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.

1705 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1706 translates newlines (\r\n => \n).
1707
Victor Stinnerdc555402011-01-04 13:15:39 +00001708- Remove buffer API from stable ABI for now, see #10181.

1713
Victor Stinner92be9392010-12-28 00:28:21 +00001714- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
Victor Stinnerc655a722011-07-05 11:31:49 +02001715 stdprinter.write() clamp the length to INT_MAX on Windows.
Victor Stinner92be9392010-12-28 00:28:21 +00001716
1717- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()

Georg Brandl8aa7e992010-12-28 18:30:18 +00001721 PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
1722 filesystem encoding instead of UTF-8.

1733-------
1734
Georg Brandl255abdd2011-01-16 14:17:26 +00001735- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
1736 and a non-zero offset, and an attempt to read past the end of file is made
1737 (IndexError is raised instead). Patch by Ross Lagerwall.
Antoine Pitrou85f46152011-01-15 16:17:07 +00001738

1741
Georg Brandl255abdd2011-01-16 14:17:26 +00001742- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
1743 than the currently problematic Apple-supplied one, when running with the
1744 64-/32-bit installer variant.
Ned Deily4ce92b22011-01-15 04:37:12 +00001745
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001746- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
1747 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +00001748 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
1749 Linderman).
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001750
Georg Brandl255abdd2011-01-16 14:17:26 +00001751- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().

Georg Brandl619e7ba2011-01-09 07:38:51 +00001763
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001764- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001765 continuation line in the formatted value has no leading white space and looks
1766 like a header. Since Generator uses Header to format all headers, this check
1767 is made for all headers in any serialized message at serialization time. This
1768 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001769
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001770- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +00001776- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001777 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001778 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001779
Éric Araujof0ab5d62011-05-29 03:43:59 +02001780- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001781 rfc2047-encoding header values with embedded newlines, leaving them without
1782 folding whitespace. It now uses the continuation_ws, as it does for
1783 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001784
Victor Stinner3ec899f2011-01-08 16:37:47 +00001785- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1786 time.asctime(), time.ctime() and time.strftime() functions will now format
1787 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1788 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1789 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1790 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001791
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001792- Issue #7858: Raise an error properly when os.utime() fails under Windows

1797
Victor Stinner4bd81722011-01-06 00:49:38 +00001798- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1799 compilation (if the input is a string).
1800
Antoine Pitrou600232b2011-01-05 21:03:42 +00001801- Issue #7995: When calling accept() on a socket with a timeout, the returned

Antoine Pitrou600232b2011-01-05 21:03:42 +00001803
Victor Stinner8786d3d2011-01-05 03:56:22 +00001804- Issue #10756: atexit normalizes the exception before displaying it. Patch by

1814 the input buffer length doesn't fit into an unsigned int (length bigger than
1815 2^32-1 bytes).
1816
Georg Brandl255abdd2011-01-16 14:17:26 +00001817- Issue #6643: Reinitialize locks held within the threading module after fork to

1843 time. `sys.stderr` now looked up at instantiation time. Fix contributed by

2768
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002769- Issue #10068: Global objects which have reference cycles with their module's
2770 dict are now cleared again. This causes issue #7140 to appear again.
2771
Victor Stinner257d38f2010-10-09 10:12:11 +00002772- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002773 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002774
Georg Brandl27a28582010-10-10 09:49:21 +00002775- ast.literal_eval() can now handle negative numbers. It is also a little more
2776 liberal in what it accepts without compromising the safety of the evaluation.
2777 For example, 3j+4 and 3+4+5 are both accepted.

2781
Victor Stinneraef57e32010-10-02 11:50:49 +00002782- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2783
Victor Stinner5593d8a2010-10-02 11:11:27 +00002784- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002785 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2786 32 bits wchar_t (eg. Linux in narrow build).

