Hi, Brian, list!
luaposix 5.1.2-1
lua-ev 1.1
OS X 10.6 and Ubuntu 9.10 x86_64
If I require lua-ev (nothing else needed), it breaks posix.fork():
child processes instantly die (they become zombies if you uncomment
the last line in the example). Please see below script to reproduce.
$ lua fork-ev.luanot requiring lua-ev
child pid is 28009
child is forked
$ lua fork-ev.lua --with-ev
requiring lua-ev
child pid is 28012
# note no "child is forked" message
Any clues?
Alexander.
--[[ fork-ev.lua ]]--
local use_ev = (select(1, ...) == "--with-ev")
pcall(require, 'luarocks.require')
local posix = require 'posix'
if use_ev then
print("requiring lua-ev")
local ev = require 'ev'
else
print("not requiring lua-ev")
end
local pid = posix.fork()
if pid == 0 then
print("child is forked")
else
print("child pid is", pid)
end
-- while true do end
