641-----------------
642
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000643- Make _PyGILState_NoteThreadState() static, it was not used anywhere
644 outside of pystate.c and should not be necessary.
645
Brett Cannon19d76c52006-09-09 07:18:44 +0000646- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
647 allows calling unicode() on exceptions classes directly to succeed.
648
Georg Brandlecab6232006-09-06 06:47:02 +0000649- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000664- The return tuple from str.rpartition(sep) is (tail, sep, head) where
665 head is the original string if sep was not found.
666
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000667- Bug #1520864: unpacking singleton tuples in list comprehensions and
668 generator expressions (x for x, in ... ) works again. Fixing this problem
669 required changing the .pyc magic number. This means that .pyc files
670 generated before 2.5c2 will be regenerated.

783-----------------
784
Neal Norwitz24b6f202006-09-05 04:43:56 +0000785- Fix infinite recursion when subclassing long and overriding __hash__.
786
787- Fix concatenation (+=) of long strings.
788
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000789- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000790 compared equal or unequal to a string and a UnicodeDecodeError
791 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000792
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000793 Instead, the equal (==) and unequal (!=) comparison operators will
794 now issue a UnicodeWarning and interpret the two objects as
795 unequal. The UnicodeWarning can be filtered as desired using
796 the warning framework, e.g. silenced completely, turned into an
797 exception, logged, etc.
798
799 Note that compare operators other than equal and unequal will still
800 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000801
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000802- Fix segfault when doing string formatting on subclasses of long.
803
804- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
805 with new-style classes.
806
807- Fix bug related to __len__ functions returning negative values with
808 classic classes.
809
810- Patch #1538606, Fix __index__() clipping. There were some problems
811 discovered with the API and how integers that didn't fit into Py_ssize_t
812 were handled. This patch attempts to provide enough alternatives
813 to effectively use __index__.
814
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000815- Bug #1536021: __hash__ may now return long int; the final hash
816 value is obtained by invoking hash on the long int.
817
Thomas Hellerab1049c2006-08-08 17:37:00 +0000818- Bug #1536786: buffer comparison could emit a RuntimeWarning.

821 sys.stdin is closed.
822
Thomas Heller74d36f02006-08-04 18:17:40 +0000823- On Windows, the PyErr_Warn function is now exported from
824 the Python dll again.
825
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000826- Bug #1191458: tracing over for loops now produces a line event
827 on each iteration. Fixing this problem required changing the .pyc
828 magic number. This means that .pyc files generated before 2.5c1
829 will be regenerated.
830
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000831- Bug #1333982: string/number constants were inappropriately stored
832 in the byte code and co_consts even if they were not used, ie
833 immediately popped off the stack.
834
Georg Brandle9462c72006-08-04 18:03:37 +0000835- Fixed a reference-counting problem in property().

840
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000841- Fix a bug in the ``compiler`` package that caused invalid code to be
842 generated for generator expressions.
843
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000844- The distutils version has been changed to 2.5.0. The change to
845 keep it programmatically in sync with the Python version running
846 the code (introduced in 2.5b3) has been reverted. It will continue
847 to be maintained manually as static string literal.
848
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000849- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000850 and this cannot be converted to the required C type, an exception is
851 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000852 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000853
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000854- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000855 an exception.
856
Tim Peterscbdd3502006-09-05 01:47:53 +0000857- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000858 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000859 workarounds for clocks with low resolution, to stop the code yielding
860 duplicate UUIDs.
861
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000862- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
863 before raising SystemExit, allowing IDLE to honor quit() and exit().
864
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000865- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

894
Thomas Heller86720042006-08-14 11:17:48 +0000895- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
896 uses the _as_parameter_ attribute when objects are passed to foreign
897 function calls. The ctypes version number was changed to 1.0.1.
898
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000899- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +0000946What's New in Python 2.5 beta 3?
947================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000948

Neal Norwitza1f10902006-07-12 07:28:29 +0000950
951Core and builtins
952-----------------
953
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000954- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000955 returned a long (see PEP 353).
956
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000957- Bug #1515471: string.replace() accepts character buffers again.
958
Neal Norwitz07aadb12006-07-30 06:55:48 +0000959- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
960 This provides the proper warning for struct.pack().
961 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
962
Neal Norwitz0d62a062006-07-30 06:53:31 +0000963- Patch #1531113: Fix augmented assignment with yield expressions.
964 Also fix a SystemError when trying to assign to yield expressions.
965
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000966- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
967 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
968 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
969 excessive filesystem operations during imports.
970
Tim Petersbc24eee2006-07-27 01:14:53 +0000971- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
972 operations on signed longs that are formally undefined by C.
973 Unfortunately, at least one compiler now cares about that, so complicated
974 the code to make that compiler happy again.
975
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000976- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
977
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000978- Patch #1232023: Stop including current directory in search
979 path on Windows.
980
Neal Norwitze1fdb322006-07-21 05:32:28 +0000981- Fix some potential crashes found with failmalloc.
982
Neal Norwitze7563102006-07-17 01:00:16 +0000983- Fix warnings reported by Klocwork's static analysis tool.
984
Neal Norwitz84be93b2006-07-16 01:50:38 +0000985- Bug #1512814, Fix incorrect lineno's when code within a function
986 had more than 255 blank lines.
987
Georg Brandl9dceedb2006-07-12 15:31:17 +0000988- Patch #1521179: Python now accepts the standard options ``--help`` and
989 ``--version`` as well as ``/?`` on Windows.
990
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000991- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000992 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000993 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000994
Tim Peters112aad32006-07-19 00:03:19 +0000995- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000996 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000997 new ``sys._current_frames()`` returns a dictionary with one entry,
998 mapping the faux "thread id" 0 to the current frame.
999
Ronald Oussoren3075e162006-07-25 20:28:55 +00001000- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001001

