677
678- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
679 and later systems as is currently done for Python 3.x installers.
680 For 2.7.7 only, we will provide three installers:
681 the legacy deprecated 10.3+ 32-bit-only format;
682 the newer 10.5+ 32-bit-only format;
683 and the unchanged 10.6+ 64-/32-bit format.
684 Although binary installers will no longer be available from
685 python.org as of 2.7.8, it will still be possible to build from
686 source on 10.3.9 and 10.4 systems if necessary.
687 See Mac/BuildScript/README.txt for more information.

2066
Ned Deily18fae3f2013-01-31 01:24:55 -08002067- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2068 In particular, fix extension module build failures when trying to use
2069 32-bit-only installer Pythons on systems with Xcode 4 (currently
2070 OS X 10.8, 10.7, and optionally 10.6).
2071 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2072 * Since Xcode 4 removes ppc support, extension module builds now
2073 check for ppc compiler support and by default remove ppc and
2074 ppc64 archs when they are not available.
2075 * Extension module builds now revert to using system installed
2076 headers and libs (/usr and /System/Library) if the SDK used
2077 to build the interpreter is not installed or has moved.
2078 * Try to avoid building extension modules with deprecated
2079 and problematic Apple llvm-gcc compiler. If original compiler
2080 is not available, use clang instead by default.

2448 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002524- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2525 Distutils-based packages with C extension modules may fail because
2526 Apple has removed gcc-4.2, the version used to build python.org
2527 64-bit/32-bit Pythons. If the user does not explicitly override
2528 the default C compiler by setting the CC environment variable,
2529 Distutils will now attempt to compile extension modules with clang
2530 if gcc-4.2 is required but not found. Also as a convenience, if
2531 the user does explicitly set CC, substitute its value as the default
2532 compiler in the Distutils LDSHARED configuration variable for OS X.
2533 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2534 SDK, neither of which are available in Xcode 4. This change does not
2535 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002785- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2786 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2787 interpreter process. This could cause failures in non-Distutils subprocesses
2788 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002789 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002790 deployment target only in the environment of each build subprocess. It is
2791 still possible to globally override the default by setting
2792 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2793 greater or equal to the default value, the value with which the interpreter
2794 was built.

2823 updating the check interval, so if the user decreases the check interval,
2824 the ticker doesn't have to wind down to zero from the old starting point
2825 before the new interval takes effect. And if the user increases the
2826 interval, it makes sure the new limit takes effect right away rather have an
2827 early task switch before recognizing the new interval.

Antoine Pitrou66b5df62010-09-27 18:16:46 +00003794- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
3795 received. Now sendall() properly calls signal handlers if necessary,
3796 and retries sending if these returned successfully, including on sockets
3797 with a timeout.

3814 by Andrew Bennetts.

3823
Raymond Hettinger20397532010-09-12 02:11:45 +00003824- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3825 This prevents user-created self-referencing ordered dictionaries from
3826 becoming permanently uncollectable GC garbage. The downside is that
3827 removing __del__ means that the internal doubly-linked list has to wait for
3828 GC collection rather than freeing memory immediately when the refcnt drops
3829 to zero.
3830

3837 to fetch the original errno, or to filter timeout errors. Now the
3838 original error is re-raised.

R. David Murray7c4bf552010-08-25 01:45:57 +00003860- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3861 character years even if the message contains RFC822 two character years.
3862

3876
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003877- Issue #9617: Signals received during a low-level write operation aren't
3878 ignored by the buffered IO layer anymore.
3879
Benjamin Peterson52c36052010-08-21 03:03:22 +00003880- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3882
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003883- Issue #9626: the view methods for collections.OrderedDict() were returning

3892 and a BadZipfile error is raised if it doesn't match (as used to be the
3893 case in Python 2.5 and earlier).
3894
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003895- Issue #9550: a BufferedReader could issue an additional read when the
3896 original read request had been satisfied, which could block indefinitely
3897 when the underlying raw IO channel was e.g. a socket. Report and original
3898 patch by Jason V. Miller.

4290 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4291 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

4303 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004648 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4649 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4650 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4670Core and Builtins
4671-----------------
4672
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004673- Issue #7301: Add environment variable $PYTHONWARNINGS.
4674
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004675- Issue #8329: Don't return the same lists from select.select when no fds are
4676 changed.
4677
Georg Brandlfee0f442010-05-22 21:26:21 +00004678- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004679 on 64-bit machines. The shift count for either left or right shift is
4680 permitted to be up to sys.maxsize.
4681
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004682- Ensure that tokenization of identifiers is not affected by locale.
4683
Georg Brandlfee0f442010-05-22 21:26:21 +00004684- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004685
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004686- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4687
Georg Brandlfee0f442010-05-22 21:26:21 +00004688- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4689 with a non-empty format string. This is an effort to future-proof user
4690 code. If a derived class does not currently implement __format__ but later
4691 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004692 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004693 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004694
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004695- Issue #8268: Old-style classes (not just instances) now support weak

4707
Victor Stinner66644262010-03-10 22:30:19 +00004708- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004709 (SIGINT). If an error occurs while importing the site module, the error is
4710 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004711 module.

