Neal Norwitz0ac60192007-05-27 04:08:54 +000024- Add new attribute names for function objects. All the func_* become
25 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
26
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000027- Add -3 option to the interpreter to warn about features that are
28 deprecated and will be changed/removed in Python 3.0.
29
Georg Brandl2134e752007-05-21 20:34:16 +000030- Patch #1686487: you can now pass any mapping after '**' in function
31 calls.
32
Collin Winter62903052007-05-18 23:11:24 +000033- except clauses may now be spelled either "except E, target:" or
34 "except E as target:". This is to provide forwards compatibility with
35 Python 3.0.
36
Brett Cannon229cee22007-05-05 01:34:02 +000037- Deprecate BaseException.message as per PEP 352.
38
Armin Rigo9790a272007-05-02 19:23:31 +000039- Bug #1303614: don't expose object's __dict__ when the dict is
40 inherited from a builtin base.
41
Vinay Sajip8549ce32007-05-06 17:53:37 +000042- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000043 setting a plain string, ie don't expand to single letter identifiers.
44
Raymond Hettinger13936692007-04-11 18:40:58 +000045- Request #1191699: Slices can now be pickled.
46
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000047- Request #1193128: str.translate() now allows a None argument for
48 translations that only remove characters without re-mapping the
49 remaining characters.
50
Georg Brandl5cb76c12007-03-21 09:00:39 +000051- Patch #1682205: a TypeError while unpacking an iterable is no longer
52 masked by a generic one with the message "unpack non-sequence".
53
Neal Norwitzaa754b72007-03-21 06:39:48 +000054- Remove unused file Python/fmod.c.
55
Guido van Rossum143b5642007-03-23 04:58:42 +000056- Bug #1683368: The object.__init__() and object.__new__() methods are
57 now stricter in rejecting excess arguments. The only time when
58 either allows excess arguments is when it is not overridden and the
59 other one is. For backwards compatibility, when both are
60 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000061 warning later). Also, type.__init__() insists on the same signature
62 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000063
Georg Brandl2b869942007-03-17 16:08:45 +000064- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
65 to complex using its __complex__() method before falling back to the
66 __float__() method. Therefore, the functions in the cmath module now
67 can operate on objects that define a __complex__() method.
68
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000069- Patch #1623563: allow __class__ assignment for classes with __slots__.
70 The old and the new class are still required to have the same slot names.
71
Collin Winter77c67bd2007-03-16 04:11:30 +000072- Patch #1642547: Fix an error/crash when encountering syntax errors in
73 complex if statements.
74
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000075- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
76 is called with an object that is faking its type.
77
Žiga Seilnacht71436f02007-03-14 12:24:09 +000078- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
79 name.
80
Georg Brandl5240d742007-03-13 20:46:32 +000081- Patch #1444529: the builtin compile() now accepts keyword arguments.
82
Georg Brandl7b9c5552007-03-12 14:30:05 +000083- Bug #1678647: write a newline after printing an exception in any
84 case, even when converting the value to a string failed.
85
Georg Brandl871f1bc2007-03-12 13:17:36 +000086- The dir() function has been extended to call the __dir__() method on
87 its argument, if it exists. If not, it will work like before. This allows
88 customizing the output of dir() in the presence of a __getattr__().
89
Collin Winter276887b2007-03-12 16:11:39 +000090- Patch #922167: Python no longer segfaults when faced with infinitely
91 self-recursive reload() calls (as reported by bug #742342).
92
Žiga Seilnacht89032082007-03-11 15:54:54 +000093- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
94
Collin Wintere38051d2007-03-09 20:33:07 +000095- Patch #1491866: change the complex() constructor to allow parthensized
96 forms. This means complex(repr(x)) now works instead of raising a
97 ValueError.
98
Georg Brandlaa2321b2007-03-07 00:40:28 +000099- Patch #703779: unset __file__ in __main__ after running a file. This
100 makes the filenames the warning module prints much more sensible when
101 a PYTHONSTARTUP file is used.
102
Georg Brandl49aafc92007-03-07 00:34:46 +0000103- Variant of patch #697613: don't exit the interpreter on a SystemExit
104 exception if the -i command line option or PYTHONINSPECT environment
105 variable is given, but break into the interactive interpreter just like
106 on other exceptions or normal program exit.
107
Georg Brandl00cd8182007-03-06 18:41:12 +0000108- Patch #1638879: don't accept strings with embedded NUL bytes in long().
109
Georg Brandl098cd692007-03-06 12:17:50 +0000110- Bug #1674503: close the file opened by execfile() in an error condition.
111
Georg Brandl0fca97a2007-03-05 22:28:08 +0000112- Patch #1674228: when assigning a slice (old-style), check for the
113 sq_ass_slice instead of the sq_slice slot.
114
Neal Norwitz88516a62007-02-26 22:41:45 +0000115- When printing an unraisable error, don't print exceptions. before the name.
116 This duplicates the behavior whening normally printing exceptions.
117
Martin v. Löwisfd963262007-02-09 12:19:32 +0000118- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
119
Brett Cannon129bd522007-01-30 21:34:36 +0000120- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
121 catch a string exception raises DeprecationWarning.
122
Brett Cannonf5bee302007-01-23 23:21:22 +0000123- Bug #1377858: Fix the segfaulting of the interpreter when an object created
124 a weakref on itself during a __del__ call for new-style classes (classic
125 classes still have the bug).
126
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000127- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
128 frame's thread state.
129
Thomas Wouters6ed19652007-01-23 13:50:49 +0000130- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py

135 raised a warning.
136
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000137- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
138 to avoid relying on atexit.
139

157 again, no longer the posix error code.
158
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000159- Patch #1549049: Support long values in structmember, issue warnings

161
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000162- Update the peephole optimizer to remove more dead code (jumps after returns)
163 and inline unconditional jumps to returns.
164
Georg Brandl2c1375c2006-10-12 11:27:59 +0000165- Bug #1545497: when given an explicit base, int() did ignore NULs
166 embedded in the string to convert.
167
Georg Brandl846f73a2006-10-08 07:11:54 +0000168- Bug #1569998: break inside a try statement (outside a loop) is now
169 recognized and rejected.
170
Armin Rigo7ccbca92006-10-04 12:17:45 +0000171- list.pop(x) accepts any object x following the __index__ protocol.
172
173- Fix some leftovers from the conversion from int to Py_ssize_t
174 (relevant to strings and sequences of more than 2**31 items).
175
176- A number of places, including integer negation and absolute value,
177 were fixed to not rely on undefined behaviour of the C compiler
178 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000179

199
Georg Brandlec6c2df2006-09-11 09:38:35 +0000200- Make _PyGILState_NoteThreadState() static, it was not used anywhere

309
Vinay Sajip8549ce32007-05-06 17:53:37 +0000310- Patch #1676823: Added create_connection() to socket.py, which may be

323 directories.
324
Georg Brandl8f06d022007-03-16 07:55:09 +0000325- Bug #1681228: the webbrowser module now correctly uses the default
326 GNOME or KDE browser, depending on whether there is a session of one
327 of those present. Also, it tries the Windows default browser before
328 trying Mozilla variants.
329

345 correctly now.
346
Georg Brandlbad6f192007-03-13 21:32:56 +0000347- The nonobvious commands.getstatus() function is now deprecated.

