Andrew M. Kuchling830358a2006-11-17 16:16:28 +0000616- mailbox.py: Change MH.pack() to not lock individual message files; this

719
Brett Cannon19d76c52006-09-09 07:18:44 +0000720- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

856Core and builtins
857-----------------
858
Neal Norwitz24b6f202006-09-05 04:43:56 +0000859- Fix infinite recursion when subclassing long and overriding __hash__.
860
861- Fix concatenation (+=) of long strings.
862
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000863- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000864 compared equal or unequal to a string and a UnicodeDecodeError
865 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000866
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000867 Instead, the equal (==) and unequal (!=) comparison operators will
868 now issue a UnicodeWarning and interpret the two objects as
869 unequal. The UnicodeWarning can be filtered as desired using
870 the warning framework, e.g. silenced completely, turned into an
871 exception, logged, etc.
872
873 Note that compare operators other than equal and unequal will still
874 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000875

883
884- Patch #1538606, Fix __index__() clipping. There were some problems
885 discovered with the API and how integers that didn't fit into Py_ssize_t
886 were handled. This patch attempts to provide enough alternatives
887 to effectively use __index__.
888
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000889- Bug #1536021: __hash__ may now return long int; the final hash
890 value is obtained by invoking hash on the long int.
891
Thomas Hellerab1049c2006-08-08 17:37:00 +0000892- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000894- Bug #1535165: fixed a segfault in input() and raw_input() when
895 sys.stdin is closed.
896
Thomas Heller74d36f02006-08-04 18:17:40 +0000897- On Windows, the PyErr_Warn function is now exported from
898 the Python dll again.
899
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000900- Bug #1191458: tracing over for loops now produces a line event
901 on each iteration. Fixing this problem required changing the .pyc
902 magic number. This means that .pyc files generated before 2.5c1
903 will be regenerated.
904
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000905- Bug #1333982: string/number constants were inappropriately stored
906 in the byte code and co_consts even if they were not used, ie
907 immediately popped off the stack.
908
Georg Brandle9462c72006-08-04 18:03:37 +0000909- Fixed a reference-counting problem in property().

912Library
913-------
914
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000915- Fix a bug in the ``compiler`` package that caused invalid code to be
916 generated for generator expressions.
917
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000918- The distutils version has been changed to 2.5.0. The change to
919 keep it programmatically in sync with the Python version running
920 the code (introduced in 2.5b3) has been reverted. It will continue
921 to be maintained manually as static string literal.
922
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000923- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000924 and this cannot be converted to the required C type, an exception is
925 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000926 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000927
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000928- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000929 an exception.
930
Tim Peterscbdd3502006-09-05 01:47:53 +0000931- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000932 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000933 workarounds for clocks with low resolution, to stop the code yielding
934 duplicate UUIDs.
935
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000936- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
937 before raising SystemExit, allowing IDLE to honor quit() and exit().
938
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000939- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
940
Georg Brandl7a1af772006-08-14 21:55:28 +0000941- Patch #1536071: trace.py should now find the full module name of a
942 file correctly even on Windows.
943
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000944- logging's atexit hook now runs even if the rest of the module has
945 already been cleaned up.
946
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000947- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000948
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000949- Bug #1531405, format_exception no longer raises an exception if
950 str(exception) raised an exception.
951
Neil Schemenauer06ded092006-08-04 16:20:30 +0000952- Fix a bug in the ``compiler`` package that caused invalid code to be
953 generated for nested functions.

964 raises the correct exceptions.
965
Thomas Heller1ce433e2006-08-14 16:20:04 +0000966- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
967 '-no-stack-protector' compiler flag for OpenBSD has been removed.
968
Thomas Heller86720042006-08-14 11:17:48 +0000969- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
970 uses the _as_parameter_ attribute when objects are passed to foreign
971 function calls. The ctypes version number was changed to 1.0.1.
972
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000973- Bug #1530559, struct.pack raises TypeError where it used to convert.
974 Passing float arguments to struct.pack when integers are expected
975 now triggers a DeprecationWarning.
976
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000977

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001001- Bug #1535502, build _hashlib on Windows, and use masm assembler
1002 code in OpenSSL.
1003
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001004- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1005
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001006- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001007

Tim Peters4643c2f2006-08-10 22:45:34 +00001009C API
1010-----
1011
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001012- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1013
Tim Peters4643c2f2006-08-10 22:45:34 +00001014- Bug #1069160. Internal correctness changes were made to
1015 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1016 the documentation was changed to state that the return value
1017 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001020What's New in Python 2.5 beta 3?
1021================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001022
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001023*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001024
1025Core and builtins
1026-----------------
1027
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001028- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001029 returned a long (see PEP 353).
1030
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001031- Bug #1515471: string.replace() accepts character buffers again.
1032
Neal Norwitz07aadb12006-07-30 06:55:48 +00001033- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1034 This provides the proper warning for struct.pack().
1035 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1036
Neal Norwitz0d62a062006-07-30 06:53:31 +00001037- Patch #1531113: Fix augmented assignment with yield expressions.
1038 Also fix a SystemError when trying to assign to yield expressions.
1039
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001040- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1041 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1042 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1043 excessive filesystem operations during imports.
1044
Tim Petersbc24eee2006-07-27 01:14:53 +00001045- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1046 operations on signed longs that are formally undefined by C.
1047 Unfortunately, at least one compiler now cares about that, so complicated
1048 the code to make that compiler happy again.
1049
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001050- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1051
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001052- Patch #1232023: Stop including current directory in search
1053 path on Windows.
1054
Neal Norwitze1fdb322006-07-21 05:32:28 +00001055- Fix some potential crashes found with failmalloc.
1056
Neal Norwitze7563102006-07-17 01:00:16 +00001057- Fix warnings reported by Klocwork's static analysis tool.
1058
Neal Norwitz84be93b2006-07-16 01:50:38 +00001059- Bug #1512814, Fix incorrect lineno's when code within a function
1060 had more than 255 blank lines.
1061
Georg Brandl9dceedb2006-07-12 15:31:17 +00001062- Patch #1521179: Python now accepts the standard options ``--help`` and
1063 ``--version`` as well as ``/?`` on Windows.
1064
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001065- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001066 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001067 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001068
Tim Peters112aad32006-07-19 00:03:19 +00001069- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001070 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001071 new ``sys._current_frames()`` returns a dictionary with one entry,
1072 mapping the faux "thread id" 0 to the current frame.
1073
Ronald Oussoren3075e162006-07-25 20:28:55 +00001074- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001075
Ronald Oussoren3075e162006-07-25 20:28:55 +00001076
Neal Norwitza1f10902006-07-12 07:28:29 +00001077Library
1078-------
1079
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001080- Correction of patch #1455898: In the mbcs decoder, set final=False
1081 for stream decoder, but final=True for the decode function.
1082
Georg Brandl07fec3a2006-08-01 18:49:24 +00001083- os.urandom no longer masks unrelated exceptions like SystemExit or
1084 KeyboardInterrupt.
1085
Tim Peters4643c2f2006-08-10 22:45:34 +00001086- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001087 shutil.copytree on Windows
1088
Georg Brandle34ac7c2006-07-30 11:07:23 +00001089- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1090 refers to file descriptors, not file objects.
1091
Tim Peterscbdd3502006-09-05 01:47:53 +00001092- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001093 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001094 #1513611, and probably others.
1095
Georg Brandledd9b0d2006-07-29 09:33:26 +00001096- Bug #1441397: The compiler module now recognizes module and function
1097 docstrings correctly as it did in Python 2.4.
1098
Tim Peters6f681472006-07-27 23:44:37 +00001099- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1100 lost that tests are sorted by name before being run. This rarely
1101 matters for well-written tests, but can create baffling symptoms if
1102 side effects from one test to the next affect outcomes. ``DocTestFinder``
1103 has been changed to sort the list of tests it returns.
1104
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001105- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001106 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001107
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001108- Bug #978833: Really close underlying socket in _socketobject.close.
1109
Georg Brandldb232dc2006-08-20 13:15:43 +00001110- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1111 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001112
Georg Brandlcf0c1722006-07-26 07:23:32 +00001113- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1114 to recursive calls and call it with the failing package name.
1115
Martin v. Löwis0b483032006-07-25 09:53:12 +00001116- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1117
Georg Brandlc13c34c2006-07-24 14:09:56 +00001118- Patch #1515343: Fix printing of deprecated string exceptions with a
1119 value in the traceback module.
1120
Greg Ward48fae7a2006-07-23 16:05:51 +00001121- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1122
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001123- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1124
Brett Cannoncaebe222006-07-18 04:41:36 +00001125- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1126 argument tuple. For arguments where zero is illegal, the value is forced to
1127 the minimum value that is correct. This is to support an undocumented but
1128 common way people used to fill in inconsequential information in the time
1129 tuple pre-2.4.
1130
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001131- Patch #1220874: Update the binhex module for Mach-O.
1132
Barry Warsawb110bad2006-07-21 14:51:07 +00001133- The email package has improved RFC 2231 support, specifically for
1134 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1135 (name*0=<blah>) parameter continuations. This may change the types of
1136 values returned from email.message.Message.get_param() and friends.
1137 Specifically in some cases where non-encoded continuations were used,
1138 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1139 will just return the string (since non-encoded continuations don't have
1140 charset and language parts).
1141
1142 Also, whereas % values were decoded in all parameter continuations, they are
1143 now only decoded in encoded parameter parts.
1144
Ronald Oussoren3075e162006-07-25 20:28:55 +00001145- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1146
1147- Bug #1517996: IDLE now longer shows the default Tk menu when a
1148 path browser, class browser or debugger is the frontmost window on MacOS X
1149
Barry Warsaw00decd72006-07-27 23:43:15 +00001150- Patch #1520294: Support for getset and member descriptors in types.py,
1151 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1152 of an object against these built-in types and more importantly, for getting
1153 their docstrings printed in the interactive interpreter's help() function.

