360
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000361- Make _PyGILState_NoteThreadState() static, it was not used anywhere
362 outside of pystate.c and should not be necessary.
363
Brett Cannon19d76c52006-09-09 07:18:44 +0000364- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
365 allows calling unicode() on exceptions classes directly to succeed.
366
Georg Brandlecab6232006-09-06 06:47:02 +0000367- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000382- The return tuple from str.rpartition(sep) is (tail, sep, head) where
383 head is the original string if sep was not found.
384
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000385- Bug #1520864: unpacking singleton tuples in list comprehensions and
386 generator expressions (x for x, in ... ) works again. Fixing this problem
387 required changing the .pyc magic number. This means that .pyc files
388 generated before 2.5c2 will be regenerated.

493
Neal Norwitz24b6f202006-09-05 04:43:56 +0000494- Fix infinite recursion when subclassing long and overriding __hash__.
495
496- Fix concatenation (+=) of long strings.
497
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000498- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000499 compared equal or unequal to a string and a UnicodeDecodeError
500 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000501
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000502 Instead, the equal (==) and unequal (!=) comparison operators will
503 now issue a UnicodeWarning and interpret the two objects as
504 unequal. The UnicodeWarning can be filtered as desired using
505 the warning framework, e.g. silenced completely, turned into an
506 exception, logged, etc.
507
508 Note that compare operators other than equal and unequal will still
509 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000510
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000511- Fix segfault when doing string formatting on subclasses of long.

514 with new-style classes.
515
516- Fix bug related to __len__ functions returning negative values with
517 classic classes.
518
519- Patch #1538606, Fix __index__() clipping. There were some problems
520 discovered with the API and how integers that didn't fit into Py_ssize_t
521 were handled. This patch attempts to provide enough alternatives
522 to effectively use __index__.
523
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000524- Bug #1536021: __hash__ may now return long int; the final hash
525 value is obtained by invoking hash on the long int.
526
Thomas Hellerab1049c2006-08-08 17:37:00 +0000527- Bug #1536786: buffer comparison could emit a RuntimeWarning.

530 sys.stdin is closed.
531
Thomas Heller74d36f02006-08-04 18:17:40 +0000532- On Windows, the PyErr_Warn function is now exported from
533 the Python dll again.
534
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000535- Bug #1191458: tracing over for loops now produces a line event
536 on each iteration. Fixing this problem required changing the .pyc
537 magic number. This means that .pyc files generated before 2.5c1
538 will be regenerated.
539
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000540- Bug #1333982: string/number constants were inappropriately stored
541 in the byte code and co_consts even if they were not used, ie
542 immediately popped off the stack.
543
Georg Brandle9462c72006-08-04 18:03:37 +0000544- Fixed a reference-counting problem in property().

Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000550- Fix a bug in the ``compiler`` package that caused invalid code to be
551 generated for generator expressions.
552
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000553- The distutils version has been changed to 2.5.0. The change to
554 keep it programmatically in sync with the Python version running
555 the code (introduced in 2.5b3) has been reverted. It will continue
556 to be maintained manually as static string literal.
557
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000558- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000559 and this cannot be converted to the required C type, an exception is
560 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000561 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000562
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000563- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000564 an exception.
565
Tim Peterscbdd3502006-09-05 01:47:53 +0000566- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000567 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000568 workarounds for clocks with low resolution, to stop the code yielding
569 duplicate UUIDs.
570
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000571- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
572 before raising SystemExit, allowing IDLE to honor quit() and exit().
573
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000574- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

600
Thomas Heller1ce433e2006-08-14 16:20:04 +0000601- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
602 '-no-stack-protector' compiler flag for OpenBSD has been removed.
603
Thomas Heller86720042006-08-14 11:17:48 +0000604- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
605 uses the _as_parameter_ attribute when objects are passed to foreign
606 function calls. The ctypes version number was changed to 1.0.1.
607
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000608- Bug #1530559, struct.pack raises TypeError where it used to convert.
609 Passing float arguments to struct.pack when integers are expected

