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
Georg Brandl5cb76c12007-03-21 09:00:39 +000015- Patch #1682205: a TypeError while unpacking an iterable is no longer
16 masked by a generic one with the message "unpack non-sequence".
17
Neal Norwitzaa754b72007-03-21 06:39:48 +000018- Remove unused file Python/fmod.c.
19
Guido van Rossum143b5642007-03-23 04:58:42 +000020- Bug #1683368: The object.__init__() and object.__new__() methods are
21 now stricter in rejecting excess arguments. The only time when
22 either allows excess arguments is when it is not overridden and the
23 other one is. For backwards compatibility, when both are
24 overridden, it is a deprecation warning (for now; maybe a Py3k
25 warning later).
26
Georg Brandl2b869942007-03-17 16:08:45 +000027- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
28 to complex using its __complex__() method before falling back to the
29 __float__() method. Therefore, the functions in the cmath module now
30 can operate on objects that define a __complex__() method.
31
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000032- Patch #1623563: allow __class__ assignment for classes with __slots__.
33 The old and the new class are still required to have the same slot names.
34
Collin Winter77c67bd2007-03-16 04:11:30 +000035- Patch #1642547: Fix an error/crash when encountering syntax errors in
36 complex if statements.
37
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000038- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
39 is called with an object that is faking its type.
40
Žiga Seilnacht71436f02007-03-14 12:24:09 +000041- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
42 name.
43
Georg Brandl5240d742007-03-13 20:46:32 +000044- Patch #1444529: the builtin compile() now accepts keyword arguments.
45
Georg Brandl7b9c5552007-03-12 14:30:05 +000046- Bug #1678647: write a newline after printing an exception in any
47 case, even when converting the value to a string failed.
48
Georg Brandl871f1bc2007-03-12 13:17:36 +000049- The dir() function has been extended to call the __dir__() method on
50 its argument, if it exists. If not, it will work like before. This allows
51 customizing the output of dir() in the presence of a __getattr__().
52
Collin Winter276887b2007-03-12 16:11:39 +000053- Patch #922167: Python no longer segfaults when faced with infinitely
54 self-recursive reload() calls (as reported by bug #742342).
55
Žiga Seilnacht89032082007-03-11 15:54:54 +000056- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
57
Collin Wintere38051d2007-03-09 20:33:07 +000058- Patch #1491866: change the complex() constructor to allow parthensized
59 forms. This means complex(repr(x)) now works instead of raising a
60 ValueError.
61
Georg Brandlaa2321b2007-03-07 00:40:28 +000062- Patch #703779: unset __file__ in __main__ after running a file. This
63 makes the filenames the warning module prints much more sensible when
64 a PYTHONSTARTUP file is used.
65
Georg Brandl49aafc92007-03-07 00:34:46 +000066- Variant of patch #697613: don't exit the interpreter on a SystemExit
67 exception if the -i command line option or PYTHONINSPECT environment
68 variable is given, but break into the interactive interpreter just like
69 on other exceptions or normal program exit.
70
Georg Brandl00cd8182007-03-06 18:41:12 +000071- Patch #1638879: don't accept strings with embedded NUL bytes in long().
72
Georg Brandl098cd692007-03-06 12:17:50 +000073- Bug #1674503: close the file opened by execfile() in an error condition.
74
Georg Brandl0fca97a2007-03-05 22:28:08 +000075- Patch #1674228: when assigning a slice (old-style), check for the
76 sq_ass_slice instead of the sq_slice slot.
77
Neal Norwitz88516a62007-02-26 22:41:45 +000078- When printing an unraisable error, don't print exceptions. before the name.
79 This duplicates the behavior whening normally printing exceptions.
80
Martin v. Löwisfd963262007-02-09 12:19:32 +000081- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
82
Brett Cannon129bd522007-01-30 21:34:36 +000083- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
84 catch a string exception raises DeprecationWarning.
85
Brett Cannonf5bee302007-01-23 23:21:22 +000086- Bug #1377858: Fix the segfaulting of the interpreter when an object created
87 a weakref on itself during a __del__ call for new-style classes (classic
88 classes still have the bug).
89
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000090- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
91 frame's thread state.
92
Thomas Wouters6ed19652007-01-23 13:50:49 +000093- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
94
Martin v. Löwis4885e7d2007-01-19 06:42:22 +000095- Bug #1637022: Prefix AST symbols with _Py_.
96
Neal Norwitz72cd02c2007-01-05 05:25:22 +000097- Prevent seg fault on shutdown which could occur if an object
98 raised a warning.
99
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000100- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
101 to avoid relying on atexit.
102
Raymond Hettinger94547f72006-12-20 06:42:06 +0000103- Bug #1590891: random.randrange don't return correct value for big number
104
Georg Brandl283a1352006-11-19 08:48:30 +0000105- Patch #1586791: Better exception messages for some operations on strings,
106 tuples and lists.

113
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000114- Bug #1576657: when setting a KeyError for a tuple key, make sure that
115 the tuple isn't used as the "exception arguments tuple".
116
Neal Norwitz21997af2006-10-28 21:19:07 +0000117- Bug #1565514, SystemError not raised on too many nested blocks.
118
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000119- Bug #1576174: WindowsError now displays the windows error code
120 again, no longer the posix error code.
121
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000122- Patch #1549049: Support long values in structmember, issue warnings
123 if the assigned value for structmember fields gets truncated.
124
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000125- Update the peephole optimizer to remove more dead code (jumps after returns)
126 and inline unconditional jumps to returns.
127
Georg Brandl2c1375c2006-10-12 11:27:59 +0000128- Bug #1545497: when given an explicit base, int() did ignore NULs
129 embedded in the string to convert.
130
Georg Brandl846f73a2006-10-08 07:11:54 +0000131- Bug #1569998: break inside a try statement (outside a loop) is now
132 recognized and rejected.
133
Armin Rigo7ccbca92006-10-04 12:17:45 +0000134- list.pop(x) accepts any object x following the __index__ protocol.
135
136- Fix some leftovers from the conversion from int to Py_ssize_t
137 (relevant to strings and sequences of more than 2**31 items).
138
139- A number of places, including integer negation and absolute value,
140 were fixed to not rely on undefined behaviour of the C compiler
141 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000142
Georg Brandl3267d282006-09-30 09:03:42 +0000143- Bug #1566800: make sure that EnvironmentError can be called with any

159
Brett Cannon9adeab72006-09-20 18:34:28 +0000160- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
161 allows calling unicode() on exceptions classes directly to succeed.
162
Georg Brandlec6c2df2006-09-11 09:38:35 +0000163- Make _PyGILState_NoteThreadState() static, it was not used anywhere

165
Georg Brandl4e933132006-09-06 20:05:58 +0000166- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
167 Also make sure that every exception class has __module__ set to
168 'exceptions'.

171 imports (if not in package and if beyond toplevel package).
172
Tim Petersc10c9d02006-09-05 02:18:09 +0000173- Overflow checking code in integer division ran afoul of new gcc
174 optimizations. Changed to be more standard-conforming.
175

181 head is the original string if sep was not found.
182
Neal Norwitzdac090d2006-09-05 03:53:08 +0000183- Bug #1520864: unpacking singleton tuples in list comprehensions and
184 generator expressions (x for x, in ... ) works again. Fixing this problem
185 required changing the .pyc magic number. This means that .pyc files
186 generated before 2.5c2 will be regenerated.
187
Neal Norwitzca460d92006-09-06 06:28:06 +0000188- with and as are now keywords.

