Add logfile_open flag to be used with spewlogfile to determine when
a logfile is active.

REPLACE statements will work correctly.

Also, remove the few INSERT statements, which will shortly be in
a new file.

commands to fill a few tables that should be common across most
sites, so that this data can be distributed to them.

The simple single-column table exported_tables controls which tables
are output.

information about which inter-switch links VLANs use, so that snmpit
does not have to re-calculate these paths.

indicating when the image was last updated. This gets updated by
create_image .

The hope is that it will give us some idea of which revision of
our standard images custom images are based off of.

Add idle_ignore column to db. Makes idlecheck completely ignore it when looking for idle expts. Unswappable expts still get checked and possibly harassed if they go idle.

want to report switch activity since a certain time (say, experiment
swapin.)

and last_swap_req) track the count and last time a request was sent.

The counters all get reset by idlecheck every time it runs unless it
detects you as inactive. Then when you go to send a swap request, it
will show you the info about how many have been sent and when the last
one was, and will let you know if the swap request will also go to the
proj leader if you send it. When you send the request, the email
mentions how many reminders you've been sent already, and only gets
cc'd to proj head on the third message (or more). Then it updates the
count and the timestamp of the last request sent.

create images from/for each node type. I'm gonna use this in the
newimage forms to control the list of node types.

a temp measure. See tmcd.c and node_update for usage of this variable.

user changes his personal info. This is intended to act as a serial
number when nodes ask for account info, but is also useful for
auditing.

node status.

with tb-set-wasolver-weights.

Add indexes by mac to interfaces and iface_counters, and node_id index to the latter as well. Speeds up idlecheck from 10-15 seconds to 1-2 seconds.

period over which the data was collected.

detects that at least one of the nodes in the lan includes a remote
node. Of course, on links can include remote nodes, but thats okay.

size. Works nicely!

Controls whether we user recent or hysterical widearea_delays data.
Defaults to 0.

remote nodes so that we do not overlap between experiments.

version of the data in widearea_delays . Schema for the two are
identical.

Also cleaned up the schema for both tables, so that they have proper
primary keys, etc.

in the NS file in one of two ways:

$ns cost $nodeA $nodeB 2
or
$link0 cost 3
(The latter form can also be used for LANs)

This information is stored in the database in the cost column of the
virt_lans table.  It's important to note that cost data is _not_
divided between the two sides of the link, as things like delay and
rdelay are. Since there are no physical devices (ie.  delay nodes)
node that this configuration needs to be split up between, doing so
would just be unnecessary work.

rough estimate of the bandwidth between each pair of nodes, and is
in kilobits per second.

interface should be configured to. Another possibility (and one we may
switch to) is to add the IP to the interfaces table so it gets
returned in the normal ifconfig, but thats going to require a number
of cascading changes that I do not want to deal with yet.

tunnels need to be created on each node; will be returned as a new
tmcd command.

Add nodeipportnum table, which is a hacky way to allocate non
overlapping port numbers on physical nodes (when multiple virtual
nodes are mapped to them). Used in assign_wrapper as a post pass over
the trafgens table and the tunnels table.

Add target_vname to virt_trafgens table as an aid in post passing.

allow us to (eventually) use trafgens on nodes with more than one
link, but more importantly, solves an immediate problem for ron nodes;
a lack of hostname translation.

iface_counters.
