Fixee: /usr/src/cmd/ucbmail/edit.c in 4.1bsd; .../edit.c in 4.2bsd Challenge: When the 'e' and 'v' commands are used, mail tries to create a temporary file in the current working directory. If there's no write permission in the directory, things grind to a halt. Repeat by: echo This is a test | mail $user mkdir phony chmod 555 phony chdir phony mail e 1 q chdir .. rm -f -r phony and note the "Message1: Permission denied" diagnostic you get. Fix: Put the temporary file in the user's home directory. Here are the relevant lines from "edit.c": . . . #ifdef OLDVERSION char edname[15], nbuf[10]; #else char edname[PATHSIZE + 16], nbuf[10]; #endif . . . #ifdef OLDVERSION cp2 = copy("Message", edname); #else cp2 = copy(homedir, edname); cp2 = copy("/Message", cp2); #endif . . . -- ...decvax!seismo!umcp-cs!elsie!ado (301) 496-5688 (DEC, VAX and Elsie are Digital Equipment Corp. and Borden's trademarks)
