589
590- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
591 and later systems as is currently done for Python 3.x installers.
592 For 2.7.7 only, we will provide three installers:
593 the legacy deprecated 10.3+ 32-bit-only format;
594 the newer 10.5+ 32-bit-only format;
595 and the unchanged 10.6+ 64-/32-bit format.
596 Although binary installers will no longer be available from
597 python.org as of 2.7.8, it will still be possible to build from
598 source on 10.3.9 and 10.4 systems if necessary.

929 options like -fwrapv were overridden and thus not used, which could result
930 in broken interpreters when building with clang.

1978 32-bit-only installer Pythons on systems with Xcode 4 (currently
1979 OS X 10.8, 10.7, and optionally 10.6).
1980 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1981 * Since Xcode 4 removes ppc support, extension module builds now
1982 check for ppc compiler support and by default remove ppc and
1983 ppc64 archs when they are not available.
1984 * Extension module builds now revert to using system installed
1985 headers and libs (/usr and /System/Library) if the SDK used
1986 to build the interpreter is not installed or has moved.
1987 * Try to avoid building extension modules with deprecated
1988 and problematic Apple llvm-gcc compiler. If original compiler
1989 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002340- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2341 int.__pow__. These overflow checks were causing int.__pow__ to produce
2342 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002343 compiler optimizing the check away. Also fix similar overflow checks
2344 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2345 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002413- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002414 has left two versions of customize_compiler, the original in
2415 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002420- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2421 Distutils-based packages with C extension modules may fail because
2422 Apple has removed gcc-4.2, the version used to build python.org
2423 64-bit/32-bit Pythons. If the user does not explicitly override
2424 the default C compiler by setting the CC environment variable,
2425 Distutils will now attempt to compile extension modules with clang
2426 if gcc-4.2 is required but not found. Also as a convenience, if
2427 the user does explicitly set CC, substitute its value as the default
2428 compiler in the Distutils LDSHARED configuration variable for OS X.
2429 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2430 SDK, neither of which are available in Xcode 4. This change does not
2431 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002681- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2682 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2683 interpreter process. This could cause failures in non-Distutils subprocesses
2684 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002685 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002686 deployment target only in the environment of each build subprocess. It is
2687 still possible to globally override the default by setting
2688 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2689 greater or equal to the default value, the value with which the interpreter
2690 was built.

2720 the ticker doesn't have to wind down to zero from the old starting point
2721 before the new interval takes effect. And if the user increases the
2722 interval, it makes sure the new limit takes effect right away rather have an

3702
Raymond Hettinger20397532010-09-12 02:11:45 +00003703- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3704 This prevents user-created self-referencing ordered dictionaries from
3705 becoming permanently uncollectable GC garbage. The downside is that
3706 removing __del__ means that the internal doubly-linked list has to wait for
3707 GC collection rather than freeing memory immediately when the refcnt drops
3708 to zero.

3713
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003714- Issue #9792: In case of connection failure, socket.create_connection()

3716 to fetch the original errno, or to filter timeout errors. Now the
3717 original error is re-raised.

4165
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004166- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4167 start byte and the continuation byte(s) are now considered invalid, instead
4168 of the number of bytes specified by the start byte.
4169 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4170 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4171 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4172 Previous versions returned a single u'\ufffd'.

4178 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004180- Issue #8748: Fix two issues with comparisons between complex and integer
4181 objects. (1) The comparison could incorrectly return True in some cases
4182 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4183 (2) The comparison raised an OverflowError for large integers, leading
4184 to unpredictable exceptions when combining integers and complex objects
4185 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004187- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00005065 file position when calling `truncate()`. It would previously change the file
5066 position to the given argument, which goes against the tradition of

5070 class used to represent files stored inside an archive. The new
5071 implementation is significantly faster and can be wrapped in a
5072 ``io.BufferedReader`` object for more speedups. It also solves an issue
5073 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5162-----------------
5163
Georg Brandlba83f822010-03-14 09:50:54 +00005164- The ``__complex__()`` method is now looked up on the class of instances to
5165 make it consistent with other special methods.

5169
Mark Dickinson1b34d252010-01-01 17:27:30 +00005170- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005171 DeprecationWarning when passed a float argument where an integer was expected.
5172 These functions and methods now raise TypeError instead. The majority of the
5173 effects of this change are in the extension modules, but some core functions
5174 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5175 and many unicode/str methods.

