I need trace python projects, with low over head and a little flexibility.
There are some pure python based trace tools, but most of them make
codes slower. I also tried systemtap, but it still become much slower
in complicated python codes. I'm now finding a better tool or some
inspirations.
Flexibility for me means that operators could write some scripts to
choose what to trace. Someone traces function A, and someone traces B
for other purposes. Using the android case as example, I think I could
control the format of input data to manage trace objects. However I'm
not confident with this idea.
