322
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000323- The return tuple from str.rpartition(sep) is (tail, sep, head) where
324 head is the original string if sep was not found.
325
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000326- Bug #1520864: unpacking singleton tuples in list comprehensions and
327 generator expressions (x for x, in ... ) works again. Fixing this problem
328 required changing the .pyc magic number. This means that .pyc files
329 generated before 2.5c2 will be regenerated.

429Core and builtins
430-----------------
431
Neal Norwitz24b6f202006-09-05 04:43:56 +0000432- Fix infinite recursion when subclassing long and overriding __hash__.
433
434- Fix concatenation (+=) of long strings.
435
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000436- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000437 compared equal or unequal to a string and a UnicodeDecodeError
438 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000439
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000440 Instead, the equal (==) and unequal (!=) comparison operators will
441 now issue a UnicodeWarning and interpret the two objects as
442 unequal. The UnicodeWarning can be filtered as desired using
443 the warning framework, e.g. silenced completely, turned into an
444 exception, logged, etc.
445
446 Note that compare operators other than equal and unequal will still
447 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000448
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000449- Fix segfault when doing string formatting on subclasses of long.
450
451- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
452 with new-style classes.
453
454- Fix bug related to __len__ functions returning negative values with
455 classic classes.
456
457- Patch #1538606, Fix __index__() clipping. There were some problems
458 discovered with the API and how integers that didn't fit into Py_ssize_t
459 were handled. This patch attempts to provide enough alternatives
460 to effectively use __index__.
461
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000462- Bug #1536021: __hash__ may now return long int; the final hash
463 value is obtained by invoking hash on the long int.
464
Thomas Hellerab1049c2006-08-08 17:37:00 +0000465- Bug #1536786: buffer comparison could emit a RuntimeWarning.

468 sys.stdin is closed.
469
Thomas Heller74d36f02006-08-04 18:17:40 +0000470- On Windows, the PyErr_Warn function is now exported from
471 the Python dll again.
472
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000473- Bug #1191458: tracing over for loops now produces a line event
474 on each iteration. Fixing this problem required changing the .pyc
475 magic number. This means that .pyc files generated before 2.5c1
476 will be regenerated.
477
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000478- Bug #1333982: string/number constants were inappropriately stored
479 in the byte code and co_consts even if they were not used, ie
480 immediately popped off the stack.
481
Georg Brandle9462c72006-08-04 18:03:37 +0000482- Fixed a reference-counting problem in property().

485Library
486-------
487
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000488- Fix a bug in the ``compiler`` package that caused invalid code to be
489 generated for generator expressions.
490
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000491- The distutils version has been changed to 2.5.0. The change to
492 keep it programmatically in sync with the Python version running
493 the code (introduced in 2.5b3) has been reverted. It will continue
494 to be maintained manually as static string literal.
495
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000496- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000497 and this cannot be converted to the required C type, an exception is
498 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000499 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000500
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000501- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000502 an exception.
503
Tim Peterscbdd3502006-09-05 01:47:53 +0000504- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000505 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000506 workarounds for clocks with low resolution, to stop the code yielding
507 duplicate UUIDs.
508
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000509- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
510 before raising SystemExit, allowing IDLE to honor quit() and exit().
511
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000512- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
513
Georg Brandl7a1af772006-08-14 21:55:28 +0000514- Patch #1536071: trace.py should now find the full module name of a
515 file correctly even on Windows.
516
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000517- logging's atexit hook now runs even if the rest of the module has
518 already been cleaned up.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000522- Bug #1531405, format_exception no longer raises an exception if
523 str(exception) raised an exception.
524
Neil Schemenauer06ded092006-08-04 16:20:30 +0000525- Fix a bug in the ``compiler`` package that caused invalid code to be

541
Thomas Heller86720042006-08-14 11:17:48 +0000542- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now

544 function calls. The ctypes version number was changed to 1.0.1.
545
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000546- Bug #1530559, struct.pack raises TypeError where it used to convert.
547 Passing float arguments to struct.pack when integers are expected
548 now triggers a DeprecationWarning.

598Core and builtins
599-----------------
600
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000601- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000602 returned a long (see PEP 353).
603
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000604- Bug #1515471: string.replace() accepts character buffers again.
605
Neal Norwitz07aadb12006-07-30 06:55:48 +0000606- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
607 This provides the proper warning for struct.pack().
608 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
609
Neal Norwitz0d62a062006-07-30 06:53:31 +0000610- Patch #1531113: Fix augmented assignment with yield expressions.
611 Also fix a SystemError when trying to assign to yield expressions.
612
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000613- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
614 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
615 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
616 excessive filesystem operations during imports.
617
Tim Petersbc24eee2006-07-27 01:14:53 +0000618- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
619 operations on signed longs that are formally undefined by C.
620 Unfortunately, at least one compiler now cares about that, so complicated
621 the code to make that compiler happy again.
622
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000623- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
624
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000625- Patch #1232023: Stop including current directory in search
626 path on Windows.
627

629
Neal Norwitze7563102006-07-17 01:00:16 +0000630- Fix warnings reported by Klocwork's static analysis tool.
631
Neal Norwitz84be93b2006-07-16 01:50:38 +0000632- Bug #1512814, Fix incorrect lineno's when code within a function
633 had more than 255 blank lines.
634
Georg Brandl9dceedb2006-07-12 15:31:17 +0000635- Patch #1521179: Python now accepts the standard options ``--help`` and
636 ``--version`` as well as ``/?`` on Windows.
637
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000638- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000639 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000640 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000641
Tim Peters112aad32006-07-19 00:03:19 +0000642- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000643 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000644 new ``sys._current_frames()`` returns a dictionary with one entry,
645 mapping the faux "thread id" 0 to the current frame.
646
Ronald Oussoren3075e162006-07-25 20:28:55 +0000647- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

