8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Neal Norwitz92422fb2006-08-18 03:57:54 +000010*Release date: XX-XXX-200X*
11
12Core and builtins
13-----------------
14
Georg Brandl5240d742007-03-13 20:46:32 +000015- Patch #1444529: the builtin compile() now accepts keyword arguments.
16
Georg Brandl7b9c5552007-03-12 14:30:05 +000017- Bug #1678647: write a newline after printing an exception in any
18 case, even when converting the value to a string failed.
19
Georg Brandl871f1bc2007-03-12 13:17:36 +000020- The dir() function has been extended to call the __dir__() method on
21 its argument, if it exists. If not, it will work like before. This allows
22 customizing the output of dir() in the presence of a __getattr__().
23
Collin Winter276887b2007-03-12 16:11:39 +000024- Patch #922167: Python no longer segfaults when faced with infinitely
25 self-recursive reload() calls (as reported by bug #742342).
26
Žiga Seilnacht89032082007-03-11 15:54:54 +000027- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
28
Collin Wintere38051d2007-03-09 20:33:07 +000029- Patch #1491866: change the complex() constructor to allow parthensized
30 forms. This means complex(repr(x)) now works instead of raising a
31 ValueError.
32
Georg Brandlaa2321b2007-03-07 00:40:28 +000033- Patch #703779: unset __file__ in __main__ after running a file. This
34 makes the filenames the warning module prints much more sensible when
35 a PYTHONSTARTUP file is used.
36
Georg Brandl49aafc92007-03-07 00:34:46 +000037- Variant of patch #697613: don't exit the interpreter on a SystemExit
38 exception if the -i command line option or PYTHONINSPECT environment
39 variable is given, but break into the interactive interpreter just like
40 on other exceptions or normal program exit.
41
Georg Brandl00cd8182007-03-06 18:41:12 +000042- Patch #1638879: don't accept strings with embedded NUL bytes in long().
43
Georg Brandl098cd692007-03-06 12:17:50 +000044- Bug #1674503: close the file opened by execfile() in an error condition.
45
Georg Brandl0fca97a2007-03-05 22:28:08 +000046- Patch #1674228: when assigning a slice (old-style), check for the
47 sq_ass_slice instead of the sq_slice slot.
48
Neal Norwitz88516a62007-02-26 22:41:45 +000049- When printing an unraisable error, don't print exceptions. before the name.
50 This duplicates the behavior whening normally printing exceptions.
51
Martin v. Löwisfd963262007-02-09 12:19:32 +000052- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
53
Brett Cannon129bd522007-01-30 21:34:36 +000054- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
55 catch a string exception raises DeprecationWarning.
56
Brett Cannonf5bee302007-01-23 23:21:22 +000057- Bug #1377858: Fix the segfaulting of the interpreter when an object created
58 a weakref on itself during a __del__ call for new-style classes (classic
59 classes still have the bug).
60
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000061- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
62 frame's thread state.
63

69 raised a warning.
70
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +000071- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
72 to avoid relying on atexit.
73
Raymond Hettinger94547f72006-12-20 06:42:06 +000074- Bug #1590891: random.randrange don't return correct value for big number
75

84
Georg Brandlb9f4ad32006-10-29 18:31:42 +000085- Bug #1576657: when setting a KeyError for a tuple key, make sure that
86 the tuple isn't used as the "exception arguments tuple".
87
Neal Norwitz21997af2006-10-28 21:19:07 +000088- Bug #1565514, SystemError not raised on too many nested blocks.
89
Thomas Hellerdf08f0b2006-10-27 18:31:36 +000090- Bug #1576174: WindowsError now displays the windows error code
91 again, no longer the posix error code.
92
Martin v. Löwisb5bc5372006-10-27 06:16:31 +000093- Patch #1549049: Support long values in structmember, issue warnings
94 if the assigned value for structmember fields gets truncated.
95
Neal Norwitzcbeb6872006-10-14 21:33:38 +000096- Update the peephole optimizer to remove more dead code (jumps after returns)
97 and inline unconditional jumps to returns.
98
Georg Brandl2c1375c2006-10-12 11:27:59 +000099- Bug #1545497: when given an explicit base, int() did ignore NULs

101
Georg Brandl846f73a2006-10-08 07:11:54 +0000102- Bug #1569998: break inside a try statement (outside a loop) is now
103 recognized and rejected.
104
Armin Rigo7ccbca92006-10-04 12:17:45 +0000105- list.pop(x) accepts any object x following the __index__ protocol.
106
107- Fix some leftovers from the conversion from int to Py_ssize_t
108 (relevant to strings and sequences of more than 2**31 items).
109
110- A number of places, including integer negation and absolute value,
111 were fixed to not rely on undefined behaviour of the C compiler
112 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000113
Georg Brandl3267d282006-09-30 09:03:42 +0000114- Bug #1566800: make sure that EnvironmentError can be called with any

116
Georg Brandl5d59c092006-09-30 08:43:30 +0000117- Patch #1567691: super() and new.instancemethod() now don't accept

130
Brett Cannon9adeab72006-09-20 18:34:28 +0000131- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
132 allows calling unicode() on exceptions classes directly to succeed.
133
Georg Brandlec6c2df2006-09-11 09:38:35 +0000134- Make _PyGILState_NoteThreadState() static, it was not used anywhere
135 outside of pystate.c and should not be necessary.
136
Georg Brandl4e933132006-09-06 20:05:58 +0000137- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
138 Also make sure that every exception class has __module__ set to
139 'exceptions'.
140
Georg Brandl98775df2006-09-06 06:09:31 +0000141- Bug #1550983: emit better error messages for erroneous relative
142 imports (if not in package and if beyond toplevel package).
143
Tim Petersc10c9d02006-09-05 02:18:09 +0000144- Overflow checking code in integer division ran afoul of new gcc
145 optimizations. Changed to be more standard-conforming.

152 head is the original string if sep was not found.
153
Neal Norwitzdac090d2006-09-05 03:53:08 +0000154- Bug #1520864: unpacking singleton tuples in list comprehensions and
155 generator expressions (x for x, in ... ) works again. Fixing this problem
156 required changing the .pyc magic number. This means that .pyc files
157 generated before 2.5c2 will be regenerated.
158
Neal Norwitzca460d92006-09-06 06:28:06 +0000159- with and as are now keywords.

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000163- Add new requirements for metaclasses. 1) If type or a subclass of type
164 occurs in __bases__, it must occur before any non-type bases, e.g.
165 before regular classes. 2) If you assign to __bases__, you may not
166 change the metaclass. Many more illegal assignments to __bases__
167 are now checked and raise TypeErrors. This changed fixed at least
168 one known crash.

Thomas Heller2456a3c2007-03-09 20:39:22 +0000234- Bug #1651235: When a tuple was passed to a ctypes function call,
235 Python would crash instead of raising an error.
236
Thomas Hellerc2f77252007-03-09 19:21:28 +0000237- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)

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

249 never made sense with ordinary subclasses -- the failure just occurred
250 later, with a more cumbersome exception.

Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000598- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
599 mode by only placing a timeout on the select() if an input hook has
600 been defined. This prevents an interactive Python from waking up 10
601 times per second. Patch by Richard Boulton.

