Antoine Pitroue4501852009-05-14 18:55:55 +0000632- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
633 library. This means, for example, that opening an UTF-16 text file in
634 append mode doesn't add a BOM at the end of the file if the file isn't
635 empty.
636
R. David Murray74b89242009-05-13 17:33:03 +0000637- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

639 corrects a pydoc regression.
640
R. David Murray99352742009-05-07 18:24:38 +0000641- Issue 5955: aifc's close method did not close the file it wrapped,

685Core and Builtins
686-----------------
687
Mark Dickinson865e01a2009-05-07 16:37:01 +0000688- Issue #5914: Add new C API function PyOS_string_to_double, and
689 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
690
Eric Smith741191f2009-05-06 13:08:15 +0000691- Issue #3382: float.__format__, complex.__format__, and %-formatting
692 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
693 affects nan -> NAN and inf -> INF.
694
Mark Hammond5a607a32009-05-06 08:04:54 +0000695- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
696 in all operations, including splitdrive, split, etc. splitunc() now issues
697 a PendingDeprecation warning.
698
Eric Smith63376222009-05-05 14:04:18 +0000699- Issue #5920: For float.__format__, change the behavior with the
700 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
701 to be like 'g' but with at least one decimal point and with a
702 default precision of 12. Previously, the behavior the same but with
703 a default precision of 6. This more closely matches str(), and
704 reduces surprises when adding alignment flags to the empty
705 presentation type. This also affects the new complex.__format__ in
706 the same way.
707
Martin v. Löwis011e8422009-05-05 04:43:17 +0000708- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
709
R. David Murrayb18500d2009-05-04 22:59:07 +0000710- Issue #5890: in subclasses of 'property' the __doc__ attribute was
711 shadowed by classtype's, even if it was None. property now
712 inserts the __doc__ into the subclass instance __dict__.
713
Antoine Pitrou244651a2009-05-04 18:56:13 +0000714- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
715 sequences. Patch by Nick Barnes and Victor Stinner.
716
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000717- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000718
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000719- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
720 received a new method, detach(). detach() disconnects the underlying stream
721 from the buffer or text IO and returns it.
722
Mark Dickinson33841c32009-05-01 15:37:04 +0000723- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
724 floats with absolute value over 1e50. Also remove length
725 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
726 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000727
Eric Smith741191f2009-05-06 13:08:15 +0000728- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000729 format(complex(1, 2./3), '.5') now produces a sensible result.
730
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000731- Issue #5864: Fix empty format code formatting for floats so that it
732 never gives more than the requested number of significant digits.
733
Eric Smith6dc46f52009-04-27 20:39:49 +0000734- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
735 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
736
Eric Smithcc32a112009-04-26 21:35:14 +0000737- Issue #5835: Deprecate PyOS_ascii_formatd.
738
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000739- Issue #4971: Fix titlecase for characters that are their own
740 titlecase, but not their own uppercase.
741
Benjamin Peterson193152c2009-04-25 01:08:45 +0000742- Issue #5283: Setting __class__ in __del__ caused a segfault.
743
Mark Dickinsonad476da2009-04-23 19:14:16 +0000744- Issue #5816: complex(repr(z)) now recovers z exactly, even when
745 z involves nans, infs or negative zeros.
746
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000747- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000748
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000749- Issue #1869 (and many duplicates): make round(x, n) correctly
750 rounded for a float x, by using the decimal <-> binary conversions
751 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
752 consistently agrees with format(x, '.2f').
753
Benjamin Petersonae937c02009-04-18 20:54:08 +0000754- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
755 some builtin types.
756
Eric Smith0923d1d2009-04-16 20:16:10 +0000757- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
758
Eric Smith35e84722009-04-16 20:21:28 +0000759- Issue #5515: str.format() type 'n' combined with commas and leading
760 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000761
762- Implement PEP 378, Format Specifier for Thousands Separator, for
763 floats.
764
Mark Dickinson3370cce2009-04-17 22:40:53 +0000765- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000766 1e11, not 1e12. This avoids printing 13 significant digits in
767 situations where only 12 of them are correct. Example problem
768 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
769 long time.)
770
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000771- Issue #1580: On most platforms, use a 'short' float repr: for a
772 finite float x, repr(x) now outputs a string based on the shortest
773 sequence of decimal digits that rounds to x. Previous behaviour was
774 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000775 Another minor difference is that the new repr switches to
776 exponential notation at 1e16 instead of the previous 1e17; this
777 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000778
779 There's a new sys attribute sys.float_repr_style, which takes
780 the value 'short' to indicate that we're using short float repr,
781 and 'legacy' if the short float repr isn't available for one
782 reason or another.
783
784 The float repr change involves incorporating David Gay's 'perfect
785 rounding' code into the Python core (it's in Python/dtoa.c). As a
786 secondary consequence, all string-to-float and float-to-string
787 conversions (including all float formatting operations) will be
788 correctly rounded on these platforms.
789
790 See issue 1580 discussions for details of platforms for which
791 this change does not apply.
792
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000793- Issue #5759: float() didn't call __float__ on str subclasses.
794
Georg Brandlabc38772009-04-12 15:51:51 +0000795- The string.maketrans() function is deprecated; there is a new static method
796 maketrans() on the bytes and bytearray classes. This removes confusion about
797 the types string.maketrans() is supposed to work with, and mirrors the
798 methods available on the str class.
799
R. David Murraydc6da8a2009-04-09 22:16:43 +0000800- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
801 its clarity and its speed.
802
Matthias Klose091c7b12009-04-07 13:24:27 +0000803- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
804 to avoid compiler warnings.
805
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000806- Issue #3739: The unicode-internal encoder now reports the number of characters
807 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000942- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
943
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000944- Issue #5499: The 'c' code for argument parsing functions now only accepts a
945 byte, and the 'C' code only accepts a unicode character.
946
Georg Brandl406b3d82009-04-11 21:24:37 +0000947- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
948 when hitting the recursion limit under certain circumstances.
949
Brett Cannon0759dd62009-04-01 18:13:07 +0000950- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
951
Georg Brandlab6f2f62009-03-31 04:16:10 +0000952- Fix a segfault when running test_exceptions with coverage, caused by
953 insufficient checks in accessors of Exception.__context__.
954
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000955- Issue #5604: non-ASCII characters in module name passed to
956 imp.find_module() were converted to UTF-8 while the path is
957 converted to the default filesystem encoding, causing nonsense.
958
Benjamin Peterson09832742009-03-26 17:15:46 +0000959- Issue #5126: str.isprintable() returned False for space characters.
960
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +0000961- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
962 the end sys.path, for compatibility with the system install of Python.
963
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000964- Issue #4688: Add a heuristic so that tuples and dicts containing only
965 untrackable objects are not tracked by the garbage collector. This can
966 reduce the size of collections and therefore the garbage collection overhead
967 on long-running programs, depending on their particular use of datatypes.
968
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000969- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

