Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000370- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
371 mode by only placing a timeout on the select() if an input hook has
372 been defined. This prevents an interactive Python from waking up 10

383 variables.
384
Brett Cannon6d9520c2006-12-13 23:09:53 +0000385- Added guard_warnings_filter to test.test_support. It returns a context
386 manager that protects the 'warnings' module's filter from being mutated
387 once the context has been exited.
388
Thomas Heller112d1a62006-10-27 19:05:53 +0000389- Added some tests for modulefinder.

488Core and builtins
489-----------------
490
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000491- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000492 compared equal or unequal to a string and a UnicodeDecodeError
493 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000494
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000495 Instead, the equal (==) and unequal (!=) comparison operators will
496 now issue a UnicodeWarning and interpret the two objects as
497 unequal. The UnicodeWarning can be filtered as desired using
498 the warning framework, e.g. silenced completely, turned into an
499 exception, logged, etc.
500
501 Note that compare operators other than equal and unequal will still
502 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000503
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000504- Fix segfault when doing string formatting on subclasses of long.
505
506- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
507 with new-style classes.
508
509- Fix bug related to __len__ functions returning negative values with
510 classic classes.
511
512- Patch #1538606, Fix __index__() clipping. There were some problems
513 discovered with the API and how integers that didn't fit into Py_ssize_t
514 were handled. This patch attempts to provide enough alternatives
515 to effectively use __index__.
516
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000517- Bug #1536021: __hash__ may now return long int; the final hash
518 value is obtained by invoking hash on the long int.
519
Thomas Hellerab1049c2006-08-08 17:37:00 +0000520- Bug #1536786: buffer comparison could emit a RuntimeWarning.
521
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000522- Bug #1535165: fixed a segfault in input() and raw_input() when
523 sys.stdin is closed.
524
Thomas Heller74d36f02006-08-04 18:17:40 +0000525- On Windows, the PyErr_Warn function is now exported from
526 the Python dll again.
527
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000528- Bug #1191458: tracing over for loops now produces a line event
529 on each iteration. Fixing this problem required changing the .pyc
530 magic number. This means that .pyc files generated before 2.5c1
531 will be regenerated.
532
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000533- Bug #1333982: string/number constants were inappropriately stored
534 in the byte code and co_consts even if they were not used, ie
535 immediately popped off the stack.
536
Georg Brandle9462c72006-08-04 18:03:37 +0000537- Fixed a reference-counting problem in property().

540Library
541-------
542
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000543- Fix a bug in the ``compiler`` package that caused invalid code to be
544 generated for generator expressions.
545
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000546- The distutils version has been changed to 2.5.0. The change to
547 keep it programmatically in sync with the Python version running
548 the code (introduced in 2.5b3) has been reverted. It will continue
549 to be maintained manually as static string literal.
550
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000551- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000552 and this cannot be converted to the required C type, an exception is
553 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000554 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000555
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000556- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000557 an exception.
558
Tim Petersc10c9d02006-09-05 02:18:09 +0000559- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000560 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000561 workarounds for clocks with low resolution, to stop the code yielding
562 duplicate UUIDs.
563
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000564- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
565 before raising SystemExit, allowing IDLE to honor quit() and exit().
566
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000567- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
568
Georg Brandl7a1af772006-08-14 21:55:28 +0000569- Patch #1536071: trace.py should now find the full module name of a
570 file correctly even on Windows.
571
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000572- logging's atexit hook now runs even if the rest of the module has
573 already been cleaned up.
574
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000575- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000576
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000577- Bug #1531405, format_exception no longer raises an exception if
578 str(exception) raised an exception.
579
Neil Schemenauer06ded092006-08-04 16:20:30 +0000580- Fix a bug in the ``compiler`` package that caused invalid code to be
581 generated for nested functions.

