Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000601- The return tuple from str.rpartition(sep) is (tail, sep, head) where
602 head is the original string if sep was not found.
603
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000604- Bug #1520864: unpacking singleton tuples in list comprehensions and
605 generator expressions (x for x, in ... ) works again. Fixing this problem
606 required changing the .pyc magic number. This means that .pyc files
607 generated before 2.5c2 will be regenerated.

719Core and builtins
720-----------------
721
Neal Norwitz24b6f202006-09-05 04:43:56 +0000722- Fix infinite recursion when subclassing long and overriding __hash__.
723
724- Fix concatenation (+=) of long strings.
725
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000726- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000727 compared equal or unequal to a string and a UnicodeDecodeError
728 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000729
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000730 Instead, the equal (==) and unequal (!=) comparison operators will
731 now issue a UnicodeWarning and interpret the two objects as
732 unequal. The UnicodeWarning can be filtered as desired using
733 the warning framework, e.g. silenced completely, turned into an
734 exception, logged, etc.
735
736 Note that compare operators other than equal and unequal will still
737 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000738
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000739- Fix segfault when doing string formatting on subclasses of long.
740
741- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
742 with new-style classes.
743
744- Fix bug related to __len__ functions returning negative values with
745 classic classes.
746
747- Patch #1538606, Fix __index__() clipping. There were some problems
748 discovered with the API and how integers that didn't fit into Py_ssize_t
749 were handled. This patch attempts to provide enough alternatives
750 to effectively use __index__.
751
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000752- Bug #1536021: __hash__ may now return long int; the final hash
753 value is obtained by invoking hash on the long int.
754
Thomas Hellerab1049c2006-08-08 17:37:00 +0000755- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000757- Bug #1535165: fixed a segfault in input() and raw_input() when
758 sys.stdin is closed.
759
Thomas Heller74d36f02006-08-04 18:17:40 +0000760- On Windows, the PyErr_Warn function is now exported from
761 the Python dll again.
762
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000763- Bug #1191458: tracing over for loops now produces a line event
764 on each iteration. Fixing this problem required changing the .pyc
765 magic number. This means that .pyc files generated before 2.5c1
766 will be regenerated.
767
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000768- Bug #1333982: string/number constants were inappropriately stored
769 in the byte code and co_consts even if they were not used, ie
770 immediately popped off the stack.
771
Georg Brandle9462c72006-08-04 18:03:37 +0000772- Fixed a reference-counting problem in property().

776-------
777
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000778- Fix a bug in the ``compiler`` package that caused invalid code to be
779 generated for generator expressions.
780
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000781- The distutils version has been changed to 2.5.0. The change to
782 keep it programmatically in sync with the Python version running
783 the code (introduced in 2.5b3) has been reverted. It will continue
784 to be maintained manually as static string literal.
785
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000786- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000787 and this cannot be converted to the required C type, an exception is
788 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000789 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000790
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000791- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000792 an exception.
793
Tim Peterscbdd3502006-09-05 01:47:53 +0000794- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000795 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000796 workarounds for clocks with low resolution, to stop the code yielding
797 duplicate UUIDs.
798
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000799- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
800 before raising SystemExit, allowing IDLE to honor quit() and exit().
801
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000802- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
803
Georg Brandl7a1af772006-08-14 21:55:28 +0000804- Patch #1536071: trace.py should now find the full module name of a
805 file correctly even on Windows.
806
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000807- logging's atexit hook now runs even if the rest of the module has
808 already been cleaned up.

835
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000836- Bug #1530559, struct.pack raises TypeError where it used to convert.
837 Passing float arguments to struct.pack when integers are expected
838 now triggers a DeprecationWarning.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000891- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000892 returned a long (see PEP 353).
893
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000894- Bug #1515471: string.replace() accepts character buffers again.

Neal Norwitz07aadb12006-07-30 06:55:48 +0000896- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
897 This provides the proper warning for struct.pack().
898 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().

Neal Norwitz0d62a062006-07-30 06:53:31 +0000900- Patch #1531113: Fix augmented assignment with yield expressions.
901 Also fix a SystemError when trying to assign to yield expressions.
902
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000903- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
904 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
905 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
906 excessive filesystem operations during imports.
907
Tim Petersbc24eee2006-07-27 01:14:53 +0000908- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
909 operations on signed longs that are formally undefined by C.
910 Unfortunately, at least one compiler now cares about that, so complicated
911 the code to make that compiler happy again.
912
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000913- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
914
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000915- Patch #1232023: Stop including current directory in search
916 path on Windows.
917
Neal Norwitze1fdb322006-07-21 05:32:28 +0000918- Fix some potential crashes found with failmalloc.
919
Neal Norwitze7563102006-07-17 01:00:16 +0000920- Fix warnings reported by Klocwork's static analysis tool.
921
Neal Norwitz84be93b2006-07-16 01:50:38 +0000922- Bug #1512814, Fix incorrect lineno's when code within a function
923 had more than 255 blank lines.
924
Georg Brandl9dceedb2006-07-12 15:31:17 +0000925- Patch #1521179: Python now accepts the standard options ``--help`` and
926 ``--version`` as well as ``/?`` on Windows.
927
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000928- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000929 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000930 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000931
Tim Peters112aad32006-07-19 00:03:19 +0000932- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000933 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000934 new ``sys._current_frames()`` returns a dictionary with one entry,
935 mapping the faux "thread id" 0 to the current frame.
936
Ronald Oussoren3075e162006-07-25 20:28:55 +0000937- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

