Check whether size of generaldelta revlog is not bigger than its
|
|
|
regular equivalent. Test would fail if generaldelta was naive
|
|
|
implementation of parentdelta: third manifest revision would be fully
|
|
|
inserted due to big distance from its paren revision (zero).

Verify rev reordering doesnt create invalid bundles (issue4462)
|
|
|
This requires a commit tree that when pulled will reorder manifest revs such
|
|
|
that the second manifest to create a file rev will be ordered before the first
|
|
|
manifest to create that file rev. We also need to do a partial pull to ensure
|
|
|
reordering happens. At the end we verify the linkrev points at the earliest
|
|
|
commit.
