Victor Stinnereaf399e2011-06-30 18:10:14 +020028- Issue #12451: The XInclude default loader of xml.etree now decodes files from
29 UTF-8 instead of the locale encoding if the encoding is not specified. It now
30 also opens XML files for the parser in binary mode instead of the text mode
31 to avoid encoding issues.
32
Victor Stinner12b8d142011-06-30 17:35:55 +020033- Issue #12451: doctest.debug_script() doesn't create a temporary file
34 anymore to avoid encoding issues.

37 to read the Python script from the right encoding.
38
Victor Stinnerdc9b1ea2011-06-30 15:40:22 +020039- Issue #12451: distutils now opens the setup script in binary mode to read the
40 encoding cookie, instead of opening it in UTF-8.
41
Ned Deily657b2de2011-06-28 19:51:30 -070042- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
43 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
44 interpreter process. This could cause failures in non-Distutils subprocesses
45 and was unreliable since tests or user programs could modify the interpreter
46 environment after Distutils set it. Instead, have Distutils set the the
47 deployment target only in the environment of each build subprocess. It is
48 still possible to globally override the default by setting
49 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
50 greater or equal to the default value, the value with which the interpreter
51 was built.
52
Ross Lagerwalldbfb9b82011-06-25 10:02:37 +020053- Issue #12404: Remove C89 incompatible code from mmap module. Patch by Akira

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001547 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001548 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001549 encoding and to encode command line arguments on this OS.