651-------
652
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000653- Correction of patch #1455898: In the mbcs decoder, set final=False
654 for stream decoder, but final=True for the decode function.
655
Georg Brandl07fec3a2006-08-01 18:49:24 +0000656- os.urandom no longer masks unrelated exceptions like SystemExit or
657 KeyboardInterrupt.
658
Tim Peters4643c2f2006-08-10 22:45:34 +0000659- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000660 shutil.copytree on Windows
661
Georg Brandle34ac7c2006-07-30 11:07:23 +0000662- Bug #1002398: The documentation for os.path.sameopenfile now correctly
663 refers to file descriptors, not file objects.
664
Tim Peterscbdd3502006-09-05 01:47:53 +0000665- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000666 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000667 #1513611, and probably others.
668
Georg Brandledd9b0d2006-07-29 09:33:26 +0000669- Bug #1441397: The compiler module now recognizes module and function
670 docstrings correctly as it did in Python 2.4.
671
Tim Peters6f681472006-07-27 23:44:37 +0000672- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
673 lost that tests are sorted by name before being run. This rarely
674 matters for well-written tests, but can create baffling symptoms if
675 side effects from one test to the next affect outcomes. ``DocTestFinder``
676 has been changed to sort the list of tests it returns.
677
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000678- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000679 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000680
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000681- Bug #978833: Really close underlying socket in _socketobject.close.
682
Georg Brandldb232dc2006-08-20 13:15:43 +0000683- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
684 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000685
Georg Brandlcf0c1722006-07-26 07:23:32 +0000686- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
687 to recursive calls and call it with the failing package name.
688
Martin v. Löwis0b483032006-07-25 09:53:12 +0000689- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
690
Georg Brandlc13c34c2006-07-24 14:09:56 +0000691- Patch #1515343: Fix printing of deprecated string exceptions with a
692 value in the traceback module.
693
Greg Ward48fae7a2006-07-23 16:05:51 +0000694- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
695
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000696- Patch #1524429: Use repr() instead of backticks in Tkinter again.
697
Brett Cannoncaebe222006-07-18 04:41:36 +0000698- Bug #1520914: Change time.strftime() to accept a zero for any position in its
699 argument tuple. For arguments where zero is illegal, the value is forced to
700 the minimum value that is correct. This is to support an undocumented but
701 common way people used to fill in inconsequential information in the time
702 tuple pre-2.4.
703
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000704- Patch #1220874: Update the binhex module for Mach-O.
705
Barry Warsawb110bad2006-07-21 14:51:07 +0000706- The email package has improved RFC 2231 support, specifically for
707 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
708 (name*0=<blah>) parameter continuations. This may change the types of
709 values returned from email.message.Message.get_param() and friends.
710 Specifically in some cases where non-encoded continuations were used,
711 get_param() used to return a 3-tuple of (None, None, string) whereas now it
712 will just return the string (since non-encoded continuations don't have
713 charset and language parts).
714
715 Also, whereas % values were decoded in all parameter continuations, they are
716 now only decoded in encoded parameter parts.
717
Ronald Oussoren3075e162006-07-25 20:28:55 +0000718- Bug #1517990: IDLE keybindings on MacOS X now work correctly
719
720- Bug #1517996: IDLE now longer shows the default Tk menu when a
721 path browser, class browser or debugger is the frontmost window on MacOS X
722
Barry Warsaw00decd72006-07-27 23:43:15 +0000723- Patch #1520294: Support for getset and member descriptors in types.py,
724 inspect.py, and pydoc.py. Specifically, this allows for querying the type
725 of an object against these built-in types and more importantly, for getting
726 their docstrings printed in the interactive interpreter's help() function.

730-----------------
731
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000732- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
733 a socket operation on a socket with a timeout, the exception will be
734 caught correctly. Previously, the exception was not caught.
735
Thomas Heller1393d6a2006-07-28 21:43:20 +0000736- Patch #1529514: The _ctypes extension is now compiled on more
737 openbsd target platforms.
738
Tim Peters9cab5932006-07-28 00:30:00 +0000739- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
740 a memory leak, affecting pickles and deep copies.
741
Tim Petersbc24eee2006-07-27 01:14:53 +0000742- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000743 Paul Eggert.
744
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000745- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
746
Thomas Hellerce049a02006-07-14 17:51:14 +0000747- Patch #1521817: Index range checking on ctypes arrays containing
748 exactly one element enabled again. This allows iterating over these
749 arrays, without the need to check the array size before.
750
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000751- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000752 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000753 /dev/null in certain cases; this is now fixed.
754
Thomas Heller47d7a062006-07-12 08:43:47 +0000755- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
756 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000757
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000758- Because of a misspelled preprocessor symbol, ctypes was always
759 compiled without thread support; this is now fixed.
760
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000761- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
762 methods now allow their database parameter to be None as the
763 sleepycat API allows.
764
Matt Flemingec926502006-07-28 11:27:27 +0000765- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
766 bluetooth API compared with Linux and FreeBSD.
767
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000768Tests
769-----
770
771- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
772 how long the test file should take to play. Now accepts taking 2.93 secs
773 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
774
Georg Brandl4793aa32006-07-28 18:31:39 +0000775- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
776 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
777 run via ``regrtest.py``. Now they do.

783
Ronald Oussoren26cad082006-08-01 21:00:57 +0000784Mac
785---
786
787- PythonLauncher now works correctly when the path to the script contains
788 characters that are treated specially by the shell (such as quotes).
789
790- Bug #1527397: PythonLauncher now launches scripts with the working directory
791 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000792 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000793 expect.

801Core and builtins
802-----------------
803
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000804- Bug #1441486: The literal representation of -(sys.maxint - 1)
805 again evaluates to a int object, not a long.
806
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000807- Bug #1501934: The scope of global variables that are locally assigned
808 using augmented assignment is now correctly determined.
809
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000810- Bug #927248: Recursive method-wrapper objects can now safely
811 be released.
812
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000813- Bug #1417699: Reject locale-specific decimal point in float()
814 and atof().
815
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000816- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
817 omit a default "error" argument for NULL pointer. This allows
818 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000819
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000820- Bug #1519018: 'as' is now validated properly in import statements.
821
Neal Norwitz28746ab2006-07-09 22:14:42 +0000822- On 64 bit systems, int literals that use less than 64 bits are
823 now ints rather than longs.
824
Neal Norwitzed657552006-07-10 00:04:44 +0000825- Bug #1512814, Fix incorrect lineno's when code at module scope
826 started after line 256.
827
Tim Peters32a83612006-07-10 21:08:24 +0000828- New function ``sys._current_frames()`` returns a dict mapping thread
829 id to topmost thread stack frame. This is for expert use, and is
830 especially useful for debugging application deadlocks. The functionality
831 was previously available in Fazal Majid's ``threadframe`` extension
832 module, but it wasn't possible to do this in a wholly threadsafe way from
833 an extension.

842
Tim Peters32a83612006-07-10 21:08:24 +0000843- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000844 environment variable to be set in order to the SDK environment
845 for finding the compiler, include files, etc.

850
Thomas Woutersadd19112006-07-05 11:03:49 +0000851- string.Template() now correctly handles tuple-values. Previously,
852 multi-value tuples would raise an exception and single-value tuples would
853 be treated as the value they contain, instead.
854
Martin v. Löwisede77f52006-07-03 13:01:35 +0000855- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

862 degrees and radians.
863
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000864- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000865 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000866
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000867- Bug #1514703: Only setup canvas window in turtle when the canvas
868 is created.
869
Martin v. Löwis7596e832006-07-01 15:33:37 +0000870- Bug #1513223: .close() of a _socketobj now releases the underlying
871 socket again, which then gets closed as it becomes unreferenced.
872
Fred Drake10497c82006-06-29 02:57:48 +0000873- Bug #1504333: Make sgmllib support angle brackets in quoted
874 attribute values.
875
876- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
877 sgmllib ('[' and ']' were not accepted).
878
Georg Brandl1be63af2006-06-28 20:23:25 +0000879- Fix a bug in the turtle module's end_fill function.
880
Brett Cannon53ab5b72006-06-22 16:49:14 +0000881- Bug #1510580: The 'warnings' module improperly required that a Warning
882 category be either a types.ClassType and a subclass of Warning. The proper
883 check is just that it is a subclass with Warning as the documentation states.
884
Georg Brandlad29e632006-06-21 17:45:17 +0000885- The compiler module now correctly compiles the new try-except-finally
886 statement (bug #1509132).
887
Neal Norwitz60373cd2006-06-22 06:30:50 +0000888- The wsgiref package is now installed properly on Unix.
889
Vinay Sajip28e57612006-07-01 10:45:20 +0000890- A bug was fixed in logging.config.fileConfig() which caused a crash on
891 shutdown when fileConfig() was called multiple times.
892
Gerhard Häring762fbd32006-07-02 17:48:30 +0000893- The sqlite3 module did cut off data from the SQLite database at the first
894 null character before sending it to a custom converter. This has been fixed
895 now.

