Charles-François Natali778db492011-07-02 14:35:49 +020042- Issue #12352: Fix a deadlock in multiprocessing.Heap when a block is freed by
43 the garbage collector while the Heap lock is held.
44

46 UTF-8 instead of the locale encoding if the encoding is not specified. It now
47 also opens XML files for the parser in binary mode instead of the text mode
48 to avoid encoding issues.

Ned Deily657b2de2011-06-28 19:51:30 -070059- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
60 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
61 interpreter process. This could cause failures in non-Distutils subprocesses
62 and was unreliable since tests or user programs could modify the interpreter
63 environment after Distutils set it. Instead, have Distutils set the the
64 deployment target only in the environment of each build subprocess. It is
65 still possible to globally override the default by setting
66 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
67 greater or equal to the default value, the value with which the interpreter
68 was built.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00001564 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001565 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

1908-----------------
1909
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001910- Issue #10068: Global objects which have reference cycles with their module's
1911 dict are now cleared again. This causes issue #7140 to appear again.
1912
Victor Stinner257d38f2010-10-09 10:12:11 +00001913- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001914 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001915
Georg Brandl27a28582010-10-10 09:49:21 +00001916- ast.literal_eval() can now handle negative numbers. It is also a little more
1917 liberal in what it accepts without compromising the safety of the evaluation.
1918 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001919
Benjamin Peterson970d1882010-10-02 17:55:47 +00001920- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1921 result metaclasses can now be ABCs (see #9533).
1922
Victor Stinneraef57e32010-10-02 11:50:49 +00001923- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1924
Victor Stinner5593d8a2010-10-02 11:11:27 +00001925- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001926 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
1927 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00001928
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001929- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00001930 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001931
Victor Stinner137c34c2010-09-29 10:25:54 +00001932- Issue #9979: Create function PyUnicode_AsWideCharString().
1933
Brett Cannon5305a992010-09-27 21:08:38 +00001934- Issue #7397: Mention that importlib.import_module() is probably what someone
1935 really wants to be using in __import__'s docstring.
1936
Georg Brandl27a28582010-10-10 09:49:21 +00001937- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1938 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00001939
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001940- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001941 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001942
Brian Curtine8e4b3b2010-09-23 20:04:14 +00001943- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1944
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001945- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1946 threads are still running. Instead, reinitialize the GIL on a second call to
1947 Py_Initialize().
1948
Georg Brandl27a28582010-10-10 09:49:21 +00001949- All SyntaxErrors now have a column offset and therefore a caret when the error
1950 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001951
Brett Cannonbc2eff32010-09-19 21:39:02 +00001952- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1953 module that was imported, but instead gets the module from sys.modules.
1954
Nick Coghlan37ee8502010-12-03 14:26:13 +00001955- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001956 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001957
Georg Brandl27a28582010-10-10 09:49:21 +00001958- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1959 with a non-empty format string. This is an effort to future-proof user
1960 code. If a derived class does not currently implement __format__ but later
1961 adds its own __format__, it would most likely break user code that had
1962 supplied a format string. This will be changed to a DeprecationWaring in
1963 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001964
Antoine Pitrou1df15362010-09-13 14:16:46 +00001965- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1966 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1967 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1968
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001969- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1970 functions from the libc caused the methods .upper() and lower() to become
1971 locale aware and created subtly wrong results.
1972
Georg Brandl27a28582010-10-10 09:49:21 +00001973- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1974 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001975
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001976- Issue #4617: Previously it was illegal to delete a name from the local
1977 namespace if it occurs as a free variable in a nested block. This limitation
1978 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1979
Georg Brandl27a28582010-10-10 09:49:21 +00001980- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1981 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1982 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1983 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001984
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001985- Issue #9757: memoryview objects get a release() method to release the
1986 underlying buffer (previously this was only done when deallocating the
1987 memoryview), and gain support for the context management protocol.
1988
Antoine Pitrou079ce542010-09-08 12:37:10 +00001989- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1990 thread-local storage key.