Fred Drake53912162006-07-29 13:22:49 +0000646What's New in Python 2.5 beta 3?
647================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000648
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000649*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000650
651Core and builtins
652-----------------
653
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000654- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000655 returned a long (see PEP 353).
656
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000657- Bug #1515471: string.replace() accepts character buffers again.
658
Neal Norwitz07aadb12006-07-30 06:55:48 +0000659- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
660 This provides the proper warning for struct.pack().
661 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
662
Neal Norwitz0d62a062006-07-30 06:53:31 +0000663- Patch #1531113: Fix augmented assignment with yield expressions.
664 Also fix a SystemError when trying to assign to yield expressions.
665
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000666- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
667 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
668 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
669 excessive filesystem operations during imports.
670
Tim Petersbc24eee2006-07-27 01:14:53 +0000671- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
672 operations on signed longs that are formally undefined by C.
673 Unfortunately, at least one compiler now cares about that, so complicated
674 the code to make that compiler happy again.
675
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000676- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
677
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000678- Patch #1232023: Stop including current directory in search
679 path on Windows.
680
Neal Norwitze1fdb322006-07-21 05:32:28 +0000681- Fix some potential crashes found with failmalloc.
682
Neal Norwitze7563102006-07-17 01:00:16 +0000683- Fix warnings reported by Klocwork's static analysis tool.
684
Neal Norwitz84be93b2006-07-16 01:50:38 +0000685- Bug #1512814, Fix incorrect lineno's when code within a function
686 had more than 255 blank lines.
687
Georg Brandl9dceedb2006-07-12 15:31:17 +0000688- Patch #1521179: Python now accepts the standard options ``--help`` and
689 ``--version`` as well as ``/?`` on Windows.
690
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000691- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000692 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000693 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000694
Tim Peters112aad32006-07-19 00:03:19 +0000695- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000696 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000697 new ``sys._current_frames()`` returns a dictionary with one entry,
698 mapping the faux "thread id" 0 to the current frame.
699
Ronald Oussoren3075e162006-07-25 20:28:55 +0000700- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000701
Ronald Oussoren3075e162006-07-25 20:28:55 +0000702
Neal Norwitza1f10902006-07-12 07:28:29 +0000703Library
704-------
705
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000706- Correction of patch #1455898: In the mbcs decoder, set final=False
707 for stream decoder, but final=True for the decode function.
708
Georg Brandl07fec3a2006-08-01 18:49:24 +0000709- os.urandom no longer masks unrelated exceptions like SystemExit or
710 KeyboardInterrupt.
711
Tim Peters4643c2f2006-08-10 22:45:34 +0000712- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000713 shutil.copytree on Windows
714
Georg Brandle34ac7c2006-07-30 11:07:23 +0000715- Bug #1002398: The documentation for os.path.sameopenfile now correctly
716 refers to file descriptors, not file objects.
717
Tim Petersc10c9d02006-09-05 02:18:09 +0000718- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000719 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000720 #1513611, and probably others.
721
Georg Brandledd9b0d2006-07-29 09:33:26 +0000722- Bug #1441397: The compiler module now recognizes module and function
723 docstrings correctly as it did in Python 2.4.
724
Tim Peters6f681472006-07-27 23:44:37 +0000725- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
726 lost that tests are sorted by name before being run. This rarely
727 matters for well-written tests, but can create baffling symptoms if
728 side effects from one test to the next affect outcomes. ``DocTestFinder``
729 has been changed to sort the list of tests it returns.
730
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000731- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000732 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000733
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000734- Bug #978833: Really close underlying socket in _socketobject.close.
735
Georg Brandl8c036cc2006-08-20 13:15:39 +0000736- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
737 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000738
Georg Brandlcf0c1722006-07-26 07:23:32 +0000739- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
740 to recursive calls and call it with the failing package name.
741
Martin v. Löwis0b483032006-07-25 09:53:12 +0000742- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
743
Georg Brandlc13c34c2006-07-24 14:09:56 +0000744- Patch #1515343: Fix printing of deprecated string exceptions with a
745 value in the traceback module.
746
Greg Ward48fae7a2006-07-23 16:05:51 +0000747- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
748
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000749- Patch #1524429: Use repr() instead of backticks in Tkinter again.
750
Brett Cannoncaebe222006-07-18 04:41:36 +0000751- Bug #1520914: Change time.strftime() to accept a zero for any position in its
752 argument tuple. For arguments where zero is illegal, the value is forced to
753 the minimum value that is correct. This is to support an undocumented but
754 common way people used to fill in inconsequential information in the time
755 tuple pre-2.4.
756
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000757- Patch #1220874: Update the binhex module for Mach-O.
758
Barry Warsawb110bad2006-07-21 14:51:07 +0000759- The email package has improved RFC 2231 support, specifically for
760 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
761 (name*0=<blah>) parameter continuations. This may change the types of
762 values returned from email.message.Message.get_param() and friends.
763 Specifically in some cases where non-encoded continuations were used,
764 get_param() used to return a 3-tuple of (None, None, string) whereas now it
765 will just return the string (since non-encoded continuations don't have
766 charset and language parts).
767
768 Also, whereas % values were decoded in all parameter continuations, they are
769 now only decoded in encoded parameter parts.
770
Ronald Oussoren3075e162006-07-25 20:28:55 +0000771- Bug #1517990: IDLE keybindings on MacOS X now work correctly
772
773- Bug #1517996: IDLE now longer shows the default Tk menu when a
774 path browser, class browser or debugger is the frontmost window on MacOS X
775
Barry Warsaw00decd72006-07-27 23:43:15 +0000776- Patch #1520294: Support for getset and member descriptors in types.py,
777 inspect.py, and pydoc.py. Specifically, this allows for querying the type
778 of an object against these built-in types and more importantly, for getting
779 their docstrings printed in the interactive interpreter's help() function.
780
Ronald Oussoren3075e162006-07-25 20:28:55 +0000781
Neal Norwitza1f10902006-07-12 07:28:29 +0000782Extension Modules
783-----------------
784
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000785- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
786 a socket operation on a socket with a timeout, the exception will be
787 caught correctly. Previously, the exception was not caught.
788
Thomas Heller1393d6a2006-07-28 21:43:20 +0000789- Patch #1529514: The _ctypes extension is now compiled on more
790 openbsd target platforms.
791
Tim Peters9cab5932006-07-28 00:30:00 +0000792- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
793 a memory leak, affecting pickles and deep copies.
794
Tim Petersbc24eee2006-07-27 01:14:53 +0000795- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000796 Paul Eggert.
797
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000798- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
799
Thomas Hellerce049a02006-07-14 17:51:14 +0000800- Patch #1521817: Index range checking on ctypes arrays containing
801 exactly one element enabled again. This allows iterating over these
802 arrays, without the need to check the array size before.
803
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000804- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000805 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000806 /dev/null in certain cases; this is now fixed.
807
Thomas Heller47d7a062006-07-12 08:43:47 +0000808- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
809 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000810
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000811- Because of a misspelled preprocessor symbol, ctypes was always
812 compiled without thread support; this is now fixed.
813
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000814- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
815 methods now allow their database parameter to be None as the
816 sleepycat API allows.
817
Matt Flemingec926502006-07-28 11:27:27 +0000818- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
819 bluetooth API compared with Linux and FreeBSD.
820
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000821Tests
822-----
823
824- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
825 how long the test file should take to play. Now accepts taking 2.93 secs
826 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
827
Georg Brandl4793aa32006-07-28 18:31:39 +0000828- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
829 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
830 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000831
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000832Build
833-----
834
835- Bug #1439538: Drop usage of test -e in configure as it is not portable.
836
Ronald Oussoren26cad082006-08-01 21:00:57 +0000837Mac
838---
839
840- PythonLauncher now works correctly when the path to the script contains
841 characters that are treated specially by the shell (such as quotes).
842
843- Bug #1527397: PythonLauncher now launches scripts with the working directory
844 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000845 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000846 expect.

854Core and builtins
855-----------------
856
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000857- Bug #1441486: The literal representation of -(sys.maxint - 1)
858 again evaluates to a int object, not a long.
859
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000860- Bug #1501934: The scope of global variables that are locally assigned
861 using augmented assignment is now correctly determined.
862
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000863- Bug #927248: Recursive method-wrapper objects can now safely
864 be released.
865
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000866- Bug #1417699: Reject locale-specific decimal point in float()
867 and atof().
868
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000869- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
870 omit a default "error" argument for NULL pointer. This allows
871 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000872
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000873- Bug #1519018: 'as' is now validated properly in import statements.
874
Neal Norwitz28746ab2006-07-09 22:14:42 +0000875- On 64 bit systems, int literals that use less than 64 bits are
876 now ints rather than longs.
877
Neal Norwitzed657552006-07-10 00:04:44 +0000878- Bug #1512814, Fix incorrect lineno's when code at module scope
879 started after line 256.
880
Tim Peters32a83612006-07-10 21:08:24 +0000881- New function ``sys._current_frames()`` returns a dict mapping thread
882 id to topmost thread stack frame. This is for expert use, and is
883 especially useful for debugging application deadlocks. The functionality
884 was previously available in Fazal Majid's ``threadframe`` extension
885 module, but it wasn't possible to do this in a wholly threadsafe way from
886 an extension.

