Victor Stinner15244f72010-10-19 01:22:07 +000036- Issue #9713, #10114: Parser functions (eg. PyParser_ASTFromFile) expects
37 filenames encoded to the filesystem encoding with surrogateescape error

39
Benjamin Peterson0ad44fa2010-10-02 18:04:55 +000040- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a

54
Antoine Pitrou3c6261a2010-09-08 12:48:12 +000055- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

86 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
87
Antoine Pitroudedbbe62010-07-11 12:15:03 +000088- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
89 compiler.
90
Ezio Melotti25bc0192010-07-03 05:18:50 +000091- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
92 start byte and the continuation byte(s) are now considered invalid, instead
93 of the number of bytes specified by the start byte.
94 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
95 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
96 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

574 would be turned into a non-blocking SSL socket).
575
Antoine Pitrouec146182010-04-24 21:30:20 +0000576- Issue #5103: SSL handshake would ignore the socket timeout and block

1729 default precision of 12. Previously, the behavior the same but with
1730 a default precision of 6. This more closely matches str(), and
1731 reduces surprises when adding alignment flags to the empty

1752 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1753 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001755- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001756 format(complex(1, 2./3), '.5') now produces a sensible result.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001776- Issue #1869 (and many duplicates): make round(x, n) correctly
1777 rounded for a float x, by using the decimal <-> binary conversions
1778 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1779 consistently agrees with format(x, '.2f').
1780
Benjamin Petersonae937c02009-04-18 20:54:08 +00001781- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00001788
1789- Implement PEP 378, Format Specifier for Thousands Separator, for
1790 floats.
1791
Mark Dickinson3370cce2009-04-17 22:40:53 +00001792- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001793 1e11, not 1e12. This avoids printing 13 significant digits in
1794 situations where only 12 of them are correct. Example problem
1795 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1796 long time.)
1797
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001798- Issue #1580: On most platforms, use a 'short' float repr: for a
1799 finite float x, repr(x) now outputs a string based on the shortest
1800 sequence of decimal digits that rounds to x. Previous behaviour was
1801 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001802 Another minor difference is that the new repr switches to
1803 exponential notation at 1e16 instead of the previous 1e17; this
1804 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001805
1806 There's a new sys attribute sys.float_repr_style, which takes
1807 the value 'short' to indicate that we're using short float repr,
1808 and 'legacy' if the short float repr isn't available for one
1809 reason or another.
1810
1811 The float repr change involves incorporating David Gay's 'perfect
1812 rounding' code into the Python core (it's in Python/dtoa.c). As a
1813 secondary consequence, all string-to-float and float-to-string
1814 conversions (including all float formatting operations) will be
1815 correctly rounded on these platforms.
1816
Georg Brandl442d3b32010-08-01 22:33:12 +00001817 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001818 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001820- Issue #5759: float() didn't call __float__ on str subclasses.
1821
Georg Brandlabc38772009-04-12 15:51:51 +00001822- The string.maketrans() function is deprecated; there is a new static method
1823 maketrans() on the bytes and bytearray classes. This removes confusion about
1824 the types string.maketrans() is supposed to work with, and mirrors the
1825 methods available on the str class.

2115 rotating the object pointer by 4 bits to the right.
2116
Mark Dickinson87ec0852009-02-09 17:15:59 +00002117- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2118 it now forces its argument to double before testing for infinity.
2119
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002120- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002129
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002130- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002131 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002133- Issue #4707: round(x, n) now returns an integer if x is an integer.
2134 Previously it returned a float.
2135
Antoine Pitroub52ec782009-01-25 16:34:23 +00002136- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2137 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2138 evaluation loop is compiled with a new dispatch mechanism which gives
2139 speedups of up to 20%, depending on the system, on various benchmarks.
2140
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002141- Issue #4874: Most builtin decoders now reject unicode input.

