Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
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
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000015- When __slots__ are set to a unicode string, make it work the same as
16 setting a plain string, ie don't expand to single letter identifiers.
17
Raymond Hettinger13936692007-04-11 18:40:58 +000018- Request #1191699: Slices can now be pickled.
19
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000020- Request #1193128: str.translate() now allows a None argument for
21 translations that only remove characters without re-mapping the
22 remaining characters.
23
Georg Brandl5cb76c12007-03-21 09:00:39 +000024- Patch #1682205: a TypeError while unpacking an iterable is no longer
25 masked by a generic one with the message "unpack non-sequence".
26
Neal Norwitzaa754b72007-03-21 06:39:48 +000027- Remove unused file Python/fmod.c.
28
Guido van Rossum143b5642007-03-23 04:58:42 +000029- Bug #1683368: The object.__init__() and object.__new__() methods are
30 now stricter in rejecting excess arguments. The only time when
31 either allows excess arguments is when it is not overridden and the
32 other one is. For backwards compatibility, when both are
33 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000034 warning later). Also, type.__init__() insists on the same signature
35 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000036
Georg Brandl2b869942007-03-17 16:08:45 +000037- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
38 to complex using its __complex__() method before falling back to the
39 __float__() method. Therefore, the functions in the cmath module now
40 can operate on objects that define a __complex__() method.
41
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000042- Patch #1623563: allow __class__ assignment for classes with __slots__.
43 The old and the new class are still required to have the same slot names.
44
Collin Winter77c67bd2007-03-16 04:11:30 +000045- Patch #1642547: Fix an error/crash when encountering syntax errors in
46 complex if statements.
47
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000048- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
49 is called with an object that is faking its type.
50
Žiga Seilnacht71436f02007-03-14 12:24:09 +000051- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
52 name.
53
Georg Brandl5240d742007-03-13 20:46:32 +000054- Patch #1444529: the builtin compile() now accepts keyword arguments.
55
Georg Brandl7b9c5552007-03-12 14:30:05 +000056- Bug #1678647: write a newline after printing an exception in any
57 case, even when converting the value to a string failed.
58
Georg Brandl871f1bc2007-03-12 13:17:36 +000059- The dir() function has been extended to call the __dir__() method on
60 its argument, if it exists. If not, it will work like before. This allows
61 customizing the output of dir() in the presence of a __getattr__().
62
Collin Winter276887b2007-03-12 16:11:39 +000063- Patch #922167: Python no longer segfaults when faced with infinitely
64 self-recursive reload() calls (as reported by bug #742342).
65
Žiga Seilnacht89032082007-03-11 15:54:54 +000066- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
67
Collin Wintere38051d2007-03-09 20:33:07 +000068- Patch #1491866: change the complex() constructor to allow parthensized
69 forms. This means complex(repr(x)) now works instead of raising a
70 ValueError.
71
Georg Brandlaa2321b2007-03-07 00:40:28 +000072- Patch #703779: unset __file__ in __main__ after running a file. This
73 makes the filenames the warning module prints much more sensible when
74 a PYTHONSTARTUP file is used.
75
Georg Brandl49aafc92007-03-07 00:34:46 +000076- Variant of patch #697613: don't exit the interpreter on a SystemExit
77 exception if the -i command line option or PYTHONINSPECT environment
78 variable is given, but break into the interactive interpreter just like
79 on other exceptions or normal program exit.
80
Georg Brandl00cd8182007-03-06 18:41:12 +000081- Patch #1638879: don't accept strings with embedded NUL bytes in long().
82
Georg Brandl098cd692007-03-06 12:17:50 +000083- Bug #1674503: close the file opened by execfile() in an error condition.
84
Georg Brandl0fca97a2007-03-05 22:28:08 +000085- Patch #1674228: when assigning a slice (old-style), check for the
86 sq_ass_slice instead of the sq_slice slot.
87
Neal Norwitz88516a62007-02-26 22:41:45 +000088- When printing an unraisable error, don't print exceptions. before the name.
89 This duplicates the behavior whening normally printing exceptions.
90
Martin v. Löwisfd963262007-02-09 12:19:32 +000091- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
92
Brett Cannon129bd522007-01-30 21:34:36 +000093- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
94 catch a string exception raises DeprecationWarning.
95
Brett Cannonf5bee302007-01-23 23:21:22 +000096- Bug #1377858: Fix the segfaulting of the interpreter when an object created
97 a weakref on itself during a __del__ call for new-style classes (classic
98 classes still have the bug).
99
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000100- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
101 frame's thread state.
102
Thomas Wouters6ed19652007-01-23 13:50:49 +0000103- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py

106
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000107- Prevent seg fault on shutdown which could occur if an object
108 raised a warning.
109
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000110- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
111 to avoid relying on atexit.
112
Raymond Hettinger94547f72006-12-20 06:42:06 +0000113- Bug #1590891: random.randrange don't return correct value for big number
114
Georg Brandl283a1352006-11-19 08:48:30 +0000115- Patch #1586791: Better exception messages for some operations on strings,

123
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000124- Bug #1576657: when setting a KeyError for a tuple key, make sure that
125 the tuple isn't used as the "exception arguments tuple".
126
Neal Norwitz21997af2006-10-28 21:19:07 +0000127- Bug #1565514, SystemError not raised on too many nested blocks.
128
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000129- Bug #1576174: WindowsError now displays the windows error code
130 again, no longer the posix error code.
131
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000132- Patch #1549049: Support long values in structmember, issue warnings
133 if the assigned value for structmember fields gets truncated.
134
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000135- Update the peephole optimizer to remove more dead code (jumps after returns)
136 and inline unconditional jumps to returns.
137
Georg Brandl2c1375c2006-10-12 11:27:59 +0000138- Bug #1545497: when given an explicit base, int() did ignore NULs
139 embedded in the string to convert.
140
Georg Brandl846f73a2006-10-08 07:11:54 +0000141- Bug #1569998: break inside a try statement (outside a loop) is now
142 recognized and rejected.
143
Armin Rigo7ccbca92006-10-04 12:17:45 +0000144- list.pop(x) accepts any object x following the __index__ protocol.
145
146- Fix some leftovers from the conversion from int to Py_ssize_t
147 (relevant to strings and sequences of more than 2**31 items).
148
149- A number of places, including integer negation and absolute value,
150 were fixed to not rely on undefined behaviour of the C compiler
151 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000152
Georg Brandl3267d282006-09-30 09:03:42 +0000153- Bug #1566800: make sure that EnvironmentError can be called with any

169
Brett Cannon9adeab72006-09-20 18:34:28 +0000170- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
171 allows calling unicode() on exceptions classes directly to succeed.
172
Georg Brandlec6c2df2006-09-11 09:38:35 +0000173- Make _PyGILState_NoteThreadState() static, it was not used anywhere

181 imports (if not in package and if beyond toplevel package).
182
Tim Petersc10c9d02006-09-05 02:18:09 +0000183- Overflow checking code in integer division ran afoul of new gcc
184 optimizations. Changed to be more standard-conforming.

191 head is the original string if sep was not found.
192
Neal Norwitzdac090d2006-09-05 03:53:08 +0000193- Bug #1520864: unpacking singleton tuples in list comprehensions and
194 generator expressions (x for x, in ... ) works again. Fixing this problem
195 required changing the .pyc magic number. This means that .pyc files
196 generated before 2.5c2 will be regenerated.
197

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000202- Add new requirements for metaclasses. 1) If type or a subclass of type
203 occurs in __bases__, it must occur before any non-type bases, e.g.
204 before regular classes. 2) If you assign to __bases__, you may not
205 change the metaclass. Many more illegal assignments to __bases__
206 are now checked and raise TypeErrors. This changed fixed at least
207 one known crash.
208
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +0000209Library

238 GNOME or KDE browser, depending on whether there is a session of one
239 of those present. Also, it tries the Windows default browser before
240 trying Mozilla variants.
241
Collin Winter6f187742007-03-16 22:16:08 +0000242- Patch #1339796: add a relpath() function to os.path.

327
Georg Brandl9caadf82007-03-08 18:37:31 +0000328- unittest now verifies more of its assumptions. In particular, TestCase
329 and TestSuite subclasses (not instances) are no longer accepted in
330 TestSuite.addTest(). This should cause no incompatibility since it

Guido van Rossumc69ac252006-08-10 18:09:25 +0000845What's New in Python 2.5 release candidate 1?
846=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000847
Anthony Baxterb4096662006-08-16 03:42:26 +0000848*Release date: 17-AUG-2006*

850Core and builtins
851-----------------
852
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000853- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000854 compared equal or unequal to a string and a UnicodeDecodeError
855 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000856
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000857 Instead, the equal (==) and unequal (!=) comparison operators will
858 now issue a UnicodeWarning and interpret the two objects as
859 unequal. The UnicodeWarning can be filtered as desired using
860 the warning framework, e.g. silenced completely, turned into an
861 exception, logged, etc.
862
863 Note that compare operators other than equal and unequal will still
864 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000865

873
874- Patch #1538606, Fix __index__() clipping. There were some problems

876 were handled. This patch attempts to provide enough alternatives
877 to effectively use __index__.
878
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000879- Bug #1536021: __hash__ may now return long int; the final hash
880 value is obtained by invoking hash on the long int.
881
Thomas Hellerab1049c2006-08-08 17:37:00 +0000882- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Neal Norwitz4ffedad2006-08-04 04:58:47 +0000890- Bug #1191458: tracing over for loops now produces a line event
891 on each iteration. Fixing this problem required changing the .pyc
892 magic number. This means that .pyc files generated before 2.5c1
893 will be regenerated.
894
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000895- Bug #1333982: string/number constants were inappropriately stored
896 in the byte code and co_consts even if they were not used, ie
897 immediately popped off the stack.
898
Georg Brandle9462c72006-08-04 18:03:37 +0000899- Fixed a reference-counting problem in property().

