Neal Norwitz56423e52006-08-13 18:11:08 +0000320
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000321 Instead, the equal (==) and unequal (!=) comparison operators will
322 now issue a UnicodeWarning and interpret the two objects as
323 unequal. The UnicodeWarning can be filtered as desired using
324 the warning framework, e.g. silenced completely, turned into an
325 exception, logged, etc.
326
327 Note that compare operators other than equal and unequal will still
328 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000329
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000330- Fix segfault when doing string formatting on subclasses of long.
331
332- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
333 with new-style classes.
334
335- Fix bug related to __len__ functions returning negative values with
336 classic classes.
337
338- Patch #1538606, Fix __index__() clipping. There were some problems
339 discovered with the API and how integers that didn't fit into Py_ssize_t
340 were handled. This patch attempts to provide enough alternatives
341 to effectively use __index__.
342
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000343- Bug #1536021: __hash__ may now return long int; the final hash
344 value is obtained by invoking hash on the long int.
345
Thomas Hellerab1049c2006-08-08 17:37:00 +0000346- Bug #1536786: buffer comparison could emit a RuntimeWarning.
347
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000348- Bug #1535165: fixed a segfault in input() and raw_input() when
349 sys.stdin is closed.
350
Thomas Heller74d36f02006-08-04 18:17:40 +0000351- On Windows, the PyErr_Warn function is now exported from
352 the Python dll again.
353
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000354- Bug #1191458: tracing over for loops now produces a line event
355 on each iteration. Fixing this problem required changing the .pyc
356 magic number. This means that .pyc files generated before 2.5c1
357 will be regenerated.
358
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000359- Bug #1333982: string/number constants were inappropriately stored
360 in the byte code and co_consts even if they were not used, ie
361 immediately popped off the stack.
362
Georg Brandle9462c72006-08-04 18:03:37 +0000363- Fixed a reference-counting problem in property().

366Library
367-------
368
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000369- Fix a bug in the ``compiler`` package that caused invalid code to be
370 generated for generator expressions.
371
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000372- The distutils version has been changed to 2.5.0. The change to
373 keep it programmatically in sync with the Python version running
374 the code (introduced in 2.5b3) has been reverted. It will continue
375 to be maintained manually as static string literal.
376
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000377- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000378 and this cannot be converted to the required C type, an exception is
379 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000380 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000381
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000382- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000383 an exception.
384
Tim Peterscbdd3502006-09-05 01:47:53 +0000385- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000386 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000387 workarounds for clocks with low resolution, to stop the code yielding
388 duplicate UUIDs.
389
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000390- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
391 before raising SystemExit, allowing IDLE to honor quit() and exit().
392
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000393- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
394
Georg Brandl7a1af772006-08-14 21:55:28 +0000395- Patch #1536071: trace.py should now find the full module name of a
396 file correctly even on Windows.
397
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000398- logging's atexit hook now runs even if the rest of the module has
399 already been cleaned up.
400
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000401- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000403- Bug #1531405, format_exception no longer raises an exception if
404 str(exception) raised an exception.
405
Neil Schemenauer06ded092006-08-04 16:20:30 +0000406- Fix a bug in the ``compiler`` package that caused invalid code to be

418 raises the correct exceptions.
419
Thomas Heller1ce433e2006-08-14 16:20:04 +0000420- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
421 '-no-stack-protector' compiler flag for OpenBSD has been removed.
422
Thomas Heller86720042006-08-14 11:17:48 +0000423- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
424 uses the _as_parameter_ attribute when objects are passed to foreign
425 function calls. The ctypes version number was changed to 1.0.1.
426
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000427- Bug #1530559, struct.pack raises TypeError where it used to convert.
428 Passing float arguments to struct.pack when integers are expected
429 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000455- Bug #1535502, build _hashlib on Windows, and use masm assembler
456 code in OpenSSL.
457
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000458- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

467
Tim Peters4643c2f2006-08-10 22:45:34 +0000468- Bug #1069160. Internal correctness changes were made to
469 ``PyThreadState_SetAsyncExc()``. A test case was added, and
470 the documentation was changed to state that the return value
471 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +0000476
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000477*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000478
479Core and builtins
480-----------------
481
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000482- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000483 returned a long (see PEP 353).
484
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000485- Bug #1515471: string.replace() accepts character buffers again.
486
Neal Norwitz07aadb12006-07-30 06:55:48 +0000487- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
488 This provides the proper warning for struct.pack().
489 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
490
Neal Norwitz0d62a062006-07-30 06:53:31 +0000491- Patch #1531113: Fix augmented assignment with yield expressions.
492 Also fix a SystemError when trying to assign to yield expressions.
493
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000494- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
495 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
496 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
497 excessive filesystem operations during imports.
498
Tim Petersbc24eee2006-07-27 01:14:53 +0000499- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
500 operations on signed longs that are formally undefined by C.
501 Unfortunately, at least one compiler now cares about that, so complicated
502 the code to make that compiler happy again.
503
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000504- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
505
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000506- Patch #1232023: Stop including current directory in search
507 path on Windows.
508
Neal Norwitze1fdb322006-07-21 05:32:28 +0000509- Fix some potential crashes found with failmalloc.
510
Neal Norwitze7563102006-07-17 01:00:16 +0000511- Fix warnings reported by Klocwork's static analysis tool.
512
Neal Norwitz84be93b2006-07-16 01:50:38 +0000513- Bug #1512814, Fix incorrect lineno's when code within a function
514 had more than 255 blank lines.
515
Georg Brandl9dceedb2006-07-12 15:31:17 +0000516- Patch #1521179: Python now accepts the standard options ``--help`` and
517 ``--version`` as well as ``/?`` on Windows.
518
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000519- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000520 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000521 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000522
Tim Peters112aad32006-07-19 00:03:19 +0000523- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000524 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000525 new ``sys._current_frames()`` returns a dictionary with one entry,
526 mapping the faux "thread id" 0 to the current frame.
527
Ronald Oussoren3075e162006-07-25 20:28:55 +0000528- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000529
Ronald Oussoren3075e162006-07-25 20:28:55 +0000530
Neal Norwitza1f10902006-07-12 07:28:29 +0000531Library
532-------
533
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000534- Correction of patch #1455898: In the mbcs decoder, set final=False
535 for stream decoder, but final=True for the decode function.
536
Georg Brandl07fec3a2006-08-01 18:49:24 +0000537- os.urandom no longer masks unrelated exceptions like SystemExit or
538 KeyboardInterrupt.
539
Tim Peters4643c2f2006-08-10 22:45:34 +0000540- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000541 shutil.copytree on Windows
542
Georg Brandle34ac7c2006-07-30 11:07:23 +0000543- Bug #1002398: The documentation for os.path.sameopenfile now correctly
544 refers to file descriptors, not file objects.
545
Tim Peterscbdd3502006-09-05 01:47:53 +0000546- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000547 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000548 #1513611, and probably others.
549
Georg Brandledd9b0d2006-07-29 09:33:26 +0000550- Bug #1441397: The compiler module now recognizes module and function
551 docstrings correctly as it did in Python 2.4.
552
Tim Peters6f681472006-07-27 23:44:37 +0000553- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
554 lost that tests are sorted by name before being run. This rarely
555 matters for well-written tests, but can create baffling symptoms if
556 side effects from one test to the next affect outcomes. ``DocTestFinder``
557 has been changed to sort the list of tests it returns.
558
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000559- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000560 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000561
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000562- Bug #978833: Really close underlying socket in _socketobject.close.
563
Georg Brandldb232dc2006-08-20 13:15:43 +0000564- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
565 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000566
Georg Brandlcf0c1722006-07-26 07:23:32 +0000567- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
568 to recursive calls and call it with the failing package name.
569
Martin v. Löwis0b483032006-07-25 09:53:12 +0000570- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
571
Georg Brandlc13c34c2006-07-24 14:09:56 +0000572- Patch #1515343: Fix printing of deprecated string exceptions with a
573 value in the traceback module.
574
Greg Ward48fae7a2006-07-23 16:05:51 +0000575- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
576
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000577- Patch #1524429: Use repr() instead of backticks in Tkinter again.
578
Brett Cannoncaebe222006-07-18 04:41:36 +0000579- Bug #1520914: Change time.strftime() to accept a zero for any position in its
580 argument tuple. For arguments where zero is illegal, the value is forced to
581 the minimum value that is correct. This is to support an undocumented but
582 common way people used to fill in inconsequential information in the time
583 tuple pre-2.4.
584
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000585- Patch #1220874: Update the binhex module for Mach-O.
586
Barry Warsawb110bad2006-07-21 14:51:07 +0000587- The email package has improved RFC 2231 support, specifically for
588 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
589 (name*0=<blah>) parameter continuations. This may change the types of
590 values returned from email.message.Message.get_param() and friends.
591 Specifically in some cases where non-encoded continuations were used,
592 get_param() used to return a 3-tuple of (None, None, string) whereas now it
593 will just return the string (since non-encoded continuations don't have
594 charset and language parts).
595
596 Also, whereas % values were decoded in all parameter continuations, they are
597 now only decoded in encoded parameter parts.
598
Ronald Oussoren3075e162006-07-25 20:28:55 +0000599- Bug #1517990: IDLE keybindings on MacOS X now work correctly
600
601- Bug #1517996: IDLE now longer shows the default Tk menu when a
602 path browser, class browser or debugger is the frontmost window on MacOS X
603
Barry Warsaw00decd72006-07-27 23:43:15 +0000604- Patch #1520294: Support for getset and member descriptors in types.py,
605 inspect.py, and pydoc.py. Specifically, this allows for querying the type
606 of an object against these built-in types and more importantly, for getting
607 their docstrings printed in the interactive interpreter's help() function.

