369
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000370- Make _PyGILState_NoteThreadState() static, it was not used anywhere
371 outside of pystate.c and should not be necessary.
372
Brett Cannon19d76c52006-09-09 07:18:44 +0000373- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
374 allows calling unicode() on exceptions classes directly to succeed.
375
Georg Brandlecab6232006-09-06 06:47:02 +0000376- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000391- The return tuple from str.rpartition(sep) is (tail, sep, head) where
392 head is the original string if sep was not found.
393
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000394- Bug #1520864: unpacking singleton tuples in list comprehensions and
395 generator expressions (x for x, in ... ) works again. Fixing this problem
396 required changing the .pyc magic number. This means that .pyc files
397 generated before 2.5c2 will be regenerated.

500Core and builtins
501-----------------
502
Neal Norwitz24b6f202006-09-05 04:43:56 +0000503- Fix infinite recursion when subclassing long and overriding __hash__.
504
505- Fix concatenation (+=) of long strings.
506
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000507- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000508 compared equal or unequal to a string and a UnicodeDecodeError
509 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000510
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000511 Instead, the equal (==) and unequal (!=) comparison operators will
512 now issue a UnicodeWarning and interpret the two objects as
513 unequal. The UnicodeWarning can be filtered as desired using
514 the warning framework, e.g. silenced completely, turned into an
515 exception, logged, etc.
516
517 Note that compare operators other than equal and unequal will still
518 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000519
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000520- Fix segfault when doing string formatting on subclasses of long.
521
522- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
523 with new-style classes.
524
525- Fix bug related to __len__ functions returning negative values with
526 classic classes.
527
528- Patch #1538606, Fix __index__() clipping. There were some problems
529 discovered with the API and how integers that didn't fit into Py_ssize_t
530 were handled. This patch attempts to provide enough alternatives
531 to effectively use __index__.
532
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000533- Bug #1536021: __hash__ may now return long int; the final hash
534 value is obtained by invoking hash on the long int.
535
Thomas Hellerab1049c2006-08-08 17:37:00 +0000536- Bug #1536786: buffer comparison could emit a RuntimeWarning.

539 sys.stdin is closed.
540
Thomas Heller74d36f02006-08-04 18:17:40 +0000541- On Windows, the PyErr_Warn function is now exported from
542 the Python dll again.
543
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000544- Bug #1191458: tracing over for loops now produces a line event
545 on each iteration. Fixing this problem required changing the .pyc
546 magic number. This means that .pyc files generated before 2.5c1
547 will be regenerated.
548
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000549- Bug #1333982: string/number constants were inappropriately stored
550 in the byte code and co_consts even if they were not used, ie
551 immediately popped off the stack.
552
Georg Brandle9462c72006-08-04 18:03:37 +0000553- Fixed a reference-counting problem in property().

557-------
558
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000559- Fix a bug in the ``compiler`` package that caused invalid code to be
560 generated for generator expressions.
561
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000562- The distutils version has been changed to 2.5.0. The change to
563 keep it programmatically in sync with the Python version running
564 the code (introduced in 2.5b3) has been reverted. It will continue
565 to be maintained manually as static string literal.
566
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000567- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000568 and this cannot be converted to the required C type, an exception is
569 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000570 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000571
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000572- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000573 an exception.
574
Tim Peterscbdd3502006-09-05 01:47:53 +0000575- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000576 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000577 workarounds for clocks with low resolution, to stop the code yielding
578 duplicate UUIDs.
579
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000580- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
581 before raising SystemExit, allowing IDLE to honor quit() and exit().
582
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000583- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Fred Drake53912162006-07-29 13:22:49 +0000664What's New in Python 2.5 beta 3?
665================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000666
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000667*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000668
669Core and builtins
670-----------------
671
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000672- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000673 returned a long (see PEP 353).
674
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000675- Bug #1515471: string.replace() accepts character buffers again.
676
Neal Norwitz07aadb12006-07-30 06:55:48 +0000677- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
678 This provides the proper warning for struct.pack().
679 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
680
Neal Norwitz0d62a062006-07-30 06:53:31 +0000681- Patch #1531113: Fix augmented assignment with yield expressions.
682 Also fix a SystemError when trying to assign to yield expressions.
683
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000684- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
685 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
686 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
687 excessive filesystem operations during imports.
688
Tim Petersbc24eee2006-07-27 01:14:53 +0000689- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
690 operations on signed longs that are formally undefined by C.
691 Unfortunately, at least one compiler now cares about that, so complicated
692 the code to make that compiler happy again.
693
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000694- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
695
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000696- Patch #1232023: Stop including current directory in search
697 path on Windows.
698
Neal Norwitze1fdb322006-07-21 05:32:28 +0000699- Fix some potential crashes found with failmalloc.
700
Neal Norwitze7563102006-07-17 01:00:16 +0000701- Fix warnings reported by Klocwork's static analysis tool.
702
Neal Norwitz84be93b2006-07-16 01:50:38 +0000703- Bug #1512814, Fix incorrect lineno's when code within a function
704 had more than 255 blank lines.
705
Georg Brandl9dceedb2006-07-12 15:31:17 +0000706- Patch #1521179: Python now accepts the standard options ``--help`` and
707 ``--version`` as well as ``/?`` on Windows.
708
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000709- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000710 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000711 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000712
Tim Peters112aad32006-07-19 00:03:19 +0000713- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000714 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000715 new ``sys._current_frames()`` returns a dictionary with one entry,
716 mapping the faux "thread id" 0 to the current frame.
717
Ronald Oussoren3075e162006-07-25 20:28:55 +0000718- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000719

