Neal Norwitz0bcafac2006-09-11 08:51:17 +0000685- Make _PyGILState_NoteThreadState() static, it was not used anywhere
686 outside of pystate.c and should not be necessary.
687
Brett Cannon19d76c52006-09-09 07:18:44 +0000688- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
689 allows calling unicode() on exceptions classes directly to succeed.

Neal Norwitz24b6f202006-09-05 04:43:56 +0000827- Fix infinite recursion when subclassing long and overriding __hash__.
828
829- Fix concatenation (+=) of long strings.
830
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000831- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000832 compared equal or unequal to a string and a UnicodeDecodeError
833 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000834
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000835 Instead, the equal (==) and unequal (!=) comparison operators will
836 now issue a UnicodeWarning and interpret the two objects as
837 unequal. The UnicodeWarning can be filtered as desired using
838 the warning framework, e.g. silenced completely, turned into an
839 exception, logged, etc.
840
841 Note that compare operators other than equal and unequal will still
842 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000843
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000844- Fix segfault when doing string formatting on subclasses of long.
845
846- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
847 with new-style classes.
848
849- Fix bug related to __len__ functions returning negative values with
850 classic classes.
851
852- Patch #1538606, Fix __index__() clipping. There were some problems
853 discovered with the API and how integers that didn't fit into Py_ssize_t
854 were handled. This patch attempts to provide enough alternatives
855 to effectively use __index__.
856
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000857- Bug #1536021: __hash__ may now return long int; the final hash
858 value is obtained by invoking hash on the long int.
859
Thomas Hellerab1049c2006-08-08 17:37:00 +0000860- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000862- Bug #1535165: fixed a segfault in input() and raw_input() when
863 sys.stdin is closed.
864
Thomas Heller74d36f02006-08-04 18:17:40 +0000865- On Windows, the PyErr_Warn function is now exported from
866 the Python dll again.
867
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000868- Bug #1191458: tracing over for loops now produces a line event
869 on each iteration. Fixing this problem required changing the .pyc
870 magic number. This means that .pyc files generated before 2.5c1
871 will be regenerated.
872
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000873- Bug #1333982: string/number constants were inappropriately stored
874 in the byte code and co_consts even if they were not used, ie
875 immediately popped off the stack.

884 generated for generator expressions.
885
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000886- The distutils version has been changed to 2.5.0. The change to
887 keep it programmatically in sync with the Python version running
888 the code (introduced in 2.5b3) has been reverted. It will continue
889 to be maintained manually as static string literal.
890
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000891- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000892 and this cannot be converted to the required C type, an exception is
893 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000894 callback returned arbitrary values to the calling code.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000896- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000897 an exception.
898
Tim Peterscbdd3502006-09-05 01:47:53 +0000899- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000900 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000901 workarounds for clocks with low resolution, to stop the code yielding
902 duplicate UUIDs.
903
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000904- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
905 before raising SystemExit, allowing IDLE to honor quit() and exit().
906
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000907- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
908
Georg Brandl7a1af772006-08-14 21:55:28 +0000909- Patch #1536071: trace.py should now find the full module name of a
910 file correctly even on Windows.
911
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000912- logging's atexit hook now runs even if the rest of the module has
913 already been cleaned up.
914
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000915- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000917- Bug #1531405, format_exception no longer raises an exception if
918 str(exception) raised an exception.
919
Neil Schemenauer06ded092006-08-04 16:20:30 +0000920- Fix a bug in the ``compiler`` package that caused invalid code to be
921 generated for nested functions.
922

932 raises the correct exceptions.
933
Thomas Heller1ce433e2006-08-14 16:20:04 +0000934- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
935 '-no-stack-protector' compiler flag for OpenBSD has been removed.
936
Thomas Heller86720042006-08-14 11:17:48 +0000937- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
938 uses the _as_parameter_ attribute when objects are passed to foreign
939 function calls. The ctypes version number was changed to 1.0.1.
940
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000941- Bug #1530559, struct.pack raises TypeError where it used to convert.
942 Passing float arguments to struct.pack when integers are expected
943 now triggers a DeprecationWarning.

970 code in OpenSSL.
971
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000972- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

978-----
979
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000980- New API for Unicode rich comparisons: PyUnicode_RichCompare()
981
Tim Peters4643c2f2006-08-10 22:45:34 +0000982- Bug #1069160. Internal correctness changes were made to
983 ``PyThreadState_SetAsyncExc()``. A test case was added, and
984 the documentation was changed to state that the return value
985 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000988What's New in Python 2.5 beta 3?
989================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000990
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000991*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000992
993Core and builtins
994-----------------
995
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000996- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000997 returned a long (see PEP 353).
998
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000999- Bug #1515471: string.replace() accepts character buffers again.
1000
Neal Norwitz07aadb12006-07-30 06:55:48 +00001001- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1002 This provides the proper warning for struct.pack().
1003 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1004
Neal Norwitz0d62a062006-07-30 06:53:31 +00001005- Patch #1531113: Fix augmented assignment with yield expressions.
1006 Also fix a SystemError when trying to assign to yield expressions.
1007
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001008- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1009 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1010 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1011 excessive filesystem operations during imports.
1012
Tim Petersbc24eee2006-07-27 01:14:53 +00001013- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1014 operations on signed longs that are formally undefined by C.
1015 Unfortunately, at least one compiler now cares about that, so complicated
1016 the code to make that compiler happy again.
1017
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001018- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1019
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001020- Patch #1232023: Stop including current directory in search
1021 path on Windows.
1022
Neal Norwitze1fdb322006-07-21 05:32:28 +00001023- Fix some potential crashes found with failmalloc.
1024
Neal Norwitze7563102006-07-17 01:00:16 +00001025- Fix warnings reported by Klocwork's static analysis tool.
1026
Neal Norwitz84be93b2006-07-16 01:50:38 +00001027- Bug #1512814, Fix incorrect lineno's when code within a function
1028 had more than 255 blank lines.
1029
Georg Brandl9dceedb2006-07-12 15:31:17 +00001030- Patch #1521179: Python now accepts the standard options ``--help`` and
1031 ``--version`` as well as ``/?`` on Windows.
1032
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001033- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001034 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001035 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001036
Tim Peters112aad32006-07-19 00:03:19 +00001037- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001038 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001039 new ``sys._current_frames()`` returns a dictionary with one entry,
1040 mapping the faux "thread id" 0 to the current frame.
1041
Ronald Oussoren3075e162006-07-25 20:28:55 +00001042- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001043
Ronald Oussoren3075e162006-07-25 20:28:55 +00001044
Neal Norwitza1f10902006-07-12 07:28:29 +00001045Library
1046-------
1047
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001048- Correction of patch #1455898: In the mbcs decoder, set final=False
1049 for stream decoder, but final=True for the decode function.
1050
Georg Brandl07fec3a2006-08-01 18:49:24 +00001051- os.urandom no longer masks unrelated exceptions like SystemExit or
1052 KeyboardInterrupt.
1053
Tim Peters4643c2f2006-08-10 22:45:34 +00001054- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001055 shutil.copytree on Windows
1056
Georg Brandle34ac7c2006-07-30 11:07:23 +00001057- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1058 refers to file descriptors, not file objects.
1059
Tim Peterscbdd3502006-09-05 01:47:53 +00001060- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001061 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001062 #1513611, and probably others.
1063
Georg Brandledd9b0d2006-07-29 09:33:26 +00001064- Bug #1441397: The compiler module now recognizes module and function
1065 docstrings correctly as it did in Python 2.4.
1066
Tim Peters6f681472006-07-27 23:44:37 +00001067- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1068 lost that tests are sorted by name before being run. This rarely
1069 matters for well-written tests, but can create baffling symptoms if
1070 side effects from one test to the next affect outcomes. ``DocTestFinder``
1071 has been changed to sort the list of tests it returns.
1072
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001073- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001074 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001075
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001076- Bug #978833: Really close underlying socket in _socketobject.close.
1077
Georg Brandldb232dc2006-08-20 13:15:43 +00001078- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1079 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001080
Georg Brandlcf0c1722006-07-26 07:23:32 +00001081- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1082 to recursive calls and call it with the failing package name.
1083
Martin v. Löwis0b483032006-07-25 09:53:12 +00001084- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1085
Georg Brandlc13c34c2006-07-24 14:09:56 +00001086- Patch #1515343: Fix printing of deprecated string exceptions with a
1087 value in the traceback module.
1088
Greg Ward48fae7a2006-07-23 16:05:51 +00001089- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1090
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001091- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1092
Brett Cannoncaebe222006-07-18 04:41:36 +00001093- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1094 argument tuple. For arguments where zero is illegal, the value is forced to
1095 the minimum value that is correct. This is to support an undocumented but
1096 common way people used to fill in inconsequential information in the time
1097 tuple pre-2.4.
1098
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001099- Patch #1220874: Update the binhex module for Mach-O.
1100
Barry Warsawb110bad2006-07-21 14:51:07 +00001101- The email package has improved RFC 2231 support, specifically for
1102 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1103 (name*0=<blah>) parameter continuations. This may change the types of
1104 values returned from email.message.Message.get_param() and friends.
1105 Specifically in some cases where non-encoded continuations were used,
1106 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1107 will just return the string (since non-encoded continuations don't have
1108 charset and language parts).
1109
1110 Also, whereas % values were decoded in all parameter continuations, they are
1111 now only decoded in encoded parameter parts.
1112
Ronald Oussoren3075e162006-07-25 20:28:55 +00001113- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1114
1115- Bug #1517996: IDLE now longer shows the default Tk menu when a
1116 path browser, class browser or debugger is the frontmost window on MacOS X
1117
Barry Warsaw00decd72006-07-27 23:43:15 +00001118- Patch #1520294: Support for getset and member descriptors in types.py,
1119 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1120 of an object against these built-in types and more importantly, for getting
1121 their docstrings printed in the interactive interpreter's help() function.
1122

