Now that "git diff" handles stdin and relative paths outside the working tree correctly, we can convert all instances of "diff -u" to "git diff". This commit is really the result of $ perl -pi.bak -e 's/diff -u/git diff/' $(git grep -l "diff -u" t/) Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net> (cherry picked from commit c699a40d68215c7e44a5b26117a35c8a56fbd387)

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.
