Neal Norwitz0bcafac2006-09-11 08:51:17 +0000365- Make _PyGILState_NoteThreadState() static, it was not used anywhere
366 outside of pystate.c and should not be necessary.
367
Brett Cannon19d76c52006-09-09 07:18:44 +0000368- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
369 allows calling unicode() on exceptions classes directly to succeed.
370
Georg Brandlecab6232006-09-06 06:47:02 +0000371- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

387 head is the original string if sep was not found.
388
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000389- Bug #1520864: unpacking singleton tuples in list comprehensions and
390 generator expressions (x for x, in ... ) works again. Fixing this problem
391 required changing the .pyc magic number. This means that .pyc files
392 generated before 2.5c2 will be regenerated.

495Core and builtins
496-----------------
497
Neal Norwitz24b6f202006-09-05 04:43:56 +0000498- Fix infinite recursion when subclassing long and overriding __hash__.
499
500- Fix concatenation (+=) of long strings.
501
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000502- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000503 compared equal or unequal to a string and a UnicodeDecodeError
504 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000505
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000506 Instead, the equal (==) and unequal (!=) comparison operators will
507 now issue a UnicodeWarning and interpret the two objects as
508 unequal. The UnicodeWarning can be filtered as desired using
509 the warning framework, e.g. silenced completely, turned into an
510 exception, logged, etc.
511
512 Note that compare operators other than equal and unequal will still
513 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000514
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000515- Fix segfault when doing string formatting on subclasses of long.
516
517- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
518 with new-style classes.
519
520- Fix bug related to __len__ functions returning negative values with
521 classic classes.
522
523- Patch #1538606, Fix __index__() clipping. There were some problems
524 discovered with the API and how integers that didn't fit into Py_ssize_t
525 were handled. This patch attempts to provide enough alternatives
526 to effectively use __index__.
527
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000528- Bug #1536021: __hash__ may now return long int; the final hash
529 value is obtained by invoking hash on the long int.
530
Thomas Hellerab1049c2006-08-08 17:37:00 +0000531- Bug #1536786: buffer comparison could emit a RuntimeWarning.

534 sys.stdin is closed.
535
Thomas Heller74d36f02006-08-04 18:17:40 +0000536- On Windows, the PyErr_Warn function is now exported from
537 the Python dll again.
538
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000539- Bug #1191458: tracing over for loops now produces a line event
540 on each iteration. Fixing this problem required changing the .pyc
541 magic number. This means that .pyc files generated before 2.5c1
542 will be regenerated.
543
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000544- Bug #1333982: string/number constants were inappropriately stored
545 in the byte code and co_consts even if they were not used, ie
546 immediately popped off the stack.
547
Georg Brandle9462c72006-08-04 18:03:37 +0000548- Fixed a reference-counting problem in property().

