Mark Dickinsondbbed042011-09-19 16:38:08 +0100313- Issue #12973: Fix overflow checks that invoked undefined behaviour in
314 int.__pow__. These overflow checks were causing int.__pow__ to produce
315 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100316 compiler optimizing the check away. Also fix similar overflow checks
317 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
318 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +0100386- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100387 has left two versions of customize_compiler, the original in
388 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100393- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
394 Distutils-based packages with C extension modules may fail because
395 Apple has removed gcc-4.2, the version used to build python.org
396 64-bit/32-bit Pythons. If the user does not explicitly override
397 the default C compiler by setting the CC environment variable,
398 Distutils will now attempt to compile extension modules with clang
399 if gcc-4.2 is required but not found. Also as a convenience, if
400 the user does explicitly set CC, substitute its value as the default
401 compiler in the Distutils LDSHARED configuration variable for OS X.
402 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
403 SDK, neither of which are available in Xcode 4. This change does not
404 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700677- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
678 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
679 interpreter process. This could cause failures in non-Distutils subprocesses
680 and was unreliable since tests or user programs could modify the interpreter
681 environment after Distutils set it. Instead, have Distutils set the the
682 deployment target only in the environment of each build subprocess. It is
683 still possible to globally override the default by setting
684 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
685 greater or equal to the default value, the value with which the interpreter
686 was built.

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

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001512- Issue #9869: Make long() and PyNumber_Long return something of type
1513 long for a class whose __long__ method returns a plain int. This
1514 fixes an interpreter crash when initializing an instance of a long
1515 subclass from an object whose __long__ method returns a plain int.

1520 thread-local storage key.
1521
Victor Stinnercaafd772010-09-08 10:51:01 +00001522- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1523 encoding and errors attributes instead of using utf-8 in strict mode, to get
1524 the same behaviour than the print statement.
1525
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001526- Issue #9737: Fix a crash when trying to delete a slice or an item from

1666
Raymond Hettinger20397532010-09-12 02:11:45 +00001667- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1668 This prevents user-created self-referencing ordered dictionaries from
1669 becoming permanently uncollectable GC garbage. The downside is that
1670 removing __del__ means that the internal doubly-linked list has to wait for
1671 GC collection rather than freeing memory immediately when the refcnt drops
1672 to zero.
1673

1677
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001678- Issue #9792: In case of connection failure, socket.create_connection()
1679 would swallow the exception and raise a new one, making it impossible
1680 to fetch the original errno, or to filter timeout errors. Now the
1681 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002131- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2132 start byte and the continuation byte(s) are now considered invalid, instead
2133 of the number of bytes specified by the start byte.
2134 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2135 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2136 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2147 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002343- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2344 operation raises multiple signals and more than one of those signals is
2345 trapped, the specification determines the order in which the signals should be

Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002519- Issue #8329: Don't return the same lists from select.select when no fds are
2520 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00002532- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2533 with a non-empty format string. This is an effort to future-proof user
2534 code. If a derived class does not currently implement __format__ but later
2535 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002536 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002537 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitroud840e512010-02-04 20:20:18 +00003022- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003029- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003030 file position when calling `truncate()`. It would previously change the file
3031 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003032 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003034- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3035 class used to represent files stored inside an archive. The new
3036 implementation is significantly faster and can be wrapped in a
3037 ``io.BufferedReader`` object for more speedups. It also solves an issue
3038 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3127-----------------
3128
Georg Brandlba83f822010-03-14 09:50:54 +00003129- The ``__complex__()`` method is now looked up on the class of instances to
3130 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003132- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3133 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3134
Mark Dickinson1b34d252010-01-01 17:27:30 +00003135- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003136 DeprecationWarning when passed a float argument where an integer was expected.
3137 These functions and methods now raise TypeError instead. The majority of the
3138 effects of this change are in the extension modules, but some core functions
3139 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3140 and many unicode/str methods.

3154 of integers: the result of a/b is now correctly rounded for ints a and b (at
3155 least on IEEE 754 platforms), and in particular does not depend on the
3156 internal representation of a long.

3164
Georg Brandlba83f822010-03-14 09:50:54 +00003165 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003305- Issue #3382: 'F' formatting for float and complex now convert the result to
3306 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3307 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003308
Georg Brandlba83f822010-03-14 09:50:54 +00003309- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3310 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003311
Georg Brandlba83f822010-03-14 09:50:54 +00003312- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3313 1e-100 used to raise OverflowError, but now gives the requested 120
3314 significant digits instead.

