700
Brett Cannon19d76c52006-09-09 07:18:44 +0000701- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

721
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000722- Bug #1520864: unpacking singleton tuples in list comprehensions and

838-----------------
839
Neal Norwitz24b6f202006-09-05 04:43:56 +0000840- Fix infinite recursion when subclassing long and overriding __hash__.
841
842- Fix concatenation (+=) of long strings.
843
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000844- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000845 compared equal or unequal to a string and a UnicodeDecodeError
846 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000847
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000848 Instead, the equal (==) and unequal (!=) comparison operators will
849 now issue a UnicodeWarning and interpret the two objects as
850 unequal. The UnicodeWarning can be filtered as desired using
851 the warning framework, e.g. silenced completely, turned into an
852 exception, logged, etc.
853
854 Note that compare operators other than equal and unequal will still
855 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000856
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000857- Fix segfault when doing string formatting on subclasses of long.
858
859- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
860 with new-style classes.
861
862- Fix bug related to __len__ functions returning negative values with
863 classic classes.
864
865- Patch #1538606, Fix __index__() clipping. There were some problems
866 discovered with the API and how integers that didn't fit into Py_ssize_t
867 were handled. This patch attempts to provide enough alternatives
868 to effectively use __index__.
869
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000870- Bug #1536021: __hash__ may now return long int; the final hash
871 value is obtained by invoking hash on the long int.
872
Thomas Hellerab1049c2006-08-08 17:37:00 +0000873- Bug #1536786: buffer comparison could emit a RuntimeWarning.

879 the Python dll again.
880
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000881- Bug #1191458: tracing over for loops now produces a line event
882 on each iteration. Fixing this problem required changing the .pyc
883 magic number. This means that .pyc files generated before 2.5c1
884 will be regenerated.
885
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000886- Bug #1333982: string/number constants were inappropriately stored
887 in the byte code and co_consts even if they were not used, ie

Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000896- Fix a bug in the ``compiler`` package that caused invalid code to be
897 generated for generator expressions.
898
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000899- The distutils version has been changed to 2.5.0. The change to
900 keep it programmatically in sync with the Python version running
901 the code (introduced in 2.5b3) has been reverted. It will continue
902 to be maintained manually as static string literal.
903
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000904- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000905 and this cannot be converted to the required C type, an exception is
906 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000907 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000908
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000909- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000910 an exception.
911
Tim Peterscbdd3502006-09-05 01:47:53 +0000912- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000913 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000914 workarounds for clocks with low resolution, to stop the code yielding
915 duplicate UUIDs.
916
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000917- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
918 before raising SystemExit, allowing IDLE to honor quit() and exit().
919
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000920- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
921
Georg Brandl7a1af772006-08-14 21:55:28 +0000922- Patch #1536071: trace.py should now find the full module name of a
923 file correctly even on Windows.
924
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000925- logging's atexit hook now runs even if the rest of the module has
926 already been cleaned up.
927
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000928- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000929
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000930- Bug #1531405, format_exception no longer raises an exception if
931 str(exception) raised an exception.
932
Neil Schemenauer06ded092006-08-04 16:20:30 +0000933- Fix a bug in the ``compiler`` package that caused invalid code to be
934 generated for nested functions.
935
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000936
937Extension Modules

941
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000942- Patch #1511317: don't crash on invalid hostname (alias) info.
943
Georg Brandl3335a7a2006-08-14 21:42:55 +0000944- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
945 raises the correct exceptions.
946
Thomas Heller1ce433e2006-08-14 16:20:04 +0000947- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
948 '-no-stack-protector' compiler flag for OpenBSD has been removed.
949
Thomas Heller86720042006-08-14 11:17:48 +0000950- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
951 uses the _as_parameter_ attribute when objects are passed to foreign
952 function calls. The ctypes version number was changed to 1.0.1.
953
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000954- Bug #1530559, struct.pack raises TypeError where it used to convert.
955 Passing float arguments to struct.pack when integers are expected
956 now triggers a DeprecationWarning.
957
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000958

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000979Build
980-----
981
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000982- Bug #1535502, build _hashlib on Windows, and use masm assembler
983 code in OpenSSL.
984
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000985- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
986
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000987- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +0000988
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000989
Tim Peters4643c2f2006-08-10 22:45:34 +0000990C API
991-----
992
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000993- New API for Unicode rich comparisons: PyUnicode_RichCompare()
994
Tim Peters4643c2f2006-08-10 22:45:34 +0000995- Bug #1069160. Internal correctness changes were made to
996 ``PyThreadState_SetAsyncExc()``. A test case was added, and
997 the documentation was changed to state that the return value
998 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001001What's New in Python 2.5 beta 3?
1002================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001003
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001004*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001005
1006Core and builtins
1007-----------------
1008
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001009- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001010 returned a long (see PEP 353).
1011
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001012- Bug #1515471: string.replace() accepts character buffers again.
1013
Neal Norwitz07aadb12006-07-30 06:55:48 +00001014- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1015 This provides the proper warning for struct.pack().
1016 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1017
Neal Norwitz0d62a062006-07-30 06:53:31 +00001018- Patch #1531113: Fix augmented assignment with yield expressions.
1019 Also fix a SystemError when trying to assign to yield expressions.
1020
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001021- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1022 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1023 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1024 excessive filesystem operations during imports.
1025
Tim Petersbc24eee2006-07-27 01:14:53 +00001026- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1027 operations on signed longs that are formally undefined by C.
1028 Unfortunately, at least one compiler now cares about that, so complicated
1029 the code to make that compiler happy again.
1030
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001031- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1032
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001033- Patch #1232023: Stop including current directory in search
1034 path on Windows.
1035
Neal Norwitze1fdb322006-07-21 05:32:28 +00001036- Fix some potential crashes found with failmalloc.
1037
Neal Norwitze7563102006-07-17 01:00:16 +00001038- Fix warnings reported by Klocwork's static analysis tool.
1039
Neal Norwitz84be93b2006-07-16 01:50:38 +00001040- Bug #1512814, Fix incorrect lineno's when code within a function
1041 had more than 255 blank lines.
1042
Georg Brandl9dceedb2006-07-12 15:31:17 +00001043- Patch #1521179: Python now accepts the standard options ``--help`` and
1044 ``--version`` as well as ``/?`` on Windows.
1045
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001046- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001047 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001048 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001049
Tim Peters112aad32006-07-19 00:03:19 +00001050- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001051 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001052 new ``sys._current_frames()`` returns a dictionary with one entry,
1053 mapping the faux "thread id" 0 to the current frame.
1054
Ronald Oussoren3075e162006-07-25 20:28:55 +00001055- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001056
Ronald Oussoren3075e162006-07-25 20:28:55 +00001057
Neal Norwitza1f10902006-07-12 07:28:29 +00001058Library
1059-------
1060
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001061- Correction of patch #1455898: In the mbcs decoder, set final=False
1062 for stream decoder, but final=True for the decode function.
1063
Georg Brandl07fec3a2006-08-01 18:49:24 +00001064- os.urandom no longer masks unrelated exceptions like SystemExit or
1065 KeyboardInterrupt.
1066
Tim Peters4643c2f2006-08-10 22:45:34 +00001067- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001068 shutil.copytree on Windows
1069
Georg Brandle34ac7c2006-07-30 11:07:23 +00001070- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1071 refers to file descriptors, not file objects.
1072
Tim Peterscbdd3502006-09-05 01:47:53 +00001073- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001074 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001075 #1513611, and probably others.
1076
Georg Brandledd9b0d2006-07-29 09:33:26 +00001077- Bug #1441397: The compiler module now recognizes module and function
1078 docstrings correctly as it did in Python 2.4.
1079
Tim Peters6f681472006-07-27 23:44:37 +00001080- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1081 lost that tests are sorted by name before being run. This rarely
1082 matters for well-written tests, but can create baffling symptoms if
1083 side effects from one test to the next affect outcomes. ``DocTestFinder``
1084 has been changed to sort the list of tests it returns.
1085
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001086- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001087 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001088
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001089- Bug #978833: Really close underlying socket in _socketobject.close.
1090
Georg Brandldb232dc2006-08-20 13:15:43 +00001091- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1092 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001093
Georg Brandlcf0c1722006-07-26 07:23:32 +00001094- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1095 to recursive calls and call it with the failing package name.
1096
Martin v. Löwis0b483032006-07-25 09:53:12 +00001097- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1098
Georg Brandlc13c34c2006-07-24 14:09:56 +00001099- Patch #1515343: Fix printing of deprecated string exceptions with a
1100 value in the traceback module.
1101
Greg Ward48fae7a2006-07-23 16:05:51 +00001102- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1103
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001104- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1105
Brett Cannoncaebe222006-07-18 04:41:36 +00001106- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1107 argument tuple. For arguments where zero is illegal, the value is forced to
1108 the minimum value that is correct. This is to support an undocumented but
1109 common way people used to fill in inconsequential information in the time
1110 tuple pre-2.4.
1111
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001112- Patch #1220874: Update the binhex module for Mach-O.
1113
Barry Warsawb110bad2006-07-21 14:51:07 +00001114- The email package has improved RFC 2231 support, specifically for
1115 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1116 (name*0=<blah>) parameter continuations. This may change the types of
1117 values returned from email.message.Message.get_param() and friends.
1118 Specifically in some cases where non-encoded continuations were used,
1119 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1120 will just return the string (since non-encoded continuations don't have
1121 charset and language parts).
1122
1123 Also, whereas % values were decoded in all parameter continuations, they are
1124 now only decoded in encoded parameter parts.
1125
Ronald Oussoren3075e162006-07-25 20:28:55 +00001126- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1127
1128- Bug #1517996: IDLE now longer shows the default Tk menu when a
1129 path browser, class browser or debugger is the frontmost window on MacOS X
1130
Barry Warsaw00decd72006-07-27 23:43:15 +00001131- Patch #1520294: Support for getset and member descriptors in types.py,
1132 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1133 of an object against these built-in types and more importantly, for getting
1134 their docstrings printed in the interactive interpreter's help() function.
1135

