Guido van Rossumc69ac252006-08-10 18:09:25 +0000343What's New in Python 2.5 release candidate 1?
344=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000345
Anthony Baxterb4096662006-08-16 03:42:26 +0000346*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000347
348Core and builtins
349-----------------
350
Neal Norwitz24b6f202006-09-05 04:43:56 +0000351- Fix infinite recursion when subclassing long and overriding __hash__.
352
353- Fix concatenation (+=) of long strings.
354
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000355- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000356 compared equal or unequal to a string and a UnicodeDecodeError
357 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000358
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000359 Instead, the equal (==) and unequal (!=) comparison operators will
360 now issue a UnicodeWarning and interpret the two objects as
361 unequal. The UnicodeWarning can be filtered as desired using
362 the warning framework, e.g. silenced completely, turned into an
363 exception, logged, etc.
364
365 Note that compare operators other than equal and unequal will still
366 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000367
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000368- Fix segfault when doing string formatting on subclasses of long.
369
370- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
371 with new-style classes.
372
373- Fix bug related to __len__ functions returning negative values with
374 classic classes.
375
376- Patch #1538606, Fix __index__() clipping. There were some problems
377 discovered with the API and how integers that didn't fit into Py_ssize_t
378 were handled. This patch attempts to provide enough alternatives
379 to effectively use __index__.
380
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000381- Bug #1536021: __hash__ may now return long int; the final hash
382 value is obtained by invoking hash on the long int.
383
Thomas Hellerab1049c2006-08-08 17:37:00 +0000384- Bug #1536786: buffer comparison could emit a RuntimeWarning.
385
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000386- Bug #1535165: fixed a segfault in input() and raw_input() when
387 sys.stdin is closed.
388
Thomas Heller74d36f02006-08-04 18:17:40 +0000389- On Windows, the PyErr_Warn function is now exported from
390 the Python dll again.
391
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000392- Bug #1191458: tracing over for loops now produces a line event
393 on each iteration. Fixing this problem required changing the .pyc
394 magic number. This means that .pyc files generated before 2.5c1
395 will be regenerated.
396
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000397- Bug #1333982: string/number constants were inappropriately stored
398 in the byte code and co_consts even if they were not used, ie
399 immediately popped off the stack.
400
Georg Brandle9462c72006-08-04 18:03:37 +0000401- Fixed a reference-counting problem in property().
402
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000403
404Library
405-------
406
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000407- Fix a bug in the ``compiler`` package that caused invalid code to be
408 generated for generator expressions.
409
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000410- The distutils version has been changed to 2.5.0. The change to
411 keep it programmatically in sync with the Python version running
412 the code (introduced in 2.5b3) has been reverted. It will continue
413 to be maintained manually as static string literal.
414
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000415- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000416 and this cannot be converted to the required C type, an exception is
417 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000418 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000419
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000420- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000421 an exception.
422
Tim Peterscbdd3502006-09-05 01:47:53 +0000423- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000424 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000425 workarounds for clocks with low resolution, to stop the code yielding
426 duplicate UUIDs.
427
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000428- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
429 before raising SystemExit, allowing IDLE to honor quit() and exit().
430
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000431- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
432
Georg Brandl7a1af772006-08-14 21:55:28 +0000433- Patch #1536071: trace.py should now find the full module name of a
434 file correctly even on Windows.
435
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000436- logging's atexit hook now runs even if the rest of the module has
437 already been cleaned up.
438
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000439- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000440
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000441- Bug #1531405, format_exception no longer raises an exception if
442 str(exception) raised an exception.
443
Neil Schemenauer06ded092006-08-04 16:20:30 +0000444- Fix a bug in the ``compiler`` package that caused invalid code to be
445 generated for nested functions.
446
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000447
448Extension Modules

452
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000453- Patch #1511317: don't crash on invalid hostname (alias) info.
454
Georg Brandl3335a7a2006-08-14 21:42:55 +0000455- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
456 raises the correct exceptions.
457
Thomas Heller1ce433e2006-08-14 16:20:04 +0000458- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
459 '-no-stack-protector' compiler flag for OpenBSD has been removed.
460
Thomas Heller86720042006-08-14 11:17:48 +0000461- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
462 uses the _as_parameter_ attribute when objects are passed to foreign
463 function calls. The ctypes version number was changed to 1.0.1.
464
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000465- Bug #1530559, struct.pack raises TypeError where it used to convert.
466 Passing float arguments to struct.pack when integers are expected
467 now triggers a DeprecationWarning.
468
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000469

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000500
Tim Peters4643c2f2006-08-10 22:45:34 +0000501C API
502-----
503
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000504- New API for Unicode rich comparisons: PyUnicode_RichCompare()
505
Tim Peters4643c2f2006-08-10 22:45:34 +0000506- Bug #1069160. Internal correctness changes were made to
507 ``PyThreadState_SetAsyncExc()``. A test case was added, and
508 the documentation was changed to state that the return value
509 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000512What's New in Python 2.5 beta 3?
513================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000514
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000515*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000516
517Core and builtins
518-----------------
519
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000520- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000521 returned a long (see PEP 353).
522
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000523- Bug #1515471: string.replace() accepts character buffers again.
524
Neal Norwitz07aadb12006-07-30 06:55:48 +0000525- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
526 This provides the proper warning for struct.pack().
527 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
528
Neal Norwitz0d62a062006-07-30 06:53:31 +0000529- Patch #1531113: Fix augmented assignment with yield expressions.
530 Also fix a SystemError when trying to assign to yield expressions.
531
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000532- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
533 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
534 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
535 excessive filesystem operations during imports.
536
Tim Petersbc24eee2006-07-27 01:14:53 +0000537- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
538 operations on signed longs that are formally undefined by C.
539 Unfortunately, at least one compiler now cares about that, so complicated
540 the code to make that compiler happy again.
541
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000542- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
543
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000544- Patch #1232023: Stop including current directory in search
545 path on Windows.
546
Neal Norwitze1fdb322006-07-21 05:32:28 +0000547- Fix some potential crashes found with failmalloc.
548
Neal Norwitze7563102006-07-17 01:00:16 +0000549- Fix warnings reported by Klocwork's static analysis tool.
550
Neal Norwitz84be93b2006-07-16 01:50:38 +0000551- Bug #1512814, Fix incorrect lineno's when code within a function
552 had more than 255 blank lines.
553
Georg Brandl9dceedb2006-07-12 15:31:17 +0000554- Patch #1521179: Python now accepts the standard options ``--help`` and
555 ``--version`` as well as ``/?`` on Windows.
556
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000557- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000558 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000559 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000560
Tim Peters112aad32006-07-19 00:03:19 +0000561- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000562 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000563 new ``sys._current_frames()`` returns a dictionary with one entry,
564 mapping the faux "thread id" 0 to the current frame.
565
Ronald Oussoren3075e162006-07-25 20:28:55 +0000566- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000567
Ronald Oussoren3075e162006-07-25 20:28:55 +0000568
Neal Norwitza1f10902006-07-12 07:28:29 +0000569Library
570-------
571
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000572- Correction of patch #1455898: In the mbcs decoder, set final=False
573 for stream decoder, but final=True for the decode function.
574
Georg Brandl07fec3a2006-08-01 18:49:24 +0000575- os.urandom no longer masks unrelated exceptions like SystemExit or
576 KeyboardInterrupt.
577
Tim Peters4643c2f2006-08-10 22:45:34 +0000578- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000579 shutil.copytree on Windows
580
Georg Brandle34ac7c2006-07-30 11:07:23 +0000581- Bug #1002398: The documentation for os.path.sameopenfile now correctly
582 refers to file descriptors, not file objects.
583
Tim Peterscbdd3502006-09-05 01:47:53 +0000584- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000585 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000586 #1513611, and probably others.
587
Georg Brandledd9b0d2006-07-29 09:33:26 +0000588- Bug #1441397: The compiler module now recognizes module and function
589 docstrings correctly as it did in Python 2.4.
590
Tim Peters6f681472006-07-27 23:44:37 +0000591- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
592 lost that tests are sorted by name before being run. This rarely
593 matters for well-written tests, but can create baffling symptoms if
594 side effects from one test to the next affect outcomes. ``DocTestFinder``
595 has been changed to sort the list of tests it returns.
596
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000597- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000598 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000599
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000600- Bug #978833: Really close underlying socket in _socketobject.close.
601
Georg Brandldb232dc2006-08-20 13:15:43 +0000602- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
603 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000604
Georg Brandlcf0c1722006-07-26 07:23:32 +0000605- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback

Martin v. Löwis0b483032006-07-25 09:53:12 +0000608- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
609
Georg Brandlc13c34c2006-07-24 14:09:56 +0000610- Patch #1515343: Fix printing of deprecated string exceptions with a
611 value in the traceback module.
612
Greg Ward48fae7a2006-07-23 16:05:51 +0000613- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
614
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000615- Patch #1524429: Use repr() instead of backticks in Tkinter again.
616
Brett Cannoncaebe222006-07-18 04:41:36 +0000617- Bug #1520914: Change time.strftime() to accept a zero for any position in its
618 argument tuple. For arguments where zero is illegal, the value is forced to
619 the minimum value that is correct. This is to support an undocumented but
620 common way people used to fill in inconsequential information in the time
621 tuple pre-2.4.
622
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000623- Patch #1220874: Update the binhex module for Mach-O.
624
Barry Warsawb110bad2006-07-21 14:51:07 +0000625- The email package has improved RFC 2231 support, specifically for
626 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
627 (name*0=<blah>) parameter continuations. This may change the types of
628 values returned from email.message.Message.get_param() and friends.
629 Specifically in some cases where non-encoded continuations were used,
630 get_param() used to return a 3-tuple of (None, None, string) whereas now it
631 will just return the string (since non-encoded continuations don't have
632 charset and language parts).
633
634 Also, whereas % values were decoded in all parameter continuations, they are
635 now only decoded in encoded parameter parts.
636
Ronald Oussoren3075e162006-07-25 20:28:55 +0000637- Bug #1517990: IDLE keybindings on MacOS X now work correctly
638
639- Bug #1517996: IDLE now longer shows the default Tk menu when a
640 path browser, class browser or debugger is the frontmost window on MacOS X
641
Barry Warsaw00decd72006-07-27 23:43:15 +0000642- Patch #1520294: Support for getset and member descriptors in types.py,
643 inspect.py, and pydoc.py. Specifically, this allows for querying the type
644 of an object against these built-in types and more importantly, for getting
645 their docstrings printed in the interactive interpreter's help() function.

650
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000651- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
652 a socket operation on a socket with a timeout, the exception will be
653 caught correctly. Previously, the exception was not caught.
654
Thomas Heller1393d6a2006-07-28 21:43:20 +0000655- Patch #1529514: The _ctypes extension is now compiled on more
656 openbsd target platforms.
657
Tim Peters9cab5932006-07-28 00:30:00 +0000658- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
659 a memory leak, affecting pickles and deep copies.
660
Tim Petersbc24eee2006-07-27 01:14:53 +0000661- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

665
Thomas Hellerce049a02006-07-14 17:51:14 +0000666- Patch #1521817: Index range checking on ctypes arrays containing
667 exactly one element enabled again. This allows iterating over these
668 arrays, without the need to check the array size before.
669
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000670- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000671 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000672 /dev/null in certain cases; this is now fixed.
673
Thomas Heller47d7a062006-07-12 08:43:47 +0000674- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
675 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000676
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000677- Because of a misspelled preprocessor symbol, ctypes was always
678 compiled without thread support; this is now fixed.
679
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000680- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
681 methods now allow their database parameter to be None as the
682 sleepycat API allows.
683
Matt Flemingec926502006-07-28 11:27:27 +0000684- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
685 bluetooth API compared with Linux and FreeBSD.

688-----
689
690- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
691 how long the test file should take to play. Now accepts taking 2.93 secs
692 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
693
Georg Brandl4793aa32006-07-28 18:31:39 +0000694- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
695 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
696 run via ``regrtest.py``. Now they do.

705
706- PythonLauncher now works correctly when the path to the script contains
707 characters that are treated specially by the shell (such as quotes).
708
709- Bug #1527397: PythonLauncher now launches scripts with the working directory
710 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000711 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000712 expect.

722
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000723- Bug #1441486: The literal representation of -(sys.maxint - 1)
724 again evaluates to a int object, not a long.
725
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000726- Bug #1501934: The scope of global variables that are locally assigned
727 using augmented assignment is now correctly determined.
728
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000729- Bug #927248: Recursive method-wrapper objects can now safely
730 be released.
731
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000732- Bug #1417699: Reject locale-specific decimal point in float()
733 and atof().
734
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000735- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
736 omit a default "error" argument for NULL pointer. This allows
737 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000738
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000739- Bug #1519018: 'as' is now validated properly in import statements.
740
Neal Norwitz28746ab2006-07-09 22:14:42 +0000741- On 64 bit systems, int literals that use less than 64 bits are
742 now ints rather than longs.
743
Neal Norwitzed657552006-07-10 00:04:44 +0000744- Bug #1512814, Fix incorrect lineno's when code at module scope
745 started after line 256.
746
Tim Peters32a83612006-07-10 21:08:24 +0000747- New function ``sys._current_frames()`` returns a dict mapping thread
748 id to topmost thread stack frame. This is for expert use, and is
749 especially useful for debugging application deadlocks. The functionality
750 was previously available in Fazal Majid's ``threadframe`` extension
751 module, but it wasn't possible to do this in a wholly threadsafe way from
752 an extension.

772 be treated as the value they contain, instead.
773
Martin v. Löwisede77f52006-07-03 13:01:35 +0000774- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

799
Brett Cannon53ab5b72006-06-22 16:49:14 +0000800- Bug #1510580: The 'warnings' module improperly required that a Warning
801 category be either a types.ClassType and a subclass of Warning. The proper
802 check is just that it is a subclass with Warning as the documentation states.
803
Georg Brandlad29e632006-06-21 17:45:17 +0000804- The compiler module now correctly compiles the new try-except-finally
805 statement (bug #1509132).
806
Neal Norwitz60373cd2006-06-22 06:30:50 +0000807- The wsgiref package is now installed properly on Unix.
808
Vinay Sajip28e57612006-07-01 10:45:20 +0000809- A bug was fixed in logging.config.fileConfig() which caused a crash on
810 shutdown when fileConfig() was called multiple times.
811
Gerhard Häring762fbd32006-07-02 17:48:30 +0000812- The sqlite3 module did cut off data from the SQLite database at the first
813 null character before sending it to a custom converter. This has been fixed
814 now.