417 and TestSuite subclasses (not instances) are no longer accepted in
418 TestSuite.addTest(). This should cause no incompatibility since it

954Core and builtins
955-----------------
956
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000957- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000958 compared equal or unequal to a string and a UnicodeDecodeError
959 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000960
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000961 Instead, the equal (==) and unequal (!=) comparison operators will
962 now issue a UnicodeWarning and interpret the two objects as
963 unequal. The UnicodeWarning can be filtered as desired using
964 the warning framework, e.g. silenced completely, turned into an
965 exception, logged, etc.
966
967 Note that compare operators other than equal and unequal will still
968 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000969
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000970- Fix segfault when doing string formatting on subclasses of long.
971
972- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
973 with new-style classes.
974
975- Fix bug related to __len__ functions returning negative values with
976 classic classes.
977
978- Patch #1538606, Fix __index__() clipping. There were some problems
979 discovered with the API and how integers that didn't fit into Py_ssize_t
980 were handled. This patch attempts to provide enough alternatives
981 to effectively use __index__.
982
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000983- Bug #1536021: __hash__ may now return long int; the final hash
984 value is obtained by invoking hash on the long int.
985
Thomas Hellerab1049c2006-08-08 17:37:00 +0000986- Bug #1536786: buffer comparison could emit a RuntimeWarning.
987
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000988- Bug #1535165: fixed a segfault in input() and raw_input() when
989 sys.stdin is closed.
990
Thomas Heller74d36f02006-08-04 18:17:40 +0000991- On Windows, the PyErr_Warn function is now exported from
992 the Python dll again.
993
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000994- Bug #1191458: tracing over for loops now produces a line event
995 on each iteration. Fixing this problem required changing the .pyc
996 magic number. This means that .pyc files generated before 2.5c1
997 will be regenerated.
998
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000999- Bug #1333982: string/number constants were inappropriately stored
1000 in the byte code and co_consts even if they were not used, ie
1001 immediately popped off the stack.
1002
Georg Brandle9462c72006-08-04 18:03:37 +00001003- Fixed a reference-counting problem in property().

1006Library
1007-------
1008
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001009- Fix a bug in the ``compiler`` package that caused invalid code to be
1010 generated for generator expressions.
1011
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001012- The distutils version has been changed to 2.5.0. The change to
1013 keep it programmatically in sync with the Python version running
1014 the code (introduced in 2.5b3) has been reverted. It will continue
1015 to be maintained manually as static string literal.
1016
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001017- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001018 and this cannot be converted to the required C type, an exception is
1019 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001020 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001021
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001022- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001023 an exception.
1024
Tim Petersc10c9d02006-09-05 02:18:09 +00001025- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001026 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001027 workarounds for clocks with low resolution, to stop the code yielding
1028 duplicate UUIDs.
1029
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001030- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1031 before raising SystemExit, allowing IDLE to honor quit() and exit().
1032
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001033- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1034
Georg Brandl7a1af772006-08-14 21:55:28 +00001035- Patch #1536071: trace.py should now find the full module name of a
1036 file correctly even on Windows.
1037
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001038- logging's atexit hook now runs even if the rest of the module has
1039 already been cleaned up.
1040
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001041- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001042
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001043- Bug #1531405, format_exception no longer raises an exception if
1044 str(exception) raised an exception.
1045
Neil Schemenauer06ded092006-08-04 16:20:30 +00001046- Fix a bug in the ``compiler`` package that caused invalid code to be
1047 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001055- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1056 raises the correct exceptions.
1057
Thomas Heller1ce433e2006-08-14 16:20:04 +00001058- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1059 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1060
Thomas Heller86720042006-08-14 11:17:48 +00001061- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1062 uses the _as_parameter_ attribute when objects are passed to foreign
1063 function calls. The ctypes version number was changed to 1.0.1.
1064
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001065- Bug #1530559, struct.pack raises TypeError where it used to convert.
1066 Passing float arguments to struct.pack when integers are expected
1067 now triggers a DeprecationWarning.
1068

1118-----------------
1119
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001120- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001121 returned a long (see PEP 353).
1122
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001123- Bug #1515471: string.replace() accepts character buffers again.
1124
Neal Norwitz07aadb12006-07-30 06:55:48 +00001125- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1126 This provides the proper warning for struct.pack().
1127 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1128
Neal Norwitz0d62a062006-07-30 06:53:31 +00001129- Patch #1531113: Fix augmented assignment with yield expressions.
1130 Also fix a SystemError when trying to assign to yield expressions.
1131
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001132- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1133 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1134 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1135 excessive filesystem operations during imports.
1136
Tim Petersbc24eee2006-07-27 01:14:53 +00001137- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1138 operations on signed longs that are formally undefined by C.
1139 Unfortunately, at least one compiler now cares about that, so complicated
1140 the code to make that compiler happy again.
1141
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001142- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1143

1145 path on Windows.
1146
Neal Norwitze1fdb322006-07-21 05:32:28 +00001147- Fix some potential crashes found with failmalloc.
1148
Neal Norwitze7563102006-07-17 01:00:16 +00001149- Fix warnings reported by Klocwork's static analysis tool.

1152 had more than 255 blank lines.
1153
Georg Brandl9dceedb2006-07-12 15:31:17 +00001154- Patch #1521179: Python now accepts the standard options ``--help`` and
1155 ``--version`` as well as ``/?`` on Windows.
1156
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001157- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001158 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001159 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001160
Tim Peters112aad32006-07-19 00:03:19 +00001161- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001162 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001163 new ``sys._current_frames()`` returns a dictionary with one entry,
1164 mapping the faux "thread id" 0 to the current frame.
1165
Ronald Oussoren3075e162006-07-25 20:28:55 +00001166- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +00001172- Correction of patch #1455898: In the mbcs decoder, set final=False
1173 for stream decoder, but final=True for the decode function.
1174
Georg Brandl07fec3a2006-08-01 18:49:24 +00001175- os.urandom no longer masks unrelated exceptions like SystemExit or
1176 KeyboardInterrupt.
1177
Tim Peters4643c2f2006-08-10 22:45:34 +00001178- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001179 shutil.copytree on Windows
1180
Georg Brandle34ac7c2006-07-30 11:07:23 +00001181- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1182 refers to file descriptors, not file objects.
1183
Tim Petersc10c9d02006-09-05 02:18:09 +00001184- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001185 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001186 #1513611, and probably others.
1187
Georg Brandledd9b0d2006-07-29 09:33:26 +00001188- Bug #1441397: The compiler module now recognizes module and function
1189 docstrings correctly as it did in Python 2.4.
1190
Tim Peters6f681472006-07-27 23:44:37 +00001191- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1192 lost that tests are sorted by name before being run. This rarely
1193 matters for well-written tests, but can create baffling symptoms if
1194 side effects from one test to the next affect outcomes. ``DocTestFinder``
1195 has been changed to sort the list of tests it returns.
1196
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001197- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001198 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001199
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001200- Bug #978833: Really close underlying socket in _socketobject.close.
1201
Georg Brandl8c036cc2006-08-20 13:15:39 +00001202- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1203 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001204
Georg Brandlcf0c1722006-07-26 07:23:32 +00001205- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1206 to recursive calls and call it with the failing package name.
1207
Martin v. Löwis0b483032006-07-25 09:53:12 +00001208- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1209
Georg Brandlc13c34c2006-07-24 14:09:56 +00001210- Patch #1515343: Fix printing of deprecated string exceptions with a
1211 value in the traceback module.
1212
Greg Ward48fae7a2006-07-23 16:05:51 +00001213- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1214
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001215- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1216
Brett Cannoncaebe222006-07-18 04:41:36 +00001217- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1218 argument tuple. For arguments where zero is illegal, the value is forced to
1219 the minimum value that is correct. This is to support an undocumented but
1220 common way people used to fill in inconsequential information in the time
1221 tuple pre-2.4.
1222
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001223- Patch #1220874: Update the binhex module for Mach-O.
1224
Barry Warsawb110bad2006-07-21 14:51:07 +00001225- The email package has improved RFC 2231 support, specifically for
1226 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1227 (name*0=<blah>) parameter continuations. This may change the types of
1228 values returned from email.message.Message.get_param() and friends.
1229 Specifically in some cases where non-encoded continuations were used,
1230 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1231 will just return the string (since non-encoded continuations don't have
1232 charset and language parts).
1233
1234 Also, whereas % values were decoded in all parameter continuations, they are
1235 now only decoded in encoded parameter parts.
1236
Ronald Oussoren3075e162006-07-25 20:28:55 +00001237- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1238
1239- Bug #1517996: IDLE now longer shows the default Tk menu when a
1240 path browser, class browser or debugger is the frontmost window on MacOS X
1241
Barry Warsaw00decd72006-07-27 23:43:15 +00001242- Patch #1520294: Support for getset and member descriptors in types.py,
1243 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1244 of an object against these built-in types and more importantly, for getting
1245 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001248Extension Modules
1249-----------------
1250
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001251- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1252 a socket operation on a socket with a timeout, the exception will be
1253 caught correctly. Previously, the exception was not caught.
1254
Thomas Heller1393d6a2006-07-28 21:43:20 +00001255- Patch #1529514: The _ctypes extension is now compiled on more
1256 openbsd target platforms.
1257
Tim Peters9cab5932006-07-28 00:30:00 +00001258- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1259 a memory leak, affecting pickles and deep copies.
1260
Tim Petersbc24eee2006-07-27 01:14:53 +00001261- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001262 Paul Eggert.
1263
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001264- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1265
Thomas Hellerce049a02006-07-14 17:51:14 +00001266- Patch #1521817: Index range checking on ctypes arrays containing
1267 exactly one element enabled again. This allows iterating over these
1268 arrays, without the need to check the array size before.
1269
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001270- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001271 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001272 /dev/null in certain cases; this is now fixed.
1273
Thomas Heller47d7a062006-07-12 08:43:47 +00001274- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1275 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001276
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001277- Because of a misspelled preprocessor symbol, ctypes was always
1278 compiled without thread support; this is now fixed.
1279
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001280- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1281 methods now allow their database parameter to be None as the
1282 sleepycat API allows.
1283
Matt Flemingec926502006-07-28 11:27:27 +00001284- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1285 bluetooth API compared with Linux and FreeBSD.
1286
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001287Tests
1288-----
1289
1290- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1291 how long the test file should take to play. Now accepts taking 2.93 secs
1292 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1293
Georg Brandl4793aa32006-07-28 18:31:39 +00001294- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1295 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1296 run via ``regrtest.py``. Now they do.

