40 warnings. Patch by Josh Triplett and Petri Lehtinen.
41
Mark Hammond323b5da2011-10-17 11:05:36 +110042- Issue #7833: Extension modules built using distutils on Windows will no
43 longer include a "manifest" to prevent them failing at import time in some
44 embedded situations.
45

Mark Dickinsondbbed042011-09-19 16:38:08 +010055- Issue #12973: Fix overflow checks that invoked undefined behaviour in
56 int.__pow__. These overflow checks were causing int.__pow__ to produce
57 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010058 compiler optimizing the check away. Also fix similar overflow checks
59 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
60 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010061
Ezio Melotti15d6b652011-08-15 09:22:24 +030062- Issue #12266: Fix str.capitalize() to correctly uppercase/lowercase

72 cleared by the garbage collector. This fixes a segfault when an instance
73 and its type get caught in a reference cycle, and the instance's
74 deallocator calls one of the methods on the type (e.g. when subclassing
75 IOBase). Diagnosis and patch by Davide Rizzo.
76

Victor Stinner08563d92011-05-30 23:44:13 +020084 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
85 raw_input() interrupted by CTRL+c.
86
Łukasz Langa7a153902011-10-18 17:16:00 +020087- Issue #10860: httplib now correctly handles an empty port after port
88 delimiter in URLs.
89

Florent Xiclunac2279652012-02-12 14:49:03 +0100118- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100119 has left two versions of customize_compiler, the original in
120 distutils.sysconfig and another copy in distutils.ccompiler, with some
121 parts of distutils calling one and others using the other.
122 Complete the revert back to only having one in distutils.sysconfig as
123 is the case in 3.x.
124
Ned Deily0d0ea482012-02-10 12:59:06 +0100125- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
126 Distutils-based packages with C extension modules may fail because
127 Apple has removed gcc-4.2, the version used to build python.org
128 64-bit/32-bit Pythons. If the user does not explicitly override
129 the default C compiler by setting the CC environment variable,
130 Distutils will now attempt to compile extension modules with clang
131 if gcc-4.2 is required but not found. Also as a convenience, if
132 the user does explicitly set CC, substitute its value as the default
133 compiler in the Distutils LDSHARED configuration variable for OS X.
134 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
135 SDK, neither of which are available in Xcode 4. This change does not
136 attempt to override settings to support their use with Xcode 4.)
137

Senthil Kumaran607e31e2012-02-09 17:43:31 +0800140- Issue #6005: Examples in the socket library documentation use sendall, where
141 relevant, instead send method.
142
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200143- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
144 raise a ProgrammingError now.
145
Ned Deily2c8bf042012-02-06 00:55:50 +0100146- Issue #10881: Fix test_site failures with OS X framework builds.

224 Patch by sbt.
225

Ned Deily87e82bb2011-06-28 19:52:59 -0700411- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
412 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
413 interpreter process. This could cause failures in non-Distutils subprocesses
414 and was unreliable since tests or user programs could modify the interpreter
415 environment after Distutils set it. Instead, have Distutils set the the
416 deployment target only in the environment of each build subprocess. It is
417 still possible to globally override the default by setting
418 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
419 greater or equal to the default value, the value with which the interpreter
420 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400448- sys.setcheckinterval() now updates the current ticker count as well as
449 updating the check interval, so if the user decreases the check interval,
450 the ticker doesn't have to wind down to zero from the old starting point
451 before the new interval takes effect. And if the user increases the
452 interval, it makes sure the new limit takes effect right away rather have an
453 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001227- Issue #9869: Make long() and PyNumber_Long return something of type
1228 long for a class whose __long__ method returns a plain int. This
1229 fixes an interpreter crash when initializing an instance of a long
1230 subclass from an object whose __long__ method returns a plain int.

1235 thread-local storage key.
1236
Victor Stinnercaafd772010-09-08 10:51:01 +00001237- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1238 encoding and errors attributes instead of using utf-8 in strict mode, to get
1239 the same behaviour than the print statement.