889-------
890
Martin v. Löwis77621582006-07-30 13:27:31 +0000891- Bug #1257728: Mention Cygwin in distutils error message about a missing
892 VS 2003.
893

895
Tim Peters32a83612006-07-10 21:08:24 +0000896- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000897 environment variable to be set in order to the SDK environment
898 for finding the compiler, include files, etc.
899
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000900- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000902- warnings.py now ignores ImportWarning by default
903
Thomas Woutersadd19112006-07-05 11:03:49 +0000904- string.Template() now correctly handles tuple-values. Previously,
905 multi-value tuples would raise an exception and single-value tuples would
906 be treated as the value they contain, instead.
907
Martin v. Löwisede77f52006-07-03 13:01:35 +0000908- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

921 is created.
922
Martin v. Löwis7596e832006-07-01 15:33:37 +0000923- Bug #1513223: .close() of a _socketobj now releases the underlying
924 socket again, which then gets closed as it becomes unreferenced.
925

933
Brett Cannon53ab5b72006-06-22 16:49:14 +0000934- Bug #1510580: The 'warnings' module improperly required that a Warning
935 category be either a types.ClassType and a subclass of Warning. The proper
936 check is just that it is a subclass with Warning as the documentation states.
937
Georg Brandlad29e632006-06-21 17:45:17 +0000938- The compiler module now correctly compiles the new try-except-finally
939 statement (bug #1509132).
940

945
Gerhard Häring762fbd32006-07-02 17:48:30 +0000946- The sqlite3 module did cut off data from the SQLite database at the first

948 now.
949

951-----------------
952
Tim Peters112aad32006-07-19 00:03:19 +0000953- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
954 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
955 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000956
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000957- Assigning None to pointer type fields in ctypes structures possible
958 overwrote the wrong fields, this is fixed now.
959
960- Fixed a segfault in _ctypes when ctypes.wintypes were imported
961 on non-Windows platforms.
962
963- Bug #1518190: The ctypes.c_void_p constructor now accepts any
964 integer or long, without range checking.
965
966- Patch #1517790: It is now possible to use custom objects in the ctypes
967 foreign function argtypes sequence as long as they provide a from_param
968 method, no longer is it required that the object is a ctypes type.
969
970- The '_ctypes' extension module now works when Python is configured
971 with the --without-threads option.
972
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000973- Bug #1513646: os.access on Windows now correctly determines write

988
Tim Peters32a83612006-07-10 21:08:24 +0000989- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000990 Previously, the slight difference could cause compilation errors of the
991 'zlib' module on systems with more than one version of zlib.
992
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000993- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001023
1024Core and builtins
1025-----------------
1026
Georg Brandla56b9152006-06-19 06:35:54 +00001027- Patch #1507676: Error messages returned by invalid abstract object operations
1028 (such as iterating over an integer) have been improved and now include the
1029 type of the offending object to help with debugging.
1030
Brett Cannonea3912b2006-06-13 21:46:41 +00001031- Bug #992017: A classic class that defined a __coerce__() method that returned
1032 its arguments swapped would infinitely recurse and segfault the interpreter.
1033
Neal Norwitz909eb122006-06-12 02:13:21 +00001034- Fix the socket tests so they can be run concurrently.
1035
Neal Norwitzb9845e72006-06-12 02:11:18 +00001036- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001037 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001038
Brett Cannon22565aa2006-06-09 22:31:23 +00001039- Bug #532646: object.__call__() will continue looking for the __call__
1040 attribute on objects until one without one is found. This leads to recursion
1041 when you take a class and set its __call__ attribute to an instance of the
1042 class. Originally fixed for classic classes, but this fix is for new-style.
1043 Removes the infinite_rec_3 crasher.
1044
Georg Brandl24250812006-06-09 18:45:48 +00001045- The string and unicode methods startswith() and endswith() now accept
1046 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1047
Brett Cannonde3b0522006-06-08 17:00:45 +00001048- Buffer objects, at the C level, never used the char buffer
1049 implementation even when the char buffer for the wrapped object was
1050 explicitly requested (originally returned the read or write buffer).
1051 Now a TypeError is raised if the char buffer is not present but is
1052 requested.
1053
Georg Brandlddbaa662006-06-04 21:56:52 +00001054- Patch #1346214: Statements like "if 0: suite" are now again optimized
1055 away like they were in Python 2.4.
1056
Georg Brandlb7c8f542006-05-27 12:30:25 +00001057- Builtin exceptions are now full-blown new-style classes instead of
1058 instances pretending to be classes, which speeds up exception handling
1059 by about 80% in comparison to 2.5a2.
1060
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001061- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1062 Unicode 4.1.
1063
Georg Brandlf4ef1162006-05-26 18:03:31 +00001064- Patch #921466: sys.path_importer_cache is now used to cache valid and
1065 invalid file paths for the built-in import machinery which leads to
1066 fewer open calls on startup.
1067
Tim Peters696cf432006-05-24 21:10:40 +00001068- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1069 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1070 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1071 the number of input digits (it was and remains linear-time for bases
1072 2, 4, 8, 16 and 32).
1073
Tim Petersb713ec22006-05-23 18:45:30 +00001074- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1075 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1076 an integer close to ``sys.maxint``. This was repaired by patch
1077 #1335972, which also gives a nice speedup.
1078
Richard Jonescebbefc2006-05-23 18:28:17 +00001079- Patch #1337051: reduced size of frame objects.
1080
1081- PyErr_NewException now accepts a tuple of base classes as its
1082 "base" parameter.
1083
Richard Jones7c88dcc2006-05-23 10:37:38 +00001084- Patch #876206: function call speedup by retaining allocated frame
1085 objects.
1086
Georg Brandl7b90e162006-05-18 07:01:27 +00001087- Bug #1462152: file() now checks more thoroughly for invalid mode
1088 strings and removes a possible "U" before passing the mode to the
1089 C library function.
1090
Neal Norwitz1004a532006-05-15 07:17:23 +00001091- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1092
Neal Norwitz373f0a72006-05-15 07:04:36 +00001093- Bug #1487966: Fix SystemError with conditional expression in assignment
1094
Martin v. Löwis879768d2006-05-11 13:28:43 +00001095- WindowsError now has two error code attributes: errno, which carries
1096 the error values from errno.h, and winerror, which carries the error
1097 values from winerror.h. Previous versions put the winerror.h values
1098 (from GetLastError()) into the errno attribute.
1099
Martin v. Löwis77736712006-05-04 05:51:03 +00001100- Patch #1475845: Raise IndentationError for unexpected indent.
1101
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001102- Patch #1479181: split open() and file() from being aliases for each other.
1103
Tim Peters44bd9862006-06-01 13:49:23 +00001104- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1105 methods were always silently ignored by dictionaries when comparing keys.
1106 They are now passed through (except when using the C API function
1107 ``PyDict_GetItem()``, whose semantics did not change).
1108
1109- Bug #1456209: In some obscure cases it was possible for a class with a
1110 custom ``__eq__()`` method to confuse dict internals when class instances
1111 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1112 No, you don't have any code that did this ;-)

