The formatter in `command/format/state.go`, when formatting a resource
with an aliased provider, was looking for a schema with the alias (ie,
test.foo), but the schemas are only listed by provider type (test).
Update the state formatter to lookup schemas by provider type only.
Some of the show tests (and a couple others) were not properly cleaning
up the created tmpdirs, so I fixed those. Also, the show tests are using
a statefile named `state.tfstate`, but were not passing that path to the
show command, so we were getting some false positives (a `show` command
that returns `no state` exits 0).

* deps: bump terraform-config-inspect library
* configs: parse `version` in new required_providers block
With the latest version of `terraform-config-inspect`, the
required_providers attribute can now be a string or an object with
attributes "source" and "version". This change allows parsing the
version constraint from the new object while ignoring any given source attribute.
* command: use backend config from state when backend=false is used.
When a user runs `terraform init --backend=false`, terraform should
inspect the state for a previously-configured backend, and use that
backend, ignoring any backend config in the current configuration. If no
backend is configured or there is no state, return a local backend.
Fixes#16593
Clear any Dependencies if there is an entry matching a `state mv` from
address. While stale dependencies won't directly effect any current
operations, clearing the list will allow them to be recreated in their
entirety during refresh. This will help future releases that may rely
solely on the pre-calculated dependencies for destruction ordering.
* configs: move ProviderConfigCompact[Str] from addrs to configs
The configs package is aware of provider name and type (which are the
same thing today, but expected to be two different things in a future
release), and should be the source of truth for a provider config
address. This is an intermediate step; the next step will change the returned types to something based in the configs package.
* command: rename choosePlugins to chooseProviders to clarify scope of function
* use `Provider.LegacyString()` (instead of `Provider.Type`) consistently
* explicitly create legacy-style provider (continuing from above change)
When warnings appear in isolation (not accompanied by an error) it's
reasonable to want to defer resolving them for a while because they are
not actually blocking immediate work.
However, our warning messages tend to be long by default in order to
include all of the necessary context to understand the implications of
the warning, and that can make them overwhelming when combined with other
output.
As a compromise, this adds a new CLI option -compact-warnings which is
supported for all the main operation commands and which uses a more
compact format to print out warnings as long as they aren't also
accompanied by errors.
The default remains unchanged except that the threshold for consolidating
warning messages is reduced to one so that we'll now only show one of
each distinct warning summary.
Full warning messages are always shown if there's at least one error
included in the diagnostic set too, because in that case the warning
message could contain additional context to help understand the error.
The configs package is aware of provider name and type (which are the
same thing today, but expected to be two different things in a future
release), and should be the source of truth for a provider config
address.
* huge change to weave new addrs.Provider into addrs.ProviderConfig
* terraform: do not include an empty string in the returned Providers /
Provisioners
- Fixed a minor bug where results included an extra empty string
If a state mv target happens to be a resource that doesn't exist, allow
the creation of the new resource inferring the EachMode from the target
address.
* terraform/context: use new addrs.Provider as map key in provider factories
* added NewLegacyProviderType and LegacyString funcs to make it explicit that these are temporary placeholders
This PR introduces a new concept, provider fully-qualified name (FQN), encapsulated by the `addrs.Provider` struct.
Some of our warnings are produced in response to particular configuration
constructs which might appear many times across a Terraform configuration.
To avoid the warning output dwarfing all of the other output, we'll use
ConsolidateWarnings to limit each distinct warning summary to appear at
most twice, and annotate the final one in the sequence with an additional
paragraph noting that some number of them have been hidden.
This is intended as a compromise to ensure that these warnings are still
seen and noted but to help ensure that we won't produce so many of them
as to distract from other output that appears alongside them.
This applies only to warnings relating to specific configuration ranges;
errors will continue to be shown individually, and sourceless warnings
(which are rare in Terraform today) will likewise remain ungrouped because
they are less likely to be repeating the same statement about different
instances of the same problem throughout the configuration.
Meta.backendConfig was incorrectly treating the second return value from
loadBackendConfig as if it were go "error" rather than
tfdiags.Diagnostics, which in turn meant that it would treat warnings like
errors.
This had confusing results because it still returned that
tfdiags.Diagnostics value in its own diagnostics return value, causing the
caller to see warnings even though the backendConfig function had taken
the error codepath.
We have a special treatment for multi-line strings that are being updated
in-place where we show them across multiple lines in the plan output, but
we didn't use that same treatment for rendering multi-line strings in
isolation such as when they are being added for the first time.
