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.
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.
Binding a sensitive value to a variable with custom validation rules
would cause a panic, as the validation expression carries the sensitive
mark when it is evaluated for truthiness. This commit drops the marks
before testing, which fixes the issue.
If the remote backend is connected to a Terraform Cloud workspace in
local operations mode, we disable the version check, as the remote
Terraform version is meaningless.
...and also shrink the explanation for alternate sharing approaches, a bit.
Actually, it looks like I already half-adopted it by accident. 😬 But this
commit adds it to the sidebar under "State", so users can browse to it. I'm
leaving the URL alone, because it's not urgent and we'll need to adjust a large
swath of URLs at some point anyway.
This change effectively stops presenting `terraform` as a provider in the normal
sense, and reduces /docs/providers/terraform/index.html to a ghost page in the
language section (to avoid breaking links for the time being). The message a
reader should get is that Terraform has one special built-in data source where
you don't need to think about the provider or its version.
