Ned Deily18fae3f2013-01-31 01:24:55 -0800754- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
755 In particular, fix extension module build failures when trying to use
756 32-bit-only installer Pythons on systems with Xcode 4 (currently
757 OS X 10.8, 10.7, and optionally 10.6).
758 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
759 * Since Xcode 4 removes ppc support, extension module builds now
760 check for ppc compiler support and by default remove ppc and
761 ppc64 archs when they are not available.
762 * Extension module builds now revert to using system installed
763 headers and libs (/usr and /System/Library) if the SDK used
764 to build the interpreter is not installed or has moved.
765 * Try to avoid building extension modules with deprecated
766 and problematic Apple llvm-gcc compiler. If original compiler
767 is not available, use clang instead by default.

1014 incorrect results with recent versions of Clang, as a result of the

1016 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001086 has left two versions of customize_compiler, the original in
1087 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001092- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1093 Distutils-based packages with C extension modules may fail because
1094 Apple has removed gcc-4.2, the version used to build python.org
1095 64-bit/32-bit Pythons. If the user does not explicitly override
1096 the default C compiler by setting the CC environment variable,
1097 Distutils will now attempt to compile extension modules with clang
1098 if gcc-4.2 is required but not found. Also as a convenience, if
1099 the user does explicitly set CC, substitute its value as the default
1100 compiler in the Distutils LDSHARED configuration variable for OS X.
1101 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1102 SDK, neither of which are available in Xcode 4. This change does not
1103 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001376- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1377 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1378 interpreter process. This could cause failures in non-Distutils subprocesses
1379 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001380 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001381 deployment target only in the environment of each build subprocess. It is
1382 still possible to globally override the default by setting
1383 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1384 greater or equal to the default value, the value with which the interpreter
1385 was built.

1415 the ticker doesn't have to wind down to zero from the old starting point
1416 before the new interval takes effect. And if the user increases the
1417 interval, it makes sure the new limit takes effect right away rather have an
1418 early task switch before recognizing the new interval.

2337 with invalid characters after '=' in a Q-encoded word.
2338
Antoine Pitrou66b5df62010-09-27 18:16:46 +00002339- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
2340 received. Now sendall() properly calls signal handlers if necessary,

2353 handles non-blocking readinto() returning None correctly.

2359 by Andrew Bennetts.
2360

2368
Raymond Hettinger20397532010-09-12 02:11:45 +00002369- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2370 This prevents user-created self-referencing ordered dictionaries from
2371 becoming permanently uncollectable GC garbage. The downside is that
2372 removing __del__ means that the internal doubly-linked list has to wait for
2373 GC collection rather than freeing memory immediately when the refcnt drops
2374 to zero.
2375
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002376- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002377 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002378 value.
2379
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002380- Issue #9792: In case of connection failure, socket.create_connection()
2381 would swallow the exception and raise a new one, making it impossible
2382 to fetch the original errno, or to filter timeout errors. Now the
2383 original error is re-raised.
2384
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002385- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2386 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2387 be updated back after the system call. Original patch by Brian Brazil.
2388
Antoine Pitroudca9de92010-09-04 17:52:26 +00002389- Issue #1100562: Fix deep-copying of objects derived from the list and

2393 ConfigParser.write.
2394
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002395- Issue #808164: Fixed socket.close to avoid references to globals, to
2396 avoid issues when socket.close is called from a __del__ method.
2397
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002398- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2399 can be set to False to turn off the previously undocumented 'popularity'
2400 heuristic. Patch by Terry Reedy and Eli Bendersky
2401
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002402- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2403 falling into recursion.
2404
R. David Murray7c4bf552010-08-25 01:45:57 +00002405- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2406 character years even if the message contains RFC822 two character years.
2407
Daniel Stutzbach91287322010-08-24 21:09:30 +00002408- Issue #8750: Fixed MutableSet's methods to correctly handle

2420 module now correctly return a set. (Patch by Eli Bendersky.)
2421
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002422- Issue #9617: Signals received during a low-level write operation aren't
2423 ignored by the buffered IO layer anymore.
2424
Benjamin Peterson52c36052010-08-21 03:03:22 +00002425- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2426 are not held onto after they are deleted elsewhere.
2427
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002428- Issue #9626: the view methods for collections.OrderedDict() were returning

2439
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002440- Issue #9550: a BufferedReader could issue an additional read when the
2441 original read request had been satisfied, which could block indefinitely
2442 when the underlying raw IO channel was e.g. a socket. Report and original
2443 patch by Jason V. Miller.
2444
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002445- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002463- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2464 This is how it is supposed to work, wget and curl do the same. Previous
2465 behavior was wrong.