1158
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001159- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1160 a socket operation on a socket with a timeout, the exception will be
1161 caught correctly. Previously, the exception was not caught.
1162
Thomas Heller1393d6a2006-07-28 21:43:20 +00001163- Patch #1529514: The _ctypes extension is now compiled on more
1164 openbsd target platforms.
1165
Tim Peters9cab5932006-07-28 00:30:00 +00001166- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1167 a memory leak, affecting pickles and deep copies.
1168
Tim Petersbc24eee2006-07-27 01:14:53 +00001169- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1173
Thomas Hellerce049a02006-07-14 17:51:14 +00001174- Patch #1521817: Index range checking on ctypes arrays containing
1175 exactly one element enabled again. This allows iterating over these
1176 arrays, without the need to check the array size before.
1177
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001178- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001179 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001180 /dev/null in certain cases; this is now fixed.
1181
Thomas Heller47d7a062006-07-12 08:43:47 +00001182- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1183 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001184
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001185- Because of a misspelled preprocessor symbol, ctypes was always
1186 compiled without thread support; this is now fixed.
1187
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001188- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1189 methods now allow their database parameter to be None as the
1190 sleepycat API allows.
1191
Matt Flemingec926502006-07-28 11:27:27 +00001192- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1193 bluetooth API compared with Linux and FreeBSD.
1194
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001195Tests
1196-----
1197
1198- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1199 how long the test file should take to play. Now accepts taking 2.93 secs
1200 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1201
Georg Brandl4793aa32006-07-28 18:31:39 +00001202- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1203 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1204 run via ``regrtest.py``. Now they do.

1208
1209- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1210
Ronald Oussoren26cad082006-08-01 21:00:57 +00001211Mac
1212---
1213
1214- PythonLauncher now works correctly when the path to the script contains
1215 characters that are treated specially by the shell (such as quotes).
1216
1217- Bug #1527397: PythonLauncher now launches scripts with the working directory
1218 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001219 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001220 expect.

1228Core and builtins
1229-----------------
1230
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001231- Bug #1441486: The literal representation of -(sys.maxint - 1)
1232 again evaluates to a int object, not a long.
1233
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001234- Bug #1501934: The scope of global variables that are locally assigned
1235 using augmented assignment is now correctly determined.
1236
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001237- Bug #927248: Recursive method-wrapper objects can now safely
1238 be released.
1239
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001240- Bug #1417699: Reject locale-specific decimal point in float()
1241 and atof().
1242
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001243- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1244 omit a default "error" argument for NULL pointer. This allows
1245 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001246
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001247- Bug #1519018: 'as' is now validated properly in import statements.
1248
Neal Norwitz28746ab2006-07-09 22:14:42 +00001249- On 64 bit systems, int literals that use less than 64 bits are
1250 now ints rather than longs.
1251
Neal Norwitzed657552006-07-10 00:04:44 +00001252- Bug #1512814, Fix incorrect lineno's when code at module scope
1253 started after line 256.
1254
Tim Peters32a83612006-07-10 21:08:24 +00001255- New function ``sys._current_frames()`` returns a dict mapping thread
1256 id to topmost thread stack frame. This is for expert use, and is
1257 especially useful for debugging application deadlocks. The functionality
1258 was previously available in Fazal Majid's ``threadframe`` extension
1259 module, but it wasn't possible to do this in a wholly threadsafe way from
1260 an extension.
1261

Martin v. Löwis77621582006-07-30 13:27:31 +00001265- Bug #1257728: Mention Cygwin in distutils error message about a missing
1266 VS 2003.
1267
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001268- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1269
Tim Peters32a83612006-07-10 21:08:24 +00001270- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001271 environment variable to be set in order to the SDK environment
1272 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001276- warnings.py now ignores ImportWarning by default
1277
Thomas Woutersadd19112006-07-05 11:03:49 +00001278- string.Template() now correctly handles tuple-values. Previously,
1279 multi-value tuples would raise an exception and single-value tuples would
1280 be treated as the value they contain, instead.
1281
Martin v. Löwisede77f52006-07-03 13:01:35 +00001282- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1283 even if some data are received.
1284
Martin v. Löwis45482392006-07-03 12:28:58 +00001285- Bug #1267547: Put proper recursive setup.py call into the
1286 spec file generated by bdist_rpm.
1287
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001288- Bug #1514693: Update turtle's heading when switching between
1289 degrees and radians.
1290
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001291- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001292 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001293
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001294- Bug #1514703: Only setup canvas window in turtle when the canvas
1295 is created.
1296
Martin v. Löwis7596e832006-07-01 15:33:37 +00001297- Bug #1513223: .close() of a _socketobj now releases the underlying
1298 socket again, which then gets closed as it becomes unreferenced.