Tim Peters112aad32006-07-19 00:03:19 +0000819- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
820 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
821 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000822
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000823- Assigning None to pointer type fields in ctypes structures possible
824 overwrote the wrong fields, this is fixed now.
825
826- Fixed a segfault in _ctypes when ctypes.wintypes were imported
827 on non-Windows platforms.
828
829- Bug #1518190: The ctypes.c_void_p constructor now accepts any
830 integer or long, without range checking.
831
832- Patch #1517790: It is now possible to use custom objects in the ctypes
833 foreign function argtypes sequence as long as they provide a from_param
834 method, no longer is it required that the object is a ctypes type.
835
836- The '_ctypes' extension module now works when Python is configured
837 with the --without-threads option.
838
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000839- Bug #1513646: os.access on Windows now correctly determines write

854
Tim Peters32a83612006-07-10 21:08:24 +0000855- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000856 Previously, the slight difference could cause compilation errors of the
857 'zlib' module on systems with more than one version of zlib.
858
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000859- The MSI compileall step was fixed to also support a TARGETDIR

892
Georg Brandla56b9152006-06-19 06:35:54 +0000893- Patch #1507676: Error messages returned by invalid abstract object operations
894 (such as iterating over an integer) have been improved and now include the
895 type of the offending object to help with debugging.
896
Brett Cannonea3912b2006-06-13 21:46:41 +0000897- Bug #992017: A classic class that defined a __coerce__() method that returned
898 its arguments swapped would infinitely recurse and segfault the interpreter.
899
Neal Norwitz909eb122006-06-12 02:13:21 +0000900- Fix the socket tests so they can be run concurrently.
901
Neal Norwitzb9845e72006-06-12 02:11:18 +0000902- Removed 5 integers from C frame objects (PyFrameObject).

Brett Cannon22565aa2006-06-09 22:31:23 +0000905- Bug #532646: object.__call__() will continue looking for the __call__
906 attribute on objects until one without one is found. This leads to recursion
907 when you take a class and set its __call__ attribute to an instance of the
908 class. Originally fixed for classic classes, but this fix is for new-style.
909 Removes the infinite_rec_3 crasher.
910
Georg Brandl24250812006-06-09 18:45:48 +0000911- The string and unicode methods startswith() and endswith() now accept
912 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
913
Brett Cannonde3b0522006-06-08 17:00:45 +0000914- Buffer objects, at the C level, never used the char buffer
915 implementation even when the char buffer for the wrapped object was
916 explicitly requested (originally returned the read or write buffer).
917 Now a TypeError is raised if the char buffer is not present but is
918 requested.
919
Georg Brandlddbaa662006-06-04 21:56:52 +0000920- Patch #1346214: Statements like "if 0: suite" are now again optimized
921 away like they were in Python 2.4.
922
Georg Brandlb7c8f542006-05-27 12:30:25 +0000923- Builtin exceptions are now full-blown new-style classes instead of
924 instances pretending to be classes, which speeds up exception handling
925 by about 80% in comparison to 2.5a2.
926
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000927- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
928 Unicode 4.1.
929
Georg Brandlf4ef1162006-05-26 18:03:31 +0000930- Patch #921466: sys.path_importer_cache is now used to cache valid and
931 invalid file paths for the built-in import machinery which leads to
932 fewer open calls on startup.
933
Tim Peters696cf432006-05-24 21:10:40 +0000934- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
935 of-2 bases. The largest speedup is for inputs with about 1000 decimal
936 digits. Conversion from non-power-of-2 bases remains quadratic-time in
937 the number of input digits (it was and remains linear-time for bases
938 2, 4, 8, 16 and 32).
939
Tim Petersb713ec22006-05-23 18:45:30 +0000940- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
941 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
942 an integer close to ``sys.maxint``. This was repaired by patch
943 #1335972, which also gives a nice speedup.
944
Richard Jonescebbefc2006-05-23 18:28:17 +0000945- Patch #1337051: reduced size of frame objects.
946
947- PyErr_NewException now accepts a tuple of base classes as its
948 "base" parameter.
949
Richard Jones7c88dcc2006-05-23 10:37:38 +0000950- Patch #876206: function call speedup by retaining allocated frame
951 objects.
952
Georg Brandl7b90e162006-05-18 07:01:27 +0000953- Bug #1462152: file() now checks more thoroughly for invalid mode
954 strings and removes a possible "U" before passing the mode to the
955 C library function.
956
Neal Norwitz1004a532006-05-15 07:17:23 +0000957- Patch #1488312, Fix memory alignment problem on SPARC in unicode
958
Neal Norwitz373f0a72006-05-15 07:04:36 +0000959- Bug #1487966: Fix SystemError with conditional expression in assignment
960
Martin v. Löwis879768d2006-05-11 13:28:43 +0000961- WindowsError now has two error code attributes: errno, which carries
962 the error values from errno.h, and winerror, which carries the error
963 values from winerror.h. Previous versions put the winerror.h values
964 (from GetLastError()) into the errno attribute.
965
Martin v. Löwis77736712006-05-04 05:51:03 +0000966- Patch #1475845: Raise IndentationError for unexpected indent.
967
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000968- Patch #1479181: split open() and file() from being aliases for each other.
969
Tim Peters44bd9862006-06-01 13:49:23 +0000970- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
971 methods were always silently ignored by dictionaries when comparing keys.
972 They are now passed through (except when using the C API function
973 ``PyDict_GetItem()``, whose semantics did not change).
974
975- Bug #1456209: In some obscure cases it was possible for a class with a
976 custom ``__eq__()`` method to confuse dict internals when class instances
977 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
978 No, you don't have any code that did this ;-)

