This patch reduces the number of exception types by facilitating globally defined exceptions for common usage patterns shared by most services. In particular, RPC functions that demand a session-resource upgrade not longer reflect this condition via a session-specific exception but via the 'Out_of_ram' or 'Out_of_caps' types. Furthermore, the 'Parent::Service_denied', 'Parent::Unavailable', 'Root::Invalid_args', 'Root::Unavailable', 'Service::Invalid_args', 'Service::Unavailable', and 'Local_service::Factory::Denied' types have been replaced by the single 'Service_denied' exception type defined in 'session/session.h'. This consolidation eases the error handling (there are fewer exceptions to handle), alleviates the need to convert exceptions along the session-creation call chain, and avoids possible aliasing problems (catching the wrong type with the same name but living in a different scope). |

This directory contains ports of popular 3rd-party applications to Genode. The 'ports' repository follows the line of the 'libports' repository. For instructions about downloading and building 3rd-party applications, please refer to 'libports/README'. Dependencies from other repositories ------------------------------------ Application provided by the 'ports' repository typically expect a rich runtime environment, including shared libraries provided by the 'libports' repository. Hence, 'ports' depends on 'libports'.
