310 - iso2022_jp_2 codec now encodes into G0 for KS X 1001, GB2312
311 codepoints to conform the standard.
312 - iso2022_jp_3 and iso2022_jp_2004 codec can encode JIS X 0213:2
313 codepoints now.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000367
368Core and builtins
369-----------------
370
Neal Norwitz24b6f202006-09-05 04:43:56 +0000371- Fix infinite recursion when subclassing long and overriding __hash__.
372
373- Fix concatenation (+=) of long strings.
374
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000375- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000376 compared equal or unequal to a string and a UnicodeDecodeError
377 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000378
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000379 Instead, the equal (==) and unequal (!=) comparison operators will
380 now issue a UnicodeWarning and interpret the two objects as
381 unequal. The UnicodeWarning can be filtered as desired using
382 the warning framework, e.g. silenced completely, turned into an
383 exception, logged, etc.
384
385 Note that compare operators other than equal and unequal will still
386 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000387
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000388- Fix segfault when doing string formatting on subclasses of long.
389
390- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
391 with new-style classes.
392
393- Fix bug related to __len__ functions returning negative values with
394 classic classes.
395
396- Patch #1538606, Fix __index__() clipping. There were some problems
397 discovered with the API and how integers that didn't fit into Py_ssize_t
398 were handled. This patch attempts to provide enough alternatives
399 to effectively use __index__.
400
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000401- Bug #1536021: __hash__ may now return long int; the final hash
402 value is obtained by invoking hash on the long int.
403
Thomas Hellerab1049c2006-08-08 17:37:00 +0000404- Bug #1536786: buffer comparison could emit a RuntimeWarning.
405
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000406- Bug #1535165: fixed a segfault in input() and raw_input() when
407 sys.stdin is closed.
408
Thomas Heller74d36f02006-08-04 18:17:40 +0000409- On Windows, the PyErr_Warn function is now exported from
410 the Python dll again.
411
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000412- Bug #1191458: tracing over for loops now produces a line event
413 on each iteration. Fixing this problem required changing the .pyc
414 magic number. This means that .pyc files generated before 2.5c1
415 will be regenerated.
416
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000417- Bug #1333982: string/number constants were inappropriately stored
418 in the byte code and co_consts even if they were not used, ie
419 immediately popped off the stack.
420
Georg Brandle9462c72006-08-04 18:03:37 +0000421- Fixed a reference-counting problem in property().

424Library
425-------
426
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000427- Fix a bug in the ``compiler`` package that caused invalid code to be
428 generated for generator expressions.
429
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000430- The distutils version has been changed to 2.5.0. The change to
431 keep it programmatically in sync with the Python version running
432 the code (introduced in 2.5b3) has been reverted. It will continue
433 to be maintained manually as static string literal.
434
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000435- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000436 and this cannot be converted to the required C type, an exception is
437 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000438 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000439
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000440- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000441 an exception.
442
Tim Peterscbdd3502006-09-05 01:47:53 +0000443- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000444 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000445 workarounds for clocks with low resolution, to stop the code yielding
446 duplicate UUIDs.
447
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000448- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
449 before raising SystemExit, allowing IDLE to honor quit() and exit().
450
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000451- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
452
Georg Brandl7a1af772006-08-14 21:55:28 +0000453- Patch #1536071: trace.py should now find the full module name of a
454 file correctly even on Windows.
455
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000456- logging's atexit hook now runs even if the rest of the module has
457 already been cleaned up.
458
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000459- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000460
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000461- Bug #1531405, format_exception no longer raises an exception if
462 str(exception) raised an exception.
463
Neil Schemenauer06ded092006-08-04 16:20:30 +0000464- Fix a bug in the ``compiler`` package that caused invalid code to be
465 generated for nested functions.

476 raises the correct exceptions.
477
Thomas Heller1ce433e2006-08-14 16:20:04 +0000478- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
479 '-no-stack-protector' compiler flag for OpenBSD has been removed.
480
Thomas Heller86720042006-08-14 11:17:48 +0000481- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
482 uses the _as_parameter_ attribute when objects are passed to foreign
483 function calls. The ctypes version number was changed to 1.0.1.
484
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000485- Bug #1530559, struct.pack raises TypeError where it used to convert.
486 Passing float arguments to struct.pack when integers are expected
487 now triggers a DeprecationWarning.
488
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000489

Neal Norwitza1f10902006-07-12 07:28:29 +0000536
537Core and builtins
538-----------------
539
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000540- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000541 returned a long (see PEP 353).
542
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000543- Bug #1515471: string.replace() accepts character buffers again.
544
Neal Norwitz07aadb12006-07-30 06:55:48 +0000545- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
546 This provides the proper warning for struct.pack().
547 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
548
Neal Norwitz0d62a062006-07-30 06:53:31 +0000549- Patch #1531113: Fix augmented assignment with yield expressions.
550 Also fix a SystemError when trying to assign to yield expressions.
551
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000552- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
553 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
554 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
555 excessive filesystem operations during imports.
556
Tim Petersbc24eee2006-07-27 01:14:53 +0000557- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
558 operations on signed longs that are formally undefined by C.
559 Unfortunately, at least one compiler now cares about that, so complicated
560 the code to make that compiler happy again.
561
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000562- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
563
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000564- Patch #1232023: Stop including current directory in search
565 path on Windows.
566
Neal Norwitze1fdb322006-07-21 05:32:28 +0000567- Fix some potential crashes found with failmalloc.
568
Neal Norwitze7563102006-07-17 01:00:16 +0000569- Fix warnings reported by Klocwork's static analysis tool.
570
Neal Norwitz84be93b2006-07-16 01:50:38 +0000571- Bug #1512814, Fix incorrect lineno's when code within a function
572 had more than 255 blank lines.
573
Georg Brandl9dceedb2006-07-12 15:31:17 +0000574- Patch #1521179: Python now accepts the standard options ``--help`` and
575 ``--version`` as well as ``/?`` on Windows.
576
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000577- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000578 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000579 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000580
Tim Peters112aad32006-07-19 00:03:19 +0000581- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000582 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000583 new ``sys._current_frames()`` returns a dictionary with one entry,
584 mapping the faux "thread id" 0 to the current frame.
585
Ronald Oussoren3075e162006-07-25 20:28:55 +0000586- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000587
Ronald Oussoren3075e162006-07-25 20:28:55 +0000588
Neal Norwitza1f10902006-07-12 07:28:29 +0000589Library
590-------
591
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000592- Correction of patch #1455898: In the mbcs decoder, set final=False
593 for stream decoder, but final=True for the decode function.
594
Georg Brandl07fec3a2006-08-01 18:49:24 +0000595- os.urandom no longer masks unrelated exceptions like SystemExit or
596 KeyboardInterrupt.
597
Tim Peters4643c2f2006-08-10 22:45:34 +0000598- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000599 shutil.copytree on Windows
600
Georg Brandle34ac7c2006-07-30 11:07:23 +0000601- Bug #1002398: The documentation for os.path.sameopenfile now correctly
602 refers to file descriptors, not file objects.
603
Tim Peterscbdd3502006-09-05 01:47:53 +0000604- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000605 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000606 #1513611, and probably others.
607
Georg Brandledd9b0d2006-07-29 09:33:26 +0000608- Bug #1441397: The compiler module now recognizes module and function
609 docstrings correctly as it did in Python 2.4.
610
Tim Peters6f681472006-07-27 23:44:37 +0000611- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
612 lost that tests are sorted by name before being run. This rarely
613 matters for well-written tests, but can create baffling symptoms if
614 side effects from one test to the next affect outcomes. ``DocTestFinder``
615 has been changed to sort the list of tests it returns.
616
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000617- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000618 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000619
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000620- Bug #978833: Really close underlying socket in _socketobject.close.
621
Georg Brandldb232dc2006-08-20 13:15:43 +0000622- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
623 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000624
Georg Brandlcf0c1722006-07-26 07:23:32 +0000625- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
626 to recursive calls and call it with the failing package name.
627
Martin v. Löwis0b483032006-07-25 09:53:12 +0000628- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
629
Georg Brandlc13c34c2006-07-24 14:09:56 +0000630- Patch #1515343: Fix printing of deprecated string exceptions with a
631 value in the traceback module.
632
Greg Ward48fae7a2006-07-23 16:05:51 +0000633- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
634
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000635- Patch #1524429: Use repr() instead of backticks in Tkinter again.
636
Brett Cannoncaebe222006-07-18 04:41:36 +0000637- Bug #1520914: Change time.strftime() to accept a zero for any position in its
638 argument tuple. For arguments where zero is illegal, the value is forced to
639 the minimum value that is correct. This is to support an undocumented but
640 common way people used to fill in inconsequential information in the time
641 tuple pre-2.4.
642
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000643- Patch #1220874: Update the binhex module for Mach-O.
644
Barry Warsawb110bad2006-07-21 14:51:07 +0000645- The email package has improved RFC 2231 support, specifically for
646 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
647 (name*0=<blah>) parameter continuations. This may change the types of
648 values returned from email.message.Message.get_param() and friends.
649 Specifically in some cases where non-encoded continuations were used,
650 get_param() used to return a 3-tuple of (None, None, string) whereas now it
651 will just return the string (since non-encoded continuations don't have
652 charset and language parts).
653
654 Also, whereas % values were decoded in all parameter continuations, they are
655 now only decoded in encoded parameter parts.
656
Ronald Oussoren3075e162006-07-25 20:28:55 +0000657- Bug #1517990: IDLE keybindings on MacOS X now work correctly
658
659- Bug #1517996: IDLE now longer shows the default Tk menu when a
660 path browser, class browser or debugger is the frontmost window on MacOS X
661
Barry Warsaw00decd72006-07-27 23:43:15 +0000662- Patch #1520294: Support for getset and member descriptors in types.py,
663 inspect.py, and pydoc.py. Specifically, this allows for querying the type
664 of an object against these built-in types and more importantly, for getting
665 their docstrings printed in the interactive interpreter's help() function.