2147
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002148- Issue #4838: When a module is deallocated, free the memory backing the
2149 optional module state data.
2150
Mark Dickinson8055afd2009-01-17 10:04:45 +00002151- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2152 type to (void *).
2153
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002154- Issue #4935: The overflow checking code in the expandtabs() method common
2155 to str, bytes and bytearray could be optimized away by the compiler, letting
2156 the interpreter segfault instead of raising an error.
2157
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002158- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2159 __next__ method.
2160
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002161- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2162 function no longer attempt to call the __long__ slot to convert an object
2163 to an integer. Only the __int__ and __trunc__ slots are examined.
2164
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002165- Issue #4893: Use NT threading on CE.
2166
Martin v. Löwisec59d042009-01-12 07:59:10 +00002167- Issue #4915: Port sysmodule to Windows CE.
2168
Antoine Pitrouab868312009-01-10 15:40:25 +00002169- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2170 common cases are optimized thanks to a dedicated fast path and a moderate
2171 amount of loop unrolling.
2172
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002173- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2174 collecting the oldest generation) so that allocating lots of objects without
2175 destroying them does not show quadratic performance. Based on a proposal by
2176 Martin von Löwis at
2177 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2178
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002179- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002180 having been closed (for instance, a read() call could return some
2181 previously buffered data). Patch by Dmitry Vasiliev.
2182
Antoine Pitrou05608432009-01-09 18:53:14 +00002183- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2184 flag to work properly. Furthermore, when specifying -u, the text stdout
2185 and stderr streams have line-by-line buffering enabled (the default being
2186 to buffer arbitrary chunks of data).
2187
Raymond Hettinger35631532009-01-09 03:58:09 +00002188- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2189 instead of ints (reducing its size from 4 to 8 times thereby reducing
2190 Python's overall memory).
2191
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002192- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2193 an existing .py counterpart, override the co_filename attributes of all
2194 code objects if the original filename is obsolete (which can happen if the
2195 file has been renamed, moved, or if it is accessed through different paths).
2196 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2197
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002198- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2199 one byte. Also fixes the meaning of len() so that it returns the number of
2200 items, rather than the size in bytes.
2201
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002202- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2203
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002204- Issue #4747: When the terminal does not use utf-8, executing a script with
2205 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2206
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002207- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002208 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002209
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002210- Issue #3680: Reference cycles created through a dict, set or deque iterator
2211 did not get collected.
2212
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002213- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2214 where the tp_hash and tp_dict slots are both NULL.
2215
Georg Brandlccc47b62008-12-28 11:44:14 +00002216- Issue #4759: None is now allowed as the first argument of
2217 bytearray.translate(). It was always allowed for bytes.translate().
2218
Skip Montanaro80072cb2008-12-23 03:51:14 +00002219- Added test case to ensure attempts to read from a file opened for writing
2220 fail.
2221
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002222- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002224- Issue #2183: Simplify and optimize bytecode for list, dict and set
2225 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2226
Antoine Pitrou621601a2008-12-17 23:18:19 +00002227- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2228 print elapsed times, not only when some objects are uncollectable /
2229 unreachable. Original patch by Neil Schemenauer.
2230
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002231- Issue #3439: Add a bit_length method to int.
2232
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002233- Issue #2173: When getting device encoding, check that return value of
2234 nl_langinfo is not the empty string. This was causing silent build
2235 failures on OS X.
2236
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002237- Issue #4597: Fixed several opcodes that weren't always propagating
2238 exceptions.
2239
2240- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002241 context manager returns a value that cannot be converted to a bool.
2242
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002243- Issue #4445: Replace "sizeof(PyBytesObject)" with
2244 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2245 bytes instances. On a typical machine this saves 3 bytes of memory
2246 (on average) per allocation of a bytes instance.
2247
Christian Heimesa872de52008-12-05 08:26:55 +00002248- Issue #4533: File read operation was dreadfully slow due to a slowly
2249 growing read buffer. Fixed by using the same growth rate algorithm as
2250 Python 2.x.
2251
Antoine Pitrou5504e892008-12-06 21:27:53 +00002252- Issue #4509: Various issues surrounding resize of bytearray objects to
2253 which there are buffer exports (e.g. memoryview instances).
2254
Georg Brandlf9734072008-12-07 15:30:06 +00002255- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2256 method on file objects with closefd=False. The file descriptor is still
2257 kept open but the file object behaves like a closed file. The ``FileIO``
2258 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002259
Antoine Pitroubc420402008-12-07 20:14:49 +00002260- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2261 larger than 1.

2266
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002267- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2268 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2269 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2270 of using the replace error handler in PyUnicode_DecodeUTF8().
