12Core and Builtins
13-----------------
14
Mark Dickinsonc008a172009-02-01 13:59:22 +000015- Issue #1717: Removed builtin cmp() function, dropped tp_compare
16 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +000017 the type definition cmpfunc. The tp_compare slot has been renamed
18 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +000019
Raymond Hettingere8364232009-02-02 22:55:09 +000020- Issue 1242657: the __len__() and __length_hint__() calls in several tools
21 were suppressing all exceptions. These include list() and bytearray().
22
Mark Dickinson1124e712009-01-28 21:25:58 +000023- Issue #4707: round(x, n) now returns an integer if x is an integer.
24 Previously it returned a float.
25
Antoine Pitroub52ec782009-01-25 16:34:23 +000026- Issue #4753: By enabling a configure option named '--with-computed-gotos'
27 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
28 evaluation loop is compiled with a new dispatch mechanism which gives
29 speedups of up to 20%, depending on the system, on various benchmarks.
30
Antoine Pitrou81fabdb2009-01-22 10:11:36 +000031- Issue #4874: Most builtin decoders now reject unicode input.
32
Mark Dickinson9ffc0202009-01-20 20:45:53 +000033- Issue #4842: Don't allow trailing 'L' when constructing an integer
34 from a string.
35
Benjamin Peterson05e782f2009-01-19 15:15:02 +000036- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
37
Antoine Pitroue4bc7f62009-01-17 21:06:43 +000038- Issue #4838: When a module is deallocated, free the memory backing the
39 optional module state data.
40
Mark Dickinson8055afd2009-01-17 10:04:45 +000041- Issue #4910: Rename nb_long slot to nb_reserved, and change its
42 type to (void *).
43
Antoine Pitrou8d4e5052009-01-13 22:59:11 +000044- Issue #4935: The overflow checking code in the expandtabs() method common
45 to str, bytes and bytearray could be optimized away by the compiler, letting
46 the interpreter segfault instead of raising an error.
47
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +000048- Issue #3720: Fix a crash when an iterator modifies its class and removes its
49 __next__ method.
50
Mark Dickinsone5e298f2009-01-12 20:49:19 +000051- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
52 function no longer attempt to call the __long__ slot to convert an object
53 to an integer. Only the __int__ and __trunc__ slots are examined.
54
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +000055- Issue #4893: Use NT threading on CE.
56
Martin v. Löwisec59d042009-01-12 07:59:10 +000057- Issue #4915: Port sysmodule to Windows CE.
58
Antoine Pitrouab868312009-01-10 15:40:25 +000059- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
60 common cases are optimized thanks to a dedicated fast path and a moderate
61 amount of loop unrolling.
62
Antoine Pitrou14b78f52009-01-09 22:27:08 +000063- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
64 collecting the oldest generation) so that allocating lots of objects without
65 destroying them does not show quadratic performance. Based on a proposal by
66 Martin von Löwis at
67 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
68
Vinay Sajip6268cbc2009-01-21 00:19:28 +000069- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +000070 having been closed (for instance, a read() call could return some
71 previously buffered data). Patch by Dmitry Vasiliev.
72
Antoine Pitrou05608432009-01-09 18:53:14 +000073- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
74 flag to work properly. Furthermore, when specifying -u, the text stdout
75 and stderr streams have line-by-line buffering enabled (the default being
76 to buffer arbitrary chunks of data).
77
Raymond Hettinger35631532009-01-09 03:58:09 +000078- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
79 instead of ints (reducing its size from 4 to 8 times thereby reducing
80 Python's overall memory).
81
Antoine Pitroud35cbf62009-01-06 19:02:24 +000082- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
83 an existing .py counterpart, override the co_filename attributes of all
84 code objects if the original filename is obsolete (which can happen if the
85 file has been renamed, moved, or if it is accessed through different paths).
86 Patch by Ziga Seilnacht and Jean-Paul Calderone.
87
Antoine Pitrouc3b39242009-01-03 16:59:18 +000088- Issue #4580: Fix slicing of memoryviews when the item size is greater than
89 one byte. Also fixes the meaning of len() so that it returns the number of
90 items, rather than the size in bytes.
91
Martin v. Löwis5c88d812009-01-02 20:47:48 +000092- Issue #4075: Use OutputDebugStringW in Py_FatalError.
93
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +000094- Issue #4747: When the terminal does not use utf-8, executing a script with
95 non-ascii characters in its name could fail with a "SyntaxError: None" error.
96
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +000097- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +000098 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +000099
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000100- Issue #3680: Reference cycles created through a dict, set or deque iterator
101 did not get collected.
102
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000103- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
104 where the tp_hash and tp_dict slots are both NULL.
105
Georg Brandlccc47b62008-12-28 11:44:14 +0000106- Issue #4759: None is now allowed as the first argument of
107 bytearray.translate(). It was always allowed for bytes.translate().
108
Skip Montanaro80072cb2008-12-23 03:51:14 +0000109- Added test case to ensure attempts to read from a file opened for writing
110 fail.
111
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000112- Issue #3106: Speedup some comparisons (str/str and int/int).
113
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000114- Issue #2183: Simplify and optimize bytecode for list, dict and set
115 comprehensions. Original patch for list comprehensions by Neal Norwitz.
116
Antoine Pitrou621601a2008-12-17 23:18:19 +0000117- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
118 print elapsed times, not only when some objects are uncollectable /
119 unreachable. Original patch by Neil Schemenauer.
120
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000121- Issue #3439: Add a bit_length method to int.
122
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000123- Issue #2173: When getting device encoding, check that return value of
124 nl_langinfo is not the empty string. This was causing silent build
125 failures on OS X.
126
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000127- Issue #4597: Fixed several opcodes that weren't always propagating
128 exceptions.
129
130- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000131 context manager returns a value that cannot be converted to a bool.
132
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000133- Issue #4445: Replace "sizeof(PyBytesObject)" with
134 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
135 bytes instances. On a typical machine this saves 3 bytes of memory
136 (on average) per allocation of a bytes instance.
137
Christian Heimesa872de52008-12-05 08:26:55 +0000138- Issue #4533: File read operation was dreadfully slow due to a slowly
139 growing read buffer. Fixed by using the same growth rate algorithm as
140 Python 2.x.
141
Antoine Pitrou5504e892008-12-06 21:27:53 +0000142- Issue #4509: Various issues surrounding resize of bytearray objects to
143 which there are buffer exports (e.g. memoryview instances).
144
Georg Brandlf9734072008-12-07 15:30:06 +0000145- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
146 method on file objects with closefd=False. The file descriptor is still
147 kept open but the file object behaves like a closed file. The ``FileIO``
148 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000149
Antoine Pitroubc420402008-12-07 20:14:49 +0000150- Issue #4569: Interpreter crash when mutating a memoryview with an item size
151 larger than 1.
152
Benjamin Peterson371ccfb2008-12-27 19:03:36 +0000153- Issue #4748: Lambda generators no longer return a value.

