Server crashes on corrupted pages during DROP TABLE

    XMLWordPrintable

    Details

      Description

      In provided test we intentionally create several tables using page compression and corrupt

      • compression method field
      • payload size
      • actual payload data

      Expectation is naturally that server will not crash. This expectation is not true for all possible compression methods.

      2018-06-15 14:45:55 140214146956032 [ERROR] InnoDB: Unable to read tablespace 27 page no 3 into the buffer pool after 100 attempts. The most probable cause of this error may be that the table has been corrupted. You can try to fix this problem by using innodb_force_recovery. Please see http://dev.mysql.com/doc/refman/5.6/en/ for more details. Aborting...

      InnoDB: If you get repeated assertion failures or crashes, even

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
       
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed, 
      something is definitely wrong and this may fail.
       
      Server version: 10.1.34-MariaDB-debug
      key_buffer_size=1048576
      read_buffer_size=131072
      max_used_connections=1
      max_threads=153
      thread_count=1
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63026 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      Attempting backtrace. You can use the following information to find out
      where mysqld died. If you see no messages after this, something went
      terribly wrong...
