Anton Kaliaev 431618cef6 lite2: remove auto update (#4535 ) We first introduced auto-update as a separate struct AutoClient, which was wrapping Client and calling Update periodically. // AutoClient can auto update itself by fetching headers every N seconds. type AutoClient struct { base Client updatePeriod time.Duration quit chan struct{} trustedHeaders chan types.SignedHeader errs chan error } // NewAutoClient creates a new client and starts a polling goroutine. func NewAutoClient(base Client, updatePeriod time.Duration) AutoClient { c := &AutoClient{ base: base, updatePeriod: updatePeriod, quit: make(chan struct{}), trustedHeaders: make(chan types.SignedHeader), errs: make(chan error), } go c.autoUpdate() return c } // TrustedHeaders returns a channel onto which new trusted headers are posted. func (c AutoClient) TrustedHeaders() <-chan types.SignedHeader { return c.trustedHeaders } // Err returns a channel onto which errors are posted. func (c AutoClient) Errs() <-chan error { return c.errs } // Stop stops the client. func (c AutoClient) Stop() { close(c.quit) } func (c AutoClient) autoUpdate() { ticker := time.NewTicker(c.updatePeriod) defer ticker.Stop() for { select { case <-ticker.C: lastTrustedHeight, err := c.base.LastTrustedHeight() if err != nil { c.errs <- err continue } if lastTrustedHeight == -1 { // no headers yet => wait continue } newTrustedHeader, err := c.base.Update(time.Now()) if err != nil { c.errs <- err continue } if newTrustedHeader != nil { c.trustedHeaders <- newTrustedHeader } case <-c.quit: return } } } Later we merged it into the Client itself with the assumption that most clients will want it. But now I am not sure. Neither IBC nor cosmos/relayer are using it. It increases complexity (Start/Stop methods). That said, I think it makes sense to remove it until we see a need for it (until we better understand usage behavior). We can always introduce it later 😅. Maybe in the form of AutoClient.		4 years ago
