- Detect if a table has field of type MYSQL_TYPE_VAR_STRING while running
"CHECK TABLE t FOR UPGRADE" and indicate it need to be fixed
with "REPAIR TABLE t".
- When running a "REPAIR TABLE t" or "ALTER TABLE t FORCE" on the above
table, install a special copy function to trim off the trailing spaces
which we safely can say that the pre 5.0 mysqld didn't put there.
mysql-test/r/varbinary.result:
Add test to see that a table with varbinary from 4.1 can be REPAIRED
mysql-test/t/varbinary.test:
Add test to see that a table with varbinary from 4.1 can be REPAIRED
sql/field_conv.cc:
Add new field copy function 'do_field_varbinary_pre50' used for copying
between MYSQL_TYPE_VAR_STRING and MYSQL_TYPE_VARCHAR. It will remove trailing
spaces from the field as MySQL <= 4.1 never stores the trailing spaces for
a MYSQL_TYPE_VAR_STRING.
Install this new copy function in ALTER TABLEs list of functions to use for
copying data during and alter if from field is a <= 4.1 varbinary and to
field is 5.0 varbinary.
sql/handler.cc:
If the table has a pre 5.0 varbinary, table not to be altered so the field
type is upgraded to 5.0 version and trailing space can be trimmed.
