408 SSLSocket.sendto() to match the corresponding socket methods. Also,
409 fix various SSLSocket methods to raise socket.error rather than an
410 unhelpful TypeError when called on an unconnected socket. Original patch
411 by Andrew Bennetts.

420
Raymond Hettinger20397532010-09-12 02:11:45 +0000421- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
422 This prevents user-created self-referencing ordered dictionaries from
423 becoming permanently uncollectable GC garbage. The downside is that
424 removing __del__ means that the internal doubly-linked list has to wait for
425 GC collection rather than freeing memory immediately when the refcnt drops
426 to zero.
427
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000428- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

431
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000432- Issue #9792: In case of connection failure, socket.create_connection()
433 would swallow the exception and raise a new one, making it impossible
434 to fetch the original errno, or to filter timeout errors. Now the
435 original error is re-raised.
436
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000437- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
438 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
439 be updated back after the system call. Original patch by Brian Brazil.
440

445 ConfigParser.write.
446
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000447- Issue #808164: Fixed socket.close to avoid references to globals, to
448 avoid issues when socket.close is called from a __del__ method.
449
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000450- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

455 falling into recursion.
456
R. David Murray7c4bf552010-08-25 01:45:57 +0000457- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
458 character years even if the message contains RFC822 two character years.
459
Daniel Stutzbach91287322010-08-24 21:09:30 +0000460- Issue #8750: Fixed MutableSet's methods to correctly handle
461 reflexive operations, namely x -= x and x ^= x.
462

472 module now correctly return a set. (Patch by Eli Bendersky.)
473
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000474- Issue #9617: Signals received during a low-level write operation aren't
475 ignored by the buffered IO layer anymore.
476
Benjamin Peterson52c36052010-08-21 03:03:22 +0000477- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
478 are not held onto after they are deleted elsewhere.
479
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000480- Issue #9626: the view methods for collections.OrderedDict() were returning
481 the unordered versions inherited from dict. Those methods are now
482 overridden to provide ordered views.
483
Éric Araujo0389ae62010-08-14 03:07:46 +0000484- Issue #8688: MANIFEST files created by distutils now include a magic
485 comment indicating they are generated. Manually maintained MANIFESTs
486 without this marker will not be overwritten or removed.
487
Antoine Pitroue1436d12010-08-12 15:25:51 +0000488- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
489 and a BadZipfile error is raised if it doesn't match (as used to be the
490 case in Python 2.5 and earlier).
491
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000492- Issue #9550: a BufferedReader could issue an additional read when the
493 original read request had been satisfied, which could block indefinitely
494 when the underlying raw IO channel was e.g. a socket. Report and original
495 patch by Jason V. Miller.
496
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000497- Issue #9551: Don't raise TypeError when setting the value to None for

499
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000500- Issue #6915: Under Windows, os.listdir() didn't release the Global

516 This is how it is supposed to work, wget and curl do the same. Previous
517 behavior was wrong.
518

887 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001270- Issue #7301: Add environment variable $PYTHONWARNINGS.
1271
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001272- Issue #8329: Don't return the same lists from select.select when no fds are
1273 changed.
1274
Georg Brandlfee0f442010-05-22 21:26:21 +00001275- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001276 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00001285- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1286 with a non-empty format string. This is an effort to future-proof user
1287 code. If a derived class does not currently implement __format__ but later
1288 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001289 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001290 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001323- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001340- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1341 InvalidOperation instead of returning False. (Comparisons involving a quiet
1342 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1343 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001344
Georg Brandlfee0f442010-05-22 21:26:21 +00001345- Issue #2531: Comparison operations between floats and Decimal instances now
1346 return a result based on the numeric values of the operands; previously they
1347 returned an arbitrary result based on the relative ordering of id(float) and
1348 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001351 argument `-` which tells it to read files to compile from stdin. Each line is
1352 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001362- Comparisons using one of <, <=, >, >= between a complex instance and a
1363 Fractions instance now raise TypeError instead of returning True/False. This
1364 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1365 <=> complex, and complex <=> complex comparisons.

