Hye-Shik Change6a1cb92006-06-23 21:16:18 +000021- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
22 omit a default "error" argument for NULL pointer. This allows
23 the parser to take a codec from cjkcodecs again.

41 is created.
42
Martin v. Löwis7596e832006-07-01 15:33:37 +000043- Bug #1513223: .close() of a _socketobj now releases the underlying
44 socket again, which then gets closed as it becomes unreferenced.
45
Thomas Hellerbde08132006-06-29 18:34:15 +000046- The '_ctypes' extension module now works when Python is configured
47 with the --without-threads option.

56
Brett Cannon53ab5b72006-06-22 16:49:14 +000057- Bug #1510580: The 'warnings' module improperly required that a Warning
58 category be either a types.ClassType and a subclass of Warning. The proper
59 check is just that it is a subclass with Warning as the documentation states.
60
Georg Brandlad29e632006-06-21 17:45:17 +000061- The compiler module now correctly compiles the new try-except-finally

105Core and builtins
106-----------------
107
Georg Brandla56b9152006-06-19 06:35:54 +0000108- Patch #1507676: Error messages returned by invalid abstract object operations
109 (such as iterating over an integer) have been improved and now include the
110 type of the offending object to help with debugging.
111
Brett Cannonea3912b2006-06-13 21:46:41 +0000112- Bug #992017: A classic class that defined a __coerce__() method that returned
113 its arguments swapped would infinitely recurse and segfault the interpreter.
114
Neal Norwitz909eb122006-06-12 02:13:21 +0000115- Fix the socket tests so they can be run concurrently.
116
Neal Norwitzb9845e72006-06-12 02:11:18 +0000117- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000118 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000119
Brett Cannon22565aa2006-06-09 22:31:23 +0000120- Bug #532646: object.__call__() will continue looking for the __call__
121 attribute on objects until one without one is found. This leads to recursion
122 when you take a class and set its __call__ attribute to an instance of the
123 class. Originally fixed for classic classes, but this fix is for new-style.
124 Removes the infinite_rec_3 crasher.
125
Georg Brandl24250812006-06-09 18:45:48 +0000126- The string and unicode methods startswith() and endswith() now accept
127 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
128
Brett Cannonde3b0522006-06-08 17:00:45 +0000129- Buffer objects, at the C level, never used the char buffer
130 implementation even when the char buffer for the wrapped object was
131 explicitly requested (originally returned the read or write buffer).
132 Now a TypeError is raised if the char buffer is not present but is
133 requested.
134
Georg Brandlddbaa662006-06-04 21:56:52 +0000135- Patch #1346214: Statements like "if 0: suite" are now again optimized
136 away like they were in Python 2.4.
137
Georg Brandlb7c8f542006-05-27 12:30:25 +0000138- Builtin exceptions are now full-blown new-style classes instead of
139 instances pretending to be classes, which speeds up exception handling
140 by about 80% in comparison to 2.5a2.
141
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000142- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
143 Unicode 4.1.
144
Georg Brandlf4ef1162006-05-26 18:03:31 +0000145- Patch #921466: sys.path_importer_cache is now used to cache valid and
146 invalid file paths for the built-in import machinery which leads to
147 fewer open calls on startup.
148
Tim Peters696cf432006-05-24 21:10:40 +0000149- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
150 of-2 bases. The largest speedup is for inputs with about 1000 decimal
151 digits. Conversion from non-power-of-2 bases remains quadratic-time in
152 the number of input digits (it was and remains linear-time for bases
153 2, 4, 8, 16 and 32).
154
Tim Petersb713ec22006-05-23 18:45:30 +0000155- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
156 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
157 an integer close to ``sys.maxint``. This was repaired by patch
158 #1335972, which also gives a nice speedup.
159
Richard Jonescebbefc2006-05-23 18:28:17 +0000160- Patch #1337051: reduced size of frame objects.
161
162- PyErr_NewException now accepts a tuple of base classes as its
163 "base" parameter.
164
Richard Jones7c88dcc2006-05-23 10:37:38 +0000165- Patch #876206: function call speedup by retaining allocated frame
166 objects.
167
Georg Brandl7b90e162006-05-18 07:01:27 +0000168- Bug #1462152: file() now checks more thoroughly for invalid mode
169 strings and removes a possible "U" before passing the mode to the
170 C library function.
171
Neal Norwitz1004a532006-05-15 07:17:23 +0000172- Patch #1488312, Fix memory alignment problem on SPARC in unicode
173
Neal Norwitz373f0a72006-05-15 07:04:36 +0000174- Bug #1487966: Fix SystemError with conditional expression in assignment
175
Martin v. Löwis879768d2006-05-11 13:28:43 +0000176- WindowsError now has two error code attributes: errno, which carries
177 the error values from errno.h, and winerror, which carries the error
178 values from winerror.h. Previous versions put the winerror.h values
179 (from GetLastError()) into the errno attribute.
180
Martin v. Löwis77736712006-05-04 05:51:03 +0000181- Patch #1475845: Raise IndentationError for unexpected indent.
182
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000183- Patch #1479181: split open() and file() from being aliases for each other.
184
Tim Peters44bd9862006-06-01 13:49:23 +0000185- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
186 methods were always silently ignored by dictionaries when comparing keys.
187 They are now passed through (except when using the C API function
188 ``PyDict_GetItem()``, whose semantics did not change).
189
190- Bug #1456209: In some obscure cases it was possible for a class with a
191 custom ``__eq__()`` method to confuse dict internals when class instances
192 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
193 No, you don't have any code that did this ;-)

