Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000336- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
337 mode by only placing a timeout on the select() if an input hook has
338 been defined. This prevents an interactive Python from waking up 10
339 times per second. Patch by Richard Boulton.

Brett Cannon92d54d52007-01-04 00:23:49 +0000347- Added test.test_support.EnvironmentVarGuard. It's a class that provides a
348 context manager so that one can temporarily set or unset environment
349 variables.
350
Brett Cannon6d9520c2006-12-13 23:09:53 +0000351- Added guard_warnings_filter to test.test_support. It returns a context
352 manager that protects the 'warnings' module's filter from being mutated
353 once the context has been exited.
354
Thomas Heller112d1a62006-10-27 19:05:53 +0000355- Added some tests for modulefinder.

437Core and builtins
438-----------------
439
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000440- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000441 compared equal or unequal to a string and a UnicodeDecodeError
442 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000443
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000444 Instead, the equal (==) and unequal (!=) comparison operators will
445 now issue a UnicodeWarning and interpret the two objects as
446 unequal. The UnicodeWarning can be filtered as desired using
447 the warning framework, e.g. silenced completely, turned into an
448 exception, logged, etc.
449
450 Note that compare operators other than equal and unequal will still
451 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000452
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000453- Fix segfault when doing string formatting on subclasses of long.
454
455- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
456 with new-style classes.
457
458- Fix bug related to __len__ functions returning negative values with
459 classic classes.
460
461- Patch #1538606, Fix __index__() clipping. There were some problems
462 discovered with the API and how integers that didn't fit into Py_ssize_t
463 were handled. This patch attempts to provide enough alternatives
464 to effectively use __index__.
465
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000466- Bug #1536021: __hash__ may now return long int; the final hash
467 value is obtained by invoking hash on the long int.
468
Thomas Hellerab1049c2006-08-08 17:37:00 +0000469- Bug #1536786: buffer comparison could emit a RuntimeWarning.
470
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000471- Bug #1535165: fixed a segfault in input() and raw_input() when
472 sys.stdin is closed.
473
Thomas Heller74d36f02006-08-04 18:17:40 +0000474- On Windows, the PyErr_Warn function is now exported from
475 the Python dll again.
476
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000477- Bug #1191458: tracing over for loops now produces a line event
478 on each iteration. Fixing this problem required changing the .pyc
479 magic number. This means that .pyc files generated before 2.5c1
480 will be regenerated.
481
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000482- Bug #1333982: string/number constants were inappropriately stored
483 in the byte code and co_consts even if they were not used, ie
484 immediately popped off the stack.
485
Georg Brandle9462c72006-08-04 18:03:37 +0000486- Fixed a reference-counting problem in property().

489Library
490-------
491
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000492- Fix a bug in the ``compiler`` package that caused invalid code to be
493 generated for generator expressions.
494
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000495- The distutils version has been changed to 2.5.0. The change to
496 keep it programmatically in sync with the Python version running
497 the code (introduced in 2.5b3) has been reverted. It will continue
498 to be maintained manually as static string literal.
499
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000500- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000501 and this cannot be converted to the required C type, an exception is
502 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000503 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000504
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000505- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000506 an exception.
507
Tim Petersc10c9d02006-09-05 02:18:09 +0000508- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000509 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000510 workarounds for clocks with low resolution, to stop the code yielding
511 duplicate UUIDs.
512
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000513- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
514 before raising SystemExit, allowing IDLE to honor quit() and exit().
515
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000516- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
517
Georg Brandl7a1af772006-08-14 21:55:28 +0000518- Patch #1536071: trace.py should now find the full module name of a
519 file correctly even on Windows.
520
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000521- logging's atexit hook now runs even if the rest of the module has
522 already been cleaned up.
523
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000524- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000525
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000526- Bug #1531405, format_exception no longer raises an exception if
527 str(exception) raised an exception.
528
Neil Schemenauer06ded092006-08-04 16:20:30 +0000529- Fix a bug in the ``compiler`` package that caused invalid code to be
530 generated for nested functions.

542 '-no-stack-protector' compiler flag for OpenBSD has been removed.
543
Thomas Heller86720042006-08-14 11:17:48 +0000544- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
545 uses the _as_parameter_ attribute when objects are passed to foreign
546 function calls. The ctypes version number was changed to 1.0.1.
547
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000548- Bug #1530559, struct.pack raises TypeError where it used to convert.

550 now triggers a DeprecationWarning.

609 This provides the proper warning for struct.pack().
610 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
611
Neal Norwitz0d62a062006-07-30 06:53:31 +0000612- Patch #1531113: Fix augmented assignment with yield expressions.
613 Also fix a SystemError when trying to assign to yield expressions.
614
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000615- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
616 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
617 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
618 excessive filesystem operations during imports.
619
Tim Petersbc24eee2006-07-27 01:14:53 +0000620- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
621 operations on signed longs that are formally undefined by C.
622 Unfortunately, at least one compiler now cares about that, so complicated
623 the code to make that compiler happy again.
624
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000625- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
626
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000627- Patch #1232023: Stop including current directory in search
628 path on Windows.

631
Neal Norwitze7563102006-07-17 01:00:16 +0000632- Fix warnings reported by Klocwork's static analysis tool.
633
Neal Norwitz84be93b2006-07-16 01:50:38 +0000634- Bug #1512814, Fix incorrect lineno's when code within a function
635 had more than 255 blank lines.
636
Georg Brandl9dceedb2006-07-12 15:31:17 +0000637- Patch #1521179: Python now accepts the standard options ``--help`` and
638 ``--version`` as well as ``/?`` on Windows.
639
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000640- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000641 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000642 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000643
Tim Peters112aad32006-07-19 00:03:19 +0000644- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000645 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000646 new ``sys._current_frames()`` returns a dictionary with one entry,
647 mapping the faux "thread id" 0 to the current frame.
648
Ronald Oussoren3075e162006-07-25 20:28:55 +0000649- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

653-------
654
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000655- Correction of patch #1455898: In the mbcs decoder, set final=False
656 for stream decoder, but final=True for the decode function.
657
Georg Brandl07fec3a2006-08-01 18:49:24 +0000658- os.urandom no longer masks unrelated exceptions like SystemExit or
659 KeyboardInterrupt.
660
Tim Peters4643c2f2006-08-10 22:45:34 +0000661- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000662 shutil.copytree on Windows
663
Georg Brandle34ac7c2006-07-30 11:07:23 +0000664- Bug #1002398: The documentation for os.path.sameopenfile now correctly
665 refers to file descriptors, not file objects.
666
Tim Petersc10c9d02006-09-05 02:18:09 +0000667- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000668 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000669 #1513611, and probably others.
670
Georg Brandledd9b0d2006-07-29 09:33:26 +0000671- Bug #1441397: The compiler module now recognizes module and function
672 docstrings correctly as it did in Python 2.4.
673
Tim Peters6f681472006-07-27 23:44:37 +0000674- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
675 lost that tests are sorted by name before being run. This rarely
676 matters for well-written tests, but can create baffling symptoms if
677 side effects from one test to the next affect outcomes. ``DocTestFinder``
678 has been changed to sort the list of tests it returns.
679
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000680- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000681 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000682
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000683- Bug #978833: Really close underlying socket in _socketobject.close.