737Core and builtins
738-----------------
739
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000740- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000741 compared equal or unequal to a string and a UnicodeDecodeError
742 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000743
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000744 Instead, the equal (==) and unequal (!=) comparison operators will
745 now issue a UnicodeWarning and interpret the two objects as
746 unequal. The UnicodeWarning can be filtered as desired using
747 the warning framework, e.g. silenced completely, turned into an
748 exception, logged, etc.
749
750 Note that compare operators other than equal and unequal will still
751 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000752
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000753- Fix segfault when doing string formatting on subclasses of long.
754
755- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
756 with new-style classes.
757
758- Fix bug related to __len__ functions returning negative values with
759 classic classes.
760
761- Patch #1538606, Fix __index__() clipping. There were some problems
762 discovered with the API and how integers that didn't fit into Py_ssize_t
763 were handled. This patch attempts to provide enough alternatives
764 to effectively use __index__.
765
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000766- Bug #1536021: __hash__ may now return long int; the final hash
767 value is obtained by invoking hash on the long int.
768
Thomas Hellerab1049c2006-08-08 17:37:00 +0000769- Bug #1536786: buffer comparison could emit a RuntimeWarning.
770
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000771- Bug #1535165: fixed a segfault in input() and raw_input() when
772 sys.stdin is closed.
773
Thomas Heller74d36f02006-08-04 18:17:40 +0000774- On Windows, the PyErr_Warn function is now exported from
775 the Python dll again.
776
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000777- Bug #1191458: tracing over for loops now produces a line event
778 on each iteration. Fixing this problem required changing the .pyc
779 magic number. This means that .pyc files generated before 2.5c1
780 will be regenerated.
781
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000782- Bug #1333982: string/number constants were inappropriately stored
783 in the byte code and co_consts even if they were not used, ie
784 immediately popped off the stack.
785
Georg Brandle9462c72006-08-04 18:03:37 +0000786- Fixed a reference-counting problem in property().

790-------
791
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000792- Fix a bug in the ``compiler`` package that caused invalid code to be
793 generated for generator expressions.
794
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000795- The distutils version has been changed to 2.5.0. The change to
796 keep it programmatically in sync with the Python version running
797 the code (introduced in 2.5b3) has been reverted. It will continue
798 to be maintained manually as static string literal.
799
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000800- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000801 and this cannot be converted to the required C type, an exception is
802 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000803 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000804
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000805- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000806 an exception.
807
Tim Petersc10c9d02006-09-05 02:18:09 +0000808- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000809 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000810 workarounds for clocks with low resolution, to stop the code yielding
811 duplicate UUIDs.
812
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000813- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
814 before raising SystemExit, allowing IDLE to honor quit() and exit().
815
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000816- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
817
Georg Brandl7a1af772006-08-14 21:55:28 +0000818- Patch #1536071: trace.py should now find the full module name of a
819 file correctly even on Windows.
820
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000821- logging's atexit hook now runs even if the rest of the module has
822 already been cleaned up.
823
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000824- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000825
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000826- Bug #1531405, format_exception no longer raises an exception if
827 str(exception) raised an exception.
828
Neil Schemenauer06ded092006-08-04 16:20:30 +0000829- Fix a bug in the ``compiler`` package that caused invalid code to be
830 generated for nested functions.

843
Thomas Heller86720042006-08-14 11:17:48 +0000844- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
845 uses the _as_parameter_ attribute when objects are passed to foreign
846 function calls. The ctypes version number was changed to 1.0.1.
847
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000848- Bug #1530559, struct.pack raises TypeError where it used to convert.
849 Passing float arguments to struct.pack when integers are expected
850 now triggers a DeprecationWarning.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000903- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000904 returned a long (see PEP 353).
905
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000906- Bug #1515471: string.replace() accepts character buffers again.
907
Neal Norwitz07aadb12006-07-30 06:55:48 +0000908- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
909 This provides the proper warning for struct.pack().
910 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
911
Neal Norwitz0d62a062006-07-30 06:53:31 +0000912- Patch #1531113: Fix augmented assignment with yield expressions.
913 Also fix a SystemError when trying to assign to yield expressions.
914
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000915- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
916 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
917 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
918 excessive filesystem operations during imports.
919
Tim Petersbc24eee2006-07-27 01:14:53 +0000920- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
921 operations on signed longs that are formally undefined by C.
922 Unfortunately, at least one compiler now cares about that, so complicated
923 the code to make that compiler happy again.
924
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000925- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
926
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000927- Patch #1232023: Stop including current directory in search
928 path on Windows.
929
Neal Norwitze1fdb322006-07-21 05:32:28 +0000930- Fix some potential crashes found with failmalloc.
931
Neal Norwitze7563102006-07-17 01:00:16 +0000932- Fix warnings reported by Klocwork's static analysis tool.
933
Neal Norwitz84be93b2006-07-16 01:50:38 +0000934- Bug #1512814, Fix incorrect lineno's when code within a function
935 had more than 255 blank lines.
936
Georg Brandl9dceedb2006-07-12 15:31:17 +0000937- Patch #1521179: Python now accepts the standard options ``--help`` and
938 ``--version`` as well as ``/?`` on Windows.
939
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000940- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000941 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000942 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000943
Tim Peters112aad32006-07-19 00:03:19 +0000944- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000945 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000946 new ``sys._current_frames()`` returns a dictionary with one entry,
947 mapping the faux "thread id" 0 to the current frame.
948
Ronald Oussoren3075e162006-07-25 20:28:55 +0000949- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000950

953-------
954
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000955- Correction of patch #1455898: In the mbcs decoder, set final=False
956 for stream decoder, but final=True for the decode function.
957
Georg Brandl07fec3a2006-08-01 18:49:24 +0000958- os.urandom no longer masks unrelated exceptions like SystemExit or
959 KeyboardInterrupt.
960
Tim Peters4643c2f2006-08-10 22:45:34 +0000961- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000962 shutil.copytree on Windows
963
Georg Brandle34ac7c2006-07-30 11:07:23 +0000964- Bug #1002398: The documentation for os.path.sameopenfile now correctly
965 refers to file descriptors, not file objects.
966
Tim Petersc10c9d02006-09-05 02:18:09 +0000967- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000968 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000969 #1513611, and probably others.
970
Georg Brandledd9b0d2006-07-29 09:33:26 +0000971- Bug #1441397: The compiler module now recognizes module and function
972 docstrings correctly as it did in Python 2.4.
973
Tim Peters6f681472006-07-27 23:44:37 +0000974- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
975 lost that tests are sorted by name before being run. This rarely
976 matters for well-written tests, but can create baffling symptoms if
977 side effects from one test to the next affect outcomes. ``DocTestFinder``
978 has been changed to sort the list of tests it returns.
979
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000980- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000981 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000982
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000983- Bug #978833: Really close underlying socket in _socketobject.close.
984
Georg Brandl8c036cc2006-08-20 13:15:39 +0000985- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
986 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000987
Georg Brandlcf0c1722006-07-26 07:23:32 +0000988- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
989 to recursive calls and call it with the failing package name.
990
Martin v. Löwis0b483032006-07-25 09:53:12 +0000991- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
992
Georg Brandlc13c34c2006-07-24 14:09:56 +0000993- Patch #1515343: Fix printing of deprecated string exceptions with a
994 value in the traceback module.
995
Greg Ward48fae7a2006-07-23 16:05:51 +0000996- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
997
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000998- Patch #1524429: Use repr() instead of backticks in Tkinter again.
999
Brett Cannoncaebe222006-07-18 04:41:36 +00001000- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1001 argument tuple. For arguments where zero is illegal, the value is forced to
1002 the minimum value that is correct. This is to support an undocumented but
1003 common way people used to fill in inconsequential information in the time
1004 tuple pre-2.4.
1005
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001006- Patch #1220874: Update the binhex module for Mach-O.
1007
Barry Warsawb110bad2006-07-21 14:51:07 +00001008- The email package has improved RFC 2231 support, specifically for
1009 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1010 (name*0=<blah>) parameter continuations. This may change the types of
1011 values returned from email.message.Message.get_param() and friends.
1012 Specifically in some cases where non-encoded continuations were used,
1013 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1014 will just return the string (since non-encoded continuations don't have
1015 charset and language parts).
1016
1017 Also, whereas % values were decoded in all parameter continuations, they are
1018 now only decoded in encoded parameter parts.
1019
Ronald Oussoren3075e162006-07-25 20:28:55 +00001020- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1021
1022- Bug #1517996: IDLE now longer shows the default Tk menu when a
1023 path browser, class browser or debugger is the frontmost window on MacOS X
1024
Barry Warsaw00decd72006-07-27 23:43:15 +00001025- Patch #1520294: Support for getset and member descriptors in types.py,
1026 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1027 of an object against these built-in types and more importantly, for getting
1028 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001031Extension Modules
1032-----------------
1033
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001034- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1035 a socket operation on a socket with a timeout, the exception will be
1036 caught correctly. Previously, the exception was not caught.
1037
Thomas Heller1393d6a2006-07-28 21:43:20 +00001038- Patch #1529514: The _ctypes extension is now compiled on more
1039 openbsd target platforms.
1040
Tim Peters9cab5932006-07-28 00:30:00 +00001041- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1042 a memory leak, affecting pickles and deep copies.
1043
Tim Petersbc24eee2006-07-27 01:14:53 +00001044- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001045 Paul Eggert.
1046
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001047- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1048
Thomas Hellerce049a02006-07-14 17:51:14 +00001049- Patch #1521817: Index range checking on ctypes arrays containing
1050 exactly one element enabled again. This allows iterating over these
1051 arrays, without the need to check the array size before.
1052
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001053- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001054 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001055 /dev/null in certain cases; this is now fixed.
1056
Thomas Heller47d7a062006-07-12 08:43:47 +00001057- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1058 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001059
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001060- Because of a misspelled preprocessor symbol, ctypes was always
1061 compiled without thread support; this is now fixed.
1062
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001063- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1064 methods now allow their database parameter to be None as the
1065 sleepycat API allows.
1066
Matt Flemingec926502006-07-28 11:27:27 +00001067- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1068 bluetooth API compared with Linux and FreeBSD.
1069
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001070Tests
1071-----
1072
1073- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1074 how long the test file should take to play. Now accepts taking 2.93 secs
1075 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1076
Georg Brandl4793aa32006-07-28 18:31:39 +00001077- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1078 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1079 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001086Mac
1087---
1088
1089- PythonLauncher now works correctly when the path to the script contains
1090 characters that are treated specially by the shell (such as quotes).
1091
1092- Bug #1527397: PythonLauncher now launches scripts with the working directory
1093 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001094 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001095 expect.