4725
Georg Brandlfee0f442010-05-22 21:26:21 +00004726- Issue #8257: The Decimal construct now accepts a float instance directly,
4727 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004728
4729 >>> Decimal(1.1)
4730 Decimal('1.100000000000000088817841970012523233890533447265625')
4731
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004732- collections.Counter() now supports a subtract() method.
4733
Georg Brandlfee0f442010-05-22 21:26:21 +00004734- The functools module now has a total_ordering() class decorator to simplify
4735 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004736
Georg Brandlfee0f442010-05-22 21:26:21 +00004737- The functools module also adds cmp_to_key() as a tool to transition old-style
4738 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004739
Georg Brandlfee0f442010-05-22 21:26:21 +00004740- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4741 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004742
Georg Brandlfee0f442010-05-22 21:26:21 +00004743- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4744 InvalidOperation instead of returning False. (Comparisons involving a quiet
4745 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4746 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004747
Georg Brandlfee0f442010-05-22 21:26:21 +00004748- Issue #2531: Comparison operations between floats and Decimal instances now
4749 return a result based on the numeric values of the operands; previously they
4750 returned an arbitrary result based on the relative ordering of id(float) and
4751 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004752
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004753- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004754 argument `-` which tells it to read files to compile from stdin. Each line is
4755 read on demand and the named file is compiled immediately. (Original patch by
4756 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004757
Georg Brandlfee0f442010-05-22 21:26:21 +00004758- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004761- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4762 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004763 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004764
Georg Brandlfee0f442010-05-22 21:26:21 +00004765- Comparisons using one of <, <=, >, >= between a complex instance and a
4766 Fractions instance now raise TypeError instead of returning True/False. This
4767 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4768 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004769
Michael Foorde6410c52010-03-29 20:04:23 +00004770- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004779- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004780 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4781 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004782
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004783- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00004824 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4825 log file to compute the next rollover time. If the log file does not exist,
4826 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004827

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004867- Issue #8300: When passing a non-integer argument to struct.pack with any
4868 integer format code, struct.pack first attempts to convert the non-integer
4869 using its __index__ method. If that method is non-existent or raises
4870 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004872- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4873 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4874 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004875 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4876 inconsistent: __int__ was used for some integer codes but not for others, and
4877 the set of integer codes for which it was used differed between native packing
4878 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005090- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
5091 now also used by regrtest to run all the tests in a temporary directory. The
5092 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent

5110 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00005111 library would return a bogus result; on Solaris, it was possible to crash the
5112 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00005125- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5126 and add the additional members returned in an OSVERSIONINFOEX structure. The
5127 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00005130- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5131 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5132 returning NULL. The macro now returns a statically allocated empty string
5133 instead.

5143 strings,
5144 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5145 numeric strings corresponding to subnormal values,
5146 (3) a memory leak for some values large enough to cause overflow, and
5147 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00005178- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00005179 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00005180 Also, raise ValueError rather than TypeError when an unknown TIPC address
5181 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005185- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005186 file position when calling `truncate()`. It would previously change the file
5187 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005188 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5189
Georg Brandlba83f822010-03-14 09:50:54 +00005190- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5191 class used to represent files stored inside an archive. The new
5192 implementation is significantly faster and can be wrapped in a
5193 ``io.BufferedReader`` object for more speedups. It also solves an issue
5194 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5195 Patch by Nir Aides.

Benjamin Peterson2deb5c72010-01-27 02:16:42 +00005197- Issue #7792: Registering non-classes to ABCs raised an obscure error.

5203 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00005204
Georg Brandlba83f822010-03-14 09:50:54 +00005205- Issue #7748: Since unicode values are supported for some metadata options in
5206 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5207 encoded string for them. This ensures that the upload and register commands
5208 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005285- The ``__complex__()`` method is now looked up on the class of instances to
5286 make it consistent with other special methods.

5293 These functions and methods now raise TypeError instead. The majority of the
5294 effects of this change are in the extension modules, but some core functions
5295 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5296 and many unicode/str methods.

5312 internal representation of a long.

