1080 In particular, fix extension module build failures when trying to use
1081 32-bit-only installer Pythons on systems with Xcode 4 (currently
1082 OS X 10.8, 10.7, and optionally 10.6).
1083 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1084 * Since Xcode 4 removes ppc support, extension module builds now
1085 check for ppc compiler support and by default remove ppc and
1086 ppc64 archs when they are not available.
1087 * Extension module builds now revert to using system installed
1088 headers and libs (/usr and /System/Library) if the SDK used
1089 to build the interpreter is not installed or has moved.
1090 * Try to avoid building extension modules with deprecated
1091 and problematic Apple llvm-gcc compiler. If original compiler
1092 is not available, use clang instead by default.

Ned Deilyc47a4592012-02-11 20:40:24 +01001517 has left two versions of customize_compiler, the original in
1518 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001523- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1524 Distutils-based packages with C extension modules may fail because
1525 Apple has removed gcc-4.2, the version used to build python.org
1526 64-bit/32-bit Pythons. If the user does not explicitly override
1527 the default C compiler by setting the CC environment variable,
1528 Distutils will now attempt to compile extension modules with clang
1529 if gcc-4.2 is required but not found. Also as a convenience, if
1530 the user does explicitly set CC, substitute its value as the default
1531 compiler in the Distutils LDSHARED configuration variable for OS X.
1532 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1533 SDK, neither of which are available in Xcode 4. This change does not
1534 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001784- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1785 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1786 interpreter process. This could cause failures in non-Distutils subprocesses
1787 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001788 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001789 deployment target only in the environment of each build subprocess. It is
1790 still possible to globally override the default by setting
1791 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1792 greater or equal to the default value, the value with which the interpreter
1793 was built.

1822 updating the check interval, so if the user decreases the check interval,
1823 the ticker doesn't have to wind down to zero from the old starting point
1824 before the new interval takes effect. And if the user increases the
1825 interval, it makes sure the new limit takes effect right away rather have an
1826 early task switch before recognizing the new interval.

2807 This prevents user-created self-referencing ordered dictionaries from
2808 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003270- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3271 start byte and the continuation byte(s) are now considered invalid, instead
3272 of the number of bytes specified by the start byte.
3273 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3274 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3275 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3276 Previous versions returned a single u'\ufffd'.

3280 arises from the "Overriding __eq__ blocks inheritance ..." warning
3281 when turned into an exception: in this case the exception simply
3282 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003284- Issue #8748: Fix two issues with comparisons between complex and integer
3285 objects. (1) The comparison could incorrectly return True in some cases
3286 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3287 (2) The comparison raised an OverflowError for large integers, leading
3288 to unpredictable exceptions when combining integers and complex objects
3289 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00003482- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3483 operation raises multiple signals and more than one of those signals is
3484 trapped, the specification determines the order in which the signals should be
3485 handled. In many cases this order wasn't being followed, leading to the wrong
3486 Python exception being raised.

3672 with a non-empty format string. This is an effort to future-proof user
3673 code. If a derived class does not currently implement __format__ but later
3674 adds its own __format__, it would most likely break user code that had

Georg Brandlfee0f442010-05-22 21:26:21 +00003726- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3727 InvalidOperation instead of returning False. (Comparisons involving a quiet
3728 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3729 signaling NaNs remain unhashable.

3733 returned an arbitrary result based on the relative ordering of id(float) and
3734 id(Decimal).

3738 read on demand and the named file is compiled immediately. (Original patch by
3739 Piotr Ożarowski).

3749 Fractions instance now raise TypeError instead of returning True/False. This
3750 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3751 <=> complex, and complex <=> complex comparisons.

3851 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003855- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3856 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3857 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003858 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3859 inconsistent: __int__ was used for some integer codes but not for others, and
3860 the set of integer codes for which it was used differed between native packing
3861 and standard packing.)

4170 position to the given argument, which goes against the tradition of

4174 class used to represent files stored inside an archive. The new
4175 implementation is significantly faster and can be wrapped in a

Georg Brandlba83f822010-03-14 09:50:54 +00004268- The ``__complex__()`` method is now looked up on the class of instances to
4269 make it consistent with other special methods.