Georg Brandl8c036cc2006-08-20 13:15:39 +0000685- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
686 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000687
Georg Brandlcf0c1722006-07-26 07:23:32 +0000688- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
689 to recursive calls and call it with the failing package name.
690
Martin v. Löwis0b483032006-07-25 09:53:12 +0000691- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
692
Georg Brandlc13c34c2006-07-24 14:09:56 +0000693- Patch #1515343: Fix printing of deprecated string exceptions with a
694 value in the traceback module.
695
Greg Ward48fae7a2006-07-23 16:05:51 +0000696- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
697
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000698- Patch #1524429: Use repr() instead of backticks in Tkinter again.
699
Brett Cannoncaebe222006-07-18 04:41:36 +0000700- Bug #1520914: Change time.strftime() to accept a zero for any position in its
701 argument tuple. For arguments where zero is illegal, the value is forced to
702 the minimum value that is correct. This is to support an undocumented but
703 common way people used to fill in inconsequential information in the time
704 tuple pre-2.4.
705
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000706- Patch #1220874: Update the binhex module for Mach-O.
707
Barry Warsawb110bad2006-07-21 14:51:07 +0000708- The email package has improved RFC 2231 support, specifically for
709 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
710 (name*0=<blah>) parameter continuations. This may change the types of
711 values returned from email.message.Message.get_param() and friends.
712 Specifically in some cases where non-encoded continuations were used,
713 get_param() used to return a 3-tuple of (None, None, string) whereas now it
714 will just return the string (since non-encoded continuations don't have
715 charset and language parts).
716
717 Also, whereas % values were decoded in all parameter continuations, they are
718 now only decoded in encoded parameter parts.
719
Ronald Oussoren3075e162006-07-25 20:28:55 +0000720- Bug #1517990: IDLE keybindings on MacOS X now work correctly
721
722- Bug #1517996: IDLE now longer shows the default Tk menu when a
723 path browser, class browser or debugger is the frontmost window on MacOS X
724
Barry Warsaw00decd72006-07-27 23:43:15 +0000725- Patch #1520294: Support for getset and member descriptors in types.py,
726 inspect.py, and pydoc.py. Specifically, this allows for querying the type
727 of an object against these built-in types and more importantly, for getting
728 their docstrings printed in the interactive interpreter's help() function.

732-----------------
733
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000734- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
735 a socket operation on a socket with a timeout, the exception will be
736 caught correctly. Previously, the exception was not caught.
737
Thomas Heller1393d6a2006-07-28 21:43:20 +0000738- Patch #1529514: The _ctypes extension is now compiled on more
739 openbsd target platforms.
740
Tim Peters9cab5932006-07-28 00:30:00 +0000741- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
742 a memory leak, affecting pickles and deep copies.
743
Tim Petersbc24eee2006-07-27 01:14:53 +0000744- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

746
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000747- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
748
Thomas Hellerce049a02006-07-14 17:51:14 +0000749- Patch #1521817: Index range checking on ctypes arrays containing
750 exactly one element enabled again. This allows iterating over these
751 arrays, without the need to check the array size before.
752
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000753- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000754 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000755 /dev/null in certain cases; this is now fixed.
756
Thomas Heller47d7a062006-07-12 08:43:47 +0000757- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
758 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000759
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000760- Because of a misspelled preprocessor symbol, ctypes was always
761 compiled without thread support; this is now fixed.
762
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000763- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
764 methods now allow their database parameter to be None as the
765 sleepycat API allows.
766
Matt Flemingec926502006-07-28 11:27:27 +0000767- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
768 bluetooth API compared with Linux and FreeBSD.
769
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000770Tests
771-----
772
773- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
774 how long the test file should take to play. Now accepts taking 2.93 secs
775 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
776
Georg Brandl4793aa32006-07-28 18:31:39 +0000777- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
778 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
779 run via ``regrtest.py``. Now they do.

788
789- PythonLauncher now works correctly when the path to the script contains
790 characters that are treated specially by the shell (such as quotes).
791
792- Bug #1527397: PythonLauncher now launches scripts with the working directory
793 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000794 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000795 expect.

804-----------------
805
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000806- Bug #1441486: The literal representation of -(sys.maxint - 1)
807 again evaluates to a int object, not a long.
808
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000809- Bug #1501934: The scope of global variables that are locally assigned
810 using augmented assignment is now correctly determined.
811
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000812- Bug #927248: Recursive method-wrapper objects can now safely
813 be released.
814
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000815- Bug #1417699: Reject locale-specific decimal point in float()
816 and atof().
817
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000818- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
819 omit a default "error" argument for NULL pointer. This allows
820 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000821
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000822- Bug #1519018: 'as' is now validated properly in import statements.
823
Neal Norwitz28746ab2006-07-09 22:14:42 +0000824- On 64 bit systems, int literals that use less than 64 bits are
825 now ints rather than longs.
826
Neal Norwitzed657552006-07-10 00:04:44 +0000827- Bug #1512814, Fix incorrect lineno's when code at module scope
828 started after line 256.
829
Tim Peters32a83612006-07-10 21:08:24 +0000830- New function ``sys._current_frames()`` returns a dict mapping thread
831 id to topmost thread stack frame. This is for expert use, and is
832 especially useful for debugging application deadlocks. The functionality
833 was previously available in Fazal Majid's ``threadframe`` extension
834 module, but it wasn't possible to do this in a wholly threadsafe way from
835 an extension.

844
Tim Peters32a83612006-07-10 21:08:24 +0000845- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000846 environment variable to be set in order to the SDK environment
847 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +0000851- warnings.py now ignores ImportWarning by default
852
Thomas Woutersadd19112006-07-05 11:03:49 +0000853- string.Template() now correctly handles tuple-values. Previously,
854 multi-value tuples would raise an exception and single-value tuples would
855 be treated as the value they contain, instead.
856
Martin v. Löwisede77f52006-07-03 13:01:35 +0000857- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
858 even if some data are received.
859
Martin v. Löwis45482392006-07-03 12:28:58 +0000860- Bug #1267547: Put proper recursive setup.py call into the

864 degrees and radians.
865
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000866- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000867 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000868
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000869- Bug #1514703: Only setup canvas window in turtle when the canvas
870 is created.
871
Martin v. Löwis7596e832006-07-01 15:33:37 +0000872- Bug #1513223: .close() of a _socketobj now releases the underlying
873 socket again, which then gets closed as it becomes unreferenced.
874
Fred Drake10497c82006-06-29 02:57:48 +0000875- Bug #1504333: Make sgmllib support angle brackets in quoted
876 attribute values.
877
878- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
879 sgmllib ('[' and ']' were not accepted).
880
Georg Brandl1be63af2006-06-28 20:23:25 +0000881- Fix a bug in the turtle module's end_fill function.
882
Brett Cannon53ab5b72006-06-22 16:49:14 +0000883- Bug #1510580: The 'warnings' module improperly required that a Warning
884 category be either a types.ClassType and a subclass of Warning. The proper
885 check is just that it is a subclass with Warning as the documentation states.
886
Georg Brandlad29e632006-06-21 17:45:17 +0000887- The compiler module now correctly compiles the new try-except-finally
888 statement (bug #1509132).
889
Neal Norwitz60373cd2006-06-22 06:30:50 +0000890- The wsgiref package is now installed properly on Unix.
891
Vinay Sajip28e57612006-07-01 10:45:20 +0000892- A bug was fixed in logging.config.fileConfig() which caused a crash on
893 shutdown when fileConfig() was called multiple times.
894
Gerhard Häring762fbd32006-07-02 17:48:30 +0000895- The sqlite3 module did cut off data from the SQLite database at the first
896 null character before sending it to a custom converter. This has been fixed
897 now.

