926
927- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
928 and later systems as is currently done for Python 3.x installers.
929 For 2.7.7 only, we will provide three installers:
930 the legacy deprecated 10.3+ 32-bit-only format;
931 the newer 10.5+ 32-bit-only format;
932 and the unchanged 10.6+ 64-/32-bit format.
933 Although binary installers will no longer be available from
934 python.org as of 2.7.8, it will still be possible to build from
935 source on 10.3.9 and 10.4 systems if necessary.

Ned Deilyf84b5312013-10-25 00:44:46 -07001264- Issue #19019: Change the OS X installer build script to use CFLAGS instead
1265 of OPT for special build options. By setting OPT, some compiler-specific
1266 options like -fwrapv were overridden and thus not used, which could result

2317 In particular, fix extension module build failures when trying to use
2318 32-bit-only installer Pythons on systems with Xcode 4 (currently
2319 OS X 10.8, 10.7, and optionally 10.6).
2320 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2321 * Since Xcode 4 removes ppc support, extension module builds now
2322 check for ppc compiler support and by default remove ppc and
2323 ppc64 archs when they are not available.
2324 * Extension module builds now revert to using system installed
2325 headers and libs (/usr and /System/Library) if the SDK used
2326 to build the interpreter is not installed or has moved.
2327 * Try to avoid building extension modules with deprecated
2328 and problematic Apple llvm-gcc compiler. If original compiler
2329 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002766- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002767 has left two versions of customize_compiler, the original in
2768 distutils.sysconfig and another copy in distutils.ccompiler, with some

2771 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002773- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2774 Distutils-based packages with C extension modules may fail because
2775 Apple has removed gcc-4.2, the version used to build python.org
2776 64-bit/32-bit Pythons. If the user does not explicitly override
2777 the default C compiler by setting the CC environment variable,
2778 Distutils will now attempt to compile extension modules with clang
2779 if gcc-4.2 is required but not found. Also as a convenience, if
2780 the user does explicitly set CC, substitute its value as the default
2781 compiler in the Distutils LDSHARED configuration variable for OS X.
2782 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2783 SDK, neither of which are available in Xcode 4. This change does not
2784 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003034- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3035 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3036 interpreter process. This could cause failures in non-Distutils subprocesses
3037 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003038 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003039 deployment target only in the environment of each build subprocess. It is
3040 still possible to globally override the default by setting
3041 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3042 greater or equal to the default value, the value with which the interpreter
3043 was built.

3072 updating the check interval, so if the user decreases the check interval,
3073 the ticker doesn't have to wind down to zero from the old starting point
3074 before the new interval takes effect. And if the user increases the
3075 interval, it makes sure the new limit takes effect right away rather have an
3076 early task switch before recognizing the new interval.

4072
Raymond Hettinger20397532010-09-12 02:11:45 +00004073- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4074 This prevents user-created self-referencing ordered dictionaries from
4075 becoming permanently uncollectable GC garbage. The downside is that
4076 removing __del__ means that the internal doubly-linked list has to wait for
4077 GC collection rather than freeing memory immediately when the refcnt drops
4078 to zero.

4083
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004084- Issue #9792: In case of connection failure, socket.create_connection()

4086 to fetch the original errno, or to filter timeout errors. Now the
4087 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004536- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4537 start byte and the continuation byte(s) are now considered invalid, instead
4538 of the number of bytes specified by the start byte.
4539 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4540 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4541 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4542 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004550- Issue #8748: Fix two issues with comparisons between complex and integer
4551 objects. (1) The comparison could incorrectly return True in some cases
4552 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4553 (2) The comparison raised an OverflowError for large integers, leading
4554 to unpredictable exceptions when combining integers and complex objects
4555 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004557- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00005435 file position when calling `truncate()`. It would previously change the file
5436 position to the given argument, which goes against the tradition of

5440 class used to represent files stored inside an archive. The new
5441 implementation is significantly faster and can be wrapped in a
5442 ``io.BufferedReader`` object for more speedups. It also solves an issue
5443 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5532-----------------
5533
Georg Brandlba83f822010-03-14 09:50:54 +00005534- The ``__complex__()`` method is now looked up on the class of instances to
5535 make it consistent with other special methods.

