Guido van Rossumc69ac252006-08-10 18:09:25 +0000356What's New in Python 2.5 release candidate 1?

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000360
361Core and builtins
362-----------------
363
Neal Norwitz24b6f202006-09-05 04:43:56 +0000364- Fix infinite recursion when subclassing long and overriding __hash__.
365
366- Fix concatenation (+=) of long strings.
367
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000368- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000369 compared equal or unequal to a string and a UnicodeDecodeError
370 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000371
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000372 Instead, the equal (==) and unequal (!=) comparison operators will
373 now issue a UnicodeWarning and interpret the two objects as
374 unequal. The UnicodeWarning can be filtered as desired using
375 the warning framework, e.g. silenced completely, turned into an
376 exception, logged, etc.
377
378 Note that compare operators other than equal and unequal will still
379 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000380
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000381- Fix segfault when doing string formatting on subclasses of long.
382
383- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
384 with new-style classes.
385
386- Fix bug related to __len__ functions returning negative values with
387 classic classes.
388
389- Patch #1538606, Fix __index__() clipping. There were some problems
390 discovered with the API and how integers that didn't fit into Py_ssize_t
391 were handled. This patch attempts to provide enough alternatives
392 to effectively use __index__.
393
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000394- Bug #1536021: __hash__ may now return long int; the final hash
395 value is obtained by invoking hash on the long int.
396
Thomas Hellerab1049c2006-08-08 17:37:00 +0000397- Bug #1536786: buffer comparison could emit a RuntimeWarning.
398
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000399- Bug #1535165: fixed a segfault in input() and raw_input() when
400 sys.stdin is closed.
401
Thomas Heller74d36f02006-08-04 18:17:40 +0000402- On Windows, the PyErr_Warn function is now exported from
403 the Python dll again.
404
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000405- Bug #1191458: tracing over for loops now produces a line event
406 on each iteration. Fixing this problem required changing the .pyc
407 magic number. This means that .pyc files generated before 2.5c1
408 will be regenerated.
409
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000410- Bug #1333982: string/number constants were inappropriately stored
411 in the byte code and co_consts even if they were not used, ie
412 immediately popped off the stack.
413
Georg Brandle9462c72006-08-04 18:03:37 +0000414- Fixed a reference-counting problem in property().
415
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000416
417Library
418-------
419
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000420- Fix a bug in the ``compiler`` package that caused invalid code to be
421 generated for generator expressions.
422
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000423- The distutils version has been changed to 2.5.0. The change to
424 keep it programmatically in sync with the Python version running
425 the code (introduced in 2.5b3) has been reverted. It will continue
426 to be maintained manually as static string literal.
427
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000428- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000429 and this cannot be converted to the required C type, an exception is
430 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000431 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000432
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000433- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000434 an exception.
435
Tim Peterscbdd3502006-09-05 01:47:53 +0000436- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000437 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000438 workarounds for clocks with low resolution, to stop the code yielding
439 duplicate UUIDs.
440
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000441- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
442 before raising SystemExit, allowing IDLE to honor quit() and exit().
443
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000444- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
445
Georg Brandl7a1af772006-08-14 21:55:28 +0000446- Patch #1536071: trace.py should now find the full module name of a
447 file correctly even on Windows.
448
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000449- logging's atexit hook now runs even if the rest of the module has
450 already been cleaned up.
451
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000452- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000453
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000454- Bug #1531405, format_exception no longer raises an exception if
455 str(exception) raised an exception.
456
Neil Schemenauer06ded092006-08-04 16:20:30 +0000457- Fix a bug in the ``compiler`` package that caused invalid code to be
458 generated for nested functions.
459
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000460
461Extension Modules

465
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000466- Patch #1511317: don't crash on invalid hostname (alias) info.
467
Georg Brandl3335a7a2006-08-14 21:42:55 +0000468- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
469 raises the correct exceptions.
470
Thomas Heller1ce433e2006-08-14 16:20:04 +0000471- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
472 '-no-stack-protector' compiler flag for OpenBSD has been removed.
473
Thomas Heller86720042006-08-14 11:17:48 +0000474- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
475 uses the _as_parameter_ attribute when objects are passed to foreign
476 function calls. The ctypes version number was changed to 1.0.1.
477
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000478- Bug #1530559, struct.pack raises TypeError where it used to convert.
479 Passing float arguments to struct.pack when integers are expected
480 now triggers a DeprecationWarning.
481
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000482

