📝 Walkthrough

Walkthrough

The composite action exports CONFIG_ENV_VARS and CONFIG_ENV_VARS_INIT_RANDOM into the Defang step and unsets each environment variable name listed in config-env-vars, config-vars-init-random, and dont_complain_on_empty immediately before running the Defang command.

Changes

Environment variable cleanup before command execution

Layer / File(s)	Summary
Unset inputs before command execution action.yaml	Exports CONFIG_ENV_VARS and CONFIG_ENV_VARS_INIT_RANDOM to the step environment and adds a pre-command loop in the "Defang ${{ inputs['command'] }}" step that unsets each variable named by config-env-vars and config-vars-init-random plus dont_complain_on_empty prior to executing the Defang CLI.

Poem

🐰 I hop through the script with a careful paw,
Unsetting names before Defang sees law.
Quiet the warnings, hush the alarm,
Environment tidy, free from harm,
Now the CLI runs serene and calm.

In `@action.yaml`:
- Around line 187-188: The unset invocation using the expanded inputs ('${{
inputs['config-env-vars'] }}' and '${{ inputs['config-vars-init-random'] }}') is
unsafe for newline-delimited values and will break if inputs contain embedded
newlines; replace the single unsafe unset call with a loop that iterates over
each variable name (split on newlines) and calls unset on each item individually
(e.g., read the inputs into lines and for each line run unset "$var"), ensuring
you still unset the literal dont_complain_on_empty as well; update the code
around the unset statement to perform per-line safe unsets for the two input
variables referenced.