1299-----
1300
1301- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1302
Ronald Oussoren26cad082006-08-01 21:00:57 +00001303Mac
1304---
1305
1306- PythonLauncher now works correctly when the path to the script contains
1307 characters that are treated specially by the shell (such as quotes).
1308
1309- Bug #1527397: PythonLauncher now launches scripts with the working directory
1310 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001311 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001312 expect.

1321-----------------
1322
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001323- Bug #1441486: The literal representation of -(sys.maxint - 1)
1324 again evaluates to a int object, not a long.
1325
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001326- Bug #1501934: The scope of global variables that are locally assigned
1327 using augmented assignment is now correctly determined.
1328
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001329- Bug #927248: Recursive method-wrapper objects can now safely
1330 be released.
1331
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001332- Bug #1417699: Reject locale-specific decimal point in float()
1333 and atof().
1334
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001335- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1336 omit a default "error" argument for NULL pointer. This allows
1337 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001338
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001339- Bug #1519018: 'as' is now validated properly in import statements.
1340
Neal Norwitz28746ab2006-07-09 22:14:42 +00001341- On 64 bit systems, int literals that use less than 64 bits are
1342 now ints rather than longs.
1343
Neal Norwitzed657552006-07-10 00:04:44 +00001344- Bug #1512814, Fix incorrect lineno's when code at module scope
1345 started after line 256.
1346
Tim Peters32a83612006-07-10 21:08:24 +00001347- New function ``sys._current_frames()`` returns a dict mapping thread
1348 id to topmost thread stack frame. This is for expert use, and is
1349 especially useful for debugging application deadlocks. The functionality
1350 was previously available in Fazal Majid's ``threadframe`` extension
1351 module, but it wasn't possible to do this in a wholly threadsafe way from
1352 an extension.

1361
Tim Peters32a83612006-07-10 21:08:24 +00001362- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001363 environment variable to be set in order to the SDK environment
1364 for finding the compiler, include files, etc.

1369
Thomas Woutersadd19112006-07-05 11:03:49 +00001370- string.Template() now correctly handles tuple-values. Previously,
1371 multi-value tuples would raise an exception and single-value tuples would
1372 be treated as the value they contain, instead.
1373
Martin v. Löwisede77f52006-07-03 13:01:35 +00001374- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1376
Martin v. Löwis45482392006-07-03 12:28:58 +00001377- Bug #1267547: Put proper recursive setup.py call into the
1378 spec file generated by bdist_rpm.
1379
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001380- Bug #1514693: Update turtle's heading when switching between
1381 degrees and radians.
1382
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001383- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001384 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001385
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001386- Bug #1514703: Only setup canvas window in turtle when the canvas
1387 is created.
1388
Martin v. Löwis7596e832006-07-01 15:33:37 +00001389- Bug #1513223: .close() of a _socketobj now releases the underlying
1390 socket again, which then gets closed as it becomes unreferenced.
1391
Fred Drake10497c82006-06-29 02:57:48 +00001392- Bug #1504333: Make sgmllib support angle brackets in quoted
1393 attribute values.
1394
1395- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1396 sgmllib ('[' and ']' were not accepted).
1397
Georg Brandl1be63af2006-06-28 20:23:25 +00001398- Fix a bug in the turtle module's end_fill function.
1399
Brett Cannon53ab5b72006-06-22 16:49:14 +00001400- Bug #1510580: The 'warnings' module improperly required that a Warning
1401 category be either a types.ClassType and a subclass of Warning. The proper
1402 check is just that it is a subclass with Warning as the documentation states.
1403
Georg Brandlad29e632006-06-21 17:45:17 +00001404- The compiler module now correctly compiles the new try-except-finally
1405 statement (bug #1509132).
1406
Neal Norwitz60373cd2006-06-22 06:30:50 +00001407- The wsgiref package is now installed properly on Unix.
1408
Vinay Sajip28e57612006-07-01 10:45:20 +00001409- A bug was fixed in logging.config.fileConfig() which caused a crash on
1410 shutdown when fileConfig() was called multiple times.
1411
Gerhard Häring762fbd32006-07-02 17:48:30 +00001412- The sqlite3 module did cut off data from the SQLite database at the first
1413 null character before sending it to a custom converter. This has been fixed
1414 now.
1415
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001416Extension Modules
1417-----------------
1418
Tim Peters112aad32006-07-19 00:03:19 +00001419- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1420 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1421 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001422
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001423- Assigning None to pointer type fields in ctypes structures possible
1424 overwrote the wrong fields, this is fixed now.
1425
1426- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1427 on non-Windows platforms.
1428
1429- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1430 integer or long, without range checking.
1431
1432- Patch #1517790: It is now possible to use custom objects in the ctypes
1433 foreign function argtypes sequence as long as they provide a from_param
1434 method, no longer is it required that the object is a ctypes type.
1435
1436- The '_ctypes' extension module now works when Python is configured
1437 with the --without-threads option.
1438
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001439- Bug #1513646: os.access on Windows now correctly determines write
1440 access, again.
1441
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001442- Bug #1512695: cPickle.loads could crash if it was interrupted with
1443 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001445- Bug #1296433: parsing XML with a non-default encoding and
1446 a CharacterDataHandler could crash the interpreter in pyexpat.
1447
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001448- Patch #1516912: improve Modules support for OpenVMS.

