951
952- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
953 and later systems as is currently done for Python 3.x installers.
954 For 2.7.7 only, we will provide three installers:
955 the legacy deprecated 10.3+ 32-bit-only format;
956 the newer 10.5+ 32-bit-only format;
957 and the unchanged 10.6+ 64-/32-bit format.
958 Although binary installers will no longer be available from
959 python.org as of 2.7.8, it will still be possible to build from
960 source on 10.3.9 and 10.4 systems if necessary.

2343 32-bit-only installer Pythons on systems with Xcode 4 (currently
2344 OS X 10.8, 10.7, and optionally 10.6).
2345 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2346 * Since Xcode 4 removes ppc support, extension module builds now
2347 check for ppc compiler support and by default remove ppc and
2348 ppc64 archs when they are not available.
2349 * Extension module builds now revert to using system installed
2350 headers and libs (/usr and /System/Library) if the SDK used
2351 to build the interpreter is not installed or has moved.
2352 * Try to avoid building extension modules with deprecated
2353 and problematic Apple llvm-gcc compiler. If original compiler
2354 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002718- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2719 int.__pow__. These overflow checks were causing int.__pow__ to produce
2720 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002721 compiler optimizing the check away. Also fix similar overflow checks
2722 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2723 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002791- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002792 has left two versions of customize_compiler, the original in
2793 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002798- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2799 Distutils-based packages with C extension modules may fail because
2800 Apple has removed gcc-4.2, the version used to build python.org
2801 64-bit/32-bit Pythons. If the user does not explicitly override
2802 the default C compiler by setting the CC environment variable,
2803 Distutils will now attempt to compile extension modules with clang
2804 if gcc-4.2 is required but not found. Also as a convenience, if
2805 the user does explicitly set CC, substitute its value as the default
2806 compiler in the Distutils LDSHARED configuration variable for OS X.
2807 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2808 SDK, neither of which are available in Xcode 4. This change does not
2809 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003059- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3060 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3061 interpreter process. This could cause failures in non-Distutils subprocesses
3062 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003063 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003064 deployment target only in the environment of each build subprocess. It is
3065 still possible to globally override the default by setting
3066 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3067 greater or equal to the default value, the value with which the interpreter
3068 was built.

3098 the ticker doesn't have to wind down to zero from the old starting point
3099 before the new interval takes effect. And if the user increases the
3100 interval, it makes sure the new limit takes effect right away rather have an
3101 early task switch before recognizing the new interval.

4099 This prevents user-created self-referencing ordered dictionaries from
4100 becoming permanently uncollectable GC garbage. The downside is that
4101 removing __del__ means that the internal doubly-linked list has to wait for
4102 GC collection rather than freeing memory immediately when the refcnt drops
4103 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004561- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4562 start byte and the continuation byte(s) are now considered invalid, instead
4563 of the number of bytes specified by the start byte.
4564 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4565 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4566 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004575- Issue #8748: Fix two issues with comparisons between complex and integer
4576 objects. (1) The comparison could incorrectly return True in some cases
4577 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4578 (2) The comparison raised an OverflowError for large integers, leading
4579 to unpredictable exceptions when combining integers and complex objects
4580 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00004719- Issue #1533: Fix inconsistency in range function argument processing: any
4720 non-float non-integer argument is now converted to an integer (if possible)
4721 using its __int__ method. Previously, only small arguments were treated this
4722 way; larger arguments (those whose __int__ was outside the range of a C long)
4723 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004773- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4774 operation raises multiple signals and more than one of those signals is
4775 trapped, the specification determines the order in which the signals should be
4776 handled. In many cases this order wasn't being followed, leading to the wrong
4777 Python exception being raised.

4963 with a non-empty format string. This is an effort to future-proof user
4964 code. If a derived class does not currently implement __format__ but later
4965 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004966 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004967 Python 3.3 and it will be an error in Python 3.4.

