316
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000317- The return tuple from str.rpartition(sep) is (tail, sep, head) where
318 head is the original string if sep was not found.
319
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000320- Bug #1520864: unpacking singleton tuples in list comprehensions and
321 generator expressions (x for x, in ... ) works again. Fixing this problem
322 required changing the .pyc magic number. This means that .pyc files
323 generated before 2.5c2 will be regenerated.

423Core and builtins
424-----------------
425
Neal Norwitz24b6f202006-09-05 04:43:56 +0000426- Fix infinite recursion when subclassing long and overriding __hash__.
427
428- Fix concatenation (+=) of long strings.
429
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000430- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000431 compared equal or unequal to a string and a UnicodeDecodeError
432 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000433
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000434 Instead, the equal (==) and unequal (!=) comparison operators will
435 now issue a UnicodeWarning and interpret the two objects as
436 unequal. The UnicodeWarning can be filtered as desired using
437 the warning framework, e.g. silenced completely, turned into an
438 exception, logged, etc.
439
440 Note that compare operators other than equal and unequal will still
441 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000442
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000443- Fix segfault when doing string formatting on subclasses of long.
444
445- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
446 with new-style classes.
447
448- Fix bug related to __len__ functions returning negative values with
449 classic classes.
450
451- Patch #1538606, Fix __index__() clipping. There were some problems
452 discovered with the API and how integers that didn't fit into Py_ssize_t
453 were handled. This patch attempts to provide enough alternatives
454 to effectively use __index__.
455
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000456- Bug #1536021: __hash__ may now return long int; the final hash
457 value is obtained by invoking hash on the long int.
458
Thomas Hellerab1049c2006-08-08 17:37:00 +0000459- Bug #1536786: buffer comparison could emit a RuntimeWarning.

462 sys.stdin is closed.
463
Thomas Heller74d36f02006-08-04 18:17:40 +0000464- On Windows, the PyErr_Warn function is now exported from
465 the Python dll again.
466
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000467- Bug #1191458: tracing over for loops now produces a line event
468 on each iteration. Fixing this problem required changing the .pyc
469 magic number. This means that .pyc files generated before 2.5c1
470 will be regenerated.
471
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000472- Bug #1333982: string/number constants were inappropriately stored
473 in the byte code and co_consts even if they were not used, ie
474 immediately popped off the stack.
475
Georg Brandle9462c72006-08-04 18:03:37 +0000476- Fixed a reference-counting problem in property().

479Library
480-------
481
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000482- Fix a bug in the ``compiler`` package that caused invalid code to be
483 generated for generator expressions.
484
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000485- The distutils version has been changed to 2.5.0. The change to
486 keep it programmatically in sync with the Python version running
487 the code (introduced in 2.5b3) has been reverted. It will continue
488 to be maintained manually as static string literal.
489
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000490- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000491 and this cannot be converted to the required C type, an exception is
492 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000493 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000494
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000495- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000496 an exception.
497
Tim Peterscbdd3502006-09-05 01:47:53 +0000498- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000499 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000500 workarounds for clocks with low resolution, to stop the code yielding
501 duplicate UUIDs.
502
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000503- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
504 before raising SystemExit, allowing IDLE to honor quit() and exit().
505
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000506- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
507
Georg Brandl7a1af772006-08-14 21:55:28 +0000508- Patch #1536071: trace.py should now find the full module name of a
509 file correctly even on Windows.

Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000511- logging's atexit hook now runs even if the rest of the module has
512 already been cleaned up.

Guido van Rossum133f4e42006-08-10 17:42:50 +0000515
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000516- Bug #1531405, format_exception no longer raises an exception if
517 str(exception) raised an exception.
518
Neil Schemenauer06ded092006-08-04 16:20:30 +0000519- Fix a bug in the ``compiler`` package that caused invalid code to be

532
Thomas Heller1ce433e2006-08-14 16:20:04 +0000533- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
534 '-no-stack-protector' compiler flag for OpenBSD has been removed.
535
Thomas Heller86720042006-08-14 11:17:48 +0000536- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now

538 function calls. The ctypes version number was changed to 1.0.1.
539
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000540- Bug #1530559, struct.pack raises TypeError where it used to convert.
541 Passing float arguments to struct.pack when integers are expected
542 now triggers a DeprecationWarning.

592Core and builtins
593-----------------
594
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000595- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000596 returned a long (see PEP 353).
597
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000598- Bug #1515471: string.replace() accepts character buffers again.
599
Neal Norwitz07aadb12006-07-30 06:55:48 +0000600- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
601 This provides the proper warning for struct.pack().
602 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
603
Neal Norwitz0d62a062006-07-30 06:53:31 +0000604- Patch #1531113: Fix augmented assignment with yield expressions.
605 Also fix a SystemError when trying to assign to yield expressions.
606
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000607- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
608 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
609 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
610 excessive filesystem operations during imports.
611
Tim Petersbc24eee2006-07-27 01:14:53 +0000612- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
613 operations on signed longs that are formally undefined by C.
614 Unfortunately, at least one compiler now cares about that, so complicated
615 the code to make that compiler happy again.
616
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000617- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Neal Norwitze7563102006-07-17 01:00:16 +0000624- Fix warnings reported by Klocwork's static analysis tool.
625
Neal Norwitz84be93b2006-07-16 01:50:38 +0000626- Bug #1512814, Fix incorrect lineno's when code within a function
627 had more than 255 blank lines.
628
Georg Brandl9dceedb2006-07-12 15:31:17 +0000629- Patch #1521179: Python now accepts the standard options ``--help`` and
630 ``--version`` as well as ``/?`` on Windows.
631
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000632- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000633 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000634 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000635
Tim Peters112aad32006-07-19 00:03:19 +0000636- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000637 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000638 new ``sys._current_frames()`` returns a dictionary with one entry,
639 mapping the faux "thread id" 0 to the current frame.
640
Ronald Oussoren3075e162006-07-25 20:28:55 +0000641- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

645-------
646
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000647- Correction of patch #1455898: In the mbcs decoder, set final=False
648 for stream decoder, but final=True for the decode function.
649
Georg Brandl07fec3a2006-08-01 18:49:24 +0000650- os.urandom no longer masks unrelated exceptions like SystemExit or
651 KeyboardInterrupt.
652
Tim Peters4643c2f2006-08-10 22:45:34 +0000653- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000654 shutil.copytree on Windows
655
Georg Brandle34ac7c2006-07-30 11:07:23 +0000656- Bug #1002398: The documentation for os.path.sameopenfile now correctly
657 refers to file descriptors, not file objects.
658
Tim Peterscbdd3502006-09-05 01:47:53 +0000659- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000660 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000661 #1513611, and probably others.
662
Georg Brandledd9b0d2006-07-29 09:33:26 +0000663- Bug #1441397: The compiler module now recognizes module and function
664 docstrings correctly as it did in Python 2.4.
665
Tim Peters6f681472006-07-27 23:44:37 +0000666- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
667 lost that tests are sorted by name before being run. This rarely
668 matters for well-written tests, but can create baffling symptoms if
669 side effects from one test to the next affect outcomes. ``DocTestFinder``
670 has been changed to sort the list of tests it returns.
671
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000672- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000673 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000674
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000675- Bug #978833: Really close underlying socket in _socketobject.close.

