392Core and builtins
393-----------------
394
Neal Norwitz24b6f202006-09-05 04:43:56 +0000395- Fix infinite recursion when subclassing long and overriding __hash__.
396
397- Fix concatenation (+=) of long strings.
398
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000399- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000400 compared equal or unequal to a string and a UnicodeDecodeError
401 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000402
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000403 Instead, the equal (==) and unequal (!=) comparison operators will
404 now issue a UnicodeWarning and interpret the two objects as
405 unequal. The UnicodeWarning can be filtered as desired using
406 the warning framework, e.g. silenced completely, turned into an
407 exception, logged, etc.
408
409 Note that compare operators other than equal and unequal will still
410 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000411
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000412- Fix segfault when doing string formatting on subclasses of long.
413
414- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
415 with new-style classes.
416
417- Fix bug related to __len__ functions returning negative values with
418 classic classes.
419
420- Patch #1538606, Fix __index__() clipping. There were some problems
421 discovered with the API and how integers that didn't fit into Py_ssize_t
422 were handled. This patch attempts to provide enough alternatives
423 to effectively use __index__.
424
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000425- Bug #1536021: __hash__ may now return long int; the final hash
426 value is obtained by invoking hash on the long int.
427
Thomas Hellerab1049c2006-08-08 17:37:00 +0000428- Bug #1536786: buffer comparison could emit a RuntimeWarning.
429
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000430- Bug #1535165: fixed a segfault in input() and raw_input() when
431 sys.stdin is closed.
432
Thomas Heller74d36f02006-08-04 18:17:40 +0000433- On Windows, the PyErr_Warn function is now exported from
434 the Python dll again.
435
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000436- Bug #1191458: tracing over for loops now produces a line event
437 on each iteration. Fixing this problem required changing the .pyc
438 magic number. This means that .pyc files generated before 2.5c1
439 will be regenerated.
440
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000441- Bug #1333982: string/number constants were inappropriately stored
442 in the byte code and co_consts even if they were not used, ie
443 immediately popped off the stack.
444
Georg Brandle9462c72006-08-04 18:03:37 +0000445- Fixed a reference-counting problem in property().

448Library
449-------
450
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000451- Fix a bug in the ``compiler`` package that caused invalid code to be
452 generated for generator expressions.
453
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000454- The distutils version has been changed to 2.5.0. The change to
455 keep it programmatically in sync with the Python version running
456 the code (introduced in 2.5b3) has been reverted. It will continue
457 to be maintained manually as static string literal.
458
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000459- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000460 and this cannot be converted to the required C type, an exception is
461 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000462 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000463
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000464- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000465 an exception.
466
Tim Peterscbdd3502006-09-05 01:47:53 +0000467- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000468 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000469 workarounds for clocks with low resolution, to stop the code yielding
470 duplicate UUIDs.
471
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000472- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
473 before raising SystemExit, allowing IDLE to honor quit() and exit().
474
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000475- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
476
Georg Brandl7a1af772006-08-14 21:55:28 +0000477- Patch #1536071: trace.py should now find the full module name of a
478 file correctly even on Windows.
479
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000480- logging's atexit hook now runs even if the rest of the module has
481 already been cleaned up.
482
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000483- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000484
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000485- Bug #1531405, format_exception no longer raises an exception if
486 str(exception) raised an exception.
487
Neil Schemenauer06ded092006-08-04 16:20:30 +0000488- Fix a bug in the ``compiler`` package that caused invalid code to be
489 generated for nested functions.

501
Thomas Heller1ce433e2006-08-14 16:20:04 +0000502- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
503 '-no-stack-protector' compiler flag for OpenBSD has been removed.
504
Thomas Heller86720042006-08-14 11:17:48 +0000505- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
506 uses the _as_parameter_ attribute when objects are passed to foreign
507 function calls. The ctypes version number was changed to 1.0.1.
508
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000509- Bug #1530559, struct.pack raises TypeError where it used to convert.
510 Passing float arguments to struct.pack when integers are expected
511 now triggers a DeprecationWarning.

561Core and builtins
562-----------------
563
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000564- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000565 returned a long (see PEP 353).
566
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000567- Bug #1515471: string.replace() accepts character buffers again.
568
Neal Norwitz07aadb12006-07-30 06:55:48 +0000569- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
570 This provides the proper warning for struct.pack().
571 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
572
Neal Norwitz0d62a062006-07-30 06:53:31 +0000573- Patch #1531113: Fix augmented assignment with yield expressions.
574 Also fix a SystemError when trying to assign to yield expressions.
575
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000576- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
577 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
578 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
579 excessive filesystem operations during imports.
580
Tim Petersbc24eee2006-07-27 01:14:53 +0000581- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
582 operations on signed longs that are formally undefined by C.
583 Unfortunately, at least one compiler now cares about that, so complicated
584 the code to make that compiler happy again.
585
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000586- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
587
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000588- Patch #1232023: Stop including current directory in search
589 path on Windows.
590
Neal Norwitze1fdb322006-07-21 05:32:28 +0000591- Fix some potential crashes found with failmalloc.
592
Neal Norwitze7563102006-07-17 01:00:16 +0000593- Fix warnings reported by Klocwork's static analysis tool.

596 had more than 255 blank lines.
597
Georg Brandl9dceedb2006-07-12 15:31:17 +0000598- Patch #1521179: Python now accepts the standard options ``--help`` and
599 ``--version`` as well as ``/?`` on Windows.
600
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000601- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000602 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000603 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000604
Tim Peters112aad32006-07-19 00:03:19 +0000605- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000606 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000607 new ``sys._current_frames()`` returns a dictionary with one entry,
608 mapping the faux "thread id" 0 to the current frame.

617 for stream decoder, but final=True for the decode function.
618
Georg Brandl07fec3a2006-08-01 18:49:24 +0000619- os.urandom no longer masks unrelated exceptions like SystemExit or
620 KeyboardInterrupt.
621
Tim Peters4643c2f2006-08-10 22:45:34 +0000622- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000623 shutil.copytree on Windows
624
Georg Brandle34ac7c2006-07-30 11:07:23 +0000625- Bug #1002398: The documentation for os.path.sameopenfile now correctly
626 refers to file descriptors, not file objects.
627
Tim Peterscbdd3502006-09-05 01:47:53 +0000628- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000629 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000630 #1513611, and probably others.
631
Georg Brandledd9b0d2006-07-29 09:33:26 +0000632- Bug #1441397: The compiler module now recognizes module and function
633 docstrings correctly as it did in Python 2.4.
634
Tim Peters6f681472006-07-27 23:44:37 +0000635- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
636 lost that tests are sorted by name before being run. This rarely
637 matters for well-written tests, but can create baffling symptoms if
638 side effects from one test to the next affect outcomes. ``DocTestFinder``
639 has been changed to sort the list of tests it returns.
640
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000641- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000642 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000643
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000644- Bug #978833: Really close underlying socket in _socketobject.close.
645
Georg Brandldb232dc2006-08-20 13:15:43 +0000646- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
647 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000648
Georg Brandlcf0c1722006-07-26 07:23:32 +0000649- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
650 to recursive calls and call it with the failing package name.
651
Martin v. Löwis0b483032006-07-25 09:53:12 +0000652- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
653
Georg Brandlc13c34c2006-07-24 14:09:56 +0000654- Patch #1515343: Fix printing of deprecated string exceptions with a
655 value in the traceback module.
656
Greg Ward48fae7a2006-07-23 16:05:51 +0000657- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
658
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000659- Patch #1524429: Use repr() instead of backticks in Tkinter again.
660
Brett Cannoncaebe222006-07-18 04:41:36 +0000661- Bug #1520914: Change time.strftime() to accept a zero for any position in its
662 argument tuple. For arguments where zero is illegal, the value is forced to
663 the minimum value that is correct. This is to support an undocumented but
664 common way people used to fill in inconsequential information in the time
665 tuple pre-2.4.
666
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000667- Patch #1220874: Update the binhex module for Mach-O.
668
Barry Warsawb110bad2006-07-21 14:51:07 +0000669- The email package has improved RFC 2231 support, specifically for
670 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
671 (name*0=<blah>) parameter continuations. This may change the types of
672 values returned from email.message.Message.get_param() and friends.
673 Specifically in some cases where non-encoded continuations were used,
674 get_param() used to return a 3-tuple of (None, None, string) whereas now it
675 will just return the string (since non-encoded continuations don't have
676 charset and language parts).
677
678 Also, whereas % values were decoded in all parameter continuations, they are
679 now only decoded in encoded parameter parts.
680
Ronald Oussoren3075e162006-07-25 20:28:55 +0000681- Bug #1517990: IDLE keybindings on MacOS X now work correctly
682
683- Bug #1517996: IDLE now longer shows the default Tk menu when a
684 path browser, class browser or debugger is the frontmost window on MacOS X
685
Barry Warsaw00decd72006-07-27 23:43:15 +0000686- Patch #1520294: Support for getset and member descriptors in types.py,
687 inspect.py, and pydoc.py. Specifically, this allows for querying the type
688 of an object against these built-in types and more importantly, for getting
689 their docstrings printed in the interactive interpreter's help() function.