1126
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001127- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1128 a socket operation on a socket with a timeout, the exception will be
1129 caught correctly. Previously, the exception was not caught.
1130
Thomas Heller1393d6a2006-07-28 21:43:20 +00001131- Patch #1529514: The _ctypes extension is now compiled on more
1132 openbsd target platforms.
1133
Tim Peters9cab5932006-07-28 00:30:00 +00001134- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1135 a memory leak, affecting pickles and deep copies.
1136
Tim Petersbc24eee2006-07-27 01:14:53 +00001137- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001138 Paul Eggert.
1139
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001140- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1141
Thomas Hellerce049a02006-07-14 17:51:14 +00001142- Patch #1521817: Index range checking on ctypes arrays containing
1143 exactly one element enabled again. This allows iterating over these
1144 arrays, without the need to check the array size before.
1145
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001146- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001147 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001148 /dev/null in certain cases; this is now fixed.
1149
Thomas Heller47d7a062006-07-12 08:43:47 +00001150- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1151 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001152
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001153- Because of a misspelled preprocessor symbol, ctypes was always
1154 compiled without thread support; this is now fixed.
1155
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001156- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1157 methods now allow their database parameter to be None as the
1158 sleepycat API allows.
1159
Matt Flemingec926502006-07-28 11:27:27 +00001160- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1161 bluetooth API compared with Linux and FreeBSD.
1162
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001163Tests
1164-----
1165
1166- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1167 how long the test file should take to play. Now accepts taking 2.93 secs
1168 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1169
Georg Brandl4793aa32006-07-28 18:31:39 +00001170- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1171 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1172 run via ``regrtest.py``. Now they do.

1181
1182- PythonLauncher now works correctly when the path to the script contains
1183 characters that are treated specially by the shell (such as quotes).
1184
1185- Bug #1527397: PythonLauncher now launches scripts with the working directory
1186 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001187 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001188 expect.

1196Core and builtins
1197-----------------
1198
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001199- Bug #1441486: The literal representation of -(sys.maxint - 1)
1200 again evaluates to a int object, not a long.
1201
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001202- Bug #1501934: The scope of global variables that are locally assigned
1203 using augmented assignment is now correctly determined.
1204
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001205- Bug #927248: Recursive method-wrapper objects can now safely
1206 be released.
1207
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001208- Bug #1417699: Reject locale-specific decimal point in float()
1209 and atof().
1210
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001211- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1212 omit a default "error" argument for NULL pointer. This allows
1213 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001214
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001215- Bug #1519018: 'as' is now validated properly in import statements.
1216
Neal Norwitz28746ab2006-07-09 22:14:42 +00001217- On 64 bit systems, int literals that use less than 64 bits are
1218 now ints rather than longs.
1219
Neal Norwitzed657552006-07-10 00:04:44 +00001220- Bug #1512814, Fix incorrect lineno's when code at module scope
1221 started after line 256.
1222
Tim Peters32a83612006-07-10 21:08:24 +00001223- New function ``sys._current_frames()`` returns a dict mapping thread
1224 id to topmost thread stack frame. This is for expert use, and is
1225 especially useful for debugging application deadlocks. The functionality
1226 was previously available in Fazal Majid's ``threadframe`` extension
1227 module, but it wasn't possible to do this in a wholly threadsafe way from
1228 an extension.
1229

1232
Martin v. Löwis77621582006-07-30 13:27:31 +00001233- Bug #1257728: Mention Cygwin in distutils error message about a missing
1234 VS 2003.
1235
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001236- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1237
Tim Peters32a83612006-07-10 21:08:24 +00001238- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001239 environment variable to be set in order to the SDK environment
1240 for finding the compiler, include files, etc.
1241
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001242- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1243
Nick Coghlan2d792252006-07-06 13:47:18 +00001244- warnings.py now ignores ImportWarning by default
1245
Thomas Woutersadd19112006-07-05 11:03:49 +00001246- string.Template() now correctly handles tuple-values. Previously,
1247 multi-value tuples would raise an exception and single-value tuples would
1248 be treated as the value they contain, instead.
1249
Martin v. Löwisede77f52006-07-03 13:01:35 +00001250- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1251 even if some data are received.
1252
Martin v. Löwis45482392006-07-03 12:28:58 +00001253- Bug #1267547: Put proper recursive setup.py call into the
1254 spec file generated by bdist_rpm.
1255
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001256- Bug #1514693: Update turtle's heading when switching between
1257 degrees and radians.
1258
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001259- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001260 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001261
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001262- Bug #1514703: Only setup canvas window in turtle when the canvas
1263 is created.
1264
Martin v. Löwis7596e832006-07-01 15:33:37 +00001265- Bug #1513223: .close() of a _socketobj now releases the underlying

