918
919- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
920 and later systems as is currently done for Python 3.x installers.
921 For 2.7.7 only, we will provide three installers:
922 the legacy deprecated 10.3+ 32-bit-only format;
923 the newer 10.5+ 32-bit-only format;
924 and the unchanged 10.6+ 64-/32-bit format.
925 Although binary installers will no longer be available from
926 python.org as of 2.7.8, it will still be possible to build from
927 source on 10.3.9 and 10.4 systems if necessary.
928 See Mac/BuildScript/README.txt for more information.

2310 32-bit-only installer Pythons on systems with Xcode 4 (currently
2311 OS X 10.8, 10.7, and optionally 10.6).
2312 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2313 * Since Xcode 4 removes ppc support, extension module builds now
2314 check for ppc compiler support and by default remove ppc and
2315 ppc64 archs when they are not available.
2316 * Extension module builds now revert to using system installed
2317 headers and libs (/usr and /System/Library) if the SDK used
2318 to build the interpreter is not installed or has moved.
2319 * Try to avoid building extension modules with deprecated
2320 and problematic Apple llvm-gcc compiler. If original compiler
2321 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002758- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002759 has left two versions of customize_compiler, the original in
2760 distutils.sysconfig and another copy in distutils.ccompiler, with some
2761 parts of distutils calling one and others using the other.

2763 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002765- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2766 Distutils-based packages with C extension modules may fail because
2767 Apple has removed gcc-4.2, the version used to build python.org
2768 64-bit/32-bit Pythons. If the user does not explicitly override
2769 the default C compiler by setting the CC environment variable,
2770 Distutils will now attempt to compile extension modules with clang
2771 if gcc-4.2 is required but not found. Also as a convenience, if
2772 the user does explicitly set CC, substitute its value as the default
2773 compiler in the Distutils LDSHARED configuration variable for OS X.
2774 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2775 SDK, neither of which are available in Xcode 4. This change does not
2776 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003026- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3027 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3028 interpreter process. This could cause failures in non-Distutils subprocesses
3029 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003030 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003031 deployment target only in the environment of each build subprocess. It is
3032 still possible to globally override the default by setting
3033 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3034 greater or equal to the default value, the value with which the interpreter
3035 was built.

3064 updating the check interval, so if the user decreases the check interval,
3065 the ticker doesn't have to wind down to zero from the old starting point
3066 before the new interval takes effect. And if the user increases the
3067 interval, it makes sure the new limit takes effect right away rather have an
3068 early task switch before recognizing the new interval.

4064
Raymond Hettinger20397532010-09-12 02:11:45 +00004065- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4066 This prevents user-created self-referencing ordered dictionaries from
4067 becoming permanently uncollectable GC garbage. The downside is that
4068 removing __del__ means that the internal doubly-linked list has to wait for
4069 GC collection rather than freeing memory immediately when the refcnt drops
4070 to zero.

4075
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004076- Issue #9792: In case of connection failure, socket.create_connection()

4078 to fetch the original errno, or to filter timeout errors. Now the
4079 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004528- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4529 start byte and the continuation byte(s) are now considered invalid, instead
4530 of the number of bytes specified by the start byte.
4531 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4532 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4533 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4534 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004542- Issue #8748: Fix two issues with comparisons between complex and integer
4543 objects. (1) The comparison could incorrectly return True in some cases
4544 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4545 (2) The comparison raised an OverflowError for large integers, leading
4546 to unpredictable exceptions when combining integers and complex objects

4930 with a non-empty format string. This is an effort to future-proof user
4931 code. If a derived class does not currently implement __format__ but later
4932 adds its own __format__, it would most likely break user code that had

Georg Brandlba83f822010-03-14 09:50:54 +00005427 file position when calling `truncate()`. It would previously change the file
5428 position to the given argument, which goes against the tradition of

5435 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5524-----------------
5525
Georg Brandlba83f822010-03-14 09:50:54 +00005526- The ``__complex__()`` method is now looked up on the class of instances to
5527 make it consistent with other special methods.

