Ned Deily657b2de2011-06-28 19:51:30 -0700553- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
554 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
555 interpreter process. This could cause failures in non-Distutils subprocesses
556 and was unreliable since tests or user programs could modify the interpreter
557 environment after Distutils set it. Instead, have Distutils set the the
558 deployment target only in the environment of each build subprocess. It is
559 still possible to globally override the default by setting
560 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
561 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700562 was built. Also, implement the same handling in packaging.

1700
Victor Stinnerb3c9e072011-01-04 02:07:34 +00001701- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
1702 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1703 translates newlines (\r\n => \n).
1704
Victor Stinnerdc555402011-01-04 13:15:39 +00001705- Remove buffer API from stable ABI for now, see #10181.
1706
Victor Stinnere6edec22011-01-04 00:29:35 +00001707- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
Amaury Forgeot d'Arca251a852011-01-03 00:19:11 +00001708 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
1709 (length bigger than 2^31-1 bytes).
1710
Victor Stinner92be9392010-12-28 00:28:21 +00001711- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
Victor Stinnerc655a722011-07-05 11:31:49 +02001712 stdprinter.write() clamp the length to INT_MAX on Windows.
Victor Stinner92be9392010-12-28 00:28:21 +00001713
1714- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
Victor Stinnercb428f02010-12-27 20:10:36 +00001715 can now handle dates after 2038.
1716
1717- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
Georg Brandl8aa7e992010-12-28 18:30:18 +00001718 PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
1719 filesystem encoding instead of UTF-8.
Raymond Hettinger8ebe27f2010-12-21 19:24:26 +00001720
1721- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem

1730-------
1731
Georg Brandl255abdd2011-01-16 14:17:26 +00001732- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
1733 and a non-zero offset, and an attempt to read past the end of file is made
1734 (IndexError is raised instead). Patch by Ross Lagerwall.
Antoine Pitrou85f46152011-01-15 16:17:07 +00001735
Ronald Oussoren6edd8c12011-05-17 13:03:54 +02001736- Issue #10154, #10090: change the normalization of UTF-8 to "UTF-8" instead
1737 of "UTF8" in the locale module as the latter is not supported MacOSX and OpenBSD.
1738
Georg Brandl255abdd2011-01-16 14:17:26 +00001739- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
1740 than the currently problematic Apple-supplied one, when running with the
1741 64-/32-bit installer variant.
Ned Deily4ce92b22011-01-15 04:37:12 +00001742
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001743- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
1744 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +00001745 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
1746 Linderman).
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001747
Georg Brandl255abdd2011-01-16 14:17:26 +00001748- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().

Georg Brandl619e7ba2011-01-09 07:38:51 +00001760
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001761- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001762 continuation line in the formatted value has no leading white space and looks
1763 like a header. Since Generator uses Header to format all headers, this check
1764 is made for all headers in any serialized message at serialization time. This
1765 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001766
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001767- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

1772
R. David Murray92532142011-01-07 23:25:30 +00001773- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001774 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001775 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001776
Éric Araujof0ab5d62011-05-29 03:43:59 +02001777- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001778 rfc2047-encoding header values with embedded newlines, leaving them without
1779 folding whitespace. It now uses the continuation_ws, as it does for
1780 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001781
Victor Stinner3ec899f2011-01-08 16:37:47 +00001782- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1783 time.asctime(), time.ctime() and time.strftime() functions will now format
1784 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1785 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1786 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1787 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001788
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001789- Issue #7858: Raise an error properly when os.utime() fails under Windows
1790 on an existing file.
1791
Antoine Pitroub715fac2011-01-06 17:17:04 +00001792- Issue #3839: wsgiref should not override a Content-Length header set by

1794
Victor Stinner4bd81722011-01-06 00:49:38 +00001795- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1796 compilation (if the input is a string).
1797
Antoine Pitrou600232b2011-01-05 21:03:42 +00001798- Issue #7995: When calling accept() on a socket with a timeout, the returned

Victor Stinnerc3a51ec2011-01-04 11:00:45 +00001807- Issue #10819: SocketIO.name property returns -1 when its closed, instead of

1811 the input buffer length doesn't fit into an unsigned int (length bigger than
1812 2^32-1 bytes).
1813
Georg Brandl255abdd2011-01-16 14:17:26 +00001814- Issue #6643: Reinitialize locks held within the threading module after fork to