1707 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001708 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00001722- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1723 and add the additional members returned in an OSVERSIONINFOEX structure. The
1724 new members are service_pack_major, service_pack_minor, suite_mask, and
1725 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00001727- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1728 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1729 returning NULL. The macro now returns a statically allocated empty string
1730 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00001731

1740 strings,
1741 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1742 numeric strings corresponding to subnormal values,
1743 (3) a memory leak for some values large enough to cause overflow, and
1744 (4) a number of flaws that could lead to incorrectly rounded results.

1762 interpreter shutdown.
1763
Georg Brandlba83f822010-03-14 09:50:54 +00001764- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00001775- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001776 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001777 Also, raise ValueError rather than TypeError when an unknown TIPC address
1778 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001782- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001783 file position when calling `truncate()`. It would previously change the file
1784 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001785 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1786
Georg Brandlba83f822010-03-14 09:50:54 +00001787- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1788 class used to represent files stored inside an archive. The new
1789 implementation is significantly faster and can be wrapped in a
1790 ``io.BufferedReader`` object for more speedups. It also solves an issue
1791 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1792 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001801
Georg Brandlba83f822010-03-14 09:50:54 +00001802- Issue #7748: Since unicode values are supported for some metadata options in
1803 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1804 encoded string for them. This ensures that the upload and register commands
1805 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00001874What's New in Python 2.7 alpha 2?
1875=================================

1880-----------------
1881
Georg Brandlba83f822010-03-14 09:50:54 +00001882- The ``__complex__()`` method is now looked up on the class of instances to
1883 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001884
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001885- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1886 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1887
Mark Dickinson1b34d252010-01-01 17:27:30 +00001888- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001889 DeprecationWarning when passed a float argument where an integer was expected.
1890 These functions and methods now raise TypeError instead. The majority of the
1891 effects of this change are in the extension modules, but some core functions
1892 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1893 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001894

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001903- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1904 used to drop the time part of the result.
1905
Georg Brandlba83f822010-03-14 09:50:54 +00001906- Issue #1811: Improve accuracy and cross-platform consistency for true division
1907 of integers: the result of a/b is now correctly rounded for ints a and b (at
1908 least on IEEE 754 platforms), and in particular does not depend on the
1909 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001910
Georg Brandlba83f822010-03-14 09:50:54 +00001911- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1912 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1913 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001916 executables on OSX.
1917
Georg Brandlba83f822010-03-14 09:50:54 +00001918 These executables now work properly with the arch(1) command: ``arch -ppc
1919 python`` will start a universal binary version of python in PPC mode (unlike
1920 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001921
Georg Brandlba83f822010-03-14 09:50:54 +00001922- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1923 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00001942- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001943 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1944 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00001979- Issue #7349: Make methods of file objects in the io module accept None as an
1980 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1981 the same as passing no argument.
1982
Georg Brandlba83f822010-03-14 09:50:54 +00001983- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

2003 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +00002004
Georg Brandlba83f822010-03-14 09:50:54 +00002005- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2006 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2007 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2008 float arguments for integer format codes (other than 'L'): previously an

2060 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002061

Georg Brandlba83f822010-03-14 09:50:54 +00002076- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2077 decimal string that's guaranteed to round back to x under correct rounding
2078 (with round-half-to-even rounding mode). Previously it gave a string based on
2079 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2080 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2081 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002082
Georg Brandlba83f822010-03-14 09:50:54 +00002083- Issue #7117: On almost all platforms: float-to-string and string-to-float
2084 conversions within Python are now correctly rounded. Places these conversions
2085 occur include: str for floats and complex numbers; the float and complex
2086 constructors; old-style and new-style numeric formatting; serialization and
2087 deserialization of floats and complex numbers using marshal, pickle and json;
2088 parsing of float and imaginary literals in Python code; Decimal-to-float
2089 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002090
Georg Brandlba83f822010-03-14 09:50:54 +00002091 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2092 providing correctly-rounded strtod and dtoa C functions. This code is
2093 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2094 the C compiler. There may be a small number of platforms on which correct
2095 operation of this code cannot be guaranteed, so the code is not used: notably,
2096 this applies to platforms where the C double format is not IEEE 754 binary64,
2097 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2098 and Python's configure script is unable to determine how to change the FPU
2099 precision. On these platforms conversions use the platform strtod and dtoa,
2100 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002101
Georg Brandlba83f822010-03-14 09:50:54 +00002102- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2103 uses the correctly-rounded string <-> float conversions described above (when
2104 available), and so produces correctly rounded results that will display nicely
2105 under the float repr. There are two related small changes: (1) round now
2106 accepts any class with an ``__index__()`` method for its second argument (but
2107 no longer accepts floats for the second argument), and (2) an excessively
2108 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