1381
Raymond Hettinger20397532010-09-12 02:11:45 +00001382- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1383 This prevents user-created self-referencing ordered dictionaries from
1384 becoming permanently uncollectable GC garbage. The downside is that
1385 removing __del__ means that the internal doubly-linked list has to wait for
1386 GC collection rather than freeing memory immediately when the refcnt drops
1387 to zero.
1388

1392
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001393- Issue #9792: In case of connection failure, socket.create_connection()
1394 would swallow the exception and raise a new one, making it impossible
1395 to fetch the original errno, or to filter timeout errors. Now the
1396 original error is re-raised.
1397

1400 be updated back after the system call. Original patch by Brian Brazil.

R. David Murray7c4bf552010-08-25 01:45:57 +00001418- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001846- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1847 start byte and the continuation byte(s) are now considered invalid, instead
1848 of the number of bytes specified by the start byte.
1849 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1850 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1862 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2248 with a non-empty format string. This is an effort to future-proof user
2249 code. If a derived class does not currently implement __format__ but later
2250 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002251 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002252 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002744- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002745 file position when calling `truncate()`. It would previously change the file
2746 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002747 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00002749- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2750 class used to represent files stored inside an archive. The new
2751 implementation is significantly faster and can be wrapped in a
2752 ``io.BufferedReader`` object for more speedups. It also solves an issue
2753 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2843
Georg Brandlba83f822010-03-14 09:50:54 +00002844- The ``__complex__()`` method is now looked up on the class of instances to
2845 make it consistent with other special methods.

2849
Mark Dickinson1b34d252010-01-01 17:27:30 +00002850- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002851 DeprecationWarning when passed a float argument where an integer was expected.
2852 These functions and methods now raise TypeError instead. The majority of the
2853 effects of this change are in the extension modules, but some core functions
2854 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2855 and many unicode/str methods.

2870 least on IEEE 754 platforms), and in particular does not depend on the
2871 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003020- Issue #3382: 'F' formatting for float and complex now convert the result to
3021 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3022 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003023
Georg Brandlba83f822010-03-14 09:50:54 +00003024- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3025 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003026
Georg Brandlba83f822010-03-14 09:50:54 +00003027- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3028 1e-100 used to raise OverflowError, but now gives the requested 120
3029 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003037
Georg Brandlba83f822010-03-14 09:50:54 +00003038- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3039 decimal string that's guaranteed to round back to x under correct rounding
3040 (with round-half-to-even rounding mode). Previously it gave a string based on
3041 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3042 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3043 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003044
Georg Brandlba83f822010-03-14 09:50:54 +00003045- Issue #7117: On almost all platforms: float-to-string and string-to-float
3046 conversions within Python are now correctly rounded. Places these conversions
3047 occur include: str for floats and complex numbers; the float and complex
3048 constructors; old-style and new-style numeric formatting; serialization and
3049 deserialization of floats and complex numbers using marshal, pickle and json;
3050 parsing of float and imaginary literals in Python code; Decimal-to-float
3051 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003052
Georg Brandlba83f822010-03-14 09:50:54 +00003053 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3054 providing correctly-rounded strtod and dtoa C functions. This code is
3055 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3056 the C compiler. There may be a small number of platforms on which correct
3057 operation of this code cannot be guaranteed, so the code is not used: notably,
3058 this applies to platforms where the C double format is not IEEE 754 binary64,
3059 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3060 and Python's configure script is unable to determine how to change the FPU
3061 precision. On these platforms conversions use the platform strtod and dtoa,
3062 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003063
Georg Brandlba83f822010-03-14 09:50:54 +00003064- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3065 uses the correctly-rounded string <-> float conversions described above (when
3066 available), and so produces correctly rounded results that will display nicely
3067 under the float repr. There are two related small changes: (1) round now
3068 accepts any class with an ``__index__()`` method for its second argument (but
3069 no longer accepts floats for the second argument), and (2) an excessively
3070 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3071 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003212- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003213
Georg Brandlba83f822010-03-14 09:50:54 +00003214 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3215 (2) parsing of strings representing infinities and nans was locale aware; and
3216 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003218- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3219 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3220 but with at least one decimal point and with a default precision
3221 of 12. Previously, the behavior the same but with a default precision of 6.
3222 This more closely matches ``str()``, and reduces surprises when adding
3223 alignment flags to the empty presentation type. This also affects the new
3224 complex.__format__ in the same way.
3225
3226- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004710 leak-chasing test runs give sensible results. The previous method of reaping
4711 threads could return successfully while some Thread objects were still
4712 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00004832- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004833 AttributeError instead of RuntimeError, depending in which C API call
4834 exactly the recursion limit is exceeded. Consequently, both exception types
4835 are caught and silenced.

