* command/show: fixing bugs in modulecalls
jsonconfig and jsonplan both had subtle bugs with the logic for
marshaling module calls that only showed up when multiple modules were
referenced. This PR fixes those bugs and extends the existing tests to
include multiple modules.
* sort all the things, mostly for tests
* command/jsonconfig: provider config marshaling enhancements
This PR fixes a bug wherein the keys in "provider_config" were the
"addrs.ProviderConfig", and therefore being overwritten for each module,
instead of the intended "addrs.AbsProviderConfig".
We realized that there was still opportunity for ambiguity, for example
if a user made a provider alias that was the same name as a module, so
we opted to use the syntax `modulename:providername(.provideralias)`
* command/json*: fixed a bug where we were attempting to lookup schemas
with the provider name, instead of provider type.
* command/show: add "module_version" to "module_calls" in config portion
of `terraform show`.
Also extended the `terraform show -json` test to run `init` so we could
add examples with modules. This does _not_ test the "module_version"
yet, but it _did_ help expose a bug in jsonplan where modules were
duplicated. This is also fixed in this PR.
* command/jsonconfig: rename version to version_constraint and
resolved_source to source.
* command/jsonconfig: display module variables in config output
The tests have been updated to reflect this change.
* command/jsonconfig: properly handle variables with nil defaults
* command/jsonplan:
- add variables to plan output
- print known planned values for resources
Previously, resource attribute values were only displayed if the values
were wholly known. Now we will filter the unknown values out of the
change and print the known values.
* command/jsonstate: added depends_on and tainted fields
* command/show: update tests to reflect added fields
We now require a provider to populate all of its defaults -- including
unknown value placeholders -- during PlanResourceChange. That means the
mock provider for testing "terraform show -json" must now manage the
population of the computed "id" attribute during plan.
To make this logic a little easier, we also change the ApplyResourceChange
implementation to fill in a non-null id, since that makes it easier for
the mock PlanResourceChange to recognize when it needs to populate that
default value during an update.
* command/jsonplan: sort resources by address
* command/show: extend test case to include resources with count
* command/json*: document resource ordering as consistent but undefined
* command/show: properly marshal attribute values to json
marshalAttributeValues in jsonstate and jsonplan packages was returning
a cty.Value, which json/encoding could not marshal. These functions now
convert those cty.Values into json.RawMessages.
* command/jsonplan: planned values should include resources that are not changing
* command/jsonplan: return a filtered list of proposed 'after' attributes
Previously, proposed 'after' attributes were not being shown if the
attributes were not WhollyKnown. jsonplan now iterates through all the
`after` attributes, omitting those which are not wholly known.
The same was roughly true for after_unknown, and that structure is now
correctly populated. In the future we may choose to filter the
after_unknown structure to _only_ display unknown attributes, instead of
all attributes.
* command/jsonconfig: use a unique key for providers so that aliased
providers don't get munged together
This now uses the same "provider" key from configs.Module, e.g.
`providername.provideralias`.
* command/jsonplan: unknownAsBool needs to iterate through objects that are not wholly known
* command/jsonplan: properly display actions as strings according to the RFC,
instead of a plans.Action string.
For example:
a plans.Action string DeleteThenCreate should be displayed as ["delete",
"create"]
Tests have been updated to reflect this.
* command/jsonplan: return "null" for unknown list items.
The length of a list could be meaningful on its own, so we will turn
unknowns into "null". The same is less likely true for maps and objects,
so we will continue to omit unknown values from those.
* command/show: added test scaffold for json output
More test cases will be added once the basic shape of the tests is
validated.
- command/json* packages now sort resources by address, matching
behavior elsewhere
- using cmp in tests instead of reflect.DeepEqual for the diffs
- updating expected output in tests to match sorting