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002421 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2765
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002766- Issue #10068: Global objects which have reference cycles with their module's
2767 dict are now cleared again. This causes issue #7140 to appear again.
2768
Victor Stinner257d38f2010-10-09 10:12:11 +00002769- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002770 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002771
Georg Brandl27a28582010-10-10 09:49:21 +00002772- ast.literal_eval() can now handle negative numbers. It is also a little more
2773 liberal in what it accepts without compromising the safety of the evaluation.
2774 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002775
Benjamin Peterson970d1882010-10-02 17:55:47 +00002776- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2777 result metaclasses can now be ABCs (see #9533).
2778
Victor Stinneraef57e32010-10-02 11:50:49 +00002779- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2780
Victor Stinner5593d8a2010-10-02 11:11:27 +00002781- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002782 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2783 32 bits wchar_t (eg. Linux in narrow build).

Brett Cannon5305a992010-09-27 21:08:38 +00002790- Issue #7397: Mention that importlib.import_module() is probably what someone

2792
Georg Brandl27a28582010-10-10 09:49:21 +00002793- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2794 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002796- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002797 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002799- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2800
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002801- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2802 threads are still running. Instead, reinitialize the GIL on a second call to
2803 Py_Initialize().
2804
Georg Brandl27a28582010-10-10 09:49:21 +00002805- All SyntaxErrors now have a column offset and therefore a caret when the error
2806 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002807
Brett Cannonbc2eff32010-09-19 21:39:02 +00002808- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2809 module that was imported, but instead gets the module from sys.modules.
2810
Nick Coghlan37ee8502010-12-03 14:26:13 +00002811- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002812 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002813
Georg Brandl27a28582010-10-10 09:49:21 +00002814- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2815 with a non-empty format string. This is an effort to future-proof user
2816 code. If a derived class does not currently implement __format__ but later
2817 adds its own __format__, it would most likely break user code that had
2818 supplied a format string. This will be changed to a DeprecationWaring in
2819 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002820
Antoine Pitrou1df15362010-09-13 14:16:46 +00002821- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2822 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2823 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2824
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002825- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2826 functions from the libc caused the methods .upper() and lower() to become
2827 locale aware and created subtly wrong results.
2828
Georg Brandl27a28582010-10-10 09:49:21 +00002829- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2830 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002831
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002832- Issue #4617: Previously it was illegal to delete a name from the local
2833 namespace if it occurs as a free variable in a nested block. This limitation
2834 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2835
Georg Brandl27a28582010-10-10 09:49:21 +00002836- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2837 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2838 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2839 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002840
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002841- Issue #9757: memoryview objects get a release() method to release the
2842 underlying buffer (previously this was only done when deallocating the
2843 memoryview), and gain support for the context management protocol.
2844
Antoine Pitrou079ce542010-09-08 12:37:10 +00002845- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2846 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002862- Issue #4661: email can now parse bytes input and generate either converted

2864
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002865- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2870
Éric Araujo6108bf52010-10-04 23:52:37 +00002871- Issue #9042: Fix interaction of custom translation classes and caching in
2872 gettext.
2873
Éric Araujoef777bd2010-10-05 00:04:20 +00002874- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002875 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002876 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002877 replacement for old handle_accept() and avoids the user to call accept()
2878 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002901- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002902 retry the select() loop instead of bailing out. This is because select() can
2903 incorrectly report a socket as ready for reading (for example, if it received
2904 some data with an invalid checksum).

