380 Decimal operation raises multiple signals and more than one of those
381 signals is trapped, the specification determines the order in which
382 the signals should be handled. In many cases this order wasn't
383 being followed, leading to the wrong Python exception being raised.

414 witnessed in test_httpservers.
415
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000416- Issue #8524: When creating an SSL socket, the timeout value of the
417 original socket wasn't retained (instead, a socket with a positive timeout
418 would be turned into a non-blocking SSL socket).
419
Antoine Pitrouec146182010-04-24 21:30:20 +0000420- Issue #5103: SSL handshake would ignore the socket timeout and block
421 indefinitely if the other end didn't respond.
422
423- The do_handshake() method of SSL objects now adjusts the blocking mode of
424 the SSL structure if necessary (as other methods already do).
425
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000426- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
427 a non-infinite timeout. Also make that method friendlier with applications
428 wanting to continue using the socket in clear-text mode, by disabling
429 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

462
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000463- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

465 Initial patch by Bertrand Janin.
466
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000467- Issue #7512: shutil.copystat() could raise an OSError when the filesystem

472 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
473 reads and writes are always retried by OpenSSL itself.

512 compared to other unix systems. In particular, os.getgroups() does
513 not reflect any changes made using os.setgroups() but basicly always
514 returns the same information as the id command.
515
516 os.getgroups() can now return more than 16 groups on MacOSX.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001495
1496Core and Builtins
1497-----------------
1498
Mark Dickinson865e01a2009-05-07 16:37:01 +00001499- Issue #5914: Add new C API function PyOS_string_to_double, and
1500 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1501
Eric Smith741191f2009-05-06 13:08:15 +00001502- Issue #3382: float.__format__, complex.__format__, and %-formatting
1503 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1504 affects nan -> NAN and inf -> INF.
1505
Mark Hammond5a607a32009-05-06 08:04:54 +00001506- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1507 in all operations, including splitdrive, split, etc. splitunc() now issues
1508 a PendingDeprecation warning.
1509
Eric Smith63376222009-05-05 14:04:18 +00001510- Issue #5920: For float.__format__, change the behavior with the
1511 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1512 to be like 'g' but with at least one decimal point and with a
1513 default precision of 12. Previously, the behavior the same but with
1514 a default precision of 6. This more closely matches str(), and
1515 reduces surprises when adding alignment flags to the empty
1516 presentation type. This also affects the new complex.__format__ in
1517 the same way.
1518
Martin v. Löwis011e8422009-05-05 04:43:17 +00001519- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1520
R. David Murrayb18500d2009-05-04 22:59:07 +00001521- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1522 shadowed by classtype's, even if it was None. property now
1523 inserts the __doc__ into the subclass instance __dict__.
1524
Antoine Pitrou244651a2009-05-04 18:56:13 +00001525- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1526 sequences. Patch by Nick Barnes and Victor Stinner.
1527
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001528- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001529
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001530- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1531 received a new method, detach(). detach() disconnects the underlying stream
1532 from the buffer or text IO and returns it.
1533
Mark Dickinson33841c32009-05-01 15:37:04 +00001534- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1535 floats with absolute value over 1e50. Also remove length
1536 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1537 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001538
Eric Smith741191f2009-05-06 13:08:15 +00001539- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001540 format(complex(1, 2./3), '.5') now produces a sensible result.
1541
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001542- Issue #5864: Fix empty format code formatting for floats so that it
1543 never gives more than the requested number of significant digits.
1544
Eric Smith6dc46f52009-04-27 20:39:49 +00001545- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1546 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1547
Eric Smithcc32a112009-04-26 21:35:14 +00001548- Issue #5835: Deprecate PyOS_ascii_formatd.
1549
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001550- Issue #4971: Fix titlecase for characters that are their own
1551 titlecase, but not their own uppercase.
1552
Benjamin Peterson193152c2009-04-25 01:08:45 +00001553- Issue #5283: Setting __class__ in __del__ caused a segfault.
1554
Mark Dickinsonad476da2009-04-23 19:14:16 +00001555- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1556 z involves nans, infs or negative zeros.
1557
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001558- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001559
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001560- Issue #1869 (and many duplicates): make round(x, n) correctly
1561 rounded for a float x, by using the decimal <-> binary conversions
1562 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1563 consistently agrees with format(x, '.2f').
1564
Benjamin Petersonae937c02009-04-18 20:54:08 +00001565- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1566 some builtin types.
1567
Eric Smith0923d1d2009-04-16 20:16:10 +00001568- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1569
Eric Smith35e84722009-04-16 20:21:28 +00001570- Issue #5515: str.format() type 'n' combined with commas and leading
1571 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001572
1573- Implement PEP 378, Format Specifier for Thousands Separator, for
1574 floats.
1575
Mark Dickinson3370cce2009-04-17 22:40:53 +00001576- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001577 1e11, not 1e12. This avoids printing 13 significant digits in
1578 situations where only 12 of them are correct. Example problem
1579 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1580 long time.)
1581
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001582- Issue #1580: On most platforms, use a 'short' float repr: for a
1583 finite float x, repr(x) now outputs a string based on the shortest
1584 sequence of decimal digits that rounds to x. Previous behaviour was
1585 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001586 Another minor difference is that the new repr switches to
1587 exponential notation at 1e16 instead of the previous 1e17; this
1588 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001589
1590 There's a new sys attribute sys.float_repr_style, which takes
1591 the value 'short' to indicate that we're using short float repr,
1592 and 'legacy' if the short float repr isn't available for one
1593 reason or another.
1594
1595 The float repr change involves incorporating David Gay's 'perfect
1596 rounding' code into the Python core (it's in Python/dtoa.c). As a
1597 secondary consequence, all string-to-float and float-to-string
1598 conversions (including all float formatting operations) will be
1599 correctly rounded on these platforms.
1600
Georg Brandl442d3b32010-08-01 22:33:12 +00001601 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001602 this change does not apply.
1603
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001604- Issue #5759: float() didn't call __float__ on str subclasses.
1605
Georg Brandlabc38772009-04-12 15:51:51 +00001606- The string.maketrans() function is deprecated; there is a new static method
1607 maketrans() on the bytes and bytearray classes. This removes confusion about
1608 the types string.maketrans() is supposed to work with, and mirrors the
1609 methods available on the str class.
1610
R. David Murraydc6da8a2009-04-09 22:16:43 +00001611- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1612 its clarity and its speed.
1613
Matthias Klose091c7b12009-04-07 13:24:27 +00001614- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1615 to avoid compiler warnings.
1616
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001617- Issue #3739: The unicode-internal encoder now reports the number of characters
1618 consumed like any other encoder (instead of the number of bytes).

