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
Guido van Rossum234b1ff2007-03-23 19:39:01 +000025 warning later). Also, type.__init__() insists on the same signature
26 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000027
Georg Brandl2b869942007-03-17 16:08:45 +000028- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
29 to complex using its __complex__() method before falling back to the
30 __float__() method. Therefore, the functions in the cmath module now
31 can operate on objects that define a __complex__() method.
32
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000033- Patch #1623563: allow __class__ assignment for classes with __slots__.
34 The old and the new class are still required to have the same slot names.
35
Collin Winter77c67bd2007-03-16 04:11:30 +000036- Patch #1642547: Fix an error/crash when encountering syntax errors in
37 complex if statements.
38
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000039- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
40 is called with an object that is faking its type.
41
Žiga Seilnacht71436f02007-03-14 12:24:09 +000042- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
43 name.
44
Georg Brandl5240d742007-03-13 20:46:32 +000045- Patch #1444529: the builtin compile() now accepts keyword arguments.
46
Georg Brandl7b9c5552007-03-12 14:30:05 +000047- Bug #1678647: write a newline after printing an exception in any
48 case, even when converting the value to a string failed.
49
Georg Brandl871f1bc2007-03-12 13:17:36 +000050- The dir() function has been extended to call the __dir__() method on
51 its argument, if it exists. If not, it will work like before. This allows
52 customizing the output of dir() in the presence of a __getattr__().
53
Collin Winter276887b2007-03-12 16:11:39 +000054- Patch #922167: Python no longer segfaults when faced with infinitely
55 self-recursive reload() calls (as reported by bug #742342).
56
Žiga Seilnacht89032082007-03-11 15:54:54 +000057- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
58
Collin Wintere38051d2007-03-09 20:33:07 +000059- Patch #1491866: change the complex() constructor to allow parthensized
60 forms. This means complex(repr(x)) now works instead of raising a
61 ValueError.
62
Georg Brandlaa2321b2007-03-07 00:40:28 +000063- Patch #703779: unset __file__ in __main__ after running a file. This
64 makes the filenames the warning module prints much more sensible when
65 a PYTHONSTARTUP file is used.
66
Georg Brandl49aafc92007-03-07 00:34:46 +000067- Variant of patch #697613: don't exit the interpreter on a SystemExit
68 exception if the -i command line option or PYTHONINSPECT environment
69 variable is given, but break into the interactive interpreter just like
70 on other exceptions or normal program exit.
71
Georg Brandl00cd8182007-03-06 18:41:12 +000072- Patch #1638879: don't accept strings with embedded NUL bytes in long().
73
Georg Brandl098cd692007-03-06 12:17:50 +000074- Bug #1674503: close the file opened by execfile() in an error condition.
75
Georg Brandl0fca97a2007-03-05 22:28:08 +000076- Patch #1674228: when assigning a slice (old-style), check for the
77 sq_ass_slice instead of the sq_slice slot.
78
Neal Norwitz88516a62007-02-26 22:41:45 +000079- When printing an unraisable error, don't print exceptions. before the name.
80 This duplicates the behavior whening normally printing exceptions.
81
Martin v. Löwisfd963262007-02-09 12:19:32 +000082- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
83
Brett Cannon129bd522007-01-30 21:34:36 +000084- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
85 catch a string exception raises DeprecationWarning.
86
Brett Cannonf5bee302007-01-23 23:21:22 +000087- Bug #1377858: Fix the segfaulting of the interpreter when an object created
88 a weakref on itself during a __del__ call for new-style classes (classic
89 classes still have the bug).
90
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000091- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
92 frame's thread state.
93
Thomas Wouters6ed19652007-01-23 13:50:49 +000094- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py

97
Neal Norwitz72cd02c2007-01-05 05:25:22 +000098- Prevent seg fault on shutdown which could occur if an object
99 raised a warning.
100
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000101- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
102 to avoid relying on atexit.
103
Raymond Hettinger94547f72006-12-20 06:42:06 +0000104- Bug #1590891: random.randrange don't return correct value for big number
105
Georg Brandl283a1352006-11-19 08:48:30 +0000106- Patch #1586791: Better exception messages for some operations on strings,

114
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000115- Bug #1576657: when setting a KeyError for a tuple key, make sure that
116 the tuple isn't used as the "exception arguments tuple".
117
Neal Norwitz21997af2006-10-28 21:19:07 +0000118- Bug #1565514, SystemError not raised on too many nested blocks.
119
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000120- Bug #1576174: WindowsError now displays the windows error code
121 again, no longer the posix error code.
122
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000123- Patch #1549049: Support long values in structmember, issue warnings
124 if the assigned value for structmember fields gets truncated.
125
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000126- Update the peephole optimizer to remove more dead code (jumps after returns)
127 and inline unconditional jumps to returns.
128
Georg Brandl2c1375c2006-10-12 11:27:59 +0000129- Bug #1545497: when given an explicit base, int() did ignore NULs
130 embedded in the string to convert.
131
Georg Brandl846f73a2006-10-08 07:11:54 +0000132- Bug #1569998: break inside a try statement (outside a loop) is now
133 recognized and rejected.
134
Armin Rigo7ccbca92006-10-04 12:17:45 +0000135- list.pop(x) accepts any object x following the __index__ protocol.
136
137- Fix some leftovers from the conversion from int to Py_ssize_t
138 (relevant to strings and sequences of more than 2**31 items).
139
140- A number of places, including integer negation and absolute value,
141 were fixed to not rely on undefined behaviour of the C compiler
142 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000143
Georg Brandl3267d282006-09-30 09:03:42 +0000144- Bug #1566800: make sure that EnvironmentError can be called with any

154
Neal Norwitz3a230172006-09-22 08:18:10 +0000155- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

160
Brett Cannon9adeab72006-09-20 18:34:28 +0000161- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
162 allows calling unicode() on exceptions classes directly to succeed.
163
Georg Brandlec6c2df2006-09-11 09:38:35 +0000164- Make _PyGILState_NoteThreadState() static, it was not used anywhere

172 imports (if not in package and if beyond toplevel package).
173
Tim Petersc10c9d02006-09-05 02:18:09 +0000174- Overflow checking code in integer division ran afoul of new gcc
175 optimizations. Changed to be more standard-conforming.
176

182 head is the original string if sep was not found.
183
Neal Norwitzdac090d2006-09-05 03:53:08 +0000184- Bug #1520864: unpacking singleton tuples in list comprehensions and
185 generator expressions (x for x, in ... ) works again. Fixing this problem
186 required changing the .pyc magic number. This means that .pyc files
187 generated before 2.5c2 will be regenerated.
188
Neal Norwitzca460d92006-09-06 06:28:06 +0000189- with and as are now keywords.

Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +0000192
Jeremy Hyltoncca75402007-02-27 18:33:31 +0000193- Add new requirements for metaclasses. 1) If type or a subclass of type
194 occurs in __bases__, it must occur before any non-type bases, e.g.
195 before regular classes. 2) If you assign to __bases__, you may not
196 change the metaclass. Many more illegal assignments to __bases__
197 are now checked and raise TypeErrors. This changed fixed at least
198 one known crash.
199
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +0000200Library

229 GNOME or KDE browser, depending on whether there is a session of one
230 of those present. Also, it tries the Windows default browser before
231 trying Mozilla variants.
232
Collin Winter6f187742007-03-16 22:16:08 +0000233- Patch #1339796: add a relpath() function to os.path.

Georg Brandl9caadf82007-03-08 18:37:31 +0000319- unittest now verifies more of its assumptions. In particular, TestCase
320 and TestSuite subclasses (not instances) are no longer accepted in

Guido van Rossumc69ac252006-08-10 18:09:25 +0000829What's New in Python 2.5 release candidate 1?
830=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000831
Anthony Baxterb4096662006-08-16 03:42:26 +0000832*Release date: 17-AUG-2006*

834Core and builtins
835-----------------
836
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000837- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000838 compared equal or unequal to a string and a UnicodeDecodeError
839 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000840
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000841 Instead, the equal (==) and unequal (!=) comparison operators will
842 now issue a UnicodeWarning and interpret the two objects as
843 unequal. The UnicodeWarning can be filtered as desired using
844 the warning framework, e.g. silenced completely, turned into an
845 exception, logged, etc.
846
847 Note that compare operators other than equal and unequal will still
848 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000849
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000850- Fix segfault when doing string formatting on subclasses of long.
851
852- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
853 with new-style classes.
854
855- Fix bug related to __len__ functions returning negative values with
856 classic classes.
857
858- Patch #1538606, Fix __index__() clipping. There were some problems
859 discovered with the API and how integers that didn't fit into Py_ssize_t
860 were handled. This patch attempts to provide enough alternatives
861 to effectively use __index__.
862
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000863- Bug #1536021: __hash__ may now return long int; the final hash
864 value is obtained by invoking hash on the long int.
865
Thomas Hellerab1049c2006-08-08 17:37:00 +0000866- Bug #1536786: buffer comparison could emit a RuntimeWarning.