1125
Nick Coghlanc649ec52006-05-29 12:43:05 +00001126- Patch #1478788 (modified version): The functional extension module has
1127 been renamed to _functools and a functools Python wrapper module added.
1128 This provides a home for additional function related utilities that are
1129 not specifically about functional programming. See PEP 309.
1130
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001131- Patch #1493701: performance enhancements for struct module.

1139 enabled builds on Windows and systems with Posix threads support.
1140
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001141- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1142 (up to the system limit of 32K characters).
1143
1144- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1145 As a result, these functions now raise WindowsError instead of OSError.
1146
Tim Peters7a822da2006-05-25 21:50:17 +00001147- ``time.clock()`` on Win64 should use the high-performance Windows
1148 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1149 Windows platforms).
1150
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001151- Calling Tk_Init twice is refused if the first call failed as that
1152 may deadlock.
1153
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001154- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1155 accept it without potentially using an uninitialized pointer.
1156
1157- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1158 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1168 results. It could previously incorrectly return 0 in some cases.
1169 Fixes SF bug 1493322 (pybsddb bug 1184012).
1170
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001171- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1173 Fixes SF python patch/bug #1408584.
1174
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001175- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001176 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001177 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1178 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl2605ca82006-06-14 06:08:31 +00001204- Bug #1339007: Shelf objects now don't raise an exception in their
1205 __del__ method when initialization failed.
1206
Martin v. Löwisd8251432006-06-14 05:21:04 +00001207- Patch #1455898: The MBCS codec now supports the incremental mode for
1208 double-byte encodings.
1209
Tim Peters43898b42006-06-14 04:09:25 +00001210- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1211 guarantee that adjacent triples in the return list always describe
1212 non-adjacent blocks. Previously, a pair of matching blocks could end
1213 up being described by multiple adjacent triples that formed a partition
1214 of the matching pair.
1215
Greg Ward0e0c9f42006-06-11 16:24:11 +00001216- Bug #1498146: fix optparse to handle Unicode strings in option help,
1217 description, and epilog.
1218
Greg Wardd1c797e2006-06-11 14:42:41 +00001219- Bug #1366250: minor optparse documentation error.
1220
Greg Ward7f547402006-06-11 00:40:49 +00001221- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1222 clarify docs.
1223
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001224- The wsgiref package has been added to the standard library.
1225
Nick Coghlan676725d2006-06-08 13:54:49 +00001226- The functions update_wrapper() and wraps() have been added to the functools
1227 module. These make it easier to copy relevant metadata from the original
1228 function when writing wrapper functions.
1229
Tim Petersd6a9eef2006-06-05 01:48:21 +00001230- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1231 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001232
Martin v. Löwis3f767792006-06-04 19:36:28 +00001233- Patch #1359618: Speed up charmap encoder by using a trie structure
1234 for lookup.
1235
Tim Petersd609b1a2006-06-02 23:22:51 +00001236- The functions in the ``pprint`` module now sort dictionaries by key
1237 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1238 if and only if its display required more than one line, although that
1239 wasn't documented. The new behavior increases predictability; e.g.,
1240 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1241
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001242- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1243 (thanks for J. J. Lee).
1244
Georg Brandl2b330372006-05-28 20:23:12 +00001245- Patch #1496206: improve urllib2 handling of passwords with respect to
1246 default HTTP and HTTPS ports.
1247
George Yoshidaf3c65de2006-05-28 16:39:09 +00001248- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1249
Bob Ippolito7298f272006-05-23 18:43:47 +00001250- Patch #1281707: speed up gzip.readline.
1251
Georg Brandlb89316f2006-05-17 15:51:16 +00001252- Patch #1180296: Two new functions were added to the locale module:
1253 format_string() to get the effect of "format % items" but locale-aware,
1254 and currency() to format a monetary number with currency sign.
1255
Georg Brandle3a25832006-05-17 14:56:04 +00001256- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1257 and several features added, such as speed and geometry control.
1258
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001259- Patch #1488881: add support for external file objects in bz2 compressed
1260 tarfiles.
1261
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001262- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1263 stdout arguments, making it possible to redirect input and output
1264 for remote debugging.
1265
1266- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1267 a couple of issues, notably handling of long file names using the
1268 GNU LONGNAME extension.
1269
1270- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1271 new flag when ``name`` is already the name of an option flag.
1272
1273- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1274 package.
1275
1276- Patch #1472854: make the rlcompleter.Completer class usable on non-
1277 UNIX platforms.
1278
1279- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1280
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001281- Bug #1472827: correctly escape newlines and tabs in attribute values in
1282 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001312What's New in Python 2.5 alpha 2?
1313=================================
1314
1315*Release date: 27-APR-2006*
1316
1317Core and builtins
1318-----------------
1319
Thomas Heller1b046642006-04-18 18:51:06 +00001320- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1321 by converting these apis from macros into exported functions again:
1322
1323 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1324 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1325 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1326 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1327 PyRun_String Py_CompileString
1328
Martin v. Löwis45294a92006-04-18 06:24:08 +00001329- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1330
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001331- All uses of PyStructSequence_InitType have been changed to initialize
1332 the type objects only once, even if the interpreter is initialized
1333 multiple times.
1334
Neal Norwitz61546162006-04-14 05:20:28 +00001335- Bug #1454485, array.array('u') could crash the interpreter. This was
1336 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1337 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1338
1339- Py_UNICODE is unsigned. It was always documented as unsigned, but
1340 due to a bug had a signed value in previous versions.
1341
Tim Peters3a5e8b12006-04-11 01:44:07 +00001342- Patch #837242: ``id()`` of any Python object always gives a positive
1343 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1344 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001345 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001346 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001347
Tim Peters3a5e8b12006-04-11 01:44:07 +00001348 def __hash__(self):
1349 return id(self) # WRONG
1350
1351 because a hash result must be a (short) Python int but it was always
1352 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001353 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001354 was always usable as a hash value before this patch. That's no longer
1355 necessarily so.
1356
1357- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001358 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001359 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001360 #1454844)
1361
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001362- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1363 involving generators that have paused outside of any ``try`` or ``with``
1364 blocks. (In 2.5a1, a paused generator that was part of a reference
1365 cycle could not be garbage collected, regardless of whether it was
1366 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001367
Anthony Baxter51bcb682006-04-05 14:51:42 +00001368Extension Modules

