示例1: Put
// Put implements the Alerts interface.
func (a *Alerts) Put(alerts ...*types.Alert) error {
dbmtx.Lock()
defer dbmtx.Unlock()
tx, err := a.db.Begin()
if err != nil {
return err
}
// The insert invariant requires that there are no two alerts with the same
// fingerprint that have overlapping activity range ([StartsAt:EndsAt]).
// Such alerts are merged into a single one with the union of both intervals
// as its new activity interval.
// The exact merge procedure is defined on the Alert structure. Here, we just
// care about finding intersecting alerts for each new inserts, deleting them
// if existant, and insert the new alert we retrieved by merging.
