572
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +0000573- Issue #10068: Global objects which have reference cycles with their module's
574 dict are now cleared again. This causes issue #7140 to appear again.
575
Victor Stinner257d38f2010-10-09 10:12:11 +0000576- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +0000577 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +0000578
Georg Brandl27a28582010-10-10 09:49:21 +0000579- ast.literal_eval() can now handle negative numbers. It is also a little more
580 liberal in what it accepts without compromising the safety of the evaluation.
581 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +0000582
Benjamin Peterson970d1882010-10-02 17:55:47 +0000583- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
584 result metaclasses can now be ABCs (see #9533).
585
Victor Stinneraef57e32010-10-02 11:50:49 +0000586- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
587
Victor Stinner5593d8a2010-10-02 11:11:27 +0000588- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +0000589 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
590 32 bits wchar_t (eg. Linux in narrow build).

Victor Stinner137c34c2010-09-29 10:25:54 +0000595- Issue #9979: Create function PyUnicode_AsWideCharString().
596
Brett Cannon5305a992010-09-27 21:08:38 +0000597- Issue #7397: Mention that importlib.import_module() is probably what someone
598 really wants to be using in __import__'s docstring.
599
Georg Brandl27a28582010-10-10 09:49:21 +0000600- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
601 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +0000602
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000603- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +0000604 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000605
Brian Curtine8e4b3b2010-09-23 20:04:14 +0000606- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
607
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000608- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
609 threads are still running. Instead, reinitialize the GIL on a second call to
610 Py_Initialize().
611
Georg Brandl27a28582010-10-10 09:49:21 +0000612- All SyntaxErrors now have a column offset and therefore a caret when the error
613 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +0000614
Brett Cannonbc2eff32010-09-19 21:39:02 +0000615- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
616 module that was imported, but instead gets the module from sys.modules.
617
Georg Brandl27a28582010-10-10 09:49:21 +0000618- Issue #9212: The range type_items now provides index() and count() methods, to
619 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +0000620
Georg Brandl27a28582010-10-10 09:49:21 +0000621- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
622 with a non-empty format string. This is an effort to future-proof user
623 code. If a derived class does not currently implement __format__ but later
624 adds its own __format__, it would most likely break user code that had
625 supplied a format string. This will be changed to a DeprecationWaring in
626 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +0000627
Antoine Pitrou1df15362010-09-13 14:16:46 +0000628- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
629 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
630 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
631
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000632- Issue #9210: Configure option --with-wctype-functions was removed. Using the
633 functions from the libc caused the methods .upper() and lower() to become
634 locale aware and created subtly wrong results.
635
Georg Brandl27a28582010-10-10 09:49:21 +0000636- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
637 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000638
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000639- Issue #4617: Previously it was illegal to delete a name from the local
640 namespace if it occurs as a free variable in a nested block. This limitation
641 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
642
Georg Brandl27a28582010-10-10 09:49:21 +0000643- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
644 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
645 Also, the "backslashreplace" error handler now joins surrogate pairs into a
646 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +0000647
Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000648- Issue #9757: memoryview objects get a release() method to release the
649 underlying buffer (previously this was only done when deallocating the
650 memoryview), and gain support for the context management protocol.
651
Antoine Pitrou079ce542010-09-08 12:37:10 +0000652- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
653 thread-local storage key.

666
Antoine Pitroudbec7802010-10-10 09:37:12 +0000667- Issue #9437: Fix building C extensions with non-default LDFLAGS.
668
R. David Murray96fd54e2010-10-08 15:55:28 +0000669- Issue #4661: email can now parse bytes input and generate either converted
670 7bit output or bytes output. Email version bumped to 5.1.0.
671
Antoine Pitrou59fdd672010-10-08 10:37:08 +0000672- Issue #1589: Add ssl.match_hostname(), to help implement server identity

674
Antoine Pitrou7980eaa2010-10-06 21:21:18 +0000675- Issue #9759: GzipFile now raises ValueError when an operation is attempted
676 after the file is closed. Patch by Jeffrey Finkelstein.
677
Éric Araujo6108bf52010-10-04 23:52:37 +0000678- Issue #9042: Fix interaction of custom translation classes and caching in
679 gettext.
680
Éric Araujoef777bd2010-10-05 00:04:20 +0000681- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000682 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000683 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000684 replacement for old handle_accept() and avoids the user to call accept()
685 directly.
686
Lars Gustäbel331b8002010-10-04 15:18:47 +0000687- Issue #9065: tarfile no longer uses "root" as the default for the uname and
688 gname field.

