--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Thu Jan 17 15:31:59 2019 New Revision: 268034 URL: https://gcc.gnu.org/viewcvs?rev=268034&root=gcc&view=rev Log: PR libstdc++/88881 adjust filesystem::status and tests for mingw semantics On Windows stat("foo/bar/../.") will resolve to "foo" even if that is a non-directory and "foo/bar" does not exist. This is the expected behaviour and consistent with boost::filesystem, so don't try to correct it. The only unwanted behaviour is that stat("baz/") fails due to a mingw bug (fixed in mingw-w64 v6.0.0) so add a workaround. PR libstdc++/88881 * src/c++17/fs_ops.cc (canonical(const path&, error_code&)) [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Normalize path, to match behaviour of filesystem::exists. (create_directories(const path&, error_code&)): Add assertions. (status(const path&, error_code&)) [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Add workaround for bug in _wstat for paths with trailing slash. * testsuite/27_io/filesystem/operations/create_directories.cc: Adjust for expected behaviour on mingw. * testsuite/experimental/filesystem/operations/create_directories.cc: Likewise. * testsuite/27_io/filesystem/operations/temp_directory_path.cc: Use "TMP" instead of "TMPDIR" and clean environment before each test. Do not test permissions on mingw targets.