5556Core and Builtins
5557-----------------
5558
Georg Brandlba83f822010-03-14 09:50:54 +00005559- The ``__complex__()`` method is now looked up on the class of instances to
5560 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005562- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5563 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5564
Mark Dickinson1b34d252010-01-01 17:27:30 +00005565- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005566 DeprecationWarning when passed a float argument where an integer was expected.
5567 These functions and methods now raise TypeError instead. The majority of the
5568 effects of this change are in the extension modules, but some core functions
5569 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5570 and many unicode/str methods.

5581 used to drop the time part of the result.
5582
Georg Brandlba83f822010-03-14 09:50:54 +00005583- Issue #1811: Improve accuracy and cross-platform consistency for true division
5584 of integers: the result of a/b is now correctly rounded for ints a and b (at
5585 least on IEEE 754 platforms), and in particular does not depend on the
5586 internal representation of a long.

5594
Georg Brandlba83f822010-03-14 09:50:54 +00005595 These executables now work properly with the arch(1) command: ``arch -ppc
5596 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005752- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5753 decimal string that's guaranteed to round back to x under correct rounding
5754 (with round-half-to-even rounding mode). Previously it gave a string based on
5755 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5756 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5757 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005758
Georg Brandlba83f822010-03-14 09:50:54 +00005759- Issue #7117: On almost all platforms: float-to-string and string-to-float
5760 conversions within Python are now correctly rounded. Places these conversions
5761 occur include: str for floats and complex numbers; the float and complex
5762 constructors; old-style and new-style numeric formatting; serialization and
5763 deserialization of floats and complex numbers using marshal, pickle and json;
5764 parsing of float and imaginary literals in Python code; Decimal-to-float
5765 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005766
Georg Brandlba83f822010-03-14 09:50:54 +00005767 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5768 providing correctly-rounded strtod and dtoa C functions. This code is
5769 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5770 the C compiler. There may be a small number of platforms on which correct
5771 operation of this code cannot be guaranteed, so the code is not used: notably,
5772 this applies to platforms where the C double format is not IEEE 754 binary64,
5773 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5774 and Python's configure script is unable to determine how to change the FPU
5775 precision. On these platforms conversions use the platform strtod and dtoa,
5776 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005778- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5779 uses the correctly-rounded string <-> float conversions described above (when
5780 available), and so produces correctly rounded results that will display nicely
5781 under the float repr. There are two related small changes: (1) round now
5782 accepts any class with an ``__index__()`` method for its second argument (but
5783 no longer accepts floats for the second argument), and (2) an excessively
5784 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5785 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005927
Georg Brandlba83f822010-03-14 09:50:54 +00005928 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5929 (2) parsing of strings representing infinities and nans was locale aware; and
5930 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005932- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5933 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5934 but with at least one decimal point and with a default precision
5935 of 12. Previously, the behavior the same but with a default precision of 6.
5936 This more closely matches ``str()``, and reduces surprises when adding
5937 alignment flags to the empty presentation type. This also affects the new
5938 complex.__format__ in the same way.
5939
5940- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5941 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00006003 untrackable objects are not tracked by the garbage collector. This can reduce

6012 internal representation of integers, for performance reasons. Base 2**30 is
6013 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00006121- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6122 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6123 instances. On a typical machine this saves 3 bytes of memory (on average) per
6124 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006126- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6128 instead of throwing a MemoryError.
6129
Georg Brandlba83f822010-03-14 09:50:54 +00006130- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00006133- Issue #4367: Python would segfault during compiling when the unicodedata

6135
Georg Brandlba83f822010-03-14 09:50:54 +00006136- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6137 file objects with closefd=False. The file descriptor is still kept open but
6138 the file object behaves like a closed file. The ``FileIO`` object also got a
6139 new readonly attribute ``closefd``.

6158
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006159- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006162- On windows, ``os.chdir()`` given unicode was not working if
6163 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6164 this code path is really executed because I cannot move to such directory on
6165 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00006166
Georg Brandlba83f822010-03-14 09:50:54 +00006167- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6168 element is temporarily replaced with an equivalent frozenset. But the
6169 eventual KeyError would always report the empty ``frozenset()`` as the missing
6170 key. Now it correctly refers to the initial element.