4851
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004852- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4853
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004854- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4855 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4856 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4857 ``printf`` function, whereas PyString_FromFormat has an independent
4858 implementation and uses "%zd" on all platforms for size_t values.
4859 This makes a difference on win64, where ``printf`` needs "%Id" to display
4860 64bit values.
4861
Benjamin Peterson97179b02008-09-09 20:55:01 +00004862- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4863 error.
4864
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004865- Issue #3777: long() applied to a float object now always return a long
4866 object; previously an int would be returned for small values. the __long__
4867 method is allowed to return either an int or a long, but the behaviour of
4868 float objects should not change to respect backward compatibility.
4869
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004870- Issue #3751: str.rpartition would perform a left-partition when called with
4871 a unicode argument.
4872
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004873- Issue #3683: Fix compilation when --without-threads is given.
4874
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004875- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004876 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004877 was correctly parsed but parsing of subsequent arguments failed.
4878
Vinay Sajip35e3b032008-09-01 14:33:59 +00004879- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004880 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4881 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4882 when given a tuple of classes as second argument, were looking up
4883 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4884 type object.
4885
Neal Norwitz18aa3882008-08-24 05:04:52 +00004886- Fix crashes on memory allocation failure found with failmalloc.
4887
4888- Fix memory leaks found with valgrind and update suppressions file.
4889
4890- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4891
4892- Fix problem using wrong name in decimal module reported by pychecker.
4893
Christian Heimes7d4c3172008-08-22 19:47:25 +00004894- Silenced another compiler warning about a used but not defined
4895 function 'stringlib_contains_obj'.

4898 ``__delslice__``.
4899
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004900- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4901 library targets in the Makefile.
4902
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004903- Issue #1204: The configure script now tests for additional libraries
4904 that may be required when linking against readline. This fixes issues
4905 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

4916 stack usage in the case of deeply nested objects.
4917

Brett Cannon672237d2008-09-09 00:49:16 +00004929 return a list or None rather than a custom object.
4930
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004931- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004955 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4956 for catch_warnings() also led to an improvement in the raising of a
4957 DeprecationWarning related to warnings.warn_explicit().
4958
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004959- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004982- Issue #2975: When compiling several extension modules with Visual Studio 2008
4983 from the same python interpreter, some environment variables would grow
4984 without limit.
4985
Benjamin Peterson37346b22008-08-23 20:27:43 +00004986- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5028Core and Builtins
5029-----------------
5030
Guido van Rossumf8402962008-08-20 15:01:50 +00005031- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5032 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5033 extensions do not automatically benefit from the class attribute
5034 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5035 to their tp_flags field if they care. This is a backwards
5036 compatibility feature; in 3.0, all types will use the cache by
5037 default.
5038
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005039- Keyword arguments can now follow starred arguments. (``f(a, *args,
5040 keyword=23)`` is now valid syntax.)
5041
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005042- ctypes function pointers that are COM methods have a boolean True
5043 value again.
5044
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005045- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5046 by denying s# to parse objects that have a releasebuffer procedure,
5047 and introducing s*.
5048
Georg Brandl1e13ea92008-08-11 09:07:59 +00005049- Issue #3537: Fix an assertion failure when an empty but presized dict
5050 object was stored in the freelist.
5051
Mark Dickinsonb6467572008-08-04 21:30:09 +00005052- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5053 ValueError consistently across platforms.
5054
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005055- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5056 (64bit Unix, for example), unichr() would truncate its argument and return
5057 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5058
Neal Norwitze7d8be82008-07-31 17:17:14 +00005059- Apply security patches from Apple.
5060
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005061- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5062 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5063
Antoine Pitrou92f82162008-07-25 22:22:08 +00005064- Issue #1819: function calls with several named parameters are now on
5065 average 35% faster (as measured by pybench).
5066
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005067- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5068 the python debugger steps into a class statement: the free variables (local
5069 variables defined in an outer scope) would be deleted from the outer scope.
5070
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005071- Issue #2620: Overflow checking when allocating or reallocating memory
5072 was not always being done properly in some python types and extension
5073 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5074 all been updated to perform better checks and places in the code that
5075 would previously leak memory on the error path when such an allocation
5076 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005081- Issue #3612: Added some missing basic types in ctypes.wintypes.
5082
Benjamin Petersone977ad42008-08-20 01:42:01 +00005083- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5084 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5085
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005086- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5087 version reported by these tools does not necessarily follow the python
5088 version numbering scheme, so the module is less strict when parsing it.
5089
Nick Coghlanf70385a2008-08-18 12:42:46 +00005090- Issue #2235: Added Py3k warnings for types which will become unhashable
5091 under the stricter __hash__ inheritance rules in 3.0. Several types
5092 which did not meet the rules for hash invariants and were already
5093 unhashable in 3.0 have now been explicitly flagged as unhashable in
5094 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5095 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5096
Brett Cannon88f801d2008-08-18 00:46:22 +00005097- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5098 imported into the module but exposed as part of the module's API.
5099
Brett Cannon7b96f072008-08-18 00:41:11 +00005100- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5101
Brett Cannon46225e72008-08-18 00:36:52 +00005102- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005104- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5105
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005106- Issue #3575: Incremental decoder's decode function now takes bytearray
5107 by using 's*' instead of 't#'.