1104-----------------
1105
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001106- Bug #1441486: The literal representation of -(sys.maxint - 1)
1107 again evaluates to a int object, not a long.
1108
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001109- Bug #1501934: The scope of global variables that are locally assigned
1110 using augmented assignment is now correctly determined.
1111
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001112- Bug #927248: Recursive method-wrapper objects can now safely
1113 be released.
1114
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001115- Bug #1417699: Reject locale-specific decimal point in float()
1116 and atof().
1117
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001118- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1119 omit a default "error" argument for NULL pointer. This allows
1120 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001121
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001122- Bug #1519018: 'as' is now validated properly in import statements.
1123
Neal Norwitz28746ab2006-07-09 22:14:42 +00001124- On 64 bit systems, int literals that use less than 64 bits are
1125 now ints rather than longs.
1126
Neal Norwitzed657552006-07-10 00:04:44 +00001127- Bug #1512814, Fix incorrect lineno's when code at module scope
1128 started after line 256.
1129
Tim Peters32a83612006-07-10 21:08:24 +00001130- New function ``sys._current_frames()`` returns a dict mapping thread
1131 id to topmost thread stack frame. This is for expert use, and is
1132 especially useful for debugging application deadlocks. The functionality
1133 was previously available in Fazal Majid's ``threadframe`` extension
1134 module, but it wasn't possible to do this in a wholly threadsafe way from
1135 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001140- Bug #1257728: Mention Cygwin in distutils error message about a missing
1141 VS 2003.
1142
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001143- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1144
Tim Peters32a83612006-07-10 21:08:24 +00001145- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001146 environment variable to be set in order to the SDK environment
1147 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001151- warnings.py now ignores ImportWarning by default
1152
Thomas Woutersadd19112006-07-05 11:03:49 +00001153- string.Template() now correctly handles tuple-values. Previously,
1154 multi-value tuples would raise an exception and single-value tuples would
1155 be treated as the value they contain, instead.
1156
Martin v. Löwisede77f52006-07-03 13:01:35 +00001157- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1158 even if some data are received.
1159
Martin v. Löwis45482392006-07-03 12:28:58 +00001160- Bug #1267547: Put proper recursive setup.py call into the
1161 spec file generated by bdist_rpm.
1162
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001163- Bug #1514693: Update turtle's heading when switching between
1164 degrees and radians.
1165
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001166- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001167 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001168
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001169- Bug #1514703: Only setup canvas window in turtle when the canvas
1170 is created.
1171
Martin v. Löwis7596e832006-07-01 15:33:37 +00001172- Bug #1513223: .close() of a _socketobj now releases the underlying
1173 socket again, which then gets closed as it becomes unreferenced.
1174
Fred Drake10497c82006-06-29 02:57:48 +00001175- Bug #1504333: Make sgmllib support angle brackets in quoted
1176 attribute values.
1177
1178- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1179 sgmllib ('[' and ']' were not accepted).
1180
Georg Brandl1be63af2006-06-28 20:23:25 +00001181- Fix a bug in the turtle module's end_fill function.
1182
Brett Cannon53ab5b72006-06-22 16:49:14 +00001183- Bug #1510580: The 'warnings' module improperly required that a Warning
1184 category be either a types.ClassType and a subclass of Warning. The proper
1185 check is just that it is a subclass with Warning as the documentation states.
1186
Georg Brandlad29e632006-06-21 17:45:17 +00001187- The compiler module now correctly compiles the new try-except-finally
1188 statement (bug #1509132).
1189
Neal Norwitz60373cd2006-06-22 06:30:50 +00001190- The wsgiref package is now installed properly on Unix.
1191
Vinay Sajip28e57612006-07-01 10:45:20 +00001192- A bug was fixed in logging.config.fileConfig() which caused a crash on
1193 shutdown when fileConfig() was called multiple times.
1194
Gerhard Häring762fbd32006-07-02 17:48:30 +00001195- The sqlite3 module did cut off data from the SQLite database at the first
1196 null character before sending it to a custom converter. This has been fixed
1197 now.
1198
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001199Extension Modules
1200-----------------
1201
Tim Peters112aad32006-07-19 00:03:19 +00001202- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1203 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1204 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001205
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001206- Assigning None to pointer type fields in ctypes structures possible
1207 overwrote the wrong fields, this is fixed now.
1208
1209- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1210 on non-Windows platforms.
1211
1212- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1213 integer or long, without range checking.
1214
1215- Patch #1517790: It is now possible to use custom objects in the ctypes
1216 foreign function argtypes sequence as long as they provide a from_param
1217 method, no longer is it required that the object is a ctypes type.
1218
1219- The '_ctypes' extension module now works when Python is configured
1220 with the --without-threads option.
1221
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001222- Bug #1513646: os.access on Windows now correctly determines write
1223 access, again.
1224
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001225- Bug #1512695: cPickle.loads could crash if it was interrupted with
1226 a KeyboardInterrupt.
1227
Neal Norwitza12aa882006-07-06 06:45:08 +00001228- Bug #1296433: parsing XML with a non-default encoding and
1229 a CharacterDataHandler could crash the interpreter in pyexpat.
1230
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001231- Patch #1516912: improve Modules support for OpenVMS.

