9Core and Builtins
10-----------------
11
Serhiy Storchaka98a97222014-02-09 13:14:04 +020012- Issue #20437: Fixed 43 potential bugs when deleting objects references.

15 systems supporting anonymous memory mappings. Patch by Charles-François

19 IndentationError.
20
Gregory P. Smith7902f8d2014-01-06 09:50:19 -080021- Issue #19081: When a zipimport .zip file in sys.path being imported from
22 is modified during the lifetime of the Python process after zipimport has
23 already cached the zip's table of contents we detect this and recover
24 rather than read bad data from the .zip (causing odd import errors).
25
Benjamin Peterson22d9ee72013-12-28 10:33:58 -060026- Raise a better error when non-unicode codecs are used for a file's coding
27 cookie.

31 and Victor Stinner.
32
Victor Stinner66c6e9d2013-12-13 02:37:09 +010033- Issue #14432: Generator now clears the borrowed reference to the thread
34 state. Fix a crash when a generator is created in a C thread that is
35 destroyed while the generator is still used. The issue was that a generator
36 contains a frame, and the frame kept a reference to the Python state of the
37 destroyed C thread. The crash occurs when a trace function is setup.

R David Murray2cfae9b2014-02-08 17:54:12 -050050- Issue #14983: email.generator now always adds a line end after each MIME

618 options like -fwrapv were overridden and thus not used, which could result
619 in broken interpreters when building with clang.

1666 In particular, fix extension module build failures when trying to use
1667 32-bit-only installer Pythons on systems with Xcode 4 (currently
1668 OS X 10.8, 10.7, and optionally 10.6).
1669 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1670 * Since Xcode 4 removes ppc support, extension module builds now
1671 check for ppc compiler support and by default remove ppc and
1672 ppc64 archs when they are not available.
1673 * Extension module builds now revert to using system installed
1674 headers and libs (/usr and /System/Library) if the SDK used
1675 to build the interpreter is not installed or has moved.
1676 * Try to avoid building extension modules with deprecated
1677 and problematic Apple llvm-gcc compiler. If original compiler
1678 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002102- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002103 has left two versions of customize_compiler, the original in
2104 distutils.sysconfig and another copy in distutils.ccompiler, with some

2107 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002109- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2110 Distutils-based packages with C extension modules may fail because
2111 Apple has removed gcc-4.2, the version used to build python.org
2112 64-bit/32-bit Pythons. If the user does not explicitly override
2113 the default C compiler by setting the CC environment variable,
2114 Distutils will now attempt to compile extension modules with clang
2115 if gcc-4.2 is required but not found. Also as a convenience, if
2116 the user does explicitly set CC, substitute its value as the default
2117 compiler in the Distutils LDSHARED configuration variable for OS X.
2118 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2119 SDK, neither of which are available in Xcode 4. This change does not
2120 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002370- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2371 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2372 interpreter process. This could cause failures in non-Distutils subprocesses
2373 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002374 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002375 deployment target only in the environment of each build subprocess. It is
2376 still possible to globally override the default by setting
2377 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2378 greater or equal to the default value, the value with which the interpreter
2379 was built.

2408 updating the check interval, so if the user decreases the check interval,
2409 the ticker doesn't have to wind down to zero from the old starting point
2410 before the new interval takes effect. And if the user increases the
2411 interval, it makes sure the new limit takes effect right away rather have an
2412 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003237- Issue #9869: Make long() and PyNumber_Long return something of type
3238 long for a class whose __long__ method returns a plain int. This
3239 fixes an interpreter crash when initializing an instance of a long
3240 subclass from an object whose __long__ method returns a plain int.

3245 thread-local storage key.
3246
Victor Stinnercaafd772010-09-08 10:51:01 +00003247- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3248 encoding and errors attributes instead of using utf-8 in strict mode, to get
3249 the same behaviour than the print statement.
3250
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00003251- Issue #9737: Fix a crash when trying to delete a slice or an item from

3391
Raymond Hettinger20397532010-09-12 02:11:45 +00003392- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3393 This prevents user-created self-referencing ordered dictionaries from
3394 becoming permanently uncollectable GC garbage. The downside is that
3395 removing __del__ means that the internal doubly-linked list has to wait for
3396 GC collection rather than freeing memory immediately when the refcnt drops
3397 to zero.
3398

3402
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003403- Issue #9792: In case of connection failure, socket.create_connection()
3404 would swallow the exception and raise a new one, making it impossible
3405 to fetch the original errno, or to filter timeout errors. Now the
3406 original error is re-raised.
3407

3410 be updated back after the system call. Original patch by Brian Brazil.

