567
Brett Cannon19d76c52006-09-09 07:18:44 +0000568- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

704Core and builtins
705-----------------
706
Neal Norwitz24b6f202006-09-05 04:43:56 +0000707- Fix infinite recursion when subclassing long and overriding __hash__.
708
709- Fix concatenation (+=) of long strings.
710
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000711- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000712 compared equal or unequal to a string and a UnicodeDecodeError
713 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000714
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000715 Instead, the equal (==) and unequal (!=) comparison operators will
716 now issue a UnicodeWarning and interpret the two objects as
717 unequal. The UnicodeWarning can be filtered as desired using
718 the warning framework, e.g. silenced completely, turned into an
719 exception, logged, etc.
720
721 Note that compare operators other than equal and unequal will still
722 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000723
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000724- Fix segfault when doing string formatting on subclasses of long.
725
726- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
727 with new-style classes.
728
729- Fix bug related to __len__ functions returning negative values with
730 classic classes.
731
732- Patch #1538606, Fix __index__() clipping. There were some problems
733 discovered with the API and how integers that didn't fit into Py_ssize_t
734 were handled. This patch attempts to provide enough alternatives
735 to effectively use __index__.
736
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000737- Bug #1536021: __hash__ may now return long int; the final hash
738 value is obtained by invoking hash on the long int.
739
Thomas Hellerab1049c2006-08-08 17:37:00 +0000740- Bug #1536786: buffer comparison could emit a RuntimeWarning.
741
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000742- Bug #1535165: fixed a segfault in input() and raw_input() when
743 sys.stdin is closed.
744
Thomas Heller74d36f02006-08-04 18:17:40 +0000745- On Windows, the PyErr_Warn function is now exported from
746 the Python dll again.
747
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000748- Bug #1191458: tracing over for loops now produces a line event
749 on each iteration. Fixing this problem required changing the .pyc
750 magic number. This means that .pyc files generated before 2.5c1
751 will be regenerated.
752
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000753- Bug #1333982: string/number constants were inappropriately stored
754 in the byte code and co_consts even if they were not used, ie
755 immediately popped off the stack.
756
Georg Brandle9462c72006-08-04 18:03:37 +0000757- Fixed a reference-counting problem in property().

760Library
761-------
762
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000763- Fix a bug in the ``compiler`` package that caused invalid code to be
764 generated for generator expressions.
765
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000766- The distutils version has been changed to 2.5.0. The change to
767 keep it programmatically in sync with the Python version running
768 the code (introduced in 2.5b3) has been reverted. It will continue
769 to be maintained manually as static string literal.
770
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000771- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000772 and this cannot be converted to the required C type, an exception is
773 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000774 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000775
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000776- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000777 an exception.
778
Tim Peterscbdd3502006-09-05 01:47:53 +0000779- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000780 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000781 workarounds for clocks with low resolution, to stop the code yielding
782 duplicate UUIDs.
783
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000784- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
785 before raising SystemExit, allowing IDLE to honor quit() and exit().
786
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000787- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
788
Georg Brandl7a1af772006-08-14 21:55:28 +0000789- Patch #1536071: trace.py should now find the full module name of a
790 file correctly even on Windows.
791
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000792- logging's atexit hook now runs even if the rest of the module has
793 already been cleaned up.
794
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000795- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000796
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000797- Bug #1531405, format_exception no longer raises an exception if
798 str(exception) raised an exception.
799
Neil Schemenauer06ded092006-08-04 16:20:30 +0000800- Fix a bug in the ``compiler`` package that caused invalid code to be
801 generated for nested functions.

812 raises the correct exceptions.
813
Thomas Heller1ce433e2006-08-14 16:20:04 +0000814- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
815 '-no-stack-protector' compiler flag for OpenBSD has been removed.
816
Thomas Heller86720042006-08-14 11:17:48 +0000817- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
818 uses the _as_parameter_ attribute when objects are passed to foreign
819 function calls. The ctypes version number was changed to 1.0.1.
820
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000821- Bug #1530559, struct.pack raises TypeError where it used to convert.
822 Passing float arguments to struct.pack when integers are expected
823 now triggers a DeprecationWarning.
824
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000825

873Core and builtins
874-----------------
875
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000876- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000877 returned a long (see PEP 353).
878
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000879- Bug #1515471: string.replace() accepts character buffers again.
880
Neal Norwitz07aadb12006-07-30 06:55:48 +0000881- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
882 This provides the proper warning for struct.pack().
883 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
884
Neal Norwitz0d62a062006-07-30 06:53:31 +0000885- Patch #1531113: Fix augmented assignment with yield expressions.
886 Also fix a SystemError when trying to assign to yield expressions.
887
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000888- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
889 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
890 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
891 excessive filesystem operations during imports.
892
Tim Petersbc24eee2006-07-27 01:14:53 +0000893- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
894 operations on signed longs that are formally undefined by C.
895 Unfortunately, at least one compiler now cares about that, so complicated
896 the code to make that compiler happy again.
897
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000898- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
899
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000900- Patch #1232023: Stop including current directory in search

Neal Norwitz84be93b2006-07-16 01:50:38 +0000907- Bug #1512814, Fix incorrect lineno's when code within a function
908 had more than 255 blank lines.
909
Georg Brandl9dceedb2006-07-12 15:31:17 +0000910- Patch #1521179: Python now accepts the standard options ``--help`` and
911 ``--version`` as well as ``/?`` on Windows.
912
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000913- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000914 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000915 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000916
Tim Peters112aad32006-07-19 00:03:19 +0000917- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000918 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000919 new ``sys._current_frames()`` returns a dictionary with one entry,
920 mapping the faux "thread id" 0 to the current frame.
921
Ronald Oussoren3075e162006-07-25 20:28:55 +0000922- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