899
Tim Peters112aad32006-07-19 00:03:19 +0000900- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
901 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
902 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000903
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000904- Assigning None to pointer type fields in ctypes structures possible
905 overwrote the wrong fields, this is fixed now.
906
907- Fixed a segfault in _ctypes when ctypes.wintypes were imported
908 on non-Windows platforms.
909
910- Bug #1518190: The ctypes.c_void_p constructor now accepts any
911 integer or long, without range checking.
912
913- Patch #1517790: It is now possible to use custom objects in the ctypes
914 foreign function argtypes sequence as long as they provide a from_param
915 method, no longer is it required that the object is a ctypes type.
916
917- The '_ctypes' extension module now works when Python is configured
918 with the --without-threads option.
919
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000920- Bug #1513646: os.access on Windows now correctly determines write
921 access, again.
922
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000923- Bug #1512695: cPickle.loads could crash if it was interrupted with
924 a KeyboardInterrupt.
925
Neal Norwitza12aa882006-07-06 06:45:08 +0000926- Bug #1296433: parsing XML with a non-default encoding and
927 a CharacterDataHandler could crash the interpreter in pyexpat.

935
Tim Peters32a83612006-07-10 21:08:24 +0000936- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000937 Previously, the slight difference could cause compilation errors of the
938 'zlib' module on systems with more than one version of zlib.
939
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000940- The MSI compileall step was fixed to also support a TARGETDIR

944 of Tcl/Tk.
945
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000946- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000947 trying to be installed even though it's empty.

950-----
951
952- Call os.waitpid() at the end of tests that spawn child processes in order
953 to minimize resources (zombies).

956-------------
957
Nick Coghlan2d792252006-07-06 13:47:18 +0000958- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
959 documentation for the warnings module.
960
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000961- Patch #1509163: MS Toolkit Compiler no longer available.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000966What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000967================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000968
Anthony Baxterd1136802006-06-19 12:04:15 +0000969*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000970
971Core and builtins
972-----------------
973
Georg Brandla56b9152006-06-19 06:35:54 +0000974- Patch #1507676: Error messages returned by invalid abstract object operations
975 (such as iterating over an integer) have been improved and now include the
976 type of the offending object to help with debugging.
977
Brett Cannonea3912b2006-06-13 21:46:41 +0000978- Bug #992017: A classic class that defined a __coerce__() method that returned
979 its arguments swapped would infinitely recurse and segfault the interpreter.
980
Neal Norwitz909eb122006-06-12 02:13:21 +0000981- Fix the socket tests so they can be run concurrently.
982
Neal Norwitzb9845e72006-06-12 02:11:18 +0000983- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000984 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000985
Brett Cannon22565aa2006-06-09 22:31:23 +0000986- Bug #532646: object.__call__() will continue looking for the __call__
987 attribute on objects until one without one is found. This leads to recursion
988 when you take a class and set its __call__ attribute to an instance of the
989 class. Originally fixed for classic classes, but this fix is for new-style.
990 Removes the infinite_rec_3 crasher.
991
Georg Brandl24250812006-06-09 18:45:48 +0000992- The string and unicode methods startswith() and endswith() now accept
993 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
994
Brett Cannonde3b0522006-06-08 17:00:45 +0000995- Buffer objects, at the C level, never used the char buffer
996 implementation even when the char buffer for the wrapped object was
997 explicitly requested (originally returned the read or write buffer).
998 Now a TypeError is raised if the char buffer is not present but is
999 requested.
1000
Georg Brandlddbaa662006-06-04 21:56:52 +00001001- Patch #1346214: Statements like "if 0: suite" are now again optimized
1002 away like they were in Python 2.4.
1003
Georg Brandlb7c8f542006-05-27 12:30:25 +00001004- Builtin exceptions are now full-blown new-style classes instead of
1005 instances pretending to be classes, which speeds up exception handling
1006 by about 80% in comparison to 2.5a2.
1007
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001008- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1009 Unicode 4.1.
1010
Georg Brandlf4ef1162006-05-26 18:03:31 +00001011- Patch #921466: sys.path_importer_cache is now used to cache valid and
1012 invalid file paths for the built-in import machinery which leads to
1013 fewer open calls on startup.
1014
Tim Peters696cf432006-05-24 21:10:40 +00001015- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1016 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1017 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1018 the number of input digits (it was and remains linear-time for bases
1019 2, 4, 8, 16 and 32).
1020
Tim Petersb713ec22006-05-23 18:45:30 +00001021- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1022 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1023 an integer close to ``sys.maxint``. This was repaired by patch
1024 #1335972, which also gives a nice speedup.
1025
Richard Jonescebbefc2006-05-23 18:28:17 +00001026- Patch #1337051: reduced size of frame objects.
1027
1028- PyErr_NewException now accepts a tuple of base classes as its
1029 "base" parameter.
1030
Richard Jones7c88dcc2006-05-23 10:37:38 +00001031- Patch #876206: function call speedup by retaining allocated frame
1032 objects.
1033
Georg Brandl7b90e162006-05-18 07:01:27 +00001034- Bug #1462152: file() now checks more thoroughly for invalid mode
1035 strings and removes a possible "U" before passing the mode to the
1036 C library function.
1037
Neal Norwitz1004a532006-05-15 07:17:23 +00001038- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1039
Neal Norwitz373f0a72006-05-15 07:04:36 +00001040- Bug #1487966: Fix SystemError with conditional expression in assignment
1041
Martin v. Löwis879768d2006-05-11 13:28:43 +00001042- WindowsError now has two error code attributes: errno, which carries
1043 the error values from errno.h, and winerror, which carries the error
1044 values from winerror.h. Previous versions put the winerror.h values
1045 (from GetLastError()) into the errno attribute.
1046
Martin v. Löwis77736712006-05-04 05:51:03 +00001047- Patch #1475845: Raise IndentationError for unexpected indent.
1048
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001049- Patch #1479181: split open() and file() from being aliases for each other.
1050
Tim Peters44bd9862006-06-01 13:49:23 +00001051- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1052 methods were always silently ignored by dictionaries when comparing keys.
1053 They are now passed through (except when using the C API function
1054 ``PyDict_GetItem()``, whose semantics did not change).
1055
1056- Bug #1456209: In some obscure cases it was possible for a class with a
1057 custom ``__eq__()`` method to confuse dict internals when class instances
1058 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1059 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001061Extension Modules
1062-----------------
1063
Trent Mick960a3f82006-06-28 20:30:41 +00001064- Bug #1295808: expat symbols should be namespaced in pyexpat
1065
1066- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1067
Brett Cannon6ee7d012006-06-08 16:23:04 +00001068- Change binascii.hexlify to accept a read-only buffer instead of only a char
1069 buffer and actually follow its documentation.
1070
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001071- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1072
Nick Coghlanc649ec52006-05-29 12:43:05 +00001073- Patch #1478788 (modified version): The functional extension module has
1074 been renamed to _functools and a functools Python wrapper module added.
1075 This provides a home for additional function related utilities that are
1076 not specifically about functional programming. See PEP 309.
1077
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001078- Patch #1493701: performance enhancements for struct module.
1079
Georg Brandl378d5922006-05-17 14:26:50 +00001080- Patch #1490224: time.altzone is now set correctly on Cygwin.
1081
Georg Brandl8d3342b2006-05-16 07:38:27 +00001082- Patch #1435422: zlib's compress and decompress objects now have a
1083 copy() method.
1084
Andrew MacIntyre92913322006-06-13 15:04:24 +00001085- Patch #1454481: thread stack size is now tunable at runtime for thread
1086 enabled builds on Windows and systems with Posix threads support.
1087
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001088- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1089 (up to the system limit of 32K characters).
1090
1091- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1092 As a result, these functions now raise WindowsError instead of OSError.
1093
Tim Peters7a822da2006-05-25 21:50:17 +00001094- ``time.clock()`` on Win64 should use the high-performance Windows
1095 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1096 Windows platforms).
1097
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001098- Calling Tk_Init twice is refused if the first call failed as that
1099 may deadlock.
1100
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001101- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1102 accept it without potentially using an uninitialized pointer.
1103
1104- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1105 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1106 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001107
Gregory P. Smith372b5832006-06-05 18:48:21 +00001108- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001109 [pybsddb project SF patch number 1466734]
1110
Gregory P. Smith372b5832006-06-05 18:48:21 +00001111- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1112 parameter is supplied. [SF pybsddb bug #1477863]
1113
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001114- bsddb: the __len__ method of a DB object has been fixed to return correct
1115 results. It could previously incorrectly return 0 in some cases.
1116 Fixes SF bug 1493322 (pybsddb bug 1184012).
1117
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001118- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1119 aborts the db transaction safely when a modifier callback fails.
1120 Fixes SF python patch/bug #1408584.
1121
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001122- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001123 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001124 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1125 database calls that would previously deadlock. [SF python bug #775414]
1126
Vinay Sajip28e57612006-07-01 10:45:20 +00001127- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001128
Walter Dörwald4994d952006-06-19 08:07:50 +00001129- Patch #1506645: add Python wrappers for the curses functions
1130 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001131