1454
Tim Peters32a83612006-07-10 21:08:24 +00001455- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001456 Previously, the slight difference could cause compilation errors of the
1457 'zlib' module on systems with more than one version of zlib.
1458
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001459- The MSI compileall step was fixed to also support a TARGETDIR
1460 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001489
1490Core and builtins
1491-----------------
1492
Georg Brandla56b9152006-06-19 06:35:54 +00001493- Patch #1507676: Error messages returned by invalid abstract object operations
1494 (such as iterating over an integer) have been improved and now include the
1495 type of the offending object to help with debugging.
1496
Brett Cannonea3912b2006-06-13 21:46:41 +00001497- Bug #992017: A classic class that defined a __coerce__() method that returned
1498 its arguments swapped would infinitely recurse and segfault the interpreter.
1499
Neal Norwitz909eb122006-06-12 02:13:21 +00001500- Fix the socket tests so they can be run concurrently.
1501
Neal Norwitzb9845e72006-06-12 02:11:18 +00001502- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001503 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001504
Brett Cannon22565aa2006-06-09 22:31:23 +00001505- Bug #532646: object.__call__() will continue looking for the __call__
1506 attribute on objects until one without one is found. This leads to recursion
1507 when you take a class and set its __call__ attribute to an instance of the
1508 class. Originally fixed for classic classes, but this fix is for new-style.
1509 Removes the infinite_rec_3 crasher.
1510
Georg Brandl24250812006-06-09 18:45:48 +00001511- The string and unicode methods startswith() and endswith() now accept
1512 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1513
Brett Cannonde3b0522006-06-08 17:00:45 +00001514- Buffer objects, at the C level, never used the char buffer
1515 implementation even when the char buffer for the wrapped object was
1516 explicitly requested (originally returned the read or write buffer).
1517 Now a TypeError is raised if the char buffer is not present but is
1518 requested.
1519
Georg Brandlddbaa662006-06-04 21:56:52 +00001520- Patch #1346214: Statements like "if 0: suite" are now again optimized
1521 away like they were in Python 2.4.
1522
Georg Brandlb7c8f542006-05-27 12:30:25 +00001523- Builtin exceptions are now full-blown new-style classes instead of
1524 instances pretending to be classes, which speeds up exception handling
1525 by about 80% in comparison to 2.5a2.
1526
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001527- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1528 Unicode 4.1.
1529
Georg Brandlf4ef1162006-05-26 18:03:31 +00001530- Patch #921466: sys.path_importer_cache is now used to cache valid and
1531 invalid file paths for the built-in import machinery which leads to
1532 fewer open calls on startup.
1533
Tim Peters696cf432006-05-24 21:10:40 +00001534- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1535 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1536 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1537 the number of input digits (it was and remains linear-time for bases
1538 2, 4, 8, 16 and 32).
1539
Tim Petersb713ec22006-05-23 18:45:30 +00001540- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1541 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1542 an integer close to ``sys.maxint``. This was repaired by patch
1543 #1335972, which also gives a nice speedup.
1544
Richard Jonescebbefc2006-05-23 18:28:17 +00001545- Patch #1337051: reduced size of frame objects.
1546
1547- PyErr_NewException now accepts a tuple of base classes as its
1548 "base" parameter.
1549
Richard Jones7c88dcc2006-05-23 10:37:38 +00001550- Patch #876206: function call speedup by retaining allocated frame
1551 objects.
1552
Georg Brandl7b90e162006-05-18 07:01:27 +00001553- Bug #1462152: file() now checks more thoroughly for invalid mode
1554 strings and removes a possible "U" before passing the mode to the
1555 C library function.
1556
Neal Norwitz1004a532006-05-15 07:17:23 +00001557- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1558
Neal Norwitz373f0a72006-05-15 07:04:36 +00001559- Bug #1487966: Fix SystemError with conditional expression in assignment
1560
Martin v. Löwis879768d2006-05-11 13:28:43 +00001561- WindowsError now has two error code attributes: errno, which carries
1562 the error values from errno.h, and winerror, which carries the error
1563 values from winerror.h. Previous versions put the winerror.h values
1564 (from GetLastError()) into the errno attribute.
1565
Martin v. Löwis77736712006-05-04 05:51:03 +00001566- Patch #1475845: Raise IndentationError for unexpected indent.
1567
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001568- Patch #1479181: split open() and file() from being aliases for each other.
1569
Tim Peters44bd9862006-06-01 13:49:23 +00001570- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1571 methods were always silently ignored by dictionaries when comparing keys.
1572 They are now passed through (except when using the C API function
1573 ``PyDict_GetItem()``, whose semantics did not change).
1574
1575- Bug #1456209: In some obscure cases it was possible for a class with a
1576 custom ``__eq__()`` method to confuse dict internals when class instances
1577 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1578 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001580Extension Modules
1581-----------------
1582
Trent Mick960a3f82006-06-28 20:30:41 +00001583- Bug #1295808: expat symbols should be namespaced in pyexpat
1584
1585- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1586
Brett Cannon6ee7d012006-06-08 16:23:04 +00001587- Change binascii.hexlify to accept a read-only buffer instead of only a char
1588 buffer and actually follow its documentation.
1589
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001590- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1591
Nick Coghlanc649ec52006-05-29 12:43:05 +00001592- Patch #1478788 (modified version): The functional extension module has
1593 been renamed to _functools and a functools Python wrapper module added.
1594 This provides a home for additional function related utilities that are
1595 not specifically about functional programming. See PEP 309.
1596
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001597- Patch #1493701: performance enhancements for struct module.
1598
Georg Brandl378d5922006-05-17 14:26:50 +00001599- Patch #1490224: time.altzone is now set correctly on Cygwin.
1600
Georg Brandl8d3342b2006-05-16 07:38:27 +00001601- Patch #1435422: zlib's compress and decompress objects now have a
1602 copy() method.
1603
Andrew MacIntyre92913322006-06-13 15:04:24 +00001604- Patch #1454481: thread stack size is now tunable at runtime for thread
1605 enabled builds on Windows and systems with Posix threads support.
1606
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001607- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1608 (up to the system limit of 32K characters).
1609
1610- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1611 As a result, these functions now raise WindowsError instead of OSError.
1612
Tim Peters7a822da2006-05-25 21:50:17 +00001613- ``time.clock()`` on Win64 should use the high-performance Windows
1614 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1615 Windows platforms).
1616
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001617- Calling Tk_Init twice is refused if the first call failed as that
1618 may deadlock.
1619
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001620- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1621 accept it without potentially using an uninitialized pointer.
1622
1623- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1624 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1625 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001626
Gregory P. Smith372b5832006-06-05 18:48:21 +00001627- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001628 [pybsddb project SF patch number 1466734]
1629
Gregory P. Smith372b5832006-06-05 18:48:21 +00001630- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1631 parameter is supplied. [SF pybsddb bug #1477863]
1632
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001633- bsddb: the __len__ method of a DB object has been fixed to return correct
1634 results. It could previously incorrectly return 0 in some cases.
1635 Fixes SF bug 1493322 (pybsddb bug 1184012).
1636
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001637- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1638 aborts the db transaction safely when a modifier callback fails.
1639 Fixes SF python patch/bug #1408584.
1640
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001641- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001642 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001643 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1644 database calls that would previously deadlock. [SF python bug #775414]
1645
Vinay Sajip28e57612006-07-01 10:45:20 +00001646- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001647
Walter Dörwald4994d952006-06-19 08:07:50 +00001648- Patch #1506645: add Python wrappers for the curses functions
1649 is_term_resized, resize_term and resizeterm.

