Ned Deily657b2de2011-06-28 19:51:30 -0700513- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
514 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
515 interpreter process. This could cause failures in non-Distutils subprocesses
516 and was unreliable since tests or user programs could modify the interpreter
517 environment after Distutils set it. Instead, have Distutils set the the
518 deployment target only in the environment of each build subprocess. It is
519 still possible to globally override the default by setting
520 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
521 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700522 was built. Also, implement the same handling in packaging.

1715 is made for all headers in any serialized message at serialization time. This
1716 provides protection against header injection attacks.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002372 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2716
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002717- Issue #10068: Global objects which have reference cycles with their module's
2718 dict are now cleared again. This causes issue #7140 to appear again.
2719
Victor Stinner257d38f2010-10-09 10:12:11 +00002720- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002721 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002722
Georg Brandl27a28582010-10-10 09:49:21 +00002723- ast.literal_eval() can now handle negative numbers. It is also a little more
2724 liberal in what it accepts without compromising the safety of the evaluation.
2725 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002726
Benjamin Peterson970d1882010-10-02 17:55:47 +00002727- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2728 result metaclasses can now be ABCs (see #9533).
2729
Victor Stinneraef57e32010-10-02 11:50:49 +00002730- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2731
Victor Stinner5593d8a2010-10-02 11:11:27 +00002732- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002733 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2734 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002735
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002736- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002737 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002738
Victor Stinner137c34c2010-09-29 10:25:54 +00002739- Issue #9979: Create function PyUnicode_AsWideCharString().
2740
Brett Cannon5305a992010-09-27 21:08:38 +00002741- Issue #7397: Mention that importlib.import_module() is probably what someone
2742 really wants to be using in __import__'s docstring.
2743
Georg Brandl27a28582010-10-10 09:49:21 +00002744- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2745 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002746
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002747- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002748 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002749
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002750- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2751
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002752- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2753 threads are still running. Instead, reinitialize the GIL on a second call to
2754 Py_Initialize().
2755
Georg Brandl27a28582010-10-10 09:49:21 +00002756- All SyntaxErrors now have a column offset and therefore a caret when the error
2757 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002758
Brett Cannonbc2eff32010-09-19 21:39:02 +00002759- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2760 module that was imported, but instead gets the module from sys.modules.
2761
Nick Coghlan37ee8502010-12-03 14:26:13 +00002762- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002763 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002764
Georg Brandl27a28582010-10-10 09:49:21 +00002765- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2766 with a non-empty format string. This is an effort to future-proof user
2767 code. If a derived class does not currently implement __format__ but later
2768 adds its own __format__, it would most likely break user code that had
2769 supplied a format string. This will be changed to a DeprecationWaring in
2770 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002771
Antoine Pitrou1df15362010-09-13 14:16:46 +00002772- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2773 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2774 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2775
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002776- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2777 functions from the libc caused the methods .upper() and lower() to become
2778 locale aware and created subtly wrong results.
2779
Georg Brandl27a28582010-10-10 09:49:21 +00002780- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2781 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002782
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002783- Issue #4617: Previously it was illegal to delete a name from the local
2784 namespace if it occurs as a free variable in a nested block. This limitation
2785 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2786
Georg Brandl27a28582010-10-10 09:49:21 +00002787- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2788 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2789 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2790 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002791
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002792- Issue #9757: memoryview objects get a release() method to release the
2793 underlying buffer (previously this was only done when deallocating the
2794 memoryview), and gain support for the context management protocol.
2795
Antoine Pitrou079ce542010-09-08 12:37:10 +00002796- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2797 thread-local storage key.

2809 not in build_clib.
2810
Antoine Pitroudbec7802010-10-10 09:37:12 +00002811- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2812
R. David Murray96fd54e2010-10-08 15:55:28 +00002813- Issue #4661: email can now parse bytes input and generate either converted
2814 7bit output or bytes output. Email version bumped to 5.1.0.
2815
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002816- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2817 verification for higher-level protocols.
2818
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002819- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2820 after the file is closed. Patch by Jeffrey Finkelstein.
2821
Éric Araujo6108bf52010-10-04 23:52:37 +00002822- Issue #9042: Fix interaction of custom translation classes and caching in
2823 gettext.
2824
Éric Araujoef777bd2010-10-05 00:04:20 +00002825- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002826 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002827 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002828 replacement for old handle_accept() and avoids the user to call accept()
2829 directly.
2830
Lars Gustäbel331b8002010-10-04 15:18:47 +00002831- Issue #9065: tarfile no longer uses "root" as the default for the uname and