693-----------------
694
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000695- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
696 a socket operation on a socket with a timeout, the exception will be
697 caught correctly. Previously, the exception was not caught.
698
Thomas Heller1393d6a2006-07-28 21:43:20 +0000699- Patch #1529514: The _ctypes extension is now compiled on more
700 openbsd target platforms.
701
Tim Peters9cab5932006-07-28 00:30:00 +0000702- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
703 a memory leak, affecting pickles and deep copies.
704
Tim Petersbc24eee2006-07-27 01:14:53 +0000705- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

707
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000708- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
709
Thomas Hellerce049a02006-07-14 17:51:14 +0000710- Patch #1521817: Index range checking on ctypes arrays containing
711 exactly one element enabled again. This allows iterating over these
712 arrays, without the need to check the array size before.
713
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000714- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000715 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000716 /dev/null in certain cases; this is now fixed.
717
Thomas Heller47d7a062006-07-12 08:43:47 +0000718- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
719 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000720
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000721- Because of a misspelled preprocessor symbol, ctypes was always
722 compiled without thread support; this is now fixed.
723
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000724- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
725 methods now allow their database parameter to be None as the
726 sleepycat API allows.
727
Matt Flemingec926502006-07-28 11:27:27 +0000728- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
729 bluetooth API compared with Linux and FreeBSD.
730
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000731Tests
732-----
733
734- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
735 how long the test file should take to play. Now accepts taking 2.93 secs
736 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
737
Georg Brandl4793aa32006-07-28 18:31:39 +0000738- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
739 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
740 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000741

745- Bug #1439538: Drop usage of test -e in configure as it is not portable.
746
Ronald Oussoren26cad082006-08-01 21:00:57 +0000747Mac
748---
749
750- PythonLauncher now works correctly when the path to the script contains
751 characters that are treated specially by the shell (such as quotes).
752
753- Bug #1527397: PythonLauncher now launches scripts with the working directory
754 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000755 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000756 expect.

764Core and builtins
765-----------------
766
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000767- Bug #1441486: The literal representation of -(sys.maxint - 1)
768 again evaluates to a int object, not a long.
769
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000770- Bug #1501934: The scope of global variables that are locally assigned
771 using augmented assignment is now correctly determined.
772
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000773- Bug #927248: Recursive method-wrapper objects can now safely
774 be released.
775
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000776- Bug #1417699: Reject locale-specific decimal point in float()
777 and atof().
778
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000779- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
780 omit a default "error" argument for NULL pointer. This allows
781 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000782
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000783- Bug #1519018: 'as' is now validated properly in import statements.
784
Neal Norwitz28746ab2006-07-09 22:14:42 +0000785- On 64 bit systems, int literals that use less than 64 bits are
786 now ints rather than longs.
787
Neal Norwitzed657552006-07-10 00:04:44 +0000788- Bug #1512814, Fix incorrect lineno's when code at module scope
789 started after line 256.
790
Tim Peters32a83612006-07-10 21:08:24 +0000791- New function ``sys._current_frames()`` returns a dict mapping thread
792 id to topmost thread stack frame. This is for expert use, and is
793 especially useful for debugging application deadlocks. The functionality
794 was previously available in Fazal Majid's ``threadframe`` extension
795 module, but it wasn't possible to do this in a wholly threadsafe way from
796 an extension.

813
Thomas Woutersadd19112006-07-05 11:03:49 +0000814- string.Template() now correctly handles tuple-values. Previously,
815 multi-value tuples would raise an exception and single-value tuples would
816 be treated as the value they contain, instead.

843
Brett Cannon53ab5b72006-06-22 16:49:14 +0000844- Bug #1510580: The 'warnings' module improperly required that a Warning
845 category be either a types.ClassType and a subclass of Warning. The proper
846 check is just that it is a subclass with Warning as the documentation states.
847
Georg Brandlad29e632006-06-21 17:45:17 +0000848- The compiler module now correctly compiles the new try-except-finally
849 statement (bug #1509132).
850
Neal Norwitz60373cd2006-06-22 06:30:50 +0000851- The wsgiref package is now installed properly on Unix.
852
Vinay Sajip28e57612006-07-01 10:45:20 +0000853- A bug was fixed in logging.config.fileConfig() which caused a crash on
854 shutdown when fileConfig() was called multiple times.
855
Gerhard Häring762fbd32006-07-02 17:48:30 +0000856- The sqlite3 module did cut off data from the SQLite database at the first
857 null character before sending it to a custom converter. This has been fixed
858 now.

862
Tim Peters112aad32006-07-19 00:03:19 +0000863- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
864 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
865 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000866
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000867- Assigning None to pointer type fields in ctypes structures possible
868 overwrote the wrong fields, this is fixed now.
869
870- Fixed a segfault in _ctypes when ctypes.wintypes were imported
871 on non-Windows platforms.
872
873- Bug #1518190: The ctypes.c_void_p constructor now accepts any
874 integer or long, without range checking.
875
876- Patch #1517790: It is now possible to use custom objects in the ctypes
877 foreign function argtypes sequence as long as they provide a from_param
878 method, no longer is it required that the object is a ctypes type.
879
880- The '_ctypes' extension module now works when Python is configured
881 with the --without-threads option.
882
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000883- Bug #1513646: os.access on Windows now correctly determines write

