52
Mark Dickinsonece06972010-05-04 14:37:14 +000053- Issue #8567: Fix precedence of signals in Decimal module: when a
54 Decimal operation raises multiple signals and more than one of those
55 signals is trapped, the specification determines the order in which
56 the signals should be handled. In many cases this order wasn't
57 being followed, leading to the wrong Python exception being raised.

89 would be turned into a non-blocking SSL socket).
90
Antoine Pitrouec146182010-04-24 21:30:20 +000091- Issue #5103: SSL handshake would ignore the socket timeout and block
92 indefinitely if the other end didn't respond.
93
94- The do_handshake() method of SSL objects now adjusts the blocking mode of
95 the SSL structure if necessary (as other methods already do).
96
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +000097- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
98 a non-infinite timeout. Also make that method friendlier with applications

113
Giampaolo Rodolàf5279402010-04-19 22:10:56 +0000114- Issue #4814: timeout parameter is now applied also for connections resulting

133
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000134- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
135 some methods (such as oss_mixer_device.fileno()) were not available.
136 Initial patch by Bertrand Janin.
137
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000138- Issue #7512: shutil.copystat() could raise an OSError when the filesystem

931Core and Builtins
932-----------------
933
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000934- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
935 of the command line.
936

940 that would raise SystemError.
941
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000942- Issue #5982: staticmethod and classmethod now expose the wrapped
943 function with __func__.
944
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000945- Added support for multiple context managers in the same with-statement.
946 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000948- Issue #5829: complex("1e500") no longer raises OverflowError. This
949 makes it consistent with float("1e500") and interpretation of real
950 and imaginary literals.
951
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000952- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
953
R. David Murraydd226ea2009-05-13 12:27:21 +0000954- Issue #5994: the marshal module now has docstrings.
955
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000956- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
957 (1) inf and nan strings with trailing whitespace were incorrectly
958 rejected; (2) parsing of strings representing infinities and nans
959 was locale aware; and (3) the interpretation of fromhex('-nan')
960 didn't match that of float('-nan').

968
R. David Murray1f1b9d32009-05-27 20:56:59 +0000969- Issue #6121: pydoc now ignores leading and trailing spaces in the
970 argument to the 'help' function.
971
Georg Brandlfaf41492009-05-26 18:31:11 +0000972- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
973 arguments for strings with a space in them.
974
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000975- collections.namedtuple() was not working with the following field
976 names: cls, self, tuple, itemgetter, and property.
977
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000978- In unittest, using a skipping decorator on a class is now equivalent to
979 skipping every test on the class. The ClassTestSuite class has been removed.
980
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000981- Issue #6050: Don't fail extracting a directory from a zipfile if
982 the directory already exists.
983
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000984- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
985 than an int, which makes some operations possible under 64-bit Linux (e.g.
986 DN_MULTISHOT with F_NOTIFY).
987
Antoine Pitrou716c4442009-05-23 19:04:03 +0000988- Issue #5761: Add the name of the underlying file to the repr() of various

