[maemo-developers] [maemo-developers] Hints for using Valgrind tools in Scratchbox

[From: José Dapena Paz]

	Hi,

	Some hints for using valgrind tools in Scratchbox+Maemo.

	First, standard way to use valgrind and gdb. af-sb-init.sh supports
parameters for using these tools with a piece of software we want to
study:

	af-sb-init.sh start --valgrind=my_app
	af-sb-init.sh start --gdb=my_app

	Valgrind will store the results in /tmp/valgrind-my_app.log*. Gdb will
show its prompt on load of my_app. This way you can debug/valgrind the
program you want.

	An interesting example would be: "I want to valgrind my status bar
applet". And this is easy:
	af-sb-init.sh start --valgrind=maemo_af_desktop

	You'll get the results in /tmp/valgrind-maemo_af_desktop.log*

	If you want to run other valgrind tools, you would better use these
environment variables:
	* VALGRINDCMD: the command you want to run inside valgrind.
	* VALGRIND: the valgrind command and parameters.

	For example, if you want to run massif of maemo_af_desktop, you would
run:
	export VALGRINDCMD=maemo_af_desktop
	export VALGRIND="valgrind --tool=massif --num-callers=50
--trace-children=yes --depth=5 --format=html --log-file=/tmp/massif
--alloc-fn=g_malloc --alloc-fn=g_malloc0 --alloc-fn=g_realloc
--alloc-fn=g_slice_alloc --alloc-fn=g_try_malloc
--alloc-fn=g_slice_alloc0"
	af-sb-init.sh start
	... do your stuff ...
	af-sb-init.sh stop

	And you'll get your massif reports in /tmp (logs) and $PWD (html and
postscripts).
