(ITS#4622) syncrepl operations incomplete when consumer restarted

Full_Name: Matthias Halbritter
Version: 2.3.17 & 2.3.24

Submission from: (NULL) (

Changes int the provider's database are not fully passed on to the consumer when
it is restarted. The consumer then has only processed the sync operations up to
the stopping of the consumer. After restarting the consumer it will show
REFRESH_DELETE in debug mode although not all changes had been passed on and
processed. The consumer should finish or at least restart the sync operations.
The least should be a warning that there have been some problems.

Behaviour is reproducible with OpenLDAP 2.3.17 and 2.3.24. Behaviour is
reproducible in syncrepl refreshOnly mode (consumer restart during refresh) and
in syncrepl refreshAndPersist mode (consumer restart during refresh, consumer
restart during sync operations).

See also: mailing list openldap-software entry titled "syncrepl refresh not
finished after consumer restart" from Wed July 19th 2006.

I could do with having to start syncrepl with databases on provider and consumer
that have to be synchronized when starting syncrepl (that's how it's always been
with slurpd). I cannot, however, find proper use for syncrepl when I cannot be
sure whether all changes are properly passed on and processed.