670
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000671- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
672 a socket operation on a socket with a timeout, the exception will be
673 caught correctly. Previously, the exception was not caught.
674
Thomas Heller1393d6a2006-07-28 21:43:20 +0000675- Patch #1529514: The _ctypes extension is now compiled on more
676 openbsd target platforms.
677
Tim Peters9cab5932006-07-28 00:30:00 +0000678- The ``__reduce__()`` method of the new ``collections.defaultdict`` had

Thomas Hellerce049a02006-07-14 17:51:14 +0000686- Patch #1521817: Index range checking on ctypes arrays containing
687 exactly one element enabled again. This allows iterating over these
688 arrays, without the need to check the array size before.
689
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000690- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000691 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000692 /dev/null in certain cases; this is now fixed.
693
Thomas Heller47d7a062006-07-12 08:43:47 +0000694- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
695 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000696
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000697- Because of a misspelled preprocessor symbol, ctypes was always
698 compiled without thread support; this is now fixed.
699
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000700- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
701 methods now allow their database parameter to be None as the
702 sleepycat API allows.
703
Matt Flemingec926502006-07-28 11:27:27 +0000704- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
705 bluetooth API compared with Linux and FreeBSD.

708-----
709
710- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
711 how long the test file should take to play. Now accepts taking 2.93 secs
712 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
713
Georg Brandl4793aa32006-07-28 18:31:39 +0000714- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
715 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
716 run via ``regrtest.py``. Now they do.

725
726- PythonLauncher now works correctly when the path to the script contains
727 characters that are treated specially by the shell (such as quotes).
728
729- Bug #1527397: PythonLauncher now launches scripts with the working directory
730 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000731 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000732 expect.

742
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000743- Bug #1441486: The literal representation of -(sys.maxint - 1)
744 again evaluates to a int object, not a long.
745
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000746- Bug #1501934: The scope of global variables that are locally assigned
747 using augmented assignment is now correctly determined.
748
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000749- Bug #927248: Recursive method-wrapper objects can now safely
750 be released.
751
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000752- Bug #1417699: Reject locale-specific decimal point in float()
753 and atof().
754
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000755- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
756 omit a default "error" argument for NULL pointer. This allows
757 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000758
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000759- Bug #1519018: 'as' is now validated properly in import statements.
760
Neal Norwitz28746ab2006-07-09 22:14:42 +0000761- On 64 bit systems, int literals that use less than 64 bits are
762 now ints rather than longs.
763
Neal Norwitzed657552006-07-10 00:04:44 +0000764- Bug #1512814, Fix incorrect lineno's when code at module scope
765 started after line 256.
766
Tim Peters32a83612006-07-10 21:08:24 +0000767- New function ``sys._current_frames()`` returns a dict mapping thread
768 id to topmost thread stack frame. This is for expert use, and is
769 especially useful for debugging application deadlocks. The functionality
770 was previously available in Fazal Majid's ``threadframe`` extension
771 module, but it wasn't possible to do this in a wholly threadsafe way from
772 an extension.

819
Brett Cannon53ab5b72006-06-22 16:49:14 +0000820- Bug #1510580: The 'warnings' module improperly required that a Warning
821 category be either a types.ClassType and a subclass of Warning. The proper
822 check is just that it is a subclass with Warning as the documentation states.
823
Georg Brandlad29e632006-06-21 17:45:17 +0000824- The compiler module now correctly compiles the new try-except-finally
825 statement (bug #1509132).
826
Neal Norwitz60373cd2006-06-22 06:30:50 +0000827- The wsgiref package is now installed properly on Unix.

