Introduced PCRE2_CFLAGS, PCRE2_LDADD, and PCRE2_LDFLAGS in all relevant Makefile.am files to align with the existing PCRE_* variable usage. This change addresses potential issues with linking and configuration for builds on macOS GitHub runners.
These modifications aim to resolve the build failure observed exclusively in the macOS environment while maintaining compatibility across other platforms. Testing will confirm if this adjustment corrects the issue.
- 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.
- Because the lifetime of the RuleMessage instances do not extend beyond
the lifetime of the enclosing RuleWithActions & Transaction,
RuleMessage can just reference it and simplify its definition.
- Additionally, make the references const to show that it doesn't modify it.
- Replace RuleMessage copy constructor with default implementations.
- Removed unused RuleMessage assignment operator (which cannot be implemented
now that it has reference members).
- Removed constructor from RuleMessage pointer.
- Addressed Sonarcloud suggestions: Do not use the constructor's
initializer list for data member "xxx". Use the in-class initializer
instead.
- 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.
- 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
