Martin Atkins 0742e756e5 tfdiags: Sort order for diagnostics
Because we gather together diagnostics from many different parts of the
codebase, the list often ends up being in a non-ideal order. Here we
define a partial ordering for diagnostics that should hopefully make them
easier to scan when many are present, by grouping together diagnostics
that are of the same severity and belong to the same file.

We use sort.Stable here because we have a partial order and so we need
to make sure that diagnostics that do not have a relative ordering will
remain in their original order.

This sorting is applied just in time before rendering the diagnostics
in command.Meta.showDiagnostics.

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 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.

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 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!

James Bardin e63a3474d5 kill the flag error writer after 2 seconds
There's no point in trying to track these, they're lost after each test.
Kill them after a short delay so we don't have goroutines from every single
command test to wade through if we have a stack dump.

James Bardin 885e4cde81 don't loop indefinitely in confirm method
Only check for input twice in the meta.confirm method. This prevents an
errant newline from aborting the run while allowing Terraform to exit if
there is no input available. We don't just check for a tty, since we
still rely on being able to pipe input in for testing.

Remove the redundant confirmation loops in the migration code, and only
use the confirm method.

James Bardin 2941ed464c replace the testShutdownHook with a check for Stop
Now that the local backend can be cancelled during plan and refresh, we
don't really need the testShutdownHook. Simplify the tests by just
checking for Stop being called on the provider.

James Bardin 3aaa1e9d04 make plans cancellable

Martin Atkins 865e61b4ea main+command: provide service disco and creds to commands
The command package is the main place we need access to these, so that
we can use them during init (to install packages, for example) and so that
we can use them to configure remote backends.

For the moment we're just providing an empty credentials object, which
will start to include both statically-configured and
helper-program-provided credentials sources in subsequent commits.

Martin Atkins ea81e75a4e command: utility for rendering tfdiag diagnostics
This new method showDiagnostics takes any value that would be accepted by
tfdiags.Append and renders it to the UI.

This is intended to encourage consistent handling of the different kinds
of errors and diagnostics that can be produced, and allow richer error
objects like the HCL2 diagnostics to be easily unwrapped and shown in
their full-fidelity.

Jack Bruno 3f2136d7ee cli: terraform import -ignore-missing-config

Martin Atkins 0fe43c8977 cli: allow disabling "next steps" message in terraform plan
In #15884 we adjusted the plan output to give an explicit command to run
to apply a plan, whereas before this command was just alluded to in the
prose.

Since releasing that, we've got good feedback that it's confusing to
include such instructions when Terraform is running in a workflow
automation tool, because such tools usually abstract away exactly what
commands are run and require users to take different actions to
proceed through the workflow.

To accommodate such environments while retaining helpful messages for
normal CLI usage, here we introduce a new environment variable
TF_IN_AUTOMATION which, when set to a non-empty value, is a hint to
Terraform that it isn't being run in an interactive command shell and
it should thus tone down the "next steps" messaging.

The documentation for this setting is included as part of the "...in
automation" guide since it's not generally useful in other cases. We also
intentionally disclaim comprehensive support for this since we want to
avoid creating an extreme number of "if running in automation..."
codepaths that would increase the testing matrix and hurt maintainability.

The focus is specifically on the output of the three commands we give in
the automation guide, which at present means the following two situations:

* "terraform init" does not include the final paragraphs that suggest
  running "terraform plan" and tell you in what situations you might need
  to re-run "terraform init".
* "terraform plan" does not include the final paragraphs that either
  warn about not specifying "-out=..." or instruct to run
  "terraform apply" with the generated plan file.

Martin Atkins 3df164502a command: don't prompt for state migration if TF_INPUT is set
The "confirm" method was directly checking the meta struct's input field,
but that only represents the -input command line flag, and doesn't
respect the TF_INPUT environment variable.

By calling the Input method instead, we check both.

This fixes #15338.

James Bardin 55bf19e548 always write to dataDir in the current directory
Now that init can take a directory for configuration, the old behavior
of writing the .terraform data directory into the target path no longer
makes sense. Don't change the dataDir field during init, and write to
the default location.

Clean up all references to Meta.dataDir, and only use the getter method
in case we chose to dynamically override this at some point.

Martin Atkins 418a8a8bc9 command + backend: rename various API objects to "Workspace" terminology
We're shifting terminology from "environment" to "workspace". This takes
care of some of the main internal API surface that was using the old
terminology, though is not intended to be entirely comprehensive and is
mainly just to minimize the amount of confusion for maintainers as we
continue moving towards eliminating the old terminology.

Martin Atkins 31d556894f command: shallow UI-focused rename of "environment" to "workspace"
Feedback after 0.9 was that the term "environment" was confusing due to
it colliding with several other concepts, such as OS environment
variables, a non-aligned Terraform Enterprise concept, and differing ideas
of "environment" within various organizations.

This new term "workspace" is intended to ease some of that confusion. This
term is not used anywhere else in Terraform today, and we expect it to not
be used in a manner that would be confusing within user organizations.

