Terraform used to provide empty diffs to the provider when calculating
`ignore_changes`, which would cause some DiffSuppressFunc to fail, as
can be seen in #18209.
Verify that this is no longer the case in 0.12
Booleans in the legacy form were stored as strings, and can appear as
the incorrect type in the new type system.
Unset fields in sets also might show up erroneously in diffs, with
equal old and new values.
This work was done against APIs that were already changed in the branch
before work began, and so it doesn't apply to the v0.12 development work.
To allow v0.12 to merge down to master, we'll revert this work out for now
and then re-introduce equivalent functionality in later commits that works
against the new APIs.
Various things drifted since these tests were originally written. This
catches them up to the latest implementations of state decoding,
upgrading, etc.
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.
The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.
The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.
Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.
* builtin/providers: implement terraform remote state datasource as providers.Interface
* append and return diags separately (to match the idiomatic usage
elsewhere in Terraform)
* diagnostic summary style improvements
* update tests to pass config to schema.CoerceValue
* trust that the schema will be enforced and there is no need to check
that a given attribute exists
* added dataSourceRemoteStateGetSchema() (effectively replacing a
function that was inappropriately removed) for consistency with other
terraform providers
* builtin/provider terraform test: added InternalValidate() test for dataSourceRemoteStateGetSchema
The new config loader requires some steps to happen in a different
order, particularly in regard to knowing the schema in order to
decode the configuration.
Here we lean directly on the configschema package, rather than
on helper/schema.Backend as before, because it's generally
sufficient for our needs here and this prepares us for the
helper/schema package later moving out into its own repository
to seed a "plugin SDK".
The `remote` backend config contains an attribute that is defined as a `*schema.Set`, but currently only `string` values are accepted as the `config` attribute is defined as a `schema.TypeMap`.
Additionally the `b.Validate()` method wasn’t called to prevent a possible panic in case of unexpected configurations being passed to `b.Configure()`.
This commit is a bit of a hack to be able to support this in the 0.11 series. The 0.12 series will have proper support, so when merging 0.12 this should be reverted again.
The "terraform" provider was previously split out into its own repository,
but that turned out to be a mistake due to how tightly it depends on
aspects of Terraform Core.
Here we prepare to bring it back into the core repository by reorganizing
the directory layout to conform with what's expected there.
Added a list SetNew test to try and reproduce issues testing diff
customization with the Nomad provider. We are running into "diffs didn't
match during apply", with the plan diff exhibiting a strange
off-by-one-type error in a list diff:
datacenters.#: "1" => "2"
datacenters.0: "dc1" => "dc2"
datacenters.1: "" => "dc3"
datacenters.2: "" => "dc3"
The test here does not reproduce that issue, unfortunately, but should
help pinpoint the root cause through elimination.
Restoring the naming of this field in the resource back to
CustomizeDiff, as this is generally more descriptive of the process
that's happening, despite the lengthy name.
To keep with the current convention of most other schema.Resource
functional fields being fairly short, CustomizeDiff has been changed to
"Review". It would be "Diff", however it is already used by existing
functions in schema.Provider and schema.Resource.
It's alive! CustomizeDiff logic now has been inserted into the diff
process. The test_resource_with_custom_diff resource provides some basic
testing and a reference implementation.
There should now be plenty of test coverage for this feature via the
tests added for ResourceDiff, and the basic test added to the
schemaMap.Diff test, and the test resource, but more can be added to
test any specific case that comes up otherwise.
All providers moved to new repos.
Added README, which also serves to preserve the directory in git in
cacse we want to add select providers back into core (e.g. null,
template, test)
We are moving away from using the term "environment" to describe separate
named states for a single config, using "workspace" instead. The old
attribute name remains supported for backward compatibility, but is
marked as deprecated.
* Data Source support for Resource Group
* Better message for mismatching locations.
* Reuse existing read code
* Adds documentation
* Adds test
* Adds a function for composing ID strings
* Change location to computed.
