15
Antoine Pitrou98e2b452010-10-28 23:06:57 +000016- Issue #5437: A preallocated MemoryError instance should not hold traceback
17 data (including local variables caught in the stack trace) alive infinitely.

25 filenames encoded to the filesystem encoding with surrogateescape error
26 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
27
Benjamin Peterson0ad44fa2010-10-02 18:04:55 +000028- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a

32 resolution.
33
Mark Dickinsona67c70d2010-09-23 20:16:03 +000034- Issue #9930: Remove bogus subtype check that was causing (e.g.)

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

42
Antoine Pitrou3c6261a2010-09-08 12:48:12 +000043- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

71 output with no type specifier failed to match the str output:
72

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.

548
Antoine Pitrouec146182010-04-24 21:30:20 +0000549- Issue #5103: SSL handshake would ignore the socket timeout and block

1687 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1688
Eric Smith741191f2009-05-06 13:08:15 +00001689- Issue #3382: float.__format__, complex.__format__, and %-formatting
1690 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

1696
Eric Smith63376222009-05-05 14:04:18 +00001697- Issue #5920: For float.__format__, change the behavior with the
1698 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1699 to be like 'g' but with at least one decimal point and with a
1700 default precision of 12. Previously, the behavior the same but with
1701 a default precision of 6. This more closely matches str(), and
1702 reduces surprises when adding alignment flags to the empty
1703 presentation type. This also affects the new complex.__format__ in
1704 the same way.
1705
Martin v. Löwis011e8422009-05-05 04:43:17 +00001706- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1718 received a new method, detach(). detach() disconnects the underlying stream
1719 from the buffer or text IO and returns it.
1720
Mark Dickinson33841c32009-05-01 15:37:04 +00001721- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1722 floats with absolute value over 1e50. Also remove length
1723 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

1744
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001745- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001747- Issue #1869 (and many duplicates): make round(x, n) correctly
1748 rounded for a float x, by using the decimal <-> binary conversions
1749 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1750 consistently agrees with format(x, '.2f').
1751
Benjamin Petersonae937c02009-04-18 20:54:08 +00001752- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1756
Eric Smith35e84722009-04-16 20:21:28 +00001757- Issue #5515: str.format() type 'n' combined with commas and leading
1758 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001759
1760- Implement PEP 378, Format Specifier for Thousands Separator, for
1761 floats.
1762
Mark Dickinson3370cce2009-04-17 22:40:53 +00001763- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001764 1e11, not 1e12. This avoids printing 13 significant digits in
1765 situations where only 12 of them are correct. Example problem
1766 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1767 long time.)
1768
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001769- Issue #1580: On most platforms, use a 'short' float repr: for a
1770 finite float x, repr(x) now outputs a string based on the shortest
1771 sequence of decimal digits that rounds to x. Previous behaviour was
1772 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001773 Another minor difference is that the new repr switches to
1774 exponential notation at 1e16 instead of the previous 1e17; this
1775 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001776
1777 There's a new sys attribute sys.float_repr_style, which takes
1778 the value 'short' to indicate that we're using short float repr,
1779 and 'legacy' if the short float repr isn't available for one
1780 reason or another.
1781
1782 The float repr change involves incorporating David Gay's 'perfect
1783 rounding' code into the Python core (it's in Python/dtoa.c). As a
1784 secondary consequence, all string-to-float and float-to-string
1785 conversions (including all float formatting operations) will be
1786 correctly rounded on these platforms.
1787
Georg Brandl442d3b32010-08-01 22:33:12 +00001788 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001789 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001791- Issue #5759: float() didn't call __float__ on str subclasses.
1792
Georg Brandlabc38772009-04-12 15:51:51 +00001793- The string.maketrans() function is deprecated; there is a new static method
1794 maketrans() on the bytes and bytearray classes. This removes confusion about
1795 the types string.maketrans() is supposed to work with, and mirrors the
1796 methods available on the str class.

Lars Gustäbel42e00912009-03-22 20:34:29 +00002035- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2036 forever on incomplete input. That caused tarfile.open() to hang when used
2037 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2038 partial bzip2 compressed data.
2039
Mark Dickinson79f52032009-03-17 23:12:51 +00002040- Issue #2110: Add support for thousands separator and 'n' type

2044 '>' alignment characters.
2045
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00002046- The error detection code in FileIO.close() could fail to reflect the `errno`
2047 value, and report it as -1 instead.
2048
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00002049- Issue #5016: FileIO.seekable() could return False if the file position

2058 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002059 struct.error instead of returning b'\xff\xff\xff\xff'. The
2060 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2061 have been removed from the struct module.

2080 contained non ascii character on windows.
2081
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002082- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2083 source has already been decoded into str.
2084
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002085- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2086 rotating the object pointer by 4 bits to the right.
2087
Mark Dickinson87ec0852009-02-09 17:15:59 +00002088- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2089 it now forces its argument to double before testing for infinity.
2090
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002091- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2099 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002100
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002101- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002102 were suppressing all exceptions. These include list() and bytearray().
2103
Mark Dickinson1124e712009-01-28 21:25:58 +00002104- Issue #4707: round(x, n) now returns an integer if x is an integer.
2105 Previously it returned a float.
2106
Antoine Pitroub52ec782009-01-25 16:34:23 +00002107- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2108 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2109 evaluation loop is compiled with a new dispatch mechanism which gives
2110 speedups of up to 20%, depending on the system, on various benchmarks.
2111
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002112- Issue #4874: Most builtin decoders now reject unicode input.

