Hoi,
thanks for pointing the build failure out, Im trying to reproduce it locally but fail so far to see the problem :-S rebased on the latest master, when the two selftests added with the patches are run selecively, they pass: #> oe-selftest -r imagefeatures.ImageFeatures.test_image_gen_pkgdbfs imagefeatures.ImageFeatures.test_image_use_pkgdbfs but running the whole test-routine, same way the buildserver does in that log, currently fails me for other reasons (lack of resources? or i might be calling it the wrong way) any hints/ideas/pointers would be appreciated :-) gruß Johannes ________________________________________ From: Alexandre Belloni <[email protected]> Sent: Saturday, March 23, 2024 14:40 To: SCHNEIDER Johannes Cc: [email protected]; [email protected] Subject: Re: [OE-core] [PATCH v4 0/3] pkg-database and systemd-sysext image [You don't often get email from [email protected].
