949
950- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
951 and later systems as is currently done for Python 3.x installers.
952 For 2.7.7 only, we will provide three installers:
953 the legacy deprecated 10.3+ 32-bit-only format;
954 the newer 10.5+ 32-bit-only format;
955 and the unchanged 10.6+ 64-/32-bit format.
956 Although binary installers will no longer be available from
957 python.org as of 2.7.8, it will still be possible to build from
958 source on 10.3.9 and 10.4 systems if necessary.

2341 32-bit-only installer Pythons on systems with Xcode 4 (currently
2342 OS X 10.8, 10.7, and optionally 10.6).
2343 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2344 * Since Xcode 4 removes ppc support, extension module builds now
2345 check for ppc compiler support and by default remove ppc and
2346 ppc64 archs when they are not available.
2347 * Extension module builds now revert to using system installed
2348 headers and libs (/usr and /System/Library) if the SDK used
2349 to build the interpreter is not installed or has moved.
2350 * Try to avoid building extension modules with deprecated
2351 and problematic Apple llvm-gcc compiler. If original compiler
2352 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002716- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2717 int.__pow__. These overflow checks were causing int.__pow__ to produce
2718 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002719 compiler optimizing the check away. Also fix similar overflow checks
2720 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2721 bugs caused test failures with recent versions of Clang.

2733 cleared by the garbage collector. This fixes a segfault when an instance
2734 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01002789- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002790 has left two versions of customize_compiler, the original in
2791 distutils.sysconfig and another copy in distutils.ccompiler, with some

2794 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002796- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2797 Distutils-based packages with C extension modules may fail because
2798 Apple has removed gcc-4.2, the version used to build python.org
2799 64-bit/32-bit Pythons. If the user does not explicitly override
2800 the default C compiler by setting the CC environment variable,
2801 Distutils will now attempt to compile extension modules with clang
2802 if gcc-4.2 is required but not found. Also as a convenience, if
2803 the user does explicitly set CC, substitute its value as the default
2804 compiler in the Distutils LDSHARED configuration variable for OS X.
2805 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2806 SDK, neither of which are available in Xcode 4. This change does not
2807 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003057- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3058 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3059 interpreter process. This could cause failures in non-Distutils subprocesses
3060 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003061 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003062 deployment target only in the environment of each build subprocess. It is
3063 still possible to globally override the default by setting
3064 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3065 greater or equal to the default value, the value with which the interpreter
3066 was built.

3095 updating the check interval, so if the user decreases the check interval,
3096 the ticker doesn't have to wind down to zero from the old starting point
3097 before the new interval takes effect. And if the user increases the
3098 interval, it makes sure the new limit takes effect right away rather have an
3099 early task switch before recognizing the new interval.

4097 This prevents user-created self-referencing ordered dictionaries from
4098 becoming permanently uncollectable GC garbage. The downside is that
4099 removing __del__ means that the internal doubly-linked list has to wait for
4100 GC collection rather than freeing memory immediately when the refcnt drops
4101 to zero.

4110 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004559- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4560 start byte and the continuation byte(s) are now considered invalid, instead
4561 of the number of bytes specified by the start byte.
4562 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4563 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4564 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4565 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004573- Issue #8748: Fix two issues with comparisons between complex and integer
4574 objects. (1) The comparison could incorrectly return True in some cases
4575 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4576 (2) The comparison raised an OverflowError for large integers, leading
4577 to unpredictable exceptions when combining integers and complex objects
4578 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004580- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004960- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4961 with a non-empty format string. This is an effort to future-proof user
4962 code. If a derived class does not currently implement __format__ but later
4963 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004964 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004965 Python 3.3 and it will be an error in Python 3.4.

Mark Dickinson8efef5c2010-01-12 22:23:56 +00005413
Georg Brandlba83f822010-03-14 09:50:54 +00005414 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
5415 strings,
5416 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5417 numeric strings corresponding to subnormal values,
5418 (3) a memory leak for some values large enough to cause overflow, and
5419 (4) a number of flaws that could lead to incorrectly rounded results.