1237
Tim Peters32a83612006-07-10 21:08:24 +00001238- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001239 Previously, the slight difference could cause compilation errors of the
1240 'zlib' module on systems with more than one version of zlib.
1241
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001242- The MSI compileall step was fixed to also support a TARGETDIR

1273Core and builtins
1274-----------------
1275
Georg Brandla56b9152006-06-19 06:35:54 +00001276- Patch #1507676: Error messages returned by invalid abstract object operations
1277 (such as iterating over an integer) have been improved and now include the
1278 type of the offending object to help with debugging.
1279
Brett Cannonea3912b2006-06-13 21:46:41 +00001280- Bug #992017: A classic class that defined a __coerce__() method that returned
1281 its arguments swapped would infinitely recurse and segfault the interpreter.
1282
Neal Norwitz909eb122006-06-12 02:13:21 +00001283- Fix the socket tests so they can be run concurrently.
1284
Neal Norwitzb9845e72006-06-12 02:11:18 +00001285- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001286 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001287
Brett Cannon22565aa2006-06-09 22:31:23 +00001288- Bug #532646: object.__call__() will continue looking for the __call__
1289 attribute on objects until one without one is found. This leads to recursion
1290 when you take a class and set its __call__ attribute to an instance of the
1291 class. Originally fixed for classic classes, but this fix is for new-style.
1292 Removes the infinite_rec_3 crasher.
1293
Georg Brandl24250812006-06-09 18:45:48 +00001294- The string and unicode methods startswith() and endswith() now accept
1295 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1296
Brett Cannonde3b0522006-06-08 17:00:45 +00001297- Buffer objects, at the C level, never used the char buffer
1298 implementation even when the char buffer for the wrapped object was
1299 explicitly requested (originally returned the read or write buffer).
1300 Now a TypeError is raised if the char buffer is not present but is
1301 requested.
1302
Georg Brandlddbaa662006-06-04 21:56:52 +00001303- Patch #1346214: Statements like "if 0: suite" are now again optimized
1304 away like they were in Python 2.4.
1305
Georg Brandlb7c8f542006-05-27 12:30:25 +00001306- Builtin exceptions are now full-blown new-style classes instead of
1307 instances pretending to be classes, which speeds up exception handling
1308 by about 80% in comparison to 2.5a2.
1309
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001310- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1311 Unicode 4.1.
1312
Georg Brandlf4ef1162006-05-26 18:03:31 +00001313- Patch #921466: sys.path_importer_cache is now used to cache valid and
1314 invalid file paths for the built-in import machinery which leads to
1315 fewer open calls on startup.
1316
Tim Peters696cf432006-05-24 21:10:40 +00001317- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1318 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1319 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1320 the number of input digits (it was and remains linear-time for bases
1321 2, 4, 8, 16 and 32).
1322
Tim Petersb713ec22006-05-23 18:45:30 +00001323- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1324 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1325 an integer close to ``sys.maxint``. This was repaired by patch
1326 #1335972, which also gives a nice speedup.
1327
Richard Jonescebbefc2006-05-23 18:28:17 +00001328- Patch #1337051: reduced size of frame objects.
1329
1330- PyErr_NewException now accepts a tuple of base classes as its
1331 "base" parameter.
1332
Richard Jones7c88dcc2006-05-23 10:37:38 +00001333- Patch #876206: function call speedup by retaining allocated frame
1334 objects.
1335
Georg Brandl7b90e162006-05-18 07:01:27 +00001336- Bug #1462152: file() now checks more thoroughly for invalid mode
1337 strings and removes a possible "U" before passing the mode to the
1338 C library function.
1339
Neal Norwitz1004a532006-05-15 07:17:23 +00001340- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1341
Neal Norwitz373f0a72006-05-15 07:04:36 +00001342- Bug #1487966: Fix SystemError with conditional expression in assignment
1343
Martin v. Löwis879768d2006-05-11 13:28:43 +00001344- WindowsError now has two error code attributes: errno, which carries
1345 the error values from errno.h, and winerror, which carries the error
1346 values from winerror.h. Previous versions put the winerror.h values
1347 (from GetLastError()) into the errno attribute.
1348
Martin v. Löwis77736712006-05-04 05:51:03 +00001349- Patch #1475845: Raise IndentationError for unexpected indent.
1350
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001351- Patch #1479181: split open() and file() from being aliases for each other.
1352
Tim Peters44bd9862006-06-01 13:49:23 +00001353- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1354 methods were always silently ignored by dictionaries when comparing keys.
1355 They are now passed through (except when using the C API function
1356 ``PyDict_GetItem()``, whose semantics did not change).
1357
1358- Bug #1456209: In some obscure cases it was possible for a class with a
1359 custom ``__eq__()`` method to confuse dict internals when class instances
1360 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1361 No, you don't have any code that did this ;-)

1368- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1369
Brett Cannon6ee7d012006-06-08 16:23:04 +00001370- Change binascii.hexlify to accept a read-only buffer instead of only a char
1371 buffer and actually follow its documentation.
1372
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001373- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1374
Nick Coghlanc649ec52006-05-29 12:43:05 +00001375- Patch #1478788 (modified version): The functional extension module has
1376 been renamed to _functools and a functools Python wrapper module added.
1377 This provides a home for additional function related utilities that are
1378 not specifically about functional programming. See PEP 309.
1379
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001380- Patch #1493701: performance enhancements for struct module.

1383
Georg Brandl8d3342b2006-05-16 07:38:27 +00001384- Patch #1435422: zlib's compress and decompress objects now have a
1385 copy() method.
1386
Andrew MacIntyre92913322006-06-13 15:04:24 +00001387- Patch #1454481: thread stack size is now tunable at runtime for thread
1388 enabled builds on Windows and systems with Posix threads support.
1389
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001390- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1391 (up to the system limit of 32K characters).
1392
1393- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1394 As a result, these functions now raise WindowsError instead of OSError.
1395
Tim Peters7a822da2006-05-25 21:50:17 +00001396- ``time.clock()`` on Win64 should use the high-performance Windows
1397 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1398 Windows platforms).
1399
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001400- Calling Tk_Init twice is refused if the first call failed as that
1401 may deadlock.
1402
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001403- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1404 accept it without potentially using an uninitialized pointer.
1405
1406- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1407 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1408 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +00001410- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001411 [pybsddb project SF patch number 1466734]
1412
Gregory P. Smith372b5832006-06-05 18:48:21 +00001413- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1414 parameter is supplied. [SF pybsddb bug #1477863]
1415
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001416- bsddb: the __len__ method of a DB object has been fixed to return correct
1417 results. It could previously incorrectly return 0 in some cases.
1418 Fixes SF bug 1493322 (pybsddb bug 1184012).
1419
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001420- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1421 aborts the db transaction safely when a modifier callback fails.
1422 Fixes SF python patch/bug #1408584.
1423
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001424- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001425 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001426 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1427 database calls that would previously deadlock. [SF python bug #775414]
1428
Vinay Sajip28e57612006-07-01 10:45:20 +00001429- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1444
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001445- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1446
Martin v. Löwis337487e2006-06-17 09:15:14 +00001447- Patch #763580: Add name and value arguments to Tkinter variable

Georg Brandl83cc0d02006-06-14 08:50:03 +00001450- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1451 mime.types file for determining MIME types.
1452
Georg Brandl2605ca82006-06-14 06:08:31 +00001453- Bug #1339007: Shelf objects now don't raise an exception in their

1455
Martin v. Löwisd8251432006-06-14 05:21:04 +00001456- Patch #1455898: The MBCS codec now supports the incremental mode for
1457 double-byte encodings.
1458
Tim Peters43898b42006-06-14 04:09:25 +00001459- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1460 guarantee that adjacent triples in the return list always describe
1461 non-adjacent blocks. Previously, a pair of matching blocks could end
1462 up being described by multiple adjacent triples that formed a partition
1463 of the matching pair.
1464
Greg Ward0e0c9f42006-06-11 16:24:11 +00001465- Bug #1498146: fix optparse to handle Unicode strings in option help,

