72
Georg Brandlec6c2df2006-09-11 09:38:35 +000073- Make _PyGILState_NoteThreadState() static, it was not used anywhere

92
Neal Norwitzdac090d2006-09-05 03:53:08 +000093- Bug #1520864: unpacking singleton tuples in list comprehensions and
94 generator expressions (x for x, in ... ) works again. Fixing this problem

366Core and builtins
367-----------------
368
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000369- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000370 compared equal or unequal to a string and a UnicodeDecodeError
371 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000372
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000373 Instead, the equal (==) and unequal (!=) comparison operators will
374 now issue a UnicodeWarning and interpret the two objects as
375 unequal. The UnicodeWarning can be filtered as desired using
376 the warning framework, e.g. silenced completely, turned into an
377 exception, logged, etc.
378
379 Note that compare operators other than equal and unequal will still
380 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000381
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000382- Fix segfault when doing string formatting on subclasses of long.
383
384- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
385 with new-style classes.
386
387- Fix bug related to __len__ functions returning negative values with
388 classic classes.
389
390- Patch #1538606, Fix __index__() clipping. There were some problems
391 discovered with the API and how integers that didn't fit into Py_ssize_t
392 were handled. This patch attempts to provide enough alternatives
393 to effectively use __index__.
394
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000395- Bug #1536021: __hash__ may now return long int; the final hash
396 value is obtained by invoking hash on the long int.
397
Thomas Hellerab1049c2006-08-08 17:37:00 +0000398- Bug #1536786: buffer comparison could emit a RuntimeWarning.
399
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000400- Bug #1535165: fixed a segfault in input() and raw_input() when
401 sys.stdin is closed.
402
Thomas Heller74d36f02006-08-04 18:17:40 +0000403- On Windows, the PyErr_Warn function is now exported from
404 the Python dll again.
405
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000406- Bug #1191458: tracing over for loops now produces a line event
407 on each iteration. Fixing this problem required changing the .pyc
408 magic number. This means that .pyc files generated before 2.5c1
409 will be regenerated.
410
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000411- Bug #1333982: string/number constants were inappropriately stored
412 in the byte code and co_consts even if they were not used, ie
413 immediately popped off the stack.
414
Georg Brandle9462c72006-08-04 18:03:37 +0000415- Fixed a reference-counting problem in property().

419-------
420
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000421- Fix a bug in the ``compiler`` package that caused invalid code to be
422 generated for generator expressions.
423
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000424- The distutils version has been changed to 2.5.0. The change to
425 keep it programmatically in sync with the Python version running
426 the code (introduced in 2.5b3) has been reverted. It will continue
427 to be maintained manually as static string literal.
428
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000429- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000430 and this cannot be converted to the required C type, an exception is
431 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000432 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000433
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000434- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000435 an exception.
436
Tim Petersc10c9d02006-09-05 02:18:09 +0000437- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000438 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000439 workarounds for clocks with low resolution, to stop the code yielding
440 duplicate UUIDs.
441
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000442- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
443 before raising SystemExit, allowing IDLE to honor quit() and exit().
444
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000445- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
446
Georg Brandl7a1af772006-08-14 21:55:28 +0000447- Patch #1536071: trace.py should now find the full module name of a
448 file correctly even on Windows.
449
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000450- logging's atexit hook now runs even if the rest of the module has
451 already been cleaned up.
452
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000453- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000454
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000455- Bug #1531405, format_exception no longer raises an exception if
456 str(exception) raised an exception.
457
Neil Schemenauer06ded092006-08-04 16:20:30 +0000458- Fix a bug in the ``compiler`` package that caused invalid code to be
459 generated for nested functions.

468 raises the correct exceptions.
469
Thomas Heller1ce433e2006-08-14 16:20:04 +0000470- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
471 '-no-stack-protector' compiler flag for OpenBSD has been removed.
472
Thomas Heller86720042006-08-14 11:17:48 +0000473- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
474 uses the _as_parameter_ attribute when objects are passed to foreign
475 function calls. The ctypes version number was changed to 1.0.1.
476
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000477- Bug #1530559, struct.pack raises TypeError where it used to convert.
478 Passing float arguments to struct.pack when integers are expected
479 now triggers a DeprecationWarning.

529Core and builtins
530-----------------
531
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000532- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000533 returned a long (see PEP 353).
534
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000535- Bug #1515471: string.replace() accepts character buffers again.
536
Neal Norwitz07aadb12006-07-30 06:55:48 +0000537- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
538 This provides the proper warning for struct.pack().
539 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
540
Neal Norwitz0d62a062006-07-30 06:53:31 +0000541- Patch #1531113: Fix augmented assignment with yield expressions.
542 Also fix a SystemError when trying to assign to yield expressions.
543
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000544- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
545 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
546 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
547 excessive filesystem operations during imports.
548
Tim Petersbc24eee2006-07-27 01:14:53 +0000549- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
550 operations on signed longs that are formally undefined by C.
551 Unfortunately, at least one compiler now cares about that, so complicated
552 the code to make that compiler happy again.
553
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000554- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
555
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000556- Patch #1232023: Stop including current directory in search
557 path on Windows.
558
Neal Norwitze1fdb322006-07-21 05:32:28 +0000559- Fix some potential crashes found with failmalloc.
560
Neal Norwitze7563102006-07-17 01:00:16 +0000561- Fix warnings reported by Klocwork's static analysis tool.
562
Neal Norwitz84be93b2006-07-16 01:50:38 +0000563- Bug #1512814, Fix incorrect lineno's when code within a function
564 had more than 255 blank lines.
565
Georg Brandl9dceedb2006-07-12 15:31:17 +0000566- Patch #1521179: Python now accepts the standard options ``--help`` and
567 ``--version`` as well as ``/?`` on Windows.
568
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000569- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000570 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000571 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000572
Tim Peters112aad32006-07-19 00:03:19 +0000573- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000574 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000575 new ``sys._current_frames()`` returns a dictionary with one entry,
576 mapping the faux "thread id" 0 to the current frame.
577
Ronald Oussoren3075e162006-07-25 20:28:55 +0000578- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

583
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000584- Correction of patch #1455898: In the mbcs decoder, set final=False
585 for stream decoder, but final=True for the decode function.
586
Georg Brandl07fec3a2006-08-01 18:49:24 +0000587- os.urandom no longer masks unrelated exceptions like SystemExit or
588 KeyboardInterrupt.
589
Tim Peters4643c2f2006-08-10 22:45:34 +0000590- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000591 shutil.copytree on Windows
592
Georg Brandle34ac7c2006-07-30 11:07:23 +0000593- Bug #1002398: The documentation for os.path.sameopenfile now correctly
594 refers to file descriptors, not file objects.
595
Tim Petersc10c9d02006-09-05 02:18:09 +0000596- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000597 to make it appear at both names, has been removed. Bug #1511497,

