Issue ID: 10026
Summary: Refresh handling can skip entries (si_dirty not
managed properly)
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: overlays
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Take MPR plain syncrepl with 3+ providers.
When a provider's own syncrepl session transitions to persist and a it starts a
new parallel session towards another host, that session always has to start as
a refresh. If that refresh serves entries to us, our handling of si_dirty is
not consistent:
- if the existing persist session serves some of these entries to us, we can
"forget" to pass the others to a newly connected consumer
- same if the refresh is abandoned and we start refreshing from a different
provider that might be behind what we were being served (again our consumers
could suffer)
- if we restart, si_dirty is forgotten and our consumers suffer even worse
We might need to be told (at the beginning of the refresh?) what the end state
we're going for is, so we can keep si_dirty on until then. And somehow persist
that knowledge in the DB...