898
Tim Peters32a83612006-07-10 21:08:24 +0000899- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000900 Previously, the slight difference could cause compilation errors of the
901 'zlib' module on systems with more than one version of zlib.
902
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000903- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000933
934Core and builtins
935-----------------
936
Georg Brandla56b9152006-06-19 06:35:54 +0000937- Patch #1507676: Error messages returned by invalid abstract object operations
938 (such as iterating over an integer) have been improved and now include the
939 type of the offending object to help with debugging.
940
Brett Cannonea3912b2006-06-13 21:46:41 +0000941- Bug #992017: A classic class that defined a __coerce__() method that returned
942 its arguments swapped would infinitely recurse and segfault the interpreter.
943
Neal Norwitz909eb122006-06-12 02:13:21 +0000944- Fix the socket tests so they can be run concurrently.
945
Neal Norwitzb9845e72006-06-12 02:11:18 +0000946- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000947 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000948
Brett Cannon22565aa2006-06-09 22:31:23 +0000949- Bug #532646: object.__call__() will continue looking for the __call__
950 attribute on objects until one without one is found. This leads to recursion
951 when you take a class and set its __call__ attribute to an instance of the
952 class. Originally fixed for classic classes, but this fix is for new-style.
953 Removes the infinite_rec_3 crasher.
954
Georg Brandl24250812006-06-09 18:45:48 +0000955- The string and unicode methods startswith() and endswith() now accept
956 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
957
Brett Cannonde3b0522006-06-08 17:00:45 +0000958- Buffer objects, at the C level, never used the char buffer
959 implementation even when the char buffer for the wrapped object was
960 explicitly requested (originally returned the read or write buffer).
961 Now a TypeError is raised if the char buffer is not present but is
962 requested.
963
Georg Brandlddbaa662006-06-04 21:56:52 +0000964- Patch #1346214: Statements like "if 0: suite" are now again optimized
965 away like they were in Python 2.4.
966
Georg Brandlb7c8f542006-05-27 12:30:25 +0000967- Builtin exceptions are now full-blown new-style classes instead of
968 instances pretending to be classes, which speeds up exception handling
969 by about 80% in comparison to 2.5a2.
970
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000971- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
972 Unicode 4.1.
973
Georg Brandlf4ef1162006-05-26 18:03:31 +0000974- Patch #921466: sys.path_importer_cache is now used to cache valid and
975 invalid file paths for the built-in import machinery which leads to
976 fewer open calls on startup.
977
Tim Peters696cf432006-05-24 21:10:40 +0000978- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
979 of-2 bases. The largest speedup is for inputs with about 1000 decimal
980 digits. Conversion from non-power-of-2 bases remains quadratic-time in
981 the number of input digits (it was and remains linear-time for bases
982 2, 4, 8, 16 and 32).
983
Tim Petersb713ec22006-05-23 18:45:30 +0000984- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
985 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
986 an integer close to ``sys.maxint``. This was repaired by patch
987 #1335972, which also gives a nice speedup.
988
Richard Jonescebbefc2006-05-23 18:28:17 +0000989- Patch #1337051: reduced size of frame objects.
990
991- PyErr_NewException now accepts a tuple of base classes as its
992 "base" parameter.
993
Richard Jones7c88dcc2006-05-23 10:37:38 +0000994- Patch #876206: function call speedup by retaining allocated frame
995 objects.
996
Georg Brandl7b90e162006-05-18 07:01:27 +0000997- Bug #1462152: file() now checks more thoroughly for invalid mode
998 strings and removes a possible "U" before passing the mode to the
999 C library function.
1000
Neal Norwitz1004a532006-05-15 07:17:23 +00001001- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1002
Neal Norwitz373f0a72006-05-15 07:04:36 +00001003- Bug #1487966: Fix SystemError with conditional expression in assignment
1004
Martin v. Löwis879768d2006-05-11 13:28:43 +00001005- WindowsError now has two error code attributes: errno, which carries
1006 the error values from errno.h, and winerror, which carries the error
1007 values from winerror.h. Previous versions put the winerror.h values
1008 (from GetLastError()) into the errno attribute.
1009
Martin v. Löwis77736712006-05-04 05:51:03 +00001010- Patch #1475845: Raise IndentationError for unexpected indent.
1011
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001012- Patch #1479181: split open() and file() from being aliases for each other.
1013
Tim Peters44bd9862006-06-01 13:49:23 +00001014- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1015 methods were always silently ignored by dictionaries when comparing keys.
1016 They are now passed through (except when using the C API function
1017 ``PyDict_GetItem()``, whose semantics did not change).
1018
1019- Bug #1456209: In some obscure cases it was possible for a class with a
1020 custom ``__eq__()`` method to confuse dict internals when class instances
1021 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1022 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001024Extension Modules
1025-----------------
1026
Trent Mick960a3f82006-06-28 20:30:41 +00001027- Bug #1295808: expat symbols should be namespaced in pyexpat
1028
1029- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1030
Brett Cannon6ee7d012006-06-08 16:23:04 +00001031- Change binascii.hexlify to accept a read-only buffer instead of only a char
1032 buffer and actually follow its documentation.
1033
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001034- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1035
Nick Coghlanc649ec52006-05-29 12:43:05 +00001036- Patch #1478788 (modified version): The functional extension module has
1037 been renamed to _functools and a functools Python wrapper module added.
1038 This provides a home for additional function related utilities that are
1039 not specifically about functional programming. See PEP 309.
1040
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001041- Patch #1493701: performance enhancements for struct module.
1042
Georg Brandl378d5922006-05-17 14:26:50 +00001043- Patch #1490224: time.altzone is now set correctly on Cygwin.
1044
Georg Brandl8d3342b2006-05-16 07:38:27 +00001045- Patch #1435422: zlib's compress and decompress objects now have a
1046 copy() method.
1047
Andrew MacIntyre92913322006-06-13 15:04:24 +00001048- Patch #1454481: thread stack size is now tunable at runtime for thread
1049 enabled builds on Windows and systems with Posix threads support.
1050
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001051- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1052 (up to the system limit of 32K characters).
1053
1054- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1055 As a result, these functions now raise WindowsError instead of OSError.
1056
Tim Peters7a822da2006-05-25 21:50:17 +00001057- ``time.clock()`` on Win64 should use the high-performance Windows
1058 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1059 Windows platforms).
1060
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001061- Calling Tk_Init twice is refused if the first call failed as that
1062 may deadlock.
1063
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001064- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1065 accept it without potentially using an uninitialized pointer.
1066
1067- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1068 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1069 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001070
Gregory P. Smith372b5832006-06-05 18:48:21 +00001071- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001072 [pybsddb project SF patch number 1466734]
1073
Gregory P. Smith372b5832006-06-05 18:48:21 +00001074- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1075 parameter is supplied. [SF pybsddb bug #1477863]
1076
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001077- bsddb: the __len__ method of a DB object has been fixed to return correct
1078 results. It could previously incorrectly return 0 in some cases.
1079 Fixes SF bug 1493322 (pybsddb bug 1184012).
1080
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001081- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1082 aborts the db transaction safely when a modifier callback fails.
1083 Fixes SF python patch/bug #1408584.
1084
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001085- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001086 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001087 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1088 database calls that would previously deadlock. [SF python bug #775414]
1089
Vinay Sajip28e57612006-07-01 10:45:20 +00001090- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001091
Walter Dörwald4994d952006-06-19 08:07:50 +00001092- Patch #1506645: add Python wrappers for the curses functions
1093 is_term_resized, resize_term and resizeterm.

