Previously the logic that turned "a/b/c/../.." into "a/" failed to preserve an empty path at the end of the iteration sequence, as required by the trailing slash. That meant the result didn't meet the class invariants, and that "a/b/c/d/../../.." would remove four components instead of the three that "../../.." should remove. PR libstdc++/87116 * src/filesystem/std-path.cc (path::lexically_normal): When handling a dot-dot filename, preserve an empty final component in the iteration sequence. [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Use preferred-separator for root-directory. * testsuite/27_io/filesystem/path/generation/normal.cc: Add new tests for more than two adjacent dot-dot filenames. [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Replace slashes with preferred-separator in expected normalized strings. From-SVN: r263922 |
