1391 In particular, fix extension module build failures when trying to use
1392 32-bit-only installer Pythons on systems with Xcode 4 (currently
1393 OS X 10.8, 10.7, and optionally 10.6).
1394 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1395 * Since Xcode 4 removes ppc support, extension module builds now
1396 check for ppc compiler support and by default remove ppc and
1397 ppc64 archs when they are not available.
1398 * Extension module builds now revert to using system installed
1399 headers and libs (/usr and /System/Library) if the SDK used
1400 to build the interpreter is not installed or has moved.
1401 * Try to avoid building extension modules with deprecated
1402 and problematic Apple llvm-gcc compiler. If original compiler
1403 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001827- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001828 has left two versions of customize_compiler, the original in
1829 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001834- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1835 Distutils-based packages with C extension modules may fail because
1836 Apple has removed gcc-4.2, the version used to build python.org
1837 64-bit/32-bit Pythons. If the user does not explicitly override
1838 the default C compiler by setting the CC environment variable,
1839 Distutils will now attempt to compile extension modules with clang
1840 if gcc-4.2 is required but not found. Also as a convenience, if
1841 the user does explicitly set CC, substitute its value as the default
1842 compiler in the Distutils LDSHARED configuration variable for OS X.
1843 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1844 SDK, neither of which are available in Xcode 4. This change does not
1845 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002095- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2096 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2097 interpreter process. This could cause failures in non-Distutils subprocesses
2098 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002099 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002100 deployment target only in the environment of each build subprocess. It is
2101 still possible to globally override the default by setting
2102 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2103 greater or equal to the default value, the value with which the interpreter
2104 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002132- sys.setcheckinterval() now updates the current ticker count as well as
2133 updating the check interval, so if the user decreases the check interval,
2134 the ticker doesn't have to wind down to zero from the old starting point
2135 before the new interval takes effect. And if the user increases the
2136 interval, it makes sure the new limit takes effect right away rather have an
2137 early task switch before recognizing the new interval.

2963 long for a class whose __long__ method returns a plain int. This
2964 fixes an interpreter crash when initializing an instance of a long

Victor Stinnercaafd772010-09-08 10:51:01 +00002972- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2973 encoding and errors attributes instead of using utf-8 in strict mode, to get
2974 the same behaviour than the print statement.

3116
Raymond Hettinger20397532010-09-12 02:11:45 +00003117- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3118 This prevents user-created self-referencing ordered dictionaries from
3119 becoming permanently uncollectable GC garbage. The downside is that
3120 removing __del__ means that the internal doubly-linked list has to wait for
3121 GC collection rather than freeing memory immediately when the refcnt drops
3122 to zero.
3123

3127
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003128- Issue #9792: In case of connection failure, socket.create_connection()
3129 would swallow the exception and raise a new one, making it impossible
3130 to fetch the original errno, or to filter timeout errors. Now the
3131 original error is re-raised.

3135 be updated back after the system call. Original patch by Brian Brazil.

R. David Murray7c4bf552010-08-25 01:45:57 +00003153- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3154 character years even if the message contains RFC822 two character years.

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003188- Issue #9550: a BufferedReader could issue an additional read when the

3191 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003580- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3581 start byte and the continuation byte(s) are now considered invalid, instead
3582 of the number of bytes specified by the start byte.
3583 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3584 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3585 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3595 objects. (1) The comparison could incorrectly return True in some cases
3596 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

3982 with a non-empty format string. This is an effort to future-proof user
3983 code. If a derived class does not currently implement __format__ but later
3984 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003985 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003986 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004478- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004479 file position when calling `truncate()`. It would previously change the file
4480 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004481 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00004483- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4484 class used to represent files stored inside an archive. The new
4485 implementation is significantly faster and can be wrapped in a
4486 ``io.BufferedReader`` object for more speedups. It also solves an issue
4487 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004578- The ``__complex__()`` method is now looked up on the class of instances to
4579 make it consistent with other special methods.