5539
Mark Dickinson1b34d252010-01-01 17:27:30 +00005540- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005541 DeprecationWarning when passed a float argument where an integer was expected.
5542 These functions and methods now raise TypeError instead. The majority of the
5543 effects of this change are in the extension modules, but some core functions
5544 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5545 and many unicode/str methods.

5559 of integers: the result of a/b is now correctly rounded for ints a and b (at
5560 least on IEEE 754 platforms), and in particular does not depend on the
5561 internal representation of a long.

5569
Georg Brandlba83f822010-03-14 09:50:54 +00005570 These executables now work properly with the arch(1) command: ``arch -ppc
5571 python`` will start a universal binary version of python in PPC mode (unlike

5657 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5658 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5659 float arguments for integer format codes (other than 'L'): previously an
5660 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5661 TypeError. For the 'L' format code (which previously had no warning) there is
5662 now a DeprecationWarning.

5711 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005712
Georg Brandlba83f822010-03-14 09:50:54 +00005713- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5714 1e50 in absolute value.

5717 1e-100 used to raise OverflowError, but now gives the requested 120
5718 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005726
Georg Brandlba83f822010-03-14 09:50:54 +00005727- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5728 decimal string that's guaranteed to round back to x under correct rounding
5729 (with round-half-to-even rounding mode). Previously it gave a string based on
5730 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5731 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5732 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005733
Georg Brandlba83f822010-03-14 09:50:54 +00005734- Issue #7117: On almost all platforms: float-to-string and string-to-float
5735 conversions within Python are now correctly rounded. Places these conversions
5736 occur include: str for floats and complex numbers; the float and complex
5737 constructors; old-style and new-style numeric formatting; serialization and
5738 deserialization of floats and complex numbers using marshal, pickle and json;
5739 parsing of float and imaginary literals in Python code; Decimal-to-float
5740 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005741
Georg Brandlba83f822010-03-14 09:50:54 +00005742 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5743 providing correctly-rounded strtod and dtoa C functions. This code is
5744 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5745 the C compiler. There may be a small number of platforms on which correct
5746 operation of this code cannot be guaranteed, so the code is not used: notably,
5747 this applies to platforms where the C double format is not IEEE 754 binary64,
5748 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5749 and Python's configure script is unable to determine how to change the FPU
5750 precision. On these platforms conversions use the platform strtod and dtoa,
5751 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005752
Georg Brandlba83f822010-03-14 09:50:54 +00005753- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5754 uses the correctly-rounded string <-> float conversions described above (when
5755 available), and so produces correctly rounded results that will display nicely
5756 under the float repr. There are two related small changes: (1) round now
5757 accepts any class with an ``__index__()`` method for its second argument (but
5758 no longer accepts floats for the second argument), and (2) an excessively
5759 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5760 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005890- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5891 consistent with float("1e500") and interpretation of real and imaginary
5892 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005901- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005902
Georg Brandlba83f822010-03-14 09:50:54 +00005903 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5904 (2) parsing of strings representing infinities and nans was locale aware; and
5905 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005906
Georg Brandlba83f822010-03-14 09:50:54 +00005907- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5908 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5909 but with at least one decimal point and with a default precision
5910 of 12. Previously, the behavior the same but with a default precision of 6.
5911 This more closely matches ``str()``, and reduces surprises when adding
5912 alignment flags to the empty presentation type. This also affects the new
5913 complex.__format__ in the same way.
5914
5915- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5916 classtype's, even if it was None. property now inserts the __doc__ into the
5917 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005977- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005978 untrackable objects are not tracked by the garbage collector. This can reduce
5979 the size of collections and therefore the garbage collection overhead on

5987 internal representation of integers, for performance reasons. Base 2**30 is
5988 enabled by default on 64-bit machines. Add --enable-big-digits option to
5989 configure, which overrides the default. Add sys.long_info structseq to
5990 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006137- On windows, ``os.chdir()`` given unicode was not working if

