573Core and Builtins
574-----------------
575
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +0000576- Issue #10068: Global objects which have reference cycles with their module's
577 dict are now cleared again. This causes issue #7140 to appear again.
578
Victor Stinner257d38f2010-10-09 10:12:11 +0000579- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +0000580 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +0000581
Georg Brandl27a28582010-10-10 09:49:21 +0000582- ast.literal_eval() can now handle negative numbers. It is also a little more
583 liberal in what it accepts without compromising the safety of the evaluation.
584 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +0000585
Benjamin Peterson970d1882010-10-02 17:55:47 +0000586- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
587 result metaclasses can now be ABCs (see #9533).
588
Victor Stinneraef57e32010-10-02 11:50:49 +0000589- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
590
Victor Stinner5593d8a2010-10-02 11:11:27 +0000591- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +0000592 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
593 32 bits wchar_t (eg. Linux in narrow build).

599
Brett Cannon5305a992010-09-27 21:08:38 +0000600- Issue #7397: Mention that importlib.import_module() is probably what someone
601 really wants to be using in __import__'s docstring.
602
Georg Brandl27a28582010-10-10 09:49:21 +0000603- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
604 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +0000605
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000606- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +0000607 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +0000608
Brian Curtine8e4b3b2010-09-23 20:04:14 +0000609- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
610
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +0000611- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
612 threads are still running. Instead, reinitialize the GIL on a second call to
613 Py_Initialize().
614
Georg Brandl27a28582010-10-10 09:49:21 +0000615- All SyntaxErrors now have a column offset and therefore a caret when the error
616 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +0000617
Brett Cannonbc2eff32010-09-19 21:39:02 +0000618- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
619 module that was imported, but instead gets the module from sys.modules.
620
Georg Brandl27a28582010-10-10 09:49:21 +0000621- Issue #9212: The range type_items now provides index() and count() methods, to
622 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +0000623
Georg Brandl27a28582010-10-10 09:49:21 +0000624- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
625 with a non-empty format string. This is an effort to future-proof user
626 code. If a derived class does not currently implement __format__ but later
627 adds its own __format__, it would most likely break user code that had
628 supplied a format string. This will be changed to a DeprecationWaring in
629 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +0000630
Antoine Pitrou1df15362010-09-13 14:16:46 +0000631- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
632 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
633 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
634
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000635- Issue #9210: Configure option --with-wctype-functions was removed. Using the
636 functions from the libc caused the methods .upper() and lower() to become
637 locale aware and created subtly wrong results.
638
Georg Brandl27a28582010-10-10 09:49:21 +0000639- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
640 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +0000641
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000642- Issue #4617: Previously it was illegal to delete a name from the local
643 namespace if it occurs as a free variable in a nested block. This limitation
644 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
645
Georg Brandl27a28582010-10-10 09:49:21 +0000646- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
647 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
648 Also, the "backslashreplace" error handler now joins surrogate pairs into a
649 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +0000650
Antoine Pitrou6e6cc832010-09-09 12:59:39 +0000651- Issue #9757: memoryview objects get a release() method to release the
652 underlying buffer (previously this was only done when deallocating the
653 memoryview), and gain support for the context management protocol.
654
Antoine Pitrou079ce542010-09-08 12:37:10 +0000655- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
656 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +0000672- Issue #4661: email can now parse bytes input and generate either converted
673 7bit output or bytes output. Email version bumped to 5.1.0.
674
Antoine Pitrou59fdd672010-10-08 10:37:08 +0000675- Issue #1589: Add ssl.match_hostname(), to help implement server identity

677
Antoine Pitrou7980eaa2010-10-06 21:21:18 +0000678- Issue #9759: GzipFile now raises ValueError when an operation is attempted
679 after the file is closed. Patch by Jeffrey Finkelstein.
680
Éric Araujo6108bf52010-10-04 23:52:37 +0000681- Issue #9042: Fix interaction of custom translation classes and caching in
682 gettext.
683
Éric Araujoef777bd2010-10-05 00:04:20 +0000684- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000685 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000686 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000687 replacement for old handle_accept() and avoids the user to call accept()
688 directly.
689
Lars Gustäbel331b8002010-10-04 15:18:47 +0000690- Issue #9065: tarfile no longer uses "root" as the default for the uname and

