Nadeem Vawda6cad3712012-11-05 00:55:06 +0100880 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +0100881 to the last call. decompressobj().flush() now correctly sets unused_data and
882 unconsumed_tail. A bug in the handling of MemoryError when setting the

Ned Deily18fae3f2013-01-31 01:24:55 -08001205- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1206 In particular, fix extension module build failures when trying to use
1207 32-bit-only installer Pythons on systems with Xcode 4 (currently
1208 OS X 10.8, 10.7, and optionally 10.6).
1209 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1210 * Since Xcode 4 removes ppc support, extension module builds now
1211 check for ppc compiler support and by default remove ppc and
1212 ppc64 archs when they are not available.
1213 * Extension module builds now revert to using system installed
1214 headers and libs (/usr and /System/Library) if the SDK used
1215 to build the interpreter is not installed or has moved.
1216 * Try to avoid building extension modules with deprecated
1217 and problematic Apple llvm-gcc compiler. If original compiler
1218 is not available, use clang instead by default.

1573 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001649- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1650 Distutils-based packages with C extension modules may fail because
1651 Apple has removed gcc-4.2, the version used to build python.org
1652 64-bit/32-bit Pythons. If the user does not explicitly override
1653 the default C compiler by setting the CC environment variable,
1654 Distutils will now attempt to compile extension modules with clang
1655 if gcc-4.2 is required but not found. Also as a convenience, if
1656 the user does explicitly set CC, substitute its value as the default
1657 compiler in the Distutils LDSHARED configuration variable for OS X.
1658 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1659 SDK, neither of which are available in Xcode 4. This change does not
1660 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001910- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1911 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1912 interpreter process. This could cause failures in non-Distutils subprocesses
1913 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001914 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001915 deployment target only in the environment of each build subprocess. It is
1916 still possible to globally override the default by setting
1917 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1918 greater or equal to the default value, the value with which the interpreter
1919 was built.

1948 updating the check interval, so if the user decreases the check interval,
1949 the ticker doesn't have to wind down to zero from the old starting point
1950 before the new interval takes effect. And if the user increases the
1951 interval, it makes sure the new limit takes effect right away rather have an
1952 early task switch before recognizing the new interval.

2916 handles non-blocking readinto() returning None correctly.
2917
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00002918- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
2919 SSLSocket.sendto() to match the corresponding socket methods. Also,
2920 fix various SSLSocket methods to raise socket.error rather than an
2921 unhelpful TypeError when called on an unconnected socket. Original patch
2922 by Andrew Bennetts.

2931
Raymond Hettinger20397532010-09-12 02:11:45 +00002932- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2933 This prevents user-created self-referencing ordered dictionaries from
2934 becoming permanently uncollectable GC garbage. The downside is that
2935 removing __del__ means that the internal doubly-linked list has to wait for
2936 GC collection rather than freeing memory immediately when the refcnt drops
2937 to zero.
2938

2942
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002943- Issue #9792: In case of connection failure, socket.create_connection()

2945 to fetch the original errno, or to filter timeout errors. Now the
2946 original error is re-raised.

2957
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002958- Issue #808164: Fixed socket.close to avoid references to globals, to

2967
R. David Murray7c4bf552010-08-25 01:45:57 +00002968- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2969 character years even if the message contains RFC822 two character years.
2970

2983 module now correctly return a set. (Patch by Eli Bendersky.)
2984
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002985- Issue #9617: Signals received during a low-level write operation aren't
2986 ignored by the buffered IO layer anymore.
2987
Benjamin Peterson52c36052010-08-21 03:03:22 +00002988- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2990
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002991- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroue1436d12010-08-12 15:25:51 +00002999- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3000 and a BadZipfile error is raised if it doesn't match (as used to be the
3001 case in Python 2.5 and earlier).

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003003- Issue #9550: a BufferedReader could issue an additional read when the
3004 original read request had been satisfied, which could block indefinitely
3005 when the underlying raw IO channel was e.g. a socket. Report and original
3006 patch by Jason V. Miller.
3007
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003008- Issue #9551: Don't raise TypeError when setting the value to None for

3399 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3400 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3412 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00003756- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003757 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3758 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3759 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3780-----------------
3781
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003782- Issue #7301: Add environment variable $PYTHONWARNINGS.
3783
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003784- Issue #8329: Don't return the same lists from select.select when no fds are
3785 changed.
3786
Georg Brandlfee0f442010-05-22 21:26:21 +00003787- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003788 on 64-bit machines. The shift count for either left or right shift is
3789 permitted to be up to sys.maxsize.
3790
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003791- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003793- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003794
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003795- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3796
Georg Brandlfee0f442010-05-22 21:26:21 +00003797- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3798 with a non-empty format string. This is an effort to future-proof user
3799 code. If a derived class does not currently implement __format__ but later
3800 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003801 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003802 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003803
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003804- Issue #8268: Old-style classes (not just instances) now support weak

3816
Victor Stinner66644262010-03-10 22:30:19 +00003817- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003818 (SIGINT). If an error occurs while importing the site module, the error is
3819 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003820 module.

