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)

The gist here is that now we use a value-type struct proxycfg.UpstreamID
as the map key in ConfigSnapshot maps where we used to use "upstream
id-ish" strings. These are internal only and used just for bidirectional
trips through the agent cache keyspace (like the discovery chain target
struct).
For the few places where the upstream id needs to be projected into xDS,
that's what (proxycfg.UpstreamID).EnvoyID() is for. This lets us ALWAYS
inject the partition and namespace into these things without making
stuff like the golden testdata diverge.

ActiveRoot should not be called from the secondary DC, because there
should not be a requirement to run the same Vault instance in a
secondary DC. SignIntermediate is called in a secondary DC, so it should
not call ActiveRoot
We would also like to change the interface of ActiveRoot so that we can
support using an intermediate cert as the primary CA in Consul. In
preparation for making that change I am reducing the number of calls to
ActiveRoot, so that there are fewer code paths to modify when the
interface changes.
This change required a change to the mockCAServerDelegate we use in
tests. It was returning the RootCert for SignIntermediate, but that is
not an accurate fake of production. In production this would also be a
separate cert.
Immediately above this line we are already appending the full list of
intermediates. The `provider.ActiveIntermediate` MUST be in this list of
intermediates because it must be available to all the other non-leader
Servers. If it was not in this list of intermediates then any proxy
that received data from a non-leader would have the wrong certs.
This is being removed now because we are planning on changing the
`Provider.ActiveIntermediate` interface, and removing these extra calls ahead of
time helps make that change easier.
Using tracing and cpu profiling I found that the majority of the time in
these test cases is spent generating a private key. We really don't need
separate private keys, so we can generate only one and use it for all
cases.
With this change the test runs much faster.
Fix the name to match the function it is testing
Remove unused code
Fix the signature, instead of returning (error, string) which should be (string, error)
accept a testing.T to emit errors.
Handle the error from encode.
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
* clone the service under lock to avoid a data race
* add change log
* create a struct and copy the pointer to mutate it to avoid a data race
* fix failing test
* revert added space
* add comments, to clarify the data race.
The only function passed to SnapshotRPC today always returns a nil error, so there's no
way to exercise this bug in practice. This change is being made for correctness so that
it doesn't become a problem in the future, if we ever pass a different function to
SnapshotRPC.
Error messages related to service and check operations previously included
the following substrings:
- service %q
- check %q
From this error message, it isn't clear that the expected field is the ID for
the entity, not the name. For example, if the user has a service named test,
the error message would read 'Unknown service "test"'. This is misleading -
a service with that *name* does exist, but not with that *ID*.
The substrings above have been modified to make it clear that ID is needed,
not name:
- service with ID %q
- check with ID %q
Previously we could get into a state where discovery chain entries were
not cleaned up after the associated watch was cancelled. These changes
add handling for that case where stray chain references are encountered.
When a URL path is not found, return a non-empty message with the 404 status
code to help the user understand what went wrong. If the URL path was not
prefixed with '/v1/', suggest that may be the cause of the problem (which is a
common mistake).

This query has been incorrectly querying by accessor ID since New ACLs
were added. However, the legacy token compat allowed this to continue to
work, since it made a fallback query for the anonymousToken ID.
PR #11184 removed this legacy token query, which means that the query by
accessor ID is now the only check for the anonymous token's existence.
This PR updates the GetBySecret call to use the secret ID of the token.
