622
623- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
624 and later systems as is currently done for Python 3.x installers.
625 For 2.7.7 only, we will provide three installers:
626 the legacy deprecated 10.3+ 32-bit-only format;
627 the newer 10.5+ 32-bit-only format;
628 and the unchanged 10.6+ 64-/32-bit format.
629 Although binary installers will no longer be available from
630 python.org as of 2.7.8, it will still be possible to build from
631 source on 10.3.9 and 10.4 systems if necessary.
632 See Mac/BuildScript/README.txt for more information.

R David Murray20101872012-08-31 23:15:28 -04001749- Issue #12776,#11839: call argparse type function (specified by add_argument)
1750 only once. Before, the type function was called twice in the case where the
1751 default was specified and the argument was given as well. This was
1752 especially problematic for the FileType type, as a default file would always
1753 be opened, even if a file argument was specified on the command line.

2011 32-bit-only installer Pythons on systems with Xcode 4 (currently
2012 OS X 10.8, 10.7, and optionally 10.6).
2013 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2014 * Since Xcode 4 removes ppc support, extension module builds now
2015 check for ppc compiler support and by default remove ppc and
2016 ppc64 archs when they are not available.
2017 * Extension module builds now revert to using system installed
2018 headers and libs (/usr and /System/Library) if the SDK used
2019 to build the interpreter is not installed or has moved.
2020 * Try to avoid building extension modules with deprecated
2021 and problematic Apple llvm-gcc compiler. If original compiler
2022 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002373- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2374 int.__pow__. These overflow checks were causing int.__pow__ to produce
2375 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002376 compiler optimizing the check away. Also fix similar overflow checks
2377 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2378 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002446- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002447 has left two versions of customize_compiler, the original in
2448 distutils.sysconfig and another copy in distutils.ccompiler, with some

2451 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002453- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2454 Distutils-based packages with C extension modules may fail because
2455 Apple has removed gcc-4.2, the version used to build python.org
2456 64-bit/32-bit Pythons. If the user does not explicitly override
2457 the default C compiler by setting the CC environment variable,
2458 Distutils will now attempt to compile extension modules with clang
2459 if gcc-4.2 is required but not found. Also as a convenience, if
2460 the user does explicitly set CC, substitute its value as the default
2461 compiler in the Distutils LDSHARED configuration variable for OS X.
2462 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2463 SDK, neither of which are available in Xcode 4. This change does not
2464 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002714- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2715 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2716 interpreter process. This could cause failures in non-Distutils subprocesses
2717 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002718 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002719 deployment target only in the environment of each build subprocess. It is
2720 still possible to globally override the default by setting
2721 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2722 greater or equal to the default value, the value with which the interpreter
2723 was built.

2753 the ticker doesn't have to wind down to zero from the old starting point
2754 before the new interval takes effect. And if the user increases the
2755 interval, it makes sure the new limit takes effect right away rather have an
2756 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003736- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3737 This prevents user-created self-referencing ordered dictionaries from
3738 becoming permanently uncollectable GC garbage. The downside is that
3739 removing __del__ means that the internal doubly-linked list has to wait for
3740 GC collection rather than freeing memory immediately when the refcnt drops
3741 to zero.

3750 original error is re-raised.

4198
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004199- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4200 start byte and the continuation byte(s) are now considered invalid, instead
4201 of the number of bytes specified by the start byte.
4202 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4203 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4204 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4205 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004213- Issue #8748: Fix two issues with comparisons between complex and integer
4214 objects. (1) The comparison could incorrectly return True in some cases
4215 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4216 (2) The comparison raised an OverflowError for large integers, leading
4217 to unpredictable exceptions when combining integers and complex objects
4218 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004220- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004357- Issue #1533: Fix inconsistency in range function argument processing: any
4358 non-float non-integer argument is now converted to an integer (if possible)
4359 using its __int__ method. Previously, only small arguments were treated this
4360 way; larger arguments (those whose __int__ was outside the range of a C long)
4361 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004411- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4412 operation raises multiple signals and more than one of those signals is
4413 trapped, the specification determines the order in which the signals should be
4414 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004600- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4601 with a non-empty format string. This is an effort to future-proof user
4602 code. If a derived class does not currently implement __format__ but later
4603 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004604 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004605 Python 3.3 and it will be an error in Python 3.4.

5057 numeric strings corresponding to subnormal values,
5058 (3) a memory leak for some values large enough to cause overflow, and
5059 (4) a number of flaws that could lead to incorrectly rounded results.

5194Core and Builtins
5195-----------------
5196
Georg Brandlba83f822010-03-14 09:50:54 +00005197- The ``__complex__()`` method is now looked up on the class of instances to
5198 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005200- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5202
Mark Dickinson1b34d252010-01-01 17:27:30 +00005203- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005204 DeprecationWarning when passed a float argument where an integer was expected.
5205 These functions and methods now raise TypeError instead. The majority of the
5206 effects of this change are in the extension modules, but some core functions
5207 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5208 and many unicode/str methods.

