When rendering planned output changes, we need to filter the plan's
output changes to ensure that only root module outputs which have
changed are rendered. Otherwise we will render changes for submodule
outputs, and (with concise diff disabled) render unchanged outputs also.
Use a single log writer instance for all std library logging.
Setup the std log writer in the logging package, and remove boilerplate
from test packages.
A cost estimation error does not actually stop a run, so the run was continuing in the background after the cli exits, causing confusion. This change matches the UI 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.
* 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Finally I removed the examples directory, which had outdated examples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 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.
This pull reverts a recent change to backend/local which created two context, one with and one without state. Instead I have removed the state entirely from the validate graph (by explicitly passing a states.NewState() to the validate graph builder).
This changed caused a test failure, which (ty so much for the help) @jbardin discovered was inaccurate all along: the test's call to `Validate()` was actually what was removing the output from state. The new expected test output matches terraform's actual behavior on the command line: if you use -target to destroy a resource, an output that references only that resource is *not* removed from state even though that test would lead you to believe it did.
This includes two tests to cover the expected behavior:
TestPlan_varsUnset has been updated so it will panic if it gets more than one request to input a variable
TestPlan_providerArgumentUnset covers #26035Fixes#26035, #26027
The Consul KV store limits the size of the values in the KV store to 524288
bytes. Once the state reaches this limit Consul will refuse to save it. It is
currently possible to try to bypass this limitation by enable Gzip but the issue
will manifest itself later. This is particularly inconvenient as it is possible
for the state to reach this limit without changing the Terraform configuration
as datasources or computed attributes can suddenly return more data than they
used to. Several users already had issues with this.
To fix the problem once and for all we now split the payload in chunks of 524288
bytes when they are to large and store them separatly in the KV store. A small
JSON payload that references all the chunks so we can retrieve them later and
concatenate them to reconstruct the payload.
While this has the caveat of requiring multiple calls to Consul that cannot be
done as a single transaction as those have the same size limit, we use unique
paths for the chunks and CAS when setting the last payload so possible issues
during calls to Put() should not result in unreadable states.

When the path ends with / (e.g. `path = "tfstate/"), the lock
path used will contain two consecutive slashes (e.g. `tfstate//.lock`) which
Consul does not accept.
This change the lock path so it is sanitized to `tfstate/.lock`.
If the user has two different Terraform project, one with `path = "tfstate"` and
the other with `path = "tfstate/"`, the paths for the locks will be the same
which will be confusing as locking one project will lock both. I wish it were
possible to forbid ending slashes altogether but doing so would require all
users currently having an ending slash in the path to manually move their
Terraform state and would be a poor user experience.

When locking was enabled with the Consul backend and the lock not properly
released, the `terraform force-unlock <lock_id>` command would do nothing as
its implementation would exit early in that case.
It now destroys the session that created the lock and clean both the lock and
the lock-info keys.
A regression test is added to TestConsul_destroyLock() to catch the issue if it
happends again.
