DecoderSpec may be called many times, and deeply recursive calls are
expensive. Since we cannot synchronize the Blocks themselves due to them
being copied in parts of the code, we use a separate cache to store the
generated Specs.
A few tests were inadvertently renamed, causing them to be be skipped.
For some reason this is not caught by the `vet` pass that happens during
normal testing.
When an attribute's sensitivity changes, but its value remains the same,
we consider this an update operation for the plan. This commit updates
the diff renderer to match this, detecting and displaying the change in
sensitivity.
Previously, the renderer would detect no changes to the value of the
attribute, and consider it a no-op action. This resulted in suppression
of the attribute when the plan is in concise mode.
This is achieved with a new helper function, ctyEqualValueAndMarks. We
call this function whenever we want to check that two values are equal
in order to determine whether the action is update or no-op.
The ProviderConfigTransformer was using only the provider FQN to attach
a provider configuration to the provider, but what it needs to do is
find the local name for the given provider FQN (which may not match the
type name) and use that when searching for matching provider
configuration.

This will also be backported to the v0.13 branch.
The legacy tests never had to account for outputs in the plan. This path
is not used outside of old builtin test provider, so just work around
the output changes until we remove this completely.
The upgrade requirements for this release are considerably more modest
than for Terraform v0.13, so this time we just have some notes about a
few changes in behavior that may be impactful to some users.
This first pass is intended to be included as part of a forthcoming beta
testers' guide as we begin the v0.14 beta testing period. We will make
further changes to this upgrade guide based on feedback from those who
participate in the beta process.
Note that this upgrade guide is not intended as release marketing material
and so its presentation is focused on addressing concerns users might
encounter while upgrading. We'll share highlights from the release in
other contexts, such as the changelog and in the product blog.
The state is not loaded here with any marks, so we cannot rely on marks
alone for equality comparison. Compare both the state and the
configuration sensitivity before creating the OutputChange.
Since root outputs can now use the planned changes, we can directly
insert the correct applyable or destroyable node into the graph during
plan and apply, and it will remove the outputs if they are being
destroyed.
This builds on an experimental feature in the underlying cty library which
allows marking specific attribtues of an object type constraint as
optional, which in turn modifies how the cty conversion package handles
missing attributes in a source value: it will silently substitute a null
value of the appropriate type rather than returning an error.
In order to implement the experiment this commit temporarily forks the
HCL typeexpr extension package into a local internal/typeexpr package,
where I've extended the type constraint syntax to allow annotating object
type attributes as being optional using the HCL function call syntax.
If the experiment is successful -- both at the Terraform layer and in
the underlying cty library -- we'll likely send these modifications to
upstream HCL so that other HCL-based languages can potentially benefit
from this new capability.
Because it's experimental, the optional attribute modifier is allowed only
with an explicit opt-in to the module_variable_optional_attrs experiment.
We record output changes in the plan, but don't currently use them for
anything other than display. If we have a wholly known output value
stored in the plan, we should prefer that for apply in order to ensure
consistency with the planned values. This also avoids cases where
evaluation during apply cannot happen correctly, like when all resources
are being removed or we are executing a destroy.
We also need to record output Delete changes when the plan is for
destroy operation. Otherwise without a change, the apply step will
attempt to evaluate the outputs, causing errors, or leaving them in the
state with stale values.
Previously we were just letting hclwrite do its default formatting
behavior here. The current behavior there isn't ideal anyway -- it puts
big data structures all on one line -- but even ignoring that our goal
for this file format is to keep things in a highly-normalized shape so
that diffs against the file are clear and easy to read.
With that in mind, here we directly control how we write that value into
the file, which means that later changes to hclwrite's list/set
presentation won't affect it, regardless of what form they take.
This includes both the main documentation about the lock file itself and
changes to related documentation about Terraform commands that interact
with the lock file.
We will likely continue to update this first pass of documentation as we
get feedback and questions during the prerelease period.
This command is intended to help support situations where Terraform is
configured to use only local mirrors for provider installation and so the
normal "terraform init" flow would not have direct access to the official
package checksums published in the origin registry.
The intended workflow here is to use this command only when adding a new
provider or changing an existing provider's version in the configuration,
to augment the lock file with all of the checksums required to verify
the provider across a variety of different platforms. Once this command
has recorded all of the official checksums, future runs of
"terraform init" will verify that provider packages obtained from a local
mirror match with those upstream checksums.
This probably isn't the best UI we could do here, but it's a placeholder
for now just to avoid making it seem like we're ignoring the lock file
and checking for new versions anyway.
This changes the approach used by the provider installer to remember
between runs which selections it has previously made, using the lock file
format implemented in internal/depsfile.
This means that version constraints in the configuration are considered
only for providers we've not seen before or when -upgrade mode is active.
These are helper functions to give the installation UI some hints about
whether the lock file has changed so that it can in turn give the user
advice about it. The UI-layer callers of these will follow in a later
commit.
