Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000289 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
290 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
291 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

311Core and Builtins
312-----------------
313
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000314- Issue #7301: Add environment variable $PYTHONWARNINGS.
315
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000316- Issue #8329: Don't return the same lists from select.select when no fds are
317 changed.
318
Georg Brandlfee0f442010-05-22 21:26:21 +0000319- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000320 on 64-bit machines. The shift count for either left or right shift is
321 permitted to be up to sys.maxsize.
322
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000323- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000327- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
328
Georg Brandlfee0f442010-05-22 21:26:21 +0000329- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
330 with a non-empty format string. This is an effort to future-proof user
331 code. If a derived class does not currently implement __format__ but later
332 adds its own __format__, it would most likely break user code that had
333 supplied a format string. This will be changed to a DeprecationWaring in
334 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000335

366
Georg Brandlfee0f442010-05-22 21:26:21 +0000367- Issue #8257: The Decimal construct now accepts a float instance directly,
368 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000369
370 >>> Decimal(1.1)
371 Decimal('1.100000000000000088817841970012523233890533447265625')
372
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000373- collections.Counter() now supports a subtract() method.
374
Georg Brandlfee0f442010-05-22 21:26:21 +0000375- The functools module now has a total_ordering() class decorator to simplify
376 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000377
Georg Brandlfee0f442010-05-22 21:26:21 +0000378- The functools module also adds cmp_to_key() as a tool to transition old-style
379 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000380
Georg Brandlfee0f442010-05-22 21:26:21 +0000381- Issue #8294: The Fraction constructor now accepts Decimal and float instances
382 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000383
Georg Brandlfee0f442010-05-22 21:26:21 +0000384- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
385 InvalidOperation instead of returning False. (Comparisons involving a quiet
386 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
387 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000388
Georg Brandlfee0f442010-05-22 21:26:21 +0000389- Issue #2531: Comparison operations between floats and Decimal instances now
390 return a result based on the numeric values of the operands; previously they
391 returned an arbitrary result based on the relative ordering of id(float) and
392 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000393
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000394- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000395 argument `-` which tells it to read files to compile from stdin. Each line is
396 read on demand and the named file is compiled immediately. (Original patch by
397 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000398
Georg Brandlfee0f442010-05-22 21:26:21 +0000399- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000402- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
403 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000404 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000406- Comparisons using one of <, <=, >, >= between a complex instance and a
407 Fractions instance now raise TypeError instead of returning True/False. This
408 makes Fraction <=> complex comparisons consistent with int <=> complex, float
409 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000410

Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000420- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000421 didn't support chflags() (for example ZFS under FreeBSD). The error is now
422 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000423
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000424- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000464- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000465 for ``TimedRotatingFileHandler`` by using the modification time of an existing
466 log file to compute the next rollover time. If the log file does not exist,
467 the current time is used as the basis for the computation.

514 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000516 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
517 inconsistent: __int__ was used for some integer codes but not for others, and
518 the set of integer codes for which it was used differed between native packing
519 and standard packing.)

744 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000745 library would return a bogus result; on Solaris, it was possible to crash the
746 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000759- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
760 and add the additional members returned in an OSVERSIONINFOEX structure. The
761 new members are service_pack_major, service_pack_minor, suite_mask, and
762 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000764- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
765 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
766 returning NULL. The macro now returns a statically allocated empty string
767 instead.

777 strings,
778 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
779 numeric strings corresponding to subnormal values,
780 (3) a memory leak for some values large enough to cause overflow, and
781 (4) a number of flaws that could lead to incorrectly rounded results.
782
783- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
784 option is not used.

796 interpreter shutdown.
797
Georg Brandlba83f822010-03-14 09:50:54 +0000798- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
799 XML processing instructions and comments. These raw characters are allowed
800 by the XML specification, and are necessary when outputting e.g. PHP code in
801 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000809- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000810 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000811 Also, raise ValueError rather than TypeError when an unknown TIPC address
812 type is specified. Patch by Brian Curtin.
813
Vinay Sajip28c382f2010-02-04 18:48:53 +0000814- logging: Implemented PEP 391.
815
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000816- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000817 file position when calling `truncate()`. It would previously change the file
818 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000819 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
820
Benjamin Petersone06f7112010-01-28 02:15:02 +0000821- UserDict is now a new-style class.
822
Georg Brandlba83f822010-03-14 09:50:54 +0000823- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
824 class used to represent files stored inside an archive. The new
825 implementation is significantly faster and can be wrapped in a
826 ``io.BufferedReader`` object for more speedups. It also solves an issue
827 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
828 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000829
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000830- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Georg Brandlba83f822010-03-14 09:50:54 +0000835- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
836 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000837
Georg Brandlba83f822010-03-14 09:50:54 +0000838- Issue #7748: Since unicode values are supported for some metadata options in
839 Distutils, the DistributionMetadata get_* methods will now return an utf-8
840 encoded string for them. This ensures that the upload and register commands
841 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000842
Georg Brandlba83f822010-03-14 09:50:54 +0000843- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000844 headers in multipart/signed MIME parts, which fixes one of the sources of
845 invalid modifications to such parts by Generator.

