13431 FIX Fix async checks blocked by realtime checks
When realtime checks were configured, async checks were not executed.
The problem (and the fix) can be reproduced by the following test script:
fork_away() {
echo "start" >> /tmp/testing
date >> /tmp/testing
sleep 2
date >> /tmp/testing
echo "end" >> /tmp/testing
}
main_1_fine() {
fork_away &
}
main_2_broken() {
(
fork_away &
) | cat
}
main_3_fine() {
(
fork_away > /dev/null &
) | cat
}
main_4_broken() {
(
true && fork_away > /dev/null &
) | cat
}
main_5_fine() {
(
{ true && fork_away; } > /dev/null &
) | cat
}
main_6_fine() {
(
true && { fork_away > /dev/null & }
) | cat
}
main() {
# uncomment the one you want to test
# the bash script is expected to exit immediately
# a log line should be printed in /tmp/log after the script finished.
# main_1_fine
# main_2_broken
# main_3_fine
# main_4_broken
# main_5_fine
# main_6_fine
echo "done!"
}
main
