1104 32-bit-only installer Pythons on systems with Xcode 4 (currently
1105 OS X 10.8, 10.7, and optionally 10.6).
1106 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1107 * Since Xcode 4 removes ppc support, extension module builds now
1108 check for ppc compiler support and by default remove ppc and
1109 ppc64 archs when they are not available.
1110 * Extension module builds now revert to using system installed
1111 headers and libs (/usr and /System/Library) if the SDK used
1112 to build the interpreter is not installed or has moved.
1113 * Try to avoid building extension modules with deprecated
1114 and problematic Apple llvm-gcc compiler. If original compiler
1115 is not available, use clang instead by default.

1483 cleared by the garbage collector. This fixes a segfault when an instance
1484 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01001539- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001540 has left two versions of customize_compiler, the original in
1541 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001546- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1547 Distutils-based packages with C extension modules may fail because
1548 Apple has removed gcc-4.2, the version used to build python.org
1549 64-bit/32-bit Pythons. If the user does not explicitly override
1550 the default C compiler by setting the CC environment variable,
1551 Distutils will now attempt to compile extension modules with clang
1552 if gcc-4.2 is required but not found. Also as a convenience, if
1553 the user does explicitly set CC, substitute its value as the default
1554 compiler in the Distutils LDSHARED configuration variable for OS X.
1555 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1556 SDK, neither of which are available in Xcode 4. This change does not
1557 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001807- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1808 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1809 interpreter process. This could cause failures in non-Distutils subprocesses
1810 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001811 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001812 deployment target only in the environment of each build subprocess. It is
1813 still possible to globally override the default by setting
1814 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1815 greater or equal to the default value, the value with which the interpreter
1816 was built.

1843
Barry Warsawc5643282011-07-19 17:06:30 -04001844- sys.setcheckinterval() now updates the current ticker count as well as
1845 updating the check interval, so if the user decreases the check interval,
1846 the ticker doesn't have to wind down to zero from the old starting point
1847 before the new interval takes effect. And if the user increases the
1848 interval, it makes sure the new limit takes effect right away rather have an
1849 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002674- Issue #9869: Make long() and PyNumber_Long return something of type
2675 long for a class whose __long__ method returns a plain int. This
2676 fixes an interpreter crash when initializing an instance of a long

2682 thread-local storage key.
2683
Victor Stinnercaafd772010-09-08 10:51:01 +00002684- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2685 encoding and errors attributes instead of using utf-8 in strict mode, to get
2686 the same behaviour than the print statement.
2687
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002688- Issue #9737: Fix a crash when trying to delete a slice or an item from

2703 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2704 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2817 fix various SSLSocket methods to raise socket.error rather than an
2818 unhelpful TypeError when called on an unconnected socket. Original patch
2819 by Andrew Bennetts.

2828
Raymond Hettinger20397532010-09-12 02:11:45 +00002829- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2830 This prevents user-created self-referencing ordered dictionaries from
2831 becoming permanently uncollectable GC garbage. The downside is that
2832 removing __del__ means that the internal doubly-linked list has to wait for
2833 GC collection rather than freeing memory immediately when the refcnt drops
2834 to zero.
2835
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002836- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2839
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002840- Issue #9792: In case of connection failure, socket.create_connection()
2841 would swallow the exception and raise a new one, making it impossible
2842 to fetch the original errno, or to filter timeout errors. Now the
2843 original error is re-raised.
2844
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002845- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2846 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2847 be updated back after the system call. Original patch by Brian Brazil.

