Hi
Version 1
task :check_lb_worker_exists, :roles => :apacluster, :on_error
=> :abort do
if exists?(:modjk_loadbalancerworker) then
begin
run "if wget #{wgetparams} 'http://$CAPISTRANO:HOST$/jkserver-
status?cmd=edit&from=list&w=#{modjk_loadbalancerworker}' | grep
'ERROR'; then false;else true;fi 2>&2>/dev/null;"
rescue
puts "The specified modjk load balancer worker does not
exists"
end
end
end#task
calling the task:
task :preflightcheck, :on_error => :abort do
unless exists?(:app_path)
abort "The download path variable app_path has not been specified"
end
modjk.check_lb_worker_exists
puts 'Everything is fine'
end
This version works fine except that everything is always fine
"regardless whether the check_lb_worker_exists failed or not
version 2
~~~~~~~
task :check_lb_worker_exists, :roles => :apacluster, :on_error
=> :abort do
if exists?(:modjk_loadbalancerworker) then
run "if wget #{wgetparams} 'http://$CAPISTRANO:HOST$/jkserver-
status?cmd=edit&from=list&w=#{modjk_loadbalancerworker}' | grep
'ERROR'; then false;else true;fi ;"
end
end#task
task :preflightcheck, :on_error => :abort do
unless exists?(:app_path)
abort "The download path variable app_path has not been specified"
end
unless not modjk.check_lb_worker_exists
abort 'horribly broken'
end
puts 'all looks fine!'
end
In version two if the check_lb_worker task fails that failure does not
get handled by the unless abort block in the main preflight check.
Basically I am trying to do the following:
task preflight
unless run(some command) fail
unless run_task_check1, fail with nice message
unless run_task_check2, fail with nice message
if nothing failed then put "everything looks ok"
end
I am struggling to get the final "everything looks ok" message to
display only if everything really is ok because at the moment it
displays regardless. I hope this is all making some kind of sense...
otherwise I will have to try again.
Regards
