Ned Deily18fae3f2013-01-31 01:24:55 -08001184- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1185 In particular, fix extension module build failures when trying to use
1186 32-bit-only installer Pythons on systems with Xcode 4 (currently
1187 OS X 10.8, 10.7, and optionally 10.6).
1188 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1189 * Since Xcode 4 removes ppc support, extension module builds now
1190 check for ppc compiler support and by default remove ppc and
1191 ppc64 archs when they are not available.
1192 * Extension module builds now revert to using system installed
1193 headers and libs (/usr and /System/Library) if the SDK used
1194 to build the interpreter is not installed or has moved.
1195 * Try to avoid building extension modules with deprecated
1196 and problematic Apple llvm-gcc compiler. If original compiler
1197 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001548- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1549 int.__pow__. These overflow checks were causing int.__pow__ to produce
1550 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001551 compiler optimizing the check away. Also fix similar overflow checks
1552 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001622 has left two versions of customize_compiler, the original in
1623 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001628- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1629 Distutils-based packages with C extension modules may fail because
1630 Apple has removed gcc-4.2, the version used to build python.org
1631 64-bit/32-bit Pythons. If the user does not explicitly override
1632 the default C compiler by setting the CC environment variable,
1633 Distutils will now attempt to compile extension modules with clang
1634 if gcc-4.2 is required but not found. Also as a convenience, if
1635 the user does explicitly set CC, substitute its value as the default
1636 compiler in the Distutils LDSHARED configuration variable for OS X.
1637 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1638 SDK, neither of which are available in Xcode 4. This change does not
1639 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001889- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1890 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1891 interpreter process. This could cause failures in non-Distutils subprocesses
1892 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001893 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001894 deployment target only in the environment of each build subprocess. It is
1895 still possible to globally override the default by setting
1896 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1897 greater or equal to the default value, the value with which the interpreter
1898 was built.

1928 the ticker doesn't have to wind down to zero from the old starting point
1929 before the new interval takes effect. And if the user increases the
1930 interval, it makes sure the new limit takes effect right away rather have an
1931 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002911- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2912 This prevents user-created self-referencing ordered dictionaries from
2913 becoming permanently uncollectable GC garbage. The downside is that
2914 removing __del__ means that the internal doubly-linked list has to wait for
2915 GC collection rather than freeing memory immediately when the refcnt drops
2916 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003375- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3376 start byte and the continuation byte(s) are now considered invalid, instead
3377 of the number of bytes specified by the start byte.
3378 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3379 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3380 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3390 objects. (1) The comparison could incorrectly return True in some cases
3391 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3392 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003736 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3737 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3738 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3758Core and Builtins
3759-----------------
3760
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003761- Issue #7301: Add environment variable $PYTHONWARNINGS.
3762
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003763- Issue #8329: Don't return the same lists from select.select when no fds are
3764 changed.
3765
Georg Brandlfee0f442010-05-22 21:26:21 +00003766- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003767 on 64-bit machines. The shift count for either left or right shift is
3768 permitted to be up to sys.maxsize.
3769
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003770- Ensure that tokenization of identifiers is not affected by locale.
3771
Georg Brandlfee0f442010-05-22 21:26:21 +00003772- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003773
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003774- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3775
Georg Brandlfee0f442010-05-22 21:26:21 +00003776- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3777 with a non-empty format string. This is an effort to future-proof user
3778 code. If a derived class does not currently implement __format__ but later
3779 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003780 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003781 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003782
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003783- Issue #8268: Old-style classes (not just instances) now support weak

3792 arguments to a function correct.
3793
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003794- Issue #8164: Don't allow lambda functions to have a docstring.
3795
Victor Stinner66644262010-03-10 22:30:19 +00003796- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003797 (SIGINT). If an error occurs while importing the site module, the error is
3798 printed and Python exits. Initialize the GIL before importing the site

3813
Georg Brandlfee0f442010-05-22 21:26:21 +00003814- Issue #8257: The Decimal construct now accepts a float instance directly,
3815 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003816
3817 >>> Decimal(1.1)
3818 Decimal('1.100000000000000088817841970012523233890533447265625')
3819
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003820- collections.Counter() now supports a subtract() method.
3821
Georg Brandlfee0f442010-05-22 21:26:21 +00003822- The functools module now has a total_ordering() class decorator to simplify
3823 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003824
Georg Brandlfee0f442010-05-22 21:26:21 +00003825- The functools module also adds cmp_to_key() as a tool to transition old-style
3826 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003827
Georg Brandlfee0f442010-05-22 21:26:21 +00003828- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3829 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003830
Georg Brandlfee0f442010-05-22 21:26:21 +00003831- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3832 InvalidOperation instead of returning False. (Comparisons involving a quiet
3833 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3834 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003835
Georg Brandlfee0f442010-05-22 21:26:21 +00003836- Issue #2531: Comparison operations between floats and Decimal instances now
3837 return a result based on the numeric values of the operands; previously they
3838 returned an arbitrary result based on the relative ordering of id(float) and
3839 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003840
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003841- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003842 argument `-` which tells it to read files to compile from stdin. Each line is
3843 read on demand and the named file is compiled immediately. (Original patch by
3844 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003845
Georg Brandlfee0f442010-05-22 21:26:21 +00003846- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003849- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3850 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003851 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003852
Georg Brandlfee0f442010-05-22 21:26:21 +00003853- Comparisons using one of <, <=, >, >= between a complex instance and a
3854 Fractions instance now raise TypeError instead of returning True/False. This
3855 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3856 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003857

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003867- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003868 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3869 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003870
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003871- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3872 deprecated.

