The instrumentation of DAG simulation is still possible through the regular instrumentation API based on the Paje format. S4U: - - New function: Engine::run_until(date), to split the simulation. - - New signal: Activity::on_veto, to detect when an activity fails to start. - - New function: Engine::track_vetoed_activities() to interrupt run() - when an activity fails to start, and to keep track of such activities. - Please see the corresponding example for more info. - Introduce on_X_cb() functions for all signals, to attach a new callback to the signal X. The signal variables are now hidden and only these functions should be used.