552-------
553
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000554- Fix a bug in the ``compiler`` package that caused invalid code to be
555 generated for generator expressions.
556
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000557- The distutils version has been changed to 2.5.0. The change to
558 keep it programmatically in sync with the Python version running
559 the code (introduced in 2.5b3) has been reverted. It will continue
560 to be maintained manually as static string literal.
561
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000562- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000563 and this cannot be converted to the required C type, an exception is
564 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000565 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000566
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000567- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000568 an exception.
569
Tim Peterscbdd3502006-09-05 01:47:53 +0000570- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000571 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000572 workarounds for clocks with low resolution, to stop the code yielding
573 duplicate UUIDs.
574
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000575- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
576 before raising SystemExit, allowing IDLE to honor quit() and exit().
577
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000578- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000612- Bug #1530559, struct.pack raises TypeError where it used to convert.
613 Passing float arguments to struct.pack when integers are expected
614 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000659What's New in Python 2.5 beta 3?
660================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000661
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000662*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000663
664Core and builtins
665-----------------
666
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000667- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000668 returned a long (see PEP 353).
669
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000670- Bug #1515471: string.replace() accepts character buffers again.
671
Neal Norwitz07aadb12006-07-30 06:55:48 +0000672- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
673 This provides the proper warning for struct.pack().
674 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
675
Neal Norwitz0d62a062006-07-30 06:53:31 +0000676- Patch #1531113: Fix augmented assignment with yield expressions.
677 Also fix a SystemError when trying to assign to yield expressions.
678
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000679- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
680 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
681 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
682 excessive filesystem operations during imports.
683
Tim Petersbc24eee2006-07-27 01:14:53 +0000684- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
685 operations on signed longs that are formally undefined by C.
686 Unfortunately, at least one compiler now cares about that, so complicated
687 the code to make that compiler happy again.
688
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000689- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
690
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000691- Patch #1232023: Stop including current directory in search
692 path on Windows.
693
Neal Norwitze1fdb322006-07-21 05:32:28 +0000694- Fix some potential crashes found with failmalloc.
695
Neal Norwitze7563102006-07-17 01:00:16 +0000696- Fix warnings reported by Klocwork's static analysis tool.
697
Neal Norwitz84be93b2006-07-16 01:50:38 +0000698- Bug #1512814, Fix incorrect lineno's when code within a function
699 had more than 255 blank lines.
700
Georg Brandl9dceedb2006-07-12 15:31:17 +0000701- Patch #1521179: Python now accepts the standard options ``--help`` and
702 ``--version`` as well as ``/?`` on Windows.
703
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000704- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000705 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000706 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000707
Tim Peters112aad32006-07-19 00:03:19 +0000708- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000709 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000710 new ``sys._current_frames()`` returns a dictionary with one entry,
711 mapping the faux "thread id" 0 to the current frame.
712
Ronald Oussoren3075e162006-07-25 20:28:55 +0000713- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000714
Ronald Oussoren3075e162006-07-25 20:28:55 +0000715
Neal Norwitza1f10902006-07-12 07:28:29 +0000716Library
717-------
718
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000719- Correction of patch #1455898: In the mbcs decoder, set final=False
720 for stream decoder, but final=True for the decode function.
721
Georg Brandl07fec3a2006-08-01 18:49:24 +0000722- os.urandom no longer masks unrelated exceptions like SystemExit or
723 KeyboardInterrupt.
724
Tim Peters4643c2f2006-08-10 22:45:34 +0000725- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000726 shutil.copytree on Windows
727
Georg Brandle34ac7c2006-07-30 11:07:23 +0000728- Bug #1002398: The documentation for os.path.sameopenfile now correctly
729 refers to file descriptors, not file objects.
730
Tim Peterscbdd3502006-09-05 01:47:53 +0000731- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000732 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000733 #1513611, and probably others.
734
Georg Brandledd9b0d2006-07-29 09:33:26 +0000735- Bug #1441397: The compiler module now recognizes module and function
736 docstrings correctly as it did in Python 2.4.
737
Tim Peters6f681472006-07-27 23:44:37 +0000738- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
739 lost that tests are sorted by name before being run. This rarely
740 matters for well-written tests, but can create baffling symptoms if
741 side effects from one test to the next affect outcomes. ``DocTestFinder``
742 has been changed to sort the list of tests it returns.
743
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000744- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000745 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000746
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000747- Bug #978833: Really close underlying socket in _socketobject.close.
748
Georg Brandldb232dc2006-08-20 13:15:43 +0000749- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
750 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000751
Georg Brandlcf0c1722006-07-26 07:23:32 +0000752- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
753 to recursive calls and call it with the failing package name.
754
Martin v. Löwis0b483032006-07-25 09:53:12 +0000755- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
756
Georg Brandlc13c34c2006-07-24 14:09:56 +0000757- Patch #1515343: Fix printing of deprecated string exceptions with a
758 value in the traceback module.
759
Greg Ward48fae7a2006-07-23 16:05:51 +0000760- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
761
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000762- Patch #1524429: Use repr() instead of backticks in Tkinter again.
763
Brett Cannoncaebe222006-07-18 04:41:36 +0000764- Bug #1520914: Change time.strftime() to accept a zero for any position in its
765 argument tuple. For arguments where zero is illegal, the value is forced to
766 the minimum value that is correct. This is to support an undocumented but
767 common way people used to fill in inconsequential information in the time
768 tuple pre-2.4.
769
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000770- Patch #1220874: Update the binhex module for Mach-O.
771
Barry Warsawb110bad2006-07-21 14:51:07 +0000772- The email package has improved RFC 2231 support, specifically for
773 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
774 (name*0=<blah>) parameter continuations. This may change the types of
775 values returned from email.message.Message.get_param() and friends.
776 Specifically in some cases where non-encoded continuations were used,
777 get_param() used to return a 3-tuple of (None, None, string) whereas now it
778 will just return the string (since non-encoded continuations don't have
779 charset and language parts).
780
781 Also, whereas % values were decoded in all parameter continuations, they are
782 now only decoded in encoded parameter parts.
783
Ronald Oussoren3075e162006-07-25 20:28:55 +0000784- Bug #1517990: IDLE keybindings on MacOS X now work correctly
785
786- Bug #1517996: IDLE now longer shows the default Tk menu when a
787 path browser, class browser or debugger is the frontmost window on MacOS X
788
Barry Warsaw00decd72006-07-27 23:43:15 +0000789- Patch #1520294: Support for getset and member descriptors in types.py,
790 inspect.py, and pydoc.py. Specifically, this allows for querying the type
791 of an object against these built-in types and more importantly, for getting
792 their docstrings printed in the interactive interpreter's help() function.
793
Ronald Oussoren3075e162006-07-25 20:28:55 +0000794
Neal Norwitza1f10902006-07-12 07:28:29 +0000795Extension Modules
796-----------------
797
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000798- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
799 a socket operation on a socket with a timeout, the exception will be
800 caught correctly. Previously, the exception was not caught.
801
Thomas Heller1393d6a2006-07-28 21:43:20 +0000802- Patch #1529514: The _ctypes extension is now compiled on more
803 openbsd target platforms.
804
Tim Peters9cab5932006-07-28 00:30:00 +0000805- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
806 a memory leak, affecting pickles and deep copies.
807
Tim Petersbc24eee2006-07-27 01:14:53 +0000808- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000809 Paul Eggert.
810
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000811- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
812
Thomas Hellerce049a02006-07-14 17:51:14 +0000813- Patch #1521817: Index range checking on ctypes arrays containing
814 exactly one element enabled again. This allows iterating over these
815 arrays, without the need to check the array size before.
816
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000817- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000818 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000819 /dev/null in certain cases; this is now fixed.
820
Thomas Heller47d7a062006-07-12 08:43:47 +0000821- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
822 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000823
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000824- Because of a misspelled preprocessor symbol, ctypes was always
825 compiled without thread support; this is now fixed.
826
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000827- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
828 methods now allow their database parameter to be None as the
829 sleepycat API allows.
830
Matt Flemingec926502006-07-28 11:27:27 +0000831- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
832 bluetooth API compared with Linux and FreeBSD.
833
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000834Tests
835-----
836
837- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
838 how long the test file should take to play. Now accepts taking 2.93 secs
839 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
840
Georg Brandl4793aa32006-07-28 18:31:39 +0000841- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
842 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
843 run via ``regrtest.py``. Now they do.

848- Bug #1439538: Drop usage of test -e in configure as it is not portable.
849
Ronald Oussoren26cad082006-08-01 21:00:57 +0000850Mac
851---
852
853- PythonLauncher now works correctly when the path to the script contains
854 characters that are treated specially by the shell (such as quotes).
855
856- Bug #1527397: PythonLauncher now launches scripts with the working directory
857 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000858 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000859 expect.

867Core and builtins
868-----------------
869
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000870- Bug #1441486: The literal representation of -(sys.maxint - 1)
871 again evaluates to a int object, not a long.
872
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000873- Bug #1501934: The scope of global variables that are locally assigned
874 using augmented assignment is now correctly determined.
875
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000876- Bug #927248: Recursive method-wrapper objects can now safely
877 be released.
878
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000879- Bug #1417699: Reject locale-specific decimal point in float()
880 and atof().
881
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000882- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
883 omit a default "error" argument for NULL pointer. This allows
884 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000885
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000886- Bug #1519018: 'as' is now validated properly in import statements.
887
Neal Norwitz28746ab2006-07-09 22:14:42 +0000888- On 64 bit systems, int literals that use less than 64 bits are
889 now ints rather than longs.
890
Neal Norwitzed657552006-07-10 00:04:44 +0000891- Bug #1512814, Fix incorrect lineno's when code at module scope
892 started after line 256.
893
Tim Peters32a83612006-07-10 21:08:24 +0000894- New function ``sys._current_frames()`` returns a dict mapping thread
895 id to topmost thread stack frame. This is for expert use, and is
896 especially useful for debugging application deadlocks. The functionality
897 was previously available in Fazal Majid's ``threadframe`` extension
898 module, but it wasn't possible to do this in a wholly threadsafe way from
899 an extension.