Neal Norwitza1f10902006-07-12 07:28:29 +00001137Extension Modules
1138-----------------
1139
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001140- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1141 a socket operation on a socket with a timeout, the exception will be
1142 caught correctly. Previously, the exception was not caught.
1143
Thomas Heller1393d6a2006-07-28 21:43:20 +00001144- Patch #1529514: The _ctypes extension is now compiled on more
1145 openbsd target platforms.
1146
Tim Peters9cab5932006-07-28 00:30:00 +00001147- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1148 a memory leak, affecting pickles and deep copies.
1149
Tim Petersbc24eee2006-07-27 01:14:53 +00001150- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001151 Paul Eggert.
1152
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001153- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1154
Thomas Hellerce049a02006-07-14 17:51:14 +00001155- Patch #1521817: Index range checking on ctypes arrays containing
1156 exactly one element enabled again. This allows iterating over these
1157 arrays, without the need to check the array size before.
1158
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001159- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001160 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001161 /dev/null in certain cases; this is now fixed.
1162
Thomas Heller47d7a062006-07-12 08:43:47 +00001163- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1164 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001165
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001166- Because of a misspelled preprocessor symbol, ctypes was always
1167 compiled without thread support; this is now fixed.
1168
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001169- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1170 methods now allow their database parameter to be None as the
1171 sleepycat API allows.

Matt Flemingec926502006-07-28 11:27:27 +00001173- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1174 bluetooth API compared with Linux and FreeBSD.
1175
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001176Tests
1177-----
1178
1179- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1180 how long the test file should take to play. Now accepts taking 2.93 secs
1181 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1182
Georg Brandl4793aa32006-07-28 18:31:39 +00001183- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1184 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1185 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001192Mac
1193---
1194
1195- PythonLauncher now works correctly when the path to the script contains
1196 characters that are treated specially by the shell (such as quotes).
1197
1198- Bug #1527397: PythonLauncher now launches scripts with the working directory
1199 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001200 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001201 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001208
1209Core and builtins
1210-----------------
1211
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001212- Bug #1441486: The literal representation of -(sys.maxint - 1)
1213 again evaluates to a int object, not a long.
1214
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001215- Bug #1501934: The scope of global variables that are locally assigned
1216 using augmented assignment is now correctly determined.
1217
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001218- Bug #927248: Recursive method-wrapper objects can now safely
1219 be released.
1220
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001221- Bug #1417699: Reject locale-specific decimal point in float()
1222 and atof().
1223
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001224- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1225 omit a default "error" argument for NULL pointer. This allows
1226 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001227
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001228- Bug #1519018: 'as' is now validated properly in import statements.
1229
Neal Norwitz28746ab2006-07-09 22:14:42 +00001230- On 64 bit systems, int literals that use less than 64 bits are
1231 now ints rather than longs.
1232
Neal Norwitzed657552006-07-10 00:04:44 +00001233- Bug #1512814, Fix incorrect lineno's when code at module scope
1234 started after line 256.
1235
Tim Peters32a83612006-07-10 21:08:24 +00001236- New function ``sys._current_frames()`` returns a dict mapping thread
1237 id to topmost thread stack frame. This is for expert use, and is
1238 especially useful for debugging application deadlocks. The functionality
1239 was previously available in Fazal Majid's ``threadframe`` extension
1240 module, but it wasn't possible to do this in a wholly threadsafe way from
1241 an extension.
1242

1250
Tim Peters32a83612006-07-10 21:08:24 +00001251- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001252 environment variable to be set in order to the SDK environment
1253 for finding the compiler, include files, etc.

1256
Nick Coghlan2d792252006-07-06 13:47:18 +00001257- warnings.py now ignores ImportWarning by default
1258
Thomas Woutersadd19112006-07-05 11:03:49 +00001259- string.Template() now correctly handles tuple-values. Previously,
1260 multi-value tuples would raise an exception and single-value tuples would
1261 be treated as the value they contain, instead.
1262
Martin v. Löwisede77f52006-07-03 13:01:35 +00001263- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1264 even if some data are received.
1265
Martin v. Löwis45482392006-07-03 12:28:58 +00001266- Bug #1267547: Put proper recursive setup.py call into the
1267 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001269- Bug #1514693: Update turtle's heading when switching between
1270 degrees and radians.
1271
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001272- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001273 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001274
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001275- Bug #1514703: Only setup canvas window in turtle when the canvas
1276 is created.
1277
Martin v. Löwis7596e832006-07-01 15:33:37 +00001278- Bug #1513223: .close() of a _socketobj now releases the underlying
1279 socket again, which then gets closed as it becomes unreferenced.

