Ned Deily657b2de2011-06-28 19:51:30 -0700559- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
560 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
561 interpreter process. This could cause failures in non-Distutils subprocesses
562 and was unreliable since tests or user programs could modify the interpreter
563 environment after Distutils set it. Instead, have Distutils set the the
564 deployment target only in the environment of each build subprocess. It is
565 still possible to globally override the default by setting
566 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
567 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700568 was built. Also, implement the same handling in packaging.

1709
Victor Stinnerb3c9e072011-01-04 02:07:34 +00001710- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
1711 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
1712 translates newlines (\r\n => \n).
1713
Victor Stinnerdc555402011-01-04 13:15:39 +00001714- Remove buffer API from stable ABI for now, see #10181.

Victor Stinnere6edec22011-01-04 00:29:35 +00001716- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
Amaury Forgeot d'Arca251a852011-01-03 00:19:11 +00001717 doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int

1719
Victor Stinner92be9392010-12-28 00:28:21 +00001720- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
Victor Stinnerc655a722011-07-05 11:31:49 +02001721 stdprinter.write() clamp the length to INT_MAX on Windows.
Victor Stinner92be9392010-12-28 00:28:21 +00001722
1723- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()

Georg Brandl8aa7e992010-12-28 18:30:18 +00001727 PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
1728 filesystem encoding instead of UTF-8.
Raymond Hettinger8ebe27f2010-12-21 19:24:26 +00001729
1730- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem

Georg Brandl255abdd2011-01-16 14:17:26 +00001741- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
1742 and a non-zero offset, and an attempt to read past the end of file is made
1743 (IndexError is raised instead). Patch by Ross Lagerwall.

1746 of "UTF8" in the locale module as the latter is not supported MacOSX and OpenBSD.
1747
Georg Brandl255abdd2011-01-16 14:17:26 +00001748- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
1749 than the currently problematic Apple-supplied one, when running with the
1750 64-/32-bit installer variant.
Ned Deily4ce92b22011-01-15 04:37:12 +00001751
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001752- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
1753 as unicode, and accept binary files. Add encoding and errors attributes to
Victor Stinnerc5982962011-01-14 14:11:45 +00001754 cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
1755 Linderman).
Victor Stinner5c23b8e2011-01-14 13:05:21 +00001756
Georg Brandl255abdd2011-01-16 14:17:26 +00001757- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().

Georg Brandl619e7ba2011-01-09 07:38:51 +00001769
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001770- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001771 continuation line in the formatted value has no leading white space and looks
1772 like a header. Since Generator uses Header to format all headers, this check
1773 is made for all headers in any serialized message at serialization time. This
1774 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001775
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001776- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

1781
R. David Murray92532142011-01-07 23:25:30 +00001782- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Éric Araujof0ab5d62011-05-29 03:43:59 +02001783 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001784 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001785
Éric Araujof0ab5d62011-05-29 03:43:59 +02001786- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001787 rfc2047-encoding header values with embedded newlines, leaving them without
1788 folding whitespace. It now uses the continuation_ws, as it does for
1789 continuation lines that it creates itself.
R. David Murray6f0022d2011-01-07 21:57:25 +00001790
Victor Stinner3ec899f2011-01-08 16:37:47 +00001791- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1792 time.asctime(), time.ctime() and time.strftime() functions will now format
1793 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1794 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1795 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1796 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
Alexander Belopolskyc64708a2011-01-07 19:59:19 +00001797
Antoine Pitroue85da7a2011-01-06 18:25:55 +00001798- Issue #7858: Raise an error properly when os.utime() fails under Windows

1803
Victor Stinner4bd81722011-01-06 00:49:38 +00001804- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
1805 compilation (if the input is a string).
1806
Antoine Pitrou600232b2011-01-05 21:03:42 +00001807- Issue #7995: When calling accept() on a socket with a timeout, the returned