Tim Peters112aad32006-07-19 00:03:19 +0000902- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
903 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
904 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000905
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000906- Assigning None to pointer type fields in ctypes structures possible
907 overwrote the wrong fields, this is fixed now.
908
909- Fixed a segfault in _ctypes when ctypes.wintypes were imported
910 on non-Windows platforms.
911
912- Bug #1518190: The ctypes.c_void_p constructor now accepts any
913 integer or long, without range checking.
914
915- Patch #1517790: It is now possible to use custom objects in the ctypes
916 foreign function argtypes sequence as long as they provide a from_param
917 method, no longer is it required that the object is a ctypes type.
918
919- The '_ctypes' extension module now works when Python is configured
920 with the --without-threads option.
921
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000922- Bug #1513646: os.access on Windows now correctly determines write
923 access, again.
924
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000925- Bug #1512695: cPickle.loads could crash if it was interrupted with
926 a KeyboardInterrupt.
927
Neal Norwitza12aa882006-07-06 06:45:08 +0000928- Bug #1296433: parsing XML with a non-default encoding and
929 a CharacterDataHandler could crash the interpreter in pyexpat.
930
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000931- Patch #1516912: improve Modules support for OpenVMS.

934-----
935
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000936- Automate Windows build process for the Win64 SSL module.
937
Tim Peters32a83612006-07-10 21:08:24 +0000938- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000939 Previously, the slight difference could cause compilation errors of the
940 'zlib' module on systems with more than one version of zlib.
941
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000942- The MSI compileall step was fixed to also support a TARGETDIR
943 with spaces in it.
944
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000945- Bug #1517388: sqlite3.dll is now installed on Windows independent
946 of Tcl/Tk.
947
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000948- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000949 trying to be installed even though it's empty.

952-----
953
954- Call os.waitpid() at the end of tests that spawn child processes in order
955 to minimize resources (zombies).
956
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000957Documentation
958-------------
959
Nick Coghlan2d792252006-07-06 13:47:18 +0000960- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
961 documentation for the warnings module.
962
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000963- Patch #1509163: MS Toolkit Compiler no longer available.
964
Neal Norwitz56640df2006-07-10 02:36:41 +0000965- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000972
973Core and builtins
974-----------------
975
Georg Brandla56b9152006-06-19 06:35:54 +0000976- Patch #1507676: Error messages returned by invalid abstract object operations
977 (such as iterating over an integer) have been improved and now include the
978 type of the offending object to help with debugging.
979
Brett Cannonea3912b2006-06-13 21:46:41 +0000980- Bug #992017: A classic class that defined a __coerce__() method that returned
981 its arguments swapped would infinitely recurse and segfault the interpreter.
982
Neal Norwitz909eb122006-06-12 02:13:21 +0000983- Fix the socket tests so they can be run concurrently.
984
Neal Norwitzb9845e72006-06-12 02:11:18 +0000985- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000986 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000987
Brett Cannon22565aa2006-06-09 22:31:23 +0000988- Bug #532646: object.__call__() will continue looking for the __call__
989 attribute on objects until one without one is found. This leads to recursion
990 when you take a class and set its __call__ attribute to an instance of the
991 class. Originally fixed for classic classes, but this fix is for new-style.
992 Removes the infinite_rec_3 crasher.
993
Georg Brandl24250812006-06-09 18:45:48 +0000994- The string and unicode methods startswith() and endswith() now accept
995 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
996
Brett Cannonde3b0522006-06-08 17:00:45 +0000997- Buffer objects, at the C level, never used the char buffer
998 implementation even when the char buffer for the wrapped object was
999 explicitly requested (originally returned the read or write buffer).
1000 Now a TypeError is raised if the char buffer is not present but is
1001 requested.
1002
Georg Brandlddbaa662006-06-04 21:56:52 +00001003- Patch #1346214: Statements like "if 0: suite" are now again optimized
1004 away like they were in Python 2.4.
1005
Georg Brandlb7c8f542006-05-27 12:30:25 +00001006- Builtin exceptions are now full-blown new-style classes instead of
1007 instances pretending to be classes, which speeds up exception handling
1008 by about 80% in comparison to 2.5a2.
1009
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001010- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1011 Unicode 4.1.
1012
Georg Brandlf4ef1162006-05-26 18:03:31 +00001013- Patch #921466: sys.path_importer_cache is now used to cache valid and
1014 invalid file paths for the built-in import machinery which leads to
1015 fewer open calls on startup.
1016
Tim Peters696cf432006-05-24 21:10:40 +00001017- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1018 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1019 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1020 the number of input digits (it was and remains linear-time for bases
1021 2, 4, 8, 16 and 32).
1022
Tim Petersb713ec22006-05-23 18:45:30 +00001023- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1024 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1025 an integer close to ``sys.maxint``. This was repaired by patch
1026 #1335972, which also gives a nice speedup.
1027
Richard Jonescebbefc2006-05-23 18:28:17 +00001028- Patch #1337051: reduced size of frame objects.
1029
1030- PyErr_NewException now accepts a tuple of base classes as its
1031 "base" parameter.
1032
Richard Jones7c88dcc2006-05-23 10:37:38 +00001033- Patch #876206: function call speedup by retaining allocated frame
1034 objects.
1035
Georg Brandl7b90e162006-05-18 07:01:27 +00001036- Bug #1462152: file() now checks more thoroughly for invalid mode
1037 strings and removes a possible "U" before passing the mode to the
1038 C library function.
1039
Neal Norwitz1004a532006-05-15 07:17:23 +00001040- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1041
Neal Norwitz373f0a72006-05-15 07:04:36 +00001042- Bug #1487966: Fix SystemError with conditional expression in assignment
1043
Martin v. Löwis879768d2006-05-11 13:28:43 +00001044- WindowsError now has two error code attributes: errno, which carries
1045 the error values from errno.h, and winerror, which carries the error
1046 values from winerror.h. Previous versions put the winerror.h values
1047 (from GetLastError()) into the errno attribute.
1048
Martin v. Löwis77736712006-05-04 05:51:03 +00001049- Patch #1475845: Raise IndentationError for unexpected indent.
1050
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001051- Patch #1479181: split open() and file() from being aliases for each other.
1052
Tim Peters44bd9862006-06-01 13:49:23 +00001053- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1054 methods were always silently ignored by dictionaries when comparing keys.
1055 They are now passed through (except when using the C API function
1056 ``PyDict_GetItem()``, whose semantics did not change).
1057
1058- Bug #1456209: In some obscure cases it was possible for a class with a
1059 custom ``__eq__()`` method to confuse dict internals when class instances
1060 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1061 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001063Extension Modules
1064-----------------
1065
Trent Mick960a3f82006-06-28 20:30:41 +00001066- Bug #1295808: expat symbols should be namespaced in pyexpat
1067
1068- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1069
Brett Cannon6ee7d012006-06-08 16:23:04 +00001070- Change binascii.hexlify to accept a read-only buffer instead of only a char
1071 buffer and actually follow its documentation.
1072
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001073- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1074
Nick Coghlanc649ec52006-05-29 12:43:05 +00001075- Patch #1478788 (modified version): The functional extension module has
1076 been renamed to _functools and a functools Python wrapper module added.
1077 This provides a home for additional function related utilities that are
1078 not specifically about functional programming. See PEP 309.
1079
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001080- Patch #1493701: performance enhancements for struct module.
1081
Georg Brandl378d5922006-05-17 14:26:50 +00001082- Patch #1490224: time.altzone is now set correctly on Cygwin.
1083
Georg Brandl8d3342b2006-05-16 07:38:27 +00001084- Patch #1435422: zlib's compress and decompress objects now have a
1085 copy() method.
1086
Andrew MacIntyre92913322006-06-13 15:04:24 +00001087- Patch #1454481: thread stack size is now tunable at runtime for thread
1088 enabled builds on Windows and systems with Posix threads support.
1089
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001090- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1091 (up to the system limit of 32K characters).
1092
1093- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1094 As a result, these functions now raise WindowsError instead of OSError.
1095
Tim Peters7a822da2006-05-25 21:50:17 +00001096- ``time.clock()`` on Win64 should use the high-performance Windows
1097 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1098 Windows platforms).
1099
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001100- Calling Tk_Init twice is refused if the first call failed as that
1101 may deadlock.
1102
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001103- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1104 accept it without potentially using an uninitialized pointer.
1105
1106- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1107 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1108 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001109
Gregory P. Smith372b5832006-06-05 18:48:21 +00001110- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001111 [pybsddb project SF patch number 1466734]
1112
Gregory P. Smith372b5832006-06-05 18:48:21 +00001113- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1114 parameter is supplied. [SF pybsddb bug #1477863]
1115
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001116- bsddb: the __len__ method of a DB object has been fixed to return correct
1117 results. It could previously incorrectly return 0 in some cases.
1118 Fixes SF bug 1493322 (pybsddb bug 1184012).
1119
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001120- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1121 aborts the db transaction safely when a modifier callback fails.
1122 Fixes SF python patch/bug #1408584.
1123
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001124- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001125 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001126 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1127 database calls that would previously deadlock. [SF python bug #775414]
1128
Vinay Sajip28e57612006-07-01 10:45:20 +00001129- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001130
Walter Dörwald4994d952006-06-19 08:07:50 +00001131- Patch #1506645: add Python wrappers for the curses functions
1132 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001133

