383 Decimal operation raises multiple signals and more than one of those

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

417 witnessed in test_httpservers.
418
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000419- Issue #8524: When creating an SSL socket, the timeout value of the
420 original socket wasn't retained (instead, a socket with a positive timeout
421 would be turned into a non-blocking SSL socket).
422
Antoine Pitrouec146182010-04-24 21:30:20 +0000423- Issue #5103: SSL handshake would ignore the socket timeout and block
424 indefinitely if the other end didn't respond.
425
426- The do_handshake() method of SSL objects now adjusts the blocking mode of
427 the SSL structure if necessary (as other methods already do).

518 compared to other unix systems. In particular, os.getgroups() does

R. David Murray99352742009-05-07 18:24:38 +00001459 now it does. This also means getfp method now returns the real fp.

1498================================
1499
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001500*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001501
1502Core and Builtins
1503-----------------
1504
Mark Dickinson865e01a2009-05-07 16:37:01 +00001505- Issue #5914: Add new C API function PyOS_string_to_double, and
1506 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1507
Eric Smith741191f2009-05-06 13:08:15 +00001508- Issue #3382: float.__format__, complex.__format__, and %-formatting
1509 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1510 affects nan -> NAN and inf -> INF.
1511
Mark Hammond5a607a32009-05-06 08:04:54 +00001512- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1513 in all operations, including splitdrive, split, etc. splitunc() now issues
1514 a PendingDeprecation warning.
1515
Eric Smith63376222009-05-05 14:04:18 +00001516- Issue #5920: For float.__format__, change the behavior with the
1517 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1518 to be like 'g' but with at least one decimal point and with a
1519 default precision of 12. Previously, the behavior the same but with
1520 a default precision of 6. This more closely matches str(), and
1521 reduces surprises when adding alignment flags to the empty
1522 presentation type. This also affects the new complex.__format__ in
1523 the same way.
1524
Martin v. Löwis011e8422009-05-05 04:43:17 +00001525- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1526
R. David Murrayb18500d2009-05-04 22:59:07 +00001527- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1528 shadowed by classtype's, even if it was None. property now
1529 inserts the __doc__ into the subclass instance __dict__.
1530
Antoine Pitrou244651a2009-05-04 18:56:13 +00001531- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1532 sequences. Patch by Nick Barnes and Victor Stinner.
1533
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001534- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001535
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001536- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1537 received a new method, detach(). detach() disconnects the underlying stream
1538 from the buffer or text IO and returns it.
1539
Mark Dickinson33841c32009-05-01 15:37:04 +00001540- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1541 floats with absolute value over 1e50. Also remove length
1542 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1543 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001544
Eric Smith741191f2009-05-06 13:08:15 +00001545- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001546 format(complex(1, 2./3), '.5') now produces a sensible result.
1547
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001548- Issue #5864: Fix empty format code formatting for floats so that it
1549 never gives more than the requested number of significant digits.
1550
Eric Smith6dc46f52009-04-27 20:39:49 +00001551- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1552 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1553
Eric Smithcc32a112009-04-26 21:35:14 +00001554- Issue #5835: Deprecate PyOS_ascii_formatd.
1555
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001556- Issue #4971: Fix titlecase for characters that are their own
1557 titlecase, but not their own uppercase.
1558
Benjamin Peterson193152c2009-04-25 01:08:45 +00001559- Issue #5283: Setting __class__ in __del__ caused a segfault.
1560
Mark Dickinsonad476da2009-04-23 19:14:16 +00001561- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1562 z involves nans, infs or negative zeros.
1563
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001564- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001565
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001566- Issue #1869 (and many duplicates): make round(x, n) correctly
1567 rounded for a float x, by using the decimal <-> binary conversions
1568 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1569 consistently agrees with format(x, '.2f').
1570
Benjamin Petersonae937c02009-04-18 20:54:08 +00001571- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1572 some builtin types.
1573
Eric Smith0923d1d2009-04-16 20:16:10 +00001574- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1575
Eric Smith35e84722009-04-16 20:21:28 +00001576- Issue #5515: str.format() type 'n' combined with commas and leading
1577 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001578
1579- Implement PEP 378, Format Specifier for Thousands Separator, for
1580 floats.
1581
