* jau::function: Use optimized Static Polymorphic `delegate_t<R(A...)>` ↵Sven Gothel2022-10-073-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (footprint + performance) Keep orig Runtime Polymorphic as `test/function2.hpp` for comparison and review. delegate_t<R(A...)> allows fast path target function invocation. This static polymorphous object, delegates invocation specific user template-type data and callbacks and allows to: - be maintained within function<R(A...)> instance as a member - avoiding need for dynamic polymorphism, i.e. heap allocated specialization referenced by base type - hence supporting good cache performance - avoid using virtual function table indirection - utilize constexpr inline for function invocation (callbacks) Impact: - Memory footprint reduced (64bit) - lambda, member: 64 -> 48 bytes, i.e. 25.00% less size - capval, capref: 56 -> 48 bytes, i.e. 14.29% less size - Performance (linux-arm64, raspi4, gcc, mean @ 600 samples): - member_jaufunc: 7.34998 -> 5.3406 ms, i.e. 27.34% perf. gain - becoming faster than member_stdbind_unspec - lambda_jaufunc: 6.89633 -> 5.52684 ms, i.e. 19.86% perf. gain - aligning most trivial-types to similar performance - Performance differences on linux-amd64 high-perf machine - Less significant than linux-arm64 - Probably due to better CPU caching, memory access, branch prediction, etc. - member_jaufunc: 1.880 -> 1.848 ms, i.e. ~2% perf. gain (too small) - lambda_jaufunc: 1.871 -> 1.851 ms, i.e. ~1% perf. gain (too small) - Lines of code incl. comments: - From 1287 -> 1674 lines, i.e. 30% added lines of code - Added code used for manual static polymorphism, see above. - Performance methodology - New code test - nice -20 ./test_functional2_perf --benchmark-samples 600 - Old code test - nice -20 ./test_functional1_perf --benchmark-samples 600 +++ Optimization of func::member_target_t<...> using `gcc` Utilizing GCC C++ Extension: Pointer to Member Function (PMF) Conversion to function pointer - Reduces function pointer size, i.e. PMF 16 (total 24) -> function 8 (total 16) - Removes vtable lookup at invocation (performance) - Pass object this pointer to function as 1st argument - See [GCC PMF Conversion](https://gcc.gnu.org/onlinedocs/gcc/Bound-member-functions.html#Bound-member-functions)
* functional: Add general lambda support, revise API doc, have native target ↵Sven Gothel2022-09-192-1/+2
| | | | | | | | | | function size accessible (and show in toString() Also, to avoid any template type deduction error, have the internally used `function(std::shared_ptr<target_type> _funcPtr) noexcept` made explicit as `explicit function(const void* dummy, std::shared_ptr<target_type> _funcPtr) noexcept` Adopted test_functional01.cpp and test_functional_perf.hpp

| | | | | | | | | | | | | | | template definition and default c++ naming scheme (function_def.hpp -> functional.hpp) Changes - Instead of FunctionDef<R, A1, A2> -> function<R(A1, A2)> - Added support for void return type - C++ naming scheme - Enhance unit tests a little. Examples: - jau::function<bool(int)> func = jau::bind_member(&i1, &MyClass::m_func1); - jau::function<void(int)> func = jau::bind_member(&il, &MyClass::m_func2); - ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | Build scripts - setup-machine-arch.sh - set os_name { 'linux' or 'freebsd' } - skip syslibdir for non linux - be quite if given arg "-quiet" - Set JAVA_HOME (if not done yet) - Set JUNIT_CP (if not done yet) - adopted all build/test scripts C++ compilation: - drop libatomic on all non Linux OS - Set SYS_INCLUDE_DIRS w/ FreeBSD += /usr/local/include, use it in compilation - FreeBSD: Set CMAKE_SYSTEM_PREFIX_PATH={/usr;/usr/local} - Use find_library() for LIBCURL_LIBNAME and LIBUNWIND_LIBNAME w/ REQUIRED if selected - Test: ownership_fix_tag: Use group 44(video) as defined in FreeBSD, Debian and Ubuntu - use 'chgrp -f' to not complain on errors, continue build OS/C++ file locations: - mini_httpd Java file locations: - openjdk - junit4 + hamcrest - IOUtil.getExeTestShellCode(): FreeBSD uses /bin/test as /bin/true is n/a (for executable temp jar dir, i.e. fat jars)