1269 attribute values.
1270
1271- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1272 sgmllib ('[' and ']' were not accepted).
1273
Georg Brandl1be63af2006-06-28 20:23:25 +00001274- Fix a bug in the turtle module's end_fill function.
1275
Brett Cannon53ab5b72006-06-22 16:49:14 +00001276- Bug #1510580: The 'warnings' module improperly required that a Warning
1277 category be either a types.ClassType and a subclass of Warning. The proper
1278 check is just that it is a subclass with Warning as the documentation states.
1279
Georg Brandlad29e632006-06-21 17:45:17 +00001280- The compiler module now correctly compiles the new try-except-finally
1281 statement (bug #1509132).
1282
Neal Norwitz60373cd2006-06-22 06:30:50 +00001283- The wsgiref package is now installed properly on Unix.
1284
Vinay Sajip28e57612006-07-01 10:45:20 +00001285- A bug was fixed in logging.config.fileConfig() which caused a crash on
1286 shutdown when fileConfig() was called multiple times.
1287
Gerhard Häring762fbd32006-07-02 17:48:30 +00001288- The sqlite3 module did cut off data from the SQLite database at the first
1289 null character before sending it to a custom converter. This has been fixed
1290 now.
1291
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001292Extension Modules
1293-----------------
1294
Tim Peters112aad32006-07-19 00:03:19 +00001295- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1296 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1297 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001298
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001299- Assigning None to pointer type fields in ctypes structures possible
1300 overwrote the wrong fields, this is fixed now.
1301
1302- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1303 on non-Windows platforms.
1304
1305- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1306 integer or long, without range checking.
1307
1308- Patch #1517790: It is now possible to use custom objects in the ctypes
1309 foreign function argtypes sequence as long as they provide a from_param
1310 method, no longer is it required that the object is a ctypes type.
1311
1312- The '_ctypes' extension module now works when Python is configured
1313 with the --without-threads option.
1314
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001315- Bug #1513646: os.access on Windows now correctly determines write
1316 access, again.
1317
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001318- Bug #1512695: cPickle.loads could crash if it was interrupted with
1319 a KeyboardInterrupt.
1320
Neal Norwitza12aa882006-07-06 06:45:08 +00001321- Bug #1296433: parsing XML with a non-default encoding and
1322 a CharacterDataHandler could crash the interpreter in pyexpat.
1323
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001324- Patch #1516912: improve Modules support for OpenVMS.
1325
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001326Build

1328
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001329- Automate Windows build process for the Win64 SSL module.
1330
Tim Peters32a83612006-07-10 21:08:24 +00001331- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001332 Previously, the slight difference could cause compilation errors of the
1333 'zlib' module on systems with more than one version of zlib.
1334
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001335- The MSI compileall step was fixed to also support a TARGETDIR
1336 with spaces in it.
1337
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001338- Bug #1517388: sqlite3.dll is now installed on Windows independent
1339 of Tcl/Tk.
1340
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001341- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001342 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001343
Neal Norwitzb15ac312006-06-29 04:10:08 +00001344Tests
1345-----
1346
1347- Call os.waitpid() at the end of tests that spawn child processes in order
1348 to minimize resources (zombies).
1349
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001350Documentation
1351-------------
1352
Nick Coghlan2d792252006-07-06 13:47:18 +00001353- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1354 documentation for the warnings module.
1355
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001356- Patch #1509163: MS Toolkit Compiler no longer available.
1357
Neal Norwitz56640df2006-07-10 02:36:41 +00001358- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001361What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001362================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001363
Anthony Baxterd1136802006-06-19 12:04:15 +00001364*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001365
1366Core and builtins
1367-----------------
1368
Georg Brandla56b9152006-06-19 06:35:54 +00001369- Patch #1507676: Error messages returned by invalid abstract object operations
1370 (such as iterating over an integer) have been improved and now include the
1371 type of the offending object to help with debugging.
1372
Brett Cannonea3912b2006-06-13 21:46:41 +00001373- Bug #992017: A classic class that defined a __coerce__() method that returned
1374 its arguments swapped would infinitely recurse and segfault the interpreter.
1375
Neal Norwitz909eb122006-06-12 02:13:21 +00001376- Fix the socket tests so they can be run concurrently.
1377
Neal Norwitzb9845e72006-06-12 02:11:18 +00001378- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001379 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001380
Brett Cannon22565aa2006-06-09 22:31:23 +00001381- Bug #532646: object.__call__() will continue looking for the __call__
1382 attribute on objects until one without one is found. This leads to recursion
1383 when you take a class and set its __call__ attribute to an instance of the
1384 class. Originally fixed for classic classes, but this fix is for new-style.
1385 Removes the infinite_rec_3 crasher.
1386
Georg Brandl24250812006-06-09 18:45:48 +00001387- The string and unicode methods startswith() and endswith() now accept
1388 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1389
Brett Cannonde3b0522006-06-08 17:00:45 +00001390- Buffer objects, at the C level, never used the char buffer
1391 implementation even when the char buffer for the wrapped object was
1392 explicitly requested (originally returned the read or write buffer).
1393 Now a TypeError is raised if the char buffer is not present but is
1394 requested.
1395
Georg Brandlddbaa662006-06-04 21:56:52 +00001396- Patch #1346214: Statements like "if 0: suite" are now again optimized
1397 away like they were in Python 2.4.
1398
Georg Brandlb7c8f542006-05-27 12:30:25 +00001399- Builtin exceptions are now full-blown new-style classes instead of
1400 instances pretending to be classes, which speeds up exception handling
1401 by about 80% in comparison to 2.5a2.
1402
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001403- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1404 Unicode 4.1.
1405
Georg Brandlf4ef1162006-05-26 18:03:31 +00001406- Patch #921466: sys.path_importer_cache is now used to cache valid and
1407 invalid file paths for the built-in import machinery which leads to
1408 fewer open calls on startup.
1409
Tim Peters696cf432006-05-24 21:10:40 +00001410- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1411 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1412 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1413 the number of input digits (it was and remains linear-time for bases
1414 2, 4, 8, 16 and 32).
1415
Tim Petersb713ec22006-05-23 18:45:30 +00001416- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1417 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1418 an integer close to ``sys.maxint``. This was repaired by patch
1419 #1335972, which also gives a nice speedup.
1420
Richard Jonescebbefc2006-05-23 18:28:17 +00001421- Patch #1337051: reduced size of frame objects.
1422
1423- PyErr_NewException now accepts a tuple of base classes as its
1424 "base" parameter.
1425
Richard Jones7c88dcc2006-05-23 10:37:38 +00001426- Patch #876206: function call speedup by retaining allocated frame
1427 objects.
1428
Georg Brandl7b90e162006-05-18 07:01:27 +00001429- Bug #1462152: file() now checks more thoroughly for invalid mode
1430 strings and removes a possible "U" before passing the mode to the
1431 C library function.
1432
Neal Norwitz1004a532006-05-15 07:17:23 +00001433- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1434
Neal Norwitz373f0a72006-05-15 07:04:36 +00001435- Bug #1487966: Fix SystemError with conditional expression in assignment
1436
Martin v. Löwis879768d2006-05-11 13:28:43 +00001437- WindowsError now has two error code attributes: errno, which carries
1438 the error values from errno.h, and winerror, which carries the error
1439 values from winerror.h. Previous versions put the winerror.h values
1440 (from GetLastError()) into the errno attribute.
1441
Martin v. Löwis77736712006-05-04 05:51:03 +00001442- Patch #1475845: Raise IndentationError for unexpected indent.
1443
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001444- Patch #1479181: split open() and file() from being aliases for each other.
1445
Tim Peters44bd9862006-06-01 13:49:23 +00001446- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1447 methods were always silently ignored by dictionaries when comparing keys.
1448 They are now passed through (except when using the C API function
1449 ``PyDict_GetItem()``, whose semantics did not change).
1450
1451- Bug #1456209: In some obscure cases it was possible for a class with a
1452 custom ``__eq__()`` method to confuse dict internals when class instances
1453 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1454 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00001459- Bug #1295808: expat symbols should be namespaced in pyexpat
1460
1461- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1462
Brett Cannon6ee7d012006-06-08 16:23:04 +00001463- Change binascii.hexlify to accept a read-only buffer instead of only a char
1464 buffer and actually follow its documentation.
1465
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001466- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1467
Nick Coghlanc649ec52006-05-29 12:43:05 +00001468- Patch #1478788 (modified version): The functional extension module has
1469 been renamed to _functools and a functools Python wrapper module added.
1470 This provides a home for additional function related utilities that are
1471 not specifically about functional programming. See PEP 309.
1472
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001473- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001477- Patch #1435422: zlib's compress and decompress objects now have a
1478 copy() method.
1479
Andrew MacIntyre92913322006-06-13 15:04:24 +00001480- Patch #1454481: thread stack size is now tunable at runtime for thread
1481 enabled builds on Windows and systems with Posix threads support.
1482
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001483- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1484 (up to the system limit of 32K characters).
1485
1486- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1487 As a result, these functions now raise WindowsError instead of OSError.
1488
Tim Peters7a822da2006-05-25 21:50:17 +00001489- ``time.clock()`` on Win64 should use the high-performance Windows
1490 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1491 Windows platforms).
1492
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001493- Calling Tk_Init twice is refused if the first call failed as that
1494 may deadlock.
1495
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001496- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1497 accept it without potentially using an uninitialized pointer.
1498
1499- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1500 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1501 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001502
Gregory P. Smith372b5832006-06-05 18:48:21 +00001503- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001504 [pybsddb project SF patch number 1466734]
1505
Gregory P. Smith372b5832006-06-05 18:48:21 +00001506- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1507 parameter is supplied. [SF pybsddb bug #1477863]
1508
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001509- bsddb: the __len__ method of a DB object has been fixed to return correct
1510 results. It could previously incorrectly return 0 in some cases.
1511 Fixes SF bug 1493322 (pybsddb bug 1184012).
1512
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001513- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1514 aborts the db transaction safely when a modifier callback fails.
1515 Fixes SF python patch/bug #1408584.
1516
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001517- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001518 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001519 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1520 database calls that would previously deadlock. [SF python bug #775414]
1521
Vinay Sajip28e57612006-07-01 10:45:20 +00001522- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1544 mime.types file for determining MIME types.
1545
Georg Brandl2605ca82006-06-14 06:08:31 +00001546- Bug #1339007: Shelf objects now don't raise an exception in their
1547 __del__ method when initialization failed.
1548
Martin v. Löwisd8251432006-06-14 05:21:04 +00001549- Patch #1455898: The MBCS codec now supports the incremental mode for
1550 double-byte encodings.
1551
Tim Peters43898b42006-06-14 04:09:25 +00001552- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1553 guarantee that adjacent triples in the return list always describe
1554 non-adjacent blocks. Previously, a pair of matching blocks could end
1555 up being described by multiple adjacent triples that formed a partition
1556 of the matching pair.
1557
Greg Ward0e0c9f42006-06-11 16:24:11 +00001558- Bug #1498146: fix optparse to handle Unicode strings in option help,
1559 description, and epilog.
1560