Tim Peters32a83612006-07-10 21:08:24 +0000909- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000910 environment variable to be set in order to the SDK environment
911 for finding the compiler, include files, etc.
912
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000913- Bug #1515998: Properly generate logical ids for files in bdist_msi.
914
Nick Coghlan2d792252006-07-06 13:47:18 +0000915- warnings.py now ignores ImportWarning by default
916
Thomas Woutersadd19112006-07-05 11:03:49 +0000917- string.Template() now correctly handles tuple-values. Previously,
918 multi-value tuples would raise an exception and single-value tuples would
919 be treated as the value they contain, instead.
920
Martin v. Löwisede77f52006-07-03 13:01:35 +0000921- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
922 even if some data are received.
923
Martin v. Löwis45482392006-07-03 12:28:58 +0000924- Bug #1267547: Put proper recursive setup.py call into the
925 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000931 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000932
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000933- Bug #1514703: Only setup canvas window in turtle when the canvas
934 is created.
935
Martin v. Löwis7596e832006-07-01 15:33:37 +0000936- Bug #1513223: .close() of a _socketobj now releases the underlying
937 socket again, which then gets closed as it becomes unreferenced.
938
Fred Drake10497c82006-06-29 02:57:48 +0000939- Bug #1504333: Make sgmllib support angle brackets in quoted
940 attribute values.
941
942- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
943 sgmllib ('[' and ']' were not accepted).
944
Georg Brandl1be63af2006-06-28 20:23:25 +0000945- Fix a bug in the turtle module's end_fill function.
946
Brett Cannon53ab5b72006-06-22 16:49:14 +0000947- Bug #1510580: The 'warnings' module improperly required that a Warning
948 category be either a types.ClassType and a subclass of Warning. The proper
949 check is just that it is a subclass with Warning as the documentation states.
950
Georg Brandlad29e632006-06-21 17:45:17 +0000951- The compiler module now correctly compiles the new try-except-finally
952 statement (bug #1509132).
953
Neal Norwitz60373cd2006-06-22 06:30:50 +0000954- The wsgiref package is now installed properly on Unix.
955
Vinay Sajip28e57612006-07-01 10:45:20 +0000956- A bug was fixed in logging.config.fileConfig() which caused a crash on
957 shutdown when fileConfig() was called multiple times.
958
Gerhard Häring762fbd32006-07-02 17:48:30 +0000959- The sqlite3 module did cut off data from the SQLite database at the first
960 null character before sending it to a custom converter. This has been fixed
961 now.
962
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000963Extension Modules
964-----------------
965
Tim Peters112aad32006-07-19 00:03:19 +0000966- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
967 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
968 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000969
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000970- Assigning None to pointer type fields in ctypes structures possible
971 overwrote the wrong fields, this is fixed now.
972
973- Fixed a segfault in _ctypes when ctypes.wintypes were imported
974 on non-Windows platforms.
975
976- Bug #1518190: The ctypes.c_void_p constructor now accepts any
977 integer or long, without range checking.
978
979- Patch #1517790: It is now possible to use custom objects in the ctypes
980 foreign function argtypes sequence as long as they provide a from_param
981 method, no longer is it required that the object is a ctypes type.
982
983- The '_ctypes' extension module now works when Python is configured
984 with the --without-threads option.
985
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000986- Bug #1513646: os.access on Windows now correctly determines write
987 access, again.
988
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000989- Bug #1512695: cPickle.loads could crash if it was interrupted with
990 a KeyboardInterrupt.
991
Neal Norwitza12aa882006-07-06 06:45:08 +0000992- Bug #1296433: parsing XML with a non-default encoding and
993 a CharacterDataHandler could crash the interpreter in pyexpat.
994
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000995- Patch #1516912: improve Modules support for OpenVMS.

998-----
999
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001000- Automate Windows build process for the Win64 SSL module.
1001
Tim Peters32a83612006-07-10 21:08:24 +00001002- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001003 Previously, the slight difference could cause compilation errors of the
1004 'zlib' module on systems with more than one version of zlib.
1005
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001006- The MSI compileall step was fixed to also support a TARGETDIR
1007 with spaces in it.
1008
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001009- Bug #1517388: sqlite3.dll is now installed on Windows independent
1010 of Tcl/Tk.
1011
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001012- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001013 trying to be installed even though it's empty.

1037Core and builtins
1038-----------------
1039
Georg Brandla56b9152006-06-19 06:35:54 +00001040- Patch #1507676: Error messages returned by invalid abstract object operations
1041 (such as iterating over an integer) have been improved and now include the
1042 type of the offending object to help with debugging.
1043
Brett Cannonea3912b2006-06-13 21:46:41 +00001044- Bug #992017: A classic class that defined a __coerce__() method that returned
1045 its arguments swapped would infinitely recurse and segfault the interpreter.
1046
Neal Norwitz909eb122006-06-12 02:13:21 +00001047- Fix the socket tests so they can be run concurrently.
1048
Neal Norwitzb9845e72006-06-12 02:11:18 +00001049- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001050 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001051
Brett Cannon22565aa2006-06-09 22:31:23 +00001052- Bug #532646: object.__call__() will continue looking for the __call__
1053 attribute on objects until one without one is found. This leads to recursion
1054 when you take a class and set its __call__ attribute to an instance of the
1055 class. Originally fixed for classic classes, but this fix is for new-style.
1056 Removes the infinite_rec_3 crasher.
1057
Georg Brandl24250812006-06-09 18:45:48 +00001058- The string and unicode methods startswith() and endswith() now accept
1059 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1060
Brett Cannonde3b0522006-06-08 17:00:45 +00001061- Buffer objects, at the C level, never used the char buffer
1062 implementation even when the char buffer for the wrapped object was
1063 explicitly requested (originally returned the read or write buffer).
1064 Now a TypeError is raised if the char buffer is not present but is
1065 requested.
1066
Georg Brandlddbaa662006-06-04 21:56:52 +00001067- Patch #1346214: Statements like "if 0: suite" are now again optimized
1068 away like they were in Python 2.4.
1069
Georg Brandlb7c8f542006-05-27 12:30:25 +00001070- Builtin exceptions are now full-blown new-style classes instead of
1071 instances pretending to be classes, which speeds up exception handling
1072 by about 80% in comparison to 2.5a2.
1073
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001074- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1075 Unicode 4.1.
1076
Georg Brandlf4ef1162006-05-26 18:03:31 +00001077- Patch #921466: sys.path_importer_cache is now used to cache valid and
1078 invalid file paths for the built-in import machinery which leads to
1079 fewer open calls on startup.
1080
Tim Peters696cf432006-05-24 21:10:40 +00001081- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1082 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1083 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1084 the number of input digits (it was and remains linear-time for bases
1085 2, 4, 8, 16 and 32).
1086
Tim Petersb713ec22006-05-23 18:45:30 +00001087- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1088 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1089 an integer close to ``sys.maxint``. This was repaired by patch
1090 #1335972, which also gives a nice speedup.
1091
Richard Jonescebbefc2006-05-23 18:28:17 +00001092- Patch #1337051: reduced size of frame objects.
1093
1094- PyErr_NewException now accepts a tuple of base classes as its
1095 "base" parameter.
1096
Richard Jones7c88dcc2006-05-23 10:37:38 +00001097- Patch #876206: function call speedup by retaining allocated frame
1098 objects.
1099
Georg Brandl7b90e162006-05-18 07:01:27 +00001100- Bug #1462152: file() now checks more thoroughly for invalid mode
1101 strings and removes a possible "U" before passing the mode to the
1102 C library function.
1103
Neal Norwitz1004a532006-05-15 07:17:23 +00001104- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1105
Neal Norwitz373f0a72006-05-15 07:04:36 +00001106- Bug #1487966: Fix SystemError with conditional expression in assignment
1107
Martin v. Löwis879768d2006-05-11 13:28:43 +00001108- WindowsError now has two error code attributes: errno, which carries
1109 the error values from errno.h, and winerror, which carries the error
1110 values from winerror.h. Previous versions put the winerror.h values
1111 (from GetLastError()) into the errno attribute.
1112
Martin v. Löwis77736712006-05-04 05:51:03 +00001113- Patch #1475845: Raise IndentationError for unexpected indent.
1114
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001115- Patch #1479181: split open() and file() from being aliases for each other.
1116
Tim Peters44bd9862006-06-01 13:49:23 +00001117- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1118 methods were always silently ignored by dictionaries when comparing keys.
1119 They are now passed through (except when using the C API function
1120 ``PyDict_GetItem()``, whose semantics did not change).
1121
1122- Bug #1456209: In some obscure cases it was possible for a class with a
1123 custom ``__eq__()`` method to confuse dict internals when class instances
1124 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1125 No, you don't have any code that did this ;-)

