Here we are reducing the xhprof runs data by removing the
__Mustache==>__Mustache calls and all the orphaned data.
To save N iterations what we are doing is:
0. The information is "topologically" sorted, so we ensure that
all the parents in the data are processed before the children.
(this will help a lot when cleaning orphaned data, see below).
1. First pass, all the candidate (by regexp) calls are removed
from the run data.
2. Second pass, all the orphaned information (calls that have
ended losing his parent) are also removed, so data is consistent.
Note that, normally we would need N passes to remove all the
orphaned data (because each pass creates new orphan candidates),
but, as far as we have ensured that the information is topologically
sorted (see point 0 above), all this can be done in one unique pass.
TODO:
- Add unit tests.
- Enable some system to be able to decide which utilities we
want to get the data reduced and which ones will continue
using the complete data. Right now the reduction is being
applied to all the utilities (both table and graph views).
- Document the change and, if implemented, the way to select
between complete/reduced data.
- Consider adding some caching to speed-up the reduction process
(some TODOs have been left in the code pointing to the critical
points).
