By using the query results as state.
Blocking queries are efficient when the query matches some results,
because the ModifyIndex of those results, returned as queryMeta.Mindex,
will never change unless the items themselves change.
Blocking queries for non-existent items are not efficient because the
queryMeta.Index can (and often does) change when other entities are
written.
This commit reduces the churn of these queries by using a different
comparison for "has changed". Instead of using the modified index, we
use the existence of the results. If the previous result was "not found"
and the new result is still "not found", we know we can ignore the
modified index and continue to block.
This is done by setting the minQueryIndex to the returned
queryMeta.Index, which prevents the query from returning before a state
change is observed.
This will both save on unnecessary raft operations as well as
unnecessarily incrementing the raft modify index of config entries
subject to no-op updates.
The race detector noticed this initially in `TestAgentConfigWatcherSidecarProxy` but it is not restricted to just tests.
The two main changes here were:
- ensure that before we mutate the internal `agent/local` representation of a Service (for tags or VIPs) we clone those fields
- ensure that there's no function argument joint ownership between the caller of a function and the local state when calling `AddService`, `AddCheck`, and related using `copystructure` for now.
* First phase of refactoring PermissionDeniedError
Add extended type PermissionDeniedByACLError that captures information
about the accessor, particular permission type and the object and name
of the thing being checked.
It may be worth folding the test and error return into a single helper
function, that can happen at a later date.

This commit excludes the health of any service instances from the Node Listing page. This means that if you are viewing the Node listing page you will only see failing nodes if there are any Node Checks failing, Service Instance Health checks are no longer taken into account.
Co-authored-by: Jamie White <jamie@jgwhite.co.uk>
We noticed that the Service Instance listing on both Node and Service views where not taking into account proxy instance health. This fixes that up so that the small health check information in each Service Instance row includes the proxy instances health checks when displaying Service Instance health (afterall if the proxy instance is unhealthy then so is the service instance that it should be proxying)
* Refactor Consul::InstanceChecks with docs
* Add to-hash helper, which will return an object keyed by a prop
* Stop using/relying on ember-data type things, just use a hash lookup
* For the moment add an equivalent "just give me proxies" model prop
* Start stitching things together, this one requires an extra HTTP request
..previously we weren't even requesting proxies instances here
* Finish up the stitching
* Document Consul::ServiceInstance::List while I'm here
* Fix up navigation mocks Name > Service
Fixes#11876
This enforces that multiple xDS mutations are not issued on the same ADS connection at once, so that we can 100% control the order that they are applied. The original code made assumptions about the way multiple in-flight mutations were applied on the Envoy side that was incorrect.
When a wildcard xDS type (LDS/CDS/SRDS) reconnects from a delta xDS stream,
prior to envoy `1.19.0` it would populate the `ResourceNamesSubscribe` field
with the full list of currently subscribed items, instead of simply omitting it
to infer that it wanted everything (which is what wildcard mode means).
This upstream issue was filed in envoyproxy/envoy#16063 and fixed in
envoyproxy/envoy#16153 which went out in Envoy `1.19.0` and is fixed in later
versions (later refactored in envoyproxy/envoy#16855).
This PR conditionally forces LDS/CDS to be wildcard-only even when the
connected Envoy requests a non-wildcard subscription, but only does so on
versions prior to `1.19.0`, as we should not need to do this on later versions.
This fixes the failure case as described here: #11833 (comment)

- Adding a 'Partition' and 'RetryJoin' command allows test cases where
one would like to spin up a Consul Agent in a non-default partition to
test use-cases that are common when enabling Admin Partition on
Kubernetes.
The fix here is two fold:
- We shouldn't be providing the DataSource (which loads the data) with an id when we are creating from within a folder (in the buggy code we are providing the parentKey of the new KV you are creating)
- Being able to provide an empty id to the DataSource/KV repository and that repository responding with a newly created object is more towards the "new way of doing forms", therefore the corresponding code to return a newly created ember-data object. As we changed the actual bug in point 1 here, we need to make sure the repository responds with an empty object when the request id is empty.

We recently changed the intentions form to take a full model of a dc rather than just the string identifier (so {Name: 'dc', Primary: true} vs just 'dc' in order to know whether the DC is the primary or not.
Unfortunately, we only did this on the global intentions page not the per service intentions page. This makes it impossible to save an intention from the per service intention page (whilst you can still save intentions from the global intention page as normal).
The fix here pretty much copy/pastes the approach taken in the global intention edit template over to the per service intention edit template.
Tests have been added for creation in the per service intention section, which again are pretty much just copied from the global one, unfortunately this didn't exist previously which would have helped prevent this.
Update the `/agent/check/deregister/` API endpoint to return a 404
HTTP response code when an attempt is made to de-register a check ID
that does not exist on the agent.
This brings the behavior of /agent/check/deregister/ in line with the
behavior of /agent/service/deregister/ which was changed in #10632 to
similarly return a 404 when de-registering non-existent services.
Fixes#5821