3965 the set of integer codes for which it was used differed between native packing
3966 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00004197- Issue #5677: Explicitly forbid write operations on read-only file objects,
4198 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004199 library would return a bogus result; on Solaris, it was possible to crash the
4200 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00004213- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4214 and add the additional members returned in an OSVERSIONINFOEX structure. The
4215 new members are service_pack_major, service_pack_minor, suite_mask, and
4216 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00004218- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4219 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4220 returning NULL. The macro now returns a statically allocated empty string
4221 instead.

4231 strings,
4232 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4233 numeric strings corresponding to subnormal values,
4234 (3) a memory leak for some values large enough to cause overflow, and
4235 (4) a number of flaws that could lead to incorrectly rounded results.
4236

4253 interpreter shutdown.
4254
Georg Brandlba83f822010-03-14 09:50:54 +00004255- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4256 XML processing instructions and comments. These raw characters are allowed
4257 by the XML specification, and are necessary when outputting e.g. PHP code in
4258 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00004266- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004267 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004268 Also, raise ValueError rather than TypeError when an unknown TIPC address
4269 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004273- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004274 file position when calling `truncate()`. It would previously change the file
4275 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004276 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4277
Georg Brandlba83f822010-03-14 09:50:54 +00004278- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4279 class used to represent files stored inside an archive. The new
4280 implementation is significantly faster and can be wrapped in a
4281 ``io.BufferedReader`` object for more speedups. It also solves an issue
4282 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4283 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00004284
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004285- Issue #7792: Registering non-classes to ABCs raised an obscure error.

4291 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004292
Georg Brandlba83f822010-03-14 09:50:54 +00004293- Issue #7748: Since unicode values are supported for some metadata options in
4294 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4295 encoded string for them. This ensures that the upload and register commands
4296 send the correct values to PyPI without any error.

4372
Georg Brandlba83f822010-03-14 09:50:54 +00004373- The ``__complex__()`` method is now looked up on the class of instances to
4374 make it consistent with other special methods.

4378
Mark Dickinson1b34d252010-01-01 17:27:30 +00004379- Issue #5080: A number of functions and methods previously produced a

4381 These functions and methods now raise TypeError instead. The majority of the
4382 effects of this change are in the extension modules, but some core functions
4383 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4384 and many unicode/str methods.

4408
Georg Brandlba83f822010-03-14 09:50:54 +00004409 These executables now work properly with the arch(1) command: ``arch -ppc
4410 python`` will start a universal binary version of python in PPC mode (unlike

4551 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004552

4554 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004566
Georg Brandlba83f822010-03-14 09:50:54 +00004567- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4568 decimal string that's guaranteed to round back to x under correct rounding
4569 (with round-half-to-even rounding mode). Previously it gave a string based on
4570 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4571 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4572 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004573
Georg Brandlba83f822010-03-14 09:50:54 +00004574- Issue #7117: On almost all platforms: float-to-string and string-to-float
4575 conversions within Python are now correctly rounded. Places these conversions
4576 occur include: str for floats and complex numbers; the float and complex
4577 constructors; old-style and new-style numeric formatting; serialization and
4578 deserialization of floats and complex numbers using marshal, pickle and json;
4579 parsing of float and imaginary literals in Python code; Decimal-to-float
4580 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004581
Georg Brandlba83f822010-03-14 09:50:54 +00004582 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4583 providing correctly-rounded strtod and dtoa C functions. This code is
4584 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4585 the C compiler. There may be a small number of platforms on which correct
4586 operation of this code cannot be guaranteed, so the code is not used: notably,
4587 this applies to platforms where the C double format is not IEEE 754 binary64,
4588 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4589 and Python's configure script is unable to determine how to change the FPU
4590 precision. On these platforms conversions use the platform strtod and dtoa,
4591 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004592
Georg Brandlba83f822010-03-14 09:50:54 +00004593- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4594 uses the correctly-rounded string <-> float conversions described above (when
4595 available), and so produces correctly rounded results that will display nicely
4596 under the float repr. There are two related small changes: (1) round now
4597 accepts any class with an ``__index__()`` method for its second argument (but
4598 no longer accepts floats for the second argument), and (2) an excessively
4599 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4600 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004747- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4748 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4749 but with at least one decimal point and with a default precision
4750 of 12. Previously, the behavior the same but with a default precision of 6.
4751 This more closely matches ``str()``, and reduces surprises when adding
4752 alignment flags to the empty presentation type. This also affects the new
4753 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00004901- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
4902 file with `str' filename on Windows.
4903
Antoine Pitrouaa687902009-01-01 14:11:22 +00004904- Issue #3680: Reference cycles created through a dict, set or deque iterator
4905 did not get collected.
4906
Georg Brandlba83f822010-03-14 09:50:54 +00004907- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
4908 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00004909
Benjamin Peterson7af65562008-12-29 17:56:58 +00004910- Issue #4764: With io.open, IOError.filename is set when trying to open a
4911 directory on POSIX systems.
4912
Benjamin Petersonfe231b02008-12-29 17:47:42 +00004913- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
4914 systems.
4915
Georg Brandl6425a2f2008-12-28 11:54:53 +00004916- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004917 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004918
Skip Montanarof205c132008-12-23 03:30:15 +00004919- Added test case to ensure attempts to read from a file opened for writing
4920 fail.
4921
Georg Brandlba83f822010-03-14 09:50:54 +00004922- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4923 elapsed times, not only when some objects are uncollectable/unreachable.
4924 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00004936- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4937 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4938 instances. On a typical machine this saves 3 bytes of memory (on average) per
4939 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004940
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004941- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4942 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4943 instead of throwing a MemoryError.
4944
Georg Brandlba83f822010-03-14 09:50:54 +00004945- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4946 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004947
Benjamin Petersonc078f922008-11-21 22:27:24 +00004948- Issue #4367: Python would segfault during compiling when the unicodedata
4949 module couldn't be imported and \N escapes were present.
4950
Georg Brandlba83f822010-03-14 09:50:54 +00004951- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4952 file objects with closefd=False. The file descriptor is still kept open but
4953 the file object behaves like a closed file. The ``FileIO`` object also got a
4954 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004955
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004956- Issue #4348: Some bytearray methods returned that didn't cause any change to
4957 the bytearray, returned the same bytearray instead of a copy.
4958
Georg Brandlba83f822010-03-14 09:50:54 +00004959- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00004961- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4962
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004963- Issue #4048: The parser module now correctly validates relative imports.
4964
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004965- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4966 exec statement.
4967
Georg Brandlba83f822010-03-14 09:50:54 +00004968- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4969 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004970
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004971- Issue #4209: Enabling unicode_literals and the print_function in the same
4972 __future__ import didn't work.
4973
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004974- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004975 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004976
Georg Brandlba83f822010-03-14 09:50:54 +00004977- On windows, ``os.chdir()`` given unicode was not working if
4978 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4979 this code path is really executed because I cannot move to such directory on
4980 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004981
Georg Brandlba83f822010-03-14 09:50:54 +00004982- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4983 element is temporarily replaced with an equivalent frozenset. But the
4984 eventual KeyError would always report the empty ``frozenset()`` as the missing
4985 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004986
Georg Brandlba83f822010-03-14 09:50:54 +00004987- Issue #4509: Various issues surrounding resize of bytearray objects to which
4988 there are buffer exports.

