155 to execute file paths that refer to source or compiled Python files as well
156 as zipfiles, directories and other valid sys.path entries that contain a

189 failures on systems with slightly bogus mtime behaviour.
190
Gregory P. Smith50467882009-11-01 18:42:17 +0000191- Issue #7246 & Issue #7208: getpass now properly flushes input before
192 reading from stdin so that existing input does not confuse it and
193 lead to incorrect entry or an IOError. It also properly flushes it
194 afterwards to avoid the terminal echoing the input afterwards on
195 OSes such as Solaris.
196
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000197- Issue #7233: Fix a number of two-argument Decimal methods to make

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

725Core and Builtins
726-----------------
727
Mark Dickinson865e01a2009-05-07 16:37:01 +0000728- Issue #5914: Add new C API function PyOS_string_to_double, and
729 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
730
Eric Smith741191f2009-05-06 13:08:15 +0000731- Issue #3382: float.__format__, complex.__format__, and %-formatting
732 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
733 affects nan -> NAN and inf -> INF.
734
Mark Hammond5a607a32009-05-06 08:04:54 +0000735- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
736 in all operations, including splitdrive, split, etc. splitunc() now issues
737 a PendingDeprecation warning.
738
Eric Smith63376222009-05-05 14:04:18 +0000739- Issue #5920: For float.__format__, change the behavior with the
740 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
741 to be like 'g' but with at least one decimal point and with a
742 default precision of 12. Previously, the behavior the same but with
743 a default precision of 6. This more closely matches str(), and
744 reduces surprises when adding alignment flags to the empty
745 presentation type. This also affects the new complex.__format__ in
746 the same way.
747
Martin v. Löwis011e8422009-05-05 04:43:17 +0000748- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
749
R. David Murrayb18500d2009-05-04 22:59:07 +0000750- Issue #5890: in subclasses of 'property' the __doc__ attribute was
751 shadowed by classtype's, even if it was None. property now
752 inserts the __doc__ into the subclass instance __dict__.
753
Antoine Pitrou244651a2009-05-04 18:56:13 +0000754- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
755 sequences. Patch by Nick Barnes and Victor Stinner.
756
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000757- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000758
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000759- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
760 received a new method, detach(). detach() disconnects the underlying stream
761 from the buffer or text IO and returns it.
762
Mark Dickinson33841c32009-05-01 15:37:04 +0000763- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
764 floats with absolute value over 1e50. Also remove length
765 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
766 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000767
Eric Smith741191f2009-05-06 13:08:15 +0000768- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000769 format(complex(1, 2./3), '.5') now produces a sensible result.
770
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000771- Issue #5864: Fix empty format code formatting for floats so that it
772 never gives more than the requested number of significant digits.
773
Eric Smith6dc46f52009-04-27 20:39:49 +0000774- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
775 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
776
Eric Smithcc32a112009-04-26 21:35:14 +0000777- Issue #5835: Deprecate PyOS_ascii_formatd.
778
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000779- Issue #4971: Fix titlecase for characters that are their own
780 titlecase, but not their own uppercase.
781
Benjamin Peterson193152c2009-04-25 01:08:45 +0000782- Issue #5283: Setting __class__ in __del__ caused a segfault.
783
Mark Dickinsonad476da2009-04-23 19:14:16 +0000784- Issue #5816: complex(repr(z)) now recovers z exactly, even when
785 z involves nans, infs or negative zeros.
786
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000787- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000788
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000789- Issue #1869 (and many duplicates): make round(x, n) correctly
790 rounded for a float x, by using the decimal <-> binary conversions
791 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
792 consistently agrees with format(x, '.2f').
793
Benjamin Petersonae937c02009-04-18 20:54:08 +0000794- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
795 some builtin types.
796
Eric Smith0923d1d2009-04-16 20:16:10 +0000797- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
798
Eric Smith35e84722009-04-16 20:21:28 +0000799- Issue #5515: str.format() type 'n' combined with commas and leading
800 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000801
802- Implement PEP 378, Format Specifier for Thousands Separator, for
803 floats.
804
Mark Dickinson3370cce2009-04-17 22:40:53 +0000805- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000806 1e11, not 1e12. This avoids printing 13 significant digits in
807 situations where only 12 of them are correct. Example problem
808 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
809 long time.)
810
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000811- Issue #1580: On most platforms, use a 'short' float repr: for a
812 finite float x, repr(x) now outputs a string based on the shortest
813 sequence of decimal digits that rounds to x. Previous behaviour was
814 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000815 Another minor difference is that the new repr switches to
816 exponential notation at 1e16 instead of the previous 1e17; this
817 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000818
819 There's a new sys attribute sys.float_repr_style, which takes
820 the value 'short' to indicate that we're using short float repr,
821 and 'legacy' if the short float repr isn't available for one
822 reason or another.
823
824 The float repr change involves incorporating David Gay's 'perfect
825 rounding' code into the Python core (it's in Python/dtoa.c). As a
826 secondary consequence, all string-to-float and float-to-string
827 conversions (including all float formatting operations) will be
828 correctly rounded on these platforms.
829
830 See issue 1580 discussions for details of platforms for which
831 this change does not apply.
832
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000833- Issue #5759: float() didn't call __float__ on str subclasses.
834
Georg Brandlabc38772009-04-12 15:51:51 +0000835- The string.maketrans() function is deprecated; there is a new static method
836 maketrans() on the bytes and bytearray classes. This removes confusion about
837 the types string.maketrans() is supposed to work with, and mirrors the
838 methods available on the str class.
839
R. David Murraydc6da8a2009-04-09 22:16:43 +0000840- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
841 its clarity and its speed.
842
Matthias Klose091c7b12009-04-07 13:24:27 +0000843- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
844 to avoid compiler warnings.
845
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000846- Issue #3739: The unicode-internal encoder now reports the number of characters
847 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +0000925- Issue #1161031: fix readwrite select flag handling: POLLPRI now
926 results in a handle_expt_event call, not handle_read_event, and POLLERR
927 and POLLNVAL now call handle_close, not handle_expt_event. Also,
928 dispatcher now has an 'ignore_log_types' attribute for suppressing
929 log messages, which is set to 'warning' by default.
930
Matthias Klosea3d29e82009-04-07 13:13:10 +0000931- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
932 new arguments introduced in 2.5.

