Summary: [Playground] Fix synchronous validators
Key: BEAM-13360
URL: https://issues.apache.org/jira/browse/BEAM-13360
Project: Beam
Issue Type: Bug
Components: beam-playground
Reporter: Ilya Kozyrev
For validators, we start a single goroutine for validateFunc in which we loop
through all validators synchronously.
{code:java}
go validateFunc(successChannel, errorChannel, valResChannel)
// Validate returns the function that applies all validators of executor
func (ex *Executor) Validate() func(chan bool, chan error) {
return func(doneCh chan bool, errCh chan error) {
for _, validator := range ex.validators {
err := validator.Validator(validator.Args...)
if err != nil {
errCh <- err
doneCh <- false
return
}
}
doneCh <- true
}
}
{code}
Instead of that, we should start goroutines for each loop step. And control
results for each validator with separate channels.