981-----------------
982
Trent Mick960a3f82006-06-28 20:30:41 +0000983- Bug #1295808: expat symbols should be namespaced in pyexpat
984
985- Patch #1462338: Upgrade pyexpat to expat 2.0.0
986
Brett Cannon6ee7d012006-06-08 16:23:04 +0000987- Change binascii.hexlify to accept a read-only buffer instead of only a char
988 buffer and actually follow its documentation.
989
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000990- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
991
Nick Coghlanc649ec52006-05-29 12:43:05 +0000992- Patch #1478788 (modified version): The functional extension module has
993 been renamed to _functools and a functools Python wrapper module added.
994 This provides a home for additional function related utilities that are
995 not specifically about functional programming. See PEP 309.
996
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000997- Patch #1493701: performance enhancements for struct module.
998
Georg Brandl378d5922006-05-17 14:26:50 +0000999- Patch #1490224: time.altzone is now set correctly on Cygwin.
1000
Georg Brandl8d3342b2006-05-16 07:38:27 +00001001- Patch #1435422: zlib's compress and decompress objects now have a
1002 copy() method.
1003
Andrew MacIntyre92913322006-06-13 15:04:24 +00001004- Patch #1454481: thread stack size is now tunable at runtime for thread
1005 enabled builds on Windows and systems with Posix threads support.
1006
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001007- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1008 (up to the system limit of 32K characters).
1009
1010- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1011 As a result, these functions now raise WindowsError instead of OSError.
1012
Tim Peters7a822da2006-05-25 21:50:17 +00001013- ``time.clock()`` on Win64 should use the high-performance Windows
1014 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1015 Windows platforms).
1016
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001017- Calling Tk_Init twice is refused if the first call failed as that
1018 may deadlock.
1019
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001020- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1021 accept it without potentially using an uninitialized pointer.
1022
1023- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1024 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1025 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001026
Gregory P. Smith372b5832006-06-05 18:48:21 +00001027- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001028 [pybsddb project SF patch number 1466734]
1029
Gregory P. Smith372b5832006-06-05 18:48:21 +00001030- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1031 parameter is supplied. [SF pybsddb bug #1477863]
1032
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001033- bsddb: the __len__ method of a DB object has been fixed to return correct
1034 results. It could previously incorrectly return 0 in some cases.
1035 Fixes SF bug 1493322 (pybsddb bug 1184012).
1036
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001037- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1038 aborts the db transaction safely when a modifier callback fails.
1039 Fixes SF python patch/bug #1408584.
1040
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001041- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001042 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001043 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1044 database calls that would previously deadlock. [SF python bug #775414]
1045
Vinay Sajip28e57612006-07-01 10:45:20 +00001046- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001054- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1055 functions.
1056
Martin v. Löwis3798da02006-06-17 18:44:27 +00001057- Patch #812986: Update turtle output even if not tracing.
1058
Vinay Sajip28e57612006-07-01 10:45:20 +00001059- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001060 Tkinter.BaseWidget.
1061
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001062- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1063
Martin v. Löwis337487e2006-06-17 09:15:14 +00001064- Patch #763580: Add name and value arguments to Tkinter variable
1065 classes.
1066
Georg Brandl83cc0d02006-06-14 08:50:03 +00001067- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1068 mime.types file for determining MIME types.
1069
Georg Brandl2605ca82006-06-14 06:08:31 +00001070- Bug #1339007: Shelf objects now don't raise an exception in their
1071 __del__ method when initialization failed.
1072
Martin v. Löwisd8251432006-06-14 05:21:04 +00001073- Patch #1455898: The MBCS codec now supports the incremental mode for
1074 double-byte encodings.
1075
Tim Peters43898b42006-06-14 04:09:25 +00001076- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1077 guarantee that adjacent triples in the return list always describe
1078 non-adjacent blocks. Previously, a pair of matching blocks could end
1079 up being described by multiple adjacent triples that formed a partition
1080 of the matching pair.
1081
Greg Ward0e0c9f42006-06-11 16:24:11 +00001082- Bug #1498146: fix optparse to handle Unicode strings in option help,
1083 description, and epilog.
1084
Greg Wardd1c797e2006-06-11 14:42:41 +00001085- Bug #1366250: minor optparse documentation error.
1086
Greg Ward7f547402006-06-11 00:40:49 +00001087- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1088 clarify docs.
1089
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001090- The wsgiref package has been added to the standard library.
1091
Nick Coghlan676725d2006-06-08 13:54:49 +00001092- The functions update_wrapper() and wraps() have been added to the functools
1093 module. These make it easier to copy relevant metadata from the original
1094 function when writing wrapper functions.
1095
Tim Petersd6a9eef2006-06-05 01:48:21 +00001096- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1097 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001098
Martin v. Löwis3f767792006-06-04 19:36:28 +00001099- Patch #1359618: Speed up charmap encoder by using a trie structure
1100 for lookup.
1101
Tim Petersd609b1a2006-06-02 23:22:51 +00001102- The functions in the ``pprint`` module now sort dictionaries by key
1103 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1104 if and only if its display required more than one line, although that
1105 wasn't documented. The new behavior increases predictability; e.g.,
1106 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1107
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001108- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1109 (thanks for J. J. Lee).
1110
Georg Brandl2b330372006-05-28 20:23:12 +00001111- Patch #1496206: improve urllib2 handling of passwords with respect to
1112 default HTTP and HTTPS ports.
1113
George Yoshidaf3c65de2006-05-28 16:39:09 +00001114- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1115
Bob Ippolito7298f272006-05-23 18:43:47 +00001116- Patch #1281707: speed up gzip.readline.
1117
Georg Brandlb89316f2006-05-17 15:51:16 +00001118- Patch #1180296: Two new functions were added to the locale module:
1119 format_string() to get the effect of "format % items" but locale-aware,
1120 and currency() to format a monetary number with currency sign.
1121
Georg Brandle3a25832006-05-17 14:56:04 +00001122- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1123 and several features added, such as speed and geometry control.
1124
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001125- Patch #1488881: add support for external file objects in bz2 compressed
1126 tarfiles.
1127
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001128- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1129 stdout arguments, making it possible to redirect input and output
1130 for remote debugging.
1131
1132- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1133 a couple of issues, notably handling of long file names using the
1134 GNU LONGNAME extension.
1135
1136- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1137 new flag when ``name`` is already the name of an option flag.
1138
1139- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1140 package.
1141
1142- Patch #1472854: make the rlcompleter.Completer class usable on non-
1143 UNIX platforms.
1144
1145- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1146
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001147- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001178What's New in Python 2.5 alpha 2?
1179=================================
1180
1181*Release date: 27-APR-2006*
1182
1183Core and builtins
1184-----------------
1185
Thomas Heller1b046642006-04-18 18:51:06 +00001186- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1187 by converting these apis from macros into exported functions again:
1188
1189 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1190 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1191 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1192 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1193 PyRun_String Py_CompileString
1194
Martin v. Löwis45294a92006-04-18 06:24:08 +00001195- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1196
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001197- All uses of PyStructSequence_InitType have been changed to initialize
1198 the type objects only once, even if the interpreter is initialized
1199 multiple times.
1200
Neal Norwitz61546162006-04-14 05:20:28 +00001201- Bug #1454485, array.array('u') could crash the interpreter. This was
1202 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1203 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1204
1205- Py_UNICODE is unsigned. It was always documented as unsigned, but
1206 due to a bug had a signed value in previous versions.
1207
Tim Peters3a5e8b12006-04-11 01:44:07 +00001208- Patch #837242: ``id()`` of any Python object always gives a positive
1209 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1210 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001211 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001212 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001213
Tim Peters3a5e8b12006-04-11 01:44:07 +00001214 def __hash__(self):
1215 return id(self) # WRONG
1216
1217 because a hash result must be a (short) Python int but it was always
1218 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001219 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001220 was always usable as a hash value before this patch. That's no longer
1221 necessarily so.
1222
1223- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001224 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001225 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001226 #1454844)
1227
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001228- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1229 involving generators that have paused outside of any ``try`` or ``with``
1230 blocks. (In 2.5a1, a paused generator that was part of a reference
1231 cycle could not be garbage collected, regardless of whether it was
1232 paused in a ``try`` or ``with`` block.)

1245- Bug #1117761: bsddb.*open() no longer raises an exception when using
1246 the cachesize parameter.
1247
1248- Bug #1149413: bsddb.*open() no longer raises an exception when using
1249 a temporary db (file=None) with the 'n' flag to truncate on open.
1250
1251- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1252 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001253
Armin Rigoa9017c32006-04-19 11:50:27 +00001254- Patch #1062014: AF_UNIX sockets under Linux have a special

1259
Peter Astrand7d1d4362006-07-14 14:04:45 +00001260- Bug #1223937: subprocess.CalledProcessError reports the exit status
1261 of the process using the returncode attribute, instead of
1262 abusing errno.
1263
Tim Peters711bf302006-04-25 03:31:36 +00001264- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1265 a doctest to be skipped (the code is not run, and the expected output
1266 or exception is ignored).
1267
Nick Coghlanda2268f2006-04-24 04:37:15 +00001268- Fixed contextlib.nested to cope with exceptions being raised and
1269 caught inside exit handlers.
1270
Greg Wardab05edc2006-04-23 03:47:58 +00001271- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1272 hex, octal, or binary; add ``append_const`` action; keep going if
1273 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1274 added ``epilog`` for better help generation).
1275
Tim Peters21fbd572006-04-21 21:18:10 +00001276- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1277 called from a thread spawned as a side effect of importing a module.
1278
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001279- The pydoc module now supports documenting packages contained in
1280 .zip or .egg files.
1281
1282- The pkgutil module now has several new utility functions, such
1283 as ``walk_packages()`` to support working with packages that are either
1284 in the filesystem or zip files.
1285
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001286- The mailbox module can now modify and delete messages from
1287 mailboxes, in addition to simply reading them. Thanks to Gregory
1288 K. Johnson for writing the code, and to the 2005 Google Summer of
1289 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001290