5531
Mark Dickinson1b34d252010-01-01 17:27:30 +00005532- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005533 DeprecationWarning when passed a float argument where an integer was expected.
5534 These functions and methods now raise TypeError instead. The majority of the
5535 effects of this change are in the extension modules, but some core functions
5536 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5537 and many unicode/str methods.

5551 of integers: the result of a/b is now correctly rounded for ints a and b (at
5552 least on IEEE 754 platforms), and in particular does not depend on the
5553 internal representation of a long.

5561
Georg Brandlba83f822010-03-14 09:50:54 +00005562 These executables now work properly with the arch(1) command: ``arch -ppc

5649 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5650 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5651 float arguments for integer format codes (other than 'L'): previously an
5652 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5653 TypeError. For the 'L' format code (which previously had no warning) there is
5654 now a DeprecationWarning.

5703 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005704

5706 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005718
Georg Brandlba83f822010-03-14 09:50:54 +00005719- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5720 decimal string that's guaranteed to round back to x under correct rounding
5721 (with round-half-to-even rounding mode). Previously it gave a string based on
5722 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5723 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5724 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005725
Georg Brandlba83f822010-03-14 09:50:54 +00005726- Issue #7117: On almost all platforms: float-to-string and string-to-float
5727 conversions within Python are now correctly rounded. Places these conversions
5728 occur include: str for floats and complex numbers; the float and complex
5729 constructors; old-style and new-style numeric formatting; serialization and
5730 deserialization of floats and complex numbers using marshal, pickle and json;
5731 parsing of float and imaginary literals in Python code; Decimal-to-float
5732 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005733
Georg Brandlba83f822010-03-14 09:50:54 +00005734 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5735 providing correctly-rounded strtod and dtoa C functions. This code is
5736 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5737 the C compiler. There may be a small number of platforms on which correct
5738 operation of this code cannot be guaranteed, so the code is not used: notably,
5739 this applies to platforms where the C double format is not IEEE 754 binary64,
5740 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5741 and Python's configure script is unable to determine how to change the FPU
5742 precision. On these platforms conversions use the platform strtod and dtoa,
5743 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005744
Georg Brandlba83f822010-03-14 09:50:54 +00005745- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5746 uses the correctly-rounded string <-> float conversions described above (when
5747 available), and so produces correctly rounded results that will display nicely
5748 under the float repr. There are two related small changes: (1) round now
5749 accepts any class with an ``__index__()`` method for its second argument (but
5750 no longer accepts floats for the second argument), and (2) an excessively
5751 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5752 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005882- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5883 consistent with float("1e500") and interpretation of real and imaginary
5884 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005893- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005894
Georg Brandlba83f822010-03-14 09:50:54 +00005895 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5896 (2) parsing of strings representing infinities and nans was locale aware; and
5897 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005899- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5900 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5901 but with at least one decimal point and with a default precision
5902 of 12. Previously, the behavior the same but with a default precision of 6.
5903 This more closely matches ``str()``, and reduces surprises when adding
5904 alignment flags to the empty presentation type. This also affects the new
5905 complex.__format__ in the same way.
5906
5907- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5908 classtype's, even if it was None. property now inserts the __doc__ into the
5909 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00005970 untrackable objects are not tracked by the garbage collector. This can reduce
5971 the size of collections and therefore the garbage collection overhead on

5979 internal representation of integers, for performance reasons. Base 2**30 is
5980 enabled by default on 64-bit machines. Add --enable-big-digits option to
5981 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00006129- On windows, ``os.chdir()`` given unicode was not working if

6131 this code path is really executed because I cannot move to such directory on
6132 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006134- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6135 element is temporarily replaced with an equivalent frozenset. But the
6136 eventual KeyError would always report the empty ``frozenset()`` as the missing
6137 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006157- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6158 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6159 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6160 of using the replace error handler in PyUnicode_DecodeUTF8().
6161
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006162- Issue #3739: The unicode-internal encoder now reports the number of characters

6164
Georg Brandlba83f822010-03-14 09:50:54 +00006165- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6166 allocator will be automatically disabled when running under Valgrind. This
6167 gives improved memory leak detection when running under Valgrind, while taking
6168 advantage of pymalloc at other times.