1471 clarify docs.
1472
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001473- The wsgiref package has been added to the standard library.
1474
Nick Coghlan676725d2006-06-08 13:54:49 +00001475- The functions update_wrapper() and wraps() have been added to the functools
1476 module. These make it easier to copy relevant metadata from the original
1477 function when writing wrapper functions.
1478
Tim Petersd6a9eef2006-06-05 01:48:21 +00001479- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1480 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001481
Martin v. Löwis3f767792006-06-04 19:36:28 +00001482- Patch #1359618: Speed up charmap encoder by using a trie structure
1483 for lookup.
1484
Tim Petersd609b1a2006-06-02 23:22:51 +00001485- The functions in the ``pprint`` module now sort dictionaries by key
1486 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1487 if and only if its display required more than one line, although that
1488 wasn't documented. The new behavior increases predictability; e.g.,
1489 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1490
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001491- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1492 (thanks for J. J. Lee).
1493
Georg Brandl2b330372006-05-28 20:23:12 +00001494- Patch #1496206: improve urllib2 handling of passwords with respect to
1495 default HTTP and HTTPS ports.
1496
George Yoshidaf3c65de2006-05-28 16:39:09 +00001497- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1498
Bob Ippolito7298f272006-05-23 18:43:47 +00001499- Patch #1281707: speed up gzip.readline.
1500
Georg Brandlb89316f2006-05-17 15:51:16 +00001501- Patch #1180296: Two new functions were added to the locale module:
1502 format_string() to get the effect of "format % items" but locale-aware,
1503 and currency() to format a monetary number with currency sign.
1504
Georg Brandle3a25832006-05-17 14:56:04 +00001505- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1506 and several features added, such as speed and geometry control.
1507
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001508- Patch #1488881: add support for external file objects in bz2 compressed
1509 tarfiles.
1510
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001511- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1512 stdout arguments, making it possible to redirect input and output
1513 for remote debugging.
1514
1515- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1516 a couple of issues, notably handling of long file names using the
1517 GNU LONGNAME extension.
1518
1519- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1520 new flag when ``name`` is already the name of an option flag.
1521
1522- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1523 package.
1524
1525- Patch #1472854: make the rlcompleter.Completer class usable on non-
1526 UNIX platforms.
1527
1528- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1529
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001530- Bug #1472827: correctly escape newlines and tabs in attribute values in
1531 the saxutils.XMLGenerator class.

Neal Norwitz58e28882006-05-19 07:00:58 +00001543- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
1544
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001545- Patch #1471883: Add --enable-universalsdk.

1560
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001561What's New in Python 2.5 alpha 2?
1562=================================
1563
1564*Release date: 27-APR-2006*
1565
1566Core and builtins
1567-----------------
1568
Thomas Heller1b046642006-04-18 18:51:06 +00001569- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1570 by converting these apis from macros into exported functions again:
1571
1572 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1573 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1574 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1575 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1576 PyRun_String Py_CompileString
1577
Martin v. Löwis45294a92006-04-18 06:24:08 +00001578- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1579
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001580- All uses of PyStructSequence_InitType have been changed to initialize
1581 the type objects only once, even if the interpreter is initialized
1582 multiple times.
1583
Neal Norwitz61546162006-04-14 05:20:28 +00001584- Bug #1454485, array.array('u') could crash the interpreter. This was
1585 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1586 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1587
1588- Py_UNICODE is unsigned. It was always documented as unsigned, but
1589 due to a bug had a signed value in previous versions.
1590
Tim Peters3a5e8b12006-04-11 01:44:07 +00001591- Patch #837242: ``id()`` of any Python object always gives a positive
1592 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1593 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001594 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001595 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001596
Tim Peters3a5e8b12006-04-11 01:44:07 +00001597 def __hash__(self):
1598 return id(self) # WRONG
1599
1600 because a hash result must be a (short) Python int but it was always
1601 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001602 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001603 was always usable as a hash value before this patch. That's no longer
1604 necessarily so.
1605
1606- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001607 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001608 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001609 #1454844)
1610
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001611- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1612 involving generators that have paused outside of any ``try`` or ``with``
1613 blocks. (In 2.5a1, a paused generator that was part of a reference
1614 cycle could not be garbage collected, regardless of whether it was
1615 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001616
Anthony Baxter51bcb682006-04-05 14:51:42 +00001617Extension Modules

1619
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001620- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1621 is a macro.
1622
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001623- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1624 fails with an error condition.
1625
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001626- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1627
1628- Bug #1117761: bsddb.*open() no longer raises an exception when using
1629 the cachesize parameter.
1630
1631- Bug #1149413: bsddb.*open() no longer raises an exception when using
1632 a temporary db (file=None) with the 'n' flag to truncate on open.
1633
1634- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1635 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001636
Armin Rigoa9017c32006-04-19 11:50:27 +00001637- Patch #1062014: AF_UNIX sockets under Linux have a special
1638 abstract namespace that is now fully supported.
1639

1641-------
1642
Peter Astrand7d1d4362006-07-14 14:04:45 +00001643- Bug #1223937: subprocess.CalledProcessError reports the exit status
1644 of the process using the returncode attribute, instead of
1645 abusing errno.
1646
Tim Peters711bf302006-04-25 03:31:36 +00001647- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1648 a doctest to be skipped (the code is not run, and the expected output
1649 or exception is ignored).
1650
Nick Coghlanda2268f2006-04-24 04:37:15 +00001651- Fixed contextlib.nested to cope with exceptions being raised and
1652 caught inside exit handlers.
1653
Greg Wardab05edc2006-04-23 03:47:58 +00001654- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1655 hex, octal, or binary; add ``append_const`` action; keep going if
1656 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1657 added ``epilog`` for better help generation).
1658
Tim Peters21fbd572006-04-21 21:18:10 +00001659- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1660 called from a thread spawned as a side effect of importing a module.
1661
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001662- The pydoc module now supports documenting packages contained in
1663 .zip or .egg files.
1664
1665- The pkgutil module now has several new utility functions, such
1666 as ``walk_packages()`` to support working with packages that are either
1667 in the filesystem or zip files.
1668
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001669- The mailbox module can now modify and delete messages from
1670 mailboxes, in addition to simply reading them. Thanks to Gregory
1671 K. Johnson for writing the code, and to the 2005 Google Summer of
1672 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001673
Tim Petersc7605f22006-04-17 21:12:33 +00001674- The ``__del__`` method of class ``local`` in module ``_threading_local``
1675 returned before accomplishing any of its intended cleanup.
1676
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001677- Patch #790710: Add breakpoint command lists in pdb.

1682
Anthony Baxtere29002c2006-04-12 12:07:31 +00001683- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1684 Windows. Bug #1469163.
1685
Phillip J. Eby47032112006-04-11 01:07:43 +00001686- The warnings, linecache, inspect, traceback, site, and doctest modules
1687 were updated to work correctly with modules imported from zipfiles or
1688 via other PEP 302 __loader__ objects.
1689
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001690- Patch #1467770: Reduce usage of subprocess._active to processes which
1691 the application hasn't waited on.