2949
Antoine Pitrou98b46702010-09-18 22:59:00 +00002950- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002951 non-blocking mode: they return None when an operation would block (instead of
2952 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002953
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002954- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Antoine Pitrou328ec742010-09-14 18:37:24 +00002963
Georg Brandl27a28582010-10-10 09:49:21 +00002964- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2965 supporting the whole socket API (rather than the "raw" _socket.socket
2966 objects).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002984- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002985 it possible for the user to create self-referencing ordered dictionaries which
2986 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002987 approach of using weakref proxies so that reference cycles never get created
2988 in the first place.
2989
Victor Stinnercb043522010-09-10 23:49:04 +00002990- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2991 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002992 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002993
Georg Brandl27a28582010-10-10 09:49:21 +00002994- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2995 environment variable to set the filesystem encoding at Python startup.
2996 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2997 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002998
Georg Brandl27a28582010-10-10 09:49:21 +00002999- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00003006- Logging: Added QueueHandler class to facilitate logging usage with
3007 multiprocessing.
3008
Georg Brandl27a28582010-10-10 09:49:21 +00003009- Issue #9707: Rewritten reference implementation of threading.local which is
3010 friendlier towards reference cycles. This change is not normally visible
3011 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003012
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003013- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3014 still return the id of the parent process after it has exited. This process
3015 id may even have been reused by another unrelated process.
3016
Georg Brandl27a28582010-10-10 09:49:21 +00003017- Issue #9792: In case of connection failure, socket.create_connection() would
3018 swallow the exception and raise a new one, making it impossible to fetch the
3019 original errno, or to filter timeout errors. Now the original error is
3020 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00003021
Georg Brandl27a28582010-10-10 09:49:21 +00003022- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3023 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3024 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003025
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003026- Updates to the random module:
3027
Georg Brandl27a28582010-10-10 09:49:21 +00003028 * Document which parts of the module are guaranteed to stay the same across
3029 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003031 * Update the seed() method to use all of the bits in a string instead of just
3032 the hash value. This makes better use of the seed value and assures the
3033 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003035 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3036 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3037 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003038
3039 * Improved documentation of arguments to randrange(). Issue #9379.

3045 cases now also have assertWarns and assertWarnsRegexp methods to check that a
3046 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003058- hashlib has two new constant attributes: algorithms_guaranteed and
3059 algorithms_avaiable that respectively list the names of hash algorithms
3060 guaranteed to exist in all Python implementations and the names of hash
3061 algorithms available in the current process.
3062

Ezio Melotti57221d02010-07-01 07:32:02 +00003573- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003574 start byte and the continuation byte(s) are now considered invalid, instead of
3575 the number of bytes specified by the start byte. E.g.:
3576 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3577 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3578 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3579 returned a single u'\ufffd'.

3608
Georg Brandl62069d32010-07-31 08:56:11 +00003609- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003610 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003622- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3623 TypeError instead of giving a DeprecationWarning when a float is parsed using
3624 the 'L' code (for long long). (All other integer codes already raise
3625 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003626

3629 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3630
Georg Brandl62069d32010-07-31 08:56:11 +00003631- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Georg Brandl62069d32010-07-31 08:56:11 +00003635 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003636 like bytearray.
3637
Georg Brandl62069d32010-07-31 08:56:11 +00003638- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003651- Issue #8748: Fix two issues with comparisons between complex and integer
3652 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003653 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3654 (2) The comparison raised an OverflowError for large integers, leading to
3655 unpredictable exceptions when combining integers and complex objects in sets
3656 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003958- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

3960 `va_copy`, but available on all python platforms.
3961
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003962- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3963 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3964 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003974- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003975 function declaration, which was kept for backwards compatibility reasons, is
3976 now removed (the macro was introduced in 1997!).

3986 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3987 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003988 to match the behaviour of the other integer format codes.
3989

Georg Brandl62069d32010-07-31 08:56:11 +00003998- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3999 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4000 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00004015- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4016 allocator will be automatically disabled when running under Valgrind. This
4017 gives improved memory leak detection when running under Valgrind, while taking
4018 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004095 applications that use a lot of regular expressions and limits the impact of
4096 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004108- Issue #7989: Added pure python implementation of the `datetime` module. The C
4109 module is renamed to `_datetime` and if available, overrides all classes
4110 defined in datetime with fast C impementation. Python implementation is based
4111 on the original python prototype for the datetime module by Tim Peters with
4112 minor modifications by the PyPy project. The test suite now tests `datetime`
4113 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004334- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
4335 messages when accessing undefined class attributes because of the cheap
4336 inheritance with the underlying socket object. The cheap inheritance has been
4337 deprecated.