5189 of integers: the result of a/b is now correctly rounded for ints a and b (at
5190 least on IEEE 754 platforms), and in particular does not depend on the
5191 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005200 These executables now work properly with the arch(1) command: ``arch -ppc

5287 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5288 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5289 float arguments for integer format codes (other than 'L'): previously an
5290 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5291 TypeError. For the 'L' format code (which previously had no warning) there is
5292 now a DeprecationWarning.

5341 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005342
Georg Brandlba83f822010-03-14 09:50:54 +00005343- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5344 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005345
Georg Brandlba83f822010-03-14 09:50:54 +00005346- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5347 1e-100 used to raise OverflowError, but now gives the requested 120
5348 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005356
Georg Brandlba83f822010-03-14 09:50:54 +00005357- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5358 decimal string that's guaranteed to round back to x under correct rounding
5359 (with round-half-to-even rounding mode). Previously it gave a string based on
5360 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5361 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5362 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005363
Georg Brandlba83f822010-03-14 09:50:54 +00005364- Issue #7117: On almost all platforms: float-to-string and string-to-float
5365 conversions within Python are now correctly rounded. Places these conversions
5366 occur include: str for floats and complex numbers; the float and complex
5367 constructors; old-style and new-style numeric formatting; serialization and
5368 deserialization of floats and complex numbers using marshal, pickle and json;
5369 parsing of float and imaginary literals in Python code; Decimal-to-float
5370 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005371
Georg Brandlba83f822010-03-14 09:50:54 +00005372 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5373 providing correctly-rounded strtod and dtoa C functions. This code is
5374 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5375 the C compiler. There may be a small number of platforms on which correct
5376 operation of this code cannot be guaranteed, so the code is not used: notably,
5377 this applies to platforms where the C double format is not IEEE 754 binary64,
5378 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5379 and Python's configure script is unable to determine how to change the FPU
5380 precision. On these platforms conversions use the platform strtod and dtoa,
5381 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005382
Georg Brandlba83f822010-03-14 09:50:54 +00005383- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5384 uses the correctly-rounded string <-> float conversions described above (when
5385 available), and so produces correctly rounded results that will display nicely
5386 under the float repr. There are two related small changes: (1) round now
5387 accepts any class with an ``__index__()`` method for its second argument (but
5388 no longer accepts floats for the second argument), and (2) an excessively
5389 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5390 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005520- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5521 consistent with float("1e500") and interpretation of real and imaginary
5522 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005531- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005532
Georg Brandlba83f822010-03-14 09:50:54 +00005533 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5534 (2) parsing of strings representing infinities and nans was locale aware; and
5535 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005536
Georg Brandlba83f822010-03-14 09:50:54 +00005537- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5538 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5539 but with at least one decimal point and with a default precision
5540 of 12. Previously, the behavior the same but with a default precision of 6.
5541 This more closely matches ``str()``, and reduces surprises when adding
5542 alignment flags to the empty presentation type. This also affects the new
5543 complex.__format__ in the same way.
5544
5545- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5546 classtype's, even if it was None. property now inserts the __doc__ into the
5547 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005607- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005608 untrackable objects are not tracked by the garbage collector. This can reduce
5609 the size of collections and therefore the garbage collection overhead on

5617 internal representation of integers, for performance reasons. Base 2**30 is
5618 enabled by default on 64-bit machines. Add --enable-big-digits option to
5619 configure, which overrides the default. Add sys.long_info structseq to
5620 provide information about the internal format.

5769 this code path is really executed because I cannot move to such directory on

5774 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005795- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5796 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5797 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5798 of using the replace error handler in PyUnicode_DecodeUTF8().
5799
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005800- Issue #3739: The unicode-internal encoder now reports the number of characters