1096-------
1097
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001098- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1099 functions.
1100
Martin v. Löwis3798da02006-06-17 18:44:27 +00001101- Patch #812986: Update turtle output even if not tracing.
1102
Vinay Sajip28e57612006-07-01 10:45:20 +00001103- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001104 Tkinter.BaseWidget.
1105
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001106- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1107
Martin v. Löwis337487e2006-06-17 09:15:14 +00001108- Patch #763580: Add name and value arguments to Tkinter variable
1109 classes.
1110
Georg Brandl83cc0d02006-06-14 08:50:03 +00001111- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1112 mime.types file for determining MIME types.
1113
Georg Brandl2605ca82006-06-14 06:08:31 +00001114- Bug #1339007: Shelf objects now don't raise an exception in their
1115 __del__ method when initialization failed.
1116
Martin v. Löwisd8251432006-06-14 05:21:04 +00001117- Patch #1455898: The MBCS codec now supports the incremental mode for
1118 double-byte encodings.
1119
Tim Peters43898b42006-06-14 04:09:25 +00001120- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1121 guarantee that adjacent triples in the return list always describe
1122 non-adjacent blocks. Previously, a pair of matching blocks could end
1123 up being described by multiple adjacent triples that formed a partition
1124 of the matching pair.
1125
Greg Ward0e0c9f42006-06-11 16:24:11 +00001126- Bug #1498146: fix optparse to handle Unicode strings in option help,
1127 description, and epilog.
1128
Greg Wardd1c797e2006-06-11 14:42:41 +00001129- Bug #1366250: minor optparse documentation error.
1130
Greg Ward7f547402006-06-11 00:40:49 +00001131- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1132 clarify docs.
1133
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001134- The wsgiref package has been added to the standard library.
1135
Nick Coghlan676725d2006-06-08 13:54:49 +00001136- The functions update_wrapper() and wraps() have been added to the functools
1137 module. These make it easier to copy relevant metadata from the original
1138 function when writing wrapper functions.
1139
Tim Petersd6a9eef2006-06-05 01:48:21 +00001140- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1141 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001142
Martin v. Löwis3f767792006-06-04 19:36:28 +00001143- Patch #1359618: Speed up charmap encoder by using a trie structure
1144 for lookup.
1145
Tim Petersd609b1a2006-06-02 23:22:51 +00001146- The functions in the ``pprint`` module now sort dictionaries by key
1147 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1148 if and only if its display required more than one line, although that
1149 wasn't documented. The new behavior increases predictability; e.g.,
1150 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1151
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001152- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1153 (thanks for J. J. Lee).
1154
Georg Brandl2b330372006-05-28 20:23:12 +00001155- Patch #1496206: improve urllib2 handling of passwords with respect to
1156 default HTTP and HTTPS ports.
1157
George Yoshidaf3c65de2006-05-28 16:39:09 +00001158- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1159
Bob Ippolito7298f272006-05-23 18:43:47 +00001160- Patch #1281707: speed up gzip.readline.
1161
Georg Brandlb89316f2006-05-17 15:51:16 +00001162- Patch #1180296: Two new functions were added to the locale module:
1163 format_string() to get the effect of "format % items" but locale-aware,
1164 and currency() to format a monetary number with currency sign.
1165
Georg Brandle3a25832006-05-17 14:56:04 +00001166- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1167 and several features added, such as speed and geometry control.
1168
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001169- Patch #1488881: add support for external file objects in bz2 compressed
1170 tarfiles.
1171
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001172- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1173 stdout arguments, making it possible to redirect input and output
1174 for remote debugging.
1175
1176- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1177 a couple of issues, notably handling of long file names using the
1178 GNU LONGNAME extension.
1179
1180- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1181 new flag when ``name`` is already the name of an option flag.
1182
1183- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1184 package.
1185
1186- Patch #1472854: make the rlcompleter.Completer class usable on non-
1187 UNIX platforms.
1188
1189- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1190
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001191- Bug #1472827: correctly escape newlines and tabs in attribute values in
1192 the saxutils.XMLGenerator class.

1227Core and builtins
1228-----------------
1229
Thomas Heller1b046642006-04-18 18:51:06 +00001230- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1231 by converting these apis from macros into exported functions again:
1232
1233 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1234 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1235 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1236 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1237 PyRun_String Py_CompileString
1238
Martin v. Löwis45294a92006-04-18 06:24:08 +00001239- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1240
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001241- All uses of PyStructSequence_InitType have been changed to initialize
1242 the type objects only once, even if the interpreter is initialized
1243 multiple times.
1244
Neal Norwitz61546162006-04-14 05:20:28 +00001245- Bug #1454485, array.array('u') could crash the interpreter. This was
1246 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1247 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1248
1249- Py_UNICODE is unsigned. It was always documented as unsigned, but
1250 due to a bug had a signed value in previous versions.
1251
Tim Peters3a5e8b12006-04-11 01:44:07 +00001252- Patch #837242: ``id()`` of any Python object always gives a positive
1253 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1254 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001255 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001256 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001257
Tim Peters3a5e8b12006-04-11 01:44:07 +00001258 def __hash__(self):
1259 return id(self) # WRONG
1260
1261 because a hash result must be a (short) Python int but it was always
1262 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001263 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001264 was always usable as a hash value before this patch. That's no longer
1265 necessarily so.
1266
1267- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001268 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001269 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001270 #1454844)
1271
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001272- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1273 involving generators that have paused outside of any ``try`` or ``with``
1274 blocks. (In 2.5a1, a paused generator that was part of a reference
1275 cycle could not be garbage collected, regardless of whether it was
1276 paused in a ``try`` or ``with`` block.)

