should start with. Currently 'emulab' or 'plab', defaults to emulab.

in the dev tree. I'm tired of problems on the mini that wastes
my time.

Changes include 2 new tmcd commands: tmcc routelist returns
the routes for all the vnodes hosted on a pnode. tmcc role
returns the role of a reserved node, like 'virthost' or
'simhost.  tmcc ifconfig now reports an RTABID field which
is calculated in assign wrapper. All the new changes
in assign wrapper will be checked in after I finish testing.

All the DB changes are in: simnode_capacity in node_types, rtabid in
interfaces and veth_interfaces. New NSE event_objtype and NSEEVENT
event_eventtype. Changed the erole field in the reserved table
to have 'simhost' instead of 'simnode'. Changed the correspoding
libdb subroutines.

to get a list of what types a project is allowed to use.

physical plab nodes.

for various table/columns pairs. Used by php/perl libraries
to check data values to make sure they are valid. Note that
the intent is not to check whats valid to stick in the DB,
but what our conventions regard as valid (exampe: a uid is
2-8 chars, alphanumeric, starts with an alpha).

devel tree, gives the user a special view of the web pages.

trivial simulated links. This is coz existing sim node support that
goes on 1 pnode can't handle this. Also added a 'sim' type in the
node_types table and a issimnode column in it.

Now, the old sim node support is working and demoable.

for tracking login attacks.

work; do not run it yet since the rest of the support is not in place.

this directory called initkey.pl to generate them for existing
experiments. I will run this script when the rest of the work is done.

but its nice to have it in the DB too so that we do not have to read
that file!

multiple desires for each vnode.

into assign.

server.

entry to database-migrate.sql that I forgot with my last commit.

but it's per node, not per type. Will initially be used to store
inforomation about planetlab nodes.

node_types table. This should make it easier to assign last mile
types to widearea nodes since a given type can now have as many
subtypes as you like.

Also add cpu_usage and mem_usage to the experiments table. The
user will be able to specify these in the NS file. Currently a
tinyint, where the default is zero, which means ignore.

that should be associated with a node when it is put into the ptop
file.

as an admin if you go to a users moduserinfo page. I'll be using this
to flag accounts frozen due to email problems.

revision.

have to change to an int format to save space. I'll probably make some
changes to the migrate code later, but I want to get the DB changes
checked in.

       control_iface join with node_types, since new nodes have more
       than just expt and ctrl interfaces (ixps). The control_net slot
       is bogus anyway. Note that 'jail' is a placeholder for later.
       A 'fake' interface is not to be confused with veth interfaces; it
       is a psuedo interface like that found between an ixp and the host.

       alter table interfaces add \
		role enum('ctrl', 'expt', 'jail', 'fake', 'other') \
		NOT NULL default 'other' after iface;

(soon to be working) sync server. When non-null (set by parser) that
node will start a sync server and other nodes will know to use it.
Returned by tmcd of course.

not have to wait 3 minutes for it to finish before he can watch his
experiment swapin fail for some other reason.

I adopted the same pid mechanism as in eventsys_control.in, which uses
a slot in the experiments table.

Running "prerender" puts the render into the background and stores
the pid. Running "prerender -r" kills a running prerender and removes
the existing info from the DB.

Fixed the problem with swapmod not restoring the old vis; swapmod now
kills any running prerender, and restarts one if the swapmod fails
(the prerun of the new NS file starts up another prerender in the
background).

Add setpriority() call in prerender to nice it and children to 15.

       being used in an experiment (node, virthost, delaynode,
       simnode). This is for helping to simplify the swapmod code
       support in assign, and to eventually fix the delaynode problem.

final time, so that we can see how long things take. As per Jay's
request.