1135-------
1136
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001137- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1138 functions.
1139
Martin v. Löwis3798da02006-06-17 18:44:27 +00001140- Patch #812986: Update turtle output even if not tracing.
1141
Vinay Sajip28e57612006-07-01 10:45:20 +00001142- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001143 Tkinter.BaseWidget.
1144
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001145- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1146
Martin v. Löwis337487e2006-06-17 09:15:14 +00001147- Patch #763580: Add name and value arguments to Tkinter variable
1148 classes.
1149
Georg Brandl83cc0d02006-06-14 08:50:03 +00001150- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1151 mime.types file for determining MIME types.
1152
Georg Brandl2605ca82006-06-14 06:08:31 +00001153- Bug #1339007: Shelf objects now don't raise an exception in their
1154 __del__ method when initialization failed.
1155
Martin v. Löwisd8251432006-06-14 05:21:04 +00001156- Patch #1455898: The MBCS codec now supports the incremental mode for
1157 double-byte encodings.
1158
Tim Peters43898b42006-06-14 04:09:25 +00001159- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1160 guarantee that adjacent triples in the return list always describe
1161 non-adjacent blocks. Previously, a pair of matching blocks could end
1162 up being described by multiple adjacent triples that formed a partition
1163 of the matching pair.
1164
Greg Ward0e0c9f42006-06-11 16:24:11 +00001165- Bug #1498146: fix optparse to handle Unicode strings in option help,
1166 description, and epilog.
1167
Greg Wardd1c797e2006-06-11 14:42:41 +00001168- Bug #1366250: minor optparse documentation error.
1169
Greg Ward7f547402006-06-11 00:40:49 +00001170- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1171 clarify docs.
1172
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001173- The wsgiref package has been added to the standard library.
1174
Nick Coghlan676725d2006-06-08 13:54:49 +00001175- The functions update_wrapper() and wraps() have been added to the functools
1176 module. These make it easier to copy relevant metadata from the original
1177 function when writing wrapper functions.
1178
Tim Petersd6a9eef2006-06-05 01:48:21 +00001179- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1180 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001181
Martin v. Löwis3f767792006-06-04 19:36:28 +00001182- Patch #1359618: Speed up charmap encoder by using a trie structure
1183 for lookup.
1184
Tim Petersd609b1a2006-06-02 23:22:51 +00001185- The functions in the ``pprint`` module now sort dictionaries by key
1186 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1187 if and only if its display required more than one line, although that
1188 wasn't documented. The new behavior increases predictability; e.g.,
1189 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1190
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001191- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1260
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001261What's New in Python 2.5 alpha 2?
1262=================================
1263
1264*Release date: 27-APR-2006*
1265
1266Core and builtins
1267-----------------
1268
Thomas Heller1b046642006-04-18 18:51:06 +00001269- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1270 by converting these apis from macros into exported functions again:
1271
1272 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1273 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1274 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1275 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1276 PyRun_String Py_CompileString
1277
Martin v. Löwis45294a92006-04-18 06:24:08 +00001278- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1279
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001280- All uses of PyStructSequence_InitType have been changed to initialize
1281 the type objects only once, even if the interpreter is initialized
1282 multiple times.
1283
Neal Norwitz61546162006-04-14 05:20:28 +00001284- Bug #1454485, array.array('u') could crash the interpreter. This was
1285 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1286 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1287
1288- Py_UNICODE is unsigned. It was always documented as unsigned, but
1289 due to a bug had a signed value in previous versions.
1290
Tim Peters3a5e8b12006-04-11 01:44:07 +00001291- Patch #837242: ``id()`` of any Python object always gives a positive
1292 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1293 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001294 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001295 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001296
Tim Peters3a5e8b12006-04-11 01:44:07 +00001297 def __hash__(self):
1298 return id(self) # WRONG
1299
1300 because a hash result must be a (short) Python int but it was always
1301 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001302 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001303 was always usable as a hash value before this patch. That's no longer
1304 necessarily so.
1305
1306- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001307 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001308 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001309 #1454844)
1310
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001311- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1312 involving generators that have paused outside of any ``try`` or ``with``
1313 blocks. (In 2.5a1, a paused generator that was part of a reference
1314 cycle could not be garbage collected, regardless of whether it was
1315 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001316
Anthony Baxter51bcb682006-04-05 14:51:42 +00001317Extension Modules
1318-----------------
1319
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001320- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1321 is a macro.
1322
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001323- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1324 fails with an error condition.
1325
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001326- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1327
1328- Bug #1117761: bsddb.*open() no longer raises an exception when using
1329 the cachesize parameter.
1330
1331- Bug #1149413: bsddb.*open() no longer raises an exception when using
1332 a temporary db (file=None) with the 'n' flag to truncate on open.
1333
1334- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1335 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001336
Armin Rigoa9017c32006-04-19 11:50:27 +00001337- Patch #1062014: AF_UNIX sockets under Linux have a special
1338 abstract namespace that is now fully supported.
1339
Anthony Baxter51bcb682006-04-05 14:51:42 +00001340Library
1341-------
1342
Peter Astrand7d1d4362006-07-14 14:04:45 +00001343- Bug #1223937: subprocess.CalledProcessError reports the exit status
1344 of the process using the returncode attribute, instead of
1345 abusing errno.
1346
Tim Peters711bf302006-04-25 03:31:36 +00001347- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1348 a doctest to be skipped (the code is not run, and the expected output
1349 or exception is ignored).
1350
Nick Coghlanda2268f2006-04-24 04:37:15 +00001351- Fixed contextlib.nested to cope with exceptions being raised and
1352 caught inside exit handlers.
1353
Greg Wardab05edc2006-04-23 03:47:58 +00001354- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1355 hex, octal, or binary; add ``append_const`` action; keep going if
1356 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1357 added ``epilog`` for better help generation).
1358
Tim Peters21fbd572006-04-21 21:18:10 +00001359- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1360 called from a thread spawned as a side effect of importing a module.
1361
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001362- The pydoc module now supports documenting packages contained in
1363 .zip or .egg files.
1364
1365- The pkgutil module now has several new utility functions, such
1366 as ``walk_packages()`` to support working with packages that are either
1367 in the filesystem or zip files.
1368
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001369- The mailbox module can now modify and delete messages from
1370 mailboxes, in addition to simply reading them. Thanks to Gregory
1371 K. Johnson for writing the code, and to the 2005 Google Summer of
1372 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001373
Tim Petersc7605f22006-04-17 21:12:33 +00001374- The ``__del__`` method of class ``local`` in module ``_threading_local``
1375 returned before accomplishing any of its intended cleanup.
1376
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001377- Patch #790710: Add breakpoint command lists in pdb.
1378
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001379- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1380
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001381- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1382
Anthony Baxtere29002c2006-04-12 12:07:31 +00001383- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1384 Windows. Bug #1469163.
1385
Phillip J. Eby47032112006-04-11 01:07:43 +00001386- The warnings, linecache, inspect, traceback, site, and doctest modules
1387 were updated to work correctly with modules imported from zipfiles or
1388 via other PEP 302 __loader__ objects.
1389
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001390- Patch #1467770: Reduce usage of subprocess._active to processes which
1391 the application hasn't waited on.
1392
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001393- Patch #1462222: Fix Tix.Grid.
1394
Neal Norwitza31bf182006-04-09 03:35:43 +00001395- Fix exception when doing glob.glob('anything*/')
1396
Skip Montanaro262fb922006-04-21 02:31:07 +00001397- The pstats.Stats class accepts an optional stream keyword argument to
1398 direct output to an alternate file-like object.
1399
Anthony Baxter51bcb682006-04-05 14:51:42 +00001400Build
1401-----
1402
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001403- The Makefile now has a reindent target, which runs reindent.py on
1404 the library.
1405
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001406- Patch #1470875: Building Python with MS Free Compiler
1407
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001408- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001409
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001410- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1411 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001412 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001413 CXX from --with-cxx-main, see description in README.
1414
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001415- Patch #1429775: Link extension modules with the shared libpython.
1416
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001417- Fixed a libffi build problem on MIPS systems.
1418
Tim Peters8931ff12006-05-13 23:28:20 +00001419- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1420 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1421 and "%zu" for unsigned integers of type ``size_t``.
1422
Anthony Baxter51bcb682006-04-05 14:51:42 +00001423Tests
1424-----
1425
Nick Coghlanda2268f2006-04-24 04:37:15 +00001426- test_contextlib now checks contextlib.nested can cope with exceptions
1427 being raised and caught inside exit handlers.
1428
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001429- test_cmd_line now checks operation of the -m and -c command switches
1430
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001431- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1432 it separately and by hand. It also wasn't cleaning up its changes to
1433 the current Decimal context.
1434
Thomas Woutersabd08882006-04-26 15:53:30 +00001435- regrtest.py now has a -M option to run tests that test the new limits of
1436 containers, on 64-bit architectures. Running these tests is only sensible
1437 on 64-bit machines with more than two gigabytes of memory. The argument
1438 passed is the maximum amount of memory for the tests to use.
1439
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001440Tools
1441-----
1442
1443- Added the Python benchmark suite pybench to the Tools/ directory;
1444 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001445

