1 Create a repo such that the changelog entry refers to a null manifest node:

     2 

     3   $ hg init a

     4   $ cd a

     5   $ hg log

     6   $ touch x

     7   $ hg add x

     8   $ hg commit -m "init"

     9   $ hg rm x

    10   $ hg commit -q --amend

    11 

    12   $ wc -c < .hg/store/00manifest.i

    13   0

    14 

    15 Make sure that the manifest can be read (and is empty):

    16 

    17   $ hg --config rhg.on-unsupported=abort files -r .

    20 Test a null changelog rev, too:

    21 

    22   $ hg --config rhg.on-unsupported=abort files -r 0000000000000000000000000000000000000000
