Commit0cf73755(unpack-trees.c: assume submodules are clean during check-out) changed an argument to verify_absent from 'path' to 'ce', which is however shadowed by a local variable of the same name. The bug triggers if verify_absent is used on a tree entry, for which the index contains one or more subsequent directories of the same length. The affected subdirectories are removed from the index. The testcase included in this commit bisects to55218834(checkout: do not lose staged removal), which reveals the bug in this case, but is otherwise unrelated.

test_description='Two way merge with read-tree -m $H $M
|
|
|
|
This test tries two-way merge (aka fast forward with carry forward).
|
|
|
|
There is the head (called H) and another commit (called M), which is
|
|
simply ahead of H. The index and the work tree contains a state that
|
|
is derived from H, but may also have local changes. This test checks
|
|
all the combinations described in the two-tree merge "carry forward"
|
|
rules, found in <Documentation/git read-tree.txt>.
|
|
|
|
In the test, these paths are used:
|
|
bozbar - in H, stays in M, modified from bozbar to gnusto
|
|
frotz - not in H added in M
|
|
nitfol - in H, stays in M unmodified
|
|
rezrov - in H, deleted in M
|
|
yomin - not in H nor M

This is a sample file used in two-way fast forward merge

tests. Its second line ends with a magic word bozbar

which will be modified by the merged head to gnusto.

It has some extra lines so that external tools can

successfully merge independent changes made to later

lines (such as this one), avoiding line conflicts.
