addrs: replace "Type string" with "Type Provider" in ProviderConfig
* 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

James Bardin a5cb36b34c Allow moving instances to new resources
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.

James Bardin 32f7f58345 allow moving resource to new modules not in state
Create the missing modules in the state when moving resources to a
module that doesn't yet exist. This allows for refactoring of
configuration into new modules, without having to create dummy resources
in the module before the "state mv" operations.

Martin Atkins c39905e1a8 command: Fix various issues in the "terraform state ..." subcommands
In earlier refactoring we updated these commands to support the new
address and state types, but attempted to partially retain the old-style
"StateFilter" abstraction that originally lived in the Terraform package,
even though that was no longer being used for any other functionality.

Unfortunately the adaptation of the existing filtering to the new types
wasn't exact and so these commands ended up having a few bugs that were
not covered by the existing tests.

Since the old StateFilter behavior was the source of various misbehavior
anyway, here it's removed altogether and replaced with some simpler
functions in the state_meta.go file that are tailored to the use-cases of
these sub-commands.

As well as just generally behaving more consistently with the other
parts of Terraform that use the new resource address types, this commit
fixes the following bugs:

- A resource address of aws_instance.foo would previously match an
  resource of that type and name in any module, which disagreed with the
  expected interpretation elsewhere of meaning a single resource in the
  root module.

- The "terraform state mv" command was not supporting moves from a single
  resource address to an indexed address and vice-versa, because the old
  logic didn't need to make that distinction while they are two separate
  address types in the new logic. Now we allow resources that do not have
  count/for_each to be treated as if they are instances for the purposes
  of this command, which is a better match for likely user intent and for
  the old behavior.

Finally, we also clean up a little some of the usage output from these
commands, which hasn't been updated for some time and so had both some
stale information and some inaccurate terminology.

Martin Atkins 43d5206d82 command: Stub the "terraform state mv" tests to remind to fix
This command isn't yet updated for the new state types, but since we were
not returning a non-successful error status here the tests were just
failing in a weird way instead. Now we'll fail with a message that makes
it clear there is still work to do in the real implementation here.

Martin Atkins a3403f2766 terraform: Ugly huge change to weave in new State and Plan types
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.

The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.

The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.

Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.

James Bardin 51547ad2ba add tests for state commands through a backend 2017-07-27 18:06:47 -04:00
James Bardin 33ba6774e0 Make the state commands use the real command.Meta
In order to use a backend for the state commands, we need an initialized
meta. Use a single Meta instance rather than temporary ones to make sure
the backends are initialized properly.

James Bardin 6e7baaaeff don't load the backend when -state is provided
When using a `state` command, if the `-state` flag is provided we do not
want to modify the Backend state. In this case we should always create a
local state instance.

The backup flag was also being ignored, and some tests were relying on
that, which have been fixed.

James Bardin 5f939b42fe test that `state mv -state` doesn't use Backend
If we provide a -state flag to a state command, we do not want terraform
to modify the backend state. This test fails since the state specified
in the backend doesn't exist

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 43c7bd648c fix sorting of module resources during state mv
Module resource were being sorted lexically by name by the state filter.
If there are 10 or more resources, the order won't match the index
order, and resources will have different indexes in their new location.

Sort the FilterResults by index numerically when the names match.

Clean up the module String output for visual inspection by sorting
Resource name parts numerically when they are an integer value.

command/state: mv and rm -backup works
Fixes #12154

The "-backup" flag before for "state *" CLI had some REALLY bizarre behavior:
it would change the _destination_ state and actually not create any
additional backup at all (the original state was unchanged and the
normal timestamped backup still are written). Really weird.

This PR makes the -backup flag work as you'd expect with one caveat:
we'll _still_ create the timestamped backup file. The timestamped backup
file helps make sure that you always get a backup history when using
these commands. We don't want to make it easy for you to overwrite a
state with the `-backup` flag.
