658-----------------
659
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000660- Make _PyGILState_NoteThreadState() static, it was not used anywhere
661 outside of pystate.c and should not be necessary.
662
Brett Cannon19d76c52006-09-09 07:18:44 +0000663- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
664 allows calling unicode() on exceptions classes directly to succeed.
665
Georg Brandlecab6232006-09-06 06:47:02 +0000666- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000681- The return tuple from str.rpartition(sep) is (tail, sep, head) where
682 head is the original string if sep was not found.
683
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000684- Bug #1520864: unpacking singleton tuples in list comprehensions and
685 generator expressions (x for x, in ... ) works again. Fixing this problem
686 required changing the .pyc magic number. This means that .pyc files
687 generated before 2.5c2 will be regenerated.

800-----------------
801
Neal Norwitz24b6f202006-09-05 04:43:56 +0000802- Fix infinite recursion when subclassing long and overriding __hash__.
803
804- Fix concatenation (+=) of long strings.
805
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000806- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000807 compared equal or unequal to a string and a UnicodeDecodeError
808 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000809
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000810 Instead, the equal (==) and unequal (!=) comparison operators will
811 now issue a UnicodeWarning and interpret the two objects as
812 unequal. The UnicodeWarning can be filtered as desired using
813 the warning framework, e.g. silenced completely, turned into an
814 exception, logged, etc.
815
816 Note that compare operators other than equal and unequal will still
817 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000818
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000819- Fix segfault when doing string formatting on subclasses of long.
820
821- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
822 with new-style classes.
823
824- Fix bug related to __len__ functions returning negative values with
825 classic classes.
826
827- Patch #1538606, Fix __index__() clipping. There were some problems
828 discovered with the API and how integers that didn't fit into Py_ssize_t
829 were handled. This patch attempts to provide enough alternatives
830 to effectively use __index__.
831
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000832- Bug #1536021: __hash__ may now return long int; the final hash
833 value is obtained by invoking hash on the long int.
834
Thomas Hellerab1049c2006-08-08 17:37:00 +0000835- Bug #1536786: buffer comparison could emit a RuntimeWarning.
836
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000837- Bug #1535165: fixed a segfault in input() and raw_input() when
838 sys.stdin is closed.
839
Thomas Heller74d36f02006-08-04 18:17:40 +0000840- On Windows, the PyErr_Warn function is now exported from
841 the Python dll again.
842
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000843- Bug #1191458: tracing over for loops now produces a line event
844 on each iteration. Fixing this problem required changing the .pyc
845 magic number. This means that .pyc files generated before 2.5c1
846 will be regenerated.
847
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000848- Bug #1333982: string/number constants were inappropriately stored
849 in the byte code and co_consts even if they were not used, ie
850 immediately popped off the stack.
851
Georg Brandle9462c72006-08-04 18:03:37 +0000852- Fixed a reference-counting problem in property().

856-------
857
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000858- Fix a bug in the ``compiler`` package that caused invalid code to be
859 generated for generator expressions.
860
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000861- The distutils version has been changed to 2.5.0. The change to
862 keep it programmatically in sync with the Python version running
863 the code (introduced in 2.5b3) has been reverted. It will continue
864 to be maintained manually as static string literal.
865
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000866- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000867 and this cannot be converted to the required C type, an exception is
868 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000869 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000870
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000871- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000872 an exception.
873
Tim Peterscbdd3502006-09-05 01:47:53 +0000874- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000875 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000876 workarounds for clocks with low resolution, to stop the code yielding
877 duplicate UUIDs.
878
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000879- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
880 before raising SystemExit, allowing IDLE to honor quit() and exit().
881
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000882- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
883
Georg Brandl7a1af772006-08-14 21:55:28 +0000884- Patch #1536071: trace.py should now find the full module name of a
885 file correctly even on Windows.
886
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000887- logging's atexit hook now runs even if the rest of the module has
888 already been cleaned up.
889

893 str(exception) raised an exception.
894
Neil Schemenauer06ded092006-08-04 16:20:30 +0000895- Fix a bug in the ``compiler`` package that caused invalid code to be

911
Thomas Heller86720042006-08-14 11:17:48 +0000912- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
913 uses the _as_parameter_ attribute when objects are passed to foreign

