Raymond Hettinger775ebe22006-12-08 18:12:24 +000015- Bug #1456209: In some obscure cases it was possible for a class with a
16 custom ``__eq__()`` method to confuse set internals when class instances
17 were used as a set's elements and the ``__eq__()`` method mutated the set.
18
19- Eliminated unnecessary repeated calls to hash() by set.intersection() and
20 set.symmetric_difference_update().

28 both sets and dictionaries.

49
50- Fix some leftovers from the conversion from int to Py_ssize_t
51 (relevant to strings and sequences of more than 2**31 items).
52
53- A number of places, including integer negation and absolute value,
54 were fixed to not rely on undefined behaviour of the C compiler
55 anymore.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000380What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000384
385Core and builtins
386-----------------
387
Neal Norwitz24b6f202006-09-05 04:43:56 +0000388- Fix infinite recursion when subclassing long and overriding __hash__.
389
390- Fix concatenation (+=) of long strings.
391
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000392- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000393 compared equal or unequal to a string and a UnicodeDecodeError
394 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000395
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000396 Instead, the equal (==) and unequal (!=) comparison operators will
397 now issue a UnicodeWarning and interpret the two objects as
398 unequal. The UnicodeWarning can be filtered as desired using
399 the warning framework, e.g. silenced completely, turned into an
400 exception, logged, etc.
401
402 Note that compare operators other than equal and unequal will still
403 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000404
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000405- Fix segfault when doing string formatting on subclasses of long.
406
407- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
408 with new-style classes.
409
410- Fix bug related to __len__ functions returning negative values with
411 classic classes.
412
413- Patch #1538606, Fix __index__() clipping. There were some problems
414 discovered with the API and how integers that didn't fit into Py_ssize_t
415 were handled. This patch attempts to provide enough alternatives
416 to effectively use __index__.
417
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000418- Bug #1536021: __hash__ may now return long int; the final hash
419 value is obtained by invoking hash on the long int.
420
Thomas Hellerab1049c2006-08-08 17:37:00 +0000421- Bug #1536786: buffer comparison could emit a RuntimeWarning.
422
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000423- Bug #1535165: fixed a segfault in input() and raw_input() when
424 sys.stdin is closed.
425
Thomas Heller74d36f02006-08-04 18:17:40 +0000426- On Windows, the PyErr_Warn function is now exported from
427 the Python dll again.
428
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000429- Bug #1191458: tracing over for loops now produces a line event
430 on each iteration. Fixing this problem required changing the .pyc
431 magic number. This means that .pyc files generated before 2.5c1
432 will be regenerated.
433
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000434- Bug #1333982: string/number constants were inappropriately stored
435 in the byte code and co_consts even if they were not used, ie
436 immediately popped off the stack.
437
Georg Brandle9462c72006-08-04 18:03:37 +0000438- Fixed a reference-counting problem in property().

441Library
442-------
443
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000444- Fix a bug in the ``compiler`` package that caused invalid code to be
445 generated for generator expressions.
446
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000447- The distutils version has been changed to 2.5.0. The change to
448 keep it programmatically in sync with the Python version running
449 the code (introduced in 2.5b3) has been reverted. It will continue
450 to be maintained manually as static string literal.
451
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000452- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000453 and this cannot be converted to the required C type, an exception is
454 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000455 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000456
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000457- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000458 an exception.
459
Tim Peterscbdd3502006-09-05 01:47:53 +0000460- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000461 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000462 workarounds for clocks with low resolution, to stop the code yielding
463 duplicate UUIDs.
464
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000465- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
466 before raising SystemExit, allowing IDLE to honor quit() and exit().
467
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000468- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
469
Georg Brandl7a1af772006-08-14 21:55:28 +0000470- Patch #1536071: trace.py should now find the full module name of a
471 file correctly even on Windows.
472
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000473- logging's atexit hook now runs even if the rest of the module has
474 already been cleaned up.
475
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000476- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000477
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000478- Bug #1531405, format_exception no longer raises an exception if
479 str(exception) raised an exception.
480
Neil Schemenauer06ded092006-08-04 16:20:30 +0000481- Fix a bug in the ``compiler`` package that caused invalid code to be
482 generated for nested functions.

493 raises the correct exceptions.
494
Thomas Heller1ce433e2006-08-14 16:20:04 +0000495- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
496 '-no-stack-protector' compiler flag for OpenBSD has been removed.
497
Thomas Heller86720042006-08-14 11:17:48 +0000498- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
499 uses the _as_parameter_ attribute when objects are passed to foreign
500 function calls. The ctypes version number was changed to 1.0.1.
501
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000502- Bug #1530559, struct.pack raises TypeError where it used to convert.
503 Passing float arguments to struct.pack when integers are expected
504 now triggers a DeprecationWarning.
505
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000506

Neal Norwitza1f10902006-07-12 07:28:29 +0000553
554Core and builtins
555-----------------
556
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000557- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000558 returned a long (see PEP 353).
559
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000560- Bug #1515471: string.replace() accepts character buffers again.
561
Neal Norwitz07aadb12006-07-30 06:55:48 +0000562- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
563 This provides the proper warning for struct.pack().
564 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
565
Neal Norwitz0d62a062006-07-30 06:53:31 +0000566- Patch #1531113: Fix augmented assignment with yield expressions.
567 Also fix a SystemError when trying to assign to yield expressions.
568
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000569- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
570 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
571 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
572 excessive filesystem operations during imports.
573
Tim Petersbc24eee2006-07-27 01:14:53 +0000574- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
575 operations on signed longs that are formally undefined by C.
576 Unfortunately, at least one compiler now cares about that, so complicated
577 the code to make that compiler happy again.
578
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000579- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
580
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000581- Patch #1232023: Stop including current directory in search
582 path on Windows.
583
Neal Norwitze1fdb322006-07-21 05:32:28 +0000584- Fix some potential crashes found with failmalloc.
585
Neal Norwitze7563102006-07-17 01:00:16 +0000586- Fix warnings reported by Klocwork's static analysis tool.
587
Neal Norwitz84be93b2006-07-16 01:50:38 +0000588- Bug #1512814, Fix incorrect lineno's when code within a function
589 had more than 255 blank lines.
590
Georg Brandl9dceedb2006-07-12 15:31:17 +0000591- Patch #1521179: Python now accepts the standard options ``--help`` and
592 ``--version`` as well as ``/?`` on Windows.
593
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000594- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000595 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000596 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000597
Tim Peters112aad32006-07-19 00:03:19 +0000598- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000599 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000600 new ``sys._current_frames()`` returns a dictionary with one entry,
601 mapping the faux "thread id" 0 to the current frame.
602
Ronald Oussoren3075e162006-07-25 20:28:55 +0000603- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000604