3834
Georg Brandlfee0f442010-05-22 21:26:21 +00003835- Issue #8257: The Decimal construct now accepts a float instance directly,
3836 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003837
3838 >>> Decimal(1.1)
3839 Decimal('1.100000000000000088817841970012523233890533447265625')
3840
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003841- collections.Counter() now supports a subtract() method.
3842
Georg Brandlfee0f442010-05-22 21:26:21 +00003843- The functools module now has a total_ordering() class decorator to simplify
3844 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003845
Georg Brandlfee0f442010-05-22 21:26:21 +00003846- The functools module also adds cmp_to_key() as a tool to transition old-style
3847 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003848
Georg Brandlfee0f442010-05-22 21:26:21 +00003849- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3850 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003851
Georg Brandlfee0f442010-05-22 21:26:21 +00003852- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3853 InvalidOperation instead of returning False. (Comparisons involving a quiet
3854 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3855 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003856
Georg Brandlfee0f442010-05-22 21:26:21 +00003857- Issue #2531: Comparison operations between floats and Decimal instances now
3858 return a result based on the numeric values of the operands; previously they
3859 returned an arbitrary result based on the relative ordering of id(float) and
3860 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003861
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003862- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003863 argument `-` which tells it to read files to compile from stdin. Each line is
3864 read on demand and the named file is compiled immediately. (Original patch by
3865 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003866
Georg Brandlfee0f442010-05-22 21:26:21 +00003867- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003870- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3871 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003872 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003873
Georg Brandlfee0f442010-05-22 21:26:21 +00003874- Comparisons using one of <, <=, >, >= between a complex instance and a
3875 Fractions instance now raise TypeError instead of returning True/False. This
3876 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3877 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003878

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003888- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003889 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3890 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003891
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003892- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3893 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003933 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3934 log file to compute the next rollover time. If the log file does not exist,
3935 the current time is used as the basis for the computation.

3977 integer format code, struct.pack first attempts to convert the non-integer

3982 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3983 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003984 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3985 inconsistent: __int__ was used for some integer codes but not for others, and
3986 the set of integer codes for which it was used differed between native packing
3987 and standard packing.)

4219 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004220 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004239- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4240 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4241 returning NULL. The macro now returns a statically allocated empty string
4242 instead.

4252 strings,
4253 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Georg Brandlba83f822010-03-14 09:50:54 +00004288 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004294- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004295 file position when calling `truncate()`. It would previously change the file
4296 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004297 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4298
Georg Brandlba83f822010-03-14 09:50:54 +00004299- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4300 class used to represent files stored inside an archive. The new
4301 implementation is significantly faster and can be wrapped in a
4302 ``io.BufferedReader`` object for more speedups. It also solves an issue
4303 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4304 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004314- Issue #7748: Since unicode values are supported for some metadata options in
4315 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4316 encoded string for them. This ensures that the upload and register commands
4317 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004394- The ``__complex__()`` method is now looked up on the class of instances to

4402 These functions and methods now raise TypeError instead. The majority of the
4403 effects of this change are in the extension modules, but some core functions
4404 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4405 and many unicode/str methods.

4421 internal representation of a long.

4429
Georg Brandlba83f822010-03-14 09:50:54 +00004430 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004588- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4589 decimal string that's guaranteed to round back to x under correct rounding
4590 (with round-half-to-even rounding mode). Previously it gave a string based on
4591 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4592 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4593 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004594
Georg Brandlba83f822010-03-14 09:50:54 +00004595- Issue #7117: On almost all platforms: float-to-string and string-to-float
4596 conversions within Python are now correctly rounded. Places these conversions
4597 occur include: str for floats and complex numbers; the float and complex
4598 constructors; old-style and new-style numeric formatting; serialization and
4599 deserialization of floats and complex numbers using marshal, pickle and json;
4600 parsing of float and imaginary literals in Python code; Decimal-to-float
4601 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004602
Georg Brandlba83f822010-03-14 09:50:54 +00004603 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4604 providing correctly-rounded strtod and dtoa C functions. This code is
4605 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4606 the C compiler. There may be a small number of platforms on which correct
4607 operation of this code cannot be guaranteed, so the code is not used: notably,
4608 this applies to platforms where the C double format is not IEEE 754 binary64,
4609 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4610 and Python's configure script is unable to determine how to change the FPU
4611 precision. On these platforms conversions use the platform strtod and dtoa,
4612 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004614- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4615 uses the correctly-rounded string <-> float conversions described above (when
4616 available), and so produces correctly rounded results that will display nicely
4617 under the float repr. There are two related small changes: (1) round now
4618 accepts any class with an ``__index__()`` method for its second argument (but
4619 no longer accepts floats for the second argument), and (2) an excessively
4620 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4621 raises an exception.

