Georg Brandl4fbc0d82010-11-13 13:25:40 +000061- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
62 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +000063 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +000064 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +000065 encoding and to encode command line arguments on this OS.

70

Victor Stinner22a351a2010-10-14 12:04:34 +000081 descriptor.
82
Georg Brandl66c221e2010-10-14 07:04:07 +000083- Issue #9418: Moved private string methods ``_formatter_parser`` and

177 your app validates with Python <3.2b1+, but not on this version, it is likely

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000439- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

441 Py_Initialize().
442
Georg Brandl27a28582010-10-10 09:49:21 +0000443- All SyntaxErrors now have a column offset and therefore a caret when the error
444 is printed.

Georg Brandl27a28582010-10-10 09:49:21 +0000452- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
453 with a non-empty format string. This is an effort to future-proof user
454 code. If a derived class does not currently implement __format__ but later
455 adds its own __format__, it would most likely break user code that had
456 supplied a format string. This will be changed to a DeprecationWaring in
457 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +0000459- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
460 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
461 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000463- Issue #9210: Configure option --with-wctype-functions was removed. Using the
464 functions from the libc caused the methods .upper() and lower() to become
465 locale aware and created subtly wrong results.
466
Georg Brandl27a28582010-10-10 09:49:21 +0000467- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
468 non-ASCII byte in the format string.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000470- Issue #4617: Previously it was illegal to delete a name from the local
471 namespace if it occurs as a free variable in a nested block. This limitation
472 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
473
Georg Brandl27a28582010-10-10 09:49:21 +0000474- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
475 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
476 Also, the "backslashreplace" error handler now joins surrogate pairs into a
477 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000479- Issue #9757: memoryview objects get a release() method to release the
480 underlying buffer (previously this was only done when deallocating the
481 memoryview), and gain support for the context management protocol.
482
Antoine Pitrou079ce542010-09-08 12:37:10 +0000483- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
484 thread-local storage key.

Georg Brandl27a28582010-10-10 09:49:21 +0000514 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000515 replacement for old handle_accept() and avoids the user to call accept()
516 directly.

Georg Brandl27a28582010-10-10 09:49:21 +0000540 retry the select() loop instead of bailing out. This is because select() can
541 incorrectly report a socket as ready for reading (for example, if it received
542 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +0000622- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000623 it possible for the user to create self-referencing ordered dictionaries which
624 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000625 approach of using weakref proxies so that reference cycles never get created
626 in the first place.

629 encode the value with filesystem encoding and surrogateescape (instead of

634 sys.setfilesystemencoding() creates inconsistencies because it is unable to

652 still return the id of the parent process after it has exited. This process
653 id may even have been reused by another unrelated process.
654
Georg Brandl27a28582010-10-10 09:49:21 +0000655- Issue #9792: In case of connection failure, socket.create_connection() would

Georg Brandl27a28582010-10-10 09:49:21 +0000669 * Update the seed() method to use all of the bits in a string instead of just
670 the hash value. This makes better use of the seed value and assures the
671 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000672
Georg Brandl27a28582010-10-10 09:49:21 +0000673 * Improved the random()-->integer algorithm used in choice(), shuffle(),
674 sample(), randrange(), and randint(). Formerly, it used int(n*random())
675 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000676
677 * Improved documentation of arguments to randrange(). Issue #9379.

828 return characters from the full Unicode range, even on narrow unicode builds
829 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Victor Stinner47fcb5b2010-08-13 23:59:58 +0000849- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +0000850 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
851 objects are output as-is.

Georg Brandl649971e2010-09-05 17:06:50 +0000857- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
858 use PyUnicode_FromFormatV() to format the warning message.

866 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +0000867
Georg Brandl649971e2010-09-05 17:06:50 +0000868- Issue #9416: Fix some issues with complex formatting where the output with no
869 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000870
871 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
872 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

1209 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1210 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions

Georg Brandl62069d32010-07-31 08:56:11 +00001254- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1255 TypeError instead of giving a DeprecationWarning when a float is parsed using
1256 the 'L' code (for long long). (All other integer codes already raise
1257 TypeError in this case.)

