- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.
- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.
- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.
- Add a new serf feature flag indicating support for
intentions-as-config-entries.
- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.
- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.
- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.
- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.
This call appears to only be necessary because reset() was called from
NewMaterializer.
This commit has the constructor set a default value for updateCh, and
removes both the call to reset() from New(), and the call to
notifyUpdateLocked() from reset().
This should ensure that we do not notify the Fetch() call before we have new
values to report.
Refactor of Materializer.Run
Use handlers to manage state in Materializer
Rename Materializer receiver
rename m.l to m.lock, and flip some conditionals to remove the negative.
Improve godoc, rename Deps, move resetErr, and pass err into notifyUpdate
Update for NewSnapshotToFollow events
Refactor to move context cancel out of Materializer
Replace InitFilter with Reset.
Removes the need to store a fatalErr and the cache-type, and removes the need to recreate the filter
each time.
Pass dependencies into MaterializedView.
Remove context from MaterializedView.
Rename state to view.
Rename MaterialziedView to Materialzier.
Rename to NewMaterializer
Pass in retry.Waiter
This adds a new very tiny memdb table and corresponding raft operation
for updating a very small effective map[string]string collection of
"system metadata". This can persistently record a fact about the Consul
state machine itself.
The first use of this feature will come in a later PR.
