Alisdair McDiarmid c98f352dc8 terraform: Fix required version constraint diags
If a module has multiple terraform.required_version constraints, any
failures would point at the last constraint in the error diagnostics. If
an earlier constraint was the actual problem, this leads to confusing
errors like this:

    Error: Unsupported Terraform Core version

      on main.tf line 6, in terraform:
       6:   required_version = ">= 0.13.0"

    This configuration does not support Terraform version 0.13.0.

The error was due to storing the declaration range of the constraint as
a pointer to the contents of a loop variable, which was later
overwritten in later iterations of the loop.  Instead we now use HCL's
handy Ptr() method to create a direct pointer to the range struct.

Alisdair McDiarmid d8e9964363 terraform: Eval module call arguments for import
Include the import walk in the list of operations for which we create an
EvalModuleCallArgument node. This causes module call arguments to be
evaluated even if the module variables have defaults, ensuring that
invalid default values (such as the common "{}" for variables thought of
as maps) do not cause failures specific to import.

This fixes a bug where a child module evaluates an input variable in its
locals block, assuming that it is a nested object structure. The bug
report includes a default value of "{}", which is overridden by a root
variable value. Without the eval node added in this commit, the default
value is used and the local evaluation errors.

Alisdair McDiarmid 96d2265ddb command: Add test for invalid selected workspace

Alisdair McDiarmid 8252920e9a command: Allow workspace delete with invalid name
We are validating the workspace name for all workspace commands. Due to

to accidentally create a workspace with an invalid name.

This commit removes the valid workspace name check for workspace delete
to allow users to clean up any invalid workspaces.

Alisdair McDiarmid b239570abb command: Always validate workspace name
The workspace name can be overridden by setting a TF_WORKSPACE
environment variable. If this is done, we should still validate the
resulting workspace name; otherwise, we could end up with an invalid and
unselectable workspace.

This change updates the Meta.Workspace function to return an error, and
handles that error wherever necessary.

Alisdair McDiarmid 17e1c9dd05 command: Fix state mv for only resource in module
When moving a resource block with multiple instances to a new address
within the same module, we need to ensure that the target module is
present as late as possible. Otherwise, deleting the resource from the
original address triggers pruning, and the module is removed just before
we try to add the resource to it, which causes a crash.

Includes regression test which panics without this code change.

state: remove deprecated state package (#25490)
Most of the state package has been deprecated by the states package.
This PR replaces all the references to the old state package that
can be done simply - the low-hanging fruit.

* states: move state.Locker to statemgr

The state.Locker interface was a wrapper around a statemgr.Full, so
moving this was relatively straightforward.

* command: remove unnecessary use of state package for writing local terraform state files

* move state.LocalState into terraform package

state.LocalState is responsible for managing terraform.States, so it
made sense (to me) to move it into the terraform package.

* slight change of heart: move state.LocalState into clistate instead of
terraform

* backend/local: push responsibility for unlocking state into individual operations
* unlock the state if Context() has an error, exactly as backend/remote does today
* terraform console and terraform import will exit before unlocking state in case of error in Context()
* responsibility for unlocking state in the local backend is pushed down the stack, out of backend.go and into each individual state operation
* add tests confirming that state is not locked after apply and plan

* backend/local: add checks that the state is unlocked after operations

This adds tests to plan, apply and refresh which validate that the state
is unlocked after all operations, regardless of exit status. I've also
added specific tests that force Context() to fail during each operation
to verify that locking behavior specifically.

command/show: fix bug displaying provider config in json output of tf plan (#25577)
A lingering FIXME caused missing configuration from provider config
blocks in the json output of terraform plan. This fixes the regression
and adds a test. For the sake of testing, I added an optional attribute
to the show test provider, which resulted in the providers schema test
getting an update - not a bad addition, but we can always add a
test-specific provider schema as needed.

Martin Atkins 7909dd318d command/init: Specialized error message for host that isn't registry
If the user specifies a host that isn't a provider registry in a provider
source address then we'll print out some specialized error messages for
different variants of that situation.

In particular, this includes a special case for when the error is on the
hostname "github.com", in anticipation of folks incorrectly attempting to
use GitHub repository URLs (or Go-style module paths that happen to be
on GitHub) to specify providers, so we can give a more specific hint about
that.

This is just a different presentation of an existing error case that we
are already covering in the installer tests, so there are no new tests
here. We could in principle have a test covering the exact text of these
error messages, but we don't have much precedent for command package tests
covering that level of cosmetic detail.

Martin Atkins 80ab867e57 command/init: Remove special 0.12upgrade heuristic
For Terraform v0.12 we introduced a special loading mode where we would
use the 0.11-syntax-compatible "earlyconfig" package as a heuristic to
identify situations where it was likely that the user was trying to use
0.11-only syntax that the upgrade tool might help with.

However, as the language has moved on that is no longer a suitable
heuristic in Terraform 0.13 and later: other new additions to the
language can cause the main loader to disagree with earlyconfig, which
would lead us to give poor advice about how to respond.