159 public documented method ``ZipImporter.get_filename()``.
160
Nick Coghlan3f48ae32009-02-08 01:58:26 +0000161- Issue #4195: The ``runpy`` module (and the ``-m`` switch) now support

167 not be used again (this requires Tcl/Tk 8.3.1), also fix a memory leak in
168 Tkapp_Call when calling from a thread different than the one that created
169 the Tcl interpreter. Patch by Robert Hancock.
170
Eric Smith0e5b5622009-02-06 01:32:42 +0000171- Issue #4285: Change sys.version_info to be a named tuple. Patch by

188 items being passed through ord().
189
Antoine Pitrou0dcc3cd2009-01-29 20:26:59 +0000190- Issue #2047: shutil.move() could believe that its destination path was
191 inside its source path if it began with the same letters (e.g. "src" vs.
192 "src.new").

199
Raymond Hettinger0f055172009-01-27 10:06:09 +0000200- Issue 5021: doctest.testfile() did not create __name__ and
201 collections.namedtuple() relied on __name__ being defined.

229 be disabled, and not compiled.
230
Antoine Pitrou08838b62009-01-21 00:55:13 +0000231- Issue #5008: When a file is opened in append mode with the new IO library,
232 do an explicit seek to the end of file (so that e.g. tell() returns the
233 file size rather than 0). This is consistent with the behaviour of the
234 traditional 2.x file object.
235
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000236- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

264 appropriately when it is being used via socket.makefile() objects
265 rather than delaying the close by waiting for garbage collection to do it.
266
Raymond Hettingerb8baf632009-01-14 02:20:07 +0000267- Issue #1696199: Add collections.Counter() for rapid and convenient
268 counting.
269
Antoine Pitrou308705e2009-01-10 16:22:51 +0000270- Issue #3860: GzipFile and BZ2File now support the context manager protocol.

299 did unnecessary work in the common case where no key function was specified.
300
Georg Brandlb1441c72009-01-03 22:33:39 +0000301- Issue #4795: inspect.isgeneratorfunction() returns False instead of None when
302 the function is not a generator.
303
