      Add autoconf variable to control use of SelfLoader. · da55641a
      Mike Hibler authored
      This is a fer-now hack.  Perl 5.10 has issues with bogus taint check
      triggers that appear quite often when using the SelfLoader.  Now if you put:
          SELFLOADER_DATA=""
      In your defs-* file, it will disable the uses that cause problems.  Yes,
      the configure script should figure out if this is needed for you, but...
      another time.

      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).

      Changes for speeding up elabinelab server setup. · 6feda7d3
      Mike Hibler authored
      Boss/ops/fs: reboot them together after setup rather than serially.
      
      Nodes: leave them in PXEWAIT throughout the setup, until after boss has
      been rebooted.  At that point we send them the new bootinfo RESTART command
      telling pxeboot to re-DHCP and use the new info obtained (next-server) to
      contact a potentially new boss node.  This is a quick way to switch a node
      in PXEWAIT from talking to the outer boss to talking to the inner one.
      
      A significant number of rinky-dink changes were needed to do this, primarily
      adding a new state, PXELIMBO, where nodes can be sent to sit until they are
      restarted.  It turns out, just putting them in an existing state such as
      PXEWAKEUP or SHUTDOWN wouldn't work, as they tend to timeout or otherwise
      reboot.

      Finish up user deletion. The big visible change is that when a user is · 2965922b
      Leigh B Stoller authored
      deleted, they still remain in the user table with a status of
      "archived", but since all the queries in the system now use uid_idx
      instead of uid, it is safe to reuse a uid since they are no longer
      ambiguous. 
      
      The reason for not deleting users from the users table is so that the
      stats records can refer to the original record (who was that person
      named "mike"). This is very handy and worth the additional effort it
      has taken.
      
      There is no way to ressurect a user, but it would not be hard to add.

      New approach to dealing with nodes that fail to boot is os_setup, and · 5cf6aad2
      Leigh B. Stoller authored
      land in hwdown.
      
      Currently, if a node fails to boot in os_setup and the node is running
      a system image, it is moved into hwdown. 99% of the time this is
      wasted work; the node did not fail for hardware reasons, but for some
      other reason that is transient.
      
      The new approach is to move the node into another holding experiment,
      emulab-ops/hwcheckup. The daemon watches that experiment, and nodes
      that land in it are freshly reloaded with the default image and
      rebooted. If the node reboots okay after reload, it is released back
      into the free pool. If it fails any part of the reload/reboot, it is
      officially moved into hwdown.
      
      Another possible use; if you have a suspect node, you go wiggle some
      hardware, and instead of releasing it into the free pool, you move it
      into hwcheckup, to see if it reloads/reboots. If not, it lands in
      hwdown again. Then you break out the hammer.
      
      Most of the changes in Node.pm, libdb.pm, and os_setup are
      organizational changes to make the code cleaner.

      Add the ability to load images on virtnodes. For now, we just overload · c6c57bc9
      David Johnson authored
      the tb-set-node-os command with a second optional argument; if that is
      present, the first arg is the child OS and the second is the parent OS.
      We add some new features in ptopgen (OS-parentOSname-childOSname) based
      off a new table that maps which child OSes can run on which parents, and
      the right desires get added to match.  We setup the reloads in os_setup
      along with the parents.  Also needed a new opmode, RELOAD-PCVM, to handle
      all this.
      
      For now, users only have to specify that their images can run on pcvms, a
      special hack for which type the images can run on.  This makes sense in
      general since there is no point conditionalizing childOS loading on
      hardware type at the moment, but rather on parentOS.  Hopefully this stuff
      wiill mostly work on shared nodes too, although we'll have to be more
      aggressive on the client side garbage collecting old frisbee'd images for
      long-lived shared hosts.

      Implemt FS#187 -- Show admin history of projects: · 8054f5f8
      Kevin Atkinson authored
        When a project is initially created a new mailing list is created,
        PROJ-admin@emulab.net.
      
        testbed-approval is subscribed to the list
      
        Several emails that originally went to testbed-approval now go to the
        mailing list instead.  The From, To, fields are basically the same
        with testbed-approval becoming PROJ-admin.  This means some mail
        is sent with a From PROJ-admin and Bcc the mailing list.  Note that
        some mail still goes to testbed-approval directly, in particular
        ones where there is no clear project involved, and when a project is
        denied.
      
        In addition notifications of approval status of new members is also
        sent to the list.  These emails use to only go to testbed-audit@.
      
        Currently All mail sent to PROJ-admin is also sent to testbed-audit
        (via a Bcc).  This means that some mail that didn't use to go to
        testbed-audit now does.

      Slight reorg of the Mysql interface code; move all the DBQuery* stuff · 5b2a255f
      Leigh B. Stoller authored
      into a new module called emdbi.pm, and reexport the symbol names back
      out. This allows me to import just the db interface code to the Geni
      modules I am writing, without having to drag in 4000 lines of other
      crap that is Emulab specific. This change is invisible to the Emulab
      code, although I did it without any perl exporter/importer magic
      incantations; did it the old fashioned way.