5210
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005211- Issue #643841: The language reference now provides more detailed

5223-----------------
5224
Georg Brandl3e483f62008-07-16 22:57:41 +00005225- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5226 its methods now allow for items objects that can be converted to
5227 an integer using operator.index().
5228
Mark Dickinson64b7e502008-07-16 09:40:03 +00005229- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5230 produced a ValueError instead of giving the correct float.
5231
Eric Smitha5fa5a22008-07-16 00:11:49 +00005232- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5233 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5234
Mark Dickinson7103aa42008-07-15 19:08:33 +00005235- Issue #3008: the float type has a new instance method 'float.hex'
5236 and a new class method 'float.fromhex' to convert floating-point
5237 numbers to and from hexadecimal strings, respectively.
5238
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005239- Issue #2235: __hash__ is once again inherited by default. To allow
5240 collections.Hashable to remain meaningful in the presence of the
5241 default hash implementation (object.__hash__), it is now possible
5242 to explicit block inheritance of hash by setting __hash__=None at
5243 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5244 level.
5245
Nick Coghlanb028f502008-07-13 14:52:36 +00005246- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5247 the parent module cannot be found while performing an absolute import.
5248 This means that an incorrectly defined __package__ attribute will
5249 now only prevent relative imports in that module rather than causing
5250 all imports from that module to fail.
5251
Nick Coghlan14ff9942008-07-08 14:21:42 +00005252- Issue #2517: Allow unicode messages in Exceptions again by correctly

