666-----------------
667
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000668- Make _PyGILState_NoteThreadState() static, it was not used anywhere
669 outside of pystate.c and should not be necessary.
670
Brett Cannon19d76c52006-09-09 07:18:44 +0000671- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
672 allows calling unicode() on exceptions classes directly to succeed.
673
Georg Brandlecab6232006-09-06 06:47:02 +0000674- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000689- The return tuple from str.rpartition(sep) is (tail, sep, head) where
690 head is the original string if sep was not found.
691
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000692- Bug #1520864: unpacking singleton tuples in list comprehensions and
693 generator expressions (x for x, in ... ) works again. Fixing this problem
694 required changing the .pyc magic number. This means that .pyc files
695 generated before 2.5c2 will be regenerated.

808-----------------
809
Neal Norwitz24b6f202006-09-05 04:43:56 +0000810- Fix infinite recursion when subclassing long and overriding __hash__.
811
812- Fix concatenation (+=) of long strings.
813
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000814- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000815 compared equal or unequal to a string and a UnicodeDecodeError
816 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000817
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000818 Instead, the equal (==) and unequal (!=) comparison operators will
819 now issue a UnicodeWarning and interpret the two objects as
820 unequal. The UnicodeWarning can be filtered as desired using
821 the warning framework, e.g. silenced completely, turned into an
822 exception, logged, etc.
823
824 Note that compare operators other than equal and unequal will still
825 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000826
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000827- Fix segfault when doing string formatting on subclasses of long.
828
829- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
830 with new-style classes.
831
832- Fix bug related to __len__ functions returning negative values with
833 classic classes.
834
835- Patch #1538606, Fix __index__() clipping. There were some problems
836 discovered with the API and how integers that didn't fit into Py_ssize_t
837 were handled. This patch attempts to provide enough alternatives
838 to effectively use __index__.
839
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000840- Bug #1536021: __hash__ may now return long int; the final hash
841 value is obtained by invoking hash on the long int.
842
Thomas Hellerab1049c2006-08-08 17:37:00 +0000843- Bug #1536786: buffer comparison could emit a RuntimeWarning.
844
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000845- Bug #1535165: fixed a segfault in input() and raw_input() when
846 sys.stdin is closed.
847
Thomas Heller74d36f02006-08-04 18:17:40 +0000848- On Windows, the PyErr_Warn function is now exported from
849 the Python dll again.
850
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000851- Bug #1191458: tracing over for loops now produces a line event
852 on each iteration. Fixing this problem required changing the .pyc
853 magic number. This means that .pyc files generated before 2.5c1
854 will be regenerated.
855
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000856- Bug #1333982: string/number constants were inappropriately stored
857 in the byte code and co_consts even if they were not used, ie
858 immediately popped off the stack.
859
Georg Brandle9462c72006-08-04 18:03:37 +0000860- Fixed a reference-counting problem in property().

864-------
865
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000866- Fix a bug in the ``compiler`` package that caused invalid code to be
867 generated for generator expressions.
868
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000869- The distutils version has been changed to 2.5.0. The change to
870 keep it programmatically in sync with the Python version running
871 the code (introduced in 2.5b3) has been reverted. It will continue
872 to be maintained manually as static string literal.
873
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000874- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000875 and this cannot be converted to the required C type, an exception is
876 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000877 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000878
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000879- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000880 an exception.
881
Tim Peterscbdd3502006-09-05 01:47:53 +0000882- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000883 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000884 workarounds for clocks with low resolution, to stop the code yielding
885 duplicate UUIDs.
886
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000887- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
888 before raising SystemExit, allowing IDLE to honor quit() and exit().
889
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000890- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
891
Georg Brandl7a1af772006-08-14 21:55:28 +0000892- Patch #1536071: trace.py should now find the full module name of a

901 str(exception) raised an exception.
902
Neil Schemenauer06ded092006-08-04 16:20:30 +0000903- Fix a bug in the ``compiler`` package that caused invalid code to be
904 generated for nested functions.

919
Thomas Heller86720042006-08-14 11:17:48 +0000920- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
921 uses the _as_parameter_ attribute when objects are passed to foreign
922 function calls. The ctypes version number was changed to 1.0.1.
923
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000924- Bug #1530559, struct.pack raises TypeError where it used to convert.

964
Tim Peters4643c2f2006-08-10 22:45:34 +0000965- Bug #1069160. Internal correctness changes were made to
966 ``PyThreadState_SetAsyncExc()``. A test case was added, and
967 the documentation was changed to state that the return value
968 is always 1 (normal) or 0 (if the specified thread wasn't found).

976Core and builtins
977-----------------
978
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000979- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000980 returned a long (see PEP 353).
981
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000982- Bug #1515471: string.replace() accepts character buffers again.
983
Neal Norwitz07aadb12006-07-30 06:55:48 +0000984- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
985 This provides the proper warning for struct.pack().
986 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
987
Neal Norwitz0d62a062006-07-30 06:53:31 +0000988- Patch #1531113: Fix augmented assignment with yield expressions.
989 Also fix a SystemError when trying to assign to yield expressions.
990
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000991- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
992 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
993 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
994 excessive filesystem operations during imports.
995
Tim Petersbc24eee2006-07-27 01:14:53 +0000996- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
997 operations on signed longs that are formally undefined by C.
998 Unfortunately, at least one compiler now cares about that, so complicated
999 the code to make that compiler happy again.
1000
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001001- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1002
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001003- Patch #1232023: Stop including current directory in search
1004 path on Windows.
1005
Neal Norwitze1fdb322006-07-21 05:32:28 +00001006- Fix some potential crashes found with failmalloc.
1007
Neal Norwitze7563102006-07-17 01:00:16 +00001008- Fix warnings reported by Klocwork's static analysis tool.
1009
Neal Norwitz84be93b2006-07-16 01:50:38 +00001010- Bug #1512814, Fix incorrect lineno's when code within a function
1011 had more than 255 blank lines.
1012
Georg Brandl9dceedb2006-07-12 15:31:17 +00001013- Patch #1521179: Python now accepts the standard options ``--help`` and
1014 ``--version`` as well as ``/?`` on Windows.
1015
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001016- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001017 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001018 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001019
Tim Peters112aad32006-07-19 00:03:19 +00001020- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001021 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001022 new ``sys._current_frames()`` returns a dictionary with one entry,
1023 mapping the faux "thread id" 0 to the current frame.
1024
Ronald Oussoren3075e162006-07-25 20:28:55 +00001025- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001026

