The do_build recrdeptask dependencies are removed for a cleaner
dependency relationship. This, however, makes rm_work behave
differently than previous releases. Not all built recipes' ${WORKDIR}
are cleaned. This is because we use the 'depends' varflag to
specify some dependencies, and rm_work cannot handle such case.
e.g.
do_rootfs[depends] += " makedevs-native:do_populate_sysroot ..."
I really don't see an easy way to restore previous behavior, but
we can use `--runall build' to ensure all built recipes' ${WORKDIR}
are cleaned.
e.g.
bitbake core-image-minimal --runall build
It would be helpful to add such note in this bbclass, as people who
use rm_work might also want cleaning all workdirs.
The following testing is done to ensure that the extra tasks added by
specifying '--runall build' should be mostly do_build, do_rm_work_all
and do_rm_work.
'''
1. bitbake -g core-image-minimal && grep label task-depends.dot > current
2. bitbake -g core-image-minimal --runall build && grep label task-depends.dot
> runall-build
3. diff current runall-build | grep '^>' | grep -v do_rm_work_all | grep -v
do_build | grep -v do_rm_work
'''
In my testing, the output is empty, which demonstrates that all extra
tasks introduced by '--runall build' are these three tasks.