1653
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001654- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1655 functions.
1656
Martin v. Löwis3798da02006-06-17 18:44:27 +00001657- Patch #812986: Update turtle output even if not tracing.
1658
Vinay Sajip28e57612006-07-01 10:45:20 +00001659- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001660 Tkinter.BaseWidget.
1661
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001662- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1663
Martin v. Löwis337487e2006-06-17 09:15:14 +00001664- Patch #763580: Add name and value arguments to Tkinter variable
1665 classes.
1666
Georg Brandl83cc0d02006-06-14 08:50:03 +00001667- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1668 mime.types file for determining MIME types.
1669
Georg Brandl2605ca82006-06-14 06:08:31 +00001670- Bug #1339007: Shelf objects now don't raise an exception in their
1671 __del__ method when initialization failed.
1672
Martin v. Löwisd8251432006-06-14 05:21:04 +00001673- Patch #1455898: The MBCS codec now supports the incremental mode for
1674 double-byte encodings.
1675
Tim Peters43898b42006-06-14 04:09:25 +00001676- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1677 guarantee that adjacent triples in the return list always describe
1678 non-adjacent blocks. Previously, a pair of matching blocks could end
1679 up being described by multiple adjacent triples that formed a partition
1680 of the matching pair.
1681
Greg Ward0e0c9f42006-06-11 16:24:11 +00001682- Bug #1498146: fix optparse to handle Unicode strings in option help,
1683 description, and epilog.
1684
Greg Wardd1c797e2006-06-11 14:42:41 +00001685- Bug #1366250: minor optparse documentation error.
1686
Greg Ward7f547402006-06-11 00:40:49 +00001687- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1688 clarify docs.
1689
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001690- The wsgiref package has been added to the standard library.
1691
Nick Coghlan676725d2006-06-08 13:54:49 +00001692- The functions update_wrapper() and wraps() have been added to the functools
1693 module. These make it easier to copy relevant metadata from the original
1694 function when writing wrapper functions.
1695
Tim Petersd6a9eef2006-06-05 01:48:21 +00001696- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1697 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001698
Martin v. Löwis3f767792006-06-04 19:36:28 +00001699- Patch #1359618: Speed up charmap encoder by using a trie structure
1700 for lookup.
1701
Tim Petersd609b1a2006-06-02 23:22:51 +00001702- The functions in the ``pprint`` module now sort dictionaries by key
1703 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1704 if and only if its display required more than one line, although that
1705 wasn't documented. The new behavior increases predictability; e.g.,
1706 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1707
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001708- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1709 (thanks for J. J. Lee).
1710
Georg Brandl2b330372006-05-28 20:23:12 +00001711- Patch #1496206: improve urllib2 handling of passwords with respect to
1712 default HTTP and HTTPS ports.
1713
George Yoshidaf3c65de2006-05-28 16:39:09 +00001714- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1715
Bob Ippolito7298f272006-05-23 18:43:47 +00001716- Patch #1281707: speed up gzip.readline.
1717
Georg Brandlb89316f2006-05-17 15:51:16 +00001718- Patch #1180296: Two new functions were added to the locale module:
1719 format_string() to get the effect of "format % items" but locale-aware,
1720 and currency() to format a monetary number with currency sign.
1721
Georg Brandle3a25832006-05-17 14:56:04 +00001722- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1723 and several features added, such as speed and geometry control.
1724
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001725- Patch #1488881: add support for external file objects in bz2 compressed
1726 tarfiles.
1727
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001728- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1729 stdout arguments, making it possible to redirect input and output
1730 for remote debugging.
1731
1732- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1733 a couple of issues, notably handling of long file names using the
1734 GNU LONGNAME extension.
1735
1736- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1737 new flag when ``name`` is already the name of an option flag.
1738
1739- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1740 package.
1741
1742- Patch #1472854: make the rlcompleter.Completer class usable on non-
1743 UNIX platforms.
1744
1745- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1746
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001747- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001778What's New in Python 2.5 alpha 2?
1779=================================
1780
1781*Release date: 27-APR-2006*
1782
1783Core and builtins
1784-----------------
1785
Thomas Heller1b046642006-04-18 18:51:06 +00001786- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1787 by converting these apis from macros into exported functions again:
1788
1789 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1790 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1791 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1792 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1793 PyRun_String Py_CompileString
1794
Martin v. Löwis45294a92006-04-18 06:24:08 +00001795- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1796
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001797- All uses of PyStructSequence_InitType have been changed to initialize
1798 the type objects only once, even if the interpreter is initialized
1799 multiple times.
1800
Neal Norwitz61546162006-04-14 05:20:28 +00001801- Bug #1454485, array.array('u') could crash the interpreter. This was
1802 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1803 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1804
1805- Py_UNICODE is unsigned. It was always documented as unsigned, but
1806 due to a bug had a signed value in previous versions.
1807
Tim Peters3a5e8b12006-04-11 01:44:07 +00001808- Patch #837242: ``id()`` of any Python object always gives a positive
1809 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1810 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001811 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001812 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001813
Tim Peters3a5e8b12006-04-11 01:44:07 +00001814 def __hash__(self):
1815 return id(self) # WRONG
1816
1817 because a hash result must be a (short) Python int but it was always
1818 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001819 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001820 was always usable as a hash value before this patch. That's no longer
1821 necessarily so.
1822
1823- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001824 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001825 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001826 #1454844)
1827
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001828- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1829 involving generators that have paused outside of any ``try`` or ``with``
1830 blocks. (In 2.5a1, a paused generator that was part of a reference
1831 cycle could not be garbage collected, regardless of whether it was
1832 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001833
Anthony Baxter51bcb682006-04-05 14:51:42 +00001834Extension Modules
1835-----------------
1836
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001837- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1838 is a macro.
1839
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001840- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1841 fails with an error condition.
1842
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001843- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1844
1845- Bug #1117761: bsddb.*open() no longer raises an exception when using
1846 the cachesize parameter.
1847
1848- Bug #1149413: bsddb.*open() no longer raises an exception when using
1849 a temporary db (file=None) with the 'n' flag to truncate on open.
1850
1851- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1852 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001853
Armin Rigoa9017c32006-04-19 11:50:27 +00001854- Patch #1062014: AF_UNIX sockets under Linux have a special
1855 abstract namespace that is now fully supported.
1856
Anthony Baxter51bcb682006-04-05 14:51:42 +00001857Library
1858-------
1859
Peter Astrand7d1d4362006-07-14 14:04:45 +00001860- Bug #1223937: subprocess.CalledProcessError reports the exit status
1861 of the process using the returncode attribute, instead of
1862 abusing errno.
1863
Tim Peters711bf302006-04-25 03:31:36 +00001864- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1865 a doctest to be skipped (the code is not run, and the expected output
1866 or exception is ignored).
1867
Nick Coghlanda2268f2006-04-24 04:37:15 +00001868- Fixed contextlib.nested to cope with exceptions being raised and
1869 caught inside exit handlers.
1870
Greg Wardab05edc2006-04-23 03:47:58 +00001871- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1872 hex, octal, or binary; add ``append_const`` action; keep going if
1873 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1874 added ``epilog`` for better help generation).
1875
Tim Peters21fbd572006-04-21 21:18:10 +00001876- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1877 called from a thread spawned as a side effect of importing a module.
1878
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001879- The pydoc module now supports documenting packages contained in
1880 .zip or .egg files.
1881
1882- The pkgutil module now has several new utility functions, such
1883 as ``walk_packages()`` to support working with packages that are either
1884 in the filesystem or zip files.
1885
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001886- The mailbox module can now modify and delete messages from
1887 mailboxes, in addition to simply reading them. Thanks to Gregory
1888 K. Johnson for writing the code, and to the 2005 Google Summer of
1889 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001890
Tim Petersc7605f22006-04-17 21:12:33 +00001891- The ``__del__`` method of class ``local`` in module ``_threading_local``
1892 returned before accomplishing any of its intended cleanup.
1893
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001894- Patch #790710: Add breakpoint command lists in pdb.
1895
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001896- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1897
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001898- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1899
Anthony Baxtere29002c2006-04-12 12:07:31 +00001900- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1901 Windows. Bug #1469163.
1902
Phillip J. Eby47032112006-04-11 01:07:43 +00001903- The warnings, linecache, inspect, traceback, site, and doctest modules
1904 were updated to work correctly with modules imported from zipfiles or
1905 via other PEP 302 __loader__ objects.
1906
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001907- Patch #1467770: Reduce usage of subprocess._active to processes which
1908 the application hasn't waited on.
1909
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001910- Patch #1462222: Fix Tix.Grid.
1911
Neal Norwitza31bf182006-04-09 03:35:43 +00001912- Fix exception when doing glob.glob('anything*/')
1913
Skip Montanaro262fb922006-04-21 02:31:07 +00001914- The pstats.Stats class accepts an optional stream keyword argument to
1915 direct output to an alternate file-like object.
1916
Anthony Baxter51bcb682006-04-05 14:51:42 +00001917Build
1918-----
1919
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001920- The Makefile now has a reindent target, which runs reindent.py on
1921 the library.
1922
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001923- Patch #1470875: Building Python with MS Free Compiler
1924
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001925- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001926
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001927- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1928 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001929 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001930 CXX from --with-cxx-main, see description in README.
1931
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001932- Patch #1429775: Link extension modules with the shared libpython.
1933
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001934- Fixed a libffi build problem on MIPS systems.
1935
Tim Peters8931ff12006-05-13 23:28:20 +00001936- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1937 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1938 and "%zu" for unsigned integers of type ``size_t``.
1939
Anthony Baxter51bcb682006-04-05 14:51:42 +00001940Tests
1941-----
1942
Nick Coghlanda2268f2006-04-24 04:37:15 +00001943- test_contextlib now checks contextlib.nested can cope with exceptions
1944 being raised and caught inside exit handlers.
1945
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001946- test_cmd_line now checks operation of the -m and -c command switches
1947
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001948- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1949 it separately and by hand. It also wasn't cleaning up its changes to
1950 the current Decimal context.
1951
Thomas Woutersabd08882006-04-26 15:53:30 +00001952- regrtest.py now has a -M option to run tests that test the new limits of
1953 containers, on 64-bit architectures. Running these tests is only sensible
1954 on 64-bit machines with more than two gigabytes of memory. The argument
1955 passed is the maximum amount of memory for the tests to use.
1956
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001957Tools
1958-----
1959
1960- Added the Python benchmark suite pybench to the Tools/ directory;
1961 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001963Documentation
1964-------------
1965
Tim Petersb06d28c2006-05-12 01:57:59 +00001966- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1967
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001968- PEP 343: Added Context Types section to the library reference
1969 and attempted to bring other PEP 343 related documentation into
1970 line with the implementation and/or python-dev discussions.
1971
Tim Peters8dc73d22006-04-24 02:03:16 +00001972- Bug #1337990: clarified that ``doctest`` does not support examples
1973 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001976What's New in Python 2.5 alpha 1?
1977=================================
1978
Anthony Baxterebed3f62006-04-03 15:03:44 +00001979*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001980
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001981Core and builtins
1982-----------------
1983
Nick Coghlan43832302006-04-23 17:04:07 +00001984- PEP 338: -m command line switch now delegates to runpy.run_module
1985 allowing it to support modules in packages and zipfiles
1986
Martin v. Löwisc661b882006-04-20 04:54:23 +00001987- On Windows, .DLL is not an accepted file name extension for
1988 extension modules anymore; extensions are only found if they
1989 end in .PYD.
1990
Martin v. Löwisea62d252006-04-03 10:56:49 +00001991- Bug #1421664: sys.stderr.encoding is now set to the same value as
1992 sys.stdout.encoding.
1993
Neal Norwitz92e212f2006-04-03 04:48:37 +00001994- __import__ accepts keyword arguments.
1995
Georg Brandlccadf842006-03-31 18:54:53 +00001996- Patch #1460496: round() now accepts keyword arguments.
1997
Anthony Baxter262c00a2006-03-30 10:53:17 +00001998- Fixed bug #1459029 - unicode reprs were double-escaped.
1999
Hye-Shik Changd478f342006-03-23 12:32:36 +00002000- Patch #1396919: The system scope threads are reenabled on FreeBSD
2001 5.4 and later versions.
2002
Neal Norwitze98ccf62006-03-23 05:39:47 +00002003- Bug #1115379: Compiling a Unicode string with an encoding declaration
2004 now gives a SyntaxError.
2005
Georg Brandlabd1ff82006-03-18 07:59:59 +00002006- Previously, Python code had no easy way to access the contents of a
2007 cell object. Now, a ``cell_contents`` attribute has been added
2008 (closes patch #1170323).
2009
Tim Peterscf79aac2006-03-16 01:14:46 +00002010- Patch #1123430: Python's small-object allocator now returns an arena to
2011 the system ``free()`` when all memory within an arena becomes unused
2012 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2013 freed. Some applications will see a drop in virtual memory size now,
2014 especially long-running applications that, from time to time, temporarily
2015 use a large number of small objects. Note that when Python returns an
2016 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002017 platform C library will in turn return that memory to the operating system.
2018 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002019 appears to be effective at least on Microsoft C and gcc-based systems.
2020 Thanks to Evan Jones for hard work and patience.
2021