1370
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001371- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1372 is a macro.
1373
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001374- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1375 fails with an error condition.
1376
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001377- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1378
1379- Bug #1117761: bsddb.*open() no longer raises an exception when using
1380 the cachesize parameter.
1381
1382- Bug #1149413: bsddb.*open() no longer raises an exception when using
1383 a temporary db (file=None) with the 'n' flag to truncate on open.
1384
1385- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1386 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001387
Armin Rigoa9017c32006-04-19 11:50:27 +00001388- Patch #1062014: AF_UNIX sockets under Linux have a special
1389 abstract namespace that is now fully supported.

1392-------
1393
Peter Astrand7d1d4362006-07-14 14:04:45 +00001394- Bug #1223937: subprocess.CalledProcessError reports the exit status
1395 of the process using the returncode attribute, instead of
1396 abusing errno.
1397
Tim Peters711bf302006-04-25 03:31:36 +00001398- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1399 a doctest to be skipped (the code is not run, and the expected output
1400 or exception is ignored).
1401
Nick Coghlanda2268f2006-04-24 04:37:15 +00001402- Fixed contextlib.nested to cope with exceptions being raised and
1403 caught inside exit handlers.
1404
Greg Wardab05edc2006-04-23 03:47:58 +00001405- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1406 hex, octal, or binary; add ``append_const`` action; keep going if
1407 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1408 added ``epilog`` for better help generation).
1409
Tim Peters21fbd572006-04-21 21:18:10 +00001410- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1411 called from a thread spawned as a side effect of importing a module.
1412
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001413- The pydoc module now supports documenting packages contained in
1414 .zip or .egg files.
1415
1416- The pkgutil module now has several new utility functions, such
1417 as ``walk_packages()`` to support working with packages that are either
1418 in the filesystem or zip files.
1419
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001420- The mailbox module can now modify and delete messages from
1421 mailboxes, in addition to simply reading them. Thanks to Gregory
1422 K. Johnson for writing the code, and to the 2005 Google Summer of
1423 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001424
Tim Petersc7605f22006-04-17 21:12:33 +00001425- The ``__del__`` method of class ``local`` in module ``_threading_local``
1426 returned before accomplishing any of its intended cleanup.
1427
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001428- Patch #790710: Add breakpoint command lists in pdb.
1429
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001430- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1433
Anthony Baxtere29002c2006-04-12 12:07:31 +00001434- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1435 Windows. Bug #1469163.
1436
Phillip J. Eby47032112006-04-11 01:07:43 +00001437- The warnings, linecache, inspect, traceback, site, and doctest modules
1438 were updated to work correctly with modules imported from zipfiles or
1439 via other PEP 302 __loader__ objects.
1440
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001441- Patch #1467770: Reduce usage of subprocess._active to processes which
1442 the application hasn't waited on.

1452-----
1453
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001454- The Makefile now has a reindent target, which runs reindent.py on
1455 the library.
1456
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001457- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001461- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1462 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001463 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001464 CXX from --with-cxx-main, see description in README.
1465
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001466- Patch #1429775: Link extension modules with the shared libpython.
1467
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001468- Fixed a libffi build problem on MIPS systems.
1469
Tim Peters8931ff12006-05-13 23:28:20 +00001470- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1471 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1472 and "%zu" for unsigned integers of type ``size_t``.
1473
Anthony Baxter51bcb682006-04-05 14:51:42 +00001474Tests
1475-----
1476
Nick Coghlanda2268f2006-04-24 04:37:15 +00001477- test_contextlib now checks contextlib.nested can cope with exceptions
1478 being raised and caught inside exit handlers.
1479
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001480- test_cmd_line now checks operation of the -m and -c command switches
1481
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001482- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1483 it separately and by hand. It also wasn't cleaning up its changes to
1484 the current Decimal context.
1485
Thomas Woutersabd08882006-04-26 15:53:30 +00001486- regrtest.py now has a -M option to run tests that test the new limits of
1487 containers, on 64-bit architectures. Running these tests is only sensible
1488 on 64-bit machines with more than two gigabytes of memory. The argument
1489 passed is the maximum amount of memory for the tests to use.