199
200- Patch #1462338: Upgrade pyexpat to expat 2.0.0
201
Brett Cannon6ee7d012006-06-08 16:23:04 +0000202- Change binascii.hexlify to accept a read-only buffer instead of only a char
203 buffer and actually follow its documentation.
204
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000205- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
206
Nick Coghlanc649ec52006-05-29 12:43:05 +0000207- Patch #1478788 (modified version): The functional extension module has
208 been renamed to _functools and a functools Python wrapper module added.
209 This provides a home for additional function related utilities that are
210 not specifically about functional programming. See PEP 309.
211
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000212- Patch #1493701: performance enhancements for struct module.

220 enabled builds on Windows and systems with Posix threads support.
221
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000222- On Win32, os.listdir now supports arbitrarily-long Unicode path names
223 (up to the system limit of 32K characters).
224
225- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
226 As a result, these functions now raise WindowsError instead of OSError.
227
Tim Peters7a822da2006-05-25 21:50:17 +0000228- ``time.clock()`` on Win64 should use the high-performance Windows
229 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
230 Windows platforms).
231
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000232- Calling Tk_Init twice is refused if the first call failed as that
233 may deadlock.
234
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000235- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
236 accept it without potentially using an uninitialized pointer.
237
238- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
239 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
240 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000241
Gregory P. Smith372b5832006-06-05 18:48:21 +0000242- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000243 [pybsddb project SF patch number 1466734]
244
Gregory P. Smith372b5832006-06-05 18:48:21 +0000245- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
246 parameter is supplied. [SF pybsddb bug #1477863]
247
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000248- bsddb: the __len__ method of a DB object has been fixed to return correct
249 results. It could previously incorrectly return 0 in some cases.
250 Fixes SF bug 1493322 (pybsddb bug 1184012).
251
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000252- bsddb: the bsddb.dbtables Modify method now raises the proper error and
253 aborts the db transaction safely when a modifier callback fails.
254 Fixes SF python patch/bug #1408584.
255
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000256- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000257 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000258 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
259 database calls that would previously deadlock. [SF python bug #775414]
260
Vinay Sajip28e57612006-07-01 10:45:20 +0000261- Patch #1446489: add support for the ZIP64 extensions to zipfile.

289 double-byte encodings.
290
Tim Peters43898b42006-06-14 04:09:25 +0000291- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
292 guarantee that adjacent triples in the return list always describe
293 non-adjacent blocks. Previously, a pair of matching blocks could end
294 up being described by multiple adjacent triples that formed a partition
295 of the matching pair.
296
Greg Ward0e0c9f42006-06-11 16:24:11 +0000297- Bug #1498146: fix optparse to handle Unicode strings in option help,

