Add reasonable default behavior to the mock provider, so that may do not
need to depend on the idiosyncrasies of the old (though updated) test
testDiffFn and to a lesser extend the testApplyFn. This behavior is
based directly upon the documented resource lifecycle, rather
than be an ad-hoc collection of behaviors from old tests.
As a proof of concept, remove all uses of testDiffFn from the plan
context tests that don't cause the tests to fail.
The revision field is only populated on dev builds so this means
most releases of Terraform have an empty "terraform_revision" field
in the JSON output. Since we recommend developers use go tooling
to `go build` this tool when developing, the revision is not useful
data and so it is removed.
There are a few places where we want to perform some transformation on a
cty.Value, but require information from the schema. Rather than create
bespoke functions to walk the cty.Value and schema in concert, we can
provide Attribute information from a cty.Path allowing the use of
Value.Transform in these cases.
This allows up to detect an unset value from the zero value so that
defaults can be implemented, while still allowing tests to return
specific values of their choosing.
When running state mv with a resource source, but the destination
fails, provide a hint that the source is a resource (not an instance)
in case the user means to address it this way
Using the addrTo after it has failed its check means <invalid>/no
address will be printed. Change this throughout, but particularly
add a test for the origin issue for this.
Because the destroy plan only creates the necessary changes for apply to
remove all the resources, it does no reading of resources or data
sources, leading to stale data in the state. In most cases this is not a
problem, but when a provider configuration is using resource values, the
provider may not be able to run correctly during apply. In prior
versions of terraform, the implicit refresh that happened during
`terraform destroy` would update the data sources and remove missing
resources from state as required.
The destroy plan graph has a minimal amount of information, so it is not
feasible to work the reading of resources into the operation without
completely replicating the normal plan graph, and updating the plan
graph and all destroy node implementation is also a considerable amount
of refactoring. Instead, we can run a normal plan which is used to
refresh the state before creating the destroy plan. This brings back
similar behavior to core versions prior to 0.14, and the refresh can
still be skipped using the `-refresh=false` cli flag.
The context used for Stop is more appropriately tied to the lifetime of
the provisioner rather than a call to the ProvisionResource method. In
some cases Stop can be called before ProvisionResource, causing a panic
the provisioner. Rather than adding nil checks to the CancelFunc call
for Stop, create a base context to use for cancellation with both Stop
and Close methods.
Recent changes to the human-readable rendering of outputs and console
values led to long integer values being presented in scientific
notation (e.g. 1.2345678e+07). While technically correct, this is an
unusual way to present integer values.
This commit changes the formatting mode to 'f', which never uses
scientific notation and displays integer values as a sequence of digits
instead (e.g. 12345678).
This variable mechanism was replaced long ago with a explicit `Allow
destroy plans` setting on a Terraform Cloud workspace, and no longer
does anything: https://www.terraform.io/docs/cloud/workspaces/settings.html#destruction-and-deletion
Rather than mention this new mechanism at all though, I've removed the
requisite from here entirely - the reason being that a consideration
like this is no different from other permission concerns (e.g. "You must
have Apply permission on a workspace to `apply`"), and without
enumerating _all_ of these here - which doesn't seem appropriate - we
just remove this concern entirely.
