Add a struct spa_log_topic that allows for logical grouping of messages. The new macros spa_log_logt() and spa_log_logtv() take a topic as argument, the topic's level acts as filter. A new macro spa_log_topic_init() initializes a topic. By default a topic inherits its logger's debug level but a logger implementation may set that topic to a specific fixed log level. The various spa_log_*() macros transparently wrap new and old implementations: - if the implementation is version 0, the new logt() calls drop the topic and get routed into the old log() calls - if the implementation is version 1, the old log() calls use a NULL topic and get routed into the new logt() calls All spa_log_* macros use the SPA_LOG_DEFAULT_TOPIC topic (NULL), it is up to the caller to redefine that. Alternatively, use spa_logt_* to pass an explicit topic. There is one crucial flaw in this implementation: log topics are initialized to their target level by the current logger. Where a topic is initialized but the logger is switched later, the topic is not automatically re-initialized. Ultimately this shouldn't matter for real-world use-cases. |