902Library
903-------
904
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000905- Fix a bug in the ``compiler`` package that caused invalid code to be
906 generated for generator expressions.
907
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000908- The distutils version has been changed to 2.5.0. The change to
909 keep it programmatically in sync with the Python version running
910 the code (introduced in 2.5b3) has been reverted. It will continue
911 to be maintained manually as static string literal.
912
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000913- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000914 and this cannot be converted to the required C type, an exception is
915 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000916 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000917
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000918- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000919 an exception.
920
Tim Petersc10c9d02006-09-05 02:18:09 +0000921- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000922 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000923 workarounds for clocks with low resolution, to stop the code yielding
924 duplicate UUIDs.
925
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000926- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
927 before raising SystemExit, allowing IDLE to honor quit() and exit().
928
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000929- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
930
Georg Brandl7a1af772006-08-14 21:55:28 +0000931- Patch #1536071: trace.py should now find the full module name of a
932 file correctly even on Windows.
933
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000934- logging's atexit hook now runs even if the rest of the module has
935 already been cleaned up.
936
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000937- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000938
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000939- Bug #1531405, format_exception no longer raises an exception if
940 str(exception) raised an exception.
941
Neil Schemenauer06ded092006-08-04 16:20:30 +0000942- Fix a bug in the ``compiler`` package that caused invalid code to be
943 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000951- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
952 raises the correct exceptions.
953
Thomas Heller1ce433e2006-08-14 16:20:04 +0000954- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
955 '-no-stack-protector' compiler flag for OpenBSD has been removed.
956
Thomas Heller86720042006-08-14 11:17:48 +0000957- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
958 uses the _as_parameter_ attribute when objects are passed to foreign
959 function calls. The ctypes version number was changed to 1.0.1.
960
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000961- Bug #1530559, struct.pack raises TypeError where it used to convert.
962 Passing float arguments to struct.pack when integers are expected
963 now triggers a DeprecationWarning.
964
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000965

987-----
988
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000989- Bug #1535502, build _hashlib on Windows, and use masm assembler
990 code in OpenSSL.
991
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000992- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
993
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000994- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000996
Tim Peters4643c2f2006-08-10 22:45:34 +0000997C API
998-----
999
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001000- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1001
Tim Peters4643c2f2006-08-10 22:45:34 +00001002- Bug #1069160. Internal correctness changes were made to
1003 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1004 the documentation was changed to state that the return value
1005 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001008What's New in Python 2.5 beta 3?
1009================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001010
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001011*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001012
1013Core and builtins
1014-----------------
1015
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001016- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001017 returned a long (see PEP 353).
1018
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001019- Bug #1515471: string.replace() accepts character buffers again.
1020
Neal Norwitz07aadb12006-07-30 06:55:48 +00001021- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1022 This provides the proper warning for struct.pack().
1023 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1024
Neal Norwitz0d62a062006-07-30 06:53:31 +00001025- Patch #1531113: Fix augmented assignment with yield expressions.
1026 Also fix a SystemError when trying to assign to yield expressions.
1027
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001028- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1029 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1030 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1031 excessive filesystem operations during imports.
1032
Tim Petersbc24eee2006-07-27 01:14:53 +00001033- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1034 operations on signed longs that are formally undefined by C.
1035 Unfortunately, at least one compiler now cares about that, so complicated
1036 the code to make that compiler happy again.
1037
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001038- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1039
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001040- Patch #1232023: Stop including current directory in search
1041 path on Windows.
1042
Neal Norwitze1fdb322006-07-21 05:32:28 +00001043- Fix some potential crashes found with failmalloc.
1044
Neal Norwitze7563102006-07-17 01:00:16 +00001045- Fix warnings reported by Klocwork's static analysis tool.
1046
Neal Norwitz84be93b2006-07-16 01:50:38 +00001047- Bug #1512814, Fix incorrect lineno's when code within a function
1048 had more than 255 blank lines.
1049
Georg Brandl9dceedb2006-07-12 15:31:17 +00001050- Patch #1521179: Python now accepts the standard options ``--help`` and
1051 ``--version`` as well as ``/?`` on Windows.
1052
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001053- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001054 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001055 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001056
Tim Peters112aad32006-07-19 00:03:19 +00001057- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001058 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001059 new ``sys._current_frames()`` returns a dictionary with one entry,
1060 mapping the faux "thread id" 0 to the current frame.
1061
Ronald Oussoren3075e162006-07-25 20:28:55 +00001062- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001063
Ronald Oussoren3075e162006-07-25 20:28:55 +00001064
Neal Norwitza1f10902006-07-12 07:28:29 +00001065Library
1066-------
1067
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001068- Correction of patch #1455898: In the mbcs decoder, set final=False
1069 for stream decoder, but final=True for the decode function.
1070
Georg Brandl07fec3a2006-08-01 18:49:24 +00001071- os.urandom no longer masks unrelated exceptions like SystemExit or
1072 KeyboardInterrupt.
1073
Tim Peters4643c2f2006-08-10 22:45:34 +00001074- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001075 shutil.copytree on Windows
1076
Georg Brandle34ac7c2006-07-30 11:07:23 +00001077- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1078 refers to file descriptors, not file objects.
1079
Tim Petersc10c9d02006-09-05 02:18:09 +00001080- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001081 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001082 #1513611, and probably others.
1083
Georg Brandledd9b0d2006-07-29 09:33:26 +00001084- Bug #1441397: The compiler module now recognizes module and function
1085 docstrings correctly as it did in Python 2.4.
1086
Tim Peters6f681472006-07-27 23:44:37 +00001087- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1088 lost that tests are sorted by name before being run. This rarely
1089 matters for well-written tests, but can create baffling symptoms if
1090 side effects from one test to the next affect outcomes. ``DocTestFinder``
1091 has been changed to sort the list of tests it returns.
1092
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001093- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001094 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001095
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001096- Bug #978833: Really close underlying socket in _socketobject.close.
1097
Georg Brandl8c036cc2006-08-20 13:15:39 +00001098- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1099 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001100
Georg Brandlcf0c1722006-07-26 07:23:32 +00001101- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1102 to recursive calls and call it with the failing package name.
1103
Martin v. Löwis0b483032006-07-25 09:53:12 +00001104- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1105
Georg Brandlc13c34c2006-07-24 14:09:56 +00001106- Patch #1515343: Fix printing of deprecated string exceptions with a
1107 value in the traceback module.
1108
Greg Ward48fae7a2006-07-23 16:05:51 +00001109- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1110
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001111- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1112
Brett Cannoncaebe222006-07-18 04:41:36 +00001113- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1114 argument tuple. For arguments where zero is illegal, the value is forced to
1115 the minimum value that is correct. This is to support an undocumented but
1116 common way people used to fill in inconsequential information in the time
1117 tuple pre-2.4.
1118
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001119- Patch #1220874: Update the binhex module for Mach-O.
1120
Barry Warsawb110bad2006-07-21 14:51:07 +00001121- The email package has improved RFC 2231 support, specifically for
1122 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1123 (name*0=<blah>) parameter continuations. This may change the types of
1124 values returned from email.message.Message.get_param() and friends.
1125 Specifically in some cases where non-encoded continuations were used,
1126 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1127 will just return the string (since non-encoded continuations don't have
1128 charset and language parts).
1129
1130 Also, whereas % values were decoded in all parameter continuations, they are
1131 now only decoded in encoded parameter parts.
1132
Ronald Oussoren3075e162006-07-25 20:28:55 +00001133- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1134
1135- Bug #1517996: IDLE now longer shows the default Tk menu when a
1136 path browser, class browser or debugger is the frontmost window on MacOS X
1137
Barry Warsaw00decd72006-07-27 23:43:15 +00001138- Patch #1520294: Support for getset and member descriptors in types.py,
1139 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1140 of an object against these built-in types and more importantly, for getting
1141 their docstrings printed in the interactive interpreter's help() function.