Georg Brandl533ff6f2006-03-08 18:09:27 +00002022- Patch #1434038: property() now uses the getter's docstring if there is
2023 no "doc" argument given. This makes it possible to legitimately use
2024 property() as a decorator to produce a read-only property.
2025
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002026- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2027 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2028 of requiring an int or long in slicing and a few other contexts, enabling
2029 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2030
Neal Norwitz995acdf2006-03-07 05:01:00 +00002031- Fixed various bugs reported by Coverity's Prevent tool.
2032
Brett Cannonbf364092006-03-01 04:25:17 +00002033- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2034 new exception base class, BaseException, which has a new message attribute.
2035 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2036 Raising a string exception now raises a DeprecationWarning.
2037
Thomas Woutersfb609f42006-02-28 16:37:25 +00002038- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2039 explicitly relative, using 'from .module import name' to mean 'from the same
2040 package as this module is in. Imports without dots still default to the
2041 old relative-then-absolute, unless 'from __future__ import
2042 absolute_import' is used.
2043
Brett Cannona7446e32006-02-27 23:39:10 +00002044- Properly check if 'warnings' raises an exception (usually when a filter set
2045 to "error" is triggered) when raising a warning for raising string
2046 exceptions.
2047
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002048- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002049 The name was removed from Include/code.h.
2050
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002051- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002052
Guido van Rossum1968ad32006-02-25 22:38:04 +00002053- Patch 1433928:
2054 - The copy module now "copies" function objects (as atomic objects).
2055 - dict.__getitem__ now looks for a __missing__ hook before raising
2056 KeyError.
2057
Tim Peters84ef21c2006-02-28 20:39:06 +00002058- PEP 343: with statement implemented. Needs ``from __future__ import
2059 with_statement``. Use of 'with' as a variable will generate a warning.
2060 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002061 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002062 The following objects have __context__ methods:
2063 - The built-in file type.
2064 - The thread.LockType type.
2065 - The following types defined by the threading module:
2066 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2067 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002068
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002069- Fix the encodings package codec search function to only search
2070 inside its own package. Fixes problem reported in patch #1433198.
2071
2072 Note: Codec packages should implement and register their own
2073 codec search function. PEP 100 has the details.
2074
Tim Peters9ea89d22006-06-04 03:26:02 +00002075- PEP 353: Using ``Py_ssize_t`` as the index type.
2076
2077- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2078 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2079 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2080 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2081 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002082
Neal Norwitzfc76d632006-01-10 06:03:13 +00002083- Patch #1400181, fix unicode string formatting to not use the locale.
2084 This is how string objects work. u'%f' could use , instead of .
2085 for the decimal point. Now both strings and unicode always use periods.
2086
Neal Norwitz671b9e32006-01-09 07:07:12 +00002087- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2088 configure would break checking curses.h.
2089
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002090- Bug #959576: The pwd module is now builtin. This allows Python to be
2091 built on UNIX platforms without $HOME set.
2092
Neal Norwitzc10978f2005-12-19 06:07:16 +00002093- Bug #1072182, fix some potential problems if characters are signed.
2094
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002095- Bug #889500, fix line number on SyntaxWarning for global declarations.
2096
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002097- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2098
Neal Norwitze7214a12005-12-18 05:03:17 +00002099- Support for converting hex strings to floats no longer works.
2100 This was not portable. float('0x3') now raises a ValueError.
2101
Barry Warsaw2a38a862005-12-18 01:27:35 +00002102- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002103 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002104 is now displayed in interactive prompt banner.
2105
Georg Brandlfa166682005-12-17 21:45:17 +00002106- Implementation of PEP 341 - Unification of try/except and try/finally.
2107 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002108 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002109
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002110- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2111 now encodes backslash correctly.
2112
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002113- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2114
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002115- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002116 and long longs.
2117
Neal Norwitz67715f02005-11-09 06:59:35 +00002118- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002119 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002120 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002121
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002122- Replaced most Unicode charmap codecs with new ones using the
2123 new Unicode translate string feature in the builtin charmap
2124 codec; the codecs were created from the mapping tables available
2125 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2126 encodings now include a mapping for the Apple logo)
2127
Tim Peterse3547fd2005-12-16 23:13:57 +00002128- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002129
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002130- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002131
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002132- A new AST parser implementation was completed. The abstract
2133 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002134 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002135
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002136- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002137 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2138
Neal Norwitz708e51a2005-10-03 04:48:15 +00002139- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2140
Neal Norwitz11bd1192005-10-03 00:54:56 +00002141- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2142 Provide a warning when a directory is passed on the command line.
2143
Neal Norwitz40d37812005-10-02 01:48:49 +00002144- Fix segfault with invalid coding.
2145
2146- SF bug #772896: unknown encoding results in MemoryError.
2147
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002148- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002149 supported a __len__() method which evaluated to False when the iterator
2150 was empty.
2151
Guido van Rossum630db602005-09-20 18:49:54 +00002152- On 64-bit platforms, when __len__() returns a value that cannot be
2153 represented as a C int, raise OverflowError.
2154
Skip Montanarof8948ca2005-09-19 03:54:46 +00002155- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002156 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002157
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002158- SF bug #893549: parsing keyword arguments was broken with a few format
2159 codes.
2160
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002161- Changes donated by Elemental Security to make it work on AIX 5.3
2162 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2163 bug #105470: test_pwd fails on 64bit system (Opteron).
2164
Guido van Rossum539c6622005-09-14 17:49:54 +00002165- Changes donated by Elemental Security to make it work on HP-UX 11 on
2166 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2167
Georg Brandl4550b8d2005-08-26 06:43:52 +00002168- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002169 (fixes bug #1119418).
2170
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002171- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2172
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002173- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2174 exceptions that cause a function to exit.
2175
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002176- The implementation of set() and frozenset() was revised to use its
2177 own internal data structure. Memory consumption is reduced by 1/3
2178 and there are modest speed-ups as well. The API is unchanged.
2179
Tim Petersde7990b2005-07-17 23:45:23 +00002180- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2181
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002182- SF bug #1229429: PyObject_CallMethod failed to decrement some
2183 reference counts in some error exit cases.
2184
Tim Petersecc6e6a2005-07-10 22:30:55 +00002185- SF bug #1185883: Python's small-object memory allocator took over
2186 a block managed by the platform C library whenever a realloc specified
2187 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002188 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002189 portable way to copy data from the C-managed block into Python's
2190 small-object space without risking a memory fault. Python's small-object
2191 realloc now leaves such blocks under the control of the platform C
2192 realloc.
2193
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002194- SF bug #1232517: An overflow error was not detected properly when
2195 attempting to convert a large float to an int in os.utime().
2196
Raymond Hettinger3296e692005-06-29 23:29:56 +00002197- SF bug #1224347: hex longs now print with lowercase letters just
2198 like their int counterparts.
2199
Michael W. Hudson188d4362005-06-20 16:52:57 +00002200- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2201 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2202 interpreter states; back out that fix and do a better job (see
2203 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2204 for a longer write-up of the problem).
2205
Michael W. Hudsondf888462005-06-03 14:41:55 +00002206- SF patch #1180995: marshal now uses a binary format by default when
2207 serializing floats.
2208
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002209- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2210 the routines that promise to produce IEEE 754 binary representations
2211 of floats now simply copy bytes around.
2212
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002213- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2214 278.
2215
Brett Cannonc3647ac2005-04-26 03:45:26 +00002216- patch #1109424: int, long, float, complex, and unicode now check for the
2217 proper magic slot for type conversions when subclassed. Previously the
2218 magic slot was ignored during conversion. Semantics now match the way
2219 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002220 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002221 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002222 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002223
Barry Warsawc8d907c2005-04-19 23:43:40 +00002224- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2225 NULL, now raise an AttributeError when attempting to set or delete the
2226 attribute. Previously a TypeError was raised, but this was inconsistent
2227 with the equivalent pure-Python implementation.
2228
Michael W. Hudson774479c2005-04-18 08:46:17 +00002229- It is now safe to call PyGILState_Release() before
2230 PyEval_InitThreads() (note that if there is reason to believe there
2231 are multiple threads around you still must call PyEval_InitThreads()
2232 before using the Python API; this fix is for extension modules that
2233 have no way of knowing if Python is multi-threaded yet).
2234
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002235- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2236 disabled caused a crash.
2237
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002238- Bug #1165306: instancemethod_new allowed the creation of a method
2239 with im_class == im_self == NULL, which caused a crash when called.
2240
Tim Petersecc6e6a2005-07-10 22:30:55 +00002241- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002242 fixes the crash seen in bug #1165761
2243
Raymond Hettinger96229b12005-03-11 06:49:40 +00002244- Added two new builtins, any() and all().
2245
Brett Cannon409d8f22005-03-05 06:47:57 +00002246- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002247 (e.g., ``class C(): pass`` is no longer a syntax error).
2248 Patch #1176012 added support to the 'parser' module and 'compiler' package
2249 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002250
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002251- Patch #1115086: Support PY_LONGLONG in structmember.
2252
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002253- Bug #1155938: new style classes did not check that __init__() was
2254 returning None.
2255
Tim Petersecc6e6a2005-07-10 22:30:55 +00002256- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002257 ('\') with a specific error message.
2258
Martin v. Löwisff232d72005-03-03 09:24:38 +00002259- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2260
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002261- Bug #1124295: the __name__ attribute of file objects was
2262 inadvertently made inaccessible in restricted mode.
2263
Tim Petersecc6e6a2005-07-10 22:30:55 +00002264- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002265 an ferror() call.
2266
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002267- min() and max() now support key= arguments with the same meaning as in
2268 list.sort().
2269
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002270- The peephole optimizer now performs simple constant folding in expressions:
2271 (2+3) --> (5).
2272
Raymond Hettingera422c342005-01-11 03:03:27 +00002273- set and frozenset objects can now be marshalled. SF #1098985.
2274
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002275- Bug #1077106: Poor argument checking could cause memory corruption
2276 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002277
Jeremy Hyltonab630502005-02-04 18:44:06 +00002278- The parser did not complain about future statements in illegal
2279 positions. It once again reports a syntax error if a future
2280 statement occurs after anything other than a doc string.
2281
Neil Schemenauercf52c072005-08-12 17:34:58 +00002282- Change the %s format specifier for str objects so that it returns a
2283 unicode instance if the argument is not an instance of basestring and
2284 calling __str__ on the argument returns a unicode instance.
2285
Tim Petersf4e69282006-02-27 17:15:31 +00002286- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2287 current thread state when the auto-GIL-state machinery knows about
2288 it (since the thread state is being deleted, continuing to remember it
2289 can't help, but can hurt if another thread happens to get created with
2290 the same thread id).
2291
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002292Extension Modules
2293-----------------
2294
Georg Brandl43f08a82006-03-31 18:01:16 +00002295- Patch #1380952: fix SSL objects timing out on consecutive read()s
2296
Neal Norwitz05a45592006-03-20 06:30:08 +00002297- Patch #1309579: wait3 and wait4 were added to the posix module.
2298
Anthony Baxterfa869072006-03-20 05:21:58 +00002299- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2300 In addition, the existing ulaw code was updated.
2301
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002302- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002303 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002304
Neal Norwitz10be10c2006-03-16 06:50:13 +00002305- Everything under lib-old was removed. This includes the following modules:
2306 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002307 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002308 util, whatsound, whrandom, zmod
2309
2310- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2311
2312- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002313 is deprecated. The undocumented re.engine variable no longer exists.
2314
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002315- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002482- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2483 been renamed to have only a single underscore prefix. This was done to
2484 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002485
Nick Coghlan43832302006-04-23 17:04:07 +00002486- PEP 338: new module runpy defines a run_module function to support
2487 executing modules which provide access to source code or a code object
2488 via the PEP 302 import mechanisms.
2489
Anthony Baxter93f5b932006-04-03 08:05:07 +00002490- The email module's parsedate_tz function now sets the daylight savings

