capture_reset()

Here is the caller graph for this function:

test_first_message_logged()

static void test_first_message_logged ( void  )

static

The first message from a fresh entry is logged, even in the first second of the process.

fr_time() counts from fr_time_start(). A fresh entry has last_complained of zero, which is second 0, and a message in second 0 of the process compared equal to it and was counted as a repeat instead of being logged.

Here is the call graph for this function:

test_repeat_count_reported()

static void test_repeat_count_reported ( void  )

static

A message one second after the last one reports the repeats suppressed in between.

The macro set last_complained to now before computing the time since the last complaint, which was then always zero, and the suffix never appeared.

Here is the call graph for this function:

test_repeat_suppressed()

static void test_repeat_suppressed ( void  )

static

A second message in the same second is counted, not logged.