926-------
927
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000928- Correction of patch #1455898: In the mbcs decoder, set final=False
929 for stream decoder, but final=True for the decode function.
930
Georg Brandl07fec3a2006-08-01 18:49:24 +0000931- os.urandom no longer masks unrelated exceptions like SystemExit or
932 KeyboardInterrupt.
933
Tim Peters4643c2f2006-08-10 22:45:34 +0000934- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000935 shutil.copytree on Windows
936
Georg Brandle34ac7c2006-07-30 11:07:23 +0000937- Bug #1002398: The documentation for os.path.sameopenfile now correctly
938 refers to file descriptors, not file objects.
939
Tim Peterscbdd3502006-09-05 01:47:53 +0000940- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000941 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000942 #1513611, and probably others.
943
Georg Brandledd9b0d2006-07-29 09:33:26 +0000944- Bug #1441397: The compiler module now recognizes module and function
945 docstrings correctly as it did in Python 2.4.
946
Tim Peters6f681472006-07-27 23:44:37 +0000947- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
948 lost that tests are sorted by name before being run. This rarely
949 matters for well-written tests, but can create baffling symptoms if
950 side effects from one test to the next affect outcomes. ``DocTestFinder``
951 has been changed to sort the list of tests it returns.
952
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000953- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000954 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000955
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000956- Bug #978833: Really close underlying socket in _socketobject.close.
957
Georg Brandldb232dc2006-08-20 13:15:43 +0000958- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
959 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000960
Georg Brandlcf0c1722006-07-26 07:23:32 +0000961- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
962 to recursive calls and call it with the failing package name.
963
Martin v. Löwis0b483032006-07-25 09:53:12 +0000964- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
965
Georg Brandlc13c34c2006-07-24 14:09:56 +0000966- Patch #1515343: Fix printing of deprecated string exceptions with a
967 value in the traceback module.
968
Greg Ward48fae7a2006-07-23 16:05:51 +0000969- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
970
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000971- Patch #1524429: Use repr() instead of backticks in Tkinter again.
972
Brett Cannoncaebe222006-07-18 04:41:36 +0000973- Bug #1520914: Change time.strftime() to accept a zero for any position in its
974 argument tuple. For arguments where zero is illegal, the value is forced to
975 the minimum value that is correct. This is to support an undocumented but
976 common way people used to fill in inconsequential information in the time
977 tuple pre-2.4.
978
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000979- Patch #1220874: Update the binhex module for Mach-O.
980
Barry Warsawb110bad2006-07-21 14:51:07 +0000981- The email package has improved RFC 2231 support, specifically for
982 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
983 (name*0=<blah>) parameter continuations. This may change the types of
984 values returned from email.message.Message.get_param() and friends.
985 Specifically in some cases where non-encoded continuations were used,
986 get_param() used to return a 3-tuple of (None, None, string) whereas now it
987 will just return the string (since non-encoded continuations don't have
988 charset and language parts).
989
990 Also, whereas % values were decoded in all parameter continuations, they are
991 now only decoded in encoded parameter parts.
992
Ronald Oussoren3075e162006-07-25 20:28:55 +0000993- Bug #1517990: IDLE keybindings on MacOS X now work correctly
994
995- Bug #1517996: IDLE now longer shows the default Tk menu when a
996 path browser, class browser or debugger is the frontmost window on MacOS X
997
Barry Warsaw00decd72006-07-27 23:43:15 +0000998- Patch #1520294: Support for getset and member descriptors in types.py,
999 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1000 of an object against these built-in types and more importantly, for getting
1001 their docstrings printed in the interactive interpreter's help() function.

1005-----------------
1006
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001007- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1008 a socket operation on a socket with a timeout, the exception will be
1009 caught correctly. Previously, the exception was not caught.
1010
Thomas Heller1393d6a2006-07-28 21:43:20 +00001011- Patch #1529514: The _ctypes extension is now compiled on more
1012 openbsd target platforms.
1013
Tim Peters9cab5932006-07-28 00:30:00 +00001014- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1015 a memory leak, affecting pickles and deep copies.
1016
Tim Petersbc24eee2006-07-27 01:14:53 +00001017- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001018 Paul Eggert.
1019
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001020- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1021
Thomas Hellerce049a02006-07-14 17:51:14 +00001022- Patch #1521817: Index range checking on ctypes arrays containing
1023 exactly one element enabled again. This allows iterating over these
1024 arrays, without the need to check the array size before.
1025
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001026- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001027 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001028 /dev/null in certain cases; this is now fixed.
1029
Thomas Heller47d7a062006-07-12 08:43:47 +00001030- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1031 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001032
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001033- Because of a misspelled preprocessor symbol, ctypes was always
1034 compiled without thread support; this is now fixed.
1035
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001036- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1037 methods now allow their database parameter to be None as the
1038 sleepycat API allows.
1039
Matt Flemingec926502006-07-28 11:27:27 +00001040- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1041 bluetooth API compared with Linux and FreeBSD.
1042
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001043Tests
1044-----
1045
1046- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1047 how long the test file should take to play. Now accepts taking 2.93 secs
1048 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1049
Georg Brandl4793aa32006-07-28 18:31:39 +00001050- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1051 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1052 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001059Mac
1060---
1061
1062- PythonLauncher now works correctly when the path to the script contains
1063 characters that are treated specially by the shell (such as quotes).
1064
1065- Bug #1527397: PythonLauncher now launches scripts with the working directory
1066 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001067 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001068 expect.

1077-----------------
1078
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001079- Bug #1441486: The literal representation of -(sys.maxint - 1)
1080 again evaluates to a int object, not a long.
1081
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001082- Bug #1501934: The scope of global variables that are locally assigned
1083 using augmented assignment is now correctly determined.
1084
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001085- Bug #927248: Recursive method-wrapper objects can now safely
1086 be released.
1087
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001088- Bug #1417699: Reject locale-specific decimal point in float()
1089 and atof().
1090
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001091- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1092 omit a default "error" argument for NULL pointer. This allows
1093 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001094
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001095- Bug #1519018: 'as' is now validated properly in import statements.
1096
Neal Norwitz28746ab2006-07-09 22:14:42 +00001097- On 64 bit systems, int literals that use less than 64 bits are
1098 now ints rather than longs.
1099
Neal Norwitzed657552006-07-10 00:04:44 +00001100- Bug #1512814, Fix incorrect lineno's when code at module scope
1101 started after line 256.
1102
Tim Peters32a83612006-07-10 21:08:24 +00001103- New function ``sys._current_frames()`` returns a dict mapping thread
1104 id to topmost thread stack frame. This is for expert use, and is
1105 especially useful for debugging application deadlocks. The functionality
1106 was previously available in Fazal Majid's ``threadframe`` extension
1107 module, but it wasn't possible to do this in a wholly threadsafe way from
1108 an extension.

1114 VS 2003.
1115
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001116- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1117
Tim Peters32a83612006-07-10 21:08:24 +00001118- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001119 environment variable to be set in order to the SDK environment
1120 for finding the compiler, include files, etc.
1121
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001122- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1123
Nick Coghlan2d792252006-07-06 13:47:18 +00001124- warnings.py now ignores ImportWarning by default
1125
Thomas Woutersadd19112006-07-05 11:03:49 +00001126- string.Template() now correctly handles tuple-values. Previously,
1127 multi-value tuples would raise an exception and single-value tuples would
1128 be treated as the value they contain, instead.
1129
Martin v. Löwisede77f52006-07-03 13:01:35 +00001130- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1131 even if some data are received.
1132
Martin v. Löwis45482392006-07-03 12:28:58 +00001133- Bug #1267547: Put proper recursive setup.py call into the
1134 spec file generated by bdist_rpm.
1135
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001136- Bug #1514693: Update turtle's heading when switching between
1137 degrees and radians.
1138
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001139- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001140 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001141
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001142- Bug #1514703: Only setup canvas window in turtle when the canvas
1143 is created.
1144
Martin v. Löwis7596e832006-07-01 15:33:37 +00001145- Bug #1513223: .close() of a _socketobj now releases the underlying
1146 socket again, which then gets closed as it becomes unreferenced.
1147
Fred Drake10497c82006-06-29 02:57:48 +00001148- Bug #1504333: Make sgmllib support angle brackets in quoted
1149 attribute values.
1150
1151- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1152 sgmllib ('[' and ']' were not accepted).
1153
Georg Brandl1be63af2006-06-28 20:23:25 +00001154- Fix a bug in the turtle module's end_fill function.
1155
Brett Cannon53ab5b72006-06-22 16:49:14 +00001156- Bug #1510580: The 'warnings' module improperly required that a Warning
1157 category be either a types.ClassType and a subclass of Warning. The proper
1158 check is just that it is a subclass with Warning as the documentation states.
1159
Georg Brandlad29e632006-06-21 17:45:17 +00001160- The compiler module now correctly compiles the new try-except-finally
1161 statement (bug #1509132).
1162
Neal Norwitz60373cd2006-06-22 06:30:50 +00001163- The wsgiref package is now installed properly on Unix.
1164
Vinay Sajip28e57612006-07-01 10:45:20 +00001165- A bug was fixed in logging.config.fileConfig() which caused a crash on
1166 shutdown when fileConfig() was called multiple times.
1167
Gerhard Häring762fbd32006-07-02 17:48:30 +00001168- The sqlite3 module did cut off data from the SQLite database at the first
1169 null character before sending it to a custom converter. This has been fixed
1170 now.