Georg Brandldb232dc2006-08-20 13:15:43 +0000677- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
678 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000679
Georg Brandlcf0c1722006-07-26 07:23:32 +0000680- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
681 to recursive calls and call it with the failing package name.
682
Martin v. Löwis0b483032006-07-25 09:53:12 +0000683- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
684
Georg Brandlc13c34c2006-07-24 14:09:56 +0000685- Patch #1515343: Fix printing of deprecated string exceptions with a
686 value in the traceback module.
687
Greg Ward48fae7a2006-07-23 16:05:51 +0000688- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
689
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000690- Patch #1524429: Use repr() instead of backticks in Tkinter again.
691
Brett Cannoncaebe222006-07-18 04:41:36 +0000692- Bug #1520914: Change time.strftime() to accept a zero for any position in its
693 argument tuple. For arguments where zero is illegal, the value is forced to
694 the minimum value that is correct. This is to support an undocumented but
695 common way people used to fill in inconsequential information in the time
696 tuple pre-2.4.
697
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000698- Patch #1220874: Update the binhex module for Mach-O.
699
Barry Warsawb110bad2006-07-21 14:51:07 +0000700- The email package has improved RFC 2231 support, specifically for
701 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
702 (name*0=<blah>) parameter continuations. This may change the types of
703 values returned from email.message.Message.get_param() and friends.
704 Specifically in some cases where non-encoded continuations were used,
705 get_param() used to return a 3-tuple of (None, None, string) whereas now it
706 will just return the string (since non-encoded continuations don't have
707 charset and language parts).
708
709 Also, whereas % values were decoded in all parameter continuations, they are
710 now only decoded in encoded parameter parts.
711
Ronald Oussoren3075e162006-07-25 20:28:55 +0000712- Bug #1517990: IDLE keybindings on MacOS X now work correctly
713
714- Bug #1517996: IDLE now longer shows the default Tk menu when a
715 path browser, class browser or debugger is the frontmost window on MacOS X
716
Barry Warsaw00decd72006-07-27 23:43:15 +0000717- Patch #1520294: Support for getset and member descriptors in types.py,
718 inspect.py, and pydoc.py. Specifically, this allows for querying the type
719 of an object against these built-in types and more importantly, for getting
720 their docstrings printed in the interactive interpreter's help() function.

725
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000726- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
727 a socket operation on a socket with a timeout, the exception will be
728 caught correctly. Previously, the exception was not caught.
729
Thomas Heller1393d6a2006-07-28 21:43:20 +0000730- Patch #1529514: The _ctypes extension is now compiled on more
731 openbsd target platforms.
732
Tim Peters9cab5932006-07-28 00:30:00 +0000733- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
734 a memory leak, affecting pickles and deep copies.
735
Tim Petersbc24eee2006-07-27 01:14:53 +0000736- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

738
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000739- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
740
Thomas Hellerce049a02006-07-14 17:51:14 +0000741- Patch #1521817: Index range checking on ctypes arrays containing
742 exactly one element enabled again. This allows iterating over these
743 arrays, without the need to check the array size before.
744
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000745- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000746 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000747 /dev/null in certain cases; this is now fixed.
748
Thomas Heller47d7a062006-07-12 08:43:47 +0000749- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
750 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000751
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000752- Because of a misspelled preprocessor symbol, ctypes was always
753 compiled without thread support; this is now fixed.
754
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000755- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
756 methods now allow their database parameter to be None as the
757 sleepycat API allows.
758
Matt Flemingec926502006-07-28 11:27:27 +0000759- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
760 bluetooth API compared with Linux and FreeBSD.
761
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000762Tests
763-----
764
765- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
766 how long the test file should take to play. Now accepts taking 2.93 secs
767 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
768
Georg Brandl4793aa32006-07-28 18:31:39 +0000769- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
770 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
771 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000778Mac
779---
780
781- PythonLauncher now works correctly when the path to the script contains
782 characters that are treated specially by the shell (such as quotes).
783
784- Bug #1527397: PythonLauncher now launches scripts with the working directory
785 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000786 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000787 expect.

796-----------------
797
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000798- Bug #1441486: The literal representation of -(sys.maxint - 1)
799 again evaluates to a int object, not a long.
800
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000801- Bug #1501934: The scope of global variables that are locally assigned
802 using augmented assignment is now correctly determined.
803
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000804- Bug #927248: Recursive method-wrapper objects can now safely
805 be released.
806
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000807- Bug #1417699: Reject locale-specific decimal point in float()
808 and atof().
809
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000810- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
811 omit a default "error" argument for NULL pointer. This allows
812 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000813
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000814- Bug #1519018: 'as' is now validated properly in import statements.
815
Neal Norwitz28746ab2006-07-09 22:14:42 +0000816- On 64 bit systems, int literals that use less than 64 bits are
817 now ints rather than longs.
818
Neal Norwitzed657552006-07-10 00:04:44 +0000819- Bug #1512814, Fix incorrect lineno's when code at module scope
820 started after line 256.
821
Tim Peters32a83612006-07-10 21:08:24 +0000822- New function ``sys._current_frames()`` returns a dict mapping thread
823 id to topmost thread stack frame. This is for expert use, and is
824 especially useful for debugging application deadlocks. The functionality
825 was previously available in Fazal Majid's ``threadframe`` extension
826 module, but it wasn't possible to do this in a wholly threadsafe way from
827 an extension.

Thomas Woutersadd19112006-07-05 11:03:49 +0000845- string.Template() now correctly handles tuple-values. Previously,
846 multi-value tuples would raise an exception and single-value tuples would
847 be treated as the value they contain, instead.
848
Martin v. Löwisede77f52006-07-03 13:01:35 +0000849- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

857
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000858- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000859 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000860
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000861- Bug #1514703: Only setup canvas window in turtle when the canvas
862 is created.
863
Martin v. Löwis7596e832006-07-01 15:33:37 +0000864- Bug #1513223: .close() of a _socketobj now releases the underlying
865 socket again, which then gets closed as it becomes unreferenced.

868 attribute values.
869
870- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
871 sgmllib ('[' and ']' were not accepted).
872
Georg Brandl1be63af2006-06-28 20:23:25 +0000873- Fix a bug in the turtle module's end_fill function.
874
Brett Cannon53ab5b72006-06-22 16:49:14 +0000875- Bug #1510580: The 'warnings' module improperly required that a Warning
876 category be either a types.ClassType and a subclass of Warning. The proper
877 check is just that it is a subclass with Warning as the documentation states.
878
Georg Brandlad29e632006-06-21 17:45:17 +0000879- The compiler module now correctly compiles the new try-except-finally
880 statement (bug #1509132).
881
Neal Norwitz60373cd2006-06-22 06:30:50 +0000882- The wsgiref package is now installed properly on Unix.
883
Vinay Sajip28e57612006-07-01 10:45:20 +0000884- A bug was fixed in logging.config.fileConfig() which caused a crash on
885 shutdown when fileConfig() was called multiple times.
886
Gerhard Häring762fbd32006-07-02 17:48:30 +0000887- The sqlite3 module did cut off data from the SQLite database at the first
888 null character before sending it to a custom converter. This has been fixed
889 now.

