914 that would raise SystemError.
915
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000916- Issue #5982: staticmethod and classmethod now expose the wrapped
917 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000922- Issue #5829: complex("1e500") no longer raises OverflowError. This
923 makes it consistent with float("1e500") and interpretation of real
924 and imaginary literals.
925
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000926- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

931 (1) inf and nan strings with trailing whitespace were incorrectly
932 rejected; (2) parsing of strings representing infinities and nans
933 was locale aware; and (3) the interpretation of fromhex('-nan')
934 didn't match that of float('-nan').

947 arguments for strings with a space in them.
948
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000949- collections.namedtuple() was not working with the following field
950 names: cls, self, tuple, itemgetter, and property.
951
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000952- In unittest, using a skipping decorator on a class is now equivalent to

954
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000955- Issue #6050: Don't fail extracting a directory from a zipfile if
956 the directory already exists.
957
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000958- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
959 than an int, which makes some operations possible under 64-bit Linux (e.g.
960 DN_MULTISHOT with F_NOTIFY).
961
Antoine Pitrou716c4442009-05-23 19:04:03 +0000962- Issue #5761: Add the name of the underlying file to the repr() of various

969 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
970 a process identifier type wider than the standard C integer type.
971
R. David Murray87e20742009-05-23 01:30:26 +0000972- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

983
Antoine Pitroue4501852009-05-14 18:55:55 +0000984- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
985 library. This means, for example, that opening an UTF-16 text file in
986 append mode doesn't add a BOM at the end of the file if the file isn't
987 empty.
988
R. David Murray74b89242009-05-13 17:33:03 +0000989- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001036
1037Core and Builtins
1038-----------------
1039
Mark Dickinson865e01a2009-05-07 16:37:01 +00001040- Issue #5914: Add new C API function PyOS_string_to_double, and
1041 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1042
Eric Smith741191f2009-05-06 13:08:15 +00001043- Issue #3382: float.__format__, complex.__format__, and %-formatting
1044 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1045 affects nan -> NAN and inf -> INF.
1046
Mark Hammond5a607a32009-05-06 08:04:54 +00001047- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1048 in all operations, including splitdrive, split, etc. splitunc() now issues
1049 a PendingDeprecation warning.
1050
Eric Smith63376222009-05-05 14:04:18 +00001051- Issue #5920: For float.__format__, change the behavior with the
1052 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1053 to be like 'g' but with at least one decimal point and with a
1054 default precision of 12. Previously, the behavior the same but with
1055 a default precision of 6. This more closely matches str(), and
1056 reduces surprises when adding alignment flags to the empty
1057 presentation type. This also affects the new complex.__format__ in
1058 the same way.
1059
Martin v. Löwis011e8422009-05-05 04:43:17 +00001060- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1061
R. David Murrayb18500d2009-05-04 22:59:07 +00001062- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1063 shadowed by classtype's, even if it was None. property now
1064 inserts the __doc__ into the subclass instance __dict__.
1065
Antoine Pitrou244651a2009-05-04 18:56:13 +00001066- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1067 sequences. Patch by Nick Barnes and Victor Stinner.
1068
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001069- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001070
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001071- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1072 received a new method, detach(). detach() disconnects the underlying stream
1073 from the buffer or text IO and returns it.
1074
Mark Dickinson33841c32009-05-01 15:37:04 +00001075- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1076 floats with absolute value over 1e50. Also remove length
1077 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1078 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001079
Eric Smith741191f2009-05-06 13:08:15 +00001080- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001081 format(complex(1, 2./3), '.5') now produces a sensible result.
1082
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001083- Issue #5864: Fix empty format code formatting for floats so that it
1084 never gives more than the requested number of significant digits.
1085
Eric Smith6dc46f52009-04-27 20:39:49 +00001086- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1087 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1088
Eric Smithcc32a112009-04-26 21:35:14 +00001089- Issue #5835: Deprecate PyOS_ascii_formatd.
1090
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001091- Issue #4971: Fix titlecase for characters that are their own
1092 titlecase, but not their own uppercase.
1093
Benjamin Peterson193152c2009-04-25 01:08:45 +00001094- Issue #5283: Setting __class__ in __del__ caused a segfault.
1095
Mark Dickinsonad476da2009-04-23 19:14:16 +00001096- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1097 z involves nans, infs or negative zeros.
1098
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001099- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001100
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001101- Issue #1869 (and many duplicates): make round(x, n) correctly
1102 rounded for a float x, by using the decimal <-> binary conversions
1103 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1104 consistently agrees with format(x, '.2f').
1105
Benjamin Petersonae937c02009-04-18 20:54:08 +00001106- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1107 some builtin types.
1108
Eric Smith0923d1d2009-04-16 20:16:10 +00001109- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1110
Eric Smith35e84722009-04-16 20:21:28 +00001111- Issue #5515: str.format() type 'n' combined with commas and leading
1112 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001113
1114- Implement PEP 378, Format Specifier for Thousands Separator, for
1115 floats.
1116
Mark Dickinson3370cce2009-04-17 22:40:53 +00001117- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001118 1e11, not 1e12. This avoids printing 13 significant digits in
1119 situations where only 12 of them are correct. Example problem
1120 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1121 long time.)
1122
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001123- Issue #1580: On most platforms, use a 'short' float repr: for a
1124 finite float x, repr(x) now outputs a string based on the shortest
1125 sequence of decimal digits that rounds to x. Previous behaviour was
1126 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001127 Another minor difference is that the new repr switches to
1128 exponential notation at 1e16 instead of the previous 1e17; this
1129 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001130
1131 There's a new sys attribute sys.float_repr_style, which takes
1132 the value 'short' to indicate that we're using short float repr,
1133 and 'legacy' if the short float repr isn't available for one
1134 reason or another.
1135
1136 The float repr change involves incorporating David Gay's 'perfect
1137 rounding' code into the Python core (it's in Python/dtoa.c). As a
1138 secondary consequence, all string-to-float and float-to-string
1139 conversions (including all float formatting operations) will be
1140 correctly rounded on these platforms.
1141
1142 See issue 1580 discussions for details of platforms for which
1143 this change does not apply.
1144
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001145- Issue #5759: float() didn't call __float__ on str subclasses.
1146
Georg Brandlabc38772009-04-12 15:51:51 +00001147- The string.maketrans() function is deprecated; there is a new static method
1148 maketrans() on the bytes and bytearray classes. This removes confusion about
1149 the types string.maketrans() is supposed to work with, and mirrors the
1150 methods available on the str class.
1151
R. David Murraydc6da8a2009-04-09 22:16:43 +00001152- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1153 its clarity and its speed.
1154
Matthias Klose091c7b12009-04-07 13:24:27 +00001155- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1156 to avoid compiler warnings.
1157
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001158- Issue #3739: The unicode-internal encoder now reports the number of characters
1159 consumed like any other encoder (instead of the number of bytes).

