[SMS D-Bus 11/19] sms: send PropertyChanged signals on state change

From: Inaky Perez-Gonzalez <inaky.perez-gonzalez(a)intel.com&gt; This hooks sms_msg_stch_dbus_cb() into the SMS state change callback so that a D-Bus signal will be emitted whenever an SMS Message transitions state. This allows a client to track, if desired, what is going on with the SMS Message it cares about. --- src/sms.c | 36 +++++++++++++++++++++++++++++++++++- 1 files changed, 35 insertions(+), 1 deletions(-) diff --git a/src/sms.c b/src/sms.c index 06dfd08..fbaa271 100644 --- a/src/sms.c +++ b/src/sms.c @@ -790,6 +790,40 @@ struct tx_queue_entry *sms_msg_send( } /* + * Send a PropertyChange signal when the state changes + * + * In D-Bus we don't care about the initial state transition to + * _QUEUED, as the object path hasn't even been published yet in the + * bus. + */ +static +void sms_msg_stch_dbus_cb(void *_dbus_path, + enum ofono_sms_tx_state new_state) +{ + char *dbus_path = _dbus_path; + DBusConnection *dbus_conn = ofono_dbus_get_connection(); + DBusMessage *dbus_signal; + DBusMessageIter iter; + const char *property = "State"; + const char *new_state_str; + + if (new_state == OFONO_SMS_TX_ST_QUEUED) + return; + + dbus_signal = dbus_message_new_signal( + dbus_path, SMS_MSG_INTERFACE, "PropertyChanged"); + + if (!dbus_signal) + return; + + dbus_message_iter_init_append(dbus_signal, &iter); + dbus_message_iter_append_basic(&iter, DBUS_TYPE_STRING, &property); + new_state_str = ofono_sms_tx_state_to_string(new_state); + dbus_message_iter_append_basic(&iter, DBUS_TYPE_STRING, &new_state_str); + g_dbus_send_message(dbus_conn, dbus_signal); +} + +/* * D-Bus: Send a SMS text message * * @conn: D-Bus connection @@ -820,7 +854,7 @@ static DBusMessage *dbus_sms_msg_send(DBusConnection *conn, DBusMessage *msg, */ dbus_path = g_strdup_printf("%s/%04x", sms_path, 0); sms_msg = sms_msg_send(sms, to, text, SMS_MSG_SEND_HISTORY, - NULL, + sms_msg_stch_dbus_cb, sms_msg_dbus_destroy, dbus_path); -- 1.6.6.1
