Adding timer in nginx.c main

Server NGINX
1

Hi,

I am adding a timer in nginx’s main loop…

if (counter == -1) {
    ngx_log_error(NGX_LOG_EMERG, cycle->log, 0, "counter is null

adding
imer");
/* Registring Timer */
ngx_ipc_event.data = &dumb;
ngx_ipc_event.handler = ngx_ipc_event_handler;
ngx_ipc_event.log = cycle->log;
if (!ngx_ipc_event.timer_set) {
ngx_log_error(NGX_LOG_EMERG, cycle->log, 0, “Addding
timer”);
ngx_add_timer(&ngx_ipc_event, 3000);
}
} else {
ngx_log_error(NGX_LOG_EMERG, cycle->log, 0, “Counter is not null
%d”,counter);
}

static void
ngx_ipc_event_handler(ngx_event_t *ev)
{
ngx_log_error(NGX_LOG_EMERG, ev->log, 0, “Invoked event
handler”);
}

My handler is not being triggered at all…Although i get following
logs
in error.log

2015/01/12 21:56:48 [emerg] 22399#0: counter is null adding imer
nginx: [emerg] counter is null adding imer

It looks like you are adding your timer to init cycle. This won’t
work as the init cycle is only used to read a configuration file,
and destroyed afterwards.

Hi Maxim,

I shifted the timer to ngx_epoll_module.c and called it from
ngx_epoll_init.

My handler is still not getting invoked…

What would be the right way of adding a timer ? Writing a new module all
together ?