2792
Brett Cannon5305a992010-09-27 21:08:38 +00002793- Issue #7397: Mention that importlib.import_module() is probably what someone

2795
Georg Brandl27a28582010-10-10 09:49:21 +00002796- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2797 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002799- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002800 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002802- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2803
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002804- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2805 threads are still running. Instead, reinitialize the GIL on a second call to
2806 Py_Initialize().
2807
Georg Brandl27a28582010-10-10 09:49:21 +00002808- All SyntaxErrors now have a column offset and therefore a caret when the error
2809 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002810
Brett Cannonbc2eff32010-09-19 21:39:02 +00002811- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2812 module that was imported, but instead gets the module from sys.modules.
2813
Nick Coghlan37ee8502010-12-03 14:26:13 +00002814- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002815 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002816
Georg Brandl27a28582010-10-10 09:49:21 +00002817- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2818 with a non-empty format string. This is an effort to future-proof user
2819 code. If a derived class does not currently implement __format__ but later
2820 adds its own __format__, it would most likely break user code that had
2821 supplied a format string. This will be changed to a DeprecationWaring in
2822 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002823
Antoine Pitrou1df15362010-09-13 14:16:46 +00002824- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2825 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2826 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2827
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002828- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2829 functions from the libc caused the methods .upper() and lower() to become
2830 locale aware and created subtly wrong results.
2831
Georg Brandl27a28582010-10-10 09:49:21 +00002832- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2833 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002834
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002835- Issue #4617: Previously it was illegal to delete a name from the local
2836 namespace if it occurs as a free variable in a nested block. This limitation
2837 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2838
Georg Brandl27a28582010-10-10 09:49:21 +00002839- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2840 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2841 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2842 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002843
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002844- Issue #9757: memoryview objects get a release() method to release the
2845 underlying buffer (previously this was only done when deallocating the
2846 memoryview), and gain support for the context management protocol.
2847
Antoine Pitrou079ce542010-09-08 12:37:10 +00002848- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2849 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002865- Issue #4661: email can now parse bytes input and generate either converted

2867
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002868- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2873
Éric Araujo6108bf52010-10-04 23:52:37 +00002874- Issue #9042: Fix interaction of custom translation classes and caching in
2875 gettext.
2876
Éric Araujoef777bd2010-10-05 00:04:20 +00002877- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002878 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002879 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002880 replacement for old handle_accept() and avoids the user to call accept()
2881 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002904- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002905 retry the select() loop instead of bailing out. This is because select() can
2906 incorrectly report a socket as ready for reading (for example, if it received
2907 some data with an invalid checksum).

2952
Antoine Pitrou98b46702010-09-18 22:59:00 +00002953- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002954 non-blocking mode: they return None when an operation would block (instead of
2955 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002956
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002957- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

2965 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002966
Georg Brandl27a28582010-10-10 09:49:21 +00002967- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2968 supporting the whole socket API (rather than the "raw" _socket.socket
2969 objects).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002987- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002988 it possible for the user to create self-referencing ordered dictionaries which
2989 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002990 approach of using weakref proxies so that reference cycles never get created
2991 in the first place.
2992
Victor Stinnercb043522010-09-10 23:49:04 +00002993- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2994 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002995 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002996
Georg Brandl27a28582010-10-10 09:49:21 +00002997- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2998 environment variable to set the filesystem encoding at Python startup.
2999 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3000 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003001
Georg Brandl27a28582010-10-10 09:49:21 +00003002- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00003009- Logging: Added QueueHandler class to facilitate logging usage with
3010 multiprocessing.
3011
Georg Brandl27a28582010-10-10 09:49:21 +00003012- Issue #9707: Rewritten reference implementation of threading.local which is
3013 friendlier towards reference cycles. This change is not normally visible
3014 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003015
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003016- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3017 still return the id of the parent process after it has exited. This process
3018 id may even have been reused by another unrelated process.
3019
Georg Brandl27a28582010-10-10 09:49:21 +00003020- Issue #9792: In case of connection failure, socket.create_connection() would
3021 swallow the exception and raise a new one, making it impossible to fetch the
3022 original errno, or to filter timeout errors. Now the original error is
3023 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003025- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3026 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3027 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003028
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003029- Updates to the random module:
3030
Georg Brandl27a28582010-10-10 09:49:21 +00003031 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003034 * Update the seed() method to use all of the bits in a string instead of just
3035 the hash value. This makes better use of the seed value and assures the
3036 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003038 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3039 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3040 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003041
3042 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003061- hashlib has two new constant attributes: algorithms_guaranteed and
3062 algorithms_avaiable that respectively list the names of hash algorithms
3063 guaranteed to exist in all Python implementations and the names of hash
3064 algorithms available in the current process.