Neal Norwitza1f10902006-07-12 07:28:29 +00001003Library
1004-------
1005
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001006- Correction of patch #1455898: In the mbcs decoder, set final=False
1007 for stream decoder, but final=True for the decode function.
1008
Georg Brandl07fec3a2006-08-01 18:49:24 +00001009- os.urandom no longer masks unrelated exceptions like SystemExit or
1010 KeyboardInterrupt.
1011
Tim Peters4643c2f2006-08-10 22:45:34 +00001012- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001013 shutil.copytree on Windows
1014
Georg Brandle34ac7c2006-07-30 11:07:23 +00001015- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1016 refers to file descriptors, not file objects.
1017
Tim Peterscbdd3502006-09-05 01:47:53 +00001018- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001019 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001020 #1513611, and probably others.
1021
Georg Brandledd9b0d2006-07-29 09:33:26 +00001022- Bug #1441397: The compiler module now recognizes module and function
1023 docstrings correctly as it did in Python 2.4.
1024
Tim Peters6f681472006-07-27 23:44:37 +00001025- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1026 lost that tests are sorted by name before being run. This rarely
1027 matters for well-written tests, but can create baffling symptoms if
1028 side effects from one test to the next affect outcomes. ``DocTestFinder``
1029 has been changed to sort the list of tests it returns.
1030
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001031- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001032 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001033
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001034- Bug #978833: Really close underlying socket in _socketobject.close.
1035
Georg Brandldb232dc2006-08-20 13:15:43 +00001036- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1037 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001038
Georg Brandlcf0c1722006-07-26 07:23:32 +00001039- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1040 to recursive calls and call it with the failing package name.
1041
Martin v. Löwis0b483032006-07-25 09:53:12 +00001042- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1043
Georg Brandlc13c34c2006-07-24 14:09:56 +00001044- Patch #1515343: Fix printing of deprecated string exceptions with a
1045 value in the traceback module.
1046
Greg Ward48fae7a2006-07-23 16:05:51 +00001047- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1048
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001049- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1050
Brett Cannoncaebe222006-07-18 04:41:36 +00001051- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1052 argument tuple. For arguments where zero is illegal, the value is forced to
1053 the minimum value that is correct. This is to support an undocumented but
1054 common way people used to fill in inconsequential information in the time
1055 tuple pre-2.4.
1056
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001057- Patch #1220874: Update the binhex module for Mach-O.
1058
Barry Warsawb110bad2006-07-21 14:51:07 +00001059- The email package has improved RFC 2231 support, specifically for
1060 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1061 (name*0=<blah>) parameter continuations. This may change the types of
1062 values returned from email.message.Message.get_param() and friends.
1063 Specifically in some cases where non-encoded continuations were used,
1064 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1065 will just return the string (since non-encoded continuations don't have
1066 charset and language parts).
1067
1068 Also, whereas % values were decoded in all parameter continuations, they are
1069 now only decoded in encoded parameter parts.
1070
Ronald Oussoren3075e162006-07-25 20:28:55 +00001071- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1072
1073- Bug #1517996: IDLE now longer shows the default Tk menu when a
1074 path browser, class browser or debugger is the frontmost window on MacOS X
1075
Barry Warsaw00decd72006-07-27 23:43:15 +00001076- Patch #1520294: Support for getset and member descriptors in types.py,
1077 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1078 of an object against these built-in types and more importantly, for getting
1079 their docstrings printed in the interactive interpreter's help() function.

1083-----------------
1084
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001085- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1086 a socket operation on a socket with a timeout, the exception will be
1087 caught correctly. Previously, the exception was not caught.
1088
Thomas Heller1393d6a2006-07-28 21:43:20 +00001089- Patch #1529514: The _ctypes extension is now compiled on more
1090 openbsd target platforms.
1091
Tim Peters9cab5932006-07-28 00:30:00 +00001092- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1093 a memory leak, affecting pickles and deep copies.
1094
Tim Petersbc24eee2006-07-27 01:14:53 +00001095- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001096 Paul Eggert.
1097
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001098- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1099
Thomas Hellerce049a02006-07-14 17:51:14 +00001100- Patch #1521817: Index range checking on ctypes arrays containing
1101 exactly one element enabled again. This allows iterating over these
1102 arrays, without the need to check the array size before.
1103
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001104- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001105 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001106 /dev/null in certain cases; this is now fixed.
1107
Thomas Heller47d7a062006-07-12 08:43:47 +00001108- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1109 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001110
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001111- Because of a misspelled preprocessor symbol, ctypes was always
1112 compiled without thread support; this is now fixed.
1113
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001114- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1115 methods now allow their database parameter to be None as the
1116 sleepycat API allows.
1117
Matt Flemingec926502006-07-28 11:27:27 +00001118- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1119 bluetooth API compared with Linux and FreeBSD.
1120
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001121Tests
1122-----
1123
1124- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1125 how long the test file should take to play. Now accepts taking 2.93 secs
1126 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1127
Georg Brandl4793aa32006-07-28 18:31:39 +00001128- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1129 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1130 run via ``regrtest.py``. Now they do.

1139
1140- PythonLauncher now works correctly when the path to the script contains
1141 characters that are treated specially by the shell (such as quotes).
1142
1143- Bug #1527397: PythonLauncher now launches scripts with the working directory
1144 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001145 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001146 expect.

1159
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001160- Bug #1501934: The scope of global variables that are locally assigned

1167 and atof().
1168
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001169- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to

1180
Tim Peters32a83612006-07-10 21:08:24 +00001181- New function ``sys._current_frames()`` returns a dict mapping thread
1182 id to topmost thread stack frame. This is for expert use, and is
1183 especially useful for debugging application deadlocks. The functionality
1184 was previously available in Fazal Majid's ``threadframe`` extension
1185 module, but it wasn't possible to do this in a wholly threadsafe way from
1186 an extension.

1203
Thomas Woutersadd19112006-07-05 11:03:49 +00001204- string.Template() now correctly handles tuple-values. Previously,
1205 multi-value tuples would raise an exception and single-value tuples would
1206 be treated as the value they contain, instead.
1207
Martin v. Löwisede77f52006-07-03 13:01:35 +00001208- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1233
Brett Cannon53ab5b72006-06-22 16:49:14 +00001234- Bug #1510580: The 'warnings' module improperly required that a Warning
1235 category be either a types.ClassType and a subclass of Warning. The proper
1236 check is just that it is a subclass with Warning as the documentation states.
1237
Georg Brandlad29e632006-06-21 17:45:17 +00001238- The compiler module now correctly compiles the new try-except-finally
1239 statement (bug #1509132).
1240
Neal Norwitz60373cd2006-06-22 06:30:50 +00001241- The wsgiref package is now installed properly on Unix.

1245
Gerhard Häring762fbd32006-07-02 17:48:30 +00001246- The sqlite3 module did cut off data from the SQLite database at the first
1247 null character before sending it to a custom converter. This has been fixed
1248 now.

