Neal Norwitz0bcafac2006-09-11 08:51:17 +0000357- Make _PyGILState_NoteThreadState() static, it was not used anywhere
358 outside of pystate.c and should not be necessary.
359
Brett Cannon19d76c52006-09-09 07:18:44 +0000360- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
361 allows calling unicode() on exceptions classes directly to succeed.
362
Georg Brandlecab6232006-09-06 06:47:02 +0000363- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000378- The return tuple from str.rpartition(sep) is (tail, sep, head) where
379 head is the original string if sep was not found.
380
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000381- Bug #1520864: unpacking singleton tuples in list comprehensions and
382 generator expressions (x for x, in ... ) works again. Fixing this problem
383 required changing the .pyc magic number. This means that .pyc files
384 generated before 2.5c2 will be regenerated.

487Core and builtins
488-----------------
489
Neal Norwitz24b6f202006-09-05 04:43:56 +0000490- Fix infinite recursion when subclassing long and overriding __hash__.
491
492- Fix concatenation (+=) of long strings.
493
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000494- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000495 compared equal or unequal to a string and a UnicodeDecodeError
496 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000497
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000498 Instead, the equal (==) and unequal (!=) comparison operators will
499 now issue a UnicodeWarning and interpret the two objects as
500 unequal. The UnicodeWarning can be filtered as desired using
501 the warning framework, e.g. silenced completely, turned into an
502 exception, logged, etc.
503
504 Note that compare operators other than equal and unequal will still
505 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000506
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000507- Fix segfault when doing string formatting on subclasses of long.

511
512- Fix bug related to __len__ functions returning negative values with
513 classic classes.
514
515- Patch #1538606, Fix __index__() clipping. There were some problems
516 discovered with the API and how integers that didn't fit into Py_ssize_t
517 were handled. This patch attempts to provide enough alternatives
518 to effectively use __index__.
519
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000520- Bug #1536021: __hash__ may now return long int; the final hash
521 value is obtained by invoking hash on the long int.
522
Thomas Hellerab1049c2006-08-08 17:37:00 +0000523- Bug #1536786: buffer comparison could emit a RuntimeWarning.

526 sys.stdin is closed.
527
Thomas Heller74d36f02006-08-04 18:17:40 +0000528- On Windows, the PyErr_Warn function is now exported from
529 the Python dll again.
530
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000531- Bug #1191458: tracing over for loops now produces a line event
532 on each iteration. Fixing this problem required changing the .pyc
533 magic number. This means that .pyc files generated before 2.5c1
534 will be regenerated.
535
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000536- Bug #1333982: string/number constants were inappropriately stored
537 in the byte code and co_consts even if they were not used, ie
538 immediately popped off the stack.
539
Georg Brandle9462c72006-08-04 18:03:37 +0000540- Fixed a reference-counting problem in property().

Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000546- Fix a bug in the ``compiler`` package that caused invalid code to be
547 generated for generator expressions.
548
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000549- The distutils version has been changed to 2.5.0. The change to
550 keep it programmatically in sync with the Python version running
551 the code (introduced in 2.5b3) has been reverted. It will continue
552 to be maintained manually as static string literal.
553
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000554- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000555 and this cannot be converted to the required C type, an exception is
556 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000557 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000558
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000559- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000560 an exception.
561
Tim Peterscbdd3502006-09-05 01:47:53 +0000562- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000563 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000564 workarounds for clocks with low resolution, to stop the code yielding
565 duplicate UUIDs.
566
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000567- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
568 before raising SystemExit, allowing IDLE to honor quit() and exit().
569
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000570- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

596
Thomas Heller1ce433e2006-08-14 16:20:04 +0000597- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
598 '-no-stack-protector' compiler flag for OpenBSD has been removed.
599
Thomas Heller86720042006-08-14 11:17:48 +0000600- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now

602 function calls. The ctypes version number was changed to 1.0.1.
603
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000604- Bug #1530559, struct.pack raises TypeError where it used to convert.
605 Passing float arguments to struct.pack when integers are expected
606 now triggers a DeprecationWarning.

Neal Norwitz003c9e22006-08-11 06:09:41 +0000615- test_mailbox should now work on cygwin versions 2006-08-10 and later.
616
Georg Brandl9908d162006-08-06 07:06:33 +0000617- Bug #1535182: really test the xreadlines() method of bz2 objects.
618
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000619- test_threading now skips testing alternate thread stack sizes on
620 platforms that don't support changing thread stack size.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000632- Bug #1535502, build _hashlib on Windows, and use masm assembler
633 code in OpenSSL.
634
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000635- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
636
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000637- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