872 the Python dll again.
873
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000874- Bug #1191458: tracing over for loops now produces a line event
875 on each iteration. Fixing this problem required changing the .pyc
876 magic number. This means that .pyc files generated before 2.5c1
877 will be regenerated.
878
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000879- Bug #1333982: string/number constants were inappropriately stored
880 in the byte code and co_consts even if they were not used, ie
881 immediately popped off the stack.
882
Georg Brandle9462c72006-08-04 18:03:37 +0000883- Fixed a reference-counting problem in property().

890 generated for generator expressions.
891
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000892- The distutils version has been changed to 2.5.0. The change to
893 keep it programmatically in sync with the Python version running
894 the code (introduced in 2.5b3) has been reverted. It will continue
895 to be maintained manually as static string literal.
896
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000897- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000898 and this cannot be converted to the required C type, an exception is
899 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000900 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000901
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000902- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000903 an exception.
904
Tim Petersc10c9d02006-09-05 02:18:09 +0000905- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000906 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000907 workarounds for clocks with low resolution, to stop the code yielding
908 duplicate UUIDs.
909
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000910- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
911 before raising SystemExit, allowing IDLE to honor quit() and exit().
912
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000913- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
914
Georg Brandl7a1af772006-08-14 21:55:28 +0000915- Patch #1536071: trace.py should now find the full module name of a
916 file correctly even on Windows.
917
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000918- logging's atexit hook now runs even if the rest of the module has
919 already been cleaned up.
920
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000921- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000922
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000923- Bug #1531405, format_exception no longer raises an exception if
924 str(exception) raised an exception.
925
Neil Schemenauer06ded092006-08-04 16:20:30 +0000926- Fix a bug in the ``compiler`` package that caused invalid code to be
927 generated for nested functions.
928
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000929
930Extension Modules

932
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000933- Patch #1511317: don't crash on invalid hostname (alias) info.
934
Georg Brandl3335a7a2006-08-14 21:42:55 +0000935- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
936 raises the correct exceptions.
937
Thomas Heller1ce433e2006-08-14 16:20:04 +0000938- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
939 '-no-stack-protector' compiler flag for OpenBSD has been removed.
940
Thomas Heller86720042006-08-14 11:17:48 +0000941- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
942 uses the _as_parameter_ attribute when objects are passed to foreign
943 function calls. The ctypes version number was changed to 1.0.1.
944
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000945- Bug #1530559, struct.pack raises TypeError where it used to convert.
946 Passing float arguments to struct.pack when integers are expected
947 now triggers a DeprecationWarning.
948
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000949

959
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000960- test_threading now skips testing alternate thread stack sizes on
961 platforms that don't support changing thread stack size.
962
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000963

969
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000970Build
971-----
972
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000973- Bug #1535502, build _hashlib on Windows, and use masm assembler
974 code in OpenSSL.
975
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000976- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
977
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000978- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

Tim Peters4643c2f2006-08-10 22:45:34 +0000981C API
982-----
983
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000984- New API for Unicode rich comparisons: PyUnicode_RichCompare()
985
Tim Peters4643c2f2006-08-10 22:45:34 +0000986- Bug #1069160. Internal correctness changes were made to
987 ``PyThreadState_SetAsyncExc()``. A test case was added, and
988 the documentation was changed to state that the return value
989 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000992What's New in Python 2.5 beta 3?
993================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000994
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000995*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000996
997Core and builtins
998-----------------
999
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001000- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001001 returned a long (see PEP 353).
1002
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001003- Bug #1515471: string.replace() accepts character buffers again.
1004
Neal Norwitz07aadb12006-07-30 06:55:48 +00001005- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1006 This provides the proper warning for struct.pack().
1007 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1008
Neal Norwitz0d62a062006-07-30 06:53:31 +00001009- Patch #1531113: Fix augmented assignment with yield expressions.
1010 Also fix a SystemError when trying to assign to yield expressions.
1011
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001012- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1013 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1014 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1015 excessive filesystem operations during imports.
1016
Tim Petersbc24eee2006-07-27 01:14:53 +00001017- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1018 operations on signed longs that are formally undefined by C.
1019 Unfortunately, at least one compiler now cares about that, so complicated
1020 the code to make that compiler happy again.
1021
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001022- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1023
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001024- Patch #1232023: Stop including current directory in search
1025 path on Windows.
1026
Neal Norwitze1fdb322006-07-21 05:32:28 +00001027- Fix some potential crashes found with failmalloc.
1028
Neal Norwitze7563102006-07-17 01:00:16 +00001029- Fix warnings reported by Klocwork's static analysis tool.
1030
Neal Norwitz84be93b2006-07-16 01:50:38 +00001031- Bug #1512814, Fix incorrect lineno's when code within a function
1032 had more than 255 blank lines.
1033
Georg Brandl9dceedb2006-07-12 15:31:17 +00001034- Patch #1521179: Python now accepts the standard options ``--help`` and
1035 ``--version`` as well as ``/?`` on Windows.
1036
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001037- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001038 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001039 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001040
Tim Peters112aad32006-07-19 00:03:19 +00001041- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001042 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001043 new ``sys._current_frames()`` returns a dictionary with one entry,
1044 mapping the faux "thread id" 0 to the current frame.
1045
Ronald Oussoren3075e162006-07-25 20:28:55 +00001046- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001047

Neal Norwitza1f10902006-07-12 07:28:29 +00001049Library
1050-------
1051
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001052- Correction of patch #1455898: In the mbcs decoder, set final=False
1053 for stream decoder, but final=True for the decode function.
1054
Georg Brandl07fec3a2006-08-01 18:49:24 +00001055- os.urandom no longer masks unrelated exceptions like SystemExit or
1056 KeyboardInterrupt.
1057
Tim Peters4643c2f2006-08-10 22:45:34 +00001058- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001059 shutil.copytree on Windows
1060
Georg Brandle34ac7c2006-07-30 11:07:23 +00001061- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1062 refers to file descriptors, not file objects.
1063
Tim Petersc10c9d02006-09-05 02:18:09 +00001064- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001065 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001066 #1513611, and probably others.
1067
Georg Brandledd9b0d2006-07-29 09:33:26 +00001068- Bug #1441397: The compiler module now recognizes module and function
1069 docstrings correctly as it did in Python 2.4.
1070
Tim Peters6f681472006-07-27 23:44:37 +00001071- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1072 lost that tests are sorted by name before being run. This rarely
1073 matters for well-written tests, but can create baffling symptoms if
1074 side effects from one test to the next affect outcomes. ``DocTestFinder``
1075 has been changed to sort the list of tests it returns.
1076
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001077- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001078 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001079
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001080- Bug #978833: Really close underlying socket in _socketobject.close.
1081
Georg Brandl8c036cc2006-08-20 13:15:39 +00001082- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1083 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001084
Georg Brandlcf0c1722006-07-26 07:23:32 +00001085- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1086 to recursive calls and call it with the failing package name.
1087
Martin v. Löwis0b483032006-07-25 09:53:12 +00001088- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1089
Georg Brandlc13c34c2006-07-24 14:09:56 +00001090- Patch #1515343: Fix printing of deprecated string exceptions with a
1091 value in the traceback module.
1092
Greg Ward48fae7a2006-07-23 16:05:51 +00001093- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1094
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001095- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1096
Brett Cannoncaebe222006-07-18 04:41:36 +00001097- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1098 argument tuple. For arguments where zero is illegal, the value is forced to
1099 the minimum value that is correct. This is to support an undocumented but
1100 common way people used to fill in inconsequential information in the time
1101 tuple pre-2.4.
1102
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001103- Patch #1220874: Update the binhex module for Mach-O.
1104
Barry Warsawb110bad2006-07-21 14:51:07 +00001105- The email package has improved RFC 2231 support, specifically for
1106 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1107 (name*0=<blah>) parameter continuations. This may change the types of
1108 values returned from email.message.Message.get_param() and friends.
1109 Specifically in some cases where non-encoded continuations were used,
1110 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1111 will just return the string (since non-encoded continuations don't have
1112 charset and language parts).
1113
1114 Also, whereas % values were decoded in all parameter continuations, they are
1115 now only decoded in encoded parameter parts.
1116
Ronald Oussoren3075e162006-07-25 20:28:55 +00001117- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1118
1119- Bug #1517996: IDLE now longer shows the default Tk menu when a
1120 path browser, class browser or debugger is the frontmost window on MacOS X
1121
Barry Warsaw00decd72006-07-27 23:43:15 +00001122- Patch #1520294: Support for getset and member descriptors in types.py,
1123 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1124 of an object against these built-in types and more importantly, for getting
1125 their docstrings printed in the interactive interpreter's help() function.

