I try to build solvespace for my own fork GitHub - nobodyinperson/solvespace: Parametric 2d/3d CAD with this solvespace.nix mostly copied from nixpkgs:

I build it like this:
nix-build -E 'with import <nixpkgs> {}; callPackage ./solvespace.nix {}'
# ...
# fatal: dumb http transport does not support shallow capabilities
# ...
# Failed to clone 'extlib/freetype' a second time, aborting
# ...
# [then sha256 mismatch]
… it seems to have a problem with the extlib/freetype submodule which seems to be hosted on a dumb git remote which doesn’t support shallow clones. But even with deepClone=true it works sometimes but not all the time stopped working a while ago as one constantly runs into hash mismatches. deepClone=true is also painfully slow.
The same happens for nixpkgs’ own solvespace btw:
# prefetch all dependencies for solvespace
nix-shell -p solvespace --run ''
# delete only the source archive
nix-store --delete "$(nix eval --impure --raw --expr '(let pkgs = import <nixpkgs> {}; in "${toString pkgs.solvespace.src}")')"
# then rebuild solvespace without the cache
nix-build --no-substitute -E 'with import <nixpkgs> {}; solvespace'
# ...
# fatal: dumb http transport does not support shallow capabilities
# ...
# Failed to clone 'extlib/freetype' a second time, aborting
# ...
# [then sha256 mismatch]
So apparently Hydra (or whatever builds cache.nixos.org) has some extra magic in place that manages to build the source archive including the submodules.
I’d like to see the Hydra logs for the source archive only, but I can’t find it. Here in the log for solvespace it just says that it fetches the source from the cache, wow that doesn’t help…