641-----
642
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000643- New API for Unicode rich comparisons: PyUnicode_RichCompare()
644
Tim Peters4643c2f2006-08-10 22:45:34 +0000645- Bug #1069160. Internal correctness changes were made to
646 ``PyThreadState_SetAsyncExc()``. A test case was added, and
647 the documentation was changed to state that the return value
648 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000651What's New in Python 2.5 beta 3?
652================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000653
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000654*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000655
656Core and builtins
657-----------------
658
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000659- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000660 returned a long (see PEP 353).
661
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000662- Bug #1515471: string.replace() accepts character buffers again.
663
Neal Norwitz07aadb12006-07-30 06:55:48 +0000664- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
665 This provides the proper warning for struct.pack().
666 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
667
Neal Norwitz0d62a062006-07-30 06:53:31 +0000668- Patch #1531113: Fix augmented assignment with yield expressions.
669 Also fix a SystemError when trying to assign to yield expressions.
670
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000671- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
672 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
673 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
674 excessive filesystem operations during imports.
675
Tim Petersbc24eee2006-07-27 01:14:53 +0000676- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
677 operations on signed longs that are formally undefined by C.
678 Unfortunately, at least one compiler now cares about that, so complicated
679 the code to make that compiler happy again.
680
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000681- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
682
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000683- Patch #1232023: Stop including current directory in search
684 path on Windows.
685
Neal Norwitze1fdb322006-07-21 05:32:28 +0000686- Fix some potential crashes found with failmalloc.
687
Neal Norwitze7563102006-07-17 01:00:16 +0000688- Fix warnings reported by Klocwork's static analysis tool.
689
Neal Norwitz84be93b2006-07-16 01:50:38 +0000690- Bug #1512814, Fix incorrect lineno's when code within a function
691 had more than 255 blank lines.
692
Georg Brandl9dceedb2006-07-12 15:31:17 +0000693- Patch #1521179: Python now accepts the standard options ``--help`` and
694 ``--version`` as well as ``/?`` on Windows.
695
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000696- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000697 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000698 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000699
Tim Peters112aad32006-07-19 00:03:19 +0000700- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000701 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000702 new ``sys._current_frames()`` returns a dictionary with one entry,
703 mapping the faux "thread id" 0 to the current frame.
704
Ronald Oussoren3075e162006-07-25 20:28:55 +0000705- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000706
Ronald Oussoren3075e162006-07-25 20:28:55 +0000707
Neal Norwitza1f10902006-07-12 07:28:29 +0000708Library
709-------
710
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000711- Correction of patch #1455898: In the mbcs decoder, set final=False
712 for stream decoder, but final=True for the decode function.
713
Georg Brandl07fec3a2006-08-01 18:49:24 +0000714- os.urandom no longer masks unrelated exceptions like SystemExit or
715 KeyboardInterrupt.
716
Tim Peters4643c2f2006-08-10 22:45:34 +0000717- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000718 shutil.copytree on Windows
719
Georg Brandle34ac7c2006-07-30 11:07:23 +0000720- Bug #1002398: The documentation for os.path.sameopenfile now correctly
721 refers to file descriptors, not file objects.
722
Tim Peterscbdd3502006-09-05 01:47:53 +0000723- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000724 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000725 #1513611, and probably others.
726
Georg Brandledd9b0d2006-07-29 09:33:26 +0000727- Bug #1441397: The compiler module now recognizes module and function
728 docstrings correctly as it did in Python 2.4.
729
Tim Peters6f681472006-07-27 23:44:37 +0000730- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
731 lost that tests are sorted by name before being run. This rarely
732 matters for well-written tests, but can create baffling symptoms if
733 side effects from one test to the next affect outcomes. ``DocTestFinder``
734 has been changed to sort the list of tests it returns.
735
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000736- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000737 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000738
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000739- Bug #978833: Really close underlying socket in _socketobject.close.
740
Georg Brandldb232dc2006-08-20 13:15:43 +0000741- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
742 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000743
Georg Brandlcf0c1722006-07-26 07:23:32 +0000744- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
745 to recursive calls and call it with the failing package name.
746
Martin v. Löwis0b483032006-07-25 09:53:12 +0000747- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
748
Georg Brandlc13c34c2006-07-24 14:09:56 +0000749- Patch #1515343: Fix printing of deprecated string exceptions with a
750 value in the traceback module.
751
Greg Ward48fae7a2006-07-23 16:05:51 +0000752- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
753
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000754- Patch #1524429: Use repr() instead of backticks in Tkinter again.
755
Brett Cannoncaebe222006-07-18 04:41:36 +0000756- Bug #1520914: Change time.strftime() to accept a zero for any position in its
757 argument tuple. For arguments where zero is illegal, the value is forced to
758 the minimum value that is correct. This is to support an undocumented but
759 common way people used to fill in inconsequential information in the time
760 tuple pre-2.4.
761
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000762- Patch #1220874: Update the binhex module for Mach-O.
763
Barry Warsawb110bad2006-07-21 14:51:07 +0000764- The email package has improved RFC 2231 support, specifically for
765 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
766 (name*0=<blah>) parameter continuations. This may change the types of
767 values returned from email.message.Message.get_param() and friends.
768 Specifically in some cases where non-encoded continuations were used,
769 get_param() used to return a 3-tuple of (None, None, string) whereas now it
770 will just return the string (since non-encoded continuations don't have
771 charset and language parts).
772
773 Also, whereas % values were decoded in all parameter continuations, they are
774 now only decoded in encoded parameter parts.
775
Ronald Oussoren3075e162006-07-25 20:28:55 +0000776- Bug #1517990: IDLE keybindings on MacOS X now work correctly
777
778- Bug #1517996: IDLE now longer shows the default Tk menu when a
779 path browser, class browser or debugger is the frontmost window on MacOS X
780
Barry Warsaw00decd72006-07-27 23:43:15 +0000781- Patch #1520294: Support for getset and member descriptors in types.py,
782 inspect.py, and pydoc.py. Specifically, this allows for querying the type
783 of an object against these built-in types and more importantly, for getting
784 their docstrings printed in the interactive interpreter's help() function.
785
Ronald Oussoren3075e162006-07-25 20:28:55 +0000786
Neal Norwitza1f10902006-07-12 07:28:29 +0000787Extension Modules
788-----------------
789
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000790- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
791 a socket operation on a socket with a timeout, the exception will be
792 caught correctly. Previously, the exception was not caught.
793
Thomas Heller1393d6a2006-07-28 21:43:20 +0000794- Patch #1529514: The _ctypes extension is now compiled on more
795 openbsd target platforms.
796
Tim Peters9cab5932006-07-28 00:30:00 +0000797- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
798 a memory leak, affecting pickles and deep copies.
799
Tim Petersbc24eee2006-07-27 01:14:53 +0000800- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000801 Paul Eggert.
802
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000803- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
804
Thomas Hellerce049a02006-07-14 17:51:14 +0000805- Patch #1521817: Index range checking on ctypes arrays containing
806 exactly one element enabled again. This allows iterating over these
807 arrays, without the need to check the array size before.
808
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000809- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000810 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000811 /dev/null in certain cases; this is now fixed.
812
Thomas Heller47d7a062006-07-12 08:43:47 +0000813- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
814 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000815
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000816- Because of a misspelled preprocessor symbol, ctypes was always
817 compiled without thread support; this is now fixed.
818
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000819- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
820 methods now allow their database parameter to be None as the
821 sleepycat API allows.
822
Matt Flemingec926502006-07-28 11:27:27 +0000823- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
824 bluetooth API compared with Linux and FreeBSD.
825
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000826Tests
827-----
828
829- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
830 how long the test file should take to play. Now accepts taking 2.93 secs
831 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
832
Georg Brandl4793aa32006-07-28 18:31:39 +0000833- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
834 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
835 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000836
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000837Build

839
840- Bug #1439538: Drop usage of test -e in configure as it is not portable.
841
Ronald Oussoren26cad082006-08-01 21:00:57 +0000842Mac
843---
844
845- PythonLauncher now works correctly when the path to the script contains
846 characters that are treated specially by the shell (such as quotes).
847
848- Bug #1527397: PythonLauncher now launches scripts with the working directory
849 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000850 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000851 expect.