Instead, we'll now return the same generic "there are errors" message in
all syntax error cases. We have an extra message for errors in this
case (as compared to other commands) because "terraform init" is usually
the first command a new user interacts with and so this message gives some
extra explanation about what "terraform init" will do with the
configuration once it's valid.

This also includes a reset control character in the output of the message
as part of our ongoing mission to stop Terraform printing out whole
paragraphs of colored text, which can often be hard to read for various
reasons.

backend/local: release lock if there is an error in Context() (#25427)
* command/console: return in case of errors before trying to unlock remote
state

The remote backend `Context` would exit without an active lock if there
was an error, while the local backend `Context` exited *with* a lock. This
caused a problem in `terraform console`, which would call unlock
regardless of error status.

This commit makes the local and remote backend consistently unlock the
state incase of error, and updates terraform console to check for errors
before trying to unlock the state.

The -backend-config flag expects a set of key-value pairs or a file

for blocks in the file and returns an error if they are encountered.

We previously intentionally removed support for the allow-missing-config

However, the option was not removed from the import command, and it is
widely used. This commit reintroduces support for importing with a
missing configuration by falling back to implying the provider FQN based
on the resource type.

Alisdair McDiarmid 820ed48813 command: Fix init flags silent exit bug
When using `-flag=value` with Powershell, unquoted values are broken
into separate arguments. This means that the following command:

  terraform init -backend-config=./backend.conf

is interpreted by Terraform as:

  terraform init -backend-config= ./backend.conf

This results in an empty backend-config setting (which is semantically
valid!) followed by a custom configuration path (pointing at a file).

Due to a bug where we could exit without printing diagnostics, this
would result in a silent failure that was very difficult to diagnose.

Alisdair McDiarmid 0d614a8d01 command/apply: Remove implicit init call
The positional argument passed to apply was once used to specify a
source for a Terraform module to fetch and initialize (#337). This
functionality was removed from the init command later (#15032) but not
completely removed from apply.

This code was non-functional but largely not harmful, except for a very
specific case: when passing an absolute path to a plan file as the
positional argument on Windows, the getter.Detect code would incorrectly
interpret the path as a URL. This caused init to fail and the apply
command would exit with code 1 but without diagnostics.

This commit removes this codepath, which fixes this bug, and should
otherwise have no effect on the supported behaviour of apply.

For remote modules, we display a separate list noting that they need to
be upgraded elsewhere, providing both the local module call name and the
module source address.

Martin Atkins 49e2e00231 command: terraform providers mirror
This new command is intended to make it easy to create or update a mirror
directory containing suitable providers for the current configuration,
producing a layout that is appropriate both for a filesystem mirror or,
if copied into the document root of an HTTP server, a network mirror.

This initial version is not customizable aside from being able to select
multiple platforms to install packages for.

Future iterations of this could include commands to turn the JSON index
generation on and off, or to instruct it to produce the unpacked directory
layout instead of the packed directory layout as it currently does. Both
of those options would make the generated directory unsuitable to be
a network mirror, but it would still work as a filesystem mirror.

In the long run this will hopefully form part of a replacement workflow to
terraform-bundle as a way to put copies of providers somewhere so we don't
need to re-download them every time, but some other changes will be needed
outside of just this command before that'd be true, such as adding support
for network and/or filesystem mirrors in Terraform Enterprise.

Martin Atkins 31a4b44d2e backend/local: treat output changes as side-effects to be applied
This is a baby-step towards an intended future where all Terraform actions
which have side-effects in either remote objects or the Terraform state
can go through the plan+apply workflow.

This initial change is focused only on allowing plan+apply for changes to
root module output values, so that these can be written into a new state
snapshot (for consumption by terraform_remote_state elsewhere) without
having to go outside of the primary workflow by running
"terraform refresh".

This is also better than "terraform refresh" because it gives an
opportunity to review the proposed changes before applying them, as we're
accustomed to with resource changes.

The downside here is that Terraform Core was not designed to produce
accurate changesets for root module outputs. Although we added a place for
it in the plan model in Terraform 0.12, Terraform Core currently produces
inaccurate changesets there which don't properly track the prior values.

We're planning to rework Terraform Core's evaluation approach in a
forthcoming release so it would itself be able to distinguish between the
prior state and the planned new state to produce an accurate changeset,
but this commit introduces a temporary stop-gap solution of implementing
the logic up in the local backend code, where we can freeze a snapshot of
the prior state before we take any other actions and then use that to
produce an accurate output changeset to decide whether the plan has
externally-visible side-effects and render any changes to output values.

This temporary approach should be replaced by a more appropriately-placed
solution in Terraform Core in a release, which should then allow further
behaviors in similar vein, such as user-visible drift detection for
resource instances.

Alisdair McDiarmid ca40107066 command/init: Better diagnostics for provider 404s
Fetching a default namespace provider from the public registry can
result in 404 Not Found error. This might be caused by a previously-
default provider moving to a new namespace, which means that the
configuration needs to be upgraded to use an explicit provider source.

