| Did_not_reach_eof_for of Core.Time.Span.t | (** Did_not_reach_eof_for span occurs if it has been longer than
eof_latency_tolerance since stat detected that there is new data in the file
and the file tail processed all the new data. The span is how long it has been
since stat detected new data in the file. *) |
| Reached_eof | (** Reached_eof occurs whenever the file tail reaches the end of file, irrespective
of whether there has previously been a Did_not_reach_eof_for warning. *) |
| Delayed_due_to_null_reads_for of Core.Time.Span.t | (** Delayed_due_to_null_reads_for span occurs when the file tail is unable to get
data from the file, because the data being read has null ('\000') characters. The
span is how long it has been attempting to read and been getting nulls. This
warning will only occur if retry_null_reads = true. This warning will be
repeated until the null reads stop. *) |
| No_longer_delayed_due_to_null_reads | (** No_longer_delayed_due_to_null_reads occurs after a nonempty sequence of
Delayed_due_to_null_reads_for warnings, once the file tail gets a read that does
not contain null reads. *) |
