Georg Brandlba83f822010-03-14 09:50:54 +000028 for ``TimedRotatingFileHandler`` by using the modification time of an
29 existing log file to compute the next rollover time. If the log file does
30 not exist, the current time is used as the basis for the computation.

41 a base64 transfer-encoded payload *after* decoding it; it no longer does.
42 This is a behavior change, so email's minor version number is now bumped, to
43 version 4.0.2, for the 2.7 release.

Georg Brandlba83f822010-03-14 09:50:54 +000050- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
51 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
52 argument's __int__ method to convert to an integer before packing. It also
53 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
54 was inconsistent: __int__ was used for some integer codes but not for others,
55 and the set of integer codes for which it was used differed between native
56 packing and standard packing.)

398Core and Builtins
399-----------------
400
Georg Brandlba83f822010-03-14 09:50:54 +0000401- The ``__complex__()`` method is now looked up on the class of instances to
402 make it consistent with other special methods.

406
Mark Dickinson1b34d252010-01-01 17:27:30 +0000407- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000408 DeprecationWarning when passed a float argument where an integer was expected.
409 These functions and methods now raise TypeError instead. The majority of the
410 effects of this change are in the extension modules, but some core functions
411 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
412 and many unicode/str methods.

424
Georg Brandlba83f822010-03-14 09:50:54 +0000425- Issue #1811: Improve accuracy and cross-platform consistency for true division
426 of integers: the result of a/b is now correctly rounded for ints a and b (at
427 least on IEEE 754 platforms), and in particular does not depend on the
428 internal representation of a long.

436
Georg Brandlba83f822010-03-14 09:50:54 +0000437 These executables now work properly with the arch(1) command: ``arch -ppc
438 python`` will start a universal binary version of python in PPC mode (unlike
439 previous releases).

579 to 'g' for large values.

Georg Brandlba83f822010-03-14 09:50:54 +0000595- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
596 decimal string that's guaranteed to round back to x under correct rounding
597 (with round-half-to-even rounding mode). Previously it gave a string based on
598 rounding x to 17 decimal digits. repr(x) for a complex number behaves
599 similarly. On platforms where the correctly-rounded strtod and dtoa code is
600 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000601
Georg Brandlba83f822010-03-14 09:50:54 +0000602- Issue #7117: On almost all platforms: float-to-string and string-to-float
603 conversions within Python are now correctly rounded. Places these conversions
604 occur include: str for floats and complex numbers; the float and complex
605 constructors; old-style and new-style numeric formatting; serialization and
606 deserialization of floats and complex numbers using marshal, pickle and json;
607 parsing of float and imaginary literals in Python code; Decimal-to-float
608 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000609
Georg Brandlba83f822010-03-14 09:50:54 +0000610 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
611 providing correctly-rounded strtod and dtoa C functions. This code is
612 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
613 the C compiler. There may be a small number of platforms on which correct
614 operation of this code cannot be guaranteed, so the code is not used: notably,
615 this applies to platforms where the C double format is not IEEE 754 binary64,
616 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
617 and Python's configure script is unable to determine how to change the FPU
618 precision. On these platforms conversions use the platform strtod and dtoa,
619 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000621- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
622 uses the correctly-rounded string <-> float conversions described above (when
623 available), and so produces correctly rounded results that will display nicely
624 under the float repr. There are two related small changes: (1) round now
625 accepts any class with an ``__index__()`` method for its second argument (but
626 no longer accepts floats for the second argument), and (2) an excessively
627 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
628 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000775- Issue #5920: For ``float.__format__()``, change the behavior with the empty
776 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
777 but with at least one decimal point and with a default precision
778 of 12. Previously, the behavior the same but with a default precision of 6.
779 This more closely matches ``str()``, and reduces surprises when adding
780 alignment flags to the empty presentation type. This also affects the new
781 complex.__format__ in the same way.

1034 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1035 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1036 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00001038- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001041- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1043 gives improved memory leak detection when running under Valgrind, while taking
1044 advantage of pymalloc at other times.