Tim Peters6f681472006-07-27 23:44:37 +0000603- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
604 lost that tests are sorted by name before being run. This rarely
605 matters for well-written tests, but can create baffling symptoms if
606 side effects from one test to the next affect outcomes. ``DocTestFinder``
607 has been changed to sort the list of tests it returns.
608
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000609- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000610 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000611
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000612- Bug #978833: Really close underlying socket in _socketobject.close.
613
Georg Brandl8c036cc2006-08-20 13:15:39 +0000614- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
615 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000616
Georg Brandlcf0c1722006-07-26 07:23:32 +0000617- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
618 to recursive calls and call it with the failing package name.
619
Martin v. Löwis0b483032006-07-25 09:53:12 +0000620- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
621
Georg Brandlc13c34c2006-07-24 14:09:56 +0000622- Patch #1515343: Fix printing of deprecated string exceptions with a
623 value in the traceback module.
624
Greg Ward48fae7a2006-07-23 16:05:51 +0000625- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
626
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000627- Patch #1524429: Use repr() instead of backticks in Tkinter again.
628
Brett Cannoncaebe222006-07-18 04:41:36 +0000629- Bug #1520914: Change time.strftime() to accept a zero for any position in its
630 argument tuple. For arguments where zero is illegal, the value is forced to
631 the minimum value that is correct. This is to support an undocumented but
632 common way people used to fill in inconsequential information in the time
633 tuple pre-2.4.
634
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000635- Patch #1220874: Update the binhex module for Mach-O.
636
Barry Warsawb110bad2006-07-21 14:51:07 +0000637- The email package has improved RFC 2231 support, specifically for
638 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
639 (name*0=<blah>) parameter continuations. This may change the types of
640 values returned from email.message.Message.get_param() and friends.
641 Specifically in some cases where non-encoded continuations were used,
642 get_param() used to return a 3-tuple of (None, None, string) whereas now it
643 will just return the string (since non-encoded continuations don't have
644 charset and language parts).
645
646 Also, whereas % values were decoded in all parameter continuations, they are
647 now only decoded in encoded parameter parts.
648
Ronald Oussoren3075e162006-07-25 20:28:55 +0000649- Bug #1517990: IDLE keybindings on MacOS X now work correctly
650
651- Bug #1517996: IDLE now longer shows the default Tk menu when a
652 path browser, class browser or debugger is the frontmost window on MacOS X
653
Barry Warsaw00decd72006-07-27 23:43:15 +0000654- Patch #1520294: Support for getset and member descriptors in types.py,
655 inspect.py, and pydoc.py. Specifically, this allows for querying the type
656 of an object against these built-in types and more importantly, for getting
657 their docstrings printed in the interactive interpreter's help() function.

662
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000663- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
664 a socket operation on a socket with a timeout, the exception will be
665 caught correctly. Previously, the exception was not caught.
666
Thomas Heller1393d6a2006-07-28 21:43:20 +0000667- Patch #1529514: The _ctypes extension is now compiled on more
668 openbsd target platforms.
669
Tim Peters9cab5932006-07-28 00:30:00 +0000670- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
671 a memory leak, affecting pickles and deep copies.
672
Tim Petersbc24eee2006-07-27 01:14:53 +0000673- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

677
Thomas Hellerce049a02006-07-14 17:51:14 +0000678- Patch #1521817: Index range checking on ctypes arrays containing
679 exactly one element enabled again. This allows iterating over these
680 arrays, without the need to check the array size before.
681
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000682- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000683 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000684 /dev/null in certain cases; this is now fixed.
685
Thomas Heller47d7a062006-07-12 08:43:47 +0000686- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
687 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000688
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000689- Because of a misspelled preprocessor symbol, ctypes was always
690 compiled without thread support; this is now fixed.
691
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000692- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
693 methods now allow their database parameter to be None as the
694 sleepycat API allows.
695
Matt Flemingec926502006-07-28 11:27:27 +0000696- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
697 bluetooth API compared with Linux and FreeBSD.
698
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000699Tests
700-----
701
702- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
703 how long the test file should take to play. Now accepts taking 2.93 secs
704 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
705
Georg Brandl4793aa32006-07-28 18:31:39 +0000706- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
707 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
708 run via ``regrtest.py``. Now they do.

717
718- PythonLauncher now works correctly when the path to the script contains
719 characters that are treated specially by the shell (such as quotes).
720
721- Bug #1527397: PythonLauncher now launches scripts with the working directory
722 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000723 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000724 expect.

733-----------------
734
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000735- Bug #1441486: The literal representation of -(sys.maxint - 1)
736 again evaluates to a int object, not a long.
737
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000738- Bug #1501934: The scope of global variables that are locally assigned
739 using augmented assignment is now correctly determined.
740
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000741- Bug #927248: Recursive method-wrapper objects can now safely
742 be released.
743
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000744- Bug #1417699: Reject locale-specific decimal point in float()
745 and atof().
746
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000747- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
748 omit a default "error" argument for NULL pointer. This allows
749 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000750
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000751- Bug #1519018: 'as' is now validated properly in import statements.
752
Neal Norwitz28746ab2006-07-09 22:14:42 +0000753- On 64 bit systems, int literals that use less than 64 bits are
754 now ints rather than longs.
755
Neal Norwitzed657552006-07-10 00:04:44 +0000756- Bug #1512814, Fix incorrect lineno's when code at module scope
757 started after line 256.
758
Tim Peters32a83612006-07-10 21:08:24 +0000759- New function ``sys._current_frames()`` returns a dict mapping thread
760 id to topmost thread stack frame. This is for expert use, and is
761 especially useful for debugging application deadlocks. The functionality
762 was previously available in Fazal Majid's ``threadframe`` extension
763 module, but it wasn't possible to do this in a wholly threadsafe way from
764 an extension.

781
Thomas Woutersadd19112006-07-05 11:03:49 +0000782- string.Template() now correctly handles tuple-values. Previously,

784 be treated as the value they contain, instead.
785
Martin v. Löwisede77f52006-07-03 13:01:35 +0000786- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Georg Brandl1be63af2006-06-28 20:23:25 +0000810- Fix a bug in the turtle module's end_fill function.
811
Brett Cannon53ab5b72006-06-22 16:49:14 +0000812- Bug #1510580: The 'warnings' module improperly required that a Warning
813 category be either a types.ClassType and a subclass of Warning. The proper
814 check is just that it is a subclass with Warning as the documentation states.
815
Georg Brandlad29e632006-06-21 17:45:17 +0000816- The compiler module now correctly compiles the new try-except-finally
817 statement (bug #1509132).
818
Neal Norwitz60373cd2006-06-22 06:30:50 +0000819- The wsgiref package is now installed properly on Unix.
820
Vinay Sajip28e57612006-07-01 10:45:20 +0000821- A bug was fixed in logging.config.fileConfig() which caused a crash on
822 shutdown when fileConfig() was called multiple times.
823
Gerhard Häring762fbd32006-07-02 17:48:30 +0000824- The sqlite3 module did cut off data from the SQLite database at the first
825 null character before sending it to a custom converter. This has been fixed
826 now.

Tim Peters112aad32006-07-19 00:03:19 +0000831- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
832 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
833 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000834
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000835- Assigning None to pointer type fields in ctypes structures possible
836 overwrote the wrong fields, this is fixed now.
837
838- Fixed a segfault in _ctypes when ctypes.wintypes were imported
839 on non-Windows platforms.
840
841- Bug #1518190: The ctypes.c_void_p constructor now accepts any
842 integer or long, without range checking.
843
844- Patch #1517790: It is now possible to use custom objects in the ctypes
845 foreign function argtypes sequence as long as they provide a from_param
846 method, no longer is it required that the object is a ctypes type.
847
848- The '_ctypes' extension module now works when Python is configured
849 with the --without-threads option.