2459
Georg Brandlba83f822010-03-14 09:50:54 +00002460- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2461 file objects with closefd=False. The file descriptor is still kept open but
2462 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002486- On windows, ``os.chdir()`` given unicode was not working if
2487 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2488 this code path is really executed because I cannot move to such directory on
2489 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002491- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2492 element is temporarily replaced with an equivalent frozenset. But the
2493 eventual KeyError would always report the empty ``frozenset()`` as the missing

2515 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2516 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00002519- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003892- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3893 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3894 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3895 ``printf`` function, whereas PyString_FromFormat has an independent
3896 implementation and uses "%zd" on all platforms for size_t values.
3897 This makes a difference on win64, where ``printf`` needs "%Id" to display
3898 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003918 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3919 mechanism. In the process, fix a bug where isinstance() and issubclass(),

3921 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3922 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003993 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3994 for catch_warnings() also led to an improvement in the raising of a
3995 DeprecationWarning related to warnings.warn_explicit().
3996

4019
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004020- Issue #2975: When compiling several extension modules with Visual Studio 2008
4021 from the same python interpreter, some environment variables would grow
4022 without limit.
4023
Benjamin Peterson37346b22008-08-23 20:27:43 +00004024- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4025 exploitation of poor argument checking.
4026
Gerhard Häringef2276b2008-09-12 13:54:06 +00004027- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004061What's New in Python 2.6 beta 3?
4062================================
4063
Barry Warsaw07a4a382008-08-21 01:15:08 +00004064*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004065
4066Core and Builtins
4067-----------------
4068
Guido van Rossumf8402962008-08-20 15:01:50 +00004069- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4070 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4071 extensions do not automatically benefit from the class attribute
4072 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4073 to their tp_flags field if they care. This is a backwards
4074 compatibility feature; in 3.0, all types will use the cache by
4075 default.
4076
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004077- Keyword arguments can now follow starred arguments. (``f(a, *args,
4078 keyword=23)`` is now valid syntax.)
4079
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004080- ctypes function pointers that are COM methods have a boolean True
4081 value again.
4082
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004083- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4084 by denying s# to parse objects that have a releasebuffer procedure,
4085 and introducing s*.
4086
Georg Brandl1e13ea92008-08-11 09:07:59 +00004087- Issue #3537: Fix an assertion failure when an empty but presized dict
4088 object was stored in the freelist.
4089
Mark Dickinsonb6467572008-08-04 21:30:09 +00004090- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4091 ValueError consistently across platforms.
4092
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004093- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4094 (64bit Unix, for example), unichr() would truncate its argument and return
4095 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4096
Neal Norwitze7d8be82008-07-31 17:17:14 +00004097- Apply security patches from Apple.
4098
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004099- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4100 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4101
Antoine Pitrou92f82162008-07-25 22:22:08 +00004102- Issue #1819: function calls with several named parameters are now on
4103 average 35% faster (as measured by pybench).
4104
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004105- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4106 the python debugger steps into a class statement: the free variables (local
4107 variables defined in an outer scope) would be deleted from the outer scope.
4108
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004109- Issue #2620: Overflow checking when allocating or reallocating memory
4110 was not always being done properly in some python types and extension
4111 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4112 all been updated to perform better checks and places in the code that
4113 would previously leak memory on the error path when such an allocation
4114 failed have been fixed.
4115
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004116Library
4117-------
4118