This commit adds a more detailed diagnostic for this situation,
suggesting that the intended provider might be in a new namespace. The
recommended course of action is to run the 0.13upgrade command to
generate the correct required_providers configuration.

command: Unmanaged providers
This adds supports for "unmanaged" providers, or providers with process
lifecycles not controlled by Terraform. These providers are assumed to
be started before Terraform is launched, and are assumed to shut
themselves down after Terraform has finished running.

To do this, we must update the go-plugin dependency to v1.3.0, which
added support for the "test mode" plugin serving that powers all this.

As a side-effect of not needing to manage the process lifecycle anymore,
Terraform also no longer needs to worry about the provider's binary, as
it won't be used for anything anymore. Because of this, we can disable
the init behavior that concerns itself with downloading that provider's
binary, checking its version, and otherwise managing the binary.

This is all managed on a per-provider basis, so managed providers that
Terraform downloads, starts, and stops can be used in the same commands
as unmanaged providers. The TF_REATTACH_PROVIDERS environment variable
is added, and is a JSON encoding of the provider's address to the
information we need to connect to it.

This change enables two benefits: first, delve and other debuggers can
now be attached to provider server processes, and Terraform can connect.
This allows for attaching debuggers to provider processes, which before
was difficult to impossible. Second, it allows the SDK test framework to
host the provider in the same process as the test driver, while running
a production Terraform binary against the provider. This allows for Go's
built-in race detector and test coverage tooling to work as expected in
provider tests.

Unmanaged providers are expected to work in the exact same way as
managed providers, with one caveat: Terraform kills provider processes
and restarts them once per graph walk, meaning multiple times during
most Terraform CLI commands. As unmanaged providers can't be killed by
Terraform, and have no visibility into graph walks, unmanaged providers
are likely to have differences in how their global mutable state behaves
when compared to managed providers. Namely, unmanaged providers are
likely to retain global state when managed providers would have reset
it. Developers relying on global state should be aware of this.

Alisdair McDiarmid 62d826e066 command/init: Use full config for provider reqs
Relying on the early config for provider requirements was necessary in
Terraform 0.12, to allow the 0.12upgrade command to run after init
installs providers.

However in 0.13, the same restrictions do not apply, and the detection
of provider requirements has changed. As a result, the early config
loader gives incorrect provider requirements in some circumstances,
such as those in the new test in this commit.

Therefore we are changing the init command to use the requirements found
by the full configuration loader. This also means that we can remove the
internal initwd CheckCoreVersionRequirements function.

getproviders: move protocol compatibility functions into registry client (#24846)
* internal/registry source: return error if requested provider version protocols are not supported

* getproviders: move responsibility for protocol compatibility checks into the registry client

The original implementation had the providercache checking the provider
metadata for protocol compatibility, but this is only relevant for the
registry source so it made more sense to move the logic into
getproviders.

This also addresses an issue where we were pulling the metadata for
every provider version until we found one that was supported. I've
extended the registry client to unmarshal the protocols in
`ProviderVersions` so we can filter through that list, instead of
pulling each version's metadata.

a regression test.

Instead of using providers.tf as the default output file for the

configuration has no `required_providers` blocks at all, or has
multiple, the provider version requirements will be stored in the
versions.tf file.

We now also update the versions.tf file to set a `required_version`
attribute in the first `terraform` block, with value ">= 0.13". This
is similar to the behaviour of the 0.12upgrade command, and signals that
the configuration should not be used with older versions of Terraform.

Alisdair McDiarmid ae98bd12a7 command: Rework 0.13upgrade sub-command
This commit implements most of the intended functionality of the upgrade
command for rewriting configurations.

For a given module, it makes a list of all providers in use. Then it
attempts to detect the source address for providers without an explicit
source.

Once this step is complete, the tool rewrites the relevant configuration
files. This results in a single "required_providers" block for the
module, with a source for each provider.

Any providers for which the source cannot be detected (for example,
unofficial providers) will need a source to be defined by the user. The
tool writes an explanatory comment to the configuration to help with
this.

Martin Atkins c7fe6b9160 command/cliconfig: handle provider_installation block in JSON syntax
The CLI config can be written in both native HCL and HCL JSON syntaxes, so
the provider_installation block must be expressible using JSON too. Our
previous checks to approximate HCL 2-level strictness were too strict for
HCL JSON where things are more ambiguous even in HCL 2, so this includes
some additional relaxations if we detect that we're decoding an AST
produced from a JSON file.

This is still subject to the quirky ways HCL 1 handles JSON though, so
the JSON value must be structured in a way that doesn't trigger HCL's
heuristics that try to guess what is a block and what is an attribute.
(This is the issue that HCL 2 fixes by always decoding using a schema;
there's more context on this in:

Martin Atkins f5012c12da command/cliconfig: Installation methods, not installation sources
Unfortunately in the user model the noun "source" is already used for the
argument in the required_providers block to specify which provider to use,
so it's confusing to use the same noun to also refer to the method used to
obtain that provider.