4583
Mark Dickinson1b34d252010-01-01 17:27:30 +00004584- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004585 DeprecationWarning when passed a float argument where an integer was expected.
4586 These functions and methods now raise TypeError instead. The majority of the
4587 effects of this change are in the extension modules, but some core functions
4588 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4589 and many unicode/str methods.

4603 of integers: the result of a/b is now correctly rounded for ints a and b (at
4604 least on IEEE 754 platforms), and in particular does not depend on the
4605 internal representation of a long.

4613
Georg Brandlba83f822010-03-14 09:50:54 +00004614 These executables now work properly with the arch(1) command: ``arch -ppc

4755 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004756
Georg Brandlba83f822010-03-14 09:50:54 +00004757- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4758 1e50 in absolute value.

4762 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004770
Georg Brandlba83f822010-03-14 09:50:54 +00004771- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4772 decimal string that's guaranteed to round back to x under correct rounding
4773 (with round-half-to-even rounding mode). Previously it gave a string based on
4774 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4775 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4776 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004777
Georg Brandlba83f822010-03-14 09:50:54 +00004778- Issue #7117: On almost all platforms: float-to-string and string-to-float
4779 conversions within Python are now correctly rounded. Places these conversions
4780 occur include: str for floats and complex numbers; the float and complex
4781 constructors; old-style and new-style numeric formatting; serialization and
4782 deserialization of floats and complex numbers using marshal, pickle and json;
4783 parsing of float and imaginary literals in Python code; Decimal-to-float
4784 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004785
Georg Brandlba83f822010-03-14 09:50:54 +00004786 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4787 providing correctly-rounded strtod and dtoa C functions. This code is
4788 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4789 the C compiler. There may be a small number of platforms on which correct
4790 operation of this code cannot be guaranteed, so the code is not used: notably,
4791 this applies to platforms where the C double format is not IEEE 754 binary64,
4792 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4793 and Python's configure script is unable to determine how to change the FPU
4794 precision. On these platforms conversions use the platform strtod and dtoa,
4795 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004796
Georg Brandlba83f822010-03-14 09:50:54 +00004797- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4798 uses the correctly-rounded string <-> float conversions described above (when
4799 available), and so produces correctly rounded results that will display nicely
4800 under the float repr. There are two related small changes: (1) round now
4801 accepts any class with an ``__index__()`` method for its second argument (but
4802 no longer accepts floats for the second argument), and (2) an excessively
4803 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4804 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004945- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00004946
Georg Brandlba83f822010-03-14 09:50:54 +00004947 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4948 (2) parsing of strings representing infinities and nans was locale aware; and
4949 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004951- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4952 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4953 but with at least one decimal point and with a default precision
4954 of 12. Previously, the behavior the same but with a default precision of 6.
4955 This more closely matches ``str()``, and reduces surprises when adding
4956 alignment flags to the empty presentation type. This also affects the new
4957 complex.__format__ in the same way.
4958
4959- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4960 classtype's, even if it was None. property now inserts the __doc__ into the
4961 subclass instance __dict__.

5183 this code path is really executed because I cannot move to such directory on

5188 eventual KeyError would always report the empty ``frozenset()`` as the missing

5210 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00006387 - If x is not an int, long or float, then packing x will always result in
6388 struct.error. Previously an x with an __int__ method could be packed by
6389 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6390 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6391 neither __int__ nor __long__, TypeError used to be raised (with a
6392 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6393 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00006395 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6396 argument with an __int__ method can be packed, but use of this feature
6397 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00006446 leak-chasing test runs give sensible results. The previous method of reaping
6447 threads could return successfully while some Thread objects were still
6448 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006449
Georg Brandlba83f822010-03-14 09:50:54 +00006450- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00006467 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00006568- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006569 AttributeError instead of RuntimeError, depending in which C API call
6570 exactly the recursion limit is exceeded. Consequently, both exception types
6571 are caught and silenced.

