665 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100670- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
671 Distutils-based packages with C extension modules may fail because
672 Apple has removed gcc-4.2, the version used to build python.org
673 64-bit/32-bit Pythons. If the user does not explicitly override
674 the default C compiler by setting the CC environment variable,
675 Distutils will now attempt to compile extension modules with clang
676 if gcc-4.2 is required but not found. Also as a convenience, if
677 the user does explicitly set CC, substitute its value as the default
678 compiler in the Distutils LDSHARED configuration variable for OS X.
679 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
680 SDK, neither of which are available in Xcode 4. This change does not
681 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700954- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
955 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
956 interpreter process. This could cause failures in non-Distutils subprocesses
957 and was unreliable since tests or user programs could modify the interpreter
958 environment after Distutils set it. Instead, have Distutils set the the
959 deployment target only in the environment of each build subprocess. It is
960 still possible to globally override the default by setting
961 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
962 greater or equal to the default value, the value with which the interpreter
963 was built.

993 the ticker doesn't have to wind down to zero from the old starting point
994 before the new interval takes effect. And if the user increases the
995 interval, it makes sure the new limit takes effect right away rather have an
996 early task switch before recognizing the new interval.

1793 long for a class whose __long__ method returns a plain int. This
1794 fixes an interpreter crash when initializing an instance of a long

1800 thread-local storage key.
1801
Victor Stinnercaafd772010-09-08 10:51:01 +00001802- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1803 encoding and errors attributes instead of using utf-8 in strict mode, to get
1804 the same behaviour than the print statement.
1805
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001806- Issue #9737: Fix a crash when trying to delete a slice or an item from

1946
Raymond Hettinger20397532010-09-12 02:11:45 +00001947- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1948 This prevents user-created self-referencing ordered dictionaries from
1949 becoming permanently uncollectable GC garbage. The downside is that
1950 removing __del__ means that the internal doubly-linked list has to wait for
1951 GC collection rather than freeing memory immediately when the refcnt drops
1952 to zero.
1953

1957
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001958- Issue #9792: In case of connection failure, socket.create_connection()
1959 would swallow the exception and raise a new one, making it impossible
1960 to fetch the original errno, or to filter timeout errors. Now the
1961 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002411- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2412 start byte and the continuation byte(s) are now considered invalid, instead
2413 of the number of bytes specified by the start byte.
2414 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2415 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2427 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002623- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2624 operation raises multiple signals and more than one of those signals is
2625 trapped, the specification determines the order in which the signals should be

2813 with a non-empty format string. This is an effort to future-proof user
2814 code. If a derived class does not currently implement __format__ but later
2815 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002816 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002817 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003309- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003310 file position when calling `truncate()`. It would previously change the file
3311 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003312 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003314- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3315 class used to represent files stored inside an archive. The new
3316 implementation is significantly faster and can be wrapped in a
3317 ``io.BufferedReader`` object for more speedups. It also solves an issue
3318 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3407-----------------
3408
Georg Brandlba83f822010-03-14 09:50:54 +00003409- The ``__complex__()`` method is now looked up on the class of instances to
3410 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003412- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3413 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3414
Mark Dickinson1b34d252010-01-01 17:27:30 +00003415- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003416 DeprecationWarning when passed a float argument where an integer was expected.
3417 These functions and methods now raise TypeError instead. The majority of the
3418 effects of this change are in the extension modules, but some core functions
3419 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3420 and many unicode/str methods.

3434 of integers: the result of a/b is now correctly rounded for ints a and b (at
3435 least on IEEE 754 platforms), and in particular does not depend on the
3436 internal representation of a long.

3444
Georg Brandlba83f822010-03-14 09:50:54 +00003445 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003585- Issue #3382: 'F' formatting for float and complex now convert the result to
3586 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3587 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003588
Georg Brandlba83f822010-03-14 09:50:54 +00003589- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3590 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003591
Georg Brandlba83f822010-03-14 09:50:54 +00003592- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3593 1e-100 used to raise OverflowError, but now gives the requested 120
3594 significant digits instead.