1145-----------------
1146
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001147- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1148 a socket operation on a socket with a timeout, the exception will be
1149 caught correctly. Previously, the exception was not caught.
1150
Thomas Heller1393d6a2006-07-28 21:43:20 +00001151- Patch #1529514: The _ctypes extension is now compiled on more
1152 openbsd target platforms.
1153
Tim Peters9cab5932006-07-28 00:30:00 +00001154- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1155 a memory leak, affecting pickles and deep copies.
1156
Tim Petersbc24eee2006-07-27 01:14:53 +00001157- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001158 Paul Eggert.
1159
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001160- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1161
Thomas Hellerce049a02006-07-14 17:51:14 +00001162- Patch #1521817: Index range checking on ctypes arrays containing
1163 exactly one element enabled again. This allows iterating over these
1164 arrays, without the need to check the array size before.
1165
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001166- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001167 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001168 /dev/null in certain cases; this is now fixed.
1169
Thomas Heller47d7a062006-07-12 08:43:47 +00001170- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1171 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001172
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001173- Because of a misspelled preprocessor symbol, ctypes was always
1174 compiled without thread support; this is now fixed.
1175
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001176- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1177 methods now allow their database parameter to be None as the
1178 sleepycat API allows.
1179
Matt Flemingec926502006-07-28 11:27:27 +00001180- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1181 bluetooth API compared with Linux and FreeBSD.
1182
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001183Tests
1184-----
1185
1186- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1187 how long the test file should take to play. Now accepts taking 2.93 secs
1188 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1189
Georg Brandl4793aa32006-07-28 18:31:39 +00001190- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1191 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1192 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001193
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001194Build
1195-----
1196
1197- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1198
Ronald Oussoren26cad082006-08-01 21:00:57 +00001199Mac
1200---
1201
1202- PythonLauncher now works correctly when the path to the script contains
1203 characters that are treated specially by the shell (such as quotes).
1204
1205- Bug #1527397: PythonLauncher now launches scripts with the working directory
1206 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001207 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001208 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001215
1216Core and builtins
1217-----------------
1218
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001219- Bug #1441486: The literal representation of -(sys.maxint - 1)
1220 again evaluates to a int object, not a long.
1221
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001222- Bug #1501934: The scope of global variables that are locally assigned
1223 using augmented assignment is now correctly determined.
1224
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001225- Bug #927248: Recursive method-wrapper objects can now safely
1226 be released.
1227
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001228- Bug #1417699: Reject locale-specific decimal point in float()
1229 and atof().
1230
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001231- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1232 omit a default "error" argument for NULL pointer. This allows
1233 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001234
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001235- Bug #1519018: 'as' is now validated properly in import statements.
1236
Neal Norwitz28746ab2006-07-09 22:14:42 +00001237- On 64 bit systems, int literals that use less than 64 bits are
1238 now ints rather than longs.
1239
Neal Norwitzed657552006-07-10 00:04:44 +00001240- Bug #1512814, Fix incorrect lineno's when code at module scope
1241 started after line 256.
1242
Tim Peters32a83612006-07-10 21:08:24 +00001243- New function ``sys._current_frames()`` returns a dict mapping thread
1244 id to topmost thread stack frame. This is for expert use, and is
1245 especially useful for debugging application deadlocks. The functionality
1246 was previously available in Fazal Majid's ``threadframe`` extension
1247 module, but it wasn't possible to do this in a wholly threadsafe way from
1248 an extension.
1249

1257
Tim Peters32a83612006-07-10 21:08:24 +00001258- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001259 environment variable to be set in order to the SDK environment
1260 for finding the compiler, include files, etc.

1265
Thomas Woutersadd19112006-07-05 11:03:49 +00001266- string.Template() now correctly handles tuple-values. Previously,
1267 multi-value tuples would raise an exception and single-value tuples would
1268 be treated as the value they contain, instead.
1269
Martin v. Löwisede77f52006-07-03 13:01:35 +00001270- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1271 even if some data are received.
1272
Martin v. Löwis45482392006-07-03 12:28:58 +00001273- Bug #1267547: Put proper recursive setup.py call into the
1274 spec file generated by bdist_rpm.
1275
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001276- Bug #1514693: Update turtle's heading when switching between
1277 degrees and radians.
1278
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001279- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001280 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001281
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001282- Bug #1514703: Only setup canvas window in turtle when the canvas
1283 is created.
1284
Martin v. Löwis7596e832006-07-01 15:33:37 +00001285- Bug #1513223: .close() of a _socketobj now releases the underlying
1286 socket again, which then gets closed as it becomes unreferenced.

1289 attribute values.
1290
1291- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1292 sgmllib ('[' and ']' were not accepted).
1293
Georg Brandl1be63af2006-06-28 20:23:25 +00001294- Fix a bug in the turtle module's end_fill function.
1295
Brett Cannon53ab5b72006-06-22 16:49:14 +00001296- Bug #1510580: The 'warnings' module improperly required that a Warning
1297 category be either a types.ClassType and a subclass of Warning. The proper
1298 check is just that it is a subclass with Warning as the documentation states.
1299
Georg Brandlad29e632006-06-21 17:45:17 +00001300- The compiler module now correctly compiles the new try-except-finally
1301 statement (bug #1509132).
1302
Neal Norwitz60373cd2006-06-22 06:30:50 +00001303- The wsgiref package is now installed properly on Unix.
1304
Vinay Sajip28e57612006-07-01 10:45:20 +00001305- A bug was fixed in logging.config.fileConfig() which caused a crash on
1306 shutdown when fileConfig() was called multiple times.
1307
Gerhard Häring762fbd32006-07-02 17:48:30 +00001308- The sqlite3 module did cut off data from the SQLite database at the first
1309 null character before sending it to a custom converter. This has been fixed
1310 now.
1311
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001312Extension Modules
1313-----------------
1314
Tim Peters112aad32006-07-19 00:03:19 +00001315- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1316 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1317 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001318
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001319- Assigning None to pointer type fields in ctypes structures possible
1320 overwrote the wrong fields, this is fixed now.
1321
1322- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1323 on non-Windows platforms.
1324
1325- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1326 integer or long, without range checking.
1327
1328- Patch #1517790: It is now possible to use custom objects in the ctypes
1329 foreign function argtypes sequence as long as they provide a from_param
1330 method, no longer is it required that the object is a ctypes type.
1331
1332- The '_ctypes' extension module now works when Python is configured
1333 with the --without-threads option.
1334
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001335- Bug #1513646: os.access on Windows now correctly determines write
1336 access, again.
1337
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001338- Bug #1512695: cPickle.loads could crash if it was interrupted with
1339 a KeyboardInterrupt.
1340
Neal Norwitza12aa882006-07-06 06:45:08 +00001341- Bug #1296433: parsing XML with a non-default encoding and
1342 a CharacterDataHandler could crash the interpreter in pyexpat.
1343
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001344- Patch #1516912: improve Modules support for OpenVMS.

1347-----
1348
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001349- Automate Windows build process for the Win64 SSL module.
1350
Tim Peters32a83612006-07-10 21:08:24 +00001351- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001352 Previously, the slight difference could cause compilation errors of the
1353 'zlib' module on systems with more than one version of zlib.
1354
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001355- The MSI compileall step was fixed to also support a TARGETDIR
1356 with spaces in it.
1357
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001358- Bug #1517388: sqlite3.dll is now installed on Windows independent
1359 of Tcl/Tk.
1360
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001361- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001362 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001363
Neal Norwitzb15ac312006-06-29 04:10:08 +00001364Tests
1365-----
1366
1367- Call os.waitpid() at the end of tests that spawn child processes in order
1368 to minimize resources (zombies).
1369
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001370Documentation
1371-------------
1372
Nick Coghlan2d792252006-07-06 13:47:18 +00001373- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1374 documentation for the warnings module.
1375
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001376- Patch #1509163: MS Toolkit Compiler no longer available.
1377

