Benjamin Peterson8f76b492009-04-03 22:22:42 +000036- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
37
Benjamin Peterson7fe98532009-04-02 00:33:55 +000038- Issue #5499: The 'c' code for argument parsing functions now only accepts a
39 byte, and the 'C' code only accepts a unicode character.
40
Brett Cannon0759dd62009-04-01 18:13:07 +000041- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
42
Georg Brandlab6f2f62009-03-31 04:16:10 +000043- Fix a segfault when running test_exceptions with coverage, caused by
44 insufficient checks in accessors of Exception.__context__.
45
Guido van Rossum0ad59d42009-03-30 22:01:35 +000046- Issue #5604: non-ASCII characters in module name passed to
47 imp.find_module() were converted to UTF-8 while the path is
48 converted to the default filesystem encoding, causing nonsense.
49
Benjamin Peterson09832742009-03-26 17:15:46 +000050- Issue #5126: str.isprintable() returned False for space characters.
51
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +000052- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
53 the end sys.path, for compatibility with the system install of Python.
54
Antoine Pitrou3a652b12009-03-23 18:52:06 +000055- Issue #4688: Add a heuristic so that tuples and dicts containing only
56 untrackable objects are not tracked by the garbage collector. This can
57 reduce the size of collections and therefore the garbage collection overhead
58 on long-running programs, depending on their particular use of datatypes.
59
Mark Dickinson17e4fdd2009-03-23 18:44:57 +000060- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

65 2**15 for the internal representation of integers, for performance
66 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
67 --enable-big-digits option to configure, which overrides the
68 default. Add sys.int_info structseq to provide information about
69 the internal format.
70

72 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
73 and sizeof(Py_UNICODE) == 2.
74
Eric Smith8ec90442009-03-14 12:29:34 +000075- Issue #5237: Allow auto-numbered fields in str.format(). For

77
Antoine Pitrou652e7072009-03-13 19:25:20 +000078- Issue #5392: when a very low recursion limit was set, the interpreter would
79 abort with a fatal error after the recursion limit was hit twice.
80
Matthias Klose042f1332009-04-04 14:32:42 +000081- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

127
Lars Gustäbel42e00912009-03-22 20:34:29 +0000128- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
129 forever on incomplete input. That caused tarfile.open() to hang when used
130 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
131 partial bzip2 compressed data.
132
Mark Dickinson79f52032009-03-17 23:12:51 +0000133- Issue #2110: Add support for thousands separator and 'n' type

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000194- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000195 were suppressing all exceptions. These include list() and bytearray().

201 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
202 evaluation loop is compiled with a new dispatch mechanism which gives
203 speedups of up to 20%, depending on the system, on various benchmarks.

216 type to (void *).
217
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000218- Issue #4935: The overflow checking code in the expandtabs() method common
219 to str, bytes and bytearray could be optimized away by the compiler, letting
220 the interpreter segfault instead of raising an error.
221
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000222- Issue #3720: Fix a crash when an iterator modifies its class and removes its

234 common cases are optimized thanks to a dedicated fast path and a moderate
235 amount of loop unrolling.
236
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000237- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
238 collecting the oldest generation) so that allocating lots of objects without
239 destroying them does not show quadratic performance. Based on a proposal by
240 Martin von Löwis at
241 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
242
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000243- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000244 having been closed (for instance, a read() call could return some
245 previously buffered data). Patch by Dmitry Vasiliev.

248 flag to work properly. Furthermore, when specifying -u, the text stdout
249 and stderr streams have line-by-line buffering enabled (the default being
250 to buffer arbitrary chunks of data).
251
Raymond Hettinger35631532009-01-09 03:58:09 +0000252- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
253 instead of ints (reducing its size from 4 to 8 times thereby reducing
254 Python's overall memory).
255
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000256- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
257 an existing .py counterpart, override the co_filename attributes of all
258 code objects if the original filename is obsolete (which can happen if the
259 file has been renamed, moved, or if it is accessed through different paths).
260 Patch by Ziga Seilnacht and Jean-Paul Calderone.
261
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000262- Issue #4580: Fix slicing of memoryviews when the item size is greater than
263 one byte. Also fixes the meaning of len() so that it returns the number of
264 items, rather than the size in bytes.
265
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000266- Issue #4075: Use OutputDebugStringW in Py_FatalError.
267
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000268- Issue #4747: When the terminal does not use utf-8, executing a script with
269 non-ascii characters in its name could fail with a "SyntaxError: None" error.

276
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000277- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
278 where the tp_hash and tp_dict slots are both NULL.
279
Georg Brandlccc47b62008-12-28 11:44:14 +0000280- Issue #4759: None is now allowed as the first argument of
281 bytearray.translate(). It was always allowed for bytes.translate().
282
Skip Montanaro80072cb2008-12-23 03:51:14 +0000283- Added test case to ensure attempts to read from a file opened for writing
284 fail.

321 kept open but the file object behaves like a closed file. The ``FileIO``
322 object also got a new readonly attribute ``closefd``.