3601 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003602
Georg Brandlba83f822010-03-14 09:50:54 +00003603- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3604 decimal string that's guaranteed to round back to x under correct rounding
3605 (with round-half-to-even rounding mode). Previously it gave a string based on
3606 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3607 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3608 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003609
Georg Brandlba83f822010-03-14 09:50:54 +00003610- Issue #7117: On almost all platforms: float-to-string and string-to-float
3611 conversions within Python are now correctly rounded. Places these conversions
3612 occur include: str for floats and complex numbers; the float and complex
3613 constructors; old-style and new-style numeric formatting; serialization and
3614 deserialization of floats and complex numbers using marshal, pickle and json;
3615 parsing of float and imaginary literals in Python code; Decimal-to-float
3616 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003617
Georg Brandlba83f822010-03-14 09:50:54 +00003618 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3619 providing correctly-rounded strtod and dtoa C functions. This code is
3620 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3621 the C compiler. There may be a small number of platforms on which correct
3622 operation of this code cannot be guaranteed, so the code is not used: notably,
3623 this applies to platforms where the C double format is not IEEE 754 binary64,
3624 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3625 and Python's configure script is unable to determine how to change the FPU
3626 precision. On these platforms conversions use the platform strtod and dtoa,
3627 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003628
Georg Brandlba83f822010-03-14 09:50:54 +00003629- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3630 uses the correctly-rounded string <-> float conversions described above (when
3631 available), and so produces correctly rounded results that will display nicely
3632 under the float repr. There are two related small changes: (1) round now
3633 accepts any class with an ``__index__()`` method for its second argument (but
3634 no longer accepts floats for the second argument), and (2) an excessively
3635 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3636 raises an exception.

3639
Georg Brandlba83f822010-03-14 09:50:54 +00003640- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003778
Georg Brandlba83f822010-03-14 09:50:54 +00003779 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3780 (2) parsing of strings representing infinities and nans was locale aware; and
3781 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3784 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3785 but with at least one decimal point and with a default precision
3786 of 12. Previously, the behavior the same but with a default precision of 6.
3787 This more closely matches ``str()``, and reduces surprises when adding
3788 alignment flags to the empty presentation type. This also affects the new
3789 complex.__format__ in the same way.
3790
3791- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5219 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5220 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00005275 leak-chasing test runs give sensible results. The previous method of reaping
5276 threads could return successfully while some Thread objects were still
5277 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandlba83f822010-03-14 09:50:54 +00005279- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00005296 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00005397- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005398 AttributeError instead of RuntimeError, depending in which C API call
5399 exactly the recursion limit is exceeded. Consequently, both exception types
5400 are caught and silenced.

5416
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005417- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5418
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005419- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5420 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5421 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5422 ``printf`` function, whereas PyString_FromFormat has an independent
5423 implementation and uses "%zd" on all platforms for size_t values.
5424 This makes a difference on win64, where ``printf`` needs "%Id" to display
5425 64bit values.
5426
Benjamin Peterson97179b02008-09-09 20:55:01 +00005427- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5428 error.
5429
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005430- Issue #3777: long() applied to a float object now always return a long
5431 object; previously an int would be returned for small values. the __long__
5432 method is allowed to return either an int or a long, but the behaviour of
5433 float objects should not change to respect backward compatibility.
5434
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005435- Issue #3751: str.rpartition would perform a left-partition when called with
5436 a unicode argument.
5437
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005438- Issue #3683: Fix compilation when --without-threads is given.
5439
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005440- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005441 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005442 was correctly parsed but parsing of subsequent arguments failed.
5443
Vinay Sajip35e3b032008-09-01 14:33:59 +00005444- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005445 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5446 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5447 when given a tuple of classes as second argument, were looking up
5448 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5449 type object.
5450
Neal Norwitz18aa3882008-08-24 05:04:52 +00005451- Fix crashes on memory allocation failure found with failmalloc.
5452
5453- Fix memory leaks found with valgrind and update suppressions file.
5454
5455- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5456
5457- Fix problem using wrong name in decimal module reported by pychecker.
5458
Christian Heimes7d4c3172008-08-22 19:47:25 +00005459- Silenced another compiler warning about a used but not defined
5460 function 'stringlib_contains_obj'.