7359 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7360 neither __int__ nor __long__, TypeError used to be raised (with a
7361 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

Georg Brandlba83f822010-03-14 09:50:54 +00007415 leak-chasing test runs give sensible results. The previous method of reaping
7416 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007557- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7558
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007559- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7560 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7561 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7562 ``printf`` function, whereas PyString_FromFormat has an independent
7563 implementation and uses "%zd" on all platforms for size_t values.
7564 This makes a difference on win64, where ``printf`` needs "%Id" to display
7565 64bit values.
7566
Benjamin Peterson97179b02008-09-09 20:55:01 +00007567- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7571 object; previously an int would be returned for small values. the __long__
7572 method is allowed to return either an int or a long, but the behaviour of
7573 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007582 was correctly parsed but parsing of subsequent arguments failed.
7583
Vinay Sajip35e3b032008-09-01 14:33:59 +00007584- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007585 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7586 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7587 when given a tuple of classes as second argument, were looking up
7588 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7589 type object.

7734-----------------
7735
Guido van Rossumf8402962008-08-20 15:01:50 +00007736- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7737 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7738 extensions do not automatically benefit from the class attribute
7739 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7740 to their tp_flags field if they care. This is a backwards
7741 compatibility feature; in 3.0, all types will use the cache by
7742 default.
7743
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007744- Keyword arguments can now follow starred arguments. (``f(a, *args,
7745 keyword=23)`` is now valid syntax.)
7746
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007747- ctypes function pointers that are COM methods have a boolean True
7748 value again.

Mark Dickinsonb6467572008-08-04 21:30:09 +00007757- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7758 ValueError consistently across platforms.
7759
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007760- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7761 (64bit Unix, for example), unichr() would truncate its argument and return
7762 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00007764- Apply security patches from Apple.
7765
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007766- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00007769- Issue #1819: function calls with several named parameters are now on
7770 average 35% faster (as measured by pybench).
7771
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007772- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7773 the python debugger steps into a class statement: the free variables (local
7774 variables defined in an outer scope) would be deleted from the outer scope.
7775
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007776- Issue #2620: Overflow checking when allocating or reallocating memory
7777 was not always being done properly in some python types and extension
7778 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7779 all been updated to perform better checks and places in the code that
7780 would previously leak memory on the error path when such an allocation
7781 failed have been fixed.

7789 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7790
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007791- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7792 version reported by these tools does not necessarily follow the python
7793 version numbering scheme, so the module is less strict when parsing it.
7794
Nick Coghlanf70385a2008-08-18 12:42:46 +00007795- Issue #2235: Added Py3k warnings for types which will become unhashable
7796 under the stricter __hash__ inheritance rules in 3.0. Several types
7797 which did not meet the rules for hash invariants and were already
7798 unhashable in 3.0 have now been explicitly flagged as unhashable in
7799 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7800 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7801
Brett Cannon88f801d2008-08-18 00:46:22 +00007802- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7803 imported into the module but exposed as part of the module's API.
7804

Brett Cannonbf3157b2008-08-14 05:00:03 +00007833- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7834 since mimetools itself is deprecated. Because modules are cached, all
7835 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7836

7846 a MemoryError rather than silently stop the iteration.
7847
Guido van Rossum59ce9012008-08-09 14:55:34 +00007848- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7849 to _sre.compile() will now be rejected. This should not affect anybody
7850 since the re.compile() function never generates invalid re-bytecode.
7851
Skip Montanaroa032bf42008-08-08 22:52:51 +00007852- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7853 upon first access it can be automatically initialized from the csv file if
7854 it wasn't initialized during instantiation.
7855
Brett Cannon3aa2a492008-08-06 22:28:09 +00007856- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7857 the reload() built-in has been removed.
7858
Brett Cannon7e30b672008-08-04 21:52:25 +00007859- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007871 asking for a specific length. This problem only affected files opened
7872 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007897- Issue #3394: zipfile.writestr sets external attributes when passed a
7898 file name rather than a ZipInfo instance, so files are extracted with
7899 mode 0600 rather than 000 under Unix.
7900
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007901- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

