Vinay Sajipecfa08f2010-03-12 09:16:10 +000027- Issue #8117: logging: Improved algorithm for computing initial rollover time
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 +000052- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
53 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
54 argument's __int__ method to convert to an integer before packing. It also
55 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
56 was inconsistent: __int__ was used for some integer codes but not for others,
57 and the set of integer codes for which it was used differed between native
58 packing and standard packing.)

400Core and Builtins
401-----------------
402
Georg Brandlba83f822010-03-14 09:50:54 +0000403- The ``__complex__()`` method is now looked up on the class of instances to
404 make it consistent with other special methods.

408
Mark Dickinson1b34d252010-01-01 17:27:30 +0000409- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000410 DeprecationWarning when passed a float argument where an integer was expected.
411 These functions and methods now raise TypeError instead. The majority of the
412 effects of this change are in the extension modules, but some core functions
413 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
414 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000427- Issue #1811: Improve accuracy and cross-platform consistency for true division
428 of integers: the result of a/b is now correctly rounded for ints a and b (at
429 least on IEEE 754 platforms), and in particular does not depend on the
430 internal representation of a long.

438
Georg Brandlba83f822010-03-14 09:50:54 +0000439 These executables now work properly with the arch(1) command: ``arch -ppc
440 python`` will start a universal binary version of python in PPC mode (unlike
441 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000597- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
598 decimal string that's guaranteed to round back to x under correct rounding
599 (with round-half-to-even rounding mode). Previously it gave a string based on
600 rounding x to 17 decimal digits. repr(x) for a complex number behaves
601 similarly. On platforms where the correctly-rounded strtod and dtoa code is
602 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000603
Georg Brandlba83f822010-03-14 09:50:54 +0000604- Issue #7117: On almost all platforms: float-to-string and string-to-float
605 conversions within Python are now correctly rounded. Places these conversions
606 occur include: str for floats and complex numbers; the float and complex
607 constructors; old-style and new-style numeric formatting; serialization and
608 deserialization of floats and complex numbers using marshal, pickle and json;
609 parsing of float and imaginary literals in Python code; Decimal-to-float
610 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000611
Georg Brandlba83f822010-03-14 09:50:54 +0000612 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
613 providing correctly-rounded strtod and dtoa C functions. This code is
614 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
615 the C compiler. There may be a small number of platforms on which correct
616 operation of this code cannot be guaranteed, so the code is not used: notably,
617 this applies to platforms where the C double format is not IEEE 754 binary64,
618 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
619 and Python's configure script is unable to determine how to change the FPU
620 precision. On these platforms conversions use the platform strtod and dtoa,
621 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000623- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
624 uses the correctly-rounded string <-> float conversions described above (when
625 available), and so produces correctly rounded results that will display nicely
626 under the float repr. There are two related small changes: (1) round now
627 accepts any class with an ``__index__()`` method for its second argument (but
628 no longer accepts floats for the second argument), and (2) an excessively
629 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
630 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000772
Georg Brandlba83f822010-03-14 09:50:54 +0000773 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
774 (2) parsing of strings representing infinities and nans was locale aware; and
775 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +0000777- Issue #5920: For ``float.__format__()``, change the behavior with the empty
778 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
779 but with at least one decimal point and with a default precision
780 of 12. Previously, the behavior the same but with a default precision of 6.
781 This more closely matches ``str()``, and reduces surprises when adding
782 alignment flags to the empty presentation type. This also affects the new
783 complex.__format__ in the same way.
784
785- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