6188 returned them on 64bit platforms.
6189
Walter Dörwalded960ac2009-05-03 22:36:33 +00006190- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6191 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6192 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6193 of using the replace error handler in PyUnicode_DecodeUTF8().
6194
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006195- Issue #3739: The unicode-internal encoder now reports the number of characters
6196 consumed like any other encoder (instead of the number of bytes).
6197
Georg Brandlba83f822010-03-14 09:50:54 +00006198- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6199 allocator will be automatically disabled when running under Valgrind. This
6200 gives improved memory leak detection when running under Valgrind, while taking
6201 advantage of pymalloc at other times.

7488 should cause a test to be skipped are now done using import_module from test
7489 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007592- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7593 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7594 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7595 ``printf`` function, whereas PyString_FromFormat has an independent
7596 implementation and uses "%zd" on all platforms for size_t values.
7597 This makes a difference on win64, where ``printf`` needs "%Id" to display
7598 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007617- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007618 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7619 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7620 when given a tuple of classes as second argument, were looking up
7621 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7622 type object.

7767-----------------
7768
Guido van Rossumf8402962008-08-20 15:01:50 +00007769- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7770 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7771 extensions do not automatically benefit from the class attribute
7772 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7773 to their tp_flags field if they care. This is a backwards
7774 compatibility feature; in 3.0, all types will use the cache by
7775 default.
7776
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007777- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00007790- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7791 ValueError consistently across platforms.
7792
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007793- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7794 (64bit Unix, for example), unichr() would truncate its argument and return
7795 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7796
Neal Norwitze7d8be82008-07-31 17:17:14 +00007797- Apply security patches from Apple.

7800 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7801
Antoine Pitrou92f82162008-07-25 22:22:08 +00007802- Issue #1819: function calls with several named parameters are now on
7803 average 35% faster (as measured by pybench).

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007805- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7806 the python debugger steps into a class statement: the free variables (local
7807 variables defined in an outer scope) would be deleted from the outer scope.
7808
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007809- Issue #2620: Overflow checking when allocating or reallocating memory
7810 was not always being done properly in some python types and extension
7811 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7812 all been updated to perform better checks and places in the code that
7813 would previously leak memory on the error path when such an allocation
7814 failed have been fixed.

7823
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007824- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7825 version reported by these tools does not necessarily follow the python
7826 version numbering scheme, so the module is less strict when parsing it.
7827
Nick Coghlanf70385a2008-08-18 12:42:46 +00007828- Issue #2235: Added Py3k warnings for types which will become unhashable
7829 under the stricter __hash__ inheritance rules in 3.0. Several types
7830 which did not meet the rules for hash invariants and were already
7831 unhashable in 3.0 have now been explicitly flagged as unhashable in
7832 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00007866- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7867 since mimetools itself is deprecated. Because modules are cached, all
7868 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7869

7882 to _sre.compile() will now be rejected. This should not affect anybody
7883 since the re.compile() function never generates invalid re-bytecode.
7884
Skip Montanaroa032bf42008-08-08 22:52:51 +00007885- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

7887 it wasn't initialized during instantiation.
7888
Brett Cannon3aa2a492008-08-06 22:28:09 +00007889- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7890 the reload() built-in has been removed.
7891
Brett Cannon7e30b672008-08-04 21:52:25 +00007892- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007904 asking for a specific length. This problem only affected files opened
7905 using the new "io" module, not the built-in open() function.

7931 file name rather than a ZipInfo instance, so files are extracted with
7932 mode 0600 rather than 000 under Unix.
7933
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007934- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7935 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007946- Issue #2235: the C API function PyObject_HashNotImplemented and its
7947 interaction with the tp_hash slot (added in 2.6b2) are now documented
7948
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007949- Issue #643841: The language reference now provides more detailed
7950 coverage of the lookup process for special methods. The disclaimers
7951 regarding lack of coverage of new-style classes have also been
7952 removed, since the coverage is now fairly reasonable.