859Core and builtins
860-----------------
861
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000862- Bug #1441486: The literal representation of -(sys.maxint - 1)
863 again evaluates to a int object, not a long.
864
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000865- Bug #1501934: The scope of global variables that are locally assigned
866 using augmented assignment is now correctly determined.
867
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000868- Bug #927248: Recursive method-wrapper objects can now safely
869 be released.
870
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000871- Bug #1417699: Reject locale-specific decimal point in float()
872 and atof().
873
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000874- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
875 omit a default "error" argument for NULL pointer. This allows
876 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000877
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000878- Bug #1519018: 'as' is now validated properly in import statements.
879
Neal Norwitz28746ab2006-07-09 22:14:42 +0000880- On 64 bit systems, int literals that use less than 64 bits are
881 now ints rather than longs.
882
Neal Norwitzed657552006-07-10 00:04:44 +0000883- Bug #1512814, Fix incorrect lineno's when code at module scope
884 started after line 256.
885
Tim Peters32a83612006-07-10 21:08:24 +0000886- New function ``sys._current_frames()`` returns a dict mapping thread
887 id to topmost thread stack frame. This is for expert use, and is
888 especially useful for debugging application deadlocks. The functionality
889 was previously available in Fazal Majid's ``threadframe`` extension
890 module, but it wasn't possible to do this in a wholly threadsafe way from
891 an extension.

895
Martin v. Löwis77621582006-07-30 13:27:31 +0000896- Bug #1257728: Mention Cygwin in distutils error message about a missing

908
Thomas Woutersadd19112006-07-05 11:03:49 +0000909- string.Template() now correctly handles tuple-values. Previously,
910 multi-value tuples would raise an exception and single-value tuples would
911 be treated as the value they contain, instead.
912
Martin v. Löwisede77f52006-07-03 13:01:35 +0000913- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
914 even if some data are received.
915

926 is created.
927
Martin v. Löwis7596e832006-07-01 15:33:37 +0000928- Bug #1513223: .close() of a _socketobj now releases the underlying
929 socket again, which then gets closed as it becomes unreferenced.
930
Fred Drake10497c82006-06-29 02:57:48 +0000931- Bug #1504333: Make sgmllib support angle brackets in quoted
932 attribute values.
933
934- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
935 sgmllib ('[' and ']' were not accepted).

938
Brett Cannon53ab5b72006-06-22 16:49:14 +0000939- Bug #1510580: The 'warnings' module improperly required that a Warning
940 category be either a types.ClassType and a subclass of Warning. The proper
941 check is just that it is a subclass with Warning as the documentation states.
942
Georg Brandlad29e632006-06-21 17:45:17 +0000943- The compiler module now correctly compiles the new try-except-finally
944 statement (bug #1509132).
945
Neal Norwitz60373cd2006-06-22 06:30:50 +0000946- The wsgiref package is now installed properly on Unix.
947
Vinay Sajip28e57612006-07-01 10:45:20 +0000948- A bug was fixed in logging.config.fileConfig() which caused a crash on
949 shutdown when fileConfig() was called multiple times.
950
Gerhard Häring762fbd32006-07-02 17:48:30 +0000951- The sqlite3 module did cut off data from the SQLite database at the first
952 null character before sending it to a custom converter. This has been fixed
953 now.

956-----------------
957
Tim Peters112aad32006-07-19 00:03:19 +0000958- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
959 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
960 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000961
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000962- Assigning None to pointer type fields in ctypes structures possible
963 overwrote the wrong fields, this is fixed now.
964
965- Fixed a segfault in _ctypes when ctypes.wintypes were imported
966 on non-Windows platforms.
967
968- Bug #1518190: The ctypes.c_void_p constructor now accepts any
969 integer or long, without range checking.
970
971- Patch #1517790: It is now possible to use custom objects in the ctypes
972 foreign function argtypes sequence as long as they provide a from_param
973 method, no longer is it required that the object is a ctypes type.
974
975- The '_ctypes' extension module now works when Python is configured
976 with the --without-threads option.
977
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000978- Bug #1513646: os.access on Windows now correctly determines write
979 access, again.
980
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000981- Bug #1512695: cPickle.loads could crash if it was interrupted with

993
Tim Peters32a83612006-07-10 21:08:24 +0000994- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000995 Previously, the slight difference could cause compilation errors of the
996 'zlib' module on systems with more than one version of zlib.
997
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000998- The MSI compileall step was fixed to also support a TARGETDIR

1029Core and builtins
1030-----------------
1031
Georg Brandla56b9152006-06-19 06:35:54 +00001032- Patch #1507676: Error messages returned by invalid abstract object operations
1033 (such as iterating over an integer) have been improved and now include the
1034 type of the offending object to help with debugging.
1035
Brett Cannonea3912b2006-06-13 21:46:41 +00001036- Bug #992017: A classic class that defined a __coerce__() method that returned
1037 its arguments swapped would infinitely recurse and segfault the interpreter.
1038
Neal Norwitz909eb122006-06-12 02:13:21 +00001039- Fix the socket tests so they can be run concurrently.
1040
Neal Norwitzb9845e72006-06-12 02:11:18 +00001041- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001042 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001043
Brett Cannon22565aa2006-06-09 22:31:23 +00001044- Bug #532646: object.__call__() will continue looking for the __call__
1045 attribute on objects until one without one is found. This leads to recursion
1046 when you take a class and set its __call__ attribute to an instance of the
1047 class. Originally fixed for classic classes, but this fix is for new-style.
1048 Removes the infinite_rec_3 crasher.
1049
Georg Brandl24250812006-06-09 18:45:48 +00001050- The string and unicode methods startswith() and endswith() now accept
1051 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1052
Brett Cannonde3b0522006-06-08 17:00:45 +00001053- Buffer objects, at the C level, never used the char buffer
1054 implementation even when the char buffer for the wrapped object was
1055 explicitly requested (originally returned the read or write buffer).
1056 Now a TypeError is raised if the char buffer is not present but is
1057 requested.
1058
Georg Brandlddbaa662006-06-04 21:56:52 +00001059- Patch #1346214: Statements like "if 0: suite" are now again optimized
1060 away like they were in Python 2.4.
1061
Georg Brandlb7c8f542006-05-27 12:30:25 +00001062- Builtin exceptions are now full-blown new-style classes instead of
1063 instances pretending to be classes, which speeds up exception handling
1064 by about 80% in comparison to 2.5a2.
1065
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001066- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1067 Unicode 4.1.
1068
Georg Brandlf4ef1162006-05-26 18:03:31 +00001069- Patch #921466: sys.path_importer_cache is now used to cache valid and
1070 invalid file paths for the built-in import machinery which leads to
1071 fewer open calls on startup.
1072
Tim Peters696cf432006-05-24 21:10:40 +00001073- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1074 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1075 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1076 the number of input digits (it was and remains linear-time for bases
1077 2, 4, 8, 16 and 32).
1078
Tim Petersb713ec22006-05-23 18:45:30 +00001079- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1080 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1081 an integer close to ``sys.maxint``. This was repaired by patch
1082 #1335972, which also gives a nice speedup.
1083
Richard Jonescebbefc2006-05-23 18:28:17 +00001084- Patch #1337051: reduced size of frame objects.
1085
1086- PyErr_NewException now accepts a tuple of base classes as its
1087 "base" parameter.
1088
Richard Jones7c88dcc2006-05-23 10:37:38 +00001089- Patch #876206: function call speedup by retaining allocated frame
1090 objects.
1091
Georg Brandl7b90e162006-05-18 07:01:27 +00001092- Bug #1462152: file() now checks more thoroughly for invalid mode
1093 strings and removes a possible "U" before passing the mode to the
1094 C library function.
1095
Neal Norwitz1004a532006-05-15 07:17:23 +00001096- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1097
Neal Norwitz373f0a72006-05-15 07:04:36 +00001098- Bug #1487966: Fix SystemError with conditional expression in assignment
1099
Martin v. Löwis879768d2006-05-11 13:28:43 +00001100- WindowsError now has two error code attributes: errno, which carries
1101 the error values from errno.h, and winerror, which carries the error
1102 values from winerror.h. Previous versions put the winerror.h values
1103 (from GetLastError()) into the errno attribute.
1104
Martin v. Löwis77736712006-05-04 05:51:03 +00001105- Patch #1475845: Raise IndentationError for unexpected indent.
1106
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001107- Patch #1479181: split open() and file() from being aliases for each other.
1108
Tim Peters44bd9862006-06-01 13:49:23 +00001109- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1110 methods were always silently ignored by dictionaries when comparing keys.
1111 They are now passed through (except when using the C API function
1112 ``PyDict_GetItem()``, whose semantics did not change).
1113
1114- Bug #1456209: In some obscure cases it was possible for a class with a
1115 custom ``__eq__()`` method to confuse dict internals when class instances
1116 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1117 No, you don't have any code that did this ;-)

