Mark Dickinsondbbed042011-09-19 16:38:08 +0100324- Issue #12973: Fix overflow checks that invoked undefined behaviour in
325 int.__pow__. These overflow checks were causing int.__pow__ to produce
326 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100327 compiler optimizing the check away. Also fix similar overflow checks
328 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
329 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +0200340- Issue #12149: Update the method cache after a type's dictionnary gets
341 cleared by the garbage collector. This fixes a segfault when an instance
342 and its type get caught in a reference cycle, and the instance's
343 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +0100397- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100398 has left two versions of customize_compiler, the original in
399 distutils.sysconfig and another copy in distutils.ccompiler, with some
400 parts of distutils calling one and others using the other.

402 is the case in 3.x.
403
Ned Deily0d0ea482012-02-10 12:59:06 +0100404- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
405 Distutils-based packages with C extension modules may fail because
406 Apple has removed gcc-4.2, the version used to build python.org
407 64-bit/32-bit Pythons. If the user does not explicitly override
408 the default C compiler by setting the CC environment variable,
409 Distutils will now attempt to compile extension modules with clang
410 if gcc-4.2 is required but not found. Also as a convenience, if
411 the user does explicitly set CC, substitute its value as the default
412 compiler in the Distutils LDSHARED configuration variable for OS X.
413 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
414 SDK, neither of which are available in Xcode 4. This change does not
415 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700688- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
689 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
690 interpreter process. This could cause failures in non-Distutils subprocesses
691 and was unreliable since tests or user programs could modify the interpreter
692 environment after Distutils set it. Instead, have Distutils set the the
693 deployment target only in the environment of each build subprocess. It is
694 still possible to globally override the default by setting
695 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
696 greater or equal to the default value, the value with which the interpreter
697 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001678- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1679 This prevents user-created self-referencing ordered dictionaries from
1680 becoming permanently uncollectable GC garbage. The downside is that
1681 removing __del__ means that the internal doubly-linked list has to wait for
1682 GC collection rather than freeing memory immediately when the refcnt drops
1683 to zero.

1688

1691 to fetch the original errno, or to filter timeout errors. Now the
1692 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002142- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2143 start byte and the continuation byte(s) are now considered invalid, instead
2144 of the number of bytes specified by the start byte.
2145 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2146 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2158 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002354- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2355 operation raises multiple signals and more than one of those signals is
2356 trapped, the specification determines the order in which the signals should be
2357 handled. In many cases this order wasn't being followed, leading to the wrong
2358 Python exception being raised.

2408 indefinitely if the other end didn't respond.
2409
Georg Brandlfee0f442010-05-22 21:26:21 +00002410- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2411 SSL structure if necessary (as other methods already do).
Antoine Pitrou4d3e3722010-04-24 19:57:01 +00002412

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002528- Issue #7301: Add environment variable $PYTHONWARNINGS.
2529
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002530- Issue #8329: Don't return the same lists from select.select when no fds are
2531 changed.
2532
Georg Brandlfee0f442010-05-22 21:26:21 +00002533- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002534 on 64-bit machines. The shift count for either left or right shift is
2535 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002543- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2544 with a non-empty format string. This is an effort to future-proof user
2545 code. If a derived class does not currently implement __format__ but later
2546 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002547 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002548 Python 3.3 and it will be an error in Python 3.4.

2599 InvalidOperation instead of returning False. (Comparisons involving a quiet
2600 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2601 signaling NaNs remain unhashable.

2604 return a result based on the numeric values of the operands; previously they
2605 returned an arbitrary result based on the relative ordering of id(float) and
2606 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002609 argument `-` which tells it to read files to compile from stdin. Each line is
2610 read on demand and the named file is compiled immediately. (Original patch by
2611 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002620- Comparisons using one of <, <=, >, >= between a complex instance and a
2621 Fractions instance now raise TypeError instead of returning True/False. This
2622 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2623 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003040- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003041 file position when calling `truncate()`. It would previously change the file
3042 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003043 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3044
Georg Brandlba83f822010-03-14 09:50:54 +00003045- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3046 class used to represent files stored inside an archive. The new
3047 implementation is significantly faster and can be wrapped in a
3048 ``io.BufferedReader`` object for more speedups. It also solves an issue
3049 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3062 encoded string for them. This ensures that the upload and register commands
3063 send the correct values to PyPI without any error.