1447-------------
1448
Tim Petersb06d28c2006-05-12 01:57:59 +00001449- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1450
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001451- PEP 343: Added Context Types section to the library reference
1452 and attempted to bring other PEP 343 related documentation into
1453 line with the implementation and/or python-dev discussions.
1454
Tim Peters8dc73d22006-04-24 02:03:16 +00001455- Bug #1337990: clarified that ``doctest`` does not support examples
1456 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001459What's New in Python 2.5 alpha 1?
1460=================================
1461
Anthony Baxterebed3f62006-04-03 15:03:44 +00001462*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001463
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001464Core and builtins
1465-----------------
1466
Nick Coghlan43832302006-04-23 17:04:07 +00001467- PEP 338: -m command line switch now delegates to runpy.run_module
1468 allowing it to support modules in packages and zipfiles
1469
Martin v. Löwisc661b882006-04-20 04:54:23 +00001470- On Windows, .DLL is not an accepted file name extension for
1471 extension modules anymore; extensions are only found if they
1472 end in .PYD.
1473
Martin v. Löwisea62d252006-04-03 10:56:49 +00001474- Bug #1421664: sys.stderr.encoding is now set to the same value as
1475 sys.stdout.encoding.
1476
Neal Norwitz92e212f2006-04-03 04:48:37 +00001477- __import__ accepts keyword arguments.
1478
Georg Brandlccadf842006-03-31 18:54:53 +00001479- Patch #1460496: round() now accepts keyword arguments.
1480
Anthony Baxter262c00a2006-03-30 10:53:17 +00001481- Fixed bug #1459029 - unicode reprs were double-escaped.
1482
Hye-Shik Changd478f342006-03-23 12:32:36 +00001483- Patch #1396919: The system scope threads are reenabled on FreeBSD
1484 5.4 and later versions.
1485
Neal Norwitze98ccf62006-03-23 05:39:47 +00001486- Bug #1115379: Compiling a Unicode string with an encoding declaration
1487 now gives a SyntaxError.
1488
Georg Brandlabd1ff82006-03-18 07:59:59 +00001489- Previously, Python code had no easy way to access the contents of a
1490 cell object. Now, a ``cell_contents`` attribute has been added
1491 (closes patch #1170323).
1492
Tim Peterscf79aac2006-03-16 01:14:46 +00001493- Patch #1123430: Python's small-object allocator now returns an arena to
1494 the system ``free()`` when all memory within an arena becomes unused
1495 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1496 freed. Some applications will see a drop in virtual memory size now,
1497 especially long-running applications that, from time to time, temporarily
1498 use a large number of small objects. Note that when Python returns an
1499 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001500 platform C library will in turn return that memory to the operating system.
1501 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001502 appears to be effective at least on Microsoft C and gcc-based systems.
1503 Thanks to Evan Jones for hard work and patience.
1504
Georg Brandl533ff6f2006-03-08 18:09:27 +00001505- Patch #1434038: property() now uses the getter's docstring if there is
1506 no "doc" argument given. This makes it possible to legitimately use
1507 property() as a decorator to produce a read-only property.
1508
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001509- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1510 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1511 of requiring an int or long in slicing and a few other contexts, enabling
1512 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1513
Neal Norwitz995acdf2006-03-07 05:01:00 +00001514- Fixed various bugs reported by Coverity's Prevent tool.
1515
Brett Cannonbf364092006-03-01 04:25:17 +00001516- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1517 new exception base class, BaseException, which has a new message attribute.
1518 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1519 Raising a string exception now raises a DeprecationWarning.
1520
Thomas Woutersfb609f42006-02-28 16:37:25 +00001521- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1522 explicitly relative, using 'from .module import name' to mean 'from the same
1523 package as this module is in. Imports without dots still default to the
1524 old relative-then-absolute, unless 'from __future__ import
1525 absolute_import' is used.
1526
Brett Cannona7446e32006-02-27 23:39:10 +00001527- Properly check if 'warnings' raises an exception (usually when a filter set
1528 to "error" is triggered) when raising a warning for raising string
1529 exceptions.
1530
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001531- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001532 The name was removed from Include/code.h.
1533
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001534- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001535
Guido van Rossum1968ad32006-02-25 22:38:04 +00001536- Patch 1433928:
1537 - The copy module now "copies" function objects (as atomic objects).
1538 - dict.__getitem__ now looks for a __missing__ hook before raising
1539 KeyError.
1540
Tim Peters84ef21c2006-02-28 20:39:06 +00001541- PEP 343: with statement implemented. Needs ``from __future__ import
1542 with_statement``. Use of 'with' as a variable will generate a warning.
1543 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001544 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001545 The following objects have __context__ methods:
1546 - The built-in file type.
1547 - The thread.LockType type.
1548 - The following types defined by the threading module:
1549 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1550 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001551
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001552- Fix the encodings package codec search function to only search
1553 inside its own package. Fixes problem reported in patch #1433198.
1554
1555 Note: Codec packages should implement and register their own
1556 codec search function. PEP 100 has the details.
1557
Tim Peters9ea89d22006-06-04 03:26:02 +00001558- PEP 353: Using ``Py_ssize_t`` as the index type.
1559
1560- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1561 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1562 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1563 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1564 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001565
Neal Norwitzfc76d632006-01-10 06:03:13 +00001566- Patch #1400181, fix unicode string formatting to not use the locale.
1567 This is how string objects work. u'%f' could use , instead of .
1568 for the decimal point. Now both strings and unicode always use periods.
1569
Neal Norwitz671b9e32006-01-09 07:07:12 +00001570- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1571 configure would break checking curses.h.
1572
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001573- Bug #959576: The pwd module is now builtin. This allows Python to be
1574 built on UNIX platforms without $HOME set.
1575
Neal Norwitzc10978f2005-12-19 06:07:16 +00001576- Bug #1072182, fix some potential problems if characters are signed.
1577
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001578- Bug #889500, fix line number on SyntaxWarning for global declarations.
1579
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001580- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1581
Neal Norwitze7214a12005-12-18 05:03:17 +00001582- Support for converting hex strings to floats no longer works.
1583 This was not portable. float('0x3') now raises a ValueError.
1584
Barry Warsaw2a38a862005-12-18 01:27:35 +00001585- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001586 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001587 is now displayed in interactive prompt banner.
1588
Georg Brandlfa166682005-12-17 21:45:17 +00001589- Implementation of PEP 341 - Unification of try/except and try/finally.
1590 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001591 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001592
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001593- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1594 now encodes backslash correctly.
1595
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001596- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1597
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001598- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001599 and long longs.
1600
Neal Norwitz67715f02005-11-09 06:59:35 +00001601- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001602 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001603 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001604
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001605- Replaced most Unicode charmap codecs with new ones using the
1606 new Unicode translate string feature in the builtin charmap
1607 codec; the codecs were created from the mapping tables available
1608 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1609 encodings now include a mapping for the Apple logo)
1610
Tim Peterse3547fd2005-12-16 23:13:57 +00001611- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001612
