[FreeNX-kNX] RE: Nxserver --terminate problem and nxnode file is missing a line

[Jonathan Chen]

 A little bit more digging around (not expert bash programmer - FYI).  I
finally got the "bash -x" mode to work for nxnode and below is basically
result of the nxnode section.   I see no killing of the PID.

++ '[' -z /tmp/NX-jonachen ']'
+ echo 'NX> 1000 NXNODE - Version 1.4.0-03 OS (GPL)'
NX> 1000 NXNODE - Version 1.4.0-03 OS (GPL)
+ '[' --terminate '!=' --check -a --terminate '!=' --setkey ']'
+ read CMDLINE
+ CMDLINE=a=b&sessionid=4B231EA2EF30B960507DF2CF67E0375C
+ cmd_node_terminate
++ getparam_sessionid
+++ getparam sessionid
+++ stringinstring '&sessionid='
'a=b&sessionid=4B231EA2EF30B960507DF2CF67E0375C'
+++ return 0

+++ result=4B231EA2EF30B960507DF2CF67E0375C
+++ echo 4B231EA2EF30B960507DF2CF67E0375C

++ sessionid=4B231EA2EF30B960507DF2CF67E0375C
++ '[' -n 4B231EA2EF30B960507DF2CF67E0375C ']'
++ echo 4B231EA2EF30B960507DF2CF67E0375C
+ sessionid=4B231EA2EF30B960507DF2CF67E0375C
+ echo 'NX> 716 Terminating session 4B231EA2EF30B960507DF2CF67E0375C on user

NX> 716 Terminating session 4B231EA2EF30B960507DF2CF67E0375C on user

++ cd /tmp/NX-jonachen/.nx/
++ echo C-cde-dev-01-1000-4B231EA2EF30B960507DF2CF67E0375C
++ cut -d- -f3

NX> 1001 Bye.
NX> 999 Bye

I probably am missing something but I'm not sure why it would "return" a
failure when the particular directory in question should exist.   

node_terminate_session()
{
        [ -d "$USER_FAKE_HOME/.nx/C-$1/" ] || return
        AGENT_PID=$(cat $USER_FAKE_HOME/.nx/C-$1/pids/agent 2>/dev/null)
        if [ -n "$AGENT_PID" ]
        then
                kill $AGENT_PID 2>/dev/null
                if ! [ "$virtualdesktop" = "0" -a "$ENABLE_ROOTLESS_MODE" !=
"1" ]
                then
                        sleep 1
                        kill -9 $AGENT_PID 2>/dev/null
                fi
        fi
        # remove possible leftover display ...
        display=$(echo $1 | cut -d"-" -f2)
        rm -f /tmp/.X$display-lock
        rm -f /tmp/.X11-unix/X$display
        rm -f /tmp/.nX$display-lock

        # remove cookie
        $COMMAND_XAUTH -v source
$USER_FAKE_HOME/.nx/C-$sess_id/scripts/authority >/dev/null 2>&1
        # FIXME: What to do on errors ... ?
        # TODO: Add parsing of var ...
        #mv $USER_FAKE_HOME/.nx/C-$1/ $USER_FAKE_HOME/.nx/F-C-$1/
        rm -rf $USER_FAKE_HOME/.nx/C-$1/
}