3138-----------------
3139
Georg Brandlba83f822010-03-14 09:50:54 +00003140- The ``__complex__()`` method is now looked up on the class of instances to
3141 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003143- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3144 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3145
Mark Dickinson1b34d252010-01-01 17:27:30 +00003146- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003147 DeprecationWarning when passed a float argument where an integer was expected.
3148 These functions and methods now raise TypeError instead. The majority of the
3149 effects of this change are in the extension modules, but some core functions
3150 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3151 and many unicode/str methods.

3165 of integers: the result of a/b is now correctly rounded for ints a and b (at
3166 least on IEEE 754 platforms), and in particular does not depend on the
3167 internal representation of a long.

3175
Georg Brandlba83f822010-03-14 09:50:54 +00003176 These executables now work properly with the arch(1) command: ``arch -ppc
3177 python`` will start a universal binary version of python in PPC mode (unlike

3268 TypeError. For the 'L' format code (which previously had no warning) there is
3269 now a DeprecationWarning.

3318 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003319
Georg Brandlba83f822010-03-14 09:50:54 +00003320- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3321 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003322
Georg Brandlba83f822010-03-14 09:50:54 +00003323- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3324 1e-100 used to raise OverflowError, but now gives the requested 120
3325 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003333
Georg Brandlba83f822010-03-14 09:50:54 +00003334- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3335 decimal string that's guaranteed to round back to x under correct rounding
3336 (with round-half-to-even rounding mode). Previously it gave a string based on
3337 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3338 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3339 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003340
Georg Brandlba83f822010-03-14 09:50:54 +00003341- Issue #7117: On almost all platforms: float-to-string and string-to-float
3342 conversions within Python are now correctly rounded. Places these conversions
3343 occur include: str for floats and complex numbers; the float and complex
3344 constructors; old-style and new-style numeric formatting; serialization and
3345 deserialization of floats and complex numbers using marshal, pickle and json;
3346 parsing of float and imaginary literals in Python code; Decimal-to-float
3347 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003348
Georg Brandlba83f822010-03-14 09:50:54 +00003349 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3350 providing correctly-rounded strtod and dtoa C functions. This code is
3351 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3352 the C compiler. There may be a small number of platforms on which correct
3353 operation of this code cannot be guaranteed, so the code is not used: notably,
3354 this applies to platforms where the C double format is not IEEE 754 binary64,
3355 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3356 and Python's configure script is unable to determine how to change the FPU
3357 precision. On these platforms conversions use the platform strtod and dtoa,
3358 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003359
Georg Brandlba83f822010-03-14 09:50:54 +00003360- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3361 uses the correctly-rounded string <-> float conversions described above (when
3362 available), and so produces correctly rounded results that will display nicely
3363 under the float repr. There are two related small changes: (1) round now
3364 accepts any class with an ``__index__()`` method for its second argument (but
3365 no longer accepts floats for the second argument), and (2) an excessively
3366 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3367 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003508- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003509
Georg Brandlba83f822010-03-14 09:50:54 +00003510 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3511 (2) parsing of strings representing infinities and nans was locale aware; and
3512 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003514- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3515 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3516 but with at least one decimal point and with a default precision
3517 of 12. Previously, the behavior the same but with a default precision of 6.
3518 This more closely matches ``str()``, and reduces surprises when adding
3519 alignment flags to the empty presentation type. This also affects the new
3520 complex.__format__ in the same way.
3521
3522- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3523 classtype's, even if it was None. property now inserts the __doc__ into the

3751 eventual KeyError would always report the empty ``frozenset()`` as the missing

3773 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3774 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3775 of using the replace error handler in PyUnicode_DecodeUTF8().