Neal Norwitza1f10902006-07-12 07:28:29 +0000721Library
722-------
723
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000724- Correction of patch #1455898: In the mbcs decoder, set final=False
725 for stream decoder, but final=True for the decode function.
726
Georg Brandl07fec3a2006-08-01 18:49:24 +0000727- os.urandom no longer masks unrelated exceptions like SystemExit or
728 KeyboardInterrupt.
729
Tim Peters4643c2f2006-08-10 22:45:34 +0000730- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000731 shutil.copytree on Windows
732
Georg Brandle34ac7c2006-07-30 11:07:23 +0000733- Bug #1002398: The documentation for os.path.sameopenfile now correctly
734 refers to file descriptors, not file objects.
735
Tim Peterscbdd3502006-09-05 01:47:53 +0000736- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000737 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000738 #1513611, and probably others.
739
Georg Brandledd9b0d2006-07-29 09:33:26 +0000740- Bug #1441397: The compiler module now recognizes module and function
741 docstrings correctly as it did in Python 2.4.
742
Tim Peters6f681472006-07-27 23:44:37 +0000743- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
744 lost that tests are sorted by name before being run. This rarely
745 matters for well-written tests, but can create baffling symptoms if
746 side effects from one test to the next affect outcomes. ``DocTestFinder``
747 has been changed to sort the list of tests it returns.
748
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000749- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000750 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000751
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000752- Bug #978833: Really close underlying socket in _socketobject.close.
753
Georg Brandldb232dc2006-08-20 13:15:43 +0000754- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
755 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000756
Georg Brandlcf0c1722006-07-26 07:23:32 +0000757- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
758 to recursive calls and call it with the failing package name.
759
Martin v. Löwis0b483032006-07-25 09:53:12 +0000760- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
761
Georg Brandlc13c34c2006-07-24 14:09:56 +0000762- Patch #1515343: Fix printing of deprecated string exceptions with a
763 value in the traceback module.
764
Greg Ward48fae7a2006-07-23 16:05:51 +0000765- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
766
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000767- Patch #1524429: Use repr() instead of backticks in Tkinter again.
768
Brett Cannoncaebe222006-07-18 04:41:36 +0000769- Bug #1520914: Change time.strftime() to accept a zero for any position in its
770 argument tuple. For arguments where zero is illegal, the value is forced to
771 the minimum value that is correct. This is to support an undocumented but
772 common way people used to fill in inconsequential information in the time
773 tuple pre-2.4.
774
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000775- Patch #1220874: Update the binhex module for Mach-O.
776
Barry Warsawb110bad2006-07-21 14:51:07 +0000777- The email package has improved RFC 2231 support, specifically for
778 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
779 (name*0=<blah>) parameter continuations. This may change the types of
780 values returned from email.message.Message.get_param() and friends.
781 Specifically in some cases where non-encoded continuations were used,
782 get_param() used to return a 3-tuple of (None, None, string) whereas now it
783 will just return the string (since non-encoded continuations don't have
784 charset and language parts).
785
786 Also, whereas % values were decoded in all parameter continuations, they are
787 now only decoded in encoded parameter parts.
788
Ronald Oussoren3075e162006-07-25 20:28:55 +0000789- Bug #1517990: IDLE keybindings on MacOS X now work correctly
790
791- Bug #1517996: IDLE now longer shows the default Tk menu when a
792 path browser, class browser or debugger is the frontmost window on MacOS X
793
Barry Warsaw00decd72006-07-27 23:43:15 +0000794- Patch #1520294: Support for getset and member descriptors in types.py,
795 inspect.py, and pydoc.py. Specifically, this allows for querying the type
796 of an object against these built-in types and more importantly, for getting
797 their docstrings printed in the interactive interpreter's help() function.

801-----------------
802
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000803- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
804 a socket operation on a socket with a timeout, the exception will be
805 caught correctly. Previously, the exception was not caught.
806
Thomas Heller1393d6a2006-07-28 21:43:20 +0000807- Patch #1529514: The _ctypes extension is now compiled on more
808 openbsd target platforms.
809
Tim Peters9cab5932006-07-28 00:30:00 +0000810- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
811 a memory leak, affecting pickles and deep copies.
812
Tim Petersbc24eee2006-07-27 01:14:53 +0000813- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000814 Paul Eggert.
815
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000816- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
817
Thomas Hellerce049a02006-07-14 17:51:14 +0000818- Patch #1521817: Index range checking on ctypes arrays containing
819 exactly one element enabled again. This allows iterating over these
820 arrays, without the need to check the array size before.
821
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000822- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000823 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000824 /dev/null in certain cases; this is now fixed.
825
Thomas Heller47d7a062006-07-12 08:43:47 +0000826- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
827 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000828
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000829- Because of a misspelled preprocessor symbol, ctypes was always
830 compiled without thread support; this is now fixed.
831
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000832- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
833 methods now allow their database parameter to be None as the
834 sleepycat API allows.
835
Matt Flemingec926502006-07-28 11:27:27 +0000836- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
837 bluetooth API compared with Linux and FreeBSD.
838
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000839Tests
840-----
841
842- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
843 how long the test file should take to play. Now accepts taking 2.93 secs
844 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
845
Georg Brandl4793aa32006-07-28 18:31:39 +0000846- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
847 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
848 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000855Mac
856---
857
858- PythonLauncher now works correctly when the path to the script contains
859 characters that are treated specially by the shell (such as quotes).
860
861- Bug #1527397: PythonLauncher now launches scripts with the working directory
862 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000863 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000864 expect.

872Core and builtins
873-----------------
874
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000875- Bug #1441486: The literal representation of -(sys.maxint - 1)
876 again evaluates to a int object, not a long.
877
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000878- Bug #1501934: The scope of global variables that are locally assigned
879 using augmented assignment is now correctly determined.
880
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000881- Bug #927248: Recursive method-wrapper objects can now safely
882 be released.
883
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000884- Bug #1417699: Reject locale-specific decimal point in float()
885 and atof().
886
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000887- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
888 omit a default "error" argument for NULL pointer. This allows
889 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000890
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000891- Bug #1519018: 'as' is now validated properly in import statements.
892
Neal Norwitz28746ab2006-07-09 22:14:42 +0000893- On 64 bit systems, int literals that use less than 64 bits are
894 now ints rather than longs.
895
Neal Norwitzed657552006-07-10 00:04:44 +0000896- Bug #1512814, Fix incorrect lineno's when code at module scope
897 started after line 256.
898
Tim Peters32a83612006-07-10 21:08:24 +0000899- New function ``sys._current_frames()`` returns a dict mapping thread
900 id to topmost thread stack frame. This is for expert use, and is
901 especially useful for debugging application deadlocks. The functionality
902 was previously available in Fazal Majid's ``threadframe`` extension
903 module, but it wasn't possible to do this in a wholly threadsafe way from

921
Thomas Woutersadd19112006-07-05 11:03:49 +0000922- string.Template() now correctly handles tuple-values. Previously,
923 multi-value tuples would raise an exception and single-value tuples would
924 be treated as the value they contain, instead.
925
Martin v. Löwisede77f52006-07-03 13:01:35 +0000926- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000936 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000937
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000938- Bug #1514703: Only setup canvas window in turtle when the canvas
939 is created.