977 default. Add sys.int_info structseq to provide information about
978 the internal format.
979
Mark Dickinson081dfee2009-03-18 14:47:41 +0000980- Issue #4474: PyUnicode_FromWideChar now converts characters outside
981 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
982 and sizeof(Py_UNICODE) == 2.
983
Eric Smith8ec90442009-03-14 12:29:34 +0000984- Issue #5237: Allow auto-numbered fields in str.format(). For
985 example: '{} {}'.format(1, 2) == '1 2'.
986
Antoine Pitrou652e7072009-03-13 19:25:20 +0000987- Issue #5392: when a very low recursion limit was set, the interpreter would
988 abort with a fatal error after the recursion limit was hit twice.
989
Matthias Klose042f1332009-04-04 14:32:42 +0000990- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1000 error substitutions from non-strict codec error callbacks in
1001 incrementalencoder and StreamWriter.
1002
Georg Brandl33c28812009-04-01 23:07:29 +00001003- Issue #5656: Fix the coverage reporting when running the test suite with

1021
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001022- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1023 bytes already but the failure was non-obvious.
1024
Jesse Noller7af4ef82009-03-30 16:47:15 +00001025- Issue #5177: Multiprocessing's SocketListener class now uses

1032 (typically /dev/zero under Unix) could crash the interpreter.
1033
Benjamin Peterson59406a92009-03-26 17:10:29 +00001034- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1036
Lars Gustäbel42e00912009-03-22 20:34:29 +00001037- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1038 forever on incomplete input. That caused tarfile.open() to hang when used
1039 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1040 partial bzip2 compressed data.
1041
Mark Dickinson79f52032009-03-17 23:12:51 +00001042- Issue #2110: Add support for thousands separator and 'n' type

1047
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001048- The error detection code in FileIO.close() could fail to reflect the `errno`
1049 value, and report it as -1 instead.

1060 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001061 struct.error instead of returning b'\xff\xff\xff\xff'. The
1062 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1063 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001090- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1091 it now forces its argument to double before testing for infinity.
1092
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001093- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001102
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001103- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001104 were suppressing all exceptions. These include list() and bytearray().

1110 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1111 evaluation loop is compiled with a new dispatch mechanism which gives
1112 speedups of up to 20%, depending on the system, on various benchmarks.

1125 type to (void *).
1126
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001127- Issue #4935: The overflow checking code in the expandtabs() method common
1128 to str, bytes and bytearray could be optimized away by the compiler, letting
1129 the interpreter segfault instead of raising an error.
1130
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001131- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1150 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1151

1154 previously buffered data). Patch by Dmitry Vasiliev.
1155
Antoine Pitrou05608432009-01-09 18:53:14 +00001156- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1157 flag to work properly. Furthermore, when specifying -u, the text stdout
1158 and stderr streams have line-by-line buffering enabled (the default being
1159 to buffer arbitrary chunks of data).
1160
Raymond Hettinger35631532009-01-09 03:58:09 +00001161- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1162 instead of ints (reducing its size from 4 to 8 times thereby reducing
1163 Python's overall memory).
1164
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001165- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1166 an existing .py counterpart, override the co_filename attributes of all
1167 code objects if the original filename is obsolete (which can happen if the
1168 file has been renamed, moved, or if it is accessed through different paths).
1169 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1170
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001171- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1172 one byte. Also fixes the meaning of len() so that it returns the number of
1173 items, rather than the size in bytes.
1174
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001175- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1176
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001177- Issue #4747: When the terminal does not use utf-8, executing a script with

1188
Georg Brandlccc47b62008-12-28 11:44:14 +00001189- Issue #4759: None is now allowed as the first argument of

1241 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1242 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1243 of using the replace error handler in PyUnicode_DecodeUTF8().

1564 do an explicit seek to the end of file (so that e.g. tell() returns the

1849 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1850 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1851 skip the tests if DISPLAY is defined but can't be used.
1852
R. David Murraya21e4ca2009-03-31 23:16:50 +00001853- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001854 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001855 from test support, which does the conversion.
1856
Guilherme Polo9de29af2009-01-28 20:40:48 +00001857- Issue #5083: New 'gui' resource for regrtest.