4120
Benjamin Petersone977ad42008-08-20 01:42:01 +00004121- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4122 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4123
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004124- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4125 version reported by these tools does not necessarily follow the python
4126 version numbering scheme, so the module is less strict when parsing it.
4127
Nick Coghlanf70385a2008-08-18 12:42:46 +00004128- Issue #2235: Added Py3k warnings for types which will become unhashable
4129 under the stricter __hash__ inheritance rules in 3.0. Several types
4130 which did not meet the rules for hash invariants and were already
4131 unhashable in 3.0 have now been explicitly flagged as unhashable in
4132 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4133 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4134
Brett Cannon88f801d2008-08-18 00:46:22 +00004135- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4143
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004144- Issue #3575: Incremental decoder's decode function now takes bytearray
4145 by using 's*' instead of 't#'.
4146
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004147- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004148 fails unicode conversion on 2nd parameter. (windows only)
4149
Georg Brandl222e2082010-08-01 22:27:39 +00004150- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004151 in a redirect.
4152
Brett Cannonabe423e2008-08-16 21:47:07 +00004153- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004154 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004155
Facundo Batistaeb90b782008-08-16 14:44:07 +00004156- Issue #2776: fixed small issue when handling an URL with double slash
4157 after a 302 response in the case of not going through a proxy.
4158
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004159- Issue #2676: in the email package, content-type parsing was hanging on
4160 pathological input because of quadratic or exponential behaviour of a
4161 regular expression.
4162
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004163- Issue #3476: binary buffered reading through the new "io" library is now
4164 thread-safe.
4165
Brett Cannonbf3157b2008-08-14 05:00:03 +00004166- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4167 since mimetools itself is deprecated. Because modules are cached, all
4168 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4169
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004170- Issue #3134: shutil referenced undefined WindowsError symbol.
4171
Robert Schuppenies14646332008-08-10 11:01:53 +00004172- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4173 menu entries were not deleted.
4174
Brett Cannon83e81842008-08-09 23:30:55 +00004175- Copied the implementation of reduce() to _functools.reduce() to have a
4176 version that did not raise a DeprecationWarning under -3.
4177
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004178- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4179 a MemoryError rather than silently stop the iteration.
4180
Guido van Rossum59ce9012008-08-09 14:55:34 +00004181- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4182 to _sre.compile() will now be rejected. This should not affect anybody
4183 since the re.compile() function never generates invalid re-bytecode.
4184
Skip Montanaroa032bf42008-08-08 22:52:51 +00004185- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4186 upon first access it can be automatically initialized from the csv file if
4187 it wasn't initialized during instantiation.
4188
Brett Cannon3aa2a492008-08-06 22:28:09 +00004189- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4190 the reload() built-in has been removed.
4191
Brett Cannon7e30b672008-08-04 21:52:25 +00004192- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004193 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004204 asking for a specific length. This problem only affected files opened
4205 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004206

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004260Core and Builtins
4261-----------------
4262
Georg Brandl3e483f62008-07-16 22:57:41 +00004263- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4264 its methods now allow for items objects that can be converted to
4265 an integer using operator.index().
4266
Mark Dickinson64b7e502008-07-16 09:40:03 +00004267- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4268 produced a ValueError instead of giving the correct float.
4269
Eric Smitha5fa5a22008-07-16 00:11:49 +00004270- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4271 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4272
Mark Dickinson7103aa42008-07-15 19:08:33 +00004273- Issue #3008: the float type has a new instance method 'float.hex'
4274 and a new class method 'float.fromhex' to convert floating-point
4275 numbers to and from hexadecimal strings, respectively.
4276
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004277- Issue #2235: __hash__ is once again inherited by default. To allow
4278 collections.Hashable to remain meaningful in the presence of the
4279 default hash implementation (object.__hash__), it is now possible
4280 to explicit block inheritance of hash by setting __hash__=None at
4281 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4282 level.
4283
Nick Coghlanb028f502008-07-13 14:52:36 +00004284- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4285 the parent module cannot be found while performing an absolute import.
4286 This means that an incorrectly defined __package__ attribute will
4287 now only prevent relative imports in that module rather than causing
4288 all imports from that module to fail.
4289
Nick Coghlan14ff9942008-07-08 14:21:42 +00004290- Issue #2517: Allow unicode messages in Exceptions again by correctly
4291 bypassing the instance dictionary when looking up __unicode__ on
4292 new-style classes.
4293
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004294- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4295 set to a custom object whose write() method happens to install
4296 another file in sys.stdout.
4297
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004298- Issue #3088: Corrected a race condition in classes derived from
4299 threading.local: the first member set by a thread could be saved in
4300 another thread's dictionary.
4301
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004302- Issue #3004: Minor change to slice.indices(): the start and stop
4303 arguments are now treated identically, making the behaviour easier
4304 to describe and understand. For example, slice(None, -10,
4305 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4306 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4307 10, -1).
4308
Georg Brandl278fc502008-07-19 12:46:12 +00004309- Issue #3219: Calling a function with repeated keyword arguments,
4310 f(a=2, a=23), would not cause a syntax error. This was a regression
4311 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004312
Georg Brandl278fc502008-07-19 12:46:12 +00004313- Issue #2862: Make int and float freelist management consistent with
4314 other freelists. Changes their CompactFreeList apis into
4315 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004316

