InnoDB: Failing assertion: bpage->buf_fix_count == 0 in buf_relocate

    XMLWordPrintable

    Details

      Description

      If the problem is indeed specific to innodb_background_scrub_data_compressed, I suppose it won't be fixed, since the variable is already deprecated and has no effect in 10.5. However, in any case I need to have it filed, so that the tests could start ignoring it. Feel free to close as "Won't fix" then.

      Despite being simple, the test case is non-deterministic. The probability of the failure seems to depend highly on the machine (build? compiler? filesystem?).
      A machine where it is decently reproducible will be provided.
      It also appears that creating an rr profile is impossible. While without rr on a suitable machine/build the failure happens on average within 5-10 attempts, with rr even hundreds of iterations haven't triggered it even once.

      # Run with
      # --mysqld=--innodb-encrypt-tables --mysqld=--innodb-encryption-threads=4  --mysqld=--file-key-management-filename=`pwd`/std_data/keys.txt --mysqld=--plugin-load-add=file_key_management  --repeat=100
       
      --source include/have_innodb.inc
       
      SET GLOBAL innodb_background_scrub_data_compressed= 1;
      CREATE TABLE t1 (a BLOB) ENGINE=InnoDB ROW_FORMAT=COMPRESSED;
       
      # Cleanup
      DROP TABLE t1;
      SET GLOBAL innodb_background_scrub_data_compressed= DEFAULT;
      

      Note the MTR options:

      --mysqld=--innodb-encrypt-tables --mysqld=--innodb-encryption-threads=4  --mysqld=--file-key-management-filename=`pwd`/std_data/keys.txt --mysqld=--plugin-load-add=file_key_management  --repeat=100

      Reproducible on 10.2-10.4. Not reproducible on 10.5.

      I had it happen at least once on a non-debug build as well, although I can't reproduce it on a non-debug build anymore. Below is a record of the occurrence (note Server version: 10.2.34-MariaDB-log).

      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.

      Hope that's ok; if not, decrease some variables in the equation.