1516-----------------
1517
Nick Coghlan43832302006-04-23 17:04:07 +00001518- PEP 338: -m command line switch now delegates to runpy.run_module
1519 allowing it to support modules in packages and zipfiles
1520
Martin v. Löwisc661b882006-04-20 04:54:23 +00001521- On Windows, .DLL is not an accepted file name extension for
1522 extension modules anymore; extensions are only found if they
1523 end in .PYD.
1524
Martin v. Löwisea62d252006-04-03 10:56:49 +00001525- Bug #1421664: sys.stderr.encoding is now set to the same value as
1526 sys.stdout.encoding.
1527
Neal Norwitz92e212f2006-04-03 04:48:37 +00001528- __import__ accepts keyword arguments.
1529
Georg Brandlccadf842006-03-31 18:54:53 +00001530- Patch #1460496: round() now accepts keyword arguments.
1531
Anthony Baxter262c00a2006-03-30 10:53:17 +00001532- Fixed bug #1459029 - unicode reprs were double-escaped.
1533
Hye-Shik Changd478f342006-03-23 12:32:36 +00001534- Patch #1396919: The system scope threads are reenabled on FreeBSD
1535 5.4 and later versions.
1536
Neal Norwitze98ccf62006-03-23 05:39:47 +00001537- Bug #1115379: Compiling a Unicode string with an encoding declaration
1538 now gives a SyntaxError.
1539
Georg Brandlabd1ff82006-03-18 07:59:59 +00001540- Previously, Python code had no easy way to access the contents of a
1541 cell object. Now, a ``cell_contents`` attribute has been added
1542 (closes patch #1170323).
1543
Tim Peterscf79aac2006-03-16 01:14:46 +00001544- Patch #1123430: Python's small-object allocator now returns an arena to
1545 the system ``free()`` when all memory within an arena becomes unused
1546 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1547 freed. Some applications will see a drop in virtual memory size now,
1548 especially long-running applications that, from time to time, temporarily
1549 use a large number of small objects. Note that when Python returns an
1550 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001551 platform C library will in turn return that memory to the operating system.
1552 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001553 appears to be effective at least on Microsoft C and gcc-based systems.
1554 Thanks to Evan Jones for hard work and patience.
1555
Georg Brandl533ff6f2006-03-08 18:09:27 +00001556- Patch #1434038: property() now uses the getter's docstring if there is
1557 no "doc" argument given. This makes it possible to legitimately use
1558 property() as a decorator to produce a read-only property.
1559
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001560- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1561 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1562 of requiring an int or long in slicing and a few other contexts, enabling
1563 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1564
Neal Norwitz995acdf2006-03-07 05:01:00 +00001565- Fixed various bugs reported by Coverity's Prevent tool.
1566
Brett Cannonbf364092006-03-01 04:25:17 +00001567- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1568 new exception base class, BaseException, which has a new message attribute.
1569 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1570 Raising a string exception now raises a DeprecationWarning.
1571
Thomas Woutersfb609f42006-02-28 16:37:25 +00001572- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1573 explicitly relative, using 'from .module import name' to mean 'from the same
1574 package as this module is in. Imports without dots still default to the
1575 old relative-then-absolute, unless 'from __future__ import
1576 absolute_import' is used.
1577
Brett Cannona7446e32006-02-27 23:39:10 +00001578- Properly check if 'warnings' raises an exception (usually when a filter set
1579 to "error" is triggered) when raising a warning for raising string
1580 exceptions.
1581
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001582- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001583 The name was removed from Include/code.h.
1584
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001585- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001586
Guido van Rossum1968ad32006-02-25 22:38:04 +00001587- Patch 1433928:
1588 - The copy module now "copies" function objects (as atomic objects).
1589 - dict.__getitem__ now looks for a __missing__ hook before raising
1590 KeyError.
1591
Tim Peters84ef21c2006-02-28 20:39:06 +00001592- PEP 343: with statement implemented. Needs ``from __future__ import
1593 with_statement``. Use of 'with' as a variable will generate a warning.
1594 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001595 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001596 The following objects have __context__ methods:
1597 - The built-in file type.
1598 - The thread.LockType type.
1599 - The following types defined by the threading module:
1600 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1601 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001602
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001603- Fix the encodings package codec search function to only search
1604 inside its own package. Fixes problem reported in patch #1433198.
1605
1606 Note: Codec packages should implement and register their own
1607 codec search function. PEP 100 has the details.
1608
Tim Peters9ea89d22006-06-04 03:26:02 +00001609- PEP 353: Using ``Py_ssize_t`` as the index type.
1610
1611- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1612 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1613 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1614 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1615 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001616
Neal Norwitzfc76d632006-01-10 06:03:13 +00001617- Patch #1400181, fix unicode string formatting to not use the locale.
1618 This is how string objects work. u'%f' could use , instead of .
1619 for the decimal point. Now both strings and unicode always use periods.
1620
Neal Norwitz671b9e32006-01-09 07:07:12 +00001621- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1622 configure would break checking curses.h.
1623
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001624- Bug #959576: The pwd module is now builtin. This allows Python to be
1625 built on UNIX platforms without $HOME set.
1626
Neal Norwitzc10978f2005-12-19 06:07:16 +00001627- Bug #1072182, fix some potential problems if characters are signed.
1628
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001629- Bug #889500, fix line number on SyntaxWarning for global declarations.
1630
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001631- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1632
Neal Norwitze7214a12005-12-18 05:03:17 +00001633- Support for converting hex strings to floats no longer works.
1634 This was not portable. float('0x3') now raises a ValueError.
1635
Barry Warsaw2a38a862005-12-18 01:27:35 +00001636- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001637 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001638 is now displayed in interactive prompt banner.
1639
Georg Brandlfa166682005-12-17 21:45:17 +00001640- Implementation of PEP 341 - Unification of try/except and try/finally.
1641 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001642 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001643
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001644- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1645 now encodes backslash correctly.
1646
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001647- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1648
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001649- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001650 and long longs.
1651
Neal Norwitz67715f02005-11-09 06:59:35 +00001652- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001653 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001654 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001655
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001656- Replaced most Unicode charmap codecs with new ones using the
1657 new Unicode translate string feature in the builtin charmap
1658 codec; the codecs were created from the mapping tables available
1659 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1660 encodings now include a mapping for the Apple logo)
1661
Tim Peterse3547fd2005-12-16 23:13:57 +00001662- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001663
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001664- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001665
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001666- A new AST parser implementation was completed. The abstract
1667 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001668 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001669
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001670- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001671 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1672
Neal Norwitz708e51a2005-10-03 04:48:15 +00001673- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1674
Neal Norwitz11bd1192005-10-03 00:54:56 +00001675- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1676 Provide a warning when a directory is passed on the command line.
1677
Neal Norwitz40d37812005-10-02 01:48:49 +00001678- Fix segfault with invalid coding.
1679
1680- SF bug #772896: unknown encoding results in MemoryError.
1681
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001682- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001683 supported a __len__() method which evaluated to False when the iterator
1684 was empty.
1685
Guido van Rossum630db602005-09-20 18:49:54 +00001686- On 64-bit platforms, when __len__() returns a value that cannot be
1687 represented as a C int, raise OverflowError.
1688
Skip Montanarof8948ca2005-09-19 03:54:46 +00001689- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001690 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001691
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001692- SF bug #893549: parsing keyword arguments was broken with a few format
1693 codes.
1694
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001695- Changes donated by Elemental Security to make it work on AIX 5.3
1696 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1697 bug #105470: test_pwd fails on 64bit system (Opteron).
1698
Guido van Rossum539c6622005-09-14 17:49:54 +00001699- Changes donated by Elemental Security to make it work on HP-UX 11 on
1700 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1701
Georg Brandl4550b8d2005-08-26 06:43:52 +00001702- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001703 (fixes bug #1119418).
1704
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001705- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1706
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001707- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1708 exceptions that cause a function to exit.
1709
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001710- The implementation of set() and frozenset() was revised to use its
1711 own internal data structure. Memory consumption is reduced by 1/3
1712 and there are modest speed-ups as well. The API is unchanged.
1713
Tim Petersde7990b2005-07-17 23:45:23 +00001714- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1715
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001716- SF bug #1229429: PyObject_CallMethod failed to decrement some
1717 reference counts in some error exit cases.
1718
Tim Petersecc6e6a2005-07-10 22:30:55 +00001719- SF bug #1185883: Python's small-object memory allocator took over
1720 a block managed by the platform C library whenever a realloc specified
1721 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001722 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001723 portable way to copy data from the C-managed block into Python's
1724 small-object space without risking a memory fault. Python's small-object
1725 realloc now leaves such blocks under the control of the platform C
1726 realloc.
1727
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001728- SF bug #1232517: An overflow error was not detected properly when
1729 attempting to convert a large float to an int in os.utime().
1730
Raymond Hettinger3296e692005-06-29 23:29:56 +00001731- SF bug #1224347: hex longs now print with lowercase letters just
1732 like their int counterparts.
1733
Michael W. Hudson188d4362005-06-20 16:52:57 +00001734- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1735 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1736 interpreter states; back out that fix and do a better job (see
1737 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1738 for a longer write-up of the problem).
1739
Michael W. Hudsondf888462005-06-03 14:41:55 +00001740- SF patch #1180995: marshal now uses a binary format by default when
1741 serializing floats.
1742
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001743- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1744 the routines that promise to produce IEEE 754 binary representations
1745 of floats now simply copy bytes around.
1746
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001747- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1748 278.
1749
Brett Cannonc3647ac2005-04-26 03:45:26 +00001750- patch #1109424: int, long, float, complex, and unicode now check for the
1751 proper magic slot for type conversions when subclassed. Previously the
1752 magic slot was ignored during conversion. Semantics now match the way
1753 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001754 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001755 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001756 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001757
Barry Warsawc8d907c2005-04-19 23:43:40 +00001758- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1759 NULL, now raise an AttributeError when attempting to set or delete the
1760 attribute. Previously a TypeError was raised, but this was inconsistent
1761 with the equivalent pure-Python implementation.
1762
Michael W. Hudson774479c2005-04-18 08:46:17 +00001763- It is now safe to call PyGILState_Release() before
1764 PyEval_InitThreads() (note that if there is reason to believe there
1765 are multiple threads around you still must call PyEval_InitThreads()
1766 before using the Python API; this fix is for extension modules that
1767 have no way of knowing if Python is multi-threaded yet).
1768
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001769- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1770 disabled caused a crash.
1771
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001772- Bug #1165306: instancemethod_new allowed the creation of a method
1773 with im_class == im_self == NULL, which caused a crash when called.
1774
Tim Petersecc6e6a2005-07-10 22:30:55 +00001775- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001776 fixes the crash seen in bug #1165761
1777
Raymond Hettinger96229b12005-03-11 06:49:40 +00001778- Added two new builtins, any() and all().

