util.startup: Fix exiting on pidfile trouble
prosody.shutdown() relies on prosody.main_thread, which has not been set
yet at this point.
Doing a clean shutdown might actually be harmful in case it tears down
things set up by the conflicting Prosody, such as the very pidfile we
were looking at.
Thanks again SigmaTel71 for noticing
-- Compatibility layer for bitwise operations
-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if _G.bit32 then
return _G.bit32;
end
do
-- Lua 5.3 and 5.4 would be able to use native infix operators
local ok, bitop = pcall(require, "prosody.util.bit53")
if ok then
return bitop;
end
end
error "No bit module found. See https://prosody.im/doc/depends#bitop";