6587
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006588- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6589
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006590- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6591 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6592 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6593 ``printf`` function, whereas PyString_FromFormat has an independent
6594 implementation and uses "%zd" on all platforms for size_t values.
6595 This makes a difference on win64, where ``printf`` needs "%Id" to display
6596 64bit values.
6597
Benjamin Peterson97179b02008-09-09 20:55:01 +00006598- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6599 error.
6600
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006601- Issue #3777: long() applied to a float object now always return a long
6602 object; previously an int would be returned for small values. the __long__
6603 method is allowed to return either an int or a long, but the behaviour of
6604 float objects should not change to respect backward compatibility.
6605
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006606- Issue #3751: str.rpartition would perform a left-partition when called with
6607 a unicode argument.
6608
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006609- Issue #3683: Fix compilation when --without-threads is given.
6610
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006611- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006612 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006613 was correctly parsed but parsing of subsequent arguments failed.
6614
Vinay Sajip35e3b032008-09-01 14:33:59 +00006615- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006616 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6617 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6618 when given a tuple of classes as second argument, were looking up
6619 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6620 type object.
6621
Neal Norwitz18aa3882008-08-24 05:04:52 +00006622- Fix crashes on memory allocation failure found with failmalloc.
6623
6624- Fix memory leaks found with valgrind and update suppressions file.
6625
6626- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6627
6628- Fix problem using wrong name in decimal module reported by pychecker.
6629
Christian Heimes7d4c3172008-08-22 19:47:25 +00006630- Silenced another compiler warning about a used but not defined
6631 function 'stringlib_contains_obj'.
6632
Benjamin Peterson712ee922008-08-24 18:10:20 +00006633- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6634 ``__delslice__``.
6635
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006636- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6637 library targets in the Makefile.
6638
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006639- Issue #1204: The configure script now tests for additional libraries
6640 that may be required when linking against readline. This fixes issues
6641 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

6652 stack usage in the case of deeply nested objects.
6653
Guido van Rossume3c4fd92008-09-10 14:27:00 +00006654- Issue #3629: Fix sre "bytecode" validator for an end case.

Nick Coghland2e09382008-09-11 12:11:06 +00006664- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00006665 return a list or None rather than a custom object.
6666
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006667- Issue #1638033: Cookie.Morsel gained the httponly attribute.
6668
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00006669- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Georg Brandl222e2082010-08-01 22:27:39 +00006690- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00006691 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6692 for catch_warnings() also led to an improvement in the raising of a
6693 DeprecationWarning related to warnings.warn_explicit().
6694
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006695- The deprecation warnings for the old camelCase threading API were removed.

6717
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006718- Issue #2975: When compiling several extension modules with Visual Studio 2008
6719 from the same python interpreter, some environment variables would grow
6720 without limit.
6721
Benjamin Peterson37346b22008-08-23 20:27:43 +00006722- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6723 exploitation of poor argument checking.
6724
Gerhard Häringef2276b2008-09-12 13:54:06 +00006725- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