1301 attribute values.
1302
1303- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1304 sgmllib ('[' and ']' were not accepted).
1305
Georg Brandl1be63af2006-06-28 20:23:25 +00001306- Fix a bug in the turtle module's end_fill function.
1307
Brett Cannon53ab5b72006-06-22 16:49:14 +00001308- Bug #1510580: The 'warnings' module improperly required that a Warning
1309 category be either a types.ClassType and a subclass of Warning. The proper
1310 check is just that it is a subclass with Warning as the documentation states.
1311
Georg Brandlad29e632006-06-21 17:45:17 +00001312- The compiler module now correctly compiles the new try-except-finally
1313 statement (bug #1509132).
1314
Neal Norwitz60373cd2006-06-22 06:30:50 +00001315- The wsgiref package is now installed properly on Unix.
1316
Vinay Sajip28e57612006-07-01 10:45:20 +00001317- A bug was fixed in logging.config.fileConfig() which caused a crash on
1318 shutdown when fileConfig() was called multiple times.
1319
Gerhard Häring762fbd32006-07-02 17:48:30 +00001320- The sqlite3 module did cut off data from the SQLite database at the first
1321 null character before sending it to a custom converter. This has been fixed
1322 now.
1323
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001324Extension Modules
1325-----------------
1326
Tim Peters112aad32006-07-19 00:03:19 +00001327- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1328 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1329 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001330
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001331- Assigning None to pointer type fields in ctypes structures possible
1332 overwrote the wrong fields, this is fixed now.
1333
1334- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1335 on non-Windows platforms.
1336
1337- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1338 integer or long, without range checking.
1339
1340- Patch #1517790: It is now possible to use custom objects in the ctypes
1341 foreign function argtypes sequence as long as they provide a from_param
1342 method, no longer is it required that the object is a ctypes type.
1343
1344- The '_ctypes' extension module now works when Python is configured
1345 with the --without-threads option.
1346
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001347- Bug #1513646: os.access on Windows now correctly determines write
1348 access, again.
1349
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001350- Bug #1512695: cPickle.loads could crash if it was interrupted with
1351 a KeyboardInterrupt.
1352
Neal Norwitza12aa882006-07-06 06:45:08 +00001353- Bug #1296433: parsing XML with a non-default encoding and
1354 a CharacterDataHandler could crash the interpreter in pyexpat.
1355
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001356- Patch #1516912: improve Modules support for OpenVMS.
1357
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001358Build
1359-----
1360
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001361- Automate Windows build process for the Win64 SSL module.
1362
Tim Peters32a83612006-07-10 21:08:24 +00001363- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001364 Previously, the slight difference could cause compilation errors of the
1365 'zlib' module on systems with more than one version of zlib.
1366
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001367- The MSI compileall step was fixed to also support a TARGETDIR
1368 with spaces in it.
1369
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001370- Bug #1517388: sqlite3.dll is now installed on Windows independent
1371 of Tcl/Tk.
1372
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001373- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001374 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001376Tests
1377-----
1378
1379- Call os.waitpid() at the end of tests that spawn child processes in order
1380 to minimize resources (zombies).
1381
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001382Documentation
1383-------------
1384
Nick Coghlan2d792252006-07-06 13:47:18 +00001385- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1386 documentation for the warnings module.
1387
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001388- Patch #1509163: MS Toolkit Compiler no longer available.
1389

Anthony Baxter51bcb682006-04-05 14:51:42 +00001397
1398Core and builtins
1399-----------------
1400
Georg Brandla56b9152006-06-19 06:35:54 +00001401- Patch #1507676: Error messages returned by invalid abstract object operations
1402 (such as iterating over an integer) have been improved and now include the
1403 type of the offending object to help with debugging.
1404
Brett Cannonea3912b2006-06-13 21:46:41 +00001405- Bug #992017: A classic class that defined a __coerce__() method that returned
1406 its arguments swapped would infinitely recurse and segfault the interpreter.
1407
Neal Norwitz909eb122006-06-12 02:13:21 +00001408- Fix the socket tests so they can be run concurrently.
1409
Neal Norwitzb9845e72006-06-12 02:11:18 +00001410- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001411 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001412
Brett Cannon22565aa2006-06-09 22:31:23 +00001413- Bug #532646: object.__call__() will continue looking for the __call__
1414 attribute on objects until one without one is found. This leads to recursion
1415 when you take a class and set its __call__ attribute to an instance of the
1416 class. Originally fixed for classic classes, but this fix is for new-style.
1417 Removes the infinite_rec_3 crasher.
1418
Georg Brandl24250812006-06-09 18:45:48 +00001419- The string and unicode methods startswith() and endswith() now accept
1420 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1421
Brett Cannonde3b0522006-06-08 17:00:45 +00001422- Buffer objects, at the C level, never used the char buffer
1423 implementation even when the char buffer for the wrapped object was
1424 explicitly requested (originally returned the read or write buffer).
1425 Now a TypeError is raised if the char buffer is not present but is
1426 requested.
1427
Georg Brandlddbaa662006-06-04 21:56:52 +00001428- Patch #1346214: Statements like "if 0: suite" are now again optimized
1429 away like they were in Python 2.4.
1430
Georg Brandlb7c8f542006-05-27 12:30:25 +00001431- Builtin exceptions are now full-blown new-style classes instead of
1432 instances pretending to be classes, which speeds up exception handling
1433 by about 80% in comparison to 2.5a2.
1434
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001435- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1436 Unicode 4.1.
1437
Georg Brandlf4ef1162006-05-26 18:03:31 +00001438- Patch #921466: sys.path_importer_cache is now used to cache valid and
1439 invalid file paths for the built-in import machinery which leads to
1440 fewer open calls on startup.
1441
Tim Peters696cf432006-05-24 21:10:40 +00001442- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1443 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1444 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1445 the number of input digits (it was and remains linear-time for bases
1446 2, 4, 8, 16 and 32).
1447
Tim Petersb713ec22006-05-23 18:45:30 +00001448- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1449 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1450 an integer close to ``sys.maxint``. This was repaired by patch
1451 #1335972, which also gives a nice speedup.
1452
Richard Jonescebbefc2006-05-23 18:28:17 +00001453- Patch #1337051: reduced size of frame objects.
1454
1455- PyErr_NewException now accepts a tuple of base classes as its
1456 "base" parameter.
1457
Richard Jones7c88dcc2006-05-23 10:37:38 +00001458- Patch #876206: function call speedup by retaining allocated frame
1459 objects.
1460
Georg Brandl7b90e162006-05-18 07:01:27 +00001461- Bug #1462152: file() now checks more thoroughly for invalid mode
1462 strings and removes a possible "U" before passing the mode to the
1463 C library function.
1464
Neal Norwitz1004a532006-05-15 07:17:23 +00001465- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1466
Neal Norwitz373f0a72006-05-15 07:04:36 +00001467- Bug #1487966: Fix SystemError with conditional expression in assignment
1468
Martin v. Löwis879768d2006-05-11 13:28:43 +00001469- WindowsError now has two error code attributes: errno, which carries
1470 the error values from errno.h, and winerror, which carries the error
1471 values from winerror.h. Previous versions put the winerror.h values
1472 (from GetLastError()) into the errno attribute.
1473
Martin v. Löwis77736712006-05-04 05:51:03 +00001474- Patch #1475845: Raise IndentationError for unexpected indent.
1475
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001476- Patch #1479181: split open() and file() from being aliases for each other.
1477
Tim Peters44bd9862006-06-01 13:49:23 +00001478- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1479 methods were always silently ignored by dictionaries when comparing keys.
1480 They are now passed through (except when using the C API function
1481 ``PyDict_GetItem()``, whose semantics did not change).
1482
1483- Bug #1456209: In some obscure cases it was possible for a class with a
1484 custom ``__eq__()`` method to confuse dict internals when class instances
1485 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1486 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001488Extension Modules
1489-----------------
1490
Trent Mick960a3f82006-06-28 20:30:41 +00001491- Bug #1295808: expat symbols should be namespaced in pyexpat
1492
1493- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1494
Brett Cannon6ee7d012006-06-08 16:23:04 +00001495- Change binascii.hexlify to accept a read-only buffer instead of only a char
1496 buffer and actually follow its documentation.
1497
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001498- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1499
Nick Coghlanc649ec52006-05-29 12:43:05 +00001500- Patch #1478788 (modified version): The functional extension module has
1501 been renamed to _functools and a functools Python wrapper module added.
1502 This provides a home for additional function related utilities that are
1503 not specifically about functional programming. See PEP 309.
1504
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001505- Patch #1493701: performance enhancements for struct module.
1506
Georg Brandl378d5922006-05-17 14:26:50 +00001507- Patch #1490224: time.altzone is now set correctly on Cygwin.
1508
Georg Brandl8d3342b2006-05-16 07:38:27 +00001509- Patch #1435422: zlib's compress and decompress objects now have a
1510 copy() method.
1511
Andrew MacIntyre92913322006-06-13 15:04:24 +00001512- Patch #1454481: thread stack size is now tunable at runtime for thread
1513 enabled builds on Windows and systems with Posix threads support.
1514
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001515- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1516 (up to the system limit of 32K characters).
1517
1518- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1519 As a result, these functions now raise WindowsError instead of OSError.
1520
Tim Peters7a822da2006-05-25 21:50:17 +00001521- ``time.clock()`` on Win64 should use the high-performance Windows
1522 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1523 Windows platforms).
1524
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001525- Calling Tk_Init twice is refused if the first call failed as that
1526 may deadlock.
1527
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001528- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1529 accept it without potentially using an uninitialized pointer.
1530
1531- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1532 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1533 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001534
Gregory P. Smith372b5832006-06-05 18:48:21 +00001535- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001536 [pybsddb project SF patch number 1466734]
1537
Gregory P. Smith372b5832006-06-05 18:48:21 +00001538- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1539 parameter is supplied. [SF pybsddb bug #1477863]
1540
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001541- bsddb: the __len__ method of a DB object has been fixed to return correct
1542 results. It could previously incorrectly return 0 in some cases.
1543 Fixes SF bug 1493322 (pybsddb bug 1184012).
1544
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001545- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1546 aborts the db transaction safely when a modifier callback fails.
1547 Fixes SF python patch/bug #1408584.
1548
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001549- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001550 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001551 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1552 database calls that would previously deadlock. [SF python bug #775414]
1553
Vinay Sajip28e57612006-07-01 10:45:20 +00001554- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001555
Walter Dörwald4994d952006-06-19 08:07:50 +00001556- Patch #1506645: add Python wrappers for the curses functions
1557 is_term_resized, resize_term and resizeterm.