5554Core and Builtins
5555-----------------
5556
Georg Brandlba83f822010-03-14 09:50:54 +00005557- The ``__complex__()`` method is now looked up on the class of instances to
5558 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005560- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5561 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5562
Mark Dickinson1b34d252010-01-01 17:27:30 +00005563- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005564 DeprecationWarning when passed a float argument where an integer was expected.
5565 These functions and methods now raise TypeError instead. The majority of the
5566 effects of this change are in the extension modules, but some core functions
5567 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5568 and many unicode/str methods.

5579 used to drop the time part of the result.
5580
Georg Brandlba83f822010-03-14 09:50:54 +00005581- Issue #1811: Improve accuracy and cross-platform consistency for true division
5582 of integers: the result of a/b is now correctly rounded for ints a and b (at
5583 least on IEEE 754 platforms), and in particular does not depend on the
5584 internal representation of a long.

5592
Georg Brandlba83f822010-03-14 09:50:54 +00005593 These executables now work properly with the arch(1) command: ``arch -ppc
5594 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005750- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5751 decimal string that's guaranteed to round back to x under correct rounding
5752 (with round-half-to-even rounding mode). Previously it gave a string based on
5753 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5754 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5755 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005756
Georg Brandlba83f822010-03-14 09:50:54 +00005757- Issue #7117: On almost all platforms: float-to-string and string-to-float
5758 conversions within Python are now correctly rounded. Places these conversions
5759 occur include: str for floats and complex numbers; the float and complex
5760 constructors; old-style and new-style numeric formatting; serialization and
5761 deserialization of floats and complex numbers using marshal, pickle and json;
5762 parsing of float and imaginary literals in Python code; Decimal-to-float
5763 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005764
Georg Brandlba83f822010-03-14 09:50:54 +00005765 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5766 providing correctly-rounded strtod and dtoa C functions. This code is
5767 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5768 the C compiler. There may be a small number of platforms on which correct
5769 operation of this code cannot be guaranteed, so the code is not used: notably,
5770 this applies to platforms where the C double format is not IEEE 754 binary64,
5771 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5772 and Python's configure script is unable to determine how to change the FPU
5773 precision. On these platforms conversions use the platform strtod and dtoa,
5774 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005776- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5777 uses the correctly-rounded string <-> float conversions described above (when
5778 available), and so produces correctly rounded results that will display nicely
5779 under the float repr. There are two related small changes: (1) round now
5780 accepts any class with an ``__index__()`` method for its second argument (but
5781 no longer accepts floats for the second argument), and (2) an excessively
5782 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5783 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005926 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5927 (2) parsing of strings representing infinities and nans was locale aware; and
5928 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005930- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5931 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5932 but with at least one decimal point and with a default precision
5933 of 12. Previously, the behavior the same but with a default precision of 6.
5934 This more closely matches ``str()``, and reduces surprises when adding
5935 alignment flags to the empty presentation type. This also affects the new
5936 complex.__format__ in the same way.
5937
5938- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00006119- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6120 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6121 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006124- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6133
Georg Brandlba83f822010-03-14 09:50:54 +00006134- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6135 file objects with closefd=False. The file descriptor is still kept open but
6136 the file object behaves like a closed file. The ``FileIO`` object also got a
6137 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00006160- On windows, ``os.chdir()`` given unicode was not working if

6162 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00006165- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6166 element is temporarily replaced with an equivalent frozenset. But the
6167 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00006188- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6189 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6190 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6191 of using the replace error handler in PyUnicode_DecodeUTF8().
6192
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006193- Issue #3739: The unicode-internal encoder now reports the number of characters

6195
Georg Brandlba83f822010-03-14 09:50:54 +00006196- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6198 gives improved memory leak detection when running under Valgrind, while taking
6199 advantage of pymalloc at other times.

