12Core and Builtins
13-----------------
14
Benjamin Peterson87618552009-02-08 15:00:52 +000015- Issue #5182: Removed memoryview.__str__.
16
Mark Dickinsonc008a172009-02-01 13:59:22 +000017- Issue #1717: Removed builtin cmp() function, dropped tp_compare
18 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +000019 the type definition cmpfunc. The tp_compare slot has been renamed
20 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +000021
Raymond Hettingere8364232009-02-02 22:55:09 +000022- Issue 1242657: the __len__() and __length_hint__() calls in several tools
23 were suppressing all exceptions. These include list() and bytearray().
24
Mark Dickinson1124e712009-01-28 21:25:58 +000025- Issue #4707: round(x, n) now returns an integer if x is an integer.
26 Previously it returned a float.
27
Antoine Pitroub52ec782009-01-25 16:34:23 +000028- Issue #4753: By enabling a configure option named '--with-computed-gotos'
29 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
30 evaluation loop is compiled with a new dispatch mechanism which gives
31 speedups of up to 20%, depending on the system, on various benchmarks.
32
Antoine Pitrou81fabdb2009-01-22 10:11:36 +000033- Issue #4874: Most builtin decoders now reject unicode input.
34
Mark Dickinson9ffc0202009-01-20 20:45:53 +000035- Issue #4842: Don't allow trailing 'L' when constructing an integer
36 from a string.
37
Benjamin Peterson05e782f2009-01-19 15:15:02 +000038- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
39
Antoine Pitroue4bc7f62009-01-17 21:06:43 +000040- Issue #4838: When a module is deallocated, free the memory backing the
41 optional module state data.
42
Mark Dickinson8055afd2009-01-17 10:04:45 +000043- Issue #4910: Rename nb_long slot to nb_reserved, and change its
44 type to (void *).
45
Antoine Pitrou8d4e5052009-01-13 22:59:11 +000046- Issue #4935: The overflow checking code in the expandtabs() method common
47 to str, bytes and bytearray could be optimized away by the compiler, letting
48 the interpreter segfault instead of raising an error.
49
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +000050- Issue #3720: Fix a crash when an iterator modifies its class and removes its
51 __next__ method.
52
Mark Dickinsone5e298f2009-01-12 20:49:19 +000053- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
54 function no longer attempt to call the __long__ slot to convert an object
55 to an integer. Only the __int__ and __trunc__ slots are examined.
56
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +000057- Issue #4893: Use NT threading on CE.
58
Martin v. Löwisec59d042009-01-12 07:59:10 +000059- Issue #4915: Port sysmodule to Windows CE.
60
Antoine Pitrouab868312009-01-10 15:40:25 +000061- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
62 common cases are optimized thanks to a dedicated fast path and a moderate
63 amount of loop unrolling.
64
Antoine Pitrou14b78f52009-01-09 22:27:08 +000065- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
66 collecting the oldest generation) so that allocating lots of objects without
67 destroying them does not show quadratic performance. Based on a proposal by
68 Martin von Löwis at
69 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
70
Vinay Sajip6268cbc2009-01-21 00:19:28 +000071- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +000072 having been closed (for instance, a read() call could return some
73 previously buffered data). Patch by Dmitry Vasiliev.
74
Antoine Pitrou05608432009-01-09 18:53:14 +000075- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
76 flag to work properly. Furthermore, when specifying -u, the text stdout
77 and stderr streams have line-by-line buffering enabled (the default being
78 to buffer arbitrary chunks of data).
79
Raymond Hettinger35631532009-01-09 03:58:09 +000080- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
81 instead of ints (reducing its size from 4 to 8 times thereby reducing
82 Python's overall memory).
83
Antoine Pitroud35cbf62009-01-06 19:02:24 +000084- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
85 an existing .py counterpart, override the co_filename attributes of all
86 code objects if the original filename is obsolete (which can happen if the
87 file has been renamed, moved, or if it is accessed through different paths).
88 Patch by Ziga Seilnacht and Jean-Paul Calderone.
89
Antoine Pitrouc3b39242009-01-03 16:59:18 +000090- Issue #4580: Fix slicing of memoryviews when the item size is greater than
91 one byte. Also fixes the meaning of len() so that it returns the number of
92 items, rather than the size in bytes.
93
Martin v. Löwis5c88d812009-01-02 20:47:48 +000094- Issue #4075: Use OutputDebugStringW in Py_FatalError.
95
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +000096- Issue #4747: When the terminal does not use utf-8, executing a script with
97 non-ascii characters in its name could fail with a "SyntaxError: None" error.
98
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +000099- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000100 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000101
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000102- Issue #3680: Reference cycles created through a dict, set or deque iterator
103 did not get collected.
104
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000105- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
106 where the tp_hash and tp_dict slots are both NULL.
107
Georg Brandlccc47b62008-12-28 11:44:14 +0000108- Issue #4759: None is now allowed as the first argument of
109 bytearray.translate(). It was always allowed for bytes.translate().
110
Skip Montanaro80072cb2008-12-23 03:51:14 +0000111- Added test case to ensure attempts to read from a file opened for writing
112 fail.
113
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000114- Issue #3106: Speedup some comparisons (str/str and int/int).
115
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000116- Issue #2183: Simplify and optimize bytecode for list, dict and set
117 comprehensions. Original patch for list comprehensions by Neal Norwitz.
118
Antoine Pitrou621601a2008-12-17 23:18:19 +0000119- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
120 print elapsed times, not only when some objects are uncollectable /
121 unreachable. Original patch by Neil Schemenauer.
122
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000123- Issue #3439: Add a bit_length method to int.
124
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000125- Issue #2173: When getting device encoding, check that return value of
126 nl_langinfo is not the empty string. This was causing silent build
127 failures on OS X.
128
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000129- Issue #4597: Fixed several opcodes that weren't always propagating
130 exceptions.
131
132- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000133 context manager returns a value that cannot be converted to a bool.
134
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000135- Issue #4445: Replace "sizeof(PyBytesObject)" with
136 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
137 bytes instances. On a typical machine this saves 3 bytes of memory
138 (on average) per allocation of a bytes instance.
139
Christian Heimesa872de52008-12-05 08:26:55 +0000140- Issue #4533: File read operation was dreadfully slow due to a slowly
141 growing read buffer. Fixed by using the same growth rate algorithm as
142 Python 2.x.
143
Antoine Pitrou5504e892008-12-06 21:27:53 +0000144- Issue #4509: Various issues surrounding resize of bytearray objects to
145 which there are buffer exports (e.g. memoryview instances).
146
Georg Brandlf9734072008-12-07 15:30:06 +0000147- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
148 method on file objects with closefd=False. The file descriptor is still
149 kept open but the file object behaves like a closed file. The ``FileIO``
150 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000151
Antoine Pitroubc420402008-12-07 20:14:49 +0000152- Issue #4569: Interpreter crash when mutating a memoryview with an item size
153 larger than 1.
154

