Nginx Timer is killing my request pool

February 21, 2015 03:56PM
Hi All.

I've created a function for adding my custom ngx_timer , but after 1st time
loop my r->pool is setting to NULL , also it sets NULL my
r->connection->log, and after second loop it throws exception on *ngx_palloc
*because my r->pool is NULL.
I can't find out why, here is my function

*void add_aling_event(ngx_event_t *e, ngx_http_request_t *r, void
(*handler), int timer)*
*{*
* if(e)*
* {*
* ngx_add_timer(e, timer);*
* return;*
* }*
* ngx_event_t *event=ngx_palloc(r->pool,sizeof(ngx_event_t));*
* memset(event,0,sizeof(ngx_event_t));*
* event->data=r;*
* event->handler=handler;*
* event->log=r->connection->log;*
* ngx_add_timer(event, timer);*
*}*

And I'm calling this function like this.

static ngx_int_t ngx_http_aling_handler(ngx_http_request_t *r)
{
........
........
add_aling_event(NULL, r, hack_func, 50);
return NGX_AGAIN;
}

void hack_func(ngx_event_t *e)
{
ngx_http_request_t *r = e->data;
........
........

switch(shmLen[1])
{
case 1: // adding chain
{
..........................
* ..........................*
};break;
case 2: // adding last chain
{
..........................
* ..........................*
};break;
default:
{
add_aling_event(e, r, hack_func, 50);
};break;
}
}

After 1 or 2 calls r->pool is sets to NULL .....

Please help me figure out this issue.
Maybe I'm doing something wrong.
I've did this code using example here

Thanks.
