Hi All, I have a question related to the wl_client creation in the compositor. I followed these step like weston did:
1. create socketpair. 2. fork a process and close `socket[0]` in child, close `socket[1]` in in parent process. 3. set the `WAYLAND_SOCKET` to `socket[1]`. 4. exec the program. I found out if I do this directly both compositor and client will stuck in the eventloop. It seems the compositor is stuck in the `wl_display_flush_clients` and client is stuck in `wl_event_queue_dispatch` and internally stuck in the epoll. So I think both compositor and client were waiting each other for some update. Then I found out that I need to pack the code in a `wl_event_loop_idle_func_t` and add it to the event_loop. But I am couldn't figure out why did the compositor stuck in the first place and why did the wl_event_loop_add_idle helped. Thanks very much. SZ