7956================================
7957
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007958*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007960Core and Builtins
7961-----------------
7962
Georg Brandl3e483f62008-07-16 22:57:41 +00007963- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7964 its methods now allow for items objects that can be converted to
7965 an integer using operator.index().
7966
Mark Dickinson64b7e502008-07-16 09:40:03 +00007967- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7968 produced a ValueError instead of giving the correct float.
7969
Eric Smitha5fa5a22008-07-16 00:11:49 +00007970- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7971 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7972
Mark Dickinson7103aa42008-07-15 19:08:33 +00007973- Issue #3008: the float type has a new instance method 'float.hex'
7974 and a new class method 'float.fromhex' to convert floating-point
7975 numbers to and from hexadecimal strings, respectively.
7976
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007977- Issue #2235: __hash__ is once again inherited by default. To allow
7978 collections.Hashable to remain meaningful in the presence of the
7979 default hash implementation (object.__hash__), it is now possible
7980 to explicit block inheritance of hash by setting __hash__=None at
7981 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7982 level.
7983
Nick Coghlanb028f502008-07-13 14:52:36 +00007984- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7985 the parent module cannot be found while performing an absolute import.
7986 This means that an incorrectly defined __package__ attribute will
7987 now only prevent relative imports in that module rather than causing
7988 all imports from that module to fail.
7989
Nick Coghlan14ff9942008-07-08 14:21:42 +00007990- Issue #2517: Allow unicode messages in Exceptions again by correctly
7991 bypassing the instance dictionary when looking up __unicode__ on
7992 new-style classes.
7993
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007994- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7995 set to a custom object whose write() method happens to install
7996 another file in sys.stdout.
7997
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007998- Issue #3088: Corrected a race condition in classes derived from
7999 threading.local: the first member set by a thread could be saved in
8000 another thread's dictionary.
8001
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008002- Issue #3004: Minor change to slice.indices(): the start and stop
8003 arguments are now treated identically, making the behaviour easier
8004 to describe and understand. For example, slice(None, -10,
8005 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8006 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8007 10, -1).
8008
Georg Brandl278fc502008-07-19 12:46:12 +00008009- Issue #3219: Calling a function with repeated keyword arguments,
8010 f(a=2, a=23), would not cause a syntax error. This was a regression
8011 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008012
Georg Brandl278fc502008-07-19 12:46:12 +00008013- Issue #2862: Make int and float freelist management consistent with
8014 other freelists. Changes their CompactFreeList apis into
8015 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008016

8019
Thomas Heller57adf222008-08-14 19:10:48 +00008020- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8021 api functions without holding the GIL, which could lead to a fatal
8022 error when they failed.
8023
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008024- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8033 ForkingPickler.register() to resolve conflict with ctypes.
8034
Vinay Sajip51e65192008-07-18 09:01:10 +00008035- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008036
Thomas Heller880f5292008-07-15 19:39:38 +00008037- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8038 a valid dlerror() message.
8039
Thomas Heller2bad6572008-07-15 17:19:50 +00008040- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8041 incomplete structure was created.
8042
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008043- Issue #3339: dummy_thread.acquire() should not return None.