Mark Dickinson8055afd2009-01-17 10:04:45 +00001476- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1477 type to (void *).
1478
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001479- Issue #4935: The overflow checking code in the expandtabs() method common
1480 to str, bytes and bytearray could be optimized away by the compiler, letting
1481 the interpreter segfault instead of raising an error.
1482
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001483- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1484 __next__ method.
1485
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001486- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1487 function no longer attempt to call the __long__ slot to convert an object
1488 to an integer. Only the __int__ and __trunc__ slots are examined.
1489
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001490- Issue #4893: Use NT threading on CE.
1491
Martin v. Löwisec59d042009-01-12 07:59:10 +00001492- Issue #4915: Port sysmodule to Windows CE.
1493
Antoine Pitrouab868312009-01-10 15:40:25 +00001494- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1495 common cases are optimized thanks to a dedicated fast path and a moderate
1496 amount of loop unrolling.
1497
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001498- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1499 collecting the oldest generation) so that allocating lots of objects without
1500 destroying them does not show quadratic performance. Based on a proposal by
1501 Martin von Löwis at
1502 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1503
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001504- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001505 having been closed (for instance, a read() call could return some
1506 previously buffered data). Patch by Dmitry Vasiliev.
1507
Antoine Pitrou05608432009-01-09 18:53:14 +00001508- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1509 flag to work properly. Furthermore, when specifying -u, the text stdout
1510 and stderr streams have line-by-line buffering enabled (the default being
1511 to buffer arbitrary chunks of data).
1512
Raymond Hettinger35631532009-01-09 03:58:09 +00001513- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1514 instead of ints (reducing its size from 4 to 8 times thereby reducing
1515 Python's overall memory).
1516
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001517- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1518 an existing .py counterpart, override the co_filename attributes of all
1519 code objects if the original filename is obsolete (which can happen if the
1520 file has been renamed, moved, or if it is accessed through different paths).
1521 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1522
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001523- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1524 one byte. Also fixes the meaning of len() so that it returns the number of
1525 items, rather than the size in bytes.
1526
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001527- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1528
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001529- Issue #4747: When the terminal does not use utf-8, executing a script with
1530 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1531
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001532- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001533 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001535- Issue #3680: Reference cycles created through a dict, set or deque iterator
1536 did not get collected.
1537
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001538- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1539 where the tp_hash and tp_dict slots are both NULL.
1540
Georg Brandlccc47b62008-12-28 11:44:14 +00001541- Issue #4759: None is now allowed as the first argument of
1542 bytearray.translate(). It was always allowed for bytes.translate().
1543
Skip Montanaro80072cb2008-12-23 03:51:14 +00001544- Added test case to ensure attempts to read from a file opened for writing
1545 fail.
1546
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001547- Issue #3106: Speedup some comparisons (str/str and int/int).

1550 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1551
Antoine Pitrou621601a2008-12-17 23:18:19 +00001552- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1554 unreachable. Original patch by Neil Schemenauer.
1555
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001556- Issue #3439: Add a bit_length method to int.
1557
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001558- Issue #2173: When getting device encoding, check that return value of
1559 nl_langinfo is not the empty string. This was causing silent build
1560 failures on OS X.
1561
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001562- Issue #4597: Fixed several opcodes that weren't always propagating
1563 exceptions.
1564
1565- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001566 context manager returns a value that cannot be converted to a bool.
1567
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001568- Issue #4445: Replace "sizeof(PyBytesObject)" with
1569 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1570 bytes instances. On a typical machine this saves 3 bytes of memory
1571 (on average) per allocation of a bytes instance.
1572
Christian Heimesa872de52008-12-05 08:26:55 +00001573- Issue #4533: File read operation was dreadfully slow due to a slowly
1574 growing read buffer. Fixed by using the same growth rate algorithm as
1575 Python 2.x.
1576
Antoine Pitrou5504e892008-12-06 21:27:53 +00001577- Issue #4509: Various issues surrounding resize of bytearray objects to
1578 which there are buffer exports (e.g. memoryview instances).
1579
Georg Brandlf9734072008-12-07 15:30:06 +00001580- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1581 method on file objects with closefd=False. The file descriptor is still
1582 kept open but the file object behaves like a closed file. The ``FileIO``
1583 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001584
Antoine Pitroubc420402008-12-07 20:14:49 +00001585- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1591
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001592- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1593 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1594 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1595 of using the replace error handler in PyUnicode_DecodeUTF8().

1874 do an explicit seek to the end of file (so that e.g. tell() returns the