4273
Mark Dickinson1b34d252010-01-01 17:27:30 +00004274- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004275 DeprecationWarning when passed a float argument where an integer was expected.
4276 These functions and methods now raise TypeError instead. The majority of the
4277 effects of this change are in the extension modules, but some core functions
4278 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4279 and many unicode/str methods.

4294 least on IEEE 754 platforms), and in particular does not depend on the
4295 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004441- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4442 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00004444- Issue #3382: 'F' formatting for float and complex now convert the result to
4445 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4446 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004447
Georg Brandlba83f822010-03-14 09:50:54 +00004448- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4449 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004450
Georg Brandlba83f822010-03-14 09:50:54 +00004451- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4452 1e-100 used to raise OverflowError, but now gives the requested 120
4453 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004454
Georg Brandlba83f822010-03-14 09:50:54 +00004455- Add Py3k warnings for parameter names in parentheses.

4460 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004461
Georg Brandlba83f822010-03-14 09:50:54 +00004462- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4463 decimal string that's guaranteed to round back to x under correct rounding
4464 (with round-half-to-even rounding mode). Previously it gave a string based on
4465 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4466 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4467 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004468
Georg Brandlba83f822010-03-14 09:50:54 +00004469- Issue #7117: On almost all platforms: float-to-string and string-to-float
4470 conversions within Python are now correctly rounded. Places these conversions
4471 occur include: str for floats and complex numbers; the float and complex
4472 constructors; old-style and new-style numeric formatting; serialization and
4473 deserialization of floats and complex numbers using marshal, pickle and json;
4474 parsing of float and imaginary literals in Python code; Decimal-to-float
4475 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004476
Georg Brandlba83f822010-03-14 09:50:54 +00004477 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4478 providing correctly-rounded strtod and dtoa C functions. This code is
4479 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4480 the C compiler. There may be a small number of platforms on which correct
4481 operation of this code cannot be guaranteed, so the code is not used: notably,
4482 this applies to platforms where the C double format is not IEEE 754 binary64,
4483 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4484 and Python's configure script is unable to determine how to change the FPU
4485 precision. On these platforms conversions use the platform strtod and dtoa,
4486 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004487
Georg Brandlba83f822010-03-14 09:50:54 +00004488- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4489 uses the correctly-rounded string <-> float conversions described above (when
4490 available), and so produces correctly rounded results that will display nicely
4491 under the float repr. There are two related small changes: (1) round now
4492 accepts any class with an ``__index__()`` method for its second argument (but
4493 no longer accepts floats for the second argument), and (2) an excessively
4494 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4495 raises an exception.

4498
Georg Brandlba83f822010-03-14 09:50:54 +00004499- Fix several issues with ``compile()``. The input can now contain Windows and

4532 breaks are now generated from the official Unicode Character Database files,
4533 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00004642- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4643 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4644 but with at least one decimal point and with a default precision
4645 of 12. Previously, the behavior the same but with a default precision of 6.
4646 This more closely matches ``str()``, and reduces surprises when adding
4647 alignment flags to the empty presentation type. This also affects the new
4648 complex.__format__ in the same way.