710
Antoine Pitrou3e1fd272010-09-28 21:23:11 +0000711- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +0000712 retry the select() loop instead of bailing out. This is because select() can
713 incorrectly report a socket as ready for reading (for example, if it received
714 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +0000794- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000795 it possible for the user to create self-referencing ordered dictionaries which
796 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000797 approach of using weakref proxies so that reference cycles never get created
798 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +0000800- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
801 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +0000802 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +0000803
Georg Brandl27a28582010-10-10 09:49:21 +0000804- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
805 environment variable to set the filesystem encoding at Python startup.
806 sys.setfilesystemencoding() creates inconsistencies because it is unable to
807 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +0000808
Georg Brandl27a28582010-10-10 09:49:21 +0000809- Issue #9410: Various optimizations to the pickle module, leading to speedups
810 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
811 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +0000812
Georg Brandl27a28582010-10-10 09:49:21 +0000813- The pprint module now supports printing OrderedDicts in their given order
814 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +0000816- Logging: Added QueueHandler class to facilitate logging usage with
817 multiprocessing.
818
Georg Brandl27a28582010-10-10 09:49:21 +0000819- Issue #9707: Rewritten reference implementation of threading.local which is
820 friendlier towards reference cycles. This change is not normally visible
821 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +0000822
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000823- Issue #6394: os.getppid() is now supported on Windows. Note that it will
824 still return the id of the parent process after it has exited. This process
825 id may even have been reused by another unrelated process.
826
Georg Brandl27a28582010-10-10 09:49:21 +0000827- Issue #9792: In case of connection failure, socket.create_connection() would
828 swallow the exception and raise a new one, making it impossible to fetch the
829 original errno, or to filter timeout errors. Now the original error is
830 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +0000832- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
833 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
834 back after the system call. Original patch by Brian Brazil.

Georg Brandl27a28582010-10-10 09:49:21 +0000841 * Update the seed() method to use all of the bits in a string instead of just
842 the hash value. This makes better use of the seed value and assures the
843 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000844
Georg Brandl27a28582010-10-10 09:49:21 +0000845 * Improved the random()-->integer algorithm used in choice(), shuffle(),
846 sample(), randrange(), and randint(). Formerly, it used int(n*random())
847 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000848
849 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +0000854- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
855 cases now also have assertWarns and assertWarnsRegexp methods to check that a
856 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +0000857
Georg Brandl27a28582010-10-10 09:49:21 +0000858- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of

Antoine Pitrou0d739d72010-09-05 23:01:12 +0000864- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +0000865 unsupported operation is attempted (for example, writing to a file open only
866 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +0000868- hashlib has two new constant attributes: algorithms_guaranteed and
869 algorithms_avaiable that respectively list the names of hash algorithms
870 guaranteed to exist in all Python implementations and the names of hash
871 algorithms available in the current process.
872

1000 return characters from the full Unicode range, even on narrow unicode builds
1001 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
1002 in Python is that unicodedata.numeric() now returns the correct value for
1003 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00001040- Issue #9416: Fix some issues with complex formatting where the output with no
1041 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00001042
1043 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00001377- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00001378 start byte and the continuation byte(s) are now considered invalid, instead of
1379 the number of bytes specified by the start byte. E.g.:
1380 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
1381 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1382 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1383 returned a single u'\ufffd'.

1398 dealing with unary minus applied to a constant. The removed code was mutating
1399 the ST, causing a second compilation to fail.

