and ignore remote (i.e. mismatched URN) nodes, just as was done with UUIDs.

things can be built without trang), and install them so that assign
can find them when it needs them.

for very small loss values.

port speed and duplex when the switch does not support the stack mib.

1. Allow use of the shared nodes via the "exclusive" tag in the rspec.

2. Switch to using the mapper in GetTicket() and in RedeemTicket() as
   per this email I sent:

* GetTicket(): New rspec comes in and I build a virtual topology as I
 parse the rspec. Basically, virt_nodes and virt_lans table entries,
 which are stored into the DB. The rspec can include wildcards or
 specific nodes; I use the "fixed" slot of the virt_nodes table. Note
 that I am not yet handling fixed ifaces. Nice thing about this is
 that all of the show exp tools work.

 I run the (new) mapper on it in "solution" mode. This does two
 things; wildcards are mapped, and 2) it verifies that the rspec is
 mappable on the local hardware. Solution mode does not actually
 change the DB, but rather it spits out an XML file that I parse
 (note, we eventually will pass the rspec through, but I am not ready
 for that yet). I then allocate the nodes to the holding area, update
 the rspec, create a ticket, and return it.

* RedeemTicket(): I run the new mapper again, only this time in real
 mode with -update. This is basically a redo of the run above since
 all the nodes are reserved already, but the DB is actually filled
 out this time. I then create the slivers and such.

 The other difference is that instead of creating the vlans by hand,
 I can now run snmpit -t to do the work for me. Ditto for tear down
 with snmpit -r.

 Another bonus is that I can add (missing) IP addressess during the
 initial rspec parse, and the nodes now boot and have their
 interfaces configured. Virtual interfaces too, including the ones
 inside of virtual nodes.

* All of the above works with shared nodes too:

"<rspec xmlns=\"http://protogeni.net/resources/rspec/0.1\"> " +\
" <node virtual_id=\"geni1\" "+\
"       virtualization_type=\"emulab-vnode\" " +\
"       virtualization_subtype=\"emulab-openvz\" " +\
"       exclusive=\"0\"> " +\
"   <interface virtual_id=\"virt0\"/> " +\
" </node>" +\
" <node virtual_id=\"geni2\" "+\
"       virtualization_type=\"emulab-vnode\" " +\
"       virtualization_subtype=\"emulab-openvz\" " +\
"       exclusive=\"0\"> " +\
"   <interface virtual_id=\"virt0\"/> " +\
" </node>" +\
" <link virtual_id=\"link0\"> " +\
"  <interface_ref " +\
"            virtual_interface_id=\"virt0\" " +\
"            virtual_node_id=\"geni1\" " +\
"            /> " +\
"  <interface_ref " +\
"            virtual_interface_id=\"virt0\" " +\
"            virtual_node_id=\"geni2\" " +\
"            /> " +\
" </link> " +\
"</rspec>"

The shared nodes boot, and you can ping on the experimental networks.

Caveats:

* UpdateTicket and UpdateSliver need work as per the mail I sent the
 other day about the state of the sliver between the ticket and the
 sliver operations.

* Collocation specifications are ignored since we do not have any way
 to specify this to assign when wildcards are used. Rob, I am
 wondering if assign has any tricks we can take advantage of.

* Still need to commit all the snmpit changes and get that hooked into
 the CM.

CMs in the CH database. Only the CH can run this. Also, all it does is
collect the tickets.

This is returned to the CH via the ListTickets() CM method. Only the
CH can invoke this. This will hold us until I decide how I want to
keep the ClearingHouse history tables updated.

packing to favor nodes that already have vnodes on them. This can also
come from the node_attributes table.

Then I disabled these changes cause it was causing me problems; the
shared nodes were not getting picked. Needs more thought.

Add a solution option that is similar to impotent mode,
but spits out an xml file with the solution. Used by the CM.
A couple of little fixes.

slot of the virt_nodes years ago!

record that info in the DB.

to do for a container.

if there are no node_type elements, that means we should apply the default.

Now there is a 'ComponentView' which manages the node selection/combobox for several Component Managers.

Checkpoint. The flash demo now parses and uses URNs properly, uses the available tag for nodes, and parses the latest version of the rspec in advertisements. Note that Emulab has been set up as the only CM atm until we push out the new ptopgen to other sites.

were actually ready to be checked in so far.  Revert the rest for now.
Whoops.

CM URNs for links are now shown rather than UUIDs. Fixed bug in the 'available' tag which showed all local nodes as unavailable in rspecs. Fixed selection criteria so that all nodes are shown in an rspec rather than just the available ones.

updates which they have not applied.
