* Add creation test and simplify in-place test
* Add deletion test
* Start adding marking from state
Start storing paths that should be marked
when pulled out of state. Implements deep
copy for attr paths. This commit also includes some
comment noise from investigations, and fixing the diff test
* Fix apply stripping marks
* Expand diff tests
* Basic apply test
* Update comments on equality checks to clarify current understanding
* Add JSON serialization for sensitive paths
We need to serialize a slice of cty.Path values to be used to re-mark
the sensitive values of a resource instance when loading the state file.
Paths consist of a list of steps, each of which may be either getting an
attribute value by name, or indexing into a collection by string or
number.
To serialize these without building a complex parser for a compact
string form, we render a nested array of small objects, like so:
[
[
{ type: "get_attr", value: "foo" },
{ type: "index", value: { "type": "number", "value": 2 } }
]
]
The above example is equivalent to a path `foo[2]`.
* Format diffs with map types
Comparisons need unmarked values to operate on,
so create unmarked values for those operations. Additionally,
change diff to cover map types
* Remove debugging printing
* Fix bug with marking non-sensitive values
When pulling a sensitive value from state,
we were previously using those marks to remark
the planned new value, but that new value
might *not* be sensitive, so let's not do that
* Fix apply test
Apply was not passing the second state
through to the third pass at apply
* Consistency in checking for length of paths vs inspecting into value
* In apply, don't mark with before paths
* AttrPaths test coverage for DeepCopy
* Revert format changes
Reverts format changes in format/diff for this
branch so those changes can be discussed on a separate PR
* Refactor name of AttrPaths to AttrSensitivePaths
* Rename AttributePaths/attributePaths for naming consistency

We need to be able to reference all possible dependencies for ordering
when the configuration is no longer present, which means that absolute
addresses must be used. Since this is only to recreate the proper
ordering for instance destruction, only resources addresses need to be
listed rather than individual instance addresses.
If an instance object in state has an earlier schema version number then
it is likely that the schema we're holding won't be able to decode the
raw data that is stored. Instead, we must ask the provider to upgrade it
for us first, which might also include translating it from flatmap form
if it was last updated with a Terraform version earlier than v0.12.
This ends up being a "seam" between our use of int64 for schema versions
in the providers package and uint64 everywhere else. We intend to
standardize on int64 everywhere eventually, but for now this remains
consistent with existing usage in each layer to keep the type conversion
noise contained here and avoid mass-updates to other Terraform components
at this time.
This also includes a minor change to the test helpers for the
backend/local package, which were inexplicably setting a SchemaVersion of
1 on the basic test state but setting the mock schema version to zero,
creating an invalid situation where the state would need to be downgraded.
We're going to allow the provider to encode whatever it wants in here, so
a provider can use whatever is most convenient for its implementation
language and to avoid some of the bugs we saw with the prior model where
the forced round-trip through JSON and back into interface{} would cause
some loss of fidelity, leading to bugs.
The types here were originally written to allow us to defer decoding of
object values until schemas are available, but it turns out that this was
forcing us to defer decoding longer than necessary and potentially decode
the same value multiple times.
To avoid this, we create pairs of types to represent the encoded and
decoded versions and methods for moving between them. These types are
identical to one another apart from how the dynamic values are
represented.