4995
Georg Brandlba83f822010-03-14 09:50:54 +00004996- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00004999- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5000 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005001
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005002- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5003 returned them on 64bit platforms.
5004
Walter Dörwalded960ac2009-05-03 22:36:33 +00005005- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5006 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5007 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5008 of using the replace error handler in PyUnicode_DecodeUTF8().
5009
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005010- Issue #3739: The unicode-internal encoder now reports the number of characters
5011 consumed like any other encoder (instead of the number of bytes).
5012
Georg Brandlba83f822010-03-14 09:50:54 +00005013- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5014 allocator will be automatically disabled when running under Valgrind. This
5015 gives improved memory leak detection when running under Valgrind, while taking
5016 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006261- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6262 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006263 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6264 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006269- Issue #5354: New test support function import_fresh_module() makes it easy to
6270 import both normal and optimised versions of modules. test_heapq and
6271 test_warnings have been adjusted to use it, tests for other modules with both
6272 C and Python implementations in the stdlib can be adjusted to use it over
6273 time.

6282 should cause a test to be skipped are now done using import_module from test
6283 support, which does the conversion.

6385
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006386- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6387 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6388 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6389 ``printf`` function, whereas PyString_FromFormat has an independent
6390 implementation and uses "%zd" on all platforms for size_t values.
6391 This makes a difference on win64, where ``printf`` needs "%Id" to display
6392 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006394- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6398 object; previously an int would be returned for small values. the __long__
6399 method is allowed to return either an int or a long, but the behaviour of
6400 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006409 was correctly parsed but parsing of subsequent arguments failed.
6410
Vinay Sajip35e3b032008-09-01 14:33:59 +00006411- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006412 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6413 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6414 when given a tuple of classes as second argument, were looking up
6415 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6416 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006555What's New in Python 2.6 beta 3?
6556================================
6557
Barry Warsaw07a4a382008-08-21 01:15:08 +00006558*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006559
6560Core and Builtins
6561-----------------
6562
Guido van Rossumf8402962008-08-20 15:01:50 +00006563- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6564 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6565 extensions do not automatically benefit from the class attribute
6566 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6567 to their tp_flags field if they care. This is a backwards
6568 compatibility feature; in 3.0, all types will use the cache by
6569 default.
6570
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006571- Keyword arguments can now follow starred arguments. (``f(a, *args,
6572 keyword=23)`` is now valid syntax.)
6573
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006574- ctypes function pointers that are COM methods have a boolean True
6575 value again.
6576
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006577- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6578 by denying s# to parse objects that have a releasebuffer procedure,
6579 and introducing s*.
6580
Georg Brandl1e13ea92008-08-11 09:07:59 +00006581- Issue #3537: Fix an assertion failure when an empty but presized dict
6582 object was stored in the freelist.
6583
Mark Dickinsonb6467572008-08-04 21:30:09 +00006584- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6585 ValueError consistently across platforms.
6586
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006587- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6588 (64bit Unix, for example), unichr() would truncate its argument and return
6589 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6590
Neal Norwitze7d8be82008-07-31 17:17:14 +00006591- Apply security patches from Apple.
6592
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006593- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6594 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6595
Antoine Pitrou92f82162008-07-25 22:22:08 +00006596- Issue #1819: function calls with several named parameters are now on
6597 average 35% faster (as measured by pybench).
6598
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006599- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6600 the python debugger steps into a class statement: the free variables (local
6601 variables defined in an outer scope) would be deleted from the outer scope.
6602
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006603- Issue #2620: Overflow checking when allocating or reallocating memory
6604 was not always being done properly in some python types and extension
6605 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6606 all been updated to perform better checks and places in the code that
6607 would previously leak memory on the error path when such an allocation
6608 failed have been fixed.
6609
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006610Library
6611-------
6612
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006613- Issue #3612: Added some missing basic types in ctypes.wintypes.
6614
Benjamin Petersone977ad42008-08-20 01:42:01 +00006615- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6616 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6617
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006618- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6619 version reported by these tools does not necessarily follow the python
6620 version numbering scheme, so the module is less strict when parsing it.
6621
Nick Coghlanf70385a2008-08-18 12:42:46 +00006622- Issue #2235: Added Py3k warnings for types which will become unhashable
6623 under the stricter __hash__ inheritance rules in 3.0. Several types
6624 which did not meet the rules for hash invariants and were already
6625 unhashable in 3.0 have now been explicitly flagged as unhashable in
6626 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6627 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6628
Brett Cannon88f801d2008-08-18 00:46:22 +00006629- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6630 imported into the module but exposed as part of the module's API.
6631
Brett Cannon7b96f072008-08-18 00:41:11 +00006632- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6633
Brett Cannon46225e72008-08-18 00:36:52 +00006634- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6635
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006636- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6637
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006638- Issue #3575: Incremental decoder's decode function now takes bytearray
6639 by using 's*' instead of 't#'.
6640
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006641- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006642 fails unicode conversion on 2nd parameter. (windows only)
6643
Georg Brandl222e2082010-08-01 22:27:39 +00006644- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006645 in a redirect.
6646
Brett Cannonabe423e2008-08-16 21:47:07 +00006647- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006648 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006649