Neal Norwitza1f10902006-07-12 07:28:29 +0000527
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000528*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000529
530Core and builtins
531-----------------
532
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000533- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000534 returned a long (see PEP 353).
535
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000536- Bug #1515471: string.replace() accepts character buffers again.
537
Neal Norwitz07aadb12006-07-30 06:55:48 +0000538- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
539 This provides the proper warning for struct.pack().
540 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
541
Neal Norwitz0d62a062006-07-30 06:53:31 +0000542- Patch #1531113: Fix augmented assignment with yield expressions.
543 Also fix a SystemError when trying to assign to yield expressions.
544
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000545- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
546 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
547 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
548 excessive filesystem operations during imports.
549
Tim Petersbc24eee2006-07-27 01:14:53 +0000550- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
551 operations on signed longs that are formally undefined by C.
552 Unfortunately, at least one compiler now cares about that, so complicated
553 the code to make that compiler happy again.
554
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000555- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
556
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000557- Patch #1232023: Stop including current directory in search
558 path on Windows.
559
Neal Norwitze1fdb322006-07-21 05:32:28 +0000560- Fix some potential crashes found with failmalloc.
561
Neal Norwitze7563102006-07-17 01:00:16 +0000562- Fix warnings reported by Klocwork's static analysis tool.
563
Neal Norwitz84be93b2006-07-16 01:50:38 +0000564- Bug #1512814, Fix incorrect lineno's when code within a function
565 had more than 255 blank lines.
566
Georg Brandl9dceedb2006-07-12 15:31:17 +0000567- Patch #1521179: Python now accepts the standard options ``--help`` and
568 ``--version`` as well as ``/?`` on Windows.
569
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000570- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000571 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000572 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000573
Tim Peters112aad32006-07-19 00:03:19 +0000574- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000575 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000576 new ``sys._current_frames()`` returns a dictionary with one entry,
577 mapping the faux "thread id" 0 to the current frame.
578
Ronald Oussoren3075e162006-07-25 20:28:55 +0000579- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000580
Ronald Oussoren3075e162006-07-25 20:28:55 +0000581
Neal Norwitza1f10902006-07-12 07:28:29 +0000582Library
583-------
584
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000585- Correction of patch #1455898: In the mbcs decoder, set final=False
586 for stream decoder, but final=True for the decode function.
587
Georg Brandl07fec3a2006-08-01 18:49:24 +0000588- os.urandom no longer masks unrelated exceptions like SystemExit or
589 KeyboardInterrupt.
590
Tim Peters4643c2f2006-08-10 22:45:34 +0000591- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000592 shutil.copytree on Windows
593
Georg Brandle34ac7c2006-07-30 11:07:23 +0000594- Bug #1002398: The documentation for os.path.sameopenfile now correctly
595 refers to file descriptors, not file objects.
596
Tim Peterscbdd3502006-09-05 01:47:53 +0000597- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000598 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000599 #1513611, and probably others.
600
Georg Brandledd9b0d2006-07-29 09:33:26 +0000601- Bug #1441397: The compiler module now recognizes module and function
602 docstrings correctly as it did in Python 2.4.
603
Tim Peters6f681472006-07-27 23:44:37 +0000604- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
605 lost that tests are sorted by name before being run. This rarely
606 matters for well-written tests, but can create baffling symptoms if
607 side effects from one test to the next affect outcomes. ``DocTestFinder``
608 has been changed to sort the list of tests it returns.
609
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000610- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000611 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000612
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000613- Bug #978833: Really close underlying socket in _socketobject.close.
614
Georg Brandldb232dc2006-08-20 13:15:43 +0000615- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
616 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000617
Georg Brandlcf0c1722006-07-26 07:23:32 +0000618- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
619 to recursive calls and call it with the failing package name.
620
Martin v. Löwis0b483032006-07-25 09:53:12 +0000621- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
622
Georg Brandlc13c34c2006-07-24 14:09:56 +0000623- Patch #1515343: Fix printing of deprecated string exceptions with a
624 value in the traceback module.
625
Greg Ward48fae7a2006-07-23 16:05:51 +0000626- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
627
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000628- Patch #1524429: Use repr() instead of backticks in Tkinter again.
629
Brett Cannoncaebe222006-07-18 04:41:36 +0000630- Bug #1520914: Change time.strftime() to accept a zero for any position in its
631 argument tuple. For arguments where zero is illegal, the value is forced to
632 the minimum value that is correct. This is to support an undocumented but
633 common way people used to fill in inconsequential information in the time
634 tuple pre-2.4.
635
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000636- Patch #1220874: Update the binhex module for Mach-O.
637
Barry Warsawb110bad2006-07-21 14:51:07 +0000638- The email package has improved RFC 2231 support, specifically for
639 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
640 (name*0=<blah>) parameter continuations. This may change the types of
641 values returned from email.message.Message.get_param() and friends.
642 Specifically in some cases where non-encoded continuations were used,
643 get_param() used to return a 3-tuple of (None, None, string) whereas now it
644 will just return the string (since non-encoded continuations don't have
645 charset and language parts).
646
647 Also, whereas % values were decoded in all parameter continuations, they are
648 now only decoded in encoded parameter parts.
649
Ronald Oussoren3075e162006-07-25 20:28:55 +0000650- Bug #1517990: IDLE keybindings on MacOS X now work correctly
651
652- Bug #1517996: IDLE now longer shows the default Tk menu when a
653 path browser, class browser or debugger is the frontmost window on MacOS X
654
Barry Warsaw00decd72006-07-27 23:43:15 +0000655- Patch #1520294: Support for getset and member descriptors in types.py,
656 inspect.py, and pydoc.py. Specifically, this allows for querying the type
657 of an object against these built-in types and more importantly, for getting
658 their docstrings printed in the interactive interpreter's help() function.

665 a socket operation on a socket with a timeout, the exception will be
666 caught correctly. Previously, the exception was not caught.
667
Thomas Heller1393d6a2006-07-28 21:43:20 +0000668- Patch #1529514: The _ctypes extension is now compiled on more
669 openbsd target platforms.
670
Tim Peters9cab5932006-07-28 00:30:00 +0000671- The ``__reduce__()`` method of the new ``collections.defaultdict`` had

Thomas Hellerce049a02006-07-14 17:51:14 +0000679- Patch #1521817: Index range checking on ctypes arrays containing
680 exactly one element enabled again. This allows iterating over these
681 arrays, without the need to check the array size before.
682
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000683- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000684 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000685 /dev/null in certain cases; this is now fixed.
686
Thomas Heller47d7a062006-07-12 08:43:47 +0000687- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
688 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000689
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000690- Because of a misspelled preprocessor symbol, ctypes was always
691 compiled without thread support; this is now fixed.
692
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000693- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
694 methods now allow their database parameter to be None as the
695 sleepycat API allows.
696
Matt Flemingec926502006-07-28 11:27:27 +0000697- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
698 bluetooth API compared with Linux and FreeBSD.

701-----
702
703- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
704 how long the test file should take to play. Now accepts taking 2.93 secs
705 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
706
Georg Brandl4793aa32006-07-28 18:31:39 +0000707- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
708 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
709 run via ``regrtest.py``. Now they do.

719- PythonLauncher now works correctly when the path to the script contains
720 characters that are treated specially by the shell (such as quotes).
721
722- Bug #1527397: PythonLauncher now launches scripts with the working directory
723 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000724 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000725 expect.

734-----------------
735
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000736- Bug #1441486: The literal representation of -(sys.maxint - 1)
737 again evaluates to a int object, not a long.
738
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000739- Bug #1501934: The scope of global variables that are locally assigned
740 using augmented assignment is now correctly determined.
741
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000742- Bug #927248: Recursive method-wrapper objects can now safely
743 be released.
744
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000745- Bug #1417699: Reject locale-specific decimal point in float()
746 and atof().
747
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000748- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
749 omit a default "error" argument for NULL pointer. This allows
750 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000751
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000752- Bug #1519018: 'as' is now validated properly in import statements.
753
Neal Norwitz28746ab2006-07-09 22:14:42 +0000754- On 64 bit systems, int literals that use less than 64 bits are
755 now ints rather than longs.
756
Neal Norwitzed657552006-07-10 00:04:44 +0000757- Bug #1512814, Fix incorrect lineno's when code at module scope
758 started after line 256.
759
Tim Peters32a83612006-07-10 21:08:24 +0000760- New function ``sys._current_frames()`` returns a dict mapping thread
761 id to topmost thread stack frame. This is for expert use, and is
762 especially useful for debugging application deadlocks. The functionality
763 was previously available in Fazal Majid's ``threadframe`` extension
764 module, but it wasn't possible to do this in a wholly threadsafe way from
765 an extension.

812
Brett Cannon53ab5b72006-06-22 16:49:14 +0000813- Bug #1510580: The 'warnings' module improperly required that a Warning
814 category be either a types.ClassType and a subclass of Warning. The proper
815 check is just that it is a subclass with Warning as the documentation states.
816
Georg Brandlad29e632006-06-21 17:45:17 +0000817- The compiler module now correctly compiles the new try-except-finally
818 statement (bug #1509132).
819
Neal Norwitz60373cd2006-06-22 06:30:50 +0000820- The wsgiref package is now installed properly on Unix.