1564 clarify docs.
1565
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001566- The wsgiref package has been added to the standard library.
1567
Nick Coghlan676725d2006-06-08 13:54:49 +00001568- The functions update_wrapper() and wraps() have been added to the functools
1569 module. These make it easier to copy relevant metadata from the original
1570 function when writing wrapper functions.
1571
Tim Petersd6a9eef2006-06-05 01:48:21 +00001572- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1573 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001574
Martin v. Löwis3f767792006-06-04 19:36:28 +00001575- Patch #1359618: Speed up charmap encoder by using a trie structure
1576 for lookup.
1577
Tim Petersd609b1a2006-06-02 23:22:51 +00001578- The functions in the ``pprint`` module now sort dictionaries by key
1579 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1580 if and only if its display required more than one line, although that
1581 wasn't documented. The new behavior increases predictability; e.g.,
1582 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1583
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001584- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1586
Georg Brandl2b330372006-05-28 20:23:12 +00001587- Patch #1496206: improve urllib2 handling of passwords with respect to
1588 default HTTP and HTTPS ports.
1589
George Yoshidaf3c65de2006-05-28 16:39:09 +00001590- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1591
Bob Ippolito7298f272006-05-23 18:43:47 +00001592- Patch #1281707: speed up gzip.readline.
1593
Georg Brandlb89316f2006-05-17 15:51:16 +00001594- Patch #1180296: Two new functions were added to the locale module:
1595 format_string() to get the effect of "format % items" but locale-aware,
1596 and currency() to format a monetary number with currency sign.
1597
Georg Brandle3a25832006-05-17 14:56:04 +00001598- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1599 and several features added, such as speed and geometry control.
1600
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001601- Patch #1488881: add support for external file objects in bz2 compressed
1602 tarfiles.
1603
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001604- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1605 stdout arguments, making it possible to redirect input and output
1606 for remote debugging.
1607
1608- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1609 a couple of issues, notably handling of long file names using the
1610 GNU LONGNAME extension.
1611
1612- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1613 new flag when ``name`` is already the name of an option flag.
1614
1615- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1616 package.
1617
1618- Patch #1472854: make the rlcompleter.Completer class usable on non-
1619 UNIX platforms.

1659Core and builtins
1660-----------------
1661
Thomas Heller1b046642006-04-18 18:51:06 +00001662- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1663 by converting these apis from macros into exported functions again:
1664
1665 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1666 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1667 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1668 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1669 PyRun_String Py_CompileString
1670
Martin v. Löwis45294a92006-04-18 06:24:08 +00001671- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1672
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001673- All uses of PyStructSequence_InitType have been changed to initialize
1674 the type objects only once, even if the interpreter is initialized
1675 multiple times.
1676
Neal Norwitz61546162006-04-14 05:20:28 +00001677- Bug #1454485, array.array('u') could crash the interpreter. This was
1678 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1679 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1680
1681- Py_UNICODE is unsigned. It was always documented as unsigned, but
1682 due to a bug had a signed value in previous versions.
1683
Tim Peters3a5e8b12006-04-11 01:44:07 +00001684- Patch #837242: ``id()`` of any Python object always gives a positive
1685 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1686 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001687 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001688 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001689
Tim Peters3a5e8b12006-04-11 01:44:07 +00001690 def __hash__(self):
1691 return id(self) # WRONG
1692
1693 because a hash result must be a (short) Python int but it was always
1694 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001695 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001696 was always usable as a hash value before this patch. That's no longer
1697 necessarily so.
1698
1699- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001700 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001701 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001702 #1454844)
1703
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001704- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1705 involving generators that have paused outside of any ``try`` or ``with``
1706 blocks. (In 2.5a1, a paused generator that was part of a reference
1707 cycle could not be garbage collected, regardless of whether it was
1708 paused in a ``try`` or ``with`` block.)

1722 the cachesize parameter.
1723
1724- Bug #1149413: bsddb.*open() no longer raises an exception when using
1725 a temporary db (file=None) with the 'n' flag to truncate on open.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001736- Bug #1223937: subprocess.CalledProcessError reports the exit status
1737 of the process using the returncode attribute, instead of
1738 abusing errno.
1739
Tim Peters711bf302006-04-25 03:31:36 +00001740- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1741 a doctest to be skipped (the code is not run, and the expected output
1742 or exception is ignored).
1743
Nick Coghlanda2268f2006-04-24 04:37:15 +00001744- Fixed contextlib.nested to cope with exceptions being raised and
1745 caught inside exit handlers.
1746
Greg Wardab05edc2006-04-23 03:47:58 +00001747- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1748 hex, octal, or binary; add ``append_const`` action; keep going if
1749 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1750 added ``epilog`` for better help generation).
1751
Tim Peters21fbd572006-04-21 21:18:10 +00001752- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1753 called from a thread spawned as a side effect of importing a module.
1754
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001755- The pydoc module now supports documenting packages contained in
1756 .zip or .egg files.
1757
1758- The pkgutil module now has several new utility functions, such
1759 as ``walk_packages()`` to support working with packages that are either
1760 in the filesystem or zip files.
1761
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001762- The mailbox module can now modify and delete messages from
1763 mailboxes, in addition to simply reading them. Thanks to Gregory
1764 K. Johnson for writing the code, and to the 2005 Google Summer of
1765 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001766
Tim Petersc7605f22006-04-17 21:12:33 +00001767- The ``__del__`` method of class ``local`` in module ``_threading_local``
1768 returned before accomplishing any of its intended cleanup.
1769
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001770- Patch #790710: Add breakpoint command lists in pdb.
1771
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001772- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1775
Anthony Baxtere29002c2006-04-12 12:07:31 +00001776- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1777 Windows. Bug #1469163.
1778

