297 - iso2022_jp_2 codec now encodes into G0 for KS X 1001, GB2312
298 codepoints to conform the standard.
Hye-Shik Chang2cad3e92006-09-05 12:14:57 +0000299 - iso2022_jp_3 and iso2022_jp_2004 codec can encode JIS X 0213:2
Hye-Shik Chang199f1db2006-09-05 12:07:09 +0000300 codepoints now.

Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000302- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
303 mode by only placing a timeout on the select() if an input hook has
304 been defined. This prevents an interactive Python from waking up 10
305 times per second. Patch by Richard Boulton.

Brett Cannon6d9520c2006-12-13 23:09:53 +0000311- Added guard_warnings_filter to test.test_support. It returns a context
312 manager that protects the 'warnings' module's filter from being mutated
313 once the context has been exited.

399
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000400- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000401 compared equal or unequal to a string and a UnicodeDecodeError
402 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000403
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000404 Instead, the equal (==) and unequal (!=) comparison operators will
405 now issue a UnicodeWarning and interpret the two objects as
406 unequal. The UnicodeWarning can be filtered as desired using
407 the warning framework, e.g. silenced completely, turned into an
408 exception, logged, etc.
409
410 Note that compare operators other than equal and unequal will still
411 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000412
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000413- Fix segfault when doing string formatting on subclasses of long.
414
415- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
416 with new-style classes.
417
418- Fix bug related to __len__ functions returning negative values with
419 classic classes.
420
421- Patch #1538606, Fix __index__() clipping. There were some problems
422 discovered with the API and how integers that didn't fit into Py_ssize_t
423 were handled. This patch attempts to provide enough alternatives
424 to effectively use __index__.
425
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000426- Bug #1536021: __hash__ may now return long int; the final hash
427 value is obtained by invoking hash on the long int.
428
Thomas Hellerab1049c2006-08-08 17:37:00 +0000429- Bug #1536786: buffer comparison could emit a RuntimeWarning.
430
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000431- Bug #1535165: fixed a segfault in input() and raw_input() when
432 sys.stdin is closed.
433
Thomas Heller74d36f02006-08-04 18:17:40 +0000434- On Windows, the PyErr_Warn function is now exported from
435 the Python dll again.
436
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000437- Bug #1191458: tracing over for loops now produces a line event
438 on each iteration. Fixing this problem required changing the .pyc
439 magic number. This means that .pyc files generated before 2.5c1
440 will be regenerated.
441
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000442- Bug #1333982: string/number constants were inappropriately stored
443 in the byte code and co_consts even if they were not used, ie
444 immediately popped off the stack.
445
Georg Brandle9462c72006-08-04 18:03:37 +0000446- Fixed a reference-counting problem in property().

449Library
450-------
451
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000452- Fix a bug in the ``compiler`` package that caused invalid code to be
453 generated for generator expressions.
454
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000455- The distutils version has been changed to 2.5.0. The change to
456 keep it programmatically in sync with the Python version running
457 the code (introduced in 2.5b3) has been reverted. It will continue
458 to be maintained manually as static string literal.
459
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000460- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000461 and this cannot be converted to the required C type, an exception is
462 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000463 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000464
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000465- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000466 an exception.
467
Tim Petersc10c9d02006-09-05 02:18:09 +0000468- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000469 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000470 workarounds for clocks with low resolution, to stop the code yielding
471 duplicate UUIDs.
472
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000473- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
474 before raising SystemExit, allowing IDLE to honor quit() and exit().
475
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000476- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
477
Georg Brandl7a1af772006-08-14 21:55:28 +0000478- Patch #1536071: trace.py should now find the full module name of a
479 file correctly even on Windows.
480
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000481- logging's atexit hook now runs even if the rest of the module has
482 already been cleaned up.
483
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000484- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000485
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000486- Bug #1531405, format_exception no longer raises an exception if
487 str(exception) raised an exception.
488
Neil Schemenauer06ded092006-08-04 16:20:30 +0000489- Fix a bug in the ``compiler`` package that caused invalid code to be
490 generated for nested functions.

499 raises the correct exceptions.
500
Thomas Heller1ce433e2006-08-14 16:20:04 +0000501- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
502 '-no-stack-protector' compiler flag for OpenBSD has been removed.
503
Thomas Heller86720042006-08-14 11:17:48 +0000504- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
505 uses the _as_parameter_ attribute when objects are passed to foreign
506 function calls. The ctypes version number was changed to 1.0.1.
507
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000508- Bug #1530559, struct.pack raises TypeError where it used to convert.
509 Passing float arguments to struct.pack when integers are expected
510 now triggers a DeprecationWarning.

560Core and builtins
561-----------------
562
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000563- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000564 returned a long (see PEP 353).
565
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000566- Bug #1515471: string.replace() accepts character buffers again.
567
Neal Norwitz07aadb12006-07-30 06:55:48 +0000568- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
569 This provides the proper warning for struct.pack().
570 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
571
Neal Norwitz0d62a062006-07-30 06:53:31 +0000572- Patch #1531113: Fix augmented assignment with yield expressions.
573 Also fix a SystemError when trying to assign to yield expressions.
574
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000575- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
576 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
577 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
578 excessive filesystem operations during imports.
579
Tim Petersbc24eee2006-07-27 01:14:53 +0000580- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
581 operations on signed longs that are formally undefined by C.
582 Unfortunately, at least one compiler now cares about that, so complicated
583 the code to make that compiler happy again.
584
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000585- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Neal Norwitz84be93b2006-07-16 01:50:38 +0000594- Bug #1512814, Fix incorrect lineno's when code within a function
595 had more than 255 blank lines.
596
Georg Brandl9dceedb2006-07-12 15:31:17 +0000597- Patch #1521179: Python now accepts the standard options ``--help`` and
598 ``--version`` as well as ``/?`` on Windows.
599
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000600- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000601 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000602 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +0000604- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000605 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000606 new ``sys._current_frames()`` returns a dictionary with one entry,
607 mapping the faux "thread id" 0 to the current frame.

613-------
614
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000615- Correction of patch #1455898: In the mbcs decoder, set final=False
616 for stream decoder, but final=True for the decode function.
617
Georg Brandl07fec3a2006-08-01 18:49:24 +0000618- os.urandom no longer masks unrelated exceptions like SystemExit or
619 KeyboardInterrupt.
620
Tim Peters4643c2f2006-08-10 22:45:34 +0000621- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000622 shutil.copytree on Windows
623
Georg Brandle34ac7c2006-07-30 11:07:23 +0000624- Bug #1002398: The documentation for os.path.sameopenfile now correctly
625 refers to file descriptors, not file objects.
626
Tim Petersc10c9d02006-09-05 02:18:09 +0000627- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000628 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000629 #1513611, and probably others.
630
Georg Brandledd9b0d2006-07-29 09:33:26 +0000631- Bug #1441397: The compiler module now recognizes module and function
632 docstrings correctly as it did in Python 2.4.
633
Tim Peters6f681472006-07-27 23:44:37 +0000634- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
635 lost that tests are sorted by name before being run. This rarely
636 matters for well-written tests, but can create baffling symptoms if
637 side effects from one test to the next affect outcomes. ``DocTestFinder``
638 has been changed to sort the list of tests it returns.
639
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000640- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000641 in sync with sys.version_info[:3].

