Allow disabling the HTTP API again. (#4655) 
If you provide an invalid HTTP configuration consul will still start again instead of failing. But if you do so the build-in proxy won't be able to start which you might need for connect.

Ensure that errors setting up the DNS servers get propagated back to the shell (#4598) 
Fixes: #4578 

Prior to this fix if there was an error binding to ports for the DNS servers the error would be swallowed by the gated log writer and never output. This fix propagates the DNS server errors back to the shell with a multierror.

Fix #4515: Segfault when serf_wan port was -1 but reconnect_time_wan was set (#4531) 
Fixes #4515 

This just slightly refactors the logic to only attempt to set the serf wan reconnect timeout when the rest of the serf wan settings are configured - thus avoiding a segfault.

Matt Keeler 3fe5f566f2 Persist proxies from config files 
Also change how loadProxies works. Now it will load all persisted proxies into a map, then when loading config file proxies will look up the previous proxy token in that map.

Setup managed proxy environment with API client env vars
 2018-07-12 09:13:54 -04:00
Paul Banks bb9a5c703b
Default managed proxy TCP check address sanely when proxy is bound to 0.0.0.0. 
This also provides a mechanism to configure custom address or disable the check entirely from managed proxy config.

Proxy now doesn’t need to know anything about the api as we pass env vars to it instead of the api config.

Paul Banks e57aa52ca6 Warn about killing proxies in dev mode 2018-06-25 12:24:16 -07:00
Paul Banks d1c67d90bc Fixs a few issues that stopped this working in real life but not caught by tests: 
- Dev mode assumed no persistence of services although proxy state is persisted which caused proxies to be killed on startup as their services were no longer registered. Fixed.
 - Didn't snapshot the ProxyID which meant that proxies were adopted OK from snapshot but failed to restart if they died since there was no proxyID in the ENV on restart
 - Dev mode with no persistence just kills all proxies on shutdown since it can't recover them later
 - Naming things

Paul Banks 8cf4b3a6eb Sanity check that we are never trying to self-exec a test binary. Add daemonize bypass for TestAgent so that we don't have to jump through ridiculous self-execution hooks for every package that might possibly invoke a managed proxy 2018-06-25 12:24:09 -07:00
Paul Banks 2b377dc624 Run daemon processes as a detached child. 
This turns out to have a lot more subtelty than we accounted for. The test suite is especially prone to races now we can only poll the child and many extra levels of indirectoin are needed to correctly run daemon process without it becoming a Zombie.

I ran this test suite in a loop with parallel enabled to verify for races (-race doesn't find any as they are logical inter-process ones not actual data races). I made it through ~50 runs before hitting an error due to timing which is much better than before. I want to go back and see if we can do better though. Just getting this up.

agent: leaf endpoint accepts name, not service ID 
This change is important so that requests can made representing a
service that may not be registered with the same local agent.
