Martin Atkins 8b094f48f7 command: Update "terraform get" to use the new module installer
We missed this on the initial update pass because this was calling
directly into the module package API rather than going through the Meta
methods that we updated for the new config loader.

m.installModules here is the same method that "terraform init" is using
for this purpose, ensuring the two will behave the same way. This changes
the output a little compared to the old installer, but it still includes
the important information about where each module is coming from.

Martin Atkins 176a5abfd3 command: Restore single-file support in "terraform fmt"
This possibility was lost in the rewrite to use HCL2, but it's used by
a number of external utilities and text editor integrations, so we'll
restore it here.

Using the stdin/stdout mode is generally preferable for text editor use
since it allows formatting of the in-memory buffer rather than directly
the file on disk, but for editors that don't have support for that sort of
tooling it can be convenient to just launch a single command and directly
modify the on-disk file.

Martin Atkins b0a43cab84 command: "terraform fmt" must fail if file has invalid syntax
Since the HCL formatter only works with tokens, it can in principle be
called with any input and produce some output. However, when given invalid
syntax it will tend to produce nonsensical results that may drastically
change the input file and be hard for the user to undo.

Since there's no strong reason to try to format an invalid or incomplete
file, we'll instead try parsing first and fail if parsing does not
complete successfully.

Since we talk directly to the HCL API here this is only a _syntax_ check,
and so it can be applied to files that are invalid in other ways as far
as Terraform is concerned, such as using unsupported top-level block types,
resource types that don't exist, etc.

Martin Atkins 86c02d5c35 command: "terraform init" can partially initialize for 0.12upgrade
There are a few constructs from 0.11 and prior that cause 0.12 parsing to
fail altogether, which previously created a chicken/egg problem because
we need to install the providers in order to run "terraform 0.12upgrade"
and thus fix the problem.

This changes "terraform init" to use the new "early configuration" loader
for module and provider installation. This is built on the more permissive
parser in the terraform-config-inspect package, and so it allows us to
read out the top-level blocks from the configuration while accepting
legacy HCL syntax.

In the long run this will let us do version compatibility detection before
attempting a "real" config load, giving us better error messages for any
future syntax additions, but in the short term the key thing is that it
allows us to install the dependencies even if the configuration isn't
fully valid.

Because backend init still requires full configuration, this introduces a
new mode of terraform init where it detects heuristically if it seems like
we need to do a configuration upgrade and does a partial init if so,
before finally directing the user to run "terraform 0.12upgrade" before
running any other commands.

The heuristic here is based on two assumptions:
- If the "early" loader finds no errors but the normal loader does, the
  configuration is likely to be valid for Terraform 0.11 but not 0.12.
- If there's already a version constraint in the configuration that
  excludes Terraform versions prior to v0.12 then the configuration is
  probably _already_ upgraded and so it's just a normal syntax error,
  even if the early loader didn't detect it.

Once the upgrade process is removed in 0.13.0 (users will be required to
go stepwise 0.11 -> 0.12 -> 0.13 to upgrade after that), some of this can
be simplified to remove that special mode, but the idea of doing the
dependency version checks against the liberal parser will remain valuable
to increase our chances of reporting version-based incompatibilities
rather than syntax errors as we add new features in future.

Martin Atkins 2cf63d068f command: Always normalize config path before operations
Previously we were doing this rather inconsistently: some commands would
do it and others would not. By doing it here we ensure we always apply the
same normalization, regardless of which operation we're running.

This normalization is mostly for cosmetic purposes in error messages, but
it also ends up being used to populate path.module and path.root and so
it's important that we always produce consistent results here so that
we don't produce flappy changes as users work with different commands.

The fact that thus mutates a data structure as a side-effect is not ideal
but this is the best place to ensure it always gets applied without doing
any significant refactoring, since everything after this point happens in
the backend package where the normalizePath method is not available.

json output of terraform plan (#19687)
* command/show: adding functions to aid refactoring

The planfile -> statefile -> state logic path was getting hard to follow
with blurry human eyes. The getPlan... and getState... functions were
added to help streamline the logic flow. Continued refactoring may follow.