644
Georg Brandl8c036cc2006-08-20 13:15:39 +0000645- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
646 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000647
Georg Brandlcf0c1722006-07-26 07:23:32 +0000648- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
649 to recursive calls and call it with the failing package name.
650
Martin v. Löwis0b483032006-07-25 09:53:12 +0000651- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
652
Georg Brandlc13c34c2006-07-24 14:09:56 +0000653- Patch #1515343: Fix printing of deprecated string exceptions with a
654 value in the traceback module.
655
Greg Ward48fae7a2006-07-23 16:05:51 +0000656- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
657
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000658- Patch #1524429: Use repr() instead of backticks in Tkinter again.
659
Brett Cannoncaebe222006-07-18 04:41:36 +0000660- Bug #1520914: Change time.strftime() to accept a zero for any position in its
661 argument tuple. For arguments where zero is illegal, the value is forced to
662 the minimum value that is correct. This is to support an undocumented but
663 common way people used to fill in inconsequential information in the time
664 tuple pre-2.4.
665
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000666- Patch #1220874: Update the binhex module for Mach-O.
667
Barry Warsawb110bad2006-07-21 14:51:07 +0000668- The email package has improved RFC 2231 support, specifically for
669 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
670 (name*0=<blah>) parameter continuations. This may change the types of
671 values returned from email.message.Message.get_param() and friends.
672 Specifically in some cases where non-encoded continuations were used,
673 get_param() used to return a 3-tuple of (None, None, string) whereas now it
674 will just return the string (since non-encoded continuations don't have
675 charset and language parts).
676
677 Also, whereas % values were decoded in all parameter continuations, they are
678 now only decoded in encoded parameter parts.
679
Ronald Oussoren3075e162006-07-25 20:28:55 +0000680- Bug #1517990: IDLE keybindings on MacOS X now work correctly
681
682- Bug #1517996: IDLE now longer shows the default Tk menu when a
683 path browser, class browser or debugger is the frontmost window on MacOS X
684
Barry Warsaw00decd72006-07-27 23:43:15 +0000685- Patch #1520294: Support for getset and member descriptors in types.py,
686 inspect.py, and pydoc.py. Specifically, this allows for querying the type
687 of an object against these built-in types and more importantly, for getting
688 their docstrings printed in the interactive interpreter's help() function.

693
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000694- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
695 a socket operation on a socket with a timeout, the exception will be
696 caught correctly. Previously, the exception was not caught.
697
Thomas Heller1393d6a2006-07-28 21:43:20 +0000698- Patch #1529514: The _ctypes extension is now compiled on more
699 openbsd target platforms.
700
Tim Peters9cab5932006-07-28 00:30:00 +0000701- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
702 a memory leak, affecting pickles and deep copies.
703
Tim Petersbc24eee2006-07-27 01:14:53 +0000704- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

706
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000707- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
708
Thomas Hellerce049a02006-07-14 17:51:14 +0000709- Patch #1521817: Index range checking on ctypes arrays containing
710 exactly one element enabled again. This allows iterating over these
711 arrays, without the need to check the array size before.
712
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000713- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000714 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000715 /dev/null in certain cases; this is now fixed.
716
Thomas Heller47d7a062006-07-12 08:43:47 +0000717- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
718 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000719
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000720- Because of a misspelled preprocessor symbol, ctypes was always
721 compiled without thread support; this is now fixed.
722
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000723- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
724 methods now allow their database parameter to be None as the
725 sleepycat API allows.
726
Matt Flemingec926502006-07-28 11:27:27 +0000727- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
728 bluetooth API compared with Linux and FreeBSD.
729
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000730Tests
731-----
732
733- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
734 how long the test file should take to play. Now accepts taking 2.93 secs
735 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
736
Georg Brandl4793aa32006-07-28 18:31:39 +0000737- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
738 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
739 run via ``regrtest.py``. Now they do.

748
749- PythonLauncher now works correctly when the path to the script contains
750 characters that are treated specially by the shell (such as quotes).
751
752- Bug #1527397: PythonLauncher now launches scripts with the working directory
753 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000754 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000755 expect.

764-----------------
765
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000766- Bug #1441486: The literal representation of -(sys.maxint - 1)
767 again evaluates to a int object, not a long.
768
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000769- Bug #1501934: The scope of global variables that are locally assigned
770 using augmented assignment is now correctly determined.
771
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000772- Bug #927248: Recursive method-wrapper objects can now safely
773 be released.
774
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000775- Bug #1417699: Reject locale-specific decimal point in float()
776 and atof().
777
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000778- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
779 omit a default "error" argument for NULL pointer. This allows
780 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000781
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000782- Bug #1519018: 'as' is now validated properly in import statements.
783
Neal Norwitz28746ab2006-07-09 22:14:42 +0000784- On 64 bit systems, int literals that use less than 64 bits are
785 now ints rather than longs.
786
Neal Norwitzed657552006-07-10 00:04:44 +0000787- Bug #1512814, Fix incorrect lineno's when code at module scope
788 started after line 256.
789
Tim Peters32a83612006-07-10 21:08:24 +0000790- New function ``sys._current_frames()`` returns a dict mapping thread
791 id to topmost thread stack frame. This is for expert use, and is
792 especially useful for debugging application deadlocks. The functionality
793 was previously available in Fazal Majid's ``threadframe`` extension
794 module, but it wasn't possible to do this in a wholly threadsafe way from
795 an extension.

812
Thomas Woutersadd19112006-07-05 11:03:49 +0000813- string.Template() now correctly handles tuple-values. Previously,
814 multi-value tuples would raise an exception and single-value tuples would
815 be treated as the value they contain, instead.

836 attribute values.
837
838- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
839 sgmllib ('[' and ']' were not accepted).

Georg Brandl1be63af2006-06-28 20:23:25 +0000841- Fix a bug in the turtle module's end_fill function.
842
Brett Cannon53ab5b72006-06-22 16:49:14 +0000843- Bug #1510580: The 'warnings' module improperly required that a Warning
844 category be either a types.ClassType and a subclass of Warning. The proper
845 check is just that it is a subclass with Warning as the documentation states.
846
Georg Brandlad29e632006-06-21 17:45:17 +0000847- The compiler module now correctly compiles the new try-except-finally
848 statement (bug #1509132).
849
Neal Norwitz60373cd2006-06-22 06:30:50 +0000850- The wsgiref package is now installed properly on Unix.
851
Vinay Sajip28e57612006-07-01 10:45:20 +0000852- A bug was fixed in logging.config.fileConfig() which caused a crash on
853 shutdown when fileConfig() was called multiple times.
854
Gerhard Häring762fbd32006-07-02 17:48:30 +0000855- The sqlite3 module did cut off data from the SQLite database at the first
856 null character before sending it to a custom converter. This has been fixed
857 now.