161 public documented method ``ZipImporter.get_filename()``.
162
Nick Coghlan3f48ae32009-02-08 01:58:26 +0000163- Issue #4195: The ``runpy`` module (and the ``-m`` switch) now support

169 not be used again (this requires Tcl/Tk 8.3.1), also fix a memory leak in
170 Tkapp_Call when calling from a thread different than the one that created
171 the Tcl interpreter. Patch by Robert Hancock.
172
Eric Smith0e5b5622009-02-06 01:32:42 +0000173- Issue #4285: Change sys.version_info to be a named tuple. Patch by

190 items being passed through ord().
191
Antoine Pitrou0dcc3cd2009-01-29 20:26:59 +0000192- Issue #2047: shutil.move() could believe that its destination path was
193 inside its source path if it began with the same letters (e.g. "src" vs.
194 "src.new").
195

201
Raymond Hettinger0f055172009-01-27 10:06:09 +0000202- Issue 5021: doctest.testfile() did not create __name__ and
203 collections.namedtuple() relied on __name__ being defined.

231 be disabled, and not compiled.
232
Antoine Pitrou08838b62009-01-21 00:55:13 +0000233- Issue #5008: When a file is opened in append mode with the new IO library,
234 do an explicit seek to the end of file (so that e.g. tell() returns the
235 file size rather than 0). This is consistent with the behaviour of the
236 traditional 2.x file object.
237
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000238- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

267 rather than delaying the close by waiting for garbage collection to do it.
268
Raymond Hettingerb8baf632009-01-14 02:20:07 +0000269- Issue #1696199: Add collections.Counter() for rapid and convenient
270 counting.
271
Antoine Pitrou308705e2009-01-10 16:22:51 +0000272- Issue #3860: GzipFile and BZ2File now support the context manager protocol.

301 did unnecessary work in the common case where no key function was specified.
302
Georg Brandlb1441c72009-01-03 22:33:39 +0000303- Issue #4795: inspect.isgeneratorfunction() returns False instead of None when