7914 interaction with the tp_hash slot (added in 2.6b2) are now documented
7915
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007916- Issue #643841: The language reference now provides more detailed
7917 coverage of the lookup process for special methods. The disclaimers
7918 regarding lack of coverage of new-style classes have also been
7919 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007927Core and Builtins
7928-----------------
7929
Georg Brandl3e483f62008-07-16 22:57:41 +00007930- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7931 its methods now allow for items objects that can be converted to
7932 an integer using operator.index().
7933
Mark Dickinson64b7e502008-07-16 09:40:03 +00007934- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7935 produced a ValueError instead of giving the correct float.
7936
Eric Smitha5fa5a22008-07-16 00:11:49 +00007937- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7938 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7939
Mark Dickinson7103aa42008-07-15 19:08:33 +00007940- Issue #3008: the float type has a new instance method 'float.hex'
7941 and a new class method 'float.fromhex' to convert floating-point
7942 numbers to and from hexadecimal strings, respectively.
7943
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007944- Issue #2235: __hash__ is once again inherited by default. To allow
7945 collections.Hashable to remain meaningful in the presence of the
7946 default hash implementation (object.__hash__), it is now possible
7947 to explicit block inheritance of hash by setting __hash__=None at
7948 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7949 level.
7950
Nick Coghlanb028f502008-07-13 14:52:36 +00007951- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7952 the parent module cannot be found while performing an absolute import.
7953 This means that an incorrectly defined __package__ attribute will
7954 now only prevent relative imports in that module rather than causing
7955 all imports from that module to fail.
7956
Nick Coghlan14ff9942008-07-08 14:21:42 +00007957- Issue #2517: Allow unicode messages in Exceptions again by correctly
7958 bypassing the instance dictionary when looking up __unicode__ on
7959 new-style classes.
7960
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007961- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7962 set to a custom object whose write() method happens to install
7963 another file in sys.stdout.
7964
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007965- Issue #3088: Corrected a race condition in classes derived from
7966 threading.local: the first member set by a thread could be saved in
7967 another thread's dictionary.
7968
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007969- Issue #3004: Minor change to slice.indices(): the start and stop
7970 arguments are now treated identically, making the behaviour easier
7971 to describe and understand. For example, slice(None, -10,
7972 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7973 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7974 10, -1).
7975
Georg Brandl278fc502008-07-19 12:46:12 +00007976- Issue #3219: Calling a function with repeated keyword arguments,
7977 f(a=2, a=23), would not cause a syntax error. This was a regression
7978 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007979
Georg Brandl278fc502008-07-19 12:46:12 +00007980- Issue #2862: Make int and float freelist management consistent with
7981 other freelists. Changes their CompactFreeList apis into
7982 ClearFreeList apis and calls them via gc.collect().

