For example, when blocks_size == 1, the process is as follows: transmit_block (i=0) └─> recvr->add_block(..., done, ...) // Pass done └─> SenderQueue::add_block └─> _pending_closures.push(done) // done is saved get_batch() [another thread] └─> closure_pair.first->Run() //⚠️ done->Run() is called └─> brpc releases request and response transmit_block (i=1) [original thread continues] └─> request->blocks_size() //⚠️ request has already been released! At this point, a use-after-free issue occurs. TODO: We should consider refactoring this part because add_block may release the request. We should not access the request after calling add_block. ``` apache#50113
