Martin Atkins fc7871c5ee command/import: default provider config in same module
Previously we were defaulting the provider configuration selection to a
provider in the root module inferred from the resource type name.

This is close, but not quite right: we need to _start_ with a provider
configuration in the same module as we're importing into, and then our
provider resolution steps during import graph construction will use that
as a starting point for a walk up the tree to find the nearest matching
configuration (which might eventually still be in the root, but not
necessarily).

Martin Atkins f085af4ba6 command: update "terraform console" for HCL2
This now uses the HCL2 parser and evaluator APIs and evaluates in terms
of a new-style *lang.Scope, rather than the old terraform.Interpolator
type that is no longer functional.

The Context.Eval method used here behaves differently than the
Context.Interpolater method used previously: it performs a graph walk
to populate transient values such as input variables, local values, and
output values, and produces its scope in terms of the result of that
graph walk. Because of this, it is a lot more robust than the prior method
when asked to resolve references other than those that are persisted
in the state.

Martin Atkins 9ca13d5c1d command/validate: make sure diagnostics is always present and an array
Previously an empty diagnostics would appear as "null" in the JSON output,
since that is how encoding/json serializes a nil slice. It's more
convenient for users of dynamic languages to keep the type consistent
in all cases, since they can then just iterate the list without needing a
special case for when it is null.

Martin Atkins c937c06a03 terraform: ugly huge change to weave in new HCL2-oriented types
Due to how deeply the configuration types go into Terraform Core, there
isn't a great way to switch out to HCL2 gradually. As a consequence, this
huge commit gets us from the old state to a _compilable_ new state, but
does not yet attempt to fix any tests and has a number of known missing
parts and bugs. We will continue to iterate on this in forthcoming
commits, heading back towards passing tests and making Terraform
fully-functional again.

The three main goals here are:
- Use the configuration models from the "configs" package instead of the
  older models in the "config" package, which is now deprecated and
  preserved only to help us write our migration tool.
- Do expression inspection and evaluation using the functionality of the
  new "lang" package, instead of the Interpolator type and related
  functionality in the main "terraform" package.
- Represent addresses of various objects using types in the addrs package,
  rather than hand-constructed strings. This is not critical to support
  the above, but was a big help during the implementation of these other
  points since it made it much more explicit what kind of address is
  expected in each context.

Since our new packages are built to accommodate some future planned
features that are not yet implemented (e.g. the "for_each" argument on
resources, "count"/"for_each" on modules), and since there's still a fair
amount of functionality still using old-style APIs, there is a moderate
amount of shimming here to connect new assumptions with old, hopefully in
a way that makes it easier to find and eliminate these shims later.

I apologize in advance to the person who inevitably just found this huge
commit while spelunking through the commit history.

Martin Atkins 4ed06a9227 terraform: HCL2-flavored module dependency resolver
For the moment this is just a lightly-adapted copy of
ModuleTreeDependencies named ConfigTreeDependencies, with the goal that
the two can live concurrently for the moment while not all callers are yet
updated and then we can drop ModuleTreeDependencies and its helper
functions altogether in a later commit.

This can then be used to make "terraform init" and "terraform providers"
work properly with the HCL2-powered configuration loader.

Martin Atkins ebafa51723 command: Various updates for the new backend package API
This is a rather-messy, complex change to get the "command" package
building again against the new backend API that was updated for
the new configuration loader.

A lot of this is mechanical rewriting to the new API, but
meta_config.go and meta_backend.go in particular saw some major
changes to interface with the new loader APIs and to deal with
the change in order of steps in the backend API.
2018-10-16 18:44:26 -07:00
Martin Atkins 5782357c28 backend: Update interface and implementations for new config loader
The new config loader requires some steps to happen in a different
order, particularly in regard to knowing the schema in order to
decode the configuration.

Here we lean directly on the configschema package, rather than
on helper/schema.Backend as before, because it's generally
sufficient for our needs here and this prepares us for the
helper/schema package later moving out into its own repository
to seed a "plugin SDK".

Martin Atkins 618883596a command: remove "terraform push"
The remote API this talks to will be going away very soon, before our next
major release, and so we'll remove the command altogether in that release.

This also removes the "encodeHCL" function, which was used only for
adding a .tfvars-formatted file to the uploaded archive.

Martin Atkins 9a004e3f9d command: "terraform validate" JSON support
In the long run we'd like to offer machine-readable output for more
commands, but for now we'll just start with a tactical feature in
"terraform validate" since this is useful for automated testing scenarios,
editor integrations, etc, and doesn't include any representations of types
that are expected to have breaking changes in the near future.

Martin Atkins bfd9392eb8 command: beginnings of new config loader in "terraform validate"
As part of some light reorganization of our commands, this new
implementation no longer does validation of variables and will thus avoid
the need to spin up a fully-valid context. Instead, its focus is on
validating the configuration itself, regardless of any variables, state,
etc.

This change anticipates us later adding a -validate-only flag to
"terraform plan" which will then take over the related use-case of
checking if a particular execution of Terraform is valid, _including_ the
state, variables, etc.

Although leaving variables out of validate feels pretty arbitrary today
while all of the variable sources are local anyway, we have plans to
allow per-workspace variables to be stored in the backend in future and
at that point it will no longer be possible to fully validate variables
without accessing the backend. The "terraform plan" command explicitly
requires access to the backend, while "terraform validate" is now
explicitly for local-only validation of a single module.

In a future commit this will be extended to do basic type checking of
the configuration based on provider schemas, etc.

Martin Atkins fd5b7b42b8 command: new Meta methods for accessing the new config loader
We need to share a single config loader across all callers because that
allows us to maintain the source code cache we'll use for snippets in
error messages.

