25 filenames encoded to the filesystem encoding with surrogateescape error
26 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
27

37
Antoine Pitrouc9a8df22010-09-09 20:33:43 +000038- Issue #9804: ascii() now always represents unicode surrogate pairs as

74 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
75
Antoine Pitroudedbbe62010-07-11 12:15:03 +000076- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
77 compiler.
78
Ezio Melotti25bc0192010-07-03 05:18:50 +000079- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
80 start byte and the continuation byte(s) are now considered invalid, instead
81 of the number of bytes specified by the start byte.
82 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
83 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
84 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1667 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

Eric Smith741191f2009-05-06 13:08:15 +00001669- Issue #3382: float.__format__, complex.__format__, and %-formatting

1674 in all operations, including splitdrive, split, etc. splitunc() now issues
1675 a PendingDeprecation warning.
1676
Eric Smith63376222009-05-05 14:04:18 +00001677- Issue #5920: For float.__format__, change the behavior with the
1678 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1679 to be like 'g' but with at least one decimal point and with a
1680 default precision of 12. Previously, the behavior the same but with
1681 a default precision of 6. This more closely matches str(), and
1682 reduces surprises when adding alignment flags to the empty
1683 presentation type. This also affects the new complex.__format__ in
1684 the same way.
1685
Martin v. Löwis011e8422009-05-05 04:43:17 +00001686- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00001688- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1689 shadowed by classtype's, even if it was None. property now
1690 inserts the __doc__ into the subclass instance __dict__.
1691
Antoine Pitrou244651a2009-05-04 18:56:13 +00001692- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

1694
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001695- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001696
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001697- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1698 received a new method, detach(). detach() disconnects the underlying stream
1699 from the buffer or text IO and returns it.
1700
Mark Dickinson33841c32009-05-01 15:37:04 +00001701- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1702 floats with absolute value over 1e50. Also remove length
1703 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1704 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001706- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001707 format(complex(1, 2./3), '.5') now produces a sensible result.
1708

1710 never gives more than the requested number of significant digits.
1711
Eric Smith6dc46f52009-04-27 20:39:49 +00001712- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00001722- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1723 z involves nans, infs or negative zeros.
1724
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001725- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001726
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001727- Issue #1869 (and many duplicates): make round(x, n) correctly
1728 rounded for a float x, by using the decimal <-> binary conversions
1729 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1730 consistently agrees with format(x, '.2f').
1731
Benjamin Petersonae937c02009-04-18 20:54:08 +00001732- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1733 some builtin types.

Eric Smith0923d1d2009-04-16 20:16:10 +00001735- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1736
Eric Smith35e84722009-04-16 20:21:28 +00001737- Issue #5515: str.format() type 'n' combined with commas and leading
1738 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001739
1740- Implement PEP 378, Format Specifier for Thousands Separator, for
1741 floats.
1742
Mark Dickinson3370cce2009-04-17 22:40:53 +00001743- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001744 1e11, not 1e12. This avoids printing 13 significant digits in
1745 situations where only 12 of them are correct. Example problem
1746 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1747 long time.)
1748
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001749- Issue #1580: On most platforms, use a 'short' float repr: for a
1750 finite float x, repr(x) now outputs a string based on the shortest
1751 sequence of decimal digits that rounds to x. Previous behaviour was
1752 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001753 Another minor difference is that the new repr switches to
1754 exponential notation at 1e16 instead of the previous 1e17; this
1755 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001756
1757 There's a new sys attribute sys.float_repr_style, which takes
1758 the value 'short' to indicate that we're using short float repr,
1759 and 'legacy' if the short float repr isn't available for one
1760 reason or another.
1761
1762 The float repr change involves incorporating David Gay's 'perfect
1763 rounding' code into the Python core (it's in Python/dtoa.c). As a
1764 secondary consequence, all string-to-float and float-to-string
1765 conversions (including all float formatting operations) will be
1766 correctly rounded on these platforms.
1767
Georg Brandl442d3b32010-08-01 22:33:12 +00001768 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001769 this change does not apply.
1770
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001771- Issue #5759: float() didn't call __float__ on str subclasses.
1772
Georg Brandlabc38772009-04-12 15:51:51 +00001773- The string.maketrans() function is deprecated; there is a new static method
1774 maketrans() on the bytes and bytearray classes. This removes confusion about
1775 the types string.maketrans() is supposed to work with, and mirrors the
1776 methods available on the str class.
1777
R. David Murraydc6da8a2009-04-09 22:16:43 +00001778- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1779 its clarity and its speed.
1780
Matthias Klose091c7b12009-04-07 13:24:27 +00001781- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'

1783
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001784- Issue #3739: The unicode-internal encoder now reports the number of characters

1943 untrackable objects are not tracked by the garbage collector. This can
1944 reduce the size of collections and therefore the garbage collection overhead
1945 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00002037- Issue #5463: In struct module, remove deprecated overflow wrapping
2038 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002039 struct.error instead of returning b'\xff\xff\xff\xff'. The
2040 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2041 have been removed from the struct module.

