/**
* @file qblog.h
* The logging API provides four main parts (basics, filtering, threading & blackbox).
*
* The idea behind this logging system is not to be prescriptive but to provide a
* set of tools to help the developer achieve what they want quickly and easily.
*
* @par Basic logging API.
* Call qb_log() to generate a log message. Then to write the message
* somewhere meaningful call qb_log_ctl() to configure the targets.
*
* Simplist possible use:
* @code
* main() {
* qb_log_init("simple-log", LOG_DAEMON, LOG_INFO);
* // ...
* qb_log(LOG_WARNING, "watch out");
* // ...
* qb_log_fini();
* }
* @endcode
*
* @par Configuring log targets.
* A log target can by syslog, stderr, the blackbox or a text file.
* By default only syslog is enabled.
*
* To enable a target do the following
* @code
* qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE);
* @endcode
*
* syslog, stderr and the blackbox are static (they don't need
* to be created, just enabled or disabled. However you can open multiple
* logfiles (32 - QB_LOG_BLACKBOX). To do this use the following code.
* @code
* mytarget = qb_log_file_open("/var/log/mylogfile");
* qb_log_ctl(mytarget, QB_LOG_CONF_ENABLED, QB_TRUE);
* @endcode
*
* Once your targets are enabled/opened you can configure them as follows:
* Configure the size of blackbox
* @code
* qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10);
* @endcode
*
* Make logging to file threaded:
* @code
* qb_log_ctl(mytarget, QB_LOG_CONF_THREADED, QB_TRUE);
* @endcode
*
* To workaround your syslog daemon filtering all messages > LOG_INFO
* @code
* qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_PRIORITY_BUMP,
* LOG_INFO - LOG_DEBUG);
* @endcode
*
* @par Filtering messages.
* To have more power over what log messages go to which target you can apply
* filters to the targets. What happens is the desired callsites have the
* correct bit set. Then when the log message is generated it gets sent to the
* targets based on which bit is set in the callsite's "target" bitmap.
* Messages can be filtered based on the:
* -# filename + priority
* -# function name + priority
* -# format string + priority
*
* So to make all logs from evil_fnunction() go to stderr do the following:
* @code
* qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD,
* QB_LOG_FILTER_FUNCTION, "evil_fnunction", LOG_TRACE);
* @endcode
*
* So to make all logs from totem* (with a priority <= LOG_INFO) go to stderr do the following:
* @code
* qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD,
* QB_LOG_FILTER_FILE, "totem", LOG_INFO);
* @endcode
*
* So to make all logs with the substring "ringbuffer" go to stderr do the following:
* @code
* qb_log_filter_ctl(QB_LOG_STDERR, QB_LOG_FILTER_ADD,
* QB_LOG_FILTER_FORMAT, "ringbuffer", LOG_TRACE);
* @endcode
*
* @par Threaded logging.
* To achieve non-blocking logging you can use threaded logging. So any
* calls to write() or syslog() will not hold up your program.
*
* Threaded logging use:
* @code
* main() {
* qb_log_init("simple-log", LOG_DAEMON, LOG_INFO);
* qb_log_ctl(QB_LOG_SYSLOG, QB_LOG_CONF_THREADED, QB_TRUE);
* // ...
* daemonize();
* // call this after you fork()
* qb_log_thread_start();
* // ...
* qb_log(LOG_WARNING, "watch out");
* // ...
* qb_log_fini();
* }
* @endcode
*
* @par A blackbox for in-field diagnosis.
* This stores log messages in a ringbuffer so they can be written to
* file if the program crashes (you will need to catch SIGSEGV). These
* can then be easily printed out later.
*
* @note the blackbox is not enabled by default.
*
* Blackbox usage:
* @code
*
* static void sigsegv_handler(int sig)
* {
* (void)signal (SIGSEGV, SIG_DFL);
* qb_log_blackbox_write_to_file("simple-log.fdata");
* qb_log_fini();
* raise(SIGSEGV);
* }
*
* main() {
*
* signal(SIGSEGV, sigsegv_handler);
*
* qb_log_init("simple-log", LOG_DAEMON, LOG_INFO);
* qb_log_filter_ctl(QB_LOG_BLACKBOX, QB_LOG_FILTER_ADD,
* QB_LOG_FILTER_FILE, "*", LOG_DEBUG);
* qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_SIZE, 1024*10);
* qb_log_ctl(QB_LOG_BLACKBOX, QB_LOG_CONF_ENABLED, QB_TRUE);
* // ...
* qb_log(LOG_WARNING, "watch out");
* // ...
* qb_log_fini();
* }
* @endcode
*
* @par Tagging messages.
* You can tag messages using the second argument to qb_logt() or
* by using qb_log_filter_ctl().
* This can be used to add feature or sub-system information to the logs.
*
* @code
* const char* my_tags_stringify(uint32_t tags) {
* if (qb_bit_is_set(tags, QB_LOG_TAG_LIBQB_MSG_BIT) {
* return "libqb";
* } else if (tags == 3) {
* return "three";
* } else {
* return "MAIN";
* }
* }
* main() {
* // ...
* qb_log_tags_stringify_fn_set(my_tags_stringify);
* qb_log_format_set(QB_LOG_STDERR, "[%5g] %p %b");
* // ...
* qb_logt(LOG_INFO, 3, "hello");
* qb_logt(LOG_INFO, 0, "hello");
* }
* @endcode
* The code above will produce:
* @code
* [libqb] some message
* [three] info hello
* [MAIN ] info hello
* @endcode