968Core and builtins
969-----------------
970
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000971- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000972 returned a long (see PEP 353).
973
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000974- Bug #1515471: string.replace() accepts character buffers again.
975
Neal Norwitz07aadb12006-07-30 06:55:48 +0000976- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
977 This provides the proper warning for struct.pack().
978 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
979
Neal Norwitz0d62a062006-07-30 06:53:31 +0000980- Patch #1531113: Fix augmented assignment with yield expressions.
981 Also fix a SystemError when trying to assign to yield expressions.
982
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000983- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
984 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
985 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
986 excessive filesystem operations during imports.
987
Tim Petersbc24eee2006-07-27 01:14:53 +0000988- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
989 operations on signed longs that are formally undefined by C.
990 Unfortunately, at least one compiler now cares about that, so complicated
991 the code to make that compiler happy again.
992
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000993- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
994
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000995- Patch #1232023: Stop including current directory in search
996 path on Windows.
997
Neal Norwitze1fdb322006-07-21 05:32:28 +0000998- Fix some potential crashes found with failmalloc.
999
Neal Norwitze7563102006-07-17 01:00:16 +00001000- Fix warnings reported by Klocwork's static analysis tool.
1001
Neal Norwitz84be93b2006-07-16 01:50:38 +00001002- Bug #1512814, Fix incorrect lineno's when code within a function
1003 had more than 255 blank lines.
1004
Georg Brandl9dceedb2006-07-12 15:31:17 +00001005- Patch #1521179: Python now accepts the standard options ``--help`` and
1006 ``--version`` as well as ``/?`` on Windows.
1007
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001008- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001009 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001010 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001011
Tim Peters112aad32006-07-19 00:03:19 +00001012- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001013 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001014 new ``sys._current_frames()`` returns a dictionary with one entry,
1015 mapping the faux "thread id" 0 to the current frame.
1016
Ronald Oussoren3075e162006-07-25 20:28:55 +00001017- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1021-------
1022
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001023- Correction of patch #1455898: In the mbcs decoder, set final=False
1024 for stream decoder, but final=True for the decode function.
1025
Georg Brandl07fec3a2006-08-01 18:49:24 +00001026- os.urandom no longer masks unrelated exceptions like SystemExit or
1027 KeyboardInterrupt.
1028
Tim Peters4643c2f2006-08-10 22:45:34 +00001029- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001030 shutil.copytree on Windows
1031
Georg Brandle34ac7c2006-07-30 11:07:23 +00001032- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1033 refers to file descriptors, not file objects.
1034
Tim Peterscbdd3502006-09-05 01:47:53 +00001035- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001036 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001037 #1513611, and probably others.
1038
Georg Brandledd9b0d2006-07-29 09:33:26 +00001039- Bug #1441397: The compiler module now recognizes module and function
1040 docstrings correctly as it did in Python 2.4.
1041
Tim Peters6f681472006-07-27 23:44:37 +00001042- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1043 lost that tests are sorted by name before being run. This rarely
1044 matters for well-written tests, but can create baffling symptoms if
1045 side effects from one test to the next affect outcomes. ``DocTestFinder``
1046 has been changed to sort the list of tests it returns.
1047
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001048- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001049 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001050
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001051- Bug #978833: Really close underlying socket in _socketobject.close.
1052
Georg Brandldb232dc2006-08-20 13:15:43 +00001053- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1054 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001055
Georg Brandlcf0c1722006-07-26 07:23:32 +00001056- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1057 to recursive calls and call it with the failing package name.
1058
Martin v. Löwis0b483032006-07-25 09:53:12 +00001059- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1060
Georg Brandlc13c34c2006-07-24 14:09:56 +00001061- Patch #1515343: Fix printing of deprecated string exceptions with a
1062 value in the traceback module.
1063
Greg Ward48fae7a2006-07-23 16:05:51 +00001064- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1065
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001066- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1067
Brett Cannoncaebe222006-07-18 04:41:36 +00001068- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1069 argument tuple. For arguments where zero is illegal, the value is forced to
1070 the minimum value that is correct. This is to support an undocumented but
1071 common way people used to fill in inconsequential information in the time
1072 tuple pre-2.4.
1073
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001074- Patch #1220874: Update the binhex module for Mach-O.
1075
Barry Warsawb110bad2006-07-21 14:51:07 +00001076- The email package has improved RFC 2231 support, specifically for
1077 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1078 (name*0=<blah>) parameter continuations. This may change the types of
1079 values returned from email.message.Message.get_param() and friends.
1080 Specifically in some cases where non-encoded continuations were used,
1081 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1082 will just return the string (since non-encoded continuations don't have
1083 charset and language parts).
1084
1085 Also, whereas % values were decoded in all parameter continuations, they are
1086 now only decoded in encoded parameter parts.
1087
Ronald Oussoren3075e162006-07-25 20:28:55 +00001088- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1089
1090- Bug #1517996: IDLE now longer shows the default Tk menu when a
1091 path browser, class browser or debugger is the frontmost window on MacOS X
1092
Barry Warsaw00decd72006-07-27 23:43:15 +00001093- Patch #1520294: Support for getset and member descriptors in types.py,
1094 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1095 of an object against these built-in types and more importantly, for getting
1096 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitz9b0ca792006-08-02 06:46:21 +00001102- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1103 a socket operation on a socket with a timeout, the exception will be
1104 caught correctly. Previously, the exception was not caught.
1105
Thomas Heller1393d6a2006-07-28 21:43:20 +00001106- Patch #1529514: The _ctypes extension is now compiled on more
1107 openbsd target platforms.
1108
Tim Peters9cab5932006-07-28 00:30:00 +00001109- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1110 a memory leak, affecting pickles and deep copies.
1111
Tim Petersbc24eee2006-07-27 01:14:53 +00001112- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1116
Thomas Hellerce049a02006-07-14 17:51:14 +00001117- Patch #1521817: Index range checking on ctypes arrays containing
1118 exactly one element enabled again. This allows iterating over these
1119 arrays, without the need to check the array size before.
1120
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001121- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001122 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001123 /dev/null in certain cases; this is now fixed.
1124
Thomas Heller47d7a062006-07-12 08:43:47 +00001125- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1126 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001127
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001128- Because of a misspelled preprocessor symbol, ctypes was always
1129 compiled without thread support; this is now fixed.
1130
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001131- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1132 methods now allow their database parameter to be None as the
1133 sleepycat API allows.
1134
Matt Flemingec926502006-07-28 11:27:27 +00001135- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1136 bluetooth API compared with Linux and FreeBSD.

1140
1141- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1142 how long the test file should take to play. Now accepts taking 2.93 secs
1143 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1144
Georg Brandl4793aa32006-07-28 18:31:39 +00001145- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1146 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1147 run via ``regrtest.py``. Now they do.

1158 characters that are treated specially by the shell (such as quotes).
1159
1160- Bug #1527397: PythonLauncher now launches scripts with the working directory
1161 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001162 directory. That latter was an implementation accident and not what users

1178 using augmented assignment is now correctly determined.
1179
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001180- Bug #927248: Recursive method-wrapper objects can now safely
1181 be released.
1182
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001183- Bug #1417699: Reject locale-specific decimal point in float()
1184 and atof().
1185
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001186- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1187 omit a default "error" argument for NULL pointer. This allows
1188 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001189
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001190- Bug #1519018: 'as' is now validated properly in import statements.
1191
Neal Norwitz28746ab2006-07-09 22:14:42 +00001192- On 64 bit systems, int literals that use less than 64 bits are
1193 now ints rather than longs.
1194
Neal Norwitzed657552006-07-10 00:04:44 +00001195- Bug #1512814, Fix incorrect lineno's when code at module scope
1196 started after line 256.
1197
Tim Peters32a83612006-07-10 21:08:24 +00001198- New function ``sys._current_frames()`` returns a dict mapping thread
1199 id to topmost thread stack frame. This is for expert use, and is
1200 especially useful for debugging application deadlocks. The functionality
1201 was previously available in Fazal Majid's ``threadframe`` extension
1202 module, but it wasn't possible to do this in a wholly threadsafe way from
1203 an extension.

