Before this, the Terraform Puppet provisioner would error out in a
confusing way if the type attribute in a connection block was not given.
Apparently an omitted type leads to type having a value "" which must be
then assumed to mean "ssh".
Fixes#23004
`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.
Our documentation for how to contribute was in quite a state of disrepair,
with some documents still describing things as they were before moving
providers into separate repositories, others making assumptions about
Go development that are no longer true in modules mode, and so forth.
This is an attempt at a reset to a good state that should work with the
codebase as it currently stands, and should hopefully serve as a basis
for iterative improvement from here.
These new instructions lean primarily on standard Go toolchain usage and
instruct using the Makefile only for some Terraform-specific situations
that the Go toolchain does not automatically handle. The idea here is that
this direct usage of primary commands in the Go toolchain is less likely
to be broken by changes in future Go releases, and should be immediately
familiar to anyone who has experience with Go development.
* 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.
A very common question since we launched the two repetition constructs
is how to deal with situations where the input data structure doesn't
match one-to-one with the desired configuration.
This adds some full worked examples of two common situations that have
come up in questions. To avoid adding a lot of extra content to the
already-large "expressions" and "resources" pages, the main bulk of this
new content lives with the relevant functions themselves as a full example
of one thing they are good for, and then we'll link to them from the two
general documentation sections where folks are likely to be reading when
they encounter the problem.
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.
We previously deferred this to Validate, but all of our operations require
a valid set of variables and so checking this up front makes it more
obvious when a call into Terraform Core from the CLI layer isn't
populating variables correctly, instead of having it fail downstream
somewhere.
It's the caller's responsibility to ensure that it has collected values
for all of the variables in some way before calling NewContext, because
in the main case driven by the CLI there are many different places that
variable values can be collected from and so handling the main user-facing
validation in the CLI allows us to return better error messages that take
into account which way a variable is (or is not) being set.
* 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.

Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.
This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.
For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.