Georg Brandl27a28582010-10-10 09:49:21 +00002834- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2835 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002836
R. David Murray5397e862010-10-02 15:58:26 +00002837- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2838 characters that appear inside quoted strings in email addresses.
2839
Georg Brandl27a28582010-10-10 09:49:21 +00002840- Issue #10004: quoprimime no longer generates a traceback when confronted with
2841 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002842
Georg Brandl27a28582010-10-10 09:49:21 +00002843- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2844 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002845

2847 conforms to the philosophy of bytes and unicode separation in Python 3. A
2848 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002850- Issue #9962: GzipFile now has the peek() method.
2851
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002852- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002853 retry the select() loop instead of bailing out. This is because select() can
2854 incorrectly report a socket as ready for reading (for example, if it received
2855 some data with an invalid checksum).

Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002857- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00002859- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002860 received. Now sendall() properly calls signal handlers if necessary, and
2861 retries sending if these returned successfully, including on sockets with a

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002938 approach of using weakref proxies so that reference cycles never get created
2939 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00002941- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2942 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002943 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +00002945- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2946 environment variable to set the filesystem encoding at Python startup.
2947 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2948 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002950- Issue #9410: Various optimizations to the pickle module, leading to speedups
2951 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2952 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002953
Georg Brandl27a28582010-10-10 09:49:21 +00002954- The pprint module now supports printing OrderedDicts in their given order
2955 (formerly, it would sort the keys).
Raymond Hettingerbad3c882010-09-09 12:31:00 +00002956
Vinay Sajip121a1c42010-09-08 10:46:15 +00002957- Logging: Added QueueHandler class to facilitate logging usage with
2958 multiprocessing.
2959
Georg Brandl27a28582010-10-10 09:49:21 +00002960- Issue #9707: Rewritten reference implementation of threading.local which is
2961 friendlier towards reference cycles. This change is not normally visible
2962 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002963
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002964- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2965 still return the id of the parent process after it has exited. This process
2966 id may even have been reused by another unrelated process.
2967
Georg Brandl27a28582010-10-10 09:49:21 +00002968- Issue #9792: In case of connection failure, socket.create_connection() would
2969 swallow the exception and raise a new one, making it impossible to fetch the
2970 original errno, or to filter timeout errors. Now the original error is
2971 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002973- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2974 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2975 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002977- Updates to the random module:
2978
Georg Brandl27a28582010-10-10 09:49:21 +00002979 * Document which parts of the module are guaranteed to stay the same across
2980 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002981
Georg Brandl27a28582010-10-10 09:49:21 +00002982 * Update the seed() method to use all of the bits in a string instead of just
2983 the hash value. This makes better use of the seed value and assures the
2984 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002985
Georg Brandl27a28582010-10-10 09:49:21 +00002986 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2987 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2988 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002989
2990 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002995- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2996 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2997 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00002998
Georg Brandl27a28582010-10-10 09:49:21 +00002999- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
3000 their contents without duplicating them. The view is both readable and
3001 writable.

3004
Antoine Pitrou0d739d72010-09-05 23:01:12 +00003005- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003006 unsupported operation is attempted (for example, writing to a file open only
3007 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00003009- hashlib has two new constant attributes: algorithms_guaranteed and
3010 algorithms_avaiable that respectively list the names of hash algorithms
3011 guaranteed to exist in all Python implementations and the names of hash
3012 algorithms available in the current process.
3013
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003014- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00003117- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3118 now removed, since their effect was inexistent in 3.x (the default encoding is

3141 return characters from the full Unicode range, even on narrow unicode builds
3142 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3143 in Python is that unicodedata.numeric() now returns the correct value for
3144 large code points, and repr() may consider more characters as printable.
3145
Victor Stinner6c00c142010-08-17 23:37:11 +00003146- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003181- Issue #9416: Fix some issues with complex formatting where the output with no
3182 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003183
3184 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003524- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003525 start byte and the continuation byte(s) are now considered invalid, instead of
3526 the number of bytes specified by the start byte. E.g.:
3527 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3528 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3529 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3530 returned a single u'\ufffd'.