831
Gerhard Häring762fbd32006-07-02 17:48:30 +0000832- The sqlite3 module did cut off data from the SQLite database at the first

840 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
841 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000842
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000843- Assigning None to pointer type fields in ctypes structures possible
844 overwrote the wrong fields, this is fixed now.
845
846- Fixed a segfault in _ctypes when ctypes.wintypes were imported
847 on non-Windows platforms.
848
849- Bug #1518190: The ctypes.c_void_p constructor now accepts any
850 integer or long, without range checking.
851
852- Patch #1517790: It is now possible to use custom objects in the ctypes
853 foreign function argtypes sequence as long as they provide a from_param
854 method, no longer is it required that the object is a ctypes type.
855

874
Tim Peters32a83612006-07-10 21:08:24 +0000875- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000876 Previously, the slight difference could cause compilation errors of the
877 'zlib' module on systems with more than one version of zlib.
878
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000879- The MSI compileall step was fixed to also support a TARGETDIR

Neal Norwitz909eb122006-06-12 02:13:21 +0000920- Fix the socket tests so they can be run concurrently.
921
Neal Norwitzb9845e72006-06-12 02:11:18 +0000922- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000923 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000924
Brett Cannon22565aa2006-06-09 22:31:23 +0000925- Bug #532646: object.__call__() will continue looking for the __call__
926 attribute on objects until one without one is found. This leads to recursion
927 when you take a class and set its __call__ attribute to an instance of the
928 class. Originally fixed for classic classes, but this fix is for new-style.
929 Removes the infinite_rec_3 crasher.
930
Georg Brandl24250812006-06-09 18:45:48 +0000931- The string and unicode methods startswith() and endswith() now accept
932 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
933
Brett Cannonde3b0522006-06-08 17:00:45 +0000934- Buffer objects, at the C level, never used the char buffer
935 implementation even when the char buffer for the wrapped object was
936 explicitly requested (originally returned the read or write buffer).
937 Now a TypeError is raised if the char buffer is not present but is
938 requested.
939
Georg Brandlddbaa662006-06-04 21:56:52 +0000940- Patch #1346214: Statements like "if 0: suite" are now again optimized
941 away like they were in Python 2.4.
942
Georg Brandlb7c8f542006-05-27 12:30:25 +0000943- Builtin exceptions are now full-blown new-style classes instead of
944 instances pretending to be classes, which speeds up exception handling
945 by about 80% in comparison to 2.5a2.
946
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000947- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
948 Unicode 4.1.
949
Georg Brandlf4ef1162006-05-26 18:03:31 +0000950- Patch #921466: sys.path_importer_cache is now used to cache valid and
951 invalid file paths for the built-in import machinery which leads to
952 fewer open calls on startup.
953
Tim Peters696cf432006-05-24 21:10:40 +0000954- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
955 of-2 bases. The largest speedup is for inputs with about 1000 decimal
956 digits. Conversion from non-power-of-2 bases remains quadratic-time in
957 the number of input digits (it was and remains linear-time for bases
958 2, 4, 8, 16 and 32).
959
Tim Petersb713ec22006-05-23 18:45:30 +0000960- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
961 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
962 an integer close to ``sys.maxint``. This was repaired by patch
963 #1335972, which also gives a nice speedup.
964
Richard Jonescebbefc2006-05-23 18:28:17 +0000965- Patch #1337051: reduced size of frame objects.
966
967- PyErr_NewException now accepts a tuple of base classes as its
968 "base" parameter.
969
Richard Jones7c88dcc2006-05-23 10:37:38 +0000970- Patch #876206: function call speedup by retaining allocated frame
971 objects.
972
Georg Brandl7b90e162006-05-18 07:01:27 +0000973- Bug #1462152: file() now checks more thoroughly for invalid mode
974 strings and removes a possible "U" before passing the mode to the
975 C library function.
976
Neal Norwitz1004a532006-05-15 07:17:23 +0000977- Patch #1488312, Fix memory alignment problem on SPARC in unicode
978
Neal Norwitz373f0a72006-05-15 07:04:36 +0000979- Bug #1487966: Fix SystemError with conditional expression in assignment
980
Martin v. Löwis879768d2006-05-11 13:28:43 +0000981- WindowsError now has two error code attributes: errno, which carries
982 the error values from errno.h, and winerror, which carries the error
983 values from winerror.h. Previous versions put the winerror.h values
984 (from GetLastError()) into the errno attribute.
985
Martin v. Löwis77736712006-05-04 05:51:03 +0000986- Patch #1475845: Raise IndentationError for unexpected indent.
987
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000988- Patch #1479181: split open() and file() from being aliases for each other.
989
Tim Peters44bd9862006-06-01 13:49:23 +0000990- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
991 methods were always silently ignored by dictionaries when comparing keys.
992 They are now passed through (except when using the C API function
993 ``PyDict_GetItem()``, whose semantics did not change).
994
995- Bug #1456209: In some obscure cases it was possible for a class with a
996 custom ``__eq__()`` method to confuse dict internals when class instances
997 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
998 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001000Extension Modules
1001-----------------
1002
Trent Mick960a3f82006-06-28 20:30:41 +00001003- Bug #1295808: expat symbols should be namespaced in pyexpat
1004
1005- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1006
Brett Cannon6ee7d012006-06-08 16:23:04 +00001007- Change binascii.hexlify to accept a read-only buffer instead of only a char
1008 buffer and actually follow its documentation.
1009
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001010- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1011
Nick Coghlanc649ec52006-05-29 12:43:05 +00001012- Patch #1478788 (modified version): The functional extension module has
1013 been renamed to _functools and a functools Python wrapper module added.
1014 This provides a home for additional function related utilities that are
1015 not specifically about functional programming. See PEP 309.
1016
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001017- Patch #1493701: performance enhancements for struct module.
1018
Georg Brandl378d5922006-05-17 14:26:50 +00001019- Patch #1490224: time.altzone is now set correctly on Cygwin.
1020
Georg Brandl8d3342b2006-05-16 07:38:27 +00001021- Patch #1435422: zlib's compress and decompress objects now have a
1022 copy() method.
1023
Andrew MacIntyre92913322006-06-13 15:04:24 +00001024- Patch #1454481: thread stack size is now tunable at runtime for thread
1025 enabled builds on Windows and systems with Posix threads support.
1026
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001027- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1028 (up to the system limit of 32K characters).
1029
1030- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1031 As a result, these functions now raise WindowsError instead of OSError.
1032
Tim Peters7a822da2006-05-25 21:50:17 +00001033- ``time.clock()`` on Win64 should use the high-performance Windows
1034 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1035 Windows platforms).
1036
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001037- Calling Tk_Init twice is refused if the first call failed as that
1038 may deadlock.
1039
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001040- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1041 accept it without potentially using an uninitialized pointer.
1042
1043- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1044 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1045 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001046
Gregory P. Smith372b5832006-06-05 18:48:21 +00001047- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001048 [pybsddb project SF patch number 1466734]
1049
Gregory P. Smith372b5832006-06-05 18:48:21 +00001050- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1051 parameter is supplied. [SF pybsddb bug #1477863]
1052
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001053- bsddb: the __len__ method of a DB object has been fixed to return correct
1054 results. It could previously incorrectly return 0 in some cases.
1055 Fixes SF bug 1493322 (pybsddb bug 1184012).
1056
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001057- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1058 aborts the db transaction safely when a modifier callback fails.
1059 Fixes SF python patch/bug #1408584.
1060
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001061- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001062 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001063 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1064 database calls that would previously deadlock. [SF python bug #775414]
1065
Vinay Sajip28e57612006-07-01 10:45:20 +00001066- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001067
Walter Dörwald4994d952006-06-19 08:07:50 +00001068- Patch #1506645: add Python wrappers for the curses functions
1069 is_term_resized, resize_term and resizeterm.

