I am trying to configure fastrouter through environment variable and  
running into trouble.

1. A blank loop still seems to run… expect that no subscription would  
take place?

[uwsgi]  
…  
fastrouter\_keys=  
fastrouter\_ip=  
fastrouter\_port=

# Subscribe this instance to a fastrouter

for=%(fastrouter\_keys)  
subscribe-to=%(fastrouter\_ip):%(fastrouter\_port):%(\_)  
endfor=

and the log …

subscribing to ::  
send\_subscription()/sendto(): Invalid argument [core/subscription.c line  
665]  
send\_subscription()/sendto(): Invalid argument [core/subscription.c line  
665]  
send\_subscription()/sendto(): Invalid argument [core/subscription.c line  
665]

1. A list of values is treated single?

export FASTROUTER\_KEYS=“a b c”

[uwsgi]  
fastrouter\_keys=$(FASTROUTER\_KEYS)  
fastrouter\_ip=…  
fastrouter\_port=…

# Subscribe this instance to a fastrouter

for=%(fastrouter\_keys)  
subscribe-to=%(fastrouter\_ip):%(fastrouter\_port):%(\_)  
endfor=

And logs on fastrouter

[uwsgi-subscription for pid 5] new pool: a b c (hash key: 3007)  
fastrouter\_1 | [uwsgi-subscription for pid 5] a b c =\> new node:  
172.17.1.37:56481

I was expecting to see three separate subscribes.

Any help appreciated.

This looks unrelated to nginx. You may have better luck asking in  
uWSGI mailing lists instead.
