Hi Junio, Christian,
it's been a while.
I see that the work on trailers is going on.
I tried going over the documentation but I could not figure
out how would one implement multiple signatures using the
trailers mechanism.
As a reminder, this old patchset (that I replied to) enhanced git am -s
with an option to add different signatures depending on
the option passed to the -s flag.
E.g. I have
[am "a"]
signoff = "Acked-by: Michael S. Tsirkin <mst@xxxxxxxxxx>"
[am "r"]
signoff = "Reviewed-by: Michael S. Tsirkin <mst@xxxxxxxxxx>"
[am "t"]
signoff = "Tested-by: Michael S. Tsirkin <mst@xxxxxxxxxx>"
and now:
git am -s art
adds all 3 signatures when applying the patch.
Any help will be appreciated.
