888Core and Builtins
889-----------------
890
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000891- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
892 of the command line.
893
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000894- Issue #6012: Add cleanup support to O& argument parsing.
895
Eric Smith41669ca2009-05-23 14:23:22 +0000896- Issue #6089: Fixed str.format with certain invalid field specifiers
897 that would raise SystemError.
898
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000899- Issue #5982: staticmethod and classmethod now expose the wrapped
900 function with __func__.
901
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000902- Added support for multiple context managers in the same with-statement.
903 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000904
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000905- Issue #5829: complex("1e500") no longer raises OverflowError. This
906 makes it consistent with float("1e500") and interpretation of real
907 and imaginary literals.
908
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000909- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
910
R. David Murraydd226ea2009-05-13 12:27:21 +0000911- Issue #5994: the marshal module now has docstrings.
912
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000913- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
914 (1) inf and nan strings with trailing whitespace were incorrectly
915 rejected; (2) parsing of strings representing infinities and nans
916 was locale aware; and (3) the interpretation of fromhex('-nan')
917 didn't match that of float('-nan').

920-------
921
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000922- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
923
R. David Murrayfb123912009-05-28 18:19:00 +0000924- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
925
R. David Murray1f1b9d32009-05-27 20:56:59 +0000926- Issue #6121: pydoc now ignores leading and trailing spaces in the
927 argument to the 'help' function.
928
Georg Brandlfaf41492009-05-26 18:31:11 +0000929- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
930 arguments for strings with a space in them.
931
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000932- collections.namedtuple() was not working with the following field
933 names: cls, self, tuple, itemgetter, and property.
934
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000935- In unittest, using a skipping decorator on a class is now equivalent to
936 skipping every test on the class. The ClassTestSuite class has been removed.
937
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000938- Issue #6050: Don't fail extracting a directory from a zipfile if
939 the directory already exists.
940
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000941- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
942 than an int, which makes some operations possible under 64-bit Linux (e.g.
943 DN_MULTISHOT with F_NOTIFY).
944
Antoine Pitrou716c4442009-05-23 19:04:03 +0000945- Issue #5761: Add the name of the underlying file to the repr() of various
946 IO objects.
947
R. David Murraycaa27b72009-05-23 18:49:56 +0000948- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
949 by Musashi Tamura, tests by Marcin Bachry.
950
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000951- Issue #1983: Fix functions taking or returning a process identifier to use
952 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
953 a process identifier type wider than the standard C integer type.
954
R. David Murray87e20742009-05-23 01:30:26 +0000955- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
956 Patch by Farhan Ahmad, test by Marcin Bachry.
957
Antoine Pitrou6e610062009-05-15 17:04:50 +0000958- Issue #2116: Weak references and weak dictionaries now support copy()ing and
959 deepcopy()ing.
960

962
Antoine Pitrou37d1c182009-05-14 21:54:00 +0000963- Issue #5918: Fix a crash in the parser module.
964
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000965- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
966
Antoine Pitroue4501852009-05-14 18:55:55 +0000967- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
968 library. This means, for example, that opening an UTF-16 text file in
969 append mode doesn't add a BOM at the end of the file if the file isn't
970 empty.
971
R. David Murray74b89242009-05-13 17:33:03 +0000972- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
973 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
974 corrects a pydoc regression.
975
R. David Murray99352742009-05-07 18:24:38 +0000976- Issue 5955: aifc's close method did not close the file it wrapped,
977 now it does. This also means getfp method now returns the real fp.
978
Benjamin Peterson932073a2009-05-23 16:14:33 +0000979Installation
980------------
981
982- Issue #6047: fullinstall has been removed because Python 3's executable will
983 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +0000984
Ronald Oussorenbe7149e2009-05-26 21:39:08 +0000985- Lib/smtpd.py is no longer installed as a script.