3427
R. David Murray7c4bf552010-08-25 01:45:57 +00003428- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3429 character years even if the message contains RFC822 two character years.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003855- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3856 start byte and the continuation byte(s) are now considered invalid, instead
3857 of the number of bytes specified by the start byte.
3858 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3859 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3860 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3871 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4257 with a non-empty format string. This is an effort to future-proof user
4258 code. If a derived class does not currently implement __format__ but later
4259 adds its own __format__, it would most likely break user code that had

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004753- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004754 file position when calling `truncate()`. It would previously change the file
4755 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004756 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00004758- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4759 class used to represent files stored inside an archive. The new
4760 implementation is significantly faster and can be wrapped in a
4761 ``io.BufferedReader`` object for more speedups. It also solves an issue
4762 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4852
Georg Brandlba83f822010-03-14 09:50:54 +00004853- The ``__complex__()`` method is now looked up on the class of instances to
4854 make it consistent with other special methods.

4858
Mark Dickinson1b34d252010-01-01 17:27:30 +00004859- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004860 DeprecationWarning when passed a float argument where an integer was expected.
4861 These functions and methods now raise TypeError instead. The majority of the
4862 effects of this change are in the extension modules, but some core functions
4863 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4864 and many unicode/str methods.

4878 of integers: the result of a/b is now correctly rounded for ints a and b (at
4879 least on IEEE 754 platforms), and in particular does not depend on the
4880 internal representation of a long.

4888
Georg Brandlba83f822010-03-14 09:50:54 +00004889 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005028- Issue #3382: 'F' formatting for float and complex now convert the result to
5029 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5030 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005031
Georg Brandlba83f822010-03-14 09:50:54 +00005032- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5033 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005034
Georg Brandlba83f822010-03-14 09:50:54 +00005035- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5036 1e-100 used to raise OverflowError, but now gives the requested 120
5037 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005045
Georg Brandlba83f822010-03-14 09:50:54 +00005046- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5047 decimal string that's guaranteed to round back to x under correct rounding
5048 (with round-half-to-even rounding mode). Previously it gave a string based on
5049 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5050 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5051 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005052
Georg Brandlba83f822010-03-14 09:50:54 +00005053- Issue #7117: On almost all platforms: float-to-string and string-to-float
5054 conversions within Python are now correctly rounded. Places these conversions
5055 occur include: str for floats and complex numbers; the float and complex
5056 constructors; old-style and new-style numeric formatting; serialization and
5057 deserialization of floats and complex numbers using marshal, pickle and json;
5058 parsing of float and imaginary literals in Python code; Decimal-to-float
5059 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005060
Georg Brandlba83f822010-03-14 09:50:54 +00005061 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5062 providing correctly-rounded strtod and dtoa C functions. This code is
5063 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5064 the C compiler. There may be a small number of platforms on which correct
5065 operation of this code cannot be guaranteed, so the code is not used: notably,
5066 this applies to platforms where the C double format is not IEEE 754 binary64,
5067 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5068 and Python's configure script is unable to determine how to change the FPU
5069 precision. On these platforms conversions use the platform strtod and dtoa,
5070 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005071
Georg Brandlba83f822010-03-14 09:50:54 +00005072- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5073 uses the correctly-rounded string <-> float conversions described above (when
5074 available), and so produces correctly rounded results that will display nicely
5075 under the float repr. There are two related small changes: (1) round now
5076 accepts any class with an ``__index__()`` method for its second argument (but
5077 no longer accepts floats for the second argument), and (2) an excessively
5078 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5079 raises an exception.