2854
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002855- Issue #808164: Fixed socket.close to avoid references to globals, to

2860 heuristic. Patch by Terry Reedy and Eli Bendersky

2863 falling into recursion.
2864
R. David Murray7c4bf552010-08-25 01:45:57 +00002865- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2866 character years even if the message contains RFC822 two character years.
2867
Daniel Stutzbach91287322010-08-24 21:09:30 +00002868- Issue #8750: Fixed MutableSet's methods to correctly handle

2881
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002882- Issue #9617: Signals received during a low-level write operation aren't
2883 ignored by the buffered IO layer anymore.
2884
Benjamin Peterson52c36052010-08-21 03:03:22 +00002885- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2886 are not held onto after they are deleted elsewhere.
2887
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002888- Issue #9626: the view methods for collections.OrderedDict() were returning
2889 the unordered versions inherited from dict. Those methods are now
2890 overridden to provide ordered views.
2891
Éric Araujo0389ae62010-08-14 03:07:46 +00002892- Issue #8688: MANIFEST files created by distutils now include a magic
2893 comment indicating they are generated. Manually maintained MANIFESTs
2894 without this marker will not be overwritten or removed.
2895
Antoine Pitroue1436d12010-08-12 15:25:51 +00002896- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2897 and a BadZipfile error is raised if it doesn't match (as used to be the
2898 case in Python 2.5 and earlier).
2899
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002900- Issue #9550: a BufferedReader could issue an additional read when the
2901 original read request had been satisfied, which could block indefinitely
2902 when the underlying raw IO channel was e.g. a socket. Report and original
2903 patch by Jason V. Miller.
2904
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002905- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003293- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3294 start byte and the continuation byte(s) are now considered invalid, instead
3295 of the number of bytes specified by the start byte.
3296 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3297 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3298 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3308 objects. (1) The comparison could incorrectly return True in some cases
3309 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00003505- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3506 operation raises multiple signals and more than one of those signals is
3507 trapped, the specification determines the order in which the signals should be
3508 handled. In many cases this order wasn't being followed, leading to the wrong
3509 Python exception being raised.

3680
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003681- Issue #8329: Don't return the same lists from select.select when no fds are
3682 changed.

3695 with a non-empty format string. This is an effort to future-proof user
3696 code. If a derived class does not currently implement __format__ but later
3697 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003698 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003699 Python 3.3 and it will be an error in Python 3.4.

3772 Fractions instance now raise TypeError instead of returning True/False. This
3773 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3774 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004192 file position when calling `truncate()`. It would previously change the file
4193 position to the given argument, which goes against the tradition of

4197 class used to represent files stored inside an archive. The new
4198 implementation is significantly faster and can be wrapped in a
4199 ``io.BufferedReader`` object for more speedups. It also solves an issue
4200 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004291- The ``__complex__()`` method is now looked up on the class of instances to
4292 make it consistent with other special methods.

4296
Mark Dickinson1b34d252010-01-01 17:27:30 +00004297- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004298 DeprecationWarning when passed a float argument where an integer was expected.
4299 These functions and methods now raise TypeError instead. The majority of the
4300 effects of this change are in the extension modules, but some core functions
4301 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4302 and many unicode/str methods.

4317 least on IEEE 754 platforms), and in particular does not depend on the
4318 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004467- Issue #3382: 'F' formatting for float and complex now convert the result to
4468 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4469 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004470
Georg Brandlba83f822010-03-14 09:50:54 +00004471- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4472 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004473
Georg Brandlba83f822010-03-14 09:50:54 +00004474- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4475 1e-100 used to raise OverflowError, but now gives the requested 120
4476 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004484
Georg Brandlba83f822010-03-14 09:50:54 +00004485- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4486 decimal string that's guaranteed to round back to x under correct rounding
4487 (with round-half-to-even rounding mode). Previously it gave a string based on
4488 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4489 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4490 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004491
Georg Brandlba83f822010-03-14 09:50:54 +00004492- Issue #7117: On almost all platforms: float-to-string and string-to-float
4493 conversions within Python are now correctly rounded. Places these conversions
4494 occur include: str for floats and complex numbers; the float and complex
4495 constructors; old-style and new-style numeric formatting; serialization and
4496 deserialization of floats and complex numbers using marshal, pickle and json;
4497 parsing of float and imaginary literals in Python code; Decimal-to-float
4498 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004499
Georg Brandlba83f822010-03-14 09:50:54 +00004500 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4501 providing correctly-rounded strtod and dtoa C functions. This code is
4502 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4503 the C compiler. There may be a small number of platforms on which correct
4504 operation of this code cannot be guaranteed, so the code is not used: notably,
4505 this applies to platforms where the C double format is not IEEE 754 binary64,
4506 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4507 and Python's configure script is unable to determine how to change the FPU
4508 precision. On these platforms conversions use the platform strtod and dtoa,
4509 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004510
Georg Brandlba83f822010-03-14 09:50:54 +00004511- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4512 uses the correctly-rounded string <-> float conversions described above (when
4513 available), and so produces correctly rounded results that will display nicely
4514 under the float repr. There are two related small changes: (1) round now
4515 accepts any class with an ``__index__()`` method for its second argument (but
4516 no longer accepts floats for the second argument), and (2) an excessively
4517 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4518 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004660
Georg Brandlba83f822010-03-14 09:50:54 +00004661 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4662 (2) parsing of strings representing infinities and nans was locale aware; and
4663 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004665- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4666 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4667 but with at least one decimal point and with a default precision
4668 of 12. Previously, the behavior the same but with a default precision of 6.
4669 This more closely matches ``str()``, and reduces surprises when adding
4670 alignment flags to the empty presentation type. This also affects the new
4671 complex.__format__ in the same way.
4672
4673- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4674 classtype's, even if it was None. property now inserts the __doc__ into the
4675 subclass instance __dict__.