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001613- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001614
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001615- A new AST parser implementation was completed. The abstract
1616 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001617 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001618
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001619- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001620 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1621
Neal Norwitz708e51a2005-10-03 04:48:15 +00001622- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1623
Neal Norwitz11bd1192005-10-03 00:54:56 +00001624- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1625 Provide a warning when a directory is passed on the command line.
1626
Neal Norwitz40d37812005-10-02 01:48:49 +00001627- Fix segfault with invalid coding.
1628
1629- SF bug #772896: unknown encoding results in MemoryError.
1630
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001631- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001632 supported a __len__() method which evaluated to False when the iterator
1633 was empty.
1634
Guido van Rossum630db602005-09-20 18:49:54 +00001635- On 64-bit platforms, when __len__() returns a value that cannot be
1636 represented as a C int, raise OverflowError.
1637
Skip Montanarof8948ca2005-09-19 03:54:46 +00001638- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001639 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001640
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001641- SF bug #893549: parsing keyword arguments was broken with a few format
1642 codes.
1643
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001644- Changes donated by Elemental Security to make it work on AIX 5.3
1645 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1646 bug #105470: test_pwd fails on 64bit system (Opteron).
1647
Guido van Rossum539c6622005-09-14 17:49:54 +00001648- Changes donated by Elemental Security to make it work on HP-UX 11 on
1649 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1650
Georg Brandl4550b8d2005-08-26 06:43:52 +00001651- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001652 (fixes bug #1119418).
1653
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001654- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1655
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001656- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1657 exceptions that cause a function to exit.
1658
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001659- The implementation of set() and frozenset() was revised to use its
1660 own internal data structure. Memory consumption is reduced by 1/3
1661 and there are modest speed-ups as well. The API is unchanged.
1662
Tim Petersde7990b2005-07-17 23:45:23 +00001663- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1664
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001665- SF bug #1229429: PyObject_CallMethod failed to decrement some
1666 reference counts in some error exit cases.
1667
Tim Petersecc6e6a2005-07-10 22:30:55 +00001668- SF bug #1185883: Python's small-object memory allocator took over
1669 a block managed by the platform C library whenever a realloc specified
1670 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001671 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001672 portable way to copy data from the C-managed block into Python's
1673 small-object space without risking a memory fault. Python's small-object
1674 realloc now leaves such blocks under the control of the platform C
1675 realloc.
1676
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001677- SF bug #1232517: An overflow error was not detected properly when
1678 attempting to convert a large float to an int in os.utime().
1679
Raymond Hettinger3296e692005-06-29 23:29:56 +00001680- SF bug #1224347: hex longs now print with lowercase letters just
1681 like their int counterparts.
1682
Michael W. Hudson188d4362005-06-20 16:52:57 +00001683- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1684 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1685 interpreter states; back out that fix and do a better job (see
1686 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1687 for a longer write-up of the problem).
1688
Michael W. Hudsondf888462005-06-03 14:41:55 +00001689- SF patch #1180995: marshal now uses a binary format by default when
1690 serializing floats.
1691
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001692- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1693 the routines that promise to produce IEEE 754 binary representations
1694 of floats now simply copy bytes around.
1695
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001696- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1697 278.
1698
Brett Cannonc3647ac2005-04-26 03:45:26 +00001699- patch #1109424: int, long, float, complex, and unicode now check for the
1700 proper magic slot for type conversions when subclassed. Previously the
1701 magic slot was ignored during conversion. Semantics now match the way
1702 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001703 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001704 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001705 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001706
Barry Warsawc8d907c2005-04-19 23:43:40 +00001707- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1708 NULL, now raise an AttributeError when attempting to set or delete the
1709 attribute. Previously a TypeError was raised, but this was inconsistent
1710 with the equivalent pure-Python implementation.
1711
Michael W. Hudson774479c2005-04-18 08:46:17 +00001712- It is now safe to call PyGILState_Release() before
1713 PyEval_InitThreads() (note that if there is reason to believe there
1714 are multiple threads around you still must call PyEval_InitThreads()
1715 before using the Python API; this fix is for extension modules that
1716 have no way of knowing if Python is multi-threaded yet).
1717
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001718- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1719 disabled caused a crash.
1720
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001721- Bug #1165306: instancemethod_new allowed the creation of a method
1722 with im_class == im_self == NULL, which caused a crash when called.
1723
Tim Petersecc6e6a2005-07-10 22:30:55 +00001724- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001725 fixes the crash seen in bug #1165761
1726
Raymond Hettinger96229b12005-03-11 06:49:40 +00001727- Added two new builtins, any() and all().
1728
Brett Cannon409d8f22005-03-05 06:47:57 +00001729- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001730 (e.g., ``class C(): pass`` is no longer a syntax error).
1731 Patch #1176012 added support to the 'parser' module and 'compiler' package
1732 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001733
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001734- Patch #1115086: Support PY_LONGLONG in structmember.
1735
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001736- Bug #1155938: new style classes did not check that __init__() was
1737 returning None.
1738
Tim Petersecc6e6a2005-07-10 22:30:55 +00001739- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001740 ('\') with a specific error message.
1741
Martin v. Löwisff232d72005-03-03 09:24:38 +00001742- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1743
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001744- Bug #1124295: the __name__ attribute of file objects was
1745 inadvertently made inaccessible in restricted mode.
1746
Tim Petersecc6e6a2005-07-10 22:30:55 +00001747- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001748 an ferror() call.
1749
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001750- min() and max() now support key= arguments with the same meaning as in
1751 list.sort().
1752
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001753- The peephole optimizer now performs simple constant folding in expressions:
1754 (2+3) --> (5).
1755
Raymond Hettingera422c342005-01-11 03:03:27 +00001756- set and frozenset objects can now be marshalled. SF #1098985.
1757
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001758- Bug #1077106: Poor argument checking could cause memory corruption
1759 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001760
Jeremy Hyltonab630502005-02-04 18:44:06 +00001761- The parser did not complain about future statements in illegal
1762 positions. It once again reports a syntax error if a future
1763 statement occurs after anything other than a doc string.
1764
Neil Schemenauercf52c072005-08-12 17:34:58 +00001765- Change the %s format specifier for str objects so that it returns a
1766 unicode instance if the argument is not an instance of basestring and
1767 calling __str__ on the argument returns a unicode instance.
1768
Tim Petersf4e69282006-02-27 17:15:31 +00001769- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1770 current thread state when the auto-GIL-state machinery knows about
1771 it (since the thread state is being deleted, continuing to remember it
1772 can't help, but can hurt if another thread happens to get created with
1773 the same thread id).