* command/show: use ctx.Config() instead of a config snapshot

As originally written, the jsonconfig marshaller was getting an error
when loading configs that included one or more modules. It's not clear
if that was an error in the function call or in the configloader itself,
  but as a simpler solution existed I did not dig too far.

* command/jsonplan: implement jsonplan.Marshal

Split the `config` portion into a discrete package to aid in naming
sanity (so we could have for example jsonconfig.Resource instead of
jsonplan.ConfigResource) and to enable marshaling the config on it's
own.

James Bardin 9667e06a03 decode backend hash as uint64
Older versions of terraform could save the backend hash number in a
value larger than an int.

While we could conditionally decode the state into an intermediary data
structure for upgrade, or detect the specific decode error and modify
the json, it seems simpler to just decode into the most flexible value
for now, which is a uint64.

The `tuncatedId` function had been introduced in #12261 and increased the

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()`.

And finally it renames some variables in the `[un]taint` code in order to try to standardize the var names of a few frequently used variables (e.g. statemgr.Full, states.State, states.SyncState).

Martin Atkins 884aa387b8 command: Use vendoring when building helper programs in tests
In a couple places in tests we execute a child "go build" to make a helper
program. Now that we're running in module mode, "go build" will normally
default to downloading and caching dependencies, which we don't want
because we're still using vendoring for the moment.

Therefore we need to instruct these child builds to use vendoring too,
avoiding the need to download all of the dependencies and ensuring that
we'll be building with the same dependencies that we'd use for a normal
build.

Martin Atkins 73c9521a04 command/e2etest: Temporarily disable tests that access network
Several of these tests rely on external services (e.g. Terraform Registry)
that have not yet been updated to support the needs of Terraform v0.12.0,
so for now we'll skip all of these tests and wait until those systems have
been updated.

This should be removed before Terraform v0.12.0 final to enable these
tests to be used as part of pre-release smoke testing.

Martin Atkins 53b5b95ef5 command: Fix TestRefresh_backup
The local filesystem state manager no longer creates backup files eagerly,
instead creating them only if on first write there is already a snapshot
present in the target file.

Therefore for this test to exercise the codepaths it intends to we must
create an initial state snapshot for it to overwrite, creating the backup
in the process.

There are several other tests for this behavior elsewhere, so this test
is primarily to verify that the refresh command is configuring the backend
appropriately to get the backups written in the desired location.

Martin Atkins 762a173c7f command: Fix TestRefresh_outPath
We now only create a backup state file if the given output file already
exists, which it does not in this test.

(The behavior of creating the backup files is already covered by other
tests, so no need for this one go out of its way to do it.)
2018-11-19 09:02:35 -08:00
Martin Atkins e2ba90fdfa command: Fix TestMetaBackend_planLocalMatch
We now don't create a local state backup until the first snapshot write,

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.
2018-11-19 09:02:35 -08:00
Martin Atkins 27abd9c6b8 command: Fix TestMetaBackend_localDoesNotDeleteLocal
The changes to how we handle setting the state path on the local backend
broke the heuristic we were using here for detecting migration from one
local backend to another with the same state path, which would by default
end up deleting the state altogether after migration.

We now use the StatePaths method to do this, which takes into account
both the default values and any settings that have been set.

Additionally this addresses a flaw in the old method which could
potentially have deleted all non-default workspace state files if the
"path" setting were changed without also changing the "workspace_dir"
setting. This new approach is conservative because it will preserve all
of the files if any one overlaps.
2018-11-19 09:02:35 -08:00
Martin Atkins be79bf0412 command: Fix TestPlan_outBackend
In an earlier change we fixed the "backendFromConfig" codepath to be
able to properly detect changes to the -backend-config arguments during
"terraform init", but this detection is too strict for the normal case
of running an operation in a previously-initialized directory.