1073
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001074- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1075 functions.
1076
Martin v. Löwis3798da02006-06-17 18:44:27 +00001077- Patch #812986: Update turtle output even if not tracing.
1078
Vinay Sajip28e57612006-07-01 10:45:20 +00001079- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001080 Tkinter.BaseWidget.
1081
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001082- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1083
Martin v. Löwis337487e2006-06-17 09:15:14 +00001084- Patch #763580: Add name and value arguments to Tkinter variable
1085 classes.
1086
Georg Brandl83cc0d02006-06-14 08:50:03 +00001087- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1088 mime.types file for determining MIME types.
1089
Georg Brandl2605ca82006-06-14 06:08:31 +00001090- Bug #1339007: Shelf objects now don't raise an exception in their
1091 __del__ method when initialization failed.
1092
Martin v. Löwisd8251432006-06-14 05:21:04 +00001093- Patch #1455898: The MBCS codec now supports the incremental mode for
1094 double-byte encodings.
1095
Tim Peters43898b42006-06-14 04:09:25 +00001096- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1097 guarantee that adjacent triples in the return list always describe
1098 non-adjacent blocks. Previously, a pair of matching blocks could end
1099 up being described by multiple adjacent triples that formed a partition
1100 of the matching pair.
1101
Greg Ward0e0c9f42006-06-11 16:24:11 +00001102- Bug #1498146: fix optparse to handle Unicode strings in option help,
1103 description, and epilog.
1104
Greg Wardd1c797e2006-06-11 14:42:41 +00001105- Bug #1366250: minor optparse documentation error.
1106
Greg Ward7f547402006-06-11 00:40:49 +00001107- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1108 clarify docs.
1109
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001110- The wsgiref package has been added to the standard library.
1111
Nick Coghlan676725d2006-06-08 13:54:49 +00001112- The functions update_wrapper() and wraps() have been added to the functools
1113 module. These make it easier to copy relevant metadata from the original
1114 function when writing wrapper functions.
1115
Tim Petersd6a9eef2006-06-05 01:48:21 +00001116- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1117 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001118
Martin v. Löwis3f767792006-06-04 19:36:28 +00001119- Patch #1359618: Speed up charmap encoder by using a trie structure
1120 for lookup.
1121
Tim Petersd609b1a2006-06-02 23:22:51 +00001122- The functions in the ``pprint`` module now sort dictionaries by key
1123 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1124 if and only if its display required more than one line, although that
1125 wasn't documented. The new behavior increases predictability; e.g.,
1126 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1127
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001128- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1129 (thanks for J. J. Lee).
1130
Georg Brandl2b330372006-05-28 20:23:12 +00001131- Patch #1496206: improve urllib2 handling of passwords with respect to
1132 default HTTP and HTTPS ports.
1133
George Yoshidaf3c65de2006-05-28 16:39:09 +00001134- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1135
Bob Ippolito7298f272006-05-23 18:43:47 +00001136- Patch #1281707: speed up gzip.readline.
1137
Georg Brandlb89316f2006-05-17 15:51:16 +00001138- Patch #1180296: Two new functions were added to the locale module:
1139 format_string() to get the effect of "format % items" but locale-aware,
1140 and currency() to format a monetary number with currency sign.
1141
Georg Brandle3a25832006-05-17 14:56:04 +00001142- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1143 and several features added, such as speed and geometry control.
1144
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001145- Patch #1488881: add support for external file objects in bz2 compressed
1146 tarfiles.
1147
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001148- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1149 stdout arguments, making it possible to redirect input and output
1150 for remote debugging.
1151
1152- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1153 a couple of issues, notably handling of long file names using the
1154 GNU LONGNAME extension.
1155
1156- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1157 new flag when ``name`` is already the name of an option flag.
1158
1159- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1160 package.
1161
1162- Patch #1472854: make the rlcompleter.Completer class usable on non-
1163 UNIX platforms.
1164
1165- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1166
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001167- Bug #1472827: correctly escape newlines and tabs in attribute values in

1200
1201*Release date: 27-APR-2006*

1203Core and builtins
1204-----------------
1205
Thomas Heller1b046642006-04-18 18:51:06 +00001206- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1207 by converting these apis from macros into exported functions again:
1208
1209 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1210 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1211 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1213 PyRun_String Py_CompileString
1214
Martin v. Löwis45294a92006-04-18 06:24:08 +00001215- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1216
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001217- All uses of PyStructSequence_InitType have been changed to initialize
1218 the type objects only once, even if the interpreter is initialized
1219 multiple times.
1220
Neal Norwitz61546162006-04-14 05:20:28 +00001221- Bug #1454485, array.array('u') could crash the interpreter. This was
1222 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1223 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1224
1225- Py_UNICODE is unsigned. It was always documented as unsigned, but
1226 due to a bug had a signed value in previous versions.

Tim Peters3a5e8b12006-04-11 01:44:07 +00001228- Patch #837242: ``id()`` of any Python object always gives a positive
1229 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1230 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001231 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001232 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001233
Tim Peters3a5e8b12006-04-11 01:44:07 +00001234 def __hash__(self):
1235 return id(self) # WRONG
1236
1237 because a hash result must be a (short) Python int but it was always
1238 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001239 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001240 was always usable as a hash value before this patch. That's no longer
1241 necessarily so.
1242
1243- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001244 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001245 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001246 #1454844)
1247
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001248- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1249 involving generators that have paused outside of any ``try`` or ``with``
1250 blocks. (In 2.5a1, a paused generator that was part of a reference
1251 cycle could not be garbage collected, regardless of whether it was
1252 paused in a ``try`` or ``with`` block.)

1259
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001260- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1261 fails with an error condition.
1262
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001263- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1264
1265- Bug #1117761: bsddb.*open() no longer raises an exception when using
1266 the cachesize parameter.
1267
1268- Bug #1149413: bsddb.*open() no longer raises an exception when using
1269 a temporary db (file=None) with the 'n' flag to truncate on open.
1270
1271- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1272 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001273
Armin Rigoa9017c32006-04-19 11:50:27 +00001274- Patch #1062014: AF_UNIX sockets under Linux have a special
1275 abstract namespace that is now fully supported.

1279
Peter Astrand7d1d4362006-07-14 14:04:45 +00001280- Bug #1223937: subprocess.CalledProcessError reports the exit status
1281 of the process using the returncode attribute, instead of
1282 abusing errno.
1283
Tim Peters711bf302006-04-25 03:31:36 +00001284- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1285 a doctest to be skipped (the code is not run, and the expected output
1286 or exception is ignored).
1287
Nick Coghlanda2268f2006-04-24 04:37:15 +00001288- Fixed contextlib.nested to cope with exceptions being raised and
1289 caught inside exit handlers.
1290
Greg Wardab05edc2006-04-23 03:47:58 +00001291- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1292 hex, octal, or binary; add ``append_const`` action; keep going if
1293 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1294 added ``epilog`` for better help generation).
1295
Tim Peters21fbd572006-04-21 21:18:10 +00001296- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1297 called from a thread spawned as a side effect of importing a module.
1298
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001299- The pydoc module now supports documenting packages contained in
1300 .zip or .egg files.
1301
1302- The pkgutil module now has several new utility functions, such
1303 as ``walk_packages()`` to support working with packages that are either
1304 in the filesystem or zip files.
1305
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001306- The mailbox module can now modify and delete messages from
1307 mailboxes, in addition to simply reading them. Thanks to Gregory
1308 K. Johnson for writing the code, and to the 2005 Google Summer of
1309 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001310