5219 used to drop the time part of the result.
5220
Georg Brandlba83f822010-03-14 09:50:54 +00005221- Issue #1811: Improve accuracy and cross-platform consistency for true division
5222 of integers: the result of a/b is now correctly rounded for ints a and b (at
5223 least on IEEE 754 platforms), and in particular does not depend on the
5224 internal representation of a long.

5232
Georg Brandlba83f822010-03-14 09:50:54 +00005233 These executables now work properly with the arch(1) command: ``arch -ppc
5234 python`` will start a universal binary version of python in PPC mode (unlike

5374 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005375

Georg Brandlba83f822010-03-14 09:50:54 +00005390- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5391 decimal string that's guaranteed to round back to x under correct rounding
5392 (with round-half-to-even rounding mode). Previously it gave a string based on
5393 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5394 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5395 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005396
Georg Brandlba83f822010-03-14 09:50:54 +00005397- Issue #7117: On almost all platforms: float-to-string and string-to-float
5398 conversions within Python are now correctly rounded. Places these conversions
5399 occur include: str for floats and complex numbers; the float and complex
5400 constructors; old-style and new-style numeric formatting; serialization and
5401 deserialization of floats and complex numbers using marshal, pickle and json;
5402 parsing of float and imaginary literals in Python code; Decimal-to-float
5403 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005404
Georg Brandlba83f822010-03-14 09:50:54 +00005405 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5406 providing correctly-rounded strtod and dtoa C functions. This code is
5407 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5408 the C compiler. There may be a small number of platforms on which correct
5409 operation of this code cannot be guaranteed, so the code is not used: notably,
5410 this applies to platforms where the C double format is not IEEE 754 binary64,
5411 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5412 and Python's configure script is unable to determine how to change the FPU
5413 precision. On these platforms conversions use the platform strtod and dtoa,
5414 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005416- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5417 uses the correctly-rounded string <-> float conversions described above (when
5418 available), and so produces correctly rounded results that will display nicely
5419 under the float repr. There are two related small changes: (1) round now
5420 accepts any class with an ``__index__()`` method for its second argument (but
5421 no longer accepts floats for the second argument), and (2) an excessively
5422 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5423 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005565
Georg Brandlba83f822010-03-14 09:50:54 +00005566 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5567 (2) parsing of strings representing infinities and nans was locale aware; and
5568 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005570- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5571 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5572 but with at least one decimal point and with a default precision
5573 of 12. Previously, the behavior the same but with a default precision of 6.
5574 This more closely matches ``str()``, and reduces surprises when adding
5575 alignment flags to the empty presentation type. This also affects the new
5576 complex.__format__ in the same way.
5577
5578- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5579 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00005641 untrackable objects are not tracked by the garbage collector. This can reduce

5650 internal representation of integers, for performance reasons. Base 2**30 is
5651 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005759- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5760 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5761 instances. On a typical machine this saves 3 bytes of memory (on average) per
5762 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005764- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

5766 instead of throwing a MemoryError.
5767
Georg Brandlba83f822010-03-14 09:50:54 +00005768- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5773
Georg Brandlba83f822010-03-14 09:50:54 +00005774- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5775 file objects with closefd=False. The file descriptor is still kept open but
5776 the file object behaves like a closed file. The ``FileIO`` object also got a
5777 new readonly attribute ``closefd``.

5796
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005797- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005800- On windows, ``os.chdir()`` given unicode was not working if
5801 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5802 this code path is really executed because I cannot move to such directory on
5803 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005804
Georg Brandlba83f822010-03-14 09:50:54 +00005805- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5806 element is temporarily replaced with an equivalent frozenset. But the
5807 eventual KeyError would always report the empty ``frozenset()`` as the missing
5808 key. Now it correctly refers to the initial element.

5827
Walter Dörwalded960ac2009-05-03 22:36:33 +00005828- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5829 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5830 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5831 of using the replace error handler in PyUnicode_DecodeUTF8().
5832
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005833- Issue #3739: The unicode-internal encoder now reports the number of characters
5834 consumed like any other encoder (instead of the number of bytes).
5835
Georg Brandlba83f822010-03-14 09:50:54 +00005836- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5837 allocator will be automatically disabled when running under Valgrind. This
5838 gives improved memory leak detection when running under Valgrind, while taking
5839 advantage of pymalloc at other times.

