  • Date: 2008-08-02 10:48:24 UTC
  • Revision ID: teddy@fukt.bsnet.se-20080802104824-fx0miwp9o4g9r31e
* plugbasedclient.c (struct process): New fields "eof", "completed",
                                      and "status".
  (handle_sigchld): New function.
  (main): Initialize "dir" to NULL to only closedir() it if necessary.
          Move "process_list" to be a global variable to be accessible
          by "handle_sigchld".  Make "handle_sigchld" handle SIGCHLD.
          Remove redundant check for NULL "dir".  Free "filename" when
          no longer used.  Block SIGCHLD around fork()/exec().
          Restore normal signals in child.  Only loop while running
          processes exist.  Print process buffer when the process is
          done and it has emitted EOF, not when it only emits EOF.
          Remove processes from list which exit non-cleanly.  In
          cleaning up, closedir() if necessary.  Bug fix: set next
          pointer correctly when freeing process list.

* plugins.d/passprompt.c (main): Do not ignore SIGQUIT.
