634-----------------
635
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000636- Make _PyGILState_NoteThreadState() static, it was not used anywhere
637 outside of pystate.c and should not be necessary.
638
Brett Cannon19d76c52006-09-09 07:18:44 +0000639- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
640 allows calling unicode() on exceptions classes directly to succeed.
641
Georg Brandlecab6232006-09-06 06:47:02 +0000642- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000657- The return tuple from str.rpartition(sep) is (tail, sep, head) where
658 head is the original string if sep was not found.
659
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000660- Bug #1520864: unpacking singleton tuples in list comprehensions and
661 generator expressions (x for x, in ... ) works again. Fixing this problem
662 required changing the .pyc magic number. This means that .pyc files
663 generated before 2.5c2 will be regenerated.

775Core and builtins
776-----------------
777
Neal Norwitz24b6f202006-09-05 04:43:56 +0000778- Fix infinite recursion when subclassing long and overriding __hash__.
779
780- Fix concatenation (+=) of long strings.
781
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000782- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000783 compared equal or unequal to a string and a UnicodeDecodeError
784 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000785
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000786 Instead, the equal (==) and unequal (!=) comparison operators will
787 now issue a UnicodeWarning and interpret the two objects as
788 unequal. The UnicodeWarning can be filtered as desired using
789 the warning framework, e.g. silenced completely, turned into an
790 exception, logged, etc.
791
792 Note that compare operators other than equal and unequal will still
793 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000794
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000795- Fix segfault when doing string formatting on subclasses of long.
796
797- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
798 with new-style classes.
799
800- Fix bug related to __len__ functions returning negative values with
801 classic classes.
802
803- Patch #1538606, Fix __index__() clipping. There were some problems
804 discovered with the API and how integers that didn't fit into Py_ssize_t
805 were handled. This patch attempts to provide enough alternatives
806 to effectively use __index__.
807
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000808- Bug #1536021: __hash__ may now return long int; the final hash
809 value is obtained by invoking hash on the long int.
810
Thomas Hellerab1049c2006-08-08 17:37:00 +0000811- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000813- Bug #1535165: fixed a segfault in input() and raw_input() when
814 sys.stdin is closed.
815
Thomas Heller74d36f02006-08-04 18:17:40 +0000816- On Windows, the PyErr_Warn function is now exported from
817 the Python dll again.
818
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000819- Bug #1191458: tracing over for loops now produces a line event
820 on each iteration. Fixing this problem required changing the .pyc
821 magic number. This means that .pyc files generated before 2.5c1
822 will be regenerated.
823
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000824- Bug #1333982: string/number constants were inappropriately stored
825 in the byte code and co_consts even if they were not used, ie
826 immediately popped off the stack.
827
Georg Brandle9462c72006-08-04 18:03:37 +0000828- Fixed a reference-counting problem in property().

831Library
832-------
833
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000834- Fix a bug in the ``compiler`` package that caused invalid code to be
835 generated for generator expressions.
836
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000837- The distutils version has been changed to 2.5.0. The change to
838 keep it programmatically in sync with the Python version running
839 the code (introduced in 2.5b3) has been reverted. It will continue
840 to be maintained manually as static string literal.
841
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000842- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000843 and this cannot be converted to the required C type, an exception is
844 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000845 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000846
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000847- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000848 an exception.
849
Tim Peterscbdd3502006-09-05 01:47:53 +0000850- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000851 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000852 workarounds for clocks with low resolution, to stop the code yielding
853 duplicate UUIDs.
854
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000855- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
856 before raising SystemExit, allowing IDLE to honor quit() and exit().
857
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000858- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
859
Georg Brandl7a1af772006-08-14 21:55:28 +0000860- Patch #1536071: trace.py should now find the full module name of a
861 file correctly even on Windows.
862
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000863- logging's atexit hook now runs even if the rest of the module has
864 already been cleaned up.

884
Thomas Heller1ce433e2006-08-14 16:20:04 +0000885- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
886 '-no-stack-protector' compiler flag for OpenBSD has been removed.
887
Thomas Heller86720042006-08-14 11:17:48 +0000888- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now

944Core and builtins
945-----------------
946
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000947- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000948 returned a long (see PEP 353).
949
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000950- Bug #1515471: string.replace() accepts character buffers again.
951
Neal Norwitz07aadb12006-07-30 06:55:48 +0000952- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
953 This provides the proper warning for struct.pack().
954 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
955
Neal Norwitz0d62a062006-07-30 06:53:31 +0000956- Patch #1531113: Fix augmented assignment with yield expressions.
957 Also fix a SystemError when trying to assign to yield expressions.
958
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000959- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
960 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
961 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
962 excessive filesystem operations during imports.
963
Tim Petersbc24eee2006-07-27 01:14:53 +0000964- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
965 operations on signed longs that are formally undefined by C.
966 Unfortunately, at least one compiler now cares about that, so complicated
967 the code to make that compiler happy again.
968
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000969- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
970
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000971- Patch #1232023: Stop including current directory in search
972 path on Windows.
973
Neal Norwitze1fdb322006-07-21 05:32:28 +0000974- Fix some potential crashes found with failmalloc.
975
Neal Norwitze7563102006-07-17 01:00:16 +0000976- Fix warnings reported by Klocwork's static analysis tool.
977
Neal Norwitz84be93b2006-07-16 01:50:38 +0000978- Bug #1512814, Fix incorrect lineno's when code within a function
979 had more than 255 blank lines.
980
Georg Brandl9dceedb2006-07-12 15:31:17 +0000981- Patch #1521179: Python now accepts the standard options ``--help`` and
982 ``--version`` as well as ``/?`` on Windows.
983
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000984- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000985 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000986 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000987
Tim Peters112aad32006-07-19 00:03:19 +0000988- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000989 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000990 new ``sys._current_frames()`` returns a dictionary with one entry,
991 mapping the faux "thread id" 0 to the current frame.
992
Ronald Oussoren3075e162006-07-25 20:28:55 +0000993- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

