RE: Xavante

["Dave Nichols" <dave.nichols@...>]

I would like to help. How?

I've downloaded the Kelper project and that works OK (Lua 5.0).
But trying to run Xavante under 5.1 does not. It responds to the first
request from a browser but in so doing it removes itself from the _reading
list in copas and there is no code to put it back. I don't understand how
moving from 5.0 to 5.1 could have this effect.

I've had to add package.seeall to all the Xavante modules which worries me a
bit as I don't understand the new scoping rules associated with the 5.1
module function.

I've also had to tweak venv as it tries to set the global environment for
require, module and the standard loaders, which under 5.1 are C functions so
its not allowed (why?). I got round this by requiring compat-5.1 and
tweaking that to override the built-in C functions.

Also in venv, I had to tweak clonetable as it could not cope with table
loops. Here is the revised version:

--01/06/06 DCN Modified to handle arbitrary self references
local function clonetable (t,visited)
  visited = visited or {}
  if visited[t] then return visited[t] end
  local newt = {}
  visited[t] = newt
  for i, v in pairs(t) do
    if type(v) == "table" then
      newt[i] = clonetable (v, visited)
    else
      newt[i] = v
    end
  end
  return newt
end

The horse is alive and well, but grazing on Lua 5.0 pastures... :o)

We are in the process of converting both Copas and Xavante to Lua 5.1, and
you'd be welcome to help us if you wish.