Neal Norwitza1f10902006-07-12 07:28:29 +00001028Library
1029-------
1030
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001031- Correction of patch #1455898: In the mbcs decoder, set final=False
1032 for stream decoder, but final=True for the decode function.
1033
Georg Brandl07fec3a2006-08-01 18:49:24 +00001034- os.urandom no longer masks unrelated exceptions like SystemExit or
1035 KeyboardInterrupt.
1036
Tim Peters4643c2f2006-08-10 22:45:34 +00001037- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001038 shutil.copytree on Windows
1039
Georg Brandle34ac7c2006-07-30 11:07:23 +00001040- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1041 refers to file descriptors, not file objects.
1042
Tim Peterscbdd3502006-09-05 01:47:53 +00001043- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001044 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001045 #1513611, and probably others.
1046
Georg Brandledd9b0d2006-07-29 09:33:26 +00001047- Bug #1441397: The compiler module now recognizes module and function
1048 docstrings correctly as it did in Python 2.4.
1049
Tim Peters6f681472006-07-27 23:44:37 +00001050- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1051 lost that tests are sorted by name before being run. This rarely
1052 matters for well-written tests, but can create baffling symptoms if
1053 side effects from one test to the next affect outcomes. ``DocTestFinder``
1054 has been changed to sort the list of tests it returns.
1055
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001056- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001057 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001058
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001059- Bug #978833: Really close underlying socket in _socketobject.close.
1060
Georg Brandldb232dc2006-08-20 13:15:43 +00001061- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1062 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001063
Georg Brandlcf0c1722006-07-26 07:23:32 +00001064- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1065 to recursive calls and call it with the failing package name.
1066
Martin v. Löwis0b483032006-07-25 09:53:12 +00001067- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1068
Georg Brandlc13c34c2006-07-24 14:09:56 +00001069- Patch #1515343: Fix printing of deprecated string exceptions with a
1070 value in the traceback module.
1071
Greg Ward48fae7a2006-07-23 16:05:51 +00001072- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1073
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001074- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1075
Brett Cannoncaebe222006-07-18 04:41:36 +00001076- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1077 argument tuple. For arguments where zero is illegal, the value is forced to
1078 the minimum value that is correct. This is to support an undocumented but
1079 common way people used to fill in inconsequential information in the time
1080 tuple pre-2.4.
1081
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001082- Patch #1220874: Update the binhex module for Mach-O.
1083
Barry Warsawb110bad2006-07-21 14:51:07 +00001084- The email package has improved RFC 2231 support, specifically for
1085 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1086 (name*0=<blah>) parameter continuations. This may change the types of
1087 values returned from email.message.Message.get_param() and friends.
1088 Specifically in some cases where non-encoded continuations were used,
1089 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1090 will just return the string (since non-encoded continuations don't have
1091 charset and language parts).
1092
1093 Also, whereas % values were decoded in all parameter continuations, they are
1094 now only decoded in encoded parameter parts.
1095
Ronald Oussoren3075e162006-07-25 20:28:55 +00001096- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1097
1098- Bug #1517996: IDLE now longer shows the default Tk menu when a
1099 path browser, class browser or debugger is the frontmost window on MacOS X
1100
Barry Warsaw00decd72006-07-27 23:43:15 +00001101- Patch #1520294: Support for getset and member descriptors in types.py,
1102 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1103 of an object against these built-in types and more importantly, for getting
1104 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitz9b0ca792006-08-02 06:46:21 +00001110- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1111 a socket operation on a socket with a timeout, the exception will be
1112 caught correctly. Previously, the exception was not caught.
1113
Thomas Heller1393d6a2006-07-28 21:43:20 +00001114- Patch #1529514: The _ctypes extension is now compiled on more
1115 openbsd target platforms.
1116
Tim Peters9cab5932006-07-28 00:30:00 +00001117- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1118 a memory leak, affecting pickles and deep copies.
1119
Tim Petersbc24eee2006-07-27 01:14:53 +00001120- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1122
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001123- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1124
Thomas Hellerce049a02006-07-14 17:51:14 +00001125- Patch #1521817: Index range checking on ctypes arrays containing
1126 exactly one element enabled again. This allows iterating over these
1127 arrays, without the need to check the array size before.
1128
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001129- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001130 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001131 /dev/null in certain cases; this is now fixed.
1132
Thomas Heller47d7a062006-07-12 08:43:47 +00001133- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1134 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001135
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001136- Because of a misspelled preprocessor symbol, ctypes was always
1137 compiled without thread support; this is now fixed.
1138
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001139- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1140 methods now allow their database parameter to be None as the
1141 sleepycat API allows.
1142
Matt Flemingec926502006-07-28 11:27:27 +00001143- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1144 bluetooth API compared with Linux and FreeBSD.
1145

1147-----
1148
1149- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1150 how long the test file should take to play. Now accepts taking 2.93 secs
1151 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1152
Georg Brandl4793aa32006-07-28 18:31:39 +00001153- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1154 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1155 run via ``regrtest.py``. Now they do.

1165- PythonLauncher now works correctly when the path to the script contains
1166 characters that are treated specially by the shell (such as quotes).
1167
1168- Bug #1527397: PythonLauncher now launches scripts with the working directory
1169 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001170 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001171 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001182- Bug #1441486: The literal representation of -(sys.maxint - 1)
1183 again evaluates to a int object, not a long.
1184
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001185- Bug #1501934: The scope of global variables that are locally assigned
1186 using augmented assignment is now correctly determined.
1187
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001188- Bug #927248: Recursive method-wrapper objects can now safely
1189 be released.
1190
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001191- Bug #1417699: Reject locale-specific decimal point in float()
1192 and atof().
1193
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001194- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1195 omit a default "error" argument for NULL pointer. This allows
1196 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001197
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001198- Bug #1519018: 'as' is now validated properly in import statements.
1199
Neal Norwitz28746ab2006-07-09 22:14:42 +00001200- On 64 bit systems, int literals that use less than 64 bits are
1201 now ints rather than longs.
1202
Neal Norwitzed657552006-07-10 00:04:44 +00001203- Bug #1512814, Fix incorrect lineno's when code at module scope
1204 started after line 256.
1205
Tim Peters32a83612006-07-10 21:08:24 +00001206- New function ``sys._current_frames()`` returns a dict mapping thread
1207 id to topmost thread stack frame. This is for expert use, and is
1208 especially useful for debugging application deadlocks. The functionality
1209 was previously available in Fazal Majid's ``threadframe`` extension
1210 module, but it wasn't possible to do this in a wholly threadsafe way from
1211 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001216- Bug #1257728: Mention Cygwin in distutils error message about a missing
1217 VS 2003.
1218
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001219- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1220
Tim Peters32a83612006-07-10 21:08:24 +00001221- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001222 environment variable to be set in order to the SDK environment
1223 for finding the compiler, include files, etc.
1224
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001225- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1226
Nick Coghlan2d792252006-07-06 13:47:18 +00001227- warnings.py now ignores ImportWarning by default
1228
Thomas Woutersadd19112006-07-05 11:03:49 +00001229- string.Template() now correctly handles tuple-values. Previously,
1230 multi-value tuples would raise an exception and single-value tuples would
1231 be treated as the value they contain, instead.
1232
Martin v. Löwisede77f52006-07-03 13:01:35 +00001233- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1234 even if some data are received.
1235
Martin v. Löwis45482392006-07-03 12:28:58 +00001236- Bug #1267547: Put proper recursive setup.py call into the