695
Georg Brandl27a28582010-10-10 09:49:21 +0000696- Issue #10004: quoprimime no longer generates a traceback when confronted with
697 invalid characters after '=' in a Q-encoded word.

707
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000708- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +0000709 retry the select() loop instead of bailing out. This is because select() can
710 incorrectly report a socket as ready for reading (for example, if it received
711 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000712

793 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000794 approach of using weakref proxies so that reference cycles never get created
795 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +0000797- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
798 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +0000799 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +0000801- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
802 environment variable to set the filesystem encoding at Python startup.
803 sys.setfilesystemencoding() creates inconsistencies because it is unable to
804 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +0000806- Issue #9410: Various optimizations to the pickle module, leading to speedups
807 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
808 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000809
Georg Brandl27a28582010-10-10 09:49:21 +0000810- The pprint module now supports printing OrderedDicts in their given order
811 (formerly, it would sort the keys).

Georg Brandl27a28582010-10-10 09:49:21 +0000816- Issue #9707: Rewritten reference implementation of threading.local which is
817 friendlier towards reference cycles. This change is not normally visible
818 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000820- Issue #6394: os.getppid() is now supported on Windows. Note that it will
821 still return the id of the parent process after it has exited. This process
822 id may even have been reused by another unrelated process.
823
Georg Brandl27a28582010-10-10 09:49:21 +0000824- Issue #9792: In case of connection failure, socket.create_connection() would
825 swallow the exception and raise a new one, making it impossible to fetch the
826 original errno, or to filter timeout errors. Now the original error is
827 re-raised.

839 the hash value. This makes better use of the seed value and assures the
840 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +0000842 * Improved the random()-->integer algorithm used in choice(), shuffle(),
843 sample(), randrange(), and randint(). Formerly, it used int(n*random())
844 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000845
846 * Improved documentation of arguments to randrange(). Issue #9379.

852 cases now also have assertWarns and assertWarnsRegexp methods to check that a
853 given warning type was triggered by the code under test.

Gregory P. Smith13b55292010-09-06 08:30:23 +0000865- hashlib has two new constant attributes: algorithms_guaranteed and

867 guaranteed to exist in all Python implementations and the names of hash
868 algorithms available in the current process.

997 return characters from the full Unicode range, even on narrow unicode builds
998 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Ezio Melotti57221d02010-07-01 07:32:02 +00001374- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001375 start byte and the continuation byte(s) are now considered invalid, instead of
1376 the number of bytes specified by the start byte. E.g.:
1377 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1378 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1379 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1380 returned a single u'\ufffd'.