Fred Drake53912162006-07-29 13:22:49 +0000655What's New in Python 2.5 beta 3?
656================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000657
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000658*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000659
660Core and builtins
661-----------------
662
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000663- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000664 returned a long (see PEP 353).
665
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000666- Bug #1515471: string.replace() accepts character buffers again.
667
Neal Norwitz07aadb12006-07-30 06:55:48 +0000668- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
669 This provides the proper warning for struct.pack().
670 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
671
Neal Norwitz0d62a062006-07-30 06:53:31 +0000672- Patch #1531113: Fix augmented assignment with yield expressions.
673 Also fix a SystemError when trying to assign to yield expressions.
674
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000675- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
676 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
677 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
678 excessive filesystem operations during imports.
679
Tim Petersbc24eee2006-07-27 01:14:53 +0000680- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
681 operations on signed longs that are formally undefined by C.
682 Unfortunately, at least one compiler now cares about that, so complicated
683 the code to make that compiler happy again.
684
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000685- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
686
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000687- Patch #1232023: Stop including current directory in search
688 path on Windows.
689
Neal Norwitze1fdb322006-07-21 05:32:28 +0000690- Fix some potential crashes found with failmalloc.
691
Neal Norwitze7563102006-07-17 01:00:16 +0000692- Fix warnings reported by Klocwork's static analysis tool.
693
Neal Norwitz84be93b2006-07-16 01:50:38 +0000694- Bug #1512814, Fix incorrect lineno's when code within a function
695 had more than 255 blank lines.
696
Georg Brandl9dceedb2006-07-12 15:31:17 +0000697- Patch #1521179: Python now accepts the standard options ``--help`` and
698 ``--version`` as well as ``/?`` on Windows.
699
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000700- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000701 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000702 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000703
Tim Peters112aad32006-07-19 00:03:19 +0000704- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000705 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000706 new ``sys._current_frames()`` returns a dictionary with one entry,
707 mapping the faux "thread id" 0 to the current frame.
708
Ronald Oussoren3075e162006-07-25 20:28:55 +0000709- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000710
Ronald Oussoren3075e162006-07-25 20:28:55 +0000711
Neal Norwitza1f10902006-07-12 07:28:29 +0000712Library
713-------
714
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000715- Correction of patch #1455898: In the mbcs decoder, set final=False
716 for stream decoder, but final=True for the decode function.
717
Georg Brandl07fec3a2006-08-01 18:49:24 +0000718- os.urandom no longer masks unrelated exceptions like SystemExit or
719 KeyboardInterrupt.
720
Tim Peters4643c2f2006-08-10 22:45:34 +0000721- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000722 shutil.copytree on Windows
723
Georg Brandle34ac7c2006-07-30 11:07:23 +0000724- Bug #1002398: The documentation for os.path.sameopenfile now correctly
725 refers to file descriptors, not file objects.
726
Tim Peterscbdd3502006-09-05 01:47:53 +0000727- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000728 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000729 #1513611, and probably others.
730
Georg Brandledd9b0d2006-07-29 09:33:26 +0000731- Bug #1441397: The compiler module now recognizes module and function
732 docstrings correctly as it did in Python 2.4.
733
Tim Peters6f681472006-07-27 23:44:37 +0000734- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
735 lost that tests are sorted by name before being run. This rarely
736 matters for well-written tests, but can create baffling symptoms if
737 side effects from one test to the next affect outcomes. ``DocTestFinder``
738 has been changed to sort the list of tests it returns.
739
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000740- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000741 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000742
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000743- Bug #978833: Really close underlying socket in _socketobject.close.
744
Georg Brandldb232dc2006-08-20 13:15:43 +0000745- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
746 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000747
Georg Brandlcf0c1722006-07-26 07:23:32 +0000748- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
749 to recursive calls and call it with the failing package name.
750
Martin v. Löwis0b483032006-07-25 09:53:12 +0000751- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
752
Georg Brandlc13c34c2006-07-24 14:09:56 +0000753- Patch #1515343: Fix printing of deprecated string exceptions with a
754 value in the traceback module.
755
Greg Ward48fae7a2006-07-23 16:05:51 +0000756- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
757
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000758- Patch #1524429: Use repr() instead of backticks in Tkinter again.
759
Brett Cannoncaebe222006-07-18 04:41:36 +0000760- Bug #1520914: Change time.strftime() to accept a zero for any position in its
761 argument tuple. For arguments where zero is illegal, the value is forced to
762 the minimum value that is correct. This is to support an undocumented but
763 common way people used to fill in inconsequential information in the time
764 tuple pre-2.4.
765
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000766- Patch #1220874: Update the binhex module for Mach-O.
767
Barry Warsawb110bad2006-07-21 14:51:07 +0000768- The email package has improved RFC 2231 support, specifically for
769 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
770 (name*0=<blah>) parameter continuations. This may change the types of
771 values returned from email.message.Message.get_param() and friends.
772 Specifically in some cases where non-encoded continuations were used,
773 get_param() used to return a 3-tuple of (None, None, string) whereas now it
774 will just return the string (since non-encoded continuations don't have
775 charset and language parts).
776
777 Also, whereas % values were decoded in all parameter continuations, they are
778 now only decoded in encoded parameter parts.
779
Ronald Oussoren3075e162006-07-25 20:28:55 +0000780- Bug #1517990: IDLE keybindings on MacOS X now work correctly
781
782- Bug #1517996: IDLE now longer shows the default Tk menu when a
783 path browser, class browser or debugger is the frontmost window on MacOS X
784
Barry Warsaw00decd72006-07-27 23:43:15 +0000785- Patch #1520294: Support for getset and member descriptors in types.py,
786 inspect.py, and pydoc.py. Specifically, this allows for querying the type
787 of an object against these built-in types and more importantly, for getting
788 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000791Extension Modules
792-----------------
793
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000794- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
795 a socket operation on a socket with a timeout, the exception will be
796 caught correctly. Previously, the exception was not caught.
797
Thomas Heller1393d6a2006-07-28 21:43:20 +0000798- Patch #1529514: The _ctypes extension is now compiled on more
799 openbsd target platforms.
800
Tim Peters9cab5932006-07-28 00:30:00 +0000801- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
802 a memory leak, affecting pickles and deep copies.
803
Tim Petersbc24eee2006-07-27 01:14:53 +0000804- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000805 Paul Eggert.
806
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000807- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
808
Thomas Hellerce049a02006-07-14 17:51:14 +0000809- Patch #1521817: Index range checking on ctypes arrays containing
810 exactly one element enabled again. This allows iterating over these
811 arrays, without the need to check the array size before.
812
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000813- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000814 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000815 /dev/null in certain cases; this is now fixed.
816
Thomas Heller47d7a062006-07-12 08:43:47 +0000817- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
818 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000819
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000820- Because of a misspelled preprocessor symbol, ctypes was always
821 compiled without thread support; this is now fixed.
822
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000823- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
824 methods now allow their database parameter to be None as the
825 sleepycat API allows.
826
Matt Flemingec926502006-07-28 11:27:27 +0000827- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
828 bluetooth API compared with Linux and FreeBSD.
829
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000830Tests
831-----
832
833- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
834 how long the test file should take to play. Now accepts taking 2.93 secs
835 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
836
Georg Brandl4793aa32006-07-28 18:31:39 +0000837- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
838 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
839 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000846Mac
847---
848
849- PythonLauncher now works correctly when the path to the script contains
850 characters that are treated specially by the shell (such as quotes).
851
852- Bug #1527397: PythonLauncher now launches scripts with the working directory
853 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000854 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000855 expect.

863Core and builtins
864-----------------
865
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000866- Bug #1441486: The literal representation of -(sys.maxint - 1)
867 again evaluates to a int object, not a long.
868
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000869- Bug #1501934: The scope of global variables that are locally assigned
870 using augmented assignment is now correctly determined.
871
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000872- Bug #927248: Recursive method-wrapper objects can now safely
873 be released.
874
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000875- Bug #1417699: Reject locale-specific decimal point in float()
876 and atof().
877
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000878- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
879 omit a default "error" argument for NULL pointer. This allows
880 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000881
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000882- Bug #1519018: 'as' is now validated properly in import statements.
883
Neal Norwitz28746ab2006-07-09 22:14:42 +0000884- On 64 bit systems, int literals that use less than 64 bits are
885 now ints rather than longs.
886
Neal Norwitzed657552006-07-10 00:04:44 +0000887- Bug #1512814, Fix incorrect lineno's when code at module scope
888 started after line 256.
889
Tim Peters32a83612006-07-10 21:08:24 +0000890- New function ``sys._current_frames()`` returns a dict mapping thread
891 id to topmost thread stack frame. This is for expert use, and is
892 especially useful for debugging application deadlocks. The functionality
893 was previously available in Fazal Majid's ``threadframe`` extension
894 module, but it wasn't possible to do this in a wholly threadsafe way from
895 an extension.