1240 degrees and radians.
1241
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001242- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001243 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001244
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001245- Bug #1514703: Only setup canvas window in turtle when the canvas
1246 is created.
1247
Martin v. Löwis7596e832006-07-01 15:33:37 +00001248- Bug #1513223: .close() of a _socketobj now releases the underlying
1249 socket again, which then gets closed as it becomes unreferenced.
1250
Fred Drake10497c82006-06-29 02:57:48 +00001251- Bug #1504333: Make sgmllib support angle brackets in quoted
1252 attribute values.
1253
1254- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1255 sgmllib ('[' and ']' were not accepted).
1256
Georg Brandl1be63af2006-06-28 20:23:25 +00001257- Fix a bug in the turtle module's end_fill function.
1258
Brett Cannon53ab5b72006-06-22 16:49:14 +00001259- Bug #1510580: The 'warnings' module improperly required that a Warning
1260 category be either a types.ClassType and a subclass of Warning. The proper
1261 check is just that it is a subclass with Warning as the documentation states.
1262
Georg Brandlad29e632006-06-21 17:45:17 +00001263- The compiler module now correctly compiles the new try-except-finally
1264 statement (bug #1509132).
1265
Neal Norwitz60373cd2006-06-22 06:30:50 +00001266- The wsgiref package is now installed properly on Unix.
1267
Vinay Sajip28e57612006-07-01 10:45:20 +00001268- A bug was fixed in logging.config.fileConfig() which caused a crash on
1269 shutdown when fileConfig() was called multiple times.
1270
Gerhard Häring762fbd32006-07-02 17:48:30 +00001271- The sqlite3 module did cut off data from the SQLite database at the first
1272 null character before sending it to a custom converter. This has been fixed
1273 now.
1274
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001275Extension Modules
1276-----------------
1277
Tim Peters112aad32006-07-19 00:03:19 +00001278- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1279 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1280 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001281
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001282- Assigning None to pointer type fields in ctypes structures possible
1283 overwrote the wrong fields, this is fixed now.
1284
1285- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1286 on non-Windows platforms.
1287
1288- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1289 integer or long, without range checking.
1290
1291- Patch #1517790: It is now possible to use custom objects in the ctypes
1292 foreign function argtypes sequence as long as they provide a from_param
1293 method, no longer is it required that the object is a ctypes type.
1294
1295- The '_ctypes' extension module now works when Python is configured
1296 with the --without-threads option.
1297
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001298- Bug #1513646: os.access on Windows now correctly determines write
1299 access, again.
1300
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001301- Bug #1512695: cPickle.loads could crash if it was interrupted with
1302 a KeyboardInterrupt.
1303
Neal Norwitza12aa882006-07-06 06:45:08 +00001304- Bug #1296433: parsing XML with a non-default encoding and
1305 a CharacterDataHandler could crash the interpreter in pyexpat.
1306
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001307- Patch #1516912: improve Modules support for OpenVMS.

1310-----
1311
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001312- Automate Windows build process for the Win64 SSL module.
1313
Tim Peters32a83612006-07-10 21:08:24 +00001314- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001315 Previously, the slight difference could cause compilation errors of the
1316 'zlib' module on systems with more than one version of zlib.
1317
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001318- The MSI compileall step was fixed to also support a TARGETDIR
1319 with spaces in it.
1320
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001321- Bug #1517388: sqlite3.dll is now installed on Windows independent
1322 of Tcl/Tk.
1323
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001324- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001325 trying to be installed even though it's empty.

1337 documentation for the warnings module.
1338
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001339- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001346
Anthony Baxterd1136802006-06-19 12:04:15 +00001347*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001348
1349Core and builtins
1350-----------------
1351
Georg Brandla56b9152006-06-19 06:35:54 +00001352- Patch #1507676: Error messages returned by invalid abstract object operations
1353 (such as iterating over an integer) have been improved and now include the
1354 type of the offending object to help with debugging.
1355
Brett Cannonea3912b2006-06-13 21:46:41 +00001356- Bug #992017: A classic class that defined a __coerce__() method that returned
1357 its arguments swapped would infinitely recurse and segfault the interpreter.
1358
Neal Norwitz909eb122006-06-12 02:13:21 +00001359- Fix the socket tests so they can be run concurrently.
1360
Neal Norwitzb9845e72006-06-12 02:11:18 +00001361- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001362 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001363
Brett Cannon22565aa2006-06-09 22:31:23 +00001364- Bug #532646: object.__call__() will continue looking for the __call__
1365 attribute on objects until one without one is found. This leads to recursion
1366 when you take a class and set its __call__ attribute to an instance of the
1367 class. Originally fixed for classic classes, but this fix is for new-style.
1368 Removes the infinite_rec_3 crasher.
1369
Georg Brandl24250812006-06-09 18:45:48 +00001370- The string and unicode methods startswith() and endswith() now accept
1371 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1372
Brett Cannonde3b0522006-06-08 17:00:45 +00001373- Buffer objects, at the C level, never used the char buffer
1374 implementation even when the char buffer for the wrapped object was
1375 explicitly requested (originally returned the read or write buffer).
1376 Now a TypeError is raised if the char buffer is not present but is
1377 requested.
1378
Georg Brandlddbaa662006-06-04 21:56:52 +00001379- Patch #1346214: Statements like "if 0: suite" are now again optimized
1380 away like they were in Python 2.4.
1381
Georg Brandlb7c8f542006-05-27 12:30:25 +00001382- Builtin exceptions are now full-blown new-style classes instead of
1383 instances pretending to be classes, which speeds up exception handling
1384 by about 80% in comparison to 2.5a2.
1385
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001386- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1387 Unicode 4.1.
1388
Georg Brandlf4ef1162006-05-26 18:03:31 +00001389- Patch #921466: sys.path_importer_cache is now used to cache valid and
1390 invalid file paths for the built-in import machinery which leads to
1391 fewer open calls on startup.
1392
Tim Peters696cf432006-05-24 21:10:40 +00001393- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1394 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1395 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1396 the number of input digits (it was and remains linear-time for bases
1397 2, 4, 8, 16 and 32).
1398
Tim Petersb713ec22006-05-23 18:45:30 +00001399- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1400 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1401 an integer close to ``sys.maxint``. This was repaired by patch
1402 #1335972, which also gives a nice speedup.
1403
Richard Jonescebbefc2006-05-23 18:28:17 +00001404- Patch #1337051: reduced size of frame objects.
1405
1406- PyErr_NewException now accepts a tuple of base classes as its
1407 "base" parameter.
1408
Richard Jones7c88dcc2006-05-23 10:37:38 +00001409- Patch #876206: function call speedup by retaining allocated frame
1410 objects.
1411
Georg Brandl7b90e162006-05-18 07:01:27 +00001412- Bug #1462152: file() now checks more thoroughly for invalid mode
1413 strings and removes a possible "U" before passing the mode to the
1414 C library function.
1415
Neal Norwitz1004a532006-05-15 07:17:23 +00001416- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1417
Neal Norwitz373f0a72006-05-15 07:04:36 +00001418- Bug #1487966: Fix SystemError with conditional expression in assignment
1419
Martin v. Löwis879768d2006-05-11 13:28:43 +00001420- WindowsError now has two error code attributes: errno, which carries
1421 the error values from errno.h, and winerror, which carries the error
1422 values from winerror.h. Previous versions put the winerror.h values
1423 (from GetLastError()) into the errno attribute.
1424
Martin v. Löwis77736712006-05-04 05:51:03 +00001425- Patch #1475845: Raise IndentationError for unexpected indent.
1426
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001427- Patch #1479181: split open() and file() from being aliases for each other.
1428
Tim Peters44bd9862006-06-01 13:49:23 +00001429- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1430 methods were always silently ignored by dictionaries when comparing keys.
1431 They are now passed through (except when using the C API function
1432 ``PyDict_GetItem()``, whose semantics did not change).
1433
1434- Bug #1456209: In some obscure cases it was possible for a class with a
1435 custom ``__eq__()`` method to confuse dict internals when class instances
1436 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1437 No, you don't have any code that did this ;-)

