             Summary: tabbing in subshell displays more than commands of the current subshell
                 Key: KARAF-3055
                 URL: https://issues.apache.org/jira/browse/KARAF-3055
             Project: Karaf
          Issue Type: Bug
          Components: karaf-shell
    Affects Versions: 3.0.1
            Reporter: Rebecca Chan
            Priority: Minor


According to subshell release note, if the complete mode is set to either 'FIRST' or 'SUBSHELL' and you type the TAB key when you are in a subshell, the completion will display only the commands of the current subshell.  

I have two subshells, auth and auth-ldap.  Each has different commands

auth:show
auth-ldap:update
auth-ldap:delete

When I am in subshell 'auth' and press tab, I expect to see only the 'show' command.   However, 'show', 'delete' and 'update' are displayed in the 'auth' subshell.

*CAUSE*
After looking into the source code of karaf 3.0.1, there is a bug in method 'complete' in 'org.apache.karaf.shell.console.completer.CommandsCompleter'.  If the key of a completer starts with the current subshell name, the completer will be added to the matching completer list.  For my case, the current subshell name 'auth' partially matches the keys, "auth-ldap:update" and "auth-ldap:delete" , of completers and incorrect commands,"update" and "delete" are displayed in "auth" subshell.