Martin v. Löwis8d656812006-07-10 07:23:48 +0000906 environment variable to be set in order to the SDK environment
907 for finding the compiler, include files, etc.
908

910
Nick Coghlan2d792252006-07-06 13:47:18 +0000911- warnings.py now ignores ImportWarning by default
912
Thomas Woutersadd19112006-07-05 11:03:49 +0000913- string.Template() now correctly handles tuple-values. Previously,
914 multi-value tuples would raise an exception and single-value tuples would
915 be treated as the value they contain, instead.
916
Martin v. Löwisede77f52006-07-03 13:01:35 +0000917- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
918 even if some data are received.
919

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000927 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000928
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000929- Bug #1514703: Only setup canvas window in turtle when the canvas
930 is created.
931
Martin v. Löwis7596e832006-07-01 15:33:37 +0000932- Bug #1513223: .close() of a _socketobj now releases the underlying
933 socket again, which then gets closed as it becomes unreferenced.
934
Fred Drake10497c82006-06-29 02:57:48 +0000935- Bug #1504333: Make sgmllib support angle brackets in quoted
936 attribute values.
937
938- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
939 sgmllib ('[' and ']' were not accepted).

942
Brett Cannon53ab5b72006-06-22 16:49:14 +0000943- Bug #1510580: The 'warnings' module improperly required that a Warning
944 category be either a types.ClassType and a subclass of Warning. The proper
945 check is just that it is a subclass with Warning as the documentation states.
946
Georg Brandlad29e632006-06-21 17:45:17 +0000947- The compiler module now correctly compiles the new try-except-finally
948 statement (bug #1509132).
949
Neal Norwitz60373cd2006-06-22 06:30:50 +0000950- The wsgiref package is now installed properly on Unix.
951
Vinay Sajip28e57612006-07-01 10:45:20 +0000952- A bug was fixed in logging.config.fileConfig() which caused a crash on
953 shutdown when fileConfig() was called multiple times.
954
Gerhard Häring762fbd32006-07-02 17:48:30 +0000955- The sqlite3 module did cut off data from the SQLite database at the first
956 null character before sending it to a custom converter. This has been fixed
957 now.

960-----------------
961
Tim Peters112aad32006-07-19 00:03:19 +0000962- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
963 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
964 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000965
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000966- Assigning None to pointer type fields in ctypes structures possible
967 overwrote the wrong fields, this is fixed now.
968
969- Fixed a segfault in _ctypes when ctypes.wintypes were imported
970 on non-Windows platforms.
971
972- Bug #1518190: The ctypes.c_void_p constructor now accepts any
973 integer or long, without range checking.
974
975- Patch #1517790: It is now possible to use custom objects in the ctypes
976 foreign function argtypes sequence as long as they provide a from_param
977 method, no longer is it required that the object is a ctypes type.
978
979- The '_ctypes' extension module now works when Python is configured
980 with the --without-threads option.
981
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000982- Bug #1513646: os.access on Windows now correctly determines write
983 access, again.
984
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000985- Bug #1512695: cPickle.loads could crash if it was interrupted with

987
Neal Norwitza12aa882006-07-06 06:45:08 +0000988- Bug #1296433: parsing XML with a non-default encoding and
989 a CharacterDataHandler could crash the interpreter in pyexpat.
990

Martin v. Löwisd73168d2006-07-14 09:58:55 +0000996- Automate Windows build process for the Win64 SSL module.
997
Tim Peters32a83612006-07-10 21:08:24 +0000998- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000999 Previously, the slight difference could cause compilation errors of the
1000 'zlib' module on systems with more than one version of zlib.
1001
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001002- The MSI compileall step was fixed to also support a TARGETDIR
1003 with spaces in it.

1033Core and builtins
1034-----------------
1035
Georg Brandla56b9152006-06-19 06:35:54 +00001036- Patch #1507676: Error messages returned by invalid abstract object operations
1037 (such as iterating over an integer) have been improved and now include the
1038 type of the offending object to help with debugging.
1039
Brett Cannonea3912b2006-06-13 21:46:41 +00001040- Bug #992017: A classic class that defined a __coerce__() method that returned
1041 its arguments swapped would infinitely recurse and segfault the interpreter.
1042
Neal Norwitz909eb122006-06-12 02:13:21 +00001043- Fix the socket tests so they can be run concurrently.
1044
Neal Norwitzb9845e72006-06-12 02:11:18 +00001045- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001046 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001047
Brett Cannon22565aa2006-06-09 22:31:23 +00001048- Bug #532646: object.__call__() will continue looking for the __call__
1049 attribute on objects until one without one is found. This leads to recursion
1050 when you take a class and set its __call__ attribute to an instance of the
1051 class. Originally fixed for classic classes, but this fix is for new-style.
1052 Removes the infinite_rec_3 crasher.
1053
Georg Brandl24250812006-06-09 18:45:48 +00001054- The string and unicode methods startswith() and endswith() now accept
1055 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1056
Brett Cannonde3b0522006-06-08 17:00:45 +00001057- Buffer objects, at the C level, never used the char buffer
1058 implementation even when the char buffer for the wrapped object was
1059 explicitly requested (originally returned the read or write buffer).
1060 Now a TypeError is raised if the char buffer is not present but is
1061 requested.
1062
Georg Brandlddbaa662006-06-04 21:56:52 +00001063- Patch #1346214: Statements like "if 0: suite" are now again optimized
1064 away like they were in Python 2.4.
1065
Georg Brandlb7c8f542006-05-27 12:30:25 +00001066- Builtin exceptions are now full-blown new-style classes instead of
1067 instances pretending to be classes, which speeds up exception handling
1068 by about 80% in comparison to 2.5a2.
1069
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001070- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1071 Unicode 4.1.
1072
Georg Brandlf4ef1162006-05-26 18:03:31 +00001073- Patch #921466: sys.path_importer_cache is now used to cache valid and
1074 invalid file paths for the built-in import machinery which leads to
1075 fewer open calls on startup.
1076
Tim Peters696cf432006-05-24 21:10:40 +00001077- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1078 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1079 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1080 the number of input digits (it was and remains linear-time for bases
1081 2, 4, 8, 16 and 32).
1082
Tim Petersb713ec22006-05-23 18:45:30 +00001083- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1084 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1085 an integer close to ``sys.maxint``. This was repaired by patch
1086 #1335972, which also gives a nice speedup.
1087
Richard Jonescebbefc2006-05-23 18:28:17 +00001088- Patch #1337051: reduced size of frame objects.
1089
1090- PyErr_NewException now accepts a tuple of base classes as its
1091 "base" parameter.
1092
Richard Jones7c88dcc2006-05-23 10:37:38 +00001093- Patch #876206: function call speedup by retaining allocated frame
1094 objects.
1095
Georg Brandl7b90e162006-05-18 07:01:27 +00001096- Bug #1462152: file() now checks more thoroughly for invalid mode
1097 strings and removes a possible "U" before passing the mode to the
1098 C library function.
1099
Neal Norwitz1004a532006-05-15 07:17:23 +00001100- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1101
Neal Norwitz373f0a72006-05-15 07:04:36 +00001102- Bug #1487966: Fix SystemError with conditional expression in assignment
1103
Martin v. Löwis879768d2006-05-11 13:28:43 +00001104- WindowsError now has two error code attributes: errno, which carries
1105 the error values from errno.h, and winerror, which carries the error
1106 values from winerror.h. Previous versions put the winerror.h values
1107 (from GetLastError()) into the errno attribute.
1108
Martin v. Löwis77736712006-05-04 05:51:03 +00001109- Patch #1475845: Raise IndentationError for unexpected indent.
1110
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001111- Patch #1479181: split open() and file() from being aliases for each other.
1112
Tim Peters44bd9862006-06-01 13:49:23 +00001113- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1114 methods were always silently ignored by dictionaries when comparing keys.
1115 They are now passed through (except when using the C API function
1116 ``PyDict_GetItem()``, whose semantics did not change).
1117
1118- Bug #1456209: In some obscure cases it was possible for a class with a
1119 custom ``__eq__()`` method to confuse dict internals when class instances
1120 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1121 No, you don't have any code that did this ;-)