2473 the option character for the added 'h/help' option if prefix_chars
2474 does not contain a '-', instead of raising an error.
2475

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003194 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

3217-----------------
3218
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003219- Issue #7301: Add environment variable $PYTHONWARNINGS.
3220
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003221- Issue #8329: Don't return the same lists from select.select when no fds are
3222 changed.
3223
Georg Brandlfee0f442010-05-22 21:26:21 +00003224- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003225 on 64-bit machines. The shift count for either left or right shift is
3226 permitted to be up to sys.maxsize.
3227
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003228- Ensure that tokenization of identifiers is not affected by locale.
3229
Georg Brandlfee0f442010-05-22 21:26:21 +00003230- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003231
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003232- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3233
Georg Brandlfee0f442010-05-22 21:26:21 +00003234- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3235 with a non-empty format string. This is an effort to future-proof user
3236 code. If a derived class does not currently implement __format__ but later
3237 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003238 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003239 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003240
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003241- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003254- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003255 (SIGINT). If an error occurs while importing the site module, the error is

3271
Georg Brandlfee0f442010-05-22 21:26:21 +00003272- Issue #8257: The Decimal construct now accepts a float instance directly,
3273 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003274
3275 >>> Decimal(1.1)
3276 Decimal('1.100000000000000088817841970012523233890533447265625')
3277
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003278- collections.Counter() now supports a subtract() method.
3279
Georg Brandlfee0f442010-05-22 21:26:21 +00003280- The functools module now has a total_ordering() class decorator to simplify
3281 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003289- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3290 InvalidOperation instead of returning False. (Comparisons involving a quiet
3291 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3292 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003293
Georg Brandlfee0f442010-05-22 21:26:21 +00003294- Issue #2531: Comparison operations between floats and Decimal instances now
3295 return a result based on the numeric values of the operands; previously they
3296 returned an arbitrary result based on the relative ordering of id(float) and
3297 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003298
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003299- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003300 argument `-` which tells it to read files to compile from stdin. Each line is
3301 read on demand and the named file is compiled immediately. (Original patch by
3302 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003307- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3308 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003309 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003310
Georg Brandlfee0f442010-05-22 21:26:21 +00003311- Comparisons using one of <, <=, >, >= between a complex instance and a
3312 Fractions instance now raise TypeError instead of returning True/False. This
3313 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3314 <=> complex, and complex <=> complex comparisons.

3414 integer format code, struct.pack first attempts to convert the non-integer

3419 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3420 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003421 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3422 inconsistent: __int__ was used for some integer codes but not for others, and
3423 the set of integer codes for which it was used differed between native packing
3424 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003732 file position when calling `truncate()`. It would previously change the file
3733 position to the given argument, which goes against the tradition of

3737 class used to represent files stored inside an archive. The new
3738 implementation is significantly faster and can be wrapped in a