608
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000609- Correction of patch #1455898: In the mbcs decoder, set final=False
610 for stream decoder, but final=True for the decode function.
611
Georg Brandl07fec3a2006-08-01 18:49:24 +0000612- os.urandom no longer masks unrelated exceptions like SystemExit or
613 KeyboardInterrupt.
614
Tim Peters4643c2f2006-08-10 22:45:34 +0000615- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000616 shutil.copytree on Windows
617
Georg Brandle34ac7c2006-07-30 11:07:23 +0000618- Bug #1002398: The documentation for os.path.sameopenfile now correctly
619 refers to file descriptors, not file objects.
620
Tim Peterscbdd3502006-09-05 01:47:53 +0000621- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000622 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000623 #1513611, and probably others.
624
Georg Brandledd9b0d2006-07-29 09:33:26 +0000625- Bug #1441397: The compiler module now recognizes module and function
626 docstrings correctly as it did in Python 2.4.
627
Tim Peters6f681472006-07-27 23:44:37 +0000628- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
629 lost that tests are sorted by name before being run. This rarely
630 matters for well-written tests, but can create baffling symptoms if
631 side effects from one test to the next affect outcomes. ``DocTestFinder``
632 has been changed to sort the list of tests it returns.
633
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000634- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000635 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000636
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000637- Bug #978833: Really close underlying socket in _socketobject.close.
638
Georg Brandldb232dc2006-08-20 13:15:43 +0000639- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
640 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000641
Georg Brandlcf0c1722006-07-26 07:23:32 +0000642- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
643 to recursive calls and call it with the failing package name.
644
Martin v. Löwis0b483032006-07-25 09:53:12 +0000645- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
646
Georg Brandlc13c34c2006-07-24 14:09:56 +0000647- Patch #1515343: Fix printing of deprecated string exceptions with a
648 value in the traceback module.
649
Greg Ward48fae7a2006-07-23 16:05:51 +0000650- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
651
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000652- Patch #1524429: Use repr() instead of backticks in Tkinter again.
653
Brett Cannoncaebe222006-07-18 04:41:36 +0000654- Bug #1520914: Change time.strftime() to accept a zero for any position in its
655 argument tuple. For arguments where zero is illegal, the value is forced to
656 the minimum value that is correct. This is to support an undocumented but
657 common way people used to fill in inconsequential information in the time
658 tuple pre-2.4.
659
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000660- Patch #1220874: Update the binhex module for Mach-O.
661
Barry Warsawb110bad2006-07-21 14:51:07 +0000662- The email package has improved RFC 2231 support, specifically for
663 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
664 (name*0=<blah>) parameter continuations. This may change the types of
665 values returned from email.message.Message.get_param() and friends.
666 Specifically in some cases where non-encoded continuations were used,
667 get_param() used to return a 3-tuple of (None, None, string) whereas now it
668 will just return the string (since non-encoded continuations don't have
669 charset and language parts).
670
671 Also, whereas % values were decoded in all parameter continuations, they are
672 now only decoded in encoded parameter parts.
673
Ronald Oussoren3075e162006-07-25 20:28:55 +0000674- Bug #1517990: IDLE keybindings on MacOS X now work correctly
675
676- Bug #1517996: IDLE now longer shows the default Tk menu when a
677 path browser, class browser or debugger is the frontmost window on MacOS X
678
Barry Warsaw00decd72006-07-27 23:43:15 +0000679- Patch #1520294: Support for getset and member descriptors in types.py,
680 inspect.py, and pydoc.py. Specifically, this allows for querying the type
681 of an object against these built-in types and more importantly, for getting
682 their docstrings printed in the interactive interpreter's help() function.

686-----------------
687
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000688- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
689 a socket operation on a socket with a timeout, the exception will be
690 caught correctly. Previously, the exception was not caught.
691
Thomas Heller1393d6a2006-07-28 21:43:20 +0000692- Patch #1529514: The _ctypes extension is now compiled on more
693 openbsd target platforms.
694
Tim Peters9cab5932006-07-28 00:30:00 +0000695- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
696 a memory leak, affecting pickles and deep copies.
697
Tim Petersbc24eee2006-07-27 01:14:53 +0000698- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

700
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000701- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
702
Thomas Hellerce049a02006-07-14 17:51:14 +0000703- Patch #1521817: Index range checking on ctypes arrays containing
704 exactly one element enabled again. This allows iterating over these
705 arrays, without the need to check the array size before.
706
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000707- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000708 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000709 /dev/null in certain cases; this is now fixed.
710
Thomas Heller47d7a062006-07-12 08:43:47 +0000711- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
712 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000713
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000714- Because of a misspelled preprocessor symbol, ctypes was always
715 compiled without thread support; this is now fixed.
716
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000717- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
718 methods now allow their database parameter to be None as the
719 sleepycat API allows.
720
Matt Flemingec926502006-07-28 11:27:27 +0000721- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
722 bluetooth API compared with Linux and FreeBSD.
723
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000724Tests
725-----
726
727- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
728 how long the test file should take to play. Now accepts taking 2.93 secs
729 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
730
Georg Brandl4793aa32006-07-28 18:31:39 +0000731- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
732 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
733 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000734
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000735Build

737
738- Bug #1439538: Drop usage of test -e in configure as it is not portable.
739
Ronald Oussoren26cad082006-08-01 21:00:57 +0000740Mac
741---
742
743- PythonLauncher now works correctly when the path to the script contains
744 characters that are treated specially by the shell (such as quotes).
745
746- Bug #1527397: PythonLauncher now launches scripts with the working directory
747 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000748 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000749 expect.

757Core and builtins
758-----------------
759
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000760- Bug #1441486: The literal representation of -(sys.maxint - 1)
761 again evaluates to a int object, not a long.
762
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000763- Bug #1501934: The scope of global variables that are locally assigned
764 using augmented assignment is now correctly determined.
765
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000766- Bug #927248: Recursive method-wrapper objects can now safely
767 be released.
768
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000769- Bug #1417699: Reject locale-specific decimal point in float()
770 and atof().
771
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000772- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
773 omit a default "error" argument for NULL pointer. This allows
774 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000775
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000776- Bug #1519018: 'as' is now validated properly in import statements.
777
Neal Norwitz28746ab2006-07-09 22:14:42 +0000778- On 64 bit systems, int literals that use less than 64 bits are
779 now ints rather than longs.
780
Neal Norwitzed657552006-07-10 00:04:44 +0000781- Bug #1512814, Fix incorrect lineno's when code at module scope
782 started after line 256.
783
Tim Peters32a83612006-07-10 21:08:24 +0000784- New function ``sys._current_frames()`` returns a dict mapping thread
785 id to topmost thread stack frame. This is for expert use, and is
786 especially useful for debugging application deadlocks. The functionality
787 was previously available in Fazal Majid's ``threadframe`` extension
788 module, but it wasn't possible to do this in a wholly threadsafe way from
789 an extension.

792-------
793
Martin v. Löwis77621582006-07-30 13:27:31 +0000794- Bug #1257728: Mention Cygwin in distutils error message about a missing

Tim Peters32a83612006-07-10 21:08:24 +0000799- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000800 environment variable to be set in order to the SDK environment
801 for finding the compiler, include files, etc.

806
Thomas Woutersadd19112006-07-05 11:03:49 +0000807- string.Template() now correctly handles tuple-values. Previously,
808 multi-value tuples would raise an exception and single-value tuples would
809 be treated as the value they contain, instead.
810
Martin v. Löwisede77f52006-07-03 13:01:35 +0000811- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
812 even if some data are received.
813
Martin v. Löwis45482392006-07-03 12:28:58 +0000814- Bug #1267547: Put proper recursive setup.py call into the

818 degrees and radians.
819
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000820- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000821 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000822
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000823- Bug #1514703: Only setup canvas window in turtle when the canvas
824 is created.
825

830 attribute values.
831
832- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
833 sgmllib ('[' and ']' were not accepted).
834
Georg Brandl1be63af2006-06-28 20:23:25 +0000835- Fix a bug in the turtle module's end_fill function.
836
Brett Cannon53ab5b72006-06-22 16:49:14 +0000837- Bug #1510580: The 'warnings' module improperly required that a Warning
838 category be either a types.ClassType and a subclass of Warning. The proper
839 check is just that it is a subclass with Warning as the documentation states.
840
Georg Brandlad29e632006-06-21 17:45:17 +0000841- The compiler module now correctly compiles the new try-except-finally
842 statement (bug #1509132).
843
Neal Norwitz60373cd2006-06-22 06:30:50 +0000844- The wsgiref package is now installed properly on Unix.
845
Vinay Sajip28e57612006-07-01 10:45:20 +0000846- A bug was fixed in logging.config.fileConfig() which caused a crash on
847 shutdown when fileConfig() was called multiple times.
848
Gerhard Häring762fbd32006-07-02 17:48:30 +0000849- The sqlite3 module did cut off data from the SQLite database at the first
850 null character before sending it to a custom converter. This has been fixed
851 now.
852