5461 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5462 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005463
Georg Brandlba83f822010-03-14 09:50:54 +00005464- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5465 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005466
Georg Brandlba83f822010-03-14 09:50:54 +00005467- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

5469 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005477
Georg Brandlba83f822010-03-14 09:50:54 +00005478- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5479 decimal string that's guaranteed to round back to x under correct rounding
5480 (with round-half-to-even rounding mode). Previously it gave a string based on
5481 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5482 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5483 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005484
Georg Brandlba83f822010-03-14 09:50:54 +00005485- Issue #7117: On almost all platforms: float-to-string and string-to-float
5486 conversions within Python are now correctly rounded. Places these conversions
5487 occur include: str for floats and complex numbers; the float and complex
5488 constructors; old-style and new-style numeric formatting; serialization and
5489 deserialization of floats and complex numbers using marshal, pickle and json;
5490 parsing of float and imaginary literals in Python code; Decimal-to-float
5491 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005492
Georg Brandlba83f822010-03-14 09:50:54 +00005493 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5494 providing correctly-rounded strtod and dtoa C functions. This code is
5495 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5496 the C compiler. There may be a small number of platforms on which correct
5497 operation of this code cannot be guaranteed, so the code is not used: notably,
5498 this applies to platforms where the C double format is not IEEE 754 binary64,
5499 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5500 and Python's configure script is unable to determine how to change the FPU
5501 precision. On these platforms conversions use the platform strtod and dtoa,
5502 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005503
Georg Brandlba83f822010-03-14 09:50:54 +00005504- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5505 uses the correctly-rounded string <-> float conversions described above (when
5506 available), and so produces correctly rounded results that will display nicely
5507 under the float repr. There are two related small changes: (1) round now
5508 accepts any class with an ``__index__()`` method for its second argument (but
5509 no longer accepts floats for the second argument), and (2) an excessively
5510 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5511 raises an exception.

5661 of 12. Previously, the behavior the same but with a default precision of 6.

Georg Brandlba83f822010-03-14 09:50:54 +00005804- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5805 existing .py counterpart, override the co_filename attributes of all code
5806 objects if the original filename is obsolete (which can happen if the file has

5861
Georg Brandlba83f822010-03-14 09:50:54 +00005862- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5863 file objects with closefd=False. The file descriptor is still kept open but
5864 the file object behaves like a closed file. The ``FileIO`` object also got a
5865 new readonly attribute ``closefd``.

5884
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005885- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005888- On windows, ``os.chdir()`` given unicode was not working if
5889 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5890 this code path is really executed because I cannot move to such directory on
5891 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005893- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5894 element is temporarily replaced with an equivalent frozenset. But the
5895 eventual KeyError would always report the empty ``frozenset()`` as the missing
5896 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005916- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5917 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5918 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5919 of using the replace error handler in PyUnicode_DecodeUTF8().
5920
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005921- Issue #3739: The unicode-internal encoder now reports the number of characters

5923
Georg Brandlba83f822010-03-14 09:50:54 +00005924- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5925 allocator will be automatically disabled when running under Valgrind. This
5926 gives improved memory leak detection when running under Valgrind, while taking
5927 advantage of pymalloc at other times.

7175 threads could return successfully while some Thread objects were still
7176 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00007193- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7194 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00007195 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7196 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00007201- Issue #5354: New test support function import_fresh_module() makes it easy to
7202 import both normal and optimised versions of modules. test_heapq and
7203 test_warnings have been adjusted to use it, tests for other modules with both
7204 C and Python implementations in the stdlib can be adjusted to use it over
7205 time.

Georg Brandlba83f822010-03-14 09:50:54 +00007213- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
7214 should cause a test to be skipped are now done using import_module from test
7215 support, which does the conversion.

7317
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007318- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7319 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7320 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7321 ``printf`` function, whereas PyString_FromFormat has an independent
7322 implementation and uses "%zd" on all platforms for size_t values.
7323 This makes a difference on win64, where ``printf`` needs "%Id" to display
7324 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007326- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7330 object; previously an int would be returned for small values. the __long__
7331 method is allowed to return either an int or a long, but the behaviour of
7332 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007341 was correctly parsed but parsing of subsequent arguments failed.
7342
Vinay Sajip35e3b032008-09-01 14:33:59 +00007343- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007344 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7345 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7346 when given a tuple of classes as second argument, were looking up
7347 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7348 type object.

7442
Jesse Noller438195f2009-01-18 21:04:36 +00007443- Issue #4301: Patch the logging module to add processName support, remove
7444 _check_logger_class from multiprocessing.
7445
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007446- Issue #2975: When compiling several extension modules with Visual Studio 2008
7447 from the same python interpreter, some environment variables would grow
7448 without limit.
7449
Benjamin Peterson37346b22008-08-23 20:27:43 +00007450- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7451 exploitation of poor argument checking.
7452
Gerhard Häringef2276b2008-09-12 13:54:06 +00007453- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
7454
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00007455- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
7456 remaining ones have "pysqlite_" prefix.
7457
Gerhard Häringe6872eb2008-09-12 22:33:22 +00007458- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