1133
Brett Cannon6ee7d012006-06-08 16:23:04 +00001134- Change binascii.hexlify to accept a read-only buffer instead of only a char
1135 buffer and actually follow its documentation.
1136
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001137- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1138
Nick Coghlanc649ec52006-05-29 12:43:05 +00001139- Patch #1478788 (modified version): The functional extension module has
1140 been renamed to _functools and a functools Python wrapper module added.
1141 This provides a home for additional function related utilities that are
1142 not specifically about functional programming. See PEP 309.
1143
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001144- Patch #1493701: performance enhancements for struct module.

1149 copy() method.
1150
Andrew MacIntyre92913322006-06-13 15:04:24 +00001151- Patch #1454481: thread stack size is now tunable at runtime for thread
1152 enabled builds on Windows and systems with Posix threads support.
1153
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001154- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1155 (up to the system limit of 32K characters).
1156
1157- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1158 As a result, these functions now raise WindowsError instead of OSError.
1159
Tim Peters7a822da2006-05-25 21:50:17 +00001160- ``time.clock()`` on Win64 should use the high-performance Windows
1161 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1162 Windows platforms).
1163
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001164- Calling Tk_Init twice is refused if the first call failed as that
1165 may deadlock.
1166
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001167- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1168 accept it without potentially using an uninitialized pointer.
1169
1170- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1171 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1179
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001180- bsddb: the __len__ method of a DB object has been fixed to return correct
1181 results. It could previously incorrectly return 0 in some cases.
1182 Fixes SF bug 1493322 (pybsddb bug 1184012).
1183
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001184- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1185 aborts the db transaction safely when a modifier callback fails.
1186 Fixes SF python patch/bug #1408584.
1187
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001188- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001189 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001190 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1191 database calls that would previously deadlock. [SF python bug #775414]
1192

1202 functions.
1203
Martin v. Löwis3798da02006-06-17 18:44:27 +00001204- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001206- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001207 Tkinter.BaseWidget.
1208
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001209- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1212 classes.
1213
Georg Brandl83cc0d02006-06-14 08:50:03 +00001214- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1215 mime.types file for determining MIME types.
1216
Georg Brandl2605ca82006-06-14 06:08:31 +00001217- Bug #1339007: Shelf objects now don't raise an exception in their
1218 __del__ method when initialization failed.
1219
Martin v. Löwisd8251432006-06-14 05:21:04 +00001220- Patch #1455898: The MBCS codec now supports the incremental mode for
1221 double-byte encodings.
1222
Tim Peters43898b42006-06-14 04:09:25 +00001223- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1224 guarantee that adjacent triples in the return list always describe
1225 non-adjacent blocks. Previously, a pair of matching blocks could end
1226 up being described by multiple adjacent triples that formed a partition
1227 of the matching pair.
1228
Greg Ward0e0c9f42006-06-11 16:24:11 +00001229- Bug #1498146: fix optparse to handle Unicode strings in option help,
1230 description, and epilog.
1231
Greg Wardd1c797e2006-06-11 14:42:41 +00001232- Bug #1366250: minor optparse documentation error.
1233
Greg Ward7f547402006-06-11 00:40:49 +00001234- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1235 clarify docs.
1236
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001237- The wsgiref package has been added to the standard library.
1238
Nick Coghlan676725d2006-06-08 13:54:49 +00001239- The functions update_wrapper() and wraps() have been added to the functools
1240 module. These make it easier to copy relevant metadata from the original
1241 function when writing wrapper functions.
1242
Tim Petersd6a9eef2006-06-05 01:48:21 +00001243- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1244 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001245
Martin v. Löwis3f767792006-06-04 19:36:28 +00001246- Patch #1359618: Speed up charmap encoder by using a trie structure
1247 for lookup.
1248
Tim Petersd609b1a2006-06-02 23:22:51 +00001249- The functions in the ``pprint`` module now sort dictionaries by key
1250 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1251 if and only if its display required more than one line, although that
1252 wasn't documented. The new behavior increases predictability; e.g.,
1253 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1254
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001255- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1256 (thanks for J. J. Lee).
1257
Georg Brandl2b330372006-05-28 20:23:12 +00001258- Patch #1496206: improve urllib2 handling of passwords with respect to
1259 default HTTP and HTTPS ports.
1260
George Yoshidaf3c65de2006-05-28 16:39:09 +00001261- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1262
Bob Ippolito7298f272006-05-23 18:43:47 +00001263- Patch #1281707: speed up gzip.readline.
1264
Georg Brandlb89316f2006-05-17 15:51:16 +00001265- Patch #1180296: Two new functions were added to the locale module:
1266 format_string() to get the effect of "format % items" but locale-aware,
1267 and currency() to format a monetary number with currency sign.
1268
Georg Brandle3a25832006-05-17 14:56:04 +00001269- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1270 and several features added, such as speed and geometry control.
1271
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001272- Patch #1488881: add support for external file objects in bz2 compressed
1273 tarfiles.
1274
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001275- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1276 stdout arguments, making it possible to redirect input and output
1277 for remote debugging.
1278
1279- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1280 a couple of issues, notably handling of long file names using the
1281 GNU LONGNAME extension.
1282
1283- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1284 new flag when ``name`` is already the name of an option flag.
1285
1286- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1287 package.
1288
1289- Patch #1472854: make the rlcompleter.Completer class usable on non-
1290 UNIX platforms.
1291
1292- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1293
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001294- Bug #1472827: correctly escape newlines and tabs in attribute values in
1295 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001325What's New in Python 2.5 alpha 2?
1326=================================
1327
1328*Release date: 27-APR-2006*
1329
1330Core and builtins
1331-----------------
1332
Thomas Heller1b046642006-04-18 18:51:06 +00001333- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1334 by converting these apis from macros into exported functions again:
1335
1336 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1337 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1338 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1339 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1340 PyRun_String Py_CompileString
1341
Martin v. Löwis45294a92006-04-18 06:24:08 +00001342- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1343
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001344- All uses of PyStructSequence_InitType have been changed to initialize
1345 the type objects only once, even if the interpreter is initialized
1346 multiple times.
1347
Neal Norwitz61546162006-04-14 05:20:28 +00001348- Bug #1454485, array.array('u') could crash the interpreter. This was
1349 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1350 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1351
1352- Py_UNICODE is unsigned. It was always documented as unsigned, but
1353 due to a bug had a signed value in previous versions.
1354
Tim Peters3a5e8b12006-04-11 01:44:07 +00001355- Patch #837242: ``id()`` of any Python object always gives a positive
1356 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1357 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001358 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001359 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001360
Tim Peters3a5e8b12006-04-11 01:44:07 +00001361 def __hash__(self):
1362 return id(self) # WRONG
1363
1364 because a hash result must be a (short) Python int but it was always
1365 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001366 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001367 was always usable as a hash value before this patch. That's no longer
1368 necessarily so.
1369
1370- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001371 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001372 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001373 #1454844)
1374
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001375- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1376 involving generators that have paused outside of any ``try`` or ``with``
1377 blocks. (In 2.5a1, a paused generator that was part of a reference
1378 cycle could not be garbage collected, regardless of whether it was
1379 paused in a ``try`` or ``with`` block.)