1251-----------------
1252
Tim Peters112aad32006-07-19 00:03:19 +00001253- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1254 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1255 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001256
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001257- Assigning None to pointer type fields in ctypes structures possible
1258 overwrote the wrong fields, this is fixed now.
1259
1260- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1261 on non-Windows platforms.
1262
1263- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1264 integer or long, without range checking.
1265
1266- Patch #1517790: It is now possible to use custom objects in the ctypes
1267 foreign function argtypes sequence as long as they provide a from_param
1268 method, no longer is it required that the object is a ctypes type.
1269
1270- The '_ctypes' extension module now works when Python is configured
1271 with the --without-threads option.
1272
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001273- Bug #1513646: os.access on Windows now correctly determines write

1288
Tim Peters32a83612006-07-10 21:08:24 +00001289- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001290 Previously, the slight difference could cause compilation errors of the
1291 'zlib' module on systems with more than one version of zlib.
1292
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001293- The MSI compileall step was fixed to also support a TARGETDIR

1325-----------------
1326
Georg Brandla56b9152006-06-19 06:35:54 +00001327- Patch #1507676: Error messages returned by invalid abstract object operations
1328 (such as iterating over an integer) have been improved and now include the
1329 type of the offending object to help with debugging.
1330
Brett Cannonea3912b2006-06-13 21:46:41 +00001331- Bug #992017: A classic class that defined a __coerce__() method that returned
1332 its arguments swapped would infinitely recurse and segfault the interpreter.
1333
Neal Norwitz909eb122006-06-12 02:13:21 +00001334- Fix the socket tests so they can be run concurrently.
1335
Neal Norwitzb9845e72006-06-12 02:11:18 +00001336- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001337 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001338
Brett Cannon22565aa2006-06-09 22:31:23 +00001339- Bug #532646: object.__call__() will continue looking for the __call__
1340 attribute on objects until one without one is found. This leads to recursion
1341 when you take a class and set its __call__ attribute to an instance of the
1342 class. Originally fixed for classic classes, but this fix is for new-style.
1343 Removes the infinite_rec_3 crasher.
1344
Georg Brandl24250812006-06-09 18:45:48 +00001345- The string and unicode methods startswith() and endswith() now accept
1346 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1347
Brett Cannonde3b0522006-06-08 17:00:45 +00001348- Buffer objects, at the C level, never used the char buffer
1349 implementation even when the char buffer for the wrapped object was
1350 explicitly requested (originally returned the read or write buffer).
1351 Now a TypeError is raised if the char buffer is not present but is
1352 requested.
1353
Georg Brandlddbaa662006-06-04 21:56:52 +00001354- Patch #1346214: Statements like "if 0: suite" are now again optimized
1355 away like they were in Python 2.4.
1356
Georg Brandlb7c8f542006-05-27 12:30:25 +00001357- Builtin exceptions are now full-blown new-style classes instead of
1358 instances pretending to be classes, which speeds up exception handling
1359 by about 80% in comparison to 2.5a2.
1360
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001361- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1362 Unicode 4.1.
1363
Georg Brandlf4ef1162006-05-26 18:03:31 +00001364- Patch #921466: sys.path_importer_cache is now used to cache valid and
1365 invalid file paths for the built-in import machinery which leads to
1366 fewer open calls on startup.
1367
Tim Peters696cf432006-05-24 21:10:40 +00001368- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1369 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1370 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1371 the number of input digits (it was and remains linear-time for bases
1372 2, 4, 8, 16 and 32).
1373
Tim Petersb713ec22006-05-23 18:45:30 +00001374- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1375 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1376 an integer close to ``sys.maxint``. This was repaired by patch
1377 #1335972, which also gives a nice speedup.
1378
Richard Jonescebbefc2006-05-23 18:28:17 +00001379- Patch #1337051: reduced size of frame objects.
1380
1381- PyErr_NewException now accepts a tuple of base classes as its
1382 "base" parameter.
1383
Richard Jones7c88dcc2006-05-23 10:37:38 +00001384- Patch #876206: function call speedup by retaining allocated frame
1385 objects.
1386
Georg Brandl7b90e162006-05-18 07:01:27 +00001387- Bug #1462152: file() now checks more thoroughly for invalid mode
1388 strings and removes a possible "U" before passing the mode to the
1389 C library function.
1390
Neal Norwitz1004a532006-05-15 07:17:23 +00001391- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1392
Neal Norwitz373f0a72006-05-15 07:04:36 +00001393- Bug #1487966: Fix SystemError with conditional expression in assignment
1394
Martin v. Löwis879768d2006-05-11 13:28:43 +00001395- WindowsError now has two error code attributes: errno, which carries
1396 the error values from errno.h, and winerror, which carries the error
1397 values from winerror.h. Previous versions put the winerror.h values
1398 (from GetLastError()) into the errno attribute.
1399
Martin v. Löwis77736712006-05-04 05:51:03 +00001400- Patch #1475845: Raise IndentationError for unexpected indent.
1401
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001402- Patch #1479181: split open() and file() from being aliases for each other.
1403
Tim Peters44bd9862006-06-01 13:49:23 +00001404- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1405 methods were always silently ignored by dictionaries when comparing keys.
1406 They are now passed through (except when using the C API function
1407 ``PyDict_GetItem()``, whose semantics did not change).
1408
1409- Bug #1456209: In some obscure cases it was possible for a class with a
1410 custom ``__eq__()`` method to confuse dict internals when class instances
1411 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1412 No, you don't have any code that did this ;-)

1420
Brett Cannon6ee7d012006-06-08 16:23:04 +00001421- Change binascii.hexlify to accept a read-only buffer instead of only a char
1422 buffer and actually follow its documentation.
1423
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001424- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1425
Nick Coghlanc649ec52006-05-29 12:43:05 +00001426- Patch #1478788 (modified version): The functional extension module has
1427 been renamed to _functools and a functools Python wrapper module added.
1428 This provides a home for additional function related utilities that are
1429 not specifically about functional programming. See PEP 309.
1430
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001431- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001435- Patch #1435422: zlib's compress and decompress objects now have a
1436 copy() method.
1437
Andrew MacIntyre92913322006-06-13 15:04:24 +00001438- Patch #1454481: thread stack size is now tunable at runtime for thread
1439 enabled builds on Windows and systems with Posix threads support.
1440
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001441- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1442 (up to the system limit of 32K characters).
1443
1444- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1445 As a result, these functions now raise WindowsError instead of OSError.
1446
Tim Peters7a822da2006-05-25 21:50:17 +00001447- ``time.clock()`` on Win64 should use the high-performance Windows
1448 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1449 Windows platforms).
1450
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001451- Calling Tk_Init twice is refused if the first call failed as that
1452 may deadlock.
1453
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001454- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1455 accept it without potentially using an uninitialized pointer.
1456
1457- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1458 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1468 results. It could previously incorrectly return 0 in some cases.
1469 Fixes SF bug 1493322 (pybsddb bug 1184012).
1470
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001471- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1472 aborts the db transaction safely when a modifier callback fails.

Gregory P. Smith506f7b52006-06-15 08:52:32 +00001475- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001476 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001477 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1478 database calls that would previously deadlock. [SF python bug #775414]
1479
Vinay Sajip28e57612006-07-01 10:45:20 +00001480- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1489 functions.
1490
Martin v. Löwis3798da02006-06-17 18:44:27 +00001491- Patch #812986: Update turtle output even if not tracing.