Martin v. Löwis7596e832006-07-01 15:33:37 +0000941- Bug #1513223: .close() of a _socketobj now releases the underlying
942 socket again, which then gets closed as it becomes unreferenced.
943
Fred Drake10497c82006-06-29 02:57:48 +0000944- Bug #1504333: Make sgmllib support angle brackets in quoted
945 attribute values.
946
947- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
948 sgmllib ('[' and ']' were not accepted).
949
Georg Brandl1be63af2006-06-28 20:23:25 +0000950- Fix a bug in the turtle module's end_fill function.
951
Brett Cannon53ab5b72006-06-22 16:49:14 +0000952- Bug #1510580: The 'warnings' module improperly required that a Warning
953 category be either a types.ClassType and a subclass of Warning. The proper
954 check is just that it is a subclass with Warning as the documentation states.
955
Georg Brandlad29e632006-06-21 17:45:17 +0000956- The compiler module now correctly compiles the new try-except-finally
957 statement (bug #1509132).
958
Neal Norwitz60373cd2006-06-22 06:30:50 +0000959- The wsgiref package is now installed properly on Unix.
960
Vinay Sajip28e57612006-07-01 10:45:20 +0000961- A bug was fixed in logging.config.fileConfig() which caused a crash on
962 shutdown when fileConfig() was called multiple times.
963
Gerhard Häring762fbd32006-07-02 17:48:30 +0000964- The sqlite3 module did cut off data from the SQLite database at the first
965 null character before sending it to a custom converter. This has been fixed
966 now.
967
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000968Extension Modules
969-----------------
970
Tim Peters112aad32006-07-19 00:03:19 +0000971- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
972 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
973 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000974
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000975- Assigning None to pointer type fields in ctypes structures possible
976 overwrote the wrong fields, this is fixed now.
977
978- Fixed a segfault in _ctypes when ctypes.wintypes were imported
979 on non-Windows platforms.
980
981- Bug #1518190: The ctypes.c_void_p constructor now accepts any
982 integer or long, without range checking.
983
984- Patch #1517790: It is now possible to use custom objects in the ctypes
985 foreign function argtypes sequence as long as they provide a from_param
986 method, no longer is it required that the object is a ctypes type.
987
988- The '_ctypes' extension module now works when Python is configured
989 with the --without-threads option.
990
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000991- Bug #1513646: os.access on Windows now correctly determines write
992 access, again.
993
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000994- Bug #1512695: cPickle.loads could crash if it was interrupted with
995 a KeyboardInterrupt.
996
Neal Norwitza12aa882006-07-06 06:45:08 +0000997- Bug #1296433: parsing XML with a non-default encoding and
998 a CharacterDataHandler could crash the interpreter in pyexpat.
999
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001000- Patch #1516912: improve Modules support for OpenVMS.

1003-----
1004
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001005- Automate Windows build process for the Win64 SSL module.
1006
Tim Peters32a83612006-07-10 21:08:24 +00001007- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001008 Previously, the slight difference could cause compilation errors of the
1009 'zlib' module on systems with more than one version of zlib.
1010
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001011- The MSI compileall step was fixed to also support a TARGETDIR
1012 with spaces in it.
1013
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001014- Bug #1517388: sqlite3.dll is now installed on Windows independent
1015 of Tcl/Tk.
1016
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001017- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001018 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001020Tests
1021-----
1022
1023- Call os.waitpid() at the end of tests that spawn child processes in order
1024 to minimize resources (zombies).
1025
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001026Documentation
1027-------------
1028
Nick Coghlan2d792252006-07-06 13:47:18 +00001029- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1030 documentation for the warnings module.
1031
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001032- Patch #1509163: MS Toolkit Compiler no longer available.
1033
Neal Norwitz56640df2006-07-10 02:36:41 +00001034- Patch #1504046: Add documentation for xml.etree.

1042Core and builtins
1043-----------------
1044
Georg Brandla56b9152006-06-19 06:35:54 +00001045- Patch #1507676: Error messages returned by invalid abstract object operations
1046 (such as iterating over an integer) have been improved and now include the
1047 type of the offending object to help with debugging.
1048
Brett Cannonea3912b2006-06-13 21:46:41 +00001049- Bug #992017: A classic class that defined a __coerce__() method that returned
1050 its arguments swapped would infinitely recurse and segfault the interpreter.
1051
Neal Norwitz909eb122006-06-12 02:13:21 +00001052- Fix the socket tests so they can be run concurrently.
1053
Neal Norwitzb9845e72006-06-12 02:11:18 +00001054- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001055 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001056
Brett Cannon22565aa2006-06-09 22:31:23 +00001057- Bug #532646: object.__call__() will continue looking for the __call__
1058 attribute on objects until one without one is found. This leads to recursion
1059 when you take a class and set its __call__ attribute to an instance of the
1060 class. Originally fixed for classic classes, but this fix is for new-style.
1061 Removes the infinite_rec_3 crasher.
1062
Georg Brandl24250812006-06-09 18:45:48 +00001063- The string and unicode methods startswith() and endswith() now accept
1064 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1065
Brett Cannonde3b0522006-06-08 17:00:45 +00001066- Buffer objects, at the C level, never used the char buffer
1067 implementation even when the char buffer for the wrapped object was
1068 explicitly requested (originally returned the read or write buffer).
1069 Now a TypeError is raised if the char buffer is not present but is
1070 requested.
1071
Georg Brandlddbaa662006-06-04 21:56:52 +00001072- Patch #1346214: Statements like "if 0: suite" are now again optimized
1073 away like they were in Python 2.4.
1074
Georg Brandlb7c8f542006-05-27 12:30:25 +00001075- Builtin exceptions are now full-blown new-style classes instead of
1076 instances pretending to be classes, which speeds up exception handling
1077 by about 80% in comparison to 2.5a2.
1078
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001079- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1080 Unicode 4.1.
1081
Georg Brandlf4ef1162006-05-26 18:03:31 +00001082- Patch #921466: sys.path_importer_cache is now used to cache valid and
1083 invalid file paths for the built-in import machinery which leads to
1084 fewer open calls on startup.
1085
Tim Peters696cf432006-05-24 21:10:40 +00001086- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1087 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1088 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1089 the number of input digits (it was and remains linear-time for bases
1090 2, 4, 8, 16 and 32).
1091
Tim Petersb713ec22006-05-23 18:45:30 +00001092- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1093 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1094 an integer close to ``sys.maxint``. This was repaired by patch
1095 #1335972, which also gives a nice speedup.
1096
Richard Jonescebbefc2006-05-23 18:28:17 +00001097- Patch #1337051: reduced size of frame objects.
1098
1099- PyErr_NewException now accepts a tuple of base classes as its
1100 "base" parameter.
1101
Richard Jones7c88dcc2006-05-23 10:37:38 +00001102- Patch #876206: function call speedup by retaining allocated frame
1103 objects.
1104
Georg Brandl7b90e162006-05-18 07:01:27 +00001105- Bug #1462152: file() now checks more thoroughly for invalid mode
1106 strings and removes a possible "U" before passing the mode to the
1107 C library function.
1108
Neal Norwitz1004a532006-05-15 07:17:23 +00001109- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1110
Neal Norwitz373f0a72006-05-15 07:04:36 +00001111- Bug #1487966: Fix SystemError with conditional expression in assignment
1112
Martin v. Löwis879768d2006-05-11 13:28:43 +00001113- WindowsError now has two error code attributes: errno, which carries
1114 the error values from errno.h, and winerror, which carries the error
1115 values from winerror.h. Previous versions put the winerror.h values
1116 (from GetLastError()) into the errno attribute.
1117
Martin v. Löwis77736712006-05-04 05:51:03 +00001118- Patch #1475845: Raise IndentationError for unexpected indent.
1119
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001120- Patch #1479181: split open() and file() from being aliases for each other.
1121
Tim Peters44bd9862006-06-01 13:49:23 +00001122- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1123 methods were always silently ignored by dictionaries when comparing keys.
1124 They are now passed through (except when using the C API function
1125 ``PyDict_GetItem()``, whose semantics did not change).
1126
1127- Bug #1456209: In some obscure cases it was possible for a class with a
1128 custom ``__eq__()`` method to confuse dict internals when class instances
1129 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1130 No, you don't have any code that did this ;-)

1138
Brett Cannon6ee7d012006-06-08 16:23:04 +00001139- Change binascii.hexlify to accept a read-only buffer instead of only a char
1140 buffer and actually follow its documentation.
1141
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001142- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1143
Nick Coghlanc649ec52006-05-29 12:43:05 +00001144- Patch #1478788 (modified version): The functional extension module has
1145 been renamed to _functools and a functools Python wrapper module added.
1146 This provides a home for additional function related utilities that are
1147 not specifically about functional programming. See PEP 309.
1148
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001149- Patch #1493701: performance enhancements for struct module.

