WP_DEFINE_LOCAL_LOG_TOPIC ("tests")
log: implement a log topics system, like pipewire The intention is to make checks for enabled log topics faster. Every topic has its own structure that is statically defined in the file where the logs are printed from. The structure is initialized transparently when it is first used and it contains all the log level flags for the levels that this topic should print messages. It is then checked on the wp_log() macro before printing the message. Topics from SPA/PipeWire are also handled natively, so messages are printed directly without checking if the topic is enabled, since the PipeWire and SPA macros do the checking themselves. Messages coming from GLib are checked inside the handler. An internal WpLogFields object is used to manage the state of each log message, populating all the fields appropriately from the place they are coming from (wp_log, spa_log, glib log), formatting the message and then printing it. For printing to the journald, we still use the glib message handler, converting all the needed fields to GLogField on demand. That message handler does not do any checks for the topic or the level, so we can just call it to send the message. 2023-05-16 11:51:29 +03:00			`/* WirePlumber`