Nick Coghlan676725d2006-06-08 13:54:49 +0000307- The functions update_wrapper() and wraps() have been added to the functools
308 module. These make it easier to copy relevant metadata from the original
309 function when writing wrapper functions.
310
Tim Petersd6a9eef2006-06-05 01:48:21 +0000311- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
312 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000313
Martin v. Löwis3f767792006-06-04 19:36:28 +0000314- Patch #1359618: Speed up charmap encoder by using a trie structure
315 for lookup.
316
Tim Petersd609b1a2006-06-02 23:22:51 +0000317- The functions in the ``pprint`` module now sort dictionaries by key
318 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
319 if and only if its display required more than one line, although that
320 wasn't documented. The new behavior increases predictability; e.g.,
321 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
322
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000323- Patch #1497027: try HTTP digest auth before basic auth in urllib2
324 (thanks for J. J. Lee).
325
Georg Brandl2b330372006-05-28 20:23:12 +0000326- Patch #1496206: improve urllib2 handling of passwords with respect to
327 default HTTP and HTTPS ports.
328
George Yoshidaf3c65de2006-05-28 16:39:09 +0000329- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
330
Bob Ippolito7298f272006-05-23 18:43:47 +0000331- Patch #1281707: speed up gzip.readline.
332
Georg Brandlb89316f2006-05-17 15:51:16 +0000333- Patch #1180296: Two new functions were added to the locale module:
334 format_string() to get the effect of "format % items" but locale-aware,
335 and currency() to format a monetary number with currency sign.
336
Georg Brandle3a25832006-05-17 14:56:04 +0000337- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
338 and several features added, such as speed and geometry control.
339
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000340- Patch #1488881: add support for external file objects in bz2 compressed
341 tarfiles.
342
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000343- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
344 stdout arguments, making it possible to redirect input and output
345 for remote debugging.
346
347- Patch #1484695: Update the tarfile module to version 0.8. This fixes
348 a couple of issues, notably handling of long file names using the
349 GNU LONGNAME extension.
350
351- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
352 new flag when ``name`` is already the name of an option flag.
353
354- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
355 package.
356
357- Patch #1472854: make the rlcompleter.Completer class usable on non-
358 UNIX platforms.
359
360- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
361
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000362- Bug #1472827: correctly escape newlines and tabs in attribute values in
363 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000393What's New in Python 2.5 alpha 2?
394=================================
395
396*Release date: 27-APR-2006*
397
398Core and builtins
399-----------------
400
Thomas Heller1b046642006-04-18 18:51:06 +0000401- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
402 by converting these apis from macros into exported functions again:
403
404 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
405 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
406 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
407 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
408 PyRun_String Py_CompileString
409
Martin v. Löwis45294a92006-04-18 06:24:08 +0000410- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
411
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000412- All uses of PyStructSequence_InitType have been changed to initialize
413 the type objects only once, even if the interpreter is initialized
414 multiple times.
415
Neal Norwitz61546162006-04-14 05:20:28 +0000416- Bug #1454485, array.array('u') could crash the interpreter. This was
417 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
418 to unicode when it didn't make sense. 'u#' now requires a unicode string.
419
420- Py_UNICODE is unsigned. It was always documented as unsigned, but
421 due to a bug had a signed value in previous versions.
422
Tim Peters3a5e8b12006-04-11 01:44:07 +0000423- Patch #837242: ``id()`` of any Python object always gives a positive
424 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
425 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000426 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000427 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000428
Tim Peters3a5e8b12006-04-11 01:44:07 +0000429 def __hash__(self):
430 return id(self) # WRONG
431
432 because a hash result must be a (short) Python int but it was always
433 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000434 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000435 was always usable as a hash value before this patch. That's no longer
436 necessarily so.
437
438- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000439 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000440 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000441 #1454844)
442
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000443- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
444 involving generators that have paused outside of any ``try`` or ``with``
445 blocks. (In 2.5a1, a paused generator that was part of a reference
446 cycle could not be garbage collected, regardless of whether it was
447 paused in a ``try`` or ``with`` block.)

456 fails with an error condition.
457
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000458- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

460- Bug #1117761: bsddb.*open() no longer raises an exception when using
461 the cachesize parameter.
462
463- Bug #1149413: bsddb.*open() no longer raises an exception when using
464 a temporary db (file=None) with the 'n' flag to truncate on open.
465
466- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
467 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000468
Armin Rigoa9017c32006-04-19 11:50:27 +0000469- Patch #1062014: AF_UNIX sockets under Linux have a special
470 abstract namespace that is now fully supported.

474
Tim Peters711bf302006-04-25 03:31:36 +0000475- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
476 a doctest to be skipped (the code is not run, and the expected output
477 or exception is ignored).
478
Nick Coghlanda2268f2006-04-24 04:37:15 +0000479- Fixed contextlib.nested to cope with exceptions being raised and
480 caught inside exit handlers.
481
Greg Wardab05edc2006-04-23 03:47:58 +0000482- Updated optparse module to Optik 1.5.1 (allow numeric constants in
483 hex, octal, or binary; add ``append_const`` action; keep going if
484 gettext cannot be imported; added ``OptionParser.destroy()`` method;
485 added ``epilog`` for better help generation).
486
Tim Peters21fbd572006-04-21 21:18:10 +0000487- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
488 called from a thread spawned as a side effect of importing a module.
489
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000490- The pydoc module now supports documenting packages contained in
491 .zip or .egg files.
492
493- The pkgutil module now has several new utility functions, such
494 as ``walk_packages()`` to support working with packages that are either
495 in the filesystem or zip files.
496
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000497- The mailbox module can now modify and delete messages from
498 mailboxes, in addition to simply reading them. Thanks to Gregory
499 K. Johnson for writing the code, and to the 2005 Google Summer of
500 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000501
Tim Petersc7605f22006-04-17 21:12:33 +0000502- The ``__del__`` method of class ``local`` in module ``_threading_local``
503 returned before accomplishing any of its intended cleanup.
504
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000505- Patch #790710: Add breakpoint command lists in pdb.
506
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000507- Patch #1063914: Add Tkinter.Misc.clipboard_get().
508
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000509- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
510
Anthony Baxtere29002c2006-04-12 12:07:31 +0000511- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
512 Windows. Bug #1469163.
513
Phillip J. Eby47032112006-04-11 01:07:43 +0000514- The warnings, linecache, inspect, traceback, site, and doctest modules
515 were updated to work correctly with modules imported from zipfiles or
516 via other PEP 302 __loader__ objects.
517
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000518- Patch #1467770: Reduce usage of subprocess._active to processes which
519 the application hasn't waited on.
520