4745 internal representation of integers, for performance reasons. Base 2**30 is
4746 enabled by default on 64-bit machines. Add --enable-big-digits option to

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006283 AttributeError instead of RuntimeError, depending in which C API call
6284 exactly the recursion limit is exceeded. Consequently, both exception types
6285 are caught and silenced.

6301
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006302- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6303
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006304- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6305 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6306 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6307 ``printf`` function, whereas PyString_FromFormat has an independent
6308 implementation and uses "%zd" on all platforms for size_t values.
6309 This makes a difference on win64, where ``printf`` needs "%Id" to display
6310 64bit values.
6311
Benjamin Peterson97179b02008-09-09 20:55:01 +00006312- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6313 error.
6314
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006315- Issue #3777: long() applied to a float object now always return a long
6316 object; previously an int would be returned for small values. the __long__
6317 method is allowed to return either an int or a long, but the behaviour of
6318 float objects should not change to respect backward compatibility.
6319
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006320- Issue #3751: str.rpartition would perform a left-partition when called with
6321 a unicode argument.
6322
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006323- Issue #3683: Fix compilation when --without-threads is given.
6324
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006325- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006326 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006327 was correctly parsed but parsing of subsequent arguments failed.
6328
Vinay Sajip35e3b032008-09-01 14:33:59 +00006329- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006330 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6331 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6332 when given a tuple of classes as second argument, were looking up
6333 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6334 type object.
6335
Neal Norwitz18aa3882008-08-24 05:04:52 +00006336- Fix crashes on memory allocation failure found with failmalloc.
6337
6338- Fix memory leaks found with valgrind and update suppressions file.
6339
6340- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6341
6342- Fix problem using wrong name in decimal module reported by pychecker.
6343
Christian Heimes7d4c3172008-08-22 19:47:25 +00006344- Silenced another compiler warning about a used but not defined
6345 function 'stringlib_contains_obj'.
6346
Benjamin Peterson712ee922008-08-24 18:10:20 +00006347- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6348 ``__delslice__``.
6349
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006350- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6351 library targets in the Makefile.
6352
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006353- Issue #1204: The configure script now tests for additional libraries
6354 that may be required when linking against readline. This fixes issues
6355 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00006379 return a list or None rather than a custom object.
6380
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006381- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006405 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6406 for catch_warnings() also led to an improvement in the raising of a
6407 DeprecationWarning related to warnings.warn_explicit().
6408
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006409- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006473What's New in Python 2.6 beta 3?
6474================================
6475
Barry Warsaw07a4a382008-08-21 01:15:08 +00006476*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006477
6478Core and Builtins
6479-----------------
6480
Guido van Rossumf8402962008-08-20 15:01:50 +00006481- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6482 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6483 extensions do not automatically benefit from the class attribute
6484 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6485 to their tp_flags field if they care. This is a backwards
6486 compatibility feature; in 3.0, all types will use the cache by
6487 default.
6488
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006489- Keyword arguments can now follow starred arguments. (``f(a, *args,
6490 keyword=23)`` is now valid syntax.)
6491
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006492- ctypes function pointers that are COM methods have a boolean True
6493 value again.
6494
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006495- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6496 by denying s# to parse objects that have a releasebuffer procedure,
6497 and introducing s*.
6498
Georg Brandl1e13ea92008-08-11 09:07:59 +00006499- Issue #3537: Fix an assertion failure when an empty but presized dict
6500 object was stored in the freelist.
6501
Mark Dickinsonb6467572008-08-04 21:30:09 +00006502- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6503 ValueError consistently across platforms.
6504
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006505- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6506 (64bit Unix, for example), unichr() would truncate its argument and return
6507 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6508
Neal Norwitze7d8be82008-07-31 17:17:14 +00006509- Apply security patches from Apple.
6510
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006511- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6512 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6513
Antoine Pitrou92f82162008-07-25 22:22:08 +00006514- Issue #1819: function calls with several named parameters are now on
6515 average 35% faster (as measured by pybench).
6516
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006517- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6518 the python debugger steps into a class statement: the free variables (local
6519 variables defined in an outer scope) would be deleted from the outer scope.
6520
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006521- Issue #2620: Overflow checking when allocating or reallocating memory
6522 was not always being done properly in some python types and extension
6523 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6524 all been updated to perform better checks and places in the code that
6525 would previously leak memory on the error path when such an allocation
6526 failed have been fixed.