998
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000999- Correction of patch #1455898: In the mbcs decoder, set final=False
1000 for stream decoder, but final=True for the decode function.
1001
Georg Brandl07fec3a2006-08-01 18:49:24 +00001002- os.urandom no longer masks unrelated exceptions like SystemExit or
1003 KeyboardInterrupt.
1004
Tim Peters4643c2f2006-08-10 22:45:34 +00001005- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001006 shutil.copytree on Windows
1007
Georg Brandle34ac7c2006-07-30 11:07:23 +00001008- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1009 refers to file descriptors, not file objects.
1010
Tim Peterscbdd3502006-09-05 01:47:53 +00001011- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001012 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001013 #1513611, and probably others.
1014
Georg Brandledd9b0d2006-07-29 09:33:26 +00001015- Bug #1441397: The compiler module now recognizes module and function
1016 docstrings correctly as it did in Python 2.4.
1017
Tim Peters6f681472006-07-27 23:44:37 +00001018- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1019 lost that tests are sorted by name before being run. This rarely
1020 matters for well-written tests, but can create baffling symptoms if
1021 side effects from one test to the next affect outcomes. ``DocTestFinder``
1022 has been changed to sort the list of tests it returns.
1023
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001024- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001025 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001026
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001027- Bug #978833: Really close underlying socket in _socketobject.close.
1028
Georg Brandldb232dc2006-08-20 13:15:43 +00001029- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1030 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001031
Georg Brandlcf0c1722006-07-26 07:23:32 +00001032- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1033 to recursive calls and call it with the failing package name.
1034
Martin v. Löwis0b483032006-07-25 09:53:12 +00001035- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1036
Georg Brandlc13c34c2006-07-24 14:09:56 +00001037- Patch #1515343: Fix printing of deprecated string exceptions with a
1038 value in the traceback module.
1039
Greg Ward48fae7a2006-07-23 16:05:51 +00001040- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1041
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001042- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1043
Brett Cannoncaebe222006-07-18 04:41:36 +00001044- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1045 argument tuple. For arguments where zero is illegal, the value is forced to
1046 the minimum value that is correct. This is to support an undocumented but
1047 common way people used to fill in inconsequential information in the time
1048 tuple pre-2.4.
1049
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001050- Patch #1220874: Update the binhex module for Mach-O.
1051
Barry Warsawb110bad2006-07-21 14:51:07 +00001052- The email package has improved RFC 2231 support, specifically for
1053 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1054 (name*0=<blah>) parameter continuations. This may change the types of
1055 values returned from email.message.Message.get_param() and friends.
1056 Specifically in some cases where non-encoded continuations were used,
1057 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1058 will just return the string (since non-encoded continuations don't have
1059 charset and language parts).
1060
1061 Also, whereas % values were decoded in all parameter continuations, they are
1062 now only decoded in encoded parameter parts.
1063
Ronald Oussoren3075e162006-07-25 20:28:55 +00001064- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1065
1066- Bug #1517996: IDLE now longer shows the default Tk menu when a
1067 path browser, class browser or debugger is the frontmost window on MacOS X
1068
Barry Warsaw00decd72006-07-27 23:43:15 +00001069- Patch #1520294: Support for getset and member descriptors in types.py,
1070 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1071 of an object against these built-in types and more importantly, for getting
1072 their docstrings printed in the interactive interpreter's help() function.

1076-----------------
1077
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001078- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1079 a socket operation on a socket with a timeout, the exception will be
1080 caught correctly. Previously, the exception was not caught.
1081
Thomas Heller1393d6a2006-07-28 21:43:20 +00001082- Patch #1529514: The _ctypes extension is now compiled on more
1083 openbsd target platforms.
1084
Tim Peters9cab5932006-07-28 00:30:00 +00001085- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1086 a memory leak, affecting pickles and deep copies.
1087
Tim Petersbc24eee2006-07-27 01:14:53 +00001088- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1090
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001091- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1092
Thomas Hellerce049a02006-07-14 17:51:14 +00001093- Patch #1521817: Index range checking on ctypes arrays containing
1094 exactly one element enabled again. This allows iterating over these
1095 arrays, without the need to check the array size before.
1096
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001097- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001098 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001099 /dev/null in certain cases; this is now fixed.
1100
Thomas Heller47d7a062006-07-12 08:43:47 +00001101- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1102 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001103
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001104- Because of a misspelled preprocessor symbol, ctypes was always
1105 compiled without thread support; this is now fixed.
1106
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001107- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1108 methods now allow their database parameter to be None as the
1109 sleepycat API allows.
1110
Matt Flemingec926502006-07-28 11:27:27 +00001111- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1112 bluetooth API compared with Linux and FreeBSD.

1116
1117- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1118 how long the test file should take to play. Now accepts taking 2.93 secs
1119 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1120
Georg Brandl4793aa32006-07-28 18:31:39 +00001121- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1122 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1123 run via ``regrtest.py``. Now they do.

1133- PythonLauncher now works correctly when the path to the script contains
1134 characters that are treated specially by the shell (such as quotes).
1135
1136- Bug #1527397: PythonLauncher now launches scripts with the working directory
1137 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001138 directory. That latter was an implementation accident and not what users

1152
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001153- Bug #1501934: The scope of global variables that are locally assigned
1154 using augmented assignment is now correctly determined.
1155
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001156- Bug #927248: Recursive method-wrapper objects can now safely

Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001162- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to

1167
Neal Norwitz28746ab2006-07-09 22:14:42 +00001168- On 64 bit systems, int literals that use less than 64 bits are

1170
Neal Norwitzed657552006-07-10 00:04:44 +00001171- Bug #1512814, Fix incorrect lineno's when code at module scope

1173
Tim Peters32a83612006-07-10 21:08:24 +00001174- New function ``sys._current_frames()`` returns a dict mapping thread
1175 id to topmost thread stack frame. This is for expert use, and is
1176 especially useful for debugging application deadlocks. The functionality
1177 was previously available in Fazal Majid's ``threadframe`` extension
1178 module, but it wasn't possible to do this in a wholly threadsafe way from
1179 an extension.

1188
Tim Peters32a83612006-07-10 21:08:24 +00001189- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001190 environment variable to be set in order to the SDK environment
1191 for finding the compiler, include files, etc.
1192
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001193- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1194
Nick Coghlan2d792252006-07-06 13:47:18 +00001195- warnings.py now ignores ImportWarning by default
1196
Thomas Woutersadd19112006-07-05 11:03:49 +00001197- string.Template() now correctly handles tuple-values. Previously,
1198 multi-value tuples would raise an exception and single-value tuples would
1199 be treated as the value they contain, instead.
1200
Martin v. Löwisede77f52006-07-03 13:01:35 +00001201- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1202 even if some data are received.
1203
Martin v. Löwis45482392006-07-03 12:28:58 +00001204- Bug #1267547: Put proper recursive setup.py call into the
1205 spec file generated by bdist_rpm.

1208 degrees and radians.
1209
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001210- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001211 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001212
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001213- Bug #1514703: Only setup canvas window in turtle when the canvas
1214 is created.
1215
Martin v. Löwis7596e832006-07-01 15:33:37 +00001216- Bug #1513223: .close() of a _socketobj now releases the underlying

