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
Raymond Hettinger13936692007-04-11 18:40:58 +000015- Request #1191699: Slices can now be pickled.
16
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000017- Request #1193128: str.translate() now allows a None argument for
18 translations that only remove characters without re-mapping the
19 remaining characters.
20
Georg Brandl5cb76c12007-03-21 09:00:39 +000021- Patch #1682205: a TypeError while unpacking an iterable is no longer
22 masked by a generic one with the message "unpack non-sequence".
23
Neal Norwitzaa754b72007-03-21 06:39:48 +000024- Remove unused file Python/fmod.c.
25
Guido van Rossum143b5642007-03-23 04:58:42 +000026- Bug #1683368: The object.__init__() and object.__new__() methods are
27 now stricter in rejecting excess arguments. The only time when
28 either allows excess arguments is when it is not overridden and the
29 other one is. For backwards compatibility, when both are
30 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000031 warning later). Also, type.__init__() insists on the same signature
32 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000033
Georg Brandl2b869942007-03-17 16:08:45 +000034- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
35 to complex using its __complex__() method before falling back to the
36 __float__() method. Therefore, the functions in the cmath module now
37 can operate on objects that define a __complex__() method.
38
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000039- Patch #1623563: allow __class__ assignment for classes with __slots__.
40 The old and the new class are still required to have the same slot names.
41
Collin Winter77c67bd2007-03-16 04:11:30 +000042- Patch #1642547: Fix an error/crash when encountering syntax errors in
43 complex if statements.
44
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000045- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
46 is called with an object that is faking its type.
47
Žiga Seilnacht71436f02007-03-14 12:24:09 +000048- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
49 name.
50
Georg Brandl5240d742007-03-13 20:46:32 +000051- Patch #1444529: the builtin compile() now accepts keyword arguments.
52
Georg Brandl7b9c5552007-03-12 14:30:05 +000053- Bug #1678647: write a newline after printing an exception in any
54 case, even when converting the value to a string failed.
55
Georg Brandl871f1bc2007-03-12 13:17:36 +000056- The dir() function has been extended to call the __dir__() method on
57 its argument, if it exists. If not, it will work like before. This allows
58 customizing the output of dir() in the presence of a __getattr__().
59
Collin Winter276887b2007-03-12 16:11:39 +000060- Patch #922167: Python no longer segfaults when faced with infinitely
61 self-recursive reload() calls (as reported by bug #742342).
62
Žiga Seilnacht89032082007-03-11 15:54:54 +000063- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
64
Collin Wintere38051d2007-03-09 20:33:07 +000065- Patch #1491866: change the complex() constructor to allow parthensized
66 forms. This means complex(repr(x)) now works instead of raising a
67 ValueError.
68
Georg Brandlaa2321b2007-03-07 00:40:28 +000069- Patch #703779: unset __file__ in __main__ after running a file. This
70 makes the filenames the warning module prints much more sensible when
71 a PYTHONSTARTUP file is used.
72
Georg Brandl49aafc92007-03-07 00:34:46 +000073- Variant of patch #697613: don't exit the interpreter on a SystemExit
74 exception if the -i command line option or PYTHONINSPECT environment
75 variable is given, but break into the interactive interpreter just like
76 on other exceptions or normal program exit.
77
Georg Brandl00cd8182007-03-06 18:41:12 +000078- Patch #1638879: don't accept strings with embedded NUL bytes in long().
79
Georg Brandl098cd692007-03-06 12:17:50 +000080- Bug #1674503: close the file opened by execfile() in an error condition.
81
Georg Brandl0fca97a2007-03-05 22:28:08 +000082- Patch #1674228: when assigning a slice (old-style), check for the
83 sq_ass_slice instead of the sq_slice slot.
84
Neal Norwitz88516a62007-02-26 22:41:45 +000085- When printing an unraisable error, don't print exceptions. before the name.
86 This duplicates the behavior whening normally printing exceptions.
87
Martin v. Löwisfd963262007-02-09 12:19:32 +000088- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
89
Brett Cannon129bd522007-01-30 21:34:36 +000090- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
91 catch a string exception raises DeprecationWarning.
92
Brett Cannonf5bee302007-01-23 23:21:22 +000093- Bug #1377858: Fix the segfaulting of the interpreter when an object created
94 a weakref on itself during a __del__ call for new-style classes (classic
95 classes still have the bug).
96
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000097- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
98 frame's thread state.
99

103
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000104- Prevent seg fault on shutdown which could occur if an object
105 raised a warning.
106
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000107- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
108 to avoid relying on atexit.
109
Raymond Hettinger94547f72006-12-20 06:42:06 +0000110- Bug #1590891: random.randrange don't return correct value for big number
111
Georg Brandl283a1352006-11-19 08:48:30 +0000112- Patch #1586791: Better exception messages for some operations on strings,

120
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000121- Bug #1576657: when setting a KeyError for a tuple key, make sure that
122 the tuple isn't used as the "exception arguments tuple".
123
Neal Norwitz21997af2006-10-28 21:19:07 +0000124- Bug #1565514, SystemError not raised on too many nested blocks.
125
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000126- Bug #1576174: WindowsError now displays the windows error code
127 again, no longer the posix error code.
128
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000129- Patch #1549049: Support long values in structmember, issue warnings
130 if the assigned value for structmember fields gets truncated.
131
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000132- Update the peephole optimizer to remove more dead code (jumps after returns)
133 and inline unconditional jumps to returns.
134
Georg Brandl2c1375c2006-10-12 11:27:59 +0000135- Bug #1545497: when given an explicit base, int() did ignore NULs
136 embedded in the string to convert.
137
Georg Brandl846f73a2006-10-08 07:11:54 +0000138- Bug #1569998: break inside a try statement (outside a loop) is now
139 recognized and rejected.
140
Armin Rigo7ccbca92006-10-04 12:17:45 +0000141- list.pop(x) accepts any object x following the __index__ protocol.
142
143- Fix some leftovers from the conversion from int to Py_ssize_t
144 (relevant to strings and sequences of more than 2**31 items).
145
146- A number of places, including integer negation and absolute value,
147 were fixed to not rely on undefined behaviour of the C compiler
148 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000149
Georg Brandl3267d282006-09-30 09:03:42 +0000150- Bug #1566800: make sure that EnvironmentError can be called with any

166
Brett Cannon9adeab72006-09-20 18:34:28 +0000167- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
168 allows calling unicode() on exceptions classes directly to succeed.
169
Georg Brandlec6c2df2006-09-11 09:38:35 +0000170- Make _PyGILState_NoteThreadState() static, it was not used anywhere

178 imports (if not in package and if beyond toplevel package).
179
Tim Petersc10c9d02006-09-05 02:18:09 +0000180- Overflow checking code in integer division ran afoul of new gcc
181 optimizations. Changed to be more standard-conforming.

188 head is the original string if sep was not found.
189
Neal Norwitzdac090d2006-09-05 03:53:08 +0000190- Bug #1520864: unpacking singleton tuples in list comprehensions and
191 generator expressions (x for x, in ... ) works again. Fixing this problem
192 required changing the .pyc magic number. This means that .pyc files
193 generated before 2.5c2 will be regenerated.
194

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000199- Add new requirements for metaclasses. 1) If type or a subclass of type
200 occurs in __bases__, it must occur before any non-type bases, e.g.
201 before regular classes. 2) If you assign to __bases__, you may not
202 change the metaclass. Many more illegal assignments to __bases__
203 are now checked and raise TypeErrors. This changed fixed at least
204 one known crash.
205

237 trying Mozilla variants.
238
Collin Winter6f187742007-03-16 22:16:08 +0000239- Patch #1339796: add a relpath() function to os.path.