1789
Skip Montanaro262fb922006-04-21 02:31:07 +00001790- The pstats.Stats class accepts an optional stream keyword argument to
1791 direct output to an alternate file-like object.
1792
Anthony Baxter51bcb682006-04-05 14:51:42 +00001793Build
1794-----
1795
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001796- The Makefile now has a reindent target, which runs reindent.py on
1797 the library.
1798
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001799- Patch #1470875: Building Python with MS Free Compiler
1800
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001801- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001802
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001803- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1804 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001805 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001806 CXX from --with-cxx-main, see description in README.
1807
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001808- Patch #1429775: Link extension modules with the shared libpython.
1809
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001810- Fixed a libffi build problem on MIPS systems.
1811
Tim Peters8931ff12006-05-13 23:28:20 +00001812- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1813 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1814 and "%zu" for unsigned integers of type ``size_t``.
1815
Anthony Baxter51bcb682006-04-05 14:51:42 +00001816Tests
1817-----
1818
Nick Coghlanda2268f2006-04-24 04:37:15 +00001819- test_contextlib now checks contextlib.nested can cope with exceptions
1820 being raised and caught inside exit handlers.
1821
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001822- test_cmd_line now checks operation of the -m and -c command switches
1823
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001824- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1825 it separately and by hand. It also wasn't cleaning up its changes to
1826 the current Decimal context.
1827
Thomas Woutersabd08882006-04-26 15:53:30 +00001828- regrtest.py now has a -M option to run tests that test the new limits of
1829 containers, on 64-bit architectures. Running these tests is only sensible
1830 on 64-bit machines with more than two gigabytes of memory. The argument
1831 passed is the maximum amount of memory for the tests to use.
1832
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001833Tools
1834-----

Anthony Baxter51bcb682006-04-05 14:51:42 +00001839Documentation
1840-------------
1841
Tim Petersb06d28c2006-05-12 01:57:59 +00001842- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1843
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001844- PEP 343: Added Context Types section to the library reference
1845 and attempted to bring other PEP 343 related documentation into
1846 line with the implementation and/or python-dev discussions.
1847
Tim Peters8dc73d22006-04-24 02:03:16 +00001848- Bug #1337990: clarified that ``doctest`` does not support examples
1849 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001850

