This commit switches all usage of math/rand to cmn's rand. The only exceptions are within the random file itself, the tools package, and the crypto package. In tools you don't want it to lock between the go-routines. The crypto package doesn't use it so the crypto package have no other dependencies within tendermint/tendermint for easier portability. Crypto/rand usage is unadjusted. Closes #1343 |

Overview
Pub-Sub in go with event caching
Index
Package files
type EventCache
type EventCache struct {
// contains filtered or unexported fields
}
An EventCache buffers events for a Fireable All events are cached. Filtering happens on Flush
func NewEventCache
func NewEventCache(evsw Fireable) *EventCache
Create a new EventCache with an EventSwitch as backend
func (*EventCache) FireEvent
func (evc *EventCache) FireEvent(event string, data EventData)
Cache an event to be fired upon finality.
func (*EventCache) Flush
func (evc *EventCache) Flush()
Fire events by running evsw.FireEvent on all cached events. Blocks. Clears cached events
type EventCallback
type EventCallback func(data EventData)
type EventData
type EventData interface {
}
Generic event data can be typed and registered with tendermint/go-amino via concrete implementation of this interface
type EventSwitch
type EventSwitch interface {
cmn.Service
Fireable
AddListenerForEvent(listenerID, event string, cb EventCallback)
RemoveListenerForEvent(event string, listenerID string)
RemoveListener(listenerID string)
}
func NewEventSwitch
func NewEventSwitch() EventSwitch
type Eventable
type Eventable interface {
SetEventSwitch(evsw EventSwitch)
}
reactors and other modules should export this interface to become eventable
type Fireable
type Fireable interface {
FireEvent(event string, data EventData)
}
an event switch or cache implements fireable