1333
Skip Montanaro262fb922006-04-21 02:31:07 +00001334- The pstats.Stats class accepts an optional stream keyword argument to
1335 direct output to an alternate file-like object.
1336
Anthony Baxter51bcb682006-04-05 14:51:42 +00001337Build
1338-----
1339
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001340- The Makefile now has a reindent target, which runs reindent.py on
1341 the library.
1342
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001343- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001346
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001347- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1348 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001349 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001350 CXX from --with-cxx-main, see description in README.
1351
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001352- Patch #1429775: Link extension modules with the shared libpython.
1353
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001354- Fixed a libffi build problem on MIPS systems.
1355
Tim Peters8931ff12006-05-13 23:28:20 +00001356- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1357 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1358 and "%zu" for unsigned integers of type ``size_t``.
1359
Anthony Baxter51bcb682006-04-05 14:51:42 +00001360Tests
1361-----
1362
Nick Coghlanda2268f2006-04-24 04:37:15 +00001363- test_contextlib now checks contextlib.nested can cope with exceptions
1364 being raised and caught inside exit handlers.
1365
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001366- test_cmd_line now checks operation of the -m and -c command switches
1367
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001368- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1369 it separately and by hand. It also wasn't cleaning up its changes to
1370 the current Decimal context.
1371
Thomas Woutersabd08882006-04-26 15:53:30 +00001372- regrtest.py now has a -M option to run tests that test the new limits of
1373 containers, on 64-bit architectures. Running these tests is only sensible
1374 on 64-bit machines with more than two gigabytes of memory. The argument
1375 passed is the maximum amount of memory for the tests to use.

1384-------------
1385
Tim Petersb06d28c2006-05-12 01:57:59 +00001386- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1387
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001388- PEP 343: Added Context Types section to the library reference
1389 and attempted to bring other PEP 343 related documentation into
1390 line with the implementation and/or python-dev discussions.
1391
Tim Peters8dc73d22006-04-24 02:03:16 +00001392- Bug #1337990: clarified that ``doctest`` does not support examples
1393 requiring both expected output and an exception.