5463 ``__delslice__``.
5464
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005465- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5466 library targets in the Makefile.
5467
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005468- Issue #1204: The configure script now tests for additional libraries
5469 that may be required when linking against readline. This fixes issues
5470 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

5481 stack usage in the case of deeply nested objects.
5482

Nick Coghland2e09382008-09-11 12:11:06 +00005493- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005494 return a list or None rather than a custom object.
5495
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005496- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00005519- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00005520 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5521 for catch_warnings() also led to an improvement in the raising of a
5522 DeprecationWarning related to warnings.warn_explicit().
5523
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005524- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005547- Issue #2975: When compiling several extension modules with Visual Studio 2008
5548 from the same python interpreter, some environment variables would grow
5549 without limit.
5550
Benjamin Peterson37346b22008-08-23 20:27:43 +00005551- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5594-----------------
5595
Guido van Rossumf8402962008-08-20 15:01:50 +00005596- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5597 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5598 extensions do not automatically benefit from the class attribute
5599 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5600 to their tp_flags field if they care. This is a backwards
5601 compatibility feature; in 3.0, all types will use the cache by
5602 default.
5603
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005604- Keyword arguments can now follow starred arguments. (``f(a, *args,
5605 keyword=23)`` is now valid syntax.)
5606
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005607- ctypes function pointers that are COM methods have a boolean True
5608 value again.
5609
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005610- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5611 by denying s# to parse objects that have a releasebuffer procedure,
5612 and introducing s*.
5613
Georg Brandl1e13ea92008-08-11 09:07:59 +00005614- Issue #3537: Fix an assertion failure when an empty but presized dict
5615 object was stored in the freelist.
5616
Mark Dickinsonb6467572008-08-04 21:30:09 +00005617- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5618 ValueError consistently across platforms.
5619
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005620- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5621 (64bit Unix, for example), unichr() would truncate its argument and return
5622 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5623
Neal Norwitze7d8be82008-07-31 17:17:14 +00005624- Apply security patches from Apple.
5625
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005626- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5627 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5628
Antoine Pitrou92f82162008-07-25 22:22:08 +00005629- Issue #1819: function calls with several named parameters are now on
5630 average 35% faster (as measured by pybench).
5631
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005632- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5633 the python debugger steps into a class statement: the free variables (local
5634 variables defined in an outer scope) would be deleted from the outer scope.
5635
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005636- Issue #2620: Overflow checking when allocating or reallocating memory
5637 was not always being done properly in some python types and extension
5638 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5639 all been updated to perform better checks and places in the code that
5640 would previously leak memory on the error path when such an allocation
5641 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005646- Issue #3612: Added some missing basic types in ctypes.wintypes.
5647
Benjamin Petersone977ad42008-08-20 01:42:01 +00005648- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5649 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5650
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005651- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5652 version reported by these tools does not necessarily follow the python
5653 version numbering scheme, so the module is less strict when parsing it.
5654
Nick Coghlanf70385a2008-08-18 12:42:46 +00005655- Issue #2235: Added Py3k warnings for types which will become unhashable
5656 under the stricter __hash__ inheritance rules in 3.0. Several types
5657 which did not meet the rules for hash invariants and were already
5658 unhashable in 3.0 have now been explicitly flagged as unhashable in
5659 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5660 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5661
Brett Cannon88f801d2008-08-18 00:46:22 +00005662- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5663 imported into the module but exposed as part of the module's API.
5664
Brett Cannon7b96f072008-08-18 00:41:11 +00005665- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5666
Brett Cannon46225e72008-08-18 00:36:52 +00005667- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005669- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5670
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005671- Issue #3575: Incremental decoder's decode function now takes bytearray
5672 by using 's*' instead of 't#'.

5775
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005776- Issue #643841: The language reference now provides more detailed

5788-----------------
5789
Georg Brandl3e483f62008-07-16 22:57:41 +00005790- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5791 its methods now allow for items objects that can be converted to
5792 an integer using operator.index().
5793
Mark Dickinson64b7e502008-07-16 09:40:03 +00005794- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5795 produced a ValueError instead of giving the correct float.
5796
Eric Smitha5fa5a22008-07-16 00:11:49 +00005797- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5798 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5799
Mark Dickinson7103aa42008-07-15 19:08:33 +00005800- Issue #3008: the float type has a new instance method 'float.hex'
5801 and a new class method 'float.fromhex' to convert floating-point
5802 numbers to and from hexadecimal strings, respectively.
5803
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005804- Issue #2235: __hash__ is once again inherited by default. To allow
5805 collections.Hashable to remain meaningful in the presence of the
5806 default hash implementation (object.__hash__), it is now possible
5807 to explicit block inheritance of hash by setting __hash__=None at
5808 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5809 level.
5810
Nick Coghlanb028f502008-07-13 14:52:36 +00005811- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5812 the parent module cannot be found while performing an absolute import.
5813 This means that an incorrectly defined __package__ attribute will
5814 now only prevent relative imports in that module rather than causing
5815 all imports from that module to fail.
5816
Nick Coghlan14ff9942008-07-08 14:21:42 +00005817- Issue #2517: Allow unicode messages in Exceptions again by correctly