983 the file object behaves like a closed file. The ``FileIO`` object also got a

1036 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2213 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2214 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002411- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2412
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002413- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2414 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2415 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2416 ``printf`` function, whereas PyString_FromFormat has an independent
2417 implementation and uses "%zd" on all platforms for size_t values.
2418 This makes a difference on win64, where ``printf`` needs "%Id" to display
2419 64bit values.
2420
Benjamin Peterson97179b02008-09-09 20:55:01 +00002421- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2422 error.
2423
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002424- Issue #3777: long() applied to a float object now always return a long
2425 object; previously an int would be returned for small values. the __long__
2426 method is allowed to return either an int or a long, but the behaviour of
2427 float objects should not change to respect backward compatibility.
2428
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002429- Issue #3751: str.rpartition would perform a left-partition when called with
2430 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002435 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002436 was correctly parsed but parsing of subsequent arguments failed.
2437
Vinay Sajip35e3b032008-09-01 14:33:59 +00002438- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002439 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2440 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2441 when given a tuple of classes as second argument, were looking up
2442 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2443 type object.
2444
Neal Norwitz18aa3882008-08-24 05:04:52 +00002445- Fix crashes on memory allocation failure found with failmalloc.

2514 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2515 for catch_warnings() also led to an improvement in the raising of a

2588-----------------
2589
Guido van Rossumf8402962008-08-20 15:01:50 +00002590- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2591 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2592 extensions do not automatically benefit from the class attribute
2593 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2594 to their tp_flags field if they care. This is a backwards
2595 compatibility feature; in 3.0, all types will use the cache by
2596 default.
2597
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002598- Keyword arguments can now follow starred arguments. (``f(a, *args,
2599 keyword=23)`` is now valid syntax.)
2600
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002601- ctypes function pointers that are COM methods have a boolean True
2602 value again.
2603
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002604- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2605 by denying s# to parse objects that have a releasebuffer procedure,
2606 and introducing s*.
2607
Georg Brandl1e13ea92008-08-11 09:07:59 +00002608- Issue #3537: Fix an assertion failure when an empty but presized dict
2609 object was stored in the freelist.
2610
Mark Dickinsonb6467572008-08-04 21:30:09 +00002611- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2612 ValueError consistently across platforms.
2613
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002614- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2615 (64bit Unix, for example), unichr() would truncate its argument and return
2616 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2617
Neal Norwitze7d8be82008-07-31 17:17:14 +00002618- Apply security patches from Apple.
2619
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002620- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2621 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2622
Antoine Pitrou92f82162008-07-25 22:22:08 +00002623- Issue #1819: function calls with several named parameters are now on
2624 average 35% faster (as measured by pybench).
2625
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002626- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2627 the python debugger steps into a class statement: the free variables (local
2628 variables defined in an outer scope) would be deleted from the outer scope.
2629
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002630- Issue #2620: Overflow checking when allocating or reallocating memory
2631 was not always being done properly in some python types and extension
2632 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2633 all been updated to perform better checks and places in the code that
2634 would previously leak memory on the error path when such an allocation
2635 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002645- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2646 version reported by these tools does not necessarily follow the python
2647 version numbering scheme, so the module is less strict when parsing it.
2648
Nick Coghlanf70385a2008-08-18 12:42:46 +00002649- Issue #2235: Added Py3k warnings for types which will become unhashable
2650 under the stricter __hash__ inheritance rules in 3.0. Several types
2651 which did not meet the rules for hash invariants and were already
2652 unhashable in 3.0 have now been explicitly flagged as unhashable in
2653 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2654 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2655
Brett Cannon88f801d2008-08-18 00:46:22 +00002656- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2666 by using 's*' instead of 't#'.
2667
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002668- Issue #2222: Fixed reference leak when occurred os.rename()

2682 regular expression.
2683
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002684- Issue #3476: binary buffered reading through the new "io" library is now
2685 thread-safe.
2686
Brett Cannonbf3157b2008-08-14 05:00:03 +00002687- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2688 since mimetools itself is deprecated. Because modules are cached, all
2689 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2690
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002691- Issue #3134: shutil referenced undefined WindowsError symbol.

