Help! log phase is not executed due to r->count being non-zero

October 11, 2014 12:28AM
Hey all,

I'm writing an authentication module that is structurally very similar to ngx_http_auth_request_module (https://github.com/PiotrSikora/ngx_http_auth_request_module/blob/master/ngx_http_auth_request_module.c). It basically sends a subrequest to a service for auth. For testing, I put a hello_world module module (https://github.com/perusio/nginx-hello-world-module/blob/master/ngx_http_hello_world_module.c) behind it like:

location /hello_world {
auth_request /auth;
hello_world;
hello_world_string "Hello World!";
}

Everything works fine EXCEPT I found today that the log phase is not excuted. I traced it down to ngx_http_close_request function in ngx_http_request.c (as it calls ngx_http_free_request(r, rc); to excute log handlers) where I found r->count = 2 so after r->count--; it's still non-zero thus ngx_http_close_request simply returns. I did not touch request count in my code.

Are we supposed to handle r->acount (either directly or through ngx_http_finalize_request) when using subrequest? I didn't see the original ngx_http_auth_request_module does so. If not, then why the request count is incorrect?

Thanks,
W