Nick Coghlanc649ec52006-05-29 12:43:05 +00001381What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001382================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001383
Anthony Baxterd1136802006-06-19 12:04:15 +00001384*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001385
1386Core and builtins
1387-----------------
1388
Georg Brandla56b9152006-06-19 06:35:54 +00001389- Patch #1507676: Error messages returned by invalid abstract object operations
1390 (such as iterating over an integer) have been improved and now include the
1391 type of the offending object to help with debugging.
1392
Brett Cannonea3912b2006-06-13 21:46:41 +00001393- Bug #992017: A classic class that defined a __coerce__() method that returned
1394 its arguments swapped would infinitely recurse and segfault the interpreter.
1395
Neal Norwitz909eb122006-06-12 02:13:21 +00001396- Fix the socket tests so they can be run concurrently.
1397
Neal Norwitzb9845e72006-06-12 02:11:18 +00001398- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001399 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001400
Brett Cannon22565aa2006-06-09 22:31:23 +00001401- Bug #532646: object.__call__() will continue looking for the __call__
1402 attribute on objects until one without one is found. This leads to recursion
1403 when you take a class and set its __call__ attribute to an instance of the
1404 class. Originally fixed for classic classes, but this fix is for new-style.
1405 Removes the infinite_rec_3 crasher.
1406
Georg Brandl24250812006-06-09 18:45:48 +00001407- The string and unicode methods startswith() and endswith() now accept
1408 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1409
Brett Cannonde3b0522006-06-08 17:00:45 +00001410- Buffer objects, at the C level, never used the char buffer
1411 implementation even when the char buffer for the wrapped object was
1412 explicitly requested (originally returned the read or write buffer).
1413 Now a TypeError is raised if the char buffer is not present but is
1414 requested.
1415
Georg Brandlddbaa662006-06-04 21:56:52 +00001416- Patch #1346214: Statements like "if 0: suite" are now again optimized
1417 away like they were in Python 2.4.
1418
Georg Brandlb7c8f542006-05-27 12:30:25 +00001419- Builtin exceptions are now full-blown new-style classes instead of
1420 instances pretending to be classes, which speeds up exception handling
1421 by about 80% in comparison to 2.5a2.
1422
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001423- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1424 Unicode 4.1.
1425
Georg Brandlf4ef1162006-05-26 18:03:31 +00001426- Patch #921466: sys.path_importer_cache is now used to cache valid and
1427 invalid file paths for the built-in import machinery which leads to
1428 fewer open calls on startup.
1429
Tim Peters696cf432006-05-24 21:10:40 +00001430- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1431 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1432 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1433 the number of input digits (it was and remains linear-time for bases
1434 2, 4, 8, 16 and 32).
1435
Tim Petersb713ec22006-05-23 18:45:30 +00001436- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1437 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1438 an integer close to ``sys.maxint``. This was repaired by patch
1439 #1335972, which also gives a nice speedup.
1440
Richard Jonescebbefc2006-05-23 18:28:17 +00001441- Patch #1337051: reduced size of frame objects.
1442
1443- PyErr_NewException now accepts a tuple of base classes as its
1444 "base" parameter.
1445
Richard Jones7c88dcc2006-05-23 10:37:38 +00001446- Patch #876206: function call speedup by retaining allocated frame
1447 objects.
1448
Georg Brandl7b90e162006-05-18 07:01:27 +00001449- Bug #1462152: file() now checks more thoroughly for invalid mode
1450 strings and removes a possible "U" before passing the mode to the
1451 C library function.
1452
Neal Norwitz1004a532006-05-15 07:17:23 +00001453- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1454
Neal Norwitz373f0a72006-05-15 07:04:36 +00001455- Bug #1487966: Fix SystemError with conditional expression in assignment
1456
Martin v. Löwis879768d2006-05-11 13:28:43 +00001457- WindowsError now has two error code attributes: errno, which carries
1458 the error values from errno.h, and winerror, which carries the error
1459 values from winerror.h. Previous versions put the winerror.h values
1460 (from GetLastError()) into the errno attribute.
1461
Martin v. Löwis77736712006-05-04 05:51:03 +00001462- Patch #1475845: Raise IndentationError for unexpected indent.
1463
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001464- Patch #1479181: split open() and file() from being aliases for each other.
1465
Tim Peters44bd9862006-06-01 13:49:23 +00001466- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1467 methods were always silently ignored by dictionaries when comparing keys.
1468 They are now passed through (except when using the C API function
1469 ``PyDict_GetItem()``, whose semantics did not change).
1470
1471- Bug #1456209: In some obscure cases it was possible for a class with a
1472 custom ``__eq__()`` method to confuse dict internals when class instances
1473 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1474 No, you don't have any code that did this ;-)

1477-----------------
1478
Trent Mick960a3f82006-06-28 20:30:41 +00001479- Bug #1295808: expat symbols should be namespaced in pyexpat
1480
1481- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1482
Brett Cannon6ee7d012006-06-08 16:23:04 +00001483- Change binascii.hexlify to accept a read-only buffer instead of only a char
1484 buffer and actually follow its documentation.
1485
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001486- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1487
Nick Coghlanc649ec52006-05-29 12:43:05 +00001488- Patch #1478788 (modified version): The functional extension module has
1489 been renamed to _functools and a functools Python wrapper module added.
1490 This provides a home for additional function related utilities that are
1491 not specifically about functional programming. See PEP 309.
1492
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001493- Patch #1493701: performance enhancements for struct module.
1494
Georg Brandl378d5922006-05-17 14:26:50 +00001495- Patch #1490224: time.altzone is now set correctly on Cygwin.
1496
Georg Brandl8d3342b2006-05-16 07:38:27 +00001497- Patch #1435422: zlib's compress and decompress objects now have a
1498 copy() method.
1499
Andrew MacIntyre92913322006-06-13 15:04:24 +00001500- Patch #1454481: thread stack size is now tunable at runtime for thread
1501 enabled builds on Windows and systems with Posix threads support.
1502
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001503- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1504 (up to the system limit of 32K characters).
1505
1506- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1507 As a result, these functions now raise WindowsError instead of OSError.
1508
Tim Peters7a822da2006-05-25 21:50:17 +00001509- ``time.clock()`` on Win64 should use the high-performance Windows
1510 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1511 Windows platforms).
1512
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001513- Calling Tk_Init twice is refused if the first call failed as that
1514 may deadlock.
1515
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001516- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1517 accept it without potentially using an uninitialized pointer.
1518
1519- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1520 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1521 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001522
Gregory P. Smith372b5832006-06-05 18:48:21 +00001523- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001524 [pybsddb project SF patch number 1466734]
1525
Gregory P. Smith372b5832006-06-05 18:48:21 +00001526- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1527 parameter is supplied. [SF pybsddb bug #1477863]
1528
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001529- bsddb: the __len__ method of a DB object has been fixed to return correct
1530 results. It could previously incorrectly return 0 in some cases.
1531 Fixes SF bug 1493322 (pybsddb bug 1184012).
1532
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001533- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1534 aborts the db transaction safely when a modifier callback fails.
1535 Fixes SF python patch/bug #1408584.
1536
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001537- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001538 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001539 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1540 database calls that would previously deadlock. [SF python bug #775414]
1541
Vinay Sajip28e57612006-07-01 10:45:20 +00001542- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001543
Walter Dörwald4994d952006-06-19 08:07:50 +00001544- Patch #1506645: add Python wrappers for the curses functions
1545 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001550- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1551 functions.
1552
Martin v. Löwis3798da02006-06-17 18:44:27 +00001553- Patch #812986: Update turtle output even if not tracing.
1554
Vinay Sajip28e57612006-07-01 10:45:20 +00001555- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001556 Tkinter.BaseWidget.
1557
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001558- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1559
Martin v. Löwis337487e2006-06-17 09:15:14 +00001560- Patch #763580: Add name and value arguments to Tkinter variable
1561 classes.
1562
Georg Brandl83cc0d02006-06-14 08:50:03 +00001563- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1564 mime.types file for determining MIME types.
1565
Georg Brandl2605ca82006-06-14 06:08:31 +00001566- Bug #1339007: Shelf objects now don't raise an exception in their
1567 __del__ method when initialization failed.
1568
Martin v. Löwisd8251432006-06-14 05:21:04 +00001569- Patch #1455898: The MBCS codec now supports the incremental mode for
1570 double-byte encodings.
1571
Tim Peters43898b42006-06-14 04:09:25 +00001572- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1573 guarantee that adjacent triples in the return list always describe
1574 non-adjacent blocks. Previously, a pair of matching blocks could end
1575 up being described by multiple adjacent triples that formed a partition
1576 of the matching pair.
1577
Greg Ward0e0c9f42006-06-11 16:24:11 +00001578- Bug #1498146: fix optparse to handle Unicode strings in option help,
1579 description, and epilog.
1580
Greg Wardd1c797e2006-06-11 14:42:41 +00001581- Bug #1366250: minor optparse documentation error.
1582
Greg Ward7f547402006-06-11 00:40:49 +00001583- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1584 clarify docs.
1585
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001586- The wsgiref package has been added to the standard library.
1587
Nick Coghlan676725d2006-06-08 13:54:49 +00001588- The functions update_wrapper() and wraps() have been added to the functools
1589 module. These make it easier to copy relevant metadata from the original
1590 function when writing wrapper functions.
1591
Tim Petersd6a9eef2006-06-05 01:48:21 +00001592- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1593 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001594
Martin v. Löwis3f767792006-06-04 19:36:28 +00001595- Patch #1359618: Speed up charmap encoder by using a trie structure
1596 for lookup.
1597
Tim Petersd609b1a2006-06-02 23:22:51 +00001598- The functions in the ``pprint`` module now sort dictionaries by key
1599 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1600 if and only if its display required more than one line, although that
1601 wasn't documented. The new behavior increases predictability; e.g.,
1602 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1603
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001604- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1605 (thanks for J. J. Lee).
1606
Georg Brandl2b330372006-05-28 20:23:12 +00001607- Patch #1496206: improve urllib2 handling of passwords with respect to
1608 default HTTP and HTTPS ports.
1609
George Yoshidaf3c65de2006-05-28 16:39:09 +00001610- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1611
Bob Ippolito7298f272006-05-23 18:43:47 +00001612- Patch #1281707: speed up gzip.readline.
1613
Georg Brandlb89316f2006-05-17 15:51:16 +00001614- Patch #1180296: Two new functions were added to the locale module:
1615 format_string() to get the effect of "format % items" but locale-aware,
1616 and currency() to format a monetary number with currency sign.
1617
Georg Brandle3a25832006-05-17 14:56:04 +00001618- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1619 and several features added, such as speed and geometry control.
1620
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001621- Patch #1488881: add support for external file objects in bz2 compressed
1622 tarfiles.
1623
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001624- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1625 stdout arguments, making it possible to redirect input and output
1626 for remote debugging.
1627
1628- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1629 a couple of issues, notably handling of long file names using the
1630 GNU LONGNAME extension.
1631
1632- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1633 new flag when ``name`` is already the name of an option flag.
1634
1635- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1636 package.
1637
1638- Patch #1472854: make the rlcompleter.Completer class usable on non-
1639 UNIX platforms.
1640
1641- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1642
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001643- Bug #1472827: correctly escape newlines and tabs in attribute values in

