Description
Using function call stacks for comparing error traces is very inaccurate. I suppose to use model function call trees, i.e. trees (but with the determined order of children) of function names where all leaves are model functions that are functions with notes (all such the functions should be necessary in these trees) while intermediate nodes constitute corresponding function call stacks (they can include model functions as well).
For instance, if the error trace looks like:
func1():
...
func2():
...
model_func1():
...
model_func2():
...
func3():
model_func3():
...
then its function call tree will be the following:
func1
func2 model_func2 func3
model_func1 model_func3
(note that the order of children does matter).
Comparing error traces by model function call trees looks to be trivial for explanation.
I suppose to use new functions for extraction and comparison criterion by default.

There were already too many urgent issues for Vladimir.

Done in branch "feature_7168". Set these function as default. You need just "population" to add them to existing database.
- Status changed from Resolved to Open
I don't know why, but simple call stack comparison doesn't work in this branch any more - error traces aren't associated with marks that used this criterion even if these marks are created on the basis of these error traces.

I can't reproduce this bug. Maybe you forgot to change error trace convertion function? This branch just add new functions and set them as default. These changes doesn't affect simple call stack functions. Population doesn't delete any associations and doesn't create new.
I offer to disable changing comparison function for mark because it depends on convertion function, which you can't change for existing marks.
Yes, you are right twice. But let's think about functions bind in another issue (I agree that some ones do strictly bind, but the relation is many-to-many, besides users will be able to specify their own pattern error traces one day).
- Status changed from Open to Closed

I merged the branch to master in 926dc80.
Please, note that you need to populate new functions.