Brett Cannon1262e7c2009-05-11 01:47:11 +00001006Tests
1007-----
1008
1009- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1010 tests on darwin even when the OS was installed on a case-sensitive

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001015What's New in Python 3.1 beta 1?
1016================================
1017
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001018*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001019
1020Core and Builtins
1021-----------------
1022
Mark Dickinson865e01a2009-05-07 16:37:01 +00001023- Issue #5914: Add new C API function PyOS_string_to_double, and
1024 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1025
Eric Smith741191f2009-05-06 13:08:15 +00001026- Issue #3382: float.__format__, complex.__format__, and %-formatting
1027 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1028 affects nan -> NAN and inf -> INF.
1029
Mark Hammond5a607a32009-05-06 08:04:54 +00001030- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1031 in all operations, including splitdrive, split, etc. splitunc() now issues
1032 a PendingDeprecation warning.
1033
Eric Smith63376222009-05-05 14:04:18 +00001034- Issue #5920: For float.__format__, change the behavior with the
1035 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1036 to be like 'g' but with at least one decimal point and with a
1037 default precision of 12. Previously, the behavior the same but with
1038 a default precision of 6. This more closely matches str(), and
1039 reduces surprises when adding alignment flags to the empty
1040 presentation type. This also affects the new complex.__format__ in
1041 the same way.
1042
Martin v. Löwis011e8422009-05-05 04:43:17 +00001043- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1044
R. David Murrayb18500d2009-05-04 22:59:07 +00001045- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1046 shadowed by classtype's, even if it was None. property now
1047 inserts the __doc__ into the subclass instance __dict__.
1048
Antoine Pitrou244651a2009-05-04 18:56:13 +00001049- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1050 sequences. Patch by Nick Barnes and Victor Stinner.
1051
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001052- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001053
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001054- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1055 received a new method, detach(). detach() disconnects the underlying stream
1056 from the buffer or text IO and returns it.
1057
Mark Dickinson33841c32009-05-01 15:37:04 +00001058- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1059 floats with absolute value over 1e50. Also remove length
1060 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1061 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001062
Eric Smith741191f2009-05-06 13:08:15 +00001063- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001064 format(complex(1, 2./3), '.5') now produces a sensible result.
1065
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001066- Issue #5864: Fix empty format code formatting for floats so that it
1067 never gives more than the requested number of significant digits.
1068
Eric Smith6dc46f52009-04-27 20:39:49 +00001069- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1070 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1071
Eric Smithcc32a112009-04-26 21:35:14 +00001072- Issue #5835: Deprecate PyOS_ascii_formatd.
1073
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001074- Issue #4971: Fix titlecase for characters that are their own
1075 titlecase, but not their own uppercase.
1076
Benjamin Peterson193152c2009-04-25 01:08:45 +00001077- Issue #5283: Setting __class__ in __del__ caused a segfault.
1078
Mark Dickinsonad476da2009-04-23 19:14:16 +00001079- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1080 z involves nans, infs or negative zeros.
1081
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001082- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001083
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001084- Issue #1869 (and many duplicates): make round(x, n) correctly
1085 rounded for a float x, by using the decimal <-> binary conversions
1086 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1087 consistently agrees with format(x, '.2f').
1088
Benjamin Petersonae937c02009-04-18 20:54:08 +00001089- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1090 some builtin types.
1091
Eric Smith0923d1d2009-04-16 20:16:10 +00001092- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1093
Eric Smith35e84722009-04-16 20:21:28 +00001094- Issue #5515: str.format() type 'n' combined with commas and leading
1095 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001096
1097- Implement PEP 378, Format Specifier for Thousands Separator, for
1098 floats.
1099
Mark Dickinson3370cce2009-04-17 22:40:53 +00001100- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001101 1e11, not 1e12. This avoids printing 13 significant digits in
1102 situations where only 12 of them are correct. Example problem
1103 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1104 long time.)
1105
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001106- Issue #1580: On most platforms, use a 'short' float repr: for a
1107 finite float x, repr(x) now outputs a string based on the shortest
1108 sequence of decimal digits that rounds to x. Previous behaviour was
1109 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001110 Another minor difference is that the new repr switches to
1111 exponential notation at 1e16 instead of the previous 1e17; this
1112 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001113
1114 There's a new sys attribute sys.float_repr_style, which takes
1115 the value 'short' to indicate that we're using short float repr,
1116 and 'legacy' if the short float repr isn't available for one
1117 reason or another.
1118
1119 The float repr change involves incorporating David Gay's 'perfect
1120 rounding' code into the Python core (it's in Python/dtoa.c). As a
1121 secondary consequence, all string-to-float and float-to-string
1122 conversions (including all float formatting operations) will be
1123 correctly rounded on these platforms.
1124
1125 See issue 1580 discussions for details of platforms for which
1126 this change does not apply.
1127
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001128- Issue #5759: float() didn't call __float__ on str subclasses.
1129
Georg Brandlabc38772009-04-12 15:51:51 +00001130- The string.maketrans() function is deprecated; there is a new static method
1131 maketrans() on the bytes and bytearray classes. This removes confusion about
1132 the types string.maketrans() is supposed to work with, and mirrors the
1133 methods available on the str class.
1134
R. David Murraydc6da8a2009-04-09 22:16:43 +00001135- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1136 its clarity and its speed.
1137
Matthias Klose091c7b12009-04-07 13:24:27 +00001138- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1139 to avoid compiler warnings.
1140
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001141- Issue #3739: The unicode-internal encoder now reports the number of characters
1142 consumed like any other encoder (instead of the number of bytes).

