oerdnj: Do the stretch builders also need to have libssl1.0-dev installed?

dbart Good catch, yes, the situation is same for stretch as for sid.

oerdnj: a status update for you:

After installing libssl1.0-dev, sid and stretch builders are now failing to build 10.1 because they don't have libssl-dev installed:

• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-sid-x86/builds/3675
• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-sid-amd64/builds/3608
• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-stretch-amd64/builds/836

Interestingly, 10.2 sid and stretch had been working:

• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-stretch-amd64/builds/829
• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-sid-amd64/builds/3582

But after the update to libssl1.0-dev, they started failing:

• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-stretch-amd64/builds/834
• http://buildbot.askmonty.org/buildbot/builders/kvm-deb-sid-amd64/builds/3604

So there's obviously some fix that has been made in 10.2 to get them to work with libssl-dev. It would probably be better to install libssl-dev back on them and backport the ssl fix from 10.2 to 10.1.

oerdnj: Any feedback on the above?

Also: Today I have updated our Stretch build/test VMs to the stable release. I'll circle back to them in a day or so to see if they are working properly and make corrections as necessary.

Ok, I'll hunt for the OpenSSL 1.1.0 fix in the git.

But to be honest I think the MariaDB should be able to build with both - 1.0 and 1.1. I'll look into that if I find some free time.

Totally agree that MariaDB should compile with either libssl 1.1 or 1.0.

serg or elenst: Do either of you remember who fixed the libssl issues in 10.2 for Sid and Stretch?

10.1 doesn't support OpenSSL 1.1 or LibreSSL.
10.2 supports OpenSSL 1.0.1 or above (incl. 1.1.0).
Would be good to know the exact OpenSSL versions of the packages.

Here are the versions currently in the stretch repositories:

Currently libssl1.0-dev is installed on the stretch builders. As I said in a previous comment: downgrading the builders from libssl-dev to libssl1.0-dev broke our MariaDB 10.2 builds. 10.1 builds, which were broken before making the change, are still broken, so the downgrade didn't help.

We need to have libssl-dev. OpenSSL 1.1. stretch is, perhaps, the only builder that can have it.

Ideally we should have both VMs, stretch+libssl-dev and stretch+libssl1.0-dev

As per serg's comment, I have installed libssl-dev on the stretch builders.

The sid VMs still have libssl1.0-dev installed.

great, thanks! it should be enough.