7589
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007590- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7591 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7592 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7593 ``printf`` function, whereas PyString_FromFormat has an independent
7594 implementation and uses "%zd" on all platforms for size_t values.
7595 This makes a difference on win64, where ``printf`` needs "%Id" to display
7596 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007615- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007616 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7617 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7618 when given a tuple of classes as second argument, were looking up
7619 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7620 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00007767- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7768 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7769 extensions do not automatically benefit from the class attribute
7770 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7771 to their tp_flags field if they care. This is a backwards
7772 compatibility feature; in 3.0, all types will use the cache by
7773 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00007775- Keyword arguments can now follow starred arguments. (``f(a, *args,

7786 object was stored in the freelist.
7787
Mark Dickinsonb6467572008-08-04 21:30:09 +00007788- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7789 ValueError consistently across platforms.
7790
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007791- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7792 (64bit Unix, for example), unichr() would truncate its argument and return
7793 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007797- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7798 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7799
Antoine Pitrou92f82162008-07-25 22:22:08 +00007800- Issue #1819: function calls with several named parameters are now on
7801 average 35% faster (as measured by pybench).
7802
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007803- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7804 the python debugger steps into a class statement: the free variables (local
7805 variables defined in an outer scope) would be deleted from the outer scope.
7806
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007807- Issue #2620: Overflow checking when allocating or reallocating memory
7808 was not always being done properly in some python types and extension
7809 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7810 all been updated to perform better checks and places in the code that
7811 would previously leak memory on the error path when such an allocation
7812 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00007819- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7820 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7821
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007822- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7823 version reported by these tools does not necessarily follow the python
7824 version numbering scheme, so the module is less strict when parsing it.
7825
Nick Coghlanf70385a2008-08-18 12:42:46 +00007826- Issue #2235: Added Py3k warnings for types which will become unhashable
7827 under the stricter __hash__ inheritance rules in 3.0. Several types
7828 which did not meet the rules for hash invariants and were already
7829 unhashable in 3.0 have now been explicitly flagged as unhashable in
7830 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7831 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7832
Brett Cannon88f801d2008-08-18 00:46:22 +00007833- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00007864- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7865 since mimetools itself is deprecated. Because modules are cached, all
7866 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

7880 to _sre.compile() will now be rejected. This should not affect anybody
7881 since the re.compile() function never generates invalid re-bytecode.

7885 it wasn't initialized during instantiation.
7886
Brett Cannon3aa2a492008-08-06 22:28:09 +00007887- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7888 the reload() built-in has been removed.
7889
Brett Cannon7e30b672008-08-04 21:52:25 +00007890- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007902 asking for a specific length. This problem only affected files opened
7903 using the new "io" module, not the built-in open() function.

7929 file name rather than a ZipInfo instance, so files are extracted with
7930 mode 0600 rather than 000 under Unix.
7931
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007932- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

7945 interaction with the tp_hash slot (added in 2.6b2) are now documented
7946
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007947- Issue #643841: The language reference now provides more detailed
7948 coverage of the lookup process for special methods. The disclaimers
7949 regarding lack of coverage of new-style classes have also been
7950 removed, since the coverage is now fairly reasonable.