Before any of the recent changes, the logic here was to selectively update
the hash to include -backend-config settings in the init case. Since
that late hash recalculation was confusing, here we take the alternative
path of using the hash only in the normal case and full value comparison
in the init case. Treating both of these cases separately makes things
marginally easier to follow here.
2018-11-19 09:02:35 -08:00
Martin Atkins b316e4ab56 command: Fix TestImport_remoteState
The import command was imposing the default state path at the CLI level,
rather than leaving that to be handled by the backend. As a result, the
output state was always forced to be terraform.tfstate, regardless of
the backend settings.
2018-11-19 09:02:35 -08:00
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 22c84c71a4 command: Use statemgr.Import and statemgr.Export for state push and pull
We previously hacked around the import/export functionality being missing
in the statemgr layer after refactoring, but now it's been reintroduced
to fix functionality elsewhere we should use the centralized Import and
Export functions to ensure consistent behavior.

In particular, this pushes the logic for checking lineage and serial
during push down into the state manager itself, which is better because
all other details about lineage and serial are managed within the state
managers.

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.

This test was incorrectly updated in a previous iteration, with it

Some other test is leaving behind a terraform.tfstate after it concludes,

This check doesn't fix that problem, but it at least makes the test fail
in a more helpful way to avoid time wasted trying to debug this test when
it's some other test that actually has the bug.

In prior refactoring we lost the required core version check from

Martin Atkins 9ba399bca8 command: Fix TestInit_getProvider

Martin Atkins f6d468ffd5 command: Fix TestInit_inputFalse
This test was using old-style state files as its input, differing only by
lineage. Since lineages are now managed within the state manager itself,
the test can't use that to distinguish the two files and so we put a
different output in each one instead.

This also introduces some TRACE logging to the migration codepaths.
There's some hard-to-follow control flow here and so this extra logging
helps to understand the reason for a particular outcome, and since this
codepath is visited only in "terraform init" anyway it doesn't hurt to
be a bit more verbose here.

Martin Atkins c0b7f58143 command: Fix detection of necessary backend migration
In the refactoring for new HCL this codepath stopped taking into account
changes to the CLI -backend-config options when deciding if a backend
migration is required.

This restores that behavior in a different way than it used to be: rather
than re-hashing the merged config and comparing the hashes, we instead
just compare directly the configuration values, which must be exactly
equal in order to skip migration.

This change is covered by the test TestInit_inputFalse, although as of
this commit it is still not passing due a downstream problem within the
migration code itself.

which is not realistic. Since we now cache configuration source code
inside command.Meta on load, it's important that we use a fresh
InitCommand instance here so it'll see the modified configuration file
we've left on disk.

Martin Atkins b5547f00f6 command: backendConfig must mutate its copy, not the original
Here we were going to the trouble of copying the body so we could mutate
it, but then ended up mutating the original anyway and then returning the
unmodified copy. Whoops!

This fix is verified by a number of "init" command tests that exercise the
-backend-config option, including TestInit_backendConfigFile and several
others whose names have the prefix TestInit_backendConfig .

Martin Atkins 8b603e4877 command: Name the Terraform Registry specifically in error message
When we originally wrote this message we struggled a bit for how to refer
to the releases server without writing an awkwardly-ungrammatical
sentence, and so "the official repository" became a placeholder name for
it.

Now that we'll be looking in Terraform Registry this gives us a nice
proper noun to use. This message will need to evolve more as our
integration with the registry gets more sophisticated, but for now this
works.

Martin Atkins 592850e22c command: Fix TestApply_plan_remoteState
Some over-zealous bulk updating of this test file caused this test to be
producing a remote state config cache file on disk when it doesn't
actually need one: the backend config comes from the plan file when
applying a saved plan.