5082
Georg Brandlba83f822010-03-14 09:50:54 +00005083- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005220- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005221
Georg Brandlba83f822010-03-14 09:50:54 +00005222 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5223 (2) parsing of strings representing infinities and nans was locale aware; and
5224 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005226- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5227 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5228 but with at least one decimal point and with a default precision
5229 of 12. Previously, the behavior the same but with a default precision of 6.
5230 This more closely matches ``str()``, and reduces surprises when adding
5231 alignment flags to the empty presentation type. This also affects the new
5232 complex.__format__ in the same way.
5233
5234- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5235 classtype's, even if it was None. property now inserts the __doc__ into the
5236 subclass instance __dict__.

5458 this code path is really executed because I cannot move to such directory on

5463 eventual KeyError would always report the empty ``frozenset()`` as the missing

5485 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00006662 - If x is not an int, long or float, then packing x will always result in
6663 struct.error. Previously an x with an __int__ method could be packed by
6664 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6665 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6666 neither __int__ nor __long__, TypeError used to be raised (with a
6667 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6668 struct.error in other cases.

6671 argument with an __int__ method can be packed, but use of this feature
6672 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00006721 leak-chasing test runs give sensible results. The previous method of reaping
6722 threads could return successfully while some Thread objects were still
6723 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00006843- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006844 AttributeError instead of RuntimeError, depending in which C API call
6845 exactly the recursion limit is exceeded. Consequently, both exception types
6846 are caught and silenced.

6862
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006863- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6864
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006865- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6866 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6867 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6868 ``printf`` function, whereas PyString_FromFormat has an independent
6869 implementation and uses "%zd" on all platforms for size_t values.
6870 This makes a difference on win64, where ``printf`` needs "%Id" to display
6871 64bit values.
6872
Benjamin Peterson97179b02008-09-09 20:55:01 +00006873- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6874 error.
6875
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006876- Issue #3777: long() applied to a float object now always return a long
6877 object; previously an int would be returned for small values. the __long__
6878 method is allowed to return either an int or a long, but the behaviour of
6879 float objects should not change to respect backward compatibility.
6880
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006881- Issue #3751: str.rpartition would perform a left-partition when called with
6882 a unicode argument.
6883
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006884- Issue #3683: Fix compilation when --without-threads is given.
6885
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006886- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006887 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006888 was correctly parsed but parsing of subsequent arguments failed.
6889
Vinay Sajip35e3b032008-09-01 14:33:59 +00006890- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006891 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6892 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6893 when given a tuple of classes as second argument, were looking up
6894 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6895 type object.
6896
Neal Norwitz18aa3882008-08-24 05:04:52 +00006897- Fix crashes on memory allocation failure found with failmalloc.
6898
6899- Fix memory leaks found with valgrind and update suppressions file.
6900
6901- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6902
6903- Fix problem using wrong name in decimal module reported by pychecker.
6904
Christian Heimes7d4c3172008-08-22 19:47:25 +00006905- Silenced another compiler warning about a used but not defined
6906 function 'stringlib_contains_obj'.
6907
Benjamin Peterson712ee922008-08-24 18:10:20 +00006908- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6909 ``__delslice__``.
6910
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006911- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6912 library targets in the Makefile.
6913
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006914- Issue #1204: The configure script now tests for additional libraries
6915 that may be required when linking against readline. This fixes issues
6916 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

6927 stack usage in the case of deeply nested objects.
6928

Nick Coghland2e09382008-09-11 12:11:06 +00006939- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00006940 return a list or None rather than a custom object.
6941
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006942- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00006965- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00006966 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6967 for catch_warnings() also led to an improvement in the raising of a
6968 DeprecationWarning related to warnings.warn_explicit().
6969
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006970- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006993- Issue #2975: When compiling several extension modules with Visual Studio 2008
6994 from the same python interpreter, some environment variables would grow
6995 without limit.
6996
Benjamin Peterson37346b22008-08-23 20:27:43 +00006997- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6998 exploitation of poor argument checking.

