These aim to allow hinting to Terraform about situations where it's not
able to automatically infer value sensitivity.
"nonsensitive" is for situations where Terraform's behavior is too
conservative, such as when a new value is derived from a sensitive value
in such a way that all of the sensitive content is removed.
"sensitive", on the other hand, is for situations where Terraform can't
otherwise infer that a value is sensitive. These situations should be
pretty rare in a module that's making effective use of sensitive input
variables and output values, but the documentation shows one example of
an uncommon situation where a more direct hint via this function would
be needed.
Both of these functions are aimed at only occasional use in unusual
situations. They are here for reasons of pragmatism, not because we
expect them to be used routinely or recommend their use.
Since this is still at an early phase and likely to change significantly
in future iterations, rather than attempting to guess on a suitable final
location for documenting the testing feature I've instead taken the
unusual approach of adding a new page that is explicitly about the
experiment. My expectation is that once we conclude the experiment we'll
replace this new page with a stub that just explains that there was once
an experiment and then links to whatever final feature unfolded from the
research.
The URL for this page is hard-coded into the warning message in the
"terraform test" command, so as we continue to evolve this feature in
future releases we'll need to update the callout note on the page about
which Terraform CLI version it's currently talking about, so users of
older versions can clearly see when they'd need to upgrade in order to
participate in a later incarnation of the experiment.
* Remove deprecation on undeclared variable
Remove deprecation and add docs specific to the behavior around
undeclared variable values
* Limit full warnings to 2 instances, then summary
This way, the third warning is a summary, rather than the fourth
warning being the summary
During the language/CLI docs reorg, we noticed several pages that were no longer
viable; some were redundant, some useless, and some just very obsolete.
Since we were trying to avoid breaking links at the time, we opted to remove
them from the navs and leave them as "ghost pages" — still accessible, but not
findable.
This commit finally cleans these ghosts up and updates any remaining links to
relevant modern pages. Bustin' makes me feel good. 👻🚫