7954================================
7955
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007956*Release date: 17-Jul-2008*
7957
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007958Core and Builtins
7959-----------------
7960
Georg Brandl3e483f62008-07-16 22:57:41 +00007961- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7962 its methods now allow for items objects that can be converted to
7963 an integer using operator.index().
7964
Mark Dickinson64b7e502008-07-16 09:40:03 +00007965- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7966 produced a ValueError instead of giving the correct float.
7967
Eric Smitha5fa5a22008-07-16 00:11:49 +00007968- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7969 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7970
Mark Dickinson7103aa42008-07-15 19:08:33 +00007971- Issue #3008: the float type has a new instance method 'float.hex'
7972 and a new class method 'float.fromhex' to convert floating-point
7973 numbers to and from hexadecimal strings, respectively.
7974
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007975- Issue #2235: __hash__ is once again inherited by default. To allow
7976 collections.Hashable to remain meaningful in the presence of the
7977 default hash implementation (object.__hash__), it is now possible
7978 to explicit block inheritance of hash by setting __hash__=None at
7979 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7980 level.
7981
Nick Coghlanb028f502008-07-13 14:52:36 +00007982- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7983 the parent module cannot be found while performing an absolute import.
7984 This means that an incorrectly defined __package__ attribute will
7985 now only prevent relative imports in that module rather than causing
7986 all imports from that module to fail.
7987
Nick Coghlan14ff9942008-07-08 14:21:42 +00007988- Issue #2517: Allow unicode messages in Exceptions again by correctly
7989 bypassing the instance dictionary when looking up __unicode__ on
7990 new-style classes.
7991
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007992- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7993 set to a custom object whose write() method happens to install
7994 another file in sys.stdout.
7995
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007996- Issue #3088: Corrected a race condition in classes derived from
7997 threading.local: the first member set by a thread could be saved in
7998 another thread's dictionary.
7999
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008000- Issue #3004: Minor change to slice.indices(): the start and stop
8001 arguments are now treated identically, making the behaviour easier
8002 to describe and understand. For example, slice(None, -10,
8003 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8004 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8005 10, -1).
8006
Georg Brandl278fc502008-07-19 12:46:12 +00008007- Issue #3219: Calling a function with repeated keyword arguments,
8008 f(a=2, a=23), would not cause a syntax error. This was a regression
8009 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008010
Georg Brandl278fc502008-07-19 12:46:12 +00008011- Issue #2862: Make int and float freelist management consistent with
8012 other freelists. Changes their CompactFreeList apis into
8013 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008014

8017
Thomas Heller57adf222008-08-14 19:10:48 +00008018- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8019 api functions without holding the GIL, which could lead to a fatal
8020 error when they failed.
8021
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008022- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8031 ForkingPickler.register() to resolve conflict with ctypes.
8032
Vinay Sajip51e65192008-07-18 09:01:10 +00008033- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008034
Thomas Heller880f5292008-07-15 19:39:38 +00008035- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8036 a valid dlerror() message.
8037
Thomas Heller2bad6572008-07-15 17:19:50 +00008038- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8039 incomplete structure was created.
8040
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008041- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00008043- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
8044
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008045- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008046
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008047- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8048 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008049 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008050 content-length. The problem had been corrected in the 2.4 branch, but never
8051 merged into trunk.
8052
Georg Brandle78fbcc2008-07-05 10:13:36 +00008053- Issue #2663: add filtering capability to shutil.copytree().

8456 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008457 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008458
8459 This is controlled by the configure argument ``--with-universal-archs``:
8460
8461 - ``--with-universal-archs=all``: install 4-way universal
8462
8463 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8464
8465 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8466
8467 This option should be used in combination with ``--enable-universalsdk=``.
8468
8469 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 +00008518- Issue #1631171: Re-implement the 'warnings' module in C (the
8519 original Python code has been kept as backup). This will allow for
8520 using the 'warning's machinery in such places as the parser where
8521 use of pure Python code is not possible. Both the ``showarning()``
8522 and ``formatwarning()`` gain an optional 'line' argument which is
8523 not called by default for backwards-compatibility reasons. Setting
8524 ``warnings.showwarning()`` to an implementation that lacks support
8525 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008588- Issue #2550: The approach used by client/server code for obtaining
8589 ports to listen on in network-oriented tests has been refined in an
8590 effort to facilitate running multiple instances of the entire
8591 regression test suite in parallel without issue.
8592 test_support.bind_port() has been fixed such that it will always
8593 return a unique port -- which wasn't always the case with the
8594 previous implementation, especially if socket options had been set
8595 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8596 new implementation of bind_port() will actually raise an exception
8597 if it is passed an AF_INET/SOCK_STREAM socket with either the
8598 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8599 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8600 the socket it's been passed. This currently only applies to
8601 Windows. This option prevents any other sockets from binding to the
8602 host/port we've bound to, thus removing the possibility of the
8603 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8604 when a second SOCK_STREAM socket binds and accepts to a host/port
8605 that's already been bound by another socket. The optional preferred
8606 port parameter to bind_port() has been removed. Under no
8607 circumstances should tests be hard coding ports!
8608
8609 test_support.find_unused_port() has also been introduced, which will
8610 pass a temporary socket object to bind_port() in order to obtain an
8611 unused port. The temporary socket object is then closed and
8612 deleted, and the port is returned. This method should only be used
8613 for obtaining an unused port in order to pass to an external program
8614 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8615 a parameter to a server-oriented class that doesn't give you direct
8616 access to the underlying socket used.
8617
8618 Finally, test_support.HOST has been introduced, which should be used
8619 for the host argument of any relevant socket calls (i.e. bind and
8620 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008621
8622 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008623 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008624 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8625 test_asynchat and test_socket_ssl.

