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

361 being followed, leading to the wrong Python exception being raised.

392 witnessed in test_httpservers.
393
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000394- Issue #8524: When creating an SSL socket, the timeout value of the
395 original socket wasn't retained (instead, a socket with a positive timeout
396 would be turned into a non-blocking SSL socket).
397
Antoine Pitrouec146182010-04-24 21:30:20 +0000398- Issue #5103: SSL handshake would ignore the socket timeout and block
399 indefinitely if the other end didn't respond.
400
401- The do_handshake() method of SSL objects now adjusts the blocking mode of
402 the SSL structure if necessary (as other methods already do).

Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000404- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
405 a non-infinite timeout. Also make that method friendlier with applications
406 wanting to continue using the socket in clear-text mode, by disabling
407 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001463- Issue #5914: Add new C API function PyOS_string_to_double, and
1464 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1465
Eric Smith741191f2009-05-06 13:08:15 +00001466- Issue #3382: float.__format__, complex.__format__, and %-formatting
1467 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1468 affects nan -> NAN and inf -> INF.
1469
Mark Hammond5a607a32009-05-06 08:04:54 +00001470- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1471 in all operations, including splitdrive, split, etc. splitunc() now issues
1472 a PendingDeprecation warning.
1473
Eric Smith63376222009-05-05 14:04:18 +00001474- Issue #5920: For float.__format__, change the behavior with the
1475 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1476 to be like 'g' but with at least one decimal point and with a
1477 default precision of 12. Previously, the behavior the same but with
1478 a default precision of 6. This more closely matches str(), and
1479 reduces surprises when adding alignment flags to the empty
1480 presentation type. This also affects the new complex.__format__ in
1481 the same way.
1482
Martin v. Löwis011e8422009-05-05 04:43:17 +00001483- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1484
R. David Murrayb18500d2009-05-04 22:59:07 +00001485- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1486 shadowed by classtype's, even if it was None. property now
1487 inserts the __doc__ into the subclass instance __dict__.
1488
Antoine Pitrou244651a2009-05-04 18:56:13 +00001489- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1490 sequences. Patch by Nick Barnes and Victor Stinner.
1491
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001492- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001493
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001494- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1495 received a new method, detach(). detach() disconnects the underlying stream
1496 from the buffer or text IO and returns it.
1497
Mark Dickinson33841c32009-05-01 15:37:04 +00001498- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1499 floats with absolute value over 1e50. Also remove length
1500 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1501 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001502
Eric Smith741191f2009-05-06 13:08:15 +00001503- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001504 format(complex(1, 2./3), '.5') now produces a sensible result.
1505
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001506- Issue #5864: Fix empty format code formatting for floats so that it
1507 never gives more than the requested number of significant digits.
1508
Eric Smith6dc46f52009-04-27 20:39:49 +00001509- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1510 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1511
Eric Smithcc32a112009-04-26 21:35:14 +00001512- Issue #5835: Deprecate PyOS_ascii_formatd.
1513
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001514- Issue #4971: Fix titlecase for characters that are their own
1515 titlecase, but not their own uppercase.
1516
Benjamin Peterson193152c2009-04-25 01:08:45 +00001517- Issue #5283: Setting __class__ in __del__ caused a segfault.
1518
Mark Dickinsonad476da2009-04-23 19:14:16 +00001519- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1520 z involves nans, infs or negative zeros.
1521
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001522- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001523
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001524- Issue #1869 (and many duplicates): make round(x, n) correctly
1525 rounded for a float x, by using the decimal <-> binary conversions
1526 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1527 consistently agrees with format(x, '.2f').
1528
Benjamin Petersonae937c02009-04-18 20:54:08 +00001529- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1530 some builtin types.
1531
Eric Smith0923d1d2009-04-16 20:16:10 +00001532- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1533
Eric Smith35e84722009-04-16 20:21:28 +00001534- Issue #5515: str.format() type 'n' combined with commas and leading
1535 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001536
1537- Implement PEP 378, Format Specifier for Thousands Separator, for
1538 floats.
1539
Mark Dickinson3370cce2009-04-17 22:40:53 +00001540- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001541 1e11, not 1e12. This avoids printing 13 significant digits in
1542 situations where only 12 of them are correct. Example problem
1543 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1544 long time.)
1545
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001546- Issue #1580: On most platforms, use a 'short' float repr: for a
1547 finite float x, repr(x) now outputs a string based on the shortest
1548 sequence of decimal digits that rounds to x. Previous behaviour was
1549 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001550 Another minor difference is that the new repr switches to
1551 exponential notation at 1e16 instead of the previous 1e17; this
1552 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001553
1554 There's a new sys attribute sys.float_repr_style, which takes
1555 the value 'short' to indicate that we're using short float repr,
1556 and 'legacy' if the short float repr isn't available for one
1557 reason or another.
1558
1559 The float repr change involves incorporating David Gay's 'perfect
1560 rounding' code into the Python core (it's in Python/dtoa.c). As a
1561 secondary consequence, all string-to-float and float-to-string
1562 conversions (including all float formatting operations) will be
1563 correctly rounded on these platforms.
1564
Georg Brandl442d3b32010-08-01 22:33:12 +00001565 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001566 this change does not apply.
1567
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001568- Issue #5759: float() didn't call __float__ on str subclasses.
1569
Georg Brandlabc38772009-04-12 15:51:51 +00001570- The string.maketrans() function is deprecated; there is a new static method
1571 maketrans() on the bytes and bytearray classes. This removes confusion about
1572 the types string.maketrans() is supposed to work with, and mirrors the
1573 methods available on the str class.
1574
R. David Murraydc6da8a2009-04-09 22:16:43 +00001575- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1576 its clarity and its speed.
1577
Matthias Klose091c7b12009-04-07 13:24:27 +00001578- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1579 to avoid compiler warnings.
1580
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001581- Issue #3739: The unicode-internal encoder now reports the number of characters
1582 consumed like any other encoder (instead of the number of bytes).

