Georg Brandl255abdd2011-01-16 14:17:26 +0000637 continuation line in the formatted value has no leading white space and looks
638 like a header. Since Generator uses Header to format all headers, this check
639 is made for all headers in any serialized message at serialization time. This
640 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000641
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000642- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +0000648- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Georg Brandl255abdd2011-01-16 14:17:26 +0000649 non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to 7bit-clean
650 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +0000651
R. David Murray6f0022d2011-01-07 21:57:25 +0000652- email.header.Header was incorrectly encoding folding white space when
Georg Brandl255abdd2011-01-16 14:17:26 +0000653 rfc2047-encoding header values with embedded newlines, leaving them without
654 folding whitespace. It now uses the continuation_ws, as it does for
655 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000657- Issue #1777412, #10827: Changed the rules for 2-digit years. The
658 time.asctime(), time.ctime() and time.strftime() functions will now format
659 any year when ``time.accept2dyear`` is False and will accept years >= 1000
660 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
661 supported by the OS. With Visual Studio or on Solaris, the year is limited to
662 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

1634Core and Builtins
1635-----------------
1636
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001637- Issue #10068: Global objects which have reference cycles with their module's
1638 dict are now cleared again. This causes issue #7140 to appear again.
1639
Victor Stinner257d38f2010-10-09 10:12:11 +00001640- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001641 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001642
Georg Brandl27a28582010-10-10 09:49:21 +00001643- ast.literal_eval() can now handle negative numbers. It is also a little more
1644 liberal in what it accepts without compromising the safety of the evaluation.
1645 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001646
Benjamin Peterson970d1882010-10-02 17:55:47 +00001647- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1648 result metaclasses can now be ABCs (see #9533).
1649
Victor Stinneraef57e32010-10-02 11:50:49 +00001650- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1651
Victor Stinner5593d8a2010-10-02 11:11:27 +00001652- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001653 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
1654 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00001655

Victor Stinner5593d8a2010-10-02 11:11:27 +00001657 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001658
Victor Stinner137c34c2010-09-29 10:25:54 +00001659- Issue #9979: Create function PyUnicode_AsWideCharString().
1660
Brett Cannon5305a992010-09-27 21:08:38 +00001661- Issue #7397: Mention that importlib.import_module() is probably what someone
1662 really wants to be using in __import__'s docstring.
1663
Georg Brandl27a28582010-10-10 09:49:21 +00001664- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1665 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00001666
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001667- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001668 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001669
Brian Curtine8e4b3b2010-09-23 20:04:14 +00001670- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1671
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001672- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1673 threads are still running. Instead, reinitialize the GIL on a second call to
1674 Py_Initialize().
1675
Georg Brandl27a28582010-10-10 09:49:21 +00001676- All SyntaxErrors now have a column offset and therefore a caret when the error
1677 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001678
Brett Cannonbc2eff32010-09-19 21:39:02 +00001679- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1680 module that was imported, but instead gets the module from sys.modules.
1681
Nick Coghlan37ee8502010-12-03 14:26:13 +00001682- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001683 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001684
Georg Brandl27a28582010-10-10 09:49:21 +00001685- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1686 with a non-empty format string. This is an effort to future-proof user
1687 code. If a derived class does not currently implement __format__ but later
1688 adds its own __format__, it would most likely break user code that had
1689 supplied a format string. This will be changed to a DeprecationWaring in
1690 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001691
Antoine Pitrou1df15362010-09-13 14:16:46 +00001692- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1693 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1694 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1695
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001696- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1697 functions from the libc caused the methods .upper() and lower() to become
1698 locale aware and created subtly wrong results.
1699
Georg Brandl27a28582010-10-10 09:49:21 +00001700- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1701 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001702
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001703- Issue #4617: Previously it was illegal to delete a name from the local
1704 namespace if it occurs as a free variable in a nested block. This limitation
1705 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1706
Georg Brandl27a28582010-10-10 09:49:21 +00001707- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1708 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1709 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1710 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001711
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001712- Issue #9757: memoryview objects get a release() method to release the
1713 underlying buffer (previously this was only done when deallocating the
1714 memoryview), and gain support for the context management protocol.
1715
Antoine Pitrou079ce542010-09-08 12:37:10 +00001716- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1717 thread-local storage key.
1718