4770 but with at least one decimal point and with a default precision
4771 of 12. Previously, the behavior the same but with a default precision of 6.
4772 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004914- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4915 existing .py counterpart, override the co_filename attributes of all code

4971
Georg Brandlba83f822010-03-14 09:50:54 +00004972- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4973 file objects with closefd=False. The file descriptor is still kept open but
4974 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004995- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004998- On windows, ``os.chdir()`` given unicode was not working if

5000 this code path is really executed because I cannot move to such directory on
5001 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005003- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5004 element is temporarily replaced with an equivalent frozenset. But the
5005 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005026- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5027 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5028 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5029 of using the replace error handler in PyUnicode_DecodeUTF8().
5030
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005031- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00005034- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5036 gives improved memory leak detection when running under Valgrind, while taking
5037 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00006284 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

6406
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006407- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6408 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6409 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6410 ``printf`` function, whereas PyString_FromFormat has an independent
6411 implementation and uses "%zd" on all platforms for size_t values.
6412 This makes a difference on win64, where ``printf`` needs "%Id" to display
6413 64bit values.

6419 object; previously an int would be returned for small values. the __long__
6420 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006430 was correctly parsed but parsing of subsequent arguments failed.
6431
Vinay Sajip35e3b032008-09-01 14:33:59 +00006432- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006433 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6434 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6435 when given a tuple of classes as second argument, were looking up
6436 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6437 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006576What's New in Python 2.6 beta 3?
6577================================
6578
Barry Warsaw07a4a382008-08-21 01:15:08 +00006579*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006580
6581Core and Builtins
6582-----------------
6583
Guido van Rossumf8402962008-08-20 15:01:50 +00006584- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6585 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6586 extensions do not automatically benefit from the class attribute
6587 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6588 to their tp_flags field if they care. This is a backwards
6589 compatibility feature; in 3.0, all types will use the cache by
6590 default.
6591
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006592- Keyword arguments can now follow starred arguments. (``f(a, *args,
6593 keyword=23)`` is now valid syntax.)
6594
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006595- ctypes function pointers that are COM methods have a boolean True
6596 value again.
6597
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006598- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6599 by denying s# to parse objects that have a releasebuffer procedure,
6600 and introducing s*.
6601
Georg Brandl1e13ea92008-08-11 09:07:59 +00006602- Issue #3537: Fix an assertion failure when an empty but presized dict
6603 object was stored in the freelist.
6604
Mark Dickinsonb6467572008-08-04 21:30:09 +00006605- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6606 ValueError consistently across platforms.
6607
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006608- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6609 (64bit Unix, for example), unichr() would truncate its argument and return
6610 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6611
Neal Norwitze7d8be82008-07-31 17:17:14 +00006612- Apply security patches from Apple.
6613
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006614- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6615 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6616
Antoine Pitrou92f82162008-07-25 22:22:08 +00006617- Issue #1819: function calls with several named parameters are now on
6618 average 35% faster (as measured by pybench).
6619
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006620- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6621 the python debugger steps into a class statement: the free variables (local
6622 variables defined in an outer scope) would be deleted from the outer scope.
6623
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006624- Issue #2620: Overflow checking when allocating or reallocating memory
6625 was not always being done properly in some python types and extension
6626 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6627 all been updated to perform better checks and places in the code that
6628 would previously leak memory on the error path when such an allocation
6629 failed have been fixed.
6630
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006631Library
6632-------
6633
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006634- Issue #3612: Added some missing basic types in ctypes.wintypes.
6635
Benjamin Petersone977ad42008-08-20 01:42:01 +00006636- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6637 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6638
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006639- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6640 version reported by these tools does not necessarily follow the python
6641 version numbering scheme, so the module is less strict when parsing it.
6642
Nick Coghlanf70385a2008-08-18 12:42:46 +00006643- Issue #2235: Added Py3k warnings for types which will become unhashable
