      Changes necessary for moving most of the stuff in the node_types · 624a0364
      Leigh B. Stoller authored
      table, into a new table called node_type_attributes, which is intended
      to be a more extensible way of describing nodes.
      
      The only things left in the node_types table will be type,class and the
      various isXXX boolean flags, since we use those in numerous joins all over
      the system (ie: when discriminating amongst nodes).
      
      For the most part, all of that other stuff is rarely used, or used in
      contexts where the information is needed, but not for type descrimination.
      Still, it made for a lot of queries to change!
      
      Along the way I added a NodeType library module that represents the type
      info as a perl object. I also beefed up the existing Node module, and
      started using it in more places. I also added an Interfaces module, but I
      have not done much with that yet.
      
      I have not yet removed all the slots from the node_types table; I plan to
      run the new code for a few days and then remove the slots.
      
      Example using the new NodeType object:
      
      	use NodeType;
      
      	my $typeinfo = NodeType->Lookup($type);
      
              if ($typeinfo->control_interface(\$control_iface) ||
                  !$control_iface) {
        	    warn "No control interface for $type is defined in the DB!\n";
              }
      
      or using the Node:
      
      	use Node;
      
              my $nodeobject = Node->Lookup($node_id);
              my $imageable  = $nodeobject->NodeTypeInfo()->imageable();
      or
              my $rebootable = $nodeobject->isrebootable();
      or
              $nodeobject->NodeTypeAttribute("control_interface", \$control_iface);
      
      Lots of way to accomplish the same thing, but the main point is that the
      Node is able to override the NodeType (if it wants to), which I think is
      necessary for flexibly describing one/two of a kind things like switches, etc.

      Add new table, node_type_attributes, which will eventually encompass · 9bcb29bb
      Leigh B. Stoller authored
      most of what is in the node_types table (and node_types_auxtypes).
      The goal is to make most of the type information free form key/value
      pairs so that type information is more extensible.
      
      This commit simply creates the table and populates it with initial
      info using init_nodeattrs.pl. I expect this script to change, but it
      can be rerun later so no big deal.

      Many changes to tblog code.  Database update needed:
      
      1) Added summary of failed nodes is os_setup.  The cause of the error is now
      classified as "user" if it is only user images that failed and the user
      image failed on every pc of a particular type.  Otherwise I leave the cause
      as "unknown" since it is really hard to tell what the real cause is.
      
      2) Raised the confidence threshold for most errors so that they will appear
      on the top.
      
      3) Added a special error when an experiment is canceled.  The cause is
      "canceled" and testbed-ops won't see these errors.
      
      4) Fixed a bug in assign_wrapper where it will incorrectly report "This
      experiment cannot be instantiated on this testbed..." when really the user
      canceled the swapin.
      
      5) Fixed a bug where os_setup errors where being incorrectly reported as
      assign errors.  This happens when os_setup fails for some reason and
      tbswap tries again, but the second time around there are not enough nodes.
      So the last error is coming from assign even though the true cause of the
      error is due to failed nodes.  The fix for this involved added a new column
      to the log table, "attempt", which will be 1 for the first attempt and then
      incremented for each new attempt.  tblog_find_error will then simply ignore
      any errors with "attempt > 1".
      
      6) Also fixed a potential problem when there is an error during the cleanup
      phase by adding another column "cleanup".  tblog_find_error will
      also ignore any errors with the cleanup bit set.

      Framework for supporting 802.1q tagged VLANs as a form of multiplexed link. · 3f1c15e2
      Mike Hibler authored
      Actually, most of the changes here were just to generalize the "virtual
      interface" state in the DB.  Other than the client-side scripts, there
      is very little specific here specific to tagged VLANs.
      
      In fact, you cannot specify "vlan" as a type yet as we haven't done the
      snmpit support for setting up the switches.
      
      For more info see bas:~mike/flux/doc/testbed-virtinterfaces.txt, which I
      will integrate into the knowledge base and the Emulab doc at some point.

      The template "datastore" ... · fe9aa6a4
      Leigh B. Stoller authored
      Each template has a datastore, which is really just a subdirectory that can
      be populated with files, and committed to the subversion archive.  Note,
      the datastore os specific to the template itself. The Template Archive link
      on the Show Template page takes you to the subdirectory, which by
      convention I am calling "datastore".
      
      The directory actually lives in /proj/pid/exp/eid/TGUID-VERS ... but that
      path is printed out for you on the archive page.
      
      Anyway, put stuff in the datastore directory, and then commit the template
      archive so there is a tag associated with it.
      
      When an instance is created, a checkout of the datastore is placed in the
      experiment directory (/proj/pid/eid/exp/template_datastore). The current
      tag (from above) is stored with the instance so that we can later recreate
      the enviroment for the instance, say for rerun.
      
      Tarfiles and rpms in the datastore can be referenced as xxx://foo.rpm (in
      your NS file).  tarfiles_setup transforms those when the instance is
      swapped in, sorta like it does other URLs, only it does not actually fetch
      them, just need to rewrite the paths so they reference datastore.
      
      The program agent gets another environment variable so you can refer to the
      datastore without hardwiring paths ($DATASTORE). Eventually I want to move
      the checkout someplace else, but it was easy to drop it into the experiment
      directory for now.

      Address a number of issues raised by Mike. The most notable: · 4d663bb8
      Leigh B. Stoller authored
      * Rework metadata to be somewhat more general so that they can be used for
        things like parameter descriptions.
      
      * My own little part of javascript hell ... add a highlight around the
        "current" template in the template graph. Sheesh!
      
      * Add more tooltips (using the tooltip library). When you mouseover the
        metadata or descriptions, the formatted text is shown in a tooltip,
        which is handy when the valus is truncated cause its too long for the
        tables.

      More experiment run stuff. Also the NS file parsing support that was · 74bf8d1d

      needed (reparsing of NS file with current bindings).
      
      Mostly I decided that I made a huge mistake in using the exptidx as the
      main cross index. I started to change that, which took a bunch of time.
      Still more tables to fix up, but I think all of this code is gonna need
      a major reorg once I am no longer under the gun to get it done.

      Changed format of email sent to user on errors.  The error will now
      appear instead of the generic message when I am confident it is
      accurate.  The subject line will also change to reflect the cause of
      an error.
      
      Avoid sending mail to testbed-ops during failed swap related evenets
      in some cases.  It will instead be sent to a new mailing list
      testbed-errors.
      
      Added a new row in the experiment info table "Last Error:" which
      states the cause of the error, and links to a new page displaying the
      error.
      
      Made some assign/assign_wrapper errors more informative.
      
      The error (as determined by tblog) is now stored in the database in a
      more structured fashion.  This inlcudes adding a column for the session
      (in the log table) to testbed_stats to link eash swap event with the
      logs and possible the error.