1220
Thomas Woutersadd19112006-07-05 11:03:49 +00001221- string.Template() now correctly handles tuple-values. Previously,
1222 multi-value tuples would raise an exception and single-value tuples would
1223 be treated as the value they contain, instead.
1224
Martin v. Löwisede77f52006-07-03 13:01:35 +00001225- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1247 sgmllib ('[' and ']' were not accepted).
1248
Georg Brandl1be63af2006-06-28 20:23:25 +00001249- Fix a bug in the turtle module's end_fill function.
1250
Brett Cannon53ab5b72006-06-22 16:49:14 +00001251- Bug #1510580: The 'warnings' module improperly required that a Warning
1252 category be either a types.ClassType and a subclass of Warning. The proper
1253 check is just that it is a subclass with Warning as the documentation states.
1254
Georg Brandlad29e632006-06-21 17:45:17 +00001255- The compiler module now correctly compiles the new try-except-finally
1256 statement (bug #1509132).
1257
Neal Norwitz60373cd2006-06-22 06:30:50 +00001258- The wsgiref package is now installed properly on Unix.
1259
Vinay Sajip28e57612006-07-01 10:45:20 +00001260- A bug was fixed in logging.config.fileConfig() which caused a crash on
1261 shutdown when fileConfig() was called multiple times.
1262
Gerhard Häring762fbd32006-07-02 17:48:30 +00001263- The sqlite3 module did cut off data from the SQLite database at the first
1264 null character before sending it to a custom converter. This has been fixed
1265 now.
1266
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001267Extension Modules
1268-----------------
1269
Tim Peters112aad32006-07-19 00:03:19 +00001270- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1271 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1272 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001273
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001274- Assigning None to pointer type fields in ctypes structures possible
1275 overwrote the wrong fields, this is fixed now.
1276
1277- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1278 on non-Windows platforms.
1279
1280- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1281 integer or long, without range checking.
1282
1283- Patch #1517790: It is now possible to use custom objects in the ctypes
1284 foreign function argtypes sequence as long as they provide a from_param
1285 method, no longer is it required that the object is a ctypes type.
1286
1287- The '_ctypes' extension module now works when Python is configured
1288 with the --without-threads option.
1289
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001290- Bug #1513646: os.access on Windows now correctly determines write
1291 access, again.
1292
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001293- Bug #1512695: cPickle.loads could crash if it was interrupted with
1294 a KeyboardInterrupt.
1295
Neal Norwitza12aa882006-07-06 06:45:08 +00001296- Bug #1296433: parsing XML with a non-default encoding and
1297 a CharacterDataHandler could crash the interpreter in pyexpat.
1298
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001299- Patch #1516912: improve Modules support for OpenVMS.

1303
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001304- Automate Windows build process for the Win64 SSL module.
1305
Tim Peters32a83612006-07-10 21:08:24 +00001306- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001307 Previously, the slight difference could cause compilation errors of the
1308 'zlib' module on systems with more than one version of zlib.
1309
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001310- The MSI compileall step was fixed to also support a TARGETDIR
1311 with spaces in it.
1312
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001313- Bug #1517388: sqlite3.dll is now installed on Windows independent
1314 of Tcl/Tk.
1315
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001316- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001317 trying to be installed even though it's empty.

1341Core and builtins
1342-----------------
1343
Georg Brandla56b9152006-06-19 06:35:54 +00001344- Patch #1507676: Error messages returned by invalid abstract object operations
1345 (such as iterating over an integer) have been improved and now include the
1346 type of the offending object to help with debugging.
1347
Brett Cannonea3912b2006-06-13 21:46:41 +00001348- Bug #992017: A classic class that defined a __coerce__() method that returned
1349 its arguments swapped would infinitely recurse and segfault the interpreter.
1350
Neal Norwitz909eb122006-06-12 02:13:21 +00001351- Fix the socket tests so they can be run concurrently.
1352
Neal Norwitzb9845e72006-06-12 02:11:18 +00001353- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001354 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001355
Brett Cannon22565aa2006-06-09 22:31:23 +00001356- Bug #532646: object.__call__() will continue looking for the __call__
1357 attribute on objects until one without one is found. This leads to recursion
1358 when you take a class and set its __call__ attribute to an instance of the
1359 class. Originally fixed for classic classes, but this fix is for new-style.
1360 Removes the infinite_rec_3 crasher.
1361
Georg Brandl24250812006-06-09 18:45:48 +00001362- The string and unicode methods startswith() and endswith() now accept
1363 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1364
Brett Cannonde3b0522006-06-08 17:00:45 +00001365- Buffer objects, at the C level, never used the char buffer
1366 implementation even when the char buffer for the wrapped object was
1367 explicitly requested (originally returned the read or write buffer).
1368 Now a TypeError is raised if the char buffer is not present but is
1369 requested.
1370
Georg Brandlddbaa662006-06-04 21:56:52 +00001371- Patch #1346214: Statements like "if 0: suite" are now again optimized
1372 away like they were in Python 2.4.
1373
Georg Brandlb7c8f542006-05-27 12:30:25 +00001374- Builtin exceptions are now full-blown new-style classes instead of
1375 instances pretending to be classes, which speeds up exception handling
1376 by about 80% in comparison to 2.5a2.
1377
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001378- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1379 Unicode 4.1.
1380
Georg Brandlf4ef1162006-05-26 18:03:31 +00001381- Patch #921466: sys.path_importer_cache is now used to cache valid and
1382 invalid file paths for the built-in import machinery which leads to
1383 fewer open calls on startup.
1384
Tim Peters696cf432006-05-24 21:10:40 +00001385- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1386 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1387 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1388 the number of input digits (it was and remains linear-time for bases
1389 2, 4, 8, 16 and 32).
1390
Tim Petersb713ec22006-05-23 18:45:30 +00001391- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1392 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1393 an integer close to ``sys.maxint``. This was repaired by patch
1394 #1335972, which also gives a nice speedup.
1395
Richard Jonescebbefc2006-05-23 18:28:17 +00001396- Patch #1337051: reduced size of frame objects.
1397
1398- PyErr_NewException now accepts a tuple of base classes as its
1399 "base" parameter.
1400
Richard Jones7c88dcc2006-05-23 10:37:38 +00001401- Patch #876206: function call speedup by retaining allocated frame
1402 objects.
1403
Georg Brandl7b90e162006-05-18 07:01:27 +00001404- Bug #1462152: file() now checks more thoroughly for invalid mode
1405 strings and removes a possible "U" before passing the mode to the
1406 C library function.
1407
Neal Norwitz1004a532006-05-15 07:17:23 +00001408- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1409
Neal Norwitz373f0a72006-05-15 07:04:36 +00001410- Bug #1487966: Fix SystemError with conditional expression in assignment
1411
Martin v. Löwis879768d2006-05-11 13:28:43 +00001412- WindowsError now has two error code attributes: errno, which carries
1413 the error values from errno.h, and winerror, which carries the error
1414 values from winerror.h. Previous versions put the winerror.h values
1415 (from GetLastError()) into the errno attribute.
1416
Martin v. Löwis77736712006-05-04 05:51:03 +00001417- Patch #1475845: Raise IndentationError for unexpected indent.
1418
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001419- Patch #1479181: split open() and file() from being aliases for each other.
1420
Tim Peters44bd9862006-06-01 13:49:23 +00001421- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1422 methods were always silently ignored by dictionaries when comparing keys.
1423 They are now passed through (except when using the C API function
1424 ``PyDict_GetItem()``, whose semantics did not change).
1425
1426- Bug #1456209: In some obscure cases it was possible for a class with a
1427 custom ``__eq__()`` method to confuse dict internals when class instances
1428 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1429 No, you don't have any code that did this ;-)