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000192- Add new requirements for metaclasses. 1) If type or a subclass of type
193 occurs in __bases__, it must occur before any non-type bases, e.g.
194 before regular classes. 2) If you assign to __bases__, you may not
195 change the metaclass. Many more illegal assignments to __bases__
196 are now checked and raise TypeErrors. This changed fixed at least
197 one known crash.
198
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +0000199Library

307
Georg Brandl9caadf82007-03-08 18:37:31 +0000308- unittest now verifies more of its assumptions. In particular, TestCase
309 and TestSuite subclasses (not instances) are no longer accepted in
310 TestSuite.addTest(). This should cause no incompatibility since it

Guido van Rossumc69ac252006-08-10 18:09:25 +0000805What's New in Python 2.5 release candidate 1?
806=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000807
Anthony Baxterb4096662006-08-16 03:42:26 +0000808*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000809
810Core and builtins
811-----------------
812
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000813- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000814 compared equal or unequal to a string and a UnicodeDecodeError
815 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000816
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000817 Instead, the equal (==) and unequal (!=) comparison operators will
818 now issue a UnicodeWarning and interpret the two objects as
819 unequal. The UnicodeWarning can be filtered as desired using
820 the warning framework, e.g. silenced completely, turned into an
821 exception, logged, etc.
822
823 Note that compare operators other than equal and unequal will still
824 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000825
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000826- Fix segfault when doing string formatting on subclasses of long.
827
828- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
829 with new-style classes.
830
831- Fix bug related to __len__ functions returning negative values with
832 classic classes.
833
834- Patch #1538606, Fix __index__() clipping. There were some problems
835 discovered with the API and how integers that didn't fit into Py_ssize_t
836 were handled. This patch attempts to provide enough alternatives
837 to effectively use __index__.
838
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000839- Bug #1536021: __hash__ may now return long int; the final hash
840 value is obtained by invoking hash on the long int.
841
Thomas Hellerab1049c2006-08-08 17:37:00 +0000842- Bug #1536786: buffer comparison could emit a RuntimeWarning.
843
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000844- Bug #1535165: fixed a segfault in input() and raw_input() when
845 sys.stdin is closed.
846
Thomas Heller74d36f02006-08-04 18:17:40 +0000847- On Windows, the PyErr_Warn function is now exported from
848 the Python dll again.
849
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000850- Bug #1191458: tracing over for loops now produces a line event
851 on each iteration. Fixing this problem required changing the .pyc
852 magic number. This means that .pyc files generated before 2.5c1
853 will be regenerated.
854
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000855- Bug #1333982: string/number constants were inappropriately stored
856 in the byte code and co_consts even if they were not used, ie
857 immediately popped off the stack.
858
Georg Brandle9462c72006-08-04 18:03:37 +0000859- Fixed a reference-counting problem in property().

862Library
863-------
864
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000865- Fix a bug in the ``compiler`` package that caused invalid code to be
866 generated for generator expressions.
867
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000868- The distutils version has been changed to 2.5.0. The change to
869 keep it programmatically in sync with the Python version running
870 the code (introduced in 2.5b3) has been reverted. It will continue
871 to be maintained manually as static string literal.
872
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000873- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000874 and this cannot be converted to the required C type, an exception is
875 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000876 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000877
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000878- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000879 an exception.
880
Tim Petersc10c9d02006-09-05 02:18:09 +0000881- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000882 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000883 workarounds for clocks with low resolution, to stop the code yielding
884 duplicate UUIDs.
885
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000886- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
887 before raising SystemExit, allowing IDLE to honor quit() and exit().
888
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000889- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

892 file correctly even on Windows.
893
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000894- logging's atexit hook now runs even if the rest of the module has
895 already been cleaned up.
896

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000899- Bug #1531405, format_exception no longer raises an exception if
900 str(exception) raised an exception.
901
Neil Schemenauer06ded092006-08-04 16:20:30 +0000902- Fix a bug in the ``compiler`` package that caused invalid code to be

912 raises the correct exceptions.
913
Thomas Heller1ce433e2006-08-14 16:20:04 +0000914- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
915 '-no-stack-protector' compiler flag for OpenBSD has been removed.
916
Thomas Heller86720042006-08-14 11:17:48 +0000917- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
918 uses the _as_parameter_ attribute when objects are passed to foreign
919 function calls. The ctypes version number was changed to 1.0.1.
920
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000921- Bug #1530559, struct.pack raises TypeError where it used to convert.

961
Tim Peters4643c2f2006-08-10 22:45:34 +0000962- Bug #1069160. Internal correctness changes were made to
963 ``PyThreadState_SetAsyncExc()``. A test case was added, and
964 the documentation was changed to state that the return value
965 is always 1 (normal) or 0 (if the specified thread wasn't found).

973Core and builtins
974-----------------
975
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000976- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000977 returned a long (see PEP 353).
978
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000979- Bug #1515471: string.replace() accepts character buffers again.
980
Neal Norwitz07aadb12006-07-30 06:55:48 +0000981- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
982 This provides the proper warning for struct.pack().
983 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
984
Neal Norwitz0d62a062006-07-30 06:53:31 +0000985- Patch #1531113: Fix augmented assignment with yield expressions.
986 Also fix a SystemError when trying to assign to yield expressions.
987
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000988- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
989 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
990 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
991 excessive filesystem operations during imports.
992
Tim Petersbc24eee2006-07-27 01:14:53 +0000993- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
994 operations on signed longs that are formally undefined by C.
995 Unfortunately, at least one compiler now cares about that, so complicated
996 the code to make that compiler happy again.
997
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000998- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
999
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001000- Patch #1232023: Stop including current directory in search
1001 path on Windows.
1002
Neal Norwitze1fdb322006-07-21 05:32:28 +00001003- Fix some potential crashes found with failmalloc.
1004
Neal Norwitze7563102006-07-17 01:00:16 +00001005- Fix warnings reported by Klocwork's static analysis tool.
1006
Neal Norwitz84be93b2006-07-16 01:50:38 +00001007- Bug #1512814, Fix incorrect lineno's when code within a function
1008 had more than 255 blank lines.
1009
Georg Brandl9dceedb2006-07-12 15:31:17 +00001010- Patch #1521179: Python now accepts the standard options ``--help`` and
1011 ``--version`` as well as ``/?`` on Windows.
1012
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001013- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001014 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001015 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001016
Tim Peters112aad32006-07-19 00:03:19 +00001017- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001018 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001019 new ``sys._current_frames()`` returns a dictionary with one entry,
1020 mapping the faux "thread id" 0 to the current frame.
1021
Ronald Oussoren3075e162006-07-25 20:28:55 +00001022- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001023