Facundo Batistaeb90b782008-08-16 14:44:07 +00006650- Issue #2776: fixed small issue when handling an URL with double slash
6651 after a 302 response in the case of not going through a proxy.
6652
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006653- Issue #2676: in the email package, content-type parsing was hanging on
6654 pathological input because of quadratic or exponential behaviour of a
6655 regular expression.
6656
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006657- Issue #3476: binary buffered reading through the new "io" library is now
6658 thread-safe.
6659
Brett Cannonbf3157b2008-08-14 05:00:03 +00006660- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6661 since mimetools itself is deprecated. Because modules are cached, all
6662 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6663
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006664- Issue #3134: shutil referenced undefined WindowsError symbol.
6665
Robert Schuppenies14646332008-08-10 11:01:53 +00006666- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6667 menu entries were not deleted.
6668
Brett Cannon83e81842008-08-09 23:30:55 +00006669- Copied the implementation of reduce() to _functools.reduce() to have a
6670 version that did not raise a DeprecationWarning under -3.
6671
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006672- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6673 a MemoryError rather than silently stop the iteration.
6674
Guido van Rossum59ce9012008-08-09 14:55:34 +00006675- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6676 to _sre.compile() will now be rejected. This should not affect anybody
6677 since the re.compile() function never generates invalid re-bytecode.
6678
Skip Montanaroa032bf42008-08-08 22:52:51 +00006679- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6680 upon first access it can be automatically initialized from the csv file if
6681 it wasn't initialized during instantiation.
6682
Brett Cannon3aa2a492008-08-06 22:28:09 +00006683- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6684 the reload() built-in has been removed.
6685
Brett Cannon7e30b672008-08-04 21:52:25 +00006686- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006687 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006688 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6689 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6690 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6691 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6692 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006693
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006694- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6695 raised an AttributeError.
6696
Benjamin Peterson01a24322008-07-28 23:35:27 +00006697- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006698 asking for a specific length. This problem only affected files opened
6699 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006700
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006701- Issue #3449: Update decimal module to use most recent specification
6702 (v. 1.68) and tests (v. 2.58) from IBM.
6703
Georg Brandl222e2082010-08-01 22:27:39 +00006704- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006705

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006707 on a closed shelf.
6708
Georg Brandlf9efabb2008-07-23 15:16:45 +00006709- Deprecate the "ast" parser function aliases.
6710
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006711- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6712
6713- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6714 invalid arguments.
6715
6716- Issue #3302: Fix several crashes when calling locale's gettext functions
6717 with None arguments.
6718
6719- Issue #3389: Allow resolving dotted names for handlers in logging
6720 configuration files.
6721
6722- Deprecate the sunaudio module for removal in Python 3.0.
6723
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006724- Issue #3394: zipfile.writestr sets external attributes when passed a
6725 file name rather than a ZipInfo instance, so files are extracted with
6726 mode 0600 rather than 000 under Unix.
6727
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006728- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6729 argument in python 2.5, this broke code that subclassed Popen to include its
6730 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6738-------------
6739
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006740- Issue #2235: the C API function PyObject_HashNotImplemented and its
6741 interaction with the tp_hash slot (added in 2.6b2) are now documented
6742
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006743- Issue #643841: The language reference now provides more detailed
6744 coverage of the lookup process for special methods. The disclaimers
6745 regarding lack of coverage of new-style classes have also been
6746 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006749What's New in Python 2.6 beta 2?
6750================================
6751
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006752*Release date: 17-Jul-2008*
6753
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006754Core and Builtins
6755-----------------
6756
Georg Brandl3e483f62008-07-16 22:57:41 +00006757- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6758 its methods now allow for items objects that can be converted to
6759 an integer using operator.index().
6760
Mark Dickinson64b7e502008-07-16 09:40:03 +00006761- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6762 produced a ValueError instead of giving the correct float.
6763
Eric Smitha5fa5a22008-07-16 00:11:49 +00006764- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6765 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6766
Mark Dickinson7103aa42008-07-15 19:08:33 +00006767- Issue #3008: the float type has a new instance method 'float.hex'
6768 and a new class method 'float.fromhex' to convert floating-point
6769 numbers to and from hexadecimal strings, respectively.
6770
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006771- Issue #2235: __hash__ is once again inherited by default. To allow
6772 collections.Hashable to remain meaningful in the presence of the
6773 default hash implementation (object.__hash__), it is now possible
6774 to explicit block inheritance of hash by setting __hash__=None at
6775 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6776 level.
6777
Nick Coghlanb028f502008-07-13 14:52:36 +00006778- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6779 the parent module cannot be found while performing an absolute import.
6780 This means that an incorrectly defined __package__ attribute will
6781 now only prevent relative imports in that module rather than causing
6782 all imports from that module to fail.
6783
Nick Coghlan14ff9942008-07-08 14:21:42 +00006784- Issue #2517: Allow unicode messages in Exceptions again by correctly
6785 bypassing the instance dictionary when looking up __unicode__ on
6786 new-style classes.
6787
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006788- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6789 set to a custom object whose write() method happens to install
6790 another file in sys.stdout.
6791
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006792- Issue #3088: Corrected a race condition in classes derived from
6793 threading.local: the first member set by a thread could be saved in
6794 another thread's dictionary.
6795
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006796- Issue #3004: Minor change to slice.indices(): the start and stop
6797 arguments are now treated identically, making the behaviour easier
6798 to describe and understand. For example, slice(None, -10,
6799 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6800 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6801 10, -1).
6802
Georg Brandl278fc502008-07-19 12:46:12 +00006803- Issue #3219: Calling a function with repeated keyword arguments,
6804 f(a=2, a=23), would not cause a syntax error. This was a regression
6805 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006806
Georg Brandl278fc502008-07-19 12:46:12 +00006807- Issue #2862: Make int and float freelist management consistent with
6808 other freelists. Changes their CompactFreeList apis into
6809 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006810