823 shutdown when fileConfig() was called multiple times.
824
Gerhard Häring762fbd32006-07-02 17:48:30 +0000825- The sqlite3 module did cut off data from the SQLite database at the first

Tim Peters112aad32006-07-19 00:03:19 +0000832- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
833 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
834 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000835
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000836- Assigning None to pointer type fields in ctypes structures possible
837 overwrote the wrong fields, this is fixed now.
838
839- Fixed a segfault in _ctypes when ctypes.wintypes were imported
840 on non-Windows platforms.
841
842- Bug #1518190: The ctypes.c_void_p constructor now accepts any
843 integer or long, without range checking.
844
845- Patch #1517790: It is now possible to use custom objects in the ctypes
846 foreign function argtypes sequence as long as they provide a from_param
847 method, no longer is it required that the object is a ctypes type.
848

867
Tim Peters32a83612006-07-10 21:08:24 +0000868- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000869 Previously, the slight difference could cause compilation errors of the
870 'zlib' module on systems with more than one version of zlib.
871
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000872- The MSI compileall step was fixed to also support a TARGETDIR

919 attribute on objects until one without one is found. This leads to recursion
920 when you take a class and set its __call__ attribute to an instance of the
921 class. Originally fixed for classic classes, but this fix is for new-style.
922 Removes the infinite_rec_3 crasher.
923
Georg Brandl24250812006-06-09 18:45:48 +0000924- The string and unicode methods startswith() and endswith() now accept
925 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
926
Brett Cannonde3b0522006-06-08 17:00:45 +0000927- Buffer objects, at the C level, never used the char buffer
928 implementation even when the char buffer for the wrapped object was
929 explicitly requested (originally returned the read or write buffer).
930 Now a TypeError is raised if the char buffer is not present but is
931 requested.
932
Georg Brandlddbaa662006-06-04 21:56:52 +0000933- Patch #1346214: Statements like "if 0: suite" are now again optimized
934 away like they were in Python 2.4.
935
Georg Brandlb7c8f542006-05-27 12:30:25 +0000936- Builtin exceptions are now full-blown new-style classes instead of
937 instances pretending to be classes, which speeds up exception handling
938 by about 80% in comparison to 2.5a2.
939
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000940- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
941 Unicode 4.1.
942
Georg Brandlf4ef1162006-05-26 18:03:31 +0000943- Patch #921466: sys.path_importer_cache is now used to cache valid and
944 invalid file paths for the built-in import machinery which leads to
945 fewer open calls on startup.
946
Tim Peters696cf432006-05-24 21:10:40 +0000947- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
948 of-2 bases. The largest speedup is for inputs with about 1000 decimal
949 digits. Conversion from non-power-of-2 bases remains quadratic-time in
950 the number of input digits (it was and remains linear-time for bases
951 2, 4, 8, 16 and 32).
952
Tim Petersb713ec22006-05-23 18:45:30 +0000953- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
954 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
955 an integer close to ``sys.maxint``. This was repaired by patch
956 #1335972, which also gives a nice speedup.
957
Richard Jonescebbefc2006-05-23 18:28:17 +0000958- Patch #1337051: reduced size of frame objects.
959
960- PyErr_NewException now accepts a tuple of base classes as its
961 "base" parameter.
962
Richard Jones7c88dcc2006-05-23 10:37:38 +0000963- Patch #876206: function call speedup by retaining allocated frame
964 objects.
965
Georg Brandl7b90e162006-05-18 07:01:27 +0000966- Bug #1462152: file() now checks more thoroughly for invalid mode
967 strings and removes a possible "U" before passing the mode to the
968 C library function.
969
Neal Norwitz1004a532006-05-15 07:17:23 +0000970- Patch #1488312, Fix memory alignment problem on SPARC in unicode
971
Neal Norwitz373f0a72006-05-15 07:04:36 +0000972- Bug #1487966: Fix SystemError with conditional expression in assignment
973
Martin v. Löwis879768d2006-05-11 13:28:43 +0000974- WindowsError now has two error code attributes: errno, which carries
975 the error values from errno.h, and winerror, which carries the error
976 values from winerror.h. Previous versions put the winerror.h values
977 (from GetLastError()) into the errno attribute.
978
Martin v. Löwis77736712006-05-04 05:51:03 +0000979- Patch #1475845: Raise IndentationError for unexpected indent.
980
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000981- Patch #1479181: split open() and file() from being aliases for each other.
982
Tim Peters44bd9862006-06-01 13:49:23 +0000983- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
984 methods were always silently ignored by dictionaries when comparing keys.
985 They are now passed through (except when using the C API function
986 ``PyDict_GetItem()``, whose semantics did not change).
987
988- Bug #1456209: In some obscure cases it was possible for a class with a
989 custom ``__eq__()`` method to confuse dict internals when class instances
990 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
991 No, you don't have any code that did this ;-)