324
Georg Brandl9caadf82007-03-08 18:37:31 +0000325- unittest now verifies more of its assumptions. In particular, TestCase
326 and TestSuite subclasses (not instances) are no longer accepted in
327 TestSuite.addTest(). This should cause no incompatibility since it

Guido van Rossumc69ac252006-08-10 18:09:25 +0000842What's New in Python 2.5 release candidate 1?
843=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000844
Anthony Baxterb4096662006-08-16 03:42:26 +0000845*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000846
847Core and builtins
848-----------------
849
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000850- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000851 compared equal or unequal to a string and a UnicodeDecodeError
852 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000853
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000854 Instead, the equal (==) and unequal (!=) comparison operators will
855 now issue a UnicodeWarning and interpret the two objects as
856 unequal. The UnicodeWarning can be filtered as desired using
857 the warning framework, e.g. silenced completely, turned into an
858 exception, logged, etc.
859
860 Note that compare operators other than equal and unequal will still
861 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000862
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000863- Fix segfault when doing string formatting on subclasses of long.
864
865- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
866 with new-style classes.
867
868- Fix bug related to __len__ functions returning negative values with
869 classic classes.
870
871- Patch #1538606, Fix __index__() clipping. There were some problems
872 discovered with the API and how integers that didn't fit into Py_ssize_t
873 were handled. This patch attempts to provide enough alternatives
874 to effectively use __index__.
875
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000876- Bug #1536021: __hash__ may now return long int; the final hash
877 value is obtained by invoking hash on the long int.
878
Thomas Hellerab1049c2006-08-08 17:37:00 +0000879- Bug #1536786: buffer comparison could emit a RuntimeWarning.
880
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000881- Bug #1535165: fixed a segfault in input() and raw_input() when

883
Thomas Heller74d36f02006-08-04 18:17:40 +0000884- On Windows, the PyErr_Warn function is now exported from
885 the Python dll again.
886
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000887- Bug #1191458: tracing over for loops now produces a line event
888 on each iteration. Fixing this problem required changing the .pyc
889 magic number. This means that .pyc files generated before 2.5c1
890 will be regenerated.
891
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000892- Bug #1333982: string/number constants were inappropriately stored
893 in the byte code and co_consts even if they were not used, ie
894 immediately popped off the stack.
895
Georg Brandle9462c72006-08-04 18:03:37 +0000896- Fixed a reference-counting problem in property().

900-------
901
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000902- Fix a bug in the ``compiler`` package that caused invalid code to be
903 generated for generator expressions.
904
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000905- The distutils version has been changed to 2.5.0. The change to
906 keep it programmatically in sync with the Python version running
907 the code (introduced in 2.5b3) has been reverted. It will continue
908 to be maintained manually as static string literal.
909
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000910- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000911 and this cannot be converted to the required C type, an exception is
912 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000913 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000914
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000915- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000916 an exception.
917
Tim Petersc10c9d02006-09-05 02:18:09 +0000918- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000919 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000920 workarounds for clocks with low resolution, to stop the code yielding
921 duplicate UUIDs.
922
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000923- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
924 before raising SystemExit, allowing IDLE to honor quit() and exit().
925
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000926- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
927
Georg Brandl7a1af772006-08-14 21:55:28 +0000928- Patch #1536071: trace.py should now find the full module name of a
929 file correctly even on Windows.
930
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000931- logging's atexit hook now runs even if the rest of the module has
932 already been cleaned up.
933
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000934- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000935
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000936- Bug #1531405, format_exception no longer raises an exception if
937 str(exception) raised an exception.
938
Neil Schemenauer06ded092006-08-04 16:20:30 +0000939- Fix a bug in the ``compiler`` package that caused invalid code to be
940 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000948- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
949 raises the correct exceptions.
950
Thomas Heller1ce433e2006-08-14 16:20:04 +0000951- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
952 '-no-stack-protector' compiler flag for OpenBSD has been removed.
953
Thomas Heller86720042006-08-14 11:17:48 +0000954- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
955 uses the _as_parameter_ attribute when objects are passed to foreign
956 function calls. The ctypes version number was changed to 1.0.1.
957
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000958- Bug #1530559, struct.pack raises TypeError where it used to convert.
959 Passing float arguments to struct.pack when integers are expected
960 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000986- Bug #1535502, build _hashlib on Windows, and use masm assembler
987 code in OpenSSL.
988
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000989- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

998
Tim Peters4643c2f2006-08-10 22:45:34 +0000999- Bug #1069160. Internal correctness changes were made to
1000 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1001 the documentation was changed to state that the return value
1002 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +00001007
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001008*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001009
1010Core and builtins
1011-----------------
1012
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001013- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001014 returned a long (see PEP 353).
1015
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001016- Bug #1515471: string.replace() accepts character buffers again.
1017
Neal Norwitz07aadb12006-07-30 06:55:48 +00001018- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1019 This provides the proper warning for struct.pack().
1020 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1021
Neal Norwitz0d62a062006-07-30 06:53:31 +00001022- Patch #1531113: Fix augmented assignment with yield expressions.
1023 Also fix a SystemError when trying to assign to yield expressions.
1024
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001025- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1026 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1027 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1028 excessive filesystem operations during imports.
1029
Tim Petersbc24eee2006-07-27 01:14:53 +00001030- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1031 operations on signed longs that are formally undefined by C.
1032 Unfortunately, at least one compiler now cares about that, so complicated
1033 the code to make that compiler happy again.
1034
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001035- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1036
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001037- Patch #1232023: Stop including current directory in search
1038 path on Windows.
1039
Neal Norwitze1fdb322006-07-21 05:32:28 +00001040- Fix some potential crashes found with failmalloc.
1041
Neal Norwitze7563102006-07-17 01:00:16 +00001042- Fix warnings reported by Klocwork's static analysis tool.
1043
Neal Norwitz84be93b2006-07-16 01:50:38 +00001044- Bug #1512814, Fix incorrect lineno's when code within a function
1045 had more than 255 blank lines.
1046
Georg Brandl9dceedb2006-07-12 15:31:17 +00001047- Patch #1521179: Python now accepts the standard options ``--help`` and
1048 ``--version`` as well as ``/?`` on Windows.
1049
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001050- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001051 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001052 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001053
Tim Peters112aad32006-07-19 00:03:19 +00001054- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001055 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001056 new ``sys._current_frames()`` returns a dictionary with one entry,
1057 mapping the faux "thread id" 0 to the current frame.
1058
Ronald Oussoren3075e162006-07-25 20:28:55 +00001059- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001060
Ronald Oussoren3075e162006-07-25 20:28:55 +00001061
Neal Norwitza1f10902006-07-12 07:28:29 +00001062Library
1063-------
1064
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001065- Correction of patch #1455898: In the mbcs decoder, set final=False
1066 for stream decoder, but final=True for the decode function.
1067
Georg Brandl07fec3a2006-08-01 18:49:24 +00001068- os.urandom no longer masks unrelated exceptions like SystemExit or
1069 KeyboardInterrupt.
1070
Tim Peters4643c2f2006-08-10 22:45:34 +00001071- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001072 shutil.copytree on Windows
1073
Georg Brandle34ac7c2006-07-30 11:07:23 +00001074- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1075 refers to file descriptors, not file objects.
1076
Tim Petersc10c9d02006-09-05 02:18:09 +00001077- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001078 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001079 #1513611, and probably others.
1080
Georg Brandledd9b0d2006-07-29 09:33:26 +00001081- Bug #1441397: The compiler module now recognizes module and function
1082 docstrings correctly as it did in Python 2.4.
1083
Tim Peters6f681472006-07-27 23:44:37 +00001084- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1085 lost that tests are sorted by name before being run. This rarely
1086 matters for well-written tests, but can create baffling symptoms if
1087 side effects from one test to the next affect outcomes. ``DocTestFinder``
1088 has been changed to sort the list of tests it returns.
1089
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001090- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001091 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001092
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001093- Bug #978833: Really close underlying socket in _socketobject.close.
1094
Georg Brandl8c036cc2006-08-20 13:15:39 +00001095- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1096 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001097
Georg Brandlcf0c1722006-07-26 07:23:32 +00001098- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1099 to recursive calls and call it with the failing package name.
1100
Martin v. Löwis0b483032006-07-25 09:53:12 +00001101- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1102
Georg Brandlc13c34c2006-07-24 14:09:56 +00001103- Patch #1515343: Fix printing of deprecated string exceptions with a
1104 value in the traceback module.
1105
Greg Ward48fae7a2006-07-23 16:05:51 +00001106- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1107
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001108- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1109
Brett Cannoncaebe222006-07-18 04:41:36 +00001110- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1111 argument tuple. For arguments where zero is illegal, the value is forced to
1112 the minimum value that is correct. This is to support an undocumented but
1113 common way people used to fill in inconsequential information in the time
1114 tuple pre-2.4.
1115
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001116- Patch #1220874: Update the binhex module for Mach-O.
1117
Barry Warsawb110bad2006-07-21 14:51:07 +00001118- The email package has improved RFC 2231 support, specifically for
1119 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1120 (name*0=<blah>) parameter continuations. This may change the types of
1121 values returned from email.message.Message.get_param() and friends.
1122 Specifically in some cases where non-encoded continuations were used,
1123 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1124 will just return the string (since non-encoded continuations don't have
1125 charset and language parts).
1126
1127 Also, whereas % values were decoded in all parameter continuations, they are
1128 now only decoded in encoded parameter parts.
1129
Ronald Oussoren3075e162006-07-25 20:28:55 +00001130- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1131
1132- Bug #1517996: IDLE now longer shows the default Tk menu when a
1133 path browser, class browser or debugger is the frontmost window on MacOS X
1134
Barry Warsaw00decd72006-07-27 23:43:15 +00001135- Patch #1520294: Support for getset and member descriptors in types.py,
1136 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1137 of an object against these built-in types and more importantly, for getting
1138 their docstrings printed in the interactive interpreter's help() function.