4318-------
4319
Thomas Heller57adf222008-08-14 19:10:48 +00004320- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4321 api functions without holding the GIL, which could lead to a fatal
4322 error when they failed.
4323
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004324- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4325
Jesse Noller7fb96402008-07-17 21:01:05 +00004326- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

4331
Jesse Noller13e9d582008-07-16 14:32:36 +00004332- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4333 ForkingPickler.register() to resolve conflict with ctypes.
4334
Vinay Sajip51e65192008-07-18 09:01:10 +00004335- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004336
Thomas Heller880f5292008-07-15 19:39:38 +00004337- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4338 a valid dlerror() message.
4339
Thomas Heller2bad6572008-07-15 17:19:50 +00004340- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4341 incomplete structure was created.
4342
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004343- Issue #3339: dummy_thread.acquire() should not return None.
4344
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004345- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4346
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004347- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004348
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004349- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4350 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004351 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004352 content-length. The problem had been corrected in the 2.4 branch, but never
4353 merged into trunk.
4354
Georg Brandle78fbcc2008-07-05 10:13:36 +00004355- Issue #2663: add filtering capability to shutil.copytree().

4358
4359- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4360
4361- Issue #1746: Correct handling of zipfile archive comments (previously
4362 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004363 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004364
Vinay Sajip51e65192008-07-18 09:01:10 +00004365- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004366 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004367
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004368- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4369 handling is now the same as that of other special attributes like __name__).
4370
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004371- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4372 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004823- Issue #1631171: Re-implement the 'warnings' module in C (the
4824 original Python code has been kept as backup). This will allow for
4825 using the 'warning's machinery in such places as the parser where
4826 use of pure Python code is not possible. Both the ``showarning()``
4827 and ``formatwarning()`` gain an optional 'line' argument which is
4828 not called by default for backwards-compatibility reasons. Setting
4829 ``warnings.showwarning()`` to an implementation that lacks support
4830 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Issue #2550: The approach used by client/server code for obtaining
4894 ports to listen on in network-oriented tests has been refined in an
4895 effort to facilitate running multiple instances of the entire
4896 regression test suite in parallel without issue.
4897 test_support.bind_port() has been fixed such that it will always
4898 return a unique port -- which wasn't always the case with the
4899 previous implementation, especially if socket options had been set
4900 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4901 new implementation of bind_port() will actually raise an exception
4902 if it is passed an AF_INET/SOCK_STREAM socket with either the
4903 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4904 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4905 the socket it's been passed. This currently only applies to
4906 Windows. This option prevents any other sockets from binding to the
4907 host/port we've bound to, thus removing the possibility of the
4908 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4909 when a second SOCK_STREAM socket binds and accepts to a host/port
4910 that's already been bound by another socket. The optional preferred
4911 port parameter to bind_port() has been removed. Under no
4912 circumstances should tests be hard coding ports!
4913
4914 test_support.find_unused_port() has also been introduced, which will
4915 pass a temporary socket object to bind_port() in order to obtain an
4916 unused port. The temporary socket object is then closed and
4917 deleted, and the port is returned. This method should only be used
4918 for obtaining an unused port in order to pass to an external program
4919 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4920 a parameter to a server-oriented class that doesn't give you direct
4921 access to the underlying socket used.
4922
4923 Finally, test_support.HOST has been introduced, which should be used
