Victor Stinnerf4ee5882010-05-15 21:05:33 +0000622- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
623 error messages when accessing undefined class attributes because of the cheap
Giampaolo Rodolàc2f1dca2010-05-06 18:37:34 +0000624 inheritance with the underlying socket object.
625
R. David Murrayf870d872010-05-06 01:53:03 +0000626- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

637
Mark Dickinsonece06972010-05-04 14:37:14 +0000638- Issue #8567: Fix precedence of signals in Decimal module: when a
639 Decimal operation raises multiple signals and more than one of those
640 signals is trapped, the specification determines the order in which
641 the signals should be handled. In many cases this order wasn't
642 being followed, leading to the wrong Python exception being raised.
643
Antoine Pitroufaf90072010-05-03 16:58:19 +0000644- Issue #7865: The close() method of :mod:`io` objects should not swallow

652 not just SIGCHLD.
653
Lars Gustäbelf7317f92010-04-29 15:42:25 +0000654- Issue #8464: tarfile no longer creates files with execute permissions set

668 sys.getfilesystemencoding() instead of sys.getdefautltencoding()
669
Antoine Pitroue3123912010-04-25 22:26:08 +0000670- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
671 where the method could block indefinitely if called just before the
672 event loop started running. This also fixes the occasional freezes
673 witnessed in test_httpservers.
674
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000675- Issue #8524: When creating an SSL socket, the timeout value of the
676 original socket wasn't retained (instead, a socket with a positive timeout
677 would be turned into a non-blocking SSL socket).
678
Antoine Pitrouec146182010-04-24 21:30:20 +0000679- Issue #5103: SSL handshake would ignore the socket timeout and block
680 indefinitely if the other end didn't respond.
681
682- The do_handshake() method of SSL objects now adjusts the blocking mode of
683 the SSL structure if necessary (as other methods already do).
684
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000685- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
686 a non-infinite timeout. Also make that method friendlier with applications
687 wanting to continue using the socket in clear-text mode, by disabling
688 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

693 iterator. Patch by Gregory Nofi.
694

697
Antoine Pitrouda6902c2010-04-21 19:52:52 +0000698- Issue #8484: Load all ciphers and digest algorithms when initializing
699 the _ssl extension, such that verification of some SSL certificates
700 doesn't fail because of an "unknown algorithm".
701
Giampaolo Rodolàf5279402010-04-19 22:10:56 +0000702- Issue #4814: timeout parameter is now applied also for connections resulting

R. David Murray84ee3102010-04-14 19:05:38 +0000714- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
715
Victor Stinnerf7351b42010-04-13 11:09:22 +0000716- Issue #8383: pickle and pickletools use surrogatepass error handler when
717 encoding unicode as utf8 to support lone surrogates and stay compatible with
718 Python 2.x and 3.0
719
Florent Xicluna9b0e9182010-03-28 11:42:38 +0000720- Issue #8179: Fix macpath.realpath() on a non-existing path.
721
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000722- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

724 Initial patch by Bertrand Janin.
725
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000726- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
727 didn't support chflags() (for example ZFS under FreeBSD). The error is
728 now silenced.
729
Antoine Pitroued6c8932010-03-26 19:38:11 +0000730- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
731 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
732 reads and writes are always retried by OpenSSL itself.

780
Ronald Oussoren47076f72010-07-23 15:46:03 +0000781- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
782 compared to other unix systems. In particular, os.getgroups() does
783 not reflect any changes made using os.setgroups() but basicly always
784 returns the same information as the id command.
785
786 os.getgroups() can now return more than 16 groups on MacOSX.

1761
Antoine Pitroue4501852009-05-14 18:55:55 +00001762- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1763 library. This means, for example, that opening an UTF-16 text file in
1764 append mode doesn't add a BOM at the end of the file if the file isn't
1765 empty.

1769 corrects a pydoc regression.
1770
Georg Brandl442d3b32010-08-01 22:33:12 +00001771- Issue #5955: aifc's close method did not close the file it wrapped,