854-----------------
855
Tim Peters112aad32006-07-19 00:03:19 +0000856- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
857 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
858 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000859
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000860- Assigning None to pointer type fields in ctypes structures possible
861 overwrote the wrong fields, this is fixed now.
862
863- Fixed a segfault in _ctypes when ctypes.wintypes were imported
864 on non-Windows platforms.
865
866- Bug #1518190: The ctypes.c_void_p constructor now accepts any
867 integer or long, without range checking.
868
869- Patch #1517790: It is now possible to use custom objects in the ctypes
870 foreign function argtypes sequence as long as they provide a from_param
871 method, no longer is it required that the object is a ctypes type.
872
873- The '_ctypes' extension module now works when Python is configured
874 with the --without-threads option.
875
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000876- Bug #1513646: os.access on Windows now correctly determines write
877 access, again.
878
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000879- Bug #1512695: cPickle.loads could crash if it was interrupted with

891
Tim Peters32a83612006-07-10 21:08:24 +0000892- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000893 Previously, the slight difference could cause compilation errors of the
894 'zlib' module on systems with more than one version of zlib.
895
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000896- The MSI compileall step was fixed to also support a TARGETDIR

915 documentation for the warnings module.
916
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000917- Patch #1509163: MS Toolkit Compiler no longer available.
918

927Core and builtins
928-----------------
929
Georg Brandla56b9152006-06-19 06:35:54 +0000930- Patch #1507676: Error messages returned by invalid abstract object operations
931 (such as iterating over an integer) have been improved and now include the
932 type of the offending object to help with debugging.
933
Brett Cannonea3912b2006-06-13 21:46:41 +0000934- Bug #992017: A classic class that defined a __coerce__() method that returned
935 its arguments swapped would infinitely recurse and segfault the interpreter.
936
Neal Norwitz909eb122006-06-12 02:13:21 +0000937- Fix the socket tests so they can be run concurrently.
938
Neal Norwitzb9845e72006-06-12 02:11:18 +0000939- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000940 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000941
Brett Cannon22565aa2006-06-09 22:31:23 +0000942- Bug #532646: object.__call__() will continue looking for the __call__
943 attribute on objects until one without one is found. This leads to recursion
944 when you take a class and set its __call__ attribute to an instance of the
945 class. Originally fixed for classic classes, but this fix is for new-style.
946 Removes the infinite_rec_3 crasher.
947
Georg Brandl24250812006-06-09 18:45:48 +0000948- The string and unicode methods startswith() and endswith() now accept
949 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
950
Brett Cannonde3b0522006-06-08 17:00:45 +0000951- Buffer objects, at the C level, never used the char buffer
952 implementation even when the char buffer for the wrapped object was
953 explicitly requested (originally returned the read or write buffer).
954 Now a TypeError is raised if the char buffer is not present but is
955 requested.
956
Georg Brandlddbaa662006-06-04 21:56:52 +0000957- Patch #1346214: Statements like "if 0: suite" are now again optimized
958 away like they were in Python 2.4.
959
Georg Brandlb7c8f542006-05-27 12:30:25 +0000960- Builtin exceptions are now full-blown new-style classes instead of
961 instances pretending to be classes, which speeds up exception handling
962 by about 80% in comparison to 2.5a2.
963
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000964- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
965 Unicode 4.1.
966
Georg Brandlf4ef1162006-05-26 18:03:31 +0000967- Patch #921466: sys.path_importer_cache is now used to cache valid and
968 invalid file paths for the built-in import machinery which leads to
969 fewer open calls on startup.
970
Tim Peters696cf432006-05-24 21:10:40 +0000971- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
972 of-2 bases. The largest speedup is for inputs with about 1000 decimal
973 digits. Conversion from non-power-of-2 bases remains quadratic-time in
974 the number of input digits (it was and remains linear-time for bases
975 2, 4, 8, 16 and 32).
976
Tim Petersb713ec22006-05-23 18:45:30 +0000977- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
978 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
979 an integer close to ``sys.maxint``. This was repaired by patch
980 #1335972, which also gives a nice speedup.
981
Richard Jonescebbefc2006-05-23 18:28:17 +0000982- Patch #1337051: reduced size of frame objects.
983
984- PyErr_NewException now accepts a tuple of base classes as its
985 "base" parameter.
986
Richard Jones7c88dcc2006-05-23 10:37:38 +0000987- Patch #876206: function call speedup by retaining allocated frame
988 objects.
989
Georg Brandl7b90e162006-05-18 07:01:27 +0000990- Bug #1462152: file() now checks more thoroughly for invalid mode
991 strings and removes a possible "U" before passing the mode to the
992 C library function.
993
Neal Norwitz1004a532006-05-15 07:17:23 +0000994- Patch #1488312, Fix memory alignment problem on SPARC in unicode
995
Neal Norwitz373f0a72006-05-15 07:04:36 +0000996- Bug #1487966: Fix SystemError with conditional expression in assignment
997
Martin v. Löwis879768d2006-05-11 13:28:43 +0000998- WindowsError now has two error code attributes: errno, which carries
999 the error values from errno.h, and winerror, which carries the error
1000 values from winerror.h. Previous versions put the winerror.h values
1001 (from GetLastError()) into the errno attribute.
1002
Martin v. Löwis77736712006-05-04 05:51:03 +00001003- Patch #1475845: Raise IndentationError for unexpected indent.
1004
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001005- Patch #1479181: split open() and file() from being aliases for each other.
1006
Tim Peters44bd9862006-06-01 13:49:23 +00001007- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1008 methods were always silently ignored by dictionaries when comparing keys.
1009 They are now passed through (except when using the C API function
1010 ``PyDict_GetItem()``, whose semantics did not change).
1011
1012- Bug #1456209: In some obscure cases it was possible for a class with a
1013 custom ``__eq__()`` method to confuse dict internals when class instances
1014 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1015 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001017Extension Modules
1018-----------------
1019
Trent Mick960a3f82006-06-28 20:30:41 +00001020- Bug #1295808: expat symbols should be namespaced in pyexpat
1021
1022- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1023
Brett Cannon6ee7d012006-06-08 16:23:04 +00001024- Change binascii.hexlify to accept a read-only buffer instead of only a char
1025 buffer and actually follow its documentation.
1026
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001027- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1028
Nick Coghlanc649ec52006-05-29 12:43:05 +00001029- Patch #1478788 (modified version): The functional extension module has
1030 been renamed to _functools and a functools Python wrapper module added.
1031 This provides a home for additional function related utilities that are
1032 not specifically about functional programming. See PEP 309.
1033
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001034- Patch #1493701: performance enhancements for struct module.
1035
Georg Brandl378d5922006-05-17 14:26:50 +00001036- Patch #1490224: time.altzone is now set correctly on Cygwin.
1037
Georg Brandl8d3342b2006-05-16 07:38:27 +00001038- Patch #1435422: zlib's compress and decompress objects now have a
1039 copy() method.
1040
Andrew MacIntyre92913322006-06-13 15:04:24 +00001041- Patch #1454481: thread stack size is now tunable at runtime for thread
1042 enabled builds on Windows and systems with Posix threads support.
1043
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001044- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1045 (up to the system limit of 32K characters).
1046
1047- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1048 As a result, these functions now raise WindowsError instead of OSError.
1049
Tim Peters7a822da2006-05-25 21:50:17 +00001050- ``time.clock()`` on Win64 should use the high-performance Windows
1051 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1052 Windows platforms).
1053
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001054- Calling Tk_Init twice is refused if the first call failed as that
1055 may deadlock.
1056
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001057- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1058 accept it without potentially using an uninitialized pointer.
1059
1060- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1061 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1062 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001063
Gregory P. Smith372b5832006-06-05 18:48:21 +00001064- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001065 [pybsddb project SF patch number 1466734]
1066
Gregory P. Smith372b5832006-06-05 18:48:21 +00001067- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1068 parameter is supplied. [SF pybsddb bug #1477863]
1069
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001070- bsddb: the __len__ method of a DB object has been fixed to return correct
1071 results. It could previously incorrectly return 0 in some cases.
1072 Fixes SF bug 1493322 (pybsddb bug 1184012).
1073
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001074- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1075 aborts the db transaction safely when a modifier callback fails.
1076 Fixes SF python patch/bug #1408584.
1077
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001078- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001079 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001080 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1081 database calls that would previously deadlock. [SF python bug #775414]
1082
Vinay Sajip28e57612006-07-01 10:45:20 +00001083- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001084
Walter Dörwald4994d952006-06-19 08:07:50 +00001085- Patch #1506645: add Python wrappers for the curses functions
1086 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001091- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1092 functions.
1093
Martin v. Löwis3798da02006-06-17 18:44:27 +00001094- Patch #812986: Update turtle output even if not tracing.
1095
Vinay Sajip28e57612006-07-01 10:45:20 +00001096- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001097 Tkinter.BaseWidget.
1098
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001099- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1100
Martin v. Löwis337487e2006-06-17 09:15:14 +00001101- Patch #763580: Add name and value arguments to Tkinter variable
1102 classes.
1103
Georg Brandl83cc0d02006-06-14 08:50:03 +00001104- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1105 mime.types file for determining MIME types.
1106
Georg Brandl2605ca82006-06-14 06:08:31 +00001107- Bug #1339007: Shelf objects now don't raise an exception in their
1108 __del__ method when initialization failed.
1109
Martin v. Löwisd8251432006-06-14 05:21:04 +00001110- Patch #1455898: The MBCS codec now supports the incremental mode for
1111 double-byte encodings.
1112
Tim Peters43898b42006-06-14 04:09:25 +00001113- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1114 guarantee that adjacent triples in the return list always describe
1115 non-adjacent blocks. Previously, a pair of matching blocks could end
1116 up being described by multiple adjacent triples that formed a partition
1117 of the matching pair.
1118
Greg Ward0e0c9f42006-06-11 16:24:11 +00001119- Bug #1498146: fix optparse to handle Unicode strings in option help,
1120 description, and epilog.
1121
Greg Wardd1c797e2006-06-11 14:42:41 +00001122- Bug #1366250: minor optparse documentation error.
1123
Greg Ward7f547402006-06-11 00:40:49 +00001124- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1125 clarify docs.
1126
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001127- The wsgiref package has been added to the standard library.
1128
Nick Coghlan676725d2006-06-08 13:54:49 +00001129- The functions update_wrapper() and wraps() have been added to the functools
1130 module. These make it easier to copy relevant metadata from the original
1131 function when writing wrapper functions.
1132
Tim Petersd6a9eef2006-06-05 01:48:21 +00001133- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1134 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001135
Martin v. Löwis3f767792006-06-04 19:36:28 +00001136- Patch #1359618: Speed up charmap encoder by using a trie structure
1137 for lookup.
1138
Tim Petersd609b1a2006-06-02 23:22:51 +00001139- The functions in the ``pprint`` module now sort dictionaries by key
1140 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1141 if and only if its display required more than one line, although that
1142 wasn't documented. The new behavior increases predictability; e.g.,
1143 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1144
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001145- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1146 (thanks for J. J. Lee).
1147
Georg Brandl2b330372006-05-28 20:23:12 +00001148- Patch #1496206: improve urllib2 handling of passwords with respect to
1149 default HTTP and HTTPS ports.
1150
George Yoshidaf3c65de2006-05-28 16:39:09 +00001151- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1152
Bob Ippolito7298f272006-05-23 18:43:47 +00001153- Patch #1281707: speed up gzip.readline.
1154
Georg Brandlb89316f2006-05-17 15:51:16 +00001155- Patch #1180296: Two new functions were added to the locale module:
1156 format_string() to get the effect of "format % items" but locale-aware,
1157 and currency() to format a monetary number with currency sign.
1158
Georg Brandle3a25832006-05-17 14:56:04 +00001159- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1160 and several features added, such as speed and geometry control.
1161
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001162- Patch #1488881: add support for external file objects in bz2 compressed
1163 tarfiles.
1164
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001165- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1166 stdout arguments, making it possible to redirect input and output
1167 for remote debugging.
1168
1169- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1170 a couple of issues, notably handling of long file names using the
1171 GNU LONGNAME extension.
1172
1173- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1174 new flag when ``name`` is already the name of an option flag.
1175
1176- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1177 package.
1178
1179- Patch #1472854: make the rlcompleter.Completer class usable on non-
1180 UNIX platforms.
1181
1182- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1183
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001184- Bug #1472827: correctly escape newlines and tabs in attribute values in
1185 the saxutils.XMLGenerator class.