8895-----------------
8896
Fred Drakea8ee94b2008-03-01 02:45:07 +00008897- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008898 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008899
Georg Brandlad61bc82008-02-23 15:11:18 +00008900- Issue #2067: file.__exit__() now calls subclasses' close() method.
8901
8902- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008903
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008904- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008905 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008906
Eric Smitha73fbe72008-02-23 03:09:44 +00008907- Added the future_builtins module, which contains hex() and oct().
8908 These are the PEP 3127 version of these functions, designed to be
8909 compatible with the hex() and oct() builtins from Python 3.0. They
8910 differ slightly in their output formats from the existing, unchanged
8911 Python 2.6 builtins. The expected usage of the future_builtins
8912 module is:
8913 from future_builtins import hex, oct
8914
Eric Smith7ef40bf2008-02-20 23:34:22 +00008915- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8916 exponents for exponents with absolute value < 100. Follows C99
8917 standard. This is a change on Windows, which would use 3 digits.
8918 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8919 so that any alterations it does to the resulting string will be
8920 available in stringlib/formatter.h (for float.__format__).
8921
Eric Smith5a3c1352008-02-19 13:21:56 +00008922- Implemented PEP 3101, Advanced String Formatting. This adds a new
8923 builtin format(); a format() method for str and unicode; a
8924 __format__() method to object, str, unicode, int, long, float, and
8925 datetime; the class string.Formatter; and the C API
8926 PyObject_Format().
8927
Georg Brandl3ee81df2008-05-17 18:14:43 +00008928- Fixed several potential crashes, all caused by specially crafted
8929 __del__ methods exploiting objects in temporarily inconsistent
8930 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008931
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008932- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008933 prevent a possible crash: an Abstract Base Class would try to access
8934 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008935
Georg Brandl3ee81df2008-05-17 18:14:43 +00008936- Fixed repr() and str() of complex numbers with infinity or nan as
8937 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008938
Georg Brandl3ee81df2008-05-17 18:14:43 +00008939- Clear all free lists during a gc.collect() of the highest generation
8940 in order to allow pymalloc to free more arenas. Python may give back
8941 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008942
Georg Brandl3ee81df2008-05-17 18:14:43 +00008943- Issue #2045: Fix an infinite recursion triggered when printing a
8944 subclass of collections.defaultdict, if its default_factory is set
8945 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008946
Christian Heimesf75dbef2008-02-08 00:11:31 +00008947- Fixed a minor memory leak in dictobject.c. The content of the free
8948 list was not freed on interpreter shutdown.
8949
Georg Brandl21e99f42010-03-07 15:23:59 +00008950- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008951 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008952
Georg Brandl3ee81df2008-05-17 18:14:43 +00008953- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8954 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008955 to compact the internal free lists of pre-allocted ints and floats.
8956
Georg Brandl3ee81df2008-05-17 18:14:43 +00008957- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8958 calls. Python expected the return type int but the fork familie
8959 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008960
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8962 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008963