1129-----------------
1130
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001131- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1132 a socket operation on a socket with a timeout, the exception will be
1133 caught correctly. Previously, the exception was not caught.
1134
Thomas Heller1393d6a2006-07-28 21:43:20 +00001135- Patch #1529514: The _ctypes extension is now compiled on more
1136 openbsd target platforms.
1137
Tim Peters9cab5932006-07-28 00:30:00 +00001138- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1139 a memory leak, affecting pickles and deep copies.
1140
Tim Petersbc24eee2006-07-27 01:14:53 +00001141- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001142 Paul Eggert.
1143

1145
Thomas Hellerce049a02006-07-14 17:51:14 +00001146- Patch #1521817: Index range checking on ctypes arrays containing
1147 exactly one element enabled again. This allows iterating over these
1148 arrays, without the need to check the array size before.
1149
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001150- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001151 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001152 /dev/null in certain cases; this is now fixed.
1153
Thomas Heller47d7a062006-07-12 08:43:47 +00001154- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1155 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001156
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001157- Because of a misspelled preprocessor symbol, ctypes was always
1158 compiled without thread support; this is now fixed.
1159
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001160- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1161 methods now allow their database parameter to be None as the
1162 sleepycat API allows.
1163
Matt Flemingec926502006-07-28 11:27:27 +00001164- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1165 bluetooth API compared with Linux and FreeBSD.
1166
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001167Tests
1168-----
1169
1170- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1171 how long the test file should take to play. Now accepts taking 2.93 secs
1172 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1173
Georg Brandl4793aa32006-07-28 18:31:39 +00001174- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1175 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1176 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001183Mac
1184---
1185
1186- PythonLauncher now works correctly when the path to the script contains
1187 characters that are treated specially by the shell (such as quotes).
1188
1189- Bug #1527397: PythonLauncher now launches scripts with the working directory
1190 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001191 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001192 expect.

1200Core and builtins
1201-----------------
1202
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001203- Bug #1441486: The literal representation of -(sys.maxint - 1)
1204 again evaluates to a int object, not a long.
1205
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001206- Bug #1501934: The scope of global variables that are locally assigned
1207 using augmented assignment is now correctly determined.
1208
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001209- Bug #927248: Recursive method-wrapper objects can now safely
1210 be released.
1211
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001212- Bug #1417699: Reject locale-specific decimal point in float()
1213 and atof().
1214
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001215- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1216 omit a default "error" argument for NULL pointer. This allows
1217 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001218
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001219- Bug #1519018: 'as' is now validated properly in import statements.
1220
Neal Norwitz28746ab2006-07-09 22:14:42 +00001221- On 64 bit systems, int literals that use less than 64 bits are
1222 now ints rather than longs.
1223
Neal Norwitzed657552006-07-10 00:04:44 +00001224- Bug #1512814, Fix incorrect lineno's when code at module scope
1225 started after line 256.
1226
Tim Peters32a83612006-07-10 21:08:24 +00001227- New function ``sys._current_frames()`` returns a dict mapping thread
1228 id to topmost thread stack frame. This is for expert use, and is
1229 especially useful for debugging application deadlocks. The functionality
1230 was previously available in Fazal Majid's ``threadframe`` extension
1231 module, but it wasn't possible to do this in a wholly threadsafe way from
1232 an extension.
1233

Martin v. Löwis77621582006-07-30 13:27:31 +00001237- Bug #1257728: Mention Cygwin in distutils error message about a missing
1238 VS 2003.
1239
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001240- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1241
Tim Peters32a83612006-07-10 21:08:24 +00001242- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001243 environment variable to be set in order to the SDK environment
1244 for finding the compiler, include files, etc.
1245
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001246- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1247
Nick Coghlan2d792252006-07-06 13:47:18 +00001248- warnings.py now ignores ImportWarning by default
1249
Thomas Woutersadd19112006-07-05 11:03:49 +00001250- string.Template() now correctly handles tuple-values. Previously,
1251 multi-value tuples would raise an exception and single-value tuples would
1252 be treated as the value they contain, instead.
1253
Martin v. Löwisede77f52006-07-03 13:01:35 +00001254- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1255 even if some data are received.
1256
Martin v. Löwis45482392006-07-03 12:28:58 +00001257- Bug #1267547: Put proper recursive setup.py call into the
1258 spec file generated by bdist_rpm.
1259
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001260- Bug #1514693: Update turtle's heading when switching between
1261 degrees and radians.
1262
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001263- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001264 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001265
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001266- Bug #1514703: Only setup canvas window in turtle when the canvas
1267 is created.
1268
Martin v. Löwis7596e832006-07-01 15:33:37 +00001269- Bug #1513223: .close() of a _socketobj now releases the underlying
1270 socket again, which then gets closed as it becomes unreferenced.

