Ned Deily657b2de2011-06-28 19:51:30 -0700365- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
366 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
367 interpreter process. This could cause failures in non-Distutils subprocesses
368 and was unreliable since tests or user programs could modify the interpreter
369 environment after Distutils set it. Instead, have Distutils set the the
370 deployment target only in the environment of each build subprocess. It is
371 still possible to globally override the default by setting
372 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
373 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700374 was built. Also, implement the same handling in packaging.

Steven Bethardb0270112011-01-24 21:02:50 +00001422
1423- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00001424 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001425 that for incoming headers which makes this behaviour now consistent in
1426 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001522- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001523 continuation line in the formatted value has no leading white space and looks
1524 like a header. Since Generator uses Header to format all headers, this check
1525 is made for all headers in any serialized message at serialization time. This
1526 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001527

Éric Araujof0ab5d62011-05-29 03:43:59 +02001535 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001536 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001537
Éric Araujof0ab5d62011-05-29 03:43:59 +02001538- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001539 rfc2047-encoding header values with embedded newlines, leaving them without
1540 folding whitespace. It now uses the continuation_ws, as it does for
1541 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001543- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1544 time.asctime(), time.ctime() and time.strftime() functions will now format

1546 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1547 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1548 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002527- Issue #10068: Global objects which have reference cycles with their module's
2528 dict are now cleared again. This causes issue #7140 to appear again.
2529
Victor Stinner257d38f2010-10-09 10:12:11 +00002530- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002533- ast.literal_eval() can now handle negative numbers. It is also a little more
2534 liberal in what it accepts without compromising the safety of the evaluation.
2535 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00002542- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002543 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002557- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002558 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002562- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2563 threads are still running. Instead, reinitialize the GIL on a second call to
2564 Py_Initialize().
2565
Georg Brandl27a28582010-10-10 09:49:21 +00002566- All SyntaxErrors now have a column offset and therefore a caret when the error
2567 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002568
Brett Cannonbc2eff32010-09-19 21:39:02 +00002569- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2570 module that was imported, but instead gets the module from sys.modules.
2571
Nick Coghlan37ee8502010-12-03 14:26:13 +00002572- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002575- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2576 with a non-empty format string. This is an effort to future-proof user
2577 code. If a derived class does not currently implement __format__ but later
2578 adds its own __format__, it would most likely break user code that had
2579 supplied a format string. This will be changed to a DeprecationWaring in
2580 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002581
Antoine Pitrou1df15362010-09-13 14:16:46 +00002582- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2583 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2584 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2585
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002586- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2587 functions from the libc caused the methods .upper() and lower() to become
2588 locale aware and created subtly wrong results.
2589
Georg Brandl27a28582010-10-10 09:49:21 +00002590- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2591 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002592
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002593- Issue #4617: Previously it was illegal to delete a name from the local
2594 namespace if it occurs as a free variable in a nested block. This limitation
2595 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2596
Georg Brandl27a28582010-10-10 09:49:21 +00002597- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2598 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2599 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2600 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002601
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002602- Issue #9757: memoryview objects get a release() method to release the
2603 underlying buffer (previously this was only done when deallocating the
2604 memoryview), and gain support for the context management protocol.
2605
Antoine Pitrou079ce542010-09-08 12:37:10 +00002606- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2607 thread-local storage key.

2634
Éric Araujoef777bd2010-10-05 00:04:20 +00002635- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002636 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002637 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002638 replacement for old handle_accept() and avoids the user to call accept()
2639 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002663 retry the select() loop instead of bailing out. This is because select() can
2664 incorrectly report a socket as ready for reading (for example, if it received
2665 some data with an invalid checksum).

Antoine Pitrou98b46702010-09-18 22:59:00 +00002711- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002712 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002745- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002746 it possible for the user to create self-referencing ordered dictionaries which
2747 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002748 approach of using weakref proxies so that reference cycles never get created
2749 in the first place.

