      Robot-related improvements based on feedback from Sid:
      
      	* event/sched/event-sched.h, event/sched/event-sched.c,
      	event/sched/rpc.h, event/sched/rpc.cc: Send a notification of the
      	start of event time and timelines.  Add a '-r' option that forces
      	it to use the default rpc path (so dan can use a custom
      	scheduler/rmcd/etc on ops).
      
      	* robots/GNUmakefile.in, robots/emc/GNUmakefile.in,
      	robots/mtp/GNUmakefile.in, robots/primotion/GNUmakefile.in,
      	robots/rmcd/GNUmakefile.in, robots/vmcd/GNUmakefile.in,
      	robots/tbsetdest/tbsetdest.cc: Add a control-install target.
      
      	* robots/primotion/garcia-pilot.cc: Take out some experimental
      	code.
      
      	* robots/primotion/dashboard.hh, robots/primotion/dashboard.cc,
      	robots/primotion/pilotClient.cc, robots/primotion/wheelManager.hh,
      	robots/primotion/wheelManager.cc: When doing a COMMAND_STOP, make
      	sure we only send one update packet, an idle or an abort.  Also
      	send back the actual distance travelled/pivoted.
      
      	* robots/tbsetdest/tbsetdest.cc: Don't output setdest event's with
      	a speed of zero.
      
      	* tbsetup/eventsys_control.in: When replaying/stopping, clear the
      	start of event time for the experiment.
      
      	* tbsetup/power_mail.pm.in: Decrease the threshold used to tell if
      	a node has been power cycled "recently".
      
      	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/sim.tcl.in: Bah, backout
      	last change, orientation is supposed to be in degrees at these
      	points.  Also, when automatically picking the sync server, don't
      	use nodes that are subnodes.
      
      	* tmcd/common/bootsubnodes: Send an ISUP for motes.
      
      	* www/moteleds.php3: Show the mote node names instead of the
      	robots.
      
      	* www/powertime.php3: Add option to mark nodes as powered off.
      
      	* www/robotmap.php3: Display the elapsed time for the overall
      	event time and for each active timeline.
      
      	* www/showexp.php3: Only display the blinky lights menu item when
      	there are motes.
      
      	* www/shownode.php3: Change "Update Power Time" -> "Update Power
      	State".
      
      	* www/tutorial/mobilewireless.php3: Fix some nits.
      
      	* xmlrpc/emulabserver.py.in: Add event_time_start method for
      	storing/getting/clearing the start of event time for an
      	experiment/timeline.

      Some more robot integration.
      
      	* event/lib/event.h, event/lib/event.c: Add some
      	event_notification creation functions that get used in
      	event-sched.
      
      	* event/sched/event-sched.c, event/sched/rpc.h,
      	event/sched/rpc.cc: Sync the start of event time with the
      	robots reaching their initial positions.  This is done by
      	creating a master event-sequence that takes care of sending
      	the SETDEST events and then starting the Simulator timeline.
      
      	* mote/tbuisp.in: Use node_reboot instead of ssh'ing in.
      
      	* robots/GNUmakefile.in: Don't build tbsetdest if ulsshxmlrpcpp is
      	not available.
      
      	* robots/emc/loclistener.in: Clear the destination values for a
      	node when it reaches its destination.
      
      	* robots/primotion/garcia-pilot.cc,
      	robots/primotion/pilotClient.cc: Some cleanup and debugging.
      
      	* robots/primotion/wheelManager.cc: Check the rear sensors for
      	obstructions and then decide which way to pivot.
      
      	* robots/rmcd/pilotConnection.h, robots/rmcd/pilotConnection.c,
      	robots/rmcd/rclip.h: Even more tweaking.
      
      	* robots/tbsetdest/tbsetdest.cc: Don't generate points that are
      	outside the camera bounds or inside an obstacle.
      
      	* robots/vmcd/visionTrack.c, robots/vmcd/vmcd.h,
      	robots/vmcd/vmcd.c:  Add more debugging output.
      
      	* tbsetup/os_setup.in: Removed the robot hack used when deciding
      	which nodes to reconfig/reboot.  Added a robot hack to avoid
      	rebooting a robot whose mote is being os_load'd, since it would
      	interrupt tbuisp which does the reboot anyways.  Also fixed a
      	small typo.
      
      	* tbsetup/ns2ir/node.tcl, tbsetup/ns2ir/sim.tcl.in: Oops, forgot
      	to convert degrees to radians.
      
      	* tbsetup/ns2ir/topography.tcl: When checking for node destination
      	points in obstacles, include the implicit exclusion zone.
      
      	* tmcd/common/bootsubnodes: Add empty "mote" case.
      
      	* tmcd/linux-sg/GNUmakefile.in: Make some of the /etc subdirs when
      	doing the install.
      