1133-------
1134
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001135- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1136 functions.
1137
Martin v. Löwis3798da02006-06-17 18:44:27 +00001138- Patch #812986: Update turtle output even if not tracing.
1139
Vinay Sajip28e57612006-07-01 10:45:20 +00001140- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001141 Tkinter.BaseWidget.
1142
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001143- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1144
Martin v. Löwis337487e2006-06-17 09:15:14 +00001145- Patch #763580: Add name and value arguments to Tkinter variable
1146 classes.
1147
Georg Brandl83cc0d02006-06-14 08:50:03 +00001148- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1149 mime.types file for determining MIME types.
1150
Georg Brandl2605ca82006-06-14 06:08:31 +00001151- Bug #1339007: Shelf objects now don't raise an exception in their
1152 __del__ method when initialization failed.
1153
Martin v. Löwisd8251432006-06-14 05:21:04 +00001154- Patch #1455898: The MBCS codec now supports the incremental mode for
1155 double-byte encodings.
1156
Tim Peters43898b42006-06-14 04:09:25 +00001157- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1158 guarantee that adjacent triples in the return list always describe
1159 non-adjacent blocks. Previously, a pair of matching blocks could end
1160 up being described by multiple adjacent triples that formed a partition
1161 of the matching pair.
1162
Greg Ward0e0c9f42006-06-11 16:24:11 +00001163- Bug #1498146: fix optparse to handle Unicode strings in option help,
1164 description, and epilog.
1165
Greg Wardd1c797e2006-06-11 14:42:41 +00001166- Bug #1366250: minor optparse documentation error.
1167
Greg Ward7f547402006-06-11 00:40:49 +00001168- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1169 clarify docs.
1170
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001171- The wsgiref package has been added to the standard library.
1172
Nick Coghlan676725d2006-06-08 13:54:49 +00001173- The functions update_wrapper() and wraps() have been added to the functools
1174 module. These make it easier to copy relevant metadata from the original
1175 function when writing wrapper functions.
1176
Tim Petersd6a9eef2006-06-05 01:48:21 +00001177- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1178 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001179
Martin v. Löwis3f767792006-06-04 19:36:28 +00001180- Patch #1359618: Speed up charmap encoder by using a trie structure
1181 for lookup.
1182
Tim Petersd609b1a2006-06-02 23:22:51 +00001183- The functions in the ``pprint`` module now sort dictionaries by key
1184 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1185 if and only if its display required more than one line, although that
1186 wasn't documented. The new behavior increases predictability; e.g.,
1187 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1188
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001189- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1190 (thanks for J. J. Lee).
1191
Georg Brandl2b330372006-05-28 20:23:12 +00001192- Patch #1496206: improve urllib2 handling of passwords with respect to
1193 default HTTP and HTTPS ports.
1194
George Yoshidaf3c65de2006-05-28 16:39:09 +00001195- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1196
Bob Ippolito7298f272006-05-23 18:43:47 +00001197- Patch #1281707: speed up gzip.readline.
1198
Georg Brandlb89316f2006-05-17 15:51:16 +00001199- Patch #1180296: Two new functions were added to the locale module:
1200 format_string() to get the effect of "format % items" but locale-aware,
1201 and currency() to format a monetary number with currency sign.
1202
Georg Brandle3a25832006-05-17 14:56:04 +00001203- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1204 and several features added, such as speed and geometry control.
1205
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001206- Patch #1488881: add support for external file objects in bz2 compressed
1207 tarfiles.
1208
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001209- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1210 stdout arguments, making it possible to redirect input and output
1211 for remote debugging.
1212
1213- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1214 a couple of issues, notably handling of long file names using the
1215 GNU LONGNAME extension.
1216
1217- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1218 new flag when ``name`` is already the name of an option flag.
1219
1220- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1221 package.
1222
1223- Patch #1472854: make the rlcompleter.Completer class usable on non-
1224 UNIX platforms.
1225
1226- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1227
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001228- Bug #1472827: correctly escape newlines and tabs in attribute values in
1229 the saxutils.XMLGenerator class.