2211 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2212 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002409- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2410
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002411- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2412 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2413 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2414 ``printf`` function, whereas PyString_FromFormat has an independent
2415 implementation and uses "%zd" on all platforms for size_t values.
2416 This makes a difference on win64, where ``printf`` needs "%Id" to display
2417 64bit values.
2418
Benjamin Peterson97179b02008-09-09 20:55:01 +00002419- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2420 error.
2421
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002422- Issue #3777: long() applied to a float object now always return a long
2423 object; previously an int would be returned for small values. the __long__
2424 method is allowed to return either an int or a long, but the behaviour of
2425 float objects should not change to respect backward compatibility.
2426
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002427- Issue #3751: str.rpartition would perform a left-partition when called with
2428 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002433 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002434 was correctly parsed but parsing of subsequent arguments failed.
2435
Vinay Sajip35e3b032008-09-01 14:33:59 +00002436- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002437 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2438 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2439 when given a tuple of classes as second argument, were looking up
2440 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2441 type object.
2442
Neal Norwitz18aa3882008-08-24 05:04:52 +00002443- Fix crashes on memory allocation failure found with failmalloc.

2512 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2513 for catch_warnings() also led to an improvement in the raising of a
2514 DeprecationWarning related to warnings.warn_explicit().

2586-----------------
2587
Guido van Rossumf8402962008-08-20 15:01:50 +00002588- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2589 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2590 extensions do not automatically benefit from the class attribute
2591 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2592 to their tp_flags field if they care. This is a backwards
2593 compatibility feature; in 3.0, all types will use the cache by
2594 default.
2595
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002596- Keyword arguments can now follow starred arguments. (``f(a, *args,
2597 keyword=23)`` is now valid syntax.)
2598
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002599- ctypes function pointers that are COM methods have a boolean True
2600 value again.
2601
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002602- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2603 by denying s# to parse objects that have a releasebuffer procedure,
2604 and introducing s*.
2605
Georg Brandl1e13ea92008-08-11 09:07:59 +00002606- Issue #3537: Fix an assertion failure when an empty but presized dict
2607 object was stored in the freelist.
2608
Mark Dickinsonb6467572008-08-04 21:30:09 +00002609- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2610 ValueError consistently across platforms.
2611
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002612- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2613 (64bit Unix, for example), unichr() would truncate its argument and return
2614 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2615
Neal Norwitze7d8be82008-07-31 17:17:14 +00002616- Apply security patches from Apple.
2617
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002618- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2619 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2620
Antoine Pitrou92f82162008-07-25 22:22:08 +00002621- Issue #1819: function calls with several named parameters are now on
2622 average 35% faster (as measured by pybench).
2623
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002624- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2625 the python debugger steps into a class statement: the free variables (local
2626 variables defined in an outer scope) would be deleted from the outer scope.
2627
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002628- Issue #2620: Overflow checking when allocating or reallocating memory
2629 was not always being done properly in some python types and extension
2630 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2631 all been updated to perform better checks and places in the code that
2632 would previously leak memory on the error path when such an allocation
2633 failed have been fixed.

2639
Benjamin Petersone977ad42008-08-20 01:42:01 +00002640- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2641 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2642
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002643- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2644 version reported by these tools does not necessarily follow the python
2645 version numbering scheme, so the module is less strict when parsing it.
2646
Nick Coghlanf70385a2008-08-18 12:42:46 +00002647- Issue #2235: Added Py3k warnings for types which will become unhashable
2648 under the stricter __hash__ inheritance rules in 3.0. Several types
2649 which did not meet the rules for hash invariants and were already
2650 unhashable in 3.0 have now been explicitly flagged as unhashable in
2651 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2652 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2653
Brett Cannon88f801d2008-08-18 00:46:22 +00002654- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2683 thread-safe.
2684
Brett Cannonbf3157b2008-08-14 05:00:03 +00002685- Silence the DeprecationWarning of rfc822 when it is imported by mimetools

2687 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2688

2701 to _sre.compile() will now be rejected. This should not affect anybody
2702 since the re.compile() function never generates invalid re-bytecode.

2706 it wasn't initialized during instantiation.
2707
Brett Cannon3aa2a492008-08-06 22:28:09 +00002708- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2709 the reload() built-in has been removed.

