Blueprints are not properly shared #3

Closed KubaP closed 3 years ago

KubaP commented 3 years ago

Expected result

When sharing blueprints with a profile, the blueprint-storage.dat file should remain linked.

Actual result

If factorio modifies (writes to?) the blueprint storage, it seems to replace the .symlink with an owned file .dat file, effectively breaking the sharing of the blueprints.

Possible solution

Rather than creating a symbolic link for the blueprint data file, create a hard link instead. This however will bring in a few limitations, see Hard Links and Junctions. The main one being that hard links cannot span multiple volumes, which means it may be necessary to force all profile folders to be located together, and only give the option to move the entire module appdata folder instead.

KubaP commented 3 years ago

It seems that hard links cannot bypass this; factorio must be just straight up deleting the blueprint-storage.dat file and writing a brand new one from memory to disk. The only way to therefore share blueprints seems to be to require a separate cmdlet which will manually copy the file to all places it is shared at.
