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.
384
Antoine Pitroufaf90072010-05-03 16:58:19 +0000385- Issue #7865: The close() method of :mod:`io` objects should not swallow

413 event loop started running. This also fixes the occasional freezes
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.

440 the _ssl extension, such that verification of some SSL certificates
441 doesn't fail because of an "unknown algorithm".
442

459 Python 2.x and 3.0

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

469 now silenced.
470
Antoine Pitroued6c8932010-03-26 19:38:11 +0000471- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
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.

515 compared to other unix systems. In particular, os.getgroups() does
516 not reflect any changes made using os.setgroups() but basicly always
517 returns the same information as the id command.

R. David Murray99352742009-05-07 18:24:38 +00001456 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001498
1499Core and Builtins
1500-----------------
1501
Mark Dickinson865e01a2009-05-07 16:37:01 +00001502- Issue #5914: Add new C API function PyOS_string_to_double, and
1503 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1504
Eric Smith741191f2009-05-06 13:08:15 +00001505- Issue #3382: float.__format__, complex.__format__, and %-formatting
1506 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1507 affects nan -> NAN and inf -> INF.
1508
Mark Hammond5a607a32009-05-06 08:04:54 +00001509- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1510 in all operations, including splitdrive, split, etc. splitunc() now issues
1511 a PendingDeprecation warning.
1512
Eric Smith63376222009-05-05 14:04:18 +00001513- Issue #5920: For float.__format__, change the behavior with the
1514 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1515 to be like 'g' but with at least one decimal point and with a
1516 default precision of 12. Previously, the behavior the same but with
1517 a default precision of 6. This more closely matches str(), and
1518 reduces surprises when adding alignment flags to the empty
1519 presentation type. This also affects the new complex.__format__ in
1520 the same way.
1521
Martin v. Löwis011e8422009-05-05 04:43:17 +00001522- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1523
R. David Murrayb18500d2009-05-04 22:59:07 +00001524- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1525 shadowed by classtype's, even if it was None. property now
1526 inserts the __doc__ into the subclass instance __dict__.
1527
Antoine Pitrou244651a2009-05-04 18:56:13 +00001528- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1529 sequences. Patch by Nick Barnes and Victor Stinner.
1530
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001531- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001532
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001533- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1534 received a new method, detach(). detach() disconnects the underlying stream
1535 from the buffer or text IO and returns it.
1536
Mark Dickinson33841c32009-05-01 15:37:04 +00001537- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1538 floats with absolute value over 1e50. Also remove length
1539 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1540 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001541
Eric Smith741191f2009-05-06 13:08:15 +00001542- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001543 format(complex(1, 2./3), '.5') now produces a sensible result.
1544
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001545- Issue #5864: Fix empty format code formatting for floats so that it
1546 never gives more than the requested number of significant digits.
1547
Eric Smith6dc46f52009-04-27 20:39:49 +00001548- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1549 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1550
Eric Smithcc32a112009-04-26 21:35:14 +00001551- Issue #5835: Deprecate PyOS_ascii_formatd.
1552
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001553- Issue #4971: Fix titlecase for characters that are their own
1554 titlecase, but not their own uppercase.
1555
Benjamin Peterson193152c2009-04-25 01:08:45 +00001556- Issue #5283: Setting __class__ in __del__ caused a segfault.
1557
Mark Dickinsonad476da2009-04-23 19:14:16 +00001558- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1559 z involves nans, infs or negative zeros.
1560
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001561- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001562
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001563- Issue #1869 (and many duplicates): make round(x, n) correctly
1564 rounded for a float x, by using the decimal <-> binary conversions
1565 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1566 consistently agrees with format(x, '.2f').
1567
Benjamin Petersonae937c02009-04-18 20:54:08 +00001568- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1569 some builtin types.
1570
Eric Smith0923d1d2009-04-16 20:16:10 +00001571- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1572
