Travis will not, of course. But this feels like a bit of a micro-optimization. The test job is 3-4 minutes currently.

Keeping all 3 CI This depends on the number of cores you have on Travis CI.

I think the Docker route is the only way to minimize differences between the build systems. Best regards Heinrich ^ permalink raw reply [flat|nested] 5+ messages in thread

I would be quite open to moving this test to the rest of the QEMU based group, in GitLab as that might result in the overall run completing quicker. > > to reduce that, I think switching the test script to use $(nproc) rather > > than 4 for all make jobs would be a bit better.

I was under the impression that it would result in a fetch of the Docker image every time and thus probably take much longer overall and possibly require further splitting up of the Travis job. Honestly and off-topic for this particular thread, at this point I'd almost rather just drop Travis support and as much as I like the control we have in GitLab the fact that every runner has occasional bouts of random bad luck (DNS failures or jobs get stuck) means I wouldn't get overly upset if we just used Azure as it's still quicker than Travis, only a little slower than GitLab when it's fast and can be triggered by anyone. It would however require custodians to setup yet another account somewhere and that is a fairly big drawback (as I do expect custodians to CI their tree before sending a PR and in turn that blocking on the general Azure queue would be a big bottleneck I fear). -- Tom -------------- next part -------------- A non-text attachment was scrubbed...

So, I'm bringing this old patch up. Now that we have dropped Travis, GitLab and Azure use the same environment. Re-introducing this patch and a follow-up to modify the test script to use this prebuilt QEMU would be something we could do, at this point.