530
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000531- The Makefile now has a reindent target, which runs reindent.py on
532 the library.
533

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000537
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000538- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
539 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000540 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000541 CXX from --with-cxx-main, see description in README.
542
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000543- Patch #1429775: Link extension modules with the shared libpython.
544
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000545- Fixed a libffi build problem on MIPS systems.
546
Tim Peters8931ff12006-05-13 23:28:20 +0000547- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
548 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
549 and "%zu" for unsigned integers of type ``size_t``.
550
Anthony Baxter51bcb682006-04-05 14:51:42 +0000551Tests
552-----
553
Nick Coghlanda2268f2006-04-24 04:37:15 +0000554- test_contextlib now checks contextlib.nested can cope with exceptions
555 being raised and caught inside exit handlers.
556
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000557- test_cmd_line now checks operation of the -m and -c command switches
558
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000559- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
560 it separately and by hand. It also wasn't cleaning up its changes to
561 the current Decimal context.
562
Thomas Woutersabd08882006-04-26 15:53:30 +0000563- regrtest.py now has a -M option to run tests that test the new limits of
564 containers, on 64-bit architectures. Running these tests is only sensible
565 on 64-bit machines with more than two gigabytes of memory. The argument
566 passed is the maximum amount of memory for the tests to use.

575-------------
576
Tim Petersb06d28c2006-05-12 01:57:59 +0000577- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
578
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000579- PEP 343: Added Context Types section to the library reference
580 and attempted to bring other PEP 343 related documentation into
581 line with the implementation and/or python-dev discussions.
582
Tim Peters8dc73d22006-04-24 02:03:16 +0000583- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000587What's New in Python 2.5 alpha 1?
588=================================

Anthony Baxterebed3f62006-04-03 15:03:44 +0000590*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000591
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000592Core and builtins
593-----------------
594
Nick Coghlan43832302006-04-23 17:04:07 +0000595- PEP 338: -m command line switch now delegates to runpy.run_module
596 allowing it to support modules in packages and zipfiles
597
Martin v. Löwisc661b882006-04-20 04:54:23 +0000598- On Windows, .DLL is not an accepted file name extension for
599 extension modules anymore; extensions are only found if they
600 end in .PYD.
601
Martin v. Löwisea62d252006-04-03 10:56:49 +0000602- Bug #1421664: sys.stderr.encoding is now set to the same value as
603 sys.stdout.encoding.
604
Neal Norwitz92e212f2006-04-03 04:48:37 +0000605- __import__ accepts keyword arguments.
606
Georg Brandlccadf842006-03-31 18:54:53 +0000607- Patch #1460496: round() now accepts keyword arguments.
608
Anthony Baxter262c00a2006-03-30 10:53:17 +0000609- Fixed bug #1459029 - unicode reprs were double-escaped.
610
Hye-Shik Changd478f342006-03-23 12:32:36 +0000611- Patch #1396919: The system scope threads are reenabled on FreeBSD
612 5.4 and later versions.
613
Neal Norwitze98ccf62006-03-23 05:39:47 +0000614- Bug #1115379: Compiling a Unicode string with an encoding declaration
615 now gives a SyntaxError.
616
Georg Brandlabd1ff82006-03-18 07:59:59 +0000617- Previously, Python code had no easy way to access the contents of a
618 cell object. Now, a ``cell_contents`` attribute has been added
619 (closes patch #1170323).
620
Tim Peterscf79aac2006-03-16 01:14:46 +0000621- Patch #1123430: Python's small-object allocator now returns an arena to
622 the system ``free()`` when all memory within an arena becomes unused
623 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
624 freed. Some applications will see a drop in virtual memory size now,
625 especially long-running applications that, from time to time, temporarily
626 use a large number of small objects. Note that when Python returns an
627 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000628 platform C library will in turn return that memory to the operating system.
629 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000630 appears to be effective at least on Microsoft C and gcc-based systems.
631 Thanks to Evan Jones for hard work and patience.