1173-----------------
1174
Tim Peters112aad32006-07-19 00:03:19 +00001175- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1176 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1177 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001178
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001179- Assigning None to pointer type fields in ctypes structures possible
1180 overwrote the wrong fields, this is fixed now.
1181
1182- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1183 on non-Windows platforms.
1184
1185- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1186 integer or long, without range checking.
1187
1188- Patch #1517790: It is now possible to use custom objects in the ctypes
1189 foreign function argtypes sequence as long as they provide a from_param
1190 method, no longer is it required that the object is a ctypes type.
1191
1192- The '_ctypes' extension module now works when Python is configured
1193 with the --without-threads option.
1194
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001195- Bug #1513646: os.access on Windows now correctly determines write
1196 access, again.
1197
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001198- Bug #1512695: cPickle.loads could crash if it was interrupted with
1199 a KeyboardInterrupt.
1200
Neal Norwitza12aa882006-07-06 06:45:08 +00001201- Bug #1296433: parsing XML with a non-default encoding and
1202 a CharacterDataHandler could crash the interpreter in pyexpat.
1203
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001204- Patch #1516912: improve Modules support for OpenVMS.

1208
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001209- Automate Windows build process for the Win64 SSL module.
1210
Tim Peters32a83612006-07-10 21:08:24 +00001211- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001212 Previously, the slight difference could cause compilation errors of the
1213 'zlib' module on systems with more than one version of zlib.
1214
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001215- The MSI compileall step was fixed to also support a TARGETDIR
1216 with spaces in it.
1217
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001218- Bug #1517388: sqlite3.dll is now installed on Windows independent
1219 of Tcl/Tk.
1220
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001221- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

1231-------------
1232
Nick Coghlan2d792252006-07-06 13:47:18 +00001233- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1234 documentation for the warnings module.
1235
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001236- Patch #1509163: MS Toolkit Compiler no longer available.
1237

Nick Coghlanc649ec52006-05-29 12:43:05 +00001241What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001242================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001243
Anthony Baxterd1136802006-06-19 12:04:15 +00001244*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001245
1246Core and builtins
1247-----------------
1248
Georg Brandla56b9152006-06-19 06:35:54 +00001249- Patch #1507676: Error messages returned by invalid abstract object operations
1250 (such as iterating over an integer) have been improved and now include the
1251 type of the offending object to help with debugging.
1252
Brett Cannonea3912b2006-06-13 21:46:41 +00001253- Bug #992017: A classic class that defined a __coerce__() method that returned
1254 its arguments swapped would infinitely recurse and segfault the interpreter.
1255
Neal Norwitz909eb122006-06-12 02:13:21 +00001256- Fix the socket tests so they can be run concurrently.
1257
Neal Norwitzb9845e72006-06-12 02:11:18 +00001258- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001259 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001260
Brett Cannon22565aa2006-06-09 22:31:23 +00001261- Bug #532646: object.__call__() will continue looking for the __call__
1262 attribute on objects until one without one is found. This leads to recursion
1263 when you take a class and set its __call__ attribute to an instance of the
1264 class. Originally fixed for classic classes, but this fix is for new-style.
1265 Removes the infinite_rec_3 crasher.
1266
Georg Brandl24250812006-06-09 18:45:48 +00001267- The string and unicode methods startswith() and endswith() now accept
1268 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1269
Brett Cannonde3b0522006-06-08 17:00:45 +00001270- Buffer objects, at the C level, never used the char buffer
1271 implementation even when the char buffer for the wrapped object was
1272 explicitly requested (originally returned the read or write buffer).
1273 Now a TypeError is raised if the char buffer is not present but is
1274 requested.
1275
Georg Brandlddbaa662006-06-04 21:56:52 +00001276- Patch #1346214: Statements like "if 0: suite" are now again optimized
1277 away like they were in Python 2.4.
1278
Georg Brandlb7c8f542006-05-27 12:30:25 +00001279- Builtin exceptions are now full-blown new-style classes instead of
1280 instances pretending to be classes, which speeds up exception handling
1281 by about 80% in comparison to 2.5a2.
1282
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001283- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1284 Unicode 4.1.
1285
Georg Brandlf4ef1162006-05-26 18:03:31 +00001286- Patch #921466: sys.path_importer_cache is now used to cache valid and
1287 invalid file paths for the built-in import machinery which leads to
1288 fewer open calls on startup.
1289
Tim Peters696cf432006-05-24 21:10:40 +00001290- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1291 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1292 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1293 the number of input digits (it was and remains linear-time for bases
1294 2, 4, 8, 16 and 32).
1295
Tim Petersb713ec22006-05-23 18:45:30 +00001296- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1297 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1298 an integer close to ``sys.maxint``. This was repaired by patch
1299 #1335972, which also gives a nice speedup.
1300
Richard Jonescebbefc2006-05-23 18:28:17 +00001301- Patch #1337051: reduced size of frame objects.
1302
1303- PyErr_NewException now accepts a tuple of base classes as its
1304 "base" parameter.
1305
Richard Jones7c88dcc2006-05-23 10:37:38 +00001306- Patch #876206: function call speedup by retaining allocated frame
1307 objects.
1308
Georg Brandl7b90e162006-05-18 07:01:27 +00001309- Bug #1462152: file() now checks more thoroughly for invalid mode
1310 strings and removes a possible "U" before passing the mode to the
1311 C library function.
1312
Neal Norwitz1004a532006-05-15 07:17:23 +00001313- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1314
Neal Norwitz373f0a72006-05-15 07:04:36 +00001315- Bug #1487966: Fix SystemError with conditional expression in assignment
1316
Martin v. Löwis879768d2006-05-11 13:28:43 +00001317- WindowsError now has two error code attributes: errno, which carries
1318 the error values from errno.h, and winerror, which carries the error
1319 values from winerror.h. Previous versions put the winerror.h values
1320 (from GetLastError()) into the errno attribute.
1321
Martin v. Löwis77736712006-05-04 05:51:03 +00001322- Patch #1475845: Raise IndentationError for unexpected indent.
1323
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001324- Patch #1479181: split open() and file() from being aliases for each other.
1325
Tim Peters44bd9862006-06-01 13:49:23 +00001326- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1327 methods were always silently ignored by dictionaries when comparing keys.
1328 They are now passed through (except when using the C API function
1329 ``PyDict_GetItem()``, whose semantics did not change).
1330
1331- Bug #1456209: In some obscure cases it was possible for a class with a
1332 custom ``__eq__()`` method to confuse dict internals when class instances
1333 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1334 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001336Extension Modules
1337-----------------
1338
Trent Mick960a3f82006-06-28 20:30:41 +00001339- Bug #1295808: expat symbols should be namespaced in pyexpat
1340
1341- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1342
Brett Cannon6ee7d012006-06-08 16:23:04 +00001343- Change binascii.hexlify to accept a read-only buffer instead of only a char
1344 buffer and actually follow its documentation.
1345
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001346- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1347
Nick Coghlanc649ec52006-05-29 12:43:05 +00001348- Patch #1478788 (modified version): The functional extension module has
1349 been renamed to _functools and a functools Python wrapper module added.
1350 This provides a home for additional function related utilities that are
1351 not specifically about functional programming. See PEP 309.
1352
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001353- Patch #1493701: performance enhancements for struct module.
1354
Georg Brandl378d5922006-05-17 14:26:50 +00001355- Patch #1490224: time.altzone is now set correctly on Cygwin.
1356
Georg Brandl8d3342b2006-05-16 07:38:27 +00001357- Patch #1435422: zlib's compress and decompress objects now have a
1358 copy() method.
1359
Andrew MacIntyre92913322006-06-13 15:04:24 +00001360- Patch #1454481: thread stack size is now tunable at runtime for thread
1361 enabled builds on Windows and systems with Posix threads support.
1362
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001363- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1364 (up to the system limit of 32K characters).
1365
1366- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1367 As a result, these functions now raise WindowsError instead of OSError.
1368
Tim Peters7a822da2006-05-25 21:50:17 +00001369- ``time.clock()`` on Win64 should use the high-performance Windows
1370 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1371 Windows platforms).
1372
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001373- Calling Tk_Init twice is refused if the first call failed as that
1374 may deadlock.
1375
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001376- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1377 accept it without potentially using an uninitialized pointer.
1378
1379- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1380 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1381 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001382
Gregory P. Smith372b5832006-06-05 18:48:21 +00001383- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001384 [pybsddb project SF patch number 1466734]
1385
Gregory P. Smith372b5832006-06-05 18:48:21 +00001386- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1387 parameter is supplied. [SF pybsddb bug #1477863]
1388
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001389- bsddb: the __len__ method of a DB object has been fixed to return correct
1390 results. It could previously incorrectly return 0 in some cases.
1391 Fixes SF bug 1493322 (pybsddb bug 1184012).
1392
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001393- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1394 aborts the db transaction safely when a modifier callback fails.
1395 Fixes SF python patch/bug #1408584.
1396
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001397- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001398 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001399 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1400 database calls that would previously deadlock. [SF python bug #775414]
1401
Vinay Sajip28e57612006-07-01 10:45:20 +00001402- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001403
Walter Dörwald4994d952006-06-19 08:07:50 +00001404- Patch #1506645: add Python wrappers for the curses functions
1405 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001406

