68 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
69
Antoine Pitroudedbbe62010-07-11 12:15:03 +000070- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
71 compiler.
72
Ezio Melotti25bc0192010-07-03 05:18:50 +000073- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
74 start byte and the continuation byte(s) are now considered invalid, instead
75 of the number of bytes specified by the start byte.
76 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
77 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
78 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

509 would be turned into a non-blocking SSL socket).
510
Antoine Pitrouec146182010-04-24 21:30:20 +0000511- Issue #5103: SSL handshake would ignore the socket timeout and block

1517 that would raise SystemError.
1518
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001519- Issue #5982: staticmethod and classmethod now expose the wrapped
1520 function with __func__.
1521
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001522- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001525- Issue #5829: complex("1e500") no longer raises OverflowError. This
1526 makes it consistent with float("1e500") and interpretation of real
1527 and imaginary literals.
1528
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001529- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1534 (1) inf and nan strings with trailing whitespace were incorrectly
1535 rejected; (2) parsing of strings representing infinities and nans
1536 was locale aware; and (3) the interpretation of fromhex('-nan')
1537 didn't match that of float('-nan').

1554
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001555- In unittest, using a skipping decorator on a class is now equivalent to
1556 skipping every test on the class. The ClassTestSuite class has been removed.
1557
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001558- Issue #6050: Don't fail extracting a directory from a zipfile if
1559 the directory already exists.
1560
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001561- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1562 than an int, which makes some operations possible under 64-bit Linux (e.g.
1563 DN_MULTISHOT with F_NOTIFY).
1564
Antoine Pitrou716c4442009-05-23 19:04:03 +00001565- Issue #5761: Add the name of the underlying file to the repr() of various

1570
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001571- Issue #1983: Fix functions taking or returning a process identifier to use

1586
Antoine Pitroue4501852009-05-14 18:55:55 +00001587- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1588 library. This means, for example, that opening an UTF-16 text file in
1589 append mode doesn't add a BOM at the end of the file if the file isn't
1590 empty.
1591
R. David Murray74b89242009-05-13 17:33:03 +00001592- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

1595
Georg Brandl442d3b32010-08-01 22:33:12 +00001596- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00001597 now it does. This also means getfp method now returns the real fp.

