630
Mark Dickinsonece06972010-05-04 14:37:14 +0000631- Issue #8567: Fix precedence of signals in Decimal module: when a
632 Decimal operation raises multiple signals and more than one of those
633 signals is trapped, the specification determines the order in which
634 the signals should be handled. In many cases this order wasn't
635 being followed, leading to the wrong Python exception being raised.
636
Antoine Pitroufaf90072010-05-03 16:58:19 +0000637- Issue #7865: The close() method of :mod:`io` objects should not swallow

645 not just SIGCHLD.
646

662
Antoine Pitroue3123912010-04-25 22:26:08 +0000663- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
664 where the method could block indefinitely if called just before the
665 event loop started running. This also fixes the occasional freezes
666 witnessed in test_httpservers.
667
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000668- Issue #8524: When creating an SSL socket, the timeout value of the
669 original socket wasn't retained (instead, a socket with a positive timeout
670 would be turned into a non-blocking SSL socket).
671
Antoine Pitrouec146182010-04-24 21:30:20 +0000672- Issue #5103: SSL handshake would ignore the socket timeout and block
673 indefinitely if the other end didn't respond.
674
675- The do_handshake() method of SSL objects now adjusts the blocking mode of
676 the SSL structure if necessary (as other methods already do).
677
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000678- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
679 a non-infinite timeout. Also make that method friendlier with applications
680 wanting to continue using the socket in clear-text mode, by disabling
681 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

689 collation name contains a surrogate character.
690
Antoine Pitrouda6902c2010-04-21 19:52:52 +0000691- Issue #8484: Load all ciphers and digest algorithms when initializing
692 the _ssl extension, such that verification of some SSL certificates
693 doesn't fail because of an "unknown algorithm".
694
Giampaolo Rodolàf5279402010-04-19 22:10:56 +0000695- Issue #4814: timeout parameter is now applied also for connections resulting

708
Victor Stinnerf7351b42010-04-13 11:09:22 +0000709- Issue #8383: pickle and pickletools use surrogatepass error handler when
710 encoding unicode as utf8 to support lone surrogates and stay compatible with
711 Python 2.x and 3.0
712
Florent Xicluna9b0e9182010-03-28 11:42:38 +0000713- Issue #8179: Fix macpath.realpath() on a non-existing path.

717 Initial patch by Bertrand Janin.
718
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000719- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
720 didn't support chflags() (for example ZFS under FreeBSD). The error is
721 now silenced.
722
Antoine Pitroued6c8932010-03-26 19:38:11 +0000723- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
724 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
725 reads and writes are always retried by OpenSSL itself.

Ronald Oussoren47076f72010-07-23 15:46:03 +0000774- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
775 compared to other unix systems. In particular, os.getgroups() does
776 not reflect any changes made using os.setgroups() but basicly always
777 returns the same information as the id command.
778
779 os.getgroups() can now return more than 16 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00001755- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1756 library. This means, for example, that opening an UTF-16 text file in
1757 append mode doesn't add a BOM at the end of the file if the file isn't
1758 empty.

1762 corrects a pydoc regression.
1763
Georg Brandl442d3b32010-08-01 22:33:12 +00001764- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001765 now it does. This also means getfp method now returns the real fp.