6532
Benjamin Petersone977ad42008-08-20 01:42:01 +00006533- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6534 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6535
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006536- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6537 version reported by these tools does not necessarily follow the python
6538 version numbering scheme, so the module is less strict when parsing it.
6539
Nick Coghlanf70385a2008-08-18 12:42:46 +00006540- Issue #2235: Added Py3k warnings for types which will become unhashable
6541 under the stricter __hash__ inheritance rules in 3.0. Several types
6542 which did not meet the rules for hash invariants and were already
6543 unhashable in 3.0 have now been explicitly flagged as unhashable in
6544 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6545 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6546
Brett Cannon88f801d2008-08-18 00:46:22 +00006547- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6548 imported into the module but exposed as part of the module's API.
6549
Brett Cannon7b96f072008-08-18 00:41:11 +00006550- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006554- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6555
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006556- Issue #3575: Incremental decoder's decode function now takes bytearray
6557 by using 's*' instead of 't#'.
6558
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006559- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006560 fails unicode conversion on 2nd parameter. (windows only)

Antoine Pitroude781a42008-08-09 12:43:23 +00006616 asking for a specific length. This problem only affected files opened

6660
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006661- Issue #643841: The language reference now provides more detailed

6673-----------------
6674
Georg Brandl3e483f62008-07-16 22:57:41 +00006675- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6676 its methods now allow for items objects that can be converted to
6677 an integer using operator.index().
6678
Mark Dickinson64b7e502008-07-16 09:40:03 +00006679- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6680 produced a ValueError instead of giving the correct float.
6681
Eric Smitha5fa5a22008-07-16 00:11:49 +00006682- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6683 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6684
Mark Dickinson7103aa42008-07-15 19:08:33 +00006685- Issue #3008: the float type has a new instance method 'float.hex'
6686 and a new class method 'float.fromhex' to convert floating-point
6687 numbers to and from hexadecimal strings, respectively.
6688
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006689- Issue #2235: __hash__ is once again inherited by default. To allow
6690 collections.Hashable to remain meaningful in the presence of the
6691 default hash implementation (object.__hash__), it is now possible
6692 to explicit block inheritance of hash by setting __hash__=None at
6693 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6694 level.
6695
Nick Coghlanb028f502008-07-13 14:52:36 +00006696- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6697 the parent module cannot be found while performing an absolute import.
6698 This means that an incorrectly defined __package__ attribute will
6699 now only prevent relative imports in that module rather than causing
6700 all imports from that module to fail.
6701
Nick Coghlan14ff9942008-07-08 14:21:42 +00006702- Issue #2517: Allow unicode messages in Exceptions again by correctly

