Neal Norwitzff4b63b2006-08-04 04:50:21 +0000362
363Core and builtins
364-----------------
365
Neal Norwitz24b6f202006-09-05 04:43:56 +0000366- Fix infinite recursion when subclassing long and overriding __hash__.
367
368- Fix concatenation (+=) of long strings.
369
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000370- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000371 compared equal or unequal to a string and a UnicodeDecodeError
372 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000373
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000374 Instead, the equal (==) and unequal (!=) comparison operators will
375 now issue a UnicodeWarning and interpret the two objects as
376 unequal. The UnicodeWarning can be filtered as desired using
377 the warning framework, e.g. silenced completely, turned into an
378 exception, logged, etc.
379
380 Note that compare operators other than equal and unequal will still
381 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000382
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000383- Fix segfault when doing string formatting on subclasses of long.
384
385- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
386 with new-style classes.
387
388- Fix bug related to __len__ functions returning negative values with
389 classic classes.
390
391- Patch #1538606, Fix __index__() clipping. There were some problems
392 discovered with the API and how integers that didn't fit into Py_ssize_t
393 were handled. This patch attempts to provide enough alternatives
394 to effectively use __index__.
395
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000396- Bug #1536021: __hash__ may now return long int; the final hash
397 value is obtained by invoking hash on the long int.
398
Thomas Hellerab1049c2006-08-08 17:37:00 +0000399- Bug #1536786: buffer comparison could emit a RuntimeWarning.
400
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000401- Bug #1535165: fixed a segfault in input() and raw_input() when
402 sys.stdin is closed.
403
Thomas Heller74d36f02006-08-04 18:17:40 +0000404- On Windows, the PyErr_Warn function is now exported from
405 the Python dll again.
406
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000407- Bug #1191458: tracing over for loops now produces a line event
408 on each iteration. Fixing this problem required changing the .pyc
409 magic number. This means that .pyc files generated before 2.5c1
410 will be regenerated.
411
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000412- Bug #1333982: string/number constants were inappropriately stored
413 in the byte code and co_consts even if they were not used, ie
414 immediately popped off the stack.
415
Georg Brandle9462c72006-08-04 18:03:37 +0000416- Fixed a reference-counting problem in property().
417
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000418
419Library
420-------
421
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000422- Fix a bug in the ``compiler`` package that caused invalid code to be
423 generated for generator expressions.
424
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000425- The distutils version has been changed to 2.5.0. The change to
426 keep it programmatically in sync with the Python version running
427 the code (introduced in 2.5b3) has been reverted. It will continue
428 to be maintained manually as static string literal.
429
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000430- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000431 and this cannot be converted to the required C type, an exception is
432 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000433 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000434
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000435- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000436 an exception.
437
Tim Peterscbdd3502006-09-05 01:47:53 +0000438- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000439 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000440 workarounds for clocks with low resolution, to stop the code yielding
441 duplicate UUIDs.
442
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000443- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
444 before raising SystemExit, allowing IDLE to honor quit() and exit().
445
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000446- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
447
Georg Brandl7a1af772006-08-14 21:55:28 +0000448- Patch #1536071: trace.py should now find the full module name of a
449 file correctly even on Windows.
450
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000451- logging's atexit hook now runs even if the rest of the module has
452 already been cleaned up.
453
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000454- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000455
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000456- Bug #1531405, format_exception no longer raises an exception if
457 str(exception) raised an exception.
458
Neil Schemenauer06ded092006-08-04 16:20:30 +0000459- Fix a bug in the ``compiler`` package that caused invalid code to be
460 generated for nested functions.

467
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000468- Patch #1511317: don't crash on invalid hostname (alias) info.
469
Georg Brandl3335a7a2006-08-14 21:42:55 +0000470- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
471 raises the correct exceptions.
472
Thomas Heller1ce433e2006-08-14 16:20:04 +0000473- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
474 '-no-stack-protector' compiler flag for OpenBSD has been removed.
475
Thomas Heller86720042006-08-14 11:17:48 +0000476- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
477 uses the _as_parameter_ attribute when objects are passed to foreign
478 function calls. The ctypes version number was changed to 1.0.1.
479
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000480- Bug #1530559, struct.pack raises TypeError where it used to convert.
481 Passing float arguments to struct.pack when integers are expected
482 now triggers a DeprecationWarning.
483
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000484

520
Tim Peters4643c2f2006-08-10 22:45:34 +0000521- Bug #1069160. Internal correctness changes were made to
522 ``PyThreadState_SetAsyncExc()``. A test case was added, and
523 the documentation was changed to state that the return value
524 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +0000531
532Core and builtins
533-----------------
534
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000535- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000536 returned a long (see PEP 353).
537
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000538- Bug #1515471: string.replace() accepts character buffers again.
539
Neal Norwitz07aadb12006-07-30 06:55:48 +0000540- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
541 This provides the proper warning for struct.pack().
542 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
543
Neal Norwitz0d62a062006-07-30 06:53:31 +0000544- Patch #1531113: Fix augmented assignment with yield expressions.
545 Also fix a SystemError when trying to assign to yield expressions.
546
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000547- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
548 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
549 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
550 excessive filesystem operations during imports.
551
Tim Petersbc24eee2006-07-27 01:14:53 +0000552- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
553 operations on signed longs that are formally undefined by C.
554 Unfortunately, at least one compiler now cares about that, so complicated
555 the code to make that compiler happy again.
556
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000557- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
558
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000559- Patch #1232023: Stop including current directory in search
560 path on Windows.
561
Neal Norwitze1fdb322006-07-21 05:32:28 +0000562- Fix some potential crashes found with failmalloc.
563
Neal Norwitze7563102006-07-17 01:00:16 +0000564- Fix warnings reported by Klocwork's static analysis tool.
565
Neal Norwitz84be93b2006-07-16 01:50:38 +0000566- Bug #1512814, Fix incorrect lineno's when code within a function
567 had more than 255 blank lines.
568
Georg Brandl9dceedb2006-07-12 15:31:17 +0000569- Patch #1521179: Python now accepts the standard options ``--help`` and
570 ``--version`` as well as ``/?`` on Windows.
571
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000572- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000573 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000574 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000575
Tim Peters112aad32006-07-19 00:03:19 +0000576- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000577 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000578 new ``sys._current_frames()`` returns a dictionary with one entry,
579 mapping the faux "thread id" 0 to the current frame.
580
Ronald Oussoren3075e162006-07-25 20:28:55 +0000581- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000582
Ronald Oussoren3075e162006-07-25 20:28:55 +0000583
Neal Norwitza1f10902006-07-12 07:28:29 +0000584Library
585-------
586
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000587- Correction of patch #1455898: In the mbcs decoder, set final=False
588 for stream decoder, but final=True for the decode function.
589
Georg Brandl07fec3a2006-08-01 18:49:24 +0000590- os.urandom no longer masks unrelated exceptions like SystemExit or
591 KeyboardInterrupt.
592
Tim Peters4643c2f2006-08-10 22:45:34 +0000593- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000594 shutil.copytree on Windows
595
Georg Brandle34ac7c2006-07-30 11:07:23 +0000596- Bug #1002398: The documentation for os.path.sameopenfile now correctly
597 refers to file descriptors, not file objects.
598
Tim Peterscbdd3502006-09-05 01:47:53 +0000599- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000600 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000601 #1513611, and probably others.
602
Georg Brandledd9b0d2006-07-29 09:33:26 +0000603- Bug #1441397: The compiler module now recognizes module and function
604 docstrings correctly as it did in Python 2.4.
605
Tim Peters6f681472006-07-27 23:44:37 +0000606- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
607 lost that tests are sorted by name before being run. This rarely
608 matters for well-written tests, but can create baffling symptoms if
609 side effects from one test to the next affect outcomes. ``DocTestFinder``
610 has been changed to sort the list of tests it returns.
611
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000612- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000613 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000614
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000615- Bug #978833: Really close underlying socket in _socketobject.close.
616
Georg Brandldb232dc2006-08-20 13:15:43 +0000617- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
618 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000619
Georg Brandlcf0c1722006-07-26 07:23:32 +0000620- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
621 to recursive calls and call it with the failing package name.
622
Martin v. Löwis0b483032006-07-25 09:53:12 +0000623- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
624
Georg Brandlc13c34c2006-07-24 14:09:56 +0000625- Patch #1515343: Fix printing of deprecated string exceptions with a
626 value in the traceback module.
627
Greg Ward48fae7a2006-07-23 16:05:51 +0000628- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
629
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000630- Patch #1524429: Use repr() instead of backticks in Tkinter again.
631
Brett Cannoncaebe222006-07-18 04:41:36 +0000632- Bug #1520914: Change time.strftime() to accept a zero for any position in its
633 argument tuple. For arguments where zero is illegal, the value is forced to
634 the minimum value that is correct. This is to support an undocumented but
635 common way people used to fill in inconsequential information in the time
636 tuple pre-2.4.
637
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000638- Patch #1220874: Update the binhex module for Mach-O.
639
Barry Warsawb110bad2006-07-21 14:51:07 +0000640- The email package has improved RFC 2231 support, specifically for
641 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
642 (name*0=<blah>) parameter continuations. This may change the types of
643 values returned from email.message.Message.get_param() and friends.
644 Specifically in some cases where non-encoded continuations were used,
645 get_param() used to return a 3-tuple of (None, None, string) whereas now it
646 will just return the string (since non-encoded continuations don't have
647 charset and language parts).
648
649 Also, whereas % values were decoded in all parameter continuations, they are
650 now only decoded in encoded parameter parts.
651
Ronald Oussoren3075e162006-07-25 20:28:55 +0000652- Bug #1517990: IDLE keybindings on MacOS X now work correctly
653
654- Bug #1517996: IDLE now longer shows the default Tk menu when a
655 path browser, class browser or debugger is the frontmost window on MacOS X
656
Barry Warsaw00decd72006-07-27 23:43:15 +0000657- Patch #1520294: Support for getset and member descriptors in types.py,
658 inspect.py, and pydoc.py. Specifically, this allows for querying the type
659 of an object against these built-in types and more importantly, for getting
660 their docstrings printed in the interactive interpreter's help() function.

