Ned Deily18fae3f2013-01-31 01:24:55 -08001378- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1379 In particular, fix extension module build failures when trying to use
1380 32-bit-only installer Pythons on systems with Xcode 4 (currently
1381 OS X 10.8, 10.7, and optionally 10.6).
1382 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1383 * Since Xcode 4 removes ppc support, extension module builds now
1384 check for ppc compiler support and by default remove ppc and
1385 ppc64 archs when they are not available.
1386 * Extension module builds now revert to using system installed
1387 headers and libs (/usr and /System/Library) if the SDK used
1388 to build the interpreter is not installed or has moved.
1389 * Try to avoid building extension modules with deprecated
1390 and problematic Apple llvm-gcc compiler. If original compiler
1391 is not available, use clang instead by default.

1759 cleared by the garbage collector. This fixes a segfault when an instance
1760 and its type get caught in a reference cycle, and the instance's
1761 deallocator calls one of the methods on the type (e.g. when subclassing
1762 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01001815- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001816 has left two versions of customize_compiler, the original in
1817 distutils.sysconfig and another copy in distutils.ccompiler, with some
1818 parts of distutils calling one and others using the other.

1820 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001822- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1823 Distutils-based packages with C extension modules may fail because
1824 Apple has removed gcc-4.2, the version used to build python.org
1825 64-bit/32-bit Pythons. If the user does not explicitly override
1826 the default C compiler by setting the CC environment variable,
1827 Distutils will now attempt to compile extension modules with clang
1828 if gcc-4.2 is required but not found. Also as a convenience, if
1829 the user does explicitly set CC, substitute its value as the default
1830 compiler in the Distutils LDSHARED configuration variable for OS X.
1831 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1832 SDK, neither of which are available in Xcode 4. This change does not
1833 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002083- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2084 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2085 interpreter process. This could cause failures in non-Distutils subprocesses
2086 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002087 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002088 deployment target only in the environment of each build subprocess. It is
2089 still possible to globally override the default by setting
2090 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2091 greater or equal to the default value, the value with which the interpreter
2092 was built.

2121 updating the check interval, so if the user decreases the check interval,
2122 the ticker doesn't have to wind down to zero from the old starting point
2123 before the new interval takes effect. And if the user increases the
2124 interval, it makes sure the new limit takes effect right away rather have an
2125 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002950- Issue #9869: Make long() and PyNumber_Long return something of type
2951 long for a class whose __long__ method returns a plain int. This
2952 fixes an interpreter crash when initializing an instance of a long
2953 subclass from an object whose __long__ method returns a plain int.

2958 thread-local storage key.
2959
Victor Stinnercaafd772010-09-08 10:51:01 +00002960- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2961 encoding and errors attributes instead of using utf-8 in strict mode, to get
2962 the same behaviour than the print statement.
2963
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002964- Issue #9737: Fix a crash when trying to delete a slice or an item from

2978
2979 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2980 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

3095 by Andrew Bennetts.

3104
Raymond Hettinger20397532010-09-12 02:11:45 +00003105- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3106 This prevents user-created self-referencing ordered dictionaries from
3107 becoming permanently uncollectable GC garbage. The downside is that
3108 removing __del__ means that the internal doubly-linked list has to wait for
3109 GC collection rather than freeing memory immediately when the refcnt drops
3110 to zero.

3115
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003116- Issue #9792: In case of connection failure, socket.create_connection()
3117 would swallow the exception and raise a new one, making it impossible
3118 to fetch the original errno, or to filter timeout errors. Now the
3119 original error is re-raised.
3120
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003121- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3122 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3123 be updated back after the system call. Original patch by Brian Brazil.

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003131- Issue #808164: Fixed socket.close to avoid references to globals, to

3140
R. David Murray7c4bf552010-08-25 01:45:57 +00003141- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3142 character years even if the message contains RFC822 two character years.

3160
Benjamin Peterson52c36052010-08-21 03:03:22 +00003161- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3163
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003164- Issue #9626: the view methods for collections.OrderedDict() were returning

3170 without this marker will not be overwritten or removed.
3171
Antoine Pitroue1436d12010-08-12 15:25:51 +00003172- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3173 and a BadZipfile error is raised if it doesn't match (as used to be the
3174 case in Python 2.5 and earlier).
3175
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003176- Issue #9550: a BufferedReader could issue an additional read when the

3178 when the underlying raw IO channel was e.g. a socket. Report and original
3179 patch by Jason V. Miller.
3180
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003181- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003568- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3569 start byte and the continuation byte(s) are now considered invalid, instead
3570 of the number of bytes specified by the start byte.
3571 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3572 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3573 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3574 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003582- Issue #8748: Fix two issues with comparisons between complex and integer
3583 objects. (1) The comparison could incorrectly return True in some cases
3584 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3585 (2) The comparison raised an OverflowError for large integers, leading
3586 to unpredictable exceptions when combining integers and complex objects
3587 in sets or dicts.

