Dose nginx support -HUP in single process mode? (Bug)

Server NGINX
1

Hi all,

dose nginx support -HUP to reload configure in single process mode?

It seems that it does support in the code:
‘src/os/unix/ngx_process.c:ngx_signal_handler()’.

However I think there is a bug when kill HUP to nginx in single process.
we can show it like:

add master_process off in configure file;
run nginx;
kill -HUP cat logs/nginx.log;
kill -HUP cat logs/nginx.log; (yes, we kill HUP twice)

then wait for about half of minite, the nignx will core!

Nginx aborts at ‘src/core/ngx_cycle.c:ngx_clean_old_cycles(): if
(cycle[i]->connections[n].fd != (ngx_socket_t) -1)’, where
cycle[i].connections is NULL.
The reason maybe nginx creates new cycle in ngx_init_cycle(), but didn’t
call the ngx_event_process_init() to init the connections.

Regards,
Wu

Working without master process is intended for development only
and doesn’t support configuration reloading.
