I am using the CI 3.0.4 version
Problem:
Do not understand the role of _in_progress variables, prevent the cycle of death?
1. Under what circumstances does the cycle of death occur?
2, why is not the first line of the _run_hooks function set it?
3, Is_call (data) The situation is not set _in_progress variable it?
I am puzzled by the effect and usage of this variable, please explain it, thank you.