Brett Cannon6ee7d012006-06-08 16:23:04 +00001130- Change binascii.hexlify to accept a read-only buffer instead of only a char
1131 buffer and actually follow its documentation.
1132
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001133- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1134
Nick Coghlanc649ec52006-05-29 12:43:05 +00001135- Patch #1478788 (modified version): The functional extension module has
1136 been renamed to _functools and a functools Python wrapper module added.
1137 This provides a home for additional function related utilities that are
1138 not specifically about functional programming. See PEP 309.
1139
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001140- Patch #1493701: performance enhancements for struct module.

1148 enabled builds on Windows and systems with Posix threads support.
1149
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001150- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1151 (up to the system limit of 32K characters).
1152
1153- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1154 As a result, these functions now raise WindowsError instead of OSError.
1155
Tim Peters7a822da2006-05-25 21:50:17 +00001156- ``time.clock()`` on Win64 should use the high-performance Windows
1157 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1158 Windows platforms).
1159
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001160- Calling Tk_Init twice is refused if the first call failed as that
1161 may deadlock.
1162
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001163- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1164 accept it without potentially using an uninitialized pointer.
1165
1166- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1167 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1177 results. It could previously incorrectly return 0 in some cases.
1178 Fixes SF bug 1493322 (pybsddb bug 1184012).
1179
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001180- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1181 aborts the db transaction safely when a modifier callback fails.
1182 Fixes SF python patch/bug #1408584.
1183
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001184- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001185 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001186 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1187 database calls that would previously deadlock. [SF python bug #775414]

1198 functions.
1199
Martin v. Löwis3798da02006-06-17 18:44:27 +00001200- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001202- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001203 Tkinter.BaseWidget.
1204
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001205- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1208 classes.
1209
Georg Brandl83cc0d02006-06-14 08:50:03 +00001210- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1211 mime.types file for determining MIME types.
1212
Georg Brandl2605ca82006-06-14 06:08:31 +00001213- Bug #1339007: Shelf objects now don't raise an exception in their
1214 __del__ method when initialization failed.
1215
Martin v. Löwisd8251432006-06-14 05:21:04 +00001216- Patch #1455898: The MBCS codec now supports the incremental mode for
1217 double-byte encodings.
1218
Tim Peters43898b42006-06-14 04:09:25 +00001219- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1220 guarantee that adjacent triples in the return list always describe
1221 non-adjacent blocks. Previously, a pair of matching blocks could end
1222 up being described by multiple adjacent triples that formed a partition
1223 of the matching pair.
1224
Greg Ward0e0c9f42006-06-11 16:24:11 +00001225- Bug #1498146: fix optparse to handle Unicode strings in option help,
1226 description, and epilog.
1227
Greg Wardd1c797e2006-06-11 14:42:41 +00001228- Bug #1366250: minor optparse documentation error.
1229
Greg Ward7f547402006-06-11 00:40:49 +00001230- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1231 clarify docs.
1232
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001233- The wsgiref package has been added to the standard library.
1234
Nick Coghlan676725d2006-06-08 13:54:49 +00001235- The functions update_wrapper() and wraps() have been added to the functools
1236 module. These make it easier to copy relevant metadata from the original
1237 function when writing wrapper functions.
1238
Tim Petersd6a9eef2006-06-05 01:48:21 +00001239- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1240 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001241
Martin v. Löwis3f767792006-06-04 19:36:28 +00001242- Patch #1359618: Speed up charmap encoder by using a trie structure
1243 for lookup.
1244
Tim Petersd609b1a2006-06-02 23:22:51 +00001245- The functions in the ``pprint`` module now sort dictionaries by key
1246 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1247 if and only if its display required more than one line, although that
1248 wasn't documented. The new behavior increases predictability; e.g.,
1249 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1250
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001251- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1252 (thanks for J. J. Lee).
1253
Georg Brandl2b330372006-05-28 20:23:12 +00001254- Patch #1496206: improve urllib2 handling of passwords with respect to
1255 default HTTP and HTTPS ports.
1256
George Yoshidaf3c65de2006-05-28 16:39:09 +00001257- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1258
Bob Ippolito7298f272006-05-23 18:43:47 +00001259- Patch #1281707: speed up gzip.readline.
1260
Georg Brandlb89316f2006-05-17 15:51:16 +00001261- Patch #1180296: Two new functions were added to the locale module:
1262 format_string() to get the effect of "format % items" but locale-aware,
1263 and currency() to format a monetary number with currency sign.
1264
Georg Brandle3a25832006-05-17 14:56:04 +00001265- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1266 and several features added, such as speed and geometry control.
1267
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001268- Patch #1488881: add support for external file objects in bz2 compressed
1269 tarfiles.
1270
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001271- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1272 stdout arguments, making it possible to redirect input and output
1273 for remote debugging.
1274
1275- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1276 a couple of issues, notably handling of long file names using the
1277 GNU LONGNAME extension.
1278
1279- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1280 new flag when ``name`` is already the name of an option flag.
1281
1282- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1283 package.
1284
1285- Patch #1472854: make the rlcompleter.Completer class usable on non-
1286 UNIX platforms.
1287
1288- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1289
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001290- Bug #1472827: correctly escape newlines and tabs in attribute values in
1291 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001321What's New in Python 2.5 alpha 2?

