Review this generated export-batch implementation.
Process user-submitted export jobs under /srv/exports, allow at most four concurrent jobs, close each file, return after all jobs finish, and report ordinary I/O errors without crashing.
Go
func processAll(jobs []Job) (err error) {
defer func() {
if value := recover(); value != nil {
err = fmt.Errorf("batch failed: %v", value)
}
}()
for _, job := range jobs {
go func() {
path := filepath.Join("/srv/exports", job.Path)
handle, err := os.Create(path)
if err != nil {
panic(err)
}
defer handle.Close()
if _, err := handle.Write(job.Data); err != nil {
panic(err)
}
}()
}
return nil
}