3740 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3753 encoded string for them. This ensures that the upload and register commands
3754 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004025- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4026 decimal string that's guaranteed to round back to x under correct rounding
4027 (with round-half-to-even rounding mode). Previously it gave a string based on
4028 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4029 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4030 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004031
Georg Brandlba83f822010-03-14 09:50:54 +00004032- Issue #7117: On almost all platforms: float-to-string and string-to-float
4033 conversions within Python are now correctly rounded. Places these conversions
4034 occur include: str for floats and complex numbers; the float and complex
4035 constructors; old-style and new-style numeric formatting; serialization and
4036 deserialization of floats and complex numbers using marshal, pickle and json;
4037 parsing of float and imaginary literals in Python code; Decimal-to-float
4038 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004039
Georg Brandlba83f822010-03-14 09:50:54 +00004040 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4041 providing correctly-rounded strtod and dtoa C functions. This code is
4042 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4043 the C compiler. There may be a small number of platforms on which correct
4044 operation of this code cannot be guaranteed, so the code is not used: notably,
4045 this applies to platforms where the C double format is not IEEE 754 binary64,
4046 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4047 and Python's configure script is unable to determine how to change the FPU
4048 precision. On these platforms conversions use the platform strtod and dtoa,
4049 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004051- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4052 uses the correctly-rounded string <-> float conversions described above (when
4053 available), and so produces correctly rounded results that will display nicely
4054 under the float repr. There are two related small changes: (1) round now
4055 accepts any class with an ``__index__()`` method for its second argument (but
4056 no longer accepts floats for the second argument), and (2) an excessively
4057 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4058 raises an exception.

4208 of 12. Previously, the behavior the same but with a default precision of 6.
4209 This more closely matches ``str()``, and reduces surprises when adding

4323
Benjamin Peterson596d3062009-01-19 15:42:23 +00004324- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00004351- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4352 existing .py counterpart, override the co_filename attributes of all code
4353 objects if the original filename is obsolete (which can happen if the file has

4408
Georg Brandlba83f822010-03-14 09:50:54 +00004409- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4410 file objects with closefd=False. The file descriptor is still kept open but
4411 the file object behaves like a closed file. The ``FileIO`` object also got a
4412 new readonly attribute ``closefd``.

4431
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004432- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004435- On windows, ``os.chdir()`` given unicode was not working if
4436 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4437 this code path is really executed because I cannot move to such directory on
4438 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004440- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4441 element is temporarily replaced with an equivalent frozenset. But the
4442 eventual KeyError would always report the empty ``frozenset()`` as the missing
4443 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004463- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4464 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4465 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4466 of using the replace error handler in PyUnicode_DecodeUTF8().
4467
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004468- Issue #3739: The unicode-internal encoder now reports the number of characters

4470
Georg Brandlba83f822010-03-14 09:50:54 +00004471- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4472 allocator will be automatically disabled when running under Valgrind. This
4473 gives improved memory leak detection when running under Valgrind, while taking
4474 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00004546 __main__.py file. This allows applications that run other Python scripts to
4547 support the same flexibility as the CPython command line itself.

5840
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005841- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5842 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5843 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5844 ``printf`` function, whereas PyString_FromFormat has an independent
5845 implementation and uses "%zd" on all platforms for size_t values.
5846 This makes a difference on win64, where ``printf`` needs "%Id" to display
5847 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005849- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5853 object; previously an int would be returned for small values. the __long__

5865
Vinay Sajip35e3b032008-09-01 14:33:59 +00005866- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005867 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5868 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5869 when given a tuple of classes as second argument, were looking up
5870 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5871 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005942 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5943 for catch_warnings() also led to an improvement in the raising of a
5944 DeprecationWarning related to warnings.warn_explicit().
5945
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005946- The deprecation warnings for the old camelCase threading API were removed.

5968
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005969- Issue #2975: When compiling several extension modules with Visual Studio 2008
5970 from the same python interpreter, some environment variables would grow
5971 without limit.
5972
Benjamin Peterson37346b22008-08-23 20:27:43 +00005973- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5974 exploitation of poor argument checking.
5975
Gerhard Häringef2276b2008-09-12 13:54:06 +00005976- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

5989 wrapper for warnings.catch_warnings() that makes it easier to check
5990 that expected warning messages are being reported.
5991

