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'.

333
Mark Dickinsonece06972010-05-04 14:37:14 +0000334- Issue #8567: Fix precedence of signals in Decimal module: when a
335 Decimal operation raises multiple signals and more than one of those
336 signals is trapped, the specification determines the order in which
337 the signals should be handled. In many cases this order wasn't
338 being followed, leading to the wrong Python exception being raised.
339
Antoine Pitroufaf90072010-05-03 16:58:19 +0000340- Issue #7865: The close() method of :mod:`io` objects should not swallow

348 not just SIGCHLD.
349

361
Victor Stinnera27dcb72010-04-25 22:39:07 +0000362- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
363 and bytes strings for environment keys and values, and use
364 sys.getfilesystemencoding() instead of sys.getdefautltencoding()
365
Antoine Pitroue3123912010-04-25 22:26:08 +0000366- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
367 where the method could block indefinitely if called just before the
368 event loop started running. This also fixes the occasional freezes
369 witnessed in test_httpservers.
370
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000371- Issue #8524: When creating an SSL socket, the timeout value of the
372 original socket wasn't retained (instead, a socket with a positive timeout
373 would be turned into a non-blocking SSL socket).
374
Antoine Pitrouec146182010-04-24 21:30:20 +0000375- Issue #5103: SSL handshake would ignore the socket timeout and block
376 indefinitely if the other end didn't respond.
377
378- The do_handshake() method of SSL objects now adjusts the blocking mode of
379 the SSL structure if necessary (as other methods already do).
380
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000381- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
382 a non-infinite timeout. Also make that method friendlier with applications
383 wanting to continue using the socket in clear-text mode, by disabling
384 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

414 Python 2.x and 3.0

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

1451 default precision of 12. Previously, the behavior the same but with
1452 a default precision of 6. This more closely matches str(), and

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001468- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1469 received a new method, detach(). detach() disconnects the underlying stream
1470 from the buffer or text IO and returns it.
1471
Mark Dickinson33841c32009-05-01 15:37:04 +00001472- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1473 floats with absolute value over 1e50. Also remove length
1474 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1475 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001477- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001478 format(complex(1, 2./3), '.5') now produces a sensible result.
1479
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001480- Issue #5864: Fix empty format code formatting for floats so that it
1481 never gives more than the requested number of significant digits.
1482
Eric Smith6dc46f52009-04-27 20:39:49 +00001483- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1484 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1485
Eric Smithcc32a112009-04-26 21:35:14 +00001486- Issue #5835: Deprecate PyOS_ascii_formatd.

Martin v. Löwis71efeb72009-04-26 01:02:07 +00001488- Issue #4971: Fix titlecase for characters that are their own
1489 titlecase, but not their own uppercase.
1490
Benjamin Peterson193152c2009-04-25 01:08:45 +00001491- Issue #5283: Setting __class__ in __del__ caused a segfault.
1492
Mark Dickinsonad476da2009-04-23 19:14:16 +00001493- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1494 z involves nans, infs or negative zeros.
1495
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001496- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001497
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001498- Issue #1869 (and many duplicates): make round(x, n) correctly
1499 rounded for a float x, by using the decimal <-> binary conversions
1500 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1501 consistently agrees with format(x, '.2f').
1502
Benjamin Petersonae937c02009-04-18 20:54:08 +00001503- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1504 some builtin types.
1505
Eric Smith0923d1d2009-04-16 20:16:10 +00001506- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1507
Eric Smith35e84722009-04-16 20:21:28 +00001508- Issue #5515: str.format() type 'n' combined with commas and leading
1509 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001510
1511- Implement PEP 378, Format Specifier for Thousands Separator, for
1512 floats.
1513
Mark Dickinson3370cce2009-04-17 22:40:53 +00001514- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001515 1e11, not 1e12. This avoids printing 13 significant digits in
1516 situations where only 12 of them are correct. Example problem
1517 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1518 long time.)
1519
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001520- Issue #1580: On most platforms, use a 'short' float repr: for a
1521 finite float x, repr(x) now outputs a string based on the shortest
1522 sequence of decimal digits that rounds to x. Previous behaviour was
1523 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001524 Another minor difference is that the new repr switches to
1525 exponential notation at 1e16 instead of the previous 1e17; this
1526 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001527
1528 There's a new sys attribute sys.float_repr_style, which takes
1529 the value 'short' to indicate that we're using short float repr,
1530 and 'legacy' if the short float repr isn't available for one
1531 reason or another.
1532
1533 The float repr change involves incorporating David Gay's 'perfect
1534 rounding' code into the Python core (it's in Python/dtoa.c). As a
1535 secondary consequence, all string-to-float and float-to-string
1536 conversions (including all float formatting operations) will be
1537 correctly rounded on these platforms.
1538
Georg Brandl442d3b32010-08-01 22:33:12 +00001539 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001540 this change does not apply.
1541
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001542- Issue #5759: float() didn't call __float__ on str subclasses.
1543
Georg Brandlabc38772009-04-12 15:51:51 +00001544- The string.maketrans() function is deprecated; there is a new static method
1545 maketrans() on the bytes and bytearray classes. This removes confusion about
1546 the types string.maketrans() is supposed to work with, and mirrors the
1547 methods available on the str class.
1548
R. David Murraydc6da8a2009-04-09 22:16:43 +00001549- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1550 its clarity and its speed.
1551
Matthias Klose091c7b12009-04-07 13:24:27 +00001552- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1553 to avoid compiler warnings.
1554
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001555- Issue #3739: The unicode-internal encoder now reports the number of characters
1556 consumed like any other encoder (instead of the number of bytes).

