Hi Alexis, Firstly, this looks very much improved, thanks. It is great to start to see some meaningful data from this.

Firstly, if I try "yocto_testresults_query.py regression-report 4.2_M1 4.2_M2" in an openembedded-core repository instead of poky, it breaks. That isn't surprising but we should either make it work or show a sensible error. I also took a look the report and wondered why the matching isn't quite right and why we have these "regressions". If we could remove that noise, I think we'd get down to the real issues. I ended up doing: resulttool report --commit 4d19594b8bdacde6d809d3f2a25cff7c5a42295e . > /tmp/repa resulttool report --commit 5e249ec855517765f4b99e8039cb888ffa09c211 . > /tmp/repb meld /tmp/rep* which was interesting as gave lots of warnings like: "Warning duplicate ptest result 'acl.test/cp.test' for qemuarm64" so it looks like we had a couple of different test runs for qemuarm64 ptests which is confusing your new code. I suspect this happened due to some autobuilder glitch during the release build which restarted some of the build pieces. Not sure how to handle that yet, I'll give it some further thought but I wanted to share what I think is the source of some of the issues. Basically we need to get the regression report looking more like that meld output! Cheers, Richard
