12Core and builtins
13-----------------
14
Žiga Seilnacht71436f02007-03-14 12:24:09 +000015- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
16 name.
17
Georg Brandl5240d742007-03-13 20:46:32 +000018- Patch #1444529: the builtin compile() now accepts keyword arguments.
19
Georg Brandl7b9c5552007-03-12 14:30:05 +000020- Bug #1678647: write a newline after printing an exception in any
21 case, even when converting the value to a string failed.
22
Georg Brandl871f1bc2007-03-12 13:17:36 +000023- The dir() function has been extended to call the __dir__() method on
24 its argument, if it exists. If not, it will work like before. This allows
25 customizing the output of dir() in the presence of a __getattr__().
26
Collin Winter276887b2007-03-12 16:11:39 +000027- Patch #922167: Python no longer segfaults when faced with infinitely
28 self-recursive reload() calls (as reported by bug #742342).
29
Žiga Seilnacht89032082007-03-11 15:54:54 +000030- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
31
Collin Wintere38051d2007-03-09 20:33:07 +000032- Patch #1491866: change the complex() constructor to allow parthensized
33 forms. This means complex(repr(x)) now works instead of raising a
34 ValueError.
35
Georg Brandlaa2321b2007-03-07 00:40:28 +000036- Patch #703779: unset __file__ in __main__ after running a file. This
37 makes the filenames the warning module prints much more sensible when
38 a PYTHONSTARTUP file is used.
39
Georg Brandl49aafc92007-03-07 00:34:46 +000040- Variant of patch #697613: don't exit the interpreter on a SystemExit
41 exception if the -i command line option or PYTHONINSPECT environment
42 variable is given, but break into the interactive interpreter just like
43 on other exceptions or normal program exit.
44
Georg Brandl00cd8182007-03-06 18:41:12 +000045- Patch #1638879: don't accept strings with embedded NUL bytes in long().
46
Georg Brandl098cd692007-03-06 12:17:50 +000047- Bug #1674503: close the file opened by execfile() in an error condition.
48
Georg Brandl0fca97a2007-03-05 22:28:08 +000049- Patch #1674228: when assigning a slice (old-style), check for the
50 sq_ass_slice instead of the sq_slice slot.
51
Neal Norwitz88516a62007-02-26 22:41:45 +000052- When printing an unraisable error, don't print exceptions. before the name.
53 This duplicates the behavior whening normally printing exceptions.
54
Martin v. Löwisfd963262007-02-09 12:19:32 +000055- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
56
Brett Cannon129bd522007-01-30 21:34:36 +000057- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
58 catch a string exception raises DeprecationWarning.
59
Brett Cannonf5bee302007-01-23 23:21:22 +000060- Bug #1377858: Fix the segfaulting of the interpreter when an object created
61 a weakref on itself during a __del__ call for new-style classes (classic
62 classes still have the bug).
63
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000064- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
65 frame's thread state.

72 raised a warning.
73
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +000074- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
75 to avoid relying on atexit.
76
Raymond Hettinger94547f72006-12-20 06:42:06 +000077- Bug #1590891: random.randrange don't return correct value for big number

92
Thomas Hellerdf08f0b2006-10-27 18:31:36 +000093- Bug #1576174: WindowsError now displays the windows error code

95
Martin v. Löwisb5bc5372006-10-27 06:16:31 +000096- Patch #1549049: Support long values in structmember, issue warnings
97 if the assigned value for structmember fields gets truncated.
98
Neal Norwitzcbeb6872006-10-14 21:33:38 +000099- Update the peephole optimizer to remove more dead code (jumps after returns)
100 and inline unconditional jumps to returns.

104
Georg Brandl846f73a2006-10-08 07:11:54 +0000105- Bug #1569998: break inside a try statement (outside a loop) is now

109
110- Fix some leftovers from the conversion from int to Py_ssize_t
111 (relevant to strings and sequences of more than 2**31 items).
112
113- A number of places, including integer negation and absolute value,
114 were fixed to not rely on undefined behaviour of the C compiler
115 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000116
Georg Brandl3267d282006-09-30 09:03:42 +0000117- Bug #1566800: make sure that EnvironmentError can be called with any

133
Brett Cannon9adeab72006-09-20 18:34:28 +0000134- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
135 allows calling unicode() on exceptions classes directly to succeed.
136
Georg Brandlec6c2df2006-09-11 09:38:35 +0000137- Make _PyGILState_NoteThreadState() static, it was not used anywhere

145 imports (if not in package and if beyond toplevel package).
146
Tim Petersc10c9d02006-09-05 02:18:09 +0000147- Overflow checking code in integer division ran afoul of new gcc
148 optimizations. Changed to be more standard-conforming.
149

156
Neal Norwitzdac090d2006-09-05 03:53:08 +0000157- Bug #1520864: unpacking singleton tuples in list comprehensions and
158 generator expressions (x for x, in ... ) works again. Fixing this problem
159 required changing the .pyc magic number. This means that .pyc files

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000166- Add new requirements for metaclasses. 1) If type or a subclass of type
167 occurs in __bases__, it must occur before any non-type bases, e.g.
168 before regular classes. 2) If you assign to __bases__, you may not
169 change the metaclass. Many more illegal assignments to __bases__
170 are now checked and raise TypeErrors. This changed fixed at least
171 one known crash.

258 and TestSuite subclasses (not instances) are no longer accepted in

585 arguments with the system default encoding just like the write()
586 method does, instead of converting it to a raw buffer.
587

Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000614- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
615 mode by only placing a timeout on the select() if an input hook has
616 been defined. This prevents an interactive Python from waking up 10
617 times per second. Patch by Richard Boulton.

749=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000750
Anthony Baxterb4096662006-08-16 03:42:26 +0000751*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000752
753Core and builtins
754-----------------
755
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000756- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000757 compared equal or unequal to a string and a UnicodeDecodeError
758 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000759
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000760 Instead, the equal (==) and unequal (!=) comparison operators will
761 now issue a UnicodeWarning and interpret the two objects as
762 unequal. The UnicodeWarning can be filtered as desired using
763 the warning framework, e.g. silenced completely, turned into an
764 exception, logged, etc.
765
766 Note that compare operators other than equal and unequal will still
767 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000768
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000769- Fix segfault when doing string formatting on subclasses of long.
770
771- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
772 with new-style classes.
773
774- Fix bug related to __len__ functions returning negative values with
775 classic classes.
776
777- Patch #1538606, Fix __index__() clipping. There were some problems
778 discovered with the API and how integers that didn't fit into Py_ssize_t
779 were handled. This patch attempts to provide enough alternatives
780 to effectively use __index__.
781
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000782- Bug #1536021: __hash__ may now return long int; the final hash
783 value is obtained by invoking hash on the long int.
784
Thomas Hellerab1049c2006-08-08 17:37:00 +0000785- Bug #1536786: buffer comparison could emit a RuntimeWarning.
786
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000787- Bug #1535165: fixed a segfault in input() and raw_input() when
788 sys.stdin is closed.
789
Thomas Heller74d36f02006-08-04 18:17:40 +0000790- On Windows, the PyErr_Warn function is now exported from
791 the Python dll again.
792
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000793- Bug #1191458: tracing over for loops now produces a line event
794 on each iteration. Fixing this problem required changing the .pyc
795 magic number. This means that .pyc files generated before 2.5c1
796 will be regenerated.
797
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000798- Bug #1333982: string/number constants were inappropriately stored
799 in the byte code and co_consts even if they were not used, ie
800 immediately popped off the stack.
801
Georg Brandle9462c72006-08-04 18:03:37 +0000802- Fixed a reference-counting problem in property().

