The direct execution of application-level code by a watch handler is troublesome because those handlers are executed at the I/O signal level. In the concrete case, the watch handler got recursively called because the handler called _handle_config (application-code), which called the VFS, which in turn performed a wait_and_dispatch_one_io_signal, which again invoked the watch handler. The patch works around the problem by letting the watch notification trigger the application-level signal for the _config_handler. Fixes #4091 |

This directory is a source-code repository containing Genode-specific services and applications. In contrast to the components that come with the 'os' repository, programs contained in 'gems' are able to leverage the functionalities provided by higher-level repositories such as 'libports'. To use the 'gems' repository, make sure to also add those repositories to your build configuraion.