7466 wrapper for warnings.catch_warnings() that makes it easier to check
7467 that expected warning messages are being reported.
7468
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00007469- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007487What's New in Python 2.6 beta 3?
7488================================
7489
Barry Warsaw07a4a382008-08-21 01:15:08 +00007490*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007491
7492Core and Builtins
7493-----------------
7494
Guido van Rossumf8402962008-08-20 15:01:50 +00007495- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7496 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7497 extensions do not automatically benefit from the class attribute
7498 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7499 to their tp_flags field if they care. This is a backwards
7500 compatibility feature; in 3.0, all types will use the cache by
7501 default.
7502
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007503- Keyword arguments can now follow starred arguments. (``f(a, *args,
7504 keyword=23)`` is now valid syntax.)
7505
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007506- ctypes function pointers that are COM methods have a boolean True
7507 value again.
7508
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007509- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7510 by denying s# to parse objects that have a releasebuffer procedure,
7511 and introducing s*.
7512
Georg Brandl1e13ea92008-08-11 09:07:59 +00007513- Issue #3537: Fix an assertion failure when an empty but presized dict
7514 object was stored in the freelist.
7515
Mark Dickinsonb6467572008-08-04 21:30:09 +00007516- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7517 ValueError consistently across platforms.
7518
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007519- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7520 (64bit Unix, for example), unichr() would truncate its argument and return
7521 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7522
Neal Norwitze7d8be82008-07-31 17:17:14 +00007523- Apply security patches from Apple.
7524
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007525- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7526 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7527
Antoine Pitrou92f82162008-07-25 22:22:08 +00007528- Issue #1819: function calls with several named parameters are now on
7529 average 35% faster (as measured by pybench).
7530
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007531- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7532 the python debugger steps into a class statement: the free variables (local
7533 variables defined in an outer scope) would be deleted from the outer scope.
7534
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007535- Issue #2620: Overflow checking when allocating or reallocating memory
7536 was not always being done properly in some python types and extension
7537 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7538 all been updated to perform better checks and places in the code that
7539 would previously leak memory on the error path when such an allocation
7540 failed have been fixed.
7541
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007542Library
7543-------
7544
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007545- Issue #3612: Added some missing basic types in ctypes.wintypes.
7546
Benjamin Petersone977ad42008-08-20 01:42:01 +00007547- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7548 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7549
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007550- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7551 version reported by these tools does not necessarily follow the python
7552 version numbering scheme, so the module is less strict when parsing it.
7553
Nick Coghlanf70385a2008-08-18 12:42:46 +00007554- Issue #2235: Added Py3k warnings for types which will become unhashable
7555 under the stricter __hash__ inheritance rules in 3.0. Several types
7556 which did not meet the rules for hash invariants and were already
7557 unhashable in 3.0 have now been explicitly flagged as unhashable in
7558 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7559 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7560
Brett Cannon88f801d2008-08-18 00:46:22 +00007561- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7562 imported into the module but exposed as part of the module's API.
7563
Brett Cannon7b96f072008-08-18 00:41:11 +00007564- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7565
Brett Cannon46225e72008-08-18 00:36:52 +00007566- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7567
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007568- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7569
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007570- Issue #3575: Incremental decoder's decode function now takes bytearray
7571 by using 's*' instead of 't#'.
7572
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007573- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007574 fails unicode conversion on 2nd parameter. (windows only)
7575
Georg Brandl222e2082010-08-01 22:27:39 +00007576- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007577 in a redirect.
7578
Brett Cannonabe423e2008-08-16 21:47:07 +00007579- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007580 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007581
Facundo Batistaeb90b782008-08-16 14:44:07 +00007582- Issue #2776: fixed small issue when handling an URL with double slash
7583 after a 302 response in the case of not going through a proxy.
7584
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007585- Issue #2676: in the email package, content-type parsing was hanging on
7586 pathological input because of quadratic or exponential behaviour of a
7587 regular expression.
7588
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007589- Issue #3476: binary buffered reading through the new "io" library is now
7590 thread-safe.
7591
Brett Cannonbf3157b2008-08-14 05:00:03 +00007592- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7593 since mimetools itself is deprecated. Because modules are cached, all
7594 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7595
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007596- Issue #3134: shutil referenced undefined WindowsError symbol.
7597
Robert Schuppenies14646332008-08-10 11:01:53 +00007598- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7599 menu entries were not deleted.
7600
Brett Cannon83e81842008-08-09 23:30:55 +00007601- Copied the implementation of reduce() to _functools.reduce() to have a
7602 version that did not raise a DeprecationWarning under -3.
7603
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007604- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7605 a MemoryError rather than silently stop the iteration.
7606
Guido van Rossum59ce9012008-08-09 14:55:34 +00007607- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7608 to _sre.compile() will now be rejected. This should not affect anybody
7609 since the re.compile() function never generates invalid re-bytecode.
7610
Skip Montanaroa032bf42008-08-08 22:52:51 +00007611- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7612 upon first access it can be automatically initialized from the csv file if
7613 it wasn't initialized during instantiation.
7614
Brett Cannon3aa2a492008-08-06 22:28:09 +00007615- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7616 the reload() built-in has been removed.
7617
Brett Cannon7e30b672008-08-04 21:52:25 +00007618- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007619 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00007620 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
7621 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
7622 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
7623 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
7624 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007625
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007626- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7627 raised an AttributeError.
7628
Benjamin Peterson01a24322008-07-28 23:35:27 +00007629- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007630 asking for a specific length. This problem only affected files opened
7631 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007632
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007633- Issue #3449: Update decimal module to use most recent specification
7634 (v. 1.68) and tests (v. 2.58) from IBM.
7635
Georg Brandl222e2082010-08-01 22:27:39 +00007636- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