Georg Brandl62069d32010-07-31 08:56:11 +00004350- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4351 operation raises multiple signals and more than one of those signals is
4352 trapped, the specification determines the order in which the signals should be
4353 handled. In many cases this order wasn't being followed, leading to the wrong
4354 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004393- Issue #8524: When creating an SSL socket, the timeout value of the original
4394 socket wasn't retained (instead, a socket with a positive timeout would be
4395 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004396
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004397- Issue #5103: SSL handshake would ignore the socket timeout and block
4398 indefinitely if the other end didn't respond.
4399
Georg Brandl62069d32010-07-31 08:56:11 +00004400- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004416- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4417 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004418 wanting to continue using the socket in clear-text mode, by disabling

Georg Brandl62069d32010-07-31 08:56:11 +00004510- Issue #2531: Comparison operations between floats and Decimal instances now
4511 return a result based on the numeric values of the operands; previously they
4512 returned an arbitrary result based on the relative ordering of id(float) and
4513 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4514 comparisons.

4529 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4530 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004577- subprocess.Popen now has restore_signals and start_new_session features. The
4578 default of restore_signals=True is a new behavior compared to earlier Python
4579 versions. This means that signals such as SIGPIPE are not ignored by default
4580 in subprocesses launched by Python (Issue #1652).

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005073- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005074 compared to other unix systems. In particular, os.getgroups() does not reflect
5075 any changes made using os.setgroups() but basicly always returns the same
5076 information as the id command. os.getgroups() can now return more than 16
5077 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005102- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5103 Prior to this change, timezone adjustment in utctimetuple() could produce
5104 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5105 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005107- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5108 directive. When the ``%z`` directive is present in the format string, an
5109 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5110 ``datetime.timezone`` instance constructed from the parsed offset. If both
5111 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5112 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005113
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005114- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005115 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5116 ``datetime.timezone``, return fixed name and UTC offset from their
5117 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5118 returns ``None``. A class attribute, ``utc`` contains an instance
5119 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005135- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5136 with an improved 'binary-split' algorithm that uses fewer multiplications and
5137 allows many of the multiplications to be performed using plain C integer
5138 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5139 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005144- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5145 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005146 the result is now always correctly rounded, and is equivalent to ``td /
5147 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00005155- Issue #8300: When passing a non-integer argument to struct.pack with any
5156 integer format code, struct.pack first attempts to convert the non-integer
5157 using its __index__ method. If that method is non-existent or raises
5158 TypeError it goes on to try the __int__ method, as described below.

5609 and imaginary literals.
5610
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005611- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

5616 (1) inf and nan strings with trailing whitespace were incorrectly
5617 rejected; (2) parsing of strings representing infinities and nans
5618 was locale aware; and (3) the interpretation of fromhex('-nan')

5636
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005637- In unittest, using a skipping decorator on a class is now equivalent to

5642
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005643- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5644 than an int, which makes some operations possible under 64-bit Linux (e.g.
5645 DN_MULTISHOT with F_NOTIFY).
5646
Antoine Pitrou716c4442009-05-23 19:04:03 +00005647- Issue #5761: Add the name of the underlying file to the repr() of various

5668
Antoine Pitroue4501852009-05-14 18:55:55 +00005669- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5670 library. This means, for example, that opening an UTF-16 text file in
5671 append mode doesn't add a BOM at the end of the file if the file isn't
5672 empty.

