From ec99c9a89a65749093e16aed37d393f646597b31 Mon Sep 17 00:00:00 2001 From: Tay Ray Chuan Date: Wed, 3 Aug 2011 19:54:03 +0800 Subject: http.c: fix an invalid free() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove a free() on the static buffer returned by sha1_file_name(). While we're at it, replace xmalloc() calls on the structs http_(object|pack)_request with xcalloc() so that pointers in the structs get initialized to NULL. That way, free()'s are safe - for example, a free() on the url string member when aborting. This fixes an invalid free().
