With this change in place, the grafana service will signal
readiness to serve by writing "READY=1" to the path specified
through the NOTIFY_SOCKET environment variable. If this
environment variable is not present or empty, no notification
will happen. This notification is the standard systemd
mechanism for indicating a service is ready to serve. For
Grafana this may be a couple of seconds from startup due to
database migrations. This change also adjusts the Grafana
systemd service definition to make use of this feature.
Using the EncodeToString function from the encoding/hex package
is much faster than calling the fmt.Sprintf with %x
Benchmark results below with the following code
func BenchmarkHexPrint(b *testing.B) {
data := []byte("hellothere")
for n := 0; n < b.N; n++ {
// _ = fmt.Sprintf("%x", data)
_ = hex.EncodeToString(data)
}
}

The JoinUrlFragments function adds a trailing slash if to the proxy url
if the proxy path is an empty string. This fix removes that trailing
slash. Fixes#3847
