Mark Salyzyn e9c9106fbb liblog: __android_log_is_loggable support global properties ... (cherry pick from commit c158456f50) - Add support for "log.tag" and "persist.log.tag" global logging properties, effectively a runtime default minimum logging level. - Add a thread-safe single level cache plus selective logic for the four properties being checked to help speed up logging decision on subsequent identical calls. - Using new __system_property_area_serial() to make for efficient (<100ns) handling of cache misses. Despite adding two new properties, we are 8 times faster on subsequent calls even if the properties do not exist. - A NULL or blank tag is no longer directed to return default, it will check the pair of global logging properties first. - Add liblog.is_loggable gTest - Fixup liblog.android_logger_get_, allow no content in crash buffer - Fixup liblog.max_payload, lowered logd priority increases latency Bug: 19544788 Bug: 21696721 Change-Id: Ideb887755aa3f1fd14a2603bda1fe23cba49642c		2015-06-15 07:34:07 -07:00