805Library
806-------
807
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000808- Fix a bug in the ``compiler`` package that caused invalid code to be
809 generated for generator expressions.
810
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000811- The distutils version has been changed to 2.5.0. The change to
812 keep it programmatically in sync with the Python version running
813 the code (introduced in 2.5b3) has been reverted. It will continue
814 to be maintained manually as static string literal.
815
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000816- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000817 and this cannot be converted to the required C type, an exception is
818 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000819 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000820
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000821- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000822 an exception.
823
Tim Petersc10c9d02006-09-05 02:18:09 +0000824- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000825 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000826 workarounds for clocks with low resolution, to stop the code yielding
827 duplicate UUIDs.
828
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000829- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
830 before raising SystemExit, allowing IDLE to honor quit() and exit().
831
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000832- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
833
Georg Brandl7a1af772006-08-14 21:55:28 +0000834- Patch #1536071: trace.py should now find the full module name of a
835 file correctly even on Windows.
836
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000837- logging's atexit hook now runs even if the rest of the module has
838 already been cleaned up.
839
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000840- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000841
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000842- Bug #1531405, format_exception no longer raises an exception if
843 str(exception) raised an exception.
844
Neil Schemenauer06ded092006-08-04 16:20:30 +0000845- Fix a bug in the ``compiler`` package that caused invalid code to be
846 generated for nested functions.

859
Thomas Heller86720042006-08-14 11:17:48 +0000860- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
861 uses the _as_parameter_ attribute when objects are passed to foreign
862 function calls. The ctypes version number was changed to 1.0.1.
863
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000864- Bug #1530559, struct.pack raises TypeError where it used to convert.
865 Passing float arguments to struct.pack when integers are expected
866 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000903- New API for Unicode rich comparisons: PyUnicode_RichCompare()
904
Tim Peters4643c2f2006-08-10 22:45:34 +0000905- Bug #1069160. Internal correctness changes were made to
906 ``PyThreadState_SetAsyncExc()``. A test case was added, and
907 the documentation was changed to state that the return value
908 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +0000913
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000914*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000915
916Core and builtins
917-----------------
918
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000919- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000920 returned a long (see PEP 353).
921
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000922- Bug #1515471: string.replace() accepts character buffers again.
923
Neal Norwitz07aadb12006-07-30 06:55:48 +0000924- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
925 This provides the proper warning for struct.pack().
926 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
927
Neal Norwitz0d62a062006-07-30 06:53:31 +0000928- Patch #1531113: Fix augmented assignment with yield expressions.
929 Also fix a SystemError when trying to assign to yield expressions.
930
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000931- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
932 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
933 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
934 excessive filesystem operations during imports.
935
Tim Petersbc24eee2006-07-27 01:14:53 +0000936- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
937 operations on signed longs that are formally undefined by C.
938 Unfortunately, at least one compiler now cares about that, so complicated
939 the code to make that compiler happy again.
940
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000941- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
942
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000943- Patch #1232023: Stop including current directory in search
944 path on Windows.
945
Neal Norwitze1fdb322006-07-21 05:32:28 +0000946- Fix some potential crashes found with failmalloc.
947
Neal Norwitze7563102006-07-17 01:00:16 +0000948- Fix warnings reported by Klocwork's static analysis tool.
949
Neal Norwitz84be93b2006-07-16 01:50:38 +0000950- Bug #1512814, Fix incorrect lineno's when code within a function
951 had more than 255 blank lines.
952
Georg Brandl9dceedb2006-07-12 15:31:17 +0000953- Patch #1521179: Python now accepts the standard options ``--help`` and
954 ``--version`` as well as ``/?`` on Windows.
955
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000956- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000957 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000958 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000959
Tim Peters112aad32006-07-19 00:03:19 +0000960- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000961 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000962 new ``sys._current_frames()`` returns a dictionary with one entry,
963 mapping the faux "thread id" 0 to the current frame.
964
Ronald Oussoren3075e162006-07-25 20:28:55 +0000965- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000966

969-------
970
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000971- Correction of patch #1455898: In the mbcs decoder, set final=False
972 for stream decoder, but final=True for the decode function.
973
Georg Brandl07fec3a2006-08-01 18:49:24 +0000974- os.urandom no longer masks unrelated exceptions like SystemExit or
975 KeyboardInterrupt.
976
Tim Peters4643c2f2006-08-10 22:45:34 +0000977- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000978 shutil.copytree on Windows
979
Georg Brandle34ac7c2006-07-30 11:07:23 +0000980- Bug #1002398: The documentation for os.path.sameopenfile now correctly
981 refers to file descriptors, not file objects.
982
Tim Petersc10c9d02006-09-05 02:18:09 +0000983- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000984 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000985 #1513611, and probably others.
986
Georg Brandledd9b0d2006-07-29 09:33:26 +0000987- Bug #1441397: The compiler module now recognizes module and function
988 docstrings correctly as it did in Python 2.4.
989
Tim Peters6f681472006-07-27 23:44:37 +0000990- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
991 lost that tests are sorted by name before being run. This rarely
992 matters for well-written tests, but can create baffling symptoms if
993 side effects from one test to the next affect outcomes. ``DocTestFinder``
994 has been changed to sort the list of tests it returns.
995
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000996- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000997 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000998
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000999- Bug #978833: Really close underlying socket in _socketobject.close.
1000
Georg Brandl8c036cc2006-08-20 13:15:39 +00001001- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1002 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001003
Georg Brandlcf0c1722006-07-26 07:23:32 +00001004- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1005 to recursive calls and call it with the failing package name.
1006
Martin v. Löwis0b483032006-07-25 09:53:12 +00001007- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1008
Georg Brandlc13c34c2006-07-24 14:09:56 +00001009- Patch #1515343: Fix printing of deprecated string exceptions with a
1010 value in the traceback module.
1011
Greg Ward48fae7a2006-07-23 16:05:51 +00001012- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1013
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001014- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1015
Brett Cannoncaebe222006-07-18 04:41:36 +00001016- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1017 argument tuple. For arguments where zero is illegal, the value is forced to
1018 the minimum value that is correct. This is to support an undocumented but
1019 common way people used to fill in inconsequential information in the time
1020 tuple pre-2.4.
1021
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001022- Patch #1220874: Update the binhex module for Mach-O.
1023
Barry Warsawb110bad2006-07-21 14:51:07 +00001024- The email package has improved RFC 2231 support, specifically for
1025 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1026 (name*0=<blah>) parameter continuations. This may change the types of
1027 values returned from email.message.Message.get_param() and friends.
1028 Specifically in some cases where non-encoded continuations were used,
1029 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1030 will just return the string (since non-encoded continuations don't have
1031 charset and language parts).
1032
1033 Also, whereas % values were decoded in all parameter continuations, they are
1034 now only decoded in encoded parameter parts.
1035
Ronald Oussoren3075e162006-07-25 20:28:55 +00001036- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1037
1038- Bug #1517996: IDLE now longer shows the default Tk menu when a
1039 path browser, class browser or debugger is the frontmost window on MacOS X
1040
Barry Warsaw00decd72006-07-27 23:43:15 +00001041- Patch #1520294: Support for getset and member descriptors in types.py,
1042 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1043 of an object against these built-in types and more importantly, for getting
1044 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001047Extension Modules
1048-----------------
1049
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001050- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1051 a socket operation on a socket with a timeout, the exception will be
1052 caught correctly. Previously, the exception was not caught.
1053
Thomas Heller1393d6a2006-07-28 21:43:20 +00001054- Patch #1529514: The _ctypes extension is now compiled on more
1055 openbsd target platforms.
1056
Tim Peters9cab5932006-07-28 00:30:00 +00001057- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1058 a memory leak, affecting pickles and deep copies.
1059
Tim Petersbc24eee2006-07-27 01:14:53 +00001060- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001061 Paul Eggert.
1062
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001063- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1064
Thomas Hellerce049a02006-07-14 17:51:14 +00001065- Patch #1521817: Index range checking on ctypes arrays containing
1066 exactly one element enabled again. This allows iterating over these
1067 arrays, without the need to check the array size before.
1068
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001069- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001070 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001071 /dev/null in certain cases; this is now fixed.
1072
Thomas Heller47d7a062006-07-12 08:43:47 +00001073- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1074 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001075
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001076- Because of a misspelled preprocessor symbol, ctypes was always
1077 compiled without thread support; this is now fixed.
1078
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001079- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1080 methods now allow their database parameter to be None as the
1081 sleepycat API allows.
1082
Matt Flemingec926502006-07-28 11:27:27 +00001083- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1084 bluetooth API compared with Linux and FreeBSD.
1085
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001086Tests
1087-----
1088
1089- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1090 how long the test file should take to play. Now accepts taking 2.93 secs
1091 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1092
Georg Brandl4793aa32006-07-28 18:31:39 +00001093- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1094 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1095 run via ``regrtest.py``. Now they do.