1729 not in build_clib.
1730
Antoine Pitroudbec7802010-10-10 09:37:12 +00001731- Issue #9437: Fix building C extensions with non-default LDFLAGS.
1732
R. David Murray96fd54e2010-10-08 15:55:28 +00001733- Issue #4661: email can now parse bytes input and generate either converted
1734 7bit output or bytes output. Email version bumped to 5.1.0.
1735
Antoine Pitrou59fdd672010-10-08 10:37:08 +00001736- Issue #1589: Add ssl.match_hostname(), to help implement server identity
1737 verification for higher-level protocols.
1738
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00001739- Issue #9759: GzipFile now raises ValueError when an operation is attempted
1740 after the file is closed. Patch by Jeffrey Finkelstein.
1741
Éric Araujo6108bf52010-10-04 23:52:37 +00001742- Issue #9042: Fix interaction of custom translation classes and caching in
1743 gettext.
1744
Éric Araujoef777bd2010-10-05 00:04:20 +00001745- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001746 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001747 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001748 replacement for old handle_accept() and avoids the user to call accept()
1749 directly.
1750
Lars Gustäbel331b8002010-10-04 15:18:47 +00001751- Issue #9065: tarfile no longer uses "root" as the default for the uname and

1755 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00001756
R. David Murray5397e862010-10-02 15:58:26 +00001757- Issue #1050268: parseaddr now correctly quotes double quote and backslash
1758 characters that appear inside quoted strings in email addresses.
1759
Georg Brandl27a28582010-10-10 09:49:21 +00001760- Issue #10004: quoprimime no longer generates a traceback when confronted with
1761 invalid characters after '=' in a Q-encoded word.

Georg Brandl27a28582010-10-10 09:49:21 +00001763- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
1764 sending a 200 OK for the Expect: 100-continue request header.

1767 conforms to the philosophy of bytes and unicode separation in Python 3. A
1768 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00001770- Issue #9962: GzipFile now has the peek() method.
1771
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001772- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001773 retry the select() loop instead of bailing out. This is because select() can
1774 incorrectly report a socket as ready for reading (for example, if it received
1775 some data with an invalid checksum).

Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00001777- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00001849- Issue #9837: The read() method of ZipExtFile objects (as returned by
1850 ZipFile.open()) could return more bytes than requested.
1851
Georg Brandl27a28582010-10-10 09:49:21 +00001852- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
1853 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00001854
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001855- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001856 it possible for the user to create self-referencing ordered dictionaries which
1857 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001858 approach of using weakref proxies so that reference cycles never get created
1859 in the first place.
1860
Victor Stinnercb043522010-09-10 23:49:04 +00001861- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
1862 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00001863 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00001864
Georg Brandl27a28582010-10-10 09:49:21 +00001865- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
1866 environment variable to set the filesystem encoding at Python startup.
1867 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1868 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001869
Georg Brandl27a28582010-10-10 09:49:21 +00001870- Issue #9410: Various optimizations to the pickle module, leading to speedups
1871 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
1872 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00001873
Georg Brandl27a28582010-10-10 09:49:21 +00001874- The pprint module now supports printing OrderedDicts in their given order
1875 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00001877- Logging: Added QueueHandler class to facilitate logging usage with
1878 multiprocessing.
1879
Georg Brandl27a28582010-10-10 09:49:21 +00001880- Issue #9707: Rewritten reference implementation of threading.local which is
1881 friendlier towards reference cycles. This change is not normally visible
1882 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001883
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001884- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1885 still return the id of the parent process after it has exited. This process
1886 id may even have been reused by another unrelated process.
1887
Georg Brandl27a28582010-10-10 09:49:21 +00001888- Issue #9792: In case of connection failure, socket.create_connection() would
1889 swallow the exception and raise a new one, making it impossible to fetch the
1890 original errno, or to filter timeout errors. Now the original error is
1891 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00001893- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1894 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1895 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001897- Updates to the random module:
1898
Georg Brandl27a28582010-10-10 09:49:21 +00001899 * Document which parts of the module are guaranteed to stay the same across
1900 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001901
Georg Brandl27a28582010-10-10 09:49:21 +00001902 * Update the seed() method to use all of the bits in a string instead of just
1903 the hash value. This makes better use of the seed value and assures the
1904 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001905
Georg Brandl27a28582010-10-10 09:49:21 +00001906 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1907 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1908 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001909
1910 * Improved documentation of arguments to randrange(). Issue #9379.