Neal Norwitza1f10902006-07-12 07:28:29 +00001025Library
1026-------
1027
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001028- Correction of patch #1455898: In the mbcs decoder, set final=False
1029 for stream decoder, but final=True for the decode function.
1030
Georg Brandl07fec3a2006-08-01 18:49:24 +00001031- os.urandom no longer masks unrelated exceptions like SystemExit or
1032 KeyboardInterrupt.
1033
Tim Peters4643c2f2006-08-10 22:45:34 +00001034- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001035 shutil.copytree on Windows
1036
Georg Brandle34ac7c2006-07-30 11:07:23 +00001037- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1038 refers to file descriptors, not file objects.
1039
Tim Petersc10c9d02006-09-05 02:18:09 +00001040- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001041 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001042 #1513611, and probably others.
1043
Georg Brandledd9b0d2006-07-29 09:33:26 +00001044- Bug #1441397: The compiler module now recognizes module and function
1045 docstrings correctly as it did in Python 2.4.
1046
Tim Peters6f681472006-07-27 23:44:37 +00001047- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1048 lost that tests are sorted by name before being run. This rarely
1049 matters for well-written tests, but can create baffling symptoms if
1050 side effects from one test to the next affect outcomes. ``DocTestFinder``
1051 has been changed to sort the list of tests it returns.
1052
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001053- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001054 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001055
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001056- Bug #978833: Really close underlying socket in _socketobject.close.
1057
Georg Brandl8c036cc2006-08-20 13:15:39 +00001058- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1059 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001060
Georg Brandlcf0c1722006-07-26 07:23:32 +00001061- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1062 to recursive calls and call it with the failing package name.
1063
Martin v. Löwis0b483032006-07-25 09:53:12 +00001064- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1065
Georg Brandlc13c34c2006-07-24 14:09:56 +00001066- Patch #1515343: Fix printing of deprecated string exceptions with a
1067 value in the traceback module.
1068
Greg Ward48fae7a2006-07-23 16:05:51 +00001069- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1070
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001071- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1072
Brett Cannoncaebe222006-07-18 04:41:36 +00001073- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1074 argument tuple. For arguments where zero is illegal, the value is forced to
1075 the minimum value that is correct. This is to support an undocumented but
1076 common way people used to fill in inconsequential information in the time
1077 tuple pre-2.4.
1078
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001079- Patch #1220874: Update the binhex module for Mach-O.
1080
Barry Warsawb110bad2006-07-21 14:51:07 +00001081- The email package has improved RFC 2231 support, specifically for
1082 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1083 (name*0=<blah>) parameter continuations. This may change the types of
1084 values returned from email.message.Message.get_param() and friends.
1085 Specifically in some cases where non-encoded continuations were used,
1086 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1087 will just return the string (since non-encoded continuations don't have
1088 charset and language parts).
1089
1090 Also, whereas % values were decoded in all parameter continuations, they are
1091 now only decoded in encoded parameter parts.
1092
Ronald Oussoren3075e162006-07-25 20:28:55 +00001093- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1094
1095- Bug #1517996: IDLE now longer shows the default Tk menu when a
1096 path browser, class browser or debugger is the frontmost window on MacOS X
1097
Barry Warsaw00decd72006-07-27 23:43:15 +00001098- Patch #1520294: Support for getset and member descriptors in types.py,
1099 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1100 of an object against these built-in types and more importantly, for getting
1101 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitz9b0ca792006-08-02 06:46:21 +00001107- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1108 a socket operation on a socket with a timeout, the exception will be
1109 caught correctly. Previously, the exception was not caught.
1110
Thomas Heller1393d6a2006-07-28 21:43:20 +00001111- Patch #1529514: The _ctypes extension is now compiled on more
1112 openbsd target platforms.
1113
Tim Peters9cab5932006-07-28 00:30:00 +00001114- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1115 a memory leak, affecting pickles and deep copies.
1116
Tim Petersbc24eee2006-07-27 01:14:53 +00001117- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1119
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001120- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1121
Thomas Hellerce049a02006-07-14 17:51:14 +00001122- Patch #1521817: Index range checking on ctypes arrays containing
1123 exactly one element enabled again. This allows iterating over these
1124 arrays, without the need to check the array size before.
1125
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001126- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001127 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001128 /dev/null in certain cases; this is now fixed.
1129
Thomas Heller47d7a062006-07-12 08:43:47 +00001130- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1131 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001132
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001133- Because of a misspelled preprocessor symbol, ctypes was always
1134 compiled without thread support; this is now fixed.
1135
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001136- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1137 methods now allow their database parameter to be None as the
1138 sleepycat API allows.
1139
Matt Flemingec926502006-07-28 11:27:27 +00001140- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1141 bluetooth API compared with Linux and FreeBSD.
1142
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001143Tests
1144-----
1145
1146- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1147 how long the test file should take to play. Now accepts taking 2.93 secs
1148 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1149
Georg Brandl4793aa32006-07-28 18:31:39 +00001150- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1151 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1152 run via ``regrtest.py``. Now they do.

1162- PythonLauncher now works correctly when the path to the script contains
1163 characters that are treated specially by the shell (such as quotes).
1164
1165- Bug #1527397: PythonLauncher now launches scripts with the working directory
1166 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001167 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001168 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001179- Bug #1441486: The literal representation of -(sys.maxint - 1)
1180 again evaluates to a int object, not a long.
1181
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001182- Bug #1501934: The scope of global variables that are locally assigned
1183 using augmented assignment is now correctly determined.
1184
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001185- Bug #927248: Recursive method-wrapper objects can now safely
1186 be released.
1187
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001188- Bug #1417699: Reject locale-specific decimal point in float()
1189 and atof().
1190
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001191- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1192 omit a default "error" argument for NULL pointer. This allows
1193 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001194
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001195- Bug #1519018: 'as' is now validated properly in import statements.
1196
Neal Norwitz28746ab2006-07-09 22:14:42 +00001197- On 64 bit systems, int literals that use less than 64 bits are
1198 now ints rather than longs.
1199
Neal Norwitzed657552006-07-10 00:04:44 +00001200- Bug #1512814, Fix incorrect lineno's when code at module scope
1201 started after line 256.
1202
Tim Peters32a83612006-07-10 21:08:24 +00001203- New function ``sys._current_frames()`` returns a dict mapping thread
1204 id to topmost thread stack frame. This is for expert use, and is
1205 especially useful for debugging application deadlocks. The functionality
1206 was previously available in Fazal Majid's ``threadframe`` extension
1207 module, but it wasn't possible to do this in a wholly threadsafe way from
1208 an extension.

1214 VS 2003.
1215
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001216- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1217
Tim Peters32a83612006-07-10 21:08:24 +00001218- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001219 environment variable to be set in order to the SDK environment
1220 for finding the compiler, include files, etc.
1221
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001222- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1223
Nick Coghlan2d792252006-07-06 13:47:18 +00001224- warnings.py now ignores ImportWarning by default
1225
Thomas Woutersadd19112006-07-05 11:03:49 +00001226- string.Template() now correctly handles tuple-values. Previously,
1227 multi-value tuples would raise an exception and single-value tuples would
1228 be treated as the value they contain, instead.
1229
Martin v. Löwisede77f52006-07-03 13:01:35 +00001230- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1231 even if some data are received.
1232
Martin v. Löwis45482392006-07-03 12:28:58 +00001233- Bug #1267547: Put proper recursive setup.py call into the

1237 degrees and radians.
1238
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001239- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001240 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001241
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001242- Bug #1514703: Only setup canvas window in turtle when the canvas
1243 is created.
1244
Martin v. Löwis7596e832006-07-01 15:33:37 +00001245- Bug #1513223: .close() of a _socketobj now releases the underlying
1246 socket again, which then gets closed as it becomes unreferenced.
1247
Fred Drake10497c82006-06-29 02:57:48 +00001248- Bug #1504333: Make sgmllib support angle brackets in quoted
1249 attribute values.
1250
1251- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1252 sgmllib ('[' and ']' were not accepted).
1253
Georg Brandl1be63af2006-06-28 20:23:25 +00001254- Fix a bug in the turtle module's end_fill function.
1255
Brett Cannon53ab5b72006-06-22 16:49:14 +00001256- Bug #1510580: The 'warnings' module improperly required that a Warning
1257 category be either a types.ClassType and a subclass of Warning. The proper
1258 check is just that it is a subclass with Warning as the documentation states.
1259
Georg Brandlad29e632006-06-21 17:45:17 +00001260- The compiler module now correctly compiles the new try-except-finally
1261 statement (bug #1509132).
1262
Neal Norwitz60373cd2006-06-22 06:30:50 +00001263- The wsgiref package is now installed properly on Unix.
1264
Vinay Sajip28e57612006-07-01 10:45:20 +00001265- A bug was fixed in logging.config.fileConfig() which caused a crash on
1266 shutdown when fileConfig() was called multiple times.
1267
Gerhard Häring762fbd32006-07-02 17:48:30 +00001268- The sqlite3 module did cut off data from the SQLite database at the first
1269 null character before sending it to a custom converter. This has been fixed
1270 now.
1271
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001272Extension Modules
1273-----------------
1274
Tim Peters112aad32006-07-19 00:03:19 +00001275- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1276 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1277 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001278
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001279- Assigning None to pointer type fields in ctypes structures possible
1280 overwrote the wrong fields, this is fixed now.
1281
1282- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1283 on non-Windows platforms.
1284
1285- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1286 integer or long, without range checking.
1287
1288- Patch #1517790: It is now possible to use custom objects in the ctypes
1289 foreign function argtypes sequence as long as they provide a from_param
1290 method, no longer is it required that the object is a ctypes type.
1291
1292- The '_ctypes' extension module now works when Python is configured
1293 with the --without-threads option.
1294
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001295- Bug #1513646: os.access on Windows now correctly determines write
1296 access, again.
1297
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001298- Bug #1512695: cPickle.loads could crash if it was interrupted with
1299 a KeyboardInterrupt.
1300
Neal Norwitza12aa882006-07-06 06:45:08 +00001301- Bug #1296433: parsing XML with a non-default encoding and
1302 a CharacterDataHandler could crash the interpreter in pyexpat.
1303
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001304- Patch #1516912: improve Modules support for OpenVMS.