2002 not in build_clib.
2003
Antoine Pitroudbec7802010-10-10 09:37:12 +00002004- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2005
R. David Murray96fd54e2010-10-08 15:55:28 +00002006- Issue #4661: email can now parse bytes input and generate either converted
2007 7bit output or bytes output. Email version bumped to 5.1.0.
2008
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002009- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2010 verification for higher-level protocols.
2011
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002012- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2013 after the file is closed. Patch by Jeffrey Finkelstein.
2014
Éric Araujo6108bf52010-10-04 23:52:37 +00002015- Issue #9042: Fix interaction of custom translation classes and caching in
2016 gettext.
2017
Éric Araujoef777bd2010-10-05 00:04:20 +00002018- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002019 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002020 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002021 replacement for old handle_accept() and avoids the user to call accept()
2022 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002024- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002029
R. David Murray5397e862010-10-02 15:58:26 +00002030- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2031 characters that appear inside quoted strings in email addresses.

Georg Brandl27a28582010-10-10 09:49:21 +00002033- Issue #10004: quoprimime no longer generates a traceback when confronted with

2040 conforms to the philosophy of bytes and unicode separation in Python 3. A
2041 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002043- Issue #9962: GzipFile now has the peek() method.
2044
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002045- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002046 retry the select() loop instead of bailing out. This is because select() can
2047 incorrectly report a socket as ready for reading (for example, if it received
2048 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002131 approach of using weakref proxies so that reference cycles never get created
2132 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002134- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2135 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002136 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002138- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2139 environment variable to set the filesystem encoding at Python startup.
2140 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2141 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002143- Issue #9410: Various optimizations to the pickle module, leading to speedups
2144 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2145 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002146
Georg Brandl27a28582010-10-10 09:49:21 +00002147- The pprint module now supports printing OrderedDicts in their given order
2148 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002149
Vinay Sajip121a1c42010-09-08 10:46:15 +00002150- Logging: Added QueueHandler class to facilitate logging usage with
2151 multiprocessing.
2152
Georg Brandl27a28582010-10-10 09:49:21 +00002153- Issue #9707: Rewritten reference implementation of threading.local which is
2154 friendlier towards reference cycles. This change is not normally visible
2155 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002156
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002157- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2158 still return the id of the parent process after it has exited. This process
2159 id may even have been reused by another unrelated process.
2160
Georg Brandl27a28582010-10-10 09:49:21 +00002161- Issue #9792: In case of connection failure, socket.create_connection() would
2162 swallow the exception and raise a new one, making it impossible to fetch the
2163 original errno, or to filter timeout errors. Now the original error is
2164 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002166- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2167 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2168 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002170- Updates to the random module:
2171
Georg Brandl27a28582010-10-10 09:49:21 +00002172 * Document which parts of the module are guaranteed to stay the same across
2173 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002174
Georg Brandl27a28582010-10-10 09:49:21 +00002175 * Update the seed() method to use all of the bits in a string instead of just
2176 the hash value. This makes better use of the seed value and assures the
2177 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002178
Georg Brandl27a28582010-10-10 09:49:21 +00002179 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2180 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2181 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002182
2183 * Improved documentation of arguments to randrange(). Issue #9379.

2189 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2190 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002191
Georg Brandl27a28582010-10-10 09:49:21 +00002192- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2193 their contents without duplicating them. The view is both readable and
2194 writable.

2197
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002198- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002199 unsupported operation is attempted (for example, writing to a file open only
2200 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002202- hashlib has two new constant attributes: algorithms_guaranteed and
2203 algorithms_avaiable that respectively list the names of hash algorithms
2204 guaranteed to exist in all Python implementations and the names of hash
2205 algorithms available in the current process.
2206
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002207- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002310- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2311 now removed, since their effect was inexistent in 3.x (the default encoding is

2334 return characters from the full Unicode range, even on narrow unicode builds
2335 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2336 in Python is that unicodedata.numeric() now returns the correct value for
2337 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002374- Issue #9416: Fix some issues with complex formatting where the output with no
2375 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002376
2377 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00002717- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002718 start byte and the continuation byte(s) are now considered invalid, instead of
2719 the number of bytes specified by the start byte. E.g.:
2720 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2721 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2722 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2723 returned a single u'\ufffd'.

2738 dealing with unary minus applied to a constant. The removed code was mutating
2739 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00002743 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002744 handlers. Patch written by Mark Hammond.