Ezio Melotti57221d02010-07-01 07:32:02 +00003576- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003577 start byte and the continuation byte(s) are now considered invalid, instead of
3578 the number of bytes specified by the start byte. E.g.:
3579 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3580 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3581 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3582 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003612- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003613 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003625- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3626 TypeError instead of giving a DeprecationWarning when a float is parsed using
3627 the 'L' code (for long long). (All other integer codes already raise
3628 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003629

3632 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3633
Georg Brandl62069d32010-07-31 08:56:11 +00003634- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol

Georg Brandl62069d32010-07-31 08:56:11 +00003638 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003639 like bytearray.

Georg Brandl62069d32010-07-31 08:56:11 +00003641- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

3655 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003656 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3657 (2) The comparison raised an OverflowError for large integers, leading to
3658 unpredictable exceptions when combining integers and complex objects in sets

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003961- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the

3963 `va_copy`, but available on all python platforms.
3964
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003965- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3966 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3967 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003977- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003978 function declaration, which was kept for backwards compatibility reasons, is
3979 now removed (the macro was introduced in 1997!).

3989 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3990 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003991 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004001- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4002 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4003 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4020 gives improved memory leak detection when running under Valgrind, while taking
4021 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004098 applications that use a lot of regular expressions and limits the impact of
4099 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004111- Issue #7989: Added pure python implementation of the `datetime` module. The C
4112 module is renamed to `_datetime` and if available, overrides all classes
4113 defined in datetime with fast C impementation. Python implementation is based
4114 on the original python prototype for the datetime module by Tim Peters with
4115 minor modifications by the PyPy project. The test suite now tests `datetime`
4116 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004337- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
4338 messages when accessing undefined class attributes because of the cheap
4339 inheritance with the underlying socket object. The cheap inheritance has been
4340 deprecated.

Georg Brandl62069d32010-07-31 08:56:11 +00004353- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4354 operation raises multiple signals and more than one of those signals is
4355 trapped, the specification determines the order in which the signals should be
4356 handled. In many cases this order wasn't being followed, leading to the wrong
4357 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004396- Issue #8524: When creating an SSL socket, the timeout value of the original
4397 socket wasn't retained (instead, a socket with a positive timeout would be
4398 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004399
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004400- Issue #5103: SSL handshake would ignore the socket timeout and block
4401 indefinitely if the other end didn't respond.
4402
Georg Brandl62069d32010-07-31 08:56:11 +00004403- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004419- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4420 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004421 wanting to continue using the socket in clear-text mode, by disabling

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004472 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004473 relies on the system threading library, so as to avoid a semi-busy wait loop.

4509 InvalidOperation instead of returning False. (Comparisons involving a quiet
4510 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4511 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004513- Issue #2531: Comparison operations between floats and Decimal instances now
4514 return a result based on the numeric values of the operands; previously they
4515 returned an arbitrary result based on the relative ordering of id(float) and
4516 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4517 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004518
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004519- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004521- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004522 argument `-` which tells it to read files to compile from stdin. Each line is

4532 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4533 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004580- subprocess.Popen now has restore_signals and start_new_session features. The
4581 default of restore_signals=True is a new behavior compared to earlier Python
4582 versions. This means that signals such as SIGPIPE are not ignored by default
4583 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004860 default when instantiating a `threading.RLock` object. This makes recursive
4861 locks as fast as regular non-recursive locks (previously, they were slower by

5075
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005076- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005077 compared to other unix systems. In particular, os.getgroups() does not reflect
5078 any changes made using os.setgroups() but basicly always returns the same
5079 information as the id command. os.getgroups() can now return more than 16
5080 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00005105- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5106 Prior to this change, timezone adjustment in utctimetuple() could produce
5107 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5108 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005110- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5111 directive. When the ``%z`` directive is present in the format string, an
5112 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5113 ``datetime.timezone`` instance constructed from the parsed offset. If both
5114 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5115 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005116
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005117- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005118 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5119 ``datetime.timezone``, return fixed name and UTC offset from their
5120 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5121 returns ``None``. A class attribute, ``utc`` contains an instance
5122 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005138- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5139 with an improved 'binary-split' algorithm that uses fewer multiplications and
5140 allows many of the multiplications to be performed using plain C integer
5141 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5142 arguments.