Eric Smith35e84722009-04-16 20:21:28 +00001573- Issue #5515: str.format() type 'n' combined with commas and leading
1574 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001575
1576- Implement PEP 378, Format Specifier for Thousands Separator, for
1577 floats.
1578
Mark Dickinson3370cce2009-04-17 22:40:53 +00001579- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001580 1e11, not 1e12. This avoids printing 13 significant digits in
1581 situations where only 12 of them are correct. Example problem
1582 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1583 long time.)
1584
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001585- Issue #1580: On most platforms, use a 'short' float repr: for a
1586 finite float x, repr(x) now outputs a string based on the shortest
1587 sequence of decimal digits that rounds to x. Previous behaviour was
1588 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001589 Another minor difference is that the new repr switches to
1590 exponential notation at 1e16 instead of the previous 1e17; this
1591 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001592
1593 There's a new sys attribute sys.float_repr_style, which takes
1594 the value 'short' to indicate that we're using short float repr,
1595 and 'legacy' if the short float repr isn't available for one
1596 reason or another.
1597
1598 The float repr change involves incorporating David Gay's 'perfect
1599 rounding' code into the Python core (it's in Python/dtoa.c). As a
1600 secondary consequence, all string-to-float and float-to-string
1601 conversions (including all float formatting operations) will be
1602 correctly rounded on these platforms.
1603
Georg Brandl442d3b32010-08-01 22:33:12 +00001604 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001605 this change does not apply.
1606
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001607- Issue #5759: float() didn't call __float__ on str subclasses.
1608
Georg Brandlabc38772009-04-12 15:51:51 +00001609- The string.maketrans() function is deprecated; there is a new static method
1610 maketrans() on the bytes and bytearray classes. This removes confusion about
1611 the types string.maketrans() is supposed to work with, and mirrors the
1612 methods available on the str class.
1613
R. David Murraydc6da8a2009-04-09 22:16:43 +00001614- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1615 its clarity and its speed.
1616
Matthias Klose091c7b12009-04-07 13:24:27 +00001617- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1618 to avoid compiler warnings.
1619
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001620- Issue #3739: The unicode-internal encoder now reports the number of characters
1621 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001756- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1757
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001758- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1759 byte, and the 'C' code only accepts a unicode character.
1760
Georg Brandl406b3d82009-04-11 21:24:37 +00001761- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1762 when hitting the recursion limit under certain circumstances.
1763
Brett Cannon0759dd62009-04-01 18:13:07 +00001764- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1765
Georg Brandlab6f2f62009-03-31 04:16:10 +00001766- Fix a segfault when running test_exceptions with coverage, caused by
1767 insufficient checks in accessors of Exception.__context__.
1768
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001769- Issue #5604: non-ASCII characters in module name passed to
1770 imp.find_module() were converted to UTF-8 while the path is
1771 converted to the default filesystem encoding, causing nonsense.
1772
Benjamin Peterson09832742009-03-26 17:15:46 +00001773- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001775- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1776 the end sys.path, for compatibility with the system install of Python.
1777
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001778- Issue #4688: Add a heuristic so that tuples and dicts containing only
1779 untrackable objects are not tracked by the garbage collector. This can
1780 reduce the size of collections and therefore the garbage collection overhead
1781 on long-running programs, depending on their particular use of datatypes.
1782
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001783- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1786
Mark Dickinsonbd792642009-03-18 20:06:12 +00001787- Issue #4258: Make it possible to use base 2**30 instead of base
1788 2**15 for the internal representation of integers, for performance
1789 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1790 --enable-big-digits option to configure, which overrides the
1791 default. Add sys.int_info structseq to provide information about
1792 the internal format.
1793
Mark Dickinson081dfee2009-03-18 14:47:41 +00001794- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1795 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1796 and sizeof(Py_UNICODE) == 2.
1797
Eric Smith8ec90442009-03-14 12:29:34 +00001798- Issue #5237: Allow auto-numbered fields in str.format(). For