915Core and Builtins
916-----------------
917
Georg Brandlba83f822010-03-14 09:50:54 +0000918- The ``__complex__()`` method is now looked up on the class of instances to
919 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000920
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000921- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
922 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
923
Mark Dickinson1b34d252010-01-01 17:27:30 +0000924- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000925 DeprecationWarning when passed a float argument where an integer was expected.
926 These functions and methods now raise TypeError instead. The majority of the
927 effects of this change are in the extension modules, but some core functions
928 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
929 and many unicode/str methods.

940 used to drop the time part of the result.
941
Georg Brandlba83f822010-03-14 09:50:54 +0000942- Issue #1811: Improve accuracy and cross-platform consistency for true division
943 of integers: the result of a/b is now correctly rounded for ints a and b (at
944 least on IEEE 754 platforms), and in particular does not depend on the
945 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000946
Georg Brandlba83f822010-03-14 09:50:54 +0000947- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +0000952 executables on OSX.
953
Georg Brandlba83f822010-03-14 09:50:54 +0000954 These executables now work properly with the arch(1) command: ``arch -ppc
955 python`` will start a universal binary version of python in PPC mode (unlike
956 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000957

971 allowing for a maximum number of tasks within the pool to be completed by the
972 worker before that worker is terminated, and a new one created to replace it.

1096 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001097

1099 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001111
Georg Brandlba83f822010-03-14 09:50:54 +00001112- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1113 decimal string that's guaranteed to round back to x under correct rounding
1114 (with round-half-to-even rounding mode). Previously it gave a string based on
1115 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1116 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1117 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001118
Georg Brandlba83f822010-03-14 09:50:54 +00001119- Issue #7117: On almost all platforms: float-to-string and string-to-float
1120 conversions within Python are now correctly rounded. Places these conversions
1121 occur include: str for floats and complex numbers; the float and complex
1122 constructors; old-style and new-style numeric formatting; serialization and
1123 deserialization of floats and complex numbers using marshal, pickle and json;
1124 parsing of float and imaginary literals in Python code; Decimal-to-float
1125 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001126
Georg Brandlba83f822010-03-14 09:50:54 +00001127 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1128 providing correctly-rounded strtod and dtoa C functions. This code is
1129 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1130 the C compiler. There may be a small number of platforms on which correct
1131 operation of this code cannot be guaranteed, so the code is not used: notably,
1132 this applies to platforms where the C double format is not IEEE 754 binary64,
1133 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1134 and Python's configure script is unable to determine how to change the FPU
1135 precision. On these platforms conversions use the platform strtod and dtoa,
1136 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001137
Georg Brandlba83f822010-03-14 09:50:54 +00001138- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1139 uses the correctly-rounded string <-> float conversions described above (when
1140 available), and so produces correctly rounded results that will display nicely
1141 under the float repr. There are two related small changes: (1) round now
1142 accepts any class with an ``__index__()`` method for its second argument (but
1143 no longer accepts floats for the second argument), and (2) an excessively
1144 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1145 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001287
Georg Brandlba83f822010-03-14 09:50:54 +00001288 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1289 (2) parsing of strings representing infinities and nans was locale aware; and
1290 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001292- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1293 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1294 but with at least one decimal point and with a default precision
1295 of 12. Previously, the behavior the same but with a default precision of 6.
1296 This more closely matches ``str()``, and reduces surprises when adding
1297 alignment flags to the empty presentation type. This also affects the new
1298 complex.__format__ in the same way.
1299
1300- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1301 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001363 untrackable objects are not tracked by the garbage collector. This can reduce

1372 internal representation of integers, for performance reasons. Base 2**30 is
1373 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00001461- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001462 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001463
Skip Montanarof205c132008-12-23 03:30:15 +00001464- Added test case to ensure attempts to read from a file opened for writing
1465 fail.
1466
Georg Brandlba83f822010-03-14 09:50:54 +00001467- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1468 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00001481- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1482 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1483 instances. On a typical machine this saves 3 bytes of memory (on average) per
1484 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001486- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1487 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1488 instead of throwing a MemoryError.
1489
Georg Brandlba83f822010-03-14 09:50:54 +00001490- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00001493- Issue #4367: Python would segfault during compiling when the unicodedata
1494 module couldn't be imported and \N escapes were present.
1495
Georg Brandlba83f822010-03-14 09:50:54 +00001496- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1497 file objects with closefd=False. The file descriptor is still kept open but
1498 the file object behaves like a closed file. The ``FileIO`` object also got a
1499 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001501- Issue #4348: Some bytearray methods returned that didn't cause any change to
1502 the bytearray, returned the same bytearray instead of a copy.
1503
Georg Brandlba83f822010-03-14 09:50:54 +00001504- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00001516- Issue #4209: Enabling unicode_literals and the print_function in the same
1517 __future__ import didn't work.
1518
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001519- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001520 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001521
Georg Brandlba83f822010-03-14 09:50:54 +00001522- On windows, ``os.chdir()`` given unicode was not working if
1523 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1524 this code path is really executed because I cannot move to such directory on
1525 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001526
Georg Brandlba83f822010-03-14 09:50:54 +00001527- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1528 element is temporarily replaced with an equivalent frozenset. But the
1529 eventual KeyError would always report the empty ``frozenset()`` as the missing
1530 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001547- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1548 returned them on 64bit platforms.
1549
Walter Dörwalded960ac2009-05-03 22:36:33 +00001550- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1551 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1552 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1553 of using the replace error handler in PyUnicode_DecodeUTF8().
1554
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001555- Issue #3739: The unicode-internal encoder now reports the number of characters
1556 consumed like any other encoder (instead of the number of bytes).
1557
Georg Brandlba83f822010-03-14 09:50:54 +00001558- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1559 allocator will be automatically disabled when running under Valgrind. This
1560 gives improved memory leak detection when running under Valgrind, while taking
1561 advantage of pymalloc at other times.