7989 error when they failed.
7990
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007991- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008016- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8017 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008018 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008019 content-length. The problem had been corrected in the 2.4 branch, but never
8020 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008035- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8037
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008038- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00008426 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008427
8428 This is controlled by the configure argument ``--with-universal-archs``:
8429
8430 - ``--with-universal-archs=all``: install 4-way universal
8431
8432 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8433
8434 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8435
8436 This option should be used in combination with ``--enable-universalsdk=``.
8437
8438 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 +00008487- Issue #1631171: Re-implement the 'warnings' module in C (the
8488 original Python code has been kept as backup). This will allow for
8489 using the 'warning's machinery in such places as the parser where
8490 use of pure Python code is not possible. Both the ``showarning()``
8491 and ``formatwarning()`` gain an optional 'line' argument which is
8492 not called by default for backwards-compatibility reasons. Setting
8493 ``warnings.showwarning()`` to an implementation that lacks support
8494 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008557- Issue #2550: The approach used by client/server code for obtaining
8558 ports to listen on in network-oriented tests has been refined in an
8559 effort to facilitate running multiple instances of the entire
8560 regression test suite in parallel without issue.
8561 test_support.bind_port() has been fixed such that it will always
8562 return a unique port -- which wasn't always the case with the
8563 previous implementation, especially if socket options had been set
8564 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8565 new implementation of bind_port() will actually raise an exception
8566 if it is passed an AF_INET/SOCK_STREAM socket with either the
8567 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8568 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8569 the socket it's been passed. This currently only applies to
8570 Windows. This option prevents any other sockets from binding to the
8571 host/port we've bound to, thus removing the possibility of the
8572 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8573 when a second SOCK_STREAM socket binds and accepts to a host/port
8574 that's already been bound by another socket. The optional preferred
8575 port parameter to bind_port() has been removed. Under no
8576 circumstances should tests be hard coding ports!
8577
8578 test_support.find_unused_port() has also been introduced, which will
8579 pass a temporary socket object to bind_port() in order to obtain an
8580 unused port. The temporary socket object is then closed and
8581 deleted, and the port is returned. This method should only be used
8582 for obtaining an unused port in order to pass to an external program
8583 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8584 a parameter to a server-oriented class that doesn't give you direct
8585 access to the underlying socket used.
8586
8587 Finally, test_support.HOST has been introduced, which should be used
8588 for the host argument of any relevant socket calls (i.e. bind and
8589 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008590
8591 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008593 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8594 test_asynchat and test_socket_ssl.

Facundo Batistafc2d0102008-02-23 12:01:13 +00008875
Eric Smitha73fbe72008-02-23 03:09:44 +00008876- Added the future_builtins module, which contains hex() and oct().
8877 These are the PEP 3127 version of these functions, designed to be
8878 compatible with the hex() and oct() builtins from Python 3.0. They
8879 differ slightly in their output formats from the existing, unchanged
8880 Python 2.6 builtins. The expected usage of the future_builtins
8881 module is:
8882 from future_builtins import hex, oct
8883
Eric Smith7ef40bf2008-02-20 23:34:22 +00008884- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8885 exponents for exponents with absolute value < 100. Follows C99
8886 standard. This is a change on Windows, which would use 3 digits.
8887 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8888 so that any alterations it does to the resulting string will be
8889 available in stringlib/formatter.h (for float.__format__).
8890
Eric Smith5a3c1352008-02-19 13:21:56 +00008891- Implemented PEP 3101, Advanced String Formatting. This adds a new
8892 builtin format(); a format() method for str and unicode; a
8893 __format__() method to object, str, unicode, int, long, float, and
8894 datetime; the class string.Formatter; and the C API
8895 PyObject_Format().
8896
Georg Brandl3ee81df2008-05-17 18:14:43 +00008897- Fixed several potential crashes, all caused by specially crafted
8898 __del__ methods exploiting objects in temporarily inconsistent
8899 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008901- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008902 prevent a possible crash: an Abstract Base Class would try to access
8903 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008904

Georg Brandl3ee81df2008-05-17 18:14:43 +00008908- Clear all free lists during a gc.collect() of the highest generation
8909 in order to allow pymalloc to free more arenas. Python may give back
8910 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008911
Georg Brandl3ee81df2008-05-17 18:14:43 +00008912- Issue #2045: Fix an infinite recursion triggered when printing a
8913 subclass of collections.defaultdict, if its default_factory is set
8914 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00008916- Fixed a minor memory leak in dictobject.c. The content of the free
8917 list was not freed on interpreter shutdown.
8918
Georg Brandl21e99f42010-03-07 15:23:59 +00008919- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008920 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008921
Georg Brandl3ee81df2008-05-17 18:14:43 +00008922- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8923 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008924 to compact the internal free lists of pre-allocted ints and floats.
8925
Georg Brandl3ee81df2008-05-17 18:14:43 +00008926- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8927 calls. Python expected the return type int but the fork familie
8928 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008942- Patch #1473257: generator objects gain a gi_code attribute. This is
8943 the same object as the func_code attribute of the function that
8944 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008945
Georg Brandl3ee81df2008-05-17 18:14:43 +00008946- Issue #1920: "while 0" statements were completely removed by the
8947 compiler, even in the presence of an "else" clause, which is
8948 supposed to be run when the condition is false. Now the compiler
8949 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008950
Guido van Rossumeead05f2008-01-24 18:21:02 +00008951- A few crashers fixed: weakref_in_del.py (issue #1377858);
8952 loosing_dict_ref.py (issue #1303614, test67.py);
8953 borrowed_ref_[34].py (not in tracker).
8954
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008955- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008956 suppressed while an extension is loaded by calling SetErrorMode in
8957 dynload_win.c. The error is still reported properly.
8958
Georg Brandl3ee81df2008-05-17 18:14:43 +00008959- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008960 several extension methods and modules do not work without unicode
8961 support.
8962
Georg Brandl26543b12008-01-21 18:36:51 +00008963- Issue #1882: when compiling code from a string, encoding cookies in the