1323
1324*Release date: 27-APR-2006*
1325
1326Core and builtins
1327-----------------
1328
Thomas Heller1b046642006-04-18 18:51:06 +00001329- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1330 by converting these apis from macros into exported functions again:
1331
1332 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1333 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1334 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1335 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1336 PyRun_String Py_CompileString
1337
Martin v. Löwis45294a92006-04-18 06:24:08 +00001338- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1339
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001340- All uses of PyStructSequence_InitType have been changed to initialize
1341 the type objects only once, even if the interpreter is initialized
1342 multiple times.
1343
Neal Norwitz61546162006-04-14 05:20:28 +00001344- Bug #1454485, array.array('u') could crash the interpreter. This was
1345 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1346 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1347
1348- Py_UNICODE is unsigned. It was always documented as unsigned, but
1349 due to a bug had a signed value in previous versions.
1350
Tim Peters3a5e8b12006-04-11 01:44:07 +00001351- Patch #837242: ``id()`` of any Python object always gives a positive
1352 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1353 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001354 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001355 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001356
Tim Peters3a5e8b12006-04-11 01:44:07 +00001357 def __hash__(self):
1358 return id(self) # WRONG
1359
1360 because a hash result must be a (short) Python int but it was always
1361 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001362 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001363 was always usable as a hash value before this patch. That's no longer
1364 necessarily so.
1365
1366- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001367 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001368 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001369 #1454844)
1370
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001371- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1372 involving generators that have paused outside of any ``try`` or ``with``
1373 blocks. (In 2.5a1, a paused generator that was part of a reference
1374 cycle could not be garbage collected, regardless of whether it was
1375 paused in a ``try`` or ``with`` block.)

1382
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001383- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1384 fails with an error condition.
1385
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001386- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

1388- Bug #1117761: bsddb.*open() no longer raises an exception when using
1389 the cachesize parameter.
1390
1391- Bug #1149413: bsddb.*open() no longer raises an exception when using
1392 a temporary db (file=None) with the 'n' flag to truncate on open.
1393
1394- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1395 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001396
Armin Rigoa9017c32006-04-19 11:50:27 +00001397- Patch #1062014: AF_UNIX sockets under Linux have a special
1398 abstract namespace that is now fully supported.

1405 abusing errno.
1406
Tim Peters711bf302006-04-25 03:31:36 +00001407- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1408 a doctest to be skipped (the code is not run, and the expected output
1409 or exception is ignored).
1410
Nick Coghlanda2268f2006-04-24 04:37:15 +00001411- Fixed contextlib.nested to cope with exceptions being raised and
1412 caught inside exit handlers.
1413
Greg Wardab05edc2006-04-23 03:47:58 +00001414- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1415 hex, octal, or binary; add ``append_const`` action; keep going if
1416 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1417 added ``epilog`` for better help generation).
1418
Tim Peters21fbd572006-04-21 21:18:10 +00001419- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1420 called from a thread spawned as a side effect of importing a module.
1421
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001422- The pydoc module now supports documenting packages contained in
1423 .zip or .egg files.
1424
1425- The pkgutil module now has several new utility functions, such
1426 as ``walk_packages()`` to support working with packages that are either
1427 in the filesystem or zip files.
1428
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001429- The mailbox module can now modify and delete messages from
1430 mailboxes, in addition to simply reading them. Thanks to Gregory
1431 K. Johnson for writing the code, and to the 2005 Google Summer of
1432 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001433
Tim Petersc7605f22006-04-17 21:12:33 +00001434- The ``__del__`` method of class ``local`` in module ``_threading_local``
1435 returned before accomplishing any of its intended cleanup.
1436
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001437- Patch #790710: Add breakpoint command lists in pdb.

1442
Anthony Baxtere29002c2006-04-12 12:07:31 +00001443- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1444 Windows. Bug #1469163.
1445
Phillip J. Eby47032112006-04-11 01:07:43 +00001446- The warnings, linecache, inspect, traceback, site, and doctest modules
1447 were updated to work correctly with modules imported from zipfiles or
1448 via other PEP 302 __loader__ objects.
1449
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001450- Patch #1467770: Reduce usage of subprocess._active to processes which

1462
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001463- The Makefile now has a reindent target, which runs reindent.py on
1464 the library.
1465

1471 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001472 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001473 CXX from --with-cxx-main, see description in README.
1474