1552 filenames encoded to the filesystem encoding with the surrogateescape error

Georg Brandlbad09252010-09-05 21:29:17 +00001885What's New in Python 3.2 Alpha 3?
1886=================================
1887
Georg Brandl002fa2d2010-10-10 09:40:34 +00001888*Release date: 09-Oct-2010*
Georg Brandlbad09252010-09-05 21:29:17 +00001889
1890Core and Builtins
1891-----------------
1892
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001893- Issue #10068: Global objects which have reference cycles with their module's
1894 dict are now cleared again. This causes issue #7140 to appear again.
1895
Victor Stinner257d38f2010-10-09 10:12:11 +00001896- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001897 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001898
Georg Brandl27a28582010-10-10 09:49:21 +00001899- ast.literal_eval() can now handle negative numbers. It is also a little more
1900 liberal in what it accepts without compromising the safety of the evaluation.
1901 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001902
Benjamin Peterson970d1882010-10-02 17:55:47 +00001903- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1904 result metaclasses can now be ABCs (see #9533).
1905
Victor Stinneraef57e32010-10-02 11:50:49 +00001906- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1907
Victor Stinner5593d8a2010-10-02 11:11:27 +00001908- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001909 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
1910 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00001911
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001912- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00001913 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001914
Victor Stinner137c34c2010-09-29 10:25:54 +00001915- Issue #9979: Create function PyUnicode_AsWideCharString().
1916
Brett Cannon5305a992010-09-27 21:08:38 +00001917- Issue #7397: Mention that importlib.import_module() is probably what someone
1918 really wants to be using in __import__'s docstring.
1919
Georg Brandl27a28582010-10-10 09:49:21 +00001920- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1921 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00001922
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001923- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001924 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001925
Brian Curtine8e4b3b2010-09-23 20:04:14 +00001926- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1927
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001928- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1929 threads are still running. Instead, reinitialize the GIL on a second call to
1930 Py_Initialize().
1931
Georg Brandl27a28582010-10-10 09:49:21 +00001932- All SyntaxErrors now have a column offset and therefore a caret when the error
1933 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001934
Brett Cannonbc2eff32010-09-19 21:39:02 +00001935- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1936 module that was imported, but instead gets the module from sys.modules.
1937
Nick Coghlan37ee8502010-12-03 14:26:13 +00001938- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001939 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001940
Georg Brandl27a28582010-10-10 09:49:21 +00001941- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1942 with a non-empty format string. This is an effort to future-proof user
1943 code. If a derived class does not currently implement __format__ but later
1944 adds its own __format__, it would most likely break user code that had
1945 supplied a format string. This will be changed to a DeprecationWaring in
1946 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001947
Antoine Pitrou1df15362010-09-13 14:16:46 +00001948- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1949 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1950 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1951
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001952- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1953 functions from the libc caused the methods .upper() and lower() to become
1954 locale aware and created subtly wrong results.
1955
Georg Brandl27a28582010-10-10 09:49:21 +00001956- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1957 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001958
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001959- Issue #4617: Previously it was illegal to delete a name from the local
1960 namespace if it occurs as a free variable in a nested block. This limitation
1961 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1962
Georg Brandl27a28582010-10-10 09:49:21 +00001963- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1964 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1965 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1966 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001967
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001968- Issue #9757: memoryview objects get a release() method to release the
1969 underlying buffer (previously this was only done when deallocating the
1970 memoryview), and gain support for the context management protocol.
1971
Antoine Pitrou079ce542010-09-08 12:37:10 +00001972- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1973 thread-local storage key.
1974
Georg Brandlbad09252010-09-05 21:29:17 +00001975Library
1976-------
1977
Éric Araujo0cfba092010-11-08 21:48:23 +00001978- Issue #2236: distutils' mkpath ignored the mode parameter.
1979
Éric Araujoe7cf9542010-11-06 15:01:07 +00001980- Fix typo in one sdist option (medata-check).
1981
1982- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
1983
1984- Issue #1718574: Fix options that were supposed to accept arguments but did
1985 not in build_clib.
1986
Antoine Pitroudbec7802010-10-10 09:37:12 +00001987- Issue #9437: Fix building C extensions with non-default LDFLAGS.
1988
R. David Murray96fd54e2010-10-08 15:55:28 +00001989- Issue #4661: email can now parse bytes input and generate either converted
1990 7bit output or bytes output. Email version bumped to 5.1.0.
1991
Antoine Pitrou59fdd672010-10-08 10:37:08 +00001992- Issue #1589: Add ssl.match_hostname(), to help implement server identity
1993 verification for higher-level protocols.
1994
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00001995- Issue #9759: GzipFile now raises ValueError when an operation is attempted
1996 after the file is closed. Patch by Jeffrey Finkelstein.
1997
Éric Araujo6108bf52010-10-04 23:52:37 +00001998- Issue #9042: Fix interaction of custom translation classes and caching in
1999 gettext.
2000
Éric Araujoef777bd2010-10-05 00:04:20 +00002001- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002002 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002003 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002004 replacement for old handle_accept() and avoids the user to call accept()
2005 directly.
2006
Lars Gustäbel331b8002010-10-04 15:18:47 +00002007- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2008 gname field.
2009
Georg Brandl27a28582010-10-10 09:49:21 +00002010- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2011 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002012
R. David Murray5397e862010-10-02 15:58:26 +00002013- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2014 characters that appear inside quoted strings in email addresses.
2015
Georg Brandl27a28582010-10-10 09:49:21 +00002016- Issue #10004: quoprimime no longer generates a traceback when confronted with
2017 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002018
Georg Brandl27a28582010-10-10 09:49:21 +00002019- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2020 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002021
Georg Brandl27a28582010-10-10 09:49:21 +00002022- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2023 conforms to the philosophy of bytes and unicode separation in Python 3. A
2024 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002025
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002026- Issue #9962: GzipFile now has the peek() method.
2027
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002028- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002029 retry the select() loop instead of bailing out. This is because select() can
2030 incorrectly report a socket as ready for reading (for example, if it received
2031 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002032
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002033- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2034
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002035- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002036 received. Now sendall() properly calls signal handlers if necessary, and
2037 retries sending if these returned successfully, including on sockets with a
2038 timeout.
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002039
Vinay Sajip9fdd11b2010-09-25 17:48:25 +00002040- Issue #9947: logging: Fixed locking bug in stopListening.

2048
Antoine Pitrou70c60442010-09-23 19:51:39 +00002049- Issue #9928: Properly initialize the types exported by the bz2 module.