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001283- Issue #8748: Fix two issues with comparisons between complex and integer
1284 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001285 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1286 (2) The comparison raised an OverflowError for large integers, leading to
1287 unpredictable exceptions when combining integers and complex objects in sets

1589
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00001590- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
1591 variable argument list. `Py_VA_COPY` is equivalent to C99
1592 `va_copy`, but available on all python platforms.
1593
Mark Dickinsone6fc7402010-08-06 18:55:26 +00001594- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
1595 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
1596 "step = -step" when reversing a slice.
1597
Georg Brandl62069d32010-07-31 08:56:11 +00001598- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

Antoine Pitrou8689a102010-04-01 16:53:15 +00001606- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00001607 function declaration, which was kept for backwards compatibility reasons, is
1608 now removed (the macro was introduced in 1997!).

Georg Brandl62069d32010-07-31 08:56:11 +00001617 PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
1618 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1619 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001620 to match the behaviour of the other integer format codes.
1621
Georg Brandl62069d32010-07-31 08:56:11 +00001622- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.

Georg Brandl62069d32010-07-31 08:56:11 +00001630- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
1631 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
1632 accessing the d_type and d_name members of structures using PyDescr_COMMON.
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +00001633

1646
Georg Brandl62069d32010-07-31 08:56:11 +00001647- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1648 allocator will be automatically disabled when running under Valgrind. This
1649 gives improved memory leak detection when running under Valgrind, while taking
1650 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00001723- The default size of the re module's compiled regular expression cache has been

Antoine Pitrou3060c452010-08-13 16:27:38 +00001725 simply clearing the entire cache on overflow to forgetting the least recently
1726 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001727 applications that use a lot of regular expressions and limits the impact of
1728 the performance hit anytime the cache is exceeded.

1983 operation raises multiple signals and more than one of those signals is
1984 trapped, the specification determines the order in which the signals should be
1985 handled. In many cases this order wasn't being followed, leading to the wrong

Barry Warsawd5f9bf52010-03-31 21:36:22 +00002150- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002151 argument `-` which tells it to read files to compile from stdin. Each line is
2152 read on demand and the named file is compiled immediately. (Original patch by
2153 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00002159- Comparisons using one of <, <=, >, >= between a complex instance and a
2160 Fractions instance now raise TypeError instead of returning True/False. This
2161 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2162 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00002209- subprocess.Popen now has restore_signals and start_new_session features. The
2210 default of restore_signals=True is a new behavior compared to earlier Python
2211 versions. This means that signals such as SIGPIPE are not ignored by default
2212 in subprocesses launched by Python (Issue #1652).

Brett Cannon69194272009-07-20 04:23:48 +00002643- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00002644 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
2645 PyPycLoader inherit from this class and provide implementations in relation to
2646 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002705- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002706 compared to other unix systems. In particular, os.getgroups() does not reflect
2707 any changes made using os.setgroups() but basicly always returns the same
2708 information as the id command. os.getgroups() can now return more than 16
2709 groups on MacOSX.

2735 Prior to this change, timezone adjustment in utctimetuple() could produce
2736 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

2741 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2742 ``datetime.timezone`` instance constructed from the parsed offset. If both
2743 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2744 name, but ``%Z`` data without ``%z`` is discarded.