1258
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001259What's New in Python 2.5 alpha 2?
1260=================================
1261
1262*Release date: 27-APR-2006*
1263
1264Core and builtins
1265-----------------
1266
Thomas Heller1b046642006-04-18 18:51:06 +00001267- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1268 by converting these apis from macros into exported functions again:
1269
1270 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1271 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1272 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1273 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1274 PyRun_String Py_CompileString
1275
Martin v. Löwis45294a92006-04-18 06:24:08 +00001276- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1277
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001278- All uses of PyStructSequence_InitType have been changed to initialize
1279 the type objects only once, even if the interpreter is initialized
1280 multiple times.
1281
Neal Norwitz61546162006-04-14 05:20:28 +00001282- Bug #1454485, array.array('u') could crash the interpreter. This was
1283 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1284 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1285
1286- Py_UNICODE is unsigned. It was always documented as unsigned, but
1287 due to a bug had a signed value in previous versions.
1288
Tim Peters3a5e8b12006-04-11 01:44:07 +00001289- Patch #837242: ``id()`` of any Python object always gives a positive
1290 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1291 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001292 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001293 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001294
Tim Peters3a5e8b12006-04-11 01:44:07 +00001295 def __hash__(self):
1296 return id(self) # WRONG
1297
1298 because a hash result must be a (short) Python int but it was always
1299 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001300 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001301 was always usable as a hash value before this patch. That's no longer
1302 necessarily so.
1303
1304- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001305 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001306 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001307 #1454844)
1308
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001309- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1310 involving generators that have paused outside of any ``try`` or ``with``
1311 blocks. (In 2.5a1, a paused generator that was part of a reference
1312 cycle could not be garbage collected, regardless of whether it was
1313 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001314
Anthony Baxter51bcb682006-04-05 14:51:42 +00001315Extension Modules
1316-----------------
1317
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001318- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1319 is a macro.
1320
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001321- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1322 fails with an error condition.
1323
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001324- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1325
1326- Bug #1117761: bsddb.*open() no longer raises an exception when using
1327 the cachesize parameter.
1328
1329- Bug #1149413: bsddb.*open() no longer raises an exception when using
1330 a temporary db (file=None) with the 'n' flag to truncate on open.
1331
1332- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1333 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001334
Armin Rigoa9017c32006-04-19 11:50:27 +00001335- Patch #1062014: AF_UNIX sockets under Linux have a special
1336 abstract namespace that is now fully supported.
1337
Anthony Baxter51bcb682006-04-05 14:51:42 +00001338Library
1339-------
1340
Peter Astrand7d1d4362006-07-14 14:04:45 +00001341- Bug #1223937: subprocess.CalledProcessError reports the exit status
1342 of the process using the returncode attribute, instead of
1343 abusing errno.
1344
Tim Peters711bf302006-04-25 03:31:36 +00001345- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1346 a doctest to be skipped (the code is not run, and the expected output
1347 or exception is ignored).
1348
Nick Coghlanda2268f2006-04-24 04:37:15 +00001349- Fixed contextlib.nested to cope with exceptions being raised and
1350 caught inside exit handlers.
1351
Greg Wardab05edc2006-04-23 03:47:58 +00001352- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1353 hex, octal, or binary; add ``append_const`` action; keep going if
1354 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1355 added ``epilog`` for better help generation).
1356
Tim Peters21fbd572006-04-21 21:18:10 +00001357- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1358 called from a thread spawned as a side effect of importing a module.
1359
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001360- The pydoc module now supports documenting packages contained in
1361 .zip or .egg files.
1362
1363- The pkgutil module now has several new utility functions, such
1364 as ``walk_packages()`` to support working with packages that are either
1365 in the filesystem or zip files.
1366
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001367- The mailbox module can now modify and delete messages from
1368 mailboxes, in addition to simply reading them. Thanks to Gregory
1369 K. Johnson for writing the code, and to the 2005 Google Summer of
1370 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001371
Tim Petersc7605f22006-04-17 21:12:33 +00001372- The ``__del__`` method of class ``local`` in module ``_threading_local``
1373 returned before accomplishing any of its intended cleanup.
1374
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001375- Patch #790710: Add breakpoint command lists in pdb.
1376
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001377- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1378
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001379- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1380
Anthony Baxtere29002c2006-04-12 12:07:31 +00001381- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1382 Windows. Bug #1469163.
1383
Phillip J. Eby47032112006-04-11 01:07:43 +00001384- The warnings, linecache, inspect, traceback, site, and doctest modules
1385 were updated to work correctly with modules imported from zipfiles or
1386 via other PEP 302 __loader__ objects.
1387
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001388- Patch #1467770: Reduce usage of subprocess._active to processes which
1389 the application hasn't waited on.
1390
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001391- Patch #1462222: Fix Tix.Grid.
1392
Neal Norwitza31bf182006-04-09 03:35:43 +00001393- Fix exception when doing glob.glob('anything*/')
1394
Skip Montanaro262fb922006-04-21 02:31:07 +00001395- The pstats.Stats class accepts an optional stream keyword argument to
1396 direct output to an alternate file-like object.
1397
Anthony Baxter51bcb682006-04-05 14:51:42 +00001398Build
1399-----
1400
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001401- The Makefile now has a reindent target, which runs reindent.py on
1402 the library.
1403
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001404- Patch #1470875: Building Python with MS Free Compiler
1405
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001406- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001407
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001408- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1409 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001410 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001411 CXX from --with-cxx-main, see description in README.
1412
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001413- Patch #1429775: Link extension modules with the shared libpython.
1414
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001415- Fixed a libffi build problem on MIPS systems.
1416
Tim Peters8931ff12006-05-13 23:28:20 +00001417- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1418 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1419 and "%zu" for unsigned integers of type ``size_t``.
1420
Anthony Baxter51bcb682006-04-05 14:51:42 +00001421Tests
1422-----
1423
Nick Coghlanda2268f2006-04-24 04:37:15 +00001424- test_contextlib now checks contextlib.nested can cope with exceptions
1425 being raised and caught inside exit handlers.
1426
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001427- test_cmd_line now checks operation of the -m and -c command switches
1428
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001429- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1430 it separately and by hand. It also wasn't cleaning up its changes to
1431 the current Decimal context.
1432
Thomas Woutersabd08882006-04-26 15:53:30 +00001433- regrtest.py now has a -M option to run tests that test the new limits of
1434 containers, on 64-bit architectures. Running these tests is only sensible
1435 on 64-bit machines with more than two gigabytes of memory. The argument
1436 passed is the maximum amount of memory for the tests to use.
1437
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001438Tools
1439-----
1440
1441- Added the Python benchmark suite pybench to the Tools/ directory;
1442 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001443
Anthony Baxter51bcb682006-04-05 14:51:42 +00001444Documentation
1445-------------
1446
Tim Petersb06d28c2006-05-12 01:57:59 +00001447- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1448
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001449- PEP 343: Added Context Types section to the library reference
1450 and attempted to bring other PEP 343 related documentation into
1451 line with the implementation and/or python-dev discussions.
1452
Tim Peters8dc73d22006-04-24 02:03:16 +00001453- Bug #1337990: clarified that ``doctest`` does not support examples
1454 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001457What's New in Python 2.5 alpha 1?
1458=================================
1459
Anthony Baxterebed3f62006-04-03 15:03:44 +00001460*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001461
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001462Core and builtins
1463-----------------
1464
Nick Coghlan43832302006-04-23 17:04:07 +00001465- PEP 338: -m command line switch now delegates to runpy.run_module
1466 allowing it to support modules in packages and zipfiles
1467
Martin v. Löwisc661b882006-04-20 04:54:23 +00001468- On Windows, .DLL is not an accepted file name extension for
1469 extension modules anymore; extensions are only found if they
1470 end in .PYD.
1471
Martin v. Löwisea62d252006-04-03 10:56:49 +00001472- Bug #1421664: sys.stderr.encoding is now set to the same value as
1473 sys.stdout.encoding.
1474
Neal Norwitz92e212f2006-04-03 04:48:37 +00001475- __import__ accepts keyword arguments.
1476
Georg Brandlccadf842006-03-31 18:54:53 +00001477- Patch #1460496: round() now accepts keyword arguments.
1478
Anthony Baxter262c00a2006-03-30 10:53:17 +00001479- Fixed bug #1459029 - unicode reprs were double-escaped.
1480
Hye-Shik Changd478f342006-03-23 12:32:36 +00001481- Patch #1396919: The system scope threads are reenabled on FreeBSD
1482 5.4 and later versions.
1483
Neal Norwitze98ccf62006-03-23 05:39:47 +00001484- Bug #1115379: Compiling a Unicode string with an encoding declaration
1485 now gives a SyntaxError.
1486
Georg Brandlabd1ff82006-03-18 07:59:59 +00001487- Previously, Python code had no easy way to access the contents of a
1488 cell object. Now, a ``cell_contents`` attribute has been added
1489 (closes patch #1170323).
1490
Tim Peterscf79aac2006-03-16 01:14:46 +00001491- Patch #1123430: Python's small-object allocator now returns an arena to
1492 the system ``free()`` when all memory within an arena becomes unused
1493 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1494 freed. Some applications will see a drop in virtual memory size now,
1495 especially long-running applications that, from time to time, temporarily
1496 use a large number of small objects. Note that when Python returns an
1497 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001498 platform C library will in turn return that memory to the operating system.
1499 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001500 appears to be effective at least on Microsoft C and gcc-based systems.
1501 Thanks to Evan Jones for hard work and patience.
1502
Georg Brandl533ff6f2006-03-08 18:09:27 +00001503- Patch #1434038: property() now uses the getter's docstring if there is
1504 no "doc" argument given. This makes it possible to legitimately use
1505 property() as a decorator to produce a read-only property.
1506
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001507- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1508 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1509 of requiring an int or long in slicing and a few other contexts, enabling
1510 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1511
Neal Norwitz995acdf2006-03-07 05:01:00 +00001512- Fixed various bugs reported by Coverity's Prevent tool.
1513
Brett Cannonbf364092006-03-01 04:25:17 +00001514- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1515 new exception base class, BaseException, which has a new message attribute.
1516 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1517 Raising a string exception now raises a DeprecationWarning.
1518
Thomas Woutersfb609f42006-02-28 16:37:25 +00001519- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1520 explicitly relative, using 'from .module import name' to mean 'from the same
1521 package as this module is in. Imports without dots still default to the
1522 old relative-then-absolute, unless 'from __future__ import
1523 absolute_import' is used.
1524
Brett Cannona7446e32006-02-27 23:39:10 +00001525- Properly check if 'warnings' raises an exception (usually when a filter set
1526 to "error" is triggered) when raising a warning for raising string
1527 exceptions.
1528