8046
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008047- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008048
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008049- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8050 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008051 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008052 content-length. The problem had been corrected in the 2.4 branch, but never
8053 merged into trunk.
8054
Georg Brandle78fbcc2008-07-05 10:13:36 +00008055- Issue #2663: add filtering capability to shutil.copytree().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008459 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008460
8461 This is controlled by the configure argument ``--with-universal-archs``:
8462
8463 - ``--with-universal-archs=all``: install 4-way universal
8464
8465 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8466
8467 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8468
8469 This option should be used in combination with ``--enable-universalsdk=``.
8470
8471 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 +00008520- Issue #1631171: Re-implement the 'warnings' module in C (the
8521 original Python code has been kept as backup). This will allow for
8522 using the 'warning's machinery in such places as the parser where
8523 use of pure Python code is not possible. Both the ``showarning()``
8524 and ``formatwarning()`` gain an optional 'line' argument which is
8525 not called by default for backwards-compatibility reasons. Setting
8526 ``warnings.showwarning()`` to an implementation that lacks support
8527 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008590- Issue #2550: The approach used by client/server code for obtaining
8591 ports to listen on in network-oriented tests has been refined in an
8592 effort to facilitate running multiple instances of the entire
8593 regression test suite in parallel without issue.
8594 test_support.bind_port() has been fixed such that it will always
8595 return a unique port -- which wasn't always the case with the
8596 previous implementation, especially if socket options had been set
8597 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8598 new implementation of bind_port() will actually raise an exception
8599 if it is passed an AF_INET/SOCK_STREAM socket with either the
8600 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8601 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8602 the socket it's been passed. This currently only applies to
8603 Windows. This option prevents any other sockets from binding to the
8604 host/port we've bound to, thus removing the possibility of the
8605 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8606 when a second SOCK_STREAM socket binds and accepts to a host/port
8607 that's already been bound by another socket. The optional preferred
8608 port parameter to bind_port() has been removed. Under no
8609 circumstances should tests be hard coding ports!
8610
8611 test_support.find_unused_port() has also been introduced, which will
8612 pass a temporary socket object to bind_port() in order to obtain an
8613 unused port. The temporary socket object is then closed and
8614 deleted, and the port is returned. This method should only be used
8615 for obtaining an unused port in order to pass to an external program
8616 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8617 a parameter to a server-oriented class that doesn't give you direct
8618 access to the underlying socket used.
8619
8620 Finally, test_support.HOST has been introduced, which should be used
8621 for the host argument of any relevant socket calls (i.e. bind and
8622 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008623

