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.

internal/initwd: fix panics with relative submodules in DirFromModule (#25250)
* internal/initwd: fix panics with relative submodules in DirFromModule

There were two related issues here:

1. panic with any local module with submodules
1. panic with a relative directory that was above the workdir ("../")

The first panic was caused by the local installer looking up the root
module with the (nonexistant) key "root.", instead of "".

The second panic was caused by the installer trying to determine the
relative path from ".". This was fixed by detecting "." as the source
path and using the absolute path for the call to filepath.Rel.

Added test cases for both panics and updated the existing e2e tests with
the correct install paths.

Martin Atkins 072c6d9aed internal/copydir: Factor out our recursive directory copy for reuse
We've previously been copying this function around so it could remain
unexported while being used in various packages. However, it's a
non-trivial function with lots of specific assumptions built into it, so
here we'll put it somewhere that other packages can depend on it _and_
document the assumptions it seems to be making for future reference.

As a bonus, this now uses os.SameFile to detect when two paths point to
the same physical file, instead of the slightly buggy local implementation
we had before which only worked on Unix systems and did not correctly
handle when the paths were on different physical devices.

The copy of the function I extracted here is the one from internal/initwd,
so this commit also includes the removal of that unexported version and
updating the callers in that package to use at at this new location.

Kristin Laemmert 68dfc3046d backend/remote-state: etcdv3, oss, and manta acc tests should fail
faster

The acceptance tests for etcdv3, oss and manta were not validating
required env variablea, chosing to assume that if one was running
acceptance tests they had already configured the credentials.

It was not always clear if this was a bug in the tests or the provider,
so I opted to make the tests fail faster when required attributes were
unset (or "").

filepath.EvalSymlinks is our friend! The code already does this, the
tests needed to be updated to do the same.

Martin Atkins c5285021fa internal/initwd: Test that version is rejected for local modules
This was already working, but since that codepath is separate from the
go-getter install codepath it's helpful to have a separate test for it,
in addition to the existing one for go-getter modules.

internal/initwd: follow local module path symlink (#21063)
* internal/initwd: follow local module path symlink

Fixes #21060

While a previous commit fixed a problem when the local module directory
contained a symlink, it did not account for the possibility that the
entire directory was a symlink.

configs/configupgrade: detect possible relative module sources (#20646)
* configs/configupgrade: detect possible relative module sources

If a module source appears to be a relative local path but does not have
a preceding ./, print a #TODO message for the user.

* internal/initwd: limit go-getter detectors to those supported by terraform
* internal/initwd: move isMaybeRelativeLocalPath check into getWithGoGetter

To avoid making two calls to getter.Detect, which potentially makes
non-trivial API calls, the "isMaybeRelativeLocalPath" check was moved to
a later step and a custom error type was added so user-friendly
diagnostics could be displayed in the event that a possible relative local
path was detected.

internal/initwd: identify possible relative module sources
Identify module sources that look like relative paths ("child" instead
of "./child", for example) and surface a helpful error.

Previously, such module sources would be passed to go-getter, which
would fail because it was expecting an absolute, or properly relative,
path. This commit moves the check for improper relative paths sooner so
a user-friendly error can be displayed.

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.