866
Tim Peters32a83612006-07-10 21:08:24 +0000867- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000868 Previously, the slight difference could cause compilation errors of the
869 'zlib' module on systems with more than one version of zlib.
870
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000871- The MSI compileall step was fixed to also support a TARGETDIR

Brett Cannonea3912b2006-06-13 21:46:41 +0000909- Bug #992017: A classic class that defined a __coerce__() method that returned
910 its arguments swapped would infinitely recurse and segfault the interpreter.
911
Neal Norwitz909eb122006-06-12 02:13:21 +0000912- Fix the socket tests so they can be run concurrently.
913
Neal Norwitzb9845e72006-06-12 02:11:18 +0000914- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000915 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000916
Brett Cannon22565aa2006-06-09 22:31:23 +0000917- Bug #532646: object.__call__() will continue looking for the __call__
918 attribute on objects until one without one is found. This leads to recursion
919 when you take a class and set its __call__ attribute to an instance of the
920 class. Originally fixed for classic classes, but this fix is for new-style.
921 Removes the infinite_rec_3 crasher.
922
Georg Brandl24250812006-06-09 18:45:48 +0000923- The string and unicode methods startswith() and endswith() now accept
924 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
925
Brett Cannonde3b0522006-06-08 17:00:45 +0000926- Buffer objects, at the C level, never used the char buffer
927 implementation even when the char buffer for the wrapped object was
928 explicitly requested (originally returned the read or write buffer).
929 Now a TypeError is raised if the char buffer is not present but is
930 requested.
931
Georg Brandlddbaa662006-06-04 21:56:52 +0000932- Patch #1346214: Statements like "if 0: suite" are now again optimized
933 away like they were in Python 2.4.
934
Georg Brandlb7c8f542006-05-27 12:30:25 +0000935- Builtin exceptions are now full-blown new-style classes instead of
936 instances pretending to be classes, which speeds up exception handling
937 by about 80% in comparison to 2.5a2.
938
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000939- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
940 Unicode 4.1.
941
Georg Brandlf4ef1162006-05-26 18:03:31 +0000942- Patch #921466: sys.path_importer_cache is now used to cache valid and
943 invalid file paths for the built-in import machinery which leads to
944 fewer open calls on startup.
945
Tim Peters696cf432006-05-24 21:10:40 +0000946- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
947 of-2 bases. The largest speedup is for inputs with about 1000 decimal
948 digits. Conversion from non-power-of-2 bases remains quadratic-time in
949 the number of input digits (it was and remains linear-time for bases
950 2, 4, 8, 16 and 32).
951
Tim Petersb713ec22006-05-23 18:45:30 +0000952- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
953 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
954 an integer close to ``sys.maxint``. This was repaired by patch
955 #1335972, which also gives a nice speedup.
956
Richard Jonescebbefc2006-05-23 18:28:17 +0000957- Patch #1337051: reduced size of frame objects.
958
959- PyErr_NewException now accepts a tuple of base classes as its
960 "base" parameter.
961
Richard Jones7c88dcc2006-05-23 10:37:38 +0000962- Patch #876206: function call speedup by retaining allocated frame
963 objects.
964
Georg Brandl7b90e162006-05-18 07:01:27 +0000965- Bug #1462152: file() now checks more thoroughly for invalid mode
966 strings and removes a possible "U" before passing the mode to the
967 C library function.
968
Neal Norwitz1004a532006-05-15 07:17:23 +0000969- Patch #1488312, Fix memory alignment problem on SPARC in unicode
970
Neal Norwitz373f0a72006-05-15 07:04:36 +0000971- Bug #1487966: Fix SystemError with conditional expression in assignment
972
Martin v. Löwis879768d2006-05-11 13:28:43 +0000973- WindowsError now has two error code attributes: errno, which carries
974 the error values from errno.h, and winerror, which carries the error
975 values from winerror.h. Previous versions put the winerror.h values
976 (from GetLastError()) into the errno attribute.
977
Martin v. Löwis77736712006-05-04 05:51:03 +0000978- Patch #1475845: Raise IndentationError for unexpected indent.
979
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000980- Patch #1479181: split open() and file() from being aliases for each other.
981
Tim Peters44bd9862006-06-01 13:49:23 +0000982- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
983 methods were always silently ignored by dictionaries when comparing keys.
984 They are now passed through (except when using the C API function
985 ``PyDict_GetItem()``, whose semantics did not change).
986
987- Bug #1456209: In some obscure cases it was possible for a class with a
988 custom ``__eq__()`` method to confuse dict internals when class instances
989 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
990 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000995- Bug #1295808: expat symbols should be namespaced in pyexpat
996
997- Patch #1462338: Upgrade pyexpat to expat 2.0.0
998
Brett Cannon6ee7d012006-06-08 16:23:04 +0000999- Change binascii.hexlify to accept a read-only buffer instead of only a char
1000 buffer and actually follow its documentation.
1001
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001002- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1003
Nick Coghlanc649ec52006-05-29 12:43:05 +00001004- Patch #1478788 (modified version): The functional extension module has
1005 been renamed to _functools and a functools Python wrapper module added.
1006 This provides a home for additional function related utilities that are
1007 not specifically about functional programming. See PEP 309.
1008
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001009- Patch #1493701: performance enhancements for struct module.
1010
Georg Brandl378d5922006-05-17 14:26:50 +00001011- Patch #1490224: time.altzone is now set correctly on Cygwin.
1012
Georg Brandl8d3342b2006-05-16 07:38:27 +00001013- Patch #1435422: zlib's compress and decompress objects now have a
1014 copy() method.
1015
Andrew MacIntyre92913322006-06-13 15:04:24 +00001016- Patch #1454481: thread stack size is now tunable at runtime for thread
1017 enabled builds on Windows and systems with Posix threads support.
1018
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001019- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1020 (up to the system limit of 32K characters).
1021
1022- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1023 As a result, these functions now raise WindowsError instead of OSError.
1024
Tim Peters7a822da2006-05-25 21:50:17 +00001025- ``time.clock()`` on Win64 should use the high-performance Windows
1026 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1027 Windows platforms).
1028
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001029- Calling Tk_Init twice is refused if the first call failed as that
1030 may deadlock.
1031
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001032- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1033 accept it without potentially using an uninitialized pointer.
1034
1035- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1036 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1037 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001038
Gregory P. Smith372b5832006-06-05 18:48:21 +00001039- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001040 [pybsddb project SF patch number 1466734]
1041
Gregory P. Smith372b5832006-06-05 18:48:21 +00001042- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1043 parameter is supplied. [SF pybsddb bug #1477863]
1044
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001045- bsddb: the __len__ method of a DB object has been fixed to return correct
1046 results. It could previously incorrectly return 0 in some cases.
1047 Fixes SF bug 1493322 (pybsddb bug 1184012).
1048
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001049- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1050 aborts the db transaction safely when a modifier callback fails.
1051 Fixes SF python patch/bug #1408584.
1052
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001053- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001054 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001055 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1056 database calls that would previously deadlock. [SF python bug #775414]
1057
Vinay Sajip28e57612006-07-01 10:45:20 +00001058- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1067 functions.
1068
Martin v. Löwis3798da02006-06-17 18:44:27 +00001069- Patch #812986: Update turtle output even if not tracing.