614 a socket operation on a socket with a timeout, the exception will be
615 caught correctly. Previously, the exception was not caught.
616
Thomas Heller1393d6a2006-07-28 21:43:20 +0000617- Patch #1529514: The _ctypes extension is now compiled on more
618 openbsd target platforms.
619
Tim Peters9cab5932006-07-28 00:30:00 +0000620- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
621 a memory leak, affecting pickles and deep copies.
622
Tim Petersbc24eee2006-07-27 01:14:53 +0000623- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

625
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000626- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
627
Thomas Hellerce049a02006-07-14 17:51:14 +0000628- Patch #1521817: Index range checking on ctypes arrays containing
629 exactly one element enabled again. This allows iterating over these
630 arrays, without the need to check the array size before.
631
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000632- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000633 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000634 /dev/null in certain cases; this is now fixed.
635
Thomas Heller47d7a062006-07-12 08:43:47 +0000636- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
637 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000638
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000639- Because of a misspelled preprocessor symbol, ctypes was always
640 compiled without thread support; this is now fixed.
641
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000642- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
643 methods now allow their database parameter to be None as the
644 sleepycat API allows.
645
Matt Flemingec926502006-07-28 11:27:27 +0000646- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
647 bluetooth API compared with Linux and FreeBSD.
648
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000649Tests
650-----
651
652- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
653 how long the test file should take to play. Now accepts taking 2.93 secs
654 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
655
Georg Brandl4793aa32006-07-28 18:31:39 +0000656- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
657 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
658 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000665Mac
666---
667
668- PythonLauncher now works correctly when the path to the script contains
669 characters that are treated specially by the shell (such as quotes).
670
671- Bug #1527397: PythonLauncher now launches scripts with the working directory
672 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000673 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000674 expect.

682Core and builtins
683-----------------
684
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000685- Bug #1441486: The literal representation of -(sys.maxint - 1)
686 again evaluates to a int object, not a long.
687
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000688- Bug #1501934: The scope of global variables that are locally assigned
689 using augmented assignment is now correctly determined.
690
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000691- Bug #927248: Recursive method-wrapper objects can now safely
692 be released.
693
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000694- Bug #1417699: Reject locale-specific decimal point in float()
695 and atof().
696
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000697- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
698 omit a default "error" argument for NULL pointer. This allows
699 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000700
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000701- Bug #1519018: 'as' is now validated properly in import statements.
702
Neal Norwitz28746ab2006-07-09 22:14:42 +0000703- On 64 bit systems, int literals that use less than 64 bits are
704 now ints rather than longs.
705
Neal Norwitzed657552006-07-10 00:04:44 +0000706- Bug #1512814, Fix incorrect lineno's when code at module scope
707 started after line 256.
708
Tim Peters32a83612006-07-10 21:08:24 +0000709- New function ``sys._current_frames()`` returns a dict mapping thread
710 id to topmost thread stack frame. This is for expert use, and is
711 especially useful for debugging application deadlocks. The functionality
712 was previously available in Fazal Majid's ``threadframe`` extension
713 module, but it wasn't possible to do this in a wholly threadsafe way from
714 an extension.

731
Thomas Woutersadd19112006-07-05 11:03:49 +0000732- string.Template() now correctly handles tuple-values. Previously,
733 multi-value tuples would raise an exception and single-value tuples would
734 be treated as the value they contain, instead.
735
Martin v. Löwisede77f52006-07-03 13:01:35 +0000736- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

743 degrees and radians.
744
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000745- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000746 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000747

749 is created.
750
Martin v. Löwis7596e832006-07-01 15:33:37 +0000751- Bug #1513223: .close() of a _socketobj now releases the underlying
752 socket again, which then gets closed as it becomes unreferenced.
753
Fred Drake10497c82006-06-29 02:57:48 +0000754- Bug #1504333: Make sgmllib support angle brackets in quoted
755 attribute values.
756
757- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
758 sgmllib ('[' and ']' were not accepted).
759
Georg Brandl1be63af2006-06-28 20:23:25 +0000760- Fix a bug in the turtle module's end_fill function.
761
Brett Cannon53ab5b72006-06-22 16:49:14 +0000762- Bug #1510580: The 'warnings' module improperly required that a Warning
763 category be either a types.ClassType and a subclass of Warning. The proper
764 check is just that it is a subclass with Warning as the documentation states.
765
Georg Brandlad29e632006-06-21 17:45:17 +0000766- The compiler module now correctly compiles the new try-except-finally
767 statement (bug #1509132).
768
Neal Norwitz60373cd2006-06-22 06:30:50 +0000769- The wsgiref package is now installed properly on Unix.
770
Vinay Sajip28e57612006-07-01 10:45:20 +0000771- A bug was fixed in logging.config.fileConfig() which caused a crash on
772 shutdown when fileConfig() was called multiple times.
773
Gerhard Häring762fbd32006-07-02 17:48:30 +0000774- The sqlite3 module did cut off data from the SQLite database at the first
775 null character before sending it to a custom converter. This has been fixed
776 now.
777
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000778Extension Modules
779-----------------
780
Tim Peters112aad32006-07-19 00:03:19 +0000781- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
782 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
783 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000784
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000785- Assigning None to pointer type fields in ctypes structures possible
786 overwrote the wrong fields, this is fixed now.
787
788- Fixed a segfault in _ctypes when ctypes.wintypes were imported
789 on non-Windows platforms.
790
791- Bug #1518190: The ctypes.c_void_p constructor now accepts any
792 integer or long, without range checking.
793
794- Patch #1517790: It is now possible to use custom objects in the ctypes
795 foreign function argtypes sequence as long as they provide a from_param
796 method, no longer is it required that the object is a ctypes type.
797
798- The '_ctypes' extension module now works when Python is configured
799 with the --without-threads option.
800
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000801- Bug #1513646: os.access on Windows now correctly determines write
802 access, again.
803
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000804- Bug #1512695: cPickle.loads could crash if it was interrupted with
805 a KeyboardInterrupt.
806
Neal Norwitza12aa882006-07-06 06:45:08 +0000807- Bug #1296433: parsing XML with a non-default encoding and
808 a CharacterDataHandler could crash the interpreter in pyexpat.