2748 ``datetime.timezone``, return fixed name and UTC offset from their
2749 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

3371 default precision of 12. Previously, the behavior the same but with
3372 a default precision of 6. This more closely matches str(), and
3373 reduces surprises when adding alignment flags to the empty
3374 presentation type. This also affects the new complex.__format__ in
3375 the same way.
3376
Martin v. Löwis011e8422009-05-05 04:43:17 +00003377- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

3394 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3395 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00003397- Issue #1588: Add complex.__format__. For example,

Mark Dickinsone6a076d2009-04-18 11:48:33 +00003418- Issue #1869 (and many duplicates): make round(x, n) correctly
3419 rounded for a float x, by using the decimal <-> binary conversions
3420 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3421 consistently agrees with format(x, '.2f').
3422
Benjamin Petersonae937c02009-04-18 20:54:08 +00003423- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00003426- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3427
Eric Smith35e84722009-04-16 20:21:28 +00003428- Issue #5515: str.format() type 'n' combined with commas and leading
3429 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003430
3431- Implement PEP 378, Format Specifier for Thousands Separator, for
3432 floats.
3433
Mark Dickinson3370cce2009-04-17 22:40:53 +00003434- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003435 1e11, not 1e12. This avoids printing 13 significant digits in
3436 situations where only 12 of them are correct. Example problem
3437 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3438 long time.)
3439
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003440- Issue #1580: On most platforms, use a 'short' float repr: for a
3441 finite float x, repr(x) now outputs a string based on the shortest
3442 sequence of decimal digits that rounds to x. Previous behaviour was
3443 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003444 Another minor difference is that the new repr switches to
3445 exponential notation at 1e16 instead of the previous 1e17; this
3446 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003447
3448 There's a new sys attribute sys.float_repr_style, which takes
3449 the value 'short' to indicate that we're using short float repr,
3450 and 'legacy' if the short float repr isn't available for one
3451 reason or another.
3452
3453 The float repr change involves incorporating David Gay's 'perfect
3454 rounding' code into the Python core (it's in Python/dtoa.c). As a
3455 secondary consequence, all string-to-float and float-to-string
3456 conversions (including all float formatting operations) will be
3457 correctly rounded on these platforms.
3458
Georg Brandl5f90d792010-08-01 22:31:05 +00003459 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003460 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003462- Issue #5759: float() didn't call __float__ on str subclasses.
3463
Georg Brandlabc38772009-04-12 15:51:51 +00003464- The string.maketrans() function is deprecated; there is a new static method
3465 maketrans() on the bytes and bytearray classes. This removes confusion about
3466 the types string.maketrans() is supposed to work with, and mirrors the
3467 methods available on the str class.

3759 rotating the object pointer by 4 bits to the right.
3760
Mark Dickinson87ec0852009-02-09 17:15:59 +00003761- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
3762 it now forces its argument to double before testing for infinity.
3763
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00003764- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
3765 returns a non-number type.
3766
Benjamin Peterson87618552009-02-08 15:00:52 +00003767- Issue #5182: Removed memoryview.__str__.
3768
Mark Dickinsonc008a172009-02-01 13:59:22 +00003769- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00003773
Georg Brandl1cdd83c2009-04-05 20:24:29 +00003774- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00003775 were suppressing all exceptions. These include list() and bytearray().
3776
Mark Dickinson1124e712009-01-28 21:25:58 +00003777- Issue #4707: round(x, n) now returns an integer if x is an integer.
3778 Previously it returned a float.
3779
Antoine Pitroub52ec782009-01-25 16:34:23 +00003780- Issue #4753: By enabling a configure option named '--with-computed-gotos'
3781 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3782 evaluation loop is compiled with a new dispatch mechanism which gives
3783 speedups of up to 20%, depending on the system, on various benchmarks.
3784
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00003785- Issue #4874: Most builtin decoders now reject unicode input.

3793 optional module state data.
3794
Mark Dickinson8055afd2009-01-17 10:04:45 +00003795- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003796 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00003797
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003798- Issue #4935: The overflow checking code in the expandtabs() method common
3799 to str, bytes and bytearray could be optimized away by the compiler, letting
3800 the interpreter segfault instead of raising an error.
3801
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003802- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3803 __next__ method.
3804
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003805- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3806 function no longer attempt to call the __long__ slot to convert an object
3807 to an integer. Only the __int__ and __trunc__ slots are examined.
3808
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00003809- Issue #4893: Use NT threading on CE.
3810