941-------
942
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000943- Correction of patch #1455898: In the mbcs decoder, set final=False
944 for stream decoder, but final=True for the decode function.
945
Georg Brandl07fec3a2006-08-01 18:49:24 +0000946- os.urandom no longer masks unrelated exceptions like SystemExit or
947 KeyboardInterrupt.
948
Tim Peters4643c2f2006-08-10 22:45:34 +0000949- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000950 shutil.copytree on Windows
951
Georg Brandle34ac7c2006-07-30 11:07:23 +0000952- Bug #1002398: The documentation for os.path.sameopenfile now correctly
953 refers to file descriptors, not file objects.
954
Tim Peterscbdd3502006-09-05 01:47:53 +0000955- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000956 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000957 #1513611, and probably others.
958
Georg Brandledd9b0d2006-07-29 09:33:26 +0000959- Bug #1441397: The compiler module now recognizes module and function
960 docstrings correctly as it did in Python 2.4.
961
Tim Peters6f681472006-07-27 23:44:37 +0000962- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
963 lost that tests are sorted by name before being run. This rarely
964 matters for well-written tests, but can create baffling symptoms if
965 side effects from one test to the next affect outcomes. ``DocTestFinder``
966 has been changed to sort the list of tests it returns.
967
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000968- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000969 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000970
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000971- Bug #978833: Really close underlying socket in _socketobject.close.
972
Georg Brandldb232dc2006-08-20 13:15:43 +0000973- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
974 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000975
Georg Brandlcf0c1722006-07-26 07:23:32 +0000976- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
977 to recursive calls and call it with the failing package name.
978
Martin v. Löwis0b483032006-07-25 09:53:12 +0000979- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
980
Georg Brandlc13c34c2006-07-24 14:09:56 +0000981- Patch #1515343: Fix printing of deprecated string exceptions with a
982 value in the traceback module.
983
Greg Ward48fae7a2006-07-23 16:05:51 +0000984- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
985
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000986- Patch #1524429: Use repr() instead of backticks in Tkinter again.
987
Brett Cannoncaebe222006-07-18 04:41:36 +0000988- Bug #1520914: Change time.strftime() to accept a zero for any position in its
989 argument tuple. For arguments where zero is illegal, the value is forced to
990 the minimum value that is correct. This is to support an undocumented but
991 common way people used to fill in inconsequential information in the time
992 tuple pre-2.4.
993
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000994- Patch #1220874: Update the binhex module for Mach-O.
995
Barry Warsawb110bad2006-07-21 14:51:07 +0000996- The email package has improved RFC 2231 support, specifically for
997 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
998 (name*0=<blah>) parameter continuations. This may change the types of
999 values returned from email.message.Message.get_param() and friends.
1000 Specifically in some cases where non-encoded continuations were used,
1001 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1002 will just return the string (since non-encoded continuations don't have
1003 charset and language parts).
1004
1005 Also, whereas % values were decoded in all parameter continuations, they are
1006 now only decoded in encoded parameter parts.
1007
Ronald Oussoren3075e162006-07-25 20:28:55 +00001008- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1009
1010- Bug #1517996: IDLE now longer shows the default Tk menu when a
1011 path browser, class browser or debugger is the frontmost window on MacOS X
1012
Barry Warsaw00decd72006-07-27 23:43:15 +00001013- Patch #1520294: Support for getset and member descriptors in types.py,
1014 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1015 of an object against these built-in types and more importantly, for getting
1016 their docstrings printed in the interactive interpreter's help() function.

1020-----------------
1021
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001022- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1023 a socket operation on a socket with a timeout, the exception will be
1024 caught correctly. Previously, the exception was not caught.
1025
Thomas Heller1393d6a2006-07-28 21:43:20 +00001026- Patch #1529514: The _ctypes extension is now compiled on more
1027 openbsd target platforms.
1028
Tim Peters9cab5932006-07-28 00:30:00 +00001029- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1030 a memory leak, affecting pickles and deep copies.
1031
Tim Petersbc24eee2006-07-27 01:14:53 +00001032- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001033 Paul Eggert.
1034
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001035- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1036
Thomas Hellerce049a02006-07-14 17:51:14 +00001037- Patch #1521817: Index range checking on ctypes arrays containing
1038 exactly one element enabled again. This allows iterating over these
1039 arrays, without the need to check the array size before.
1040
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001041- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001042 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001043 /dev/null in certain cases; this is now fixed.
1044
Thomas Heller47d7a062006-07-12 08:43:47 +00001045- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1046 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001047
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001048- Because of a misspelled preprocessor symbol, ctypes was always
1049 compiled without thread support; this is now fixed.
1050
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001051- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1052 methods now allow their database parameter to be None as the
1053 sleepycat API allows.
1054
Matt Flemingec926502006-07-28 11:27:27 +00001055- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1056 bluetooth API compared with Linux and FreeBSD.
1057
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001058Tests
1059-----
1060
1061- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1062 how long the test file should take to play. Now accepts taking 2.93 secs
1063 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1064
Georg Brandl4793aa32006-07-28 18:31:39 +00001065- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1066 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1067 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001074Mac
1075---
1076
1077- PythonLauncher now works correctly when the path to the script contains
1078 characters that are treated specially by the shell (such as quotes).
1079
1080- Bug #1527397: PythonLauncher now launches scripts with the working directory
1081 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001082 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001083 expect.

1092-----------------
1093
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001094- Bug #1441486: The literal representation of -(sys.maxint - 1)
1095 again evaluates to a int object, not a long.
1096
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001097- Bug #1501934: The scope of global variables that are locally assigned
1098 using augmented assignment is now correctly determined.
1099
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001100- Bug #927248: Recursive method-wrapper objects can now safely
1101 be released.
1102
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001103- Bug #1417699: Reject locale-specific decimal point in float()
1104 and atof().
1105
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001106- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1107 omit a default "error" argument for NULL pointer. This allows
1108 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001109
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001110- Bug #1519018: 'as' is now validated properly in import statements.
1111
Neal Norwitz28746ab2006-07-09 22:14:42 +00001112- On 64 bit systems, int literals that use less than 64 bits are
1113 now ints rather than longs.
1114
Neal Norwitzed657552006-07-10 00:04:44 +00001115- Bug #1512814, Fix incorrect lineno's when code at module scope
1116 started after line 256.
1117
Tim Peters32a83612006-07-10 21:08:24 +00001118- New function ``sys._current_frames()`` returns a dict mapping thread
1119 id to topmost thread stack frame. This is for expert use, and is
1120 especially useful for debugging application deadlocks. The functionality
1121 was previously available in Fazal Majid's ``threadframe`` extension
1122 module, but it wasn't possible to do this in a wholly threadsafe way from
1123 an extension.

1129 VS 2003.
1130
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001131- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1132
Tim Peters32a83612006-07-10 21:08:24 +00001133- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001134 environment variable to be set in order to the SDK environment
1135 for finding the compiler, include files, etc.

1140
Thomas Woutersadd19112006-07-05 11:03:49 +00001141- string.Template() now correctly handles tuple-values. Previously,
1142 multi-value tuples would raise an exception and single-value tuples would
1143 be treated as the value they contain, instead.
1144
Martin v. Löwisede77f52006-07-03 13:01:35 +00001145- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1146 even if some data are received.
1147
Martin v. Löwis45482392006-07-03 12:28:58 +00001148- Bug #1267547: Put proper recursive setup.py call into the
1149 spec file generated by bdist_rpm.
1150
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001151- Bug #1514693: Update turtle's heading when switching between
1152 degrees and radians.
1153
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001154- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001155 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001156
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001157- Bug #1514703: Only setup canvas window in turtle when the canvas
1158 is created.
1159
Martin v. Löwis7596e832006-07-01 15:33:37 +00001160- Bug #1513223: .close() of a _socketobj now releases the underlying
1161 socket again, which then gets closed as it becomes unreferenced.
1162
Fred Drake10497c82006-06-29 02:57:48 +00001163- Bug #1504333: Make sgmllib support angle brackets in quoted
1164 attribute values.
1165
1166- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1167 sgmllib ('[' and ']' were not accepted).
1168
Georg Brandl1be63af2006-06-28 20:23:25 +00001169- Fix a bug in the turtle module's end_fill function.
1170
Brett Cannon53ab5b72006-06-22 16:49:14 +00001171- Bug #1510580: The 'warnings' module improperly required that a Warning
1172 category be either a types.ClassType and a subclass of Warning. The proper
1173 check is just that it is a subclass with Warning as the documentation states.
1174
Georg Brandlad29e632006-06-21 17:45:17 +00001175- The compiler module now correctly compiles the new try-except-finally
1176 statement (bug #1509132).
1177
Neal Norwitz60373cd2006-06-22 06:30:50 +00001178- The wsgiref package is now installed properly on Unix.
1179
Vinay Sajip28e57612006-07-01 10:45:20 +00001180- A bug was fixed in logging.config.fileConfig() which caused a crash on
1181 shutdown when fileConfig() was called multiple times.

