Martin Atkins ba0514106a return tfdiags.Diagnostics from validation methods
Validation is the best time to return detailed diagnostics
to the user since we're much more likely to have source
location information, etc than we are in later operations.

This change doesn't actually add any detail to the messages
yet, but it changes the interface so that we can gradually
introduce more detailed diagnostics over time.

While here there are some minor adjustments to some of the
messages to improve their consistency with terminology we
use elsewhere.

Merge #16543: Bring the "terraform" provider back into core 2017-11-03 12:08:31 -07:00
Martin Atkins d4ee58ce59 Re-integrate the "terraform" provider into the main binary
As part of the 0.10 core/provider split we moved this provider, along with
all the others, out into its own repository.

In retrospect, the "terraform" provider doesn't really make sense to be
separated since it's just a thin wrapper around some core code anyway,
and so re-integrating it into core avoids the confusion that results when
Terraform Core and the terraform provider have inconsistent versions of
the backend code and dependencies.

There is no good reason to use a different version of the backend code
in the provider than in core, so this new "internal provider" mechanism
is stricter than the old one: it's not possible to use an external build
of this provider at all, and version constraints for it are rejected as
a result.

This provider is also run in-process rather than in a child process, since
again it's just a very thin wrapper around code that's already running
in Terraform core anyway, and so the process barrier between the two does
not create enough advantage to warrant the additional complexity.

Martin Atkins 3da5fefdc1 command: Allow TF_DATA_DIR env var to override data directory
This allows the user to customize the location where Terraform stores
the files normally placed in the ".terraform" subdirectory, if e.g. the
current working directory is not writable.

Martin Atkins 400038eda4 command: "terraform apply" uses interactive confirmation by default
In the 0.10 release we added an opt-in mode where Terraform would prompt
interactively for confirmation during apply. We made this opt-in to give
those who wrap Terraform in automation some time to update their scripts
to explicitly opt out of this behavior where appropriate.

Here we switch the default so that a "terraform apply" with no arguments
will -- if it computes a non-empty diff -- display the diff and wait for
the user to type "yes" in similar vein to the "terraform destroy" command.

This makes the commonly-used "terraform apply" a safe workflow for
interactive use, so "terraform plan" is now mainly for use in automation
where a separate planning step is used. The apply command remains
non-interactive when given an explicit plan file.

The previous behavior -- though not recommended -- can be obtained by
explicitly setting the -auto-approve option on the apply command line,
and indeed that is how all of the tests are updated here so that they can
continue to run non-interactively.

Martin Atkins 5347f82f9a command: Include provider versions in "terraform version"
We encourage users to share the "terraform version" output as part of
filing an issue, but previously it only printed the core Terraform version
and this left provider maintainers with no information about which
_provider_ version an issue relates to.

Here we make a best effort to show versions for providers, though we will
omit some or all of them if either "terraform init" hasn't been run (and
so no providers were selected yet) or if there are other inconsistencies
that would cause Terraform to object on startup and require a re-run of
"terraform init".

Martin Atkins 34cecfa839 command/e2etest: fix incorrect "terraform version" test
Two different errors here caused this test to pass even though it was
incorrect: the wanted version string was incorrect, but the test for it
was also inverted, and so together this made the test pass even though
it was actually not testing the output at all.

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 5cd00a13ec command: use new diagnostics output for config errors
This uses the new diagnostics printer for config-related errors in the
main five commands that deal with config.

The immediate motivation for this is to allow HCL2-produced diagnostics
to be printed out in their full fidelity, though it also slightly changes
the presentation of other errors so that they are not presented in all
red text, which can be hard to read on some terminals.

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.

Martin Atkins fc20f419dd config and command: use errwrap to propagate config load errors
Previously we were using fmt.Sprintf and thus forcing the stringification
of the wrapped error.

Using errwrap allows us to unpack the original error at the top of the
stack, which is useful when the wrapped error is really a hcl.Diagnostics
containing potentially-multiple errors and possibly warnings.