Thomas Heller1b046642006-04-18 18:51:06 +00001223- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1224 by converting these apis from macros into exported functions again:
1225
1226 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1227 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1228 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1229 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1230 PyRun_String Py_CompileString
1231
Martin v. Löwis45294a92006-04-18 06:24:08 +00001232- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1233
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001234- All uses of PyStructSequence_InitType have been changed to initialize
1235 the type objects only once, even if the interpreter is initialized
1236 multiple times.
1237
Neal Norwitz61546162006-04-14 05:20:28 +00001238- Bug #1454485, array.array('u') could crash the interpreter. This was
1239 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1240 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1241
1242- Py_UNICODE is unsigned. It was always documented as unsigned, but
1243 due to a bug had a signed value in previous versions.
1244
Tim Peters3a5e8b12006-04-11 01:44:07 +00001245- Patch #837242: ``id()`` of any Python object always gives a positive
1246 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1247 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001248 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001249 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001250
Tim Peters3a5e8b12006-04-11 01:44:07 +00001251 def __hash__(self):
1252 return id(self) # WRONG
1253
1254 because a hash result must be a (short) Python int but it was always
1255 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001256 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001257 was always usable as a hash value before this patch. That's no longer
1258 necessarily so.
1259
1260- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001261 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001262 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001263 #1454844)
1264
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001265- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1266 involving generators that have paused outside of any ``try`` or ``with``
1267 blocks. (In 2.5a1, a paused generator that was part of a reference
1268 cycle could not be garbage collected, regardless of whether it was
1269 paused in a ``try`` or ``with`` block.)