3782 gives improved memory leak detection when running under Valgrind, while taking
3783 advantage of pymalloc at other times.

4948 struct.error. Previously an x with an __int__ method could be packed by
4949 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4950 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4951 neither __int__ nor __long__, TypeError used to be raised (with a
4952 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4953 struct.error in other cases.

4956 argument with an __int__ method can be packed, but use of this feature
4957 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00005006 leak-chasing test runs give sensible results. The previous method of reaping
5007 threads could return successfully while some Thread objects were still
5008 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00005128- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005129 AttributeError instead of RuntimeError, depending in which C API call
5130 exactly the recursion limit is exceeded. Consequently, both exception types
5131 are caught and silenced.

5147
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005148- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5149
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005150- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5151 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5152 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5153 ``printf`` function, whereas PyString_FromFormat has an independent
5154 implementation and uses "%zd" on all platforms for size_t values.
5155 This makes a difference on win64, where ``printf`` needs "%Id" to display
5156 64bit values.
5157
Benjamin Peterson97179b02008-09-09 20:55:01 +00005158- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5159 error.
5160
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005161- Issue #3777: long() applied to a float object now always return a long
5162 object; previously an int would be returned for small values. the __long__
5163 method is allowed to return either an int or a long, but the behaviour of
5164 float objects should not change to respect backward compatibility.
5165
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005166- Issue #3751: str.rpartition would perform a left-partition when called with
5167 a unicode argument.
5168
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005169- Issue #3683: Fix compilation when --without-threads is given.
5170
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005171- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005172 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005173 was correctly parsed but parsing of subsequent arguments failed.
5174
Vinay Sajip35e3b032008-09-01 14:33:59 +00005175- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005176 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5177 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5178 when given a tuple of classes as second argument, were looking up
5179 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5180 type object.
5181
Neal Norwitz18aa3882008-08-24 05:04:52 +00005182- Fix crashes on memory allocation failure found with failmalloc.
5183
5184- Fix memory leaks found with valgrind and update suppressions file.
5185
5186- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5187
5188- Fix problem using wrong name in decimal module reported by pychecker.
5189
Christian Heimes7d4c3172008-08-22 19:47:25 +00005190- Silenced another compiler warning about a used but not defined
5191 function 'stringlib_contains_obj'.
5192
Benjamin Peterson712ee922008-08-24 18:10:20 +00005193- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5194 ``__delslice__``.
5195
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005196- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5197 library targets in the Makefile.
5198
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005199- Issue #1204: The configure script now tests for additional libraries
5200 that may be required when linking against readline. This fixes issues
5201 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

5212 stack usage in the case of deeply nested objects.
5213

Nick Coghland2e09382008-09-11 12:11:06 +00005224- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005225 return a list or None rather than a custom object.
5226
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005227- Issue #1638033: Cookie.Morsel gained the httponly attribute.
5228
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00005229- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Georg Brandl222e2082010-08-01 22:27:39 +00005250- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00005251 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5252 for catch_warnings() also led to an improvement in the raising of a
5253 DeprecationWarning related to warnings.warn_explicit().
5254
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005255- The deprecation warnings for the old camelCase threading API were removed.

