In short, it means to use Go:sync#WaitGroup.Go. Given code like the following:
if pm.fileBackupDays > 0 {
pm.waitGroup.Add(1)
go func() {
defer pm.waitGroup.Done()
pm.FileCleaner.periodicFileCleanup(pm.context.Done())
}()
}
Change it as follows:
if pm.fileBackupDays > 0 {
pm.waitGroup.Go(func() {
pm.FileCleaner.periodicFileCleanup(pm.context.Done())
})
}