994-----------------
995
Trent Mick960a3f82006-06-28 20:30:41 +0000996- Bug #1295808: expat symbols should be namespaced in pyexpat
997
998- Patch #1462338: Upgrade pyexpat to expat 2.0.0
999
Brett Cannon6ee7d012006-06-08 16:23:04 +00001000- Change binascii.hexlify to accept a read-only buffer instead of only a char
1001 buffer and actually follow its documentation.
1002
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001003- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1004
Nick Coghlanc649ec52006-05-29 12:43:05 +00001005- Patch #1478788 (modified version): The functional extension module has
1006 been renamed to _functools and a functools Python wrapper module added.
1007 This provides a home for additional function related utilities that are
1008 not specifically about functional programming. See PEP 309.
1009
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001010- Patch #1493701: performance enhancements for struct module.
1011
Georg Brandl378d5922006-05-17 14:26:50 +00001012- Patch #1490224: time.altzone is now set correctly on Cygwin.
1013
Georg Brandl8d3342b2006-05-16 07:38:27 +00001014- Patch #1435422: zlib's compress and decompress objects now have a
1015 copy() method.
1016
Andrew MacIntyre92913322006-06-13 15:04:24 +00001017- Patch #1454481: thread stack size is now tunable at runtime for thread
1018 enabled builds on Windows and systems with Posix threads support.
1019
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001020- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1021 (up to the system limit of 32K characters).
1022
1023- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1024 As a result, these functions now raise WindowsError instead of OSError.
1025
Tim Peters7a822da2006-05-25 21:50:17 +00001026- ``time.clock()`` on Win64 should use the high-performance Windows
1027 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1028 Windows platforms).
1029
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001030- Calling Tk_Init twice is refused if the first call failed as that
1031 may deadlock.
1032
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001033- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1034 accept it without potentially using an uninitialized pointer.
1035
1036- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1037 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1038 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001039
Gregory P. Smith372b5832006-06-05 18:48:21 +00001040- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001041 [pybsddb project SF patch number 1466734]
1042
Gregory P. Smith372b5832006-06-05 18:48:21 +00001043- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1044 parameter is supplied. [SF pybsddb bug #1477863]
1045
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001046- bsddb: the __len__ method of a DB object has been fixed to return correct
1047 results. It could previously incorrectly return 0 in some cases.
1048 Fixes SF bug 1493322 (pybsddb bug 1184012).
1049
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001050- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1051 aborts the db transaction safely when a modifier callback fails.
1052 Fixes SF python patch/bug #1408584.
1053
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001054- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001055 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001056 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1057 database calls that would previously deadlock. [SF python bug #775414]
1058
Vinay Sajip28e57612006-07-01 10:45:20 +00001059- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1066
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001067- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1068 functions.
1069
Martin v. Löwis3798da02006-06-17 18:44:27 +00001070- Patch #812986: Update turtle output even if not tracing.
1071
Vinay Sajip28e57612006-07-01 10:45:20 +00001072- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001073 Tkinter.BaseWidget.
1074
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001075- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1076
Martin v. Löwis337487e2006-06-17 09:15:14 +00001077- Patch #763580: Add name and value arguments to Tkinter variable
1078 classes.
1079
Georg Brandl83cc0d02006-06-14 08:50:03 +00001080- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1081 mime.types file for determining MIME types.
1082
Georg Brandl2605ca82006-06-14 06:08:31 +00001083- Bug #1339007: Shelf objects now don't raise an exception in their
1084 __del__ method when initialization failed.
1085
Martin v. Löwisd8251432006-06-14 05:21:04 +00001086- Patch #1455898: The MBCS codec now supports the incremental mode for
1087 double-byte encodings.
1088
Tim Peters43898b42006-06-14 04:09:25 +00001089- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1090 guarantee that adjacent triples in the return list always describe
1091 non-adjacent blocks. Previously, a pair of matching blocks could end
1092 up being described by multiple adjacent triples that formed a partition
1093 of the matching pair.
1094
Greg Ward0e0c9f42006-06-11 16:24:11 +00001095- Bug #1498146: fix optparse to handle Unicode strings in option help,
1096 description, and epilog.
1097
Greg Wardd1c797e2006-06-11 14:42:41 +00001098- Bug #1366250: minor optparse documentation error.
1099
Greg Ward7f547402006-06-11 00:40:49 +00001100- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1101 clarify docs.
1102
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001103- The wsgiref package has been added to the standard library.
1104
Nick Coghlan676725d2006-06-08 13:54:49 +00001105- The functions update_wrapper() and wraps() have been added to the functools
1106 module. These make it easier to copy relevant metadata from the original
1107 function when writing wrapper functions.
1108
Tim Petersd6a9eef2006-06-05 01:48:21 +00001109- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1110 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001111
Martin v. Löwis3f767792006-06-04 19:36:28 +00001112- Patch #1359618: Speed up charmap encoder by using a trie structure
1113 for lookup.
1114
Tim Petersd609b1a2006-06-02 23:22:51 +00001115- The functions in the ``pprint`` module now sort dictionaries by key
1116 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1117 if and only if its display required more than one line, although that
1118 wasn't documented. The new behavior increases predictability; e.g.,
1119 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1120
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001121- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1122 (thanks for J. J. Lee).
1123
Georg Brandl2b330372006-05-28 20:23:12 +00001124- Patch #1496206: improve urllib2 handling of passwords with respect to
1125 default HTTP and HTTPS ports.
1126
George Yoshidaf3c65de2006-05-28 16:39:09 +00001127- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1128
Bob Ippolito7298f272006-05-23 18:43:47 +00001129- Patch #1281707: speed up gzip.readline.
1130
Georg Brandlb89316f2006-05-17 15:51:16 +00001131- Patch #1180296: Two new functions were added to the locale module:
1132 format_string() to get the effect of "format % items" but locale-aware,
1133 and currency() to format a monetary number with currency sign.
1134
Georg Brandle3a25832006-05-17 14:56:04 +00001135- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1136 and several features added, such as speed and geometry control.
1137
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001138- Patch #1488881: add support for external file objects in bz2 compressed
1139 tarfiles.
1140
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001141- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1142 stdout arguments, making it possible to redirect input and output
1143 for remote debugging.
1144
1145- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1146 a couple of issues, notably handling of long file names using the
1147 GNU LONGNAME extension.
1148
1149- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1150 new flag when ``name`` is already the name of an option flag.
1151
1152- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1153 package.
1154
1155- Patch #1472854: make the rlcompleter.Completer class usable on non-
1156 UNIX platforms.
1157
1158- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1159
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001160- Bug #1472827: correctly escape newlines and tabs in attribute values in

1196Core and builtins
1197-----------------
1198
Thomas Heller1b046642006-04-18 18:51:06 +00001199- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1200 by converting these apis from macros into exported functions again:
1201
1202 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1203 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1204 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1206 PyRun_String Py_CompileString
1207
Martin v. Löwis45294a92006-04-18 06:24:08 +00001208- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1209
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001210- All uses of PyStructSequence_InitType have been changed to initialize
1211 the type objects only once, even if the interpreter is initialized
1212 multiple times.
1213
Neal Norwitz61546162006-04-14 05:20:28 +00001214- Bug #1454485, array.array('u') could crash the interpreter. This was
1215 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1216 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1217
1218- Py_UNICODE is unsigned. It was always documented as unsigned, but
1219 due to a bug had a signed value in previous versions.
1220
Tim Peters3a5e8b12006-04-11 01:44:07 +00001221- Patch #837242: ``id()`` of any Python object always gives a positive
1222 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1223 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001224 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001225 ``id()`` of an object:

Tim Peters3a5e8b12006-04-11 01:44:07 +00001227 def __hash__(self):
1228 return id(self) # WRONG
1229
1230 because a hash result must be a (short) Python int but it was always
1231 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001232 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001233 was always usable as a hash value before this patch. That's no longer
1234 necessarily so.
1235
1236- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001237 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001238 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001239 #1454844)
1240
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001241- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1242 involving generators that have paused outside of any ``try`` or ``with``
1243 blocks. (In 2.5a1, a paused generator that was part of a reference
1244 cycle could not be garbage collected, regardless of whether it was
1245 paused in a ``try`` or ``with`` block.)

1252
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001253- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1254 fails with an error condition.
1255
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001256- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1257
1258- Bug #1117761: bsddb.*open() no longer raises an exception when using
1259 the cachesize parameter.
1260
1261- Bug #1149413: bsddb.*open() no longer raises an exception when using
1262 a temporary db (file=None) with the 'n' flag to truncate on open.
1263
1264- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1265 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001266
Armin Rigoa9017c32006-04-19 11:50:27 +00001267- Patch #1062014: AF_UNIX sockets under Linux have a special
1268 abstract namespace that is now fully supported.
1269

1271-------
1272
Peter Astrand7d1d4362006-07-14 14:04:45 +00001273- Bug #1223937: subprocess.CalledProcessError reports the exit status
1274 of the process using the returncode attribute, instead of
1275 abusing errno.
1276
Tim Peters711bf302006-04-25 03:31:36 +00001277- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1278 a doctest to be skipped (the code is not run, and the expected output
1279 or exception is ignored).
1280
Nick Coghlanda2268f2006-04-24 04:37:15 +00001281- Fixed contextlib.nested to cope with exceptions being raised and
1282 caught inside exit handlers.
1283
Greg Wardab05edc2006-04-23 03:47:58 +00001284- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1285 hex, octal, or binary; add ``append_const`` action; keep going if
1286 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1287 added ``epilog`` for better help generation).
1288
Tim Peters21fbd572006-04-21 21:18:10 +00001289- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1290 called from a thread spawned as a side effect of importing a module.
1291
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001292- The pydoc module now supports documenting packages contained in
1293 .zip or .egg files.
1294
1295- The pkgutil module now has several new utility functions, such
1296 as ``walk_packages()`` to support working with packages that are either
1297 in the filesystem or zip files.
1298
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001299- The mailbox module can now modify and delete messages from
1300 mailboxes, in addition to simply reading them. Thanks to Gregory
1301 K. Johnson for writing the code, and to the 2005 Google Summer of
1302 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001303
Tim Petersc7605f22006-04-17 21:12:33 +00001304- The ``__del__`` method of class ``local`` in module ``_threading_local``
1305 returned before accomplishing any of its intended cleanup.