1154 copy() method.
1155
Andrew MacIntyre92913322006-06-13 15:04:24 +00001156- Patch #1454481: thread stack size is now tunable at runtime for thread
1157 enabled builds on Windows and systems with Posix threads support.
1158
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001159- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1160 (up to the system limit of 32K characters).
1161
1162- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1163 As a result, these functions now raise WindowsError instead of OSError.
1164
Tim Peters7a822da2006-05-25 21:50:17 +00001165- ``time.clock()`` on Win64 should use the high-performance Windows
1166 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1167 Windows platforms).
1168
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001169- Calling Tk_Init twice is refused if the first call failed as that
1170 may deadlock.
1171
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001172- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1173 accept it without potentially using an uninitialized pointer.
1174
1175- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1176 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1177 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +00001179- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001180 [pybsddb project SF patch number 1466734]
1181
Gregory P. Smith372b5832006-06-05 18:48:21 +00001182- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1183 parameter is supplied. [SF pybsddb bug #1477863]
1184
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001185- bsddb: the __len__ method of a DB object has been fixed to return correct
1186 results. It could previously incorrectly return 0 in some cases.
1187 Fixes SF bug 1493322 (pybsddb bug 1184012).
1188
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001189- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1190 aborts the db transaction safely when a modifier callback fails.
1191 Fixes SF python patch/bug #1408584.
1192
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001193- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001194 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001195 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1196 database calls that would previously deadlock. [SF python bug #775414]
1197

1220 mime.types file for determining MIME types.
1221
Georg Brandl2605ca82006-06-14 06:08:31 +00001222- Bug #1339007: Shelf objects now don't raise an exception in their
1223 __del__ method when initialization failed.
1224
Martin v. Löwisd8251432006-06-14 05:21:04 +00001225- Patch #1455898: The MBCS codec now supports the incremental mode for
1226 double-byte encodings.
1227
Tim Peters43898b42006-06-14 04:09:25 +00001228- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1229 guarantee that adjacent triples in the return list always describe
1230 non-adjacent blocks. Previously, a pair of matching blocks could end
1231 up being described by multiple adjacent triples that formed a partition
1232 of the matching pair.
1233
Greg Ward0e0c9f42006-06-11 16:24:11 +00001234- Bug #1498146: fix optparse to handle Unicode strings in option help,
1235 description, and epilog.
1236
Greg Wardd1c797e2006-06-11 14:42:41 +00001237- Bug #1366250: minor optparse documentation error.
1238
Greg Ward7f547402006-06-11 00:40:49 +00001239- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1240 clarify docs.
1241
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001242- The wsgiref package has been added to the standard library.
1243
Nick Coghlan676725d2006-06-08 13:54:49 +00001244- The functions update_wrapper() and wraps() have been added to the functools
1245 module. These make it easier to copy relevant metadata from the original
1246 function when writing wrapper functions.
1247
Tim Petersd6a9eef2006-06-05 01:48:21 +00001248- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1249 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001250
Martin v. Löwis3f767792006-06-04 19:36:28 +00001251- Patch #1359618: Speed up charmap encoder by using a trie structure
1252 for lookup.
1253
Tim Petersd609b1a2006-06-02 23:22:51 +00001254- The functions in the ``pprint`` module now sort dictionaries by key
1255 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1256 if and only if its display required more than one line, although that
1257 wasn't documented. The new behavior increases predictability; e.g.,
1258 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1259
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001260- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1262
Georg Brandl2b330372006-05-28 20:23:12 +00001263- Patch #1496206: improve urllib2 handling of passwords with respect to
1264 default HTTP and HTTPS ports.
1265

Bob Ippolito7298f272006-05-23 18:43:47 +00001268- Patch #1281707: speed up gzip.readline.
1269
Georg Brandlb89316f2006-05-17 15:51:16 +00001270- Patch #1180296: Two new functions were added to the locale module:
1271 format_string() to get the effect of "format % items" but locale-aware,
1272 and currency() to format a monetary number with currency sign.
1273
Georg Brandle3a25832006-05-17 14:56:04 +00001274- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1275 and several features added, such as speed and geometry control.
1276
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001277- Patch #1488881: add support for external file objects in bz2 compressed
1278 tarfiles.
1279
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001280- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1281 stdout arguments, making it possible to redirect input and output
1282 for remote debugging.
1283
1284- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1285 a couple of issues, notably handling of long file names using the
1286 GNU LONGNAME extension.
1287
1288- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1289 new flag when ``name`` is already the name of an option flag.
1290
1291- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1292 package.
1293
1294- Patch #1472854: make the rlcompleter.Completer class usable on non-
1295 UNIX platforms.
1296
1297- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1298
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001299- Bug #1472827: correctly escape newlines and tabs in attribute values in
1300 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001330What's New in Python 2.5 alpha 2?
1331=================================
1332
1333*Release date: 27-APR-2006*
1334
1335Core and builtins
1336-----------------
1337
Thomas Heller1b046642006-04-18 18:51:06 +00001338- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1339 by converting these apis from macros into exported functions again:
1340
1341 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1342 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1343 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1344 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1345 PyRun_String Py_CompileString
1346
Martin v. Löwis45294a92006-04-18 06:24:08 +00001347- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1348
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001349- All uses of PyStructSequence_InitType have been changed to initialize
1350 the type objects only once, even if the interpreter is initialized
1351 multiple times.
1352
Neal Norwitz61546162006-04-14 05:20:28 +00001353- Bug #1454485, array.array('u') could crash the interpreter. This was
1354 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1355 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1356
1357- Py_UNICODE is unsigned. It was always documented as unsigned, but
1358 due to a bug had a signed value in previous versions.
1359
Tim Peters3a5e8b12006-04-11 01:44:07 +00001360- Patch #837242: ``id()`` of any Python object always gives a positive
1361 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1362 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001363 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001364 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001365
Tim Peters3a5e8b12006-04-11 01:44:07 +00001366 def __hash__(self):
1367 return id(self) # WRONG
1368
1369 because a hash result must be a (short) Python int but it was always
1370 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001371 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001372 was always usable as a hash value before this patch. That's no longer
1373 necessarily so.
1374
1375- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001376 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001377 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001378 #1454844)
1379
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001380- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1381 involving generators that have paused outside of any ``try`` or ``with``
1382 blocks. (In 2.5a1, a paused generator that was part of a reference
1383 cycle could not be garbage collected, regardless of whether it was
1384 paused in a ``try`` or ``with`` block.)

