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.
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
* ui: Add login button to per service intentions for zero results
* Add login button and consistent header for when you have zero nodes
* `services` doesn't exists use `items` consequently:
Previous to this fix we would not show a more tailored message for when
you empty result set was due to a user search rather than an empty
result set straight from the backend
* Fix `error` > `@error` in ErrorState plus code formatting and more docs
* Changelog
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).
* Update disco fixtures now we have partitions
* Add virtual-admin-6 fixture with partition 'redirects' and failovers
* Properly cope with extra partition segment for splitters and resolvers
* Make 'redirects' and failovers look/act consistently
* Fixup some unit tests
Fixes a bug whereby servers present in multiple network areas would be
properly segmented in the Router, but not in the gRPC mirror. This would
lead servers in the current datacenter leaving from a network area
(possibly during the network area's removal) from deleting their own
records that still exist in the standard WAN area.
The gRPC client stack uses the gRPC server tracker to execute all RPCs,
even those targeting members of the current datacenter (which is unlike
the net/rpc stack which has a bypass mechanism).
This would manifest as a gRPC method call never opening a socket because
it would block forever waiting for the current datacenter's pool of
servers to be non-empty.