Tim Peters112aad32006-07-19 00:03:19 +0000894- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
895 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
896 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000897
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000898- Assigning None to pointer type fields in ctypes structures possible
899 overwrote the wrong fields, this is fixed now.
900
901- Fixed a segfault in _ctypes when ctypes.wintypes were imported
902 on non-Windows platforms.
903
904- Bug #1518190: The ctypes.c_void_p constructor now accepts any
905 integer or long, without range checking.
906
907- Patch #1517790: It is now possible to use custom objects in the ctypes
908 foreign function argtypes sequence as long as they provide a from_param
909 method, no longer is it required that the object is a ctypes type.
910
911- The '_ctypes' extension module now works when Python is configured
912 with the --without-threads option.
913
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000914- Bug #1513646: os.access on Windows now correctly determines write
915 access, again.
916
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000917- Bug #1512695: cPickle.loads could crash if it was interrupted with

929
Tim Peters32a83612006-07-10 21:08:24 +0000930- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000931 Previously, the slight difference could cause compilation errors of the
932 'zlib' module on systems with more than one version of zlib.
933
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000934- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000964
965Core and builtins
966-----------------
967
Georg Brandla56b9152006-06-19 06:35:54 +0000968- Patch #1507676: Error messages returned by invalid abstract object operations
969 (such as iterating over an integer) have been improved and now include the
970 type of the offending object to help with debugging.
971
Brett Cannonea3912b2006-06-13 21:46:41 +0000972- Bug #992017: A classic class that defined a __coerce__() method that returned
973 its arguments swapped would infinitely recurse and segfault the interpreter.
974
Neal Norwitz909eb122006-06-12 02:13:21 +0000975- Fix the socket tests so they can be run concurrently.
976
Neal Norwitzb9845e72006-06-12 02:11:18 +0000977- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000978 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000979
Brett Cannon22565aa2006-06-09 22:31:23 +0000980- Bug #532646: object.__call__() will continue looking for the __call__
981 attribute on objects until one without one is found. This leads to recursion
982 when you take a class and set its __call__ attribute to an instance of the
983 class. Originally fixed for classic classes, but this fix is for new-style.
984 Removes the infinite_rec_3 crasher.
985
Georg Brandl24250812006-06-09 18:45:48 +0000986- The string and unicode methods startswith() and endswith() now accept
987 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
988
Brett Cannonde3b0522006-06-08 17:00:45 +0000989- Buffer objects, at the C level, never used the char buffer
990 implementation even when the char buffer for the wrapped object was
991 explicitly requested (originally returned the read or write buffer).
992 Now a TypeError is raised if the char buffer is not present but is
993 requested.
994
Georg Brandlddbaa662006-06-04 21:56:52 +0000995- Patch #1346214: Statements like "if 0: suite" are now again optimized
996 away like they were in Python 2.4.
997
Georg Brandlb7c8f542006-05-27 12:30:25 +0000998- Builtin exceptions are now full-blown new-style classes instead of
999 instances pretending to be classes, which speeds up exception handling
1000 by about 80% in comparison to 2.5a2.
1001
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001002- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1003 Unicode 4.1.
1004
Georg Brandlf4ef1162006-05-26 18:03:31 +00001005- Patch #921466: sys.path_importer_cache is now used to cache valid and
1006 invalid file paths for the built-in import machinery which leads to
1007 fewer open calls on startup.
1008
Tim Peters696cf432006-05-24 21:10:40 +00001009- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1010 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1011 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1012 the number of input digits (it was and remains linear-time for bases
1013 2, 4, 8, 16 and 32).
1014
Tim Petersb713ec22006-05-23 18:45:30 +00001015- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1016 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1017 an integer close to ``sys.maxint``. This was repaired by patch
1018 #1335972, which also gives a nice speedup.
1019
Richard Jonescebbefc2006-05-23 18:28:17 +00001020- Patch #1337051: reduced size of frame objects.
1021
1022- PyErr_NewException now accepts a tuple of base classes as its
1023 "base" parameter.
1024
Richard Jones7c88dcc2006-05-23 10:37:38 +00001025- Patch #876206: function call speedup by retaining allocated frame
1026 objects.
1027
Georg Brandl7b90e162006-05-18 07:01:27 +00001028- Bug #1462152: file() now checks more thoroughly for invalid mode
1029 strings and removes a possible "U" before passing the mode to the
1030 C library function.
1031
Neal Norwitz1004a532006-05-15 07:17:23 +00001032- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1033
Neal Norwitz373f0a72006-05-15 07:04:36 +00001034- Bug #1487966: Fix SystemError with conditional expression in assignment
1035
Martin v. Löwis879768d2006-05-11 13:28:43 +00001036- WindowsError now has two error code attributes: errno, which carries
1037 the error values from errno.h, and winerror, which carries the error
1038 values from winerror.h. Previous versions put the winerror.h values
1039 (from GetLastError()) into the errno attribute.
1040
Martin v. Löwis77736712006-05-04 05:51:03 +00001041- Patch #1475845: Raise IndentationError for unexpected indent.
1042
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001043- Patch #1479181: split open() and file() from being aliases for each other.
1044
Tim Peters44bd9862006-06-01 13:49:23 +00001045- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1046 methods were always silently ignored by dictionaries when comparing keys.
1047 They are now passed through (except when using the C API function
1048 ``PyDict_GetItem()``, whose semantics did not change).
1049
1050- Bug #1456209: In some obscure cases it was possible for a class with a
1051 custom ``__eq__()`` method to confuse dict internals when class instances
1052 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1053 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001055Extension Modules
1056-----------------
1057
Trent Mick960a3f82006-06-28 20:30:41 +00001058- Bug #1295808: expat symbols should be namespaced in pyexpat
1059
1060- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1061
Brett Cannon6ee7d012006-06-08 16:23:04 +00001062- Change binascii.hexlify to accept a read-only buffer instead of only a char
1063 buffer and actually follow its documentation.
1064
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001065- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1066
Nick Coghlanc649ec52006-05-29 12:43:05 +00001067- Patch #1478788 (modified version): The functional extension module has
1068 been renamed to _functools and a functools Python wrapper module added.
1069 This provides a home for additional function related utilities that are
1070 not specifically about functional programming. See PEP 309.
1071
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001072- Patch #1493701: performance enhancements for struct module.
1073
Georg Brandl378d5922006-05-17 14:26:50 +00001074- Patch #1490224: time.altzone is now set correctly on Cygwin.
1075
Georg Brandl8d3342b2006-05-16 07:38:27 +00001076- Patch #1435422: zlib's compress and decompress objects now have a
1077 copy() method.
1078
Andrew MacIntyre92913322006-06-13 15:04:24 +00001079- Patch #1454481: thread stack size is now tunable at runtime for thread
1080 enabled builds on Windows and systems with Posix threads support.
1081
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001082- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1083 (up to the system limit of 32K characters).
1084
1085- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1086 As a result, these functions now raise WindowsError instead of OSError.
1087
Tim Peters7a822da2006-05-25 21:50:17 +00001088- ``time.clock()`` on Win64 should use the high-performance Windows
1089 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1090 Windows platforms).
1091
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001092- Calling Tk_Init twice is refused if the first call failed as that
1093 may deadlock.
1094
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001095- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1096 accept it without potentially using an uninitialized pointer.
1097
1098- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1099 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1100 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001101
Gregory P. Smith372b5832006-06-05 18:48:21 +00001102- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001103 [pybsddb project SF patch number 1466734]
1104
Gregory P. Smith372b5832006-06-05 18:48:21 +00001105- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1106 parameter is supplied. [SF pybsddb bug #1477863]
1107
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001108- bsddb: the __len__ method of a DB object has been fixed to return correct
1109 results. It could previously incorrectly return 0 in some cases.
1110 Fixes SF bug 1493322 (pybsddb bug 1184012).
1111
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001112- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1113 aborts the db transaction safely when a modifier callback fails.
1114 Fixes SF python patch/bug #1408584.
1115
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001116- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001117 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001118 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1119 database calls that would previously deadlock. [SF python bug #775414]
1120
Vinay Sajip28e57612006-07-01 10:45:20 +00001121- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001122
Walter Dörwald4994d952006-06-19 08:07:50 +00001123- Patch #1506645: add Python wrappers for the curses functions
1124 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001125