Antoine Pitrou4698d992009-05-31 14:20:14 +00002808- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2809 regression tests in parallel, shortening the total runtime.
2810
Georg Brandlba83f822010-03-14 09:50:54 +00002811- Issue #5354: New test support function import_fresh_module() makes it easy to
2812 import both normal and optimised versions of modules. test_heapq and
2813 test_warnings have been adjusted to use it, tests for other modules with both
2814 C and Python implementations in the stdlib can be adjusted to use it over
2815 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002823- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2824 should cause a test to be skipped are now done using import_module from test
2825 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002926- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2927
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002928- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2929 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2930 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2931 ``printf`` function, whereas PyString_FromFormat has an independent
2932 implementation and uses "%zd" on all platforms for size_t values.
2933 This makes a difference on win64, where ``printf`` needs "%Id" to display
2934 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002936- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2940 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002951 was correctly parsed but parsing of subsequent arguments failed.
2952
Vinay Sajip35e3b032008-09-01 14:33:59 +00002953- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002954 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2955 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2956 when given a tuple of classes as second argument, were looking up
2957 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2958 type object.

3102Core and Builtins
3103-----------------
3104
Guido van Rossumf8402962008-08-20 15:01:50 +00003105- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3106 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3107 extensions do not automatically benefit from the class attribute
3108 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3109 to their tp_flags field if they care. This is a backwards
3110 compatibility feature; in 3.0, all types will use the cache by
3111 default.
3112
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003113- Keyword arguments can now follow starred arguments. (``f(a, *args,
3114 keyword=23)`` is now valid syntax.)
3115
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003116- ctypes function pointers that are COM methods have a boolean True
3117 value again.
3118
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003119- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3120 by denying s# to parse objects that have a releasebuffer procedure,
3121 and introducing s*.
3122
Georg Brandl1e13ea92008-08-11 09:07:59 +00003123- Issue #3537: Fix an assertion failure when an empty but presized dict
3124 object was stored in the freelist.
3125
Mark Dickinsonb6467572008-08-04 21:30:09 +00003126- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3127 ValueError consistently across platforms.
3128
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003129- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3130 (64bit Unix, for example), unichr() would truncate its argument and return
3131 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3132
Neal Norwitze7d8be82008-07-31 17:17:14 +00003133- Apply security patches from Apple.
3134
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003135- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3136 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3137
Antoine Pitrou92f82162008-07-25 22:22:08 +00003138- Issue #1819: function calls with several named parameters are now on
3139 average 35% faster (as measured by pybench).
3140
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003141- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3142 the python debugger steps into a class statement: the free variables (local
3143 variables defined in an outer scope) would be deleted from the outer scope.
3144
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003145- Issue #2620: Overflow checking when allocating or reallocating memory
3146 was not always being done properly in some python types and extension
3147 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3148 all been updated to perform better checks and places in the code that
3149 would previously leak memory on the error path when such an allocation
3150 failed have been fixed.

