MariaDB Server 10.0.28 and 10.1.19 merged code from Percona XtraDB that introduced support for compressed columns. Much but not all of this code was disabled by placing #ifdef HAVE_PERCONA_COMPRESSED_COLUMNS around it. Among the unused but not disabled code is code to access some new system tables related to compressed columns. The creation of these system tables SYS_ZIP_DICT and SYS_ZIP_DICT_COLS would cause a crash in --innodb-read-only mode when upgrading from an earlier version to 10.0.28 or 10.1.19. Let us remove all the dead code related to compressed columns. Users who already upgraded to 10.0.28 and 10.1.19 will have the two above mentioned empty tables in their InnoDB system tablespace. Subsequent versions of MariaDB Server will completely ignore those tables.
