All run variables remain encoded as strings in the API but will now be expressed as an HCL value to be evaluated correctly by the remote terraform. Previously, only strings were supported.
Examples:
string: `"quoted literal"` (strings must be quoted)
map: `{ foo = "bar" }`
list: `["foo", "bar"]`
bool: `true`
null: `null`
number: `0.0001`
This requires the API to anticipate that all run variables will be HCL values
Error diags from c.installModules() no longer cause getModules() to exit early.
Whether installModules completed successfully, errored, or was cancelled, we
try to update the manifest as best we can, preferring incomplete information
to none.
Earlier work to make "terraform init" interruptible made the getproviders
package context-aware in order to allow provider installation to be cancelled.
Here we make a similar change for module installation, which is now also
cancellable with SIGINT. This involves plumbing context through initwd and
getmodules. Functions which can make network requests now include a context
parameter whose cancellation cancels those requests.
Since the module installation code is shared, "terraform get" is now
also interruptible during module installation.
* convert uses of worspaces.operations into workspaces.executionMode
The cloud package currently uses a deprecated API on workspaces to determine a workspace's execution mode.
Deprecated: Operations (boolean)
New hotness: Execution mode (string - "local", "remote", or "agent")
More details: https://www.terraform.io/docs/cloud/api/workspaces.html#request-body
All uses of Operations field coming from the client (within the cloud package) should be converted to the appropriate ExecutionMode equivalent.
Also, we need to update all acknowledgment of operations field on the tests that are testing the behavior of workspaces.

We have a few dependencies that are such a significant part of Terraform's
behavior that they will often be the root cause of or the solution to a
bug reported against Terraform.
As a small quality-of-life improvement to help with diagnosing those,
we'll now report the selected versions for each of these so-called
"interesting" dependencies as part of our initial trace log output during
Terraform startup.
The goal here is that when someone opens a bug report, and includes the
trace log as our bug report template requests, we'll be able to see at a
glance which versions of these dependencies were involved, instead of
having to manually cross-reference in the go.mod file of the reported main
Terraform CLI version.
This does slightly grow the general overhead of the logs, but as long as
we keep this set of interesting dependencies relatively small it shouldn't
present any significant problem in typical usage.
For Terraform Cloud users using the 'remote' backend, the existing
'pattern' prompt should work just fine - but because their workspaces
are already present in TFC, the 'migration' here is really just
realigning their local workspaces with Terraform Cloud. Instead of
forcing users to do the mental gymnastics of what it means to migrate
from 'prefix' - and because their remote workspaces probably already exist and
already conform to Terraform Cloud's naming concerns - streamline the
process for them and calculate the necessary pattern to migrate as-is,
without any user intervention necessary.
After migrating to TFC with renamed workspaces, automatically select
what was the previous current workspace on behalf of the user. We don't
need to make the user reselect.
Note these change do break the internal/cloud/e2e tests; they are in a
sad state that needs adjusting anyway, so I'm not updating them for
these changes at this time.
cty: The documented definition and comparison logic of cty.Number is now
refined to acknowledge that its true range is limited only to values
that have both a binary floating point and decimal representation,
because cty values are primarily designed to traverse JSON serialization
where numbers are always defined as decimal strings.
In particular, that means that two cty.Number values now always compare
as equal if their representation in JSON (under cty's own JSON encoder)
would be equal, even though the decimal approximation we use for that
conversion is slightly lossy. This pragmatic compromise avoids confusing
situations where a round-trip through JSON serialization (or other
serializations that use the same number format) may produce a value that
doesn't compare equal to the original.
This new definition of equals should not cause any significant behavior
change for any integer in our in-memory storage range, but may cause
some fractional values to compare equal where they didn't before if they
differ only by a small fraction.