3321 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003322
Georg Brandlba83f822010-03-14 09:50:54 +00003323- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3324 decimal string that's guaranteed to round back to x under correct rounding
3325 (with round-half-to-even rounding mode). Previously it gave a string based on
3326 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3327 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3328 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003329
Georg Brandlba83f822010-03-14 09:50:54 +00003330- Issue #7117: On almost all platforms: float-to-string and string-to-float
3331 conversions within Python are now correctly rounded. Places these conversions
3332 occur include: str for floats and complex numbers; the float and complex
3333 constructors; old-style and new-style numeric formatting; serialization and
3334 deserialization of floats and complex numbers using marshal, pickle and json;
3335 parsing of float and imaginary literals in Python code; Decimal-to-float
3336 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003337
Georg Brandlba83f822010-03-14 09:50:54 +00003338 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3339 providing correctly-rounded strtod and dtoa C functions. This code is
3340 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3341 the C compiler. There may be a small number of platforms on which correct
3342 operation of this code cannot be guaranteed, so the code is not used: notably,
3343 this applies to platforms where the C double format is not IEEE 754 binary64,
3344 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3345 and Python's configure script is unable to determine how to change the FPU
3346 precision. On these platforms conversions use the platform strtod and dtoa,
3347 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003348
Georg Brandlba83f822010-03-14 09:50:54 +00003349- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3350 uses the correctly-rounded string <-> float conversions described above (when
3351 available), and so produces correctly rounded results that will display nicely
3352 under the float repr. There are two related small changes: (1) round now
3353 accepts any class with an ``__index__()`` method for its second argument (but
3354 no longer accepts floats for the second argument), and (2) an excessively
3355 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3356 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003498
Georg Brandlba83f822010-03-14 09:50:54 +00003499 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3500 (2) parsing of strings representing infinities and nans was locale aware; and
3501 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003503- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3504 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3505 but with at least one decimal point and with a default precision
3506 of 12. Previously, the behavior the same but with a default precision of 6.
3507 This more closely matches ``str()``, and reduces surprises when adding
3508 alignment flags to the empty presentation type. This also affects the new
3509 complex.__format__ in the same way.

3511- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4939 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4940 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00004995 leak-chasing test runs give sensible results. The previous method of reaping
4996 threads could return successfully while some Thread objects were still
4997 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00005117- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005118 AttributeError instead of RuntimeError, depending in which C API call
5119 exactly the recursion limit is exceeded. Consequently, both exception types
5120 are caught and silenced.

5136
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005137- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5138
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005139- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5140 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5141 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5142 ``printf`` function, whereas PyString_FromFormat has an independent
5143 implementation and uses "%zd" on all platforms for size_t values.
5144 This makes a difference on win64, where ``printf`` needs "%Id" to display
5145 64bit values.
5146
Benjamin Peterson97179b02008-09-09 20:55:01 +00005147- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5148 error.
5149
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005150- Issue #3777: long() applied to a float object now always return a long
5151 object; previously an int would be returned for small values. the __long__
5152 method is allowed to return either an int or a long, but the behaviour of
5153 float objects should not change to respect backward compatibility.
5154
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005155- Issue #3751: str.rpartition would perform a left-partition when called with
5156 a unicode argument.
5157
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005158- Issue #3683: Fix compilation when --without-threads is given.
5159
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005160- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005161 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005162 was correctly parsed but parsing of subsequent arguments failed.
5163
Vinay Sajip35e3b032008-09-01 14:33:59 +00005164- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005165 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5166 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5167 when given a tuple of classes as second argument, were looking up
5168 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5169 type object.
5170
Neal Norwitz18aa3882008-08-24 05:04:52 +00005171- Fix crashes on memory allocation failure found with failmalloc.
5172
5173- Fix memory leaks found with valgrind and update suppressions file.
5174
5175- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5176
5177- Fix problem using wrong name in decimal module reported by pychecker.
5178
Christian Heimes7d4c3172008-08-22 19:47:25 +00005179- Silenced another compiler warning about a used but not defined
5180 function 'stringlib_contains_obj'.