1127-------
1128
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001129- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1130 functions.
1131
Martin v. Löwis3798da02006-06-17 18:44:27 +00001132- Patch #812986: Update turtle output even if not tracing.
1133
Vinay Sajip28e57612006-07-01 10:45:20 +00001134- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001135 Tkinter.BaseWidget.
1136
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001137- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1138
Martin v. Löwis337487e2006-06-17 09:15:14 +00001139- Patch #763580: Add name and value arguments to Tkinter variable
1140 classes.
1141
Georg Brandl83cc0d02006-06-14 08:50:03 +00001142- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1143 mime.types file for determining MIME types.
1144
Georg Brandl2605ca82006-06-14 06:08:31 +00001145- Bug #1339007: Shelf objects now don't raise an exception in their
1146 __del__ method when initialization failed.
1147
Martin v. Löwisd8251432006-06-14 05:21:04 +00001148- Patch #1455898: The MBCS codec now supports the incremental mode for
1149 double-byte encodings.
1150
Tim Peters43898b42006-06-14 04:09:25 +00001151- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1152 guarantee that adjacent triples in the return list always describe
1153 non-adjacent blocks. Previously, a pair of matching blocks could end
1154 up being described by multiple adjacent triples that formed a partition
1155 of the matching pair.
1156
Greg Ward0e0c9f42006-06-11 16:24:11 +00001157- Bug #1498146: fix optparse to handle Unicode strings in option help,
1158 description, and epilog.
1159
Greg Wardd1c797e2006-06-11 14:42:41 +00001160- Bug #1366250: minor optparse documentation error.
1161
Greg Ward7f547402006-06-11 00:40:49 +00001162- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1163 clarify docs.
1164
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001165- The wsgiref package has been added to the standard library.
1166
Nick Coghlan676725d2006-06-08 13:54:49 +00001167- The functions update_wrapper() and wraps() have been added to the functools
1168 module. These make it easier to copy relevant metadata from the original
1169 function when writing wrapper functions.
1170
Tim Petersd6a9eef2006-06-05 01:48:21 +00001171- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1172 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001173
Martin v. Löwis3f767792006-06-04 19:36:28 +00001174- Patch #1359618: Speed up charmap encoder by using a trie structure
1175 for lookup.
1176
Tim Petersd609b1a2006-06-02 23:22:51 +00001177- The functions in the ``pprint`` module now sort dictionaries by key
1178 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1179 if and only if its display required more than one line, although that
1180 wasn't documented. The new behavior increases predictability; e.g.,
1181 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1182
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001183- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1184 (thanks for J. J. Lee).
1185
Georg Brandl2b330372006-05-28 20:23:12 +00001186- Patch #1496206: improve urllib2 handling of passwords with respect to
1187 default HTTP and HTTPS ports.
1188
George Yoshidaf3c65de2006-05-28 16:39:09 +00001189- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1190
Bob Ippolito7298f272006-05-23 18:43:47 +00001191- Patch #1281707: speed up gzip.readline.
1192
Georg Brandlb89316f2006-05-17 15:51:16 +00001193- Patch #1180296: Two new functions were added to the locale module:
1194 format_string() to get the effect of "format % items" but locale-aware,
1195 and currency() to format a monetary number with currency sign.
1196
Georg Brandle3a25832006-05-17 14:56:04 +00001197- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1198 and several features added, such as speed and geometry control.
1199
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001200- Patch #1488881: add support for external file objects in bz2 compressed
1201 tarfiles.
1202
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001203- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1204 stdout arguments, making it possible to redirect input and output
1205 for remote debugging.
1206
1207- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1208 a couple of issues, notably handling of long file names using the
1209 GNU LONGNAME extension.
1210
1211- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1212 new flag when ``name`` is already the name of an option flag.
1213

