Martin Atkins e70ab09bf1 command: new cache directory .terraform/providers for providers
Terraform v0.10 introduced .terraform/plugins as a cache directory for
automatically-installed plugins, Terraform v0.13 later reorganized the
directory structure inside but retained its purpose as a cache.

The local cache used to also serve as a record of specifically which
packages were selected in a particular working directory, with the intent
that a second run of "terraform init" would always select the same
packages again. That meant that in some sense it behaved a bit like a
local filesystem mirror directory, even though that wasn't its intended
purpose.

Due to some unfortunate miscommunications, somewhere a long the line we
published some documentation that _recommended_ using the cache directory
as if it were a filesystem mirror directory when working with Terraform
Cloud. That was really only working as an accident of implementation
details, and Terraform v0.14 is now going to break that because the source
of record for the currently-selected provider versions is now the
public-facing dependency lock file rather than the contents of an existing
local cache directory on disk.

After some consideration of how to move forward here, this commit
implements a compromise that tries to avoid silently doing anything
surprising while still giving useful guidance to folks who were previously
using the unsupported strategy. Specifically:

- The local cache directory will now be .terraform/providers rather than
  .terraform/plugins, because .terraform/plugins is effectively "poisoned"
  by the incorrect usage that we can't reliably distinguish from prior
  version correct usage.

- The .terraform/plugins directory is now the "legacy cache directory". It
  is intentionally _not_ now a filesystem mirror directory, because that
  would risk incorrectly interpreting providers automatically installed
  by Terraform v0.13 as if they were a local mirror, and thus upgrades
  and checksum fetches from the origin registry would be blocked.

- Because of the previous two points, someone who _was_ trying to use the
  legacy cache directory as a filesystem mirror would see installation
  fail for any providers they manually added to the legacy directory.

  To avoid leaving that user stumped as to what went wrong, there's a
  heuristic for the case where a non-official provider fails installation
  and yet we can see it in the legacy cache directory. If that heuristic
  matches then we'll produce a warning message hinting to move the
  provider under the terraform.d/plugins directory, which is a _correct_
  location for "bundled" provider plugins that belong only to a single
  configuration (as opposed to being installed globally on a system).

This does unfortunately mean that anyone who was following the
incorrectly-documented pattern will now encounter an error (and the
aforementioned warning hint) after upgrading to Terraform v0.14. This
seems like the safest compromise because Terraform can't automatically
infer the intent of files it finds in .terraform/plugins in order to
decide automatically how best to handle them.

The internals of the .terraform directory are always considered
implementation detail for a particular Terraform version and so switching
to a new directory for the _actual_ cache directory fits within our usual
set of guarantees, though it's definitely non-ideal in isolation but okay
when taken in the broader context of this problem, where the alternative
would be silent misbehavior when upgrading.

Martin Atkins e1cf0ac801 internal/depsfile: Control how the "hashes" value is formatted
Previously we were just letting hclwrite do its default formatting
behavior here. The current behavior there isn't ideal anyway -- it puts
big data structures all on one line -- but even ignoring that our goal
for this file format is to keep things in a highly-normalized shape so
that diffs against the file are clear and easy to read.

With that in mind, here we directly control how we write that value into
the file, which means that later changes to hclwrite's list/set
presentation won't affect it, regardless of what form they take.

Martin Atkins b3f5c7f1e6 command/init: Read, respect, and update provider dependency locks
This changes the approach used by the provider installer to remember
between runs which selections it has previously made, using the lock file
format implemented in internal/depsfile.

This means that version constraints in the configuration are considered
only for providers we've not seen before or when -upgrade mode is active.

Kristin Laemmert 04be220f5f deprecate helper/copy
helper/copy CopyDir was used heavily in tests. It differes from
internal/copydir in a few ways, the main one being that it creates the
dst directory while the internal version expected the dst to exist
(there are other differences, which is why I did not just switch tests
to using internal's CopyDir).

I moved the CopyDir func from helper/copy into command_test.go; I could
also have moved it into internal/copy and named it something like
CreateDirAndCopy so if that seems like a better option please let me
know.

helper/copy/CopyFile was used in a couple of spots so I moved it into
internal, at which point I thought it made more sense to rename the
package copy (instead of copydir).

There's also a `go mod tidy` included.

remove LegacyProvider (#26433) 2020-10-05 08:33:49 -04:00
Martin Atkins 59b116f7bf command/init: Remove support for legacy provider addresses
We no longer need to support 0.12-and-earlier-style provider addresses
because users should've upgraded their existing configurations and states
on Terraform 0.13 already.