5802
Georg Brandlba83f822010-03-14 09:50:54 +00005803- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5805 gives improved memory leak detection when running under Valgrind, while taking
5806 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007174- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7175
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007176- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7177 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7178 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7179 ``printf`` function, whereas PyString_FromFormat has an independent
7180 implementation and uses "%zd" on all platforms for size_t values.
7181 This makes a difference on win64, where ``printf`` needs "%Id" to display
7182 64bit values.
7183
Benjamin Peterson97179b02008-09-09 20:55:01 +00007184- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7185 error.
7186
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007187- Issue #3777: long() applied to a float object now always return a long
7188 object; previously an int would be returned for small values. the __long__
7189 method is allowed to return either an int or a long, but the behaviour of
7190 float objects should not change to respect backward compatibility.
7191
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007192- Issue #3751: str.rpartition would perform a left-partition when called with
7193 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007198 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007199 was correctly parsed but parsing of subsequent arguments failed.
7200
Vinay Sajip35e3b032008-09-01 14:33:59 +00007201- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007202 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7203 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7204 when given a tuple of classes as second argument, were looking up
7205 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7206 type object.
7207
Neal Norwitz18aa3882008-08-24 05:04:52 +00007208- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007277 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7278 for catch_warnings() also led to an improvement in the raising of a

7351-----------------
7352
Guido van Rossumf8402962008-08-20 15:01:50 +00007353- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7354 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7355 extensions do not automatically benefit from the class attribute
7356 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7357 to their tp_flags field if they care. This is a backwards
7358 compatibility feature; in 3.0, all types will use the cache by
7359 default.
7360
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007361- Keyword arguments can now follow starred arguments. (``f(a, *args,
7362 keyword=23)`` is now valid syntax.)
7363
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007364- ctypes function pointers that are COM methods have a boolean True
7365 value again.
7366
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007367- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7368 by denying s# to parse objects that have a releasebuffer procedure,
7369 and introducing s*.
7370
Georg Brandl1e13ea92008-08-11 09:07:59 +00007371- Issue #3537: Fix an assertion failure when an empty but presized dict
7372 object was stored in the freelist.
7373
Mark Dickinsonb6467572008-08-04 21:30:09 +00007374- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7375 ValueError consistently across platforms.
7376
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007377- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7378 (64bit Unix, for example), unichr() would truncate its argument and return
7379 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7380
Neal Norwitze7d8be82008-07-31 17:17:14 +00007381- Apply security patches from Apple.
7382
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007383- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7384 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7385
Antoine Pitrou92f82162008-07-25 22:22:08 +00007386- Issue #1819: function calls with several named parameters are now on
7387 average 35% faster (as measured by pybench).
7388
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007389- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7390 the python debugger steps into a class statement: the free variables (local
7391 variables defined in an outer scope) would be deleted from the outer scope.
7392
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007393- Issue #2620: Overflow checking when allocating or reallocating memory
7394 was not always being done properly in some python types and extension
7395 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7396 all been updated to perform better checks and places in the code that
7397 would previously leak memory on the error path when such an allocation
7398 failed have been fixed.

7404
Benjamin Petersone977ad42008-08-20 01:42:01 +00007405- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7406 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7407
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007408- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7409 version reported by these tools does not necessarily follow the python

7411
Nick Coghlanf70385a2008-08-18 12:42:46 +00007412- Issue #2235: Added Py3k warnings for types which will become unhashable
7413 under the stricter __hash__ inheritance rules in 3.0. Several types
7414 which did not meet the rules for hash invariants and were already
7415 unhashable in 3.0 have now been explicitly flagged as unhashable in
7416 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7417 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7418
Brett Cannon88f801d2008-08-18 00:46:22 +00007419- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7474 the reload() built-in has been removed.
7475
Brett Cannon7e30b672008-08-04 21:52:25 +00007476- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007488 asking for a specific length. This problem only affected files opened
7489 using the new "io" module, not the built-in open() function.

7515 file name rather than a ZipInfo instance, so files are extracted with
7516 mode 0600 rather than 000 under Unix.
7517
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007518- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

7531 interaction with the tp_hash slot (added in 2.6b2) are now documented
7532
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007533- Issue #643841: The language reference now provides more detailed
7534 coverage of the lookup process for special methods. The disclaimers
7535 regarding lack of coverage of new-style classes have also been
7536 removed, since the coverage is now fairly reasonable.