1130
Nick Coghlanc649ec52006-05-29 12:43:05 +00001131- Patch #1478788 (modified version): The functional extension module has
1132 been renamed to _functools and a functools Python wrapper module added.
1133 This provides a home for additional function related utilities that are
1134 not specifically about functional programming. See PEP 309.
1135
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001136- Patch #1493701: performance enhancements for struct module.

1144 enabled builds on Windows and systems with Posix threads support.
1145
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001146- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1147 (up to the system limit of 32K characters).
1148
1149- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1150 As a result, these functions now raise WindowsError instead of OSError.
1151
Tim Peters7a822da2006-05-25 21:50:17 +00001152- ``time.clock()`` on Win64 should use the high-performance Windows
1153 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1154 Windows platforms).
1155
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001156- Calling Tk_Init twice is refused if the first call failed as that
1157 may deadlock.
1158
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001159- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1160 accept it without potentially using an uninitialized pointer.
1161
1162- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1163 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1173 results. It could previously incorrectly return 0 in some cases.
1174 Fixes SF bug 1493322 (pybsddb bug 1184012).
1175
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001176- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1178 Fixes SF python patch/bug #1408584.
1179
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001180- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001181 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001182 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1183 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwis92733be2006-06-17 09:25:15 +00001199 Tkinter.BaseWidget.
1200
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001201- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1202
Martin v. Löwis337487e2006-06-17 09:15:14 +00001203- Patch #763580: Add name and value arguments to Tkinter variable
1204 classes.
1205
Georg Brandl83cc0d02006-06-14 08:50:03 +00001206- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1207 mime.types file for determining MIME types.
1208
Georg Brandl2605ca82006-06-14 06:08:31 +00001209- Bug #1339007: Shelf objects now don't raise an exception in their
1210 __del__ method when initialization failed.
1211
Martin v. Löwisd8251432006-06-14 05:21:04 +00001212- Patch #1455898: The MBCS codec now supports the incremental mode for
1213 double-byte encodings.
1214
Tim Peters43898b42006-06-14 04:09:25 +00001215- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1216 guarantee that adjacent triples in the return list always describe
1217 non-adjacent blocks. Previously, a pair of matching blocks could end
1218 up being described by multiple adjacent triples that formed a partition
1219 of the matching pair.
1220
Greg Ward0e0c9f42006-06-11 16:24:11 +00001221- Bug #1498146: fix optparse to handle Unicode strings in option help,
1222 description, and epilog.
1223
Greg Wardd1c797e2006-06-11 14:42:41 +00001224- Bug #1366250: minor optparse documentation error.
1225
Greg Ward7f547402006-06-11 00:40:49 +00001226- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1227 clarify docs.
1228
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001229- The wsgiref package has been added to the standard library.
1230
Nick Coghlan676725d2006-06-08 13:54:49 +00001231- The functions update_wrapper() and wraps() have been added to the functools
1232 module. These make it easier to copy relevant metadata from the original
1233 function when writing wrapper functions.
1234
Tim Petersd6a9eef2006-06-05 01:48:21 +00001235- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1236 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001237
Martin v. Löwis3f767792006-06-04 19:36:28 +00001238- Patch #1359618: Speed up charmap encoder by using a trie structure
1239 for lookup.
1240
Tim Petersd609b1a2006-06-02 23:22:51 +00001241- The functions in the ``pprint`` module now sort dictionaries by key
1242 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1243 if and only if its display required more than one line, although that
1244 wasn't documented. The new behavior increases predictability; e.g.,
1245 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1246
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001247- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1248 (thanks for J. J. Lee).
1249
Georg Brandl2b330372006-05-28 20:23:12 +00001250- Patch #1496206: improve urllib2 handling of passwords with respect to
1251 default HTTP and HTTPS ports.
1252
George Yoshidaf3c65de2006-05-28 16:39:09 +00001253- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1254
Bob Ippolito7298f272006-05-23 18:43:47 +00001255- Patch #1281707: speed up gzip.readline.
1256
Georg Brandlb89316f2006-05-17 15:51:16 +00001257- Patch #1180296: Two new functions were added to the locale module:
1258 format_string() to get the effect of "format % items" but locale-aware,
1259 and currency() to format a monetary number with currency sign.
1260
Georg Brandle3a25832006-05-17 14:56:04 +00001261- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1262 and several features added, such as speed and geometry control.
1263
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001264- Patch #1488881: add support for external file objects in bz2 compressed
1265 tarfiles.
1266
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001267- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1268 stdout arguments, making it possible to redirect input and output
1269 for remote debugging.
1270
1271- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1272 a couple of issues, notably handling of long file names using the
1273 GNU LONGNAME extension.
1274
1275- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1276 new flag when ``name`` is already the name of an option flag.
1277
1278- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1279 package.
1280
1281- Patch #1472854: make the rlcompleter.Completer class usable on non-
1282 UNIX platforms.
1283
1284- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1285
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001286- Bug #1472827: correctly escape newlines and tabs in attribute values in
1287 the saxutils.XMLGenerator class.