7009 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7010 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007207- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7208
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007209- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7210 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7211 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7212 ``printf`` function, whereas PyString_FromFormat has an independent
7213 implementation and uses "%zd" on all platforms for size_t values.
7214 This makes a difference on win64, where ``printf`` needs "%Id" to display
7215 64bit values.
7216
Benjamin Peterson97179b02008-09-09 20:55:01 +00007217- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7221 object; previously an int would be returned for small values. the __long__
7222 method is allowed to return either an int or a long, but the behaviour of
7223 float objects should not change to respect backward compatibility.
7224
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007225- Issue #3751: str.rpartition would perform a left-partition when called with
7226 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007231 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007232 was correctly parsed but parsing of subsequent arguments failed.
7233
Vinay Sajip35e3b032008-09-01 14:33:59 +00007234- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007235 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7236 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7237 when given a tuple of classes as second argument, were looking up
7238 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7239 type object.
7240
Neal Norwitz18aa3882008-08-24 05:04:52 +00007241- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007310 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7311 for catch_warnings() also led to an improvement in the raising of a

7384-----------------
7385
Guido van Rossumf8402962008-08-20 15:01:50 +00007386- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7387 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7388 extensions do not automatically benefit from the class attribute
7389 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7390 to their tp_flags field if they care. This is a backwards
7391 compatibility feature; in 3.0, all types will use the cache by
7392 default.
7393
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007394- Keyword arguments can now follow starred arguments. (``f(a, *args,
7395 keyword=23)`` is now valid syntax.)
7396
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007397- ctypes function pointers that are COM methods have a boolean True
7398 value again.

7409
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007410- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7411 (64bit Unix, for example), unichr() would truncate its argument and return
7412 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7413
Neal Norwitze7d8be82008-07-31 17:17:14 +00007414- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007416- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7417 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7418
Antoine Pitrou92f82162008-07-25 22:22:08 +00007419- Issue #1819: function calls with several named parameters are now on
7420 average 35% faster (as measured by pybench).
7421
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007422- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7423 the python debugger steps into a class statement: the free variables (local
7424 variables defined in an outer scope) would be deleted from the outer scope.
7425
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007426- Issue #2620: Overflow checking when allocating or reallocating memory
7427 was not always being done properly in some python types and extension
7428 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7429 all been updated to perform better checks and places in the code that
7430 would previously leak memory on the error path when such an allocation
7431 failed have been fixed.

7437
Benjamin Petersone977ad42008-08-20 01:42:01 +00007438- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7439 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7440
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007441- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7442 version reported by these tools does not necessarily follow the python
7443 version numbering scheme, so the module is less strict when parsing it.
7444
Nick Coghlanf70385a2008-08-18 12:42:46 +00007445- Issue #2235: Added Py3k warnings for types which will become unhashable
7446 under the stricter __hash__ inheritance rules in 3.0. Several types
7447 which did not meet the rules for hash invariants and were already
7448 unhashable in 3.0 have now been explicitly flagged as unhashable in
7449 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7450 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7451
Brett Cannon88f801d2008-08-18 00:46:22 +00007452- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7453 imported into the module but exposed as part of the module's API.
7454

7474 after a 302 response in the case of not going through a proxy.
7475
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007476- Issue #2676: in the email package, content-type parsing was hanging on
7477 pathological input because of quadratic or exponential behaviour of a
7478 regular expression.
7479
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007480- Issue #3476: binary buffered reading through the new "io" library is now
7481 thread-safe.
7482
Brett Cannonbf3157b2008-08-14 05:00:03 +00007483- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7484 since mimetools itself is deprecated. Because modules are cached, all
7485 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7486
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007487- Issue #3134: shutil referenced undefined WindowsError symbol.

7490 menu entries were not deleted.
7491
Brett Cannon83e81842008-08-09 23:30:55 +00007492- Copied the implementation of reduce() to _functools.reduce() to have a

7494
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007495- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7496 a MemoryError rather than silently stop the iteration.
7497
Guido van Rossum59ce9012008-08-09 14:55:34 +00007498- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7499 to _sre.compile() will now be rejected. This should not affect anybody
7500 since the re.compile() function never generates invalid re-bytecode.
7501
Skip Montanaroa032bf42008-08-08 22:52:51 +00007502- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7503 upon first access it can be automatically initialized from the csv file if
7504 it wasn't initialized during instantiation.
7505
Brett Cannon3aa2a492008-08-06 22:28:09 +00007506- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7507 the reload() built-in has been removed.
7508
Brett Cannon7e30b672008-08-04 21:52:25 +00007509- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007510 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7518 raised an AttributeError.
7519
Benjamin Peterson01a24322008-07-28 23:35:27 +00007520- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007521 asking for a specific length. This problem only affected files opened
7522 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007523

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007547- Issue #3394: zipfile.writestr sets external attributes when passed a
7548 file name rather than a ZipInfo instance, so files are extracted with
7549 mode 0600 rather than 000 under Unix.
7550
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007551- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7552 argument in python 2.5, this broke code that subclassed Popen to include its
7553 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007563- Issue #2235: the C API function PyObject_HashNotImplemented and its
7564 interaction with the tp_hash slot (added in 2.6b2) are now documented
7565
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007566- Issue #643841: The language reference now provides more detailed
7567 coverage of the lookup process for special methods. The disclaimers
7568 regarding lack of coverage of new-style classes have also been
7569 removed, since the coverage is now fairly reasonable.