1157
Vinay Sajipaffbd872009-06-11 10:11:47 +00001158- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1179 and original patch by Jake McGuire.
1180

Martin v. Löwisec59d042009-01-12 07:59:10 +00001475- Issue #4915: Port sysmodule to Windows CE.
1476
Antoine Pitrouab868312009-01-10 15:40:25 +00001477- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1478 common cases are optimized thanks to a dedicated fast path and a moderate
1479 amount of loop unrolling.
1480
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001481- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1482 collecting the oldest generation) so that allocating lots of objects without
1483 destroying them does not show quadratic performance. Based on a proposal by
1484 Martin von Löwis at
1485 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1486
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001487- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001488 having been closed (for instance, a read() call could return some
1489 previously buffered data). Patch by Dmitry Vasiliev.
1490
Antoine Pitrou05608432009-01-09 18:53:14 +00001491- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1492 flag to work properly. Furthermore, when specifying -u, the text stdout
1493 and stderr streams have line-by-line buffering enabled (the default being
1494 to buffer arbitrary chunks of data).
1495
Raymond Hettinger35631532009-01-09 03:58:09 +00001496- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1497 instead of ints (reducing its size from 4 to 8 times thereby reducing
1498 Python's overall memory).
1499
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001500- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1501 an existing .py counterpart, override the co_filename attributes of all
1502 code objects if the original filename is obsolete (which can happen if the
1503 file has been renamed, moved, or if it is accessed through different paths).
1504 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1505
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001506- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1507 one byte. Also fixes the meaning of len() so that it returns the number of
1508 items, rather than the size in bytes.
1509
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001510- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1511
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001512- Issue #4747: When the terminal does not use utf-8, executing a script with
1513 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1514
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001515- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001516 file with `bytes' filename on Windows.

1519 did not get collected.
1520
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001521- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1522 where the tp_hash and tp_dict slots are both NULL.
1523
Georg Brandlccc47b62008-12-28 11:44:14 +00001524- Issue #4759: None is now allowed as the first argument of
1525 bytearray.translate(). It was always allowed for bytes.translate().
1526
Skip Montanaro80072cb2008-12-23 03:51:14 +00001527- Added test case to ensure attempts to read from a file opened for writing
1528 fail.

1534
Antoine Pitrou621601a2008-12-17 23:18:19 +00001535- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1537 unreachable. Original patch by Neil Schemenauer.
1538
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001539- Issue #3439: Add a bit_length method to int.
1540
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001541- Issue #2173: When getting device encoding, check that return value of
1542 nl_langinfo is not the empty string. This was causing silent build
1543 failures on OS X.
1544
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001545- Issue #4597: Fixed several opcodes that weren't always propagating
1546 exceptions.
1547
1548- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001549 context manager returns a value that cannot be converted to a bool.
1550
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001551- Issue #4445: Replace "sizeof(PyBytesObject)" with
1552 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1553 bytes instances. On a typical machine this saves 3 bytes of memory
1554 (on average) per allocation of a bytes instance.
1555
Christian Heimesa872de52008-12-05 08:26:55 +00001556- Issue #4533: File read operation was dreadfully slow due to a slowly
1557 growing read buffer. Fixed by using the same growth rate algorithm as
1558 Python 2.x.
1559
Antoine Pitrou5504e892008-12-06 21:27:53 +00001560- Issue #4509: Various issues surrounding resize of bytearray objects to
1561 which there are buffer exports (e.g. memoryview instances).
1562
Georg Brandlf9734072008-12-07 15:30:06 +00001563- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1564 method on file objects with closefd=False. The file descriptor is still
1565 kept open but the file object behaves like a closed file. The ``FileIO``
1566 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001567
Antoine Pitroubc420402008-12-07 20:14:49 +00001568- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1574
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001575- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1576 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1577 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1578 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00001856- Issue #5008: When a file is opened in append mode with the new IO library,
1857 do an explicit seek to the end of file (so that e.g. tell() returns the