2055 performance-critical threads.
2056

2061- logging: Added hasHandlers() method to Logger and LoggerAdapter.
2062
Antoine Pitrou38425292010-09-21 18:19:07 +00002063- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
2064
Antoine Pitrou52d42502010-09-21 16:08:27 +00002065- Issue #2643: msync() is not called anymore when deallocating an open mmap
2066 object, only munmap().
2067
Georg Brandl27a28582010-10-10 09:49:21 +00002068- logging: Changed LoggerAdapter implementation internally, to make it easier to
2069 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002070
Vinay Sajipc84f0162010-09-21 11:25:39 +00002071- logging: hasHandlers method was added to Logger, and isEnabledFor,
2072 getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
2073 LoggerAdapter was introduced into the unit tests for logging.
2074
Florent Xiclunaeb19dce2010-09-18 23:34:07 +00002075- Issue #1686: Fix string.Template when overriding the pattern attribute.
2076
Antoine Pitrou98b46702010-09-18 22:59:00 +00002077- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002078 non-blocking mode: they return None when an operation would block (instead of
2079 raising an exception).

2089 non-blocking readinto() returning None correctly.
Antoine Pitrou328ec742010-09-14 18:37:24 +00002090
Georg Brandl27a28582010-10-10 09:49:21 +00002091- Issue #1552: socket.socketpair() now returns regular socket.socket objects
2092 supporting the whole socket API (rather than the "raw" _socket.socket
2093 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00002094

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002111- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002112 it possible for the user to create self-referencing ordered dictionaries which
2113 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002114 approach of using weakref proxies so that reference cycles never get created
2115 in the first place.
2116
Victor Stinnercb043522010-09-10 23:49:04 +00002117- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00002121- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2122 environment variable to set the filesystem encoding at Python startup.
2123 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Georg Brandl27a28582010-10-10 09:49:21 +00002126- Issue #9410: Various optimizations to the pickle module, leading to speedups
2127 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2128 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002129
Georg Brandl27a28582010-10-10 09:49:21 +00002130- The pprint module now supports printing OrderedDicts in their given order
2131 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002133- Logging: Added QueueHandler class to facilitate logging usage with
2134 multiprocessing.
2135
Georg Brandl27a28582010-10-10 09:49:21 +00002136- Issue #9707: Rewritten reference implementation of threading.local which is
2137 friendlier towards reference cycles. This change is not normally visible
2138 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002139
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002140- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2141 still return the id of the parent process after it has exited. This process
2142 id may even have been reused by another unrelated process.
2143
Georg Brandl27a28582010-10-10 09:49:21 +00002144- Issue #9792: In case of connection failure, socket.create_connection() would
2145 swallow the exception and raise a new one, making it impossible to fetch the
2146 original errno, or to filter timeout errors. Now the original error is
2147 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002149- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2150 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2151 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002153- Updates to the random module:
2154
Georg Brandl27a28582010-10-10 09:49:21 +00002155 * Document which parts of the module are guaranteed to stay the same across
2156 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002157
Georg Brandl27a28582010-10-10 09:49:21 +00002158 * Update the seed() method to use all of the bits in a string instead of just
2159 the hash value. This makes better use of the seed value and assures the
2160 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002161
Georg Brandl27a28582010-10-10 09:49:21 +00002162 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2163 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2164 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002165
2166 * Improved documentation of arguments to randrange(). Issue #9379.

2172 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2173 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002174
Georg Brandl27a28582010-10-10 09:49:21 +00002175- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002181- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002182 unsupported operation is attempted (for example, writing to a file open only
2183 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002184
Gregory P. Smith13b55292010-09-06 08:30:23 +00002185- hashlib has two new constant attributes: algorithms_guaranteed and
2186 algorithms_avaiable that respectively list the names of hash algorithms
2187 guaranteed to exist in all Python implementations and the names of hash
2188 algorithms available in the current process.
2189
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002190- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002293- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2294 now removed, since their effect was inexistent in 3.x (the default encoding is