1916 cases now also have assertWarns and assertWarnsRegexp methods to check that a
1917 given warning type was triggered by the code under test.
Antoine Pitrou4bc12ef2010-09-06 19:25:46 +00001918
Georg Brandl27a28582010-10-10 09:49:21 +00001919- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
1920 their contents without duplicating them. The view is both readable and
1921 writable.

Brian Curtin62857742010-09-06 17:07:27 +00001923- Issue #7566: Implement os.path.sameopenfile for Windows.
1924
Antoine Pitrou0d739d72010-09-05 23:01:12 +00001925- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00001926 unsupported operation is attempted (for example, writing to a file open only
1927 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00001929- hashlib has two new constant attributes: algorithms_guaranteed and
1930 algorithms_avaiable that respectively list the names of hash algorithms
1931 guaranteed to exist in all Python implementations and the names of hash
1932 algorithms available in the current process.
1933
Brian Quinlanaf38dc52010-09-21 12:28:43 +00001934- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl27a28582010-10-10 09:49:21 +00001948- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
1949 wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
1950 and the interpreter under test.

Georg Brandl649971e2010-09-05 17:06:50 +00002037- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2038 now removed, since their effect was inexistent in 3.x (the default encoding is
2039 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002040
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002041- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

2061 return characters from the full Unicode range, even on narrow unicode builds
2062 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2063 in Python is that unicodedata.numeric() now returns the correct value for
2064 large code points, and repr() may consider more characters as printable.
2065
Victor Stinner6c00c142010-08-17 23:37:11 +00002066- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Victor Stinner47fcb5b2010-08-13 23:59:58 +00002082- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002083 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2084 objects are output as-is.

Ezio Melotti57221d02010-07-01 07:32:02 +00002444- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002445 start byte and the continuation byte(s) are now considered invalid, instead of
2446 the number of bytes specified by the start byte. E.g.:
2447 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2448 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2449 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2450 returned a single u'\ufffd'.

2465 dealing with unary minus applied to a constant. The removed code was mutating
2466 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00002470 error handlers, the decoder only supports "strict" and "ignore" error

2479
Georg Brandl62069d32010-07-31 08:56:11 +00002480- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002481 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2482 location of the raised exception.
2483
Victor Stinner313a1202010-06-11 23:56:51 +00002484- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode

Georg Brandl62069d32010-07-31 08:56:11 +00002493- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2494 TypeError instead of giving a DeprecationWarning when a float is parsed using
2495 the 'L' code (for long long). (All other integer codes already raise
2496 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002497
Victor Stinner600d3be2010-06-10 12:00:55 +00002498- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2499 enable shortcuts for upper case encoding name. Add also a shortcut for
2500 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2501
Georg Brandl62069d32010-07-31 08:56:11 +00002502- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2503 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002504
2505- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002506 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002507 like bytearray.
2508
Georg Brandl62069d32010-07-31 08:56:11 +00002509- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002510 used anymore and it was never documented.
2511
Georg Brandl62069d32010-07-31 08:56:11 +00002512- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002516
Georg Brandl62069d32010-07-31 08:56:11 +00002517- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2518 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2519 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2520 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002521
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002522- Issue #8748: Fix two issues with comparisons between complex and integer
2523 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002524 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2525 (2) The comparison raised an OverflowError for large integers, leading to
2526 unpredictable exceptions when combining integers and complex objects in sets
2527 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002528

2531
Victor Stinner9ca9c252010-05-19 16:53:30 +00002532- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002533 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002534 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.

Georg Brandl62069d32010-07-31 08:56:11 +00002536- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2537 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002538
Victor Stinnerae6265f2010-05-15 16:27:27 +00002539- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2540 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002541 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002542 back to UTF-8.

