Re: [certi-dev] Trying to use CERTI with regions

[Mattias Helsing]

Hi,
I whipped up an example to show my problem. I used an example from the test directory and modified it to fit how we use HLA. The tar contains 2 separate programs, where test_RoutingSpacesSimple.cc shows the initial problem we get. That is - calling notifyAboutRegionModified throws RegionNotKnown. The test_RoutingSpaces.cc file is basically identical to test_RoutingSpaces.cc but also creates an object and updates it. This shows some errors that I guess are the product of the previous error . I created a test_Space.fed which I used to reproduce the error here which is included in the tar. I also included the Makefile I used to create the examples for reference. I usually prefer cmake but for tiny programs like this make is easier. I am on Ubuntu linux and using CERT-3.4.1. Anyway it's a start. Tell me what to change and I will.

cheers
Mattias

hi again,
and thanks for the quick reply. I'll whip together a small test app as soon as possible.

I'm afraid that region has been unused for quite a time now.
Since we don't currently have a regression test for that as well it has been
untested as well.

I would suggest you write a possible standalone test which exhibits your issue
Then I'll help you to:

1) Add this test to our HLA_TestSuite
    http://cvs.savannah.gnu.org/viewvc/applications/HLA_TestsSuite/?root=certi

2) Investigate and solve the issue with you.

I'll check may be this is an error in the CERTI fed parser grammar.

Like I said smallest standalone C++ test case would be a very good start.
