Keyway: A simple lock library

• zokier 12y ago
  Maybe I'm missing something, but shouldn't locks generally have some protections against race conditions? E.g. starting from line 15: acquire_lock_for() { if not_locked $1; then lock_log "Creating $1 lock." touch "$LOCK_DIR/$1".lock check_execution "acquire lock" fi } what if another process creates lock file between the `if not_locked` and `touch` lines?

    Great point. I'll update the library and my blog post with a fix for this. Thanks!
