Jamie Landeg-Jones fefb3c46a8 diff: fix incorrectly displaying files as duplicates ... When diff hits certain access errors, function diffreg() shows the error message, and then returns to the calling function, which calls print_status() with the return value. However, in these cases, the return value isn't changed from the initial default value of D_SAME. Normally, print_status() with a value of D_SAME does nothing, so this works out ok, however, if the "-s" flag is set, a message is displayed showing identicality: case D_SAME: if (sflag) printf("Files %s%s and %s%s are identical\n", path1, entry, path2, entry); break; This then produces such results as: % diff -s /COPYRIGHT /var/run/rpcbind.sock diff: /var/run/rpcbind.sock: Operation not supported Files /COPYRIGHT and /var/run/rpcbind.sock are identical % diff -s /COPYRIGHT /etc/master.passwd diff: /etc/master.passwd: Permission denied Files /COPYRIGHT and /etc/master.passwd are identical Create a D_ERROR status which is returned in such cases, and print_status() then deals with that status seperately from D_SAME PR: 252614 MFC after: 1 week		2021-01-25 20:38:18 +01:00
