I did some work last year to fix some of the low hanging fruit (on a
case by case basis).
My methodology was to do two runs of bitbake -k world, then compare
the output. In case anyone is interested, I used the script below to
identify the problematic recipes. Last time I ran it was in November,
by which time the output had reduced to a list of 5-10 items most of
the time.
#!/bin/sh
#
# Quick and dirty script to determine which tasks fail in one world.log,
# where they succeeded in another. world.log should be generated with, e.g.
# $ bitbake -k world | tee world.log
#
# If there are too many failures, this script will take too long as grep -f
# is slooow.
if [ $# != 2 ]; then
echo "usage: $0 world.log.1 world.log.2"
exit 1
fi
tasks="do_setscene do_fetch do_distribute_sources do_unpack do_prepsources
do_patch do_configure do_qa_configure do_compile do_install
do_populate_sysroot do_package do_package_write_ipk
do_package_write do_package_stage do_package_stage_all do_build
do_qa_staging"
tmp1=`mktemp /tmp/world_regress.XXXXXX`
tmp2=`mktemp /tmp/world_regress.XXXXXX`
for task in $tasks; do
grep "task $task: Failed" $2 \
| sed -e 's/^.*NOTE: package //' \
-e 's/task \(.*\): Failed/\1/' \
> $tmp1
grep "task $task: Succeeded" $1 \
| sed -e 's/^.*NOTE: package //' \
-e 's/task \(.*\): Succeeded/\1/' \
> $tmp2
grep -f $tmp1 $tmp2 \
| sort -n
done
rm -f $tmp1 $tmp2