Gerhard Häring762fbd32006-07-02 17:48:30 +00001183- The sqlite3 module did cut off data from the SQLite database at the first
1184 null character before sending it to a custom converter. This has been fixed
1185 now.

Tim Peters112aad32006-07-19 00:03:19 +00001190- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1191 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1192 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001193
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001194- Assigning None to pointer type fields in ctypes structures possible
1195 overwrote the wrong fields, this is fixed now.
1196
1197- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1198 on non-Windows platforms.
1199
1200- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1201 integer or long, without range checking.
1202
1203- Patch #1517790: It is now possible to use custom objects in the ctypes
1204 foreign function argtypes sequence as long as they provide a from_param
1205 method, no longer is it required that the object is a ctypes type.
1206
1207- The '_ctypes' extension module now works when Python is configured
1208 with the --without-threads option.
1209
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001210- Bug #1513646: os.access on Windows now correctly determines write
1211 access, again.
1212
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001213- Bug #1512695: cPickle.loads could crash if it was interrupted with
1214 a KeyboardInterrupt.
1215
Neal Norwitza12aa882006-07-06 06:45:08 +00001216- Bug #1296433: parsing XML with a non-default encoding and
1217 a CharacterDataHandler could crash the interpreter in pyexpat.
1218
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001219- Patch #1516912: improve Modules support for OpenVMS.

1225
Tim Peters32a83612006-07-10 21:08:24 +00001226- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001227 Previously, the slight difference could cause compilation errors of the
1228 'zlib' module on systems with more than one version of zlib.
1229
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001230- The MSI compileall step was fixed to also support a TARGETDIR
1231 with spaces in it.
1232
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001233- Bug #1517388: sqlite3.dll is now installed on Windows independent
1234 of Tcl/Tk.
1235
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001236- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001237 trying to be installed even though it's empty.

1262-----------------
1263
Georg Brandla56b9152006-06-19 06:35:54 +00001264- Patch #1507676: Error messages returned by invalid abstract object operations
1265 (such as iterating over an integer) have been improved and now include the
1266 type of the offending object to help with debugging.
1267
Brett Cannonea3912b2006-06-13 21:46:41 +00001268- Bug #992017: A classic class that defined a __coerce__() method that returned
1269 its arguments swapped would infinitely recurse and segfault the interpreter.
1270
Neal Norwitz909eb122006-06-12 02:13:21 +00001271- Fix the socket tests so they can be run concurrently.
1272
Neal Norwitzb9845e72006-06-12 02:11:18 +00001273- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001274 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001275
Brett Cannon22565aa2006-06-09 22:31:23 +00001276- Bug #532646: object.__call__() will continue looking for the __call__
1277 attribute on objects until one without one is found. This leads to recursion
1278 when you take a class and set its __call__ attribute to an instance of the
1279 class. Originally fixed for classic classes, but this fix is for new-style.
1280 Removes the infinite_rec_3 crasher.
1281
Georg Brandl24250812006-06-09 18:45:48 +00001282- The string and unicode methods startswith() and endswith() now accept
1283 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1284
Brett Cannonde3b0522006-06-08 17:00:45 +00001285- Buffer objects, at the C level, never used the char buffer
1286 implementation even when the char buffer for the wrapped object was
1287 explicitly requested (originally returned the read or write buffer).
1288 Now a TypeError is raised if the char buffer is not present but is
1289 requested.
1290
Georg Brandlddbaa662006-06-04 21:56:52 +00001291- Patch #1346214: Statements like "if 0: suite" are now again optimized
1292 away like they were in Python 2.4.
1293
Georg Brandlb7c8f542006-05-27 12:30:25 +00001294- Builtin exceptions are now full-blown new-style classes instead of
1295 instances pretending to be classes, which speeds up exception handling
1296 by about 80% in comparison to 2.5a2.
1297
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001298- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1299 Unicode 4.1.
1300
Georg Brandlf4ef1162006-05-26 18:03:31 +00001301- Patch #921466: sys.path_importer_cache is now used to cache valid and
1302 invalid file paths for the built-in import machinery which leads to
1303 fewer open calls on startup.
1304
Tim Peters696cf432006-05-24 21:10:40 +00001305- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1306 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1307 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1308 the number of input digits (it was and remains linear-time for bases
1309 2, 4, 8, 16 and 32).
1310
Tim Petersb713ec22006-05-23 18:45:30 +00001311- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1312 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1313 an integer close to ``sys.maxint``. This was repaired by patch
1314 #1335972, which also gives a nice speedup.
1315
Richard Jonescebbefc2006-05-23 18:28:17 +00001316- Patch #1337051: reduced size of frame objects.
1317
1318- PyErr_NewException now accepts a tuple of base classes as its
1319 "base" parameter.
1320
Richard Jones7c88dcc2006-05-23 10:37:38 +00001321- Patch #876206: function call speedup by retaining allocated frame
1322 objects.
1323
Georg Brandl7b90e162006-05-18 07:01:27 +00001324- Bug #1462152: file() now checks more thoroughly for invalid mode
1325 strings and removes a possible "U" before passing the mode to the
1326 C library function.
1327
Neal Norwitz1004a532006-05-15 07:17:23 +00001328- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1329
Neal Norwitz373f0a72006-05-15 07:04:36 +00001330- Bug #1487966: Fix SystemError with conditional expression in assignment
1331
Martin v. Löwis879768d2006-05-11 13:28:43 +00001332- WindowsError now has two error code attributes: errno, which carries
1333 the error values from errno.h, and winerror, which carries the error
1334 values from winerror.h. Previous versions put the winerror.h values
1335 (from GetLastError()) into the errno attribute.
1336
Martin v. Löwis77736712006-05-04 05:51:03 +00001337- Patch #1475845: Raise IndentationError for unexpected indent.
1338
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001339- Patch #1479181: split open() and file() from being aliases for each other.
1340
Tim Peters44bd9862006-06-01 13:49:23 +00001341- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1342 methods were always silently ignored by dictionaries when comparing keys.
1343 They are now passed through (except when using the C API function
1344 ``PyDict_GetItem()``, whose semantics did not change).
1345
1346- Bug #1456209: In some obscure cases it was possible for a class with a
1347 custom ``__eq__()`` method to confuse dict internals when class instances
1348 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1349 No, you don't have any code that did this ;-)