1392- Bug #1117761: bsddb.*open() no longer raises an exception when using
1393 the cachesize parameter.
1394
1395- Bug #1149413: bsddb.*open() no longer raises an exception when using
1396 a temporary db (file=None) with the 'n' flag to truncate on open.
1397
1398- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1399 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001400
Armin Rigoa9017c32006-04-19 11:50:27 +00001401- Patch #1062014: AF_UNIX sockets under Linux have a special

1408 of the process using the returncode attribute, instead of
1409 abusing errno.
1410
Tim Peters711bf302006-04-25 03:31:36 +00001411- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1412 a doctest to be skipped (the code is not run, and the expected output
1413 or exception is ignored).
1414
Nick Coghlanda2268f2006-04-24 04:37:15 +00001415- Fixed contextlib.nested to cope with exceptions being raised and
1416 caught inside exit handlers.
1417
Greg Wardab05edc2006-04-23 03:47:58 +00001418- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1419 hex, octal, or binary; add ``append_const`` action; keep going if
1420 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1421 added ``epilog`` for better help generation).
1422
Tim Peters21fbd572006-04-21 21:18:10 +00001423- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1424 called from a thread spawned as a side effect of importing a module.
1425
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001426- The pydoc module now supports documenting packages contained in
1427 .zip or .egg files.
1428
1429- The pkgutil module now has several new utility functions, such
1430 as ``walk_packages()`` to support working with packages that are either
1431 in the filesystem or zip files.
1432
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001433- The mailbox module can now modify and delete messages from
1434 mailboxes, in addition to simply reading them. Thanks to Gregory
1435 K. Johnson for writing the code, and to the 2005 Google Summer of
1436 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001437
Tim Petersc7605f22006-04-17 21:12:33 +00001438- The ``__del__`` method of class ``local`` in module ``_threading_local``
1439 returned before accomplishing any of its intended cleanup.
1440
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001441- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001447- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1448 Windows. Bug #1469163.
1449
Phillip J. Eby47032112006-04-11 01:07:43 +00001450- The warnings, linecache, inspect, traceback, site, and doctest modules
1451 were updated to work correctly with modules imported from zipfiles or
1452 via other PEP 302 __loader__ objects.
1453
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001454- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001467- The Makefile now has a reindent target, which runs reindent.py on
1468 the library.
1469

1475 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001476 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001477 CXX from --with-cxx-main, see description in README.
1478

1482
Tim Peters8931ff12006-05-13 23:28:20 +00001483- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1484 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