1142-----------------
1143
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001144- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1145 a socket operation on a socket with a timeout, the exception will be
1146 caught correctly. Previously, the exception was not caught.
1147
Thomas Heller1393d6a2006-07-28 21:43:20 +00001148- Patch #1529514: The _ctypes extension is now compiled on more
1149 openbsd target platforms.
1150
Tim Peters9cab5932006-07-28 00:30:00 +00001151- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1152 a memory leak, affecting pickles and deep copies.
1153
Tim Petersbc24eee2006-07-27 01:14:53 +00001154- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001155 Paul Eggert.
1156
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001157- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1158
Thomas Hellerce049a02006-07-14 17:51:14 +00001159- Patch #1521817: Index range checking on ctypes arrays containing
1160 exactly one element enabled again. This allows iterating over these
1161 arrays, without the need to check the array size before.
1162
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001163- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001164 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001165 /dev/null in certain cases; this is now fixed.
1166
Thomas Heller47d7a062006-07-12 08:43:47 +00001167- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1168 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001169
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001170- Because of a misspelled preprocessor symbol, ctypes was always
1171 compiled without thread support; this is now fixed.
1172
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001173- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1174 methods now allow their database parameter to be None as the
1175 sleepycat API allows.
1176
Matt Flemingec926502006-07-28 11:27:27 +00001177- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1178 bluetooth API compared with Linux and FreeBSD.
1179
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001180Tests
1181-----
1182
1183- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1184 how long the test file should take to play. Now accepts taking 2.93 secs
1185 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1186
Georg Brandl4793aa32006-07-28 18:31:39 +00001187- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1188 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1189 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001191Build
1192-----
1193
1194- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1195
Ronald Oussoren26cad082006-08-01 21:00:57 +00001196Mac
1197---
1198
1199- PythonLauncher now works correctly when the path to the script contains
1200 characters that are treated specially by the shell (such as quotes).
1201
1202- Bug #1527397: PythonLauncher now launches scripts with the working directory
1203 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001204 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001205 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001212
1213Core and builtins
1214-----------------
1215
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001216- Bug #1441486: The literal representation of -(sys.maxint - 1)
1217 again evaluates to a int object, not a long.
1218
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001219- Bug #1501934: The scope of global variables that are locally assigned
1220 using augmented assignment is now correctly determined.
1221
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001222- Bug #927248: Recursive method-wrapper objects can now safely
1223 be released.
1224
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001225- Bug #1417699: Reject locale-specific decimal point in float()
1226 and atof().
1227
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001228- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1229 omit a default "error" argument for NULL pointer. This allows
1230 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001231
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001232- Bug #1519018: 'as' is now validated properly in import statements.
1233
Neal Norwitz28746ab2006-07-09 22:14:42 +00001234- On 64 bit systems, int literals that use less than 64 bits are
1235 now ints rather than longs.
1236
Neal Norwitzed657552006-07-10 00:04:44 +00001237- Bug #1512814, Fix incorrect lineno's when code at module scope
1238 started after line 256.
1239
Tim Peters32a83612006-07-10 21:08:24 +00001240- New function ``sys._current_frames()`` returns a dict mapping thread
1241 id to topmost thread stack frame. This is for expert use, and is
1242 especially useful for debugging application deadlocks. The functionality
1243 was previously available in Fazal Majid's ``threadframe`` extension
1244 module, but it wasn't possible to do this in a wholly threadsafe way from
1245 an extension.
1246

Martin v. Löwis77621582006-07-30 13:27:31 +00001250- Bug #1257728: Mention Cygwin in distutils error message about a missing
1251 VS 2003.
1252
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001253- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1254
Tim Peters32a83612006-07-10 21:08:24 +00001255- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001256 environment variable to be set in order to the SDK environment
1257 for finding the compiler, include files, etc.
1258
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001259- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1260
Nick Coghlan2d792252006-07-06 13:47:18 +00001261- warnings.py now ignores ImportWarning by default
1262
Thomas Woutersadd19112006-07-05 11:03:49 +00001263- string.Template() now correctly handles tuple-values. Previously,
1264 multi-value tuples would raise an exception and single-value tuples would
1265 be treated as the value they contain, instead.
1266
Martin v. Löwisede77f52006-07-03 13:01:35 +00001267- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1268 even if some data are received.
1269
Martin v. Löwis45482392006-07-03 12:28:58 +00001270- Bug #1267547: Put proper recursive setup.py call into the
1271 spec file generated by bdist_rpm.
1272
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001273- Bug #1514693: Update turtle's heading when switching between
1274 degrees and radians.
1275
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001276- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001277 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001278
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001279- Bug #1514703: Only setup canvas window in turtle when the canvas
1280 is created.
1281
Martin v. Löwis7596e832006-07-01 15:33:37 +00001282- Bug #1513223: .close() of a _socketobj now releases the underlying
1283 socket again, which then gets closed as it becomes unreferenced.

1286 attribute values.
1287
1288- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1289 sgmllib ('[' and ']' were not accepted).
1290
Georg Brandl1be63af2006-06-28 20:23:25 +00001291- Fix a bug in the turtle module's end_fill function.
1292
Brett Cannon53ab5b72006-06-22 16:49:14 +00001293- Bug #1510580: The 'warnings' module improperly required that a Warning
1294 category be either a types.ClassType and a subclass of Warning. The proper
1295 check is just that it is a subclass with Warning as the documentation states.
1296
Georg Brandlad29e632006-06-21 17:45:17 +00001297- The compiler module now correctly compiles the new try-except-finally
1298 statement (bug #1509132).
1299
Neal Norwitz60373cd2006-06-22 06:30:50 +00001300- The wsgiref package is now installed properly on Unix.
1301
Vinay Sajip28e57612006-07-01 10:45:20 +00001302- A bug was fixed in logging.config.fileConfig() which caused a crash on
1303 shutdown when fileConfig() was called multiple times.
1304
Gerhard Häring762fbd32006-07-02 17:48:30 +00001305- The sqlite3 module did cut off data from the SQLite database at the first
1306 null character before sending it to a custom converter. This has been fixed
1307 now.
1308
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001309Extension Modules
1310-----------------
1311
Tim Peters112aad32006-07-19 00:03:19 +00001312- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1313 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1314 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001315
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001316- Assigning None to pointer type fields in ctypes structures possible
1317 overwrote the wrong fields, this is fixed now.
1318
1319- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1320 on non-Windows platforms.
1321
1322- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1323 integer or long, without range checking.
1324
1325- Patch #1517790: It is now possible to use custom objects in the ctypes
1326 foreign function argtypes sequence as long as they provide a from_param
1327 method, no longer is it required that the object is a ctypes type.
1328
1329- The '_ctypes' extension module now works when Python is configured
1330 with the --without-threads option.
1331
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001332- Bug #1513646: os.access on Windows now correctly determines write
1333 access, again.
1334
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001335- Bug #1512695: cPickle.loads could crash if it was interrupted with
1336 a KeyboardInterrupt.
1337
Neal Norwitza12aa882006-07-06 06:45:08 +00001338- Bug #1296433: parsing XML with a non-default encoding and
1339 a CharacterDataHandler could crash the interpreter in pyexpat.
1340
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001341- Patch #1516912: improve Modules support for OpenVMS.
1342
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001343Build
1344-----
1345
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001346- Automate Windows build process for the Win64 SSL module.
1347
Tim Peters32a83612006-07-10 21:08:24 +00001348- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001349 Previously, the slight difference could cause compilation errors of the
1350 'zlib' module on systems with more than one version of zlib.
1351
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001352- The MSI compileall step was fixed to also support a TARGETDIR
1353 with spaces in it.
1354
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001355- Bug #1517388: sqlite3.dll is now installed on Windows independent
1356 of Tcl/Tk.
1357
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001358- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001359 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001361Tests
1362-----
1363
1364- Call os.waitpid() at the end of tests that spawn child processes in order
1365 to minimize resources (zombies).
1366
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001367Documentation
1368-------------
1369
Nick Coghlan2d792252006-07-06 13:47:18 +00001370- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1371 documentation for the warnings module.
1372
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001373- Patch #1509163: MS Toolkit Compiler no longer available.
1374