1104
1105- PythonLauncher now works correctly when the path to the script contains
1106 characters that are treated specially by the shell (such as quotes).
1107
1108- Bug #1527397: PythonLauncher now launches scripts with the working directory
1109 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001110 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001111 expect.

1121
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001122- Bug #1441486: The literal representation of -(sys.maxint - 1)
1123 again evaluates to a int object, not a long.
1124
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001125- Bug #1501934: The scope of global variables that are locally assigned
1126 using augmented assignment is now correctly determined.
1127
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001128- Bug #927248: Recursive method-wrapper objects can now safely
1129 be released.
1130
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001131- Bug #1417699: Reject locale-specific decimal point in float()
1132 and atof().
1133
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001134- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1135 omit a default "error" argument for NULL pointer. This allows
1136 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001137
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001138- Bug #1519018: 'as' is now validated properly in import statements.
1139
Neal Norwitz28746ab2006-07-09 22:14:42 +00001140- On 64 bit systems, int literals that use less than 64 bits are
1141 now ints rather than longs.
1142
Neal Norwitzed657552006-07-10 00:04:44 +00001143- Bug #1512814, Fix incorrect lineno's when code at module scope
1144 started after line 256.
1145
Tim Peters32a83612006-07-10 21:08:24 +00001146- New function ``sys._current_frames()`` returns a dict mapping thread
1147 id to topmost thread stack frame. This is for expert use, and is
1148 especially useful for debugging application deadlocks. The functionality
1149 was previously available in Fazal Majid's ``threadframe`` extension
1150 module, but it wasn't possible to do this in a wholly threadsafe way from
1151 an extension.

Martin v. Löwis06c68b82006-07-10 22:11:28 +00001159- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1160
Tim Peters32a83612006-07-10 21:08:24 +00001161- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001162 environment variable to be set in order to the SDK environment

1168
Thomas Woutersadd19112006-07-05 11:03:49 +00001169- string.Template() now correctly handles tuple-values. Previously,
1170 multi-value tuples would raise an exception and single-value tuples would
1171 be treated as the value they contain, instead.
1172
Martin v. Löwisede77f52006-07-03 13:01:35 +00001173- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1180 degrees and radians.
1181
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001182- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001183 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001184

Martin v. Löwis7596e832006-07-01 15:33:37 +00001188- Bug #1513223: .close() of a _socketobj now releases the underlying
1189 socket again, which then gets closed as it becomes unreferenced.
1190

1192 attribute values.
1193
1194- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1195 sgmllib ('[' and ']' were not accepted).
1196

1198
Brett Cannon53ab5b72006-06-22 16:49:14 +00001199- Bug #1510580: The 'warnings' module improperly required that a Warning
1200 category be either a types.ClassType and a subclass of Warning. The proper
1201 check is just that it is a subclass with Warning as the documentation states.
1202
Georg Brandlad29e632006-06-21 17:45:17 +00001203- The compiler module now correctly compiles the new try-except-finally
1204 statement (bug #1509132).
1205

1209 shutdown when fileConfig() was called multiple times.
1210
Gerhard Häring762fbd32006-07-02 17:48:30 +00001211- The sqlite3 module did cut off data from the SQLite database at the first
1212 null character before sending it to a custom converter. This has been fixed
1213 now.
1214
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001215Extension Modules
1216-----------------
1217
Tim Peters112aad32006-07-19 00:03:19 +00001218- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1219 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1220 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001221
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001222- Assigning None to pointer type fields in ctypes structures possible
1223 overwrote the wrong fields, this is fixed now.
1224
1225- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1226 on non-Windows platforms.
1227
1228- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1229 integer or long, without range checking.
1230
1231- Patch #1517790: It is now possible to use custom objects in the ctypes
1232 foreign function argtypes sequence as long as they provide a from_param
1233 method, no longer is it required that the object is a ctypes type.
1234
1235- The '_ctypes' extension module now works when Python is configured
1236 with the --without-threads option.
1237
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001238- Bug #1513646: os.access on Windows now correctly determines write
1239 access, again.
1240
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001241- Bug #1512695: cPickle.loads could crash if it was interrupted with

Neal Norwitza12aa882006-07-06 06:45:08 +00001244- Bug #1296433: parsing XML with a non-default encoding and
1245 a CharacterDataHandler could crash the interpreter in pyexpat.
1246

