Fault in BlockManager.py

[Along-whu]

def can_append(self, seq: Sequence) -> bool:
    if seq.num_tokens % self.block_size == 0:
        return len(self.free_block_ids) > 0
    return True

I think this is wrong in " if seq.num_tokens % self.block_size == 0:"

maybe it should be " if seq.num_tokens % self.block_size == 1:"