1563 functions.
1564
Martin v. Löwis3798da02006-06-17 18:44:27 +00001565- Patch #812986: Update turtle output even if not tracing.
1566
Vinay Sajip28e57612006-07-01 10:45:20 +00001567- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001568 Tkinter.BaseWidget.
1569
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001570- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

Martin v. Löwis337487e2006-06-17 09:15:14 +00001572- Patch #763580: Add name and value arguments to Tkinter variable
1573 classes.
1574
Georg Brandl83cc0d02006-06-14 08:50:03 +00001575- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1576 mime.types file for determining MIME types.
1577
Georg Brandl2605ca82006-06-14 06:08:31 +00001578- Bug #1339007: Shelf objects now don't raise an exception in their
1579 __del__ method when initialization failed.
1580
Martin v. Löwisd8251432006-06-14 05:21:04 +00001581- Patch #1455898: The MBCS codec now supports the incremental mode for
1582 double-byte encodings.
1583
Tim Peters43898b42006-06-14 04:09:25 +00001584- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1585 guarantee that adjacent triples in the return list always describe
1586 non-adjacent blocks. Previously, a pair of matching blocks could end
1587 up being described by multiple adjacent triples that formed a partition
1588 of the matching pair.
1589
Greg Ward0e0c9f42006-06-11 16:24:11 +00001590- Bug #1498146: fix optparse to handle Unicode strings in option help,
1591 description, and epilog.
1592
Greg Wardd1c797e2006-06-11 14:42:41 +00001593- Bug #1366250: minor optparse documentation error.
1594
Greg Ward7f547402006-06-11 00:40:49 +00001595- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1596 clarify docs.
1597
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001598- The wsgiref package has been added to the standard library.
1599
Nick Coghlan676725d2006-06-08 13:54:49 +00001600- The functions update_wrapper() and wraps() have been added to the functools
1601 module. These make it easier to copy relevant metadata from the original
1602 function when writing wrapper functions.
1603
Tim Petersd6a9eef2006-06-05 01:48:21 +00001604- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1605 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001606
Martin v. Löwis3f767792006-06-04 19:36:28 +00001607- Patch #1359618: Speed up charmap encoder by using a trie structure
1608 for lookup.
1609
Tim Petersd609b1a2006-06-02 23:22:51 +00001610- The functions in the ``pprint`` module now sort dictionaries by key
1611 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1612 if and only if its display required more than one line, although that
1613 wasn't documented. The new behavior increases predictability; e.g.,
1614 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1615
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001616- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1617 (thanks for J. J. Lee).
1618
Georg Brandl2b330372006-05-28 20:23:12 +00001619- Patch #1496206: improve urllib2 handling of passwords with respect to
1620 default HTTP and HTTPS ports.
1621
George Yoshidaf3c65de2006-05-28 16:39:09 +00001622- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1623
Bob Ippolito7298f272006-05-23 18:43:47 +00001624- Patch #1281707: speed up gzip.readline.
1625
Georg Brandlb89316f2006-05-17 15:51:16 +00001626- Patch #1180296: Two new functions were added to the locale module:
1627 format_string() to get the effect of "format % items" but locale-aware,
1628 and currency() to format a monetary number with currency sign.
1629
Georg Brandle3a25832006-05-17 14:56:04 +00001630- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1631 and several features added, such as speed and geometry control.
1632
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001633- Patch #1488881: add support for external file objects in bz2 compressed
1634 tarfiles.
1635
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001636- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1637 stdout arguments, making it possible to redirect input and output
1638 for remote debugging.
1639
1640- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1641 a couple of issues, notably handling of long file names using the
1642 GNU LONGNAME extension.
1643
1644- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1645 new flag when ``name`` is already the name of an option flag.
1646
1647- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1648 package.
1649
1650- Patch #1472854: make the rlcompleter.Completer class usable on non-
1651 UNIX platforms.
1652
1653- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1654
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001655- Bug #1472827: correctly escape newlines and tabs in attribute values in
1656 the saxutils.XMLGenerator class.

1691Core and builtins
1692-----------------
1693
Thomas Heller1b046642006-04-18 18:51:06 +00001694- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1695 by converting these apis from macros into exported functions again:
1696
1697 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1698 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1699 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1700 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1701 PyRun_String Py_CompileString
1702
Martin v. Löwis45294a92006-04-18 06:24:08 +00001703- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1704
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001705- All uses of PyStructSequence_InitType have been changed to initialize
1706 the type objects only once, even if the interpreter is initialized
1707 multiple times.
1708
Neal Norwitz61546162006-04-14 05:20:28 +00001709- Bug #1454485, array.array('u') could crash the interpreter. This was
1710 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1711 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1712
1713- Py_UNICODE is unsigned. It was always documented as unsigned, but
1714 due to a bug had a signed value in previous versions.
1715
Tim Peters3a5e8b12006-04-11 01:44:07 +00001716- Patch #837242: ``id()`` of any Python object always gives a positive
1717 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1718 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001719 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001720 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001721
Tim Peters3a5e8b12006-04-11 01:44:07 +00001722 def __hash__(self):
1723 return id(self) # WRONG
1724
1725 because a hash result must be a (short) Python int but it was always
1726 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001727 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001728 was always usable as a hash value before this patch. That's no longer
1729 necessarily so.
1730
1731- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001732 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001733 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001734 #1454844)
1735
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001736- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1737 involving generators that have paused outside of any ``try`` or ``with``
1738 blocks. (In 2.5a1, a paused generator that was part of a reference
1739 cycle could not be garbage collected, regardless of whether it was
1740 paused in a ``try`` or ``with`` block.)

1747
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001748- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1749 fails with an error condition.
1750
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001751- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1752
1753- Bug #1117761: bsddb.*open() no longer raises an exception when using
1754 the cachesize parameter.
1755
1756- Bug #1149413: bsddb.*open() no longer raises an exception when using
1757 a temporary db (file=None) with the 'n' flag to truncate on open.
1758
1759- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1760 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001761
Armin Rigoa9017c32006-04-19 11:50:27 +00001762- Patch #1062014: AF_UNIX sockets under Linux have a special
1763 abstract namespace that is now fully supported.

