Dear Equalizer developers,
Recently I've started porting and MPK based application to Equalizer. In
order to initialize the configuration, the old application enabled the
user to provide a configuration at runtime. In Equalizer that's trickier
to do because I need to start the eqServer from my application.
So instead of doing that I'd like to use a local server inside the
application node process and use Server::useConfig to give the
configuration as a string. I know the function is undocumented and may
disappear but in my case, it's useful, unless there is an easier way of
starting the server with a user given configuration.
I've written a small test, which now is working. However it was crashing
in the beginning and after some debugging I've come across something
that, to me, seems to be a bug in Server::useConfig. Analyzing the code
I've found that there is a difference between chooseConfig and useConfig
in the sequence of operations performed in the server, while the first
one calls Server::addConfig for the default config at some moment, the
latter doesn't.
After the following change in Server::_cmdUseConfig:
EQINFO << "Using config: " << endl << Global::instance() << config
<< endl;
config->setApplicationNetNode( node );
+addConfig( config );
mapConfig( config );
the test application works.
Is that a bug or am I doing something wrong in my test program (find the
source attached)?
Thanks and best regards,
Juan Hernando