1383 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00001394- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
1395 dealing with unary minus applied to a constant. The removed code was mutating
1396 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00001397
Victor Stinner554f3f02010-06-16 23:33:54 +00001398- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00001399 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00001400 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001401 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00001402
Victor Stinner25e8ec42010-06-25 00:02:38 +00001403- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
1404 "w*" format instead. Add tests for "w*" format.
1405
Victor Stinner06e49dd2010-06-13 18:21:50 +00001406- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00001407 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00001408 string formats.
1409
Georg Brandl62069d32010-07-31 08:56:11 +00001410- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001411 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1412 location of the raised exception.
1413
Victor Stinner313a1202010-06-11 23:56:51 +00001414- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1415 filenames and enable os.fsencode().
1416
Benjamin Peterson285a6892010-06-22 19:21:52 +00001417- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
1418
Georg Brandl62069d32010-07-31 08:56:11 +00001419- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
1420 interpreter with characters outside the Basic Multilingual Plane (higher than
1421 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00001422
Georg Brandl62069d32010-07-31 08:56:11 +00001423- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1424 TypeError instead of giving a DeprecationWarning when a float is parsed using
1425 the 'L' code (for long long). (All other integer codes already raise
1426 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001427
Victor Stinner600d3be2010-06-10 12:00:55 +00001428- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1429 enable shortcuts for upper case encoding name. Add also a shortcut for
1430 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1431
Georg Brandl62069d32010-07-31 08:56:11 +00001432- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1433 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001434
1435- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001436 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001437 like bytearray.
1438
Georg Brandl62069d32010-07-31 08:56:11 +00001439- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001440 used anymore and it was never documented.
1441
Georg Brandl62069d32010-07-31 08:56:11 +00001442- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00001443
Georg Brandl62069d32010-07-31 08:56:11 +00001444- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
1445 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001446
Georg Brandl62069d32010-07-31 08:56:11 +00001447- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1448 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1449 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1450 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001451
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001452- Issue #8748: Fix two issues with comparisons between complex and integer
1453 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001454 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1455 (2) The comparison raised an OverflowError for large integers, leading to
1456 unpredictable exceptions when combining integers and complex objects in sets
1457 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001458
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001459- Issue #8766: Initialize _warnings module before importing the first module.
1460 Fix a crash if an empty directory called "encodings" exists in sys.path.
1461
Victor Stinner9ca9c252010-05-19 16:53:30 +00001462- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001463 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001464 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001465
Georg Brandl62069d32010-07-31 08:56:11 +00001466- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1467 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001468
Victor Stinnerae6265f2010-05-15 16:27:27 +00001469- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1470 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001471 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001472 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001473
Victor Stinner59e62db2010-05-15 13:14:32 +00001474- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001475 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001476
Victor Stinnerb744ba12010-05-15 12:27:16 +00001477- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001478 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001479 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1480
Victor Stinner0964ee12010-04-30 16:48:45 +00001481- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001482 PyUnicode_FromString() to support surrogates in the filename and use the right
1483 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00001484
Georg Brandl8569e582010-05-19 20:57:08 +00001485- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
1486
Georg Brandl62069d32010-07-31 08:56:11 +00001487- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00001488
Benjamin Petersonfb886362010-04-24 18:21:17 +00001489- Issue #8419: Prevent the dict constructor from accepting non-string keyword
1490 arguments.
1491
Victor Stinner14284c22010-04-23 12:02:30 +00001492- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00001493 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00001587 where the right hand operand is a set of constants, by turning the set into a
1588 frozenset and pre-building it as a constant. The comparison operation is made
1589 against the constant instead of building a new set each time it is executed (a
1590 similar optimization already existed which turned a list of constants into a
1591 pre-built tuple). Patch and additional tests by Dave Malcolm.

1787 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1788 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001789 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00001799- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
1800 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
1801 accessing the d_type and d_name members of structures using PyDescr_COMMON.

1818 gives improved memory leak detection when running under Valgrind, while taking
1819 advantage of pymalloc at other times.

1895 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001896 applications that use a lot of regular expressions and limits the impact of
1897 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002194- Issue #8524: When creating an SSL socket, the timeout value of the original
2195 socket wasn't retained (instead, a socket with a positive timeout would be
2196 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00002197
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00002198- Issue #5103: SSL handshake would ignore the socket timeout and block
2199 indefinitely if the other end didn't respond.
2200
Georg Brandl62069d32010-07-31 08:56:11 +00002201- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2202 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00002213- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
2214 string "python" as the *ident*. openlog() arguments are all optional and
2215 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00002216
Georg Brandl62069d32010-07-31 08:56:11 +00002217- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
2218 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00002219 wanting to continue using the socket in clear-text mode, by disabling
2220 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

2254 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
2255
Victor Stinner0e59cc32010-04-16 23:49:32 +00002256- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

2268
Georg Brandl62069d32010-07-31 08:56:11 +00002269- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002270 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00002271 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002272
Victor Stinner485fb562010-04-13 11:07:24 +00002273- Issue #8383: pickle and pickletools use surrogatepass error handler when

R. David Murrayb2416e52010-04-12 16:58:02 +00002277- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00002278 filename and date, conforming to the 'standards' they were originally designed
2279 to follow. This improves compatibility with patch tools.