3153-------
3154
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003155- Issue #3612: Added some missing basic types in ctypes.wintypes.
3156
Benjamin Petersone977ad42008-08-20 01:42:01 +00003157- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3158 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3159
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003160- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3161 version reported by these tools does not necessarily follow the python
3162 version numbering scheme, so the module is less strict when parsing it.
3163
Nick Coghlanf70385a2008-08-18 12:42:46 +00003164- Issue #2235: Added Py3k warnings for types which will become unhashable
3165 under the stricter __hash__ inheritance rules in 3.0. Several types
3166 which did not meet the rules for hash invariants and were already
3167 unhashable in 3.0 have now been explicitly flagged as unhashable in
3168 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3169 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3170
Brett Cannon88f801d2008-08-18 00:46:22 +00003171- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3172 imported into the module but exposed as part of the module's API.
3173
Brett Cannon7b96f072008-08-18 00:41:11 +00003174- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3175
Brett Cannon46225e72008-08-18 00:36:52 +00003176- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3177
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003178- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3179
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003180- Issue #3575: Incremental decoder's decode function now takes bytearray
3181 by using 's*' instead of 't#'.
3182
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003183- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003184 fails unicode conversion on 2nd parameter. (windows only)
3185
Facundo Batista94f243a2008-08-17 03:38:39 +00003186- Issue 2464. urllib2 now supports a malformation in the URL received
3187 in a redirect.
3188
Brett Cannonabe423e2008-08-16 21:47:07 +00003189- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003190 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003191
Facundo Batistaeb90b782008-08-16 14:44:07 +00003192- Issue #2776: fixed small issue when handling an URL with double slash
3193 after a 302 response in the case of not going through a proxy.
3194
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003195- Issue #2676: in the email package, content-type parsing was hanging on
3196 pathological input because of quadratic or exponential behaviour of a
3197 regular expression.
3198
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003199- Issue #3476: binary buffered reading through the new "io" library is now
3200 thread-safe.
3201
Brett Cannonbf3157b2008-08-14 05:00:03 +00003202- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3203 since mimetools itself is deprecated. Because modules are cached, all
3204 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3205
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003206- Issue #3134: shutil referenced undefined WindowsError symbol.
3207
Robert Schuppenies14646332008-08-10 11:01:53 +00003208- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3209 menu entries were not deleted.
3210
Brett Cannon83e81842008-08-09 23:30:55 +00003211- Copied the implementation of reduce() to _functools.reduce() to have a
3212 version that did not raise a DeprecationWarning under -3.
3213
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003214- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3215 a MemoryError rather than silently stop the iteration.
3216
Guido van Rossum59ce9012008-08-09 14:55:34 +00003217- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3218 to _sre.compile() will now be rejected. This should not affect anybody
3219 since the re.compile() function never generates invalid re-bytecode.
3220
Skip Montanaroa032bf42008-08-08 22:52:51 +00003221- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3222 upon first access it can be automatically initialized from the csv file if
3223 it wasn't initialized during instantiation.
3224
Brett Cannon3aa2a492008-08-06 22:28:09 +00003225- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3226 the reload() built-in has been removed.
3227
Brett Cannon7e30b672008-08-04 21:52:25 +00003228- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003229 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003230 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3231 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3232 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3233 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3234 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003235
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003236- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3237 raised an AttributeError.
3238
Benjamin Peterson01a24322008-07-28 23:35:27 +00003239- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003240 asking for a specific length. This problem only affected files opened
3241 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003242
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003243- Issue #3449: Update decimal module to use most recent specification
3244 (v. 1.68) and tests (v. 2.58) from IBM.
3245
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003246- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3247
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003248- Issue 1592: Improve error reporting when operations are attempted
3249 on a closed shelf.

3252
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003253- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3254
3255- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3256 invalid arguments.
3257
3258- Issue #3302: Fix several crashes when calling locale's gettext functions
3259 with None arguments.
3260
3261- Issue #3389: Allow resolving dotted names for handlers in logging
3262 configuration files.
3263
3264- Deprecate the sunaudio module for removal in Python 3.0.
3265
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003266- Issue #3394: zipfile.writestr sets external attributes when passed a
3267 file name rather than a ZipInfo instance, so files are extracted with
3268 mode 0600 rather than 000 under Unix.
3269
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003270- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3271 argument in python 2.5, this broke code that subclassed Popen to include its
3272 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3280-------------
3281
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003282- Issue #2235: the C API function PyObject_HashNotImplemented and its
3283 interaction with the tp_hash slot (added in 2.6b2) are now documented
3284
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003285- Issue #643841: The language reference now provides more detailed
3286 coverage of the lookup process for special methods. The disclaimers
3287 regarding lack of coverage of new-style classes have also been
3288 removed, since the coverage is now fairly reasonable.

