76-77: Remove unnecessary continue statementThe
continuestatement here is unnecessary as the loop will naturally continue to the next iteration after executing thecaseblock.Consider removing the
continuestatement:case <-ticker.C: v.metrics.reportVersion(v.version) - continue
Line range hint
65-83: Consider adding error handling mechanismThe
Startmethod currently always returnsnil, which doesn't provide any feedback about potential issues during startup. Consider adding an error channel to communicate any errors that might occur in the goroutine back to the caller.Here's a suggested implementation:
func (v *ReportingService) Start(ctx context.Context) error { ticker := time.NewTicker(v.reportingInterval) v.metrics.reportVersion(v.version) errCh := make(chan error, 1) go func() { defer ticker.Stop() defer close(errCh) for { select { case <-ticker.C: if err := v.metrics.reportVersion(v.version); err != nil { errCh <- err return } case <-ctx.Done(): return } } }() return nil }This implementation allows for error propagation from the
reportVersionmethod if needed. You might want to adjust thereportVersionmethod to return an error if it doesn't already.

🛠️ Refactor suggestion
Ensure proper ticker cleanup in case of panic
Moving defer ticker.Stop() inside the goroutine ensures that the ticker continues running until the context is done. However, if the goroutine panics, the ticker might not be stopped properly. Consider adding a panic recovery mechanism to ensure the ticker is always stopped.
Here's a suggested implementation:
go func() {
defer func() {
ticker.Stop()
if r := recover(); r != nil {
v.logger.Error("Panic in version reporting goroutine", "recover", r)
}
}()
for {
select {
case <-ticker.C:
v.metrics.reportVersion(v.version)
case <-ctx.Done():
return
}
}
}()

this is the fix. Ticker should be stopped in the goroutine. If not ticker will be stopped as soon as Start terminates and reportVersion will never be called.
Duly stopping the ticker within the right goroutine