1218
Fred Drake10497c82006-06-29 02:57:48 +00001219- Bug #1504333: Make sgmllib support angle brackets in quoted
1220 attribute values.
1221
1222- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1223 sgmllib ('[' and ']' were not accepted).
1224
Georg Brandl1be63af2006-06-28 20:23:25 +00001225- Fix a bug in the turtle module's end_fill function.
1226
Brett Cannon53ab5b72006-06-22 16:49:14 +00001227- Bug #1510580: The 'warnings' module improperly required that a Warning
1228 category be either a types.ClassType and a subclass of Warning. The proper
1229 check is just that it is a subclass with Warning as the documentation states.
1230
Georg Brandlad29e632006-06-21 17:45:17 +00001231- The compiler module now correctly compiles the new try-except-finally
1232 statement (bug #1509132).
1233
Neal Norwitz60373cd2006-06-22 06:30:50 +00001234- The wsgiref package is now installed properly on Unix.
1235
Vinay Sajip28e57612006-07-01 10:45:20 +00001236- A bug was fixed in logging.config.fileConfig() which caused a crash on
1237 shutdown when fileConfig() was called multiple times.
1238
Gerhard Häring762fbd32006-07-02 17:48:30 +00001239- The sqlite3 module did cut off data from the SQLite database at the first
1240 null character before sending it to a custom converter. This has been fixed
1241 now.
1242
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001243Extension Modules
1244-----------------
1245
Tim Peters112aad32006-07-19 00:03:19 +00001246- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1247 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1248 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001249
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001250- Assigning None to pointer type fields in ctypes structures possible
1251 overwrote the wrong fields, this is fixed now.
1252
1253- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1254 on non-Windows platforms.
1255
1256- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1257 integer or long, without range checking.
1258
1259- Patch #1517790: It is now possible to use custom objects in the ctypes
1260 foreign function argtypes sequence as long as they provide a from_param
1261 method, no longer is it required that the object is a ctypes type.
1262
1263- The '_ctypes' extension module now works when Python is configured
1264 with the --without-threads option.
1265
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001266- Bug #1513646: os.access on Windows now correctly determines write
1267 access, again.
1268
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001269- Bug #1512695: cPickle.loads could crash if it was interrupted with
1270 a KeyboardInterrupt.
1271
Neal Norwitza12aa882006-07-06 06:45:08 +00001272- Bug #1296433: parsing XML with a non-default encoding and
1273 a CharacterDataHandler could crash the interpreter in pyexpat.
1274
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001275- Patch #1516912: improve Modules support for OpenVMS.
1276

1278-----
1279
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001280- Automate Windows build process for the Win64 SSL module.
1281
Tim Peters32a83612006-07-10 21:08:24 +00001282- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001283 Previously, the slight difference could cause compilation errors of the
1284 'zlib' module on systems with more than one version of zlib.
1285
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001286- The MSI compileall step was fixed to also support a TARGETDIR
1287 with spaces in it.
1288
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001289- Bug #1517388: sqlite3.dll is now installed on Windows independent
1290 of Tcl/Tk.
1291
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001292- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001293 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001295Tests
1296-----
1297
1298- Call os.waitpid() at the end of tests that spawn child processes in order
1299 to minimize resources (zombies).
1300
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001301Documentation
1302-------------
1303
Nick Coghlan2d792252006-07-06 13:47:18 +00001304- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1305 documentation for the warnings module.
1306
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001307- Patch #1509163: MS Toolkit Compiler no longer available.
1308
Neal Norwitz56640df2006-07-10 02:36:41 +00001309- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001316
1317Core and builtins
1318-----------------
1319
Georg Brandla56b9152006-06-19 06:35:54 +00001320- Patch #1507676: Error messages returned by invalid abstract object operations
1321 (such as iterating over an integer) have been improved and now include the
1322 type of the offending object to help with debugging.
1323
Brett Cannonea3912b2006-06-13 21:46:41 +00001324- Bug #992017: A classic class that defined a __coerce__() method that returned
1325 its arguments swapped would infinitely recurse and segfault the interpreter.
1326
Neal Norwitz909eb122006-06-12 02:13:21 +00001327- Fix the socket tests so they can be run concurrently.
1328
Neal Norwitzb9845e72006-06-12 02:11:18 +00001329- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001330 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001331
Brett Cannon22565aa2006-06-09 22:31:23 +00001332- Bug #532646: object.__call__() will continue looking for the __call__
1333 attribute on objects until one without one is found. This leads to recursion
1334 when you take a class and set its __call__ attribute to an instance of the
1335 class. Originally fixed for classic classes, but this fix is for new-style.
1336 Removes the infinite_rec_3 crasher.
1337
Georg Brandl24250812006-06-09 18:45:48 +00001338- The string and unicode methods startswith() and endswith() now accept
1339 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1340
Brett Cannonde3b0522006-06-08 17:00:45 +00001341- Buffer objects, at the C level, never used the char buffer
1342 implementation even when the char buffer for the wrapped object was
1343 explicitly requested (originally returned the read or write buffer).
1344 Now a TypeError is raised if the char buffer is not present but is
1345 requested.
1346
Georg Brandlddbaa662006-06-04 21:56:52 +00001347- Patch #1346214: Statements like "if 0: suite" are now again optimized
1348 away like they were in Python 2.4.
1349
Georg Brandlb7c8f542006-05-27 12:30:25 +00001350- Builtin exceptions are now full-blown new-style classes instead of
1351 instances pretending to be classes, which speeds up exception handling
1352 by about 80% in comparison to 2.5a2.
1353
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001354- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1355 Unicode 4.1.
1356
Georg Brandlf4ef1162006-05-26 18:03:31 +00001357- Patch #921466: sys.path_importer_cache is now used to cache valid and
1358 invalid file paths for the built-in import machinery which leads to
1359 fewer open calls on startup.
1360
Tim Peters696cf432006-05-24 21:10:40 +00001361- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1362 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1363 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1364 the number of input digits (it was and remains linear-time for bases
1365 2, 4, 8, 16 and 32).
1366
Tim Petersb713ec22006-05-23 18:45:30 +00001367- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1368 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1369 an integer close to ``sys.maxint``. This was repaired by patch
1370 #1335972, which also gives a nice speedup.
1371
Richard Jonescebbefc2006-05-23 18:28:17 +00001372- Patch #1337051: reduced size of frame objects.
1373
1374- PyErr_NewException now accepts a tuple of base classes as its
1375 "base" parameter.
1376
Richard Jones7c88dcc2006-05-23 10:37:38 +00001377- Patch #876206: function call speedup by retaining allocated frame
1378 objects.
1379
Georg Brandl7b90e162006-05-18 07:01:27 +00001380- Bug #1462152: file() now checks more thoroughly for invalid mode
1381 strings and removes a possible "U" before passing the mode to the
1382 C library function.
1383
Neal Norwitz1004a532006-05-15 07:17:23 +00001384- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1385
Neal Norwitz373f0a72006-05-15 07:04:36 +00001386- Bug #1487966: Fix SystemError with conditional expression in assignment
1387
Martin v. Löwis879768d2006-05-11 13:28:43 +00001388- WindowsError now has two error code attributes: errno, which carries
1389 the error values from errno.h, and winerror, which carries the error
1390 values from winerror.h. Previous versions put the winerror.h values
1391 (from GetLastError()) into the errno attribute.
1392
Martin v. Löwis77736712006-05-04 05:51:03 +00001393- Patch #1475845: Raise IndentationError for unexpected indent.
1394
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001395- Patch #1479181: split open() and file() from being aliases for each other.
1396
Tim Peters44bd9862006-06-01 13:49:23 +00001397- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1398 methods were always silently ignored by dictionaries when comparing keys.
1399 They are now passed through (except when using the C API function
1400 ``PyDict_GetItem()``, whose semantics did not change).
1401
1402- Bug #1456209: In some obscure cases it was possible for a class with a
1403 custom ``__eq__()`` method to confuse dict internals when class instances
1404 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1405 No, you don't have any code that did this ;-)

