No the view was not left unchanged. If you did a full configure/make/make install, dbmail will automatically run any necessary schema migrations. You can tell be looking at the tables. You should have a dbmail_upgrade_steps table, and the dbmail_subjectfield view now also contains a sortfield field. > Also according RFC 5256: "If the associated RFC-822 > <http://tools.ietf.org/html/rfc822> header for a particular criterion is > absent, it is treated as the empty string.

That is why the sort-subject tests still fail. > But with PostgreSQL as backend db dbmail puts NULL strings always at the > end of the resulting set. > To fix this we may apply COALESCE function on sortfield: > _append_sort(value->order, "COALESCE(sortfield, '')", reverse); That is one way to do it, but DBMail should always insert an empty string for messages that don't have a subject header. > It helps to pass imaptest's sort-subject test a bit further. > > The only issue left is that PostgreSQL puts header string "_" before all > other non empty strings, whereas imaptest puts it at the end after all > headers in test. > I haven't found out how to fix this yet (maybe it's imaptest's issue). It looks like imaptest is at fault here. Doing a simple test with sort(1) confirms postgresql's behavior. $~> cat > /tmp/test.txt << EOF a_a a _ a a EOF $~> cat /tmp/test.txt|sort -f _ a a a a_a $~> But maybe such characters have to be treated differently for some reason. -- ________________________________________________________________ Paul J Stevens pjstevns @ gmail, twitter, skype, linkedin * Premium Hosting Services and Web Application Consultancy * www.nfg.nl/i...@nfg.nl/+31.85.877.99.97 ________________________________________________________________ _______________________________________________ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://mailman.fastxs.nl/cgi-bin/mailman/listinfo/dbmail-dev