Georg Brandl3ee81df2008-05-17 18:14:43 +00008964- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8965 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008966
Georg Brandl3ee81df2008-05-17 18:14:43 +00008967- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8968 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008969
Georg Brandl3ee81df2008-05-17 18:14:43 +00008970- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8971 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008972
Georg Brandl3ee81df2008-05-17 18:14:43 +00008973- Patch #1473257: generator objects gain a gi_code attribute. This is
8974 the same object as the func_code attribute of the function that
8975 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008976
Georg Brandl3ee81df2008-05-17 18:14:43 +00008977- Issue #1920: "while 0" statements were completely removed by the
8978 compiler, even in the presence of an "else" clause, which is
8979 supposed to be run when the condition is false. Now the compiler
8980 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008981
Guido van Rossumeead05f2008-01-24 18:21:02 +00008982- A few crashers fixed: weakref_in_del.py (issue #1377858);
8983 loosing_dict_ref.py (issue #1303614, test67.py);
8984 borrowed_ref_[34].py (not in tracker).
8985
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008986- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008987 suppressed while an extension is loaded by calling SetErrorMode in
8988 dynload_win.c. The error is still reported properly.
8989
Georg Brandl3ee81df2008-05-17 18:14:43 +00008990- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008991 several extension methods and modules do not work without unicode
8992 support.
8993
Georg Brandl26543b12008-01-21 18:36:51 +00008994- Issue #1882: when compiling code from a string, encoding cookies in the
8995 second line of code were not always recognized correctly.
8996
Georg Brandl14404b62008-01-19 19:27:05 +00008997- Issue #1679: "0x" was taken as a valid integer literal.
8998
Georg Brandl6caad7d2008-01-26 14:19:22 +00008999- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009000 added.
9001
Christian Heimesc94e2b52008-01-14 04:13:37 +00009002- sys.float_info / PyFloat_GetInfo: The floating point information
9003 object was converted from a dict to a specialized structseq object.
9004
Georg Brandl3ee81df2008-05-17 18:14:43 +00009005- Patch #1816: Added sys.flags structseq. It exposes the status of
9006 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009007
Georg Brandl3ee81df2008-05-17 18:14:43 +00009008- Objects/structseq.c: Implemented new structseq representation. The
9009 patch makes structseqs (e.g. the return value of os.stat) more
9010 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009011
Georg Brandl3ee81df2008-05-17 18:14:43 +00009012- Patch #1700288: added a type attribute cache that caches method
9013 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009014
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009015- Bug #1776: __import__() no longer accepts filenames on any platform.
9016 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009017
Georg Brandlaed6c662008-01-07 17:25:53 +00009018- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9019
Georg Brandl3ee81df2008-05-17 18:14:43 +00009020- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9021 envvar and sys.dont_write_bytecode attribute. All these can be set
9022 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009023
Georg Brandl3ee81df2008-05-17 18:14:43 +00009024- Improve some exception messages when Windows fails to load an
9025 extension module. Now we get for example '%1 is not a valid Win32
9026 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009027
Georg Brandl3ee81df2008-05-17 18:14:43 +00009028- Bug #1481296: Fixed long(float('nan')) != 0L.

