@simbuerg Do you have an idea why a newer pygit2 version breaks the container tests?

[boehmseb]

Would be good to know indeed. We desperately need to upgrade to pygit2 1.7 with the tool-suite, both, for features (my whitespace fix) and for the python 10 support.

[boehmseb]

I'm not yet sure why it fails now but any reruns will fail because alpine:edge now ships python 10 which requires this PR so benchbuild can be installed 😅

[boehmseb]

After manually resolving mentioned problem with the alpine version I could not reproduce this issue. The integration tests pass on my machine.

Now it seems to work also in the CI, not sure what the issue was 😆

[boehmseb]

Now I'm confused. This should fail for the reasons I described above. And if you look at the logs, the integration test that builds the container (and subsequent tests) does indeed fail. It just seems that the error handling is good enough so that benchbuild doesn't die so the CI does not detect the fail 🙈

[vulder]

Hmm, maybe they reverted the python3.10 change? Or Fixed something else in alpine.
@simbuerg maybe we should add an unit/integrationtest run for python3.10, just to be sure?

[boehmseb]

No, the test does fail, the fail just isn't picked up by the CI because benchbuild does not crash.

[dependabot]

A newer version of pygit2 exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

[simbuerg]

Merged this, but a follow-up PR has to fix #468