Nick Coghlanc649ec52006-05-29 12:43:05 +00001378What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001379================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001380
Anthony Baxterd1136802006-06-19 12:04:15 +00001381*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001382
1383Core and builtins
1384-----------------
1385
Georg Brandla56b9152006-06-19 06:35:54 +00001386- Patch #1507676: Error messages returned by invalid abstract object operations
1387 (such as iterating over an integer) have been improved and now include the
1388 type of the offending object to help with debugging.
1389
Brett Cannonea3912b2006-06-13 21:46:41 +00001390- Bug #992017: A classic class that defined a __coerce__() method that returned
1391 its arguments swapped would infinitely recurse and segfault the interpreter.
1392
Neal Norwitz909eb122006-06-12 02:13:21 +00001393- Fix the socket tests so they can be run concurrently.
1394
Neal Norwitzb9845e72006-06-12 02:11:18 +00001395- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001396 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001397
Brett Cannon22565aa2006-06-09 22:31:23 +00001398- Bug #532646: object.__call__() will continue looking for the __call__
1399 attribute on objects until one without one is found. This leads to recursion
1400 when you take a class and set its __call__ attribute to an instance of the
1401 class. Originally fixed for classic classes, but this fix is for new-style.
1402 Removes the infinite_rec_3 crasher.
1403
Georg Brandl24250812006-06-09 18:45:48 +00001404- The string and unicode methods startswith() and endswith() now accept
1405 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1406
Brett Cannonde3b0522006-06-08 17:00:45 +00001407- Buffer objects, at the C level, never used the char buffer
1408 implementation even when the char buffer for the wrapped object was
1409 explicitly requested (originally returned the read or write buffer).
1410 Now a TypeError is raised if the char buffer is not present but is
1411 requested.
1412
Georg Brandlddbaa662006-06-04 21:56:52 +00001413- Patch #1346214: Statements like "if 0: suite" are now again optimized
1414 away like they were in Python 2.4.
1415
Georg Brandlb7c8f542006-05-27 12:30:25 +00001416- Builtin exceptions are now full-blown new-style classes instead of
1417 instances pretending to be classes, which speeds up exception handling
1418 by about 80% in comparison to 2.5a2.
1419
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001420- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1421 Unicode 4.1.
1422
Georg Brandlf4ef1162006-05-26 18:03:31 +00001423- Patch #921466: sys.path_importer_cache is now used to cache valid and
1424 invalid file paths for the built-in import machinery which leads to
1425 fewer open calls on startup.
1426
Tim Peters696cf432006-05-24 21:10:40 +00001427- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1428 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1429 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1430 the number of input digits (it was and remains linear-time for bases
1431 2, 4, 8, 16 and 32).
1432
Tim Petersb713ec22006-05-23 18:45:30 +00001433- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1434 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1435 an integer close to ``sys.maxint``. This was repaired by patch
1436 #1335972, which also gives a nice speedup.
1437
Richard Jonescebbefc2006-05-23 18:28:17 +00001438- Patch #1337051: reduced size of frame objects.
1439
1440- PyErr_NewException now accepts a tuple of base classes as its
1441 "base" parameter.
1442
Richard Jones7c88dcc2006-05-23 10:37:38 +00001443- Patch #876206: function call speedup by retaining allocated frame
1444 objects.
1445
Georg Brandl7b90e162006-05-18 07:01:27 +00001446- Bug #1462152: file() now checks more thoroughly for invalid mode
1447 strings and removes a possible "U" before passing the mode to the
1448 C library function.
1449
Neal Norwitz1004a532006-05-15 07:17:23 +00001450- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1451
Neal Norwitz373f0a72006-05-15 07:04:36 +00001452- Bug #1487966: Fix SystemError with conditional expression in assignment
1453
Martin v. Löwis879768d2006-05-11 13:28:43 +00001454- WindowsError now has two error code attributes: errno, which carries
1455 the error values from errno.h, and winerror, which carries the error
1456 values from winerror.h. Previous versions put the winerror.h values
1457 (from GetLastError()) into the errno attribute.
1458
Martin v. Löwis77736712006-05-04 05:51:03 +00001459- Patch #1475845: Raise IndentationError for unexpected indent.
1460
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001461- Patch #1479181: split open() and file() from being aliases for each other.
1462
Tim Peters44bd9862006-06-01 13:49:23 +00001463- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1464 methods were always silently ignored by dictionaries when comparing keys.
1465 They are now passed through (except when using the C API function
1466 ``PyDict_GetItem()``, whose semantics did not change).
1467
1468- Bug #1456209: In some obscure cases it was possible for a class with a
1469 custom ``__eq__()`` method to confuse dict internals when class instances
1470 were used as a dict's keys and the ``__eq__()`` method mutated the dict.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001473Extension Modules
1474-----------------
1475
Trent Mick960a3f82006-06-28 20:30:41 +00001476- Bug #1295808: expat symbols should be namespaced in pyexpat
1477
1478- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1479
Brett Cannon6ee7d012006-06-08 16:23:04 +00001480- Change binascii.hexlify to accept a read-only buffer instead of only a char
1481 buffer and actually follow its documentation.
1482
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001483- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1484
Nick Coghlanc649ec52006-05-29 12:43:05 +00001485- Patch #1478788 (modified version): The functional extension module has
1486 been renamed to _functools and a functools Python wrapper module added.
1487 This provides a home for additional function related utilities that are
1488 not specifically about functional programming. See PEP 309.
1489
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001490- Patch #1493701: performance enhancements for struct module.
1491
Georg Brandl378d5922006-05-17 14:26:50 +00001492- Patch #1490224: time.altzone is now set correctly on Cygwin.
1493
Georg Brandl8d3342b2006-05-16 07:38:27 +00001494- Patch #1435422: zlib's compress and decompress objects now have a
1495 copy() method.
1496
Andrew MacIntyre92913322006-06-13 15:04:24 +00001497- Patch #1454481: thread stack size is now tunable at runtime for thread
1498 enabled builds on Windows and systems with Posix threads support.
1499
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001500- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1501 (up to the system limit of 32K characters).
1502
1503- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1504 As a result, these functions now raise WindowsError instead of OSError.
1505
Tim Peters7a822da2006-05-25 21:50:17 +00001506- ``time.clock()`` on Win64 should use the high-performance Windows
1507 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1508 Windows platforms).
1509
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001510- Calling Tk_Init twice is refused if the first call failed as that
1511 may deadlock.
1512
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001513- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1514 accept it without potentially using an uninitialized pointer.
1515
1516- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1517 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1518 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001519
Gregory P. Smith372b5832006-06-05 18:48:21 +00001520- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001521 [pybsddb project SF patch number 1466734]
1522
Gregory P. Smith372b5832006-06-05 18:48:21 +00001523- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1524 parameter is supplied. [SF pybsddb bug #1477863]
1525
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001526- bsddb: the __len__ method of a DB object has been fixed to return correct
1527 results. It could previously incorrectly return 0 in some cases.
1528 Fixes SF bug 1493322 (pybsddb bug 1184012).
1529
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001530- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1531 aborts the db transaction safely when a modifier callback fails.
1532 Fixes SF python patch/bug #1408584.
1533
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001534- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001535 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001536 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1537 database calls that would previously deadlock. [SF python bug #775414]
1538
Vinay Sajip28e57612006-07-01 10:45:20 +00001539- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001540
Walter Dörwald4994d952006-06-19 08:07:50 +00001541- Patch #1506645: add Python wrappers for the curses functions
1542 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001543

1545-------
1546
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001547- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1548 functions.
1549
Martin v. Löwis3798da02006-06-17 18:44:27 +00001550- Patch #812986: Update turtle output even if not tracing.
1551
Vinay Sajip28e57612006-07-01 10:45:20 +00001552- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001553 Tkinter.BaseWidget.
1554
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001555- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1556
Martin v. Löwis337487e2006-06-17 09:15:14 +00001557- Patch #763580: Add name and value arguments to Tkinter variable
1558 classes.
1559
Georg Brandl83cc0d02006-06-14 08:50:03 +00001560- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1561 mime.types file for determining MIME types.
1562
Georg Brandl2605ca82006-06-14 06:08:31 +00001563- Bug #1339007: Shelf objects now don't raise an exception in their
1564 __del__ method when initialization failed.
1565
Martin v. Löwisd8251432006-06-14 05:21:04 +00001566- Patch #1455898: The MBCS codec now supports the incremental mode for
1567 double-byte encodings.
1568
Tim Peters43898b42006-06-14 04:09:25 +00001569- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1570 guarantee that adjacent triples in the return list always describe
1571 non-adjacent blocks. Previously, a pair of matching blocks could end
1572 up being described by multiple adjacent triples that formed a partition
1573 of the matching pair.
1574
Greg Ward0e0c9f42006-06-11 16:24:11 +00001575- Bug #1498146: fix optparse to handle Unicode strings in option help,
1576 description, and epilog.
1577
Greg Wardd1c797e2006-06-11 14:42:41 +00001578- Bug #1366250: minor optparse documentation error.
1579
Greg Ward7f547402006-06-11 00:40:49 +00001580- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1581 clarify docs.
1582
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001583- The wsgiref package has been added to the standard library.
1584
Nick Coghlan676725d2006-06-08 13:54:49 +00001585- The functions update_wrapper() and wraps() have been added to the functools
1586 module. These make it easier to copy relevant metadata from the original
1587 function when writing wrapper functions.
1588
Tim Petersd6a9eef2006-06-05 01:48:21 +00001589- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1590 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001591
Martin v. Löwis3f767792006-06-04 19:36:28 +00001592- Patch #1359618: Speed up charmap encoder by using a trie structure
1593 for lookup.
1594
Tim Petersd609b1a2006-06-02 23:22:51 +00001595- The functions in the ``pprint`` module now sort dictionaries by key
1596 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1597 if and only if its display required more than one line, although that
1598 wasn't documented. The new behavior increases predictability; e.g.,
1599 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1600
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001601- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1602 (thanks for J. J. Lee).
1603
Georg Brandl2b330372006-05-28 20:23:12 +00001604- Patch #1496206: improve urllib2 handling of passwords with respect to
1605 default HTTP and HTTPS ports.
1606
George Yoshidaf3c65de2006-05-28 16:39:09 +00001607- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1608
Bob Ippolito7298f272006-05-23 18:43:47 +00001609- Patch #1281707: speed up gzip.readline.
1610
Georg Brandlb89316f2006-05-17 15:51:16 +00001611- Patch #1180296: Two new functions were added to the locale module:
1612 format_string() to get the effect of "format % items" but locale-aware,
1613 and currency() to format a monetary number with currency sign.
1614
Georg Brandle3a25832006-05-17 14:56:04 +00001615- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1616 and several features added, such as speed and geometry control.
1617
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001618- Patch #1488881: add support for external file objects in bz2 compressed
1619 tarfiles.
1620
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001621- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1622 stdout arguments, making it possible to redirect input and output
1623 for remote debugging.
1624
1625- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1626 a couple of issues, notably handling of long file names using the
1627 GNU LONGNAME extension.
1628
1629- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1630 new flag when ``name`` is already the name of an option flag.
1631
1632- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1633 package.
1634
1635- Patch #1472854: make the rlcompleter.Completer class usable on non-
1636 UNIX platforms.
1637
1638- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1639
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001640- Bug #1472827: correctly escape newlines and tabs in attribute values in
1641 the saxutils.XMLGenerator class.