1273 attribute values.
1274
1275- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1276 sgmllib ('[' and ']' were not accepted).
1277
Georg Brandl1be63af2006-06-28 20:23:25 +00001278- Fix a bug in the turtle module's end_fill function.
1279
Brett Cannon53ab5b72006-06-22 16:49:14 +00001280- Bug #1510580: The 'warnings' module improperly required that a Warning
1281 category be either a types.ClassType and a subclass of Warning. The proper
1282 check is just that it is a subclass with Warning as the documentation states.
1283
Georg Brandlad29e632006-06-21 17:45:17 +00001284- The compiler module now correctly compiles the new try-except-finally
1285 statement (bug #1509132).
1286
Neal Norwitz60373cd2006-06-22 06:30:50 +00001287- The wsgiref package is now installed properly on Unix.
1288
Vinay Sajip28e57612006-07-01 10:45:20 +00001289- A bug was fixed in logging.config.fileConfig() which caused a crash on
1290 shutdown when fileConfig() was called multiple times.
1291
Gerhard Häring762fbd32006-07-02 17:48:30 +00001292- The sqlite3 module did cut off data from the SQLite database at the first
1293 null character before sending it to a custom converter. This has been fixed
1294 now.
1295
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001296Extension Modules
1297-----------------
1298
Tim Peters112aad32006-07-19 00:03:19 +00001299- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1300 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1301 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001302
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001303- Assigning None to pointer type fields in ctypes structures possible
1304 overwrote the wrong fields, this is fixed now.
1305
1306- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1307 on non-Windows platforms.
1308
1309- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1310 integer or long, without range checking.
1311
1312- Patch #1517790: It is now possible to use custom objects in the ctypes
1313 foreign function argtypes sequence as long as they provide a from_param
1314 method, no longer is it required that the object is a ctypes type.
1315
1316- The '_ctypes' extension module now works when Python is configured
1317 with the --without-threads option.
1318
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001319- Bug #1513646: os.access on Windows now correctly determines write
1320 access, again.
1321
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001322- Bug #1512695: cPickle.loads could crash if it was interrupted with
1323 a KeyboardInterrupt.
1324
Neal Norwitza12aa882006-07-06 06:45:08 +00001325- Bug #1296433: parsing XML with a non-default encoding and
1326 a CharacterDataHandler could crash the interpreter in pyexpat.
1327
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001328- Patch #1516912: improve Modules support for OpenVMS.
1329
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001330Build
1331-----
1332
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001333- Automate Windows build process for the Win64 SSL module.
1334
Tim Peters32a83612006-07-10 21:08:24 +00001335- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001336 Previously, the slight difference could cause compilation errors of the
1337 'zlib' module on systems with more than one version of zlib.
1338
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001339- The MSI compileall step was fixed to also support a TARGETDIR
1340 with spaces in it.
1341
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001342- Bug #1517388: sqlite3.dll is now installed on Windows independent
1343 of Tcl/Tk.
1344
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001345- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001346 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001348Tests
1349-----
1350
1351- Call os.waitpid() at the end of tests that spawn child processes in order
1352 to minimize resources (zombies).
1353
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001354Documentation
1355-------------
1356
Nick Coghlan2d792252006-07-06 13:47:18 +00001357- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1358 documentation for the warnings module.
1359
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001360- Patch #1509163: MS Toolkit Compiler no longer available.
1361
Neal Norwitz56640df2006-07-10 02:36:41 +00001362- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001367
Anthony Baxterd1136802006-06-19 12:04:15 +00001368*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001369
1370Core and builtins
1371-----------------
1372
Georg Brandla56b9152006-06-19 06:35:54 +00001373- Patch #1507676: Error messages returned by invalid abstract object operations
1374 (such as iterating over an integer) have been improved and now include the
1375 type of the offending object to help with debugging.
1376
Brett Cannonea3912b2006-06-13 21:46:41 +00001377- Bug #992017: A classic class that defined a __coerce__() method that returned
1378 its arguments swapped would infinitely recurse and segfault the interpreter.
1379
Neal Norwitz909eb122006-06-12 02:13:21 +00001380- Fix the socket tests so they can be run concurrently.
1381
Neal Norwitzb9845e72006-06-12 02:11:18 +00001382- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001383 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001384
Brett Cannon22565aa2006-06-09 22:31:23 +00001385- Bug #532646: object.__call__() will continue looking for the __call__
1386 attribute on objects until one without one is found. This leads to recursion
1387 when you take a class and set its __call__ attribute to an instance of the
1388 class. Originally fixed for classic classes, but this fix is for new-style.
1389 Removes the infinite_rec_3 crasher.
1390
Georg Brandl24250812006-06-09 18:45:48 +00001391- The string and unicode methods startswith() and endswith() now accept
1392 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1393
Brett Cannonde3b0522006-06-08 17:00:45 +00001394- Buffer objects, at the C level, never used the char buffer
1395 implementation even when the char buffer for the wrapped object was
1396 explicitly requested (originally returned the read or write buffer).
1397 Now a TypeError is raised if the char buffer is not present but is
1398 requested.
1399
Georg Brandlddbaa662006-06-04 21:56:52 +00001400- Patch #1346214: Statements like "if 0: suite" are now again optimized
1401 away like they were in Python 2.4.
1402
Georg Brandlb7c8f542006-05-27 12:30:25 +00001403- Builtin exceptions are now full-blown new-style classes instead of
1404 instances pretending to be classes, which speeds up exception handling
1405 by about 80% in comparison to 2.5a2.
1406
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001407- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1408 Unicode 4.1.
1409
Georg Brandlf4ef1162006-05-26 18:03:31 +00001410- Patch #921466: sys.path_importer_cache is now used to cache valid and
1411 invalid file paths for the built-in import machinery which leads to
1412 fewer open calls on startup.
1413
Tim Peters696cf432006-05-24 21:10:40 +00001414- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1415 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1416 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1417 the number of input digits (it was and remains linear-time for bases
1418 2, 4, 8, 16 and 32).
1419
Tim Petersb713ec22006-05-23 18:45:30 +00001420- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1421 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1422 an integer close to ``sys.maxint``. This was repaired by patch
1423 #1335972, which also gives a nice speedup.
1424
Richard Jonescebbefc2006-05-23 18:28:17 +00001425- Patch #1337051: reduced size of frame objects.
1426
1427- PyErr_NewException now accepts a tuple of base classes as its
1428 "base" parameter.
1429
Richard Jones7c88dcc2006-05-23 10:37:38 +00001430- Patch #876206: function call speedup by retaining allocated frame
1431 objects.
1432
Georg Brandl7b90e162006-05-18 07:01:27 +00001433- Bug #1462152: file() now checks more thoroughly for invalid mode
1434 strings and removes a possible "U" before passing the mode to the
1435 C library function.
1436
Neal Norwitz1004a532006-05-15 07:17:23 +00001437- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1438
Neal Norwitz373f0a72006-05-15 07:04:36 +00001439- Bug #1487966: Fix SystemError with conditional expression in assignment
1440
Martin v. Löwis879768d2006-05-11 13:28:43 +00001441- WindowsError now has two error code attributes: errno, which carries
1442 the error values from errno.h, and winerror, which carries the error
1443 values from winerror.h. Previous versions put the winerror.h values
1444 (from GetLastError()) into the errno attribute.
1445
Martin v. Löwis77736712006-05-04 05:51:03 +00001446- Patch #1475845: Raise IndentationError for unexpected indent.
1447
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001448- Patch #1479181: split open() and file() from being aliases for each other.
1449
Tim Peters44bd9862006-06-01 13:49:23 +00001450- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1451 methods were always silently ignored by dictionaries when comparing keys.
1452 They are now passed through (except when using the C API function
1453 ``PyDict_GetItem()``, whose semantics did not change).
1454
1455- Bug #1456209: In some obscure cases it was possible for a class with a
1456 custom ``__eq__()`` method to confuse dict internals when class instances
1457 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1458 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00001463- Bug #1295808: expat symbols should be namespaced in pyexpat
1464
1465- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1466
Brett Cannon6ee7d012006-06-08 16:23:04 +00001467- Change binascii.hexlify to accept a read-only buffer instead of only a char
1468 buffer and actually follow its documentation.
1469
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001470- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1471
Nick Coghlanc649ec52006-05-29 12:43:05 +00001472- Patch #1478788 (modified version): The functional extension module has
1473 been renamed to _functools and a functools Python wrapper module added.
1474 This provides a home for additional function related utilities that are
1475 not specifically about functional programming. See PEP 309.
1476
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001477- Patch #1493701: performance enhancements for struct module.
1478
Georg Brandl378d5922006-05-17 14:26:50 +00001479- Patch #1490224: time.altzone is now set correctly on Cygwin.
1480
Georg Brandl8d3342b2006-05-16 07:38:27 +00001481- Patch #1435422: zlib's compress and decompress objects now have a
1482 copy() method.
1483
Andrew MacIntyre92913322006-06-13 15:04:24 +00001484- Patch #1454481: thread stack size is now tunable at runtime for thread
1485 enabled builds on Windows and systems with Posix threads support.
1486
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001487- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1488 (up to the system limit of 32K characters).
1489
1490- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1491 As a result, these functions now raise WindowsError instead of OSError.
1492
Tim Peters7a822da2006-05-25 21:50:17 +00001493- ``time.clock()`` on Win64 should use the high-performance Windows
1494 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1495 Windows platforms).
1496
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001497- Calling Tk_Init twice is refused if the first call failed as that
1498 may deadlock.
1499
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001500- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1501 accept it without potentially using an uninitialized pointer.
1502
1503- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1504 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1505 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001506
Gregory P. Smith372b5832006-06-05 18:48:21 +00001507- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001508 [pybsddb project SF patch number 1466734]
1509
Gregory P. Smith372b5832006-06-05 18:48:21 +00001510- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1511 parameter is supplied. [SF pybsddb bug #1477863]
1512
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001513- bsddb: the __len__ method of a DB object has been fixed to return correct
1514 results. It could previously incorrectly return 0 in some cases.
1515 Fixes SF bug 1493322 (pybsddb bug 1184012).
1516
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001517- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1518 aborts the db transaction safely when a modifier callback fails.
1519 Fixes SF python patch/bug #1408584.
1520
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001521- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001522 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001523 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1524 database calls that would previously deadlock. [SF python bug #775414]
1525
Vinay Sajip28e57612006-07-01 10:45:20 +00001526- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001527
Walter Dörwald4994d952006-06-19 08:07:50 +00001528- Patch #1506645: add Python wrappers for the curses functions
1529 is_term_resized, resize_term and resizeterm.

1548 mime.types file for determining MIME types.
1549
Georg Brandl2605ca82006-06-14 06:08:31 +00001550- Bug #1339007: Shelf objects now don't raise an exception in their
1551 __del__ method when initialization failed.
1552
Martin v. Löwisd8251432006-06-14 05:21:04 +00001553- Patch #1455898: The MBCS codec now supports the incremental mode for
1554 double-byte encodings.
1555
Tim Peters43898b42006-06-14 04:09:25 +00001556- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1557 guarantee that adjacent triples in the return list always describe
1558 non-adjacent blocks. Previously, a pair of matching blocks could end
1559 up being described by multiple adjacent triples that formed a partition
1560 of the matching pair.
1561
Greg Ward0e0c9f42006-06-11 16:24:11 +00001562- Bug #1498146: fix optparse to handle Unicode strings in option help,
1563 description, and epilog.
1564
Greg Wardd1c797e2006-06-11 14:42:41 +00001565- Bug #1366250: minor optparse documentation error.