7573================================
7574
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007575*Release date: 17-Jul-2008*
7576
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007577Core and Builtins
7578-----------------
7579
Georg Brandl3e483f62008-07-16 22:57:41 +00007580- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7581 its methods now allow for items objects that can be converted to
7582 an integer using operator.index().
7583
Mark Dickinson64b7e502008-07-16 09:40:03 +00007584- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7585 produced a ValueError instead of giving the correct float.
7586
Eric Smitha5fa5a22008-07-16 00:11:49 +00007587- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7588 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7589
Mark Dickinson7103aa42008-07-15 19:08:33 +00007590- Issue #3008: the float type has a new instance method 'float.hex'
7591 and a new class method 'float.fromhex' to convert floating-point
7592 numbers to and from hexadecimal strings, respectively.
7593
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007594- Issue #2235: __hash__ is once again inherited by default. To allow
7595 collections.Hashable to remain meaningful in the presence of the
7596 default hash implementation (object.__hash__), it is now possible
7597 to explicit block inheritance of hash by setting __hash__=None at
7598 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7599 level.
7600
Nick Coghlanb028f502008-07-13 14:52:36 +00007601- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7602 the parent module cannot be found while performing an absolute import.
7603 This means that an incorrectly defined __package__ attribute will
7604 now only prevent relative imports in that module rather than causing
7605 all imports from that module to fail.
7606
Nick Coghlan14ff9942008-07-08 14:21:42 +00007607- Issue #2517: Allow unicode messages in Exceptions again by correctly
7608 bypassing the instance dictionary when looking up __unicode__ on
7609 new-style classes.
7610
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007611- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7612 set to a custom object whose write() method happens to install
7613 another file in sys.stdout.
7614
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007615- Issue #3088: Corrected a race condition in classes derived from
7616 threading.local: the first member set by a thread could be saved in
7617 another thread's dictionary.
7618
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007619- Issue #3004: Minor change to slice.indices(): the start and stop
7620 arguments are now treated identically, making the behaviour easier
7621 to describe and understand. For example, slice(None, -10,
7622 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7623 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7624 10, -1).
7625
Georg Brandl278fc502008-07-19 12:46:12 +00007626- Issue #3219: Calling a function with repeated keyword arguments,
7627 f(a=2, a=23), would not cause a syntax error. This was a regression
7628 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007629
Georg Brandl278fc502008-07-19 12:46:12 +00007630- Issue #2862: Make int and float freelist management consistent with
7631 other freelists. Changes their CompactFreeList apis into
7632 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007633

7635-------
7636
Thomas Heller57adf222008-08-14 19:10:48 +00007637- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7638 api functions without holding the GIL, which could lead to a fatal
7639 error when they failed.
7640
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007641- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007649- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7650 ForkingPickler.register() to resolve conflict with ctypes.
7651
Vinay Sajip51e65192008-07-18 09:01:10 +00007652- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007653
Thomas Heller880f5292008-07-15 19:39:38 +00007654- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7655 a valid dlerror() message.
7656
Thomas Heller2bad6572008-07-15 17:19:50 +00007657- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7658 incomplete structure was created.
7659
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007660- Issue #3339: dummy_thread.acquire() should not return None.

7663
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007664- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007665
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007666- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7667 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007668 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007669 content-length. The problem had been corrected in the 2.4 branch, but never
7670 merged into trunk.
7671
Georg Brandle78fbcc2008-07-05 10:13:36 +00007672- Issue #2663: add filtering capability to shutil.copytree().

7678- Issue #1746: Correct handling of zipfile archive comments (previously
7679 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007680 Zip files with archives by setting the 'comment' attribute of a ZipFile.

Vinay Sajip51e65192008-07-18 09:01:10 +00007682- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007683 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007684
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007685- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7686 handling is now the same as that of other special attributes like __name__).
7687
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007688- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7689 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008076 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008077
8078 This is controlled by the configure argument ``--with-universal-archs``:
8079
8080 - ``--with-universal-archs=all``: install 4-way universal
8081
8082 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8083
8084 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8085
8086 This option should be used in combination with ``--enable-universalsdk=``.
8087
8088 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 +00008137- Issue #1631171: Re-implement the 'warnings' module in C (the
8138 original Python code has been kept as backup). This will allow for
8139 using the 'warning's machinery in such places as the parser where
8140 use of pure Python code is not possible. Both the ``showarning()``
8141 and ``formatwarning()`` gain an optional 'line' argument which is
8142 not called by default for backwards-compatibility reasons. Setting
8143 ``warnings.showwarning()`` to an implementation that lacks support
8144 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Issue #2550: The approach used by client/server code for obtaining
8208 ports to listen on in network-oriented tests has been refined in an
8209 effort to facilitate running multiple instances of the entire
8210 regression test suite in parallel without issue.
8211 test_support.bind_port() has been fixed such that it will always
8212 return a unique port -- which wasn't always the case with the
8213 previous implementation, especially if socket options had been set
8214 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8215 new implementation of bind_port() will actually raise an exception
8216 if it is passed an AF_INET/SOCK_STREAM socket with either the
8217 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8218 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8219 the socket it's been passed. This currently only applies to
8220 Windows. This option prevents any other sockets from binding to the
8221 host/port we've bound to, thus removing the possibility of the
8222 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8223 when a second SOCK_STREAM socket binds and accepts to a host/port
8224 that's already been bound by another socket. The optional preferred
8225 port parameter to bind_port() has been removed. Under no
8226 circumstances should tests be hard coding ports!
8227
8228 test_support.find_unused_port() has also been introduced, which will
8229 pass a temporary socket object to bind_port() in order to obtain an
8230 unused port. The temporary socket object is then closed and
8231 deleted, and the port is returned. This method should only be used
8232 for obtaining an unused port in order to pass to an external program
8233 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8234 a parameter to a server-oriented class that doesn't give you direct
8235 access to the underlying socket used.
8236
8237 Finally, test_support.HOST has been introduced, which should be used
8238 for the host argument of any relevant socket calls (i.e. bind and
8239 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008240
8241 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

