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 }

Helper functions to add a special configuration file

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

INSTOPSYSTEM=0

define the stop command

function stop_system() { # prevent reentry if [ $INSTOPSYSTEM == 1 ]; then return; fi INSTOPSYSTEM=1 if [ -f ${BUILDDIR}/.toasterui.pid ]; then kill $(< ${BUILDDIR}/.toasterui.pid ) 2>/dev/null 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 trap - SIGHUP #trap - SIGCHLD INSTOPSYSTEM=0 }

function notify_chldexit() { if [ $NOTOASTERUI == 0 ]; then check_pidbyfile ${BUILDDIR}/.toasterui.pid && return stop_system fi }

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

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. File locks show that the system is on." 2>&1 echo "If you see problems, stop and then start the system again." 2>&1 return 3 fi

Execute the commands