In the hope of mitigating that confusion, here we use the noun "method",
as in "installation method", to talk about the decision between getting
a provider directly from its origin registry or getting it from some
mirror. This is distinct from the provider's "source", which is the
location where a provider _originates_ (prior to mirroring).

This noun is also not super awesome, but better than overloading an
existing term in the same feature.

Martin Atkins e872ec4461 command/cliconfig: Remove remnant extraArg checks in provider_installation
In the first pass of implementing this it was strict about what arguments

principles for CLI config where we tend to ignore unrecognized things to
allow for some limited kinds of future expansion without breaking
compatibility with older versions of Terraform that will be sharing the
same CLI configuration files with newer versions.

However, I'd removed the tracking of that prior to the initial commit. I
missed some leftover parts when doing that removal, so this cleans up the
rest of it.

Martin Atkins 8b75d1498f command/cliconfig: Use existing HTTP mirror source rather than new stub
An earlier commit added a redundant stub for a new network mirror source
that was already previously stubbed as HTTPMirrorSource.

This commit removes the unnecessary extra stub and changes the CLI config
handling to use it instead. Along the way this also switches to using a
full base URL rather than just a hostname for the mirror, because using
the usual "Terraform-native service discovery" protocol here doesn't isn't
as useful as in the places we normally use it (the mirror mechanism is
already serving as an indirection over the registry protocol) and using
a direct base URL will make it easier to deploy an HTTP mirror under
a path prefix on an existing static file server.

solve for the use-case where a particular invocation of Terraform needs

run as part of an automated test suite or other sort of automated
situation with different needs than normal use.

However, we accidentally had it only override the original singleton CLI
config file, while leaving the CLI configuration directory still enabled.
Now we'll take the CLI configuration out of the equation too, so that only
the single specified configuration file and any other environment-sourced
settings will be included.

terraform: return `initialization required` error when provider schemas not found (#24715)
A side effect of the various changes to the provider installer included losing the initialization required error message which would occur if a user removed or modified the .terraform directory.

Previously, plugin factories were created after the configuration was loaded, in terraform.NewContext. Terraform would compare the required providers (from config and state) to the available providers and return the aforementioned error if a provider was missing.

Provider factories are now loaded at the beginning of any terraform command, before terraform even loads the configuration, and therefore before terraform has a list of required providers.

This commit replaces the current error when a providers' schema cannot be found in the provider factories with the init error, and adds a command test (to plan tests, for no real reason other than that's what I thought of first).

Alisdair McDiarmid a5b3d497cc internal: Verify provider signatures on install
Providers installed from the registry are accompanied by a list of
checksums (the "SHA256SUMS" file), which is cryptographically signed to
allow package authentication. The process of verifying this has multiple
steps:

- First we must verify that the SHA256 hash of the package archive
  matches the expected hash. This could be done for local installations
  too, in the future.
- Next we ensure that the expected hash returned as part of the registry
  API response matches an entry in the checksum list.
- Finally we verify the cryptographic signature of the checksum list,
  using the public keys provided by the registry.

Each of these steps is implemented as a separate PackageAuthentication
type. The local archive installation mechanism uses only the archive
checksum authenticator, and the HTTP installation uses all three in the
order given.

The package authentication system now also returns a result value, which
is used by command/init to display the result of the authentication
process.

There are three tiers of signature, each of which is presented
differently to the user:

- Signatures from the embedded HashiCorp public key indicate that the
  provider is officially supported by HashiCorp;
- If the signing key is not from HashiCorp, it may have an associated
  trust signature, which indicates that the provider is from one of
  HashiCorp's trusted partners;
- Otherwise, if the signature is valid, this is a community provider.

Martin Atkins 8c928e8358 main: Consult local directories as potential mirrors of providers
This restores some of the local search directories we used to include when
searching for provider plugins in Terraform 0.12 and earlier. The
directory structures we are expecting in these are different than before,
so existing directory contents will not be compatible without
restructuring, but we need to retain support for these local directories
so that users can continue to sideload third-party provider plugins until
the explicit, first-class provider mirrors configuration (in CLI config)
is implemented, at which point users will be able to override these to
whatever directories they want.

This also includes some new search directories that are specific to the
operating system where Terraform is running, following the documented
layout conventions of that platform. In particular, this follows the
XDG Base Directory specification on Unix systems, which has been a
somewhat-common request to better support "sideloading" of packages via
standard Linux distribution package managers and other similar mechanisms.
While it isn't strictly necessary to add that now, it seems ideal to do
all of the changes to our search directory layout at once so that our
documentation about this can cleanly distinguish "0.12 and earlier" vs.
"0.13 and later", rather than having to document a complex sequence of
smaller changes.

Because this behavior is a result of the integration of package main with
package command, this behavior is verified using an e2etest rather than
a unit test. That test, TestInitProvidersVendored, is also fixed here to
create a suitable directory structure for the platform where the test is
being run. This fixes TestInitProvidersVendored.