1820 the input buffer length doesn't fit into an unsigned int (length bigger than
1821 2^32-1 bytes).
1822
Georg Brandl255abdd2011-01-16 14:17:26 +00001823- Issue #6643: Reinitialize locks held within the threading module after fork to

1849 time. `sys.stderr` now looked up at instantiation time. Fix contributed by
1850 Mark Roddy.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002430 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002775- Issue #10068: Global objects which have reference cycles with their module's
2776 dict are now cleared again. This causes issue #7140 to appear again.
2777
Victor Stinner257d38f2010-10-09 10:12:11 +00002778- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002779 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002780
Georg Brandl27a28582010-10-10 09:49:21 +00002781- ast.literal_eval() can now handle negative numbers. It is also a little more
2782 liberal in what it accepts without compromising the safety of the evaluation.
2783 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002784
Benjamin Peterson970d1882010-10-02 17:55:47 +00002785- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2786 result metaclasses can now be ABCs (see #9533).
2787
Victor Stinneraef57e32010-10-02 11:50:49 +00002788- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2789
Victor Stinner5593d8a2010-10-02 11:11:27 +00002790- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002791 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2792 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002793
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002794- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002795 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002796
Victor Stinner137c34c2010-09-29 10:25:54 +00002797- Issue #9979: Create function PyUnicode_AsWideCharString().
2798
Brett Cannon5305a992010-09-27 21:08:38 +00002799- Issue #7397: Mention that importlib.import_module() is probably what someone
2800 really wants to be using in __import__'s docstring.
2801
Georg Brandl27a28582010-10-10 09:49:21 +00002802- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2803 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002804
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002805- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002806 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002807
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002808- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2809
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002810- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2811 threads are still running. Instead, reinitialize the GIL on a second call to
2812 Py_Initialize().
2813
Georg Brandl27a28582010-10-10 09:49:21 +00002814- All SyntaxErrors now have a column offset and therefore a caret when the error
2815 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002816
Brett Cannonbc2eff32010-09-19 21:39:02 +00002817- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2818 module that was imported, but instead gets the module from sys.modules.
2819
Nick Coghlan37ee8502010-12-03 14:26:13 +00002820- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002821 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002822
Georg Brandl27a28582010-10-10 09:49:21 +00002823- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2824 with a non-empty format string. This is an effort to future-proof user
2825 code. If a derived class does not currently implement __format__ but later
2826 adds its own __format__, it would most likely break user code that had
2827 supplied a format string. This will be changed to a DeprecationWaring in
2828 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002829
Antoine Pitrou1df15362010-09-13 14:16:46 +00002830- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2831 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2832 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2833
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002834- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2835 functions from the libc caused the methods .upper() and lower() to become
2836 locale aware and created subtly wrong results.
2837
Georg Brandl27a28582010-10-10 09:49:21 +00002838- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2839 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002840
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002841- Issue #4617: Previously it was illegal to delete a name from the local
2842 namespace if it occurs as a free variable in a nested block. This limitation
2843 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2844
Georg Brandl27a28582010-10-10 09:49:21 +00002845- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2846 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2847 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2848 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002849
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002850- Issue #9757: memoryview objects get a release() method to release the
2851 underlying buffer (previously this was only done when deallocating the
2852 memoryview), and gain support for the context management protocol.
2853
Antoine Pitrou079ce542010-09-08 12:37:10 +00002854- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2855 thread-local storage key.

2867 not in build_clib.
2868
Antoine Pitroudbec7802010-10-10 09:37:12 +00002869- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2870
R. David Murray96fd54e2010-10-08 15:55:28 +00002871- Issue #4661: email can now parse bytes input and generate either converted
2872 7bit output or bytes output. Email version bumped to 5.1.0.
2873
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002874- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2875 verification for higher-level protocols.
2876
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002877- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2878 after the file is closed. Patch by Jeffrey Finkelstein.
2879
Éric Araujo6108bf52010-10-04 23:52:37 +00002880- Issue #9042: Fix interaction of custom translation classes and caching in
2881 gettext.
2882
Éric Araujoef777bd2010-10-05 00:04:20 +00002883- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002884 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002885 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002886 replacement for old handle_accept() and avoids the user to call accept()
2887 directly.
2888
Lars Gustäbel331b8002010-10-04 15:18:47 +00002889- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2890 gname field.

