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'.

R. David Murrayf870d872010-05-06 01:53:03 +0000315- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
316 character sets will now consistently use a Content-Transfer-Encoding of
317 7bit rather than sometimes being marked as 8bit.

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

341 not just SIGCHLD.
342
Lars Gustäbelf7317f92010-04-29 15:42:25 +0000343- Issue #8464: tarfile no longer creates files with execute permissions set

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".

404
Victor Stinnerf7351b42010-04-13 11:09:22 +0000405- Issue #8383: pickle and pickletools use surrogatepass error handler when
406 encoding unicode as utf8 to support lone surrogates and stay compatible with
407 Python 2.x and 3.0
408
Florent Xicluna9b0e9182010-03-28 11:42:38 +0000409- Issue #8179: Fix macpath.realpath() on a non-existing path.
410
Antoine Pitrou9004edd2010-03-23 00:28:26 +0000411- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

413 Initial patch by Bertrand Janin.
414
Antoine Pitrou9f274b12010-03-22 20:12:40 +0000415- Issue #7512: shutil.copystat() could raise an OSError when the filesystem

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.

450 compared to other unix systems. In particular, os.getgroups() does
451 not reflect any changes made using os.setgroups() but basicly always

1444 default precision of 12. Previously, the behavior the same but with
1445 a default precision of 6. This more closely matches str(), and
1446 reduces surprises when adding alignment flags to the empty

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001461- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1462 received a new method, detach(). detach() disconnects the underlying stream
1463 from the buffer or text IO and returns it.
1464
Mark Dickinson33841c32009-05-01 15:37:04 +00001465- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1466 floats with absolute value over 1e50. Also remove length
1467 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1468 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001470- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001471 format(complex(1, 2./3), '.5') now produces a sensible result.
1472
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001473- Issue #5864: Fix empty format code formatting for floats so that it
1474 never gives more than the requested number of significant digits.
1475
Eric Smith6dc46f52009-04-27 20:39:49 +00001476- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1477 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1478
Eric Smithcc32a112009-04-26 21:35:14 +00001479- Issue #5835: Deprecate PyOS_ascii_formatd.
1480
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001481- Issue #4971: Fix titlecase for characters that are their own
1482 titlecase, but not their own uppercase.
1483
Benjamin Peterson193152c2009-04-25 01:08:45 +00001484- Issue #5283: Setting __class__ in __del__ caused a segfault.
1485
Mark Dickinsonad476da2009-04-23 19:14:16 +00001486- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1487 z involves nans, infs or negative zeros.
1488
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001489- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001490
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001491- Issue #1869 (and many duplicates): make round(x, n) correctly
1492 rounded for a float x, by using the decimal <-> binary conversions
1493 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1494 consistently agrees with format(x, '.2f').
1495
Benjamin Petersonae937c02009-04-18 20:54:08 +00001496- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1497 some builtin types.
1498
Eric Smith0923d1d2009-04-16 20:16:10 +00001499- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1500
Eric Smith35e84722009-04-16 20:21:28 +00001501- Issue #5515: str.format() type 'n' combined with commas and leading
1502 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001503
1504- Implement PEP 378, Format Specifier for Thousands Separator, for
1505 floats.
1506
Mark Dickinson3370cce2009-04-17 22:40:53 +00001507- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001508 1e11, not 1e12. This avoids printing 13 significant digits in
1509 situations where only 12 of them are correct. Example problem
1510 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1511 long time.)
1512
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001513- Issue #1580: On most platforms, use a 'short' float repr: for a
1514 finite float x, repr(x) now outputs a string based on the shortest
1515 sequence of decimal digits that rounds to x. Previous behaviour was
1516 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001517 Another minor difference is that the new repr switches to
1518 exponential notation at 1e16 instead of the previous 1e17; this
1519 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001520
1521 There's a new sys attribute sys.float_repr_style, which takes
1522 the value 'short' to indicate that we're using short float repr,
1523 and 'legacy' if the short float repr isn't available for one
1524 reason or another.
1525
1526 The float repr change involves incorporating David Gay's 'perfect
1527 rounding' code into the Python core (it's in Python/dtoa.c). As a
1528 secondary consequence, all string-to-float and float-to-string
1529 conversions (including all float formatting operations) will be
1530 correctly rounded on these platforms.
1531
Georg Brandl442d3b32010-08-01 22:33:12 +00001532 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001533 this change does not apply.
1534
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001535- Issue #5759: float() didn't call __float__ on str subclasses.
1536
Georg Brandlabc38772009-04-12 15:51:51 +00001537- The string.maketrans() function is deprecated; there is a new static method
1538 maketrans() on the bytes and bytearray classes. This removes confusion about
1539 the types string.maketrans() is supposed to work with, and mirrors the
1540 methods available on the str class.
1541
R. David Murraydc6da8a2009-04-09 22:16:43 +00001542- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1543 its clarity and its speed.
1544
Matthias Klose091c7b12009-04-07 13:24:27 +00001545- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1546 to avoid compiler warnings.
1547
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001548- Issue #3739: The unicode-internal encoder now reports the number of characters
1549 consumed like any other encoder (instead of the number of bytes).

1564
Vinay Sajipaffbd872009-06-11 10:11:47 +00001565- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +00001566 the right type checkings anymore.

1705
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001706- Issue #4688: Add a heuristic so that tuples and dicts containing only
1707 untrackable objects are not tracked by the garbage collector. This can
1708 reduce the size of collections and therefore the garbage collection overhead
1709 on long-running programs, depending on their particular use of datatypes.

