Column message_body too short

[sebastianopilla]

Question/Issue Overview

Using MariaDB, Holdmail fails to insert a row in the message table if the length of the message body exceeds the limit of the text type (65KB).

Expected Behavior

The row corresponding to the message should be successfully inserted in the message table.

Current Behavior

The row is not inserted, and a SQLException similar to the following one is visible in the log:

May 21 15:25:22 dev-batches java[1378]: Caused by: java.sql.SQLException: Data too long for column 'message_body' at row 1
May 21 15:25:22 dev-batches java[1378]: Query is: insert into message (has_attachments, identifier, message_size, message_body, received_date,

Reproducible Sequence

1. Send a message larger than 65KB (for example with attachments).

Additional Information

A quick fix is to change the type of the message_body column to LONGTEXT:

MariaDB [holdmaildb]> alter table message modify message_body longtext;

MariaDB [holdmaildb]> desc message;

Thanks for the bug report!

I suspect this is somewhat related to #77 - if somebody picks this up, please consider also moving the message_body to its own table. The listing of messages does not need to query this attribute (IIRC)