Martin Atkins 958ea4f7d1 internal/providercache: Handle built-in providers
Built-in providers are special providers that are distributed as part of
Terraform CLI itself, rather than being installed separately. They always
live in the terraform.io/builtin/... namespace so it's easier to see that
they are special, and currently there is only one built-in provider named
"terraform".

Previous commits established the addressing scheme for built-in providers.
This commit makes the installer aware of them to the extent that it knows
not to try to install them the usual way and it's able to report an error
if the user requests a built-in provider that doesn't exist or tries to
impose a particular version constraint for a built-in provider.

For the moment the tests for this are the ones in the "command" package
because that's where the existing testing infrastructure for this
functionality lives. A later commit should add some more focused unit

* command: refactor testBackendState to write states.State

testBackendState was using the older terraform.State format, which is no
longer sufficient for most tests since the state upgrader does not
encode provider FQNs automatically. Users will run `terraform
0.13upgrade` to update their state to include provider FQNs in
resources, but tests need to use the modern state format instead of
relying on the automatic upgrade.

Martin Atkins de6c9ccec1 command/init: Move "vendored provider" test to e2etests
In the new design the ProviderSource is decided by package main, not by
the "command" package, and so making sure the vendor directory is included
is the responsibility of that package instead. Therefore we can no longer
test this at the "command" package level, but we'll retain a test for it
in e2etests to record that it isn't currently working, so that we have
a prompt to fix it before releasing.

Martin Atkins f35ebe2d65 internal/providercache: Fix incorrect logic in Installer.SetGlobalCacheDir
Due to some incomplete rework of this function in an earlier commit, the
safety check for using the same directory as both the target and the
cache was inverted and was raising an error _unless_ they matched, rather
than _if_ they matched.

This change is verified by the e2etest TestInitProviders_pluginCache,
which is also updated to use the new-style cache directory layout as part
of this commit.

Both of these are attempting to test -plugin-dir, which means we need some

the earlier installFakeProviderPackages to allow installing fake provider
packages to an arbitrary other directory.

Martin Atkins c81eebe0ac command/init: Fix TestInit_providerSource
This test is focused on making sure that the required_providers syntax

are tested in other tests such as TestInit_getUpgradePlugins.
2020-04-06 09:24:23 -07:00
Martin Atkins 14701b8300 command/init: Fix TestInit_getUpgradePlugins
This test now requires a bit of a different approach because it was
previously directly constructing a cache directory but we now use a
different directory layout.

Rather than manually constructing the new heirarchical directory layout
(which would've required a lot more inline code), this introduces a helper
function installFakeProviderPackages that installs a fake provider package
directly into the local cache directory associated with a Meta object,
with the correct directory layout.

Martin Atkins c4fb22863c command/init: Support -plugin-dir again
This is a slightly different approach than we used to take for this
option: rather than disabling the installer and causing all future
commands to look elsewhere for plugins, we'll now leave the installer
enabled by constrain it to only look at the given directories.

This is overall simpler because it doesn't require any special tracking
of the plugin directories for subsequent commands. Instead, the selections
file generated by the installer will record the versions it selected from
the specified directories, and we'll link them in to the local cache just
as we would normally so that other commands don't need to do anything
special to select the right plugins in either case.

Martin Atkins d40085f374 command: Make the tests compile again
They still aren't passing, but this is just enough updating to make the
test program compile successfully after the refactoring related to
provider installation. They are now using the mock provider source offered
by the getproviders package, which is similar but not totally identical
to the idea of mocking the entire installer as these tests used to do, and
so many of them need further adjustment to still be testing what they
intended to test under this new architecture.

Subsequent commits will gradually repair the failing tests.

* terraform: add helper functions for creating test state

testSetResourceInstanceCurrent and testSetResourceInstanceTainted are

used to set a resource in state. They work with current, non-deposed
resources with no dependencies.

testSetResourceInstanceDeposed can be used to set a desosed resource in state.

2020-04-06 09:24:23 -07:00
Martin Atkins 549aede792 Remove terraform.ResourceProvider, use providercache.Installer instead
Back when we first introduced provider versioning in Terraform 0.10, we
did the provider version resolution in terraform.NewContext because we
weren't sure yet how exactly our versioning model was going to play out
(whether different versions could be selected per provider configuration,
for example) and because we were building around the limitations of our
existing filesystem-based plugin discovery model.

However, the new installer codepath is new able to do all of the
selections up front during installation, so we don't need such a heavy
inversion of control abstraction to get this done: the command package can
select the exact provider versions and pass their factories directly
to terraform.NewContext as a simple static map.

The result of this commit is that CLI commands other than "init" are now
able to consume the local cache directory and selections produced by the
installation process in "terraform init", passing all of the selected
providers down to the terraform.NewContext function for use in
implementing the main operations.

This commit is just enough to get the providers passing into the
terraform.Context. There's still plenty more to do here, including to
repair all of the tests this change has additionally broken.

install process.

Alisdair McDiarmid 7165d6c429 command: Add state replace-provider subcommand
Terraform 0.13 will allow the installation of providers from various
sources. If a user updates their configuration to change the source of
an in-use provider (for example, if the provider namespace changes),
they will also need to update the state file accordingly.