2828
Alexander Belopolskyf0f45142010-08-11 17:31:17 +00002829- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
2830 variable argument list. `Py_VA_COPY` is equivalent to C99
2831 `va_copy`, but available on all python platforms.
2832
Mark Dickinsone6fc7402010-08-06 18:55:26 +00002833- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
2834 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
2835 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00002845- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00002846 function declaration, which was kept for backwards compatibility reasons, is
2847 now removed (the macro was introduced in 1997!).

2857 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2858 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002859 to match the behaviour of the other integer format codes.
2860

Georg Brandl62069d32010-07-31 08:56:11 +00002869- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
2870 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
2871 accessing the d_type and d_name members of structures using PyDescr_COMMON.

2885
Georg Brandl62069d32010-07-31 08:56:11 +00002886- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2887 allocator will be automatically disabled when running under Valgrind. This
2888 gives improved memory leak detection when running under Valgrind, while taking
2889 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00002964 simply clearing the entire cache on overflow to forgetting the least recently
2965 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00002966 applications that use a lot of regular expressions and limits the impact of
2967 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00002979- Issue #7989: Added pure python implementation of the `datetime` module. The C
2980 module is renamed to `_datetime` and if available, overrides all classes
2981 defined in datetime with fast C impementation. Python implementation is based
2982 on the original python prototype for the datetime module by Tim Peters with
2983 minor modifications by the PyPy project. The test suite now tests `datetime`
2984 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00003264- Issue #8524: When creating an SSL socket, the timeout value of the original
3265 socket wasn't retained (instead, a socket with a positive timeout would be
3266 turned into a non-blocking SSL socket).

Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003268- Issue #5103: SSL handshake would ignore the socket timeout and block
3269 indefinitely if the other end didn't respond.
3270
Georg Brandl62069d32010-07-31 08:56:11 +00003271- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00003339- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003340 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003341 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003365- Add functools.total_ordering() and functools.cmp_to_key().
3366
Georg Brandl62069d32010-07-31 08:56:11 +00003367- Issue #8257: The Decimal construct now accepts a float instance directly,
3368 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003369
3370 >>> Decimal(1.1)
3371 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00003376- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3377 InvalidOperation instead of returning False. (Comparisons involving a quiet
3378 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3379 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003380
Georg Brandl62069d32010-07-31 08:56:11 +00003381- Issue #2531: Comparison operations between floats and Decimal instances now
3382 return a result based on the numeric values of the operands; previously they
3383 returned an arbitrary result based on the relative ordering of id(float) and
3384 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3385 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003386
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003387- Added a subtract() method to collections.Counter().
3388
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003389- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003390 argument `-` which tells it to read files to compile from stdin. Each line is
3391 read on demand and the named file is compiled immediately. (Original patch by
3392 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003394- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3395 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003396 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00003398- Comparisons using one of <, <=, >, >= between a complex instance and a
3399 Fractions instance now raise TypeError instead of returning True/False. This
3400 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3401 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003444- The internals of the subprocess module on POSIX systems have been replaced by
3445 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3446 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003448- subprocess.Popen now has restore_signals and start_new_session features. The
3449 default of restore_signals=True is a new behavior compared to earlier Python
3450 versions. This means that signals such as SIGPIPE are not ignored by default
3451 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003706- Issue #6816: runpy now provides a run_path function that allows Python code to
3707 execute file paths that refer to source or compiled Python files as well as
3708 zipfiles, directories and other valid sys.path entries that contain a
3709 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00003710 support the same flexibility as the CPython command line itself.

Antoine Pitrou434736a2009-11-10 18:46:01 +00003727- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00003728 default when instantiating a `threading.RLock` object. This makes recursive
3729 locks as fast as regular non-recursive locks (previously, they were slower by
3730 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00003749- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
3750 from stdin so that existing input does not confuse it and lead to incorrect
3751 entry or an IOError. It also properly flushes it afterwards to avoid the
3752 terminal echoing the input afterwards on OSes such as Solaris.