1571
Vinay Sajipaffbd872009-06-11 10:11:47 +00001572- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +00001573 the right type checkings anymore.

1712
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001713- Issue #4688: Add a heuristic so that tuples and dicts containing only
1714 untrackable objects are not tracked by the garbage collector. This can
1715 reduce the size of collections and therefore the garbage collection overhead
1716 on long-running programs, depending on their particular use of datatypes.

1837 rotating the object pointer by 4 bits to the right.
1838
Mark Dickinson87ec0852009-02-09 17:15:59 +00001839- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1840 it now forces its argument to double before testing for infinity.
1841
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001842- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001851
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001852- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001853 were suppressing all exceptions. These include list() and bytearray().

1859 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1860 evaluation loop is compiled with a new dispatch mechanism which gives
1861 speedups of up to 20%, depending on the system, on various benchmarks.
1862
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001863- Issue #4874: Most builtin decoders now reject unicode input.

1869
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001870- Issue #4838: When a module is deallocated, free the memory backing the
1871 optional module state data.
1872
Mark Dickinson8055afd2009-01-17 10:04:45 +00001873- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1874 type to (void *).
1875
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001876- Issue #4935: The overflow checking code in the expandtabs() method common
1877 to str, bytes and bytearray could be optimized away by the compiler, letting
1878 the interpreter segfault instead of raising an error.
1879
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001880- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1881 __next__ method.
1882
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001883- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1884 function no longer attempt to call the __long__ slot to convert an object
1885 to an integer. Only the __int__ and __trunc__ slots are examined.
1886
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001887- Issue #4893: Use NT threading on CE.
1888

1890
Antoine Pitrouab868312009-01-10 15:40:25 +00001891- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1892 common cases are optimized thanks to a dedicated fast path and a moderate
1893 amount of loop unrolling.
1894
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001895- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1896 collecting the oldest generation) so that allocating lots of objects without
1897 destroying them does not show quadratic performance. Based on a proposal by
1898 Martin von Löwis at
1899 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1900
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001901- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001902 having been closed (for instance, a read() call could return some
1903 previously buffered data). Patch by Dmitry Vasiliev.
1904
Antoine Pitrou05608432009-01-09 18:53:14 +00001905- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1906 flag to work properly. Furthermore, when specifying -u, the text stdout
1907 and stderr streams have line-by-line buffering enabled (the default being
1908 to buffer arbitrary chunks of data).
1909
Raymond Hettinger35631532009-01-09 03:58:09 +00001910- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1911 instead of ints (reducing its size from 4 to 8 times thereby reducing
1912 Python's overall memory).
1913
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001914- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1915 an existing .py counterpart, override the co_filename attributes of all
1916 code objects if the original filename is obsolete (which can happen if the
1917 file has been renamed, moved, or if it is accessed through different paths).
1918 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1919
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001920- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1921 one byte. Also fixes the meaning of len() so that it returns the number of
1922 items, rather than the size in bytes.
1923
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001924- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1925
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001926- Issue #4747: When the terminal does not use utf-8, executing a script with
1927 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1928
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001929- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001930 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001931
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001932- Issue #3680: Reference cycles created through a dict, set or deque iterator
1933 did not get collected.
1934
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001935- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1936 where the tp_hash and tp_dict slots are both NULL.
1937
Georg Brandlccc47b62008-12-28 11:44:14 +00001938- Issue #4759: None is now allowed as the first argument of
1939 bytearray.translate(). It was always allowed for bytes.translate().
1940
Skip Montanaro80072cb2008-12-23 03:51:14 +00001941- Added test case to ensure attempts to read from a file opened for writing
1942 fail.
1943
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001944- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001946- Issue #2183: Simplify and optimize bytecode for list, dict and set
1947 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1948
Antoine Pitrou621601a2008-12-17 23:18:19 +00001949- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1950 print elapsed times, not only when some objects are uncollectable /
1951 unreachable. Original patch by Neil Schemenauer.
1952
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001953- Issue #3439: Add a bit_length method to int.
1954
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001955- Issue #2173: When getting device encoding, check that return value of
1956 nl_langinfo is not the empty string. This was causing silent build
1957 failures on OS X.
1958
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001959- Issue #4597: Fixed several opcodes that weren't always propagating
1960 exceptions.
1961
1962- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001963 context manager returns a value that cannot be converted to a bool.
1964
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001965- Issue #4445: Replace "sizeof(PyBytesObject)" with
1966 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1967 bytes instances. On a typical machine this saves 3 bytes of memory
1968 (on average) per allocation of a bytes instance.
1969
Christian Heimesa872de52008-12-05 08:26:55 +00001970- Issue #4533: File read operation was dreadfully slow due to a slowly
1971 growing read buffer. Fixed by using the same growth rate algorithm as
1972 Python 2.x.
1973
Antoine Pitrou5504e892008-12-06 21:27:53 +00001974- Issue #4509: Various issues surrounding resize of bytearray objects to
1975 which there are buffer exports (e.g. memoryview instances).
1976
Georg Brandlf9734072008-12-07 15:30:06 +00001977- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1978 method on file objects with closefd=False. The file descriptor is still
1979 kept open but the file object behaves like a closed file. The ``FileIO``
1980 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001981
Antoine Pitroubc420402008-12-07 20:14:49 +00001982- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1990 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1991 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1992 of using the replace error handler in PyUnicode_DecodeUTF8().