This commit introduces a new `state replace-provider` subcommand which
supports this. All resources using the `from` provider will be updated
to use the `to` provider.

Previously, if a diagnostic context spanned multiple lines, any lines
which did not overlap with the highlight range would be displayed as
blank. This commit fixes the bug.

The problem was caused by the unconditional use of `PartitionAround` to
split the line into before/highlighted/after ranges. When two ranges
don't overlap, this method returns empty ranges, which results in a
blank line. Instead, we first check if the ranges do overlap, and if not
we print the entire line from the context.

Previously, diagnostic errors would display the filename and line

using the config loader.

This commit registers the manually parsed source as a synthetic
configuration file, so that the diagnostic formatter can look up the
source for the range with the error and display it.

Martin Atkins f899f5aa42 command/init: new error message for signature verification failure
Our initial Terraform 0.13.0 release will continue to support only the
hard-coded official HashiCorp signing key, with support for other keys to
follow in a later release once the trust infrastructure is in place to
support that.

This change is intended to (marginally) improve the UX for a possible
future situation where a HashiCorp-distributed provider makes a released
signed with a new key and a prior version of Terraform ends up trying to
install it due to incorrect version constraints. With this new text we
hope to give the user a better prompt for onward troubleshooting, but
in a sort of hedging way because we have not yet finalized the details of
how new keys might roll out in practice.

Hopefully a user seeing this message would consult the release notes for
Terraform itself and for the provider in question and find some
as-yet-undetermined information about how to proceed.

If the decentralized trust model design comes together before the v0.13.0
release then we may make further amendments here to prepare for that, but
that work should not block the v0.13.0 release if other work concludes
first.

a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings).

The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN. This is fine for now as we are only working with default assumption.

Initial steps towards AbsProviderConfig/LocalProviderConfig separation (#23978)
* Introduce "Local" terminology for non-absolute provider config addresses

In a future change AbsProviderConfig and LocalProviderConfig are going to
become two entirely distinct types, rather than Abs embedding Local as
written here. This naming change is in preparation for that subsequent
work, which will also include introducing a new "ProviderConfig" type
that is an interface that AbsProviderConfig and LocalProviderConfig both
implement.

This is intended to be largely just a naming change to get started, so
we can deal with all of the messy renaming. However, this did also require
a slight change in modeling where the Resource.DefaultProviderConfig
method has become Resource.DefaultProvider returning a Provider address
directly, because this method doesn't have enough information to construct
a true and accurate LocalProviderConfig -- it would need to refer to the
configuration to know what this module is calling the provider it has
selected.

In order to leave a trail to follow for subsequent work, all of the
changes here are intended to ensure that remaining work will become
obvious via compile-time errors when all of the following changes happen:
- The concept of "legacy" provider addresses is removed from the addrs
  package, including removing addrs.NewLegacyProvider and
  addrs.Provider.LegacyString.
- addrs.AbsProviderConfig stops having addrs.LocalProviderConfig embedded
  in it and has an addrs.Provider and a string alias directly instead.
- The provider-schema-handling parts of Terraform core are updated to
  work with addrs.Provider to identify providers, rather than legacy
  strings.

In particular, there are still several codepaths here making legacy
provider address assumptions (in order to limit the scope of this change)
but I've made sure each one is doing something that relies on at least
one of the above changes not having been made yet.

* addrs: ProviderConfig interface

In a (very) few special situations in the main "terraform" package we need
to make runtime decisions about whether a provider config is absolute
or local.

We currently do that by exploiting the fact that AbsProviderConfig has
LocalProviderConfig nested inside of it and so in the local case we can
just ignore the wrapping AbsProviderConfig and use the embedded value.

In a future change we'll be moving away from that embedding and making
these two types distinct in order to represent that mapping between them
requires consulting a lookup table in the configuration, and so here we
introduce a new interface type ProviderConfig that can represent either
AbsProviderConfig or LocalProviderConfig decided dynamically at runtime.

This also includes the Config.ResolveAbsProviderAddr method that will
eventually be responsible for that local-to-absolute translation, so
that callers with access to the configuration can normalize to an
addrs.AbsProviderConfig given a non-nil addrs.ProviderConfig. That's
currently unused because existing callers are still relying on the
simplistic structural transform, but we'll switch them over in a later
commit.

* rename LocalType to LocalName

The formatter in `command/format/state.go`, when formatting a resource
with an aliased provider, was looking for a schema with the alias (ie,
test.foo), but the schemas are only listed by provider type (test).
Update the state formatter to lookup schemas by provider type only.

Some of the show tests (and a couple others) were not properly cleaning
up the created tmpdirs, so I fixed those. Also, the show tests are using
a statefile named `state.tfstate`, but were not passing that path to the
show command, so we were getting some false positives (a `show` command
that returns `no state` exits 0).

With the latest version of `terraform-config-inspect`, the
required_providers attribute can now be a string or an object with
attributes "source" and "version". This change allows parsing the
version constraint from the new object while ignoring any given source attribute.

command: use backend config from state when backend=false is used. (#23802)
* command: use backend config from state when backend=false is used.

