Describe a real-world scenario where you would need to use file locking in Go.

  • Ensuring exclusive access to a configuration file used by multiple instances of a server.
  • Preventing simultaneous writes to a shared log file by multiple processes.
  • Synchronizing access to a database by multiple Go routines.
  • Coordinating access to a read-only resource by parallel Go routines.
In a real-world scenario, file locking in Go is crucial when multiple processes or threads need to write to a shared log file simultaneously. Without file locking, concurrent writes can result in data corruption and unpredictable behavior. By using file locking, you can ensure that only one process has write access to the file at a time, preventing data corruption and maintaining the integrity of the log. This is a common use case for file locking in Go applications.
