* log: lower IPC connection issues to info level ... in handle_new_connection(). The caller has better context for whether a problem merits a warning or error, and the function's return code is sufficiently descriptive to do so. Some problems may be expected or able to be worked around. For example, Pacemaker's crm_mon attempts to contact pacemakerd IPC. On a Pacemaker Remote node, that IPC will be unavailable, and crm_mon can check the libqb return code to detect and handle that situation gracefully. * log: lower some ringbuffer debug messages to trace level They're rather noisy, with every shm-based IPC connection generating multiple obscure messages like: debug: shm size:1048589; real_size:1052672; rb->word_size:263168 and every disconnect generating the rather unhelpful: debug: qb_ipcc_disconnect() along with multiple messages like: debug: Closing ringbuffer: /dev/shm/qb-10986-11014-34-26VRvs/qb-request-cmap-header All of these seem appropriate to trace level. |

libqb
What is libqb?
libqb is a library with the primary purpose of providing high-performance, reusable features for client-server architecture, such as logging, tracing, inter-process communication (IPC), and polling.
libqb is not intended to be an all-encompassing library, but instead provide focused APIs that are highly tuned for maximum performance for client-server applications.
