- Patch provided by bug reporter. Here is the description of the problem from the bug. First I discovered that the helper only sometimes throwing the error and quits even for the same values and queries. Also the timespan until the error happens was quite different for every restart of squid (minutes to hours). And it does not depend on the traffic on the proxy, even one connection could cause a crash while ten or hundrets won't. After a few days of testing different solutions and done a lot of debugging, redesigning the function did not fully solve the problem. Such standard things like checking the result variable for NULL (or it's equivalent "is None" in python) before evaluating it's subfunction produces the exact same error message. But with that knowledge it more and more turns out that python3 sometimes 'detects' the local return variable if it was a misused global. So for a full fix, the return variable also has to be initialized that python3 won't detect it's usage as an 'UnboundLocalError' to succesfully fix this bug. - LFS file updated to run patch before copying helper into place. - Update of rootfile not needed. - Bug reporter has been requested to raise this issue at the git repo for squid-asnbl.