1319
1320*Release date: 27-APR-2006*
1321
1322Core and builtins
1323-----------------
1324
Thomas Heller1b046642006-04-18 18:51:06 +00001325- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1326 by converting these apis from macros into exported functions again:
1327
1328 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1329 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1330 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1331 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1332 PyRun_String Py_CompileString
1333
Martin v. Löwis45294a92006-04-18 06:24:08 +00001334- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1335
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001336- All uses of PyStructSequence_InitType have been changed to initialize
1337 the type objects only once, even if the interpreter is initialized
1338 multiple times.
1339
Neal Norwitz61546162006-04-14 05:20:28 +00001340- Bug #1454485, array.array('u') could crash the interpreter. This was
1341 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1342 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1343
1344- Py_UNICODE is unsigned. It was always documented as unsigned, but
1345 due to a bug had a signed value in previous versions.
1346
Tim Peters3a5e8b12006-04-11 01:44:07 +00001347- Patch #837242: ``id()`` of any Python object always gives a positive
1348 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1349 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001350 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001351 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001352
Tim Peters3a5e8b12006-04-11 01:44:07 +00001353 def __hash__(self):
1354 return id(self) # WRONG
1355
1356 because a hash result must be a (short) Python int but it was always
1357 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001358 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001359 was always usable as a hash value before this patch. That's no longer
1360 necessarily so.
1361
1362- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001363 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001364 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001365 #1454844)
1366
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001367- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1368 involving generators that have paused outside of any ``try`` or ``with``
1369 blocks. (In 2.5a1, a paused generator that was part of a reference
1370 cycle could not be garbage collected, regardless of whether it was
1371 paused in a ``try`` or ``with`` block.)

1378
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001379- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1380 fails with an error condition.
1381
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001382- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

1384- Bug #1117761: bsddb.*open() no longer raises an exception when using
1385 the cachesize parameter.
1386
1387- Bug #1149413: bsddb.*open() no longer raises an exception when using
1388 a temporary db (file=None) with the 'n' flag to truncate on open.
1389
1390- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1391 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001392
Armin Rigoa9017c32006-04-19 11:50:27 +00001393- Patch #1062014: AF_UNIX sockets under Linux have a special

1400 of the process using the returncode attribute, instead of
1401 abusing errno.
1402
Tim Peters711bf302006-04-25 03:31:36 +00001403- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1404 a doctest to be skipped (the code is not run, and the expected output
1405 or exception is ignored).
1406
Nick Coghlanda2268f2006-04-24 04:37:15 +00001407- Fixed contextlib.nested to cope with exceptions being raised and
1408 caught inside exit handlers.
1409
Greg Wardab05edc2006-04-23 03:47:58 +00001410- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1411 hex, octal, or binary; add ``append_const`` action; keep going if
1412 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1413 added ``epilog`` for better help generation).
1414
Tim Peters21fbd572006-04-21 21:18:10 +00001415- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1416 called from a thread spawned as a side effect of importing a module.
1417
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001418- The pydoc module now supports documenting packages contained in
1419 .zip or .egg files.
1420
1421- The pkgutil module now has several new utility functions, such
1422 as ``walk_packages()`` to support working with packages that are either
1423 in the filesystem or zip files.
1424
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001425- The mailbox module can now modify and delete messages from
1426 mailboxes, in addition to simply reading them. Thanks to Gregory
1427 K. Johnson for writing the code, and to the 2005 Google Summer of
1428 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001429
Tim Petersc7605f22006-04-17 21:12:33 +00001430- The ``__del__`` method of class ``local`` in module ``_threading_local``
1431 returned before accomplishing any of its intended cleanup.
1432
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001433- Patch #790710: Add breakpoint command lists in pdb.

1438
Anthony Baxtere29002c2006-04-12 12:07:31 +00001439- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1440 Windows. Bug #1469163.
1441
Phillip J. Eby47032112006-04-11 01:07:43 +00001442- The warnings, linecache, inspect, traceback, site, and doctest modules
1443 were updated to work correctly with modules imported from zipfiles or
1444 via other PEP 302 __loader__ objects.
1445
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001446- Patch #1467770: Reduce usage of subprocess._active to processes which

1458
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001459- The Makefile now has a reindent target, which runs reindent.py on
1460 the library.
1461

1467 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001468 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001469 CXX from --with-cxx-main, see description in README.
1470

1474
Tim Peters8931ff12006-05-13 23:28:20 +00001475- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1476 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1477 and "%zu" for unsigned integers of type ``size_t``.
1478
Anthony Baxter51bcb682006-04-05 14:51:42 +00001479Tests
1480-----
1481
Nick Coghlanda2268f2006-04-24 04:37:15 +00001482- test_contextlib now checks contextlib.nested can cope with exceptions
1483 being raised and caught inside exit handlers.
1484
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001485- test_cmd_line now checks operation of the -m and -c command switches
1486
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001487- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1488 it separately and by hand. It also wasn't cleaning up its changes to
1489 the current Decimal context.
1490
Thomas Woutersabd08882006-04-26 15:53:30 +00001491- regrtest.py now has a -M option to run tests that test the new limits of
1492 containers, on 64-bit architectures. Running these tests is only sensible
1493 on 64-bit machines with more than two gigabytes of memory. The argument
1494 passed is the maximum amount of memory for the tests to use.

