ServerError: error in error handling

[drkwv]

This code registers a node which upon destruction will cause "ServerError: error in error handling" error with no info about actual line and file where error had hapenned, so it could be hard to trace if you're an admin server with tons of mods installed.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_node(

    minetest.get_current_modname()..":servererror",
    {
        description = "ServerError Block",
        tiles       = { "default_nc_rb.png" },
        groups      = { oddly_breakable_by_hand = 3 },
        after_destruct =
            function(pos, oldnode)
                local a
                a["b"] = "c"
            end,
    }
)

Things can go even worse because in following case you might think that you have initialized the "a" variable (surprise surprise, you initialized "b")

                print(a,b) -- nil   table: 0xafb07b20
                a["b"] = "c"
            end,
    }
)

Registered an issue on the github, unsure that I made it properly though. https://github.com/minetest/minetest/issues/1423
