Steps to reproduce:
Attach files to bugzilla after upgrading from bugzilla 3.4 to bugzilla 5.0.
Investigation has shown that the first instance of this issue is for attach_id 46240.
select min(id) from bugs.attach_data where length(thedata) = 0;
I still have a copy of the bugs 3.4 database that was used to upgrade, and the last attachment in the old db (ie prior to upgrade) was 46225. Therefore it is only attachments added post upgrade that are having this issue.
Attachments are either not attached properly or are later removed (thedata set to null). It is unclear at this point if the attachment ever made it onto the system, but there have been no reports and no indication of errors when adding attachments, but have started getting reports of missing attachments when people are coming back to their bugs to view the attachments.
Attachment should be attached and remain attached and not be deleted (set to null).
I can't even find a way to delete attachments in bugzilla! I don't see a delete option anywhere.