2757 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2758 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002759

Georg Brandl27a28582010-10-10 09:49:21 +00002770- Issue #9707: Rewritten reference implementation of threading.local which is
2771 friendlier towards reference cycles. This change is not normally visible

Antoine Pitrou783eea72010-09-07 22:06:17 +00002773
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002774- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2775 still return the id of the parent process after it has exited. This process
2776 id may even have been reused by another unrelated process.
2777
Georg Brandl27a28582010-10-10 09:49:21 +00002778- Issue #9792: In case of connection failure, socket.create_connection() would
2779 swallow the exception and raise a new one, making it impossible to fetch the
2780 original errno, or to filter timeout errors. Now the original error is
2781 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002782
Georg Brandl27a28582010-10-10 09:49:21 +00002783- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2784 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2785 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002786
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002787- Updates to the random module:
2788
Georg Brandl27a28582010-10-10 09:49:21 +00002789 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00002792 * Update the seed() method to use all of the bits in a string instead of just
2793 the hash value. This makes better use of the seed value and assures the
2794 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002796 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2797 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2798 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002799
2800 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002819- hashlib has two new constant attributes: algorithms_guaranteed and
2820 algorithms_avaiable that respectively list the names of hash algorithms
2821 guaranteed to exist in all Python implementations and the names of hash
2822 algorithms available in the current process.
2823

Ezio Melotti57221d02010-07-01 07:32:02 +00003334- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003335 start byte and the continuation byte(s) are now considered invalid, instead of
3336 the number of bytes specified by the start byte. E.g.:
3337 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3338 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3339 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3340 returned a single u'\ufffd'.

3384 TypeError instead of giving a DeprecationWarning when a float is parsed using
3385 the 'L' code (for long long). (All other integer codes already raise

3747 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3748 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003749 to match the behaviour of the other integer format codes.

3778 gives improved memory leak detection when running under Valgrind, while taking
3779 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003852- The default size of the re module's compiled regular expression cache has been
3853 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003854 simply clearing the entire cache on overflow to forgetting the least recently
3855 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003856 applications that use a lot of regular expressions and limits the impact of
3857 the performance hit anytime the cache is exceeded.

3870 module is renamed to `_datetime` and if available, overrides all classes
3871 defined in datetime with fast C impementation. Python implementation is based
3872 on the original python prototype for the datetime module by Tim Peters with
3873 minor modifications by the PyPy project. The test suite now tests `datetime`
3874 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004111- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4112 operation raises multiple signals and more than one of those signals is
4113 trapped, the specification determines the order in which the signals should be
4114 handled. In many cases this order wasn't being followed, leading to the wrong

4155 socket wasn't retained (instead, a socket with a positive timeout would be
4156 turned into a non-blocking SSL socket).

Georg Brandl62069d32010-07-31 08:56:11 +00004271- Issue #2531: Comparison operations between floats and Decimal instances now
4272 return a result based on the numeric values of the operands; previously they
4273 returned an arbitrary result based on the relative ordering of id(float) and

Georg Brandl62069d32010-07-31 08:56:11 +00004618 default when instantiating a `threading.RLock` object. This makes recursive
4619 locks as fast as regular non-recursive locks (previously, they were slower by
4620 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00004773 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4774 PyPycLoader inherit from this class and provide implementations in relation to
4775 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004776
Brett Cannon64ef00f2009-07-20 03:19:18 +00004777- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4778 the documentation said it did even though the code in PyLoader relied on the
4779 abstract method required by ResourceLoader.

4833
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004834- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004835 compared to other unix systems. In particular, os.getgroups() does not reflect
4836 any changes made using os.setgroups() but basicly always returns the same
4837 information as the id command. os.getgroups() can now return more than 16
4838 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004839

Georg Brandl62069d32010-07-31 08:56:11 +00004863- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4864 Prior to this change, timezone adjustment in utctimetuple() could produce
4865 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4866 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004868- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4869 directive. When the ``%z`` directive is present in the format string, an
4870 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4871 ``datetime.timezone`` instance constructed from the parsed offset. If both
4872 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4873 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004874
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004875- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004876 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4877 ``datetime.timezone``, return fixed name and UTC offset from their
4878 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4879 returns ``None``. A class attribute, ``utc`` contains an instance
4880 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004896- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4897 with an improved 'binary-split' algorithm that uses fewer multiplications and
4898 allows many of the multiplications to be performed using plain C integer
4899 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004905- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4906 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004907 the result is now always correctly rounded, and is equivalent to ``td /
4908 timedelta(seconds=1)``.

4917 integer format code, struct.pack first attempts to convert the non-integer
4918 using its __index__ method. If that method is non-existent or raises
4919 TypeError it goes on to try the __int__ method, as described below.

