The parameters innodb_file_format and innodb_large_prefix were overridden
in the Debian-distributed configuration files, because the default values
of these parameters between MariaDB 5.5 and MariaDB 10.2
did not make any sense.
To allow a more seamless upgrade from MariaDB 10.1 to later versions,
let InnoDB recognize the parameters innodb_file_format and
innodb_large_prefix and issue deprecation warnings for them if they
are specified. A deprecation period of only one major release
(one year between the MariaDB 10.2 and 10.3 releases) is insufficient
for these widely used parameters.
This MySQL 5.5 test innodb_zip.innodb_prefix_index_lifted
was renamed in MySQL 5.7. In
commit 2e814d4702
the test was inadvertently removed, instead of being renamed.
The absence of this test caused a regression in MariaDB 10.2:
MDEV-15257 Invalid CREATE INDEX fails to report error correctly
