object allocator now returns an arena to
616 the system ``free()`` when all memory within an arena becomes unused
617 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
618 freed. Some applications will see a drop in virtual memory size now,
619 especially long-running applications that, from time to time, temporarily
620 use a large number of small objects. Note that when Python returns an
621 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000622 platform C library will in turn return that memory to the operating system.
623 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000624 appears to be effective at least on Microsoft C and gcc-based systems.
625 Thanks to Evan Jones for hard work and patience.
626
Georg Brandl533ff6f2006-03-08 18:09:27 +0000627- Patch #1434038: property() now uses the getter's docstring if there is
628 no "doc" argument given. This makes it possible to legitimately use
629 property() as a decorator to produce a read-only property.
630
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000631- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
632 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
633 of requiring an int or long in slicing and a few other contexts, enabling
634 other objects (e.g. Numeric Python's integers) to be used as slice indices.
635
Neal Norwitz995acdf2006-03-07 05:01:00 +0000636- Fixed various bugs reported by Coverity's Prevent tool.
637
Brett Cannonbf364092006-03-01 04:25:17 +0000638- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
639 new exception base class, BaseException, which has a new message attribute.
640 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
641 Raising a string exception now raises a DeprecationWarning.
642
Thomas Woutersfb609f42006-02-28 16:37:25 +0000643- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
644 explicitly relative, using 'from .module import name' to mean 'from the same
645 package as this module is in. Imports without dots still default to the
646 old relative-then-absolute, unless 'from __future__ import
647 absolute_import' is used.
648
Brett Cannona7446e32006-02-27 23:39:10 +0000649- Properly check if 'warnings' raises an exception (usually when a filter set
650 to "error" is triggered) when raising a warning for raising string
651 exceptions.
652
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000653- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000654 The name was removed from Include/code.h.
655
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000656- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000657
Guido van Rossum1968ad32006-02-25 22:38:04 +0000658- Patch 1433928:
659 - The copy module now "copies" function objects (as atomic objects).
660 - dict.__getitem__ now looks for a __missing__ hook before raising
661 KeyError.
662
Tim Peters84ef21c2006-02-28 20:39:06 +0000663- PEP 343: with statement implemented. Needs ``from __future__ import
664 with_statement``. Use of 'with' as a variable will generate a warning.
665 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000666 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000667 The following objects have __context__ methods:
668 - The built-in file type.
669 - The thread.LockType type.
670 - The following types defined by the threading module:
671 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
672 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000673
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000674- Fix the encodings package codec search function to only search
675 inside its own package. Fixes problem reported in patch #1433198.
676
677 Note: Codec packages should implement and register their own
678 codec search function. PEP 100 has the details.
679
Tim Peters9ea89d22006-06-04 03:26:02 +0000680- PEP 353: Using ``Py_ssize_t`` as the index type.
681
682- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
683 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
684 now allow Python to make use of memory blocks exceeding 2**32 bytes for
685 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
686 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000687
Neal Norwitzfc76d632006-01-10 06:03:13 +0000688- Patch #1400181, fix unicode string formatting to not use the locale.
689 This is how string objects work. u'%f' could use , instead of .
690 for the decimal point. Now both strings and unicode always use periods.
691
Neal Norwitz671b9e32006-01-09 07:07:12 +0000692- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
693 configure would break checking curses.h.
694
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000695- Bug #959576: The pwd module is now builtin. This allows Python to be
696 built on UNIX platforms without $HOME set.
697
Neal Norwitzc10978f2005-12-19 06:07:16 +0000698- Bug #1072182, fix some potential problems if characters are signed.
699
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000700- Bug #889500, fix line number on SyntaxWarning for global declarations.
701
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000702- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
703
Neal Norwitze7214a12005-12-18 05:03:17 +0000704- Support for converting hex strings to floats no longer works.
705 This was not portable. float('0x3') now raises a ValueError.
706
Barry Warsaw2a38a862005-12-18 01:27:35 +0000707- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000708 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000709 is now displayed in interactive prompt banner.
710
Georg Brandlfa166682005-12-17 21:45:17 +0000711- Implementation of PEP 341 - Unification of try/except and try/finally.
712 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000713 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000714
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000715- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
716 now encodes backslash correctly.
717
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000718- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
719
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000720- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000721 and long longs.
722
Neal Norwitz67715f02005-11-09 06:59:35 +0000723- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000724 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000725 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000726
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000727- Replaced most Unicode charmap codecs with new ones using the
728 new Unicode translate string feature in the builtin charmap
729 codec; the codecs were created from the mapping tables available
730 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
731 encodings now include a mapping for the Apple logo)
732
Tim Peterse3547fd2005-12-16 23:13:57 +0000733- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000734
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000735- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000736
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000737- A new AST parser implementation was completed. The abstract
738 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000739 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000740
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000741- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000742 The following code now raises a SyntaxError: foo(a = i for i in range(10))
743
Neal Norwitz708e51a2005-10-03 04:48:15 +0000744- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
745
Neal Norwitz11bd1192005-10-03 00:54:56 +0000746- SF Bug #887946: fix segfault when redirecting stdin from a directory.
747 Provide a warning when a directory is passed on the command line.
748
Neal Norwitz40d37812005-10-02 01:48:49 +0000749- Fix segfault with invalid coding.
750
751- SF bug #772896: unknown encoding results in MemoryError.
752
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000753- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000754 supported a __len__() method which evaluated to False when the iterator
755 was empty.
756
Guido van Rossum630db602005-09-20 18:49:54 +0000757- On 64-bit platforms, when __len__() returns a value that cannot be
758 represented as a C int, raise OverflowError.
759
