Description:
I got an innodb table with 2 fields, one of them has a full-text index.
I got an error (180 Invalid InnoDB FTS Doc ID) while trying to update a row without changing the indexed field.

If I change the indexed field it works properly.

UPDATE foo SET fts_field='anychange' where id = 1;
# works ok

UPDATE foo SET no_fts_field='anychange' where id = 1;
# doesnt work
# 180 Invalid InnoDB FTS Doc ID 

UPDATE foo SET no_fts_field='anychange', fts_field='anychange' where id = 1;
# works ok

How to repeat:
install mysql-5.6.4-labs-innodb-fts-linux2.6-i686.tar.gz
in Ubuntu 11.04

create a simple foo table with two fields.
Create a full-text index in one field.

make some inserts.

try to update the non-index field without changing the indexed-field.

Suggested fix:
no idea

There is a bogus check on the hidden Doc ID value while this update does not need to update the Doc ID (no FTS indexed column affected). This is fixed.

The go around for now is to do a no-op update on the indexed FTS column so that to it qualifies the Doc ID change requirement.

This is fixed for the FTS release in 5.6.4

Fixed in 5.6.6
