This provides a user with a better experience, knowing that the command
worked appropriately. The output of the write/delete CLI commands are
not going to be used in a bash script, in fact previously a success
provided no ouput, so we do not have to worry about spurious text being
injected into bash pipelines.
The json decoder inside of the HCLv1 hcl.Decode function behaves
unexpectedly when decoding generically into a map[string]interface{} as
is done for 'consul config write' pre-submit decoding.
This results in some subtle (service-router Match and Destinations being
separated) and some not so subtle (service-resolver subsets and failover
panic if multiple subsets are referenced) bugs when subsequently passed
through mapstructure to finish decoding.
Given that HCLv1 is basically frozen and the HCL part of it is fine
instead of trying to figure out what the underlying bug is in the json
decoder for our purposes just sniff the byte slice and selectively use
the stdlib json decoder for JSON and hcl decoder for HCL.
Both 'consul config write' and server bootstrap config entries take a
decoding detour through mapstructure on the way from HCL to an actual
struct. They both may take in snake_case or CamelCase (for consistency)
so need very similar handling.
Unfortunately since they are operating on mirror universes of structs
(api.* vs structs.*) the code cannot be identitical, so try to share the
kind-configuration and duplicate the rest for now.
* Add HTTP endpoints for config entry management
* Finish implementing decoding in the HTTP Config entry apply endpoint
* Add CAS operation to the config entry apply endpoint
Also use this for the bootstrapping and move the config entry decoding function into the structs package.
* First pass at the API client for the config entries
* Fixup some of the ConfigEntry APIs
Return a singular response object instead of a list for the ConfigEntry.Get RPC. This gets plumbed through the HTTP API as well.
Dont return QueryMeta in the JSON response for the config entry listing HTTP API. Instead just return a list of config entries.
* Minor API client fixes
* Attempt at some ConfigEntry api client tests
These don’t currently work due to weak typing in JSON
* Get some of the api client tests passing
* Implement reflectwalk magic to correct JSON encoding a ProxyConfigEntry
Also added a test for the HTTP endpoint that exposes the problem. However, since the test doesn’t actually do the JSON encode/decode its still failing.
* Move MapWalk magic into a binary marshaller instead of JSON.
* Add a MapWalk test
* Get rid of unused func
* Get rid of unused imports
* Fixup some tests now that the decoding from msgpack coerces things into json compat types
* Stub out most of the central config cli
Fully implement the config read command.
* Basic config delete command implementation
* Implement config write command
* Implement config list subcommand
Not entirely sure about the output here. Its basically the read output indented with a line specifying the kind/name of each type which is also duplicated in the indented output.
* Update command usage
* Update some help usage formatting
* Add the connect enable helper cli command
* Update list command output
* Rename the config entry API client methods.
* Use renamed apis
* Implement config write tests
Stub the others with the noTabs tests.
* Change list output format
Now just simply output 1 line per named config
* Add config read tests
* Add invalid args write test.
* Add config delete tests
* Add config list tests
* Add connect enable tests
* Update some CLI commands to use CAS ops
This also modifies the HTTP API for a write op to return a boolean indicating whether the value was written or not.
* Fix up the HTTP API CAS tests as I realized they weren’t testing what they should.
* Update config entry rpc tests to properly test CAS
* Fix up a few more tests
* Fix some tests that using ConfigEntries.Apply
* Update config_write_test.go
* Get rid of unused import