1698 direct output to an alternate file-like object.
1699

1701-----
1702
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001703- The Makefile now has a reindent target, which runs reindent.py on
1704 the library.
1705
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001706- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001710- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1711 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001712 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001713 CXX from --with-cxx-main, see description in README.
1714
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001715- Patch #1429775: Link extension modules with the shared libpython.
1716
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001717- Fixed a libffi build problem on MIPS systems.
1718
Tim Peters8931ff12006-05-13 23:28:20 +00001719- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1720 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1721 and "%zu" for unsigned integers of type ``size_t``.
1722
Anthony Baxter51bcb682006-04-05 14:51:42 +00001723Tests
1724-----
1725
Nick Coghlanda2268f2006-04-24 04:37:15 +00001726- test_contextlib now checks contextlib.nested can cope with exceptions
1727 being raised and caught inside exit handlers.
1728
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001729- test_cmd_line now checks operation of the -m and -c command switches
1730
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001731- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1732 it separately and by hand. It also wasn't cleaning up its changes to
1733 the current Decimal context.
1734
Thomas Woutersabd08882006-04-26 15:53:30 +00001735- regrtest.py now has a -M option to run tests that test the new limits of
1736 containers, on 64-bit architectures. Running these tests is only sensible
1737 on 64-bit machines with more than two gigabytes of memory. The argument
1738 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001749- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1750
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001751- PEP 343: Added Context Types section to the library reference
1752 and attempted to bring other PEP 343 related documentation into
1753 line with the implementation and/or python-dev discussions.
1754
Tim Peters8dc73d22006-04-24 02:03:16 +00001755- Bug #1337990: clarified that ``doctest`` does not support examples
1756 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001759What's New in Python 2.5 alpha 1?
1760=================================
1761
Anthony Baxterebed3f62006-04-03 15:03:44 +00001762*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001763
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001764Core and builtins
1765-----------------
1766
Nick Coghlan43832302006-04-23 17:04:07 +00001767- PEP 338: -m command line switch now delegates to runpy.run_module
1768 allowing it to support modules in packages and zipfiles
1769
Martin v. Löwisc661b882006-04-20 04:54:23 +00001770- On Windows, .DLL is not an accepted file name extension for
1771 extension modules anymore; extensions are only found if they
1772 end in .PYD.
1773
Martin v. Löwisea62d252006-04-03 10:56:49 +00001774- Bug #1421664: sys.stderr.encoding is now set to the same value as
1775 sys.stdout.encoding.
1776
Neal Norwitz92e212f2006-04-03 04:48:37 +00001777- __import__ accepts keyword arguments.
1778

1780
Anthony Baxter262c00a2006-03-30 10:53:17 +00001781- Fixed bug #1459029 - unicode reprs were double-escaped.
1782
Hye-Shik Changd478f342006-03-23 12:32:36 +00001783- Patch #1396919: The system scope threads are reenabled on FreeBSD
1784 5.4 and later versions.
1785
Neal Norwitze98ccf62006-03-23 05:39:47 +00001786- Bug #1115379: Compiling a Unicode string with an encoding declaration
1787 now gives a SyntaxError.
1788
Georg Brandlabd1ff82006-03-18 07:59:59 +00001789- Previously, Python code had no easy way to access the contents of a
1790 cell object. Now, a ``cell_contents`` attribute has been added
1791 (closes patch #1170323).
1792
Tim Peterscf79aac2006-03-16 01:14:46 +00001793- Patch #1123430: Python's small-object allocator now returns an arena to
1794 the system ``free()`` when all memory within an arena becomes unused
1795 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1796 freed. Some applications will see a drop in virtual memory size now,
1797 especially long-running applications that, from time to time, temporarily
1798 use a large number of small objects. Note that when Python returns an
1799 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001800 platform C library will in turn return that memory to the operating system.
1801 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001802 appears to be effective at least on Microsoft C and gcc-based systems.
1803 Thanks to Evan Jones for hard work and patience.
1804
Georg Brandl533ff6f2006-03-08 18:09:27 +00001805- Patch #1434038: property() now uses the getter's docstring if there is
1806 no "doc" argument given. This makes it possible to legitimately use
1807 property() as a decorator to produce a read-only property.
1808
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001809- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1810 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1811 of requiring an int or long in slicing and a few other contexts, enabling
1812 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1813
Neal Norwitz995acdf2006-03-07 05:01:00 +00001814- Fixed various bugs reported by Coverity's Prevent tool.
1815
Brett Cannonbf364092006-03-01 04:25:17 +00001816- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1817 new exception base class, BaseException, which has a new message attribute.
1818 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1819 Raising a string exception now raises a DeprecationWarning.
1820
Thomas Woutersfb609f42006-02-28 16:37:25 +00001821- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1822 explicitly relative, using 'from .module import name' to mean 'from the same
1823 package as this module is in. Imports without dots still default to the
1824 old relative-then-absolute, unless 'from __future__ import
1825 absolute_import' is used.
1826
Brett Cannona7446e32006-02-27 23:39:10 +00001827- Properly check if 'warnings' raises an exception (usually when a filter set
1828 to "error" is triggered) when raising a warning for raising string
1829 exceptions.
1830
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001831- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001832 The name was removed from Include/code.h.
1833
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001834- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001835
Guido van Rossum1968ad32006-02-25 22:38:04 +00001836- Patch 1433928:
1837 - The copy module now "copies" function objects (as atomic objects).
1838 - dict.__getitem__ now looks for a __missing__ hook before raising
1839 KeyError.
1840
Tim Peters84ef21c2006-02-28 20:39:06 +00001841- PEP 343: with statement implemented. Needs ``from __future__ import
1842 with_statement``. Use of 'with' as a variable will generate a warning.
1843 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001844 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001845 The following objects have __context__ methods:
1846 - The built-in file type.
1847 - The thread.LockType type.
1848 - The following types defined by the threading module:
1849 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1850 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001851
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001852- Fix the encodings package codec search function to only search
1853 inside its own package. Fixes problem reported in patch #1433198.
1854
1855 Note: Codec packages should implement and register their own
1856 codec search function. PEP 100 has the details.
1857
Tim Peters9ea89d22006-06-04 03:26:02 +00001858- PEP 353: Using ``Py_ssize_t`` as the index type.
1859
1860- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1861 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1862 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1863 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1864 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001865
Neal Norwitzfc76d632006-01-10 06:03:13 +00001866- Patch #1400181, fix unicode string formatting to not use the locale.
1867 This is how string objects work. u'%f' could use , instead of .
1868 for the decimal point. Now both strings and unicode always use periods.
1869
Neal Norwitz671b9e32006-01-09 07:07:12 +00001870- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1871 configure would break checking curses.h.
1872
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001873- Bug #959576: The pwd module is now builtin. This allows Python to be
1874 built on UNIX platforms without $HOME set.
1875
Neal Norwitzc10978f2005-12-19 06:07:16 +00001876- Bug #1072182, fix some potential problems if characters are signed.
1877
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001878- Bug #889500, fix line number on SyntaxWarning for global declarations.
1879
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001880- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1881
Neal Norwitze7214a12005-12-18 05:03:17 +00001882- Support for converting hex strings to floats no longer works.
1883 This was not portable. float('0x3') now raises a ValueError.
1884
Barry Warsaw2a38a862005-12-18 01:27:35 +00001885- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001886 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001887 is now displayed in interactive prompt banner.
1888
Georg Brandlfa166682005-12-17 21:45:17 +00001889- Implementation of PEP 341 - Unification of try/except and try/finally.
1890 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001891 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001892
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001893- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1894 now encodes backslash correctly.
1895
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001896- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1897
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001898- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001899 and long longs.
1900
Neal Norwitz67715f02005-11-09 06:59:35 +00001901- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001902 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001903 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001904
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001905- Replaced most Unicode charmap codecs with new ones using the
1906 new Unicode translate string feature in the builtin charmap
1907 codec; the codecs were created from the mapping tables available
1908 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1909 encodings now include a mapping for the Apple logo)
1910
Tim Peterse3547fd2005-12-16 23:13:57 +00001911- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001912
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001913- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001914
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001915- A new AST parser implementation was completed. The abstract
1916 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001917 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001918
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001919- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001920 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1921
Neal Norwitz708e51a2005-10-03 04:48:15 +00001922- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1923
Neal Norwitz11bd1192005-10-03 00:54:56 +00001924- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1925 Provide a warning when a directory is passed on the command line.
1926
Neal Norwitz40d37812005-10-02 01:48:49 +00001927- Fix segfault with invalid coding.
1928
1929- SF bug #772896: unknown encoding results in MemoryError.
1930
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001931- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001932 supported a __len__() method which evaluated to False when the iterator
1933 was empty.
1934
Guido van Rossum630db602005-09-20 18:49:54 +00001935- On 64-bit platforms, when __len__() returns a value that cannot be
1936 represented as a C int, raise OverflowError.
1937
Skip Montanarof8948ca2005-09-19 03:54:46 +00001938- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001939 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001940
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001941- SF bug #893549: parsing keyword arguments was broken with a few format
1942 codes.
1943
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001944- Changes donated by Elemental Security to make it work on AIX 5.3
1945 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1946 bug #105470: test_pwd fails on 64bit system (Opteron).
1947
Guido van Rossum539c6622005-09-14 17:49:54 +00001948- Changes donated by Elemental Security to make it work on HP-UX 11 on
1949 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1950
Georg Brandl4550b8d2005-08-26 06:43:52 +00001951- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001952 (fixes bug #1119418).
1953
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001954- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1955
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001956- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1957 exceptions that cause a function to exit.
1958
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001959- The implementation of set() and frozenset() was revised to use its
1960 own internal data structure. Memory consumption is reduced by 1/3
1961 and there are modest speed-ups as well. The API is unchanged.
1962
Tim Petersde7990b2005-07-17 23:45:23 +00001963- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1964
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001965- SF bug #1229429: PyObject_CallMethod failed to decrement some
1966 reference counts in some error exit cases.
1967
Tim Petersecc6e6a2005-07-10 22:30:55 +00001968- SF bug #1185883: Python's small-object memory allocator took over
1969 a block managed by the platform C library whenever a realloc specified
1970 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001971 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001972 portable way to copy data from the C-managed block into Python's
1973 small-object space without risking a memory fault. Python's small-object
1974 realloc now leaves such blocks under the control of the platform C
1975 realloc.
1976
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001977- SF bug #1232517: An overflow error was not detected properly when
1978 attempting to convert a large float to an int in os.utime().
1979
Raymond Hettinger3296e692005-06-29 23:29:56 +00001980- SF bug #1224347: hex longs now print with lowercase letters just
1981 like their int counterparts.
1982
Michael W. Hudson188d4362005-06-20 16:52:57 +00001983- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1984 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1985 interpreter states; back out that fix and do a better job (see
1986 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1987 for a longer write-up of the problem).
1988
Michael W. Hudsondf888462005-06-03 14:41:55 +00001989- SF patch #1180995: marshal now uses a binary format by default when
1990 serializing floats.
1991
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001992- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1993 the routines that promise to produce IEEE 754 binary representations
1994 of floats now simply copy bytes around.
1995
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001996- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1997 278.
1998
Brett Cannonc3647ac2005-04-26 03:45:26 +00001999- patch #1109424: int, long, float, complex, and unicode now check for the
2000 proper magic slot for type conversions when subclassed. Previously the
2001 magic slot was ignored during conversion. Semantics now match the way
2002 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002003 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002004 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002005 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002006
Barry Warsawc8d907c2005-04-19 23:43:40 +00002007- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2008 NULL, now raise an AttributeError when attempting to set or delete the
2009 attribute. Previously a TypeError was raised, but this was inconsistent
2010 with the equivalent pure-Python implementation.
2011
Michael W. Hudson774479c2005-04-18 08:46:17 +00002012- It is now safe to call PyGILState_Release() before
2013 PyEval_InitThreads() (note that if there is reason to believe there
2014 are multiple threads around you still must call PyEval_InitThreads()
2015 before using the Python API; this fix is for extension modules that
2016 have no way of knowing if Python is multi-threaded yet).
2017
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002018- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2019 disabled caused a crash.
2020
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002021- Bug #1165306: instancemethod_new allowed the creation of a method
2022 with im_class == im_self == NULL, which caused a crash when called.
2023
Tim Petersecc6e6a2005-07-10 22:30:55 +00002024- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002025 fixes the crash seen in bug #1165761
2026
Raymond Hettinger96229b12005-03-11 06:49:40 +00002027- Added two new builtins, any() and all().
2028
Brett Cannon409d8f22005-03-05 06:47:57 +00002029- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002030 (e.g., ``class C(): pass`` is no longer a syntax error).
2031 Patch #1176012 added support to the 'parser' module and 'compiler' package
2032 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002033
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002034- Patch #1115086: Support PY_LONGLONG in structmember.
2035
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002036- Bug #1155938: new style classes did not check that __init__() was
2037 returning None.
2038
Tim Petersecc6e6a2005-07-10 22:30:55 +00002039- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002040 ('\') with a specific error message.
2041
Martin v. Löwisff232d72005-03-03 09:24:38 +00002042- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2043
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002044- Bug #1124295: the __name__ attribute of file objects was
2045 inadvertently made inaccessible in restricted mode.
2046
Tim Petersecc6e6a2005-07-10 22:30:55 +00002047- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002048 an ferror() call.
2049