5262 another thread's dictionary.
5263
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005264- Issue #3004: Minor change to slice.indices(): the start and stop
5265 arguments are now treated identically, making the behaviour easier
5266 to describe and understand. For example, slice(None, -10,
5267 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5268 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5269 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00005271- Issue #3219: Calling a function with repeated keyword arguments,
5272 f(a=2, a=23), would not cause a syntax error. This was a regression
5273 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005275- Issue #2862: Make int and float freelist management consistent with
5276 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005311- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5312 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005313 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005314 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005330- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5674 suitable sign) if n is large and negative; previously, it raised
5675 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005721- On MacOS X it is now possible to install the framework in 64-bit
5722 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005723 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005724
5725 This is controlled by the configure argument ``--with-universal-archs``:
5726
5727 - ``--with-universal-archs=all``: install 4-way universal
5728
5729 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5730
5731 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5732
5733 This option should be used in combination with ``--enable-universalsdk=``.
5734
5735 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 +00005785- Issue #1631171: Re-implement the 'warnings' module in C (the
5786 original Python code has been kept as backup). This will allow for
5787 using the 'warning's machinery in such places as the parser where
5788 use of pure Python code is not possible. Both the ``showarning()``
5789 and ``formatwarning()`` gain an optional 'line' argument which is
5790 not called by default for backwards-compatibility reasons. Setting
5791 ``warnings.showwarning()`` to an implementation that lacks support
5792 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005855- Issue #2550: The approach used by client/server code for obtaining
5856 ports to listen on in network-oriented tests has been refined in an
5857 effort to facilitate running multiple instances of the entire
5858 regression test suite in parallel without issue.
5859 test_support.bind_port() has been fixed such that it will always
5860 return a unique port -- which wasn't always the case with the
5861 previous implementation, especially if socket options had been set
5862 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5863 new implementation of bind_port() will actually raise an exception
5864 if it is passed an AF_INET/SOCK_STREAM socket with either the
5865 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5866 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5867 the socket it's been passed. This currently only applies to
5868 Windows. This option prevents any other sockets from binding to the
5869 host/port we've bound to, thus removing the possibility of the
5870 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5871 when a second SOCK_STREAM socket binds and accepts to a host/port
5872 that's already been bound by another socket. The optional preferred
5873 port parameter to bind_port() has been removed. Under no
5874 circumstances should tests be hard coding ports!
5875
5876 test_support.find_unused_port() has also been introduced, which will
5877 pass a temporary socket object to bind_port() in order to obtain an
5878 unused port. The temporary socket object is then closed and
5879 deleted, and the port is returned. This method should only be used
5880 for obtaining an unused port in order to pass to an external program
5881 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5882 a parameter to a server-oriented class that doesn't give you direct
5883 access to the underlying socket used.
5884
5885 Finally, test_support.HOST has been introduced, which should be used
5886 for the host argument of any relevant socket calls (i.e. bind and
5887 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005888
5889 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005890 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005891 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5892 test_asynchat and test_socket_ssl.
5893
Georg Brandl3ee81df2008-05-17 18:14:43 +00005894 It is now possible for multiple instances of the regression test
5895 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005949- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5951 Plane. This affected raw unicode literals and the
5952 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5953 this case, like normal unicode literals and the 'unicode-escape'
5954 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006174- Added the future_builtins module, which contains hex() and oct().
6175 These are the PEP 3127 version of these functions, designed to be
6176 compatible with the hex() and oct() builtins from Python 3.0. They
6177 differ slightly in their output formats from the existing, unchanged
6178 Python 2.6 builtins. The expected usage of the future_builtins
6179 module is:
6180 from future_builtins import hex, oct
6181
Eric Smith7ef40bf2008-02-20 23:34:22 +00006182- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6183 exponents for exponents with absolute value < 100. Follows C99
6184 standard. This is a change on Windows, which would use 3 digits.
6185 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6186 so that any alterations it does to the resulting string will be
6187 available in stringlib/formatter.h (for float.__format__).
6188
Eric Smith5a3c1352008-02-19 13:21:56 +00006189- Implemented PEP 3101, Advanced String Formatting. This adds a new
6190 builtin format(); a format() method for str and unicode; a
6191 __format__() method to object, str, unicode, int, long, float, and
6192 datetime; the class string.Formatter; and the C API
6193 PyObject_Format().
6194
Georg Brandl3ee81df2008-05-17 18:14:43 +00006195- Fixed several potential crashes, all caused by specially crafted
6196 __del__ methods exploiting objects in temporarily inconsistent
6197 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006198
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006199- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200 prevent a possible crash: an Abstract Base Class would try to access
6201 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006202