5183 ``__delslice__``.
5184
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005185- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5186 library targets in the Makefile.
5187
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005188- Issue #1204: The configure script now tests for additional libraries
5189 that may be required when linking against readline. This fixes issues
5190 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

5201 stack usage in the case of deeply nested objects.
5202

Nick Coghland2e09382008-09-11 12:11:06 +00005213- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005214 return a list or None rather than a custom object.
5215
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005216- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005240 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5241 for catch_warnings() also led to an improvement in the raising of a
5242 DeprecationWarning related to warnings.warn_explicit().
5243
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005244- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005308What's New in Python 2.6 beta 3?
5309================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005312
5313Core and Builtins
5314-----------------
5315
Guido van Rossumf8402962008-08-20 15:01:50 +00005316- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5317 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5318 extensions do not automatically benefit from the class attribute
5319 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5320 to their tp_flags field if they care. This is a backwards
5321 compatibility feature; in 3.0, all types will use the cache by
5322 default.
5323
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005324- Keyword arguments can now follow starred arguments. (``f(a, *args,
5325 keyword=23)`` is now valid syntax.)
5326
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005327- ctypes function pointers that are COM methods have a boolean True
5328 value again.
5329
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005330- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5331 by denying s# to parse objects that have a releasebuffer procedure,
5332 and introducing s*.
5333
Georg Brandl1e13ea92008-08-11 09:07:59 +00005334- Issue #3537: Fix an assertion failure when an empty but presized dict
5335 object was stored in the freelist.
5336
Mark Dickinsonb6467572008-08-04 21:30:09 +00005337- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5338 ValueError consistently across platforms.
5339
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005340- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5341 (64bit Unix, for example), unichr() would truncate its argument and return
5342 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5343
Neal Norwitze7d8be82008-07-31 17:17:14 +00005344- Apply security patches from Apple.
5345
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005346- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5347 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5348
Antoine Pitrou92f82162008-07-25 22:22:08 +00005349- Issue #1819: function calls with several named parameters are now on
5350 average 35% faster (as measured by pybench).
5351
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005352- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5353 the python debugger steps into a class statement: the free variables (local
5354 variables defined in an outer scope) would be deleted from the outer scope.
5355
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005356- Issue #2620: Overflow checking when allocating or reallocating memory
5357 was not always being done properly in some python types and extension
5358 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5359 all been updated to perform better checks and places in the code that
5360 would previously leak memory on the error path when such an allocation
5361 failed have been fixed.

5365
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005366- Issue #3612: Added some missing basic types in ctypes.wintypes.
5367
Benjamin Petersone977ad42008-08-20 01:42:01 +00005368- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5369 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5370
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005371- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5372 version reported by these tools does not necessarily follow the python
5373 version numbering scheme, so the module is less strict when parsing it.
5374
Nick Coghlanf70385a2008-08-18 12:42:46 +00005375- Issue #2235: Added Py3k warnings for types which will become unhashable
5376 under the stricter __hash__ inheritance rules in 3.0. Several types
5377 which did not meet the rules for hash invariants and were already
5378 unhashable in 3.0 have now been explicitly flagged as unhashable in
5379 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5380 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5381
Brett Cannon88f801d2008-08-18 00:46:22 +00005382- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5383 imported into the module but exposed as part of the module's API.
5384
Brett Cannon7b96f072008-08-18 00:41:11 +00005385- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5386
Brett Cannon46225e72008-08-18 00:36:52 +00005387- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005389- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5390
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005391- Issue #3575: Incremental decoder's decode function now takes bytearray
5392 by using 's*' instead of 't#'.

5495
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005496- Issue #643841: The language reference now provides more detailed

5508-----------------
5509
Georg Brandl3e483f62008-07-16 22:57:41 +00005510- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5511 its methods now allow for items objects that can be converted to
5512 an integer using operator.index().
5513
Mark Dickinson64b7e502008-07-16 09:40:03 +00005514- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5515 produced a ValueError instead of giving the correct float.
5516
Eric Smitha5fa5a22008-07-16 00:11:49 +00005517- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5518 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5519
Mark Dickinson7103aa42008-07-15 19:08:33 +00005520- Issue #3008: the float type has a new instance method 'float.hex'
5521 and a new class method 'float.fromhex' to convert floating-point
5522 numbers to and from hexadecimal strings, respectively.
5523
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005524- Issue #2235: __hash__ is once again inherited by default. To allow
5525 collections.Hashable to remain meaningful in the presence of the
5526 default hash implementation (object.__hash__), it is now possible
5527 to explicit block inheritance of hash by setting __hash__=None at
5528 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5529 level.
5530
Nick Coghlanb028f502008-07-13 14:52:36 +00005531- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5532 the parent module cannot be found while performing an absolute import.
5533 This means that an incorrectly defined __package__ attribute will
5534 now only prevent relative imports in that module rather than causing
5535 all imports from that module to fail.
5536
Nick Coghlan14ff9942008-07-08 14:21:42 +00005537- Issue #2517: Allow unicode messages in Exceptions again by correctly
5538 bypassing the instance dictionary when looking up __unicode__ on
5539 new-style classes.