1357
Brett Cannon6ee7d012006-06-08 16:23:04 +00001358- Change binascii.hexlify to accept a read-only buffer instead of only a char
1359 buffer and actually follow its documentation.
1360
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001361- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1362
Nick Coghlanc649ec52006-05-29 12:43:05 +00001363- Patch #1478788 (modified version): The functional extension module has
1364 been renamed to _functools and a functools Python wrapper module added.
1365 This provides a home for additional function related utilities that are
1366 not specifically about functional programming. See PEP 309.
1367
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001368- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001372- Patch #1435422: zlib's compress and decompress objects now have a
1373 copy() method.
1374
Andrew MacIntyre92913322006-06-13 15:04:24 +00001375- Patch #1454481: thread stack size is now tunable at runtime for thread
1376 enabled builds on Windows and systems with Posix threads support.
1377
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001378- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1379 (up to the system limit of 32K characters).
1380
1381- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1382 As a result, these functions now raise WindowsError instead of OSError.
1383
Tim Peters7a822da2006-05-25 21:50:17 +00001384- ``time.clock()`` on Win64 should use the high-performance Windows
1385 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1386 Windows platforms).
1387
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001388- Calling Tk_Init twice is refused if the first call failed as that
1389 may deadlock.
1390
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001391- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1392 accept it without potentially using an uninitialized pointer.
1393
1394- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1395 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001401- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1402 parameter is supplied. [SF pybsddb bug #1477863]
1403
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001404- bsddb: the __len__ method of a DB object has been fixed to return correct
1405 results. It could previously incorrectly return 0 in some cases.
1406 Fixes SF bug 1493322 (pybsddb bug 1184012).
1407
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001408- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1409 aborts the db transaction safely when a modifier callback fails.
1410 Fixes SF python patch/bug #1408584.
1411
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001412- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001413 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001414 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1415 database calls that would previously deadlock. [SF python bug #775414]
1416
Vinay Sajip28e57612006-07-01 10:45:20 +00001417- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwisd8251432006-06-14 05:21:04 +00001444- Patch #1455898: The MBCS codec now supports the incremental mode for
1445 double-byte encodings.
1446
Tim Peters43898b42006-06-14 04:09:25 +00001447- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1448 guarantee that adjacent triples in the return list always describe
1449 non-adjacent blocks. Previously, a pair of matching blocks could end
1450 up being described by multiple adjacent triples that formed a partition
1451 of the matching pair.
1452
Greg Ward0e0c9f42006-06-11 16:24:11 +00001453- Bug #1498146: fix optparse to handle Unicode strings in option help,

1459 clarify docs.
1460
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001461- The wsgiref package has been added to the standard library.
1462
Nick Coghlan676725d2006-06-08 13:54:49 +00001463- The functions update_wrapper() and wraps() have been added to the functools
1464 module. These make it easier to copy relevant metadata from the original
1465 function when writing wrapper functions.
1466
Tim Petersd6a9eef2006-06-05 01:48:21 +00001467- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1468 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001469
Martin v. Löwis3f767792006-06-04 19:36:28 +00001470- Patch #1359618: Speed up charmap encoder by using a trie structure
1471 for lookup.
1472
Tim Petersd609b1a2006-06-02 23:22:51 +00001473- The functions in the ``pprint`` module now sort dictionaries by key
1474 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1475 if and only if its display required more than one line, although that
1476 wasn't documented. The new behavior increases predictability; e.g.,
1477 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1478
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001479- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1480 (thanks for J. J. Lee).
1481
Georg Brandl2b330372006-05-28 20:23:12 +00001482- Patch #1496206: improve urllib2 handling of passwords with respect to
1483 default HTTP and HTTPS ports.
1484
George Yoshidaf3c65de2006-05-28 16:39:09 +00001485- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1486
Bob Ippolito7298f272006-05-23 18:43:47 +00001487- Patch #1281707: speed up gzip.readline.
1488
Georg Brandlb89316f2006-05-17 15:51:16 +00001489- Patch #1180296: Two new functions were added to the locale module:
1490 format_string() to get the effect of "format % items" but locale-aware,
1491 and currency() to format a monetary number with currency sign.
1492
Georg Brandle3a25832006-05-17 14:56:04 +00001493- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1494 and several features added, such as speed and geometry control.
1495
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001496- Patch #1488881: add support for external file objects in bz2 compressed
1497 tarfiles.
1498
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001499- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1500 stdout arguments, making it possible to redirect input and output
1501 for remote debugging.
1502
1503- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1504 a couple of issues, notably handling of long file names using the
1505 GNU LONGNAME extension.
1506
1507- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1508 new flag when ``name`` is already the name of an option flag.
1509
1510- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1511 package.
1512
1513- Patch #1472854: make the rlcompleter.Completer class usable on non-
1514 UNIX platforms.
1515
1516- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1517
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001518- Bug #1472827: correctly escape newlines and tabs in attribute values in
1519 the saxutils.XMLGenerator class.

1548
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001549What's New in Python 2.5 alpha 2?
1550=================================
1551
1552*Release date: 27-APR-2006*
1553
1554Core and builtins
1555-----------------
1556
Thomas Heller1b046642006-04-18 18:51:06 +00001557- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1558 by converting these apis from macros into exported functions again:
1559
1560 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1561 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1562 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1563 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1564 PyRun_String Py_CompileString
1565
Martin v. Löwis45294a92006-04-18 06:24:08 +00001566- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1567
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001568- All uses of PyStructSequence_InitType have been changed to initialize
1569 the type objects only once, even if the interpreter is initialized
1570 multiple times.
1571
Neal Norwitz61546162006-04-14 05:20:28 +00001572- Bug #1454485, array.array('u') could crash the interpreter. This was
1573 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1574 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1575
1576- Py_UNICODE is unsigned. It was always documented as unsigned, but
1577 due to a bug had a signed value in previous versions.
1578
Tim Peters3a5e8b12006-04-11 01:44:07 +00001579- Patch #837242: ``id()`` of any Python object always gives a positive
1580 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1581 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001582 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001583 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001584
Tim Peters3a5e8b12006-04-11 01:44:07 +00001585 def __hash__(self):
1586 return id(self) # WRONG
1587
1588 because a hash result must be a (short) Python int but it was always
1589 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001590 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001591 was always usable as a hash value before this patch. That's no longer
1592 necessarily so.
1593
1594- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001595 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001596 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001597 #1454844)
1598
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001599- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1600 involving generators that have paused outside of any ``try`` or ``with``
1601 blocks. (In 2.5a1, a paused generator that was part of a reference
1602 cycle could not be garbage collected, regardless of whether it was
1603 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001604
Anthony Baxter51bcb682006-04-05 14:51:42 +00001605Extension Modules
1606-----------------
1607
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001608- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1609 is a macro.
1610
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001611- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1612 fails with an error condition.
1613
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001614- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1615
1616- Bug #1117761: bsddb.*open() no longer raises an exception when using
1617 the cachesize parameter.
1618
1619- Bug #1149413: bsddb.*open() no longer raises an exception when using
1620 a temporary db (file=None) with the 'n' flag to truncate on open.
1621
1622- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1623 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001624
Armin Rigoa9017c32006-04-19 11:50:27 +00001625- Patch #1062014: AF_UNIX sockets under Linux have a special
1626 abstract namespace that is now fully supported.
1627