1253
Tim Peters32a83612006-07-10 21:08:24 +00001254- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001255 Previously, the slight difference could cause compilation errors of the
1256 'zlib' module on systems with more than one version of zlib.
1257
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001258- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001288
1289Core and builtins
1290-----------------
1291
Georg Brandla56b9152006-06-19 06:35:54 +00001292- Patch #1507676: Error messages returned by invalid abstract object operations
1293 (such as iterating over an integer) have been improved and now include the
1294 type of the offending object to help with debugging.
1295
Brett Cannonea3912b2006-06-13 21:46:41 +00001296- Bug #992017: A classic class that defined a __coerce__() method that returned
1297 its arguments swapped would infinitely recurse and segfault the interpreter.
1298
Neal Norwitz909eb122006-06-12 02:13:21 +00001299- Fix the socket tests so they can be run concurrently.
1300
Neal Norwitzb9845e72006-06-12 02:11:18 +00001301- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001302 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001303
Brett Cannon22565aa2006-06-09 22:31:23 +00001304- Bug #532646: object.__call__() will continue looking for the __call__
1305 attribute on objects until one without one is found. This leads to recursion
1306 when you take a class and set its __call__ attribute to an instance of the
1307 class. Originally fixed for classic classes, but this fix is for new-style.
1308 Removes the infinite_rec_3 crasher.
1309
Georg Brandl24250812006-06-09 18:45:48 +00001310- The string and unicode methods startswith() and endswith() now accept
1311 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1312
Brett Cannonde3b0522006-06-08 17:00:45 +00001313- Buffer objects, at the C level, never used the char buffer
1314 implementation even when the char buffer for the wrapped object was
1315 explicitly requested (originally returned the read or write buffer).
1316 Now a TypeError is raised if the char buffer is not present but is
1317 requested.
1318
Georg Brandlddbaa662006-06-04 21:56:52 +00001319- Patch #1346214: Statements like "if 0: suite" are now again optimized
1320 away like they were in Python 2.4.
1321
Georg Brandlb7c8f542006-05-27 12:30:25 +00001322- Builtin exceptions are now full-blown new-style classes instead of
1323 instances pretending to be classes, which speeds up exception handling
1324 by about 80% in comparison to 2.5a2.
1325
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001326- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1327 Unicode 4.1.
1328
Georg Brandlf4ef1162006-05-26 18:03:31 +00001329- Patch #921466: sys.path_importer_cache is now used to cache valid and
1330 invalid file paths for the built-in import machinery which leads to
1331 fewer open calls on startup.
1332
Tim Peters696cf432006-05-24 21:10:40 +00001333- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1334 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1335 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1336 the number of input digits (it was and remains linear-time for bases
1337 2, 4, 8, 16 and 32).
1338
Tim Petersb713ec22006-05-23 18:45:30 +00001339- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1340 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1341 an integer close to ``sys.maxint``. This was repaired by patch
1342 #1335972, which also gives a nice speedup.
1343
Richard Jonescebbefc2006-05-23 18:28:17 +00001344- Patch #1337051: reduced size of frame objects.
1345
1346- PyErr_NewException now accepts a tuple of base classes as its
1347 "base" parameter.
1348
Richard Jones7c88dcc2006-05-23 10:37:38 +00001349- Patch #876206: function call speedup by retaining allocated frame
1350 objects.
1351
Georg Brandl7b90e162006-05-18 07:01:27 +00001352- Bug #1462152: file() now checks more thoroughly for invalid mode
1353 strings and removes a possible "U" before passing the mode to the
1354 C library function.
1355
Neal Norwitz1004a532006-05-15 07:17:23 +00001356- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1357
Neal Norwitz373f0a72006-05-15 07:04:36 +00001358- Bug #1487966: Fix SystemError with conditional expression in assignment
1359
Martin v. Löwis879768d2006-05-11 13:28:43 +00001360- WindowsError now has two error code attributes: errno, which carries
1361 the error values from errno.h, and winerror, which carries the error
1362 values from winerror.h. Previous versions put the winerror.h values
1363 (from GetLastError()) into the errno attribute.
1364
Martin v. Löwis77736712006-05-04 05:51:03 +00001365- Patch #1475845: Raise IndentationError for unexpected indent.
1366
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001367- Patch #1479181: split open() and file() from being aliases for each other.
1368
Tim Peters44bd9862006-06-01 13:49:23 +00001369- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1370 methods were always silently ignored by dictionaries when comparing keys.
1371 They are now passed through (except when using the C API function
1372 ``PyDict_GetItem()``, whose semantics did not change).
1373
1374- Bug #1456209: In some obscure cases it was possible for a class with a
1375 custom ``__eq__()`` method to confuse dict internals when class instances
1376 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1377 No, you don't have any code that did this ;-)

1385
Brett Cannon6ee7d012006-06-08 16:23:04 +00001386- Change binascii.hexlify to accept a read-only buffer instead of only a char
1387 buffer and actually follow its documentation.
1388
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001389- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1390
Nick Coghlanc649ec52006-05-29 12:43:05 +00001391- Patch #1478788 (modified version): The functional extension module has
1392 been renamed to _functools and a functools Python wrapper module added.
1393 This provides a home for additional function related utilities that are
1394 not specifically about functional programming. See PEP 309.
1395
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001396- Patch #1493701: performance enhancements for struct module.

1401 copy() method.
1402
Andrew MacIntyre92913322006-06-13 15:04:24 +00001403- Patch #1454481: thread stack size is now tunable at runtime for thread
1404 enabled builds on Windows and systems with Posix threads support.
1405
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001406- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1407 (up to the system limit of 32K characters).
1408
1409- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1410 As a result, these functions now raise WindowsError instead of OSError.
1411
Tim Peters7a822da2006-05-25 21:50:17 +00001412- ``time.clock()`` on Win64 should use the high-performance Windows
1413 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1414 Windows platforms).
1415
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001416- Calling Tk_Init twice is refused if the first call failed as that
1417 may deadlock.
1418
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001419- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1420 accept it without potentially using an uninitialized pointer.
1421
1422- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1423 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1424 patch numbers 1494885 and 1494902]

1431
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001432- bsddb: the __len__ method of a DB object has been fixed to return correct
1433 results. It could previously incorrectly return 0 in some cases.
1434 Fixes SF bug 1493322 (pybsddb bug 1184012).
1435
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001436- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1437 aborts the db transaction safely when a modifier callback fails.
1438 Fixes SF python patch/bug #1408584.
1439
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001440- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001441 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001442 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1443 database calls that would previously deadlock. [SF python bug #775414]
1444