1279-----------------
1280
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001281- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1282 is a macro.
1283
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001284- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1285 fails with an error condition.
1286
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001287- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1288
1289- Bug #1117761: bsddb.*open() no longer raises an exception when using
1290 the cachesize parameter.
1291
1292- Bug #1149413: bsddb.*open() no longer raises an exception when using
1293 a temporary db (file=None) with the 'n' flag to truncate on open.
1294
1295- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1296 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001297
Armin Rigoa9017c32006-04-19 11:50:27 +00001298- Patch #1062014: AF_UNIX sockets under Linux have a special
1299 abstract namespace that is now fully supported.
1300
Anthony Baxter51bcb682006-04-05 14:51:42 +00001301Library
1302-------
1303
Peter Astrand7d1d4362006-07-14 14:04:45 +00001304- Bug #1223937: subprocess.CalledProcessError reports the exit status
1305 of the process using the returncode attribute, instead of
1306 abusing errno.
1307
Tim Peters711bf302006-04-25 03:31:36 +00001308- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1309 a doctest to be skipped (the code is not run, and the expected output
1310 or exception is ignored).
1311
Nick Coghlanda2268f2006-04-24 04:37:15 +00001312- Fixed contextlib.nested to cope with exceptions being raised and
1313 caught inside exit handlers.
1314
Greg Wardab05edc2006-04-23 03:47:58 +00001315- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1316 hex, octal, or binary; add ``append_const`` action; keep going if
1317 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1318 added ``epilog`` for better help generation).
1319
Tim Peters21fbd572006-04-21 21:18:10 +00001320- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1321 called from a thread spawned as a side effect of importing a module.
1322
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001323- The pydoc module now supports documenting packages contained in
1324 .zip or .egg files.
1325
1326- The pkgutil module now has several new utility functions, such
1327 as ``walk_packages()`` to support working with packages that are either
1328 in the filesystem or zip files.
1329
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001330- The mailbox module can now modify and delete messages from
1331 mailboxes, in addition to simply reading them. Thanks to Gregory
1332 K. Johnson for writing the code, and to the 2005 Google Summer of
1333 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001334
Tim Petersc7605f22006-04-17 21:12:33 +00001335- The ``__del__`` method of class ``local`` in module ``_threading_local``
1336 returned before accomplishing any of its intended cleanup.
1337
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001338- Patch #790710: Add breakpoint command lists in pdb.
1339
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001340- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001342- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1343
Anthony Baxtere29002c2006-04-12 12:07:31 +00001344- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1345 Windows. Bug #1469163.
1346
Phillip J. Eby47032112006-04-11 01:07:43 +00001347- The warnings, linecache, inspect, traceback, site, and doctest modules
1348 were updated to work correctly with modules imported from zipfiles or
1349 via other PEP 302 __loader__ objects.
1350
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001351- Patch #1467770: Reduce usage of subprocess._active to processes which
1352 the application hasn't waited on.
1353
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001354- Patch #1462222: Fix Tix.Grid.
1355
Neal Norwitza31bf182006-04-09 03:35:43 +00001356- Fix exception when doing glob.glob('anything*/')
1357
Skip Montanaro262fb922006-04-21 02:31:07 +00001358- The pstats.Stats class accepts an optional stream keyword argument to
1359 direct output to an alternate file-like object.
1360
Anthony Baxter51bcb682006-04-05 14:51:42 +00001361Build
1362-----
1363
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001364- The Makefile now has a reindent target, which runs reindent.py on
1365 the library.
1366
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001367- Patch #1470875: Building Python with MS Free Compiler
1368
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001369- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001370
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001371- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1372 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001373 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001374 CXX from --with-cxx-main, see description in README.
1375
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001376- Patch #1429775: Link extension modules with the shared libpython.
1377
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001378- Fixed a libffi build problem on MIPS systems.
1379
Tim Peters8931ff12006-05-13 23:28:20 +00001380- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1381 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1382 and "%zu" for unsigned integers of type ``size_t``.
1383
Anthony Baxter51bcb682006-04-05 14:51:42 +00001384Tests
1385-----
1386
Nick Coghlanda2268f2006-04-24 04:37:15 +00001387- test_contextlib now checks contextlib.nested can cope with exceptions
1388 being raised and caught inside exit handlers.
1389
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001390- test_cmd_line now checks operation of the -m and -c command switches
1391
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001392- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1393 it separately and by hand. It also wasn't cleaning up its changes to
1394 the current Decimal context.
1395
Thomas Woutersabd08882006-04-26 15:53:30 +00001396- regrtest.py now has a -M option to run tests that test the new limits of
1397 containers, on 64-bit architectures. Running these tests is only sensible
1398 on 64-bit machines with more than two gigabytes of memory. The argument
1399 passed is the maximum amount of memory for the tests to use.
1400
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001401Tools
1402-----
1403
1404- Added the Python benchmark suite pybench to the Tools/ directory;
1405 contributed by Marc-Andre Lemburg.

