Currently the _Dir::open_subdir function decides whether to construct a _Dir_base with just a pathname, or a file descriptor and pathname. But that means it is tiughtly coupled to the implementation of _Dir_base::openat, which is what actually decides whether to use a file descriptor or not. If the derived class passes a file descriptor and filename, but the base class expects a full path and ignores the file descriptor, then recursive_directory_iterator cannot recurse. This change introduces a new type that provides the union of all the information available to the derived class (the full pathname, as well as a file descriptor for a directory and another pathname relative to that directory). This allows the derived class to be agnostic to how the base class will use that information. libstdc++-v3/ChangeLog: * src/c++17/fs_dir.cc (_Dir::dir_and_pathname):: Replace with current() returning _At_path. (_Dir::_Dir, _Dir::open_subdir, _Dir::do_unlink): Adjust. * src/filesystem/dir-common.h (_Dir_base::_At_path): New class. (_Dir_base::_Dir_Base, _Dir_base::openat): Use _At_path. * src/filesystem/dir.cc (_Dir::dir_and_pathname): Replace with current() returning _At_path. (_Dir::_Dir, _Dir::open_subdir): Adjust. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