6139 this code path is really executed because I cannot move to such directory on
6140 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006142- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6143 element is temporarily replaced with an equivalent frozenset. But the
6144 eventual KeyError would always report the empty ``frozenset()`` as the missing
6145 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006165- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6166 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6167 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6168 of using the replace error handler in PyUnicode_DecodeUTF8().
6169
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006170- Issue #3739: The unicode-internal encoder now reports the number of characters

6172
Georg Brandlba83f822010-03-14 09:50:54 +00006173- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6174 allocator will be automatically disabled when running under Valgrind. This
6175 gives improved memory leak detection when running under Valgrind, while taking
6176 advantage of pymalloc at other times.

7366 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
7367 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7368 neither __int__ nor __long__, TypeError used to be raised (with a
7369 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7370 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00007423 leak-chasing test runs give sensible results. The previous method of reaping
7424 threads could return successfully while some Thread objects were still
7425 referenced. This also introduces a new private function: ``thread._count()``.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007565- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7566
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007567- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7568 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7569 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7570 ``printf`` function, whereas PyString_FromFormat has an independent
7571 implementation and uses "%zd" on all platforms for size_t values.
7572 This makes a difference on win64, where ``printf`` needs "%Id" to display
7573 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007575- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7579 object; previously an int would be returned for small values. the __long__
7580 method is allowed to return either an int or a long, but the behaviour of
7581 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007590 was correctly parsed but parsing of subsequent arguments failed.
7591
Vinay Sajip35e3b032008-09-01 14:33:59 +00007592- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007593 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7594 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7595 when given a tuple of classes as second argument, were looking up
7596 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7597 type object.

7742-----------------
7743
Guido van Rossumf8402962008-08-20 15:01:50 +00007744- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7745 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7746 extensions do not automatically benefit from the class attribute
7747 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7748 to their tp_flags field if they care. This is a backwards
7749 compatibility feature; in 3.0, all types will use the cache by
7750 default.
7751
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007752- Keyword arguments can now follow starred arguments. (``f(a, *args,

7754
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007755- ctypes function pointers that are COM methods have a boolean True
7756 value again.

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007768- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7769 (64bit Unix, for example), unichr() would truncate its argument and return
7770 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

7779
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007780- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7781 the python debugger steps into a class statement: the free variables (local
7782 variables defined in an outer scope) would be deleted from the outer scope.
7783
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007784- Issue #2620: Overflow checking when allocating or reallocating memory
7785 was not always being done properly in some python types and extension
7786 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7787 all been updated to perform better checks and places in the code that
7788 would previously leak memory on the error path when such an allocation
7789 failed have been fixed.

7797 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7798
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007799- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7800 version reported by these tools does not necessarily follow the python
7801 version numbering scheme, so the module is less strict when parsing it.
7802
Nick Coghlanf70385a2008-08-18 12:42:46 +00007803- Issue #2235: Added Py3k warnings for types which will become unhashable
7804 under the stricter __hash__ inheritance rules in 3.0. Several types
7805 which did not meet the rules for hash invariants and were already
7806 unhashable in 3.0 have now been explicitly flagged as unhashable in
7807 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7808 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7809
Brett Cannon88f801d2008-08-18 00:46:22 +00007810- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7811 imported into the module but exposed as part of the module's API.
7812

Brett Cannonbf3157b2008-08-14 05:00:03 +00007841- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7842 since mimetools itself is deprecated. Because modules are cached, all
7843 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7844

7854 a MemoryError rather than silently stop the iteration.
7855
Guido van Rossum59ce9012008-08-09 14:55:34 +00007856- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7857 to _sre.compile() will now be rejected. This should not affect anybody
7858 since the re.compile() function never generates invalid re-bytecode.
7859
Skip Montanaroa032bf42008-08-08 22:52:51 +00007860- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7861 upon first access it can be automatically initialized from the csv file if
7862 it wasn't initialized during instantiation.
7863
Brett Cannon3aa2a492008-08-06 22:28:09 +00007864- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7865 the reload() built-in has been removed.
7866
Brett Cannon7e30b672008-08-04 21:52:25 +00007867- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007879 asking for a specific length. This problem only affected files opened
7880 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007905- Issue #3394: zipfile.writestr sets external attributes when passed a
7906 file name rather than a ZipInfo instance, so files are extracted with
7907 mode 0600 rather than 000 under Unix.
7908
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007909- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7910 argument in python 2.5, this broke code that subclassed Popen to include its