7540================================
7541
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007542*Release date: 17-Jul-2008*
7543
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007544Core and Builtins
7545-----------------
7546
Georg Brandl3e483f62008-07-16 22:57:41 +00007547- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7548 its methods now allow for items objects that can be converted to
7549 an integer using operator.index().
7550
Mark Dickinson64b7e502008-07-16 09:40:03 +00007551- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7552 produced a ValueError instead of giving the correct float.
7553
Eric Smitha5fa5a22008-07-16 00:11:49 +00007554- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7555 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7556
Mark Dickinson7103aa42008-07-15 19:08:33 +00007557- Issue #3008: the float type has a new instance method 'float.hex'
7558 and a new class method 'float.fromhex' to convert floating-point
7559 numbers to and from hexadecimal strings, respectively.
7560
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007561- Issue #2235: __hash__ is once again inherited by default. To allow
7562 collections.Hashable to remain meaningful in the presence of the
7563 default hash implementation (object.__hash__), it is now possible
7564 to explicit block inheritance of hash by setting __hash__=None at
7565 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7566 level.
7567
Nick Coghlanb028f502008-07-13 14:52:36 +00007568- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7569 the parent module cannot be found while performing an absolute import.
7570 This means that an incorrectly defined __package__ attribute will
7571 now only prevent relative imports in that module rather than causing
7572 all imports from that module to fail.
7573
Nick Coghlan14ff9942008-07-08 14:21:42 +00007574- Issue #2517: Allow unicode messages in Exceptions again by correctly
7575 bypassing the instance dictionary when looking up __unicode__ on
7576 new-style classes.
7577
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007578- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7579 set to a custom object whose write() method happens to install
7580 another file in sys.stdout.
7581
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007582- Issue #3088: Corrected a race condition in classes derived from
7583 threading.local: the first member set by a thread could be saved in
7584 another thread's dictionary.
7585
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007586- Issue #3004: Minor change to slice.indices(): the start and stop
7587 arguments are now treated identically, making the behaviour easier
7588 to describe and understand. For example, slice(None, -10,
7589 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7590 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7591 10, -1).
7592
Georg Brandl278fc502008-07-19 12:46:12 +00007593- Issue #3219: Calling a function with repeated keyword arguments,
7594 f(a=2, a=23), would not cause a syntax error. This was a regression
7595 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007596
Georg Brandl278fc502008-07-19 12:46:12 +00007597- Issue #2862: Make int and float freelist management consistent with
7598 other freelists. Changes their CompactFreeList apis into
7599 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007604- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7605 api functions without holding the GIL, which could lead to a fatal
7606 error when they failed.
7607
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007608- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007633- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7634 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007635 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007636 content-length. The problem had been corrected in the 2.4 branch, but never
7637 merged into trunk.
7638

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007652- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7654
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007655- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7656 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00008041- On MacOS X it is now possible to install the framework in 64-bit
8042 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008043 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008044
8045 This is controlled by the configure argument ``--with-universal-archs``:
8046
8047 - ``--with-universal-archs=all``: install 4-way universal
8048
8049 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8050
8051 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8052
8053 This option should be used in combination with ``--enable-universalsdk=``.
8054
8055 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 +00008104- Issue #1631171: Re-implement the 'warnings' module in C (the
8105 original Python code has been kept as backup). This will allow for
8106 using the 'warning's machinery in such places as the parser where
8107 use of pure Python code is not possible. Both the ``showarning()``
8108 and ``formatwarning()`` gain an optional 'line' argument which is
8109 not called by default for backwards-compatibility reasons. Setting
8110 ``warnings.showwarning()`` to an implementation that lacks support
8111 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008174- Issue #2550: The approach used by client/server code for obtaining
8175 ports to listen on in network-oriented tests has been refined in an
8176 effort to facilitate running multiple instances of the entire
8177 regression test suite in parallel without issue.
8178 test_support.bind_port() has been fixed such that it will always
8179 return a unique port -- which wasn't always the case with the
8180 previous implementation, especially if socket options had been set
8181 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8182 new implementation of bind_port() will actually raise an exception
8183 if it is passed an AF_INET/SOCK_STREAM socket with either the
8184 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8185 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8186 the socket it's been passed. This currently only applies to
8187 Windows. This option prevents any other sockets from binding to the
8188 host/port we've bound to, thus removing the possibility of the
8189 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8190 when a second SOCK_STREAM socket binds and accepts to a host/port
8191 that's already been bound by another socket. The optional preferred
8192 port parameter to bind_port() has been removed. Under no
8193 circumstances should tests be hard coding ports!
8194
8195 test_support.find_unused_port() has also been introduced, which will
8196 pass a temporary socket object to bind_port() in order to obtain an
8197 unused port. The temporary socket object is then closed and
8198 deleted, and the port is returned. This method should only be used
8199 for obtaining an unused port in order to pass to an external program
8200 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8201 a parameter to a server-oriented class that doesn't give you direct
8202 access to the underlying socket used.
8203
8204 Finally, test_support.HOST has been introduced, which should be used
8205 for the host argument of any relevant socket calls (i.e. bind and
8206 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008207
8208 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008209 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008210 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8211 test_asynchat and test_socket_ssl.
8212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213 It is now possible for multiple instances of the regression test
8214 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00008268- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269 \Uxxxxxxxx did not accept values outside the Basic Multilingual
8270 Plane. This affected raw unicode literals and the
8271 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8272 this case, like normal unicode literals and the 'unicode-escape'
8273 codec.