1073
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001074- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1075
Martin v. Löwis337487e2006-06-17 09:15:14 +00001076- Patch #763580: Add name and value arguments to Tkinter variable
1077 classes.
1078
Georg Brandl83cc0d02006-06-14 08:50:03 +00001079- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1080 mime.types file for determining MIME types.
1081
Georg Brandl2605ca82006-06-14 06:08:31 +00001082- Bug #1339007: Shelf objects now don't raise an exception in their
1083 __del__ method when initialization failed.
1084
Martin v. Löwisd8251432006-06-14 05:21:04 +00001085- Patch #1455898: The MBCS codec now supports the incremental mode for
1086 double-byte encodings.
1087
Tim Peters43898b42006-06-14 04:09:25 +00001088- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1089 guarantee that adjacent triples in the return list always describe
1090 non-adjacent blocks. Previously, a pair of matching blocks could end
1091 up being described by multiple adjacent triples that formed a partition
1092 of the matching pair.
1093
Greg Ward0e0c9f42006-06-11 16:24:11 +00001094- Bug #1498146: fix optparse to handle Unicode strings in option help,
1095 description, and epilog.
1096
Greg Wardd1c797e2006-06-11 14:42:41 +00001097- Bug #1366250: minor optparse documentation error.
1098
Greg Ward7f547402006-06-11 00:40:49 +00001099- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1100 clarify docs.
1101
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001102- The wsgiref package has been added to the standard library.
1103
Nick Coghlan676725d2006-06-08 13:54:49 +00001104- The functions update_wrapper() and wraps() have been added to the functools
1105 module. These make it easier to copy relevant metadata from the original
1106 function when writing wrapper functions.
1107
Tim Petersd6a9eef2006-06-05 01:48:21 +00001108- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1109 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001110
Martin v. Löwis3f767792006-06-04 19:36:28 +00001111- Patch #1359618: Speed up charmap encoder by using a trie structure
1112 for lookup.
1113
Tim Petersd609b1a2006-06-02 23:22:51 +00001114- The functions in the ``pprint`` module now sort dictionaries by key
1115 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1116 if and only if its display required more than one line, although that
1117 wasn't documented. The new behavior increases predictability; e.g.,
1118 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1119
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001120- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1121 (thanks for J. J. Lee).
1122
Georg Brandl2b330372006-05-28 20:23:12 +00001123- Patch #1496206: improve urllib2 handling of passwords with respect to
1124 default HTTP and HTTPS ports.
1125
George Yoshidaf3c65de2006-05-28 16:39:09 +00001126- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1127
Bob Ippolito7298f272006-05-23 18:43:47 +00001128- Patch #1281707: speed up gzip.readline.
1129
Georg Brandlb89316f2006-05-17 15:51:16 +00001130- Patch #1180296: Two new functions were added to the locale module:
1131 format_string() to get the effect of "format % items" but locale-aware,
1132 and currency() to format a monetary number with currency sign.
1133
Georg Brandle3a25832006-05-17 14:56:04 +00001134- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1135 and several features added, such as speed and geometry control.
1136
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001137- Patch #1488881: add support for external file objects in bz2 compressed
1138 tarfiles.
1139
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001140- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1141 stdout arguments, making it possible to redirect input and output
1142 for remote debugging.
1143
1144- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1145 a couple of issues, notably handling of long file names using the
1146 GNU LONGNAME extension.
1147
1148- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1149 new flag when ``name`` is already the name of an option flag.
1150
1151- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1152 package.
1153
1154- Patch #1472854: make the rlcompleter.Completer class usable on non-
1155 UNIX platforms.
1156
1157- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001190What's New in Python 2.5 alpha 2?
1191=================================
1192
1193*Release date: 27-APR-2006*
1194
1195Core and builtins
1196-----------------
1197
Thomas Heller1b046642006-04-18 18:51:06 +00001198- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1199 by converting these apis from macros into exported functions again:
1200
1201 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1202 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1203 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1204 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1205 PyRun_String Py_CompileString
1206
Martin v. Löwis45294a92006-04-18 06:24:08 +00001207- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1208
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001209- All uses of PyStructSequence_InitType have been changed to initialize
1210 the type objects only once, even if the interpreter is initialized
1211 multiple times.
1212
Neal Norwitz61546162006-04-14 05:20:28 +00001213- Bug #1454485, array.array('u') could crash the interpreter. This was
1214 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1215 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1216
1217- Py_UNICODE is unsigned. It was always documented as unsigned, but
1218 due to a bug had a signed value in previous versions.

Tim Peters3a5e8b12006-04-11 01:44:07 +00001220- Patch #837242: ``id()`` of any Python object always gives a positive
1221 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1222 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001223 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001224 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001225
Tim Peters3a5e8b12006-04-11 01:44:07 +00001226 def __hash__(self):
1227 return id(self) # WRONG
1228
1229 because a hash result must be a (short) Python int but it was always
1230 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001231 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001232 was always usable as a hash value before this patch. That's no longer
1233 necessarily so.
1234
1235- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001236 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001237 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001238 #1454844)
1239
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001240- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1241 involving generators that have paused outside of any ``try`` or ``with``
1242 blocks. (In 2.5a1, a paused generator that was part of a reference
1243 cycle could not be garbage collected, regardless of whether it was
1244 paused in a ``try`` or ``with`` block.)

1251
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001252- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1253 fails with an error condition.
1254
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001255- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1256
1257- Bug #1117761: bsddb.*open() no longer raises an exception when using
1258 the cachesize parameter.
1259
1260- Bug #1149413: bsddb.*open() no longer raises an exception when using
1261 a temporary db (file=None) with the 'n' flag to truncate on open.
1262
1263- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1264 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001265
Armin Rigoa9017c32006-04-19 11:50:27 +00001266- Patch #1062014: AF_UNIX sockets under Linux have a special
1267 abstract namespace that is now fully supported.
1268

1270-------
1271
Peter Astrand7d1d4362006-07-14 14:04:45 +00001272- Bug #1223937: subprocess.CalledProcessError reports the exit status
1273 of the process using the returncode attribute, instead of
1274 abusing errno.
1275
Tim Peters711bf302006-04-25 03:31:36 +00001276- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1277 a doctest to be skipped (the code is not run, and the expected output
1278 or exception is ignored).
1279
Nick Coghlanda2268f2006-04-24 04:37:15 +00001280- Fixed contextlib.nested to cope with exceptions being raised and
1281 caught inside exit handlers.
1282
Greg Wardab05edc2006-04-23 03:47:58 +00001283- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1284 hex, octal, or binary; add ``append_const`` action; keep going if
1285 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1286 added ``epilog`` for better help generation).
1287
Tim Peters21fbd572006-04-21 21:18:10 +00001288- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1289 called from a thread spawned as a side effect of importing a module.
1290
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001291- The pydoc module now supports documenting packages contained in
1292 .zip or .egg files.
1293
1294- The pkgutil module now has several new utility functions, such
1295 as ``walk_packages()`` to support working with packages that are either
1296 in the filesystem or zip files.
1297
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001298- The mailbox module can now modify and delete messages from
1299 mailboxes, in addition to simply reading them. Thanks to Gregory
1300 K. Johnson for writing the code, and to the 2005 Google Summer of
1301 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001302
Tim Petersc7605f22006-04-17 21:12:33 +00001303- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001312- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1313 Windows. Bug #1469163.
1314
Phillip J. Eby47032112006-04-11 01:07:43 +00001315- The warnings, linecache, inspect, traceback, site, and doctest modules
1316 were updated to work correctly with modules imported from zipfiles or
1317 via other PEP 302 __loader__ objects.