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001852What's New in Python 2.5 alpha 1?
1853=================================
1854
Anthony Baxterebed3f62006-04-03 15:03:44 +00001855*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001856
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001857Core and builtins
1858-----------------
1859
Nick Coghlan43832302006-04-23 17:04:07 +00001860- PEP 338: -m command line switch now delegates to runpy.run_module
1861 allowing it to support modules in packages and zipfiles
1862
Martin v. Löwisc661b882006-04-20 04:54:23 +00001863- On Windows, .DLL is not an accepted file name extension for
1864 extension modules anymore; extensions are only found if they
1865 end in .PYD.
1866
Martin v. Löwisea62d252006-04-03 10:56:49 +00001867- Bug #1421664: sys.stderr.encoding is now set to the same value as
1868 sys.stdout.encoding.
1869
Neal Norwitz92e212f2006-04-03 04:48:37 +00001870- __import__ accepts keyword arguments.
1871
Georg Brandlccadf842006-03-31 18:54:53 +00001872- Patch #1460496: round() now accepts keyword arguments.
1873
Anthony Baxter262c00a2006-03-30 10:53:17 +00001874- Fixed bug #1459029 - unicode reprs were double-escaped.
1875
Hye-Shik Changd478f342006-03-23 12:32:36 +00001876- Patch #1396919: The system scope threads are reenabled on FreeBSD
1877 5.4 and later versions.
1878
Neal Norwitze98ccf62006-03-23 05:39:47 +00001879- Bug #1115379: Compiling a Unicode string with an encoding declaration
1880 now gives a SyntaxError.
1881
Georg Brandlabd1ff82006-03-18 07:59:59 +00001882- Previously, Python code had no easy way to access the contents of a
1883 cell object. Now, a ``cell_contents`` attribute has been added
1884 (closes patch #1170323).
1885
Tim Peterscf79aac2006-03-16 01:14:46 +00001886- Patch #1123430: Python's small-object allocator now returns an arena to
1887 the system ``free()`` when all memory within an arena becomes unused
1888 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1889 freed. Some applications will see a drop in virtual memory size now,
1890 especially long-running applications that, from time to time, temporarily
1891 use a large number of small objects. Note that when Python returns an
1892 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001893 platform C library will in turn return that memory to the operating system.
1894 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001895 appears to be effective at least on Microsoft C and gcc-based systems.
1896 Thanks to Evan Jones for hard work and patience.
1897
Georg Brandl533ff6f2006-03-08 18:09:27 +00001898- Patch #1434038: property() now uses the getter's docstring if there is
1899 no "doc" argument given. This makes it possible to legitimately use
1900 property() as a decorator to produce a read-only property.
1901
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001902- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1903 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1904 of requiring an int or long in slicing and a few other contexts, enabling
1905 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1906
Neal Norwitz995acdf2006-03-07 05:01:00 +00001907- Fixed various bugs reported by Coverity's Prevent tool.
1908
Brett Cannonbf364092006-03-01 04:25:17 +00001909- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1910 new exception base class, BaseException, which has a new message attribute.
1911 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1912 Raising a string exception now raises a DeprecationWarning.
1913
Thomas Woutersfb609f42006-02-28 16:37:25 +00001914- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1915 explicitly relative, using 'from .module import name' to mean 'from the same
1916 package as this module is in. Imports without dots still default to the
1917 old relative-then-absolute, unless 'from __future__ import
1918 absolute_import' is used.
1919
Brett Cannona7446e32006-02-27 23:39:10 +00001920- Properly check if 'warnings' raises an exception (usually when a filter set
1921 to "error" is triggered) when raising a warning for raising string
1922 exceptions.
1923
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001924- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001925 The name was removed from Include/code.h.
1926
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001927- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001928
Guido van Rossum1968ad32006-02-25 22:38:04 +00001929- Patch 1433928:
1930 - The copy module now "copies" function objects (as atomic objects).
1931 - dict.__getitem__ now looks for a __missing__ hook before raising
1932 KeyError.
1933
Tim Peters84ef21c2006-02-28 20:39:06 +00001934- PEP 343: with statement implemented. Needs ``from __future__ import
1935 with_statement``. Use of 'with' as a variable will generate a warning.
1936 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001937 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001938 The following objects have __context__ methods:
1939 - The built-in file type.
1940 - The thread.LockType type.
1941 - The following types defined by the threading module:
1942 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1943 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001944
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001945- Fix the encodings package codec search function to only search
1946 inside its own package. Fixes problem reported in patch #1433198.
1947
1948 Note: Codec packages should implement and register their own
1949 codec search function. PEP 100 has the details.
1950
Tim Peters9ea89d22006-06-04 03:26:02 +00001951- PEP 353: Using ``Py_ssize_t`` as the index type.
1952
1953- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1954 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1955 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1956 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1957 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001958
Neal Norwitzfc76d632006-01-10 06:03:13 +00001959- Patch #1400181, fix unicode string formatting to not use the locale.
1960 This is how string objects work. u'%f' could use , instead of .
1961 for the decimal point. Now both strings and unicode always use periods.
1962
Neal Norwitz671b9e32006-01-09 07:07:12 +00001963- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1964 configure would break checking curses.h.
1965
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001966- Bug #959576: The pwd module is now builtin. This allows Python to be
1967 built on UNIX platforms without $HOME set.
1968
Neal Norwitzc10978f2005-12-19 06:07:16 +00001969- Bug #1072182, fix some potential problems if characters are signed.
1970
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001971- Bug #889500, fix line number on SyntaxWarning for global declarations.
1972
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001973- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1974
Neal Norwitze7214a12005-12-18 05:03:17 +00001975- Support for converting hex strings to floats no longer works.
1976 This was not portable. float('0x3') now raises a ValueError.
1977
Barry Warsaw2a38a862005-12-18 01:27:35 +00001978- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001979 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001980 is now displayed in interactive prompt banner.
1981
Georg Brandlfa166682005-12-17 21:45:17 +00001982- Implementation of PEP 341 - Unification of try/except and try/finally.
1983 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001984 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001985
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001986- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1987 now encodes backslash correctly.
1988
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001989- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1990
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001991- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001992 and long longs.
1993
Neal Norwitz67715f02005-11-09 06:59:35 +00001994- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001995 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001996 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001997
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001998- Replaced most Unicode charmap codecs with new ones using the
1999 new Unicode translate string feature in the builtin charmap
2000 codec; the codecs were created from the mapping tables available
2001 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2002 encodings now include a mapping for the Apple logo)
2003
Tim Peterse3547fd2005-12-16 23:13:57 +00002004- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002005
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002006- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002007
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002008- A new AST parser implementation was completed. The abstract
2009 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002010 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002011
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002012- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002013 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2014
Neal Norwitz708e51a2005-10-03 04:48:15 +00002015- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2016
Neal Norwitz11bd1192005-10-03 00:54:56 +00002017- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2018 Provide a warning when a directory is passed on the command line.
2019
Neal Norwitz40d37812005-10-02 01:48:49 +00002020- Fix segfault with invalid coding.
2021
2022- SF bug #772896: unknown encoding results in MemoryError.
2023
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002024- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002025 supported a __len__() method which evaluated to False when the iterator
2026 was empty.
2027
Guido van Rossum630db602005-09-20 18:49:54 +00002028- On 64-bit platforms, when __len__() returns a value that cannot be
2029 represented as a C int, raise OverflowError.
2030
Skip Montanarof8948ca2005-09-19 03:54:46 +00002031- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002032 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002033
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002034- SF bug #893549: parsing keyword arguments was broken with a few format
2035 codes.
2036
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002037- Changes donated by Elemental Security to make it work on AIX 5.3
2038 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2039 bug #105470: test_pwd fails on 64bit system (Opteron).
2040
Guido van Rossum539c6622005-09-14 17:49:54 +00002041- Changes donated by Elemental Security to make it work on HP-UX 11 on
2042 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2043
Georg Brandl4550b8d2005-08-26 06:43:52 +00002044- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002045 (fixes bug #1119418).
2046
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002047- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2048
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002049- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2050 exceptions that cause a function to exit.
2051
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002052- The implementation of set() and frozenset() was revised to use its
2053 own internal data structure. Memory consumption is reduced by 1/3
2054 and there are modest speed-ups as well. The API is unchanged.
2055
Tim Petersde7990b2005-07-17 23:45:23 +00002056- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2057
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002058- SF bug #1229429: PyObject_CallMethod failed to decrement some
2059 reference counts in some error exit cases.
2060
Tim Petersecc6e6a2005-07-10 22:30:55 +00002061- SF bug #1185883: Python's small-object memory allocator took over
2062 a block managed by the platform C library whenever a realloc specified
2063 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002064 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002065 portable way to copy data from the C-managed block into Python's
2066 small-object space without risking a memory fault. Python's small-object
2067 realloc now leaves such blocks under the control of the platform C
2068 realloc.
2069
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002070- SF bug #1232517: An overflow error was not detected properly when
2071 attempting to convert a large float to an int in os.utime().
2072
Raymond Hettinger3296e692005-06-29 23:29:56 +00002073- SF bug #1224347: hex longs now print with lowercase letters just
2074 like their int counterparts.
2075
Michael W. Hudson188d4362005-06-20 16:52:57 +00002076- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2077 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2078 interpreter states; back out that fix and do a better job (see
2079 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2080 for a longer write-up of the problem).
2081
Michael W. Hudsondf888462005-06-03 14:41:55 +00002082- SF patch #1180995: marshal now uses a binary format by default when
2083 serializing floats.
2084
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002085- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2086 the routines that promise to produce IEEE 754 binary representations
2087 of floats now simply copy bytes around.
2088
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002089- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2090 278.
2091
Brett Cannonc3647ac2005-04-26 03:45:26 +00002092- patch #1109424: int, long, float, complex, and unicode now check for the
2093 proper magic slot for type conversions when subclassed. Previously the
2094 magic slot was ignored during conversion. Semantics now match the way
2095 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002096 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002097 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002098 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002099
Barry Warsawc8d907c2005-04-19 23:43:40 +00002100- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2101 NULL, now raise an AttributeError when attempting to set or delete the
2102 attribute. Previously a TypeError was raised, but this was inconsistent
2103 with the equivalent pure-Python implementation.
2104
Michael W. Hudson774479c2005-04-18 08:46:17 +00002105- It is now safe to call PyGILState_Release() before
2106 PyEval_InitThreads() (note that if there is reason to believe there
2107 are multiple threads around you still must call PyEval_InitThreads()
2108 before using the Python API; this fix is for extension modules that
2109 have no way of knowing if Python is multi-threaded yet).
2110
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002111- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2112 disabled caused a crash.
2113
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002114- Bug #1165306: instancemethod_new allowed the creation of a method
2115 with im_class == im_self == NULL, which caused a crash when called.
2116
Tim Petersecc6e6a2005-07-10 22:30:55 +00002117- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002118 fixes the crash seen in bug #1165761
2119
Raymond Hettinger96229b12005-03-11 06:49:40 +00002120- Added two new builtins, any() and all().
2121
Brett Cannon409d8f22005-03-05 06:47:57 +00002122- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002123 (e.g., ``class C(): pass`` is no longer a syntax error).
2124 Patch #1176012 added support to the 'parser' module and 'compiler' package
2125 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002126
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002127- Patch #1115086: Support PY_LONGLONG in structmember.
2128
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002129- Bug #1155938: new style classes did not check that __init__() was
2130 returning None.
2131
Tim Petersecc6e6a2005-07-10 22:30:55 +00002132- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002133 ('\') with a specific error message.
2134
Martin v. Löwisff232d72005-03-03 09:24:38 +00002135- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2136
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002137- Bug #1124295: the __name__ attribute of file objects was
2138 inadvertently made inaccessible in restricted mode.
2139
Tim Petersecc6e6a2005-07-10 22:30:55 +00002140- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002141 an ferror() call.
2142
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002143- min() and max() now support key= arguments with the same meaning as in
2144 list.sort().
2145
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002146- The peephole optimizer now performs simple constant folding in expressions:
2147 (2+3) --> (5).
2148
Raymond Hettingera422c342005-01-11 03:03:27 +00002149- set and frozenset objects can now be marshalled. SF #1098985.
2150
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002151- Bug #1077106: Poor argument checking could cause memory corruption
2152 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002153
Jeremy Hyltonab630502005-02-04 18:44:06 +00002154- The parser did not complain about future statements in illegal
2155 positions. It once again reports a syntax error if a future
2156 statement occurs after anything other than a doc string.
2157
Neil Schemenauercf52c072005-08-12 17:34:58 +00002158- Change the %s format specifier for str objects so that it returns a
2159 unicode instance if the argument is not an instance of basestring and
2160 calling __str__ on the argument returns a unicode instance.
2161
Tim Petersf4e69282006-02-27 17:15:31 +00002162- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2163 current thread state when the auto-GIL-state machinery knows about
2164 it (since the thread state is being deleted, continuing to remember it
2165 can't help, but can hurt if another thread happens to get created with
2166 the same thread id).
2167
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002168Extension Modules
2169-----------------
2170