1308
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001309- Automate Windows build process for the Win64 SSL module.
1310
Tim Peters32a83612006-07-10 21:08:24 +00001311- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001312 Previously, the slight difference could cause compilation errors of the
1313 'zlib' module on systems with more than one version of zlib.
1314
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001315- The MSI compileall step was fixed to also support a TARGETDIR
1316 with spaces in it.
1317
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001318- Bug #1517388: sqlite3.dll is now installed on Windows independent
1319 of Tcl/Tk.
1320
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001321- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001322 trying to be installed even though it's empty.

1334 documentation for the warnings module.
1335
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001336- Patch #1509163: MS Toolkit Compiler no longer available.

Georg Brandlad29e632006-06-21 17:45:17 +00001342================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001343
Anthony Baxterd1136802006-06-19 12:04:15 +00001344*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001345
1346Core and builtins
1347-----------------
1348
Georg Brandla56b9152006-06-19 06:35:54 +00001349- Patch #1507676: Error messages returned by invalid abstract object operations
1350 (such as iterating over an integer) have been improved and now include the
1351 type of the offending object to help with debugging.
1352
Brett Cannonea3912b2006-06-13 21:46:41 +00001353- Bug #992017: A classic class that defined a __coerce__() method that returned
1354 its arguments swapped would infinitely recurse and segfault the interpreter.
1355
Neal Norwitz909eb122006-06-12 02:13:21 +00001356- Fix the socket tests so they can be run concurrently.
1357
Neal Norwitzb9845e72006-06-12 02:11:18 +00001358- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001359 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001360
Brett Cannon22565aa2006-06-09 22:31:23 +00001361- Bug #532646: object.__call__() will continue looking for the __call__
1362 attribute on objects until one without one is found. This leads to recursion
1363 when you take a class and set its __call__ attribute to an instance of the
1364 class. Originally fixed for classic classes, but this fix is for new-style.
1365 Removes the infinite_rec_3 crasher.
1366
Georg Brandl24250812006-06-09 18:45:48 +00001367- The string and unicode methods startswith() and endswith() now accept
1368 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1369
Brett Cannonde3b0522006-06-08 17:00:45 +00001370- Buffer objects, at the C level, never used the char buffer
1371 implementation even when the char buffer for the wrapped object was
1372 explicitly requested (originally returned the read or write buffer).
1373 Now a TypeError is raised if the char buffer is not present but is
1374 requested.
1375
Georg Brandlddbaa662006-06-04 21:56:52 +00001376- Patch #1346214: Statements like "if 0: suite" are now again optimized
1377 away like they were in Python 2.4.
1378
Georg Brandlb7c8f542006-05-27 12:30:25 +00001379- Builtin exceptions are now full-blown new-style classes instead of
1380 instances pretending to be classes, which speeds up exception handling
1381 by about 80% in comparison to 2.5a2.
1382
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001383- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1384 Unicode 4.1.
1385
Georg Brandlf4ef1162006-05-26 18:03:31 +00001386- Patch #921466: sys.path_importer_cache is now used to cache valid and
1387 invalid file paths for the built-in import machinery which leads to
1388 fewer open calls on startup.
1389
Tim Peters696cf432006-05-24 21:10:40 +00001390- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1391 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1392 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1393 the number of input digits (it was and remains linear-time for bases
1394 2, 4, 8, 16 and 32).
1395
Tim Petersb713ec22006-05-23 18:45:30 +00001396- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1397 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1398 an integer close to ``sys.maxint``. This was repaired by patch
1399 #1335972, which also gives a nice speedup.
1400
Richard Jonescebbefc2006-05-23 18:28:17 +00001401- Patch #1337051: reduced size of frame objects.
1402
1403- PyErr_NewException now accepts a tuple of base classes as its
1404 "base" parameter.
1405
Richard Jones7c88dcc2006-05-23 10:37:38 +00001406- Patch #876206: function call speedup by retaining allocated frame
1407 objects.
1408
Georg Brandl7b90e162006-05-18 07:01:27 +00001409- Bug #1462152: file() now checks more thoroughly for invalid mode
1410 strings and removes a possible "U" before passing the mode to the
1411 C library function.
1412
Neal Norwitz1004a532006-05-15 07:17:23 +00001413- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1414
Neal Norwitz373f0a72006-05-15 07:04:36 +00001415- Bug #1487966: Fix SystemError with conditional expression in assignment
1416
Martin v. Löwis879768d2006-05-11 13:28:43 +00001417- WindowsError now has two error code attributes: errno, which carries
1418 the error values from errno.h, and winerror, which carries the error
1419 values from winerror.h. Previous versions put the winerror.h values
1420 (from GetLastError()) into the errno attribute.
1421
Martin v. Löwis77736712006-05-04 05:51:03 +00001422- Patch #1475845: Raise IndentationError for unexpected indent.
1423
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001424- Patch #1479181: split open() and file() from being aliases for each other.
1425
Tim Peters44bd9862006-06-01 13:49:23 +00001426- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1427 methods were always silently ignored by dictionaries when comparing keys.
1428 They are now passed through (except when using the C API function
1429 ``PyDict_GetItem()``, whose semantics did not change).
1430
1431- Bug #1456209: In some obscure cases it was possible for a class with a
1432 custom ``__eq__()`` method to confuse dict internals when class instances
1433 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1434 No, you don't have any code that did this ;-)

1437-----------------
1438
Trent Mick960a3f82006-06-28 20:30:41 +00001439- Bug #1295808: expat symbols should be namespaced in pyexpat
1440
1441- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1442
Brett Cannon6ee7d012006-06-08 16:23:04 +00001443- Change binascii.hexlify to accept a read-only buffer instead of only a char
1444 buffer and actually follow its documentation.
1445
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001446- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1447
Nick Coghlanc649ec52006-05-29 12:43:05 +00001448- Patch #1478788 (modified version): The functional extension module has
1449 been renamed to _functools and a functools Python wrapper module added.
1450 This provides a home for additional function related utilities that are
1451 not specifically about functional programming. See PEP 309.
1452
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001453- Patch #1493701: performance enhancements for struct module.
1454
Georg Brandl378d5922006-05-17 14:26:50 +00001455- Patch #1490224: time.altzone is now set correctly on Cygwin.
1456
Georg Brandl8d3342b2006-05-16 07:38:27 +00001457- Patch #1435422: zlib's compress and decompress objects now have a
1458 copy() method.
1459
Andrew MacIntyre92913322006-06-13 15:04:24 +00001460- Patch #1454481: thread stack size is now tunable at runtime for thread
1461 enabled builds on Windows and systems with Posix threads support.
1462
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001463- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1464 (up to the system limit of 32K characters).
1465
1466- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1467 As a result, these functions now raise WindowsError instead of OSError.
1468
Tim Peters7a822da2006-05-25 21:50:17 +00001469- ``time.clock()`` on Win64 should use the high-performance Windows
1470 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1471 Windows platforms).
1472
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001473- Calling Tk_Init twice is refused if the first call failed as that
1474 may deadlock.
1475
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001476- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1477 accept it without potentially using an uninitialized pointer.
1478
1479- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1480 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1485
Gregory P. Smith372b5832006-06-05 18:48:21 +00001486- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1487 parameter is supplied. [SF pybsddb bug #1477863]
1488
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001489- bsddb: the __len__ method of a DB object has been fixed to return correct
1490 results. It could previously incorrectly return 0 in some cases.
1491 Fixes SF bug 1493322 (pybsddb bug 1184012).
1492
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001493- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1494 aborts the db transaction safely when a modifier callback fails.
1495 Fixes SF python patch/bug #1408584.
1496
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001497- bsddb: multithreaded DB access using the simple bsddb module interface

1531
Tim Peters43898b42006-06-14 04:09:25 +00001532- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1533 guarantee that adjacent triples in the return list always describe
1534 non-adjacent blocks. Previously, a pair of matching blocks could end
1535 up being described by multiple adjacent triples that formed a partition
1536 of the matching pair.