1282 attribute values.
1283
1284- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1285 sgmllib ('[' and ']' were not accepted).
1286
Georg Brandl1be63af2006-06-28 20:23:25 +00001287- Fix a bug in the turtle module's end_fill function.
1288
Brett Cannon53ab5b72006-06-22 16:49:14 +00001289- Bug #1510580: The 'warnings' module improperly required that a Warning
1290 category be either a types.ClassType and a subclass of Warning. The proper
1291 check is just that it is a subclass with Warning as the documentation states.
1292
Georg Brandlad29e632006-06-21 17:45:17 +00001293- The compiler module now correctly compiles the new try-except-finally
1294 statement (bug #1509132).
1295
Neal Norwitz60373cd2006-06-22 06:30:50 +00001296- The wsgiref package is now installed properly on Unix.
1297
Vinay Sajip28e57612006-07-01 10:45:20 +00001298- A bug was fixed in logging.config.fileConfig() which caused a crash on
1299 shutdown when fileConfig() was called multiple times.
1300
Gerhard Häring762fbd32006-07-02 17:48:30 +00001301- The sqlite3 module did cut off data from the SQLite database at the first
1302 null character before sending it to a custom converter. This has been fixed
1303 now.
1304
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001305Extension Modules
1306-----------------
1307
Tim Peters112aad32006-07-19 00:03:19 +00001308- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1309 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1310 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001311
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001312- Assigning None to pointer type fields in ctypes structures possible
1313 overwrote the wrong fields, this is fixed now.
1314
1315- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1316 on non-Windows platforms.
1317
1318- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1319 integer or long, without range checking.
1320
1321- Patch #1517790: It is now possible to use custom objects in the ctypes
1322 foreign function argtypes sequence as long as they provide a from_param
1323 method, no longer is it required that the object is a ctypes type.
1324
1325- The '_ctypes' extension module now works when Python is configured
1326 with the --without-threads option.
1327
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001328- Bug #1513646: os.access on Windows now correctly determines write
1329 access, again.
1330
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001331- Bug #1512695: cPickle.loads could crash if it was interrupted with
1332 a KeyboardInterrupt.
1333
Neal Norwitza12aa882006-07-06 06:45:08 +00001334- Bug #1296433: parsing XML with a non-default encoding and
1335 a CharacterDataHandler could crash the interpreter in pyexpat.
1336
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001337- Patch #1516912: improve Modules support for OpenVMS.
1338
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001339Build
1340-----
1341
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001342- Automate Windows build process for the Win64 SSL module.
1343
Tim Peters32a83612006-07-10 21:08:24 +00001344- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001345 Previously, the slight difference could cause compilation errors of the
1346 'zlib' module on systems with more than one version of zlib.
1347
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001348- The MSI compileall step was fixed to also support a TARGETDIR
1349 with spaces in it.
1350
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001351- Bug #1517388: sqlite3.dll is now installed on Windows independent
1352 of Tcl/Tk.
1353
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001354- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001355 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001357Tests
1358-----
1359
1360- Call os.waitpid() at the end of tests that spawn child processes in order
1361 to minimize resources (zombies).
1362
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001363Documentation
1364-------------
1365
Nick Coghlan2d792252006-07-06 13:47:18 +00001366- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1367 documentation for the warnings module.
1368
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001369- Patch #1509163: MS Toolkit Compiler no longer available.
1370
Neal Norwitz56640df2006-07-10 02:36:41 +00001371- Patch #1504046: Add documentation for xml.etree.

Georg Brandlad29e632006-06-21 17:45:17 +00001375================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001376
Anthony Baxterd1136802006-06-19 12:04:15 +00001377*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001378
1379Core and builtins
1380-----------------
1381
Georg Brandla56b9152006-06-19 06:35:54 +00001382- Patch #1507676: Error messages returned by invalid abstract object operations
1383 (such as iterating over an integer) have been improved and now include the
1384 type of the offending object to help with debugging.
1385
Brett Cannonea3912b2006-06-13 21:46:41 +00001386- Bug #992017: A classic class that defined a __coerce__() method that returned
1387 its arguments swapped would infinitely recurse and segfault the interpreter.
1388
Neal Norwitz909eb122006-06-12 02:13:21 +00001389- Fix the socket tests so they can be run concurrently.
1390
Neal Norwitzb9845e72006-06-12 02:11:18 +00001391- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001392 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001393
Brett Cannon22565aa2006-06-09 22:31:23 +00001394- Bug #532646: object.__call__() will continue looking for the __call__
1395 attribute on objects until one without one is found. This leads to recursion
1396 when you take a class and set its __call__ attribute to an instance of the
1397 class. Originally fixed for classic classes, but this fix is for new-style.
1398 Removes the infinite_rec_3 crasher.
1399
Georg Brandl24250812006-06-09 18:45:48 +00001400- The string and unicode methods startswith() and endswith() now accept
1401 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1402
Brett Cannonde3b0522006-06-08 17:00:45 +00001403- Buffer objects, at the C level, never used the char buffer
1404 implementation even when the char buffer for the wrapped object was
1405 explicitly requested (originally returned the read or write buffer).
1406 Now a TypeError is raised if the char buffer is not present but is
1407 requested.
1408
Georg Brandlddbaa662006-06-04 21:56:52 +00001409- Patch #1346214: Statements like "if 0: suite" are now again optimized
1410 away like they were in Python 2.4.
1411
Georg Brandlb7c8f542006-05-27 12:30:25 +00001412- Builtin exceptions are now full-blown new-style classes instead of
1413 instances pretending to be classes, which speeds up exception handling
1414 by about 80% in comparison to 2.5a2.
1415
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001416- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1417 Unicode 4.1.
1418
Georg Brandlf4ef1162006-05-26 18:03:31 +00001419- Patch #921466: sys.path_importer_cache is now used to cache valid and
1420 invalid file paths for the built-in import machinery which leads to
1421 fewer open calls on startup.
1422
Tim Peters696cf432006-05-24 21:10:40 +00001423- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1424 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1425 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1426 the number of input digits (it was and remains linear-time for bases
1427 2, 4, 8, 16 and 32).
1428
Tim Petersb713ec22006-05-23 18:45:30 +00001429- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1430 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1431 an integer close to ``sys.maxint``. This was repaired by patch
1432 #1335972, which also gives a nice speedup.
1433
Richard Jonescebbefc2006-05-23 18:28:17 +00001434- Patch #1337051: reduced size of frame objects.
1435
1436- PyErr_NewException now accepts a tuple of base classes as its
1437 "base" parameter.
1438
Richard Jones7c88dcc2006-05-23 10:37:38 +00001439- Patch #876206: function call speedup by retaining allocated frame
1440 objects.
1441
Georg Brandl7b90e162006-05-18 07:01:27 +00001442- Bug #1462152: file() now checks more thoroughly for invalid mode
1443 strings and removes a possible "U" before passing the mode to the
1444 C library function.
1445
Neal Norwitz1004a532006-05-15 07:17:23 +00001446- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1447
Neal Norwitz373f0a72006-05-15 07:04:36 +00001448- Bug #1487966: Fix SystemError with conditional expression in assignment
1449
Martin v. Löwis879768d2006-05-11 13:28:43 +00001450- WindowsError now has two error code attributes: errno, which carries
1451 the error values from errno.h, and winerror, which carries the error
1452 values from winerror.h. Previous versions put the winerror.h values
1453 (from GetLastError()) into the errno attribute.
1454
Martin v. Löwis77736712006-05-04 05:51:03 +00001455- Patch #1475845: Raise IndentationError for unexpected indent.
1456
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001457- Patch #1479181: split open() and file() from being aliases for each other.
1458
Tim Peters44bd9862006-06-01 13:49:23 +00001459- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1460 methods were always silently ignored by dictionaries when comparing keys.
1461 They are now passed through (except when using the C API function
1462 ``PyDict_GetItem()``, whose semantics did not change).
1463
1464- Bug #1456209: In some obscure cases it was possible for a class with a
1465 custom ``__eq__()`` method to confuse dict internals when class instances
1466 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1467 No, you don't have any code that did this ;-)