1679Core and builtins
1680-----------------
1681
Thomas Heller1b046642006-04-18 18:51:06 +00001682- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1683 by converting these apis from macros into exported functions again:
1684
1685 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1686 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1687 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1688 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1689 PyRun_String Py_CompileString
1690
Martin v. Löwis45294a92006-04-18 06:24:08 +00001691- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1692
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001693- All uses of PyStructSequence_InitType have been changed to initialize
1694 the type objects only once, even if the interpreter is initialized
1695 multiple times.
1696
Neal Norwitz61546162006-04-14 05:20:28 +00001697- Bug #1454485, array.array('u') could crash the interpreter. This was
1698 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1699 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1700
1701- Py_UNICODE is unsigned. It was always documented as unsigned, but
1702 due to a bug had a signed value in previous versions.
1703
Tim Peters3a5e8b12006-04-11 01:44:07 +00001704- Patch #837242: ``id()`` of any Python object always gives a positive
1705 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1706 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001707 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001708 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001709
Tim Peters3a5e8b12006-04-11 01:44:07 +00001710 def __hash__(self):
1711 return id(self) # WRONG
1712
1713 because a hash result must be a (short) Python int but it was always
1714 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001715 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001716 was always usable as a hash value before this patch. That's no longer
1717 necessarily so.
1718
1719- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001720 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001721 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001722 #1454844)
1723
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001724- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1725 involving generators that have paused outside of any ``try`` or ``with``
1726 blocks. (In 2.5a1, a paused generator that was part of a reference
1727 cycle could not be garbage collected, regardless of whether it was
1728 paused in a ``try`` or ``with`` block.)

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001736- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1737 fails with an error condition.
1738
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001739- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1740
1741- Bug #1117761: bsddb.*open() no longer raises an exception when using
1742 the cachesize parameter.
1743
1744- Bug #1149413: bsddb.*open() no longer raises an exception when using
1745 a temporary db (file=None) with the 'n' flag to truncate on open.
1746
1747- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1748 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001749
Armin Rigoa9017c32006-04-19 11:50:27 +00001750- Patch #1062014: AF_UNIX sockets under Linux have a special
1751 abstract namespace that is now fully supported.

1754-------
1755
Peter Astrand7d1d4362006-07-14 14:04:45 +00001756- Bug #1223937: subprocess.CalledProcessError reports the exit status
1757 of the process using the returncode attribute, instead of
1758 abusing errno.
1759
Tim Peters711bf302006-04-25 03:31:36 +00001760- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1761 a doctest to be skipped (the code is not run, and the expected output
1762 or exception is ignored).
1763
Nick Coghlanda2268f2006-04-24 04:37:15 +00001764- Fixed contextlib.nested to cope with exceptions being raised and
1765 caught inside exit handlers.
1766
Greg Wardab05edc2006-04-23 03:47:58 +00001767- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1768 hex, octal, or binary; add ``append_const`` action; keep going if
1769 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1770 added ``epilog`` for better help generation).
1771
Tim Peters21fbd572006-04-21 21:18:10 +00001772- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1773 called from a thread spawned as a side effect of importing a module.

Phillip J. Eby17a35f92006-04-18 16:45:14 +00001775- The pydoc module now supports documenting packages contained in
1776 .zip or .egg files.
1777
1778- The pkgutil module now has several new utility functions, such
1779 as ``walk_packages()`` to support working with packages that are either
1780 in the filesystem or zip files.
1781
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001782- The mailbox module can now modify and delete messages from
1783 mailboxes, in addition to simply reading them. Thanks to Gregory
1784 K. Johnson for writing the code, and to the 2005 Google Summer of
1785 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001786