2697 version that did not raise a DeprecationWarning under -3.
2698

2703 to _sre.compile() will now be rejected. This should not affect anybody
2704 since the re.compile() function never generates invalid re-bytecode.
2705
Skip Montanaroa032bf42008-08-08 22:52:51 +00002706- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2707 upon first access it can be automatically initialized from the csv file if
2708 it wasn't initialized during instantiation.
2709
Brett Cannon3aa2a492008-08-06 22:28:09 +00002710- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2711 the reload() built-in has been removed.
2712
Brett Cannon7e30b672008-08-04 21:52:25 +00002713- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002714 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2722 raised an AttributeError.
2723
Benjamin Peterson01a24322008-07-28 23:35:27 +00002724- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002725 asking for a specific length. This problem only affected files opened
2726 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002727

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002751- Issue #3394: zipfile.writestr sets external attributes when passed a
2752 file name rather than a ZipInfo instance, so files are extracted with
2753 mode 0600 rather than 000 under Unix.
2754
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002755- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2756 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002767- Issue #2235: the C API function PyObject_HashNotImplemented and its
2768 interaction with the tp_hash slot (added in 2.6b2) are now documented
2769
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002770- Issue #643841: The language reference now provides more detailed
2771 coverage of the lookup process for special methods. The disclaimers
2772 regarding lack of coverage of new-style classes have also been
2773 removed, since the coverage is now fairly reasonable.

2777================================
2778
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002779*Release date: 17-Jul-2008*
2780
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002781Core and Builtins
2782-----------------
2783
Georg Brandl3e483f62008-07-16 22:57:41 +00002784- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2785 its methods now allow for items objects that can be converted to
2786 an integer using operator.index().
2787
Mark Dickinson64b7e502008-07-16 09:40:03 +00002788- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2789 produced a ValueError instead of giving the correct float.
2790
Eric Smitha5fa5a22008-07-16 00:11:49 +00002791- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2792 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2793
Mark Dickinson7103aa42008-07-15 19:08:33 +00002794- Issue #3008: the float type has a new instance method 'float.hex'
2795 and a new class method 'float.fromhex' to convert floating-point
2796 numbers to and from hexadecimal strings, respectively.
2797
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002798- Issue #2235: __hash__ is once again inherited by default. To allow
2799 collections.Hashable to remain meaningful in the presence of the
2800 default hash implementation (object.__hash__), it is now possible
2801 to explicit block inheritance of hash by setting __hash__=None at
2802 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2803 level.
2804
Nick Coghlanb028f502008-07-13 14:52:36 +00002805- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2806 the parent module cannot be found while performing an absolute import.
2807 This means that an incorrectly defined __package__ attribute will
2808 now only prevent relative imports in that module rather than causing
2809 all imports from that module to fail.
2810
Nick Coghlan14ff9942008-07-08 14:21:42 +00002811- Issue #2517: Allow unicode messages in Exceptions again by correctly
2812 bypassing the instance dictionary when looking up __unicode__ on
2813 new-style classes.
2814
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002815- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2816 set to a custom object whose write() method happens to install
2817 another file in sys.stdout.
2818
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002819- Issue #3088: Corrected a race condition in classes derived from
2820 threading.local: the first member set by a thread could be saved in
2821 another thread's dictionary.
2822
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002823- Issue #3004: Minor change to slice.indices(): the start and stop
2824 arguments are now treated identically, making the behaviour easier
2825 to describe and understand. For example, slice(None, -10,
2826 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2827 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2828 10, -1).
2829
Georg Brandl278fc502008-07-19 12:46:12 +00002830- Issue #3219: Calling a function with repeated keyword arguments,
2831 f(a=2, a=23), would not cause a syntax error. This was a regression
2832 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002833
Georg Brandl278fc502008-07-19 12:46:12 +00002834- Issue #2862: Make int and float freelist management consistent with
2835 other freelists. Changes their CompactFreeList apis into
2836 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002837

2839-------
2840
Thomas Heller57adf222008-08-14 19:10:48 +00002841- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2842 api functions without holding the GIL, which could lead to a fatal
2843 error when they failed.
2844
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002845- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2854 ForkingPickler.register() to resolve conflict with ctypes.
2855
Vinay Sajip51e65192008-07-18 09:01:10 +00002856- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002858- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2859 a valid dlerror() message.
2860
Thomas Heller2bad6572008-07-15 17:19:50 +00002861- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2862 incomplete structure was created.
2863