Neal Norwitz10be10c2006-03-16 06:50:13 +00002184 util, whatsound, whrandom, zmod
2185
2186- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2187
2188- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002189 is deprecated. The undocumented re.engine variable no longer exists.
2190

2192 SS2 (single-shift 2) escape sequences correctly.
2193
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002194- The unicodedata module was updated to the 4.1 version of the Unicode
2195 database. The 3.2 version is still available as unicodedata.db_3_2_0
2196 for applications that require this specific version (such as IDNA).
2197
Neal Norwitzb62c4332006-03-04 18:35:47 +00002198- The timing module is no longer built by default. It was deprecated
2199 in PEP 4 in Python 2.0 or earlier.
2200
Guido van Rossum1968ad32006-02-25 22:38:04 +00002201- Patch 1433928: Added a new type, defaultdict, to the collections module.
2202 This uses the new __missing__ hook behavior added to dict (see above).
2203
Georg Brandldbd83392006-02-20 09:42:33 +00002204- Bug #854823: socketmodule now builds on Sun platforms even when
2205 INET_ADDRSTRLEN is not defined.
2206
Georg Brandlf4f44152006-02-18 22:29:33 +00002207- Patch #1393157: os.startfile() now has an optional argument to specify
2208 a "command verb" to invoke on the file.
2209

2218 than the system default domain.
2219
Martin v. Löwis14694662006-02-03 12:54:16 +00002220- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2221 are reported, the limit on path name lengths is removed, and stat reports
2222 WindowsError now (instead of OSError).
2223
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002224- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2299 the request code argument, which results in more C-like behaviour
2300 for large or negative values.
2301
Tim Petersecc6e6a2005-07-10 22:30:55 +00002302- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2341
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002342- the cPickle module no longer accepts the deprecated None option in the
2343 args tuple returned by __reduce__().
2344
Raymond Hettingerb2594052004-12-05 09:25:51 +00002345- itertools.islice() now accepts None for the start and step arguments.
2346 This allows islice() to work more readily with slices:
2347 islice(s.start, s.stop, s.step)
2348
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002349- datetime.datetime() now has a strptime class method which can be used to

2356-------
Tim Peters112aad32006-07-19 00:03:19 +00002357
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002358- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2359 been renamed to have only a single underscore prefix. This was done to
2360 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002361
Nick Coghlan43832302006-04-23 17:04:07 +00002362- PEP 338: new module runpy defines a run_module function to support
2363 executing modules which provide access to source code or a code object
2364 via the PEP 302 import mechanisms.
2365
Anthony Baxter93f5b932006-04-03 08:05:07 +00002366- The email module's parsedate_tz function now sets the daylight savings
2367 flag to -1 (unknown) since it can't tell from the date whether it should

2374 in attribute values.
2375
Anthony Baxterc51ee692006-04-01 00:57:31 +00002376- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002377 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002378 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002379 module will not be built.
2380
Tim Petersc17976e2006-04-01 00:26:53 +00002381- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2382 aren't officially supported here, and trying to use them will probably
2383 raise an exception some day. But dicts have been allowed, and "mostly
2384 worked", so support for them won't go away without warning.
2385
Georg Brandl338ef7d2006-03-31 18:42:16 +00002386- Bug #1445068: getpass.getpass() can now be given an explicit stream
2387 argument to specify where to write the prompt.
2388
Georg Brandl22ec80b2006-03-31 18:25:44 +00002389- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2396
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002397- Queue.Queue objects now support .task_done() and .join() methods
2398 to make it easier to monitor when daemon threads have completed
2399 processing all enqueued tasks. Patch #1455676.
2400
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002401- popen2.Popen objects now preserve the command in a .cmd attribute.
2402
Thomas Hellerc61c0492006-03-22 10:09:27 +00002403- Added the ctypes ffi package.
2404
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002405- email 4.0 package now integrated. This is largely the same as the email 3.0
2406 package that was included in Python 2.3, except that PEP 8 module names are
2407 now used (e.g. mail.message instead of email.Message). The MIME classes
2408 have been moved to a subpackage (e.g. email.mime.text instead of
2409 email.MIMEText). The old names are still supported for now. Several
2410 deprecated Message methods have been removed and lots of bugs have been
2411 fixed. More details can be found in the email package documentation.
2412
Walter Dörwald40108c92006-03-27 08:15:44 +00002413- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2414 (a subclass of tuple) that provides incremental decoders and encoders
2415 (a way to use stateful codecs without the stream API). Python functions
2416 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2417 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2418 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002419
Walter Dörwald067db482006-03-15 22:17:27 +00002420- Patch #1359365: Calling next() on a closed StringIO.String object raises
2421 a ValueError instead of a StopIteration now (like file and cString.String do).
2422 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2423 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002424
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002425- A regrtest option -w was added to re-run failed tests in verbose mode.

2437 and helpful context managers nested() and closing().
2438

2443
Georg Brandlc98eeed2006-02-19 14:57:47 +00002444- Patch #1215184: FileInput now can be given an opening hook which can

Tim Peterse3547fd2005-12-16 23:13:57 +00002497 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2498 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2499 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2500 Ronald L. Rivest offered this advice for Python:
2501
2502 "The consensus of researchers in this area (at least as
2503 expressed at the NIST Hash Function Workshop 10/31/05),
2504 is that SHA-256 is a good choice for the time being, but
2505 that research should continue, and other alternatives may
2506 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002507
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002508- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002581- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002582 Patch #1209527 (Contributed by Connelly).
2583
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002584- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2585 to W3C name (404 -> 'Not Found'). RFE #1216944.
2586
Georg Brandl9e43acf2005-07-04 17:16:07 +00002587- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2588 as this can cause problems with apps closing all file descriptors.
2589
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002590- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002591 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002592
Georg Brandl2f210b62005-06-26 22:09:06 +00002593- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2594
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002595- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2596 error messages.
2597
Georg Brandl379f99d2005-06-26 21:09:38 +00002598- Bug #1108948: Cookie.py produced invalid JavaScript code.
2599
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002600- The tokenize module now detects and reports indentation errors.
2601 Bug #1224621.
2602
Raymond Hettinger68c04532005-06-10 11:05:19 +00002603- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002604 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002605 the generate_tokens() function now accepts a callable argument that
2606 terminates by raising StopIteration.
2607
Georg Brandl9166e1a2005-06-04 09:20:03 +00002608- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2609
Georg Brandl268e61c2005-06-03 14:28:50 +00002610- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2611 component of the path.
2612
Skip Montanaro174dd222005-05-14 20:54:16 +00002613- Patch #1120353: The xmlrpclib module provides better, more transparent,
2614 support for datetime.{datetime,date,time} objects. With use_datetime set
2615 to True, applications shouldn't have to fiddle with the DateTime wrapper
2616 class at all.
2617
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002618- distutils.commands.upload was added to support uploading distribution
2619 files to PyPI.
2620
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002621- distutils.commands.register now encodes the data as UTF-8 before posting
2622 them to PyPI.
2623
Raymond Hettinger267b8682005-03-27 10:47:39 +00002624- decimal operator and comparison methods now return NotImplemented
2625 instead of raising a TypeError when interacting with other types. This
2626 allows other classes to implement __radd__ style methods and have them
2627 work as expected.
2628
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002629- Bug #1163325: Decimal infinities failed to hash. Attempting to
2630 hash a NaN raised an InvalidOperation instead of a TypeError.
2631
Tim Petersecc6e6a2005-07-10 22:30:55 +00002632- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002633 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2634