1397=================================
1398
Anthony Baxterebed3f62006-04-03 15:03:44 +00001399*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001400
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001401Core and builtins
1402-----------------
1403
Nick Coghlan43832302006-04-23 17:04:07 +00001404- PEP 338: -m command line switch now delegates to runpy.run_module
1405 allowing it to support modules in packages and zipfiles
1406
Martin v. Löwisc661b882006-04-20 04:54:23 +00001407- On Windows, .DLL is not an accepted file name extension for
1408 extension modules anymore; extensions are only found if they
1409 end in .PYD.
1410
Martin v. Löwisea62d252006-04-03 10:56:49 +00001411- Bug #1421664: sys.stderr.encoding is now set to the same value as
1412 sys.stdout.encoding.
1413
Neal Norwitz92e212f2006-04-03 04:48:37 +00001414- __import__ accepts keyword arguments.
1415
Georg Brandlccadf842006-03-31 18:54:53 +00001416- Patch #1460496: round() now accepts keyword arguments.
1417
Anthony Baxter262c00a2006-03-30 10:53:17 +00001418- Fixed bug #1459029 - unicode reprs were double-escaped.
1419
Hye-Shik Changd478f342006-03-23 12:32:36 +00001420- Patch #1396919: The system scope threads are reenabled on FreeBSD
1421 5.4 and later versions.
1422
Neal Norwitze98ccf62006-03-23 05:39:47 +00001423- Bug #1115379: Compiling a Unicode string with an encoding declaration
1424 now gives a SyntaxError.
1425
Georg Brandlabd1ff82006-03-18 07:59:59 +00001426- Previously, Python code had no easy way to access the contents of a
1427 cell object. Now, a ``cell_contents`` attribute has been added
1428 (closes patch #1170323).
1429
Tim Peterscf79aac2006-03-16 01:14:46 +00001430- Patch #1123430: Python's small-object allocator now returns an arena to
1431 the system ``free()`` when all memory within an arena becomes unused
1432 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1433 freed. Some applications will see a drop in virtual memory size now,
1434 especially long-running applications that, from time to time, temporarily
1435 use a large number of small objects. Note that when Python returns an
1436 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001437 platform C library will in turn return that memory to the operating system.
1438 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001439 appears to be effective at least on Microsoft C and gcc-based systems.
1440 Thanks to Evan Jones for hard work and patience.
1441
Georg Brandl533ff6f2006-03-08 18:09:27 +00001442- Patch #1434038: property() now uses the getter's docstring if there is
1443 no "doc" argument given. This makes it possible to legitimately use
1444 property() as a decorator to produce a read-only property.
1445
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001446- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1447 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1448 of requiring an int or long in slicing and a few other contexts, enabling
1449 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1450
Neal Norwitz995acdf2006-03-07 05:01:00 +00001451- Fixed various bugs reported by Coverity's Prevent tool.
1452
Brett Cannonbf364092006-03-01 04:25:17 +00001453- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1454 new exception base class, BaseException, which has a new message attribute.
1455 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1456 Raising a string exception now raises a DeprecationWarning.
1457
Thomas Woutersfb609f42006-02-28 16:37:25 +00001458- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1459 explicitly relative, using 'from .module import name' to mean 'from the same
1460 package as this module is in. Imports without dots still default to the
1461 old relative-then-absolute, unless 'from __future__ import
1462 absolute_import' is used.
1463
Brett Cannona7446e32006-02-27 23:39:10 +00001464- Properly check if 'warnings' raises an exception (usually when a filter set
1465 to "error" is triggered) when raising a warning for raising string
1466 exceptions.
1467
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001468- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001469 The name was removed from Include/code.h.
1470
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001471- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001472
Guido van Rossum1968ad32006-02-25 22:38:04 +00001473- Patch 1433928:
1474 - The copy module now "copies" function objects (as atomic objects).
1475 - dict.__getitem__ now looks for a __missing__ hook before raising
1476 KeyError.
1477
Tim Peters84ef21c2006-02-28 20:39:06 +00001478- PEP 343: with statement implemented. Needs ``from __future__ import
1479 with_statement``. Use of 'with' as a variable will generate a warning.
1480 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001481 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001482 The following objects have __context__ methods:
1483 - The built-in file type.
1484 - The thread.LockType type.
1485 - The following types defined by the threading module:
1486 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1487 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001488
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001489- Fix the encodings package codec search function to only search
1490 inside its own package. Fixes problem reported in patch #1433198.
1491
1492 Note: Codec packages should implement and register their own
1493 codec search function. PEP 100 has the details.
1494
Tim Peters9ea89d22006-06-04 03:26:02 +00001495- PEP 353: Using ``Py_ssize_t`` as the index type.
1496
1497- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1498 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1499 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1500 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1501 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001502
Neal Norwitzfc76d632006-01-10 06:03:13 +00001503- Patch #1400181, fix unicode string formatting to not use the locale.
1504 This is how string objects work. u'%f' could use , instead of .
1505 for the decimal point. Now both strings and unicode always use periods.
1506
Neal Norwitz671b9e32006-01-09 07:07:12 +00001507- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1508 configure would break checking curses.h.
1509
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001510- Bug #959576: The pwd module is now builtin. This allows Python to be
1511 built on UNIX platforms without $HOME set.
1512
Neal Norwitzc10978f2005-12-19 06:07:16 +00001513- Bug #1072182, fix some potential problems if characters are signed.
1514
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001515- Bug #889500, fix line number on SyntaxWarning for global declarations.
1516
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001517- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1518
Neal Norwitze7214a12005-12-18 05:03:17 +00001519- Support for converting hex strings to floats no longer works.
1520 This was not portable. float('0x3') now raises a ValueError.
1521
Barry Warsaw2a38a862005-12-18 01:27:35 +00001522- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001523 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001524 is now displayed in interactive prompt banner.
1525
Georg Brandlfa166682005-12-17 21:45:17 +00001526- Implementation of PEP 341 - Unification of try/except and try/finally.
1527 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001528 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001529
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001530- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1531 now encodes backslash correctly.
1532
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001533- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1534
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001535- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001536 and long longs.
1537
Neal Norwitz67715f02005-11-09 06:59:35 +00001538- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001539 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001540 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001541
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001542- Replaced most Unicode charmap codecs with new ones using the
1543 new Unicode translate string feature in the builtin charmap
1544 codec; the codecs were created from the mapping tables available
1545 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1546 encodings now include a mapping for the Apple logo)
1547
Tim Peterse3547fd2005-12-16 23:13:57 +00001548- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001549
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001550- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001551
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001552- A new AST parser implementation was completed. The abstract
1553 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001554 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001556- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001557 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1558
Neal Norwitz708e51a2005-10-03 04:48:15 +00001559- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1560
Neal Norwitz11bd1192005-10-03 00:54:56 +00001561- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1562 Provide a warning when a directory is passed on the command line.
1563
Neal Norwitz40d37812005-10-02 01:48:49 +00001564- Fix segfault with invalid coding.
1565
1566- SF bug #772896: unknown encoding results in MemoryError.
1567
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001568- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001569 supported a __len__() method which evaluated to False when the iterator
1570 was empty.
1571
Guido van Rossum630db602005-09-20 18:49:54 +00001572- On 64-bit platforms, when __len__() returns a value that cannot be
1573 represented as a C int, raise OverflowError.
1574
Skip Montanarof8948ca2005-09-19 03:54:46 +00001575- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001576 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001577
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001578- SF bug #893549: parsing keyword arguments was broken with a few format
1579 codes.
1580
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001581- Changes donated by Elemental Security to make it work on AIX 5.3
1582 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1583 bug #105470: test_pwd fails on 64bit system (Opteron).
1584
Guido van Rossum539c6622005-09-14 17:49:54 +00001585- Changes donated by Elemental Security to make it work on HP-UX 11 on
1586 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1587
Georg Brandl4550b8d2005-08-26 06:43:52 +00001588- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001589 (fixes bug #1119418).
1590
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001591- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1592
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001593- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1594 exceptions that cause a function to exit.
1595
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001596- The implementation of set() and frozenset() was revised to use its
1597 own internal data structure. Memory consumption is reduced by 1/3
1598 and there are modest speed-ups as well. The API is unchanged.
1599
Tim Petersde7990b2005-07-17 23:45:23 +00001600- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1601
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001602- SF bug #1229429: PyObject_CallMethod failed to decrement some
1603 reference counts in some error exit cases.
1604
Tim Petersecc6e6a2005-07-10 22:30:55 +00001605- SF bug #1185883: Python's small-object memory allocator took over
1606 a block managed by the platform C library whenever a realloc specified
1607 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001608 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001609 portable way to copy data from the C-managed block into Python's
1610 small-object space without risking a memory fault. Python's small-object
1611 realloc now leaves such blocks under the control of the platform C
1612 realloc.
1613
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001614- SF bug #1232517: An overflow error was not detected properly when
1615 attempting to convert a large float to an int in os.utime().
1616
Raymond Hettinger3296e692005-06-29 23:29:56 +00001617- SF bug #1224347: hex longs now print with lowercase letters just
1618 like their int counterparts.
1619
Michael W. Hudson188d4362005-06-20 16:52:57 +00001620- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1621 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1622 interpreter states; back out that fix and do a better job (see
1623 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1624 for a longer write-up of the problem).
1625
Michael W. Hudsondf888462005-06-03 14:41:55 +00001626- SF patch #1180995: marshal now uses a binary format by default when
1627 serializing floats.
1628
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001629- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1630 the routines that promise to produce IEEE 754 binary representations
1631 of floats now simply copy bytes around.
1632
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001633- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1634 278.
1635
Brett Cannonc3647ac2005-04-26 03:45:26 +00001636- patch #1109424: int, long, float, complex, and unicode now check for the
1637 proper magic slot for type conversions when subclassed. Previously the
1638 magic slot was ignored during conversion. Semantics now match the way
1639 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001640 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001641 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001642 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001643
Barry Warsawc8d907c2005-04-19 23:43:40 +00001644- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1645 NULL, now raise an AttributeError when attempting to set or delete the
1646 attribute. Previously a TypeError was raised, but this was inconsistent
1647 with the equivalent pure-Python implementation.
1648
Michael W. Hudson774479c2005-04-18 08:46:17 +00001649- It is now safe to call PyGILState_Release() before
1650 PyEval_InitThreads() (note that if there is reason to believe there
1651 are multiple threads around you still must call PyEval_InitThreads()
1652 before using the Python API; this fix is for extension modules that
1653 have no way of knowing if Python is multi-threaded yet).
1654
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001655- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1656 disabled caused a crash.
1657
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001658- Bug #1165306: instancemethod_new allowed the creation of a method
1659 with im_class == im_self == NULL, which caused a crash when called.
1660
Tim Petersecc6e6a2005-07-10 22:30:55 +00001661- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001662 fixes the crash seen in bug #1165761
1663
Raymond Hettinger96229b12005-03-11 06:49:40 +00001664- Added two new builtins, any() and all().
1665
Brett Cannon409d8f22005-03-05 06:47:57 +00001666- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001667 (e.g., ``class C(): pass`` is no longer a syntax error).
1668 Patch #1176012 added support to the 'parser' module and 'compiler' package
1669 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001670
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001671- Patch #1115086: Support PY_LONGLONG in structmember.
1672
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001673- Bug #1155938: new style classes did not check that __init__() was
1674 returning None.
1675
Tim Petersecc6e6a2005-07-10 22:30:55 +00001676- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001677 ('\') with a specific error message.
1678
Martin v. Löwisff232d72005-03-03 09:24:38 +00001679- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1680
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001681- Bug #1124295: the __name__ attribute of file objects was
1682 inadvertently made inaccessible in restricted mode.
1683
Tim Petersecc6e6a2005-07-10 22:30:55 +00001684- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001685 an ferror() call.
1686
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001687- min() and max() now support key= arguments with the same meaning as in
1688 list.sort().
1689
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001690- The peephole optimizer now performs simple constant folding in expressions:
1691 (2+3) --> (5).
1692
Raymond Hettingera422c342005-01-11 03:03:27 +00001693- set and frozenset objects can now be marshalled. SF #1098985.
1694
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001695- Bug #1077106: Poor argument checking could cause memory corruption
1696 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001697
Jeremy Hyltonab630502005-02-04 18:44:06 +00001698- The parser did not complain about future statements in illegal
1699 positions. It once again reports a syntax error if a future
1700 statement occurs after anything other than a doc string.
1701
Neil Schemenauercf52c072005-08-12 17:34:58 +00001702- Change the %s format specifier for str objects so that it returns a
1703 unicode instance if the argument is not an instance of basestring and
1704 calling __str__ on the argument returns a unicode instance.
1705
Tim Petersf4e69282006-02-27 17:15:31 +00001706- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1707 current thread state when the auto-GIL-state machinery knows about
1708 it (since the thread state is being deleted, continuing to remember it
1709 can't help, but can hurt if another thread happens to get created with
1710 the same thread id).
1711
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001712Extension Modules
1713-----------------
1714
Georg Brandl43f08a82006-03-31 18:01:16 +00001715- Patch #1380952: fix SSL objects timing out on consecutive read()s
1716