1568 clarify docs.
1569
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001570- The wsgiref package has been added to the standard library.
1571
Nick Coghlan676725d2006-06-08 13:54:49 +00001572- The functions update_wrapper() and wraps() have been added to the functools
1573 module. These make it easier to copy relevant metadata from the original
1574 function when writing wrapper functions.
1575
Tim Petersd6a9eef2006-06-05 01:48:21 +00001576- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1577 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001578
Martin v. Löwis3f767792006-06-04 19:36:28 +00001579- Patch #1359618: Speed up charmap encoder by using a trie structure
1580 for lookup.
1581
Tim Petersd609b1a2006-06-02 23:22:51 +00001582- The functions in the ``pprint`` module now sort dictionaries by key
1583 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1584 if and only if its display required more than one line, although that
1585 wasn't documented. The new behavior increases predictability; e.g.,
1586 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1587
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001588- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1590
Georg Brandl2b330372006-05-28 20:23:12 +00001591- Patch #1496206: improve urllib2 handling of passwords with respect to
1592 default HTTP and HTTPS ports.
1593
George Yoshidaf3c65de2006-05-28 16:39:09 +00001594- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1595
Bob Ippolito7298f272006-05-23 18:43:47 +00001596- Patch #1281707: speed up gzip.readline.
1597
Georg Brandlb89316f2006-05-17 15:51:16 +00001598- Patch #1180296: Two new functions were added to the locale module:
1599 format_string() to get the effect of "format % items" but locale-aware,
1600 and currency() to format a monetary number with currency sign.
1601
Georg Brandle3a25832006-05-17 14:56:04 +00001602- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1603 and several features added, such as speed and geometry control.
1604
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001605- Patch #1488881: add support for external file objects in bz2 compressed
1606 tarfiles.
1607
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001608- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1609 stdout arguments, making it possible to redirect input and output
1610 for remote debugging.
1611
1612- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1613 a couple of issues, notably handling of long file names using the
1614 GNU LONGNAME extension.
1615
1616- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1617 new flag when ``name`` is already the name of an option flag.
1618
1619- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1620 package.
1621
1622- Patch #1472854: make the rlcompleter.Completer class usable on non-
1623 UNIX platforms.

1664-----------------
1665
Thomas Heller1b046642006-04-18 18:51:06 +00001666- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1667 by converting these apis from macros into exported functions again:
1668
1669 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1670 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1671 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1672 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1673 PyRun_String Py_CompileString
1674
Martin v. Löwis45294a92006-04-18 06:24:08 +00001675- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1676
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001677- All uses of PyStructSequence_InitType have been changed to initialize
1678 the type objects only once, even if the interpreter is initialized
1679 multiple times.
1680
Neal Norwitz61546162006-04-14 05:20:28 +00001681- Bug #1454485, array.array('u') could crash the interpreter. This was
1682 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1683 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1684
1685- Py_UNICODE is unsigned. It was always documented as unsigned, but
1686 due to a bug had a signed value in previous versions.
1687
Tim Peters3a5e8b12006-04-11 01:44:07 +00001688- Patch #837242: ``id()`` of any Python object always gives a positive
1689 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1690 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001691 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001692 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001693
Tim Peters3a5e8b12006-04-11 01:44:07 +00001694 def __hash__(self):
1695 return id(self) # WRONG
1696
1697 because a hash result must be a (short) Python int but it was always
1698 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001699 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001700 was always usable as a hash value before this patch. That's no longer
1701 necessarily so.
1702
1703- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001704 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001705 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001706 #1454844)
1707
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001708- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1709 involving generators that have paused outside of any ``try`` or ``with``
1710 blocks. (In 2.5a1, a paused generator that was part of a reference
1711 cycle could not be garbage collected, regardless of whether it was
1712 paused in a ``try`` or ``with`` block.)

1726 the cachesize parameter.
1727
1728- Bug #1149413: bsddb.*open() no longer raises an exception when using
1729 a temporary db (file=None) with the 'n' flag to truncate on open.
1730
1731- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1732 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001733
Armin Rigoa9017c32006-04-19 11:50:27 +00001734- Patch #1062014: AF_UNIX sockets under Linux have a special

1738-------
1739
Peter Astrand7d1d4362006-07-14 14:04:45 +00001740- Bug #1223937: subprocess.CalledProcessError reports the exit status
1741 of the process using the returncode attribute, instead of
1742 abusing errno.
1743
Tim Peters711bf302006-04-25 03:31:36 +00001744- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1745 a doctest to be skipped (the code is not run, and the expected output
1746 or exception is ignored).
1747
Nick Coghlanda2268f2006-04-24 04:37:15 +00001748- Fixed contextlib.nested to cope with exceptions being raised and
1749 caught inside exit handlers.
1750
Greg Wardab05edc2006-04-23 03:47:58 +00001751- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1752 hex, octal, or binary; add ``append_const`` action; keep going if
1753 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1754 added ``epilog`` for better help generation).
1755
Tim Peters21fbd572006-04-21 21:18:10 +00001756- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1757 called from a thread spawned as a side effect of importing a module.
1758
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001759- The pydoc module now supports documenting packages contained in
1760 .zip or .egg files.
1761
1762- The pkgutil module now has several new utility functions, such
1763 as ``walk_packages()`` to support working with packages that are either
1764 in the filesystem or zip files.
1765
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001766- The mailbox module can now modify and delete messages from
1767 mailboxes, in addition to simply reading them. Thanks to Gregory
1768 K. Johnson for writing the code, and to the 2005 Google Summer of
1769 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001770
Tim Petersc7605f22006-04-17 21:12:33 +00001771- The ``__del__`` method of class ``local`` in module ``_threading_local``
1772 returned before accomplishing any of its intended cleanup.
1773
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001774- Patch #790710: Add breakpoint command lists in pdb.
1775

