From 4b9fa0e359a710b5d8dae542a92df7dbe56d9915 Mon Sep 17 00:00:00 2001 From: Tay Ray Chuan Date: Wed, 26 Aug 2009 20:20:53 +0800 Subject: [PATCH] http.c: set slot callback members to NULL when releasing object Set the members callback_func and callback_data of freq->slot to NULL when releasing a http_object_request. release_active_slot() is also invoked on the slot to remove the curl handle associated with the slot from the multi stack (CURLM *curlm in http.c). These prevent the callback function and data from being used in http methods (like http.c::finish_active_slot()) after a http_object_request has been free'd. Noticed by Ali Polatel, who later tested this patch to verify that it fixes the problem he saw; Dscho helped to identify the problem spot.