1408-------
1409
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001410- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1411 functions.
1412
Martin v. Löwis3798da02006-06-17 18:44:27 +00001413- Patch #812986: Update turtle output even if not tracing.
1414
Vinay Sajip28e57612006-07-01 10:45:20 +00001415- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001416 Tkinter.BaseWidget.
1417
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001418- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1419
Martin v. Löwis337487e2006-06-17 09:15:14 +00001420- Patch #763580: Add name and value arguments to Tkinter variable
1421 classes.
1422
Georg Brandl83cc0d02006-06-14 08:50:03 +00001423- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1424 mime.types file for determining MIME types.
1425
Georg Brandl2605ca82006-06-14 06:08:31 +00001426- Bug #1339007: Shelf objects now don't raise an exception in their
1427 __del__ method when initialization failed.
1428
Martin v. Löwisd8251432006-06-14 05:21:04 +00001429- Patch #1455898: The MBCS codec now supports the incremental mode for
1430 double-byte encodings.
1431
Tim Peters43898b42006-06-14 04:09:25 +00001432- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1433 guarantee that adjacent triples in the return list always describe
1434 non-adjacent blocks. Previously, a pair of matching blocks could end
1435 up being described by multiple adjacent triples that formed a partition
1436 of the matching pair.
1437
Greg Ward0e0c9f42006-06-11 16:24:11 +00001438- Bug #1498146: fix optparse to handle Unicode strings in option help,
1439 description, and epilog.
1440
Greg Wardd1c797e2006-06-11 14:42:41 +00001441- Bug #1366250: minor optparse documentation error.
1442
Greg Ward7f547402006-06-11 00:40:49 +00001443- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1444 clarify docs.
1445
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001446- The wsgiref package has been added to the standard library.
1447
Nick Coghlan676725d2006-06-08 13:54:49 +00001448- The functions update_wrapper() and wraps() have been added to the functools
1449 module. These make it easier to copy relevant metadata from the original
1450 function when writing wrapper functions.
1451
Tim Petersd6a9eef2006-06-05 01:48:21 +00001452- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1453 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001454
Martin v. Löwis3f767792006-06-04 19:36:28 +00001455- Patch #1359618: Speed up charmap encoder by using a trie structure
1456 for lookup.
1457
Tim Petersd609b1a2006-06-02 23:22:51 +00001458- The functions in the ``pprint`` module now sort dictionaries by key
1459 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1460 if and only if its display required more than one line, although that
1461 wasn't documented. The new behavior increases predictability; e.g.,
1462 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1463
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001464- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1465 (thanks for J. J. Lee).
1466
Georg Brandl2b330372006-05-28 20:23:12 +00001467- Patch #1496206: improve urllib2 handling of passwords with respect to
1468 default HTTP and HTTPS ports.
1469
George Yoshidaf3c65de2006-05-28 16:39:09 +00001470- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1471
Bob Ippolito7298f272006-05-23 18:43:47 +00001472- Patch #1281707: speed up gzip.readline.
1473
Georg Brandlb89316f2006-05-17 15:51:16 +00001474- Patch #1180296: Two new functions were added to the locale module:
1475 format_string() to get the effect of "format % items" but locale-aware,

Georg Brandle3a25832006-05-17 14:56:04 +00001478- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1479 and several features added, such as speed and geometry control.
1480
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001481- Patch #1488881: add support for external file objects in bz2 compressed
1482 tarfiles.
1483
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001484- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1485 stdout arguments, making it possible to redirect input and output
1486 for remote debugging.
1487
1488- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1489 a couple of issues, notably handling of long file names using the
1490 GNU LONGNAME extension.
1491
1492- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1493 new flag when ``name`` is already the name of an option flag.
1494
1495- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1496 package.
1497
1498- Patch #1472854: make the rlcompleter.Completer class usable on non-
1499 UNIX platforms.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001534What's New in Python 2.5 alpha 2?
1535=================================
1536
1537*Release date: 27-APR-2006*
1538
1539Core and builtins
1540-----------------
1541
Thomas Heller1b046642006-04-18 18:51:06 +00001542- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1543 by converting these apis from macros into exported functions again:
1544
1545 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1546 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1547 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1548 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1549 PyRun_String Py_CompileString
1550
Martin v. Löwis45294a92006-04-18 06:24:08 +00001551- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1552
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001553- All uses of PyStructSequence_InitType have been changed to initialize
1554 the type objects only once, even if the interpreter is initialized
1555 multiple times.
1556
Neal Norwitz61546162006-04-14 05:20:28 +00001557- Bug #1454485, array.array('u') could crash the interpreter. This was
1558 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1559 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1560
1561- Py_UNICODE is unsigned. It was always documented as unsigned, but
1562 due to a bug had a signed value in previous versions.
1563
Tim Peters3a5e8b12006-04-11 01:44:07 +00001564- Patch #837242: ``id()`` of any Python object always gives a positive
1565 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1566 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001567 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001568 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001569
Tim Peters3a5e8b12006-04-11 01:44:07 +00001570 def __hash__(self):
1571 return id(self) # WRONG
1572
1573 because a hash result must be a (short) Python int but it was always
1574 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001575 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001576 was always usable as a hash value before this patch. That's no longer
1577 necessarily so.
1578
1579- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001580 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001581 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001582 #1454844)
1583
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001584- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1585 involving generators that have paused outside of any ``try`` or ``with``
1586 blocks. (In 2.5a1, a paused generator that was part of a reference
1587 cycle could not be garbage collected, regardless of whether it was
1588 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001589
Anthony Baxter51bcb682006-04-05 14:51:42 +00001590Extension Modules

