647
Mark Dickinsonece06972010-05-04 14:37:14 +0000648- Issue #8567: Fix precedence of signals in Decimal module: when a
649 Decimal operation raises multiple signals and more than one of those
650 signals is trapped, the specification determines the order in which
651 the signals should be handled. In many cases this order wasn't
652 being followed, leading to the wrong Python exception being raised.

681 where the method could block indefinitely if called just before the
682 event loop started running. This also fixes the occasional freezes
683 witnessed in test_httpservers.
684
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000685- Issue #8524: When creating an SSL socket, the timeout value of the
686 original socket wasn't retained (instead, a socket with a positive timeout
687 would be turned into a non-blocking SSL socket).
688
Antoine Pitrouec146182010-04-24 21:30:20 +0000689- Issue #5103: SSL handshake would ignore the socket timeout and block
690 indefinitely if the other end didn't respond.
691
692- The do_handshake() method of SSL objects now adjusts the blocking mode of
693 the SSL structure if necessary (as other methods already do).
694
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000695- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
696 a non-infinite timeout. Also make that method friendlier with applications
697 wanting to continue using the socket in clear-text mode, by disabling
698 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Ronald Oussoren47076f72010-07-23 15:46:03 +0000791- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
792 compared to other unix systems. In particular, os.getgroups() does
793 not reflect any changes made using os.setgroups() but basicly always

1771
Antoine Pitroue4501852009-05-14 18:55:55 +00001772- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1773 library. This means, for example, that opening an UTF-16 text file in
1774 append mode doesn't add a BOM at the end of the file if the file isn't
1775 empty.
1776
R. David Murray74b89242009-05-13 17:33:03 +00001777- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1778 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1779 corrects a pydoc regression.
1780
Georg Brandl442d3b32010-08-01 22:33:12 +00001781- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001782 now it does. This also means getfp method now returns the real fp.

1825Core and Builtins
1826-----------------
1827
Mark Dickinson865e01a2009-05-07 16:37:01 +00001828- Issue #5914: Add new C API function PyOS_string_to_double, and
1829 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1830
Eric Smith741191f2009-05-06 13:08:15 +00001831- Issue #3382: float.__format__, complex.__format__, and %-formatting
1832 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1833 affects nan -> NAN and inf -> INF.
1834
Mark Hammond5a607a32009-05-06 08:04:54 +00001835- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1836 in all operations, including splitdrive, split, etc. splitunc() now issues
1837 a PendingDeprecation warning.
1838
Eric Smith63376222009-05-05 14:04:18 +00001839- Issue #5920: For float.__format__, change the behavior with the
1840 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1841 to be like 'g' but with at least one decimal point and with a
1842 default precision of 12. Previously, the behavior the same but with
1843 a default precision of 6. This more closely matches str(), and
1844 reduces surprises when adding alignment flags to the empty
1845 presentation type. This also affects the new complex.__format__ in
1846 the same way.
1847
Martin v. Löwis011e8422009-05-05 04:43:17 +00001848- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1849
R. David Murrayb18500d2009-05-04 22:59:07 +00001850- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1851 shadowed by classtype's, even if it was None. property now
1852 inserts the __doc__ into the subclass instance __dict__.
1853
Antoine Pitrou244651a2009-05-04 18:56:13 +00001854- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1855 sequences. Patch by Nick Barnes and Victor Stinner.
1856
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001857- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001858
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001859- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1860 received a new method, detach(). detach() disconnects the underlying stream
1861 from the buffer or text IO and returns it.
1862
Mark Dickinson33841c32009-05-01 15:37:04 +00001863- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1864 floats with absolute value over 1e50. Also remove length
1865 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1866 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001867
Eric Smith741191f2009-05-06 13:08:15 +00001868- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001869 format(complex(1, 2./3), '.5') now produces a sensible result.
1870
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001871- Issue #5864: Fix empty format code formatting for floats so that it
1872 never gives more than the requested number of significant digits.
1873
Eric Smith6dc46f52009-04-27 20:39:49 +00001874- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1875 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1876
Eric Smithcc32a112009-04-26 21:35:14 +00001877- Issue #5835: Deprecate PyOS_ascii_formatd.
1878
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001879- Issue #4971: Fix titlecase for characters that are their own
1880 titlecase, but not their own uppercase.
1881
Benjamin Peterson193152c2009-04-25 01:08:45 +00001882- Issue #5283: Setting __class__ in __del__ caused a segfault.
1883
Mark Dickinsonad476da2009-04-23 19:14:16 +00001884- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1885 z involves nans, infs or negative zeros.
1886
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001887- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001888
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001889- Issue #1869 (and many duplicates): make round(x, n) correctly
1890 rounded for a float x, by using the decimal <-> binary conversions
1891 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1892 consistently agrees with format(x, '.2f').
1893
Benjamin Petersonae937c02009-04-18 20:54:08 +00001894- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1895 some builtin types.
1896
Eric Smith0923d1d2009-04-16 20:16:10 +00001897- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1898
Eric Smith35e84722009-04-16 20:21:28 +00001899- Issue #5515: str.format() type 'n' combined with commas and leading
1900 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001901
1902- Implement PEP 378, Format Specifier for Thousands Separator, for
1903 floats.
1904
Mark Dickinson3370cce2009-04-17 22:40:53 +00001905- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001906 1e11, not 1e12. This avoids printing 13 significant digits in
1907 situations where only 12 of them are correct. Example problem
1908 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1909 long time.)
1910
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001911- Issue #1580: On most platforms, use a 'short' float repr: for a
1912 finite float x, repr(x) now outputs a string based on the shortest
1913 sequence of decimal digits that rounds to x. Previous behaviour was
1914 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001915 Another minor difference is that the new repr switches to
1916 exponential notation at 1e16 instead of the previous 1e17; this
1917 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001918
1919 There's a new sys attribute sys.float_repr_style, which takes
1920 the value 'short' to indicate that we're using short float repr,
1921 and 'legacy' if the short float repr isn't available for one
1922 reason or another.
1923
1924 The float repr change involves incorporating David Gay's 'perfect
1925 rounding' code into the Python core (it's in Python/dtoa.c). As a
1926 secondary consequence, all string-to-float and float-to-string
1927 conversions (including all float formatting operations) will be
1928 correctly rounded on these platforms.
1929
Georg Brandl442d3b32010-08-01 22:33:12 +00001930 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001931 this change does not apply.
1932
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001933- Issue #5759: float() didn't call __float__ on str subclasses.
1934
Georg Brandlabc38772009-04-12 15:51:51 +00001935- The string.maketrans() function is deprecated; there is a new static method
1936 maketrans() on the bytes and bytearray classes. This removes confusion about
1937 the types string.maketrans() is supposed to work with, and mirrors the
1938 methods available on the str class.
1939
R. David Murraydc6da8a2009-04-09 22:16:43 +00001940- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1941 its clarity and its speed.
1942
Matthias Klose091c7b12009-04-07 13:24:27 +00001943- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1944 to avoid compiler warnings.
1945
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001946- Issue #3739: The unicode-internal encoder now reports the number of characters
1947 consumed like any other encoder (instead of the number of bytes).

