Benjamin Peterson | 7fe9853 | 2009-04-02 00:33:55 +0000 | [diff] [blame] | 20 | - Issue #5499: The 'c' code for argument parsing functions now only accepts a |
| 21 | byte, and the 'C' code only accepts a unicode character. |
| 22 | |
Brett Cannon | 0759dd6 | 2009-04-01 18:13:07 +0000 | [diff] [blame] | 23 | - Issue #1665206: Remove the last eager import in _warnings.c and make it lazy. |
| 24 | |
Georg Brandl | ab6f2f6 | 2009-03-31 04:16:10 +0000 | [diff] [blame] | 25 | - Fix a segfault when running test_exceptions with coverage, caused by |

| 29 | imp.find_module() were converted to UTF-8 while the path is |
| 30 | converted to the default filesystem encoding, causing nonsense. |
| 31 | |

| 36 | |
Antoine Pitrou | 3a652b1 | 2009-03-23 18:52:06 +0000 | [diff] [blame] | 37 | - Issue #4688: Add a heuristic so that tuples and dicts containing only |
| 38 | untrackable objects are not tracked by the garbage collector. This can |
| 39 | reduce the size of collections and therefore the garbage collection overhead |
| 40 | on long-running programs, depending on their particular use of datatypes. |

| 47 | 2**15 for the internal representation of integers, for performance |
| 48 | reasons. Base 2**30 is enabled by default on 64-bit machines. Add |
| 49 | --enable-big-digits option to configure, which overrides the |
| 50 | default. Add sys.int_info structseq to provide information about |
| 51 | the internal format. |
| 52 | |
Mark Dickinson | 081dfee | 2009-03-18 14:47:41 +0000 | [diff] [blame] | 53 | - Issue #4474: PyUnicode_FromWideChar now converts characters outside |
| 54 | the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4 |

Antoine Pitrou | 652e707 | 2009-03-13 19:25:20 +0000 | [diff] [blame] | 60 | - Issue #5392: when a very low recursion limit was set, the interpreter would |
| 61 | abort with a fatal error after the recursion limit was hit twice. |
| 62 | |
Matthias Klose | 042f133 | 2009-04-04 14:32:42 +0000 | [diff] [blame] | 63 | - Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with |