1440-----------------
1441
Trent Mick960a3f82006-06-28 20:30:41 +00001442- Bug #1295808: expat symbols should be namespaced in pyexpat
1443
1444- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1445
Brett Cannon6ee7d012006-06-08 16:23:04 +00001446- Change binascii.hexlify to accept a read-only buffer instead of only a char
1447 buffer and actually follow its documentation.
1448
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001449- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1450
Nick Coghlanc649ec52006-05-29 12:43:05 +00001451- Patch #1478788 (modified version): The functional extension module has
1452 been renamed to _functools and a functools Python wrapper module added.
1453 This provides a home for additional function related utilities that are
1454 not specifically about functional programming. See PEP 309.
1455
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001456- Patch #1493701: performance enhancements for struct module.
1457
Georg Brandl378d5922006-05-17 14:26:50 +00001458- Patch #1490224: time.altzone is now set correctly on Cygwin.
1459
Georg Brandl8d3342b2006-05-16 07:38:27 +00001460- Patch #1435422: zlib's compress and decompress objects now have a
1461 copy() method.
1462
Andrew MacIntyre92913322006-06-13 15:04:24 +00001463- Patch #1454481: thread stack size is now tunable at runtime for thread
1464 enabled builds on Windows and systems with Posix threads support.
1465
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001466- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1467 (up to the system limit of 32K characters).
1468
1469- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1470 As a result, these functions now raise WindowsError instead of OSError.
1471
Tim Peters7a822da2006-05-25 21:50:17 +00001472- ``time.clock()`` on Win64 should use the high-performance Windows
1473 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1474 Windows platforms).
1475
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001476- Calling Tk_Init twice is refused if the first call failed as that
1477 may deadlock.
1478
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001479- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1480 accept it without potentially using an uninitialized pointer.
1481
1482- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1483 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1488
Gregory P. Smith372b5832006-06-05 18:48:21 +00001489- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1490 parameter is supplied. [SF pybsddb bug #1477863]
1491
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001492- bsddb: the __len__ method of a DB object has been fixed to return correct
1493 results. It could previously incorrectly return 0 in some cases.
1494 Fixes SF bug 1493322 (pybsddb bug 1184012).
1495
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001496- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1497 aborts the db transaction safely when a modifier callback fails.
1498 Fixes SF python patch/bug #1408584.
1499
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001500- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001501 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001502 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1503 database calls that would previously deadlock. [SF python bug #775414]

1533 double-byte encodings.
1534
Tim Peters43898b42006-06-14 04:09:25 +00001535- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1536 guarantee that adjacent triples in the return list always describe
1537 non-adjacent blocks. Previously, a pair of matching blocks could end
1538 up being described by multiple adjacent triples that formed a partition
1539 of the matching pair.

1548
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001549- The wsgiref package has been added to the standard library.
1550
Nick Coghlan676725d2006-06-08 13:54:49 +00001551- The functions update_wrapper() and wraps() have been added to the functools
1552 module. These make it easier to copy relevant metadata from the original
1553 function when writing wrapper functions.
1554
Tim Petersd6a9eef2006-06-05 01:48:21 +00001555- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1556 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001557
Martin v. Löwis3f767792006-06-04 19:36:28 +00001558- Patch #1359618: Speed up charmap encoder by using a trie structure
1559 for lookup.
1560
Tim Petersd609b1a2006-06-02 23:22:51 +00001561- The functions in the ``pprint`` module now sort dictionaries by key
1562 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1563 if and only if its display required more than one line, although that
1564 wasn't documented. The new behavior increases predictability; e.g.,
1565 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1566

Georg Brandlb89316f2006-05-17 15:51:16 +00001577- Patch #1180296: Two new functions were added to the locale module:
1578 format_string() to get the effect of "format % items" but locale-aware,
1579 and currency() to format a monetary number with currency sign.

1588 stdout arguments, making it possible to redirect input and output
1589 for remote debugging.
1590

1592 a couple of issues, notably handling of long file names using the
1593 GNU LONGNAME extension.
1594
1595- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1596 new flag when ``name`` is already the name of an option flag.
1597
1598- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1599 package.
1600
1601- Patch #1472854: make the rlcompleter.Completer class usable on non-
1602 UNIX platforms.

1642Core and builtins
1643-----------------
1644
Thomas Heller1b046642006-04-18 18:51:06 +00001645- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1646 by converting these apis from macros into exported functions again:
1647
1648 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1649 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1650 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1651 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1652 PyRun_String Py_CompileString
1653
Martin v. Löwis45294a92006-04-18 06:24:08 +00001654- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1655
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001656- All uses of PyStructSequence_InitType have been changed to initialize
1657 the type objects only once, even if the interpreter is initialized
1658 multiple times.
1659
Neal Norwitz61546162006-04-14 05:20:28 +00001660- Bug #1454485, array.array('u') could crash the interpreter. This was
1661 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1662 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1663
1664- Py_UNICODE is unsigned. It was always documented as unsigned, but
1665 due to a bug had a signed value in previous versions.
1666
Tim Peters3a5e8b12006-04-11 01:44:07 +00001667- Patch #837242: ``id()`` of any Python object always gives a positive
1668 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1669 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001670 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001671 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001672
Tim Peters3a5e8b12006-04-11 01:44:07 +00001673 def __hash__(self):
1674 return id(self) # WRONG
1675
1676 because a hash result must be a (short) Python int but it was always
1677 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001678 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001679 was always usable as a hash value before this patch. That's no longer
1680 necessarily so.
1681
1682- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001683 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001684 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001685 #1454844)
1686
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001687- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1688 involving generators that have paused outside of any ``try`` or ``with``
1689 blocks. (In 2.5a1, a paused generator that was part of a reference
1690 cycle could not be garbage collected, regardless of whether it was
1691 paused in a ``try`` or ``with`` block.)

