675 Decimal operation raises multiple signals and more than one of those
676 signals is trapped, the specification determines the order in which
677 the signals should be handled. In many cases this order wasn't
678 being followed, leading to the wrong Python exception being raised.
679
Antoine Pitroufaf90072010-05-03 16:58:19 +0000680- Issue #7865: The close() method of :mod:`io` objects should not swallow

705
Antoine Pitroue3123912010-04-25 22:26:08 +0000706- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
707 where the method could block indefinitely if called just before the
708 event loop started running. This also fixes the occasional freezes
709 witnessed in test_httpservers.
710
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000711- Issue #8524: When creating an SSL socket, the timeout value of the
712 original socket wasn't retained (instead, a socket with a positive timeout
713 would be turned into a non-blocking SSL socket).
714
Antoine Pitrouec146182010-04-24 21:30:20 +0000715- Issue #5103: SSL handshake would ignore the socket timeout and block
716 indefinitely if the other end didn't respond.
717
718- The do_handshake() method of SSL objects now adjusts the blocking mode of
719 the SSL structure if necessary (as other methods already do).
720
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000721- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
722 a non-infinite timeout. Also make that method friendlier with applications
723 wanting to continue using the socket in clear-text mode, by disabling
724 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

735 the _ssl extension, such that verification of some SSL certificates

751
Victor Stinnerf7351b42010-04-13 11:09:22 +0000752- Issue #8383: pickle and pickletools use surrogatepass error handler when
753 encoding unicode as utf8 to support lone surrogates and stay compatible with
754 Python 2.x and 3.0

757
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000758- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

760 Initial patch by Bertrand Janin.
761
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000762- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
763 didn't support chflags() (for example ZFS under FreeBSD). The error is
764 now silenced.
765
Antoine Pitroued6c8932010-03-26 19:38:11 +0000766- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
767 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
768 reads and writes are always retried by OpenSSL itself.

Ronald Oussoren47076f72010-07-23 15:46:03 +0000817- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
818 compared to other unix systems. In particular, os.getgroups() does
819 not reflect any changes made using os.setgroups() but basicly always
820 returns the same information as the id command.
821
822 os.getgroups() can now return more than 16 groups on MacOSX.

1746 rejected; (2) parsing of strings representing infinities and nans
1747 was locale aware; and (3) the interpretation of fromhex('-nan')
1748 didn't match that of float('-nan').