1408-------------
1409
Tim Petersb06d28c2006-05-12 01:57:59 +00001410- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1411
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001412- PEP 343: Added Context Types section to the library reference
1413 and attempted to bring other PEP 343 related documentation into
1414 line with the implementation and/or python-dev discussions.
1415
Tim Peters8dc73d22006-04-24 02:03:16 +00001416- Bug #1337990: clarified that ``doctest`` does not support examples
1417 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001420What's New in Python 2.5 alpha 1?
1421=================================
1422
Anthony Baxterebed3f62006-04-03 15:03:44 +00001423*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001424
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001425Core and builtins
1426-----------------
1427
Nick Coghlan43832302006-04-23 17:04:07 +00001428- PEP 338: -m command line switch now delegates to runpy.run_module
1429 allowing it to support modules in packages and zipfiles
1430
Martin v. Löwisc661b882006-04-20 04:54:23 +00001431- On Windows, .DLL is not an accepted file name extension for
1432 extension modules anymore; extensions are only found if they
1433 end in .PYD.
1434
Martin v. Löwisea62d252006-04-03 10:56:49 +00001435- Bug #1421664: sys.stderr.encoding is now set to the same value as
1436 sys.stdout.encoding.
1437
Neal Norwitz92e212f2006-04-03 04:48:37 +00001438- __import__ accepts keyword arguments.
1439
Georg Brandlccadf842006-03-31 18:54:53 +00001440- Patch #1460496: round() now accepts keyword arguments.
1441
Anthony Baxter262c00a2006-03-30 10:53:17 +00001442- Fixed bug #1459029 - unicode reprs were double-escaped.
1443
Hye-Shik Changd478f342006-03-23 12:32:36 +00001444- Patch #1396919: The system scope threads are reenabled on FreeBSD
1445 5.4 and later versions.
1446
Neal Norwitze98ccf62006-03-23 05:39:47 +00001447- Bug #1115379: Compiling a Unicode string with an encoding declaration
1448 now gives a SyntaxError.
1449
Georg Brandlabd1ff82006-03-18 07:59:59 +00001450- Previously, Python code had no easy way to access the contents of a
1451 cell object. Now, a ``cell_contents`` attribute has been added
1452 (closes patch #1170323).
1453
Tim Peterscf79aac2006-03-16 01:14:46 +00001454- Patch #1123430: Python's small-object allocator now returns an arena to
1455 the system ``free()`` when all memory within an arena becomes unused
1456 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1457 freed. Some applications will see a drop in virtual memory size now,
1458 especially long-running applications that, from time to time, temporarily
1459 use a large number of small objects. Note that when Python returns an
1460 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001461 platform C library will in turn return that memory to the operating system.
1462 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001463 appears to be effective at least on Microsoft C and gcc-based systems.
1464 Thanks to Evan Jones for hard work and patience.
1465
Georg Brandl533ff6f2006-03-08 18:09:27 +00001466- Patch #1434038: property() now uses the getter's docstring if there is
1467 no "doc" argument given. This makes it possible to legitimately use
1468 property() as a decorator to produce a read-only property.
1469
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001470- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1471 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1472 of requiring an int or long in slicing and a few other contexts, enabling
1473 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1474
Neal Norwitz995acdf2006-03-07 05:01:00 +00001475- Fixed various bugs reported by Coverity's Prevent tool.
1476
Brett Cannonbf364092006-03-01 04:25:17 +00001477- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1478 new exception base class, BaseException, which has a new message attribute.
1479 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1480 Raising a string exception now raises a DeprecationWarning.
1481
Thomas Woutersfb609f42006-02-28 16:37:25 +00001482- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1483 explicitly relative, using 'from .module import name' to mean 'from the same
1484 package as this module is in. Imports without dots still default to the
1485 old relative-then-absolute, unless 'from __future__ import
1486 absolute_import' is used.
1487
Brett Cannona7446e32006-02-27 23:39:10 +00001488- Properly check if 'warnings' raises an exception (usually when a filter set
1489 to "error" is triggered) when raising a warning for raising string
1490 exceptions.
1491
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001492- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001493 The name was removed from Include/code.h.
1494
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001495- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001496
Guido van Rossum1968ad32006-02-25 22:38:04 +00001497- Patch 1433928:
1498 - The copy module now "copies" function objects (as atomic objects).
1499 - dict.__getitem__ now looks for a __missing__ hook before raising
1500 KeyError.
1501
Tim Peters84ef21c2006-02-28 20:39:06 +00001502- PEP 343: with statement implemented. Needs ``from __future__ import
1503 with_statement``. Use of 'with' as a variable will generate a warning.
1504 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001505 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001506 The following objects have __context__ methods:
1507 - The built-in file type.
1508 - The thread.LockType type.
1509 - The following types defined by the threading module:
1510 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1511 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001512
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001513- Fix the encodings package codec search function to only search
1514 inside its own package. Fixes problem reported in patch #1433198.
1515
1516 Note: Codec packages should implement and register their own
1517 codec search function. PEP 100 has the details.
1518
Tim Peters9ea89d22006-06-04 03:26:02 +00001519- PEP 353: Using ``Py_ssize_t`` as the index type.
1520
1521- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1522 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1523 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1524 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1525 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001526
Neal Norwitzfc76d632006-01-10 06:03:13 +00001527- Patch #1400181, fix unicode string formatting to not use the locale.
1528 This is how string objects work. u'%f' could use , instead of .
1529 for the decimal point. Now both strings and unicode always use periods.
1530
Neal Norwitz671b9e32006-01-09 07:07:12 +00001531- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1532 configure would break checking curses.h.
1533
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001534- Bug #959576: The pwd module is now builtin. This allows Python to be
1535 built on UNIX platforms without $HOME set.
1536
Neal Norwitzc10978f2005-12-19 06:07:16 +00001537- Bug #1072182, fix some potential problems if characters are signed.
1538
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001539- Bug #889500, fix line number on SyntaxWarning for global declarations.
1540
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001541- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1542
Neal Norwitze7214a12005-12-18 05:03:17 +00001543- Support for converting hex strings to floats no longer works.
1544 This was not portable. float('0x3') now raises a ValueError.
1545
Barry Warsaw2a38a862005-12-18 01:27:35 +00001546- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001547 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001548 is now displayed in interactive prompt banner.
1549
Georg Brandlfa166682005-12-17 21:45:17 +00001550- Implementation of PEP 341 - Unification of try/except and try/finally.
1551 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001552 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001553
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001554- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1555 now encodes backslash correctly.
1556
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001557- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1558
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001559- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001560 and long longs.
1561
Neal Norwitz67715f02005-11-09 06:59:35 +00001562- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001563 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001564 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001565
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001566- Replaced most Unicode charmap codecs with new ones using the
1567 new Unicode translate string feature in the builtin charmap
1568 codec; the codecs were created from the mapping tables available
1569 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1570 encodings now include a mapping for the Apple logo)
1571
Tim Peterse3547fd2005-12-16 23:13:57 +00001572- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001573
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001574- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001575
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001576- A new AST parser implementation was completed. The abstract
1577 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001578 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001579
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001580- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001581 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1582
Neal Norwitz708e51a2005-10-03 04:48:15 +00001583- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1584
Neal Norwitz11bd1192005-10-03 00:54:56 +00001585- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1586 Provide a warning when a directory is passed on the command line.
1587
Neal Norwitz40d37812005-10-02 01:48:49 +00001588- Fix segfault with invalid coding.
1589
1590- SF bug #772896: unknown encoding results in MemoryError.
1591
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001592- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001593 supported a __len__() method which evaluated to False when the iterator
1594 was empty.
1595
Guido van Rossum630db602005-09-20 18:49:54 +00001596- On 64-bit platforms, when __len__() returns a value that cannot be
1597 represented as a C int, raise OverflowError.
1598
Skip Montanarof8948ca2005-09-19 03:54:46 +00001599- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001600 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001601
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001602- SF bug #893549: parsing keyword arguments was broken with a few format
1603 codes.
1604
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001605- Changes donated by Elemental Security to make it work on AIX 5.3
1606 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1607 bug #105470: test_pwd fails on 64bit system (Opteron).
1608
Guido van Rossum539c6622005-09-14 17:49:54 +00001609- Changes donated by Elemental Security to make it work on HP-UX 11 on
1610 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1611
Georg Brandl4550b8d2005-08-26 06:43:52 +00001612- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001613 (fixes bug #1119418).
1614
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001615- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1616
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001617- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1618 exceptions that cause a function to exit.
1619
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001620- The implementation of set() and frozenset() was revised to use its
1621 own internal data structure. Memory consumption is reduced by 1/3
1622 and there are modest speed-ups as well. The API is unchanged.
1623
Tim Petersde7990b2005-07-17 23:45:23 +00001624- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1625
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001626- SF bug #1229429: PyObject_CallMethod failed to decrement some
1627 reference counts in some error exit cases.
1628
Tim Petersecc6e6a2005-07-10 22:30:55 +00001629- SF bug #1185883: Python's small-object memory allocator took over
1630 a block managed by the platform C library whenever a realloc specified
1631 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001632 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001633 portable way to copy data from the C-managed block into Python's
1634 small-object space without risking a memory fault. Python's small-object
1635 realloc now leaves such blocks under the control of the platform C
1636 realloc.
1637
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001638- SF bug #1232517: An overflow error was not detected properly when
1639 attempting to convert a large float to an int in os.utime().
1640
Raymond Hettinger3296e692005-06-29 23:29:56 +00001641- SF bug #1224347: hex longs now print with lowercase letters just
1642 like their int counterparts.
1643
Michael W. Hudson188d4362005-06-20 16:52:57 +00001644- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1645 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1646 interpreter states; back out that fix and do a better job (see
1647 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1648 for a longer write-up of the problem).
1649
Michael W. Hudsondf888462005-06-03 14:41:55 +00001650- SF patch #1180995: marshal now uses a binary format by default when
1651 serializing floats.
1652
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001653- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1654 the routines that promise to produce IEEE 754 binary representations
1655 of floats now simply copy bytes around.
1656
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001657- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1658 278.
1659
Brett Cannonc3647ac2005-04-26 03:45:26 +00001660- patch #1109424: int, long, float, complex, and unicode now check for the
1661 proper magic slot for type conversions when subclassed. Previously the
1662 magic slot was ignored during conversion. Semantics now match the way
1663 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001664 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001665 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001666 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001667
Barry Warsawc8d907c2005-04-19 23:43:40 +00001668- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1669 NULL, now raise an AttributeError when attempting to set or delete the
1670 attribute. Previously a TypeError was raised, but this was inconsistent
1671 with the equivalent pure-Python implementation.
1672
Michael W. Hudson774479c2005-04-18 08:46:17 +00001673- It is now safe to call PyGILState_Release() before
1674 PyEval_InitThreads() (note that if there is reason to believe there
1675 are multiple threads around you still must call PyEval_InitThreads()
1676 before using the Python API; this fix is for extension modules that
1677 have no way of knowing if Python is multi-threaded yet).
1678
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001679- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1680 disabled caused a crash.
1681
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001682- Bug #1165306: instancemethod_new allowed the creation of a method
1683 with im_class == im_self == NULL, which caused a crash when called.
1684
Tim Petersecc6e6a2005-07-10 22:30:55 +00001685- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001686 fixes the crash seen in bug #1165761
1687
Raymond Hettinger96229b12005-03-11 06:49:40 +00001688- Added two new builtins, any() and all().
1689
Brett Cannon409d8f22005-03-05 06:47:57 +00001690- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001691 (e.g., ``class C(): pass`` is no longer a syntax error).
1692 Patch #1176012 added support to the 'parser' module and 'compiler' package
1693 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001694
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001695- Patch #1115086: Support PY_LONGLONG in structmember.
1696
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001697- Bug #1155938: new style classes did not check that __init__() was
1698 returning None.
1699
Tim Petersecc6e6a2005-07-10 22:30:55 +00001700- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001701 ('\') with a specific error message.
1702
Martin v. Löwisff232d72005-03-03 09:24:38 +00001703- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1704
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001705- Bug #1124295: the __name__ attribute of file objects was
1706 inadvertently made inaccessible in restricted mode.
1707
Tim Petersecc6e6a2005-07-10 22:30:55 +00001708- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001709 an ferror() call.
1710
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001711- min() and max() now support key= arguments with the same meaning as in
1712 list.sort().
1713
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001714- The peephole optimizer now performs simple constant folding in expressions:
1715 (2+3) --> (5).
1716
Raymond Hettingera422c342005-01-11 03:03:27 +00001717- set and frozenset objects can now be marshalled. SF #1098985.
1718
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001719- Bug #1077106: Poor argument checking could cause memory corruption
1720 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001721
Jeremy Hyltonab630502005-02-04 18:44:06 +00001722- The parser did not complain about future statements in illegal
1723 positions. It once again reports a syntax error if a future
1724 statement occurs after anything other than a doc string.
1725
Neil Schemenauercf52c072005-08-12 17:34:58 +00001726- Change the %s format specifier for str objects so that it returns a
1727 unicode instance if the argument is not an instance of basestring and
1728 calling __str__ on the argument returns a unicode instance.
1729
Tim Petersf4e69282006-02-27 17:15:31 +00001730- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1731 current thread state when the auto-GIL-state machinery knows about
1732 it (since the thread state is being deleted, continuing to remember it
1733 can't help, but can hurt if another thread happens to get created with
1734 the same thread id).
1735
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001736Extension Modules
1737-----------------
1738
Georg Brandl43f08a82006-03-31 18:01:16 +00001739- Patch #1380952: fix SSL objects timing out on consecutive read()s
1740
Neal Norwitz05a45592006-03-20 06:30:08 +00001741- Patch #1309579: wait3 and wait4 were added to the posix module.
1742
Anthony Baxterfa869072006-03-20 05:21:58 +00001743- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1744 In addition, the existing ulaw code was updated.
1745
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001746- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001747 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001748
Neal Norwitz10be10c2006-03-16 06:50:13 +00001749- Everything under lib-old was removed. This includes the following modules:
1750 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001751 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001752 util, whatsound, whrandom, zmod
1753
1754- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1755
1756- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001757 is deprecated. The undocumented re.engine variable no longer exists.
1758
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001759- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1760 SS2 (single-shift 2) escape sequences correctly.
1761
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001762- The unicodedata module was updated to the 4.1 version of the Unicode
1763 database. The 3.2 version is still available as unicodedata.db_3_2_0
1764 for applications that require this specific version (such as IDNA).
1765
Neal Norwitzb62c4332006-03-04 18:35:47 +00001766- The timing module is no longer built by default. It was deprecated
1767 in PEP 4 in Python 2.0 or earlier.
1768
Guido van Rossum1968ad32006-02-25 22:38:04 +00001769- Patch 1433928: Added a new type, defaultdict, to the collections module.
1770 This uses the new __missing__ hook behavior added to dict (see above).
1771
Georg Brandldbd83392006-02-20 09:42:33 +00001772- Bug #854823: socketmodule now builds on Sun platforms even when
1773 INET_ADDRSTRLEN is not defined.
1774
Georg Brandlf4f44152006-02-18 22:29:33 +00001775- Patch #1393157: os.startfile() now has an optional argument to specify
1776 a "command verb" to invoke on the file.
1777
Neal Norwitz082b2df2006-02-07 07:04:46 +00001778- Bug #876637, prevent stack corruption when socket descriptor