1906 the request code argument, which results in more C-like behaviour
1907 for large or negative values.
1908
Tim Petersecc6e6a2005-07-10 22:30:55 +00001909- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1924
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001925- operator.itemgetter() and operator.attrgetter() now support retrieving

1950 args tuple returned by __reduce__().
1951
Raymond Hettingerb2594052004-12-05 09:25:51 +00001952- itertools.islice() now accepts None for the start and step arguments.

1954 islice(s.start, s.stop, s.step)
1955
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001956- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001965- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1966 been renamed to have only a single underscore prefix. This was done to
1967 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001968
Nick Coghlan43832302006-04-23 17:04:07 +00001969- PEP 338: new module runpy defines a run_module function to support
1970 executing modules which provide access to source code or a code object
1971 via the PEP 302 import mechanisms.
1972
Anthony Baxter93f5b932006-04-03 08:05:07 +00001973- The email module's parsedate_tz function now sets the daylight savings

1981 in attribute values.
1982
Anthony Baxterc51ee692006-04-01 00:57:31 +00001983- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001984 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001985 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001986 module will not be built.
1987
Tim Petersc17976e2006-04-01 00:26:53 +00001988- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1989 aren't officially supported here, and trying to use them will probably
1990 raise an exception some day. But dicts have been allowed, and "mostly
1991 worked", so support for them won't go away without warning.
1992
Georg Brandl338ef7d2006-03-31 18:42:16 +00001993- Bug #1445068: getpass.getpass() can now be given an explicit stream
1994 argument to specify where to write the prompt.
1995
Georg Brandl22ec80b2006-03-31 18:25:44 +00001996- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2011
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002012- email 4.0 package now integrated. This is largely the same as the email 3.0
2013 package that was included in Python 2.3, except that PEP 8 module names are
2014 now used (e.g. mail.message instead of email.Message). The MIME classes
2015 have been moved to a subpackage (e.g. email.mime.text instead of
2016 email.MIMEText). The old names are still supported for now. Several
2017 deprecated Message methods have been removed and lots of bugs have been
2018 fixed. More details can be found in the email package documentation.
2019
Walter Dörwald40108c92006-03-27 08:15:44 +00002020- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2021 (a subclass of tuple) that provides incremental decoders and encoders
2022 (a way to use stateful codecs without the stream API). Python functions
2023 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2024 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2025 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002027- Patch #1359365: Calling next() on a closed StringIO.String object raises
2028 a ValueError instead of a StopIteration now (like file and cString.String do).
2029 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been

2109 "The consensus of researchers in this area (at least as
2110 expressed at the NIST Hash Function Workshop 10/31/05),
2111 is that SHA-256 is a good choice for the time being, but
2112 that research should continue, and other alternatives may
2113 arise from this research. The larger SHA's also seem OK."