8898
Fred Drakea8ee94b2008-03-01 02:45:07 +00008899- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008900 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008901
Georg Brandlad61bc82008-02-23 15:11:18 +00008902- Issue #2067: file.__exit__() now calls subclasses' close() method.
8903
8904- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008905
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008906- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008907 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008908
Eric Smitha73fbe72008-02-23 03:09:44 +00008909- Added the future_builtins module, which contains hex() and oct().
8910 These are the PEP 3127 version of these functions, designed to be
8911 compatible with the hex() and oct() builtins from Python 3.0. They
8912 differ slightly in their output formats from the existing, unchanged
8913 Python 2.6 builtins. The expected usage of the future_builtins
8914 module is:
8915 from future_builtins import hex, oct
8916
Eric Smith7ef40bf2008-02-20 23:34:22 +00008917- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8918 exponents for exponents with absolute value < 100. Follows C99
8919 standard. This is a change on Windows, which would use 3 digits.
8920 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8921 so that any alterations it does to the resulting string will be
8922 available in stringlib/formatter.h (for float.__format__).
8923
Eric Smith5a3c1352008-02-19 13:21:56 +00008924- Implemented PEP 3101, Advanced String Formatting. This adds a new
8925 builtin format(); a format() method for str and unicode; a
8926 __format__() method to object, str, unicode, int, long, float, and
8927 datetime; the class string.Formatter; and the C API
8928 PyObject_Format().
8929
Georg Brandl3ee81df2008-05-17 18:14:43 +00008930- Fixed several potential crashes, all caused by specially crafted
8931 __del__ methods exploiting objects in temporarily inconsistent
8932 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008933
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008934- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008935 prevent a possible crash: an Abstract Base Class would try to access
8936 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008937
Georg Brandl3ee81df2008-05-17 18:14:43 +00008938- Fixed repr() and str() of complex numbers with infinity or nan as
8939 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008940
Georg Brandl3ee81df2008-05-17 18:14:43 +00008941- Clear all free lists during a gc.collect() of the highest generation
8942 in order to allow pymalloc to free more arenas. Python may give back
8943 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008944
Georg Brandl3ee81df2008-05-17 18:14:43 +00008945- Issue #2045: Fix an infinite recursion triggered when printing a
8946 subclass of collections.defaultdict, if its default_factory is set
8947 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008948
Christian Heimesf75dbef2008-02-08 00:11:31 +00008949- Fixed a minor memory leak in dictobject.c. The content of the free
8950 list was not freed on interpreter shutdown.
8951
Georg Brandl21e99f42010-03-07 15:23:59 +00008952- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008953 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008954
Georg Brandl3ee81df2008-05-17 18:14:43 +00008955- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8956 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008957 to compact the internal free lists of pre-allocted ints and floats.
8958
Georg Brandl3ee81df2008-05-17 18:14:43 +00008959- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8960 calls. Python expected the return type int but the fork familie
8961 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008962
Georg Brandl3ee81df2008-05-17 18:14:43 +00008963- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8964 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008965
Georg Brandl3ee81df2008-05-17 18:14:43 +00008966- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8967 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008968
Georg Brandl3ee81df2008-05-17 18:14:43 +00008969- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8970 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008971
Georg Brandl3ee81df2008-05-17 18:14:43 +00008972- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8973 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008974
Georg Brandl3ee81df2008-05-17 18:14:43 +00008975- Patch #1473257: generator objects gain a gi_code attribute. This is
8976 the same object as the func_code attribute of the function that
8977 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008978
Georg Brandl3ee81df2008-05-17 18:14:43 +00008979- Issue #1920: "while 0" statements were completely removed by the
8980 compiler, even in the presence of an "else" clause, which is
8981 supposed to be run when the condition is false. Now the compiler
8982 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008983
Guido van Rossumeead05f2008-01-24 18:21:02 +00008984- A few crashers fixed: weakref_in_del.py (issue #1377858);
8985 loosing_dict_ref.py (issue #1303614, test67.py);
8986 borrowed_ref_[34].py (not in tracker).
8987
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008988- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008989 suppressed while an extension is loaded by calling SetErrorMode in
8990 dynload_win.c. The error is still reported properly.
8991
Georg Brandl3ee81df2008-05-17 18:14:43 +00008992- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008993 several extension methods and modules do not work without unicode
8994 support.
8995
Georg Brandl26543b12008-01-21 18:36:51 +00008996- Issue #1882: when compiling code from a string, encoding cookies in the
8997 second line of code were not always recognized correctly.
8998
Georg Brandl14404b62008-01-19 19:27:05 +00008999- Issue #1679: "0x" was taken as a valid integer literal.
9000
Georg Brandl6caad7d2008-01-26 14:19:22 +00009001- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009002 added.
9003
Christian Heimesc94e2b52008-01-14 04:13:37 +00009004- sys.float_info / PyFloat_GetInfo: The floating point information
9005 object was converted from a dict to a specialized structseq object.
9006
Georg Brandl3ee81df2008-05-17 18:14:43 +00009007- Patch #1816: Added sys.flags structseq. It exposes the status of
9008 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009009
Georg Brandl3ee81df2008-05-17 18:14:43 +00009010- Objects/structseq.c: Implemented new structseq representation. The
9011 patch makes structseqs (e.g. the return value of os.stat) more
9012 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009013
Georg Brandl3ee81df2008-05-17 18:14:43 +00009014- Patch #1700288: added a type attribute cache that caches method
9015 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009016
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009017- Bug #1776: __import__() no longer accepts filenames on any platform.
9018 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009019
Georg Brandlaed6c662008-01-07 17:25:53 +00009020- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9021
Georg Brandl3ee81df2008-05-17 18:14:43 +00009022- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9023 envvar and sys.dont_write_bytecode attribute. All these can be set
9024 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009025
Georg Brandl3ee81df2008-05-17 18:14:43 +00009026- Improve some exception messages when Windows fails to load an
9027 extension module. Now we get for example '%1 is not a valid Win32
9028 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009029
Georg Brandl3ee81df2008-05-17 18:14:43 +00009030- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009032- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9033 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009034
Christian Heimes0a8143f2007-12-18 23:22:54 +00009035- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009036 and INF. float("nan"), float("inf") and float("-inf") now work on
9037 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009038
Georg Brandl3ee81df2008-05-17 18:14:43 +00009039- Compiler now generates simpler and faster code for dictionary
9040 literals. The oparg for BUILD_MAP now indicates an estimated
9041 dictionary size. There is a new opcode, STORE_MAP, for adding
9042 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009043
Georg Brandl3ee81df2008-05-17 18:14:43 +00009044- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009049- Issue #1538: Avoid copying string in split/rsplit if the split char
9050 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009051
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009052- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009053 SystemError.
9054
Nick Coghlanef01d822007-12-03 12:55:17 +00009055- PEP 366: Allow explicit relative imports when executing modules
9056 inside packages with the -m switch via a new module level
9057 __package__ attribute.
9058
Georg Brandl3ee81df2008-05-17 18:14:43 +00009059- Issue #1402: Fix a crash on exit, when another thread is still
9060 running, and if the deallocation of its frames somehow calls the
9061 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009062