1766-------
1767
Peter Astrand7d1d4362006-07-14 14:04:45 +00001768- Bug #1223937: subprocess.CalledProcessError reports the exit status
1769 of the process using the returncode attribute, instead of
1770 abusing errno.
1771
Tim Peters711bf302006-04-25 03:31:36 +00001772- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1773 a doctest to be skipped (the code is not run, and the expected output
1774 or exception is ignored).
1775
Nick Coghlanda2268f2006-04-24 04:37:15 +00001776- Fixed contextlib.nested to cope with exceptions being raised and
1777 caught inside exit handlers.
1778
Greg Wardab05edc2006-04-23 03:47:58 +00001779- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1780 hex, octal, or binary; add ``append_const`` action; keep going if
1781 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1782 added ``epilog`` for better help generation).
1783
Tim Peters21fbd572006-04-21 21:18:10 +00001784- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1785 called from a thread spawned as a side effect of importing a module.
1786
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001787- The pydoc module now supports documenting packages contained in
1788 .zip or .egg files.
1789
1790- The pkgutil module now has several new utility functions, such
1791 as ``walk_packages()`` to support working with packages that are either
1792 in the filesystem or zip files.
1793
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001794- The mailbox module can now modify and delete messages from
1795 mailboxes, in addition to simply reading them. Thanks to Gregory
1796 K. Johnson for writing the code, and to the 2005 Google Summer of
1797 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001798

1821
Skip Montanaro262fb922006-04-21 02:31:07 +00001822- The pstats.Stats class accepts an optional stream keyword argument to
1823 direct output to an alternate file-like object.
1824
Anthony Baxter51bcb682006-04-05 14:51:42 +00001825Build
1826-----
1827
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001828- The Makefile now has a reindent target, which runs reindent.py on
1829 the library.
1830
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001831- Patch #1470875: Building Python with MS Free Compiler
1832

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001834
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001835- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1836 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001837 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001838 CXX from --with-cxx-main, see description in README.
1839
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001840- Patch #1429775: Link extension modules with the shared libpython.
1841

1843
Tim Peters8931ff12006-05-13 23:28:20 +00001844- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1845 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1846 and "%zu" for unsigned integers of type ``size_t``.
1847
Anthony Baxter51bcb682006-04-05 14:51:42 +00001848Tests
1849-----
1850
Nick Coghlanda2268f2006-04-24 04:37:15 +00001851- test_contextlib now checks contextlib.nested can cope with exceptions
1852 being raised and caught inside exit handlers.
1853
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001854- test_cmd_line now checks operation of the -m and -c command switches
1855
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001856- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1857 it separately and by hand. It also wasn't cleaning up its changes to
1858 the current Decimal context.
1859
Thomas Woutersabd08882006-04-26 15:53:30 +00001860- regrtest.py now has a -M option to run tests that test the new limits of
1861 containers, on 64-bit architectures. Running these tests is only sensible
1862 on 64-bit machines with more than two gigabytes of memory. The argument
1863 passed is the maximum amount of memory for the tests to use.
1864
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001865Tools

1872-------------
1873
Tim Petersb06d28c2006-05-12 01:57:59 +00001874- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1875
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001876- PEP 343: Added Context Types section to the library reference
1877 and attempted to bring other PEP 343 related documentation into
1878 line with the implementation and/or python-dev discussions.
1879
Tim Peters8dc73d22006-04-24 02:03:16 +00001880- Bug #1337990: clarified that ``doctest`` does not support examples
1881 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001884What's New in Python 2.5 alpha 1?
1885=================================
1886
Anthony Baxterebed3f62006-04-03 15:03:44 +00001887*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001888
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001889Core and builtins
1890-----------------
1891
Nick Coghlan43832302006-04-23 17:04:07 +00001892- PEP 338: -m command line switch now delegates to runpy.run_module
1893 allowing it to support modules in packages and zipfiles
1894
Martin v. Löwisc661b882006-04-20 04:54:23 +00001895- On Windows, .DLL is not an accepted file name extension for
1896 extension modules anymore; extensions are only found if they
1897 end in .PYD.
1898
Martin v. Löwisea62d252006-04-03 10:56:49 +00001899- Bug #1421664: sys.stderr.encoding is now set to the same value as
1900 sys.stdout.encoding.
1901
Neal Norwitz92e212f2006-04-03 04:48:37 +00001902- __import__ accepts keyword arguments.
1903
Georg Brandlccadf842006-03-31 18:54:53 +00001904- Patch #1460496: round() now accepts keyword arguments.
1905
Anthony Baxter262c00a2006-03-30 10:53:17 +00001906- Fixed bug #1459029 - unicode reprs were double-escaped.
1907
Hye-Shik Changd478f342006-03-23 12:32:36 +00001908- Patch #1396919: The system scope threads are reenabled on FreeBSD
1909 5.4 and later versions.
1910
Neal Norwitze98ccf62006-03-23 05:39:47 +00001911- Bug #1115379: Compiling a Unicode string with an encoding declaration
1912 now gives a SyntaxError.
1913
Georg Brandlabd1ff82006-03-18 07:59:59 +00001914- Previously, Python code had no easy way to access the contents of a
1915 cell object. Now, a ``cell_contents`` attribute has been added
1916 (closes patch #1170323).
1917
Tim Peterscf79aac2006-03-16 01:14:46 +00001918- Patch #1123430: Python's small-object allocator now returns an arena to
1919 the system ``free()`` when all memory within an arena becomes unused
1920 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1921 freed. Some applications will see a drop in virtual memory size now,
1922 especially long-running applications that, from time to time, temporarily
1923 use a large number of small objects. Note that when Python returns an
1924 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001925 platform C library will in turn return that memory to the operating system.
1926 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001927 appears to be effective at least on Microsoft C and gcc-based systems.
1928 Thanks to Evan Jones for hard work and patience.
1929
Georg Brandl533ff6f2006-03-08 18:09:27 +00001930- Patch #1434038: property() now uses the getter's docstring if there is
1931 no "doc" argument given. This makes it possible to legitimately use
1932 property() as a decorator to produce a read-only property.
1933
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001934- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1935 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1936 of requiring an int or long in slicing and a few other contexts, enabling
1937 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1938
Neal Norwitz995acdf2006-03-07 05:01:00 +00001939- Fixed various bugs reported by Coverity's Prevent tool.
1940
Brett Cannonbf364092006-03-01 04:25:17 +00001941- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1942 new exception base class, BaseException, which has a new message attribute.
1943 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1944 Raising a string exception now raises a DeprecationWarning.
1945
Thomas Woutersfb609f42006-02-28 16:37:25 +00001946- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1947 explicitly relative, using 'from .module import name' to mean 'from the same
1948 package as this module is in. Imports without dots still default to the
1949 old relative-then-absolute, unless 'from __future__ import
1950 absolute_import' is used.
1951
Brett Cannona7446e32006-02-27 23:39:10 +00001952- Properly check if 'warnings' raises an exception (usually when a filter set
1953 to "error" is triggered) when raising a warning for raising string
1954 exceptions.
1955
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001956- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001957 The name was removed from Include/code.h.
1958
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001959- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001960
Guido van Rossum1968ad32006-02-25 22:38:04 +00001961- Patch 1433928:
1962 - The copy module now "copies" function objects (as atomic objects).
1963 - dict.__getitem__ now looks for a __missing__ hook before raising
1964 KeyError.
1965
Tim Peters84ef21c2006-02-28 20:39:06 +00001966- PEP 343: with statement implemented. Needs ``from __future__ import
1967 with_statement``. Use of 'with' as a variable will generate a warning.
1968 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001969 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001970 The following objects have __context__ methods:
1971 - The built-in file type.
1972 - The thread.LockType type.
1973 - The following types defined by the threading module:
1974 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1975 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001976
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001977- Fix the encodings package codec search function to only search
1978 inside its own package. Fixes problem reported in patch #1433198.
1979
1980 Note: Codec packages should implement and register their own
1981 codec search function. PEP 100 has the details.
1982
Tim Peters9ea89d22006-06-04 03:26:02 +00001983- PEP 353: Using ``Py_ssize_t`` as the index type.
1984
1985- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1986 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1987 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1988 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1989 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001990
Neal Norwitzfc76d632006-01-10 06:03:13 +00001991- Patch #1400181, fix unicode string formatting to not use the locale.
1992 This is how string objects work. u'%f' could use , instead of .
1993 for the decimal point. Now both strings and unicode always use periods.
1994
Neal Norwitz671b9e32006-01-09 07:07:12 +00001995- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1996 configure would break checking curses.h.
1997
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001998- Bug #959576: The pwd module is now builtin. This allows Python to be
1999 built on UNIX platforms without $HOME set.
2000
Neal Norwitzc10978f2005-12-19 06:07:16 +00002001- Bug #1072182, fix some potential problems if characters are signed.
2002
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002003- Bug #889500, fix line number on SyntaxWarning for global declarations.
2004
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002005- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2006
Neal Norwitze7214a12005-12-18 05:03:17 +00002007- Support for converting hex strings to floats no longer works.
2008 This was not portable. float('0x3') now raises a ValueError.
2009
Barry Warsaw2a38a862005-12-18 01:27:35 +00002010- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002011 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002012 is now displayed in interactive prompt banner.
2013
Georg Brandlfa166682005-12-17 21:45:17 +00002014- Implementation of PEP 341 - Unification of try/except and try/finally.
2015 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002016 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002017
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002018- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2019 now encodes backslash correctly.
2020
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002021- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2022
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002023- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002024 and long longs.
2025
Neal Norwitz67715f02005-11-09 06:59:35 +00002026- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002027 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002028 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002029
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002030- Replaced most Unicode charmap codecs with new ones using the
2031 new Unicode translate string feature in the builtin charmap
2032 codec; the codecs were created from the mapping tables available
2033 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2034 encodings now include a mapping for the Apple logo)
2035
Tim Peterse3547fd2005-12-16 23:13:57 +00002036- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002037
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002038- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002039
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002040- A new AST parser implementation was completed. The abstract
2041 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002042 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002043
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002044- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002045 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2046
Neal Norwitz708e51a2005-10-03 04:48:15 +00002047- SF Bug #976608: fix SystemError when mtime of an imported file is -1.