1432-----------------
1433
Trent Mick960a3f82006-06-28 20:30:41 +00001434- Bug #1295808: expat symbols should be namespaced in pyexpat
1435
1436- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1437
Brett Cannon6ee7d012006-06-08 16:23:04 +00001438- Change binascii.hexlify to accept a read-only buffer instead of only a char
1439 buffer and actually follow its documentation.
1440
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001441- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1442
Nick Coghlanc649ec52006-05-29 12:43:05 +00001443- Patch #1478788 (modified version): The functional extension module has
1444 been renamed to _functools and a functools Python wrapper module added.
1445 This provides a home for additional function related utilities that are
1446 not specifically about functional programming. See PEP 309.
1447
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001448- Patch #1493701: performance enhancements for struct module.
1449
Georg Brandl378d5922006-05-17 14:26:50 +00001450- Patch #1490224: time.altzone is now set correctly on Cygwin.
1451
Georg Brandl8d3342b2006-05-16 07:38:27 +00001452- Patch #1435422: zlib's compress and decompress objects now have a
1453 copy() method.
1454
Andrew MacIntyre92913322006-06-13 15:04:24 +00001455- Patch #1454481: thread stack size is now tunable at runtime for thread
1456 enabled builds on Windows and systems with Posix threads support.
1457
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001458- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1459 (up to the system limit of 32K characters).
1460
1461- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1462 As a result, these functions now raise WindowsError instead of OSError.
1463
Tim Peters7a822da2006-05-25 21:50:17 +00001464- ``time.clock()`` on Win64 should use the high-performance Windows
1465 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1466 Windows platforms).
1467
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001468- Calling Tk_Init twice is refused if the first call failed as that
1469 may deadlock.
1470
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001471- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1472 accept it without potentially using an uninitialized pointer.

Gregory P. Smith372b5832006-06-05 18:48:21 +00001481- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1482 parameter is supplied. [SF pybsddb bug #1477863]
1483
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001484- bsddb: the __len__ method of a DB object has been fixed to return correct
1485 results. It could previously incorrectly return 0 in some cases.
1486 Fixes SF bug 1493322 (pybsddb bug 1184012).
1487
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001488- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1489 aborts the db transaction safely when a modifier callback fails.
1490 Fixes SF python patch/bug #1408584.

Gregory P. Smith506f7b52006-06-15 08:52:32 +00001492- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001493 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001494 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1495 database calls that would previously deadlock. [SF python bug #775414]

1526
Tim Peters43898b42006-06-14 04:09:25 +00001527- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1528 guarantee that adjacent triples in the return list always describe
1529 non-adjacent blocks. Previously, a pair of matching blocks could end
1530 up being described by multiple adjacent triples that formed a partition
1531 of the matching pair.

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001541- The wsgiref package has been added to the standard library.
1542
Nick Coghlan676725d2006-06-08 13:54:49 +00001543- The functions update_wrapper() and wraps() have been added to the functools
1544 module. These make it easier to copy relevant metadata from the original
1545 function when writing wrapper functions.
1546
Tim Petersd6a9eef2006-06-05 01:48:21 +00001547- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1548 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001549
Martin v. Löwis3f767792006-06-04 19:36:28 +00001550- Patch #1359618: Speed up charmap encoder by using a trie structure
1551 for lookup.
1552
Tim Petersd609b1a2006-06-02 23:22:51 +00001553- The functions in the ``pprint`` module now sort dictionaries by key
1554 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1555 if and only if its display required more than one line, although that
1556 wasn't documented. The new behavior increases predictability; e.g.,
1557 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

1578
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001579- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1580 stdout arguments, making it possible to redirect input and output
1581 for remote debugging.
1582
1583- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1584 a couple of issues, notably handling of long file names using the
1585 GNU LONGNAME extension.
1586
1587- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1588 new flag when ``name`` is already the name of an option flag.
1589
1590- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1591 package.
1592
1593- Patch #1472854: make the rlcompleter.Completer class usable on non-
1594 UNIX platforms.

1634Core and builtins
1635-----------------
1636
Thomas Heller1b046642006-04-18 18:51:06 +00001637- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1638 by converting these apis from macros into exported functions again:
1639
1640 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1641 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1642 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1643 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1644 PyRun_String Py_CompileString
1645
Martin v. Löwis45294a92006-04-18 06:24:08 +00001646- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1647
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001648- All uses of PyStructSequence_InitType have been changed to initialize
1649 the type objects only once, even if the interpreter is initialized
1650 multiple times.
1651
Neal Norwitz61546162006-04-14 05:20:28 +00001652- Bug #1454485, array.array('u') could crash the interpreter. This was
1653 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1654 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1655
1656- Py_UNICODE is unsigned. It was always documented as unsigned, but
1657 due to a bug had a signed value in previous versions.
1658
Tim Peters3a5e8b12006-04-11 01:44:07 +00001659- Patch #837242: ``id()`` of any Python object always gives a positive
1660 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1661 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001662 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001663 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001664
Tim Peters3a5e8b12006-04-11 01:44:07 +00001665 def __hash__(self):
1666 return id(self) # WRONG
1667
1668 because a hash result must be a (short) Python int but it was always
1669 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001670 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001671 was always usable as a hash value before this patch. That's no longer
1672 necessarily so.
1673
1674- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001675 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001676 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001677 #1454844)
1678
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001679- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1680 involving generators that have paused outside of any ``try`` or ``with``
1681 blocks. (In 2.5a1, a paused generator that was part of a reference
1682 cycle could not be garbage collected, regardless of whether it was
1683 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001715- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

