I'm attempting to implement delegation with func 0.28. So far I've:
. Added Delegate = True to /etc/func/overlord.conf on the master overlord server
. Run func-build-map
Currently all hosts are directly pingable by the overlord. When I run something
like func "*" ping I get this:
Traceback (most recent call last):
File "/usr/bin/func", line 28, in ?
ret = cli.parse(argv)
File "/usr/lib/python2.4/site-packages/func/overlord/command.py", line 252,
in parse
return self.subCommands[command].parse(args[1:])
File "/usr/lib/python2.4/site-packages/func/overlord/command.py", line 233,
in parse
ret = self.do(args)
File "/usr/lib/python2.4/site-packages/func/overlord/cmd_modules/ping.py",
line 66, in do
results = overlord_obj.run("test", "ping", [])
File "/usr/lib/python2.4/site-packages/func/overlord/client.py", line 791, in
run
directhash.update(self.run_direct(module,method,args,nforks))
TypeError: iteration over non-sequence
I added some pretty printing to the args:
module:
'test'
method:
'ping'
args:
[]
nforks:
1
If I do something more complicated, here's what I get:
func "*" call command run "cat /etc/hosts"
module:
'jobs'
method:
'job_status'
args:
('1308912977.796803-minion',)
nforks:
1

TypeError: cannot convert dictionary update sequence element #0 to a sequence
If I turn off delegation, all works well.
Anyone have any ideas about what's going on and how I can further debug the
issue?
