14
Raymond Hettingerc6d80c12010-08-08 00:56:52 +000015- Issue #8814: function annotations (the ``__annotations__`` attribute)
16 are now included in the set of attributes copied by default by
17 functools.wraps and functools.update_wrapper. Patch by Terrence Cole.
18

22 output with no type specifier failed to match the str output:
23
24 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
25 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
26

Ezio Melotti25bc0192010-07-03 05:18:50 +000030- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
31 start byte and the continuation byte(s) are now considered invalid, instead
32 of the number of bytes specified by the start byte.
33 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
34 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
35 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
36 Previous versions returned a single u'\ufffd'.

1411
Eric Smith63376222009-05-05 14:04:18 +00001412- Issue #5920: For float.__format__, change the behavior with the
1413 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1414 to be like 'g' but with at least one decimal point and with a
1415 default precision of 12. Previously, the behavior the same but with
1416 a default precision of 6. This more closely matches str(), and
1417 reduces surprises when adding alignment flags to the empty
1418 presentation type. This also affects the new complex.__format__ in
1419 the same way.
1420
Martin v. Löwis011e8422009-05-05 04:43:17 +00001421- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001432- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1433 received a new method, detach(). detach() disconnects the underlying stream
1434 from the buffer or text IO and returns it.
1435
Mark Dickinson33841c32009-05-01 15:37:04 +00001436- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1437 floats with absolute value over 1e50. Also remove length
1438 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001460- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001461
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001462- Issue #1869 (and many duplicates): make round(x, n) correctly
1463 rounded for a float x, by using the decimal <-> binary conversions
1464 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1465 consistently agrees with format(x, '.2f').
1466
Benjamin Petersonae937c02009-04-18 20:54:08 +00001467- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1468 some builtin types.
1469
Eric Smith0923d1d2009-04-16 20:16:10 +00001470- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1471
Eric Smith35e84722009-04-16 20:21:28 +00001472- Issue #5515: str.format() type 'n' combined with commas and leading
1473 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001474
1475- Implement PEP 378, Format Specifier for Thousands Separator, for
1476 floats.
1477
Mark Dickinson3370cce2009-04-17 22:40:53 +00001478- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001479 1e11, not 1e12. This avoids printing 13 significant digits in
1480 situations where only 12 of them are correct. Example problem
1481 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1482 long time.)
1483
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001484- Issue #1580: On most platforms, use a 'short' float repr: for a
1485 finite float x, repr(x) now outputs a string based on the shortest
1486 sequence of decimal digits that rounds to x. Previous behaviour was
1487 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001488 Another minor difference is that the new repr switches to
1489 exponential notation at 1e16 instead of the previous 1e17; this
1490 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001491
1492 There's a new sys attribute sys.float_repr_style, which takes
1493 the value 'short' to indicate that we're using short float repr,
1494 and 'legacy' if the short float repr isn't available for one
1495 reason or another.
1496
1497 The float repr change involves incorporating David Gay's 'perfect
1498 rounding' code into the Python core (it's in Python/dtoa.c). As a
1499 secondary consequence, all string-to-float and float-to-string
1500 conversions (including all float formatting operations) will be
1501 correctly rounded on these platforms.
1502
Georg Brandl442d3b32010-08-01 22:33:12 +00001503 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001504 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001506- Issue #5759: float() didn't call __float__ on str subclasses.
1507
Georg Brandlabc38772009-04-12 15:51:51 +00001508- The string.maketrans() function is deprecated; there is a new static method
1509 maketrans() on the bytes and bytearray classes. This removes confusion about
1510 the types string.maketrans() is supposed to work with, and mirrors the
1511 methods available on the str class.
1512
R. David Murraydc6da8a2009-04-09 22:16:43 +00001513- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1676
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001677- Issue #4688: Add a heuristic so that tuples and dicts containing only
1678 untrackable objects are not tracked by the garbage collector. This can
1679 reduce the size of collections and therefore the garbage collection overhead
1680 on long-running programs, depending on their particular use of datatypes.

1749
Lars Gustäbel42e00912009-03-22 20:34:29 +00001750- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1751 forever on incomplete input. That caused tarfile.open() to hang when used
1752 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1773 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001774 struct.error instead of returning b'\xff\xff\xff\xff'. The
1775 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1776 have been removed from the struct module.

1795 contained non ascii character on windows.
1796
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001797- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1798 source has already been decoded into str.
1799
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001800- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1801 rotating the object pointer by 4 bits to the right.
1802
Mark Dickinson87ec0852009-02-09 17:15:59 +00001803- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1804 it now forces its argument to double before testing for infinity.
1805
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001806- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1807 returns a non-number type.
1808
Benjamin Peterson87618552009-02-08 15:00:52 +00001809- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001815
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001816- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001817 were suppressing all exceptions. These include list() and bytearray().
1818
Mark Dickinson1124e712009-01-28 21:25:58 +00001819- Issue #4707: round(x, n) now returns an integer if x is an integer.
1820 Previously it returned a float.
1821
Antoine Pitroub52ec782009-01-25 16:34:23 +00001822- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1823 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1824 evaluation loop is compiled with a new dispatch mechanism which gives
1825 speedups of up to 20%, depending on the system, on various benchmarks.
1826
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001827- Issue #4874: Most builtin decoders now reject unicode input.

