Advisory: possible data loss during data export: msg#00013

Subject: Advisory: possible data loss during data export
Hi,

much to my regret I have to report a serious problem with the data
export from RefDB when using the getref command. A bug in the
client/server protocol implemented in 0.9.6-pre2 and later, 0.9.6
(release), and 0.9.7-preX may cause the client/server dialog to hang
if the transmitted datasets have a particular size (between 4096 and
4100 bytes). This affects all output formats, but is most likely to
occur in risx output as this format is the most verbose. Most RIS
datasets are smaller than 4096 byte.

The symptoms are an "error" entry in the refdbd log and a misleading
"ok" message in the refdbc client instead of a command summary when
the refdbc:getref command finishes. When making backups, please always
use RIS/risx *and* SQL dumps to be on the safe side.

I've fixed the faulty code, but I'd like to take my time to review
similar sections in the source code as other commands may be affected
as well. I'll update the CVS repository frequently in the next days,
but I'll announce a new prerelease as soon as I feel I've caught all
related problems.

regards,
Markus