1809
Skip Montanaro262fb922006-04-21 02:31:07 +00001810- The pstats.Stats class accepts an optional stream keyword argument to
1811 direct output to an alternate file-like object.
1812
Anthony Baxter51bcb682006-04-05 14:51:42 +00001813Build
1814-----
1815
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001816- The Makefile now has a reindent target, which runs reindent.py on
1817 the library.
1818
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001819- Patch #1470875: Building Python with MS Free Compiler
1820
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001821- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001822
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001823- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1824 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001825 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001826 CXX from --with-cxx-main, see description in README.
1827
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001828- Patch #1429775: Link extension modules with the shared libpython.
1829
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001830- Fixed a libffi build problem on MIPS systems.
1831
Tim Peters8931ff12006-05-13 23:28:20 +00001832- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1833 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1834 and "%zu" for unsigned integers of type ``size_t``.
1835
Anthony Baxter51bcb682006-04-05 14:51:42 +00001836Tests
1837-----
1838
Nick Coghlanda2268f2006-04-24 04:37:15 +00001839- test_contextlib now checks contextlib.nested can cope with exceptions
1840 being raised and caught inside exit handlers.
1841
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001842- test_cmd_line now checks operation of the -m and -c command switches
1843
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001844- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1845 it separately and by hand. It also wasn't cleaning up its changes to
1846 the current Decimal context.
1847
Thomas Woutersabd08882006-04-26 15:53:30 +00001848- regrtest.py now has a -M option to run tests that test the new limits of
1849 containers, on 64-bit architectures. Running these tests is only sensible
1850 on 64-bit machines with more than two gigabytes of memory. The argument
1851 passed is the maximum amount of memory for the tests to use.
1852
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001853Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001859Documentation
1860-------------
1861
Tim Petersb06d28c2006-05-12 01:57:59 +00001862- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1863
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001864- PEP 343: Added Context Types section to the library reference
1865 and attempted to bring other PEP 343 related documentation into
1866 line with the implementation and/or python-dev discussions.
1867
Tim Peters8dc73d22006-04-24 02:03:16 +00001868- Bug #1337990: clarified that ``doctest`` does not support examples
1869 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001872What's New in Python 2.5 alpha 1?
1873=================================
1874
Anthony Baxterebed3f62006-04-03 15:03:44 +00001875*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001876
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001877Core and builtins
1878-----------------
1879
Nick Coghlan43832302006-04-23 17:04:07 +00001880- PEP 338: -m command line switch now delegates to runpy.run_module
1881 allowing it to support modules in packages and zipfiles
1882
Martin v. Löwisc661b882006-04-20 04:54:23 +00001883- On Windows, .DLL is not an accepted file name extension for
1884 extension modules anymore; extensions are only found if they
1885 end in .PYD.
1886
Martin v. Löwisea62d252006-04-03 10:56:49 +00001887- Bug #1421664: sys.stderr.encoding is now set to the same value as
1888 sys.stdout.encoding.
1889
Neal Norwitz92e212f2006-04-03 04:48:37 +00001890- __import__ accepts keyword arguments.
1891
Georg Brandlccadf842006-03-31 18:54:53 +00001892- Patch #1460496: round() now accepts keyword arguments.
1893
Anthony Baxter262c00a2006-03-30 10:53:17 +00001894- Fixed bug #1459029 - unicode reprs were double-escaped.
1895
Hye-Shik Changd478f342006-03-23 12:32:36 +00001896- Patch #1396919: The system scope threads are reenabled on FreeBSD
1897 5.4 and later versions.
1898
Neal Norwitze98ccf62006-03-23 05:39:47 +00001899- Bug #1115379: Compiling a Unicode string with an encoding declaration
1900 now gives a SyntaxError.
1901
Georg Brandlabd1ff82006-03-18 07:59:59 +00001902- Previously, Python code had no easy way to access the contents of a
1903 cell object. Now, a ``cell_contents`` attribute has been added
1904 (closes patch #1170323).
1905
Tim Peterscf79aac2006-03-16 01:14:46 +00001906- Patch #1123430: Python's small-object allocator now returns an arena to
1907 the system ``free()`` when all memory within an arena becomes unused
1908 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1909 freed. Some applications will see a drop in virtual memory size now,
1910 especially long-running applications that, from time to time, temporarily
1911 use a large number of small objects. Note that when Python returns an
1912 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001913 platform C library will in turn return that memory to the operating system.
1914 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001915 appears to be effective at least on Microsoft C and gcc-based systems.
1916 Thanks to Evan Jones for hard work and patience.
1917
Georg Brandl533ff6f2006-03-08 18:09:27 +00001918- Patch #1434038: property() now uses the getter's docstring if there is
1919 no "doc" argument given. This makes it possible to legitimately use
1920 property() as a decorator to produce a read-only property.
1921
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001922- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1923 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1924 of requiring an int or long in slicing and a few other contexts, enabling
1925 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1926
Neal Norwitz995acdf2006-03-07 05:01:00 +00001927- Fixed various bugs reported by Coverity's Prevent tool.
1928
Brett Cannonbf364092006-03-01 04:25:17 +00001929- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1930 new exception base class, BaseException, which has a new message attribute.
1931 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1932 Raising a string exception now raises a DeprecationWarning.
1933
Thomas Woutersfb609f42006-02-28 16:37:25 +00001934- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1935 explicitly relative, using 'from .module import name' to mean 'from the same
1936 package as this module is in. Imports without dots still default to the
1937 old relative-then-absolute, unless 'from __future__ import
1938 absolute_import' is used.
1939
Brett Cannona7446e32006-02-27 23:39:10 +00001940- Properly check if 'warnings' raises an exception (usually when a filter set
1941 to "error" is triggered) when raising a warning for raising string
1942 exceptions.
1943
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001944- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001945 The name was removed from Include/code.h.
1946
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001947- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001948
Guido van Rossum1968ad32006-02-25 22:38:04 +00001949- Patch 1433928:
1950 - The copy module now "copies" function objects (as atomic objects).
1951 - dict.__getitem__ now looks for a __missing__ hook before raising
1952 KeyError.
1953
Tim Peters84ef21c2006-02-28 20:39:06 +00001954- PEP 343: with statement implemented. Needs ``from __future__ import
1955 with_statement``. Use of 'with' as a variable will generate a warning.
1956 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001957 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001958 The following objects have __context__ methods:
1959 - The built-in file type.
1960 - The thread.LockType type.
1961 - The following types defined by the threading module:
1962 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1963 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001964
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001965- Fix the encodings package codec search function to only search
1966 inside its own package. Fixes problem reported in patch #1433198.
1967
1968 Note: Codec packages should implement and register their own
1969 codec search function. PEP 100 has the details.
1970
Tim Peters9ea89d22006-06-04 03:26:02 +00001971- PEP 353: Using ``Py_ssize_t`` as the index type.
1972
1973- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1974 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1975 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1976 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1977 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001978
Neal Norwitzfc76d632006-01-10 06:03:13 +00001979- Patch #1400181, fix unicode string formatting to not use the locale.
1980 This is how string objects work. u'%f' could use , instead of .
1981 for the decimal point. Now both strings and unicode always use periods.
1982
Neal Norwitz671b9e32006-01-09 07:07:12 +00001983- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1984 configure would break checking curses.h.
1985
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001986- Bug #959576: The pwd module is now builtin. This allows Python to be
1987 built on UNIX platforms without $HOME set.
1988
Neal Norwitzc10978f2005-12-19 06:07:16 +00001989- Bug #1072182, fix some potential problems if characters are signed.
1990
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001991- Bug #889500, fix line number on SyntaxWarning for global declarations.
1992
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001993- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1994
Neal Norwitze7214a12005-12-18 05:03:17 +00001995- Support for converting hex strings to floats no longer works.
1996 This was not portable. float('0x3') now raises a ValueError.
1997
Barry Warsaw2a38a862005-12-18 01:27:35 +00001998- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001999 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002000 is now displayed in interactive prompt banner.
2001
Georg Brandlfa166682005-12-17 21:45:17 +00002002- Implementation of PEP 341 - Unification of try/except and try/finally.
2003 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002004 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002005
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002006- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2007 now encodes backslash correctly.
2008
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002009- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2010
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002011- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002012 and long longs.
2013
Neal Norwitz67715f02005-11-09 06:59:35 +00002014- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002015 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002016 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002017
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002018- Replaced most Unicode charmap codecs with new ones using the
2019 new Unicode translate string feature in the builtin charmap
2020 codec; the codecs were created from the mapping tables available
2021 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2022 encodings now include a mapping for the Apple logo)
2023
Tim Peterse3547fd2005-12-16 23:13:57 +00002024- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002025
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002026- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002027
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002028- A new AST parser implementation was completed. The abstract
2029 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002030 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002031
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002032- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002033 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2034
Neal Norwitz708e51a2005-10-03 04:48:15 +00002035- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2036
Neal Norwitz11bd1192005-10-03 00:54:56 +00002037- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2038 Provide a warning when a directory is passed on the command line.
2039
Neal Norwitz40d37812005-10-02 01:48:49 +00002040- Fix segfault with invalid coding.
2041
2042- SF bug #772896: unknown encoding results in MemoryError.
2043
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002044- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002045 supported a __len__() method which evaluated to False when the iterator
2046 was empty.
2047
Guido van Rossum630db602005-09-20 18:49:54 +00002048- On 64-bit platforms, when __len__() returns a value that cannot be
2049 represented as a C int, raise OverflowError.

Skip Montanarof8948ca2005-09-19 03:54:46 +00002051- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002052 present).

Georg Brandl80bbf3f2005-09-14 19:38:29 +00002054- SF bug #893549: parsing keyword arguments was broken with a few format
2055 codes.
2056
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002057- Changes donated by Elemental Security to make it work on AIX 5.3
2058 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2059 bug #105470: test_pwd fails on 64bit system (Opteron).
2060
Guido van Rossum539c6622005-09-14 17:49:54 +00002061- Changes donated by Elemental Security to make it work on HP-UX 11 on
2062 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2063
Georg Brandl4550b8d2005-08-26 06:43:52 +00002064- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002065 (fixes bug #1119418).
2066
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002067- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2068
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002069- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2070 exceptions that cause a function to exit.
2071
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002072- The implementation of set() and frozenset() was revised to use its
2073 own internal data structure. Memory consumption is reduced by 1/3
2074 and there are modest speed-ups as well. The API is unchanged.
2075
Tim Petersde7990b2005-07-17 23:45:23 +00002076- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2077
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002078- SF bug #1229429: PyObject_CallMethod failed to decrement some
2079 reference counts in some error exit cases.
2080
Tim Petersecc6e6a2005-07-10 22:30:55 +00002081- SF bug #1185883: Python's small-object memory allocator took over
2082 a block managed by the platform C library whenever a realloc specified
2083 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002084 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002085 portable way to copy data from the C-managed block into Python's
2086 small-object space without risking a memory fault. Python's small-object
2087 realloc now leaves such blocks under the control of the platform C
2088 realloc.
2089
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002090- SF bug #1232517: An overflow error was not detected properly when
2091 attempting to convert a large float to an int in os.utime().
2092
Raymond Hettinger3296e692005-06-29 23:29:56 +00002093- SF bug #1224347: hex longs now print with lowercase letters just
2094 like their int counterparts.
2095
Michael W. Hudson188d4362005-06-20 16:52:57 +00002096- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2097 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2098 interpreter states; back out that fix and do a better job (see
2099 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2100 for a longer write-up of the problem).
2101
Michael W. Hudsondf888462005-06-03 14:41:55 +00002102- SF patch #1180995: marshal now uses a binary format by default when
2103 serializing floats.
2104
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002105- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2106 the routines that promise to produce IEEE 754 binary representations
2107 of floats now simply copy bytes around.
2108
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002109- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2110 278.
2111
Brett Cannonc3647ac2005-04-26 03:45:26 +00002112- patch #1109424: int, long, float, complex, and unicode now check for the
2113 proper magic slot for type conversions when subclassed. Previously the
2114 magic slot was ignored during conversion. Semantics now match the way
2115 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002116 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002117 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002118 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002119
Barry Warsawc8d907c2005-04-19 23:43:40 +00002120- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2121 NULL, now raise an AttributeError when attempting to set or delete the
2122 attribute. Previously a TypeError was raised, but this was inconsistent
2123 with the equivalent pure-Python implementation.
2124
Michael W. Hudson774479c2005-04-18 08:46:17 +00002125- It is now safe to call PyGILState_Release() before
2126 PyEval_InitThreads() (note that if there is reason to believe there
2127 are multiple threads around you still must call PyEval_InitThreads()
2128 before using the Python API; this fix is for extension modules that
2129 have no way of knowing if Python is multi-threaded yet).
2130
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002131- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2132 disabled caused a crash.
2133
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002134- Bug #1165306: instancemethod_new allowed the creation of a method
2135 with im_class == im_self == NULL, which caused a crash when called.
2136
Tim Petersecc6e6a2005-07-10 22:30:55 +00002137- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002138 fixes the crash seen in bug #1165761
2139
Raymond Hettinger96229b12005-03-11 06:49:40 +00002140- Added two new builtins, any() and all().
2141
Brett Cannon409d8f22005-03-05 06:47:57 +00002142- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002143 (e.g., ``class C(): pass`` is no longer a syntax error).
2144 Patch #1176012 added support to the 'parser' module and 'compiler' package
2145 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002146
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002147- Patch #1115086: Support PY_LONGLONG in structmember.
2148
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002149- Bug #1155938: new style classes did not check that __init__() was
2150 returning None.
2151
Tim Petersecc6e6a2005-07-10 22:30:55 +00002152- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002153 ('\') with a specific error message.
2154
Martin v. Löwisff232d72005-03-03 09:24:38 +00002155- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2156
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002157- Bug #1124295: the __name__ attribute of file objects was
2158 inadvertently made inaccessible in restricted mode.
2159
Tim Petersecc6e6a2005-07-10 22:30:55 +00002160- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002161 an ferror() call.
2162
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002163- min() and max() now support key= arguments with the same meaning as in
2164 list.sort().
2165
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002166- The peephole optimizer now performs simple constant folding in expressions:
2167 (2+3) --> (5).
2168
Raymond Hettingera422c342005-01-11 03:03:27 +00002169- set and frozenset objects can now be marshalled. SF #1098985.
2170
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002171- Bug #1077106: Poor argument checking could cause memory corruption
2172 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002173
Jeremy Hyltonab630502005-02-04 18:44:06 +00002174- The parser did not complain about future statements in illegal
2175 positions. It once again reports a syntax error if a future
2176 statement occurs after anything other than a doc string.
2177
Neil Schemenauercf52c072005-08-12 17:34:58 +00002178- Change the %s format specifier for str objects so that it returns a
2179 unicode instance if the argument is not an instance of basestring and
2180 calling __str__ on the argument returns a unicode instance.
2181
Tim Petersf4e69282006-02-27 17:15:31 +00002182- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2183 current thread state when the auto-GIL-state machinery knows about
2184 it (since the thread state is being deleted, continuing to remember it
2185 can't help, but can hurt if another thread happens to get created with
2186 the same thread id).
2187

