--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This shows the bug on trunk, which only affects the quality of error reporting
when an error occurs:
#include <fstream>
#include <filesystem>
using std::filesystem::path;
using std::filesystem::perms;
int main(int argc, char** argv)
{
if (argc < 2)
return 1;
path dir(argv[1]);
std::error_code ec;
create_directory(dir, ec); // ignore errors
std::ofstream file{dir/"file"};
permissions(dir, perms::owner_read|perms::owner_exec);
remove_all(dir);
}
$ ./a.out nonwritable
terminate called after throwing an instance of
'std::filesystem::__cxx11::filesystem_error'
what(): filesystem error: cannot remove all: Directory not empty
[nonwritable]
Aborted (core dumped)
Instead of reporting a permission denied error it says the directory is not
empty.