1504
Tim Petersb06d28c2006-05-12 01:57:59 +00001505- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1506
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001507- PEP 343: Added Context Types section to the library reference
1508 and attempted to bring other PEP 343 related documentation into
1509 line with the implementation and/or python-dev discussions.
1510
Tim Peters8dc73d22006-04-24 02:03:16 +00001511- Bug #1337990: clarified that ``doctest`` does not support examples
1512 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001515What's New in Python 2.5 alpha 1?
1516=================================
1517
Anthony Baxterebed3f62006-04-03 15:03:44 +00001518*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001519
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001520Core and builtins
1521-----------------
1522
Nick Coghlan43832302006-04-23 17:04:07 +00001523- PEP 338: -m command line switch now delegates to runpy.run_module
1524 allowing it to support modules in packages and zipfiles
1525
Martin v. Löwisc661b882006-04-20 04:54:23 +00001526- On Windows, .DLL is not an accepted file name extension for
1527 extension modules anymore; extensions are only found if they
1528 end in .PYD.
1529
Martin v. Löwisea62d252006-04-03 10:56:49 +00001530- Bug #1421664: sys.stderr.encoding is now set to the same value as
1531 sys.stdout.encoding.
1532
Neal Norwitz92e212f2006-04-03 04:48:37 +00001533- __import__ accepts keyword arguments.
1534
Georg Brandlccadf842006-03-31 18:54:53 +00001535- Patch #1460496: round() now accepts keyword arguments.
1536
Anthony Baxter262c00a2006-03-30 10:53:17 +00001537- Fixed bug #1459029 - unicode reprs were double-escaped.
1538
Hye-Shik Changd478f342006-03-23 12:32:36 +00001539- Patch #1396919: The system scope threads are reenabled on FreeBSD
1540 5.4 and later versions.
1541
Neal Norwitze98ccf62006-03-23 05:39:47 +00001542- Bug #1115379: Compiling a Unicode string with an encoding declaration
1543 now gives a SyntaxError.
1544
Georg Brandlabd1ff82006-03-18 07:59:59 +00001545- Previously, Python code had no easy way to access the contents of a
1546 cell object. Now, a ``cell_contents`` attribute has been added
1547 (closes patch #1170323).
1548
Tim Peterscf79aac2006-03-16 01:14:46 +00001549- Patch #1123430: Python's small-object allocator now returns an arena to
1550 the system ``free()`` when all memory within an arena becomes unused
1551 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1552 freed. Some applications will see a drop in virtual memory size now,
1553 especially long-running applications that, from time to time, temporarily
1554 use a large number of small objects. Note that when Python returns an
1555 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001556 platform C library will in turn return that memory to the operating system.
1557 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001558 appears to be effective at least on Microsoft C and gcc-based systems.
1559 Thanks to Evan Jones for hard work and patience.
1560
Georg Brandl533ff6f2006-03-08 18:09:27 +00001561- Patch #1434038: property() now uses the getter's docstring if there is
1562 no "doc" argument given. This makes it possible to legitimately use
1563 property() as a decorator to produce a read-only property.
1564
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001565- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1566 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1567 of requiring an int or long in slicing and a few other contexts, enabling
1568 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1569
Neal Norwitz995acdf2006-03-07 05:01:00 +00001570- Fixed various bugs reported by Coverity's Prevent tool.
1571
Brett Cannonbf364092006-03-01 04:25:17 +00001572- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1573 new exception base class, BaseException, which has a new message attribute.
1574 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1575 Raising a string exception now raises a DeprecationWarning.
1576
Thomas Woutersfb609f42006-02-28 16:37:25 +00001577- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1578 explicitly relative, using 'from .module import name' to mean 'from the same
1579 package as this module is in. Imports without dots still default to the
1580 old relative-then-absolute, unless 'from __future__ import
1581 absolute_import' is used.
1582
Brett Cannona7446e32006-02-27 23:39:10 +00001583- Properly check if 'warnings' raises an exception (usually when a filter set
1584 to "error" is triggered) when raising a warning for raising string
1585 exceptions.
1586
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001587- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001588 The name was removed from Include/code.h.
1589
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001590- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001591
Guido van Rossum1968ad32006-02-25 22:38:04 +00001592- Patch 1433928:
1593 - The copy module now "copies" function objects (as atomic objects).
1594 - dict.__getitem__ now looks for a __missing__ hook before raising
1595 KeyError.
1596
Tim Peters84ef21c2006-02-28 20:39:06 +00001597- PEP 343: with statement implemented. Needs ``from __future__ import
1598 with_statement``. Use of 'with' as a variable will generate a warning.
1599 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001600 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001601 The following objects have __context__ methods:
1602 - The built-in file type.
1603 - The thread.LockType type.
1604 - The following types defined by the threading module:
1605 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1606 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001607
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001608- Fix the encodings package codec search function to only search
1609 inside its own package. Fixes problem reported in patch #1433198.
1610
1611 Note: Codec packages should implement and register their own
1612 codec search function. PEP 100 has the details.
1613
Tim Peters9ea89d22006-06-04 03:26:02 +00001614- PEP 353: Using ``Py_ssize_t`` as the index type.
1615
1616- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1617 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1618 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1619 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1620 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001621
Neal Norwitzfc76d632006-01-10 06:03:13 +00001622- Patch #1400181, fix unicode string formatting to not use the locale.
1623 This is how string objects work. u'%f' could use , instead of .
1624 for the decimal point. Now both strings and unicode always use periods.
1625
Neal Norwitz671b9e32006-01-09 07:07:12 +00001626- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1627 configure would break checking curses.h.
1628
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001629- Bug #959576: The pwd module is now builtin. This allows Python to be
1630 built on UNIX platforms without $HOME set.
1631
Neal Norwitzc10978f2005-12-19 06:07:16 +00001632- Bug #1072182, fix some potential problems if characters are signed.
1633
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001634- Bug #889500, fix line number on SyntaxWarning for global declarations.
1635
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001636- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1637
Neal Norwitze7214a12005-12-18 05:03:17 +00001638- Support for converting hex strings to floats no longer works.
1639 This was not portable. float('0x3') now raises a ValueError.
1640
Barry Warsaw2a38a862005-12-18 01:27:35 +00001641- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001642 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001643 is now displayed in interactive prompt banner.
1644
Georg Brandlfa166682005-12-17 21:45:17 +00001645- Implementation of PEP 341 - Unification of try/except and try/finally.
1646 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001647 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001648
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001649- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1650 now encodes backslash correctly.
1651
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001652- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1653
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001654- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001655 and long longs.
1656
Neal Norwitz67715f02005-11-09 06:59:35 +00001657- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001658 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001659 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001660
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001661- Replaced most Unicode charmap codecs with new ones using the
1662 new Unicode translate string feature in the builtin charmap
1663 codec; the codecs were created from the mapping tables available
1664 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1665 encodings now include a mapping for the Apple logo)
1666
Tim Peterse3547fd2005-12-16 23:13:57 +00001667- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001668
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001669- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001670
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001671- A new AST parser implementation was completed. The abstract
1672 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001673 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001674
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001675- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001676 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1677
Neal Norwitz708e51a2005-10-03 04:48:15 +00001678- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1679
Neal Norwitz11bd1192005-10-03 00:54:56 +00001680- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1681 Provide a warning when a directory is passed on the command line.
1682
Neal Norwitz40d37812005-10-02 01:48:49 +00001683- Fix segfault with invalid coding.
1684
1685- SF bug #772896: unknown encoding results in MemoryError.
1686
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001687- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001688 supported a __len__() method which evaluated to False when the iterator
1689 was empty.
1690
Guido van Rossum630db602005-09-20 18:49:54 +00001691- On 64-bit platforms, when __len__() returns a value that cannot be
1692 represented as a C int, raise OverflowError.
1693
Skip Montanarof8948ca2005-09-19 03:54:46 +00001694- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001695 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001696
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001697- SF bug #893549: parsing keyword arguments was broken with a few format
1698 codes.
1699
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001700- Changes donated by Elemental Security to make it work on AIX 5.3
1701 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1702 bug #105470: test_pwd fails on 64bit system (Opteron).
1703
Guido van Rossum539c6622005-09-14 17:49:54 +00001704- Changes donated by Elemental Security to make it work on HP-UX 11 on
1705 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1706
Georg Brandl4550b8d2005-08-26 06:43:52 +00001707- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001708 (fixes bug #1119418).
1709
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001710- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1711
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001712- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1713 exceptions that cause a function to exit.
1714
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001715- The implementation of set() and frozenset() was revised to use its
1716 own internal data structure. Memory consumption is reduced by 1/3
1717 and there are modest speed-ups as well. The API is unchanged.
1718
Tim Petersde7990b2005-07-17 23:45:23 +00001719- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1720
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001721- SF bug #1229429: PyObject_CallMethod failed to decrement some
1722 reference counts in some error exit cases.
1723
Tim Petersecc6e6a2005-07-10 22:30:55 +00001724- SF bug #1185883: Python's small-object memory allocator took over
1725 a block managed by the platform C library whenever a realloc specified
1726 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001727 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001728 portable way to copy data from the C-managed block into Python's
1729 small-object space without risking a memory fault. Python's small-object
1730 realloc now leaves such blocks under the control of the platform C
1731 realloc.
1732
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001733- SF bug #1232517: An overflow error was not detected properly when
1734 attempting to convert a large float to an int in os.utime().
1735
Raymond Hettinger3296e692005-06-29 23:29:56 +00001736- SF bug #1224347: hex longs now print with lowercase letters just
1737 like their int counterparts.
1738
Michael W. Hudson188d4362005-06-20 16:52:57 +00001739- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1740 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1741 interpreter states; back out that fix and do a better job (see
1742 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1743 for a longer write-up of the problem).
1744
Michael W. Hudsondf888462005-06-03 14:41:55 +00001745- SF patch #1180995: marshal now uses a binary format by default when
1746 serializing floats.
1747
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001748- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1749 the routines that promise to produce IEEE 754 binary representations
1750 of floats now simply copy bytes around.
1751
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001752- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1753 278.
1754
Brett Cannonc3647ac2005-04-26 03:45:26 +00001755- patch #1109424: int, long, float, complex, and unicode now check for the
1756 proper magic slot for type conversions when subclassed. Previously the
1757 magic slot was ignored during conversion. Semantics now match the way
1758 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001759 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001760 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001761 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001762
Barry Warsawc8d907c2005-04-19 23:43:40 +00001763- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1764 NULL, now raise an AttributeError when attempting to set or delete the
1765 attribute. Previously a TypeError was raised, but this was inconsistent
1766 with the equivalent pure-Python implementation.
1767
Michael W. Hudson774479c2005-04-18 08:46:17 +00001768- It is now safe to call PyGILState_Release() before
1769 PyEval_InitThreads() (note that if there is reason to believe there
1770 are multiple threads around you still must call PyEval_InitThreads()
1771 before using the Python API; this fix is for extension modules that
1772 have no way of knowing if Python is multi-threaded yet).
1773
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001774- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1775 disabled caused a crash.