1502 mime.types file for determining MIME types.
1503
Georg Brandl2605ca82006-06-14 06:08:31 +00001504- Bug #1339007: Shelf objects now don't raise an exception in their
1505 __del__ method when initialization failed.
1506
Martin v. Löwisd8251432006-06-14 05:21:04 +00001507- Patch #1455898: The MBCS codec now supports the incremental mode for
1508 double-byte encodings.
1509
Tim Peters43898b42006-06-14 04:09:25 +00001510- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1511 guarantee that adjacent triples in the return list always describe
1512 non-adjacent blocks. Previously, a pair of matching blocks could end
1513 up being described by multiple adjacent triples that formed a partition
1514 of the matching pair.
1515
Greg Ward0e0c9f42006-06-11 16:24:11 +00001516- Bug #1498146: fix optparse to handle Unicode strings in option help,
1517 description, and epilog.
1518
Greg Wardd1c797e2006-06-11 14:42:41 +00001519- Bug #1366250: minor optparse documentation error.
1520
Greg Ward7f547402006-06-11 00:40:49 +00001521- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1522 clarify docs.
1523
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001524- The wsgiref package has been added to the standard library.
1525
Nick Coghlan676725d2006-06-08 13:54:49 +00001526- The functions update_wrapper() and wraps() have been added to the functools
1527 module. These make it easier to copy relevant metadata from the original
1528 function when writing wrapper functions.
1529
Tim Petersd6a9eef2006-06-05 01:48:21 +00001530- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1531 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001532
Martin v. Löwis3f767792006-06-04 19:36:28 +00001533- Patch #1359618: Speed up charmap encoder by using a trie structure
1534 for lookup.
1535
Tim Petersd609b1a2006-06-02 23:22:51 +00001536- The functions in the ``pprint`` module now sort dictionaries by key
1537 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1538 if and only if its display required more than one line, although that
1539 wasn't documented. The new behavior increases predictability; e.g.,
1540 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1541
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001542- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1543 (thanks for J. J. Lee).
1544
Georg Brandl2b330372006-05-28 20:23:12 +00001545- Patch #1496206: improve urllib2 handling of passwords with respect to
1546 default HTTP and HTTPS ports.
1547
George Yoshidaf3c65de2006-05-28 16:39:09 +00001548- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1549
Bob Ippolito7298f272006-05-23 18:43:47 +00001550- Patch #1281707: speed up gzip.readline.
1551
Georg Brandlb89316f2006-05-17 15:51:16 +00001552- Patch #1180296: Two new functions were added to the locale module:
1553 format_string() to get the effect of "format % items" but locale-aware,
1554 and currency() to format a monetary number with currency sign.
1555
Georg Brandle3a25832006-05-17 14:56:04 +00001556- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1557 and several features added, such as speed and geometry control.
1558
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001559- Patch #1488881: add support for external file objects in bz2 compressed
1560 tarfiles.
1561
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001562- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1563 stdout arguments, making it possible to redirect input and output
1564 for remote debugging.
1565
1566- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1567 a couple of issues, notably handling of long file names using the
1568 GNU LONGNAME extension.
1569
1570- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1571 new flag when ``name`` is already the name of an option flag.
1572
1573- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1574 package.
1575
1576- Patch #1472854: make the rlcompleter.Completer class usable on non-
1577 UNIX platforms.
1578
1579- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1580
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001581- Bug #1472827: correctly escape newlines and tabs in attribute values in
1582 the saxutils.XMLGenerator class.

1618-----------------
1619
Thomas Heller1b046642006-04-18 18:51:06 +00001620- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1621 by converting these apis from macros into exported functions again:
1622
1623 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1624 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1625 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1626 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1627 PyRun_String Py_CompileString
1628
Martin v. Löwis45294a92006-04-18 06:24:08 +00001629- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1630
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001631- All uses of PyStructSequence_InitType have been changed to initialize
1632 the type objects only once, even if the interpreter is initialized
1633 multiple times.
1634
Neal Norwitz61546162006-04-14 05:20:28 +00001635- Bug #1454485, array.array('u') could crash the interpreter. This was
1636 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1637 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1638
1639- Py_UNICODE is unsigned. It was always documented as unsigned, but
1640 due to a bug had a signed value in previous versions.
1641
Tim Peters3a5e8b12006-04-11 01:44:07 +00001642- Patch #837242: ``id()`` of any Python object always gives a positive
1643 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1644 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001645 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001646 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001647
Tim Peters3a5e8b12006-04-11 01:44:07 +00001648 def __hash__(self):
1649 return id(self) # WRONG
1650
1651 because a hash result must be a (short) Python int but it was always
1652 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001653 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001654 was always usable as a hash value before this patch. That's no longer
1655 necessarily so.
1656
1657- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001658 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001659 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001660 #1454844)
1661
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001662- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1663 involving generators that have paused outside of any ``try`` or ``with``
1664 blocks. (In 2.5a1, a paused generator that was part of a reference
1665 cycle could not be garbage collected, regardless of whether it was
1666 paused in a ``try`` or ``with`` block.)

1700 or exception is ignored).
1701
Nick Coghlanda2268f2006-04-24 04:37:15 +00001702- Fixed contextlib.nested to cope with exceptions being raised and
1703 caught inside exit handlers.
1704
Greg Wardab05edc2006-04-23 03:47:58 +00001705- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1706 hex, octal, or binary; add ``append_const`` action; keep going if
1707 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1708 added ``epilog`` for better help generation).
1709
Tim Peters21fbd572006-04-21 21:18:10 +00001710- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1711 called from a thread spawned as a side effect of importing a module.
1712
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001713- The pydoc module now supports documenting packages contained in
1714 .zip or .egg files.
1715
1716- The pkgutil module now has several new utility functions, such
1717 as ``walk_packages()`` to support working with packages that are either
1718 in the filesystem or zip files.
1719
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001720- The mailbox module can now modify and delete messages from

1722 K. Johnson for writing the code, and to the 2005 Google Summer of
1723 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001724
Tim Petersc7605f22006-04-17 21:12:33 +00001725- The ``__del__`` method of class ``local`` in module ``_threading_local``
1726 returned before accomplishing any of its intended cleanup.
1727
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001728- Patch #790710: Add breakpoint command lists in pdb.

Nick Coghlan27ec1a72006-04-24 04:32:47 +00001780- test_cmd_line now checks operation of the -m and -c command switches
1781
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001782- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1783 it separately and by hand. It also wasn't cleaning up its changes to
1784 the current Decimal context.
1785
Thomas Woutersabd08882006-04-26 15:53:30 +00001786- regrtest.py now has a -M option to run tests that test the new limits of
1787 containers, on 64-bit architectures. Running these tests is only sensible
1788 on 64-bit machines with more than two gigabytes of memory. The argument
1789 passed is the maximum amount of memory for the tests to use.

