----------------------------------------
Summary: Verify regex properties in processors in case it is set
to empty
Key: MINIFICPP-1830
URL: https://issues.apache.org/jira/browse/MINIFICPP-1830
Project: Apache NiFi MiNiFi C++
Issue Type: Bug
Reporter: Gábor Gyimesi
When we moved from RegexUtils to std::regex our RegexUtilsTests were removed,
but there were some changes between the functionalities. In case an empty regex
is set std::regex matches on an empty pattern but our old RegexUtils did not.
When reverting to RegexUtils from std::regex due to an std::regex bug, we
stayed with the std::regex behaviour.
There are some processors where a property sets a regex pattern. If that
property is left empty then the processor's behavior may have changed. We
should check all processors where these a regex property is present and change
the member regex to std::optional and check if the member is set before trying
to match that regex.