Skip Montanaro262fb922006-04-21 02:31:07 +00001314- The pstats.Stats class accepts an optional stream keyword argument to
1315 direct output to an alternate file-like object.
1316
Anthony Baxter51bcb682006-04-05 14:51:42 +00001317Build
1318-----
1319
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001320- The Makefile now has a reindent target, which runs reindent.py on
1321 the library.
1322
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001323- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001326
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001327- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1328 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001329 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001330 CXX from --with-cxx-main, see description in README.
1331
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001332- Patch #1429775: Link extension modules with the shared libpython.
1333
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001334- Fixed a libffi build problem on MIPS systems.
1335
Tim Peters8931ff12006-05-13 23:28:20 +00001336- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1337 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1338 and "%zu" for unsigned integers of type ``size_t``.
1339
Anthony Baxter51bcb682006-04-05 14:51:42 +00001340Tests
1341-----
1342
Nick Coghlanda2268f2006-04-24 04:37:15 +00001343- test_contextlib now checks contextlib.nested can cope with exceptions
1344 being raised and caught inside exit handlers.
1345
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001346- test_cmd_line now checks operation of the -m and -c command switches
1347
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001348- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1349 it separately and by hand. It also wasn't cleaning up its changes to
1350 the current Decimal context.
1351
Thomas Woutersabd08882006-04-26 15:53:30 +00001352- regrtest.py now has a -M option to run tests that test the new limits of
1353 containers, on 64-bit architectures. Running these tests is only sensible
1354 on 64-bit machines with more than two gigabytes of memory. The argument
1355 passed is the maximum amount of memory for the tests to use.

1364-------------
1365
Tim Petersb06d28c2006-05-12 01:57:59 +00001366- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1367
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001368- PEP 343: Added Context Types section to the library reference
1369 and attempted to bring other PEP 343 related documentation into
1370 line with the implementation and/or python-dev discussions.
1371
Tim Peters8dc73d22006-04-24 02:03:16 +00001372- Bug #1337990: clarified that ``doctest`` does not support examples
1373 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001376What's New in Python 2.5 alpha 1?
1377=================================
1378
Anthony Baxterebed3f62006-04-03 15:03:44 +00001379*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001380
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001381Core and builtins
1382-----------------
1383
Nick Coghlan43832302006-04-23 17:04:07 +00001384- PEP 338: -m command line switch now delegates to runpy.run_module
1385 allowing it to support modules in packages and zipfiles
1386
Martin v. Löwisc661b882006-04-20 04:54:23 +00001387- On Windows, .DLL is not an accepted file name extension for
1388 extension modules anymore; extensions are only found if they
1389 end in .PYD.
1390
Martin v. Löwisea62d252006-04-03 10:56:49 +00001391- Bug #1421664: sys.stderr.encoding is now set to the same value as
1392 sys.stdout.encoding.
1393
Neal Norwitz92e212f2006-04-03 04:48:37 +00001394- __import__ accepts keyword arguments.
1395
Georg Brandlccadf842006-03-31 18:54:53 +00001396- Patch #1460496: round() now accepts keyword arguments.
1397
Anthony Baxter262c00a2006-03-30 10:53:17 +00001398- Fixed bug #1459029 - unicode reprs were double-escaped.
1399
Hye-Shik Changd478f342006-03-23 12:32:36 +00001400- Patch #1396919: The system scope threads are reenabled on FreeBSD
1401 5.4 and later versions.
1402
Neal Norwitze98ccf62006-03-23 05:39:47 +00001403- Bug #1115379: Compiling a Unicode string with an encoding declaration
1404 now gives a SyntaxError.
1405
Georg Brandlabd1ff82006-03-18 07:59:59 +00001406- Previously, Python code had no easy way to access the contents of a
1407 cell object. Now, a ``cell_contents`` attribute has been added
1408 (closes patch #1170323).
1409
Tim Peterscf79aac2006-03-16 01:14:46 +00001410- Patch #1123430: Python's small-object allocator now returns an arena to
1411 the system ``free()`` when all memory within an arena becomes unused
1412 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1413 freed. Some applications will see a drop in virtual memory size now,
1414 especially long-running applications that, from time to time, temporarily
1415 use a large number of small objects. Note that when Python returns an
1416 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001417 platform C library will in turn return that memory to the operating system.
1418 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001419 appears to be effective at least on Microsoft C and gcc-based systems.
1420 Thanks to Evan Jones for hard work and patience.
1421
Georg Brandl533ff6f2006-03-08 18:09:27 +00001422- Patch #1434038: property() now uses the getter's docstring if there is
1423 no "doc" argument given. This makes it possible to legitimately use
1424 property() as a decorator to produce a read-only property.
1425
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001426- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1427 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1428 of requiring an int or long in slicing and a few other contexts, enabling
1429 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1430
Neal Norwitz995acdf2006-03-07 05:01:00 +00001431- Fixed various bugs reported by Coverity's Prevent tool.
1432
Brett Cannonbf364092006-03-01 04:25:17 +00001433- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1434 new exception base class, BaseException, which has a new message attribute.
1435 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1436 Raising a string exception now raises a DeprecationWarning.
1437
Thomas Woutersfb609f42006-02-28 16:37:25 +00001438- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1439 explicitly relative, using 'from .module import name' to mean 'from the same
1440 package as this module is in. Imports without dots still default to the
1441 old relative-then-absolute, unless 'from __future__ import
1442 absolute_import' is used.
1443
Brett Cannona7446e32006-02-27 23:39:10 +00001444- Properly check if 'warnings' raises an exception (usually when a filter set
1445 to "error" is triggered) when raising a warning for raising string
1446 exceptions.
1447
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001448- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001449 The name was removed from Include/code.h.
1450
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001451- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001452
Guido van Rossum1968ad32006-02-25 22:38:04 +00001453- Patch 1433928:
1454 - The copy module now "copies" function objects (as atomic objects).
1455 - dict.__getitem__ now looks for a __missing__ hook before raising
1456 KeyError.
1457
Tim Peters84ef21c2006-02-28 20:39:06 +00001458- PEP 343: with statement implemented. Needs ``from __future__ import
1459 with_statement``. Use of 'with' as a variable will generate a warning.
1460 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001461 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001462 The following objects have __context__ methods:
1463 - The built-in file type.
1464 - The thread.LockType type.
1465 - The following types defined by the threading module:
1466 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1467 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001468
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001469- Fix the encodings package codec search function to only search
1470 inside its own package. Fixes problem reported in patch #1433198.
1471
1472 Note: Codec packages should implement and register their own
1473 codec search function. PEP 100 has the details.
1474
Tim Peters9ea89d22006-06-04 03:26:02 +00001475- PEP 353: Using ``Py_ssize_t`` as the index type.
1476
1477- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1478 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1479 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1480 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1481 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001482
Neal Norwitzfc76d632006-01-10 06:03:13 +00001483- Patch #1400181, fix unicode string formatting to not use the locale.
1484 This is how string objects work. u'%f' could use , instead of .
1485 for the decimal point. Now both strings and unicode always use periods.
1486
Neal Norwitz671b9e32006-01-09 07:07:12 +00001487- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1488 configure would break checking curses.h.
1489
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001490- Bug #959576: The pwd module is now builtin. This allows Python to be
1491 built on UNIX platforms without $HOME set.
1492
Neal Norwitzc10978f2005-12-19 06:07:16 +00001493- Bug #1072182, fix some potential problems if characters are signed.
1494
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001495- Bug #889500, fix line number on SyntaxWarning for global declarations.
1496
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001497- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1498
Neal Norwitze7214a12005-12-18 05:03:17 +00001499- Support for converting hex strings to floats no longer works.
1500 This was not portable. float('0x3') now raises a ValueError.
1501
Barry Warsaw2a38a862005-12-18 01:27:35 +00001502- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001503 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001504 is now displayed in interactive prompt banner.
1505
Georg Brandlfa166682005-12-17 21:45:17 +00001506- Implementation of PEP 341 - Unification of try/except and try/finally.
1507 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001508 one try statement instead of two nested ones. Patch #1355913.