9031 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009032
Christian Heimes0a8143f2007-12-18 23:22:54 +00009033- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009034 and INF. float("nan"), float("inf") and float("-inf") now work on
9035 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009036
Georg Brandl3ee81df2008-05-17 18:14:43 +00009037- Compiler now generates simpler and faster code for dictionary
9038 literals. The oparg for BUILD_MAP now indicates an estimated
9039 dictionary size. There is a new opcode, STORE_MAP, for adding
9040 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009041
Georg Brandl3ee81df2008-05-17 18:14:43 +00009042- Issue #1638: %zd configure test fails on Linux.

9055 __package__ attribute.
9056
Georg Brandl3ee81df2008-05-17 18:14:43 +00009057- Issue #1402: Fix a crash on exit, when another thread is still
9058 running, and if the deallocation of its frames somehow calls the
9059 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009060

Georg Brandl3ee81df2008-05-17 18:14:43 +00009074- Issue #1265: Fix a problem with sys.settrace, if the tracing
9075 function uses a generator expression when at the same time the
9076 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009077
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009078- sets and frozensets now have an isdisjoint() method.
9079
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009080- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00009082- Fix warnings found by the new version of the Coverity checker.
9083
Georg Brandl21e99f42010-03-07 15:23:59 +00009084- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009085 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9086 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009087
Georg Brandl3ee81df2008-05-17 18:14:43 +00009088- Issue #1686386: Tuple's tp_repr did not take into account the
9089 possibility of having a self-referential tuple, which is possible
9090 from C code. Nor did object's tp_str consider that a type's tp_str
9091 could do something that could lead to an inifinite recursion.
9092 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9093 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Issue #1164: It was possible to trigger deadlock when using the
9096 'print' statement to write to a file since the GIL was not released
9097 as needed. Now PyObject_Print() does the right thing along with
9098 various tp_print implementations of the built-in types and those in
9099 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009100
Georg Brandl3ee81df2008-05-17 18:14:43 +00009101- Issue #1147: Exceptions were directly allowing string exceptions in
9102 their throw() method even though string exceptions no longer
9103 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009104

Brett Cannon1e534b52007-09-07 04:18:30 +00009108- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009109 PyObject_Call() never calling back out to Python code to trigger
9110 recursion depth updates/checks. Required the creation of a static
9111 RuntimeError instance in case normalizing an exception put the
9112 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00009128- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009129 __*__ attributes. (Some already existed, e.g., __doc__ and
9130 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009131
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009132- Add -3 option to the interpreter to warn about features that are

9136 calls.
9137
Collin Winter62903052007-05-18 23:11:24 +00009138- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009139 "except E as target:". This is to provide forwards compatibility
9140 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009141
Brett Cannon229cee22007-05-05 01:34:02 +00009142- Deprecate BaseException.message as per PEP 352.
9143
Georg Brandl3ee81df2008-05-17 18:14:43 +00009144- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009145 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009146
Vinay Sajip8549ce32007-05-06 17:53:37 +00009147- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009148 setting a plain string, ie don't expand to single letter identifiers.
9149
Raymond Hettinger13936692007-04-11 18:40:58 +00009150- Request #1191699: Slices can now be pickled.
9151
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009152- Request #1193128: str.translate() now allows a None argument for

9154 remaining characters.
9155
Georg Brandl5cb76c12007-03-21 09:00:39 +00009156- Patch #1682205: a TypeError while unpacking an iterable is no longer

9160
Guido van Rossum143b5642007-03-23 04:58:42 +00009161- Bug #1683368: The object.__init__() and object.__new__() methods are
9162 now stricter in rejecting excess arguments. The only time when
9163 either allows excess arguments is when it is not overridden and the
9164 other one is. For backwards compatibility, when both are
9165 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009166 warning later). Also, type.__init__() insists on the same signature
9167 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9170 object to complex using its __complex__() method before falling back
9171 to the __float__() method. Therefore, the functions in the cmath
9172 module now can operate on objects that define a __complex__()
9173 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009174
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175- Patch #1623563: allow __class__ assignment for classes with
9176 __slots__. The old and the new class are still required to have the
9177 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009178

9190
Georg Brandl7b9c5552007-03-12 14:30:05 +00009191- Bug #1678647: write a newline after printing an exception in any
9192 case, even when converting the value to a string failed.
9193
Georg Brandl871f1bc2007-03-12 13:17:36 +00009194- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009195 its argument, if it exists. If not, it will work like before. This
9196 allows customizing the output of dir() in the presence of a
9197 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009198
Collin Winter276887b2007-03-12 16:11:39 +00009199- Patch #922167: Python no longer segfaults when faced with infinitely
9200 self-recursive reload() calls (as reported by bug #742342).

9206 parthensized forms. This means complex(repr(x)) now works instead of
9207 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009208
Georg Brandlaa2321b2007-03-07 00:40:28 +00009209- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009210 makes the filenames the warning module prints much more sensible
9211 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009212
Georg Brandl49aafc92007-03-07 00:34:46 +00009213- Variant of patch #697613: don't exit the interpreter on a SystemExit
9214 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009215 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00009224- Patch #1674228: when assigning a slice (old-style), check for the
9225 sq_ass_slice instead of the sq_slice slot.
9226
Georg Brandl3ee81df2008-05-17 18:14:43 +00009227- When printing an unraisable error, don't print exceptions. before
9228 the name. This duplicates the behavior whening normally printing
9229 exceptions.

