      Work on an optimization to the perl code. Maybe you have noticed, but · 92f83e48
      Leigh B Stoller authored
      starting any one of our scripts can take a second or two. That time is
      spent including and compiling 10000s of thousands of lines of perl
      code, both from our libraries and from the perl libraries.
      Mostly this is just a maintenance thing; we just never thought about
      it much and we have a lot more code these days.
      So I have done two things.
      1) I have used SelfLoader() on some of our biggest perl modules.
         SelfLoader delays compilation until code is used. This is not as
         good as AutoLoader() though, and so I did it with just a few 
         modules (the biggest ones).
      2) Mostly I reorganized things:
        a) Split libdb into an EmulabConstants module and all the rest of
           the code, which is slowly getting phased out.
        b) Move little things around to avoid including libdb or Experiment
           (the biggest files).
        c) Change "use foo" in many places to a "require foo" in the
           function that actually uses that module. This was really a big
           win cause we have dozens of cases where we would include a
           module, but use it in only one place and typically not all.
      Most things are now starting up in 1/3 the time. I am hoping this will
      help to reduce the load spiking we see on boss, and also help with the
      upcoming Geni tutorial (which kill boss last time).

      A handy utility for tracing module inclusion and the amount of time it · d8230a46

      takes to include each module. Run like:
      boss> perl -I /usr/testbed/devel/stoller/lib -MTraceUse foo.pl

      Add disk_image tag when an OSID is specified for a ProtoGeni physical · b86b54b0
      Leigh B Stoller authored
      node. Currently this is rewritten to a disk_image tag in the
      emulab-ops project of the CM the node is allocated from. This works
      nicely for STD images since all Emulabs tend to have the same STD
      images, but will not work for localized images. All of this image
      stuff in cooked mode needs a bunch of work.
      Also add support for talking to non elvin-compat nodes on other CMs by
      having the event clients contact another pubsubd instance on the home
      boss, which will gateway the events back and forth, munging them as