Neal Norwitz10be10c2006-03-16 06:50:13 +00002204 util, whatsound, whrandom, zmod
2205
2206- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2207
2208- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002209 is deprecated. The undocumented re.engine variable no longer exists.
2210
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002211- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2212 SS2 (single-shift 2) escape sequences correctly.
2213
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002214- The unicodedata module was updated to the 4.1 version of the Unicode
2215 database. The 3.2 version is still available as unicodedata.db_3_2_0
2216 for applications that require this specific version (such as IDNA).
2217
Neal Norwitzb62c4332006-03-04 18:35:47 +00002218- The timing module is no longer built by default. It was deprecated
2219 in PEP 4 in Python 2.0 or earlier.
2220
Guido van Rossum1968ad32006-02-25 22:38:04 +00002221- Patch 1433928: Added a new type, defaultdict, to the collections module.
2222 This uses the new __missing__ hook behavior added to dict (see above).
2223
Georg Brandldbd83392006-02-20 09:42:33 +00002224- Bug #854823: socketmodule now builds on Sun platforms even when
2225 INET_ADDRSTRLEN is not defined.
2226
Georg Brandlf4f44152006-02-18 22:29:33 +00002227- Patch #1393157: os.startfile() now has an optional argument to specify
2228 a "command verb" to invoke on the file.
2229
Neal Norwitz082b2df2006-02-07 07:04:46 +00002230- Bug #876637, prevent stack corruption when socket descriptor

2232
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002233- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2234 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2235 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2238 than the system default domain.
2239
Martin v. Löwis14694662006-02-03 12:54:16 +00002240- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2241 are reported, the limit on path name lengths is removed, and stat reports
2242 WindowsError now (instead of OSError).
2243
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002244- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2319 the request code argument, which results in more C-like behaviour
2320 for large or negative values.
2321
Tim Petersecc6e6a2005-07-10 22:30:55 +00002322- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2331 available on the platform.
2332
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002333- Bug #1166660: The readline module could segfault if hook functions
2334 were set in a different thread than that which called readline.
2335
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00002336- collections.deque objects now support a remove() method.
2337
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002338- operator.itemgetter() and operator.attrgetter() now support retrieving
2339 multiple fields. This provides direct support for sorting on multiple
2340 keys (primary, secondary, etc).
2341
Martin v. Löwisb60ae992005-03-08 09:10:29 +00002342- os.access now supports Unicode path names on non-Win32 systems.

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002362- the cPickle module no longer accepts the deprecated None option in the
2363 args tuple returned by __reduce__().
2364
Raymond Hettingerb2594052004-12-05 09:25:51 +00002365- itertools.islice() now accepts None for the start and step arguments.
2366 This allows islice() to work more readily with slices:
2367 islice(s.start, s.stop, s.step)
2368
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002369- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002378- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2379 been renamed to have only a single underscore prefix. This was done to
2380 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002381
Nick Coghlan43832302006-04-23 17:04:07 +00002382- PEP 338: new module runpy defines a run_module function to support
2383 executing modules which provide access to source code or a code object
2384 via the PEP 302 import mechanisms.
2385
Anthony Baxter93f5b932006-04-03 08:05:07 +00002386- The email module's parsedate_tz function now sets the daylight savings
2387 flag to -1 (unknown) since it can't tell from the date whether it should

2394 in attribute values.
2395
Anthony Baxterc51ee692006-04-01 00:57:31 +00002396- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002397 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002398 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002399 module will not be built.
2400
Tim Petersc17976e2006-04-01 00:26:53 +00002401- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2402 aren't officially supported here, and trying to use them will probably
2403 raise an exception some day. But dicts have been allowed, and "mostly
2404 worked", so support for them won't go away without warning.
2405
Georg Brandl338ef7d2006-03-31 18:42:16 +00002406- Bug #1445068: getpass.getpass() can now be given an explicit stream
2407 argument to specify where to write the prompt.
2408
Georg Brandl22ec80b2006-03-31 18:25:44 +00002409- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2410 that have __private names in their __slots__.
2411

2416
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002417- Queue.Queue objects now support .task_done() and .join() methods
2418 to make it easier to monitor when daemon threads have completed
2419 processing all enqueued tasks. Patch #1455676.
2420
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002421- popen2.Popen objects now preserve the command in a .cmd attribute.
2422

2424
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002425- email 4.0 package now integrated. This is largely the same as the email 3.0
2426 package that was included in Python 2.3, except that PEP 8 module names are
2427 now used (e.g. mail.message instead of email.Message). The MIME classes
2428 have been moved to a subpackage (e.g. email.mime.text instead of
2429 email.MIMEText). The old names are still supported for now. Several
2430 deprecated Message methods have been removed and lots of bugs have been
2431 fixed. More details can be found in the email package documentation.
2432
Walter Dörwald40108c92006-03-27 08:15:44 +00002433- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2434 (a subclass of tuple) that provides incremental decoders and encoders
2435 (a way to use stateful codecs without the stream API). Python functions
2436 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2437 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2438 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002439
Walter Dörwald067db482006-03-15 22:17:27 +00002440- Patch #1359365: Calling next() on a closed StringIO.String object raises
2441 a ValueError instead of a StopIteration now (like file and cString.String do).
2442 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2443 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002444
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002445- A regrtest option -w was added to re-run failed tests in verbose mode.

2455
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002456- PEP 343: new module contextlib.py defines decorator @contextmanager
2457 and helpful context managers nested() and closing().
2458
Martin v. Löwis415ed932006-02-27 19:56:30 +00002459- The compiler package now supports future imports after the module docstring.
2460

2463
Georg Brandlc98eeed2006-02-19 14:57:47 +00002464- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002493 specifications, raises IOErrors when proxies for unsupported protocols
2494 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002517 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2518 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2519 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2520 Ronald L. Rivest offered this advice for Python:
2521
2522 "The consensus of researchers in this area (at least as
2523 expressed at the NIST Hash Function Workshop 10/31/05),
2524 is that SHA-256 is a good choice for the time being, but
2525 that research should continue, and other alternatives may
2526 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002527
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002528- Added a subset of Fredrik Lundh's ElementTree package. Available

2581 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002582 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002583