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001529- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001530 The name was removed from Include/code.h.
1531
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001532- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001533
Guido van Rossum1968ad32006-02-25 22:38:04 +00001534- Patch 1433928:
1535 - The copy module now "copies" function objects (as atomic objects).
1536 - dict.__getitem__ now looks for a __missing__ hook before raising
1537 KeyError.
1538
Tim Peters84ef21c2006-02-28 20:39:06 +00001539- PEP 343: with statement implemented. Needs ``from __future__ import
1540 with_statement``. Use of 'with' as a variable will generate a warning.
1541 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001542 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001543 The following objects have __context__ methods:
1544 - The built-in file type.
1545 - The thread.LockType type.
1546 - The following types defined by the threading module:
1547 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1548 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001549
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001550- Fix the encodings package codec search function to only search
1551 inside its own package. Fixes problem reported in patch #1433198.
1552
1553 Note: Codec packages should implement and register their own
1554 codec search function. PEP 100 has the details.
1555
Tim Peters9ea89d22006-06-04 03:26:02 +00001556- PEP 353: Using ``Py_ssize_t`` as the index type.
1557
1558- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1559 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1560 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1561 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1562 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001563
Neal Norwitzfc76d632006-01-10 06:03:13 +00001564- Patch #1400181, fix unicode string formatting to not use the locale.
1565 This is how string objects work. u'%f' could use , instead of .
1566 for the decimal point. Now both strings and unicode always use periods.
1567
Neal Norwitz671b9e32006-01-09 07:07:12 +00001568- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1569 configure would break checking curses.h.
1570
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001571- Bug #959576: The pwd module is now builtin. This allows Python to be
1572 built on UNIX platforms without $HOME set.
1573
Neal Norwitzc10978f2005-12-19 06:07:16 +00001574- Bug #1072182, fix some potential problems if characters are signed.
1575
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001576- Bug #889500, fix line number on SyntaxWarning for global declarations.
1577
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001578- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1579
Neal Norwitze7214a12005-12-18 05:03:17 +00001580- Support for converting hex strings to floats no longer works.
1581 This was not portable. float('0x3') now raises a ValueError.
1582
Barry Warsaw2a38a862005-12-18 01:27:35 +00001583- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001584 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001585 is now displayed in interactive prompt banner.
1586
Georg Brandlfa166682005-12-17 21:45:17 +00001587- Implementation of PEP 341 - Unification of try/except and try/finally.
1588 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001589 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001590
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001591- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1592 now encodes backslash correctly.
1593
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001594- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1595
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001596- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001597 and long longs.
1598
Neal Norwitz67715f02005-11-09 06:59:35 +00001599- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001600 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001601 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001602
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001603- Replaced most Unicode charmap codecs with new ones using the
1604 new Unicode translate string feature in the builtin charmap
1605 codec; the codecs were created from the mapping tables available
1606 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1607 encodings now include a mapping for the Apple logo)
1608
Tim Peterse3547fd2005-12-16 23:13:57 +00001609- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001610
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001611- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001612
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001613- A new AST parser implementation was completed. The abstract
1614 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001615 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001616
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001617- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001618 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1619
Neal Norwitz708e51a2005-10-03 04:48:15 +00001620- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1621
Neal Norwitz11bd1192005-10-03 00:54:56 +00001622- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1623 Provide a warning when a directory is passed on the command line.
1624
Neal Norwitz40d37812005-10-02 01:48:49 +00001625- Fix segfault with invalid coding.
1626
1627- SF bug #772896: unknown encoding results in MemoryError.
1628
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001629- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001630 supported a __len__() method which evaluated to False when the iterator
1631 was empty.
1632
Guido van Rossum630db602005-09-20 18:49:54 +00001633- On 64-bit platforms, when __len__() returns a value that cannot be
1634 represented as a C int, raise OverflowError.
1635
Skip Montanarof8948ca2005-09-19 03:54:46 +00001636- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001637 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001638
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001639- SF bug #893549: parsing keyword arguments was broken with a few format
1640 codes.
1641
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001642- Changes donated by Elemental Security to make it work on AIX 5.3
1643 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1644 bug #105470: test_pwd fails on 64bit system (Opteron).
1645
Guido van Rossum539c6622005-09-14 17:49:54 +00001646- Changes donated by Elemental Security to make it work on HP-UX 11 on
1647 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1648
Georg Brandl4550b8d2005-08-26 06:43:52 +00001649- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001650 (fixes bug #1119418).
1651
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001652- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1653
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001654- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1655 exceptions that cause a function to exit.
1656
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001657- The implementation of set() and frozenset() was revised to use its
1658 own internal data structure. Memory consumption is reduced by 1/3
1659 and there are modest speed-ups as well. The API is unchanged.
1660
Tim Petersde7990b2005-07-17 23:45:23 +00001661- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1662
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001663- SF bug #1229429: PyObject_CallMethod failed to decrement some
1664 reference counts in some error exit cases.
1665
Tim Petersecc6e6a2005-07-10 22:30:55 +00001666- SF bug #1185883: Python's small-object memory allocator took over
1667 a block managed by the platform C library whenever a realloc specified
1668 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001669 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001670 portable way to copy data from the C-managed block into Python's
1671 small-object space without risking a memory fault. Python's small-object
1672 realloc now leaves such blocks under the control of the platform C
1673 realloc.
1674
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001675- SF bug #1232517: An overflow error was not detected properly when
1676 attempting to convert a large float to an int in os.utime().
1677
Raymond Hettinger3296e692005-06-29 23:29:56 +00001678- SF bug #1224347: hex longs now print with lowercase letters just
1679 like their int counterparts.
1680
Michael W. Hudson188d4362005-06-20 16:52:57 +00001681- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1682 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1683 interpreter states; back out that fix and do a better job (see
1684 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1685 for a longer write-up of the problem).
1686
Michael W. Hudsondf888462005-06-03 14:41:55 +00001687- SF patch #1180995: marshal now uses a binary format by default when
1688 serializing floats.
1689
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001690- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1691 the routines that promise to produce IEEE 754 binary representations
1692 of floats now simply copy bytes around.
1693
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001694- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1695 278.
1696
Brett Cannonc3647ac2005-04-26 03:45:26 +00001697- patch #1109424: int, long, float, complex, and unicode now check for the
1698 proper magic slot for type conversions when subclassed. Previously the
1699 magic slot was ignored during conversion. Semantics now match the way
1700 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001701 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001702 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001703 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001704
Barry Warsawc8d907c2005-04-19 23:43:40 +00001705- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1706 NULL, now raise an AttributeError when attempting to set or delete the
1707 attribute. Previously a TypeError was raised, but this was inconsistent
1708 with the equivalent pure-Python implementation.
1709
Michael W. Hudson774479c2005-04-18 08:46:17 +00001710- It is now safe to call PyGILState_Release() before
1711 PyEval_InitThreads() (note that if there is reason to believe there
1712 are multiple threads around you still must call PyEval_InitThreads()
1713 before using the Python API; this fix is for extension modules that
1714 have no way of knowing if Python is multi-threaded yet).
1715
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001716- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1717 disabled caused a crash.
1718
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001719- Bug #1165306: instancemethod_new allowed the creation of a method
1720 with im_class == im_self == NULL, which caused a crash when called.
1721
Tim Petersecc6e6a2005-07-10 22:30:55 +00001722- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001723 fixes the crash seen in bug #1165761
1724
Raymond Hettinger96229b12005-03-11 06:49:40 +00001725- Added two new builtins, any() and all().
1726
Brett Cannon409d8f22005-03-05 06:47:57 +00001727- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001728 (e.g., ``class C(): pass`` is no longer a syntax error).
1729 Patch #1176012 added support to the 'parser' module and 'compiler' package
1730 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001731
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001732- Patch #1115086: Support PY_LONGLONG in structmember.
1733
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001734- Bug #1155938: new style classes did not check that __init__() was
1735 returning None.
1736
Tim Petersecc6e6a2005-07-10 22:30:55 +00001737- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001738 ('\') with a specific error message.
1739
Martin v. Löwisff232d72005-03-03 09:24:38 +00001740- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1741
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001742- Bug #1124295: the __name__ attribute of file objects was
1743 inadvertently made inaccessible in restricted mode.
1744
Tim Petersecc6e6a2005-07-10 22:30:55 +00001745- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001746 an ferror() call.
1747
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001748- min() and max() now support key= arguments with the same meaning as in
1749 list.sort().
1750
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001751- The peephole optimizer now performs simple constant folding in expressions:
1752 (2+3) --> (5).
1753
Raymond Hettingera422c342005-01-11 03:03:27 +00001754- set and frozenset objects can now be marshalled. SF #1098985.
1755
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001756- Bug #1077106: Poor argument checking could cause memory corruption
1757 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001758
Jeremy Hyltonab630502005-02-04 18:44:06 +00001759- The parser did not complain about future statements in illegal
1760 positions. It once again reports a syntax error if a future
1761 statement occurs after anything other than a doc string.
1762
Neil Schemenauercf52c072005-08-12 17:34:58 +00001763- Change the %s format specifier for str objects so that it returns a
1764 unicode instance if the argument is not an instance of basestring and
1765 calling __str__ on the argument returns a unicode instance.
1766
Tim Petersf4e69282006-02-27 17:15:31 +00001767- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1768 current thread state when the auto-GIL-state machinery knows about
1769 it (since the thread state is being deleted, continuing to remember it
1770 can't help, but can hurt if another thread happens to get created with
1771 the same thread id).
1772
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001773Extension Modules
1774-----------------
1775
Georg Brandl43f08a82006-03-31 18:01:16 +00001776- Patch #1380952: fix SSL objects timing out on consecutive read()s
1777
Neal Norwitz05a45592006-03-20 06:30:08 +00001778- Patch #1309579: wait3 and wait4 were added to the posix module.
1779