6765-----------------
6766
Guido van Rossumf8402962008-08-20 15:01:50 +00006767- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6768 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6769 extensions do not automatically benefit from the class attribute
6770 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6771 to their tp_flags field if they care. This is a backwards
6772 compatibility feature; in 3.0, all types will use the cache by
6773 default.
6774
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006775- Keyword arguments can now follow starred arguments. (``f(a, *args,
6776 keyword=23)`` is now valid syntax.)
6777
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006778- ctypes function pointers that are COM methods have a boolean True
6779 value again.
6780
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006781- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6782 by denying s# to parse objects that have a releasebuffer procedure,
6783 and introducing s*.
6784
Georg Brandl1e13ea92008-08-11 09:07:59 +00006785- Issue #3537: Fix an assertion failure when an empty but presized dict
6786 object was stored in the freelist.
6787
Mark Dickinsonb6467572008-08-04 21:30:09 +00006788- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6789 ValueError consistently across platforms.
6790
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006791- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6792 (64bit Unix, for example), unichr() would truncate its argument and return
6793 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6794
Neal Norwitze7d8be82008-07-31 17:17:14 +00006795- Apply security patches from Apple.
6796
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006797- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6798 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6799
Antoine Pitrou92f82162008-07-25 22:22:08 +00006800- Issue #1819: function calls with several named parameters are now on
6801 average 35% faster (as measured by pybench).
6802
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006803- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6804 the python debugger steps into a class statement: the free variables (local
6805 variables defined in an outer scope) would be deleted from the outer scope.
6806
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006807- Issue #2620: Overflow checking when allocating or reallocating memory
6808 was not always being done properly in some python types and extension
6809 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6810 all been updated to perform better checks and places in the code that
6811 would previously leak memory on the error path when such an allocation
6812 failed have been fixed.

6816
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006817- Issue #3612: Added some missing basic types in ctypes.wintypes.
6818
Benjamin Petersone977ad42008-08-20 01:42:01 +00006819- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6820 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6821
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006822- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6823 version reported by these tools does not necessarily follow the python
6824 version numbering scheme, so the module is less strict when parsing it.
6825
Nick Coghlanf70385a2008-08-18 12:42:46 +00006826- Issue #2235: Added Py3k warnings for types which will become unhashable
6827 under the stricter __hash__ inheritance rules in 3.0. Several types
6828 which did not meet the rules for hash invariants and were already
6829 unhashable in 3.0 have now been explicitly flagged as unhashable in
6830 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6831 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6832
Brett Cannon88f801d2008-08-18 00:46:22 +00006833- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6834 imported into the module but exposed as part of the module's API.
6835
Brett Cannon7b96f072008-08-18 00:41:11 +00006836- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6837
Brett Cannon46225e72008-08-18 00:36:52 +00006838- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006840- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6841
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006842- Issue #3575: Incremental decoder's decode function now takes bytearray
6843 by using 's*' instead of 't#'.

6946
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006947- Issue #643841: The language reference now provides more detailed

6960
Georg Brandl3e483f62008-07-16 22:57:41 +00006961- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6962 its methods now allow for items objects that can be converted to
6963 an integer using operator.index().
6964
Mark Dickinson64b7e502008-07-16 09:40:03 +00006965- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6966 produced a ValueError instead of giving the correct float.
6967
Eric Smitha5fa5a22008-07-16 00:11:49 +00006968- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6969 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6970
Mark Dickinson7103aa42008-07-15 19:08:33 +00006971- Issue #3008: the float type has a new instance method 'float.hex'
6972 and a new class method 'float.fromhex' to convert floating-point
6973 numbers to and from hexadecimal strings, respectively.
6974
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006975- Issue #2235: __hash__ is once again inherited by default. To allow
6976 collections.Hashable to remain meaningful in the presence of the
6977 default hash implementation (object.__hash__), it is now possible
6978 to explicit block inheritance of hash by setting __hash__=None at
6979 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6980 level.
6981
Nick Coghlanb028f502008-07-13 14:52:36 +00006982- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6983 the parent module cannot be found while performing an absolute import.
6984 This means that an incorrectly defined __package__ attribute will
6985 now only prevent relative imports in that module rather than causing
6986 all imports from that module to fail.
6987
Nick Coghlan14ff9942008-07-08 14:21:42 +00006988- Issue #2517: Allow unicode messages in Exceptions again by correctly

6998 another thread's dictionary.
6999
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007000- Issue #3004: Minor change to slice.indices(): the start and stop
7001 arguments are now treated identically, making the behaviour easier
7002 to describe and understand. For example, slice(None, -10,
7003 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7004 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7005 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007007- Issue #3219: Calling a function with repeated keyword arguments,

7009 from 2.4 caused by the switch to the new compiler.