3970 with a non-empty format string. This is an effort to future-proof user
3971 code. If a derived class does not currently implement __format__ but later
3972 adds its own __format__, it would most likely break user code that had

4026 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4027 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004029- Issue #2531: Comparison operations between floats and Decimal instances now
4030 return a result based on the numeric values of the operands; previously they
4031 returned an arbitrary result based on the relative ordering of id(float) and
4032 id(Decimal).

4047 Fractions instance now raise TypeError instead of returning True/False. This
4048 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4049 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004153- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4154 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00004156 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4157 inconsistent: __int__ was used for some integer codes but not for others, and
4158 the set of integer codes for which it was used differed between native packing
4159 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004467 file position when calling `truncate()`. It would previously change the file
4468 position to the given argument, which goes against the tradition of

4472 class used to represent files stored inside an archive. The new
4473 implementation is significantly faster and can be wrapped in a
4474 ``io.BufferedReader`` object for more speedups. It also solves an issue
4475 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Mark Dickinson1b34d252010-01-01 17:27:30 +00004572- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004573 DeprecationWarning when passed a float argument where an integer was expected.
4574 These functions and methods now raise TypeError instead. The majority of the
4575 effects of this change are in the extension modules, but some core functions
4576 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4577 and many unicode/str methods.

4742 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4743 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004744
Georg Brandlba83f822010-03-14 09:50:54 +00004745- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4746 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004748- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4749 1e-100 used to raise OverflowError, but now gives the requested 120
4750 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004758
Georg Brandlba83f822010-03-14 09:50:54 +00004759- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4760 decimal string that's guaranteed to round back to x under correct rounding
4761 (with round-half-to-even rounding mode). Previously it gave a string based on
4762 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4763 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4764 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004765
Georg Brandlba83f822010-03-14 09:50:54 +00004766- Issue #7117: On almost all platforms: float-to-string and string-to-float
4767 conversions within Python are now correctly rounded. Places these conversions
4768 occur include: str for floats and complex numbers; the float and complex
4769 constructors; old-style and new-style numeric formatting; serialization and
4770 deserialization of floats and complex numbers using marshal, pickle and json;
4771 parsing of float and imaginary literals in Python code; Decimal-to-float
4772 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004773
Georg Brandlba83f822010-03-14 09:50:54 +00004774 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4775 providing correctly-rounded strtod and dtoa C functions. This code is
4776 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4777 the C compiler. There may be a small number of platforms on which correct
4778 operation of this code cannot be guaranteed, so the code is not used: notably,
4779 this applies to platforms where the C double format is not IEEE 754 binary64,
4780 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4781 and Python's configure script is unable to determine how to change the FPU
4782 precision. On these platforms conversions use the platform strtod and dtoa,
4783 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004784
Georg Brandlba83f822010-03-14 09:50:54 +00004785- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4786 uses the correctly-rounded string <-> float conversions described above (when
4787 available), and so produces correctly rounded results that will display nicely
4788 under the float repr. There are two related small changes: (1) round now
4789 accepts any class with an ``__index__()`` method for its second argument (but
4790 no longer accepts floats for the second argument), and (2) an excessively
4791 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4792 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004934
Georg Brandlba83f822010-03-14 09:50:54 +00004935 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4936 (2) parsing of strings representing infinities and nans was locale aware; and
4937 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004939- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4940 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4941 but with at least one decimal point and with a default precision
4942 of 12. Previously, the behavior the same but with a default precision of 6.
4943 This more closely matches ``str()``, and reduces surprises when adding
4944 alignment flags to the empty presentation type. This also affects the new
4945 complex.__format__ in the same way.
4946
4947- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4948 classtype's, even if it was None. property now inserts the __doc__ into the
4949 subclass instance __dict__.

