[ace-users] ACE/TAO Logging

[Michael T. Carter]

"ACE is behaving as defined." is a valid statement to a certain extent,
in both 5.4 and new 5.5 versions.  The initial processing of the svc.conf
(logsvc.conf in my case) file is working as expected in both.  However,
I do not think the ACE_Service_Config::reconfigure() is working in the
5.5 versions.  Even just using the ACE code without the ORB_init, the
reconfigure complains with the following from the ACE::debug() output:

beginning reconfiguration at Wed Jul 18 08:24:09 2007
ACE (28484|182897092416) STDG::<ctor>, repo=0x5026c0 [1],
   name=logsvc.conf, type=0x5236f0, impl=(nil), object=(nil),
   active=0 - inserting dummy forward
ACE (28484|182897092416) SR::insert - repo=0x5026c0 [1] (1024),
   name=logsvc.conf, type=(nil), object=(nil), active=0
ACE (28484|182897092416) Service_Config_Guard:<ctor> -
   repo=0x5026c0 superceded by repo=0x5026c0
ACE (28484|182897092416) SG::process_directives_i, repo=0x5026c0 -
   <from file>
ACE (28484|182897092416) SG::initialize - repo=0x5026c0,
   looking up dynamic service 'Logger' to initialize
ACE (28484|182897092416) SG::initialize - repo=0x5026c0,
   Logger is already initialized. Remove before re-initializing.
ACE (28484|182897092416) Dynamic_Node::apply - Did dynamic on Logger 
(yyerrno=0)

So, since the initial ACE processing of the svc.conf file worked, then
it never did reconfigure the logger and it continued to work afterwards.

Just wanted to clear this up . . . I hope.