7040-----------------
7041
Guido van Rossumf8402962008-08-20 15:01:50 +00007042- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7043 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7044 extensions do not automatically benefit from the class attribute
7045 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7046 to their tp_flags field if they care. This is a backwards
7047 compatibility feature; in 3.0, all types will use the cache by
7048 default.
7049
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007050- Keyword arguments can now follow starred arguments. (``f(a, *args,
7051 keyword=23)`` is now valid syntax.)
7052
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007053- ctypes function pointers that are COM methods have a boolean True
7054 value again.
7055
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007056- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7057 by denying s# to parse objects that have a releasebuffer procedure,
7058 and introducing s*.
7059
Georg Brandl1e13ea92008-08-11 09:07:59 +00007060- Issue #3537: Fix an assertion failure when an empty but presized dict
7061 object was stored in the freelist.
7062
Mark Dickinsonb6467572008-08-04 21:30:09 +00007063- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7064 ValueError consistently across platforms.
7065
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007066- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7067 (64bit Unix, for example), unichr() would truncate its argument and return
7068 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7069
Neal Norwitze7d8be82008-07-31 17:17:14 +00007070- Apply security patches from Apple.
7071
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007072- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7073 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7074
Antoine Pitrou92f82162008-07-25 22:22:08 +00007075- Issue #1819: function calls with several named parameters are now on
7076 average 35% faster (as measured by pybench).
7077
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007078- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7079 the python debugger steps into a class statement: the free variables (local
7080 variables defined in an outer scope) would be deleted from the outer scope.
7081
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007082- Issue #2620: Overflow checking when allocating or reallocating memory
7083 was not always being done properly in some python types and extension
7084 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7085 all been updated to perform better checks and places in the code that
7086 would previously leak memory on the error path when such an allocation
7087 failed have been fixed.

7093
Benjamin Petersone977ad42008-08-20 01:42:01 +00007094- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7095 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7096
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007097- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7098 version reported by these tools does not necessarily follow the python
7099 version numbering scheme, so the module is less strict when parsing it.
7100
Nick Coghlanf70385a2008-08-18 12:42:46 +00007101- Issue #2235: Added Py3k warnings for types which will become unhashable
7102 under the stricter __hash__ inheritance rules in 3.0. Several types
7103 which did not meet the rules for hash invariants and were already
7104 unhashable in 3.0 have now been explicitly flagged as unhashable in
7105 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7106 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7107
Brett Cannon88f801d2008-08-18 00:46:22 +00007108- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7109 imported into the module but exposed as part of the module's API.
7110
Brett Cannon7b96f072008-08-18 00:41:11 +00007111- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7112
Brett Cannon46225e72008-08-18 00:36:52 +00007113- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007115- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7116
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007117- Issue #3575: Incremental decoder's decode function now takes bytearray
7118 by using 's*' instead of 't#'.

7221
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007222- Issue #643841: The language reference now provides more detailed

7235
Georg Brandl3e483f62008-07-16 22:57:41 +00007236- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7237 its methods now allow for items objects that can be converted to
7238 an integer using operator.index().
7239
Mark Dickinson64b7e502008-07-16 09:40:03 +00007240- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7241 produced a ValueError instead of giving the correct float.
7242
Eric Smitha5fa5a22008-07-16 00:11:49 +00007243- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7244 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7245
Mark Dickinson7103aa42008-07-15 19:08:33 +00007246- Issue #3008: the float type has a new instance method 'float.hex'
7247 and a new class method 'float.fromhex' to convert floating-point
7248 numbers to and from hexadecimal strings, respectively.
7249
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007250- Issue #2235: __hash__ is once again inherited by default. To allow
7251 collections.Hashable to remain meaningful in the presence of the
7252 default hash implementation (object.__hash__), it is now possible
7253 to explicit block inheritance of hash by setting __hash__=None at
7254 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7255 level.
7256
Nick Coghlanb028f502008-07-13 14:52:36 +00007257- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7258 the parent module cannot be found while performing an absolute import.
7259 This means that an incorrectly defined __package__ attribute will
7260 now only prevent relative imports in that module rather than causing
7261 all imports from that module to fail.
7262
Nick Coghlan14ff9942008-07-08 14:21:42 +00007263- Issue #2517: Allow unicode messages in Exceptions again by correctly

7273 another thread's dictionary.
7274
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007275- Issue #3004: Minor change to slice.indices(): the start and stop
7276 arguments are now treated identically, making the behaviour easier
7277 to describe and understand. For example, slice(None, -10,
7278 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7279 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7280 10, -1).
7281
Georg Brandl278fc502008-07-19 12:46:12 +00007282- Issue #3219: Calling a function with repeated keyword arguments,
7283 f(a=2, a=23), would not cause a syntax error. This was a regression
7284 from 2.4 caused by the switch to the new compiler.