1409
Trent Mick960a3f82006-06-28 20:30:41 +00001410- Bug #1295808: expat symbols should be namespaced in pyexpat
1411
1412- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1413
Brett Cannon6ee7d012006-06-08 16:23:04 +00001414- Change binascii.hexlify to accept a read-only buffer instead of only a char
1415 buffer and actually follow its documentation.
1416
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001417- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1418
Nick Coghlanc649ec52006-05-29 12:43:05 +00001419- Patch #1478788 (modified version): The functional extension module has
1420 been renamed to _functools and a functools Python wrapper module added.
1421 This provides a home for additional function related utilities that are
1422 not specifically about functional programming. See PEP 309.
1423
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001424- Patch #1493701: performance enhancements for struct module.
1425
Georg Brandl378d5922006-05-17 14:26:50 +00001426- Patch #1490224: time.altzone is now set correctly on Cygwin.
1427
Georg Brandl8d3342b2006-05-16 07:38:27 +00001428- Patch #1435422: zlib's compress and decompress objects now have a
1429 copy() method.
1430
Andrew MacIntyre92913322006-06-13 15:04:24 +00001431- Patch #1454481: thread stack size is now tunable at runtime for thread
1432 enabled builds on Windows and systems with Posix threads support.
1433
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001434- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1435 (up to the system limit of 32K characters).
1436
1437- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1438 As a result, these functions now raise WindowsError instead of OSError.
1439
Tim Peters7a822da2006-05-25 21:50:17 +00001440- ``time.clock()`` on Win64 should use the high-performance Windows
1441 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1442 Windows platforms).
1443
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001444- Calling Tk_Init twice is refused if the first call failed as that
1445 may deadlock.
1446
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001447- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1448 accept it without potentially using an uninitialized pointer.
1449
1450- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1451 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1452 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001453
Gregory P. Smith372b5832006-06-05 18:48:21 +00001454- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001455 [pybsddb project SF patch number 1466734]
1456
Gregory P. Smith372b5832006-06-05 18:48:21 +00001457- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1458 parameter is supplied. [SF pybsddb bug #1477863]
1459
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001460- bsddb: the __len__ method of a DB object has been fixed to return correct
1461 results. It could previously incorrectly return 0 in some cases.
1462 Fixes SF bug 1493322 (pybsddb bug 1184012).
1463
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001464- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1465 aborts the db transaction safely when a modifier callback fails.
1466 Fixes SF python patch/bug #1408584.
1467
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001468- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001469 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001470 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry

1495 mime.types file for determining MIME types.
1496
Georg Brandl2605ca82006-06-14 06:08:31 +00001497- Bug #1339007: Shelf objects now don't raise an exception in their
1498 __del__ method when initialization failed.
1499
Martin v. Löwisd8251432006-06-14 05:21:04 +00001500- Patch #1455898: The MBCS codec now supports the incremental mode for
1501 double-byte encodings.
1502
Tim Peters43898b42006-06-14 04:09:25 +00001503- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1504 guarantee that adjacent triples in the return list always describe
1505 non-adjacent blocks. Previously, a pair of matching blocks could end
1506 up being described by multiple adjacent triples that formed a partition
1507 of the matching pair.
1508
Greg Ward0e0c9f42006-06-11 16:24:11 +00001509- Bug #1498146: fix optparse to handle Unicode strings in option help,

1511
Greg Wardd1c797e2006-06-11 14:42:41 +00001512- Bug #1366250: minor optparse documentation error.

1515 clarify docs.
1516
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001517- The wsgiref package has been added to the standard library.
1518
Nick Coghlan676725d2006-06-08 13:54:49 +00001519- The functions update_wrapper() and wraps() have been added to the functools
1520 module. These make it easier to copy relevant metadata from the original
1521 function when writing wrapper functions.
1522
Tim Petersd6a9eef2006-06-05 01:48:21 +00001523- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1524 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001525
Martin v. Löwis3f767792006-06-04 19:36:28 +00001526- Patch #1359618: Speed up charmap encoder by using a trie structure
1527 for lookup.
1528
Tim Petersd609b1a2006-06-02 23:22:51 +00001529- The functions in the ``pprint`` module now sort dictionaries by key
1530 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1531 if and only if its display required more than one line, although that
1532 wasn't documented. The new behavior increases predictability; e.g.,
1533 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1534
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001535- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1554
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001555- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1556 stdout arguments, making it possible to redirect input and output
1557 for remote debugging.
1558
1559- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1560 a couple of issues, notably handling of long file names using the
1561 GNU LONGNAME extension.
1562
1563- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1564 new flag when ``name`` is already the name of an option flag.
1565
1566- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1567 package.
1568
1569- Patch #1472854: make the rlcompleter.Completer class usable on non-
1570 UNIX platforms.

1610Core and builtins
1611-----------------
1612
Thomas Heller1b046642006-04-18 18:51:06 +00001613- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1614 by converting these apis from macros into exported functions again:
1615
1616 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1617 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1618 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1619 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1620 PyRun_String Py_CompileString
1621
Martin v. Löwis45294a92006-04-18 06:24:08 +00001622- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1623
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001624- All uses of PyStructSequence_InitType have been changed to initialize
1625 the type objects only once, even if the interpreter is initialized
1626 multiple times.
1627
Neal Norwitz61546162006-04-14 05:20:28 +00001628- Bug #1454485, array.array('u') could crash the interpreter. This was
1629 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1630 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1631
1632- Py_UNICODE is unsigned. It was always documented as unsigned, but
1633 due to a bug had a signed value in previous versions.
1634
Tim Peters3a5e8b12006-04-11 01:44:07 +00001635- Patch #837242: ``id()`` of any Python object always gives a positive
1636 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1637 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001638 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001639 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001640
Tim Peters3a5e8b12006-04-11 01:44:07 +00001641 def __hash__(self):
1642 return id(self) # WRONG
1643
1644 because a hash result must be a (short) Python int but it was always
1645 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001646 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001647 was always usable as a hash value before this patch. That's no longer
1648 necessarily so.
1649
1650- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001651 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001652 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001653 #1454844)
1654
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001655- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1656 involving generators that have paused outside of any ``try`` or ``with``
1657 blocks. (In 2.5a1, a paused generator that was part of a reference
1658 cycle could not be garbage collected, regardless of whether it was
1659 paused in a ``try`` or ``with`` block.)

1673 the cachesize parameter.
1674
1675- Bug #1149413: bsddb.*open() no longer raises an exception when using
1676 a temporary db (file=None) with the 'n' flag to truncate on open.

