[0.13.12] Factorio errors on game.write_file

[Afforess]

Bug: Factorio game.write_file('foo', 'bar') or any combination of API calls to game.write_file fails if the user has symlinked the script-output directory to another location. No mods are required to reproduce, console commands show the error as well.

Steps to reproduce:

1. Symlink (or Hardlink on Windows) factorio/script-output to another directory (say, /tmp)
2. Launch new Factorio map
3. In console, execute /c game.write_file('foo', 'bar')

Error:

Code: Select all

Cannot execute command. Error: [string "game.write_file('foo', 'bar')"]:1: Scripts can only use file space inside of /home/afforess/.factorio/script-output (requested path was /home/afforess/.factorio/script-output/foo)

Not sure what the best solution here is, but doing this generates a whole lot of errors when users try to run mods, and they blame it on mods, instead of themselves.

The solution: don't symlink script-output to a different folder.

The actual solution: we don't have one yet. The file system library we use doesn't work correctly with symlinks. It's a known issue.

I agree completely.

Yeah. I've got no easy answers either.

Tell them to use a bind mount instead.

This might be solved in 0.13.14. I know for sure it is solved on Windows ... don't know about other platforms.
Let us know, if it is still problem in 0.13.14

For Linux (in my case Arch Linux 64bi) the issue still exists in 14.22.

I can't reproduce this on my machine. Could you please post complete log file?
