2022-06-10services: jami: Modernize to adjust to Shepherd 0.9+ changes....This partially fixes <https://issues.guix.gnu.org/54786>, allowing the 'jami' and 'jami-provisioning' system tests to pass again. In version 0.9.0, Shepherd constructors are now run concurrently, via cooperative scheduling (Guile Fibers). The Jami service previously relied on blocking sleeps while polling for D-Bus services to become ready after forking a process; this wouldn't work anymore since while blocking the service process wouldn't be given the chance to finish starting. The new reliance on Fibers in Shepherd's fork+exec-command in the helper 'send-dbus' procedure also meant that it wouldn't work outside of Shepherd anymore. Finally, the 'start-service' Shepherd procedure used in the test suite would cause the Jami daemon to be spawned multiple times (a bug introduced in Shepherd 0.9.0). To fix/simplify these problems, this change does the following: 1. Use the Guile AC/D-Bus library for D-Bus communication, which simplify things, such as avoiding the need to fork 'dbus-send' processes. 2. The non-blocking 'sleep' version of Fiber is used for the 'with-retries' waiting syntax. 3. A 'dbus' package variant is used to adjust the session bus configuration, tailoring it for the use case at hand. 4. Avoid start-service in the tests, preferring 'jami-service-available?' for now. * gnu/build/jami-service.scm (parse-dbus-reply, strip-quotes) (deserialize-item, serialize-boolean, dbus-dict->alist) (dbus-array->list, parse-account-ids, parse-account-details) (parse-contacts): Delete procedures.

(jami-dbus-session-activation): Write a D-Bus daemon configuration file at '/var/run/jami/session-local.conf'. (jami-shepherd-services): Add the closure of guile-ac-d-bus and guile-fibers as extensions. Adjust imported modules. Remove no longer used parameters. <jami-dbus-session>: Use a PID file, avoiding the need for the manual synchronization. <jami>: Set DBUS_SESSION_BUS_ADDRESS environment variable. Poll using 'jami-service-available?' instead of 'dbus-service-available?'. * gnu/tests/telephony.scm (run-jami-test): Add needed Guile extensions. Set DBUS_SESSION_BUS_ADDRESS environment variable. Adjust all tests to use 'jami-service-available?' to determine if the service is started rather than the now problematic Shepherd's 'start-service'. Maxim Cournoyer
