[amitanandaiyer]

To look for the first few lines of stack trace where the lock was requested:

Useful for making sense of the stack traces cat ~/bin/process_tsan_failures.sh

if [[ $# -ne 1 ]]; then
    echo "Usage: $0 <log_file>"
    exit -1
fi
LOG_FILE=$1


grep -B 5 -A 25 -E "acquired here|acquired by" $LOG_FILE | awk  '
    BEGIN { max_looking = 5; looking = 0; }
    /=========/
    /thread/ {print ""}
    /acquired/ { looking = max_looking; }
    /lock/ { looking = looking + 1 }
    // { if (looking > 0) { looking = looking - 1; print $0 } } ' | grep -v -E -i "[^ ]lock[^ -]" | grep -v mutex_lock
