Hi,

This package fails to build a source package after a successful build
(dpkg-buildpackage ; dpkg-buildpackage -S).

This is probably a clear violation of Debian Policy section 4.9 (clean target),
but this is filed as severity:minor for now, because a discussion on
debian-devel showed that we might want to revisit the requirement of a working
'clean' target.

More information about this class of issues, included common problems and
solutions, is available at
https://wiki.debian.org/qa.debian.org/FTBFS/SourceAfterBuild

Relevant part of the build log:
The full build log is available from:
http://qa-logs.debian.net/2023/08/13/gem_0.94-8_unstable.log

If you reassign this bug to another package, please mark it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with mine
so that we can identify if something relevant changed in the meantime.

Greetings

https://bugs.debian.org/1044512

Hello.

I tried to reproduce this and it looked as fixed in trixie to me,
so I tried debbisect to determine the exact build-dependency which
fixed it.

However, debbisect (which internally uses snapshot.debian.org)
tells me that this issue did not even happen on 2023-08-13, the date
at which the bug was filed.

But there was something strange in the "successful" build log
for such date:

Could it be the case that the build leaves background processes
running which may or may not make a source build after a binary to
fail, in a randomly fashion?

Thanks.

Hi.

I still can't reproduce this in my rebuilding framework.

However, if I try to build the package directly from the git repository
(i.e. using dpkg-buildpackage, which may or may not work), then
I get this when trying to build the source package after
a successful binary build:

dh clean

So yes, this matches the commit which was made on 2024 to address the
issue, but paradoxically it's not what Lucas reported initially...

I feel that this bug is miscategorized and I don't know how
could we improve that.

IOhannes: Would you be willing to make an upload with the current
state of the package in salsa? (versioned 1:0.94-9, I guess).

Thanks.

sure.
