From c52afaf8b5c96136fe20e5d5a1332121d3b09ee9 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Sat, 10 Sep 2022 12:15:20 -0400 Subject: Add gRPC API implementation Changes: - Rename the existing daemon to applaunchd-dbus, and add a new version that exposes a gRPC based implementation of the API based on the protobuf definition added in a top-level protos directory. Having both the D-Bus and gRPC APIs exposed by a single daemon was posing difficulties around startup dependencies stemming from D-Bus activation of the daemon. Since the end goal is dropping the D-Bus API entirely, it is easier to just add a second daemon for gRPC that will eventually be the only one present. - To facilitate building the two implementations, a significant amount of code refactoring has been done to move things from the D-Bus API implementing app_launcher.[ch] to systemd_manager.[ch] so the code can be reused. - All use of the systemd D-Bus library except for the path encoding helper function has been replaced with GDBus. The systemd interface wrapper code was generated with gdbus-codegen from XML files captured via introspection on a running system. The motivation for this change was to avoid multithreading issues with sd_bus exposed when calling into it from the gRPC threads. - The copyright headers in the source files have been tweaked to remove the Apache license boilerplate in favour of a SPDX license tag. Notes: - The gRPC API differs slightly from the D-Bus one in that it has a single status streaming RPC method as opposed to the separate signals for application started or terminated that the D-Bus API has. - The gRPC API is currently unauthenticated, the aim is to circle back and implement authentication once a consensus can be reached on what mechanism should be used (fixed JWT configuration, OAuth, etc.).