6278
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006279- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6280
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006281- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6282 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6283 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6284 ``printf`` function, whereas PyString_FromFormat has an independent
6285 implementation and uses "%zd" on all platforms for size_t values.
6286 This makes a difference on win64, where ``printf`` needs "%Id" to display
6287 64bit values.
6288
Benjamin Peterson97179b02008-09-09 20:55:01 +00006289- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6290 error.
6291
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006292- Issue #3777: long() applied to a float object now always return a long
6293 object; previously an int would be returned for small values. the __long__
6294 method is allowed to return either an int or a long, but the behaviour of
6295 float objects should not change to respect backward compatibility.
6296
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006297- Issue #3751: str.rpartition would perform a left-partition when called with
6298 a unicode argument.
6299
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006300- Issue #3683: Fix compilation when --without-threads is given.
6301
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006302- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006303 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006304 was correctly parsed but parsing of subsequent arguments failed.
6305
Vinay Sajip35e3b032008-09-01 14:33:59 +00006306- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006307 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6308 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6309 when given a tuple of classes as second argument, were looking up
6310 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6311 type object.
6312
Neal Norwitz18aa3882008-08-24 05:04:52 +00006313- Fix crashes on memory allocation failure found with failmalloc.
6314
6315- Fix memory leaks found with valgrind and update suppressions file.
6316
6317- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6318
6319- Fix problem using wrong name in decimal module reported by pychecker.
6320
Christian Heimes7d4c3172008-08-22 19:47:25 +00006321- Silenced another compiler warning about a used but not defined
6322 function 'stringlib_contains_obj'.
6323
Benjamin Peterson712ee922008-08-24 18:10:20 +00006324- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6325 ``__delslice__``.
6326
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006327- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6328 library targets in the Makefile.
6329
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006330- Issue #1204: The configure script now tests for additional libraries
6331 that may be required when linking against readline. This fixes issues
6332 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00006356 return a list or None rather than a custom object.
6357
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006358- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006382 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6383 for catch_warnings() also led to an improvement in the raising of a
6384 DeprecationWarning related to warnings.warn_explicit().
6385
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006386- The deprecation warnings for the old camelCase threading API were removed.

6408
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006409- Issue #2975: When compiling several extension modules with Visual Studio 2008
6410 from the same python interpreter, some environment variables would grow
6411 without limit.
6412
Benjamin Peterson37346b22008-08-23 20:27:43 +00006413- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6414 exploitation of poor argument checking.
6415
Gerhard Häringef2276b2008-09-12 13:54:06 +00006416- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006450What's New in Python 2.6 beta 3?
6451================================
6452
Barry Warsaw07a4a382008-08-21 01:15:08 +00006453*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006454
6455Core and Builtins
6456-----------------
6457
Guido van Rossumf8402962008-08-20 15:01:50 +00006458- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6459 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6460 extensions do not automatically benefit from the class attribute
6461 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6462 to their tp_flags field if they care. This is a backwards
6463 compatibility feature; in 3.0, all types will use the cache by
6464 default.
6465
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006466- Keyword arguments can now follow starred arguments. (``f(a, *args,
6467 keyword=23)`` is now valid syntax.)
6468
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006469- ctypes function pointers that are COM methods have a boolean True
6470 value again.
6471
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006472- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6473 by denying s# to parse objects that have a releasebuffer procedure,
6474 and introducing s*.
6475
Georg Brandl1e13ea92008-08-11 09:07:59 +00006476- Issue #3537: Fix an assertion failure when an empty but presized dict
6477 object was stored in the freelist.
6478
Mark Dickinsonb6467572008-08-04 21:30:09 +00006479- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6480 ValueError consistently across platforms.
6481
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006482- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6483 (64bit Unix, for example), unichr() would truncate its argument and return
6484 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6485
Neal Norwitze7d8be82008-07-31 17:17:14 +00006486- Apply security patches from Apple.
6487
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006488- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6489 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6490
Antoine Pitrou92f82162008-07-25 22:22:08 +00006491- Issue #1819: function calls with several named parameters are now on
6492 average 35% faster (as measured by pybench).
6493
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006494- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6495 the python debugger steps into a class statement: the free variables (local
6496 variables defined in an outer scope) would be deleted from the outer scope.
6497
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006498- Issue #2620: Overflow checking when allocating or reallocating memory
6499 was not always being done properly in some python types and extension
6500 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6501 all been updated to perform better checks and places in the code that
6502 would previously leak memory on the error path when such an allocation
6503 failed have been fixed.