1721 abusing errno.
1722
Tim Peters711bf302006-04-25 03:31:36 +00001723- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1724 a doctest to be skipped (the code is not run, and the expected output
1725 or exception is ignored).
1726
Nick Coghlanda2268f2006-04-24 04:37:15 +00001727- Fixed contextlib.nested to cope with exceptions being raised and
1728 caught inside exit handlers.
1729
Greg Wardab05edc2006-04-23 03:47:58 +00001730- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1731 hex, octal, or binary; add ``append_const`` action; keep going if
1732 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1733 added ``epilog`` for better help generation).
1734
Tim Peters21fbd572006-04-21 21:18:10 +00001735- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1736 called from a thread spawned as a side effect of importing a module.
1737
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001738- The pydoc module now supports documenting packages contained in
1739 .zip or .egg files.
1740
1741- The pkgutil module now has several new utility functions, such
1742 as ``walk_packages()`` to support working with packages that are either
1743 in the filesystem or zip files.
1744
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001745- The mailbox module can now modify and delete messages from
1746 mailboxes, in addition to simply reading them. Thanks to Gregory
1747 K. Johnson for writing the code, and to the 2005 Google Summer of
1748 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001749
Tim Petersc7605f22006-04-17 21:12:33 +00001750- The ``__del__`` method of class ``local`` in module ``_threading_local``
1751 returned before accomplishing any of its intended cleanup.
1752
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001753- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001784- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001785
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001786- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1787 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001788 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001789 CXX from --with-cxx-main, see description in README.
1790
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001791- Patch #1429775: Link extension modules with the shared libpython.
1792
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001793- Fixed a libffi build problem on MIPS systems.
1794
Tim Peters8931ff12006-05-13 23:28:20 +00001795- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1796 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1797 and "%zu" for unsigned integers of type ``size_t``.
1798
Anthony Baxter51bcb682006-04-05 14:51:42 +00001799Tests
1800-----
1801
Nick Coghlanda2268f2006-04-24 04:37:15 +00001802- test_contextlib now checks contextlib.nested can cope with exceptions
1803 being raised and caught inside exit handlers.
1804
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001805- test_cmd_line now checks operation of the -m and -c command switches
1806
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001807- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1808 it separately and by hand. It also wasn't cleaning up its changes to
1809 the current Decimal context.
1810
Thomas Woutersabd08882006-04-26 15:53:30 +00001811- regrtest.py now has a -M option to run tests that test the new limits of
1812 containers, on 64-bit architectures. Running these tests is only sensible
1813 on 64-bit machines with more than two gigabytes of memory. The argument
1814 passed is the maximum amount of memory for the tests to use.
1815
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001816Tools
1817-----
1818
1819- Added the Python benchmark suite pybench to the Tools/ directory;
1820 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001822Documentation
1823-------------
1824
Tim Petersb06d28c2006-05-12 01:57:59 +00001825- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1826
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001827- PEP 343: Added Context Types section to the library reference
1828 and attempted to bring other PEP 343 related documentation into
1829 line with the implementation and/or python-dev discussions.
1830
Tim Peters8dc73d22006-04-24 02:03:16 +00001831- Bug #1337990: clarified that ``doctest`` does not support examples
1832 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001835What's New in Python 2.5 alpha 1?
1836=================================
1837
Anthony Baxterebed3f62006-04-03 15:03:44 +00001838*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001839
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001840Core and builtins
1841-----------------
1842
Nick Coghlan43832302006-04-23 17:04:07 +00001843- PEP 338: -m command line switch now delegates to runpy.run_module
1844 allowing it to support modules in packages and zipfiles
1845
Martin v. Löwisc661b882006-04-20 04:54:23 +00001846- On Windows, .DLL is not an accepted file name extension for
1847 extension modules anymore; extensions are only found if they
1848 end in .PYD.
1849
Martin v. Löwisea62d252006-04-03 10:56:49 +00001850- Bug #1421664: sys.stderr.encoding is now set to the same value as
1851 sys.stdout.encoding.
1852
Neal Norwitz92e212f2006-04-03 04:48:37 +00001853- __import__ accepts keyword arguments.
1854
Georg Brandlccadf842006-03-31 18:54:53 +00001855- Patch #1460496: round() now accepts keyword arguments.
1856
Anthony Baxter262c00a2006-03-30 10:53:17 +00001857- Fixed bug #1459029 - unicode reprs were double-escaped.
1858
Hye-Shik Changd478f342006-03-23 12:32:36 +00001859- Patch #1396919: The system scope threads are reenabled on FreeBSD
1860 5.4 and later versions.
1861
Neal Norwitze98ccf62006-03-23 05:39:47 +00001862- Bug #1115379: Compiling a Unicode string with an encoding declaration
1863 now gives a SyntaxError.
1864
Georg Brandlabd1ff82006-03-18 07:59:59 +00001865- Previously, Python code had no easy way to access the contents of a
1866 cell object. Now, a ``cell_contents`` attribute has been added
1867 (closes patch #1170323).
1868
Tim Peterscf79aac2006-03-16 01:14:46 +00001869- Patch #1123430: Python's small-object allocator now returns an arena to
1870 the system ``free()`` when all memory within an arena becomes unused
1871 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1872 freed. Some applications will see a drop in virtual memory size now,
1873 especially long-running applications that, from time to time, temporarily
1874 use a large number of small objects. Note that when Python returns an
1875 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001876 platform C library will in turn return that memory to the operating system.
1877 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001878 appears to be effective at least on Microsoft C and gcc-based systems.
1879 Thanks to Evan Jones for hard work and patience.
1880
Georg Brandl533ff6f2006-03-08 18:09:27 +00001881- Patch #1434038: property() now uses the getter's docstring if there is
1882 no "doc" argument given. This makes it possible to legitimately use
1883 property() as a decorator to produce a read-only property.
1884
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001885- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1886 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1887 of requiring an int or long in slicing and a few other contexts, enabling
1888 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1889
Neal Norwitz995acdf2006-03-07 05:01:00 +00001890- Fixed various bugs reported by Coverity's Prevent tool.
1891
Brett Cannonbf364092006-03-01 04:25:17 +00001892- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1893 new exception base class, BaseException, which has a new message attribute.
1894 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1895 Raising a string exception now raises a DeprecationWarning.
1896
Thomas Woutersfb609f42006-02-28 16:37:25 +00001897- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1898 explicitly relative, using 'from .module import name' to mean 'from the same
1899 package as this module is in. Imports without dots still default to the
1900 old relative-then-absolute, unless 'from __future__ import
1901 absolute_import' is used.
1902
Brett Cannona7446e32006-02-27 23:39:10 +00001903- Properly check if 'warnings' raises an exception (usually when a filter set
1904 to "error" is triggered) when raising a warning for raising string
1905 exceptions.
1906
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001907- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001908 The name was removed from Include/code.h.
1909
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001910- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001911
Guido van Rossum1968ad32006-02-25 22:38:04 +00001912- Patch 1433928:
1913 - The copy module now "copies" function objects (as atomic objects).
1914 - dict.__getitem__ now looks for a __missing__ hook before raising
1915 KeyError.
1916
Tim Peters84ef21c2006-02-28 20:39:06 +00001917- PEP 343: with statement implemented. Needs ``from __future__ import
1918 with_statement``. Use of 'with' as a variable will generate a warning.
1919 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001920 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001921 The following objects have __context__ methods:
1922 - The built-in file type.
1923 - The thread.LockType type.
1924 - The following types defined by the threading module:
1925 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1926 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001927
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001928- Fix the encodings package codec search function to only search
1929 inside its own package. Fixes problem reported in patch #1433198.
1930
1931 Note: Codec packages should implement and register their own
1932 codec search function. PEP 100 has the details.
1933
Tim Peters9ea89d22006-06-04 03:26:02 +00001934- PEP 353: Using ``Py_ssize_t`` as the index type.
1935
1936- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1937 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1938 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1939 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1940 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001941
Neal Norwitzfc76d632006-01-10 06:03:13 +00001942- Patch #1400181, fix unicode string formatting to not use the locale.
1943 This is how string objects work. u'%f' could use , instead of .
1944 for the decimal point. Now both strings and unicode always use periods.
1945
Neal Norwitz671b9e32006-01-09 07:07:12 +00001946- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1947 configure would break checking curses.h.
1948
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001949- Bug #959576: The pwd module is now builtin. This allows Python to be
1950 built on UNIX platforms without $HOME set.
1951
Neal Norwitzc10978f2005-12-19 06:07:16 +00001952- Bug #1072182, fix some potential problems if characters are signed.
1953
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001954- Bug #889500, fix line number on SyntaxWarning for global declarations.
1955