2053
2054- SF bug #772896: unknown encoding results in MemoryError.
2055
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002056- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002057 supported a __len__() method which evaluated to False when the iterator
2058 was empty.
2059
Guido van Rossum630db602005-09-20 18:49:54 +00002060- On 64-bit platforms, when __len__() returns a value that cannot be
2061 represented as a C int, raise OverflowError.
2062
Skip Montanarof8948ca2005-09-19 03:54:46 +00002063- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002064 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002065
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002066- SF bug #893549: parsing keyword arguments was broken with a few format
2067 codes.
2068
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002069- Changes donated by Elemental Security to make it work on AIX 5.3
2070 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2071 bug #105470: test_pwd fails on 64bit system (Opteron).
2072
Guido van Rossum539c6622005-09-14 17:49:54 +00002073- Changes donated by Elemental Security to make it work on HP-UX 11 on
2074 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2075
Georg Brandl4550b8d2005-08-26 06:43:52 +00002076- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002077 (fixes bug #1119418).
2078
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002079- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2080
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002081- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2082 exceptions that cause a function to exit.
2083
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002084- The implementation of set() and frozenset() was revised to use its
2085 own internal data structure. Memory consumption is reduced by 1/3
2086 and there are modest speed-ups as well. The API is unchanged.
2087
Tim Petersde7990b2005-07-17 23:45:23 +00002088- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2089
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002090- SF bug #1229429: PyObject_CallMethod failed to decrement some
2091 reference counts in some error exit cases.
2092
Tim Petersecc6e6a2005-07-10 22:30:55 +00002093- SF bug #1185883: Python's small-object memory allocator took over
2094 a block managed by the platform C library whenever a realloc specified
2095 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002096 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002097 portable way to copy data from the C-managed block into Python's
2098 small-object space without risking a memory fault. Python's small-object
2099 realloc now leaves such blocks under the control of the platform C
2100 realloc.
2101
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002102- SF bug #1232517: An overflow error was not detected properly when
2103 attempting to convert a large float to an int in os.utime().
2104
Raymond Hettinger3296e692005-06-29 23:29:56 +00002105- SF bug #1224347: hex longs now print with lowercase letters just
2106 like their int counterparts.
2107
Michael W. Hudson188d4362005-06-20 16:52:57 +00002108- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2109 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2110 interpreter states; back out that fix and do a better job (see
2111 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2112 for a longer write-up of the problem).
2113
Michael W. Hudsondf888462005-06-03 14:41:55 +00002114- SF patch #1180995: marshal now uses a binary format by default when
2115 serializing floats.
2116
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002117- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2118 the routines that promise to produce IEEE 754 binary representations
2119 of floats now simply copy bytes around.
2120
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002121- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2122 278.
2123
Brett Cannonc3647ac2005-04-26 03:45:26 +00002124- patch #1109424: int, long, float, complex, and unicode now check for the
2125 proper magic slot for type conversions when subclassed. Previously the
2126 magic slot was ignored during conversion. Semantics now match the way
2127 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002128 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002129 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002130 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002131
Barry Warsawc8d907c2005-04-19 23:43:40 +00002132- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2133 NULL, now raise an AttributeError when attempting to set or delete the
2134 attribute. Previously a TypeError was raised, but this was inconsistent
2135 with the equivalent pure-Python implementation.
2136
Michael W. Hudson774479c2005-04-18 08:46:17 +00002137- It is now safe to call PyGILState_Release() before
2138 PyEval_InitThreads() (note that if there is reason to believe there
2139 are multiple threads around you still must call PyEval_InitThreads()
2140 before using the Python API; this fix is for extension modules that
2141 have no way of knowing if Python is multi-threaded yet).
2142
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002143- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2144 disabled caused a crash.
2145
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002146- Bug #1165306: instancemethod_new allowed the creation of a method
2147 with im_class == im_self == NULL, which caused a crash when called.
2148
Tim Petersecc6e6a2005-07-10 22:30:55 +00002149- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002150 fixes the crash seen in bug #1165761
2151
Raymond Hettinger96229b12005-03-11 06:49:40 +00002152- Added two new builtins, any() and all().
2153
Brett Cannon409d8f22005-03-05 06:47:57 +00002154- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002155 (e.g., ``class C(): pass`` is no longer a syntax error).
2156 Patch #1176012 added support to the 'parser' module and 'compiler' package
2157 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002158
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002159- Patch #1115086: Support PY_LONGLONG in structmember.
2160
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002161- Bug #1155938: new style classes did not check that __init__() was
2162 returning None.
2163
Tim Petersecc6e6a2005-07-10 22:30:55 +00002164- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002165 ('\') with a specific error message.
2166
Martin v. Löwisff232d72005-03-03 09:24:38 +00002167- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2168
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002169- Bug #1124295: the __name__ attribute of file objects was
2170 inadvertently made inaccessible in restricted mode.
2171
Tim Petersecc6e6a2005-07-10 22:30:55 +00002172- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002173 an ferror() call.
2174
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002175- min() and max() now support key= arguments with the same meaning as in
2176 list.sort().
2177
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002178- The peephole optimizer now performs simple constant folding in expressions:
2179 (2+3) --> (5).
2180
Raymond Hettingera422c342005-01-11 03:03:27 +00002181- set and frozenset objects can now be marshalled. SF #1098985.
2182
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002183- Bug #1077106: Poor argument checking could cause memory corruption
2184 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002185
Jeremy Hyltonab630502005-02-04 18:44:06 +00002186- The parser did not complain about future statements in illegal
2187 positions. It once again reports a syntax error if a future
2188 statement occurs after anything other than a doc string.
2189
Neil Schemenauercf52c072005-08-12 17:34:58 +00002190- Change the %s format specifier for str objects so that it returns a
2191 unicode instance if the argument is not an instance of basestring and
2192 calling __str__ on the argument returns a unicode instance.
2193
Tim Petersf4e69282006-02-27 17:15:31 +00002194- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2195 current thread state when the auto-GIL-state machinery knows about
2196 it (since the thread state is being deleted, continuing to remember it
2197 can't help, but can hurt if another thread happens to get created with
2198 the same thread id).
2199
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002200Extension Modules
2201-----------------
2202

