SubjectBug#1114938: dune-grid: FTBFS in bookworm: Test #8: subsamplingvtktest ....................................***Failed
Message-ID<LtWyB-eBfp-1@gated-at.bofh.it>
Package: src:dune-grid
Version: 2.9.0-2
Severity: serious
Control: fixed -1 2.10.0-1
Tags: ftbfs bookworm

Dear maintainer:

During a rebuild of all packages in bookworm, your package failed to build.

[ Note: The bug is marked as fixed with the version in trixie, but
  packages in bookworm must still build in bookworm ].

Below you will find how the build ends (probably the most relevant part,
but not necessarily). If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/bookworm/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:dune-grid, so that this is still
visible in the BTS web page for this package.

Thanks.

I think it all depends on much effort we[*] are willing to make.

At this point in the life of bookworm (which is 2/3 of its supported
period), there are already at least 60 different ftbfs bugs, so I
would say that fixing the FTBFS problem alone (disabling the offending
tests, if that's your plan and you know how to do it) would be more
than acceptable and a lot better than nothing.

[*] I say "we" because I'm also a team member, but I certainly can't
fix all the issues and I definitely appreciate any kind of QA work
that others might offer (like fixing ftbfs bugs in bookworm).

Thanks.

As the problem appears also when trying to view vtk files in paraview, I opted to fix this
in vtk. I did backport a fix that is already available in stable (to fix the same bug
1064762, see [1]) to bookworm. This fixes running the tests in dune-grid
and will prevent users of other packages experiencing problems when dealing with vtk files
containing raw data.

I am only a maintainer of dune-grid and cannot upload the fixed package myself. You will
find the fix in branch bookworm on salsa [2] (based on the latest bookworm release). I simply
cherry-picked the previous fix to bookworm.

For convenience the patch is also attached.

I am reassigning this to vtk

Best,

Markus

Control: -1 +patch -ftbfs
Control: -1 affects -1 src:dune-grid paraview

Removing the ftbfs as this is now assigned to vtk9 (that probably misses tests
checking parsing of vtk files with raw binary data).

Please not that it produces an ftbfs in dune-grid as that tests parsing of those
vtk files. It also affects the usage of paraview

Paraview uses an embedded copy of VTK during the build, so your patch
might not work as intended.

Source: vtk9
Followup-For: Bug #1114938
X-Debbugs-Cc: Debian Security Team <team@security.debian.org>

The issue with paraview's embedded copy of VTK is finally being
resolved with paraview 6 and vtk 9.5, though that won't help bookworm.

The patch being considered here for VTK looks more or less trivial,
meaning it should be simple enough to apply it to both vtk and
paraview in bookworm.

The upstream patch is
