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

  $ echo bar2 > bar
  $ hg ci -m 'bar2'
  $ NODE=`hg log -r tip -T '{node}\n'`
  $ hg log -r "$NODE" -T '{rev}\n'
  5003

If the nodemap is lagging behind, it can catch up fine

  $ hg debugnodemap --metadata
  uid: ???????????????? (glob)

  $ 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.

removing data with rollback

  $ echo aso > a
  $ hg ci -m a4
  $ hg rollback
  repository tip rolled back to revision 5005 (undo commit)
  working directory now based on revision 5005
  $ hg id -r .

Persistent nodemap and local/streaming clone
============================================

  $ cd ..

standard clone
--------------

The persistent nodemap should exist after a streaming clone

  00changelog-*.nd (glob)