This begins a deprecation cycle for the "terraform env" family of commands,
instead moving to an equivalent set of "terraform workspace" commands.

There are some remaining references to the old "environment" concept in
the code, which will be cleaned up in a separate change. This change is
instead focused on text visible in the UI and wording within code comments
for the benefit of human maintainers of the code.

Martin Atkins 4571a16b15 command: remove Meta.forceProviderSHA256s
This was added with the idea of using it to override the SHA256 hashes
to match those hypothetically stored in a plan, but we already have a
mechanism elsewhere for populating context fields from plan fields, so
this is not actually necessary.
2017-06-09 14:03:59 -07:00
Martin Atkins 6ba6508ec9 command: pass the locked plugin hashes into ContextOpts
By reading our lock file and passing this into the context, we ensure that
only the plugins referenced in the lock file can be used. As of this
commit there is no way to create that lock file, but that will follow soon
as part of "terraform init".

We also provide a way to force a particular set of SHA256s. The main use
for this is to allow us to persist a set of plugins in the plan and
check the same plugins are used during apply, but it may also be useful
for automated tests.
2017-06-09 14:03:59 -07:00
Martin Atkins 7ca592ac06 core: use ResourceProviderResolver to resolve providers
Previously the set of providers was fixed early on in the command package
processing. In order to be version-aware we need to defer this work until
later, so this interface exists so we can hold on to the possibly-many
versions of plugins we have available and then later, once we've finished
determining the provider dependencies, select the appropriate version of
each provider to produce the final set of providers to use.

This commit establishes the use of this new mechanism, and thus populates
the provider factory map with only the providers that result from the
dependency resolution process.

This disables support for internal provider plugins, though the
mechanisms for building and launching these are still here vestigially,
to be cleaned up in a subsequent commit.

This also adds a new awkward quirk to the "terraform import" workflow
where one can't import a resource from a provider that isn't already
mentioned (implicitly or explicitly) in config. We will do some UX work
in subsequent commits to make this behavior better.

This breaks many tests due to the change in interface, but to keep this
particular diff reasonably easy to read the test fixes are split into
a separate commit.

Martin Atkins 8364383c35 Push plugin discovery down into command package
Previously we did plugin discovery in the main package, but as we move
towards versioned plugins we need more information available in order to
resolve plugins, so we move this responsibility into the command package
itself.

For the moment this is just preserving the existing behavior as long as
there are only internal and unversioned plugins present. This is the
final state for provisioners in 0.10, since we don't want to support
versioned provisioners yet. For providers this is just a checkpoint along
the way, since further work is required to apply version constraints from
configuration and support additional plugin search directories.

The automatic plugin discovery behavior is not desirable for tests because
we want to mock the plugins there, so we add a new backdoor for the tests
to use to skip the plugin discovery and just provide their own mock
implementations. Most of this diff is thus noisy rework of the tests to
use this new mechanism.

James Bardin 797a1b339d DebugInfo and DebugGraph
Implement debugInfo and the DebugGraph

DebugInfo will be a global variable through which graph debug
information can we written to a compressed archive. The DebugInfo
methods are all safe for concurrent use, and noop with a nil receiver.
The API outside of the terraform package will be to call SetDebugInfo
to create the archive, and CloseDebugInfo() to properly close the file.
Each write to the archive will be flushed and sync'ed individually, so
in the event of a crash or a missing call to Close, the archive can
still be recovered.

The DebugGraph is a representation of a terraform Graph to be written to
the debug archive, currently in dot format. The DebugGraph also contains
an internal buffer with Printf and Write methods to add to this buffer.
The buffer will be written to an accompanying file in the debug archive
along with the graph.

This also adds a GraphNodeDebugger interface. Any node implementing
`NodeDebug() string` can output information to annotate the debug graph
node, and add the data to the log. This interface may change or be
removed to provide richer options for debugging graph nodes.

The new graph builders all delegate the build to the BasicGraphBuilder.
Having a Name field lets us differentiate the actual builder
implementation in the debug graphs.

command/meta: always ask for unset variable input
Fixes #7975

This changes the InputMode for the CLI to always be:

    InputModeProvider | InputModeVar | InputModeVarUnset

Which means:

  * Ask for provider variables
  * Ask for user variables _that are not already set_

The change is the latter point. Before, we'd only ask for variables if
zero were given. This forces the user to either have no variables set
via the CLI, env vars, tfvars or ALL variables, but no in between. As
reported in #7975, this isn't expected behavior.

The new change makes is so that unset variables are always asked for.
Users can retain the previous behavior by setting `-input=false`. This
would ensure that variables set by external sources cover all cases.

command/apply: apply from plan respects -backup and -state-out
Fixes #5409

I didn't expect this to be such a rabbit hole!

Based on git history, it appears that for "historical reasons"(tm),
setting up the various `state.State` structures for a plan were
_completely different logic_ than a normal `terraform apply`. This meant
that it was skipping things like disabling backups with `-backup="-"`.