Georg Brandl27a28582010-10-10 09:49:21 +00002892- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2893 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002894
R. David Murray5397e862010-10-02 15:58:26 +00002895- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2896 characters that appear inside quoted strings in email addresses.
2897
Georg Brandl27a28582010-10-10 09:49:21 +00002898- Issue #10004: quoprimime no longer generates a traceback when confronted with
2899 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002900
Georg Brandl27a28582010-10-10 09:49:21 +00002901- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2902 sending a 200 OK for the Expect: 100-continue request header.

2905 conforms to the philosophy of bytes and unicode separation in Python 3. A
2906 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002908- Issue #9962: GzipFile now has the peek() method.
2909
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002910- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002911 retry the select() loop instead of bailing out. This is because select() can
2912 incorrectly report a socket as ready for reading (for example, if it received
2913 some data with an invalid checksum).

Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002915- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Georg Brandl27a28582010-10-10 09:49:21 +00002918 received. Now sendall() properly calls signal handlers if necessary, and
2919 retries sending if these returned successfully, including on sockets with a
2920 timeout.

2958
Antoine Pitrou98b46702010-09-18 22:59:00 +00002959- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002960 non-blocking mode: they return None when an operation would block (instead of
2961 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00002962
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00002963- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00002973- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2974 supporting the whole socket API (rather than the "raw" _socket.socket

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002993- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002994 it possible for the user to create self-referencing ordered dictionaries which
2995 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002996 approach of using weakref proxies so that reference cycles never get created
2997 in the first place.
2998
Victor Stinnercb043522010-09-10 23:49:04 +00002999- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
3000 encode the value with filesystem encoding and surrogateescape (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00003003- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3004 environment variable to set the filesystem encoding at Python startup.
3005 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3006 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003007
Georg Brandl27a28582010-10-10 09:49:21 +00003008- Issue #9410: Various optimizations to the pickle module, leading to speedups

3016 multiprocessing.
3017
Georg Brandl27a28582010-10-10 09:49:21 +00003018- Issue #9707: Rewritten reference implementation of threading.local which is
3019 friendlier towards reference cycles. This change is not normally visible
3020 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003021
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003022- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3023 still return the id of the parent process after it has exited. This process
3024 id may even have been reused by another unrelated process.
3025
Georg Brandl27a28582010-10-10 09:49:21 +00003026- Issue #9792: In case of connection failure, socket.create_connection() would
3027 swallow the exception and raise a new one, making it impossible to fetch the
3028 original errno, or to filter timeout errors. Now the original error is
3029 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003031- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3032 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3033 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003034
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003035- Updates to the random module:
3036
Georg Brandl27a28582010-10-10 09:49:21 +00003037 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003044 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3045 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3046 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003047
3048 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003067- hashlib has two new constant attributes: algorithms_guaranteed and
3068 algorithms_avaiable that respectively list the names of hash algorithms
3069 guaranteed to exist in all Python implementations and the names of hash
3070 algorithms available in the current process.
3071

Ezio Melotti57221d02010-07-01 07:32:02 +00003582- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003583 start byte and the continuation byte(s) are now considered invalid, instead of
3584 the number of bytes specified by the start byte. E.g.:
3585 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3586 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3587 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3588 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003618- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003619 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

3632 TypeError instead of giving a DeprecationWarning when a float is parsed using
3633 the 'L' code (for long long). (All other integer codes already raise
3634 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00003644 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003645 like bytearray.

Georg Brandl62069d32010-07-31 08:56:11 +00003647- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no

3661 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003662 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3663 (2) The comparison raised an OverflowError for large integers, leading to
3664 unpredictable exceptions when combining integers and complex objects in sets
3665 or dicts.