1800
Antoine Pitrou652e7072009-03-13 19:25:20 +00001801- Issue #5392: when a very low recursion limit was set, the interpreter would
1802 abort with a fatal error after the recursion limit was hit twice.
1803
Matthias Klose042f1332009-04-04 14:32:42 +00001804- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Hye-Shik Chang944820b2009-04-02 10:33:16 +00001813- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
1814 error substitutions from non-strict codec error callbacks in
1815 incrementalencoder and StreamWriter.
1816
Georg Brandl33c28812009-04-01 23:07:29 +00001817- Issue #5656: Fix the coverage reporting when running the test suite with

1835
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001836- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1837 bytes already but the failure was non-obvious.
1838
Jesse Noller7af4ef82009-03-30 16:47:15 +00001839- Issue #5177: Multiprocessing's SocketListener class now uses

1850
Lars Gustäbel42e00912009-03-22 20:34:29 +00001851- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1852 forever on incomplete input. That caused tarfile.open() to hang when used
1853 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1854 partial bzip2 compressed data.
1855
Mark Dickinson79f52032009-03-17 23:12:51 +00001856- Issue #2110: Add support for thousands separator and 'n' type

1874 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001875 struct.error instead of returning b'\xff\xff\xff\xff'. The
1876 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1897
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001898- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1899 source has already been decoded into str.
1900
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001901- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1902 rotating the object pointer by 4 bits to the right.
1903
Mark Dickinson87ec0852009-02-09 17:15:59 +00001904- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1905 it now forces its argument to double before testing for infinity.
1906
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001907- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1908 returns a non-number type.
1909
Benjamin Peterson87618552009-02-08 15:00:52 +00001910- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001916
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001917- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001918 were suppressing all exceptions. These include list() and bytearray().
1919
Mark Dickinson1124e712009-01-28 21:25:58 +00001920- Issue #4707: round(x, n) now returns an integer if x is an integer.
1921 Previously it returned a float.
1922
Antoine Pitroub52ec782009-01-25 16:34:23 +00001923- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1924 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1925 evaluation loop is compiled with a new dispatch mechanism which gives
1926 speedups of up to 20%, depending on the system, on various benchmarks.
1927
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001928- Issue #4874: Most builtin decoders now reject unicode input.

1936 optional module state data.
1937
Mark Dickinson8055afd2009-01-17 10:04:45 +00001938- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1939 type to (void *).
1940
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001941- Issue #4935: The overflow checking code in the expandtabs() method common
1942 to str, bytes and bytearray could be optimized away by the compiler, letting
1943 the interpreter segfault instead of raising an error.
1944
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001945- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1946 __next__ method.
1947
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001948- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1957 common cases are optimized thanks to a dedicated fast path and a moderate
1958 amount of loop unrolling.
1959
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001960- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1961 collecting the oldest generation) so that allocating lots of objects without
1962 destroying them does not show quadratic performance. Based on a proposal by
1963 Martin von Löwis at
1964 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1965
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001966- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001967 having been closed (for instance, a read() call could return some
1968 previously buffered data). Patch by Dmitry Vasiliev.
1969
Antoine Pitrou05608432009-01-09 18:53:14 +00001970- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1971 flag to work properly. Furthermore, when specifying -u, the text stdout
1972 and stderr streams have line-by-line buffering enabled (the default being
1973 to buffer arbitrary chunks of data).
1974
Raymond Hettinger35631532009-01-09 03:58:09 +00001975- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1976 instead of ints (reducing its size from 4 to 8 times thereby reducing
1977 Python's overall memory).
1978
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001979- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1980 an existing .py counterpart, override the co_filename attributes of all
1981 code objects if the original filename is obsolete (which can happen if the
1982 file has been renamed, moved, or if it is accessed through different paths).
1983 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1984
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001985- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1986 one byte. Also fixes the meaning of len() so that it returns the number of
1987 items, rather than the size in bytes.
1988
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001989- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1990
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001991- Issue #4747: When the terminal does not use utf-8, executing a script with
1992 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1993

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001997- Issue #3680: Reference cycles created through a dict, set or deque iterator
1998 did not get collected.
1999
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002000- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2001 where the tp_hash and tp_dict slots are both NULL.
2002
Georg Brandlccc47b62008-12-28 11:44:14 +00002003- Issue #4759: None is now allowed as the first argument of
2004 bytearray.translate(). It was always allowed for bytes.translate().
2005
Skip Montanaro80072cb2008-12-23 03:51:14 +00002006- Added test case to ensure attempts to read from a file opened for writing
2007 fail.

2013
Antoine Pitrou621601a2008-12-17 23:18:19 +00002014- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2015 print elapsed times, not only when some objects are uncollectable /
2016 unreachable. Original patch by Neil Schemenauer.
2017
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002018- Issue #3439: Add a bit_length method to int.
2019
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002020- Issue #2173: When getting device encoding, check that return value of
2021 nl_langinfo is not the empty string. This was causing silent build
2022 failures on OS X.
2023
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002024- Issue #4597: Fixed several opcodes that weren't always propagating
2025 exceptions.
2026
2027- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002028 context manager returns a value that cannot be converted to a bool.
2029
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002030- Issue #4445: Replace "sizeof(PyBytesObject)" with
2031 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2032 bytes instances. On a typical machine this saves 3 bytes of memory
2033 (on average) per allocation of a bytes instance.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002614- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2615 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2616 the same behaviour as test_ttkguionly (and now also test_tk) which is to

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002620 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002621 from test support, which does the conversion.
