NAME

Ubic::Daemon::PidState - internal object representing process info stored on disk

VERSION

version 1.58

This is considered to be a non-public class. Its interface is subject to change without notice.

new(): Constructor. Does nothing by itself, doesn't read pidfile and doesn't try to create pid dir.
is_empty(): Check if pid dir doesn't exist yet.
init(): Create pid dir. After this method is called, "is_empty()" will start to return false value.
read(): Read daemon info from pidfile.
Returns undef if pidfile not found. Throws exceptions when content is invalid.
lock() =item lock($timeout): Acquire piddir lock. Lock will be nonblocking unless 'timeout' parameter is set.
remove(): 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?).
write({ pid = $pid, guid => $guid })>: Write guardian pid and guid into the pidfile.