Georg Brandl2605ca82006-06-14 06:08:31 +00001469- Bug #1339007: Shelf objects now don't raise an exception in their
1470 __del__ method when initialization failed.
1471
Martin v. Löwisd8251432006-06-14 05:21:04 +00001472- Patch #1455898: The MBCS codec now supports the incremental mode for
1473 double-byte encodings.
1474
Tim Peters43898b42006-06-14 04:09:25 +00001475- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1476 guarantee that adjacent triples in the return list always describe
1477 non-adjacent blocks. Previously, a pair of matching blocks could end
1478 up being described by multiple adjacent triples that formed a partition
1479 of the matching pair.
1480
Greg Ward0e0c9f42006-06-11 16:24:11 +00001481- Bug #1498146: fix optparse to handle Unicode strings in option help,
1482 description, and epilog.
1483
Greg Wardd1c797e2006-06-11 14:42:41 +00001484- Bug #1366250: minor optparse documentation error.
1485
Greg Ward7f547402006-06-11 00:40:49 +00001486- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1487 clarify docs.
1488
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001489- The wsgiref package has been added to the standard library.
1490
Nick Coghlan676725d2006-06-08 13:54:49 +00001491- The functions update_wrapper() and wraps() have been added to the functools
1492 module. These make it easier to copy relevant metadata from the original
1493 function when writing wrapper functions.
1494
Tim Petersd6a9eef2006-06-05 01:48:21 +00001495- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1496 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001497
Martin v. Löwis3f767792006-06-04 19:36:28 +00001498- Patch #1359618: Speed up charmap encoder by using a trie structure
1499 for lookup.
1500
Tim Petersd609b1a2006-06-02 23:22:51 +00001501- The functions in the ``pprint`` module now sort dictionaries by key
1502 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1503 if and only if its display required more than one line, although that
1504 wasn't documented. The new behavior increases predictability; e.g.,
1505 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1506
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001507- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1508 (thanks for J. J. Lee).
1509
Georg Brandl2b330372006-05-28 20:23:12 +00001510- Patch #1496206: improve urllib2 handling of passwords with respect to
1511 default HTTP and HTTPS ports.
1512
George Yoshidaf3c65de2006-05-28 16:39:09 +00001513- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1514
Bob Ippolito7298f272006-05-23 18:43:47 +00001515- Patch #1281707: speed up gzip.readline.
1516
Georg Brandlb89316f2006-05-17 15:51:16 +00001517- Patch #1180296: Two new functions were added to the locale module:
1518 format_string() to get the effect of "format % items" but locale-aware,
1519 and currency() to format a monetary number with currency sign.
1520
Georg Brandle3a25832006-05-17 14:56:04 +00001521- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1522 and several features added, such as speed and geometry control.
1523
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001524- Patch #1488881: add support for external file objects in bz2 compressed
1525 tarfiles.
1526
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001527- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1528 stdout arguments, making it possible to redirect input and output
1529 for remote debugging.
1530
1531- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1532 a couple of issues, notably handling of long file names using the
1533 GNU LONGNAME extension.
1534
1535- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1536 new flag when ``name`` is already the name of an option flag.
1537
1538- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1539 package.
1540
1541- Patch #1472854: make the rlcompleter.Completer class usable on non-
1542 UNIX platforms.
1543
1544- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1545
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001546- Bug #1472827: correctly escape newlines and tabs in attribute values in
1547 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001577What's New in Python 2.5 alpha 2?
1578=================================
1579
1580*Release date: 27-APR-2006*
1581
1582Core and builtins
1583-----------------
1584
Thomas Heller1b046642006-04-18 18:51:06 +00001585- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1586 by converting these apis from macros into exported functions again:
1587
1588 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1589 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1590 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1591 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1592 PyRun_String Py_CompileString
1593
Martin v. Löwis45294a92006-04-18 06:24:08 +00001594- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1595
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001596- All uses of PyStructSequence_InitType have been changed to initialize
1597 the type objects only once, even if the interpreter is initialized
1598 multiple times.
1599
Neal Norwitz61546162006-04-14 05:20:28 +00001600- Bug #1454485, array.array('u') could crash the interpreter. This was
1601 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1602 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1603
1604- Py_UNICODE is unsigned. It was always documented as unsigned, but
1605 due to a bug had a signed value in previous versions.
1606
Tim Peters3a5e8b12006-04-11 01:44:07 +00001607- Patch #837242: ``id()`` of any Python object always gives a positive
1608 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1609 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001610 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001611 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001612
Tim Peters3a5e8b12006-04-11 01:44:07 +00001613 def __hash__(self):
1614 return id(self) # WRONG
1615
1616 because a hash result must be a (short) Python int but it was always
1617 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001618 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001619 was always usable as a hash value before this patch. That's no longer
1620 necessarily so.
1621
1622- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001623 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001624 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001625 #1454844)
1626
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001627- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1628 involving generators that have paused outside of any ``try`` or ``with``
1629 blocks. (In 2.5a1, a paused generator that was part of a reference
1630 cycle could not be garbage collected, regardless of whether it was
1631 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001632
Anthony Baxter51bcb682006-04-05 14:51:42 +00001633Extension Modules
1634-----------------
1635
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001636- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1637 is a macro.
1638
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001639- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1640 fails with an error condition.
1641
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001642- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1643
1644- Bug #1117761: bsddb.*open() no longer raises an exception when using
1645 the cachesize parameter.
1646
1647- Bug #1149413: bsddb.*open() no longer raises an exception when using
1648 a temporary db (file=None) with the 'n' flag to truncate on open.
1649
1650- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1651 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001652
Armin Rigoa9017c32006-04-19 11:50:27 +00001653- Patch #1062014: AF_UNIX sockets under Linux have a special
1654 abstract namespace that is now fully supported.

1657-------
1658
Peter Astrand7d1d4362006-07-14 14:04:45 +00001659- Bug #1223937: subprocess.CalledProcessError reports the exit status
1660 of the process using the returncode attribute, instead of
1661 abusing errno.
1662
Tim Peters711bf302006-04-25 03:31:36 +00001663- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1664 a doctest to be skipped (the code is not run, and the expected output
1665 or exception is ignored).
1666
Nick Coghlanda2268f2006-04-24 04:37:15 +00001667- Fixed contextlib.nested to cope with exceptions being raised and
1668 caught inside exit handlers.
1669
Greg Wardab05edc2006-04-23 03:47:58 +00001670- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1671 hex, octal, or binary; add ``append_const`` action; keep going if
1672 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1673 added ``epilog`` for better help generation).
1674
Tim Peters21fbd572006-04-21 21:18:10 +00001675- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1676 called from a thread spawned as a side effect of importing a module.
1677
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001678- The pydoc module now supports documenting packages contained in
1679 .zip or .egg files.
1680
1681- The pkgutil module now has several new utility functions, such
1682 as ``walk_packages()`` to support working with packages that are either
1683 in the filesystem or zip files.
1684
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001685- The mailbox module can now modify and delete messages from
1686 mailboxes, in addition to simply reading them. Thanks to Gregory
1687 K. Johnson for writing the code, and to the 2005 Google Summer of
1688 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001689
Tim Petersc7605f22006-04-17 21:12:33 +00001690- The ``__del__`` method of class ``local`` in module ``_threading_local``
1691 returned before accomplishing any of its intended cleanup.
1692
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001693- Patch #790710: Add breakpoint command lists in pdb.
1694
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001695- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1698
Anthony Baxtere29002c2006-04-12 12:07:31 +00001699- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1700 Windows. Bug #1469163.
1701
Phillip J. Eby47032112006-04-11 01:07:43 +00001702- The warnings, linecache, inspect, traceback, site, and doctest modules
1703 were updated to work correctly with modules imported from zipfiles or
1704 via other PEP 302 __loader__ objects.
1705
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001706- Patch #1467770: Reduce usage of subprocess._active to processes which
1707 the application hasn't waited on.