5146
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005147- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5148 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005149 the result is now always correctly rounded, and is equivalent to ``td /
5150 timedelta(seconds=1)``.

Mark Dickinsonc5935772010-04-03 15:54:36 +00005158- Issue #8300: When passing a non-integer argument to struct.pack with any
5159 integer format code, struct.pack first attempts to convert the non-integer
5160 using its __index__ method. If that method is non-existent or raises
5161 TypeError it goes on to try the __int__ method, as described below.
5162

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005610- Issue #5829: complex("1e500") no longer raises OverflowError. This
5611 makes it consistent with float("1e500") and interpretation of real
5612 and imaginary literals.
5613
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005614- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

5619 (1) inf and nan strings with trailing whitespace were incorrectly
5620 rejected; (2) parsing of strings representing infinities and nans
5621 was locale aware; and (3) the interpretation of fromhex('-nan')

5639
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005640- In unittest, using a skipping decorator on a class is now equivalent to

5642
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005643- Issue #6050: Don't fail extracting a directory from a zipfile if

5645
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005646- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5647 than an int, which makes some operations possible under 64-bit Linux (e.g.
5648 DN_MULTISHOT with F_NOTIFY).
5649
Antoine Pitrou716c4442009-05-23 19:04:03 +00005650- Issue #5761: Add the name of the underlying file to the repr() of various

5671
Antoine Pitroue4501852009-05-14 18:55:55 +00005672- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5673 library. This means, for example, that opening an UTF-16 text file in
5674 append mode doesn't add a BOM at the end of the file if the file isn't
5675 empty.
5676
R. David Murray74b89242009-05-13 17:33:03 +00005677- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

Georg Brandl5f90d792010-08-01 22:31:05 +00005681- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005682 now it does. This also means getfp method now returns the real fp.