2317 return characters from the full Unicode range, even on narrow unicode builds
2318 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2319 in Python is that unicodedata.numeric() now returns the correct value for
2320 large code points, and repr() may consider more characters as printable.
2321
Victor Stinner6c00c142010-08-17 23:37:11 +00002322- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Mark Dickinson388122d2010-08-04 20:56:28 +00002356
Georg Brandl649971e2010-09-05 17:06:50 +00002357- Issue #9416: Fix some issues with complex formatting where the output with no
2358 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002359
2360 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

2699
Ezio Melotti57221d02010-07-01 07:32:02 +00002700- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002701 start byte and the continuation byte(s) are now considered invalid, instead of
2702 the number of bytes specified by the start byte. E.g.:
2703 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2704 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2705 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2706 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002708- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2709 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00002710
Benjamin Peterson88968ad2010-06-25 19:30:21 +00002711- Be more specific in error messages about positional arguments.

Georg Brandl62069d32010-07-31 08:56:11 +00002720- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2721 dealing with unary minus applied to a constant. The removed code was mutating
2722 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002723
Victor Stinner554f3f02010-06-16 23:33:54 +00002724- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002725 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002726 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002727 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002728
Victor Stinner25e8ec42010-06-25 00:02:38 +00002729- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2730 "w*" format instead. Add tests for "w*" format.
2731
Victor Stinner06e49dd2010-06-13 18:21:50 +00002732- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002733 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002734 string formats.
2735
Georg Brandl62069d32010-07-31 08:56:11 +00002736- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002737 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2738 location of the raised exception.
2739
Victor Stinner313a1202010-06-11 23:56:51 +00002740- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2741 filenames and enable os.fsencode().
2742
Benjamin Peterson285a6892010-06-22 19:21:52 +00002743- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2744
Georg Brandl62069d32010-07-31 08:56:11 +00002745- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2746 interpreter with characters outside the Basic Multilingual Plane (higher than
2747 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002748
Georg Brandl62069d32010-07-31 08:56:11 +00002749- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2750 TypeError instead of giving a DeprecationWarning when a float is parsed using
2751 the 'L' code (for long long). (All other integer codes already raise
2752 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002753
Victor Stinner600d3be2010-06-10 12:00:55 +00002754- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2755 enable shortcuts for upper case encoding name. Add also a shortcut for
2756 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2757
Georg Brandl62069d32010-07-31 08:56:11 +00002758- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2759 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002760
2761- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002762 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002763 like bytearray.
2764
Georg Brandl62069d32010-07-31 08:56:11 +00002765- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002766 used anymore and it was never documented.
2767
Georg Brandl62069d32010-07-31 08:56:11 +00002768- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002769
Georg Brandl62069d32010-07-31 08:56:11 +00002770- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2771 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002772
Georg Brandl62069d32010-07-31 08:56:11 +00002773- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2774 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2775 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2776 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002777
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002778- Issue #8748: Fix two issues with comparisons between complex and integer
2779 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002780 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2781 (2) The comparison raised an OverflowError for large integers, leading to
2782 unpredictable exceptions when combining integers and complex objects in sets
2783 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002784
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002785- Issue #8766: Initialize _warnings module before importing the first module.
2786 Fix a crash if an empty directory called "encodings" exists in sys.path.
2787
Victor Stinner9ca9c252010-05-19 16:53:30 +00002788- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002789 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002790 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002791
Georg Brandl62069d32010-07-31 08:56:11 +00002792- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2793 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002794
Victor Stinnerae6265f2010-05-15 16:27:27 +00002795- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2796 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002797 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002798 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002799
Victor Stinner59e62db2010-05-15 13:14:32 +00002800- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002801 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002802
Victor Stinnerb744ba12010-05-15 12:27:16 +00002803- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002804 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002805 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2806
Victor Stinner0964ee12010-04-30 16:48:45 +00002807- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002808 PyUnicode_FromString() to support surrogates in the filename and use the right
2809 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002810
Georg Brandl8569e582010-05-19 20:57:08 +00002811- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2812
Georg Brandl62069d32010-07-31 08:56:11 +00002813- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002814
Benjamin Petersonfb886362010-04-24 18:21:17 +00002815- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2816 arguments.
2817
Victor Stinner14284c22010-04-23 12:02:30 +00002818- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002819 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00002829 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002912- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002913 where the right hand operand is a set of constants, by turning the set into a
2914 frozenset and pre-building it as a constant. The comparison operation is made
2915 against the constant instead of building a new set each time it is executed (a
2916 similar optimization already existed which turned a list of constants into a
2917 pre-built tuple). Patch and additional tests by Dave Malcolm.