6712 another thread's dictionary.
6713
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006714- Issue #3004: Minor change to slice.indices(): the start and stop
6715 arguments are now treated identically, making the behaviour easier
6716 to describe and understand. For example, slice(None, -10,
6717 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6718 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6719 10, -1).
6720
Georg Brandl278fc502008-07-19 12:46:12 +00006721- Issue #3219: Calling a function with repeated keyword arguments,
6722 f(a=2, a=23), would not cause a syntax error. This was a regression
6723 from 2.4 caused by the switch to the new compiler.

6733 api functions without holding the GIL, which could lead to a fatal
6734 error when they failed.
6735
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006736- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006761- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6762 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006763 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006764 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006780- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7170
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007171- On MacOS X it is now possible to install the framework in 64-bit
7172 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007173 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007174
7175 This is controlled by the configure argument ``--with-universal-archs``:
7176
7177 - ``--with-universal-archs=all``: install 4-way universal
7178
7179 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7180
7181 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7182
7183 This option should be used in combination with ``--enable-universalsdk=``.
7184
7185 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 +00007235- Issue #1631171: Re-implement the 'warnings' module in C (the
7236 original Python code has been kept as backup). This will allow for
7237 using the 'warning's machinery in such places as the parser where
7238 use of pure Python code is not possible. Both the ``showarning()``
7239 and ``formatwarning()`` gain an optional 'line' argument which is
7240 not called by default for backwards-compatibility reasons. Setting
7241 ``warnings.showwarning()`` to an implementation that lacks support
7242 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007284- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007285 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007305- Issue #2550: The approach used by client/server code for obtaining
7306 ports to listen on in network-oriented tests has been refined in an
7307 effort to facilitate running multiple instances of the entire
7308 regression test suite in parallel without issue.
7309 test_support.bind_port() has been fixed such that it will always
7310 return a unique port -- which wasn't always the case with the
7311 previous implementation, especially if socket options had been set
7312 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7313 new implementation of bind_port() will actually raise an exception
7314 if it is passed an AF_INET/SOCK_STREAM socket with either the
7315 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7316 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7317 the socket it's been passed. This currently only applies to
7318 Windows. This option prevents any other sockets from binding to the
7319 host/port we've bound to, thus removing the possibility of the
7320 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7321 when a second SOCK_STREAM socket binds and accepts to a host/port
7322 that's already been bound by another socket. The optional preferred
7323 port parameter to bind_port() has been removed. Under no
7324 circumstances should tests be hard coding ports!
7325
7326 test_support.find_unused_port() has also been introduced, which will
7327 pass a temporary socket object to bind_port() in order to obtain an
7328 unused port. The temporary socket object is then closed and
7329 deleted, and the port is returned. This method should only be used
7330 for obtaining an unused port in order to pass to an external program
7331 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7332 a parameter to a server-oriented class that doesn't give you direct
7333 access to the underlying socket used.
7334
7335 Finally, test_support.HOST has been introduced, which should be used
7336 for the host argument of any relevant socket calls (i.e. bind and
7337 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007338
7339 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007340 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007341 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7342 test_asynchat and test_socket_ssl.
7343
Georg Brandl3ee81df2008-05-17 18:14:43 +00007344 It is now possible for multiple instances of the regression test
7345 suite to run in parallel without issue.