Mark Dickinson3370cce2009-04-17 22:40:53 +00001582- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001583 1e11, not 1e12. This avoids printing 13 significant digits in
1584 situations where only 12 of them are correct. Example problem
1585 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1586 long time.)
1587
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001588- Issue #1580: On most platforms, use a 'short' float repr: for a
1589 finite float x, repr(x) now outputs a string based on the shortest
1590 sequence of decimal digits that rounds to x. Previous behaviour was
1591 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001592 Another minor difference is that the new repr switches to
1593 exponential notation at 1e16 instead of the previous 1e17; this
1594 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001595
1596 There's a new sys attribute sys.float_repr_style, which takes
1597 the value 'short' to indicate that we're using short float repr,
1598 and 'legacy' if the short float repr isn't available for one
1599 reason or another.
1600
1601 The float repr change involves incorporating David Gay's 'perfect
1602 rounding' code into the Python core (it's in Python/dtoa.c). As a
1603 secondary consequence, all string-to-float and float-to-string
1604 conversions (including all float formatting operations) will be
1605 correctly rounded on these platforms.
1606
Georg Brandl442d3b32010-08-01 22:33:12 +00001607 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001608 this change does not apply.
1609
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001610- Issue #5759: float() didn't call __float__ on str subclasses.
1611
Georg Brandlabc38772009-04-12 15:51:51 +00001612- The string.maketrans() function is deprecated; there is a new static method
1613 maketrans() on the bytes and bytearray classes. This removes confusion about
1614 the types string.maketrans() is supposed to work with, and mirrors the
1615 methods available on the str class.
1616
R. David Murraydc6da8a2009-04-09 22:16:43 +00001617- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1618 its clarity and its speed.
1619
Matthias Klose091c7b12009-04-07 13:24:27 +00001620- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1621 to avoid compiler warnings.
1622
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001623- Issue #3739: The unicode-internal encoder now reports the number of characters
1624 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001759- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1760
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001761- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1762 byte, and the 'C' code only accepts a unicode character.
1763
Georg Brandl406b3d82009-04-11 21:24:37 +00001764- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1765 when hitting the recursion limit under certain circumstances.
1766
Brett Cannon0759dd62009-04-01 18:13:07 +00001767- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1768
Georg Brandlab6f2f62009-03-31 04:16:10 +00001769- Fix a segfault when running test_exceptions with coverage, caused by
1770 insufficient checks in accessors of Exception.__context__.
1771
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001772- Issue #5604: non-ASCII characters in module name passed to
1773 imp.find_module() were converted to UTF-8 while the path is
1774 converted to the default filesystem encoding, causing nonsense.
1775
Benjamin Peterson09832742009-03-26 17:15:46 +00001776- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001778- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1779 the end sys.path, for compatibility with the system install of Python.
1780
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001781- Issue #4688: Add a heuristic so that tuples and dicts containing only
1782 untrackable objects are not tracked by the garbage collector. This can
1783 reduce the size of collections and therefore the garbage collection overhead
1784 on long-running programs, depending on their particular use of datatypes.
1785
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001786- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1789
Mark Dickinsonbd792642009-03-18 20:06:12 +00001790- Issue #4258: Make it possible to use base 2**30 instead of base
1791 2**15 for the internal representation of integers, for performance
1792 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1793 --enable-big-digits option to configure, which overrides the
1794 default. Add sys.int_info structseq to provide information about
1795 the internal format.
1796
Mark Dickinson081dfee2009-03-18 14:47:41 +00001797- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1798 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1799 and sizeof(Py_UNICODE) == 2.
1800
Eric Smith8ec90442009-03-14 12:29:34 +00001801- Issue #5237: Allow auto-numbered fields in str.format(). For

1803
Antoine Pitrou652e7072009-03-13 19:25:20 +00001804- Issue #5392: when a very low recursion limit was set, the interpreter would
1805 abort with a fatal error after the recursion limit was hit twice.
1806
Matthias Klose042f1332009-04-04 14:32:42 +00001807- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Brett Cannon7f6b4f82009-03-30 21:30:26 +00001839- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1840 bytes already but the failure was non-obvious.
1841
Jesse Noller7af4ef82009-03-30 16:47:15 +00001842- Issue #5177: Multiprocessing's SocketListener class now uses