7922 interaction with the tp_hash slot (added in 2.6b2) are now documented
7923
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007924- Issue #643841: The language reference now provides more detailed
7925 coverage of the lookup process for special methods. The disclaimers
7926 regarding lack of coverage of new-style classes have also been
7927 removed, since the coverage is now fairly reasonable.

7931================================
7932
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007933*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007935Core and Builtins
7936-----------------
7937
Georg Brandl3e483f62008-07-16 22:57:41 +00007938- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7939 its methods now allow for items objects that can be converted to
7940 an integer using operator.index().
7941
Mark Dickinson64b7e502008-07-16 09:40:03 +00007942- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7943 produced a ValueError instead of giving the correct float.
7944
Eric Smitha5fa5a22008-07-16 00:11:49 +00007945- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7946 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7947
Mark Dickinson7103aa42008-07-15 19:08:33 +00007948- Issue #3008: the float type has a new instance method 'float.hex'
7949 and a new class method 'float.fromhex' to convert floating-point
7950 numbers to and from hexadecimal strings, respectively.
7951
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007952- Issue #2235: __hash__ is once again inherited by default. To allow
7953 collections.Hashable to remain meaningful in the presence of the
7954 default hash implementation (object.__hash__), it is now possible
7955 to explicit block inheritance of hash by setting __hash__=None at
7956 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7957 level.
7958
Nick Coghlanb028f502008-07-13 14:52:36 +00007959- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7960 the parent module cannot be found while performing an absolute import.
7961 This means that an incorrectly defined __package__ attribute will
7962 now only prevent relative imports in that module rather than causing
7963 all imports from that module to fail.
7964
Nick Coghlan14ff9942008-07-08 14:21:42 +00007965- Issue #2517: Allow unicode messages in Exceptions again by correctly
7966 bypassing the instance dictionary when looking up __unicode__ on
7967 new-style classes.
7968
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007969- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7970 set to a custom object whose write() method happens to install
7971 another file in sys.stdout.
7972
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007973- Issue #3088: Corrected a race condition in classes derived from
7974 threading.local: the first member set by a thread could be saved in
7975 another thread's dictionary.
7976
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007977- Issue #3004: Minor change to slice.indices(): the start and stop
7978 arguments are now treated identically, making the behaviour easier
7979 to describe and understand. For example, slice(None, -10,
7980 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7981 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7982 10, -1).
7983
Georg Brandl278fc502008-07-19 12:46:12 +00007984- Issue #3219: Calling a function with repeated keyword arguments,
7985 f(a=2, a=23), would not cause a syntax error. This was a regression
7986 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007987
Georg Brandl278fc502008-07-19 12:46:12 +00007988- Issue #2862: Make int and float freelist management consistent with
7989 other freelists. Changes their CompactFreeList apis into
7990 ClearFreeList apis and calls them via gc.collect().