1629-------
1630
Peter Astrand7d1d4362006-07-14 14:04:45 +00001631- Bug #1223937: subprocess.CalledProcessError reports the exit status
1632 of the process using the returncode attribute, instead of
1633 abusing errno.
1634
Tim Peters711bf302006-04-25 03:31:36 +00001635- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1636 a doctest to be skipped (the code is not run, and the expected output
1637 or exception is ignored).
1638
Nick Coghlanda2268f2006-04-24 04:37:15 +00001639- Fixed contextlib.nested to cope with exceptions being raised and
1640 caught inside exit handlers.
1641
Greg Wardab05edc2006-04-23 03:47:58 +00001642- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1643 hex, octal, or binary; add ``append_const`` action; keep going if
1644 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1645 added ``epilog`` for better help generation).
1646
Tim Peters21fbd572006-04-21 21:18:10 +00001647- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1648 called from a thread spawned as a side effect of importing a module.
1649
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001650- The pydoc module now supports documenting packages contained in
1651 .zip or .egg files.
1652
1653- The pkgutil module now has several new utility functions, such
1654 as ``walk_packages()`` to support working with packages that are either
1655 in the filesystem or zip files.
1656
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001657- The mailbox module can now modify and delete messages from
1658 mailboxes, in addition to simply reading them. Thanks to Gregory
1659 K. Johnson for writing the code, and to the 2005 Google Summer of
1660 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001661
Tim Petersc7605f22006-04-17 21:12:33 +00001662- The ``__del__`` method of class ``local`` in module ``_threading_local``
1663 returned before accomplishing any of its intended cleanup.
1664
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001665- Patch #790710: Add breakpoint command lists in pdb.
1666
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001667- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1668
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001669- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1670
Anthony Baxtere29002c2006-04-12 12:07:31 +00001671- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1672 Windows. Bug #1469163.
1673
Phillip J. Eby47032112006-04-11 01:07:43 +00001674- The warnings, linecache, inspect, traceback, site, and doctest modules
1675 were updated to work correctly with modules imported from zipfiles or
1676 via other PEP 302 __loader__ objects.
1677
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001678- Patch #1467770: Reduce usage of subprocess._active to processes which
1679 the application hasn't waited on.
1680
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001681- Patch #1462222: Fix Tix.Grid.
1682
Neal Norwitza31bf182006-04-09 03:35:43 +00001683- Fix exception when doing glob.glob('anything*/')
1684
Skip Montanaro262fb922006-04-21 02:31:07 +00001685- The pstats.Stats class accepts an optional stream keyword argument to
1686 direct output to an alternate file-like object.
1687
Anthony Baxter51bcb682006-04-05 14:51:42 +00001688Build
1689-----
1690
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001691- The Makefile now has a reindent target, which runs reindent.py on
1692 the library.
1693
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001694- Patch #1470875: Building Python with MS Free Compiler
1695
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001696- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001697
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001698- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1699 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001700 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001701 CXX from --with-cxx-main, see description in README.
1702
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001703- Patch #1429775: Link extension modules with the shared libpython.
1704
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001705- Fixed a libffi build problem on MIPS systems.
1706
Tim Peters8931ff12006-05-13 23:28:20 +00001707- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1708 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1709 and "%zu" for unsigned integers of type ``size_t``.
1710
Anthony Baxter51bcb682006-04-05 14:51:42 +00001711Tests
1712-----
1713
Nick Coghlanda2268f2006-04-24 04:37:15 +00001714- test_contextlib now checks contextlib.nested can cope with exceptions
1715 being raised and caught inside exit handlers.
1716
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001717- test_cmd_line now checks operation of the -m and -c command switches
1718
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001719- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1720 it separately and by hand. It also wasn't cleaning up its changes to
1721 the current Decimal context.
1722
Thomas Woutersabd08882006-04-26 15:53:30 +00001723- regrtest.py now has a -M option to run tests that test the new limits of
1724 containers, on 64-bit architectures. Running these tests is only sensible
1725 on 64-bit machines with more than two gigabytes of memory. The argument
1726 passed is the maximum amount of memory for the tests to use.

