Public bug reported:
bash completion, defined in /usr/share/bash-completion/completions/ufw,
doesn't work: the completion is not dynamically loaded, because it uses
deprecated helper function have().
According to /usr/share/bash-completions/bash_completion, which defines
the helper functions:
# Backwards compatibility for compat completions that use have().
# @deprecated should no longer be used; generally not needed with dynamically
# loaded completions, and _have is suitable for runtime use.
and at the end of the file:
unset -f have
unset have
which means: function have() is not available for usage. The bash
completion for ufw conditionally defines _ufw and the comspec:
have ufw &&
_ufw()
...
[ "$have" ] && complete -F _ufw ufw
These should be changed to:
_have ufw &&
_ufw()
...
_have ufw && complete -F _ufw ufw
