The part I left off was I'm on Ubuntu 18.04. I found this:

https://mariadb.com/kb/en/library/xtradbinnodb-storage-formats/

"Until MariaDB 10.2.1, the default was compact. Since MariaDB 10.2.2, the default is dynamic."

So I just used the MariaDB packages to go to 10.2 (which I think will match what we have on RHEL in production). That goes with the dynamic row format by default, and then everything worked without me changing a config file for MariaDB, or inserting dynamic on to the end off all of the create statements.

ROW_FORMAT=DYNAMIC fixed it for me, but you also need to make sure that the database parameter innodb_file_format is set to Barracuda. I think that requires a database restart.

From my reading, it does sound like that is the fix. It's an issue specific to InnoDB plus COMPACT or REDUNDANT row format. The limit for utf8mb4 would be 191 bytes, so there will probably be a lot more errors like that.  -Chad

How does one get Grouper 2.4 to work with MariaDB 10.1? I'm running into
the "Index column size too large. The maximum column size is 767 bytes."
error. Using utf8mb4.

I'm following the instructions from here:
https://spaces.at.internet2.edu/display/Grouper/Grouper+book+-+Setting+up+the+repository+database

I'm using the org.hibernate.dialect.MariaDB10Dialect dialect in
grouper.hibernate.properties.

I haven't gone through and fully inspected the generated file, but this
is generating the first error:


CREATE TABLE grouper_members
(
     id VARCHAR(40) NOT NULL,
     subject_id VARCHAR(255) NOT NULL,
     subject_source VARCHAR(255) NOT NULL,
     subject_type VARCHAR(255) NOT NULL,
     hibernate_version_number BIGINT,
     subject_identifier0 VARCHAR(255) NULL,
     sort_string0 VARCHAR(50) NULL,
     sort_string1 VARCHAR(50) NULL,
     sort_string2 VARCHAR(50) NULL,
     sort_string3 VARCHAR(50) NULL,
     sort_string4 VARCHAR(50) NULL,
     search_string0 VARCHAR(2048) NULL,
     search_string1 VARCHAR(2048) NULL,
     search_string2 VARCHAR(2048) NULL,
     search_string3 VARCHAR(2048) NULL,
     search_string4 VARCHAR(2048) NULL,
     name VARCHAR(2048) NULL,
     description VARCHAR(2048) NULL,
     context_id VARCHAR(40) NULL,
     PRIMARY KEY (id)
);

CREATE UNIQUE INDEX member_subjectsourcetype_idx ON grouper_members
(subject_id, subject_source, subject_type);

Is there a setting I need? I think adding ROW_FORMAT=DYNAMIC should fix
it, but wondering if there is an easier way. Or do I need a newer
MariaDB? Or should I be opening an issue?

Thanks,

Richard