2720 raised an AttributeError.
2721
Benjamin Peterson01a24322008-07-28 23:35:27 +00002722- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002723 asking for a specific length. This problem only affected files opened
2724 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002725

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002749- Issue #3394: zipfile.writestr sets external attributes when passed a
2750 file name rather than a ZipInfo instance, so files are extracted with
2751 mode 0600 rather than 000 under Unix.
2752
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002753- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2766 interaction with the tp_hash slot (added in 2.6b2) are now documented
2767
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002768- Issue #643841: The language reference now provides more detailed

2775================================
2776
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002777*Release date: 17-Jul-2008*
2778
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002779Core and Builtins
2780-----------------
2781
Georg Brandl3e483f62008-07-16 22:57:41 +00002782- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2783 its methods now allow for items objects that can be converted to
2784 an integer using operator.index().
2785
Mark Dickinson64b7e502008-07-16 09:40:03 +00002786- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2787 produced a ValueError instead of giving the correct float.
2788
Eric Smitha5fa5a22008-07-16 00:11:49 +00002789- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2790 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2791
Mark Dickinson7103aa42008-07-15 19:08:33 +00002792- Issue #3008: the float type has a new instance method 'float.hex'
2793 and a new class method 'float.fromhex' to convert floating-point
2794 numbers to and from hexadecimal strings, respectively.
2795
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002796- Issue #2235: __hash__ is once again inherited by default. To allow
2797 collections.Hashable to remain meaningful in the presence of the
2798 default hash implementation (object.__hash__), it is now possible
2799 to explicit block inheritance of hash by setting __hash__=None at
2800 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2801 level.
2802
Nick Coghlanb028f502008-07-13 14:52:36 +00002803- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2804 the parent module cannot be found while performing an absolute import.
2805 This means that an incorrectly defined __package__ attribute will
2806 now only prevent relative imports in that module rather than causing
2807 all imports from that module to fail.
2808
Nick Coghlan14ff9942008-07-08 14:21:42 +00002809- Issue #2517: Allow unicode messages in Exceptions again by correctly
2810 bypassing the instance dictionary when looking up __unicode__ on
2811 new-style classes.
2812
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002813- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2814 set to a custom object whose write() method happens to install
2815 another file in sys.stdout.
2816
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002817- Issue #3088: Corrected a race condition in classes derived from
2818 threading.local: the first member set by a thread could be saved in
2819 another thread's dictionary.
2820
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002821- Issue #3004: Minor change to slice.indices(): the start and stop
2822 arguments are now treated identically, making the behaviour easier
2823 to describe and understand. For example, slice(None, -10,
2824 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2825 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2826 10, -1).
2827
Georg Brandl278fc502008-07-19 12:46:12 +00002828- Issue #3219: Calling a function with repeated keyword arguments,
2829 f(a=2, a=23), would not cause a syntax error. This was a regression
2830 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002831
Georg Brandl278fc502008-07-19 12:46:12 +00002832- Issue #2862: Make int and float freelist management consistent with
2833 other freelists. Changes their CompactFreeList apis into
2834 ClearFreeList apis and calls them via gc.collect().

2837-------
2838
Thomas Heller57adf222008-08-14 19:10:48 +00002839- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2840 api functions without holding the GIL, which could lead to a fatal
2841 error when they failed.
2842
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002843- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2853
Vinay Sajip51e65192008-07-18 09:01:10 +00002854- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002866- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002867
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002868- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2869 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002870 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002871 content-length. The problem had been corrected in the 2.4 branch, but never
2872 merged into trunk.
2873