Hye-Shik Chang835b2432005-12-17 04:38:31 +00001510- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1511 now encodes backslash correctly.
1512
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001513- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1514
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001515- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001516 and long longs.
1517
Neal Norwitz67715f02005-11-09 06:59:35 +00001518- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001519 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001520 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001521
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001522- Replaced most Unicode charmap codecs with new ones using the
1523 new Unicode translate string feature in the builtin charmap
1524 codec; the codecs were created from the mapping tables available
1525 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1526 encodings now include a mapping for the Apple logo)
1527
Tim Peterse3547fd2005-12-16 23:13:57 +00001528- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001529
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001530- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001531
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001532- A new AST parser implementation was completed. The abstract
1533 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001534 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001535
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001536- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001537 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1538
Neal Norwitz708e51a2005-10-03 04:48:15 +00001539- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1540
Neal Norwitz11bd1192005-10-03 00:54:56 +00001541- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1542 Provide a warning when a directory is passed on the command line.
1543
Neal Norwitz40d37812005-10-02 01:48:49 +00001544- Fix segfault with invalid coding.
1545
1546- SF bug #772896: unknown encoding results in MemoryError.
1547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001548- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001549 supported a __len__() method which evaluated to False when the iterator
1550 was empty.
1551
Guido van Rossum630db602005-09-20 18:49:54 +00001552- On 64-bit platforms, when __len__() returns a value that cannot be
1553 represented as a C int, raise OverflowError.
1554
Skip Montanarof8948ca2005-09-19 03:54:46 +00001555- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001556 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001557
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001558- SF bug #893549: parsing keyword arguments was broken with a few format
1559 codes.
1560
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001561- Changes donated by Elemental Security to make it work on AIX 5.3
1562 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1563 bug #105470: test_pwd fails on 64bit system (Opteron).
1564
Guido van Rossum539c6622005-09-14 17:49:54 +00001565- Changes donated by Elemental Security to make it work on HP-UX 11 on
1566 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1567
Georg Brandl4550b8d2005-08-26 06:43:52 +00001568- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001569 (fixes bug #1119418).
1570
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001571- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1572
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001573- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1574 exceptions that cause a function to exit.
1575
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001576- The implementation of set() and frozenset() was revised to use its
1577 own internal data structure. Memory consumption is reduced by 1/3
1578 and there are modest speed-ups as well. The API is unchanged.
1579
Tim Petersde7990b2005-07-17 23:45:23 +00001580- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1581
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001582- SF bug #1229429: PyObject_CallMethod failed to decrement some
1583 reference counts in some error exit cases.
1584
Tim Petersecc6e6a2005-07-10 22:30:55 +00001585- SF bug #1185883: Python's small-object memory allocator took over
1586 a block managed by the platform C library whenever a realloc specified
1587 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001588 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001589 portable way to copy data from the C-managed block into Python's
1590 small-object space without risking a memory fault. Python's small-object
1591 realloc now leaves such blocks under the control of the platform C
1592 realloc.
1593
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001594- SF bug #1232517: An overflow error was not detected properly when
1595 attempting to convert a large float to an int in os.utime().
1596
Raymond Hettinger3296e692005-06-29 23:29:56 +00001597- SF bug #1224347: hex longs now print with lowercase letters just
1598 like their int counterparts.
1599
Michael W. Hudson188d4362005-06-20 16:52:57 +00001600- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1601 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1602 interpreter states; back out that fix and do a better job (see
1603 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1604 for a longer write-up of the problem).
1605
Michael W. Hudsondf888462005-06-03 14:41:55 +00001606- SF patch #1180995: marshal now uses a binary format by default when
1607 serializing floats.
1608
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001609- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1610 the routines that promise to produce IEEE 754 binary representations
1611 of floats now simply copy bytes around.
1612
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001613- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1614 278.
1615
Brett Cannonc3647ac2005-04-26 03:45:26 +00001616- patch #1109424: int, long, float, complex, and unicode now check for the
1617 proper magic slot for type conversions when subclassed. Previously the
1618 magic slot was ignored during conversion. Semantics now match the way
1619 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001620 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001621 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001622 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001623
Barry Warsawc8d907c2005-04-19 23:43:40 +00001624- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1625 NULL, now raise an AttributeError when attempting to set or delete the
1626 attribute. Previously a TypeError was raised, but this was inconsistent
1627 with the equivalent pure-Python implementation.
1628
Michael W. Hudson774479c2005-04-18 08:46:17 +00001629- It is now safe to call PyGILState_Release() before
1630 PyEval_InitThreads() (note that if there is reason to believe there
1631 are multiple threads around you still must call PyEval_InitThreads()
1632 before using the Python API; this fix is for extension modules that
1633 have no way of knowing if Python is multi-threaded yet).
1634
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001635- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1636 disabled caused a crash.
1637
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001638- Bug #1165306: instancemethod_new allowed the creation of a method
1639 with im_class == im_self == NULL, which caused a crash when called.
1640
Tim Petersecc6e6a2005-07-10 22:30:55 +00001641- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001642 fixes the crash seen in bug #1165761
1643
Raymond Hettinger96229b12005-03-11 06:49:40 +00001644- Added two new builtins, any() and all().
1645
Brett Cannon409d8f22005-03-05 06:47:57 +00001646- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001647 (e.g., ``class C(): pass`` is no longer a syntax error).
1648 Patch #1176012 added support to the 'parser' module and 'compiler' package
1649 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001650
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001651- Patch #1115086: Support PY_LONGLONG in structmember.
1652
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001653- Bug #1155938: new style classes did not check that __init__() was
1654 returning None.
1655
Tim Petersecc6e6a2005-07-10 22:30:55 +00001656- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001657 ('\') with a specific error message.
1658
Martin v. Löwisff232d72005-03-03 09:24:38 +00001659- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1660
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001661- Bug #1124295: the __name__ attribute of file objects was
1662 inadvertently made inaccessible in restricted mode.
1663
Tim Petersecc6e6a2005-07-10 22:30:55 +00001664- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001665 an ferror() call.
1666
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001667- min() and max() now support key= arguments with the same meaning as in
1668 list.sort().
1669
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001670- The peephole optimizer now performs simple constant folding in expressions:
1671 (2+3) --> (5).
1672
Raymond Hettingera422c342005-01-11 03:03:27 +00001673- set and frozenset objects can now be marshalled. SF #1098985.
1674
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001675- Bug #1077106: Poor argument checking could cause memory corruption
1676 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001677
Jeremy Hyltonab630502005-02-04 18:44:06 +00001678- The parser did not complain about future statements in illegal
1679 positions. It once again reports a syntax error if a future
1680 statement occurs after anything other than a doc string.
1681
Neil Schemenauercf52c072005-08-12 17:34:58 +00001682- Change the %s format specifier for str objects so that it returns a
1683 unicode instance if the argument is not an instance of basestring and
1684 calling __str__ on the argument returns a unicode instance.
1685
Tim Petersf4e69282006-02-27 17:15:31 +00001686- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1687 current thread state when the auto-GIL-state machinery knows about
1688 it (since the thread state is being deleted, continuing to remember it
1689 can't help, but can hurt if another thread happens to get created with
1690 the same thread id).
1691
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001692Extension Modules
1693-----------------
1694
Georg Brandl43f08a82006-03-31 18:01:16 +00001695- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00001704
Neal Norwitz10be10c2006-03-16 06:50:13 +00001705- Everything under lib-old was removed. This includes the following modules:
1706 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001707 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001708 util, whatsound, whrandom, zmod
1709
1710- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1711
1712- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001713 is deprecated. The undocumented re.engine variable no longer exists.
1714
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001715- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1716 SS2 (single-shift 2) escape sequences correctly.
1717
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001718- The unicodedata module was updated to the 4.1 version of the Unicode
1719 database. The 3.2 version is still available as unicodedata.db_3_2_0
1720 for applications that require this specific version (such as IDNA).
1721
Neal Norwitzb62c4332006-03-04 18:35:47 +00001722- The timing module is no longer built by default. It was deprecated
1723 in PEP 4 in Python 2.0 or earlier.
1724
Guido van Rossum1968ad32006-02-25 22:38:04 +00001725- Patch 1433928: Added a new type, defaultdict, to the collections module.
1726 This uses the new __missing__ hook behavior added to dict (see above).
1727
Georg Brandldbd83392006-02-20 09:42:33 +00001728- Bug #854823: socketmodule now builds on Sun platforms even when
1729 INET_ADDRSTRLEN is not defined.
1730
Georg Brandlf4f44152006-02-18 22:29:33 +00001731- Patch #1393157: os.startfile() now has an optional argument to specify
1732 a "command verb" to invoke on the file.
1733
Neal Norwitz082b2df2006-02-07 07:04:46 +00001734- Bug #876637, prevent stack corruption when socket descriptor
1735 is larger than FD_SETSIZE.
1736
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001737- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1738 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1739 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1740
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001741- Patch #1422385: The nis module now supports access to domains other
1742 than the system default domain.
1743
Martin v. Löwis14694662006-02-03 12:54:16 +00001744- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1745 are reported, the limit on path name lengths is removed, and stat reports
1746 WindowsError now (instead of OSError).
1747
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001748- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1749
Neal Norwitz62a21122006-01-25 05:21:55 +00001750- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1751 before the env.
1752