Skip Montanarof8948ca2005-09-19 03:54:46 +0000760- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000761 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000762
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000763- SF bug #893549: parsing keyword arguments was broken with a few format
764 codes.
765
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000766- Changes donated by Elemental Security to make it work on AIX 5.3
767 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
768 bug #105470: test_pwd fails on 64bit system (Opteron).
769
Guido van Rossum539c6622005-09-14 17:49:54 +0000770- Changes donated by Elemental Security to make it work on HP-UX 11 on
771 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
772
Georg Brandl4550b8d2005-08-26 06:43:52 +0000773- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000774 (fixes bug #1119418).
775
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000776- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
777
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000778- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
779 exceptions that cause a function to exit.
780
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000781- The implementation of set() and frozenset() was revised to use its
782 own internal data structure. Memory consumption is reduced by 1/3
783 and there are modest speed-ups as well. The API is unchanged.
784
Tim Petersde7990b2005-07-17 23:45:23 +0000785- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
786
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000787- SF bug #1229429: PyObject_CallMethod failed to decrement some
788 reference counts in some error exit cases.
789
Tim Petersecc6e6a2005-07-10 22:30:55 +0000790- SF bug #1185883: Python's small-object memory allocator took over
791 a block managed by the platform C library whenever a realloc specified
792 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000793 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000794 portable way to copy data from the C-managed block into Python's
795 small-object space without risking a memory fault. Python's small-object
796 realloc now leaves such blocks under the control of the platform C
797 realloc.
798
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000799- SF bug #1232517: An overflow error was not detected properly when
800 attempting to convert a large float to an int in os.utime().
801
Raymond Hettinger3296e692005-06-29 23:29:56 +0000802- SF bug #1224347: hex longs now print with lowercase letters just
803 like their int counterparts.
804
Michael W. Hudson188d4362005-06-20 16:52:57 +0000805- SF bug #1163563: the original fix for bug #1010677 ("thread Module
806 Breaks PyGILState_Ensure()") broke badly in the case of multiple
807 interpreter states; back out that fix and do a better job (see
808 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
809 for a longer write-up of the problem).
810
Michael W. Hudsondf888462005-06-03 14:41:55 +0000811- SF patch #1180995: marshal now uses a binary format by default when
812 serializing floats.
813
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000814- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
815 the routines that promise to produce IEEE 754 binary representations
816 of floats now simply copy bytes around.
817
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000818- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
819 278.
820
Brett Cannonc3647ac2005-04-26 03:45:26 +0000821- patch #1109424: int, long, float, complex, and unicode now check for the
822 proper magic slot for type conversions when subclassed. Previously the
823 magic slot was ignored during conversion. Semantics now match the way
824 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000825 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000826 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000827 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000828
Barry Warsawc8d907c2005-04-19 23:43:40 +0000829- Descriptors defined in C with a PyGetSetDef structure, where the setter is
830 NULL, now raise an AttributeError when attempting to set or delete the
831 attribute. Previously a TypeError was raised, but this was inconsistent
832 with the equivalent pure-Python implementation.
833
Michael W. Hudson774479c2005-04-18 08:46:17 +0000834- It is now safe to call PyGILState_Release() before
835 PyEval_InitThreads() (note that if there is reason to believe there
836 are multiple threads around you still must call PyEval_InitThreads()
837 before using the Python API; this fix is for extension modules that
838 have no way of knowing if Python is multi-threaded yet).
839
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000840- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
841 disabled caused a crash.
842
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000843- Bug #1165306: instancemethod_new allowed the creation of a method
844 with im_class == im_self == NULL, which caused a crash when called.
845
Tim Petersecc6e6a2005-07-10 22:30:55 +0000846- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000847 fixes the crash seen in bug #1165761
848
Raymond Hettinger96229b12005-03-11 06:49:40 +0000849- Added two new builtins, any() and all().
850
Brett Cannon409d8f22005-03-05 06:47:57 +0000851- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000852 (e.g., ``class C(): pass`` is no longer a syntax error).
853 Patch #1176012 added support to the 'parser' module and 'compiler' package
854 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000855
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000856- Patch #1115086: Support PY_LONGLONG in structmember.
857
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000858- Bug #1155938: new style classes did not check that __init__() was
859 returning None.
860
Tim Petersecc6e6a2005-07-10 22:30:55 +0000861- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000862 ('\') with a specific error message.
863
Martin v. Löwisff232d72005-03-03 09:24:38 +0000864- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
865
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000866- Bug #1124295: the __name__ attribute of file objects was
867 inadvertently made inaccessible in restricted mode.
868
Tim Petersecc6e6a2005-07-10 22:30:55 +0000869- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000870 an ferror() call.
871
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000872- min() and max() now support key= arguments with the same meaning as in
873 list.sort().
874
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000875- The peephole optimizer now performs simple constant folding in expressions:
876 (2+3) --> (5).
877
Raymond Hettingera422c342005-01-11 03:03:27 +0000878- set and frozenset objects can now be marshalled. SF #1098985.
879
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000880- Bug #1077106: Poor argument checking could cause memory corruption
881 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000882
Jeremy Hyltonab630502005-02-04 18:44:06 +0000883- The parser did not complain about future statements in illegal
884 positions. It once again reports a syntax error if a future
885 statement occurs after anything other than a doc string.
886
Neil Schemenauercf52c072005-08-12 17:34:58 +0000887- Change the %s format specifier for str objects so that it returns a
888 unicode instance if the argument is not an instance of basestring and
889 calling __str__ on the argument returns a unicode instance.
890
Tim Petersf4e69282006-02-27 17:15:31 +0000891- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
892 current thread state when the auto-GIL-state machinery knows about
893 it (since the thread state is being deleted, continuing to remember it
894 can't help, but can hurt if another thread happens to get created with
895 the same thread id).
896
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000897Extension Modules
898-----------------
899
Georg Brandl43f08a82006-03-31 18:01:16 +0000900- Patch #1380952: fix SSL objects timing out on consecutive read()s
901
Neal Norwitz05a45592006-03-20 06:30:08 +0000902- Patch #1309579: wait3 and wait4 were added to the posix module.
903
Anthony Baxterfa869072006-03-20 05:21:58 +0000904- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