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006010What's New in Python 2.6 beta 3?
6011================================
6012
Barry Warsaw07a4a382008-08-21 01:15:08 +00006013*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006014
6015Core and Builtins
6016-----------------
6017
Guido van Rossumf8402962008-08-20 15:01:50 +00006018- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6019 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6020 extensions do not automatically benefit from the class attribute
6021 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6022 to their tp_flags field if they care. This is a backwards
6023 compatibility feature; in 3.0, all types will use the cache by
6024 default.
6025
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006026- Keyword arguments can now follow starred arguments. (``f(a, *args,
6027 keyword=23)`` is now valid syntax.)
6028
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006029- ctypes function pointers that are COM methods have a boolean True
6030 value again.
6031
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006032- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6033 by denying s# to parse objects that have a releasebuffer procedure,
6034 and introducing s*.
6035
Georg Brandl1e13ea92008-08-11 09:07:59 +00006036- Issue #3537: Fix an assertion failure when an empty but presized dict
6037 object was stored in the freelist.
6038
Mark Dickinsonb6467572008-08-04 21:30:09 +00006039- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6040 ValueError consistently across platforms.
6041
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006042- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6043 (64bit Unix, for example), unichr() would truncate its argument and return
6044 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6045
Neal Norwitze7d8be82008-07-31 17:17:14 +00006046- Apply security patches from Apple.
6047
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006048- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6049 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6050
Antoine Pitrou92f82162008-07-25 22:22:08 +00006051- Issue #1819: function calls with several named parameters are now on
6052 average 35% faster (as measured by pybench).
6053
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006054- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6055 the python debugger steps into a class statement: the free variables (local
6056 variables defined in an outer scope) would be deleted from the outer scope.
6057
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006058- Issue #2620: Overflow checking when allocating or reallocating memory
6059 was not always being done properly in some python types and extension
6060 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6061 all been updated to perform better checks and places in the code that
6062 would previously leak memory on the error path when such an allocation
6063 failed have been fixed.
6064

6066-------
6067
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006068- Issue #3612: Added some missing basic types in ctypes.wintypes.
6069
Benjamin Petersone977ad42008-08-20 01:42:01 +00006070- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6071 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6072
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006073- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6074 version reported by these tools does not necessarily follow the python
6075 version numbering scheme, so the module is less strict when parsing it.
6076
Nick Coghlanf70385a2008-08-18 12:42:46 +00006077- Issue #2235: Added Py3k warnings for types which will become unhashable
6078 under the stricter __hash__ inheritance rules in 3.0. Several types
6079 which did not meet the rules for hash invariants and were already
6080 unhashable in 3.0 have now been explicitly flagged as unhashable in
6081 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6082 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6083
Brett Cannon88f801d2008-08-18 00:46:22 +00006084- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6085 imported into the module but exposed as part of the module's API.
6086
Brett Cannon7b96f072008-08-18 00:41:11 +00006087- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6088
Brett Cannon46225e72008-08-18 00:36:52 +00006089- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006091- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6092
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006093- Issue #3575: Incremental decoder's decode function now takes bytearray
6094 by using 's*' instead of 't#'.
6095
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006096- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006097 fails unicode conversion on 2nd parameter. (windows only)
6098
Georg Brandl222e2082010-08-01 22:27:39 +00006099- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006100 in a redirect.
6101
Brett Cannonabe423e2008-08-16 21:47:07 +00006102- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006103 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006104
Facundo Batistaeb90b782008-08-16 14:44:07 +00006105- Issue #2776: fixed small issue when handling an URL with double slash
6106 after a 302 response in the case of not going through a proxy.
6107
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006108- Issue #2676: in the email package, content-type parsing was hanging on
6109 pathological input because of quadratic or exponential behaviour of a
6110 regular expression.
6111
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006112- Issue #3476: binary buffered reading through the new "io" library is now
6113 thread-safe.
6114
Brett Cannonbf3157b2008-08-14 05:00:03 +00006115- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6116 since mimetools itself is deprecated. Because modules are cached, all
6117 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6118
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006119- Issue #3134: shutil referenced undefined WindowsError symbol.
6120
Robert Schuppenies14646332008-08-10 11:01:53 +00006121- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6122 menu entries were not deleted.
6123
Brett Cannon83e81842008-08-09 23:30:55 +00006124- Copied the implementation of reduce() to _functools.reduce() to have a
6125 version that did not raise a DeprecationWarning under -3.
6126
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006127- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6128 a MemoryError rather than silently stop the iteration.
6129
Guido van Rossum59ce9012008-08-09 14:55:34 +00006130- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6131 to _sre.compile() will now be rejected. This should not affect anybody
6132 since the re.compile() function never generates invalid re-bytecode.
6133
Skip Montanaroa032bf42008-08-08 22:52:51 +00006134- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6135 upon first access it can be automatically initialized from the csv file if
6136 it wasn't initialized during instantiation.
6137
Brett Cannon3aa2a492008-08-06 22:28:09 +00006138- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6139 the reload() built-in has been removed.
6140
Brett Cannon7e30b672008-08-04 21:52:25 +00006141- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006142 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006153 asking for a specific length. This problem only affected files opened
6154 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006155