1474- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1475
Brett Cannon6ee7d012006-06-08 16:23:04 +00001476- Change binascii.hexlify to accept a read-only buffer instead of only a char
1477 buffer and actually follow its documentation.
1478
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001479- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1480
Nick Coghlanc649ec52006-05-29 12:43:05 +00001481- Patch #1478788 (modified version): The functional extension module has
1482 been renamed to _functools and a functools Python wrapper module added.
1483 This provides a home for additional function related utilities that are
1484 not specifically about functional programming. See PEP 309.
1485
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001486- Patch #1493701: performance enhancements for struct module.
1487
Georg Brandl378d5922006-05-17 14:26:50 +00001488- Patch #1490224: time.altzone is now set correctly on Cygwin.
1489
Georg Brandl8d3342b2006-05-16 07:38:27 +00001490- Patch #1435422: zlib's compress and decompress objects now have a
1491 copy() method.
1492
Andrew MacIntyre92913322006-06-13 15:04:24 +00001493- Patch #1454481: thread stack size is now tunable at runtime for thread
1494 enabled builds on Windows and systems with Posix threads support.
1495
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001496- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1497 (up to the system limit of 32K characters).
1498
1499- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1500 As a result, these functions now raise WindowsError instead of OSError.
1501
Tim Peters7a822da2006-05-25 21:50:17 +00001502- ``time.clock()`` on Win64 should use the high-performance Windows
1503 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1504 Windows platforms).
1505
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001506- Calling Tk_Init twice is refused if the first call failed as that
1507 may deadlock.
1508
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001509- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1510 accept it without potentially using an uninitialized pointer.
1511
1512- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1513 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1514 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001515
Gregory P. Smith372b5832006-06-05 18:48:21 +00001516- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001517 [pybsddb project SF patch number 1466734]
1518
Gregory P. Smith372b5832006-06-05 18:48:21 +00001519- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1520 parameter is supplied. [SF pybsddb bug #1477863]
1521
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001522- bsddb: the __len__ method of a DB object has been fixed to return correct
1523 results. It could previously incorrectly return 0 in some cases.
1524 Fixes SF bug 1493322 (pybsddb bug 1184012).
1525
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001526- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1527 aborts the db transaction safely when a modifier callback fails.
1528 Fixes SF python patch/bug #1408584.
1529
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001530- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001531 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001532 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1533 database calls that would previously deadlock. [SF python bug #775414]
1534
Vinay Sajip28e57612006-07-01 10:45:20 +00001535- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1557 mime.types file for determining MIME types.
1558
Georg Brandl2605ca82006-06-14 06:08:31 +00001559- Bug #1339007: Shelf objects now don't raise an exception in their
1560 __del__ method when initialization failed.
1561
Martin v. Löwisd8251432006-06-14 05:21:04 +00001562- Patch #1455898: The MBCS codec now supports the incremental mode for
1563 double-byte encodings.
1564
Tim Peters43898b42006-06-14 04:09:25 +00001565- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1566 guarantee that adjacent triples in the return list always describe
1567 non-adjacent blocks. Previously, a pair of matching blocks could end
1568 up being described by multiple adjacent triples that formed a partition
1569 of the matching pair.
1570
Greg Ward0e0c9f42006-06-11 16:24:11 +00001571- Bug #1498146: fix optparse to handle Unicode strings in option help,
1572 description, and epilog.
1573

Greg Ward7f547402006-06-11 00:40:49 +00001576- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1577 clarify docs.
1578
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001579- The wsgiref package has been added to the standard library.
1580
Nick Coghlan676725d2006-06-08 13:54:49 +00001581- The functions update_wrapper() and wraps() have been added to the functools
1582 module. These make it easier to copy relevant metadata from the original
1583 function when writing wrapper functions.
1584
Tim Petersd6a9eef2006-06-05 01:48:21 +00001585- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1586 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001587
Martin v. Löwis3f767792006-06-04 19:36:28 +00001588- Patch #1359618: Speed up charmap encoder by using a trie structure
1589 for lookup.
1590
Tim Petersd609b1a2006-06-02 23:22:51 +00001591- The functions in the ``pprint`` module now sort dictionaries by key
1592 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1593 if and only if its display required more than one line, although that
1594 wasn't documented. The new behavior increases predictability; e.g.,
1595 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1596
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001597- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1599
Georg Brandl2b330372006-05-28 20:23:12 +00001600- Patch #1496206: improve urllib2 handling of passwords with respect to
1601 default HTTP and HTTPS ports.
1602
George Yoshidaf3c65de2006-05-28 16:39:09 +00001603- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1604
Bob Ippolito7298f272006-05-23 18:43:47 +00001605- Patch #1281707: speed up gzip.readline.
1606
Georg Brandlb89316f2006-05-17 15:51:16 +00001607- Patch #1180296: Two new functions were added to the locale module:
1608 format_string() to get the effect of "format % items" but locale-aware,
1609 and currency() to format a monetary number with currency sign.
1610
Georg Brandle3a25832006-05-17 14:56:04 +00001611- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1612 and several features added, such as speed and geometry control.
1613
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001614- Patch #1488881: add support for external file objects in bz2 compressed
1615 tarfiles.
1616
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001617- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1618 stdout arguments, making it possible to redirect input and output
1619 for remote debugging.
1620
1621- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1622 a couple of issues, notably handling of long file names using the
1623 GNU LONGNAME extension.
1624
1625- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1626 new flag when ``name`` is already the name of an option flag.
1627
1628- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1629 package.
1630
1631- Patch #1472854: make the rlcompleter.Completer class usable on non-
1632 UNIX platforms.

1673-----------------
1674
Thomas Heller1b046642006-04-18 18:51:06 +00001675- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1676 by converting these apis from macros into exported functions again:
1677
1678 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1679 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1680 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1681 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1682 PyRun_String Py_CompileString
1683
Martin v. Löwis45294a92006-04-18 06:24:08 +00001684- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1685
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001686- All uses of PyStructSequence_InitType have been changed to initialize
1687 the type objects only once, even if the interpreter is initialized
1688 multiple times.
1689
Neal Norwitz61546162006-04-14 05:20:28 +00001690- Bug #1454485, array.array('u') could crash the interpreter. This was
1691 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1692 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1693
1694- Py_UNICODE is unsigned. It was always documented as unsigned, but
1695 due to a bug had a signed value in previous versions.
1696
Tim Peters3a5e8b12006-04-11 01:44:07 +00001697- Patch #837242: ``id()`` of any Python object always gives a positive
1698 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1699 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001700 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001701 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001702
Tim Peters3a5e8b12006-04-11 01:44:07 +00001703 def __hash__(self):
1704 return id(self) # WRONG
1705
1706 because a hash result must be a (short) Python int but it was always
1707 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001708 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001709 was always usable as a hash value before this patch. That's no longer
1710 necessarily so.
1711
1712- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001713 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001714 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001715 #1454844)
1716
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001717- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1718 involving generators that have paused outside of any ``try`` or ``with``
1719 blocks. (In 2.5a1, a paused generator that was part of a reference
1720 cycle could not be garbage collected, regardless of whether it was
1721 paused in a ``try`` or ``with`` block.)

