Extended AMI4CCM prototype . Update all examples and tests for the changes in the -Glem - TAO_IDL option + TAO_IDL option. The behavior of this option has changed + dramatically, and will require that most user applications be + ported. Previously, -Glem would cause the IDL compiler to generate + a E.idl file containing local executor mapping for all interfaces + provided as ports by any components in the main translation unit. + Therefore, files with interfaces, but no components defined will + have empty E.idl files generated. Similarly, a file with no + interfaces defined, but with components defined would generate LEM + interfaces for interfaces provided by that component but not local + to the file in question. While this behavior simplified a + rudimentary use case where interfaces would be provided by only one + component, more complicated use cases were much more difficult to + achieve. + + The new behvior causes the IDL compiler to generate LEM IDL for all + interfaces within a given translation unit, regardless of whether or + not they are provided as ports by a component in the same + translation unit. Futhermore, if a component provides an interface + that is not defined with the translation unit of that compoment, it + is required that the user provide a #include directive to the + appropriate E.idl file which contains the required LEM interface for + the interfaces provided as facets. + + This new behavior is similar to the former behavior of -Glfa, and as + such the behavior of -Glfa has been changed to attempt to be + reflective of the old behavior of -Glem, and may be used as a + stopgap backwards compatibility measure. . In idl3_to_idl2 tool, replaced manual designation of IDL2-only files and resulting generated include of undecorated filename |
