[Error] distrobox-based containerized application leaves behind temporary files

[mcepl]

Describe the bug

I am trying to use a distrobox-run container as an application, specifically my $EDITOR. Specifically, the project is hosted at https://build.opensuse.org/package/show/home:mcepl:moldavite/vis-master-container.

Everything works fine with slightly modified distrobox-export generated script, but when the editor leaves, there is sometime a temporary file left behind (..vis. pattern).

#!/bin/sh
# distrobox_binary
# name: vis
# outside of any container
if [ -z "${CONTAINER_ID}" ]; then
   exec /usr/bin/distrobox-enter  -n vis --  /usr/bin/vis  "$@"
# inside of the vis container
elif [ -x "/usr/bin/vis" ] ; then
    /usr/bin/vis "$@"
# inside of other container
elif [ -x "/usr/bin/distrobox-host-exec" ] ; then
    /usr/bin/distrobox-host-exec ~/.bin/vis "$@"
else
    echo "Cannot run vis"
    exit 255
fi

The only problem is that this editor leaves behind zero-length temporary files named .*.vis.* (e.g., ~/projekty/git-fixup/.git/.COMMIT_EDITMSG.vis.Hf71uh). I think those files I created at https://github.com/martanne/vis/blob/master/text-io.c#L253, and I wonder how it could clash with distrobox.

This change martanne/vis#507 looks a bit suspicious to me, but I wonder whether it is truly an error and whether distrobox shouldn’t accommodate it.

The problem doesn’t happen 100% (perhaps vis doesn’t create temporary files with small files?), so this log of distrobox-enter doesn’t show anything which I would consider wrong.

Desktop (please complete the following information):

• Are you using podman, docker or lilipod? podman
• Which version or podman, docker or lilipod? 5.2.5
• Which version of distrobox? 1.8.0
• Which host distribution? MicroOS (packages from openSUSE/Tumbleweed)
• How did you install distrobox? system packages

This is the output of one session where this creation of hidden files happened, but I don’t see anything interesting there.