2083
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002084- Issue #5499: The 'c' code for argument parsing functions now only accepts a
2085 byte, and the 'C' code only accepts a unicode character.
2086
Georg Brandl406b3d82009-04-11 21:24:37 +00002087- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

2089
Brett Cannon0759dd62009-04-01 18:13:07 +00002090- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2091
Georg Brandlab6f2f62009-03-31 04:16:10 +00002092- Fix a segfault when running test_exceptions with coverage, caused by
2093 insufficient checks in accessors of Exception.__context__.
2094
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002095- Issue #5604: non-ASCII characters in module name passed to
2096 imp.find_module() were converted to UTF-8 while the path is
2097 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00002099- Issue #5126: str.isprintable() returned False for space characters.
2100
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002101- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2102 the end sys.path, for compatibility with the system install of Python.
2103
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002104- Issue #4688: Add a heuristic so that tuples and dicts containing only
2105 untrackable objects are not tracked by the garbage collector. This can
2106 reduce the size of collections and therefore the garbage collection overhead
2107 on long-running programs, depending on their particular use of datatypes.
2108
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002109- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2121 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2122 and sizeof(Py_UNICODE) == 2.
2123
Eric Smith8ec90442009-03-14 12:29:34 +00002124- Issue #5237: Allow auto-numbered fields in str.format(). For

2126
Antoine Pitrou652e7072009-03-13 19:25:20 +00002127- Issue #5392: when a very low recursion limit was set, the interpreter would
2128 abort with a fatal error after the recursion limit was hit twice.
2129
Matthias Klose042f1332009-04-04 14:32:42 +00002130- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2176
Lars Gustäbel42e00912009-03-22 20:34:29 +00002177- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2178 forever on incomplete input. That caused tarfile.open() to hang when used
2179 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2180 partial bzip2 compressed data.
2181
Mark Dickinson79f52032009-03-17 23:12:51 +00002182- Issue #2110: Add support for thousands separator and 'n' type

2250 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2251 evaluation loop is compiled with a new dispatch mechanism which gives
2252 speedups of up to 20%, depending on the system, on various benchmarks.

2268 to str, bytes and bytearray could be optimized away by the compiler, letting
2269 the interpreter segfault instead of raising an error.
2270
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002271- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2295
Antoine Pitrou05608432009-01-09 18:53:14 +00002296- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2297 flag to work properly. Furthermore, when specifying -u, the text stdout
2298 and stderr streams have line-by-line buffering enabled (the default being
2299 to buffer arbitrary chunks of data).
2300
Raymond Hettinger35631532009-01-09 03:58:09 +00002301- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2302 instead of ints (reducing its size from 4 to 8 times thereby reducing

2304
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002305- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2306 an existing .py counterpart, override the co_filename attributes of all
2307 code objects if the original filename is obsolete (which can happen if the
2308 file has been renamed, moved, or if it is accessed through different paths).
2309 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2310
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002311- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2312 one byte. Also fixes the meaning of len() so that it returns the number of
2313 items, rather than the size in bytes.
2314
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002315- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2325
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002326- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2327 where the tp_hash and tp_dict slots are both NULL.
2328
Georg Brandlccc47b62008-12-28 11:44:14 +00002329- Issue #4759: None is now allowed as the first argument of

2381 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2662 do an explicit seek to the end of file (so that e.g. tell() returns the

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002940- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2941 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2942 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2943 skip the tests if DISPLAY is defined but can't be used.
2944
R. David Murraya21e4ca2009-03-31 23:16:50 +00002945- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002946 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002947 from test support, which does the conversion.
2948
Guilherme Polo9de29af2009-01-28 20:40:48 +00002949- Issue #5083: New 'gui' resource for regrtest.