7640
Georg Brandlf9efabb2008-07-23 15:16:45 +00007641- Deprecate the "ast" parser function aliases.
7642
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007643- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7644
7645- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7646 invalid arguments.
7647
7648- Issue #3302: Fix several crashes when calling locale's gettext functions
7649 with None arguments.
7650
7651- Issue #3389: Allow resolving dotted names for handlers in logging
7652 configuration files.
7653

7655
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007656- Issue #3394: zipfile.writestr sets external attributes when passed a
7657 file name rather than a ZipInfo instance, so files are extracted with
7658 mode 0600 rather than 000 under Unix.
7659
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007660- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7661 argument in python 2.5, this broke code that subclassed Popen to include its
7662 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007669Documentation
7670-------------
7671
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007672- Issue #2235: the C API function PyObject_HashNotImplemented and its
7673 interaction with the tp_hash slot (added in 2.6b2) are now documented
7674
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007675- Issue #643841: The language reference now provides more detailed
7676 coverage of the lookup process for special methods. The disclaimers
7677 regarding lack of coverage of new-style classes have also been
7678 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007681What's New in Python 2.6 beta 2?
7682================================
7683
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007684*Release date: 17-Jul-2008*
7685
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007686Core and Builtins
7687-----------------
7688
Georg Brandl3e483f62008-07-16 22:57:41 +00007689- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7690 its methods now allow for items objects that can be converted to
7691 an integer using operator.index().
7692
Mark Dickinson64b7e502008-07-16 09:40:03 +00007693- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7694 produced a ValueError instead of giving the correct float.
7695
Eric Smitha5fa5a22008-07-16 00:11:49 +00007696- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7697 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7698
Mark Dickinson7103aa42008-07-15 19:08:33 +00007699- Issue #3008: the float type has a new instance method 'float.hex'
7700 and a new class method 'float.fromhex' to convert floating-point
7701 numbers to and from hexadecimal strings, respectively.
7702
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007703- Issue #2235: __hash__ is once again inherited by default. To allow
7704 collections.Hashable to remain meaningful in the presence of the
7705 default hash implementation (object.__hash__), it is now possible
7706 to explicit block inheritance of hash by setting __hash__=None at
7707 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7708 level.
7709
Nick Coghlanb028f502008-07-13 14:52:36 +00007710- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7711 the parent module cannot be found while performing an absolute import.
7712 This means that an incorrectly defined __package__ attribute will
7713 now only prevent relative imports in that module rather than causing
7714 all imports from that module to fail.
7715
Nick Coghlan14ff9942008-07-08 14:21:42 +00007716- Issue #2517: Allow unicode messages in Exceptions again by correctly
7717 bypassing the instance dictionary when looking up __unicode__ on
7718 new-style classes.
7719
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007720- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7721 set to a custom object whose write() method happens to install
7722 another file in sys.stdout.
7723
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007724- Issue #3088: Corrected a race condition in classes derived from
7725 threading.local: the first member set by a thread could be saved in
7726 another thread's dictionary.
7727
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007728- Issue #3004: Minor change to slice.indices(): the start and stop
7729 arguments are now treated identically, making the behaviour easier
7730 to describe and understand. For example, slice(None, -10,
7731 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7732 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