667 a socket operation on a socket with a timeout, the exception will be
668 caught correctly. Previously, the exception was not caught.
669
Thomas Heller1393d6a2006-07-28 21:43:20 +0000670- Patch #1529514: The _ctypes extension is now compiled on more
671 openbsd target platforms.
672
Tim Peters9cab5932006-07-28 00:30:00 +0000673- The ``__reduce__()`` method of the new ``collections.defaultdict`` had

Thomas Hellerce049a02006-07-14 17:51:14 +0000681- Patch #1521817: Index range checking on ctypes arrays containing
682 exactly one element enabled again. This allows iterating over these
683 arrays, without the need to check the array size before.
684
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000685- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000686 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000687 /dev/null in certain cases; this is now fixed.
688
Thomas Heller47d7a062006-07-12 08:43:47 +0000689- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
690 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000691
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000692- Because of a misspelled preprocessor symbol, ctypes was always
693 compiled without thread support; this is now fixed.
694
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000695- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
696 methods now allow their database parameter to be None as the
697 sleepycat API allows.
698
Matt Flemingec926502006-07-28 11:27:27 +0000699- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
700 bluetooth API compared with Linux and FreeBSD.

703-----
704
705- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
706 how long the test file should take to play. Now accepts taking 2.93 secs
707 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
708
Georg Brandl4793aa32006-07-28 18:31:39 +0000709- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
710 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
711 run via ``regrtest.py``. Now they do.

720
721- PythonLauncher now works correctly when the path to the script contains
722 characters that are treated specially by the shell (such as quotes).
723
724- Bug #1527397: PythonLauncher now launches scripts with the working directory
725 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000726 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000727 expect.

736-----------------
737
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000738- Bug #1441486: The literal representation of -(sys.maxint - 1)
739 again evaluates to a int object, not a long.
740
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000741- Bug #1501934: The scope of global variables that are locally assigned
742 using augmented assignment is now correctly determined.
743
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000744- Bug #927248: Recursive method-wrapper objects can now safely
745 be released.
746
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000747- Bug #1417699: Reject locale-specific decimal point in float()
748 and atof().
749
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000750- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
751 omit a default "error" argument for NULL pointer. This allows
752 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000753
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000754- Bug #1519018: 'as' is now validated properly in import statements.
755
Neal Norwitz28746ab2006-07-09 22:14:42 +0000756- On 64 bit systems, int literals that use less than 64 bits are
757 now ints rather than longs.
758
Neal Norwitzed657552006-07-10 00:04:44 +0000759- Bug #1512814, Fix incorrect lineno's when code at module scope
760 started after line 256.
761
Tim Peters32a83612006-07-10 21:08:24 +0000762- New function ``sys._current_frames()`` returns a dict mapping thread
763 id to topmost thread stack frame. This is for expert use, and is
764 especially useful for debugging application deadlocks. The functionality
765 was previously available in Fazal Majid's ``threadframe`` extension
766 module, but it wasn't possible to do this in a wholly threadsafe way from
767 an extension.

814
Brett Cannon53ab5b72006-06-22 16:49:14 +0000815- Bug #1510580: The 'warnings' module improperly required that a Warning
816 category be either a types.ClassType and a subclass of Warning. The proper
817 check is just that it is a subclass with Warning as the documentation states.
818
Georg Brandlad29e632006-06-21 17:45:17 +0000819- The compiler module now correctly compiles the new try-except-finally
820 statement (bug #1509132).
821
Neal Norwitz60373cd2006-06-22 06:30:50 +0000822- The wsgiref package is now installed properly on Unix.
823
Vinay Sajip28e57612006-07-01 10:45:20 +0000824- A bug was fixed in logging.config.fileConfig() which caused a crash on
825 shutdown when fileConfig() was called multiple times.
826
Gerhard Häring762fbd32006-07-02 17:48:30 +0000827- The sqlite3 module did cut off data from the SQLite database at the first

Tim Peters112aad32006-07-19 00:03:19 +0000834- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
835 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
836 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000837
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000838- Assigning None to pointer type fields in ctypes structures possible
839 overwrote the wrong fields, this is fixed now.
840
841- Fixed a segfault in _ctypes when ctypes.wintypes were imported
842 on non-Windows platforms.
843
844- Bug #1518190: The ctypes.c_void_p constructor now accepts any
845 integer or long, without range checking.
846
847- Patch #1517790: It is now possible to use custom objects in the ctypes
848 foreign function argtypes sequence as long as they provide a from_param
849 method, no longer is it required that the object is a ctypes type.
850
851- The '_ctypes' extension module now works when Python is configured
852 with the --without-threads option.