5019 internal representation of integers, for performance reasons. Base 2**30 is
5020 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00006434 leak-chasing test runs give sensible results. The previous method of reaping
6435 threads could return successfully while some Thread objects were still

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006557 AttributeError instead of RuntimeError, depending in which C API call
6558 exactly the recursion limit is exceeded. Consequently, both exception types
6559 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006576- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6577
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006578- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6579 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6580 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6581 ``printf`` function, whereas PyString_FromFormat has an independent
6582 implementation and uses "%zd" on all platforms for size_t values.
6583 This makes a difference on win64, where ``printf`` needs "%Id" to display
6584 64bit values.
6585
Benjamin Peterson97179b02008-09-09 20:55:01 +00006586- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6587 error.
6588
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006589- Issue #3777: long() applied to a float object now always return a long
6590 object; previously an int would be returned for small values. the __long__
6591 method is allowed to return either an int or a long, but the behaviour of
6592 float objects should not change to respect backward compatibility.
6593
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006594- Issue #3751: str.rpartition would perform a left-partition when called with
6595 a unicode argument.
6596
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006597- Issue #3683: Fix compilation when --without-threads is given.
6598
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006599- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006600 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006601 was correctly parsed but parsing of subsequent arguments failed.
6602
Vinay Sajip35e3b032008-09-01 14:33:59 +00006603- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006604 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6605 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6606 when given a tuple of classes as second argument, were looking up
6607 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6608 type object.
6609
Neal Norwitz18aa3882008-08-24 05:04:52 +00006610- Fix crashes on memory allocation failure found with failmalloc.
6611
6612- Fix memory leaks found with valgrind and update suppressions file.
6613
6614- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +00006618- Silenced another compiler warning about a used but not defined
6619 function 'stringlib_contains_obj'.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006679 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6680 for catch_warnings() also led to an improvement in the raising of a
6681 DeprecationWarning related to warnings.warn_explicit().
6682
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006683- The deprecation warnings for the old camelCase threading API were removed.

6752Core and Builtins
6753-----------------
6754
Guido van Rossumf8402962008-08-20 15:01:50 +00006755- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6756 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6757 extensions do not automatically benefit from the class attribute
6758 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6759 to their tp_flags field if they care. This is a backwards
6760 compatibility feature; in 3.0, all types will use the cache by
6761 default.
6762
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006763- Keyword arguments can now follow starred arguments. (``f(a, *args,
6764 keyword=23)`` is now valid syntax.)
6765
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006766- ctypes function pointers that are COM methods have a boolean True
6767 value again.
6768
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006769- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6770 by denying s# to parse objects that have a releasebuffer procedure,
6771 and introducing s*.
6772
Georg Brandl1e13ea92008-08-11 09:07:59 +00006773- Issue #3537: Fix an assertion failure when an empty but presized dict
6774 object was stored in the freelist.
6775
Mark Dickinsonb6467572008-08-04 21:30:09 +00006776- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6777 ValueError consistently across platforms.
6778
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006779- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6780 (64bit Unix, for example), unichr() would truncate its argument and return
6781 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6782
Neal Norwitze7d8be82008-07-31 17:17:14 +00006783- Apply security patches from Apple.
6784
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006785- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6786 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6787
Antoine Pitrou92f82162008-07-25 22:22:08 +00006788- Issue #1819: function calls with several named parameters are now on
6789 average 35% faster (as measured by pybench).
6790
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006791- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6792 the python debugger steps into a class statement: the free variables (local
6793 variables defined in an outer scope) would be deleted from the outer scope.
6794
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006795- Issue #2620: Overflow checking when allocating or reallocating memory
6796 was not always being done properly in some python types and extension
6797 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6798 all been updated to perform better checks and places in the code that
6799 would previously leak memory on the error path when such an allocation
6800 failed have been fixed.

6806
Benjamin Petersone977ad42008-08-20 01:42:01 +00006807- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6808 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6809
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006810- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6811 version reported by these tools does not necessarily follow the python
6812 version numbering scheme, so the module is less strict when parsing it.
6813
Nick Coghlanf70385a2008-08-18 12:42:46 +00006814- Issue #2235: Added Py3k warnings for types which will become unhashable
6815 under the stricter __hash__ inheritance rules in 3.0. Several types
6816 which did not meet the rules for hash invariants and were already
6817 unhashable in 3.0 have now been explicitly flagged as unhashable in
6818 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6819 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6820
Brett Cannon88f801d2008-08-18 00:46:22 +00006821- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6822 imported into the module but exposed as part of the module's API.
6823
Brett Cannon7b96f072008-08-18 00:41:11 +00006824- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006828- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6829
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006830- Issue #3575: Incremental decoder's decode function now takes bytearray
6831 by using 's*' instead of 't#'.
6832
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006833- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006834 fails unicode conversion on 2nd parameter. (windows only)