Antoine Pitrou04f6a322010-04-05 21:40:07 +00002291- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00002292 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2293 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00002294
Raymond Hettingerc50846a2010-04-05 18:56:31 +00002295- Add functools.total_ordering() and functools.cmp_to_key().
2296
Georg Brandl62069d32010-07-31 08:56:11 +00002297- Issue #8257: The Decimal construct now accepts a float instance directly,
2298 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00002299
2300 >>> Decimal(1.1)
2301 Decimal('1.100000000000000088817841970012523233890533447265625')
2302
Georg Brandl62069d32010-07-31 08:56:11 +00002303- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2304 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00002305
Georg Brandl62069d32010-07-31 08:56:11 +00002306- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2307 InvalidOperation instead of returning False. (Comparisons involving a quiet
2308 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2309 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002310
Georg Brandl62069d32010-07-31 08:56:11 +00002311- Issue #2531: Comparison operations between floats and Decimal instances now
2312 return a result based on the numeric values of the operands; previously they
2313 returned an arbitrary result based on the relative ordering of id(float) and
2314 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2315 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002316
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002317- Added a subtract() method to collections.Counter().
2318
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002319- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002320 argument `-` which tells it to read files to compile from stdin. Each line is
2321 read on demand and the named file is compiled immediately. (Original patch by
2322 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002323
Florent Xicluna806d8cf2010-03-30 19:34:18 +00002324- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2325 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00002326 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00002328- Comparisons using one of <, <=, >, >= between a complex instance and a
2329 Fractions instance now raise TypeError instead of returning True/False. This
2330 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2331 <=> complex, and complex <=> complex comparisons.

2338 running from the build directory (POSIX only).
2339
Antoine Pitrou910bd512010-03-22 20:11:09 +00002340- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002341 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2342 silenced.

Georg Brandl62069d32010-07-31 08:56:11 +00002374- The internals of the subprocess module on POSIX systems have been replaced by
2375 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2376 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00002377
Georg Brandl62069d32010-07-31 08:56:11 +00002378- subprocess.Popen now has restore_signals and start_new_session features. The
2379 default of restore_signals=True is a new behavior compared to earlier Python
2380 versions. This means that signals such as SIGPIPE are not ignored by default
2381 in subprocesses launched by Python (Issue #1652).

Antoine Pitrou434736a2009-11-10 18:46:01 +00002657- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00002658 default when instantiating a `threading.RLock` object. This makes recursive
2659 locks as fast as regular non-recursive locks (previously, they were slower by
2660 10x to 15x).

2680 from stdin so that existing input does not confuse it and lead to incorrect
2681 entry or an IOError. It also properly flushes it afterwards to avoid the
2682 terminal echoing the input afterwards on OSes such as Solaris.

Georg Brandl62069d32010-07-31 08:56:11 +00002875 compared to other unix systems. In particular, os.getgroups() does not reflect

2904 Prior to this change, timezone adjustment in utctimetuple() could produce
2905 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00002908- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
2909 directive. When the ``%z`` directive is present in the format string, an
2910 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2911 ``datetime.timezone`` instance constructed from the parsed offset. If both
2912 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2913 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002915- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002916 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2917 ``datetime.timezone``, return fixed name and UTC offset from their
2918 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2919 returns ``None``. A class attribute, ``utc`` contains an instance
2920 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00003245 runtest_inner in regrtest, with warnings if the called test modifies them, and

3391Core and Builtins
3392-----------------
3393
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00003394- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
3395 of the command line.
3396
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00003397- Issue #6012: Add cleanup support to O& argument parsing.
3398
Eric Smith41669ca2009-05-23 14:23:22 +00003399- Issue #6089: Fixed str.format with certain invalid field specifiers
3400 that would raise SystemError.
3401
Raymond Hettinger2bcde142009-05-29 04:52:27 +00003402- Issue #5982: staticmethod and classmethod now expose the wrapped
3403 function with __func__.
3404
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00003405- Added support for multiple context managers in the same with-statement.
3406 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00003407
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00003408- Issue #5829: complex("1e500") no longer raises OverflowError. This
3409 makes it consistent with float("1e500") and interpretation of real
3410 and imaginary literals.
3411
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00003412- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
3413
R. David Murraydd226ea2009-05-13 12:27:21 +00003414- Issue #5994: the marshal module now has docstrings.
3415
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00003416- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
3417 (1) inf and nan strings with trailing whitespace were incorrectly
3418 rejected; (2) parsing of strings representing infinities and nans
3419 was locale aware; and (3) the interpretation of fromhex('-nan')
3420 didn't match that of float('-nan').