Victor Stinner25e8ec42010-06-25 00:02:38 +00002746- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2747 "w*" format instead. Add tests for "w*" format.
2748
Victor Stinner06e49dd2010-06-13 18:21:50 +00002749- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002750 formats if the string contains a null byte/character. Write unit tests for

2752
Georg Brandl62069d32010-07-31 08:56:11 +00002753- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002754 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2755 location of the raised exception.
2756
Victor Stinner313a1202010-06-11 23:56:51 +00002757- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2758 filenames and enable os.fsencode().
2759

2761
Georg Brandl62069d32010-07-31 08:56:11 +00002762- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2763 interpreter with characters outside the Basic Multilingual Plane (higher than
2764 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002765
Georg Brandl62069d32010-07-31 08:56:11 +00002766- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2767 TypeError instead of giving a DeprecationWarning when a float is parsed using
2768 the 'L' code (for long long). (All other integer codes already raise
2769 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002770
Victor Stinner600d3be2010-06-10 12:00:55 +00002771- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2772 enable shortcuts for upper case encoding name. Add also a shortcut for
2773 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2774
Georg Brandl62069d32010-07-31 08:56:11 +00002775- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2776 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002777
2778- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002779 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002780 like bytearray.
2781
Georg Brandl62069d32010-07-31 08:56:11 +00002782- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002783 used anymore and it was never documented.
2784
Georg Brandl62069d32010-07-31 08:56:11 +00002785- In str.format(), raise a ValueError when indexes to arguments are too large.

2788 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002789
Georg Brandl62069d32010-07-31 08:56:11 +00002790- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2791 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2792 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2793 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002794
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002795- Issue #8748: Fix two issues with comparisons between complex and integer
2796 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002797 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2798 (2) The comparison raised an OverflowError for large integers, leading to
2799 unpredictable exceptions when combining integers and complex objects in sets
2800 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002801

2804
Victor Stinner9ca9c252010-05-19 16:53:30 +00002805- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002806 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002807 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002808
Georg Brandl62069d32010-07-31 08:56:11 +00002809- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2810 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002811
Victor Stinnerae6265f2010-05-15 16:27:27 +00002812- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2813 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002814 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002815 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002816
Victor Stinner59e62db2010-05-15 13:14:32 +00002817- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002818 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002819
Victor Stinnerb744ba12010-05-15 12:27:16 +00002820- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002821 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002822 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2823
Victor Stinner0964ee12010-04-30 16:48:45 +00002824- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002825 PyUnicode_FromString() to support surrogates in the filename and use the right
2826 encoding.

Georg Brandl62069d32010-07-31 08:56:11 +00003239 applications that use a lot of regular expressions and limits the impact of
3240 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003532- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3533 the method could block indefinitely if called just before the event loop
3534 started running. This also fixes the occasional freezes witnessed in
3535 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00003537- Issue #8524: When creating an SSL socket, the timeout value of the original
3538 socket wasn't retained (instead, a socket with a positive timeout would be
3539 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003540
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003541- Issue #5103: SSL handshake would ignore the socket timeout and block
3542 indefinitely if the other end didn't respond.
3543
Georg Brandl62069d32010-07-31 08:56:11 +00003544- The do_handshake() method of SSL objects now adjusts the blocking mode of the
3545 SSL structure if necessary (as other methods already do).

3557 string "python" as the *ident*. openlog() arguments are all optional and
3558 keywords.

Georg Brandl62069d32010-07-31 08:56:11 +00003560- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3561 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003562 wanting to continue using the socket in clear-text mode, by disabling

3611
Georg Brandl62069d32010-07-31 08:56:11 +00003612- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003613 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003614 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003638- Add functools.total_ordering() and functools.cmp_to_key().
3639
Georg Brandl62069d32010-07-31 08:56:11 +00003640- Issue #8257: The Decimal construct now accepts a float instance directly,
3641 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003642
3643 >>> Decimal(1.1)
3644 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003649- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3650 InvalidOperation instead of returning False. (Comparisons involving a quiet
3651 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3652 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003653
Georg Brandl62069d32010-07-31 08:56:11 +00003654- Issue #2531: Comparison operations between floats and Decimal instances now
3655 return a result based on the numeric values of the operands; previously they
3656 returned an arbitrary result based on the relative ordering of id(float) and
3657 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3658 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003659
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003660- Added a subtract() method to collections.Counter().
3661
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003662- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003663 argument `-` which tells it to read files to compile from stdin. Each line is
3664 read on demand and the named file is compiled immediately. (Original patch by
3665 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003667- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3668 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003669 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00003671- Comparisons using one of <, <=, >, >= between a complex instance and a
3672 Fractions instance now raise TypeError instead of returning True/False. This
3673 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3674 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003684 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00003717- The internals of the subprocess module on POSIX systems have been replaced by
3718 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3719 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003721- subprocess.Popen now has restore_signals and start_new_session features. The
3722 default of restore_signals=True is a new behavior compared to earlier Python
3723 versions. This means that signals such as SIGPIPE are not ignored by default
3724 in subprocesses launched by Python (Issue #1652).