Georg Brandl533ff6f2006-03-08 18:09:27 +0000633- Patch #1434038: property() now uses the getter's docstring if there is
634 no "doc" argument given. This makes it possible to legitimately use
635 property() as a decorator to produce a read-only property.
636
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000637- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
638 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
639 of requiring an int or long in slicing and a few other contexts, enabling
640 other objects (e.g. Numeric Python's integers) to be used as slice indices.
641
Neal Norwitz995acdf2006-03-07 05:01:00 +0000642- Fixed various bugs reported by Coverity's Prevent tool.
643
Brett Cannonbf364092006-03-01 04:25:17 +0000644- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
645 new exception base class, BaseException, which has a new message attribute.
646 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
647 Raising a string exception now raises a DeprecationWarning.
648
Thomas Woutersfb609f42006-02-28 16:37:25 +0000649- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
650 explicitly relative, using 'from .module import name' to mean 'from the same
651 package as this module is in. Imports without dots still default to the
652 old relative-then-absolute, unless 'from __future__ import
653 absolute_import' is used.
654
Brett Cannona7446e32006-02-27 23:39:10 +0000655- Properly check if 'warnings' raises an exception (usually when a filter set
656 to "error" is triggered) when raising a warning for raising string
657 exceptions.
658
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000659- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000660 The name was removed from Include/code.h.
661
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000662- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000663
Guido van Rossum1968ad32006-02-25 22:38:04 +0000664- Patch 1433928:
665 - The copy module now "copies" function objects (as atomic objects).
666 - dict.__getitem__ now looks for a __missing__ hook before raising
667 KeyError.
668
Tim Peters84ef21c2006-02-28 20:39:06 +0000669- PEP 343: with statement implemented. Needs ``from __future__ import
670 with_statement``. Use of 'with' as a variable will generate a warning.
671 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000672 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000673 The following objects have __context__ methods:
674 - The built-in file type.
675 - The thread.LockType type.
676 - The following types defined by the threading module:
677 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
678 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000679
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000680- Fix the encodings package codec search function to only search
681 inside its own package. Fixes problem reported in patch #1433198.
682
683 Note: Codec packages should implement and register their own
684 codec search function. PEP 100 has the details.
685
Tim Peters9ea89d22006-06-04 03:26:02 +0000686- PEP 353: Using ``Py_ssize_t`` as the index type.
687
688- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
689 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
690 now allow Python to make use of memory blocks exceeding 2**32 bytes for
691 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
692 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000693
Neal Norwitzfc76d632006-01-10 06:03:13 +0000694- Patch #1400181, fix unicode string formatting to not use the locale.
695 This is how string objects work. u'%f' could use , instead of .
696 for the decimal point. Now both strings and unicode always use periods.
697
Neal Norwitz671b9e32006-01-09 07:07:12 +0000698- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
699 configure would break checking curses.h.
700
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000701- Bug #959576: The pwd module is now builtin. This allows Python to be
702 built on UNIX platforms without $HOME set.
703
Neal Norwitzc10978f2005-12-19 06:07:16 +0000704- Bug #1072182, fix some potential problems if characters are signed.
705
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000706- Bug #889500, fix line number on SyntaxWarning for global declarations.
707
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000708- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
709
Neal Norwitze7214a12005-12-18 05:03:17 +0000710- Support for converting hex strings to floats no longer works.
711 This was not portable. float('0x3') now raises a ValueError.
712
Barry Warsaw2a38a862005-12-18 01:27:35 +0000713- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000714 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000715 is now displayed in interactive prompt banner.
716
Georg Brandlfa166682005-12-17 21:45:17 +0000717- Implementation of PEP 341 - Unification of try/except and try/finally.
718 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000719 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000720
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000721- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
722 now encodes backslash correctly.
723
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000724- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
725
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000726- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000727 and long longs.
728
Neal Norwitz67715f02005-11-09 06:59:35 +0000729- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000730 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000731 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000732
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000733- Replaced most Unicode charmap codecs with new ones using the
734 new Unicode translate string feature in the builtin charmap
735 codec; the codecs were created from the mapping tables available
736 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
737 encodings now include a mapping for the Apple logo)
738
Tim Peterse3547fd2005-12-16 23:13:57 +0000739- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000740
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000741- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000742
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000743- A new AST parser implementation was completed. The abstract
744 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000745 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000746
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000747- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000748 The following code now raises a SyntaxError: foo(a = i for i in range(10))
749
Neal Norwitz708e51a2005-10-03 04:48:15 +0000750- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
751
Neal Norwitz11bd1192005-10-03 00:54:56 +0000752- SF Bug #887946: fix segfault when redirecting stdin from a directory.
753 Provide a warning when a directory is passed on the command line.
754
Neal Norwitz40d37812005-10-02 01:48:49 +0000755- Fix segfault with invalid coding.
756
757- SF bug #772896: unknown encoding results in MemoryError.
758
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000759- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000760 supported a __len__() method which evaluated to False when the iterator
761 was empty.
762
Guido van Rossum630db602005-09-20 18:49:54 +0000763- On 64-bit platforms, when __len__() returns a value that cannot be
764 represented as a C int, raise OverflowError.
765
Skip Montanarof8948ca2005-09-19 03:54:46 +0000766- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000767 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000768
