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
|

|
|
|
|
|
|
$ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup
|
|
|
|
|
|
the nodemap should detect the changelog have been tampered with and recover.