4002 locks as fast as regular non-recursive locks (previously, they were slower by

4252 directive. When the ``%z`` directive is present in the format string, an
4253 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4254 ``datetime.timezone`` instance constructed from the parsed offset. If both
4255 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4256 name, but ``%Z`` data without ``%z`` is discarded.

4260 ``datetime.timezone``, return fixed name and UTC offset from their
4261 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4262 returns ``None``. A class attribute, ``utc`` contains an instance
4263 representing the UTC timezone. Original patch by Rafe Kaplan.

4741
Eric Smith41669ca2009-05-23 14:23:22 +00004742- Issue #6089: Fixed str.format with certain invalid field specifiers
4743 that would raise SystemError.
4744
Raymond Hettinger2bcde142009-05-29 04:52:27 +00004745- Issue #5982: staticmethod and classmethod now expose the wrapped
4746 function with __func__.
4747
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00004748- Added support for multiple context managers in the same with-statement.
4749 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00004751- Issue #5829: complex("1e500") no longer raises OverflowError. This
4752 makes it consistent with float("1e500") and interpretation of real
4753 and imaginary literals.
4754
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00004755- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00004759- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
4760 (1) inf and nan strings with trailing whitespace were incorrectly
4761 rejected; (2) parsing of strings representing infinities and nans
4762 was locale aware; and (3) the interpretation of fromhex('-nan')
4763 didn't match that of float('-nan').

4779 names: cls, self, tuple, itemgetter, and property.
4780
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004781- In unittest, using a skipping decorator on a class is now equivalent to
4782 skipping every test on the class. The ClassTestSuite class has been removed.
4783
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004784- Issue #6050: Don't fail extracting a directory from a zipfile if
4785 the directory already exists.
4786
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004787- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4788 than an int, which makes some operations possible under 64-bit Linux (e.g.
4789 DN_MULTISHOT with F_NOTIFY).
4790
Antoine Pitrou716c4442009-05-23 19:04:03 +00004791- Issue #5761: Add the name of the underlying file to the repr() of various
4792 IO objects.
4793
R. David Murraycaa27b72009-05-23 18:49:56 +00004794- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4795 by Musashi Tamura, tests by Marcin Bachry.
4796
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004797- Issue #1983: Fix functions taking or returning a process identifier to use
4798 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4799 a process identifier type wider than the standard C integer type.
4800
R. David Murray87e20742009-05-23 01:30:26 +00004801- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

