Sander van Harmelen ef9054562e commands: make sure the correct flagset is used
A lot of commands used `c.Meta.flagSet()` to create the initial flagset for the command, while quite a few of them didn’t actually use or support the flags that are then added.

So I updated a few commands to use `flag.NewFlagSet()` instead to only add the flags that are actually needed/supported.

Additionally this prevents a few commands from using locking while they actually don’t need locking (as locking is enabled as a default in `c.Meta.flagSet()`.

Martin Atkins e2ba90fdfa command: Fix TestMetaBackend_planLocalMatch
We now don't create a local state backup until the first snapshot write,
so we don't expect there to be a backup file until the end of the test.
(There is already a check at the end there, unmodified by this change.)

Martin Atkins 48601d261d states/statemgr: In Filesystem, back up output file, not input file
The filesystem backend has the option of using a different file for its
initial read.

Previously we were incorrectly writing the contents of that file out into
the backup file, rather than the prior contents of the output file. Now
we will always read the output file in RefreshState in order to decide
what we will back up but then we will optionally additionally read the
input file and prefer its content as the "current" state snapshot.

This is verified by command.TestMetaBackend_planLocalStatePath and
TestMetaBackend_configureNew, which are both now passing.

Martin Atkins 2b9f92be31 command: Partially fix TestMetaBackend_planLocalStatePath
This test is testing some strange implementation details of the old
local backend which do not hold with the new filesystem state manager.
Specifically, it was expecting state to be read from the stateOutPath
rather than the statePath, which makes no sense here because the backend
is configured to read from the default terraform.tfstate file (which does
not exist.)

There is another problem with this test which will be addressed in a
subsequent commit.

Martin Atkins aecb66d3db command: Fix TestMetaBackend_configuredChangeCopy_multiToNoDefaultWithoutDefault
As part of integrating the new "remote" backend we relaxed the requirement
that a "default" workspace must exist in all backends and now skip
migrating empty workspace states to avoid creating unnecessary "default"
workspaces when switching between backends that require it and backends
that don't, such as when switching from the local backend (which always
has a "default" workspace) to Terraform Enterprise.
2018-11-19 09:02:35 -08:00
Martin Atkins ec27526cc3 command: Fix TestMetaBackend_configuredChangeCopy_multiToMulti
This was failing because we now handle the settings for the local backend
a little differently as a result of decoding it with the HCL2 machinery.

Specifically, the backend.State* fields are now assumed to be what is
given in configuration, and any CLI overrides are maintained separately
in OverrideState* fields so that they can be imposed "just in time" in
StatePaths.

This is particularly important because OverrideStatePath (when set) is
used regardless of workspace name, while StatePath is a suitable value
only for the "default" workspace, with others needing to be constructed
from StateWorkspaceDir instead.

Martin Atkins f39a5d0962 command: Fix various TestMetaBackend-prefix tests
Our new state model has a different implementation of "empty" that doesn't
consider lineage/serial, so we need to have some actual content in these
state fixtures to avoid them being skipped during state migrations.
2018-11-19 09:02:35 -08:00
Martin Atkins aacbe1d14b command: Fix TestMetaBackend_configureNewWithState
This test was initially failing because its fixture had a state which our
new state models consider to be "empty", and thus it was not migrated.

After fixing that (by adding an output to the fixture), this revealed a
bug that the lineage was not being persisted through the migration. This
is fixed by using the statemgr.Migrate method instead of writing via the
normal Writer interface, which allows two cooperating state managers to
properly transfer the lineage and serial along with the state snapshot.
2018-11-19 09:02:35 -08:00
Martin Atkins 2293391241 command: Fix TestMetaBackend_emptyWithExplicitState
This test was incorrectly updated in a previous iteration, with it
creating a modified state to write but then not actually writing it,
writing an empty test state instead.

This made the test fail because a backup state file is created only if
the new state snapshot is different to the old when written.

Sander van Harmelen 52a1b22f7a Implement the remote enhanced backend
This is a refactored version of the `remote` backend that was initially added to Terraform v0.11.8 which should now be compatible with v0.12.0.
2018-11-06 16:29:46 +01:00
Martin Atkins 541952bb8f Revert some work that happened since v0.12-dev branched
This work was done against APIs that were already changed in the branch
before work began, and so it doesn't apply to the v0.12 development work.

To allow v0.12 to merge down to master, we'll revert this work out for now
and then re-introduce equivalent functionality in later commits that works
against the new APIs.

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 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 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.

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

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.
2017-02-09 15:47:27 -05:00
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 8f7f1917f2 Remove state file data when writing a nil state
The old behavior in this situation was to simply delete the file. Since

James Bardin eb59b5925e Fix some tests, and make rest fail with good errs