Mark Dickinsonfa41e602010-09-28 07:22:27 +00003939- Issue #9959: Tweak formula used for computing math.log of an integer,
3940 making it marginally more accurate for exact powers of 2.
3941
Mark Dickinsoncf28b952010-07-29 21:41:59 +00003942- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00003944- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00003945 compared to other unix systems. In particular, os.getgroups() does not reflect
3946 any changes made using os.setgroups() but basicly always returns the same
3947 information as the id command. os.getgroups() can now return more than 16
3948 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00003952- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
3953 struct.pack('>?')): if conversion to bool raised an exception then that
3954 exception wasn't properly propagated on machines where char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00003955

3957 they contain instances of old-style classes.
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00003958
Georg Brandl62069d32010-07-31 08:56:11 +00003959- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
3960 existing isinf and isnan functions.
Mark Dickinson8e0c9962010-07-11 17:38:24 +00003961
Georg Brandl62069d32010-07-31 08:56:11 +00003962- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
3963 R. Coombs.
Brian Curtind40e6f72010-07-08 21:39:08 +00003964
Benjamin Petersona9800a82010-07-07 19:04:48 +00003965- In struct.pack, correctly propogate exceptions from computing the truth of an
3966 object in the '?' format.

Alexander Belopolskya11d8c02010-07-06 23:19:45 +00003968- Issue #9000: datetime.timezone objects now have eval-friendly repr.
3969
Benjamin Petersonf751bc92010-07-02 13:46:42 +00003970- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
3971 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00003972
Georg Brandl62069d32010-07-31 08:56:11 +00003973- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
3974 Prior to this change, timezone adjustment in utctimetuple() could produce
3975 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
3976 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00003977
Georg Brandl62069d32010-07-31 08:56:11 +00003978- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
3979 directive. When the ``%z`` directive is present in the format string, an
3980 aware ``datetime`` object is returned with ``tzinfo`` bound to a
3981 ``datetime.timezone`` instance constructed from the parsed offset. If both
3982 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
3983 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00003984
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00003985- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00003986 implementing ``datetime.tzinfo`` interface. Instances of the new class,
3987 ``datetime.timezone``, return fixed name and UTC offset from their
3988 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
3989 returns ``None``. A class attribute, ``utc`` contains an instance
3990 representing the UTC timezone. Original patch by Rafe Kaplan.
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00003991
Georg Brandl62069d32010-07-31 08:56:11 +00003992- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
3993 includes documentation for the struct.Struct class.
Mark Dickinson4b80ef52010-06-12 15:17:02 +00003994
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00003995- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00003996 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00003997 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00003998
Georg Brandl62069d32010-07-31 08:56:11 +00003999- Issue #7384: If the system readline library is linked against ncurses, the
4000 curses module must be linked against ncurses as well. Otherwise it is not safe
4001 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00004002
Georg Brandl62069d32010-07-31 08:56:11 +00004003- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
4004 requiring a re-try in order to get the complete result.
Brian Curtin60853212010-05-26 17:43:50 +00004005
Georg Brandl62069d32010-07-31 08:56:11 +00004006- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4007 with an improved 'binary-split' algorithm that uses fewer multiplications and
4008 allows many of the multiplications to be performed using plain C integer
4009 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4010 arguments.
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00004011
Mark Dickinson85eacea2010-05-10 16:27:45 +00004012- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
4013 overflow checks in the audioop module.
4014
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004015- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4016 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004017 the result is now always correctly rounded, and is equivalent to ``td /
4018 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004019
Georg Brandl62069d32010-07-31 08:56:11 +00004020- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

4025
Mark Dickinsonc5935772010-04-03 15:54:36 +00004026- Issue #8300: When passing a non-integer argument to struct.pack with any
4027 integer format code, struct.pack first attempts to convert the non-integer
4028 using its __index__ method. If that method is non-existent or raises
4029 TypeError it goes on to try the __int__ method, as described below.
4030