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001546- The wsgiref package has been added to the standard library.
1547
Nick Coghlan676725d2006-06-08 13:54:49 +00001548- The functions update_wrapper() and wraps() have been added to the functools
1549 module. These make it easier to copy relevant metadata from the original
1550 function when writing wrapper functions.
1551
Tim Petersd6a9eef2006-06-05 01:48:21 +00001552- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1553 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001554
Martin v. Löwis3f767792006-06-04 19:36:28 +00001555- Patch #1359618: Speed up charmap encoder by using a trie structure
1556 for lookup.
1557
Tim Petersd609b1a2006-06-02 23:22:51 +00001558- The functions in the ``pprint`` module now sort dictionaries by key
1559 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1560 if and only if its display required more than one line, although that
1561 wasn't documented. The new behavior increases predictability; e.g.,
1562 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

Georg Brandlb89316f2006-05-17 15:51:16 +00001574- Patch #1180296: Two new functions were added to the locale module:
1575 format_string() to get the effect of "format % items" but locale-aware,
1576 and currency() to format a monetary number with currency sign.

1585 stdout arguments, making it possible to redirect input and output
1586 for remote debugging.
1587
1588- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1589 a couple of issues, notably handling of long file names using the
1590 GNU LONGNAME extension.
1591
1592- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1593 new flag when ``name`` is already the name of an option flag.
1594
1595- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1596 package.

1640-----------------
1641
Thomas Heller1b046642006-04-18 18:51:06 +00001642- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1643 by converting these apis from macros into exported functions again:
1644
1645 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1646 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1647 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1649 PyRun_String Py_CompileString
1650
Martin v. Löwis45294a92006-04-18 06:24:08 +00001651- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1652
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001653- All uses of PyStructSequence_InitType have been changed to initialize
1654 the type objects only once, even if the interpreter is initialized
1655 multiple times.
1656
Neal Norwitz61546162006-04-14 05:20:28 +00001657- Bug #1454485, array.array('u') could crash the interpreter. This was
1658 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1659 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1660
1661- Py_UNICODE is unsigned. It was always documented as unsigned, but
1662 due to a bug had a signed value in previous versions.
1663
Tim Peters3a5e8b12006-04-11 01:44:07 +00001664- Patch #837242: ``id()`` of any Python object always gives a positive
1665 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1666 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001667 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001668 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001669
Tim Peters3a5e8b12006-04-11 01:44:07 +00001670 def __hash__(self):
1671 return id(self) # WRONG
1672
1673 because a hash result must be a (short) Python int but it was always
1674 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001675 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001676 was always usable as a hash value before this patch. That's no longer
1677 necessarily so.
1678
1679- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001680 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001681 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001682 #1454844)
1683
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001684- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1685 involving generators that have paused outside of any ``try`` or ``with``
1686 blocks. (In 2.5a1, a paused generator that was part of a reference
1687 cycle could not be garbage collected, regardless of whether it was
1688 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001720- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