Neil Schemenauercf52c072005-08-12 17:34:58 +00002065- Change the %s format specifier for str objects so that it returns a
2066 unicode instance if the argument is not an instance of basestring and
2067 calling __str__ on the argument returns a unicode instance.
2068
Tim Petersf4e69282006-02-27 17:15:31 +00002069- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2070 current thread state when the auto-GIL-state machinery knows about
2071 it (since the thread state is being deleted, continuing to remember it
2072 can't help, but can hurt if another thread happens to get created with
2073 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002265- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2266 been renamed to have only a single underscore prefix. This was done to
2267 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002268
Nick Coghlan43832302006-04-23 17:04:07 +00002269- PEP 338: new module runpy defines a run_module function to support
2270 executing modules which provide access to source code or a code object
2271 via the PEP 302 import mechanisms.
2272
Anthony Baxter93f5b932006-04-03 08:05:07 +00002273- The email module's parsedate_tz function now sets the daylight savings

2281 in attribute values.
2282
Anthony Baxterc51ee692006-04-01 00:57:31 +00002283- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002284 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002285 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002286 module will not be built.
2287
Tim Petersc17976e2006-04-01 00:26:53 +00002288- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2289 aren't officially supported here, and trying to use them will probably
2290 raise an exception some day. But dicts have been allowed, and "mostly
2291 worked", so support for them won't go away without warning.
2292
Georg Brandl338ef7d2006-03-31 18:42:16 +00002293- Bug #1445068: getpass.getpass() can now be given an explicit stream
2294 argument to specify where to write the prompt.
2295

2311
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002312- email 4.0 package now integrated. This is largely the same as the email 3.0
2313 package that was included in Python 2.3, except that PEP 8 module names are
2314 now used (e.g. mail.message instead of email.Message). The MIME classes
2315 have been moved to a subpackage (e.g. email.mime.text instead of
2316 email.MIMEText). The old names are still supported for now. Several
2317 deprecated Message methods have been removed and lots of bugs have been

2321 (a subclass of tuple) that provides incremental decoders and encoders
2322 (a way to use stateful codecs without the stream API). Python functions
2323 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well