1486
Anthony Baxter51bcb682006-04-05 14:51:42 +00001487Tests

1489
Nick Coghlanda2268f2006-04-24 04:37:15 +00001490- test_contextlib now checks contextlib.nested can cope with exceptions
1491 being raised and caught inside exit handlers.
1492
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001493- test_cmd_line now checks operation of the -m and -c command switches
1494
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001495- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1496 it separately and by hand. It also wasn't cleaning up its changes to
1497 the current Decimal context.
1498
Thomas Woutersabd08882006-04-26 15:53:30 +00001499- regrtest.py now has a -M option to run tests that test the new limits of
1500 containers, on 64-bit architectures. Running these tests is only sensible
1501 on 64-bit machines with more than two gigabytes of memory. The argument
1502 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001513- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1514
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001515- PEP 343: Added Context Types section to the library reference
1516 and attempted to bring other PEP 343 related documentation into
1517 line with the implementation and/or python-dev discussions.
1518
Tim Peters8dc73d22006-04-24 02:03:16 +00001519- Bug #1337990: clarified that ``doctest`` does not support examples
1520 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001523What's New in Python 2.5 alpha 1?
1524=================================
1525
Anthony Baxterebed3f62006-04-03 15:03:44 +00001526*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001527
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001528Core and builtins
1529-----------------
1530
Nick Coghlan43832302006-04-23 17:04:07 +00001531- PEP 338: -m command line switch now delegates to runpy.run_module
1532 allowing it to support modules in packages and zipfiles
1533
Martin v. Löwisc661b882006-04-20 04:54:23 +00001534- On Windows, .DLL is not an accepted file name extension for
1535 extension modules anymore; extensions are only found if they
1536 end in .PYD.
1537
Martin v. Löwisea62d252006-04-03 10:56:49 +00001538- Bug #1421664: sys.stderr.encoding is now set to the same value as
1539 sys.stdout.encoding.
1540
Neal Norwitz92e212f2006-04-03 04:48:37 +00001541- __import__ accepts keyword arguments.
1542
Georg Brandlccadf842006-03-31 18:54:53 +00001543- Patch #1460496: round() now accepts keyword arguments.
1544
Anthony Baxter262c00a2006-03-30 10:53:17 +00001545- Fixed bug #1459029 - unicode reprs were double-escaped.
1546
Hye-Shik Changd478f342006-03-23 12:32:36 +00001547- Patch #1396919: The system scope threads are reenabled on FreeBSD
1548 5.4 and later versions.
1549
Neal Norwitze98ccf62006-03-23 05:39:47 +00001550- Bug #1115379: Compiling a Unicode string with an encoding declaration
1551 now gives a SyntaxError.
1552
Georg Brandlabd1ff82006-03-18 07:59:59 +00001553- Previously, Python code had no easy way to access the contents of a
1554 cell object. Now, a ``cell_contents`` attribute has been added
1555 (closes patch #1170323).
1556
Tim Peterscf79aac2006-03-16 01:14:46 +00001557- Patch #1123430: Python's small-object allocator now returns an arena to
1558 the system ``free()`` when all memory within an arena becomes unused
1559 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1560 freed. Some applications will see a drop in virtual memory size now,
1561 especially long-running applications that, from time to time, temporarily
1562 use a large number of small objects. Note that when Python returns an
1563 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001564 platform C library will in turn return that memory to the operating system.
1565 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001566 appears to be effective at least on Microsoft C and gcc-based systems.
1567 Thanks to Evan Jones for hard work and patience.
1568
Georg Brandl533ff6f2006-03-08 18:09:27 +00001569- Patch #1434038: property() now uses the getter's docstring if there is
1570 no "doc" argument given. This makes it possible to legitimately use
1571 property() as a decorator to produce a read-only property.
1572
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001573- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1574 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1575 of requiring an int or long in slicing and a few other contexts, enabling
1576 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1577
Neal Norwitz995acdf2006-03-07 05:01:00 +00001578- Fixed various bugs reported by Coverity's Prevent tool.
1579
Brett Cannonbf364092006-03-01 04:25:17 +00001580- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1581 new exception base class, BaseException, which has a new message attribute.
1582 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1583 Raising a string exception now raises a DeprecationWarning.
1584
Thomas Woutersfb609f42006-02-28 16:37:25 +00001585- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1586 explicitly relative, using 'from .module import name' to mean 'from the same
1587 package as this module is in. Imports without dots still default to the
1588 old relative-then-absolute, unless 'from __future__ import
1589 absolute_import' is used.
1590
Brett Cannona7446e32006-02-27 23:39:10 +00001591- Properly check if 'warnings' raises an exception (usually when a filter set
1592 to "error" is triggered) when raising a warning for raising string
1593 exceptions.
1594
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001595- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001596 The name was removed from Include/code.h.
1597
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001598- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001599
Guido van Rossum1968ad32006-02-25 22:38:04 +00001600- Patch 1433928:
1601 - The copy module now "copies" function objects (as atomic objects).
1602 - dict.__getitem__ now looks for a __missing__ hook before raising
1603 KeyError.
1604
Tim Peters84ef21c2006-02-28 20:39:06 +00001605- PEP 343: with statement implemented. Needs ``from __future__ import
1606 with_statement``. Use of 'with' as a variable will generate a warning.
1607 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001608 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001609 The following objects have __context__ methods:
1610 - The built-in file type.
1611 - The thread.LockType type.
1612 - The following types defined by the threading module:
1613 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1614 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001615
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001616- Fix the encodings package codec search function to only search
1617 inside its own package. Fixes problem reported in patch #1433198.
1618
1619 Note: Codec packages should implement and register their own
1620 codec search function. PEP 100 has the details.
1621
Tim Peters9ea89d22006-06-04 03:26:02 +00001622- PEP 353: Using ``Py_ssize_t`` as the index type.
1623
1624- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1625 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1626 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1627 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1628 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001629
Neal Norwitzfc76d632006-01-10 06:03:13 +00001630- Patch #1400181, fix unicode string formatting to not use the locale.
1631 This is how string objects work. u'%f' could use , instead of .
1632 for the decimal point. Now both strings and unicode always use periods.
1633
Neal Norwitz671b9e32006-01-09 07:07:12 +00001634- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1635 configure would break checking curses.h.
1636
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001637- Bug #959576: The pwd module is now builtin. This allows Python to be
1638 built on UNIX platforms without $HOME set.
1639
Neal Norwitzc10978f2005-12-19 06:07:16 +00001640- Bug #1072182, fix some potential problems if characters are signed.
1641
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001642- Bug #889500, fix line number on SyntaxWarning for global declarations.
1643
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001644- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1645
Neal Norwitze7214a12005-12-18 05:03:17 +00001646- Support for converting hex strings to floats no longer works.
1647 This was not portable. float('0x3') now raises a ValueError.
1648
Barry Warsaw2a38a862005-12-18 01:27:35 +00001649- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001650 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001651 is now displayed in interactive prompt banner.
1652
Georg Brandlfa166682005-12-17 21:45:17 +00001653- Implementation of PEP 341 - Unification of try/except and try/finally.
1654 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001655 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001656
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001657- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1658 now encodes backslash correctly.
1659
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001660- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1661
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001662- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001663 and long longs.
1664
Neal Norwitz67715f02005-11-09 06:59:35 +00001665- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001666 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001667 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001668
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001669- Replaced most Unicode charmap codecs with new ones using the
1670 new Unicode translate string feature in the builtin charmap
1671 codec; the codecs were created from the mapping tables available
1672 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1673 encodings now include a mapping for the Apple logo)
1674
Tim Peterse3547fd2005-12-16 23:13:57 +00001675- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001676
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001677- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001678
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001679- A new AST parser implementation was completed. The abstract
1680 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001681 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001682
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001683- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001684 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1685
Neal Norwitz708e51a2005-10-03 04:48:15 +00001686- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1687
Neal Norwitz11bd1192005-10-03 00:54:56 +00001688- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1689 Provide a warning when a directory is passed on the command line.
1690
Neal Norwitz40d37812005-10-02 01:48:49 +00001691- Fix segfault with invalid coding.
1692
1693- SF bug #772896: unknown encoding results in MemoryError.
1694
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001695- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001696 supported a __len__() method which evaluated to False when the iterator
1697 was empty.
1698
Guido van Rossum630db602005-09-20 18:49:54 +00001699- On 64-bit platforms, when __len__() returns a value that cannot be
1700 represented as a C int, raise OverflowError.
1701
Skip Montanarof8948ca2005-09-19 03:54:46 +00001702- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001703 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001704
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001705- SF bug #893549: parsing keyword arguments was broken with a few format
1706 codes.
1707
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001708- Changes donated by Elemental Security to make it work on AIX 5.3
1709 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1710 bug #105470: test_pwd fails on 64bit system (Opteron).
1711
Guido van Rossum539c6622005-09-14 17:49:54 +00001712- Changes donated by Elemental Security to make it work on HP-UX 11 on
1713 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1714
Georg Brandl4550b8d2005-08-26 06:43:52 +00001715- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001716 (fixes bug #1119418).
1717
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001718- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1719
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001720- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1721 exceptions that cause a function to exit.
1722
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001723- The implementation of set() and frozenset() was revised to use its
1724 own internal data structure. Memory consumption is reduced by 1/3
1725 and there are modest speed-ups as well. The API is unchanged.
1726
Tim Petersde7990b2005-07-17 23:45:23 +00001727- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1728
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001729- SF bug #1229429: PyObject_CallMethod failed to decrement some
1730 reference counts in some error exit cases.
1731
Tim Petersecc6e6a2005-07-10 22:30:55 +00001732- SF bug #1185883: Python's small-object memory allocator took over
1733 a block managed by the platform C library whenever a realloc specified
1734 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001735 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001736 portable way to copy data from the C-managed block into Python's
1737 small-object space without risking a memory fault. Python's small-object
1738 realloc now leaves such blocks under the control of the platform C
1739 realloc.
1740
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001741- SF bug #1232517: An overflow error was not detected properly when
1742 attempting to convert a large float to an int in os.utime().
1743
Raymond Hettinger3296e692005-06-29 23:29:56 +00001744- SF bug #1224347: hex longs now print with lowercase letters just
1745 like their int counterparts.
1746
Michael W. Hudson188d4362005-06-20 16:52:57 +00001747- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1748 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1749 interpreter states; back out that fix and do a better job (see
1750 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1751 for a longer write-up of the problem).
1752
Michael W. Hudsondf888462005-06-03 14:41:55 +00001753- SF patch #1180995: marshal now uses a binary format by default when
1754 serializing floats.
1755
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001756- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1757 the routines that promise to produce IEEE 754 binary representations
1758 of floats now simply copy bytes around.
1759
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001760- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1761 278.
1762
Brett Cannonc3647ac2005-04-26 03:45:26 +00001763- patch #1109424: int, long, float, complex, and unicode now check for the
1764 proper magic slot for type conversions when subclassed. Previously the
1765 magic slot was ignored during conversion. Semantics now match the way
1766 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001767 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001768 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001769 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001770
Barry Warsawc8d907c2005-04-19 23:43:40 +00001771- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1772 NULL, now raise an AttributeError when attempting to set or delete the
1773 attribute. Previously a TypeError was raised, but this was inconsistent
1774 with the equivalent pure-Python implementation.
1775
Michael W. Hudson774479c2005-04-18 08:46:17 +00001776- It is now safe to call PyGILState_Release() before
1777 PyEval_InitThreads() (note that if there is reason to believe there
1778 are multiple threads around you still must call PyEval_InitThreads()