4468
Eric Smith41669ca2009-05-23 14:23:22 +00004469- Issue #6089: Fixed str.format with certain invalid field specifiers
4470 that would raise SystemError.
4471
Raymond Hettinger2bcde142009-05-29 04:52:27 +00004472- Issue #5982: staticmethod and classmethod now expose the wrapped
4473 function with __func__.
4474
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00004475- Added support for multiple context managers in the same with-statement.
4476 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00004477
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00004478- Issue #5829: complex("1e500") no longer raises OverflowError. This
4479 makes it consistent with float("1e500") and interpretation of real
4480 and imaginary literals.
4481
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00004482- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

4485
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00004486- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
4487 (1) inf and nan strings with trailing whitespace were incorrectly
4488 rejected; (2) parsing of strings representing infinities and nans
4489 was locale aware; and (3) the interpretation of fromhex('-nan')
4490 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00004495- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
4496
R. David Murrayfb123912009-05-28 18:19:00 +00004497- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
4498
R. David Murray1f1b9d32009-05-27 20:56:59 +00004499- Issue #6121: pydoc now ignores leading and trailing spaces in the
4500 argument to the 'help' function.
4501
Georg Brandlfaf41492009-05-26 18:31:11 +00004502- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
4503 arguments for strings with a space in them.
4504
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00004505- collections.namedtuple() was not working with the following field
4506 names: cls, self, tuple, itemgetter, and property.
4507
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004508- In unittest, using a skipping decorator on a class is now equivalent to
4509 skipping every test on the class. The ClassTestSuite class has been removed.
4510
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004511- Issue #6050: Don't fail extracting a directory from a zipfile if
4512 the directory already exists.
4513
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004514- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4515 than an int, which makes some operations possible under 64-bit Linux (e.g.
4516 DN_MULTISHOT with F_NOTIFY).
4517
Antoine Pitrou716c4442009-05-23 19:04:03 +00004518- Issue #5761: Add the name of the underlying file to the repr() of various
4519 IO objects.
4520
R. David Murraycaa27b72009-05-23 18:49:56 +00004521- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4522 by Musashi Tamura, tests by Marcin Bachry.
4523
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004524- Issue #1983: Fix functions taking or returning a process identifier to use
4525 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4526 a process identifier type wider than the standard C integer type.
4527
R. David Murray87e20742009-05-23 01:30:26 +00004528- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