1733
1734- Bug #1117761: bsddb.*open() no longer raises an exception when using
1735 the cachesize parameter.
1736
1737- Bug #1149413: bsddb.*open() no longer raises an exception when using
1738 a temporary db (file=None) with the 'n' flag to truncate on open.
1739
1740- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1741 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001742
Armin Rigoa9017c32006-04-19 11:50:27 +00001743- Patch #1062014: AF_UNIX sockets under Linux have a special

1747-------
1748
Peter Astrand7d1d4362006-07-14 14:04:45 +00001749- Bug #1223937: subprocess.CalledProcessError reports the exit status
1750 of the process using the returncode attribute, instead of
1751 abusing errno.
1752
Tim Peters711bf302006-04-25 03:31:36 +00001753- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1754 a doctest to be skipped (the code is not run, and the expected output
1755 or exception is ignored).
1756
Nick Coghlanda2268f2006-04-24 04:37:15 +00001757- Fixed contextlib.nested to cope with exceptions being raised and
1758 caught inside exit handlers.
1759
Greg Wardab05edc2006-04-23 03:47:58 +00001760- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1761 hex, octal, or binary; add ``append_const`` action; keep going if
1762 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1763 added ``epilog`` for better help generation).
1764
Tim Peters21fbd572006-04-21 21:18:10 +00001765- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1766 called from a thread spawned as a side effect of importing a module.
1767
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001768- The pydoc module now supports documenting packages contained in
1769 .zip or .egg files.
1770
1771- The pkgutil module now has several new utility functions, such
1772 as ``walk_packages()`` to support working with packages that are either
1773 in the filesystem or zip files.
1774
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001775- The mailbox module can now modify and delete messages from
1776 mailboxes, in addition to simply reading them. Thanks to Gregory
1777 K. Johnson for writing the code, and to the 2005 Google Summer of

1805
Anthony Baxter51bcb682006-04-05 14:51:42 +00001806Build
1807-----
1808
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001809- The Makefile now has a reindent target, which runs reindent.py on
1810 the library.
1811

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001815
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001816- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1817 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001818 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001819 CXX from --with-cxx-main, see description in README.
1820
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001821- Patch #1429775: Link extension modules with the shared libpython.
1822

1826 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1827 and "%zu" for unsigned integers of type ``size_t``.
1828
Anthony Baxter51bcb682006-04-05 14:51:42 +00001829Tests
1830-----
1831
Nick Coghlanda2268f2006-04-24 04:37:15 +00001832- test_contextlib now checks contextlib.nested can cope with exceptions
1833 being raised and caught inside exit handlers.
1834
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001835- test_cmd_line now checks operation of the -m and -c command switches
1836
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001837- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1838 it separately and by hand. It also wasn't cleaning up its changes to
1839 the current Decimal context.
1840
Thomas Woutersabd08882006-04-26 15:53:30 +00001841- regrtest.py now has a -M option to run tests that test the new limits of
1842 containers, on 64-bit architectures. Running these tests is only sensible
1843 on 64-bit machines with more than two gigabytes of memory. The argument
1844 passed is the maximum amount of memory for the tests to use.
1845
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001846Tools
1847-----

Anthony Baxter51bcb682006-04-05 14:51:42 +00001852Documentation
1853-------------
1854
Tim Petersb06d28c2006-05-12 01:57:59 +00001855- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1856
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001857- PEP 343: Added Context Types section to the library reference
1858 and attempted to bring other PEP 343 related documentation into
1859 line with the implementation and/or python-dev discussions.
1860
Tim Peters8dc73d22006-04-24 02:03:16 +00001861- Bug #1337990: clarified that ``doctest`` does not support examples
1862 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001863

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001865What's New in Python 2.5 alpha 1?
1866=================================
1867
Anthony Baxterebed3f62006-04-03 15:03:44 +00001868*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001869
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001870Core and builtins
1871-----------------
1872
Nick Coghlan43832302006-04-23 17:04:07 +00001873- PEP 338: -m command line switch now delegates to runpy.run_module
1874 allowing it to support modules in packages and zipfiles
1875
Martin v. Löwisc661b882006-04-20 04:54:23 +00001876- On Windows, .DLL is not an accepted file name extension for
1877 extension modules anymore; extensions are only found if they
1878 end in .PYD.
1879
Martin v. Löwisea62d252006-04-03 10:56:49 +00001880- Bug #1421664: sys.stderr.encoding is now set to the same value as
1881 sys.stdout.encoding.
1882
Neal Norwitz92e212f2006-04-03 04:48:37 +00001883- __import__ accepts keyword arguments.
1884
Georg Brandlccadf842006-03-31 18:54:53 +00001885- Patch #1460496: round() now accepts keyword arguments.
1886
Anthony Baxter262c00a2006-03-30 10:53:17 +00001887- Fixed bug #1459029 - unicode reprs were double-escaped.
1888
Hye-Shik Changd478f342006-03-23 12:32:36 +00001889- Patch #1396919: The system scope threads are reenabled on FreeBSD
1890 5.4 and later versions.
1891
Neal Norwitze98ccf62006-03-23 05:39:47 +00001892- Bug #1115379: Compiling a Unicode string with an encoding declaration
1893 now gives a SyntaxError.
1894
Georg Brandlabd1ff82006-03-18 07:59:59 +00001895- Previously, Python code had no easy way to access the contents of a
1896 cell object. Now, a ``cell_contents`` attribute has been added
1897 (closes patch #1170323).
1898
Tim Peterscf79aac2006-03-16 01:14:46 +00001899- Patch #1123430: Python's small-object allocator now returns an arena to
1900 the system ``free()`` when all memory within an arena becomes unused
1901 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1902 freed. Some applications will see a drop in virtual memory size now,
1903 especially long-running applications that, from time to time, temporarily
1904 use a large number of small objects. Note that when Python returns an
1905 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001906 platform C library will in turn return that memory to the operating system.
1907 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001908 appears to be effective at least on Microsoft C and gcc-based systems.
1909 Thanks to Evan Jones for hard work and patience.
1910
Georg Brandl533ff6f2006-03-08 18:09:27 +00001911- Patch #1434038: property() now uses the getter's docstring if there is
1912 no "doc" argument given. This makes it possible to legitimately use
1913 property() as a decorator to produce a read-only property.
1914
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001915- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1916 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1917 of requiring an int or long in slicing and a few other contexts, enabling
1918 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1919
Neal Norwitz995acdf2006-03-07 05:01:00 +00001920- Fixed various bugs reported by Coverity's Prevent tool.
1921
Brett Cannonbf364092006-03-01 04:25:17 +00001922- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1923 new exception base class, BaseException, which has a new message attribute.
1924 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1925 Raising a string exception now raises a DeprecationWarning.
1926
Thomas Woutersfb609f42006-02-28 16:37:25 +00001927- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1928 explicitly relative, using 'from .module import name' to mean 'from the same
1929 package as this module is in. Imports without dots still default to the
1930 old relative-then-absolute, unless 'from __future__ import
1931 absolute_import' is used.
1932
Brett Cannona7446e32006-02-27 23:39:10 +00001933- Properly check if 'warnings' raises an exception (usually when a filter set
1934 to "error" is triggered) when raising a warning for raising string
1935 exceptions.
1936
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001937- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001938 The name was removed from Include/code.h.
1939
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001940- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001941
Guido van Rossum1968ad32006-02-25 22:38:04 +00001942- Patch 1433928:
1943 - The copy module now "copies" function objects (as atomic objects).
1944 - dict.__getitem__ now looks for a __missing__ hook before raising
1945 KeyError.
1946
Tim Peters84ef21c2006-02-28 20:39:06 +00001947- PEP 343: with statement implemented. Needs ``from __future__ import
1948 with_statement``. Use of 'with' as a variable will generate a warning.
1949 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001950 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001951 The following objects have __context__ methods:
1952 - The built-in file type.
1953 - The thread.LockType type.
1954 - The following types defined by the threading module:
1955 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1956 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001957
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001958- Fix the encodings package codec search function to only search
1959 inside its own package. Fixes problem reported in patch #1433198.
1960
1961 Note: Codec packages should implement and register their own
1962 codec search function. PEP 100 has the details.
1963
Tim Peters9ea89d22006-06-04 03:26:02 +00001964- PEP 353: Using ``Py_ssize_t`` as the index type.
1965
1966- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1967 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1968 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1969 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1970 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001971
Neal Norwitzfc76d632006-01-10 06:03:13 +00001972- Patch #1400181, fix unicode string formatting to not use the locale.
1973 This is how string objects work. u'%f' could use , instead of .
1974 for the decimal point. Now both strings and unicode always use periods.
1975
Neal Norwitz671b9e32006-01-09 07:07:12 +00001976- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1977 configure would break checking curses.h.
1978
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001979- Bug #959576: The pwd module is now builtin. This allows Python to be
1980 built on UNIX platforms without $HOME set.
1981
Neal Norwitzc10978f2005-12-19 06:07:16 +00001982- Bug #1072182, fix some potential problems if characters are signed.
1983
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001984- Bug #889500, fix line number on SyntaxWarning for global declarations.
1985
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001986- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1987
Neal Norwitze7214a12005-12-18 05:03:17 +00001988- Support for converting hex strings to floats no longer works.
1989 This was not portable. float('0x3') now raises a ValueError.
1990
Barry Warsaw2a38a862005-12-18 01:27:35 +00001991- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001992 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001993 is now displayed in interactive prompt banner.
1994
Georg Brandlfa166682005-12-17 21:45:17 +00001995- Implementation of PEP 341 - Unification of try/except and try/finally.
1996 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001997 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001998
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001999- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2000 now encodes backslash correctly.
2001
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002002- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2003
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002004- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002005 and long longs.
2006
Neal Norwitz67715f02005-11-09 06:59:35 +00002007- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002008 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002009 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002010
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002011- Replaced most Unicode charmap codecs with new ones using the
2012 new Unicode translate string feature in the builtin charmap
2013 codec; the codecs were created from the mapping tables available
2014 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2015 encodings now include a mapping for the Apple logo)
2016
Tim Peterse3547fd2005-12-16 23:13:57 +00002017- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002018
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002019- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002020
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002021- A new AST parser implementation was completed. The abstract
2022 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002023 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002024
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002025- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002026 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2027
Neal Norwitz708e51a2005-10-03 04:48:15 +00002028- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2029
Neal Norwitz11bd1192005-10-03 00:54:56 +00002030- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2031 Provide a warning when a directory is passed on the command line.
2032