Tim Peters112aad32006-07-19 00:03:19 +0000862- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
863 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
864 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000865
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000866- Assigning None to pointer type fields in ctypes structures possible
867 overwrote the wrong fields, this is fixed now.
868
869- Fixed a segfault in _ctypes when ctypes.wintypes were imported
870 on non-Windows platforms.
871
872- Bug #1518190: The ctypes.c_void_p constructor now accepts any
873 integer or long, without range checking.
874
875- Patch #1517790: It is now possible to use custom objects in the ctypes
876 foreign function argtypes sequence as long as they provide a from_param
877 method, no longer is it required that the object is a ctypes type.
878
879- The '_ctypes' extension module now works when Python is configured
880 with the --without-threads option.
881
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000882- Bug #1513646: os.access on Windows now correctly determines write
883 access, again.
884
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000885- Bug #1512695: cPickle.loads could crash if it was interrupted with

897
Tim Peters32a83612006-07-10 21:08:24 +0000898- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000899 Previously, the slight difference could cause compilation errors of the
900 'zlib' module on systems with more than one version of zlib.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000932
933Core and builtins
934-----------------
935
Georg Brandla56b9152006-06-19 06:35:54 +0000936- Patch #1507676: Error messages returned by invalid abstract object operations
937 (such as iterating over an integer) have been improved and now include the
938 type of the offending object to help with debugging.
939
Brett Cannonea3912b2006-06-13 21:46:41 +0000940- Bug #992017: A classic class that defined a __coerce__() method that returned
941 its arguments swapped would infinitely recurse and segfault the interpreter.
942
Neal Norwitz909eb122006-06-12 02:13:21 +0000943- Fix the socket tests so they can be run concurrently.
944
Neal Norwitzb9845e72006-06-12 02:11:18 +0000945- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000946 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000947
Brett Cannon22565aa2006-06-09 22:31:23 +0000948- Bug #532646: object.__call__() will continue looking for the __call__
949 attribute on objects until one without one is found. This leads to recursion
950 when you take a class and set its __call__ attribute to an instance of the
951 class. Originally fixed for classic classes, but this fix is for new-style.
952 Removes the infinite_rec_3 crasher.
953
Georg Brandl24250812006-06-09 18:45:48 +0000954- The string and unicode methods startswith() and endswith() now accept
955 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
956
Brett Cannonde3b0522006-06-08 17:00:45 +0000957- Buffer objects, at the C level, never used the char buffer
958 implementation even when the char buffer for the wrapped object was
959 explicitly requested (originally returned the read or write buffer).
960 Now a TypeError is raised if the char buffer is not present but is
961 requested.
962
Georg Brandlddbaa662006-06-04 21:56:52 +0000963- Patch #1346214: Statements like "if 0: suite" are now again optimized
964 away like they were in Python 2.4.
965
Georg Brandlb7c8f542006-05-27 12:30:25 +0000966- Builtin exceptions are now full-blown new-style classes instead of
967 instances pretending to be classes, which speeds up exception handling
968 by about 80% in comparison to 2.5a2.
969
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000970- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
971 Unicode 4.1.
972
Georg Brandlf4ef1162006-05-26 18:03:31 +0000973- Patch #921466: sys.path_importer_cache is now used to cache valid and
974 invalid file paths for the built-in import machinery which leads to
975 fewer open calls on startup.
976
Tim Peters696cf432006-05-24 21:10:40 +0000977- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
978 of-2 bases. The largest speedup is for inputs with about 1000 decimal
979 digits. Conversion from non-power-of-2 bases remains quadratic-time in
980 the number of input digits (it was and remains linear-time for bases
981 2, 4, 8, 16 and 32).
982
Tim Petersb713ec22006-05-23 18:45:30 +0000983- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
984 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
985 an integer close to ``sys.maxint``. This was repaired by patch
986 #1335972, which also gives a nice speedup.
987
Richard Jonescebbefc2006-05-23 18:28:17 +0000988- Patch #1337051: reduced size of frame objects.
989
990- PyErr_NewException now accepts a tuple of base classes as its
991 "base" parameter.
992
Richard Jones7c88dcc2006-05-23 10:37:38 +0000993- Patch #876206: function call speedup by retaining allocated frame
994 objects.
995
Georg Brandl7b90e162006-05-18 07:01:27 +0000996- Bug #1462152: file() now checks more thoroughly for invalid mode
997 strings and removes a possible "U" before passing the mode to the
998 C library function.
999
Neal Norwitz1004a532006-05-15 07:17:23 +00001000- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1001
Neal Norwitz373f0a72006-05-15 07:04:36 +00001002- Bug #1487966: Fix SystemError with conditional expression in assignment
1003
Martin v. Löwis879768d2006-05-11 13:28:43 +00001004- WindowsError now has two error code attributes: errno, which carries
1005 the error values from errno.h, and winerror, which carries the error
1006 values from winerror.h. Previous versions put the winerror.h values
1007 (from GetLastError()) into the errno attribute.
1008
Martin v. Löwis77736712006-05-04 05:51:03 +00001009- Patch #1475845: Raise IndentationError for unexpected indent.
1010
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001011- Patch #1479181: split open() and file() from being aliases for each other.
1012
Tim Peters44bd9862006-06-01 13:49:23 +00001013- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1014 methods were always silently ignored by dictionaries when comparing keys.
1015 They are now passed through (except when using the C API function
1016 ``PyDict_GetItem()``, whose semantics did not change).
1017
1018- Bug #1456209: In some obscure cases it was possible for a class with a
1019 custom ``__eq__()`` method to confuse dict internals when class instances
1020 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1021 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001023Extension Modules
1024-----------------
1025
Trent Mick960a3f82006-06-28 20:30:41 +00001026- Bug #1295808: expat symbols should be namespaced in pyexpat
1027
1028- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1029
Brett Cannon6ee7d012006-06-08 16:23:04 +00001030- Change binascii.hexlify to accept a read-only buffer instead of only a char
1031 buffer and actually follow its documentation.
1032
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001033- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1034
Nick Coghlanc649ec52006-05-29 12:43:05 +00001035- Patch #1478788 (modified version): The functional extension module has
1036 been renamed to _functools and a functools Python wrapper module added.
1037 This provides a home for additional function related utilities that are
1038 not specifically about functional programming. See PEP 309.
1039
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001040- Patch #1493701: performance enhancements for struct module.
1041