8496 differ slightly in their output formats from the existing, unchanged
8497 Python 2.6 builtins. The expected usage of the future_builtins
8498 module is:
8499 from future_builtins import hex, oct
8500
Eric Smith7ef40bf2008-02-20 23:34:22 +00008501- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8502 exponents for exponents with absolute value < 100. Follows C99
8503 standard. This is a change on Windows, which would use 3 digits.
8504 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8505 so that any alterations it does to the resulting string will be
8506 available in stringlib/formatter.h (for float.__format__).
8507
Eric Smith5a3c1352008-02-19 13:21:56 +00008508- Implemented PEP 3101, Advanced String Formatting. This adds a new
8509 builtin format(); a format() method for str and unicode; a
8510 __format__() method to object, str, unicode, int, long, float, and
8511 datetime; the class string.Formatter; and the C API
8512 PyObject_Format().
8513
Georg Brandl3ee81df2008-05-17 18:14:43 +00008514- Fixed several potential crashes, all caused by specially crafted
8515 __del__ methods exploiting objects in temporarily inconsistent
8516 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008525- Clear all free lists during a gc.collect() of the highest generation
8526 in order to allow pymalloc to free more arenas. Python may give back
8527 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008528
Georg Brandl3ee81df2008-05-17 18:14:43 +00008529- Issue #2045: Fix an infinite recursion triggered when printing a
8530 subclass of collections.defaultdict, if its default_factory is set
8531 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008559- Patch #1473257: generator objects gain a gi_code attribute. This is
8560 the same object as the func_code attribute of the function that
8561 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008562
Georg Brandl3ee81df2008-05-17 18:14:43 +00008563- Issue #1920: "while 0" statements were completely removed by the
8564 compiler, even in the presence of an "else" clause, which is
8565 supposed to be run when the condition is false. Now the compiler
8566 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008567
Guido van Rossumeead05f2008-01-24 18:21:02 +00008568- A few crashers fixed: weakref_in_del.py (issue #1377858);

8575
Georg Brandl3ee81df2008-05-17 18:14:43 +00008576- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008577 several extension methods and modules do not work without unicode
8578 support.
8579
Georg Brandl26543b12008-01-21 18:36:51 +00008580- Issue #1882: when compiling code from a string, encoding cookies in the

8584
Georg Brandl6caad7d2008-01-26 14:19:22 +00008585- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008586 added.
8587
Christian Heimesc94e2b52008-01-14 04:13:37 +00008588- sys.float_info / PyFloat_GetInfo: The floating point information
8589 object was converted from a dict to a specialized structseq object.
8590
Georg Brandl3ee81df2008-05-17 18:14:43 +00008591- Patch #1816: Added sys.flags structseq. It exposes the status of
8592 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008593
Georg Brandl3ee81df2008-05-17 18:14:43 +00008594- Objects/structseq.c: Implemented new structseq representation. The
8595 patch makes structseqs (e.g. the return value of os.stat) more
8596 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008597
Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Patch #1700288: added a type attribute cache that caches method
8599 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008600
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008601- Bug #1776: __import__() no longer accepts filenames on any platform.

8608 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008609
Georg Brandl3ee81df2008-05-17 18:14:43 +00008610- Improve some exception messages when Windows fails to load an
8611 extension module. Now we get for example '%1 is not a valid Win32
8612 application' instead of 'error code 193'.

