A minetest sandboxing library, offering a basic environment, utilities, normal sandbox and a "coroutine" sandbox
Everything is avaliable in the async environment except the coroutine sandbox (due to minetest limitations)
See api.md for documentation and definitions
See env_docs.md for documentation of the sandbox environment
Libox (optionally) requires insecure environment to weigh local variables and upvalues in the coroutine sandbox. Without this someone can overfill your memory with local variables/upvalues
the libox mod will expose debug.getlocal and debug.getupvalue to all mods
Also if you are using coroutine sandboxes, please use luaJIT (default) instead of PUC lua, as there are a lot of differences between them
- Somewhat fixes mesecons issue #516 by limiting based on time not instructions
- May introduce new bugs, only time can test that
- Some of the responsibility is also on the mods that use libox as well (such as not doing something dumb like calling functions straight from the environment), the purpose of libox should be to also handle some of the more common stuff
dbg - not actually used for debugging, just used to provide dbg.shorten_path, if unavaliable it will fallback to the copied implementation