Georg Brandl378d5922006-05-17 14:26:50 +00001042- Patch #1490224: time.altzone is now set correctly on Cygwin.
1043
Georg Brandl8d3342b2006-05-16 07:38:27 +00001044- Patch #1435422: zlib's compress and decompress objects now have a
1045 copy() method.
1046
Andrew MacIntyre92913322006-06-13 15:04:24 +00001047- Patch #1454481: thread stack size is now tunable at runtime for thread
1048 enabled builds on Windows and systems with Posix threads support.
1049
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001050- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1051 (up to the system limit of 32K characters).
1052
1053- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1054 As a result, these functions now raise WindowsError instead of OSError.
1055
Tim Peters7a822da2006-05-25 21:50:17 +00001056- ``time.clock()`` on Win64 should use the high-performance Windows
1057 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1058 Windows platforms).
1059
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001060- Calling Tk_Init twice is refused if the first call failed as that
1061 may deadlock.
1062
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001063- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1064 accept it without potentially using an uninitialized pointer.
1065
1066- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1067 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1068 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001069
Gregory P. Smith372b5832006-06-05 18:48:21 +00001070- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001071 [pybsddb project SF patch number 1466734]
1072
Gregory P. Smith372b5832006-06-05 18:48:21 +00001073- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1074 parameter is supplied. [SF pybsddb bug #1477863]
1075
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001076- bsddb: the __len__ method of a DB object has been fixed to return correct
1077 results. It could previously incorrectly return 0 in some cases.
1078 Fixes SF bug 1493322 (pybsddb bug 1184012).
1079
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001080- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1081 aborts the db transaction safely when a modifier callback fails.
1082 Fixes SF python patch/bug #1408584.
1083
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001084- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001085 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001086 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1087 database calls that would previously deadlock. [SF python bug #775414]
1088
Vinay Sajip28e57612006-07-01 10:45:20 +00001089- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1096
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001097- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1098 functions.
1099
Martin v. Löwis3798da02006-06-17 18:44:27 +00001100- Patch #812986: Update turtle output even if not tracing.
1101
Vinay Sajip28e57612006-07-01 10:45:20 +00001102- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001103 Tkinter.BaseWidget.
1104
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001105- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1106
Martin v. Löwis337487e2006-06-17 09:15:14 +00001107- Patch #763580: Add name and value arguments to Tkinter variable
1108 classes.
1109
Georg Brandl83cc0d02006-06-14 08:50:03 +00001110- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1111 mime.types file for determining MIME types.
1112
Georg Brandl2605ca82006-06-14 06:08:31 +00001113- Bug #1339007: Shelf objects now don't raise an exception in their
1114 __del__ method when initialization failed.
1115
Martin v. Löwisd8251432006-06-14 05:21:04 +00001116- Patch #1455898: The MBCS codec now supports the incremental mode for
1117 double-byte encodings.
1118
Tim Peters43898b42006-06-14 04:09:25 +00001119- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1120 guarantee that adjacent triples in the return list always describe
1121 non-adjacent blocks. Previously, a pair of matching blocks could end
1122 up being described by multiple adjacent triples that formed a partition
1123 of the matching pair.
1124
Greg Ward0e0c9f42006-06-11 16:24:11 +00001125- Bug #1498146: fix optparse to handle Unicode strings in option help,
1126 description, and epilog.
1127
Greg Wardd1c797e2006-06-11 14:42:41 +00001128- Bug #1366250: minor optparse documentation error.
1129
Greg Ward7f547402006-06-11 00:40:49 +00001130- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1131 clarify docs.
1132
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001133- The wsgiref package has been added to the standard library.
1134
Nick Coghlan676725d2006-06-08 13:54:49 +00001135- The functions update_wrapper() and wraps() have been added to the functools
1136 module. These make it easier to copy relevant metadata from the original
1137 function when writing wrapper functions.
1138
Tim Petersd6a9eef2006-06-05 01:48:21 +00001139- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1140 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001141
Martin v. Löwis3f767792006-06-04 19:36:28 +00001142- Patch #1359618: Speed up charmap encoder by using a trie structure
1143 for lookup.
1144
Tim Petersd609b1a2006-06-02 23:22:51 +00001145- The functions in the ``pprint`` module now sort dictionaries by key
1146 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1147 if and only if its display required more than one line, although that
1148 wasn't documented. The new behavior increases predictability; e.g.,
1149 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1150
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001151- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1152 (thanks for J. J. Lee).
1153
Georg Brandl2b330372006-05-28 20:23:12 +00001154- Patch #1496206: improve urllib2 handling of passwords with respect to
1155 default HTTP and HTTPS ports.
1156
George Yoshidaf3c65de2006-05-28 16:39:09 +00001157- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1158
Bob Ippolito7298f272006-05-23 18:43:47 +00001159- Patch #1281707: speed up gzip.readline.
1160
Georg Brandlb89316f2006-05-17 15:51:16 +00001161- Patch #1180296: Two new functions were added to the locale module:
1162 format_string() to get the effect of "format % items" but locale-aware,
1163 and currency() to format a monetary number with currency sign.
1164
Georg Brandle3a25832006-05-17 14:56:04 +00001165- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1166 and several features added, such as speed and geometry control.
1167
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001168- Patch #1488881: add support for external file objects in bz2 compressed
1169 tarfiles.
1170
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001171- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1172 stdout arguments, making it possible to redirect input and output
1173 for remote debugging.
1174
1175- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1176 a couple of issues, notably handling of long file names using the
1177 GNU LONGNAME extension.
1178
1179- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1180 new flag when ``name`` is already the name of an option flag.
1181
1182- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1183 package.
1184
1185- Patch #1472854: make the rlcompleter.Completer class usable on non-
1186 UNIX platforms.
1187
1188- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1189
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001190- Bug #1472827: correctly escape newlines and tabs in attribute values in
1191 the saxutils.XMLGenerator class.