2408
2409 "The consensus of researchers in this area (at least as
2410 expressed at the NIST Hash Function Workshop 10/31/05),
2411 is that SHA-256 is a good choice for the time being, but
2412 that research should continue, and other alternatives may
2413 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002579 flags on the HTTP listening socket.
2580
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002581- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2582 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2583
Fred Drakefbdeaad2006-07-29 16:56:15 +00002584- Patches #893642, #1039083: add allow_none, encoding arguments to
2585 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002586
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002587- Bug #1110478: Revert os.environ.update to do putenv again.
2588
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002589- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2590
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002591- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2592
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002593- Enhancements to the csv module:
2594
2595 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002596 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002597 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002598 + Dialect parameter parsing has been re-implemented to improve error
2599 reporting.
2600 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2601 dictates.
2602 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002603 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002604 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002605 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2606 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002607 + reader now allows \r characters to be quoted (previously it only allowed
2608 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002609 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002610 + Dialect classes passed to the module are no longer instantiated by
2611 the module before being parsed (the former validation scheme required
2612 this, but the mechanism was unreliable).
2613 + The dialect registry now contains instances of the internal
2614 C-coded dialect type, rather than references to python objects.
2615 + the internal c-coded dialect type is now immutable.
2616 + register_dialect now accepts the same keyword dialect specifications
2617 as the reader and writer, allowing the user to register dialects
2618 without first creating a dialect class.
2619 + a configurable limit to the size of parsed fields has been added -
2620 previously, an unmatched quote character could result in the entire
2621 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002622 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002623 the parser field size limit (returning the former limit). The initial
2624 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002625 + A line_num attribute has been added to the reader object, which tracks
2626 the number of lines read from the source iterator. This is not
2627 the same as the number of records returned, as records can span
2628 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002629 + reader and writer objects were not being registered with the cyclic-GC.
2630 This has been fixed.
2631
Brett Cannone6539c42005-01-08 02:43:53 +00002632- _DummyThread objects in the threading module now delete self.__block that is
2633 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2634 lock primitives tend to be limited in number and thus should not be wasted on
2635 a _DummyThread object. Fixes bug #1089632.
2636
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002637- The imghdr module now detects Exif files.
2638
Raymond Hettinger6065d322004-12-20 23:51:53 +00002639- StringIO.truncate() now correctly adjusts the size attribute.
2640 (Bug #951915).
2641
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002642- locale.py now uses an updated locale alias table (built using
2643 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2644 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002645 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002646
Raymond Hettinger3557f422004-12-07 12:02:02 +00002647- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2648
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002649- the pickle module no longer accepts the deprecated None option in the
2650 args tuple returned by __reduce__().
2651
Brett Cannon84667c02004-12-07 03:25:18 +00002652- optparse now optionally imports gettext. This allows its use in setup.py.
2653
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002654- the pickle module no longer uses the deprecated bin parameter.
2655
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002656- the shelve module no longer uses the deprecated binary parameter.
2657
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002658- the pstats module no longer uses the deprecated ignore() method.
2659
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002660- the filecmp module no longer uses the deprecated use_statcache argument.
2661
Raymond Hettinger664347b2004-12-04 21:21:53 +00002662- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2663 extended or overridden by subclasses. Formerly, the subclassed method would
2664 be ignored by the rest of the module. (Bug #1078905).
2665
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002666- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002667 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002668
Walter Dörwald36733692004-12-22 12:50:50 +00002669- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2670 once when a size argument is given. This prevents a buffer overflow in the
2671 tokenizer with very long source lines.
2672
Barry Warsaw538561e2006-01-01 21:48:54 +00002673- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2674 immediately after creating the object, without any intervening
2675 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002676
Skip Montanaro05885812005-01-16 20:48:27 +00002677- The reconvert.quote function can now emit triple-quoted strings. The
2678 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002679
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002680- ``UserString.MutableString`` now supports negative indices in
2681 ``__setitem__`` and ``__delitem__``
2682
Greg Ward40407942005-03-05 02:53:17 +00002683- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2684 correctly.
2685
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002686- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2687 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2688 character even if the user has passed a size parameter to get a proper
2689 line ending. Remove the special handling of a "\r\n" that has been split
2690 between two lines.
2691
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002692- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2693 about illegal code points. The codec now supports PEP 293 style error
2694 handlers.
2695
Walter Dörwald78a78b02005-09-01 12:04:29 +00002696- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002697 from the input stream, so that the output is a byte string in the correct
2698 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002699
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002700- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2701 considering it exactly like a '*'.
2702
Walter Dörwald007f8df2005-10-09 19:42:27 +00002703- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2704 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002705
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002706- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2707
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002708- Patch #1413711: Certain patterns of differences were making difflib
2709 touch the recursion limit.
2710
Walter Dörwald58917a62006-03-31 15:26:22 +00002711- Bug #947906: An object oriented interface has been added to the calendar
2712 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002713 called as a script (e.g. via ``python -mcalendar``). Localized month and
2714 weekday names can be ouput (even if an exotic encoding is used) using
2715 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002716
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002717Build
2718-----
2719
Neal Norwitz602d3392006-03-31 08:21:40 +00002720- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2721 by using -mieee gcc option.
2722

2724
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002725- Build support for Win64-AMD64 was added.
2726
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002727- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2728
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002729- Patch #881820: look for openpty and forkpty also in libbsd.
2730
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002731- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2732 The zlib module is now builtin on Windows.
2733
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002734- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2735
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002736- Bug #1189330: configure did not correctly determine the necessary
2737 value of LINKCC if python was built with GCC 4.0.
2738
Trent Mick8321b422005-07-26 02:29:21 +00002739- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2740 vulnerability in zlib 1.2.1 and 1.2.2.
2741
Brett Cannon08cd5982005-04-24 22:26:38 +00002742- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2743 flags that change binary compatibility. Changes were also made to
2744 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002745 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002746
Bob Ippolitoed233462005-03-29 13:47:59 +00002747- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2748 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2749 no longer exists). This configure patch makes things right.
2750
Martin v. Löwise2713be2005-03-08 15:03:08 +00002751- Bug #1158607: Build with --disable-unicode again.
2752
Brett Cannon46d96232005-02-16 00:07:19 +00002753- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2754 defined. Discovered as a result of not being able to build on OS X.
2755
Brett Cannon516592f2004-12-07 00:42:59 +00002756- setup.py now uses the directories specified in LDFLAGS using the -L option
2757 and in CPPFLAGS using the -I option for adding library and include
2758 directories, respectively, for compiling extension modules against. This has
2759 led to the core being compiled using the values in CPPFLAGS. It also removes
2760 the need for the special-casing of both DarwinPorts and Fink for darwin since
2761 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2762 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2763 Fink, ``-I/opt/local/include`` for DarwinPorts).
2764
Brett Cannon43802422005-02-10 20:48:03 +00002765- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2766 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2767 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2768 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002770C API
2771-----
2772
Tim Petersc9d78aa2006-03-26 23:27:58 +00002773- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2774 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2775 is obtained via the ``PyObject_`` family, it must be released via the
2776 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2777 always been officially true, but when Python's small-object allocator was
2778 introduced, an attempt was made to cater to a few extension modules
2779 discovered at the time that obtained memory via ``PyObject_New`` but
2780 released it via ``PyMem_DEL``. It's years later, and if such code still
2781 exists it will fail now (probably with segfaults, but calling wrong
2782 low-level memory management functions can yield many symptoms).
2783
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002784- Added a C API for set and frozenset objects.
2785
Raymond Hettinger66517482004-12-03 11:45:13 +00002786- Removed PyRange_New().
2787
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002788- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2789 mapping argument now. This string is used as a mapping table. Byte values
2790 greater than the length of the string and 0xFFFE are treated as undefined
2791 mappings.

2851 vimrc to it (was previous up a level).
2852
Georg Brandl56897312005-08-24 18:32:30 +00002853- Added two new files to Tools/scripts: pysource.py, which recursively