Anthony Baxterc51ee692006-04-01 00:57:31 +00002047- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002048 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002049 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002050 module will not be built.
2051
Tim Petersc17976e2006-04-01 00:26:53 +00002052- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2053 aren't officially supported here, and trying to use them will probably
2054 raise an exception some day. But dicts have been allowed, and "mostly
2055 worked", so support for them won't go away without warning.
2056
Georg Brandl338ef7d2006-03-31 18:42:16 +00002057- Bug #1445068: getpass.getpass() can now be given an explicit stream
2058 argument to specify where to write the prompt.
2059
Georg Brandl22ec80b2006-03-31 18:25:44 +00002060- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2066 key to be used for signing the uploaded code.
2067
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002068- Queue.Queue objects now support .task_done() and .join() methods
2069 to make it easier to monitor when daemon threads have completed
2070 processing all enqueued tasks. Patch #1455676.
2071
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002072- popen2.Popen objects now preserve the command in a .cmd attribute.
2073
Thomas Hellerc61c0492006-03-22 10:09:27 +00002074- Added the ctypes ffi package.
2075
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002076- email 4.0 package now integrated. This is largely the same as the email 3.0
2077 package that was included in Python 2.3, except that PEP 8 module names are
2078 now used (e.g. mail.message instead of email.Message). The MIME classes
2079 have been moved to a subpackage (e.g. email.mime.text instead of
2080 email.MIMEText). The old names are still supported for now. Several
2081 deprecated Message methods have been removed and lots of bugs have been
2082 fixed. More details can be found in the email package documentation.
2083
Walter Dörwald40108c92006-03-27 08:15:44 +00002084- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2085 (a subclass of tuple) that provides incremental decoders and encoders
2086 (a way to use stateful codecs without the stream API). Python functions
2087 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2088 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2089 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002090
Walter Dörwald067db482006-03-15 22:17:27 +00002091- Patch #1359365: Calling next() on a closed StringIO.String object raises
2092 a ValueError instead of a StopIteration now (like file and cString.String do).
2093 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2094 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002095
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002096- A regrtest option -w was added to re-run failed tests in verbose mode.

2102 grew an optional 'generation' argument.
2103
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002104- A library msilib to generate Windows Installer files, and a distutils

2165 LoadError subclasses IOError.
2166

Tim Peterse3547fd2005-12-16 23:13:57 +00002168 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2169 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2170 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2171 Ronald L. Rivest offered this advice for Python:
2172
2173 "The consensus of researchers in this area (at least as
2174 expressed at the NIST Hash Function Workshop 10/31/05),
2175 is that SHA-256 is a good choice for the time being, but
2176 that research should continue, and other alternatives may
2177 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002178
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002179- Added a subset of Fredrik Lundh's ElementTree package. Available

2250 parameter, but uses the usual "kwargs=None".
2251

2273
Raymond Hettinger68c04532005-06-10 11:05:19 +00002274- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002275 roundtrip from lexed tokens back to Python source code. In addition,

2335
Raymond Hettingerbab41432005-02-05 01:31:19 +00002336- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2337
Guido van Rossumd0641422005-02-03 15:01:24 +00002338- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2339 disables recursive traversal through instance attributes, which can
2340 be exploited in various ways.
2341
Tim Peterse3547fd2005-12-16 23:13:57 +00002342- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002343 flags on the HTTP listening socket.
2344
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002345- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2346 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2347
Fred Drakefbdeaad2006-07-29 16:56:15 +00002348- Patches #893642, #1039083: add allow_none, encoding arguments to

