Ubic::Daemon::PidState - internal object representing process info stored on disk
version 1.34
Constructor. Does nothing by itself, doesn't read pidfile and doesn't try to create pid dir.
Check if pid dir doesn't exist yet.
Create pid dir. After tihs method is called, is_empty() will start to return false value.
is_empty()
Read daemon info from pidfile.
Returns undef if pidfile not found. Throws exceptions when content is invalid.
Acquire piddir lock. Lock will be nonblocking unless 'timeout' parameter is set.
Remove the pidfile from the piddir. is_empty() will still return false.
This method should be called only after lock is acquired via lock() method (TODO - check before removing?).
lock()
Write guardian pid and guid into the pidfile.