1273
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001274- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1275 is a macro.
1276
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001277- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1278 fails with an error condition.
1279
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001280- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1281
1282- Bug #1117761: bsddb.*open() no longer raises an exception when using
1283 the cachesize parameter.
1284
1285- Bug #1149413: bsddb.*open() no longer raises an exception when using
1286 a temporary db (file=None) with the 'n' flag to truncate on open.
1287
1288- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1289 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001290
Armin Rigoa9017c32006-04-19 11:50:27 +00001291- Patch #1062014: AF_UNIX sockets under Linux have a special
1292 abstract namespace that is now fully supported.
1293
Anthony Baxter51bcb682006-04-05 14:51:42 +00001294Library
1295-------
1296
Peter Astrand7d1d4362006-07-14 14:04:45 +00001297- Bug #1223937: subprocess.CalledProcessError reports the exit status
1298 of the process using the returncode attribute, instead of
1299 abusing errno.
1300
Tim Peters711bf302006-04-25 03:31:36 +00001301- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1302 a doctest to be skipped (the code is not run, and the expected output
1303 or exception is ignored).
1304
Nick Coghlanda2268f2006-04-24 04:37:15 +00001305- Fixed contextlib.nested to cope with exceptions being raised and
1306 caught inside exit handlers.
1307
Greg Wardab05edc2006-04-23 03:47:58 +00001308- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1309 hex, octal, or binary; add ``append_const`` action; keep going if
1310 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1311 added ``epilog`` for better help generation).
1312
Tim Peters21fbd572006-04-21 21:18:10 +00001313- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1314 called from a thread spawned as a side effect of importing a module.
1315
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001316- The pydoc module now supports documenting packages contained in
1317 .zip or .egg files.
1318
1319- The pkgutil module now has several new utility functions, such
1320 as ``walk_packages()`` to support working with packages that are either
1321 in the filesystem or zip files.
1322
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001323- The mailbox module can now modify and delete messages from
1324 mailboxes, in addition to simply reading them. Thanks to Gregory
1325 K. Johnson for writing the code, and to the 2005 Google Summer of
1326 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001327
Tim Petersc7605f22006-04-17 21:12:33 +00001328- The ``__del__`` method of class ``local`` in module ``_threading_local``
1329 returned before accomplishing any of its intended cleanup.
1330
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001331- Patch #790710: Add breakpoint command lists in pdb.
1332
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001333- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1334
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001335- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1336
Anthony Baxtere29002c2006-04-12 12:07:31 +00001337- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1338 Windows. Bug #1469163.
1339
Phillip J. Eby47032112006-04-11 01:07:43 +00001340- The warnings, linecache, inspect, traceback, site, and doctest modules
1341 were updated to work correctly with modules imported from zipfiles or
1342 via other PEP 302 __loader__ objects.
1343
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001344- Patch #1467770: Reduce usage of subprocess._active to processes which
1345 the application hasn't waited on.
1346
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001347- Patch #1462222: Fix Tix.Grid.
1348
Neal Norwitza31bf182006-04-09 03:35:43 +00001349- Fix exception when doing glob.glob('anything*/')
1350
Skip Montanaro262fb922006-04-21 02:31:07 +00001351- The pstats.Stats class accepts an optional stream keyword argument to
1352 direct output to an alternate file-like object.
1353
Anthony Baxter51bcb682006-04-05 14:51:42 +00001354Build
1355-----
1356
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001357- The Makefile now has a reindent target, which runs reindent.py on
1358 the library.
1359
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001360- Patch #1470875: Building Python with MS Free Compiler
1361
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001362- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001363
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001364- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1365 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001366 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001367 CXX from --with-cxx-main, see description in README.
1368
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001369- Patch #1429775: Link extension modules with the shared libpython.
1370
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001371- Fixed a libffi build problem on MIPS systems.
1372
Tim Peters8931ff12006-05-13 23:28:20 +00001373- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1374 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1375 and "%zu" for unsigned integers of type ``size_t``.
1376
Anthony Baxter51bcb682006-04-05 14:51:42 +00001377Tests
1378-----
1379
Nick Coghlanda2268f2006-04-24 04:37:15 +00001380- test_contextlib now checks contextlib.nested can cope with exceptions
1381 being raised and caught inside exit handlers.
1382
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001383- test_cmd_line now checks operation of the -m and -c command switches
1384
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001385- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1386 it separately and by hand. It also wasn't cleaning up its changes to
1387 the current Decimal context.
1388
Thomas Woutersabd08882006-04-26 15:53:30 +00001389- regrtest.py now has a -M option to run tests that test the new limits of
1390 containers, on 64-bit architectures. Running these tests is only sensible
1391 on 64-bit machines with more than two gigabytes of memory. The argument
1392 passed is the maximum amount of memory for the tests to use.
1393
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001394Tools
1395-----
1396
1397- Added the Python benchmark suite pybench to the Tools/ directory;
1398 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001400Documentation
1401-------------
1402
Tim Petersb06d28c2006-05-12 01:57:59 +00001403- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1404
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001405- PEP 343: Added Context Types section to the library reference
1406 and attempted to bring other PEP 343 related documentation into
1407 line with the implementation and/or python-dev discussions.
1408
Tim Peters8dc73d22006-04-24 02:03:16 +00001409- Bug #1337990: clarified that ``doctest`` does not support examples
1410 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001413What's New in Python 2.5 alpha 1?
1414=================================
1415
Anthony Baxterebed3f62006-04-03 15:03:44 +00001416*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001417
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001418Core and builtins
1419-----------------
1420
Nick Coghlan43832302006-04-23 17:04:07 +00001421- PEP 338: -m command line switch now delegates to runpy.run_module
1422 allowing it to support modules in packages and zipfiles
1423
Martin v. Löwisc661b882006-04-20 04:54:23 +00001424- On Windows, .DLL is not an accepted file name extension for
1425 extension modules anymore; extensions are only found if they
1426 end in .PYD.
1427
Martin v. Löwisea62d252006-04-03 10:56:49 +00001428- Bug #1421664: sys.stderr.encoding is now set to the same value as
1429 sys.stdout.encoding.
1430
Neal Norwitz92e212f2006-04-03 04:48:37 +00001431- __import__ accepts keyword arguments.
1432
Georg Brandlccadf842006-03-31 18:54:53 +00001433- Patch #1460496: round() now accepts keyword arguments.
1434
Anthony Baxter262c00a2006-03-30 10:53:17 +00001435- Fixed bug #1459029 - unicode reprs were double-escaped.
1436
Hye-Shik Changd478f342006-03-23 12:32:36 +00001437- Patch #1396919: The system scope threads are reenabled on FreeBSD
1438 5.4 and later versions.
1439
Neal Norwitze98ccf62006-03-23 05:39:47 +00001440- Bug #1115379: Compiling a Unicode string with an encoding declaration
1441 now gives a SyntaxError.
1442
Georg Brandlabd1ff82006-03-18 07:59:59 +00001443- Previously, Python code had no easy way to access the contents of a
1444 cell object. Now, a ``cell_contents`` attribute has been added
1445 (closes patch #1170323).
1446
Tim Peterscf79aac2006-03-16 01:14:46 +00001447- Patch #1123430: Python's small-object allocator now returns an arena to
1448 the system ``free()`` when all memory within an arena becomes unused
1449 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1450 freed. Some applications will see a drop in virtual memory size now,
1451 especially long-running applications that, from time to time, temporarily
1452 use a large number of small objects. Note that when Python returns an
1453 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001454 platform C library will in turn return that memory to the operating system.
1455 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001456 appears to be effective at least on Microsoft C and gcc-based systems.
1457 Thanks to Evan Jones for hard work and patience.
1458
Georg Brandl533ff6f2006-03-08 18:09:27 +00001459- Patch #1434038: property() now uses the getter's docstring if there is
1460 no "doc" argument given. This makes it possible to legitimately use
1461 property() as a decorator to produce a read-only property.
1462
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001463- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1464 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1465 of requiring an int or long in slicing and a few other contexts, enabling
1466 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1467
Neal Norwitz995acdf2006-03-07 05:01:00 +00001468- Fixed various bugs reported by Coverity's Prevent tool.
1469
Brett Cannonbf364092006-03-01 04:25:17 +00001470- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1471 new exception base class, BaseException, which has a new message attribute.
1472 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1473 Raising a string exception now raises a DeprecationWarning.
1474
Thomas Woutersfb609f42006-02-28 16:37:25 +00001475- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1476 explicitly relative, using 'from .module import name' to mean 'from the same
1477 package as this module is in. Imports without dots still default to the
1478 old relative-then-absolute, unless 'from __future__ import
1479 absolute_import' is used.
1480
Brett Cannona7446e32006-02-27 23:39:10 +00001481- Properly check if 'warnings' raises an exception (usually when a filter set
1482 to "error" is triggered) when raising a warning for raising string
1483 exceptions.
1484
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001485- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001486 The name was removed from Include/code.h.
1487
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001488- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001489
Guido van Rossum1968ad32006-02-25 22:38:04 +00001490- Patch 1433928:
1491 - The copy module now "copies" function objects (as atomic objects).
1492 - dict.__getitem__ now looks for a __missing__ hook before raising
1493 KeyError.
1494
Tim Peters84ef21c2006-02-28 20:39:06 +00001495- PEP 343: with statement implemented. Needs ``from __future__ import
1496 with_statement``. Use of 'with' as a variable will generate a warning.
1497 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001498 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001499 The following objects have __context__ methods:
1500 - The built-in file type.
1501 - The thread.LockType type.
1502 - The following types defined by the threading module:
1503 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1504 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001505
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001506- Fix the encodings package codec search function to only search
1507 inside its own package. Fixes problem reported in patch #1433198.
1508
1509 Note: Codec packages should implement and register their own
1510 codec search function. PEP 100 has the details.
1511
Tim Peters9ea89d22006-06-04 03:26:02 +00001512- PEP 353: Using ``Py_ssize_t`` as the index type.
1513
1514- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1515 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1516 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1517 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1518 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001519
Neal Norwitzfc76d632006-01-10 06:03:13 +00001520- Patch #1400181, fix unicode string formatting to not use the locale.
1521 This is how string objects work. u'%f' could use , instead of .
1522 for the decimal point. Now both strings and unicode always use periods.
1523
Neal Norwitz671b9e32006-01-09 07:07:12 +00001524- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1525 configure would break checking curses.h.
1526
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001527- Bug #959576: The pwd module is now builtin. This allows Python to be
1528 built on UNIX platforms without $HOME set.
1529
Neal Norwitzc10978f2005-12-19 06:07:16 +00001530- Bug #1072182, fix some potential problems if characters are signed.