Georg Brandl3ee81df2008-05-17 18:14:43 +00006206- Clear all free lists during a gc.collect() of the highest generation
6207 in order to allow pymalloc to free more arenas. Python may give back
6208 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006209
Georg Brandl3ee81df2008-05-17 18:14:43 +00006210- Issue #2045: Fix an infinite recursion triggered when printing a
6211 subclass of collections.defaultdict, if its default_factory is set
6212 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006213
Christian Heimesf75dbef2008-02-08 00:11:31 +00006214- Fixed a minor memory leak in dictobject.c. The content of the free
6215 list was not freed on interpreter shutdown.
6216
Georg Brandl21e99f42010-03-07 15:23:59 +00006217- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006218 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006219
Georg Brandl3ee81df2008-05-17 18:14:43 +00006220- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6221 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006222 to compact the internal free lists of pre-allocted ints and floats.
6223
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6225 calls. Python expected the return type int but the fork familie
6226 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006240- Patch #1473257: generator objects gain a gi_code attribute. This is
6241 the same object as the func_code attribute of the function that
6242 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006243
Georg Brandl3ee81df2008-05-17 18:14:43 +00006244- Issue #1920: "while 0" statements were completely removed by the
6245 compiler, even in the presence of an "else" clause, which is
6246 supposed to be run when the condition is false. Now the compiler
6247 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006248
Guido van Rossumeead05f2008-01-24 18:21:02 +00006249- A few crashers fixed: weakref_in_del.py (issue #1377858);
6250 loosing_dict_ref.py (issue #1303614, test67.py);
6251 borrowed_ref_[34].py (not in tracker).
6252
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006253- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006254 suppressed while an extension is loaded by calling SetErrorMode in
6255 dynload_win.c. The error is still reported properly.
6256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006258 several extension methods and modules do not work without unicode
6259 support.
6260
Georg Brandl26543b12008-01-21 18:36:51 +00006261- Issue #1882: when compiling code from a string, encoding cookies in the

6265
Georg Brandl6caad7d2008-01-26 14:19:22 +00006266- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006267 added.
6268
Christian Heimesc94e2b52008-01-14 04:13:37 +00006269- sys.float_info / PyFloat_GetInfo: The floating point information
6270 object was converted from a dict to a specialized structseq object.
6271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Patch #1816: Added sys.flags structseq. It exposes the status of
6273 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Objects/structseq.c: Implemented new structseq representation. The
6276 patch makes structseqs (e.g. the return value of os.stat) more
6277 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006278
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Patch #1700288: added a type attribute cache that caches method
6280 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006281
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006282- Bug #1776: __import__() no longer accepts filenames on any platform.
6283 The first parameter to __import__() must be a valid module name.

6288 envvar and sys.dont_write_bytecode attribute. All these can be set
6289 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006290
Georg Brandl3ee81df2008-05-17 18:14:43 +00006291- Improve some exception messages when Windows fails to load an
6292 extension module. Now we get for example '%1 is not a valid Win32
6293 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006294

Christian Heimes0a8143f2007-12-18 23:22:54 +00006300- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006301 and INF. float("nan"), float("inf") and float("-inf") now work on
6302 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006303
Georg Brandl3ee81df2008-05-17 18:14:43 +00006304- Compiler now generates simpler and faster code for dictionary
6305 literals. The oparg for BUILD_MAP now indicates an estimated
6306 dictionary size. There is a new opcode, STORE_MAP, for adding
6307 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006336- Patch #1739468: Directories and zipfiles containing a __main__.py
6337 file can now be directly executed by passing their name to the
6338 interpreter. The directory/zipfile is automatically inserted as the
6339 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006340
Georg Brandl3ee81df2008-05-17 18:14:43 +00006341- Issue #1265: Fix a problem with sys.settrace, if the tracing
6342 function uses a generator expression when at the same time the
6343 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006344
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006345- sets and frozensets now have an isdisjoint() method.
6346
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006347- optimize the performance of builtin.sum().

6350
Georg Brandl21e99f42010-03-07 15:23:59 +00006351- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006352 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6353 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006354
Georg Brandl3ee81df2008-05-17 18:14:43 +00006355- Issue #1686386: Tuple's tp_repr did not take into account the
6356 possibility of having a self-referential tuple, which is possible
6357 from C code. Nor did object's tp_str consider that a type's tp_str
6358 could do something that could lead to an inifinite recursion.
6359 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6360 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006361
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Issue #1164: It was possible to trigger deadlock when using the
6363 'print' statement to write to a file since the GIL was not released
6364 as needed. Now PyObject_Print() does the right thing along with
6365 various tp_print implementations of the built-in types and those in
6366 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006367
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368- Issue #1147: Exceptions were directly allowing string exceptions in
6369 their throw() method even though string exceptions no longer
6370 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006371
Georg Brandl3ee81df2008-05-17 18:14:43 +00006372- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00006374
Brett Cannon1e534b52007-09-07 04:18:30 +00006375- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006376 PyObject_Call() never calling back out to Python code to trigger
6377 recursion depth updates/checks. Required the creation of a static
6378 RuntimeError instance in case normalizing an exception put the
6379 recursion check value past its limit. Fixes crashers
6380 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006381