1717 or exception is ignored).
1718
Nick Coghlanda2268f2006-04-24 04:37:15 +00001719- Fixed contextlib.nested to cope with exceptions being raised and
1720 caught inside exit handlers.
1721
Greg Wardab05edc2006-04-23 03:47:58 +00001722- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1723 hex, octal, or binary; add ``append_const`` action; keep going if
1724 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1725 added ``epilog`` for better help generation).
1726
Tim Peters21fbd572006-04-21 21:18:10 +00001727- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1728 called from a thread spawned as a side effect of importing a module.
1729
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001730- The pydoc module now supports documenting packages contained in
1731 .zip or .egg files.
1732
1733- The pkgutil module now has several new utility functions, such
1734 as ``walk_packages()`` to support working with packages that are either
1735 in the filesystem or zip files.
1736
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001737- The mailbox module can now modify and delete messages from
1738 mailboxes, in addition to simply reading them. Thanks to Gregory
1739 K. Johnson for writing the code, and to the 2005 Google Summer of
1740 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001741
Tim Petersc7605f22006-04-17 21:12:33 +00001742- The ``__del__`` method of class ``local`` in module ``_threading_local``
1743 returned before accomplishing any of its intended cleanup.
1744
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001745- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001778- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1779 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001780 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001781 CXX from --with-cxx-main, see description in README.
1782
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001783- Patch #1429775: Link extension modules with the shared libpython.
1784
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001785- Fixed a libffi build problem on MIPS systems.
1786
Tim Peters8931ff12006-05-13 23:28:20 +00001787- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1788 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1789 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001791Tests
1792-----
1793
Nick Coghlanda2268f2006-04-24 04:37:15 +00001794- test_contextlib now checks contextlib.nested can cope with exceptions
1795 being raised and caught inside exit handlers.
1796
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001797- test_cmd_line now checks operation of the -m and -c command switches
1798
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001799- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1800 it separately and by hand. It also wasn't cleaning up its changes to
1801 the current Decimal context.
1802
Thomas Woutersabd08882006-04-26 15:53:30 +00001803- regrtest.py now has a -M option to run tests that test the new limits of
1804 containers, on 64-bit architectures. Running these tests is only sensible
1805 on 64-bit machines with more than two gigabytes of memory. The argument
1806 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001814Documentation
1815-------------
1816
Tim Petersb06d28c2006-05-12 01:57:59 +00001817- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1818
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001819- PEP 343: Added Context Types section to the library reference
1820 and attempted to bring other PEP 343 related documentation into
1821 line with the implementation and/or python-dev discussions.
1822
Tim Peters8dc73d22006-04-24 02:03:16 +00001823- Bug #1337990: clarified that ``doctest`` does not support examples
1824 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001827What's New in Python 2.5 alpha 1?
1828=================================
1829
Anthony Baxterebed3f62006-04-03 15:03:44 +00001830*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001831
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001832Core and builtins
1833-----------------
1834
Nick Coghlan43832302006-04-23 17:04:07 +00001835- PEP 338: -m command line switch now delegates to runpy.run_module
1836 allowing it to support modules in packages and zipfiles
1837
Martin v. Löwisc661b882006-04-20 04:54:23 +00001838- On Windows, .DLL is not an accepted file name extension for
1839 extension modules anymore; extensions are only found if they
1840 end in .PYD.
1841
Martin v. Löwisea62d252006-04-03 10:56:49 +00001842- Bug #1421664: sys.stderr.encoding is now set to the same value as
1843 sys.stdout.encoding.
1844
Neal Norwitz92e212f2006-04-03 04:48:37 +00001845- __import__ accepts keyword arguments.
1846
Georg Brandlccadf842006-03-31 18:54:53 +00001847- Patch #1460496: round() now accepts keyword arguments.
1848
Anthony Baxter262c00a2006-03-30 10:53:17 +00001849- Fixed bug #1459029 - unicode reprs were double-escaped.
1850
Hye-Shik Changd478f342006-03-23 12:32:36 +00001851- Patch #1396919: The system scope threads are reenabled on FreeBSD
1852 5.4 and later versions.
1853
Neal Norwitze98ccf62006-03-23 05:39:47 +00001854- Bug #1115379: Compiling a Unicode string with an encoding declaration
1855 now gives a SyntaxError.
1856
Georg Brandlabd1ff82006-03-18 07:59:59 +00001857- Previously, Python code had no easy way to access the contents of a
1858 cell object. Now, a ``cell_contents`` attribute has been added
1859 (closes patch #1170323).
1860
Tim Peterscf79aac2006-03-16 01:14:46 +00001861- Patch #1123430: Python's small-object allocator now returns an arena to
1862 the system ``free()`` when all memory within an arena becomes unused
1863 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1864 freed. Some applications will see a drop in virtual memory size now,
1865 especially long-running applications that, from time to time, temporarily
1866 use a large number of small objects. Note that when Python returns an
1867 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001868 platform C library will in turn return that memory to the operating system.
1869 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001870 appears to be effective at least on Microsoft C and gcc-based systems.
1871 Thanks to Evan Jones for hard work and patience.
1872
Georg Brandl533ff6f2006-03-08 18:09:27 +00001873- Patch #1434038: property() now uses the getter's docstring if there is
1874 no "doc" argument given. This makes it possible to legitimately use
1875 property() as a decorator to produce a read-only property.
1876
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001877- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1878 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1879 of requiring an int or long in slicing and a few other contexts, enabling
1880 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1881
Neal Norwitz995acdf2006-03-07 05:01:00 +00001882- Fixed various bugs reported by Coverity's Prevent tool.
1883
Brett Cannonbf364092006-03-01 04:25:17 +00001884- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1885 new exception base class, BaseException, which has a new message attribute.
1886 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1887 Raising a string exception now raises a DeprecationWarning.
1888
Thomas Woutersfb609f42006-02-28 16:37:25 +00001889- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1890 explicitly relative, using 'from .module import name' to mean 'from the same
1891 package as this module is in. Imports without dots still default to the
1892 old relative-then-absolute, unless 'from __future__ import
1893 absolute_import' is used.
1894
Brett Cannona7446e32006-02-27 23:39:10 +00001895- Properly check if 'warnings' raises an exception (usually when a filter set
1896 to "error" is triggered) when raising a warning for raising string
1897 exceptions.
1898
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001899- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001900 The name was removed from Include/code.h.
1901
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001902- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001903
Guido van Rossum1968ad32006-02-25 22:38:04 +00001904- Patch 1433928:
1905 - The copy module now "copies" function objects (as atomic objects).
1906 - dict.__getitem__ now looks for a __missing__ hook before raising
1907 KeyError.
1908
Tim Peters84ef21c2006-02-28 20:39:06 +00001909- PEP 343: with statement implemented. Needs ``from __future__ import
1910 with_statement``. Use of 'with' as a variable will generate a warning.
1911 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001912 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001913 The following objects have __context__ methods:
1914 - The built-in file type.
1915 - The thread.LockType type.
1916 - The following types defined by the threading module:
1917 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1918 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001919
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001920- Fix the encodings package codec search function to only search
1921 inside its own package. Fixes problem reported in patch #1433198.
1922
1923 Note: Codec packages should implement and register their own
1924 codec search function. PEP 100 has the details.
1925
Tim Peters9ea89d22006-06-04 03:26:02 +00001926- PEP 353: Using ``Py_ssize_t`` as the index type.
1927
1928- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1929 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1930 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1931 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1932 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001933
Neal Norwitzfc76d632006-01-10 06:03:13 +00001934- Patch #1400181, fix unicode string formatting to not use the locale.
1935 This is how string objects work. u'%f' could use , instead of .
1936 for the decimal point. Now both strings and unicode always use periods.
1937
Neal Norwitz671b9e32006-01-09 07:07:12 +00001938- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1939 configure would break checking curses.h.
1940
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001941- Bug #959576: The pwd module is now builtin. This allows Python to be
1942 built on UNIX platforms without $HOME set.
1943
Neal Norwitzc10978f2005-12-19 06:07:16 +00001944- Bug #1072182, fix some potential problems if characters are signed.
1945
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001946- Bug #889500, fix line number on SyntaxWarning for global declarations.
1947
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001948- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1949
Neal Norwitze7214a12005-12-18 05:03:17 +00001950- Support for converting hex strings to floats no longer works.
1951 This was not portable. float('0x3') now raises a ValueError.
1952
Barry Warsaw2a38a862005-12-18 01:27:35 +00001953- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001954 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001955 is now displayed in interactive prompt banner.
1956
Georg Brandlfa166682005-12-17 21:45:17 +00001957- Implementation of PEP 341 - Unification of try/except and try/finally.
1958 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001959 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001960
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001961- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1962 now encodes backslash correctly.
1963
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001964- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1965
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001966- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001967 and long longs.
1968
Neal Norwitz67715f02005-11-09 06:59:35 +00001969- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001970 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001971 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001972
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001973- Replaced most Unicode charmap codecs with new ones using the
1974 new Unicode translate string feature in the builtin charmap
1975 codec; the codecs were created from the mapping tables available
1976 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1977 encodings now include a mapping for the Apple logo)
1978
Tim Peterse3547fd2005-12-16 23:13:57 +00001979- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001980
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001981- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001982
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001983- A new AST parser implementation was completed. The abstract
1984 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001985 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001986
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001987- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001988 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1989
Neal Norwitz708e51a2005-10-03 04:48:15 +00001990- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1991
Neal Norwitz11bd1192005-10-03 00:54:56 +00001992- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1993 Provide a warning when a directory is passed on the command line.
1994
Neal Norwitz40d37812005-10-02 01:48:49 +00001995- Fix segfault with invalid coding.
1996
1997- SF bug #772896: unknown encoding results in MemoryError.
1998
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001999- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002000 supported a __len__() method which evaluated to False when the iterator
2001 was empty.
2002
Guido van Rossum630db602005-09-20 18:49:54 +00002003- On 64-bit platforms, when __len__() returns a value that cannot be
2004 represented as a C int, raise OverflowError.
2005
Skip Montanarof8948ca2005-09-19 03:54:46 +00002006- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002007 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002008
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002009- SF bug #893549: parsing keyword arguments was broken with a few format
2010 codes.
2011
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002012- Changes donated by Elemental Security to make it work on AIX 5.3
2013 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2014 bug #105470: test_pwd fails on 64bit system (Opteron).
2015
Guido van Rossum539c6622005-09-14 17:49:54 +00002016- Changes donated by Elemental Security to make it work on HP-UX 11 on
2017 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2018
Georg Brandl4550b8d2005-08-26 06:43:52 +00002019- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002020 (fixes bug #1119418).
2021
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002022- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2023
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002024- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2025 exceptions that cause a function to exit.
2026
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002027- The implementation of set() and frozenset() was revised to use its
2028 own internal data structure. Memory consumption is reduced by 1/3
2029 and there are modest speed-ups as well. The API is unchanged.
2030
Tim Petersde7990b2005-07-17 23:45:23 +00002031- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2032
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002033- SF bug #1229429: PyObject_CallMethod failed to decrement some
2034 reference counts in some error exit cases.
2035
Tim Petersecc6e6a2005-07-10 22:30:55 +00002036- SF bug #1185883: Python's small-object memory allocator took over
2037 a block managed by the platform C library whenever a realloc specified
2038 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002039 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002040 portable way to copy data from the C-managed block into Python's
2041 small-object space without risking a memory fault. Python's small-object
2042 realloc now leaves such blocks under the control of the platform C