5277
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005278- Issue #2975: When compiling several extension modules with Visual Studio 2008
5279 from the same python interpreter, some environment variables would grow
5280 without limit.
5281
Benjamin Peterson37346b22008-08-23 20:27:43 +00005282- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5324Core and Builtins
5325-----------------
5326
Guido van Rossumf8402962008-08-20 15:01:50 +00005327- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5328 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5329 extensions do not automatically benefit from the class attribute
5330 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5331 to their tp_flags field if they care. This is a backwards
5332 compatibility feature; in 3.0, all types will use the cache by
5333 default.
5334
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005335- Keyword arguments can now follow starred arguments. (``f(a, *args,
5336 keyword=23)`` is now valid syntax.)
5337
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005338- ctypes function pointers that are COM methods have a boolean True
5339 value again.
5340
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005341- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5342 by denying s# to parse objects that have a releasebuffer procedure,
5343 and introducing s*.
5344
Georg Brandl1e13ea92008-08-11 09:07:59 +00005345- Issue #3537: Fix an assertion failure when an empty but presized dict
5346 object was stored in the freelist.
5347
Mark Dickinsonb6467572008-08-04 21:30:09 +00005348- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5349 ValueError consistently across platforms.
5350
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005351- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5352 (64bit Unix, for example), unichr() would truncate its argument and return
5353 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5354
Neal Norwitze7d8be82008-07-31 17:17:14 +00005355- Apply security patches from Apple.
5356
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005357- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5358 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5359
Antoine Pitrou92f82162008-07-25 22:22:08 +00005360- Issue #1819: function calls with several named parameters are now on
5361 average 35% faster (as measured by pybench).
5362
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005363- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5364 the python debugger steps into a class statement: the free variables (local
5365 variables defined in an outer scope) would be deleted from the outer scope.
5366
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005367- Issue #2620: Overflow checking when allocating or reallocating memory
5368 was not always being done properly in some python types and extension
5369 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5370 all been updated to perform better checks and places in the code that
5371 would previously leak memory on the error path when such an allocation
5372 failed have been fixed.

5375-------
5376
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005377- Issue #3612: Added some missing basic types in ctypes.wintypes.
5378
Benjamin Petersone977ad42008-08-20 01:42:01 +00005379- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5380 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5381
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005382- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5383 version reported by these tools does not necessarily follow the python
5384 version numbering scheme, so the module is less strict when parsing it.
5385
Nick Coghlanf70385a2008-08-18 12:42:46 +00005386- Issue #2235: Added Py3k warnings for types which will become unhashable
5387 under the stricter __hash__ inheritance rules in 3.0. Several types
5388 which did not meet the rules for hash invariants and were already
5389 unhashable in 3.0 have now been explicitly flagged as unhashable in
5390 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5391 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5392
Brett Cannon88f801d2008-08-18 00:46:22 +00005393- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5394 imported into the module but exposed as part of the module's API.
5395
Brett Cannon7b96f072008-08-18 00:41:11 +00005396- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5397
Brett Cannon46225e72008-08-18 00:36:52 +00005398- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5399
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005400- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.

5506
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005507- Issue #643841: The language reference now provides more detailed

5519-----------------
5520
Georg Brandl3e483f62008-07-16 22:57:41 +00005521- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5522 its methods now allow for items objects that can be converted to
5523 an integer using operator.index().
5524
Mark Dickinson64b7e502008-07-16 09:40:03 +00005525- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5526 produced a ValueError instead of giving the correct float.
5527
Eric Smitha5fa5a22008-07-16 00:11:49 +00005528- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5529 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5530
Mark Dickinson7103aa42008-07-15 19:08:33 +00005531- Issue #3008: the float type has a new instance method 'float.hex'
5532 and a new class method 'float.fromhex' to convert floating-point
5533 numbers to and from hexadecimal strings, respectively.
5534
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005535- Issue #2235: __hash__ is once again inherited by default. To allow
5536 collections.Hashable to remain meaningful in the presence of the
5537 default hash implementation (object.__hash__), it is now possible
5538 to explicit block inheritance of hash by setting __hash__=None at
5539 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5540 level.
5541
Nick Coghlanb028f502008-07-13 14:52:36 +00005542- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5543 the parent module cannot be found while performing an absolute import.
5544 This means that an incorrectly defined __package__ attribute will
5545 now only prevent relative imports in that module rather than causing
5546 all imports from that module to fail.
5547
Nick Coghlan14ff9942008-07-08 14:21:42 +00005548- Issue #2517: Allow unicode messages in Exceptions again by correctly

5558 another thread's dictionary.
5559
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005560- Issue #3004: Minor change to slice.indices(): the start and stop
5561 arguments are now treated identically, making the behaviour easier
5562 to describe and understand. For example, slice(None, -10,
5563 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5564 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5565 10, -1).
5566
Georg Brandl278fc502008-07-19 12:46:12 +00005567- Issue #3219: Calling a function with repeated keyword arguments,
5568 f(a=2, a=23), would not cause a syntax error. This was a regression
5569 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005607- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5608 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005609 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005610 content-length. The problem had been corrected in the 2.4 branch, but never

