The upstream git repository of dynare uses Git LFS (for storing *.mat
files). What has changed is that in release 6.0, the .gitattributes
file at the root of the repository is now included in the source
tarball (due to a change of upstream build system). As a consequence,
when I imported the upstream source tarball with “gbp import-orig”,
those *.mat files were imported as LFS objects in our DoG repository on
salsa (curiously, “gbp clone” ignores .gitattributes by default, but
“gbp import-orig” seems to respect it).

So this is actually an unintended move.

I admit that the situation can be confusing for developers who clone
our repo with “gbp clone”. Nothing tells them that Git LFS is needed,
and it’s unclear where such information should be displayed.

So another possibility would be to revert that change, and go back to
using regular storage for *.mat files in our salsa repo (as was the
case in previous releases). I would need to somehow filter the
.gitattributes from the upstream source tarball.
