Can Lupa be used to run untrusted lua code in python?

Let's say I create LuaRuntime with register_eval=False and an attribute_filter that prevents access to anything except a few python functions. Is it safe to assume that lua code won't be able to do os.system("rm -rf *") or something like that?

Run Lua script from Python

Suppose I have a Lua script that contains 2 functions. I would like to call each of these functions with some arguments from a Python script.

I have seen tutorials on how to embed Lua code in Python and vice versa using Lunatic Python, however, my Lua functions to be executed in the Python script are not static and subject to change.

Hence, I need some way of importing the functions from the .lua file or simply executing the .lua file from the Python script with some arguments and receive a return value.

Could someone point me in the right direction?

Would be much appreciated.

Python Lupa Package Linking to liblua5.3.so?

I am attempting to add load the socket library in a Lupa runtime.

I installed socket with Luarocks, so I needed to append the necessary paths.

>>> import lupa
>>> sys.setdlopenflags(orig_dlflags)
>>> lua = lupa.LuaRuntime()
>>> lua.execute("package.cpath = package.cpath .. ';/root/.luarocks/lib/lua/5.3/?.so;/usr/local/lib/lua/5.3/?.so;/usr/local/lib/lua/5.3/loadall.so;./?.so'")
>>> lua.execute("  package.path = package.path .. ';/root/.luarocks/share/lua/5.3/?.lua;/root/.luarocks/share/lua/5.3/?/init.lua;/usr/local/share/lua/5.3/?.lua;/usr/local/share/lua/5.3/?/init.lua;/usr/local/lib/lua/5.3/?.lua;/usr/local/lib/lua/5.3/?/init.lua;./?.lua;./?/init.lua'")
>>> lua.require("socket")
Traceback (most recent call last):

/usr/local/lib/lua/5.3/socket/core.so: undefined symbol: lua_rotate

A similar issue is mentioned here but the proposed solution does not seem to work for me (I am running Ubuntu):

Linker Error Lunatic Python lua.require('socket') -> undefined symbol: lua_getmetatable

From my understanding, there is a linking problem to liblua5.3.so?

Any help would be greatly appreciated.

Thanks, Alex

lunatic-python / lupa import issue on ubuntu

I tried installing Lua and the wrapper libraries for the same on my computer, but the execution fails in the following manner.

After installing Lua-5.1, torch7, lua ( lunatic-python) , lupa, python-lua

when i open the interpreter -

    >>  import lupa
    >>  Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/local/lib/python2.7/dist-packages/lupa-1.1-py2.7-             
      linux-x86_64.egg/lupa/__init__.py", line 31, in <module>
      from lupa._lupa import *
      ImportError: /usr/local/lib/python2.7/dist-packages/lupa-1.1-      py2.7-linux-x86_64.egg/lupa/_lupa.so: undefined symbol: lua_gettop

and for lua

    >>  import lua
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    ImportError: /usr/local/lib/python2.7/dist-packages/lua.so: undefined symbol: lua_gettop

The installation returned no errors, however I had installed Lua5.3 ( which i uninstalled earlier ) added sys path to the /usr/local/bin and lib folders but to no avail.

Can someone help me with this? I'm new to these libraries and languages. Config - 64bit, Ubuntu 14.04. Using python2.7 for this