8669
Georg Brandl21e99f42010-03-07 15:23:59 +00008670- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008671 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8672 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008673
Georg Brandl3ee81df2008-05-17 18:14:43 +00008674- Issue #1686386: Tuple's tp_repr did not take into account the
8675 possibility of having a self-referential tuple, which is possible
8676 from C code. Nor did object's tp_str consider that a type's tp_str
8677 could do something that could lead to an inifinite recursion.
8678 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8679 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008680
Georg Brandl3ee81df2008-05-17 18:14:43 +00008681- Issue #1164: It was possible to trigger deadlock when using the
8682 'print' statement to write to a file since the GIL was not released
8683 as needed. Now PyObject_Print() does the right thing along with
8684 various tp_print implementations of the built-in types and those in
8685 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008695 PyObject_Call() never calling back out to Python code to trigger
8696 recursion depth updates/checks. Required the creation of a static

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008738- Request #1193128: str.translate() now allows a None argument for
8739 translations that only remove characters without re-mapping the
8740 remaining characters.
8741
Georg Brandl5cb76c12007-03-21 09:00:39 +00008742- Patch #1682205: a TypeError while unpacking an iterable is no longer
8743 masked by a generic one with the message "unpack non-sequence".

8746
Guido van Rossum143b5642007-03-23 04:58:42 +00008747- Bug #1683368: The object.__init__() and object.__new__() methods are
8748 now stricter in rejecting excess arguments. The only time when
8749 either allows excess arguments is when it is not overridden and the
8750 other one is. For backwards compatibility, when both are
8751 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008752 warning later). Also, type.__init__() insists on the same signature
8753 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008755- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8756 object to complex using its __complex__() method before falling back
8757 to the __float__() method. Therefore, the functions in the cmath
8758 module now can operate on objects that define a __complex__()
8759 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008777- Bug #1678647: write a newline after printing an exception in any
8778 case, even when converting the value to a string failed.
8779
Georg Brandl871f1bc2007-03-12 13:17:36 +00008780- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008781 its argument, if it exists. If not, it will work like before. This
8782 allows customizing the output of dir() in the presence of a
8783 __getattr__().

8793 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008794
Georg Brandlaa2321b2007-03-07 00:40:28 +00008795- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008796 makes the filenames the warning module prints much more sensible
8797 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008798

Georg Brandl0fca97a2007-03-05 22:28:08 +00008810- Patch #1674228: when assigning a slice (old-style), check for the
8811 sq_ass_slice instead of the sq_slice slot.
8812
Georg Brandl3ee81df2008-05-17 18:14:43 +00008813- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008865- Bug #1545497: when given an explicit base, int() did ignore NULs
8866 embedded in the string to convert.
8867
Georg Brandl846f73a2006-10-08 07:11:54 +00008868- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008898- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008916 generator expressions (x for x, in ... ) works again. Fixing this
8917 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00008956- Removed uses of dict.has_key() from distutils, and uses of
8957 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00009714- The implementation of UnicodeError objects has been simplified
9715 (start and end attributes are now stored directly as Py_ssize_t
9716 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009718- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9719 with RFC 3207 and forgets any knowledge obtained from the server not
9720 obtained from the TLS negotiation itself. Patch contributed by Bill
9721 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009722
Georg Brandl3ee81df2008-05-17 18:14:43 +00009723- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009724 that the SMTP.starttls() caller no longer needs to call ehlo()
9725 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009726 does not claim to support starttls. Adds the
9727 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9728 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009770- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009771 works as expected. ``mmap.find`` also takes an optional ``end``
9772 parameter.

9797 contents before adding elements from the iterable. This fix brings
9798 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009799
Georg Brandl3ee81df2008-05-17 18:14:43 +00009800- Added wide char functions to msvcrt module: getwch, getwche, putwch

9806
Georg Brandl3ee81df2008-05-17 18:14:43 +00009807- Marshal.dumps() now expects exact type matches for int, long, float,
9808 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9809 silently miscode subclasses of those types. Now, it raises a
9810 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009811

Georg Brandl3ee81df2008-05-17 18:14:43 +00009826 time so that opening a database previously created with the DB_DUP
9827 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9828 opens. Specifically: dictionary assignment to a DB object will
9829 replace all values for a given key when the database allows
9830 duplicate values. DB users should use DB.put(k, v) when they want
9831 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009832

9838 characters with ASCII value less than 32. Also, it correctly quotes
9839 dots only if they occur on a single line, as opposed to the previous
9840 behavior of quoting dots if they are the second character of any
9841 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009842

9871 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009872

Georg Brandl3ee81df2008-05-17 18:14:43 +000010250- Removed the macfs module. It had been deprecated since Python 2.5.
10251 This lead to the deprecation of macostools.touched() as it relied
10252 solely on macfs and was a no-op under OS X.