869
Tim Peters32a83612006-07-10 21:08:24 +0000870- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000871 Previously, the slight difference could cause compilation errors of the
872 'zlib' module on systems with more than one version of zlib.
873
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000874- The MSI compileall step was fixed to also support a TARGETDIR

Vinay Sajip28e57612006-07-01 10:45:20 +0000918 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000919
Brett Cannon22565aa2006-06-09 22:31:23 +0000920- Bug #532646: object.__call__() will continue looking for the __call__
921 attribute on objects until one without one is found. This leads to recursion
922 when you take a class and set its __call__ attribute to an instance of the
923 class. Originally fixed for classic classes, but this fix is for new-style.
924 Removes the infinite_rec_3 crasher.
925
Georg Brandl24250812006-06-09 18:45:48 +0000926- The string and unicode methods startswith() and endswith() now accept
927 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
928
Brett Cannonde3b0522006-06-08 17:00:45 +0000929- Buffer objects, at the C level, never used the char buffer
930 implementation even when the char buffer for the wrapped object was
931 explicitly requested (originally returned the read or write buffer).
932 Now a TypeError is raised if the char buffer is not present but is
933 requested.
934
Georg Brandlddbaa662006-06-04 21:56:52 +0000935- Patch #1346214: Statements like "if 0: suite" are now again optimized
936 away like they were in Python 2.4.
937
Georg Brandlb7c8f542006-05-27 12:30:25 +0000938- Builtin exceptions are now full-blown new-style classes instead of
939 instances pretending to be classes, which speeds up exception handling
940 by about 80% in comparison to 2.5a2.
941
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000942- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
943 Unicode 4.1.
944
Georg Brandlf4ef1162006-05-26 18:03:31 +0000945- Patch #921466: sys.path_importer_cache is now used to cache valid and
946 invalid file paths for the built-in import machinery which leads to
947 fewer open calls on startup.
948
Tim Peters696cf432006-05-24 21:10:40 +0000949- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
950 of-2 bases. The largest speedup is for inputs with about 1000 decimal
951 digits. Conversion from non-power-of-2 bases remains quadratic-time in
952 the number of input digits (it was and remains linear-time for bases
953 2, 4, 8, 16 and 32).
954
Tim Petersb713ec22006-05-23 18:45:30 +0000955- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
956 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
957 an integer close to ``sys.maxint``. This was repaired by patch
958 #1335972, which also gives a nice speedup.
959
Richard Jonescebbefc2006-05-23 18:28:17 +0000960- Patch #1337051: reduced size of frame objects.
961
962- PyErr_NewException now accepts a tuple of base classes as its
963 "base" parameter.
964
Richard Jones7c88dcc2006-05-23 10:37:38 +0000965- Patch #876206: function call speedup by retaining allocated frame
966 objects.
967
Georg Brandl7b90e162006-05-18 07:01:27 +0000968- Bug #1462152: file() now checks more thoroughly for invalid mode
969 strings and removes a possible "U" before passing the mode to the
970 C library function.
971
Neal Norwitz1004a532006-05-15 07:17:23 +0000972- Patch #1488312, Fix memory alignment problem on SPARC in unicode
973
Neal Norwitz373f0a72006-05-15 07:04:36 +0000974- Bug #1487966: Fix SystemError with conditional expression in assignment
975
Martin v. Löwis879768d2006-05-11 13:28:43 +0000976- WindowsError now has two error code attributes: errno, which carries
977 the error values from errno.h, and winerror, which carries the error
978 values from winerror.h. Previous versions put the winerror.h values
979 (from GetLastError()) into the errno attribute.
980
Martin v. Löwis77736712006-05-04 05:51:03 +0000981- Patch #1475845: Raise IndentationError for unexpected indent.
982
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000983- Patch #1479181: split open() and file() from being aliases for each other.
984
Tim Peters44bd9862006-06-01 13:49:23 +0000985- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
986 methods were always silently ignored by dictionaries when comparing keys.
987 They are now passed through (except when using the C API function
988 ``PyDict_GetItem()``, whose semantics did not change).
989
990- Bug #1456209: In some obscure cases it was possible for a class with a
991 custom ``__eq__()`` method to confuse dict internals when class instances
992 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
993 No, you don't have any code that did this ;-)

996-----------------
997
Trent Mick960a3f82006-06-28 20:30:41 +0000998- Bug #1295808: expat symbols should be namespaced in pyexpat
999
1000- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1001
Brett Cannon6ee7d012006-06-08 16:23:04 +00001002- Change binascii.hexlify to accept a read-only buffer instead of only a char
1003 buffer and actually follow its documentation.
1004
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001005- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1006
Nick Coghlanc649ec52006-05-29 12:43:05 +00001007- Patch #1478788 (modified version): The functional extension module has
1008 been renamed to _functools and a functools Python wrapper module added.
1009 This provides a home for additional function related utilities that are
1010 not specifically about functional programming. See PEP 309.
1011
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001012- Patch #1493701: performance enhancements for struct module.
1013
Georg Brandl378d5922006-05-17 14:26:50 +00001014- Patch #1490224: time.altzone is now set correctly on Cygwin.
1015
Georg Brandl8d3342b2006-05-16 07:38:27 +00001016- Patch #1435422: zlib's compress and decompress objects now have a
1017 copy() method.
1018
Andrew MacIntyre92913322006-06-13 15:04:24 +00001019- Patch #1454481: thread stack size is now tunable at runtime for thread
1020 enabled builds on Windows and systems with Posix threads support.
1021
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001022- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1023 (up to the system limit of 32K characters).
1024
1025- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1026 As a result, these functions now raise WindowsError instead of OSError.
1027
Tim Peters7a822da2006-05-25 21:50:17 +00001028- ``time.clock()`` on Win64 should use the high-performance Windows
1029 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1030 Windows platforms).
1031
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001032- Calling Tk_Init twice is refused if the first call failed as that
1033 may deadlock.
1034
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001035- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1036 accept it without potentially using an uninitialized pointer.
1037
1038- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1039 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1040 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001041
Gregory P. Smith372b5832006-06-05 18:48:21 +00001042- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001043 [pybsddb project SF patch number 1466734]
1044
Gregory P. Smith372b5832006-06-05 18:48:21 +00001045- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1046 parameter is supplied. [SF pybsddb bug #1477863]
1047
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001048- bsddb: the __len__ method of a DB object has been fixed to return correct
1049 results. It could previously incorrectly return 0 in some cases.
1050 Fixes SF bug 1493322 (pybsddb bug 1184012).
1051
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001052- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1053 aborts the db transaction safely when a modifier callback fails.
1054 Fixes SF python patch/bug #1408584.
1055
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001056- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001057 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001058 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1059 database calls that would previously deadlock. [SF python bug #775414]
1060
Vinay Sajip28e57612006-07-01 10:45:20 +00001061- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001062
Walter Dörwald4994d952006-06-19 08:07:50 +00001063- Patch #1506645: add Python wrappers for the curses functions
1064 is_term_resized, resize_term and resizeterm.