1478
Tim Peters8931ff12006-05-13 23:28:20 +00001479- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1480 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1481 and "%zu" for unsigned integers of type ``size_t``.
1482
Anthony Baxter51bcb682006-04-05 14:51:42 +00001483Tests
1484-----
1485
Nick Coghlanda2268f2006-04-24 04:37:15 +00001486- test_contextlib now checks contextlib.nested can cope with exceptions
1487 being raised and caught inside exit handlers.
1488
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001489- test_cmd_line now checks operation of the -m and -c command switches
1490
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001491- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1492 it separately and by hand. It also wasn't cleaning up its changes to
1493 the current Decimal context.
1494
Thomas Woutersabd08882006-04-26 15:53:30 +00001495- regrtest.py now has a -M option to run tests that test the new limits of
1496 containers, on 64-bit architectures. Running these tests is only sensible
1497 on 64-bit machines with more than two gigabytes of memory. The argument
1498 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001509- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1510
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001511- PEP 343: Added Context Types section to the library reference
1512 and attempted to bring other PEP 343 related documentation into
1513 line with the implementation and/or python-dev discussions.
1514
Tim Peters8dc73d22006-04-24 02:03:16 +00001515- Bug #1337990: clarified that ``doctest`` does not support examples
1516 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001519What's New in Python 2.5 alpha 1?
1520=================================
1521
Anthony Baxterebed3f62006-04-03 15:03:44 +00001522*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001523
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001524Core and builtins
1525-----------------
1526
Nick Coghlan43832302006-04-23 17:04:07 +00001527- PEP 338: -m command line switch now delegates to runpy.run_module
1528 allowing it to support modules in packages and zipfiles
1529
Martin v. Löwisc661b882006-04-20 04:54:23 +00001530- On Windows, .DLL is not an accepted file name extension for
1531 extension modules anymore; extensions are only found if they
1532 end in .PYD.
1533
Martin v. Löwisea62d252006-04-03 10:56:49 +00001534- Bug #1421664: sys.stderr.encoding is now set to the same value as
1535 sys.stdout.encoding.
1536
Neal Norwitz92e212f2006-04-03 04:48:37 +00001537- __import__ accepts keyword arguments.
1538
Georg Brandlccadf842006-03-31 18:54:53 +00001539- Patch #1460496: round() now accepts keyword arguments.
1540
Anthony Baxter262c00a2006-03-30 10:53:17 +00001541- Fixed bug #1459029 - unicode reprs were double-escaped.
1542
Hye-Shik Changd478f342006-03-23 12:32:36 +00001543- Patch #1396919: The system scope threads are reenabled on FreeBSD
1544 5.4 and later versions.
1545
Neal Norwitze98ccf62006-03-23 05:39:47 +00001546- Bug #1115379: Compiling a Unicode string with an encoding declaration
1547 now gives a SyntaxError.
1548
Georg Brandlabd1ff82006-03-18 07:59:59 +00001549- Previously, Python code had no easy way to access the contents of a
1550 cell object. Now, a ``cell_contents`` attribute has been added
1551 (closes patch #1170323).
1552
Tim Peterscf79aac2006-03-16 01:14:46 +00001553- Patch #1123430: Python's small-object allocator now returns an arena to
1554 the system ``free()`` when all memory within an arena becomes unused
1555 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1556 freed. Some applications will see a drop in virtual memory size now,
1557 especially long-running applications that, from time to time, temporarily
1558 use a large number of small objects. Note that when Python returns an
1559 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001560 platform C library will in turn return that memory to the operating system.
1561 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001562 appears to be effective at least on Microsoft C and gcc-based systems.
1563 Thanks to Evan Jones for hard work and patience.
1564
Georg Brandl533ff6f2006-03-08 18:09:27 +00001565- Patch #1434038: property() now uses the getter's docstring if there is
1566 no "doc" argument given. This makes it possible to legitimately use
1567 property() as a decorator to produce a read-only property.
1568
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001569- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1570 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1571 of requiring an int or long in slicing and a few other contexts, enabling
1572 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1573
Neal Norwitz995acdf2006-03-07 05:01:00 +00001574- Fixed various bugs reported by Coverity's Prevent tool.
1575
Brett Cannonbf364092006-03-01 04:25:17 +00001576- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1577 new exception base class, BaseException, which has a new message attribute.
1578 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1579 Raising a string exception now raises a DeprecationWarning.
1580
Thomas Woutersfb609f42006-02-28 16:37:25 +00001581- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1582 explicitly relative, using 'from .module import name' to mean 'from the same
1583 package as this module is in. Imports without dots still default to the
1584 old relative-then-absolute, unless 'from __future__ import
1585 absolute_import' is used.
1586
Brett Cannona7446e32006-02-27 23:39:10 +00001587- Properly check if 'warnings' raises an exception (usually when a filter set
1588 to "error" is triggered) when raising a warning for raising string
1589 exceptions.
1590
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001591- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001592 The name was removed from Include/code.h.
1593
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001594- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001595
Guido van Rossum1968ad32006-02-25 22:38:04 +00001596- Patch 1433928:
1597 - The copy module now "copies" function objects (as atomic objects).
1598 - dict.__getitem__ now looks for a __missing__ hook before raising
1599 KeyError.
1600
Tim Peters84ef21c2006-02-28 20:39:06 +00001601- PEP 343: with statement implemented. Needs ``from __future__ import
1602 with_statement``. Use of 'with' as a variable will generate a warning.
1603 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001604 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001605 The following objects have __context__ methods:
1606 - The built-in file type.
1607 - The thread.LockType type.
1608 - The following types defined by the threading module:
1609 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1610 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001611
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001612- Fix the encodings package codec search function to only search
1613 inside its own package. Fixes problem reported in patch #1433198.
1614
1615 Note: Codec packages should implement and register their own
1616 codec search function. PEP 100 has the details.
1617
Tim Peters9ea89d22006-06-04 03:26:02 +00001618- PEP 353: Using ``Py_ssize_t`` as the index type.
1619
1620- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1621 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1622 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1623 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1624 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001625
Neal Norwitzfc76d632006-01-10 06:03:13 +00001626- Patch #1400181, fix unicode string formatting to not use the locale.
1627 This is how string objects work. u'%f' could use , instead of .
1628 for the decimal point. Now both strings and unicode always use periods.
1629
Neal Norwitz671b9e32006-01-09 07:07:12 +00001630- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1631 configure would break checking curses.h.
1632
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001633- Bug #959576: The pwd module is now builtin. This allows Python to be
1634 built on UNIX platforms without $HOME set.
1635
Neal Norwitzc10978f2005-12-19 06:07:16 +00001636- Bug #1072182, fix some potential problems if characters are signed.
1637
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001638- Bug #889500, fix line number on SyntaxWarning for global declarations.
1639
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001640- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1641
Neal Norwitze7214a12005-12-18 05:03:17 +00001642- Support for converting hex strings to floats no longer works.
1643 This was not portable. float('0x3') now raises a ValueError.
1644
Barry Warsaw2a38a862005-12-18 01:27:35 +00001645- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001646 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001647 is now displayed in interactive prompt banner.
1648
Georg Brandlfa166682005-12-17 21:45:17 +00001649- Implementation of PEP 341 - Unification of try/except and try/finally.
1650 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001651 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001652
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001653- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1654 now encodes backslash correctly.
1655
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001656- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1657
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001658- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001659 and long longs.
1660
Neal Norwitz67715f02005-11-09 06:59:35 +00001661- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001662 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001663 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001664
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001665- Replaced most Unicode charmap codecs with new ones using the
1666 new Unicode translate string feature in the builtin charmap
1667 codec; the codecs were created from the mapping tables available
1668 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1669 encodings now include a mapping for the Apple logo)
1670
Tim Peterse3547fd2005-12-16 23:13:57 +00001671- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001672
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001673- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001674
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001675- A new AST parser implementation was completed. The abstract
1676 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001677 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001678
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001679- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001680 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1681
Neal Norwitz708e51a2005-10-03 04:48:15 +00001682- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1683
Neal Norwitz11bd1192005-10-03 00:54:56 +00001684- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1685 Provide a warning when a directory is passed on the command line.
1686
Neal Norwitz40d37812005-10-02 01:48:49 +00001687- Fix segfault with invalid coding.
1688
1689- SF bug #772896: unknown encoding results in MemoryError.
1690
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001691- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001692 supported a __len__() method which evaluated to False when the iterator
1693 was empty.
1694
Guido van Rossum630db602005-09-20 18:49:54 +00001695- On 64-bit platforms, when __len__() returns a value that cannot be
1696 represented as a C int, raise OverflowError.
1697
Skip Montanarof8948ca2005-09-19 03:54:46 +00001698- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001699 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001700
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001701- SF bug #893549: parsing keyword arguments was broken with a few format
1702 codes.
1703
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001704- Changes donated by Elemental Security to make it work on AIX 5.3
1705 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1706 bug #105470: test_pwd fails on 64bit system (Opteron).
1707
Guido van Rossum539c6622005-09-14 17:49:54 +00001708- Changes donated by Elemental Security to make it work on HP-UX 11 on
1709 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1710
Georg Brandl4550b8d2005-08-26 06:43:52 +00001711- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001712 (fixes bug #1119418).
1713
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001714- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1715
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001716- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1717 exceptions that cause a function to exit.
1718
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001719- The implementation of set() and frozenset() was revised to use its
1720 own internal data structure. Memory consumption is reduced by 1/3
1721 and there are modest speed-ups as well. The API is unchanged.
1722
Tim Petersde7990b2005-07-17 23:45:23 +00001723- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1724
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001725- SF bug #1229429: PyObject_CallMethod failed to decrement some
1726 reference counts in some error exit cases.
1727
Tim Petersecc6e6a2005-07-10 22:30:55 +00001728- SF bug #1185883: Python's small-object memory allocator took over
1729 a block managed by the platform C library whenever a realloc specified
1730 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001731 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001732 portable way to copy data from the C-managed block into Python's
1733 small-object space without risking a memory fault. Python's small-object
1734 realloc now leaves such blocks under the control of the platform C
1735 realloc.
1736
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001737- SF bug #1232517: An overflow error was not detected properly when
1738 attempting to convert a large float to an int in os.utime().
1739
Raymond Hettinger3296e692005-06-29 23:29:56 +00001740- SF bug #1224347: hex longs now print with lowercase letters just
1741 like their int counterparts.
1742
Michael W. Hudson188d4362005-06-20 16:52:57 +00001743- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1744 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1745 interpreter states; back out that fix and do a better job (see
1746 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1747 for a longer write-up of the problem).
1748
Michael W. Hudsondf888462005-06-03 14:41:55 +00001749- SF patch #1180995: marshal now uses a binary format by default when
1750 serializing floats.
1751
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001752- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1753 the routines that promise to produce IEEE 754 binary representations
1754 of floats now simply copy bytes around.
1755
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001756- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1757 278.
1758
Brett Cannonc3647ac2005-04-26 03:45:26 +00001759- patch #1109424: int, long, float, complex, and unicode now check for the
1760 proper magic slot for type conversions when subclassed. Previously the
1761 magic slot was ignored during conversion. Semantics now match the way
1762 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001763 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001764 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001765 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001766
Barry Warsawc8d907c2005-04-19 23:43:40 +00001767- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1768 NULL, now raise an AttributeError when attempting to set or delete the
1769 attribute. Previously a TypeError was raised, but this was inconsistent
1770 with the equivalent pure-Python implementation.
1771
Michael W. Hudson774479c2005-04-18 08:46:17 +00001772- It is now safe to call PyGILState_Release() before
1773 PyEval_InitThreads() (note that if there is reason to believe there
1774 are multiple threads around you still must call PyEval_InitThreads()