4539
Antoine Pitroue4501852009-05-14 18:55:55 +00004540- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4541 library. This means, for example, that opening an UTF-16 text file in
4542 append mode doesn't add a BOM at the end of the file if the file isn't
4543 empty.
4544
R. David Murray74b89242009-05-13 17:33:03 +00004545- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4546 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4547 corrects a pydoc regression.
4548
Georg Brandl5f90d792010-08-01 22:31:05 +00004549- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004550 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00004591*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00004592
4593Core and Builtins
4594-----------------
4595
Mark Dickinson865e01a2009-05-07 16:37:01 +00004596- Issue #5914: Add new C API function PyOS_string_to_double, and
4597 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4598
Eric Smith741191f2009-05-06 13:08:15 +00004599- Issue #3382: float.__format__, complex.__format__, and %-formatting
4600 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4601 affects nan -> NAN and inf -> INF.
4602
Mark Hammond5a607a32009-05-06 08:04:54 +00004603- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4604 in all operations, including splitdrive, split, etc. splitunc() now issues
4605 a PendingDeprecation warning.
4606
Eric Smith63376222009-05-05 14:04:18 +00004607- Issue #5920: For float.__format__, change the behavior with the
4608 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4609 to be like 'g' but with at least one decimal point and with a
4610 default precision of 12. Previously, the behavior the same but with
4611 a default precision of 6. This more closely matches str(), and
4612 reduces surprises when adding alignment flags to the empty
4613 presentation type. This also affects the new complex.__format__ in
4614 the same way.
4615
Martin v. Löwis011e8422009-05-05 04:43:17 +00004616- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4617
R. David Murrayb18500d2009-05-04 22:59:07 +00004618- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4619 shadowed by classtype's, even if it was None. property now
4620 inserts the __doc__ into the subclass instance __dict__.
4621
Antoine Pitrou244651a2009-05-04 18:56:13 +00004622- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4623 sequences. Patch by Nick Barnes and Victor Stinner.
4624
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004625- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004626
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004627- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4628 received a new method, detach(). detach() disconnects the underlying stream
4629 from the buffer or text IO and returns it.
4630
Mark Dickinson33841c32009-05-01 15:37:04 +00004631- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4632 floats with absolute value over 1e50. Also remove length
4633 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4634 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004635
Eric Smith741191f2009-05-06 13:08:15 +00004636- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004637 format(complex(1, 2./3), '.5') now produces a sensible result.
4638
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004639- Issue #5864: Fix empty format code formatting for floats so that it
4640 never gives more than the requested number of significant digits.
4641
Eric Smith6dc46f52009-04-27 20:39:49 +00004642- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4643 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4644
Eric Smithcc32a112009-04-26 21:35:14 +00004645- Issue #5835: Deprecate PyOS_ascii_formatd.
4646
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004647- Issue #4971: Fix titlecase for characters that are their own
4648 titlecase, but not their own uppercase.
4649
Benjamin Peterson193152c2009-04-25 01:08:45 +00004650- Issue #5283: Setting __class__ in __del__ caused a segfault.
4651
Mark Dickinsonad476da2009-04-23 19:14:16 +00004652- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4653 z involves nans, infs or negative zeros.
4654
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004655- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004656
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004657- Issue #1869 (and many duplicates): make round(x, n) correctly
4658 rounded for a float x, by using the decimal <-> binary conversions
4659 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4660 consistently agrees with format(x, '.2f').
4661
Benjamin Petersonae937c02009-04-18 20:54:08 +00004662- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4663 some builtin types.
4664
Eric Smith0923d1d2009-04-16 20:16:10 +00004665- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4666
Eric Smith35e84722009-04-16 20:21:28 +00004667- Issue #5515: str.format() type 'n' combined with commas and leading
4668 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004669
4670- Implement PEP 378, Format Specifier for Thousands Separator, for
4671 floats.
4672
Mark Dickinson3370cce2009-04-17 22:40:53 +00004673- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004674 1e11, not 1e12. This avoids printing 13 significant digits in
4675 situations where only 12 of them are correct. Example problem
4676 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4677 long time.)
4678
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004679- Issue #1580: On most platforms, use a 'short' float repr: for a
4680 finite float x, repr(x) now outputs a string based on the shortest
4681 sequence of decimal digits that rounds to x. Previous behaviour was
4682 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004683 Another minor difference is that the new repr switches to
4684 exponential notation at 1e16 instead of the previous 1e17; this
4685 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004686
4687 There's a new sys attribute sys.float_repr_style, which takes
4688 the value 'short' to indicate that we're using short float repr,
4689 and 'legacy' if the short float repr isn't available for one
4690 reason or another.
4691
4692 The float repr change involves incorporating David Gay's 'perfect
4693 rounding' code into the Python core (it's in Python/dtoa.c). As a
4694 secondary consequence, all string-to-float and float-to-string
4695 conversions (including all float formatting operations) will be
4696 correctly rounded on these platforms.
4697
Georg Brandl5f90d792010-08-01 22:31:05 +00004698 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004699 this change does not apply.
4700
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004701- Issue #5759: float() didn't call __float__ on str subclasses.
4702
Georg Brandlabc38772009-04-12 15:51:51 +00004703- The string.maketrans() function is deprecated; there is a new static method
4704 maketrans() on the bytes and bytearray classes. This removes confusion about
4705 the types string.maketrans() is supposed to work with, and mirrors the
4706 methods available on the str class.
4707
R. David Murraydc6da8a2009-04-09 22:16:43 +00004708- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4709 its clarity and its speed.
4710
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004711- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``

Mark Dickinsone94c6792009-02-02 20:36:42 +00005010 the type definition cmpfunc. The tp_compare slot has been renamed
5011 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005013- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005014 were suppressing all exceptions. These include list() and bytearray().
5015
Mark Dickinson1124e712009-01-28 21:25:58 +00005016- Issue #4707: round(x, n) now returns an integer if x is an integer.
5017 Previously it returned a float.
5018
Antoine Pitroub52ec782009-01-25 16:34:23 +00005019- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5020 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5021 evaluation loop is compiled with a new dispatch mechanism which gives
5022 speedups of up to 20%, depending on the system, on various benchmarks.
5023
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005024- Issue #4874: Most builtin decoders now reject unicode input.