Martin Atkins 1e45d30036 command: Fix TestPlan_outBackend
We missed fixing this up during the big updates for the new plan/state
models since the failures were being masked by testBackendState being
broken.

This is the same sort of update made to many other tests: add schema to
the mock provider, adjust for the new plan/state types, and make
allowances for the new built-in diffing behavior in core.
2018-11-08 08:57:11 -08:00
Martin Atkins c3d11b762b command: Fix testBackendState
The hashing function for cached backend configuration is different now, so
our hard-coded hash of the HTTP backend address wasn't working anymore.

Here we update the hash so that tests using this test backend will work
again. Rather than leaving it hard-coded, we'll instead compute it the
same way as "terraform init" would.

In practice only one test is actually using this function right now, so
we also update the test fixture for that test (TestPlan_outBackend) to
match the new expectations, though as of this commit it's still failing
with an unrelated error.
2018-11-08 08:57:11 -08:00
Martin Atkins e20346bf4f command: fix TestMeta_process
The mission of this process method used to include dealing with
auto-loaded tfvars files, but it doesn't do that anymore.

It does still deal with the -no-color option, but the test wasn't
exercising that part before.

Now the test here focuses on the -no-color behavior.

The process method still has a "vars" flag argument which is no longer
used. Since this is an unexported method we could potentially address this
but this commit is intentionally limited only to fixing the test.
2018-11-08 08:57:11 -08:00
Martin Atkins fcf3f643ce command: Fix TestPlan_shutdown
Comments here indicate that this was erroneously returning an error but
we accepted it anyway to get the tests passing again after other work.
The tests over in the "terraform" package agree that cancelling should be
a successful outcome rather than an error.

I think that cancelling _should_ actually be an error, since Terraform did
not complete the operation it set out to complete, but that's a change
we'd need to make cautiously since automation wrapper scripts may be
depending on the success-on-cancel behavior.

Therefore this just fixes the command package test to agree with the
Terraform package tests and adds some FIXME notes to capture the potential
that we might want to update this later.
2018-11-08 08:57:11 -08:00
Martin Atkins 0ea8aa6fe5 command: Fix TestWorkspace_createWithState
The State.Equal function is now more precise than this test needs. It's
only trying to distinguish between an empty state and a non-empty state,
so the string representation of state is good enough to get that done
while disregarding other subtle differences.

Martin Atkins 17b883f592 command/format: Include variable values in diagnostic messages
When HCL encounters an error during expression evaluation, it annotates
its diagnostics with information about the expression that was being
evaluated and the EvalContext it was evaluated in.

This gives us enough information to show helpful hints to the user about
the final values of any reference expressions that are present in the
expression, which is very useful extra context for expressions that get
evaluated multiple times, such as:
- Any expression in a block with "count" or "for_each" set
- The sub-expressions within a "for" expression

Martin Atkins 66f96cf842 command: Un-stub and reimplement "terraform state rm"
This was previously targeting the old state manager and state types, so it
needed some considerable rework to get it working again with the new state
types.

Since our new resource address syntax lacks the weird extra .deposed
special case we had before, we instead interpret addresses as
whole-instance addresses here and remove the deposed objects along with
the current one (if present), since this is more likely to match with
user expectations because we don't consider deposed objects to be
independently addressable in any other situation.

With that said, to be more explicit about what is going on we do now have
a -dry-run mode and maintain separate counts of current and deposed
instances so that we can expose that in the UI where relevant.

Martin Atkins 275a44f552 command: Reinstate object ids in the UIHook progress logs
We used to treat the "id" attribute of a resource as special and elevate
it into its own struct field "ID" in the state, but the new state format
and provider protocol treats it just as any other attribute.

However, it's still useful to show the value of a single identifying
attribute when there isn't room in the UI for showing all of the
attributes, and so here we take a new strategy of considering "id" along
with some other conventional names as special only in the UI layer.