1798-------------
1799
Tim Petersb06d28c2006-05-12 01:57:59 +00001800- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1801
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001802- PEP 343: Added Context Types section to the library reference
1803 and attempted to bring other PEP 343 related documentation into
1804 line with the implementation and/or python-dev discussions.
1805
Tim Peters8dc73d22006-04-24 02:03:16 +00001806- Bug #1337990: clarified that ``doctest`` does not support examples
1807 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001810What's New in Python 2.5 alpha 1?
1811=================================
1812
Anthony Baxterebed3f62006-04-03 15:03:44 +00001813*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001814
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001815Core and builtins
1816-----------------
1817
Nick Coghlan43832302006-04-23 17:04:07 +00001818- PEP 338: -m command line switch now delegates to runpy.run_module
1819 allowing it to support modules in packages and zipfiles
1820
Martin v. Löwisc661b882006-04-20 04:54:23 +00001821- On Windows, .DLL is not an accepted file name extension for
1822 extension modules anymore; extensions are only found if they
1823 end in .PYD.
1824
Martin v. Löwisea62d252006-04-03 10:56:49 +00001825- Bug #1421664: sys.stderr.encoding is now set to the same value as
1826 sys.stdout.encoding.
1827
Neal Norwitz92e212f2006-04-03 04:48:37 +00001828- __import__ accepts keyword arguments.
1829
Georg Brandlccadf842006-03-31 18:54:53 +00001830- Patch #1460496: round() now accepts keyword arguments.
1831
Anthony Baxter262c00a2006-03-30 10:53:17 +00001832- Fixed bug #1459029 - unicode reprs were double-escaped.
1833
Hye-Shik Changd478f342006-03-23 12:32:36 +00001834- Patch #1396919: The system scope threads are reenabled on FreeBSD
1835 5.4 and later versions.
1836
Neal Norwitze98ccf62006-03-23 05:39:47 +00001837- Bug #1115379: Compiling a Unicode string with an encoding declaration
1838 now gives a SyntaxError.
1839
Georg Brandlabd1ff82006-03-18 07:59:59 +00001840- Previously, Python code had no easy way to access the contents of a
1841 cell object. Now, a ``cell_contents`` attribute has been added
1842 (closes patch #1170323).
1843
Tim Peterscf79aac2006-03-16 01:14:46 +00001844- Patch #1123430: Python's small-object allocator now returns an arena to
1845 the system ``free()`` when all memory within an arena becomes unused
1846 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1847 freed. Some applications will see a drop in virtual memory size now,
1848 especially long-running applications that, from time to time, temporarily
1849 use a large number of small objects. Note that when Python returns an
1850 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001851 platform C library will in turn return that memory to the operating system.
1852 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001853 appears to be effective at least on Microsoft C and gcc-based systems.
1854 Thanks to Evan Jones for hard work and patience.
1855
Georg Brandl533ff6f2006-03-08 18:09:27 +00001856- Patch #1434038: property() now uses the getter's docstring if there is
1857 no "doc" argument given. This makes it possible to legitimately use
1858 property() as a decorator to produce a read-only property.
1859
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001860- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1861 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1862 of requiring an int or long in slicing and a few other contexts, enabling
1863 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1864
Neal Norwitz995acdf2006-03-07 05:01:00 +00001865- Fixed various bugs reported by Coverity's Prevent tool.
1866
Brett Cannonbf364092006-03-01 04:25:17 +00001867- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1868 new exception base class, BaseException, which has a new message attribute.
1869 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1870 Raising a string exception now raises a DeprecationWarning.
1871
Thomas Woutersfb609f42006-02-28 16:37:25 +00001872- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1873 explicitly relative, using 'from .module import name' to mean 'from the same
1874 package as this module is in. Imports without dots still default to the
1875 old relative-then-absolute, unless 'from __future__ import
1876 absolute_import' is used.
1877
Brett Cannona7446e32006-02-27 23:39:10 +00001878- Properly check if 'warnings' raises an exception (usually when a filter set
1879 to "error" is triggered) when raising a warning for raising string
1880 exceptions.
1881
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001882- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001883 The name was removed from Include/code.h.
1884
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001885- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001886
Guido van Rossum1968ad32006-02-25 22:38:04 +00001887- Patch 1433928:
1888 - The copy module now "copies" function objects (as atomic objects).
1889 - dict.__getitem__ now looks for a __missing__ hook before raising
1890 KeyError.
1891
Tim Peters84ef21c2006-02-28 20:39:06 +00001892- PEP 343: with statement implemented. Needs ``from __future__ import
1893 with_statement``. Use of 'with' as a variable will generate a warning.
1894 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001895 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001896 The following objects have __context__ methods:
1897 - The built-in file type.
1898 - The thread.LockType type.
1899 - The following types defined by the threading module:
1900 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1901 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001902
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001903- Fix the encodings package codec search function to only search
1904 inside its own package. Fixes problem reported in patch #1433198.
1905
1906 Note: Codec packages should implement and register their own
1907 codec search function. PEP 100 has the details.
1908
Tim Peters9ea89d22006-06-04 03:26:02 +00001909- PEP 353: Using ``Py_ssize_t`` as the index type.
1910
1911- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1912 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1913 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1914 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1915 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001916
Neal Norwitzfc76d632006-01-10 06:03:13 +00001917- Patch #1400181, fix unicode string formatting to not use the locale.
1918 This is how string objects work. u'%f' could use , instead of .
1919 for the decimal point. Now both strings and unicode always use periods.
1920
Neal Norwitz671b9e32006-01-09 07:07:12 +00001921- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1922 configure would break checking curses.h.
1923
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001924- Bug #959576: The pwd module is now builtin. This allows Python to be
1925 built on UNIX platforms without $HOME set.
1926
Neal Norwitzc10978f2005-12-19 06:07:16 +00001927- Bug #1072182, fix some potential problems if characters are signed.
1928
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001929- Bug #889500, fix line number on SyntaxWarning for global declarations.
1930
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001931- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1932
Neal Norwitze7214a12005-12-18 05:03:17 +00001933- Support for converting hex strings to floats no longer works.
1934 This was not portable. float('0x3') now raises a ValueError.
1935
Barry Warsaw2a38a862005-12-18 01:27:35 +00001936- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001937 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001938 is now displayed in interactive prompt banner.
1939
Georg Brandlfa166682005-12-17 21:45:17 +00001940- Implementation of PEP 341 - Unification of try/except and try/finally.
1941 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001942 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001943
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001944- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1945 now encodes backslash correctly.
1946
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001947- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1948
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001949- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001950 and long longs.
1951
Neal Norwitz67715f02005-11-09 06:59:35 +00001952- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001953 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001954 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001955
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001956- Replaced most Unicode charmap codecs with new ones using the
1957 new Unicode translate string feature in the builtin charmap
1958 codec; the codecs were created from the mapping tables available
1959 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1960 encodings now include a mapping for the Apple logo)
1961
Tim Peterse3547fd2005-12-16 23:13:57 +00001962- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001963
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001964- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001965
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001966- A new AST parser implementation was completed. The abstract
1967 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001968 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001969