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002887- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2888 handling is now the same as that of other special attributes like __name__).
2889
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002890- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003278- On MacOS X it is now possible to install the framework in 64-bit
3279 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003280 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003281
3282 This is controlled by the configure argument ``--with-universal-archs``:
3283
3284 - ``--with-universal-archs=all``: install 4-way universal
3285
3286 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3287
3288 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3289
3290 This option should be used in combination with ``--enable-universalsdk=``.
3291
3292 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Issue #1631171: Re-implement the 'warnings' module in C (the
3343 original Python code has been kept as backup). This will allow for
3344 using the 'warning's machinery in such places as the parser where
3345 use of pure Python code is not possible. Both the ``showarning()``
3346 and ``formatwarning()`` gain an optional 'line' argument which is
3347 not called by default for backwards-compatibility reasons. Setting
3348 ``warnings.showwarning()`` to an implementation that lacks support
3349 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Issue #2550: The approach used by client/server code for obtaining
3413 ports to listen on in network-oriented tests has been refined in an
3414 effort to facilitate running multiple instances of the entire
3415 regression test suite in parallel without issue.
3416 test_support.bind_port() has been fixed such that it will always
3417 return a unique port -- which wasn't always the case with the
3418 previous implementation, especially if socket options had been set
3419 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3420 new implementation of bind_port() will actually raise an exception
3421 if it is passed an AF_INET/SOCK_STREAM socket with either the
3422 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3423 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3424 the socket it's been passed. This currently only applies to
3425 Windows. This option prevents any other sockets from binding to the
3426 host/port we've bound to, thus removing the possibility of the
3427 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3428 when a second SOCK_STREAM socket binds and accepts to a host/port
3429 that's already been bound by another socket. The optional preferred
3430 port parameter to bind_port() has been removed. Under no
3431 circumstances should tests be hard coding ports!
3432
3433 test_support.find_unused_port() has also been introduced, which will
3434 pass a temporary socket object to bind_port() in order to obtain an
3435 unused port. The temporary socket object is then closed and
3436 deleted, and the port is returned. This method should only be used
3437 for obtaining an unused port in order to pass to an external program
3438 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3439 a parameter to a server-oriented class that doesn't give you direct
3440 access to the underlying socket used.
3441
3442 Finally, test_support.HOST has been introduced, which should be used
3443 for the host argument of any relevant socket calls (i.e. bind and
3444 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003445
3446 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003447 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003448 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3449 test_asynchat and test_socket_ssl.
3450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451 It is now possible for multiple instances of the regression test
3452 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003506- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3508 Plane. This affected raw unicode literals and the
3509 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3510 this case, like normal unicode literals and the 'unicode-escape'
3511 codec.

3734 differ slightly in their output formats from the existing, unchanged

3736 module is:
3737 from future_builtins import hex, oct

3740 exponents for exponents with absolute value < 100. Follows C99
3741 standard. This is a change on Windows, which would use 3 digits.
3742 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3743 so that any alterations it does to the resulting string will be
3744 available in stringlib/formatter.h (for float.__format__).
3745
Eric Smith5a3c1352008-02-19 13:21:56 +00003746- Implemented PEP 3101, Advanced String Formatting. This adds a new
3747 builtin format(); a format() method for str and unicode; a
3748 __format__() method to object, str, unicode, int, long, float, and
3749 datetime; the class string.Formatter; and the C API
3750 PyObject_Format().
3751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Fixed several potential crashes, all caused by specially crafted
3753 __del__ methods exploiting objects in temporarily inconsistent
3754 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Clear all free lists during a gc.collect() of the highest generation
3764 in order to allow pymalloc to free more arenas. Python may give back
3765 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Issue #2045: Fix an infinite recursion triggered when printing a
3768 subclass of collections.defaultdict, if its default_factory is set
3769 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Patch #1473257: generator objects gain a gi_code attribute. This is
3798 the same object as the func_code attribute of the function that
3799 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Issue #1920: "while 0" statements were completely removed by the
3802 compiler, even in the presence of an "else" clause, which is
3803 supposed to be run when the condition is false. Now the compiler
3804 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003805
Guido van Rossumeead05f2008-01-24 18:21:02 +00003806- A few crashers fixed: weakref_in_del.py (issue #1377858);
3807 loosing_dict_ref.py (issue #1303614, test67.py);
3808 borrowed_ref_[34].py (not in tracker).
3809
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003810- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003811 suppressed while an extension is loaded by calling SetErrorMode in

3813
Georg Brandl3ee81df2008-05-17 18:14:43 +00003814- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003815 several extension methods and modules do not work without unicode
3816 support.
3817
Georg Brandl26543b12008-01-21 18:36:51 +00003818- Issue #1882: when compiling code from a string, encoding cookies in the

3822
Georg Brandl6caad7d2008-01-26 14:19:22 +00003823- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003824 added.
3825
Christian Heimesc94e2b52008-01-14 04:13:37 +00003826- sys.float_info / PyFloat_GetInfo: The floating point information
3827 object was converted from a dict to a specialized structseq object.
3828
Georg Brandl3ee81df2008-05-17 18:14:43 +00003829- Patch #1816: Added sys.flags structseq. It exposes the status of
3830 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Objects/structseq.c: Implemented new structseq representation. The
3833 patch makes structseqs (e.g. the return value of os.stat) more
3834 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003835
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836- Patch #1700288: added a type attribute cache that caches method
3837 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003838

3845 envvar and sys.dont_write_bytecode attribute. All these can be set
3846 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Improve some exception messages when Windows fails to load an
3849 extension module. Now we get for example '%1 is not a valid Win32
3850 application' instead of 'error code 193'.