Skip Montanaro262fb922006-04-21 02:31:07 +00001794- The pstats.Stats class accepts an optional stream keyword argument to
1795 direct output to an alternate file-like object.
1796
Anthony Baxter51bcb682006-04-05 14:51:42 +00001797Build
1798-----
1799
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001800- The Makefile now has a reindent target, which runs reindent.py on
1801 the library.
1802
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001803- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001806
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001807- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1808 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001809 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001810 CXX from --with-cxx-main, see description in README.
1811
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001812- Patch #1429775: Link extension modules with the shared libpython.
1813
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001814- Fixed a libffi build problem on MIPS systems.
1815
Tim Peters8931ff12006-05-13 23:28:20 +00001816- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1817 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1818 and "%zu" for unsigned integers of type ``size_t``.
1819
Anthony Baxter51bcb682006-04-05 14:51:42 +00001820Tests
1821-----
1822
Nick Coghlanda2268f2006-04-24 04:37:15 +00001823- test_contextlib now checks contextlib.nested can cope with exceptions
1824 being raised and caught inside exit handlers.
1825
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001826- test_cmd_line now checks operation of the -m and -c command switches
1827
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001828- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1829 it separately and by hand. It also wasn't cleaning up its changes to
1830 the current Decimal context.
1831
Thomas Woutersabd08882006-04-26 15:53:30 +00001832- regrtest.py now has a -M option to run tests that test the new limits of
1833 containers, on 64-bit architectures. Running these tests is only sensible
1834 on 64-bit machines with more than two gigabytes of memory. The argument
1835 passed is the maximum amount of memory for the tests to use.
1836
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001837Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001843Documentation
1844-------------
1845
Tim Petersb06d28c2006-05-12 01:57:59 +00001846- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1847
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001848- PEP 343: Added Context Types section to the library reference
1849 and attempted to bring other PEP 343 related documentation into
1850 line with the implementation and/or python-dev discussions.
1851
Tim Peters8dc73d22006-04-24 02:03:16 +00001852- Bug #1337990: clarified that ``doctest`` does not support examples
1853 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001856What's New in Python 2.5 alpha 1?
1857=================================
1858
Anthony Baxterebed3f62006-04-03 15:03:44 +00001859*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001860
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001861Core and builtins
1862-----------------
1863
Nick Coghlan43832302006-04-23 17:04:07 +00001864- PEP 338: -m command line switch now delegates to runpy.run_module
1865 allowing it to support modules in packages and zipfiles
1866
Martin v. Löwisc661b882006-04-20 04:54:23 +00001867- On Windows, .DLL is not an accepted file name extension for
1868 extension modules anymore; extensions are only found if they
1869 end in .PYD.
1870
Martin v. Löwisea62d252006-04-03 10:56:49 +00001871- Bug #1421664: sys.stderr.encoding is now set to the same value as
1872 sys.stdout.encoding.
1873
Neal Norwitz92e212f2006-04-03 04:48:37 +00001874- __import__ accepts keyword arguments.
1875
Georg Brandlccadf842006-03-31 18:54:53 +00001876- Patch #1460496: round() now accepts keyword arguments.
1877
Anthony Baxter262c00a2006-03-30 10:53:17 +00001878- Fixed bug #1459029 - unicode reprs were double-escaped.
1879
Hye-Shik Changd478f342006-03-23 12:32:36 +00001880- Patch #1396919: The system scope threads are reenabled on FreeBSD
1881 5.4 and later versions.
1882
Neal Norwitze98ccf62006-03-23 05:39:47 +00001883- Bug #1115379: Compiling a Unicode string with an encoding declaration
1884 now gives a SyntaxError.
1885
Georg Brandlabd1ff82006-03-18 07:59:59 +00001886- Previously, Python code had no easy way to access the contents of a
1887 cell object. Now, a ``cell_contents`` attribute has been added
1888 (closes patch #1170323).
1889
Tim Peterscf79aac2006-03-16 01:14:46 +00001890- Patch #1123430: Python's small-object allocator now returns an arena to
1891 the system ``free()`` when all memory within an arena becomes unused
1892 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1893 freed. Some applications will see a drop in virtual memory size now,
1894 especially long-running applications that, from time to time, temporarily
1895 use a large number of small objects. Note that when Python returns an
1896 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001897 platform C library will in turn return that memory to the operating system.
1898 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001899 appears to be effective at least on Microsoft C and gcc-based systems.
1900 Thanks to Evan Jones for hard work and patience.
1901
Georg Brandl533ff6f2006-03-08 18:09:27 +00001902- Patch #1434038: property() now uses the getter's docstring if there is
1903 no "doc" argument given. This makes it possible to legitimately use
1904 property() as a decorator to produce a read-only property.
1905
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001906- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1907 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1908 of requiring an int or long in slicing and a few other contexts, enabling
1909 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1910
Neal Norwitz995acdf2006-03-07 05:01:00 +00001911- Fixed various bugs reported by Coverity's Prevent tool.
1912
Brett Cannonbf364092006-03-01 04:25:17 +00001913- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1914 new exception base class, BaseException, which has a new message attribute.
1915 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1916 Raising a string exception now raises a DeprecationWarning.
1917
Thomas Woutersfb609f42006-02-28 16:37:25 +00001918- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1919 explicitly relative, using 'from .module import name' to mean 'from the same
1920 package as this module is in. Imports without dots still default to the
1921 old relative-then-absolute, unless 'from __future__ import
1922 absolute_import' is used.
1923
Brett Cannona7446e32006-02-27 23:39:10 +00001924- Properly check if 'warnings' raises an exception (usually when a filter set
1925 to "error" is triggered) when raising a warning for raising string
1926 exceptions.
1927
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001928- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001929 The name was removed from Include/code.h.
1930
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001931- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001932
Guido van Rossum1968ad32006-02-25 22:38:04 +00001933- Patch 1433928:
1934 - The copy module now "copies" function objects (as atomic objects).
1935 - dict.__getitem__ now looks for a __missing__ hook before raising
1936 KeyError.
1937
Tim Peters84ef21c2006-02-28 20:39:06 +00001938- PEP 343: with statement implemented. Needs ``from __future__ import
1939 with_statement``. Use of 'with' as a variable will generate a warning.
1940 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001941 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001942 The following objects have __context__ methods:
1943 - The built-in file type.
1944 - The thread.LockType type.
1945 - The following types defined by the threading module:
1946 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1947 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001948
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001949- Fix the encodings package codec search function to only search
1950 inside its own package. Fixes problem reported in patch #1433198.
1951
1952 Note: Codec packages should implement and register their own
1953 codec search function. PEP 100 has the details.
1954
Tim Peters9ea89d22006-06-04 03:26:02 +00001955- PEP 353: Using ``Py_ssize_t`` as the index type.
1956
1957- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1958 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1959 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1960 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1961 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001962
Neal Norwitzfc76d632006-01-10 06:03:13 +00001963- Patch #1400181, fix unicode string formatting to not use the locale.
1964 This is how string objects work. u'%f' could use , instead of .
1965 for the decimal point. Now both strings and unicode always use periods.
1966
Neal Norwitz671b9e32006-01-09 07:07:12 +00001967- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1968 configure would break checking curses.h.
1969
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001970- Bug #959576: The pwd module is now builtin. This allows Python to be
1971 built on UNIX platforms without $HOME set.
1972
Neal Norwitzc10978f2005-12-19 06:07:16 +00001973- Bug #1072182, fix some potential problems if characters are signed.
1974
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001975- Bug #889500, fix line number on SyntaxWarning for global declarations.
1976
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001977- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1978
Neal Norwitze7214a12005-12-18 05:03:17 +00001979- Support for converting hex strings to floats no longer works.
1980 This was not portable. float('0x3') now raises a ValueError.
1981
Barry Warsaw2a38a862005-12-18 01:27:35 +00001982- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001983 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001984 is now displayed in interactive prompt banner.
1985
Georg Brandlfa166682005-12-17 21:45:17 +00001986- Implementation of PEP 341 - Unification of try/except and try/finally.
1987 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001988 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001989
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001990- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1991 now encodes backslash correctly.
1992
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001993- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1994
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001995- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001996 and long longs.
1997
Neal Norwitz67715f02005-11-09 06:59:35 +00001998- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001999 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002000 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002001
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002002- Replaced most Unicode charmap codecs with new ones using the
2003 new Unicode translate string feature in the builtin charmap
2004 codec; the codecs were created from the mapping tables available
2005 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2006 encodings now include a mapping for the Apple logo)
2007
Tim Peterse3547fd2005-12-16 23:13:57 +00002008- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002009
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002010- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002011
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002012- A new AST parser implementation was completed. The abstract
2013 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002014 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002015
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002016- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002017 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2018
Neal Norwitz708e51a2005-10-03 04:48:15 +00002019- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2020
Neal Norwitz11bd1192005-10-03 00:54:56 +00002021- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2022 Provide a warning when a directory is passed on the command line.
2023
Neal Norwitz40d37812005-10-02 01:48:49 +00002024- Fix segfault with invalid coding.
2025
2026- SF bug #772896: unknown encoding results in MemoryError.
2027
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002028- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002029 supported a __len__() method which evaluated to False when the iterator
2030 was empty.
2031
Guido van Rossum630db602005-09-20 18:49:54 +00002032- On 64-bit platforms, when __len__() returns a value that cannot be
2033 represented as a C int, raise OverflowError.
2034
Skip Montanarof8948ca2005-09-19 03:54:46 +00002035- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002036 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002037
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002038- SF bug #893549: parsing keyword arguments was broken with a few format
2039 codes.
2040
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002041- Changes donated by Elemental Security to make it work on AIX 5.3
2042 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2043 bug #105470: test_pwd fails on 64bit system (Opteron).
2044
Guido van Rossum539c6622005-09-14 17:49:54 +00002045- Changes donated by Elemental Security to make it work on HP-UX 11 on
2046 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2047
Georg Brandl4550b8d2005-08-26 06:43:52 +00002048- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002049 (fixes bug #1119418).
2050
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002051- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2052
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002053- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2054 exceptions that cause a function to exit.
2055
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002056- The implementation of set() and frozenset() was revised to use its
2057 own internal data structure. Memory consumption is reduced by 1/3
2058 and there are modest speed-ups as well. The API is unchanged.
2059
Tim Petersde7990b2005-07-17 23:45:23 +00002060- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2061
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002062- SF bug #1229429: PyObject_CallMethod failed to decrement some
2063 reference counts in some error exit cases.
2064
Tim Petersecc6e6a2005-07-10 22:30:55 +00002065- SF bug #1185883: Python's small-object memory allocator took over
2066 a block managed by the platform C library whenever a realloc specified
2067 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002068 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002069 portable way to copy data from the C-managed block into Python's
2070 small-object space without risking a memory fault. Python's small-object
2071 realloc now leaves such blocks under the control of the platform C
2072 realloc.
2073
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002074- SF bug #1232517: An overflow error was not detected properly when
2075 attempting to convert a large float to an int in os.utime().
2076
Raymond Hettinger3296e692005-06-29 23:29:56 +00002077- SF bug #1224347: hex longs now print with lowercase letters just
2078 like their int counterparts.
2079
Michael W. Hudson188d4362005-06-20 16:52:57 +00002080- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2081 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2082 interpreter states; back out that fix and do a better job (see
2083 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2084 for a longer write-up of the problem).
2085
Michael W. Hudsondf888462005-06-03 14:41:55 +00002086- SF patch #1180995: marshal now uses a binary format by default when
2087 serializing floats.
2088
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002089- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2090 the routines that promise to produce IEEE 754 binary representations
2091 of floats now simply copy bytes around.
2092
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002093- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2094 278.
2095
Brett Cannonc3647ac2005-04-26 03:45:26 +00002096- patch #1109424: int, long, float, complex, and unicode now check for the
2097 proper magic slot for type conversions when subclassed. Previously the
2098 magic slot was ignored during conversion. Semantics now match the way
2099 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002100 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002101 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002102 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002103
Barry Warsawc8d907c2005-04-19 23:43:40 +00002104- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2105 NULL, now raise an AttributeError when attempting to set or delete the
2106 attribute. Previously a TypeError was raised, but this was inconsistent
2107 with the equivalent pure-Python implementation.
2108
Michael W. Hudson774479c2005-04-18 08:46:17 +00002109- It is now safe to call PyGILState_Release() before
2110 PyEval_InitThreads() (note that if there is reason to believe there
2111 are multiple threads around you still must call PyEval_InitThreads()
2112 before using the Python API; this fix is for extension modules that
2113 have no way of knowing if Python is multi-threaded yet).
2114
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002115- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2116 disabled caused a crash.
2117
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002118- Bug #1165306: instancemethod_new allowed the creation of a method
2119 with im_class == im_self == NULL, which caused a crash when called.
2120
Tim Petersecc6e6a2005-07-10 22:30:55 +00002121- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002122 fixes the crash seen in bug #1165761
2123
Raymond Hettinger96229b12005-03-11 06:49:40 +00002124- Added two new builtins, any() and all().
2125
Brett Cannon409d8f22005-03-05 06:47:57 +00002126- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002127 (e.g., ``class C(): pass`` is no longer a syntax error).
2128 Patch #1176012 added support to the 'parser' module and 'compiler' package
2129 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002130
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002131- Patch #1115086: Support PY_LONGLONG in structmember.
2132
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002133- Bug #1155938: new style classes did not check that __init__() was
2134 returning None.
2135
Tim Petersecc6e6a2005-07-10 22:30:55 +00002136- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002137 ('\') with a specific error message.
2138
Martin v. Löwisff232d72005-03-03 09:24:38 +00002139- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2140
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002141- Bug #1124295: the __name__ attribute of file objects was
2142 inadvertently made inaccessible in restricted mode.
2143
Tim Petersecc6e6a2005-07-10 22:30:55 +00002144- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002145 an ferror() call.
2146
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002147- min() and max() now support key= arguments with the same meaning as in
2148 list.sort().
2149
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002150- The peephole optimizer now performs simple constant folding in expressions:
2151 (2+3) --> (5).
2152
Raymond Hettingera422c342005-01-11 03:03:27 +00002153- set and frozenset objects can now be marshalled. SF #1098985.
2154
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002155- Bug #1077106: Poor argument checking could cause memory corruption
2156 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002157
Jeremy Hyltonab630502005-02-04 18:44:06 +00002158- The parser did not complain about future statements in illegal
2159 positions. It once again reports a syntax error if a future
2160 statement occurs after anything other than a doc string.
2161
Neil Schemenauercf52c072005-08-12 17:34:58 +00002162- Change the %s format specifier for str objects so that it returns a
2163 unicode instance if the argument is not an instance of basestring and
2164 calling __str__ on the argument returns a unicode instance.
2165
Tim Petersf4e69282006-02-27 17:15:31 +00002166- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2167 current thread state when the auto-GIL-state machinery knows about
2168 it (since the thread state is being deleted, continuing to remember it
2169 can't help, but can hurt if another thread happens to get created with
2170 the same thread id).
2171
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002172Extension Modules
2173-----------------
2174