9072 file can now be directly executed by passing their name to the
9073 interpreter. The directory/zipfile is automatically inserted as the
9074 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009075
Georg Brandl3ee81df2008-05-17 18:14:43 +00009076- Issue #1265: Fix a problem with sys.settrace, if the tracing
9077 function uses a generator expression when at the same time the
9078 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009079
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009080- sets and frozensets now have an isdisjoint() method.
9081
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009082- optimize the performance of builtin.sum().
9083
Neal Norwitz44f326e2007-10-05 05:29:17 +00009084- Fix warnings found by the new version of the Coverity checker.
9085
Georg Brandl21e99f42010-03-07 15:23:59 +00009086- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009087 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9088 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009089
Georg Brandl3ee81df2008-05-17 18:14:43 +00009090- Issue #1686386: Tuple's tp_repr did not take into account the
9091 possibility of having a self-referential tuple, which is possible
9092 from C code. Nor did object's tp_str consider that a type's tp_str
9093 could do something that could lead to an inifinite recursion.
9094 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9095 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009096
Georg Brandl3ee81df2008-05-17 18:14:43 +00009097- Issue #1164: It was possible to trigger deadlock when using the
9098 'print' statement to write to a file since the GIL was not released
9099 as needed. Now PyObject_Print() does the right thing along with
9100 various tp_print implementations of the built-in types and those in
9101 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009102
Georg Brandl3ee81df2008-05-17 18:14:43 +00009103- Issue #1147: Exceptions were directly allowing string exceptions in
9104 their throw() method even though string exceptions no longer
9105 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009106
Georg Brandl3ee81df2008-05-17 18:14:43 +00009107- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00009110- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009111 PyObject_Call() never calling back out to Python code to trigger
9112 recursion depth updates/checks. Required the creation of a static
9113 RuntimeError instance in case normalizing an exception put the
9114 recursion check value past its limit. Fixes crashers
9115 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009116

Neal Norwitz0ac60192007-05-27 04:08:54 +00009130- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009131 __*__ attributes. (Some already existed, e.g., __doc__ and
9132 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009133
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009134- Add -3 option to the interpreter to warn about features that are

9139
Collin Winter62903052007-05-18 23:11:24 +00009140- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009141 "except E as target:". This is to provide forwards compatibility
9142 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009143
Brett Cannon229cee22007-05-05 01:34:02 +00009144- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009149- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009150 setting a plain string, ie don't expand to single letter identifiers.
9151
Raymond Hettinger13936692007-04-11 18:40:58 +00009152- Request #1191699: Slices can now be pickled.
9153

9162
Guido van Rossum143b5642007-03-23 04:58:42 +00009163- Bug #1683368: The object.__init__() and object.__new__() methods are
9164 now stricter in rejecting excess arguments. The only time when
9165 either allows excess arguments is when it is not overridden and the
9166 other one is. For backwards compatibility, when both are
9167 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009168 warning later). Also, type.__init__() insists on the same signature
9169 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009170
Georg Brandl3ee81df2008-05-17 18:14:43 +00009171- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9172 object to complex using its __complex__() method before falling back
9173 to the __float__() method. Therefore, the functions in the cmath
9174 module now can operate on objects that define a __complex__()
9175 method.

9179 same slot names.

