| 45 Class extending the standard Python profiler with additional methods. | |
| 46 </p><p> | |
| 47 This class extends the standard Python profiler by the functionality to | |
| 48 save the collected timing data in a timing cache, to restore these data | |
| 49 on subsequent calls, to store a profile dump to a standard filename and | |
| 50 to erase these caches. | |

| 131 Public method used to fixup the filename for a given frame. | |
| 132 </p><p> | |
| 133 The logic employed here is that if a module was loaded | |
| 134 from a .pyc file, then the correct .py to operate with | |
| 135 should be in the same path as the .pyc. The reason this | |
| 136 logic is needed is that when a .pyc file is generated, the | |
| 137 filename embedded and thus what is readable in the code object | |
| 138 of the frame object is the fully qualified filepath when the | |
| 139 pyc is generated. If files are moved from machine to machine | |
| 140 this can break debugging as the .pyc will refer to the .py | |
| 141 on the original machine. Another case might be sharing | |
| 142 code over a network... This logic deals with that. | |
