Sorry but unfortunately we are not backporting features in stable branches,
those are only meant for maintenance.
People who want to use the seamless reload should migrate to HAProxy 1.8, the
stable team won't support this feature in previous branches.
I've been keeping eye on this list about 1.8 related bugs and it does
not seem to me that 1.8 stable enough yet for production use. Too many
reports about high CPU usage and/or crashes.
We are still using 1.6 which finally seems to have stabilized enough for
production. When we started using 1.6 some years ago, we had many issues
with it which caused service interruptions. Would not want to repeat
that again.
Even with 1.7, processes would hang forever after reload (days,
sometimes weeks or until reboot). Really hard to debug, happens only
under production load.
I will look at patches provided by Dave. We are building HAproxy rpm-s
for ourselves anyway, applying some patches in spec file does not seem
to be that much additional work if indeed those would provide truly
seamless reloads.