1678- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1679 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001680
Armin Rigoa9017c32006-04-19 11:50:27 +00001681- Patch #1062014: AF_UNIX sockets under Linux have a special

1689 abusing errno.
1690
Tim Peters711bf302006-04-25 03:31:36 +00001691- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1692 a doctest to be skipped (the code is not run, and the expected output
1693 or exception is ignored).
1694
Nick Coghlanda2268f2006-04-24 04:37:15 +00001695- Fixed contextlib.nested to cope with exceptions being raised and
1696 caught inside exit handlers.
1697
Greg Wardab05edc2006-04-23 03:47:58 +00001698- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1699 hex, octal, or binary; add ``append_const`` action; keep going if
1700 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1701 added ``epilog`` for better help generation).
1702
Tim Peters21fbd572006-04-21 21:18:10 +00001703- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1704 called from a thread spawned as a side effect of importing a module.
1705
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001706- The pydoc module now supports documenting packages contained in
1707 .zip or .egg files.
1708
1709- The pkgutil module now has several new utility functions, such
1710 as ``walk_packages()`` to support working with packages that are either
1711 in the filesystem or zip files.
1712
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001713- The mailbox module can now modify and delete messages from
1714 mailboxes, in addition to simply reading them. Thanks to Gregory
1715 K. Johnson for writing the code, and to the 2005 Google Summer of
1716 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001717
Tim Petersc7605f22006-04-17 21:12:33 +00001718- The ``__del__`` method of class ``local`` in module ``_threading_local``
1719 returned before accomplishing any of its intended cleanup.
1720
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001721- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001747- The Makefile now has a reindent target, which runs reindent.py on
1748 the library.
1749

1755 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001756 specified. (Can be overridden by explicitly setting LINKCC.) Decouple

1762
Tim Peters8931ff12006-05-13 23:28:20 +00001763- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1764 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

1766
Anthony Baxter51bcb682006-04-05 14:51:42 +00001767Tests
1768-----
1769
Nick Coghlanda2268f2006-04-24 04:37:15 +00001770- test_contextlib now checks contextlib.nested can cope with exceptions
1771 being raised and caught inside exit handlers.

1774
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001775- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1776 it separately and by hand. It also wasn't cleaning up its changes to
1777 the current Decimal context.
1778
Thomas Woutersabd08882006-04-26 15:53:30 +00001779- regrtest.py now has a -M option to run tests that test the new limits of
1780 containers, on 64-bit architectures. Running these tests is only sensible
1781 on 64-bit machines with more than two gigabytes of memory. The argument
1782 passed is the maximum amount of memory for the tests to use.