3545 dealing with unary minus applied to a constant. The removed code was mutating
3546 the ST, causing a second compilation to fail.

Georg Brandl62069d32010-07-31 08:56:11 +00003549 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003550 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003551 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003552
Victor Stinner25e8ec42010-06-25 00:02:38 +00003553- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3554 "w*" format instead. Add tests for "w*" format.
3555
Victor Stinner06e49dd2010-06-13 18:21:50 +00003556- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003557 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003558 string formats.
3559
Georg Brandl62069d32010-07-31 08:56:11 +00003560- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003561 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3562 location of the raised exception.
3563
Victor Stinner313a1202010-06-11 23:56:51 +00003564- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3565 filenames and enable os.fsencode().
3566
Benjamin Peterson285a6892010-06-22 19:21:52 +00003567- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3568
Georg Brandl62069d32010-07-31 08:56:11 +00003569- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3570 interpreter with characters outside the Basic Multilingual Plane (higher than
3571 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003572
Georg Brandl62069d32010-07-31 08:56:11 +00003573- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3574 TypeError instead of giving a DeprecationWarning when a float is parsed using
3575 the 'L' code (for long long). (All other integer codes already raise
3576 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003577
Victor Stinner600d3be2010-06-10 12:00:55 +00003578- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3579 enable shortcuts for upper case encoding name. Add also a shortcut for
3580 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3581
Georg Brandl62069d32010-07-31 08:56:11 +00003582- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3583 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003584
3585- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003586 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003587 like bytearray.
3588
Georg Brandl62069d32010-07-31 08:56:11 +00003589- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003590 used anymore and it was never documented.
3591
Georg Brandl62069d32010-07-31 08:56:11 +00003592- In str.format(), raise a ValueError when indexes to arguments are too large.

3595 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003596
Georg Brandl62069d32010-07-31 08:56:11 +00003597- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3598 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3599 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3600 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003601
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003602- Issue #8748: Fix two issues with comparisons between complex and integer
3603 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003604 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3605 (2) The comparison raised an OverflowError for large integers, leading to
3606 unpredictable exceptions when combining integers and complex objects in sets
3607 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003608

3611
Victor Stinner9ca9c252010-05-19 16:53:30 +00003612- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003613 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003614 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003615
Georg Brandl62069d32010-07-31 08:56:11 +00003616- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3617 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003618
Victor Stinnerae6265f2010-05-15 16:27:27 +00003619- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3620 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003621 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003622 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003623
Victor Stinner59e62db2010-05-15 13:14:32 +00003624- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003625 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003626
Victor Stinnerb744ba12010-05-15 12:27:16 +00003627- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003628 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003629 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3630
Victor Stinner0964ee12010-04-30 16:48:45 +00003631- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003632 PyUnicode_FromString() to support surrogates in the filename and use the right
3633 encoding.

Georg Brandl62069d32010-07-31 08:56:11 +00004046 applications that use a lot of regular expressions and limits the impact of
4047 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004339- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4340 the method could block indefinitely if called just before the event loop
4341 started running. This also fixes the occasional freezes witnessed in
4342 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00004344- Issue #8524: When creating an SSL socket, the timeout value of the original
4345 socket wasn't retained (instead, a socket with a positive timeout would be
4346 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004347
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004348- Issue #5103: SSL handshake would ignore the socket timeout and block
4349 indefinitely if the other end didn't respond.
4350
Georg Brandl62069d32010-07-31 08:56:11 +00004351- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4352 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00004367- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4368 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004369 wanting to continue using the socket in clear-text mode, by disabling

