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
