- unexport testing shims, and document their purpose
- resolve a TODO by moving validation to NewBuilder and storing the one
field that is used instead of all of Options
- create a slice with the correct size to avoid extra allocations
I saw this test flake locally, and it was easy to reproduce with -count=10.
The failure was: 'TestAgent.dns: rpc error: error=No known Consul servers'.
Waiting for the agent seems to fix it.
This commit fixes a test that I saw flake locally while running tests. The test output from the monitor
started immediately after the line the test was looking for.
To fix the problem a channel is closed when the goroutine starts. Shutdown is not called until this channel
is closed, which seems to greatly reduce the chance of a flake.
TestAgent.Key was only used by 3 tests. Extracting it from the common helper that is used in hundreds of
tests helps keep the shared part small and more focused.
This required a second change (which I was planning on making anyway), which was to change the behaviour of
DataDir. Now in all cases the TestAgent will use the DataDir, and clean it up once the test is complete.
There are a couple reasons for this change:
1. agent.go is way too big. Smaller files makes code eaasier to read
because tools that show usage also include filename which can give
a lot more context to someone trying to understand which functions
call other functions.
2. these two functions call into a large number of functions already in
keyring.go.
This is a small step to allowing Agent to accept its dependencies
instead of creating them in New.
There were two fields in autoconfig.Config that were used exclusively
to load config. These were replaced with a single function, allowing us
to move LoadConfig back to the config package.
Also removed the WithX functions for building a Config. Since these were
simple assignment, it appeared we were not getting much value from them.
Making these functions allows us to cleanup how an agent is initialized. They only make use of a config and a logger, so they do not need to be agent methods.
Also cleanup the testing to use t.Run and require.
Fixes#8466
Since Consul 1.8.0 there was a bug in how ingress gateway protocol
compatibility was enforced. At the point in time that an ingress-gateway
config entry was modified the discovery chain for each upstream was
checked to ensure the ingress gateway protocol matched. Unfortunately
future modifications of other config entries were not validated against
existing ingress-gateway definitions, such as:
1. create tcp ingress-gateway pointing to 'api' (ok)
2. create service-defaults for 'api' setting protocol=http (worked, but not ok)
3. create service-splitter or service-router for 'api' (worked, but caused an agent panic)
If you were to do these in a different order, it would fail without a
crash:
1. create service-defaults for 'api' setting protocol=http (ok)
2. create service-splitter or service-router for 'api' (ok)
3. create tcp ingress-gateway pointing to 'api' (fail with message about
protocol mismatch)
This PR introduces the missing validation. The two new behaviors are:
1. create tcp ingress-gateway pointing to 'api' (ok)
2. (NEW) create service-defaults for 'api' setting protocol=http ("ok" for back compat)
3. (NEW) create service-splitter or service-router for 'api' (fail with
message about protocol mismatch)
In consideration for any existing users that may be inadvertently be
falling into item (2) above, that is now officiall a valid configuration
to be in. For anyone falling into item (3) above while you cannot use
the API to manufacture that scenario anymore, anyone that has old (now
bad) data will still be able to have the agent use them just enough to
generate a new agent/proxycfg error message rather than a panic.
Unfortunately we just don't have enough information to properly fix the
config entries.

NotifyShutdown was only used for testing. Now that t.Cleanup exists, we
can use that instead of attaching cleanup to the Server shutdown.
The Autopilot test which used NotifyShutdown doesn't need this
notification because Shutdown is synchronous. Waiting for the function
to return is equivalent.
AutoConfig will generate local tokens for clients and the ability to use local tokens is gated off of token replication being enabled and being configured with a replication token. Therefore we already have a hard requirement on having token replication enabled, this commit just makes sure to surface that to the operator instead of having to discern what the issue is from RPC errors.
This code started as an optimization to avoid doing an RPC Ping to
itself. But in a single server cluster the rebalancing was led to
believe that there were no healthy servers because foundHealthyServer
was not set. Now this is being set properly.
Fixes#8401 and #8403.
Now that it is no longer used, we can remove this unnecessary field. This is a pre-step in cleanup up RuntimeConfig->Consul.Config, which is a pre-step to adding a gRPCHandler component to Server for streaming.
Removing this field also allows us to remove one of the return values from logging.Setup.
The main bug was fixed in cb050b280c, but the return value of 'result' is still misleading.
Change the return value to nil to make the code more clear.
