[Pkg-zfsonlinux-devel] Bug#1078427: zfs-linux: autopkgtest needs update for new version of linux-signed-amd64

[Paul Gevers]

Source: zfs-linux
Version: 2.2.4-2
Severity: serious
Tags: sid trixie
User: debian-ci at lists.debian.org
Usertags: needs-update
Control: affects -1 src:linux-signed-amd64 src:linux

Dear maintainer(s),

With a recent upload of linux-signed-amd64 the autopkgtest of zfs-linux 
fails in testing when that autopkgtest is run with the binary packages 
of linux-signed-amd64 from unstable. It passes when run with only 
packages from testing. In tabular form:

                        pass            fail
linux-signed-amd64     from testing    6.10.3+1
zfs-linux              from testing    2.2.4-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of 
linux-signed-amd64 to testing [1]. Of course, linux-signed-amd64 
shouldn't just break your autopkgtest (or even worse, your package), but 
linux is too much at the core of our distribution that we don't want to 
wait for updates of packages like this one that seem to break too easily 
by changes in linux. Is it possible to make the autopkgtest skip the 
test (restriction skipable with exit code 77) if a too new kernel is 
installed? Such that you can still see the difference between PASS and 
NEUTRAL for linux kernels and hence not blocking src:linux, while at the 
same time still have it failing on other regressions and thus blocking 
those from migrating? I think we can facilitate this better from ci.d.n 
side, by also exposing PASS-to-NEUTRAL changes (I think we don't do that 
currently) in the rss feed we provide if that would help you.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from linux-signed-amd64 should 
really add a versioned Breaks on the unfixed version of (one of your) 
package(s). Note: the Breaks is nice even if the issue is only in the 
autopkgtest as it helps the migration software to figure out the right 
versions to combine in the tests.