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002045- SF bug #1232517: An overflow error was not detected properly when
2046 attempting to convert a large float to an int in os.utime().
2047
Raymond Hettinger3296e692005-06-29 23:29:56 +00002048- SF bug #1224347: hex longs now print with lowercase letters just
2049 like their int counterparts.
2050
Michael W. Hudson188d4362005-06-20 16:52:57 +00002051- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2052 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2053 interpreter states; back out that fix and do a better job (see
2054 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2055 for a longer write-up of the problem).
2056
Michael W. Hudsondf888462005-06-03 14:41:55 +00002057- SF patch #1180995: marshal now uses a binary format by default when
2058 serializing floats.
2059
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002060- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2061 the routines that promise to produce IEEE 754 binary representations
2062 of floats now simply copy bytes around.
2063
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002064- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2065 278.
2066
Brett Cannonc3647ac2005-04-26 03:45:26 +00002067- patch #1109424: int, long, float, complex, and unicode now check for the
2068 proper magic slot for type conversions when subclassed. Previously the
2069 magic slot was ignored during conversion. Semantics now match the way
2070 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002071 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002072 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002073 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002074
Barry Warsawc8d907c2005-04-19 23:43:40 +00002075- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2076 NULL, now raise an AttributeError when attempting to set or delete the
2077 attribute. Previously a TypeError was raised, but this was inconsistent
2078 with the equivalent pure-Python implementation.
2079
Michael W. Hudson774479c2005-04-18 08:46:17 +00002080- It is now safe to call PyGILState_Release() before
2081 PyEval_InitThreads() (note that if there is reason to believe there
2082 are multiple threads around you still must call PyEval_InitThreads()
2083 before using the Python API; this fix is for extension modules that
2084 have no way of knowing if Python is multi-threaded yet).
2085
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002086- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2087 disabled caused a crash.
2088
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002089- Bug #1165306: instancemethod_new allowed the creation of a method
2090 with im_class == im_self == NULL, which caused a crash when called.
2091
Tim Petersecc6e6a2005-07-10 22:30:55 +00002092- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002093 fixes the crash seen in bug #1165761
2094
Raymond Hettinger96229b12005-03-11 06:49:40 +00002095- Added two new builtins, any() and all().
2096
Brett Cannon409d8f22005-03-05 06:47:57 +00002097- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002098 (e.g., ``class C(): pass`` is no longer a syntax error).
2099 Patch #1176012 added support to the 'parser' module and 'compiler' package
2100 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002101
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002102- Patch #1115086: Support PY_LONGLONG in structmember.
2103
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002104- Bug #1155938: new style classes did not check that __init__() was
2105 returning None.
2106
Tim Petersecc6e6a2005-07-10 22:30:55 +00002107- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002108 ('\') with a specific error message.
2109
Martin v. Löwisff232d72005-03-03 09:24:38 +00002110- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2111
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002112- Bug #1124295: the __name__ attribute of file objects was
2113 inadvertently made inaccessible in restricted mode.
2114
Tim Petersecc6e6a2005-07-10 22:30:55 +00002115- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002116 an ferror() call.
2117
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002118- min() and max() now support key= arguments with the same meaning as in
2119 list.sort().
2120
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002121- The peephole optimizer now performs simple constant folding in expressions:
2122 (2+3) --> (5).
2123
Raymond Hettingera422c342005-01-11 03:03:27 +00002124- set and frozenset objects can now be marshalled. SF #1098985.
2125
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002126- Bug #1077106: Poor argument checking could cause memory corruption
2127 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002128
Jeremy Hyltonab630502005-02-04 18:44:06 +00002129- The parser did not complain about future statements in illegal
2130 positions. It once again reports a syntax error if a future
2131 statement occurs after anything other than a doc string.
2132
Neil Schemenauercf52c072005-08-12 17:34:58 +00002133- Change the %s format specifier for str objects so that it returns a
2134 unicode instance if the argument is not an instance of basestring and
2135 calling __str__ on the argument returns a unicode instance.
2136
Tim Petersf4e69282006-02-27 17:15:31 +00002137- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2138 current thread state when the auto-GIL-state machinery knows about
2139 it (since the thread state is being deleted, continuing to remember it
2140 can't help, but can hurt if another thread happens to get created with
2141 the same thread id).
2142