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001970- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001971 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1972
Neal Norwitz708e51a2005-10-03 04:48:15 +00001973- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1974
Neal Norwitz11bd1192005-10-03 00:54:56 +00001975- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1976 Provide a warning when a directory is passed on the command line.
1977
Neal Norwitz40d37812005-10-02 01:48:49 +00001978- Fix segfault with invalid coding.
1979
1980- SF bug #772896: unknown encoding results in MemoryError.
1981
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001982- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001983 supported a __len__() method which evaluated to False when the iterator
1984 was empty.
1985
Guido van Rossum630db602005-09-20 18:49:54 +00001986- On 64-bit platforms, when __len__() returns a value that cannot be
1987 represented as a C int, raise OverflowError.
1988
Skip Montanarof8948ca2005-09-19 03:54:46 +00001989- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001990 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001991
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001992- SF bug #893549: parsing keyword arguments was broken with a few format
1993 codes.
1994
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001995- Changes donated by Elemental Security to make it work on AIX 5.3
1996 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1997 bug #105470: test_pwd fails on 64bit system (Opteron).
1998
Guido van Rossum539c6622005-09-14 17:49:54 +00001999- Changes donated by Elemental Security to make it work on HP-UX 11 on
2000 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2001
Georg Brandl4550b8d2005-08-26 06:43:52 +00002002- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002003 (fixes bug #1119418).
2004
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002005- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2006
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002007- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2008 exceptions that cause a function to exit.
2009
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002010- The implementation of set() and frozenset() was revised to use its
2011 own internal data structure. Memory consumption is reduced by 1/3
2012 and there are modest speed-ups as well. The API is unchanged.
2013
Tim Petersde7990b2005-07-17 23:45:23 +00002014- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2015
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002016- SF bug #1229429: PyObject_CallMethod failed to decrement some
2017 reference counts in some error exit cases.
2018
Tim Petersecc6e6a2005-07-10 22:30:55 +00002019- SF bug #1185883: Python's small-object memory allocator took over
2020 a block managed by the platform C library whenever a realloc specified
2021 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002022 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002023 portable way to copy data from the C-managed block into Python's
2024 small-object space without risking a memory fault. Python's small-object
2025 realloc now leaves such blocks under the control of the platform C
2026 realloc.
2027
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002028- SF bug #1232517: An overflow error was not detected properly when
2029 attempting to convert a large float to an int in os.utime().
2030
Raymond Hettinger3296e692005-06-29 23:29:56 +00002031- SF bug #1224347: hex longs now print with lowercase letters just
2032 like their int counterparts.
2033
Michael W. Hudson188d4362005-06-20 16:52:57 +00002034- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2035 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2036 interpreter states; back out that fix and do a better job (see
2037 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2038 for a longer write-up of the problem).
2039
Michael W. Hudsondf888462005-06-03 14:41:55 +00002040- SF patch #1180995: marshal now uses a binary format by default when
2041 serializing floats.
2042
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002043- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2044 the routines that promise to produce IEEE 754 binary representations
2045 of floats now simply copy bytes around.
2046
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002047- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2048 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +00002050- patch #1109424: int, long, float, complex, and unicode now check for the
2051 proper magic slot for type conversions when subclassed. Previously the
2052 magic slot was ignored during conversion. Semantics now match the way
2053 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002054 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002055 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002056 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002058- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2059 NULL, now raise an AttributeError when attempting to set or delete the
2060 attribute. Previously a TypeError was raised, but this was inconsistent
2061 with the equivalent pure-Python implementation.
2062
Michael W. Hudson774479c2005-04-18 08:46:17 +00002063- It is now safe to call PyGILState_Release() before
2064 PyEval_InitThreads() (note that if there is reason to believe there
2065 are multiple threads around you still must call PyEval_InitThreads()
2066 before using the Python API; this fix is for extension modules that
2067 have no way of knowing if Python is multi-threaded yet).
2068
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002069- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2070 disabled caused a crash.
2071
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002072- Bug #1165306: instancemethod_new allowed the creation of a method
2073 with im_class == im_self == NULL, which caused a crash when called.
2074
Tim Petersecc6e6a2005-07-10 22:30:55 +00002075- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002076 fixes the crash seen in bug #1165761
2077
Raymond Hettinger96229b12005-03-11 06:49:40 +00002078- Added two new builtins, any() and all().
2079
Brett Cannon409d8f22005-03-05 06:47:57 +00002080- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002081 (e.g., ``class C(): pass`` is no longer a syntax error).
2082 Patch #1176012 added support to the 'parser' module and 'compiler' package
2083 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002084
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002085- Patch #1115086: Support PY_LONGLONG in structmember.
2086
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002087- Bug #1155938: new style classes did not check that __init__() was
2088 returning None.
2089
Tim Petersecc6e6a2005-07-10 22:30:55 +00002090- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002091 ('\') with a specific error message.
2092
Martin v. Löwisff232d72005-03-03 09:24:38 +00002093- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2094
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002095- Bug #1124295: the __name__ attribute of file objects was
2096 inadvertently made inaccessible in restricted mode.
2097
Tim Petersecc6e6a2005-07-10 22:30:55 +00002098- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002099 an ferror() call.
2100
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002101- min() and max() now support key= arguments with the same meaning as in
2102 list.sort().
2103
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002104- The peephole optimizer now performs simple constant folding in expressions:
2105 (2+3) --> (5).
2106
Raymond Hettingera422c342005-01-11 03:03:27 +00002107- set and frozenset objects can now be marshalled. SF #1098985.
2108
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002109- Bug #1077106: Poor argument checking could cause memory corruption
2110 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002111
Jeremy Hyltonab630502005-02-04 18:44:06 +00002112- The parser did not complain about future statements in illegal
2113 positions. It once again reports a syntax error if a future
2114 statement occurs after anything other than a doc string.
2115
Neil Schemenauercf52c072005-08-12 17:34:58 +00002116- Change the %s format specifier for str objects so that it returns a
2117 unicode instance if the argument is not an instance of basestring and
2118 calling __str__ on the argument returns a unicode instance.
2119
Tim Petersf4e69282006-02-27 17:15:31 +00002120- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2121 current thread state when the auto-GIL-state machinery knows about
2122 it (since the thread state is being deleted, continuing to remember it
2123 can't help, but can hurt if another thread happens to get created with
2124 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002316- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2317 been renamed to have only a single underscore prefix. This was done to
2318 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002319
Nick Coghlan43832302006-04-23 17:04:07 +00002320- PEP 338: new module runpy defines a run_module function to support
2321 executing modules which provide access to source code or a code object
2322 via the PEP 302 import mechanisms.
2323
Anthony Baxter93f5b932006-04-03 08:05:07 +00002324- The email module's parsedate_tz function now sets the daylight savings
2325 flag to -1 (unknown) since it can't tell from the date whether it should
2326 be set.
2327

