Yes git can report a longer string in case of collisions, but I don't expect to have one with 12 characters. This is mainly for some cases either people use full 40 chars or small ones. Indeed in background I am (and most probably Thomas too) fixing them while merging, I thought it is better idea to integrate that into script so that developers can be aware of the syntax issue and fix it before sending. > > >> Signed-off-by: Ferruh Yigit >> --- >> Cc: Qi Zhang >> --- >> devtools/check-git-log.sh | 5 +++++ >> 1 file changed, 5 insertions(+) >> >> diff --git a/devtools/check-git-log.sh b/devtools/check-git-log.sh >> index d39064f9d..f4d6c1fba 100755 >> --- a/devtools/check-git-log.sh >> +++ b/devtools/check-git-log.sh >> @@ -177,6 +177,11 @@ bad=$(for fixtag in $fixtags ; do >> done | sed 's,^,\t,') >> [ -z "$bad" ] || printf "Wrong 'Fixes' reference:\n$bad\n" >> >> +bad=$(for fixtag in $fixtags ; do >> > + echo $fixtag | awk '{print $2}' | awk 'length != 12 {print}' >> > +done) >> > > Not an awk expert (this could be done in pure shell, but this is a > different story :-p), but I would see something like: > > for fixtag in $fixtags; do > echo $fixtag | awk 'length($2) < 12 { print $2 }'; > done Yes, looks better, I will update the script. And no specific preference on shell or awk implementation, there is no performance concern in this script and awk already used by it, I am good as long as it is functional.