Neal Norwitz10be10c2006-03-16 06:50:13 +00002188 util, whatsound, whrandom, zmod
2189
2190- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2191
2192- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002193 is deprecated. The undocumented re.engine variable no longer exists.
2194

2196 SS2 (single-shift 2) escape sequences correctly.
2197
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002198- The unicodedata module was updated to the 4.1 version of the Unicode
2199 database. The 3.2 version is still available as unicodedata.db_3_2_0
2200 for applications that require this specific version (such as IDNA).
2201
Neal Norwitzb62c4332006-03-04 18:35:47 +00002202- The timing module is no longer built by default. It was deprecated
2203 in PEP 4 in Python 2.0 or earlier.
2204
Guido van Rossum1968ad32006-02-25 22:38:04 +00002205- Patch 1433928: Added a new type, defaultdict, to the collections module.
2206 This uses the new __missing__ hook behavior added to dict (see above).
2207
Georg Brandldbd83392006-02-20 09:42:33 +00002208- Bug #854823: socketmodule now builds on Sun platforms even when

2210
Georg Brandlf4f44152006-02-18 22:29:33 +00002211- Patch #1393157: os.startfile() now has an optional argument to specify
2212 a "command verb" to invoke on the file.
2213

2222 than the system default domain.
2223
Martin v. Löwis14694662006-02-03 12:54:16 +00002224- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2225 are reported, the limit on path name lengths is removed, and stat reports
2226 WindowsError now (instead of OSError).
2227
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002228- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2303 the request code argument, which results in more C-like behaviour
2304 for large or negative values.
2305
Tim Petersecc6e6a2005-07-10 22:30:55 +00002306- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Tim Peters112aad32006-07-19 00:03:19 +00002361
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002362- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2363 been renamed to have only a single underscore prefix. This was done to
2364 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002365
Nick Coghlan43832302006-04-23 17:04:07 +00002366- PEP 338: new module runpy defines a run_module function to support
2367 executing modules which provide access to source code or a code object
2368 via the PEP 302 import mechanisms.
2369
Anthony Baxter93f5b932006-04-03 08:05:07 +00002370- The email module's parsedate_tz function now sets the daylight savings

2378 in attribute values.
2379
Anthony Baxterc51ee692006-04-01 00:57:31 +00002380- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002381 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002382 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002383 module will not be built.
2384
Tim Petersc17976e2006-04-01 00:26:53 +00002385- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2386 aren't officially supported here, and trying to use them will probably
2387 raise an exception some day. But dicts have been allowed, and "mostly
2388 worked", so support for them won't go away without warning.
2389
Georg Brandl338ef7d2006-03-31 18:42:16 +00002390- Bug #1445068: getpass.getpass() can now be given an explicit stream
2391 argument to specify where to write the prompt.
2392
Georg Brandl22ec80b2006-03-31 18:25:44 +00002393- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2402 to make it easier to monitor when daemon threads have completed
2403 processing all enqueued tasks. Patch #1455676.
2404
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002405- popen2.Popen objects now preserve the command in a .cmd attribute.

2408
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002409- email 4.0 package now integrated. This is largely the same as the email 3.0
2410 package that was included in Python 2.3, except that PEP 8 module names are
2411 now used (e.g. mail.message instead of email.Message). The MIME classes
2412 have been moved to a subpackage (e.g. email.mime.text instead of
2413 email.MIMEText). The old names are still supported for now. Several
2414 deprecated Message methods have been removed and lots of bugs have been
2415 fixed. More details can be found in the email package documentation.
2416
Walter Dörwald40108c92006-03-27 08:15:44 +00002417- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2418 (a subclass of tuple) that provides incremental decoders and encoders
2419 (a way to use stateful codecs without the stream API). Python functions
2420 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2421 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2422 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002423
Walter Dörwald067db482006-03-15 22:17:27 +00002424- Patch #1359365: Calling next() on a closed StringIO.String object raises
2425 a ValueError instead of a StopIteration now (like file and cString.String do).
2426 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2427 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002428
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002429- A regrtest option -w was added to re-run failed tests in verbose mode.

2441 and helpful context managers nested() and closing().
2442

Tim Peterse3547fd2005-12-16 23:13:57 +00002501 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2502 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2503 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2504 Ronald L. Rivest offered this advice for Python:
2505
2506 "The consensus of researchers in this area (at least as
2507 expressed at the NIST Hash Function Workshop 10/31/05),
2508 is that SHA-256 is a good choice for the time being, but
2509 that research should continue, and other alternatives may
2510 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002511
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002512- Added a subset of Fredrik Lundh's ElementTree package. Available

2580 docstrings to either "article number" or "message id".
2581
Georg Brandla4a8b822005-07-15 09:13:21 +00002582- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2583 parameter, but uses the usual "kwargs=None".
2584
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002585- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002586 Patch #1209527 (Contributed by Connelly).
2587
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002588- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2589 to W3C name (404 -> 'Not Found'). RFE #1216944.
2590
Georg Brandl9e43acf2005-07-04 17:16:07 +00002591- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2592 as this can cause problems with apps closing all file descriptors.
2593
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002594- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002595 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002596
Georg Brandl2f210b62005-06-26 22:09:06 +00002597- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2598
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002599- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2600 error messages.
2601
Georg Brandl379f99d2005-06-26 21:09:38 +00002602- Bug #1108948: Cookie.py produced invalid JavaScript code.
2603
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002604- The tokenize module now detects and reports indentation errors.
2605 Bug #1224621.
2606
Raymond Hettinger68c04532005-06-10 11:05:19 +00002607- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002608 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002609 the generate_tokens() function now accepts a callable argument that
2610 terminates by raising StopIteration.
2611
Georg Brandl9166e1a2005-06-04 09:20:03 +00002612- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2613
Georg Brandl268e61c2005-06-03 14:28:50 +00002614- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2615 component of the path.
2616
Skip Montanaro174dd222005-05-14 20:54:16 +00002617- Patch #1120353: The xmlrpclib module provides better, more transparent,
2618 support for datetime.{datetime,date,time} objects. With use_datetime set
2619 to True, applications shouldn't have to fiddle with the DateTime wrapper
2620 class at all.
2621
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002622- distutils.commands.upload was added to support uploading distribution
2623 files to PyPI.
2624
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002625- distutils.commands.register now encodes the data as UTF-8 before posting
2626 them to PyPI.
2627
Raymond Hettinger267b8682005-03-27 10:47:39 +00002628- decimal operator and comparison methods now return NotImplemented
2629 instead of raising a TypeError when interacting with other types. This
2630 allows other classes to implement __radd__ style methods and have them
2631 work as expected.
2632
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002633- Bug #1163325: Decimal infinities failed to hash. Attempting to
2634 hash a NaN raised an InvalidOperation instead of a TypeError.
2635
Tim Petersecc6e6a2005-07-10 22:30:55 +00002636- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002637 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2638
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002639- Patch #1043890: Add extractall method to tarfile.