8967
Georg Brandl6caad7d2008-01-26 14:19:22 +00008968- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008969 added.
8970
Christian Heimesc94e2b52008-01-14 04:13:37 +00008971- sys.float_info / PyFloat_GetInfo: The floating point information
8972 object was converted from a dict to a specialized structseq object.
8973
Georg Brandl3ee81df2008-05-17 18:14:43 +00008974- Patch #1816: Added sys.flags structseq. It exposes the status of
8975 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008976
Georg Brandl3ee81df2008-05-17 18:14:43 +00008977- Objects/structseq.c: Implemented new structseq representation. The
8978 patch makes structseqs (e.g. the return value of os.stat) more
8979 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008980
Georg Brandl3ee81df2008-05-17 18:14:43 +00008981- Patch #1700288: added a type attribute cache that caches method
8982 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008983
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008984- Bug #1776: __import__() no longer accepts filenames on any platform.

8990 envvar and sys.dont_write_bytecode attribute. All these can be set
8991 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008992
Georg Brandl3ee81df2008-05-17 18:14:43 +00008993- Improve some exception messages when Windows fails to load an
8994 extension module. Now we get for example '%1 is not a valid Win32
8995 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009002- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009003 and INF. float("nan"), float("inf") and float("-inf") now work on
9004 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009005
Georg Brandl3ee81df2008-05-17 18:14:43 +00009006- Compiler now generates simpler and faster code for dictionary
9007 literals. The oparg for BUILD_MAP now indicates an estimated
9008 dictionary size. There is a new opcode, STORE_MAP, for adding
9009 entries to the dictionary.

9052
Georg Brandl21e99f42010-03-07 15:23:59 +00009053- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009054 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9055 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009056
Georg Brandl3ee81df2008-05-17 18:14:43 +00009057- Issue #1686386: Tuple's tp_repr did not take into account the
9058 possibility of having a self-referential tuple, which is possible
9059 from C code. Nor did object's tp_str consider that a type's tp_str
9060 could do something that could lead to an inifinite recursion.
9061 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9062 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009063
Georg Brandl3ee81df2008-05-17 18:14:43 +00009064- Issue #1164: It was possible to trigger deadlock when using the
9065 'print' statement to write to a file since the GIL was not released
9066 as needed. Now PyObject_Print() does the right thing along with
9067 various tp_print implementations of the built-in types and those in
9068 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009069
Georg Brandl3ee81df2008-05-17 18:14:43 +00009070- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009077- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009078 PyObject_Call() never calling back out to Python code to trigger
9079 recursion depth updates/checks. Required the creation of a static
9080 RuntimeError instance in case normalizing an exception put the
9081 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00009108 "except E as target:". This is to provide forwards compatibility
9109 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009116- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009117 setting a plain string, ie don't expand to single letter identifiers.
9118
Raymond Hettinger13936692007-04-11 18:40:58 +00009119- Request #1191699: Slices can now be pickled.