1833
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001834- Issue #4838: When a module is deallocated, free the memory backing the
1835 optional module state data.
1836
Mark Dickinson8055afd2009-01-17 10:04:45 +00001837- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1838 type to (void *).
1839
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001840- Issue #4935: The overflow checking code in the expandtabs() method common
1841 to str, bytes and bytearray could be optimized away by the compiler, letting
1842 the interpreter segfault instead of raising an error.
1843
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001844- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1845 __next__ method.
1846
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001847- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1848 function no longer attempt to call the __long__ slot to convert an object
1849 to an integer. Only the __int__ and __trunc__ slots are examined.
1850
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001851- Issue #4893: Use NT threading on CE.
1852
Martin v. Löwisec59d042009-01-12 07:59:10 +00001853- Issue #4915: Port sysmodule to Windows CE.
1854
Antoine Pitrouab868312009-01-10 15:40:25 +00001855- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1856 common cases are optimized thanks to a dedicated fast path and a moderate
1857 amount of loop unrolling.
1858
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001859- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1860 collecting the oldest generation) so that allocating lots of objects without
1861 destroying them does not show quadratic performance. Based on a proposal by
1862 Martin von Löwis at
1863 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1864
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001865- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001866 having been closed (for instance, a read() call could return some
1867 previously buffered data). Patch by Dmitry Vasiliev.
1868
Antoine Pitrou05608432009-01-09 18:53:14 +00001869- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1870 flag to work properly. Furthermore, when specifying -u, the text stdout
1871 and stderr streams have line-by-line buffering enabled (the default being
1872 to buffer arbitrary chunks of data).
1873
Raymond Hettinger35631532009-01-09 03:58:09 +00001874- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1875 instead of ints (reducing its size from 4 to 8 times thereby reducing
1876 Python's overall memory).
1877
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001878- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1879 an existing .py counterpart, override the co_filename attributes of all
1880 code objects if the original filename is obsolete (which can happen if the
1881 file has been renamed, moved, or if it is accessed through different paths).
1882 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1883
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001884- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1885 one byte. Also fixes the meaning of len() so that it returns the number of
1886 items, rather than the size in bytes.
1887
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001888- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1889
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001890- Issue #4747: When the terminal does not use utf-8, executing a script with
1891 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1892
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001893- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001894 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001895
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001896- Issue #3680: Reference cycles created through a dict, set or deque iterator
1897 did not get collected.
1898
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001899- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1900 where the tp_hash and tp_dict slots are both NULL.
1901
Georg Brandlccc47b62008-12-28 11:44:14 +00001902- Issue #4759: None is now allowed as the first argument of
1903 bytearray.translate(). It was always allowed for bytes.translate().
1904
Skip Montanaro80072cb2008-12-23 03:51:14 +00001905- Added test case to ensure attempts to read from a file opened for writing
1906 fail.
1907
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001908- Issue #3106: Speedup some comparisons (str/str and int/int).

1912
Antoine Pitrou621601a2008-12-17 23:18:19 +00001913- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1914 print elapsed times, not only when some objects are uncollectable /
1915 unreachable. Original patch by Neil Schemenauer.
1916
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001917- Issue #3439: Add a bit_length method to int.
1918
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001919- Issue #2173: When getting device encoding, check that return value of
1920 nl_langinfo is not the empty string. This was causing silent build
1921 failures on OS X.
1922
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001923- Issue #4597: Fixed several opcodes that weren't always propagating
1924 exceptions.
1925
1926- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001927 context manager returns a value that cannot be converted to a bool.
1928
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001929- Issue #4445: Replace "sizeof(PyBytesObject)" with
1930 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1931 bytes instances. On a typical machine this saves 3 bytes of memory
1932 (on average) per allocation of a bytes instance.
1933
Christian Heimesa872de52008-12-05 08:26:55 +00001934- Issue #4533: File read operation was dreadfully slow due to a slowly
1935 growing read buffer. Fixed by using the same growth rate algorithm as
1936 Python 2.x.
1937
Antoine Pitrou5504e892008-12-06 21:27:53 +00001938- Issue #4509: Various issues surrounding resize of bytearray objects to
1939 which there are buffer exports (e.g. memoryview instances).
1940
Georg Brandlf9734072008-12-07 15:30:06 +00001941- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1942 method on file objects with closefd=False. The file descriptor is still
1943 kept open but the file object behaves like a closed file. The ``FileIO``
1944 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001945
Antoine Pitroubc420402008-12-07 20:14:49 +00001946- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1947 larger than 1.

1952
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001953- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1954 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1955 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1956 of using the replace error handler in PyUnicode_DecodeUTF8().