Georg Brandl62069d32010-07-31 08:56:11 +00001402 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00001403 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00001404 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00001405
Victor Stinner25e8ec42010-06-25 00:02:38 +00001406- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
1407 "w*" format instead. Add tests for "w*" format.
1408
Victor Stinner06e49dd2010-06-13 18:21:50 +00001409- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00001410 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00001411 string formats.
1412
Georg Brandl62069d32010-07-31 08:56:11 +00001413- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00001414 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
1415 location of the raised exception.
1416
Victor Stinner313a1202010-06-11 23:56:51 +00001417- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
1418 filenames and enable os.fsencode().
1419
Benjamin Peterson285a6892010-06-22 19:21:52 +00001420- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
1421
Georg Brandl62069d32010-07-31 08:56:11 +00001422- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
1423 interpreter with characters outside the Basic Multilingual Plane (higher than
1424 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00001425
Georg Brandl62069d32010-07-31 08:56:11 +00001426- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
1427 TypeError instead of giving a DeprecationWarning when a float is parsed using
1428 the 'L' code (for long long). (All other integer codes already raise
1429 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00001430
Victor Stinner600d3be2010-06-10 12:00:55 +00001431- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
1432 enable shortcuts for upper case encoding name. Add also a shortcut for
1433 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
1434
Georg Brandl62069d32010-07-31 08:56:11 +00001435- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
1436 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001437
1438- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00001439 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00001440 like bytearray.
1441
Georg Brandl62069d32010-07-31 08:56:11 +00001442- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00001443 used anymore and it was never documented.
1444
Georg Brandl62069d32010-07-31 08:56:11 +00001445- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00001446
Georg Brandl62069d32010-07-31 08:56:11 +00001447- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
1448 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00001449
Georg Brandl62069d32010-07-31 08:56:11 +00001450- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
1451 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
1452 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
1453 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00001454
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001455- Issue #8748: Fix two issues with comparisons between complex and integer
1456 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001457 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1458 (2) The comparison raised an OverflowError for large integers, leading to
1459 unpredictable exceptions when combining integers and complex objects in sets
1460 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00001461
Victor Stinner7d79b8b2010-05-19 20:40:50 +00001462- Issue #8766: Initialize _warnings module before importing the first module.
1463 Fix a crash if an empty directory called "encodings" exists in sys.path.
1464
Victor Stinner9ca9c252010-05-19 16:53:30 +00001465- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00001466 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00001467 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00001468
Georg Brandl62069d32010-07-31 08:56:11 +00001469- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
1470 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00001471
Victor Stinnerae6265f2010-05-15 16:27:27 +00001472- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
1473 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00001474 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00001475 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00001476
Victor Stinner59e62db2010-05-15 13:14:32 +00001477- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00001478 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00001479
Victor Stinnerb744ba12010-05-15 12:27:16 +00001480- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00001481 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00001482 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
1483
Victor Stinner0964ee12010-04-30 16:48:45 +00001484- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00001485 PyUnicode_FromString() to support surrogates in the filename and use the right
1486 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00001488- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
1489
Georg Brandl62069d32010-07-31 08:56:11 +00001490- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00001491
Benjamin Petersonfb886362010-04-24 18:21:17 +00001492- Issue #8419: Prevent the dict constructor from accepting non-string keyword
1493 arguments.
1494
Victor Stinner14284c22010-04-23 12:02:30 +00001495- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00001496 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00001589- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00001590 where the right hand operand is a set of constants, by turning the set into a
1591 frozenset and pre-building it as a constant. The comparison operation is made
1592 against the constant instead of building a new set each time it is executed (a
1593 similar optimization already existed which turned a list of constants into a
1594 pre-built tuple). Patch and additional tests by Dave Malcolm.

1620 of integers: the result of a/b is now correctly rounded for ints a and b (at
1621 least on IEEE 754 platforms), and in particular does not depend on the
1622 internal representation of an int.

1650 long but the length of the range did not. Also fix several cases where

1765
Mark Dickinsone6fc7402010-08-06 18:55:26 +00001766- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
1767 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

1790 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
1791 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00001792 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00001802- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
1803 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
1804 accessing the d_type and d_name members of structures using PyDescr_COMMON.