1821 current thread state when the auto-GIL-state machinery knows about
1822 it (since the thread state is being deleted, continuing to remember it
1823 can't help, but can hurt if another thread happens to get created with
1824 the same thread id).

2032 in attribute values.
2033
Anthony Baxterc51ee692006-04-01 00:57:31 +00002034- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002035 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002036 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002037 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002039- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2040 aren't officially supported here, and trying to use them will probably

2062
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002063- email 4.0 package now integrated. This is largely the same as the email 3.0
2064 package that was included in Python 2.3, except that PEP 8 module names are
2065 now used (e.g. mail.message instead of email.Message). The MIME classes
2066 have been moved to a subpackage (e.g. email.mime.text instead of
2067 email.MIMEText). The old names are still supported for now. Several
2068 deprecated Message methods have been removed and lots of bugs have been
2069 fixed. More details can be found in the email package documentation.

2072 (a subclass of tuple) that provides incremental decoders and encoders
2073 (a way to use stateful codecs without the stream API). Python functions
2074 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2075 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2076 have been added.

2079 a ValueError instead of a StopIteration now (like file and cString.String do).
2080 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2081 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002155 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2156 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2157 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2158 Ronald L. Rivest offered this advice for Python:
2159
2160 "The consensus of researchers in this area (at least as
2161 expressed at the NIST Hash Function Workshop 10/31/05),
2162 is that SHA-256 is a good choice for the time being, but
2163 that research should continue, and other alternatives may
2164 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002165

2322
Raymond Hettingerbab41432005-02-05 01:31:19 +00002323- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2324
Guido van Rossumd0641422005-02-03 15:01:24 +00002325- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2326 disables recursive traversal through instance attributes, which can
2327 be exploited in various ways.
2328
Tim Peterse3547fd2005-12-16 23:13:57 +00002329- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002330 flags on the HTTP listening socket.
2331
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002332- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2333 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2334
Fred Drakefbdeaad2006-07-29 16:56:15 +00002335- Patches #893642, #1039083: add allow_none, encoding arguments to
2336 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002337