1722 or exception is ignored).
1723
Nick Coghlanda2268f2006-04-24 04:37:15 +00001724- Fixed contextlib.nested to cope with exceptions being raised and
1725 caught inside exit handlers.
1726
Greg Wardab05edc2006-04-23 03:47:58 +00001727- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1728 hex, octal, or binary; add ``append_const`` action; keep going if
1729 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1730 added ``epilog`` for better help generation).
1731
Tim Peters21fbd572006-04-21 21:18:10 +00001732- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1733 called from a thread spawned as a side effect of importing a module.
1734
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001735- The pydoc module now supports documenting packages contained in
1736 .zip or .egg files.
1737
1738- The pkgutil module now has several new utility functions, such
1739 as ``walk_packages()`` to support working with packages that are either
1740 in the filesystem or zip files.
1741
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001742- The mailbox module can now modify and delete messages from
1743 mailboxes, in addition to simply reading them. Thanks to Gregory
1744 K. Johnson for writing the code, and to the 2005 Google Summer of
1745 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001746
Tim Petersc7605f22006-04-17 21:12:33 +00001747- The ``__del__`` method of class ``local`` in module ``_threading_local``
1748 returned before accomplishing any of its intended cleanup.
1749
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001750- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001781- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001782
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001783- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1784 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001785 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001786 CXX from --with-cxx-main, see description in README.
1787
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001788- Patch #1429775: Link extension modules with the shared libpython.
1789
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001790- Fixed a libffi build problem on MIPS systems.
1791
Tim Peters8931ff12006-05-13 23:28:20 +00001792- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1793 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1794 and "%zu" for unsigned integers of type ``size_t``.
1795
Anthony Baxter51bcb682006-04-05 14:51:42 +00001796Tests
1797-----
1798
Nick Coghlanda2268f2006-04-24 04:37:15 +00001799- test_contextlib now checks contextlib.nested can cope with exceptions
1800 being raised and caught inside exit handlers.
1801
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001802- test_cmd_line now checks operation of the -m and -c command switches
1803
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001804- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1805 it separately and by hand. It also wasn't cleaning up its changes to
1806 the current Decimal context.
1807
Thomas Woutersabd08882006-04-26 15:53:30 +00001808- regrtest.py now has a -M option to run tests that test the new limits of
1809 containers, on 64-bit architectures. Running these tests is only sensible
1810 on 64-bit machines with more than two gigabytes of memory. The argument
1811 passed is the maximum amount of memory for the tests to use.
1812
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001813Tools
1814-----
1815
1816- Added the Python benchmark suite pybench to the Tools/ directory;
1817 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001818
Anthony Baxter51bcb682006-04-05 14:51:42 +00001819Documentation
1820-------------
1821
Tim Petersb06d28c2006-05-12 01:57:59 +00001822- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1823
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001824- PEP 343: Added Context Types section to the library reference
1825 and attempted to bring other PEP 343 related documentation into
1826 line with the implementation and/or python-dev discussions.
1827
Tim Peters8dc73d22006-04-24 02:03:16 +00001828- Bug #1337990: clarified that ``doctest`` does not support examples
1829 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001832What's New in Python 2.5 alpha 1?
1833=================================
1834
Anthony Baxterebed3f62006-04-03 15:03:44 +00001835*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001836
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001837Core and builtins
1838-----------------
1839
Nick Coghlan43832302006-04-23 17:04:07 +00001840- PEP 338: -m command line switch now delegates to runpy.run_module
1841 allowing it to support modules in packages and zipfiles
1842
Martin v. Löwisc661b882006-04-20 04:54:23 +00001843- On Windows, .DLL is not an accepted file name extension for
1844 extension modules anymore; extensions are only found if they
1845 end in .PYD.
1846
Martin v. Löwisea62d252006-04-03 10:56:49 +00001847- Bug #1421664: sys.stderr.encoding is now set to the same value as
1848 sys.stdout.encoding.
1849
Neal Norwitz92e212f2006-04-03 04:48:37 +00001850- __import__ accepts keyword arguments.
1851
Georg Brandlccadf842006-03-31 18:54:53 +00001852- Patch #1460496: round() now accepts keyword arguments.
1853
Anthony Baxter262c00a2006-03-30 10:53:17 +00001854- Fixed bug #1459029 - unicode reprs were double-escaped.
1855
Hye-Shik Changd478f342006-03-23 12:32:36 +00001856- Patch #1396919: The system scope threads are reenabled on FreeBSD
1857 5.4 and later versions.
1858
Neal Norwitze98ccf62006-03-23 05:39:47 +00001859- Bug #1115379: Compiling a Unicode string with an encoding declaration
1860 now gives a SyntaxError.
1861
Georg Brandlabd1ff82006-03-18 07:59:59 +00001862- Previously, Python code had no easy way to access the contents of a
1863 cell object. Now, a ``cell_contents`` attribute has been added
1864 (closes patch #1170323).
1865
Tim Peterscf79aac2006-03-16 01:14:46 +00001866- Patch #1123430: Python's small-object allocator now returns an arena to
1867 the system ``free()`` when all memory within an arena becomes unused
1868 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1869 freed. Some applications will see a drop in virtual memory size now,
1870 especially long-running applications that, from time to time, temporarily
1871 use a large number of small objects. Note that when Python returns an
1872 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001873 platform C library will in turn return that memory to the operating system.
1874 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001875 appears to be effective at least on Microsoft C and gcc-based systems.
1876 Thanks to Evan Jones for hard work and patience.
1877
Georg Brandl533ff6f2006-03-08 18:09:27 +00001878- Patch #1434038: property() now uses the getter's docstring if there is
1879 no "doc" argument given. This makes it possible to legitimately use
1880 property() as a decorator to produce a read-only property.
1881
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001882- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1883 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1884 of requiring an int or long in slicing and a few other contexts, enabling
1885 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1886
Neal Norwitz995acdf2006-03-07 05:01:00 +00001887- Fixed various bugs reported by Coverity's Prevent tool.
1888
Brett Cannonbf364092006-03-01 04:25:17 +00001889- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1890 new exception base class, BaseException, which has a new message attribute.
1891 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1892 Raising a string exception now raises a DeprecationWarning.
1893
Thomas Woutersfb609f42006-02-28 16:37:25 +00001894- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1895 explicitly relative, using 'from .module import name' to mean 'from the same
1896 package as this module is in. Imports without dots still default to the
1897 old relative-then-absolute, unless 'from __future__ import
1898 absolute_import' is used.
1899
Brett Cannona7446e32006-02-27 23:39:10 +00001900- Properly check if 'warnings' raises an exception (usually when a filter set
1901 to "error" is triggered) when raising a warning for raising string
1902 exceptions.
1903
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001904- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001905 The name was removed from Include/code.h.
1906
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001907- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001908
Guido van Rossum1968ad32006-02-25 22:38:04 +00001909- Patch 1433928:
1910 - The copy module now "copies" function objects (as atomic objects).
1911 - dict.__getitem__ now looks for a __missing__ hook before raising
1912 KeyError.
1913
Tim Peters84ef21c2006-02-28 20:39:06 +00001914- PEP 343: with statement implemented. Needs ``from __future__ import
1915 with_statement``. Use of 'with' as a variable will generate a warning.
1916 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001917 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001918 The following objects have __context__ methods:
1919 - The built-in file type.
1920 - The thread.LockType type.
1921 - The following types defined by the threading module:
1922 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1923 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001924
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001925- Fix the encodings package codec search function to only search
1926 inside its own package. Fixes problem reported in patch #1433198.
1927
1928 Note: Codec packages should implement and register their own
1929 codec search function. PEP 100 has the details.
1930
Tim Peters9ea89d22006-06-04 03:26:02 +00001931- PEP 353: Using ``Py_ssize_t`` as the index type.
1932
1933- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1934 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1935 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1936 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1937 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001938
Neal Norwitzfc76d632006-01-10 06:03:13 +00001939- Patch #1400181, fix unicode string formatting to not use the locale.
1940 This is how string objects work. u'%f' could use , instead of .
1941 for the decimal point. Now both strings and unicode always use periods.
1942
Neal Norwitz671b9e32006-01-09 07:07:12 +00001943- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1944 configure would break checking curses.h.
1945
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001946- Bug #959576: The pwd module is now builtin. This allows Python to be
1947 built on UNIX platforms without $HOME set.
1948
Neal Norwitzc10978f2005-12-19 06:07:16 +00001949- Bug #1072182, fix some potential problems if characters are signed.
1950
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001951- Bug #889500, fix line number on SyntaxWarning for global declarations.
1952
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001953- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1954
Neal Norwitze7214a12005-12-18 05:03:17 +00001955- Support for converting hex strings to floats no longer works.
1956 This was not portable. float('0x3') now raises a ValueError.
1957
Barry Warsaw2a38a862005-12-18 01:27:35 +00001958- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001959 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001960 is now displayed in interactive prompt banner.
1961
Georg Brandlfa166682005-12-17 21:45:17 +00001962- Implementation of PEP 341 - Unification of try/except and try/finally.
1963 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001964 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001965
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001966- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1967 now encodes backslash correctly.
1968
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001969- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1970
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001971- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001972 and long longs.
1973
Neal Norwitz67715f02005-11-09 06:59:35 +00001974- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001975 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001976 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001977
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001978- Replaced most Unicode charmap codecs with new ones using the
1979 new Unicode translate string feature in the builtin charmap
1980 codec; the codecs were created from the mapping tables available
1981 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1982 encodings now include a mapping for the Apple logo)
1983
Tim Peterse3547fd2005-12-16 23:13:57 +00001984- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001985
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001986- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001987
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001988- A new AST parser implementation was completed. The abstract
1989 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001990 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001991
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001992- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001993 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1994
Neal Norwitz708e51a2005-10-03 04:48:15 +00001995- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1996
Neal Norwitz11bd1192005-10-03 00:54:56 +00001997- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1998 Provide a warning when a directory is passed on the command line.
1999
Neal Norwitz40d37812005-10-02 01:48:49 +00002000- Fix segfault with invalid coding.
2001
2002- SF bug #772896: unknown encoding results in MemoryError.
2003
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002004- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002005 supported a __len__() method which evaluated to False when the iterator
2006 was empty.
2007
Guido van Rossum630db602005-09-20 18:49:54 +00002008- On 64-bit platforms, when __len__() returns a value that cannot be
2009 represented as a C int, raise OverflowError.
2010
Skip Montanarof8948ca2005-09-19 03:54:46 +00002011- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002012 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002013
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002014- SF bug #893549: parsing keyword arguments was broken with a few format
2015 codes.
2016
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002017- Changes donated by Elemental Security to make it work on AIX 5.3
2018 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2019 bug #105470: test_pwd fails on 64bit system (Opteron).
2020
Guido van Rossum539c6622005-09-14 17:49:54 +00002021- Changes donated by Elemental Security to make it work on HP-UX 11 on
2022 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2023
Georg Brandl4550b8d2005-08-26 06:43:52 +00002024- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002025 (fixes bug #1119418).
2026
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002027- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2028
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002029- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2030 exceptions that cause a function to exit.
2031
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002032- The implementation of set() and frozenset() was revised to use its
2033 own internal data structure. Memory consumption is reduced by 1/3
2034 and there are modest speed-ups as well. The API is unchanged.
2035
Tim Petersde7990b2005-07-17 23:45:23 +00002036- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2037
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002038- SF bug #1229429: PyObject_CallMethod failed to decrement some
2039 reference counts in some error exit cases.
2040
Tim Petersecc6e6a2005-07-10 22:30:55 +00002041- SF bug #1185883: Python's small-object memory allocator took over
2042 a block managed by the platform C library whenever a realloc specified
2043 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002044 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002045 portable way to copy data from the C-managed block into Python's
2046 small-object space without risking a memory fault. Python's small-object
2047 realloc now leaves such blocks under the control of the platform C
2048 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002050- SF bug #1232517: An overflow error was not detected properly when
2051 attempting to convert a large float to an int in os.utime().
2052
Raymond Hettinger3296e692005-06-29 23:29:56 +00002053- SF bug #1224347: hex longs now print with lowercase letters just
2054 like their int counterparts.
2055
Michael W. Hudson188d4362005-06-20 16:52:57 +00002056- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2057 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2058 interpreter states; back out that fix and do a better job (see
2059 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2060 for a longer write-up of the problem).
2061
Michael W. Hudsondf888462005-06-03 14:41:55 +00002062- SF patch #1180995: marshal now uses a binary format by default when
2063 serializing floats.
2064
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002065- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2066 the routines that promise to produce IEEE 754 binary representations
2067 of floats now simply copy bytes around.
2068
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002069- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2070 278.
2071
Brett Cannonc3647ac2005-04-26 03:45:26 +00002072- patch #1109424: int, long, float, complex, and unicode now check for the
2073 proper magic slot for type conversions when subclassed. Previously the
2074 magic slot was ignored during conversion. Semantics now match the way
2075 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002076 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002077 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002078 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002079
Barry Warsawc8d907c2005-04-19 23:43:40 +00002080- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2081 NULL, now raise an AttributeError when attempting to set or delete the
2082 attribute. Previously a TypeError was raised, but this was inconsistent
2083 with the equivalent pure-Python implementation.
2084
Michael W. Hudson774479c2005-04-18 08:46:17 +00002085- It is now safe to call PyGILState_Release() before
2086 PyEval_InitThreads() (note that if there is reason to believe there
2087 are multiple threads around you still must call PyEval_InitThreads()
2088 before using the Python API; this fix is for extension modules that
2089 have no way of knowing if Python is multi-threaded yet).
2090
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002091- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2092 disabled caused a crash.
2093
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002094- Bug #1165306: instancemethod_new allowed the creation of a method
2095 with im_class == im_self == NULL, which caused a crash when called.
2096
Tim Petersecc6e6a2005-07-10 22:30:55 +00002097- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002098 fixes the crash seen in bug #1165761
2099
Raymond Hettinger96229b12005-03-11 06:49:40 +00002100- Added two new builtins, any() and all().
2101
Brett Cannon409d8f22005-03-05 06:47:57 +00002102- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002103 (e.g., ``class C(): pass`` is no longer a syntax error).
2104 Patch #1176012 added support to the 'parser' module and 'compiler' package
2105 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002106
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002107- Patch #1115086: Support PY_LONGLONG in structmember.
2108
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002109- Bug #1155938: new style classes did not check that __init__() was
2110 returning None.
2111
Tim Petersecc6e6a2005-07-10 22:30:55 +00002112- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002113 ('\') with a specific error message.
2114
Martin v. Löwisff232d72005-03-03 09:24:38 +00002115- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2116
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002117- Bug #1124295: the __name__ attribute of file objects was
2118 inadvertently made inaccessible in restricted mode.
2119
Tim Petersecc6e6a2005-07-10 22:30:55 +00002120- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002121 an ferror() call.
2122
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002123- min() and max() now support key= arguments with the same meaning as in
2124 list.sort().
2125
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002126- The peephole optimizer now performs simple constant folding in expressions:
2127 (2+3) --> (5).
2128
Raymond Hettingera422c342005-01-11 03:03:27 +00002129- set and frozenset objects can now be marshalled. SF #1098985.
2130
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002131- Bug #1077106: Poor argument checking could cause memory corruption
2132 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002133
Jeremy Hyltonab630502005-02-04 18:44:06 +00002134- The parser did not complain about future statements in illegal
2135 positions. It once again reports a syntax error if a future
2136 statement occurs after anything other than a doc string.
2137
Neil Schemenauercf52c072005-08-12 17:34:58 +00002138- Change the %s format specifier for str objects so that it returns a
2139 unicode instance if the argument is not an instance of basestring and
2140 calling __str__ on the argument returns a unicode instance.
2141
Tim Petersf4e69282006-02-27 17:15:31 +00002142- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2143 current thread state when the auto-GIL-state machinery knows about
2144 it (since the thread state is being deleted, continuing to remember it
2145 can't help, but can hurt if another thread happens to get created with
2146 the same thread id).
2147