3297-----------------
3298
Georg Brandl3e483f62008-07-16 22:57:41 +00003299- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3300 its methods now allow for items objects that can be converted to
3301 an integer using operator.index().
3302
Mark Dickinson64b7e502008-07-16 09:40:03 +00003303- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3304 produced a ValueError instead of giving the correct float.
3305
Eric Smitha5fa5a22008-07-16 00:11:49 +00003306- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3307 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3308
Mark Dickinson7103aa42008-07-15 19:08:33 +00003309- Issue #3008: the float type has a new instance method 'float.hex'
3310 and a new class method 'float.fromhex' to convert floating-point
3311 numbers to and from hexadecimal strings, respectively.
3312
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003313- Issue #2235: __hash__ is once again inherited by default. To allow
3314 collections.Hashable to remain meaningful in the presence of the
3315 default hash implementation (object.__hash__), it is now possible
3316 to explicit block inheritance of hash by setting __hash__=None at
3317 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3318 level.
3319
Nick Coghlanb028f502008-07-13 14:52:36 +00003320- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3321 the parent module cannot be found while performing an absolute import.
3322 This means that an incorrectly defined __package__ attribute will
3323 now only prevent relative imports in that module rather than causing
3324 all imports from that module to fail.
3325
Nick Coghlan14ff9942008-07-08 14:21:42 +00003326- Issue #2517: Allow unicode messages in Exceptions again by correctly
3327 bypassing the instance dictionary when looking up __unicode__ on
3328 new-style classes.
3329
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003330- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3331 set to a custom object whose write() method happens to install
3332 another file in sys.stdout.
3333
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003334- Issue #3088: Corrected a race condition in classes derived from
3335 threading.local: the first member set by a thread could be saved in
3336 another thread's dictionary.
3337
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003338- Issue #3004: Minor change to slice.indices(): the start and stop
3339 arguments are now treated identically, making the behaviour easier
3340 to describe and understand. For example, slice(None, -10,
3341 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3342 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3343 10, -1).
3344
Georg Brandl278fc502008-07-19 12:46:12 +00003345- Issue #3219: Calling a function with repeated keyword arguments,
3346 f(a=2, a=23), would not cause a syntax error. This was a regression
3347 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003348
Georg Brandl278fc502008-07-19 12:46:12 +00003349- Issue #2862: Make int and float freelist management consistent with
3350 other freelists. Changes their CompactFreeList apis into
3351 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003352

3354-------
3355
Thomas Heller57adf222008-08-14 19:10:48 +00003356- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3357 api functions without holding the GIL, which could lead to a fatal
3358 error when they failed.
3359
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003360- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003368- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3369 ForkingPickler.register() to resolve conflict with ctypes.
3370
Vinay Sajip51e65192008-07-18 09:01:10 +00003371- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003372
Thomas Heller880f5292008-07-15 19:39:38 +00003373- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3374 a valid dlerror() message.
3375
Thomas Heller2bad6572008-07-15 17:19:50 +00003376- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3377 incomplete structure was created.
3378
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003379- Issue #3339: dummy_thread.acquire() should not return None.
3380
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003381- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3382
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003383- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003384
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003385- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3386 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003387 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003388 content-length. The problem had been corrected in the 2.4 branch, but never

3796 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003797 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003798
3799 This is controlled by the configure argument ``--with-universal-archs``:
3800
3801 - ``--with-universal-archs=all``: install 4-way universal
3802
3803 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3804
3805 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3806
3807 This option should be used in combination with ``--enable-universalsdk=``.
3808
3809 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003859- Issue #1631171: Re-implement the 'warnings' module in C (the
3860 original Python code has been kept as backup). This will allow for
3861 using the 'warning's machinery in such places as the parser where
3862 use of pure Python code is not possible. Both the ``showarning()``
3863 and ``formatwarning()`` gain an optional 'line' argument which is
3864 not called by default for backwards-compatibility reasons. Setting
3865 ``warnings.showwarning()`` to an implementation that lacks support
3866 for the ``line`` argument will raise a DeprecationWarning.

3890
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003891- The getpass module has been improved on Unix. It now uses /dev/tty
3892 by default and uses stderr instead of stdout. A GetPassWarning is
3893 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003909 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Issue #2550: The approach used by client/server code for obtaining
3930 ports to listen on in network-oriented tests has been refined in an
3931 effort to facilitate running multiple instances of the entire
3932 regression test suite in parallel without issue.
3933 test_support.bind_port() has been fixed such that it will always
3934 return a unique port -- which wasn't always the case with the
3935 previous implementation, especially if socket options had been set
3936 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3937 new implementation of bind_port() will actually raise an exception
3938 if it is passed an AF_INET/SOCK_STREAM socket with either the
3939 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3940 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3941 the socket it's been passed. This currently only applies to
3942 Windows. This option prevents any other sockets from binding to the
3943 host/port we've bound to, thus removing the possibility of the
3944 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3945 when a second SOCK_STREAM socket binds and accepts to a host/port
3946 that's already been bound by another socket. The optional preferred
3947 port parameter to bind_port() has been removed. Under no
3948 circumstances should tests be hard coding ports!

3950 test_support.find_unused_port() has also been introduced, which will
3951 pass a temporary socket object to bind_port() in order to obtain an
3952 unused port. The temporary socket object is then closed and
3953 deleted, and the port is returned. This method should only be used
3954 for obtaining an unused port in order to pass to an external program
3955 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3956 a parameter to a server-oriented class that doesn't give you direct
3957 access to the underlying socket used.
3958
3959 Finally, test_support.HOST has been introduced, which should be used
3960 for the host argument of any relevant socket calls (i.e. bind and
3961 connect).

3969 suite to run in parallel without issue.