1714 direct output to an alternate file-like object.
1715
Anthony Baxter51bcb682006-04-05 14:51:42 +00001716Build
1717-----
1718
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001719- The Makefile now has a reindent target, which runs reindent.py on
1720 the library.
1721
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001722- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001726- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1727 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001728 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001729 CXX from --with-cxx-main, see description in README.
1730
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001731- Patch #1429775: Link extension modules with the shared libpython.
1732
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001733- Fixed a libffi build problem on MIPS systems.
1734
Tim Peters8931ff12006-05-13 23:28:20 +00001735- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1736 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1737 and "%zu" for unsigned integers of type ``size_t``.
1738
Anthony Baxter51bcb682006-04-05 14:51:42 +00001739Tests
1740-----
1741
Nick Coghlanda2268f2006-04-24 04:37:15 +00001742- test_contextlib now checks contextlib.nested can cope with exceptions
1743 being raised and caught inside exit handlers.
1744
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001745- test_cmd_line now checks operation of the -m and -c command switches
1746
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001747- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1748 it separately and by hand. It also wasn't cleaning up its changes to
1749 the current Decimal context.
1750
Thomas Woutersabd08882006-04-26 15:53:30 +00001751- regrtest.py now has a -M option to run tests that test the new limits of
1752 containers, on 64-bit architectures. Running these tests is only sensible
1753 on 64-bit machines with more than two gigabytes of memory. The argument
1754 passed is the maximum amount of memory for the tests to use.

1766
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001767- PEP 343: Added Context Types section to the library reference
1768 and attempted to bring other PEP 343 related documentation into
1769 line with the implementation and/or python-dev discussions.
1770
Tim Peters8dc73d22006-04-24 02:03:16 +00001771- Bug #1337990: clarified that ``doctest`` does not support examples

1781-----------------
1782
Nick Coghlan43832302006-04-23 17:04:07 +00001783- PEP 338: -m command line switch now delegates to runpy.run_module
1784 allowing it to support modules in packages and zipfiles
1785
Martin v. Löwisc661b882006-04-20 04:54:23 +00001786- On Windows, .DLL is not an accepted file name extension for
1787 extension modules anymore; extensions are only found if they
1788 end in .PYD.
1789
Martin v. Löwisea62d252006-04-03 10:56:49 +00001790- Bug #1421664: sys.stderr.encoding is now set to the same value as
1791 sys.stdout.encoding.
1792
Neal Norwitz92e212f2006-04-03 04:48:37 +00001793- __import__ accepts keyword arguments.
1794
Georg Brandlccadf842006-03-31 18:54:53 +00001795- Patch #1460496: round() now accepts keyword arguments.
1796
Anthony Baxter262c00a2006-03-30 10:53:17 +00001797- Fixed bug #1459029 - unicode reprs were double-escaped.
1798
Hye-Shik Changd478f342006-03-23 12:32:36 +00001799- Patch #1396919: The system scope threads are reenabled on FreeBSD
1800 5.4 and later versions.
1801
Neal Norwitze98ccf62006-03-23 05:39:47 +00001802- Bug #1115379: Compiling a Unicode string with an encoding declaration
1803 now gives a SyntaxError.
1804
Georg Brandlabd1ff82006-03-18 07:59:59 +00001805- Previously, Python code had no easy way to access the contents of a
1806 cell object. Now, a ``cell_contents`` attribute has been added
1807 (closes patch #1170323).
1808
Tim Peterscf79aac2006-03-16 01:14:46 +00001809- Patch #1123430: Python's small-object allocator now returns an arena to
1810 the system ``free()`` when all memory within an arena becomes unused
1811 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1812 freed. Some applications will see a drop in virtual memory size now,
1813 especially long-running applications that, from time to time, temporarily
1814 use a large number of small objects. Note that when Python returns an
1815 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001816 platform C library will in turn return that memory to the operating system.
1817 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001818 appears to be effective at least on Microsoft C and gcc-based systems.
1819 Thanks to Evan Jones for hard work and patience.
1820
Georg Brandl533ff6f2006-03-08 18:09:27 +00001821- Patch #1434038: property() now uses the getter's docstring if there is
1822 no "doc" argument given. This makes it possible to legitimately use
1823 property() as a decorator to produce a read-only property.
1824
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001825- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1826 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1827 of requiring an int or long in slicing and a few other contexts, enabling
1828 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1829
Neal Norwitz995acdf2006-03-07 05:01:00 +00001830- Fixed various bugs reported by Coverity's Prevent tool.
1831
Brett Cannonbf364092006-03-01 04:25:17 +00001832- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1833 new exception base class, BaseException, which has a new message attribute.
1834 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1835 Raising a string exception now raises a DeprecationWarning.
1836
Thomas Woutersfb609f42006-02-28 16:37:25 +00001837- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1838 explicitly relative, using 'from .module import name' to mean 'from the same
1839 package as this module is in. Imports without dots still default to the
1840 old relative-then-absolute, unless 'from __future__ import
1841 absolute_import' is used.
1842
Brett Cannona7446e32006-02-27 23:39:10 +00001843- Properly check if 'warnings' raises an exception (usually when a filter set
1844 to "error" is triggered) when raising a warning for raising string
1845 exceptions.
1846
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001847- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001848 The name was removed from Include/code.h.
1849
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001850- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001851
Guido van Rossum1968ad32006-02-25 22:38:04 +00001852- Patch 1433928:
1853 - The copy module now "copies" function objects (as atomic objects).
1854 - dict.__getitem__ now looks for a __missing__ hook before raising
1855 KeyError.
1856
Tim Peters84ef21c2006-02-28 20:39:06 +00001857- PEP 343: with statement implemented. Needs ``from __future__ import
1858 with_statement``. Use of 'with' as a variable will generate a warning.
1859 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001860 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001861 The following objects have __context__ methods:
1862 - The built-in file type.
1863 - The thread.LockType type.
1864 - The following types defined by the threading module:
1865 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1866 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001867
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001868- Fix the encodings package codec search function to only search
1869 inside its own package. Fixes problem reported in patch #1433198.
1870
1871 Note: Codec packages should implement and register their own
1872 codec search function. PEP 100 has the details.
1873
Tim Peters9ea89d22006-06-04 03:26:02 +00001874- PEP 353: Using ``Py_ssize_t`` as the index type.
1875
1876- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1877 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1878 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1879 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1880 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001881
Neal Norwitzfc76d632006-01-10 06:03:13 +00001882- Patch #1400181, fix unicode string formatting to not use the locale.
1883 This is how string objects work. u'%f' could use , instead of .
1884 for the decimal point. Now both strings and unicode always use periods.
1885
Neal Norwitz671b9e32006-01-09 07:07:12 +00001886- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1887 configure would break checking curses.h.
1888
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001889- Bug #959576: The pwd module is now builtin. This allows Python to be
1890 built on UNIX platforms without $HOME set.
1891
Neal Norwitzc10978f2005-12-19 06:07:16 +00001892- Bug #1072182, fix some potential problems if characters are signed.
1893
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001894- Bug #889500, fix line number on SyntaxWarning for global declarations.
1895
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001896- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1897
Neal Norwitze7214a12005-12-18 05:03:17 +00001898- Support for converting hex strings to floats no longer works.
1899 This was not portable. float('0x3') now raises a ValueError.
1900
Barry Warsaw2a38a862005-12-18 01:27:35 +00001901- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001902 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001903 is now displayed in interactive prompt banner.
1904
Georg Brandlfa166682005-12-17 21:45:17 +00001905- Implementation of PEP 341 - Unification of try/except and try/finally.
1906 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001907 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001908
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001909- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1910 now encodes backslash correctly.
1911
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001912- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1913
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001914- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001915 and long longs.
1916
Neal Norwitz67715f02005-11-09 06:59:35 +00001917- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001918 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001919 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001920
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001921- Replaced most Unicode charmap codecs with new ones using the
1922 new Unicode translate string feature in the builtin charmap
1923 codec; the codecs were created from the mapping tables available
1924 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1925 encodings now include a mapping for the Apple logo)
1926
Tim Peterse3547fd2005-12-16 23:13:57 +00001927- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001928
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001929- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001930
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001931- A new AST parser implementation was completed. The abstract
1932 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001933 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001934
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001935- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001936 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1937
Neal Norwitz708e51a2005-10-03 04:48:15 +00001938- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1939
Neal Norwitz11bd1192005-10-03 00:54:56 +00001940- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1941 Provide a warning when a directory is passed on the command line.
1942
Neal Norwitz40d37812005-10-02 01:48:49 +00001943- Fix segfault with invalid coding.
1944
1945- SF bug #772896: unknown encoding results in MemoryError.
1946
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001947- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001948 supported a __len__() method which evaluated to False when the iterator
1949 was empty.
1950
Guido van Rossum630db602005-09-20 18:49:54 +00001951- On 64-bit platforms, when __len__() returns a value that cannot be
1952 represented as a C int, raise OverflowError.
1953
Skip Montanarof8948ca2005-09-19 03:54:46 +00001954- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001955 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001956
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001957- SF bug #893549: parsing keyword arguments was broken with a few format
1958 codes.
1959
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001960- Changes donated by Elemental Security to make it work on AIX 5.3
1961 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1962 bug #105470: test_pwd fails on 64bit system (Opteron).
1963
Guido van Rossum539c6622005-09-14 17:49:54 +00001964- Changes donated by Elemental Security to make it work on HP-UX 11 on
1965 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1966
Georg Brandl4550b8d2005-08-26 06:43:52 +00001967- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001968 (fixes bug #1119418).
1969
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001970- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1971
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001972- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1973 exceptions that cause a function to exit.
1974
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001975- The implementation of set() and frozenset() was revised to use its
1976 own internal data structure. Memory consumption is reduced by 1/3
1977 and there are modest speed-ups as well. The API is unchanged.
1978
Tim Petersde7990b2005-07-17 23:45:23 +00001979- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1980
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001981- SF bug #1229429: PyObject_CallMethod failed to decrement some
1982 reference counts in some error exit cases.
1983
Tim Petersecc6e6a2005-07-10 22:30:55 +00001984- SF bug #1185883: Python's small-object memory allocator took over
1985 a block managed by the platform C library whenever a realloc specified
1986 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001987 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001988 portable way to copy data from the C-managed block into Python's
1989 small-object space without risking a memory fault. Python's small-object
1990 realloc now leaves such blocks under the control of the platform C
1991 realloc.
1992
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001993- SF bug #1232517: An overflow error was not detected properly when
1994 attempting to convert a large float to an int in os.utime().
1995
Raymond Hettinger3296e692005-06-29 23:29:56 +00001996- SF bug #1224347: hex longs now print with lowercase letters just
1997 like their int counterparts.
1998
Michael W. Hudson188d4362005-06-20 16:52:57 +00001999- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2000 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2001 interpreter states; back out that fix and do a better job (see
2002 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2003 for a longer write-up of the problem).
2004
Michael W. Hudsondf888462005-06-03 14:41:55 +00002005- SF patch #1180995: marshal now uses a binary format by default when
2006 serializing floats.
2007
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002008- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2009 the routines that promise to produce IEEE 754 binary representations
2010 of floats now simply copy bytes around.
2011
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002012- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2013 278.
2014
Brett Cannonc3647ac2005-04-26 03:45:26 +00002015- patch #1109424: int, long, float, complex, and unicode now check for the
2016 proper magic slot for type conversions when subclassed. Previously the
2017 magic slot was ignored during conversion. Semantics now match the way
2018 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002019 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002020 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002021 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002022
Barry Warsawc8d907c2005-04-19 23:43:40 +00002023- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2024 NULL, now raise an AttributeError when attempting to set or delete the
2025 attribute. Previously a TypeError was raised, but this was inconsistent
2026 with the equivalent pure-Python implementation.
2027
Michael W. Hudson774479c2005-04-18 08:46:17 +00002028- It is now safe to call PyGILState_Release() before
2029 PyEval_InitThreads() (note that if there is reason to believe there
2030 are multiple threads around you still must call PyEval_InitThreads()
2031 before using the Python API; this fix is for extension modules that
2032 have no way of knowing if Python is multi-threaded yet).
2033
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002034- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2035 disabled caused a crash.
2036
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002037- Bug #1165306: instancemethod_new allowed the creation of a method
2038 with im_class == im_self == NULL, which caused a crash when called.
2039
Tim Petersecc6e6a2005-07-10 22:30:55 +00002040- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002041 fixes the crash seen in bug #1165761
2042
Raymond Hettinger96229b12005-03-11 06:49:40 +00002043- Added two new builtins, any() and all().

