Jonathan Wakely c7dde4a90a Share all recursive_directory_iterator state [LWG 2708] ... Implement the proposed resolution of LWG 2708 by moving the _M_options and _M_pending members out of the recursive_directory_iterator into the shared _Dir_stack object. Because _Dir_stack is an opaque type, the member functions that access the _M_options and _M_pending variables cannot be inline. Move them into the library. As a drive-by fix, add noexcept to the non-throwing member functions of recursive_directory_iterator. * config/abi/pre/gnu.ver: Export new symbols. * include/bits/fs_dir.h (recursive_directory_iterator::options()) (recursive_directory_iterator::recursion_pending()) (recursive_directory_iterator::disable_recursion_pending()): Remove inline definitions. Make noexcept. (recursive_directory_iterator::depth()) (recursive_directory_iterator::operator*()) (recursive_directory_iterator::operator->()): Make noexcept. (recursive_directory_iterator::_M_options) (recursive_directory_iterator::_M_pending): Remove data members. * src/c++17/fs_path.cc (_Dir_stack): Add constructor and data members. (recursive_directory_iterator::recursive_directory_iterator): Remove ctor-initializer. Use new constructor for _Dir_stack. (recursive_directory_iterator::options()) (recursive_directory_iterator::recursion_pending()) (recursive_directory_iterator::disable_recursion_pending()): Add non-inline definitions. (recursive_directory_iterator::depth()): Make noexcept. (recursive_directory_iterator::increment(error_code&)) (recursive_directory_iterator::pop(error_code&)): Adjust to new location of options and recursion_pending members. * testsuite/27_io/filesystem/iterators/recursion_pending.cc: New test. * testsuite/util/testsuite_fs.h (__gnu_test::scoped_file): Add user-declared move constructor and assignment operator, to make the type move-only.