Nothing calls this yet. Callers will be gradually updated away from Module
and Config in subsequent commits.

Martin Atkins bd10b84a8e command/format: include source snippets in diagnostics
If we get a diagnostic message that references a source range, and if the
source code for the referenced file is available, we'll show a snippet of
the source code with the source range highlighted.

At the moment we have no cache of source code, so in practice this
codepath can never be visited. Callers to format.Diagnostic will be
gradually updated in subsequent commits.

Sander van Harmelen b1fdbd7db8 Allow enhanced backends to pass custom exit codes
In some cases this is needed to keep the UX clean and to make sure any remote exit codes are passed through to the local process.

The most obvious example for this is when using the "remote" backend. This backend runs Terraform remotely and stream the output back to the local terminal.

When an error occurs during the remote execution, all the needed error information will already be in the streamed output. So if we then return an error ourselves, users will get the same errors twice.

By allowing the backend to specify the correct exit code, the UX remains the same while preserving the correct exit codes.

Fix drift caused from gofmt when running make dev and go 1.11.
A fresh checkout of `origin/master` does not build atm using the `dev`
target because `master` has not been formatted using `gofmt` from Go
1.11 (tis has been the case for a while if you've been running devel).

None of the drift in question is especially new but now that Go 1.11
has been released and gofmt's formatting guidelines have been updated,
it would be *really* nice if the code in `master` reflected the current
tooling in order to avoid having to fight this drift locally.

backend/migrations: migrate the default state

Sander van Harmelen f410a5bb26 backend/migrations: migrate the default state
Certain backends (currently only the `remote` backend) do not support using both the default and named workspaces at the same time.

To make the migration easier for users that currently use both types of workspaces, this commit adds logic to ask the user for a new workspace name during the migration process.

Sander van Harmelen 1696ade924 backend/migrations: check all workspaces
This commit fixes a bug that (in the case of the `local` backend) would only check if the selected workspace had a state when deciding to preform a migration.

When the selected workspace didn’t have a state (but other existing workspace(s) did), the migration would not be preformed and the other workspaces would be ignored.

Sander van Harmelen 179b32d426 Add a `CredentialsForHost` method to disco.Disco
By adding this method you now only have to pass a `*disco.Disco` object around in order to do discovery and use any configured credentials for the discovered hosts.

Of course you can also still pass around both a `*disco.Disco` and a `auth.CredentialsSource` object if there is a need or a reason for that!

Lyle Franklin 26b907387d cli: Remove error on empty outputs when `-json` is set (#11721)
- Fixes #11696
- This changes makes `terraform output -json` return '{}' instead of
  throwing an error about "no outputs defined"
- If `-json` is not set, the user will receive an error as before
  - This UX helps new users to understand how outputs are used
- Allows for easier automation of TF CLI as an empty set of outputs is
  usually acceptable, but any other error from `output` would be
  re-raised to the user.

James Bardin 90a75422fb unlock state in console, import, graph, and push
The state locking improvements for the regular command had the side
effect of locking the state in the console, import, graph and push
commands. Those commands had been updated to get a state via the
Backend.Context method, which locks the state whenever possible, and now
need to call Unlock directly.

Add Unlock calls to all commands that call Context directly.

James Bardin e9a76808df create clistate.Locker interface
Simplify the use of clistate.Lock by creating a clistate.Locker
instance, which stores the context of locking a state, to allow unlock
to be called without knowledge of how the state was locked.

This alows the backend code to bring the needed UI methods to the point
where the state is locked, and still unlock the state from an outer
scope.

Provide a NoopLocker as well, so that callers can always call Unlock
without verifying the status of the lock.

Add the StateLocker field to the backend.Operation, so that the state
lock can be carried between the different function scopes of the backend
code. This will allow the backend context to lock the state before it's
read, while allowing the different operations to unlock the state when
they complete.

2018-02-12 11:56:54 -05:00
James Bardin 7cba68326a always wait for a RunningOperation to return
If the user wishes to interrupt the running operation, only the first
interrupt was communicated to the operation by canceling the provided
context. A second interrupt would start the shutdown process, but not
communicate this to the running operation. This order of event could
cause partial writes of state.

What would happen is that once the command returns, the plugin system
would stop the provider processes. Once the provider processes dies, all
pending Eval operations would return return with an error, and quickly
cause the operation to complete. Since the backend code didn't know that
the process was shutting down imminently, it would continue by
attempting to write out the last known state. Under the right
conditions, the process would exit part way through the writing of the
state file.

Add Stop and Cancel CancelFuncs to the RunningOperation, to allow it to
easily differentiate between the two signals. The backend will then be
able to detect a shutdown and abort more gracefully.

In order to ensure that the backend is not in the process of writing the
state out, the command will always attempt to wait for the process to
complete after cancellation.

Laura Martin 6e1e614a56 Change -force to -auto-approve when destroying
Since an early version of Terraform, the `destroy` command has always
had the `-force` flag to allow an auto approval of the interactive
prompt. 0.11 introduced `-auto-approve` as default to `false` when using
the `apply` command.

The `-auto-approve` flag was introduced to reduce ambiguity of it's
function, but the `-force` flag was never updated for a destroy.

People often use wrappers when automating commands in Terraform, and the
inconsistency between `apply` and `destroy` means that additional logic
must be added to the wrappers to do similar functions. Both commands are
more or less able to run with similar syntax, and also heavily share
their code.

This commit updates the command in `destroy` to use the `-auto-approve` flag
making working with the Terraform CLI a more consistent experience.

We leave in `-force` in `destroy` for the time-being and flag it as
deprecated to ensure a safe switchover period.