2034
2035- SF bug #772896: unknown encoding results in MemoryError.
2036
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002037- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002038 supported a __len__() method which evaluated to False when the iterator
2039 was empty.
2040
Guido van Rossum630db602005-09-20 18:49:54 +00002041- On 64-bit platforms, when __len__() returns a value that cannot be
2042 represented as a C int, raise OverflowError.
2043
Skip Montanarof8948ca2005-09-19 03:54:46 +00002044- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002045 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002046
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002047- SF bug #893549: parsing keyword arguments was broken with a few format
2048 codes.
2049
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002050- Changes donated by Elemental Security to make it work on AIX 5.3
2051 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2052 bug #105470: test_pwd fails on 64bit system (Opteron).
2053
Guido van Rossum539c6622005-09-14 17:49:54 +00002054- Changes donated by Elemental Security to make it work on HP-UX 11 on
2055 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2056
Georg Brandl4550b8d2005-08-26 06:43:52 +00002057- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002058 (fixes bug #1119418).
2059
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002060- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2061
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002062- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2063 exceptions that cause a function to exit.
2064
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002065- The implementation of set() and frozenset() was revised to use its
2066 own internal data structure. Memory consumption is reduced by 1/3
2067 and there are modest speed-ups as well. The API is unchanged.
2068
Tim Petersde7990b2005-07-17 23:45:23 +00002069- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2070
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002071- SF bug #1229429: PyObject_CallMethod failed to decrement some
2072 reference counts in some error exit cases.
2073
Tim Petersecc6e6a2005-07-10 22:30:55 +00002074- SF bug #1185883: Python's small-object memory allocator took over
2075 a block managed by the platform C library whenever a realloc specified
2076 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002077 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002078 portable way to copy data from the C-managed block into Python's
2079 small-object space without risking a memory fault. Python's small-object
2080 realloc now leaves such blocks under the control of the platform C
2081 realloc.
2082
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002083- SF bug #1232517: An overflow error was not detected properly when
2084 attempting to convert a large float to an int in os.utime().
2085
Raymond Hettinger3296e692005-06-29 23:29:56 +00002086- SF bug #1224347: hex longs now print with lowercase letters just
2087 like their int counterparts.
2088
Michael W. Hudson188d4362005-06-20 16:52:57 +00002089- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2090 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2091 interpreter states; back out that fix and do a better job (see
2092 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2093 for a longer write-up of the problem).
2094
Michael W. Hudsondf888462005-06-03 14:41:55 +00002095- SF patch #1180995: marshal now uses a binary format by default when
2096 serializing floats.
2097
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002098- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2099 the routines that promise to produce IEEE 754 binary representations
2100 of floats now simply copy bytes around.
2101
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002102- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2103 278.
2104
Brett Cannonc3647ac2005-04-26 03:45:26 +00002105- patch #1109424: int, long, float, complex, and unicode now check for the
2106 proper magic slot for type conversions when subclassed. Previously the
2107 magic slot was ignored during conversion. Semantics now match the way
2108 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002109 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002110 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002111 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002112
Barry Warsawc8d907c2005-04-19 23:43:40 +00002113- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2114 NULL, now raise an AttributeError when attempting to set or delete the
2115 attribute. Previously a TypeError was raised, but this was inconsistent
2116 with the equivalent pure-Python implementation.
2117
Michael W. Hudson774479c2005-04-18 08:46:17 +00002118- It is now safe to call PyGILState_Release() before
2119 PyEval_InitThreads() (note that if there is reason to believe there
2120 are multiple threads around you still must call PyEval_InitThreads()
2121 before using the Python API; this fix is for extension modules that
2122 have no way of knowing if Python is multi-threaded yet).
2123
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002124- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2125 disabled caused a crash.
2126
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002127- Bug #1165306: instancemethod_new allowed the creation of a method
2128 with im_class == im_self == NULL, which caused a crash when called.
2129
Tim Petersecc6e6a2005-07-10 22:30:55 +00002130- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002131 fixes the crash seen in bug #1165761
2132
Raymond Hettinger96229b12005-03-11 06:49:40 +00002133- Added two new builtins, any() and all().
2134
Brett Cannon409d8f22005-03-05 06:47:57 +00002135- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002136 (e.g., ``class C(): pass`` is no longer a syntax error).
2137 Patch #1176012 added support to the 'parser' module and 'compiler' package
2138 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002139
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002140- Patch #1115086: Support PY_LONGLONG in structmember.
2141
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002142- Bug #1155938: new style classes did not check that __init__() was
2143 returning None.
2144
Tim Petersecc6e6a2005-07-10 22:30:55 +00002145- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002146 ('\') with a specific error message.
2147
Martin v. Löwisff232d72005-03-03 09:24:38 +00002148- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2149
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002150- Bug #1124295: the __name__ attribute of file objects was
2151 inadvertently made inaccessible in restricted mode.
2152
Tim Petersecc6e6a2005-07-10 22:30:55 +00002153- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002154 an ferror() call.
2155
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002156- min() and max() now support key= arguments with the same meaning as in
2157 list.sort().
2158
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002159- The peephole optimizer now performs simple constant folding in expressions:
2160 (2+3) --> (5).
2161
Raymond Hettingera422c342005-01-11 03:03:27 +00002162- set and frozenset objects can now be marshalled. SF #1098985.
2163
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002164- Bug #1077106: Poor argument checking could cause memory corruption
2165 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002166
Jeremy Hyltonab630502005-02-04 18:44:06 +00002167- The parser did not complain about future statements in illegal
2168 positions. It once again reports a syntax error if a future
2169 statement occurs after anything other than a doc string.
2170
Neil Schemenauercf52c072005-08-12 17:34:58 +00002171- Change the %s format specifier for str objects so that it returns a
2172 unicode instance if the argument is not an instance of basestring and
2173 calling __str__ on the argument returns a unicode instance.
2174
Tim Petersf4e69282006-02-27 17:15:31 +00002175- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2176 current thread state when the auto-GIL-state machinery knows about
2177 it (since the thread state is being deleted, continuing to remember it
2178 can't help, but can hurt if another thread happens to get created with
2179 the same thread id).
2180
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002181Extension Modules

