From 8ed303c055ee003285231b6d781bfe2dd9c0d3d1 Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Mon, 9 Nov 2020 22:40:53 +0300 Subject: [PATCH] Request body: improved logging. Added logging before returning NGX_HTTP_INTERNAL_SERVER_ERROR if there are busy buffers after a request body flush. This should never happen with current code, though bugs can be introduced by 3rd party modules. Make sure debugging will be easy enough. --- src/http/ngx_http_request_body.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/http/ngx_http_request_body.c b/src/http/ngx_http_request_body.c index f3b938382..07e78d780 100644 --- a/src/http/ngx_http_request_body.c +++ b/src/http/ngx_http_request_body.c @@ -305,6 +305,9 @@ ngx_http_do_read_client_request_body(ngx_http_request_t *r) return NGX_AGAIN; } + ngx_log_error(NGX_LOG_ALERT, c->log, 0, + "busy buffers after request body flush"); + return NGX_HTTP_INTERNAL_SERVER_ERROR; }