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002868- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002869
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002870- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2871 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002872 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002873 content-length. The problem had been corrected in the 2.4 branch, but never
2874 merged into trunk.
2875
Georg Brandle78fbcc2008-07-05 10:13:36 +00002876- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002889- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2890 handling is now the same as that of other special attributes like __name__).
2891
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002892- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003280- On MacOS X it is now possible to install the framework in 64-bit
3281 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003282 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003283
3284 This is controlled by the configure argument ``--with-universal-archs``:
3285
3286 - ``--with-universal-archs=all``: install 4-way universal
3287
3288 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3289
3290 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3291
3292 This option should be used in combination with ``--enable-universalsdk=``.
3293
3294 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 +00003344- Issue #1631171: Re-implement the 'warnings' module in C (the
3345 original Python code has been kept as backup). This will allow for
3346 using the 'warning's machinery in such places as the parser where
3347 use of pure Python code is not possible. Both the ``showarning()``
3348 and ``formatwarning()`` gain an optional 'line' argument which is
3349 not called by default for backwards-compatibility reasons. Setting
3350 ``warnings.showwarning()`` to an implementation that lacks support
3351 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003394 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Issue #2550: The approach used by client/server code for obtaining
3415 ports to listen on in network-oriented tests has been refined in an
3416 effort to facilitate running multiple instances of the entire
3417 regression test suite in parallel without issue.
3418 test_support.bind_port() has been fixed such that it will always
3419 return a unique port -- which wasn't always the case with the
3420 previous implementation, especially if socket options had been set
3421 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3422 new implementation of bind_port() will actually raise an exception
3423 if it is passed an AF_INET/SOCK_STREAM socket with either the
3424 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3425 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3426 the socket it's been passed. This currently only applies to
3427 Windows. This option prevents any other sockets from binding to the
3428 host/port we've bound to, thus removing the possibility of the
3429 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3430 when a second SOCK_STREAM socket binds and accepts to a host/port
3431 that's already been bound by another socket. The optional preferred
3432 port parameter to bind_port() has been removed. Under no
3433 circumstances should tests be hard coding ports!
3434
3435 test_support.find_unused_port() has also been introduced, which will
3436 pass a temporary socket object to bind_port() in order to obtain an
3437 unused port. The temporary socket object is then closed and
3438 deleted, and the port is returned. This method should only be used
3439 for obtaining an unused port in order to pass to an external program
3440 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3441 a parameter to a server-oriented class that doesn't give you direct
3442 access to the underlying socket used.
3443
3444 Finally, test_support.HOST has been introduced, which should be used
3445 for the host argument of any relevant socket calls (i.e. bind and
3446 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003447
3448 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003450 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3451 test_asynchat and test_socket_ssl.
3452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453 It is now possible for multiple instances of the regression test
3454 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003508- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3510 Plane. This affected raw unicode literals and the
3511 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3512 this case, like normal unicode literals and the 'unicode-escape'
3513 codec.

3732
Eric Smitha73fbe72008-02-23 03:09:44 +00003733- Added the future_builtins module, which contains hex() and oct().
3734 These are the PEP 3127 version of these functions, designed to be
3735 compatible with the hex() and oct() builtins from Python 3.0. They
3736 differ slightly in their output formats from the existing, unchanged
3737 Python 2.6 builtins. The expected usage of the future_builtins
3738 module is:

