==============================================
|
|
|
|
|
|
Sometimes, debugging or testing the dirstate requires making sure that we have
|
|
|
done a complete rewrite of the data file and have no unreachable data around,
|
|
|
sometimes it requires we ensure we don't.
|
|
|
|
|
|
We test the option to force this rewrite by creating the situation where an
|
|
|
append would happen and check that it doesn't happen.