992 by Musashi Tamura, tests by Marcin Bachry.
993
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000994- Issue #1983: Fix functions taking or returning a process identifier to use
995 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
996 a process identifier type wider than the standard C integer type.
997
R. David Murray87e20742009-05-23 01:30:26 +0000998- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1009
Antoine Pitroue4501852009-05-14 18:55:55 +00001010- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1011 library. This means, for example, that opening an UTF-16 text file in
1012 append mode doesn't add a BOM at the end of the file if the file isn't
1013 empty.
1014
R. David Murray74b89242009-05-13 17:33:03 +00001015- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1016 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1017 corrects a pydoc regression.
1018
R. David Murray99352742009-05-07 18:24:38 +00001019- Issue 5955: aifc's close method did not close the file it wrapped,
1020 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001058What's New in Python 3.1 beta 1?
1059================================
1060
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001061*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001062
1063Core and Builtins
1064-----------------
1065
Mark Dickinson865e01a2009-05-07 16:37:01 +00001066- Issue #5914: Add new C API function PyOS_string_to_double, and
1067 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1068
Eric Smith741191f2009-05-06 13:08:15 +00001069- Issue #3382: float.__format__, complex.__format__, and %-formatting
1070 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1071 affects nan -> NAN and inf -> INF.
1072
Mark Hammond5a607a32009-05-06 08:04:54 +00001073- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1074 in all operations, including splitdrive, split, etc. splitunc() now issues
1075 a PendingDeprecation warning.
1076
Eric Smith63376222009-05-05 14:04:18 +00001077- Issue #5920: For float.__format__, change the behavior with the
1078 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1079 to be like 'g' but with at least one decimal point and with a
1080 default precision of 12. Previously, the behavior the same but with
1081 a default precision of 6. This more closely matches str(), and
1082 reduces surprises when adding alignment flags to the empty
1083 presentation type. This also affects the new complex.__format__ in
1084 the same way.
1085
Martin v. Löwis011e8422009-05-05 04:43:17 +00001086- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1087
R. David Murrayb18500d2009-05-04 22:59:07 +00001088- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1089 shadowed by classtype's, even if it was None. property now
1090 inserts the __doc__ into the subclass instance __dict__.
1091
Antoine Pitrou244651a2009-05-04 18:56:13 +00001092- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1093 sequences. Patch by Nick Barnes and Victor Stinner.
1094
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001095- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001096
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001097- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1098 received a new method, detach(). detach() disconnects the underlying stream
1099 from the buffer or text IO and returns it.
1100
Mark Dickinson33841c32009-05-01 15:37:04 +00001101- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1102 floats with absolute value over 1e50. Also remove length
1103 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1104 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001105
Eric Smith741191f2009-05-06 13:08:15 +00001106- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001107 format(complex(1, 2./3), '.5') now produces a sensible result.
1108
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001109- Issue #5864: Fix empty format code formatting for floats so that it
1110 never gives more than the requested number of significant digits.
1111
Eric Smith6dc46f52009-04-27 20:39:49 +00001112- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1113 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1114
Eric Smithcc32a112009-04-26 21:35:14 +00001115- Issue #5835: Deprecate PyOS_ascii_formatd.
1116
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001117- Issue #4971: Fix titlecase for characters that are their own
1118 titlecase, but not their own uppercase.
1119
Benjamin Peterson193152c2009-04-25 01:08:45 +00001120- Issue #5283: Setting __class__ in __del__ caused a segfault.
1121
Mark Dickinsonad476da2009-04-23 19:14:16 +00001122- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1123 z involves nans, infs or negative zeros.
1124
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001125- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001126
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001127- Issue #1869 (and many duplicates): make round(x, n) correctly
1128 rounded for a float x, by using the decimal <-> binary conversions
1129 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1130 consistently agrees with format(x, '.2f').
1131
Benjamin Petersonae937c02009-04-18 20:54:08 +00001132- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1133 some builtin types.
1134
Eric Smith0923d1d2009-04-16 20:16:10 +00001135- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1136
Eric Smith35e84722009-04-16 20:21:28 +00001137- Issue #5515: str.format() type 'n' combined with commas and leading
1138 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001139
1140- Implement PEP 378, Format Specifier for Thousands Separator, for
1141 floats.
1142
Mark Dickinson3370cce2009-04-17 22:40:53 +00001143- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001144 1e11, not 1e12. This avoids printing 13 significant digits in
1145 situations where only 12 of them are correct. Example problem
1146 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1147 long time.)
1148
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001149- Issue #1580: On most platforms, use a 'short' float repr: for a
1150 finite float x, repr(x) now outputs a string based on the shortest
1151 sequence of decimal digits that rounds to x. Previous behaviour was
1152 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001153 Another minor difference is that the new repr switches to
1154 exponential notation at 1e16 instead of the previous 1e17; this
1155 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001156
1157 There's a new sys attribute sys.float_repr_style, which takes
1158 the value 'short' to indicate that we're using short float repr,
1159 and 'legacy' if the short float repr isn't available for one
1160 reason or another.
1161
1162 The float repr change involves incorporating David Gay's 'perfect
1163 rounding' code into the Python core (it's in Python/dtoa.c). As a
1164 secondary consequence, all string-to-float and float-to-string
1165 conversions (including all float formatting operations) will be
1166 correctly rounded on these platforms.
1167
1168 See issue 1580 discussions for details of platforms for which
1169 this change does not apply.
1170
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001171- Issue #5759: float() didn't call __float__ on str subclasses.
1172
Georg Brandlabc38772009-04-12 15:51:51 +00001173- The string.maketrans() function is deprecated; there is a new static method
1174 maketrans() on the bytes and bytearray classes. This removes confusion about
1175 the types string.maketrans() is supposed to work with, and mirrors the
1176 methods available on the str class.
1177
R. David Murraydc6da8a2009-04-09 22:16:43 +00001178- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1179 its clarity and its speed.
1180
Matthias Klose091c7b12009-04-07 13:24:27 +00001181- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001481- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001482 were suppressing all exceptions. These include list() and bytearray().
1483
Mark Dickinson1124e712009-01-28 21:25:58 +00001484- Issue #4707: round(x, n) now returns an integer if x is an integer.
1485 Previously it returned a float.
1486
Antoine Pitroub52ec782009-01-25 16:34:23 +00001487- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1488 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1489 evaluation loop is compiled with a new dispatch mechanism which gives
1490 speedups of up to 20%, depending on the system, on various benchmarks.
1491
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001492- Issue #4874: Most builtin decoders now reject unicode input.

