Since an early version of Terraform, the `destroy` command has always
had the `-force` flag to allow an auto approval of the interactive
prompt. 0.11 introduced `-auto-approve` as default to `false` when using
the `apply` command.
The `-auto-approve` flag was introduced to reduce ambiguity of it's
function, but the `-force` flag was never updated for a destroy.
People often use wrappers when automating commands in Terraform, and the
inconsistency between `apply` and `destroy` means that additional logic
must be added to the wrappers to do similar functions. Both commands are
more or less able to run with similar syntax, and also heavily share
their code.
This commit updates the command in `destroy` to use the `-auto-approve` flag
making working with the Terraform CLI a more consistent experience.
We leave in `-force` in `destroy` for the time-being and flag it as
deprecated to ensure a safe switchover period.
The plan shutdown test often fail on slow CI hosts, becase the plan
completes befor the main thread can cancel it. Since attempting to make
the MockProvider concurrent proved too invasive for now, just slow the
test down a bit to help ensure Stop gets called.
Similar to NodeApplyableOuptut, NodeDestroyableOutputs also need to stay
in the graph if any ancestor nodes
Use the same GraphNodeTargetDownstream method to keep them from being
pruned, since they are dependent on the output node and all its
descendants.
github.com/joyent/triton-go replaced a bunch of other dependencies quite
some time ago, but the replaced dependencies were never removed. This
commit removes them from the vendor manifest and the vendor/ directory.
The id attribute can be missing during the destroy operation.
While the new destroy-time ordering of outputs and locals should prevent
resources from having their id attributes set to an empty string,
there's no reason to error out if we have the canonical ID field
available.
This still interrogates the attributes map first to retain any previous
behavior, but in the future we should settle on a single ID location.
Since outputs and local nodes are always evaluated, if the reference a
resource form the configuration that isn't in the state, the
interpolation could fail.
Prune any local or output values that have no references in the graph.
Now that outputs are always evaluated, we still need a way to remove
them from state when they are destroyed.
Previously, outputs were removed during destroy from the same
"Applyable" node type that evaluates them. Now that we need to possibly
both evaluate and remove output during an apply, we add a new node -
NodeDestroyableOutput.
This new node is added to the graph by the DestroyOutputTransformer,
which make the new destroy node depend on all descendants of the output
node. This ensures that the output remains in the state as long as
everything which may interpolate the output still exists.
Always evaluate outputs during destroy, just like we did for locals.
This breaks existing tests, which we will handle separately.
Don't reverse output/local node evaluation order during destroy, as they
are both being evaluated.
Add a complex destroy provisioner testcase using locals, outputs and
variables.
Add that pesky "id" attribute to the instance states for interpolation.
Destroy-time provisioners require us to re-evaluate during destroy.
Rather than destroying local values, which doesn't do much since they
aren't persisted to state, we always evaluate them regardless of the
type of apply. Since the destroy-time local node is no longer a
"destroy" operation, the order of evaluation need to be reversed. Take
the existing DestroyValueReferenceTransformer and change it to reverse
the outgoing edges, rather than in incoming edges. This makes it so that
any dependencies of a local or output node are destroyed after
evaluation.
Having locals evaluated during destroy failed one other test, but that
was the odd case where we need `id` to exist as an attribute as well as
a field.
Extend the discovery timeout from 4 seconds to 11 seconds. This gives a
little more time for a slow host to response. The duration of 11s
keeps the delay reasonable, and puts it just after the default TLS
handshake timeout of 10s for easier differentiation of the error cases.
