There was some note in a presentation you gave quite a while ago that HotShot could profile C extension functions, but I believe that would have required a change to the main python interpreter loop. Does it
It would have required an interpreter change which, I believe, was never made. There may be a patch for this on SourceForge; I don't remember. You can search the patch and bug trackers for "hotshot" to see what's there; I afraid I don't remember the specific changes that were involved. The mechanism discussed at the time would have allowed measuring the time spent in calls to PyCFunction objects (extension functions), but would not have provided per-line information for those functions. The goals was as much to subtract the time spent in C code from the time allocated to the Python function itself more than to actually provide measurement of the C function itself (though some information falls out of that naturally). -Fred -- Fred L.