1735-------------
1736
Tim Petersb06d28c2006-05-12 01:57:59 +00001737- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1738
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001739- PEP 343: Added Context Types section to the library reference
1740 and attempted to bring other PEP 343 related documentation into
1741 line with the implementation and/or python-dev discussions.
1742
Tim Peters8dc73d22006-04-24 02:03:16 +00001743- Bug #1337990: clarified that ``doctest`` does not support examples
1744 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001747What's New in Python 2.5 alpha 1?
1748=================================
1749
Anthony Baxterebed3f62006-04-03 15:03:44 +00001750*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001751
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001752Core and builtins
1753-----------------
1754
Nick Coghlan43832302006-04-23 17:04:07 +00001755- PEP 338: -m command line switch now delegates to runpy.run_module
1756 allowing it to support modules in packages and zipfiles
1757
Martin v. Löwisc661b882006-04-20 04:54:23 +00001758- On Windows, .DLL is not an accepted file name extension for
1759 extension modules anymore; extensions are only found if they
1760 end in .PYD.
1761
Martin v. Löwisea62d252006-04-03 10:56:49 +00001762- Bug #1421664: sys.stderr.encoding is now set to the same value as
1763 sys.stdout.encoding.
1764
Neal Norwitz92e212f2006-04-03 04:48:37 +00001765- __import__ accepts keyword arguments.
1766
Georg Brandlccadf842006-03-31 18:54:53 +00001767- Patch #1460496: round() now accepts keyword arguments.
1768
Anthony Baxter262c00a2006-03-30 10:53:17 +00001769- Fixed bug #1459029 - unicode reprs were double-escaped.
1770
Hye-Shik Changd478f342006-03-23 12:32:36 +00001771- Patch #1396919: The system scope threads are reenabled on FreeBSD
1772 5.4 and later versions.
1773
Neal Norwitze98ccf62006-03-23 05:39:47 +00001774- Bug #1115379: Compiling a Unicode string with an encoding declaration
1775 now gives a SyntaxError.
1776
Georg Brandlabd1ff82006-03-18 07:59:59 +00001777- Previously, Python code had no easy way to access the contents of a
1778 cell object. Now, a ``cell_contents`` attribute has been added
1779 (closes patch #1170323).
1780
Tim Peterscf79aac2006-03-16 01:14:46 +00001781- Patch #1123430: Python's small-object allocator now returns an arena to
1782 the system ``free()`` when all memory within an arena becomes unused
1783 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1784 freed. Some applications will see a drop in virtual memory size now,
1785 especially long-running applications that, from time to time, temporarily
1786 use a large number of small objects. Note that when Python returns an
1787 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001788 platform C library will in turn return that memory to the operating system.
1789 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001790 appears to be effective at least on Microsoft C and gcc-based systems.
1791 Thanks to Evan Jones for hard work and patience.
1792
Georg Brandl533ff6f2006-03-08 18:09:27 +00001793- Patch #1434038: property() now uses the getter's docstring if there is
1794 no "doc" argument given. This makes it possible to legitimately use
1795 property() as a decorator to produce a read-only property.
1796
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001797- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1798 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1799 of requiring an int or long in slicing and a few other contexts, enabling
1800 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1801
Neal Norwitz995acdf2006-03-07 05:01:00 +00001802- Fixed various bugs reported by Coverity's Prevent tool.
1803
Brett Cannonbf364092006-03-01 04:25:17 +00001804- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1805 new exception base class, BaseException, which has a new message attribute.
1806 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1807 Raising a string exception now raises a DeprecationWarning.
1808
Thomas Woutersfb609f42006-02-28 16:37:25 +00001809- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1810 explicitly relative, using 'from .module import name' to mean 'from the same
1811 package as this module is in. Imports without dots still default to the
1812 old relative-then-absolute, unless 'from __future__ import
1813 absolute_import' is used.
1814
Brett Cannona7446e32006-02-27 23:39:10 +00001815- Properly check if 'warnings' raises an exception (usually when a filter set
1816 to "error" is triggered) when raising a warning for raising string
1817 exceptions.
1818
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001819- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001820 The name was removed from Include/code.h.
1821
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001822- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001823
Guido van Rossum1968ad32006-02-25 22:38:04 +00001824- Patch 1433928:
1825 - The copy module now "copies" function objects (as atomic objects).
1826 - dict.__getitem__ now looks for a __missing__ hook before raising
1827 KeyError.
1828
Tim Peters84ef21c2006-02-28 20:39:06 +00001829- PEP 343: with statement implemented. Needs ``from __future__ import
1830 with_statement``. Use of 'with' as a variable will generate a warning.
1831 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001832 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001833 The following objects have __context__ methods:
1834 - The built-in file type.
1835 - The thread.LockType type.
1836 - The following types defined by the threading module:
1837 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1838 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001839
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001840- Fix the encodings package codec search function to only search
1841 inside its own package. Fixes problem reported in patch #1433198.
1842
1843 Note: Codec packages should implement and register their own
1844 codec search function. PEP 100 has the details.
1845
Tim Peters9ea89d22006-06-04 03:26:02 +00001846- PEP 353: Using ``Py_ssize_t`` as the index type.
1847
1848- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1849 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1850 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1851 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1852 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001853
Neal Norwitzfc76d632006-01-10 06:03:13 +00001854- Patch #1400181, fix unicode string formatting to not use the locale.
1855 This is how string objects work. u'%f' could use , instead of .
1856 for the decimal point. Now both strings and unicode always use periods.
1857
Neal Norwitz671b9e32006-01-09 07:07:12 +00001858- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1859 configure would break checking curses.h.
1860
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001861- Bug #959576: The pwd module is now builtin. This allows Python to be
1862 built on UNIX platforms without $HOME set.
1863
Neal Norwitzc10978f2005-12-19 06:07:16 +00001864- Bug #1072182, fix some potential problems if characters are signed.
1865
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001866- Bug #889500, fix line number on SyntaxWarning for global declarations.
1867
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001868- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1869
Neal Norwitze7214a12005-12-18 05:03:17 +00001870- Support for converting hex strings to floats no longer works.
1871 This was not portable. float('0x3') now raises a ValueError.
1872
Barry Warsaw2a38a862005-12-18 01:27:35 +00001873- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001874 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001875 is now displayed in interactive prompt banner.
1876
Georg Brandlfa166682005-12-17 21:45:17 +00001877- Implementation of PEP 341 - Unification of try/except and try/finally.
1878 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001879 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001880
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001881- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1882 now encodes backslash correctly.
1883
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001884- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1885
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001886- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001887 and long longs.
1888
Neal Norwitz67715f02005-11-09 06:59:35 +00001889- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001890 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001891 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001892
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001893- Replaced most Unicode charmap codecs with new ones using the
1894 new Unicode translate string feature in the builtin charmap
1895 codec; the codecs were created from the mapping tables available
1896 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1897 encodings now include a mapping for the Apple logo)
1898
Tim Peterse3547fd2005-12-16 23:13:57 +00001899- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001900
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001901- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001902
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001903- A new AST parser implementation was completed. The abstract
1904 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001905 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001906
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001907- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001908 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1909
Neal Norwitz708e51a2005-10-03 04:48:15 +00001910- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1911
Neal Norwitz11bd1192005-10-03 00:54:56 +00001912- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1913 Provide a warning when a directory is passed on the command line.
1914
Neal Norwitz40d37812005-10-02 01:48:49 +00001915- Fix segfault with invalid coding.
1916
1917- SF bug #772896: unknown encoding results in MemoryError.
1918
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001919- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001920 supported a __len__() method which evaluated to False when the iterator
1921 was empty.
1922
Guido van Rossum630db602005-09-20 18:49:54 +00001923- On 64-bit platforms, when __len__() returns a value that cannot be
1924 represented as a C int, raise OverflowError.
1925
Skip Montanarof8948ca2005-09-19 03:54:46 +00001926- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001927 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001928
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001929- SF bug #893549: parsing keyword arguments was broken with a few format
1930 codes.
1931
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001932- Changes donated by Elemental Security to make it work on AIX 5.3
1933 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1934 bug #105470: test_pwd fails on 64bit system (Opteron).
1935
Guido van Rossum539c6622005-09-14 17:49:54 +00001936- Changes donated by Elemental Security to make it work on HP-UX 11 on
1937 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1938
Georg Brandl4550b8d2005-08-26 06:43:52 +00001939- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001940 (fixes bug #1119418).
1941
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001942- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1943
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001944- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1945 exceptions that cause a function to exit.
1946
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001947- The implementation of set() and frozenset() was revised to use its
1948 own internal data structure. Memory consumption is reduced by 1/3
1949 and there are modest speed-ups as well. The API is unchanged.
1950
Tim Petersde7990b2005-07-17 23:45:23 +00001951- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1952
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001953- SF bug #1229429: PyObject_CallMethod failed to decrement some
1954 reference counts in some error exit cases.
1955
Tim Petersecc6e6a2005-07-10 22:30:55 +00001956- SF bug #1185883: Python's small-object memory allocator took over
1957 a block managed by the platform C library whenever a realloc specified
1958 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001959 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001960 portable way to copy data from the C-managed block into Python's
1961 small-object space without risking a memory fault. Python's small-object
1962 realloc now leaves such blocks under the control of the platform C
1963 realloc.
1964
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001965- SF bug #1232517: An overflow error was not detected properly when
1966 attempting to convert a large float to an int in os.utime().
1967
Raymond Hettinger3296e692005-06-29 23:29:56 +00001968- SF bug #1224347: hex longs now print with lowercase letters just
1969 like their int counterparts.
1970
Michael W. Hudson188d4362005-06-20 16:52:57 +00001971- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1972 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1973 interpreter states; back out that fix and do a better job (see
1974 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1975 for a longer write-up of the problem).
1976
Michael W. Hudsondf888462005-06-03 14:41:55 +00001977- SF patch #1180995: marshal now uses a binary format by default when
1978 serializing floats.
1979
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001980- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1981 the routines that promise to produce IEEE 754 binary representations
1982 of floats now simply copy bytes around.
1983
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001984- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1985 278.
1986
Brett Cannonc3647ac2005-04-26 03:45:26 +00001987- patch #1109424: int, long, float, complex, and unicode now check for the
1988 proper magic slot for type conversions when subclassed. Previously the
1989 magic slot was ignored during conversion. Semantics now match the way
1990 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001991 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001992 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001993 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001994
Barry Warsawc8d907c2005-04-19 23:43:40 +00001995- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1996 NULL, now raise an AttributeError when attempting to set or delete the
1997 attribute. Previously a TypeError was raised, but this was inconsistent
1998 with the equivalent pure-Python implementation.
1999
Michael W. Hudson774479c2005-04-18 08:46:17 +00002000- It is now safe to call PyGILState_Release() before
2001 PyEval_InitThreads() (note that if there is reason to believe there
2002 are multiple threads around you still must call PyEval_InitThreads()
2003 before using the Python API; this fix is for extension modules that
2004 have no way of knowing if Python is multi-threaded yet).
2005
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002006- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2007 disabled caused a crash.
2008
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002009- Bug #1165306: instancemethod_new allowed the creation of a method
2010 with im_class == im_self == NULL, which caused a crash when called.
2011
Tim Petersecc6e6a2005-07-10 22:30:55 +00002012- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002013 fixes the crash seen in bug #1165761
2014
Raymond Hettinger96229b12005-03-11 06:49:40 +00002015- Added two new builtins, any() and all().
2016
Brett Cannon409d8f22005-03-05 06:47:57 +00002017- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002018 (e.g., ``class C(): pass`` is no longer a syntax error).
2019 Patch #1176012 added support to the 'parser' module and 'compiler' package
2020 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002021
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002022- Patch #1115086: Support PY_LONGLONG in structmember.
2023
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002024- Bug #1155938: new style classes did not check that __init__() was
2025 returning None.
2026
Tim Petersecc6e6a2005-07-10 22:30:55 +00002027- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002028 ('\') with a specific error message.
2029
Martin v. Löwisff232d72005-03-03 09:24:38 +00002030- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2031
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002032- Bug #1124295: the __name__ attribute of file objects was
2033 inadvertently made inaccessible in restricted mode.
2034
Tim Petersecc6e6a2005-07-10 22:30:55 +00002035- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002036 an ferror() call.
2037
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002038- min() and max() now support key= arguments with the same meaning as in
2039 list.sort().
2040
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002041- The peephole optimizer now performs simple constant folding in expressions:
2042 (2+3) --> (5).
2043
Raymond Hettingera422c342005-01-11 03:03:27 +00002044- set and frozenset objects can now be marshalled. SF #1098985.
2045
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002046- Bug #1077106: Poor argument checking could cause memory corruption
2047 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002048
Jeremy Hyltonab630502005-02-04 18:44:06 +00002049- The parser did not complain about future statements in illegal
2050 positions. It once again reports a syntax error if a future
2051 statement occurs after anything other than a doc string.
2052
Neil Schemenauercf52c072005-08-12 17:34:58 +00002053- Change the %s format specifier for str objects so that it returns a
2054 unicode instance if the argument is not an instance of basestring and
2055 calling __str__ on the argument returns a unicode instance.
2056
Tim Petersf4e69282006-02-27 17:15:31 +00002057- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2058 current thread state when the auto-GIL-state machinery knows about
2059 it (since the thread state is being deleted, continuing to remember it
2060 can't help, but can hurt if another thread happens to get created with
2061 the same thread id).