7996 api functions without holding the GIL, which could lead to a fatal
7997 error when they failed.
7998
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007999- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00008010- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008024- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8025 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008026 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008027 content-length. The problem had been corrected in the 2.4 branch, but never
8028 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008043- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8045
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008046- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00008434 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008435
8436 This is controlled by the configure argument ``--with-universal-archs``:
8437
8438 - ``--with-universal-archs=all``: install 4-way universal
8439
8440 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8441
8442 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8443
8444 This option should be used in combination with ``--enable-universalsdk=``.
8445
8446 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 +00008495- Issue #1631171: Re-implement the 'warnings' module in C (the
8496 original Python code has been kept as backup). This will allow for
8497 using the 'warning's machinery in such places as the parser where
8498 use of pure Python code is not possible. Both the ``showarning()``
8499 and ``formatwarning()`` gain an optional 'line' argument which is
8500 not called by default for backwards-compatibility reasons. Setting
8501 ``warnings.showwarning()`` to an implementation that lacks support
8502 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008565- Issue #2550: The approach used by client/server code for obtaining
8566 ports to listen on in network-oriented tests has been refined in an
8567 effort to facilitate running multiple instances of the entire
8568 regression test suite in parallel without issue.
8569 test_support.bind_port() has been fixed such that it will always
8570 return a unique port -- which wasn't always the case with the
8571 previous implementation, especially if socket options had been set
8572 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8573 new implementation of bind_port() will actually raise an exception
8574 if it is passed an AF_INET/SOCK_STREAM socket with either the
8575 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8576 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8577 the socket it's been passed. This currently only applies to
8578 Windows. This option prevents any other sockets from binding to the
8579 host/port we've bound to, thus removing the possibility of the
8580 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8581 when a second SOCK_STREAM socket binds and accepts to a host/port
8582 that's already been bound by another socket. The optional preferred
8583 port parameter to bind_port() has been removed. Under no
8584 circumstances should tests be hard coding ports!
8585
8586 test_support.find_unused_port() has also been introduced, which will
8587 pass a temporary socket object to bind_port() in order to obtain an
8588 unused port. The temporary socket object is then closed and
8589 deleted, and the port is returned. This method should only be used
8590 for obtaining an unused port in order to pass to an external program
8591 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8592 a parameter to a server-oriented class that doesn't give you direct
8593 access to the underlying socket used.
8594
8595 Finally, test_support.HOST has been introduced, which should be used
8596 for the host argument of any relevant socket calls (i.e. bind and
8597 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008598
8599 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008600 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008601 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8602 test_asynchat and test_socket_ssl.

Facundo Batistafc2d0102008-02-23 12:01:13 +00008883
Eric Smitha73fbe72008-02-23 03:09:44 +00008884- Added the future_builtins module, which contains hex() and oct().
8885 These are the PEP 3127 version of these functions, designed to be
8886 compatible with the hex() and oct() builtins from Python 3.0. They
8887 differ slightly in their output formats from the existing, unchanged
8888 Python 2.6 builtins. The expected usage of the future_builtins
8889 module is:
8890 from future_builtins import hex, oct
8891
Eric Smith7ef40bf2008-02-20 23:34:22 +00008892- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8893 exponents for exponents with absolute value < 100. Follows C99
8894 standard. This is a change on Windows, which would use 3 digits.
8895 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8896 so that any alterations it does to the resulting string will be
8897 available in stringlib/formatter.h (for float.__format__).
8898
Eric Smith5a3c1352008-02-19 13:21:56 +00008899- Implemented PEP 3101, Advanced String Formatting. This adds a new
8900 builtin format(); a format() method for str and unicode; a
8901 __format__() method to object, str, unicode, int, long, float, and
8902 datetime; the class string.Formatter; and the C API
8903 PyObject_Format().
8904
Georg Brandl3ee81df2008-05-17 18:14:43 +00008905- Fixed several potential crashes, all caused by specially crafted
8906 __del__ methods exploiting objects in temporarily inconsistent
8907 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008908
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008909- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008910 prevent a possible crash: an Abstract Base Class would try to access
8911 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008912

Georg Brandl3ee81df2008-05-17 18:14:43 +00008916- Clear all free lists during a gc.collect() of the highest generation
8917 in order to allow pymalloc to free more arenas. Python may give back
8918 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008919
Georg Brandl3ee81df2008-05-17 18:14:43 +00008920- Issue #2045: Fix an infinite recursion triggered when printing a
8921 subclass of collections.defaultdict, if its default_factory is set
8922 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00008924- Fixed a minor memory leak in dictobject.c. The content of the free
8925 list was not freed on interpreter shutdown.
8926
Georg Brandl21e99f42010-03-07 15:23:59 +00008927- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008928 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008929
Georg Brandl3ee81df2008-05-17 18:14:43 +00008930- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8931 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008932 to compact the internal free lists of pre-allocted ints and floats.
8933
Georg Brandl3ee81df2008-05-17 18:14:43 +00008934- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8935 calls. Python expected the return type int but the fork familie
8936 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008950- Patch #1473257: generator objects gain a gi_code attribute. This is
8951 the same object as the func_code attribute of the function that
8952 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008953
Georg Brandl3ee81df2008-05-17 18:14:43 +00008954- Issue #1920: "while 0" statements were completely removed by the
8955 compiler, even in the presence of an "else" clause, which is
8956 supposed to be run when the condition is false. Now the compiler
8957 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008958
Guido van Rossumeead05f2008-01-24 18:21:02 +00008959- A few crashers fixed: weakref_in_del.py (issue #1377858);

