The idleTTL was being written and read concurrently. Instead move the idleTTL to a struct
field so that when one test patches the TTL it does not impact others.
The background goroutines for the store can outlive a test because context cancellation
is async.
Setting this field to a value is equivalent to using the 'near' query paramter.
The intent is to sort the results by proximity to the node requesting
them. However with connect we send the results to envoy, which doesn't
care about the order, so setting this field is increasing the work
performed for no gain.
It is necessary to unset this field now because we would like connect
to use streaming, but streaming does not support sorting by proximity.
Remove View.Result error return value, it was always nil, and seems like it will likely always remain nill
since it is simply reading a stored value.
Also replace some cache types with local types.
And only start expiration time when the last request ends. This makes tracking expiry simpler, and
ensures that no entry can be expired while there are active requests.
Previously canRetry was attempting to retrieve this error from args, however there was never
any callers that would pass an error to args.
With the change to raftApply to move this error to the error return value, it is now possible
to receive this error from the err argument.
This commit updates canRetry to check for ErrChunkingResubmit in err.
Previously we were inconsistently checking the response for errors. This
PR moves the response-is-error check into raftApply, so that all callers
can look at only the error response, instead of having to know that
errors could come from two places.
This should expose a few more errors that were previously hidden because
in some calls to raftApply we were ignoring the response return value.
Also handle errors more consistently. In some cases we would log the
error before returning it. This can be very confusing because it can
result in the same error being logged multiple times. Instead return
a wrapped error.
Previously only a single auth method would be saved to the snapshot. This commit fixes the typo
and adds to the test, to show that all auth methods are now saved.
This way we avoid serializing these when empty. Otherwise users of the
latest version of the api submodule cannot interact with older versions
of Consul, because a new api client would send keys that the older Consul
doesn't recognize yet.