2165
2166- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2167
2168- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002169 is deprecated. The undocumented re.engine variable no longer exists.

2173
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002174- The unicodedata module was updated to the 4.1 version of the Unicode
2175 database. The 3.2 version is still available as unicodedata.db_3_2_0
2176 for applications that require this specific version (such as IDNA).
2177
Neal Norwitzb62c4332006-03-04 18:35:47 +00002178- The timing module is no longer built by default. It was deprecated

Martin v. Löwis14694662006-02-03 12:54:16 +00002200- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2201 are reported, the limit on path name lengths is removed, and stat reports
2202 WindowsError now (instead of OSError).
2203

2279 the request code argument, which results in more C-like behaviour
2280 for large or negative values.
2281
Tim Petersecc6e6a2005-07-10 22:30:55 +00002282- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2323 args tuple returned by __reduce__().
2324
Raymond Hettingerb2594052004-12-05 09:25:51 +00002325- itertools.islice() now accepts None for the start and step arguments.
2326 This allows islice() to work more readily with slices:

Tim Peters112aad32006-07-19 00:03:19 +00002337
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002338- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2339 been renamed to have only a single underscore prefix. This was done to
2340 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002341
Nick Coghlan43832302006-04-23 17:04:07 +00002342- PEP 338: new module runpy defines a run_module function to support
2343 executing modules which provide access to source code or a code object
2344 via the PEP 302 import mechanisms.
2345
Anthony Baxter93f5b932006-04-03 08:05:07 +00002346- The email module's parsedate_tz function now sets the daylight savings

2354 in attribute values.
2355
Anthony Baxterc51ee692006-04-01 00:57:31 +00002356- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002357 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002358 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002359 module will not be built.
2360
Tim Petersc17976e2006-04-01 00:26:53 +00002361- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2362 aren't officially supported here, and trying to use them will probably
2363 raise an exception some day. But dicts have been allowed, and "mostly
2364 worked", so support for them won't go away without warning.
2365
Georg Brandl338ef7d2006-03-31 18:42:16 +00002366- Bug #1445068: getpass.getpass() can now be given an explicit stream
2367 argument to specify where to write the prompt.
2368
Georg Brandl22ec80b2006-03-31 18:25:44 +00002369- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2378 to make it easier to monitor when daemon threads have completed
2379 processing all enqueued tasks. Patch #1455676.
2380
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002381- popen2.Popen objects now preserve the command in a .cmd attribute.

2384
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002385- email 4.0 package now integrated. This is largely the same as the email 3.0
2386 package that was included in Python 2.3, except that PEP 8 module names are
2387 now used (e.g. mail.message instead of email.Message). The MIME classes
2388 have been moved to a subpackage (e.g. email.mime.text instead of
2389 email.MIMEText). The old names are still supported for now. Several
2390 deprecated Message methods have been removed and lots of bugs have been
2391 fixed. More details can be found in the email package documentation.
2392
Walter Dörwald40108c92006-03-27 08:15:44 +00002393- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2394 (a subclass of tuple) that provides incremental decoders and encoders
2395 (a way to use stateful codecs without the stream API). Python functions
2396 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2397 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2398 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002399
Walter Dörwald067db482006-03-15 22:17:27 +00002400- Patch #1359365: Calling next() on a closed StringIO.String object raises
2401 a ValueError instead of a StopIteration now (like file and cString.String do).
2402 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2403 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002404
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002405- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002453 specifications, raises IOErrors when proxies for unsupported protocols
2454 are defined, and uses the https proxy on https redirections.

2478 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2479 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2480 Ronald L. Rivest offered this advice for Python:
2481
2482 "The consensus of researchers in this area (at least as
2483 expressed at the NIST Hash Function Workshop 10/31/05),
2484 is that SHA-256 is a good choice for the time being, but
2485 that research should continue, and other alternatives may
2486 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002487
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002488- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002572
Georg Brandl2f210b62005-06-26 22:09:06 +00002573- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2574
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002575- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2576 error messages.
2577
Georg Brandl379f99d2005-06-26 21:09:38 +00002578- Bug #1108948: Cookie.py produced invalid JavaScript code.
2579
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002580- The tokenize module now detects and reports indentation errors.
2581 Bug #1224621.
2582
Raymond Hettinger68c04532005-06-10 11:05:19 +00002583- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002584 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002585 the generate_tokens() function now accepts a callable argument that
2586 terminates by raising StopIteration.
2587
Georg Brandl9166e1a2005-06-04 09:20:03 +00002588- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2589
Georg Brandl268e61c2005-06-03 14:28:50 +00002590- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2591 component of the path.
2592
Skip Montanaro174dd222005-05-14 20:54:16 +00002593- Patch #1120353: The xmlrpclib module provides better, more transparent,
2594 support for datetime.{datetime,date,time} objects. With use_datetime set
2595 to True, applications shouldn't have to fiddle with the DateTime wrapper
2596 class at all.
2597
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002598- distutils.commands.upload was added to support uploading distribution
2599 files to PyPI.
2600
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002601- distutils.commands.register now encodes the data as UTF-8 before posting
2602 them to PyPI.
2603
Raymond Hettinger267b8682005-03-27 10:47:39 +00002604- decimal operator and comparison methods now return NotImplemented
2605 instead of raising a TypeError when interacting with other types. This
2606 allows other classes to implement __radd__ style methods and have them
2607 work as expected.
2608
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002609- Bug #1163325: Decimal infinities failed to hash. Attempting to
2610 hash a NaN raised an InvalidOperation instead of a TypeError.
2611
Tim Petersecc6e6a2005-07-10 22:30:55 +00002612- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002613 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2614
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002615- Patch #1043890: Add extractall method to tarfile.