1673
1674*Release date: 27-APR-2006*

1676Core and builtins
1677-----------------
1678
Thomas Heller1b046642006-04-18 18:51:06 +00001679- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1680 by converting these apis from macros into exported functions again:
1681
1682 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1683 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1684 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1685 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1686 PyRun_String Py_CompileString
1687
Martin v. Löwis45294a92006-04-18 06:24:08 +00001688- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1689
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001690- All uses of PyStructSequence_InitType have been changed to initialize
1691 the type objects only once, even if the interpreter is initialized
1692 multiple times.
1693
Neal Norwitz61546162006-04-14 05:20:28 +00001694- Bug #1454485, array.array('u') could crash the interpreter. This was
1695 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1696 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1697
1698- Py_UNICODE is unsigned. It was always documented as unsigned, but
1699 due to a bug had a signed value in previous versions.
1700
Tim Peters3a5e8b12006-04-11 01:44:07 +00001701- Patch #837242: ``id()`` of any Python object always gives a positive
1702 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1703 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001704 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001705 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001706
Tim Peters3a5e8b12006-04-11 01:44:07 +00001707 def __hash__(self):
1708 return id(self) # WRONG
1709
1710 because a hash result must be a (short) Python int but it was always
1711 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001712 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001713 was always usable as a hash value before this patch. That's no longer
1714 necessarily so.
1715
1716- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001717 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001718 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001719 #1454844)
1720
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001721- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1722 involving generators that have paused outside of any ``try`` or ``with``
1723 blocks. (In 2.5a1, a paused generator that was part of a reference
1724 cycle could not be garbage collected, regardless of whether it was
1725 paused in a ``try`` or ``with`` block.)

1732
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001733- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1734 fails with an error condition.
1735
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001736- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1737
1738- Bug #1117761: bsddb.*open() no longer raises an exception when using
1739 the cachesize parameter.
1740
1741- Bug #1149413: bsddb.*open() no longer raises an exception when using
1742 a temporary db (file=None) with the 'n' flag to truncate on open.
1743
1744- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1745 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001746
Armin Rigoa9017c32006-04-19 11:50:27 +00001747- Patch #1062014: AF_UNIX sockets under Linux have a special
1748 abstract namespace that is now fully supported.

1751-------
1752
Peter Astrand7d1d4362006-07-14 14:04:45 +00001753- Bug #1223937: subprocess.CalledProcessError reports the exit status
1754 of the process using the returncode attribute, instead of
1755 abusing errno.
1756
Tim Peters711bf302006-04-25 03:31:36 +00001757- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1758 a doctest to be skipped (the code is not run, and the expected output
1759 or exception is ignored).
1760
Nick Coghlanda2268f2006-04-24 04:37:15 +00001761- Fixed contextlib.nested to cope with exceptions being raised and
1762 caught inside exit handlers.
1763
Greg Wardab05edc2006-04-23 03:47:58 +00001764- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1765 hex, octal, or binary; add ``append_const`` action; keep going if
1766 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1767 added ``epilog`` for better help generation).
1768
Tim Peters21fbd572006-04-21 21:18:10 +00001769- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1770 called from a thread spawned as a side effect of importing a module.
1771
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001772- The pydoc module now supports documenting packages contained in
1773 .zip or .egg files.
1774
1775- The pkgutil module now has several new utility functions, such
1776 as ``walk_packages()`` to support working with packages that are either
1777 in the filesystem or zip files.

Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001779- The mailbox module can now modify and delete messages from
1780 mailboxes, in addition to simply reading them. Thanks to Gregory
1781 K. Johnson for writing the code, and to the 2005 Google Summer of
1782 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001783

Anthony Baxtere29002c2006-04-12 12:07:31 +00001793- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1794 Windows. Bug #1469163.
1795
Phillip J. Eby47032112006-04-11 01:07:43 +00001796- The warnings, linecache, inspect, traceback, site, and doctest modules
1797 were updated to work correctly with modules imported from zipfiles or
1798 via other PEP 302 __loader__ objects.
1799

1806
Skip Montanaro262fb922006-04-21 02:31:07 +00001807- The pstats.Stats class accepts an optional stream keyword argument to
1808 direct output to an alternate file-like object.
1809
Anthony Baxter51bcb682006-04-05 14:51:42 +00001810Build
1811-----
1812
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001813- The Makefile now has a reindent target, which runs reindent.py on
1814 the library.
1815
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001816- Patch #1470875: Building Python with MS Free Compiler
1817
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001818- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001819
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001820- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1821 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001822 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001823 CXX from --with-cxx-main, see description in README.
1824
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001825- Patch #1429775: Link extension modules with the shared libpython.
1826
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001827- Fixed a libffi build problem on MIPS systems.
1828
Tim Peters8931ff12006-05-13 23:28:20 +00001829- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1830 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1831 and "%zu" for unsigned integers of type ``size_t``.
1832
Anthony Baxter51bcb682006-04-05 14:51:42 +00001833Tests
1834-----
1835
Nick Coghlanda2268f2006-04-24 04:37:15 +00001836- test_contextlib now checks contextlib.nested can cope with exceptions
1837 being raised and caught inside exit handlers.
1838
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001839- test_cmd_line now checks operation of the -m and -c command switches
1840
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001841- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1842 it separately and by hand. It also wasn't cleaning up its changes to
1843 the current Decimal context.
1844
Thomas Woutersabd08882006-04-26 15:53:30 +00001845- regrtest.py now has a -M option to run tests that test the new limits of
1846 containers, on 64-bit architectures. Running these tests is only sensible
1847 on 64-bit machines with more than two gigabytes of memory. The argument
1848 passed is the maximum amount of memory for the tests to use.
1849
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001850Tools