6644 under the stricter __hash__ inheritance rules in 3.0. Several types
6645 which did not meet the rules for hash invariants and were already
6646 unhashable in 3.0 have now been explicitly flagged as unhashable in
6647 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6648 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6649
Brett Cannon88f801d2008-08-18 00:46:22 +00006650- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6651 imported into the module but exposed as part of the module's API.
6652
Brett Cannon7b96f072008-08-18 00:41:11 +00006653- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6654
Brett Cannon46225e72008-08-18 00:36:52 +00006655- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6656
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006657- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6658
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006659- Issue #3575: Incremental decoder's decode function now takes bytearray
6660 by using 's*' instead of 't#'.
6661
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006662- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006663 fails unicode conversion on 2nd parameter. (windows only)
6664
Georg Brandl222e2082010-08-01 22:27:39 +00006665- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006666 in a redirect.
6667
Brett Cannonabe423e2008-08-16 21:47:07 +00006668- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006669 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006670
Facundo Batistaeb90b782008-08-16 14:44:07 +00006671- Issue #2776: fixed small issue when handling an URL with double slash
6672 after a 302 response in the case of not going through a proxy.
6673
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006674- Issue #2676: in the email package, content-type parsing was hanging on
6675 pathological input because of quadratic or exponential behaviour of a
6676 regular expression.
6677
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006678- Issue #3476: binary buffered reading through the new "io" library is now
6679 thread-safe.
6680
Brett Cannonbf3157b2008-08-14 05:00:03 +00006681- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6682 since mimetools itself is deprecated. Because modules are cached, all
6683 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6684
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006685- Issue #3134: shutil referenced undefined WindowsError symbol.
6686
Robert Schuppenies14646332008-08-10 11:01:53 +00006687- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6688 menu entries were not deleted.
6689
Brett Cannon83e81842008-08-09 23:30:55 +00006690- Copied the implementation of reduce() to _functools.reduce() to have a
6691 version that did not raise a DeprecationWarning under -3.
6692
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006693- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6694 a MemoryError rather than silently stop the iteration.
6695
Guido van Rossum59ce9012008-08-09 14:55:34 +00006696- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6697 to _sre.compile() will now be rejected. This should not affect anybody
6698 since the re.compile() function never generates invalid re-bytecode.
6699
Skip Montanaroa032bf42008-08-08 22:52:51 +00006700- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6701 upon first access it can be automatically initialized from the csv file if
6702 it wasn't initialized during instantiation.
6703
Brett Cannon3aa2a492008-08-06 22:28:09 +00006704- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6705 the reload() built-in has been removed.
6706
Brett Cannon7e30b672008-08-04 21:52:25 +00006707- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006708 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6710 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6711 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6712 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6713 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006714
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006715- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6716 raised an AttributeError.
6717
Benjamin Peterson01a24322008-07-28 23:35:27 +00006718- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006719 asking for a specific length. This problem only affected files opened
6720 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006721
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006722- Issue #3449: Update decimal module to use most recent specification
6723 (v. 1.68) and tests (v. 2.58) from IBM.
6724
Georg Brandl222e2082010-08-01 22:27:39 +00006725- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006726
Georg Brandl222e2082010-08-01 22:27:39 +00006727- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00006728 on a closed shelf.
6729
Georg Brandlf9efabb2008-07-23 15:16:45 +00006730- Deprecate the "ast" parser function aliases.
6731
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006732- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6733
6734- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6735 invalid arguments.
6736
6737- Issue #3302: Fix several crashes when calling locale's gettext functions
6738 with None arguments.
6739
6740- Issue #3389: Allow resolving dotted names for handlers in logging
6741 configuration files.
6742
6743- Deprecate the sunaudio module for removal in Python 3.0.
6744
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006745- Issue #3394: zipfile.writestr sets external attributes when passed a
6746 file name rather than a ZipInfo instance, so files are extracted with
6747 mode 0600 rather than 000 under Unix.
6748
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006749- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6750 argument in python 2.5, this broke code that subclassed Popen to include its
6751 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6760
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006761- Issue #2235: the C API function PyObject_HashNotImplemented and its
6762 interaction with the tp_hash slot (added in 2.6b2) are now documented
6763
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006764- Issue #643841: The language reference now provides more detailed
6765 coverage of the lookup process for special methods. The disclaimers
6766 regarding lack of coverage of new-style classes have also been
6767 removed, since the coverage is now fairly reasonable.