Mark Dickinson865e01a2009-05-07 16:37:01 +00005725- Issue #5914: Add new C API function PyOS_string_to_double, and
5726 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5727
Eric Smith741191f2009-05-06 13:08:15 +00005728- Issue #3382: float.__format__, complex.__format__, and %-formatting
5729 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5730 affects nan -> NAN and inf -> INF.
5731
Mark Hammond5a607a32009-05-06 08:04:54 +00005732- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5733 in all operations, including splitdrive, split, etc. splitunc() now issues
5734 a PendingDeprecation warning.
5735
Eric Smith63376222009-05-05 14:04:18 +00005736- Issue #5920: For float.__format__, change the behavior with the
5737 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5738 to be like 'g' but with at least one decimal point and with a
5739 default precision of 12. Previously, the behavior the same but with
5740 a default precision of 6. This more closely matches str(), and
5741 reduces surprises when adding alignment flags to the empty
5742 presentation type. This also affects the new complex.__format__ in
5743 the same way.
5744
Martin v. Löwis011e8422009-05-05 04:43:17 +00005745- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5746
R. David Murrayb18500d2009-05-04 22:59:07 +00005747- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5748 shadowed by classtype's, even if it was None. property now
5749 inserts the __doc__ into the subclass instance __dict__.
5750
Antoine Pitrou244651a2009-05-04 18:56:13 +00005751- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5752 sequences. Patch by Nick Barnes and Victor Stinner.
5753
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005754- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005755
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005756- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5757 received a new method, detach(). detach() disconnects the underlying stream
5758 from the buffer or text IO and returns it.
5759
Mark Dickinson33841c32009-05-01 15:37:04 +00005760- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5761 floats with absolute value over 1e50. Also remove length
5762 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5763 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005764
Eric Smith741191f2009-05-06 13:08:15 +00005765- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005766 format(complex(1, 2./3), '.5') now produces a sensible result.
5767
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005768- Issue #5864: Fix empty format code formatting for floats so that it
5769 never gives more than the requested number of significant digits.
5770
Eric Smith6dc46f52009-04-27 20:39:49 +00005771- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5772 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5773
Eric Smithcc32a112009-04-26 21:35:14 +00005774- Issue #5835: Deprecate PyOS_ascii_formatd.
5775
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005776- Issue #4971: Fix titlecase for characters that are their own
5777 titlecase, but not their own uppercase.
5778
Benjamin Peterson193152c2009-04-25 01:08:45 +00005779- Issue #5283: Setting __class__ in __del__ caused a segfault.
5780
Mark Dickinsonad476da2009-04-23 19:14:16 +00005781- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5782 z involves nans, infs or negative zeros.
5783
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005784- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005785
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005786- Issue #1869 (and many duplicates): make round(x, n) correctly
5787 rounded for a float x, by using the decimal <-> binary conversions
5788 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5789 consistently agrees with format(x, '.2f').
5790
Benjamin Petersonae937c02009-04-18 20:54:08 +00005791- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5792 some builtin types.
5793
Eric Smith0923d1d2009-04-16 20:16:10 +00005794- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5795
Eric Smith35e84722009-04-16 20:21:28 +00005796- Issue #5515: str.format() type 'n' combined with commas and leading
5797 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005798
5799- Implement PEP 378, Format Specifier for Thousands Separator, for
5800 floats.
5801
Mark Dickinson3370cce2009-04-17 22:40:53 +00005802- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005803 1e11, not 1e12. This avoids printing 13 significant digits in
5804 situations where only 12 of them are correct. Example problem
5805 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5806 long time.)

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005808- Issue #1580: On most platforms, use a 'short' float repr: for a
5809 finite float x, repr(x) now outputs a string based on the shortest
5810 sequence of decimal digits that rounds to x. Previous behaviour was
5811 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005812 Another minor difference is that the new repr switches to
5813 exponential notation at 1e16 instead of the previous 1e17; this
5814 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005815
5816 There's a new sys attribute sys.float_repr_style, which takes
5817 the value 'short' to indicate that we're using short float repr,
5818 and 'legacy' if the short float repr isn't available for one
5819 reason or another.
5820
5821 The float repr change involves incorporating David Gay's 'perfect
5822 rounding' code into the Python core (it's in Python/dtoa.c). As a
5823 secondary consequence, all string-to-float and float-to-string
5824 conversions (including all float formatting operations) will be
5825 correctly rounded on these platforms.
5826
Georg Brandl5f90d792010-08-01 22:31:05 +00005827 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005828 this change does not apply.

5831
Georg Brandlabc38772009-04-12 15:51:51 +00005832- The string.maketrans() function is deprecated; there is a new static method
5833 maketrans() on the bytes and bytearray classes. This removes confusion about
5834 the types string.maketrans() is supposed to work with, and mirrors the
5835 methods available on the str class.

6125
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006126- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6127 rotating the object pointer by 4 bits to the right.
6128
Mark Dickinson87ec0852009-02-09 17:15:59 +00006129- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6130 it now forces its argument to double before testing for infinity.
6131
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006132- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

6140 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006141
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006142- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006143 were suppressing all exceptions. These include list() and bytearray().

6147
Antoine Pitroub52ec782009-01-25 16:34:23 +00006148- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6149 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6150 evaluation loop is compiled with a new dispatch mechanism which gives
6151 speedups of up to 20%, depending on the system, on various benchmarks.
6152
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006153- Issue #4874: Most builtin decoders now reject unicode input.

