I've noticed my bash autocomplete will frequently hang. System info: I'm running Ubuntu 14.04.1 Bash Autocomplete 2.1-4 Authentication using sssd configured for kerberos and ldap
Suspected Cause: in _quote_readline_by_ref() has a line elif [[ $1 == ~* ]]; then It appears this line causes sssd to make an ldap request for all the accounts which take a couple of seconds. I'm fairly certain this is the cause because if I delete that elif, the delay goes away and there are no ldap requests. Is this a bug or is it intended to retrieve all home directories? complete function # This function quotes the argument in a way so that readline dequoting # results in the original argument. This is necessary for at least # `compgen' which requires its arguments quoted/escaped: # # $ ls "a'b/" # c # $ compgen -f "a'b/" # Wrong, doesn't return output # $ compgen -f "a\'b/" # Good # a\'b/c # # See also: # - http://lists.gnu.org/archive/html/bug-bash/2009-03/msg00155.html # - http://www.mail-archive.com/bash-completion-devel@lists.alioth.\ # debian.org/msg01944.html # @param $1 Argument to quote # @param $2 Name of variable to return result to _quote_readline_by_ref() { if [ -z "$1" ]; then # avoid quoting if empty printf -v $2 %s "$1" elif [[ $1 == \'* ]]; then # Leave out first character printf -v $2 %s "${1:1}" elif [[ $1 == ~* ]]; then # avoid escaping first ~ printf -v $2 ~%q "${1:1}" else printf -v $2 %q "$1" fi # Replace double escaping ( \\ ) by single ( \ ) # This happens always when argument is already escaped at cmdline, # and passed to this function as e.g.: file\ with\ spaces [[ ${!2} == *\\* ]] && printf -v $2 %s "${1//\\\\/\\}" # If result becomes quoted like this: $'string', re-evaluate in order to # drop the additional quoting.