5547 another thread's dictionary.
5548
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005549- Issue #3004: Minor change to slice.indices(): the start and stop
5550 arguments are now treated identically, making the behaviour easier
5551 to describe and understand. For example, slice(None, -10,
5552 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5553 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5554 10, -1).
5555
Georg Brandl278fc502008-07-19 12:46:12 +00005556- Issue #3219: Calling a function with repeated keyword arguments,
5557 f(a=2, a=23), would not cause a syntax error. This was a regression
5558 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005560- Issue #2862: Make int and float freelist management consistent with
5561 other freelists. Changes their CompactFreeList apis into

5568 api functions without holding the GIL, which could lead to a fatal
5569 error when they failed.
5570
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005571- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005596- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5597 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005598 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005599 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005615- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5959 suitable sign) if n is large and negative; previously, it raised
5960 OverflowError.

6007 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006008 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006009
6010 This is controlled by the configure argument ``--with-universal-archs``:
6011
6012 - ``--with-universal-archs=all``: install 4-way universal
6013
6014 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6015
6016 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6017
6018 This option should be used in combination with ``--enable-universalsdk=``.
6019
6020 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 +00006070- Issue #1631171: Re-implement the 'warnings' module in C (the
6071 original Python code has been kept as backup). This will allow for
6072 using the 'warning's machinery in such places as the parser where
6073 use of pure Python code is not possible. Both the ``showarning()``
6074 and ``formatwarning()`` gain an optional 'line' argument which is
6075 not called by default for backwards-compatibility reasons. Setting
6076 ``warnings.showwarning()`` to an implementation that lacks support
6077 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006140- Issue #2550: The approach used by client/server code for obtaining
6141 ports to listen on in network-oriented tests has been refined in an
6142 effort to facilitate running multiple instances of the entire
6143 regression test suite in parallel without issue.
6144 test_support.bind_port() has been fixed such that it will always
6145 return a unique port -- which wasn't always the case with the
6146 previous implementation, especially if socket options had been set
6147 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6148 new implementation of bind_port() will actually raise an exception
6149 if it is passed an AF_INET/SOCK_STREAM socket with either the
6150 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6151 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6152 the socket it's been passed. This currently only applies to
6153 Windows. This option prevents any other sockets from binding to the
6154 host/port we've bound to, thus removing the possibility of the
6155 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6156 when a second SOCK_STREAM socket binds and accepts to a host/port
6157 that's already been bound by another socket. The optional preferred
6158 port parameter to bind_port() has been removed. Under no
6159 circumstances should tests be hard coding ports!
6160
6161 test_support.find_unused_port() has also been introduced, which will
6162 pass a temporary socket object to bind_port() in order to obtain an
6163 unused port. The temporary socket object is then closed and
6164 deleted, and the port is returned. This method should only be used
6165 for obtaining an unused port in order to pass to an external program
6166 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6167 a parameter to a server-oriented class that doesn't give you direct
6168 access to the underlying socket used.
6169
6170 Finally, test_support.HOST has been introduced, which should be used
6171 for the host argument of any relevant socket calls (i.e. bind and
6172 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006173
6174 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006175 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006176 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6177 test_asynchat and test_socket_ssl.
6178
Georg Brandl3ee81df2008-05-17 18:14:43 +00006179 It is now possible for multiple instances of the regression test
6180 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006234- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006235 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6236 Plane. This affected raw unicode literals and the
6237 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6238 this case, like normal unicode literals and the 'unicode-escape'
6239 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006459- Added the future_builtins module, which contains hex() and oct().
6460 These are the PEP 3127 version of these functions, designed to be
6461 compatible with the hex() and oct() builtins from Python 3.0. They
6462 differ slightly in their output formats from the existing, unchanged
6463 Python 2.6 builtins. The expected usage of the future_builtins
6464 module is:
6465 from future_builtins import hex, oct
6466
Eric Smith7ef40bf2008-02-20 23:34:22 +00006467- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6468 exponents for exponents with absolute value < 100. Follows C99
6469 standard. This is a change on Windows, which would use 3 digits.
6470 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6471 so that any alterations it does to the resulting string will be
6472 available in stringlib/formatter.h (for float.__format__).
6473
Eric Smith5a3c1352008-02-19 13:21:56 +00006474- Implemented PEP 3101, Advanced String Formatting. This adds a new
6475 builtin format(); a format() method for str and unicode; a
6476 __format__() method to object, str, unicode, int, long, float, and
6477 datetime; the class string.Formatter; and the C API
6478 PyObject_Format().
6479
Georg Brandl3ee81df2008-05-17 18:14:43 +00006480- Fixed several potential crashes, all caused by specially crafted
6481 __del__ methods exploiting objects in temporarily inconsistent
6482 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006483
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006484- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006485 prevent a possible crash: an Abstract Base Class would try to access
6486 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006487

