arpadboda commented on issue #612: MINIFICPP-854: Capture RTSP Frame URL: https://github.com/apache/nifi-minifi-cpp/pull/612#issuecomment-515504140 @phrocker : 1) env vars are inherited from the parent process, but can be overwritten. The overwrite we do doesn't effect the parent process (which is most probably a shell). How could the parent process (command line) overwrite the env var while MiNiFi is running? To be able to edit env vars while MiNiFi is running, the latter needs to be forked, which means copying env vars. 2) this concern I find valid, too, and in my opinion neither of the solutions we talked about (script, setting in code) protects against this. Moreover, I'm afraid we can't. What we can do is to check the env var in ontrigger logic to ensure it's still the same. In case it has been set to something else, we can log error and yield. Which might be better than doing something stupid, but still far from nice.
