A test in t7800 tries to make sure that when git-difftool runs an
external tool that fails, it stops looking at files. Our fake failing
tool prints the file name it was asked to diff before exiting non-zero,
and then we confirm the output contains only that file.
However, this subtly relies on our internal reuse_worktree_file().
Because we're diffing between branches, the command run by difftool
might see:
- the git-stored filename (e.g., "file"), if we decided that the
working tree contents were up-to-date with the object in the index
and HEAD, and we could reuse them
- a temporary filename (e.g. "/tmp/abc123_file") if we had to dump the
contents from the object database
If the latter case happens, then the test fails, because it's expecting
the string "file". I discovered this when debugging something unrelated
with reuse_worktree_file(). I _thought_ it should be able to be
triggered by a racy-git situation, but running:
./t7800-difftool.sh --stress --run=2,13
never seems to fail. However, by my reading of reuse_worktree_file(),
this would probably always fail under Cygwin, because it sets
NO_FAST_WORKING_DIRECTORY. At any rate, since reuse_worktree_file()
is meant to be an optimization that may or may not trigger, our test
should be robust either way.
Instead of checking the filename, let's just make sure we got a single
line of output (which would not be true if we continued after the first
failure).