1821 gives improved memory leak detection when running under Valgrind, while taking
1822 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00001897 simply clearing the entire cache on overflow to forgetting the least recently
1898 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001899 applications that use a lot of regular expressions and limits the impact of
1900 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002192- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2193 the method could block indefinitely if called just before the event loop
2194 started running. This also fixes the occasional freezes witnessed in
2195 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00002197- Issue #8524: When creating an SSL socket, the timeout value of the original
2198 socket wasn't retained (instead, a socket with a positive timeout would be
2199 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00002200
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00002201- Issue #5103: SSL handshake would ignore the socket timeout and block
2202 indefinitely if the other end didn't respond.
2203
Georg Brandl62069d32010-07-31 08:56:11 +00002204- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2205 SSL structure if necessary (as other methods already do).
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00002206
Georg Brandl62069d32010-07-31 08:56:11 +00002207- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and

Georg Brandl62069d32010-07-31 08:56:11 +00002216- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
2217 string "python" as the *ident*. openlog() arguments are all optional and
2218 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00002219
Georg Brandl62069d32010-07-31 08:56:11 +00002220- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
2221 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00002222 wanting to continue using the socket in clear-text mode, by disabling
2223 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
2224
Antoine Pitrou7062db82010-04-22 13:30:10 +00002225- Issue #8496: make mailcap.lookup() always return a list, rather than an

2257 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
2258
Victor Stinner0e59cc32010-04-16 23:49:32 +00002259- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
2260 the current working directory.
2261
Victor Stinner5bfe1462010-04-16 13:28:05 +00002262- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII

Senthil Kumaranad02d232010-04-16 03:02:13 +00002267- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
2268 Locke and Hans Ulrich Niedermann.
2269

2271
Georg Brandl62069d32010-07-31 08:56:11 +00002272- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002273 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00002274 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00002275
Victor Stinner485fb562010-04-13 11:07:24 +00002276- Issue #8383: pickle and pickletools use surrogatepass error handler when
2277 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00002278 Python 2.x and 3.x.

R. David Murrayb2416e52010-04-12 16:58:02 +00002280- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00002281 filename and date, conforming to the 'standards' they were originally designed
2282 to follow. This improves compatibility with patch tools.

Antoine Pitrou04f6a322010-04-05 21:40:07 +00002294- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00002295 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2296 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00002297
Raymond Hettingerc50846a2010-04-05 18:56:31 +00002298- Add functools.total_ordering() and functools.cmp_to_key().
2299
Georg Brandl62069d32010-07-31 08:56:11 +00002300- Issue #8257: The Decimal construct now accepts a float instance directly,
2301 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00002302
2303 >>> Decimal(1.1)
2304 Decimal('1.100000000000000088817841970012523233890533447265625')
2305
Georg Brandl62069d32010-07-31 08:56:11 +00002306- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2307 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00002308
Georg Brandl62069d32010-07-31 08:56:11 +00002309- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2310 InvalidOperation instead of returning False. (Comparisons involving a quiet
2311 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2312 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002313
Georg Brandl62069d32010-07-31 08:56:11 +00002314- Issue #2531: Comparison operations between floats and Decimal instances now
2315 return a result based on the numeric values of the operands; previously they
2316 returned an arbitrary result based on the relative ordering of id(float) and
2317 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2318 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00002319
Raymond Hettinger9c01e442010-04-03 10:32:58 +00002320- Added a subtract() method to collections.Counter().
2321
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002322- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002323 argument `-` which tells it to read files to compile from stdin. Each line is
2324 read on demand and the named file is compiled immediately. (Original patch by
2325 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00002326
Florent Xicluna806d8cf2010-03-30 19:34:18 +00002327- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2328 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00002329 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00002331- Comparisons using one of <, <=, >, >= between a complex instance and a
2332 Fractions instance now raise TypeError instead of returning True/False. This
2333 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2334 <=> complex, and complex <=> complex comparisons.