6506-------
6507

6511 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6512
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006513- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6514 version reported by these tools does not necessarily follow the python
6515 version numbering scheme, so the module is less strict when parsing it.
6516
Nick Coghlanf70385a2008-08-18 12:42:46 +00006517- Issue #2235: Added Py3k warnings for types which will become unhashable
6518 under the stricter __hash__ inheritance rules in 3.0. Several types
6519 which did not meet the rules for hash invariants and were already
6520 unhashable in 3.0 have now been explicitly flagged as unhashable in
6521 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6522 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6523
Brett Cannon88f801d2008-08-18 00:46:22 +00006524- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6532
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006533- Issue #3575: Incremental decoder's decode function now takes bytearray
6534 by using 's*' instead of 't#'.
6535
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006536- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006537 fails unicode conversion on 2nd parameter. (windows only)
6538
Georg Brandl222e2082010-08-01 22:27:39 +00006539- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006540 in a redirect.
6541

Brett Cannon721b1452008-08-16 22:00:27 +00006543 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006544
Facundo Batistaeb90b782008-08-16 14:44:07 +00006545- Issue #2776: fixed small issue when handling an URL with double slash
6546 after a 302 response in the case of not going through a proxy.
6547
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006548- Issue #2676: in the email package, content-type parsing was hanging on
6549 pathological input because of quadratic or exponential behaviour of a
6550 regular expression.
6551
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006552- Issue #3476: binary buffered reading through the new "io" library is now

6556 since mimetools itself is deprecated. Because modules are cached, all
6557 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00006593 asking for a specific length. This problem only affected files opened

6637
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006638- Issue #643841: The language reference now provides more detailed

6650-----------------
6651
Georg Brandl3e483f62008-07-16 22:57:41 +00006652- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6653 its methods now allow for items objects that can be converted to
6654 an integer using operator.index().
6655
Mark Dickinson64b7e502008-07-16 09:40:03 +00006656- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6657 produced a ValueError instead of giving the correct float.
6658
Eric Smitha5fa5a22008-07-16 00:11:49 +00006659- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6660 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6661
Mark Dickinson7103aa42008-07-15 19:08:33 +00006662- Issue #3008: the float type has a new instance method 'float.hex'
6663 and a new class method 'float.fromhex' to convert floating-point
6664 numbers to and from hexadecimal strings, respectively.
6665
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006666- Issue #2235: __hash__ is once again inherited by default. To allow
6667 collections.Hashable to remain meaningful in the presence of the
6668 default hash implementation (object.__hash__), it is now possible
6669 to explicit block inheritance of hash by setting __hash__=None at
6670 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6671 level.
6672
Nick Coghlanb028f502008-07-13 14:52:36 +00006673- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6674 the parent module cannot be found while performing an absolute import.
6675 This means that an incorrectly defined __package__ attribute will
6676 now only prevent relative imports in that module rather than causing
6677 all imports from that module to fail.
6678
Nick Coghlan14ff9942008-07-08 14:21:42 +00006679- Issue #2517: Allow unicode messages in Exceptions again by correctly

6689 another thread's dictionary.
6690
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006691- Issue #3004: Minor change to slice.indices(): the start and stop
6692 arguments are now treated identically, making the behaviour easier
6693 to describe and understand. For example, slice(None, -10,
6694 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6695 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6696 10, -1).
6697
Georg Brandl278fc502008-07-19 12:46:12 +00006698- Issue #3219: Calling a function with repeated keyword arguments,
6699 f(a=2, a=23), would not cause a syntax error. This was a regression
6700 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006738- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6739 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006740 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006741 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006757- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007128- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007129 environment to control the '-arch' flags that are used to build
7130 an extension. This was added for compatibility with Apple's build
7131 of Python.
7132
7133- The bundled OSX-specific copy of libbffi is now in sync with the version
7134 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
7135
Georg Brandl25c34082008-08-18 23:09:49 +00007136- The threading module gained aliases for names that will be removed in the

