- Avoids copying std::shared_ptr when lifetime of the RuleMessage
is controlled by the caller.
- The RuleMessage instance is created in RuleWithActions::evaluate and
then used to call the overloaded version of this method that is
specialized by subclasses.
- Once the call to the overloaded method returns, the std::shared_ptr
is destroyed as it's not stored by any of the callers, so it can
be replaced with a stack variable and avoid paying the cost of
copying the std::shared_ptr (and its control block that is
guaranteed to be thread-safe and thus is not a straightforward
pointer copy)
- Introduced RuleMessage::reset because this is required by
RuleWithActions::performLogging when it's not the 'last log', the rule
has multimatch and it's to be logged.
- The current version is creating allocating another instance of
RuleMessage on the heap to copy the Rule & Transaction related state
while all the other members in the RuleMessage are set to their
default values.
- The new version leverages the existent, unused and incomplete
function 'clean' (renamed as 'reset') to do this on the current
instance.
- Notice that the current code preserves the value of m_saveMessage,
so 'reset' provides an argument for the caller to control whether
this member should be reinitialized.