Georg Brandl3ee81df2008-05-17 18:14:43 +00006491- Clear all free lists during a gc.collect() of the highest generation
6492 in order to allow pymalloc to free more arenas. Python may give back
6493 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006494
Georg Brandl3ee81df2008-05-17 18:14:43 +00006495- Issue #2045: Fix an infinite recursion triggered when printing a
6496 subclass of collections.defaultdict, if its default_factory is set
6497 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006525- Patch #1473257: generator objects gain a gi_code attribute. This is
6526 the same object as the func_code attribute of the function that
6527 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006528
Georg Brandl3ee81df2008-05-17 18:14:43 +00006529- Issue #1920: "while 0" statements were completely removed by the
6530 compiler, even in the presence of an "else" clause, which is
6531 supposed to be run when the condition is false. Now the compiler
6532 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006533
Guido van Rossumeead05f2008-01-24 18:21:02 +00006534- A few crashers fixed: weakref_in_del.py (issue #1377858);

6536 borrowed_ref_[34].py (not in tracker).
6537
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006538- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006539 suppressed while an extension is loaded by calling SetErrorMode in
6540 dynload_win.c. The error is still reported properly.
6541
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006543 several extension methods and modules do not work without unicode
6544 support.
6545
Georg Brandl26543b12008-01-21 18:36:51 +00006546- Issue #1882: when compiling code from a string, encoding cookies in the

6550
Georg Brandl6caad7d2008-01-26 14:19:22 +00006551- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006552 added.
6553
Christian Heimesc94e2b52008-01-14 04:13:37 +00006554- sys.float_info / PyFloat_GetInfo: The floating point information
6555 object was converted from a dict to a specialized structseq object.
6556
Georg Brandl3ee81df2008-05-17 18:14:43 +00006557- Patch #1816: Added sys.flags structseq. It exposes the status of
6558 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006559
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560- Objects/structseq.c: Implemented new structseq representation. The
6561 patch makes structseqs (e.g. the return value of os.stat) more
6562 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006563
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564- Patch #1700288: added a type attribute cache that caches method
6565 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006566
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006567- Bug #1776: __import__() no longer accepts filenames on any platform.

6573 envvar and sys.dont_write_bytecode attribute. All these can be set
6574 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006575
Georg Brandl3ee81df2008-05-17 18:14:43 +00006576- Improve some exception messages when Windows fails to load an
6577 extension module. Now we get for example '%1 is not a valid Win32
6578 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006585- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006586 and INF. float("nan"), float("inf") and float("-inf") now work on
6587 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006588
Georg Brandl3ee81df2008-05-17 18:14:43 +00006589- Compiler now generates simpler and faster code for dictionary
6590 literals. The oparg for BUILD_MAP now indicates an estimated
6591 dictionary size. There is a new opcode, STORE_MAP, for adding
6592 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006621- Patch #1739468: Directories and zipfiles containing a __main__.py
6622 file can now be directly executed by passing their name to the
6623 interpreter. The directory/zipfile is automatically inserted as the
6624 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006625
Georg Brandl3ee81df2008-05-17 18:14:43 +00006626- Issue #1265: Fix a problem with sys.settrace, if the tracing
6627 function uses a generator expression when at the same time the
6628 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006629
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006630- sets and frozensets now have an isdisjoint() method.
6631
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006632- optimize the performance of builtin.sum().