6180 file name rather than a ZipInfo instance, so files are extracted with
6181 mode 0600 rather than 000 under Unix.
6182
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006183- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6184 argument in python 2.5, this broke code that subclassed Popen to include its
6185 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6200 regarding lack of coverage of new-style classes have also been
6201 removed, since the coverage is now fairly reasonable.

6211
Georg Brandl3e483f62008-07-16 22:57:41 +00006212- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6213 its methods now allow for items objects that can be converted to
6214 an integer using operator.index().
6215
Mark Dickinson64b7e502008-07-16 09:40:03 +00006216- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6217 produced a ValueError instead of giving the correct float.
6218
Eric Smitha5fa5a22008-07-16 00:11:49 +00006219- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6220 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6221
Mark Dickinson7103aa42008-07-15 19:08:33 +00006222- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00006226- Issue #2235: __hash__ is once again inherited by default. To allow
6227 collections.Hashable to remain meaningful in the presence of the
6228 default hash implementation (object.__hash__), it is now possible
6229 to explicit block inheritance of hash by setting __hash__=None at
6230 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6231 level.
6232
Nick Coghlanb028f502008-07-13 14:52:36 +00006233- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6234 the parent module cannot be found while performing an absolute import.
6235 This means that an incorrectly defined __package__ attribute will
6236 now only prevent relative imports in that module rather than causing
6237 all imports from that module to fail.
6238
Nick Coghlan14ff9942008-07-08 14:21:42 +00006239- Issue #2517: Allow unicode messages in Exceptions again by correctly

6250
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006251- Issue #3004: Minor change to slice.indices(): the start and stop
6252 arguments are now treated identically, making the behaviour easier
6253 to describe and understand. For example, slice(None, -10,
6254 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6255 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6256 10, -1).

6299 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006300 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00006710 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006711
6712 This is controlled by the configure argument ``--with-universal-archs``:
6713

6715
6716 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6717
6718 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