1718
Anthony Baxterfa869072006-03-20 05:21:58 +00001719- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1720 In addition, the existing ulaw code was updated.
1721
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001722- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001723 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001724
Neal Norwitz10be10c2006-03-16 06:50:13 +00001725- Everything under lib-old was removed. This includes the following modules:
1726 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001727 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001728 util, whatsound, whrandom, zmod
1729
1730- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1731
1732- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001733 is deprecated. The undocumented re.engine variable no longer exists.
1734
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001735- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1736 SS2 (single-shift 2) escape sequences correctly.
1737
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001738- The unicodedata module was updated to the 4.1 version of the Unicode
1739 database. The 3.2 version is still available as unicodedata.db_3_2_0
1740 for applications that require this specific version (such as IDNA).
1741
Neal Norwitzb62c4332006-03-04 18:35:47 +00001742- The timing module is no longer built by default. It was deprecated
1743 in PEP 4 in Python 2.0 or earlier.
1744
Guido van Rossum1968ad32006-02-25 22:38:04 +00001745- Patch 1433928: Added a new type, defaultdict, to the collections module.
1746 This uses the new __missing__ hook behavior added to dict (see above).
1747
Georg Brandldbd83392006-02-20 09:42:33 +00001748- Bug #854823: socketmodule now builds on Sun platforms even when
1749 INET_ADDRSTRLEN is not defined.
1750
Georg Brandlf4f44152006-02-18 22:29:33 +00001751- Patch #1393157: os.startfile() now has an optional argument to specify
1752 a "command verb" to invoke on the file.
1753
Neal Norwitz082b2df2006-02-07 07:04:46 +00001754- Bug #876637, prevent stack corruption when socket descriptor
1755 is larger than FD_SETSIZE.
1756
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001757- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1758 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1759 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1760
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001761- Patch #1422385: The nis module now supports access to domains other
1762 than the system default domain.
1763
Martin v. Löwis14694662006-02-03 12:54:16 +00001764- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1765 are reported, the limit on path name lengths is removed, and stat reports
1766 WindowsError now (instead of OSError).
1767
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001768- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1769
Neal Norwitz62a21122006-01-25 05:21:55 +00001770- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1771 before the env.
1772
Martin v. Löwis11017b12006-01-14 18:12:57 +00001773- Patch #1103116: Basic AF_NETLINK support.
1774

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001902- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1903 been renamed to have only a single underscore prefix. This was done to
1904 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001905
Nick Coghlan43832302006-04-23 17:04:07 +00001906- PEP 338: new module runpy defines a run_module function to support
1907 executing modules which provide access to source code or a code object
1908 via the PEP 302 import mechanisms.
1909
Anthony Baxter93f5b932006-04-03 08:05:07 +00001910- The email module's parsedate_tz function now sets the daylight savings

1918 in attribute values.
1919
Anthony Baxterc51ee692006-04-01 00:57:31 +00001920- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001921 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001922 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001923 module will not be built.
1924
Tim Petersc17976e2006-04-01 00:26:53 +00001925- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1926 aren't officially supported here, and trying to use them will probably
1927 raise an exception some day. But dicts have been allowed, and "mostly
1928 worked", so support for them won't go away without warning.
1929
Georg Brandl338ef7d2006-03-31 18:42:16 +00001930- Bug #1445068: getpass.getpass() can now be given an explicit stream

1948
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001949- email 4.0 package now integrated. This is largely the same as the email 3.0
1950 package that was included in Python 2.3, except that PEP 8 module names are
1951 now used (e.g. mail.message instead of email.Message). The MIME classes
1952 have been moved to a subpackage (e.g. email.mime.text instead of
1953 email.MIMEText). The old names are still supported for now. Several
1954 deprecated Message methods have been removed and lots of bugs have been
1955 fixed. More details can be found in the email package documentation.
1956
Walter Dörwald40108c92006-03-27 08:15:44 +00001957- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1958 (a subclass of tuple) that provides incremental decoders and encoders
1959 (a way to use stateful codecs without the stream API). Python functions
1960 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1961 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1962 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001964- Patch #1359365: Calling next() on a closed StringIO.String object raises
1965 a ValueError instead of a StopIteration now (like file and cString.String do).
1966 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1967 called before (like file and StringIO.StringIO do).

Brett Cannon3cbd0382005-12-16 22:49:23 +00002040- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002041 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2042 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2043 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2044 Ronald L. Rivest offered this advice for Python:
2045
2046 "The consensus of researchers in this area (at least as
2047 expressed at the NIST Hash Function Workshop 10/31/05),
2048 is that SHA-256 is a good choice for the time being, but
2049 that research should continue, and other alternatives may
2050 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002051

2105 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002106 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002107

2145 Bug #1224621.
2146
Raymond Hettinger68c04532005-06-10 11:05:19 +00002147- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002148 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002149 the generate_tokens() function now accepts a callable argument that
2150 terminates by raising StopIteration.
2151
Georg Brandl9166e1a2005-06-04 09:20:03 +00002152- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2160 class at all.
2161
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002162- distutils.commands.upload was added to support uploading distribution

2166 them to PyPI.
2167
Raymond Hettinger267b8682005-03-27 10:47:39 +00002168- decimal operator and comparison methods now return NotImplemented
2169 instead of raising a TypeError when interacting with other types. This
2170 allows other classes to implement __radd__ style methods and have them
2171 work as expected.
2172
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002173- Bug #1163325: Decimal infinities failed to hash. Attempting to
2174 hash a NaN raised an InvalidOperation instead of a TypeError.
2175
Tim Petersecc6e6a2005-07-10 22:30:55 +00002176- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2210
Guido van Rossumd0641422005-02-03 15:01:24 +00002211- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2212 disables recursive traversal through instance attributes, which can
2213 be exploited in various ways.
2214
Tim Peterse3547fd2005-12-16 23:13:57 +00002215- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002216 flags on the HTTP listening socket.
2217
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002218- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2219 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2220