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001963- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1964 been renamed to have only a single underscore prefix. This was done to
1965 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001966
Nick Coghlan43832302006-04-23 17:04:07 +00001967- PEP 338: new module runpy defines a run_module function to support
1968 executing modules which provide access to source code or a code object
1969 via the PEP 302 import mechanisms.
1970
Anthony Baxter93f5b932006-04-03 08:05:07 +00001971- The email module's parsedate_tz function now sets the daylight savings

1979 in attribute values.
1980
Anthony Baxterc51ee692006-04-01 00:57:31 +00001981- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001982 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001983 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001984 module will not be built.
1985
Tim Petersc17976e2006-04-01 00:26:53 +00001986- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1987 aren't officially supported here, and trying to use them will probably
1988 raise an exception some day. But dicts have been allowed, and "mostly
1989 worked", so support for them won't go away without warning.
1990
Georg Brandl338ef7d2006-03-31 18:42:16 +00001991- Bug #1445068: getpass.getpass() can now be given an explicit stream

2009
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002010- email 4.0 package now integrated. This is largely the same as the email 3.0
2011 package that was included in Python 2.3, except that PEP 8 module names are
2012 now used (e.g. mail.message instead of email.Message). The MIME classes
2013 have been moved to a subpackage (e.g. email.mime.text instead of
2014 email.MIMEText). The old names are still supported for now. Several
2015 deprecated Message methods have been removed and lots of bugs have been
2016 fixed. More details can be found in the email package documentation.
2017
Walter Dörwald40108c92006-03-27 08:15:44 +00002018- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2019 (a subclass of tuple) that provides incremental decoders and encoders
2020 (a way to use stateful codecs without the stream API). Python functions
2021 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2022 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2023 have been added.

2026 a ValueError instead of a StopIteration now (like file and cString.String do).

2106
2107 "The consensus of researchers in this area (at least as
2108 expressed at the NIST Hash Function Workshop 10/31/05),
2109 is that SHA-256 is a good choice for the time being, but
2110 that research should continue, and other alternatives may
2111 arise from this research. The larger SHA's also seem OK."