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000769- SF bug #893549: parsing keyword arguments was broken with a few format
770 codes.
771
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000772- Changes donated by Elemental Security to make it work on AIX 5.3
773 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
774 bug #105470: test_pwd fails on 64bit system (Opteron).
775
Guido van Rossum539c6622005-09-14 17:49:54 +0000776- Changes donated by Elemental Security to make it work on HP-UX 11 on
777 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
778
Georg Brandl4550b8d2005-08-26 06:43:52 +0000779- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000780 (fixes bug #1119418).
781
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000782- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
783
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000784- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
785 exceptions that cause a function to exit.
786
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000787- The implementation of set() and frozenset() was revised to use its
788 own internal data structure. Memory consumption is reduced by 1/3
789 and there are modest speed-ups as well. The API is unchanged.
790
Tim Petersde7990b2005-07-17 23:45:23 +0000791- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
792
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000793- SF bug #1229429: PyObject_CallMethod failed to decrement some
794 reference counts in some error exit cases.
795
Tim Petersecc6e6a2005-07-10 22:30:55 +0000796- SF bug #1185883: Python's small-object memory allocator took over
797 a block managed by the platform C library whenever a realloc specified
798 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000799 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000800 portable way to copy data from the C-managed block into Python's
801 small-object space without risking a memory fault. Python's small-object
802 realloc now leaves such blocks under the control of the platform C
803 realloc.
804
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000805- SF bug #1232517: An overflow error was not detected properly when
806 attempting to convert a large float to an int in os.utime().
807
Raymond Hettinger3296e692005-06-29 23:29:56 +0000808- SF bug #1224347: hex longs now print with lowercase letters just
809 like their int counterparts.
810
Michael W. Hudson188d4362005-06-20 16:52:57 +0000811- SF bug #1163563: the original fix for bug #1010677 ("thread Module
812 Breaks PyGILState_Ensure()") broke badly in the case of multiple
813 interpreter states; back out that fix and do a better job (see
814 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
815 for a longer write-up of the problem).
816
Michael W. Hudsondf888462005-06-03 14:41:55 +0000817- SF patch #1180995: marshal now uses a binary format by default when
818 serializing floats.
819
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000820- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
821 the routines that promise to produce IEEE 754 binary representations
822 of floats now simply copy bytes around.
823
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000824- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
825 278.
826
Brett Cannonc3647ac2005-04-26 03:45:26 +0000827- patch #1109424: int, long, float, complex, and unicode now check for the
828 proper magic slot for type conversions when subclassed. Previously the
829 magic slot was ignored during conversion. Semantics now match the way
830 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000831 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000832 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000833 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000834
Barry Warsawc8d907c2005-04-19 23:43:40 +0000835- Descriptors defined in C with a PyGetSetDef structure, where the setter is
836 NULL, now raise an AttributeError when attempting to set or delete the
837 attribute. Previously a TypeError was raised, but this was inconsistent
838 with the equivalent pure-Python implementation.
839
Michael W. Hudson774479c2005-04-18 08:46:17 +0000840- It is now safe to call PyGILState_Release() before
841 PyEval_InitThreads() (note that if there is reason to believe there
842 are multiple threads around you still must call PyEval_InitThreads()
843 before using the Python API; this fix is for extension modules that
844 have no way of knowing if Python is multi-threaded yet).
845
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000846- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
847 disabled caused a crash.
848
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000849- Bug #1165306: instancemethod_new allowed the creation of a method
850 with im_class == im_self == NULL, which caused a crash when called.
851
Tim Petersecc6e6a2005-07-10 22:30:55 +0000852- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000853 fixes the crash seen in bug #1165761
854
Raymond Hettinger96229b12005-03-11 06:49:40 +0000855- Added two new builtins, any() and all().
856
Brett Cannon409d8f22005-03-05 06:47:57 +0000857- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000858 (e.g., ``class C(): pass`` is no longer a syntax error).
859 Patch #1176012 added support to the 'parser' module and 'compiler' package
860 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000861
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000862- Patch #1115086: Support PY_LONGLONG in structmember.
863
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000864- Bug #1155938: new style classes did not check that __init__() was
865 returning None.
866
Tim Petersecc6e6a2005-07-10 22:30:55 +0000867- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000868 ('\') with a specific error message.
869
Martin v. Löwisff232d72005-03-03 09:24:38 +0000870- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
871
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000872- Bug #1124295: the __name__ attribute of file objects was
873 inadvertently made inaccessible in restricted mode.
874
Tim Petersecc6e6a2005-07-10 22:30:55 +0000875- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000876 an ferror() call.
877
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000878- min() and max() now support key= arguments with the same meaning as in
879 list.sort().
880
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000881- The peephole optimizer now performs simple constant folding in expressions:
882 (2+3) --> (5).
883
Raymond Hettingera422c342005-01-11 03:03:27 +0000884- set and frozenset objects can now be marshalled. SF #1098985.
885
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000886- Bug #1077106: Poor argument checking could cause memory corruption
887 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000888
Jeremy Hyltonab630502005-02-04 18:44:06 +0000889- The parser did not complain about future statements in illegal
890 positions. It once again reports a syntax error if a future
891 statement occurs after anything other than a doc string.
892
Neil Schemenauercf52c072005-08-12 17:34:58 +0000893- Change the %s format specifier for str objects so that it returns a
894 unicode instance if the argument is not an instance of basestring and
895 calling __str__ on the argument returns a unicode instance.
896
Tim Petersf4e69282006-02-27 17:15:31 +0000897- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
898 current thread state when the auto-GIL-state machinery knows about
899 it (since the thread state is being deleted, continuing to remember it
900 can't help, but can hurt if another thread happens to get created with
901 the same thread id).