This PR unifies loading from a plan to the normal state setup mechanism.
A few tests that were failing prior to this PR were added, no existing
tests were changed.

helper/experiment: a helper for setting, making experiments
This creates a standard package and interface for defining, querying,
setting experiments (`-X` flags).

I expect we'll want to continue to introduce various features behind
experimental flags. I want to make doing this as easy as possible and I
want to make _removing_ experiments as easy as possible as well.

The goal with this packge has been to rely on the compiler enforcing our
experiment references as much as possible. This means that every
experiment is a global variable that must be referenced directly, so
when it is removed you'll get compiler errors where the experiment is
referenced.

This also unifies and makes it easy to grab CLI flags to enable/disable
experiments as well as env vars! This way defining an experiment is just
a couple lines of code (documented on the package).

James Nugent 681d94ae20 core: Allow lists and maps as variable overrides
Terraform 0.7 introduces lists and maps as first-class values for
variables, in addition to string values which were previously available.
However, there was previously no way to override the default value of a
list or map, and the functionality for overriding specific map keys was
broken.

Using the environment variable method for setting variable values, there
was previously no way to give a variable a value of a list or map. These
now support HCL for individual values - specifying:

    TF_VAR_test='["Hello", "World"]'

will set the variable `test` to a two-element list containing "Hello"
and "World". Specifying

    TF_VAR_test_map='{"Hello = "World", "Foo" = "bar"}'

will set the variable `test_map` to a two-element map with keys "Hello"
and "Foo", and values "World" and "bar" respectively.

The same logic is applied to `-var` flags, and the file parsed by
`-var-files` ("autoVariables").

Note that care must be taken to not run into shell expansion for `-var-`
flags and environment variables.

We also merge map keys where appropriate. The override syntax has
changed (to be noted in CHANGELOG as a breaking change), so several
tests needed their syntax updating from the old `amis.us-east-1 =
"newValue"` style to `amis = "{ "us-east-1" = "newValue"}"` style as
defined in TF-002.

In order to continue supporting the `-var "foo=bar"` type of variable
flag (which is not valid HCL), a special case error is checked after HCL
parsing fails, and the old code path runs instead.

James Bardin 6b5ee73e86 Use -state-out option when applying from a plan
When working from an existing plan, we weren't setting the PathOut field
for a LocalState. This required adding an outPath argument to the
StateFromPlan function to avoid having to introspect the returned
state.State interface to find the appropriate field.

To test we run a plan first and provide the new plan to apply with
`-state-out` set.

Mitchell Hashimoto 35c87836b4 core: Add terraform_version to state
This adds a field terraform_version to the state that represents the
Terraform version that wrote that state. If Terraform encounters a state
written by a future version, it will error. You must use at least the
version that wrote that state.

Internally we have fields to override this behavior (StateFutureAllowed),
but I chose not to expose them as CLI flags, since the user can just
modify the state directly. This is tricky, but should be tricky to
represent the horrible disaster that can happen by enabling it.

We didn't have to bump the state format version since the absense of the
field means it was written by version "0.0.0" which will always be
older. In effect though this change will always apply to version 2 of
the state since it appears in 0.7 which bumped the version for other
purposes.

Mitchell Hashimoto d1b46e99bd Add `terraform state list` command
This introduces the terraform state list command to list the resources
within a state. This is the first of many state management commands to
come into 0.7.

This is the first command of many to come that is considered a
"plumbing" command within Terraform (see "plumbing vs porcelain":
http://git.661346.n2.nabble.com/what-are-plumbing-and-porcelain-td2190639.html).
As such, this PR also introduces a bunch of groundwork to support
plumbing commands.

The main changes:

- Main command output is changed to split "common" and "uncommon"
  commands.

- mitchellh/cli is updated to support nested subcommands, since
  terraform state list is a nested subcommand.

- terraform.StateFilter is introduced as a way in core to filter/search
  the state files. This is very basic currently but I expect to make it
  more advanced as time goes on.

- terraform state list command is introduced to list resources in a
  state. This can take a series of arguments to filter this down.

Known issues, or things that aren't done in this PR on purpose:

- Unit tests for terraform state list are on the way. Unit tests for the
  core changes are all there.

Paul Hinze e67fc0fe9b command: Change module-depth default to -1
This means that terraform commands like `plan`, `apply`, `show`, and
`graph` will expand all modules by default.

While modules-as-black-boxes is still very true in the conceptual design
of modules, feedback on this behavior has consistently suggested that
users would prefer to see more verbose output by default.

The `-module-depth` flag and env var are retained to allow output to be
optionally limited / summarized by these commands.

Paul Hinze 97acccd3ed core: targeted operations
Add `-target=resource` flag to core operations, allowing users to
target specific resources in their infrastructure. When `-target` is
used, the operation will only apply to that resource and its
dependencies.

The calculated dependencies are different depending on whether we're
running a normal operation or a `terraform destroy`.

Generally, "dependencies" refers to ancestors: resources falling
_before_ the target in the graph, because their changes are required to
accurately act on the target.

For destroys, "dependencies" are descendents: those resources which fall
_after_ the target. These resources depend on our target, which is going
to be destroyed, so they should also be destroyed.