9129
Guido van Rossum143b5642007-03-23 04:58:42 +00009130- Bug #1683368: The object.__init__() and object.__new__() methods are
9131 now stricter in rejecting excess arguments. The only time when
9132 either allows excess arguments is when it is not overridden and the
9133 other one is. For backwards compatibility, when both are
9134 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009135 warning later). Also, type.__init__() insists on the same signature
9136 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9139 object to complex using its __complex__() method before falling back
9140 to the __float__() method. Therefore, the functions in the cmath
9141 module now can operate on objects that define a __complex__()
9142 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009160- Bug #1678647: write a newline after printing an exception in any
9161 case, even when converting the value to a string failed.
9162
Georg Brandl871f1bc2007-03-12 13:17:36 +00009163- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009164 its argument, if it exists. If not, it will work like before. This
9165 allows customizing the output of dir() in the presence of a
9166 __getattr__().

9176 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00009178- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179 makes the filenames the warning module prints much more sensible
9180 when a PYTHONSTARTUP file is used.

9194 sq_ass_slice instead of the sq_slice slot.
9195
Georg Brandl3ee81df2008-05-17 18:14:43 +00009196- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00009299 generator expressions (x for x, in ... ) works again. Fixing this

9822 TestCase and TestSuite subclasses (not instances) are no longer

10095 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010096
Georg Brandl3ee81df2008-05-17 18:14:43 +000010097- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010106- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010107 that the SMTP.starttls() caller no longer needs to call ehlo()
10108 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010109 does not claim to support starttls. Adds the
10110 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010153- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010154 works as expected. ``mmap.find`` also takes an optional ``end``

10191 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10192 silently miscode subclasses of those types. Now, it raises a
10193 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010194

Georg Brandl3ee81df2008-05-17 18:14:43 +000010209 time so that opening a database previously created with the DB_DUP
10210 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10211 opens. Specifically: dictionary assignment to a DB object will
10212 replace all values for a given key when the database allows
10213 duplicate values. DB users should use DB.put(k, v) when they want
10214 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010215

10221 characters with ASCII value less than 32. Also, it correctly quotes
10222 dots only if they occur on a single line, as opposed to the previous
10223 behavior of quoting dots if they are the second character of any
10224 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010225

Georg Brandl3ee81df2008-05-17 18:14:43 +000010559- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10560 to ``PyTuple_SetItem``, it can be used to populate a brand new
10561 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010565- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10566 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10567 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010568
10569- Patch #1720595: add T_BOOL to the range of structmember types.
10570
10571- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10572 ``PyFloat_GetInfo()`` to the float API.
10573
Georg Brandl3ee81df2008-05-17 18:14:43 +000010574- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10575 of w# format code incorrectly truncated the length to an int, even
10576 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10577 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010578
Georg Brandl3ee81df2008-05-17 18:14:43 +000010579- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10580 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010582- PEP 3123: Provide forward compatibility with Python 3.0, while
10583 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10584 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010585
Georg Brandl3ee81df2008-05-17 18:14:43 +000010586- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10587 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010588
10589- Patch #1733960: Allow T_LONGLONG to accept ints.
10590
10591- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10592
Christian Heimes000a0742008-01-03 22:16:32 +000010593- Added a new API function ``PyImport_ImportModuleNoBlock``.
10594
Georg Brandl6caad7d2008-01-26 14:19:22 +000010595- Bug #1637022: Prefix AST symbols with _Py_.
10596
10597- Fix some leftovers from the conversion from int to Py_ssize_t
10598 (relevant to strings and sequences of more than 2**31 items).
10599
10600- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10601 outside of pystate.c and should not be necessary.
10602
Georg Brandl3ee81df2008-05-17 18:14:43 +000010603- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10604 absolute imports. In earlier versions they might have used relative
10605 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010606
Georg Brandl3ee81df2008-05-17 18:14:43 +000010607- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10608 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010609
Georg Brandl3ee81df2008-05-17 18:14:43 +000010610- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10611 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010616- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10617 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10618 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10619 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010620
Georg Brandl3ee81df2008-05-17 18:14:43 +000010621- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10622 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010633- Removed the macfs module. It had been deprecated since Python 2.5.
10634 This lead to the deprecation of macostools.touched() as it relied
10635 solely on macfs and was a no-op under OS X.