5969 large to fit in a C long. ldexp(x, n) now returns a zero (with
5970 suitable sign) if n is large and negative; previously, it raised

6018 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006019 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006020
6021 This is controlled by the configure argument ``--with-universal-archs``:
6022
6023 - ``--with-universal-archs=all``: install 4-way universal
6024
6025 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6026
6027 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6028
6029 This option should be used in combination with ``--enable-universalsdk=``.
6030
6031 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 +00006081- Issue #1631171: Re-implement the 'warnings' module in C (the
6082 original Python code has been kept as backup). This will allow for
6083 using the 'warning's machinery in such places as the parser where
6084 use of pure Python code is not possible. Both the ``showarning()``
6085 and ``formatwarning()`` gain an optional 'line' argument which is
6086 not called by default for backwards-compatibility reasons. Setting
6087 ``warnings.showwarning()`` to an implementation that lacks support
6088 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006151- Issue #2550: The approach used by client/server code for obtaining
6152 ports to listen on in network-oriented tests has been refined in an
6153 effort to facilitate running multiple instances of the entire
6154 regression test suite in parallel without issue.
6155 test_support.bind_port() has been fixed such that it will always
6156 return a unique port -- which wasn't always the case with the
6157 previous implementation, especially if socket options had been set
6158 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6159 new implementation of bind_port() will actually raise an exception
6160 if it is passed an AF_INET/SOCK_STREAM socket with either the
6161 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6162 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6163 the socket it's been passed. This currently only applies to
6164 Windows. This option prevents any other sockets from binding to the
6165 host/port we've bound to, thus removing the possibility of the
6166 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6167 when a second SOCK_STREAM socket binds and accepts to a host/port
6168 that's already been bound by another socket. The optional preferred
6169 port parameter to bind_port() has been removed. Under no
6170 circumstances should tests be hard coding ports!
6171
6172 test_support.find_unused_port() has also been introduced, which will
6173 pass a temporary socket object to bind_port() in order to obtain an
6174 unused port. The temporary socket object is then closed and
6175 deleted, and the port is returned. This method should only be used
6176 for obtaining an unused port in order to pass to an external program
6177 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6178 a parameter to a server-oriented class that doesn't give you direct
6179 access to the underlying socket used.
6180
6181 Finally, test_support.HOST has been introduced, which should be used
6182 for the host argument of any relevant socket calls (i.e. bind and
6183 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006184
6185 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006186 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006187 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6188 test_asynchat and test_socket_ssl.
6189
Georg Brandl3ee81df2008-05-17 18:14:43 +00006190 It is now possible for multiple instances of the regression test
6191 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006245- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006246 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6247 Plane. This affected raw unicode literals and the
6248 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6249 this case, like normal unicode literals and the 'unicode-escape'
6250 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006470- Added the future_builtins module, which contains hex() and oct().
6471 These are the PEP 3127 version of these functions, designed to be
6472 compatible with the hex() and oct() builtins from Python 3.0. They
6473 differ slightly in their output formats from the existing, unchanged
6474 Python 2.6 builtins. The expected usage of the future_builtins
6475 module is:
6476 from future_builtins import hex, oct
6477
Eric Smith7ef40bf2008-02-20 23:34:22 +00006478- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6479 exponents for exponents with absolute value < 100. Follows C99
6480 standard. This is a change on Windows, which would use 3 digits.
6481 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6482 so that any alterations it does to the resulting string will be
6483 available in stringlib/formatter.h (for float.__format__).
6484
Eric Smith5a3c1352008-02-19 13:21:56 +00006485- Implemented PEP 3101, Advanced String Formatting. This adds a new
6486 builtin format(); a format() method for str and unicode; a
6487 __format__() method to object, str, unicode, int, long, float, and
6488 datetime; the class string.Formatter; and the C API
6489 PyObject_Format().
6490
Georg Brandl3ee81df2008-05-17 18:14:43 +00006491- Fixed several potential crashes, all caused by specially crafted
6492 __del__ methods exploiting objects in temporarily inconsistent
6493 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006494
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006495- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496 prevent a possible crash: an Abstract Base Class would try to access
6497 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006498

