Document parameters in a single markdown file [#8] 
I was unhappy with the comments-in-yaml approach; it required
duplicating a lot of information and it was hard to find a balance
between "usefully thorough" and "readably concise.""

Log debug output in helm.Config [#9] 
Redacting KubeToken may not be sufficient, since it's possible that
someone would put secrets in Values or StringValues. Unilaterally
redacting those seems unhelpful, though, since they may be the very
thing the user is trying to debug. I've settled on redacting the obvious
field without trying to promise that all sensitive data will be hidden.

Allow a configurable env var prefix [#19] 
I'd like to keep Prefix's scope fairly limited, because it has potential
to spiral into something magnificently complex. You get one prefix
setting, it goes in `settings` not `environment`, end of feature.

Require no-error in config tests [#9] 2019-12-23 15:52:01 -08:00
Erin Call e2f53f3b08
Process non-prefixed forms of all config settings [#9] 
Trying to guess in advance which part of the config a user will put in
the `settings` section and which they'll put in `environment` is a
fool's errand. Just let everything go in either place.

The ServiceAccount field only had an `envconfig` tag (as opposed to
`split_words`) because that triggered envconfig to look for the non-
prefixed form. Now that we're finding non-prefixed forms of everything,
we can use the clearer/more concise tag.

Note that TestPopulateWithConflictingVariables isn't meant to say
"here's what behavior we *want*" so much as "here's what the behavior
*is*." I don't think one thing is any better than the other, but we
should know which one we're getting.

Use a plain string for helm.Config.Command [#9] 
I'm leaving the no-op test file in place because my next step is to add
new behavior that will require testing.

Don't document the kube_config setting [#8] 
See #30--there's no known use-case and no drone-helm users are using the
setting, so it's on the chopping block.

Prod maintainers to keep the docs and code in sync [#8] 
Offhand I don't see a way to ensure it programmatically, but I feel like
I should at least make an attempt.

Namespace is relevant in helm lint [#8] 
...Or at least, the namespace is passed around in helm's linting code. I
haven't proven that there's a case where omitting the namespace can
cause a linting problem, but I've seen enough to go ahead and document
the setting.

Rename "delete" to "uninstall" [#8] 
Helm 3 renamed the command, and I didn't realize it until just now.

See also 161960e, where it was renamed in the code.

Rename Delete to Uninstall [#4] 
Helm3 renamed its delete command to uninstall. We should still accept
helm_command=delete for drone-helm compatibility, but the internals
should use Helm's preferred name.

Format the Delete struct less weirdly [#4] 
I thought it was a golang style convention to put a blank line between
public and private struct fields, but apparently I imagined that.

Erin Call b93917c857
Use better expectations in lint_test [#3] 
The tests need to allow calls to Stdout/Stderr so they don't get
"Unexpected call" errors from gomock, but these tests aren't meant to
assert that the calls actually happened. Using .AnyTimes allows 0 or
more calls.

Extract Plan's InitKube creation [#4] 
It's `func initKube` rather than `var initKube = func` because initKube
is not meant to be returned by determineSteps.

Instantiate a Delete when appropriate [#4]

Add the --namespace flag in Lint.Prepare [#3] 
I don't know whether this is necessary; I'm just following drone-helm's
lead. At worst, helm will accept the flag, so it's at least *safe* to
include.