2341 running from the build directory (POSIX only).
2342
Antoine Pitrou910bd512010-03-22 20:11:09 +00002343- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00002344 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2345 silenced.

Georg Brandl62069d32010-07-31 08:56:11 +00002377- The internals of the subprocess module on POSIX systems have been replaced by
2378 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2379 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00002380
Georg Brandl62069d32010-07-31 08:56:11 +00002381- subprocess.Popen now has restore_signals and start_new_session features. The
2382 default of restore_signals=True is a new behavior compared to earlier Python
2383 versions. This means that signals such as SIGPIPE are not ignored by default
2384 in subprocesses launched by Python (Issue #1652).

2479 issue where interleaved calls to `read()` and `readline()` give wrong results.

Antoine Pitrou434736a2009-11-10 18:46:01 +00002660- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00002661 default when instantiating a `threading.RLock` object. This makes recursive
2662 locks as fast as regular non-recursive locks (previously, they were slower by
2663 10x to 15x).

2912 directive. When the ``%z`` directive is present in the format string, an
2913 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2914 ``datetime.timezone`` instance constructed from the parsed offset. If both
2915 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2916 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00002918- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00002919 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2920 ``datetime.timezone``, return fixed name and UTC offset from their
2921 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2922 returns ``None``. A class attribute, ``utc`` contains an instance
2923 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00003248 runtest_inner in regrtest, with warnings if the called test modifies them, and

3394Core and Builtins
3395-----------------
3396
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00003397- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
3398 of the command line.
3399
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00003400- Issue #6012: Add cleanup support to O& argument parsing.
3401
Eric Smith41669ca2009-05-23 14:23:22 +00003402- Issue #6089: Fixed str.format with certain invalid field specifiers
3403 that would raise SystemError.
3404
Raymond Hettinger2bcde142009-05-29 04:52:27 +00003405- Issue #5982: staticmethod and classmethod now expose the wrapped
3406 function with __func__.
3407
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00003408- Added support for multiple context managers in the same with-statement.
3409 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00003410
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00003411- Issue #5829: complex("1e500") no longer raises OverflowError. This
3412 makes it consistent with float("1e500") and interpretation of real
3413 and imaginary literals.
3414
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00003415- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
3416
R. David Murraydd226ea2009-05-13 12:27:21 +00003417- Issue #5994: the marshal module now has docstrings.
3418
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00003419- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
3420 (1) inf and nan strings with trailing whitespace were incorrectly
3421 rejected; (2) parsing of strings representing infinities and nans
3422 was locale aware; and (3) the interpretation of fromhex('-nan')
3423 didn't match that of float('-nan').