3995 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3996 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003997 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004007- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
4008 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
4009 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4026 gives improved memory leak detection when running under Valgrind, while taking
4027 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004104 applications that use a lot of regular expressions and limits the impact of
4105 the performance hit anytime the cache is exceeded.

4118 module is renamed to `_datetime` and if available, overrides all classes
4119 defined in datetime with fast C impementation. Python implementation is based
4120 on the original python prototype for the datetime module by Tim Peters with
4121 minor modifications by the PyPy project. The test suite now tests `datetime`
4122 module with and without `_datetime` acceleration using the same test cases.

4337 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
4338 file system encoding with the surrogateescape error handler (instead of
4339 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

4342
Georg Brandl62069d32010-07-31 08:56:11 +00004343- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
4344 messages when accessing undefined class attributes because of the cheap
4345 inheritance with the underlying socket object. The cheap inheritance has been
4346 deprecated.

4350
Victor Stinnerd17f2192010-08-15 09:56:07 +00004351- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00004352 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00004359- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4360 operation raises multiple signals and more than one of those signals is
4361 trapped, the specification determines the order in which the signals should be
4362 handled. In many cases this order wasn't being followed, leading to the wrong
4363 Python exception being raised.

4371
Georg Brandl62069d32010-07-31 08:56:11 +00004372- Issue #8354: The siginterrupt setting is now preserved for all signals, not

Georg Brandl62069d32010-07-31 08:56:11 +00004397- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4398 the method could block indefinitely if called just before the event loop
4399 started running. This also fixes the occasional freezes witnessed in
4400 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00004402- Issue #8524: When creating an SSL socket, the timeout value of the original
4403 socket wasn't retained (instead, a socket with a positive timeout would be
4404 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004405
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004406- Issue #5103: SSL handshake would ignore the socket timeout and block
4407 indefinitely if the other end didn't respond.
4408
Georg Brandl62069d32010-07-31 08:56:11 +00004409- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004421- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
4422 string "python" as the *ident*. openlog() arguments are all optional and
4423 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00004424
Georg Brandl62069d32010-07-31 08:56:11 +00004425- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4426 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004427 wanting to continue using the socket in clear-text mode, by disabling
4428 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004478 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004479 relies on the system threading library, so as to avoid a semi-busy wait loop.

R. David Murrayb2416e52010-04-12 16:58:02 +00004485- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004486 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00004514- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4515 InvalidOperation instead of returning False. (Comparisons involving a quiet
4516 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4517 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004519- Issue #2531: Comparison operations between floats and Decimal instances now
4520 return a result based on the numeric values of the operands; previously they
4521 returned an arbitrary result based on the relative ordering of id(float) and
4522 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4523 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004524
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004525- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004527- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004528 argument `-` which tells it to read files to compile from stdin. Each line is

4537 Fractions instance now raise TypeError instead of returning True/False. This
4538 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4539 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005083 compared to other unix systems. In particular, os.getgroups() does not reflect

Antoine Pitroue4501852009-05-14 18:55:55 +00005678- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5679 library. This means, for example, that opening an UTF-16 text file in
5680 append mode doesn't add a BOM at the end of the file if the file isn't

Mark Dickinson865e01a2009-05-07 16:37:01 +00005734- Issue #5914: Add new C API function PyOS_string_to_double, and
5735 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5736
Eric Smith741191f2009-05-06 13:08:15 +00005737- Issue #3382: float.__format__, complex.__format__, and %-formatting

5742 in all operations, including splitdrive, split, etc. splitunc() now issues
5743 a PendingDeprecation warning.
5744
Eric Smith63376222009-05-05 14:04:18 +00005745- Issue #5920: For float.__format__, change the behavior with the
5746 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5747 to be like 'g' but with at least one decimal point and with a
5748 default precision of 12. Previously, the behavior the same but with
5749 a default precision of 6. This more closely matches str(), and
5750 reduces surprises when adding alignment flags to the empty
5751 presentation type. This also affects the new complex.__format__ in
5752 the same way.
5753
Martin v. Löwis011e8422009-05-05 04:43:17 +00005754- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00005756- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5757 shadowed by classtype's, even if it was None. property now
5758 inserts the __doc__ into the subclass instance __dict__.
5759

