Add a shutdown hook to verify that a context has been correctly
cancelled, so we can remove the sleep and stop guessing.
Add a plan version of the shutdown test as well.
There was no cancellation context for a plan, so it would always have to
run to completion as SIGINT was being swallowed.
Move the shutdown channel to the command Meta since it's used in
multiple commands.
A common pattern is to conditionally assign to "count"
in a resource in order to decide dynamically whether it
should be created. In that situation it's necessary to
refer to attributes of the resource using the splat
syntax, but historically we didn't show errors in output
expressions and so people "got away with" incorrect usage
in that context.
The intent of this warning is to catch
potentially-problematic usage of attributes on such
resources even if the count happens to be currently
set dynamically to 1, which would not generate the
error. Then the user can quickly locate and fix the
incorrect usage regardless of the current value.
Validation is the best time to return detailed diagnostics
to the user since we're much more likely to have source
location information, etc than we are in later operations.
This change doesn't actually add any detail to the messages
yet, but it changes the interface so that we can gradually
introduce more detailed diagnostics over time.
While here there are some minor adjustments to some of the
messages to improve their consistency with terminology we
use elsewhere.
StringMatch returns a validation function that can be used to match a
string against a regular expression. This can be used for simple
substring validations or more complex validation scenarios. Optionally,
an error message can be returned so that the user is returned a better
error message other than that their field did not match a regular
expression that they might not be able to understand.
The level of abstraction that needs the "svchost" is the Module, not the
FriendlyHost. Us the new method in the module package for registry
interaction.
The "not found" error should use the raw string directly from the config
source, but the existing method was adding the default registry if there
was no host indicated.
By wrapping the instruction portions in comments we can get a cleaner rendering of the issue if a user posts it without removing the instructions first.
The content is otherwise the same as before.
This is a genre of invalid output expression that we've seen quite
commonly while testing with 0.11.0-rc1, so we'll call it out specifically
in the upgrade guide and suggest how to fix it.