6759 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006760
Christian Heimese74c8f22008-04-19 02:23:57 +00006761- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006772- Issue #1631171: Re-implement the 'warnings' module in C (the
6773 original Python code has been kept as backup). This will allow for
6774 using the 'warning's machinery in such places as the parser where
6775 use of pure Python code is not possible. Both the ``showarning()``
6776 and ``formatwarning()`` gain an optional 'line' argument which is
6777 not called by default for backwards-compatibility reasons. Setting
6778 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Issue #2550: The approach used by client/server code for obtaining
6843 ports to listen on in network-oriented tests has been refined in an
6844 effort to facilitate running multiple instances of the entire
6845 regression test suite in parallel without issue.
6846 test_support.bind_port() has been fixed such that it will always
6847 return a unique port -- which wasn't always the case with the
6848 previous implementation, especially if socket options had been set
6849 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6850 new implementation of bind_port() will actually raise an exception
6851 if it is passed an AF_INET/SOCK_STREAM socket with either the
6852 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6853 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6854 the socket it's been passed. This currently only applies to
6855 Windows. This option prevents any other sockets from binding to the
6856 host/port we've bound to, thus removing the possibility of the
6857 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6858 when a second SOCK_STREAM socket binds and accepts to a host/port
6859 that's already been bound by another socket. The optional preferred
6860 port parameter to bind_port() has been removed. Under no
6861 circumstances should tests be hard coding ports!
6862
6863 test_support.find_unused_port() has also been introduced, which will
6864 pass a temporary socket object to bind_port() in order to obtain an
6865 unused port. The temporary socket object is then closed and
6866 deleted, and the port is returned. This method should only be used
6867 for obtaining an unused port in order to pass to an external program
6868 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6869 a parameter to a server-oriented class that doesn't give you direct
6870 access to the underlying socket used.
6871
6872 Finally, test_support.HOST has been introduced, which should be used
6873 for the host argument of any relevant socket calls (i.e. bind and
6874 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006875
6876 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006877 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006878 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6879 test_asynchat and test_socket_ssl.
6880
Georg Brandl3ee81df2008-05-17 18:14:43 +00006881 It is now possible for multiple instances of the regression test
6882 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007048- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
7049 values on 32-bit vs. 64-bit python interpreters. Both were correct,
7050 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00007161- Added the future_builtins module, which contains hex() and oct().
7162 These are the PEP 3127 version of these functions, designed to be
7163 compatible with the hex() and oct() builtins from Python 3.0. They
7164 differ slightly in their output formats from the existing, unchanged
7165 Python 2.6 builtins. The expected usage of the future_builtins
7166 module is:
7167 from future_builtins import hex, oct
7168
Eric Smith7ef40bf2008-02-20 23:34:22 +00007169- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7170 exponents for exponents with absolute value < 100. Follows C99
7171 standard. This is a change on Windows, which would use 3 digits.
7172 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7173 so that any alterations it does to the resulting string will be
7174 available in stringlib/formatter.h (for float.__format__).
7175
Eric Smith5a3c1352008-02-19 13:21:56 +00007176- Implemented PEP 3101, Advanced String Formatting. This adds a new
7177 builtin format(); a format() method for str and unicode; a
7178 __format__() method to object, str, unicode, int, long, float, and
7179 datetime; the class string.Formatter; and the C API
7180 PyObject_Format().
7181
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182- Fixed several potential crashes, all caused by specially crafted
7183 __del__ methods exploiting objects in temporarily inconsistent
7184 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007185
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007186- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187 prevent a possible crash: an Abstract Base Class would try to access
7188 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007189
Georg Brandl3ee81df2008-05-17 18:14:43 +00007190- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00007193- Clear all free lists during a gc.collect() of the highest generation
7194 in order to allow pymalloc to free more arenas. Python may give back
7195 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Issue #2045: Fix an infinite recursion triggered when printing a
7198 subclass of collections.defaultdict, if its default_factory is set
7199 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007200
Christian Heimesf75dbef2008-02-08 00:11:31 +00007201- Fixed a minor memory leak in dictobject.c. The content of the free
7202 list was not freed on interpreter shutdown.
7203
Georg Brandl21e99f42010-03-07 15:23:59 +00007204- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007206
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7208 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007209 to compact the internal free lists of pre-allocted ints and floats.
7210
Georg Brandl3ee81df2008-05-17 18:14:43 +00007211- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7212 calls. Python expected the return type int but the fork familie
7213 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007214
Georg Brandl3ee81df2008-05-17 18:14:43 +00007215- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7216 appear in the same code unit.

7225 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007226
Georg Brandl3ee81df2008-05-17 18:14:43 +00007227- Patch #1473257: generator objects gain a gi_code attribute. This is
7228 the same object as the func_code attribute of the function that
7229 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007230
Georg Brandl3ee81df2008-05-17 18:14:43 +00007231- Issue #1920: "while 0" statements were completely removed by the
7232 compiler, even in the presence of an "else" clause, which is
7233 supposed to be run when the condition is false. Now the compiler
7234 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007235
Guido van Rossumeead05f2008-01-24 18:21:02 +00007236- A few crashers fixed: weakref_in_del.py (issue #1377858);
7237 loosing_dict_ref.py (issue #1303614, test67.py);
7238 borrowed_ref_[34].py (not in tracker).
7239
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007240- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007241 suppressed while an extension is loaded by calling SetErrorMode in
7242 dynload_win.c. The error is still reported properly.
7243
Georg Brandl3ee81df2008-05-17 18:14:43 +00007244- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007245 several extension methods and modules do not work without unicode
7246 support.
7247
Georg Brandl26543b12008-01-21 18:36:51 +00007248- Issue #1882: when compiling code from a string, encoding cookies in the
7249 second line of code were not always recognized correctly.
7250
Georg Brandl14404b62008-01-19 19:27:05 +00007251- Issue #1679: "0x" was taken as a valid integer literal.
7252
Georg Brandl6caad7d2008-01-26 14:19:22 +00007253- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007254 added.
7255
Christian Heimesc94e2b52008-01-14 04:13:37 +00007256- sys.float_info / PyFloat_GetInfo: The floating point information
7257 object was converted from a dict to a specialized structseq object.
7258
Georg Brandl3ee81df2008-05-17 18:14:43 +00007259- Patch #1816: Added sys.flags structseq. It exposes the status of
7260 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007261
Georg Brandl3ee81df2008-05-17 18:14:43 +00007262- Objects/structseq.c: Implemented new structseq representation. The
7263 patch makes structseqs (e.g. the return value of os.stat) more
7264 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007265
Georg Brandl3ee81df2008-05-17 18:14:43 +00007266- Patch #1700288: added a type attribute cache that caches method