1758 Also fix ungetmouse() which did not accept arguments properly.
1759 The code now conforms to the documented signature.
1760
Neal Norwitz5e3d8622006-01-09 06:24:35 +00001761- Bug #1400115, Fix segfault when calling curses.panel.userptr()
1762 without prior setting of the userptr.
1763

1823 the request code argument, which results in more C-like behaviour
1824 for large or negative values.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001882- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1883 been renamed to have only a single underscore prefix. This was done to
1884 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001885
Nick Coghlan43832302006-04-23 17:04:07 +00001886- PEP 338: new module runpy defines a run_module function to support
1887 executing modules which provide access to source code or a code object
1888 via the PEP 302 import mechanisms.
1889
Anthony Baxter93f5b932006-04-03 08:05:07 +00001890- The email module's parsedate_tz function now sets the daylight savings

1898 in attribute values.
1899
Anthony Baxterc51ee692006-04-01 00:57:31 +00001900- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001901 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001902 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001903 module will not be built.
1904
Tim Petersc17976e2006-04-01 00:26:53 +00001905- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1906 aren't officially supported here, and trying to use them will probably
1907 raise an exception some day. But dicts have been allowed, and "mostly
1908 worked", so support for them won't go away without warning.
1909
Georg Brandl338ef7d2006-03-31 18:42:16 +00001910- Bug #1445068: getpass.getpass() can now be given an explicit stream
1911 argument to specify where to write the prompt.
1912

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001921- Queue.Queue objects now support .task_done() and .join() methods
1922 to make it easier to monitor when daemon threads have completed
1923 processing all enqueued tasks. Patch #1455676.
1924

1928
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001929- email 4.0 package now integrated. This is largely the same as the email 3.0
1930 package that was included in Python 2.3, except that PEP 8 module names are
1931 now used (e.g. mail.message instead of email.Message). The MIME classes
1932 have been moved to a subpackage (e.g. email.mime.text instead of
1933 email.MIMEText). The old names are still supported for now. Several
1934 deprecated Message methods have been removed and lots of bugs have been
1935 fixed. More details can be found in the email package documentation.
1936
Walter Dörwald40108c92006-03-27 08:15:44 +00001937- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1938 (a subclass of tuple) that provides incremental decoders and encoders
1939 (a way to use stateful codecs without the stream API). Python functions
1940 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1941 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1942 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001943
Walter Dörwald067db482006-03-15 22:17:27 +00001944- Patch #1359365: Calling next() on a closed StringIO.String object raises
1945 a ValueError instead of a StopIteration now (like file and cString.String do).
1946 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1947 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001948
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001949- A regrtest option -w was added to re-run failed tests in verbose mode.

1959
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001960- PEP 343: new module contextlib.py defines decorator @contextmanager
1961 and helpful context managers nested() and closing().
1962

Martin v. Löwis3e865952006-01-24 15:51:21 +00001997 specifications, raises IOErrors when proxies for unsupported protocols
1998 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002021 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2022 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2023 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2024 Ronald L. Rivest offered this advice for Python:
2025
2026 "The consensus of researchers in this area (at least as
2027 expressed at the NIST Hash Function Workshop 10/31/05),
2028 is that SHA-256 is a good choice for the time being, but
2029 that research should continue, and other alternatives may
2030 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002031
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002032- Added a subset of Fredrik Lundh's ElementTree package. Available

2085 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002086 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002087

2109 to W3C name (404 -> 'Not Found'). RFE #1216944.
2110
Georg Brandl9e43acf2005-07-04 17:16:07 +00002111- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2112 as this can cause problems with apps closing all file descriptors.

2125 Bug #1224621.
2126
Raymond Hettinger68c04532005-06-10 11:05:19 +00002127- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002128 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002129 the generate_tokens() function now accepts a callable argument that
2130 terminates by raising StopIteration.
2131
Georg Brandl9166e1a2005-06-04 09:20:03 +00002132- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2133
Georg Brandl268e61c2005-06-03 14:28:50 +00002134- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

2136
Skip Montanaro174dd222005-05-14 20:54:16 +00002137- Patch #1120353: The xmlrpclib module provides better, more transparent,