When a user runs `terraform init --backend=false`, terraform should
inspect the state for a previously-configured backend, and use that
backend, ignoring any backend config in the current configuration. If no
backend is configured or there is no state, return a local backend.

James Bardin 98c02ac114 remove stale dependencies on `state mv`
Clear any Dependencies if there is an entry matching a `state mv` from
address. While stale dependencies won't directly effect any current
operations, clearing the list will allow them to be recreated in their
entirety during refresh. This will help future releases that may rely
solely on the pre-calculated dependencies for destruction ordering.

The configs package is aware of provider name and type (which are the

release), and should be the source of truth for a provider config
address. This is an intermediate step; the next step will change the returned types to something based in the configs package.

Martin Atkins c06675c616 command: New -compact-warnings option
When warnings appear in isolation (not accompanied by an error) it's
reasonable to want to defer resolving them for a while because they are
not actually blocking immediate work.

However, our warning messages tend to be long by default in order to
include all of the necessary context to understand the implications of
the warning, and that can make them overwhelming when combined with other
output.

As a compromise, this adds a new CLI option -compact-warnings which is
supported for all the main operation commands and which uses a more
compact format to print out warnings as long as they aren't also
accompanied by errors.

The default remains unchanged except that the threshold for consolidating
warning messages is reduced to one so that we'll now only show one of
each distinct warning summary.

Full warning messages are always shown if there's at least one error
included in the diagnostic set too, because in that case the warning
message could contain additional context to help understand the error.

Martin Atkins 7081c26e54 command: Don't show more than two of the same warning
Some of our warnings are produced in response to particular configuration
constructs which might appear many times across a Terraform configuration.
To avoid the warning output dwarfing all of the other output, we'll use
ConsolidateWarnings to limit each distinct warning summary to appear at
most twice, and annotate the final one in the sequence with an additional
paragraph noting that some number of them have been hidden.

This is intended as a compromise to ensure that these warnings are still
seen and noted but to help ensure that we won't produce so many of them
as to distract from other output that appears alongside them.

This applies only to warnings relating to specific configuration ranges;
errors will continue to be shown individually, and sourceless warnings
(which are rare in Terraform today) will likewise remain ungrouped because
they are less likely to be repeating the same statement about different
instances of the same problem throughout the configuration.

Meta.backendConfig was incorrectly treating the second return value from

errors.

This had confusing results because it still returned that
tfdiags.Diagnostics value in its own diagnostics return value, causing the
caller to see warnings even though the backendConfig function had taken
the error codepath.

Martin Atkins 7db2825646 command/format: multi-line rendering for unchanged strings
We have a special treatment for multi-line strings that are being updated
in-place where we show them across multiple lines in the plan output, but
we didn't use that same treatment for rendering multi-line strings in
isolation such as when they are being added for the first time.

Here we detect when we're rendering a multi-line string in a no-change
situation and render it using the diff renderer instead, using the same
value for old and new and thus producing a multi-line result without any
diff markers at all.

This improves consistency between the change and no-change cases, and
makes multi-line strings (such as YAML in block mode) readable in all
cases.

James Bardin 46dbb3dde5 use Dependencies to connect creator and destroyer
The DestroyEdgeTransformer cannot determine ordering from the graph when
the destroyers are from orphaned resources, because there are no
references to resolve. The new stored Dependencies provides what we need
to connect the instances in this case.

We also add the StateDependencies method directly in the
GraphNodeResourceInstance interface, since all instances already
implement this, and we don't need another optional interface to check.

The old code in DestroyEdgeTransformer may no longer be needed in the
long run, but that can be determined separately, since too many of the
tests start with an incomplete state and rely on the Dependencies being
determined from the configuration alone.

Martin Atkins d0cbbb6a00 command/format: Remove defunct "Plan" type and associated symbols
This "Plan" type, along with the other types it directly or indirectly
embeds and the associated functions, are adaptations of the
flatmap-oriented plan renderer logic from Terraform 0.11 and prior.

The current diff rendering logic is in diff.go, and so the contents of the
plan.go file are defunct apart from the DiffActionSymbol function that
both implementations share. Therefore here we move DiffActionSymbol into
diff.go and then remove plan.go entirely, in the interests of dead code
removal.

Martin Atkins 9a62ab3014 command: "terraform show" renders plans like "terraform plan"
During the Terraform 0.12 work we briefly had a partial update of the old
Terraform 0.11 (and prior) diff renderer that could work with the new
plan structure, but could produce only partial results.

We switched to the new plan implementation prior to release, but the
"terraform show" command was left calling into the old partial
implementation, and thus produced incomplete results when rendering a
saved plan.

Here we instead use the plan rendering logic from the "terraform plan"
command, making the output of both identical.

Unfortunately, due to the current backend architecture that logic lives
inside the local backend package, and it contains some business logic
around state and schema wrangling that would make it inappropriate to move
wholesale into the command/format package. To allow for a low-risk fix to
the "terraform show" output, here we avoid some more severe refactoring by
just exporting the rendering functionality in a way that allows the
"terraform show" command to call into it.