1085-------
1086
Nick Coghlan43832302006-04-23 17:04:07 +00001087- PEP 338: new module runpy defines a run_module function to support
1088 executing modules which provide access to source code or a code object
1089 via the PEP 302 import mechanisms.
1090
Anthony Baxter93f5b932006-04-03 08:05:07 +00001091- The email module's parsedate_tz function now sets the daylight savings

1099 in attribute values.
1100
Anthony Baxterc51ee692006-04-01 00:57:31 +00001101- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001102 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001103 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001104 module will not be built.
1105
Tim Petersc17976e2006-04-01 00:26:53 +00001106- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1107 aren't officially supported here, and trying to use them will probably
1108 raise an exception some day. But dicts have been allowed, and "mostly
1109 worked", so support for them won't go away without warning.
1110
Georg Brandl338ef7d2006-03-31 18:42:16 +00001111- Bug #1445068: getpass.getpass() can now be given an explicit stream
1112 argument to specify where to write the prompt.
1113

1129
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001130- email 4.0 package now integrated. This is largely the same as the email 3.0
1131 package that was included in Python 2.3, except that PEP 8 module names are
1132 now used (e.g. mail.message instead of email.Message). The MIME classes
1133 have been moved to a subpackage (e.g. email.mime.text instead of
1134 email.MIMEText). The old names are still supported for now. Several
1135 deprecated Message methods have been removed and lots of bugs have been
1136 fixed. More details can be found in the email package documentation.
1137
Walter Dörwald40108c92006-03-27 08:15:44 +00001138- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1139 (a subclass of tuple) that provides incremental decoders and encoders
1140 (a way to use stateful codecs without the stream API). Python functions
1141 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1142 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1143 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001144
Walter Dörwald067db482006-03-15 22:17:27 +00001145- Patch #1359365: Calling next() on a closed StringIO.String object raises
1146 a ValueError instead of a StopIteration now (like file and cString.String do).
1147 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1148 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001149
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001150- A regrtest option -w was added to re-run failed tests in verbose mode.