4418
Georg Brandl62069d32010-07-31 08:56:11 +00004419- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004420 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004421 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004445- Add functools.total_ordering() and functools.cmp_to_key().
4446
Georg Brandl62069d32010-07-31 08:56:11 +00004447- Issue #8257: The Decimal construct now accepts a float instance directly,
4448 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004449
4450 >>> Decimal(1.1)
4451 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004456- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4457 InvalidOperation instead of returning False. (Comparisons involving a quiet
4458 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4459 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004460
Georg Brandl62069d32010-07-31 08:56:11 +00004461- Issue #2531: Comparison operations between floats and Decimal instances now
4462 return a result based on the numeric values of the operands; previously they
4463 returned an arbitrary result based on the relative ordering of id(float) and
4464 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4465 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004466
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004467- Added a subtract() method to collections.Counter().
4468
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004469- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004470 argument `-` which tells it to read files to compile from stdin. Each line is
4471 read on demand and the named file is compiled immediately. (Original patch by
4472 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004474- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4475 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004476 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004478- Comparisons using one of <, <=, >, >= between a complex instance and a
4479 Fractions instance now raise TypeError instead of returning True/False. This
4480 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4481 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004524- The internals of the subprocess module on POSIX systems have been replaced by
4525 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4526 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004528- subprocess.Popen now has restore_signals and start_new_session features. The
4529 default of restore_signals=True is a new behavior compared to earlier Python
4530 versions. This means that signals such as SIGPIPE are not ignored by default
4531 in subprocesses launched by Python (Issue #1652).

4809 locks as fast as regular non-recursive locks (previously, they were slower by

5059 directive. When the ``%z`` directive is present in the format string, an
5060 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5061 ``datetime.timezone`` instance constructed from the parsed offset. If both
5062 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5063 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005066 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5067 ``datetime.timezone``, return fixed name and UTC offset from their
5068 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5069 returns ``None``. A class attribute, ``utc`` contains an instance
5070 representing the UTC timezone. Original patch by Rafe Kaplan.

5548
Eric Smith41669ca2009-05-23 14:23:22 +00005549- Issue #6089: Fixed str.format with certain invalid field specifiers
5550 that would raise SystemError.
5551
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005552- Issue #5982: staticmethod and classmethod now expose the wrapped
5553 function with __func__.
5554
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005555- Added support for multiple context managers in the same with-statement.
5556 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005558- Issue #5829: complex("1e500") no longer raises OverflowError. This
5559 makes it consistent with float("1e500") and interpretation of real
5560 and imaginary literals.
5561
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005562- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005566- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5567 (1) inf and nan strings with trailing whitespace were incorrectly
5568 rejected; (2) parsing of strings representing infinities and nans
5569 was locale aware; and (3) the interpretation of fromhex('-nan')
5570 didn't match that of float('-nan').

5587
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005588- In unittest, using a skipping decorator on a class is now equivalent to
5589 skipping every test on the class. The ClassTestSuite class has been removed.
5590
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005591- Issue #6050: Don't fail extracting a directory from a zipfile if
5592 the directory already exists.
5593
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005594- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5595 than an int, which makes some operations possible under 64-bit Linux (e.g.
5596 DN_MULTISHOT with F_NOTIFY).
5597
Antoine Pitrou716c4442009-05-23 19:04:03 +00005598- Issue #5761: Add the name of the underlying file to the repr() of various

