Implement the proposed semantics from P1164R0, which reverts the changes of LWG 2935. This means that failure to create a directory because a non-directory already exists with that name will be reported as an error. While rewriting the function, also fix PR 87846, which is a result of the C++17 changes to how a trailing slash on a path affects the last component of a path. PR libstdc++/86910 PR libstdc++/87846 * src/filesystem/ops.cc (experimental::create_directories): Report an error when the path resolves to an existing non-directory (P1164). * src/filesystem/std-ops.cc (create_directories): Likewise. Handle empty filenames due to trailing slashes. * testsuite/27_io/filesystem/operations/create_directories.cc: Test when some component of the path exists and is not a directory. Test trailing slashes. * testsuite/experimental/filesystem/operations/create_directories.cc: Likewise. From-SVN: r266598 |
