12Core and Builtins
13-----------------
14
Antoine Pitrou79eee6b2009-02-13 14:01:05 +000015- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
16 rotating the object pointer by 4 bits to the right.
17
Mark Dickinson87ec0852009-02-09 17:15:59 +000018- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
19 it now forces its argument to double before testing for infinity.
20
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +000021- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
22 returns a non-number type.
23
Benjamin Peterson87618552009-02-08 15:00:52 +000024- Issue #5182: Removed memoryview.__str__.
25
Mark Dickinsonc008a172009-02-01 13:59:22 +000026- Issue #1717: Removed builtin cmp() function, dropped tp_compare
27 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +000028 the type definition cmpfunc. The tp_compare slot has been renamed
29 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +000030
Raymond Hettingere8364232009-02-02 22:55:09 +000031- Issue 1242657: the __len__() and __length_hint__() calls in several tools
32 were suppressing all exceptions. These include list() and bytearray().
33
Mark Dickinson1124e712009-01-28 21:25:58 +000034- Issue #4707: round(x, n) now returns an integer if x is an integer.
35 Previously it returned a float.
36
Antoine Pitroub52ec782009-01-25 16:34:23 +000037- Issue #4753: By enabling a configure option named '--with-computed-gotos'
38 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
39 evaluation loop is compiled with a new dispatch mechanism which gives
40 speedups of up to 20%, depending on the system, on various benchmarks.
41
Antoine Pitrou81fabdb2009-01-22 10:11:36 +000042- Issue #4874: Most builtin decoders now reject unicode input.
43
Mark Dickinson9ffc0202009-01-20 20:45:53 +000044- Issue #4842: Don't allow trailing 'L' when constructing an integer
45 from a string.
46
Benjamin Peterson05e782f2009-01-19 15:15:02 +000047- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
48
Antoine Pitroue4bc7f62009-01-17 21:06:43 +000049- Issue #4838: When a module is deallocated, free the memory backing the
50 optional module state data.
51
Mark Dickinson8055afd2009-01-17 10:04:45 +000052- Issue #4910: Rename nb_long slot to nb_reserved, and change its
53 type to (void *).
54
Antoine Pitrou8d4e5052009-01-13 22:59:11 +000055- Issue #4935: The overflow checking code in the expandtabs() method common
56 to str, bytes and bytearray could be optimized away by the compiler, letting
57 the interpreter segfault instead of raising an error.
58
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +000059- Issue #3720: Fix a crash when an iterator modifies its class and removes its
60 __next__ method.
61
Mark Dickinsone5e298f2009-01-12 20:49:19 +000062- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
63 function no longer attempt to call the __long__ slot to convert an object
64 to an integer. Only the __int__ and __trunc__ slots are examined.
65
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +000066- Issue #4893: Use NT threading on CE.
67
Martin v. Löwisec59d042009-01-12 07:59:10 +000068- Issue #4915: Port sysmodule to Windows CE.
69
Antoine Pitrouab868312009-01-10 15:40:25 +000070- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
71 common cases are optimized thanks to a dedicated fast path and a moderate
72 amount of loop unrolling.
73
Antoine Pitrou14b78f52009-01-09 22:27:08 +000074- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
75 collecting the oldest generation) so that allocating lots of objects without
76 destroying them does not show quadratic performance. Based on a proposal by
77 Martin von Löwis at
78 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
79
Vinay Sajip6268cbc2009-01-21 00:19:28 +000080- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +000081 having been closed (for instance, a read() call could return some
82 previously buffered data). Patch by Dmitry Vasiliev.
83
Antoine Pitrou05608432009-01-09 18:53:14 +000084- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
85 flag to work properly. Furthermore, when specifying -u, the text stdout
86 and stderr streams have line-by-line buffering enabled (the default being
87 to buffer arbitrary chunks of data).
88
Raymond Hettinger35631532009-01-09 03:58:09 +000089- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
90 instead of ints (reducing its size from 4 to 8 times thereby reducing
91 Python's overall memory).
92
Antoine Pitroud35cbf62009-01-06 19:02:24 +000093- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
94 an existing .py counterpart, override the co_filename attributes of all
95 code objects if the original filename is obsolete (which can happen if the
96 file has been renamed, moved, or if it is accessed through different paths).
97 Patch by Ziga Seilnacht and Jean-Paul Calderone.
98
Antoine Pitrouc3b39242009-01-03 16:59:18 +000099- Issue #4580: Fix slicing of memoryviews when the item size is greater than
100 one byte. Also fixes the meaning of len() so that it returns the number of
101 items, rather than the size in bytes.
102
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000103- Issue #4075: Use OutputDebugStringW in Py_FatalError.
104
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000105- Issue #4747: When the terminal does not use utf-8, executing a script with
106 non-ascii characters in its name could fail with a "SyntaxError: None" error.
107
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000108- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000109 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000110
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000111- Issue #3680: Reference cycles created through a dict, set or deque iterator
112 did not get collected.
113
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000114- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
115 where the tp_hash and tp_dict slots are both NULL.
116
Georg Brandlccc47b62008-12-28 11:44:14 +0000117- Issue #4759: None is now allowed as the first argument of
118 bytearray.translate(). It was always allowed for bytes.translate().
119
Skip Montanaro80072cb2008-12-23 03:51:14 +0000120- Added test case to ensure attempts to read from a file opened for writing
121 fail.
122
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000123- Issue #3106: Speedup some comparisons (str/str and int/int).
124
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000125- Issue #2183: Simplify and optimize bytecode for list, dict and set
126 comprehensions. Original patch for list comprehensions by Neal Norwitz.
127
Antoine Pitrou621601a2008-12-17 23:18:19 +0000128- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
129 print elapsed times, not only when some objects are uncollectable /
130 unreachable. Original patch by Neil Schemenauer.
131
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000132- Issue #3439: Add a bit_length method to int.
133
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000134- Issue #2173: When getting device encoding, check that return value of
135 nl_langinfo is not the empty string. This was causing silent build
136 failures on OS X.
137
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000138- Issue #4597: Fixed several opcodes that weren't always propagating
139 exceptions.
140
141- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000142 context manager returns a value that cannot be converted to a bool.
143
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000144- Issue #4445: Replace "sizeof(PyBytesObject)" with
145 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
146 bytes instances. On a typical machine this saves 3 bytes of memory
147 (on average) per allocation of a bytes instance.
148
Christian Heimesa872de52008-12-05 08:26:55 +0000149- Issue #4533: File read operation was dreadfully slow due to a slowly
150 growing read buffer. Fixed by using the same growth rate algorithm as
151 Python 2.x.
152
Antoine Pitrou5504e892008-12-06 21:27:53 +0000153- Issue #4509: Various issues surrounding resize of bytearray objects to
154 which there are buffer exports (e.g. memoryview instances).
155
Georg Brandlf9734072008-12-07 15:30:06 +0000156- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
157 method on file objects with closefd=False. The file descriptor is still
158 kept open but the file object behaves like a closed file. The ``FileIO``
159 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000160
Antoine Pitroubc420402008-12-07 20:14:49 +0000161- Issue #4569: Interpreter crash when mutating a memoryview with an item size
162 larger than 1.
163

170
Mark Dickinsonc28ad272009-02-12 17:58:36 +0000171- Issue #4998: The memory saving effect of __slots__ had been lost on Fractions
172 which inherited from numbers.py which did not have __slots__ defined. The
