This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.
Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
Previous getFromView would call view.Result when the result may not have been returned
(because the index is updated past the minIndex. This would allocate a slice and sort it
for no reason, because the values would never be returned.
Fix this by re-ordering the operations in getFromView.
The test changes in this commit were an attempt to cover the case where
an update is received but the index does not exceed the minIndex.
Also rename it to readEntry now that it doesn't return the entire entry. Based on feedback
in PR review, the full entry is not used by the caller, and accessing the fields wouldn't be
safe outside the lock, so it is safer to return only the Materializer
grpclog.SetLoggerV2 is meant to be called only once before any gRPC requests are received, but
each test that uses TestAgent will call NewBaseDeps again. Use a sync.Once to prevent the grpc
logging from being re-initialized by each test.
This will mean that a test can't use a fake logger to capture logs from the gRPC server.
These tests can flake when we get a notification for an earlier event.
Retry the read from update channel a few times to make sure we get the
event we expect.
Split the TestStreamingClient into the two logical components the real
client uses. This allows us to test multiple clients properly.
Previously writing of ctx from multiple Subscribe calls was showing a
data race.
Once this was fixed a test started to fail because the request had to be
made with a greater index, so that the store.Get call did not return
immediately.
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.
