When upgrading dependency hash, fpm does not rebuild

[certik]

When I upgrade the git hash of a dependency in fpm.toml, my current project does not rebuild, and consequently the new dependency is not used. Fpm must read the hash of the dependency into the model, and if it changes, it must rebuild.

[certik]

fpm clean
fpm run

Does NOT fix this issue. To fix it, you have to:

git clean -dfx
rm -rf build
fpm run

then it works.

This is a big bug that we have to fix soon.

Does fpm clean --all work?

fpm update --clean should be useful, but indeed this command doesn't seem entirely intuitive.

[certik]

I'll try. But that's just a workaround. Fpm I think has all the information that the hash changed and consequently the dependency now has to update.

[zoziha]

Is it possible to update the dependency tree directly by checking the timestamp of the last modification of the fpm.toml for the top-level project?

Seems that's what meson did?
