Primarily, before running the debuginfod-find tool, check that the debuginfod server has finished sweeping the deploy directory. If we make the request too soon then there's a rare chance that we run the client before it has scanned the right packages, and the log gets swamped with warnings from sqlite due to a race. Also: - unset DEBUGINFOD_URLS so the debuginfod doesn't proxy to an upstream server provided by the host distro - Lower concurrency to reduce system load and handle systems with lower maximum open file counts but lots of cores (as the concurrency means cores*2*2 open files) - Set the refresh times to 0 so we never rescan during the test - Only scan the packages for the format which the image is using - Log the commands that are being invoked (From OE-Core rev: d65729748253eaa640333198ca8aec05946cb9e8) Signed-off-by: Ross Burton <ross.burton@arm.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
