Leif Hedstrom commented on TS-3364:
-----------------------------------

Ya, pushing to prod, and let it fail, seems like a bad idea. Thinking about it, 
rather than traffic_line/_ctrl, it'll probably be a lot easier to add this 
verification process to traffic_server. E.g.

{code}
traffic_server -Cverify
{code}

And let it load all configs, and then shutdown and exit with either 0 for 
success, or a status code indicating what went wrong.

> Add configuration to control traffic_server's reaction to fatal errors  
> during (re)loading the config files.

>
> Currently, traffic_server fails to initialize when it encounters fatal errors 
> in loading the config files during start up. During dynamic reloading of 
> config files (e.g. via traffic_line), traffic_server rejects new config and 
> falls back to existing/old config (however, if there was a traffic_server 
> crash/restart subsequently, that can again result into failing to initialize).
> This jira proposes to make the behavior of traffic_server when it encounters 
> such fatal errors configurable via a new setting 
> {{proxy.config.ignore_fatal_errors}} with the below options:
> {code}
> 0 : All errors are fatal, do not load/reload
> 1 : Ignore a bad config line, continue with the rest
> 2 : Ignore a bad config line, stop parsing the file further
> ..
> {code}
