It's bad manners. Especially since there could be a signal during the call to unlink_or_warn(), in which case the signal handler will see the wrong filename and delete the reference file, leaving the lockfile behind. So make our own copy to work with. Signed-off-by: Michael Haggerty <redacted> --- refs.c | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-)