1068
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001069- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1070 functions.
1071
Martin v. Löwis3798da02006-06-17 18:44:27 +00001072- Patch #812986: Update turtle output even if not tracing.
1073
Vinay Sajip28e57612006-07-01 10:45:20 +00001074- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001075 Tkinter.BaseWidget.
1076
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001077- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1078
Martin v. Löwis337487e2006-06-17 09:15:14 +00001079- Patch #763580: Add name and value arguments to Tkinter variable
1080 classes.
1081
Georg Brandl83cc0d02006-06-14 08:50:03 +00001082- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1083 mime.types file for determining MIME types.
1084
Georg Brandl2605ca82006-06-14 06:08:31 +00001085- Bug #1339007: Shelf objects now don't raise an exception in their
1086 __del__ method when initialization failed.
1087
Martin v. Löwisd8251432006-06-14 05:21:04 +00001088- Patch #1455898: The MBCS codec now supports the incremental mode for
1089 double-byte encodings.
1090
Tim Peters43898b42006-06-14 04:09:25 +00001091- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1092 guarantee that adjacent triples in the return list always describe
1093 non-adjacent blocks. Previously, a pair of matching blocks could end
1094 up being described by multiple adjacent triples that formed a partition
1095 of the matching pair.
1096
Greg Ward0e0c9f42006-06-11 16:24:11 +00001097- Bug #1498146: fix optparse to handle Unicode strings in option help,
1098 description, and epilog.
1099
Greg Wardd1c797e2006-06-11 14:42:41 +00001100- Bug #1366250: minor optparse documentation error.
1101
Greg Ward7f547402006-06-11 00:40:49 +00001102- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1103 clarify docs.
1104
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001105- The wsgiref package has been added to the standard library.
1106
Nick Coghlan676725d2006-06-08 13:54:49 +00001107- The functions update_wrapper() and wraps() have been added to the functools
1108 module. These make it easier to copy relevant metadata from the original
1109 function when writing wrapper functions.
1110
Tim Petersd6a9eef2006-06-05 01:48:21 +00001111- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1112 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001113
Martin v. Löwis3f767792006-06-04 19:36:28 +00001114- Patch #1359618: Speed up charmap encoder by using a trie structure
1115 for lookup.
1116
Tim Petersd609b1a2006-06-02 23:22:51 +00001117- The functions in the ``pprint`` module now sort dictionaries by key
1118 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1119 if and only if its display required more than one line, although that
1120 wasn't documented. The new behavior increases predictability; e.g.,
1121 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1122
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001123- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1124 (thanks for J. J. Lee).
1125
Georg Brandl2b330372006-05-28 20:23:12 +00001126- Patch #1496206: improve urllib2 handling of passwords with respect to
1127 default HTTP and HTTPS ports.
1128
George Yoshidaf3c65de2006-05-28 16:39:09 +00001129- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1130
Bob Ippolito7298f272006-05-23 18:43:47 +00001131- Patch #1281707: speed up gzip.readline.
1132
Georg Brandlb89316f2006-05-17 15:51:16 +00001133- Patch #1180296: Two new functions were added to the locale module:
1134 format_string() to get the effect of "format % items" but locale-aware,
1135 and currency() to format a monetary number with currency sign.
1136
Georg Brandle3a25832006-05-17 14:56:04 +00001137- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1138 and several features added, such as speed and geometry control.
1139
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001140- Patch #1488881: add support for external file objects in bz2 compressed
1141 tarfiles.
1142
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001143- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1144 stdout arguments, making it possible to redirect input and output
1145 for remote debugging.
1146
1147- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1148 a couple of issues, notably handling of long file names using the
1149 GNU LONGNAME extension.
1150
1151- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1152 new flag when ``name`` is already the name of an option flag.
1153
1154- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1155 package.
1156
1157- Patch #1472854: make the rlcompleter.Completer class usable on non-
1158 UNIX platforms.
1159
1160- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1161
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001162- Bug #1472827: correctly escape newlines and tabs in attribute values in

1199-----------------
1200
Thomas Heller1b046642006-04-18 18:51:06 +00001201- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1202 by converting these apis from macros into exported functions again:
1203
1204 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1205 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1206 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1208 PyRun_String Py_CompileString
1209
Martin v. Löwis45294a92006-04-18 06:24:08 +00001210- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1211
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001212- All uses of PyStructSequence_InitType have been changed to initialize
1213 the type objects only once, even if the interpreter is initialized
1214 multiple times.
1215
Neal Norwitz61546162006-04-14 05:20:28 +00001216- Bug #1454485, array.array('u') could crash the interpreter. This was
1217 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1218 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1219
1220- Py_UNICODE is unsigned. It was always documented as unsigned, but
1221 due to a bug had a signed value in previous versions.
1222
Tim Peters3a5e8b12006-04-11 01:44:07 +00001223- Patch #837242: ``id()`` of any Python object always gives a positive
1224 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1225 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001226 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001227 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001228
Tim Peters3a5e8b12006-04-11 01:44:07 +00001229 def __hash__(self):
1230 return id(self) # WRONG
1231
1232 because a hash result must be a (short) Python int but it was always
1233 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001234 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001235 was always usable as a hash value before this patch. That's no longer
1236 necessarily so.
1237
1238- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001239 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001240 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001241 #1454844)
1242
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001243- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1244 involving generators that have paused outside of any ``try`` or ``with``
1245 blocks. (In 2.5a1, a paused generator that was part of a reference
1246 cycle could not be garbage collected, regardless of whether it was
1247 paused in a ``try`` or ``with`` block.)

1261 the cachesize parameter.
1262
1263- Bug #1149413: bsddb.*open() no longer raises an exception when using
1264 a temporary db (file=None) with the 'n' flag to truncate on open.
1265
1266- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1267 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001268
Armin Rigoa9017c32006-04-19 11:50:27 +00001269- Patch #1062014: AF_UNIX sockets under Linux have a special

1273-------
1274
Peter Astrand7d1d4362006-07-14 14:04:45 +00001275- Bug #1223937: subprocess.CalledProcessError reports the exit status
1276 of the process using the returncode attribute, instead of
1277 abusing errno.
1278
Tim Peters711bf302006-04-25 03:31:36 +00001279- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1280 a doctest to be skipped (the code is not run, and the expected output
1281 or exception is ignored).
1282
Nick Coghlanda2268f2006-04-24 04:37:15 +00001283- Fixed contextlib.nested to cope with exceptions being raised and
1284 caught inside exit handlers.
1285
Greg Wardab05edc2006-04-23 03:47:58 +00001286- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1287 hex, octal, or binary; add ``append_const`` action; keep going if
1288 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1289 added ``epilog`` for better help generation).
1290
Tim Peters21fbd572006-04-21 21:18:10 +00001291- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1292 called from a thread spawned as a side effect of importing a module.
1293
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001294- The pydoc module now supports documenting packages contained in
1295 .zip or .egg files.
1296
1297- The pkgutil module now has several new utility functions, such
1298 as ``walk_packages()`` to support working with packages that are either
1299 in the filesystem or zip files.
1300
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001301- The mailbox module can now modify and delete messages from
1302 mailboxes, in addition to simply reading them. Thanks to Gregory
1303 K. Johnson for writing the code, and to the 2005 Google Summer of
1304 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001305
Tim Petersc7605f22006-04-17 21:12:33 +00001306- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001315- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1316 Windows. Bug #1469163.
1317
Phillip J. Eby47032112006-04-11 01:07:43 +00001318- The warnings, linecache, inspect, traceback, site, and doctest modules
1319 were updated to work correctly with modules imported from zipfiles or
1320 via other PEP 302 __loader__ objects.