1791-------------
1792
Tim Petersb06d28c2006-05-12 01:57:59 +00001793- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1794
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001795- PEP 343: Added Context Types section to the library reference
1796 and attempted to bring other PEP 343 related documentation into
1797 line with the implementation and/or python-dev discussions.
1798
Tim Peters8dc73d22006-04-24 02:03:16 +00001799- Bug #1337990: clarified that ``doctest`` does not support examples
1800 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001808Core and builtins
1809-----------------
1810
Nick Coghlan43832302006-04-23 17:04:07 +00001811- PEP 338: -m command line switch now delegates to runpy.run_module
1812 allowing it to support modules in packages and zipfiles
1813
Martin v. Löwisc661b882006-04-20 04:54:23 +00001814- On Windows, .DLL is not an accepted file name extension for
1815 extension modules anymore; extensions are only found if they
1816 end in .PYD.
1817
Martin v. Löwisea62d252006-04-03 10:56:49 +00001818- Bug #1421664: sys.stderr.encoding is now set to the same value as
1819 sys.stdout.encoding.
1820
Neal Norwitz92e212f2006-04-03 04:48:37 +00001821- __import__ accepts keyword arguments.
1822
Georg Brandlccadf842006-03-31 18:54:53 +00001823- Patch #1460496: round() now accepts keyword arguments.
1824
Anthony Baxter262c00a2006-03-30 10:53:17 +00001825- Fixed bug #1459029 - unicode reprs were double-escaped.
1826
Hye-Shik Changd478f342006-03-23 12:32:36 +00001827- Patch #1396919: The system scope threads are reenabled on FreeBSD
1828 5.4 and later versions.
1829
Neal Norwitze98ccf62006-03-23 05:39:47 +00001830- Bug #1115379: Compiling a Unicode string with an encoding declaration
1831 now gives a SyntaxError.
1832
Georg Brandlabd1ff82006-03-18 07:59:59 +00001833- Previously, Python code had no easy way to access the contents of a
1834 cell object. Now, a ``cell_contents`` attribute has been added
1835 (closes patch #1170323).
1836
Tim Peterscf79aac2006-03-16 01:14:46 +00001837- Patch #1123430: Python's small-object allocator now returns an arena to
1838 the system ``free()`` when all memory within an arena becomes unused
1839 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1840 freed. Some applications will see a drop in virtual memory size now,
1841 especially long-running applications that, from time to time, temporarily
1842 use a large number of small objects. Note that when Python returns an
1843 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001844 platform C library will in turn return that memory to the operating system.
1845 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001846 appears to be effective at least on Microsoft C and gcc-based systems.
1847 Thanks to Evan Jones for hard work and patience.
1848
Georg Brandl533ff6f2006-03-08 18:09:27 +00001849- Patch #1434038: property() now uses the getter's docstring if there is
1850 no "doc" argument given. This makes it possible to legitimately use
1851 property() as a decorator to produce a read-only property.
1852
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001853- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1854 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1855 of requiring an int or long in slicing and a few other contexts, enabling
1856 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1857
Neal Norwitz995acdf2006-03-07 05:01:00 +00001858- Fixed various bugs reported by Coverity's Prevent tool.
1859
Brett Cannonbf364092006-03-01 04:25:17 +00001860- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1861 new exception base class, BaseException, which has a new message attribute.
1862 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1863 Raising a string exception now raises a DeprecationWarning.
1864
Thomas Woutersfb609f42006-02-28 16:37:25 +00001865- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1866 explicitly relative, using 'from .module import name' to mean 'from the same
1867 package as this module is in. Imports without dots still default to the
1868 old relative-then-absolute, unless 'from __future__ import
1869 absolute_import' is used.
1870
Brett Cannona7446e32006-02-27 23:39:10 +00001871- Properly check if 'warnings' raises an exception (usually when a filter set
1872 to "error" is triggered) when raising a warning for raising string
1873 exceptions.
1874
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001875- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001876 The name was removed from Include/code.h.
1877
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001878- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001879
Guido van Rossum1968ad32006-02-25 22:38:04 +00001880- Patch 1433928:
1881 - The copy module now "copies" function objects (as atomic objects).
1882 - dict.__getitem__ now looks for a __missing__ hook before raising
1883 KeyError.
1884
Tim Peters84ef21c2006-02-28 20:39:06 +00001885- PEP 343: with statement implemented. Needs ``from __future__ import
1886 with_statement``. Use of 'with' as a variable will generate a warning.
1887 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001888 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001889 The following objects have __context__ methods:
1890 - The built-in file type.
1891 - The thread.LockType type.
1892 - The following types defined by the threading module:
1893 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1894 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001895
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001896- Fix the encodings package codec search function to only search
1897 inside its own package. Fixes problem reported in patch #1433198.
1898
1899 Note: Codec packages should implement and register their own
1900 codec search function. PEP 100 has the details.
1901
Tim Peters9ea89d22006-06-04 03:26:02 +00001902- PEP 353: Using ``Py_ssize_t`` as the index type.
1903
1904- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1905 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1906 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1907 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1908 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001909
Neal Norwitzfc76d632006-01-10 06:03:13 +00001910- Patch #1400181, fix unicode string formatting to not use the locale.
1911 This is how string objects work. u'%f' could use , instead of .
1912 for the decimal point. Now both strings and unicode always use periods.
1913
Neal Norwitz671b9e32006-01-09 07:07:12 +00001914- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1915 configure would break checking curses.h.
1916
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001917- Bug #959576: The pwd module is now builtin. This allows Python to be
1918 built on UNIX platforms without $HOME set.
1919
Neal Norwitzc10978f2005-12-19 06:07:16 +00001920- Bug #1072182, fix some potential problems if characters are signed.
1921
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001922- Bug #889500, fix line number on SyntaxWarning for global declarations.
1923
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001924- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1925
Neal Norwitze7214a12005-12-18 05:03:17 +00001926- Support for converting hex strings to floats no longer works.
1927 This was not portable. float('0x3') now raises a ValueError.
1928
Barry Warsaw2a38a862005-12-18 01:27:35 +00001929- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001930 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001931 is now displayed in interactive prompt banner.
1932
Georg Brandlfa166682005-12-17 21:45:17 +00001933- Implementation of PEP 341 - Unification of try/except and try/finally.
1934 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001935 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001936
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001937- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1938 now encodes backslash correctly.
1939
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001940- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001942- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001943 and long longs.
1944
Neal Norwitz67715f02005-11-09 06:59:35 +00001945- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001946 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001947 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001948
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001949- Replaced most Unicode charmap codecs with new ones using the
1950 new Unicode translate string feature in the builtin charmap
1951 codec; the codecs were created from the mapping tables available
1952 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1953 encodings now include a mapping for the Apple logo)
1954
Tim Peterse3547fd2005-12-16 23:13:57 +00001955- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001956
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001957- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001958
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001959- A new AST parser implementation was completed. The abstract
1960 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001961 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001962
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001963- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001964 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1965
Neal Norwitz708e51a2005-10-03 04:48:15 +00001966- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1967
Neal Norwitz11bd1192005-10-03 00:54:56 +00001968- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1969 Provide a warning when a directory is passed on the command line.
1970
Neal Norwitz40d37812005-10-02 01:48:49 +00001971- Fix segfault with invalid coding.
1972
1973- SF bug #772896: unknown encoding results in MemoryError.
1974
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001975- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001976 supported a __len__() method which evaluated to False when the iterator
1977 was empty.
1978
Guido van Rossum630db602005-09-20 18:49:54 +00001979- On 64-bit platforms, when __len__() returns a value that cannot be
1980 represented as a C int, raise OverflowError.
1981
Skip Montanarof8948ca2005-09-19 03:54:46 +00001982- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001983 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001984
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001985- SF bug #893549: parsing keyword arguments was broken with a few format
1986 codes.
1987
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001988- Changes donated by Elemental Security to make it work on AIX 5.3
1989 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1990 bug #105470: test_pwd fails on 64bit system (Opteron).
1991
Guido van Rossum539c6622005-09-14 17:49:54 +00001992- Changes donated by Elemental Security to make it work on HP-UX 11 on
1993 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1994
Georg Brandl4550b8d2005-08-26 06:43:52 +00001995- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001996 (fixes bug #1119418).
1997
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001998- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1999
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002000- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2001 exceptions that cause a function to exit.
2002
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002003- The implementation of set() and frozenset() was revised to use its
2004 own internal data structure. Memory consumption is reduced by 1/3
2005 and there are modest speed-ups as well. The API is unchanged.
2006
Tim Petersde7990b2005-07-17 23:45:23 +00002007- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2008
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002009- SF bug #1229429: PyObject_CallMethod failed to decrement some
2010 reference counts in some error exit cases.
2011
Tim Petersecc6e6a2005-07-10 22:30:55 +00002012- SF bug #1185883: Python's small-object memory allocator took over
2013 a block managed by the platform C library whenever a realloc specified
2014 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002015 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002016 portable way to copy data from the C-managed block into Python's
2017 small-object space without risking a memory fault. Python's small-object
2018 realloc now leaves such blocks under the control of the platform C
2019 realloc.
2020
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002021- SF bug #1232517: An overflow error was not detected properly when
2022 attempting to convert a large float to an int in os.utime().
2023
Raymond Hettinger3296e692005-06-29 23:29:56 +00002024- SF bug #1224347: hex longs now print with lowercase letters just
2025 like their int counterparts.
2026
Michael W. Hudson188d4362005-06-20 16:52:57 +00002027- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2028 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2029 interpreter states; back out that fix and do a better job (see
2030 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2031 for a longer write-up of the problem).
2032
Michael W. Hudsondf888462005-06-03 14:41:55 +00002033- SF patch #1180995: marshal now uses a binary format by default when
2034 serializing floats.
2035
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002036- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2037 the routines that promise to produce IEEE 754 binary representations
2038 of floats now simply copy bytes around.
2039
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002040- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2041 278.
2042
Brett Cannonc3647ac2005-04-26 03:45:26 +00002043- patch #1109424: int, long, float, complex, and unicode now check for the
2044 proper magic slot for type conversions when subclassed. Previously the
2045 magic slot was ignored during conversion. Semantics now match the way
2046 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002047 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002048 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002049 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002050
Barry Warsawc8d907c2005-04-19 23:43:40 +00002051- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2052 NULL, now raise an AttributeError when attempting to set or delete the
2053 attribute. Previously a TypeError was raised, but this was inconsistent
2054 with the equivalent pure-Python implementation.
2055
Michael W. Hudson774479c2005-04-18 08:46:17 +00002056- It is now safe to call PyGILState_Release() before
2057 PyEval_InitThreads() (note that if there is reason to believe there
2058 are multiple threads around you still must call PyEval_InitThreads()
2059 before using the Python API; this fix is for extension modules that
2060 have no way of knowing if Python is multi-threaded yet).
2061
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002062- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2063 disabled caused a crash.
2064
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002065- Bug #1165306: instancemethod_new allowed the creation of a method
2066 with im_class == im_self == NULL, which caused a crash when called.
2067
Tim Petersecc6e6a2005-07-10 22:30:55 +00002068- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002069 fixes the crash seen in bug #1165761
2070
Raymond Hettinger96229b12005-03-11 06:49:40 +00002071- Added two new builtins, any() and all().
2072
Brett Cannon409d8f22005-03-05 06:47:57 +00002073- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002074 (e.g., ``class C(): pass`` is no longer a syntax error).
2075 Patch #1176012 added support to the 'parser' module and 'compiler' package
2076 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002077