In future we'd like to move all of the code that actually writes to the
output into the "command" package so that the roles of these components
are better segregated, but that is too big a change to block fixing this
issue.

command/jsonplan: fix bug with nested modules output (#23092)
`marshalPlannedValues` builds a map of modules to their children in
order to output the resource changes in a tree. The map was built from
the list of resource changes. However if a module had no resources
itself, and only called another module (a very normal case), that module
would not get added to the map causing none of its children to be
output in `planned_values`.

each module, even those without resources, would be added.

Martin Atkins 8664749b59 backend: Allow certain commands to opt out of required variable checks
Terraform Core expects all variables to be set, but for some ancillary
commands it's fine for them to just be set to placeholders because the
variable values themselves are not key to the command's functionality
as long as the terraform.Context is still self-consistent.

For such commands, rather than prompting for interactive input for
required variables we'll just stub them out as unknowns to reflect that
they are placeholders for values that a user would normally need to
provide.

This achieves a similar effect to how these commands behaved before, but
without the tendency to produce a slightly invalid terraform.Context that
would fail in strange ways when asked to run certain operations.

Martin Atkins e21f0fa61e backend/local: Handle interactive prompts for variables in UI layer
During the 0.12 work we intended to move all of the variable value
collection logic into the UI layer (command package and backend packages)
and present them all together as a unified data structure to Terraform
Core. However, we didn't quite succeed because the interactive prompts
for unset required variables were still being handled _after_ calling
into Terraform Core.

Here we complete that earlier work by moving the interactive prompts for
variables out into the UI layer too, thus allowing us to handle final
validation of the variables all together in one place and do so in the UI
layer where we have the most context still available about where all of
these values are coming from.

This allows us to fix a problem where previously disabling input with
-input=false on the command line could cause Terraform Core to receive an
incomplete set of variable values, and fail with a bad error message.

As a consequence of this refactoring, the scope of terraform.Context.Input
is now reduced to only gathering provider configuration arguments. Ideally
that too would move into the UI layer somehow in a future commit, but
that's a problem for another day.

Martin Atkins 39e609d5fd vendor: switch to HCL 2.0 in the HCL repository
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.

This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.

For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.

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.

This is just a wholesale move of the CLI configuration types and functions

This commit alone doesn't really achieve anything, but in future commits
we'll expand the functionality in this package.

command/init: omit a warning if -backend-config is used with no backend (#22164)
* command/init: omit a warning if -backend-config is used with no backend
block

Terraform would silently accept - and swallow - `-backend-config` on the
CLI when there was no `backend` block. Since it is mostly expected to
override existing backend configuration, terraform
should omit a warning if there is no backend configuration to
override.

If the user intended to override the default (local) backend
configuration, they can first add a `backend` block to the `terraform` block to silence the warning (or just ignore it):

```hcl
terraform {
  backend "local" {}
}
```

command/show (json): marshal the state snapshot included with the plan file (#21597)
* command/show: marshal the state snapshot from the planfile

The planfile contains a state snapshot with certain resources updated
(outputs and datasources). Previously `terraform show -json PLANFILE`
was using the current state instead of the state inside the plan as
intended.

This caused an issue when the state included a terraform_remote_state
datasource. The datasource's state gets refreshed - and therefore
upgraded to the current state version - during plan, but that won't
persist to state until apply.

* update comment to reflect new return

* command/show -json: fix panic

afterUnknown should return only bools, not values.

* command/jsonplan: let's delete some redundant code!

the plan output was somewhat inconsistent with return values for
"after_unknown". This strives to fix that. If all "after" values are
known, return an empty object instead of iterating over values.

Also fixing some typos and general copypasta.

Martin Atkins d512584497 command/jsonplan: Don't panic with mixtures of known/unknown/empty
The omitUnknowns and unknownAsBool functions were previously trying hard
to preserve the same collection types in the output as they had in the
input, by attempting to keep everything matched up so that the results
would be valid.

Unfortunately, this turns out to be a harder problem than we originally
thought: it was possible for a collection value going in to produce
inconsistent element types out (and thus a panic) in the following
situations:
- when a collection with mixed known and unknown values was passed in
  to omitUnknowns.
- when a collection of collections where the inner collections are a
  mixture of empty and not empty in unknownAsNull.

The results of these functions are only used to marshal to JSON anyway,
and JSON serialization can't distinguish between the three sequence types
or the two mapping types, so in practice we can just standardize on
converting all sequences to tuple and all mappings to object here and not
change the resulting output at all, and then we don't have to worry about
making sure all of the inner types get preserved exactly.

A nice consequence of that relaxation is that we can now do what we
originally wanted to do with unknownAsBool, and omit map keys and
object attributes altogether if their values would've been false,
producing a much more compact result. This is easiest to do now when
there's only one known user of this JSON plan output, and we know that
user will treat both false and omitted as the same here.