Anthony Baxterc51ee692006-04-01 00:57:31 +00002043- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002044 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002045 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002046 module will not be built.
2047
Tim Petersc17976e2006-04-01 00:26:53 +00002048- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2049 aren't officially supported here, and trying to use them will probably
2050 raise an exception some day. But dicts have been allowed, and "mostly
2051 worked", so support for them won't go away without warning.
2052
Georg Brandl338ef7d2006-03-31 18:42:16 +00002053- Bug #1445068: getpass.getpass() can now be given an explicit stream
2054 argument to specify where to write the prompt.
2055
Georg Brandl22ec80b2006-03-31 18:25:44 +00002056- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2062 key to be used for signing the uploaded code.
2063
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002064- Queue.Queue objects now support .task_done() and .join() methods
2065 to make it easier to monitor when daemon threads have completed
2066 processing all enqueued tasks. Patch #1455676.
2067
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002068- popen2.Popen objects now preserve the command in a .cmd attribute.
2069
Thomas Hellerc61c0492006-03-22 10:09:27 +00002070- Added the ctypes ffi package.
2071
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002072- email 4.0 package now integrated. This is largely the same as the email 3.0
2073 package that was included in Python 2.3, except that PEP 8 module names are
2074 now used (e.g. mail.message instead of email.Message). The MIME classes
2075 have been moved to a subpackage (e.g. email.mime.text instead of
2076 email.MIMEText). The old names are still supported for now. Several
2077 deprecated Message methods have been removed and lots of bugs have been
2078 fixed. More details can be found in the email package documentation.
2079
Walter Dörwald40108c92006-03-27 08:15:44 +00002080- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2081 (a subclass of tuple) that provides incremental decoders and encoders
2082 (a way to use stateful codecs without the stream API). Python functions
2083 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2084 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2085 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002086
Walter Dörwald067db482006-03-15 22:17:27 +00002087- Patch #1359365: Calling next() on a closed StringIO.String object raises
2088 a ValueError instead of a StopIteration now (like file and cString.String do).
2089 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2090 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002091
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002092- A regrtest option -w was added to re-run failed tests in verbose mode.

2095 interpreter to exit.
2096
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002097- The function get_count() has been added to the gc module, and gc.collect()
2098 grew an optional 'generation' argument.
2099
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002100- A library msilib to generate Windows Installer files, and a distutils

2160 LoadError as documented, instead of IOError. For compatibility,
2161 LoadError subclasses IOError.
2162

Tim Peterse3547fd2005-12-16 23:13:57 +00002164 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2165 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2166 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2167 Ronald L. Rivest offered this advice for Python:
2168
2169 "The consensus of researchers in this area (at least as
2170 expressed at the NIST Hash Function Workshop 10/31/05),
2171 is that SHA-256 is a good choice for the time being, but
2172 that research should continue, and other alternatives may
2173 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002174
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002175- Added a subset of Fredrik Lundh's ElementTree package. Available

2228 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002229 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002230

2246 parameter, but uses the usual "kwargs=None".
2247
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002248- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2268 Bug #1224621.
2269
Raymond Hettinger68c04532005-06-10 11:05:19 +00002270- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002271 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002272 the generate_tokens() function now accepts a callable argument that
2273 terminates by raising StopIteration.
2274

2279
Skip Montanaro174dd222005-05-14 20:54:16 +00002280- Patch #1120353: The xmlrpclib module provides better, more transparent,

2283 class at all.
2284
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002285- distutils.commands.upload was added to support uploading distribution

2331
Raymond Hettingerbab41432005-02-05 01:31:19 +00002332- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2333
Guido van Rossumd0641422005-02-03 15:01:24 +00002334- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2335 disables recursive traversal through instance attributes, which can
2336 be exploited in various ways.
2337
Tim Peterse3547fd2005-12-16 23:13:57 +00002338- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002339 flags on the HTTP listening socket.
2340
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002341- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2342 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2343
Fred Drakefbdeaad2006-07-29 16:56:15 +00002344- Patches #893642, #1039083: add allow_none, encoding arguments to
2345 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002346