1218 LoadError as documented, instead of IOError. For compatibility,
1219 LoadError subclasses IOError.
1220
Brett Cannon3cbd0382005-12-16 22:49:23 +00001221- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001222 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1223 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1224 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1225 Ronald L. Rivest offered this advice for Python:
1226
1227 "The consensus of researchers in this area (at least as
1228 expressed at the NIST Hash Function Workshop 10/31/05),
1229 is that SHA-256 is a good choice for the time being, but
1230 that research should continue, and other alternatives may
1231 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001232
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001233- Added a subset of Fredrik Lundh's ElementTree package. Available

1286 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001287 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001288

1327
Raymond Hettinger68c04532005-06-10 11:05:19 +00001328- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001329 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001330 the generate_tokens() function now accepts a callable argument that

1352 work as expected.
1353
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001354- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001392- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1393 disables recursive traversal through instance attributes, which can
1394 be exploited in various ways.
1395
Tim Peterse3547fd2005-12-16 23:13:57 +00001396- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

1410
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001411- Enhancements to the csv module:
1412
1413 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001414 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001415 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001416 + Dialect parameter parsing has been re-implemented to improve error
1417 reporting.
1418 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1419 dictates.
1420 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001421 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001422 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001423 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1424 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001425 + reader now allows \r characters to be quoted (previously it only allowed
1426 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001427 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001428 + Dialect classes passed to the module are no longer instantiated by
1429 the module before being parsed (the former validation scheme required
1430 this, but the mechanism was unreliable).
1431 + The dialect registry now contains instances of the internal
1432 C-coded dialect type, rather than references to python objects.
1433 + the internal c-coded dialect type is now immutable.
1434 + register_dialect now accepts the same keyword dialect specifications
1435 as the reader and writer, allowing the user to register dialects
1436 without first creating a dialect class.
1437 + a configurable limit to the size of parsed fields has been added -
1438 previously, an unmatched quote character could result in the entire
1439 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001440 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001441 the parser field size limit (returning the former limit). The initial
1442 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001443 + A line_num attribute has been added to the reader object, which tracks
1444 the number of lines read from the source iterator. This is not
1445 the same as the number of records returned, as records can span
1446 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001447 + reader and writer objects were not being registered with the cyclic-GC.
1448 This has been fixed.
1449
Brett Cannone6539c42005-01-08 02:43:53 +00001450- _DummyThread objects in the threading module now delete self.__block that is
1451 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1452 lock primitives tend to be limited in number and thus should not be wasted on
1453 a _DummyThread object. Fixes bug #1089632.
1454
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001455- The imghdr module now detects Exif files.
1456
Raymond Hettinger6065d322004-12-20 23:51:53 +00001457- StringIO.truncate() now correctly adjusts the size attribute.
1458 (Bug #951915).
1459
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001460- locale.py now uses an updated locale alias table (built using
1461 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1462 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001463 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001464
Raymond Hettinger3557f422004-12-07 12:02:02 +00001465- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1466
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001467- the pickle module no longer accepts the deprecated None option in the
1468 args tuple returned by __reduce__().
1469
Brett Cannon84667c02004-12-07 03:25:18 +00001470- optparse now optionally imports gettext. This allows its use in setup.py.
1471
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001472- the pickle module no longer uses the deprecated bin parameter.
1473
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001474- the shelve module no longer uses the deprecated binary parameter.
1475