This new heuristic approach can be adjusted over time as new provider
patterns emerge, but for now it covers some common conventions we've seen
in real providers.

With that said, since all existing providers made for Terraform versions
prior to v0.12 were forced to set "id", we won't see any use of other
attributes here until providers are updated to remove the placeholder
ids they were generating in cases where an id was not actually relevant
but was forced by the old protocol. At that point the UX should be
improved by showing a more relevant attribute instead.

We now also allow for the possibility of no id at all, since that is valid
for resources that exist only within the Terraform state, like the ones
from the "random" and "tls" providers.

Martin Atkins 43d5206d82 command: Stub the "terraform state mv" tests to remind to fix

it clear there is still work to do in the real implementation here.
2018-10-16 19:14:11 -07:00
Martin Atkins 1d64ce8ec0 command: Fix "terraform validate" tests

Martin Atkins 025540789c command: Restore the "terraform output" functionality
We previously stubbed most of this out because it hadn't yet been updated
to support the new state types, etc.

This restores all of the previous behavior as covered by the tests.

We intentionally remove one behavior that was not covered by the tests:
we used to allow retrieval of outputs from non-root modules using the
-module option, but since we no longer persist non-root outputs in the
state we can no longer support this without a full expression evaluation
walk, and that'd be overkill for this otherwise-simple command. Descendant
module outputs are not part of the public interface of a configuration
anyway, so accessing them from outside in this way is an anti-pattern.

(For debugging scenarios it is still possible to access these from
"terraform console", which _does_ do a full evaluation graph walk to
prepare its evaluation scope.)

Martin Atkins 34ebde0b95 command/format: be resilient to incomplete schema when formatting state
In all real cases the schemas should be populated here, but we don't want

This can also be tripped up by tests with incomplete mocks. It's
unfortunate that this can therefore mask some problems in tests, but tests
can protect against it by asserting on specific output text rather than
just assuming that a zero exit status is a pass.

Martin Atkins e8240087fe command: Populate backend configuration in plan files
In previous work we didn't quite connect these dots. The connection here
is sub-awesome since the existing interfaces here had some unfortunate
assumptions that we'd like to move away from (like the idea of a "nil
backend" implying the local backend) but we're accepting this for now to
avoid another big round of refactoring.

The main implication of this is that we will now always include a backend
configuration in the plan, though it might just be a placeholder config
for the local backend in the remaining cases where that's still implicitly
set. Later we will change this so that there is no implicit local backend
at all (terraform init is always required, _it_ will deal with setting
implicitly setting the local backend when appropriate), which will allow
us to rework this to be more straightforward and less "spooky".
2018-10-16 19:14:11 -07:00
Martin Atkins cbc548eb36 command: Do CLI init of backend loaded from plan
If we don't do this, we can't produce any output when applying a saved

function so that it won't panic if CLI init is skipped, although that
will no longer happen in the apply-from-file case due to the change
described in the previous paragraph.

Martin Atkins a43b7df282 core: Handle forced-create_before_destroy during the plan walk
Previously we used a single plan action "Replace" to represent both the
destroy-before-create and the create-before-destroy variants of replacing.
However, this forces the apply graph builder to jump through a lot of
hoops to figure out which nodes need it forced on and rebuild parts of
the graph to represent that.

If we instead decide between these two cases at plan time, the actual
determination of it is more straightforward because each resource is
represented by only one node in the plan graph, and then we can ensure
we put the right nodes in the graph during DiffTransformer and thus avoid
the logic for dealing with deposed instances being spread across various
different transformers and node types.

As a nice side-effect, this also allows us to show the difference between
destroy-then-create and create-then-destroy in the rendered diff in the
CLI, although this change doesn't fully implement that yet.

Martin Atkins b428746cfd command: UiHook to report when it gets incorrect values
For PreApply hook purposes we only actually use the Delete, Create, and
Update actions, because other actions are handled in different ways than
a direct call to ApplyResourceChange.