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002353- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2354
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002355- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2356
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002357- Enhancements to the csv module:
2358
2359 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002360 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002361 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002362 + Dialect parameter parsing has been re-implemented to improve error
2363 reporting.
2364 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2365 dictates.
2366 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002367 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002368 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002369 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2370 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002371 + reader now allows \r characters to be quoted (previously it only allowed
2372 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002373 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002374 + Dialect classes passed to the module are no longer instantiated by
2375 the module before being parsed (the former validation scheme required
2376 this, but the mechanism was unreliable).
2377 + The dialect registry now contains instances of the internal
2378 C-coded dialect type, rather than references to python objects.
2379 + the internal c-coded dialect type is now immutable.
2380 + register_dialect now accepts the same keyword dialect specifications
2381 as the reader and writer, allowing the user to register dialects
2382 without first creating a dialect class.
2383 + a configurable limit to the size of parsed fields has been added -
2384 previously, an unmatched quote character could result in the entire
2385 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002386 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002387 the parser field size limit (returning the former limit). The initial
2388 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002389 + A line_num attribute has been added to the reader object, which tracks
2390 the number of lines read from the source iterator. This is not
2391 the same as the number of records returned, as records can span
2392 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002393 + reader and writer objects were not being registered with the cyclic-GC.
2394 This has been fixed.
2395
Brett Cannone6539c42005-01-08 02:43:53 +00002396- _DummyThread objects in the threading module now delete self.__block that is
2397 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2398 lock primitives tend to be limited in number and thus should not be wasted on
2399 a _DummyThread object. Fixes bug #1089632.
2400
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002401- The imghdr module now detects Exif files.
2402
Raymond Hettinger6065d322004-12-20 23:51:53 +00002403- StringIO.truncate() now correctly adjusts the size attribute.
2404 (Bug #951915).
2405
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002406- locale.py now uses an updated locale alias table (built using
2407 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2408 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002409 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002410
Raymond Hettinger3557f422004-12-07 12:02:02 +00002411- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2412
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002413- the pickle module no longer accepts the deprecated None option in the
2414 args tuple returned by __reduce__().
2415
Brett Cannon84667c02004-12-07 03:25:18 +00002416- optparse now optionally imports gettext. This allows its use in setup.py.
2417
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002418- the pickle module no longer uses the deprecated bin parameter.
2419
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002420- the shelve module no longer uses the deprecated binary parameter.
2421
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002422- the pstats module no longer uses the deprecated ignore() method.
2423
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002424- the filecmp module no longer uses the deprecated use_statcache argument.
2425
Raymond Hettinger664347b2004-12-04 21:21:53 +00002426- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2427 extended or overridden by subclasses. Formerly, the subclassed method would
2428 be ignored by the rest of the module. (Bug #1078905).
2429
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002430- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002431 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002432
Walter Dörwald36733692004-12-22 12:50:50 +00002433- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2434 once when a size argument is given. This prevents a buffer overflow in the
2435 tokenizer with very long source lines.
2436
Barry Warsaw538561e2006-01-01 21:48:54 +00002437- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2438 immediately after creating the object, without any intervening
2439 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002440
Skip Montanaro05885812005-01-16 20:48:27 +00002441- The reconvert.quote function can now emit triple-quoted strings. The
2442 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002443
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002444- ``UserString.MutableString`` now supports negative indices in
2445 ``__setitem__`` and ``__delitem__``
2446
Greg Ward40407942005-03-05 02:53:17 +00002447- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2448 correctly.
2449
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002450- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2451 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2452 character even if the user has passed a size parameter to get a proper
2453 line ending. Remove the special handling of a "\r\n" that has been split
2454 between two lines.
2455
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002456- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2457 about illegal code points. The codec now supports PEP 293 style error
2458 handlers.
2459
Walter Dörwald78a78b02005-09-01 12:04:29 +00002460- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002461 from the input stream, so that the output is a byte string in the correct
2462 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002463
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002464- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2465 considering it exactly like a '*'.
2466
Walter Dörwald007f8df2005-10-09 19:42:27 +00002467- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2468 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002469
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002470- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2471
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002472- Patch #1413711: Certain patterns of differences were making difflib
2473 touch the recursion limit.
2474
Walter Dörwald58917a62006-03-31 15:26:22 +00002475- Bug #947906: An object oriented interface has been added to the calendar
2476 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002477 called as a script (e.g. via ``python -mcalendar``). Localized month and
2478 weekday names can be ouput (even if an exotic encoding is used) using
2479 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002480
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002481Build
2482-----
2483
Neal Norwitz602d3392006-03-31 08:21:40 +00002484- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2485 by using -mieee gcc option.
2486
Martin v. Löwis86d66262006-02-17 08:40:11 +00002487- Patch #1432345: Make python compile on DragonFly.
2488
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002489- Build support for Win64-AMD64 was added.
2490
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002491- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2492
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002493- Patch #881820: look for openpty and forkpty also in libbsd.
2494
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002495- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2496 The zlib module is now builtin on Windows.
2497
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002498- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2499
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002500- Bug #1189330: configure did not correctly determine the necessary
2501 value of LINKCC if python was built with GCC 4.0.
2502
Trent Mick8321b422005-07-26 02:29:21 +00002503- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2504 vulnerability in zlib 1.2.1 and 1.2.2.
2505
Brett Cannon08cd5982005-04-24 22:26:38 +00002506- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2507 flags that change binary compatibility. Changes were also made to
2508 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002509 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002510
Bob Ippolitoed233462005-03-29 13:47:59 +00002511- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2512 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2513 no longer exists). This configure patch makes things right.
2514
Martin v. Löwise2713be2005-03-08 15:03:08 +00002515- Bug #1158607: Build with --disable-unicode again.
2516
Brett Cannon46d96232005-02-16 00:07:19 +00002517- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2518 defined. Discovered as a result of not being able to build on OS X.
2519
Brett Cannon516592f2004-12-07 00:42:59 +00002520- setup.py now uses the directories specified in LDFLAGS using the -L option
2521 and in CPPFLAGS using the -I option for adding library and include
2522 directories, respectively, for compiling extension modules against. This has
2523 led to the core being compiled using the values in CPPFLAGS. It also removes
2524 the need for the special-casing of both DarwinPorts and Fink for darwin since
2525 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2526 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2527 Fink, ``-I/opt/local/include`` for DarwinPorts).
2528
Brett Cannon43802422005-02-10 20:48:03 +00002529- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2530 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2531 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2532 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002534C API
2535-----
2536
Tim Petersc9d78aa2006-03-26 23:27:58 +00002537- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2538 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2539 is obtained via the ``PyObject_`` family, it must be released via the
2540 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2541 always been officially true, but when Python's small-object allocator was
2542 introduced, an attempt was made to cater to a few extension modules
2543 discovered at the time that obtained memory via ``PyObject_New`` but
2544 released it via ``PyMem_DEL``. It's years later, and if such code still
2545 exists it will fail now (probably with segfaults, but calling wrong
2546 low-level memory management functions can yield many symptoms).
2547
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002548- Added a C API for set and frozenset objects.
2549
Raymond Hettinger66517482004-12-03 11:45:13 +00002550- Removed PyRange_New().
2551
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002552- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2553 mapping argument now. This string is used as a mapping table. Byte values
2554 greater than the length of the string and 0xFFFE are treated as undefined
2555 mappings.