1592
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001593- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1594 is a macro.
1595
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001596- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1597 fails with an error condition.
1598
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001599- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1600
1601- Bug #1117761: bsddb.*open() no longer raises an exception when using
1602 the cachesize parameter.
1603
1604- Bug #1149413: bsddb.*open() no longer raises an exception when using
1605 a temporary db (file=None) with the 'n' flag to truncate on open.
1606
1607- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1608 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001609
Armin Rigoa9017c32006-04-19 11:50:27 +00001610- Patch #1062014: AF_UNIX sockets under Linux have a special
1611 abstract namespace that is now fully supported.
1612

1614-------
1615
Peter Astrand7d1d4362006-07-14 14:04:45 +00001616- Bug #1223937: subprocess.CalledProcessError reports the exit status
1617 of the process using the returncode attribute, instead of
1618 abusing errno.
1619
Tim Peters711bf302006-04-25 03:31:36 +00001620- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1621 a doctest to be skipped (the code is not run, and the expected output
1622 or exception is ignored).
1623
Nick Coghlanda2268f2006-04-24 04:37:15 +00001624- Fixed contextlib.nested to cope with exceptions being raised and
1625 caught inside exit handlers.
1626
Greg Wardab05edc2006-04-23 03:47:58 +00001627- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1628 hex, octal, or binary; add ``append_const`` action; keep going if
1629 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1630 added ``epilog`` for better help generation).
1631
Tim Peters21fbd572006-04-21 21:18:10 +00001632- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1633 called from a thread spawned as a side effect of importing a module.
1634
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001635- The pydoc module now supports documenting packages contained in
1636 .zip or .egg files.
1637
1638- The pkgutil module now has several new utility functions, such
1639 as ``walk_packages()`` to support working with packages that are either
1640 in the filesystem or zip files.
1641
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001642- The mailbox module can now modify and delete messages from
1643 mailboxes, in addition to simply reading them. Thanks to Gregory
1644 K. Johnson for writing the code, and to the 2005 Google Summer of
1645 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001646
Tim Petersc7605f22006-04-17 21:12:33 +00001647- The ``__del__`` method of class ``local`` in module ``_threading_local``
1648 returned before accomplishing any of its intended cleanup.
1649
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001650- Patch #790710: Add breakpoint command lists in pdb.
1651
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001652- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1653
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001654- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1655
Anthony Baxtere29002c2006-04-12 12:07:31 +00001656- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1657 Windows. Bug #1469163.
1658
Phillip J. Eby47032112006-04-11 01:07:43 +00001659- The warnings, linecache, inspect, traceback, site, and doctest modules
1660 were updated to work correctly with modules imported from zipfiles or
1661 via other PEP 302 __loader__ objects.
1662
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001663- Patch #1467770: Reduce usage of subprocess._active to processes which
1664 the application hasn't waited on.
1665
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001666- Patch #1462222: Fix Tix.Grid.
1667
Neal Norwitza31bf182006-04-09 03:35:43 +00001668- Fix exception when doing glob.glob('anything*/')
1669
Skip Montanaro262fb922006-04-21 02:31:07 +00001670- The pstats.Stats class accepts an optional stream keyword argument to
1671 direct output to an alternate file-like object.
1672
Anthony Baxter51bcb682006-04-05 14:51:42 +00001673Build
1674-----
1675
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001676- The Makefile now has a reindent target, which runs reindent.py on
1677 the library.
1678
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001679- Patch #1470875: Building Python with MS Free Compiler
1680
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001681- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001682
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001683- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1684 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001685 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001686 CXX from --with-cxx-main, see description in README.
1687
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001688- Patch #1429775: Link extension modules with the shared libpython.
1689
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001690- Fixed a libffi build problem on MIPS systems.
1691
Tim Peters8931ff12006-05-13 23:28:20 +00001692- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1693 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1694 and "%zu" for unsigned integers of type ``size_t``.
1695
Anthony Baxter51bcb682006-04-05 14:51:42 +00001696Tests
1697-----
1698
Nick Coghlanda2268f2006-04-24 04:37:15 +00001699- test_contextlib now checks contextlib.nested can cope with exceptions
1700 being raised and caught inside exit handlers.
1701
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001702- test_cmd_line now checks operation of the -m and -c command switches
1703
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001704- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1705 it separately and by hand. It also wasn't cleaning up its changes to
1706 the current Decimal context.
1707
Thomas Woutersabd08882006-04-26 15:53:30 +00001708- regrtest.py now has a -M option to run tests that test the new limits of
1709 containers, on 64-bit architectures. Running these tests is only sensible
1710 on 64-bit machines with more than two gigabytes of memory. The argument
1711 passed is the maximum amount of memory for the tests to use.
1712
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001713Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001719Documentation
1720-------------
1721
Tim Petersb06d28c2006-05-12 01:57:59 +00001722- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1723
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001724- PEP 343: Added Context Types section to the library reference
1725 and attempted to bring other PEP 343 related documentation into
1726 line with the implementation and/or python-dev discussions.
1727
Tim Peters8dc73d22006-04-24 02:03:16 +00001728- Bug #1337990: clarified that ``doctest`` does not support examples
1729 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001732What's New in Python 2.5 alpha 1?
1733=================================
1734
Anthony Baxterebed3f62006-04-03 15:03:44 +00001735*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001736
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001737Core and builtins
1738-----------------
1739
Nick Coghlan43832302006-04-23 17:04:07 +00001740- PEP 338: -m command line switch now delegates to runpy.run_module
1741 allowing it to support modules in packages and zipfiles
1742
Martin v. Löwisc661b882006-04-20 04:54:23 +00001743- On Windows, .DLL is not an accepted file name extension for
1744 extension modules anymore; extensions are only found if they
1745 end in .PYD.
1746
Martin v. Löwisea62d252006-04-03 10:56:49 +00001747- Bug #1421664: sys.stderr.encoding is now set to the same value as
1748 sys.stdout.encoding.
1749
Neal Norwitz92e212f2006-04-03 04:48:37 +00001750- __import__ accepts keyword arguments.
1751
Georg Brandlccadf842006-03-31 18:54:53 +00001752- Patch #1460496: round() now accepts keyword arguments.
1753
Anthony Baxter262c00a2006-03-30 10:53:17 +00001754- Fixed bug #1459029 - unicode reprs were double-escaped.
1755
Hye-Shik Changd478f342006-03-23 12:32:36 +00001756- Patch #1396919: The system scope threads are reenabled on FreeBSD
1757 5.4 and later versions.
1758
Neal Norwitze98ccf62006-03-23 05:39:47 +00001759- Bug #1115379: Compiling a Unicode string with an encoding declaration
1760 now gives a SyntaxError.
1761
Georg Brandlabd1ff82006-03-18 07:59:59 +00001762- Previously, Python code had no easy way to access the contents of a
1763 cell object. Now, a ``cell_contents`` attribute has been added
1764 (closes patch #1170323).
1765
Tim Peterscf79aac2006-03-16 01:14:46 +00001766- Patch #1123430: Python's small-object allocator now returns an arena to
1767 the system ``free()`` when all memory within an arena becomes unused
1768 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1769 freed. Some applications will see a drop in virtual memory size now,
1770 especially long-running applications that, from time to time, temporarily
1771 use a large number of small objects. Note that when Python returns an
1772 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001773 platform C library will in turn return that memory to the operating system.
1774 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001775 appears to be effective at least on Microsoft C and gcc-based systems.
1776 Thanks to Evan Jones for hard work and patience.
1777
Georg Brandl533ff6f2006-03-08 18:09:27 +00001778- Patch #1434038: property() now uses the getter's docstring if there is
1779 no "doc" argument given. This makes it possible to legitimately use
1780 property() as a decorator to produce a read-only property.
1781
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001782- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1783 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1784 of requiring an int or long in slicing and a few other contexts, enabling
1785 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1786
Neal Norwitz995acdf2006-03-07 05:01:00 +00001787- Fixed various bugs reported by Coverity's Prevent tool.
1788
Brett Cannonbf364092006-03-01 04:25:17 +00001789- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1790 new exception base class, BaseException, which has a new message attribute.
1791 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1792 Raising a string exception now raises a DeprecationWarning.
1793
Thomas Woutersfb609f42006-02-28 16:37:25 +00001794- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1795 explicitly relative, using 'from .module import name' to mean 'from the same
1796 package as this module is in. Imports without dots still default to the
1797 old relative-then-absolute, unless 'from __future__ import
1798 absolute_import' is used.
1799
Brett Cannona7446e32006-02-27 23:39:10 +00001800- Properly check if 'warnings' raises an exception (usually when a filter set
1801 to "error" is triggered) when raising a warning for raising string
1802 exceptions.
1803
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001804- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001805 The name was removed from Include/code.h.
1806
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001807- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001808
Guido van Rossum1968ad32006-02-25 22:38:04 +00001809- Patch 1433928:
1810 - The copy module now "copies" function objects (as atomic objects).
1811 - dict.__getitem__ now looks for a __missing__ hook before raising
1812 KeyError.
1813
Tim Peters84ef21c2006-02-28 20:39:06 +00001814- PEP 343: with statement implemented. Needs ``from __future__ import
1815 with_statement``. Use of 'with' as a variable will generate a warning.
1816 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001817 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001818 The following objects have __context__ methods:
1819 - The built-in file type.
1820 - The thread.LockType type.
1821 - The following types defined by the threading module:
1822 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1823 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001824
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001825- Fix the encodings package codec search function to only search
1826 inside its own package. Fixes problem reported in patch #1433198.
1827
1828 Note: Codec packages should implement and register their own