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001253What's New in Python 2.5 alpha 2?
1254=================================
1255
1256*Release date: 27-APR-2006*
1257
1258Core and builtins
1259-----------------
1260
Thomas Heller1b046642006-04-18 18:51:06 +00001261- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1262 by converting these apis from macros into exported functions again:
1263
1264 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1265 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1266 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1267 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1268 PyRun_String Py_CompileString
1269
Martin v. Löwis45294a92006-04-18 06:24:08 +00001270- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1271
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001272- All uses of PyStructSequence_InitType have been changed to initialize
1273 the type objects only once, even if the interpreter is initialized
1274 multiple times.
1275
Neal Norwitz61546162006-04-14 05:20:28 +00001276- Bug #1454485, array.array('u') could crash the interpreter. This was
1277 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1278 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1279
1280- Py_UNICODE is unsigned. It was always documented as unsigned, but
1281 due to a bug had a signed value in previous versions.
1282
Tim Peters3a5e8b12006-04-11 01:44:07 +00001283- Patch #837242: ``id()`` of any Python object always gives a positive
1284 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1285 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001286 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001287 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001288
Tim Peters3a5e8b12006-04-11 01:44:07 +00001289 def __hash__(self):
1290 return id(self) # WRONG
1291
1292 because a hash result must be a (short) Python int but it was always
1293 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001294 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001295 was always usable as a hash value before this patch. That's no longer
1296 necessarily so.
1297
1298- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001299 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001300 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001301 #1454844)
1302
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001303- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1304 involving generators that have paused outside of any ``try`` or ``with``
1305 blocks. (In 2.5a1, a paused generator that was part of a reference
1306 cycle could not be garbage collected, regardless of whether it was
1307 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001308
Anthony Baxter51bcb682006-04-05 14:51:42 +00001309Extension Modules
1310-----------------
1311
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001312- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1313 is a macro.
1314
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001315- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1316 fails with an error condition.
1317
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001318- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1319
1320- Bug #1117761: bsddb.*open() no longer raises an exception when using
1321 the cachesize parameter.
1322
1323- Bug #1149413: bsddb.*open() no longer raises an exception when using
1324 a temporary db (file=None) with the 'n' flag to truncate on open.
1325
1326- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1327 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001328
Armin Rigoa9017c32006-04-19 11:50:27 +00001329- Patch #1062014: AF_UNIX sockets under Linux have a special
1330 abstract namespace that is now fully supported.
1331
Anthony Baxter51bcb682006-04-05 14:51:42 +00001332Library
1333-------
1334
Peter Astrand7d1d4362006-07-14 14:04:45 +00001335- Bug #1223937: subprocess.CalledProcessError reports the exit status
1336 of the process using the returncode attribute, instead of
1337 abusing errno.
1338
Tim Peters711bf302006-04-25 03:31:36 +00001339- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1340 a doctest to be skipped (the code is not run, and the expected output
1341 or exception is ignored).
1342
Nick Coghlanda2268f2006-04-24 04:37:15 +00001343- Fixed contextlib.nested to cope with exceptions being raised and
1344 caught inside exit handlers.
1345
Greg Wardab05edc2006-04-23 03:47:58 +00001346- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1347 hex, octal, or binary; add ``append_const`` action; keep going if
1348 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1349 added ``epilog`` for better help generation).
1350
Tim Peters21fbd572006-04-21 21:18:10 +00001351- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1352 called from a thread spawned as a side effect of importing a module.
1353
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001354- The pydoc module now supports documenting packages contained in
1355 .zip or .egg files.
1356
1357- The pkgutil module now has several new utility functions, such
1358 as ``walk_packages()`` to support working with packages that are either
1359 in the filesystem or zip files.
1360
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001361- The mailbox module can now modify and delete messages from
1362 mailboxes, in addition to simply reading them. Thanks to Gregory
1363 K. Johnson for writing the code, and to the 2005 Google Summer of
1364 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001365
Tim Petersc7605f22006-04-17 21:12:33 +00001366- The ``__del__`` method of class ``local`` in module ``_threading_local``
1367 returned before accomplishing any of its intended cleanup.
1368
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001369- Patch #790710: Add breakpoint command lists in pdb.
1370
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001371- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1372
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001373- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1374
Anthony Baxtere29002c2006-04-12 12:07:31 +00001375- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1376 Windows. Bug #1469163.
1377
Phillip J. Eby47032112006-04-11 01:07:43 +00001378- The warnings, linecache, inspect, traceback, site, and doctest modules
1379 were updated to work correctly with modules imported from zipfiles or
1380 via other PEP 302 __loader__ objects.
1381
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001382- Patch #1467770: Reduce usage of subprocess._active to processes which
1383 the application hasn't waited on.
1384
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001385- Patch #1462222: Fix Tix.Grid.
1386
Neal Norwitza31bf182006-04-09 03:35:43 +00001387- Fix exception when doing glob.glob('anything*/')
1388
Skip Montanaro262fb922006-04-21 02:31:07 +00001389- The pstats.Stats class accepts an optional stream keyword argument to
1390 direct output to an alternate file-like object.
1391
Anthony Baxter51bcb682006-04-05 14:51:42 +00001392Build
1393-----
1394
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001395- The Makefile now has a reindent target, which runs reindent.py on
1396 the library.
1397
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001398- Patch #1470875: Building Python with MS Free Compiler
1399
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001400- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001401
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001402- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1403 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001404 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001405 CXX from --with-cxx-main, see description in README.
1406
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001407- Patch #1429775: Link extension modules with the shared libpython.
1408
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001409- Fixed a libffi build problem on MIPS systems.
1410
Tim Peters8931ff12006-05-13 23:28:20 +00001411- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1412 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1413 and "%zu" for unsigned integers of type ``size_t``.
1414
Anthony Baxter51bcb682006-04-05 14:51:42 +00001415Tests
1416-----
1417
Nick Coghlanda2268f2006-04-24 04:37:15 +00001418- test_contextlib now checks contextlib.nested can cope with exceptions
1419 being raised and caught inside exit handlers.
1420
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001421- test_cmd_line now checks operation of the -m and -c command switches
1422
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001423- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1424 it separately and by hand. It also wasn't cleaning up its changes to
1425 the current Decimal context.
1426
Thomas Woutersabd08882006-04-26 15:53:30 +00001427- regrtest.py now has a -M option to run tests that test the new limits of
1428 containers, on 64-bit architectures. Running these tests is only sensible
1429 on 64-bit machines with more than two gigabytes of memory. The argument
1430 passed is the maximum amount of memory for the tests to use.
1431
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001432Tools
1433-----
1434
1435- Added the Python benchmark suite pybench to the Tools/ directory;
1436 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001437
Anthony Baxter51bcb682006-04-05 14:51:42 +00001438Documentation
1439-------------
1440
Tim Petersb06d28c2006-05-12 01:57:59 +00001441- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1442
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001443- PEP 343: Added Context Types section to the library reference
1444 and attempted to bring other PEP 343 related documentation into
1445 line with the implementation and/or python-dev discussions.
1446
Tim Peters8dc73d22006-04-24 02:03:16 +00001447- Bug #1337990: clarified that ``doctest`` does not support examples
1448 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001451What's New in Python 2.5 alpha 1?
1452=================================
1453
Anthony Baxterebed3f62006-04-03 15:03:44 +00001454*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001455
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001456Core and builtins
1457-----------------
1458
Nick Coghlan43832302006-04-23 17:04:07 +00001459- PEP 338: -m command line switch now delegates to runpy.run_module
1460 allowing it to support modules in packages and zipfiles
1461
Martin v. Löwisc661b882006-04-20 04:54:23 +00001462- On Windows, .DLL is not an accepted file name extension for
1463 extension modules anymore; extensions are only found if they
1464 end in .PYD.
1465
Martin v. Löwisea62d252006-04-03 10:56:49 +00001466- Bug #1421664: sys.stderr.encoding is now set to the same value as
1467 sys.stdout.encoding.
1468
Neal Norwitz92e212f2006-04-03 04:48:37 +00001469- __import__ accepts keyword arguments.
1470
Georg Brandlccadf842006-03-31 18:54:53 +00001471- Patch #1460496: round() now accepts keyword arguments.
1472
Anthony Baxter262c00a2006-03-30 10:53:17 +00001473- Fixed bug #1459029 - unicode reprs were double-escaped.
1474
Hye-Shik Changd478f342006-03-23 12:32:36 +00001475- Patch #1396919: The system scope threads are reenabled on FreeBSD
1476 5.4 and later versions.
1477
Neal Norwitze98ccf62006-03-23 05:39:47 +00001478- Bug #1115379: Compiling a Unicode string with an encoding declaration
1479 now gives a SyntaxError.
1480
Georg Brandlabd1ff82006-03-18 07:59:59 +00001481- Previously, Python code had no easy way to access the contents of a
1482 cell object. Now, a ``cell_contents`` attribute has been added
1483 (closes patch #1170323).
1484
Tim Peterscf79aac2006-03-16 01:14:46 +00001485- Patch #1123430: Python's small-object allocator now returns an arena to
1486 the system ``free()`` when all memory within an arena becomes unused
1487 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1488 freed. Some applications will see a drop in virtual memory size now,
1489 especially long-running applications that, from time to time, temporarily
1490 use a large number of small objects. Note that when Python returns an
1491 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001492 platform C library will in turn return that memory to the operating system.
1493 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001494 appears to be effective at least on Microsoft C and gcc-based systems.
1495 Thanks to Evan Jones for hard work and patience.
1496
Georg Brandl533ff6f2006-03-08 18:09:27 +00001497- Patch #1434038: property() now uses the getter's docstring if there is
1498 no "doc" argument given. This makes it possible to legitimately use
1499 property() as a decorator to produce a read-only property.
1500
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001501- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1502 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1503 of requiring an int or long in slicing and a few other contexts, enabling
1504 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1505
Neal Norwitz995acdf2006-03-07 05:01:00 +00001506- Fixed various bugs reported by Coverity's Prevent tool.
1507
Brett Cannonbf364092006-03-01 04:25:17 +00001508- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1509 new exception base class, BaseException, which has a new message attribute.
1510 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1511 Raising a string exception now raises a DeprecationWarning.
1512
Thomas Woutersfb609f42006-02-28 16:37:25 +00001513- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1514 explicitly relative, using 'from .module import name' to mean 'from the same
1515 package as this module is in. Imports without dots still default to the
1516 old relative-then-absolute, unless 'from __future__ import
1517 absolute_import' is used.
1518
Brett Cannona7446e32006-02-27 23:39:10 +00001519- Properly check if 'warnings' raises an exception (usually when a filter set
1520 to "error" is triggered) when raising a warning for raising string
1521 exceptions.
1522
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001523- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001524 The name was removed from Include/code.h.
1525