Martin Atkins 73d1298572 command/e2etest: test the "running in automation" workflow
Since we now have a guide that recommends some specific ways to run
Terraform in automation, we can mimic those suggestions in an e2e test and
thus ensure they keep working.

Here we test the three different approaches suggested in the guide:
- init, plan, apply (main case)
- init, apply (e.g. for deploying to a QA/staging environment)
- init, plan (e.g. for verifying a pull request)

Martin Atkins e4f18c3f4d command: multi-argument autocomplete helper
The predictors built in to the "complete" package assume that the same
type of argument is repeated indefinitely, but most Terraform commands
don't work like that, so this helper allows us to define a sequence of
predictors that apply to each argument in turn.

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 fe4cfd03b5 command/format: restore "(forces new resource)" caption
In 3ea1592 the plan rendering was refactored to add an extra indirection
of producing a display-oriented plan object first and then rendering from
that object.

There was a logic error while adapting the existing plan rendering code
to use the new display-oriented object: the core InstanceDiff object sets
the "Destroy" flag (a boolean) for both DiffDestroy and DiffDestroyCreate,
and so this code previously checked r.Destroy to recognize the
"destroy-create" case. This was incorrectly adapted to a check for the
display action being DiffDestroy, when it should actually have been
DiffDestroyCreate.

The effect of this bug was to cause the "(forces new resource)"
annotations to not be displayed on attributes, though the resource-level
information still correctly reflected that a new resource was required.

This fix restores the attribute-level annotations.

Martin Atkins 83414beb8f command: various adjustments to the diff presentation
The previous diff presentation was rather "wordy", and not very friendly
to those who can't see color either because they have color-blindness or
because they don't have a color-supporting terminal.

This new presentation uses the actual symbols used in the plan output
and tries to be more concise. It also uses some framing characters to
try to separate the different stages of "terraform plan" to make it
easier to visually navigate.

The apply command also adopts this new plan presentation, in preparation
for "terraform apply" (with interactive plan confirmation) becoming the
primary, safe workflow in the next major release.

Finally, we standardize on the terminology "perform" and "actions" rather
than "execute" and "changes" to reflect the fact that reading is now an
action and that isn't actually a _change_.

Martin Atkins 3ea159297c command/format: improve consistency of plan results
Previously the rendered plan output was constructed directly from the
core plan and then annotated with counts derived from the count hook.
At various places we applied little adjustments to deal with the fact that
the user-facing diff model is not identical to the internal diff model,
including the special handling of data source reads and destroys. Since
this logic was just muddled into the rendering code, it behaved
inconsistently with the tally of adds, updates and deletes.

This change reworks the plan formatter so that it happens in two stages:
- First, we produce a specialized Plan object that is tailored for use
  in the UI. This applies all the relevant logic to transform the
  physical model into the user model.
- Second, we do a straightforward visual rendering of the display-oriented
  plan object.

For the moment this is slightly overkill since there's only one rendering
path, but it does give us the benefit of letting the counts be derived
from the same data as the full detailed diff, ensuring that they'll stay
consistent.

Later we may choose to have other UIs for plans, such as a
machine-readable output intended to drive a web UI. In that case, we'd
want the web UI to consume a serialization of the _display-oriented_ plan
so that it doesn't need to re-implement all of these UI special cases.

This introduces to core a new diff action type for "refresh". Currently
this is used _only_ in the UI layer, to represent data source reads.
Later it would be good to use this type for the core diff as well, to
improve consistency, but that is left for another day to keep this change
focused on the UI.

Martin Atkins c12d64f340 Use t.Helper() in our test helpers
Go 1.9 adds this new function which, when called, marks the caller as
being a "helper function". Helper function stack frames are then skipped
when trying to find a line of test code to blame for a test failure, so
that the code in the main test function appears in the test failure output
rather than a line within the helper function itself.

This covers many -- but probaly not all -- of our test helpers across
various packages.