4235Core and builtins
4236-----------------
4237
Fred Drakea8ee94b2008-03-01 02:45:07 +00004238- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004239 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004240
Georg Brandlad61bc82008-02-23 15:11:18 +00004241- Issue #2067: file.__exit__() now calls subclasses' close() method.
4242
4243- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004244
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004245- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004246 issue 215555 for a discussion.
4247
Eric Smitha73fbe72008-02-23 03:09:44 +00004248- Added the future_builtins module, which contains hex() and oct().
4249 These are the PEP 3127 version of these functions, designed to be
4250 compatible with the hex() and oct() builtins from Python 3.0. They
4251 differ slightly in their output formats from the existing, unchanged
4252 Python 2.6 builtins. The expected usage of the future_builtins
4253 module is:
4254 from future_builtins import hex, oct
4255
Eric Smith7ef40bf2008-02-20 23:34:22 +00004256- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4257 exponents for exponents with absolute value < 100. Follows C99
4258 standard. This is a change on Windows, which would use 3 digits.
4259 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4260 so that any alterations it does to the resulting string will be
4261 available in stringlib/formatter.h (for float.__format__).
4262
Eric Smith5a3c1352008-02-19 13:21:56 +00004263- Implemented PEP 3101, Advanced String Formatting. This adds a new
4264 builtin format(); a format() method for str and unicode; a
4265 __format__() method to object, str, unicode, int, long, float, and
4266 datetime; the class string.Formatter; and the C API
4267 PyObject_Format().
4268
Georg Brandl3ee81df2008-05-17 18:14:43 +00004269- Fixed several potential crashes, all caused by specially crafted
4270 __del__ methods exploiting objects in temporarily inconsistent
4271 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004272
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004273- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274 prevent a possible crash: an Abstract Base Class would try to access
4275 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004276
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Fixed repr() and str() of complex numbers with infinity or nan as
4278 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004279
Georg Brandl3ee81df2008-05-17 18:14:43 +00004280- Clear all free lists during a gc.collect() of the highest generation
4281 in order to allow pymalloc to free more arenas. Python may give back
4282 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004283
Georg Brandl3ee81df2008-05-17 18:14:43 +00004284- Issue #2045: Fix an infinite recursion triggered when printing a
4285 subclass of collections.defaultdict, if its default_factory is set
4286 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004287
Christian Heimesf75dbef2008-02-08 00:11:31 +00004288- Fixed a minor memory leak in dictobject.c. The content of the free
4289 list was not freed on interpreter shutdown.
4290
Georg Brandl21e99f42010-03-07 15:23:59 +00004291- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004292 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004293
Georg Brandl3ee81df2008-05-17 18:14:43 +00004294- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4295 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004296 to compact the internal free lists of pre-allocted ints and floats.
4297
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4299 calls. Python expected the return type int but the fork familie
4300 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004301
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4303 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004304
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4306 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004307
Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4309 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004310
Georg Brandl3ee81df2008-05-17 18:14:43 +00004311- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4312 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004313
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Patch #1473257: generator objects gain a gi_code attribute. This is
4315 the same object as the func_code attribute of the function that
4316 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Issue #1920: "while 0" statements were completely removed by the
4319 compiler, even in the presence of an "else" clause, which is
4320 supposed to be run when the condition is false. Now the compiler
4321 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004322
Guido van Rossumeead05f2008-01-24 18:21:02 +00004323- A few crashers fixed: weakref_in_del.py (issue #1377858);
4324 loosing_dict_ref.py (issue #1303614, test67.py);
4325 borrowed_ref_[34].py (not in tracker).
4326
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004327- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004328 suppressed while an extension is loaded by calling SetErrorMode in
4329 dynload_win.c. The error is still reported properly.
4330
Georg Brandl3ee81df2008-05-17 18:14:43 +00004331- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004332 several extension methods and modules do not work without unicode
4333 support.
4334
Georg Brandl26543b12008-01-21 18:36:51 +00004335- Issue #1882: when compiling code from a string, encoding cookies in the
4336 second line of code were not always recognized correctly.
4337
Georg Brandl14404b62008-01-19 19:27:05 +00004338- Issue #1679: "0x" was taken as a valid integer literal.
4339
Georg Brandl6caad7d2008-01-26 14:19:22 +00004340- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004341 added.
4342
Christian Heimesc94e2b52008-01-14 04:13:37 +00004343- sys.float_info / PyFloat_GetInfo: The floating point information
4344 object was converted from a dict to a specialized structseq object.
4345
Georg Brandl3ee81df2008-05-17 18:14:43 +00004346- Patch #1816: Added sys.flags structseq. It exposes the status of
4347 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004348
Georg Brandl3ee81df2008-05-17 18:14:43 +00004349- Objects/structseq.c: Implemented new structseq representation. The
4350 patch makes structseqs (e.g. the return value of os.stat) more
4351 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004352
Georg Brandl3ee81df2008-05-17 18:14:43 +00004353- Patch #1700288: added a type attribute cache that caches method
4354 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004355
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004356- Bug #1776: __import__() no longer accepts filenames on any platform.
4357 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004358
Georg Brandlaed6c662008-01-07 17:25:53 +00004359- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4360
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4362 envvar and sys.dont_write_bytecode attribute. All these can be set
4363 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- Improve some exception messages when Windows fails to load an
4366 extension module. Now we get for example '%1 is not a valid Win32
4367 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004368
Georg Brandl3ee81df2008-05-17 18:14:43 +00004369- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004371- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4372 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004373
Christian Heimes0a8143f2007-12-18 23:22:54 +00004374- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004375 and INF. float("nan"), float("inf") and float("-inf") now work on
4376 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004377
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378- Compiler now generates simpler and faster code for dictionary
4379 literals. The oparg for BUILD_MAP now indicates an estimated
4380 dictionary size. There is a new opcode, STORE_MAP, for adding
4381 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004382
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383- Issue #1638: %zd configure test fails on Linux.