2198
2199- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2200
2201- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002202 is deprecated. The undocumented re.engine variable no longer exists.
2203

2206
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002207- The unicodedata module was updated to the 4.1 version of the Unicode
2208 database. The 3.2 version is still available as unicodedata.db_3_2_0
2209 for applications that require this specific version (such as IDNA).
2210
Neal Norwitzb62c4332006-03-04 18:35:47 +00002211- The timing module is no longer built by default. It was deprecated
2212 in PEP 4 in Python 2.0 or earlier.
2213
Guido van Rossum1968ad32006-02-25 22:38:04 +00002214- Patch 1433928: Added a new type, defaultdict, to the collections module.
2215 This uses the new __missing__ hook behavior added to dict (see above).
2216
Georg Brandldbd83392006-02-20 09:42:33 +00002217- Bug #854823: socketmodule now builds on Sun platforms even when
2218 INET_ADDRSTRLEN is not defined.
2219
Georg Brandlf4f44152006-02-18 22:29:33 +00002220- Patch #1393157: os.startfile() now has an optional argument to specify
2221 a "command verb" to invoke on the file.
2222
Neal Norwitz082b2df2006-02-07 07:04:46 +00002223- Bug #876637, prevent stack corruption when socket descriptor

2225
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002226- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2227 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.

2231 than the system default domain.
2232
Martin v. Löwis14694662006-02-03 12:54:16 +00002233- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2234 are reported, the limit on path name lengths is removed, and stat reports
2235 WindowsError now (instead of OSError).
2236
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002237- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2312 the request code argument, which results in more C-like behaviour
2313 for large or negative values.
2314
Tim Petersecc6e6a2005-07-10 22:30:55 +00002315- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002371- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2372 been renamed to have only a single underscore prefix. This was done to
2373 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002374
Nick Coghlan43832302006-04-23 17:04:07 +00002375- PEP 338: new module runpy defines a run_module function to support
2376 executing modules which provide access to source code or a code object
2377 via the PEP 302 import mechanisms.
2378
Anthony Baxter93f5b932006-04-03 08:05:07 +00002379- The email module's parsedate_tz function now sets the daylight savings

2387 in attribute values.
2388
Anthony Baxterc51ee692006-04-01 00:57:31 +00002389- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002390 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002391 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002392 module will not be built.
2393
Tim Petersc17976e2006-04-01 00:26:53 +00002394- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2395 aren't officially supported here, and trying to use them will probably
2396 raise an exception some day. But dicts have been allowed, and "mostly
2397 worked", so support for them won't go away without warning.
2398
Georg Brandl338ef7d2006-03-31 18:42:16 +00002399- Bug #1445068: getpass.getpass() can now be given an explicit stream
2400 argument to specify where to write the prompt.
2401

2411 to make it easier to monitor when daemon threads have completed
2412 processing all enqueued tasks. Patch #1455676.
2413

2417
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002418- email 4.0 package now integrated. This is largely the same as the email 3.0
2419 package that was included in Python 2.3, except that PEP 8 module names are
2420 now used (e.g. mail.message instead of email.Message). The MIME classes
2421 have been moved to a subpackage (e.g. email.mime.text instead of
2422 email.MIMEText). The old names are still supported for now. Several
2423 deprecated Message methods have been removed and lots of bugs have been
2424 fixed. More details can be found in the email package documentation.
2425
Walter Dörwald40108c92006-03-27 08:15:44 +00002426- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2427 (a subclass of tuple) that provides incremental decoders and encoders
2428 (a way to use stateful codecs without the stream API). Python functions
2429 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2430 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2431 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002432
Walter Dörwald067db482006-03-15 22:17:27 +00002433- Patch #1359365: Calling next() on a closed StringIO.String object raises
2434 a ValueError instead of a StopIteration now (like file and cString.String do).
2435 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2436 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002437
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002438- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002510 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2511 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2512 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2513 Ronald L. Rivest offered this advice for Python:
2514
2515 "The consensus of researchers in this area (at least as
2516 expressed at the NIST Hash Function Workshop 10/31/05),
2517 is that SHA-256 is a good choice for the time being, but
2518 that research should continue, and other alternatives may
2519 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002520
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002521- Added a subset of Fredrik Lundh's ElementTree package. Available

2583
Guido van Rossum755149f2005-07-27 00:00:44 +00002584- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2585 __hasattr__ and __delattr__ methods on class Tk that were breaking
2586 Tkdnd.
2587
Georg Brandl5dbda752005-07-17 20:27:41 +00002588- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2589 docstrings to either "article number" or "message id".
2590
Georg Brandla4a8b822005-07-15 09:13:21 +00002591- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2592 parameter, but uses the usual "kwargs=None".
2593
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002594- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002595 Patch #1209527 (Contributed by Connelly).
2596
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002597- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2598 to W3C name (404 -> 'Not Found'). RFE #1216944.
2599
Georg Brandl9e43acf2005-07-04 17:16:07 +00002600- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2601 as this can cause problems with apps closing all file descriptors.
2602
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002603- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002604 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002605
Georg Brandl2f210b62005-06-26 22:09:06 +00002606- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2607
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002608- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2609 error messages.
2610
Georg Brandl379f99d2005-06-26 21:09:38 +00002611- Bug #1108948: Cookie.py produced invalid JavaScript code.
2612
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002613- The tokenize module now detects and reports indentation errors.
2614 Bug #1224621.
2615
Raymond Hettinger68c04532005-06-10 11:05:19 +00002616- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002617 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002618 the generate_tokens() function now accepts a callable argument that
2619 terminates by raising StopIteration.
2620
Georg Brandl9166e1a2005-06-04 09:20:03 +00002621- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2622
Georg Brandl268e61c2005-06-03 14:28:50 +00002623- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2624 component of the path.
2625
Skip Montanaro174dd222005-05-14 20:54:16 +00002626- Patch #1120353: The xmlrpclib module provides better, more transparent,
2627 support for datetime.{datetime,date,time} objects. With use_datetime set
2628 to True, applications shouldn't have to fiddle with the DateTime wrapper
2629 class at all.
2630
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002631- distutils.commands.upload was added to support uploading distribution
2632 files to PyPI.
2633
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002634- distutils.commands.register now encodes the data as UTF-8 before posting
2635 them to PyPI.
2636
Raymond Hettinger267b8682005-03-27 10:47:39 +00002637- decimal operator and comparison methods now return NotImplemented
2638 instead of raising a TypeError when interacting with other types. This
2639 allows other classes to implement __radd__ style methods and have them
2640 work as expected.
2641
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002642- Bug #1163325: Decimal infinities failed to hash. Attempting to
2643 hash a NaN raised an InvalidOperation instead of a TypeError.
2644
Tim Petersecc6e6a2005-07-10 22:30:55 +00002645- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002646 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2647