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001956- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1957
Neal Norwitze7214a12005-12-18 05:03:17 +00001958- Support for converting hex strings to floats no longer works.
1959 This was not portable. float('0x3') now raises a ValueError.
1960
Barry Warsaw2a38a862005-12-18 01:27:35 +00001961- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001962 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001963 is now displayed in interactive prompt banner.
1964
Georg Brandlfa166682005-12-17 21:45:17 +00001965- Implementation of PEP 341 - Unification of try/except and try/finally.
1966 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001967 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001968
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001969- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1970 now encodes backslash correctly.
1971
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001972- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1973
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001974- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001975 and long longs.
1976
Neal Norwitz67715f02005-11-09 06:59:35 +00001977- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001978 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001979 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001980
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001981- Replaced most Unicode charmap codecs with new ones using the
1982 new Unicode translate string feature in the builtin charmap
1983 codec; the codecs were created from the mapping tables available
1984 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1985 encodings now include a mapping for the Apple logo)
1986
Tim Peterse3547fd2005-12-16 23:13:57 +00001987- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001988
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001989- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001990
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001991- A new AST parser implementation was completed. The abstract
1992 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001993 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001994
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001995- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001996 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1997
Neal Norwitz708e51a2005-10-03 04:48:15 +00001998- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1999
Neal Norwitz11bd1192005-10-03 00:54:56 +00002000- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2001 Provide a warning when a directory is passed on the command line.
2002
Neal Norwitz40d37812005-10-02 01:48:49 +00002003- Fix segfault with invalid coding.
2004
2005- SF bug #772896: unknown encoding results in MemoryError.
2006
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002007- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002008 supported a __len__() method which evaluated to False when the iterator
2009 was empty.
2010
Guido van Rossum630db602005-09-20 18:49:54 +00002011- On 64-bit platforms, when __len__() returns a value that cannot be
2012 represented as a C int, raise OverflowError.
2013
Skip Montanarof8948ca2005-09-19 03:54:46 +00002014- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002015 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002016
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002017- SF bug #893549: parsing keyword arguments was broken with a few format
2018 codes.
2019
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002020- Changes donated by Elemental Security to make it work on AIX 5.3
2021 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2022 bug #105470: test_pwd fails on 64bit system (Opteron).
2023
Guido van Rossum539c6622005-09-14 17:49:54 +00002024- Changes donated by Elemental Security to make it work on HP-UX 11 on
2025 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2026
Georg Brandl4550b8d2005-08-26 06:43:52 +00002027- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002028 (fixes bug #1119418).
2029
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002030- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2031
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002032- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2033 exceptions that cause a function to exit.
2034
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002035- The implementation of set() and frozenset() was revised to use its
2036 own internal data structure. Memory consumption is reduced by 1/3
2037 and there are modest speed-ups as well. The API is unchanged.
2038
Tim Petersde7990b2005-07-17 23:45:23 +00002039- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2040
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002041- SF bug #1229429: PyObject_CallMethod failed to decrement some
2042 reference counts in some error exit cases.
2043
Tim Petersecc6e6a2005-07-10 22:30:55 +00002044- SF bug #1185883: Python's small-object memory allocator took over
2045 a block managed by the platform C library whenever a realloc specified
2046 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002047 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002048 portable way to copy data from the C-managed block into Python's
2049 small-object space without risking a memory fault. Python's small-object
2050 realloc now leaves such blocks under the control of the platform C
2051 realloc.
2052
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002053- SF bug #1232517: An overflow error was not detected properly when
2054 attempting to convert a large float to an int in os.utime().
2055
Raymond Hettinger3296e692005-06-29 23:29:56 +00002056- SF bug #1224347: hex longs now print with lowercase letters just
2057 like their int counterparts.
2058
Michael W. Hudson188d4362005-06-20 16:52:57 +00002059- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2060 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2061 interpreter states; back out that fix and do a better job (see
2062 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2063 for a longer write-up of the problem).
2064
Michael W. Hudsondf888462005-06-03 14:41:55 +00002065- SF patch #1180995: marshal now uses a binary format by default when
2066 serializing floats.
2067
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002068- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2069 the routines that promise to produce IEEE 754 binary representations
2070 of floats now simply copy bytes around.
2071
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002072- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2073 278.
2074
Brett Cannonc3647ac2005-04-26 03:45:26 +00002075- patch #1109424: int, long, float, complex, and unicode now check for the
2076 proper magic slot for type conversions when subclassed. Previously the
2077 magic slot was ignored during conversion. Semantics now match the way
2078 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002079 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002080 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002081 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002082
Barry Warsawc8d907c2005-04-19 23:43:40 +00002083- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2084 NULL, now raise an AttributeError when attempting to set or delete the
2085 attribute. Previously a TypeError was raised, but this was inconsistent
2086 with the equivalent pure-Python implementation.
2087
Michael W. Hudson774479c2005-04-18 08:46:17 +00002088- It is now safe to call PyGILState_Release() before
2089 PyEval_InitThreads() (note that if there is reason to believe there
2090 are multiple threads around you still must call PyEval_InitThreads()
2091 before using the Python API; this fix is for extension modules that
2092 have no way of knowing if Python is multi-threaded yet).
2093
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002094- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2095 disabled caused a crash.
2096
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002097- Bug #1165306: instancemethod_new allowed the creation of a method
2098 with im_class == im_self == NULL, which caused a crash when called.
2099
Tim Petersecc6e6a2005-07-10 22:30:55 +00002100- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002101 fixes the crash seen in bug #1165761
2102
Raymond Hettinger96229b12005-03-11 06:49:40 +00002103- Added two new builtins, any() and all().
2104
Brett Cannon409d8f22005-03-05 06:47:57 +00002105- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002106 (e.g., ``class C(): pass`` is no longer a syntax error).
2107 Patch #1176012 added support to the 'parser' module and 'compiler' package
2108 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002109
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002110- Patch #1115086: Support PY_LONGLONG in structmember.
2111
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002112- Bug #1155938: new style classes did not check that __init__() was
2113 returning None.
2114
Tim Petersecc6e6a2005-07-10 22:30:55 +00002115- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002116 ('\') with a specific error message.
2117
Martin v. Löwisff232d72005-03-03 09:24:38 +00002118- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2119
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002120- Bug #1124295: the __name__ attribute of file objects was
2121 inadvertently made inaccessible in restricted mode.
2122
Tim Petersecc6e6a2005-07-10 22:30:55 +00002123- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002124 an ferror() call.
2125
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002126- min() and max() now support key= arguments with the same meaning as in
2127 list.sort().
2128
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002129- The peephole optimizer now performs simple constant folding in expressions:
2130 (2+3) --> (5).
2131
Raymond Hettingera422c342005-01-11 03:03:27 +00002132- set and frozenset objects can now be marshalled. SF #1098985.
2133
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002134- Bug #1077106: Poor argument checking could cause memory corruption
2135 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002136
Jeremy Hyltonab630502005-02-04 18:44:06 +00002137- The parser did not complain about future statements in illegal
2138 positions. It once again reports a syntax error if a future
2139 statement occurs after anything other than a doc string.
2140
Neil Schemenauercf52c072005-08-12 17:34:58 +00002141- Change the %s format specifier for str objects so that it returns a
2142 unicode instance if the argument is not an instance of basestring and
2143 calling __str__ on the argument returns a unicode instance.
2144
Tim Petersf4e69282006-02-27 17:15:31 +00002145- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2146 current thread state when the auto-GIL-state machinery knows about
2147 it (since the thread state is being deleted, continuing to remember it
2148 can't help, but can hurt if another thread happens to get created with
2149 the same thread id).
2150
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002151Extension Modules