2924 including: (1) a serious 'wrong output' bug that could occur for long (> 40
2925 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
2926 parsing certain long numeric strings corresponding to subnormal values, (3) a

2943 of integers: the result of a/b is now correctly rounded for ints a and b (at
2944 least on IEEE 754 platforms), and in particular does not depend on the
2945 internal representation of an int.

2973 long but the length of the range did not. Also fix several cases where

Mark Dickinsone6fc7402010-08-06 18:55:26 +00003089- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3090 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3113 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3114 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003115 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003125- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3126 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3127 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3144 gives improved memory leak detection when running under Valgrind, while taking
3145 advantage of pymalloc at other times.

3221 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003222 applications that use a lot of regular expressions and limits the impact of
3223 the performance hit anytime the cache is exceeded.

Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003524- Issue #5103: SSL handshake would ignore the socket timeout and block
3525 indefinitely if the other end didn't respond.
3526
Georg Brandl62069d32010-07-31 08:56:11 +00003527- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00003637- Issue #2531: Comparison operations between floats and Decimal instances now
3638 return a result based on the numeric values of the operands; previously they
3639 returned an arbitrary result based on the relative ordering of id(float) and
3640 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3641 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003645- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003646 argument `-` which tells it to read files to compile from stdin. Each line is
3647 read on demand and the named file is compiled immediately. (Original patch by

3655 Fractions instance now raise TypeError instead of returning True/False. This
3656 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3657 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003700- The internals of the subprocess module on POSIX systems have been replaced by
3701 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3702 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003704- subprocess.Popen now has restore_signals and start_new_session features. The
3705 default of restore_signals=True is a new behavior compared to earlier Python
3706 versions. This means that signals such as SIGPIPE are not ignored by default
3707 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003984 default when instantiating a `threading.RLock` object. This makes recursive
3985 locks as fast as regular non-recursive locks (previously, they were slower by
3986 10x to 15x).

4006 from stdin so that existing input does not confuse it and lead to incorrect
4007 entry or an IOError. It also properly flushes it afterwards to avoid the
4008 terminal echoing the input afterwards on OSes such as Solaris.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004200- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004201 compared to other unix systems. In particular, os.getgroups() does not reflect

Georg Brandl62069d32010-07-31 08:56:11 +00004229- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4230 Prior to this change, timezone adjustment in utctimetuple() could produce
4231 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4232 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004234- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4235 directive. When the ``%z`` directive is present in the format string, an
4236 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4237 ``datetime.timezone`` instance constructed from the parsed offset. If both
4238 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4239 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004241- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004242 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4243 ``datetime.timezone``, return fixed name and UTC offset from their
4244 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4245 returns ``None``. A class attribute, ``utc`` contains an instance
4246 representing the UTC timezone. Original patch by Rafe Kaplan.

4744 rejected; (2) parsing of strings representing infinities and nans
4745 was locale aware; and (3) the interpretation of fromhex('-nan')