2679
Guido van Rossumd0641422005-02-03 15:01:24 +00002680- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2681 disables recursive traversal through instance attributes, which can
2682 be exploited in various ways.
2683
Tim Peterse3547fd2005-12-16 23:13:57 +00002684- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002685 flags on the HTTP listening socket.
2686
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002687- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2688 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2689
Fred Drakefbdeaad2006-07-29 16:56:15 +00002690- Patches #893642, #1039083: add allow_none, encoding arguments to
2691 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002692
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002693- Bug #1110478: Revert os.environ.update to do putenv again.
2694
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002695- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2696
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002697- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2698
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002699- Enhancements to the csv module:
2700
2701 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002702 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002703 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002704 + Dialect parameter parsing has been re-implemented to improve error
2705 reporting.
2706 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2707 dictates.
2708 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002709 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002710 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002711 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2712 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002713 + reader now allows \r characters to be quoted (previously it only allowed
2714 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002715 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002716 + Dialect classes passed to the module are no longer instantiated by
2717 the module before being parsed (the former validation scheme required
2718 this, but the mechanism was unreliable).
2719 + The dialect registry now contains instances of the internal
2720 C-coded dialect type, rather than references to python objects.
2721 + the internal c-coded dialect type is now immutable.
2722 + register_dialect now accepts the same keyword dialect specifications
2723 as the reader and writer, allowing the user to register dialects
2724 without first creating a dialect class.
2725 + a configurable limit to the size of parsed fields has been added -
2726 previously, an unmatched quote character could result in the entire
2727 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002728 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002729 the parser field size limit (returning the former limit). The initial
2730 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002731 + A line_num attribute has been added to the reader object, which tracks
2732 the number of lines read from the source iterator. This is not
2733 the same as the number of records returned, as records can span
2734 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002735 + reader and writer objects were not being registered with the cyclic-GC.
2736 This has been fixed.
2737
Brett Cannone6539c42005-01-08 02:43:53 +00002738- _DummyThread objects in the threading module now delete self.__block that is
2739 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2740 lock primitives tend to be limited in number and thus should not be wasted on
2741 a _DummyThread object. Fixes bug #1089632.
2742
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002743- The imghdr module now detects Exif files.
2744
Raymond Hettinger6065d322004-12-20 23:51:53 +00002745- StringIO.truncate() now correctly adjusts the size attribute.
2746 (Bug #951915).
2747
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002748- locale.py now uses an updated locale alias table (built using
2749 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2750 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002751 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002752
Raymond Hettinger3557f422004-12-07 12:02:02 +00002753- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2754
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002755- the pickle module no longer accepts the deprecated None option in the
2756 args tuple returned by __reduce__().
2757
Brett Cannon84667c02004-12-07 03:25:18 +00002758- optparse now optionally imports gettext. This allows its use in setup.py.
2759
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002760- the pickle module no longer uses the deprecated bin parameter.
2761
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002762- the shelve module no longer uses the deprecated binary parameter.
2763
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002764- the pstats module no longer uses the deprecated ignore() method.
2765
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002766- the filecmp module no longer uses the deprecated use_statcache argument.
2767
Raymond Hettinger664347b2004-12-04 21:21:53 +00002768- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2769 extended or overridden by subclasses. Formerly, the subclassed method would
2770 be ignored by the rest of the module. (Bug #1078905).
2771
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002772- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002773 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002774
Walter Dörwald36733692004-12-22 12:50:50 +00002775- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2776 once when a size argument is given. This prevents a buffer overflow in the
2777 tokenizer with very long source lines.
2778
Barry Warsaw538561e2006-01-01 21:48:54 +00002779- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2780 immediately after creating the object, without any intervening
2781 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002782
Skip Montanaro05885812005-01-16 20:48:27 +00002783- The reconvert.quote function can now emit triple-quoted strings. The
2784 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002785
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002786- ``UserString.MutableString`` now supports negative indices in
2787 ``__setitem__`` and ``__delitem__``
2788
Greg Ward40407942005-03-05 02:53:17 +00002789- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2790 correctly.
2791
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002792- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2793 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2794 character even if the user has passed a size parameter to get a proper
2795 line ending. Remove the special handling of a "\r\n" that has been split
2796 between two lines.
2797
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002798- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2799 about illegal code points. The codec now supports PEP 293 style error
2800 handlers.
2801
Walter Dörwald78a78b02005-09-01 12:04:29 +00002802- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002803 from the input stream, so that the output is a byte string in the correct
2804 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002805
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002806- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2807 considering it exactly like a '*'.
2808
Walter Dörwald007f8df2005-10-09 19:42:27 +00002809- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2810 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002811
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002812- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2813
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002814- Patch #1413711: Certain patterns of differences were making difflib
2815 touch the recursion limit.
2816
Walter Dörwald58917a62006-03-31 15:26:22 +00002817- Bug #947906: An object oriented interface has been added to the calendar
2818 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002819 called as a script (e.g. via ``python -mcalendar``). Localized month and
2820 weekday names can be ouput (even if an exotic encoding is used) using
2821 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002822

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002837- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2838 The zlib module is now builtin on Windows.
2839
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002840- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2841
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002842- Bug #1189330: configure did not correctly determine the necessary
2843 value of LINKCC if python was built with GCC 4.0.
2844
Trent Mick8321b422005-07-26 02:29:21 +00002845- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2846 vulnerability in zlib 1.2.1 and 1.2.2.
2847
Brett Cannon08cd5982005-04-24 22:26:38 +00002848- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2849 flags that change binary compatibility. Changes were also made to
2850 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002851 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002852
Bob Ippolitoed233462005-03-29 13:47:59 +00002853- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2854 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2855 no longer exists). This configure patch makes things right.
2856
Martin v. Löwise2713be2005-03-08 15:03:08 +00002857- Bug #1158607: Build with --disable-unicode again.
2858
Brett Cannon46d96232005-02-16 00:07:19 +00002859- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2860 defined. Discovered as a result of not being able to build on OS X.
2861
Brett Cannon516592f2004-12-07 00:42:59 +00002862- setup.py now uses the directories specified in LDFLAGS using the -L option
2863 and in CPPFLAGS using the -I option for adding library and include
2864 directories, respectively, for compiling extension modules against. This has
2865 led to the core being compiled using the values in CPPFLAGS. It also removes
2866 the need for the special-casing of both DarwinPorts and Fink for darwin since
2867 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2868 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2869 Fink, ``-I/opt/local/include`` for DarwinPorts).
2870
Brett Cannon43802422005-02-10 20:48:03 +00002871- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2872 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2873 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2874 Closes bug #1096244. Thanks Gregory Bond.

2877-----
2878
Tim Petersc9d78aa2006-03-26 23:27:58 +00002879- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2880 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2881 is obtained via the ``PyObject_`` family, it must be released via the
2882 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2883 always been officially true, but when Python's small-object allocator was
2884 introduced, an attempt was made to cater to a few extension modules
2885 discovered at the time that obtained memory via ``PyObject_New`` but
2886 released it via ``PyMem_DEL``. It's years later, and if such code still
2887 exists it will fail now (probably with segfaults, but calling wrong
2888 low-level memory management functions can yield many symptoms).
2889
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002890- Added a C API for set and frozenset objects.
2891
Raymond Hettinger66517482004-12-03 11:45:13 +00002892- Removed PyRange_New().
2893
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002894- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2895 mapping argument now. This string is used as a mapping table. Byte values
2896 greater than the length of the string and 0xFFFE are treated as undefined
2897 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002905- Patch #1276356: New resource "urlfetch" is implemented. This enables
2906 even impatient people to run tests that require remote files.