1325
Skip Montanaro262fb922006-04-21 02:31:07 +00001326- The pstats.Stats class accepts an optional stream keyword argument to
1327 direct output to an alternate file-like object.
1328
Anthony Baxter51bcb682006-04-05 14:51:42 +00001329Build
1330-----
1331
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001332- The Makefile now has a reindent target, which runs reindent.py on
1333 the library.
1334
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001335- Patch #1470875: Building Python with MS Free Compiler
1336
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001337- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001338
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001339- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1340 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001341 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001342 CXX from --with-cxx-main, see description in README.
1343
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001344- Patch #1429775: Link extension modules with the shared libpython.
1345
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001346- Fixed a libffi build problem on MIPS systems.
1347
Tim Peters8931ff12006-05-13 23:28:20 +00001348- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1349 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1350 and "%zu" for unsigned integers of type ``size_t``.
1351
Anthony Baxter51bcb682006-04-05 14:51:42 +00001352Tests
1353-----
1354
Nick Coghlanda2268f2006-04-24 04:37:15 +00001355- test_contextlib now checks contextlib.nested can cope with exceptions
1356 being raised and caught inside exit handlers.
1357
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001358- test_cmd_line now checks operation of the -m and -c command switches
1359
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001360- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1361 it separately and by hand. It also wasn't cleaning up its changes to
1362 the current Decimal context.
1363
Thomas Woutersabd08882006-04-26 15:53:30 +00001364- regrtest.py now has a -M option to run tests that test the new limits of
1365 containers, on 64-bit architectures. Running these tests is only sensible
1366 on 64-bit machines with more than two gigabytes of memory. The argument
1367 passed is the maximum amount of memory for the tests to use.

1376-------------
1377
Tim Petersb06d28c2006-05-12 01:57:59 +00001378- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1379
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001380- PEP 343: Added Context Types section to the library reference
1381 and attempted to bring other PEP 343 related documentation into
1382 line with the implementation and/or python-dev discussions.
1383
Tim Peters8dc73d22006-04-24 02:03:16 +00001384- Bug #1337990: clarified that ``doctest`` does not support examples
1385 requiring both expected output and an exception.