2227
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002228- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2229
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002230- Enhancements to the csv module:
2231
2232 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002233 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002234 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002235 + Dialect parameter parsing has been re-implemented to improve error
2236 reporting.
2237 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2238 dictates.
2239 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002240 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002241 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002242 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2243 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002244 + reader now allows \r characters to be quoted (previously it only allowed
2245 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002246 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002247 + Dialect classes passed to the module are no longer instantiated by
2248 the module before being parsed (the former validation scheme required
2249 this, but the mechanism was unreliable).
2250 + The dialect registry now contains instances of the internal
2251 C-coded dialect type, rather than references to python objects.
2252 + the internal c-coded dialect type is now immutable.
2253 + register_dialect now accepts the same keyword dialect specifications
2254 as the reader and writer, allowing the user to register dialects
2255 without first creating a dialect class.
2256 + a configurable limit to the size of parsed fields has been added -
2257 previously, an unmatched quote character could result in the entire
2258 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002259 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002260 the parser field size limit (returning the former limit). The initial
2261 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002262 + A line_num attribute has been added to the reader object, which tracks
2263 the number of lines read from the source iterator. This is not
2264 the same as the number of records returned, as records can span
2265 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002266 + reader and writer objects were not being registered with the cyclic-GC.
2267 This has been fixed.
2268
Brett Cannone6539c42005-01-08 02:43:53 +00002269- _DummyThread objects in the threading module now delete self.__block that is
2270 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2271 lock primitives tend to be limited in number and thus should not be wasted on
2272 a _DummyThread object. Fixes bug #1089632.
2273
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002274- The imghdr module now detects Exif files.
2275
Raymond Hettinger6065d322004-12-20 23:51:53 +00002276- StringIO.truncate() now correctly adjusts the size attribute.
2277 (Bug #951915).
2278
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002279- locale.py now uses an updated locale alias table (built using
2280 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2281 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002282 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002283
Raymond Hettinger3557f422004-12-07 12:02:02 +00002284- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2285
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002286- the pickle module no longer accepts the deprecated None option in the
2287 args tuple returned by __reduce__().
2288
Brett Cannon84667c02004-12-07 03:25:18 +00002289- optparse now optionally imports gettext. This allows its use in setup.py.
2290
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002291- the pickle module no longer uses the deprecated bin parameter.
2292
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002293- the shelve module no longer uses the deprecated binary parameter.
2294
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002295- the pstats module no longer uses the deprecated ignore() method.
2296
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002297- the filecmp module no longer uses the deprecated use_statcache argument.
2298
Raymond Hettinger664347b2004-12-04 21:21:53 +00002299- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2300 extended or overridden by subclasses. Formerly, the subclassed method would
2301 be ignored by the rest of the module. (Bug #1078905).
2302
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002303- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002304 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002305
Walter Dörwald36733692004-12-22 12:50:50 +00002306- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2307 once when a size argument is given. This prevents a buffer overflow in the
2308 tokenizer with very long source lines.
2309
Barry Warsaw538561e2006-01-01 21:48:54 +00002310- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2311 immediately after creating the object, without any intervening
2312 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002313
Skip Montanaro05885812005-01-16 20:48:27 +00002314- The reconvert.quote function can now emit triple-quoted strings. The
2315 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002316
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002317- ``UserString.MutableString`` now supports negative indices in
2318 ``__setitem__`` and ``__delitem__``
2319
Greg Ward40407942005-03-05 02:53:17 +00002320- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2321 correctly.
2322
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002323- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2324 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2325 character even if the user has passed a size parameter to get a proper
2326 line ending. Remove the special handling of a "\r\n" that has been split
2327 between two lines.
2328
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002329- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2330 about illegal code points. The codec now supports PEP 293 style error
2331 handlers.
2332
Walter Dörwald78a78b02005-09-01 12:04:29 +00002333- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002334 from the input stream, so that the output is a byte string in the correct
2335 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002336
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002337- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2338 considering it exactly like a '*'.
2339
Walter Dörwald007f8df2005-10-09 19:42:27 +00002340- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2341 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002342
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002343- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2344
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002345- Patch #1413711: Certain patterns of differences were making difflib
2346 touch the recursion limit.
2347
Walter Dörwald58917a62006-03-31 15:26:22 +00002348- Bug #947906: An object oriented interface has been added to the calendar
2349 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002350 called as a script (e.g. via ``python -mcalendar``). Localized month and
2351 weekday names can be ouput (even if an exotic encoding is used) using
2352 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002353
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002354Build
2355-----
2356
Neal Norwitz602d3392006-03-31 08:21:40 +00002357- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2358 by using -mieee gcc option.
2359
Martin v. Löwis86d66262006-02-17 08:40:11 +00002360- Patch #1432345: Make python compile on DragonFly.
2361
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002362- Build support for Win64-AMD64 was added.
2363
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002364- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2365
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002366- Patch #881820: look for openpty and forkpty also in libbsd.
2367
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002368- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2369 The zlib module is now builtin on Windows.
2370
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002371- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2372
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002373- Bug #1189330: configure did not correctly determine the necessary
2374 value of LINKCC if python was built with GCC 4.0.
2375
Trent Mick8321b422005-07-26 02:29:21 +00002376- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2377 vulnerability in zlib 1.2.1 and 1.2.2.
2378
Brett Cannon08cd5982005-04-24 22:26:38 +00002379- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2380 flags that change binary compatibility. Changes were also made to
2381 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002382 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002383
Bob Ippolitoed233462005-03-29 13:47:59 +00002384- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2385 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2386 no longer exists). This configure patch makes things right.
2387
Martin v. Löwise2713be2005-03-08 15:03:08 +00002388- Bug #1158607: Build with --disable-unicode again.
2389
Brett Cannon46d96232005-02-16 00:07:19 +00002390- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2391 defined. Discovered as a result of not being able to build on OS X.
2392
Brett Cannon516592f2004-12-07 00:42:59 +00002393- setup.py now uses the directories specified in LDFLAGS using the -L option
2394 and in CPPFLAGS using the -I option for adding library and include
2395 directories, respectively, for compiling extension modules against. This has
2396 led to the core being compiled using the values in CPPFLAGS. It also removes
2397 the need for the special-casing of both DarwinPorts and Fink for darwin since
2398 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2399 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2400 Fink, ``-I/opt/local/include`` for DarwinPorts).
2401
Brett Cannon43802422005-02-10 20:48:03 +00002402- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2403 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2404 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2405 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002407C API
2408-----
2409
Tim Petersc9d78aa2006-03-26 23:27:58 +00002410- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2411 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2412 is obtained via the ``PyObject_`` family, it must be released via the
2413 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2414 always been officially true, but when Python's small-object allocator was
2415 introduced, an attempt was made to cater to a few extension modules
2416 discovered at the time that obtained memory via ``PyObject_New`` but
2417 released it via ``PyMem_DEL``. It's years later, and if such code still
2418 exists it will fail now (probably with segfaults, but calling wrong
2419 low-level memory management functions can yield many symptoms).
2420
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002421- Added a C API for set and frozenset objects.
2422
Raymond Hettinger66517482004-12-03 11:45:13 +00002423- Removed PyRange_New().
2424
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002425- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2426 mapping argument now. This string is used as a mapping table. Byte values
2427 greater than the length of the string and 0xFFFE are treated as undefined
2428 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002434- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002435
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002436- Patch #1276356: New resource "urlfetch" is implemented. This enables
2437 even impatient people to run tests that require remote files.