5827 another thread's dictionary.
5828
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005829- Issue #3004: Minor change to slice.indices(): the start and stop
5830 arguments are now treated identically, making the behaviour easier
5831 to describe and understand. For example, slice(None, -10,
5832 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5833 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5834 10, -1).
5835
Georg Brandl278fc502008-07-19 12:46:12 +00005836- Issue #3219: Calling a function with repeated keyword arguments,
5837 f(a=2, a=23), would not cause a syntax error. This was a regression
5838 from 2.4 caused by the switch to the new compiler.

5848 api functions without holding the GIL, which could lead to a fatal
5849 error when they failed.
5850
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005851- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005876- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5877 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005878 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005879 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005895- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6239 suitable sign) if n is large and negative; previously, it raised
6240 OverflowError.

6287 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006288 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006289
6290 This is controlled by the configure argument ``--with-universal-archs``:
6291
6292 - ``--with-universal-archs=all``: install 4-way universal
6293
6294 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6295
6296 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6297
6298 This option should be used in combination with ``--enable-universalsdk=``.
6299
6300 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 +00006350- Issue #1631171: Re-implement the 'warnings' module in C (the
6351 original Python code has been kept as backup). This will allow for
6352 using the 'warning's machinery in such places as the parser where
6353 use of pure Python code is not possible. Both the ``showarning()``
6354 and ``formatwarning()`` gain an optional 'line' argument which is
6355 not called by default for backwards-compatibility reasons. Setting
6356 ``warnings.showwarning()`` to an implementation that lacks support
6357 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006420- Issue #2550: The approach used by client/server code for obtaining
6421 ports to listen on in network-oriented tests has been refined in an
6422 effort to facilitate running multiple instances of the entire
6423 regression test suite in parallel without issue.
6424 test_support.bind_port() has been fixed such that it will always
6425 return a unique port -- which wasn't always the case with the
6426 previous implementation, especially if socket options had been set
6427 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6428 new implementation of bind_port() will actually raise an exception
6429 if it is passed an AF_INET/SOCK_STREAM socket with either the
6430 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6431 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6432 the socket it's been passed. This currently only applies to
6433 Windows. This option prevents any other sockets from binding to the
6434 host/port we've bound to, thus removing the possibility of the
6435 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6436 when a second SOCK_STREAM socket binds and accepts to a host/port
6437 that's already been bound by another socket. The optional preferred
6438 port parameter to bind_port() has been removed. Under no
6439 circumstances should tests be hard coding ports!
6440
6441 test_support.find_unused_port() has also been introduced, which will
6442 pass a temporary socket object to bind_port() in order to obtain an
6443 unused port. The temporary socket object is then closed and
6444 deleted, and the port is returned. This method should only be used
6445 for obtaining an unused port in order to pass to an external program
6446 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6447 a parameter to a server-oriented class that doesn't give you direct
6448 access to the underlying socket used.
6449
6450 Finally, test_support.HOST has been introduced, which should be used
6451 for the host argument of any relevant socket calls (i.e. bind and
6452 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006453
6454 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006455 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006456 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6457 test_asynchat and test_socket_ssl.
6458
Georg Brandl3ee81df2008-05-17 18:14:43 +00006459 It is now possible for multiple instances of the regression test
6460 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006514- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006515 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6516 Plane. This affected raw unicode literals and the
6517 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6518 this case, like normal unicode literals and the 'unicode-escape'
6519 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006739- Added the future_builtins module, which contains hex() and oct().
6740 These are the PEP 3127 version of these functions, designed to be
6741 compatible with the hex() and oct() builtins from Python 3.0. They
6742 differ slightly in their output formats from the existing, unchanged
6743 Python 2.6 builtins. The expected usage of the future_builtins
6744 module is:
6745 from future_builtins import hex, oct
6746
Eric Smith7ef40bf2008-02-20 23:34:22 +00006747- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6748 exponents for exponents with absolute value < 100. Follows C99
6749 standard. This is a change on Windows, which would use 3 digits.
6750 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6751 so that any alterations it does to the resulting string will be
6752 available in stringlib/formatter.h (for float.__format__).
6753
Eric Smith5a3c1352008-02-19 13:21:56 +00006754- Implemented PEP 3101, Advanced String Formatting. This adds a new
6755 builtin format(); a format() method for str and unicode; a
6756 __format__() method to object, str, unicode, int, long, float, and
6757 datetime; the class string.Formatter; and the C API
6758 PyObject_Format().
6759
Georg Brandl3ee81df2008-05-17 18:14:43 +00006760- Fixed several potential crashes, all caused by specially crafted
6761 __del__ methods exploiting objects in temporarily inconsistent
6762 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006763
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006764- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006765 prevent a possible crash: an Abstract Base Class would try to access
6766 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006767