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001526- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001527
Guido van Rossum1968ad32006-02-25 22:38:04 +00001528- Patch 1433928:
1529 - The copy module now "copies" function objects (as atomic objects).
1530 - dict.__getitem__ now looks for a __missing__ hook before raising
1531 KeyError.
1532
Tim Peters84ef21c2006-02-28 20:39:06 +00001533- PEP 343: with statement implemented. Needs ``from __future__ import
1534 with_statement``. Use of 'with' as a variable will generate a warning.
1535 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001536 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001537 The following objects have __context__ methods:
1538 - The built-in file type.
1539 - The thread.LockType type.
1540 - The following types defined by the threading module:
1541 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1542 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001543
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001544- Fix the encodings package codec search function to only search
1545 inside its own package. Fixes problem reported in patch #1433198.
1546
1547 Note: Codec packages should implement and register their own
1548 codec search function. PEP 100 has the details.
1549
Tim Peters9ea89d22006-06-04 03:26:02 +00001550- PEP 353: Using ``Py_ssize_t`` as the index type.
1551
1552- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1553 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1554 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1555 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1556 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001557
Neal Norwitzfc76d632006-01-10 06:03:13 +00001558- Patch #1400181, fix unicode string formatting to not use the locale.
1559 This is how string objects work. u'%f' could use , instead of .
1560 for the decimal point. Now both strings and unicode always use periods.
1561
Neal Norwitz671b9e32006-01-09 07:07:12 +00001562- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1563 configure would break checking curses.h.
1564
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001565- Bug #959576: The pwd module is now builtin. This allows Python to be
1566 built on UNIX platforms without $HOME set.
1567
Neal Norwitzc10978f2005-12-19 06:07:16 +00001568- Bug #1072182, fix some potential problems if characters are signed.
1569
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001570- Bug #889500, fix line number on SyntaxWarning for global declarations.
1571
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001572- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1573
Neal Norwitze7214a12005-12-18 05:03:17 +00001574- Support for converting hex strings to floats no longer works.
1575 This was not portable. float('0x3') now raises a ValueError.
1576
Barry Warsaw2a38a862005-12-18 01:27:35 +00001577- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001578 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001579 is now displayed in interactive prompt banner.
1580
Georg Brandlfa166682005-12-17 21:45:17 +00001581- Implementation of PEP 341 - Unification of try/except and try/finally.
1582 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001583 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001584
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001585- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1586 now encodes backslash correctly.
1587
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001588- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1589
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001590- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001591 and long longs.
1592
Neal Norwitz67715f02005-11-09 06:59:35 +00001593- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001594 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001595 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001596
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001597- Replaced most Unicode charmap codecs with new ones using the
1598 new Unicode translate string feature in the builtin charmap
1599 codec; the codecs were created from the mapping tables available
1600 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1601 encodings now include a mapping for the Apple logo)
1602
Tim Peterse3547fd2005-12-16 23:13:57 +00001603- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001604
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001605- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001606
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001607- A new AST parser implementation was completed. The abstract
1608 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001609 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001610
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001611- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001612 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1613
Neal Norwitz708e51a2005-10-03 04:48:15 +00001614- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1615
Neal Norwitz11bd1192005-10-03 00:54:56 +00001616- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1617 Provide a warning when a directory is passed on the command line.
1618
Neal Norwitz40d37812005-10-02 01:48:49 +00001619- Fix segfault with invalid coding.
1620
1621- SF bug #772896: unknown encoding results in MemoryError.
1622
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001623- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001624 supported a __len__() method which evaluated to False when the iterator
1625 was empty.
1626
Guido van Rossum630db602005-09-20 18:49:54 +00001627- On 64-bit platforms, when __len__() returns a value that cannot be
1628 represented as a C int, raise OverflowError.
1629
Skip Montanarof8948ca2005-09-19 03:54:46 +00001630- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001631 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001632
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001633- SF bug #893549: parsing keyword arguments was broken with a few format
1634 codes.
1635
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001636- Changes donated by Elemental Security to make it work on AIX 5.3
1637 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1638 bug #105470: test_pwd fails on 64bit system (Opteron).
1639
Guido van Rossum539c6622005-09-14 17:49:54 +00001640- Changes donated by Elemental Security to make it work on HP-UX 11 on
1641 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1642
Georg Brandl4550b8d2005-08-26 06:43:52 +00001643- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001644 (fixes bug #1119418).
1645
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001646- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1647
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001648- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1649 exceptions that cause a function to exit.
1650
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001651- The implementation of set() and frozenset() was revised to use its
1652 own internal data structure. Memory consumption is reduced by 1/3
1653 and there are modest speed-ups as well. The API is unchanged.
1654
Tim Petersde7990b2005-07-17 23:45:23 +00001655- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1656
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001657- SF bug #1229429: PyObject_CallMethod failed to decrement some
1658 reference counts in some error exit cases.
1659
Tim Petersecc6e6a2005-07-10 22:30:55 +00001660- SF bug #1185883: Python's small-object memory allocator took over
1661 a block managed by the platform C library whenever a realloc specified
1662 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001663 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001664 portable way to copy data from the C-managed block into Python's
1665 small-object space without risking a memory fault. Python's small-object
1666 realloc now leaves such blocks under the control of the platform C
1667 realloc.
1668
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001669- SF bug #1232517: An overflow error was not detected properly when
1670 attempting to convert a large float to an int in os.utime().
1671
Raymond Hettinger3296e692005-06-29 23:29:56 +00001672- SF bug #1224347: hex longs now print with lowercase letters just
1673 like their int counterparts.
1674
Michael W. Hudson188d4362005-06-20 16:52:57 +00001675- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1676 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1677 interpreter states; back out that fix and do a better job (see
1678 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1679 for a longer write-up of the problem).
1680
Michael W. Hudsondf888462005-06-03 14:41:55 +00001681- SF patch #1180995: marshal now uses a binary format by default when
1682 serializing floats.
1683
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001684- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1685 the routines that promise to produce IEEE 754 binary representations
1686 of floats now simply copy bytes around.
1687
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001688- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1689 278.
1690
Brett Cannonc3647ac2005-04-26 03:45:26 +00001691- patch #1109424: int, long, float, complex, and unicode now check for the
1692 proper magic slot for type conversions when subclassed. Previously the
1693 magic slot was ignored during conversion. Semantics now match the way
1694 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001695 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001696 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001697 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001698
Barry Warsawc8d907c2005-04-19 23:43:40 +00001699- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1700 NULL, now raise an AttributeError when attempting to set or delete the
1701 attribute. Previously a TypeError was raised, but this was inconsistent
1702 with the equivalent pure-Python implementation.
1703
Michael W. Hudson774479c2005-04-18 08:46:17 +00001704- It is now safe to call PyGILState_Release() before
1705 PyEval_InitThreads() (note that if there is reason to believe there
1706 are multiple threads around you still must call PyEval_InitThreads()
1707 before using the Python API; this fix is for extension modules that
1708 have no way of knowing if Python is multi-threaded yet).
1709
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001710- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1711 disabled caused a crash.
1712
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001713- Bug #1165306: instancemethod_new allowed the creation of a method
1714 with im_class == im_self == NULL, which caused a crash when called.
1715
Tim Petersecc6e6a2005-07-10 22:30:55 +00001716- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001717 fixes the crash seen in bug #1165761
1718
Raymond Hettinger96229b12005-03-11 06:49:40 +00001719- Added two new builtins, any() and all().
1720
Brett Cannon409d8f22005-03-05 06:47:57 +00001721- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001722 (e.g., ``class C(): pass`` is no longer a syntax error).
1723 Patch #1176012 added support to the 'parser' module and 'compiler' package
1724 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001725
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001726- Patch #1115086: Support PY_LONGLONG in structmember.
1727
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001728- Bug #1155938: new style classes did not check that __init__() was
1729 returning None.
1730
Tim Petersecc6e6a2005-07-10 22:30:55 +00001731- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001732 ('\') with a specific error message.
1733
Martin v. Löwisff232d72005-03-03 09:24:38 +00001734- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1735
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001736- Bug #1124295: the __name__ attribute of file objects was
1737 inadvertently made inaccessible in restricted mode.
1738
Tim Petersecc6e6a2005-07-10 22:30:55 +00001739- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001740 an ferror() call.
1741
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001742- min() and max() now support key= arguments with the same meaning as in
1743 list.sort().
1744
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001745- The peephole optimizer now performs simple constant folding in expressions:
1746 (2+3) --> (5).
1747
Raymond Hettingera422c342005-01-11 03:03:27 +00001748- set and frozenset objects can now be marshalled. SF #1098985.
1749
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001750- Bug #1077106: Poor argument checking could cause memory corruption
1751 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001752
Jeremy Hyltonab630502005-02-04 18:44:06 +00001753- The parser did not complain about future statements in illegal
1754 positions. It once again reports a syntax error if a future
1755 statement occurs after anything other than a doc string.
1756
Neil Schemenauercf52c072005-08-12 17:34:58 +00001757- Change the %s format specifier for str objects so that it returns a
1758 unicode instance if the argument is not an instance of basestring and
1759 calling __str__ on the argument returns a unicode instance.
1760
Tim Petersf4e69282006-02-27 17:15:31 +00001761- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1762 current thread state when the auto-GIL-state machinery knows about
1763 it (since the thread state is being deleted, continuing to remember it
1764 can't help, but can hurt if another thread happens to get created with
1765 the same thread id).
1766
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001767Extension Modules
1768-----------------
1769
Georg Brandl43f08a82006-03-31 18:01:16 +00001770- Patch #1380952: fix SSL objects timing out on consecutive read()s
1771
Neal Norwitz05a45592006-03-20 06:30:08 +00001772- Patch #1309579: wait3 and wait4 were added to the posix module.
1773
Anthony Baxterfa869072006-03-20 05:21:58 +00001774- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1775 In addition, the existing ulaw code was updated.
1776
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001777- RFE #567972: Socket objects' family, type and proto properties are