2642 to build.
2643
Martin v. Löwis637431b2005-03-03 23:12:42 +00002644- Patch #1103407: Properly deal with tarfile iterators when untarring

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002648 profile.py if available.
2649
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002650- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2651

2668
Raymond Hettingerbab41432005-02-05 01:31:19 +00002669- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2670
Guido van Rossumd0641422005-02-03 15:01:24 +00002671- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2672 disables recursive traversal through instance attributes, which can
2673 be exploited in various ways.
2674
Tim Peterse3547fd2005-12-16 23:13:57 +00002675- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002676 flags on the HTTP listening socket.
2677
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002678- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2679 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2680
Fred Drakefbdeaad2006-07-29 16:56:15 +00002681- Patches #893642, #1039083: add allow_none, encoding arguments to
2682 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002683
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002684- Bug #1110478: Revert os.environ.update to do putenv again.
2685
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002686- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2687
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002688- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2689
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002690- Enhancements to the csv module:
2691
2692 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002693 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002694 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002695 + Dialect parameter parsing has been re-implemented to improve error
2696 reporting.
2697 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2698 dictates.
2699 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002700 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002701 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002702 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2703 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002704 + reader now allows \r characters to be quoted (previously it only allowed
2705 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002706 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002707 + Dialect classes passed to the module are no longer instantiated by
2708 the module before being parsed (the former validation scheme required
2709 this, but the mechanism was unreliable).
2710 + The dialect registry now contains instances of the internal
2711 C-coded dialect type, rather than references to python objects.
2712 + the internal c-coded dialect type is now immutable.
2713 + register_dialect now accepts the same keyword dialect specifications
2714 as the reader and writer, allowing the user to register dialects
2715 without first creating a dialect class.
2716 + a configurable limit to the size of parsed fields has been added -
2717 previously, an unmatched quote character could result in the entire
2718 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002719 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002720 the parser field size limit (returning the former limit). The initial
2721 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002722 + A line_num attribute has been added to the reader object, which tracks
2723 the number of lines read from the source iterator. This is not
2724 the same as the number of records returned, as records can span
2725 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002726 + reader and writer objects were not being registered with the cyclic-GC.
2727 This has been fixed.
2728
Brett Cannone6539c42005-01-08 02:43:53 +00002729- _DummyThread objects in the threading module now delete self.__block that is
2730 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2731 lock primitives tend to be limited in number and thus should not be wasted on
2732 a _DummyThread object. Fixes bug #1089632.
2733
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002734- The imghdr module now detects Exif files.
2735
Raymond Hettinger6065d322004-12-20 23:51:53 +00002736- StringIO.truncate() now correctly adjusts the size attribute.
2737 (Bug #951915).
2738
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002739- locale.py now uses an updated locale alias table (built using
2740 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2741 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002742 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002743
Raymond Hettinger3557f422004-12-07 12:02:02 +00002744- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2745
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002746- the pickle module no longer accepts the deprecated None option in the
2747 args tuple returned by __reduce__().
2748
Brett Cannon84667c02004-12-07 03:25:18 +00002749- optparse now optionally imports gettext. This allows its use in setup.py.
2750
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002751- the pickle module no longer uses the deprecated bin parameter.
2752
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002753- the shelve module no longer uses the deprecated binary parameter.
2754
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002755- the pstats module no longer uses the deprecated ignore() method.
2756
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002757- the filecmp module no longer uses the deprecated use_statcache argument.
2758
Raymond Hettinger664347b2004-12-04 21:21:53 +00002759- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2760 extended or overridden by subclasses. Formerly, the subclassed method would
2761 be ignored by the rest of the module. (Bug #1078905).
2762
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002763- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002764 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002765
Walter Dörwald36733692004-12-22 12:50:50 +00002766- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2767 once when a size argument is given. This prevents a buffer overflow in the
2768 tokenizer with very long source lines.
2769
Barry Warsaw538561e2006-01-01 21:48:54 +00002770- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2771 immediately after creating the object, without any intervening
2772 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002773
Skip Montanaro05885812005-01-16 20:48:27 +00002774- The reconvert.quote function can now emit triple-quoted strings. The
2775 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002776
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002777- ``UserString.MutableString`` now supports negative indices in
2778 ``__setitem__`` and ``__delitem__``
2779
Greg Ward40407942005-03-05 02:53:17 +00002780- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2781 correctly.
2782
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002783- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2784 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2785 character even if the user has passed a size parameter to get a proper
2786 line ending. Remove the special handling of a "\r\n" that has been split
2787 between two lines.
2788
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002789- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2790 about illegal code points. The codec now supports PEP 293 style error
2791 handlers.
2792
Walter Dörwald78a78b02005-09-01 12:04:29 +00002793- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002794 from the input stream, so that the output is a byte string in the correct
2795 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002796
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002797- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2798 considering it exactly like a '*'.
2799
Walter Dörwald007f8df2005-10-09 19:42:27 +00002800- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2801 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002802
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002803- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2804
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002805- Patch #1413711: Certain patterns of differences were making difflib
2806 touch the recursion limit.
2807
Walter Dörwald58917a62006-03-31 15:26:22 +00002808- Bug #947906: An object oriented interface has been added to the calendar
2809 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002810 called as a script (e.g. via ``python -mcalendar``). Localized month and
2811 weekday names can be ouput (even if an exotic encoding is used) using
2812 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002813

2837 vulnerability in zlib 1.2.1 and 1.2.2.
2838
Brett Cannon08cd5982005-04-24 22:26:38 +00002839- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2840 flags that change binary compatibility. Changes were also made to
2841 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002842 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00002844- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2845 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2846 no longer exists). This configure patch makes things right.
2847
Martin v. Löwise2713be2005-03-08 15:03:08 +00002848- Bug #1158607: Build with --disable-unicode again.
2849
Brett Cannon46d96232005-02-16 00:07:19 +00002850- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2851 defined. Discovered as a result of not being able to build on OS X.
2852
Brett Cannon516592f2004-12-07 00:42:59 +00002853- setup.py now uses the directories specified in LDFLAGS using the -L option
2854 and in CPPFLAGS using the -I option for adding library and include
2855 directories, respectively, for compiling extension modules against. This has
2856 led to the core being compiled using the values in CPPFLAGS. It also removes
2857 the need for the special-casing of both DarwinPorts and Fink for darwin since
2858 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2859 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2860 Fink, ``-I/opt/local/include`` for DarwinPorts).
2861
Brett Cannon43802422005-02-10 20:48:03 +00002862- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2863 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2864 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2865 Closes bug #1096244. Thanks Gregory Bond.

2868-----
2869
Tim Petersc9d78aa2006-03-26 23:27:58 +00002870- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2871 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2872 is obtained via the ``PyObject_`` family, it must be released via the
2873 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2874 always been officially true, but when Python's small-object allocator was
2875 introduced, an attempt was made to cater to a few extension modules
2876 discovered at the time that obtained memory via ``PyObject_New`` but
2877 released it via ``PyMem_DEL``. It's years later, and if such code still
2878 exists it will fail now (probably with segfaults, but calling wrong
2879 low-level memory management functions can yield many symptoms).
2880
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002881- Added a C API for set and frozenset objects.
2882
Raymond Hettinger66517482004-12-03 11:45:13 +00002883- Removed PyRange_New().
2884
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002885- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2886 mapping argument now. This string is used as a mapping table. Byte values
2887 greater than the length of the string and 0xFFFE are treated as undefined
2888 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002896- Patch #1276356: New resource "urlfetch" is implemented. This enables
2897 even impatient people to run tests that require remote files.