9192
Georg Brandl7b9c5552007-03-12 14:30:05 +00009193- Bug #1678647: write a newline after printing an exception in any
9194 case, even when converting the value to a string failed.
9195
Georg Brandl871f1bc2007-03-12 13:17:36 +00009196- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009197 its argument, if it exists. If not, it will work like before. This
9198 allows customizing the output of dir() in the presence of a
9199 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009200
Collin Winter276887b2007-03-12 16:11:39 +00009201- Patch #922167: Python no longer segfaults when faced with infinitely

9208 parthensized forms. This means complex(repr(x)) now works instead of
9209 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009210
Georg Brandlaa2321b2007-03-07 00:40:28 +00009211- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009212 makes the filenames the warning module prints much more sensible
9213 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009214

Georg Brandl0fca97a2007-03-05 22:28:08 +00009226- Patch #1674228: when assigning a slice (old-style), check for the
9227 sq_ass_slice instead of the sq_slice slot.
9228
Georg Brandl3ee81df2008-05-17 18:14:43 +00009229- When printing an unraisable error, don't print exceptions. before

9853
Georg Brandl3ee81df2008-05-17 18:14:43 +00009854- unittest now verifies more of its assumptions. In particular,

9856 accepted in TestSuite.addTest(). This should cause no
9857 incompatibility since it never made sense with ordinary subclasses
9858 -- the failure just occurred later, with a more cumbersome
9859 exception.

10128 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010129
Georg Brandl3ee81df2008-05-17 18:14:43 +000010130- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010139- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010140 that the SMTP.starttls() caller no longer needs to call ehlo()
10141 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010142 does not claim to support starttls. Adds the
10143 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010186- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010187 works as expected. ``mmap.find`` also takes an optional ``end``

10224 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +000010242 time so that opening a database previously created with the DB_DUP
10243 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10244 opens. Specifically: dictionary assignment to a DB object will
10245 replace all values for a given key when the database allows
10246 duplicate values. DB users should use DB.put(k, v) when they want
10247 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010248

10254 characters with ASCII value less than 32. Also, it correctly quotes
10255 dots only if they occur on a single line, as opposed to the previous
10256 behavior of quoting dots if they are the second character of any
10257 line.

10585-----
10586
Georg Brandl3ee81df2008-05-17 18:14:43 +000010587- Unified naming convention for free lists and their limits. All free
10588 lists in Object/ are named ``free_list``, the counter ``numfree``
10589 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10590 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010591
Georg Brandl3ee81df2008-05-17 18:14:43 +000010592- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10593 to ``PyTuple_SetItem``, it can be used to populate a brand new
10594 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010595
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010596- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010598- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10599 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10600 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010601
10602- Patch #1720595: add T_BOOL to the range of structmember types.
10603
10604- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10605 ``PyFloat_GetInfo()`` to the float API.
10606
Georg Brandl3ee81df2008-05-17 18:14:43 +000010607- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10608 of w# format code incorrectly truncated the length to an int, even
10609 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10610 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010611
Georg Brandl3ee81df2008-05-17 18:14:43 +000010612- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10613 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010614
Georg Brandl3ee81df2008-05-17 18:14:43 +000010615- PEP 3123: Provide forward compatibility with Python 3.0, while
10616 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10617 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010618
Georg Brandl3ee81df2008-05-17 18:14:43 +000010619- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10620 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010621
10622- Patch #1733960: Allow T_LONGLONG to accept ints.
10623
10624- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10625

10629
10630- Fix some leftovers from the conversion from int to Py_ssize_t
10631 (relevant to strings and sequences of more than 2**31 items).
10632
10633- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10634 outside of pystate.c and should not be necessary.
10635
Georg Brandl3ee81df2008-05-17 18:14:43 +000010636- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10637 absolute imports. In earlier versions they might have used relative
10638 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010639
Georg Brandl3ee81df2008-05-17 18:14:43 +000010640- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10641 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010642
Georg Brandl3ee81df2008-05-17 18:14:43 +000010643- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10644 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010649- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10650 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10651 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10652 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010653
Georg Brandl3ee81df2008-05-17 18:14:43 +000010654- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +000010666- Removed the macfs module. It had been deprecated since Python 2.5.
10667 This lead to the deprecation of macostools.touched() as it relied
10668 solely on macfs and was a no-op under OS X.