1328
Skip Montanaro262fb922006-04-21 02:31:07 +00001329- The pstats.Stats class accepts an optional stream keyword argument to
1330 direct output to an alternate file-like object.
1331
Anthony Baxter51bcb682006-04-05 14:51:42 +00001332Build
1333-----
1334
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001335- The Makefile now has a reindent target, which runs reindent.py on
1336 the library.
1337
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001338- Patch #1470875: Building Python with MS Free Compiler
1339

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001341
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001342- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1343 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001344 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001345 CXX from --with-cxx-main, see description in README.
1346
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001347- Patch #1429775: Link extension modules with the shared libpython.
1348
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001349- Fixed a libffi build problem on MIPS systems.
1350
Tim Peters8931ff12006-05-13 23:28:20 +00001351- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1352 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1353 and "%zu" for unsigned integers of type ``size_t``.
1354
Anthony Baxter51bcb682006-04-05 14:51:42 +00001355Tests
1356-----
1357
Nick Coghlanda2268f2006-04-24 04:37:15 +00001358- test_contextlib now checks contextlib.nested can cope with exceptions
1359 being raised and caught inside exit handlers.
1360
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001361- test_cmd_line now checks operation of the -m and -c command switches
1362
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001363- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1364 it separately and by hand. It also wasn't cleaning up its changes to
1365 the current Decimal context.
1366
Thomas Woutersabd08882006-04-26 15:53:30 +00001367- regrtest.py now has a -M option to run tests that test the new limits of
1368 containers, on 64-bit architectures. Running these tests is only sensible
1369 on 64-bit machines with more than two gigabytes of memory. The argument
1370 passed is the maximum amount of memory for the tests to use.

