Barry Warsawd8ccd1c2008-11-21 15:13:37 +000011
12Core and Builtins
13-----------------
14
Mark Dickinson1124e712009-01-28 21:25:58 +000015- Issue #4707: round(x, n) now returns an integer if x is an integer.
16 Previously it returned a float.
17
Antoine Pitroub52ec782009-01-25 16:34:23 +000018- Issue #4753: By enabling a configure option named '--with-computed-gotos'
19 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
20 evaluation loop is compiled with a new dispatch mechanism which gives
21 speedups of up to 20%, depending on the system, on various benchmarks.
22
Antoine Pitrou81fabdb2009-01-22 10:11:36 +000023- Issue #4874: Most builtin decoders now reject unicode input.
24
Mark Dickinson9ffc0202009-01-20 20:45:53 +000025- Issue #4842: Don't allow trailing 'L' when constructing an integer
26 from a string.
27
Benjamin Peterson05e782f2009-01-19 15:15:02 +000028- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
29
Antoine Pitroue4bc7f62009-01-17 21:06:43 +000030- Issue #4838: When a module is deallocated, free the memory backing the
31 optional module state data.
32
Mark Dickinson8055afd2009-01-17 10:04:45 +000033- Issue #4910: Rename nb_long slot to nb_reserved, and change its
34 type to (void *).
35
Antoine Pitrou8d4e5052009-01-13 22:59:11 +000036- Issue #4935: The overflow checking code in the expandtabs() method common
37 to str, bytes and bytearray could be optimized away by the compiler, letting
38 the interpreter segfault instead of raising an error.
39
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +000040- Issue #3720: Fix a crash when an iterator modifies its class and removes its
41 __next__ method.
42
Mark Dickinsone5e298f2009-01-12 20:49:19 +000043- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
44 function no longer attempt to call the __long__ slot to convert an object
45 to an integer. Only the __int__ and __trunc__ slots are examined.
46
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +000047- Issue #4893: Use NT threading on CE.
48
Martin v. Löwisec59d042009-01-12 07:59:10 +000049- Issue #4915: Port sysmodule to Windows CE.
50
Antoine Pitrouab868312009-01-10 15:40:25 +000051- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
52 common cases are optimized thanks to a dedicated fast path and a moderate
53 amount of loop unrolling.
54
Antoine Pitrou14b78f52009-01-09 22:27:08 +000055- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
56 collecting the oldest generation) so that allocating lots of objects without
57 destroying them does not show quadratic performance. Based on a proposal by
58 Martin von Löwis at
59 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
60
Vinay Sajip6268cbc2009-01-21 00:19:28 +000061- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +000062 having been closed (for instance, a read() call could return some
63 previously buffered data). Patch by Dmitry Vasiliev.
64
Antoine Pitrou05608432009-01-09 18:53:14 +000065- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
66 flag to work properly. Furthermore, when specifying -u, the text stdout
67 and stderr streams have line-by-line buffering enabled (the default being
68 to buffer arbitrary chunks of data).
69
Raymond Hettinger35631532009-01-09 03:58:09 +000070- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
71 instead of ints (reducing its size from 4 to 8 times thereby reducing
72 Python's overall memory).
73
Antoine Pitroud35cbf62009-01-06 19:02:24 +000074- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
75 an existing .py counterpart, override the co_filename attributes of all
76 code objects if the original filename is obsolete (which can happen if the
77 file has been renamed, moved, or if it is accessed through different paths).
78 Patch by Ziga Seilnacht and Jean-Paul Calderone.
79
Antoine Pitrouc3b39242009-01-03 16:59:18 +000080- Issue #4580: Fix slicing of memoryviews when the item size is greater than
81 one byte. Also fixes the meaning of len() so that it returns the number of
82 items, rather than the size in bytes.
83
Martin v. Löwis5c88d812009-01-02 20:47:48 +000084- Issue #4075: Use OutputDebugStringW in Py_FatalError.
85
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +000086- Issue #4747: When the terminal does not use utf-8, executing a script with
87 non-ascii characters in its name could fail with a "SyntaxError: None" error.
88
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +000089- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +000090 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +000091
Antoine Pitrou7ddda782009-01-01 15:35:33 +000092- Issue #3680: Reference cycles created through a dict, set or deque iterator
93 did not get collected.
94
Nick Coghlanf1f2f682008-12-30 07:29:12 +000095- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
96 where the tp_hash and tp_dict slots are both NULL.
97
Georg Brandlccc47b62008-12-28 11:44:14 +000098- Issue #4759: None is now allowed as the first argument of
99 bytearray.translate(). It was always allowed for bytes.translate().
100
Skip Montanaro80072cb2008-12-23 03:51:14 +0000101- Added test case to ensure attempts to read from a file opened for writing
102 fail.
103
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000104- Issue #3106: Speedup some comparisons (str/str and int/int).
105
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000106- Issue #2183: Simplify and optimize bytecode for list, dict and set
107 comprehensions. Original patch for list comprehensions by Neal Norwitz.
108
Antoine Pitrou621601a2008-12-17 23:18:19 +0000109- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
110 print elapsed times, not only when some objects are uncollectable /
111 unreachable. Original patch by Neil Schemenauer.
112
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000113- Issue #3439: Add a bit_length method to int.
114
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000115- Issue #2173: When getting device encoding, check that return value of
116 nl_langinfo is not the empty string. This was causing silent build
117 failures on OS X.
118
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000119- Issue #4597: Fixed several opcodes that weren't always propagating
120 exceptions.
121
122- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000123 context manager returns a value that cannot be converted to a bool.
124
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000125- Issue #4445: Replace "sizeof(PyBytesObject)" with
126 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
127 bytes instances. On a typical machine this saves 3 bytes of memory
128 (on average) per allocation of a bytes instance.
129
Christian Heimesa872de52008-12-05 08:26:55 +0000130- Issue #4533: File read operation was dreadfully slow due to a slowly
131 growing read buffer. Fixed by using the same growth rate algorithm as
132 Python 2.x.
133
Antoine Pitrou5504e892008-12-06 21:27:53 +0000134- Issue #4509: Various issues surrounding resize of bytearray objects to
135 which there are buffer exports (e.g. memoryview instances).
136
Georg Brandlf9734072008-12-07 15:30:06 +0000137- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
138 method on file objects with closefd=False. The file descriptor is still
139 kept open but the file object behaves like a closed file. The ``FileIO``
140 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000141
Antoine Pitroubc420402008-12-07 20:14:49 +0000142- Issue #4569: Interpreter crash when mutating a memoryview with an item size
143 larger than 1.
144