6159
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006160- Issue #4838: When a module is deallocated, free the memory backing the
6161 optional module state data.
6162
Mark Dickinson8055afd2009-01-17 10:04:45 +00006163- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006164 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006165
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006166- Issue #4935: The overflow checking code in the expandtabs() method common
6167 to str, bytes and bytearray could be optimized away by the compiler, letting
6168 the interpreter segfault instead of raising an error.
6169
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006170- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6171 __next__ method.
6172
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006173- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6174 function no longer attempt to call the __long__ slot to convert an object
6175 to an integer. Only the __int__ and __trunc__ slots are examined.
6176
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006177- Issue #4893: Use NT threading on CE.
6178

6180
Antoine Pitrouab868312009-01-10 15:40:25 +00006181- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6182 common cases are optimized thanks to a dedicated fast path and a moderate
6183 amount of loop unrolling.
6184
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006185- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6186 collecting the oldest generation) so that allocating lots of objects without
6187 destroying them does not show quadratic performance. Based on a proposal by
6188 Martin von Löwis at
6189 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6190
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006191- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006192 having been closed (for instance, a read() call could return some
6193 previously buffered data). Patch by Dmitry Vasiliev.
6194
Antoine Pitrou05608432009-01-09 18:53:14 +00006195- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6196 flag to work properly. Furthermore, when specifying -u, the text stdout
6197 and stderr streams have line-by-line buffering enabled (the default being
6198 to buffer arbitrary chunks of data).
6199
Raymond Hettinger35631532009-01-09 03:58:09 +00006200- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6201 instead of ints (reducing its size from 4 to 8 times thereby reducing
6202 Python's overall memory).
6203
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006204- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6205 an existing .py counterpart, override the co_filename attributes of all
6206 code objects if the original filename is obsolete (which can happen if the
6207 file has been renamed, moved, or if it is accessed through different paths).
6208 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6209
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006210- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6211 one byte. Also fixes the meaning of len() so that it returns the number of
6212 items, rather than the size in bytes.
6213
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006214- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6215
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006216- Issue #4747: When the terminal does not use utf-8, executing a script with
6217 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6218
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006219- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6220 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006221
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006222- Issue #3680: Reference cycles created through a dict, set or deque iterator
6223 did not get collected.
6224
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006225- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6226 where the tp_hash and tp_dict slots are both NULL.
6227
Georg Brandlccc47b62008-12-28 11:44:14 +00006228- Issue #4759: None is now allowed as the first argument of
6229 bytearray.translate(). It was always allowed for bytes.translate().
6230
Skip Montanaro80072cb2008-12-23 03:51:14 +00006231- Added test case to ensure attempts to read from a file opened for writing
6232 fail.
6233
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006234- Issue #3106: Speedup some comparisons (str/str and int/int).

6238
Antoine Pitrou621601a2008-12-17 23:18:19 +00006239- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6240 print elapsed times, not only when some objects are uncollectable /
6241 unreachable. Original patch by Neil Schemenauer.
6242
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006243- Issue #3439: Add a bit_length method to int.
6244
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006245- Issue #2173: When getting device encoding, check that return value of
6246 nl_langinfo is not the empty string. This was causing silent build
6247 failures on OS X.
6248
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006249- Issue #4597: Fixed several opcodes that weren't always propagating
6250 exceptions.
6251
6252- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006253 context manager returns a value that cannot be converted to a bool.
6254
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006255- Issue #4445: Replace "sizeof(PyBytesObject)" with
6256 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6257 bytes instances. On a typical machine this saves 3 bytes of memory
6258 (on average) per allocation of a bytes instance.
6259
Christian Heimesa872de52008-12-05 08:26:55 +00006260- Issue #4533: File read operation was dreadfully slow due to a slowly
6261 growing read buffer. Fixed by using the same growth rate algorithm as
6262 Python 2.x.
6263
Antoine Pitrou5504e892008-12-06 21:27:53 +00006264- Issue #4509: Various issues surrounding resize of bytearray objects to
6265 which there are buffer exports (e.g. memoryview instances).
6266
Georg Brandlf9734072008-12-07 15:30:06 +00006267- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6268 method on file objects with closefd=False. The file descriptor is still
6269 kept open but the file object behaves like a closed file. The ``FileIO``
6270 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006271
Antoine Pitroubc420402008-12-07 20:14:49 +00006272- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6273 larger than 1.

6278
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006279- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6280 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6281 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6282 of using the replace error handler in PyUnicode_DecodeUTF8().