6771================================
6772
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006773*Release date: 17-Jul-2008*
6774
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006775Core and Builtins
6776-----------------
6777
Georg Brandl3e483f62008-07-16 22:57:41 +00006778- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6779 its methods now allow for items objects that can be converted to
6780 an integer using operator.index().
6781
Mark Dickinson64b7e502008-07-16 09:40:03 +00006782- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6783 produced a ValueError instead of giving the correct float.
6784
Eric Smitha5fa5a22008-07-16 00:11:49 +00006785- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6786 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6787
Mark Dickinson7103aa42008-07-15 19:08:33 +00006788- Issue #3008: the float type has a new instance method 'float.hex'
6789 and a new class method 'float.fromhex' to convert floating-point
6790 numbers to and from hexadecimal strings, respectively.
6791
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006792- Issue #2235: __hash__ is once again inherited by default. To allow
6793 collections.Hashable to remain meaningful in the presence of the
6794 default hash implementation (object.__hash__), it is now possible
6795 to explicit block inheritance of hash by setting __hash__=None at
6796 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6797 level.
6798
Nick Coghlanb028f502008-07-13 14:52:36 +00006799- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6800 the parent module cannot be found while performing an absolute import.
6801 This means that an incorrectly defined __package__ attribute will
6802 now only prevent relative imports in that module rather than causing
6803 all imports from that module to fail.
6804
Nick Coghlan14ff9942008-07-08 14:21:42 +00006805- Issue #2517: Allow unicode messages in Exceptions again by correctly
6806 bypassing the instance dictionary when looking up __unicode__ on
6807 new-style classes.
6808
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006809- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6810 set to a custom object whose write() method happens to install
6811 another file in sys.stdout.
6812
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006813- Issue #3088: Corrected a race condition in classes derived from
6814 threading.local: the first member set by a thread could be saved in
6815 another thread's dictionary.
6816
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006817- Issue #3004: Minor change to slice.indices(): the start and stop
6818 arguments are now treated identically, making the behaviour easier
6819 to describe and understand. For example, slice(None, -10,
6820 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6821 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6822 10, -1).
6823
Georg Brandl278fc502008-07-19 12:46:12 +00006824- Issue #3219: Calling a function with repeated keyword arguments,
6825 f(a=2, a=23), would not cause a syntax error. This was a regression
6826 from 2.4 caused by the switch to the new compiler.

6836 api functions without holding the GIL, which could lead to a fatal
6837 error when they failed.
6838
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006839- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00007276 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007277
7278 This is controlled by the configure argument ``--with-universal-archs``:
7279
7280 - ``--with-universal-archs=all``: install 4-way universal
7281
7282 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7283
7284 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7285
7286 This option should be used in combination with ``--enable-universalsdk=``.
7287
7288 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 +00007338- Issue #1631171: Re-implement the 'warnings' module in C (the
7339 original Python code has been kept as backup). This will allow for
7340 using the 'warning's machinery in such places as the parser where
7341 use of pure Python code is not possible. Both the ``showarning()``
7342 and ``formatwarning()`` gain an optional 'line' argument which is
7343 not called by default for backwards-compatibility reasons. Setting
7344 ``warnings.showwarning()`` to an implementation that lacks support
7345 for the ``line`` argument will raise a DeprecationWarning.

7393 file.close() is called while an object is in use by another thread
7394 an IOError exception will be raised and the file will not be closed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007400- Issue #2385: distutils.core.run_script() makes __file__ available,
7401 so the controlled environment will more closely mirror the typical
7402 script environment. This supports setup.py scripts that refer to
7403 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Issue #2550: The approach used by client/server code for obtaining
7409 ports to listen on in network-oriented tests has been refined in an
7410 effort to facilitate running multiple instances of the entire
7411 regression test suite in parallel without issue.
7412 test_support.bind_port() has been fixed such that it will always
7413 return a unique port -- which wasn't always the case with the
7414 previous implementation, especially if socket options had been set
7415 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7416 new implementation of bind_port() will actually raise an exception
7417 if it is passed an AF_INET/SOCK_STREAM socket with either the
7418 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7419 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7420 the socket it's been passed. This currently only applies to
7421 Windows. This option prevents any other sockets from binding to the
7422 host/port we've bound to, thus removing the possibility of the
7423 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7424 when a second SOCK_STREAM socket binds and accepts to a host/port
7425 that's already been bound by another socket. The optional preferred
7426 port parameter to bind_port() has been removed. Under no
7427 circumstances should tests be hard coding ports!
7428
7429 test_support.find_unused_port() has also been introduced, which will
7430 pass a temporary socket object to bind_port() in order to obtain an
7431 unused port. The temporary socket object is then closed and
7432 deleted, and the port is returned. This method should only be used
7433 for obtaining an unused port in order to pass to an external program
7434 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7435 a parameter to a server-oriented class that doesn't give you direct
7436 access to the underlying socket used.
7437
7438 Finally, test_support.HOST has been introduced, which should be used
7439 for the host argument of any relevant socket calls (i.e. bind and
7440 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007441
7442 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007444 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7445 test_asynchat and test_socket_ssl.
7446
Georg Brandl3ee81df2008-05-17 18:14:43 +00007447 It is now possible for multiple instances of the regression test
7448 suite to run in parallel without issue.