2498 in attribute values.
2499
Anthony Baxterc51ee692006-04-01 00:57:31 +00002500- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002501 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002502 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002503 module will not be built.
2504
Tim Petersc17976e2006-04-01 00:26:53 +00002505- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2506 aren't officially supported here, and trying to use them will probably
2507 raise an exception some day. But dicts have been allowed, and "mostly
2508 worked", so support for them won't go away without warning.
2509
Georg Brandl338ef7d2006-03-31 18:42:16 +00002510- Bug #1445068: getpass.getpass() can now be given an explicit stream

2528
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002529- email 4.0 package now integrated. This is largely the same as the email 3.0
2530 package that was included in Python 2.3, except that PEP 8 module names are
2531 now used (e.g. mail.message instead of email.Message). The MIME classes
2532 have been moved to a subpackage (e.g. email.mime.text instead of
2533 email.MIMEText). The old names are still supported for now. Several
2534 deprecated Message methods have been removed and lots of bugs have been
2535 fixed. More details can be found in the email package documentation.
2536
Walter Dörwald40108c92006-03-27 08:15:44 +00002537- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2538 (a subclass of tuple) that provides incremental decoders and encoders
2539 (a way to use stateful codecs without the stream API). Python functions
2540 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2541 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2542 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002544- Patch #1359365: Calling next() on a closed StringIO.String object raises
2545 a ValueError instead of a StopIteration now (like file and cString.String do).
2546 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2547 called before (like file and StringIO.StringIO do).