7323 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007324 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007325 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007730- On MacOS X it is now possible to install the framework in 64-bit
7731 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007732 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007733
7734 This is controlled by the configure argument ``--with-universal-archs``:
7735
7736 - ``--with-universal-archs=all``: install 4-way universal
7737
7738 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7739
7740 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7741
7742 This option should be used in combination with ``--enable-universalsdk=``.
7743
7744 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 +00007793- Issue #1631171: Re-implement the 'warnings' module in C (the
7794 original Python code has been kept as backup). This will allow for
7795 using the 'warning's machinery in such places as the parser where
7796 use of pure Python code is not possible. Both the ``showarning()``
7797 and ``formatwarning()`` gain an optional 'line' argument which is
7798 not called by default for backwards-compatibility reasons. Setting
7799 ``warnings.showwarning()`` to an implementation that lacks support
7800 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Issue #2550: The approach used by client/server code for obtaining
7864 ports to listen on in network-oriented tests has been refined in an
7865 effort to facilitate running multiple instances of the entire
7866 regression test suite in parallel without issue.
7867 test_support.bind_port() has been fixed such that it will always
7868 return a unique port -- which wasn't always the case with the
7869 previous implementation, especially if socket options had been set
7870 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7871 new implementation of bind_port() will actually raise an exception
7872 if it is passed an AF_INET/SOCK_STREAM socket with either the
7873 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7874 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7875 the socket it's been passed. This currently only applies to
7876 Windows. This option prevents any other sockets from binding to the
7877 host/port we've bound to, thus removing the possibility of the
7878 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7879 when a second SOCK_STREAM socket binds and accepts to a host/port
7880 that's already been bound by another socket. The optional preferred
7881 port parameter to bind_port() has been removed. Under no
7882 circumstances should tests be hard coding ports!
7883
7884 test_support.find_unused_port() has also been introduced, which will
7885 pass a temporary socket object to bind_port() in order to obtain an
7886 unused port. The temporary socket object is then closed and
7887 deleted, and the port is returned. This method should only be used
7888 for obtaining an unused port in order to pass to an external program
7889 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7890 a parameter to a server-oriented class that doesn't give you direct
7891 access to the underlying socket used.
7892
7893 Finally, test_support.HOST has been introduced, which should be used
7894 for the host argument of any relevant socket calls (i.e. bind and
7895 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007896
7897 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007898 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007899 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7900 test_asynchat and test_socket_ssl.
7901
Georg Brandl3ee81df2008-05-17 18:14:43 +00007902 It is now possible for multiple instances of the regression test
7903 suite to run in parallel without issue.

7959 Plane. This affected raw unicode literals and the
7960 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7961 this case, like normal unicode literals and the 'unicode-escape'
7962 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00008182- Added the future_builtins module, which contains hex() and oct().
8183 These are the PEP 3127 version of these functions, designed to be
8184 compatible with the hex() and oct() builtins from Python 3.0. They
8185 differ slightly in their output formats from the existing, unchanged
8186 Python 2.6 builtins. The expected usage of the future_builtins
8187 module is:
8188 from future_builtins import hex, oct
8189
Eric Smith7ef40bf2008-02-20 23:34:22 +00008190- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8191 exponents for exponents with absolute value < 100. Follows C99
8192 standard. This is a change on Windows, which would use 3 digits.
8193 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8194 so that any alterations it does to the resulting string will be
8195 available in stringlib/formatter.h (for float.__format__).
8196
Eric Smith5a3c1352008-02-19 13:21:56 +00008197- Implemented PEP 3101, Advanced String Formatting. This adds a new
8198 builtin format(); a format() method for str and unicode; a
8199 __format__() method to object, str, unicode, int, long, float, and
8200 datetime; the class string.Formatter; and the C API
8201 PyObject_Format().
8202
Georg Brandl3ee81df2008-05-17 18:14:43 +00008203- Fixed several potential crashes, all caused by specially crafted
8204 __del__ methods exploiting objects in temporarily inconsistent