1312
Anthony Baxtere29002c2006-04-12 12:07:31 +00001313- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1314 Windows. Bug #1469163.
1315
Phillip J. Eby47032112006-04-11 01:07:43 +00001316- The warnings, linecache, inspect, traceback, site, and doctest modules
1317 were updated to work correctly with modules imported from zipfiles or
1318 via other PEP 302 __loader__ objects.
1319

1326
Skip Montanaro262fb922006-04-21 02:31:07 +00001327- The pstats.Stats class accepts an optional stream keyword argument to
1328 direct output to an alternate file-like object.
1329
Anthony Baxter51bcb682006-04-05 14:51:42 +00001330Build
1331-----
1332
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001333- The Makefile now has a reindent target, which runs reindent.py on
1334 the library.
1335
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001336- Patch #1470875: Building Python with MS Free Compiler
1337
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001338- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001339
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001340- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1341 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001342 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001343 CXX from --with-cxx-main, see description in README.
1344
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001345- Patch #1429775: Link extension modules with the shared libpython.
1346
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001347- Fixed a libffi build problem on MIPS systems.
1348
Tim Peters8931ff12006-05-13 23:28:20 +00001349- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1350 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1351 and "%zu" for unsigned integers of type ``size_t``.
1352
Anthony Baxter51bcb682006-04-05 14:51:42 +00001353Tests
1354-----
1355
Nick Coghlanda2268f2006-04-24 04:37:15 +00001356- test_contextlib now checks contextlib.nested can cope with exceptions
1357 being raised and caught inside exit handlers.
1358
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001359- test_cmd_line now checks operation of the -m and -c command switches
1360
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001361- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1362 it separately and by hand. It also wasn't cleaning up its changes to
1363 the current Decimal context.
1364
Thomas Woutersabd08882006-04-26 15:53:30 +00001365- regrtest.py now has a -M option to run tests that test the new limits of
1366 containers, on 64-bit architectures. Running these tests is only sensible
1367 on 64-bit machines with more than two gigabytes of memory. The argument
1368 passed is the maximum amount of memory for the tests to use.

1377-------------
1378
Tim Petersb06d28c2006-05-12 01:57:59 +00001379- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1380
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001381- PEP 343: Added Context Types section to the library reference
1382 and attempted to bring other PEP 343 related documentation into
1383 line with the implementation and/or python-dev discussions.
1384
Tim Peters8dc73d22006-04-24 02:03:16 +00001385- Bug #1337990: clarified that ``doctest`` does not support examples
1386 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001389What's New in Python 2.5 alpha 1?
1390=================================
1391
Anthony Baxterebed3f62006-04-03 15:03:44 +00001392*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001393
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001394Core and builtins
1395-----------------
1396
Nick Coghlan43832302006-04-23 17:04:07 +00001397- PEP 338: -m command line switch now delegates to runpy.run_module
1398 allowing it to support modules in packages and zipfiles
1399
Martin v. Löwisc661b882006-04-20 04:54:23 +00001400- On Windows, .DLL is not an accepted file name extension for
1401 extension modules anymore; extensions are only found if they
1402 end in .PYD.
1403
Martin v. Löwisea62d252006-04-03 10:56:49 +00001404- Bug #1421664: sys.stderr.encoding is now set to the same value as
1405 sys.stdout.encoding.
1406
Neal Norwitz92e212f2006-04-03 04:48:37 +00001407- __import__ accepts keyword arguments.
1408
Georg Brandlccadf842006-03-31 18:54:53 +00001409- Patch #1460496: round() now accepts keyword arguments.
1410
Anthony Baxter262c00a2006-03-30 10:53:17 +00001411- Fixed bug #1459029 - unicode reprs were double-escaped.
1412
Hye-Shik Changd478f342006-03-23 12:32:36 +00001413- Patch #1396919: The system scope threads are reenabled on FreeBSD
1414 5.4 and later versions.
1415
Neal Norwitze98ccf62006-03-23 05:39:47 +00001416- Bug #1115379: Compiling a Unicode string with an encoding declaration
1417 now gives a SyntaxError.
1418
Georg Brandlabd1ff82006-03-18 07:59:59 +00001419- Previously, Python code had no easy way to access the contents of a
1420 cell object. Now, a ``cell_contents`` attribute has been added
1421 (closes patch #1170323).
1422
Tim Peterscf79aac2006-03-16 01:14:46 +00001423- Patch #1123430: Python's small-object allocator now returns an arena to
1424 the system ``free()`` when all memory within an arena becomes unused
1425 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1426 freed. Some applications will see a drop in virtual memory size now,
1427 especially long-running applications that, from time to time, temporarily
1428 use a large number of small objects. Note that when Python returns an
1429 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001430 platform C library will in turn return that memory to the operating system.
1431 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001432 appears to be effective at least on Microsoft C and gcc-based systems.
1433 Thanks to Evan Jones for hard work and patience.
1434
Georg Brandl533ff6f2006-03-08 18:09:27 +00001435- Patch #1434038: property() now uses the getter's docstring if there is
1436 no "doc" argument given. This makes it possible to legitimately use
1437 property() as a decorator to produce a read-only property.
1438
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001439- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1440 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1441 of requiring an int or long in slicing and a few other contexts, enabling
1442 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1443
Neal Norwitz995acdf2006-03-07 05:01:00 +00001444- Fixed various bugs reported by Coverity's Prevent tool.
1445
Brett Cannonbf364092006-03-01 04:25:17 +00001446- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1447 new exception base class, BaseException, which has a new message attribute.
1448 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1449 Raising a string exception now raises a DeprecationWarning.
1450
Thomas Woutersfb609f42006-02-28 16:37:25 +00001451- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1452 explicitly relative, using 'from .module import name' to mean 'from the same
1453 package as this module is in. Imports without dots still default to the
1454 old relative-then-absolute, unless 'from __future__ import
1455 absolute_import' is used.
1456
Brett Cannona7446e32006-02-27 23:39:10 +00001457- Properly check if 'warnings' raises an exception (usually when a filter set
1458 to "error" is triggered) when raising a warning for raising string
1459 exceptions.
1460
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001461- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001462 The name was removed from Include/code.h.
1463
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001464- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001465
Guido van Rossum1968ad32006-02-25 22:38:04 +00001466- Patch 1433928:
1467 - The copy module now "copies" function objects (as atomic objects).
1468 - dict.__getitem__ now looks for a __missing__ hook before raising
1469 KeyError.
1470
Tim Peters84ef21c2006-02-28 20:39:06 +00001471- PEP 343: with statement implemented. Needs ``from __future__ import
1472 with_statement``. Use of 'with' as a variable will generate a warning.
1473 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001474 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001475 The following objects have __context__ methods:
1476 - The built-in file type.
1477 - The thread.LockType type.
1478 - The following types defined by the threading module:
1479 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1480 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001481
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001482- Fix the encodings package codec search function to only search
1483 inside its own package. Fixes problem reported in patch #1433198.
1484
1485 Note: Codec packages should implement and register their own
1486 codec search function. PEP 100 has the details.
1487
Tim Peters9ea89d22006-06-04 03:26:02 +00001488- PEP 353: Using ``Py_ssize_t`` as the index type.
1489
1490- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1491 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1492 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1493 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1494 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001495
Neal Norwitzfc76d632006-01-10 06:03:13 +00001496- Patch #1400181, fix unicode string formatting to not use the locale.
1497 This is how string objects work. u'%f' could use , instead of .
1498 for the decimal point. Now both strings and unicode always use periods.
1499
Neal Norwitz671b9e32006-01-09 07:07:12 +00001500- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1501 configure would break checking curses.h.
1502
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001503- Bug #959576: The pwd module is now builtin. This allows Python to be
1504 built on UNIX platforms without $HOME set.
1505
Neal Norwitzc10978f2005-12-19 06:07:16 +00001506- Bug #1072182, fix some potential problems if characters are signed.
1507
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001508- Bug #889500, fix line number on SyntaxWarning for global declarations.
1509
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001510- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1511
Neal Norwitze7214a12005-12-18 05:03:17 +00001512- Support for converting hex strings to floats no longer works.
1513 This was not portable. float('0x3') now raises a ValueError.