2168
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002169- The unicodedata module was updated to the 4.1 version of the Unicode
2170 database. The 3.2 version is still available as unicodedata.db_3_2_0
2171 for applications that require this specific version (such as IDNA).
2172
Neal Norwitzb62c4332006-03-04 18:35:47 +00002173- The timing module is no longer built by default. It was deprecated

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002317- the cPickle module no longer accepts the deprecated None option in the
2318 args tuple returned by __reduce__().
2319
Raymond Hettingerb2594052004-12-05 09:25:51 +00002320- itertools.islice() now accepts None for the start and step arguments.
2321 This allows islice() to work more readily with slices:
2322 islice(s.start, s.stop, s.step)
2323
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002324- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002333- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2334 been renamed to have only a single underscore prefix. This was done to
2335 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002336
Nick Coghlan43832302006-04-23 17:04:07 +00002337- PEP 338: new module runpy defines a run_module function to support
2338 executing modules which provide access to source code or a code object
2339 via the PEP 302 import mechanisms.
2340
Anthony Baxter93f5b932006-04-03 08:05:07 +00002341- The email module's parsedate_tz function now sets the daylight savings

2349 in attribute values.
2350
Anthony Baxterc51ee692006-04-01 00:57:31 +00002351- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002352 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002353 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002354 module will not be built.
2355
Tim Petersc17976e2006-04-01 00:26:53 +00002356- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2357 aren't officially supported here, and trying to use them will probably
2358 raise an exception some day. But dicts have been allowed, and "mostly
2359 worked", so support for them won't go away without warning.
2360
Georg Brandl338ef7d2006-03-31 18:42:16 +00002361- Bug #1445068: getpass.getpass() can now be given an explicit stream
2362 argument to specify where to write the prompt.
2363
Georg Brandl22ec80b2006-03-31 18:25:44 +00002364- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2373 to make it easier to monitor when daemon threads have completed
2374 processing all enqueued tasks. Patch #1455676.
2375
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002376- popen2.Popen objects now preserve the command in a .cmd attribute.

2379
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002380- email 4.0 package now integrated. This is largely the same as the email 3.0
2381 package that was included in Python 2.3, except that PEP 8 module names are
2382 now used (e.g. mail.message instead of email.Message). The MIME classes
2383 have been moved to a subpackage (e.g. email.mime.text instead of
2384 email.MIMEText). The old names are still supported for now. Several
2385 deprecated Message methods have been removed and lots of bugs have been
2386 fixed. More details can be found in the email package documentation.
2387
Walter Dörwald40108c92006-03-27 08:15:44 +00002388- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2389 (a subclass of tuple) that provides incremental decoders and encoders
2390 (a way to use stateful codecs without the stream API). Python functions
2391 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2392 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2393 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002394
Walter Dörwald067db482006-03-15 22:17:27 +00002395- Patch #1359365: Calling next() on a closed StringIO.String object raises
2396 a ValueError instead of a StopIteration now (like file and cString.String do).
2397 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2398 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002399
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002400- A regrtest option -w was added to re-run failed tests in verbose mode.

2473 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2474 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2475 Ronald L. Rivest offered this advice for Python:
2476
2477 "The consensus of researchers in this area (at least as
2478 expressed at the NIST Hash Function Workshop 10/31/05),
2479 is that SHA-256 is a good choice for the time being, but
2480 that research should continue, and other alternatives may
2481 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002482
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002483- Added a subset of Fredrik Lundh's ElementTree package. Available

2576 Bug #1224621.
2577
Raymond Hettinger68c04532005-06-10 11:05:19 +00002578- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002579 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002580 the generate_tokens() function now accepts a callable argument that
2581 terminates by raising StopIteration.

2587
Skip Montanaro174dd222005-05-14 20:54:16 +00002588- Patch #1120353: The xmlrpclib module provides better, more transparent,
2589 support for datetime.{datetime,date,time} objects. With use_datetime set
2590 to True, applications shouldn't have to fiddle with the DateTime wrapper
2591 class at all.
2592
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002593- distutils.commands.upload was added to support uploading distribution
2594 files to PyPI.
2595
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002596- distutils.commands.register now encodes the data as UTF-8 before posting
2597 them to PyPI.
2598
Raymond Hettinger267b8682005-03-27 10:47:39 +00002599- decimal operator and comparison methods now return NotImplemented
2600 instead of raising a TypeError when interacting with other types. This
2601 allows other classes to implement __radd__ style methods and have them
2602 work as expected.
2603
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002604- Bug #1163325: Decimal infinities failed to hash. Attempting to

2641
Guido van Rossumd0641422005-02-03 15:01:24 +00002642- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2643 disables recursive traversal through instance attributes, which can
2644 be exploited in various ways.
2645
Tim Peterse3547fd2005-12-16 23:13:57 +00002646- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002647 flags on the HTTP listening socket.
2648
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002649- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2650 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2651
Fred Drakefbdeaad2006-07-29 16:56:15 +00002652- Patches #893642, #1039083: add allow_none, encoding arguments to