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008207- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008208 prevent a possible crash: an Abstract Base Class would try to access
8209 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008210
Georg Brandl3ee81df2008-05-17 18:14:43 +00008211- Fixed repr() and str() of complex numbers with infinity or nan as
8212 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008214- Clear all free lists during a gc.collect() of the highest generation
8215 in order to allow pymalloc to free more arenas. Python may give back
8216 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Issue #2045: Fix an infinite recursion triggered when printing a
8219 subclass of collections.defaultdict, if its default_factory is set
8220 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008221
Christian Heimesf75dbef2008-02-08 00:11:31 +00008222- Fixed a minor memory leak in dictobject.c. The content of the free
8223 list was not freed on interpreter shutdown.
8224
Georg Brandl21e99f42010-03-07 15:23:59 +00008225- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008226 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008227
Georg Brandl3ee81df2008-05-17 18:14:43 +00008228- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8229 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008230 to compact the internal free lists of pre-allocted ints and floats.
8231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8233 calls. Python expected the return type int but the fork familie
8234 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008235
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8237 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008248- Patch #1473257: generator objects gain a gi_code attribute. This is
8249 the same object as the func_code attribute of the function that
8250 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Issue #1920: "while 0" statements were completely removed by the
8253 compiler, even in the presence of an "else" clause, which is
8254 supposed to be run when the condition is false. Now the compiler
8255 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008256
Guido van Rossumeead05f2008-01-24 18:21:02 +00008257- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008261- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008262 suppressed while an extension is loaded by calling SetErrorMode in
8263 dynload_win.c. The error is still reported properly.
8264
Georg Brandl3ee81df2008-05-17 18:14:43 +00008265- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008266 several extension methods and modules do not work without unicode
8267 support.
8268
Georg Brandl26543b12008-01-21 18:36:51 +00008269- Issue #1882: when compiling code from a string, encoding cookies in the

8273
Georg Brandl6caad7d2008-01-26 14:19:22 +00008274- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008275 added.
8276
Christian Heimesc94e2b52008-01-14 04:13:37 +00008277- sys.float_info / PyFloat_GetInfo: The floating point information
8278 object was converted from a dict to a specialized structseq object.
8279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Patch #1816: Added sys.flags structseq. It exposes the status of
8281 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Objects/structseq.c: Implemented new structseq representation. The
8284 patch makes structseqs (e.g. the return value of os.stat) more
8285 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008286
Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Patch #1700288: added a type attribute cache that caches method
8288 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008289
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008290- Bug #1776: __import__() no longer accepts filenames on any platform.
8291 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00008293- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8294
Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8296 envvar and sys.dont_write_bytecode attribute. All these can be set
8297 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008298
Georg Brandl3ee81df2008-05-17 18:14:43 +00008299- Improve some exception messages when Windows fails to load an
8300 extension module. Now we get for example '%1 is not a valid Win32
8301 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008302

Christian Heimes0a8143f2007-12-18 23:22:54 +00008308- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008309 and INF. float("nan"), float("inf") and float("-inf") now work on
8310 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008311
Georg Brandl3ee81df2008-05-17 18:14:43 +00008312- Compiler now generates simpler and faster code for dictionary
8313 literals. The oparg for BUILD_MAP now indicates an estimated
8314 dictionary size. There is a new opcode, STORE_MAP, for adding
8315 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008344- Patch #1739468: Directories and zipfiles containing a __main__.py
8345 file can now be directly executed by passing their name to the
8346 interpreter. The directory/zipfile is automatically inserted as the
8347 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008348
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Issue #1265: Fix a problem with sys.settrace, if the tracing
8350 function uses a generator expression when at the same time the
8351 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008352
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008353- sets and frozensets now have an isdisjoint() method.
8354
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008355- optimize the performance of builtin.sum().
8356
Neal Norwitz44f326e2007-10-05 05:29:17 +00008357- Fix warnings found by the new version of the Coverity checker.
8358
Georg Brandl21e99f42010-03-07 15:23:59 +00008359- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008360 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8361 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008362
Georg Brandl3ee81df2008-05-17 18:14:43 +00008363- Issue #1686386: Tuple's tp_repr did not take into account the
8364 possibility of having a self-referential tuple, which is possible
8365 from C code. Nor did object's tp_str consider that a type's tp_str
8366 could do something that could lead to an inifinite recursion.
8367 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8368 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008369
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370- Issue #1164: It was possible to trigger deadlock when using the
8371 'print' statement to write to a file since the GIL was not released
8372 as needed. Now PyObject_Print() does the right thing along with
8373 various tp_print implementations of the built-in types and those in
8374 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008375
Georg Brandl3ee81df2008-05-17 18:14:43 +00008376- Issue #1147: Exceptions were directly allowing string exceptions in
8377 their throw() method even though string exceptions no longer
8378 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Issue #1096: Prevent a segfault from getting the repr of a very
8381 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008382
Brett Cannon1e534b52007-09-07 04:18:30 +00008383- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384 PyObject_Call() never calling back out to Python code to trigger
8385 recursion depth updates/checks. Required the creation of a static
8386 RuntimeError instance in case normalizing an exception put the
8387 recursion check value past its limit. Fixes crashers
8388 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008389

