From 1d44f7584a713ab24e1ead541a8c85e176b99fd2 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sat, 4 Jul 2015 12:11:22 +0200 Subject: busctl: flush stdout after dumping data Running `busctl monitor` currently buffers data for several seconds / kilobytes before writing stdout. This is highly confusing if you dump in a file, ^C busctl and then end up with a file with data of the last few _seconds_ missing. Fix this by explicitly flushing after each signal. --- src/libsystemd/sd-bus/busctl.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/libsystemd/sd-bus/busctl.c b/src/libsystemd/sd-bus/busctl.c index 39caa4e7d6..5011c270a0 100644 --- a/src/libsystemd/sd-bus/busctl.c +++ b/src/libsystemd/sd-bus/busctl.c @@ -1137,6 +1137,7 @@ static int monitor(sd_bus *bus, char *argv[], int (*dump)(sd_bus_message *m, FIL if (m) { dump(m, stdout); + fflush(stdout); if (sd_bus_message_is_signal(m, "org.freedesktop.DBus.Local", "Disconnected") > 0) { log_info("Connection terminated, exiting."); -- cgit v1.2.3-54-g00ecf