6934
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006935- Issue #643841: The language reference now provides more detailed

6948
Georg Brandl3e483f62008-07-16 22:57:41 +00006949- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6950 its methods now allow for items objects that can be converted to
6951 an integer using operator.index().
6952
Mark Dickinson64b7e502008-07-16 09:40:03 +00006953- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6954 produced a ValueError instead of giving the correct float.
6955
Eric Smitha5fa5a22008-07-16 00:11:49 +00006956- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6957 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6958
Mark Dickinson7103aa42008-07-15 19:08:33 +00006959- Issue #3008: the float type has a new instance method 'float.hex'
6960 and a new class method 'float.fromhex' to convert floating-point
6961 numbers to and from hexadecimal strings, respectively.
6962
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006963- Issue #2235: __hash__ is once again inherited by default. To allow
6964 collections.Hashable to remain meaningful in the presence of the
6965 default hash implementation (object.__hash__), it is now possible
6966 to explicit block inheritance of hash by setting __hash__=None at
6967 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6968 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00006970- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6971 the parent module cannot be found while performing an absolute import.
6972 This means that an incorrectly defined __package__ attribute will
6973 now only prevent relative imports in that module rather than causing
6974 all imports from that module to fail.
6975
Nick Coghlan14ff9942008-07-08 14:21:42 +00006976- Issue #2517: Allow unicode messages in Exceptions again by correctly

6986 another thread's dictionary.
6987
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006988- Issue #3004: Minor change to slice.indices(): the start and stop
6989 arguments are now treated identically, making the behaviour easier
6990 to describe and understand. For example, slice(None, -10,
6991 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6992 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6993 10, -1).

7036 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007037 wrong because the actual transmitted size could differ from the