Georg Brandl3ee81df2008-05-17 18:14:43 +00006502- Clear all free lists during a gc.collect() of the highest generation
6503 in order to allow pymalloc to free more arenas. Python may give back
6504 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006505
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506- Issue #2045: Fix an infinite recursion triggered when printing a
6507 subclass of collections.defaultdict, if its default_factory is set
6508 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006509
Christian Heimesf75dbef2008-02-08 00:11:31 +00006510- Fixed a minor memory leak in dictobject.c. The content of the free
6511 list was not freed on interpreter shutdown.
6512
Georg Brandl21e99f42010-03-07 15:23:59 +00006513- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006514 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006515

6517 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006518 to compact the internal free lists of pre-allocted ints and floats.
6519
Georg Brandl3ee81df2008-05-17 18:14:43 +00006520- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6521 calls. Python expected the return type int but the fork familie
6522 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006536- Patch #1473257: generator objects gain a gi_code attribute. This is
6537 the same object as the func_code attribute of the function that
6538 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006539
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540- Issue #1920: "while 0" statements were completely removed by the
6541 compiler, even in the presence of an "else" clause, which is
6542 supposed to be run when the condition is false. Now the compiler
6543 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006544
Guido van Rossumeead05f2008-01-24 18:21:02 +00006545- A few crashers fixed: weakref_in_del.py (issue #1377858);
6546 loosing_dict_ref.py (issue #1303614, test67.py);
6547 borrowed_ref_[34].py (not in tracker).
6548
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006549- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006550 suppressed while an extension is loaded by calling SetErrorMode in
6551 dynload_win.c. The error is still reported properly.
6552
Georg Brandl3ee81df2008-05-17 18:14:43 +00006553- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006554 several extension methods and modules do not work without unicode
6555 support.
6556
Georg Brandl26543b12008-01-21 18:36:51 +00006557- Issue #1882: when compiling code from a string, encoding cookies in the

6561
Georg Brandl6caad7d2008-01-26 14:19:22 +00006562- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006563 added.
6564
Christian Heimesc94e2b52008-01-14 04:13:37 +00006565- sys.float_info / PyFloat_GetInfo: The floating point information
6566 object was converted from a dict to a specialized structseq object.
6567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Patch #1816: Added sys.flags structseq. It exposes the status of
6569 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006570
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571- Objects/structseq.c: Implemented new structseq representation. The
6572 patch makes structseqs (e.g. the return value of os.stat) more
6573 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Patch #1700288: added a type attribute cache that caches method
6576 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006577
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006578- Bug #1776: __import__() no longer accepts filenames on any platform.

6584 envvar and sys.dont_write_bytecode attribute. All these can be set
6585 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006586
Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- Improve some exception messages when Windows fails to load an
6588 extension module. Now we get for example '%1 is not a valid Win32
6589 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006596- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597 and INF. float("nan"), float("inf") and float("-inf") now work on
6598 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006599
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Compiler now generates simpler and faster code for dictionary
6601 literals. The oparg for BUILD_MAP now indicates an estimated
6602 dictionary size. There is a new opcode, STORE_MAP, for adding
6603 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006637- Issue #1265: Fix a problem with sys.settrace, if the tracing
6638 function uses a generator expression when at the same time the
6639 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006640
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006641- sets and frozensets now have an isdisjoint() method.
6642
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006643- optimize the performance of builtin.sum().