3423-------
3424
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00003425- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
3426
R. David Murrayfb123912009-05-28 18:19:00 +00003427- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
3428
R. David Murray1f1b9d32009-05-27 20:56:59 +00003429- Issue #6121: pydoc now ignores leading and trailing spaces in the
3430 argument to the 'help' function.
3431
Georg Brandlfaf41492009-05-26 18:31:11 +00003432- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
3433 arguments for strings with a space in them.
3434
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00003435- collections.namedtuple() was not working with the following field
3436 names: cls, self, tuple, itemgetter, and property.
3437
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00003438- In unittest, using a skipping decorator on a class is now equivalent to
3439 skipping every test on the class. The ClassTestSuite class has been removed.
3440
Martin v. Löwis70ccd162009-05-24 19:47:22 +00003441- Issue #6050: Don't fail extracting a directory from a zipfile if
3442 the directory already exists.
3443
Antoine Pitrou61f77b52009-05-24 15:46:13 +00003444- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
3445 than an int, which makes some operations possible under 64-bit Linux (e.g.
3446 DN_MULTISHOT with F_NOTIFY).
3447
Antoine Pitrou716c4442009-05-23 19:04:03 +00003448- Issue #5761: Add the name of the underlying file to the repr() of various
3449 IO objects.
3450
R. David Murraycaa27b72009-05-23 18:49:56 +00003451- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
3452 by Musashi Tamura, tests by Marcin Bachry.
3453
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00003454- Issue #1983: Fix functions taking or returning a process identifier to use
3455 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
3456 a process identifier type wider than the standard C integer type.
3457
R. David Murray87e20742009-05-23 01:30:26 +00003458- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
3459 Patch by Farhan Ahmad, test by Marcin Bachry.
3460
Antoine Pitrou6e610062009-05-15 17:04:50 +00003461- Issue #2116: Weak references and weak dictionaries now support copy()ing and
3462 deepcopy()ing.
3463
Antoine Pitrouc1d09362009-05-15 12:15:51 +00003464- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

Antoine Pitrou37d1c182009-05-14 21:54:00 +00003466- Issue #5918: Fix a crash in the parser module.
3467
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00003468- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
3469
Antoine Pitroue4501852009-05-14 18:55:55 +00003470- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
3471 library. This means, for example, that opening an UTF-16 text file in
3472 append mode doesn't add a BOM at the end of the file if the file isn't
3473 empty.
3474
R. David Murray74b89242009-05-13 17:33:03 +00003475- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
3476 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
3477 corrects a pydoc regression.
3478
Georg Brandl5f90d792010-08-01 22:31:05 +00003479- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00003480 now it does. This also means getfp method now returns the real fp.

