 Check out of sync nodemap

 First copy old data on the side.
 
   $ mkdir ../tmp-copies
   $ cp .hg/store/00changelog-????????????????.nd .hg/store/00changelog.n ../tmp-copies
 
 Nodemap lagging behind

 make a new commit

   $ hg log -r "$NODE" -T '{rev}\n'

 changelog altered
 -----------------
 
 If the nodemap is not gated behind a requirements, an unaware client can alter
 the repository so the revlog used to generate the nodemap is not longer
 compatible with the persistent nodemap. We need to detect that.
 
   $ hg up "$NODE~5"
   0 files updated, 0 files merged, 4 files removed, 0 files unresolved
   $ echo bar > babar
   $ hg add babar
   $ hg ci -m 'babar'
   created new head
   $ OTHERNODE=`hg log -r tip -T '{node}\n'`
   $ hg log -r "$OTHERNODE" -T '{rev}\n'
   5004
 
   $ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup
 
 the nodemap should detect the changelog have been tampered with and recover.