1829 the same thread id).

Tim Peters3a5e8b12006-04-11 01:44:07 +00002041 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002042 module will not be built.
2043
Tim Petersc17976e2006-04-01 00:26:53 +00002044- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2045 aren't officially supported here, and trying to use them will probably
2046 raise an exception some day. But dicts have been allowed, and "mostly
2047 worked", so support for them won't go away without warning.
2048
Georg Brandl338ef7d2006-03-31 18:42:16 +00002049- Bug #1445068: getpass.getpass() can now be given an explicit stream
2050 argument to specify where to write the prompt.
2051
Georg Brandl22ec80b2006-03-31 18:25:44 +00002052- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2058 key to be used for signing the uploaded code.
2059
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002060- Queue.Queue objects now support .task_done() and .join() methods
2061 to make it easier to monitor when daemon threads have completed
2062 processing all enqueued tasks. Patch #1455676.
2063
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002064- popen2.Popen objects now preserve the command in a .cmd attribute.
2065
Thomas Hellerc61c0492006-03-22 10:09:27 +00002066- Added the ctypes ffi package.
2067
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002068- email 4.0 package now integrated. This is largely the same as the email 3.0
2069 package that was included in Python 2.3, except that PEP 8 module names are
2070 now used (e.g. mail.message instead of email.Message). The MIME classes
2071 have been moved to a subpackage (e.g. email.mime.text instead of
2072 email.MIMEText). The old names are still supported for now. Several
2073 deprecated Message methods have been removed and lots of bugs have been
2074 fixed. More details can be found in the email package documentation.
2075
Walter Dörwald40108c92006-03-27 08:15:44 +00002076- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2077 (a subclass of tuple) that provides incremental decoders and encoders
2078 (a way to use stateful codecs without the stream API). Python functions
2079 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2080 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2081 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002082
Walter Dörwald067db482006-03-15 22:17:27 +00002083- Patch #1359365: Calling next() on a closed StringIO.String object raises
2084 a ValueError instead of a StopIteration now (like file and cString.String do).
2085 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2086 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002087
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002088- A regrtest option -w was added to re-run failed tests in verbose mode.

2094 grew an optional 'generation' argument.
2095
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002096- A library msilib to generate Windows Installer files, and a distutils

Tim Peterse3547fd2005-12-16 23:13:57 +00002160 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2161 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2162 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2163 Ronald L. Rivest offered this advice for Python:
2164
2165 "The consensus of researchers in this area (at least as
2166 expressed at the NIST Hash Function Workshop 10/31/05),
2167 is that SHA-256 is a good choice for the time being, but
2168 that research should continue, and other alternatives may
2169 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002170
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002171- Added a subset of Fredrik Lundh's ElementTree package. Available

2242 parameter, but uses the usual "kwargs=None".
2243

2327
Raymond Hettingerbab41432005-02-05 01:31:19 +00002328- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2329
Guido van Rossumd0641422005-02-03 15:01:24 +00002330- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2331 disables recursive traversal through instance attributes, which can
2332 be exploited in various ways.
2333
Tim Peterse3547fd2005-12-16 23:13:57 +00002334- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002335 flags on the HTTP listening socket.
2336
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002337- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2338 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2339
Fred Drakefbdeaad2006-07-29 16:56:15 +00002340- Patches #893642, #1039083: add allow_none, encoding arguments to
2341 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002342

