658 the signals should be handled. In many cases this order wasn't
659 being followed, leading to the wrong Python exception being raised.

690 witnessed in test_httpservers.
691
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000692- Issue #8524: When creating an SSL socket, the timeout value of the
693 original socket wasn't retained (instead, a socket with a positive timeout
694 would be turned into a non-blocking SSL socket).
695
Antoine Pitrouec146182010-04-24 21:30:20 +0000696- Issue #5103: SSL handshake would ignore the socket timeout and block
697 indefinitely if the other end didn't respond.
698
699- The do_handshake() method of SSL objects now adjusts the blocking mode of
700 the SSL structure if necessary (as other methods already do).

Ronald Oussoren47076f72010-07-23 15:46:03 +0000798- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
799 compared to other unix systems. In particular, os.getgroups() does
800 not reflect any changes made using os.setgroups() but basicly always
801 returns the same information as the id command.

Martin v. Löwis70ccd162009-05-24 19:47:22 +00001750- Issue #6050: Don't fail extracting a directory from a zipfile if
1751 the directory already exists.
1752
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001753- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1754 than an int, which makes some operations possible under 64-bit Linux (e.g.
1755 DN_MULTISHOT with F_NOTIFY).
1756
Antoine Pitrou716c4442009-05-23 19:04:03 +00001757- Issue #5761: Add the name of the underlying file to the repr() of various

1764 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1765 a process identifier type wider than the standard C integer type.
1766

1778
Antoine Pitroue4501852009-05-14 18:55:55 +00001779- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1780 library. This means, for example, that opening an UTF-16 text file in
1781 append mode doesn't add a BOM at the end of the file if the file isn't
1782 empty.
1783
R. David Murray74b89242009-05-13 17:33:03 +00001784- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1785 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1786 corrects a pydoc regression.
1787
Georg Brandl442d3b32010-08-01 22:33:12 +00001788- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001789 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001831
1832Core and Builtins
1833-----------------
1834
Mark Dickinson865e01a2009-05-07 16:37:01 +00001835- Issue #5914: Add new C API function PyOS_string_to_double, and
1836 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1837
Eric Smith741191f2009-05-06 13:08:15 +00001838- Issue #3382: float.__format__, complex.__format__, and %-formatting
1839 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1840 affects nan -> NAN and inf -> INF.
1841
Mark Hammond5a607a32009-05-06 08:04:54 +00001842- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1843 in all operations, including splitdrive, split, etc. splitunc() now issues
1844 a PendingDeprecation warning.
1845
Eric Smith63376222009-05-05 14:04:18 +00001846- Issue #5920: For float.__format__, change the behavior with the
1847 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1848 to be like 'g' but with at least one decimal point and with a
1849 default precision of 12. Previously, the behavior the same but with
1850 a default precision of 6. This more closely matches str(), and
1851 reduces surprises when adding alignment flags to the empty
1852 presentation type. This also affects the new complex.__format__ in
1853 the same way.
1854
Martin v. Löwis011e8422009-05-05 04:43:17 +00001855- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1856
R. David Murrayb18500d2009-05-04 22:59:07 +00001857- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1858 shadowed by classtype's, even if it was None. property now
1859 inserts the __doc__ into the subclass instance __dict__.
1860
Antoine Pitrou244651a2009-05-04 18:56:13 +00001861- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1862 sequences. Patch by Nick Barnes and Victor Stinner.
1863
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001864- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001865
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001866- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1867 received a new method, detach(). detach() disconnects the underlying stream
1868 from the buffer or text IO and returns it.
1869
Mark Dickinson33841c32009-05-01 15:37:04 +00001870- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1871 floats with absolute value over 1e50. Also remove length
1872 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1873 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001874
Eric Smith741191f2009-05-06 13:08:15 +00001875- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001876 format(complex(1, 2./3), '.5') now produces a sensible result.
1877
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001878- Issue #5864: Fix empty format code formatting for floats so that it
1879 never gives more than the requested number of significant digits.
1880
Eric Smith6dc46f52009-04-27 20:39:49 +00001881- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1882 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1883
Eric Smithcc32a112009-04-26 21:35:14 +00001884- Issue #5835: Deprecate PyOS_ascii_formatd.
1885
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001886- Issue #4971: Fix titlecase for characters that are their own
1887 titlecase, but not their own uppercase.
1888
Benjamin Peterson193152c2009-04-25 01:08:45 +00001889- Issue #5283: Setting __class__ in __del__ caused a segfault.
1890
Mark Dickinsonad476da2009-04-23 19:14:16 +00001891- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1892 z involves nans, infs or negative zeros.
1893
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001894- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001895
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001896- Issue #1869 (and many duplicates): make round(x, n) correctly
1897 rounded for a float x, by using the decimal <-> binary conversions
1898 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1899 consistently agrees with format(x, '.2f').
1900
Benjamin Petersonae937c02009-04-18 20:54:08 +00001901- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1902 some builtin types.
1903
Eric Smith0923d1d2009-04-16 20:16:10 +00001904- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1905
Eric Smith35e84722009-04-16 20:21:28 +00001906- Issue #5515: str.format() type 'n' combined with commas and leading
1907 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001908
1909- Implement PEP 378, Format Specifier for Thousands Separator, for
1910 floats.
1911
Mark Dickinson3370cce2009-04-17 22:40:53 +00001912- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001913 1e11, not 1e12. This avoids printing 13 significant digits in
1914 situations where only 12 of them are correct. Example problem
1915 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1916 long time.)
1917
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001918- Issue #1580: On most platforms, use a 'short' float repr: for a
1919 finite float x, repr(x) now outputs a string based on the shortest
1920 sequence of decimal digits that rounds to x. Previous behaviour was
1921 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001922 Another minor difference is that the new repr switches to
1923 exponential notation at 1e16 instead of the previous 1e17; this
1924 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001925
1926 There's a new sys attribute sys.float_repr_style, which takes
1927 the value 'short' to indicate that we're using short float repr,
1928 and 'legacy' if the short float repr isn't available for one
1929 reason or another.
1930
1931 The float repr change involves incorporating David Gay's 'perfect
1932 rounding' code into the Python core (it's in Python/dtoa.c). As a
1933 secondary consequence, all string-to-float and float-to-string
1934 conversions (including all float formatting operations) will be
1935 correctly rounded on these platforms.
1936
Georg Brandl442d3b32010-08-01 22:33:12 +00001937 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001938 this change does not apply.
1939
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001940- Issue #5759: float() didn't call __float__ on str subclasses.
1941
Georg Brandlabc38772009-04-12 15:51:51 +00001942- The string.maketrans() function is deprecated; there is a new static method
1943 maketrans() on the bytes and bytearray classes. This removes confusion about
1944 the types string.maketrans() is supposed to work with, and mirrors the
1945 methods available on the str class.
1946
R. David Murraydc6da8a2009-04-09 22:16:43 +00001947- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1948 its clarity and its speed.
1949
Matthias Klose091c7b12009-04-07 13:24:27 +00001950- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1951 to avoid compiler warnings.
1952
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001953- Issue #3739: The unicode-internal encoder now reports the number of characters
1954 consumed like any other encoder (instead of the number of bytes).