9238 created a weakref on itself during a __del__ call for new-style
9239 classes (classic classes still have the bug).

9851
Georg Brandl3ee81df2008-05-17 18:14:43 +00009852- unittest now verifies more of its assumptions. In particular,

9854 accepted in TestSuite.addTest(). This should cause no
9855 incompatibility since it never made sense with ordinary subclasses
9856 -- the failure just occurred later, with a more cumbersome
9857 exception.

10126 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010127
Georg Brandl3ee81df2008-05-17 18:14:43 +000010128- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010137- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010138 that the SMTP.starttls() caller no longer needs to call ehlo()
10139 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010140 does not claim to support starttls. Adds the
10141 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010184- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010185 works as expected. ``mmap.find`` also takes an optional ``end``

10222 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +000010240 time so that opening a database previously created with the DB_DUP
10241 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10242 opens. Specifically: dictionary assignment to a DB object will
10243 replace all values for a given key when the database allows
10244 duplicate values. DB users should use DB.put(k, v) when they want
10245 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010246

10252 characters with ASCII value less than 32. Also, it correctly quotes
10253 dots only if they occur on a single line, as opposed to the previous
10254 behavior of quoting dots if they are the second character of any
10255 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010256

10583-----
10584
Georg Brandl3ee81df2008-05-17 18:14:43 +000010585- Unified naming convention for free lists and their limits. All free
10586 lists in Object/ are named ``free_list``, the counter ``numfree``
10587 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10588 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010589
Georg Brandl3ee81df2008-05-17 18:14:43 +000010590- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10591 to ``PyTuple_SetItem``, it can be used to populate a brand new
10592 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010593
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010594- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010596- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10597 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10598 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010599
10600- Patch #1720595: add T_BOOL to the range of structmember types.
10601
10602- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10603 ``PyFloat_GetInfo()`` to the float API.
10604
Georg Brandl3ee81df2008-05-17 18:14:43 +000010605- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10606 of w# format code incorrectly truncated the length to an int, even
10607 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10608 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010609
Georg Brandl3ee81df2008-05-17 18:14:43 +000010610- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10611 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010612
Georg Brandl3ee81df2008-05-17 18:14:43 +000010613- PEP 3123: Provide forward compatibility with Python 3.0, while
10614 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10615 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010616
Georg Brandl3ee81df2008-05-17 18:14:43 +000010617- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10618 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010619
10620- Patch #1733960: Allow T_LONGLONG to accept ints.
10621
10622- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10623
Christian Heimes000a0742008-01-03 22:16:32 +000010624- Added a new API function ``PyImport_ImportModuleNoBlock``.
10625
Georg Brandl6caad7d2008-01-26 14:19:22 +000010626- Bug #1637022: Prefix AST symbols with _Py_.
10627
10628- Fix some leftovers from the conversion from int to Py_ssize_t
10629 (relevant to strings and sequences of more than 2**31 items).
10630
10631- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10632 outside of pystate.c and should not be necessary.
10633
Georg Brandl3ee81df2008-05-17 18:14:43 +000010634- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10635 absolute imports. In earlier versions they might have used relative
10636 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010637
Georg Brandl3ee81df2008-05-17 18:14:43 +000010638- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10639 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010640
Georg Brandl3ee81df2008-05-17 18:14:43 +000010641- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10642 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010647- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10648 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10649 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10650 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010651
Georg Brandl3ee81df2008-05-17 18:14:43 +000010652- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +000010662- buildtools now raises a DeprecationWarning.
10663
Georg Brandl3ee81df2008-05-17 18:14:43 +000010664- Removed the macfs module. It had been deprecated since Python 2.5.
10665 This lead to the deprecation of macostools.touched() as it relied
10666 solely on macfs and was a no-op under OS X.