Georg Brandl66a0dbb2006-06-08 12:54:13 +00001197- Bug #1502728: Correctly link against librt library on HP-UX.
1198
Martin v. Löwis222c5152006-06-03 07:37:13 +00001199- OpenBSD 3.9 is supported now.
1200

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001221What's New in Python 2.5 alpha 2?
1222=================================
1223
1224*Release date: 27-APR-2006*
1225
1226Core and builtins
1227-----------------
1228
Thomas Heller1b046642006-04-18 18:51:06 +00001229- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1230 by converting these apis from macros into exported functions again:
1231
1232 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1233 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1234 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1235 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1236 PyRun_String Py_CompileString
1237
Martin v. Löwis45294a92006-04-18 06:24:08 +00001238- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1239
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001240- All uses of PyStructSequence_InitType have been changed to initialize
1241 the type objects only once, even if the interpreter is initialized
1242 multiple times.
1243
Neal Norwitz61546162006-04-14 05:20:28 +00001244- Bug #1454485, array.array('u') could crash the interpreter. This was
1245 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1246 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1247
1248- Py_UNICODE is unsigned. It was always documented as unsigned, but
1249 due to a bug had a signed value in previous versions.
1250
Tim Peters3a5e8b12006-04-11 01:44:07 +00001251- Patch #837242: ``id()`` of any Python object always gives a positive
1252 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1253 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001254 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001255 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001256
Tim Peters3a5e8b12006-04-11 01:44:07 +00001257 def __hash__(self):
1258 return id(self) # WRONG
1259
1260 because a hash result must be a (short) Python int but it was always
1261 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001262 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001263 was always usable as a hash value before this patch. That's no longer
1264 necessarily so.
1265
1266- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001267 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001268 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001269 #1454844)
1270
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001271- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1272 involving generators that have paused outside of any ``try`` or ``with``
1273 blocks. (In 2.5a1, a paused generator that was part of a reference
1274 cycle could not be garbage collected, regardless of whether it was
1275 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001276
Anthony Baxter51bcb682006-04-05 14:51:42 +00001277Extension Modules
1278-----------------
1279
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001280- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1281 is a macro.
1282
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001283- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1284 fails with an error condition.
1285
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001286- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1287
1288- Bug #1117761: bsddb.*open() no longer raises an exception when using
1289 the cachesize parameter.
1290
1291- Bug #1149413: bsddb.*open() no longer raises an exception when using
1292 a temporary db (file=None) with the 'n' flag to truncate on open.
1293
1294- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1295 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001296
Armin Rigoa9017c32006-04-19 11:50:27 +00001297- Patch #1062014: AF_UNIX sockets under Linux have a special
1298 abstract namespace that is now fully supported.
1299
Anthony Baxter51bcb682006-04-05 14:51:42 +00001300Library
1301-------
1302
Peter Astrand7d1d4362006-07-14 14:04:45 +00001303- Bug #1223937: subprocess.CalledProcessError reports the exit status
1304 of the process using the returncode attribute, instead of
1305 abusing errno.
1306
Tim Peters711bf302006-04-25 03:31:36 +00001307- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1308 a doctest to be skipped (the code is not run, and the expected output
1309 or exception is ignored).
1310
Nick Coghlanda2268f2006-04-24 04:37:15 +00001311- Fixed contextlib.nested to cope with exceptions being raised and
1312 caught inside exit handlers.
1313
Greg Wardab05edc2006-04-23 03:47:58 +00001314- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1315 hex, octal, or binary; add ``append_const`` action; keep going if
1316 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1317 added ``epilog`` for better help generation).
1318
Tim Peters21fbd572006-04-21 21:18:10 +00001319- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1320 called from a thread spawned as a side effect of importing a module.
1321
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001322- The pydoc module now supports documenting packages contained in
1323 .zip or .egg files.
1324
1325- The pkgutil module now has several new utility functions, such
1326 as ``walk_packages()`` to support working with packages that are either
1327 in the filesystem or zip files.
1328
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001329- The mailbox module can now modify and delete messages from
1330 mailboxes, in addition to simply reading them. Thanks to Gregory
1331 K. Johnson for writing the code, and to the 2005 Google Summer of
1332 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001333
Tim Petersc7605f22006-04-17 21:12:33 +00001334- The ``__del__`` method of class ``local`` in module ``_threading_local``
1335 returned before accomplishing any of its intended cleanup.
1336
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001337- Patch #790710: Add breakpoint command lists in pdb.
1338
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001339- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1340
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001341- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1342
Anthony Baxtere29002c2006-04-12 12:07:31 +00001343- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1344 Windows. Bug #1469163.
1345
Phillip J. Eby47032112006-04-11 01:07:43 +00001346- The warnings, linecache, inspect, traceback, site, and doctest modules
1347 were updated to work correctly with modules imported from zipfiles or
1348 via other PEP 302 __loader__ objects.
1349
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001350- Patch #1467770: Reduce usage of subprocess._active to processes which
1351 the application hasn't waited on.
1352
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001353- Patch #1462222: Fix Tix.Grid.
1354
Neal Norwitza31bf182006-04-09 03:35:43 +00001355- Fix exception when doing glob.glob('anything*/')
1356
Skip Montanaro262fb922006-04-21 02:31:07 +00001357- The pstats.Stats class accepts an optional stream keyword argument to
1358 direct output to an alternate file-like object.
1359
Anthony Baxter51bcb682006-04-05 14:51:42 +00001360Build
1361-----
1362
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001363- The Makefile now has a reindent target, which runs reindent.py on
1364 the library.
1365
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001366- Patch #1470875: Building Python with MS Free Compiler
1367
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001368- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001369
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001370- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1371 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001372 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001373 CXX from --with-cxx-main, see description in README.
1374
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001375- Patch #1429775: Link extension modules with the shared libpython.
1376
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001377- Fixed a libffi build problem on MIPS systems.
1378
Tim Peters8931ff12006-05-13 23:28:20 +00001379- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1380 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1381 and "%zu" for unsigned integers of type ``size_t``.
1382
Anthony Baxter51bcb682006-04-05 14:51:42 +00001383Tests
1384-----
1385
Nick Coghlanda2268f2006-04-24 04:37:15 +00001386- test_contextlib now checks contextlib.nested can cope with exceptions
1387 being raised and caught inside exit handlers.
1388
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001389- test_cmd_line now checks operation of the -m and -c command switches
1390
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001391- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1392 it separately and by hand. It also wasn't cleaning up its changes to
1393 the current Decimal context.
1394
Thomas Woutersabd08882006-04-26 15:53:30 +00001395- regrtest.py now has a -M option to run tests that test the new limits of
1396 containers, on 64-bit architectures. Running these tests is only sensible
1397 on 64-bit machines with more than two gigabytes of memory. The argument
1398 passed is the maximum amount of memory for the tests to use.
1399
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001400Tools
1401-----
1402
1403- Added the Python benchmark suite pybench to the Tools/ directory;
1404 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001405
Anthony Baxter51bcb682006-04-05 14:51:42 +00001406Documentation
1407-------------
1408
Tim Petersb06d28c2006-05-12 01:57:59 +00001409- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1410
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001411- PEP 343: Added Context Types section to the library reference
1412 and attempted to bring other PEP 343 related documentation into
1413 line with the implementation and/or python-dev discussions.
1414
Tim Peters8dc73d22006-04-24 02:03:16 +00001415- Bug #1337990: clarified that ``doctest`` does not support examples
1416 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001417

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001419What's New in Python 2.5 alpha 1?
1420=================================
1421
Anthony Baxterebed3f62006-04-03 15:03:44 +00001422*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001423
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001424Core and builtins
1425-----------------
1426
Nick Coghlan43832302006-04-23 17:04:07 +00001427- PEP 338: -m command line switch now delegates to runpy.run_module
1428 allowing it to support modules in packages and zipfiles
1429
Martin v. Löwisc661b882006-04-20 04:54:23 +00001430- On Windows, .DLL is not an accepted file name extension for
1431 extension modules anymore; extensions are only found if they
1432 end in .PYD.
1433
Martin v. Löwisea62d252006-04-03 10:56:49 +00001434- Bug #1421664: sys.stderr.encoding is now set to the same value as
1435 sys.stdout.encoding.
1436
Neal Norwitz92e212f2006-04-03 04:48:37 +00001437- __import__ accepts keyword arguments.
1438
Georg Brandlccadf842006-03-31 18:54:53 +00001439- Patch #1460496: round() now accepts keyword arguments.
1440
Anthony Baxter262c00a2006-03-30 10:53:17 +00001441- Fixed bug #1459029 - unicode reprs were double-escaped.
1442
Hye-Shik Changd478f342006-03-23 12:32:36 +00001443- Patch #1396919: The system scope threads are reenabled on FreeBSD
1444 5.4 and later versions.
1445
Neal Norwitze98ccf62006-03-23 05:39:47 +00001446- Bug #1115379: Compiling a Unicode string with an encoding declaration
1447 now gives a SyntaxError.
1448
Georg Brandlabd1ff82006-03-18 07:59:59 +00001449- Previously, Python code had no easy way to access the contents of a
1450 cell object. Now, a ``cell_contents`` attribute has been added
1451 (closes patch #1170323).
1452
Tim Peterscf79aac2006-03-16 01:14:46 +00001453- Patch #1123430: Python's small-object allocator now returns an arena to
1454 the system ``free()`` when all memory within an arena becomes unused
1455 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1456 freed. Some applications will see a drop in virtual memory size now,
1457 especially long-running applications that, from time to time, temporarily
1458 use a large number of small objects. Note that when Python returns an
1459 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001460 platform C library will in turn return that memory to the operating system.
1461 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001462 appears to be effective at least on Microsoft C and gcc-based systems.
1463 Thanks to Evan Jones for hard work and patience.
1464
Georg Brandl533ff6f2006-03-08 18:09:27 +00001465- Patch #1434038: property() now uses the getter's docstring if there is
1466 no "doc" argument given. This makes it possible to legitimately use
1467 property() as a decorator to produce a read-only property.
1468
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001469- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1470 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1471 of requiring an int or long in slicing and a few other contexts, enabling
1472 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1473
Neal Norwitz995acdf2006-03-07 05:01:00 +00001474- Fixed various bugs reported by Coverity's Prevent tool.
1475
Brett Cannonbf364092006-03-01 04:25:17 +00001476- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1477 new exception base class, BaseException, which has a new message attribute.
1478 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1479 Raising a string exception now raises a DeprecationWarning.
1480
Thomas Woutersfb609f42006-02-28 16:37:25 +00001481- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1482 explicitly relative, using 'from .module import name' to mean 'from the same
1483 package as this module is in. Imports without dots still default to the
1484 old relative-then-absolute, unless 'from __future__ import
1485 absolute_import' is used.
1486
Brett Cannona7446e32006-02-27 23:39:10 +00001487- Properly check if 'warnings' raises an exception (usually when a filter set
1488 to "error" is triggered) when raising a warning for raising string
1489 exceptions.
1490
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001491- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001492 The name was removed from Include/code.h.
1493
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001494- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001495
Guido van Rossum1968ad32006-02-25 22:38:04 +00001496- Patch 1433928:
1497 - The copy module now "copies" function objects (as atomic objects).
1498 - dict.__getitem__ now looks for a __missing__ hook before raising
1499 KeyError.