3740
Eric Smith7ef40bf2008-02-20 23:34:22 +00003741- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3742 exponents for exponents with absolute value < 100. Follows C99
3743 standard. This is a change on Windows, which would use 3 digits.
3744 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3745 so that any alterations it does to the resulting string will be
3746 available in stringlib/formatter.h (for float.__format__).
3747
Eric Smith5a3c1352008-02-19 13:21:56 +00003748- Implemented PEP 3101, Advanced String Formatting. This adds a new
3749 builtin format(); a format() method for str and unicode; a
3750 __format__() method to object, str, unicode, int, long, float, and
3751 datetime; the class string.Formatter; and the C API
3752 PyObject_Format().
3753
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754- Fixed several potential crashes, all caused by specially crafted
3755 __del__ methods exploiting objects in temporarily inconsistent
3756 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003757
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003758- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759 prevent a possible crash: an Abstract Base Class would try to access
3760 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003761

Georg Brandl3ee81df2008-05-17 18:14:43 +00003765- Clear all free lists during a gc.collect() of the highest generation
3766 in order to allow pymalloc to free more arenas. Python may give back
3767 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003768
Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Issue #2045: Fix an infinite recursion triggered when printing a
3770 subclass of collections.defaultdict, if its default_factory is set
3771 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- Patch #1473257: generator objects gain a gi_code attribute. This is
3800 the same object as the func_code attribute of the function that
3801 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003802
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803- Issue #1920: "while 0" statements were completely removed by the
3804 compiler, even in the presence of an "else" clause, which is
3805 supposed to be run when the condition is false. Now the compiler
3806 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003807
Guido van Rossumeead05f2008-01-24 18:21:02 +00003808- A few crashers fixed: weakref_in_del.py (issue #1377858);

3810 borrowed_ref_[34].py (not in tracker).
3811
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003812- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003813 suppressed while an extension is loaded by calling SetErrorMode in

3815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003817 several extension methods and modules do not work without unicode
3818 support.
3819
Georg Brandl26543b12008-01-21 18:36:51 +00003820- Issue #1882: when compiling code from a string, encoding cookies in the

3824
Georg Brandl6caad7d2008-01-26 14:19:22 +00003825- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003826 added.
3827
Christian Heimesc94e2b52008-01-14 04:13:37 +00003828- sys.float_info / PyFloat_GetInfo: The floating point information
3829 object was converted from a dict to a specialized structseq object.
3830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Patch #1816: Added sys.flags structseq. It exposes the status of
3832 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Objects/structseq.c: Implemented new structseq representation. The
3835 patch makes structseqs (e.g. the return value of os.stat) more
3836 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Patch #1700288: added a type attribute cache that caches method
3839 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003840
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003841- Bug #1776: __import__() no longer accepts filenames on any platform.

3847 envvar and sys.dont_write_bytecode attribute. All these can be set
3848 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Improve some exception messages when Windows fails to load an
3851 extension module. Now we get for example '%1 is not a valid Win32
3852 application' instead of 'error code 193'.

3909
Georg Brandl21e99f42010-03-07 15:23:59 +00003910- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003911 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3912 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003913
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Issue #1686386: Tuple's tp_repr did not take into account the
3915 possibility of having a self-referential tuple, which is possible
3916 from C code. Nor did object's tp_str consider that a type's tp_str
3917 could do something that could lead to an inifinite recursion.
3918 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3919 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003920
Georg Brandl3ee81df2008-05-17 18:14:43 +00003921- Issue #1164: It was possible to trigger deadlock when using the
3922 'print' statement to write to a file since the GIL was not released
3923 as needed. Now PyObject_Print() does the right thing along with
3924 various tp_print implementations of the built-in types and those in
3925 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003935 PyObject_Call() never calling back out to Python code to trigger
3936 recursion depth updates/checks. Required the creation of a static
3937 RuntimeError instance in case normalizing an exception put the
3938 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00003982- Patch #1682205: a TypeError while unpacking an iterable is no longer
3983 masked by a generic one with the message "unpack non-sequence".
3984
Neal Norwitzaa754b72007-03-21 06:39:48 +00003985- Remove unused file Python/fmod.c.
3986
Guido van Rossum143b5642007-03-23 04:58:42 +00003987- Bug #1683368: The object.__init__() and object.__new__() methods are
3988 now stricter in rejecting excess arguments. The only time when
3989 either allows excess arguments is when it is not overridden and the
3990 other one is. For backwards compatibility, when both are
3991 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003992 warning later). Also, type.__init__() insists on the same signature
3993 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003995- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3996 object to complex using its __complex__() method before falling back
3997 to the __float__() method. Therefore, the functions in the cmath
3998 module now can operate on objects that define a __complex__()
3999 method.