813-----
814
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000815- Automate Windows build process for the Win64 SSL module.
816
Tim Peters32a83612006-07-10 21:08:24 +0000817- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000818 Previously, the slight difference could cause compilation errors of the
819 'zlib' module on systems with more than one version of zlib.
820
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000821- The MSI compileall step was fixed to also support a TARGETDIR
822 with spaces in it.

825 of Tcl/Tk.
826
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000827- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000828 trying to be installed even though it's empty.

852Core and builtins
853-----------------
854
Georg Brandla56b9152006-06-19 06:35:54 +0000855- Patch #1507676: Error messages returned by invalid abstract object operations
856 (such as iterating over an integer) have been improved and now include the
857 type of the offending object to help with debugging.
858
Brett Cannonea3912b2006-06-13 21:46:41 +0000859- Bug #992017: A classic class that defined a __coerce__() method that returned
860 its arguments swapped would infinitely recurse and segfault the interpreter.
861
Neal Norwitz909eb122006-06-12 02:13:21 +0000862- Fix the socket tests so they can be run concurrently.
863
Neal Norwitzb9845e72006-06-12 02:11:18 +0000864- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000865 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000866
Brett Cannon22565aa2006-06-09 22:31:23 +0000867- Bug #532646: object.__call__() will continue looking for the __call__
868 attribute on objects until one without one is found. This leads to recursion
869 when you take a class and set its __call__ attribute to an instance of the
870 class. Originally fixed for classic classes, but this fix is for new-style.
871 Removes the infinite_rec_3 crasher.
872
Georg Brandl24250812006-06-09 18:45:48 +0000873- The string and unicode methods startswith() and endswith() now accept
874 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
875
Brett Cannonde3b0522006-06-08 17:00:45 +0000876- Buffer objects, at the C level, never used the char buffer
877 implementation even when the char buffer for the wrapped object was
878 explicitly requested (originally returned the read or write buffer).
879 Now a TypeError is raised if the char buffer is not present but is
880 requested.
881
Georg Brandlddbaa662006-06-04 21:56:52 +0000882- Patch #1346214: Statements like "if 0: suite" are now again optimized
883 away like they were in Python 2.4.
884
Georg Brandlb7c8f542006-05-27 12:30:25 +0000885- Builtin exceptions are now full-blown new-style classes instead of
886 instances pretending to be classes, which speeds up exception handling
887 by about 80% in comparison to 2.5a2.
888
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000889- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
890 Unicode 4.1.
891
Georg Brandlf4ef1162006-05-26 18:03:31 +0000892- Patch #921466: sys.path_importer_cache is now used to cache valid and
893 invalid file paths for the built-in import machinery which leads to
894 fewer open calls on startup.
895
Tim Peters696cf432006-05-24 21:10:40 +0000896- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
897 of-2 bases. The largest speedup is for inputs with about 1000 decimal
898 digits. Conversion from non-power-of-2 bases remains quadratic-time in
899 the number of input digits (it was and remains linear-time for bases
900 2, 4, 8, 16 and 32).
901
Tim Petersb713ec22006-05-23 18:45:30 +0000902- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
903 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
904 an integer close to ``sys.maxint``. This was repaired by patch
905 #1335972, which also gives a nice speedup.
906
Richard Jonescebbefc2006-05-23 18:28:17 +0000907- Patch #1337051: reduced size of frame objects.
908
909- PyErr_NewException now accepts a tuple of base classes as its
910 "base" parameter.
911
Richard Jones7c88dcc2006-05-23 10:37:38 +0000912- Patch #876206: function call speedup by retaining allocated frame
913 objects.
914
Georg Brandl7b90e162006-05-18 07:01:27 +0000915- Bug #1462152: file() now checks more thoroughly for invalid mode
916 strings and removes a possible "U" before passing the mode to the
917 C library function.
918
Neal Norwitz1004a532006-05-15 07:17:23 +0000919- Patch #1488312, Fix memory alignment problem on SPARC in unicode
920
Neal Norwitz373f0a72006-05-15 07:04:36 +0000921- Bug #1487966: Fix SystemError with conditional expression in assignment
922
Martin v. Löwis879768d2006-05-11 13:28:43 +0000923- WindowsError now has two error code attributes: errno, which carries
924 the error values from errno.h, and winerror, which carries the error
925 values from winerror.h. Previous versions put the winerror.h values
926 (from GetLastError()) into the errno attribute.
927
Martin v. Löwis77736712006-05-04 05:51:03 +0000928- Patch #1475845: Raise IndentationError for unexpected indent.
929
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000930- Patch #1479181: split open() and file() from being aliases for each other.
931
Tim Peters44bd9862006-06-01 13:49:23 +0000932- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
933 methods were always silently ignored by dictionaries when comparing keys.
934 They are now passed through (except when using the C API function
935 ``PyDict_GetItem()``, whose semantics did not change).
936
937- Bug #1456209: In some obscure cases it was possible for a class with a
938 custom ``__eq__()`` method to confuse dict internals when class instances
939 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
940 No, you don't have any code that did this ;-)

946
947- Patch #1462338: Upgrade pyexpat to expat 2.0.0
948
Brett Cannon6ee7d012006-06-08 16:23:04 +0000949- Change binascii.hexlify to accept a read-only buffer instead of only a char
950 buffer and actually follow its documentation.
951
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000952- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
953
Nick Coghlanc649ec52006-05-29 12:43:05 +0000954- Patch #1478788 (modified version): The functional extension module has
955 been renamed to _functools and a functools Python wrapper module added.
956 This provides a home for additional function related utilities that are
957 not specifically about functional programming. See PEP 309.
958
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000959- Patch #1493701: performance enhancements for struct module.
960
Georg Brandl378d5922006-05-17 14:26:50 +0000961- Patch #1490224: time.altzone is now set correctly on Cygwin.
962
Georg Brandl8d3342b2006-05-16 07:38:27 +0000963- Patch #1435422: zlib's compress and decompress objects now have a
964 copy() method.
965
Andrew MacIntyre92913322006-06-13 15:04:24 +0000966- Patch #1454481: thread stack size is now tunable at runtime for thread
967 enabled builds on Windows and systems with Posix threads support.
968
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000969- On Win32, os.listdir now supports arbitrarily-long Unicode path names
970 (up to the system limit of 32K characters).
971
972- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
973 As a result, these functions now raise WindowsError instead of OSError.
974
Tim Peters7a822da2006-05-25 21:50:17 +0000975- ``time.clock()`` on Win64 should use the high-performance Windows
976 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
977 Windows platforms).
978
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000979- Calling Tk_Init twice is refused if the first call failed as that
980 may deadlock.
981
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000982- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
983 accept it without potentially using an uninitialized pointer.
984
985- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
986 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
987 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000988
Gregory P. Smith372b5832006-06-05 18:48:21 +0000989- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000990 [pybsddb project SF patch number 1466734]
991
Gregory P. Smith372b5832006-06-05 18:48:21 +0000992- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
993 parameter is supplied. [SF pybsddb bug #1477863]
994
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000995- bsddb: the __len__ method of a DB object has been fixed to return correct
996 results. It could previously incorrectly return 0 in some cases.
997 Fixes SF bug 1493322 (pybsddb bug 1184012).
998
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000999- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1000 aborts the db transaction safely when a modifier callback fails.
1001 Fixes SF python patch/bug #1408584.
1002
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001003- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001004 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001005 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1006 database calls that would previously deadlock. [SF python bug #775414]
1007
Vinay Sajip28e57612006-07-01 10:45:20 +00001008- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1017 functions.
1018
Martin v. Löwis3798da02006-06-17 18:44:27 +00001019- Patch #812986: Update turtle output even if not tracing.