6813
Thomas Heller57adf222008-08-14 19:10:48 +00006814- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6815 api functions without holding the GIL, which could lead to a fatal
6816 error when they failed.
6817
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006818- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6827 ForkingPickler.register() to resolve conflict with ctypes.
6828
Vinay Sajip51e65192008-07-18 09:01:10 +00006829- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6832 a valid dlerror() message.
6833
Thomas Heller2bad6572008-07-15 17:19:50 +00006834- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6835 incomplete structure was created.
6836

7254 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007255 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007256
7257 This is controlled by the configure argument ``--with-universal-archs``:
7258
7259 - ``--with-universal-archs=all``: install 4-way universal
7260
7261 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7262
7263 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7264
7265 This option should be used in combination with ``--enable-universalsdk=``.
7266

Georg Brandl3ee81df2008-05-17 18:14:43 +00007317- Issue #1631171: Re-implement the 'warnings' module in C (the
7318 original Python code has been kept as backup). This will allow for
7319 using the 'warning's machinery in such places as the parser where
7320 use of pure Python code is not possible. Both the ``showarning()``
7321 and ``formatwarning()`` gain an optional 'line' argument which is
7322 not called by default for backwards-compatibility reasons. Setting
7323 ``warnings.showwarning()`` to an implementation that lacks support
7324 for the ``line`` argument will raise a DeprecationWarning.

7348
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007349- The getpass module has been improved on Unix. It now uses /dev/tty
7350 by default and uses stderr instead of stdout. A GetPassWarning is
7351 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007366- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007367 extension modules between 32 and 64 bit platforms. See the distutls

7389 effort to facilitate running multiple instances of the entire
7390 regression test suite in parallel without issue.
7391 test_support.bind_port() has been fixed such that it will always
7392 return a unique port -- which wasn't always the case with the
7393 previous implementation, especially if socket options had been set
7394 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7395 new implementation of bind_port() will actually raise an exception
7396 if it is passed an AF_INET/SOCK_STREAM socket with either the
7397 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7398 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7399 the socket it's been passed. This currently only applies to
7400 Windows. This option prevents any other sockets from binding to the
7401 host/port we've bound to, thus removing the possibility of the
7402 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7403 when a second SOCK_STREAM socket binds and accepts to a host/port
7404 that's already been bound by another socket. The optional preferred
7405 port parameter to bind_port() has been removed. Under no
7406 circumstances should tests be hard coding ports!
7407
7408 test_support.find_unused_port() has also been introduced, which will
7409 pass a temporary socket object to bind_port() in order to obtain an
7410 unused port. The temporary socket object is then closed and
7411 deleted, and the port is returned. This method should only be used
7412 for obtaining an unused port in order to pass to an external program
7413 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7414 a parameter to a server-oriented class that doesn't give you direct
7415 access to the underlying socket used.
7416
7417 Finally, test_support.HOST has been introduced, which should be used
7418 for the host argument of any relevant socket calls (i.e. bind and
7419 connect).

7421 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007422 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007423 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7424 test_asynchat and test_socket_ssl.
7425
Georg Brandl3ee81df2008-05-17 18:14:43 +00007426 It is now possible for multiple instances of the regression test
7427 suite to run in parallel without issue.