4849Core and Builtins
4850-----------------
4851
Mark Dickinson865e01a2009-05-07 16:37:01 +00004852- Issue #5914: Add new C API function PyOS_string_to_double, and
4853 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4854
Eric Smith741191f2009-05-06 13:08:15 +00004855- Issue #3382: float.__format__, complex.__format__, and %-formatting
4856 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4857 affects nan -> NAN and inf -> INF.
4858
Mark Hammond5a607a32009-05-06 08:04:54 +00004859- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4860 in all operations, including splitdrive, split, etc. splitunc() now issues
4861 a PendingDeprecation warning.
4862
Eric Smith63376222009-05-05 14:04:18 +00004863- Issue #5920: For float.__format__, change the behavior with the
4864 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4865 to be like 'g' but with at least one decimal point and with a
4866 default precision of 12. Previously, the behavior the same but with
4867 a default precision of 6. This more closely matches str(), and
4868 reduces surprises when adding alignment flags to the empty
4869 presentation type. This also affects the new complex.__format__ in
4870 the same way.
4871
Martin v. Löwis011e8422009-05-05 04:43:17 +00004872- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4873
R. David Murrayb18500d2009-05-04 22:59:07 +00004874- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4875 shadowed by classtype's, even if it was None. property now
4876 inserts the __doc__ into the subclass instance __dict__.
4877
Antoine Pitrou244651a2009-05-04 18:56:13 +00004878- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4879 sequences. Patch by Nick Barnes and Victor Stinner.
4880
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004881- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004882
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004883- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4884 received a new method, detach(). detach() disconnects the underlying stream
4885 from the buffer or text IO and returns it.
4886
Mark Dickinson33841c32009-05-01 15:37:04 +00004887- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4888 floats with absolute value over 1e50. Also remove length
4889 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4890 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004891
Eric Smith741191f2009-05-06 13:08:15 +00004892- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004893 format(complex(1, 2./3), '.5') now produces a sensible result.
4894
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004895- Issue #5864: Fix empty format code formatting for floats so that it
4896 never gives more than the requested number of significant digits.
4897
Eric Smith6dc46f52009-04-27 20:39:49 +00004898- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4899 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4900
Eric Smithcc32a112009-04-26 21:35:14 +00004901- Issue #5835: Deprecate PyOS_ascii_formatd.
4902
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004903- Issue #4971: Fix titlecase for characters that are their own
4904 titlecase, but not their own uppercase.
4905
Benjamin Peterson193152c2009-04-25 01:08:45 +00004906- Issue #5283: Setting __class__ in __del__ caused a segfault.
4907
Mark Dickinsonad476da2009-04-23 19:14:16 +00004908- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4909 z involves nans, infs or negative zeros.
4910
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004911- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004912
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004913- Issue #1869 (and many duplicates): make round(x, n) correctly
4914 rounded for a float x, by using the decimal <-> binary conversions
4915 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4916 consistently agrees with format(x, '.2f').
4917
Benjamin Petersonae937c02009-04-18 20:54:08 +00004918- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4919 some builtin types.
4920
Eric Smith0923d1d2009-04-16 20:16:10 +00004921- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4922
Eric Smith35e84722009-04-16 20:21:28 +00004923- Issue #5515: str.format() type 'n' combined with commas and leading
4924 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004925
4926- Implement PEP 378, Format Specifier for Thousands Separator, for
4927 floats.
4928
Mark Dickinson3370cce2009-04-17 22:40:53 +00004929- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004930 1e11, not 1e12. This avoids printing 13 significant digits in
4931 situations where only 12 of them are correct. Example problem
4932 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4933 long time.)
4934
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004935- Issue #1580: On most platforms, use a 'short' float repr: for a
4936 finite float x, repr(x) now outputs a string based on the shortest
4937 sequence of decimal digits that rounds to x. Previous behaviour was
4938 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004939 Another minor difference is that the new repr switches to
4940 exponential notation at 1e16 instead of the previous 1e17; this
4941 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004942
4943 There's a new sys attribute sys.float_repr_style, which takes
4944 the value 'short' to indicate that we're using short float repr,
4945 and 'legacy' if the short float repr isn't available for one
4946 reason or another.
4947
4948 The float repr change involves incorporating David Gay's 'perfect
4949 rounding' code into the Python core (it's in Python/dtoa.c). As a
4950 secondary consequence, all string-to-float and float-to-string
4951 conversions (including all float formatting operations) will be
4952 correctly rounded on these platforms.
4953
Georg Brandl5f90d792010-08-01 22:31:05 +00004954 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004955 this change does not apply.
4956
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004957- Issue #5759: float() didn't call __float__ on str subclasses.
4958
Georg Brandlabc38772009-04-12 15:51:51 +00004959- The string.maketrans() function is deprecated; there is a new static method
4960 maketrans() on the bytes and bytearray classes. This removes confusion about
4961 the types string.maketrans() is supposed to work with, and mirrors the
4962 methods available on the str class.
4963
R. David Murraydc6da8a2009-04-09 22:16:43 +00004964- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4965 its clarity and its speed.
4966
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004967- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004968 to avoid compiler warnings.
4969
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004970- Issue #3739: The unicode-internal encoder now reports the number of characters
4971 consumed like any other encoder (instead of the number of bytes).