3907
Georg Brandl21e99f42010-03-07 15:23:59 +00003908- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3910 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Issue #1686386: Tuple's tp_repr did not take into account the
3913 possibility of having a self-referential tuple, which is possible
3914 from C code. Nor did object's tp_str consider that a type's tp_str
3915 could do something that could lead to an inifinite recursion.
3916 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3917 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003918
Georg Brandl3ee81df2008-05-17 18:14:43 +00003919- Issue #1164: It was possible to trigger deadlock when using the
3920 'print' statement to write to a file since the GIL was not released
3921 as needed. Now PyObject_Print() does the right thing along with
3922 various tp_print implementations of the built-in types and those in
3923 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003933 PyObject_Call() never calling back out to Python code to trigger
3934 recursion depth updates/checks. Required the creation of a static
3935 RuntimeError instance in case normalizing an exception put the
3936 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00003980- Patch #1682205: a TypeError while unpacking an iterable is no longer
3981 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00003985- Bug #1683368: The object.__init__() and object.__new__() methods are
3986 now stricter in rejecting excess arguments. The only time when
3987 either allows excess arguments is when it is not overridden and the
3988 other one is. For backwards compatibility, when both are
3989 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003990 warning later). Also, type.__init__() insists on the same signature
3991 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003993- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3994 object to complex using its __complex__() method before falling back
3995 to the __float__() method. Therefore, the functions in the cmath
3996 module now can operate on objects that define a __complex__()
3997 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004015- Bug #1678647: write a newline after printing an exception in any
4016 case, even when converting the value to a string failed.
4017
Georg Brandl871f1bc2007-03-12 13:17:36 +00004018- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019 its argument, if it exists. If not, it will work like before. This
4020 allows customizing the output of dir() in the presence of a
4021 __getattr__().

4031 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004032
Georg Brandlaa2321b2007-03-07 00:40:28 +00004033- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004034 makes the filenames the warning module prints much more sensible
4035 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004048- Patch #1674228: when assigning a slice (old-style), check for the
4049 sq_ass_slice instead of the sq_slice slot.
4050
Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- When printing an unraisable error, don't print exceptions. before
4052 the name. This duplicates the behavior whening normally printing
4053 exceptions.

4062 created a weakref on itself during a __del__ call for new-style
4063 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004103- Bug #1545497: when given an explicit base, int() did ignore NULs
4104 embedded in the string to convert.
4105
Georg Brandl846f73a2006-10-08 07:11:54 +00004106- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004154 generator expressions (x for x, in ... ) works again. Fixing this
4155 problem required changing the .pyc magic number. This means that
4156 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- The implementation of UnicodeError objects has been simplified
4960 (start and end attributes are now stored directly as Py_ssize_t
4961 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4964 with RFC 3207 and forgets any knowledge obtained from the server not
4965 obtained from the TLS negotiation itself. Patch contributed by Bill
4966 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004967
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004969 that the SMTP.starttls() caller no longer needs to call ehlo()
4970 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971 does not claim to support starttls. Adds the
4972 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4973 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005015- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005016 works as expected. ``mmap.find`` also takes an optional ``end``
5017 parameter.

5042 contents before adding elements from the iterable. This fix brings
5043 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005044
Georg Brandl3ee81df2008-05-17 18:14:43 +00005045- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00005052- Marshal.dumps() now expects exact type matches for int, long, float,
5053 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5054 silently miscode subclasses of those types. Now, it raises a
5055 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005056

Georg Brandl3ee81df2008-05-17 18:14:43 +00005071 time so that opening a database previously created with the DB_DUP
5072 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5073 opens. Specifically: dictionary assignment to a DB object will
5074 replace all values for a given key when the database allows
5075 duplicate values. DB users should use DB.put(k, v) when they want
5076 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005077

5083 characters with ASCII value less than 32. Also, it correctly quotes
5084 dots only if they occur on a single line, as opposed to the previous
5085 behavior of quoting dots if they are the second character of any
5086 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005087

Georg Brandl3ee81df2008-05-17 18:14:43 +00005492- Removed the macfs module. It had been deprecated since Python 2.5.
5493 This lead to the deprecation of macostools.touched() as it relied
5494 solely on macfs and was a no-op under OS X.
