Since we will no longer be maintaining the poky combo-layer, we need to figure out how to proceed. 1. How can we include the bitbake, and meta-yocto commit ids? Richard generated a new sha1 for buildbot that combines oe-core, bitbake, meta-yocto. We could just concatenate the three hashes. 2. Should we preserve the historic data or re-generate it? 3. Also the performance scripting code is in need of refreshing.

Presumably this is because it doesn't know that the old poky data should be glued in front of the new oe-core data. The raw data is in git, eg https://git.yoctoproject.org/yocto-buildstats/log/?h=perf-debian12-vk/master/qemux86

So I had an extensive look at the last failures. Basically, the issue is the same oe-core commit has been built with different versions of bitbake. I believe this happens when on a given day, some commits are merged in bitbake repo but none is merged in oe-core. So the builds from the previous and next nights will both use the same oe-core sha1 as a reference, but the build meta-data will differ. That's why we do get: AssertionError: Data mismatch 8b582ef8dd0cef0192d4c0104bcd9b5d642d132c != 35a421cdcafb3595b9de5489ffdc567825400d26 We are checking that all measurements for a given oe-core version have the same meta-data. Here they do differ on the bitbake revision: 8b582ef8dd0cef0192d4c0104bcd9b5d642d132c on one side, 35a421cdcafb3595b9de5489ffdc567825400d26 on the other. Now what is the correct solution here? - completely ignore differences on bitbake and meta-yocto revisions? - for each oe-core commit, only consider buildperf measurements for the most recent bitbake and meta-yocto commits? - parse all oe-core/bitbake/meta-yocto combinations separately? I'm not really sure how we would handle that, reading the code I believe it's far from a straightforward change. I've been playing with the second solution here, and it looks like it works correctly locally. I'm not sure this is the best solution, but I send some patch to discuss this.