Benjamin Petersond2e0c792009-05-01 20:40:59 +00005765- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5766 received a new method, detach(). detach() disconnects the underlying stream
5767 from the buffer or text IO and returns it.
5768
Mark Dickinson33841c32009-05-01 15:37:04 +00005769- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5770 floats with absolute value over 1e50. Also remove length
5771 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5772 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00005775 format(complex(1, 2./3), '.5') now produces a sensible result.
5776

5778 never gives more than the requested number of significant digits.
5779
Eric Smith6dc46f52009-04-27 20:39:49 +00005780- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00005790- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5791 z involves nans, infs or negative zeros.
5792
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005793- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005795- Issue #1869 (and many duplicates): make round(x, n) correctly
5796 rounded for a float x, by using the decimal <-> binary conversions
5797 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5798 consistently agrees with format(x, '.2f').
5799
Benjamin Petersonae937c02009-04-18 20:54:08 +00005800- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5806 zeros no longer gives odd results with ints and floats.

5808- Implement PEP 378, Format Specifier for Thousands Separator, for
5809 floats.
5810
Mark Dickinson3370cce2009-04-17 22:40:53 +00005811- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005812 1e11, not 1e12. This avoids printing 13 significant digits in
5813 situations where only 12 of them are correct. Example problem
5814 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5815 long time.)
5816
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005817- Issue #1580: On most platforms, use a 'short' float repr: for a
5818 finite float x, repr(x) now outputs a string based on the shortest
5819 sequence of decimal digits that rounds to x. Previous behaviour was
5820 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005821 Another minor difference is that the new repr switches to
5822 exponential notation at 1e16 instead of the previous 1e17; this
5823 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005824
5825 There's a new sys attribute sys.float_repr_style, which takes
5826 the value 'short' to indicate that we're using short float repr,
5827 and 'legacy' if the short float repr isn't available for one
5828 reason or another.
5829
5830 The float repr change involves incorporating David Gay's 'perfect
5831 rounding' code into the Python core (it's in Python/dtoa.c). As a
5832 secondary consequence, all string-to-float and float-to-string
5833 conversions (including all float formatting operations) will be
5834 correctly rounded on these platforms.
5835
Georg Brandl5f90d792010-08-01 22:31:05 +00005836 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005837 this change does not apply.
5838
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005839- Issue #5759: float() didn't call __float__ on str subclasses.
5840
Georg Brandlabc38772009-04-12 15:51:51 +00005841- The string.maketrans() function is deprecated; there is a new static method
5842 maketrans() on the bytes and bytearray classes. This removes confusion about
5843 the types string.maketrans() is supposed to work with, and mirrors the
5844 methods available on the str class.
5845
R. David Murraydc6da8a2009-04-09 22:16:43 +00005846- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsonb40b9472009-03-29 16:58:21 +00006109 struct.error instead of returning b'\xff\xff\xff\xff'. The
6110 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6111 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00006138- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6139 it now forces its argument to double before testing for infinity.
6140
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006141- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006150
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006151- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006152 were suppressing all exceptions. These include list() and bytearray().

6156
Antoine Pitroub52ec782009-01-25 16:34:23 +00006157- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6158 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6159 evaluation loop is compiled with a new dispatch mechanism which gives
6160 speedups of up to 20%, depending on the system, on various benchmarks.
6161

6170 optional module state data.
6171
Mark Dickinson8055afd2009-01-17 10:04:45 +00006172- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006173 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006174
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006175- Issue #4935: The overflow checking code in the expandtabs() method common
6176 to str, bytes and bytearray could be optimized away by the compiler, letting
6177 the interpreter segfault instead of raising an error.
6178
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006179- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6180 __next__ method.
6181
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006182- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6183 function no longer attempt to call the __long__ slot to convert an object
6184 to an integer. Only the __int__ and __trunc__ slots are examined.
6185
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006186- Issue #4893: Use NT threading on CE.
6187