8245
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246 It is now possible for multiple instances of the regression test

8513Core and builtins
8514-----------------
8515
Fred Drakea8ee94b2008-03-01 02:45:07 +00008516- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008517 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008518
Georg Brandlad61bc82008-02-23 15:11:18 +00008519- Issue #2067: file.__exit__() now calls subclasses' close() method.
8520
8521- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008522
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008523- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008524 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008525
Eric Smitha73fbe72008-02-23 03:09:44 +00008526- Added the future_builtins module, which contains hex() and oct().
8527 These are the PEP 3127 version of these functions, designed to be
8528 compatible with the hex() and oct() builtins from Python 3.0. They
8529 differ slightly in their output formats from the existing, unchanged
8530 Python 2.6 builtins. The expected usage of the future_builtins
8531 module is:
8532 from future_builtins import hex, oct
8533
Eric Smith7ef40bf2008-02-20 23:34:22 +00008534- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8535 exponents for exponents with absolute value < 100. Follows C99
8536 standard. This is a change on Windows, which would use 3 digits.
8537 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8538 so that any alterations it does to the resulting string will be
8539 available in stringlib/formatter.h (for float.__format__).
8540
Eric Smith5a3c1352008-02-19 13:21:56 +00008541- Implemented PEP 3101, Advanced String Formatting. This adds a new
8542 builtin format(); a format() method for str and unicode; a
8543 __format__() method to object, str, unicode, int, long, float, and
8544 datetime; the class string.Formatter; and the C API
8545 PyObject_Format().
8546
Georg Brandl3ee81df2008-05-17 18:14:43 +00008547- Fixed several potential crashes, all caused by specially crafted
8548 __del__ methods exploiting objects in temporarily inconsistent
8549 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008550
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008551- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008552 prevent a possible crash: an Abstract Base Class would try to access
8553 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008554
Georg Brandl3ee81df2008-05-17 18:14:43 +00008555- Fixed repr() and str() of complex numbers with infinity or nan as
8556 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008557
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558- Clear all free lists during a gc.collect() of the highest generation
8559 in order to allow pymalloc to free more arenas. Python may give back
8560 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Issue #2045: Fix an infinite recursion triggered when printing a
8563 subclass of collections.defaultdict, if its default_factory is set
8564 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008565
Christian Heimesf75dbef2008-02-08 00:11:31 +00008566- Fixed a minor memory leak in dictobject.c. The content of the free
8567 list was not freed on interpreter shutdown.
8568
Georg Brandl21e99f42010-03-07 15:23:59 +00008569- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008570 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008571
Georg Brandl3ee81df2008-05-17 18:14:43 +00008572- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8573 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008574 to compact the internal free lists of pre-allocted ints and floats.
8575
Georg Brandl3ee81df2008-05-17 18:14:43 +00008576- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8577 calls. Python expected the return type int but the fork familie
8578 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008579
Georg Brandl3ee81df2008-05-17 18:14:43 +00008580- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8581 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008582
Georg Brandl3ee81df2008-05-17 18:14:43 +00008583- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8584 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008585
Georg Brandl3ee81df2008-05-17 18:14:43 +00008586- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8587 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8590 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- Patch #1473257: generator objects gain a gi_code attribute. This is
8593 the same object as the func_code attribute of the function that
8594 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008595
Georg Brandl3ee81df2008-05-17 18:14:43 +00008596- Issue #1920: "while 0" statements were completely removed by the
8597 compiler, even in the presence of an "else" clause, which is
8598 supposed to be run when the condition is false. Now the compiler
8599 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008600
Guido van Rossumeead05f2008-01-24 18:21:02 +00008601- A few crashers fixed: weakref_in_del.py (issue #1377858);
8602 loosing_dict_ref.py (issue #1303614, test67.py);
8603 borrowed_ref_[34].py (not in tracker).
8604
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008605- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008606 suppressed while an extension is loaded by calling SetErrorMode in
8607 dynload_win.c. The error is still reported properly.
8608
Georg Brandl3ee81df2008-05-17 18:14:43 +00008609- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008610 several extension methods and modules do not work without unicode
8611 support.
8612
Georg Brandl26543b12008-01-21 18:36:51 +00008613- Issue #1882: when compiling code from a string, encoding cookies in the
8614 second line of code were not always recognized correctly.
8615
Georg Brandl14404b62008-01-19 19:27:05 +00008616- Issue #1679: "0x" was taken as a valid integer literal.
8617
Georg Brandl6caad7d2008-01-26 14:19:22 +00008618- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008619 added.
8620
Christian Heimesc94e2b52008-01-14 04:13:37 +00008621- sys.float_info / PyFloat_GetInfo: The floating point information
8622 object was converted from a dict to a specialized structseq object.
8623
Georg Brandl3ee81df2008-05-17 18:14:43 +00008624- Patch #1816: Added sys.flags structseq. It exposes the status of
8625 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008626
Georg Brandl3ee81df2008-05-17 18:14:43 +00008627- Objects/structseq.c: Implemented new structseq representation. The
8628 patch makes structseqs (e.g. the return value of os.stat) more
8629 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008630
Georg Brandl3ee81df2008-05-17 18:14:43 +00008631- Patch #1700288: added a type attribute cache that caches method
8632 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008633
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008634- Bug #1776: __import__() no longer accepts filenames on any platform.
8635 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008636
Georg Brandlaed6c662008-01-07 17:25:53 +00008637- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8638
Georg Brandl3ee81df2008-05-17 18:14:43 +00008639- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8640 envvar and sys.dont_write_bytecode attribute. All these can be set
8641 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008642
Georg Brandl3ee81df2008-05-17 18:14:43 +00008643- Improve some exception messages when Windows fails to load an
8644 extension module. Now we get for example '%1 is not a valid Win32
8645 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008646
Georg Brandl3ee81df2008-05-17 18:14:43 +00008647- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008649- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8650 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008651
Christian Heimes0a8143f2007-12-18 23:22:54 +00008652- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008653 and INF. float("nan"), float("inf") and float("-inf") now work on
8654 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008655
Georg Brandl3ee81df2008-05-17 18:14:43 +00008656- Compiler now generates simpler and faster code for dictionary
8657 literals. The oparg for BUILD_MAP now indicates an estimated
8658 dictionary size. There is a new opcode, STORE_MAP, for adding
8659 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008660
Georg Brandl3ee81df2008-05-17 18:14:43 +00008661- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00008662
Georg Brandl3ee81df2008-05-17 18:14:43 +00008663- Issue #1620: New property decorator syntax was modifying the
8664 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00008665
Georg Brandl3ee81df2008-05-17 18:14:43 +00008666- Issue #1538: Avoid copying string in split/rsplit if the split char
8667 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008668
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008669- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008670 SystemError.
8671
Nick Coghlanef01d822007-12-03 12:55:17 +00008672- PEP 366: Allow explicit relative imports when executing modules
8673 inside packages with the -m switch via a new module level
8674 __package__ attribute.
8675
Georg Brandl3ee81df2008-05-17 18:14:43 +00008676- Issue #1402: Fix a crash on exit, when another thread is still
8677 running, and if the deallocation of its frames somehow calls the
8678 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008679