8184 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008185 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008186
8187 This is controlled by the configure argument ``--with-universal-archs``:
8188
8189 - ``--with-universal-archs=all``: install 4-way universal
8190
8191 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8192
8193 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8194
8195 This option should be used in combination with ``--enable-universalsdk=``.
8196
8197 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 +00008246- Issue #1631171: Re-implement the 'warnings' module in C (the
8247 original Python code has been kept as backup). This will allow for
8248 using the 'warning's machinery in such places as the parser where
8249 use of pure Python code is not possible. Both the ``showarning()``
8250 and ``formatwarning()`` gain an optional 'line' argument which is
8251 not called by default for backwards-compatibility reasons. Setting
8252 ``warnings.showwarning()`` to an implementation that lacks support
8253 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008316- Issue #2550: The approach used by client/server code for obtaining
8317 ports to listen on in network-oriented tests has been refined in an
8318 effort to facilitate running multiple instances of the entire
8319 regression test suite in parallel without issue.
8320 test_support.bind_port() has been fixed such that it will always
8321 return a unique port -- which wasn't always the case with the
8322 previous implementation, especially if socket options had been set
8323 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8324 new implementation of bind_port() will actually raise an exception
8325 if it is passed an AF_INET/SOCK_STREAM socket with either the
8326 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8327 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8328 the socket it's been passed. This currently only applies to
8329 Windows. This option prevents any other sockets from binding to the
8330 host/port we've bound to, thus removing the possibility of the
8331 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8332 when a second SOCK_STREAM socket binds and accepts to a host/port
8333 that's already been bound by another socket. The optional preferred
8334 port parameter to bind_port() has been removed. Under no
8335 circumstances should tests be hard coding ports!
8336
8337 test_support.find_unused_port() has also been introduced, which will
8338 pass a temporary socket object to bind_port() in order to obtain an
8339 unused port. The temporary socket object is then closed and
8340 deleted, and the port is returned. This method should only be used
8341 for obtaining an unused port in order to pass to an external program
8342 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8343 a parameter to a server-oriented class that doesn't give you direct
8344 access to the underlying socket used.
8345
8346 Finally, test_support.HOST has been introduced, which should be used
8347 for the host argument of any relevant socket calls (i.e. bind and
8348 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008349
8350 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008352 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8353 test_asynchat and test_socket_ssl.
8354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355 It is now possible for multiple instances of the regression test
8356 suite to run in parallel without issue.

8561 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
8563 files are used. On all linux systems the --with-system-ffi
8564 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00008625- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008626 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00008635- Added the future_builtins module, which contains hex() and oct().
8636 These are the PEP 3127 version of these functions, designed to be
8637 compatible with the hex() and oct() builtins from Python 3.0. They
8638 differ slightly in their output formats from the existing, unchanged
8639 Python 2.6 builtins. The expected usage of the future_builtins
8640 module is:
8641 from future_builtins import hex, oct
8642
Eric Smith7ef40bf2008-02-20 23:34:22 +00008643- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8644 exponents for exponents with absolute value < 100. Follows C99
8645 standard. This is a change on Windows, which would use 3 digits.
8646 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8647 so that any alterations it does to the resulting string will be
8648 available in stringlib/formatter.h (for float.__format__).
8649
Eric Smith5a3c1352008-02-19 13:21:56 +00008650- Implemented PEP 3101, Advanced String Formatting. This adds a new
8651 builtin format(); a format() method for str and unicode; a
8652 __format__() method to object, str, unicode, int, long, float, and
8653 datetime; the class string.Formatter; and the C API
8654 PyObject_Format().
8655
Georg Brandl3ee81df2008-05-17 18:14:43 +00008656- Fixed several potential crashes, all caused by specially crafted
8657 __del__ methods exploiting objects in temporarily inconsistent
8658 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008659
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008660- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008661 prevent a possible crash: an Abstract Base Class would try to access
8662 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008663

Georg Brandl3ee81df2008-05-17 18:14:43 +00008667- Clear all free lists during a gc.collect() of the highest generation
8668 in order to allow pymalloc to free more arenas. Python may give back
8669 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008670
Georg Brandl3ee81df2008-05-17 18:14:43 +00008671- Issue #2045: Fix an infinite recursion triggered when printing a
8672 subclass of collections.defaultdict, if its default_factory is set
8673 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008674
Christian Heimesf75dbef2008-02-08 00:11:31 +00008675- Fixed a minor memory leak in dictobject.c. The content of the free
8676 list was not freed on interpreter shutdown.
8677
Georg Brandl21e99f42010-03-07 15:23:59 +00008678- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008679 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008680
Georg Brandl3ee81df2008-05-17 18:14:43 +00008681- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8682 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008683 to compact the internal free lists of pre-allocted ints and floats.
8684
Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8686 calls. Python expected the return type int but the fork familie
8687 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008688
Georg Brandl3ee81df2008-05-17 18:14:43 +00008689- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8690 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008701- Patch #1473257: generator objects gain a gi_code attribute. This is
8702 the same object as the func_code attribute of the function that
8703 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008704
Georg Brandl3ee81df2008-05-17 18:14:43 +00008705- Issue #1920: "while 0" statements were completely removed by the
8706 compiler, even in the presence of an "else" clause, which is
8707 supposed to be run when the condition is false. Now the compiler
8708 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008709
Guido van Rossumeead05f2008-01-24 18:21:02 +00008710- A few crashers fixed: weakref_in_del.py (issue #1377858);
8711 loosing_dict_ref.py (issue #1303614, test67.py);
8712 borrowed_ref_[34].py (not in tracker).
8713
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008714- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008715 suppressed while an extension is loaded by calling SetErrorMode in
8716 dynload_win.c. The error is still reported properly.
8717
Georg Brandl3ee81df2008-05-17 18:14:43 +00008718- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008719 several extension methods and modules do not work without unicode
8720 support.
8721
Georg Brandl26543b12008-01-21 18:36:51 +00008722- Issue #1882: when compiling code from a string, encoding cookies in the
8723 second line of code were not always recognized correctly.
8724
Georg Brandl14404b62008-01-19 19:27:05 +00008725- Issue #1679: "0x" was taken as a valid integer literal.
8726
Georg Brandl6caad7d2008-01-26 14:19:22 +00008727- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008728 added.
8729
Christian Heimesc94e2b52008-01-14 04:13:37 +00008730- sys.float_info / PyFloat_GetInfo: The floating point information
8731 object was converted from a dict to a specialized structseq object.
8732
Georg Brandl3ee81df2008-05-17 18:14:43 +00008733- Patch #1816: Added sys.flags structseq. It exposes the status of
8734 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008735
Georg Brandl3ee81df2008-05-17 18:14:43 +00008736- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00008762 and INF. float("nan"), float("inf") and float("-inf") now work on
8763 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008764
Georg Brandl3ee81df2008-05-17 18:14:43 +00008765- Compiler now generates simpler and faster code for dictionary
8766 literals. The oparg for BUILD_MAP now indicates an estimated
8767 dictionary size. There is a new opcode, STORE_MAP, for adding
8768 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008797- Patch #1739468: Directories and zipfiles containing a __main__.py
8798 file can now be directly executed by passing their name to the
8799 interpreter. The directory/zipfile is automatically inserted as the
8800 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008802- Issue #1265: Fix a problem with sys.settrace, if the tracing
8803 function uses a generator expression when at the same time the
8804 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008805
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008806- sets and frozensets now have an isdisjoint() method.

