| 39 Class extending the standard Python profiler with additional methods. | |
| 40 </p> | |
| 41 <p> | |
| 42 This class extends the standard Python profiler by the functionality to | |
| 43 save the collected timing data in a timing cache, to restore these data | |
| 44 on subsequent calls, to store a profile dump to a standard filename and | |
| 45 to erase these caches. | |

| 152 <p> | |
| 153 Public method used to fixup the filename for a given frame. | |
| 154 </p> | |
| 155 <p> | |
| 156 The logic employed here is that if a module was loaded | |
| 157 from a .pyc file, then the correct .py to operate with | |
| 158 should be in the same path as the .pyc. The reason this | |
| 159 logic is needed is that when a .pyc file is generated, the | |
| 160 filename embedded and thus what is readable in the code object | |
| 161 of the frame object is the fully qualified filepath when the | |
| 162 pyc is generated. If files are moved from machine to machine | |
| 163 this can break debugging as the .pyc will refer to the .py | |
| 164 on the original machine. Another case might be sharing | |
| 165 code over a network... This logic deals with that. | |