1027 classes.
1028
Georg Brandl83cc0d02006-06-14 08:50:03 +00001029- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1030 mime.types file for determining MIME types.
1031
Georg Brandl2605ca82006-06-14 06:08:31 +00001032- Bug #1339007: Shelf objects now don't raise an exception in their
1033 __del__ method when initialization failed.
1034
Martin v. Löwisd8251432006-06-14 05:21:04 +00001035- Patch #1455898: The MBCS codec now supports the incremental mode for
1036 double-byte encodings.
1037
Tim Peters43898b42006-06-14 04:09:25 +00001038- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1039 guarantee that adjacent triples in the return list always describe
1040 non-adjacent blocks. Previously, a pair of matching blocks could end
1041 up being described by multiple adjacent triples that formed a partition
1042 of the matching pair.
1043
Greg Ward0e0c9f42006-06-11 16:24:11 +00001044- Bug #1498146: fix optparse to handle Unicode strings in option help,
1045 description, and epilog.
1046
Greg Wardd1c797e2006-06-11 14:42:41 +00001047- Bug #1366250: minor optparse documentation error.
1048
Greg Ward7f547402006-06-11 00:40:49 +00001049- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1050 clarify docs.
1051
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001052- The wsgiref package has been added to the standard library.
1053
Nick Coghlan676725d2006-06-08 13:54:49 +00001054- The functions update_wrapper() and wraps() have been added to the functools
1055 module. These make it easier to copy relevant metadata from the original
1056 function when writing wrapper functions.
1057
Tim Petersd6a9eef2006-06-05 01:48:21 +00001058- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1059 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001060
Martin v. Löwis3f767792006-06-04 19:36:28 +00001061- Patch #1359618: Speed up charmap encoder by using a trie structure
1062 for lookup.
1063
Tim Petersd609b1a2006-06-02 23:22:51 +00001064- The functions in the ``pprint`` module now sort dictionaries by key
1065 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1066 if and only if its display required more than one line, although that
1067 wasn't documented. The new behavior increases predictability; e.g.,
1068 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1069
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001070- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1071 (thanks for J. J. Lee).
1072
Georg Brandl2b330372006-05-28 20:23:12 +00001073- Patch #1496206: improve urllib2 handling of passwords with respect to
1074 default HTTP and HTTPS ports.
1075
George Yoshidaf3c65de2006-05-28 16:39:09 +00001076- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1077
Bob Ippolito7298f272006-05-23 18:43:47 +00001078- Patch #1281707: speed up gzip.readline.
1079
Georg Brandlb89316f2006-05-17 15:51:16 +00001080- Patch #1180296: Two new functions were added to the locale module:
1081 format_string() to get the effect of "format % items" but locale-aware,
1082 and currency() to format a monetary number with currency sign.
1083
Georg Brandle3a25832006-05-17 14:56:04 +00001084- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1085 and several features added, such as speed and geometry control.
1086
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001087- Patch #1488881: add support for external file objects in bz2 compressed
1088 tarfiles.
1089
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001090- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1091 stdout arguments, making it possible to redirect input and output
1092 for remote debugging.
1093
1094- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1095 a couple of issues, notably handling of long file names using the
1096 GNU LONGNAME extension.
1097
1098- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1099 new flag when ``name`` is already the name of an option flag.
1100
1101- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1102 package.
1103
1104- Patch #1472854: make the rlcompleter.Completer class usable on non-
1105 UNIX platforms.

1146-----------------
1147
Thomas Heller1b046642006-04-18 18:51:06 +00001148- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1149 by converting these apis from macros into exported functions again:
1150
1151 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1152 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1153 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1154 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1155 PyRun_String Py_CompileString
1156
Martin v. Löwis45294a92006-04-18 06:24:08 +00001157- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1158
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001159- All uses of PyStructSequence_InitType have been changed to initialize
1160 the type objects only once, even if the interpreter is initialized
1161 multiple times.
1162
Neal Norwitz61546162006-04-14 05:20:28 +00001163- Bug #1454485, array.array('u') could crash the interpreter. This was
1164 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1165 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1166
1167- Py_UNICODE is unsigned. It was always documented as unsigned, but
1168 due to a bug had a signed value in previous versions.
1169
Tim Peters3a5e8b12006-04-11 01:44:07 +00001170- Patch #837242: ``id()`` of any Python object always gives a positive
1171 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1172 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001173 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001174 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001175
Tim Peters3a5e8b12006-04-11 01:44:07 +00001176 def __hash__(self):
1177 return id(self) # WRONG
1178
1179 because a hash result must be a (short) Python int but it was always
1180 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001181 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001182 was always usable as a hash value before this patch. That's no longer
1183 necessarily so.
1184
1185- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001186 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001187 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001188 #1454844)
1189
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001190- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1191 involving generators that have paused outside of any ``try`` or ``with``
1192 blocks. (In 2.5a1, a paused generator that was part of a reference
1193 cycle could not be garbage collected, regardless of whether it was
1194 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001226- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1227 a doctest to be skipped (the code is not run, and the expected output
1228 or exception is ignored).
1229
Nick Coghlanda2268f2006-04-24 04:37:15 +00001230- Fixed contextlib.nested to cope with exceptions being raised and
1231 caught inside exit handlers.
1232
Greg Wardab05edc2006-04-23 03:47:58 +00001233- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1234 hex, octal, or binary; add ``append_const`` action; keep going if
1235 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1236 added ``epilog`` for better help generation).
1237
Tim Peters21fbd572006-04-21 21:18:10 +00001238- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1239 called from a thread spawned as a side effect of importing a module.
1240
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001241- The pydoc module now supports documenting packages contained in
1242 .zip or .egg files.
1243
1244- The pkgutil module now has several new utility functions, such
1245 as ``walk_packages()`` to support working with packages that are either
1246 in the filesystem or zip files.
1247
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001248- The mailbox module can now modify and delete messages from
1249 mailboxes, in addition to simply reading them. Thanks to Gregory
1250 K. Johnson for writing the code, and to the 2005 Google Summer of
1251 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001252
Tim Petersc7605f22006-04-17 21:12:33 +00001253- The ``__del__`` method of class ``local`` in module ``_threading_local``
1254 returned before accomplishing any of its intended cleanup.

