Make it easier for users to debug shell task failure by including some breadcrumbs in the emitted .run file that (hopefully) points to the .bb/.bbclass file where the shell function was defined. Unfortunately this won't work with functions with _append or _prepends, since BitBake wipes the filename/lineno information. This shouldn't be too hard to fix; for now, you'll just see comments like this for such functions: [YOCTO #7877] Signed-off-by: Chris Laplante <chris.laplante@agilent.com> --- lib/bb/data.py | 6 ++++++ 1 file changed, 6 insertions(+)
