Any state may transition to the `Error` state at any time, + * and the daemon may disappear at any time. + * + * This plugin follows the state transitions signalled by the daemon, and + * updates the state of a single #GsApp instance (`os_upgrade`) to reflect the + * OS upgrade in the UI. + * + * Calling gs_plugin_eos_updater_refresh_metadata_async() will result in this + * plugin calling the `Poll()` method on the `eos-updater` daemon to check for a + * new update. + * + * Calling gs_plugin_app_upgrade_download() will result in this plugin calling + * a sequence of methods on the `eos-updater` daemon to check for, download and + * apply an update. Typically, gs_plugin_app_upgrade_download() should be called + * once `eos-updater` is already in the `UpdateAvailable` state. It will report + * progress information, with the first 75 percentage points of the progress + * reporting the download progress, and the final 25 percentage points reporting + * the OSTree deployment progress. The final 25 percentage points are currently + * faked because we can’t get reasonable progress data out of OSTree. + * + * The proxy object (`updater_proxy`) uses the thread-default main context from + * the gs_plugin_eos_updater_setup() function, which is currently the global default main + * context from gnome-software’s main thread. This means all the signal + * callbacks from the proxy will be executed in the main thread, and *must not + * block*. + * + * Asynchronous plugin vfuncs (such as + * gs_plugin_eos_updater_refresh_metadata_async()) are run in gnome-software’s + * main thread and *must not block*. As they all call D-Bus methods, the work + * they do is minimal and hence is OK to happen in the main thread. + * + * The other functions (gs_plugin_app_upgrade_download(), + * etc.) are called in #GTask worker threads. They are allowed to call methods + * on the proxy; the main thread is only allowed to receive signals and check + * properties on the proxy, to avoid blocking. Consequently, worker threads need + * to block on the main thread receiving state change signals from + * `eos-updater`. Receipt of these signals is notified through + * `state_change_cond`. This means that all functions which access + * `GsPluginEosUpdater` must lock it using the `mutex`. + * + * `updater_proxy`, `os_upgrade` and `cancellable` are only set in + * gs_plugin_eos_updater_setup(), and are both internally thread-safe — so they can both be + * dereferenced and have their methods called from any thread without + * necessarily holding `mutex`. + * + * Cancellation of any operations on the `eos-updater` daemon (polling, fetching + * or applying) is implemented by calling the `Cancel()` method on it. This is + * permanently connected to the private `cancellable` #GCancellable instance, + * which persists for the lifetime of the plugin. The #GCancellable instances + * for various operations can be temporarily chained to it for the duration of + * each operation. + * + * FIXME: Once all methods are made asynchronous, the locking can be dropped + * from this plugin. + */ + +static const guint max_progress_for_update = 75;