5149
Eric Smith8ec90442009-03-14 12:29:34 +00005150- Issue #5237: Allow auto-numbered fields in str.format(). For

5302 to an integer. Only the __int__ and __trunc__ slots are examined.

5307
Antoine Pitrouab868312009-01-10 15:40:25 +00005308- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5309 common cases are optimized thanks to a dedicated fast path and a moderate
5310 amount of loop unrolling.
5311
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005312- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5313 collecting the oldest generation) so that allocating lots of objects without
5314 destroying them does not show quadratic performance. Based on a proposal by
5315 Martin von Löwis at
5316 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5317
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005318- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005319 having been closed (for instance, a read() call could return some
5320 previously buffered data). Patch by Dmitry Vasiliev.
5321
Antoine Pitrou05608432009-01-09 18:53:14 +00005322- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5323 flag to work properly. Furthermore, when specifying -u, the text stdout
5324 and stderr streams have line-by-line buffering enabled (the default being
5325 to buffer arbitrary chunks of data).
5326
Raymond Hettinger35631532009-01-09 03:58:09 +00005327- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5328 instead of ints (reducing its size from 4 to 8 times thereby reducing
5329 Python's overall memory).
5330
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005331- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5332 an existing .py counterpart, override the co_filename attributes of all
5333 code objects if the original filename is obsolete (which can happen if the
5334 file has been renamed, moved, or if it is accessed through different paths).
5335 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5336
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005337- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5338 one byte. Also fixes the meaning of len() so that it returns the number of
5339 items, rather than the size in bytes.
5340
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005341- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005343- Issue #4747: When the terminal does not use utf-8, executing a script with

5345
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005346- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5351
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005352- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5353 where the tp_hash and tp_dict slots are both NULL.
5354
Georg Brandlccc47b62008-12-28 11:44:14 +00005355- Issue #4759: None is now allowed as the first argument of
5356 bytearray.translate(). It was always allowed for bytes.translate().
5357
Skip Montanaro80072cb2008-12-23 03:51:14 +00005358- Added test case to ensure attempts to read from a file opened for writing
5359 fail.

5365
Antoine Pitrou621601a2008-12-17 23:18:19 +00005366- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5374 failures on OS X.
5375
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005376- Issue #4597: Fixed several opcodes that weren't always propagating

5378
5379- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005380 context manager returns a value that cannot be converted to a bool.
5381
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005382- Issue #4445: Replace "sizeof(PyBytesObject)" with
5383 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5384 bytes instances. On a typical machine this saves 3 bytes of memory
5385 (on average) per allocation of a bytes instance.
5386
Christian Heimesa872de52008-12-05 08:26:55 +00005387- Issue #4533: File read operation was dreadfully slow due to a slowly
5388 growing read buffer. Fixed by using the same growth rate algorithm as
5389 Python 2.x.
5390
Antoine Pitrou5504e892008-12-06 21:27:53 +00005391- Issue #4509: Various issues surrounding resize of bytearray objects to
5392 which there are buffer exports (e.g. memoryview instances).
5393
Georg Brandlf9734072008-12-07 15:30:06 +00005394- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5395 method on file objects with closefd=False. The file descriptor is still
5396 kept open but the file object behaves like a closed file. The ``FileIO``
5397 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005399- Issue #4569: Interpreter crash when mutating a memoryview with an item size

5405
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005406- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5407 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5408 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5409 of using the replace error handler in PyUnicode_DecodeUTF8().
