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.

Martin Atkins a270a18a4d command: Update tests for changes in "terraform" package
This is not exhaustive, but it gets the tests in this package compiling
again and gets most of them working.

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.

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.

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.

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.

James Bardin 0e0f0b64b9 add init -reconfigure test
Check that we can reconfigure a backend ignoring the saved config, and
without effecting the saved backend.

James Bardin fb4a365d12 noop migrate copy, add -lock and -input
A couple commits got rebased together here, and it's easier to enumerate
them in a single commit.

Skip copying of states during migration if they are the same state. This
can happen when trying to reconfigure a backend's options, or if the
state was manually transferred. This can fail unexpectedly with locking
enabled.

Honor the `-input` flag for all confirmations (the new test hit some
more). Also unify where we reference the Meta.forceInitCopy and transfer
the value to the existing backendMigrateOpts.force field.

James Bardin 8050eda52d don't delete local state on a local backend
Don't erase local state during backend migration if the new and old
paths are the same. Skipping the confirmation and copy are handled in
another patch, but the local state was always erased by default, even
when it was our new state.

James Bardin 54e536cfe0 add `-force-copy` option to init command
The `-force-copy` option will suppress confirmation for copying state
data.

Modify some tests to use the option, making sure to leave coverage of
the Input code path.

command: remove legacy remote state on migration
Fixes #12871

We were forgetting to remove the legacy remote state from the actual
state value when migrating. This only causes an issue when saving a plan
since the plan contains the state itself and causes an error where both
a backend + legacy state exist.

If saved plans aren't used this causes no noticable issue.

Due to buggy upgrades already existing in the wild, I also added code to
clear the remote section if it exists in a standard unchanged backend

command: apply needs to look at the right field for backend state
Plans were properly encoding backend configuration but the apply was
reading it from the wrong field. :( This meant that every apply from a
plan was applying it locally with backends.

This needs to get released ASAP.

James Bardin ea095eda87 change to default state after backend migration
When migrating from a multi-state backend to a single-state backend, we
have to ensure that our locally configured environment is changed back
to "default", or we won't be able to access the new backend.

backend/local: don't RefreshState on State API 2017-02-22 13:01:16 -08:00
James Bardin 0c1b138719 Add state locking during backend init
During backend initialization, especially during a migration, there is a
chance that an existing state could be overwritten.

Attempt to get a locks when writing the new state. It would be nice to
always have a lock when reading the states, but the recursive structure
of the Meta.Backend config functions makes that quite complex.

James Bardin 94f2f4d6ae Create state files first for backup tests
Previously when runnign a plan with no exitsing state, the plan would be
written out and then backed up on the next WriteState by another
BackupState instance. Since we now maintain a single State instance
thoughout an operation, the backup happens before any state exists so no
backup file is created.

This is OK, as the backup state the tests were checking for is from the
plan file, which already exists separate from the state.

James Bardin 39ca4fa2f8 Ensure that backend tests check for data in state
Test should not simply check for the existence of a file for state, but
make sure that file also contains data.

James Bardin 8f7f1917f2 Remove state file data when writing a nil state
The old behavior in this situation was to simply delete the file. Since
we now have a lock on this file we don't want to close or delete it, so
instead truncate the file at offset 0.

Fix a number of related tests
2017-01-30 17:16:57 -05:00
James Bardin eb59b5925e Fix some tests, and make rest fail with good errs
Having the state files always created for locking breaks a lot of tests.
Most can be fixed by simple checking for state within a file, but a few
still might be writing state when they shouldn't.
