From 09dca40b332cf6c349bff409a9f993d04df35f12 Mon Sep 17 00:00:00 2001 From: Valentin Bartenev Date: Tue, 23 Oct 2012 14:36:18 +0000 Subject: [PATCH] ngx_http_keepalive_handler() is now trying to not keep c->buffer's memory for idle connections. This behaviour is consistent with the ngx_http_set_keepalive() function and it should decrease memory usage in some cases (especially if epoll/rtsig is used). --- src/http/ngx_http_request.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/src/http/ngx_http_request.c b/src/http/ngx_http_request.c index ec9d4a1c3..ef010ff57 100644 --- a/src/http/ngx_http_request.c +++ b/src/http/ngx_http_request.c @@ -2753,6 +2753,20 @@ ngx_http_keepalive_handler(ngx_event_t *rev) ngx_http_close_connection(c); } + /* + * Like ngx_http_set_keepalive() we are trying to not hold + * c->buffer's memory for a keepalive connection. + */ + + if (ngx_pfree(c->pool, b->start) == NGX_OK) { + + /* + * the special note that c->buffer's memory was freed + */ + + b->pos = NULL; + } + return; }
