Bug Description

[Impact]

Tab completion is currently broken.

[Test Case]

$ ufw <tab><tab>
allow delete --dry-run --help logging reset status
app deny enable insert reject route version
default disable --force limit reload show

With an unpatched ufw, tab completion only shows the files in the current directory, which is meaningless for ufw.

[Regression Potential]

Risk of regression is considered very low since tab completion is totally broken and correct functionality is easily tested.

= Original description =

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

Thank you for reporting this. I'll get it fixed in upstream ufw, Debian and Ubuntu 18.10. I'll then do an SRU for 18.04 LTS.

  * debian/ufw.maintscript: remove /etc/bash_completion.d/ufw on upgrade
    (LP: #1602834)
  * debian/control: remove no longer needed xs-python-version and
    x-python3-version fields
  * update debian/before6.rules.md5sum for file shipped in 0.35-6. While both
    before.rules and before6.rules were updated in this new upstream release,
    0.35-6 mistakenly already had its own md5sum for before.rules, so we don't
    need to add it now.

An upload of ufw to cosmic-proposed has been rejected from the upload queue for the following reason: "All bugs mentioned in the .changes file (so therefore also in the new debian/changelog entries) need to comply with SRU standards (test-case, regression potential). Please re-upload after filling out the required info or modify changelog to exclude irrelevant bug numbers.".
