169 to execute file paths that refer to source or compiled Python files as well

206 reading from stdin so that existing input does not confuse it and
207 lead to incorrect entry or an IOError. It also properly flushes it
208 afterwards to avoid the terminal echoing the input afterwards on
209 OSes such as Solaris.
210
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000211- Issue #7233: Fix a number of two-argument Decimal methods to make

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

739Core and Builtins
740-----------------
741
Mark Dickinson865e01a2009-05-07 16:37:01 +0000742- Issue #5914: Add new C API function PyOS_string_to_double, and
743 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
744
Eric Smith741191f2009-05-06 13:08:15 +0000745- Issue #3382: float.__format__, complex.__format__, and %-formatting
746 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
747 affects nan -> NAN and inf -> INF.
748
Mark Hammond5a607a32009-05-06 08:04:54 +0000749- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
750 in all operations, including splitdrive, split, etc. splitunc() now issues
751 a PendingDeprecation warning.
752
Eric Smith63376222009-05-05 14:04:18 +0000753- Issue #5920: For float.__format__, change the behavior with the
754 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
755 to be like 'g' but with at least one decimal point and with a
756 default precision of 12. Previously, the behavior the same but with
757 a default precision of 6. This more closely matches str(), and
758 reduces surprises when adding alignment flags to the empty
759 presentation type. This also affects the new complex.__format__ in
760 the same way.
761
Martin v. Löwis011e8422009-05-05 04:43:17 +0000762- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
763
R. David Murrayb18500d2009-05-04 22:59:07 +0000764- Issue #5890: in subclasses of 'property' the __doc__ attribute was
765 shadowed by classtype's, even if it was None. property now
766 inserts the __doc__ into the subclass instance __dict__.
767
Antoine Pitrou244651a2009-05-04 18:56:13 +0000768- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
769 sequences. Patch by Nick Barnes and Victor Stinner.
770
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000771- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000772
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000773- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
774 received a new method, detach(). detach() disconnects the underlying stream
775 from the buffer or text IO and returns it.
776
Mark Dickinson33841c32009-05-01 15:37:04 +0000777- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
778 floats with absolute value over 1e50. Also remove length
779 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
780 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000781
Eric Smith741191f2009-05-06 13:08:15 +0000782- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000783 format(complex(1, 2./3), '.5') now produces a sensible result.
784
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000785- Issue #5864: Fix empty format code formatting for floats so that it
786 never gives more than the requested number of significant digits.
787
Eric Smith6dc46f52009-04-27 20:39:49 +0000788- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
789 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
790
Eric Smithcc32a112009-04-26 21:35:14 +0000791- Issue #5835: Deprecate PyOS_ascii_formatd.
792
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000793- Issue #4971: Fix titlecase for characters that are their own
794 titlecase, but not their own uppercase.
795
Benjamin Peterson193152c2009-04-25 01:08:45 +0000796- Issue #5283: Setting __class__ in __del__ caused a segfault.
797
Mark Dickinsonad476da2009-04-23 19:14:16 +0000798- Issue #5816: complex(repr(z)) now recovers z exactly, even when
799 z involves nans, infs or negative zeros.
800
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000801- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000802
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000803- Issue #1869 (and many duplicates): make round(x, n) correctly
804 rounded for a float x, by using the decimal <-> binary conversions
805 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
806 consistently agrees with format(x, '.2f').
807
Benjamin Petersonae937c02009-04-18 20:54:08 +0000808- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
809 some builtin types.
810
Eric Smith0923d1d2009-04-16 20:16:10 +0000811- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
812
Eric Smith35e84722009-04-16 20:21:28 +0000813- Issue #5515: str.format() type 'n' combined with commas and leading
814 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000815
816- Implement PEP 378, Format Specifier for Thousands Separator, for
817 floats.
818
Mark Dickinson3370cce2009-04-17 22:40:53 +0000819- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000820 1e11, not 1e12. This avoids printing 13 significant digits in
821 situations where only 12 of them are correct. Example problem
822 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
823 long time.)
824
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000825- Issue #1580: On most platforms, use a 'short' float repr: for a
826 finite float x, repr(x) now outputs a string based on the shortest
827 sequence of decimal digits that rounds to x. Previous behaviour was
828 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000829 Another minor difference is that the new repr switches to
830 exponential notation at 1e16 instead of the previous 1e17; this
831 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000832
833 There's a new sys attribute sys.float_repr_style, which takes
834 the value 'short' to indicate that we're using short float repr,
835 and 'legacy' if the short float repr isn't available for one
836 reason or another.
837
838 The float repr change involves incorporating David Gay's 'perfect
839 rounding' code into the Python core (it's in Python/dtoa.c). As a
840 secondary consequence, all string-to-float and float-to-string
841 conversions (including all float formatting operations) will be
842 correctly rounded on these platforms.
843
844 See issue 1580 discussions for details of platforms for which
845 this change does not apply.
846
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000847- Issue #5759: float() didn't call __float__ on str subclasses.
848
Georg Brandlabc38772009-04-12 15:51:51 +0000849- The string.maketrans() function is deprecated; there is a new static method
850 maketrans() on the bytes and bytearray classes. This removes confusion about
851 the types string.maketrans() is supposed to work with, and mirrors the
852 methods available on the str class.
853
R. David Murraydc6da8a2009-04-09 22:16:43 +0000854- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
855 its clarity and its speed.
856
Matthias Klose091c7b12009-04-07 13:24:27 +0000857- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
858 to avoid compiler warnings.
859
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000860- Issue #3739: The unicode-internal encoder now reports the number of characters
861 consumed like any other encoder (instead of the number of bytes).

1019 untrackable objects are not tracked by the garbage collector. This can
1020 reduce the size of collections and therefore the garbage collection overhead
1021 on long-running programs, depending on their particular use of datatypes.

1092 forever on incomplete input. That caused tarfile.open() to hang when used
1093 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1094 partial bzip2 compressed data.

1216 instead of ints (reducing its size from 4 to 8 times thereby reducing

Antoine Pitroud35cbf62009-01-06 19:02:24 +00001219- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1220 an existing .py counterpart, override the co_filename attributes of all
1221 code objects if the original filename is obsolete (which can happen if the
1222 file has been renamed, moved, or if it is accessed through different paths).

1269
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001270- Issue #4445: Replace "sizeof(PyBytesObject)" with
1271 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1272 bytes instances. On a typical machine this saves 3 bytes of memory
1273 (on average) per allocation of a bytes instance.
1274
Christian Heimesa872de52008-12-05 08:26:55 +00001275- Issue #4533: File read operation was dreadfully slow due to a slowly

1277 Python 2.x.
1278
Antoine Pitrou5504e892008-12-06 21:27:53 +00001279- Issue #4509: Various issues surrounding resize of bytearray objects to

1281
Georg Brandlf9734072008-12-07 15:30:06 +00001282- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1283 method on file objects with closefd=False. The file descriptor is still
1284 kept open but the file object behaves like a closed file. The ``FileIO``
1285 object also got a new readonly attribute ``closefd``.

1295 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1296 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1297 of using the replace error handler in PyUnicode_DecodeUTF8().