1640Core and Builtins
1641-----------------
1642
Mark Dickinson865e01a2009-05-07 16:37:01 +00001643- Issue #5914: Add new C API function PyOS_string_to_double, and
1644 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1645
Eric Smith741191f2009-05-06 13:08:15 +00001646- Issue #3382: float.__format__, complex.__format__, and %-formatting
1647 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1648 affects nan -> NAN and inf -> INF.
1649
Mark Hammond5a607a32009-05-06 08:04:54 +00001650- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1651 in all operations, including splitdrive, split, etc. splitunc() now issues
1652 a PendingDeprecation warning.
1653
Eric Smith63376222009-05-05 14:04:18 +00001654- Issue #5920: For float.__format__, change the behavior with the
1655 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1656 to be like 'g' but with at least one decimal point and with a
1657 default precision of 12. Previously, the behavior the same but with
1658 a default precision of 6. This more closely matches str(), and
1659 reduces surprises when adding alignment flags to the empty
1660 presentation type. This also affects the new complex.__format__ in
1661 the same way.
1662
Martin v. Löwis011e8422009-05-05 04:43:17 +00001663- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1664
R. David Murrayb18500d2009-05-04 22:59:07 +00001665- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1666 shadowed by classtype's, even if it was None. property now
1667 inserts the __doc__ into the subclass instance __dict__.
1668
Antoine Pitrou244651a2009-05-04 18:56:13 +00001669- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1670 sequences. Patch by Nick Barnes and Victor Stinner.
1671
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001672- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001673
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001674- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1675 received a new method, detach(). detach() disconnects the underlying stream
1676 from the buffer or text IO and returns it.
1677
Mark Dickinson33841c32009-05-01 15:37:04 +00001678- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1679 floats with absolute value over 1e50. Also remove length
1680 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1681 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001682
Eric Smith741191f2009-05-06 13:08:15 +00001683- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001684 format(complex(1, 2./3), '.5') now produces a sensible result.
1685
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001686- Issue #5864: Fix empty format code formatting for floats so that it
1687 never gives more than the requested number of significant digits.
1688
Eric Smith6dc46f52009-04-27 20:39:49 +00001689- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1690 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1691
Eric Smithcc32a112009-04-26 21:35:14 +00001692- Issue #5835: Deprecate PyOS_ascii_formatd.
1693
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001694- Issue #4971: Fix titlecase for characters that are their own
1695 titlecase, but not their own uppercase.
1696
Benjamin Peterson193152c2009-04-25 01:08:45 +00001697- Issue #5283: Setting __class__ in __del__ caused a segfault.
1698
Mark Dickinsonad476da2009-04-23 19:14:16 +00001699- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1700 z involves nans, infs or negative zeros.
1701
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001702- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001703
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001704- Issue #1869 (and many duplicates): make round(x, n) correctly
1705 rounded for a float x, by using the decimal <-> binary conversions
1706 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1707 consistently agrees with format(x, '.2f').
1708
Benjamin Petersonae937c02009-04-18 20:54:08 +00001709- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1710 some builtin types.
1711
Eric Smith0923d1d2009-04-16 20:16:10 +00001712- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1713
Eric Smith35e84722009-04-16 20:21:28 +00001714- Issue #5515: str.format() type 'n' combined with commas and leading
1715 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001716
1717- Implement PEP 378, Format Specifier for Thousands Separator, for
1718 floats.
1719
Mark Dickinson3370cce2009-04-17 22:40:53 +00001720- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001721 1e11, not 1e12. This avoids printing 13 significant digits in
1722 situations where only 12 of them are correct. Example problem
1723 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1724 long time.)
1725
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001726- Issue #1580: On most platforms, use a 'short' float repr: for a
1727 finite float x, repr(x) now outputs a string based on the shortest
1728 sequence of decimal digits that rounds to x. Previous behaviour was
1729 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001730 Another minor difference is that the new repr switches to
1731 exponential notation at 1e16 instead of the previous 1e17; this
1732 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001733
1734 There's a new sys attribute sys.float_repr_style, which takes
1735 the value 'short' to indicate that we're using short float repr,
1736 and 'legacy' if the short float repr isn't available for one
1737 reason or another.
1738
1739 The float repr change involves incorporating David Gay's 'perfect
1740 rounding' code into the Python core (it's in Python/dtoa.c). As a
1741 secondary consequence, all string-to-float and float-to-string
1742 conversions (including all float formatting operations) will be
1743 correctly rounded on these platforms.
1744
Georg Brandl442d3b32010-08-01 22:33:12 +00001745 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001746 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001748- Issue #5759: float() didn't call __float__ on str subclasses.
1749
Georg Brandlabc38772009-04-12 15:51:51 +00001750- The string.maketrans() function is deprecated; there is a new static method
1751 maketrans() on the bytes and bytearray classes. This removes confusion about
1752 the types string.maketrans() is supposed to work with, and mirrors the
1753 methods available on the str class.

2043 rotating the object pointer by 4 bits to the right.
2044
Mark Dickinson87ec0852009-02-09 17:15:59 +00002045- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2046 it now forces its argument to double before testing for infinity.
2047
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002048- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002057
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002058- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002059 were suppressing all exceptions. These include list() and bytearray().