4393
Nick Coghlanef01d822007-12-03 12:55:17 +00004394- PEP 366: Allow explicit relative imports when executing modules
4395 inside packages with the -m switch via a new module level
4396 __package__ attribute.
4397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Issue #1402: Fix a crash on exit, when another thread is still
4399 running, and if the deallocation of its frames somehow calls the
4400 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004401

4411 file can now be directly executed by passing their name to the
4412 interpreter. The directory/zipfile is automatically inserted as the
4413 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004414
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415- Issue #1265: Fix a problem with sys.settrace, if the tracing
4416 function uses a generator expression when at the same time the
4417 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004418
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004419- sets and frozensets now have an isdisjoint() method.
4420
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004421- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004423- Fix warnings found by the new version of the Coverity checker.
4424
Georg Brandl21e99f42010-03-07 15:23:59 +00004425- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004426 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4427 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004428
Georg Brandl3ee81df2008-05-17 18:14:43 +00004429- Issue #1686386: Tuple's tp_repr did not take into account the
4430 possibility of having a self-referential tuple, which is possible
4431 from C code. Nor did object's tp_str consider that a type's tp_str
4432 could do something that could lead to an inifinite recursion.
4433 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4434 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004435
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Issue #1164: It was possible to trigger deadlock when using the
4437 'print' statement to write to a file since the GIL was not released
4438 as needed. Now PyObject_Print() does the right thing along with
4439 various tp_print implementations of the built-in types and those in
4440 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004441
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Issue #1147: Exceptions were directly allowing string exceptions in
4443 their throw() method even though string exceptions no longer
4444 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00004449- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450 PyObject_Call() never calling back out to Python code to trigger
4451 recursion depth updates/checks. Required the creation of a static
4452 RuntimeError instance in case normalizing an exception put the
4453 recursion check value past its limit. Fixes crashers
4454 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- Patch #1031213: Decode source line in SyntaxErrors back to its

4460 with %G.
4461
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462- Prevent expandtabs() on string and unicode objects from causing a
4463 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004469- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004470 __*__ attributes. (Some already existed, e.g., __doc__ and
4471 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004472
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004473- Add -3 option to the interpreter to warn about features that are
4474 deprecated and will be changed/removed in Python 3.0.
4475
Georg Brandl2134e752007-05-21 20:34:16 +00004476- Patch #1686487: you can now pass any mapping after '**' in function
4477 calls.
4478
Collin Winter62903052007-05-18 23:11:24 +00004479- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004480 "except E as target:". This is to provide forwards compatibility
4481 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004482
Brett Cannon229cee22007-05-05 01:34:02 +00004483- Deprecate BaseException.message as per PEP 352.
4484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004486 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004487
Vinay Sajip8549ce32007-05-06 17:53:37 +00004488- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004489 setting a plain string, ie don't expand to single letter identifiers.
4490
Raymond Hettinger13936692007-04-11 18:40:58 +00004491- Request #1191699: Slices can now be pickled.
4492
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004493- Request #1193128: str.translate() now allows a None argument for
4494 translations that only remove characters without re-mapping the
4495 remaining characters.
4496
Georg Brandl5cb76c12007-03-21 09:00:39 +00004497- Patch #1682205: a TypeError while unpacking an iterable is no longer
4498 masked by a generic one with the message "unpack non-sequence".
4499
Neal Norwitzaa754b72007-03-21 06:39:48 +00004500- Remove unused file Python/fmod.c.
4501
Guido van Rossum143b5642007-03-23 04:58:42 +00004502- Bug #1683368: The object.__init__() and object.__new__() methods are
4503 now stricter in rejecting excess arguments. The only time when
4504 either allows excess arguments is when it is not overridden and the
4505 other one is. For backwards compatibility, when both are
4506 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004507 warning later). Also, type.__init__() insists on the same signature
4508 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4511 object to complex using its __complex__() method before falling back
4512 to the __float__() method. Therefore, the functions in the cmath
4513 module now can operate on objects that define a __complex__()
4514 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004515
Georg Brandl3ee81df2008-05-17 18:14:43 +00004516- Patch #1623563: allow __class__ assignment for classes with
4517 __slots__. The old and the new class are still required to have the
4518 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004519

4524 ``object.__reduce_ex__()`` is called with an object that is faking
4525 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004526
Georg Brandl3ee81df2008-05-17 18:14:43 +00004527- Patch #1680015: Don't modify __slots__ tuple if it contains an
4528 unicode name.