2168
2169- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2170
2171- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002172 is deprecated. The undocumented re.engine variable no longer exists.

2176
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002177- The unicodedata module was updated to the 4.1 version of the Unicode
2178 database. The 3.2 version is still available as unicodedata.db_3_2_0
2179 for applications that require this specific version (such as IDNA).
2180
Neal Norwitzb62c4332006-03-04 18:35:47 +00002181- The timing module is no longer built by default. It was deprecated

2202
Martin v. Löwis14694662006-02-03 12:54:16 +00002203- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2204 are reported, the limit on path name lengths is removed, and stat reports
2205 WindowsError now (instead of OSError).
2206

2282 the request code argument, which results in more C-like behaviour
2283 for large or negative values.
2284
Tim Petersecc6e6a2005-07-10 22:30:55 +00002285- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2327
Raymond Hettingerb2594052004-12-05 09:25:51 +00002328- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002341- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2342 been renamed to have only a single underscore prefix. This was done to
2343 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002344
Nick Coghlan43832302006-04-23 17:04:07 +00002345- PEP 338: new module runpy defines a run_module function to support
2346 executing modules which provide access to source code or a code object
2347 via the PEP 302 import mechanisms.
2348
Anthony Baxter93f5b932006-04-03 08:05:07 +00002349- The email module's parsedate_tz function now sets the daylight savings

2357 in attribute values.
2358
Anthony Baxterc51ee692006-04-01 00:57:31 +00002359- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002360 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002361 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002362 module will not be built.
2363
Tim Petersc17976e2006-04-01 00:26:53 +00002364- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2365 aren't officially supported here, and trying to use them will probably
2366 raise an exception some day. But dicts have been allowed, and "mostly
2367 worked", so support for them won't go away without warning.
2368
Georg Brandl338ef7d2006-03-31 18:42:16 +00002369- Bug #1445068: getpass.getpass() can now be given an explicit stream
2370 argument to specify where to write the prompt.
2371
Georg Brandl22ec80b2006-03-31 18:25:44 +00002372- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2381 to make it easier to monitor when daemon threads have completed
2382 processing all enqueued tasks. Patch #1455676.
2383
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002384- popen2.Popen objects now preserve the command in a .cmd attribute.

2387
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002388- email 4.0 package now integrated. This is largely the same as the email 3.0
2389 package that was included in Python 2.3, except that PEP 8 module names are
2390 now used (e.g. mail.message instead of email.Message). The MIME classes
2391 have been moved to a subpackage (e.g. email.mime.text instead of
2392 email.MIMEText). The old names are still supported for now. Several
2393 deprecated Message methods have been removed and lots of bugs have been
2394 fixed. More details can be found in the email package documentation.
2395
Walter Dörwald40108c92006-03-27 08:15:44 +00002396- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2397 (a subclass of tuple) that provides incremental decoders and encoders
2398 (a way to use stateful codecs without the stream API). Python functions
2399 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2400 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2401 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002402
Walter Dörwald067db482006-03-15 22:17:27 +00002403- Patch #1359365: Calling next() on a closed StringIO.String object raises
2404 a ValueError instead of a StopIteration now (like file and cString.String do).
2405 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2406 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002407
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002408- A regrtest option -w was added to re-run failed tests in verbose mode.

2481 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2482 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2483 Ronald L. Rivest offered this advice for Python:
2484
2485 "The consensus of researchers in this area (at least as
2486 expressed at the NIST Hash Function Workshop 10/31/05),
2487 is that SHA-256 is a good choice for the time being, but
2488 that research should continue, and other alternatives may
2489 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002490
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002491- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002575
Georg Brandl2f210b62005-06-26 22:09:06 +00002576- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2577
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002578- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2579 error messages.
2580
Georg Brandl379f99d2005-06-26 21:09:38 +00002581- Bug #1108948: Cookie.py produced invalid JavaScript code.
2582
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002583- The tokenize module now detects and reports indentation errors.
2584 Bug #1224621.
2585
Raymond Hettinger68c04532005-06-10 11:05:19 +00002586- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002587 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002588 the generate_tokens() function now accepts a callable argument that
2589 terminates by raising StopIteration.
2590
Georg Brandl9166e1a2005-06-04 09:20:03 +00002591- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2592
Georg Brandl268e61c2005-06-03 14:28:50 +00002593- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2594 component of the path.
2595
Skip Montanaro174dd222005-05-14 20:54:16 +00002596- Patch #1120353: The xmlrpclib module provides better, more transparent,
2597 support for datetime.{datetime,date,time} objects. With use_datetime set
2598 to True, applications shouldn't have to fiddle with the DateTime wrapper
2599 class at all.
2600
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002601- distutils.commands.upload was added to support uploading distribution
2602 files to PyPI.
2603
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002604- distutils.commands.register now encodes the data as UTF-8 before posting
2605 them to PyPI.
2606
Raymond Hettinger267b8682005-03-27 10:47:39 +00002607- decimal operator and comparison methods now return NotImplemented
2608 instead of raising a TypeError when interacting with other types. This
2609 allows other classes to implement __radd__ style methods and have them
2610 work as expected.
2611
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002612- Bug #1163325: Decimal infinities failed to hash. Attempting to
2613 hash a NaN raised an InvalidOperation instead of a TypeError.
2614
Tim Petersecc6e6a2005-07-10 22:30:55 +00002615- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002616 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2617
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002618- Patch #1043890: Add extractall method to tarfile.

2621 to build.
2622
Martin v. Löwis637431b2005-03-03 23:12:42 +00002623- Patch #1103407: Properly deal with tarfile iterators when untarring
2624 symbolic links on Windows.