2194 the request code argument, which results in more C-like behaviour
2195 for large or negative values.
2196
Tim Petersecc6e6a2005-07-10 22:30:55 +00002197- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2206 available on the platform.
2207

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002237- the cPickle module no longer accepts the deprecated None option in the
2238 args tuple returned by __reduce__().
2239
Raymond Hettingerb2594052004-12-05 09:25:51 +00002240- itertools.islice() now accepts None for the start and step arguments.
2241 This allows islice() to work more readily with slices:
2242 islice(s.start, s.stop, s.step)
2243
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002244- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002253- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2254 been renamed to have only a single underscore prefix. This was done to
2255 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002256
Nick Coghlan43832302006-04-23 17:04:07 +00002257- PEP 338: new module runpy defines a run_module function to support
2258 executing modules which provide access to source code or a code object
2259 via the PEP 302 import mechanisms.
2260
Anthony Baxter93f5b932006-04-03 08:05:07 +00002261- The email module's parsedate_tz function now sets the daylight savings

2269 in attribute values.
2270
Anthony Baxterc51ee692006-04-01 00:57:31 +00002271- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002272 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002273 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002274 module will not be built.
2275
Tim Petersc17976e2006-04-01 00:26:53 +00002276- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2277 aren't officially supported here, and trying to use them will probably
2278 raise an exception some day. But dicts have been allowed, and "mostly
2279 worked", so support for them won't go away without warning.
2280
Georg Brandl338ef7d2006-03-31 18:42:16 +00002281- Bug #1445068: getpass.getpass() can now be given an explicit stream
2282 argument to specify where to write the prompt.
2283
Georg Brandl22ec80b2006-03-31 18:25:44 +00002284- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2299
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002300- email 4.0 package now integrated. This is largely the same as the email 3.0
2301 package that was included in Python 2.3, except that PEP 8 module names are
2302 now used (e.g. mail.message instead of email.Message). The MIME classes
2303 have been moved to a subpackage (e.g. email.mime.text instead of
2304 email.MIMEText). The old names are still supported for now. Several
2305 deprecated Message methods have been removed and lots of bugs have been
2306 fixed. More details can be found in the email package documentation.
2307
Walter Dörwald40108c92006-03-27 08:15:44 +00002308- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2309 (a subclass of tuple) that provides incremental decoders and encoders
2310 (a way to use stateful codecs without the stream API). Python functions
2311 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2312 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()

2396
2397 "The consensus of researchers in this area (at least as
2398 expressed at the NIST Hash Function Workshop 10/31/05),
2399 is that SHA-256 is a good choice for the time being, but
2400 that research should continue, and other alternatives may
2401 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002574
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002575- Bug #1110478: Revert os.environ.update to do putenv again.
2576
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002577- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2578

