This adds more cruft to diff --git header to record the blob SHA1 and
the mode the patch/diff is intended to be applied against, to help the
receiving end fall back on a three-way merge. The new header looks
like this:
diff --git a/apply.c b/apply.c
index 7be5041..8366082 100644
--- a/apply.c
+++ b/apply.c
@@ -14,6 +14,7 @@
// files that are being modified, but doesn't apply the patch
// --stat does just a diffstat, and doesn't actually apply
+// --show-index-info shows the old and new index info for...
...
Upon receiving such a patch, if the patch did not apply cleanly to the
target tree, the recipient can try to find the matching old objects in
her object database and create a temporary tree, apply the patch to
that temporary tree, and attempt a 3-way merge between the patched
temporary tree and the target tree using the original temporary tree
as the common ancestor.
The patch lifts the code to compute the hash for an on-filesystem
object from update-index.c and makes it available to the diff output
routine.

test_description='More rename detection tests.
|
|
|
|
The rename detection logic should be able to detect pure rename or
|
|
copy of symbolic links, but should not produce rename/copy followed
|
|
by an edit for them.