2647
Raymond Hettingerbab41432005-02-05 01:31:19 +00002648- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2649
Guido van Rossumd0641422005-02-03 15:01:24 +00002650- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2651 disables recursive traversal through instance attributes, which can
2652 be exploited in various ways.
2653
Tim Peterse3547fd2005-12-16 23:13:57 +00002654- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002655 flags on the HTTP listening socket.
2656
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002657- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2658 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2659
Fred Drakefbdeaad2006-07-29 16:56:15 +00002660- Patches #893642, #1039083: add allow_none, encoding arguments to
2661 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002662
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002663- Bug #1110478: Revert os.environ.update to do putenv again.
2664
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002665- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2666
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002667- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2668
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002669- Enhancements to the csv module:
2670
2671 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002672 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002673 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002674 + Dialect parameter parsing has been re-implemented to improve error
2675 reporting.
2676 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2677 dictates.
2678 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002679 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002680 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002681 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2682 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002683 + reader now allows \r characters to be quoted (previously it only allowed
2684 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002685 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002686 + Dialect classes passed to the module are no longer instantiated by
2687 the module before being parsed (the former validation scheme required
2688 this, but the mechanism was unreliable).
2689 + The dialect registry now contains instances of the internal
2690 C-coded dialect type, rather than references to python objects.
2691 + the internal c-coded dialect type is now immutable.
2692 + register_dialect now accepts the same keyword dialect specifications
2693 as the reader and writer, allowing the user to register dialects
2694 without first creating a dialect class.
2695 + a configurable limit to the size of parsed fields has been added -
2696 previously, an unmatched quote character could result in the entire
2697 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002698 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002699 the parser field size limit (returning the former limit). The initial
2700 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002701 + A line_num attribute has been added to the reader object, which tracks
2702 the number of lines read from the source iterator. This is not
2703 the same as the number of records returned, as records can span
2704 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002705 + reader and writer objects were not being registered with the cyclic-GC.
2706 This has been fixed.
2707
Brett Cannone6539c42005-01-08 02:43:53 +00002708- _DummyThread objects in the threading module now delete self.__block that is
2709 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2710 lock primitives tend to be limited in number and thus should not be wasted on
2711 a _DummyThread object. Fixes bug #1089632.
2712
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002713- The imghdr module now detects Exif files.
2714
Raymond Hettinger6065d322004-12-20 23:51:53 +00002715- StringIO.truncate() now correctly adjusts the size attribute.
2716 (Bug #951915).
2717
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002718- locale.py now uses an updated locale alias table (built using
2719 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2720 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002721 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002722
Raymond Hettinger3557f422004-12-07 12:02:02 +00002723- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2724
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002725- the pickle module no longer accepts the deprecated None option in the
2726 args tuple returned by __reduce__().
2727
Brett Cannon84667c02004-12-07 03:25:18 +00002728- optparse now optionally imports gettext. This allows its use in setup.py.
2729
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002730- the pickle module no longer uses the deprecated bin parameter.
2731
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002732- the shelve module no longer uses the deprecated binary parameter.
2733
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002734- the pstats module no longer uses the deprecated ignore() method.
2735
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002736- the filecmp module no longer uses the deprecated use_statcache argument.
2737
Raymond Hettinger664347b2004-12-04 21:21:53 +00002738- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2739 extended or overridden by subclasses. Formerly, the subclassed method would
2740 be ignored by the rest of the module. (Bug #1078905).
2741
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002742- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002743 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002744
Walter Dörwald36733692004-12-22 12:50:50 +00002745- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2746 once when a size argument is given. This prevents a buffer overflow in the
2747 tokenizer with very long source lines.
2748
Barry Warsaw538561e2006-01-01 21:48:54 +00002749- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2750 immediately after creating the object, without any intervening
2751 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002752
Skip Montanaro05885812005-01-16 20:48:27 +00002753- The reconvert.quote function can now emit triple-quoted strings. The
2754 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002755
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002756- ``UserString.MutableString`` now supports negative indices in
2757 ``__setitem__`` and ``__delitem__``
2758
Greg Ward40407942005-03-05 02:53:17 +00002759- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2760 correctly.
2761
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002762- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2763 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2764 character even if the user has passed a size parameter to get a proper
2765 line ending. Remove the special handling of a "\r\n" that has been split
2766 between two lines.
2767
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002768- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2769 about illegal code points. The codec now supports PEP 293 style error
2770 handlers.
2771
Walter Dörwald78a78b02005-09-01 12:04:29 +00002772- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002773 from the input stream, so that the output is a byte string in the correct
2774 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002775
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002776- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2777 considering it exactly like a '*'.
2778
Walter Dörwald007f8df2005-10-09 19:42:27 +00002779- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2780 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002781
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002782- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2783
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002784- Patch #1413711: Certain patterns of differences were making difflib
2785 touch the recursion limit.
2786
Walter Dörwald58917a62006-03-31 15:26:22 +00002787- Bug #947906: An object oriented interface has been added to the calendar
2788 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002789 called as a script (e.g. via ``python -mcalendar``). Localized month and
2790 weekday names can be ouput (even if an exotic encoding is used) using
2791 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002792

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002807- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2808 The zlib module is now builtin on Windows.
2809
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002810- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2811
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002812- Bug #1189330: configure did not correctly determine the necessary
2813 value of LINKCC if python was built with GCC 4.0.
2814
Trent Mick8321b422005-07-26 02:29:21 +00002815- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2816 vulnerability in zlib 1.2.1 and 1.2.2.
2817
Brett Cannon08cd5982005-04-24 22:26:38 +00002818- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2819 flags that change binary compatibility. Changes were also made to
2820 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002821 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002822
Bob Ippolitoed233462005-03-29 13:47:59 +00002823- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2824 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2825 no longer exists). This configure patch makes things right.
2826
Martin v. Löwise2713be2005-03-08 15:03:08 +00002827- Bug #1158607: Build with --disable-unicode again.
2828
Brett Cannon46d96232005-02-16 00:07:19 +00002829- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2830 defined. Discovered as a result of not being able to build on OS X.
2831
Brett Cannon516592f2004-12-07 00:42:59 +00002832- setup.py now uses the directories specified in LDFLAGS using the -L option
2833 and in CPPFLAGS using the -I option for adding library and include
2834 directories, respectively, for compiling extension modules against. This has
2835 led to the core being compiled using the values in CPPFLAGS. It also removes
2836 the need for the special-casing of both DarwinPorts and Fink for darwin since
2837 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2838 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2839 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00002841- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2842 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2843 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2844 Closes bug #1096244. Thanks Gregory Bond.

2848
Tim Petersc9d78aa2006-03-26 23:27:58 +00002849- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2850 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2851 is obtained via the ``PyObject_`` family, it must be released via the
2852 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2853 always been officially true, but when Python's small-object allocator was
2854 introduced, an attempt was made to cater to a few extension modules
2855 discovered at the time that obtained memory via ``PyObject_New`` but
2856 released it via ``PyMem_DEL``. It's years later, and if such code still
2857 exists it will fail now (probably with segfaults, but calling wrong
2858 low-level memory management functions can yield many symptoms).
2859
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002860- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002864- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2865 mapping argument now. This string is used as a mapping table. Byte values
2866 greater than the length of the string and 0xFFFE are treated as undefined
2867 mappings.