1857-------------
1858
Tim Petersb06d28c2006-05-12 01:57:59 +00001859- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1860
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001861- PEP 343: Added Context Types section to the library reference
1862 and attempted to bring other PEP 343 related documentation into
1863 line with the implementation and/or python-dev discussions.
1864
Tim Peters8dc73d22006-04-24 02:03:16 +00001865- Bug #1337990: clarified that ``doctest`` does not support examples
1866 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001869What's New in Python 2.5 alpha 1?
1870=================================
1871
Anthony Baxterebed3f62006-04-03 15:03:44 +00001872*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001873
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001874Core and builtins
1875-----------------
1876
Nick Coghlan43832302006-04-23 17:04:07 +00001877- PEP 338: -m command line switch now delegates to runpy.run_module
1878 allowing it to support modules in packages and zipfiles
1879
Martin v. Löwisc661b882006-04-20 04:54:23 +00001880- On Windows, .DLL is not an accepted file name extension for
1881 extension modules anymore; extensions are only found if they
1882 end in .PYD.
1883
Martin v. Löwisea62d252006-04-03 10:56:49 +00001884- Bug #1421664: sys.stderr.encoding is now set to the same value as
1885 sys.stdout.encoding.
1886
Neal Norwitz92e212f2006-04-03 04:48:37 +00001887- __import__ accepts keyword arguments.
1888
Georg Brandlccadf842006-03-31 18:54:53 +00001889- Patch #1460496: round() now accepts keyword arguments.
1890
Anthony Baxter262c00a2006-03-30 10:53:17 +00001891- Fixed bug #1459029 - unicode reprs were double-escaped.
1892
Hye-Shik Changd478f342006-03-23 12:32:36 +00001893- Patch #1396919: The system scope threads are reenabled on FreeBSD
1894 5.4 and later versions.
1895
Neal Norwitze98ccf62006-03-23 05:39:47 +00001896- Bug #1115379: Compiling a Unicode string with an encoding declaration
1897 now gives a SyntaxError.
1898
Georg Brandlabd1ff82006-03-18 07:59:59 +00001899- Previously, Python code had no easy way to access the contents of a
1900 cell object. Now, a ``cell_contents`` attribute has been added
1901 (closes patch #1170323).
1902
Tim Peterscf79aac2006-03-16 01:14:46 +00001903- Patch #1123430: Python's small-object allocator now returns an arena to
1904 the system ``free()`` when all memory within an arena becomes unused
1905 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1906 freed. Some applications will see a drop in virtual memory size now,
1907 especially long-running applications that, from time to time, temporarily
1908 use a large number of small objects. Note that when Python returns an
1909 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001910 platform C library will in turn return that memory to the operating system.
1911 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001912 appears to be effective at least on Microsoft C and gcc-based systems.
1913 Thanks to Evan Jones for hard work and patience.
1914
Georg Brandl533ff6f2006-03-08 18:09:27 +00001915- Patch #1434038: property() now uses the getter's docstring if there is
1916 no "doc" argument given. This makes it possible to legitimately use
1917 property() as a decorator to produce a read-only property.
1918
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001919- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1920 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1921 of requiring an int or long in slicing and a few other contexts, enabling
1922 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1923
Neal Norwitz995acdf2006-03-07 05:01:00 +00001924- Fixed various bugs reported by Coverity's Prevent tool.
1925
Brett Cannonbf364092006-03-01 04:25:17 +00001926- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1927 new exception base class, BaseException, which has a new message attribute.
1928 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1929 Raising a string exception now raises a DeprecationWarning.
1930
Thomas Woutersfb609f42006-02-28 16:37:25 +00001931- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1932 explicitly relative, using 'from .module import name' to mean 'from the same
1933 package as this module is in. Imports without dots still default to the
1934 old relative-then-absolute, unless 'from __future__ import
1935 absolute_import' is used.
1936
Brett Cannona7446e32006-02-27 23:39:10 +00001937- Properly check if 'warnings' raises an exception (usually when a filter set
1938 to "error" is triggered) when raising a warning for raising string
1939 exceptions.
1940
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001941- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001942 The name was removed from Include/code.h.
1943
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001944- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001945
Guido van Rossum1968ad32006-02-25 22:38:04 +00001946- Patch 1433928:
1947 - The copy module now "copies" function objects (as atomic objects).
1948 - dict.__getitem__ now looks for a __missing__ hook before raising
1949 KeyError.
1950
Tim Peters84ef21c2006-02-28 20:39:06 +00001951- PEP 343: with statement implemented. Needs ``from __future__ import
1952 with_statement``. Use of 'with' as a variable will generate a warning.
1953 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001954 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001955 The following objects have __context__ methods:
1956 - The built-in file type.
1957 - The thread.LockType type.
1958 - The following types defined by the threading module:
1959 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1960 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001961
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001962- Fix the encodings package codec search function to only search
1963 inside its own package. Fixes problem reported in patch #1433198.
1964
1965 Note: Codec packages should implement and register their own
1966 codec search function. PEP 100 has the details.
1967
Tim Peters9ea89d22006-06-04 03:26:02 +00001968- PEP 353: Using ``Py_ssize_t`` as the index type.
1969
1970- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1971 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1972 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1973 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1974 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001975
Neal Norwitzfc76d632006-01-10 06:03:13 +00001976- Patch #1400181, fix unicode string formatting to not use the locale.
1977 This is how string objects work. u'%f' could use , instead of .
1978 for the decimal point. Now both strings and unicode always use periods.
1979
Neal Norwitz671b9e32006-01-09 07:07:12 +00001980- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1981 configure would break checking curses.h.
1982
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001983- Bug #959576: The pwd module is now builtin. This allows Python to be
1984 built on UNIX platforms without $HOME set.
1985
Neal Norwitzc10978f2005-12-19 06:07:16 +00001986- Bug #1072182, fix some potential problems if characters are signed.
1987
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001988- Bug #889500, fix line number on SyntaxWarning for global declarations.
1989
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001990- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1991
Neal Norwitze7214a12005-12-18 05:03:17 +00001992- Support for converting hex strings to floats no longer works.
1993 This was not portable. float('0x3') now raises a ValueError.
1994
Barry Warsaw2a38a862005-12-18 01:27:35 +00001995- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001996 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001997 is now displayed in interactive prompt banner.
1998
Georg Brandlfa166682005-12-17 21:45:17 +00001999- Implementation of PEP 341 - Unification of try/except and try/finally.
2000 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002001 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002002
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002003- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2004 now encodes backslash correctly.
2005
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002006- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2007
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002008- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002009 and long longs.
2010
Neal Norwitz67715f02005-11-09 06:59:35 +00002011- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002012 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002013 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002014
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002015- Replaced most Unicode charmap codecs with new ones using the
2016 new Unicode translate string feature in the builtin charmap
2017 codec; the codecs were created from the mapping tables available
2018 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2019 encodings now include a mapping for the Apple logo)
2020
Tim Peterse3547fd2005-12-16 23:13:57 +00002021- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002022
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002023- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002024
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002025- A new AST parser implementation was completed. The abstract
2026 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002027 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002028
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002029- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002030 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2031
Neal Norwitz708e51a2005-10-03 04:48:15 +00002032- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2033
Neal Norwitz11bd1192005-10-03 00:54:56 +00002034- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2035 Provide a warning when a directory is passed on the command line.
2036
Neal Norwitz40d37812005-10-02 01:48:49 +00002037- Fix segfault with invalid coding.
2038
2039- SF bug #772896: unknown encoding results in MemoryError.
2040
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002041- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002042 supported a __len__() method which evaluated to False when the iterator
2043 was empty.
2044
Guido van Rossum630db602005-09-20 18:49:54 +00002045- On 64-bit platforms, when __len__() returns a value that cannot be
2046 represented as a C int, raise OverflowError.
2047
Skip Montanarof8948ca2005-09-19 03:54:46 +00002048- test__locale is skipped on OS X < 10.4 (only partial locale support is