1531
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001532- Bug #889500, fix line number on SyntaxWarning for global declarations.
1533
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001534- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1535
Neal Norwitze7214a12005-12-18 05:03:17 +00001536- Support for converting hex strings to floats no longer works.
1537 This was not portable. float('0x3') now raises a ValueError.
1538
Barry Warsaw2a38a862005-12-18 01:27:35 +00001539- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001540 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001541 is now displayed in interactive prompt banner.
1542
Georg Brandlfa166682005-12-17 21:45:17 +00001543- Implementation of PEP 341 - Unification of try/except and try/finally.
1544 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001545 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001546
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001547- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1548 now encodes backslash correctly.
1549
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001550- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1551
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001552- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001553 and long longs.
1554
Neal Norwitz67715f02005-11-09 06:59:35 +00001555- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001556 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001557 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001558
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001559- Replaced most Unicode charmap codecs with new ones using the
1560 new Unicode translate string feature in the builtin charmap
1561 codec; the codecs were created from the mapping tables available
1562 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1563 encodings now include a mapping for the Apple logo)
1564
Tim Peterse3547fd2005-12-16 23:13:57 +00001565- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001566
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001567- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001568
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001569- A new AST parser implementation was completed. The abstract
1570 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001571 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001572
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001573- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001574 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1575
Neal Norwitz708e51a2005-10-03 04:48:15 +00001576- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1577
Neal Norwitz11bd1192005-10-03 00:54:56 +00001578- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1579 Provide a warning when a directory is passed on the command line.
1580
Neal Norwitz40d37812005-10-02 01:48:49 +00001581- Fix segfault with invalid coding.
1582
1583- SF bug #772896: unknown encoding results in MemoryError.
1584
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001585- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001586 supported a __len__() method which evaluated to False when the iterator
1587 was empty.
1588
Guido van Rossum630db602005-09-20 18:49:54 +00001589- On 64-bit platforms, when __len__() returns a value that cannot be
1590 represented as a C int, raise OverflowError.
1591
Skip Montanarof8948ca2005-09-19 03:54:46 +00001592- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001593 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001594
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001595- SF bug #893549: parsing keyword arguments was broken with a few format
1596 codes.
1597
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001598- Changes donated by Elemental Security to make it work on AIX 5.3
1599 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1600 bug #105470: test_pwd fails on 64bit system (Opteron).
1601
Guido van Rossum539c6622005-09-14 17:49:54 +00001602- Changes donated by Elemental Security to make it work on HP-UX 11 on
1603 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1604
Georg Brandl4550b8d2005-08-26 06:43:52 +00001605- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001606 (fixes bug #1119418).
1607
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001608- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1609
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001610- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1611 exceptions that cause a function to exit.
1612
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001613- The implementation of set() and frozenset() was revised to use its
1614 own internal data structure. Memory consumption is reduced by 1/3
1615 and there are modest speed-ups as well. The API is unchanged.
1616
Tim Petersde7990b2005-07-17 23:45:23 +00001617- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1618
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001619- SF bug #1229429: PyObject_CallMethod failed to decrement some
1620 reference counts in some error exit cases.
1621
Tim Petersecc6e6a2005-07-10 22:30:55 +00001622- SF bug #1185883: Python's small-object memory allocator took over
1623 a block managed by the platform C library whenever a realloc specified
1624 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001625 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001626 portable way to copy data from the C-managed block into Python's
1627 small-object space without risking a memory fault. Python's small-object
1628 realloc now leaves such blocks under the control of the platform C
1629 realloc.
1630
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001631- SF bug #1232517: An overflow error was not detected properly when
1632 attempting to convert a large float to an int in os.utime().
1633
Raymond Hettinger3296e692005-06-29 23:29:56 +00001634- SF bug #1224347: hex longs now print with lowercase letters just
1635 like their int counterparts.
1636
Michael W. Hudson188d4362005-06-20 16:52:57 +00001637- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1638 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1639 interpreter states; back out that fix and do a better job (see
1640 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1641 for a longer write-up of the problem).
1642
Michael W. Hudsondf888462005-06-03 14:41:55 +00001643- SF patch #1180995: marshal now uses a binary format by default when
1644 serializing floats.
1645
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001646- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1647 the routines that promise to produce IEEE 754 binary representations
1648 of floats now simply copy bytes around.
1649
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001650- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1651 278.
1652
Brett Cannonc3647ac2005-04-26 03:45:26 +00001653- patch #1109424: int, long, float, complex, and unicode now check for the
1654 proper magic slot for type conversions when subclassed. Previously the
1655 magic slot was ignored during conversion. Semantics now match the way
1656 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001657 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001658 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001659 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001660
Barry Warsawc8d907c2005-04-19 23:43:40 +00001661- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1662 NULL, now raise an AttributeError when attempting to set or delete the
1663 attribute. Previously a TypeError was raised, but this was inconsistent
1664 with the equivalent pure-Python implementation.
1665
Michael W. Hudson774479c2005-04-18 08:46:17 +00001666- It is now safe to call PyGILState_Release() before
1667 PyEval_InitThreads() (note that if there is reason to believe there
1668 are multiple threads around you still must call PyEval_InitThreads()
1669 before using the Python API; this fix is for extension modules that
1670 have no way of knowing if Python is multi-threaded yet).
1671
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001672- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1673 disabled caused a crash.
1674
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001675- Bug #1165306: instancemethod_new allowed the creation of a method
1676 with im_class == im_self == NULL, which caused a crash when called.
1677
Tim Petersecc6e6a2005-07-10 22:30:55 +00001678- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001679 fixes the crash seen in bug #1165761
1680
Raymond Hettinger96229b12005-03-11 06:49:40 +00001681- Added two new builtins, any() and all().
1682
Brett Cannon409d8f22005-03-05 06:47:57 +00001683- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001684 (e.g., ``class C(): pass`` is no longer a syntax error).
1685 Patch #1176012 added support to the 'parser' module and 'compiler' package
1686 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001687
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001688- Patch #1115086: Support PY_LONGLONG in structmember.
1689
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001690- Bug #1155938: new style classes did not check that __init__() was
1691 returning None.
1692
Tim Petersecc6e6a2005-07-10 22:30:55 +00001693- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001694 ('\') with a specific error message.
1695
Martin v. Löwisff232d72005-03-03 09:24:38 +00001696- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1697
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001698- Bug #1124295: the __name__ attribute of file objects was
1699 inadvertently made inaccessible in restricted mode.
1700
Tim Petersecc6e6a2005-07-10 22:30:55 +00001701- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001702 an ferror() call.
1703
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001704- min() and max() now support key= arguments with the same meaning as in
1705 list.sort().
1706
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001707- The peephole optimizer now performs simple constant folding in expressions:
1708 (2+3) --> (5).
1709
Raymond Hettingera422c342005-01-11 03:03:27 +00001710- set and frozenset objects can now be marshalled. SF #1098985.
1711
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001712- Bug #1077106: Poor argument checking could cause memory corruption
1713 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001714
Jeremy Hyltonab630502005-02-04 18:44:06 +00001715- The parser did not complain about future statements in illegal
1716 positions. It once again reports a syntax error if a future
1717 statement occurs after anything other than a doc string.
1718
Neil Schemenauercf52c072005-08-12 17:34:58 +00001719- Change the %s format specifier for str objects so that it returns a
1720 unicode instance if the argument is not an instance of basestring and
1721 calling __str__ on the argument returns a unicode instance.
1722
Tim Petersf4e69282006-02-27 17:15:31 +00001723- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1724 current thread state when the auto-GIL-state machinery knows about
1725 it (since the thread state is being deleted, continuing to remember it
1726 can't help, but can hurt if another thread happens to get created with
1727 the same thread id).
1728
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001729Extension Modules
1730-----------------
1731
Georg Brandl43f08a82006-03-31 18:01:16 +00001732- Patch #1380952: fix SSL objects timing out on consecutive read()s
1733
Neal Norwitz05a45592006-03-20 06:30:08 +00001734- Patch #1309579: wait3 and wait4 were added to the posix module.
1735
Anthony Baxterfa869072006-03-20 05:21:58 +00001736- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1737 In addition, the existing ulaw code was updated.
1738
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001739- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001740 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001741
Neal Norwitz10be10c2006-03-16 06:50:13 +00001742- Everything under lib-old was removed. This includes the following modules:
1743 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001744 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001745 util, whatsound, whrandom, zmod
1746
1747- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1748
1749- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001750 is deprecated. The undocumented re.engine variable no longer exists.
1751
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001752- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1753 SS2 (single-shift 2) escape sequences correctly.
1754
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001755- The unicodedata module was updated to the 4.1 version of the Unicode
1756 database. The 3.2 version is still available as unicodedata.db_3_2_0
1757 for applications that require this specific version (such as IDNA).
1758
Neal Norwitzb62c4332006-03-04 18:35:47 +00001759- The timing module is no longer built by default. It was deprecated
1760 in PEP 4 in Python 2.0 or earlier.
1761
Guido van Rossum1968ad32006-02-25 22:38:04 +00001762- Patch 1433928: Added a new type, defaultdict, to the collections module.
1763 This uses the new __missing__ hook behavior added to dict (see above).
1764
Georg Brandldbd83392006-02-20 09:42:33 +00001765- Bug #854823: socketmodule now builds on Sun platforms even when
1766 INET_ADDRSTRLEN is not defined.
1767
Georg Brandlf4f44152006-02-18 22:29:33 +00001768- Patch #1393157: os.startfile() now has an optional argument to specify
1769 a "command verb" to invoke on the file.
1770
Neal Norwitz082b2df2006-02-07 07:04:46 +00001771- Bug #876637, prevent stack corruption when socket descriptor
1772 is larger than FD_SETSIZE.

