| Summary | 0000816: Crash during compact_mapping() | ||||
| Description | LDMud crashed in svalue_cmp() during compact_mapping(), because the number of values in the hash part of the mapping was not correct. The happened, because resize_mapping (used for copy_mapping(), copy(), m_reallocate()) skipped keys referencing destructed objects, but did not correct the number of keys in the hash part, resulting in a hash part having less keys than stated in .hash.used. With the 'right' number of destructed keys and non-destructed keys, this led to the crash. (The bug was in the driver since 2007, so this situation seems to be rather rare in practice - however after 6 years MG crashed 2 times in 2 days because of this...) | ||||
| Steps To Reproduce | mapping m; void create() { if (clonep()) return; mapping m2 = ([clone_object(__FILE__): 1, clone_object(__FILE__) :2, 1:2, 2:3, 3:4, 4:5, 5:6, 6:7, 7:8, 8:9, 9:10, 10:11, 11:12, 12:13,13:14]); object* keys = m_indices(m2); filter(keys,#'objectp)->remove(); m=m_reallocate(m2,1); efun::garbage_collection("/log/gc"); } void remove() {destruct(this_object());} | ||||