8811
Georg Brandl21e99f42010-03-07 15:23:59 +00008812- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008813 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8814 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008815
Georg Brandl3ee81df2008-05-17 18:14:43 +00008816- Issue #1686386: Tuple's tp_repr did not take into account the
8817 possibility of having a self-referential tuple, which is possible
8818 from C code. Nor did object's tp_str consider that a type's tp_str
8819 could do something that could lead to an inifinite recursion.
8820 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8821 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008822
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823- Issue #1164: It was possible to trigger deadlock when using the
8824 'print' statement to write to a file since the GIL was not released
8825 as needed. Now PyObject_Print() does the right thing along with
8826 various tp_print implementations of the built-in types and those in
8827 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008828
Georg Brandl3ee81df2008-05-17 18:14:43 +00008829- Issue #1147: Exceptions were directly allowing string exceptions in
8830 their throw() method even though string exceptions no longer
8831 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00008835
Brett Cannon1e534b52007-09-07 04:18:30 +00008836- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008837 PyObject_Call() never calling back out to Python code to trigger
8838 recursion depth updates/checks. Required the creation of a static
8839 RuntimeError instance in case normalizing an exception put the
8840 recursion check value past its limit. Fixes crashers
8841 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008842

Neal Norwitz0ac60192007-05-27 04:08:54 +00008856- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008857 __*__ attributes. (Some already existed, e.g., __doc__ and
8858 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008859
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008860- Add -3 option to the interpreter to warn about features that are
8861 deprecated and will be changed/removed in Python 3.0.
8862
Georg Brandl2134e752007-05-21 20:34:16 +00008863- Patch #1686487: you can now pass any mapping after '**' in function
8864 calls.
8865
Collin Winter62903052007-05-18 23:11:24 +00008866- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008867 "except E as target:". This is to provide forwards compatibility
8868 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008869
Brett Cannon229cee22007-05-05 01:34:02 +00008870- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008875- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008876 setting a plain string, ie don't expand to single letter identifiers.
8877
Raymond Hettinger13936692007-04-11 18:40:58 +00008878- Request #1191699: Slices can now be pickled.
8879
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008880- Request #1193128: str.translate() now allows a None argument for
8881 translations that only remove characters without re-mapping the
8882 remaining characters.
8883
Georg Brandl5cb76c12007-03-21 09:00:39 +00008884- Patch #1682205: a TypeError while unpacking an iterable is no longer

8888
Guido van Rossum143b5642007-03-23 04:58:42 +00008889- Bug #1683368: The object.__init__() and object.__new__() methods are
8890 now stricter in rejecting excess arguments. The only time when
8891 either allows excess arguments is when it is not overridden and the
8892 other one is. For backwards compatibility, when both are
8893 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008894 warning later). Also, type.__init__() insists on the same signature
8895 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008896
Georg Brandl3ee81df2008-05-17 18:14:43 +00008897- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8898 object to complex using its __complex__() method before falling back
8899 to the __float__() method. Therefore, the functions in the cmath
8900 module now can operate on objects that define a __complex__()
8901 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008902
Georg Brandl3ee81df2008-05-17 18:14:43 +00008903- Patch #1623563: allow __class__ assignment for classes with
8904 __slots__. The old and the new class are still required to have the
8905 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008906

8911 ``object.__reduce_ex__()`` is called with an object that is faking
8912 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008913
Georg Brandl3ee81df2008-05-17 18:14:43 +00008914- Patch #1680015: Don't modify __slots__ tuple if it contains an