2063
Antoine Pitroub52ec782009-01-25 16:34:23 +00002064- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2065 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2066 evaluation loop is compiled with a new dispatch mechanism which gives
2067 speedups of up to 20%, depending on the system, on various benchmarks.
2068

2077 optional module state data.
2078
Mark Dickinson8055afd2009-01-17 10:04:45 +00002079- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2080 type to (void *).
2081
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002082- Issue #4935: The overflow checking code in the expandtabs() method common
2083 to str, bytes and bytearray could be optimized away by the compiler, letting
2084 the interpreter segfault instead of raising an error.
2085
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002086- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2087 __next__ method.
2088
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002089- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2090 function no longer attempt to call the __long__ slot to convert an object
2091 to an integer. Only the __int__ and __trunc__ slots are examined.
2092
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002093- Issue #4893: Use NT threading on CE.

2096
Antoine Pitrouab868312009-01-10 15:40:25 +00002097- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2098 common cases are optimized thanks to a dedicated fast path and a moderate
2099 amount of loop unrolling.
2100
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002101- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2102 collecting the oldest generation) so that allocating lots of objects without
2103 destroying them does not show quadratic performance. Based on a proposal by
2104 Martin von Löwis at
2105 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2106
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002107- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002108 having been closed (for instance, a read() call could return some
2109 previously buffered data). Patch by Dmitry Vasiliev.
2110
Antoine Pitrou05608432009-01-09 18:53:14 +00002111- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2112 flag to work properly. Furthermore, when specifying -u, the text stdout
2113 and stderr streams have line-by-line buffering enabled (the default being
2114 to buffer arbitrary chunks of data).
2115
Raymond Hettinger35631532009-01-09 03:58:09 +00002116- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2117 instead of ints (reducing its size from 4 to 8 times thereby reducing
2118 Python's overall memory).
2119
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002120- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2121 an existing .py counterpart, override the co_filename attributes of all
2122 code objects if the original filename is obsolete (which can happen if the
2123 file has been renamed, moved, or if it is accessed through different paths).
2124 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2125
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002126- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2127 one byte. Also fixes the meaning of len() so that it returns the number of
2128 items, rather than the size in bytes.
2129
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002130- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2131
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002132- Issue #4747: When the terminal does not use utf-8, executing a script with
2133 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2134
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002135- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

2143
Georg Brandlccc47b62008-12-28 11:44:14 +00002144- Issue #4759: None is now allowed as the first argument of
2145 bytearray.translate(). It was always allowed for bytes.translate().
2146
Skip Montanaro80072cb2008-12-23 03:51:14 +00002147- Added test case to ensure attempts to read from a file opened for writing
2148 fail.

2154
Antoine Pitrou621601a2008-12-17 23:18:19 +00002155- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2156 print elapsed times, not only when some objects are uncollectable /
2157 unreachable. Original patch by Neil Schemenauer.
2158

2160
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002161- Issue #2173: When getting device encoding, check that return value of
2162 nl_langinfo is not the empty string. This was causing silent build
2163 failures on OS X.
2164
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002165- Issue #4597: Fixed several opcodes that weren't always propagating
2166 exceptions.
2167
2168- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002169 context manager returns a value that cannot be converted to a bool.
2170
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002171- Issue #4445: Replace "sizeof(PyBytesObject)" with
2172 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2173 bytes instances. On a typical machine this saves 3 bytes of memory
2174 (on average) per allocation of a bytes instance.
2175
Christian Heimesa872de52008-12-05 08:26:55 +00002176- Issue #4533: File read operation was dreadfully slow due to a slowly
2177 growing read buffer. Fixed by using the same growth rate algorithm as
2178 Python 2.x.
2179
Antoine Pitrou5504e892008-12-06 21:27:53 +00002180- Issue #4509: Various issues surrounding resize of bytearray objects to
2181 which there are buffer exports (e.g. memoryview instances).
2182
Georg Brandlf9734072008-12-07 15:30:06 +00002183- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2184 method on file objects with closefd=False. The file descriptor is still
2185 kept open but the file object behaves like a closed file. The ``FileIO``
2186 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002187
Antoine Pitroubc420402008-12-07 20:14:49 +00002188- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002195- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2196 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2197 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2198 of using the replace error handler in PyUnicode_DecodeUTF8().

2584 Alexander Belopolsky.
2585