1593 specific Python version.
1594
Raymond Hettingereb816952009-05-29 01:22:18 +00001595- Issue #5150: IDLE's format menu now has an option to strip trailing
1596 whitespace.
1597
Vinay Sajipaffbd872009-06-11 10:11:47 +00001598- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +00001599 the right type checkings anymore.

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001717- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1718
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001719- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1720 byte, and the 'C' code only accepts a unicode character.
1721
Georg Brandl406b3d82009-04-11 21:24:37 +00001722- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

1728 insufficient checks in accessors of Exception.__context__.
1729
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001730- Issue #5604: non-ASCII characters in module name passed to
1731 imp.find_module() were converted to UTF-8 while the path is
1732 converted to the default filesystem encoding, causing nonsense.
1733
Benjamin Peterson09832742009-03-26 17:15:46 +00001734- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001736- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1737 the end sys.path, for compatibility with the system install of Python.
1738
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001739- Issue #4688: Add a heuristic so that tuples and dicts containing only
1740 untrackable objects are not tracked by the garbage collector. This can
1741 reduce the size of collections and therefore the garbage collection overhead
1742 on long-running programs, depending on their particular use of datatypes.
1743
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001744- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1749 2**15 for the internal representation of integers, for performance
1750 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1751 --enable-big-digits option to configure, which overrides the
1752 default. Add sys.int_info structseq to provide information about
1753 the internal format.
1754
Mark Dickinson081dfee2009-03-18 14:47:41 +00001755- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1756 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1757 and sizeof(Py_UNICODE) == 2.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001865- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1866 it now forces its argument to double before testing for infinity.
1867
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001868- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001877
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001878- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001879 were suppressing all exceptions. These include list() and bytearray().