7716
Fred Drakea8ee94b2008-03-01 02:45:07 +00007717- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007718 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +00007726
Eric Smitha73fbe72008-02-23 03:09:44 +00007727- Added the future_builtins module, which contains hex() and oct().
7728 These are the PEP 3127 version of these functions, designed to be
7729 compatible with the hex() and oct() builtins from Python 3.0. They
7730 differ slightly in their output formats from the existing, unchanged
7731 Python 2.6 builtins. The expected usage of the future_builtins
7732 module is:
7733 from future_builtins import hex, oct
7734
Eric Smith7ef40bf2008-02-20 23:34:22 +00007735- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7736 exponents for exponents with absolute value < 100. Follows C99
7737 standard. This is a change on Windows, which would use 3 digits.
7738 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7739 so that any alterations it does to the resulting string will be
7740 available in stringlib/formatter.h (for float.__format__).
7741
Eric Smith5a3c1352008-02-19 13:21:56 +00007742- Implemented PEP 3101, Advanced String Formatting. This adds a new
7743 builtin format(); a format() method for str and unicode; a
7744 __format__() method to object, str, unicode, int, long, float, and
7745 datetime; the class string.Formatter; and the C API
7746 PyObject_Format().
7747
Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Fixed several potential crashes, all caused by specially crafted
7749 __del__ methods exploiting objects in temporarily inconsistent
7750 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007751
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007752- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753 prevent a possible crash: an Abstract Base Class would try to access
7754 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007755
Georg Brandl3ee81df2008-05-17 18:14:43 +00007756- Fixed repr() and str() of complex numbers with infinity or nan as
7757 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- Clear all free lists during a gc.collect() of the highest generation
7760 in order to allow pymalloc to free more arenas. Python may give back
7761 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007762
Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Issue #2045: Fix an infinite recursion triggered when printing a
7764 subclass of collections.defaultdict, if its default_factory is set
7765 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007766
Christian Heimesf75dbef2008-02-08 00:11:31 +00007767- Fixed a minor memory leak in dictobject.c. The content of the free
7768 list was not freed on interpreter shutdown.
7769
Georg Brandl21e99f42010-03-07 15:23:59 +00007770- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007771 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007772
Georg Brandl3ee81df2008-05-17 18:14:43 +00007773- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7774 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007775 to compact the internal free lists of pre-allocted ints and floats.
7776
Georg Brandl3ee81df2008-05-17 18:14:43 +00007777- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7778 calls. Python expected the return type int but the fork familie
7779 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007780
Georg Brandl3ee81df2008-05-17 18:14:43 +00007781- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7782 appear in the same code unit.

7791 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007792
Georg Brandl3ee81df2008-05-17 18:14:43 +00007793- Patch #1473257: generator objects gain a gi_code attribute. This is
7794 the same object as the func_code attribute of the function that
7795 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007796
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797- Issue #1920: "while 0" statements were completely removed by the
7798 compiler, even in the presence of an "else" clause, which is
7799 supposed to be run when the condition is false. Now the compiler
7800 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007801
Guido van Rossumeead05f2008-01-24 18:21:02 +00007802- A few crashers fixed: weakref_in_del.py (issue #1377858);
7803 loosing_dict_ref.py (issue #1303614, test67.py);
7804 borrowed_ref_[34].py (not in tracker).
7805
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007806- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007807 suppressed while an extension is loaded by calling SetErrorMode in
7808 dynload_win.c. The error is still reported properly.
7809
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007811 several extension methods and modules do not work without unicode
7812 support.
7813
Georg Brandl26543b12008-01-21 18:36:51 +00007814- Issue #1882: when compiling code from a string, encoding cookies in the
7815 second line of code were not always recognized correctly.
7816
Georg Brandl14404b62008-01-19 19:27:05 +00007817- Issue #1679: "0x" was taken as a valid integer literal.
7818
Georg Brandl6caad7d2008-01-26 14:19:22 +00007819- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007820 added.
7821
Christian Heimesc94e2b52008-01-14 04:13:37 +00007822- sys.float_info / PyFloat_GetInfo: The floating point information
7823 object was converted from a dict to a specialized structseq object.
7824
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825- Patch #1816: Added sys.flags structseq. It exposes the status of
7826 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007827
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Objects/structseq.c: Implemented new structseq representation. The
7829 patch makes structseqs (e.g. the return value of os.stat) more
7830 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007831
Georg Brandl3ee81df2008-05-17 18:14:43 +00007832- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007844- Improve some exception messages when Windows fails to load an
7845 extension module. Now we get for example '%1 is not a valid Win32
7846 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007854 and INF. float("nan"), float("inf") and float("-inf") now work on
7855 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007856
Georg Brandl3ee81df2008-05-17 18:14:43 +00007857- Compiler now generates simpler and faster code for dictionary
7858 literals. The oparg for BUILD_MAP now indicates an estimated
7859 dictionary size. There is a new opcode, STORE_MAP, for adding
7860 entries to the dictionary.

