Description
Server shutdown causes any PHP script hanging on an event stream to receive a SIGTERM signal and exit, bypassing all normal error handlers.
Using the pcntl extension I'm able to keep my script running and reconnect every X seconds. When the signal is ignored I'm able to catch exceptions that are thrown out of the driver.
e.g.
php
pcntl_signal( SIGTERM, SIG_IGN );
while ( true ){
try {
// connect and do cool stream stuff
}
catch( Exception $e ){
sleep(5);
}
}
This is all good, except I don't know what other signals could occur. Is SIGTERM the only likely signal I need to catch?
Also, it feels like forced script termination isn't good driver behaviour when a server connection disappears. Is this intentional, or unavoidable?
