Ezio Melotti25bc0192010-07-03 05:18:50 +000033- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
34 start byte and the continuation byte(s) are now considered invalid, instead
35 of the number of bytes specified by the start byte.
36 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
37 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
38 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
39 Previous versions returned a single u'\ufffd'.

Mark Dickinsonece06972010-05-04 14:37:14 +0000314- Issue #8567: Fix precedence of signals in Decimal module: when a
315 Decimal operation raises multiple signals and more than one of those
316 signals is trapped, the specification determines the order in which
317 the signals should be handled. In many cases this order wasn't
318 being followed, leading to the wrong Python exception being raised.

352 original socket wasn't retained (instead, a socket with a positive timeout
353 would be turned into a non-blocking SSL socket).
354
Antoine Pitrouec146182010-04-24 21:30:20 +0000355- Issue #5103: SSL handshake would ignore the socket timeout and block

Mark Dickinson865e01a2009-05-07 16:37:01 +00001411- Issue #5914: Add new C API function PyOS_string_to_double, and
1412 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1413
Eric Smith741191f2009-05-06 13:08:15 +00001414- Issue #3382: float.__format__, complex.__format__, and %-formatting
1415 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1416 affects nan -> NAN and inf -> INF.
1417
Mark Hammond5a607a32009-05-06 08:04:54 +00001418- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1419 in all operations, including splitdrive, split, etc. splitunc() now issues
1420 a PendingDeprecation warning.
1421
Eric Smith63376222009-05-05 14:04:18 +00001422- Issue #5920: For float.__format__, change the behavior with the
1423 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1424 to be like 'g' but with at least one decimal point and with a
1425 default precision of 12. Previously, the behavior the same but with
1426 a default precision of 6. This more closely matches str(), and
1427 reduces surprises when adding alignment flags to the empty
1428 presentation type. This also affects the new complex.__format__ in
1429 the same way.
1430
Martin v. Löwis011e8422009-05-05 04:43:17 +00001431- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1434 shadowed by classtype's, even if it was None. property now
1435 inserts the __doc__ into the subclass instance __dict__.
1436
Antoine Pitrou244651a2009-05-04 18:56:13 +00001437- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

1439
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001440- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001442- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1443 received a new method, detach(). detach() disconnects the underlying stream
1444 from the buffer or text IO and returns it.
1445
Mark Dickinson33841c32009-05-01 15:37:04 +00001446- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1447 floats with absolute value over 1e50. Also remove length
1448 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

1455 never gives more than the requested number of significant digits.
1456
Eric Smith6dc46f52009-04-27 20:39:49 +00001457- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1466
Mark Dickinsonad476da2009-04-23 19:14:16 +00001467- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1468 z involves nans, infs or negative zeros.
1469
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001470- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001471
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001472- Issue #1869 (and many duplicates): make round(x, n) correctly
1473 rounded for a float x, by using the decimal <-> binary conversions
1474 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1475 consistently agrees with format(x, '.2f').
1476
Benjamin Petersonae937c02009-04-18 20:54:08 +00001477- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1478 some builtin types.
1479
Eric Smith0923d1d2009-04-16 20:16:10 +00001480- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1481
Eric Smith35e84722009-04-16 20:21:28 +00001482- Issue #5515: str.format() type 'n' combined with commas and leading
1483 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001484
1485- Implement PEP 378, Format Specifier for Thousands Separator, for
1486 floats.
1487
Mark Dickinson3370cce2009-04-17 22:40:53 +00001488- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001489 1e11, not 1e12. This avoids printing 13 significant digits in
1490 situations where only 12 of them are correct. Example problem
1491 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1492 long time.)
1493
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001494- Issue #1580: On most platforms, use a 'short' float repr: for a
1495 finite float x, repr(x) now outputs a string based on the shortest
1496 sequence of decimal digits that rounds to x. Previous behaviour was
1497 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001498 Another minor difference is that the new repr switches to
1499 exponential notation at 1e16 instead of the previous 1e17; this
1500 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001501
1502 There's a new sys attribute sys.float_repr_style, which takes
1503 the value 'short' to indicate that we're using short float repr,
1504 and 'legacy' if the short float repr isn't available for one
1505 reason or another.
1506
1507 The float repr change involves incorporating David Gay's 'perfect
1508 rounding' code into the Python core (it's in Python/dtoa.c). As a
1509 secondary consequence, all string-to-float and float-to-string
1510 conversions (including all float formatting operations) will be
1511 correctly rounded on these platforms.
1512
Georg Brandl442d3b32010-08-01 22:33:12 +00001513 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001514 this change does not apply.
1515
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001516- Issue #5759: float() didn't call __float__ on str subclasses.
1517
Georg Brandlabc38772009-04-12 15:51:51 +00001518- The string.maketrans() function is deprecated; there is a new static method
1519 maketrans() on the bytes and bytearray classes. This removes confusion about
1520 the types string.maketrans() is supposed to work with, and mirrors the
1521 methods available on the str class.
1522
R. David Murraydc6da8a2009-04-09 22:16:43 +00001523- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1686
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001687- Issue #4688: Add a heuristic so that tuples and dicts containing only
1688 untrackable objects are not tracked by the garbage collector. This can
1689 reduce the size of collections and therefore the garbage collection overhead
1690 on long-running programs, depending on their particular use of datatypes.

1698 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1699 --enable-big-digits option to configure, which overrides the
1700 default. Add sys.int_info structseq to provide information about
1701 the internal format.

