This delays the error exit from hold_lock_file_for_update() in update-index, so that "update-index --refresh" in a read-only repository can still report what paths are stat-dirty before exiting. Also it makes -q to squelch the error message. Signed-off-by: Junio C Hamano <redacted> --- builtin-update-index.c | 11 ++++++++++- 1 files changed, 10 insertions(+), 1 deletions(-)
