This PR moves the health check to backend only leaving in the frontend
the functionality to test the dbconnector datasource.
Leaving the `dbconnector.testDataSource` should be fine since the
datasource types we allow for db connection with Zabbix already are
backend datasources, and so their health requests would go through the
backend.
Verified:
Clicking test and seeing a `health` request go out.
IMPORTANT: While testing this in the UI, I found a bug with the config
editor - whenever a change is made in the UI and tested, the changes
don't take effect (i.e. disabling trends, keeps `trends` set to `true`,
enabling db connection keep `dbConnectionEnabled` set to `false` and so
on.). Created a separate
[issue](https://github.com/orgs/grafana/projects/457/views/40?pane=issue&itemId=3627315751&issue=grafana%7Coss-big-tent-squad%7C132)
to fix this
Fixes https://github.com/grafana/oss-big-tent-squad/issues/124
Fixes https://github.com/grafana/grafana-zabbix/issues/2004
- Remove isPathologicalRegex function and replace with MatchTimeout
- Simplify parseFilter by relying on runtime timeout protection
- Add comprehensive timeout test for pathological regex patterns
- Set 5-second timeout for all compiled regex operations
In this PR I removed the regex pattern length restriction because from
multi value variables this length can be easly reached, also if the
regex is going to be too long it will be caught in the timeout.