Barry Warsaw2a38a862005-12-18 01:27:35 +00001515- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001516 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001517 is now displayed in interactive prompt banner.
1518
Georg Brandlfa166682005-12-17 21:45:17 +00001519- Implementation of PEP 341 - Unification of try/except and try/finally.
1520 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001521 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001522
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001523- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1524 now encodes backslash correctly.
1525
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001526- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1527
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001528- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001529 and long longs.
1530
Neal Norwitz67715f02005-11-09 06:59:35 +00001531- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001532 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001533 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001534
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001535- Replaced most Unicode charmap codecs with new ones using the
1536 new Unicode translate string feature in the builtin charmap
1537 codec; the codecs were created from the mapping tables available
1538 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1539 encodings now include a mapping for the Apple logo)
1540
Tim Peterse3547fd2005-12-16 23:13:57 +00001541- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001542
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001543- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001544
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001545- A new AST parser implementation was completed. The abstract
1546 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001547 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001548
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001549- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001550 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1551
Neal Norwitz708e51a2005-10-03 04:48:15 +00001552- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1553
Neal Norwitz11bd1192005-10-03 00:54:56 +00001554- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1555 Provide a warning when a directory is passed on the command line.
1556
Neal Norwitz40d37812005-10-02 01:48:49 +00001557- Fix segfault with invalid coding.
1558
1559- SF bug #772896: unknown encoding results in MemoryError.
1560
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001561- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001562 supported a __len__() method which evaluated to False when the iterator
1563 was empty.
1564
Guido van Rossum630db602005-09-20 18:49:54 +00001565- On 64-bit platforms, when __len__() returns a value that cannot be
1566 represented as a C int, raise OverflowError.
1567
Skip Montanarof8948ca2005-09-19 03:54:46 +00001568- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001569 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001570
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001571- SF bug #893549: parsing keyword arguments was broken with a few format
1572 codes.
1573
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001574- Changes donated by Elemental Security to make it work on AIX 5.3
1575 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1576 bug #105470: test_pwd fails on 64bit system (Opteron).
1577
Guido van Rossum539c6622005-09-14 17:49:54 +00001578- Changes donated by Elemental Security to make it work on HP-UX 11 on
1579 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1580
Georg Brandl4550b8d2005-08-26 06:43:52 +00001581- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001582 (fixes bug #1119418).
1583
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001584- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1585
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001586- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1587 exceptions that cause a function to exit.
1588
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001589- The implementation of set() and frozenset() was revised to use its
1590 own internal data structure. Memory consumption is reduced by 1/3
1591 and there are modest speed-ups as well. The API is unchanged.
1592
Tim Petersde7990b2005-07-17 23:45:23 +00001593- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1594
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001595- SF bug #1229429: PyObject_CallMethod failed to decrement some
1596 reference counts in some error exit cases.
1597
Tim Petersecc6e6a2005-07-10 22:30:55 +00001598- SF bug #1185883: Python's small-object memory allocator took over
1599 a block managed by the platform C library whenever a realloc specified
1600 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001601 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001602 portable way to copy data from the C-managed block into Python's
1603 small-object space without risking a memory fault. Python's small-object
1604 realloc now leaves such blocks under the control of the platform C
1605 realloc.
1606
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001607- SF bug #1232517: An overflow error was not detected properly when
1608 attempting to convert a large float to an int in os.utime().
1609
Raymond Hettinger3296e692005-06-29 23:29:56 +00001610- SF bug #1224347: hex longs now print with lowercase letters just
1611 like their int counterparts.
1612
Michael W. Hudson188d4362005-06-20 16:52:57 +00001613- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1614 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1615 interpreter states; back out that fix and do a better job (see
1616 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1617 for a longer write-up of the problem).
1618
Michael W. Hudsondf888462005-06-03 14:41:55 +00001619- SF patch #1180995: marshal now uses a binary format by default when
1620 serializing floats.
1621
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001622- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1623 the routines that promise to produce IEEE 754 binary representations
1624 of floats now simply copy bytes around.
1625
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001626- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1627 278.
1628
Brett Cannonc3647ac2005-04-26 03:45:26 +00001629- patch #1109424: int, long, float, complex, and unicode now check for the
1630 proper magic slot for type conversions when subclassed. Previously the
1631 magic slot was ignored during conversion. Semantics now match the way
1632 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001633 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001634 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001635 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001636
Barry Warsawc8d907c2005-04-19 23:43:40 +00001637- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1638 NULL, now raise an AttributeError when attempting to set or delete the
1639 attribute. Previously a TypeError was raised, but this was inconsistent
1640 with the equivalent pure-Python implementation.
1641
Michael W. Hudson774479c2005-04-18 08:46:17 +00001642- It is now safe to call PyGILState_Release() before
1643 PyEval_InitThreads() (note that if there is reason to believe there
1644 are multiple threads around you still must call PyEval_InitThreads()
1645 before using the Python API; this fix is for extension modules that
1646 have no way of knowing if Python is multi-threaded yet).
1647
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001648- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1649 disabled caused a crash.
1650
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001651- Bug #1165306: instancemethod_new allowed the creation of a method
1652 with im_class == im_self == NULL, which caused a crash when called.
1653
Tim Petersecc6e6a2005-07-10 22:30:55 +00001654- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001655 fixes the crash seen in bug #1165761
1656
Raymond Hettinger96229b12005-03-11 06:49:40 +00001657- Added two new builtins, any() and all().
1658
Brett Cannon409d8f22005-03-05 06:47:57 +00001659- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001660 (e.g., ``class C(): pass`` is no longer a syntax error).
1661 Patch #1176012 added support to the 'parser' module and 'compiler' package
1662 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001663
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001664- Patch #1115086: Support PY_LONGLONG in structmember.
1665
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001666- Bug #1155938: new style classes did not check that __init__() was
1667 returning None.
1668
Tim Petersecc6e6a2005-07-10 22:30:55 +00001669- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001670 ('\') with a specific error message.
1671
Martin v. Löwisff232d72005-03-03 09:24:38 +00001672- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1673
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001674- Bug #1124295: the __name__ attribute of file objects was
1675 inadvertently made inaccessible in restricted mode.
1676
Tim Petersecc6e6a2005-07-10 22:30:55 +00001677- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001678 an ferror() call.
1679
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001680- min() and max() now support key= arguments with the same meaning as in
1681 list.sort().
1682
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001683- The peephole optimizer now performs simple constant folding in expressions:
1684 (2+3) --> (5).
1685
Raymond Hettingera422c342005-01-11 03:03:27 +00001686- set and frozenset objects can now be marshalled. SF #1098985.
1687
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001688- Bug #1077106: Poor argument checking could cause memory corruption
1689 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001690
Jeremy Hyltonab630502005-02-04 18:44:06 +00001691- The parser did not complain about future statements in illegal
1692 positions. It once again reports a syntax error if a future
1693 statement occurs after anything other than a doc string.
1694
Neil Schemenauercf52c072005-08-12 17:34:58 +00001695- Change the %s format specifier for str objects so that it returns a
1696 unicode instance if the argument is not an instance of basestring and
1697 calling __str__ on the argument returns a unicode instance.
1698
Tim Petersf4e69282006-02-27 17:15:31 +00001699- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1700 current thread state when the auto-GIL-state machinery knows about
1701 it (since the thread state is being deleted, continuing to remember it
1702 can't help, but can hurt if another thread happens to get created with
1703 the same thread id).
1704
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001705Extension Modules
1706-----------------
1707
Georg Brandl43f08a82006-03-31 18:01:16 +00001708- Patch #1380952: fix SSL objects timing out on consecutive read()s

