Executing command, "mysqlbinlog --read-from-remote-server --host='xx.xx.xx.xx' --port=3306 --user=xxx --password=xxx --database=mysql --to-last-log mysql-bin.000001 --start-position=1098699 --stop-never |mysql -uxxx -pxxx", we found that last data read from remote couldn't commit. Write_on_release_cache(log_event.cc) function may have some problems.

In Write_on_release_cache(log_event.cc) function have following code:

public:

  enum flag

  {

    FLUSH_F

  };

...

  Write_on_release_cache(IO_CACHE *cache, FILE *file, flag_set flags = 0)

    : m_cache(cache), m_file(file), m_flags(flags)

  {

    reinit_io_cache(m_cache, WRITE_CACHE, 0L, FALSE, TRUE);

  }

  ~Write_on_release_cache()

  {

    copy_event_cache_to_file_and_reinit(m_cache, m_file);

    if (m_flags & FLUSH_F)

      fflush(m_file);

  }

...

The right code maybe:

public:

  enum flag

  {

    FLUSH_F = 1

  };

...
