Which is a terrible for Squid helpers. The PP interpreters are optimized for short single runs, Squid helpers a long-term daemons. #2 - outputting empty line on startup. Will result in (best case) helpers dying constantly with "unexpected response" errors by Squid, or (worst case) incorrect alignment between Squid queries and the helper responses. Resulting in incorrect HTTP behaviour. #3 - infinite loop. while(1) without any termination/exit/break condition will result in Squid not being able to shutdown the helper for reconfigure and log rotation. Eventually blocking any further traffic through the proxy. #4 - opening a new stdin FD on each infinite loop cycle. Resulting in a vast number of FD churning over. see #3 #4b - resource leaks. Not closing stdin pointers allocated in #4. see #3 #5 - using the results of fgets() without checking for existence first. Passing EOF/false/null to rtrim() will produce an object. see #3 #6 - using integer-converter comparison to compare strings. ($gg == ""). Meet the '===' family of operators in PHP they are your friends. #7 - using stored-value test on a nil object. Meet isempty(), isset(), is_null() in PHP they are your friends. ... probably more, but less obvious.