4016
Georg Brandl7b9c5552007-03-12 14:30:05 +00004017- Bug #1678647: write a newline after printing an exception in any
4018 case, even when converting the value to a string failed.
4019
Georg Brandl871f1bc2007-03-12 13:17:36 +00004020- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021 its argument, if it exists. If not, it will work like before. This
4022 allows customizing the output of dir() in the presence of a
4023 __getattr__().

4033 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004034
Georg Brandlaa2321b2007-03-07 00:40:28 +00004035- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036 makes the filenames the warning module prints much more sensible
4037 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004038

Georg Brandl0fca97a2007-03-05 22:28:08 +00004050- Patch #1674228: when assigning a slice (old-style), check for the
4051 sq_ass_slice instead of the sq_slice slot.
4052
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053- When printing an unraisable error, don't print exceptions. before
4054 the name. This duplicates the behavior whening normally printing
4055 exceptions.

4064 created a weakref on itself during a __del__ call for new-style
4065 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00004066
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00004067- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00004105- Bug #1545497: when given an explicit base, int() did ignore NULs
4106 embedded in the string to convert.
4107
Georg Brandl846f73a2006-10-08 07:11:54 +00004108- Bug #1569998: break inside a try statement (outside a loop) is now

Armin Rigo7ccbca92006-10-04 12:17:45 +00004113- A number of places, including integer negation and absolute value,
4114 were fixed to not rely on undefined behaviour of the C compiler
4115 anymore.

Georg Brandl4e933132006-09-06 20:05:58 +00004138- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
4139 Also make sure that every exception class has __module__ set to
4140 'exceptions'.

4154
Neal Norwitzdac090d2006-09-05 03:53:08 +00004155- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156 generator expressions (x for x, in ... ) works again. Fixing this
4157 problem required changing the .pyc magic number. This means that
4158 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00004159

Guido van Rossum8bc09652008-02-21 18:18:37 +00004197- Removed uses of dict.has_key() from distutils, and uses of
4198 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00004961- The implementation of UnicodeError objects has been simplified
4962 (start and end attributes are now stored directly as Py_ssize_t
4963 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004964
Georg Brandl3ee81df2008-05-17 18:14:43 +00004965- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4966 with RFC 3207 and forgets any knowledge obtained from the server not
4967 obtained from the TLS negotiation itself. Patch contributed by Bill
4968 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004971 that the SMTP.starttls() caller no longer needs to call ehlo()
4972 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973 does not claim to support starttls. Adds the
4974 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4975 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005017- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005018 works as expected. ``mmap.find`` also takes an optional ``end``
5019 parameter.

5044 contents before adding elements from the iterable. This fix brings
5045 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005046
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Added wide char functions to msvcrt module: getwch, getwche, putwch

5053
Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Marshal.dumps() now expects exact type matches for int, long, float,
5055 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5056 silently miscode subclasses of those types. Now, it raises a
5057 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005058

Georg Brandl3ee81df2008-05-17 18:14:43 +00005073 time so that opening a database previously created with the DB_DUP
5074 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5075 opens. Specifically: dictionary assignment to a DB object will
5076 replace all values for a given key when the database allows
5077 duplicate values. DB users should use DB.put(k, v) when they want
5078 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005079

5085 characters with ASCII value less than 32. Also, it correctly quotes
5086 dots only if they occur on a single line, as opposed to the previous
5087 behavior of quoting dots if they are the second character of any
5088 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005089

Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Removed the macfs module. It had been deprecated since Python 2.5.
5495 This lead to the deprecation of macostools.touched() as it relied
5496 solely on macfs and was a no-op under OS X.