Guido van Rossum755149f2005-07-27 00:00:44 +00002591- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2592 __hasattr__ and __delattr__ methods on class Tk that were breaking
2593 Tkdnd.
2594
Georg Brandl5dbda752005-07-17 20:27:41 +00002595- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2596 docstrings to either "article number" or "message id".
2597
Georg Brandla4a8b822005-07-15 09:13:21 +00002598- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2599 parameter, but uses the usual "kwargs=None".
2600
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002601- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002602 Patch #1209527 (Contributed by Connelly).
2603
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002604- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2605 to W3C name (404 -> 'Not Found'). RFE #1216944.
2606
Georg Brandl9e43acf2005-07-04 17:16:07 +00002607- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2608 as this can cause problems with apps closing all file descriptors.
2609
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002610- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002611 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002612
Georg Brandl2f210b62005-06-26 22:09:06 +00002613- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2614
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002615- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2616 error messages.
2617
Georg Brandl379f99d2005-06-26 21:09:38 +00002618- Bug #1108948: Cookie.py produced invalid JavaScript code.
2619
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002620- The tokenize module now detects and reports indentation errors.
2621 Bug #1224621.
2622
Raymond Hettinger68c04532005-06-10 11:05:19 +00002623- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002624 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002625 the generate_tokens() function now accepts a callable argument that
2626 terminates by raising StopIteration.
2627
Georg Brandl9166e1a2005-06-04 09:20:03 +00002628- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2629
Georg Brandl268e61c2005-06-03 14:28:50 +00002630- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2631 component of the path.
2632
Skip Montanaro174dd222005-05-14 20:54:16 +00002633- Patch #1120353: The xmlrpclib module provides better, more transparent,
2634 support for datetime.{datetime,date,time} objects. With use_datetime set
2635 to True, applications shouldn't have to fiddle with the DateTime wrapper
2636 class at all.
2637
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002638- distutils.commands.upload was added to support uploading distribution
2639 files to PyPI.
2640
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002641- distutils.commands.register now encodes the data as UTF-8 before posting
2642 them to PyPI.
2643
Raymond Hettinger267b8682005-03-27 10:47:39 +00002644- decimal operator and comparison methods now return NotImplemented
2645 instead of raising a TypeError when interacting with other types. This
2646 allows other classes to implement __radd__ style methods and have them
2647 work as expected.
2648
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002649- Bug #1163325: Decimal infinities failed to hash. Attempting to
2650 hash a NaN raised an InvalidOperation instead of a TypeError.
2651
Tim Petersecc6e6a2005-07-10 22:30:55 +00002652- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002653 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2654

2686
Guido van Rossumd0641422005-02-03 15:01:24 +00002687- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2688 disables recursive traversal through instance attributes, which can
2689 be exploited in various ways.
2690
Tim Peterse3547fd2005-12-16 23:13:57 +00002691- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002692 flags on the HTTP listening socket.
2693
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002694- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2695 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2696
Fred Drakefbdeaad2006-07-29 16:56:15 +00002697- Patches #893642, #1039083: add allow_none, encoding arguments to
2698 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002699
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002700- Bug #1110478: Revert os.environ.update to do putenv again.
2701
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002702- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2703
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002704- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2705
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002706- Enhancements to the csv module:
2707
2708 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002709 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002710 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002711 + Dialect parameter parsing has been re-implemented to improve error
2712 reporting.
2713 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2714 dictates.
2715 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002716 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002717 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002718 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2719 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002720 + reader now allows \r characters to be quoted (previously it only allowed
2721 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002722 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002723 + Dialect classes passed to the module are no longer instantiated by
2724 the module before being parsed (the former validation scheme required
2725 this, but the mechanism was unreliable).
2726 + The dialect registry now contains instances of the internal
2727 C-coded dialect type, rather than references to python objects.
2728 + the internal c-coded dialect type is now immutable.
2729 + register_dialect now accepts the same keyword dialect specifications
2730 as the reader and writer, allowing the user to register dialects
2731 without first creating a dialect class.
2732 + a configurable limit to the size of parsed fields has been added -
2733 previously, an unmatched quote character could result in the entire
2734 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002735 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002736 the parser field size limit (returning the former limit). The initial
2737 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002738 + A line_num attribute has been added to the reader object, which tracks
2739 the number of lines read from the source iterator. This is not
2740 the same as the number of records returned, as records can span
2741 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002742 + reader and writer objects were not being registered with the cyclic-GC.
2743 This has been fixed.
2744
Brett Cannone6539c42005-01-08 02:43:53 +00002745- _DummyThread objects in the threading module now delete self.__block that is
2746 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2747 lock primitives tend to be limited in number and thus should not be wasted on
2748 a _DummyThread object. Fixes bug #1089632.
2749
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002750- The imghdr module now detects Exif files.
2751
Raymond Hettinger6065d322004-12-20 23:51:53 +00002752- StringIO.truncate() now correctly adjusts the size attribute.
2753 (Bug #951915).
2754
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002755- locale.py now uses an updated locale alias table (built using
2756 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2757 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002758 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002759
Raymond Hettinger3557f422004-12-07 12:02:02 +00002760- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2761
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002762- the pickle module no longer accepts the deprecated None option in the
2763 args tuple returned by __reduce__().
2764
Brett Cannon84667c02004-12-07 03:25:18 +00002765- optparse now optionally imports gettext. This allows its use in setup.py.
2766
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002767- the pickle module no longer uses the deprecated bin parameter.
2768
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002769- the shelve module no longer uses the deprecated binary parameter.
2770
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002771- the pstats module no longer uses the deprecated ignore() method.
2772
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002773- the filecmp module no longer uses the deprecated use_statcache argument.
2774
Raymond Hettinger664347b2004-12-04 21:21:53 +00002775- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2776 extended or overridden by subclasses. Formerly, the subclassed method would
2777 be ignored by the rest of the module. (Bug #1078905).
2778
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002779- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002780 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002781
Walter Dörwald36733692004-12-22 12:50:50 +00002782- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2783 once when a size argument is given. This prevents a buffer overflow in the
2784 tokenizer with very long source lines.
2785
Barry Warsaw538561e2006-01-01 21:48:54 +00002786- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2787 immediately after creating the object, without any intervening
2788 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002789
Skip Montanaro05885812005-01-16 20:48:27 +00002790- The reconvert.quote function can now emit triple-quoted strings. The
2791 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002792
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002793- ``UserString.MutableString`` now supports negative indices in
2794 ``__setitem__`` and ``__delitem__``
2795
Greg Ward40407942005-03-05 02:53:17 +00002796- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2797 correctly.
2798
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002799- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2800 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2801 character even if the user has passed a size parameter to get a proper
2802 line ending. Remove the special handling of a "\r\n" that has been split
2803 between two lines.
2804
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002805- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2806 about illegal code points. The codec now supports PEP 293 style error
2807 handlers.
2808
Walter Dörwald78a78b02005-09-01 12:04:29 +00002809- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002810 from the input stream, so that the output is a byte string in the correct
2811 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002812
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002813- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2814 considering it exactly like a '*'.
2815
Walter Dörwald007f8df2005-10-09 19:42:27 +00002816- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2817 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002818
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002819- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2820
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002821- Patch #1413711: Certain patterns of differences were making difflib
2822 touch the recursion limit.
2823
Walter Dörwald58917a62006-03-31 15:26:22 +00002824- Bug #947906: An object oriented interface has been added to the calendar
2825 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002826 called as a script (e.g. via ``python -mcalendar``). Localized month and
2827 weekday names can be ouput (even if an exotic encoding is used) using
2828 special classes that use unicode.

Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002840- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2841
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002842- Patch #881820: look for openpty and forkpty also in libbsd.
2843
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002844- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2845 The zlib module is now builtin on Windows.
2846
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002847- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2848
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002849- Bug #1189330: configure did not correctly determine the necessary
2850 value of LINKCC if python was built with GCC 4.0.
2851
Trent Mick8321b422005-07-26 02:29:21 +00002852- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2853 vulnerability in zlib 1.2.1 and 1.2.2.
2854
Brett Cannon08cd5982005-04-24 22:26:38 +00002855- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2856 flags that change binary compatibility. Changes were also made to
2857 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002858 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002859
Bob Ippolitoed233462005-03-29 13:47:59 +00002860- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2861 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2862 no longer exists). This configure patch makes things right.
2863
Martin v. Löwise2713be2005-03-08 15:03:08 +00002864- Bug #1158607: Build with --disable-unicode again.
2865
Brett Cannon46d96232005-02-16 00:07:19 +00002866- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2867 defined. Discovered as a result of not being able to build on OS X.
2868
Brett Cannon516592f2004-12-07 00:42:59 +00002869- setup.py now uses the directories specified in LDFLAGS using the -L option
2870 and in CPPFLAGS using the -I option for adding library and include
2871 directories, respectively, for compiling extension modules against. This has
2872 led to the core being compiled using the values in CPPFLAGS. It also removes
2873 the need for the special-casing of both DarwinPorts and Fink for darwin since
2874 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2875 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2876 Fink, ``-I/opt/local/include`` for DarwinPorts).
2877
Brett Cannon43802422005-02-10 20:48:03 +00002878- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2879 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2880 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2881 Closes bug #1096244. Thanks Gregory Bond.

2884-----
2885
Tim Petersc9d78aa2006-03-26 23:27:58 +00002886- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2887 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2888 is obtained via the ``PyObject_`` family, it must be released via the
2889 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2890 always been officially true, but when Python's small-object allocator was
2891 introduced, an attempt was made to cater to a few extension modules
2892 discovered at the time that obtained memory via ``PyObject_New`` but
2893 released it via ``PyMem_DEL``. It's years later, and if such code still
2894 exists it will fail now (probably with segfaults, but calling wrong
2895 low-level memory management functions can yield many symptoms).
2896
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002897- Added a C API for set and frozenset objects.
2898
Raymond Hettinger66517482004-12-03 11:45:13 +00002899- Removed PyRange_New().
2900
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002901- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2902 mapping argument now. This string is used as a mapping table. Byte values
2903 greater than the length of the string and 0xFFFE are treated as undefined
2904 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002911
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002912- Patch #1276356: New resource "urlfetch" is implemented. This enables
2913 even impatient people to run tests that require remote files.