5600
R. David Murraycaa27b72009-05-23 18:49:56 +00005601- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5602 by Musashi Tamura, tests by Marcin Bachry.
5603
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005604- Issue #1983: Fix functions taking or returning a process identifier to use
5605 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5606 a process identifier type wider than the standard C integer type.
5607
R. David Murray87e20742009-05-23 01:30:26 +00005608- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5619
Antoine Pitroue4501852009-05-14 18:55:55 +00005620- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5621 library. This means, for example, that opening an UTF-16 text file in
5622 append mode doesn't add a BOM at the end of the file if the file isn't
5623 empty.
5624
R. David Murray74b89242009-05-13 17:33:03 +00005625- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5626 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5627 corrects a pydoc regression.
5628
Georg Brandl5f90d792010-08-01 22:31:05 +00005629- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005630 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005671*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005672
5673Core and Builtins
5674-----------------
5675
Mark Dickinson865e01a2009-05-07 16:37:01 +00005676- Issue #5914: Add new C API function PyOS_string_to_double, and
5677 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5678
Eric Smith741191f2009-05-06 13:08:15 +00005679- Issue #3382: float.__format__, complex.__format__, and %-formatting
5680 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5681 affects nan -> NAN and inf -> INF.
5682
Mark Hammond5a607a32009-05-06 08:04:54 +00005683- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5684 in all operations, including splitdrive, split, etc. splitunc() now issues
5685 a PendingDeprecation warning.
5686
Eric Smith63376222009-05-05 14:04:18 +00005687- Issue #5920: For float.__format__, change the behavior with the
5688 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5689 to be like 'g' but with at least one decimal point and with a
5690 default precision of 12. Previously, the behavior the same but with
5691 a default precision of 6. This more closely matches str(), and
5692 reduces surprises when adding alignment flags to the empty
5693 presentation type. This also affects the new complex.__format__ in
5694 the same way.
5695
Martin v. Löwis011e8422009-05-05 04:43:17 +00005696- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5697
R. David Murrayb18500d2009-05-04 22:59:07 +00005698- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5699 shadowed by classtype's, even if it was None. property now
5700 inserts the __doc__ into the subclass instance __dict__.
5701
Antoine Pitrou244651a2009-05-04 18:56:13 +00005702- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5703 sequences. Patch by Nick Barnes and Victor Stinner.
5704
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005705- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005706
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005707- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5708 received a new method, detach(). detach() disconnects the underlying stream
5709 from the buffer or text IO and returns it.
5710
Mark Dickinson33841c32009-05-01 15:37:04 +00005711- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5712 floats with absolute value over 1e50. Also remove length
5713 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5714 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005715
Eric Smith741191f2009-05-06 13:08:15 +00005716- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005717 format(complex(1, 2./3), '.5') now produces a sensible result.
5718
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005719- Issue #5864: Fix empty format code formatting for floats so that it
5720 never gives more than the requested number of significant digits.
5721
Eric Smith6dc46f52009-04-27 20:39:49 +00005722- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5723 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5724
Eric Smithcc32a112009-04-26 21:35:14 +00005725- Issue #5835: Deprecate PyOS_ascii_formatd.
5726
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005727- Issue #4971: Fix titlecase for characters that are their own
5728 titlecase, but not their own uppercase.
5729
Benjamin Peterson193152c2009-04-25 01:08:45 +00005730- Issue #5283: Setting __class__ in __del__ caused a segfault.
5731
Mark Dickinsonad476da2009-04-23 19:14:16 +00005732- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5733 z involves nans, infs or negative zeros.
5734
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005735- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005736
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005737- Issue #1869 (and many duplicates): make round(x, n) correctly
5738 rounded for a float x, by using the decimal <-> binary conversions
5739 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5740 consistently agrees with format(x, '.2f').
5741
Benjamin Petersonae937c02009-04-18 20:54:08 +00005742- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5743 some builtin types.
5744
Eric Smith0923d1d2009-04-16 20:16:10 +00005745- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5746
Eric Smith35e84722009-04-16 20:21:28 +00005747- Issue #5515: str.format() type 'n' combined with commas and leading
5748 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005749
5750- Implement PEP 378, Format Specifier for Thousands Separator, for
5751 floats.
5752
Mark Dickinson3370cce2009-04-17 22:40:53 +00005753- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005754 1e11, not 1e12. This avoids printing 13 significant digits in
5755 situations where only 12 of them are correct. Example problem
5756 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5757 long time.)
5758
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005759- Issue #1580: On most platforms, use a 'short' float repr: for a
5760 finite float x, repr(x) now outputs a string based on the shortest
5761 sequence of decimal digits that rounds to x. Previous behaviour was
5762 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005763 Another minor difference is that the new repr switches to
5764 exponential notation at 1e16 instead of the previous 1e17; this
5765 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005766
5767 There's a new sys attribute sys.float_repr_style, which takes
5768 the value 'short' to indicate that we're using short float repr,
5769 and 'legacy' if the short float repr isn't available for one
5770 reason or another.
5771
5772 The float repr change involves incorporating David Gay's 'perfect
5773 rounding' code into the Python core (it's in Python/dtoa.c). As a
5774 secondary consequence, all string-to-float and float-to-string
5775 conversions (including all float formatting operations) will be
5776 correctly rounded on these platforms.
5777
Georg Brandl5f90d792010-08-01 22:31:05 +00005778 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005779 this change does not apply.
5780
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005781- Issue #5759: float() didn't call __float__ on str subclasses.
5782
Georg Brandlabc38772009-04-12 15:51:51 +00005783- The string.maketrans() function is deprecated; there is a new static method
5784 maketrans() on the bytes and bytearray classes. This removes confusion about
5785 the types string.maketrans() is supposed to work with, and mirrors the
5786 methods available on the str class.
5787
R. David Murraydc6da8a2009-04-09 22:16:43 +00005788- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5789 its clarity and its speed.
5790
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005791- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005792 to avoid compiler warnings.
5793
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005794- Issue #3739: The unicode-internal encoder now reports the number of characters
5795 consumed like any other encoder (instead of the number of bytes).

