|
|
# To add a new trace event:
|
|
|
|
|
#
|
|
|
|
|
# 1. Choose a name for the trace event. Declare its arguments and format
|
|
|
|
|
# string.
|
|
|
|
|
#
|
|
|
|
|
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
|
|
|
|
|
# trace_multiwrite_cb(). The source file must #include "trace.h".
|

monitor: Simplify event throttling
The event throttling state machine is hard to understand. I'm not
sure it's entirely correct. Rewrite it in a more straightforward
manner:
State 1: No event sent recently (less than evconf->rate ns ago)
Invariant: evstate->timer is not pending, evstate->qdict is null
On event: send event, arm timer, goto state 2
State 2: Event sent recently, no additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is null
On event: store it in evstate->qdict, goto state 3
On timer: goto state 1
State 3: Event sent recently, additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is non-null
On event: store it in evstate->qdict, goto state 3
On timer: send evstate->qdict, clear evstate->qdict,
arm timer, goto state 2