Tim Peters84ef21c2006-02-28 20:39:06 +00001501- PEP 343: with statement implemented. Needs ``from __future__ import
1502 with_statement``. Use of 'with' as a variable will generate a warning.
1503 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001504 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001505 The following objects have __context__ methods:
1506 - The built-in file type.
1507 - The thread.LockType type.
1508 - The following types defined by the threading module:
1509 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1510 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001511
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001512- Fix the encodings package codec search function to only search
1513 inside its own package. Fixes problem reported in patch #1433198.
1514
1515 Note: Codec packages should implement and register their own
1516 codec search function. PEP 100 has the details.
1517
Tim Peters9ea89d22006-06-04 03:26:02 +00001518- PEP 353: Using ``Py_ssize_t`` as the index type.
1519
1520- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1521 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1522 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1523 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1524 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001525
Neal Norwitzfc76d632006-01-10 06:03:13 +00001526- Patch #1400181, fix unicode string formatting to not use the locale.
1527 This is how string objects work. u'%f' could use , instead of .
1528 for the decimal point. Now both strings and unicode always use periods.
1529
Neal Norwitz671b9e32006-01-09 07:07:12 +00001530- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1531 configure would break checking curses.h.
1532
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001533- Bug #959576: The pwd module is now builtin. This allows Python to be
1534 built on UNIX platforms without $HOME set.
1535
Neal Norwitzc10978f2005-12-19 06:07:16 +00001536- Bug #1072182, fix some potential problems if characters are signed.
1537
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001538- Bug #889500, fix line number on SyntaxWarning for global declarations.
1539
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001540- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1541
Neal Norwitze7214a12005-12-18 05:03:17 +00001542- Support for converting hex strings to floats no longer works.
1543 This was not portable. float('0x3') now raises a ValueError.
1544
Barry Warsaw2a38a862005-12-18 01:27:35 +00001545- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001546 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001547 is now displayed in interactive prompt banner.
1548
Georg Brandlfa166682005-12-17 21:45:17 +00001549- Implementation of PEP 341 - Unification of try/except and try/finally.
1550 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001551 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001552
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001553- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1554 now encodes backslash correctly.
1555
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001556- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1557
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001558- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001559 and long longs.
1560
Neal Norwitz67715f02005-11-09 06:59:35 +00001561- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001562 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001563 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001564
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001565- Replaced most Unicode charmap codecs with new ones using the
1566 new Unicode translate string feature in the builtin charmap
1567 codec; the codecs were created from the mapping tables available
1568 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1569 encodings now include a mapping for the Apple logo)
1570
Tim Peterse3547fd2005-12-16 23:13:57 +00001571- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001572
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001573- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001574
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001575- A new AST parser implementation was completed. The abstract
1576 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001577 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001578
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001579- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001580 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1581
Neal Norwitz708e51a2005-10-03 04:48:15 +00001582- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1583
Neal Norwitz11bd1192005-10-03 00:54:56 +00001584- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1585 Provide a warning when a directory is passed on the command line.
1586
Neal Norwitz40d37812005-10-02 01:48:49 +00001587- Fix segfault with invalid coding.
1588
1589- SF bug #772896: unknown encoding results in MemoryError.
1590
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001591- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001592 supported a __len__() method which evaluated to False when the iterator
1593 was empty.
1594
Guido van Rossum630db602005-09-20 18:49:54 +00001595- On 64-bit platforms, when __len__() returns a value that cannot be
1596 represented as a C int, raise OverflowError.
1597
Skip Montanarof8948ca2005-09-19 03:54:46 +00001598- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001599 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001600
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001601- SF bug #893549: parsing keyword arguments was broken with a few format
1602 codes.
1603
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001604- Changes donated by Elemental Security to make it work on AIX 5.3
1605 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1606 bug #105470: test_pwd fails on 64bit system (Opteron).
1607
Guido van Rossum539c6622005-09-14 17:49:54 +00001608- Changes donated by Elemental Security to make it work on HP-UX 11 on
1609 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1610
Georg Brandl4550b8d2005-08-26 06:43:52 +00001611- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001612 (fixes bug #1119418).
1613
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001614- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1615
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001616- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1617 exceptions that cause a function to exit.
1618
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001619- The implementation of set() and frozenset() was revised to use its
1620 own internal data structure. Memory consumption is reduced by 1/3
1621 and there are modest speed-ups as well. The API is unchanged.
1622
Tim Petersde7990b2005-07-17 23:45:23 +00001623- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1624
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001625- SF bug #1229429: PyObject_CallMethod failed to decrement some
1626 reference counts in some error exit cases.
1627
Tim Petersecc6e6a2005-07-10 22:30:55 +00001628- SF bug #1185883: Python's small-object memory allocator took over
1629 a block managed by the platform C library whenever a realloc specified
1630 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001631 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001632 portable way to copy data from the C-managed block into Python's
1633 small-object space without risking a memory fault. Python's small-object
1634 realloc now leaves such blocks under the control of the platform C
1635 realloc.
1636
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001637- SF bug #1232517: An overflow error was not detected properly when
1638 attempting to convert a large float to an int in os.utime().
1639
Raymond Hettinger3296e692005-06-29 23:29:56 +00001640- SF bug #1224347: hex longs now print with lowercase letters just
1641 like their int counterparts.
1642
Michael W. Hudson188d4362005-06-20 16:52:57 +00001643- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1644 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1645 interpreter states; back out that fix and do a better job (see
1646 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1647 for a longer write-up of the problem).
1648
Michael W. Hudsondf888462005-06-03 14:41:55 +00001649- SF patch #1180995: marshal now uses a binary format by default when
1650 serializing floats.
1651
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001652- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1653 the routines that promise to produce IEEE 754 binary representations
1654 of floats now simply copy bytes around.
1655
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001656- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1657 278.
1658
Brett Cannonc3647ac2005-04-26 03:45:26 +00001659- patch #1109424: int, long, float, complex, and unicode now check for the
1660 proper magic slot for type conversions when subclassed. Previously the
1661 magic slot was ignored during conversion. Semantics now match the way
1662 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001663 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001664 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001665 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001666
Barry Warsawc8d907c2005-04-19 23:43:40 +00001667- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1668 NULL, now raise an AttributeError when attempting to set or delete the
1669 attribute. Previously a TypeError was raised, but this was inconsistent
1670 with the equivalent pure-Python implementation.
1671
Michael W. Hudson774479c2005-04-18 08:46:17 +00001672- It is now safe to call PyGILState_Release() before
1673 PyEval_InitThreads() (note that if there is reason to believe there
1674 are multiple threads around you still must call PyEval_InitThreads()
1675 before using the Python API; this fix is for extension modules that
1676 have no way of knowing if Python is multi-threaded yet).
1677
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001678- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1679 disabled caused a crash.
1680
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001681- Bug #1165306: instancemethod_new allowed the creation of a method
1682 with im_class == im_self == NULL, which caused a crash when called.
1683
Tim Petersecc6e6a2005-07-10 22:30:55 +00001684- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001685 fixes the crash seen in bug #1165761
1686
Raymond Hettinger96229b12005-03-11 06:49:40 +00001687- Added two new builtins, any() and all().
1688
Brett Cannon409d8f22005-03-05 06:47:57 +00001689- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001690 (e.g., ``class C(): pass`` is no longer a syntax error).
1691 Patch #1176012 added support to the 'parser' module and 'compiler' package
1692 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001693
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001694- Patch #1115086: Support PY_LONGLONG in structmember.
1695
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001696- Bug #1155938: new style classes did not check that __init__() was
1697 returning None.
1698
Tim Petersecc6e6a2005-07-10 22:30:55 +00001699- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001700 ('\') with a specific error message.
1701
Martin v. Löwisff232d72005-03-03 09:24:38 +00001702- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1703
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001704- Bug #1124295: the __name__ attribute of file objects was
1705 inadvertently made inaccessible in restricted mode.
1706
Tim Petersecc6e6a2005-07-10 22:30:55 +00001707- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001708 an ferror() call.
1709
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001710- min() and max() now support key= arguments with the same meaning as in
1711 list.sort().
1712
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001713- The peephole optimizer now performs simple constant folding in expressions:
1714 (2+3) --> (5).
1715
Raymond Hettingera422c342005-01-11 03:03:27 +00001716- set and frozenset objects can now be marshalled. SF #1098985.
1717
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001718- Bug #1077106: Poor argument checking could cause memory corruption
1719 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001720
Jeremy Hyltonab630502005-02-04 18:44:06 +00001721- The parser did not complain about future statements in illegal
1722 positions. It once again reports a syntax error if a future
1723 statement occurs after anything other than a doc string.
1724
Neil Schemenauercf52c072005-08-12 17:34:58 +00001725- Change the %s format specifier for str objects so that it returns a
1726 unicode instance if the argument is not an instance of basestring and
1727 calling __str__ on the argument returns a unicode instance.
1728
Tim Petersf4e69282006-02-27 17:15:31 +00001729- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1730 current thread state when the auto-GIL-state machinery knows about
1731 it (since the thread state is being deleted, continuing to remember it
1732 can't help, but can hurt if another thread happens to get created with
1733 the same thread id).
1734
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001735Extension Modules
1736-----------------
1737
Georg Brandl43f08a82006-03-31 18:01:16 +00001738- Patch #1380952: fix SSL objects timing out on consecutive read()s
1739
Neal Norwitz05a45592006-03-20 06:30:08 +00001740- Patch #1309579: wait3 and wait4 were added to the posix module.
1741
Anthony Baxterfa869072006-03-20 05:21:58 +00001742- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1743 In addition, the existing ulaw code was updated.
1744
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001745- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001746 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001747
Neal Norwitz10be10c2006-03-16 06:50:13 +00001748- Everything under lib-old was removed. This includes the following modules:
1749 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001750 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001751 util, whatsound, whrandom, zmod
1752
1753- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1754
1755- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001756 is deprecated. The undocumented re.engine variable no longer exists.
1757
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001758- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001925- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1926 been renamed to have only a single underscore prefix. This was done to
1927 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001928
Nick Coghlan43832302006-04-23 17:04:07 +00001929- PEP 338: new module runpy defines a run_module function to support
1930 executing modules which provide access to source code or a code object
1931 via the PEP 302 import mechanisms.
1932
Anthony Baxter93f5b932006-04-03 08:05:07 +00001933- The email module's parsedate_tz function now sets the daylight savings