7695
Fred Drakea8ee94b2008-03-01 02:45:07 +00007696- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007697 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007698
Georg Brandlad61bc82008-02-23 15:11:18 +00007699- Issue #2067: file.__exit__() now calls subclasses' close() method.
7700
7701- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007702
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007703- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007704 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007705
Eric Smitha73fbe72008-02-23 03:09:44 +00007706- Added the future_builtins module, which contains hex() and oct().
7707 These are the PEP 3127 version of these functions, designed to be
7708 compatible with the hex() and oct() builtins from Python 3.0. They
7709 differ slightly in their output formats from the existing, unchanged
7710 Python 2.6 builtins. The expected usage of the future_builtins
7711 module is:
7712 from future_builtins import hex, oct
7713
Eric Smith7ef40bf2008-02-20 23:34:22 +00007714- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7715 exponents for exponents with absolute value < 100. Follows C99
7716 standard. This is a change on Windows, which would use 3 digits.
7717 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7718 so that any alterations it does to the resulting string will be
7719 available in stringlib/formatter.h (for float.__format__).
7720
Eric Smith5a3c1352008-02-19 13:21:56 +00007721- Implemented PEP 3101, Advanced String Formatting. This adds a new
7722 builtin format(); a format() method for str and unicode; a
7723 __format__() method to object, str, unicode, int, long, float, and
7724 datetime; the class string.Formatter; and the C API
7725 PyObject_Format().
7726
Georg Brandl3ee81df2008-05-17 18:14:43 +00007727- Fixed several potential crashes, all caused by specially crafted
7728 __del__ methods exploiting objects in temporarily inconsistent
7729 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007730
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007731- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732 prevent a possible crash: an Abstract Base Class would try to access
7733 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735- Fixed repr() and str() of complex numbers with infinity or nan as
7736 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007737
Georg Brandl3ee81df2008-05-17 18:14:43 +00007738- Clear all free lists during a gc.collect() of the highest generation
7739 in order to allow pymalloc to free more arenas. Python may give back
7740 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007741
Georg Brandl3ee81df2008-05-17 18:14:43 +00007742- Issue #2045: Fix an infinite recursion triggered when printing a
7743 subclass of collections.defaultdict, if its default_factory is set
7744 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007745
Christian Heimesf75dbef2008-02-08 00:11:31 +00007746- Fixed a minor memory leak in dictobject.c. The content of the free
7747 list was not freed on interpreter shutdown.
7748
Georg Brandl21e99f42010-03-07 15:23:59 +00007749- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007751
Georg Brandl3ee81df2008-05-17 18:14:43 +00007752- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7753 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007754 to compact the internal free lists of pre-allocted ints and floats.
7755
Georg Brandl3ee81df2008-05-17 18:14:43 +00007756- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7757 calls. Python expected the return type int but the fork familie
7758 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007759
Georg Brandl3ee81df2008-05-17 18:14:43 +00007760- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7761 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007762
Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7764 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007765
Georg Brandl3ee81df2008-05-17 18:14:43 +00007766- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7767 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007768
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7770 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007771
Georg Brandl3ee81df2008-05-17 18:14:43 +00007772- Patch #1473257: generator objects gain a gi_code attribute. This is
7773 the same object as the func_code attribute of the function that
7774 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007775
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776- Issue #1920: "while 0" statements were completely removed by the
7777 compiler, even in the presence of an "else" clause, which is
7778 supposed to be run when the condition is false. Now the compiler
7779 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007780
Guido van Rossumeead05f2008-01-24 18:21:02 +00007781- A few crashers fixed: weakref_in_del.py (issue #1377858);
7782 loosing_dict_ref.py (issue #1303614, test67.py);
7783 borrowed_ref_[34].py (not in tracker).
7784
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007785- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007786 suppressed while an extension is loaded by calling SetErrorMode in
7787 dynload_win.c. The error is still reported properly.
7788
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007790 several extension methods and modules do not work without unicode
7791 support.
7792
Georg Brandl26543b12008-01-21 18:36:51 +00007793- Issue #1882: when compiling code from a string, encoding cookies in the
7794 second line of code were not always recognized correctly.
7795
Georg Brandl14404b62008-01-19 19:27:05 +00007796- Issue #1679: "0x" was taken as a valid integer literal.
7797
Georg Brandl6caad7d2008-01-26 14:19:22 +00007798- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007799 added.
7800
Christian Heimesc94e2b52008-01-14 04:13:37 +00007801- sys.float_info / PyFloat_GetInfo: The floating point information
7802 object was converted from a dict to a specialized structseq object.
7803
Georg Brandl3ee81df2008-05-17 18:14:43 +00007804- Patch #1816: Added sys.flags structseq. It exposes the status of
7805 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007806
Georg Brandl3ee81df2008-05-17 18:14:43 +00007807- Objects/structseq.c: Implemented new structseq representation. The
7808 patch makes structseqs (e.g. the return value of os.stat) more
7809 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007810
Georg Brandl3ee81df2008-05-17 18:14:43 +00007811- Patch #1700288: added a type attribute cache that caches method
7812 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007813
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007814- Bug #1776: __import__() no longer accepts filenames on any platform.
7815 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007816

7818
Georg Brandl3ee81df2008-05-17 18:14:43 +00007819- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7820 envvar and sys.dont_write_bytecode attribute. All these can be set
7821 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007822
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Improve some exception messages when Windows fails to load an
7824 extension module. Now we get for example '%1 is not a valid Win32
7825 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Bug #1481296: Fixed long(float('nan')) != 0L.

7830 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007831
Christian Heimes0a8143f2007-12-18 23:22:54 +00007832- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007833 and INF. float("nan"), float("inf") and float("-inf") now work on
7834 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007835
Georg Brandl3ee81df2008-05-17 18:14:43 +00007836- Compiler now generates simpler and faster code for dictionary
7837 literals. The oparg for BUILD_MAP now indicates an estimated
7838 dictionary size. There is a new opcode, STORE_MAP, for adding
7839 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007873- Issue #1265: Fix a problem with sys.settrace, if the tracing
7874 function uses a generator expression when at the same time the
7875 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007876
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007877- sets and frozensets now have an isdisjoint() method.