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008683 attribute of an empty cell object.
8684
Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Issue #1460: The utf-7 incremental decoder did not accept truncated
8686 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008687
Georg Brandl3ee81df2008-05-17 18:14:43 +00008688- Patch #1739468: Directories and zipfiles containing a __main__.py
8689 file can now be directly executed by passing their name to the
8690 interpreter. The directory/zipfile is automatically inserted as the
8691 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008692
Georg Brandl3ee81df2008-05-17 18:14:43 +00008693- Issue #1265: Fix a problem with sys.settrace, if the tracing
8694 function uses a generator expression when at the same time the
8695 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008696
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008697- sets and frozensets now have an isdisjoint() method.
8698
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008699- optimize the performance of builtin.sum().
8700
Neal Norwitz44f326e2007-10-05 05:29:17 +00008701- Fix warnings found by the new version of the Coverity checker.
8702
Georg Brandl21e99f42010-03-07 15:23:59 +00008703- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008704 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8705 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008706
Georg Brandl3ee81df2008-05-17 18:14:43 +00008707- Issue #1686386: Tuple's tp_repr did not take into account the
8708 possibility of having a self-referential tuple, which is possible
8709 from C code. Nor did object's tp_str consider that a type's tp_str
8710 could do something that could lead to an inifinite recursion.
8711 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8712 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008713
Georg Brandl3ee81df2008-05-17 18:14:43 +00008714- Issue #1164: It was possible to trigger deadlock when using the
8715 'print' statement to write to a file since the GIL was not released
8716 as needed. Now PyObject_Print() does the right thing along with
8717 various tp_print implementations of the built-in types and those in
8718 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008719
Georg Brandl3ee81df2008-05-17 18:14:43 +00008720- Issue #1147: Exceptions were directly allowing string exceptions in
8721 their throw() method even though string exceptions no longer
8722 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008723
Georg Brandl3ee81df2008-05-17 18:14:43 +00008724- Issue #1096: Prevent a segfault from getting the repr of a very
8725 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008726
Brett Cannon1e534b52007-09-07 04:18:30 +00008727- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008728 PyObject_Call() never calling back out to Python code to trigger
8729 recursion depth updates/checks. Required the creation of a static
8730 RuntimeError instance in case normalizing an exception put the
8731 recursion check value past its limit. Fixes crashers
8732 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008733
Georg Brandl3ee81df2008-05-17 18:14:43 +00008734- Patch #1031213: Decode source line in SyntaxErrors back to its