1261
Anthony Baxtere29002c2006-04-12 12:07:31 +00001262- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1263 Windows. Bug #1469163.
1264
Phillip J. Eby47032112006-04-11 01:07:43 +00001265- The warnings, linecache, inspect, traceback, site, and doctest modules
1266 were updated to work correctly with modules imported from zipfiles or
1267 via other PEP 302 __loader__ objects.
1268
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001269- Patch #1467770: Reduce usage of subprocess._active to processes which
1270 the application hasn't waited on.
1271

1275
Skip Montanaro262fb922006-04-21 02:31:07 +00001276- The pstats.Stats class accepts an optional stream keyword argument to
1277 direct output to an alternate file-like object.
1278
Anthony Baxter51bcb682006-04-05 14:51:42 +00001279Build
1280-----
1281
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001282- The Makefile now has a reindent target, which runs reindent.py on
1283 the library.
1284
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001285- Patch #1470875: Building Python with MS Free Compiler
1286
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001287- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001288
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001289- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1290 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001291 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001292 CXX from --with-cxx-main, see description in README.
1293
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001294- Patch #1429775: Link extension modules with the shared libpython.
1295
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001296- Fixed a libffi build problem on MIPS systems.
1297
Tim Peters8931ff12006-05-13 23:28:20 +00001298- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1299 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1300 and "%zu" for unsigned integers of type ``size_t``.
1301
Anthony Baxter51bcb682006-04-05 14:51:42 +00001302Tests
1303-----
1304
Nick Coghlanda2268f2006-04-24 04:37:15 +00001305- test_contextlib now checks contextlib.nested can cope with exceptions
1306 being raised and caught inside exit handlers.
1307
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001308- test_cmd_line now checks operation of the -m and -c command switches
1309
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001310- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1311 it separately and by hand. It also wasn't cleaning up its changes to
1312 the current Decimal context.
1313
Thomas Woutersabd08882006-04-26 15:53:30 +00001314- regrtest.py now has a -M option to run tests that test the new limits of
1315 containers, on 64-bit architectures. Running these tests is only sensible
1316 on 64-bit machines with more than two gigabytes of memory. The argument
1317 passed is the maximum amount of memory for the tests to use.
1318
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001319Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001325Documentation
1326-------------
1327
Tim Petersb06d28c2006-05-12 01:57:59 +00001328- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1329
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001330- PEP 343: Added Context Types section to the library reference
1331 and attempted to bring other PEP 343 related documentation into
1332 line with the implementation and/or python-dev discussions.
1333
Tim Peters8dc73d22006-04-24 02:03:16 +00001334- Bug #1337990: clarified that ``doctest`` does not support examples
1335 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001336