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001926- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1927 been renamed to have only a single underscore prefix. This was done to
1928 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001929
Nick Coghlan43832302006-04-23 17:04:07 +00001930- PEP 338: new module runpy defines a run_module function to support
1931 executing modules which provide access to source code or a code object
1932 via the PEP 302 import mechanisms.
1933

1942 in attribute values.
1943
Anthony Baxterc51ee692006-04-01 00:57:31 +00001944- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001945 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001946 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001947 module will not be built.
1948
Tim Petersc17976e2006-04-01 00:26:53 +00001949- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1950 aren't officially supported here, and trying to use them will probably
1951 raise an exception some day. But dicts have been allowed, and "mostly
1952 worked", so support for them won't go away without warning.
1953
Georg Brandl338ef7d2006-03-31 18:42:16 +00001954- Bug #1445068: getpass.getpass() can now be given an explicit stream

1972
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001973- email 4.0 package now integrated. This is largely the same as the email 3.0
1974 package that was included in Python 2.3, except that PEP 8 module names are
1975 now used (e.g. mail.message instead of email.Message). The MIME classes
1976 have been moved to a subpackage (e.g. email.mime.text instead of
1977 email.MIMEText). The old names are still supported for now. Several
1978 deprecated Message methods have been removed and lots of bugs have been
1979 fixed. More details can be found in the email package documentation.
1980
Walter Dörwald40108c92006-03-27 08:15:44 +00001981- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1982 (a subclass of tuple) that provides incremental decoders and encoders
1983 (a way to use stateful codecs without the stream API). Python functions
1984 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1985 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1986 have been added.

1989 a ValueError instead of a StopIteration now (like file and cString.String do).

2059
Neal Norwitz338e7862005-12-23 21:27:46 +00002060- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2061 LoadError as documented, instead of IOError. For compatibility,
2062 LoadError subclasses IOError.
2063
Brett Cannon3cbd0382005-12-16 22:49:23 +00002064- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002065 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2066 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2067 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2068 Ronald L. Rivest offered this advice for Python:
2069
2070 "The consensus of researchers in this area (at least as
2071 expressed at the NIST Hash Function Workshop 10/31/05),
2072 is that SHA-256 is a good choice for the time being, but
2073 that research should continue, and other alternatives may
2074 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002075
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002076- Added a subset of Fredrik Lundh's ElementTree package. Available

2169 Bug #1224621.
2170
Raymond Hettinger68c04532005-06-10 11:05:19 +00002171- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002172 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002173 the generate_tokens() function now accepts a callable argument that
2174 terminates by raising StopIteration.
2175
Georg Brandl9166e1a2005-06-04 09:20:03 +00002176- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2180
Skip Montanaro174dd222005-05-14 20:54:16 +00002181- Patch #1120353: The xmlrpclib module provides better, more transparent,

2184 class at all.
2185
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002186- distutils.commands.upload was added to support uploading distribution

2190 them to PyPI.
2191
Raymond Hettinger267b8682005-03-27 10:47:39 +00002192- decimal operator and comparison methods now return NotImplemented
2193 instead of raising a TypeError when interacting with other types. This
2194 allows other classes to implement __radd__ style methods and have them
2195 work as expected.
2196
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002197- Bug #1163325: Decimal infinities failed to hash. Attempting to
2198 hash a NaN raised an InvalidOperation instead of a TypeError.
2199
Tim Petersecc6e6a2005-07-10 22:30:55 +00002200- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2234
Guido van Rossumd0641422005-02-03 15:01:24 +00002235- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2236 disables recursive traversal through instance attributes, which can
2237 be exploited in various ways.
2238
Tim Peterse3547fd2005-12-16 23:13:57 +00002239- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002240 flags on the HTTP listening socket.
2241
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002242- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2243 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2244
Fred Drakefbdeaad2006-07-29 16:56:15 +00002245- Patches #893642, #1039083: add allow_none, encoding arguments to
2246 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002247