1389=================================
1390
Anthony Baxterebed3f62006-04-03 15:03:44 +00001391*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001392
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001393Core and builtins
1394-----------------
1395
Nick Coghlan43832302006-04-23 17:04:07 +00001396- PEP 338: -m command line switch now delegates to runpy.run_module
1397 allowing it to support modules in packages and zipfiles
1398
Martin v. Löwisc661b882006-04-20 04:54:23 +00001399- On Windows, .DLL is not an accepted file name extension for
1400 extension modules anymore; extensions are only found if they
1401 end in .PYD.
1402
Martin v. Löwisea62d252006-04-03 10:56:49 +00001403- Bug #1421664: sys.stderr.encoding is now set to the same value as
1404 sys.stdout.encoding.
1405
Neal Norwitz92e212f2006-04-03 04:48:37 +00001406- __import__ accepts keyword arguments.
1407
Georg Brandlccadf842006-03-31 18:54:53 +00001408- Patch #1460496: round() now accepts keyword arguments.
1409
Anthony Baxter262c00a2006-03-30 10:53:17 +00001410- Fixed bug #1459029 - unicode reprs were double-escaped.
1411
Hye-Shik Changd478f342006-03-23 12:32:36 +00001412- Patch #1396919: The system scope threads are reenabled on FreeBSD
1413 5.4 and later versions.
1414
Neal Norwitze98ccf62006-03-23 05:39:47 +00001415- Bug #1115379: Compiling a Unicode string with an encoding declaration
1416 now gives a SyntaxError.
1417
Georg Brandlabd1ff82006-03-18 07:59:59 +00001418- Previously, Python code had no easy way to access the contents of a
1419 cell object. Now, a ``cell_contents`` attribute has been added
1420 (closes patch #1170323).
1421
Tim Peterscf79aac2006-03-16 01:14:46 +00001422- Patch #1123430: Python's small-object allocator now returns an arena to
1423 the system ``free()`` when all memory within an arena becomes unused
1424 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1425 freed. Some applications will see a drop in virtual memory size now,
1426 especially long-running applications that, from time to time, temporarily
1427 use a large number of small objects. Note that when Python returns an
1428 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001429 platform C library will in turn return that memory to the operating system.
1430 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001431 appears to be effective at least on Microsoft C and gcc-based systems.
1432 Thanks to Evan Jones for hard work and patience.
1433
Georg Brandl533ff6f2006-03-08 18:09:27 +00001434- Patch #1434038: property() now uses the getter's docstring if there is
1435 no "doc" argument given. This makes it possible to legitimately use
1436 property() as a decorator to produce a read-only property.
1437
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001438- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1439 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1440 of requiring an int or long in slicing and a few other contexts, enabling
1441 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1442
Neal Norwitz995acdf2006-03-07 05:01:00 +00001443- Fixed various bugs reported by Coverity's Prevent tool.
1444
Brett Cannonbf364092006-03-01 04:25:17 +00001445- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1446 new exception base class, BaseException, which has a new message attribute.
1447 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1448 Raising a string exception now raises a DeprecationWarning.
1449
Thomas Woutersfb609f42006-02-28 16:37:25 +00001450- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1451 explicitly relative, using 'from .module import name' to mean 'from the same
1452 package as this module is in. Imports without dots still default to the
1453 old relative-then-absolute, unless 'from __future__ import
1454 absolute_import' is used.
1455
Brett Cannona7446e32006-02-27 23:39:10 +00001456- Properly check if 'warnings' raises an exception (usually when a filter set
1457 to "error" is triggered) when raising a warning for raising string
1458 exceptions.
1459
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001460- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001461 The name was removed from Include/code.h.
1462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001463- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001464
Guido van Rossum1968ad32006-02-25 22:38:04 +00001465- Patch 1433928:
1466 - The copy module now "copies" function objects (as atomic objects).
1467 - dict.__getitem__ now looks for a __missing__ hook before raising
1468 KeyError.
1469
Tim Peters84ef21c2006-02-28 20:39:06 +00001470- PEP 343: with statement implemented. Needs ``from __future__ import
1471 with_statement``. Use of 'with' as a variable will generate a warning.
1472 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001473 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001474 The following objects have __context__ methods:
1475 - The built-in file type.
1476 - The thread.LockType type.
1477 - The following types defined by the threading module:
1478 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1479 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001480
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001481- Fix the encodings package codec search function to only search
1482 inside its own package. Fixes problem reported in patch #1433198.
1483
1484 Note: Codec packages should implement and register their own
1485 codec search function. PEP 100 has the details.
1486
Tim Peters9ea89d22006-06-04 03:26:02 +00001487- PEP 353: Using ``Py_ssize_t`` as the index type.
1488
1489- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1490 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1491 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1492 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1493 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001494
Neal Norwitzfc76d632006-01-10 06:03:13 +00001495- Patch #1400181, fix unicode string formatting to not use the locale.
1496 This is how string objects work. u'%f' could use , instead of .
1497 for the decimal point. Now both strings and unicode always use periods.
1498
Neal Norwitz671b9e32006-01-09 07:07:12 +00001499- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1500 configure would break checking curses.h.
1501
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001502- Bug #959576: The pwd module is now builtin. This allows Python to be
1503 built on UNIX platforms without $HOME set.
1504
Neal Norwitzc10978f2005-12-19 06:07:16 +00001505- Bug #1072182, fix some potential problems if characters are signed.
1506
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001507- Bug #889500, fix line number on SyntaxWarning for global declarations.
1508
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001509- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1510
Neal Norwitze7214a12005-12-18 05:03:17 +00001511- Support for converting hex strings to floats no longer works.
1512 This was not portable. float('0x3') now raises a ValueError.
1513
Barry Warsaw2a38a862005-12-18 01:27:35 +00001514- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001515 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001516 is now displayed in interactive prompt banner.
1517
Georg Brandlfa166682005-12-17 21:45:17 +00001518- Implementation of PEP 341 - Unification of try/except and try/finally.
1519 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001520 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001521
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001522- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1523 now encodes backslash correctly.
1524
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001525- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1526
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001527- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001528 and long longs.
1529
Neal Norwitz67715f02005-11-09 06:59:35 +00001530- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001531 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001532 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001533
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001534- Replaced most Unicode charmap codecs with new ones using the
1535 new Unicode translate string feature in the builtin charmap
1536 codec; the codecs were created from the mapping tables available
1537 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1538 encodings now include a mapping for the Apple logo)
1539
Tim Peterse3547fd2005-12-16 23:13:57 +00001540- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001541
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001542- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001543
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001544- A new AST parser implementation was completed. The abstract
1545 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001546 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001548- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001549 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1550
Neal Norwitz708e51a2005-10-03 04:48:15 +00001551- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1552
Neal Norwitz11bd1192005-10-03 00:54:56 +00001553- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1554 Provide a warning when a directory is passed on the command line.
1555
Neal Norwitz40d37812005-10-02 01:48:49 +00001556- Fix segfault with invalid coding.
1557
1558- SF bug #772896: unknown encoding results in MemoryError.
1559
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001560- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001561 supported a __len__() method which evaluated to False when the iterator
1562 was empty.
1563
Guido van Rossum630db602005-09-20 18:49:54 +00001564- On 64-bit platforms, when __len__() returns a value that cannot be
1565 represented as a C int, raise OverflowError.
1566
Skip Montanarof8948ca2005-09-19 03:54:46 +00001567- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001568 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001569
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001570- SF bug #893549: parsing keyword arguments was broken with a few format
1571 codes.
1572
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001573- Changes donated by Elemental Security to make it work on AIX 5.3
1574 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1575 bug #105470: test_pwd fails on 64bit system (Opteron).
1576
Guido van Rossum539c6622005-09-14 17:49:54 +00001577- Changes donated by Elemental Security to make it work on HP-UX 11 on
1578 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1579
Georg Brandl4550b8d2005-08-26 06:43:52 +00001580- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001581 (fixes bug #1119418).
1582
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001583- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1584
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001585- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1586 exceptions that cause a function to exit.
1587
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001588- The implementation of set() and frozenset() was revised to use its
1589 own internal data structure. Memory consumption is reduced by 1/3
1590 and there are modest speed-ups as well. The API is unchanged.
1591
Tim Petersde7990b2005-07-17 23:45:23 +00001592- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1593
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001594- SF bug #1229429: PyObject_CallMethod failed to decrement some
1595 reference counts in some error exit cases.
1596
Tim Petersecc6e6a2005-07-10 22:30:55 +00001597- SF bug #1185883: Python's small-object memory allocator took over
1598 a block managed by the platform C library whenever a realloc specified
1599 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001600 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001601 portable way to copy data from the C-managed block into Python's
1602 small-object space without risking a memory fault. Python's small-object
1603 realloc now leaves such blocks under the control of the platform C
1604 realloc.
1605
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001606- SF bug #1232517: An overflow error was not detected properly when
1607 attempting to convert a large float to an int in os.utime().
1608
Raymond Hettinger3296e692005-06-29 23:29:56 +00001609- SF bug #1224347: hex longs now print with lowercase letters just
1610 like their int counterparts.
1611
Michael W. Hudson188d4362005-06-20 16:52:57 +00001612- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1613 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1614 interpreter states; back out that fix and do a better job (see
1615 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1616 for a longer write-up of the problem).
1617
Michael W. Hudsondf888462005-06-03 14:41:55 +00001618- SF patch #1180995: marshal now uses a binary format by default when
1619 serializing floats.
1620
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001621- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1622 the routines that promise to produce IEEE 754 binary representations
1623 of floats now simply copy bytes around.
1624
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001625- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1626 278.
1627
Brett Cannonc3647ac2005-04-26 03:45:26 +00001628- patch #1109424: int, long, float, complex, and unicode now check for the
1629 proper magic slot for type conversions when subclassed. Previously the
1630 magic slot was ignored during conversion. Semantics now match the way
1631 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001632 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001633 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001634 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001635
Barry Warsawc8d907c2005-04-19 23:43:40 +00001636- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1637 NULL, now raise an AttributeError when attempting to set or delete the
1638 attribute. Previously a TypeError was raised, but this was inconsistent
1639 with the equivalent pure-Python implementation.
1640
Michael W. Hudson774479c2005-04-18 08:46:17 +00001641- It is now safe to call PyGILState_Release() before
1642 PyEval_InitThreads() (note that if there is reason to believe there
1643 are multiple threads around you still must call PyEval_InitThreads()
1644 before using the Python API; this fix is for extension modules that
1645 have no way of knowing if Python is multi-threaded yet).
1646
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001647- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1648 disabled caused a crash.
1649
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001650- Bug #1165306: instancemethod_new allowed the creation of a method
1651 with im_class == im_self == NULL, which caused a crash when called.
1652
Tim Petersecc6e6a2005-07-10 22:30:55 +00001653- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001654 fixes the crash seen in bug #1165761
1655
Raymond Hettinger96229b12005-03-11 06:49:40 +00001656- Added two new builtins, any() and all().
1657
Brett Cannon409d8f22005-03-05 06:47:57 +00001658- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001659 (e.g., ``class C(): pass`` is no longer a syntax error).
1660 Patch #1176012 added support to the 'parser' module and 'compiler' package
1661 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001662
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001663- Patch #1115086: Support PY_LONGLONG in structmember.
1664
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001665- Bug #1155938: new style classes did not check that __init__() was
1666 returning None.
1667
Tim Petersecc6e6a2005-07-10 22:30:55 +00001668- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001669 ('\') with a specific error message.
1670
Martin v. Löwisff232d72005-03-03 09:24:38 +00001671- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1672
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001673- Bug #1124295: the __name__ attribute of file objects was
1674 inadvertently made inaccessible in restricted mode.
1675
Tim Petersecc6e6a2005-07-10 22:30:55 +00001676- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001677 an ferror() call.
1678
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001679- min() and max() now support key= arguments with the same meaning as in
1680 list.sort().
1681
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001682- The peephole optimizer now performs simple constant folding in expressions:
1683 (2+3) --> (5).
1684
Raymond Hettingera422c342005-01-11 03:03:27 +00001685- set and frozenset objects can now be marshalled. SF #1098985.
1686
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001687- Bug #1077106: Poor argument checking could cause memory corruption
1688 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001689
Jeremy Hyltonab630502005-02-04 18:44:06 +00001690- The parser did not complain about future statements in illegal
1691 positions. It once again reports a syntax error if a future
1692 statement occurs after anything other than a doc string.
1693
Neil Schemenauercf52c072005-08-12 17:34:58 +00001694- Change the %s format specifier for str objects so that it returns a
1695 unicode instance if the argument is not an instance of basestring and
1696 calling __str__ on the argument returns a unicode instance.
1697
Tim Petersf4e69282006-02-27 17:15:31 +00001698- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1699 current thread state when the auto-GIL-state machinery knows about
1700 it (since the thread state is being deleted, continuing to remember it
1701 can't help, but can hurt if another thread happens to get created with
1702 the same thread id).
1703
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001704Extension Modules
1705-----------------
1706
Georg Brandl43f08a82006-03-31 18:01:16 +00001707- Patch #1380952: fix SSL objects timing out on consecutive read()s