2660
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002661- Enhancements to the csv module:
2662
2663 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002664 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002665 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002666 + Dialect parameter parsing has been re-implemented to improve error
2667 reporting.
2668 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2669 dictates.
2670 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002671 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002672 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002673 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2674 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002675 + reader now allows \r characters to be quoted (previously it only allowed
2676 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002677 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002678 + Dialect classes passed to the module are no longer instantiated by
2679 the module before being parsed (the former validation scheme required
2680 this, but the mechanism was unreliable).
2681 + The dialect registry now contains instances of the internal
2682 C-coded dialect type, rather than references to python objects.
2683 + the internal c-coded dialect type is now immutable.
2684 + register_dialect now accepts the same keyword dialect specifications
2685 as the reader and writer, allowing the user to register dialects
2686 without first creating a dialect class.
2687 + a configurable limit to the size of parsed fields has been added -
2688 previously, an unmatched quote character could result in the entire
2689 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002690 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002691 the parser field size limit (returning the former limit). The initial
2692 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002693 + A line_num attribute has been added to the reader object, which tracks
2694 the number of lines read from the source iterator. This is not
2695 the same as the number of records returned, as records can span
2696 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002697 + reader and writer objects were not being registered with the cyclic-GC.
2698 This has been fixed.
2699
Brett Cannone6539c42005-01-08 02:43:53 +00002700- _DummyThread objects in the threading module now delete self.__block that is
2701 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2702 lock primitives tend to be limited in number and thus should not be wasted on
2703 a _DummyThread object. Fixes bug #1089632.
2704
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002705- The imghdr module now detects Exif files.
2706
Raymond Hettinger6065d322004-12-20 23:51:53 +00002707- StringIO.truncate() now correctly adjusts the size attribute.
2708 (Bug #951915).
2709
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002710- locale.py now uses an updated locale alias table (built using
2711 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2712 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002713 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002714
Raymond Hettinger3557f422004-12-07 12:02:02 +00002715- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2716
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002717- the pickle module no longer accepts the deprecated None option in the
2718 args tuple returned by __reduce__().
2719
Brett Cannon84667c02004-12-07 03:25:18 +00002720- optparse now optionally imports gettext. This allows its use in setup.py.
2721
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002722- the pickle module no longer uses the deprecated bin parameter.
2723
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002724- the shelve module no longer uses the deprecated binary parameter.
2725
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002726- the pstats module no longer uses the deprecated ignore() method.
2727
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002728- the filecmp module no longer uses the deprecated use_statcache argument.
2729
Raymond Hettinger664347b2004-12-04 21:21:53 +00002730- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2731 extended or overridden by subclasses. Formerly, the subclassed method would
2732 be ignored by the rest of the module. (Bug #1078905).
2733
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002734- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002735 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002736
Walter Dörwald36733692004-12-22 12:50:50 +00002737- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2738 once when a size argument is given. This prevents a buffer overflow in the
2739 tokenizer with very long source lines.
2740
Barry Warsaw538561e2006-01-01 21:48:54 +00002741- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2742 immediately after creating the object, without any intervening
2743 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002744
Skip Montanaro05885812005-01-16 20:48:27 +00002745- The reconvert.quote function can now emit triple-quoted strings. The
2746 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002747
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002748- ``UserString.MutableString`` now supports negative indices in
2749 ``__setitem__`` and ``__delitem__``
2750
Greg Ward40407942005-03-05 02:53:17 +00002751- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2752 correctly.
2753
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002754- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2755 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2756 character even if the user has passed a size parameter to get a proper
2757 line ending. Remove the special handling of a "\r\n" that has been split
2758 between two lines.
2759
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002760- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2761 about illegal code points. The codec now supports PEP 293 style error
2762 handlers.
2763
Walter Dörwald78a78b02005-09-01 12:04:29 +00002764- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002765 from the input stream, so that the output is a byte string in the correct
2766 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002767
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002768- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2769 considering it exactly like a '*'.
2770
Walter Dörwald007f8df2005-10-09 19:42:27 +00002771- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2772 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002773
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002774- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2775
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002776- Patch #1413711: Certain patterns of differences were making difflib
2777 touch the recursion limit.
2778
Walter Dörwald58917a62006-03-31 15:26:22 +00002779- Bug #947906: An object oriented interface has been added to the calendar
2780 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002781 called as a script (e.g. via ``python -mcalendar``). Localized month and
2782 weekday names can be ouput (even if an exotic encoding is used) using
2783 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002784

2792
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002793- Build support for Win64-AMD64 was added.
2794
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002795- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2796
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002797- Patch #881820: look for openpty and forkpty also in libbsd.
2798
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002799- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2800 The zlib module is now builtin on Windows.
2801
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002802- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2803
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002804- Bug #1189330: configure did not correctly determine the necessary
2805 value of LINKCC if python was built with GCC 4.0.
2806
Trent Mick8321b422005-07-26 02:29:21 +00002807- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2808 vulnerability in zlib 1.2.1 and 1.2.2.
2809
Brett Cannon08cd5982005-04-24 22:26:38 +00002810- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2811 flags that change binary compatibility. Changes were also made to
2812 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002813 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002814
Bob Ippolitoed233462005-03-29 13:47:59 +00002815- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2816 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2817 no longer exists). This configure patch makes things right.
2818
Martin v. Löwise2713be2005-03-08 15:03:08 +00002819- Bug #1158607: Build with --disable-unicode again.
2820
Brett Cannon46d96232005-02-16 00:07:19 +00002821- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2822 defined. Discovered as a result of not being able to build on OS X.
2823
Brett Cannon516592f2004-12-07 00:42:59 +00002824- setup.py now uses the directories specified in LDFLAGS using the -L option
2825 and in CPPFLAGS using the -I option for adding library and include
2826 directories, respectively, for compiling extension modules against. This has
2827 led to the core being compiled using the values in CPPFLAGS. It also removes
2828 the need for the special-casing of both DarwinPorts and Fink for darwin since
2829 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2830 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2831 Fink, ``-I/opt/local/include`` for DarwinPorts).
2832
Brett Cannon43802422005-02-10 20:48:03 +00002833- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2834 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2835 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

Tim Petersc9d78aa2006-03-26 23:27:58 +00002841- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2842 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2843 is obtained via the ``PyObject_`` family, it must be released via the
2844 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2845 always been officially true, but when Python's small-object allocator was
2846 introduced, an attempt was made to cater to a few extension modules
2847 discovered at the time that obtained memory via ``PyObject_New`` but
2848 released it via ``PyMem_DEL``. It's years later, and if such code still
2849 exists it will fail now (probably with segfaults, but calling wrong
2850 low-level memory management functions can yield many symptoms).
2851
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002852- Added a C API for set and frozenset objects.
2853

2855
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002856- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2857 mapping argument now. This string is used as a mapping table. Byte values
2858 greater than the length of the string and 0xFFFE are treated as undefined
2859 mappings.