1920 been renamed to have only a single underscore prefix. This was done to
1921 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001922
Nick Coghlan43832302006-04-23 17:04:07 +00001923- PEP 338: new module runpy defines a run_module function to support
1924 executing modules which provide access to source code or a code object
1925 via the PEP 302 import mechanisms.
1926

1935 in attribute values.
1936
Anthony Baxterc51ee692006-04-01 00:57:31 +00001937- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001938 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001939 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001940 module will not be built.
1941
Tim Petersc17976e2006-04-01 00:26:53 +00001942- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1943 aren't officially supported here, and trying to use them will probably
1944 raise an exception some day. But dicts have been allowed, and "mostly
1945 worked", so support for them won't go away without warning.
1946
Georg Brandl338ef7d2006-03-31 18:42:16 +00001947- Bug #1445068: getpass.getpass() can now be given an explicit stream

1965
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001966- email 4.0 package now integrated. This is largely the same as the email 3.0
1967 package that was included in Python 2.3, except that PEP 8 module names are
1968 now used (e.g. mail.message instead of email.Message). The MIME classes
1969 have been moved to a subpackage (e.g. email.mime.text instead of
1970 email.MIMEText). The old names are still supported for now. Several
1971 deprecated Message methods have been removed and lots of bugs have been
1972 fixed. More details can be found in the email package documentation.
1973
Walter Dörwald40108c92006-03-27 08:15:44 +00001974- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1975 (a subclass of tuple) that provides incremental decoders and encoders
1976 (a way to use stateful codecs without the stream API). Python functions
1977 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1978 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1979 have been added.

1982 a ValueError instead of a StopIteration now (like file and cString.String do).

2052
Neal Norwitz338e7862005-12-23 21:27:46 +00002053- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2054 LoadError as documented, instead of IOError. For compatibility,
2055 LoadError subclasses IOError.
2056
Brett Cannon3cbd0382005-12-16 22:49:23 +00002057- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002058 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2059 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2060 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2061 Ronald L. Rivest offered this advice for Python:
2062
2063 "The consensus of researchers in this area (at least as
2064 expressed at the NIST Hash Function Workshop 10/31/05),
2065 is that SHA-256 is a good choice for the time being, but
2066 that research should continue, and other alternatives may
2067 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002068
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002069- Added a subset of Fredrik Lundh's ElementTree package. Available

2122 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002123 correct line numbers for decoding errors in source code.

2147
Georg Brandl9e43acf2005-07-04 17:16:07 +00002148- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2149 as this can cause problems with apps closing all file descriptors.

2162 Bug #1224621.
2163
Raymond Hettinger68c04532005-06-10 11:05:19 +00002164- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002165 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002166 the generate_tokens() function now accepts a callable argument that
2167 terminates by raising StopIteration.
2168
Georg Brandl9166e1a2005-06-04 09:20:03 +00002169- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2173
Skip Montanaro174dd222005-05-14 20:54:16 +00002174- Patch #1120353: The xmlrpclib module provides better, more transparent,

2177 class at all.
2178
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002179- distutils.commands.upload was added to support uploading distribution

2183 them to PyPI.
2184
Raymond Hettinger267b8682005-03-27 10:47:39 +00002185- decimal operator and comparison methods now return NotImplemented
2186 instead of raising a TypeError when interacting with other types. This
2187 allows other classes to implement __radd__ style methods and have them
2188 work as expected.
2189
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002190- Bug #1163325: Decimal infinities failed to hash. Attempting to
2191 hash a NaN raised an InvalidOperation instead of a TypeError.
2192
Tim Petersecc6e6a2005-07-10 22:30:55 +00002193- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2227
Guido van Rossumd0641422005-02-03 15:01:24 +00002228- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2229 disables recursive traversal through instance attributes, which can
2230 be exploited in various ways.
2231
Tim Peterse3547fd2005-12-16 23:13:57 +00002232- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002233 flags on the HTTP listening socket.
2234
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002235- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2236 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2237
Fred Drakefbdeaad2006-07-29 16:56:15 +00002238- Patches #893642, #1039083: add allow_none, encoding arguments to
2239 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002240

