the code from frame 0 returns error like this:
20854 if (!*table)
|
20855 *table= innodb_find_table_for_vc(thd, index->table);
|
20856
|
20857 /* For purge thread, there is a possiblity that table could have
|
20858 dropped, corrupted or unaccessible. */
|
20859 if (!*table)
|
20860 return true;
|
but up in frame 1 it is handled like a memory error:
968 if (innobase_allocate_row_for_vcol(thd, index, &v_heap,
|
969 &mysql_table,
|
970 &record, &vcol_storage)) {
|
971 if (v_heap) mem_heap_free(v_heap);
|
972 *err = DB_OUT_OF_MEMORY;
|
973 goto func_exit;
|
974 }
|
Make proper error handling by allowing innobase_allocate_row_for_vcol() return dberr_t and handle it properly up the stack. This requires to refactor a row of functions which were not supposed to fail with error (?!).
Handle DB_OUT_OF_MEMORY in row_mysql_handle_errors().