1852-----------------
1853
Mark Dickinson865e01a2009-05-07 16:37:01 +00001854- Issue #5914: Add new C API function PyOS_string_to_double, and
1855 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1856
Eric Smith741191f2009-05-06 13:08:15 +00001857- Issue #3382: float.__format__, complex.__format__, and %-formatting
1858 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1859 affects nan -> NAN and inf -> INF.
1860
Mark Hammond5a607a32009-05-06 08:04:54 +00001861- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1862 in all operations, including splitdrive, split, etc. splitunc() now issues
1863 a PendingDeprecation warning.
1864
Eric Smith63376222009-05-05 14:04:18 +00001865- Issue #5920: For float.__format__, change the behavior with the
1866 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1867 to be like 'g' but with at least one decimal point and with a
1868 default precision of 12. Previously, the behavior the same but with
1869 a default precision of 6. This more closely matches str(), and
1870 reduces surprises when adding alignment flags to the empty
1871 presentation type. This also affects the new complex.__format__ in
1872 the same way.
1873
Martin v. Löwis011e8422009-05-05 04:43:17 +00001874- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1875
R. David Murrayb18500d2009-05-04 22:59:07 +00001876- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1877 shadowed by classtype's, even if it was None. property now
1878 inserts the __doc__ into the subclass instance __dict__.
1879
Antoine Pitrou244651a2009-05-04 18:56:13 +00001880- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1881 sequences. Patch by Nick Barnes and Victor Stinner.
1882
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001883- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001884
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001885- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1886 received a new method, detach(). detach() disconnects the underlying stream
1887 from the buffer or text IO and returns it.
1888
Mark Dickinson33841c32009-05-01 15:37:04 +00001889- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1890 floats with absolute value over 1e50. Also remove length
1891 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1892 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001893
Eric Smith741191f2009-05-06 13:08:15 +00001894- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001895 format(complex(1, 2./3), '.5') now produces a sensible result.
1896
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001897- Issue #5864: Fix empty format code formatting for floats so that it
1898 never gives more than the requested number of significant digits.
1899
Eric Smith6dc46f52009-04-27 20:39:49 +00001900- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1901 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1902
Eric Smithcc32a112009-04-26 21:35:14 +00001903- Issue #5835: Deprecate PyOS_ascii_formatd.
1904
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001905- Issue #4971: Fix titlecase for characters that are their own
1906 titlecase, but not their own uppercase.
1907
Benjamin Peterson193152c2009-04-25 01:08:45 +00001908- Issue #5283: Setting __class__ in __del__ caused a segfault.
1909
Mark Dickinsonad476da2009-04-23 19:14:16 +00001910- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1911 z involves nans, infs or negative zeros.
1912
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001913- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001914
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001915- Issue #1869 (and many duplicates): make round(x, n) correctly
1916 rounded for a float x, by using the decimal <-> binary conversions
1917 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1918 consistently agrees with format(x, '.2f').
1919
Benjamin Petersonae937c02009-04-18 20:54:08 +00001920- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1921 some builtin types.
1922
Eric Smith0923d1d2009-04-16 20:16:10 +00001923- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1924
Eric Smith35e84722009-04-16 20:21:28 +00001925- Issue #5515: str.format() type 'n' combined with commas and leading
1926 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001927
1928- Implement PEP 378, Format Specifier for Thousands Separator, for
1929 floats.
1930
Mark Dickinson3370cce2009-04-17 22:40:53 +00001931- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001932 1e11, not 1e12. This avoids printing 13 significant digits in
1933 situations where only 12 of them are correct. Example problem
1934 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1935 long time.)
1936
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001937- Issue #1580: On most platforms, use a 'short' float repr: for a
1938 finite float x, repr(x) now outputs a string based on the shortest
1939 sequence of decimal digits that rounds to x. Previous behaviour was
1940 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001941 Another minor difference is that the new repr switches to
1942 exponential notation at 1e16 instead of the previous 1e17; this
1943 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001944
1945 There's a new sys attribute sys.float_repr_style, which takes
1946 the value 'short' to indicate that we're using short float repr,
1947 and 'legacy' if the short float repr isn't available for one
1948 reason or another.
1949
1950 The float repr change involves incorporating David Gay's 'perfect
1951 rounding' code into the Python core (it's in Python/dtoa.c). As a
1952 secondary consequence, all string-to-float and float-to-string
1953 conversions (including all float formatting operations) will be
1954 correctly rounded on these platforms.
1955
Georg Brandl442d3b32010-08-01 22:33:12 +00001956 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001957 this change does not apply.
1958
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001959- Issue #5759: float() didn't call __float__ on str subclasses.
1960
Georg Brandlabc38772009-04-12 15:51:51 +00001961- The string.maketrans() function is deprecated; there is a new static method
1962 maketrans() on the bytes and bytearray classes. This removes confusion about
1963 the types string.maketrans() is supposed to work with, and mirrors the
1964 methods available on the str class.
1965
R. David Murraydc6da8a2009-04-09 22:16:43 +00001966- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1967 its clarity and its speed.
1968
Matthias Klose091c7b12009-04-07 13:24:27 +00001969- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1970 to avoid compiler warnings.
1971
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001972- Issue #3739: The unicode-internal encoder now reports the number of characters
1973 consumed like any other encoder (instead of the number of bytes).

2131 untrackable objects are not tracked by the garbage collector. This can
2132 reduce the size of collections and therefore the garbage collection overhead

2204 forever on incomplete input. That caused tarfile.open() to hang when used
2205 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2206 partial bzip2 compressed data.
2207

Raymond Hettinger35631532009-01-09 03:58:09 +00002327- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2328 instead of ints (reducing its size from 4 to 8 times thereby reducing

2332 an existing .py counterpart, override the co_filename attributes of all
2333 code objects if the original filename is obsolete (which can happen if the
2334 file has been renamed, moved, or if it is accessed through different paths).

2381
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002382- Issue #4445: Replace "sizeof(PyBytesObject)" with
2383 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

2389 Python 2.x.
2390
Antoine Pitrou5504e892008-12-06 21:27:53 +00002391- Issue #4509: Various issues surrounding resize of bytearray objects to

2393
Georg Brandlf9734072008-12-07 15:30:06 +00002394- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2395 method on file objects with closefd=False. The file descriptor is still
2396 kept open but the file object behaves like a closed file. The ``FileIO``
2397 object also got a new readonly attribute ``closefd``.

2407 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2408 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2409 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00002687- Issue #5008: When a file is opened in append mode with the new IO library,
2688 do an explicit seek to the end of file (so that e.g. tell() returns the