5500 default precision of 12. Previously, the behavior the same but with
5501 a default precision of 6. This more closely matches str(), and
5502 reduces surprises when adding alignment flags to the empty
5503 presentation type. This also affects the new complex.__format__ in
5504 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005547- Issue #1869 (and many duplicates): make round(x, n) correctly
5548 rounded for a float x, by using the decimal <-> binary conversions
5549 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5550 consistently agrees with format(x, '.2f').
5551
Benjamin Petersonae937c02009-04-18 20:54:08 +00005552- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5558 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005559
5560- Implement PEP 378, Format Specifier for Thousands Separator, for
5561 floats.
5562
Mark Dickinson3370cce2009-04-17 22:40:53 +00005563- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005564 1e11, not 1e12. This avoids printing 13 significant digits in
5565 situations where only 12 of them are correct. Example problem
5566 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5567 long time.)
5568
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005569- Issue #1580: On most platforms, use a 'short' float repr: for a
5570 finite float x, repr(x) now outputs a string based on the shortest
5571 sequence of decimal digits that rounds to x. Previous behaviour was
5572 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005573 Another minor difference is that the new repr switches to
5574 exponential notation at 1e16 instead of the previous 1e17; this
5575 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005576
5577 There's a new sys attribute sys.float_repr_style, which takes
5578 the value 'short' to indicate that we're using short float repr,
5579 and 'legacy' if the short float repr isn't available for one
5580 reason or another.
5581
5582 The float repr change involves incorporating David Gay's 'perfect
5583 rounding' code into the Python core (it's in Python/dtoa.c). As a
5584 secondary consequence, all string-to-float and float-to-string
5585 conversions (including all float formatting operations) will be
5586 correctly rounded on these platforms.
5587
Georg Brandl5f90d792010-08-01 22:31:05 +00005588 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005589 this change does not apply.

5592
Georg Brandlabc38772009-04-12 15:51:51 +00005593- The string.maketrans() function is deprecated; there is a new static method
5594 maketrans() on the bytes and bytearray classes. This removes confusion about
5595 the types string.maketrans() is supposed to work with, and mirrors the
5596 methods available on the str class.

5832 (typically /dev/zero under Unix) could crash the interpreter.
5833
Benjamin Peterson59406a92009-03-26 17:10:29 +00005834- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

5836
Lars Gustäbel42e00912009-03-22 20:34:29 +00005837- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5838 forever on incomplete input. That caused tarfile.open() to hang when used
5839 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5840 partial bzip2 compressed data.
5841
Mark Dickinson79f52032009-03-17 23:12:51 +00005842- Issue #2110: Add support for thousands separator and 'n' type

5846 '>' alignment characters.
5847
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005848- The error detection code in FileIO.close() could fail to reflect the `errno`
5849 value, and report it as -1 instead.
5850

Mark Dickinsonae681df2009-03-21 10:26:31 +00005859- Issue #5463: In struct module, remove deprecated overflow wrapping
5860 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005861 struct.error instead of returning b'\xff\xff\xff\xff'. The
5862 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5863 have been removed from the struct module.

5879 used when using str.format() with str, int, and float arguments.
5880
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005881- Issue #5249: time.strftime returned malformed string when format string
5882 contained non ascii character on windows.
5883
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005884- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5885 source has already been decoded into str.
5886
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005887- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5888 rotating the object pointer by 4 bits to the right.
5889
Mark Dickinson87ec0852009-02-09 17:15:59 +00005890- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5891 it now forces its argument to double before testing for infinity.
5892
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005893- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5894 returns a non-number type.
5895
Benjamin Peterson87618552009-02-08 15:00:52 +00005896- Issue #5182: Removed memoryview.__str__.
5897
Mark Dickinsonc008a172009-02-01 13:59:22 +00005898- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5899 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005900 the type definition cmpfunc. The tp_compare slot has been renamed
5901 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005902
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005903- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005904 were suppressing all exceptions. These include list() and bytearray().
5905
Mark Dickinson1124e712009-01-28 21:25:58 +00005906- Issue #4707: round(x, n) now returns an integer if x is an integer.
5907 Previously it returned a float.
5908
Antoine Pitroub52ec782009-01-25 16:34:23 +00005909- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5910 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5911 evaluation loop is compiled with a new dispatch mechanism which gives
5912 speedups of up to 20%, depending on the system, on various benchmarks.
5913
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005914- Issue #4874: Most builtin decoders now reject unicode input.

