Using markedPlannedNewVal caused many test
failures with ignoreChanges, and I noted plannedNewVal
itself is modified in the eval_diff. plannedNewVal
is now marked closer to the change where it needs it.
There is also a test fixture update to remove interpolation warnings.
Mark sensitivity on a value. However, when the value is encoded to send to the
provider to produce a changeset we must remove the marks, so unmark the value
and remark it with the saved path afterwards
When rendering a diff between current state and projected state, we only
show resources and outputs which have changes. However, we show a full
structural diff for these values, which includes all attributes and
blocks for a changed resource or output. The result can be a very long
diff, which makes it difficult to verify what the changed fields are.
This commit adds an experimental concise diff renderer, which suppresses
most unchanged fields, only displaying the most relevant changes and
some identifying context. This means:
- Always show all identifying attributes, initially defined as `id`,
`name`, and `tags`, even if unchanged;
- Only show changed, added, or removed primitive values: `string`,
`number`, or `bool`;
- Only show added or removed elements in unordered collections and
structural types: `map`, `set`, and `object`;
- Show added or removed elements with any surrounding unchanged elements
for sequence types: `list` and `tuple`;
- Only show added or removed nested blocks, or blocks with changed
attributes.
If any attributes, collection elements, or blocks are hidden, a count
is kept and displayed at the end of the parent scope. This ensures that
it is clear that the diff is only displaying a subset of the resource.
The experiment is currently enabled by default, but can be disabled by
setting the TF_X_CONCISE_DIFF environment variable to 0.
In refactoring the force push code when implementing force push
for the Terraform remote backend, a bug was introduced that
meant that backends that don't implement the EnableForcePush
method would still have their state validated. This commit
fixes that, and adds test coverage such that there is a separate
mockRemoteClient that has this method implemented.
When applying a plan, a forced CreateBeforeDestroy may not be set during
the apply walk when downstream resources are no longer present in the
graph. We still need to stick to that plan, and both the
NodeApplyableResourceInstance EvalTree and the individual Eval nodes
need to operate on that planned value.
Ensure that we always check for an existing plan when determining
CreateBeforeDestroy status. This must happen in 2 different code paths
due to the eval node pattern currently in-use. Future refactoring may be
able to unify these code-paths to make this less fragile.
If a resource is forced CreateBeforeDestroy from a dependent resource,
and that dependent has no changes, the plan is changed from
CreateThenDelete to DeleteThenCreate causing an apply error.
One of the tenants of the graph transformations is that resource destroy
nodes can only be ordered relative to other resources, and can't be
referenced directly. This was broken by the module close node which
naively connected to all module nodes, creating cycles in some cases
when edges are reversed from CreateBeforeDestroy.
A few users have recently been confused about the purpose of the
required_providers objects, adding provider configuration parameters in
addition to version and source. This previously did not cause an error
so would result in a confusingly distant failure.
This commit adds a single diagnostic for any required_providers object
which includes attributes other than version or source.
In addition to the directories previously listed, Terraform looks in the
CLI config directory ($HOME/.terraform.d/plugins on macOS/Linux/UNIX,
and %APPDATA%/terraform.d/plugins on Windows). List this in the
documentation for clarity.
We also add a note about the working directory relative "vendor"
location, ./terraform.d/plugins.
This commit refactors NodeApplyableOutput and NodeDestroyableOutput into
the new Execute() pattern, collapsing the functions in eval_output.go
into one place.
I also reverted a recent decision to have Execute take a _pointer_ to a
walkOperation: I was thinking of interfaces, not constant bytes, so all
it did was cause problems.
And finally I removed eval_lang.go, which was unused.
Due to a recent update to OS X, this is necessary
so that the correct working directory is saved,
so that methods like Path() on the e2e binary
will return the correct value
This commit continues the overall EvalNode removal project.
Something to note: the NodeRefreshableDataResourceInstance's Execute()
function is intentionally refactored in the bare minimum,
hardly-a-refactor style, because we have another ongoing project which
aims to remove NodeRefreshable*s. It is not worth the effort at this
time. We may revisit this decision in the future.
It doesn't make sense for a built-in provider to appear in a lock file
because built-in providers have no version independent of the version of
Terraform they are compiled into.
We also exclude legacy providers here, because they were supported only
as a transitional aid to enable the Terraform 0.13 upgrade process and
are not intended for explicit selection.
The provider installer will, once it's updated to understand dependency
locking, use this concept to decide which subset of its selections to
record in the dependency lock file for reference for future installation
requests.
This is an initial implementation of writing locks back to a file on disk.
This initial implementation is incomplete because it does not write the
changes to the new file atomically. We'll revisit that in a later commit
as we return to polish these codepaths, once we've proven out this
package's design by integrating it with Terraform's provider installer.
This is the initial implementation of the parser/decoder portion of the
new dependency lock file handler. It's currently dead code because the
caller isn't written yet. We'll continue to build out this functionality
here until we have the basic level of both load and save functionality
before introducing this into the provider installer codepath.
The version constraint parser allows "~> 2", but it behavior is identical
to "~> 2.0". Due to a quirk of the constraint parser (caused by the fact
that it supports both Ruby-style and npm/cargo-style constraints), it
ends up returning "~> 2" with the minor version marked as "unconstrained"
rather than as zero, but that means the same thing as zero in this context
anyway and so we'll prefer to stringify as "~> 2.0" so that we can be
clearer about how Terraform is understanding that version constraint.