1808Core and Builtins
1809-----------------
1810
Mark Dickinson865e01a2009-05-07 16:37:01 +00001811- Issue #5914: Add new C API function PyOS_string_to_double, and
1812 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1813
Eric Smith741191f2009-05-06 13:08:15 +00001814- Issue #3382: float.__format__, complex.__format__, and %-formatting
1815 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1816 affects nan -> NAN and inf -> INF.
1817
Mark Hammond5a607a32009-05-06 08:04:54 +00001818- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1819 in all operations, including splitdrive, split, etc. splitunc() now issues
1820 a PendingDeprecation warning.
1821
Eric Smith63376222009-05-05 14:04:18 +00001822- Issue #5920: For float.__format__, change the behavior with the
1823 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1824 to be like 'g' but with at least one decimal point and with a
1825 default precision of 12. Previously, the behavior the same but with
1826 a default precision of 6. This more closely matches str(), and
1827 reduces surprises when adding alignment flags to the empty
1828 presentation type. This also affects the new complex.__format__ in
1829 the same way.
1830
Martin v. Löwis011e8422009-05-05 04:43:17 +00001831- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1832
R. David Murrayb18500d2009-05-04 22:59:07 +00001833- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1834 shadowed by classtype's, even if it was None. property now
1835 inserts the __doc__ into the subclass instance __dict__.
1836
Antoine Pitrou244651a2009-05-04 18:56:13 +00001837- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1838 sequences. Patch by Nick Barnes and Victor Stinner.
1839
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001840- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001841
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001842- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1843 received a new method, detach(). detach() disconnects the underlying stream
1844 from the buffer or text IO and returns it.
1845
Mark Dickinson33841c32009-05-01 15:37:04 +00001846- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1847 floats with absolute value over 1e50. Also remove length
1848 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1849 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001850
Eric Smith741191f2009-05-06 13:08:15 +00001851- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001852 format(complex(1, 2./3), '.5') now produces a sensible result.
1853
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001854- Issue #5864: Fix empty format code formatting for floats so that it
1855 never gives more than the requested number of significant digits.
1856
Eric Smith6dc46f52009-04-27 20:39:49 +00001857- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1858 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1859
Eric Smithcc32a112009-04-26 21:35:14 +00001860- Issue #5835: Deprecate PyOS_ascii_formatd.
1861
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001862- Issue #4971: Fix titlecase for characters that are their own
1863 titlecase, but not their own uppercase.
1864
Benjamin Peterson193152c2009-04-25 01:08:45 +00001865- Issue #5283: Setting __class__ in __del__ caused a segfault.
1866
Mark Dickinsonad476da2009-04-23 19:14:16 +00001867- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1868 z involves nans, infs or negative zeros.
1869
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001870- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001871
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001872- Issue #1869 (and many duplicates): make round(x, n) correctly
1873 rounded for a float x, by using the decimal <-> binary conversions
1874 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1875 consistently agrees with format(x, '.2f').
1876
Benjamin Petersonae937c02009-04-18 20:54:08 +00001877- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1878 some builtin types.
1879
Eric Smith0923d1d2009-04-16 20:16:10 +00001880- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1881
Eric Smith35e84722009-04-16 20:21:28 +00001882- Issue #5515: str.format() type 'n' combined with commas and leading
1883 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001884
1885- Implement PEP 378, Format Specifier for Thousands Separator, for
1886 floats.
1887
Mark Dickinson3370cce2009-04-17 22:40:53 +00001888- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001889 1e11, not 1e12. This avoids printing 13 significant digits in
1890 situations where only 12 of them are correct. Example problem
1891 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1892 long time.)
1893
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001894- Issue #1580: On most platforms, use a 'short' float repr: for a
1895 finite float x, repr(x) now outputs a string based on the shortest
1896 sequence of decimal digits that rounds to x. Previous behaviour was
1897 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001898 Another minor difference is that the new repr switches to
1899 exponential notation at 1e16 instead of the previous 1e17; this
1900 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001901
1902 There's a new sys attribute sys.float_repr_style, which takes
1903 the value 'short' to indicate that we're using short float repr,
1904 and 'legacy' if the short float repr isn't available for one
1905 reason or another.
1906
1907 The float repr change involves incorporating David Gay's 'perfect
1908 rounding' code into the Python core (it's in Python/dtoa.c). As a
1909 secondary consequence, all string-to-float and float-to-string
1910 conversions (including all float formatting operations) will be
1911 correctly rounded on these platforms.
1912
Georg Brandl442d3b32010-08-01 22:33:12 +00001913 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001914 this change does not apply.
1915
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001916- Issue #5759: float() didn't call __float__ on str subclasses.
1917
Georg Brandlabc38772009-04-12 15:51:51 +00001918- The string.maketrans() function is deprecated; there is a new static method
1919 maketrans() on the bytes and bytearray classes. This removes confusion about
1920 the types string.maketrans() is supposed to work with, and mirrors the
1921 methods available on the str class.
1922
R. David Murraydc6da8a2009-04-09 22:16:43 +00001923- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1924 its clarity and its speed.
1925
Matthias Klose091c7b12009-04-07 13:24:27 +00001926- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1927 to avoid compiler warnings.
1928
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001929- Issue #3739: The unicode-internal encoder now reports the number of characters
1930 consumed like any other encoder (instead of the number of bytes).