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001338What's New in Python 2.5 alpha 1?
1339=================================
1340
Anthony Baxterebed3f62006-04-03 15:03:44 +00001341*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001342
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001343Core and builtins
1344-----------------
1345
Nick Coghlan43832302006-04-23 17:04:07 +00001346- PEP 338: -m command line switch now delegates to runpy.run_module
1347 allowing it to support modules in packages and zipfiles
1348
Martin v. Löwisc661b882006-04-20 04:54:23 +00001349- On Windows, .DLL is not an accepted file name extension for
1350 extension modules anymore; extensions are only found if they
1351 end in .PYD.
1352
Martin v. Löwisea62d252006-04-03 10:56:49 +00001353- Bug #1421664: sys.stderr.encoding is now set to the same value as
1354 sys.stdout.encoding.
1355
Neal Norwitz92e212f2006-04-03 04:48:37 +00001356- __import__ accepts keyword arguments.
1357
Georg Brandlccadf842006-03-31 18:54:53 +00001358- Patch #1460496: round() now accepts keyword arguments.
1359
Anthony Baxter262c00a2006-03-30 10:53:17 +00001360- Fixed bug #1459029 - unicode reprs were double-escaped.
1361
Hye-Shik Changd478f342006-03-23 12:32:36 +00001362- Patch #1396919: The system scope threads are reenabled on FreeBSD
1363 5.4 and later versions.
1364
Neal Norwitze98ccf62006-03-23 05:39:47 +00001365- Bug #1115379: Compiling a Unicode string with an encoding declaration
1366 now gives a SyntaxError.
1367
Georg Brandlabd1ff82006-03-18 07:59:59 +00001368- Previously, Python code had no easy way to access the contents of a
1369 cell object. Now, a ``cell_contents`` attribute has been added
1370 (closes patch #1170323).
1371
Tim Peterscf79aac2006-03-16 01:14:46 +00001372- Patch #1123430: Python's small-object allocator now returns an arena to
1373 the system ``free()`` when all memory within an arena becomes unused
1374 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1375 freed. Some applications will see a drop in virtual memory size now,
1376 especially long-running applications that, from time to time, temporarily
1377 use a large number of small objects. Note that when Python returns an
1378 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001379 platform C library will in turn return that memory to the operating system.
1380 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001381 appears to be effective at least on Microsoft C and gcc-based systems.
1382 Thanks to Evan Jones for hard work and patience.
1383
Georg Brandl533ff6f2006-03-08 18:09:27 +00001384- Patch #1434038: property() now uses the getter's docstring if there is
1385 no "doc" argument given. This makes it possible to legitimately use
1386 property() as a decorator to produce a read-only property.
1387
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001388- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1389 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1390 of requiring an int or long in slicing and a few other contexts, enabling
1391 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1392
Neal Norwitz995acdf2006-03-07 05:01:00 +00001393- Fixed various bugs reported by Coverity's Prevent tool.
1394
Brett Cannonbf364092006-03-01 04:25:17 +00001395- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1396 new exception base class, BaseException, which has a new message attribute.
1397 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1398 Raising a string exception now raises a DeprecationWarning.
1399
Thomas Woutersfb609f42006-02-28 16:37:25 +00001400- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1401 explicitly relative, using 'from .module import name' to mean 'from the same
1402 package as this module is in. Imports without dots still default to the
1403 old relative-then-absolute, unless 'from __future__ import
1404 absolute_import' is used.
1405
Brett Cannona7446e32006-02-27 23:39:10 +00001406- Properly check if 'warnings' raises an exception (usually when a filter set
1407 to "error" is triggered) when raising a warning for raising string
1408 exceptions.
1409
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001410- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001411 The name was removed from Include/code.h.
1412
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001413- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001414
Guido van Rossum1968ad32006-02-25 22:38:04 +00001415- Patch 1433928:
1416 - The copy module now "copies" function objects (as atomic objects).
1417 - dict.__getitem__ now looks for a __missing__ hook before raising
1418 KeyError.
1419
Tim Peters84ef21c2006-02-28 20:39:06 +00001420- PEP 343: with statement implemented. Needs ``from __future__ import
1421 with_statement``. Use of 'with' as a variable will generate a warning.
1422 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001423 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001424 The following objects have __context__ methods:
1425 - The built-in file type.
1426 - The thread.LockType type.
1427 - The following types defined by the threading module:
1428 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1429 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001430
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001431- Fix the encodings package codec search function to only search
1432 inside its own package. Fixes problem reported in patch #1433198.
1433
1434 Note: Codec packages should implement and register their own
1435 codec search function. PEP 100 has the details.
1436
Tim Peters9ea89d22006-06-04 03:26:02 +00001437- PEP 353: Using ``Py_ssize_t`` as the index type.
1438
1439- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1440 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1441 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1442 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1443 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001444
Neal Norwitzfc76d632006-01-10 06:03:13 +00001445- Patch #1400181, fix unicode string formatting to not use the locale.
1446 This is how string objects work. u'%f' could use , instead of .
1447 for the decimal point. Now both strings and unicode always use periods.
1448
Neal Norwitz671b9e32006-01-09 07:07:12 +00001449- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1450 configure would break checking curses.h.
1451
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001452- Bug #959576: The pwd module is now builtin. This allows Python to be
1453 built on UNIX platforms without $HOME set.
1454
Neal Norwitzc10978f2005-12-19 06:07:16 +00001455- Bug #1072182, fix some potential problems if characters are signed.
1456
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001457- Bug #889500, fix line number on SyntaxWarning for global declarations.
1458
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001459- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1460
Neal Norwitze7214a12005-12-18 05:03:17 +00001461- Support for converting hex strings to floats no longer works.
1462 This was not portable. float('0x3') now raises a ValueError.
1463
Barry Warsaw2a38a862005-12-18 01:27:35 +00001464- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001465 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001466 is now displayed in interactive prompt banner.
1467
Georg Brandlfa166682005-12-17 21:45:17 +00001468- Implementation of PEP 341 - Unification of try/except and try/finally.
1469 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001470 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001471
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001472- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1473 now encodes backslash correctly.
1474
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001475- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001477- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001478 and long longs.
1479
Neal Norwitz67715f02005-11-09 06:59:35 +00001480- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001481 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001482 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001483
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001484- Replaced most Unicode charmap codecs with new ones using the
1485 new Unicode translate string feature in the builtin charmap
1486 codec; the codecs were created from the mapping tables available
1487 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1488 encodings now include a mapping for the Apple logo)
1489
Tim Peterse3547fd2005-12-16 23:13:57 +00001490- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001491
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001492- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001493
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001494- A new AST parser implementation was completed. The abstract
1495 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001496 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001497
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001498- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001499 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1500
Neal Norwitz708e51a2005-10-03 04:48:15 +00001501- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1502
Neal Norwitz11bd1192005-10-03 00:54:56 +00001503- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1504 Provide a warning when a directory is passed on the command line.
1505
Neal Norwitz40d37812005-10-02 01:48:49 +00001506- Fix segfault with invalid coding.
1507
1508- SF bug #772896: unknown encoding results in MemoryError.
1509
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001510- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001511 supported a __len__() method which evaluated to False when the iterator
1512 was empty.
1513
Guido van Rossum630db602005-09-20 18:49:54 +00001514- On 64-bit platforms, when __len__() returns a value that cannot be
1515 represented as a C int, raise OverflowError.
1516
Skip Montanarof8948ca2005-09-19 03:54:46 +00001517- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001518 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001519
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001520- SF bug #893549: parsing keyword arguments was broken with a few format
1521 codes.
1522
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001523- Changes donated by Elemental Security to make it work on AIX 5.3
1524 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1525 bug #105470: test_pwd fails on 64bit system (Opteron).
1526
Guido van Rossum539c6622005-09-14 17:49:54 +00001527- Changes donated by Elemental Security to make it work on HP-UX 11 on
1528 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1529
Georg Brandl4550b8d2005-08-26 06:43:52 +00001530- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001531 (fixes bug #1119418).
1532
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001533- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1534
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001535- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1536 exceptions that cause a function to exit.
1537
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001538- The implementation of set() and frozenset() was revised to use its
1539 own internal data structure. Memory consumption is reduced by 1/3
1540 and there are modest speed-ups as well. The API is unchanged.
1541
Tim Petersde7990b2005-07-17 23:45:23 +00001542- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1543
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001544- SF bug #1229429: PyObject_CallMethod failed to decrement some
1545 reference counts in some error exit cases.
1546
Tim Petersecc6e6a2005-07-10 22:30:55 +00001547- SF bug #1185883: Python's small-object memory allocator took over
1548 a block managed by the platform C library whenever a realloc specified
1549 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001550 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001551 portable way to copy data from the C-managed block into Python's
1552 small-object space without risking a memory fault. Python's small-object
1553 realloc now leaves such blocks under the control of the platform C
1554 realloc.
1555
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001556- SF bug #1232517: An overflow error was not detected properly when
1557 attempting to convert a large float to an int in os.utime().
1558
Raymond Hettinger3296e692005-06-29 23:29:56 +00001559- SF bug #1224347: hex longs now print with lowercase letters just
1560 like their int counterparts.
1561
Michael W. Hudson188d4362005-06-20 16:52:57 +00001562- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1563 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1564 interpreter states; back out that fix and do a better job (see
1565 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1566 for a longer write-up of the problem).
1567
Michael W. Hudsondf888462005-06-03 14:41:55 +00001568- SF patch #1180995: marshal now uses a binary format by default when
1569 serializing floats.
1570
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001571- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1572 the routines that promise to produce IEEE 754 binary representations
1573 of floats now simply copy bytes around.
1574
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001575- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1576 278.
1577
Brett Cannonc3647ac2005-04-26 03:45:26 +00001578- patch #1109424: int, long, float, complex, and unicode now check for the
1579 proper magic slot for type conversions when subclassed. Previously the
1580 magic slot was ignored during conversion. Semantics now match the way
1581 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001582 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001583 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001584 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001585
Barry Warsawc8d907c2005-04-19 23:43:40 +00001586- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1587 NULL, now raise an AttributeError when attempting to set or delete the
1588 attribute. Previously a TypeError was raised, but this was inconsistent
1589 with the equivalent pure-Python implementation.
1590
Michael W. Hudson774479c2005-04-18 08:46:17 +00001591- It is now safe to call PyGILState_Release() before
1592 PyEval_InitThreads() (note that if there is reason to believe there
1593 are multiple threads around you still must call PyEval_InitThreads()
1594 before using the Python API; this fix is for extension modules that
1595 have no way of knowing if Python is multi-threaded yet).
1596
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001597- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1598 disabled caused a crash.
1599
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001600- Bug #1165306: instancemethod_new allowed the creation of a method
1601 with im_class == im_self == NULL, which caused a crash when called.
1602
Tim Petersecc6e6a2005-07-10 22:30:55 +00001603- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001604 fixes the crash seen in bug #1165761
1605
Raymond Hettinger96229b12005-03-11 06:49:40 +00001606- Added two new builtins, any() and all().
1607
Brett Cannon409d8f22005-03-05 06:47:57 +00001608- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001609 (e.g., ``class C(): pass`` is no longer a syntax error).
1610 Patch #1176012 added support to the 'parser' module and 'compiler' package
1611 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001612
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001613- Patch #1115086: Support PY_LONGLONG in structmember.
1614
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001615- Bug #1155938: new style classes did not check that __init__() was
1616 returning None.
1617
Tim Petersecc6e6a2005-07-10 22:30:55 +00001618- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001619 ('\') with a specific error message.
1620
Martin v. Löwisff232d72005-03-03 09:24:38 +00001621- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1622
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001623- Bug #1124295: the __name__ attribute of file objects was
1624 inadvertently made inaccessible in restricted mode.
1625
Tim Petersecc6e6a2005-07-10 22:30:55 +00001626- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001627 an ferror() call.
1628
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001629- min() and max() now support key= arguments with the same meaning as in
1630 list.sort().
1631
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001632- The peephole optimizer now performs simple constant folding in expressions:
1633 (2+3) --> (5).
1634
Raymond Hettingera422c342005-01-11 03:03:27 +00001635- set and frozenset objects can now be marshalled. SF #1098985.
1636
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001637- Bug #1077106: Poor argument checking could cause memory corruption
1638 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001639
Jeremy Hyltonab630502005-02-04 18:44:06 +00001640- The parser did not complain about future statements in illegal
1641 positions. It once again reports a syntax error if a future
1642 statement occurs after anything other than a doc string.
1643
Neil Schemenauercf52c072005-08-12 17:34:58 +00001644- Change the %s format specifier for str objects so that it returns a
1645 unicode instance if the argument is not an instance of basestring and
1646 calling __str__ on the argument returns a unicode instance.
1647
Tim Petersf4e69282006-02-27 17:15:31 +00001648- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1649 current thread state when the auto-GIL-state machinery knows about
1650 it (since the thread state is being deleted, continuing to remember it
1651 can't help, but can hurt if another thread happens to get created with
1652 the same thread id).
1653
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001654Extension Modules
1655-----------------
1656