1094 executing modules which provide access to source code or a code object
1095 via the PEP 302 import mechanisms.

Georg Brandl828fdef2006-04-01 08:59:03 +00001108 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001109 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001110 module will not be built.
1111
Tim Petersc17976e2006-04-01 00:26:53 +00001112- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1113 aren't officially supported here, and trying to use them will probably
1114 raise an exception some day. But dicts have been allowed, and "mostly
1115 worked", so support for them won't go away without warning.
1116
Georg Brandl338ef7d2006-03-31 18:42:16 +00001117- Bug #1445068: getpass.getpass() can now be given an explicit stream
1118 argument to specify where to write the prompt.
1119

1135
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001136- email 4.0 package now integrated. This is largely the same as the email 3.0
1137 package that was included in Python 2.3, except that PEP 8 module names are
1138 now used (e.g. mail.message instead of email.Message). The MIME classes
1139 have been moved to a subpackage (e.g. email.mime.text instead of
1140 email.MIMEText). The old names are still supported for now. Several
1141 deprecated Message methods have been removed and lots of bugs have been
1142 fixed. More details can be found in the email package documentation.
1143
Walter Dörwald40108c92006-03-27 08:15:44 +00001144- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1145 (a subclass of tuple) that provides incremental decoders and encoders
1146 (a way to use stateful codecs without the stream API). Python functions
1147 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1148 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1149 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001150
Walter Dörwald067db482006-03-15 22:17:27 +00001151- Patch #1359365: Calling next() on a closed StringIO.String object raises
1152 a ValueError instead of a StopIteration now (like file and cString.String do).
1153 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1154 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001155
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001156- A regrtest option -w was added to re-run failed tests in verbose mode.

1168 and helpful context managers nested() and closing().
1169
Martin v. Löwis415ed932006-02-27 19:56:30 +00001170- The compiler package now supports future imports after the module docstring.

1230 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1231 Ronald L. Rivest offered this advice for Python:
1232
1233 "The consensus of researchers in this area (at least as
1234 expressed at the NIST Hash Function Workshop 10/31/05),
1235 is that SHA-256 is a good choice for the time being, but
1236 that research should continue, and other alternatives may
1237 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001238

1419 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001420 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001421 PEP 305.

1425 dictates.
1426 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001427 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001428 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001429 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1430 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001431 + reader now allows \r characters to be quoted (previously it only allowed
1432 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001433 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001434 + Dialect classes passed to the module are no longer instantiated by
1435 the module before being parsed (the former validation scheme required
1436 this, but the mechanism was unreliable).
1437 + The dialect registry now contains instances of the internal
1438 C-coded dialect type, rather than references to python objects.
1439 + the internal c-coded dialect type is now immutable.
1440 + register_dialect now accepts the same keyword dialect specifications
1441 as the reader and writer, allowing the user to register dialects
1442 without first creating a dialect class.
1443 + a configurable limit to the size of parsed fields has been added -
1444 previously, an unmatched quote character could result in the entire
1445 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001446 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001447 the parser field size limit (returning the former limit). The initial
1448 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001449 + A line_num attribute has been added to the reader object, which tracks
1450 the number of lines read from the source iterator. This is not
1451 the same as the number of records returned, as records can span
1452 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001453 + reader and writer objects were not being registered with the cyclic-GC.
1454 This has been fixed.
1455
Brett Cannone6539c42005-01-08 02:43:53 +00001456- _DummyThread objects in the threading module now delete self.__block that is
1457 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1458 lock primitives tend to be limited in number and thus should not be wasted on
1459 a _DummyThread object. Fixes bug #1089632.
1460
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001461- The imghdr module now detects Exif files.
1462
Raymond Hettinger6065d322004-12-20 23:51:53 +00001463- StringIO.truncate() now correctly adjusts the size attribute.
1464 (Bug #951915).
1465
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001466- locale.py now uses an updated locale alias table (built using
1467 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1468 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001469 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001470
Raymond Hettinger3557f422004-12-07 12:02:02 +00001471- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1472
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001473- the pickle module no longer accepts the deprecated None option in the
1474 args tuple returned by __reduce__().
1475
Brett Cannon84667c02004-12-07 03:25:18 +00001476- optparse now optionally imports gettext. This allows its use in setup.py.
1477
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001478- the pickle module no longer uses the deprecated bin parameter.
1479
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001480- the shelve module no longer uses the deprecated binary parameter.
1481