2580
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002581- Enhancements to the csv module:
2582
2583 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002584 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002585 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002586 + Dialect parameter parsing has been re-implemented to improve error
2587 reporting.
2588 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2589 dictates.
2590 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002591 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002592 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002593 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2594 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002595 + reader now allows \r characters to be quoted (previously it only allowed
2596 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002597 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002598 + Dialect classes passed to the module are no longer instantiated by
2599 the module before being parsed (the former validation scheme required
2600 this, but the mechanism was unreliable).
2601 + The dialect registry now contains instances of the internal
2602 C-coded dialect type, rather than references to python objects.
2603 + the internal c-coded dialect type is now immutable.
2604 + register_dialect now accepts the same keyword dialect specifications
2605 as the reader and writer, allowing the user to register dialects
2606 without first creating a dialect class.
2607 + a configurable limit to the size of parsed fields has been added -
2608 previously, an unmatched quote character could result in the entire
2609 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002610 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002611 the parser field size limit (returning the former limit). The initial
2612 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002613 + A line_num attribute has been added to the reader object, which tracks
2614 the number of lines read from the source iterator. This is not
2615 the same as the number of records returned, as records can span
2616 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002617 + reader and writer objects were not being registered with the cyclic-GC.
2618 This has been fixed.
2619
Brett Cannone6539c42005-01-08 02:43:53 +00002620- _DummyThread objects in the threading module now delete self.__block that is
2621 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2622 lock primitives tend to be limited in number and thus should not be wasted on
2623 a _DummyThread object. Fixes bug #1089632.
2624
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002625- The imghdr module now detects Exif files.
2626
Raymond Hettinger6065d322004-12-20 23:51:53 +00002627- StringIO.truncate() now correctly adjusts the size attribute.
2628 (Bug #951915).
2629
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002630- locale.py now uses an updated locale alias table (built using
2631 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2632 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002633 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002634
Raymond Hettinger3557f422004-12-07 12:02:02 +00002635- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2636
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002637- the pickle module no longer accepts the deprecated None option in the
2638 args tuple returned by __reduce__().
2639
Brett Cannon84667c02004-12-07 03:25:18 +00002640- optparse now optionally imports gettext. This allows its use in setup.py.
2641
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002642- the pickle module no longer uses the deprecated bin parameter.
2643
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002644- the shelve module no longer uses the deprecated binary parameter.
2645
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002646- the pstats module no longer uses the deprecated ignore() method.
2647
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002648- the filecmp module no longer uses the deprecated use_statcache argument.
2649
Raymond Hettinger664347b2004-12-04 21:21:53 +00002650- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2651 extended or overridden by subclasses. Formerly, the subclassed method would
2652 be ignored by the rest of the module. (Bug #1078905).
2653
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002654- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002655 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002656
Walter Dörwald36733692004-12-22 12:50:50 +00002657- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2658 once when a size argument is given. This prevents a buffer overflow in the
2659 tokenizer with very long source lines.
2660
Barry Warsaw538561e2006-01-01 21:48:54 +00002661- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2662 immediately after creating the object, without any intervening
2663 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002664
Skip Montanaro05885812005-01-16 20:48:27 +00002665- The reconvert.quote function can now emit triple-quoted strings. The
2666 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002667
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002668- ``UserString.MutableString`` now supports negative indices in
2669 ``__setitem__`` and ``__delitem__``
2670
Greg Ward40407942005-03-05 02:53:17 +00002671- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2672 correctly.
2673
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002674- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2675 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2676 character even if the user has passed a size parameter to get a proper
2677 line ending. Remove the special handling of a "\r\n" that has been split
2678 between two lines.
2679
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002680- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2681 about illegal code points. The codec now supports PEP 293 style error
2682 handlers.
2683
Walter Dörwald78a78b02005-09-01 12:04:29 +00002684- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002685 from the input stream, so that the output is a byte string in the correct
2686 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002687
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002688- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2689 considering it exactly like a '*'.
2690
Walter Dörwald007f8df2005-10-09 19:42:27 +00002691- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2692 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002693
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002694- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2695
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002696- Patch #1413711: Certain patterns of differences were making difflib
2697 touch the recursion limit.
2698
Walter Dörwald58917a62006-03-31 15:26:22 +00002699- Bug #947906: An object oriented interface has been added to the calendar
2700 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002701 called as a script (e.g. via ``python -mcalendar``). Localized month and
2702 weekday names can be ouput (even if an exotic encoding is used) using
2703 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002704
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002705Build
2706-----
2707
Neal Norwitz602d3392006-03-31 08:21:40 +00002708- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2709 by using -mieee gcc option.
2710

2712
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002713- Build support for Win64-AMD64 was added.
2714
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002715- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2716
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002717- Patch #881820: look for openpty and forkpty also in libbsd.
2718
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002719- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2720 The zlib module is now builtin on Windows.
2721
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002722- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2723
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002724- Bug #1189330: configure did not correctly determine the necessary
2725 value of LINKCC if python was built with GCC 4.0.
2726
Trent Mick8321b422005-07-26 02:29:21 +00002727- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2728 vulnerability in zlib 1.2.1 and 1.2.2.
2729
Brett Cannon08cd5982005-04-24 22:26:38 +00002730- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2731 flags that change binary compatibility. Changes were also made to
2732 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002733 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002734
Bob Ippolitoed233462005-03-29 13:47:59 +00002735- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2736 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2737 no longer exists). This configure patch makes things right.
2738
Martin v. Löwise2713be2005-03-08 15:03:08 +00002739- Bug #1158607: Build with --disable-unicode again.
2740
Brett Cannon46d96232005-02-16 00:07:19 +00002741- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2742 defined. Discovered as a result of not being able to build on OS X.
2743
Brett Cannon516592f2004-12-07 00:42:59 +00002744- setup.py now uses the directories specified in LDFLAGS using the -L option
2745 and in CPPFLAGS using the -I option for adding library and include
2746 directories, respectively, for compiling extension modules against. This has
2747 led to the core being compiled using the values in CPPFLAGS. It also removes
2748 the need for the special-casing of both DarwinPorts and Fink for darwin since
2749 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2750 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2751 Fink, ``-I/opt/local/include`` for DarwinPorts).
2752
Brett Cannon43802422005-02-10 20:48:03 +00002753- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2754 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2755 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2756 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002758C API
2759-----
2760
Tim Petersc9d78aa2006-03-26 23:27:58 +00002761- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2762 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2763 is obtained via the ``PyObject_`` family, it must be released via the
2764 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2765 always been officially true, but when Python's small-object allocator was
2766 introduced, an attempt was made to cater to a few extension modules
2767 discovered at the time that obtained memory via ``PyObject_New`` but
2768 released it via ``PyMem_DEL``. It's years later, and if such code still
2769 exists it will fail now (probably with segfaults, but calling wrong
2770 low-level memory management functions can yield many symptoms).
2771
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002772- Added a C API for set and frozenset objects.
2773
Raymond Hettinger66517482004-12-03 11:45:13 +00002774- Removed PyRange_New().
2775
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002776- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2777 mapping argument now. This string is used as a mapping table. Byte values
2778 greater than the length of the string and 0xFFFE are treated as undefined
2779 mappings.