2332 in attribute values.
2333
Anthony Baxterc51ee692006-04-01 00:57:31 +00002334- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002335 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002336 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002337 module will not be built.
2338
Tim Petersc17976e2006-04-01 00:26:53 +00002339- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2340 aren't officially supported here, and trying to use them will probably
2341 raise an exception some day. But dicts have been allowed, and "mostly
2342 worked", so support for them won't go away without warning.
2343
Georg Brandl338ef7d2006-03-31 18:42:16 +00002344- Bug #1445068: getpass.getpass() can now be given an explicit stream
2345 argument to specify where to write the prompt.
2346
Georg Brandl22ec80b2006-03-31 18:25:44 +00002347- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2353 key to be used for signing the uploaded code.
2354
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002355- Queue.Queue objects now support .task_done() and .join() methods
2356 to make it easier to monitor when daemon threads have completed
2357 processing all enqueued tasks. Patch #1455676.
2358
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002359- popen2.Popen objects now preserve the command in a .cmd attribute.
2360
Thomas Hellerc61c0492006-03-22 10:09:27 +00002361- Added the ctypes ffi package.
2362
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002363- email 4.0 package now integrated. This is largely the same as the email 3.0
2364 package that was included in Python 2.3, except that PEP 8 module names are
2365 now used (e.g. mail.message instead of email.Message). The MIME classes
2366 have been moved to a subpackage (e.g. email.mime.text instead of
2367 email.MIMEText). The old names are still supported for now. Several
2368 deprecated Message methods have been removed and lots of bugs have been
2369 fixed. More details can be found in the email package documentation.
2370
Walter Dörwald40108c92006-03-27 08:15:44 +00002371- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2372 (a subclass of tuple) that provides incremental decoders and encoders
2373 (a way to use stateful codecs without the stream API). Python functions
2374 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2375 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2376 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002377
Walter Dörwald067db482006-03-15 22:17:27 +00002378- Patch #1359365: Calling next() on a closed StringIO.String object raises
2379 a ValueError instead of a StopIteration now (like file and cString.String do).
2380 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2381 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002382
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002383- A regrtest option -w was added to re-run failed tests in verbose mode.
2384