2341
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002342- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2343
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002344- Enhancements to the csv module:
2345
2346 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002347 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002348 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002349 + Dialect parameter parsing has been re-implemented to improve error
2350 reporting.
2351 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2352 dictates.
2353 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002354 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002355 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002356 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2357 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002358 + reader now allows \r characters to be quoted (previously it only allowed
2359 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002360 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002361 + Dialect classes passed to the module are no longer instantiated by
2362 the module before being parsed (the former validation scheme required
2363 this, but the mechanism was unreliable).
2364 + The dialect registry now contains instances of the internal
2365 C-coded dialect type, rather than references to python objects.
2366 + the internal c-coded dialect type is now immutable.
2367 + register_dialect now accepts the same keyword dialect specifications
2368 as the reader and writer, allowing the user to register dialects
2369 without first creating a dialect class.
2370 + a configurable limit to the size of parsed fields has been added -
2371 previously, an unmatched quote character could result in the entire
2372 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002373 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002374 the parser field size limit (returning the former limit). The initial
2375 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002376 + A line_num attribute has been added to the reader object, which tracks
2377 the number of lines read from the source iterator. This is not
2378 the same as the number of records returned, as records can span
2379 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002380 + reader and writer objects were not being registered with the cyclic-GC.
2381 This has been fixed.
2382
Brett Cannone6539c42005-01-08 02:43:53 +00002383- _DummyThread objects in the threading module now delete self.__block that is
2384 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2385 lock primitives tend to be limited in number and thus should not be wasted on
2386 a _DummyThread object. Fixes bug #1089632.
2387
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002388- The imghdr module now detects Exif files.
2389
Raymond Hettinger6065d322004-12-20 23:51:53 +00002390- StringIO.truncate() now correctly adjusts the size attribute.
2391 (Bug #951915).
2392
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002393- locale.py now uses an updated locale alias table (built using
2394 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2395 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002396 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002397
Raymond Hettinger3557f422004-12-07 12:02:02 +00002398- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2399
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002400- the pickle module no longer accepts the deprecated None option in the
2401 args tuple returned by __reduce__().
2402
Brett Cannon84667c02004-12-07 03:25:18 +00002403- optparse now optionally imports gettext. This allows its use in setup.py.
2404
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002405- the pickle module no longer uses the deprecated bin parameter.
2406
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002407- the shelve module no longer uses the deprecated binary parameter.
2408
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002409- the pstats module no longer uses the deprecated ignore() method.
2410
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002411- the filecmp module no longer uses the deprecated use_statcache argument.
2412
Raymond Hettinger664347b2004-12-04 21:21:53 +00002413- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2414 extended or overridden by subclasses. Formerly, the subclassed method would
2415 be ignored by the rest of the module. (Bug #1078905).
2416
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002417- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002418 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002419
Walter Dörwald36733692004-12-22 12:50:50 +00002420- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2421 once when a size argument is given. This prevents a buffer overflow in the
2422 tokenizer with very long source lines.
2423
Barry Warsaw538561e2006-01-01 21:48:54 +00002424- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2425 immediately after creating the object, without any intervening
2426 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002427
Skip Montanaro05885812005-01-16 20:48:27 +00002428- The reconvert.quote function can now emit triple-quoted strings. The
2429 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002430
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002431- ``UserString.MutableString`` now supports negative indices in
2432 ``__setitem__`` and ``__delitem__``
2433
Greg Ward40407942005-03-05 02:53:17 +00002434- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2435 correctly.
2436
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002437- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2438 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2439 character even if the user has passed a size parameter to get a proper
2440 line ending. Remove the special handling of a "\r\n" that has been split
2441 between two lines.
2442
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002443- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2444 about illegal code points. The codec now supports PEP 293 style error
2445 handlers.
2446
Walter Dörwald78a78b02005-09-01 12:04:29 +00002447- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002448 from the input stream, so that the output is a byte string in the correct
2449 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002450
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002451- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2452 considering it exactly like a '*'.
2453
Walter Dörwald007f8df2005-10-09 19:42:27 +00002454- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2455 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002456
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002457- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2458
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002459- Patch #1413711: Certain patterns of differences were making difflib
2460 touch the recursion limit.
2461
Walter Dörwald58917a62006-03-31 15:26:22 +00002462- Bug #947906: An object oriented interface has been added to the calendar
2463 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002464 called as a script (e.g. via ``python -mcalendar``). Localized month and
2465 weekday names can be ouput (even if an exotic encoding is used) using
2466 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002467
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002468Build

2470
Neal Norwitz602d3392006-03-31 08:21:40 +00002471- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2472 by using -mieee gcc option.
2473

2475
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002476- Build support for Win64-AMD64 was added.
2477
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002478- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2479
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002480- Patch #881820: look for openpty and forkpty also in libbsd.
2481
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002482- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2483 The zlib module is now builtin on Windows.
2484
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002485- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2486
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002487- Bug #1189330: configure did not correctly determine the necessary
2488 value of LINKCC if python was built with GCC 4.0.
2489
Trent Mick8321b422005-07-26 02:29:21 +00002490- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2491 vulnerability in zlib 1.2.1 and 1.2.2.
2492
Brett Cannon08cd5982005-04-24 22:26:38 +00002493- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2494 flags that change binary compatibility. Changes were also made to
2495 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002496 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002497
Bob Ippolitoed233462005-03-29 13:47:59 +00002498- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2499 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2500 no longer exists). This configure patch makes things right.
2501
Martin v. Löwise2713be2005-03-08 15:03:08 +00002502- Bug #1158607: Build with --disable-unicode again.
2503
Brett Cannon46d96232005-02-16 00:07:19 +00002504- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2505 defined. Discovered as a result of not being able to build on OS X.
2506
Brett Cannon516592f2004-12-07 00:42:59 +00002507- setup.py now uses the directories specified in LDFLAGS using the -L option
2508 and in CPPFLAGS using the -I option for adding library and include
2509 directories, respectively, for compiling extension modules against. This has
2510 led to the core being compiled using the values in CPPFLAGS. It also removes
2511 the need for the special-casing of both DarwinPorts and Fink for darwin since
2512 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2513 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2514 Fink, ``-I/opt/local/include`` for DarwinPorts).
2515
Brett Cannon43802422005-02-10 20:48:03 +00002516- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2517 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2518 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2519 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002521C API
2522-----
2523
Tim Petersc9d78aa2006-03-26 23:27:58 +00002524- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2525 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2526 is obtained via the ``PyObject_`` family, it must be released via the
2527 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2528 always been officially true, but when Python's small-object allocator was
2529 introduced, an attempt was made to cater to a few extension modules
2530 discovered at the time that obtained memory via ``PyObject_New`` but
2531 released it via ``PyMem_DEL``. It's years later, and if such code still
2532 exists it will fail now (probably with segfaults, but calling wrong
2533 low-level memory management functions can yield many symptoms).
2534
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002535- Added a C API for set and frozenset objects.
2536
Raymond Hettinger66517482004-12-03 11:45:13 +00002537- Removed PyRange_New().
2538
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002539- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2540 mapping argument now. This string is used as a mapping table. Byte values
2541 greater than the length of the string and 0xFFFE are treated as undefined
2542 mappings.