7048 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007049 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007050 content-length. The problem had been corrected in the 2.4 branch, but never

7456 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007457 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007458
7459 This is controlled by the configure argument ``--with-universal-archs``:
7460
7461 - ``--with-universal-archs=all``: install 4-way universal
7462
7463 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7464
7465 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7466
7467 This option should be used in combination with ``--enable-universalsdk=``.
7468
7469 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 +00007518- Issue #1631171: Re-implement the 'warnings' module in C (the
7519 original Python code has been kept as backup). This will allow for
7520 using the 'warning's machinery in such places as the parser where
7521 use of pure Python code is not possible. Both the ``showarning()``
7522 and ``formatwarning()`` gain an optional 'line' argument which is
7523 not called by default for backwards-compatibility reasons. Setting
7524 ``warnings.showwarning()`` to an implementation that lacks support
7525 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007588- Issue #2550: The approach used by client/server code for obtaining
7589 ports to listen on in network-oriented tests has been refined in an
7590 effort to facilitate running multiple instances of the entire
7591 regression test suite in parallel without issue.
7592 test_support.bind_port() has been fixed such that it will always
7593 return a unique port -- which wasn't always the case with the
7594 previous implementation, especially if socket options had been set
7595 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7596 new implementation of bind_port() will actually raise an exception
7597 if it is passed an AF_INET/SOCK_STREAM socket with either the
7598 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7599 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7600 the socket it's been passed. This currently only applies to
7601 Windows. This option prevents any other sockets from binding to the
7602 host/port we've bound to, thus removing the possibility of the
7603 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7604 when a second SOCK_STREAM socket binds and accepts to a host/port
7605 that's already been bound by another socket. The optional preferred
7606 port parameter to bind_port() has been removed. Under no
7607 circumstances should tests be hard coding ports!
7608
7609 test_support.find_unused_port() has also been introduced, which will
7610 pass a temporary socket object to bind_port() in order to obtain an
7611 unused port. The temporary socket object is then closed and
7612 deleted, and the port is returned. This method should only be used
7613 for obtaining an unused port in order to pass to an external program
7614 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7615 a parameter to a server-oriented class that doesn't give you direct
7616 access to the underlying socket used.
7617
7618 Finally, test_support.HOST has been introduced, which should be used
7619 for the host argument of any relevant socket calls (i.e. bind and
7620 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007621
7622 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007623 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007624 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7625 test_asynchat and test_socket_ssl.
7626
Georg Brandl3ee81df2008-05-17 18:14:43 +00007627 It is now possible for multiple instances of the regression test
7628 suite to run in parallel without issue.

7684 Plane. This affected raw unicode literals and the
7685 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7686 this case, like normal unicode literals and the 'unicode-escape'
7687 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007907- Added the future_builtins module, which contains hex() and oct().
7908 These are the PEP 3127 version of these functions, designed to be
7909 compatible with the hex() and oct() builtins from Python 3.0. They
7910 differ slightly in their output formats from the existing, unchanged
7911 Python 2.6 builtins. The expected usage of the future_builtins
7912 module is:
7913 from future_builtins import hex, oct
7914
Eric Smith7ef40bf2008-02-20 23:34:22 +00007915- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7916 exponents for exponents with absolute value < 100. Follows C99
7917 standard. This is a change on Windows, which would use 3 digits.
7918 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7919 so that any alterations it does to the resulting string will be
7920 available in stringlib/formatter.h (for float.__format__).
7921
Eric Smith5a3c1352008-02-19 13:21:56 +00007922- Implemented PEP 3101, Advanced String Formatting. This adds a new
7923 builtin format(); a format() method for str and unicode; a
7924 __format__() method to object, str, unicode, int, long, float, and
7925 datetime; the class string.Formatter; and the C API
7926 PyObject_Format().
7927
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928- Fixed several potential crashes, all caused by specially crafted
7929 __del__ methods exploiting objects in temporarily inconsistent