3483------------
3484
3485- Issue #6047: fullinstall has been removed because Python 3's executable will
3486 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00003487
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00003488- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00003512- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00003513 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00003518What's New in Python 3.1 beta 1?
3519================================
3520
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00003521*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00003522
3523Core and Builtins
3524-----------------
3525
Mark Dickinson865e01a2009-05-07 16:37:01 +00003526- Issue #5914: Add new C API function PyOS_string_to_double, and
3527 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3528
Eric Smith741191f2009-05-06 13:08:15 +00003529- Issue #3382: float.__format__, complex.__format__, and %-formatting
3530 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
3531 affects nan -> NAN and inf -> INF.
3532
Mark Hammond5a607a32009-05-06 08:04:54 +00003533- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
3534 in all operations, including splitdrive, split, etc. splitunc() now issues
3535 a PendingDeprecation warning.
3536
Eric Smith63376222009-05-05 14:04:18 +00003537- Issue #5920: For float.__format__, change the behavior with the
3538 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3539 to be like 'g' but with at least one decimal point and with a
3540 default precision of 12. Previously, the behavior the same but with
3541 a default precision of 6. This more closely matches str(), and
3542 reduces surprises when adding alignment flags to the empty
3543 presentation type. This also affects the new complex.__format__ in
3544 the same way.
3545
Martin v. Löwis011e8422009-05-05 04:43:17 +00003546- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
3547
R. David Murrayb18500d2009-05-04 22:59:07 +00003548- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3549 shadowed by classtype's, even if it was None. property now
3550 inserts the __doc__ into the subclass instance __dict__.
3551
Antoine Pitrou244651a2009-05-04 18:56:13 +00003552- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3553 sequences. Patch by Nick Barnes and Victor Stinner.
3554
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003555- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003556
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003557- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3558 received a new method, detach(). detach() disconnects the underlying stream
3559 from the buffer or text IO and returns it.
3560
Mark Dickinson33841c32009-05-01 15:37:04 +00003561- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3562 floats with absolute value over 1e50. Also remove length
3563 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3564 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003565
Eric Smith741191f2009-05-06 13:08:15 +00003566- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003567 format(complex(1, 2./3), '.5') now produces a sensible result.
3568
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003569- Issue #5864: Fix empty format code formatting for floats so that it
3570 never gives more than the requested number of significant digits.
3571
Eric Smith6dc46f52009-04-27 20:39:49 +00003572- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3573 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3574
Eric Smithcc32a112009-04-26 21:35:14 +00003575- Issue #5835: Deprecate PyOS_ascii_formatd.
3576
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003577- Issue #4971: Fix titlecase for characters that are their own
3578 titlecase, but not their own uppercase.
3579
Benjamin Peterson193152c2009-04-25 01:08:45 +00003580- Issue #5283: Setting __class__ in __del__ caused a segfault.
3581
Mark Dickinsonad476da2009-04-23 19:14:16 +00003582- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3583 z involves nans, infs or negative zeros.
3584
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003585- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003586
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003587- Issue #1869 (and many duplicates): make round(x, n) correctly
3588 rounded for a float x, by using the decimal <-> binary conversions
3589 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3590 consistently agrees with format(x, '.2f').
3591
Benjamin Petersonae937c02009-04-18 20:54:08 +00003592- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3593 some builtin types.
3594
Eric Smith0923d1d2009-04-16 20:16:10 +00003595- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3596
Eric Smith35e84722009-04-16 20:21:28 +00003597- Issue #5515: str.format() type 'n' combined with commas and leading
3598 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003599
3600- Implement PEP 378, Format Specifier for Thousands Separator, for
3601 floats.
3602
Mark Dickinson3370cce2009-04-17 22:40:53 +00003603- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003604 1e11, not 1e12. This avoids printing 13 significant digits in
3605 situations where only 12 of them are correct. Example problem
3606 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3607 long time.)
3608
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003609- Issue #1580: On most platforms, use a 'short' float repr: for a
3610 finite float x, repr(x) now outputs a string based on the shortest
3611 sequence of decimal digits that rounds to x. Previous behaviour was
3612 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003613 Another minor difference is that the new repr switches to
3614 exponential notation at 1e16 instead of the previous 1e17; this
3615 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003616
3617 There's a new sys attribute sys.float_repr_style, which takes
3618 the value 'short' to indicate that we're using short float repr,
3619 and 'legacy' if the short float repr isn't available for one
3620 reason or another.
3621
3622 The float repr change involves incorporating David Gay's 'perfect
3623 rounding' code into the Python core (it's in Python/dtoa.c). As a
3624 secondary consequence, all string-to-float and float-to-string
3625 conversions (including all float formatting operations) will be
3626 correctly rounded on these platforms.
3627
Georg Brandl5f90d792010-08-01 22:31:05 +00003628 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003629 this change does not apply.
3630
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003631- Issue #5759: float() didn't call __float__ on str subclasses.
3632
Georg Brandlabc38772009-04-12 15:51:51 +00003633- The string.maketrans() function is deprecated; there is a new static method
3634 maketrans() on the bytes and bytearray classes. This removes confusion about
3635 the types string.maketrans() is supposed to work with, and mirrors the
3636 methods available on the str class.
3637
R. David Murraydc6da8a2009-04-09 22:16:43 +00003638- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3639 its clarity and its speed.
3640
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003641- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003642 to avoid compiler warnings.
3643
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003644- Issue #3739: The unicode-internal encoder now reports the number of characters
3645 consumed like any other encoder (instead of the number of bytes).