7403 this case, like normal unicode literals and the 'unicode-escape'
7404 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007624- Added the future_builtins module, which contains hex() and oct().
7625 These are the PEP 3127 version of these functions, designed to be
7626 compatible with the hex() and oct() builtins from Python 3.0. They
7627 differ slightly in their output formats from the existing, unchanged
7628 Python 2.6 builtins. The expected usage of the future_builtins
7629 module is:
7630 from future_builtins import hex, oct
7631
Eric Smith7ef40bf2008-02-20 23:34:22 +00007632- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7633 exponents for exponents with absolute value < 100. Follows C99
7634 standard. This is a change on Windows, which would use 3 digits.
7635 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7636 so that any alterations it does to the resulting string will be
7637 available in stringlib/formatter.h (for float.__format__).
7638
Eric Smith5a3c1352008-02-19 13:21:56 +00007639- Implemented PEP 3101, Advanced String Formatting. This adds a new
7640 builtin format(); a format() method for str and unicode; a
7641 __format__() method to object, str, unicode, int, long, float, and
7642 datetime; the class string.Formatter; and the C API
7643 PyObject_Format().
7644
Georg Brandl3ee81df2008-05-17 18:14:43 +00007645- Fixed several potential crashes, all caused by specially crafted
7646 __del__ methods exploiting objects in temporarily inconsistent
7647 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007656- Clear all free lists during a gc.collect() of the highest generation
7657 in order to allow pymalloc to free more arenas. Python may give back
7658 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Issue #2045: Fix an infinite recursion triggered when printing a
7661 subclass of collections.defaultdict, if its default_factory is set
7662 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007663
Christian Heimesf75dbef2008-02-08 00:11:31 +00007664- Fixed a minor memory leak in dictobject.c. The content of the free
7665 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007690- Patch #1473257: generator objects gain a gi_code attribute. This is
7691 the same object as the func_code attribute of the function that
7692 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007693
Georg Brandl3ee81df2008-05-17 18:14:43 +00007694- Issue #1920: "while 0" statements were completely removed by the
7695 compiler, even in the presence of an "else" clause, which is
7696 supposed to be run when the condition is false. Now the compiler
7697 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007698
Guido van Rossumeead05f2008-01-24 18:21:02 +00007699- A few crashers fixed: weakref_in_del.py (issue #1377858);
7700 loosing_dict_ref.py (issue #1303614, test67.py);
7701 borrowed_ref_[34].py (not in tracker).
7702
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007703- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007704 suppressed while an extension is loaded by calling SetErrorMode in
7705 dynload_win.c. The error is still reported properly.
7706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007708 several extension methods and modules do not work without unicode
7709 support.
7710
Georg Brandl26543b12008-01-21 18:36:51 +00007711- Issue #1882: when compiling code from a string, encoding cookies in the

7715
Georg Brandl6caad7d2008-01-26 14:19:22 +00007716- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007717 added.
7718
Christian Heimesc94e2b52008-01-14 04:13:37 +00007719- sys.float_info / PyFloat_GetInfo: The floating point information
7720 object was converted from a dict to a specialized structseq object.
7721
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- Patch #1816: Added sys.flags structseq. It exposes the status of
7723 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007724
Georg Brandl3ee81df2008-05-17 18:14:43 +00007725- Objects/structseq.c: Implemented new structseq representation. The
7726 patch makes structseqs (e.g. the return value of os.stat) more
7727 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007728
Georg Brandl3ee81df2008-05-17 18:14:43 +00007729- Patch #1700288: added a type attribute cache that caches method
7730 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007731
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007732- Bug #1776: __import__() no longer accepts filenames on any platform.
7733 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00007735- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7736
Georg Brandl3ee81df2008-05-17 18:14:43 +00007737- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7738 envvar and sys.dont_write_bytecode attribute. All these can be set
7739 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007740
Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- Improve some exception messages when Windows fails to load an
7742 extension module. Now we get for example '%1 is not a valid Win32
7743 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007744

Christian Heimes0a8143f2007-12-18 23:22:54 +00007750- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007751 and INF. float("nan"), float("inf") and float("-inf") now work on
7752 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007753
Georg Brandl3ee81df2008-05-17 18:14:43 +00007754- Compiler now generates simpler and faster code for dictionary
7755 literals. The oparg for BUILD_MAP now indicates an estimated
7756 dictionary size. There is a new opcode, STORE_MAP, for adding
7757 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007786- Patch #1739468: Directories and zipfiles containing a __main__.py
7787 file can now be directly executed by passing their name to the
7788 interpreter. The directory/zipfile is automatically inserted as the
7789 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007791- Issue #1265: Fix a problem with sys.settrace, if the tracing
7792 function uses a generator expression when at the same time the
7793 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007794
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007795- sets and frozensets now have an isdisjoint() method.
7796
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007797- optimize the performance of builtin.sum().
7798