7145
Brett Cannonb61d8012008-05-11 23:39:04 +00007146- ``Lib/lib-old`` is now added to sys.path.
7147
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007148- On MacOS X it is now possible to install the framework in 64-bit
7149 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007150 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007151
7152 This is controlled by the configure argument ``--with-universal-archs``:
7153
7154 - ``--with-universal-archs=all``: install 4-way universal
7155
7156 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7157
7158 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7159
7160 This option should be used in combination with ``--enable-universalsdk=``.
7161
7162 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 +00007212- Issue #1631171: Re-implement the 'warnings' module in C (the
7213 original Python code has been kept as backup). This will allow for
7214 using the 'warning's machinery in such places as the parser where
7215 use of pure Python code is not possible. Both the ``showarning()``
7216 and ``formatwarning()`` gain an optional 'line' argument which is
7217 not called by default for backwards-compatibility reasons. Setting
7218 ``warnings.showwarning()`` to an implementation that lacks support
7219 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007244- The getpass module has been improved on Unix. It now uses /dev/tty
7245 by default and uses stderr instead of stdout. A GetPassWarning is
7246 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007261- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007262 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007282- Issue #2550: The approach used by client/server code for obtaining
7283 ports to listen on in network-oriented tests has been refined in an
7284 effort to facilitate running multiple instances of the entire
7285 regression test suite in parallel without issue.
7286 test_support.bind_port() has been fixed such that it will always
7287 return a unique port -- which wasn't always the case with the
7288 previous implementation, especially if socket options had been set
7289 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7290 new implementation of bind_port() will actually raise an exception
7291 if it is passed an AF_INET/SOCK_STREAM socket with either the
7292 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7293 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7294 the socket it's been passed. This currently only applies to
7295 Windows. This option prevents any other sockets from binding to the
7296 host/port we've bound to, thus removing the possibility of the
7297 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7298 when a second SOCK_STREAM socket binds and accepts to a host/port
7299 that's already been bound by another socket. The optional preferred
7300 port parameter to bind_port() has been removed. Under no
7301 circumstances should tests be hard coding ports!
7302
7303 test_support.find_unused_port() has also been introduced, which will
7304 pass a temporary socket object to bind_port() in order to obtain an
7305 unused port. The temporary socket object is then closed and
7306 deleted, and the port is returned. This method should only be used
7307 for obtaining an unused port in order to pass to an external program
7308 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7309 a parameter to a server-oriented class that doesn't give you direct
7310 access to the underlying socket used.
7311
7312 Finally, test_support.HOST has been introduced, which should be used
7313 for the host argument of any relevant socket calls (i.e. bind and
7314 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007315
7316 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007317 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007318 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7319 test_asynchat and test_socket_ssl.
7320
Georg Brandl3ee81df2008-05-17 18:14:43 +00007321 It is now possible for multiple instances of the regression test
7322 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007601- Added the future_builtins module, which contains hex() and oct().
7602 These are the PEP 3127 version of these functions, designed to be
7603 compatible with the hex() and oct() builtins from Python 3.0. They
7604 differ slightly in their output formats from the existing, unchanged
7605 Python 2.6 builtins. The expected usage of the future_builtins
7606 module is:
7607 from future_builtins import hex, oct
7608
Eric Smith7ef40bf2008-02-20 23:34:22 +00007609- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7610 exponents for exponents with absolute value < 100. Follows C99
7611 standard. This is a change on Windows, which would use 3 digits.
7612 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7613 so that any alterations it does to the resulting string will be
7614 available in stringlib/formatter.h (for float.__format__).
7615
Eric Smith5a3c1352008-02-19 13:21:56 +00007616- Implemented PEP 3101, Advanced String Formatting. This adds a new
7617 builtin format(); a format() method for str and unicode; a
7618 __format__() method to object, str, unicode, int, long, float, and
7619 datetime; the class string.Formatter; and the C API
7620 PyObject_Format().
7621
Georg Brandl3ee81df2008-05-17 18:14:43 +00007622- Fixed several potential crashes, all caused by specially crafted
7623 __del__ methods exploiting objects in temporarily inconsistent
7624 state.

7628 a slot on a registered virtual subclass.