7442
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007443- On MacOS X it is now possible to install the framework in 64-bit
7444 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007445 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007446
7447 This is controlled by the configure argument ``--with-universal-archs``:
7448
7449 - ``--with-universal-archs=all``: install 4-way universal
7450
7451 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7452
7453 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7454
7455 This option should be used in combination with ``--enable-universalsdk=``.
7456
7457 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 +00007506- Issue #1631171: Re-implement the 'warnings' module in C (the
7507 original Python code has been kept as backup). This will allow for
7508 using the 'warning's machinery in such places as the parser where
7509 use of pure Python code is not possible. Both the ``showarning()``
7510 and ``formatwarning()`` gain an optional 'line' argument which is
7511 not called by default for backwards-compatibility reasons. Setting
7512 ``warnings.showwarning()`` to an implementation that lacks support
7513 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007576- Issue #2550: The approach used by client/server code for obtaining
7577 ports to listen on in network-oriented tests has been refined in an
7578 effort to facilitate running multiple instances of the entire
7579 regression test suite in parallel without issue.
7580 test_support.bind_port() has been fixed such that it will always
7581 return a unique port -- which wasn't always the case with the
7582 previous implementation, especially if socket options had been set
7583 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7584 new implementation of bind_port() will actually raise an exception
7585 if it is passed an AF_INET/SOCK_STREAM socket with either the
7586 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7587 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7588 the socket it's been passed. This currently only applies to
7589 Windows. This option prevents any other sockets from binding to the
7590 host/port we've bound to, thus removing the possibility of the
7591 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7592 when a second SOCK_STREAM socket binds and accepts to a host/port
7593 that's already been bound by another socket. The optional preferred
7594 port parameter to bind_port() has been removed. Under no
7595 circumstances should tests be hard coding ports!
7596
7597 test_support.find_unused_port() has also been introduced, which will
7598 pass a temporary socket object to bind_port() in order to obtain an
7599 unused port. The temporary socket object is then closed and
7600 deleted, and the port is returned. This method should only be used
7601 for obtaining an unused port in order to pass to an external program
7602 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7603 a parameter to a server-oriented class that doesn't give you direct
7604 access to the underlying socket used.
7605
7606 Finally, test_support.HOST has been introduced, which should be used
7607 for the host argument of any relevant socket calls (i.e. bind and
7608 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007609
7610 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007611 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007612 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7613 test_asynchat and test_socket_ssl.
7614
Georg Brandl3ee81df2008-05-17 18:14:43 +00007615 It is now possible for multiple instances of the regression test
7616 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007895- Added the future_builtins module, which contains hex() and oct().
7896 These are the PEP 3127 version of these functions, designed to be
7897 compatible with the hex() and oct() builtins from Python 3.0. They
7898 differ slightly in their output formats from the existing, unchanged
7899 Python 2.6 builtins. The expected usage of the future_builtins
7900 module is:
7901 from future_builtins import hex, oct
7902
Eric Smith7ef40bf2008-02-20 23:34:22 +00007903- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7904 exponents for exponents with absolute value < 100. Follows C99
7905 standard. This is a change on Windows, which would use 3 digits.
7906 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7907 so that any alterations it does to the resulting string will be
7908 available in stringlib/formatter.h (for float.__format__).
7909
Eric Smith5a3c1352008-02-19 13:21:56 +00007910- Implemented PEP 3101, Advanced String Formatting. This adds a new
7911 builtin format(); a format() method for str and unicode; a
7912 __format__() method to object, str, unicode, int, long, float, and
7913 datetime; the class string.Formatter; and the C API
7914 PyObject_Format().
7915
Georg Brandl3ee81df2008-05-17 18:14:43 +00007916- Fixed several potential crashes, all caused by specially crafted
7917 __del__ methods exploiting objects in temporarily inconsistent
7918 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007920- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007921 prevent a possible crash: an Abstract Base Class would try to access
7922 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007927- Clear all free lists during a gc.collect() of the highest generation
7928 in order to allow pymalloc to free more arenas. Python may give back
7929 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Issue #2045: Fix an infinite recursion triggered when printing a
7932 subclass of collections.defaultdict, if its default_factory is set
7933 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007934
Christian Heimesf75dbef2008-02-08 00:11:31 +00007935- Fixed a minor memory leak in dictobject.c. The content of the free
7936 list was not freed on interpreter shutdown.
7937
Georg Brandl21e99f42010-03-07 15:23:59 +00007938- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007939 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007961- Patch #1473257: generator objects gain a gi_code attribute. This is
7962 the same object as the func_code attribute of the function that
7963 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007964
Georg Brandl3ee81df2008-05-17 18:14:43 +00007965- Issue #1920: "while 0" statements were completely removed by the
7966 compiler, even in the presence of an "else" clause, which is
7967 supposed to be run when the condition is false. Now the compiler
7968 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007969
Guido van Rossumeead05f2008-01-24 18:21:02 +00007970- A few crashers fixed: weakref_in_del.py (issue #1377858);
7971 loosing_dict_ref.py (issue #1303614, test67.py);
7972 borrowed_ref_[34].py (not in tracker).
7973
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007974- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007975 suppressed while an extension is loaded by calling SetErrorMode in
7976 dynload_win.c. The error is still reported properly.
7977
Georg Brandl3ee81df2008-05-17 18:14:43 +00007978- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007979 several extension methods and modules do not work without unicode
7980 support.
7981
Georg Brandl26543b12008-01-21 18:36:51 +00007982- Issue #1882: when compiling code from a string, encoding cookies in the

7986
Georg Brandl6caad7d2008-01-26 14:19:22 +00007987- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007988 added.
7989
Christian Heimesc94e2b52008-01-14 04:13:37 +00007990- sys.float_info / PyFloat_GetInfo: The floating point information
7991 object was converted from a dict to a specialized structseq object.
7992
Georg Brandl3ee81df2008-05-17 18:14:43 +00007993- Patch #1816: Added sys.flags structseq. It exposes the status of
7994 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007995
Georg Brandl3ee81df2008-05-17 18:14:43 +00007996- Objects/structseq.c: Implemented new structseq representation. The
7997 patch makes structseqs (e.g. the return value of os.stat) more
7998 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007999
Georg Brandl3ee81df2008-05-17 18:14:43 +00008000- Patch #1700288: added a type attribute cache that caches method
8001 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008002
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008003- Bug #1776: __import__() no longer accepts filenames on any platform.
8004 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008005
Georg Brandlaed6c662008-01-07 17:25:53 +00008006- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8007
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8009 envvar and sys.dont_write_bytecode attribute. All these can be set
8010 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008011
Georg Brandl3ee81df2008-05-17 18:14:43 +00008012- Improve some exception messages when Windows fails to load an
8013 extension module. Now we get for example '%1 is not a valid Win32
8014 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008015

Christian Heimes0a8143f2007-12-18 23:22:54 +00008021- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022 and INF. float("nan"), float("inf") and float("-inf") now work on
8023 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008024
Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Compiler now generates simpler and faster code for dictionary
8026 literals. The oparg for BUILD_MAP now indicates an estimated
8027 dictionary size. There is a new opcode, STORE_MAP, for adding
8028 entries to the dictionary.

