Pull request overview
Adjusts values-file loading behavior used by helm lint -f (and other commands using values.Options) to improve error handling when local value files can’t be read, in response to issue #7985.
Changes:
- Wrap local
os.ReadFilefailures with a contextual error message (failed to read file ...). - Adds a new
pkg/cli/values/options.go.origfile containing a full copy of the pre-change implementation.
