12Core and Builtins
13-----------------
14
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +000015- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
16 returns a non-number type.
17
Benjamin Peterson87618552009-02-08 15:00:52 +000018- Issue #5182: Removed memoryview.__str__.
19
Mark Dickinsonc008a172009-02-01 13:59:22 +000020- Issue #1717: Removed builtin cmp() function, dropped tp_compare
21 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +000022 the type definition cmpfunc. The tp_compare slot has been renamed
23 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +000024
Raymond Hettingere8364232009-02-02 22:55:09 +000025- Issue 1242657: the __len__() and __length_hint__() calls in several tools
26 were suppressing all exceptions. These include list() and bytearray().
27
Mark Dickinson1124e712009-01-28 21:25:58 +000028- Issue #4707: round(x, n) now returns an integer if x is an integer.
29 Previously it returned a float.
30
Antoine Pitroub52ec782009-01-25 16:34:23 +000031- Issue #4753: By enabling a configure option named '--with-computed-gotos'
32 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
33 evaluation loop is compiled with a new dispatch mechanism which gives
34 speedups of up to 20%, depending on the system, on various benchmarks.
35
Antoine Pitrou81fabdb2009-01-22 10:11:36 +000036- Issue #4874: Most builtin decoders now reject unicode input.
37
Mark Dickinson9ffc0202009-01-20 20:45:53 +000038- Issue #4842: Don't allow trailing 'L' when constructing an integer
39 from a string.
40
Benjamin Peterson05e782f2009-01-19 15:15:02 +000041- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
42
Antoine Pitroue4bc7f62009-01-17 21:06:43 +000043- Issue #4838: When a module is deallocated, free the memory backing the
44 optional module state data.
45
Mark Dickinson8055afd2009-01-17 10:04:45 +000046- Issue #4910: Rename nb_long slot to nb_reserved, and change its
47 type to (void *).
48
Antoine Pitrou8d4e5052009-01-13 22:59:11 +000049- Issue #4935: The overflow checking code in the expandtabs() method common
50 to str, bytes and bytearray could be optimized away by the compiler, letting
51 the interpreter segfault instead of raising an error.
52
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +000053- Issue #3720: Fix a crash when an iterator modifies its class and removes its
54 __next__ method.
55
Mark Dickinsone5e298f2009-01-12 20:49:19 +000056- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
57 function no longer attempt to call the __long__ slot to convert an object
58 to an integer. Only the __int__ and __trunc__ slots are examined.
59
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +000060- Issue #4893: Use NT threading on CE.
61
Martin v. Löwisec59d042009-01-12 07:59:10 +000062- Issue #4915: Port sysmodule to Windows CE.
63
Antoine Pitrouab868312009-01-10 15:40:25 +000064- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
65 common cases are optimized thanks to a dedicated fast path and a moderate
66 amount of loop unrolling.
67
Antoine Pitrou14b78f52009-01-09 22:27:08 +000068- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
69 collecting the oldest generation) so that allocating lots of objects without
70 destroying them does not show quadratic performance. Based on a proposal by
71 Martin von Löwis at
72 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
73
Vinay Sajip6268cbc2009-01-21 00:19:28 +000074- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +000075 having been closed (for instance, a read() call could return some
76 previously buffered data). Patch by Dmitry Vasiliev.
77
Antoine Pitrou05608432009-01-09 18:53:14 +000078- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
79 flag to work properly. Furthermore, when specifying -u, the text stdout
80 and stderr streams have line-by-line buffering enabled (the default being
81 to buffer arbitrary chunks of data).
82
Raymond Hettinger35631532009-01-09 03:58:09 +000083- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
84 instead of ints (reducing its size from 4 to 8 times thereby reducing
85 Python's overall memory).
86
Antoine Pitroud35cbf62009-01-06 19:02:24 +000087- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
88 an existing .py counterpart, override the co_filename attributes of all
89 code objects if the original filename is obsolete (which can happen if the
90 file has been renamed, moved, or if it is accessed through different paths).
91 Patch by Ziga Seilnacht and Jean-Paul Calderone.
92
Antoine Pitrouc3b39242009-01-03 16:59:18 +000093- Issue #4580: Fix slicing of memoryviews when the item size is greater than
94 one byte. Also fixes the meaning of len() so that it returns the number of
95 items, rather than the size in bytes.
96
Martin v. Löwis5c88d812009-01-02 20:47:48 +000097- Issue #4075: Use OutputDebugStringW in Py_FatalError.
98
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +000099- Issue #4747: When the terminal does not use utf-8, executing a script with
100 non-ascii characters in its name could fail with a "SyntaxError: None" error.
101
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000102- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000103 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000104
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000105- Issue #3680: Reference cycles created through a dict, set or deque iterator
106 did not get collected.
107
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000108- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
109 where the tp_hash and tp_dict slots are both NULL.
110
Georg Brandlccc47b62008-12-28 11:44:14 +0000111- Issue #4759: None is now allowed as the first argument of
112 bytearray.translate(). It was always allowed for bytes.translate().
113
Skip Montanaro80072cb2008-12-23 03:51:14 +0000114- Added test case to ensure attempts to read from a file opened for writing
115 fail.
116
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000117- Issue #3106: Speedup some comparisons (str/str and int/int).
118
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000119- Issue #2183: Simplify and optimize bytecode for list, dict and set
120 comprehensions. Original patch for list comprehensions by Neal Norwitz.
121
Antoine Pitrou621601a2008-12-17 23:18:19 +0000122- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
123 print elapsed times, not only when some objects are uncollectable /
124 unreachable. Original patch by Neil Schemenauer.
125
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000126- Issue #3439: Add a bit_length method to int.
127
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000128- Issue #2173: When getting device encoding, check that return value of
129 nl_langinfo is not the empty string. This was causing silent build
130 failures on OS X.
131
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000132- Issue #4597: Fixed several opcodes that weren't always propagating
133 exceptions.
134
135- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000136 context manager returns a value that cannot be converted to a bool.
137
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000138- Issue #4445: Replace "sizeof(PyBytesObject)" with
139 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
140 bytes instances. On a typical machine this saves 3 bytes of memory
141 (on average) per allocation of a bytes instance.
142
Christian Heimesa872de52008-12-05 08:26:55 +0000143- Issue #4533: File read operation was dreadfully slow due to a slowly
144 growing read buffer. Fixed by using the same growth rate algorithm as
145 Python 2.x.
146
Antoine Pitrou5504e892008-12-06 21:27:53 +0000147- Issue #4509: Various issues surrounding resize of bytearray objects to
148 which there are buffer exports (e.g. memoryview instances).
149
Georg Brandlf9734072008-12-07 15:30:06 +0000150- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
151 method on file objects with closefd=False. The file descriptor is still
152 kept open but the file object behaves like a closed file. The ``FileIO``
153 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000154
Antoine Pitroubc420402008-12-07 20:14:49 +0000155- Issue #4569: Interpreter crash when mutating a memoryview with an item size
156 larger than 1.

239 do an explicit seek to the end of file (so that e.g. tell() returns the
240 file size rather than 0). This is consistent with the behaviour of the
241 traditional 2.x file object.
242
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000243- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

272 rather than delaying the close by waiting for garbage collection to do it.
273
Raymond Hettingerb8baf632009-01-14 02:20:07 +0000274- Issue #1696199: Add collections.Counter() for rapid and convenient
275 counting.
276
