879 didn't match that of float('-nan').

982Core and Builtins
983-----------------
984
Mark Dickinson865e01a2009-05-07 16:37:01 +0000985- Issue #5914: Add new C API function PyOS_string_to_double, and
986 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
987
Eric Smith741191f2009-05-06 13:08:15 +0000988- Issue #3382: float.__format__, complex.__format__, and %-formatting
989 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
990 affects nan -> NAN and inf -> INF.
991
Mark Hammond5a607a32009-05-06 08:04:54 +0000992- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
993 in all operations, including splitdrive, split, etc. splitunc() now issues
994 a PendingDeprecation warning.
995
Eric Smith63376222009-05-05 14:04:18 +0000996- Issue #5920: For float.__format__, change the behavior with the
997 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
998 to be like 'g' but with at least one decimal point and with a
999 default precision of 12. Previously, the behavior the same but with
1000 a default precision of 6. This more closely matches str(), and
1001 reduces surprises when adding alignment flags to the empty
1002 presentation type. This also affects the new complex.__format__ in
1003 the same way.
1004
Martin v. Löwis011e8422009-05-05 04:43:17 +00001005- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1006
R. David Murrayb18500d2009-05-04 22:59:07 +00001007- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1008 shadowed by classtype's, even if it was None. property now
1009 inserts the __doc__ into the subclass instance __dict__.
1010
Antoine Pitrou244651a2009-05-04 18:56:13 +00001011- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1012 sequences. Patch by Nick Barnes and Victor Stinner.
1013
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001014- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001015
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001016- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1017 received a new method, detach(). detach() disconnects the underlying stream
1018 from the buffer or text IO and returns it.
1019
Mark Dickinson33841c32009-05-01 15:37:04 +00001020- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1021 floats with absolute value over 1e50. Also remove length
1022 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1023 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001024
Eric Smith741191f2009-05-06 13:08:15 +00001025- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001026 format(complex(1, 2./3), '.5') now produces a sensible result.
1027
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001028- Issue #5864: Fix empty format code formatting for floats so that it
1029 never gives more than the requested number of significant digits.
1030
Eric Smith6dc46f52009-04-27 20:39:49 +00001031- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1032 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1033
Eric Smithcc32a112009-04-26 21:35:14 +00001034- Issue #5835: Deprecate PyOS_ascii_formatd.
1035
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001036- Issue #4971: Fix titlecase for characters that are their own
1037 titlecase, but not their own uppercase.
1038
Benjamin Peterson193152c2009-04-25 01:08:45 +00001039- Issue #5283: Setting __class__ in __del__ caused a segfault.
1040
Mark Dickinsonad476da2009-04-23 19:14:16 +00001041- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1042 z involves nans, infs or negative zeros.
1043
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001044- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001045
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001046- Issue #1869 (and many duplicates): make round(x, n) correctly
1047 rounded for a float x, by using the decimal <-> binary conversions
1048 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1049 consistently agrees with format(x, '.2f').
1050
Benjamin Petersonae937c02009-04-18 20:54:08 +00001051- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1052 some builtin types.
1053
Eric Smith0923d1d2009-04-16 20:16:10 +00001054- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1055
Eric Smith35e84722009-04-16 20:21:28 +00001056- Issue #5515: str.format() type 'n' combined with commas and leading
1057 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001058
1059- Implement PEP 378, Format Specifier for Thousands Separator, for
1060 floats.
1061
Mark Dickinson3370cce2009-04-17 22:40:53 +00001062- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001063 1e11, not 1e12. This avoids printing 13 significant digits in
1064 situations where only 12 of them are correct. Example problem
1065 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1066 long time.)
1067
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001068- Issue #1580: On most platforms, use a 'short' float repr: for a
1069 finite float x, repr(x) now outputs a string based on the shortest
1070 sequence of decimal digits that rounds to x. Previous behaviour was
1071 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001072 Another minor difference is that the new repr switches to
1073 exponential notation at 1e16 instead of the previous 1e17; this
1074 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001075
1076 There's a new sys attribute sys.float_repr_style, which takes
1077 the value 'short' to indicate that we're using short float repr,
1078 and 'legacy' if the short float repr isn't available for one
1079 reason or another.
1080
1081 The float repr change involves incorporating David Gay's 'perfect
1082 rounding' code into the Python core (it's in Python/dtoa.c). As a
1083 secondary consequence, all string-to-float and float-to-string
1084 conversions (including all float formatting operations) will be
1085 correctly rounded on these platforms.
1086
1087 See issue 1580 discussions for details of platforms for which
1088 this change does not apply.
1089
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001090- Issue #5759: float() didn't call __float__ on str subclasses.
1091
Georg Brandlabc38772009-04-12 15:51:51 +00001092- The string.maketrans() function is deprecated; there is a new static method
1093 maketrans() on the bytes and bytearray classes. This removes confusion about
1094 the types string.maketrans() is supposed to work with, and mirrors the
1095 methods available on the str class.
1096
R. David Murraydc6da8a2009-04-09 22:16:43 +00001097- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1098 its clarity and its speed.
1099
Matthias Klose091c7b12009-04-07 13:24:27 +00001100- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1101 to avoid compiler warnings.
1102
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001103- Issue #3739: The unicode-internal encoder now reports the number of characters
1104 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00001182- Issue #1161031: fix readwrite select flag handling: POLLPRI now
1183 results in a handle_expt_event call, not handle_read_event, and POLLERR
1184 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1185 dispatcher now has an 'ignore_log_types' attribute for suppressing
1186 log messages, which is set to 'warning' by default.
1187
Matthias Klosea3d29e82009-04-07 13:13:10 +00001188- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
1189 new arguments introduced in 2.5.