1815Core and Builtins
1816-----------------
1817
Mark Dickinson865e01a2009-05-07 16:37:01 +00001818- Issue #5914: Add new C API function PyOS_string_to_double, and
1819 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1820
Eric Smith741191f2009-05-06 13:08:15 +00001821- Issue #3382: float.__format__, complex.__format__, and %-formatting
1822 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1823 affects nan -> NAN and inf -> INF.
1824
Mark Hammond5a607a32009-05-06 08:04:54 +00001825- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1826 in all operations, including splitdrive, split, etc. splitunc() now issues
1827 a PendingDeprecation warning.
1828
Eric Smith63376222009-05-05 14:04:18 +00001829- Issue #5920: For float.__format__, change the behavior with the
1830 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1831 to be like 'g' but with at least one decimal point and with a
1832 default precision of 12. Previously, the behavior the same but with
1833 a default precision of 6. This more closely matches str(), and
1834 reduces surprises when adding alignment flags to the empty
1835 presentation type. This also affects the new complex.__format__ in
1836 the same way.
1837
Martin v. Löwis011e8422009-05-05 04:43:17 +00001838- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1839
R. David Murrayb18500d2009-05-04 22:59:07 +00001840- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1841 shadowed by classtype's, even if it was None. property now
1842 inserts the __doc__ into the subclass instance __dict__.
1843
Antoine Pitrou244651a2009-05-04 18:56:13 +00001844- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1845 sequences. Patch by Nick Barnes and Victor Stinner.
1846
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001847- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001848
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001849- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1850 received a new method, detach(). detach() disconnects the underlying stream
1851 from the buffer or text IO and returns it.
1852
Mark Dickinson33841c32009-05-01 15:37:04 +00001853- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1854 floats with absolute value over 1e50. Also remove length
1855 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1856 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001857
Eric Smith741191f2009-05-06 13:08:15 +00001858- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001859 format(complex(1, 2./3), '.5') now produces a sensible result.
1860
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001861- Issue #5864: Fix empty format code formatting for floats so that it
1862 never gives more than the requested number of significant digits.
1863
Eric Smith6dc46f52009-04-27 20:39:49 +00001864- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1865 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1866
Eric Smithcc32a112009-04-26 21:35:14 +00001867- Issue #5835: Deprecate PyOS_ascii_formatd.
1868
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001869- Issue #4971: Fix titlecase for characters that are their own
1870 titlecase, but not their own uppercase.
1871
Benjamin Peterson193152c2009-04-25 01:08:45 +00001872- Issue #5283: Setting __class__ in __del__ caused a segfault.
1873
Mark Dickinsonad476da2009-04-23 19:14:16 +00001874- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1875 z involves nans, infs or negative zeros.
1876
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001877- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001878
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001879- Issue #1869 (and many duplicates): make round(x, n) correctly
1880 rounded for a float x, by using the decimal <-> binary conversions
1881 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1882 consistently agrees with format(x, '.2f').
1883
Benjamin Petersonae937c02009-04-18 20:54:08 +00001884- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1885 some builtin types.
1886
Eric Smith0923d1d2009-04-16 20:16:10 +00001887- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1888
Eric Smith35e84722009-04-16 20:21:28 +00001889- Issue #5515: str.format() type 'n' combined with commas and leading
1890 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001891
1892- Implement PEP 378, Format Specifier for Thousands Separator, for
1893 floats.
1894
Mark Dickinson3370cce2009-04-17 22:40:53 +00001895- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001896 1e11, not 1e12. This avoids printing 13 significant digits in
1897 situations where only 12 of them are correct. Example problem
1898 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1899 long time.)
1900
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001901- Issue #1580: On most platforms, use a 'short' float repr: for a
1902 finite float x, repr(x) now outputs a string based on the shortest
1903 sequence of decimal digits that rounds to x. Previous behaviour was
1904 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001905 Another minor difference is that the new repr switches to
1906 exponential notation at 1e16 instead of the previous 1e17; this
1907 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001908
1909 There's a new sys attribute sys.float_repr_style, which takes
1910 the value 'short' to indicate that we're using short float repr,
1911 and 'legacy' if the short float repr isn't available for one
1912 reason or another.
1913
1914 The float repr change involves incorporating David Gay's 'perfect
1915 rounding' code into the Python core (it's in Python/dtoa.c). As a
1916 secondary consequence, all string-to-float and float-to-string
1917 conversions (including all float formatting operations) will be
1918 correctly rounded on these platforms.
1919
Georg Brandl442d3b32010-08-01 22:33:12 +00001920 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001921 this change does not apply.
1922
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001923- Issue #5759: float() didn't call __float__ on str subclasses.
1924
Georg Brandlabc38772009-04-12 15:51:51 +00001925- The string.maketrans() function is deprecated; there is a new static method
1926 maketrans() on the bytes and bytearray classes. This removes confusion about
1927 the types string.maketrans() is supposed to work with, and mirrors the
1928 methods available on the str class.
1929
R. David Murraydc6da8a2009-04-09 22:16:43 +00001930- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1931 its clarity and its speed.
1932
Matthias Klose091c7b12009-04-07 13:24:27 +00001933- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1934 to avoid compiler warnings.
1935
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001936- Issue #3739: The unicode-internal encoder now reports the number of characters
1937 consumed like any other encoder (instead of the number of bytes).