Here we detect when we're rendering a multi-line string in a no-change
situation and render it using the diff renderer instead, using the same
value for old and new and thus producing a multi-line result without any
diff markers at all.
This improves consistency between the change and no-change cases, and
makes multi-line strings (such as YAML in block mode) readable in all
cases.
The DestroyEdgeTransformer cannot determine ordering from the graph when
the destroyers are from orphaned resources, because there are no
references to resolve. The new stored Dependencies provides what we need
to connect the instances in this case.
We also add the StateDependencies method directly in the
GraphNodeResourceInstance interface, since all instances already
implement this, and we don't need another optional interface to check.
The old code in DestroyEdgeTransformer may no longer be needed in the
long run, but that can be determined separately, since too many of the
tests start with an incomplete state and rely on the Dependencies being
determined from the configuration alone.
This "Plan" type, along with the other types it directly or indirectly
embeds and the associated functions, are adaptations of the
flatmap-oriented plan renderer logic from Terraform 0.11 and prior.
The current diff rendering logic is in diff.go, and so the contents of the
plan.go file are defunct apart from the DiffActionSymbol function that
both implementations share. Therefore here we move DiffActionSymbol into
diff.go and then remove plan.go entirely, in the interests of dead code
removal.
During the Terraform 0.12 work we briefly had a partial update of the old
Terraform 0.11 (and prior) diff renderer that could work with the new
plan structure, but could produce only partial results.
We switched to the new plan implementation prior to release, but the
"terraform show" command was left calling into the old partial
implementation, and thus produced incomplete results when rendering a
saved plan.
Here we instead use the plan rendering logic from the "terraform plan"
command, making the output of both identical.
Unfortunately, due to the current backend architecture that logic lives
inside the local backend package, and it contains some business logic
around state and schema wrangling that would make it inappropriate to move
wholesale into the command/format package. To allow for a low-risk fix to
the "terraform show" output, here we avoid some more severe refactoring by
just exporting the rendering functionality in a way that allows the
"terraform show" command to call into it.
In future we'd like to move all of the code that actually writes to the
output into the "command" package so that the roles of these components
are better segregated, but that is too big a change to block fixing this
issue.
We need to be able to reference all possible dependencies for ordering
when the configuration is no longer present, which means that absolute
addresses must be used. Since this is only to recreate the proper
ordering for instance destruction, only resources addresses need to be
listed rather than individual instance addresses.
`marshalPlannedValues` builds a map of modules to their children in
order to output the resource changes in a tree. The map was built from
the list of resource changes. However if a module had no resources
itself, and only called another module (a very normal case), that module
would not get added to the map causing none of its children to be
output in `planned_values`.
This PR adds a walk up through a given module's ancestors to ensure that
each module, even those without resources, would be added.
* command/validate: output a warning if unused flags are set
The -var and -var-file command line flags are accepted, but not used,
in `terraform validate`. This PR adds a warning for users who set either
of those flags, so they know that setting them has no effect.
Terraform Core expects all variables to be set, but for some ancillary
commands it's fine for them to just be set to placeholders because the
variable values themselves are not key to the command's functionality
as long as the terraform.Context is still self-consistent.
For such commands, rather than prompting for interactive input for
required variables we'll just stub them out as unknowns to reflect that
they are placeholders for values that a user would normally need to
provide.
This achieves a similar effect to how these commands behaved before, but
without the tendency to produce a slightly invalid terraform.Context that
would fail in strange ways when asked to run certain operations.
During the 0.12 work we intended to move all of the variable value
collection logic into the UI layer (command package and backend packages)
and present them all together as a unified data structure to Terraform
Core. However, we didn't quite succeed because the interactive prompts
for unset required variables were still being handled _after_ calling
into Terraform Core.
Here we complete that earlier work by moving the interactive prompts for
variables out into the UI layer too, thus allowing us to handle final
validation of the variables all together in one place and do so in the UI
layer where we have the most context still available about where all of
these values are coming from.
This allows us to fix a problem where previously disabling input with
-input=false on the command line could cause Terraform Core to receive an
incomplete set of variable values, and fail with a bad error message.
As a consequence of this refactoring, the scope of terraform.Context.Input
is now reduced to only gathering provider configuration arguments. Ideally
that too would move into the UI layer somehow in a future commit, but
that's a problem for another day.
* command/jsonstate: properly marshal deposed resources
This PR addresses 2 issues: `show -json` would crash if there was not a
`Current` `states.ResourceInstance` for a given resource, and `deposed`
resource instances were not shown at all.