955- Issue #5354: New test support function import_fresh_module() makes
956 it easy to import both normal and optimised versions of modules.
957 test_heapq and test_warnings have been adjusted to use it, tests for
958 other modules with both C and Python implementations in the stdlib
959 can be adjusted to use it over time.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001001- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1002 the end sys.path, for compatibility with the system install of Python.
1003
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001004- Issue #4688: Add a heuristic so that tuples and dicts containing only
1005 untrackable objects are not tracked by the garbage collector. This can
1006 reduce the size of collections and therefore the garbage collection overhead
1007 on long-running programs, depending on their particular use of datatypes.
1008
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001009- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1014 2**15 for the internal representation of integers, for performance
1015 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1016 --enable-big-digits option to configure, which overrides the
1017 default. Add sys.int_info structseq to provide information about
1018 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00001020- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1021 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1022 and sizeof(Py_UNICODE) == 2.
1023
Eric Smith8ec90442009-03-14 12:29:34 +00001024- Issue #5237: Allow auto-numbered fields in str.format(). For

1026
Antoine Pitrou652e7072009-03-13 19:25:20 +00001027- Issue #5392: when a very low recursion limit was set, the interpreter would
1028 abort with a fatal error after the recursion limit was hit twice.
1029
Matthias Klose042f1332009-04-04 14:32:42 +00001030- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1076
Lars Gustäbel42e00912009-03-22 20:34:29 +00001077- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1078 forever on incomplete input. That caused tarfile.open() to hang when used
1079 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1080 partial bzip2 compressed data.
1081
Mark Dickinson79f52032009-03-17 23:12:51 +00001082- Issue #2110: Add support for thousands separator and 'n' type

1150 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1151 evaluation loop is compiled with a new dispatch mechanism which gives
1152 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitrou8043cf82009-01-09 19:54:29 +00001193 having been closed (for instance, a read() call could return some
1194 previously buffered data). Patch by Dmitry Vasiliev.
1195
Antoine Pitrou05608432009-01-09 18:53:14 +00001196- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1197 flag to work properly. Furthermore, when specifying -u, the text stdout
1198 and stderr streams have line-by-line buffering enabled (the default being
1199 to buffer arbitrary chunks of data).
1200
Raymond Hettinger35631532009-01-09 03:58:09 +00001201- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1202 instead of ints (reducing its size from 4 to 8 times thereby reducing
1203 Python's overall memory).
1204
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001205- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1206 an existing .py counterpart, override the co_filename attributes of all
1207 code objects if the original filename is obsolete (which can happen if the
1208 file has been renamed, moved, or if it is accessed through different paths).
1209 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1210
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001211- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1212 one byte. Also fixes the meaning of len() so that it returns the number of
1213 items, rather than the size in bytes.
1214
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001215- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1216

1602
Antoine Pitrou08838b62009-01-21 00:55:13 +00001603- Issue #5008: When a file is opened in append mode with the new IO library,
1604 do an explicit seek to the end of file (so that e.g. tell() returns the
1605 file size rather than 0). This is consistent with the behaviour of the