1404 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001405
Armin Rigoa9017c32006-04-19 11:50:27 +00001406- Patch #1062014: AF_UNIX sockets under Linux have a special

1414 abusing errno.
1415
Tim Peters711bf302006-04-25 03:31:36 +00001416- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1417 a doctest to be skipped (the code is not run, and the expected output
1418 or exception is ignored).
1419
Nick Coghlanda2268f2006-04-24 04:37:15 +00001420- Fixed contextlib.nested to cope with exceptions being raised and
1421 caught inside exit handlers.
1422
Greg Wardab05edc2006-04-23 03:47:58 +00001423- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1424 hex, octal, or binary; add ``append_const`` action; keep going if
1425 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1426 added ``epilog`` for better help generation).
1427
Tim Peters21fbd572006-04-21 21:18:10 +00001428- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1429 called from a thread spawned as a side effect of importing a module.
1430
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001431- The pydoc module now supports documenting packages contained in
1432 .zip or .egg files.
1433
1434- The pkgutil module now has several new utility functions, such
1435 as ``walk_packages()`` to support working with packages that are either
1436 in the filesystem or zip files.
1437
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001438- The mailbox module can now modify and delete messages from
1439 mailboxes, in addition to simply reading them. Thanks to Gregory
1440 K. Johnson for writing the code, and to the 2005 Google Summer of
1441 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001442
Tim Petersc7605f22006-04-17 21:12:33 +00001443- The ``__del__`` method of class ``local`` in module ``_threading_local``
1444 returned before accomplishing any of its intended cleanup.
1445
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001446- Patch #790710: Add breakpoint command lists in pdb.

1454
Phillip J. Eby47032112006-04-11 01:07:43 +00001455- The warnings, linecache, inspect, traceback, site, and doctest modules

Anthony Baxter51bcb682006-04-05 14:51:42 +00001492Tests
1493-----
1494
Nick Coghlanda2268f2006-04-24 04:37:15 +00001495- test_contextlib now checks contextlib.nested can cope with exceptions
1496 being raised and caught inside exit handlers.

1499
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001500- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1501 it separately and by hand. It also wasn't cleaning up its changes to
1502 the current Decimal context.
1503
Thomas Woutersabd08882006-04-26 15:53:30 +00001504- regrtest.py now has a -M option to run tests that test the new limits of
1505 containers, on 64-bit architectures. Running these tests is only sensible
1506 on 64-bit machines with more than two gigabytes of memory. The argument
1507 passed is the maximum amount of memory for the tests to use.

