Also:
* Finished threading replaceExistingChecks setting (from GH-4905)
through service manager.
* Respected the original configSource value that was used to register a
service or a check when restoring persisted data.
* Run several existing tests with and without central config enabled
(not exhaustive yet).
* Switch to ioutil.ReadFile for all types of agent persistence.
The fields in the certs are meant to hold the original binary
representation of this data, not some ascii-encoded version.
The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).
This only affects vault versions >=1.1.1 because the prior code
accidentally relied upon a bug that was fixed in
https://github.com/hashicorp/vault/pull/6505
The existing tests should have caught this, but they were using a
vendored copy of vault version 0.10.3. This fixes the tests by running
an actual copy of vault instead of an in-process copy. This has the
added benefit of changing the dependency on vault to just vault/api.
Also update VaultProvider to use similar SetIntermediate validation code
as the ConsulProvider implementation.
When running 'make tools' the go command indirectly edits both the
go.mod and go.sum files in ways that can cause the later build of consul
itself to build with slightly different dependencies than it normally
would.
Also needed to update some funcs that were taking a *testing.T to use a testing.TB. This prevents passing a nil pointer as a non-nil interface value
and thus making it impossible to detect nil before using the interfaces functions.
* Add build system support for protobuf generation
This is done generically so that we don’t have to keep updating the makefile to add another proto generation.
Note: anything not in the vendor directory and with a .proto extension will be run through protoc if the corresponding namespace.pb.go file is not up to date.
If you want to rebuild just a single proto file you can do so with: make proto-rebuild PROTOFILES=<list of proto files to rebuild>
Providing the PROTOFILES var will override the default behavior of finding all the .proto files.
* Start adding types to the agent/proto package
These will be needed for some other work and are by no means comprehensive.
* Add ability to resolve/fixup the agentpb.ACLLinks structure in the state store.
* Use protobuf marshalling of raft requests instead of msgpack for protoc generated types.
This does not change any encoding of existing types.
* Removed structs package automatically encoding with protobuf marshalling
Instead the caller of raftApply that wants to opt-in to protobuf encoding will have to call `raftApplyProtobuf`
* Run update-vendor to fixup modules.txt
Nothing changed as far as dependencies go but the ordering of modules in that file depends on the time they are first seen and its not alphabetical.
* Rename some things and implement the structs.RPCInfo interface bits
agentpb.QueryOptions and agentpb.WriteRequest implement 3 of the 4 RPCInfo funcs and the new TargetDatacenter message type implements the fourth.
* Use the right encoding function.
* Renamed agent/proto package to agent/agentpb to prevent package name conflicts
* Update modules.txt to fix ordering
* Change blockingQuery to take in interfaces for the query options and meta
* Add %T to error output.
* Add/Update some comments
- fix instructions for CoreDNS (it updated)
- fix instructions for new component names
- recommend installing with the name 'consul'
- add disclaimer that catalog sync is not always required
- clean up example values.yaml files
This should cut down on test flakiness.
Problems handled:
- If you had enough parallel test cases running, the former circular
approach to handling the port block could hand out the same port to
multiple cases before they each had a chance to bind them, leading to
one of the two tests to fail.
- The freeport library would allocate out of the ephemeral port range.
This has been corrected for Linux (which should cover CI).
- The library now waits until a formerly-in-use port is verified to be
free before putting it back into circulation.
In normal operations there is a read/write race related to request
QueryOptions fields. An example race:

This patch does a lightweight copy of the request struct so that the
embedded QueryOptions fields that are mutated during Fetch() are scoped
to just that one RPC.