5726-----------------
5727
Mark Dickinson865e01a2009-05-07 16:37:01 +00005728- Issue #5914: Add new C API function PyOS_string_to_double, and
5729 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5730
Eric Smith741191f2009-05-06 13:08:15 +00005731- Issue #3382: float.__format__, complex.__format__, and %-formatting
5732 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5733 affects nan -> NAN and inf -> INF.
5734
Mark Hammond5a607a32009-05-06 08:04:54 +00005735- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5736 in all operations, including splitdrive, split, etc. splitunc() now issues
5737 a PendingDeprecation warning.
5738
Eric Smith63376222009-05-05 14:04:18 +00005739- Issue #5920: For float.__format__, change the behavior with the
5740 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5741 to be like 'g' but with at least one decimal point and with a
5742 default precision of 12. Previously, the behavior the same but with
5743 a default precision of 6. This more closely matches str(), and
5744 reduces surprises when adding alignment flags to the empty
5745 presentation type. This also affects the new complex.__format__ in
5746 the same way.
5747
Martin v. Löwis011e8422009-05-05 04:43:17 +00005748- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5749
R. David Murrayb18500d2009-05-04 22:59:07 +00005750- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5751 shadowed by classtype's, even if it was None. property now
5752 inserts the __doc__ into the subclass instance __dict__.
5753
Antoine Pitrou244651a2009-05-04 18:56:13 +00005754- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5755 sequences. Patch by Nick Barnes and Victor Stinner.
5756
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005757- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005758
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005759- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5760 received a new method, detach(). detach() disconnects the underlying stream
5761 from the buffer or text IO and returns it.
5762
Mark Dickinson33841c32009-05-01 15:37:04 +00005763- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5764 floats with absolute value over 1e50. Also remove length
5765 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5766 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005767
Eric Smith741191f2009-05-06 13:08:15 +00005768- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005769 format(complex(1, 2./3), '.5') now produces a sensible result.
5770
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005771- Issue #5864: Fix empty format code formatting for floats so that it
5772 never gives more than the requested number of significant digits.
5773
Eric Smith6dc46f52009-04-27 20:39:49 +00005774- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5775 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5776
Eric Smithcc32a112009-04-26 21:35:14 +00005777- Issue #5835: Deprecate PyOS_ascii_formatd.
5778
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005779- Issue #4971: Fix titlecase for characters that are their own
5780 titlecase, but not their own uppercase.
5781
Benjamin Peterson193152c2009-04-25 01:08:45 +00005782- Issue #5283: Setting __class__ in __del__ caused a segfault.
5783
Mark Dickinsonad476da2009-04-23 19:14:16 +00005784- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5785 z involves nans, infs or negative zeros.
5786
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005787- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005788
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005789- Issue #1869 (and many duplicates): make round(x, n) correctly
5790 rounded for a float x, by using the decimal <-> binary conversions
5791 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5792 consistently agrees with format(x, '.2f').
5793
Benjamin Petersonae937c02009-04-18 20:54:08 +00005794- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5795 some builtin types.
5796
Eric Smith0923d1d2009-04-16 20:16:10 +00005797- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5798
Eric Smith35e84722009-04-16 20:21:28 +00005799- Issue #5515: str.format() type 'n' combined with commas and leading
5800 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005801
5802- Implement PEP 378, Format Specifier for Thousands Separator, for
5803 floats.
5804
Mark Dickinson3370cce2009-04-17 22:40:53 +00005805- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005806 1e11, not 1e12. This avoids printing 13 significant digits in
5807 situations where only 12 of them are correct. Example problem
5808 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005811- Issue #1580: On most platforms, use a 'short' float repr: for a
5812 finite float x, repr(x) now outputs a string based on the shortest
5813 sequence of decimal digits that rounds to x. Previous behaviour was
5814 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005815 Another minor difference is that the new repr switches to
5816 exponential notation at 1e16 instead of the previous 1e17; this
5817 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005818
5819 There's a new sys attribute sys.float_repr_style, which takes
5820 the value 'short' to indicate that we're using short float repr,
5821 and 'legacy' if the short float repr isn't available for one
5822 reason or another.
5823
5824 The float repr change involves incorporating David Gay's 'perfect
5825 rounding' code into the Python core (it's in Python/dtoa.c). As a
5826 secondary consequence, all string-to-float and float-to-string
5827 conversions (including all float formatting operations) will be
5828 correctly rounded on these platforms.
5829
Georg Brandl5f90d792010-08-01 22:31:05 +00005830 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005831 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005833- Issue #5759: float() didn't call __float__ on str subclasses.
5834
Georg Brandlabc38772009-04-12 15:51:51 +00005835- The string.maketrans() function is deprecated; there is a new static method
5836 maketrans() on the bytes and bytearray classes. This removes confusion about
5837 the types string.maketrans() is supposed to work with, and mirrors the
5838 methods available on the str class.

6125
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006126- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6127 source has already been decoded into str.
6128
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006129- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6130 rotating the object pointer by 4 bits to the right.
6131
Mark Dickinson87ec0852009-02-09 17:15:59 +00006132- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6133 it now forces its argument to double before testing for infinity.
6134
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006135- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsone94c6792009-02-02 20:36:42 +00006142 the type definition cmpfunc. The tp_compare slot has been renamed
6143 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006144
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006145- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006146 were suppressing all exceptions. These include list() and bytearray().

6150
Antoine Pitroub52ec782009-01-25 16:34:23 +00006151- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6152 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6153 evaluation loop is compiled with a new dispatch mechanism which gives
6154 speedups of up to 20%, depending on the system, on various benchmarks.
6155
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006156- Issue #4874: Most builtin decoders now reject unicode input.