3426-------
3427
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00003428- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
3429
R. David Murrayfb123912009-05-28 18:19:00 +00003430- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
3431
R. David Murray1f1b9d32009-05-27 20:56:59 +00003432- Issue #6121: pydoc now ignores leading and trailing spaces in the
3433 argument to the 'help' function.
3434
Georg Brandlfaf41492009-05-26 18:31:11 +00003435- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
3436 arguments for strings with a space in them.
3437
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00003438- collections.namedtuple() was not working with the following field
3439 names: cls, self, tuple, itemgetter, and property.
3440
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00003441- In unittest, using a skipping decorator on a class is now equivalent to
3442 skipping every test on the class. The ClassTestSuite class has been removed.
3443
Martin v. Löwis70ccd162009-05-24 19:47:22 +00003444- Issue #6050: Don't fail extracting a directory from a zipfile if
3445 the directory already exists.
3446
Antoine Pitrou61f77b52009-05-24 15:46:13 +00003447- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
3448 than an int, which makes some operations possible under 64-bit Linux (e.g.
3449 DN_MULTISHOT with F_NOTIFY).
3450
Antoine Pitrou716c4442009-05-23 19:04:03 +00003451- Issue #5761: Add the name of the underlying file to the repr() of various
3452 IO objects.
3453
R. David Murraycaa27b72009-05-23 18:49:56 +00003454- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
3455 by Musashi Tamura, tests by Marcin Bachry.
3456
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00003457- Issue #1983: Fix functions taking or returning a process identifier to use
3458 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
3459 a process identifier type wider than the standard C integer type.
3460
R. David Murray87e20742009-05-23 01:30:26 +00003461- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
3462 Patch by Farhan Ahmad, test by Marcin Bachry.
3463
Antoine Pitrou6e610062009-05-15 17:04:50 +00003464- Issue #2116: Weak references and weak dictionaries now support copy()ing and
3465 deepcopy()ing.
3466
Antoine Pitrouc1d09362009-05-15 12:15:51 +00003467- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
3468
Antoine Pitrou37d1c182009-05-14 21:54:00 +00003469- Issue #5918: Fix a crash in the parser module.
3470
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00003471- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
3472
Antoine Pitroue4501852009-05-14 18:55:55 +00003473- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
3474 library. This means, for example, that opening an UTF-16 text file in
3475 append mode doesn't add a BOM at the end of the file if the file isn't
3476 empty.
3477
R. David Murray74b89242009-05-13 17:33:03 +00003478- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
3479 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
3480 corrects a pydoc regression.
3481
Georg Brandl5f90d792010-08-01 22:31:05 +00003482- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00003483 now it does. This also means getfp method now returns the real fp.
3484
Benjamin Peterson932073a2009-05-23 16:14:33 +00003485Installation
3486------------
3487
3488- Issue #6047: fullinstall has been removed because Python 3's executable will
3489 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00003490
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00003491- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00003515- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00003516 tests on darwin even when the OS was installed on a case-sensitive
3517 filesystem. Also fixed tests that should not be run when
3518 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00003525
3526Core and Builtins
3527-----------------
3528
Mark Dickinson865e01a2009-05-07 16:37:01 +00003529- Issue #5914: Add new C API function PyOS_string_to_double, and
3530 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3531
Eric Smith741191f2009-05-06 13:08:15 +00003532- Issue #3382: float.__format__, complex.__format__, and %-formatting
3533 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
3534 affects nan -> NAN and inf -> INF.
3535
Mark Hammond5a607a32009-05-06 08:04:54 +00003536- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
3537 in all operations, including splitdrive, split, etc. splitunc() now issues
3538 a PendingDeprecation warning.
3539
Eric Smith63376222009-05-05 14:04:18 +00003540- Issue #5920: For float.__format__, change the behavior with the
3541 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
3542 to be like 'g' but with at least one decimal point and with a
3543 default precision of 12. Previously, the behavior the same but with
3544 a default precision of 6. This more closely matches str(), and
3545 reduces surprises when adding alignment flags to the empty
3546 presentation type. This also affects the new complex.__format__ in
3547 the same way.
3548
Martin v. Löwis011e8422009-05-05 04:43:17 +00003549- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
3550
R. David Murrayb18500d2009-05-04 22:59:07 +00003551- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3552 shadowed by classtype's, even if it was None. property now
3553 inserts the __doc__ into the subclass instance __dict__.