5032 optional module state data.
5033
Mark Dickinson8055afd2009-01-17 10:04:45 +00005034- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005035 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005036
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005037- Issue #4935: The overflow checking code in the expandtabs() method common
5038 to str, bytes and bytearray could be optimized away by the compiler, letting
5039 the interpreter segfault instead of raising an error.
5040
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005041- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5042 __next__ method.
5043
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005044- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5045 function no longer attempt to call the __long__ slot to convert an object
5046 to an integer. Only the __int__ and __trunc__ slots are examined.

5051
Antoine Pitrouab868312009-01-10 15:40:25 +00005052- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5053 common cases are optimized thanks to a dedicated fast path and a moderate
5054 amount of loop unrolling.
5055
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005056- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5057 collecting the oldest generation) so that allocating lots of objects without
5058 destroying them does not show quadratic performance. Based on a proposal by
5059 Martin von Löwis at
5060 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5061
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005062- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005063 having been closed (for instance, a read() call could return some
5064 previously buffered data). Patch by Dmitry Vasiliev.
5065
Antoine Pitrou05608432009-01-09 18:53:14 +00005066- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5067 flag to work properly. Furthermore, when specifying -u, the text stdout
5068 and stderr streams have line-by-line buffering enabled (the default being
5069 to buffer arbitrary chunks of data).
5070
Raymond Hettinger35631532009-01-09 03:58:09 +00005071- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5072 instead of ints (reducing its size from 4 to 8 times thereby reducing
5073 Python's overall memory).
5074
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005075- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5076 an existing .py counterpart, override the co_filename attributes of all
5077 code objects if the original filename is obsolete (which can happen if the
5078 file has been renamed, moved, or if it is accessed through different paths).
5079 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5080
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005081- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5082 one byte. Also fixes the meaning of len() so that it returns the number of
5083 items, rather than the size in bytes.
5084
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005085- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5086
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005087- Issue #4747: When the terminal does not use utf-8, executing a script with
5088 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5089
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005090- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5094 did not get collected.
5095
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005096- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5097 where the tp_hash and tp_dict slots are both NULL.
5098
Georg Brandlccc47b62008-12-28 11:44:14 +00005099- Issue #4759: None is now allowed as the first argument of
5100 bytearray.translate(). It was always allowed for bytes.translate().
5101
Skip Montanaro80072cb2008-12-23 03:51:14 +00005102- Added test case to ensure attempts to read from a file opened for writing
5103 fail.
5104

5109
Antoine Pitrou621601a2008-12-17 23:18:19 +00005110- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00005116- Issue #2173: When getting device encoding, check that return value of
5117 nl_langinfo is not the empty string. This was causing silent build
5118 failures on OS X.
5119
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005120- Issue #4597: Fixed several opcodes that weren't always propagating
5121 exceptions.
5122
5123- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005124 context manager returns a value that cannot be converted to a bool.
5125
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005126- Issue #4445: Replace "sizeof(PyBytesObject)" with
5127 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5128 bytes instances. On a typical machine this saves 3 bytes of memory
5129 (on average) per allocation of a bytes instance.
5130
Christian Heimesa872de52008-12-05 08:26:55 +00005131- Issue #4533: File read operation was dreadfully slow due to a slowly
5132 growing read buffer. Fixed by using the same growth rate algorithm as
5133 Python 2.x.
5134
Antoine Pitrou5504e892008-12-06 21:27:53 +00005135- Issue #4509: Various issues surrounding resize of bytearray objects to
5136 which there are buffer exports (e.g. memoryview instances).
5137
Georg Brandlf9734072008-12-07 15:30:06 +00005138- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5139 method on file objects with closefd=False. The file descriptor is still
5140 kept open but the file object behaves like a closed file. The ``FileIO``
5141 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005150- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5151 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5152 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5153 of using the replace error handler in PyUnicode_DecodeUTF8().

5474 do an explicit seek to the end of file (so that e.g. tell() returns the