1379-------------
1380
Tim Petersb06d28c2006-05-12 01:57:59 +00001381- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1382
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001383- PEP 343: Added Context Types section to the library reference
1384 and attempted to bring other PEP 343 related documentation into
1385 line with the implementation and/or python-dev discussions.
1386
Tim Peters8dc73d22006-04-24 02:03:16 +00001387- Bug #1337990: clarified that ``doctest`` does not support examples
1388 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001391What's New in Python 2.5 alpha 1?
1392=================================
1393
Anthony Baxterebed3f62006-04-03 15:03:44 +00001394*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001395
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001396Core and builtins
1397-----------------
1398
Nick Coghlan43832302006-04-23 17:04:07 +00001399- PEP 338: -m command line switch now delegates to runpy.run_module
1400 allowing it to support modules in packages and zipfiles
1401
Martin v. Löwisc661b882006-04-20 04:54:23 +00001402- On Windows, .DLL is not an accepted file name extension for
1403 extension modules anymore; extensions are only found if they
1404 end in .PYD.
1405
Martin v. Löwisea62d252006-04-03 10:56:49 +00001406- Bug #1421664: sys.stderr.encoding is now set to the same value as
1407 sys.stdout.encoding.
1408
Neal Norwitz92e212f2006-04-03 04:48:37 +00001409- __import__ accepts keyword arguments.
1410
Georg Brandlccadf842006-03-31 18:54:53 +00001411- Patch #1460496: round() now accepts keyword arguments.
1412
Anthony Baxter262c00a2006-03-30 10:53:17 +00001413- Fixed bug #1459029 - unicode reprs were double-escaped.
1414
Hye-Shik Changd478f342006-03-23 12:32:36 +00001415- Patch #1396919: The system scope threads are reenabled on FreeBSD
1416 5.4 and later versions.
1417
Neal Norwitze98ccf62006-03-23 05:39:47 +00001418- Bug #1115379: Compiling a Unicode string with an encoding declaration
1419 now gives a SyntaxError.
1420
Georg Brandlabd1ff82006-03-18 07:59:59 +00001421- Previously, Python code had no easy way to access the contents of a
1422 cell object. Now, a ``cell_contents`` attribute has been added
1423 (closes patch #1170323).
1424
Tim Peterscf79aac2006-03-16 01:14:46 +00001425- Patch #1123430: Python's small-object allocator now returns an arena to
1426 the system ``free()`` when all memory within an arena becomes unused
1427 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1428 freed. Some applications will see a drop in virtual memory size now,
1429 especially long-running applications that, from time to time, temporarily
1430 use a large number of small objects. Note that when Python returns an
1431 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001432 platform C library will in turn return that memory to the operating system.
1433 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001434 appears to be effective at least on Microsoft C and gcc-based systems.
1435 Thanks to Evan Jones for hard work and patience.
1436
Georg Brandl533ff6f2006-03-08 18:09:27 +00001437- Patch #1434038: property() now uses the getter's docstring if there is
1438 no "doc" argument given. This makes it possible to legitimately use
1439 property() as a decorator to produce a read-only property.
1440
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001441- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1442 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1443 of requiring an int or long in slicing and a few other contexts, enabling
1444 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1445
Neal Norwitz995acdf2006-03-07 05:01:00 +00001446- Fixed various bugs reported by Coverity's Prevent tool.
1447
Brett Cannonbf364092006-03-01 04:25:17 +00001448- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1449 new exception base class, BaseException, which has a new message attribute.
1450 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1451 Raising a string exception now raises a DeprecationWarning.
1452
Thomas Woutersfb609f42006-02-28 16:37:25 +00001453- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1454 explicitly relative, using 'from .module import name' to mean 'from the same
1455 package as this module is in. Imports without dots still default to the
1456 old relative-then-absolute, unless 'from __future__ import
1457 absolute_import' is used.
1458
Brett Cannona7446e32006-02-27 23:39:10 +00001459- Properly check if 'warnings' raises an exception (usually when a filter set
1460 to "error" is triggered) when raising a warning for raising string
1461 exceptions.
1462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001463- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001464 The name was removed from Include/code.h.
1465
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001466- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001467
Guido van Rossum1968ad32006-02-25 22:38:04 +00001468- Patch 1433928:
1469 - The copy module now "copies" function objects (as atomic objects).
1470 - dict.__getitem__ now looks for a __missing__ hook before raising
1471 KeyError.
1472
Tim Peters84ef21c2006-02-28 20:39:06 +00001473- PEP 343: with statement implemented. Needs ``from __future__ import
1474 with_statement``. Use of 'with' as a variable will generate a warning.
1475 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001476 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001477 The following objects have __context__ methods:
1478 - The built-in file type.
1479 - The thread.LockType type.
1480 - The following types defined by the threading module:
1481 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1482 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001483
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001484- Fix the encodings package codec search function to only search
1485 inside its own package. Fixes problem reported in patch #1433198.
1486
1487 Note: Codec packages should implement and register their own
1488 codec search function. PEP 100 has the details.
1489
Tim Peters9ea89d22006-06-04 03:26:02 +00001490- PEP 353: Using ``Py_ssize_t`` as the index type.
1491
1492- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1493 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1494 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1495 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1496 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001497
Neal Norwitzfc76d632006-01-10 06:03:13 +00001498- Patch #1400181, fix unicode string formatting to not use the locale.
1499 This is how string objects work. u'%f' could use , instead of .
1500 for the decimal point. Now both strings and unicode always use periods.
1501
Neal Norwitz671b9e32006-01-09 07:07:12 +00001502- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1503 configure would break checking curses.h.
1504
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001505- Bug #959576: The pwd module is now builtin. This allows Python to be
1506 built on UNIX platforms without $HOME set.
1507
Neal Norwitzc10978f2005-12-19 06:07:16 +00001508- Bug #1072182, fix some potential problems if characters are signed.
1509
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001510- Bug #889500, fix line number on SyntaxWarning for global declarations.
1511
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001512- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1513
Neal Norwitze7214a12005-12-18 05:03:17 +00001514- Support for converting hex strings to floats no longer works.
1515 This was not portable. float('0x3') now raises a ValueError.
1516
Barry Warsaw2a38a862005-12-18 01:27:35 +00001517- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001518 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001519 is now displayed in interactive prompt banner.
1520
Georg Brandlfa166682005-12-17 21:45:17 +00001521- Implementation of PEP 341 - Unification of try/except and try/finally.
1522 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001523 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001524
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001525- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1526 now encodes backslash correctly.
1527
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001528- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1529
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001530- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001531 and long longs.
1532
Neal Norwitz67715f02005-11-09 06:59:35 +00001533- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001534 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001535 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001536
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001537- Replaced most Unicode charmap codecs with new ones using the
1538 new Unicode translate string feature in the builtin charmap
1539 codec; the codecs were created from the mapping tables available
1540 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1541 encodings now include a mapping for the Apple logo)
1542
Tim Peterse3547fd2005-12-16 23:13:57 +00001543- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001544
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001545- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001546
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001547- A new AST parser implementation was completed. The abstract
1548 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001549 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001550
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001551- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001552 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1553
Neal Norwitz708e51a2005-10-03 04:48:15 +00001554- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1555
Neal Norwitz11bd1192005-10-03 00:54:56 +00001556- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1557 Provide a warning when a directory is passed on the command line.
1558
Neal Norwitz40d37812005-10-02 01:48:49 +00001559- Fix segfault with invalid coding.
1560
1561- SF bug #772896: unknown encoding results in MemoryError.
1562
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001563- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001564 supported a __len__() method which evaluated to False when the iterator
1565 was empty.
1566
Guido van Rossum630db602005-09-20 18:49:54 +00001567- On 64-bit platforms, when __len__() returns a value that cannot be
1568 represented as a C int, raise OverflowError.
1569
Skip Montanarof8948ca2005-09-19 03:54:46 +00001570- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001571 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001572
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001573- SF bug #893549: parsing keyword arguments was broken with a few format
1574 codes.
1575
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001576- Changes donated by Elemental Security to make it work on AIX 5.3
1577 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1578 bug #105470: test_pwd fails on 64bit system (Opteron).
1579
Guido van Rossum539c6622005-09-14 17:49:54 +00001580- Changes donated by Elemental Security to make it work on HP-UX 11 on
1581 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1582
Georg Brandl4550b8d2005-08-26 06:43:52 +00001583- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001584 (fixes bug #1119418).
1585
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001586- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1587
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001588- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1589 exceptions that cause a function to exit.
1590
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001591- The implementation of set() and frozenset() was revised to use its
1592 own internal data structure. Memory consumption is reduced by 1/3
1593 and there are modest speed-ups as well. The API is unchanged.
1594
Tim Petersde7990b2005-07-17 23:45:23 +00001595- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1596
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001597- SF bug #1229429: PyObject_CallMethod failed to decrement some
1598 reference counts in some error exit cases.
1599
Tim Petersecc6e6a2005-07-10 22:30:55 +00001600- SF bug #1185883: Python's small-object memory allocator took over
1601 a block managed by the platform C library whenever a realloc specified
1602 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001603 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001604 portable way to copy data from the C-managed block into Python's
1605 small-object space without risking a memory fault. Python's small-object
1606 realloc now leaves such blocks under the control of the platform C
1607 realloc.
1608
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001609- SF bug #1232517: An overflow error was not detected properly when
1610 attempting to convert a large float to an int in os.utime().
1611
Raymond Hettinger3296e692005-06-29 23:29:56 +00001612- SF bug #1224347: hex longs now print with lowercase letters just
1613 like their int counterparts.
1614
Michael W. Hudson188d4362005-06-20 16:52:57 +00001615- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1616 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1617 interpreter states; back out that fix and do a better job (see
1618 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1619 for a longer write-up of the problem).
1620
Michael W. Hudsondf888462005-06-03 14:41:55 +00001621- SF patch #1180995: marshal now uses a binary format by default when
1622 serializing floats.
1623
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001624- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1625 the routines that promise to produce IEEE 754 binary representations
1626 of floats now simply copy bytes around.
1627
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001628- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1629 278.
1630
Brett Cannonc3647ac2005-04-26 03:45:26 +00001631- patch #1109424: int, long, float, complex, and unicode now check for the
1632 proper magic slot for type conversions when subclassed. Previously the
1633 magic slot was ignored during conversion. Semantics now match the way
1634 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001635 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001636 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001637 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001638
Barry Warsawc8d907c2005-04-19 23:43:40 +00001639- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1640 NULL, now raise an AttributeError when attempting to set or delete the
1641 attribute. Previously a TypeError was raised, but this was inconsistent
1642 with the equivalent pure-Python implementation.
1643
Michael W. Hudson774479c2005-04-18 08:46:17 +00001644- It is now safe to call PyGILState_Release() before
1645 PyEval_InitThreads() (note that if there is reason to believe there
1646 are multiple threads around you still must call PyEval_InitThreads()
1647 before using the Python API; this fix is for extension modules that
1648 have no way of knowing if Python is multi-threaded yet).
1649
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001650- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1651 disabled caused a crash.
1652
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001653- Bug #1165306: instancemethod_new allowed the creation of a method
1654 with im_class == im_self == NULL, which caused a crash when called.
1655
Tim Petersecc6e6a2005-07-10 22:30:55 +00001656- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001657 fixes the crash seen in bug #1165761
1658
Raymond Hettinger96229b12005-03-11 06:49:40 +00001659- Added two new builtins, any() and all().
1660
Brett Cannon409d8f22005-03-05 06:47:57 +00001661- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001662 (e.g., ``class C(): pass`` is no longer a syntax error).
1663 Patch #1176012 added support to the 'parser' module and 'compiler' package
1664 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001665
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001666- Patch #1115086: Support PY_LONGLONG in structmember.
1667
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001668- Bug #1155938: new style classes did not check that __init__() was
1669 returning None.
1670
Tim Petersecc6e6a2005-07-10 22:30:55 +00001671- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001672 ('\') with a specific error message.
1673
Martin v. Löwisff232d72005-03-03 09:24:38 +00001674- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1675
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001676- Bug #1124295: the __name__ attribute of file objects was
1677 inadvertently made inaccessible in restricted mode.
1678
Tim Petersecc6e6a2005-07-10 22:30:55 +00001679- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001680 an ferror() call.
1681
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001682- min() and max() now support key= arguments with the same meaning as in
1683 list.sort().
1684
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001685- The peephole optimizer now performs simple constant folding in expressions:
1686 (2+3) --> (5).
1687
Raymond Hettingera422c342005-01-11 03:03:27 +00001688- set and frozenset objects can now be marshalled. SF #1098985.
1689
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001690- Bug #1077106: Poor argument checking could cause memory corruption
1691 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001692
Jeremy Hyltonab630502005-02-04 18:44:06 +00001693- The parser did not complain about future statements in illegal
1694 positions. It once again reports a syntax error if a future
1695 statement occurs after anything other than a doc string.
1696
Neil Schemenauercf52c072005-08-12 17:34:58 +00001697- Change the %s format specifier for str objects so that it returns a
1698 unicode instance if the argument is not an instance of basestring and
1699 calling __str__ on the argument returns a unicode instance.
1700
Tim Petersf4e69282006-02-27 17:15:31 +00001701- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1702 current thread state when the auto-GIL-state machinery knows about
1703 it (since the thread state is being deleted, continuing to remember it
1704 can't help, but can hurt if another thread happens to get created with
1705 the same thread id).
1706
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001707Extension Modules
1708-----------------
1709
Georg Brandl43f08a82006-03-31 18:01:16 +00001710- Patch #1380952: fix SSL objects timing out on consecutive read()s
1711