2086 current thread state when the auto-GIL-state machinery knows about
2087 it (since the thread state is being deleted, continuing to remember it
2088 can't help, but can hurt if another thread happens to get created with
2089 the same thread id).

2297 in attribute values.
2298
Anthony Baxterc51ee692006-04-01 00:57:31 +00002299- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002300 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002301 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002302 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002304- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2305 aren't officially supported here, and trying to use them will probably

2327
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002328- email 4.0 package now integrated. This is largely the same as the email 3.0
2329 package that was included in Python 2.3, except that PEP 8 module names are
2330 now used (e.g. mail.message instead of email.Message). The MIME classes
2331 have been moved to a subpackage (e.g. email.mime.text instead of
2332 email.MIMEText). The old names are still supported for now. Several
2333 deprecated Message methods have been removed and lots of bugs have been
2334 fixed. More details can be found in the email package documentation.

2337 (a subclass of tuple) that provides incremental decoders and encoders
2338 (a way to use stateful codecs without the stream API). Python functions
2339 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2340 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2341 have been added.

2344 a ValueError instead of a StopIteration now (like file and cString.String do).
2345 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2346 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002420 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2421 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2422 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2423 Ronald L. Rivest offered this advice for Python:
2424
2425 "The consensus of researchers in this area (at least as
2426 expressed at the NIST Hash Function Workshop 10/31/05),
2427 is that SHA-256 is a good choice for the time being, but
2428 that research should continue, and other alternatives may
2429 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002430

2587
Raymond Hettingerbab41432005-02-05 01:31:19 +00002588- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2589
Guido van Rossumd0641422005-02-03 15:01:24 +00002590- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2591 disables recursive traversal through instance attributes, which can
2592 be exploited in various ways.
2593
Tim Peterse3547fd2005-12-16 23:13:57 +00002594- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002595 flags on the HTTP listening socket.
2596
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002597- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2598 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2599
Fred Drakefbdeaad2006-07-29 16:56:15 +00002600- Patches #893642, #1039083: add allow_none, encoding arguments to
2601 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002602