Neal Norwitz44f326e2007-10-05 05:29:17 +00007902- Fix warnings found by the new version of the Coverity checker.
7903
Georg Brandl21e99f42010-03-07 15:23:59 +00007904- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007905 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7906 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007907
Georg Brandl3ee81df2008-05-17 18:14:43 +00007908- Issue #1686386: Tuple's tp_repr did not take into account the
7909 possibility of having a self-referential tuple, which is possible
7910 from C code. Nor did object's tp_str consider that a type's tp_str
7911 could do something that could lead to an inifinite recursion.
7912 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7913 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007914
Georg Brandl3ee81df2008-05-17 18:14:43 +00007915- Issue #1164: It was possible to trigger deadlock when using the
7916 'print' statement to write to a file since the GIL was not released
7917 as needed. Now PyObject_Print() does the right thing along with
7918 various tp_print implementations of the built-in types and those in
7919 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007920
Georg Brandl3ee81df2008-05-17 18:14:43 +00007921- Issue #1147: Exceptions were directly allowing string exceptions in
7922 their throw() method even though string exceptions no longer
7923 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Issue #1096: Prevent a segfault from getting the repr of a very
7926 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007927
Brett Cannon1e534b52007-09-07 04:18:30 +00007928- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007929 PyObject_Call() never calling back out to Python code to trigger
7930 recursion depth updates/checks. Required the creation of a static
7931 RuntimeError instance in case normalizing an exception put the
7932 recursion check value past its limit. Fixes crashers
7933 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007934
Georg Brandl3ee81df2008-05-17 18:14:43 +00007935- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007948- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007949 __*__ attributes. (Some already existed, e.g., __doc__ and
7950 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007951
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007952- Add -3 option to the interpreter to warn about features that are
7953 deprecated and will be changed/removed in Python 3.0.
7954
Georg Brandl2134e752007-05-21 20:34:16 +00007955- Patch #1686487: you can now pass any mapping after '**' in function
7956 calls.
7957
Collin Winter62903052007-05-18 23:11:24 +00007958- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007959 "except E as target:". This is to provide forwards compatibility
7960 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007961
Brett Cannon229cee22007-05-05 01:34:02 +00007962- Deprecate BaseException.message as per PEP 352.
7963
Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007965 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007966
Vinay Sajip8549ce32007-05-06 17:53:37 +00007967- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007968 setting a plain string, ie don't expand to single letter identifiers.
7969
Raymond Hettinger13936692007-04-11 18:40:58 +00007970- Request #1191699: Slices can now be pickled.
7971
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007972- Request #1193128: str.translate() now allows a None argument for
7973 translations that only remove characters without re-mapping the
7974 remaining characters.
7975
Georg Brandl5cb76c12007-03-21 09:00:39 +00007976- Patch #1682205: a TypeError while unpacking an iterable is no longer
7977 masked by a generic one with the message "unpack non-sequence".
7978
Neal Norwitzaa754b72007-03-21 06:39:48 +00007979- Remove unused file Python/fmod.c.
7980
Guido van Rossum143b5642007-03-23 04:58:42 +00007981- Bug #1683368: The object.__init__() and object.__new__() methods are
7982 now stricter in rejecting excess arguments. The only time when
7983 either allows excess arguments is when it is not overridden and the
7984 other one is. For backwards compatibility, when both are
7985 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007986 warning later). Also, type.__init__() insists on the same signature
7987 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007988
Georg Brandl3ee81df2008-05-17 18:14:43 +00007989- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7990 object to complex using its __complex__() method before falling back
7991 to the __float__() method. Therefore, the functions in the cmath
7992 module now can operate on objects that define a __complex__()
7993 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Patch #1623563: allow __class__ assignment for classes with
7996 __slots__. The old and the new class are still required to have the
7997 same slot names.