Georg Brandl3ee81df2008-05-17 18:14:43 +00006771- Clear all free lists during a gc.collect() of the highest generation
6772 in order to allow pymalloc to free more arenas. Python may give back
6773 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006774
Georg Brandl3ee81df2008-05-17 18:14:43 +00006775- Issue #2045: Fix an infinite recursion triggered when printing a
6776 subclass of collections.defaultdict, if its default_factory is set
6777 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006805- Patch #1473257: generator objects gain a gi_code attribute. This is
6806 the same object as the func_code attribute of the function that
6807 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006808
Georg Brandl3ee81df2008-05-17 18:14:43 +00006809- Issue #1920: "while 0" statements were completely removed by the
6810 compiler, even in the presence of an "else" clause, which is
6811 supposed to be run when the condition is false. Now the compiler
6812 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006813
Guido van Rossumeead05f2008-01-24 18:21:02 +00006814- A few crashers fixed: weakref_in_del.py (issue #1377858);
6815 loosing_dict_ref.py (issue #1303614, test67.py);
6816 borrowed_ref_[34].py (not in tracker).
6817
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006818- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006819 suppressed while an extension is loaded by calling SetErrorMode in
6820 dynload_win.c. The error is still reported properly.
6821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006823 several extension methods and modules do not work without unicode
6824 support.
6825
Georg Brandl26543b12008-01-21 18:36:51 +00006826- Issue #1882: when compiling code from a string, encoding cookies in the

6830
Georg Brandl6caad7d2008-01-26 14:19:22 +00006831- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006832 added.
6833
Christian Heimesc94e2b52008-01-14 04:13:37 +00006834- sys.float_info / PyFloat_GetInfo: The floating point information
6835 object was converted from a dict to a specialized structseq object.
6836
Georg Brandl3ee81df2008-05-17 18:14:43 +00006837- Patch #1816: Added sys.flags structseq. It exposes the status of
6838 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Objects/structseq.c: Implemented new structseq representation. The
6841 patch makes structseqs (e.g. the return value of os.stat) more
6842 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006843
Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Patch #1700288: added a type attribute cache that caches method
6845 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006846
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006847- Bug #1776: __import__() no longer accepts filenames on any platform.

6853 envvar and sys.dont_write_bytecode attribute. All these can be set
6854 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Improve some exception messages when Windows fails to load an
6857 extension module. Now we get for example '%1 is not a valid Win32
6858 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006865- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866 and INF. float("nan"), float("inf") and float("-inf") now work on
6867 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006868
Georg Brandl3ee81df2008-05-17 18:14:43 +00006869- Compiler now generates simpler and faster code for dictionary
6870 literals. The oparg for BUILD_MAP now indicates an estimated
6871 dictionary size. There is a new opcode, STORE_MAP, for adding
6872 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006901- Patch #1739468: Directories and zipfiles containing a __main__.py
6902 file can now be directly executed by passing their name to the
6903 interpreter. The directory/zipfile is automatically inserted as the
6904 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006905
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906- Issue #1265: Fix a problem with sys.settrace, if the tracing
6907 function uses a generator expression when at the same time the
6908 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006909
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006910- sets and frozensets now have an isdisjoint() method.
6911
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006912- optimize the performance of builtin.sum().

