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.
Replace the old mock provider test functions with modern equivalents.
There were a lot of inconsistencies in how they were used, so we needed
to update a lot of tests to match the correct behavior.
pathorcontents was solely used by the gcs backend. I moved the function
into the backend package so it could still be used by other backends for
good measure.
helper/copy CopyDir was used heavily in tests. It differes from
internal/copydir in a few ways, the main one being that it creates the
dst directory while the internal version expected the dst to exist
(there are other differences, which is why I did not just switch tests
to using internal's CopyDir).
I moved the CopyDir func from helper/copy into command_test.go; I could
also have moved it into internal/copy and named it something like
CreateDirAndCopy so if that seems like a better option please let me
know.
helper/copy/CopyFile was used in a couple of spots so I moved it into
internal, at which point I thought it made more sense to rename the
package copy (instead of copydir).
There's also a `go mod tidy` included.
If sensitivity changes, we have an update plan,
but should avoid communicating with the provider
on the apply, as the values are equal (and otherwise
a NoOp plan)
* remove unused code
I've removed the provider-specific code under registry, and unused nil
backend, and replaced a call to helper from backend/oss (the other
callers of that func are provisioners scheduled to be deprecated).
I also removed the Dockerfile, as our build process uses a different
file.
Finally I removed the examples directory, which had outdated examples
and links. There are better, actively maintained examples available.
* command: remove various unused bits
* test wasn't running
* backend: remove unused err
When the sensitivity has changed, we want to write to
state and also display to the user that the sensitivity
has changed, so make this an update action. Also
clean up some assignments, since Contains traverses the val
anyway, this is a little tighter.
If an entire block is marked sensitive (possibly because it is of type
NestedSet) and results in replacement of the resource, we should render
the standard "forces replacement" text after the opening line of the
block.
Auditing the graph builder to remove unused transformers (planning does
not need to close provisioners for example), and re-order them. While
many of the transformations are commutative, using the same order
ensures the same behavior between operations when the commutative
property is lost or changed.
Outputs were not being evaluated during import, because it was not added
to the walk filter.
Remove any unnecessary walk filters from all the Execute nodes.
If a value rendered for the diff is sensitive and results in replacement
of the resource, we should render the standard "forces replacement" text
after the "(sensitive)" value display.
We do not currently need to evaluate module variables in order to
import a resource.
This will likely change once we can select the import provider
automatically, and have a more dynamic method for dispatching providers
to module instances. In the meantime we can avoid the evaluation for now
and prevent a certain class of import errors.