8003 ``object.__reduce_ex__()`` is called with an object that is faking
8004 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- Patch #1680015: Don't modify __slots__ tuple if it contains an

8010
Georg Brandl7b9c5552007-03-12 14:30:05 +00008011- Bug #1678647: write a newline after printing an exception in any
8012 case, even when converting the value to a string failed.
8013
Georg Brandl871f1bc2007-03-12 13:17:36 +00008014- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008015 its argument, if it exists. If not, it will work like before. This
8016 allows customizing the output of dir() in the presence of a
8017 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008018
Collin Winter276887b2007-03-12 16:11:39 +00008019- Patch #922167: Python no longer segfaults when faced with infinitely
8020 self-recursive reload() calls (as reported by bug #742342).
8021

Georg Brandl3ee81df2008-05-17 18:14:43 +00008025- Patch #1491866: change the complex() constructor to allow
8026 parthensized forms. This means complex(repr(x)) now works instead of
8027 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008028
Georg Brandlaa2321b2007-03-07 00:40:28 +00008029- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030 makes the filenames the warning module prints much more sensible
8031 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008032
Georg Brandl49aafc92007-03-07 00:34:46 +00008033- Variant of patch #697613: don't exit the interpreter on a SystemExit
8034 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035 variable is given, but break into the interactive interpreter just
8036 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008044- Patch #1674228: when assigning a slice (old-style), check for the
8045 sq_ass_slice instead of the sq_slice slot.
8046
Georg Brandl3ee81df2008-05-17 18:14:43 +00008047- When printing an unraisable error, don't print exceptions. before
8048 the name. This duplicates the behavior whening normally printing
8049 exceptions.

8678 exception.

8951 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008952
Georg Brandl3ee81df2008-05-17 18:14:43 +00008953- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8954 with RFC 3207 and forgets any knowledge obtained from the server not
8955 obtained from the TLS negotiation itself. Patch contributed by Bill
8956 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008957
Georg Brandl3ee81df2008-05-17 18:14:43 +00008958- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008959 that the SMTP.starttls() caller no longer needs to call ehlo()
8960 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961 does not claim to support starttls. Adds the
8962 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8963 Fenner.

9043 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9044 silently miscode subclasses of those types. Now, it raises a
9045 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009046

Georg Brandl3ee81df2008-05-17 18:14:43 +00009061 time so that opening a database previously created with the DB_DUP
9062 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9063 opens. Specifically: dictionary assignment to a DB object will
9064 replace all values for a given key when the database allows
9065 duplicate values. DB users should use DB.put(k, v) when they want
9066 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009067

9073 characters with ASCII value less than 32. Also, it correctly quotes
9074 dots only if they occur on a single line, as opposed to the previous
9075 behavior of quoting dots if they are the second character of any
9076 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009077

9373 returned by python-config if Python was built with --enable-shared
9374 because that prevented the shared library from being used.

9408-----
9409
Georg Brandl3ee81df2008-05-17 18:14:43 +00009410- Unified naming convention for free lists and their limits. All free
9411 lists in Object/ are named ``free_list``, the counter ``numfree``
9412 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9413 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009414
Georg Brandl3ee81df2008-05-17 18:14:43 +00009415- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9416 to ``PyTuple_SetItem``, it can be used to populate a brand new
9417 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009418
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009419- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

9422 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9423 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009424
9425- Patch #1720595: add T_BOOL to the range of structmember types.
9426
9427- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9428 ``PyFloat_GetInfo()`` to the float API.
9429
Georg Brandl3ee81df2008-05-17 18:14:43 +00009430- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9431 of w# format code incorrectly truncated the length to an int, even
9432 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9433 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009434
Georg Brandl3ee81df2008-05-17 18:14:43 +00009435- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9436 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009438- PEP 3123: Provide forward compatibility with Python 3.0, while
9439 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9440 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009441

9443 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009444
9445- Patch #1733960: Allow T_LONGLONG to accept ints.

9452
9453- Fix some leftovers from the conversion from int to Py_ssize_t
9454 (relevant to strings and sequences of more than 2**31 items).
9455
9456- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9457 outside of pystate.c and should not be necessary.
9458
Georg Brandl3ee81df2008-05-17 18:14:43 +00009459- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9460 absolute imports. In earlier versions they might have used relative
9461 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009462
Georg Brandl3ee81df2008-05-17 18:14:43 +00009463- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9464 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009465
Georg Brandl3ee81df2008-05-17 18:14:43 +00009466- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009473- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9474 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9475 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9476 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009477

Georg Brandl3ee81df2008-05-17 18:14:43 +00009491- Removed the macfs module. It had been deprecated since Python 2.5.
9492 This lead to the deprecation of macostools.touched() as it relied
9493 solely on macfs and was a no-op under OS X.