Neal Norwitz0ac60192007-05-27 04:08:54 +00006395- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006396 __*__ attributes. (Some already existed, e.g., __doc__ and
6397 __name__.)

6401
Georg Brandl2134e752007-05-21 20:34:16 +00006402- Patch #1686487: you can now pass any mapping after '**' in function
6403 calls.
6404
Collin Winter62903052007-05-18 23:11:24 +00006405- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406 "except E as target:". This is to provide forwards compatibility
6407 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006411- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006412 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006413
Vinay Sajip8549ce32007-05-06 17:53:37 +00006414- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006415 setting a plain string, ie don't expand to single letter identifiers.
6416
Raymond Hettinger13936692007-04-11 18:40:58 +00006417- Request #1191699: Slices can now be pickled.
6418
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006419- Request #1193128: str.translate() now allows a None argument for
6420 translations that only remove characters without re-mapping the
6421 remaining characters.
6422
Georg Brandl5cb76c12007-03-21 09:00:39 +00006423- Patch #1682205: a TypeError while unpacking an iterable is no longer

6427
Guido van Rossum143b5642007-03-23 04:58:42 +00006428- Bug #1683368: The object.__init__() and object.__new__() methods are
6429 now stricter in rejecting excess arguments. The only time when
6430 either allows excess arguments is when it is not overridden and the
6431 other one is. For backwards compatibility, when both are
6432 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006433 warning later). Also, type.__init__() insists on the same signature
6434 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006436- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6437 object to complex using its __complex__() method before falling back
6438 to the __float__() method. Therefore, the functions in the cmath
6439 module now can operate on objects that define a __complex__()
6440 method.

6460
Georg Brandl871f1bc2007-03-12 13:17:36 +00006461- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006462 its argument, if it exists. If not, it will work like before. This
6463 allows customizing the output of dir() in the presence of a
6464 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006476- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006477 makes the filenames the warning module prints much more sensible
6478 when a PYTHONSTARTUP file is used.

6492 sq_ass_slice instead of the sq_slice slot.
6493
Georg Brandl3ee81df2008-05-17 18:14:43 +00006494- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006546- Bug #1545497: when given an explicit base, int() did ignore NULs
6547 embedded in the string to convert.
6548
Georg Brandl846f73a2006-10-08 07:11:54 +00006549- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006597 generator expressions (x for x, in ... ) works again. Fixing this
6598 problem required changing the .pyc magic number. This means that
6599 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007402- The implementation of UnicodeError objects has been simplified
7403 (start and end attributes are now stored directly as Py_ssize_t
7404 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007405
Georg Brandl3ee81df2008-05-17 18:14:43 +00007406- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7407 with RFC 3207 and forgets any knowledge obtained from the server not
7408 obtained from the TLS negotiation itself. Patch contributed by Bill
7409 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007412 that the SMTP.starttls() caller no longer needs to call ehlo()
7413 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007414 does not claim to support starttls. Adds the
7415 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7416 Fenner.

7486 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007487
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488- Added wide char functions to msvcrt module: getwch, getwche, putwch

7496 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7497 silently miscode subclasses of those types. Now, it raises a
7498 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007499

Georg Brandl3ee81df2008-05-17 18:14:43 +00007514 time so that opening a database previously created with the DB_DUP
7515 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7516 opens. Specifically: dictionary assignment to a DB object will
7517 replace all values for a given key when the database allows
7518 duplicate values. DB users should use DB.put(k, v) when they want
7519 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007520

7526 characters with ASCII value less than 32. Also, it correctly quotes
7527 dots only if they occur on a single line, as opposed to the previous
7528 behavior of quoting dots if they are the second character of any
7529 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007530
