We've missed a few recent additions to go.mod in the vendor directory. We
need to keep this updated for the moment until all of the surrounding
tooling is ready to go all-in with Go 1.11 modules.
We missed fixing this up during the big updates for the new plan/state
models since the failures were being masked by testBackendState being
broken.
This is the same sort of update made to many other tests: add schema to
the mock provider, adjust for the new plan/state types, and make
allowances for the new built-in diffing behavior in core.
The hashing function for cached backend configuration is different now, so
our hard-coded hash of the HTTP backend address wasn't working anymore.
Here we update the hash so that tests using this test backend will work
again. Rather than leaving it hard-coded, we'll instead compute it the
same way as "terraform init" would.
In practice only one test is actually using this function right now, so
we also update the test fixture for that test (TestPlan_outBackend) to
match the new expectations, though as of this commit it's still failing
with an unrelated error.
The mission of this process method used to include dealing with
auto-loaded tfvars files, but it doesn't do that anymore.
It does still deal with the -no-color option, but the test wasn't
exercising that part before.
Now the test here focuses on the -no-color behavior.
The process method still has a "vars" flag argument which is no longer
used. Since this is an unexported method we could potentially address this
but this commit is intentionally limited only to fixing the test.
Comments here indicate that this was erroneously returning an error but
we accepted it anyway to get the tests passing again after other work.
The tests over in the "terraform" package agree that cancelling should be
a successful outcome rather than an error.
I think that cancelling _should_ actually be an error, since Terraform did
not complete the operation it set out to complete, but that's a change
we'd need to make cautiously since automation wrapper scripts may be
depending on the success-on-cancel behavior.
Therefore this just fixes the command package test to agree with the
Terraform package tests and adds some FIXME notes to capture the potential
that we might want to update this later.
The State.Equal function is now more precise than this test needs. It's
only trying to distinguish between an empty state and a non-empty state,
so the string representation of state is good enough to get that done
while disregarding other subtle differences.
If the user uses the auto-expire value in the backend/swift settings
then swift will automatically delete their Statefile which is likely
something the user doesn't want given how Terraform works.
The "values" function wasn't producing consistently-ordered keys in its
result, leading to crashes. This fixes#19204.
While working on these functions anyway, this also improves slightly their
precision when working with object types, where we can produce a more
complete result for unknown values because the attribute names are part
of the type. We can also produce results for known maps that have unknown
elements; these unknowns will also appear in the values(...) result,
allowing them to propagate through expressions.
Finally, this adds a few more test cases to try different permutations
of empty and unknown values.
When the value we're looking in has an object type, we need to know the
key in order to decide the result type. Therefore an object lookup with
an unknown key must produce cty.DynamicVal, not an unknown value with a
known type.
The changelog is getting too long for convenient browsing and editing, so here we cut it off at the v0.9 series and link to the rest of the history via the v0.8.8 tag.
Since the state models can't preserve unknown values, we need to rely on the plan to persist these until the effective configuration can be fully resolved during the apply phase.
If plan and apply are both run against the same context then we still have
the planned output values in memory while we're doing the apply walk, so
we need to make sure to update them along with the state as we learn the
final known values of each output.
There were actually two different bugs here:
- We weren't removing any existing planned change for an output when
setting a new one. In retrospect a map would've been a better data
structure for the output changes, rather than a slice to mimic what we
do for resource instance objects, but for now we'll leave the structures
alone and clean up as needed. (The set of outputs should be small for
any reasonable configuration, so the main impact of this is some ugly
code in RemoveOutputChange.)
- RemoveOutputChange itself had a bug where it was iterating over the
resource changes rather than the output changes. This didn't matter
before because we weren't actually using that function, but now we are.
This fix is confirmed by restoring various existing context apply tests
back to passing again.
This new source type should be used for variables loaded from .tfvars files that were explicitly passed as command line arguments (e.g. -var-file=foo.tfvars)
Just as when we resolve single output values we must check to see if there
is a planned new value for an output before using the value in state,
because the planned new value might contain unknowns that can't be
represented directly in the state (and would thus be incorrectly returned
as null).
Booleans in the legacy form were stored as strings, and can appear as
the incorrect type in the new type system.
Unset fields in sets also might show up erroneously in diffs, with
equal old and new values.