Georg Brandl3ee81df2008-05-17 18:14:43 +00007939- Clear all free lists during a gc.collect() of the highest generation
7940 in order to allow pymalloc to free more arenas. Python may give back
7941 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007942
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943- Issue #2045: Fix an infinite recursion triggered when printing a
7944 subclass of collections.defaultdict, if its default_factory is set
7945 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007946
Christian Heimesf75dbef2008-02-08 00:11:31 +00007947- Fixed a minor memory leak in dictobject.c. The content of the free
7948 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007973- Patch #1473257: generator objects gain a gi_code attribute. This is
7974 the same object as the func_code attribute of the function that
7975 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007976
Georg Brandl3ee81df2008-05-17 18:14:43 +00007977- Issue #1920: "while 0" statements were completely removed by the
7978 compiler, even in the presence of an "else" clause, which is
7979 supposed to be run when the condition is false. Now the compiler
7980 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007981
Guido van Rossumeead05f2008-01-24 18:21:02 +00007982- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007986- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007987 suppressed while an extension is loaded by calling SetErrorMode in

7989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007991 several extension methods and modules do not work without unicode
7992 support.
7993
Georg Brandl26543b12008-01-21 18:36:51 +00007994- Issue #1882: when compiling code from a string, encoding cookies in the

7998
Georg Brandl6caad7d2008-01-26 14:19:22 +00007999- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008000 added.
8001
Christian Heimesc94e2b52008-01-14 04:13:37 +00008002- sys.float_info / PyFloat_GetInfo: The floating point information
8003 object was converted from a dict to a specialized structseq object.
8004
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005- Patch #1816: Added sys.flags structseq. It exposes the status of
8006 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008007
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008- Objects/structseq.c: Implemented new structseq representation. The
8009 patch makes structseqs (e.g. the return value of os.stat) more
8010 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008011
Georg Brandl3ee81df2008-05-17 18:14:43 +00008012- Patch #1700288: added a type attribute cache that caches method
8013 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008014
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008015- Bug #1776: __import__() no longer accepts filenames on any platform.
8016 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00008018- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8019
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8021 envvar and sys.dont_write_bytecode attribute. All these can be set
8022 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008023
Georg Brandl3ee81df2008-05-17 18:14:43 +00008024- Improve some exception messages when Windows fails to load an
8025 extension module. Now we get for example '%1 is not a valid Win32
8026 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008027

Christian Heimes0a8143f2007-12-18 23:22:54 +00008033- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008034 and INF. float("nan"), float("inf") and float("-inf") now work on
8035 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008036
Georg Brandl3ee81df2008-05-17 18:14:43 +00008037- Compiler now generates simpler and faster code for dictionary
8038 literals. The oparg for BUILD_MAP now indicates an estimated
8039 dictionary size. There is a new opcode, STORE_MAP, for adding
8040 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Patch #1739468: Directories and zipfiles containing a __main__.py
8070 file can now be directly executed by passing their name to the
8071 interpreter. The directory/zipfile is automatically inserted as the
8072 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008073
Georg Brandl3ee81df2008-05-17 18:14:43 +00008074- Issue #1265: Fix a problem with sys.settrace, if the tracing
8075 function uses a generator expression when at the same time the
8076 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008077
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008078- sets and frozensets now have an isdisjoint() method.
8079
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008080- optimize the performance of builtin.sum().
8081
Neal Norwitz44f326e2007-10-05 05:29:17 +00008082- Fix warnings found by the new version of the Coverity checker.
8083
Georg Brandl21e99f42010-03-07 15:23:59 +00008084- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8086 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008087
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- Issue #1686386: Tuple's tp_repr did not take into account the
8089 possibility of having a self-referential tuple, which is possible
8090 from C code. Nor did object's tp_str consider that a type's tp_str
8091 could do something that could lead to an inifinite recursion.
8092 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8093 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Issue #1164: It was possible to trigger deadlock when using the
8096 'print' statement to write to a file since the GIL was not released
8097 as needed. Now PyObject_Print() does the right thing along with
8098 various tp_print implementations of the built-in types and those in
8099 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008100
Georg Brandl3ee81df2008-05-17 18:14:43 +00008101- Issue #1147: Exceptions were directly allowing string exceptions in
8102 their throw() method even though string exceptions no longer
8103 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008104
Georg Brandl3ee81df2008-05-17 18:14:43 +00008105- Issue #1096: Prevent a segfault from getting the repr of a very
8106 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008107
Brett Cannon1e534b52007-09-07 04:18:30 +00008108- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008109 PyObject_Call() never calling back out to Python code to trigger
8110 recursion depth updates/checks. Required the creation of a static
8111 RuntimeError instance in case normalizing an exception put the
8112 recursion check value past its limit. Fixes crashers
8113 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008114