1941 in attribute values.
1942
Anthony Baxterc51ee692006-04-01 00:57:31 +00001943- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001944 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001945 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001946 module will not be built.
1947
Tim Petersc17976e2006-04-01 00:26:53 +00001948- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1949 aren't officially supported here, and trying to use them will probably
1950 raise an exception some day. But dicts have been allowed, and "mostly
1951 worked", so support for them won't go away without warning.
1952
Georg Brandl338ef7d2006-03-31 18:42:16 +00001953- Bug #1445068: getpass.getpass() can now be given an explicit stream

1971
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001972- email 4.0 package now integrated. This is largely the same as the email 3.0
1973 package that was included in Python 2.3, except that PEP 8 module names are
1974 now used (e.g. mail.message instead of email.Message). The MIME classes
1975 have been moved to a subpackage (e.g. email.mime.text instead of
1976 email.MIMEText). The old names are still supported for now. Several
1977 deprecated Message methods have been removed and lots of bugs have been
1978 fixed. More details can be found in the email package documentation.
1979
Walter Dörwald40108c92006-03-27 08:15:44 +00001980- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1981 (a subclass of tuple) that provides incremental decoders and encoders
1982 (a way to use stateful codecs without the stream API). Python functions
1983 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1984 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1985 have been added.

1988 a ValueError instead of a StopIteration now (like file and cString.String do).
1989 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1990 called before (like file and StringIO.StringIO do).

2058
Neal Norwitz338e7862005-12-23 21:27:46 +00002059- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2060 LoadError as documented, instead of IOError. For compatibility,
2061 LoadError subclasses IOError.
2062
Brett Cannon3cbd0382005-12-16 22:49:23 +00002063- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002064 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2065 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2066 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2067 Ronald L. Rivest offered this advice for Python:
2068
2069 "The consensus of researchers in this area (at least as
2070 expressed at the NIST Hash Function Workshop 10/31/05),
2071 is that SHA-256 is a good choice for the time being, but
2072 that research should continue, and other alternatives may
2073 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002074
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002075- Added a subset of Fredrik Lundh's ElementTree package. Available

2128 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002129 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002130

2153
Georg Brandl9e43acf2005-07-04 17:16:07 +00002154- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2155 as this can cause problems with apps closing all file descriptors.