1477
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001478- the filecmp module no longer uses the deprecated use_statcache argument.
1479
Raymond Hettinger664347b2004-12-04 21:21:53 +00001480- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1481 extended or overridden by subclasses. Formerly, the subclassed method would
1482 be ignored by the rest of the module. (Bug #1078905).
1483
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001484- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001485 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001486
Walter Dörwald36733692004-12-22 12:50:50 +00001487- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1488 once when a size argument is given. This prevents a buffer overflow in the
1489 tokenizer with very long source lines.
1490
Barry Warsaw538561e2006-01-01 21:48:54 +00001491- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1492 immediately after creating the object, without any intervening
1493 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001494
Skip Montanaro05885812005-01-16 20:48:27 +00001495- The reconvert.quote function can now emit triple-quoted strings. The
1496 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001497
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001498- ``UserString.MutableString`` now supports negative indices in
1499 ``__setitem__`` and ``__delitem__``
1500
Greg Ward40407942005-03-05 02:53:17 +00001501- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1502 correctly.
1503
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001504- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1505 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1506 character even if the user has passed a size parameter to get a proper
1507 line ending. Remove the special handling of a "\r\n" that has been split
1508 between two lines.
1509
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001510- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1511 about illegal code points. The codec now supports PEP 293 style error
1512 handlers.
1513
Walter Dörwald78a78b02005-09-01 12:04:29 +00001514- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001515 from the input stream, so that the output is a byte string in the correct
1516 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001517
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001518- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1519 considering it exactly like a '*'.
1520
Walter Dörwald007f8df2005-10-09 19:42:27 +00001521- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1522 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001523
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001524- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1525
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001526- Patch #1413711: Certain patterns of differences were making difflib
1527 touch the recursion limit.
1528
Walter Dörwald58917a62006-03-31 15:26:22 +00001529- Bug #947906: An object oriented interface has been added to the calendar
1530 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001531 called as a script (e.g. via ``python -mcalendar``). Localized month and
1532 weekday names can be ouput (even if an exotic encoding is used) using
1533 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001534

1536-----
1537
Neal Norwitz602d3392006-03-31 08:21:40 +00001538- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1539 by using -mieee gcc option.
1540
Martin v. Löwis86d66262006-02-17 08:40:11 +00001541- Patch #1432345: Make python compile on DragonFly.
1542
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001543- Build support for Win64-AMD64 was added.
1544
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001545- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1546
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001547- Patch #881820: look for openpty and forkpty also in libbsd.
1548
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001549- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1550 The zlib module is now builtin on Windows.
1551
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001552- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1553
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001554- Bug #1189330: configure did not correctly determine the necessary
1555 value of LINKCC if python was built with GCC 4.0.
1556
Trent Mick8321b422005-07-26 02:29:21 +00001557- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1558 vulnerability in zlib 1.2.1 and 1.2.2.
1559
Brett Cannon08cd5982005-04-24 22:26:38 +00001560- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1561 flags that change binary compatibility. Changes were also made to
1562 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001563 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001564
Bob Ippolitoed233462005-03-29 13:47:59 +00001565- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1566 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1567 no longer exists). This configure patch makes things right.
1568
Martin v. Löwise2713be2005-03-08 15:03:08 +00001569- Bug #1158607: Build with --disable-unicode again.
1570
Brett Cannon46d96232005-02-16 00:07:19 +00001571- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1572 defined. Discovered as a result of not being able to build on OS X.
1573
Brett Cannon516592f2004-12-07 00:42:59 +00001574- setup.py now uses the directories specified in LDFLAGS using the -L option
1575 and in CPPFLAGS using the -I option for adding library and include
1576 directories, respectively, for compiling extension modules against. This has
1577 led to the core being compiled using the values in CPPFLAGS. It also removes
1578 the need for the special-casing of both DarwinPorts and Fink for darwin since
1579 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1580 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1581 Fink, ``-I/opt/local/include`` for DarwinPorts).
1582
Brett Cannon43802422005-02-10 20:48:03 +00001583- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1584 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1585 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1586 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001588C API
1589-----
1590
Tim Petersc9d78aa2006-03-26 23:27:58 +00001591- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1592 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1593 is obtained via the ``PyObject_`` family, it must be released via the
1594 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1595 always been officially true, but when Python's small-object allocator was
1596 introduced, an attempt was made to cater to a few extension modules
1597 discovered at the time that obtained memory via ``PyObject_New`` but
1598 released it via ``PyMem_DEL``. It's years later, and if such code still
1599 exists it will fail now (probably with segfaults, but calling wrong
1600 low-level memory management functions can yield many symptoms).
1601
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001602- Added a C API for set and frozenset objects.
1603
Raymond Hettinger66517482004-12-03 11:45:13 +00001604- Removed PyRange_New().
1605
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001606- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1607 mapping argument now. This string is used as a mapping table. Byte values
1608 greater than the length of the string and 0xFFFE are treated as undefined
1609 mappings.