7882
Georg Brandl21e99f42010-03-07 15:23:59 +00007883- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007884 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7885 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007886
Georg Brandl3ee81df2008-05-17 18:14:43 +00007887- Issue #1686386: Tuple's tp_repr did not take into account the
7888 possibility of having a self-referential tuple, which is possible
7889 from C code. Nor did object's tp_str consider that a type's tp_str
7890 could do something that could lead to an inifinite recursion.
7891 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7892 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007894- Issue #1164: It was possible to trigger deadlock when using the
7895 'print' statement to write to a file since the GIL was not released
7896 as needed. Now PyObject_Print() does the right thing along with
7897 various tp_print implementations of the built-in types and those in
7898 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007899
Georg Brandl3ee81df2008-05-17 18:14:43 +00007900- Issue #1147: Exceptions were directly allowing string exceptions in
7901 their throw() method even though string exceptions no longer
7902 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007903
Georg Brandl3ee81df2008-05-17 18:14:43 +00007904- Issue #1096: Prevent a segfault from getting the repr of a very
7905 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007906
Brett Cannon1e534b52007-09-07 04:18:30 +00007907- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007908 PyObject_Call() never calling back out to Python code to trigger
7909 recursion depth updates/checks. Required the creation of a static
7910 RuntimeError instance in case normalizing an exception put the
7911 recursion check value past its limit. Fixes crashers
7912 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007913
Georg Brandl3ee81df2008-05-17 18:14:43 +00007914- Patch #1031213: Decode source line in SyntaxErrors back to its
7915 original source encoding.

7918 with %G.
7919
Georg Brandl3ee81df2008-05-17 18:14:43 +00007920- Prevent expandtabs() on string and unicode objects from causing a
7921 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007922
Georg Brandl3ee81df2008-05-17 18:14:43 +00007923- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00007924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00007926
Neal Norwitz0ac60192007-05-27 04:08:54 +00007927- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928 __*__ attributes. (Some already existed, e.g., __doc__ and
7929 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007930
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007931- Add -3 option to the interpreter to warn about features that are
7932 deprecated and will be changed/removed in Python 3.0.
7933
Georg Brandl2134e752007-05-21 20:34:16 +00007934- Patch #1686487: you can now pass any mapping after '**' in function
7935 calls.
7936
Collin Winter62903052007-05-18 23:11:24 +00007937- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007938 "except E as target:". This is to provide forwards compatibility
7939 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007940
Brett Cannon229cee22007-05-05 01:34:02 +00007941- Deprecate BaseException.message as per PEP 352.
7942
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007944 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007945
Vinay Sajip8549ce32007-05-06 17:53:37 +00007946- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007947 setting a plain string, ie don't expand to single letter identifiers.
7948
Raymond Hettinger13936692007-04-11 18:40:58 +00007949- Request #1191699: Slices can now be pickled.
7950
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007951- Request #1193128: str.translate() now allows a None argument for
7952 translations that only remove characters without re-mapping the
7953 remaining characters.
7954
Georg Brandl5cb76c12007-03-21 09:00:39 +00007955- Patch #1682205: a TypeError while unpacking an iterable is no longer
7956 masked by a generic one with the message "unpack non-sequence".
7957
Neal Norwitzaa754b72007-03-21 06:39:48 +00007958- Remove unused file Python/fmod.c.
7959
Guido van Rossum143b5642007-03-23 04:58:42 +00007960- Bug #1683368: The object.__init__() and object.__new__() methods are
7961 now stricter in rejecting excess arguments. The only time when
7962 either allows excess arguments is when it is not overridden and the
7963 other one is. For backwards compatibility, when both are
7964 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007965 warning later). Also, type.__init__() insists on the same signature
7966 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007967
Georg Brandl3ee81df2008-05-17 18:14:43 +00007968- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7969 object to complex using its __complex__() method before falling back
7970 to the __float__() method. Therefore, the functions in the cmath
7971 module now can operate on objects that define a __complex__()
7972 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007973
Georg Brandl3ee81df2008-05-17 18:14:43 +00007974- Patch #1623563: allow __class__ assignment for classes with
7975 __slots__. The old and the new class are still required to have the
7976 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007977
Georg Brandl3ee81df2008-05-17 18:14:43 +00007978- Patch #1642547: Fix an error/crash when encountering syntax errors
7979 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007981- Patch #1462488: Python no longer segfaults when
7982 ``object.__reduce_ex__()`` is called with an object that is faking
7983 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007984
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Patch #1680015: Don't modify __slots__ tuple if it contains an
7986 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00007987
Georg Brandl5240d742007-03-13 20:46:32 +00007988- Patch #1444529: the builtin compile() now accepts keyword arguments.
7989
Georg Brandl7b9c5552007-03-12 14:30:05 +00007990- Bug #1678647: write a newline after printing an exception in any
7991 case, even when converting the value to a string failed.
7992
Georg Brandl871f1bc2007-03-12 13:17:36 +00007993- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994 its argument, if it exists. If not, it will work like before. This
7995 allows customizing the output of dir() in the presence of a
7996 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007997
Collin Winter276887b2007-03-12 16:11:39 +00007998- Patch #922167: Python no longer segfaults when faced with infinitely
7999 self-recursive reload() calls (as reported by bug #742342).
8000
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001- Patch #1675981: remove unreachable code from ``type.__new__()``
8002 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Patch #1491866: change the complex() constructor to allow
8005 parthensized forms. This means complex(repr(x)) now works instead of
8006 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008007
Georg Brandlaa2321b2007-03-07 00:40:28 +00008008- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009 makes the filenames the warning module prints much more sensible
8010 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008011
Georg Brandl49aafc92007-03-07 00:34:46 +00008012- Variant of patch #697613: don't exit the interpreter on a SystemExit
8013 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014 variable is given, but break into the interactive interpreter just
8015 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00008016
Georg Brandl3ee81df2008-05-17 18:14:43 +00008017- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Bug #1674503: close the file opened by execfile() in an error
8021 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008022
Georg Brandl0fca97a2007-03-05 22:28:08 +00008023- Patch #1674228: when assigning a slice (old-style), check for the
8024 sq_ass_slice instead of the sq_slice slot.
8025
Georg Brandl3ee81df2008-05-17 18:14:43 +00008026- When printing an unraisable error, don't print exceptions. before
8027 the name. This duplicates the behavior whening normally printing
8028 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008029
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008036- Bug #1377858: Fix the segfaulting of the interpreter when an object
8037 created a weakref on itself during a __del__ call for new-style
8038 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008039
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008040- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
8041 frame's thread state.