However, if there's a bug in core that causes it to pass a different
action, it's better for us to mark it as being explicitly unknown in the
UI rather than simply defaulting to "Modifying...", which can thus obscure
the problem and make for a confusing result.

Martin Atkins 30a46ed8ed command/format: Further refinement on the heuristic JSON-based diff
We'll now show an "update" symbol prior to the argument to this synthetic
jsonencode(...) call, for consistency with how we show nested values in
other cases and to attach a verb to any "# forces replacement".

We'll also show a special form in the case where the value seems to differ
only in whitespace, so users can understand what's going on in that
hopefully-rare situation, particularly if those whitespace-only changes
end up forcing us to replace a remote object.
2018-10-16 19:14:11 -07:00
Martin Atkins 783205948c command/format: JSON value formatting heuristic not for primitive values
Since our own syntax for primitive values is similar to that of JSON, and
since we permit automatic conversions from number and bool to string, we
must do this special JSON value diff formatting only if the value is a
JSON array or object to avoid confusing results.

Martin Atkins 4406b06ef8 command/format: Don't include commas after elements in map diffs

Martin Atkins ce157c7f23 command/format: show deep diffs for old/new JSON strings
Because so far we've not supported dynamically-typed complex data
structures, several providers have used strings containing JSON to stand
in for these.

In order to get a readable diff in those cases, we'll recognize situations
where old and new are both JSON and present a diff of the effective value
of the JSON, using a faux call to the jsonencode(...) function to indicate
when we've done so.

This is a bit of a "cute" heuristic, but is important at least for now
until we can migrate away from that practice of passing large JSON strings
to providers and use dynamically-typed attributes instead.

Martin Atkins 239a54ad6f command: initial structural diff rendering
This is a light adaptation of our earlier prototype of structural diff
rendering, as a starting point for what we'll actually ship. This is not
consistent with the latest mocks, so will need some additional work before
it is ready, but integrating this allows us to at least see the plan
contents while fixing up remaining issues elsewhere.

Martin Atkins a7342de274 core: Properly handle no-op changes in plan
Previously we just left these out of the plan altogether, but in the new
plan types we intentionally include change information for every resource
instance, even if no changes are actually planned, to allow alternative
plan file viewers to show what isn't changing as well as what is.
2018-10-16 19:14:11 -07:00
Martin Atkins 5731703de5 command/format: show planned changes in rendered plan
This codepath is going to be significantly changed before release to make
it support structural diff of the new data types, but this lets us lean on
the old renderer to produce partial output in the mean time while we
continue to work on getting things working end-to-end after the
considerable refactoring that's been going on.

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 479c6b2466 move "configschema" from "config" to "configs"
The "config" package is no longer used and will be removed as part
of the 0.12 release cleanup. Since configschema is part of the
"new world" of configuration modelling, it makes more sense for
it to live as a subdirectory of the newer "configs" package.

Martin Atkins adb88eaa16 configupgrade: Analysis of input configuration
In order to properly migrate the contents of resource, data, provider and
provisioner blocks we will need the provider's schema in order to
understand what is expected, so we can resolve some ambiguities inherent
in the legacy HCL AST.

This includes an initial prototype of migrating the content of resource
blocks just to verify that the information is being gathered correctly.
As with the rest of the upgrade_native.go file, this will be reorganized
significantly once the basic end-to-end flow is established and we can
see how to organize this code better.
2018-10-16 18:50:29 -07:00
Martin Atkins eac8779870 command: validate must set values for root variables
Since the intent of the validate command is to check config validity
regardless of context (input variables, state, etc), we use unknown values
of the requested type here, which will then allow us to complete type
checking against the specified types of the variables without assuming
any particular values.

Martin Atkins ffe5f7c4e6 command: 0.12upgrade command
This is the frontend to the work-in-progress codepath for upgrading the
source code for a module written for Terraform v0.11 or earlier to use
the new syntax and idiom of v0.12.