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002250- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2251
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002252- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2253
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002254- Enhancements to the csv module:
2255
2256 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002257 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002258 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002259 + Dialect parameter parsing has been re-implemented to improve error
2260 reporting.
2261 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2262 dictates.
2263 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002264 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002265 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002266 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2267 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002268 + reader now allows \r characters to be quoted (previously it only allowed
2269 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002270 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002271 + Dialect classes passed to the module are no longer instantiated by
2272 the module before being parsed (the former validation scheme required
2273 this, but the mechanism was unreliable).
2274 + The dialect registry now contains instances of the internal
2275 C-coded dialect type, rather than references to python objects.
2276 + the internal c-coded dialect type is now immutable.
2277 + register_dialect now accepts the same keyword dialect specifications
2278 as the reader and writer, allowing the user to register dialects
2279 without first creating a dialect class.
2280 + a configurable limit to the size of parsed fields has been added -
2281 previously, an unmatched quote character could result in the entire
2282 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002283 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002284 the parser field size limit (returning the former limit). The initial
2285 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002286 + A line_num attribute has been added to the reader object, which tracks
2287 the number of lines read from the source iterator. This is not
2288 the same as the number of records returned, as records can span
2289 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002290 + reader and writer objects were not being registered with the cyclic-GC.
2291 This has been fixed.
2292
Brett Cannone6539c42005-01-08 02:43:53 +00002293- _DummyThread objects in the threading module now delete self.__block that is
2294 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2295 lock primitives tend to be limited in number and thus should not be wasted on
2296 a _DummyThread object. Fixes bug #1089632.
2297
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002298- The imghdr module now detects Exif files.
2299
Raymond Hettinger6065d322004-12-20 23:51:53 +00002300- StringIO.truncate() now correctly adjusts the size attribute.
2301 (Bug #951915).
2302
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002303- locale.py now uses an updated locale alias table (built using
2304 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2305 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002306 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002307
Raymond Hettinger3557f422004-12-07 12:02:02 +00002308- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2309
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002310- the pickle module no longer accepts the deprecated None option in the
2311 args tuple returned by __reduce__().
2312
Brett Cannon84667c02004-12-07 03:25:18 +00002313- optparse now optionally imports gettext. This allows its use in setup.py.
2314
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002315- the pickle module no longer uses the deprecated bin parameter.
2316
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002317- the shelve module no longer uses the deprecated binary parameter.
2318
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002319- the pstats module no longer uses the deprecated ignore() method.
2320
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002321- the filecmp module no longer uses the deprecated use_statcache argument.
2322
Raymond Hettinger664347b2004-12-04 21:21:53 +00002323- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2324 extended or overridden by subclasses. Formerly, the subclassed method would
2325 be ignored by the rest of the module. (Bug #1078905).
2326
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002327- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002328 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002329
Walter Dörwald36733692004-12-22 12:50:50 +00002330- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2331 once when a size argument is given. This prevents a buffer overflow in the
2332 tokenizer with very long source lines.
2333
Barry Warsaw538561e2006-01-01 21:48:54 +00002334- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2335 immediately after creating the object, without any intervening
2336 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002337
Skip Montanaro05885812005-01-16 20:48:27 +00002338- The reconvert.quote function can now emit triple-quoted strings. The
2339 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002340
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002341- ``UserString.MutableString`` now supports negative indices in
2342 ``__setitem__`` and ``__delitem__``
2343
Greg Ward40407942005-03-05 02:53:17 +00002344- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2345 correctly.
2346
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002347- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2348 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2349 character even if the user has passed a size parameter to get a proper
2350 line ending. Remove the special handling of a "\r\n" that has been split
2351 between two lines.
2352
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002353- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2354 about illegal code points. The codec now supports PEP 293 style error
2355 handlers.
2356
Walter Dörwald78a78b02005-09-01 12:04:29 +00002357- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002358 from the input stream, so that the output is a byte string in the correct
2359 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002360
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002361- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2362 considering it exactly like a '*'.
2363
Walter Dörwald007f8df2005-10-09 19:42:27 +00002364- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2365 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002366
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002367- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2368
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002369- Patch #1413711: Certain patterns of differences were making difflib
2370 touch the recursion limit.
2371
Walter Dörwald58917a62006-03-31 15:26:22 +00002372- Bug #947906: An object oriented interface has been added to the calendar
2373 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002374 called as a script (e.g. via ``python -mcalendar``). Localized month and
2375 weekday names can be ouput (even if an exotic encoding is used) using
2376 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002377
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002378Build
2379-----
2380
Neal Norwitz602d3392006-03-31 08:21:40 +00002381- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2382 by using -mieee gcc option.
2383
Martin v. Löwis86d66262006-02-17 08:40:11 +00002384- Patch #1432345: Make python compile on DragonFly.
2385
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002386- Build support for Win64-AMD64 was added.
2387
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002388- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2389
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002390- Patch #881820: look for openpty and forkpty also in libbsd.
2391
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002392- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2393 The zlib module is now builtin on Windows.
2394
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002395- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2396
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002397- Bug #1189330: configure did not correctly determine the necessary
2398 value of LINKCC if python was built with GCC 4.0.
2399
Trent Mick8321b422005-07-26 02:29:21 +00002400- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2401 vulnerability in zlib 1.2.1 and 1.2.2.
2402
Brett Cannon08cd5982005-04-24 22:26:38 +00002403- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2404 flags that change binary compatibility. Changes were also made to
2405 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002406 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002407
Bob Ippolitoed233462005-03-29 13:47:59 +00002408- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2409 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2410 no longer exists). This configure patch makes things right.
2411
Martin v. Löwise2713be2005-03-08 15:03:08 +00002412- Bug #1158607: Build with --disable-unicode again.
2413
Brett Cannon46d96232005-02-16 00:07:19 +00002414- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2415 defined. Discovered as a result of not being able to build on OS X.
2416
Brett Cannon516592f2004-12-07 00:42:59 +00002417- setup.py now uses the directories specified in LDFLAGS using the -L option
2418 and in CPPFLAGS using the -I option for adding library and include
2419 directories, respectively, for compiling extension modules against. This has
2420 led to the core being compiled using the values in CPPFLAGS. It also removes
2421 the need for the special-casing of both DarwinPorts and Fink for darwin since
2422 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2423 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2424 Fink, ``-I/opt/local/include`` for DarwinPorts).
2425
Brett Cannon43802422005-02-10 20:48:03 +00002426- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2427 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2428 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2429 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002431C API
2432-----
2433
Tim Petersc9d78aa2006-03-26 23:27:58 +00002434- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2435 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2436 is obtained via the ``PyObject_`` family, it must be released via the
2437 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2438 always been officially true, but when Python's small-object allocator was
2439 introduced, an attempt was made to cater to a few extension modules
2440 discovered at the time that obtained memory via ``PyObject_New`` but
2441 released it via ``PyMem_DEL``. It's years later, and if such code still
2442 exists it will fail now (probably with segfaults, but calling wrong
2443 low-level memory management functions can yield many symptoms).
2444
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002445- Added a C API for set and frozenset objects.
2446
Raymond Hettinger66517482004-12-03 11:45:13 +00002447- Removed PyRange_New().
2448
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002449- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2450 mapping argument now. This string is used as a mapping table. Byte values
2451 greater than the length of the string and 0xFFFE are treated as undefined
2452 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002458- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002459
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002460- Patch #1276356: New resource "urlfetch" is implemented. This enables
2461 even impatient people to run tests that require remote files.
