v3.0.14
Removed usage of pthreads and replaced with std C++ features - Replaced pthread_mutex_t in modsecurity::operators::Pm with std::mutex - Replaced pthread's thread usage in reading_logs_via_rule_message example with std::thread. - Simplified and modernized C++ code. - Removed unnecessary includes of pthread.h
Added const reported by cppcheck 2.14
Avoid passing RuleMessage by std::shared_ptr and use a reference instead. - 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.
Adjusted pthread LDFLAG in examples required for multithreading. - Some versions of gcc/libc require setting the pthread flag when using std::thread, which to implement it. - This was found compiling the library in a Debian (bullseye) container.
Fix modsecurity-regression-test-secremoterules.txt URL in example
Adding multithreaded example from issue #3054 (by airween) - Rewritten to use C++ libModSecurity API and std::thread (instead of pthreads)
