This script can be run in two modes.

When used with "source", from a build directory,

it enables toaster event logging and starts the bitbake resident server.

use as: source toaster [start|stop] [noweb] [noui]

When it is called as a stand-alone script, it starts just the

web server, and the building shall be done through the web interface.

As script, it will not return to the command prompt. Stop with Ctrl-C.

Helper function to kill a background toaster development server

Helper functions to add a special configuration file

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

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 WEBSERVER=1 for param in $*; do case $param in noui ) NOTOASTERUI=1 ;; noweb ) WEBSERVER=0 ;; 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