2081 returning None.
2082
Tim Petersecc6e6a2005-07-10 22:30:55 +00002083- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002084 ('\') with a specific error message.
2085
Martin v. Löwisff232d72005-03-03 09:24:38 +00002086- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2087
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002088- Bug #1124295: the __name__ attribute of file objects was

2090
Tim Petersecc6e6a2005-07-10 22:30:55 +00002091- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002092 an ferror() call.
2093
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002094- min() and max() now support key= arguments with the same meaning as in
2095 list.sort().
2096
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002097- The peephole optimizer now performs simple constant folding in expressions:
2098 (2+3) --> (5).
2099
Raymond Hettingera422c342005-01-11 03:03:27 +00002100- set and frozenset objects can now be marshalled. SF #1098985.
2101
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002102- Bug #1077106: Poor argument checking could cause memory corruption
2103 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002104
Jeremy Hyltonab630502005-02-04 18:44:06 +00002105- The parser did not complain about future statements in illegal
2106 positions. It once again reports a syntax error if a future
2107 statement occurs after anything other than a doc string.
2108
Neil Schemenauercf52c072005-08-12 17:34:58 +00002109- Change the %s format specifier for str objects so that it returns a
2110 unicode instance if the argument is not an instance of basestring and
2111 calling __str__ on the argument returns a unicode instance.
2112
Tim Petersf4e69282006-02-27 17:15:31 +00002113- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2114 current thread state when the auto-GIL-state machinery knows about
2115 it (since the thread state is being deleted, continuing to remember it
2116 can't help, but can hurt if another thread happens to get created with
2117 the same thread id).

2148
Neal Norwitzb62c4332006-03-04 18:35:47 +00002149- The timing module is no longer built by default. It was deprecated

Nick Coghlan43832302006-04-23 17:04:07 +00002313- PEP 338: new module runpy defines a run_module function to support
2314 executing modules which provide access to source code or a code object
2315 via the PEP 302 import mechanisms.
2316
Anthony Baxter93f5b932006-04-03 08:05:07 +00002317- The email module's parsedate_tz function now sets the daylight savings

2325 in attribute values.
2326
Anthony Baxterc51ee692006-04-01 00:57:31 +00002327- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002328 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002329 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002330 module will not be built.
2331
Tim Petersc17976e2006-04-01 00:26:53 +00002332- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2333 aren't officially supported here, and trying to use them will probably
2334 raise an exception some day. But dicts have been allowed, and "mostly
2335 worked", so support for them won't go away without warning.
2336
Georg Brandl338ef7d2006-03-31 18:42:16 +00002337- Bug #1445068: getpass.getpass() can now be given an explicit stream
2338 argument to specify where to write the prompt.
2339

2349 to make it easier to monitor when daemon threads have completed
2350 processing all enqueued tasks. Patch #1455676.
2351
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002352- popen2.Popen objects now preserve the command in a .cmd attribute.