7634 in order to allow pymalloc to free more arenas. Python may give back
7635 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007636
Georg Brandl3ee81df2008-05-17 18:14:43 +00007637- Issue #2045: Fix an infinite recursion triggered when printing a
7638 subclass of collections.defaultdict, if its default_factory is set
7639 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007640
Christian Heimesf75dbef2008-02-08 00:11:31 +00007641- Fixed a minor memory leak in dictobject.c. The content of the free
7642 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00007644- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007645 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007646
Georg Brandl3ee81df2008-05-17 18:14:43 +00007647- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7648 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007649 to compact the internal free lists of pre-allocted ints and floats.
7650
Georg Brandl3ee81df2008-05-17 18:14:43 +00007651- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7652 calls. Python expected the return type int but the fork familie
7653 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007654
Georg Brandl3ee81df2008-05-17 18:14:43 +00007655- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7656 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007657
Georg Brandl3ee81df2008-05-17 18:14:43 +00007658- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7659 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007660
Georg Brandl3ee81df2008-05-17 18:14:43 +00007661- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7662 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00007664- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7665 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007666
Georg Brandl3ee81df2008-05-17 18:14:43 +00007667- Patch #1473257: generator objects gain a gi_code attribute. This is
7668 the same object as the func_code attribute of the function that
7669 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007670
Georg Brandl3ee81df2008-05-17 18:14:43 +00007671- Issue #1920: "while 0" statements were completely removed by the
7672 compiler, even in the presence of an "else" clause, which is
7673 supposed to be run when the condition is false. Now the compiler
7674 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007675
Guido van Rossumeead05f2008-01-24 18:21:02 +00007676- A few crashers fixed: weakref_in_del.py (issue #1377858);
7677 loosing_dict_ref.py (issue #1303614, test67.py);
7678 borrowed_ref_[34].py (not in tracker).
7679
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007680- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007681 suppressed while an extension is loaded by calling SetErrorMode in
7682 dynload_win.c. The error is still reported properly.
7683
Georg Brandl3ee81df2008-05-17 18:14:43 +00007684- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007685 several extension methods and modules do not work without unicode
7686 support.
7687
Georg Brandl26543b12008-01-21 18:36:51 +00007688- Issue #1882: when compiling code from a string, encoding cookies in the
7689 second line of code were not always recognized correctly.
7690
Georg Brandl14404b62008-01-19 19:27:05 +00007691- Issue #1679: "0x" was taken as a valid integer literal.
7692
Georg Brandl6caad7d2008-01-26 14:19:22 +00007693- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007694 added.
7695
Christian Heimesc94e2b52008-01-14 04:13:37 +00007696- sys.float_info / PyFloat_GetInfo: The floating point information
7697 object was converted from a dict to a specialized structseq object.
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Patch #1816: Added sys.flags structseq. It exposes the status of
7700 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007701
Georg Brandl3ee81df2008-05-17 18:14:43 +00007702- Objects/structseq.c: Implemented new structseq representation. The
7703 patch makes structseqs (e.g. the return value of os.stat) more
7704 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Patch #1700288: added a type attribute cache that caches method
7707 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007708
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007709- Bug #1776: __import__() no longer accepts filenames on any platform.
7710 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007711
Georg Brandlaed6c662008-01-07 17:25:53 +00007712- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7713
Georg Brandl3ee81df2008-05-17 18:14:43 +00007714- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7715 envvar and sys.dont_write_bytecode attribute. All these can be set
7716 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Improve some exception messages when Windows fails to load an
7719 extension module. Now we get for example '%1 is not a valid Win32
7720 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007721
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- Bug #1481296: Fixed long(float('nan')) != 0L.