3812
Antoine Pitrouab868312009-01-10 15:40:25 +00003813- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3814 common cases are optimized thanks to a dedicated fast path and a moderate
3815 amount of loop unrolling.
3816
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003817- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3818 collecting the oldest generation) so that allocating lots of objects without
3819 destroying them does not show quadratic performance. Based on a proposal by
3820 Martin von Löwis at
3821 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3822
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003823- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003824 having been closed (for instance, a read() call could return some
3825 previously buffered data). Patch by Dmitry Vasiliev.
3826
Antoine Pitrou05608432009-01-09 18:53:14 +00003827- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3828 flag to work properly. Furthermore, when specifying -u, the text stdout
3829 and stderr streams have line-by-line buffering enabled (the default being
3830 to buffer arbitrary chunks of data).
3831
Raymond Hettinger35631532009-01-09 03:58:09 +00003832- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3833 instead of ints (reducing its size from 4 to 8 times thereby reducing
3834 Python's overall memory).
3835
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003836- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3837 an existing .py counterpart, override the co_filename attributes of all
3838 code objects if the original filename is obsolete (which can happen if the
3839 file has been renamed, moved, or if it is accessed through different paths).
3840 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3841
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003842- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3843 one byte. Also fixes the meaning of len() so that it returns the number of
3844 items, rather than the size in bytes.
3845
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003846- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3847
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003848- Issue #4747: When the terminal does not use utf-8, executing a script with
3849 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3850
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003851- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
3852 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00003853
Antoine Pitrou7ddda782009-01-01 15:35:33 +00003854- Issue #3680: Reference cycles created through a dict, set or deque iterator
3855 did not get collected.
3856
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003857- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3858 where the tp_hash and tp_dict slots are both NULL.
3859
Georg Brandlccc47b62008-12-28 11:44:14 +00003860- Issue #4759: None is now allowed as the first argument of
3861 bytearray.translate(). It was always allowed for bytes.translate().
3862
Skip Montanaro80072cb2008-12-23 03:51:14 +00003863- Added test case to ensure attempts to read from a file opened for writing
3864 fail.
3865
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00003866- Issue #3106: Speedup some comparisons (str/str and int/int).

3869 comprehensions. Original patch for list comprehensions by Neal Norwitz.
3870
Antoine Pitrou621601a2008-12-17 23:18:19 +00003871- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
3872 print elapsed times, not only when some objects are uncollectable /
3873 unreachable. Original patch by Neil Schemenauer.
3874
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00003875- Issue #3439: Add a bit_length method to int.
3876
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003877- Issue #2173: When getting device encoding, check that return value of
3878 nl_langinfo is not the empty string. This was causing silent build
3879 failures on OS X.
3880
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003881- Issue #4597: Fixed several opcodes that weren't always propagating
3882 exceptions.
3883
3884- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003885 context manager returns a value that cannot be converted to a bool.
3886
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003887- Issue #4445: Replace "sizeof(PyBytesObject)" with
3888 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3889 bytes instances. On a typical machine this saves 3 bytes of memory
3890 (on average) per allocation of a bytes instance.
3891
Christian Heimesa872de52008-12-05 08:26:55 +00003892- Issue #4533: File read operation was dreadfully slow due to a slowly
3893 growing read buffer. Fixed by using the same growth rate algorithm as
3894 Python 2.x.
3895
Antoine Pitrou5504e892008-12-06 21:27:53 +00003896- Issue #4509: Various issues surrounding resize of bytearray objects to
3897 which there are buffer exports (e.g. memoryview instances).
3898
Georg Brandlf9734072008-12-07 15:30:06 +00003899- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3900 method on file objects with closefd=False. The file descriptor is still
3901 kept open but the file object behaves like a closed file. The ``FileIO``
3902 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003903
Antoine Pitroubc420402008-12-07 20:14:49 +00003904- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00003911- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3912 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3913 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3914 of using the replace error handler in PyUnicode_DecodeUTF8().
