This is expected; the goal is to finish reading partial lines
before existing. This is useful with services that are writing a
large amount of logs, where the buffer length does not necessarily
align with a newline: after receiving the signal, the logger reads
until the next newline, processes the line, then exits.
No service should ever write a partial line at the end of their
lifetime.
However, I agree that the situation you're describing is not ideal
and s6-log should be more robust. I'm thinking of adding a timeout:
if s6-log hasn't received the end of a partial line n milliseconds
after receiving a terminating signal, then it should process the
partial line anyway and exit. What do you think?