1704 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1705 and sizeof(Py_UNICODE) == 2.
1706
Eric Smith8ec90442009-03-14 12:29:34 +00001707- Issue #5237: Allow auto-numbered fields in str.format(). For

1756
Benjamin Peterson59406a92009-03-26 17:10:29 +00001757- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1758 io.BufferedRandom have been deprecated for removal in Python 3.2.
1759
Lars Gustäbel42e00912009-03-22 20:34:29 +00001760- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1761 forever on incomplete input. That caused tarfile.open() to hang when used
1762 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1783 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001784 struct.error instead of returning b'\xff\xff\xff\xff'. The
1785 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1786 have been removed from the struct module.

1805 contained non ascii character on windows.
1806
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001807- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1808 source has already been decoded into str.
1809

1811 rotating the object pointer by 4 bits to the right.
1812
Mark Dickinson87ec0852009-02-09 17:15:59 +00001813- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1814 it now forces its argument to double before testing for infinity.
1815
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001816- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001825
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001826- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001827 were suppressing all exceptions. These include list() and bytearray().

1830 Previously it returned a float.
1831
Antoine Pitroub52ec782009-01-25 16:34:23 +00001832- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1833 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1834 evaluation loop is compiled with a new dispatch mechanism which gives
1835 speedups of up to 20%, depending on the system, on various benchmarks.
1836
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001837- Issue #4874: Most builtin decoders now reject unicode input.

1843
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001844- Issue #4838: When a module is deallocated, free the memory backing the
1845 optional module state data.
1846
Mark Dickinson8055afd2009-01-17 10:04:45 +00001847- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1848 type to (void *).
1849
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001850- Issue #4935: The overflow checking code in the expandtabs() method common
1851 to str, bytes and bytearray could be optimized away by the compiler, letting
1852 the interpreter segfault instead of raising an error.
1853
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001854- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1855 __next__ method.
1856
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001857- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1858 function no longer attempt to call the __long__ slot to convert an object
1859 to an integer. Only the __int__ and __trunc__ slots are examined.
1860
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001861- Issue #4893: Use NT threading on CE.
1862

1864
Antoine Pitrouab868312009-01-10 15:40:25 +00001865- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1866 common cases are optimized thanks to a dedicated fast path and a moderate
1867 amount of loop unrolling.
1868
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001869- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1870 collecting the oldest generation) so that allocating lots of objects without
1871 destroying them does not show quadratic performance. Based on a proposal by
1872 Martin von Löwis at
1873 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1874
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001875- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001876 having been closed (for instance, a read() call could return some
1877 previously buffered data). Patch by Dmitry Vasiliev.
1878
Antoine Pitrou05608432009-01-09 18:53:14 +00001879- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1880 flag to work properly. Furthermore, when specifying -u, the text stdout
1881 and stderr streams have line-by-line buffering enabled (the default being
1882 to buffer arbitrary chunks of data).
1883
Raymond Hettinger35631532009-01-09 03:58:09 +00001884- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1885 instead of ints (reducing its size from 4 to 8 times thereby reducing
1886 Python's overall memory).
1887
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001888- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1889 an existing .py counterpart, override the co_filename attributes of all
1890 code objects if the original filename is obsolete (which can happen if the
1891 file has been renamed, moved, or if it is accessed through different paths).
1892 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1893
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001894- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1895 one byte. Also fixes the meaning of len() so that it returns the number of
1896 items, rather than the size in bytes.
1897
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001898- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1899
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001900- Issue #4747: When the terminal does not use utf-8, executing a script with
1901 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1902
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001903- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001904 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001905
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001906- Issue #3680: Reference cycles created through a dict, set or deque iterator
1907 did not get collected.
1908
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001909- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1910 where the tp_hash and tp_dict slots are both NULL.
1911
Georg Brandlccc47b62008-12-28 11:44:14 +00001912- Issue #4759: None is now allowed as the first argument of
1913 bytearray.translate(). It was always allowed for bytes.translate().
1914
Skip Montanaro80072cb2008-12-23 03:51:14 +00001915- Added test case to ensure attempts to read from a file opened for writing
1916 fail.
1917
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001918- Issue #3106: Speedup some comparisons (str/str and int/int).

1922
Antoine Pitrou621601a2008-12-17 23:18:19 +00001923- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1924 print elapsed times, not only when some objects are uncollectable /
1925 unreachable. Original patch by Neil Schemenauer.
1926
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001927- Issue #3439: Add a bit_length method to int.
1928
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001929- Issue #2173: When getting device encoding, check that return value of
1930 nl_langinfo is not the empty string. This was causing silent build
1931 failures on OS X.
1932
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001933- Issue #4597: Fixed several opcodes that weren't always propagating
1934 exceptions.
1935
1936- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001937 context manager returns a value that cannot be converted to a bool.
1938
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001939- Issue #4445: Replace "sizeof(PyBytesObject)" with
1940 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1941 bytes instances. On a typical machine this saves 3 bytes of memory
1942 (on average) per allocation of a bytes instance.
1943
Christian Heimesa872de52008-12-05 08:26:55 +00001944- Issue #4533: File read operation was dreadfully slow due to a slowly
1945 growing read buffer. Fixed by using the same growth rate algorithm as
1946 Python 2.x.
1947
Antoine Pitrou5504e892008-12-06 21:27:53 +00001948- Issue #4509: Various issues surrounding resize of bytearray objects to
1949 which there are buffer exports (e.g. memoryview instances).
1950
Georg Brandlf9734072008-12-07 15:30:06 +00001951- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1952 method on file objects with closefd=False. The file descriptor is still
1953 kept open but the file object behaves like a closed file. The ``FileIO``
1954 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001955
Antoine Pitroubc420402008-12-07 20:14:49 +00001956- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1962
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001963- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1964 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1965 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1966 of using the replace error handler in PyUnicode_DecodeUTF8().