8961 borrowed_ref_[34].py (not in tracker).
8962
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008963- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008964 suppressed while an extension is loaded by calling SetErrorMode in
8965 dynload_win.c. The error is still reported properly.
8966
Georg Brandl3ee81df2008-05-17 18:14:43 +00008967- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008968 several extension methods and modules do not work without unicode
8969 support.
8970
Georg Brandl26543b12008-01-21 18:36:51 +00008971- Issue #1882: when compiling code from a string, encoding cookies in the

8975
Georg Brandl6caad7d2008-01-26 14:19:22 +00008976- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008977 added.
8978
Christian Heimesc94e2b52008-01-14 04:13:37 +00008979- sys.float_info / PyFloat_GetInfo: The floating point information
8980 object was converted from a dict to a specialized structseq object.
8981
Georg Brandl3ee81df2008-05-17 18:14:43 +00008982- Patch #1816: Added sys.flags structseq. It exposes the status of
8983 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008984
Georg Brandl3ee81df2008-05-17 18:14:43 +00008985- Objects/structseq.c: Implemented new structseq representation. The
8986 patch makes structseqs (e.g. the return value of os.stat) more
8987 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008988
Georg Brandl3ee81df2008-05-17 18:14:43 +00008989- Patch #1700288: added a type attribute cache that caches method
8990 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008991

8998 envvar and sys.dont_write_bytecode attribute. All these can be set
8999 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009000
Georg Brandl3ee81df2008-05-17 18:14:43 +00009001- Improve some exception messages when Windows fails to load an
9002 extension module. Now we get for example '%1 is not a valid Win32
9003 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009010- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009011 and INF. float("nan"), float("inf") and float("-inf") now work on
9012 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009013
Georg Brandl3ee81df2008-05-17 18:14:43 +00009014- Compiler now generates simpler and faster code for dictionary

9060
Georg Brandl21e99f42010-03-07 15:23:59 +00009061- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009062 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9063 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009064
Georg Brandl3ee81df2008-05-17 18:14:43 +00009065- Issue #1686386: Tuple's tp_repr did not take into account the
9066 possibility of having a self-referential tuple, which is possible
9067 from C code. Nor did object's tp_str consider that a type's tp_str
9068 could do something that could lead to an inifinite recursion.
9069 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9070 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009071
Georg Brandl3ee81df2008-05-17 18:14:43 +00009072- Issue #1164: It was possible to trigger deadlock when using the
9073 'print' statement to write to a file since the GIL was not released
9074 as needed. Now PyObject_Print() does the right thing along with
9075 various tp_print implementations of the built-in types and those in
9076 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009077

Brett Cannon1e534b52007-09-07 04:18:30 +00009085- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009086 PyObject_Call() never calling back out to Python code to trigger
9087 recursion depth updates/checks. Required the creation of a static
9088 RuntimeError instance in case normalizing an exception put the
9089 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00009116 "except E as target:". This is to provide forwards compatibility
9117 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009121- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00009124- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009125 setting a plain string, ie don't expand to single letter identifiers.
9126
Raymond Hettinger13936692007-04-11 18:40:58 +00009127- Request #1191699: Slices can now be pickled.