4812
Antoine Pitroue4501852009-05-14 18:55:55 +00004813- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4814 library. This means, for example, that opening an UTF-16 text file in
4815 append mode doesn't add a BOM at the end of the file if the file isn't
4816 empty.
4817
R. David Murray74b89242009-05-13 17:33:03 +00004818- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4819 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4820 corrects a pydoc regression.
4821
Georg Brandl5f90d792010-08-01 22:31:05 +00004822- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004823 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004861What's New in Python 3.1 beta 1?
4862================================
4863
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004864*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004865
4866Core and Builtins
4867-----------------
4868
Mark Dickinson865e01a2009-05-07 16:37:01 +00004869- Issue #5914: Add new C API function PyOS_string_to_double, and
4870 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4871
Eric Smith741191f2009-05-06 13:08:15 +00004872- Issue #3382: float.__format__, complex.__format__, and %-formatting
4873 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4874 affects nan -> NAN and inf -> INF.
4875
Mark Hammond5a607a32009-05-06 08:04:54 +00004876- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4877 in all operations, including splitdrive, split, etc. splitunc() now issues
4878 a PendingDeprecation warning.
4879
Eric Smith63376222009-05-05 14:04:18 +00004880- Issue #5920: For float.__format__, change the behavior with the
4881 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4882 to be like 'g' but with at least one decimal point and with a
4883 default precision of 12. Previously, the behavior the same but with
4884 a default precision of 6. This more closely matches str(), and
4885 reduces surprises when adding alignment flags to the empty
4886 presentation type. This also affects the new complex.__format__ in
4887 the same way.
4888
Martin v. Löwis011e8422009-05-05 04:43:17 +00004889- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4890
R. David Murrayb18500d2009-05-04 22:59:07 +00004891- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4892 shadowed by classtype's, even if it was None. property now
4893 inserts the __doc__ into the subclass instance __dict__.
4894
Antoine Pitrou244651a2009-05-04 18:56:13 +00004895- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4896 sequences. Patch by Nick Barnes and Victor Stinner.
4897
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004898- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004899
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004900- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4901 received a new method, detach(). detach() disconnects the underlying stream
4902 from the buffer or text IO and returns it.
4903
Mark Dickinson33841c32009-05-01 15:37:04 +00004904- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4905 floats with absolute value over 1e50. Also remove length
4906 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4907 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004908
Eric Smith741191f2009-05-06 13:08:15 +00004909- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004910 format(complex(1, 2./3), '.5') now produces a sensible result.
4911
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004912- Issue #5864: Fix empty format code formatting for floats so that it
4913 never gives more than the requested number of significant digits.
4914
Eric Smith6dc46f52009-04-27 20:39:49 +00004915- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4916 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4917
Eric Smithcc32a112009-04-26 21:35:14 +00004918- Issue #5835: Deprecate PyOS_ascii_formatd.
4919
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004920- Issue #4971: Fix titlecase for characters that are their own
4921 titlecase, but not their own uppercase.
4922
Benjamin Peterson193152c2009-04-25 01:08:45 +00004923- Issue #5283: Setting __class__ in __del__ caused a segfault.
4924
Mark Dickinsonad476da2009-04-23 19:14:16 +00004925- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4926 z involves nans, infs or negative zeros.
4927
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004928- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004929
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004930- Issue #1869 (and many duplicates): make round(x, n) correctly
4931 rounded for a float x, by using the decimal <-> binary conversions
4932 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4933 consistently agrees with format(x, '.2f').
4934
Benjamin Petersonae937c02009-04-18 20:54:08 +00004935- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4936 some builtin types.
4937
Eric Smith0923d1d2009-04-16 20:16:10 +00004938- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4939
Eric Smith35e84722009-04-16 20:21:28 +00004940- Issue #5515: str.format() type 'n' combined with commas and leading
4941 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004942
4943- Implement PEP 378, Format Specifier for Thousands Separator, for
4944 floats.
4945
Mark Dickinson3370cce2009-04-17 22:40:53 +00004946- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004947 1e11, not 1e12. This avoids printing 13 significant digits in
4948 situations where only 12 of them are correct. Example problem
4949 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4950 long time.)
4951
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004952- Issue #1580: On most platforms, use a 'short' float repr: for a
4953 finite float x, repr(x) now outputs a string based on the shortest
4954 sequence of decimal digits that rounds to x. Previous behaviour was
4955 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004956 Another minor difference is that the new repr switches to
4957 exponential notation at 1e16 instead of the previous 1e17; this
4958 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004959
4960 There's a new sys attribute sys.float_repr_style, which takes
4961 the value 'short' to indicate that we're using short float repr,
4962 and 'legacy' if the short float repr isn't available for one
4963 reason or another.
4964
4965 The float repr change involves incorporating David Gay's 'perfect
4966 rounding' code into the Python core (it's in Python/dtoa.c). As a
4967 secondary consequence, all string-to-float and float-to-string
4968 conversions (including all float formatting operations) will be
4969 correctly rounded on these platforms.
4970
Georg Brandl5f90d792010-08-01 22:31:05 +00004971 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004972 this change does not apply.
4973
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004974- Issue #5759: float() didn't call __float__ on str subclasses.
4975
Georg Brandlabc38772009-04-12 15:51:51 +00004976- The string.maketrans() function is deprecated; there is a new static method
4977 maketrans() on the bytes and bytearray classes. This removes confusion about
4978 the types string.maketrans() is supposed to work with, and mirrors the
4979 methods available on the str class.
4980
R. David Murraydc6da8a2009-04-09 22:16:43 +00004981- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4982 its clarity and its speed.
4983
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004984- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004985 to avoid compiler warnings.
4986
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004987- Issue #3739: The unicode-internal encoder now reports the number of characters
4988 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005304- Issue #4838: When a module is deallocated, free the memory backing the
5305 optional module state data.
5306
Mark Dickinson8055afd2009-01-17 10:04:45 +00005307- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005308 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005309
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005310- Issue #4935: The overflow checking code in the expandtabs() method common
5311 to str, bytes and bytearray could be optimized away by the compiler, letting
5312 the interpreter segfault instead of raising an error.
5313
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005314- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5315 __next__ method.
5316
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005317- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5318 function no longer attempt to call the __long__ slot to convert an object
5319 to an integer. Only the __int__ and __trunc__ slots are examined.

