Change "Downloading" to 'Initializing" to match the provider loading
dialog.
List each module being loaded.
If a regisry module is being downloaded, list the registry host, and the
version discovered.
Show the source string from the config that is being fetched, rather
than the go-getter url. The full source can be found in the logs for
debugging.
Add much more extensive logging
We can remove the AllowAny option which is no longer used, and providers
don't need to be connected to their resources at this stage, since that
will happen in the ProviderTransformer.
Now that providers in the graph can adopt resources without an explicit
provider, there's no need to add the implicit configs to the module.Tree
when loading.
Simplify the MissingProviderTransformer so that it only adds missing
providers at the root level. There's no need for the multitple providers
added at every level of the path
ParentProviderTransformer then only needs to connect providers with the
equivalent type at the root level.
The the grandChild missing test has a provider declared in a child
module which is missing in a grandchildmodule. Verify that the
grandchild gets connected to the child provider, and they all are
connected to the root providers.
Update some test outputs to match the expected behavior of only adding
missing providers at the root level.
The CloserProviderTransformer requires that the resources be connected
to their provider first, so that it cen get the correct dependencies,
and adding the ProviderTransformer changed the test output slightly.
This turned out to be a big messy commit, since the way providers are
referenced is tightly coupled throughout the code. That starts to unify
how providers are referenced, using the format output node Name method.
Add a new field to the internal resource data types called
ResolvedProvider. This is set by a new setter method SetProvider when a
resource is connected to a provider during graph creation. This allows
us to later lookup the provider instance a resource is connected to,
without requiring it to have the same module path.
The InitProvider context method now takes 2 arguments, one if the
provider type and the second is the full name of the provider. While the
provider type could still be parsed from the full name, this makes it
more explicit and, and changes to the name format won't effect this
code.
The first step in only using the required provider nodes in a graph is
to be able to specifically add them from the configuration.
The MissingProviderTransformer was previously responsible for adding
all providers. Now it is really just adding any that are missing from
the config.
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.
This allows the user to customize the location where Terraform stores
the files normally placed in the ".terraform" subdirectory, if e.g. the
current working directory is not writable.
This keeps CustomizeDiff from being defined on data sources, where it
would be useless. We just catch this in InternalValidate like the rest
of the CRUD functions that are not used in data sources.
Added some more detailed comments to CustomizeDiff's comments. The new
comments detail how CustomizeDiff will be called in the event of
different scenarios like creating a new resource, diffing an existing
one, diffing an existing resource that has a change that requires a new
resource, and destroy/tainted resources.
Also added similar detail to ForceNew in ResourceDiff.
This should help mitigate any confusion that may come up when using
CustomizeDiff, especially in the ForceNew scenario when the second run
happens with no state.
Needed to add more cases to support value comparison exceptions that the
rest of TF expects to work (this fixes tests in various places).
Also moved things to a switch block so that it's a little more compact.
A diff new needs to pass basic value checks to be considered the
"same". Several provisions have been added to ensure that the list, set,
and RequiresNew behaviours that have needed some exceptions in the past
are preserved in this new logic.
This ensures that we are checking for value equality as much as
possible, which will be more important when we transition to the
possibility of diffs being sourced from external data.
setDiff does not make use of its new parameter anymore, so it has been
removed. Also, as there is no more SetDiff (exported) function, mentions
of that have been removed from comments too.
This fixes nil pointer issues that could come up if an invalid key was
referenced (ie: not one in the schema). Also ships a helper validation
function to streamline things.
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.
The old comments said that this interface was API compatible with
terraform.ResourceProvider's Diff method - with the addition of passing
down meta to it, this is no longer the case.
Not too sure if this is really a big deal - schema.Resource never fully
implemented terraform.ResourceProvider, from what I can see, and the
path from Provdier.Diff to Resource.Diff is still pretty clear. Just
wanted to remove an outdated comment.
This could panic if we sent a parent that was actually longer than the
child (should almost never come up, but the guard will make it safe
anyway).
Also fixed a slice style lint warning in UpdatedKeys.