1211
1212- Issue #5354: New test support function import_fresh_module() makes
1213 it easy to import both normal and optimised versions of modules.
1214 test_heapq and test_warnings have been adjusted to use it, tests for
1215 other modules with both C and Python implementations in the stdlib
1216 can be adjusted to use it over time.
1217
Walter Dörwald4ba80132009-04-25 12:48:43 +00001218- Issue #5837: Certain sequences of calls to set() and unset() for
1219 support.EnvironmentVarGuard objects restored the environment variables
1220 incorrectly on __exit__.

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001239- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1240
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001241- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1242 byte, and the 'C' code only accepts a unicode character.
1243
Georg Brandl406b3d82009-04-11 21:24:37 +00001244- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1245 when hitting the recursion limit under certain circumstances.
1246
Brett Cannon0759dd62009-04-01 18:13:07 +00001247- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1248
Georg Brandlab6f2f62009-03-31 04:16:10 +00001249- Fix a segfault when running test_exceptions with coverage, caused by
1250 insufficient checks in accessors of Exception.__context__.
1251
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001252- Issue #5604: non-ASCII characters in module name passed to
1253 imp.find_module() were converted to UTF-8 while the path is
1254 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001256- Issue #5126: str.isprintable() returned False for space characters.
1257
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001258- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1259 the end sys.path, for compatibility with the system install of Python.
1260
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001261- Issue #4688: Add a heuristic so that tuples and dicts containing only
1262 untrackable objects are not tracked by the garbage collector. This can
1263 reduce the size of collections and therefore the garbage collection overhead
1264 on long-running programs, depending on their particular use of datatypes.
1265
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001266- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1271 2**15 for the internal representation of integers, for performance
1272 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1273 --enable-big-digits option to configure, which overrides the
1274 default. Add sys.int_info structseq to provide information about
1275 the internal format.
1276
Mark Dickinson081dfee2009-03-18 14:47:41 +00001277- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1278 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1279 and sizeof(Py_UNICODE) == 2.
1280
Eric Smith8ec90442009-03-14 12:29:34 +00001281- Issue #5237: Allow auto-numbered fields in str.format(). For

1283
Antoine Pitrou652e7072009-03-13 19:25:20 +00001284- Issue #5392: when a very low recursion limit was set, the interpreter would
1285 abort with a fatal error after the recursion limit was hit twice.
1286
Matthias Klose042f1332009-04-04 14:32:42 +00001287- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1288 short file names.

1333
Lars Gustäbel42e00912009-03-22 20:34:29 +00001334- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1335 forever on incomplete input. That caused tarfile.open() to hang when used
1336 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1337 partial bzip2 compressed data.
1338
Mark Dickinson79f52032009-03-17 23:12:51 +00001339- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001358 struct.error instead of returning b'\xff\xff\xff\xff'. The
1359 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1360 have been removed from the struct module.

1442
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001443- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1444 collecting the oldest generation) so that allocating lots of objects without
1445 destroying them does not show quadratic performance. Based on a proposal by
1446 Martin von Löwis at
1447 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1448
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001449- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001450 having been closed (for instance, a read() call could return some
1451 previously buffered data). Patch by Dmitry Vasiliev.
1452
Antoine Pitrou05608432009-01-09 18:53:14 +00001453- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1454 flag to work properly. Furthermore, when specifying -u, the text stdout
1455 and stderr streams have line-by-line buffering enabled (the default being
1456 to buffer arbitrary chunks of data).
1457
Raymond Hettinger35631532009-01-09 03:58:09 +00001458- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1459 instead of ints (reducing its size from 4 to 8 times thereby reducing
1460 Python's overall memory).
1461
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001462- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1463 an existing .py counterpart, override the co_filename attributes of all
1464 code objects if the original filename is obsolete (which can happen if the
1465 file has been renamed, moved, or if it is accessed through different paths).
1466 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1467
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001468- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1469 one byte. Also fixes the meaning of len() so that it returns the number of
1470 items, rather than the size in bytes.
1471

1819 do an explicit seek to the end of file (so that e.g. tell() returns the

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002097- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2098 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2099 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2100 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002103 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002104 from test support, which does the conversion.