Neal Norwitz10be10c2006-03-16 06:50:13 +00001670 util, whatsound, whrandom, zmod
1671
1672- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1673
1674- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001675 is deprecated. The undocumented re.engine variable no longer exists.
1676
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001677- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1678 SS2 (single-shift 2) escape sequences correctly.
1679
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001680- The unicodedata module was updated to the 4.1 version of the Unicode
1681 database. The 3.2 version is still available as unicodedata.db_3_2_0
1682 for applications that require this specific version (such as IDNA).
1683
Neal Norwitzb62c4332006-03-04 18:35:47 +00001684- The timing module is no longer built by default. It was deprecated
1685 in PEP 4 in Python 2.0 or earlier.
1686
Guido van Rossum1968ad32006-02-25 22:38:04 +00001687- Patch 1433928: Added a new type, defaultdict, to the collections module.
1688 This uses the new __missing__ hook behavior added to dict (see above).
1689
Georg Brandldbd83392006-02-20 09:42:33 +00001690- Bug #854823: socketmodule now builds on Sun platforms even when
1691 INET_ADDRSTRLEN is not defined.
1692
Georg Brandlf4f44152006-02-18 22:29:33 +00001693- Patch #1393157: os.startfile() now has an optional argument to specify
1694 a "command verb" to invoke on the file.
1695
Neal Norwitz082b2df2006-02-07 07:04:46 +00001696- Bug #876637, prevent stack corruption when socket descriptor
1697 is larger than FD_SETSIZE.
1698
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001699- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1700 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1701 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1704 than the system default domain.
1705
Martin v. Löwis14694662006-02-03 12:54:16 +00001706- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1707 are reported, the limit on path name lengths is removed, and stat reports
1708 WindowsError now (instead of OSError).
1709
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001710- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001784- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1785 the request code argument, which results in more C-like behaviour
1786 for large or negative values.
1787
Tim Petersecc6e6a2005-07-10 22:30:55 +00001788- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1797 available on the platform.
1798
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001799- Bug #1166660: The readline module could segfault if hook functions
1800 were set in a different thread than that which called readline.
1801
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00001802- collections.deque objects now support a remove() method.
1803
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001804- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001828- the cPickle module no longer accepts the deprecated None option in the
1829 args tuple returned by __reduce__().
1830
Raymond Hettingerb2594052004-12-05 09:25:51 +00001831- itertools.islice() now accepts None for the start and step arguments.

1833 islice(s.start, s.stop, s.step)
1834
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001835- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001844- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1845 been renamed to have only a single underscore prefix. This was done to
1846 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001847
Nick Coghlan43832302006-04-23 17:04:07 +00001848- PEP 338: new module runpy defines a run_module function to support
1849 executing modules which provide access to source code or a code object
1850 via the PEP 302 import mechanisms.
1851
Anthony Baxter93f5b932006-04-03 08:05:07 +00001852- The email module's parsedate_tz function now sets the daylight savings
1853 flag to -1 (unknown) since it can't tell from the date whether it should

1860 in attribute values.
1861
Anthony Baxterc51ee692006-04-01 00:57:31 +00001862- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001863 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001864 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001865 module will not be built.
1866
Tim Petersc17976e2006-04-01 00:26:53 +00001867- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1868 aren't officially supported here, and trying to use them will probably
1869 raise an exception some day. But dicts have been allowed, and "mostly
1870 worked", so support for them won't go away without warning.
1871
Georg Brandl338ef7d2006-03-31 18:42:16 +00001872- Bug #1445068: getpass.getpass() can now be given an explicit stream
1873 argument to specify where to write the prompt.
1874
Georg Brandl22ec80b2006-03-31 18:25:44 +00001875- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1884 to make it easier to monitor when daemon threads have completed
1885 processing all enqueued tasks. Patch #1455676.
1886

1890
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001891- email 4.0 package now integrated. This is largely the same as the email 3.0
1892 package that was included in Python 2.3, except that PEP 8 module names are
1893 now used (e.g. mail.message instead of email.Message). The MIME classes
1894 have been moved to a subpackage (e.g. email.mime.text instead of
1895 email.MIMEText). The old names are still supported for now. Several
1896 deprecated Message methods have been removed and lots of bugs have been
1897 fixed. More details can be found in the email package documentation.
1898
Walter Dörwald40108c92006-03-27 08:15:44 +00001899- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1900 (a subclass of tuple) that provides incremental decoders and encoders
1901 (a way to use stateful codecs without the stream API). Python functions
1902 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1903 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1904 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001905
Walter Dörwald067db482006-03-15 22:17:27 +00001906- Patch #1359365: Calling next() on a closed StringIO.String object raises
1907 a ValueError instead of a StopIteration now (like file and cString.String do).
1908 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1909 called before (like file and StringIO.StringIO do).

Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001922- PEP 343: new module contextlib.py defines decorator @contextmanager
1923 and helpful context managers nested() and closing().
1924

Martin v. Löwis3e865952006-01-24 15:51:21 +00001959 specifications, raises IOErrors when proxies for unsupported protocols
1960 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001983 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1984 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1985 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1986 Ronald L. Rivest offered this advice for Python:
1987
1988 "The consensus of researchers in this area (at least as
1989 expressed at the NIST Hash Function Workshop 10/31/05),
1990 is that SHA-256 is a good choice for the time being, but
1991 that research should continue, and other alternatives may
1992 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001993
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001994- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00002039
Georg Brandlb9256022005-08-24 18:46:39 +00002040- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2041 ContentTooShortException, when the actually downloaded size does not
2042 match the Content-Length header.
2043
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002044- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2045
Martin v. Löwis56066d22005-08-24 07:38:12 +00002046- Bug #1178484: Return complete lines from codec stream readers
2047 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002048 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002049
Georg Brandl6d2b3462005-08-24 07:36:17 +00002050- Bug #1192315: Disallow negative arguments to clear() in pdb.

2063
Georg Brandla4a8b822005-07-15 09:13:21 +00002064- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2065 parameter, but uses the usual "kwargs=None".
2066
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002067- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002068 Patch #1209527 (Contributed by Connelly).
2069
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002070- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2071 to W3C name (404 -> 'Not Found'). RFE #1216944.
2072
Georg Brandl9e43acf2005-07-04 17:16:07 +00002073- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2074 as this can cause problems with apps closing all file descriptors.
2075
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002076- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002077 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002078
Georg Brandl2f210b62005-06-26 22:09:06 +00002079- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2080
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002081- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002086- The tokenize module now detects and reports indentation errors.
2087 Bug #1224621.
2088
Raymond Hettinger68c04532005-06-10 11:05:19 +00002089- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002090 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002091 the generate_tokens() function now accepts a callable argument that
2092 terminates by raising StopIteration.
2093
Georg Brandl9166e1a2005-06-04 09:20:03 +00002094- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2095
Georg Brandl268e61c2005-06-03 14:28:50 +00002096- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2097 component of the path.
2098
Skip Montanaro174dd222005-05-14 20:54:16 +00002099- Patch #1120353: The xmlrpclib module provides better, more transparent,
2100 support for datetime.{datetime,date,time} objects. With use_datetime set
2101 to True, applications shouldn't have to fiddle with the DateTime wrapper
2102 class at all.
2103
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002104- distutils.commands.upload was added to support uploading distribution
2105 files to PyPI.
2106
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002107- distutils.commands.register now encodes the data as UTF-8 before posting
2108 them to PyPI.
2109
Raymond Hettinger267b8682005-03-27 10:47:39 +00002110- decimal operator and comparison methods now return NotImplemented
2111 instead of raising a TypeError when interacting with other types. This
2112 allows other classes to implement __radd__ style methods and have them
2113 work as expected.
2114
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002115- Bug #1163325: Decimal infinities failed to hash. Attempting to
2116 hash a NaN raised an InvalidOperation instead of a TypeError.
2117
Tim Petersecc6e6a2005-07-10 22:30:55 +00002118- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002119 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2120

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002130 profile.py if available.
2131
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002132- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.