2118
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002119- Issue #4838: When a module is deallocated, free the memory backing the
2120 optional module state data.
2121
Mark Dickinson8055afd2009-01-17 10:04:45 +00002122- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2123 type to (void *).
2124
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002125- Issue #4935: The overflow checking code in the expandtabs() method common
2126 to str, bytes and bytearray could be optimized away by the compiler, letting
2127 the interpreter segfault instead of raising an error.
2128
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002129- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2130 __next__ method.
2131
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002132- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2133 function no longer attempt to call the __long__ slot to convert an object
2134 to an integer. Only the __int__ and __trunc__ slots are examined.
2135
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002136- Issue #4893: Use NT threading on CE.
2137
Martin v. Löwisec59d042009-01-12 07:59:10 +00002138- Issue #4915: Port sysmodule to Windows CE.
2139
Antoine Pitrouab868312009-01-10 15:40:25 +00002140- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2141 common cases are optimized thanks to a dedicated fast path and a moderate
2142 amount of loop unrolling.
2143
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002144- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2145 collecting the oldest generation) so that allocating lots of objects without
2146 destroying them does not show quadratic performance. Based on a proposal by
2147 Martin von Löwis at
2148 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2149
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002150- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002151 having been closed (for instance, a read() call could return some
2152 previously buffered data). Patch by Dmitry Vasiliev.
2153
Antoine Pitrou05608432009-01-09 18:53:14 +00002154- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2155 flag to work properly. Furthermore, when specifying -u, the text stdout
2156 and stderr streams have line-by-line buffering enabled (the default being
2157 to buffer arbitrary chunks of data).
2158
Raymond Hettinger35631532009-01-09 03:58:09 +00002159- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2160 instead of ints (reducing its size from 4 to 8 times thereby reducing
2161 Python's overall memory).
2162
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002163- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2164 an existing .py counterpart, override the co_filename attributes of all
2165 code objects if the original filename is obsolete (which can happen if the
2166 file has been renamed, moved, or if it is accessed through different paths).
2167 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2168
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002169- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2170 one byte. Also fixes the meaning of len() so that it returns the number of
2171 items, rather than the size in bytes.
2172
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002173- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2174
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002175- Issue #4747: When the terminal does not use utf-8, executing a script with
2176 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2177
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002178- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002179 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002180
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002181- Issue #3680: Reference cycles created through a dict, set or deque iterator
2182 did not get collected.
2183
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002184- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2185 where the tp_hash and tp_dict slots are both NULL.
2186
Georg Brandlccc47b62008-12-28 11:44:14 +00002187- Issue #4759: None is now allowed as the first argument of
2188 bytearray.translate(). It was always allowed for bytes.translate().
2189
Skip Montanaro80072cb2008-12-23 03:51:14 +00002190- Added test case to ensure attempts to read from a file opened for writing
2191 fail.
2192
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002193- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002195- Issue #2183: Simplify and optimize bytecode for list, dict and set
2196 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2197
Antoine Pitrou621601a2008-12-17 23:18:19 +00002198- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2199 print elapsed times, not only when some objects are uncollectable /
2200 unreachable. Original patch by Neil Schemenauer.
2201
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002202- Issue #3439: Add a bit_length method to int.
2203
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002204- Issue #2173: When getting device encoding, check that return value of
2205 nl_langinfo is not the empty string. This was causing silent build
2206 failures on OS X.
2207
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002208- Issue #4597: Fixed several opcodes that weren't always propagating
2209 exceptions.
2210
2211- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002212 context manager returns a value that cannot be converted to a bool.
2213
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002214- Issue #4445: Replace "sizeof(PyBytesObject)" with
2215 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2216 bytes instances. On a typical machine this saves 3 bytes of memory
2217 (on average) per allocation of a bytes instance.
2218
Christian Heimesa872de52008-12-05 08:26:55 +00002219- Issue #4533: File read operation was dreadfully slow due to a slowly
2220 growing read buffer. Fixed by using the same growth rate algorithm as
2221 Python 2.x.
2222
Antoine Pitrou5504e892008-12-06 21:27:53 +00002223- Issue #4509: Various issues surrounding resize of bytearray objects to
2224 which there are buffer exports (e.g. memoryview instances).
2225
Georg Brandlf9734072008-12-07 15:30:06 +00002226- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2227 method on file objects with closefd=False. The file descriptor is still
2228 kept open but the file object behaves like a closed file. The ``FileIO``
2229 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002230
Antoine Pitroubc420402008-12-07 20:14:49 +00002231- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2237
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002238- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2239 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2240 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2241 of using the replace error handler in PyUnicode_DecodeUTF8().