1756 byte, and the 'C' code only accepts a unicode character.
1757
Georg Brandl406b3d82009-04-11 21:24:37 +00001758- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1759 when hitting the recursion limit under certain circumstances.
1760
Brett Cannon0759dd62009-04-01 18:13:07 +00001761- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1762
Georg Brandlab6f2f62009-03-31 04:16:10 +00001763- Fix a segfault when running test_exceptions with coverage, caused by
1764 insufficient checks in accessors of Exception.__context__.
1765
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001766- Issue #5604: non-ASCII characters in module name passed to
1767 imp.find_module() were converted to UTF-8 while the path is
1768 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001772- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1773 the end sys.path, for compatibility with the system install of Python.
1774
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001775- Issue #4688: Add a heuristic so that tuples and dicts containing only
1776 untrackable objects are not tracked by the garbage collector. This can
1777 reduce the size of collections and therefore the garbage collection overhead
1778 on long-running programs, depending on their particular use of datatypes.
1779
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001780- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1783
Mark Dickinsonbd792642009-03-18 20:06:12 +00001784- Issue #4258: Make it possible to use base 2**30 instead of base
1785 2**15 for the internal representation of integers, for performance
1786 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1787 --enable-big-digits option to configure, which overrides the
1788 default. Add sys.int_info structseq to provide information about
1789 the internal format.
1790
Mark Dickinson081dfee2009-03-18 14:47:41 +00001791- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1792 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1793 and sizeof(Py_UNICODE) == 2.
1794
Eric Smith8ec90442009-03-14 12:29:34 +00001795- Issue #5237: Allow auto-numbered fields in str.format(). For