1516-------------
1517
Tim Petersb06d28c2006-05-12 01:57:59 +00001518- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1519
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001520- PEP 343: Added Context Types section to the library reference
1521 and attempted to bring other PEP 343 related documentation into
1522 line with the implementation and/or python-dev discussions.
1523
Tim Peters8dc73d22006-04-24 02:03:16 +00001524- Bug #1337990: clarified that ``doctest`` does not support examples
1525 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001533Core and builtins
1534-----------------
1535
Nick Coghlan43832302006-04-23 17:04:07 +00001536- PEP 338: -m command line switch now delegates to runpy.run_module
1537 allowing it to support modules in packages and zipfiles
1538
Martin v. Löwisc661b882006-04-20 04:54:23 +00001539- On Windows, .DLL is not an accepted file name extension for
1540 extension modules anymore; extensions are only found if they
1541 end in .PYD.
1542
Martin v. Löwisea62d252006-04-03 10:56:49 +00001543- Bug #1421664: sys.stderr.encoding is now set to the same value as
1544 sys.stdout.encoding.
1545
Neal Norwitz92e212f2006-04-03 04:48:37 +00001546- __import__ accepts keyword arguments.
1547
Georg Brandlccadf842006-03-31 18:54:53 +00001548- Patch #1460496: round() now accepts keyword arguments.
1549
Anthony Baxter262c00a2006-03-30 10:53:17 +00001550- Fixed bug #1459029 - unicode reprs were double-escaped.
1551
Hye-Shik Changd478f342006-03-23 12:32:36 +00001552- Patch #1396919: The system scope threads are reenabled on FreeBSD
1553 5.4 and later versions.
1554
Neal Norwitze98ccf62006-03-23 05:39:47 +00001555- Bug #1115379: Compiling a Unicode string with an encoding declaration
1556 now gives a SyntaxError.
1557
Georg Brandlabd1ff82006-03-18 07:59:59 +00001558- Previously, Python code had no easy way to access the contents of a
1559 cell object. Now, a ``cell_contents`` attribute has been added
1560 (closes patch #1170323).
1561
Tim Peterscf79aac2006-03-16 01:14:46 +00001562- Patch #1123430: Python's small-object allocator now returns an arena to
1563 the system ``free()`` when all memory within an arena becomes unused
1564 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1565 freed. Some applications will see a drop in virtual memory size now,
1566 especially long-running applications that, from time to time, temporarily
1567 use a large number of small objects. Note that when Python returns an
1568 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001569 platform C library will in turn return that memory to the operating system.
1570 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001571 appears to be effective at least on Microsoft C and gcc-based systems.
1572 Thanks to Evan Jones for hard work and patience.
1573
Georg Brandl533ff6f2006-03-08 18:09:27 +00001574- Patch #1434038: property() now uses the getter's docstring if there is
1575 no "doc" argument given. This makes it possible to legitimately use
1576 property() as a decorator to produce a read-only property.
1577
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001578- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1579 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1580 of requiring an int or long in slicing and a few other contexts, enabling
1581 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1582
Neal Norwitz995acdf2006-03-07 05:01:00 +00001583- Fixed various bugs reported by Coverity's Prevent tool.
1584
Brett Cannonbf364092006-03-01 04:25:17 +00001585- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1586 new exception base class, BaseException, which has a new message attribute.
1587 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1588 Raising a string exception now raises a DeprecationWarning.
1589
Thomas Woutersfb609f42006-02-28 16:37:25 +00001590- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1591 explicitly relative, using 'from .module import name' to mean 'from the same
1592 package as this module is in. Imports without dots still default to the
1593 old relative-then-absolute, unless 'from __future__ import
1594 absolute_import' is used.
1595
Brett Cannona7446e32006-02-27 23:39:10 +00001596- Properly check if 'warnings' raises an exception (usually when a filter set
1597 to "error" is triggered) when raising a warning for raising string
1598 exceptions.
1599
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001600- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001601 The name was removed from Include/code.h.
1602
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001603- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001604
Guido van Rossum1968ad32006-02-25 22:38:04 +00001605- Patch 1433928:
1606 - The copy module now "copies" function objects (as atomic objects).
1607 - dict.__getitem__ now looks for a __missing__ hook before raising
1608 KeyError.
1609
Tim Peters84ef21c2006-02-28 20:39:06 +00001610- PEP 343: with statement implemented. Needs ``from __future__ import
1611 with_statement``. Use of 'with' as a variable will generate a warning.
1612 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001613 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001614 The following objects have __context__ methods:
1615 - The built-in file type.
1616 - The thread.LockType type.
1617 - The following types defined by the threading module:
1618 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1619 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001620
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001621- Fix the encodings package codec search function to only search
1622 inside its own package. Fixes problem reported in patch #1433198.
1623
1624 Note: Codec packages should implement and register their own
1625 codec search function. PEP 100 has the details.
1626
Tim Peters9ea89d22006-06-04 03:26:02 +00001627- PEP 353: Using ``Py_ssize_t`` as the index type.
1628
1629- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1630 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1631 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1632 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1633 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001634
Neal Norwitzfc76d632006-01-10 06:03:13 +00001635- Patch #1400181, fix unicode string formatting to not use the locale.
1636 This is how string objects work. u'%f' could use , instead of .
1637 for the decimal point. Now both strings and unicode always use periods.
1638
Neal Norwitz671b9e32006-01-09 07:07:12 +00001639- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1640 configure would break checking curses.h.
1641
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001642- Bug #959576: The pwd module is now builtin. This allows Python to be
1643 built on UNIX platforms without $HOME set.
1644
Neal Norwitzc10978f2005-12-19 06:07:16 +00001645- Bug #1072182, fix some potential problems if characters are signed.
1646
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001647- Bug #889500, fix line number on SyntaxWarning for global declarations.
1648
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001649- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1650
Neal Norwitze7214a12005-12-18 05:03:17 +00001651- Support for converting hex strings to floats no longer works.
1652 This was not portable. float('0x3') now raises a ValueError.
1653
Barry Warsaw2a38a862005-12-18 01:27:35 +00001654- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001655 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001656 is now displayed in interactive prompt banner.
1657
Georg Brandlfa166682005-12-17 21:45:17 +00001658- Implementation of PEP 341 - Unification of try/except and try/finally.
1659 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001660 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001661
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001662- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1663 now encodes backslash correctly.
1664
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001665- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1666
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001667- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001668 and long longs.
1669
Neal Norwitz67715f02005-11-09 06:59:35 +00001670- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001671 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001672 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001673
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001674- Replaced most Unicode charmap codecs with new ones using the
1675 new Unicode translate string feature in the builtin charmap
1676 codec; the codecs were created from the mapping tables available
1677 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1678 encodings now include a mapping for the Apple logo)
1679
Tim Peterse3547fd2005-12-16 23:13:57 +00001680- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001681
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001682- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001683
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001684- A new AST parser implementation was completed. The abstract
1685 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001686 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001687
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001688- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001689 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1690
Neal Norwitz708e51a2005-10-03 04:48:15 +00001691- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1692
Neal Norwitz11bd1192005-10-03 00:54:56 +00001693- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1694 Provide a warning when a directory is passed on the command line.
1695
Neal Norwitz40d37812005-10-02 01:48:49 +00001696- Fix segfault with invalid coding.
1697
1698- SF bug #772896: unknown encoding results in MemoryError.
1699
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001700- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001701 supported a __len__() method which evaluated to False when the iterator
1702 was empty.
1703
Guido van Rossum630db602005-09-20 18:49:54 +00001704- On 64-bit platforms, when __len__() returns a value that cannot be
1705 represented as a C int, raise OverflowError.
1706
Skip Montanarof8948ca2005-09-19 03:54:46 +00001707- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001708 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001709
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001710- SF bug #893549: parsing keyword arguments was broken with a few format
1711 codes.
1712
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001713- Changes donated by Elemental Security to make it work on AIX 5.3
1714 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1715 bug #105470: test_pwd fails on 64bit system (Opteron).
1716
Guido van Rossum539c6622005-09-14 17:49:54 +00001717- Changes donated by Elemental Security to make it work on HP-UX 11 on
1718 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1719
Georg Brandl4550b8d2005-08-26 06:43:52 +00001720- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001721 (fixes bug #1119418).
1722
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001723- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1724
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001725- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1726 exceptions that cause a function to exit.
1727
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001728- The implementation of set() and frozenset() was revised to use its
1729 own internal data structure. Memory consumption is reduced by 1/3
1730 and there are modest speed-ups as well. The API is unchanged.
1731
Tim Petersde7990b2005-07-17 23:45:23 +00001732- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1733
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001734- SF bug #1229429: PyObject_CallMethod failed to decrement some
1735 reference counts in some error exit cases.
1736
Tim Petersecc6e6a2005-07-10 22:30:55 +00001737- SF bug #1185883: Python's small-object memory allocator took over
1738 a block managed by the platform C library whenever a realloc specified
1739 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001740 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001741 portable way to copy data from the C-managed block into Python's
1742 small-object space without risking a memory fault. Python's small-object
1743 realloc now leaves such blocks under the control of the platform C
1744 realloc.
1745
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001746- SF bug #1232517: An overflow error was not detected properly when
1747 attempting to convert a large float to an int in os.utime().
1748
Raymond Hettinger3296e692005-06-29 23:29:56 +00001749- SF bug #1224347: hex longs now print with lowercase letters just
1750 like their int counterparts.
1751
Michael W. Hudson188d4362005-06-20 16:52:57 +00001752- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1753 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1754 interpreter states; back out that fix and do a better job (see
1755 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1756 for a longer write-up of the problem).
1757
Michael W. Hudsondf888462005-06-03 14:41:55 +00001758- SF patch #1180995: marshal now uses a binary format by default when
1759 serializing floats.
1760
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001761- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1762 the routines that promise to produce IEEE 754 binary representations
1763 of floats now simply copy bytes around.
1764
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001765- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1766 278.
1767
Brett Cannonc3647ac2005-04-26 03:45:26 +00001768- patch #1109424: int, long, float, complex, and unicode now check for the
1769 proper magic slot for type conversions when subclassed. Previously the
1770 magic slot was ignored during conversion. Semantics now match the way
1771 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001772 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001773 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001774 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001775
Barry Warsawc8d907c2005-04-19 23:43:40 +00001776- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1777 NULL, now raise an AttributeError when attempting to set or delete the
1778 attribute. Previously a TypeError was raised, but this was inconsistent
1779 with the equivalent pure-Python implementation.
1780
Michael W. Hudson774479c2005-04-18 08:46:17 +00001781- It is now safe to call PyGILState_Release() before
1782 PyEval_InitThreads() (note that if there is reason to believe there
1783 are multiple threads around you still must call PyEval_InitThreads()
1784 before using the Python API; this fix is for extension modules that
1785 have no way of knowing if Python is multi-threaded yet).
1786
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001787- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1788 disabled caused a crash.
1789
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001790- Bug #1165306: instancemethod_new allowed the creation of a method
1791 with im_class == im_self == NULL, which caused a crash when called.
1792
Tim Petersecc6e6a2005-07-10 22:30:55 +00001793- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001794 fixes the crash seen in bug #1165761
1795
Raymond Hettinger96229b12005-03-11 06:49:40 +00001796- Added two new builtins, any() and all().
1797
Brett Cannon409d8f22005-03-05 06:47:57 +00001798- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001799 (e.g., ``class C(): pass`` is no longer a syntax error).
1800 Patch #1176012 added support to the 'parser' module and 'compiler' package
1801 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001802