1713
Anthony Baxterfa869072006-03-20 05:21:58 +00001714- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1715 In addition, the existing ulaw code was updated.
1716
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001717- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001718 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001719
Neal Norwitz10be10c2006-03-16 06:50:13 +00001720- Everything under lib-old was removed. This includes the following modules:
1721 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001722 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001723 util, whatsound, whrandom, zmod
1724
1725- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1726
1727- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001728 is deprecated. The undocumented re.engine variable no longer exists.
1729
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001730- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1731 SS2 (single-shift 2) escape sequences correctly.
1732
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001733- The unicodedata module was updated to the 4.1 version of the Unicode
1734 database. The 3.2 version is still available as unicodedata.db_3_2_0
1735 for applications that require this specific version (such as IDNA).
1736
Neal Norwitzb62c4332006-03-04 18:35:47 +00001737- The timing module is no longer built by default. It was deprecated
1738 in PEP 4 in Python 2.0 or earlier.
1739
Guido van Rossum1968ad32006-02-25 22:38:04 +00001740- Patch 1433928: Added a new type, defaultdict, to the collections module.
1741 This uses the new __missing__ hook behavior added to dict (see above).
1742
Georg Brandldbd83392006-02-20 09:42:33 +00001743- Bug #854823: socketmodule now builds on Sun platforms even when
1744 INET_ADDRSTRLEN is not defined.
1745
Georg Brandlf4f44152006-02-18 22:29:33 +00001746- Patch #1393157: os.startfile() now has an optional argument to specify
1747 a "command verb" to invoke on the file.
1748
Neal Norwitz082b2df2006-02-07 07:04:46 +00001749- Bug #876637, prevent stack corruption when socket descriptor
1750 is larger than FD_SETSIZE.
1751
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001752- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1753 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1754 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1755
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001756- Patch #1422385: The nis module now supports access to domains other
1757 than the system default domain.
1758
Martin v. Löwis14694662006-02-03 12:54:16 +00001759- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1760 are reported, the limit on path name lengths is removed, and stat reports
1761 WindowsError now (instead of OSError).
1762
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001763- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1764
Neal Norwitz62a21122006-01-25 05:21:55 +00001765- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1766 before the env.
1767
Martin v. Löwis11017b12006-01-14 18:12:57 +00001768- Patch #1103116: Basic AF_NETLINK support.
1769
Neal Norwitz3b4fff82006-01-11 08:54:45 +00001770- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001897- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1898 been renamed to have only a single underscore prefix. This was done to
1899 make subclassing easier.

Nick Coghlan43832302006-04-23 17:04:07 +00001901- PEP 338: new module runpy defines a run_module function to support
1902 executing modules which provide access to source code or a code object
1903 via the PEP 302 import mechanisms.
1904
Anthony Baxter93f5b932006-04-03 08:05:07 +00001905- The email module's parsedate_tz function now sets the daylight savings

1913 in attribute values.
1914
Anthony Baxterc51ee692006-04-01 00:57:31 +00001915- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001916 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001917 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001918 module will not be built.
1919
Tim Petersc17976e2006-04-01 00:26:53 +00001920- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1921 aren't officially supported here, and trying to use them will probably
1922 raise an exception some day. But dicts have been allowed, and "mostly
1923 worked", so support for them won't go away without warning.
1924
Georg Brandl338ef7d2006-03-31 18:42:16 +00001925- Bug #1445068: getpass.getpass() can now be given an explicit stream

1943
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001944- email 4.0 package now integrated. This is largely the same as the email 3.0
1945 package that was included in Python 2.3, except that PEP 8 module names are
1946 now used (e.g. mail.message instead of email.Message). The MIME classes
1947 have been moved to a subpackage (e.g. email.mime.text instead of
1948 email.MIMEText). The old names are still supported for now. Several
1949 deprecated Message methods have been removed and lots of bugs have been
1950 fixed. More details can be found in the email package documentation.
1951
Walter Dörwald40108c92006-03-27 08:15:44 +00001952- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1953 (a subclass of tuple) that provides incremental decoders and encoders
1954 (a way to use stateful codecs without the stream API). Python functions
1955 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1956 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1957 have been added.

1960 a ValueError instead of a StopIteration now (like file and cString.String do).
1961 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1962 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002036 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2037 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2038 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2039 Ronald L. Rivest offered this advice for Python:
2040
2041 "The consensus of researchers in this area (at least as
2042 expressed at the NIST Hash Function Workshop 10/31/05),
2043 is that SHA-256 is a good choice for the time being, but
2044 that research should continue, and other alternatives may
2045 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002046
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002047- Added a subset of Fredrik Lundh's ElementTree package. Available

2100 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002101 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002102

2140 Bug #1224621.
2141
Raymond Hettinger68c04532005-06-10 11:05:19 +00002142- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002143 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002144 the generate_tokens() function now accepts a callable argument that
2145 terminates by raising StopIteration.
2146
Georg Brandl9166e1a2005-06-04 09:20:03 +00002147- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2155 class at all.
2156
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002157- distutils.commands.upload was added to support uploading distribution

2161 them to PyPI.
2162
Raymond Hettinger267b8682005-03-27 10:47:39 +00002163- decimal operator and comparison methods now return NotImplemented
2164 instead of raising a TypeError when interacting with other types. This
2165 allows other classes to implement __radd__ style methods and have them
2166 work as expected.
2167
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002168- Bug #1163325: Decimal infinities failed to hash. Attempting to
2169 hash a NaN raised an InvalidOperation instead of a TypeError.
2170
Tim Petersecc6e6a2005-07-10 22:30:55 +00002171- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002172 stream compression; add, for symmetry reasons, r:* as a synonym of r.