1723 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1724 and sizeof(Py_UNICODE) == 2.
1725

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001803 struct.error instead of returning b'\xff\xff\xff\xff'. The
1804 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1830 rotating the object pointer by 4 bits to the right.
1831
Mark Dickinson87ec0852009-02-09 17:15:59 +00001832- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1833 it now forces its argument to double before testing for infinity.
1834
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001835- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001844
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001845- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001846 were suppressing all exceptions. These include list() and bytearray().

1850
Antoine Pitroub52ec782009-01-25 16:34:23 +00001851- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1852 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1853 evaluation loop is compiled with a new dispatch mechanism which gives
1854 speedups of up to 20%, depending on the system, on various benchmarks.
1855
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001856- Issue #4874: Most builtin decoders now reject unicode input.

1862
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001863- Issue #4838: When a module is deallocated, free the memory backing the
1864 optional module state data.
1865
Mark Dickinson8055afd2009-01-17 10:04:45 +00001866- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1867 type to (void *).
1868
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001869- Issue #4935: The overflow checking code in the expandtabs() method common
1870 to str, bytes and bytearray could be optimized away by the compiler, letting
1871 the interpreter segfault instead of raising an error.
1872
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001873- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1874 __next__ method.
1875
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001876- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1877 function no longer attempt to call the __long__ slot to convert an object
1878 to an integer. Only the __int__ and __trunc__ slots are examined.
1879
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001880- Issue #4893: Use NT threading on CE.
1881
Martin v. Löwisec59d042009-01-12 07:59:10 +00001882- Issue #4915: Port sysmodule to Windows CE.
1883
Antoine Pitrouab868312009-01-10 15:40:25 +00001884- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1885 common cases are optimized thanks to a dedicated fast path and a moderate
1886 amount of loop unrolling.
1887
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001888- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1889 collecting the oldest generation) so that allocating lots of objects without
1890 destroying them does not show quadratic performance. Based on a proposal by
1891 Martin von Löwis at
1892 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1893
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001894- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001895 having been closed (for instance, a read() call could return some
1896 previously buffered data). Patch by Dmitry Vasiliev.
1897
Antoine Pitrou05608432009-01-09 18:53:14 +00001898- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1899 flag to work properly. Furthermore, when specifying -u, the text stdout
1900 and stderr streams have line-by-line buffering enabled (the default being
1901 to buffer arbitrary chunks of data).
1902
Raymond Hettinger35631532009-01-09 03:58:09 +00001903- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1904 instead of ints (reducing its size from 4 to 8 times thereby reducing
1905 Python's overall memory).
1906
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001907- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1908 an existing .py counterpart, override the co_filename attributes of all
1909 code objects if the original filename is obsolete (which can happen if the
1910 file has been renamed, moved, or if it is accessed through different paths).
1911 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1912
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001913- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1914 one byte. Also fixes the meaning of len() so that it returns the number of
1915 items, rather than the size in bytes.
1916
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001917- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1918
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001919- Issue #4747: When the terminal does not use utf-8, executing a script with
1920 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1921
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001922- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001923 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001924
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001925- Issue #3680: Reference cycles created through a dict, set or deque iterator
1926 did not get collected.
1927
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001928- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1929 where the tp_hash and tp_dict slots are both NULL.
1930
Georg Brandlccc47b62008-12-28 11:44:14 +00001931- Issue #4759: None is now allowed as the first argument of
1932 bytearray.translate(). It was always allowed for bytes.translate().
1933
Skip Montanaro80072cb2008-12-23 03:51:14 +00001934- Added test case to ensure attempts to read from a file opened for writing
1935 fail.
1936
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001937- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001939- Issue #2183: Simplify and optimize bytecode for list, dict and set
1940 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1941
Antoine Pitrou621601a2008-12-17 23:18:19 +00001942- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1943 print elapsed times, not only when some objects are uncollectable /
1944 unreachable. Original patch by Neil Schemenauer.
1945
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001946- Issue #3439: Add a bit_length method to int.
1947
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001948- Issue #2173: When getting device encoding, check that return value of
1949 nl_langinfo is not the empty string. This was causing silent build
1950 failures on OS X.
1951
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001952- Issue #4597: Fixed several opcodes that weren't always propagating
1953 exceptions.
1954
1955- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001956 context manager returns a value that cannot be converted to a bool.
1957
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001958- Issue #4445: Replace "sizeof(PyBytesObject)" with
1959 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1960 bytes instances. On a typical machine this saves 3 bytes of memory
1961 (on average) per allocation of a bytes instance.
1962
Christian Heimesa872de52008-12-05 08:26:55 +00001963- Issue #4533: File read operation was dreadfully slow due to a slowly
1964 growing read buffer. Fixed by using the same growth rate algorithm as
1965 Python 2.x.
1966
Antoine Pitrou5504e892008-12-06 21:27:53 +00001967- Issue #4509: Various issues surrounding resize of bytearray objects to
1968 which there are buffer exports (e.g. memoryview instances).
1969
Georg Brandlf9734072008-12-07 15:30:06 +00001970- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1971 method on file objects with closefd=False. The file descriptor is still
1972 kept open but the file object behaves like a closed file. The ``FileIO``
1973 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001974
Antoine Pitroubc420402008-12-07 20:14:49 +00001975- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001982- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1983 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1984 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1985 of using the replace error handler in PyUnicode_DecodeUTF8().