Georg Brandl2c1375c2006-10-12 11:27:59 +00008078- Bug #1545497: when given an explicit base, int() did ignore NULs
8079 embedded in the string to convert.
8080
Georg Brandl846f73a2006-10-08 07:11:54 +00008081- Bug #1569998: break inside a try statement (outside a loop) is now
8082 recognized and rejected.
8083

8085
Armin Rigo7ccbca92006-10-04 12:17:45 +00008086- A number of places, including integer negation and absolute value,
8087 were fixed to not rely on undefined behaviour of the C compiler
8088 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00008089

8091 number of arguments, as was the case in Python 2.4.
8092
Georg Brandl5d59c092006-09-30 08:43:30 +00008093- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00008094 keyword arguments any more (previously they accepted them, but
8095 didn't use them).
Georg Brandl5d59c092006-09-30 08:43:30 +00008096
Georg Brandl3ee81df2008-05-17 18:14:43 +00008097- Fix a bug in the parser's future statement handling that led to
8098 "with" not being recognized as a keyword after, e.g., this
8099 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00008100

8108 method. This allows calling unicode() on exceptions classes
8109 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00008110
Georg Brandl4e933132006-09-06 20:05:58 +00008111- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8117
Tim Petersc10c9d02006-09-05 02:18:09 +00008118- Overflow checking code in integer division ran afoul of new gcc
8119 optimizations. Changed to be more standard-conforming.

8126 head is the original string if sep was not found.
8127
Neal Norwitzdac090d2006-09-05 03:53:08 +00008128- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008129 generator expressions (x for x, in ... ) works again. Fixing this
8130 problem required changing the .pyc magic number. This means that
8131 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00008132

8637 Python would crash instead of raising an error.

8656 -- the failure just occurred later, with a more cumbersome
8657 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00008868- ctypes callback functions only support 'fundamental' data types as

Georg Brandl3ee81df2008-05-17 18:14:43 +00008902- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't

8930 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008931
Georg Brandl3ee81df2008-05-17 18:14:43 +00008932- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8933 with RFC 3207 and forgets any knowledge obtained from the server not
8934 obtained from the TLS negotiation itself. Patch contributed by Bill
8935 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008936
Georg Brandl3ee81df2008-05-17 18:14:43 +00008937- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008938 that the SMTP.starttls() caller no longer needs to call ehlo()
8939 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008940 does not claim to support starttls. Adds the
8941 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8942 Fenner.

9022 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9023 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009040 time so that opening a database previously created with the DB_DUP
9041 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9042 opens. Specifically: dictionary assignment to a DB object will
9043 replace all values for a given key when the database allows
9044 duplicate values. DB users should use DB.put(k, v) when they want
9045 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009046

9052 characters with ASCII value less than 32. Also, it correctly quotes
9053 dots only if they occur on a single line, as opposed to the previous
9054 behavior of quoting dots if they are the second character of any
9055 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009056

9387-----
9388
Georg Brandl3ee81df2008-05-17 18:14:43 +00009389- Unified naming convention for free lists and their limits. All free
9390 lists in Object/ are named ``free_list``, the counter ``numfree``
9391 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9392 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009393
Georg Brandl3ee81df2008-05-17 18:14:43 +00009394- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9395 to ``PyTuple_SetItem``, it can be used to populate a brand new
9396 frozenset; but it does not steal a reference to the added item.

9401 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9402 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009403
9404- Patch #1720595: add T_BOOL to the range of structmember types.
9405
9406- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9407 ``PyFloat_GetInfo()`` to the float API.
9408
Georg Brandl3ee81df2008-05-17 18:14:43 +00009409- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9410 of w# format code incorrectly truncated the length to an int, even
9411 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9412 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009413
Georg Brandl3ee81df2008-05-17 18:14:43 +00009414- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9415 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009417- PEP 3123: Provide forward compatibility with Python 3.0, while
9418 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9419 and PyVarObject_HEAD_INIT.

9422 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009423
9424- Patch #1733960: Allow T_LONGLONG to accept ints.

9432- Fix some leftovers from the conversion from int to Py_ssize_t
9433 (relevant to strings and sequences of more than 2**31 items).
9434
9435- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9436 outside of pystate.c and should not be necessary.
9437
Georg Brandl3ee81df2008-05-17 18:14:43 +00009438- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9439 absolute imports. In earlier versions they might have used relative
9440 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009441
Georg Brandl3ee81df2008-05-17 18:14:43 +00009442- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9443 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009444
Georg Brandl3ee81df2008-05-17 18:14:43 +00009445- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009452- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9453 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9454 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9455 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009456

Georg Brandl3ee81df2008-05-17 18:14:43 +00009470- Removed the macfs module. It had been deprecated since Python 2.5.
9471 This lead to the deprecation of macostools.touched() as it relied
9472 solely on macfs and was a no-op under OS X.