1829 codec search function. PEP 100 has the details.
1830
Tim Peters9ea89d22006-06-04 03:26:02 +00001831- PEP 353: Using ``Py_ssize_t`` as the index type.
1832
1833- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1834 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1835 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1836 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1837 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001838
Neal Norwitzfc76d632006-01-10 06:03:13 +00001839- Patch #1400181, fix unicode string formatting to not use the locale.
1840 This is how string objects work. u'%f' could use , instead of .
1841 for the decimal point. Now both strings and unicode always use periods.
1842
Neal Norwitz671b9e32006-01-09 07:07:12 +00001843- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1844 configure would break checking curses.h.
1845
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001846- Bug #959576: The pwd module is now builtin. This allows Python to be
1847 built on UNIX platforms without $HOME set.
1848
Neal Norwitzc10978f2005-12-19 06:07:16 +00001849- Bug #1072182, fix some potential problems if characters are signed.
1850
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001851- Bug #889500, fix line number on SyntaxWarning for global declarations.
1852
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001853- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1854
Neal Norwitze7214a12005-12-18 05:03:17 +00001855- Support for converting hex strings to floats no longer works.
1856 This was not portable. float('0x3') now raises a ValueError.
1857
Barry Warsaw2a38a862005-12-18 01:27:35 +00001858- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001859 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001860 is now displayed in interactive prompt banner.
1861
Georg Brandlfa166682005-12-17 21:45:17 +00001862- Implementation of PEP 341 - Unification of try/except and try/finally.
1863 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001864 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001865
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001866- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1867 now encodes backslash correctly.
1868
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001869- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1870
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001871- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001872 and long longs.
1873
Neal Norwitz67715f02005-11-09 06:59:35 +00001874- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001875 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001876 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001877
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001878- Replaced most Unicode charmap codecs with new ones using the
1879 new Unicode translate string feature in the builtin charmap
1880 codec; the codecs were created from the mapping tables available
1881 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1882 encodings now include a mapping for the Apple logo)
1883
Tim Peterse3547fd2005-12-16 23:13:57 +00001884- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001885
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001886- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001887
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001888- A new AST parser implementation was completed. The abstract
1889 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001890 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001891
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001892- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001893 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1894
Neal Norwitz708e51a2005-10-03 04:48:15 +00001895- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1896
Neal Norwitz11bd1192005-10-03 00:54:56 +00001897- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1898 Provide a warning when a directory is passed on the command line.
1899
Neal Norwitz40d37812005-10-02 01:48:49 +00001900- Fix segfault with invalid coding.
1901
1902- SF bug #772896: unknown encoding results in MemoryError.
1903
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001904- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001905 supported a __len__() method which evaluated to False when the iterator
1906 was empty.
1907
Guido van Rossum630db602005-09-20 18:49:54 +00001908- On 64-bit platforms, when __len__() returns a value that cannot be
1909 represented as a C int, raise OverflowError.
1910
Skip Montanarof8948ca2005-09-19 03:54:46 +00001911- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001912 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001913
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001914- SF bug #893549: parsing keyword arguments was broken with a few format
1915 codes.
1916
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001917- Changes donated by Elemental Security to make it work on AIX 5.3
1918 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1919 bug #105470: test_pwd fails on 64bit system (Opteron).
1920
Guido van Rossum539c6622005-09-14 17:49:54 +00001921- Changes donated by Elemental Security to make it work on HP-UX 11 on
1922 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1923
Georg Brandl4550b8d2005-08-26 06:43:52 +00001924- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001925 (fixes bug #1119418).
1926
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001927- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1928
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001929- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1930 exceptions that cause a function to exit.
1931
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001932- The implementation of set() and frozenset() was revised to use its
1933 own internal data structure. Memory consumption is reduced by 1/3
1934 and there are modest speed-ups as well. The API is unchanged.
1935
Tim Petersde7990b2005-07-17 23:45:23 +00001936- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1937
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001938- SF bug #1229429: PyObject_CallMethod failed to decrement some
1939 reference counts in some error exit cases.
1940
Tim Petersecc6e6a2005-07-10 22:30:55 +00001941- SF bug #1185883: Python's small-object memory allocator took over
1942 a block managed by the platform C library whenever a realloc specified
1943 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001944 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001945 portable way to copy data from the C-managed block into Python's
1946 small-object space without risking a memory fault. Python's small-object
1947 realloc now leaves such blocks under the control of the platform C
1948 realloc.
1949
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001950- SF bug #1232517: An overflow error was not detected properly when
1951 attempting to convert a large float to an int in os.utime().
1952
Raymond Hettinger3296e692005-06-29 23:29:56 +00001953- SF bug #1224347: hex longs now print with lowercase letters just
1954 like their int counterparts.
1955
Michael W. Hudson188d4362005-06-20 16:52:57 +00001956- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1957 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1958 interpreter states; back out that fix and do a better job (see
1959 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1960 for a longer write-up of the problem).
1961
Michael W. Hudsondf888462005-06-03 14:41:55 +00001962- SF patch #1180995: marshal now uses a binary format by default when
1963 serializing floats.
1964
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001965- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1966 the routines that promise to produce IEEE 754 binary representations
1967 of floats now simply copy bytes around.
1968
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001969- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1970 278.
1971
Brett Cannonc3647ac2005-04-26 03:45:26 +00001972- patch #1109424: int, long, float, complex, and unicode now check for the
1973 proper magic slot for type conversions when subclassed. Previously the
1974 magic slot was ignored during conversion. Semantics now match the way
1975 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001976 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001977 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001978 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001979
Barry Warsawc8d907c2005-04-19 23:43:40 +00001980- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1981 NULL, now raise an AttributeError when attempting to set or delete the
1982 attribute. Previously a TypeError was raised, but this was inconsistent
1983 with the equivalent pure-Python implementation.
1984
Michael W. Hudson774479c2005-04-18 08:46:17 +00001985- It is now safe to call PyGILState_Release() before
1986 PyEval_InitThreads() (note that if there is reason to believe there
1987 are multiple threads around you still must call PyEval_InitThreads()
1988 before using the Python API; this fix is for extension modules that
1989 have no way of knowing if Python is multi-threaded yet).
1990
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001991- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1992 disabled caused a crash.
1993
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001994- Bug #1165306: instancemethod_new allowed the creation of a method
1995 with im_class == im_self == NULL, which caused a crash when called.
1996
Tim Petersecc6e6a2005-07-10 22:30:55 +00001997- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001998 fixes the crash seen in bug #1165761
1999
Raymond Hettinger96229b12005-03-11 06:49:40 +00002000- Added two new builtins, any() and all().
2001
Brett Cannon409d8f22005-03-05 06:47:57 +00002002- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002003 (e.g., ``class C(): pass`` is no longer a syntax error).
2004 Patch #1176012 added support to the 'parser' module and 'compiler' package
2005 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002006
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002007- Patch #1115086: Support PY_LONGLONG in structmember.
2008
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002009- Bug #1155938: new style classes did not check that __init__() was
2010 returning None.
2011
Tim Petersecc6e6a2005-07-10 22:30:55 +00002012- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002013 ('\') with a specific error message.
2014
Martin v. Löwisff232d72005-03-03 09:24:38 +00002015- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2016
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002017- Bug #1124295: the __name__ attribute of file objects was
2018 inadvertently made inaccessible in restricted mode.
2019
Tim Petersecc6e6a2005-07-10 22:30:55 +00002020- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002021 an ferror() call.
2022
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002023- min() and max() now support key= arguments with the same meaning as in
2024 list.sort().
2025
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002026- The peephole optimizer now performs simple constant folding in expressions:
2027 (2+3) --> (5).
2028
Raymond Hettingera422c342005-01-11 03:03:27 +00002029- set and frozenset objects can now be marshalled. SF #1098985.
2030
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002031- Bug #1077106: Poor argument checking could cause memory corruption
2032 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002033
Jeremy Hyltonab630502005-02-04 18:44:06 +00002034- The parser did not complain about future statements in illegal
2035 positions. It once again reports a syntax error if a future
2036 statement occurs after anything other than a doc string.
2037
Neil Schemenauercf52c072005-08-12 17:34:58 +00002038- Change the %s format specifier for str objects so that it returns a
2039 unicode instance if the argument is not an instance of basestring and
2040 calling __str__ on the argument returns a unicode instance.
2041
Tim Petersf4e69282006-02-27 17:15:31 +00002042- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2043 current thread state when the auto-GIL-state machinery knows about
2044 it (since the thread state is being deleted, continuing to remember it
2045 can't help, but can hurt if another thread happens to get created with
2046 the same thread id).

