[Queue-developers] new intermediate development Queue version

[QingLong <Qin...@bo...>]

	Hello!

   I've commited a few changes (3 bugfixes and 1 improvement/bugfix)
 to queue-development at sourceforge. ChangeLog notes follow:

      Made queued (handle.c) correctly assemble full path
      if the command is specified as relative path (./xxx or ../xxx).
      Also fixed a bug I have recently introduced in this same piece of code.

      Added a few trace messages (activated by --debug or --verbose).

      Fix: Made queue (queue.c) request loadaverage from remote host
      before trying to submit a job to it, if the host was explicitly
      specified on command line (-h or -H). This is necessary,
      as that host can turn out not to be running the given queue,
      if this is the case the submitted job will hang or sleep forever.

      Fix: (startjob() queued.c): a file for stdout redirection
      has been opened twice (thus, creating two fd's), once via creat(),
      and another time via open(). Although I fail to understand why
      it is so necessary to do the job twice, I added close() after creat()
      to make it work in accordance with comments (open fd 1 for /*stdout*/,
      and dup() it to fd 2 (rather than 3) for /*stderr*/).

      Changed QueueD behaviour in case of receiving a job on inactive queue.
      Made it just abort conection silently (queued.c check_query()).
      The queue protocol should have some way to return some error status
      indicator (and a descriptive error message) to client
      and to abort connection gracefully if client tries to do something
      unreasobnable or prohibited.

 Please give it a try.

   Thank you.

      QingLong.
