(Reported by Kjartan Marass). (Reported by Kjartan Marass).
- Fix bugs/performance issues:
- total should probably be cached so that compute_total() doesn't
take 80% of the time to generate a profile.
- decorate_node should be done lazily
- Find out why we sometimes get completely ridicoulous stacktraces,
where main seems to be called from within Xlib etc. This happens
even after restarting everything.
- It looks like the stackstash-reorg code confuses "main" from
unrelated processes. - currently it looks like if multiple
"main"s are present, only one gets listed in the object list.
- Numbers in caller view are completely screwed up.
- It looks like it sometimes gets confused with similar but different
processess: Something like:
process a spends 80% in foo() called from bar()
process b spends 1% in foo() called from baz()
we get reports of baz() using > 80% of the time.
Or something.
- make the things we put in a stackstash real
objects so that
- we can save them
- they will know how to delete the presentation
names and themselves (through a virtual function)
- they can contain markup etc.
- a more pragmatic approach might be to just walk the tree and
save it.
- make stasckstash ref counted
- plug all the leaks
- don't leak the presentation strings/objects
- loading and saving probably leak right now
- think about loading and saving. Goals
- Can load 1.0 profiles
- Don't export too much of stackstashes to the rest of the
app
- Reorganise stackstash and profile
