[omniORB] does persistent example work?

[Jonathan Clark]

First off, I'm using ORB 3.0 pre-release under Win2k.

When I run the persistent_objref sample program I get different IOR's each
time I run it for example:

run 1
-----
IOR:010000000d00000049444c3a4563686f3a312e3000000000010000000000000032000000
010100000c0000003139322e3136382e322e3200390b000016000000ff6d7920706f61006d79
206563686f206f626a656374

   >>>catior
   Type ID: "IDL:Echo:1.0"
   Profiles:
   1. IIOP 1.0 192.168.2.2 2873 ".my poa.my echo object"

run 2
-----
IOR:010000000d00000049444c3a4563686f3a312e3000000000010000000000000032000000
010100000c0000003139322e3136382e322e32003a0b000016000000ff6d7920706f61006d79
206563686f206f626a656374

  >>>catior
  Type ID: "IDL:Echo:1.0"
  Profiles:
  1. IIOP 1.0 192.168.2.2 2874 ".my poa.my echo object"

this occurs regardless of if I use no
arguments, -ORBInitialPort, -ORBInitialHost, or any combination.

Stepping through the source code, it appears that the initial port that is
bound to is always chosen by the OS:

  objectAdapter.cc:

  // here 0 is always used to bind to a port (???)
  _tcpEndpoint e((const CORBA::Char*) hostname, 0);
  factory->instantiateIncoming(&e, 1);


I noticed there is some code in corbaOrb.cc that looks like this:

    if( bootstrapAgentHostname ) {
      // The command-line option -ORBInitialHost has been specified.
      // Override any previous NamesService object reference
      // that may have been read from the configuration file.
      omniInitialReferences::remFromFile("NameService");
      omniInitialReferences::remFromFile("InterfaceRepository");

omniInitialReferences::initialise_bootstrap_agent(bootstrapAgentHostname,
							bootstrapAgentPort);
    }

Here initialize_bootstrap_agent appears to be important - though it is only
called
if -ORBInitialHost is set... shouldn't that *also* be if
only -ORBInitialPort is set?...
i.e. currently if only -ORBInitialPort is set then
initialise_bootstrap_agent is not called.

When initialize_bootstrap_agent *is* called, the proper command-line port is
encoded
into a partial IOR somewhere in initRefs.cc, but this is never used on the
later bind!  I
have the feeling I'm missing something obvious, or is this a bug?

If I change objectAdapter.cc to use a fixed port like this
_tcpEndpoint e((const CORBA::Char*) hostname, MY_FIXED_PORT);  I get a
persistant IOR.