Tim Petersc9d78aa2006-03-26 23:27:58 +00002215 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002216 util, whatsound, whrandom, zmod
2217
2218- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2219
2220- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002221 is deprecated. The undocumented re.engine variable no longer exists.
2222
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002223- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2224 SS2 (single-shift 2) escape sequences correctly.
2225
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002226- The unicodedata module was updated to the 4.1 version of the Unicode
2227 database. The 3.2 version is still available as unicodedata.db_3_2_0
2228 for applications that require this specific version (such as IDNA).
2229
Neal Norwitzb62c4332006-03-04 18:35:47 +00002230- The timing module is no longer built by default. It was deprecated
2231 in PEP 4 in Python 2.0 or earlier.
2232
Guido van Rossum1968ad32006-02-25 22:38:04 +00002233- Patch 1433928: Added a new type, defaultdict, to the collections module.
2234 This uses the new __missing__ hook behavior added to dict (see above).
2235
Georg Brandldbd83392006-02-20 09:42:33 +00002236- Bug #854823: socketmodule now builds on Sun platforms even when
2237 INET_ADDRSTRLEN is not defined.
2238
Georg Brandlf4f44152006-02-18 22:29:33 +00002239- Patch #1393157: os.startfile() now has an optional argument to specify
2240 a "command verb" to invoke on the file.
2241
Neal Norwitz082b2df2006-02-07 07:04:46 +00002242- Bug #876637, prevent stack corruption when socket descriptor
2243 is larger than FD_SETSIZE.
2244
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002245- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2246 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2247 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2250 than the system default domain.
2251
Martin v. Löwis14694662006-02-03 12:54:16 +00002252- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2253 are reported, the limit on path name lengths is removed, and stat reports
2254 WindowsError now (instead of OSError).
2255
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002256- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2331 the request code argument, which results in more C-like behaviour
2332 for large or negative values.
2333
Tim Petersecc6e6a2005-07-10 22:30:55 +00002334- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002345- Bug #1166660: The readline module could segfault if hook functions
2346 were set in a different thread than that which called readline.
2347

2349
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002350- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002374- the cPickle module no longer accepts the deprecated None option in the
2375 args tuple returned by __reduce__().
2376
Raymond Hettingerb2594052004-12-05 09:25:51 +00002377- itertools.islice() now accepts None for the start and step arguments.
2378 This allows islice() to work more readily with slices:
2379 islice(s.start, s.stop, s.step)
2380

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002390- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2391 been renamed to have only a single underscore prefix. This was done to
2392 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002393
Nick Coghlan43832302006-04-23 17:04:07 +00002394- PEP 338: new module runpy defines a run_module function to support
2395 executing modules which provide access to source code or a code object
2396 via the PEP 302 import mechanisms.
2397
Anthony Baxter93f5b932006-04-03 08:05:07 +00002398- The email module's parsedate_tz function now sets the daylight savings
2399 flag to -1 (unknown) since it can't tell from the date whether it should

2406 in attribute values.
2407
Anthony Baxterc51ee692006-04-01 00:57:31 +00002408- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002409 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002410 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002411 module will not be built.
2412
Tim Petersc17976e2006-04-01 00:26:53 +00002413- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2414 aren't officially supported here, and trying to use them will probably
2415 raise an exception some day. But dicts have been allowed, and "mostly
2416 worked", so support for them won't go away without warning.
2417
Georg Brandl338ef7d2006-03-31 18:42:16 +00002418- Bug #1445068: getpass.getpass() can now be given an explicit stream
2419 argument to specify where to write the prompt.
2420
Georg Brandl22ec80b2006-03-31 18:25:44 +00002421- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2428
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002429- Queue.Queue objects now support .task_done() and .join() methods
2430 to make it easier to monitor when daemon threads have completed
2431 processing all enqueued tasks. Patch #1455676.
2432
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002433- popen2.Popen objects now preserve the command in a .cmd attribute.

2436
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002437- email 4.0 package now integrated. This is largely the same as the email 3.0
2438 package that was included in Python 2.3, except that PEP 8 module names are
2439 now used (e.g. mail.message instead of email.Message). The MIME classes
2440 have been moved to a subpackage (e.g. email.mime.text instead of
2441 email.MIMEText). The old names are still supported for now. Several
2442 deprecated Message methods have been removed and lots of bugs have been
2443 fixed. More details can be found in the email package documentation.
2444
Walter Dörwald40108c92006-03-27 08:15:44 +00002445- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2446 (a subclass of tuple) that provides incremental decoders and encoders
2447 (a way to use stateful codecs without the stream API). Python functions
2448 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2449 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2450 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002451
Walter Dörwald067db482006-03-15 22:17:27 +00002452- Patch #1359365: Calling next() on a closed StringIO.String object raises
2453 a ValueError instead of a StopIteration now (like file and cString.String do).
2454 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2455 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002456
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002457- A regrtest option -w was added to re-run failed tests in verbose mode.

2467
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002468- PEP 343: new module contextlib.py defines decorator @contextmanager
2469 and helpful context managers nested() and closing().
2470

Martin v. Löwis3e865952006-01-24 15:51:21 +00002505 specifications, raises IOErrors when proxies for unsupported protocols
2506 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002529 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2530 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2531 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2532 Ronald L. Rivest offered this advice for Python:
2533
2534 "The consensus of researchers in this area (at least as
2535 expressed at the NIST Hash Function Workshop 10/31/05),
2536 is that SHA-256 is a good choice for the time being, but
2537 that research should continue, and other alternatives may
2538 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002539
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002540- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002586- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2587 ContentTooShortException, when the actually downloaded size does not
2588 match the Content-Length header.
2589
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002590- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2591
Martin v. Löwis56066d22005-08-24 07:38:12 +00002592- Bug #1178484: Return complete lines from codec stream readers
2593 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002594 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002595
Georg Brandl6d2b3462005-08-24 07:36:17 +00002596- Bug #1192315: Disallow negative arguments to clear() in pdb.

2601 to ntpath, macpath, os2emxpath and riscospath.
2602
Guido van Rossum755149f2005-07-27 00:00:44 +00002603- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2604 __hasattr__ and __delattr__ methods on class Tk that were breaking
2605 Tkdnd.
2606
Georg Brandl5dbda752005-07-17 20:27:41 +00002607- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2608 docstrings to either "article number" or "message id".
2609
Georg Brandla4a8b822005-07-15 09:13:21 +00002610- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2611 parameter, but uses the usual "kwargs=None".
2612
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002613- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002614 Patch #1209527 (Contributed by Connelly).
2615
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002616- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2617 to W3C name (404 -> 'Not Found'). RFE #1216944.
2618
Georg Brandl9e43acf2005-07-04 17:16:07 +00002619- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2620 as this can cause problems with apps closing all file descriptors.
2621
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002622- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002623 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002624
Georg Brandl2f210b62005-06-26 22:09:06 +00002625- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2626
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002627- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2628 error messages.
2629
Georg Brandl379f99d2005-06-26 21:09:38 +00002630- Bug #1108948: Cookie.py produced invalid JavaScript code.
2631
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002632- The tokenize module now detects and reports indentation errors.
2633 Bug #1224621.
2634
Raymond Hettinger68c04532005-06-10 11:05:19 +00002635- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002636 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002637 the generate_tokens() function now accepts a callable argument that
2638 terminates by raising StopIteration.
2639
Georg Brandl9166e1a2005-06-04 09:20:03 +00002640- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2641
Georg Brandl268e61c2005-06-03 14:28:50 +00002642- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2643 component of the path.
2644
Skip Montanaro174dd222005-05-14 20:54:16 +00002645- Patch #1120353: The xmlrpclib module provides better, more transparent,
2646 support for datetime.{datetime,date,time} objects. With use_datetime set
2647 to True, applications shouldn't have to fiddle with the DateTime wrapper
2648 class at all.
2649
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002650- distutils.commands.upload was added to support uploading distribution
2651 files to PyPI.
2652
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002653- distutils.commands.register now encodes the data as UTF-8 before posting
2654 them to PyPI.
2655
Raymond Hettinger267b8682005-03-27 10:47:39 +00002656- decimal operator and comparison methods now return NotImplemented
2657 instead of raising a TypeError when interacting with other types. This
2658 allows other classes to implement __radd__ style methods and have them
2659 work as expected.
2660
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002661- Bug #1163325: Decimal infinities failed to hash. Attempting to
2662 hash a NaN raised an InvalidOperation instead of a TypeError.
2663
Tim Petersecc6e6a2005-07-10 22:30:55 +00002664- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002665 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2666

2670 to build.
2671
Martin v. Löwis637431b2005-03-03 23:12:42 +00002672- Patch #1103407: Properly deal with tarfile iterators when untarring

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002676 profile.py if available.
2677
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002678- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2679

