Thank you for your work on this!
Regarding the implementation, I would actually like to see if we can avoid the additional while block. As you already said you'd be fine with amending, I would just do that.
But, more importantly:
/etc/hosts
in particular should not be used.Hi @delthas, are you still interested in this patch? If yes, I would be interested in your opinion about my two questions:
Shouldn't we make the fallback optional? I fear there might be cases where
/etc/hosts
in particular should not be used.
- Or should we even go one step further and support a list of resolvers to try?
This enables a best-effort, two-step resolution when a resolver is configured:
The patch is somewhat dumb, it just wraps the resolve logic in a loop that can iterate twice. The goal was to minimize the size of
git diff -w
.This causes the module to log Lookup & Results & Error twice in case we do the fallback attempt, which could be a nice side-effect (we can investigate a DNS error in varnishlog but see that it still succeeded). I don't have a strong opinion about this one.
Feel free to amend and merge if you'd like. Otherwise I can make changes. :smile:
