Subject: [PATCH] ppswatch: Fix quitting after signal
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
The ppswatch quitting mechanism relies on time_pps_fetch() being
|
|
interrupted by a signal. Therefore when ppswatch receives a signal while
|
|
it's not within time_pps_fetch() it would print the stastics but not
|
|
quit the application.
|
|
|
|
I can reliably reproduce the issue on my embedded machine (using the
|
|
pps-gpio driver) by running the following snippet:
|
|
./ppswatch -a /dev/pps3 &
|
|
pid=$!
|
|
sleep 3
|
|
kill $pid
|
|
|
|
This patch fixes the issue.