8738 with %G.
8739
Georg Brandl3ee81df2008-05-17 18:14:43 +00008740- Prevent expandtabs() on string and unicode objects from causing a
8741 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008742
Georg Brandl3ee81df2008-05-17 18:14:43 +00008743- Issue #1733488: Fix compilation of bufferobject.c on AIX.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008747- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008748 __*__ attributes. (Some already existed, e.g., __doc__ and

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008751- Add -3 option to the interpreter to warn about features that are
8752 deprecated and will be changed/removed in Python 3.0.
8753
Georg Brandl2134e752007-05-21 20:34:16 +00008754- Patch #1686487: you can now pass any mapping after '**' in function
8755 calls.
8756
Collin Winter62903052007-05-18 23:11:24 +00008757- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008758 "except E as target:". This is to provide forwards compatibility
8759 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008760
Brett Cannon229cee22007-05-05 01:34:02 +00008761- Deprecate BaseException.message as per PEP 352.
8762
Georg Brandl3ee81df2008-05-17 18:14:43 +00008763- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008764 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008765
Vinay Sajip8549ce32007-05-06 17:53:37 +00008766- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008767 setting a plain string, ie don't expand to single letter identifiers.
8768
Raymond Hettinger13936692007-04-11 18:40:58 +00008769- Request #1191699: Slices can now be pickled.
8770
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008771- Request #1193128: str.translate() now allows a None argument for
8772 translations that only remove characters without re-mapping the
8773 remaining characters.
8774
Georg Brandl5cb76c12007-03-21 09:00:39 +00008775- Patch #1682205: a TypeError while unpacking an iterable is no longer
8776 masked by a generic one with the message "unpack non-sequence".
8777
Neal Norwitzaa754b72007-03-21 06:39:48 +00008778- Remove unused file Python/fmod.c.
8779
Guido van Rossum143b5642007-03-23 04:58:42 +00008780- Bug #1683368: The object.__init__() and object.__new__() methods are
8781 now stricter in rejecting excess arguments. The only time when
8782 either allows excess arguments is when it is not overridden and the
8783 other one is. For backwards compatibility, when both are
8784 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008785 warning later). Also, type.__init__() insists on the same signature
8786 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008787
Georg Brandl3ee81df2008-05-17 18:14:43 +00008788- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8789 object to complex using its __complex__() method before falling back
8790 to the __float__() method. Therefore, the functions in the cmath
8791 module now can operate on objects that define a __complex__()
8792 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008793
Georg Brandl3ee81df2008-05-17 18:14:43 +00008794- Patch #1623563: allow __class__ assignment for classes with
8795 __slots__. The old and the new class are still required to have the
8796 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008797

8802 ``object.__reduce_ex__()`` is called with an object that is faking
8803 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008804
Georg Brandl3ee81df2008-05-17 18:14:43 +00008805- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008808- Patch #1444529: the builtin compile() now accepts keyword arguments.
8809
Georg Brandl7b9c5552007-03-12 14:30:05 +00008810- Bug #1678647: write a newline after printing an exception in any
8811 case, even when converting the value to a string failed.
8812
Georg Brandl871f1bc2007-03-12 13:17:36 +00008813- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008814 its argument, if it exists. If not, it will work like before. This
8815 allows customizing the output of dir() in the presence of a
8816 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008817
Collin Winter276887b2007-03-12 16:11:39 +00008818- Patch #922167: Python no longer segfaults when faced with infinitely
8819 self-recursive reload() calls (as reported by bug #742342).
8820
Georg Brandl3ee81df2008-05-17 18:14:43 +00008821- Patch #1675981: remove unreachable code from ``type.__new__()``
8822 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008824- Patch #1491866: change the complex() constructor to allow
8825 parthensized forms. This means complex(repr(x)) now works instead of
8826 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008827
Georg Brandlaa2321b2007-03-07 00:40:28 +00008828- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008829 makes the filenames the warning module prints much more sensible
8830 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008831
Georg Brandl49aafc92007-03-07 00:34:46 +00008832- Variant of patch #697613: don't exit the interpreter on a SystemExit
8833 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008834 variable is given, but break into the interactive interpreter just
8835 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008840- Bug #1674503: close the file opened by execfile() in an error
8841 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008842
Georg Brandl0fca97a2007-03-05 22:28:08 +00008843- Patch #1674228: when assigning a slice (old-style), check for the
8844 sq_ass_slice instead of the sq_slice slot.
8845
Georg Brandl3ee81df2008-05-17 18:14:43 +00008846- When printing an unraisable error, don't print exceptions. before
8847 the name. This duplicates the behavior whening normally printing
8848 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008849
Georg Brandl3ee81df2008-05-17 18:14:43 +00008850- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008856- Bug #1377858: Fix the segfaulting of the interpreter when an object
8857 created a weakref on itself during a __del__ call for new-style
8858 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008859
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008860- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