2079
Brett Cannon0759dd62009-04-01 18:13:07 +00002080- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2081
Georg Brandlab6f2f62009-03-31 04:16:10 +00002082- Fix a segfault when running test_exceptions with coverage, caused by
2083 insufficient checks in accessors of Exception.__context__.
2084
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002085- Issue #5604: non-ASCII characters in module name passed to
2086 imp.find_module() were converted to UTF-8 while the path is
2087 converted to the default filesystem encoding, causing nonsense.

2090
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002091- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2092 the end sys.path, for compatibility with the system install of Python.
2093
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002094- Issue #4688: Add a heuristic so that tuples and dicts containing only
2095 untrackable objects are not tracked by the garbage collector. This can
2096 reduce the size of collections and therefore the garbage collection overhead
2097 on long-running programs, depending on their particular use of datatypes.
2098
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002099- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2111 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2112 and sizeof(Py_UNICODE) == 2.
2113
Eric Smith8ec90442009-03-14 12:29:34 +00002114- Issue #5237: Allow auto-numbered fields in str.format(). For

2116
Antoine Pitrou652e7072009-03-13 19:25:20 +00002117- Issue #5392: when a very low recursion limit was set, the interpreter would
2118 abort with a fatal error after the recursion limit was hit twice.
2119
Matthias Klose042f1332009-04-04 14:32:42 +00002120- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2166
Lars Gustäbel42e00912009-03-22 20:34:29 +00002167- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2168 forever on incomplete input. That caused tarfile.open() to hang when used
2169 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2170 partial bzip2 compressed data.
2171
Mark Dickinson79f52032009-03-17 23:12:51 +00002172- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00002220- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2221 it now forces its argument to double before testing for infinity.
2222
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002223- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2240 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2241 evaluation loop is compiled with a new dispatch mechanism which gives
2242 speedups of up to 20%, depending on the system, on various benchmarks.

2255 type to (void *).
2256
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002257- Issue #4935: The overflow checking code in the expandtabs() method common
2258 to str, bytes and bytearray could be optimized away by the compiler, letting
2259 the interpreter segfault instead of raising an error.
2260
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002261- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2284 previously buffered data). Patch by Dmitry Vasiliev.
2285
Antoine Pitrou05608432009-01-09 18:53:14 +00002286- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2287 flag to work properly. Furthermore, when specifying -u, the text stdout
2288 and stderr streams have line-by-line buffering enabled (the default being
2289 to buffer arbitrary chunks of data).
2290
Raymond Hettinger35631532009-01-09 03:58:09 +00002291- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2292 instead of ints (reducing its size from 4 to 8 times thereby reducing
2293 Python's overall memory).
2294
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002295- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2296 an existing .py counterpart, override the co_filename attributes of all
2297 code objects if the original filename is obsolete (which can happen if the
2298 file has been renamed, moved, or if it is accessed through different paths).
2299 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2300
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002301- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2302 one byte. Also fixes the meaning of len() so that it returns the number of
2303 items, rather than the size in bytes.
2304
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002305- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2306
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002307- Issue #4747: When the terminal does not use utf-8, executing a script with

2315
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002316- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2317 where the tp_hash and tp_dict slots are both NULL.
2318
Georg Brandlccc47b62008-12-28 11:44:14 +00002319- Issue #4759: None is now allowed as the first argument of
2320 bytearray.translate(). It was always allowed for bytes.translate().
2321

2371 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2373 of using the replace error handler in PyUnicode_DecodeUTF8().

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002617- Issue #5021: doctest.testfile() did not create __name__ and
Raymond Hettinger0f055172009-01-27 10:06:09 +00002618 collections.namedtuple() relied on __name__ being defined.
2619
2620- Backport importlib from Python 3.1. Only the import_module() function has

2649 be disabled, and not compiled.
2650
Antoine Pitrou08838b62009-01-21 00:55:13 +00002651- Issue #5008: When a file is opened in append mode with the new IO library,
2652 do an explicit seek to the end of file (so that e.g. tell() returns the
2653 file size rather than 0). This is consistent with the behaviour of the
2654 traditional 2.x file object.

2672
Jesse Noller6214edd2009-01-19 16:23:53 +00002673- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks

2684 appropriately when it is being used via socket.makefile() objects
2685 rather than delaying the close by waiting for garbage collection to do it.
2686
Raymond Hettingerb8baf632009-01-14 02:20:07 +00002687- Issue #1696199: Add collections.Counter() for rapid and convenient

2929
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002930- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2931 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2932 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2933 skip the tests if DISPLAY is defined but can't be used.
2934
R. David Murraya21e4ca2009-03-31 23:16:50 +00002935- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002936 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002937 from test support, which does the conversion.
2938
Guilherme Polo9de29af2009-01-28 20:40:48 +00002939- Issue #5083: New 'gui' resource for regrtest.
