Method SetReadBufferBlockStatus

be/src/runtime/io/disk-file.h:441–450

Helper function to set the status of a memory block. Caller should hold the physical_file_lock_. If the caller holds the lock of the read buffer block, SetStatusLocked() will be called.

  // If the caller holds the lock of the read buffer block, SetStatusLocked() will be
  // called.
  void SetReadBufferBlockStatus(MemBlock* read_buffer_block, MemBlockStatus status,
      const boost::shared_lock<boost::shared_mutex>& file_lock,
      const std::unique_lock<SpinLock>* block_lock = nullptr) {
    DCheckMemBlock(file_lock, read_buffer_block);
    if (block_lock == nullptr) {
      read_buffer_block->SetStatus(status);
    } else {
      read_buffer_block->SetStatusLocked(*block_lock, status);
    }
  }