2139 to True, applications shouldn't have to fiddle with the DateTime wrapper
2140 class at all.
2141
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002142- distutils.commands.upload was added to support uploading distribution
2143 files to PyPI.
2144
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002145- distutils.commands.register now encodes the data as UTF-8 before posting
2146 them to PyPI.
2147
Raymond Hettinger267b8682005-03-27 10:47:39 +00002148- decimal operator and comparison methods now return NotImplemented
2149 instead of raising a TypeError when interacting with other types. This
2150 allows other classes to implement __radd__ style methods and have them
2151 work as expected.
2152
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002153- Bug #1163325: Decimal infinities failed to hash. Attempting to
2154 hash a NaN raised an InvalidOperation instead of a TypeError.
2155
Tim Petersecc6e6a2005-07-10 22:30:55 +00002156- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2190
Guido van Rossumd0641422005-02-03 15:01:24 +00002191- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2192 disables recursive traversal through instance attributes, which can
2193 be exploited in various ways.
2194
Tim Peterse3547fd2005-12-16 23:13:57 +00002195- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002196 flags on the HTTP listening socket.
2197
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002198- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2199 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2200
Fred Drakefbdeaad2006-07-29 16:56:15 +00002201- Patches #893642, #1039083: add allow_none, encoding arguments to
2202 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002203
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002204- Bug #1110478: Revert os.environ.update to do putenv again.
2205
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002206- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2207
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002208- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2209
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002210- Enhancements to the csv module:
2211
2212 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002213 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002214 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002215 + Dialect parameter parsing has been re-implemented to improve error
2216 reporting.
2217 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2218 dictates.
2219 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002220 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002221 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002222 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2223 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002224 + reader now allows \r characters to be quoted (previously it only allowed
2225 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002226 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002227 + Dialect classes passed to the module are no longer instantiated by
2228 the module before being parsed (the former validation scheme required
2229 this, but the mechanism was unreliable).
2230 + The dialect registry now contains instances of the internal
2231 C-coded dialect type, rather than references to python objects.
2232 + the internal c-coded dialect type is now immutable.
2233 + register_dialect now accepts the same keyword dialect specifications
2234 as the reader and writer, allowing the user to register dialects
2235 without first creating a dialect class.
2236 + a configurable limit to the size of parsed fields has been added -
2237 previously, an unmatched quote character could result in the entire
2238 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002239 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002240 the parser field size limit (returning the former limit). The initial
2241 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002242 + A line_num attribute has been added to the reader object, which tracks
2243 the number of lines read from the source iterator. This is not
2244 the same as the number of records returned, as records can span
2245 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002246 + reader and writer objects were not being registered with the cyclic-GC.
2247 This has been fixed.
2248
Brett Cannone6539c42005-01-08 02:43:53 +00002249- _DummyThread objects in the threading module now delete self.__block that is
2250 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2251 lock primitives tend to be limited in number and thus should not be wasted on
2252 a _DummyThread object. Fixes bug #1089632.
2253
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002254- The imghdr module now detects Exif files.
2255
Raymond Hettinger6065d322004-12-20 23:51:53 +00002256- StringIO.truncate() now correctly adjusts the size attribute.
2257 (Bug #951915).
2258
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002259- locale.py now uses an updated locale alias table (built using
2260 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2261 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002262 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002263
Raymond Hettinger3557f422004-12-07 12:02:02 +00002264- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2265
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002266- the pickle module no longer accepts the deprecated None option in the
2267 args tuple returned by __reduce__().
2268
Brett Cannon84667c02004-12-07 03:25:18 +00002269- optparse now optionally imports gettext. This allows its use in setup.py.
2270
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002271- the pickle module no longer uses the deprecated bin parameter.
2272
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002273- the shelve module no longer uses the deprecated binary parameter.
2274
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002275- the pstats module no longer uses the deprecated ignore() method.
2276
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002277- the filecmp module no longer uses the deprecated use_statcache argument.
2278
Raymond Hettinger664347b2004-12-04 21:21:53 +00002279- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2280 extended or overridden by subclasses. Formerly, the subclassed method would
2281 be ignored by the rest of the module. (Bug #1078905).
2282
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002283- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002284 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002285
Walter Dörwald36733692004-12-22 12:50:50 +00002286- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2287 once when a size argument is given. This prevents a buffer overflow in the
2288 tokenizer with very long source lines.
2289
Barry Warsaw538561e2006-01-01 21:48:54 +00002290- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2291 immediately after creating the object, without any intervening
2292 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00002294- The reconvert.quote function can now emit triple-quoted strings. The
2295 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002296
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002297- ``UserString.MutableString`` now supports negative indices in
2298 ``__setitem__`` and ``__delitem__``
2299
Greg Ward40407942005-03-05 02:53:17 +00002300- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2301 correctly.
2302
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002303- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2304 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2305 character even if the user has passed a size parameter to get a proper
2306 line ending. Remove the special handling of a "\r\n" that has been split
2307 between two lines.
2308
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002309- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2310 about illegal code points. The codec now supports PEP 293 style error
2311 handlers.
2312
Walter Dörwald78a78b02005-09-01 12:04:29 +00002313- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002314 from the input stream, so that the output is a byte string in the correct
2315 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002316
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002317- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2318 considering it exactly like a '*'.
2319
Walter Dörwald007f8df2005-10-09 19:42:27 +00002320- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2321 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002322
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002323- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2324
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002325- Patch #1413711: Certain patterns of differences were making difflib
2326 touch the recursion limit.
2327
Walter Dörwald58917a62006-03-31 15:26:22 +00002328- Bug #947906: An object oriented interface has been added to the calendar
2329 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002330 called as a script (e.g. via ``python -mcalendar``). Localized month and
2331 weekday names can be ouput (even if an exotic encoding is used) using
2332 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002334Build
2335-----
2336
Neal Norwitz602d3392006-03-31 08:21:40 +00002337- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2338 by using -mieee gcc option.
2339
Martin v. Löwis86d66262006-02-17 08:40:11 +00002340- Patch #1432345: Make python compile on DragonFly.
2341
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002342- Build support for Win64-AMD64 was added.
2343
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002344- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2345
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002346- Patch #881820: look for openpty and forkpty also in libbsd.
2347
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002348- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2349 The zlib module is now builtin on Windows.
2350
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002351- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2352
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002353- Bug #1189330: configure did not correctly determine the necessary
2354 value of LINKCC if python was built with GCC 4.0.
2355
Trent Mick8321b422005-07-26 02:29:21 +00002356- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2357 vulnerability in zlib 1.2.1 and 1.2.2.
2358
Brett Cannon08cd5982005-04-24 22:26:38 +00002359- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2360 flags that change binary compatibility. Changes were also made to
2361 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002362 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002363
Bob Ippolitoed233462005-03-29 13:47:59 +00002364- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2365 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2366 no longer exists). This configure patch makes things right.
2367
Martin v. Löwise2713be2005-03-08 15:03:08 +00002368- Bug #1158607: Build with --disable-unicode again.
2369
Brett Cannon46d96232005-02-16 00:07:19 +00002370- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2371 defined. Discovered as a result of not being able to build on OS X.
2372
Brett Cannon516592f2004-12-07 00:42:59 +00002373- setup.py now uses the directories specified in LDFLAGS using the -L option
2374 and in CPPFLAGS using the -I option for adding library and include
2375 directories, respectively, for compiling extension modules against. This has
2376 led to the core being compiled using the values in CPPFLAGS. It also removes
2377 the need for the special-casing of both DarwinPorts and Fink for darwin since
2378 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2379 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2380 Fink, ``-I/opt/local/include`` for DarwinPorts).
2381
Brett Cannon43802422005-02-10 20:48:03 +00002382- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2383 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2384 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2385 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002387C API
2388-----
2389
Tim Petersc9d78aa2006-03-26 23:27:58 +00002390- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2391 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2392 is obtained via the ``PyObject_`` family, it must be released via the
2393 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2394 always been officially true, but when Python's small-object allocator was
2395 introduced, an attempt was made to cater to a few extension modules
2396 discovered at the time that obtained memory via ``PyObject_New`` but
2397 released it via ``PyMem_DEL``. It's years later, and if such code still
2398 exists it will fail now (probably with segfaults, but calling wrong
2399 low-level memory management functions can yield many symptoms).
2400
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002401- Added a C API for set and frozenset objects.
2402
Raymond Hettinger66517482004-12-03 11:45:13 +00002403- Removed PyRange_New().
2404
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002405- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2406 mapping argument now. This string is used as a mapping table. Byte values
2407 greater than the length of the string and 0xFFFE are treated as undefined
2408 mappings.

2413
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002414- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002415
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002416- Patch #1276356: New resource "urlfetch" is implemented. This enables
2417 even impatient people to run tests that require remote files.