8058 file can now be directly executed by passing their name to the
8059 interpreter. The directory/zipfile is automatically inserted as the
8060 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008062- Issue #1265: Fix a problem with sys.settrace, if the tracing
8063 function uses a generator expression when at the same time the
8064 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008065
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008066- sets and frozensets now have an isdisjoint() method.
8067
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008068- optimize the performance of builtin.sum().
8069

8071
Georg Brandl21e99f42010-03-07 15:23:59 +00008072- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008073 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8074 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008075
Georg Brandl3ee81df2008-05-17 18:14:43 +00008076- Issue #1686386: Tuple's tp_repr did not take into account the
8077 possibility of having a self-referential tuple, which is possible
8078 from C code. Nor did object's tp_str consider that a type's tp_str
8079 could do something that could lead to an inifinite recursion.
8080 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8081 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008082
Georg Brandl3ee81df2008-05-17 18:14:43 +00008083- Issue #1164: It was possible to trigger deadlock when using the
8084 'print' statement to write to a file since the GIL was not released
8085 as needed. Now PyObject_Print() does the right thing along with
8086 various tp_print implementations of the built-in types and those in
8087 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008088
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089- Issue #1147: Exceptions were directly allowing string exceptions in

8091 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008092
Georg Brandl3ee81df2008-05-17 18:14:43 +00008093- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00008095
Brett Cannon1e534b52007-09-07 04:18:30 +00008096- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008097 PyObject_Call() never calling back out to Python code to trigger
8098 recursion depth updates/checks. Required the creation of a static
8099 RuntimeError instance in case normalizing an exception put the
8100 recursion check value past its limit. Fixes crashers
8101 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008102

Neal Norwitz0ac60192007-05-27 04:08:54 +00008116- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008117 __*__ attributes. (Some already existed, e.g., __doc__ and
8118 __name__.)

8122
Georg Brandl2134e752007-05-21 20:34:16 +00008123- Patch #1686487: you can now pass any mapping after '**' in function
8124 calls.
8125
Collin Winter62903052007-05-18 23:11:24 +00008126- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008127 "except E as target:". This is to provide forwards compatibility
8128 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00008130- Deprecate BaseException.message as per PEP 352.
8131
Georg Brandl3ee81df2008-05-17 18:14:43 +00008132- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008133 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008135- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008136 setting a plain string, ie don't expand to single letter identifiers.
8137
Raymond Hettinger13936692007-04-11 18:40:58 +00008138- Request #1191699: Slices can now be pickled.
8139
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008140- Request #1193128: str.translate() now allows a None argument for
8141 translations that only remove characters without re-mapping the
8142 remaining characters.
8143
Georg Brandl5cb76c12007-03-21 09:00:39 +00008144- Patch #1682205: a TypeError while unpacking an iterable is no longer
8145 masked by a generic one with the message "unpack non-sequence".
8146
Neal Norwitzaa754b72007-03-21 06:39:48 +00008147- Remove unused file Python/fmod.c.
8148
Guido van Rossum143b5642007-03-23 04:58:42 +00008149- Bug #1683368: The object.__init__() and object.__new__() methods are
8150 now stricter in rejecting excess arguments. The only time when
8151 either allows excess arguments is when it is not overridden and the
8152 other one is. For backwards compatibility, when both are
8153 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008154 warning later). Also, type.__init__() insists on the same signature
8155 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008156
Georg Brandl3ee81df2008-05-17 18:14:43 +00008157- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8158 object to complex using its __complex__() method before falling back
8159 to the __float__() method. Therefore, the functions in the cmath

Georg Brandlaa2321b2007-03-07 00:40:28 +00008197- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00008267- Bug #1545497: when given an explicit base, int() did ignore NULs
8268 embedded in the string to convert.
8269
Georg Brandl846f73a2006-10-08 07:11:54 +00008270- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008300- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008318 generator expressions (x for x, in ... ) works again. Fixing this
8319 problem required changing the .pyc magic number. This means that

9210 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9211 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009228 time so that opening a database previously created with the DB_DUP
9229 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9230 opens. Specifically: dictionary assignment to a DB object will
9231 replace all values for a given key when the database allows
9232 duplicate values. DB users should use DB.put(k, v) when they want
9233 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009234

9240 characters with ASCII value less than 32. Also, it correctly quotes
9241 dots only if they occur on a single line, as opposed to the previous
9242 behavior of quoting dots if they are the second character of any
9243 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009244