1710
Anthony Baxterfa869072006-03-20 05:21:58 +00001711- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1712 In addition, the existing ulaw code was updated.
1713
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001714- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001715 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001716
Neal Norwitz10be10c2006-03-16 06:50:13 +00001717- Everything under lib-old was removed. This includes the following modules:
1718 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001719 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001720 util, whatsound, whrandom, zmod
1721
1722- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1723
1724- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001725 is deprecated. The undocumented re.engine variable no longer exists.
1726
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001727- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1728 SS2 (single-shift 2) escape sequences correctly.
1729
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001730- The unicodedata module was updated to the 4.1 version of the Unicode
1731 database. The 3.2 version is still available as unicodedata.db_3_2_0
1732 for applications that require this specific version (such as IDNA).
1733
Neal Norwitzb62c4332006-03-04 18:35:47 +00001734- The timing module is no longer built by default. It was deprecated
1735 in PEP 4 in Python 2.0 or earlier.
1736
Guido van Rossum1968ad32006-02-25 22:38:04 +00001737- Patch 1433928: Added a new type, defaultdict, to the collections module.
1738 This uses the new __missing__ hook behavior added to dict (see above).
1739
Georg Brandldbd83392006-02-20 09:42:33 +00001740- Bug #854823: socketmodule now builds on Sun platforms even when
1741 INET_ADDRSTRLEN is not defined.
1742
Georg Brandlf4f44152006-02-18 22:29:33 +00001743- Patch #1393157: os.startfile() now has an optional argument to specify
1744 a "command verb" to invoke on the file.
1745
Neal Norwitz082b2df2006-02-07 07:04:46 +00001746- Bug #876637, prevent stack corruption when socket descriptor
1747 is larger than FD_SETSIZE.
1748
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001749- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1750 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1751 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1752
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001753- Patch #1422385: The nis module now supports access to domains other
1754 than the system default domain.
1755
Martin v. Löwis14694662006-02-03 12:54:16 +00001756- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1757 are reported, the limit on path name lengths is removed, and stat reports
1758 WindowsError now (instead of OSError).
1759
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001760- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1761
Neal Norwitz62a21122006-01-25 05:21:55 +00001762- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1763 before the env.
1764

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001897
Nick Coghlan43832302006-04-23 17:04:07 +00001898- PEP 338: new module runpy defines a run_module function to support
1899 executing modules which provide access to source code or a code object
1900 via the PEP 302 import mechanisms.
1901

1910 in attribute values.
1911
Anthony Baxterc51ee692006-04-01 00:57:31 +00001912- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001913 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001914 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001915 module will not be built.
1916
Tim Petersc17976e2006-04-01 00:26:53 +00001917- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1918 aren't officially supported here, and trying to use them will probably
1919 raise an exception some day. But dicts have been allowed, and "mostly
1920 worked", so support for them won't go away without warning.
1921
Georg Brandl338ef7d2006-03-31 18:42:16 +00001922- Bug #1445068: getpass.getpass() can now be given an explicit stream

1940
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001941- email 4.0 package now integrated. This is largely the same as the email 3.0
1942 package that was included in Python 2.3, except that PEP 8 module names are
1943 now used (e.g. mail.message instead of email.Message). The MIME classes
1944 have been moved to a subpackage (e.g. email.mime.text instead of
1945 email.MIMEText). The old names are still supported for now. Several
1946 deprecated Message methods have been removed and lots of bugs have been
1947 fixed. More details can be found in the email package documentation.
1948
Walter Dörwald40108c92006-03-27 08:15:44 +00001949- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1950 (a subclass of tuple) that provides incremental decoders and encoders
1951 (a way to use stateful codecs without the stream API). Python functions
1952 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1953 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1954 have been added.

1957 a ValueError instead of a StopIteration now (like file and cString.String do).
1958 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1959 called before (like file and StringIO.StringIO do).

Neal Norwitz338e7862005-12-23 21:27:46 +00002028- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2029 LoadError as documented, instead of IOError. For compatibility,
2030 LoadError subclasses IOError.
2031
Brett Cannon3cbd0382005-12-16 22:49:23 +00002032- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002033 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2034 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2035 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2036 Ronald L. Rivest offered this advice for Python:
2037
2038 "The consensus of researchers in this area (at least as
2039 expressed at the NIST Hash Function Workshop 10/31/05),
2040 is that SHA-256 is a good choice for the time being, but
2041 that research should continue, and other alternatives may
2042 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002043
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002044- Added a subset of Fredrik Lundh's ElementTree package. Available

2086
Georg Brandl532efab2005-08-24 22:34:21 +00002087- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002088 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00002089
Georg Brandlb9256022005-08-24 18:46:39 +00002090- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2091 ContentTooShortException, when the actually downloaded size does not
2092 match the Content-Length header.
2093

2097 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002098 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002099

2113
Georg Brandla4a8b822005-07-15 09:13:21 +00002114- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2115 parameter, but uses the usual "kwargs=None".
2116
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002117- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2121 to W3C name (404 -> 'Not Found'). RFE #1216944.
2122
Georg Brandl9e43acf2005-07-04 17:16:07 +00002123- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2124 as this can cause problems with apps closing all file descriptors.

2137 Bug #1224621.
2138
Raymond Hettinger68c04532005-06-10 11:05:19 +00002139- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002140 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002141 the generate_tokens() function now accepts a callable argument that
2142 terminates by raising StopIteration.
2143
Georg Brandl9166e1a2005-06-04 09:20:03 +00002144- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2148
Skip Montanaro174dd222005-05-14 20:54:16 +00002149- Patch #1120353: The xmlrpclib module provides better, more transparent,
2150 support for datetime.{datetime,date,time} objects. With use_datetime set
2151 to True, applications shouldn't have to fiddle with the DateTime wrapper
2152 class at all.
2153
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002154- distutils.commands.upload was added to support uploading distribution

2156
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002157- distutils.commands.register now encodes the data as UTF-8 before posting
2158 them to PyPI.
2159
Raymond Hettinger267b8682005-03-27 10:47:39 +00002160- decimal operator and comparison methods now return NotImplemented
2161 instead of raising a TypeError when interacting with other types. This
2162 allows other classes to implement __radd__ style methods and have them
2163 work as expected.
2164
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002165- Bug #1163325: Decimal infinities failed to hash. Attempting to
2166 hash a NaN raised an InvalidOperation instead of a TypeError.
2167
Tim Petersecc6e6a2005-07-10 22:30:55 +00002168- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002169 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2170

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002180 profile.py if available.
2181
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002182- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2183

2188
Martin v. Löwise869eb12005-03-03 09:46:07 +00002189- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2190
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002191- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2192
Martin v. Löwisdf241532005-03-03 08:17:42 +00002193- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2194
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002195- Patch #1104111: Alter setup.py --help and --help-commands.
2196

2198
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002199- Patch #1049151: xdrlib now unpacks booleans as True or False.
2200

