This script enables toaster event logging and

starts bitbake resident server

use as: source toaster [start|stop]

Helper function to kill a background toaster development server

function webserverKillAll() { local pidfile for pidfile in ${BUILDDIR}/.toastermain.pid; do if [ -f ${pidfile} ]; then while kill -0 $(< ${pidfile}) 2>/dev/null; do kill -SIGTERM -$(< ${pidfile}) 2>/dev/null sleep 1; done; rm ${pidfile} fi done }

function webserverStartAll() { retval=0 python $BBBASEDIR/lib/toaster/manage.py syncdb || retval=1 python $BBBASEDIR/lib/toaster/manage.py migrate orm || retval=2 if [ $retval -eq 1 ]; then echo "Failed db sync, stopping system start" 1>&2 elif [ $retval -eq 2 ]; then echo -e "\nError on migration, trying to recover... \n" python $BBBASEDIR/lib/toaster/manage.py migrate orm 0001_initial --fake retval=0 python $BBBASEDIR/lib/toaster/manage.py migrate orm || retval=1 fi if [ $retval -eq 0 ]; then python $BBBASEDIR/lib/toaster/manage.py runserver 0.0.0.0:8000 </dev/null >{BUILDDIR}/toaster_web.log 2>&1 & echo ! >${BUILDDIR}/.toastermain.pid sleep 1 if ! cat "${BUILDDIR}/.toastermain.pid" | xargs -I{} kill -0 {} ; then retval=1 rm "${BUILDDIR}/.toastermain.pid" fi fi return $retval }

Helper functions to add a special configuration file

function addtoConfiguration() { echo "#Created by toaster start script" > ${BUILDDIR}/conf/$2 echo $1 >> ${BUILDDIR}/conf/$2 }

define the stop command

function stop_system() { if [ -f ${BUILDDIR}/.toasterui.pid ]; then kill $(< ${BUILDDIR}/.toasterui.pid ) rm ${BUILDDIR}/.toasterui.pid fi BBSERVER=localhost:8200 bitbake -m unset BBSERVER webserverKillAll # force stop any misbehaving bitbake server lsof bitbake.lock | awk '{print $2}' | grep "[0-9]+" | xargs -n1 -r kill }

We make sure we're running in the current shell and in a good environment

if [ -z "$ZSH_NAME" ] && [ basename \"$0\" = basename \"$BASH_SOURCE\" ]; then echo "Error: This script needs to be sourced. Please run as 'source toaster [start|stop]'" 1>&2; exit 1 fi

if [ -z "$BUILDDIR" ] || [ -z which bitbake ]; then echo "Error: Build environment is not setup or bitbake is not in path." 1>&2; return 2 fi

BBBASEDIR=dirname ${BASH_SOURCE}/..

Verify prerequisites

if ! echo "import django; print (1,5) == django.VERSION[0:2]" | python 2>/dev/null | grep True >/dev/null; then echo -e "This program needs Django 1.5. Please install with\n\nsudo pip install django==1.5" return 2 fi

if ! echo "import south; print [0,8,4] == map(int,south.version.split("."))" | python 2>/dev/null | grep True >/dev/null; then echo -e "This program needs South 0.8.4. Please install with\n\nsudo pip install south==0.8.4" return 2 fi

Determine the action. If specified by arguments, fine, if not, toggle it

if [ "x$1" == "xstart" ] || [ "x$1" == "xstop" ]; then CMD="$1" else if [ -z "$BBSERVER" ]; then CMD="start" else CMD="stop" fi; fi

NOTOASTERUI=0 for param in $*; do case $param in noui ) NOTOASTERUI=1 ;; esac done

echo "The system will $CMD."

Make sure it's safe to run by checking bitbake lock

lock=1 if [ -e $BUILDDIR/bitbake.lock ]; then (flock -n 200 ) 200<$BUILDDIR/bitbake.lock || lock=0 fi

if [ ${CMD} == "start" ] && ( [ $lock -eq 0 ] || [ -e $BUILDDIR/.toastermain.pid ] ); then echo "Error: bitbake lock state error. System is already on." 2>&1 return 3 elif [ ${CMD} == "stop" ] && ( [ $lock -eq 1 ] || ! [ -e $BUILDDIR/.toastermain.pid ] ) ; then echo "Error: bitbake lock state error. Trying to stop a stopped system ? If you think the system is hanged up, you can try to manually stop system with the commands

BBSERVER=localhost:8200 bitbake -m

and

webserverKillAll

" 2>&1 return 3 fi

Execute the commands