3554
Antoine Pitrou244651a2009-05-04 18:56:13 +00003555- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
3556 sequences. Patch by Nick Barnes and Victor Stinner.
3557
Martin v. Löwise0a2b722009-05-10 08:08:56 +00003558- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00003559
Benjamin Petersond2e0c792009-05-01 20:40:59 +00003560- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3561 received a new method, detach(). detach() disconnects the underlying stream
3562 from the buffer or text IO and returns it.
3563
Mark Dickinson33841c32009-05-01 15:37:04 +00003564- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3565 floats with absolute value over 1e50. Also remove length
3566 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3567 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00003568
Eric Smith741191f2009-05-06 13:08:15 +00003569- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003570 format(complex(1, 2./3), '.5') now produces a sensible result.
3571
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003572- Issue #5864: Fix empty format code formatting for floats so that it
3573 never gives more than the requested number of significant digits.
3574
Eric Smith6dc46f52009-04-27 20:39:49 +00003575- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
3576 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
3577
Eric Smithcc32a112009-04-26 21:35:14 +00003578- Issue #5835: Deprecate PyOS_ascii_formatd.
3579
Martin v. Löwis71efeb72009-04-26 01:02:07 +00003580- Issue #4971: Fix titlecase for characters that are their own
3581 titlecase, but not their own uppercase.
3582
Benjamin Peterson193152c2009-04-25 01:08:45 +00003583- Issue #5283: Setting __class__ in __del__ caused a segfault.
3584
Mark Dickinsonad476da2009-04-23 19:14:16 +00003585- Issue #5816: complex(repr(z)) now recovers z exactly, even when
3586 z involves nans, infs or negative zeros.
3587
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003588- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003589
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003590- Issue #1869 (and many duplicates): make round(x, n) correctly
3591 rounded for a float x, by using the decimal <-> binary conversions
3592 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3593 consistently agrees with format(x, '.2f').
3594
Benjamin Petersonae937c02009-04-18 20:54:08 +00003595- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3596 some builtin types.
3597
Eric Smith0923d1d2009-04-16 20:16:10 +00003598- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3599
Eric Smith35e84722009-04-16 20:21:28 +00003600- Issue #5515: str.format() type 'n' combined with commas and leading
3601 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003602
3603- Implement PEP 378, Format Specifier for Thousands Separator, for
3604 floats.
3605
Mark Dickinson3370cce2009-04-17 22:40:53 +00003606- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003607 1e11, not 1e12. This avoids printing 13 significant digits in
3608 situations where only 12 of them are correct. Example problem
3609 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3610 long time.)
3611
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003612- Issue #1580: On most platforms, use a 'short' float repr: for a
3613 finite float x, repr(x) now outputs a string based on the shortest
3614 sequence of decimal digits that rounds to x. Previous behaviour was
3615 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003616 Another minor difference is that the new repr switches to
3617 exponential notation at 1e16 instead of the previous 1e17; this
3618 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003619
3620 There's a new sys attribute sys.float_repr_style, which takes
3621 the value 'short' to indicate that we're using short float repr,
3622 and 'legacy' if the short float repr isn't available for one
3623 reason or another.
3624
3625 The float repr change involves incorporating David Gay's 'perfect
3626 rounding' code into the Python core (it's in Python/dtoa.c). As a
3627 secondary consequence, all string-to-float and float-to-string
3628 conversions (including all float formatting operations) will be
3629 correctly rounded on these platforms.
3630
Georg Brandl5f90d792010-08-01 22:31:05 +00003631 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003632 this change does not apply.
3633
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003634- Issue #5759: float() didn't call __float__ on str subclasses.
3635
Georg Brandlabc38772009-04-12 15:51:51 +00003636- The string.maketrans() function is deprecated; there is a new static method
3637 maketrans() on the bytes and bytearray classes. This removes confusion about
3638 the types string.maketrans() is supposed to work with, and mirrors the
3639 methods available on the str class.
3640
R. David Murraydc6da8a2009-04-09 22:16:43 +00003641- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
3642 its clarity and its speed.
3643
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003644- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00003645 to avoid compiler warnings.
3646
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003647- Issue #3739: The unicode-internal encoder now reports the number of characters
3648 consumed like any other encoder (instead of the number of bytes).