7800
Georg Brandl21e99f42010-03-07 15:23:59 +00007801- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007802 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7803 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007804
Georg Brandl3ee81df2008-05-17 18:14:43 +00007805- Issue #1686386: Tuple's tp_repr did not take into account the
7806 possibility of having a self-referential tuple, which is possible
7807 from C code. Nor did object's tp_str consider that a type's tp_str
7808 could do something that could lead to an inifinite recursion.
7809 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7810 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007811
Georg Brandl3ee81df2008-05-17 18:14:43 +00007812- Issue #1164: It was possible to trigger deadlock when using the
7813 'print' statement to write to a file since the GIL was not released
7814 as needed. Now PyObject_Print() does the right thing along with
7815 various tp_print implementations of the built-in types and those in
7816 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007817
Georg Brandl3ee81df2008-05-17 18:14:43 +00007818- Issue #1147: Exceptions were directly allowing string exceptions in
7819 their throw() method even though string exceptions no longer
7820 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00007825- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007826 PyObject_Call() never calling back out to Python code to trigger
7827 recursion depth updates/checks. Required the creation of a static
7828 RuntimeError instance in case normalizing an exception put the
7829 recursion check value past its limit. Fixes crashers
7830 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007831

Neal Norwitz0ac60192007-05-27 04:08:54 +00007845- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007846 __*__ attributes. (Some already existed, e.g., __doc__ and
7847 __name__.)

7851
Georg Brandl2134e752007-05-21 20:34:16 +00007852- Patch #1686487: you can now pass any mapping after '**' in function
7853 calls.
7854
Collin Winter62903052007-05-18 23:11:24 +00007855- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007856 "except E as target:". This is to provide forwards compatibility
7857 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007864- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007865 setting a plain string, ie don't expand to single letter identifiers.
7866
Raymond Hettinger13936692007-04-11 18:40:58 +00007867- Request #1191699: Slices can now be pickled.
7868
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007869- Request #1193128: str.translate() now allows a None argument for
7870 translations that only remove characters without re-mapping the
7871 remaining characters.
7872
Georg Brandl5cb76c12007-03-21 09:00:39 +00007873- Patch #1682205: a TypeError while unpacking an iterable is no longer

7877
Guido van Rossum143b5642007-03-23 04:58:42 +00007878- Bug #1683368: The object.__init__() and object.__new__() methods are
7879 now stricter in rejecting excess arguments. The only time when
7880 either allows excess arguments is when it is not overridden and the
7881 other one is. For backwards compatibility, when both are
7882 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007883 warning later). Also, type.__init__() insists on the same signature
7884 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007886- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7887 object to complex using its __complex__() method before falling back
7888 to the __float__() method. Therefore, the functions in the cmath
7889 module now can operate on objects that define a __complex__()
7890 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007912 its argument, if it exists. If not, it will work like before. This
7913 allows customizing the output of dir() in the presence of a
7914 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007926- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00007996- Bug #1545497: when given an explicit base, int() did ignore NULs
7997 embedded in the string to convert.
7998
Georg Brandl846f73a2006-10-08 07:11:54 +00007999- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008047 generator expressions (x for x, in ... ) works again. Fixing this
8048 problem required changing the .pyc magic number. This means that
8049 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008958 time so that opening a database previously created with the DB_DUP
8959 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8960 opens. Specifically: dictionary assignment to a DB object will
8961 replace all values for a given key when the database allows
8962 duplicate values. DB users should use DB.put(k, v) when they want
8963 to store duplicates; not DB[k] = v.

8970 characters with ASCII value less than 32. Also, it correctly quotes
8971 dots only if they occur on a single line, as opposed to the previous
8972 behavior of quoting dots if they are the second character of any
8973 line.