1883
Antoine Pitroub52ec782009-01-25 16:34:23 +00001884- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1885 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1886 evaluation loop is compiled with a new dispatch mechanism which gives
1887 speedups of up to 20%, depending on the system, on various benchmarks.
1888

1895
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001896- Issue #4838: When a module is deallocated, free the memory backing the
1897 optional module state data.
1898
Mark Dickinson8055afd2009-01-17 10:04:45 +00001899- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1900 type to (void *).
1901
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001902- Issue #4935: The overflow checking code in the expandtabs() method common
1903 to str, bytes and bytearray could be optimized away by the compiler, letting
1904 the interpreter segfault instead of raising an error.
1905
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001906- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1907 __next__ method.
1908
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001909- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1910 function no longer attempt to call the __long__ slot to convert an object
1911 to an integer. Only the __int__ and __trunc__ slots are examined.
1912
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001913- Issue #4893: Use NT threading on CE.
1914

1916
Antoine Pitrouab868312009-01-10 15:40:25 +00001917- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1918 common cases are optimized thanks to a dedicated fast path and a moderate
1919 amount of loop unrolling.
1920
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001921- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1922 collecting the oldest generation) so that allocating lots of objects without
1923 destroying them does not show quadratic performance. Based on a proposal by
1924 Martin von Löwis at
1925 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1926
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001927- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001928 having been closed (for instance, a read() call could return some
1929 previously buffered data). Patch by Dmitry Vasiliev.
1930
Antoine Pitrou05608432009-01-09 18:53:14 +00001931- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1932 flag to work properly. Furthermore, when specifying -u, the text stdout
1933 and stderr streams have line-by-line buffering enabled (the default being
1934 to buffer arbitrary chunks of data).
1935
Raymond Hettinger35631532009-01-09 03:58:09 +00001936- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1937 instead of ints (reducing its size from 4 to 8 times thereby reducing
1938 Python's overall memory).
1939
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001940- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1941 an existing .py counterpart, override the co_filename attributes of all
1942 code objects if the original filename is obsolete (which can happen if the
1943 file has been renamed, moved, or if it is accessed through different paths).
1944 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1945
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001946- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1947 one byte. Also fixes the meaning of len() so that it returns the number of
1948 items, rather than the size in bytes.
1949
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001950- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1951
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001952- Issue #4747: When the terminal does not use utf-8, executing a script with
1953 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1954
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001955- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001956 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001957
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001958- Issue #3680: Reference cycles created through a dict, set or deque iterator
1959 did not get collected.
1960
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001961- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1962 where the tp_hash and tp_dict slots are both NULL.
1963
Georg Brandlccc47b62008-12-28 11:44:14 +00001964- Issue #4759: None is now allowed as the first argument of
1965 bytearray.translate(). It was always allowed for bytes.translate().
1966
Skip Montanaro80072cb2008-12-23 03:51:14 +00001967- Added test case to ensure attempts to read from a file opened for writing
1968 fail.
1969

1973 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1974
Antoine Pitrou621601a2008-12-17 23:18:19 +00001975- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1976 print elapsed times, not only when some objects are uncollectable /
1977 unreachable. Original patch by Neil Schemenauer.
1978
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001979- Issue #3439: Add a bit_length method to int.
1980
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001981- Issue #2173: When getting device encoding, check that return value of
1982 nl_langinfo is not the empty string. This was causing silent build
1983 failures on OS X.
1984
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001985- Issue #4597: Fixed several opcodes that weren't always propagating
1986 exceptions.
1987
1988- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001989 context manager returns a value that cannot be converted to a bool.
1990
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001991- Issue #4445: Replace "sizeof(PyBytesObject)" with
1992 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1993 bytes instances. On a typical machine this saves 3 bytes of memory
1994 (on average) per allocation of a bytes instance.
1995
Christian Heimesa872de52008-12-05 08:26:55 +00001996- Issue #4533: File read operation was dreadfully slow due to a slowly
1997 growing read buffer. Fixed by using the same growth rate algorithm as
1998 Python 2.x.
1999
Antoine Pitrou5504e892008-12-06 21:27:53 +00002000- Issue #4509: Various issues surrounding resize of bytearray objects to
2001 which there are buffer exports (e.g. memoryview instances).
2002
Georg Brandlf9734072008-12-07 15:30:06 +00002003- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2004 method on file objects with closefd=False. The file descriptor is still
2005 kept open but the file object behaves like a closed file. The ``FileIO``
2006 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002007
Antoine Pitroubc420402008-12-07 20:14:49 +00002008- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002015- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2016 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2017 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2018 of using the replace error handler in PyUnicode_DecodeUTF8().