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002289- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2290
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002291- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2292
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002293- Enhancements to the csv module:
2294
2295 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002296 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002297 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002298 + Dialect parameter parsing has been re-implemented to improve error
2299 reporting.
2300 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2301 dictates.
2302 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002303 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002304 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002305 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2306 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002307 + reader now allows \r characters to be quoted (previously it only allowed
2308 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002309 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002310 + Dialect classes passed to the module are no longer instantiated by
2311 the module before being parsed (the former validation scheme required
2312 this, but the mechanism was unreliable).
2313 + The dialect registry now contains instances of the internal
2314 C-coded dialect type, rather than references to python objects.
2315 + the internal c-coded dialect type is now immutable.
2316 + register_dialect now accepts the same keyword dialect specifications
2317 as the reader and writer, allowing the user to register dialects
2318 without first creating a dialect class.
2319 + a configurable limit to the size of parsed fields has been added -
2320 previously, an unmatched quote character could result in the entire
2321 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002322 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002323 the parser field size limit (returning the former limit). The initial
2324 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002325 + A line_num attribute has been added to the reader object, which tracks
2326 the number of lines read from the source iterator. This is not
2327 the same as the number of records returned, as records can span
2328 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002329 + reader and writer objects were not being registered with the cyclic-GC.
2330 This has been fixed.
2331
Brett Cannone6539c42005-01-08 02:43:53 +00002332- _DummyThread objects in the threading module now delete self.__block that is
2333 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2334 lock primitives tend to be limited in number and thus should not be wasted on
2335 a _DummyThread object. Fixes bug #1089632.
2336
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002337- The imghdr module now detects Exif files.
2338
Raymond Hettinger6065d322004-12-20 23:51:53 +00002339- StringIO.truncate() now correctly adjusts the size attribute.
2340 (Bug #951915).
2341
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002342- locale.py now uses an updated locale alias table (built using
2343 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2344 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002345 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002346
Raymond Hettinger3557f422004-12-07 12:02:02 +00002347- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2348
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002349- the pickle module no longer accepts the deprecated None option in the
2350 args tuple returned by __reduce__().
2351
Brett Cannon84667c02004-12-07 03:25:18 +00002352- optparse now optionally imports gettext. This allows its use in setup.py.
2353
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002354- the pickle module no longer uses the deprecated bin parameter.
2355
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002356- the shelve module no longer uses the deprecated binary parameter.
2357
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002358- the pstats module no longer uses the deprecated ignore() method.
2359
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002360- the filecmp module no longer uses the deprecated use_statcache argument.
2361
Raymond Hettinger664347b2004-12-04 21:21:53 +00002362- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2363 extended or overridden by subclasses. Formerly, the subclassed method would
2364 be ignored by the rest of the module. (Bug #1078905).
2365
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002366- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002367 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002368
Walter Dörwald36733692004-12-22 12:50:50 +00002369- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2370 once when a size argument is given. This prevents a buffer overflow in the
2371 tokenizer with very long source lines.
2372
Barry Warsaw538561e2006-01-01 21:48:54 +00002373- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2374 immediately after creating the object, without any intervening
2375 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002376
Skip Montanaro05885812005-01-16 20:48:27 +00002377- The reconvert.quote function can now emit triple-quoted strings. The
2378 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002379
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002380- ``UserString.MutableString`` now supports negative indices in
2381 ``__setitem__`` and ``__delitem__``
2382
Greg Ward40407942005-03-05 02:53:17 +00002383- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2384 correctly.
2385
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002386- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2387 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2388 character even if the user has passed a size parameter to get a proper
2389 line ending. Remove the special handling of a "\r\n" that has been split
2390 between two lines.
2391
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002392- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2393 about illegal code points. The codec now supports PEP 293 style error
2394 handlers.
2395
Walter Dörwald78a78b02005-09-01 12:04:29 +00002396- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002397 from the input stream, so that the output is a byte string in the correct
2398 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002399
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002400- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2401 considering it exactly like a '*'.
2402
Walter Dörwald007f8df2005-10-09 19:42:27 +00002403- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2404 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002405
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002406- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2407
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002408- Patch #1413711: Certain patterns of differences were making difflib
2409 touch the recursion limit.
2410
Walter Dörwald58917a62006-03-31 15:26:22 +00002411- Bug #947906: An object oriented interface has been added to the calendar
2412 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002413 called as a script (e.g. via ``python -mcalendar``). Localized month and
2414 weekday names can be ouput (even if an exotic encoding is used) using
2415 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002416
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002417Build
2418-----
2419
Neal Norwitz602d3392006-03-31 08:21:40 +00002420- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2421 by using -mieee gcc option.
2422
Martin v. Löwis86d66262006-02-17 08:40:11 +00002423- Patch #1432345: Make python compile on DragonFly.
2424
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002425- Build support for Win64-AMD64 was added.
2426
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002427- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2428
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002429- Patch #881820: look for openpty and forkpty also in libbsd.
2430
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002431- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2432 The zlib module is now builtin on Windows.
2433
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002434- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2435
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002436- Bug #1189330: configure did not correctly determine the necessary
2437 value of LINKCC if python was built with GCC 4.0.
2438
Trent Mick8321b422005-07-26 02:29:21 +00002439- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2440 vulnerability in zlib 1.2.1 and 1.2.2.
2441
Brett Cannon08cd5982005-04-24 22:26:38 +00002442- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2443 flags that change binary compatibility. Changes were also made to
2444 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002445 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002446
Bob Ippolitoed233462005-03-29 13:47:59 +00002447- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2448 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2449 no longer exists). This configure patch makes things right.
2450
Martin v. Löwise2713be2005-03-08 15:03:08 +00002451- Bug #1158607: Build with --disable-unicode again.
2452
Brett Cannon46d96232005-02-16 00:07:19 +00002453- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2454 defined. Discovered as a result of not being able to build on OS X.
2455
Brett Cannon516592f2004-12-07 00:42:59 +00002456- setup.py now uses the directories specified in LDFLAGS using the -L option
2457 and in CPPFLAGS using the -I option for adding library and include
2458 directories, respectively, for compiling extension modules against. This has
2459 led to the core being compiled using the values in CPPFLAGS. It also removes
2460 the need for the special-casing of both DarwinPorts and Fink for darwin since
2461 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2462 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2463 Fink, ``-I/opt/local/include`` for DarwinPorts).
2464
Brett Cannon43802422005-02-10 20:48:03 +00002465- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2466 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2467 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2468 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002470C API
2471-----
2472
Tim Petersc9d78aa2006-03-26 23:27:58 +00002473- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2474 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2475 is obtained via the ``PyObject_`` family, it must be released via the
2476 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2477 always been officially true, but when Python's small-object allocator was
2478 introduced, an attempt was made to cater to a few extension modules
2479 discovered at the time that obtained memory via ``PyObject_New`` but
2480 released it via ``PyMem_DEL``. It's years later, and if such code still
2481 exists it will fail now (probably with segfaults, but calling wrong
2482 low-level memory management functions can yield many symptoms).
2483
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002484- Added a C API for set and frozenset objects.
2485
Raymond Hettinger66517482004-12-03 11:45:13 +00002486- Removed PyRange_New().
2487
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002488- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2489 mapping argument now. This string is used as a mapping table. Byte values
2490 greater than the length of the string and 0xFFFE are treated as undefined
2491 mappings.