1483
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001484- the filecmp module no longer uses the deprecated use_statcache argument.
1485
Raymond Hettinger664347b2004-12-04 21:21:53 +00001486- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1487 extended or overridden by subclasses. Formerly, the subclassed method would
1488 be ignored by the rest of the module. (Bug #1078905).
1489
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001490- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001491 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001492
Walter Dörwald36733692004-12-22 12:50:50 +00001493- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1494 once when a size argument is given. This prevents a buffer overflow in the
1495 tokenizer with very long source lines.
1496
Barry Warsaw538561e2006-01-01 21:48:54 +00001497- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1498 immediately after creating the object, without any intervening
1499 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001500
Skip Montanaro05885812005-01-16 20:48:27 +00001501- The reconvert.quote function can now emit triple-quoted strings. The
1502 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001503
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001504- ``UserString.MutableString`` now supports negative indices in
1505 ``__setitem__`` and ``__delitem__``
1506
Greg Ward40407942005-03-05 02:53:17 +00001507- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1508 correctly.
1509
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001510- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1511 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1512 character even if the user has passed a size parameter to get a proper
1513 line ending. Remove the special handling of a "\r\n" that has been split
1514 between two lines.
1515
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001516- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1517 about illegal code points. The codec now supports PEP 293 style error
1518 handlers.
1519
Walter Dörwald78a78b02005-09-01 12:04:29 +00001520- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001521 from the input stream, so that the output is a byte string in the correct
1522 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001523
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001524- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1525 considering it exactly like a '*'.
1526
Walter Dörwald007f8df2005-10-09 19:42:27 +00001527- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1528 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001529
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001530- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1531
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001532- Patch #1413711: Certain patterns of differences were making difflib
1533 touch the recursion limit.
1534
Walter Dörwald58917a62006-03-31 15:26:22 +00001535- Bug #947906: An object oriented interface has been added to the calendar
1536 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001537 called as a script (e.g. via ``python -mcalendar``). Localized month and
1538 weekday names can be ouput (even if an exotic encoding is used) using
1539 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001540

1543
Neal Norwitz602d3392006-03-31 08:21:40 +00001544- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1545 by using -mieee gcc option.
1546
Martin v. Löwis86d66262006-02-17 08:40:11 +00001547- Patch #1432345: Make python compile on DragonFly.
1548
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001549- Build support for Win64-AMD64 was added.
1550
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001551- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1552
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001553- Patch #881820: look for openpty and forkpty also in libbsd.
1554
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001555- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1556 The zlib module is now builtin on Windows.
1557
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001558- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1559
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001560- Bug #1189330: configure did not correctly determine the necessary
1561 value of LINKCC if python was built with GCC 4.0.
1562
Trent Mick8321b422005-07-26 02:29:21 +00001563- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1564 vulnerability in zlib 1.2.1 and 1.2.2.
1565
Brett Cannon08cd5982005-04-24 22:26:38 +00001566- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1567 flags that change binary compatibility. Changes were also made to
1568 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001569 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001570
Bob Ippolitoed233462005-03-29 13:47:59 +00001571- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1572 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1573 no longer exists). This configure patch makes things right.
1574
Martin v. Löwise2713be2005-03-08 15:03:08 +00001575- Bug #1158607: Build with --disable-unicode again.
1576
Brett Cannon46d96232005-02-16 00:07:19 +00001577- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1578 defined. Discovered as a result of not being able to build on OS X.
1579
Brett Cannon516592f2004-12-07 00:42:59 +00001580- setup.py now uses the directories specified in LDFLAGS using the -L option
1581 and in CPPFLAGS using the -I option for adding library and include
1582 directories, respectively, for compiling extension modules against. This has
1583 led to the core being compiled using the values in CPPFLAGS. It also removes
1584 the need for the special-casing of both DarwinPorts and Fink for darwin since
1585 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1586 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1587 Fink, ``-I/opt/local/include`` for DarwinPorts).
1588
Brett Cannon43802422005-02-10 20:48:03 +00001589- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1590 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1591 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1592 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001594C API
1595-----
1596
Tim Petersc9d78aa2006-03-26 23:27:58 +00001597- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1598 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1599 is obtained via the ``PyObject_`` family, it must be released via the
1600 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1601 always been officially true, but when Python's small-object allocator was
1602 introduced, an attempt was made to cater to a few extension modules
1603 discovered at the time that obtained memory via ``PyObject_New`` but
1604 released it via ``PyMem_DEL``. It's years later, and if such code still
1605 exists it will fail now (probably with segfaults, but calling wrong
1606 low-level memory management functions can yield many symptoms).
1607
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001608- Added a C API for set and frozenset objects.
1609
Raymond Hettinger66517482004-12-03 11:45:13 +00001610- Removed PyRange_New().
1611
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001612- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1613 mapping argument now. This string is used as a mapping table. Byte values
1614 greater than the length of the string and 0xFFFE are treated as undefined
1615 mappings.
