Ezio Melotti25bc0192010-07-03 05:18:50 +000033- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
34 start byte and the continuation byte(s) are now considered invalid, instead
35 of the number of bytes specified by the start byte.
36 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
37 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
38 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
39 Previous versions returned a single u'\ufffd'.

326
Mark Dickinsonece06972010-05-04 14:37:14 +0000327- Issue #8567: Fix precedence of signals in Decimal module: when a
328 Decimal operation raises multiple signals and more than one of those
329 signals is trapped, the specification determines the order in which
330 the signals should be handled. In many cases this order wasn't
331 being followed, leading to the wrong Python exception being raised.
332
Antoine Pitroufaf90072010-05-03 16:58:19 +0000333- Issue #7865: The close() method of :mod:`io` objects should not swallow

335 close() several times is supported. Patch by Pascal Chambon.
336
Antoine Pitrou336e54f2010-05-02 20:06:54 +0000337- Issue #4687: Fix accuracy of garbage collection runtimes displayed with

353 Sridhar Ratnakumar.
354
Victor Stinnera27dcb72010-04-25 22:39:07 +0000355- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
356 and bytes strings for environment keys and values, and use
357 sys.getfilesystemencoding() instead of sys.getdefautltencoding()
358
Antoine Pitroue3123912010-04-25 22:26:08 +0000359- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
360 where the method could block indefinitely if called just before the
361 event loop started running. This also fixes the occasional freezes
362 witnessed in test_httpservers.
363
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000364- Issue #8524: When creating an SSL socket, the timeout value of the
365 original socket wasn't retained (instead, a socket with a positive timeout
366 would be turned into a non-blocking SSL socket).
367
Antoine Pitrouec146182010-04-24 21:30:20 +0000368- Issue #5103: SSL handshake would ignore the socket timeout and block
369 indefinitely if the other end didn't respond.
370
371- The do_handshake() method of SSL objects now adjusts the blocking mode of
372 the SSL structure if necessary (as other methods already do).
373
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000374- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
375 a non-infinite timeout. Also make that method friendlier with applications
376 wanting to continue using the socket in clear-text mode, by disabling
377 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

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

407 Python 2.x and 3.0

410
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000411- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

Antoine Pitroued6c8932010-03-26 19:38:11 +0000419- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
420 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
421 reads and writes are always retried by OpenSSL itself.

1439 to be like 'g' but with at least one decimal point and with a
1440 default precision of 12. Previously, the behavior the same but with
1441 a default precision of 6. This more closely matches str(), and
1442 reduces surprises when adding alignment flags to the empty
1443 presentation type. This also affects the new complex.__format__ in
1444 the same way.

Mark Dickinson33841c32009-05-01 15:37:04 +00001461- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1462 floats with absolute value over 1e50. Also remove length
1463 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1464 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001466- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001467 format(complex(1, 2./3), '.5') now produces a sensible result.

Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001485- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001487- Issue #1869 (and many duplicates): make round(x, n) correctly
1488 rounded for a float x, by using the decimal <-> binary conversions
1489 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1490 consistently agrees with format(x, '.2f').
1491
Benjamin Petersonae937c02009-04-18 20:54:08 +00001492- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1496
Eric Smith35e84722009-04-16 20:21:28 +00001497- Issue #5515: str.format() type 'n' combined with commas and leading
1498 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001499
1500- Implement PEP 378, Format Specifier for Thousands Separator, for
1501 floats.
1502
Mark Dickinson3370cce2009-04-17 22:40:53 +00001503- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001504 1e11, not 1e12. This avoids printing 13 significant digits in
1505 situations where only 12 of them are correct. Example problem
1506 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1507 long time.)
1508
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001509- Issue #1580: On most platforms, use a 'short' float repr: for a
1510 finite float x, repr(x) now outputs a string based on the shortest
1511 sequence of decimal digits that rounds to x. Previous behaviour was
1512 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001513 Another minor difference is that the new repr switches to
1514 exponential notation at 1e16 instead of the previous 1e17; this
1515 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001516
1517 There's a new sys attribute sys.float_repr_style, which takes
1518 the value 'short' to indicate that we're using short float repr,
1519 and 'legacy' if the short float repr isn't available for one
1520 reason or another.
1521
1522 The float repr change involves incorporating David Gay's 'perfect
1523 rounding' code into the Python core (it's in Python/dtoa.c). As a
1524 secondary consequence, all string-to-float and float-to-string
1525 conversions (including all float formatting operations) will be
1526 correctly rounded on these platforms.
1527
Georg Brandl442d3b32010-08-01 22:33:12 +00001528 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001529 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001531- Issue #5759: float() didn't call __float__ on str subclasses.
1532
Georg Brandlabc38772009-04-12 15:51:51 +00001533- The string.maketrans() function is deprecated; there is a new static method
1534 maketrans() on the bytes and bytearray classes. This removes confusion about
1535 the types string.maketrans() is supposed to work with, and mirrors the
1536 methods available on the str class.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001799 struct.error instead of returning b'\xff\xff\xff\xff'. The
1800 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00001828- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1829 it now forces its argument to double before testing for infinity.
1830
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001831- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001840
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001841- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001842 were suppressing all exceptions. These include list() and bytearray().
1843
Mark Dickinson1124e712009-01-28 21:25:58 +00001844- Issue #4707: round(x, n) now returns an integer if x is an integer.