5920
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005921- Issue #4838: When a module is deallocated, free the memory backing the
5922 optional module state data.
5923
Mark Dickinson8055afd2009-01-17 10:04:45 +00005924- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005925 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005926
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005927- Issue #4935: The overflow checking code in the expandtabs() method common
5928 to str, bytes and bytearray could be optimized away by the compiler, letting
5929 the interpreter segfault instead of raising an error.
5930
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005931- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5932 __next__ method.
5933
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005934- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5935 function no longer attempt to call the __long__ slot to convert an object
5936 to an integer. Only the __int__ and __trunc__ slots are examined.
5937
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005938- Issue #4893: Use NT threading on CE.
5939
Martin v. Löwisec59d042009-01-12 07:59:10 +00005940- Issue #4915: Port sysmodule to Windows CE.
5941
Antoine Pitrouab868312009-01-10 15:40:25 +00005942- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5943 common cases are optimized thanks to a dedicated fast path and a moderate
5944 amount of loop unrolling.
5945
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005946- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5947 collecting the oldest generation) so that allocating lots of objects without
5948 destroying them does not show quadratic performance. Based on a proposal by
5949 Martin von Löwis at
5950 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5951
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005952- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005953 having been closed (for instance, a read() call could return some
5954 previously buffered data). Patch by Dmitry Vasiliev.
5955
Antoine Pitrou05608432009-01-09 18:53:14 +00005956- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5957 flag to work properly. Furthermore, when specifying -u, the text stdout
5958 and stderr streams have line-by-line buffering enabled (the default being
5959 to buffer arbitrary chunks of data).
5960
Raymond Hettinger35631532009-01-09 03:58:09 +00005961- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5962 instead of ints (reducing its size from 4 to 8 times thereby reducing
5963 Python's overall memory).
5964
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005965- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5966 an existing .py counterpart, override the co_filename attributes of all
5967 code objects if the original filename is obsolete (which can happen if the
5968 file has been renamed, moved, or if it is accessed through different paths).
5969 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5970
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005971- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5972 one byte. Also fixes the meaning of len() so that it returns the number of
5973 items, rather than the size in bytes.
5974
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005975- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5976
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005977- Issue #4747: When the terminal does not use utf-8, executing a script with
5978 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5979
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005980- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5981 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005982
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005983- Issue #3680: Reference cycles created through a dict, set or deque iterator
5984 did not get collected.
5985
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005986- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5987 where the tp_hash and tp_dict slots are both NULL.
5988
Georg Brandlccc47b62008-12-28 11:44:14 +00005989- Issue #4759: None is now allowed as the first argument of
5990 bytearray.translate(). It was always allowed for bytes.translate().
5991
Skip Montanaro80072cb2008-12-23 03:51:14 +00005992- Added test case to ensure attempts to read from a file opened for writing
5993 fail.
5994
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005995- Issue #3106: Speedup some comparisons (str/str and int/int).

5999
Antoine Pitrou621601a2008-12-17 23:18:19 +00006000- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6001 print elapsed times, not only when some objects are uncollectable /
6002 unreachable. Original patch by Neil Schemenauer.
6003
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006004- Issue #3439: Add a bit_length method to int.
6005
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006006- Issue #2173: When getting device encoding, check that return value of
6007 nl_langinfo is not the empty string. This was causing silent build
6008 failures on OS X.
6009
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006010- Issue #4597: Fixed several opcodes that weren't always propagating
6011 exceptions.
6012
6013- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006014 context manager returns a value that cannot be converted to a bool.
6015
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006016- Issue #4445: Replace "sizeof(PyBytesObject)" with
6017 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6018 bytes instances. On a typical machine this saves 3 bytes of memory
6019 (on average) per allocation of a bytes instance.
6020
Christian Heimesa872de52008-12-05 08:26:55 +00006021- Issue #4533: File read operation was dreadfully slow due to a slowly
6022 growing read buffer. Fixed by using the same growth rate algorithm as
6023 Python 2.x.
6024
Antoine Pitrou5504e892008-12-06 21:27:53 +00006025- Issue #4509: Various issues surrounding resize of bytearray objects to
6026 which there are buffer exports (e.g. memoryview instances).
6027
Georg Brandlf9734072008-12-07 15:30:06 +00006028- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6029 method on file objects with closefd=False. The file descriptor is still
6030 kept open but the file object behaves like a closed file. The ``FileIO``
6031 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006032
Antoine Pitroubc420402008-12-07 20:14:49 +00006033- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6034 larger than 1.

6039
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006040- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6041 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6042 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6043 of using the replace error handler in PyUnicode_DecodeUTF8().
