qdiriterator benchmark: test against std::filesystem
If c++17 is available and the header is available (not
experimental/filesystem) then we'll try
std::filesystem::recursive_directory_iterator as well.
Results on my PC (Windows, VS 2019):
PASS : tst_qdiriterator::posix(C:\depot\qt\main/src/corelib)
RESULT : tst_qdiriterator::posix():"C:\depot\qt\main/src/corelib":
23 msecs per iteration (total: 94, iterations: 4)
PASS : tst_qdiriterator::diriterator(C:\depot\qt\main/src/corelib)
RESULT : tst_qdiriterator::diriterator():"C:\depot\qt\main/src/corelib":
17 msecs per iteration (total: 71, iterations: 4)
PASS : tst_qdiriterator::stdRecursiveDirectoryIterator(C:\depot\qt\main/src/corelib)
RESULT : tst_qdiriterator::stdRecursiveDirectoryIterator():"C:\depot\qt\main/src/corelib":
6.7 msecs per iteration (total: 54, iterations: 8)
PASS : tst_qdiriterator::fsiterator(C:\depot\qt\main/src/corelib)
RESULT : tst_qdiriterator::fsiterator():"C:\depot\qt\main/src/corelib":
23 msecs per iteration (total: 92, iterations: 4)
And as a drive-by fix: move the 'data' function out of the private slots
so it is not invoked as a test function (it doesn't cause any problems
but is ultimately pointless).