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002241
Nick Coghlan43832302006-04-23 17:04:07 +00002242- PEP 338: new module runpy defines a run_module function to support
2243 executing modules which provide access to source code or a code object
2244 via the PEP 302 import mechanisms.
2245
Anthony Baxter93f5b932006-04-03 08:05:07 +00002246- The email module's parsedate_tz function now sets the daylight savings

2254 in attribute values.
2255
Anthony Baxterc51ee692006-04-01 00:57:31 +00002256- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002257 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002258 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002259 module will not be built.
2260
Tim Petersc17976e2006-04-01 00:26:53 +00002261- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2262 aren't officially supported here, and trying to use them will probably
2263 raise an exception some day. But dicts have been allowed, and "mostly
2264 worked", so support for them won't go away without warning.
2265
Georg Brandl338ef7d2006-03-31 18:42:16 +00002266- Bug #1445068: getpass.getpass() can now be given an explicit stream
2267 argument to specify where to write the prompt.
2268
Georg Brandl22ec80b2006-03-31 18:25:44 +00002269- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2284
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002285- email 4.0 package now integrated. This is largely the same as the email 3.0
2286 package that was included in Python 2.3, except that PEP 8 module names are
2287 now used (e.g. mail.message instead of email.Message). The MIME classes
2288 have been moved to a subpackage (e.g. email.mime.text instead of
2289 email.MIMEText). The old names are still supported for now. Several
2290 deprecated Message methods have been removed and lots of bugs have been
2291 fixed. More details can be found in the email package documentation.
2292
Walter Dörwald40108c92006-03-27 08:15:44 +00002293- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2294 (a subclass of tuple) that provides incremental decoders and encoders
2295 (a way to use stateful codecs without the stream API). Python functions
2296 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2297 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2298 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002300- Patch #1359365: Calling next() on a closed StringIO.String object raises
2301 a ValueError instead of a StopIteration now (like file and cString.String do).
2302 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2303 called before (like file and StringIO.StringIO do).

Martin v. Löwis04824ce2006-03-10 21:26:16 +00002305- A regrtest option -w was added to re-run failed tests in verbose mode.

2311 grew an optional 'generation' argument.
2312
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002313- A library msilib to generate Windows Installer files, and a distutils

2383 expressed at the NIST Hash Function Workshop 10/31/05),
2384 is that SHA-256 is a good choice for the time being, but
2385 that research should continue, and other alternatives may
2386 arise from this research. The larger SHA's also seem OK."

Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002571 + Dialect parameter parsing has been re-implemented to improve error
2572 reporting.
2573 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2574 dictates.
2575 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002576 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002577 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002578 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2579 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002580 + reader now allows \r characters to be quoted (previously it only allowed
2581 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002582 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002583 + Dialect classes passed to the module are no longer instantiated by
2584 the module before being parsed (the former validation scheme required
2585 this, but the mechanism was unreliable).
2586 + The dialect registry now contains instances of the internal
2587 C-coded dialect type, rather than references to python objects.
2588 + the internal c-coded dialect type is now immutable.
2589 + register_dialect now accepts the same keyword dialect specifications
2590 as the reader and writer, allowing the user to register dialects
2591 without first creating a dialect class.
2592 + a configurable limit to the size of parsed fields has been added -
2593 previously, an unmatched quote character could result in the entire
2594 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002595 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002596 the parser field size limit (returning the former limit). The initial
2597 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002598 + A line_num attribute has been added to the reader object, which tracks
2599 the number of lines read from the source iterator. This is not
2600 the same as the number of records returned, as records can span
2601 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002602 + reader and writer objects were not being registered with the cyclic-GC.
2603 This has been fixed.
2604
Brett Cannone6539c42005-01-08 02:43:53 +00002605- _DummyThread objects in the threading module now delete self.__block that is
2606 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2607 lock primitives tend to be limited in number and thus should not be wasted on
2608 a _DummyThread object. Fixes bug #1089632.
2609
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002610- The imghdr module now detects Exif files.
2611
Raymond Hettinger6065d322004-12-20 23:51:53 +00002612- StringIO.truncate() now correctly adjusts the size attribute.
2613 (Bug #951915).
2614
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002615- locale.py now uses an updated locale alias table (built using
2616 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2617 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002618 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002619
Raymond Hettinger3557f422004-12-07 12:02:02 +00002620- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2621
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002622- the pickle module no longer accepts the deprecated None option in the
2623 args tuple returned by __reduce__().
2624
Brett Cannon84667c02004-12-07 03:25:18 +00002625- optparse now optionally imports gettext. This allows its use in setup.py.
2626
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002627- the pickle module no longer uses the deprecated bin parameter.
2628
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002629- the shelve module no longer uses the deprecated binary parameter.
2630
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002631- the pstats module no longer uses the deprecated ignore() method.
2632
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002633- the filecmp module no longer uses the deprecated use_statcache argument.
2634
Raymond Hettinger664347b2004-12-04 21:21:53 +00002635- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2636 extended or overridden by subclasses. Formerly, the subclassed method would
2637 be ignored by the rest of the module. (Bug #1078905).
2638
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002639- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002640 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002641
Walter Dörwald36733692004-12-22 12:50:50 +00002642- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2643 once when a size argument is given. This prevents a buffer overflow in the
2644 tokenizer with very long source lines.
2645
Barry Warsaw538561e2006-01-01 21:48:54 +00002646- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2647 immediately after creating the object, without any intervening
2648 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002649
Skip Montanaro05885812005-01-16 20:48:27 +00002650- The reconvert.quote function can now emit triple-quoted strings. The
2651 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002652
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002653- ``UserString.MutableString`` now supports negative indices in
2654 ``__setitem__`` and ``__delitem__``
2655
Greg Ward40407942005-03-05 02:53:17 +00002656- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2657 correctly.
2658
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002659- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2660 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2661 character even if the user has passed a size parameter to get a proper
2662 line ending. Remove the special handling of a "\r\n" that has been split
2663 between two lines.
2664
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002665- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2666 about illegal code points. The codec now supports PEP 293 style error
2667 handlers.
2668
Walter Dörwald78a78b02005-09-01 12:04:29 +00002669- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002670 from the input stream, so that the output is a byte string in the correct
2671 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002672
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002673- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2674 considering it exactly like a '*'.
2675
Walter Dörwald007f8df2005-10-09 19:42:27 +00002676- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2677 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002678
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002679- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2680
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002681- Patch #1413711: Certain patterns of differences were making difflib
2682 touch the recursion limit.
2683
Walter Dörwald58917a62006-03-31 15:26:22 +00002684- Bug #947906: An object oriented interface has been added to the calendar
2685 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002686 called as a script (e.g. via ``python -mcalendar``). Localized month and
2687 weekday names can be ouput (even if an exotic encoding is used) using
2688 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002689
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002690Build
2691-----
2692
Neal Norwitz602d3392006-03-31 08:21:40 +00002693- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2694 by using -mieee gcc option.
2695
Martin v. Löwis86d66262006-02-17 08:40:11 +00002696- Patch #1432345: Make python compile on DragonFly.
2697
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002698- Build support for Win64-AMD64 was added.
2699
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002700- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2701
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002702- Patch #881820: look for openpty and forkpty also in libbsd.
2703
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002704- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2705 The zlib module is now builtin on Windows.
2706
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002707- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2708
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002709- Bug #1189330: configure did not correctly determine the necessary
2710 value of LINKCC if python was built with GCC 4.0.
2711
Trent Mick8321b422005-07-26 02:29:21 +00002712- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2713 vulnerability in zlib 1.2.1 and 1.2.2.
2714
Brett Cannon08cd5982005-04-24 22:26:38 +00002715- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2716 flags that change binary compatibility. Changes were also made to
2717 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002718 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002719
Bob Ippolitoed233462005-03-29 13:47:59 +00002720- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2721 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2722 no longer exists). This configure patch makes things right.
2723
Martin v. Löwise2713be2005-03-08 15:03:08 +00002724- Bug #1158607: Build with --disable-unicode again.
2725
Brett Cannon46d96232005-02-16 00:07:19 +00002726- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2727 defined. Discovered as a result of not being able to build on OS X.
2728
Brett Cannon516592f2004-12-07 00:42:59 +00002729- setup.py now uses the directories specified in LDFLAGS using the -L option
2730 and in CPPFLAGS using the -I option for adding library and include
2731 directories, respectively, for compiling extension modules against. This has
2732 led to the core being compiled using the values in CPPFLAGS. It also removes
2733 the need for the special-casing of both DarwinPorts and Fink for darwin since
2734 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2735 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2736 Fink, ``-I/opt/local/include`` for DarwinPorts).
2737
Brett Cannon43802422005-02-10 20:48:03 +00002738- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2739 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2740 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2741 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002743C API
2744-----
2745
Tim Petersc9d78aa2006-03-26 23:27:58 +00002746- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2747 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2748 is obtained via the ``PyObject_`` family, it must be released via the
2749 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2750 always been officially true, but when Python's small-object allocator was
2751 introduced, an attempt was made to cater to a few extension modules
2752 discovered at the time that obtained memory via ``PyObject_New`` but
2753 released it via ``PyMem_DEL``. It's years later, and if such code still
2754 exists it will fail now (probably with segfaults, but calling wrong
2755 low-level memory management functions can yield many symptoms).
2756
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002757- Added a C API for set and frozenset objects.
2758
Raymond Hettinger66517482004-12-03 11:45:13 +00002759- Removed PyRange_New().
2760
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002761- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2762 mapping argument now. This string is used as a mapping table. Byte values
2763 greater than the length of the string and 0xFFFE are treated as undefined
2764 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002771
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002772- Patch #1276356: New resource "urlfetch" is implemented. This enables