2300 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002301 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002302 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002303 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2304 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002305 + reader now allows \r characters to be quoted (previously it only allowed
2306 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002307 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002308 + Dialect classes passed to the module are no longer instantiated by
2309 the module before being parsed (the former validation scheme required
2310 this, but the mechanism was unreliable).
2311 + The dialect registry now contains instances of the internal
2312 C-coded dialect type, rather than references to python objects.
2313 + the internal c-coded dialect type is now immutable.
2314 + register_dialect now accepts the same keyword dialect specifications
2315 as the reader and writer, allowing the user to register dialects
2316 without first creating a dialect class.
2317 + a configurable limit to the size of parsed fields has been added -
2318 previously, an unmatched quote character could result in the entire
2319 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002320 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002321 the parser field size limit (returning the former limit). The initial
2322 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002323 + A line_num attribute has been added to the reader object, which tracks
2324 the number of lines read from the source iterator. This is not
2325 the same as the number of records returned, as records can span
2326 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002327 + reader and writer objects were not being registered with the cyclic-GC.
2328 This has been fixed.
2329
Brett Cannone6539c42005-01-08 02:43:53 +00002330- _DummyThread objects in the threading module now delete self.__block that is
2331 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2332 lock primitives tend to be limited in number and thus should not be wasted on
2333 a _DummyThread object. Fixes bug #1089632.
2334
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002335- The imghdr module now detects Exif files.
2336
Raymond Hettinger6065d322004-12-20 23:51:53 +00002337- StringIO.truncate() now correctly adjusts the size attribute.
2338 (Bug #951915).
2339
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002340- locale.py now uses an updated locale alias table (built using
2341 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2342 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002343 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002344
Raymond Hettinger3557f422004-12-07 12:02:02 +00002345- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2346
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002347- the pickle module no longer accepts the deprecated None option in the
2348 args tuple returned by __reduce__().
2349
Brett Cannon84667c02004-12-07 03:25:18 +00002350- optparse now optionally imports gettext. This allows its use in setup.py.
2351
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002352- the pickle module no longer uses the deprecated bin parameter.
2353
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002354- the shelve module no longer uses the deprecated binary parameter.
2355

2357
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002358- the filecmp module no longer uses the deprecated use_statcache argument.
2359
Raymond Hettinger664347b2004-12-04 21:21:53 +00002360- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2361 extended or overridden by subclasses. Formerly, the subclassed method would
2362 be ignored by the rest of the module. (Bug #1078905).
2363
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002364- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002365 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002366
Walter Dörwald36733692004-12-22 12:50:50 +00002367- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2368 once when a size argument is given. This prevents a buffer overflow in the
2369 tokenizer with very long source lines.
2370
Barry Warsaw538561e2006-01-01 21:48:54 +00002371- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2372 immediately after creating the object, without any intervening
2373 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002374
Skip Montanaro05885812005-01-16 20:48:27 +00002375- The reconvert.quote function can now emit triple-quoted strings. The
2376 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002377
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002378- ``UserString.MutableString`` now supports negative indices in
2379 ``__setitem__`` and ``__delitem__``
2380
Greg Ward40407942005-03-05 02:53:17 +00002381- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2382 correctly.
2383
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002384- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2385 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2386 character even if the user has passed a size parameter to get a proper
2387 line ending. Remove the special handling of a "\r\n" that has been split
2388 between two lines.
2389
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002390- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2391 about illegal code points. The codec now supports PEP 293 style error
2392 handlers.
2393
Walter Dörwald78a78b02005-09-01 12:04:29 +00002394- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002395 from the input stream, so that the output is a byte string in the correct
2396 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002397
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002398- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2399 considering it exactly like a '*'.
2400
Walter Dörwald007f8df2005-10-09 19:42:27 +00002401- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2402 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002403
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002404- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2405
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002406- Patch #1413711: Certain patterns of differences were making difflib
2407 touch the recursion limit.
2408
Walter Dörwald58917a62006-03-31 15:26:22 +00002409- Bug #947906: An object oriented interface has been added to the calendar
2410 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002411 called as a script (e.g. via ``python -mcalendar``). Localized month and
2412 weekday names can be ouput (even if an exotic encoding is used) using
2413 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002414
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002415Build
2416-----
2417
Neal Norwitz602d3392006-03-31 08:21:40 +00002418- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2419 by using -mieee gcc option.
2420
Martin v. Löwis86d66262006-02-17 08:40:11 +00002421- Patch #1432345: Make python compile on DragonFly.
2422
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002423- Build support for Win64-AMD64 was added.
2424
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002425- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2426
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002427- Patch #881820: look for openpty and forkpty also in libbsd.
2428
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002429- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2430 The zlib module is now builtin on Windows.
2431
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002432- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2433
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002434- Bug #1189330: configure did not correctly determine the necessary
2435 value of LINKCC if python was built with GCC 4.0.
2436
Trent Mick8321b422005-07-26 02:29:21 +00002437- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2438 vulnerability in zlib 1.2.1 and 1.2.2.
2439
Brett Cannon08cd5982005-04-24 22:26:38 +00002440- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2441 flags that change binary compatibility. Changes were also made to
2442 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002443 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002444
Bob Ippolitoed233462005-03-29 13:47:59 +00002445- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2446 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2447 no longer exists). This configure patch makes things right.
2448
Martin v. Löwise2713be2005-03-08 15:03:08 +00002449- Bug #1158607: Build with --disable-unicode again.
2450
Brett Cannon46d96232005-02-16 00:07:19 +00002451- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2452 defined. Discovered as a result of not being able to build on OS X.
2453
Brett Cannon516592f2004-12-07 00:42:59 +00002454- setup.py now uses the directories specified in LDFLAGS using the -L option
2455 and in CPPFLAGS using the -I option for adding library and include
2456 directories, respectively, for compiling extension modules against. This has
2457 led to the core being compiled using the values in CPPFLAGS. It also removes
2458 the need for the special-casing of both DarwinPorts and Fink for darwin since
2459 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2460 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2461 Fink, ``-I/opt/local/include`` for DarwinPorts).
2462
Brett Cannon43802422005-02-10 20:48:03 +00002463- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2464 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2465 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2466 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002468C API
2469-----
2470
Tim Petersc9d78aa2006-03-26 23:27:58 +00002471- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2472 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2473 is obtained via the ``PyObject_`` family, it must be released via the
2474 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2475 always been officially true, but when Python's small-object allocator was
2476 introduced, an attempt was made to cater to a few extension modules
2477 discovered at the time that obtained memory via ``PyObject_New`` but
2478 released it via ``PyMem_DEL``. It's years later, and if such code still
2479 exists it will fail now (probably with segfaults, but calling wrong
2480 low-level memory management functions can yield many symptoms).
2481
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002482- Added a C API for set and frozenset objects.
2483
Raymond Hettinger66517482004-12-03 11:45:13 +00002484- Removed PyRange_New().
2485
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002486- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2487 mapping argument now. This string is used as a mapping table. Byte values
2488 greater than the length of the string and 0xFFFE are treated as undefined
2489 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002496
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002497- Patch #1276356: New resource "urlfetch" is implemented. This enables