Georg Brandl80bbf3f2005-09-14 19:38:29 +00002051- SF bug #893549: parsing keyword arguments was broken with a few format
2052 codes.
2053
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002054- Changes donated by Elemental Security to make it work on AIX 5.3
2055 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2056 bug #105470: test_pwd fails on 64bit system (Opteron).
2057
Guido van Rossum539c6622005-09-14 17:49:54 +00002058- Changes donated by Elemental Security to make it work on HP-UX 11 on
2059 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2060
Georg Brandl4550b8d2005-08-26 06:43:52 +00002061- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002062 (fixes bug #1119418).
2063
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002064- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2065
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002066- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2067 exceptions that cause a function to exit.
2068
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002069- The implementation of set() and frozenset() was revised to use its
2070 own internal data structure. Memory consumption is reduced by 1/3
2071 and there are modest speed-ups as well. The API is unchanged.
2072
Tim Petersde7990b2005-07-17 23:45:23 +00002073- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2074
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002075- SF bug #1229429: PyObject_CallMethod failed to decrement some
2076 reference counts in some error exit cases.
2077
Tim Petersecc6e6a2005-07-10 22:30:55 +00002078- SF bug #1185883: Python's small-object memory allocator took over
2079 a block managed by the platform C library whenever a realloc specified
2080 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002081 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002082 portable way to copy data from the C-managed block into Python's
2083 small-object space without risking a memory fault. Python's small-object
2084 realloc now leaves such blocks under the control of the platform C
2085 realloc.
2086
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002087- SF bug #1232517: An overflow error was not detected properly when
2088 attempting to convert a large float to an int in os.utime().
2089
Raymond Hettinger3296e692005-06-29 23:29:56 +00002090- SF bug #1224347: hex longs now print with lowercase letters just
2091 like their int counterparts.
2092
Michael W. Hudson188d4362005-06-20 16:52:57 +00002093- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2094 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2095 interpreter states; back out that fix and do a better job (see
2096 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2097 for a longer write-up of the problem).
2098
Michael W. Hudsondf888462005-06-03 14:41:55 +00002099- SF patch #1180995: marshal now uses a binary format by default when
2100 serializing floats.
2101
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002102- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2103 the routines that promise to produce IEEE 754 binary representations
2104 of floats now simply copy bytes around.
2105
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002106- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2107 278.
2108
Brett Cannonc3647ac2005-04-26 03:45:26 +00002109- patch #1109424: int, long, float, complex, and unicode now check for the
2110 proper magic slot for type conversions when subclassed. Previously the
2111 magic slot was ignored during conversion. Semantics now match the way
2112 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002113 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002114 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002115 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002116
Barry Warsawc8d907c2005-04-19 23:43:40 +00002117- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2118 NULL, now raise an AttributeError when attempting to set or delete the
2119 attribute. Previously a TypeError was raised, but this was inconsistent
2120 with the equivalent pure-Python implementation.
2121
Michael W. Hudson774479c2005-04-18 08:46:17 +00002122- It is now safe to call PyGILState_Release() before
2123 PyEval_InitThreads() (note that if there is reason to believe there
2124 are multiple threads around you still must call PyEval_InitThreads()
2125 before using the Python API; this fix is for extension modules that
2126 have no way of knowing if Python is multi-threaded yet).
2127
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002128- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2129 disabled caused a crash.
2130
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002131- Bug #1165306: instancemethod_new allowed the creation of a method
2132 with im_class == im_self == NULL, which caused a crash when called.
2133
Tim Petersecc6e6a2005-07-10 22:30:55 +00002134- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002135 fixes the crash seen in bug #1165761
2136
Raymond Hettinger96229b12005-03-11 06:49:40 +00002137- Added two new builtins, any() and all().
2138
Brett Cannon409d8f22005-03-05 06:47:57 +00002139- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002140 (e.g., ``class C(): pass`` is no longer a syntax error).
2141 Patch #1176012 added support to the 'parser' module and 'compiler' package
2142 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002143
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002144- Patch #1115086: Support PY_LONGLONG in structmember.
2145
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002146- Bug #1155938: new style classes did not check that __init__() was
2147 returning None.
2148
Tim Petersecc6e6a2005-07-10 22:30:55 +00002149- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002150 ('\') with a specific error message.
2151
Martin v. Löwisff232d72005-03-03 09:24:38 +00002152- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2153
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002154- Bug #1124295: the __name__ attribute of file objects was
2155 inadvertently made inaccessible in restricted mode.
2156
Tim Petersecc6e6a2005-07-10 22:30:55 +00002157- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002158 an ferror() call.
2159
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002160- min() and max() now support key= arguments with the same meaning as in
2161 list.sort().
2162
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002163- The peephole optimizer now performs simple constant folding in expressions:
2164 (2+3) --> (5).
2165
Raymond Hettingera422c342005-01-11 03:03:27 +00002166- set and frozenset objects can now be marshalled. SF #1098985.
2167
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002168- Bug #1077106: Poor argument checking could cause memory corruption
2169 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002170
Jeremy Hyltonab630502005-02-04 18:44:06 +00002171- The parser did not complain about future statements in illegal
2172 positions. It once again reports a syntax error if a future
2173 statement occurs after anything other than a doc string.
2174
Neil Schemenauercf52c072005-08-12 17:34:58 +00002175- Change the %s format specifier for str objects so that it returns a
2176 unicode instance if the argument is not an instance of basestring and
2177 calling __str__ on the argument returns a unicode instance.
2178
Tim Petersf4e69282006-02-27 17:15:31 +00002179- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2180 current thread state when the auto-GIL-state machinery knows about
2181 it (since the thread state is being deleted, continuing to remember it
2182 can't help, but can hurt if another thread happens to get created with
2183 the same thread id).
2184

Neal Norwitz10be10c2006-03-16 06:50:13 +00002201 util, whatsound, whrandom, zmod
2202
2203- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2204
2205- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002206 is deprecated. The undocumented re.engine variable no longer exists.
2207
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002208- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2209 SS2 (single-shift 2) escape sequences correctly.
2210
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002211- The unicodedata module was updated to the 4.1 version of the Unicode
2212 database. The 3.2 version is still available as unicodedata.db_3_2_0
2213 for applications that require this specific version (such as IDNA).
2214
Neal Norwitzb62c4332006-03-04 18:35:47 +00002215- The timing module is no longer built by default. It was deprecated
2216 in PEP 4 in Python 2.0 or earlier.
2217
Guido van Rossum1968ad32006-02-25 22:38:04 +00002218- Patch 1433928: Added a new type, defaultdict, to the collections module.
2219 This uses the new __missing__ hook behavior added to dict (see above).
2220
Georg Brandldbd83392006-02-20 09:42:33 +00002221- Bug #854823: socketmodule now builds on Sun platforms even when
2222 INET_ADDRSTRLEN is not defined.
2223
Georg Brandlf4f44152006-02-18 22:29:33 +00002224- Patch #1393157: os.startfile() now has an optional argument to specify
2225 a "command verb" to invoke on the file.
2226
Neal Norwitz082b2df2006-02-07 07:04:46 +00002227- Bug #876637, prevent stack corruption when socket descriptor

2229
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002230- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2231 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2232 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2235 than the system default domain.
2236
Martin v. Löwis14694662006-02-03 12:54:16 +00002237- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2238 are reported, the limit on path name lengths is removed, and stat reports
2239 WindowsError now (instead of OSError).
2240
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002241- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2331 were set in a different thread than that which called readline.
2332

2334
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002335- operator.itemgetter() and operator.attrgetter() now support retrieving

2361
Raymond Hettingerb2594052004-12-05 09:25:51 +00002362- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002375- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2376 been renamed to have only a single underscore prefix. This was done to
2377 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002378
Nick Coghlan43832302006-04-23 17:04:07 +00002379- PEP 338: new module runpy defines a run_module function to support
2380 executing modules which provide access to source code or a code object
2381 via the PEP 302 import mechanisms.
2382
Anthony Baxter93f5b932006-04-03 08:05:07 +00002383- The email module's parsedate_tz function now sets the daylight savings
2384 flag to -1 (unknown) since it can't tell from the date whether it should

2391 in attribute values.
2392
Anthony Baxterc51ee692006-04-01 00:57:31 +00002393- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002394 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002395 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002396 module will not be built.
2397
Tim Petersc17976e2006-04-01 00:26:53 +00002398- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2399 aren't officially supported here, and trying to use them will probably
2400 raise an exception some day. But dicts have been allowed, and "mostly
2401 worked", so support for them won't go away without warning.
2402
Georg Brandl338ef7d2006-03-31 18:42:16 +00002403- Bug #1445068: getpass.getpass() can now be given an explicit stream
2404 argument to specify where to write the prompt.
2405
Georg Brandl22ec80b2006-03-31 18:25:44 +00002406- Patch #1462313, bug #1443328: the pickle modules now can handle classes

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002414- Queue.Queue objects now support .task_done() and .join() methods
2415 to make it easier to monitor when daemon threads have completed
2416 processing all enqueued tasks. Patch #1455676.
2417

2421
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002422- email 4.0 package now integrated. This is largely the same as the email 3.0
2423 package that was included in Python 2.3, except that PEP 8 module names are
2424 now used (e.g. mail.message instead of email.Message). The MIME classes
2425 have been moved to a subpackage (e.g. email.mime.text instead of
2426 email.MIMEText). The old names are still supported for now. Several
2427 deprecated Message methods have been removed and lots of bugs have been
2428 fixed. More details can be found in the email package documentation.
2429
Walter Dörwald40108c92006-03-27 08:15:44 +00002430- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2431 (a subclass of tuple) that provides incremental decoders and encoders
2432 (a way to use stateful codecs without the stream API). Python functions
2433 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2434 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2435 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002436
Walter Dörwald067db482006-03-15 22:17:27 +00002437- Patch #1359365: Calling next() on a closed StringIO.String object raises
2438 a ValueError instead of a StopIteration now (like file and cString.String do).
2439 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2440 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002441
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002442- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002490 specifications, raises IOErrors when proxies for unsupported protocols
2491 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002514 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2515 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2516 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2517 Ronald L. Rivest offered this advice for Python:
2518
2519 "The consensus of researchers in this area (at least as
2520 expressed at the NIST Hash Function Workshop 10/31/05),
2521 is that SHA-256 is a good choice for the time being, but
2522 that research should continue, and other alternatives may
2523 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002524
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002525- Added a subset of Fredrik Lundh's ElementTree package. Available

2594
Georg Brandla4a8b822005-07-15 09:13:21 +00002595- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2596 parameter, but uses the usual "kwargs=None".
2597
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002598- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002599 Patch #1209527 (Contributed by Connelly).
2600
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002601- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2602 to W3C name (404 -> 'Not Found'). RFE #1216944.
2603
Georg Brandl9e43acf2005-07-04 17:16:07 +00002604- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2605 as this can cause problems with apps closing all file descriptors.
2606
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002607- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002608 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002609