1806 returning None.
1807
Tim Petersecc6e6a2005-07-10 22:30:55 +00001808- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001809 ('\') with a specific error message.
1810
Martin v. Löwisff232d72005-03-03 09:24:38 +00001811- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1812
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001813- Bug #1124295: the __name__ attribute of file objects was

1815
Tim Petersecc6e6a2005-07-10 22:30:55 +00001816- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001817 an ferror() call.
1818
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001819- min() and max() now support key= arguments with the same meaning as in
1820 list.sort().
1821
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001822- The peephole optimizer now performs simple constant folding in expressions:
1823 (2+3) --> (5).
1824
Raymond Hettingera422c342005-01-11 03:03:27 +00001825- set and frozenset objects can now be marshalled. SF #1098985.
1826
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001827- Bug #1077106: Poor argument checking could cause memory corruption
1828 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001829
Jeremy Hyltonab630502005-02-04 18:44:06 +00001830- The parser did not complain about future statements in illegal
1831 positions. It once again reports a syntax error if a future
1832 statement occurs after anything other than a doc string.
1833
Neil Schemenauercf52c072005-08-12 17:34:58 +00001834- Change the %s format specifier for str objects so that it returns a
1835 unicode instance if the argument is not an instance of basestring and
1836 calling __str__ on the argument returns a unicode instance.
1837
Tim Petersf4e69282006-02-27 17:15:31 +00001838- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1839 current thread state when the auto-GIL-state machinery knows about
1840 it (since the thread state is being deleted, continuing to remember it
1841 can't help, but can hurt if another thread happens to get created with
1842 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002038- PEP 338: new module runpy defines a run_module function to support
2039 executing modules which provide access to source code or a code object
2040 via the PEP 302 import mechanisms.
2041
Anthony Baxter93f5b932006-04-03 08:05:07 +00002042- The email module's parsedate_tz function now sets the daylight savings

2050 in attribute values.
2051
Anthony Baxterc51ee692006-04-01 00:57:31 +00002052- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002053 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002054 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002055 module will not be built.
2056
Tim Petersc17976e2006-04-01 00:26:53 +00002057- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2058 aren't officially supported here, and trying to use them will probably
2059 raise an exception some day. But dicts have been allowed, and "mostly
2060 worked", so support for them won't go away without warning.
2061
Georg Brandl338ef7d2006-03-31 18:42:16 +00002062- Bug #1445068: getpass.getpass() can now be given an explicit stream

2074 to make it easier to monitor when daemon threads have completed
2075 processing all enqueued tasks. Patch #1455676.
2076
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002077- popen2.Popen objects now preserve the command in a .cmd attribute.

2080
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002081- email 4.0 package now integrated. This is largely the same as the email 3.0
2082 package that was included in Python 2.3, except that PEP 8 module names are
2083 now used (e.g. mail.message instead of email.Message). The MIME classes
2084 have been moved to a subpackage (e.g. email.mime.text instead of
2085 email.MIMEText). The old names are still supported for now. Several
2086 deprecated Message methods have been removed and lots of bugs have been
2087 fixed. More details can be found in the email package documentation.
2088
Walter Dörwald40108c92006-03-27 08:15:44 +00002089- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2090 (a subclass of tuple) that provides incremental decoders and encoders
2091 (a way to use stateful codecs without the stream API). Python functions
2092 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2093 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2094 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002095
Walter Dörwald067db482006-03-15 22:17:27 +00002096- Patch #1359365: Calling next() on a closed StringIO.String object raises
2097 a ValueError instead of a StopIteration now (like file and cString.String do).
2098 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2099 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002100