2664
Raymond Hettingerbab41432005-02-05 01:31:19 +00002665- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2666
Guido van Rossumd0641422005-02-03 15:01:24 +00002667- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2668 disables recursive traversal through instance attributes, which can
2669 be exploited in various ways.
2670
Tim Peterse3547fd2005-12-16 23:13:57 +00002671- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002672 flags on the HTTP listening socket.
2673
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002674- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2675 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2676
Fred Drakefbdeaad2006-07-29 16:56:15 +00002677- Patches #893642, #1039083: add allow_none, encoding arguments to
2678 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002679
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002680- Bug #1110478: Revert os.environ.update to do putenv again.
2681
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002682- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2683
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002684- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2685
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002686- Enhancements to the csv module:
2687
2688 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002689 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002690 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002691 + Dialect parameter parsing has been re-implemented to improve error
2692 reporting.
2693 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2694 dictates.
2695 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002696 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002697 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002698 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2699 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002700 + reader now allows \r characters to be quoted (previously it only allowed
2701 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002702 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002703 + Dialect classes passed to the module are no longer instantiated by
2704 the module before being parsed (the former validation scheme required
2705 this, but the mechanism was unreliable).
2706 + The dialect registry now contains instances of the internal
2707 C-coded dialect type, rather than references to python objects.
2708 + the internal c-coded dialect type is now immutable.
2709 + register_dialect now accepts the same keyword dialect specifications
2710 as the reader and writer, allowing the user to register dialects
2711 without first creating a dialect class.
2712 + a configurable limit to the size of parsed fields has been added -
2713 previously, an unmatched quote character could result in the entire
2714 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002715 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002716 the parser field size limit (returning the former limit). The initial
2717 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002718 + A line_num attribute has been added to the reader object, which tracks
2719 the number of lines read from the source iterator. This is not
2720 the same as the number of records returned, as records can span
2721 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002722 + reader and writer objects were not being registered with the cyclic-GC.
2723 This has been fixed.
2724
Brett Cannone6539c42005-01-08 02:43:53 +00002725- _DummyThread objects in the threading module now delete self.__block that is
2726 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2727 lock primitives tend to be limited in number and thus should not be wasted on
2728 a _DummyThread object. Fixes bug #1089632.
2729
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002730- The imghdr module now detects Exif files.
2731
Raymond Hettinger6065d322004-12-20 23:51:53 +00002732- StringIO.truncate() now correctly adjusts the size attribute.
2733 (Bug #951915).
2734
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002735- locale.py now uses an updated locale alias table (built using
2736 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2737 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002738 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002739
Raymond Hettinger3557f422004-12-07 12:02:02 +00002740- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2741
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002742- the pickle module no longer accepts the deprecated None option in the
2743 args tuple returned by __reduce__().
2744
Brett Cannon84667c02004-12-07 03:25:18 +00002745- optparse now optionally imports gettext. This allows its use in setup.py.
2746
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002747- the pickle module no longer uses the deprecated bin parameter.
2748
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002749- the shelve module no longer uses the deprecated binary parameter.
2750
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002751- the pstats module no longer uses the deprecated ignore() method.
2752
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002753- the filecmp module no longer uses the deprecated use_statcache argument.
2754
Raymond Hettinger664347b2004-12-04 21:21:53 +00002755- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2756 extended or overridden by subclasses. Formerly, the subclassed method would
2757 be ignored by the rest of the module. (Bug #1078905).
2758
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002759- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002760 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002761
Walter Dörwald36733692004-12-22 12:50:50 +00002762- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2763 once when a size argument is given. This prevents a buffer overflow in the
2764 tokenizer with very long source lines.
2765
Barry Warsaw538561e2006-01-01 21:48:54 +00002766- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2767 immediately after creating the object, without any intervening
2768 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002769
Skip Montanaro05885812005-01-16 20:48:27 +00002770- The reconvert.quote function can now emit triple-quoted strings. The
2771 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002772
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002773- ``UserString.MutableString`` now supports negative indices in
2774 ``__setitem__`` and ``__delitem__``
2775
Greg Ward40407942005-03-05 02:53:17 +00002776- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2777 correctly.
2778
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002779- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2780 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2781 character even if the user has passed a size parameter to get a proper
2782 line ending. Remove the special handling of a "\r\n" that has been split
2783 between two lines.
2784
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002785- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2786 about illegal code points. The codec now supports PEP 293 style error
2787 handlers.
2788
Walter Dörwald78a78b02005-09-01 12:04:29 +00002789- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002790 from the input stream, so that the output is a byte string in the correct
2791 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002792
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002793- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2794 considering it exactly like a '*'.
2795
Walter Dörwald007f8df2005-10-09 19:42:27 +00002796- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2797 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002798
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002799- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2800
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002801- Patch #1413711: Certain patterns of differences were making difflib
2802 touch the recursion limit.
2803
Walter Dörwald58917a62006-03-31 15:26:22 +00002804- Bug #947906: An object oriented interface has been added to the calendar
2805 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002806 called as a script (e.g. via ``python -mcalendar``). Localized month and
2807 weekday names can be ouput (even if an exotic encoding is used) using
2808 special classes that use unicode.

Brett Cannon08cd5982005-04-24 22:26:38 +00002835- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2836 flags that change binary compatibility. Changes were also made to
2837 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002838 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00002840- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2841 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2842 no longer exists). This configure patch makes things right.
2843
Martin v. Löwise2713be2005-03-08 15:03:08 +00002844- Bug #1158607: Build with --disable-unicode again.
2845
Brett Cannon46d96232005-02-16 00:07:19 +00002846- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2847 defined. Discovered as a result of not being able to build on OS X.
2848
Brett Cannon516592f2004-12-07 00:42:59 +00002849- setup.py now uses the directories specified in LDFLAGS using the -L option
2850 and in CPPFLAGS using the -I option for adding library and include
2851 directories, respectively, for compiling extension modules against. This has
2852 led to the core being compiled using the values in CPPFLAGS. It also removes
2853 the need for the special-casing of both DarwinPorts and Fink for darwin since
2854 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2855 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2856 Fink, ``-I/opt/local/include`` for DarwinPorts).
2857
Brett Cannon43802422005-02-10 20:48:03 +00002858- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2859 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2860 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2861 Closes bug #1096244. Thanks Gregory Bond.

2864-----
2865
Tim Petersc9d78aa2006-03-26 23:27:58 +00002866- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2867 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2868 is obtained via the ``PyObject_`` family, it must be released via the
2869 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2870 always been officially true, but when Python's small-object allocator was
2871 introduced, an attempt was made to cater to a few extension modules
2872 discovered at the time that obtained memory via ``PyObject_New`` but
2873 released it via ``PyMem_DEL``. It's years later, and if such code still
2874 exists it will fail now (probably with segfaults, but calling wrong
2875 low-level memory management functions can yield many symptoms).
2876
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002877- Added a C API for set and frozenset objects.
2878
Raymond Hettinger66517482004-12-03 11:45:13 +00002879- Removed PyRange_New().
2880
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002881- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2882 mapping argument now. This string is used as a mapping table. Byte values
2883 greater than the length of the string and 0xFFFE are treated as undefined
2884 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002892- Patch #1276356: New resource "urlfetch" is implemented. This enables
2893 even impatient people to run tests that require remote files.