5324
Antoine Pitrouab868312009-01-10 15:40:25 +00005325- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5326 common cases are optimized thanks to a dedicated fast path and a moderate
5327 amount of loop unrolling.
5328
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005329- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5330 collecting the oldest generation) so that allocating lots of objects without
5331 destroying them does not show quadratic performance. Based on a proposal by
5332 Martin von Löwis at
5333 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5334
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005335- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005336 having been closed (for instance, a read() call could return some
5337 previously buffered data). Patch by Dmitry Vasiliev.
5338
Antoine Pitrou05608432009-01-09 18:53:14 +00005339- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5340 flag to work properly. Furthermore, when specifying -u, the text stdout
5341 and stderr streams have line-by-line buffering enabled (the default being
5342 to buffer arbitrary chunks of data).
5343
Raymond Hettinger35631532009-01-09 03:58:09 +00005344- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5345 instead of ints (reducing its size from 4 to 8 times thereby reducing
5346 Python's overall memory).
5347
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005348- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5349 an existing .py counterpart, override the co_filename attributes of all
5350 code objects if the original filename is obsolete (which can happen if the
5351 file has been renamed, moved, or if it is accessed through different paths).
5352 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5353
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005354- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5355 one byte. Also fixes the meaning of len() so that it returns the number of
5356 items, rather than the size in bytes.
5357
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005358- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005360- Issue #4747: When the terminal does not use utf-8, executing a script with

5362
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005363- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5368
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005369- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5370 where the tp_hash and tp_dict slots are both NULL.
5371
Georg Brandlccc47b62008-12-28 11:44:14 +00005372- Issue #4759: None is now allowed as the first argument of

5374
Skip Montanaro80072cb2008-12-23 03:51:14 +00005375- Added test case to ensure attempts to read from a file opened for writing
5376 fail.

5382
Antoine Pitrou621601a2008-12-17 23:18:19 +00005383- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5391 failures on OS X.
5392
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005393- Issue #4597: Fixed several opcodes that weren't always propagating

5395
5396- Issue #4589: Fixed exception handling when the __exit__ function of a

5398
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005399- Issue #4445: Replace "sizeof(PyBytesObject)" with
5400 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5401 bytes instances. On a typical machine this saves 3 bytes of memory
5402 (on average) per allocation of a bytes instance.
5403
Christian Heimesa872de52008-12-05 08:26:55 +00005404- Issue #4533: File read operation was dreadfully slow due to a slowly
5405 growing read buffer. Fixed by using the same growth rate algorithm as
5406 Python 2.x.
5407
Antoine Pitrou5504e892008-12-06 21:27:53 +00005408- Issue #4509: Various issues surrounding resize of bytearray objects to
5409 which there are buffer exports (e.g. memoryview instances).
5410
Georg Brandlf9734072008-12-07 15:30:06 +00005411- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5412 method on file objects with closefd=False. The file descriptor is still
5413 kept open but the file object behaves like a closed file. The ``FileIO``
5414 object also got a new readonly attribute ``closefd``.

5422
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005423- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5424 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5425 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5426 of using the replace error handler in PyUnicode_DecodeUTF8().

5852 from inside a module loaded via a PEP 302 loader and attempting to
5853 perform IO operations based on __file__). Original patch by
5854 Alexander Belopolsky.
5855
5856- Issues #4082 and #4512: Add runpy support to zipimport in a manner that
