This lets Emacs deal with arbitrary local symlinks without mishandling their contents (Bug#28156). For example, (progn (shell-command "ln -fs '~' 'x'") (rename-file "x" "/tmp/x")) now consistently creates a symbolic link from '/tmp/x' to '~'. Formerly, it did that only if the working directory was on the same filesystem as /tmp; otherwise, it expanded the '~' to the user's home directory. * lisp/dired.el (dired-get-filename): Use files--name-absolute-system-p instead of rolling our own code. * lisp/files.el (files--name-absolute-system-p): New function. (file-truename, file-chase-links): Use it to avoid mishandling symlink contents that begin with ~. (copy-directory, move-file-to-trash): Use concat rather than expand-file-name, to avoid mishandling symlink contents that begin with ~. * src/fileio.c (Fmake_symbolic_link): Do not expand leading "~" in the target unless interactive. Strip leading "/:" if interactive. (emacs_readlinkat): Do not prepend "/:" to the link target if it starts with "/" and contains ":" before NUL. * test/src/fileio-tests.el (try-link): Rename from try-char, and accept a string instead of a char. All uses changed. (fileio-tests--symlink-failure): Also test leading ~, and "/:", to test the new behavior. |