2072
Brett Cannon0759dd62009-04-01 18:13:07 +00002073- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2074
Georg Brandlab6f2f62009-03-31 04:16:10 +00002075- Fix a segfault when running test_exceptions with coverage, caused by
2076 insufficient checks in accessors of Exception.__context__.
2077
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002078- Issue #5604: non-ASCII characters in module name passed to
2079 imp.find_module() were converted to UTF-8 while the path is
2080 converted to the default filesystem encoding, causing nonsense.

2083
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002084- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2085 the end sys.path, for compatibility with the system install of Python.
2086
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002087- Issue #4688: Add a heuristic so that tuples and dicts containing only
2088 untrackable objects are not tracked by the garbage collector. This can
2089 reduce the size of collections and therefore the garbage collection overhead
2090 on long-running programs, depending on their particular use of datatypes.
2091
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002092- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

2104 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2105 and sizeof(Py_UNICODE) == 2.
2106
Eric Smith8ec90442009-03-14 12:29:34 +00002107- Issue #5237: Allow auto-numbered fields in str.format(). For

2109
Antoine Pitrou652e7072009-03-13 19:25:20 +00002110- Issue #5392: when a very low recursion limit was set, the interpreter would
2111 abort with a fatal error after the recursion limit was hit twice.
2112
Matthias Klose042f1332009-04-04 14:32:42 +00002113- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2159
Lars Gustäbel42e00912009-03-22 20:34:29 +00002160- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2161 forever on incomplete input. That caused tarfile.open() to hang when used
2162 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2163 partial bzip2 compressed data.
2164
Mark Dickinson79f52032009-03-17 23:12:51 +00002165- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00002213- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2214 it now forces its argument to double before testing for infinity.
2215
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002216- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2233 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2234 evaluation loop is compiled with a new dispatch mechanism which gives
2235 speedups of up to 20%, depending on the system, on various benchmarks.

2248 type to (void *).
2249
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002250- Issue #4935: The overflow checking code in the expandtabs() method common
2251 to str, bytes and bytearray could be optimized away by the compiler, letting
2252 the interpreter segfault instead of raising an error.
2253
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002254- Issue #3720: Fix a crash when an iterator modifies its class and removes its

2273 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2274

2277 previously buffered data). Patch by Dmitry Vasiliev.
2278
Antoine Pitrou05608432009-01-09 18:53:14 +00002279- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2280 flag to work properly. Furthermore, when specifying -u, the text stdout
2281 and stderr streams have line-by-line buffering enabled (the default being
2282 to buffer arbitrary chunks of data).
2283
Raymond Hettinger35631532009-01-09 03:58:09 +00002284- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2285 instead of ints (reducing its size from 4 to 8 times thereby reducing
2286 Python's overall memory).
2287
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002288- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2289 an existing .py counterpart, override the co_filename attributes of all
2290 code objects if the original filename is obsolete (which can happen if the
2291 file has been renamed, moved, or if it is accessed through different paths).
2292 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2293
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002294- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2295 one byte. Also fixes the meaning of len() so that it returns the number of
2296 items, rather than the size in bytes.
2297
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002298- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2299
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002300- Issue #4747: When the terminal does not use utf-8, executing a script with

2308
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002309- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2310 where the tp_hash and tp_dict slots are both NULL.
2311
Georg Brandlccc47b62008-12-28 11:44:14 +00002312- Issue #4759: None is now allowed as the first argument of

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002923- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2924 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2925 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2926 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002928- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002929 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002930 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002932- Issue #5083: New 'gui' resource for regrtest.
