Adds a re-usable lockfile_nonblocking helper to context_managers. Relying on naive `os.mkdir` is not enough especially now that the successful operation of this command is necessary for push notifications to work for many servers. We can't use `lockfile` context manager from `zerver.lib.context_managers`, because we want the custom behavior of failing if the lock can't be acquired, instead of waiting. That's because if an instance of this gets stuck, we don't want to start queueing up more processes waiting forever whenever the cronjob runs again and fail->exit is preferrable instead. |