2202
Guido van Rossumd0641422005-02-03 15:01:24 +00002203- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2204 disables recursive traversal through instance attributes, which can
2205 be exploited in various ways.
2206
Tim Peterse3547fd2005-12-16 23:13:57 +00002207- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002208 flags on the HTTP listening socket.
2209
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002210- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2211 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2212
Fred Drakefbdeaad2006-07-29 16:56:15 +00002213- Patches #893642, #1039083: add allow_none, encoding arguments to
2214 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002215
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002216- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002218- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2219
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002220- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2221
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002222- Enhancements to the csv module:
2223
2224 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002225 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002226 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002227 + Dialect parameter parsing has been re-implemented to improve error
2228 reporting.
2229 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2230 dictates.
2231 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002232 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002233 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002234 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2235 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002236 + reader now allows \r characters to be quoted (previously it only allowed
2237 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002238 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002239 + Dialect classes passed to the module are no longer instantiated by
2240 the module before being parsed (the former validation scheme required
2241 this, but the mechanism was unreliable).
2242 + The dialect registry now contains instances of the internal
2243 C-coded dialect type, rather than references to python objects.
2244 + the internal c-coded dialect type is now immutable.
2245 + register_dialect now accepts the same keyword dialect specifications
2246 as the reader and writer, allowing the user to register dialects
2247 without first creating a dialect class.
2248 + a configurable limit to the size of parsed fields has been added -
2249 previously, an unmatched quote character could result in the entire
2250 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002251 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002252 the parser field size limit (returning the former limit). The initial
2253 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002254 + A line_num attribute has been added to the reader object, which tracks
2255 the number of lines read from the source iterator. This is not
2256 the same as the number of records returned, as records can span
2257 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002258 + reader and writer objects were not being registered with the cyclic-GC.
2259 This has been fixed.
2260
Brett Cannone6539c42005-01-08 02:43:53 +00002261- _DummyThread objects in the threading module now delete self.__block that is
2262 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2263 lock primitives tend to be limited in number and thus should not be wasted on
2264 a _DummyThread object. Fixes bug #1089632.
2265
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002266- The imghdr module now detects Exif files.
2267
Raymond Hettinger6065d322004-12-20 23:51:53 +00002268- StringIO.truncate() now correctly adjusts the size attribute.
2269 (Bug #951915).
2270
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002271- locale.py now uses an updated locale alias table (built using
2272 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2273 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002274 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002275
Raymond Hettinger3557f422004-12-07 12:02:02 +00002276- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2277
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002278- the pickle module no longer accepts the deprecated None option in the
2279 args tuple returned by __reduce__().
2280
Brett Cannon84667c02004-12-07 03:25:18 +00002281- optparse now optionally imports gettext. This allows its use in setup.py.
2282
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002283- the pickle module no longer uses the deprecated bin parameter.
2284
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002285- the shelve module no longer uses the deprecated binary parameter.
2286
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002287- the pstats module no longer uses the deprecated ignore() method.
2288
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002289- the filecmp module no longer uses the deprecated use_statcache argument.
2290
Raymond Hettinger664347b2004-12-04 21:21:53 +00002291- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2292 extended or overridden by subclasses. Formerly, the subclassed method would
2293 be ignored by the rest of the module. (Bug #1078905).
2294
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002295- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002296 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002297
Walter Dörwald36733692004-12-22 12:50:50 +00002298- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2299 once when a size argument is given. This prevents a buffer overflow in the
2300 tokenizer with very long source lines.
2301
Barry Warsaw538561e2006-01-01 21:48:54 +00002302- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2303 immediately after creating the object, without any intervening
2304 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002305
Skip Montanaro05885812005-01-16 20:48:27 +00002306- The reconvert.quote function can now emit triple-quoted strings. The
2307 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002308
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002309- ``UserString.MutableString`` now supports negative indices in
2310 ``__setitem__`` and ``__delitem__``
2311
Greg Ward40407942005-03-05 02:53:17 +00002312- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2313 correctly.
2314
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002315- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2316 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2317 character even if the user has passed a size parameter to get a proper
2318 line ending. Remove the special handling of a "\r\n" that has been split
2319 between two lines.
2320
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002321- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2322 about illegal code points. The codec now supports PEP 293 style error
2323 handlers.
2324
Walter Dörwald78a78b02005-09-01 12:04:29 +00002325- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002326 from the input stream, so that the output is a byte string in the correct
2327 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002328
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002329- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2330 considering it exactly like a '*'.
2331
Walter Dörwald007f8df2005-10-09 19:42:27 +00002332- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2333 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002334
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002335- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2336
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002337- Patch #1413711: Certain patterns of differences were making difflib
2338 touch the recursion limit.
2339
Walter Dörwald58917a62006-03-31 15:26:22 +00002340- Bug #947906: An object oriented interface has been added to the calendar
2341 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002342 called as a script (e.g. via ``python -mcalendar``). Localized month and
2343 weekday names can be ouput (even if an exotic encoding is used) using
2344 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002346Build
2347-----
2348
Neal Norwitz602d3392006-03-31 08:21:40 +00002349- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2350 by using -mieee gcc option.
2351

2353
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002354- Build support for Win64-AMD64 was added.
2355
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002356- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2357
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002358- Patch #881820: look for openpty and forkpty also in libbsd.
2359
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002360- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2361 The zlib module is now builtin on Windows.
2362
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002363- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2364
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002365- Bug #1189330: configure did not correctly determine the necessary
2366 value of LINKCC if python was built with GCC 4.0.
2367
Trent Mick8321b422005-07-26 02:29:21 +00002368- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2369 vulnerability in zlib 1.2.1 and 1.2.2.
2370
Brett Cannon08cd5982005-04-24 22:26:38 +00002371- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2372 flags that change binary compatibility. Changes were also made to
2373 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002374 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002375
Bob Ippolitoed233462005-03-29 13:47:59 +00002376- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2377 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2378 no longer exists). This configure patch makes things right.
2379
Martin v. Löwise2713be2005-03-08 15:03:08 +00002380- Bug #1158607: Build with --disable-unicode again.
2381
Brett Cannon46d96232005-02-16 00:07:19 +00002382- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2383 defined. Discovered as a result of not being able to build on OS X.
2384
Brett Cannon516592f2004-12-07 00:42:59 +00002385- setup.py now uses the directories specified in LDFLAGS using the -L option
2386 and in CPPFLAGS using the -I option for adding library and include
2387 directories, respectively, for compiling extension modules against. This has
2388 led to the core being compiled using the values in CPPFLAGS. It also removes
2389 the need for the special-casing of both DarwinPorts and Fink for darwin since
2390 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2391 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2392 Fink, ``-I/opt/local/include`` for DarwinPorts).
2393
Brett Cannon43802422005-02-10 20:48:03 +00002394- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2395 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2396 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2397 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002399C API
2400-----
2401
Tim Petersc9d78aa2006-03-26 23:27:58 +00002402- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2403 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2404 is obtained via the ``PyObject_`` family, it must be released via the
2405 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2406 always been officially true, but when Python's small-object allocator was
2407 introduced, an attempt was made to cater to a few extension modules
2408 discovered at the time that obtained memory via ``PyObject_New`` but
2409 released it via ``PyMem_DEL``. It's years later, and if such code still
2410 exists it will fail now (probably with segfaults, but calling wrong
2411 low-level memory management functions can yield many symptoms).
2412
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002413- Added a C API for set and frozenset objects.
2414
Raymond Hettinger66517482004-12-03 11:45:13 +00002415- Removed PyRange_New().
2416
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002417- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2418 mapping argument now. This string is used as a mapping table. Byte values
2419 greater than the length of the string and 0xFFFE are treated as undefined
2420 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002426- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002427
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002428- Patch #1276356: New resource "urlfetch" is implemented. This enables
2429 even impatient people to run tests that require remote files.