2618 to build.
2619
Martin v. Löwis637431b2005-03-03 23:12:42 +00002620- Patch #1103407: Properly deal with tarfile iterators when untarring
2621 symbolic links on Windows.

2644
Raymond Hettingerbab41432005-02-05 01:31:19 +00002645- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2646
Guido van Rossumd0641422005-02-03 15:01:24 +00002647- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2648 disables recursive traversal through instance attributes, which can
2649 be exploited in various ways.
2650
Tim Peterse3547fd2005-12-16 23:13:57 +00002651- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002652 flags on the HTTP listening socket.
2653
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002654- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2655 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2656
Fred Drakefbdeaad2006-07-29 16:56:15 +00002657- Patches #893642, #1039083: add allow_none, encoding arguments to
2658 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002659
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002660- Bug #1110478: Revert os.environ.update to do putenv again.
2661
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002662- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2663
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002664- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2665
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002666- Enhancements to the csv module:
2667
2668 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002669 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002670 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002671 + Dialect parameter parsing has been re-implemented to improve error
2672 reporting.
2673 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2674 dictates.
2675 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002676 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002677 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002678 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2679 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002680 + reader now allows \r characters to be quoted (previously it only allowed
2681 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002682 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002683 + Dialect classes passed to the module are no longer instantiated by
2684 the module before being parsed (the former validation scheme required
2685 this, but the mechanism was unreliable).
2686 + The dialect registry now contains instances of the internal
2687 C-coded dialect type, rather than references to python objects.
2688 + the internal c-coded dialect type is now immutable.
2689 + register_dialect now accepts the same keyword dialect specifications
2690 as the reader and writer, allowing the user to register dialects
2691 without first creating a dialect class.
2692 + a configurable limit to the size of parsed fields has been added -
2693 previously, an unmatched quote character could result in the entire
2694 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002695 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002696 the parser field size limit (returning the former limit). The initial
2697 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002698 + A line_num attribute has been added to the reader object, which tracks
2699 the number of lines read from the source iterator. This is not
2700 the same as the number of records returned, as records can span
2701 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002702 + reader and writer objects were not being registered with the cyclic-GC.
2703 This has been fixed.
2704
Brett Cannone6539c42005-01-08 02:43:53 +00002705- _DummyThread objects in the threading module now delete self.__block that is
2706 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2707 lock primitives tend to be limited in number and thus should not be wasted on
2708 a _DummyThread object. Fixes bug #1089632.
2709
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002710- The imghdr module now detects Exif files.
2711
Raymond Hettinger6065d322004-12-20 23:51:53 +00002712- StringIO.truncate() now correctly adjusts the size attribute.
2713 (Bug #951915).
2714
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002715- locale.py now uses an updated locale alias table (built using
2716 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2717 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002718 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002719
Raymond Hettinger3557f422004-12-07 12:02:02 +00002720- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2721
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002722- the pickle module no longer accepts the deprecated None option in the
2723 args tuple returned by __reduce__().
2724
Brett Cannon84667c02004-12-07 03:25:18 +00002725- optparse now optionally imports gettext. This allows its use in setup.py.
2726
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002727- the pickle module no longer uses the deprecated bin parameter.
2728
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002729- the shelve module no longer uses the deprecated binary parameter.
2730
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002731- the pstats module no longer uses the deprecated ignore() method.
2732
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002733- the filecmp module no longer uses the deprecated use_statcache argument.
2734
Raymond Hettinger664347b2004-12-04 21:21:53 +00002735- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2736 extended or overridden by subclasses. Formerly, the subclassed method would
2737 be ignored by the rest of the module. (Bug #1078905).
2738
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002739- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002740 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002741
Walter Dörwald36733692004-12-22 12:50:50 +00002742- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2743 once when a size argument is given. This prevents a buffer overflow in the
2744 tokenizer with very long source lines.
2745
Barry Warsaw538561e2006-01-01 21:48:54 +00002746- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2747 immediately after creating the object, without any intervening
2748 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002749
Skip Montanaro05885812005-01-16 20:48:27 +00002750- The reconvert.quote function can now emit triple-quoted strings. The
2751 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002752
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002753- ``UserString.MutableString`` now supports negative indices in
2754 ``__setitem__`` and ``__delitem__``
2755
Greg Ward40407942005-03-05 02:53:17 +00002756- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2757 correctly.
2758
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002759- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2760 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2761 character even if the user has passed a size parameter to get a proper
2762 line ending. Remove the special handling of a "\r\n" that has been split
2763 between two lines.
2764
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002765- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2766 about illegal code points. The codec now supports PEP 293 style error
2767 handlers.
2768
Walter Dörwald78a78b02005-09-01 12:04:29 +00002769- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002770 from the input stream, so that the output is a byte string in the correct
2771 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002772
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002773- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2774 considering it exactly like a '*'.
2775
Walter Dörwald007f8df2005-10-09 19:42:27 +00002776- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2777 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002778
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002779- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2780
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002781- Patch #1413711: Certain patterns of differences were making difflib
2782 touch the recursion limit.
2783
Walter Dörwald58917a62006-03-31 15:26:22 +00002784- Bug #947906: An object oriented interface has been added to the calendar
2785 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002786 called as a script (e.g. via ``python -mcalendar``). Localized month and
2787 weekday names can be ouput (even if an exotic encoding is used) using
2788 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002789

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002804- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2805 The zlib module is now builtin on Windows.
2806
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002807- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2808
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002809- Bug #1189330: configure did not correctly determine the necessary
2810 value of LINKCC if python was built with GCC 4.0.
2811
Trent Mick8321b422005-07-26 02:29:21 +00002812- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2813 vulnerability in zlib 1.2.1 and 1.2.2.
2814
Brett Cannon08cd5982005-04-24 22:26:38 +00002815- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2816 flags that change binary compatibility. Changes were also made to
2817 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002818 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002819
Bob Ippolitoed233462005-03-29 13:47:59 +00002820- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2821 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2822 no longer exists). This configure patch makes things right.
2823
Martin v. Löwise2713be2005-03-08 15:03:08 +00002824- Bug #1158607: Build with --disable-unicode again.
2825
Brett Cannon46d96232005-02-16 00:07:19 +00002826- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2827 defined. Discovered as a result of not being able to build on OS X.
2828
Brett Cannon516592f2004-12-07 00:42:59 +00002829- setup.py now uses the directories specified in LDFLAGS using the -L option
2830 and in CPPFLAGS using the -I option for adding library and include
2831 directories, respectively, for compiling extension modules against. This has
2832 led to the core being compiled using the values in CPPFLAGS. It also removes
2833 the need for the special-casing of both DarwinPorts and Fink for darwin since
2834 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2835 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2836 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00002838- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2839 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2840 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2841 Closes bug #1096244. Thanks Gregory Bond.

2845
Tim Petersc9d78aa2006-03-26 23:27:58 +00002846- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2847 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2848 is obtained via the ``PyObject_`` family, it must be released via the
2849 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2850 always been officially true, but when Python's small-object allocator was
2851 introduced, an attempt was made to cater to a few extension modules
2852 discovered at the time that obtained memory via ``PyObject_New`` but
2853 released it via ``PyMem_DEL``. It's years later, and if such code still
2854 exists it will fail now (probably with segfaults, but calling wrong
2855 low-level memory management functions can yield many symptoms).
2856
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002857- Added a C API for set and frozenset objects.
2858

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002861- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2862 mapping argument now. This string is used as a mapping table. Byte values
2863 greater than the length of the string and 0xFFFE are treated as undefined
2864 mappings.
