Hi!
Lock manager has dev. build checkLength that asserts for lck_length <=
MAX_UCHAR.
Max identifier length is 63 characters, which may be multiplied by 4 in
utf8 bytes.
get_dsql_cache_item may create keys with 506 bytes.
lck_length is USHORT.
Is the assertion wrong or do we have bigger problem?
// Lock block
struct lbl
{
UCHAR lbl_type; // mem tag: type_lbl=in
use, type_null=free
UCHAR lbl_state; // High state granted
UCHAR lbl_size; // Key bytes allocated
UCHAR lbl_length; // Key bytes used
So, assertion is correct and we should have a problem with a long keys
BTW, long keys makes lookup operations more heavy, do we really need it ?