148-------
149
Antoine Pitrou0dcc3cd2009-01-29 20:26:59 +0000150- Issue #2047: shutil.move() could believe that its destination path was
151 inside its source path if it began with the same letters (e.g. "src" vs.
152 "src.new").
153
Guilherme Polo5f238482009-01-28 14:41:10 +0000154- Added the ttk module. See issue #2983: Ttk support for Tkinter.
155
Raymond Hettinger89e12962009-01-26 02:09:03 +0000156- Removed isSequenceType(), isMappingType, and isNumberType() from the
157 operator module; use the abstract base classes instead. Also removed
158 the repeat() function; use mul() instead.
159
Raymond Hettinger0f055172009-01-27 10:06:09 +0000160- Issue 5021: doctest.testfile() did not create __name__ and
161 collections.namedtuple() relied on __name__ being defined.
162
163- Backport importlib from Python 3.1. Only the import_module() function has
164 been backported to help facilitate transitions from 2.7 to 3.1.
165
Tarek Ziadé0302cf52009-01-26 17:23:20 +0000166- Issue #1885: distutils. When running sdist with --formats=tar,gztar
167 the tar file was overriden by the gztar one.
168
Tarek Ziadé4d4456f2009-01-25 18:27:45 +0000169- Issue #4863: distutils.mwerkscompiler has been removed.

Raymond Hettingerd07d9392009-01-27 04:20:44 +0000171- Added a new itertools functions: combinations_with_replacement()
172 and compress().
Raymond Hettinger6b3b0fc2009-01-26 02:56:58 +0000173
Jesse Noller41faa542009-01-25 03:45:53 +0000174- Fix and properly document the multiprocessing module's logging
175 support, expose the internal levels and provide proper usage
176 examples.
177
Mark Dickinsoncddcf442009-01-24 21:46:33 +0000178- Issue #1672332: fix unpickling of subnormal floats, which was
179 producing a ValueError on some platforms.
180
Martin v. Löwisacbf4612009-01-24 16:19:45 +0000181- Issue #3881: Help Tcl to load even when started through the

188 --without-threads argument. When this occurs, _multiprocessing will
189 be disabled, and not compiled.
190
Antoine Pitrou08838b62009-01-21 00:55:13 +0000191- Issue #5008: When a file is opened in append mode with the new IO library,
192 do an explicit seek to the end of file (so that e.g. tell() returns the
193 file size rather than 0). This is consistent with the behaviour of the
194 traditional 2.x file object.
195
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000196- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

211 without defaults.
212
Jesse Noller6214edd2009-01-19 16:23:53 +0000213- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
214 for *nix machines for negative handles and large int handles. Without this check
215 it is possible to segfault the interpreter.
216
Jesse Nollerb0516a62009-01-18 03:11:38 +0000217- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue

224 appropriately when it is being used via socket.makefile() objects
225 rather than delaying the close by waiting for garbage collection to do it.
226
Raymond Hettingerb8baf632009-01-14 02:20:07 +0000227- Issue #1696199: Add collections.Counter() for rapid and convenient
228 counting.
229
Antoine Pitrou308705e2009-01-10 16:22:51 +0000230- Issue #3860: GzipFile and BZ2File now support the context manager protocol.

236 the timestamp in the gzip stream. The default value remains the current time.
237 The information can be used by e.g. gunzip when decompressing. Patch by
238 Jacques Frechet.

298 perform IO operations based on __file__). Original patch by
299 Alexander Belopolsky.
300
301- Issues #4082 and #4512: Add runpy support to zipimport in a manner that
302 allows backporting to maintenance branches. Original patch by