1797
Antoine Pitrou652e7072009-03-13 19:25:20 +00001798- Issue #5392: when a very low recursion limit was set, the interpreter would
1799 abort with a fatal error after the recursion limit was hit twice.
1800
Matthias Klose042f1332009-04-04 14:32:42 +00001801- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1847
Lars Gustäbel42e00912009-03-22 20:34:29 +00001848- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1849 forever on incomplete input. That caused tarfile.open() to hang when used
1850 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinson87ec0852009-02-09 17:15:59 +00001901- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1902 it now forces its argument to double before testing for infinity.
1903
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001904- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1905 returns a non-number type.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001914- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001915 were suppressing all exceptions. These include list() and bytearray().
1916
Mark Dickinson1124e712009-01-28 21:25:58 +00001917- Issue #4707: round(x, n) now returns an integer if x is an integer.
1918 Previously it returned a float.
1919
Antoine Pitroub52ec782009-01-25 16:34:23 +00001920- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1921 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1922 evaluation loop is compiled with a new dispatch mechanism which gives
1923 speedups of up to 20%, depending on the system, on various benchmarks.
1924
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001925- Issue #4874: Most builtin decoders now reject unicode input.

1933 optional module state data.
1934
Mark Dickinson8055afd2009-01-17 10:04:45 +00001935- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1936 type to (void *).
1937
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001938- Issue #4935: The overflow checking code in the expandtabs() method common
1939 to str, bytes and bytearray could be optimized away by the compiler, letting
1940 the interpreter segfault instead of raising an error.
1941
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001942- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1943 __next__ method.
1944
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001945- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1954 common cases are optimized thanks to a dedicated fast path and a moderate
1955 amount of loop unrolling.
1956
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001957- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1958 collecting the oldest generation) so that allocating lots of objects without
1959 destroying them does not show quadratic performance. Based on a proposal by
1960 Martin von Löwis at
1961 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1962
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001963- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001964 having been closed (for instance, a read() call could return some
1965 previously buffered data). Patch by Dmitry Vasiliev.
1966
Antoine Pitrou05608432009-01-09 18:53:14 +00001967- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1968 flag to work properly. Furthermore, when specifying -u, the text stdout
1969 and stderr streams have line-by-line buffering enabled (the default being
1970 to buffer arbitrary chunks of data).
1971
Raymond Hettinger35631532009-01-09 03:58:09 +00001972- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1973 instead of ints (reducing its size from 4 to 8 times thereby reducing
1974 Python's overall memory).
1975
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001976- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1977 an existing .py counterpart, override the co_filename attributes of all
1978 code objects if the original filename is obsolete (which can happen if the
1979 file has been renamed, moved, or if it is accessed through different paths).
1980 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1981
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001982- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1983 one byte. Also fixes the meaning of len() so that it returns the number of
1984 items, rather than the size in bytes.
1985
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001986- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1987
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001988- Issue #4747: When the terminal does not use utf-8, executing a script with
1989 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1990

Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001993
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001994- Issue #3680: Reference cycles created through a dict, set or deque iterator
1995 did not get collected.
1996
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001997- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1998 where the tp_hash and tp_dict slots are both NULL.
1999
Georg Brandlccc47b62008-12-28 11:44:14 +00002000- Issue #4759: None is now allowed as the first argument of
2001 bytearray.translate(). It was always allowed for bytes.translate().
2002
Skip Montanaro80072cb2008-12-23 03:51:14 +00002003- Added test case to ensure attempts to read from a file opened for writing
2004 fail.

2010
Antoine Pitrou621601a2008-12-17 23:18:19 +00002011- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2012 print elapsed times, not only when some objects are uncollectable /
2013 unreachable. Original patch by Neil Schemenauer.
2014
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002015- Issue #3439: Add a bit_length method to int.
2016
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002017- Issue #2173: When getting device encoding, check that return value of
2018 nl_langinfo is not the empty string. This was causing silent build
2019 failures on OS X.
2020
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002021- Issue #4597: Fixed several opcodes that weren't always propagating
2022 exceptions.
2023
2024- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002025 context manager returns a value that cannot be converted to a bool.
2026
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002027- Issue #4445: Replace "sizeof(PyBytesObject)" with
2028 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

2030 (on average) per allocation of a bytes instance.
2031
Christian Heimesa872de52008-12-05 08:26:55 +00002032- Issue #4533: File read operation was dreadfully slow due to a slowly

2034 Python 2.x.
2035
Antoine Pitrou5504e892008-12-06 21:27:53 +00002036- Issue #4509: Various issues surrounding resize of bytearray objects to

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002611- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2612 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2613 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2614 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002616- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002617 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002618 from test support, which does the conversion.