2606
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002607- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2608
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002609- Enhancements to the csv module:
2610
2611 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002612 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002613 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002614 + Dialect parameter parsing has been re-implemented to improve error
2615 reporting.
2616 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2617 dictates.
2618 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002619 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002620 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002621 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2622 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002623 + reader now allows \r characters to be quoted (previously it only allowed
2624 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002625 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002626 + Dialect classes passed to the module are no longer instantiated by
2627 the module before being parsed (the former validation scheme required
2628 this, but the mechanism was unreliable).
2629 + The dialect registry now contains instances of the internal
2630 C-coded dialect type, rather than references to python objects.
2631 + the internal c-coded dialect type is now immutable.
2632 + register_dialect now accepts the same keyword dialect specifications
2633 as the reader and writer, allowing the user to register dialects
2634 without first creating a dialect class.
2635 + a configurable limit to the size of parsed fields has been added -
2636 previously, an unmatched quote character could result in the entire
2637 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002638 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002639 the parser field size limit (returning the former limit). The initial
2640 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002641 + A line_num attribute has been added to the reader object, which tracks
2642 the number of lines read from the source iterator. This is not
2643 the same as the number of records returned, as records can span
2644 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002645 + reader and writer objects were not being registered with the cyclic-GC.
2646 This has been fixed.
2647
Brett Cannone6539c42005-01-08 02:43:53 +00002648- _DummyThread objects in the threading module now delete self.__block that is
2649 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2650 lock primitives tend to be limited in number and thus should not be wasted on
2651 a _DummyThread object. Fixes bug #1089632.
2652
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002653- The imghdr module now detects Exif files.
2654
Raymond Hettinger6065d322004-12-20 23:51:53 +00002655- StringIO.truncate() now correctly adjusts the size attribute.
2656 (Bug #951915).
2657
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002658- locale.py now uses an updated locale alias table (built using
2659 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2660 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002661 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002662
Raymond Hettinger3557f422004-12-07 12:02:02 +00002663- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2664
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002665- the pickle module no longer accepts the deprecated None option in the
2666 args tuple returned by __reduce__().
2667
Brett Cannon84667c02004-12-07 03:25:18 +00002668- optparse now optionally imports gettext. This allows its use in setup.py.
2669
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002670- the pickle module no longer uses the deprecated bin parameter.
2671
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002672- the shelve module no longer uses the deprecated binary parameter.
2673
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002674- the pstats module no longer uses the deprecated ignore() method.
2675
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002676- the filecmp module no longer uses the deprecated use_statcache argument.
2677
Raymond Hettinger664347b2004-12-04 21:21:53 +00002678- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2679 extended or overridden by subclasses. Formerly, the subclassed method would
2680 be ignored by the rest of the module. (Bug #1078905).
2681
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002682- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002683 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002684
Walter Dörwald36733692004-12-22 12:50:50 +00002685- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2686 once when a size argument is given. This prevents a buffer overflow in the
2687 tokenizer with very long source lines.
2688
Barry Warsaw538561e2006-01-01 21:48:54 +00002689- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2690 immediately after creating the object, without any intervening
2691 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002692
Skip Montanaro05885812005-01-16 20:48:27 +00002693- The reconvert.quote function can now emit triple-quoted strings. The
2694 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002695
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002696- ``UserString.MutableString`` now supports negative indices in
2697 ``__setitem__`` and ``__delitem__``
2698
Greg Ward40407942005-03-05 02:53:17 +00002699- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2700 correctly.
2701
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002702- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2703 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2704 character even if the user has passed a size parameter to get a proper
2705 line ending. Remove the special handling of a "\r\n" that has been split
2706 between two lines.
2707
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002708- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2709 about illegal code points. The codec now supports PEP 293 style error
2710 handlers.
2711
Walter Dörwald78a78b02005-09-01 12:04:29 +00002712- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002713 from the input stream, so that the output is a byte string in the correct
2714 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002715
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002716- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2717 considering it exactly like a '*'.
2718
Walter Dörwald007f8df2005-10-09 19:42:27 +00002719- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2720 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002721
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002722- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2723
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002724- Patch #1413711: Certain patterns of differences were making difflib
2725 touch the recursion limit.
2726
Walter Dörwald58917a62006-03-31 15:26:22 +00002727- Bug #947906: An object oriented interface has been added to the calendar
2728 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002729 called as a script (e.g. via ``python -mcalendar``). Localized month and
2730 weekday names can be ouput (even if an exotic encoding is used) using
2731 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002732
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002733Build
2734-----
2735
Neal Norwitz602d3392006-03-31 08:21:40 +00002736- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2737 by using -mieee gcc option.
2738
Martin v. Löwis86d66262006-02-17 08:40:11 +00002739- Patch #1432345: Make python compile on DragonFly.
2740
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002741- Build support for Win64-AMD64 was added.
2742
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002743- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2744
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002745- Patch #881820: look for openpty and forkpty also in libbsd.
2746
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002747- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2748 The zlib module is now builtin on Windows.
2749
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002750- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2751
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002752- Bug #1189330: configure did not correctly determine the necessary
2753 value of LINKCC if python was built with GCC 4.0.
2754
Trent Mick8321b422005-07-26 02:29:21 +00002755- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2756 vulnerability in zlib 1.2.1 and 1.2.2.
2757
Brett Cannon08cd5982005-04-24 22:26:38 +00002758- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2759 flags that change binary compatibility. Changes were also made to
2760 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002761 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002762
Bob Ippolitoed233462005-03-29 13:47:59 +00002763- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2764 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2765 no longer exists). This configure patch makes things right.
2766
Martin v. Löwise2713be2005-03-08 15:03:08 +00002767- Bug #1158607: Build with --disable-unicode again.
2768
Brett Cannon46d96232005-02-16 00:07:19 +00002769- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2770 defined. Discovered as a result of not being able to build on OS X.
2771
Brett Cannon516592f2004-12-07 00:42:59 +00002772- setup.py now uses the directories specified in LDFLAGS using the -L option
2773 and in CPPFLAGS using the -I option for adding library and include
2774 directories, respectively, for compiling extension modules against. This has
2775 led to the core being compiled using the values in CPPFLAGS. It also removes
2776 the need for the special-casing of both DarwinPorts and Fink for darwin since
2777 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2778 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2779 Fink, ``-I/opt/local/include`` for DarwinPorts).
2780
Brett Cannon43802422005-02-10 20:48:03 +00002781- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2782 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2783 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2784 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002786C API
2787-----
2788
Tim Petersc9d78aa2006-03-26 23:27:58 +00002789- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2790 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2791 is obtained via the ``PyObject_`` family, it must be released via the
2792 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2793 always been officially true, but when Python's small-object allocator was
2794 introduced, an attempt was made to cater to a few extension modules
2795 discovered at the time that obtained memory via ``PyObject_New`` but
2796 released it via ``PyMem_DEL``. It's years later, and if such code still
2797 exists it will fail now (probably with segfaults, but calling wrong
2798 low-level memory management functions can yield many symptoms).
2799
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002800- Added a C API for set and frozenset objects.
2801
Raymond Hettinger66517482004-12-03 11:45:13 +00002802- Removed PyRange_New().
2803
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002804- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2805 mapping argument now. This string is used as a mapping table. Byte values
2806 greater than the length of the string and 0xFFFE are treated as undefined
2807 mappings.