7725 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007726
Christian Heimes0a8143f2007-12-18 23:22:54 +00007727- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728 and INF. float("nan"), float("inf") and float("-inf") now work on
7729 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007730
Georg Brandl3ee81df2008-05-17 18:14:43 +00007731- Compiler now generates simpler and faster code for dictionary
7732 literals. The oparg for BUILD_MAP now indicates an estimated
7733 dictionary size. There is a new opcode, STORE_MAP, for adding
7734 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007735
Georg Brandl3ee81df2008-05-17 18:14:43 +00007736- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007744- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007745 SystemError.
7746
Nick Coghlanef01d822007-12-03 12:55:17 +00007747- PEP 366: Allow explicit relative imports when executing modules
7748 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Patch #1739468: Directories and zipfiles containing a __main__.py
7764 file can now be directly executed by passing their name to the
7765 interpreter. The directory/zipfile is automatically inserted as the
7766 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007767
Georg Brandl3ee81df2008-05-17 18:14:43 +00007768- Issue #1265: Fix a problem with sys.settrace, if the tracing
7769 function uses a generator expression when at the same time the
7770 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007771
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007772- sets and frozensets now have an isdisjoint() method.
7773
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007774- optimize the performance of builtin.sum().
7775
Neal Norwitz44f326e2007-10-05 05:29:17 +00007776- Fix warnings found by the new version of the Coverity checker.
7777
Georg Brandl21e99f42010-03-07 15:23:59 +00007778- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7780 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007781
Georg Brandl3ee81df2008-05-17 18:14:43 +00007782- Issue #1686386: Tuple's tp_repr did not take into account the
7783 possibility of having a self-referential tuple, which is possible
7784 from C code. Nor did object's tp_str consider that a type's tp_str
7785 could do something that could lead to an inifinite recursion.
7786 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7787 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007788
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Issue #1164: It was possible to trigger deadlock when using the
7790 'print' statement to write to a file since the GIL was not released
7791 as needed. Now PyObject_Print() does the right thing along with
7792 various tp_print implementations of the built-in types and those in
7793 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007794
Georg Brandl3ee81df2008-05-17 18:14:43 +00007795- Issue #1147: Exceptions were directly allowing string exceptions in
7796 their throw() method even though string exceptions no longer
7797 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007798
Georg Brandl3ee81df2008-05-17 18:14:43 +00007799- Issue #1096: Prevent a segfault from getting the repr of a very
7800 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007801
Brett Cannon1e534b52007-09-07 04:18:30 +00007802- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007803 PyObject_Call() never calling back out to Python code to trigger
7804 recursion depth updates/checks. Required the creation of a static
7805 RuntimeError instance in case normalizing an exception put the
7806 recursion check value past its limit. Fixes crashers
7807 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007808
Georg Brandl3ee81df2008-05-17 18:14:43 +00007809- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007822- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823 __*__ attributes. (Some already existed, e.g., __doc__ and
7824 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007825
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007826- Add -3 option to the interpreter to warn about features that are
7827 deprecated and will be changed/removed in Python 3.0.
7828
Georg Brandl2134e752007-05-21 20:34:16 +00007829- Patch #1686487: you can now pass any mapping after '**' in function
7830 calls.
7831
Collin Winter62903052007-05-18 23:11:24 +00007832- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007833 "except E as target:". This is to provide forwards compatibility
7834 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007835
Brett Cannon229cee22007-05-05 01:34:02 +00007836- Deprecate BaseException.message as per PEP 352.
7837
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007839 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007841- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007842 setting a plain string, ie don't expand to single letter identifiers.
7843
Raymond Hettinger13936692007-04-11 18:40:58 +00007844- Request #1191699: Slices can now be pickled.
7845
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007846- Request #1193128: str.translate() now allows a None argument for
7847 translations that only remove characters without re-mapping the
7848 remaining characters.
7849
Georg Brandl5cb76c12007-03-21 09:00:39 +00007850- Patch #1682205: a TypeError while unpacking an iterable is no longer
7851 masked by a generic one with the message "unpack non-sequence".
7852
Neal Norwitzaa754b72007-03-21 06:39:48 +00007853- Remove unused file Python/fmod.c.
7854
Guido van Rossum143b5642007-03-23 04:58:42 +00007855- Bug #1683368: The object.__init__() and object.__new__() methods are
7856 now stricter in rejecting excess arguments. The only time when
7857 either allows excess arguments is when it is not overridden and the
7858 other one is. For backwards compatibility, when both are
7859 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007860 warning later). Also, type.__init__() insists on the same signature
7861 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7864 object to complex using its __complex__() method before falling back
7865 to the __float__() method. Therefore, the functions in the cmath
7866 module now can operate on objects that define a __complex__()
7867 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008415 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008456 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00008490- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008491 are set for invalid interpolation sequences that would lead to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008935 time so that opening a database previously created with the DB_DUP
8936 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8937 opens. Specifically: dictionary assignment to a DB object will
8938 replace all values for a given key when the database allows
8939 duplicate values. DB users should use DB.put(k, v) when they want
8940 to store duplicates; not DB[k] = v.

8947 characters with ASCII value less than 32. Also, it correctly quotes
8948 dots only if they occur on a single line, as opposed to the previous
8949 behavior of quoting dots if they are the second character of any
8950 line.