Neal Norwitz0ac60192007-05-27 04:08:54 +00008128- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008129 __*__ attributes. (Some already existed, e.g., __doc__ and
8130 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008131
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008132- Add -3 option to the interpreter to warn about features that are
8133 deprecated and will be changed/removed in Python 3.0.
8134
Georg Brandl2134e752007-05-21 20:34:16 +00008135- Patch #1686487: you can now pass any mapping after '**' in function
8136 calls.
8137
Collin Winter62903052007-05-18 23:11:24 +00008138- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139 "except E as target:". This is to provide forwards compatibility
8140 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008144- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008145 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008146
Vinay Sajip8549ce32007-05-06 17:53:37 +00008147- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008148 setting a plain string, ie don't expand to single letter identifiers.
8149
Raymond Hettinger13936692007-04-11 18:40:58 +00008150- Request #1191699: Slices can now be pickled.
8151
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008152- Request #1193128: str.translate() now allows a None argument for
8153 translations that only remove characters without re-mapping the
8154 remaining characters.
8155
Georg Brandl5cb76c12007-03-21 09:00:39 +00008156- Patch #1682205: a TypeError while unpacking an iterable is no longer

8160
Guido van Rossum143b5642007-03-23 04:58:42 +00008161- Bug #1683368: The object.__init__() and object.__new__() methods are
8162 now stricter in rejecting excess arguments. The only time when
8163 either allows excess arguments is when it is not overridden and the
8164 other one is. For backwards compatibility, when both are
8165 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008166 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00008169- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8170 object to complex using its __complex__() method before falling back
8171 to the __float__() method. Therefore, the functions in the cmath
8172 module now can operate on objects that define a __complex__()
8173 method.

8193
Georg Brandl871f1bc2007-03-12 13:17:36 +00008194- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008195 its argument, if it exists. If not, it will work like before. This
8196 allows customizing the output of dir() in the presence of a
8197 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00008209- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210 makes the filenames the warning module prints much more sensible
8211 when a PYTHONSTARTUP file is used.

8225 sq_ass_slice instead of the sq_slice slot.
8226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008279- Bug #1545497: when given an explicit base, int() did ignore NULs
8280 embedded in the string to convert.
8281
Georg Brandl846f73a2006-10-08 07:11:54 +00008282- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008312- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8313 Also make sure that every exception class has __module__ set to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008330 generator expressions (x for x, in ... ) works again. Fixing this
8331 problem required changing the .pyc magic number. This means that
8332 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009240 time so that opening a database previously created with the DB_DUP
9241 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9242 opens. Specifically: dictionary assignment to a DB object will
9243 replace all values for a given key when the database allows
9244 duplicate values. DB users should use DB.put(k, v) when they want
9245 to store duplicates; not DB[k] = v.

9252 characters with ASCII value less than 32. Also, it correctly quotes
9253 dots only if they occur on a single line, as opposed to the previous
9254 behavior of quoting dots if they are the second character of any
9255 line.