Nick Coghlan43832302006-04-23 17:04:07 +00001961- PEP 338: new module runpy defines a run_module function to support
1962 executing modules which provide access to source code or a code object
1963 via the PEP 302 import mechanisms.
1964

1973 in attribute values.
1974
Anthony Baxterc51ee692006-04-01 00:57:31 +00001975- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001976 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001977 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001978 module will not be built.
1979
Tim Petersc17976e2006-04-01 00:26:53 +00001980- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1981 aren't officially supported here, and trying to use them will probably
1982 raise an exception some day. But dicts have been allowed, and "mostly
1983 worked", so support for them won't go away without warning.
1984
Georg Brandl338ef7d2006-03-31 18:42:16 +00001985- Bug #1445068: getpass.getpass() can now be given an explicit stream

2003
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002004- email 4.0 package now integrated. This is largely the same as the email 3.0
2005 package that was included in Python 2.3, except that PEP 8 module names are
2006 now used (e.g. mail.message instead of email.Message). The MIME classes
2007 have been moved to a subpackage (e.g. email.mime.text instead of
2008 email.MIMEText). The old names are still supported for now. Several
2009 deprecated Message methods have been removed and lots of bugs have been
2010 fixed. More details can be found in the email package documentation.
2011
Walter Dörwald40108c92006-03-27 08:15:44 +00002012- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2013 (a subclass of tuple) that provides incremental decoders and encoders
2014 (a way to use stateful codecs without the stream API). Python functions
2015 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2016 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2017 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002019- Patch #1359365: Calling next() on a closed StringIO.String object raises
2020 a ValueError instead of a StopIteration now (like file and cString.String do).