2110
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002111- Issue #4688: Add a heuristic so that tuples and dicts containing only
2112 untrackable objects are not tracked by the garbage collector. This can
2113 reduce the size of collections and therefore the garbage collection overhead
2114 on long-running programs, depending on their particular use of datatypes.

2183
Lars Gustäbel42e00912009-03-22 20:34:29 +00002184- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2185 forever on incomplete input. That caused tarfile.open() to hang when used
2186 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2187 partial bzip2 compressed data.
2188
Mark Dickinson79f52032009-03-17 23:12:51 +00002189- Issue #2110: Add support for thousands separator and 'n' type

2301 previously buffered data). Patch by Dmitry Vasiliev.
2302
Antoine Pitrou05608432009-01-09 18:53:14 +00002303- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2304 flag to work properly. Furthermore, when specifying -u, the text stdout
2305 and stderr streams have line-by-line buffering enabled (the default being
2306 to buffer arbitrary chunks of data).
2307
Raymond Hettinger35631532009-01-09 03:58:09 +00002308- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2309 instead of ints (reducing its size from 4 to 8 times thereby reducing
2310 Python's overall memory).
2311
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002312- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2313 an existing .py counterpart, override the co_filename attributes of all
2314 code objects if the original filename is obsolete (which can happen if the
2315 file has been renamed, moved, or if it is accessed through different paths).
2316 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2317
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002318- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2319 one byte. Also fixes the meaning of len() so that it returns the number of
2320 items, rather than the size in bytes.
2321
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002322- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2388 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2389 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2390 of using the replace error handler in PyUnicode_DecodeUTF8().

2667
Antoine Pitrou08838b62009-01-21 00:55:13 +00002668- Issue #5008: When a file is opened in append mode with the new IO library,
2669 do an explicit seek to the end of file (so that e.g. tell() returns the
2670 file size rather than 0). This is consistent with the behaviour of the
2671 traditional 2.x file object.

2689
Jesse Noller6214edd2009-01-19 16:23:53 +00002690- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks

2701 appropriately when it is being used via socket.makefile() objects
2702 rather than delaying the close by waiting for garbage collection to do it.
2703

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002947- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2948 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2949 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2950 skip the tests if DISPLAY is defined but can't be used.
2951
R. David Murraya21e4ca2009-03-31 23:16:50 +00002952- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002953 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002954 from test support, which does the conversion.
2955
Guilherme Polo9de29af2009-01-28 20:40:48 +00002956- Issue #5083: New 'gui' resource for regrtest.