2694
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002695- Patch #1049151: xdrlib now unpacks booleans as True or False.
2696
Raymond Hettingerbab41432005-02-05 01:31:19 +00002697- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2698
Guido van Rossumd0641422005-02-03 15:01:24 +00002699- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2700 disables recursive traversal through instance attributes, which can
2701 be exploited in various ways.
2702
Tim Peterse3547fd2005-12-16 23:13:57 +00002703- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002704 flags on the HTTP listening socket.
2705
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002706- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2707 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2708
Fred Drakefbdeaad2006-07-29 16:56:15 +00002709- Patches #893642, #1039083: add allow_none, encoding arguments to
2710 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002711
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002712- Bug #1110478: Revert os.environ.update to do putenv again.
2713
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002714- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2715
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002716- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2717
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002718- Enhancements to the csv module:
2719
2720 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002721 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002722 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002723 + Dialect parameter parsing has been re-implemented to improve error
2724 reporting.
2725 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2726 dictates.
2727 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002728 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002729 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002730 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2731 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002732 + reader now allows \r characters to be quoted (previously it only allowed
2733 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002734 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002735 + Dialect classes passed to the module are no longer instantiated by
2736 the module before being parsed (the former validation scheme required
2737 this, but the mechanism was unreliable).
2738 + The dialect registry now contains instances of the internal
2739 C-coded dialect type, rather than references to python objects.
2740 + the internal c-coded dialect type is now immutable.
2741 + register_dialect now accepts the same keyword dialect specifications
2742 as the reader and writer, allowing the user to register dialects
2743 without first creating a dialect class.
2744 + a configurable limit to the size of parsed fields has been added -
2745 previously, an unmatched quote character could result in the entire
2746 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002747 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002748 the parser field size limit (returning the former limit). The initial
2749 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002750 + A line_num attribute has been added to the reader object, which tracks
2751 the number of lines read from the source iterator. This is not
2752 the same as the number of records returned, as records can span
2753 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002754 + reader and writer objects were not being registered with the cyclic-GC.
2755 This has been fixed.
2756
Brett Cannone6539c42005-01-08 02:43:53 +00002757- _DummyThread objects in the threading module now delete self.__block that is
2758 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2759 lock primitives tend to be limited in number and thus should not be wasted on
2760 a _DummyThread object. Fixes bug #1089632.
2761
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002762- The imghdr module now detects Exif files.
2763
Raymond Hettinger6065d322004-12-20 23:51:53 +00002764- StringIO.truncate() now correctly adjusts the size attribute.
2765 (Bug #951915).
2766
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002767- locale.py now uses an updated locale alias table (built using
2768 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2769 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002770 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002771
Raymond Hettinger3557f422004-12-07 12:02:02 +00002772- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2773
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002774- the pickle module no longer accepts the deprecated None option in the
2775 args tuple returned by __reduce__().
2776
Brett Cannon84667c02004-12-07 03:25:18 +00002777- optparse now optionally imports gettext. This allows its use in setup.py.
2778
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002779- the pickle module no longer uses the deprecated bin parameter.
2780
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002781- the shelve module no longer uses the deprecated binary parameter.
2782
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002783- the pstats module no longer uses the deprecated ignore() method.
2784
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002785- the filecmp module no longer uses the deprecated use_statcache argument.
2786
Raymond Hettinger664347b2004-12-04 21:21:53 +00002787- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2788 extended or overridden by subclasses. Formerly, the subclassed method would
2789 be ignored by the rest of the module. (Bug #1078905).
2790
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002791- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002792 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002793
Walter Dörwald36733692004-12-22 12:50:50 +00002794- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2795 once when a size argument is given. This prevents a buffer overflow in the
2796 tokenizer with very long source lines.
2797
Barry Warsaw538561e2006-01-01 21:48:54 +00002798- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2799 immediately after creating the object, without any intervening
2800 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002801
Skip Montanaro05885812005-01-16 20:48:27 +00002802- The reconvert.quote function can now emit triple-quoted strings. The
2803 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002804
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002805- ``UserString.MutableString`` now supports negative indices in
2806 ``__setitem__`` and ``__delitem__``
2807
Greg Ward40407942005-03-05 02:53:17 +00002808- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2809 correctly.
2810
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002811- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2812 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2813 character even if the user has passed a size parameter to get a proper
2814 line ending. Remove the special handling of a "\r\n" that has been split
2815 between two lines.
2816
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002817- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2818 about illegal code points. The codec now supports PEP 293 style error
2819 handlers.
2820
Walter Dörwald78a78b02005-09-01 12:04:29 +00002821- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002822 from the input stream, so that the output is a byte string in the correct
2823 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002824
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002825- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2826 considering it exactly like a '*'.
2827
Walter Dörwald007f8df2005-10-09 19:42:27 +00002828- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2829 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002830
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002831- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2832
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002833- Patch #1413711: Certain patterns of differences were making difflib
2834 touch the recursion limit.
2835
Walter Dörwald58917a62006-03-31 15:26:22 +00002836- Bug #947906: An object oriented interface has been added to the calendar
2837 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002838 called as a script (e.g. via ``python -mcalendar``). Localized month and
2839 weekday names can be ouput (even if an exotic encoding is used) using

2843-----
2844
Neal Norwitz602d3392006-03-31 08:21:40 +00002845- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2846 by using -mieee gcc option.
2847
Martin v. Löwis86d66262006-02-17 08:40:11 +00002848- Patch #1432345: Make python compile on DragonFly.
2849
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002850- Build support for Win64-AMD64 was added.
2851
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002852- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2853
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002854- Patch #881820: look for openpty and forkpty also in libbsd.
2855
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002856- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2857 The zlib module is now builtin on Windows.
2858
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002859- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2860
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002861- Bug #1189330: configure did not correctly determine the necessary
2862 value of LINKCC if python was built with GCC 4.0.
2863
Trent Mick8321b422005-07-26 02:29:21 +00002864- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2865 vulnerability in zlib 1.2.1 and 1.2.2.
2866
Brett Cannon08cd5982005-04-24 22:26:38 +00002867- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2868 flags that change binary compatibility. Changes were also made to
2869 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002870 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002871
Bob Ippolitoed233462005-03-29 13:47:59 +00002872- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2873 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2874 no longer exists). This configure patch makes things right.
2875
Martin v. Löwise2713be2005-03-08 15:03:08 +00002876- Bug #1158607: Build with --disable-unicode again.
2877
Brett Cannon46d96232005-02-16 00:07:19 +00002878- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2879 defined. Discovered as a result of not being able to build on OS X.
2880
Brett Cannon516592f2004-12-07 00:42:59 +00002881- setup.py now uses the directories specified in LDFLAGS using the -L option
2882 and in CPPFLAGS using the -I option for adding library and include
2883 directories, respectively, for compiling extension modules against. This has
2884 led to the core being compiled using the values in CPPFLAGS. It also removes
2885 the need for the special-casing of both DarwinPorts and Fink for darwin since
2886 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2887 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2888 Fink, ``-I/opt/local/include`` for DarwinPorts).
2889
Brett Cannon43802422005-02-10 20:48:03 +00002890- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2891 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2892 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2893 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002895C API
2896-----
2897
Tim Petersc9d78aa2006-03-26 23:27:58 +00002898- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2899 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2900 is obtained via the ``PyObject_`` family, it must be released via the
2901 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2902 always been officially true, but when Python's small-object allocator was
2903 introduced, an attempt was made to cater to a few extension modules
2904 discovered at the time that obtained memory via ``PyObject_New`` but
2905 released it via ``PyMem_DEL``. It's years later, and if such code still
2906 exists it will fail now (probably with segfaults, but calling wrong
2907 low-level memory management functions can yield many symptoms).
2908
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002909- Added a C API for set and frozenset objects.
2910
Raymond Hettinger66517482004-12-03 11:45:13 +00002911- Removed PyRange_New().
2912
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002913- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2914 mapping argument now. This string is used as a mapping table. Byte values
2915 greater than the length of the string and 0xFFFE are treated as undefined
2916 mappings.

2921
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002922- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002923
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002924- Patch #1276356: New resource "urlfetch" is implemented. This enables
2925 even impatient people to run tests that require remote files.
