[PATCH libvirt v2 6/9] remote/rpc: Use virNetServerGetProgram() to determine the program

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use virNetServerGetProgram() to determine the virNetServerProgram
instead of using hard coded global variables. This allows us to remove
the global variables @remoteProgram and @qemuProgram as they're now no
longer necessary.

Note: I'm not 100% sure that there is no case where the lock for
@client is already held by the thread which is calling
virNetServerGetProgram and thus the lock order would be violated (the
lock order has to be @server -> @client in the violating case it would
be @client -> @server and therefore a deadlock might occur).
