Benjamin Peterson8f76b492009-04-03 22:22:42 +000045- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
46
Benjamin Peterson7fe98532009-04-02 00:33:55 +000047- Issue #5499: The 'c' code for argument parsing functions now only accepts a
48 byte, and the 'C' code only accepts a unicode character.
49
Brett Cannon0759dd62009-04-01 18:13:07 +000050- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
51
Georg Brandlab6f2f62009-03-31 04:16:10 +000052- Fix a segfault when running test_exceptions with coverage, caused by
53 insufficient checks in accessors of Exception.__context__.
54
Guido van Rossum0ad59d42009-03-30 22:01:35 +000055- Issue #5604: non-ASCII characters in module name passed to
56 imp.find_module() were converted to UTF-8 while the path is
57 converted to the default filesystem encoding, causing nonsense.
58
Benjamin Peterson09832742009-03-26 17:15:46 +000059- Issue #5126: str.isprintable() returned False for space characters.

Antoine Pitrou3a652b12009-03-23 18:52:06 +000064- Issue #4688: Add a heuristic so that tuples and dicts containing only
65 untrackable objects are not tracked by the garbage collector. This can
66 reduce the size of collections and therefore the garbage collection overhead
67 on long-running programs, depending on their particular use of datatypes.
68
Mark Dickinson17e4fdd2009-03-23 18:44:57 +000069- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

77 default. Add sys.int_info structseq to provide information about
78 the internal format.
79

81 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
82 and sizeof(Py_UNICODE) == 2.
83
Eric Smith8ec90442009-03-14 12:29:34 +000084- Issue #5237: Allow auto-numbered fields in str.format(). For

88 abort with a fatal error after the recursion limit was hit twice.
89
Matthias Klose042f1332009-04-04 14:32:42 +000090- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

128
Benjamin Peterson48e24782009-03-29 13:02:52 +0000129- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().

Lars Gustäbel42e00912009-03-22 20:34:29 +0000137- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
138 forever on incomplete input. That caused tarfile.open() to hang when used
139 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
140 partial bzip2 compressed data.
141
Mark Dickinson79f52032009-03-17 23:12:51 +0000142- Issue #2110: Add support for thousands separator and 'n' type

225 type to (void *).
226
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000227- Issue #4935: The overflow checking code in the expandtabs() method common
228 to str, bytes and bytearray could be optimized away by the compiler, letting
229 the interpreter segfault instead of raising an error.
230
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000231- Issue #3720: Fix a crash when an iterator modifies its class and removes its

244 amount of loop unrolling.
245
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000246- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
247 collecting the oldest generation) so that allocating lots of objects without

250 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
251
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000252- Issue #4604: Some objects of the I/O library could still be used after

257 flag to work properly. Furthermore, when specifying -u, the text stdout
258 and stderr streams have line-by-line buffering enabled (the default being
259 to buffer arbitrary chunks of data).
260
Raymond Hettinger35631532009-01-09 03:58:09 +0000261- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
262 instead of ints (reducing its size from 4 to 8 times thereby reducing
263 Python's overall memory).
264
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000265- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
266 an existing .py counterpart, override the co_filename attributes of all
267 code objects if the original filename is obsolete (which can happen if the
268 file has been renamed, moved, or if it is accessed through different paths).
269 Patch by Ziga Seilnacht and Jean-Paul Calderone.
270
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000271- Issue #4580: Fix slicing of memoryviews when the item size is greater than
272 one byte. Also fixes the meaning of len() so that it returns the number of
273 items, rather than the size in bytes.
274
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000275- Issue #4075: Use OutputDebugStringW in Py_FatalError.
276
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000277- Issue #4747: When the terminal does not use utf-8, executing a script with
278 non-ascii characters in its name could fail with a "SyntaxError: None" error.

287 where the tp_hash and tp_dict slots are both NULL.
288
Georg Brandlccc47b62008-12-28 11:44:14 +0000289- Issue #4759: None is now allowed as the first argument of
290 bytearray.translate(). It was always allowed for bytes.translate().
291
Skip Montanaro80072cb2008-12-23 03:51:14 +0000292- Added test case to ensure attempts to read from a file opened for writing
293 fail.
294

329 method on file objects with closefd=False. The file descriptor is still
330 kept open but the file object behaves like a closed file. The ``FileIO``
331 object also got a new readonly attribute ``closefd``.
