As per the `sd_notify` manual: > A field carrying the monotonic timestamp (as per CLOCK_MONOTONIC) formatted > in decimal in μs, when the notification message was generated by the client. > This is typically used in combination with "RELOADING=1", to allow the > service manager to properly synchronize reload cycles. See systemd.service(5) > for details, specifically "Type=notify-reload". Thus this change allows users with a recent systemd to switch to `Type=notify-reload`, should they desire to do so. Correct behavior was verified with a Fedora 39 VM. see systemd/systemd#25916 [wla: the service file should be updated this way:] diff --git a/admin/systemd/haproxy.service.in b/admin/systemd/haproxy.service.in index 22a53d8aab..8c6dadb5e5 100644 --- a/admin/systemd/haproxy.service.in +++ b/admin/systemd/haproxy.service.in @@ -8,12 +8,11 @@ EnvironmentFile=-/etc/default/haproxy EnvironmentFile=-/etc/sysconfig/haproxy Environment="CONFIG=/etc/haproxy/haproxy.cfg" "PIDFILE=/run/haproxy.pid" "EXTRAOPTS=-S /run/haproxy-master.sock" ExecStart=@SBINDIR@/haproxy -Ws -f $CONFIG -p $PIDFILE $EXTRAOPTS -ExecReload=@SBINDIR@/haproxy -Ws -f $CONFIG -c $EXTRAOPTS -ExecReload=/bin/kill -USR2 $MAINPID KillMode=mixed Restart=always SuccessExitStatus=143 -Type=notify +Type=notify-reload +ReloadSignal=SIGUSR2 # The following lines leverage SystemD's sandboxing options to provide # defense in depth protection at the expense of restricting some flexibility Signed-off-by: William Lallemand <wlallemand@haproxy.com>
