Paul Eggert 01c885f21f Fix race with rename-file etc. with dir NEWNAME ... This changes the behavior of rename-file etc. slightly. The old behavior mostly disagreed with the documentation, and had a race condition bug that could allow attackers to modify victims' write-protected directories (Bug#27986). * doc/lispref/files.texi (Changing Files): Document that in rename-file etc., NEWFILE is special if it is a directory name. * etc/NEWS: Document the change in behavior. * src/fileio.c (directory_like): Remove. All uses removed. (expand_cp_target): Test only whether NEWNAME is a directory name, not whether it is currently a directory. This avoids a race. (Fcopy_file, Frename_file, Fadd_name_to_file, Fmake_symbolic_link): Document behavior if NEWNAME is a directory name. (Frename_file): Simplify now that the destdir behavior occurs only when NEWNAME is a directory name. * test/lisp/net/tramp-tests.el (tramp-test11-copy-file) (tramp-test12-rename-file, tramp--test-check-files): Adjust tests to match new behavior.		2017-09-10 15:46:51 -07:00
