Otherwise when the query times out we might incorrectly send a value for
the reply, when we should send an empty reply.
Also document errNotFound and how to handle the result in that case.
* Delete collapsible notices component and related helper
* Add relative t action/helper to our Route component
* Replace single use CollapsibleNotices with multi-use Disclosure
The interface is documented as 'Sign will only return the leaf', and the other providers
only return the leaf. It seems like this was added during the initial implementation, so
is likely just something we missed. It doesn't break anything , but it does cause confusing cert chains
in the API response which could break something in the future.
* Parse datacenter from request
- Parse the value of the datacenter from the create/delete requests for AuthMethods and BindingRules so that they can be created in and deleted from the datacenters specified in the request.
* Separate Annotations and Labels and add service-ignore label
* changes to structure and call out for pod
* add description and TOC
* Update annotations-and-labels.mdx

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 test shows how blocking queries are not efficient when the query
returns no results. The test fails with 100+ calls instead of the
expected 2.
This test is still a bit flaky because it depends on the timing of the
writes. It can sometimes return 3 calls.
A future commit should fix this and make blocking queries even more
optimal for not-found results.
Follow the Go convention of accepting a small interface that documents
the methods used by the function.
Clarify the rules for implementing a query function passed to
blockingQuery.
We've noticed that a trace that is captured over the full duration is
too large to open on most machines. A trace.out captured over just the
interval period (30s by default) should be a more than enough time to
capture trace data.
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.