The underlying upgrade code is not yet complete as of this commit, and
so the command is not yet very useful. We will continue to iterate on
the upgrade code in subsequent commits.

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 fc7871c5ee command/import: default provider config in same module
Previously we were defaulting the provider configuration selection to a
provider in the root module inferred from the resource type name.

This is close, but not quite right: we need to _start_ with a provider
configuration in the same module as we're importing into, and then our
provider resolution steps during import graph construction will use that
as a starting point for a walk up the tree to find the nearest matching
configuration (which might eventually still be in the root, but not
necessarily).

Martin Atkins f085af4ba6 command: update "terraform console" for HCL2
This now uses the HCL2 parser and evaluator APIs and evaluates in terms
of a new-style *lang.Scope, rather than the old terraform.Interpolator
type that is no longer functional.

The Context.Eval method used here behaves differently than the
Context.Interpolater method used previously: it performs a graph walk
to populate transient values such as input variables, local values, and
output values, and produces its scope in terms of the result of that
graph walk. Because of this, it is a lot more robust than the prior method
when asked to resolve references other than those that are persisted
in the state.

Martin Atkins 9ca13d5c1d command/validate: make sure diagnostics is always present and an array
Previously an empty diagnostics would appear as "null" in the JSON output,
since that is how encoding/json serializes a nil slice. It's more
convenient for users of dynamic languages to keep the type consistent
in all cases, since they can then just iterate the list without needing a
special case for when it is null.
2018-10-16 18:46:46 -07:00
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 4ed06a9227 terraform: HCL2-flavored module dependency resolver
For the moment this is just a lightly-adapted copy of
ModuleTreeDependencies named ConfigTreeDependencies, with the goal that
the two can live concurrently for the moment while not all callers are yet
updated and then we can drop ModuleTreeDependencies and its helper
functions altogether in a later commit.

This can then be used to make "terraform init" and "terraform providers"
work properly with the HCL2-powered configuration loader.

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.
2018-10-16 18:44:26 -07:00
Martin Atkins 5782357c28 backend: Update interface and implementations for new config loader
The new config loader requires some steps to happen in a different
order, particularly in regard to knowing the schema in order to
decode the configuration.

Here we lean directly on the configschema package, rather than
on helper/schema.Backend as before, because it's generally
sufficient for our needs here and this prepares us for the
helper/schema package later moving out into its own repository
to seed a "plugin SDK".

Martin Atkins 618883596a command: remove "terraform push"
The remote API this talks to will be going away very soon, before our next

adding a .tfvars-formatted file to the uploaded archive.

Martin Atkins 9a004e3f9d command: "terraform validate" JSON support
In the long run we'd like to offer machine-readable output for more
commands, but for now we'll just start with a tactical feature in
"terraform validate" since this is useful for automated testing scenarios,
editor integrations, etc, and doesn't include any representations of types
that are expected to have breaking changes in the near future.
2018-10-16 18:20:32 -07:00
Martin Atkins bfd9392eb8 command: beginnings of new config loader in "terraform validate"
As part of some light reorganization of our commands, this new
implementation no longer does validation of variables and will thus avoid
the need to spin up a fully-valid context. Instead, its focus is on
validating the configuration itself, regardless of any variables, state,
etc.

This change anticipates us later adding a -validate-only flag to
"terraform plan" which will then take over the related use-case of
checking if a particular execution of Terraform is valid, _including_ the
state, variables, etc.

Although leaving variables out of validate feels pretty arbitrary today
while all of the variable sources are local anyway, we have plans to
allow per-workspace variables to be stored in the backend in future and
at that point it will no longer be possible to fully validate variables
without accessing the backend. The "terraform plan" command explicitly
requires access to the backend, while "terraform validate" is now
explicitly for local-only validation of a single module.

In a future commit this will be extended to do basic type checking of
the configuration based on provider schemas, etc.

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

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.