2205
Guido van Rossumd0641422005-02-03 15:01:24 +00002206- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2207 disables recursive traversal through instance attributes, which can
2208 be exploited in various ways.
2209
Tim Peterse3547fd2005-12-16 23:13:57 +00002210- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002211 flags on the HTTP listening socket.
2212
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002213- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2214 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2215

2222
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002223- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2224
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002225- Enhancements to the csv module:
2226
2227 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002228 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002229 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002230 + Dialect parameter parsing has been re-implemented to improve error
2231 reporting.
2232 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2233 dictates.
2234 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002235 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002236 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002237 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2238 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002239 + reader now allows \r characters to be quoted (previously it only allowed
2240 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002241 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002242 + Dialect classes passed to the module are no longer instantiated by
2243 the module before being parsed (the former validation scheme required
2244 this, but the mechanism was unreliable).
2245 + The dialect registry now contains instances of the internal
2246 C-coded dialect type, rather than references to python objects.
2247 + the internal c-coded dialect type is now immutable.
2248 + register_dialect now accepts the same keyword dialect specifications
2249 as the reader and writer, allowing the user to register dialects
2250 without first creating a dialect class.
2251 + a configurable limit to the size of parsed fields has been added -
2252 previously, an unmatched quote character could result in the entire
2253 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002254 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002255 the parser field size limit (returning the former limit). The initial
2256 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002257 + A line_num attribute has been added to the reader object, which tracks
2258 the number of lines read from the source iterator. This is not
2259 the same as the number of records returned, as records can span
2260 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002261 + reader and writer objects were not being registered with the cyclic-GC.
2262 This has been fixed.
2263
Brett Cannone6539c42005-01-08 02:43:53 +00002264- _DummyThread objects in the threading module now delete self.__block that is
2265 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2266 lock primitives tend to be limited in number and thus should not be wasted on
2267 a _DummyThread object. Fixes bug #1089632.
2268
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002269- The imghdr module now detects Exif files.
2270
Raymond Hettinger6065d322004-12-20 23:51:53 +00002271- StringIO.truncate() now correctly adjusts the size attribute.
2272 (Bug #951915).
2273
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002274- locale.py now uses an updated locale alias table (built using
2275 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2276 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002277 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002278
Raymond Hettinger3557f422004-12-07 12:02:02 +00002279- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2280
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002281- the pickle module no longer accepts the deprecated None option in the
2282 args tuple returned by __reduce__().
2283
Brett Cannon84667c02004-12-07 03:25:18 +00002284- optparse now optionally imports gettext. This allows its use in setup.py.
2285
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002286- the pickle module no longer uses the deprecated bin parameter.
2287
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002288- the shelve module no longer uses the deprecated binary parameter.
2289
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002290- the pstats module no longer uses the deprecated ignore() method.
2291
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002292- the filecmp module no longer uses the deprecated use_statcache argument.
2293
Raymond Hettinger664347b2004-12-04 21:21:53 +00002294- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2295 extended or overridden by subclasses. Formerly, the subclassed method would
2296 be ignored by the rest of the module. (Bug #1078905).
2297
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002298- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002299 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002300
Walter Dörwald36733692004-12-22 12:50:50 +00002301- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2302 once when a size argument is given. This prevents a buffer overflow in the
2303 tokenizer with very long source lines.
2304
Barry Warsaw538561e2006-01-01 21:48:54 +00002305- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2306 immediately after creating the object, without any intervening
2307 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002308
Skip Montanaro05885812005-01-16 20:48:27 +00002309- The reconvert.quote function can now emit triple-quoted strings. The
2310 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002311
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002312- ``UserString.MutableString`` now supports negative indices in
2313 ``__setitem__`` and ``__delitem__``
2314
Greg Ward40407942005-03-05 02:53:17 +00002315- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2316 correctly.
2317
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002318- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2319 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2320 character even if the user has passed a size parameter to get a proper
2321 line ending. Remove the special handling of a "\r\n" that has been split
2322 between two lines.
2323
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002324- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2325 about illegal code points. The codec now supports PEP 293 style error
2326 handlers.
2327
Walter Dörwald78a78b02005-09-01 12:04:29 +00002328- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002329 from the input stream, so that the output is a byte string in the correct
2330 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002331
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002332- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2333 considering it exactly like a '*'.
2334
Walter Dörwald007f8df2005-10-09 19:42:27 +00002335- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2336 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002337
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002338- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2339
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002340- Patch #1413711: Certain patterns of differences were making difflib
2341 touch the recursion limit.
2342
Walter Dörwald58917a62006-03-31 15:26:22 +00002343- Bug #947906: An object oriented interface has been added to the calendar
2344 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002345 called as a script (e.g. via ``python -mcalendar``). Localized month and
2346 weekday names can be ouput (even if an exotic encoding is used) using
2347 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002348
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002349Build
2350-----
2351
Neal Norwitz602d3392006-03-31 08:21:40 +00002352- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2353 by using -mieee gcc option.
2354

2356
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002357- Build support for Win64-AMD64 was added.
2358
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002359- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2360
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002361- Patch #881820: look for openpty and forkpty also in libbsd.
2362
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002363- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2364 The zlib module is now builtin on Windows.
2365
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002366- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2367
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002368- Bug #1189330: configure did not correctly determine the necessary
2369 value of LINKCC if python was built with GCC 4.0.
2370
Trent Mick8321b422005-07-26 02:29:21 +00002371- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2372 vulnerability in zlib 1.2.1 and 1.2.2.
2373
Brett Cannon08cd5982005-04-24 22:26:38 +00002374- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2375 flags that change binary compatibility. Changes were also made to
2376 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002377 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002378
Bob Ippolitoed233462005-03-29 13:47:59 +00002379- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2380 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2381 no longer exists). This configure patch makes things right.
2382
Martin v. Löwise2713be2005-03-08 15:03:08 +00002383- Bug #1158607: Build with --disable-unicode again.
2384
Brett Cannon46d96232005-02-16 00:07:19 +00002385- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2386 defined. Discovered as a result of not being able to build on OS X.
2387
Brett Cannon516592f2004-12-07 00:42:59 +00002388- setup.py now uses the directories specified in LDFLAGS using the -L option
2389 and in CPPFLAGS using the -I option for adding library and include
2390 directories, respectively, for compiling extension modules against. This has
2391 led to the core being compiled using the values in CPPFLAGS. It also removes
2392 the need for the special-casing of both DarwinPorts and Fink for darwin since
2393 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2394 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2395 Fink, ``-I/opt/local/include`` for DarwinPorts).
2396
Brett Cannon43802422005-02-10 20:48:03 +00002397- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2398 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2399 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2400 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002402C API
2403-----
2404
Tim Petersc9d78aa2006-03-26 23:27:58 +00002405- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2406 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2407 is obtained via the ``PyObject_`` family, it must be released via the
2408 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2409 always been officially true, but when Python's small-object allocator was
2410 introduced, an attempt was made to cater to a few extension modules
2411 discovered at the time that obtained memory via ``PyObject_New`` but
2412 released it via ``PyMem_DEL``. It's years later, and if such code still
2413 exists it will fail now (probably with segfaults, but calling wrong
2414 low-level memory management functions can yield many symptoms).
2415
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002416- Added a C API for set and frozenset objects.
2417
Raymond Hettinger66517482004-12-03 11:45:13 +00002418- Removed PyRange_New().
2419
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002420- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2421 mapping argument now. This string is used as a mapping table. Byte values
2422 greater than the length of the string and 0xFFFE are treated as undefined
2423 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002429- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002430
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002431- Patch #1276356: New resource "urlfetch" is implemented. This enables
2432 even impatient people to run tests that require remote files.
