Issue ID: 10212 Summary: read-only tools may use wrong meta page Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs@openldap.org Reporter: hyc@openldap.org Target Milestone: ---
On a quiescent database that's only used for read-only txns, the txnid won't be initialized so it remains set to zero. Then only meta page zero will get used, even if page one is newer. Thus all information retrieved will be stale by one txn.