3659
Raymond Hettingereb816952009-05-29 01:22:18 +00003660- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003967- Issue #4935: The overflow checking code in the expandtabs() method common
3968 to str, bytes and bytearray could be optimized away by the compiler, letting
3969 the interpreter segfault instead of raising an error.
3970
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003971- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3972 __next__ method.
3973
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003974- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3975 function no longer attempt to call the __long__ slot to convert an object
3976 to an integer. Only the __int__ and __trunc__ slots are examined.

3981
Antoine Pitrouab868312009-01-10 15:40:25 +00003982- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3983 common cases are optimized thanks to a dedicated fast path and a moderate
3984 amount of loop unrolling.
3985
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003986- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3987 collecting the oldest generation) so that allocating lots of objects without
3988 destroying them does not show quadratic performance. Based on a proposal by
3989 Martin von Löwis at
3990 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3991
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003992- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003993 having been closed (for instance, a read() call could return some
3994 previously buffered data). Patch by Dmitry Vasiliev.
3995
Antoine Pitrou05608432009-01-09 18:53:14 +00003996- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3997 flag to work properly. Furthermore, when specifying -u, the text stdout
3998 and stderr streams have line-by-line buffering enabled (the default being
3999 to buffer arbitrary chunks of data).
4000
Raymond Hettinger35631532009-01-09 03:58:09 +00004001- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4002 instead of ints (reducing its size from 4 to 8 times thereby reducing
4003 Python's overall memory).
4004
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004005- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4006 an existing .py counterpart, override the co_filename attributes of all
4007 code objects if the original filename is obsolete (which can happen if the
4008 file has been renamed, moved, or if it is accessed through different paths).
4009 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4010
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004011- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4012 one byte. Also fixes the meaning of len() so that it returns the number of
4013 items, rather than the size in bytes.
4014
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004015- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004017- Issue #4747: When the terminal does not use utf-8, executing a script with
4018 non-ascii characters in its name could fail with a "SyntaxError: None" error.
4019
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004020- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

4024 did not get collected.
4025
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004026- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4027 where the tp_hash and tp_dict slots are both NULL.
4028
Georg Brandlccc47b62008-12-28 11:44:14 +00004029- Issue #4759: None is now allowed as the first argument of

4031
Skip Montanaro80072cb2008-12-23 03:51:14 +00004032- Added test case to ensure attempts to read from a file opened for writing
4033 fail.
4034

4039
Antoine Pitrou621601a2008-12-17 23:18:19 +00004040- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

4042 unreachable. Original patch by Neil Schemenauer.
4043

4045
Mark Dickinsonda2706b2008-12-11 18:03:03 +00004046- Issue #2173: When getting device encoding, check that return value of
4047 nl_langinfo is not the empty string. This was causing silent build
4048 failures on OS X.
4049
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00004050- Issue #4597: Fixed several opcodes that weren't always propagating
4051 exceptions.
4052
4053- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00004054 context manager returns a value that cannot be converted to a bool.
4055
Mark Dickinsonfd24b322008-12-06 15:33:31 +00004056- Issue #4445: Replace "sizeof(PyBytesObject)" with
4057 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
4058 bytes instances. On a typical machine this saves 3 bytes of memory
4059 (on average) per allocation of a bytes instance.
4060
Christian Heimesa872de52008-12-05 08:26:55 +00004061- Issue #4533: File read operation was dreadfully slow due to a slowly
4062 growing read buffer. Fixed by using the same growth rate algorithm as
4063 Python 2.x.
4064
Antoine Pitrou5504e892008-12-06 21:27:53 +00004065- Issue #4509: Various issues surrounding resize of bytearray objects to
4066 which there are buffer exports (e.g. memoryview instances).
4067
Georg Brandlf9734072008-12-07 15:30:06 +00004068- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
4069 method on file objects with closefd=False. The file descriptor is still
4070 kept open but the file object behaves like a closed file. The ``FileIO``
4071 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00004072
Antoine Pitroubc420402008-12-07 20:14:49 +00004073- Issue #4569: Interpreter crash when mutating a memoryview with an item size
4074 larger than 1.

4079
Walter Dörwaldc1651a02009-05-03 22:55:55 +00004080- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
4081 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4082 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4083 of using the replace error handler in PyUnicode_DecodeUTF8().

4404 do an explicit seek to the end of file (so that e.g. tell() returns the
