Fixes#10439
When a CBD resource depends on a non-CBD resource, the non-CBD resource
is auto-promoted to CBD. This was done in
cf3a259. This PR makes it so that we
also set the config CBD to true. This causes the proper runtime
execution behavior to occur where we depose state and so on.
So in addition to simple graph edge tricks we also treat the non-CBD
resources as CBD resources.
Fixes#10338
The destruction step for a resource was included the deposed resources
for _all_ resources with that name (ignoring the "index"). For example:
`aws_instance.foo.0` was including destroying deposed for
`aws_instance.foo.1`.
This changes the config to the deposed transformer to properly include
that index.
This change includes a larger change of changing `stateId` to include
the index. This affected more parts but was ultimately the issue in
question.
When referencing a list of maps variable from within a resource, only
the first list element is included the plan. This is because GetRaw
can't access the interpolated values. Add some tests to document this
behavior for both Get and GetRaw.
Fixes#10313
The new graph wasn't properly recording resource dependencies to a
specific index of itself. For example: `foo.bar.2` depending on
`foo.bar.0` wasn't shown in the state when it should've been.
This adds a test to verify this and fixes it.
ResourceAddr.Mode wasn't properly set when moving a module, so data
sources would lose the "data." prefix when their module was moved within
the State.
ResourceConfig.Get could previously return (nil, true) when looking up
an interpolated map in a list because of the indexing ambiguity. Make
sure we test that a non-existent value always returns false.
It makes for sense for this to happen in State.prune(). Also move a
redundant pruning from ResourceState.init, and make sure
ResourceState.prune is called from the parent's prune method.
Fixes a case where ResourceConfig.get inadvertently returns a nil value.
Add an integration test where assigning a map to a list via
interpolation would panic.
Setting variables happens before context validation, so it's possible
that the user could be trying to set an incorrect variable type to a
map. Return a useful error rather than panicking.
Ensure that each instance of BasucGraphBuilder gets a name corresponding
to the Builder which created it. This allows us to differentiate the
graphs in the logs.
This doesn't cause any practical issues as far as I'm aware (couldn't
get any test to fail), but caused shadow errors since it wasn't matching
the prior behavior.
Fixes#10122
The simple fix was that we forgot to close `ReadDataApply` for the
provider. But I've always felt that this section of the code was brittle
and I wanted to put in a more robust solution. The `shadow.Close` method
uses reflection to automatically close all values.
People with `uuid()` usage in their configurations would receive shadow
errors every time on plan because the UUID would change.
This is hacky fix but I also believe correct: if a shadow error contains
uuid() then we ignore the shadow error completely. This feels wrong but
I'll explain why it is likely right:
The "right" feeling solution is to create deterministic random output
across graph runs. This would require using math/rand and seeding it
with the same value each run. However, this alone probably won't work
due to Terraform's parallelism and potential to call uuid() in different
orders. In addition to this, you can't seed crypto/rand and its unlikely
that we'll NEVER use crypto/rand in the future even if we switched
uuid() to use math/rand.
Therefore, the solution is simple: if there is no shadow error, no
problem. If there is a shadow error and it contains uuid(), then ignore
it.
The method marks the start of a set of operations on the Graph, with
extra information optionally provided in the second paramter. This
returns a function with a single End method to mark the end of the set
in the logs.
Refactor the existing graph Begin/End Operation calls to use this single
method. Remove the *string types in the marshal structs, these are
strictly informational and don't need to differentiate empty vs unset
strings.
Add calls to DebugOperation for each step while building the graph.