2064
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002065- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2066 rotating the object pointer by 4 bits to the right.
2067
Mark Dickinson87ec0852009-02-09 17:15:59 +00002068- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2069 it now forces its argument to double before testing for infinity.
2070
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002071- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002080
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002081- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002082 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002084- Issue #4707: round(x, n) now returns an integer if x is an integer.
2085 Previously it returned a float.
2086
Antoine Pitroub52ec782009-01-25 16:34:23 +00002087- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2088 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2089 evaluation loop is compiled with a new dispatch mechanism which gives
2090 speedups of up to 20%, depending on the system, on various benchmarks.
2091
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002092- Issue #4874: Most builtin decoders now reject unicode input.

2098
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002099- Issue #4838: When a module is deallocated, free the memory backing the
2100 optional module state data.
2101
Mark Dickinson8055afd2009-01-17 10:04:45 +00002102- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2103 type to (void *).
2104
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002105- Issue #4935: The overflow checking code in the expandtabs() method common
2106 to str, bytes and bytearray could be optimized away by the compiler, letting
2107 the interpreter segfault instead of raising an error.
2108
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002109- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2110 __next__ method.
2111
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002112- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2113 function no longer attempt to call the __long__ slot to convert an object
2114 to an integer. Only the __int__ and __trunc__ slots are examined.
2115
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002116- Issue #4893: Use NT threading on CE.
2117
Martin v. Löwisec59d042009-01-12 07:59:10 +00002118- Issue #4915: Port sysmodule to Windows CE.
2119
Antoine Pitrouab868312009-01-10 15:40:25 +00002120- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2121 common cases are optimized thanks to a dedicated fast path and a moderate
2122 amount of loop unrolling.
2123
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002124- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2125 collecting the oldest generation) so that allocating lots of objects without
2126 destroying them does not show quadratic performance. Based on a proposal by
2127 Martin von Löwis at
2128 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2129
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002130- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002131 having been closed (for instance, a read() call could return some
2132 previously buffered data). Patch by Dmitry Vasiliev.
2133
Antoine Pitrou05608432009-01-09 18:53:14 +00002134- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2135 flag to work properly. Furthermore, when specifying -u, the text stdout
2136 and stderr streams have line-by-line buffering enabled (the default being
2137 to buffer arbitrary chunks of data).
2138
Raymond Hettinger35631532009-01-09 03:58:09 +00002139- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2140 instead of ints (reducing its size from 4 to 8 times thereby reducing
2141 Python's overall memory).
2142
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002143- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2144 an existing .py counterpart, override the co_filename attributes of all
2145 code objects if the original filename is obsolete (which can happen if the
2146 file has been renamed, moved, or if it is accessed through different paths).
2147 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2148
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002149- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2150 one byte. Also fixes the meaning of len() so that it returns the number of
2151 items, rather than the size in bytes.
2152
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002153- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2154
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002155- Issue #4747: When the terminal does not use utf-8, executing a script with
2156 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2157
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002158- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002159 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002160
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002161- Issue #3680: Reference cycles created through a dict, set or deque iterator
2162 did not get collected.
2163
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002164- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2165 where the tp_hash and tp_dict slots are both NULL.
2166
Georg Brandlccc47b62008-12-28 11:44:14 +00002167- Issue #4759: None is now allowed as the first argument of
2168 bytearray.translate(). It was always allowed for bytes.translate().
2169
Skip Montanaro80072cb2008-12-23 03:51:14 +00002170- Added test case to ensure attempts to read from a file opened for writing
2171 fail.
2172
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002173- Issue #3106: Speedup some comparisons (str/str and int/int).
2174
Antoine Pitrouf289ae62008-12-18 11:06:25 +00002175- Issue #2183: Simplify and optimize bytecode for list, dict and set
2176 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2177
Antoine Pitrou621601a2008-12-17 23:18:19 +00002178- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2179 print elapsed times, not only when some objects are uncollectable /
2180 unreachable. Original patch by Neil Schemenauer.
2181
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002182- Issue #3439: Add a bit_length method to int.
2183
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002184- Issue #2173: When getting device encoding, check that return value of
2185 nl_langinfo is not the empty string. This was causing silent build
2186 failures on OS X.
2187
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002188- Issue #4597: Fixed several opcodes that weren't always propagating
2189 exceptions.
2190
2191- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002192 context manager returns a value that cannot be converted to a bool.
2193
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002194- Issue #4445: Replace "sizeof(PyBytesObject)" with
2195 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2196 bytes instances. On a typical machine this saves 3 bytes of memory
2197 (on average) per allocation of a bytes instance.
2198
Christian Heimesa872de52008-12-05 08:26:55 +00002199- Issue #4533: File read operation was dreadfully slow due to a slowly
2200 growing read buffer. Fixed by using the same growth rate algorithm as
2201 Python 2.x.
2202
Antoine Pitrou5504e892008-12-06 21:27:53 +00002203- Issue #4509: Various issues surrounding resize of bytearray objects to
2204 which there are buffer exports (e.g. memoryview instances).
2205
Georg Brandlf9734072008-12-07 15:30:06 +00002206- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2207 method on file objects with closefd=False. The file descriptor is still
2208 kept open but the file object behaves like a closed file. The ``FileIO``
2209 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002210
Antoine Pitroubc420402008-12-07 20:14:49 +00002211- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2212 larger than 1.
2213

2217
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002218- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2219 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2220 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2221 of using the replace error handler in PyUnicode_DecodeUTF8().