1500 optional module state data.
1501
Mark Dickinson8055afd2009-01-17 10:04:45 +00001502- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1503 type to (void *).
1504
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001505- Issue #4935: The overflow checking code in the expandtabs() method common
1506 to str, bytes and bytearray could be optimized away by the compiler, letting
1507 the interpreter segfault instead of raising an error.
1508
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001509- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1510 __next__ method.
1511
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001512- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1513 function no longer attempt to call the __long__ slot to convert an object
1514 to an integer. Only the __int__ and __trunc__ slots are examined.

1519
Antoine Pitrouab868312009-01-10 15:40:25 +00001520- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1521 common cases are optimized thanks to a dedicated fast path and a moderate
1522 amount of loop unrolling.
1523
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001524- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1525 collecting the oldest generation) so that allocating lots of objects without
1526 destroying them does not show quadratic performance. Based on a proposal by
1527 Martin von Löwis at
1528 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1529
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001530- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001531 having been closed (for instance, a read() call could return some
1532 previously buffered data). Patch by Dmitry Vasiliev.
1533
Antoine Pitrou05608432009-01-09 18:53:14 +00001534- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1535 flag to work properly. Furthermore, when specifying -u, the text stdout
1536 and stderr streams have line-by-line buffering enabled (the default being
1537 to buffer arbitrary chunks of data).
1538
Raymond Hettinger35631532009-01-09 03:58:09 +00001539- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1540 instead of ints (reducing its size from 4 to 8 times thereby reducing
1541 Python's overall memory).
1542
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001543- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1544 an existing .py counterpart, override the co_filename attributes of all
1545 code objects if the original filename is obsolete (which can happen if the
1546 file has been renamed, moved, or if it is accessed through different paths).
1547 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1548
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001549- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1550 one byte. Also fixes the meaning of len() so that it returns the number of
1551 items, rather than the size in bytes.
1552
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001553- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1554
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001555- Issue #4747: When the terminal does not use utf-8, executing a script with
1556 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1557
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001558- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001559 file with `bytes' filename on Windows.

1562 did not get collected.
1563
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001564- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1565 where the tp_hash and tp_dict slots are both NULL.
1566
Georg Brandlccc47b62008-12-28 11:44:14 +00001567- Issue #4759: None is now allowed as the first argument of
1568 bytearray.translate(). It was always allowed for bytes.translate().
1569
Skip Montanaro80072cb2008-12-23 03:51:14 +00001570- Added test case to ensure attempts to read from a file opened for writing
1571 fail.
1572

1577
Antoine Pitrou621601a2008-12-17 23:18:19 +00001578- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1580 unreachable. Original patch by Neil Schemenauer.
1581
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001582- Issue #3439: Add a bit_length method to int.
1583
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001584- Issue #2173: When getting device encoding, check that return value of
1585 nl_langinfo is not the empty string. This was causing silent build
1586 failures on OS X.
1587
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001588- Issue #4597: Fixed several opcodes that weren't always propagating
1589 exceptions.
1590
1591- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001592 context manager returns a value that cannot be converted to a bool.
1593
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001594- Issue #4445: Replace "sizeof(PyBytesObject)" with
1595 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1596 bytes instances. On a typical machine this saves 3 bytes of memory
1597 (on average) per allocation of a bytes instance.
1598
Christian Heimesa872de52008-12-05 08:26:55 +00001599- Issue #4533: File read operation was dreadfully slow due to a slowly
1600 growing read buffer. Fixed by using the same growth rate algorithm as
1601 Python 2.x.
1602
Antoine Pitrou5504e892008-12-06 21:27:53 +00001603- Issue #4509: Various issues surrounding resize of bytearray objects to
1604 which there are buffer exports (e.g. memoryview instances).
1605
Georg Brandlf9734072008-12-07 15:30:06 +00001606- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1607 method on file objects with closefd=False. The file descriptor is still
1608 kept open but the file object behaves like a closed file. The ``FileIO``
1609 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001618- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1619 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1620 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1621 of using the replace error handler in PyUnicode_DecodeUTF8().