1846
Antoine Pitroub52ec782009-01-25 16:34:23 +00001847- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1848 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1849 evaluation loop is compiled with a new dispatch mechanism which gives
1850 speedups of up to 20%, depending on the system, on various benchmarks.
1851
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001852- Issue #4874: Most builtin decoders now reject unicode input.

1858
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001859- Issue #4838: When a module is deallocated, free the memory backing the
1860 optional module state data.
1861
Mark Dickinson8055afd2009-01-17 10:04:45 +00001862- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1863 type to (void *).
1864
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001865- Issue #4935: The overflow checking code in the expandtabs() method common
1866 to str, bytes and bytearray could be optimized away by the compiler, letting
1867 the interpreter segfault instead of raising an error.
1868
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001869- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1870 __next__ method.
1871
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001872- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1873 function no longer attempt to call the __long__ slot to convert an object
1874 to an integer. Only the __int__ and __trunc__ slots are examined.
1875
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001876- Issue #4893: Use NT threading on CE.
1877

1879
Antoine Pitrouab868312009-01-10 15:40:25 +00001880- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1881 common cases are optimized thanks to a dedicated fast path and a moderate
1882 amount of loop unrolling.
1883
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001884- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1885 collecting the oldest generation) so that allocating lots of objects without
1886 destroying them does not show quadratic performance. Based on a proposal by
1887 Martin von Löwis at
1888 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1889
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001890- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001891 having been closed (for instance, a read() call could return some
1892 previously buffered data). Patch by Dmitry Vasiliev.
1893
Antoine Pitrou05608432009-01-09 18:53:14 +00001894- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1895 flag to work properly. Furthermore, when specifying -u, the text stdout
1896 and stderr streams have line-by-line buffering enabled (the default being
1897 to buffer arbitrary chunks of data).
1898
Raymond Hettinger35631532009-01-09 03:58:09 +00001899- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1900 instead of ints (reducing its size from 4 to 8 times thereby reducing
1901 Python's overall memory).
1902
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001903- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1904 an existing .py counterpart, override the co_filename attributes of all
1905 code objects if the original filename is obsolete (which can happen if the
1906 file has been renamed, moved, or if it is accessed through different paths).
1907 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1908
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001909- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1910 one byte. Also fixes the meaning of len() so that it returns the number of
1911 items, rather than the size in bytes.
1912
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001913- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1914
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001915- Issue #4747: When the terminal does not use utf-8, executing a script with
1916 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1917
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001918- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001919 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001920
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001921- Issue #3680: Reference cycles created through a dict, set or deque iterator
1922 did not get collected.
1923
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001924- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1925 where the tp_hash and tp_dict slots are both NULL.
1926
Georg Brandlccc47b62008-12-28 11:44:14 +00001927- Issue #4759: None is now allowed as the first argument of
1928 bytearray.translate(). It was always allowed for bytes.translate().
1929
Skip Montanaro80072cb2008-12-23 03:51:14 +00001930- Added test case to ensure attempts to read from a file opened for writing
1931 fail.
1932
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001933- Issue #3106: Speedup some comparisons (str/str and int/int).

1936 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1937
Antoine Pitrou621601a2008-12-17 23:18:19 +00001938- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1939 print elapsed times, not only when some objects are uncollectable /
1940 unreachable. Original patch by Neil Schemenauer.
1941
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001942- Issue #3439: Add a bit_length method to int.
1943
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001944- Issue #2173: When getting device encoding, check that return value of
1945 nl_langinfo is not the empty string. This was causing silent build
1946 failures on OS X.
1947
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001948- Issue #4597: Fixed several opcodes that weren't always propagating
1949 exceptions.
1950
1951- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001952 context manager returns a value that cannot be converted to a bool.
1953
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001954- Issue #4445: Replace "sizeof(PyBytesObject)" with
1955 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1956 bytes instances. On a typical machine this saves 3 bytes of memory
1957 (on average) per allocation of a bytes instance.
1958
Christian Heimesa872de52008-12-05 08:26:55 +00001959- Issue #4533: File read operation was dreadfully slow due to a slowly
1960 growing read buffer. Fixed by using the same growth rate algorithm as
1961 Python 2.x.
1962
Antoine Pitrou5504e892008-12-06 21:27:53 +00001963- Issue #4509: Various issues surrounding resize of bytearray objects to
1964 which there are buffer exports (e.g. memoryview instances).
1965
Georg Brandlf9734072008-12-07 15:30:06 +00001966- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1967 method on file objects with closefd=False. The file descriptor is still
1968 kept open but the file object behaves like a closed file. The ``FileIO``
1969 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001970
Antoine Pitroubc420402008-12-07 20:14:49 +00001971- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1979 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1980 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1981 of using the replace error handler in PyUnicode_DecodeUTF8().
