Check if the process is finished, even if stdout/stderr are not closed.
Moreover, if the process was terminated by a signal, the return code is
set to WEECHAT_HOOK_PROCESS_ERROR.
Some commands like /upgrade sent by relay client can cause problems, because
they were executed immediately (while relay code is running). The /upgrade
command unloads all plugins, so the result is unpredictable (it can cause a
crash).
This commit adds a timer (1 millisecond) to delay the execution of command
after we go back in the WeeChat main loop.
Use in evaluated strings (for example in /eval or triggers):
- "${info:relay_client_count}": total number of relay clients (any status)
With a specific status:
- "${info:relay_client_count,connecting}"
- "${info:relay_client_count,waiting_auth}"
- "${info:relay_client_count,connected}"
- "${info:relay_client_count,auth_failed}"
- "${info:relay_client_count,disconnected}"