4531
Georg Brandl7b9c5552007-03-12 14:30:05 +00004532- Bug #1678647: write a newline after printing an exception in any
4533 case, even when converting the value to a string failed.
4534
Georg Brandl871f1bc2007-03-12 13:17:36 +00004535- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004536 its argument, if it exists. If not, it will work like before. This
4537 allows customizing the output of dir() in the presence of a
4538 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004539
Collin Winter276887b2007-03-12 16:11:39 +00004540- Patch #922167: Python no longer segfaults when faced with infinitely
4541 self-recursive reload() calls (as reported by bug #742342).
4542

4547 parthensized forms. This means complex(repr(x)) now works instead of
4548 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004549
Georg Brandlaa2321b2007-03-07 00:40:28 +00004550- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004551 makes the filenames the warning module prints much more sensible
4552 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004553
Georg Brandl49aafc92007-03-07 00:34:46 +00004554- Variant of patch #697613: don't exit the interpreter on a SystemExit
4555 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004556 variable is given, but break into the interactive interpreter just
4557 like on other exceptions or normal program exit.

4563 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004564
Georg Brandl0fca97a2007-03-05 22:28:08 +00004565- Patch #1674228: when assigning a slice (old-style), check for the
4566 sq_ass_slice instead of the sq_slice slot.
4567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- When printing an unraisable error, don't print exceptions. before
4569 the name. This duplicates the behavior whening normally printing
4570 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Bug #1377858: Fix the segfaulting of the interpreter when an object
4579 created a weakref on itself during a __del__ call for new-style
4580 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00004581

5179 Python would crash instead of raising an error.
5180

5193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- unittest now verifies more of its assumptions. In particular,
5195 TestCase and TestSuite subclasses (not instances) are no longer
5196 accepted in TestSuite.addTest(). This should cause no
5197 incompatibility since it never made sense with ordinary subclasses
5198 -- the failure just occurred later, with a more cumbersome
5199 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5481 with RFC 3207 and forgets any knowledge obtained from the server not
5482 obtained from the TLS negotiation itself. Patch contributed by Bill
5483 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005484
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005486 that the SMTP.starttls() caller no longer needs to call ehlo()
5487 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488 does not claim to support starttls. Adds the
5489 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5570 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5571 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005588 time so that opening a database previously created with the DB_DUP
5589 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5590 opens. Specifically: dictionary assignment to a DB object will
5591 replace all values for a given key when the database allows
5592 duplicate values. DB users should use DB.put(k, v) when they want
5593 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005594

5600 characters with ASCII value less than 32. Also, it correctly quotes
5601 dots only if they occur on a single line, as opposed to the previous
5602 behavior of quoting dots if they are the second character of any
5603 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005604

5926-----
5927
Georg Brandl3ee81df2008-05-17 18:14:43 +00005928- Unified naming convention for free lists and their limits. All free
5929 lists in Object/ are named ``free_list``, the counter ``numfree``
5930 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5931 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005932
Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5934 to ``PyTuple_SetItem``, it can be used to populate a brand new
5935 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005936
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005937- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005939- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5940 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5941 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005942
5943- Patch #1720595: add T_BOOL to the range of structmember types.
5944
5945- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5946 ``PyFloat_GetInfo()`` to the float API.
5947
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5949 of w# format code incorrectly truncated the length to an int, even
5950 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5951 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005952
Georg Brandl3ee81df2008-05-17 18:14:43 +00005953- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5954 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005956- PEP 3123: Provide forward compatibility with Python 3.0, while
5957 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5958 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005959
Georg Brandl3ee81df2008-05-17 18:14:43 +00005960- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5961 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005962
5963- Patch #1733960: Allow T_LONGLONG to accept ints.
5964
5965- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5966
Christian Heimes000a0742008-01-03 22:16:32 +00005967- Added a new API function ``PyImport_ImportModuleNoBlock``.

5970
5971- Fix some leftovers from the conversion from int to Py_ssize_t
5972 (relevant to strings and sequences of more than 2**31 items).
5973
5974- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5975 outside of pystate.c and should not be necessary.
5976
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5978 absolute imports. In earlier versions they might have used relative
5979 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005980
Georg Brandl3ee81df2008-05-17 18:14:43 +00005981- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5982 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005983
Georg Brandl3ee81df2008-05-17 18:14:43 +00005984- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5992 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5993 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5994 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005995
Georg Brandl3ee81df2008-05-17 18:14:43 +00005996- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

6008
Georg Brandl3ee81df2008-05-17 18:14:43 +00006009- Removed the macfs module. It had been deprecated since Python 2.5.
6010 This lead to the deprecation of macostools.touched() as it relied
6011 solely on macfs and was a no-op under OS X.
