Re: Segfault in NGINX - testcase

March 20, 2010 04:43AM
Hello,

The root node of the nginx-rbtree is *always* NULL, because
"ngx_rbtree_insert()" provides that feature. Only if the rbtree
has 2 elements and you delete the root node, then "parent" of the
root-node points to the deleted element. Why not fixing it?

Thank you very much
Marcus


The corresponding code:

void ngx_rbtree_insert(ngx_thread_volatile ngx_rbtree_t *tree, ngx_rbtree_node_t *node)
{
[....]
if (*root == sentinel) {
node->parent = NULL;
node->left = sentinel;
node->right = sentinel;
ngx_rbt_black(node);
*root = node;
