ntpath._readlink_deep(), the fallbackrealpath()uses for a link Windows cannot open, now resolves the directory that contains the link with_getfinalpathname()before joining a relative target to it, so..in the target goes up from the real directory. It keeps the textual join only if that directory cannot be resolved with one of the error codes the function already tolerates. Two expectations intest_realpath_broken_symlinkschange (broken2andbroken3now resolve toABSTFN\missing), because they asserted the unresolved join.I could not run this on Windows: the changed branch and the
test_ntpathtests are skipped on Linux, where I only exercised the code over stand-ins for thentfunctions. It needs the Windows CI run before review.test_parent_symlink3intest_tarfilepasses on Linux with and without the change; its Windows branch is the one that depends on it.Fixes #160506