2174 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2175 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2176 Ronald L. Rivest offered this advice for Python:
2177
2178 "The consensus of researchers in this area (at least as
2179 expressed at the NIST Hash Function Workshop 10/31/05),
2180 is that SHA-256 is a good choice for the time being, but
2181 that research should continue, and other alternatives may
2182 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002183
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002184- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger267b8682005-03-27 10:47:39 +00002300- decimal operator and comparison methods now return NotImplemented
2301 instead of raising a TypeError when interacting with other types. This
2302 allows other classes to implement __radd__ style methods and have them
2303 work as expected.
2304
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002305- Bug #1163325: Decimal infinities failed to hash. Attempting to
2306 hash a NaN raised an InvalidOperation instead of a TypeError.
2307
Tim Petersecc6e6a2005-07-10 22:30:55 +00002308- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002309 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2310
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002311- Patch #1043890: Add extractall method to tarfile.
2312
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002313- Patch #1075887: Don't require MSVC in distutils if there is nothing
2314 to build.
2315
Martin v. Löwis637431b2005-03-03 23:12:42 +00002316- Patch #1103407: Properly deal with tarfile iterators when untarring
2317 symbolic links on Windows.
2318
Tim Petersecc6e6a2005-07-10 22:30:55 +00002319- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002320 profile.py if available.
2321
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002322- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2323
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002324- Patch #1117454: Remove code to special-case cookies without values
2325 in LWPCookieJar.
2326
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002327- Patch #1117339: Add cookielib special name tests.
2328
Martin v. Löwise869eb12005-03-03 09:46:07 +00002329- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2330
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002331- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2332
Martin v. Löwisdf241532005-03-03 08:17:42 +00002333- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2334
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002335- Patch #1104111: Alter setup.py --help and --help-commands.
2336
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002337- Patch #1121234: Properly cleanup _exit and tkerror commands.
2338
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002339- Patch #1049151: xdrlib now unpacks booleans as True or False.
2340
Raymond Hettingerbab41432005-02-05 01:31:19 +00002341- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2342
Guido van Rossumd0641422005-02-03 15:01:24 +00002343- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2344 disables recursive traversal through instance attributes, which can
2345 be exploited in various ways.
2346
Tim Peterse3547fd2005-12-16 23:13:57 +00002347- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002348 flags on the HTTP listening socket.
2349
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002350- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2351 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2352
Fred Drakefbdeaad2006-07-29 16:56:15 +00002353- Patches #893642, #1039083: add allow_none, encoding arguments to
2354 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002355
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002356- Bug #1110478: Revert os.environ.update to do putenv again.
2357
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002358- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2359
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002360- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2361
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002362- Enhancements to the csv module:
2363
2364 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002365 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002366 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002367 + Dialect parameter parsing has been re-implemented to improve error
2368 reporting.
2369 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2370 dictates.
2371 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002372 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002373 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002374 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2375 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002376 + reader now allows \r characters to be quoted (previously it only allowed
2377 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002378 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002379 + Dialect classes passed to the module are no longer instantiated by
2380 the module before being parsed (the former validation scheme required
2381 this, but the mechanism was unreliable).
2382 + The dialect registry now contains instances of the internal
2383 C-coded dialect type, rather than references to python objects.
2384 + the internal c-coded dialect type is now immutable.
2385 + register_dialect now accepts the same keyword dialect specifications
2386 as the reader and writer, allowing the user to register dialects
2387 without first creating a dialect class.
2388 + a configurable limit to the size of parsed fields has been added -
2389 previously, an unmatched quote character could result in the entire
2390 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002391 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002392 the parser field size limit (returning the former limit). The initial
2393 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002394 + A line_num attribute has been added to the reader object, which tracks
2395 the number of lines read from the source iterator. This is not
2396 the same as the number of records returned, as records can span
2397 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002398 + reader and writer objects were not being registered with the cyclic-GC.
2399 This has been fixed.
2400
Brett Cannone6539c42005-01-08 02:43:53 +00002401- _DummyThread objects in the threading module now delete self.__block that is
2402 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2403 lock primitives tend to be limited in number and thus should not be wasted on
2404 a _DummyThread object. Fixes bug #1089632.
2405
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002406- The imghdr module now detects Exif files.
2407
Raymond Hettinger6065d322004-12-20 23:51:53 +00002408- StringIO.truncate() now correctly adjusts the size attribute.
2409 (Bug #951915).
2410
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002411- locale.py now uses an updated locale alias table (built using
2412 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2413 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002414 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002415
Raymond Hettinger3557f422004-12-07 12:02:02 +00002416- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2417
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002418- the pickle module no longer accepts the deprecated None option in the
2419 args tuple returned by __reduce__().
2420
Brett Cannon84667c02004-12-07 03:25:18 +00002421- optparse now optionally imports gettext. This allows its use in setup.py.
2422
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002423- the pickle module no longer uses the deprecated bin parameter.
2424
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002425- the shelve module no longer uses the deprecated binary parameter.
2426
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002427- the pstats module no longer uses the deprecated ignore() method.
2428
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002429- the filecmp module no longer uses the deprecated use_statcache argument.
2430
Raymond Hettinger664347b2004-12-04 21:21:53 +00002431- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2432 extended or overridden by subclasses. Formerly, the subclassed method would
2433 be ignored by the rest of the module. (Bug #1078905).
2434
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002435- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002436 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002437
Walter Dörwald36733692004-12-22 12:50:50 +00002438- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2439 once when a size argument is given. This prevents a buffer overflow in the
2440 tokenizer with very long source lines.
2441
Barry Warsaw538561e2006-01-01 21:48:54 +00002442- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2443 immediately after creating the object, without any intervening
2444 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002445
Skip Montanaro05885812005-01-16 20:48:27 +00002446- The reconvert.quote function can now emit triple-quoted strings. The
2447 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002448
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002449- ``UserString.MutableString`` now supports negative indices in
2450 ``__setitem__`` and ``__delitem__``
2451
Greg Ward40407942005-03-05 02:53:17 +00002452- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2453 correctly.
2454
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002455- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2456 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2457 character even if the user has passed a size parameter to get a proper
2458 line ending. Remove the special handling of a "\r\n" that has been split
2459 between two lines.
2460
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002461- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2462 about illegal code points. The codec now supports PEP 293 style error
2463 handlers.
2464
Walter Dörwald78a78b02005-09-01 12:04:29 +00002465- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002466 from the input stream, so that the output is a byte string in the correct
2467 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002468
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002469- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2470 considering it exactly like a '*'.
2471
Walter Dörwald007f8df2005-10-09 19:42:27 +00002472- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2473 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002474
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002475- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2476
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002477- Patch #1413711: Certain patterns of differences were making difflib
2478 touch the recursion limit.
2479
Walter Dörwald58917a62006-03-31 15:26:22 +00002480- Bug #947906: An object oriented interface has been added to the calendar
2481 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002482 called as a script (e.g. via ``python -mcalendar``). Localized month and
2483 weekday names can be ouput (even if an exotic encoding is used) using
2484 special classes that use unicode.

2487-----
2488
Neal Norwitz602d3392006-03-31 08:21:40 +00002489- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2490 by using -mieee gcc option.
2491
Martin v. Löwis86d66262006-02-17 08:40:11 +00002492- Patch #1432345: Make python compile on DragonFly.
2493
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002494- Build support for Win64-AMD64 was added.
2495
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002496- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2497
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002498- Patch #881820: look for openpty and forkpty also in libbsd.
2499
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002500- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2501 The zlib module is now builtin on Windows.
2502
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002503- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2504
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002505- Bug #1189330: configure did not correctly determine the necessary
2506 value of LINKCC if python was built with GCC 4.0.
2507
Trent Mick8321b422005-07-26 02:29:21 +00002508- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2509 vulnerability in zlib 1.2.1 and 1.2.2.
2510
Brett Cannon08cd5982005-04-24 22:26:38 +00002511- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2512 flags that change binary compatibility. Changes were also made to
2513 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002514 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002515
Bob Ippolitoed233462005-03-29 13:47:59 +00002516- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2517 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2518 no longer exists). This configure patch makes things right.
2519
Martin v. Löwise2713be2005-03-08 15:03:08 +00002520- Bug #1158607: Build with --disable-unicode again.
2521
Brett Cannon46d96232005-02-16 00:07:19 +00002522- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2523 defined. Discovered as a result of not being able to build on OS X.
2524
Brett Cannon516592f2004-12-07 00:42:59 +00002525- setup.py now uses the directories specified in LDFLAGS using the -L option
2526 and in CPPFLAGS using the -I option for adding library and include
2527 directories, respectively, for compiling extension modules against. This has
2528 led to the core being compiled using the values in CPPFLAGS. It also removes
2529 the need for the special-casing of both DarwinPorts and Fink for darwin since
2530 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2531 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2532 Fink, ``-I/opt/local/include`` for DarwinPorts).
2533
Brett Cannon43802422005-02-10 20:48:03 +00002534- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2535 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2536 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2537 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002539C API
2540-----
2541
Tim Petersc9d78aa2006-03-26 23:27:58 +00002542- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2543 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2544 is obtained via the ``PyObject_`` family, it must be released via the
2545 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2546 always been officially true, but when Python's small-object allocator was
2547 introduced, an attempt was made to cater to a few extension modules
2548 discovered at the time that obtained memory via ``PyObject_New`` but
2549 released it via ``PyMem_DEL``. It's years later, and if such code still
2550 exists it will fail now (probably with segfaults, but calling wrong
2551 low-level memory management functions can yield many symptoms).
2552
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002553- Added a C API for set and frozenset objects.
2554
Raymond Hettinger66517482004-12-03 11:45:13 +00002555- Removed PyRange_New().
2556
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002557- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2558 mapping argument now. This string is used as a mapping table. Byte values
2559 greater than the length of the string and 0xFFFE are treated as undefined
2560 mappings.