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002617- The tokenize module now detects and reports indentation errors.
2618 Bug #1224621.
2619
Raymond Hettinger68c04532005-06-10 11:05:19 +00002620- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002621 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002622 the generate_tokens() function now accepts a callable argument that
2623 terminates by raising StopIteration.
2624
Georg Brandl9166e1a2005-06-04 09:20:03 +00002625- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2628 component of the path.
2629
Skip Montanaro174dd222005-05-14 20:54:16 +00002630- Patch #1120353: The xmlrpclib module provides better, more transparent,
2631 support for datetime.{datetime,date,time} objects. With use_datetime set
2632 to True, applications shouldn't have to fiddle with the DateTime wrapper
2633 class at all.
2634
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002635- distutils.commands.upload was added to support uploading distribution

2639 them to PyPI.
2640
Raymond Hettinger267b8682005-03-27 10:47:39 +00002641- decimal operator and comparison methods now return NotImplemented
2642 instead of raising a TypeError when interacting with other types. This
2643 allows other classes to implement __radd__ style methods and have them
2644 work as expected.
2645
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002646- Bug #1163325: Decimal infinities failed to hash. Attempting to
2647 hash a NaN raised an InvalidOperation instead of a TypeError.
2648
Tim Petersecc6e6a2005-07-10 22:30:55 +00002649- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2683
Guido van Rossumd0641422005-02-03 15:01:24 +00002684- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2685 disables recursive traversal through instance attributes, which can
2686 be exploited in various ways.
2687
Tim Peterse3547fd2005-12-16 23:13:57 +00002688- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002689 flags on the HTTP listening socket.
2690
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002691- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2692 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2693
Fred Drakefbdeaad2006-07-29 16:56:15 +00002694- Patches #893642, #1039083: add allow_none, encoding arguments to
2695 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002696
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002697- Bug #1110478: Revert os.environ.update to do putenv again.
2698
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002699- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2700
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002701- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2702
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002703- Enhancements to the csv module:
2704
2705 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002706 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002707 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002708 + Dialect parameter parsing has been re-implemented to improve error
2709 reporting.
2710 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2711 dictates.
2712 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002713 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002714 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002715 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2716 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002717 + reader now allows \r characters to be quoted (previously it only allowed
2718 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002719 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002720 + Dialect classes passed to the module are no longer instantiated by
2721 the module before being parsed (the former validation scheme required
2722 this, but the mechanism was unreliable).
2723 + The dialect registry now contains instances of the internal
2724 C-coded dialect type, rather than references to python objects.
2725 + the internal c-coded dialect type is now immutable.
2726 + register_dialect now accepts the same keyword dialect specifications
2727 as the reader and writer, allowing the user to register dialects
2728 without first creating a dialect class.
2729 + a configurable limit to the size of parsed fields has been added -
2730 previously, an unmatched quote character could result in the entire
2731 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002732 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002733 the parser field size limit (returning the former limit). The initial
2734 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002735 + A line_num attribute has been added to the reader object, which tracks
2736 the number of lines read from the source iterator. This is not
2737 the same as the number of records returned, as records can span
2738 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002739 + reader and writer objects were not being registered with the cyclic-GC.
2740 This has been fixed.
2741
Brett Cannone6539c42005-01-08 02:43:53 +00002742- _DummyThread objects in the threading module now delete self.__block that is
2743 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2744 lock primitives tend to be limited in number and thus should not be wasted on
2745 a _DummyThread object. Fixes bug #1089632.
2746
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002747- The imghdr module now detects Exif files.
2748
Raymond Hettinger6065d322004-12-20 23:51:53 +00002749- StringIO.truncate() now correctly adjusts the size attribute.
2750 (Bug #951915).
2751
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002752- locale.py now uses an updated locale alias table (built using
2753 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2754 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002755 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002756
Raymond Hettinger3557f422004-12-07 12:02:02 +00002757- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2758
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002759- the pickle module no longer accepts the deprecated None option in the
2760 args tuple returned by __reduce__().
2761
Brett Cannon84667c02004-12-07 03:25:18 +00002762- optparse now optionally imports gettext. This allows its use in setup.py.
2763
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002764- the pickle module no longer uses the deprecated bin parameter.
2765
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002766- the shelve module no longer uses the deprecated binary parameter.
2767
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002768- the pstats module no longer uses the deprecated ignore() method.
2769
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002770- the filecmp module no longer uses the deprecated use_statcache argument.
2771
Raymond Hettinger664347b2004-12-04 21:21:53 +00002772- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2773 extended or overridden by subclasses. Formerly, the subclassed method would
2774 be ignored by the rest of the module. (Bug #1078905).
2775
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002776- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002777 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002778
Walter Dörwald36733692004-12-22 12:50:50 +00002779- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2780 once when a size argument is given. This prevents a buffer overflow in the
2781 tokenizer with very long source lines.
2782
Barry Warsaw538561e2006-01-01 21:48:54 +00002783- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2784 immediately after creating the object, without any intervening
2785 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002786
Skip Montanaro05885812005-01-16 20:48:27 +00002787- The reconvert.quote function can now emit triple-quoted strings. The
2788 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002789
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002790- ``UserString.MutableString`` now supports negative indices in
2791 ``__setitem__`` and ``__delitem__``
2792
Greg Ward40407942005-03-05 02:53:17 +00002793- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2794 correctly.
2795
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002796- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2797 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2798 character even if the user has passed a size parameter to get a proper
2799 line ending. Remove the special handling of a "\r\n" that has been split
2800 between two lines.
2801
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002802- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2803 about illegal code points. The codec now supports PEP 293 style error
2804 handlers.
2805
Walter Dörwald78a78b02005-09-01 12:04:29 +00002806- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002807 from the input stream, so that the output is a byte string in the correct
2808 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002809
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002810- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2811 considering it exactly like a '*'.
2812
Walter Dörwald007f8df2005-10-09 19:42:27 +00002813- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2814 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002815
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002816- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2817
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002818- Patch #1413711: Certain patterns of differences were making difflib
2819 touch the recursion limit.
2820
Walter Dörwald58917a62006-03-31 15:26:22 +00002821- Bug #947906: An object oriented interface has been added to the calendar
2822 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002823 called as a script (e.g. via ``python -mcalendar``). Localized month and
2824 weekday names can be ouput (even if an exotic encoding is used) using
2825 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002826

Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002839- Patch #881820: look for openpty and forkpty also in libbsd.
2840
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002841- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2842 The zlib module is now builtin on Windows.
2843
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002844- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2845
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002846- Bug #1189330: configure did not correctly determine the necessary
2847 value of LINKCC if python was built with GCC 4.0.
2848
Trent Mick8321b422005-07-26 02:29:21 +00002849- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2850 vulnerability in zlib 1.2.1 and 1.2.2.
2851
Brett Cannon08cd5982005-04-24 22:26:38 +00002852- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2853 flags that change binary compatibility. Changes were also made to
2854 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002855 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002856
Bob Ippolitoed233462005-03-29 13:47:59 +00002857- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2858 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2859 no longer exists). This configure patch makes things right.
2860
Martin v. Löwise2713be2005-03-08 15:03:08 +00002861- Bug #1158607: Build with --disable-unicode again.
2862
Brett Cannon46d96232005-02-16 00:07:19 +00002863- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2864 defined. Discovered as a result of not being able to build on OS X.
2865
Brett Cannon516592f2004-12-07 00:42:59 +00002866- setup.py now uses the directories specified in LDFLAGS using the -L option
2867 and in CPPFLAGS using the -I option for adding library and include
2868 directories, respectively, for compiling extension modules against. This has
2869 led to the core being compiled using the values in CPPFLAGS. It also removes
2870 the need for the special-casing of both DarwinPorts and Fink for darwin since
2871 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2872 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2873 Fink, ``-I/opt/local/include`` for DarwinPorts).
2874
Brett Cannon43802422005-02-10 20:48:03 +00002875- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2876 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2877 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2878 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002880C API
2881-----
2882
Tim Petersc9d78aa2006-03-26 23:27:58 +00002883- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2884 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2885 is obtained via the ``PyObject_`` family, it must be released via the
2886 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2887 always been officially true, but when Python's small-object allocator was
2888 introduced, an attempt was made to cater to a few extension modules
2889 discovered at the time that obtained memory via ``PyObject_New`` but
2890 released it via ``PyMem_DEL``. It's years later, and if such code still
2891 exists it will fail now (probably with segfaults, but calling wrong
2892 low-level memory management functions can yield many symptoms).
2893
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002894- Added a C API for set and frozenset objects.
2895

2897
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002898- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2899 mapping argument now. This string is used as a mapping table. Byte values
2900 greater than the length of the string and 0xFFFE are treated as undefined
2901 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002908
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002909- Patch #1276356: New resource "urlfetch" is implemented. This enables
2910 even impatient people to run tests that require remote files.