2615
Neal Norwitz338e7862005-12-23 21:27:46 +00002616- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2617 LoadError as documented, instead of IOError. For compatibility,
2618 LoadError subclasses IOError.
2619
Brett Cannon3cbd0382005-12-16 22:49:23 +00002620- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002621 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2622 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2623 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2624 Ronald L. Rivest offered this advice for Python:
2625
2626 "The consensus of researchers in this area (at least as
2627 expressed at the NIST Hash Function Workshop 10/31/05),
2628 is that SHA-256 is a good choice for the time being, but
2629 that research should continue, and other alternatives may
2630 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002631
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002632- Added a subset of Fredrik Lundh's ElementTree package. Available

2685 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002686 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002687

2726
Raymond Hettinger68c04532005-06-10 11:05:19 +00002727- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002728 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002729 the generate_tokens() function now accepts a callable argument that
2730 terminates by raising StopIteration.
2731
Georg Brandl9166e1a2005-06-04 09:20:03 +00002732- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2751 work as expected.
2752
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002753- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002791- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2792 disables recursive traversal through instance attributes, which can
2793 be exploited in various ways.
2794
Tim Peterse3547fd2005-12-16 23:13:57 +00002795- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2809
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002810- Enhancements to the csv module:
2811
2812 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002813 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002814 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002815 + Dialect parameter parsing has been re-implemented to improve error
2816 reporting.
2817 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2818 dictates.
2819 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002820 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002821 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002822 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2823 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002824 + reader now allows \r characters to be quoted (previously it only allowed
2825 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002826 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002827 + Dialect classes passed to the module are no longer instantiated by
2828 the module before being parsed (the former validation scheme required
2829 this, but the mechanism was unreliable).
2830 + The dialect registry now contains instances of the internal
2831 C-coded dialect type, rather than references to python objects.
2832 + the internal c-coded dialect type is now immutable.
2833 + register_dialect now accepts the same keyword dialect specifications
2834 as the reader and writer, allowing the user to register dialects
2835 without first creating a dialect class.
2836 + a configurable limit to the size of parsed fields has been added -
2837 previously, an unmatched quote character could result in the entire
2838 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002839 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002840 the parser field size limit (returning the former limit). The initial
2841 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002842 + A line_num attribute has been added to the reader object, which tracks
2843 the number of lines read from the source iterator. This is not
2844 the same as the number of records returned, as records can span
2845 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002846 + reader and writer objects were not being registered with the cyclic-GC.
2847 This has been fixed.
2848
Brett Cannone6539c42005-01-08 02:43:53 +00002849- _DummyThread objects in the threading module now delete self.__block that is
2850 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2851 lock primitives tend to be limited in number and thus should not be wasted on
2852 a _DummyThread object. Fixes bug #1089632.
2853
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002854- The imghdr module now detects Exif files.
2855
Raymond Hettinger6065d322004-12-20 23:51:53 +00002856- StringIO.truncate() now correctly adjusts the size attribute.
2857 (Bug #951915).
2858
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002859- locale.py now uses an updated locale alias table (built using
2860 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2861 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002862 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002863
Raymond Hettinger3557f422004-12-07 12:02:02 +00002864- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2865
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002866- the pickle module no longer accepts the deprecated None option in the
2867 args tuple returned by __reduce__().
2868
Brett Cannon84667c02004-12-07 03:25:18 +00002869- optparse now optionally imports gettext. This allows its use in setup.py.
2870
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002871- the pickle module no longer uses the deprecated bin parameter.
2872
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002873- the shelve module no longer uses the deprecated binary parameter.
2874
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002875- the pstats module no longer uses the deprecated ignore() method.
2876
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002877- the filecmp module no longer uses the deprecated use_statcache argument.
2878
Raymond Hettinger664347b2004-12-04 21:21:53 +00002879- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2880 extended or overridden by subclasses. Formerly, the subclassed method would
2881 be ignored by the rest of the module. (Bug #1078905).
2882
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002883- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002884 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002885
Walter Dörwald36733692004-12-22 12:50:50 +00002886- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2887 once when a size argument is given. This prevents a buffer overflow in the
2888 tokenizer with very long source lines.
2889
Barry Warsaw538561e2006-01-01 21:48:54 +00002890- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2891 immediately after creating the object, without any intervening
2892 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002893
Skip Montanaro05885812005-01-16 20:48:27 +00002894- The reconvert.quote function can now emit triple-quoted strings. The
2895 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002896
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002897- ``UserString.MutableString`` now supports negative indices in
2898 ``__setitem__`` and ``__delitem__``
2899
Greg Ward40407942005-03-05 02:53:17 +00002900- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2901 correctly.
2902
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002903- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2904 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2905 character even if the user has passed a size parameter to get a proper
2906 line ending. Remove the special handling of a "\r\n" that has been split
2907 between two lines.
2908
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002909- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2910 about illegal code points. The codec now supports PEP 293 style error
2911 handlers.
2912
Walter Dörwald78a78b02005-09-01 12:04:29 +00002913- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002914 from the input stream, so that the output is a byte string in the correct
2915 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002916
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002917- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2918 considering it exactly like a '*'.
2919
Walter Dörwald007f8df2005-10-09 19:42:27 +00002920- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2921 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002922
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002923- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2924
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002925- Patch #1413711: Certain patterns of differences were making difflib
2926 touch the recursion limit.
2927
Walter Dörwald58917a62006-03-31 15:26:22 +00002928- Bug #947906: An object oriented interface has been added to the calendar
2929 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002930 called as a script (e.g. via ``python -mcalendar``). Localized month and
2931 weekday names can be ouput (even if an exotic encoding is used) using
2932 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002933
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002934Build
2935-----
2936
Neal Norwitz602d3392006-03-31 08:21:40 +00002937- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2938 by using -mieee gcc option.
2939
Martin v. Löwis86d66262006-02-17 08:40:11 +00002940- Patch #1432345: Make python compile on DragonFly.
2941
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002942- Build support for Win64-AMD64 was added.
2943
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002944- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2945
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002946- Patch #881820: look for openpty and forkpty also in libbsd.
2947
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002948- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2949 The zlib module is now builtin on Windows.
2950
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002951- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2952
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002953- Bug #1189330: configure did not correctly determine the necessary
2954 value of LINKCC if python was built with GCC 4.0.
2955
Trent Mick8321b422005-07-26 02:29:21 +00002956- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2957 vulnerability in zlib 1.2.1 and 1.2.2.
2958
Brett Cannon08cd5982005-04-24 22:26:38 +00002959- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2960 flags that change binary compatibility. Changes were also made to
2961 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002962 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002963
Bob Ippolitoed233462005-03-29 13:47:59 +00002964- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2965 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2966 no longer exists). This configure patch makes things right.
2967
Martin v. Löwise2713be2005-03-08 15:03:08 +00002968- Bug #1158607: Build with --disable-unicode again.
2969
Brett Cannon46d96232005-02-16 00:07:19 +00002970- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2971 defined. Discovered as a result of not being able to build on OS X.
2972
Brett Cannon516592f2004-12-07 00:42:59 +00002973- setup.py now uses the directories specified in LDFLAGS using the -L option
2974 and in CPPFLAGS using the -I option for adding library and include
2975 directories, respectively, for compiling extension modules against. This has
2976 led to the core being compiled using the values in CPPFLAGS. It also removes
2977 the need for the special-casing of both DarwinPorts and Fink for darwin since
2978 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2979 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2980 Fink, ``-I/opt/local/include`` for DarwinPorts).
2981
Brett Cannon43802422005-02-10 20:48:03 +00002982- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2983 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2984 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2985 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002987C API
2988-----
2989
Tim Petersc9d78aa2006-03-26 23:27:58 +00002990- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2991 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2992 is obtained via the ``PyObject_`` family, it must be released via the
2993 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2994 always been officially true, but when Python's small-object allocator was
2995 introduced, an attempt was made to cater to a few extension modules
2996 discovered at the time that obtained memory via ``PyObject_New`` but
2997 released it via ``PyMem_DEL``. It's years later, and if such code still
2998 exists it will fail now (probably with segfaults, but calling wrong
2999 low-level memory management functions can yield many symptoms).
3000
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003001- Added a C API for set and frozenset objects.
3002

3004
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003005- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3006 mapping argument now. This string is used as a mapping table. Byte values
3007 greater than the length of the string and 0xFFFE are treated as undefined
3008 mappings.