2098 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2099 Ronald L. Rivest offered this advice for Python:
2100
2101 "The consensus of researchers in this area (at least as
2102 expressed at the NIST Hash Function Workshop 10/31/05),
2103 is that SHA-256 is a good choice for the time being, but
2104 that research should continue, and other alternatives may
2105 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002106

2287 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002288 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002289 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002290 + Dialect parameter parsing has been re-implemented to improve error

2292 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2293 dictates.
2294 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002295 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002296 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002297 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields

Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002299 + reader now allows \r characters to be quoted (previously it only allowed
2300 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002301 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002302 + Dialect classes passed to the module are no longer instantiated by
2303 the module before being parsed (the former validation scheme required
2304 this, but the mechanism was unreliable).
2305 + The dialect registry now contains instances of the internal
2306 C-coded dialect type, rather than references to python objects.
2307 + the internal c-coded dialect type is now immutable.
2308 + register_dialect now accepts the same keyword dialect specifications
2309 as the reader and writer, allowing the user to register dialects
2310 without first creating a dialect class.
2311 + a configurable limit to the size of parsed fields has been added -
2312 previously, an unmatched quote character could result in the entire
2313 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002314 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002315 the parser field size limit (returning the former limit). The initial
2316 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002317 + A line_num attribute has been added to the reader object, which tracks
2318 the number of lines read from the source iterator. This is not
2319 the same as the number of records returned, as records can span
2320 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002321 + reader and writer objects were not being registered with the cyclic-GC.
2322 This has been fixed.
2323
Brett Cannone6539c42005-01-08 02:43:53 +00002324- _DummyThread objects in the threading module now delete self.__block that is
2325 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2326 lock primitives tend to be limited in number and thus should not be wasted on
2327 a _DummyThread object. Fixes bug #1089632.
2328
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002329- The imghdr module now detects Exif files.
2330
Raymond Hettinger6065d322004-12-20 23:51:53 +00002331- StringIO.truncate() now correctly adjusts the size attribute.
2332 (Bug #951915).
2333
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002334- locale.py now uses an updated locale alias table (built using
2335 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2336 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002337 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002338
Raymond Hettinger3557f422004-12-07 12:02:02 +00002339- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2340
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002341- the pickle module no longer accepts the deprecated None option in the
2342 args tuple returned by __reduce__().
2343
Brett Cannon84667c02004-12-07 03:25:18 +00002344- optparse now optionally imports gettext. This allows its use in setup.py.
2345
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002346- the pickle module no longer uses the deprecated bin parameter.
2347
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002348- the shelve module no longer uses the deprecated binary parameter.
2349
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002350- the pstats module no longer uses the deprecated ignore() method.
2351
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002352- the filecmp module no longer uses the deprecated use_statcache argument.
2353
Raymond Hettinger664347b2004-12-04 21:21:53 +00002354- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2355 extended or overridden by subclasses. Formerly, the subclassed method would
2356 be ignored by the rest of the module. (Bug #1078905).
2357
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002358- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002359 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002360
Walter Dörwald36733692004-12-22 12:50:50 +00002361- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2362 once when a size argument is given. This prevents a buffer overflow in the
2363 tokenizer with very long source lines.
2364
Barry Warsaw538561e2006-01-01 21:48:54 +00002365- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2366 immediately after creating the object, without any intervening
2367 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002368
Skip Montanaro05885812005-01-16 20:48:27 +00002369- The reconvert.quote function can now emit triple-quoted strings. The
2370 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002371
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002372- ``UserString.MutableString`` now supports negative indices in
2373 ``__setitem__`` and ``__delitem__``
2374
Greg Ward40407942005-03-05 02:53:17 +00002375- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2376 correctly.
2377
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002378- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2379 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2380 character even if the user has passed a size parameter to get a proper
2381 line ending. Remove the special handling of a "\r\n" that has been split
2382 between two lines.
2383
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002384- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2385 about illegal code points. The codec now supports PEP 293 style error
2386 handlers.
2387
Walter Dörwald78a78b02005-09-01 12:04:29 +00002388- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002389 from the input stream, so that the output is a byte string in the correct
2390 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002391
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002392- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2393 considering it exactly like a '*'.
2394
Walter Dörwald007f8df2005-10-09 19:42:27 +00002395- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2396 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002397
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002398- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2399
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002400- Patch #1413711: Certain patterns of differences were making difflib
2401 touch the recursion limit.
2402
Walter Dörwald58917a62006-03-31 15:26:22 +00002403- Bug #947906: An object oriented interface has been added to the calendar
2404 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002405 called as a script (e.g. via ``python -mcalendar``). Localized month and
2406 weekday names can be ouput (even if an exotic encoding is used) using
2407 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002408
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002409Build
2410-----
2411
Neal Norwitz602d3392006-03-31 08:21:40 +00002412- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2413 by using -mieee gcc option.
2414
Martin v. Löwis86d66262006-02-17 08:40:11 +00002415- Patch #1432345: Make python compile on DragonFly.
2416
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002417- Build support for Win64-AMD64 was added.
2418
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002419- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2420
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002421- Patch #881820: look for openpty and forkpty also in libbsd.
2422
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002423- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2424 The zlib module is now builtin on Windows.
2425
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002426- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2427
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002428- Bug #1189330: configure did not correctly determine the necessary
2429 value of LINKCC if python was built with GCC 4.0.
2430
Trent Mick8321b422005-07-26 02:29:21 +00002431- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2432 vulnerability in zlib 1.2.1 and 1.2.2.
2433
Brett Cannon08cd5982005-04-24 22:26:38 +00002434- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2435 flags that change binary compatibility. Changes were also made to
2436 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002437 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002438
Bob Ippolitoed233462005-03-29 13:47:59 +00002439- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2440 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2441 no longer exists). This configure patch makes things right.
2442
Martin v. Löwise2713be2005-03-08 15:03:08 +00002443- Bug #1158607: Build with --disable-unicode again.
2444
Brett Cannon46d96232005-02-16 00:07:19 +00002445- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2446 defined. Discovered as a result of not being able to build on OS X.
2447
Brett Cannon516592f2004-12-07 00:42:59 +00002448- setup.py now uses the directories specified in LDFLAGS using the -L option
2449 and in CPPFLAGS using the -I option for adding library and include
2450 directories, respectively, for compiling extension modules against. This has
2451 led to the core being compiled using the values in CPPFLAGS. It also removes
2452 the need for the special-casing of both DarwinPorts and Fink for darwin since
2453 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2454 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2455 Fink, ``-I/opt/local/include`` for DarwinPorts).
2456
Brett Cannon43802422005-02-10 20:48:03 +00002457- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2458 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2459 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2460 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002462C API
2463-----
2464
Tim Petersc9d78aa2006-03-26 23:27:58 +00002465- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2466 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2467 is obtained via the ``PyObject_`` family, it must be released via the
2468 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2469 always been officially true, but when Python's small-object allocator was
2470 introduced, an attempt was made to cater to a few extension modules
2471 discovered at the time that obtained memory via ``PyObject_New`` but
2472 released it via ``PyMem_DEL``. It's years later, and if such code still
2473 exists it will fail now (probably with segfaults, but calling wrong
2474 low-level memory management functions can yield many symptoms).
2475
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002476- Added a C API for set and frozenset objects.
2477
Raymond Hettinger66517482004-12-03 11:45:13 +00002478- Removed PyRange_New().
2479
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002480- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2481 mapping argument now. This string is used as a mapping table. Byte values
2482 greater than the length of the string and 0xFFFE are treated as undefined
2483 mappings.