2169
Raymond Hettinger68c04532005-06-10 11:05:19 +00002170- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002171 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002172 the generate_tokens() function now accepts a callable argument that
2173 terminates by raising StopIteration.
2174

2192 instead of raising a TypeError when interacting with other types. This
2193 allows other classes to implement __radd__ style methods and have them
2194 work as expected.
2195
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002196- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002234- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2235 disables recursive traversal through instance attributes, which can
2236 be exploited in various ways.
2237
Tim Peterse3547fd2005-12-16 23:13:57 +00002238- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2252
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002253- Enhancements to the csv module:
2254
2255 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002256 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002257 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002258 + Dialect parameter parsing has been re-implemented to improve error
2259 reporting.
2260 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2261 dictates.
2262 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002263 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002264 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002265 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2266 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002267 + reader now allows \r characters to be quoted (previously it only allowed
2268 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002269 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002270 + Dialect classes passed to the module are no longer instantiated by
2271 the module before being parsed (the former validation scheme required
2272 this, but the mechanism was unreliable).
2273 + The dialect registry now contains instances of the internal
2274 C-coded dialect type, rather than references to python objects.
2275 + the internal c-coded dialect type is now immutable.
2276 + register_dialect now accepts the same keyword dialect specifications
2277 as the reader and writer, allowing the user to register dialects
2278 without first creating a dialect class.
2279 + a configurable limit to the size of parsed fields has been added -
2280 previously, an unmatched quote character could result in the entire
2281 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002282 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002283 the parser field size limit (returning the former limit). The initial
2284 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002285 + A line_num attribute has been added to the reader object, which tracks
2286 the number of lines read from the source iterator. This is not
2287 the same as the number of records returned, as records can span
2288 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002289 + reader and writer objects were not being registered with the cyclic-GC.
2290 This has been fixed.
2291
Brett Cannone6539c42005-01-08 02:43:53 +00002292- _DummyThread objects in the threading module now delete self.__block that is
2293 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2294 lock primitives tend to be limited in number and thus should not be wasted on
2295 a _DummyThread object. Fixes bug #1089632.
2296
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002297- The imghdr module now detects Exif files.
2298
Raymond Hettinger6065d322004-12-20 23:51:53 +00002299- StringIO.truncate() now correctly adjusts the size attribute.
2300 (Bug #951915).
2301
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002302- locale.py now uses an updated locale alias table (built using
2303 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2304 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002305 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002306
Raymond Hettinger3557f422004-12-07 12:02:02 +00002307- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2308
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002309- the pickle module no longer accepts the deprecated None option in the
2310 args tuple returned by __reduce__().
2311
Brett Cannon84667c02004-12-07 03:25:18 +00002312- optparse now optionally imports gettext. This allows its use in setup.py.
2313
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002314- the pickle module no longer uses the deprecated bin parameter.
2315
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002316- the shelve module no longer uses the deprecated binary parameter.
2317
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002318- the pstats module no longer uses the deprecated ignore() method.
2319
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002320- the filecmp module no longer uses the deprecated use_statcache argument.
2321
Raymond Hettinger664347b2004-12-04 21:21:53 +00002322- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2323 extended or overridden by subclasses. Formerly, the subclassed method would
2324 be ignored by the rest of the module. (Bug #1078905).
2325
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002326- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002327 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002328
Walter Dörwald36733692004-12-22 12:50:50 +00002329- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2330 once when a size argument is given. This prevents a buffer overflow in the
2331 tokenizer with very long source lines.
2332
Barry Warsaw538561e2006-01-01 21:48:54 +00002333- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2334 immediately after creating the object, without any intervening
2335 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002336
Skip Montanaro05885812005-01-16 20:48:27 +00002337- The reconvert.quote function can now emit triple-quoted strings. The
2338 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002339
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002340- ``UserString.MutableString`` now supports negative indices in
2341 ``__setitem__`` and ``__delitem__``
2342
Greg Ward40407942005-03-05 02:53:17 +00002343- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2344 correctly.
2345
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002346- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2347 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2348 character even if the user has passed a size parameter to get a proper
2349 line ending. Remove the special handling of a "\r\n" that has been split
2350 between two lines.
2351
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002352- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2353 about illegal code points. The codec now supports PEP 293 style error
2354 handlers.
2355
Walter Dörwald78a78b02005-09-01 12:04:29 +00002356- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002357 from the input stream, so that the output is a byte string in the correct
2358 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002359
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002360- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2361 considering it exactly like a '*'.
2362
Walter Dörwald007f8df2005-10-09 19:42:27 +00002363- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2364 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002365
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002366- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2367
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002368- Patch #1413711: Certain patterns of differences were making difflib
2369 touch the recursion limit.
2370
Walter Dörwald58917a62006-03-31 15:26:22 +00002371- Bug #947906: An object oriented interface has been added to the calendar
2372 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002373 called as a script (e.g. via ``python -mcalendar``). Localized month and
2374 weekday names can be ouput (even if an exotic encoding is used) using
2375 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002376
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002377Build
2378-----
2379
Neal Norwitz602d3392006-03-31 08:21:40 +00002380- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2381 by using -mieee gcc option.
2382
Martin v. Löwis86d66262006-02-17 08:40:11 +00002383- Patch #1432345: Make python compile on DragonFly.
2384
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002385- Build support for Win64-AMD64 was added.
2386
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002387- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2388
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002389- Patch #881820: look for openpty and forkpty also in libbsd.
2390
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002391- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2392 The zlib module is now builtin on Windows.
2393
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002394- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2395
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002396- Bug #1189330: configure did not correctly determine the necessary
2397 value of LINKCC if python was built with GCC 4.0.
2398
Trent Mick8321b422005-07-26 02:29:21 +00002399- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2400 vulnerability in zlib 1.2.1 and 1.2.2.
2401
Brett Cannon08cd5982005-04-24 22:26:38 +00002402- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2403 flags that change binary compatibility. Changes were also made to
2404 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002405 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002406
Bob Ippolitoed233462005-03-29 13:47:59 +00002407- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2408 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2409 no longer exists). This configure patch makes things right.
2410
Martin v. Löwise2713be2005-03-08 15:03:08 +00002411- Bug #1158607: Build with --disable-unicode again.
2412
Brett Cannon46d96232005-02-16 00:07:19 +00002413- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2414 defined. Discovered as a result of not being able to build on OS X.
2415
Brett Cannon516592f2004-12-07 00:42:59 +00002416- setup.py now uses the directories specified in LDFLAGS using the -L option
2417 and in CPPFLAGS using the -I option for adding library and include
2418 directories, respectively, for compiling extension modules against. This has
2419 led to the core being compiled using the values in CPPFLAGS. It also removes
2420 the need for the special-casing of both DarwinPorts and Fink for darwin since
2421 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2422 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2423 Fink, ``-I/opt/local/include`` for DarwinPorts).
2424
Brett Cannon43802422005-02-10 20:48:03 +00002425- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2426 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2427 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2428 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002430C API
2431-----
2432
Tim Petersc9d78aa2006-03-26 23:27:58 +00002433- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2434 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2435 is obtained via the ``PyObject_`` family, it must be released via the
2436 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2437 always been officially true, but when Python's small-object allocator was
2438 introduced, an attempt was made to cater to a few extension modules
2439 discovered at the time that obtained memory via ``PyObject_New`` but
2440 released it via ``PyMem_DEL``. It's years later, and if such code still
2441 exists it will fail now (probably with segfaults, but calling wrong
2442 low-level memory management functions can yield many symptoms).
2443
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002444- Added a C API for set and frozenset objects.
2445
Raymond Hettinger66517482004-12-03 11:45:13 +00002446- Removed PyRange_New().
2447
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002448- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2449 mapping argument now. This string is used as a mapping table. Byte values
2450 greater than the length of the string and 0xFFFE are treated as undefined
2451 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002458
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002459- Patch #1276356: New resource "urlfetch" is implemented. This enables