2386 interpreter to exit.
2387
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002388- The function get_count() has been added to the gc module, and gc.collect()
2389 grew an optional 'generation' argument.
2390
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002391- A library msilib to generate Windows Installer files, and a distutils

2395 and helpful context managers nested() and closing().
2396

2456 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2457 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2458 Ronald L. Rivest offered this advice for Python:
2459
2460 "The consensus of researchers in this area (at least as
2461 expressed at the NIST Hash Function Workshop 10/31/05),
2462 is that SHA-256 is a good choice for the time being, but
2463 that research should continue, and other alternatives may
2464 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002465
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002466- Added a subset of Fredrik Lundh's ElementTree package. Available

2577 files to PyPI.
2578
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002579- distutils.commands.register now encodes the data as UTF-8 before posting
2580 them to PyPI.
2581
Raymond Hettinger267b8682005-03-27 10:47:39 +00002582- decimal operator and comparison methods now return NotImplemented
2583 instead of raising a TypeError when interacting with other types. This
2584 allows other classes to implement __radd__ style methods and have them
2585 work as expected.
2586
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002587- Bug #1163325: Decimal infinities failed to hash. Attempting to
2588 hash a NaN raised an InvalidOperation instead of a TypeError.
2589
Tim Petersecc6e6a2005-07-10 22:30:55 +00002590- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002591 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2592
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002593- Patch #1043890: Add extractall method to tarfile.
2594
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002595- Patch #1075887: Don't require MSVC in distutils if there is nothing
2596 to build.
2597
Martin v. Löwis637431b2005-03-03 23:12:42 +00002598- Patch #1103407: Properly deal with tarfile iterators when untarring
2599 symbolic links on Windows.
2600
Tim Petersecc6e6a2005-07-10 22:30:55 +00002601- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002602 profile.py if available.
2603
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002604- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2605
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002606- Patch #1117454: Remove code to special-case cookies without values
2607 in LWPCookieJar.
2608
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002609- Patch #1117339: Add cookielib special name tests.
2610
Martin v. Löwise869eb12005-03-03 09:46:07 +00002611- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2612
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002613- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2614
Martin v. Löwisdf241532005-03-03 08:17:42 +00002615- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2616
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002617- Patch #1104111: Alter setup.py --help and --help-commands.
2618
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002619- Patch #1121234: Properly cleanup _exit and tkerror commands.
2620
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002621- Patch #1049151: xdrlib now unpacks booleans as True or False.
2622
Raymond Hettingerbab41432005-02-05 01:31:19 +00002623- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2624
Guido van Rossumd0641422005-02-03 15:01:24 +00002625- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2626 disables recursive traversal through instance attributes, which can
2627 be exploited in various ways.
2628
Tim Peterse3547fd2005-12-16 23:13:57 +00002629- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002630 flags on the HTTP listening socket.
2631
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002632- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2633 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2634
Fred Drakefbdeaad2006-07-29 16:56:15 +00002635- Patches #893642, #1039083: add allow_none, encoding arguments to
2636 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002637
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002638- Bug #1110478: Revert os.environ.update to do putenv again.
2639
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002640- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2641
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002642- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2643
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002644- Enhancements to the csv module:
2645
2646 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002647 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002648 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002649 + Dialect parameter parsing has been re-implemented to improve error
2650 reporting.
2651 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2652 dictates.
2653 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002654 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002655 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002656 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2657 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002658 + reader now allows \r characters to be quoted (previously it only allowed
2659 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002660 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002661 + Dialect classes passed to the module are no longer instantiated by
2662 the module before being parsed (the former validation scheme required
2663 this, but the mechanism was unreliable).
2664 + The dialect registry now contains instances of the internal
2665 C-coded dialect type, rather than references to python objects.
2666 + the internal c-coded dialect type is now immutable.
2667 + register_dialect now accepts the same keyword dialect specifications
2668 as the reader and writer, allowing the user to register dialects
2669 without first creating a dialect class.
2670 + a configurable limit to the size of parsed fields has been added -
2671 previously, an unmatched quote character could result in the entire
2672 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002673 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002674 the parser field size limit (returning the former limit). The initial
2675 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002676 + A line_num attribute has been added to the reader object, which tracks
2677 the number of lines read from the source iterator. This is not
2678 the same as the number of records returned, as records can span
2679 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002680 + reader and writer objects were not being registered with the cyclic-GC.
2681 This has been fixed.
2682
Brett Cannone6539c42005-01-08 02:43:53 +00002683- _DummyThread objects in the threading module now delete self.__block that is
2684 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2685 lock primitives tend to be limited in number and thus should not be wasted on
2686 a _DummyThread object. Fixes bug #1089632.
2687
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002688- The imghdr module now detects Exif files.
2689
Raymond Hettinger6065d322004-12-20 23:51:53 +00002690- StringIO.truncate() now correctly adjusts the size attribute.
2691 (Bug #951915).
2692
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002693- locale.py now uses an updated locale alias table (built using
2694 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2695 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002696 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002697
Raymond Hettinger3557f422004-12-07 12:02:02 +00002698- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2699
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002700- the pickle module no longer accepts the deprecated None option in the
2701 args tuple returned by __reduce__().
2702
Brett Cannon84667c02004-12-07 03:25:18 +00002703- optparse now optionally imports gettext. This allows its use in setup.py.
2704
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002705- the pickle module no longer uses the deprecated bin parameter.
2706
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002707- the shelve module no longer uses the deprecated binary parameter.
2708
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002709- the pstats module no longer uses the deprecated ignore() method.
2710
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002711- the filecmp module no longer uses the deprecated use_statcache argument.
2712
Raymond Hettinger664347b2004-12-04 21:21:53 +00002713- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2714 extended or overridden by subclasses. Formerly, the subclassed method would
2715 be ignored by the rest of the module. (Bug #1078905).
2716
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002717- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002718 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002719
Walter Dörwald36733692004-12-22 12:50:50 +00002720- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2721 once when a size argument is given. This prevents a buffer overflow in the
2722 tokenizer with very long source lines.
2723
Barry Warsaw538561e2006-01-01 21:48:54 +00002724- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2725 immediately after creating the object, without any intervening
2726 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002727
Skip Montanaro05885812005-01-16 20:48:27 +00002728- The reconvert.quote function can now emit triple-quoted strings. The
2729 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002730
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002731- ``UserString.MutableString`` now supports negative indices in
2732 ``__setitem__`` and ``__delitem__``
2733
Greg Ward40407942005-03-05 02:53:17 +00002734- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2735 correctly.
2736
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002737- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2738 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2739 character even if the user has passed a size parameter to get a proper
2740 line ending. Remove the special handling of a "\r\n" that has been split
2741 between two lines.
2742
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002743- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2744 about illegal code points. The codec now supports PEP 293 style error
2745 handlers.
2746
Walter Dörwald78a78b02005-09-01 12:04:29 +00002747- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002748 from the input stream, so that the output is a byte string in the correct
2749 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002750
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002751- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2752 considering it exactly like a '*'.
2753
Walter Dörwald007f8df2005-10-09 19:42:27 +00002754- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2755 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002756
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002757- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2758
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002759- Patch #1413711: Certain patterns of differences were making difflib
2760 touch the recursion limit.
2761
Walter Dörwald58917a62006-03-31 15:26:22 +00002762- Bug #947906: An object oriented interface has been added to the calendar
2763 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002764 called as a script (e.g. via ``python -mcalendar``). Localized month and
2765 weekday names can be ouput (even if an exotic encoding is used) using
2766 special classes that use unicode.

Neal Norwitz602d3392006-03-31 08:21:40 +00002771- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2772 by using -mieee gcc option.
2773
Martin v. Löwis86d66262006-02-17 08:40:11 +00002774- Patch #1432345: Make python compile on DragonFly.
2775
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002776- Build support for Win64-AMD64 was added.
2777
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002778- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2779
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002780- Patch #881820: look for openpty and forkpty also in libbsd.
2781
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002782- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2783 The zlib module is now builtin on Windows.
2784
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002785- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2786
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002787- Bug #1189330: configure did not correctly determine the necessary
2788 value of LINKCC if python was built with GCC 4.0.
2789
Trent Mick8321b422005-07-26 02:29:21 +00002790- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2791 vulnerability in zlib 1.2.1 and 1.2.2.
2792
Brett Cannon08cd5982005-04-24 22:26:38 +00002793- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2794 flags that change binary compatibility. Changes were also made to
2795 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002796 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002797
Bob Ippolitoed233462005-03-29 13:47:59 +00002798- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2799 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2800 no longer exists). This configure patch makes things right.
2801
Martin v. Löwise2713be2005-03-08 15:03:08 +00002802- Bug #1158607: Build with --disable-unicode again.
2803
Brett Cannon46d96232005-02-16 00:07:19 +00002804- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2805 defined. Discovered as a result of not being able to build on OS X.
2806
Brett Cannon516592f2004-12-07 00:42:59 +00002807- setup.py now uses the directories specified in LDFLAGS using the -L option
2808 and in CPPFLAGS using the -I option for adding library and include
2809 directories, respectively, for compiling extension modules against. This has
2810 led to the core being compiled using the values in CPPFLAGS. It also removes
2811 the need for the special-casing of both DarwinPorts and Fink for darwin since
2812 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2813 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2814 Fink, ``-I/opt/local/include`` for DarwinPorts).
2815
Brett Cannon43802422005-02-10 20:48:03 +00002816- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2817 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2818 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2819 Closes bug #1096244. Thanks Gregory Bond.

2822-----
2823
Tim Petersc9d78aa2006-03-26 23:27:58 +00002824- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2825 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2826 is obtained via the ``PyObject_`` family, it must be released via the
2827 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2828 always been officially true, but when Python's small-object allocator was
2829 introduced, an attempt was made to cater to a few extension modules
2830 discovered at the time that obtained memory via ``PyObject_New`` but
2831 released it via ``PyMem_DEL``. It's years later, and if such code still
2832 exists it will fail now (probably with segfaults, but calling wrong
2833 low-level memory management functions can yield many symptoms).
2834
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002835- Added a C API for set and frozenset objects.
2836
Raymond Hettinger66517482004-12-03 11:45:13 +00002837- Removed PyRange_New().
2838
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002839- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2840 mapping argument now. This string is used as a mapping table. Byte values
2841 greater than the length of the string and 0xFFFE are treated as undefined
2842 mappings.
