---------------------------------

             Summary: To support an HA TO, regex_revalidate.config should not be written to the file system
                 Key: TC-68
                 URL: https://issues.apache.org/jira/browse/TC-68
             Project: Traffic Control
          Issue Type: Improvement
          Components: Traffic Ops
            Reporter: Jeremy Mitchell
             Fix For: 2.0.0


Currently, when an "invalidate content" request is created via one of these 2 routes:

- POST /api/$version/user/current/jobs (thru the API)
- POST /job/external/new (thru the UI)

regex_revalidate.config is written to the file system at the location dictated by the 'snapshot_dir' parameter:

https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/db/seeds.sql#L32

In order to support a highly-available/redundant TO, we need to remove all dependencies on files written to the file system. 

My suggestion is that we remove all calls to snapshot_regex_revalidate() which will stop regex_revalidate.config from being written to the file system.

https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/lib/MojoPlugins/Job.pm#L35

After this is done. regex_revalidate.config can be retrieved like all other ATS config files:

/genfiles/view/:host_name/regex_revalidate.config