For now this is only checked in the "init" command, because various test
shims are still relying on the idea of legacy providers the core layer.
However, rejecting these during init is sufficient grounds to avoid
supporting legacy provider addresses in the new dependency lock file
format, and thus sets the stage for a more severe removal of legacy
provider support in a later commit.

Martin Atkins 0b734a2803 command: Make provider installation interruptible
In earlier commits we started to make the installation codepath
context-aware so that it could be canceled in the event of a SIGINT, but
we didn't complete wiring that through the API of the getproviders
package.

Here we make the getproviders.Source interface methods, along with some
other functions that can make network requests, take a context.Context
argument and act appropriately if that context is cancelled.

The main providercache.Installer.EnsureProviderVersions method now also
has some context-awareness so that it can abort its work early if its
context reports any sort of error. That avoids waiting for the process
to wind through all of the remaining iterations of the various loops,
logging each request failure separately, and instead returns just
a single aggregate "canceled" error.

We can then set things up in the "terraform init" and
"terraform providers mirror" commands so that the context will be
cancelled if we get an interrupt signal, allowing provider installation
to abort early while still atomically completing any local-side effects
that may have started.

Alisdair McDiarmid 9f824c53a5 command: Better in-house provider install errors
When init attempts to install a legacy provider required by state and
fails, but another provider with the same type is successfully
installed, this almost definitely means that the user is migrating an
in-house provider. The solution here is to use the `terraform state
replace-provider` subcommand.

This commit makes that next step clearer, by detecting this specific
case, and displaying a list of commands to fix the existing state
provider references.

Alisdair McDiarmid 45437721c9 command: Add test for backend config validation 2020-08-26 11:37:11 -04:00
Alisdair McDiarmid 677aabc767 command: Fix backend config override validation
When loading a backend config override file, init was doing two things
wrong:

- First, if the file failed to parse, we accidentally didn't return,
  which caused a panic due to the parsed body being nil;
- Secondly, we were overzealous with the validation of the file,
  allowing only attributes. While most backend configs are attributes
  only, the enhanced remote backend body also contains a `workspaces`
  block, which we need to support here.

This commit fixes the first bug with an early return and adds test cases
for missing file and intentionally-blank filename (to clear the config).

We also add a schema validation for the backend block, based on the
backend schema itself. This requires constructing an HCL body schema so
that we can call `Content` and check for diagnostic errors.

The result is more useful errors when an invalid backend config override
file is used, while also supporting the enhanced remote backend config
fully.

Does not include tests specific to the remote backend, because the
mocking involved to allow the backend to fully initialize is too
involved to be worth it.

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.

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

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.

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 9263b28e99 command/init: Improve diags for legacy providers
When initializing a configuration which refers to re-namespaced legacy
providers, we attempt to detect this and display a diagnostic message.
Previously this message would direct the user to run the 0.13upgrade
command, but without specifying in which directories.

This commit detects which modules are using the providers in question,
and for local modules displays a list of upgrade commands which specify
the source directories of these modules.

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.

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.

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.

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 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
tests here in the internal/providercache package, too.

in e2etests to record that it isn't currently working, so that we have
a prompt to fix it before releasing.

function installFakeProviderPackages that installs a fake provider package
directly into the local cache directory associated with a Meta object,
with the correct directory layout.

so many of them need further adjustment to still be testing what they

The formatter in `command/format/state.go`, when formatting a resource

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).

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" {}
}
```

James Bardin c017149b31 don't store prepared backend config
The backend gets to "prepare" the configuration before Configure is
called, in order to validate the values and insert defaults. We don't
want to store this value in the "config state", because it will often
not match the raw config after it is prepared, forcing unecessary
backend migrations during init.

Since PrepareConfig is always called before Configure, we can store the
config value directly, and assume that it will be prepared in the same
manner each time.

Martin Atkins 63fa1ac418 vendor: go get github.com/hashicorp/hcl2@master
This includes a small fix to ensure the parser doesn't produce an invalid
body for block parsing syntax errors, and instead produces an incomplete
result that calling applications like Terraform can still analyze.

The problem here was affecting our version-constraint-sniffing code, which
intentionally tried to find a core version constraint even if there's a
syntax error so that it can report that a new version of Terraform is a
likely cause of the syntax error. It was working in most cases, unless
it was the "terraform" block itself that contained the error, because then
we'd try to analyze a broken hcl.Block with a nil body.

This includes a new test for "terraform init" that exercises this
recovery codepath.

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 8c54da0ad2 command: TestInit_fromModule_explicitDest guard against other tests
Some other test is leaving behind a terraform.tfstate after it concludes,
which can cause this test to fail in a strange way due to picking up
extra provider requirements from that state.

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.
