>Description:
The /etc/rc.subr script contains a function check_pidfile that calls _find_processes to check if a file containing a pid is referencing a running process matching a specific name.
It's due to /bin/sh 'case' struct.
Try:
#!/bin/sh
my="[tcp]"
case ${my} in
${my}) echo no;;
"${my}") echo yes;;
esac
In /etc/rc.subr:
_fp_match='case "$_arg0" in
$_procname|$_procnamebn|${_procnamebn}:|"(${_procnamebn})")'
BTW, i don't understand why both $_procnamebn and ${_procnamebn} are there...
>How-To-Repeat:
Try to manage with an rcNG script a daemon who display in ps in "[]", ie tcpserver:
21478 p0 I 0:00,00 [tcpserver]
check_pidfile ${pidfile} '[tcpserver]'
This call doesn't returns any result.
>Fix:
In /etc/rc.subr:
-_fp_match='case "$_arg0" in
$_procname|$_procnamebn|${_procnamebn}:|"(${_procnamebn})")'
+_fp_match='case "$_arg0" in
$_procname|"$_procnamebn"|${_procnamebn}:|"(${_procnamebn})")'
Or maybe...
+_fp_match='case "$_arg0" in
"$_procname"|"$_procnamebn"|"${_procnamebn}:"|"(${_procnamebn})")'
