[Devel] dbt_lib.c:dbt_db_del_table(): should we release the lock of _tbc->sem when break ?

[yanlin]

hi, all,

in function dbt_db_del_table() of module dbtext, should we do "lock_release(&_tbc->sem)" before "break" when
we found the cached table for delete? in tbl_cache_free(), "lock_get(&_tbc->sem)" would be called, deadlock then.

int dbt_db_del_table(dbt_cache_p _dc, str *_s)
{
	...
	while(_tbc)
	{
			...
			lock_get(&_tbc->sem);
			if(_tbc->dtp->name.len == _s->len 
				&& !strncasecmp(_tbc->dtp->name.s, _s->s, _s->len))
			{
				...

				//============> need 'lock_release(&_tbc->sem)' before break ?
				break;
			}
			lock_release(&_tbc->sem);  
			...
	}                       
	...
	tbl_cache_free(_tbc);   	
	...

}