8896 returns) and inline unconditional jumps to returns.
Neal Norwitzcbeb6872006-10-14 21:33:38 +00008897
Georg Brandl2c1375c2006-10-12 11:27:59 +00008898- Bug #1545497: when given an explicit base, int() did ignore NULs
8899 embedded in the string to convert.
8900
Georg Brandl846f73a2006-10-08 07:11:54 +00008901- Bug #1569998: break inside a try statement (outside a loop) is now
8902 recognized and rejected.
8903

8907 were fixed to not rely on undefined behaviour of the C compiler
8908 anymore.

8911 number of arguments, as was the case in Python 2.4.
8912
Georg Brandl5d59c092006-09-30 08:43:30 +00008913- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00008914 keyword arguments any more (previously they accepted them, but
8915 didn't use them).

Georg Brandl4e933132006-09-06 20:05:58 +00008931- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8932 Also make sure that every exception class has __module__ set to
8933 'exceptions'.

Neal Norwitzdac090d2006-09-05 03:53:08 +00008948- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008949 generator expressions (x for x, in ... ) works again. Fixing this
8950 problem required changing the .pyc magic number. This means that
8951 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009751- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9752 with RFC 3207 and forgets any knowledge obtained from the server not
9753 obtained from the TLS negotiation itself. Patch contributed by Bill
9754 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009755
Georg Brandl3ee81df2008-05-17 18:14:43 +00009756- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009757 that the SMTP.starttls() caller no longer needs to call ehlo()
9758 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009759 does not claim to support starttls. Adds the
9760 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9841 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9842 silently miscode subclasses of those types. Now, it raises a
9843 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009844

Georg Brandl3ee81df2008-05-17 18:14:43 +00009859 time so that opening a database previously created with the DB_DUP
9860 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9861 opens. Specifically: dictionary assignment to a DB object will
9862 replace all values for a given key when the database allows
9863 duplicate values. DB users should use DB.put(k, v) when they want
9864 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009865

9871 characters with ASCII value less than 32. Also, it correctly quotes
9872 dots only if they occur on a single line, as opposed to the previous
9873 behavior of quoting dots if they are the second character of any
9874 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009875

10216 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10217 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010218
10219- Patch #1720595: add T_BOOL to the range of structmember types.
10220
10221- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10222 ``PyFloat_GetInfo()`` to the float API.
10223
Georg Brandl3ee81df2008-05-17 18:14:43 +000010224- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10225 of w# format code incorrectly truncated the length to an int, even
10226 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10227 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010228
Georg Brandl3ee81df2008-05-17 18:14:43 +000010229- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10230 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010231
Georg Brandl3ee81df2008-05-17 18:14:43 +000010232- PEP 3123: Provide forward compatibility with Python 3.0, while
10233 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10234 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010235
Georg Brandl3ee81df2008-05-17 18:14:43 +000010236- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10237 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010238
10239- Patch #1733960: Allow T_LONGLONG to accept ints.
10240
10241- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10242
Christian Heimes000a0742008-01-03 22:16:32 +000010243- Added a new API function ``PyImport_ImportModuleNoBlock``.
10244
Georg Brandl6caad7d2008-01-26 14:19:22 +000010245- Bug #1637022: Prefix AST symbols with _Py_.
10246
10247- Fix some leftovers from the conversion from int to Py_ssize_t
10248 (relevant to strings and sequences of more than 2**31 items).
10249
10250- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10251 outside of pystate.c and should not be necessary.
10252
Georg Brandl3ee81df2008-05-17 18:14:43 +000010253- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10254 absolute imports. In earlier versions they might have used relative
10255 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010256
Georg Brandl3ee81df2008-05-17 18:14:43 +000010257- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10258 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010259
Georg Brandl3ee81df2008-05-17 18:14:43 +000010260- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10261 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010266- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10267 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10268 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10269 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010270
Georg Brandl3ee81df2008-05-17 18:14:43 +000010271- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10272 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +000010281- buildtools now raises a DeprecationWarning.
10282
Georg Brandl3ee81df2008-05-17 18:14:43 +000010283- Removed the macfs module. It had been deprecated since Python 2.5.
10284 This lead to the deprecation of macostools.touched() as it relied
10285 solely on macfs and was a no-op under OS X.