2344
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002345- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2346
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002347- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2348
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002349- Enhancements to the csv module:
2350
2351 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002352 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002353 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002354 + Dialect parameter parsing has been re-implemented to improve error
2355 reporting.
2356 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2357 dictates.
2358 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002359 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002360 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002361 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2362 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002363 + reader now allows \r characters to be quoted (previously it only allowed
2364 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002365 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002366 + Dialect classes passed to the module are no longer instantiated by
2367 the module before being parsed (the former validation scheme required
2368 this, but the mechanism was unreliable).
2369 + The dialect registry now contains instances of the internal
2370 C-coded dialect type, rather than references to python objects.
2371 + the internal c-coded dialect type is now immutable.
2372 + register_dialect now accepts the same keyword dialect specifications
2373 as the reader and writer, allowing the user to register dialects
2374 without first creating a dialect class.
2375 + a configurable limit to the size of parsed fields has been added -
2376 previously, an unmatched quote character could result in the entire
2377 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002378 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002379 the parser field size limit (returning the former limit). The initial
2380 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002381 + A line_num attribute has been added to the reader object, which tracks
2382 the number of lines read from the source iterator. This is not
2383 the same as the number of records returned, as records can span
2384 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002385 + reader and writer objects were not being registered with the cyclic-GC.
2386 This has been fixed.
2387
Brett Cannone6539c42005-01-08 02:43:53 +00002388- _DummyThread objects in the threading module now delete self.__block that is
2389 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2390 lock primitives tend to be limited in number and thus should not be wasted on
2391 a _DummyThread object. Fixes bug #1089632.
2392
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002393- The imghdr module now detects Exif files.
2394
Raymond Hettinger6065d322004-12-20 23:51:53 +00002395- StringIO.truncate() now correctly adjusts the size attribute.
2396 (Bug #951915).
2397
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002398- locale.py now uses an updated locale alias table (built using
2399 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2400 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002401 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002402
Raymond Hettinger3557f422004-12-07 12:02:02 +00002403- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2404
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002405- the pickle module no longer accepts the deprecated None option in the
2406 args tuple returned by __reduce__().
2407
Brett Cannon84667c02004-12-07 03:25:18 +00002408- optparse now optionally imports gettext. This allows its use in setup.py.
2409
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002410- the pickle module no longer uses the deprecated bin parameter.
2411
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002412- the shelve module no longer uses the deprecated binary parameter.
2413
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002414- the pstats module no longer uses the deprecated ignore() method.
2415
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002416- the filecmp module no longer uses the deprecated use_statcache argument.
2417
Raymond Hettinger664347b2004-12-04 21:21:53 +00002418- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2419 extended or overridden by subclasses. Formerly, the subclassed method would
2420 be ignored by the rest of the module. (Bug #1078905).
2421
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002422- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002423 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002424
Walter Dörwald36733692004-12-22 12:50:50 +00002425- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2426 once when a size argument is given. This prevents a buffer overflow in the
2427 tokenizer with very long source lines.
2428
Barry Warsaw538561e2006-01-01 21:48:54 +00002429- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2430 immediately after creating the object, without any intervening
2431 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002432
Skip Montanaro05885812005-01-16 20:48:27 +00002433- The reconvert.quote function can now emit triple-quoted strings. The
2434 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002435
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002436- ``UserString.MutableString`` now supports negative indices in
2437 ``__setitem__`` and ``__delitem__``
2438
Greg Ward40407942005-03-05 02:53:17 +00002439- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2440 correctly.
2441
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002442- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2443 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2444 character even if the user has passed a size parameter to get a proper
2445 line ending. Remove the special handling of a "\r\n" that has been split
2446 between two lines.
2447
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002448- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2449 about illegal code points. The codec now supports PEP 293 style error
2450 handlers.
2451
Walter Dörwald78a78b02005-09-01 12:04:29 +00002452- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002453 from the input stream, so that the output is a byte string in the correct
2454 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002455
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002456- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2457 considering it exactly like a '*'.
2458
Walter Dörwald007f8df2005-10-09 19:42:27 +00002459- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2460 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002461
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002462- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2463
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002464- Patch #1413711: Certain patterns of differences were making difflib
2465 touch the recursion limit.
2466
Walter Dörwald58917a62006-03-31 15:26:22 +00002467- Bug #947906: An object oriented interface has been added to the calendar
2468 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002469 called as a script (e.g. via ``python -mcalendar``). Localized month and
2470 weekday names can be ouput (even if an exotic encoding is used) using
2471 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002472
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002473Build
2474-----
2475
Neal Norwitz602d3392006-03-31 08:21:40 +00002476- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2477 by using -mieee gcc option.
2478
Martin v. Löwis86d66262006-02-17 08:40:11 +00002479- Patch #1432345: Make python compile on DragonFly.
2480
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002481- Build support for Win64-AMD64 was added.
2482
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002483- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2484
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002485- Patch #881820: look for openpty and forkpty also in libbsd.
2486
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002487- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2488 The zlib module is now builtin on Windows.
2489
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002490- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2491
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002492- Bug #1189330: configure did not correctly determine the necessary
2493 value of LINKCC if python was built with GCC 4.0.
2494
Trent Mick8321b422005-07-26 02:29:21 +00002495- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2496 vulnerability in zlib 1.2.1 and 1.2.2.
2497
Brett Cannon08cd5982005-04-24 22:26:38 +00002498- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2499 flags that change binary compatibility. Changes were also made to
2500 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002501 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002502
Bob Ippolitoed233462005-03-29 13:47:59 +00002503- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2504 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2505 no longer exists). This configure patch makes things right.
2506
Martin v. Löwise2713be2005-03-08 15:03:08 +00002507- Bug #1158607: Build with --disable-unicode again.
2508
Brett Cannon46d96232005-02-16 00:07:19 +00002509- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2510 defined. Discovered as a result of not being able to build on OS X.
2511
Brett Cannon516592f2004-12-07 00:42:59 +00002512- setup.py now uses the directories specified in LDFLAGS using the -L option
2513 and in CPPFLAGS using the -I option for adding library and include
2514 directories, respectively, for compiling extension modules against. This has
2515 led to the core being compiled using the values in CPPFLAGS. It also removes
2516 the need for the special-casing of both DarwinPorts and Fink for darwin since
2517 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2518 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2519 Fink, ``-I/opt/local/include`` for DarwinPorts).
2520
Brett Cannon43802422005-02-10 20:48:03 +00002521- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2522 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2523 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2524 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002526C API
2527-----
2528
Tim Petersc9d78aa2006-03-26 23:27:58 +00002529- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2530 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2531 is obtained via the ``PyObject_`` family, it must be released via the
2532 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2533 always been officially true, but when Python's small-object allocator was
2534 introduced, an attempt was made to cater to a few extension modules
2535 discovered at the time that obtained memory via ``PyObject_New`` but
2536 released it via ``PyMem_DEL``. It's years later, and if such code still
2537 exists it will fail now (probably with segfaults, but calling wrong
2538 low-level memory management functions can yield many symptoms).
2539
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002540- Added a C API for set and frozenset objects.
2541
Raymond Hettinger66517482004-12-03 11:45:13 +00002542- Removed PyRange_New().
2543
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002544- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2545 mapping argument now. This string is used as a mapping table. Byte values
2546 greater than the length of the string and 0xFFFE are treated as undefined
2547 mappings.