9137
Guido van Rossum143b5642007-03-23 04:58:42 +00009138- Bug #1683368: The object.__init__() and object.__new__() methods are
9139 now stricter in rejecting excess arguments. The only time when
9140 either allows excess arguments is when it is not overridden and the
9141 other one is. For backwards compatibility, when both are
9142 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009143 warning later). Also, type.__init__() insists on the same signature
9144 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009146- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9147 object to complex using its __complex__() method before falling back
9148 to the __float__() method. Therefore, the functions in the cmath
9149 module now can operate on objects that define a __complex__()
9150 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009168- Bug #1678647: write a newline after printing an exception in any
9169 case, even when converting the value to a string failed.
9170
Georg Brandl871f1bc2007-03-12 13:17:36 +00009171- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009172 its argument, if it exists. If not, it will work like before. This
9173 allows customizing the output of dir() in the presence of a
9174 __getattr__().

9183 parthensized forms. This means complex(repr(x)) now works instead of
9184 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009185
Georg Brandlaa2321b2007-03-07 00:40:28 +00009186- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009187 makes the filenames the warning module prints much more sensible
9188 when a PYTHONSTARTUP file is used.

9202 sq_ass_slice instead of the sq_slice slot.
9203
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- When printing an unraisable error, don't print exceptions. before

10103 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010104
Georg Brandl3ee81df2008-05-17 18:14:43 +000010105- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010114- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010115 that the SMTP.starttls() caller no longer needs to call ehlo()
10116 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010117 does not claim to support starttls. Adds the
10118 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010161- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010162 works as expected. ``mmap.find`` also takes an optional ``end``

10199 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10200 silently miscode subclasses of those types. Now, it raises a
10201 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010202

Georg Brandl3ee81df2008-05-17 18:14:43 +000010217 time so that opening a database previously created with the DB_DUP
10218 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10219 opens. Specifically: dictionary assignment to a DB object will
10220 replace all values for a given key when the database allows
10221 duplicate values. DB users should use DB.put(k, v) when they want
10222 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010223

10229 characters with ASCII value less than 32. Also, it correctly quotes
10230 dots only if they occur on a single line, as opposed to the previous
10231 behavior of quoting dots if they are the second character of any
10232 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010233

Georg Brandl3ee81df2008-05-17 18:14:43 +000010567- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10568 to ``PyTuple_SetItem``, it can be used to populate a brand new
10569 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010573- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10574 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10575 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010576
10577- Patch #1720595: add T_BOOL to the range of structmember types.
10578
10579- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10580 ``PyFloat_GetInfo()`` to the float API.
10581
Georg Brandl3ee81df2008-05-17 18:14:43 +000010582- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10583 of w# format code incorrectly truncated the length to an int, even
10584 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10585 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010586
Georg Brandl3ee81df2008-05-17 18:14:43 +000010587- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10588 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010590- PEP 3123: Provide forward compatibility with Python 3.0, while
10591 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10592 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010593
Georg Brandl3ee81df2008-05-17 18:14:43 +000010594- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10595 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010596
10597- Patch #1733960: Allow T_LONGLONG to accept ints.
10598
10599- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10600
Christian Heimes000a0742008-01-03 22:16:32 +000010601- Added a new API function ``PyImport_ImportModuleNoBlock``.
10602
Georg Brandl6caad7d2008-01-26 14:19:22 +000010603- Bug #1637022: Prefix AST symbols with _Py_.
10604
10605- Fix some leftovers from the conversion from int to Py_ssize_t
10606 (relevant to strings and sequences of more than 2**31 items).
10607
10608- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10609 outside of pystate.c and should not be necessary.
10610
Georg Brandl3ee81df2008-05-17 18:14:43 +000010611- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10612 absolute imports. In earlier versions they might have used relative
10613 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010614
Georg Brandl3ee81df2008-05-17 18:14:43 +000010615- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10616 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010617
Georg Brandl3ee81df2008-05-17 18:14:43 +000010618- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10619 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010624- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10625 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10626 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10627 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010628
Georg Brandl3ee81df2008-05-17 18:14:43 +000010629- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10630 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010641- Removed the macfs module. It had been deprecated since Python 2.5.
10642 This lead to the deprecation of macostools.touched() as it relied
10643 solely on macfs and was a no-op under OS X.