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002243- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2244
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002245- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2246
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002247- Enhancements to the csv module:
2248
2249 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002250 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002251 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002252 + Dialect parameter parsing has been re-implemented to improve error
2253 reporting.
2254 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2255 dictates.
2256 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002257 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002258 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002259 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2260 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002261 + reader now allows \r characters to be quoted (previously it only allowed
2262 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002263 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002264 + Dialect classes passed to the module are no longer instantiated by
2265 the module before being parsed (the former validation scheme required
2266 this, but the mechanism was unreliable).
2267 + The dialect registry now contains instances of the internal
2268 C-coded dialect type, rather than references to python objects.
2269 + the internal c-coded dialect type is now immutable.
2270 + register_dialect now accepts the same keyword dialect specifications
2271 as the reader and writer, allowing the user to register dialects
2272 without first creating a dialect class.
2273 + a configurable limit to the size of parsed fields has been added -
2274 previously, an unmatched quote character could result in the entire
2275 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002276 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002277 the parser field size limit (returning the former limit). The initial
2278 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002279 + A line_num attribute has been added to the reader object, which tracks
2280 the number of lines read from the source iterator. This is not
2281 the same as the number of records returned, as records can span
2282 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002283 + reader and writer objects were not being registered with the cyclic-GC.
2284 This has been fixed.
2285
Brett Cannone6539c42005-01-08 02:43:53 +00002286- _DummyThread objects in the threading module now delete self.__block that is
2287 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2288 lock primitives tend to be limited in number and thus should not be wasted on
2289 a _DummyThread object. Fixes bug #1089632.
2290
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002291- The imghdr module now detects Exif files.
2292
Raymond Hettinger6065d322004-12-20 23:51:53 +00002293- StringIO.truncate() now correctly adjusts the size attribute.
2294 (Bug #951915).
2295
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002296- locale.py now uses an updated locale alias table (built using
2297 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2298 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002299 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002300
Raymond Hettinger3557f422004-12-07 12:02:02 +00002301- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2302
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002303- the pickle module no longer accepts the deprecated None option in the
2304 args tuple returned by __reduce__().
2305
Brett Cannon84667c02004-12-07 03:25:18 +00002306- optparse now optionally imports gettext. This allows its use in setup.py.
2307
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002308- the pickle module no longer uses the deprecated bin parameter.
2309
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002310- the shelve module no longer uses the deprecated binary parameter.
2311
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002312- the pstats module no longer uses the deprecated ignore() method.
2313
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002314- the filecmp module no longer uses the deprecated use_statcache argument.
2315
Raymond Hettinger664347b2004-12-04 21:21:53 +00002316- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2317 extended or overridden by subclasses. Formerly, the subclassed method would
2318 be ignored by the rest of the module. (Bug #1078905).
2319
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002320- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002321 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002322
Walter Dörwald36733692004-12-22 12:50:50 +00002323- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2324 once when a size argument is given. This prevents a buffer overflow in the
2325 tokenizer with very long source lines.
2326
Barry Warsaw538561e2006-01-01 21:48:54 +00002327- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2328 immediately after creating the object, without any intervening
2329 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002330
Skip Montanaro05885812005-01-16 20:48:27 +00002331- The reconvert.quote function can now emit triple-quoted strings. The
2332 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002333
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002334- ``UserString.MutableString`` now supports negative indices in
2335 ``__setitem__`` and ``__delitem__``
2336
Greg Ward40407942005-03-05 02:53:17 +00002337- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2338 correctly.
2339
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002340- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2341 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2342 character even if the user has passed a size parameter to get a proper
2343 line ending. Remove the special handling of a "\r\n" that has been split
2344 between two lines.
2345
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002346- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2347 about illegal code points. The codec now supports PEP 293 style error
2348 handlers.
2349
Walter Dörwald78a78b02005-09-01 12:04:29 +00002350- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002351 from the input stream, so that the output is a byte string in the correct
2352 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002353
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002354- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2355 considering it exactly like a '*'.
2356
Walter Dörwald007f8df2005-10-09 19:42:27 +00002357- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2358 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002359
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002360- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2361
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002362- Patch #1413711: Certain patterns of differences were making difflib
2363 touch the recursion limit.
2364
Walter Dörwald58917a62006-03-31 15:26:22 +00002365- Bug #947906: An object oriented interface has been added to the calendar
2366 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002367 called as a script (e.g. via ``python -mcalendar``). Localized month and
2368 weekday names can be ouput (even if an exotic encoding is used) using
2369 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002370
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002371Build
2372-----
2373
Neal Norwitz602d3392006-03-31 08:21:40 +00002374- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2375 by using -mieee gcc option.
2376
Martin v. Löwis86d66262006-02-17 08:40:11 +00002377- Patch #1432345: Make python compile on DragonFly.
2378
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002379- Build support for Win64-AMD64 was added.
2380
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002381- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2382
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002383- Patch #881820: look for openpty and forkpty also in libbsd.
2384
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002385- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2386 The zlib module is now builtin on Windows.
2387
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002388- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2389
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002390- Bug #1189330: configure did not correctly determine the necessary
2391 value of LINKCC if python was built with GCC 4.0.
2392
Trent Mick8321b422005-07-26 02:29:21 +00002393- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2394 vulnerability in zlib 1.2.1 and 1.2.2.
2395
Brett Cannon08cd5982005-04-24 22:26:38 +00002396- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2397 flags that change binary compatibility. Changes were also made to
2398 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002399 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002400
Bob Ippolitoed233462005-03-29 13:47:59 +00002401- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2402 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2403 no longer exists). This configure patch makes things right.
2404
Martin v. Löwise2713be2005-03-08 15:03:08 +00002405- Bug #1158607: Build with --disable-unicode again.
2406
Brett Cannon46d96232005-02-16 00:07:19 +00002407- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2408 defined. Discovered as a result of not being able to build on OS X.
2409
Brett Cannon516592f2004-12-07 00:42:59 +00002410- setup.py now uses the directories specified in LDFLAGS using the -L option
2411 and in CPPFLAGS using the -I option for adding library and include
2412 directories, respectively, for compiling extension modules against. This has
2413 led to the core being compiled using the values in CPPFLAGS. It also removes
2414 the need for the special-casing of both DarwinPorts and Fink for darwin since
2415 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2416 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2417 Fink, ``-I/opt/local/include`` for DarwinPorts).
2418
Brett Cannon43802422005-02-10 20:48:03 +00002419- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2420 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2421 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2422 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002424C API
2425-----
2426
Tim Petersc9d78aa2006-03-26 23:27:58 +00002427- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2428 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2429 is obtained via the ``PyObject_`` family, it must be released via the
2430 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2431 always been officially true, but when Python's small-object allocator was
2432 introduced, an attempt was made to cater to a few extension modules
2433 discovered at the time that obtained memory via ``PyObject_New`` but
2434 released it via ``PyMem_DEL``. It's years later, and if such code still
2435 exists it will fail now (probably with segfaults, but calling wrong
2436 low-level memory management functions can yield many symptoms).
2437
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002438- Added a C API for set and frozenset objects.
2439
Raymond Hettinger66517482004-12-03 11:45:13 +00002440- Removed PyRange_New().
2441
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002442- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2443 mapping argument now. This string is used as a mapping table. Byte values
2444 greater than the length of the string and 0xFFFE are treated as undefined
2445 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002451- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002452
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002453- Patch #1276356: New resource "urlfetch" is implemented. This enables
2454 even impatient people to run tests that require remote files.