Neal Norwitz0ac60192007-05-27 04:08:54 +00008403- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008404 __*__ attributes. (Some already existed, e.g., __doc__ and
8405 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008406
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008407- Add -3 option to the interpreter to warn about features that are
8408 deprecated and will be changed/removed in Python 3.0.
8409
Georg Brandl2134e752007-05-21 20:34:16 +00008410- Patch #1686487: you can now pass any mapping after '**' in function
8411 calls.
8412
Collin Winter62903052007-05-18 23:11:24 +00008413- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008414 "except E as target:". This is to provide forwards compatibility
8415 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008419- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008420 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008421
Vinay Sajip8549ce32007-05-06 17:53:37 +00008422- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008423 setting a plain string, ie don't expand to single letter identifiers.
8424
Raymond Hettinger13936692007-04-11 18:40:58 +00008425- Request #1191699: Slices can now be pickled.
8426
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008427- Request #1193128: str.translate() now allows a None argument for
8428 translations that only remove characters without re-mapping the
8429 remaining characters.
8430
Georg Brandl5cb76c12007-03-21 09:00:39 +00008431- Patch #1682205: a TypeError while unpacking an iterable is no longer
8432 masked by a generic one with the message "unpack non-sequence".
8433
Neal Norwitzaa754b72007-03-21 06:39:48 +00008434- Remove unused file Python/fmod.c.
8435
Guido van Rossum143b5642007-03-23 04:58:42 +00008436- Bug #1683368: The object.__init__() and object.__new__() methods are
8437 now stricter in rejecting excess arguments. The only time when
8438 either allows excess arguments is when it is not overridden and the
8439 other one is. For backwards compatibility, when both are
8440 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008441 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00008444- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8445 object to complex using its __complex__() method before falling back
8446 to the __float__() method. Therefore, the functions in the cmath
8447 module now can operate on objects that define a __complex__()
8448 method.

8468
Georg Brandl871f1bc2007-03-12 13:17:36 +00008469- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008470 its argument, if it exists. If not, it will work like before. This
8471 allows customizing the output of dir() in the presence of a
8472 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00008484- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008485 makes the filenames the warning module prints much more sensible
8486 when a PYTHONSTARTUP file is used.

8501
Georg Brandl3ee81df2008-05-17 18:14:43 +00008502- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008554- Bug #1545497: when given an explicit base, int() did ignore NULs
8555 embedded in the string to convert.
8556
Georg Brandl846f73a2006-10-08 07:11:54 +00008557- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008587- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008605 generator expressions (x for x, in ... ) works again. Fixing this
8606 problem required changing the .pyc magic number. This means that
8607 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009515 time so that opening a database previously created with the DB_DUP
9516 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9517 opens. Specifically: dictionary assignment to a DB object will
9518 replace all values for a given key when the database allows
9519 duplicate values. DB users should use DB.put(k, v) when they want
9520 to store duplicates; not DB[k] = v.

9527 characters with ASCII value less than 32. Also, it correctly quotes
9528 dots only if they occur on a single line, as opposed to the previous
9529 behavior of quoting dots if they are the second character of any
9530 line.