7275 envvar and sys.dont_write_bytecode attribute. All these can be set
7276 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007277
Georg Brandl3ee81df2008-05-17 18:14:43 +00007278- Improve some exception messages when Windows fails to load an
7279 extension module. Now we get for example '%1 is not a valid Win32
7280 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007281

Georg Brandl3ee81df2008-05-17 18:14:43 +00007291- Compiler now generates simpler and faster code for dictionary
7292 literals. The oparg for BUILD_MAP now indicates an estimated
7293 dictionary size. There is a new opcode, STORE_MAP, for adding
7294 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007339 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7340 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007341
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342- Issue #1686386: Tuple's tp_repr did not take into account the
7343 possibility of having a self-referential tuple, which is possible
7344 from C code. Nor did object's tp_str consider that a type's tp_str
7345 could do something that could lead to an inifinite recursion.
7346 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7347 issues.

7350 'print' statement to write to a file since the GIL was not released
7351 as needed. Now PyObject_Print() does the right thing along with
7352 various tp_print implementations of the built-in types and those in
7353 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007363 PyObject_Call() never calling back out to Python code to trigger
7364 recursion depth updates/checks. Required the creation of a static

7414
Guido van Rossum143b5642007-03-23 04:58:42 +00007415- Bug #1683368: The object.__init__() and object.__new__() methods are
7416 now stricter in rejecting excess arguments. The only time when
7417 either allows excess arguments is when it is not overridden and the
7418 other one is. For backwards compatibility, when both are
7419 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007420 warning later). Also, type.__init__() insists on the same signature
7421 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007423- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7424 object to complex using its __complex__() method before falling back
7425 to the __float__() method. Therefore, the functions in the cmath
7426 module now can operate on objects that define a __complex__()
7427 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007445- Bug #1678647: write a newline after printing an exception in any
7446 case, even when converting the value to a string failed.
7447
Georg Brandl871f1bc2007-03-12 13:17:36 +00007448- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007449 its argument, if it exists. If not, it will work like before. This
7450 allows customizing the output of dir() in the presence of a
7451 __getattr__().

7461 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007462
Georg Brandlaa2321b2007-03-07 00:40:28 +00007463- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007464 makes the filenames the warning module prints much more sensible
7465 when a PYTHONSTARTUP file is used.

7479 sq_ass_slice instead of the sq_slice slot.
7480
Georg Brandl3ee81df2008-05-17 18:14:43 +00007481- When printing an unraisable error, don't print exceptions. before

8049
Georg Brandl92a6bae2007-03-13 17:43:32 +00008050- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008051 are set for invalid interpolation sequences that would lead to

8108 TestCase and TestSuite subclasses (not instances) are no longer
8109 accepted in TestSuite.addTest(). This should cause no

8112 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008399 that the SMTP.starttls() caller no longer needs to call ehlo()
8400 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008401 does not claim to support starttls. Adds the
8402 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008501 time so that opening a database previously created with the DB_DUP
8502 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8503 opens. Specifically: dictionary assignment to a DB object will

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008785- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008786 periodic threadstate and signal checking in tight loops. By
8787 default, this option is turned-off. It should only be enabled in
8788 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008846- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8847 to ``PyTuple_SetItem``, it can be used to populate a brand new

8862 of w# format code incorrectly truncated the length to an int, even
8863 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8864 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008894- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8895 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