4924 for the host argument of any relevant socket calls (i.e. bind and
4925 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004926
4927 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004929 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4930 test_asynchat and test_socket_ssl.
4931
Georg Brandl3ee81df2008-05-17 18:14:43 +00004932 It is now possible for multiple instances of the regression test
4933 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005212- Added the future_builtins module, which contains hex() and oct().
5213 These are the PEP 3127 version of these functions, designed to be
5214 compatible with the hex() and oct() builtins from Python 3.0. They
5215 differ slightly in their output formats from the existing, unchanged
5216 Python 2.6 builtins. The expected usage of the future_builtins
5217 module is:
5218 from future_builtins import hex, oct
5219
Eric Smith7ef40bf2008-02-20 23:34:22 +00005220- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5221 exponents for exponents with absolute value < 100. Follows C99
5222 standard. This is a change on Windows, which would use 3 digits.
5223 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5224 so that any alterations it does to the resulting string will be
5225 available in stringlib/formatter.h (for float.__format__).
5226
Eric Smith5a3c1352008-02-19 13:21:56 +00005227- Implemented PEP 3101, Advanced String Formatting. This adds a new
5228 builtin format(); a format() method for str and unicode; a
5229 __format__() method to object, str, unicode, int, long, float, and
5230 datetime; the class string.Formatter; and the C API
5231 PyObject_Format().
5232
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- Fixed several potential crashes, all caused by specially crafted
5234 __del__ methods exploiting objects in temporarily inconsistent
5235 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005236
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005237- Issue #2115: Important speedup in setting __slot__ attributes. Also

Georg Brandl3ee81df2008-05-17 18:14:43 +00005244- Clear all free lists during a gc.collect() of the highest generation
5245 in order to allow pymalloc to free more arenas. Python may give back
5246 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005247
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248- Issue #2045: Fix an infinite recursion triggered when printing a
5249 subclass of collections.defaultdict, if its default_factory is set
5250 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005251
Christian Heimesf75dbef2008-02-08 00:11:31 +00005252- Fixed a minor memory leak in dictobject.c. The content of the free
5253 list was not freed on interpreter shutdown.
5254
Georg Brandl21e99f42010-03-07 15:23:59 +00005255- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005257
Georg Brandl3ee81df2008-05-17 18:14:43 +00005258- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5259 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005260 to compact the internal free lists of pre-allocted ints and floats.
5261
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5263 calls. Python expected the return type int but the fork familie
5264 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005265

Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Patch #1473257: generator objects gain a gi_code attribute. This is
5279 the same object as the func_code attribute of the function that
5280 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005281
Georg Brandl3ee81df2008-05-17 18:14:43 +00005282- Issue #1920: "while 0" statements were completely removed by the
5283 compiler, even in the presence of an "else" clause, which is
5284 supposed to be run when the condition is false. Now the compiler
5285 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005286
Guido van Rossumeead05f2008-01-24 18:21:02 +00005287- A few crashers fixed: weakref_in_del.py (issue #1377858);
5288 loosing_dict_ref.py (issue #1303614, test67.py);
5289 borrowed_ref_[34].py (not in tracker).
5290

5294
Georg Brandl3ee81df2008-05-17 18:14:43 +00005295- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005296 several extension methods and modules do not work without unicode
5297 support.
5298
Georg Brandl26543b12008-01-21 18:36:51 +00005299- Issue #1882: when compiling code from a string, encoding cookies in the

5301
Georg Brandl14404b62008-01-19 19:27:05 +00005302- Issue #1679: "0x" was taken as a valid integer literal.
5303
Georg Brandl6caad7d2008-01-26 14:19:22 +00005304- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005305 added.
5306
Christian Heimesc94e2b52008-01-14 04:13:37 +00005307- sys.float_info / PyFloat_GetInfo: The floating point information
5308 object was converted from a dict to a specialized structseq object.
5309
Georg Brandl3ee81df2008-05-17 18:14:43 +00005310- Patch #1816: Added sys.flags structseq. It exposes the status of
5311 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005329- Improve some exception messages when Windows fails to load an
5330 extension module. Now we get for example '%1 is not a valid Win32
5331 application' instead of 'error code 193'.