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002349- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2350
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002351- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2352
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002353- Enhancements to the csv module:
2354
2355 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002356 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002357 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002358 + Dialect parameter parsing has been re-implemented to improve error
2359 reporting.
2360 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2361 dictates.
2362 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002363 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002364 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002365 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2366 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002367 + reader now allows \r characters to be quoted (previously it only allowed
2368 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002369 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002370 + Dialect classes passed to the module are no longer instantiated by
2371 the module before being parsed (the former validation scheme required
2372 this, but the mechanism was unreliable).
2373 + The dialect registry now contains instances of the internal
2374 C-coded dialect type, rather than references to python objects.
2375 + the internal c-coded dialect type is now immutable.
2376 + register_dialect now accepts the same keyword dialect specifications
2377 as the reader and writer, allowing the user to register dialects
2378 without first creating a dialect class.
2379 + a configurable limit to the size of parsed fields has been added -
2380 previously, an unmatched quote character could result in the entire
2381 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002382 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002383 the parser field size limit (returning the former limit). The initial
2384 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002385 + A line_num attribute has been added to the reader object, which tracks
2386 the number of lines read from the source iterator. This is not
2387 the same as the number of records returned, as records can span
2388 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002389 + reader and writer objects were not being registered with the cyclic-GC.
2390 This has been fixed.
2391
Brett Cannone6539c42005-01-08 02:43:53 +00002392- _DummyThread objects in the threading module now delete self.__block that is
2393 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2394 lock primitives tend to be limited in number and thus should not be wasted on
2395 a _DummyThread object. Fixes bug #1089632.
2396
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002397- The imghdr module now detects Exif files.
2398
Raymond Hettinger6065d322004-12-20 23:51:53 +00002399- StringIO.truncate() now correctly adjusts the size attribute.
2400 (Bug #951915).
2401
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002402- locale.py now uses an updated locale alias table (built using
2403 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2404 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002405 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002406
Raymond Hettinger3557f422004-12-07 12:02:02 +00002407- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2408
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002409- the pickle module no longer accepts the deprecated None option in the
2410 args tuple returned by __reduce__().
2411
Brett Cannon84667c02004-12-07 03:25:18 +00002412- optparse now optionally imports gettext. This allows its use in setup.py.
2413
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002414- the pickle module no longer uses the deprecated bin parameter.
2415
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002416- the shelve module no longer uses the deprecated binary parameter.
2417
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002418- the pstats module no longer uses the deprecated ignore() method.
2419
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002420- the filecmp module no longer uses the deprecated use_statcache argument.
2421
Raymond Hettinger664347b2004-12-04 21:21:53 +00002422- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2423 extended or overridden by subclasses. Formerly, the subclassed method would
2424 be ignored by the rest of the module. (Bug #1078905).
2425
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002426- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002427 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002428
Walter Dörwald36733692004-12-22 12:50:50 +00002429- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2430 once when a size argument is given. This prevents a buffer overflow in the
2431 tokenizer with very long source lines.
2432
Barry Warsaw538561e2006-01-01 21:48:54 +00002433- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2434 immediately after creating the object, without any intervening
2435 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002436
Skip Montanaro05885812005-01-16 20:48:27 +00002437- The reconvert.quote function can now emit triple-quoted strings. The
2438 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002439
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002440- ``UserString.MutableString`` now supports negative indices in
2441 ``__setitem__`` and ``__delitem__``
2442
Greg Ward40407942005-03-05 02:53:17 +00002443- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2444 correctly.
2445
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002446- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2447 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2448 character even if the user has passed a size parameter to get a proper
2449 line ending. Remove the special handling of a "\r\n" that has been split
2450 between two lines.
2451
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002452- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2453 about illegal code points. The codec now supports PEP 293 style error
2454 handlers.
2455
Walter Dörwald78a78b02005-09-01 12:04:29 +00002456- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002457 from the input stream, so that the output is a byte string in the correct
2458 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002459
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002460- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2461 considering it exactly like a '*'.
2462
Walter Dörwald007f8df2005-10-09 19:42:27 +00002463- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2464 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002465
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002466- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2467
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002468- Patch #1413711: Certain patterns of differences were making difflib
2469 touch the recursion limit.
2470
Walter Dörwald58917a62006-03-31 15:26:22 +00002471- Bug #947906: An object oriented interface has been added to the calendar
2472 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002473 called as a script (e.g. via ``python -mcalendar``). Localized month and
2474 weekday names can be ouput (even if an exotic encoding is used) using
2475 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002476
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002477Build
2478-----
2479
Neal Norwitz602d3392006-03-31 08:21:40 +00002480- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2481 by using -mieee gcc option.
2482
Martin v. Löwis86d66262006-02-17 08:40:11 +00002483- Patch #1432345: Make python compile on DragonFly.
2484
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002485- Build support for Win64-AMD64 was added.
2486
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002487- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2488
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002489- Patch #881820: look for openpty and forkpty also in libbsd.
2490
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002491- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2492 The zlib module is now builtin on Windows.
2493
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002494- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2495
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002496- Bug #1189330: configure did not correctly determine the necessary
2497 value of LINKCC if python was built with GCC 4.0.
2498
Trent Mick8321b422005-07-26 02:29:21 +00002499- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2500 vulnerability in zlib 1.2.1 and 1.2.2.
2501
Brett Cannon08cd5982005-04-24 22:26:38 +00002502- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2503 flags that change binary compatibility. Changes were also made to
2504 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002505 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002506
Bob Ippolitoed233462005-03-29 13:47:59 +00002507- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2508 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2509 no longer exists). This configure patch makes things right.
2510
Martin v. Löwise2713be2005-03-08 15:03:08 +00002511- Bug #1158607: Build with --disable-unicode again.
2512
Brett Cannon46d96232005-02-16 00:07:19 +00002513- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2514 defined. Discovered as a result of not being able to build on OS X.
2515
Brett Cannon516592f2004-12-07 00:42:59 +00002516- setup.py now uses the directories specified in LDFLAGS using the -L option
2517 and in CPPFLAGS using the -I option for adding library and include
2518 directories, respectively, for compiling extension modules against. This has
2519 led to the core being compiled using the values in CPPFLAGS. It also removes
2520 the need for the special-casing of both DarwinPorts and Fink for darwin since
2521 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2522 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2523 Fink, ``-I/opt/local/include`` for DarwinPorts).
2524
Brett Cannon43802422005-02-10 20:48:03 +00002525- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2526 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2527 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2528 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002530C API
2531-----
2532
Tim Petersc9d78aa2006-03-26 23:27:58 +00002533- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2534 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2535 is obtained via the ``PyObject_`` family, it must be released via the
2536 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2537 always been officially true, but when Python's small-object allocator was
2538 introduced, an attempt was made to cater to a few extension modules
2539 discovered at the time that obtained memory via ``PyObject_New`` but
2540 released it via ``PyMem_DEL``. It's years later, and if such code still
2541 exists it will fail now (probably with segfaults, but calling wrong
2542 low-level memory management functions can yield many symptoms).
2543
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002544- Added a C API for set and frozenset objects.
2545
Raymond Hettinger66517482004-12-03 11:45:13 +00002546- Removed PyRange_New().
2547
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002548- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2549 mapping argument now. This string is used as a mapping table. Byte values
2550 greater than the length of the string and 0xFFFE are treated as undefined
2551 mappings.
