Sometimes, some of the data gets truncated upon save, if it exceeds the field size.
I found that if I changed the datatype of tcversions.steps from TEXT to LONGTEXT, the data is not truncated. But, I don't know how this change in the DB will affect Testlink functionality.
So, is it safe to change the datatype of tcversions.summary, steps and expected_results from TEXT to LONGTEXT for this purpose?