3662
Raymond Hettingereb816952009-05-29 01:22:18 +00003663- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003970- Issue #4935: The overflow checking code in the expandtabs() method common
3971 to str, bytes and bytearray could be optimized away by the compiler, letting
3972 the interpreter segfault instead of raising an error.
3973
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003974- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3975 __next__ method.
3976
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003977- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3978 function no longer attempt to call the __long__ slot to convert an object
3979 to an integer. Only the __int__ and __trunc__ slots are examined.

3984
Antoine Pitrouab868312009-01-10 15:40:25 +00003985- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3986 common cases are optimized thanks to a dedicated fast path and a moderate
3987 amount of loop unrolling.
3988
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003989- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3990 collecting the oldest generation) so that allocating lots of objects without
3991 destroying them does not show quadratic performance. Based on a proposal by
3992 Martin von Löwis at
3993 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3994
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003995- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003996 having been closed (for instance, a read() call could return some
3997 previously buffered data). Patch by Dmitry Vasiliev.
3998
Antoine Pitrou05608432009-01-09 18:53:14 +00003999- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4000 flag to work properly. Furthermore, when specifying -u, the text stdout
4001 and stderr streams have line-by-line buffering enabled (the default being
4002 to buffer arbitrary chunks of data).
4003
Raymond Hettinger35631532009-01-09 03:58:09 +00004004- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4005 instead of ints (reducing its size from 4 to 8 times thereby reducing
4006 Python's overall memory).
4007
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004008- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4009 an existing .py counterpart, override the co_filename attributes of all
4010 code objects if the original filename is obsolete (which can happen if the
4011 file has been renamed, moved, or if it is accessed through different paths).
4012 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4013
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004014- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4015 one byte. Also fixes the meaning of len() so that it returns the number of
4016 items, rather than the size in bytes.
4017
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004018- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004020- Issue #4747: When the terminal does not use utf-8, executing a script with
4021 non-ascii characters in its name could fail with a "SyntaxError: None" error.
4022
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004023- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

4027 did not get collected.
4028
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004029- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4030 where the tp_hash and tp_dict slots are both NULL.
4031
Georg Brandlccc47b62008-12-28 11:44:14 +00004032- Issue #4759: None is now allowed as the first argument of
4033 bytearray.translate(). It was always allowed for bytes.translate().
4034
Skip Montanaro80072cb2008-12-23 03:51:14 +00004035- Added test case to ensure attempts to read from a file opened for writing
4036 fail.
4037
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00004038- Issue #3106: Speedup some comparisons (str/str and int/int).

4042
Antoine Pitrou621601a2008-12-17 23:18:19 +00004043- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

4045 unreachable. Original patch by Neil Schemenauer.
4046

4048
Mark Dickinsonda2706b2008-12-11 18:03:03 +00004049- Issue #2173: When getting device encoding, check that return value of
4050 nl_langinfo is not the empty string. This was causing silent build
4051 failures on OS X.
4052
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00004053- Issue #4597: Fixed several opcodes that weren't always propagating
4054 exceptions.
4055
4056- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00004057 context manager returns a value that cannot be converted to a bool.
4058
Mark Dickinsonfd24b322008-12-06 15:33:31 +00004059- Issue #4445: Replace "sizeof(PyBytesObject)" with
4060 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
4061 bytes instances. On a typical machine this saves 3 bytes of memory
4062 (on average) per allocation of a bytes instance.
4063
Christian Heimesa872de52008-12-05 08:26:55 +00004064- Issue #4533: File read operation was dreadfully slow due to a slowly
4065 growing read buffer. Fixed by using the same growth rate algorithm as
4066 Python 2.x.
4067
Antoine Pitrou5504e892008-12-06 21:27:53 +00004068- Issue #4509: Various issues surrounding resize of bytearray objects to
4069 which there are buffer exports (e.g. memoryview instances).
4070
Georg Brandlf9734072008-12-07 15:30:06 +00004071- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
4072 method on file objects with closefd=False. The file descriptor is still
4073 kept open but the file object behaves like a closed file. The ``FileIO``
4074 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00004076- Issue #4569: Interpreter crash when mutating a memoryview with an item size

4082
Walter Dörwaldc1651a02009-05-03 22:55:55 +00004083- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
4084 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4085 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4086 of using the replace error handler in PyUnicode_DecodeUTF8().

4407 do an explicit seek to the end of file (so that e.g. tell() returns the