6915
Georg Brandl21e99f42010-03-07 15:23:59 +00006916- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006917 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6918 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006919
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920- Issue #1686386: Tuple's tp_repr did not take into account the
6921 possibility of having a self-referential tuple, which is possible
6922 from C code. Nor did object's tp_str consider that a type's tp_str
6923 could do something that could lead to an inifinite recursion.
6924 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6925 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006926
Georg Brandl3ee81df2008-05-17 18:14:43 +00006927- Issue #1164: It was possible to trigger deadlock when using the
6928 'print' statement to write to a file since the GIL was not released
6929 as needed. Now PyObject_Print() does the right thing along with
6930 various tp_print implementations of the built-in types and those in
6931 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006932
Georg Brandl3ee81df2008-05-17 18:14:43 +00006933- Issue #1147: Exceptions were directly allowing string exceptions in
6934 their throw() method even though string exceptions no longer
6935 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006936
Georg Brandl3ee81df2008-05-17 18:14:43 +00006937- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00006939
Brett Cannon1e534b52007-09-07 04:18:30 +00006940- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006941 PyObject_Call() never calling back out to Python code to trigger
6942 recursion depth updates/checks. Required the creation of a static
6943 RuntimeError instance in case normalizing an exception put the
6944 recursion check value past its limit. Fixes crashers
6945 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006946

Neal Norwitz0ac60192007-05-27 04:08:54 +00006960- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006961 __*__ attributes. (Some already existed, e.g., __doc__ and
6962 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006963
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006964- Add -3 option to the interpreter to warn about features that are

6966
Georg Brandl2134e752007-05-21 20:34:16 +00006967- Patch #1686487: you can now pass any mapping after '**' in function
6968 calls.
6969
Collin Winter62903052007-05-18 23:11:24 +00006970- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971 "except E as target:". This is to provide forwards compatibility
6972 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006976- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006977 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006978
Vinay Sajip8549ce32007-05-06 17:53:37 +00006979- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006980 setting a plain string, ie don't expand to single letter identifiers.
6981
Raymond Hettinger13936692007-04-11 18:40:58 +00006982- Request #1191699: Slices can now be pickled.
6983
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006984- Request #1193128: str.translate() now allows a None argument for
6985 translations that only remove characters without re-mapping the
6986 remaining characters.
6987
Georg Brandl5cb76c12007-03-21 09:00:39 +00006988- Patch #1682205: a TypeError while unpacking an iterable is no longer

6992
Guido van Rossum143b5642007-03-23 04:58:42 +00006993- Bug #1683368: The object.__init__() and object.__new__() methods are
6994 now stricter in rejecting excess arguments. The only time when
6995 either allows excess arguments is when it is not overridden and the
6996 other one is. For backwards compatibility, when both are
6997 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006998 warning later). Also, type.__init__() insists on the same signature
6999 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007001- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7002 object to complex using its __complex__() method before falling back
7003 to the __float__() method. Therefore, the functions in the cmath
7004 module now can operate on objects that define a __complex__()
7005 method.

7025
Georg Brandl871f1bc2007-03-12 13:17:36 +00007026- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007027 its argument, if it exists. If not, it will work like before. This
7028 allows customizing the output of dir() in the presence of a
7029 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007041- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007042 makes the filenames the warning module prints much more sensible
7043 when a PYTHONSTARTUP file is used.

7058
Georg Brandl3ee81df2008-05-17 18:14:43 +00007059- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00007111- Bug #1545497: when given an explicit base, int() did ignore NULs
7112 embedded in the string to convert.
7113
Georg Brandl846f73a2006-10-08 07:11:54 +00007114- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007162 generator expressions (x for x, in ... ) works again. Fixing this
7163 problem required changing the .pyc magic number. This means that
7164 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- The implementation of UnicodeError objects has been simplified
7968 (start and end attributes are now stored directly as Py_ssize_t
7969 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007970
Georg Brandl3ee81df2008-05-17 18:14:43 +00007971- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7972 with RFC 3207 and forgets any knowledge obtained from the server not
7973 obtained from the TLS negotiation itself. Patch contributed by Bill
7974 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007975
Georg Brandl3ee81df2008-05-17 18:14:43 +00007976- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007977 that the SMTP.starttls() caller no longer needs to call ehlo()
7978 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979 does not claim to support starttls. Adds the
7980 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7981 Fenner.

8061 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8062 silently miscode subclasses of those types. Now, it raises a
8063 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008064

Georg Brandl3ee81df2008-05-17 18:14:43 +00008079 time so that opening a database previously created with the DB_DUP
8080 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8081 opens. Specifically: dictionary assignment to a DB object will
8082 replace all values for a given key when the database allows
8083 duplicate values. DB users should use DB.put(k, v) when they want
8084 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008085

8091 characters with ASCII value less than 32. Also, it correctly quotes
8092 dots only if they occur on a single line, as opposed to the previous
8093 behavior of quoting dots if they are the second character of any
8094 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008095
