Hello, during my work on the memory allocation topic I think I found a bug in the module (xhttp_prom) in the file (prom_metric.c) at line 823. There is an if else and in both parameters have the same code for shm_malloc() but in the else in the notes it reference for pkg_malloc but is also shm_malloc. If you also think its an error, I will fix it. //-----------------------------------------------------------------------------code /* Allocate space for str. */ if (shared_mem) { /* Shared memory */ /* We left space for zero at the end. */ lb_node->n.s = (char*)shm_malloc(len + 1); if (lb_node->n.s == NULL) { SHM_MEM_ERROR; goto error; } memcpy(lb_node->n.s, s, len); lb_node->n.len = len; } else { /* Pkg memory */ /* We left space for zero at the end. */ lb_node->n.s = (char*)shm_malloc(len + 1);//<--TODO--pantelis if (lb_node->n.s == NULL) { SHM_MEM_ERROR; goto error; } memcpy(lb_node->n.s, s, len); lb_node->n.len = len; } /* if shared_mem */ //------------------------------------------------------------------------------------------------------- Best Regard Pantelis Kolatsis