6112 optional module state data.
6113
Mark Dickinson8055afd2009-01-17 10:04:45 +00006114- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006115 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006116
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006117- Issue #4935: The overflow checking code in the expandtabs() method common
6118 to str, bytes and bytearray could be optimized away by the compiler, letting
6119 the interpreter segfault instead of raising an error.
6120
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006121- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6122 __next__ method.
6123
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006124- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6125 function no longer attempt to call the __long__ slot to convert an object
6126 to an integer. Only the __int__ and __trunc__ slots are examined.

6131
Antoine Pitrouab868312009-01-10 15:40:25 +00006132- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6133 common cases are optimized thanks to a dedicated fast path and a moderate
6134 amount of loop unrolling.
6135
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006136- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6137 collecting the oldest generation) so that allocating lots of objects without
6138 destroying them does not show quadratic performance. Based on a proposal by
6139 Martin von Löwis at
6140 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6141
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006142- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006143 having been closed (for instance, a read() call could return some
6144 previously buffered data). Patch by Dmitry Vasiliev.
6145
Antoine Pitrou05608432009-01-09 18:53:14 +00006146- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6147 flag to work properly. Furthermore, when specifying -u, the text stdout
6148 and stderr streams have line-by-line buffering enabled (the default being
6149 to buffer arbitrary chunks of data).
6150
Raymond Hettinger35631532009-01-09 03:58:09 +00006151- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6152 instead of ints (reducing its size from 4 to 8 times thereby reducing
6153 Python's overall memory).
6154
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006155- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6156 an existing .py counterpart, override the co_filename attributes of all
6157 code objects if the original filename is obsolete (which can happen if the
6158 file has been renamed, moved, or if it is accessed through different paths).
6159 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6160
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006161- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6162 one byte. Also fixes the meaning of len() so that it returns the number of
6163 items, rather than the size in bytes.
6164
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006165- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006167- Issue #4747: When the terminal does not use utf-8, executing a script with

6169
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006170- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

6175
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006176- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6177 where the tp_hash and tp_dict slots are both NULL.
6178
Georg Brandlccc47b62008-12-28 11:44:14 +00006179- Issue #4759: None is now allowed as the first argument of

6181
Skip Montanaro80072cb2008-12-23 03:51:14 +00006182- Added test case to ensure attempts to read from a file opened for writing
6183 fail.

6189
Antoine Pitrou621601a2008-12-17 23:18:19 +00006190- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00006196- Issue #2173: When getting device encoding, check that return value of
6197 nl_langinfo is not the empty string. This was causing silent build
6198 failures on OS X.
6199
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006200- Issue #4597: Fixed several opcodes that weren't always propagating
6201 exceptions.
6202
6203- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006204 context manager returns a value that cannot be converted to a bool.
6205
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006206- Issue #4445: Replace "sizeof(PyBytesObject)" with
6207 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6208 bytes instances. On a typical machine this saves 3 bytes of memory
6209 (on average) per allocation of a bytes instance.
6210
Christian Heimesa872de52008-12-05 08:26:55 +00006211- Issue #4533: File read operation was dreadfully slow due to a slowly
6212 growing read buffer. Fixed by using the same growth rate algorithm as
6213 Python 2.x.
6214
Antoine Pitrou5504e892008-12-06 21:27:53 +00006215- Issue #4509: Various issues surrounding resize of bytearray objects to
6216 which there are buffer exports (e.g. memoryview instances).
6217
Georg Brandlf9734072008-12-07 15:30:06 +00006218- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6219 method on file objects with closefd=False. The file descriptor is still
6220 kept open but the file object behaves like a closed file. The ``FileIO``
6221 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00006223- Issue #4569: Interpreter crash when mutating a memoryview with an item size

6229
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006230- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6231 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6232 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6233 of using the replace error handler in PyUnicode_DecodeUTF8().

6659 from inside a module loaded via a PEP 302 loader and attempting to
6660 perform IO operations based on __file__). Original patch by
6661 Alexander Belopolsky.
6662
6663- Issues #4082 and #4512: Add runpy support to zipimport in a manner that