2355
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002356- email 4.0 package now integrated. This is largely the same as the email 3.0
2357 package that was included in Python 2.3, except that PEP 8 module names are
2358 now used (e.g. mail.message instead of email.Message). The MIME classes
2359 have been moved to a subpackage (e.g. email.mime.text instead of
2360 email.MIMEText). The old names are still supported for now. Several
2361 deprecated Message methods have been removed and lots of bugs have been
2362 fixed. More details can be found in the email package documentation.
2363
Walter Dörwald40108c92006-03-27 08:15:44 +00002364- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2365 (a subclass of tuple) that provides incremental decoders and encoders
2366 (a way to use stateful codecs without the stream API). Python functions
2367 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2368 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2369 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002370
Walter Dörwald067db482006-03-15 22:17:27 +00002371- Patch #1359365: Calling next() on a closed StringIO.String object raises
2372 a ValueError instead of a StopIteration now (like file and cString.String do).
2373 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2374 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002375
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002376- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002448 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2449 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2450 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2451 Ronald L. Rivest offered this advice for Python:
2452
2453 "The consensus of researchers in this area (at least as
2454 expressed at the NIST Hash Function Workshop 10/31/05),
2455 is that SHA-256 is a good choice for the time being, but
2456 that research should continue, and other alternatives may
2457 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002458
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002459- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger267b8682005-03-27 10:47:39 +00002575- decimal operator and comparison methods now return NotImplemented
2576 instead of raising a TypeError when interacting with other types. This
2577 allows other classes to implement __radd__ style methods and have them
2578 work as expected.
2579
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002580- Bug #1163325: Decimal infinities failed to hash. Attempting to
2581 hash a NaN raised an InvalidOperation instead of a TypeError.
2582
Tim Petersecc6e6a2005-07-10 22:30:55 +00002583- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002584 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2585
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002586- Patch #1043890: Add extractall method to tarfile.
2587
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002588- Patch #1075887: Don't require MSVC in distutils if there is nothing
2589 to build.
2590
Martin v. Löwis637431b2005-03-03 23:12:42 +00002591- Patch #1103407: Properly deal with tarfile iterators when untarring
2592 symbolic links on Windows.
2593
Tim Petersecc6e6a2005-07-10 22:30:55 +00002594- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002595 profile.py if available.
2596
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002597- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2598
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002599- Patch #1117454: Remove code to special-case cookies without values
2600 in LWPCookieJar.
2601
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002602- Patch #1117339: Add cookielib special name tests.
2603
Martin v. Löwise869eb12005-03-03 09:46:07 +00002604- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2605
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002606- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2607
Martin v. Löwisdf241532005-03-03 08:17:42 +00002608- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2609
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002610- Patch #1104111: Alter setup.py --help and --help-commands.
2611
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002612- Patch #1121234: Properly cleanup _exit and tkerror commands.
2613
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002614- Patch #1049151: xdrlib now unpacks booleans as True or False.
2615
Raymond Hettingerbab41432005-02-05 01:31:19 +00002616- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2617
Guido van Rossumd0641422005-02-03 15:01:24 +00002618- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2619 disables recursive traversal through instance attributes, which can
2620 be exploited in various ways.
2621
Tim Peterse3547fd2005-12-16 23:13:57 +00002622- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002623 flags on the HTTP listening socket.
2624
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002625- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2626 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2627
Fred Drakefbdeaad2006-07-29 16:56:15 +00002628- Patches #893642, #1039083: add allow_none, encoding arguments to
2629 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002630
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002631- Bug #1110478: Revert os.environ.update to do putenv again.
2632
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002633- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2634
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002635- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2636
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002637- Enhancements to the csv module:
2638
2639 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002640 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002641 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002642 + Dialect parameter parsing has been re-implemented to improve error
2643 reporting.
2644 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2645 dictates.
2646 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002647 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002648 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002649 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2650 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002651 + reader now allows \r characters to be quoted (previously it only allowed
2652 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002653 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002654 + Dialect classes passed to the module are no longer instantiated by
2655 the module before being parsed (the former validation scheme required
2656 this, but the mechanism was unreliable).
2657 + The dialect registry now contains instances of the internal
2658 C-coded dialect type, rather than references to python objects.
2659 + the internal c-coded dialect type is now immutable.
2660 + register_dialect now accepts the same keyword dialect specifications
2661 as the reader and writer, allowing the user to register dialects
2662 without first creating a dialect class.
2663 + a configurable limit to the size of parsed fields has been added -
2664 previously, an unmatched quote character could result in the entire
2665 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002666 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002667 the parser field size limit (returning the former limit). The initial
2668 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002669 + A line_num attribute has been added to the reader object, which tracks
2670 the number of lines read from the source iterator. This is not
2671 the same as the number of records returned, as records can span
2672 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002673 + reader and writer objects were not being registered with the cyclic-GC.
2674 This has been fixed.
2675
Brett Cannone6539c42005-01-08 02:43:53 +00002676- _DummyThread objects in the threading module now delete self.__block that is
2677 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2678 lock primitives tend to be limited in number and thus should not be wasted on
2679 a _DummyThread object. Fixes bug #1089632.
2680
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002681- The imghdr module now detects Exif files.
2682
Raymond Hettinger6065d322004-12-20 23:51:53 +00002683- StringIO.truncate() now correctly adjusts the size attribute.
2684 (Bug #951915).
2685
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002686- locale.py now uses an updated locale alias table (built using
2687 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2688 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002689 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002690
Raymond Hettinger3557f422004-12-07 12:02:02 +00002691- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2692
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002693- the pickle module no longer accepts the deprecated None option in the
2694 args tuple returned by __reduce__().
2695
Brett Cannon84667c02004-12-07 03:25:18 +00002696- optparse now optionally imports gettext. This allows its use in setup.py.
2697
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002698- the pickle module no longer uses the deprecated bin parameter.
2699
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002700- the shelve module no longer uses the deprecated binary parameter.
2701
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002702- the pstats module no longer uses the deprecated ignore() method.
2703
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002704- the filecmp module no longer uses the deprecated use_statcache argument.
2705
Raymond Hettinger664347b2004-12-04 21:21:53 +00002706- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2707 extended or overridden by subclasses. Formerly, the subclassed method would
2708 be ignored by the rest of the module. (Bug #1078905).
2709
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002710- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002711 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002712
Walter Dörwald36733692004-12-22 12:50:50 +00002713- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2714 once when a size argument is given. This prevents a buffer overflow in the
2715 tokenizer with very long source lines.
2716
Barry Warsaw538561e2006-01-01 21:48:54 +00002717- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2718 immediately after creating the object, without any intervening
2719 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002720
Skip Montanaro05885812005-01-16 20:48:27 +00002721- The reconvert.quote function can now emit triple-quoted strings. The
2722 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002723
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002724- ``UserString.MutableString`` now supports negative indices in
2725 ``__setitem__`` and ``__delitem__``
2726
Greg Ward40407942005-03-05 02:53:17 +00002727- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2728 correctly.
2729
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002730- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2731 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2732 character even if the user has passed a size parameter to get a proper
2733 line ending. Remove the special handling of a "\r\n" that has been split
2734 between two lines.
2735
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002736- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2737 about illegal code points. The codec now supports PEP 293 style error
2738 handlers.
2739
Walter Dörwald78a78b02005-09-01 12:04:29 +00002740- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002741 from the input stream, so that the output is a byte string in the correct
2742 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002743
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002744- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2745 considering it exactly like a '*'.
2746
Walter Dörwald007f8df2005-10-09 19:42:27 +00002747- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2748 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002749
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002750- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2751
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002752- Patch #1413711: Certain patterns of differences were making difflib
2753 touch the recursion limit.
2754
Walter Dörwald58917a62006-03-31 15:26:22 +00002755- Bug #947906: An object oriented interface has been added to the calendar
2756 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002757 called as a script (e.g. via ``python -mcalendar``). Localized month and
2758 weekday names can be ouput (even if an exotic encoding is used) using
2759 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002760
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002761Build
2762-----
2763
Neal Norwitz602d3392006-03-31 08:21:40 +00002764- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2765 by using -mieee gcc option.
2766
Martin v. Löwis86d66262006-02-17 08:40:11 +00002767- Patch #1432345: Make python compile on DragonFly.
2768
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002769- Build support for Win64-AMD64 was added.
2770
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002771- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2772
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002773- Patch #881820: look for openpty and forkpty also in libbsd.
2774
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002775- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2776 The zlib module is now builtin on Windows.
2777
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002778- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2779
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002780- Bug #1189330: configure did not correctly determine the necessary
2781 value of LINKCC if python was built with GCC 4.0.
2782
Trent Mick8321b422005-07-26 02:29:21 +00002783- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2784 vulnerability in zlib 1.2.1 and 1.2.2.
2785
Brett Cannon08cd5982005-04-24 22:26:38 +00002786- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2787 flags that change binary compatibility. Changes were also made to
2788 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002789 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002790
Bob Ippolitoed233462005-03-29 13:47:59 +00002791- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2792 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2793 no longer exists). This configure patch makes things right.
2794
Martin v. Löwise2713be2005-03-08 15:03:08 +00002795- Bug #1158607: Build with --disable-unicode again.
2796
Brett Cannon46d96232005-02-16 00:07:19 +00002797- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2798 defined. Discovered as a result of not being able to build on OS X.
2799
Brett Cannon516592f2004-12-07 00:42:59 +00002800- setup.py now uses the directories specified in LDFLAGS using the -L option
2801 and in CPPFLAGS using the -I option for adding library and include
2802 directories, respectively, for compiling extension modules against. This has
2803 led to the core being compiled using the values in CPPFLAGS. It also removes
2804 the need for the special-casing of both DarwinPorts and Fink for darwin since
2805 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2806 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2807 Fink, ``-I/opt/local/include`` for DarwinPorts).
2808
Brett Cannon43802422005-02-10 20:48:03 +00002809- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2810 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2811 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2812 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002814C API
2815-----
2816
Tim Petersc9d78aa2006-03-26 23:27:58 +00002817- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2818 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2819 is obtained via the ``PyObject_`` family, it must be released via the
2820 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2821 always been officially true, but when Python's small-object allocator was
2822 introduced, an attempt was made to cater to a few extension modules
2823 discovered at the time that obtained memory via ``PyObject_New`` but
2824 released it via ``PyMem_DEL``. It's years later, and if such code still
2825 exists it will fail now (probably with segfaults, but calling wrong
2826 low-level memory management functions can yield many symptoms).
2827
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002828- Added a C API for set and frozenset objects.
2829
Raymond Hettinger66517482004-12-03 11:45:13 +00002830- Removed PyRange_New().
2831
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002832- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2833 mapping argument now. This string is used as a mapping table. Byte values
2834 greater than the length of the string and 0xFFFE are treated as undefined
2835 mappings.
