Is it really deprecated? A quick search through the code shows it is
still there.
DoutStreamBuff shows:
// If conf->log_file was specified, that takes the highest priority
if (!conf->log_file.empty()) {
string log_file(normalize_relative(conf->log_file.c_str()));
if (conf->log_per_instance) {
But why is log_dir still there?
But you're right, for regular logging log file should be used. Still,
why is log dir still there?