1853
Lars Gustäbel42e00912009-03-22 20:34:29 +00001854- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1855 forever on incomplete input. That caused tarfile.open() to hang when used
1856 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1857 partial bzip2 compressed data.
1858
Mark Dickinson79f52032009-03-17 23:12:51 +00001859- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001878 struct.error instead of returning b'\xff\xff\xff\xff'. The
1879 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1899 contained non ascii character on windows.
1900
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001901- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1902 source has already been decoded into str.
1903
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001904- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1905 rotating the object pointer by 4 bits to the right.
1906
Mark Dickinson87ec0852009-02-09 17:15:59 +00001907- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1908 it now forces its argument to double before testing for infinity.
1909
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001910- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1911 returns a non-number type.
1912
Benjamin Peterson87618552009-02-08 15:00:52 +00001913- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001919
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001920- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001921 were suppressing all exceptions. These include list() and bytearray().
1922
Mark Dickinson1124e712009-01-28 21:25:58 +00001923- Issue #4707: round(x, n) now returns an integer if x is an integer.
1924 Previously it returned a float.
1925
Antoine Pitroub52ec782009-01-25 16:34:23 +00001926- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1927 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1928 evaluation loop is compiled with a new dispatch mechanism which gives
1929 speedups of up to 20%, depending on the system, on various benchmarks.
1930
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001931- Issue #4874: Most builtin decoders now reject unicode input.

1939 optional module state data.
1940
Mark Dickinson8055afd2009-01-17 10:04:45 +00001941- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1942 type to (void *).
1943
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001944- Issue #4935: The overflow checking code in the expandtabs() method common
1945 to str, bytes and bytearray could be optimized away by the compiler, letting
1946 the interpreter segfault instead of raising an error.
1947
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001948- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1949 __next__ method.
1950
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001951- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1960 common cases are optimized thanks to a dedicated fast path and a moderate
1961 amount of loop unrolling.
1962
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001963- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1964 collecting the oldest generation) so that allocating lots of objects without
1965 destroying them does not show quadratic performance. Based on a proposal by
1966 Martin von Löwis at
1967 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1968
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001969- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001970 having been closed (for instance, a read() call could return some
1971 previously buffered data). Patch by Dmitry Vasiliev.
1972
Antoine Pitrou05608432009-01-09 18:53:14 +00001973- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1974 flag to work properly. Furthermore, when specifying -u, the text stdout
1975 and stderr streams have line-by-line buffering enabled (the default being
1976 to buffer arbitrary chunks of data).
1977
Raymond Hettinger35631532009-01-09 03:58:09 +00001978- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1979 instead of ints (reducing its size from 4 to 8 times thereby reducing
1980 Python's overall memory).
1981
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001982- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1983 an existing .py counterpart, override the co_filename attributes of all
1984 code objects if the original filename is obsolete (which can happen if the
1985 file has been renamed, moved, or if it is accessed through different paths).
1986 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1987
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001988- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1989 one byte. Also fixes the meaning of len() so that it returns the number of
1990 items, rather than the size in bytes.
1991
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001992- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1993
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001994- Issue #4747: When the terminal does not use utf-8, executing a script with
1995 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1996
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001997- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Antoine Pitrou7ddda782009-01-01 15:35:33 +00002000- Issue #3680: Reference cycles created through a dict, set or deque iterator
2001 did not get collected.
2002
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002003- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2004 where the tp_hash and tp_dict slots are both NULL.
2005
Georg Brandlccc47b62008-12-28 11:44:14 +00002006- Issue #4759: None is now allowed as the first argument of
2007 bytearray.translate(). It was always allowed for bytes.translate().
2008
Skip Montanaro80072cb2008-12-23 03:51:14 +00002009- Added test case to ensure attempts to read from a file opened for writing
2010 fail.

2019 unreachable. Original patch by Neil Schemenauer.
2020
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002021- Issue #3439: Add a bit_length method to int.
2022
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002023- Issue #2173: When getting device encoding, check that return value of
2024 nl_langinfo is not the empty string. This was causing silent build
2025 failures on OS X.
2026
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002027- Issue #4597: Fixed several opcodes that weren't always propagating
2028 exceptions.
2029

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002617- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2618 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2619 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2620 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002622- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002623 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002624 from test support, which does the conversion.