1711
Anthony Baxterfa869072006-03-20 05:21:58 +00001712- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1713 In addition, the existing ulaw code was updated.
1714
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001715- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001716 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001717
Neal Norwitz10be10c2006-03-16 06:50:13 +00001718- Everything under lib-old was removed. This includes the following modules:
1719 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001720 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001721 util, whatsound, whrandom, zmod
1722
1723- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1724
1725- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001726 is deprecated. The undocumented re.engine variable no longer exists.
1727
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001728- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1729 SS2 (single-shift 2) escape sequences correctly.
1730
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001731- The unicodedata module was updated to the 4.1 version of the Unicode
1732 database. The 3.2 version is still available as unicodedata.db_3_2_0
1733 for applications that require this specific version (such as IDNA).
1734
Neal Norwitzb62c4332006-03-04 18:35:47 +00001735- The timing module is no longer built by default. It was deprecated
1736 in PEP 4 in Python 2.0 or earlier.
1737
Guido van Rossum1968ad32006-02-25 22:38:04 +00001738- Patch 1433928: Added a new type, defaultdict, to the collections module.
1739 This uses the new __missing__ hook behavior added to dict (see above).
1740
Georg Brandldbd83392006-02-20 09:42:33 +00001741- Bug #854823: socketmodule now builds on Sun platforms even when
1742 INET_ADDRSTRLEN is not defined.
1743
Georg Brandlf4f44152006-02-18 22:29:33 +00001744- Patch #1393157: os.startfile() now has an optional argument to specify
1745 a "command verb" to invoke on the file.
1746
Neal Norwitz082b2df2006-02-07 07:04:46 +00001747- Bug #876637, prevent stack corruption when socket descriptor
1748 is larger than FD_SETSIZE.
1749
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001750- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1751 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1752 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1753
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001754- Patch #1422385: The nis module now supports access to domains other
1755 than the system default domain.
1756
Martin v. Löwis14694662006-02-03 12:54:16 +00001757- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1758 are reported, the limit on path name lengths is removed, and stat reports
1759 WindowsError now (instead of OSError).
1760
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001761- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1762
Neal Norwitz62a21122006-01-25 05:21:55 +00001763- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1764 before the env.
1765
Martin v. Löwis11017b12006-01-14 18:12:57 +00001766- Patch #1103116: Basic AF_NETLINK support.
1767
Neal Norwitz3b4fff82006-01-11 08:54:45 +00001768- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
1769
Neal Norwitz88bbd732006-01-10 07:05:44 +00001770- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
1771 Also fix ungetmouse() which did not accept arguments properly.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001895- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1896 been renamed to have only a single underscore prefix. This was done to
1897 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001898
Nick Coghlan43832302006-04-23 17:04:07 +00001899- PEP 338: new module runpy defines a run_module function to support
1900 executing modules which provide access to source code or a code object
1901 via the PEP 302 import mechanisms.
1902
Anthony Baxter93f5b932006-04-03 08:05:07 +00001903- The email module's parsedate_tz function now sets the daylight savings
1904 flag to -1 (unknown) since it can't tell from the date whether it should

1911 in attribute values.
1912
Anthony Baxterc51ee692006-04-01 00:57:31 +00001913- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001914 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001915 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001916 module will not be built.
1917
Tim Petersc17976e2006-04-01 00:26:53 +00001918- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1919 aren't officially supported here, and trying to use them will probably
1920 raise an exception some day. But dicts have been allowed, and "mostly
1921 worked", so support for them won't go away without warning.
1922
Georg Brandl338ef7d2006-03-31 18:42:16 +00001923- Bug #1445068: getpass.getpass() can now be given an explicit stream
1924 argument to specify where to write the prompt.

1941
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001942- email 4.0 package now integrated. This is largely the same as the email 3.0
1943 package that was included in Python 2.3, except that PEP 8 module names are
1944 now used (e.g. mail.message instead of email.Message). The MIME classes
1945 have been moved to a subpackage (e.g. email.mime.text instead of
1946 email.MIMEText). The old names are still supported for now. Several
1947 deprecated Message methods have been removed and lots of bugs have been
1948 fixed. More details can be found in the email package documentation.
1949
Walter Dörwald40108c92006-03-27 08:15:44 +00001950- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1951 (a subclass of tuple) that provides incremental decoders and encoders
1952 (a way to use stateful codecs without the stream API). Python functions
1953 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1954 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1955 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001957- Patch #1359365: Calling next() on a closed StringIO.String object raises
1958 a ValueError instead of a StopIteration now (like file and cString.String do).
1959 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1960 called before (like file and StringIO.StringIO do).

2035 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2036 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2037 Ronald L. Rivest offered this advice for Python:
2038
2039 "The consensus of researchers in this area (at least as
2040 expressed at the NIST Hash Function Workshop 10/31/05),
2041 is that SHA-256 is a good choice for the time being, but
2042 that research should continue, and other alternatives may
2043 arise from this research. The larger SHA's also seem OK."

2138 Bug #1224621.
2139
Raymond Hettinger68c04532005-06-10 11:05:19 +00002140- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002141 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002142 the generate_tokens() function now accepts a callable argument that
2143 terminates by raising StopIteration.
2144
Georg Brandl9166e1a2005-06-04 09:20:03 +00002145- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2153 class at all.
2154
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002155- distutils.commands.upload was added to support uploading distribution

2160
Raymond Hettinger267b8682005-03-27 10:47:39 +00002161- decimal operator and comparison methods now return NotImplemented
2162 instead of raising a TypeError when interacting with other types. This
2163 allows other classes to implement __radd__ style methods and have them
2164 work as expected.
2165
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002166- Bug #1163325: Decimal infinities failed to hash. Attempting to

2168
Tim Petersecc6e6a2005-07-10 22:30:55 +00002169- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2203
Guido van Rossumd0641422005-02-03 15:01:24 +00002204- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2205 disables recursive traversal through instance attributes, which can
2206 be exploited in various ways.
2207
Tim Peterse3547fd2005-12-16 23:13:57 +00002208- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002209 flags on the HTTP listening socket.
2210