8918
Georg Brandl7b9c5552007-03-12 14:30:05 +00008919- Bug #1678647: write a newline after printing an exception in any
8920 case, even when converting the value to a string failed.
8921
Georg Brandl871f1bc2007-03-12 13:17:36 +00008922- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008923 its argument, if it exists. If not, it will work like before. This
8924 allows customizing the output of dir() in the presence of a
8925 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008933- Patch #1491866: change the complex() constructor to allow
8934 parthensized forms. This means complex(repr(x)) now works instead of
8935 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008936
Georg Brandlaa2321b2007-03-07 00:40:28 +00008937- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008938 makes the filenames the warning module prints much more sensible
8939 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008940
Georg Brandl49aafc92007-03-07 00:34:46 +00008941- Variant of patch #697613: don't exit the interpreter on a SystemExit
8942 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008943 variable is given, but break into the interactive interpreter just
8944 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008952- Patch #1674228: when assigning a slice (old-style), check for the
8953 sq_ass_slice instead of the sq_slice slot.
8954
Georg Brandl3ee81df2008-05-17 18:14:43 +00008955- When printing an unraisable error, don't print exceptions. before
8956 the name. This duplicates the behavior whening normally printing
8957 exceptions.

9522
Georg Brandl92a6bae2007-03-13 17:43:32 +00009523- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009524 are set for invalid interpolation sequences that would lead to

9581 TestCase and TestSuite subclasses (not instances) are no longer
9582 accepted in TestSuite.addTest(). This should cause no
9583 incompatibility since it never made sense with ordinary subclasses
9584 -- the failure just occurred later, with a more cumbersome
9585 exception.

9862 obtained from the TLS negotiation itself. Patch contributed by Bill
9863 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009864
Georg Brandl3ee81df2008-05-17 18:14:43 +00009865- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009866 that the SMTP.starttls() caller no longer needs to call ehlo()
9867 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009868 does not claim to support starttls. Adds the
9869 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9870 Fenner.

9950 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9951 silently miscode subclasses of those types. Now, it raises a
9952 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009953

Georg Brandl3ee81df2008-05-17 18:14:43 +00009968 time so that opening a database previously created with the DB_DUP
9969 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9970 opens. Specifically: dictionary assignment to a DB object will
9971 replace all values for a given key when the database allows
9972 duplicate values. DB users should use DB.put(k, v) when they want
9973 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009974

9980 characters with ASCII value less than 32. Also, it correctly quotes
9981 dots only if they occur on a single line, as opposed to the previous
9982 behavior of quoting dots if they are the second character of any
9983 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009984

Guido van Rossum7c862f82007-12-13 20:50:10 +000010252- Bug #1608: use -fwrapv when GCC supports it. This is important,
10253 newer GCC versions may optimize away overflow buffer overflow checks
10254 without this option!

10257
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010258- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +000010259 periodic threadstate and signal checking in tight loops. By
10260 default, this option is turned-off. It should only be enabled in
10261 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010262

10312
Georg Brandl3ee81df2008-05-17 18:14:43 +000010313- Unified naming convention for free lists and their limits. All free
10314 lists in Object/ are named ``free_list``, the counter ``numfree``
10315 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10316 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010317
Georg Brandl3ee81df2008-05-17 18:14:43 +000010318- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10319 to ``PyTuple_SetItem``, it can be used to populate a brand new
10320 frozenset; but it does not steal a reference to the added item.

10329
10330- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10331 ``PyFloat_GetInfo()`` to the float API.
10332
Georg Brandl3ee81df2008-05-17 18:14:43 +000010333- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10334 of w# format code incorrectly truncated the length to an int, even
10335 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10336 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010337
Georg Brandl3ee81df2008-05-17 18:14:43 +000010338- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10342 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10343 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010344
Georg Brandl3ee81df2008-05-17 18:14:43 +000010345- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10346 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010347
10348- Patch #1733960: Allow T_LONGLONG to accept ints.

10355
10356- Fix some leftovers from the conversion from int to Py_ssize_t
10357 (relevant to strings and sequences of more than 2**31 items).
10358
10359- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10360 outside of pystate.c and should not be necessary.
10361
Georg Brandl3ee81df2008-05-17 18:14:43 +000010362- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10363 absolute imports. In earlier versions they might have used relative
10364 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010365
Georg Brandl3ee81df2008-05-17 18:14:43 +000010366- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10367 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010368
Georg Brandl3ee81df2008-05-17 18:14:43 +000010369- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010375- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10376 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10377 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10378 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010379

Georg Brandl3ee81df2008-05-17 18:14:43 +000010392- Removed the macfs module. It had been deprecated since Python 2.5.
10393 This lead to the deprecation of macostools.touched() as it relied
10394 solely on macfs and was a no-op under OS X.
