The rest is fixing broken assumptions: get_reply() now skips over dbug messages in case stderr is joined, and handle_poll() has to deal with fdin == fdout. I haven't tried anything virtualized yet, but this appears to do the trick for simple local sockets. In one terminal, perhaps in a loop: socat UNIX-LISTEN:/tmp/foo EXEC:'stapsh -vvv' The -v flags are at your discretion. As is, this will keep all stderr local, but you can use "EXEC:'stapsh -vvv',stderr" to send that over the socket too. In another terminal: stap --remote unix:/tmp/foo ... et voila! -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
