CONFIG proxy.config.dns.nameservers should take into effect
-----------------------------------------------------------
Key: TS-437
URL: https://issues.apache.org/jira/browse/TS-437
Project: Traffic Server
Issue Type: Bug
Affects Versions: 2.1.2
Environment: v2.1.2 and trunk
Reporter: Zhao Yongming
CONFIG proxy.config.dns.nameservers is the nameserver specified to TS, but it
does not take into effect without setting of
proxy.config.dns.round_robin_nameservers. please refer file DNS.cc:
DNSProcessor::dns_init
and even if setup proxy.config.dns.round_robin_nameservers, the nameserver
setting from system default /etc/resolv.conf is take into active.
as the SplitDNS have separated file to config, we should make some clear usage
of this proxy.config.dns.nameservers and system default config.
I think proxy.config.dns.nameservers is a setting to let TS use dedicate DNS
server for it, and if all that hosts failed, we then use system default. if
they specify proxy.config.dns.round_robin_nameservers too, then we use rr mode
in all NS servers.
any comments?