2138
Martin v. Löwise869eb12005-03-03 09:46:07 +00002139- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2140

2152
Guido van Rossumd0641422005-02-03 15:01:24 +00002153- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2154 disables recursive traversal through instance attributes, which can
2155 be exploited in various ways.
2156
Tim Peterse3547fd2005-12-16 23:13:57 +00002157- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002158 flags on the HTTP listening socket.
2159
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002160- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2161 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2162
Fred Drakefbdeaad2006-07-29 16:56:15 +00002163- Patches #893642, #1039083: add allow_none, encoding arguments to
2164 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002165
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002166- Bug #1110478: Revert os.environ.update to do putenv again.
2167
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002168- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2169
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002170- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2171
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002172- Enhancements to the csv module:
2173
2174 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002175 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002176 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002177 + Dialect parameter parsing has been re-implemented to improve error
2178 reporting.
2179 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2180 dictates.
2181 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002182 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002183 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002184 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2185 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002186 + reader now allows \r characters to be quoted (previously it only allowed
2187 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002188 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002189 + Dialect classes passed to the module are no longer instantiated by
2190 the module before being parsed (the former validation scheme required
2191 this, but the mechanism was unreliable).
2192 + The dialect registry now contains instances of the internal
2193 C-coded dialect type, rather than references to python objects.
2194 + the internal c-coded dialect type is now immutable.
2195 + register_dialect now accepts the same keyword dialect specifications
2196 as the reader and writer, allowing the user to register dialects
2197 without first creating a dialect class.
2198 + a configurable limit to the size of parsed fields has been added -
2199 previously, an unmatched quote character could result in the entire
2200 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002201 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002202 the parser field size limit (returning the former limit). The initial
2203 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002204 + A line_num attribute has been added to the reader object, which tracks
2205 the number of lines read from the source iterator. This is not
2206 the same as the number of records returned, as records can span
2207 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002208 + reader and writer objects were not being registered with the cyclic-GC.
2209 This has been fixed.
2210
Brett Cannone6539c42005-01-08 02:43:53 +00002211- _DummyThread objects in the threading module now delete self.__block that is
2212 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2213 lock primitives tend to be limited in number and thus should not be wasted on
2214 a _DummyThread object. Fixes bug #1089632.
2215
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002216- The imghdr module now detects Exif files.
2217
Raymond Hettinger6065d322004-12-20 23:51:53 +00002218- StringIO.truncate() now correctly adjusts the size attribute.
2219 (Bug #951915).
2220
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002221- locale.py now uses an updated locale alias table (built using
2222 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2223 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002224 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002225
Raymond Hettinger3557f422004-12-07 12:02:02 +00002226- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2227
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002228- the pickle module no longer accepts the deprecated None option in the
2229 args tuple returned by __reduce__().
2230
Brett Cannon84667c02004-12-07 03:25:18 +00002231- optparse now optionally imports gettext. This allows its use in setup.py.
2232
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002233- the pickle module no longer uses the deprecated bin parameter.
2234
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002235- the shelve module no longer uses the deprecated binary parameter.
2236
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002237- the pstats module no longer uses the deprecated ignore() method.
2238
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002239- the filecmp module no longer uses the deprecated use_statcache argument.
2240
Raymond Hettinger664347b2004-12-04 21:21:53 +00002241- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2242 extended or overridden by subclasses. Formerly, the subclassed method would
2243 be ignored by the rest of the module. (Bug #1078905).
2244
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002245- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002246 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002247
Walter Dörwald36733692004-12-22 12:50:50 +00002248- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2249 once when a size argument is given. This prevents a buffer overflow in the
2250 tokenizer with very long source lines.
2251
Barry Warsaw538561e2006-01-01 21:48:54 +00002252- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2253 immediately after creating the object, without any intervening
2254 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002255
Skip Montanaro05885812005-01-16 20:48:27 +00002256- The reconvert.quote function can now emit triple-quoted strings. The
2257 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002258
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002259- ``UserString.MutableString`` now supports negative indices in
2260 ``__setitem__`` and ``__delitem__``
2261
Greg Ward40407942005-03-05 02:53:17 +00002262- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2263 correctly.
2264
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002265- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2266 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2267 character even if the user has passed a size parameter to get a proper
2268 line ending. Remove the special handling of a "\r\n" that has been split
2269 between two lines.
2270
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002271- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2272 about illegal code points. The codec now supports PEP 293 style error
2273 handlers.
2274
Walter Dörwald78a78b02005-09-01 12:04:29 +00002275- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002276 from the input stream, so that the output is a byte string in the correct
2277 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002278
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002279- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2280 considering it exactly like a '*'.
2281
Walter Dörwald007f8df2005-10-09 19:42:27 +00002282- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2283 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002284
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002285- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2286
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002287- Patch #1413711: Certain patterns of differences were making difflib
2288 touch the recursion limit.
2289
Walter Dörwald58917a62006-03-31 15:26:22 +00002290- Bug #947906: An object oriented interface has been added to the calendar
2291 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002292 called as a script (e.g. via ``python -mcalendar``). Localized month and
2293 weekday names can be ouput (even if an exotic encoding is used) using
2294 special classes that use unicode.

2298
Neal Norwitz602d3392006-03-31 08:21:40 +00002299- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2300 by using -mieee gcc option.
2301

2303
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002304- Build support for Win64-AMD64 was added.
2305
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002306- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2307
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002308- Patch #881820: look for openpty and forkpty also in libbsd.
2309
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002310- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2311 The zlib module is now builtin on Windows.
2312
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002313- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2314
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002315- Bug #1189330: configure did not correctly determine the necessary
2316 value of LINKCC if python was built with GCC 4.0.
2317
Trent Mick8321b422005-07-26 02:29:21 +00002318- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2319 vulnerability in zlib 1.2.1 and 1.2.2.
2320
Brett Cannon08cd5982005-04-24 22:26:38 +00002321- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2322 flags that change binary compatibility. Changes were also made to
2323 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002324 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002325
Bob Ippolitoed233462005-03-29 13:47:59 +00002326- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2327 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2328 no longer exists). This configure patch makes things right.
2329
Martin v. Löwise2713be2005-03-08 15:03:08 +00002330- Bug #1158607: Build with --disable-unicode again.
2331
Brett Cannon46d96232005-02-16 00:07:19 +00002332- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2333 defined. Discovered as a result of not being able to build on OS X.
2334
Brett Cannon516592f2004-12-07 00:42:59 +00002335- setup.py now uses the directories specified in LDFLAGS using the -L option
2336 and in CPPFLAGS using the -I option for adding library and include
2337 directories, respectively, for compiling extension modules against. This has
2338 led to the core being compiled using the values in CPPFLAGS. It also removes
2339 the need for the special-casing of both DarwinPorts and Fink for darwin since
2340 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2341 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2342 Fink, ``-I/opt/local/include`` for DarwinPorts).
2343
Brett Cannon43802422005-02-10 20:48:03 +00002344- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2345 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2346 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2347 Closes bug #1096244. Thanks Gregory Bond.

2350-----
2351
Tim Petersc9d78aa2006-03-26 23:27:58 +00002352- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2353 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2354 is obtained via the ``PyObject_`` family, it must be released via the
2355 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2356 always been officially true, but when Python's small-object allocator was
2357 introduced, an attempt was made to cater to a few extension modules
2358 discovered at the time that obtained memory via ``PyObject_New`` but
2359 released it via ``PyMem_DEL``. It's years later, and if such code still
2360 exists it will fail now (probably with segfaults, but calling wrong
2361 low-level memory management functions can yield many symptoms).
2362
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002363- Added a C API for set and frozenset objects.
2364

2366
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002367- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2368 mapping argument now. This string is used as a mapping table. Byte values
2369 greater than the length of the string and 0xFFFE are treated as undefined
2370 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002377
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002378- Patch #1276356: New resource "urlfetch" is implemented. This enables
2379 even impatient people to run tests that require remote files.