6646
Georg Brandl21e99f42010-03-07 15:23:59 +00006647- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6649 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006650
Georg Brandl3ee81df2008-05-17 18:14:43 +00006651- Issue #1686386: Tuple's tp_repr did not take into account the
6652 possibility of having a self-referential tuple, which is possible
6653 from C code. Nor did object's tp_str consider that a type's tp_str
6654 could do something that could lead to an inifinite recursion.
6655 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6656 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006657
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658- Issue #1164: It was possible to trigger deadlock when using the
6659 'print' statement to write to a file since the GIL was not released
6660 as needed. Now PyObject_Print() does the right thing along with
6661 various tp_print implementations of the built-in types and those in
6662 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006671- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672 PyObject_Call() never calling back out to Python code to trigger
6673 recursion depth updates/checks. Required the creation of a static
6674 RuntimeError instance in case normalizing an exception put the
6675 recursion check value past its limit. Fixes crashers
6676 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006692 __*__ attributes. (Some already existed, e.g., __doc__ and
6693 __name__.)

6699 calls.
6700
Collin Winter62903052007-05-18 23:11:24 +00006701- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006702 "except E as target:". This is to provide forwards compatibility
6703 with Python 3.0.

Armin Rigo9790a272007-05-02 19:23:31 +00006709
Vinay Sajip8549ce32007-05-06 17:53:37 +00006710- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006711 setting a plain string, ie don't expand to single letter identifiers.
6712
Raymond Hettinger13936692007-04-11 18:40:58 +00006713- Request #1191699: Slices can now be pickled.
6714
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006715- Request #1193128: str.translate() now allows a None argument for

6717 remaining characters.
6718
Georg Brandl5cb76c12007-03-21 09:00:39 +00006719- Patch #1682205: a TypeError while unpacking an iterable is no longer

6723
Guido van Rossum143b5642007-03-23 04:58:42 +00006724- Bug #1683368: The object.__init__() and object.__new__() methods are
6725 now stricter in rejecting excess arguments. The only time when
6726 either allows excess arguments is when it is not overridden and the
6727 other one is. For backwards compatibility, when both are
6728 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006729 warning later). Also, type.__init__() insists on the same signature
6730 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006732- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6733 object to complex using its __complex__() method before falling back
6734 to the __float__() method. Therefore, the functions in the cmath
6735 module now can operate on objects that define a __complex__()
6736 method.

6756
Georg Brandl871f1bc2007-03-12 13:17:36 +00006757- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006758 its argument, if it exists. If not, it will work like before. This
6759 allows customizing the output of dir() in the presence of a
6760 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006772- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006773 makes the filenames the warning module prints much more sensible
6774 when a PYTHONSTARTUP file is used.

6788 sq_ass_slice instead of the sq_slice slot.
6789
Georg Brandl3ee81df2008-05-17 18:14:43 +00006790- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006842- Bug #1545497: when given an explicit base, int() did ignore NULs
6843 embedded in the string to convert.
6844
Georg Brandl846f73a2006-10-08 07:11:54 +00006845- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006893 generator expressions (x for x, in ... ) works again. Fixing this
6894 problem required changing the .pyc magic number. This means that
6895 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007698- The implementation of UnicodeError objects has been simplified
7699 (start and end attributes are now stored directly as Py_ssize_t
7700 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007701
Georg Brandl3ee81df2008-05-17 18:14:43 +00007702- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7703 with RFC 3207 and forgets any knowledge obtained from the server not
7704 obtained from the TLS negotiation itself. Patch contributed by Bill
7705 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007708 that the SMTP.starttls() caller no longer needs to call ehlo()
7709 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710 does not claim to support starttls. Adds the
7711 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7712 Fenner.

7792 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7793 silently miscode subclasses of those types. Now, it raises a
7794 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007795

Georg Brandl3ee81df2008-05-17 18:14:43 +00007810 time so that opening a database previously created with the DB_DUP
7811 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7812 opens. Specifically: dictionary assignment to a DB object will
7813 replace all values for a given key when the database allows
7814 duplicate values. DB users should use DB.put(k, v) when they want
7815 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007816

7822 characters with ASCII value less than 32. Also, it correctly quotes
7823 dots only if they occur on a single line, as opposed to the previous
7824 behavior of quoting dots if they are the second character of any
7825 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007826

8233 solely on macfs and was a no-op under OS X.