6189
Antoine Pitrouab868312009-01-10 15:40:25 +00006190- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6191 common cases are optimized thanks to a dedicated fast path and a moderate
6192 amount of loop unrolling.
6193
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006194- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6195 collecting the oldest generation) so that allocating lots of objects without
6196 destroying them does not show quadratic performance. Based on a proposal by
6197 Martin von Löwis at
6198 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6199
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006200- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006201 having been closed (for instance, a read() call could return some
6202 previously buffered data). Patch by Dmitry Vasiliev.
6203
Antoine Pitrou05608432009-01-09 18:53:14 +00006204- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6205 flag to work properly. Furthermore, when specifying -u, the text stdout
6206 and stderr streams have line-by-line buffering enabled (the default being
6207 to buffer arbitrary chunks of data).
6208
Raymond Hettinger35631532009-01-09 03:58:09 +00006209- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6210 instead of ints (reducing its size from 4 to 8 times thereby reducing
6211 Python's overall memory).
6212
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006213- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6214 an existing .py counterpart, override the co_filename attributes of all
6215 code objects if the original filename is obsolete (which can happen if the
6216 file has been renamed, moved, or if it is accessed through different paths).
6217 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6218
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006219- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6220 one byte. Also fixes the meaning of len() so that it returns the number of
6221 items, rather than the size in bytes.
6222
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006223- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6224
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006225- Issue #4747: When the terminal does not use utf-8, executing a script with
6226 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6227
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006228- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6229 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006230
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006231- Issue #3680: Reference cycles created through a dict, set or deque iterator
6232 did not get collected.
6233
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006234- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6235 where the tp_hash and tp_dict slots are both NULL.
6236
Georg Brandlccc47b62008-12-28 11:44:14 +00006237- Issue #4759: None is now allowed as the first argument of
6238 bytearray.translate(). It was always allowed for bytes.translate().
6239
Skip Montanaro80072cb2008-12-23 03:51:14 +00006240- Added test case to ensure attempts to read from a file opened for writing
6241 fail.
6242
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006243- Issue #3106: Speedup some comparisons (str/str and int/int).

6247
Antoine Pitrou621601a2008-12-17 23:18:19 +00006248- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6249 print elapsed times, not only when some objects are uncollectable /
6250 unreachable. Original patch by Neil Schemenauer.
6251
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006252- Issue #3439: Add a bit_length method to int.
6253
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006254- Issue #2173: When getting device encoding, check that return value of
6255 nl_langinfo is not the empty string. This was causing silent build
6256 failures on OS X.
6257
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006258- Issue #4597: Fixed several opcodes that weren't always propagating
6259 exceptions.
6260
6261- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006262 context manager returns a value that cannot be converted to a bool.
6263
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006264- Issue #4445: Replace "sizeof(PyBytesObject)" with
6265 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6266 bytes instances. On a typical machine this saves 3 bytes of memory
6267 (on average) per allocation of a bytes instance.
6268
Christian Heimesa872de52008-12-05 08:26:55 +00006269- Issue #4533: File read operation was dreadfully slow due to a slowly
6270 growing read buffer. Fixed by using the same growth rate algorithm as
6271 Python 2.x.
6272
Antoine Pitrou5504e892008-12-06 21:27:53 +00006273- Issue #4509: Various issues surrounding resize of bytearray objects to
6274 which there are buffer exports (e.g. memoryview instances).
6275
Georg Brandlf9734072008-12-07 15:30:06 +00006276- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6277 method on file objects with closefd=False. The file descriptor is still
6278 kept open but the file object behaves like a closed file. The ``FileIO``
6279 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006280
Antoine Pitroubc420402008-12-07 20:14:49 +00006281- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6282 larger than 1.

6287
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006288- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6289 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6290 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6291 of using the replace error handler in PyUnicode_DecodeUTF8().