6635
Georg Brandl21e99f42010-03-07 15:23:59 +00006636- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6638 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006639
Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Issue #1686386: Tuple's tp_repr did not take into account the
6641 possibility of having a self-referential tuple, which is possible
6642 from C code. Nor did object's tp_str consider that a type's tp_str
6643 could do something that could lead to an inifinite recursion.
6644 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6645 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006646
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647- Issue #1164: It was possible to trigger deadlock when using the
6648 'print' statement to write to a file since the GIL was not released
6649 as needed. Now PyObject_Print() does the right thing along with
6650 various tp_print implementations of the built-in types and those in
6651 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006652
Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006660- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661 PyObject_Call() never calling back out to Python code to trigger
6662 recursion depth updates/checks. Required the creation of a static
6663 RuntimeError instance in case normalizing an exception put the
6664 recursion check value past its limit. Fixes crashers
6665 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006666

Georg Brandl3ee81df2008-05-17 18:14:43 +00006681 __*__ attributes. (Some already existed, e.g., __doc__ and
6682 __name__.)

6688 calls.
6689
Collin Winter62903052007-05-18 23:11:24 +00006690- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006691 "except E as target:". This is to provide forwards compatibility
6692 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006699- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006700 setting a plain string, ie don't expand to single letter identifiers.
6701
Raymond Hettinger13936692007-04-11 18:40:58 +00006702- Request #1191699: Slices can now be pickled.
6703
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006704- Request #1193128: str.translate() now allows a None argument for

6706 remaining characters.
6707
Georg Brandl5cb76c12007-03-21 09:00:39 +00006708- Patch #1682205: a TypeError while unpacking an iterable is no longer

6712
Guido van Rossum143b5642007-03-23 04:58:42 +00006713- Bug #1683368: The object.__init__() and object.__new__() methods are
6714 now stricter in rejecting excess arguments. The only time when
6715 either allows excess arguments is when it is not overridden and the
6716 other one is. For backwards compatibility, when both are
6717 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006718 warning later). Also, type.__init__() insists on the same signature
6719 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006721- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6722 object to complex using its __complex__() method before falling back
6723 to the __float__() method. Therefore, the functions in the cmath
6724 module now can operate on objects that define a __complex__()
6725 method.

6745
Georg Brandl871f1bc2007-03-12 13:17:36 +00006746- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006747 its argument, if it exists. If not, it will work like before. This
6748 allows customizing the output of dir() in the presence of a
6749 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006761- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006762 makes the filenames the warning module prints much more sensible
6763 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00006831- Bug #1545497: when given an explicit base, int() did ignore NULs
6832 embedded in the string to convert.
6833
Georg Brandl846f73a2006-10-08 07:11:54 +00006834- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006882 generator expressions (x for x, in ... ) works again. Fixing this
6883 problem required changing the .pyc magic number. This means that
6884 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007687- The implementation of UnicodeError objects has been simplified
7688 (start and end attributes are now stored directly as Py_ssize_t
7689 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007690
Georg Brandl3ee81df2008-05-17 18:14:43 +00007691- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7692 with RFC 3207 and forgets any knowledge obtained from the server not
7693 obtained from the TLS negotiation itself. Patch contributed by Bill
7694 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007695
Georg Brandl3ee81df2008-05-17 18:14:43 +00007696- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007697 that the SMTP.starttls() caller no longer needs to call ehlo()
7698 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699 does not claim to support starttls. Adds the
7700 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7701 Fenner.

7771 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773- Added wide char functions to msvcrt module: getwch, getwche, putwch

7781 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7782 silently miscode subclasses of those types. Now, it raises a
7783 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007784

Georg Brandl3ee81df2008-05-17 18:14:43 +00007799 time so that opening a database previously created with the DB_DUP
7800 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7801 opens. Specifically: dictionary assignment to a DB object will
7802 replace all values for a given key when the database allows
7803 duplicate values. DB users should use DB.put(k, v) when they want
7804 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007805

7811 characters with ASCII value less than 32. Also, it correctly quotes
7812 dots only if they occur on a single line, as opposed to the previous
7813 behavior of quoting dots if they are the second character of any
7814 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007815