5344 dictionary size. There is a new opcode, STORE_MAP, for adding
5345 entries to the dictionary.

5375 file can now be directly executed by passing their name to the
5376 interpreter. The directory/zipfile is automatically inserted as the
5377 first entry in sys.path.

5388
Georg Brandl21e99f42010-03-07 15:23:59 +00005389- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005390 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5391 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005392
Georg Brandl3ee81df2008-05-17 18:14:43 +00005393- Issue #1686386: Tuple's tp_repr did not take into account the
5394 possibility of having a self-referential tuple, which is possible
5395 from C code. Nor did object's tp_str consider that a type's tp_str
5396 could do something that could lead to an inifinite recursion.
5397 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5398 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005399
Georg Brandl3ee81df2008-05-17 18:14:43 +00005400- Issue #1164: It was possible to trigger deadlock when using the
5401 'print' statement to write to a file since the GIL was not released
5402 as needed. Now PyObject_Print() does the right thing along with
5403 various tp_print implementations of the built-in types and those in
5404 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00005413- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414 PyObject_Call() never calling back out to Python code to trigger
5415 recursion depth updates/checks. Required the creation of a static
5416 RuntimeError instance in case normalizing an exception put the
5417 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00005434 __*__ attributes. (Some already existed, e.g., __doc__ and
5435 __name__.)

5441 calls.
5442
Collin Winter62903052007-05-18 23:11:24 +00005443- except clauses may now be spelled either "except E, target:" or

5445 with Python 3.0.

5454
Raymond Hettinger13936692007-04-11 18:40:58 +00005455- Request #1191699: Slices can now be pickled.

5459 remaining characters.
5460
Georg Brandl5cb76c12007-03-21 09:00:39 +00005461- Patch #1682205: a TypeError while unpacking an iterable is no longer

5465
Guido van Rossum143b5642007-03-23 04:58:42 +00005466- Bug #1683368: The object.__init__() and object.__new__() methods are
5467 now stricter in rejecting excess arguments. The only time when
5468 either allows excess arguments is when it is not overridden and the
5469 other one is. For backwards compatibility, when both are
5470 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005471 warning later). Also, type.__init__() insists on the same signature
5472 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5475 object to complex using its __complex__() method before falling back
5476 to the __float__() method. Therefore, the functions in the cmath
5477 module now can operate on objects that define a __complex__()
5478 method.

5495
Georg Brandl7b9c5552007-03-12 14:30:05 +00005496- Bug #1678647: write a newline after printing an exception in any
5497 case, even when converting the value to a string failed.
5498
Georg Brandl871f1bc2007-03-12 13:17:36 +00005499- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005500 its argument, if it exists. If not, it will work like before. This
5501 allows customizing the output of dir() in the presence of a
5502 __getattr__().

5512 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005513
Georg Brandlaa2321b2007-03-07 00:40:28 +00005514- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005515 makes the filenames the warning module prints much more sensible
5516 when a PYTHONSTARTUP file is used.

5530 sq_ass_slice instead of the sq_slice slot.
5531
Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006102 are set for invalid interpolation sequences that would lead to

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006450 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006452 does not claim to support starttls. Adds the
6453 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006552 time so that opening a database previously created with the DB_DUP
6553 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6554 opens. Specifically: dictionary assignment to a DB object will
6555 replace all values for a given key when the database allows
6556 duplicate values. DB users should use DB.put(k, v) when they want
6557 to store duplicates; not DB[k] = v.

6913 of w# format code incorrectly truncated the length to an int, even
6914 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6915 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006941- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6942 absolute imports. In earlier versions they might have used relative
6943 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006944
Georg Brandl3ee81df2008-05-17 18:14:43 +00006945- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6946 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006947