6162
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006163- Issue #4838: When a module is deallocated, free the memory backing the
6164 optional module state data.
6165
Mark Dickinson8055afd2009-01-17 10:04:45 +00006166- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006167 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006168
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006169- Issue #4935: The overflow checking code in the expandtabs() method common
6170 to str, bytes and bytearray could be optimized away by the compiler, letting
6171 the interpreter segfault instead of raising an error.
6172
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006173- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6174 __next__ method.
6175
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006176- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6177 function no longer attempt to call the __long__ slot to convert an object
6178 to an integer. Only the __int__ and __trunc__ slots are examined.
6179
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006180- Issue #4893: Use NT threading on CE.
6181
Martin v. Löwisec59d042009-01-12 07:59:10 +00006182- Issue #4915: Port sysmodule to Windows CE.
6183
Antoine Pitrouab868312009-01-10 15:40:25 +00006184- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6185 common cases are optimized thanks to a dedicated fast path and a moderate
6186 amount of loop unrolling.
6187
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006188- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6189 collecting the oldest generation) so that allocating lots of objects without
6190 destroying them does not show quadratic performance. Based on a proposal by
6191 Martin von Löwis at
6192 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6193
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006194- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006195 having been closed (for instance, a read() call could return some
6196 previously buffered data). Patch by Dmitry Vasiliev.
6197
Antoine Pitrou05608432009-01-09 18:53:14 +00006198- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6199 flag to work properly. Furthermore, when specifying -u, the text stdout
6200 and stderr streams have line-by-line buffering enabled (the default being
6201 to buffer arbitrary chunks of data).
6202
Raymond Hettinger35631532009-01-09 03:58:09 +00006203- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6204 instead of ints (reducing its size from 4 to 8 times thereby reducing
6205 Python's overall memory).
6206
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006207- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6208 an existing .py counterpart, override the co_filename attributes of all
6209 code objects if the original filename is obsolete (which can happen if the
6210 file has been renamed, moved, or if it is accessed through different paths).
6211 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6212
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006213- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6214 one byte. Also fixes the meaning of len() so that it returns the number of
6215 items, rather than the size in bytes.
6216
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006217- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6218
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006219- Issue #4747: When the terminal does not use utf-8, executing a script with
6220 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6221
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006222- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6223 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006224
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006225- Issue #3680: Reference cycles created through a dict, set or deque iterator
6226 did not get collected.
6227
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006228- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6229 where the tp_hash and tp_dict slots are both NULL.
6230
Georg Brandlccc47b62008-12-28 11:44:14 +00006231- Issue #4759: None is now allowed as the first argument of
6232 bytearray.translate(). It was always allowed for bytes.translate().
6233
Skip Montanaro80072cb2008-12-23 03:51:14 +00006234- Added test case to ensure attempts to read from a file opened for writing
6235 fail.
6236
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006237- Issue #3106: Speedup some comparisons (str/str and int/int).
6238
Antoine Pitrouf289ae62008-12-18 11:06:25 +00006239- Issue #2183: Simplify and optimize bytecode for list, dict and set

6241
Antoine Pitrou621601a2008-12-17 23:18:19 +00006242- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6243 print elapsed times, not only when some objects are uncollectable /
6244 unreachable. Original patch by Neil Schemenauer.
6245
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006246- Issue #3439: Add a bit_length method to int.
6247
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006248- Issue #2173: When getting device encoding, check that return value of
6249 nl_langinfo is not the empty string. This was causing silent build
6250 failures on OS X.
6251
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006252- Issue #4597: Fixed several opcodes that weren't always propagating
6253 exceptions.
6254
6255- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006256 context manager returns a value that cannot be converted to a bool.
6257
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006258- Issue #4445: Replace "sizeof(PyBytesObject)" with
6259 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6260 bytes instances. On a typical machine this saves 3 bytes of memory
6261 (on average) per allocation of a bytes instance.
6262
Christian Heimesa872de52008-12-05 08:26:55 +00006263- Issue #4533: File read operation was dreadfully slow due to a slowly
6264 growing read buffer. Fixed by using the same growth rate algorithm as
6265 Python 2.x.
6266
Antoine Pitrou5504e892008-12-06 21:27:53 +00006267- Issue #4509: Various issues surrounding resize of bytearray objects to
6268 which there are buffer exports (e.g. memoryview instances).
6269
Georg Brandlf9734072008-12-07 15:30:06 +00006270- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6271 method on file objects with closefd=False. The file descriptor is still
6272 kept open but the file object behaves like a closed file. The ``FileIO``
6273 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006274
Antoine Pitroubc420402008-12-07 20:14:49 +00006275- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6276 larger than 1.
6277

6281
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006282- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6283 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6284 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6285 of using the replace error handler in PyUnicode_DecodeUTF8().

6316 uses the same refactored function to get gcc/ld/dllwrap versions numbers.
6317 It's `distutils.util.get_compiler_versions`. Added deprecation warnings