2220
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002221- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2222
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002223- Enhancements to the csv module:
2224
2225 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002226 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002227 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002228 + Dialect parameter parsing has been re-implemented to improve error
2229 reporting.
2230 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2231 dictates.
2232 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002233 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002234 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002235 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2236 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002237 + reader now allows \r characters to be quoted (previously it only allowed
2238 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002239 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002240 + Dialect classes passed to the module are no longer instantiated by
2241 the module before being parsed (the former validation scheme required
2242 this, but the mechanism was unreliable).
2243 + The dialect registry now contains instances of the internal
2244 C-coded dialect type, rather than references to python objects.
2245 + the internal c-coded dialect type is now immutable.
2246 + register_dialect now accepts the same keyword dialect specifications
2247 as the reader and writer, allowing the user to register dialects
2248 without first creating a dialect class.
2249 + a configurable limit to the size of parsed fields has been added -
2250 previously, an unmatched quote character could result in the entire
2251 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002252 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002253 the parser field size limit (returning the former limit). The initial
2254 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002255 + A line_num attribute has been added to the reader object, which tracks
2256 the number of lines read from the source iterator. This is not
2257 the same as the number of records returned, as records can span
2258 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002259 + reader and writer objects were not being registered with the cyclic-GC.
2260 This has been fixed.
2261
Brett Cannone6539c42005-01-08 02:43:53 +00002262- _DummyThread objects in the threading module now delete self.__block that is
2263 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2264 lock primitives tend to be limited in number and thus should not be wasted on
2265 a _DummyThread object. Fixes bug #1089632.
2266
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002267- The imghdr module now detects Exif files.
2268
Raymond Hettinger6065d322004-12-20 23:51:53 +00002269- StringIO.truncate() now correctly adjusts the size attribute.
2270 (Bug #951915).
2271
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002272- locale.py now uses an updated locale alias table (built using
2273 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2274 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002275 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002276
Raymond Hettinger3557f422004-12-07 12:02:02 +00002277- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2278
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002279- the pickle module no longer accepts the deprecated None option in the
2280 args tuple returned by __reduce__().
2281
Brett Cannon84667c02004-12-07 03:25:18 +00002282- optparse now optionally imports gettext. This allows its use in setup.py.
2283
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002284- the pickle module no longer uses the deprecated bin parameter.
2285
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002286- the shelve module no longer uses the deprecated binary parameter.
2287
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002288- the pstats module no longer uses the deprecated ignore() method.
2289
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002290- the filecmp module no longer uses the deprecated use_statcache argument.
2291
Raymond Hettinger664347b2004-12-04 21:21:53 +00002292- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2293 extended or overridden by subclasses. Formerly, the subclassed method would
2294 be ignored by the rest of the module. (Bug #1078905).
2295
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002296- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002297 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002298
Walter Dörwald36733692004-12-22 12:50:50 +00002299- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2300 once when a size argument is given. This prevents a buffer overflow in the
2301 tokenizer with very long source lines.
2302
Barry Warsaw538561e2006-01-01 21:48:54 +00002303- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2304 immediately after creating the object, without any intervening
2305 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002306
Skip Montanaro05885812005-01-16 20:48:27 +00002307- The reconvert.quote function can now emit triple-quoted strings. The
2308 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002309
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002310- ``UserString.MutableString`` now supports negative indices in
2311 ``__setitem__`` and ``__delitem__``
2312
Greg Ward40407942005-03-05 02:53:17 +00002313- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2314 correctly.
2315
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002316- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2317 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2318 character even if the user has passed a size parameter to get a proper
2319 line ending. Remove the special handling of a "\r\n" that has been split
2320 between two lines.
2321
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002322- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2323 about illegal code points. The codec now supports PEP 293 style error
2324 handlers.
2325
Walter Dörwald78a78b02005-09-01 12:04:29 +00002326- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002327 from the input stream, so that the output is a byte string in the correct
2328 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002329
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002330- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2331 considering it exactly like a '*'.
2332
Walter Dörwald007f8df2005-10-09 19:42:27 +00002333- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2334 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002335
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002336- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2337
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002338- Patch #1413711: Certain patterns of differences were making difflib
2339 touch the recursion limit.
2340
Walter Dörwald58917a62006-03-31 15:26:22 +00002341- Bug #947906: An object oriented interface has been added to the calendar
2342 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002343 called as a script (e.g. via ``python -mcalendar``). Localized month and
2344 weekday names can be ouput (even if an exotic encoding is used) using
2345 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002347Build
2348-----
2349
Neal Norwitz602d3392006-03-31 08:21:40 +00002350- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2351 by using -mieee gcc option.
2352

2354
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002355- Build support for Win64-AMD64 was added.
2356
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002357- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2358
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002359- Patch #881820: look for openpty and forkpty also in libbsd.
2360
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002361- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2362 The zlib module is now builtin on Windows.
2363
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002364- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2365
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002366- Bug #1189330: configure did not correctly determine the necessary
2367 value of LINKCC if python was built with GCC 4.0.
2368
Trent Mick8321b422005-07-26 02:29:21 +00002369- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2370 vulnerability in zlib 1.2.1 and 1.2.2.
2371
Brett Cannon08cd5982005-04-24 22:26:38 +00002372- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2373 flags that change binary compatibility. Changes were also made to
2374 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002375 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002376
Bob Ippolitoed233462005-03-29 13:47:59 +00002377- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2378 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2379 no longer exists). This configure patch makes things right.
2380
Martin v. Löwise2713be2005-03-08 15:03:08 +00002381- Bug #1158607: Build with --disable-unicode again.
2382
Brett Cannon46d96232005-02-16 00:07:19 +00002383- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2384 defined. Discovered as a result of not being able to build on OS X.
2385
Brett Cannon516592f2004-12-07 00:42:59 +00002386- setup.py now uses the directories specified in LDFLAGS using the -L option
2387 and in CPPFLAGS using the -I option for adding library and include
2388 directories, respectively, for compiling extension modules against. This has
2389 led to the core being compiled using the values in CPPFLAGS. It also removes
2390 the need for the special-casing of both DarwinPorts and Fink for darwin since
2391 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2392 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2393 Fink, ``-I/opt/local/include`` for DarwinPorts).
2394
Brett Cannon43802422005-02-10 20:48:03 +00002395- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2396 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2397 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2398 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002400C API
2401-----
2402
Tim Petersc9d78aa2006-03-26 23:27:58 +00002403- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2404 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2405 is obtained via the ``PyObject_`` family, it must be released via the
2406 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2407 always been officially true, but when Python's small-object allocator was
2408 introduced, an attempt was made to cater to a few extension modules
2409 discovered at the time that obtained memory via ``PyObject_New`` but
2410 released it via ``PyMem_DEL``. It's years later, and if such code still
2411 exists it will fail now (probably with segfaults, but calling wrong
2412 low-level memory management functions can yield many symptoms).
2413
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002414- Added a C API for set and frozenset objects.
2415
Raymond Hettinger66517482004-12-03 11:45:13 +00002416- Removed PyRange_New().
2417
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002418- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2419 mapping argument now. This string is used as a mapping table. Byte values
2420 greater than the length of the string and 0xFFFE are treated as undefined
2421 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002427- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002428
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002429- Patch #1276356: New resource "urlfetch" is implemented. This enables
2430 even impatient people to run tests that require remote files.