      	* tmcd/linux-sg/rc.stargate: Start garcia-pilot.
      
      	* vis/floormap.in: Add options for showing the camera bounds,
      	obstacle exclusion zones, and displaying vnames instead of pnames.
      
      	* www/ledpipe.php3: Finally figured out how to use a socket
      	instead of popening a perl script.
      
      	* www/robotmap.php3: Add checkboxes for displaying/not displaying
      	the camera bounds and obstacle exclusion zones.  Add a legend
      	showing what actual vs. destination points are.  Pass pid/eid
      	through to vis/floormap if it is given.
      
      	* www/showexp.php3: Add a "Robot Map" link to experiments that
      	have allocated garcias.
      
      	* www/floormap/map_legend_node.gif,
      	www/floormap/map_legend_node_dst.gif: Icons used by the robot map
      	legend.
      
      	* www/floormap/robots-4.jpg: Added an obstacle around the entryway
      	so people are slightly less likely to trip over the robots.  Added
      	a coordinate system legend to the top left corner.
      
      	* www/tutorial/mobilewireless.php3: Add links to David's movie of
      	the robot making its way around the pillar.
      
      	* www/tutorial/robot_anim.gif: A nifty gifanim clip of the robot
      	movie.
      
      	* xmlrpc/emulabserver.py.in: Pull the camera data from the DB,
      	instead of returning hardcoded stuff.

      Tweaks to robot display: · 3acfb53d
      Leigh B. Stoller authored
      * If there is a destination for a rebot, display that as a shadow circle.
        Draw a light grey line from source to destination.
      
      * If an orientation is in the location_info table, the current location
        circle gets a stick drawn in that direction.
      
      * If the destination has an orientation in the nodes table, the shadow
        circle gets a stick drawn in that direction.
      
      * I added a little bit of code so that labels are drawn on top if the
        orientation stick would draw through it. I'm sure that will interact with
        cropping badly if a node is right at the edge of the picture.

      Here is a checkpoint of the admission control stuff I have been working on. · 54f55585
      Leigh B. Stoller authored
      The last part is the stuff to hook it in from assign_wrapper, and some
      additional support in assign that Rob is adding for me. This comment is
      from the top of new file db/libadminctrl.pm.in and describes everything in
      detail.
      
      # Admission control policies. These are the ones I could think of, although
      # not all of these are implemented.
      #
      #  * Number of experiments per type/class (only one expt using robots).
      #
      #  * Number of experiments per project
      #  * Number of experiments per subgroup
      #  * Number of experiments per user
      #
      #  * Number of nodes per project      (nodes really means pc testnodes)
      #  * Number of nodes per subgroup
      #  * Number of nodes per user
      #
      #  * Number of nodes of a class per project
      #  * Number of nodes of a class per group
      #  * Number of nodes of a class per user
      #
      #  * Number of nodes of a type per project
      #  * Number of nodes of a type per group
      #  * Number of nodes of a type per user
      #
      #  * Number of nodes with attribute(s) per project
      #  * Number of nodes with attribute(s) per group
      #  * Number of nodes with attribute(s) per user
      #
      # So we have group (pid/gid) policies and user policies. These are stored
      # into two different tables, group_policies and user_policies, indexed in
      # the obvious manner. Each row of the table defines a count (experiments,
      # nodes, etc) and a type of thing being counted (experiments, nodes, types,
      # classes, etc). When we test for admission, we look for each matching row
      # and test each condition. All conditions must pass. No conditions means a
      # pass. There is also some "auxdata" which holds extra information needed
      # for the policy (say, the type of node being restricted).
      #
      #      uid:     a uid
      #   policy:     'experiments', 'nodes', 'type', 'class', 'attribute'
      #    count:     a number
      #  auxdata:     a string (optional)
      #
      # Example: A user policy of ('mike', 'nodes', 10) says that poor mike is
      # not allowed to have more 10 nodes at a time, while ('mike', 'type',
      # '10', 'pc850') says that mike cannot allocate more than 10 pc850s.
      #
      # The group_policies table:
      #
      #      pid:     a pid
      #      gid:     a gid
      #   policy:     'experiments', 'nodes', 'type', 'class', 'attribute'
      #    count:     a number
      #  auxdata:     a string (optional)
      #
      # Example: A project policy of ('testbed', 'testbed', 'experiments', 10)
      # says that the testbed project may not have more then 10 experiments
      # swapped in at a time, while ('testbed', 'TG1', 'nodes', 10) says that the
      # TG1 subgroup of the testbed project may not use more than 10 nodes at
      # time.
      #
      # In addition to group and user policies (which are policies that apply to
      # specific users/projects/subgroups), we also need policies that apply to
      # all users/projects/subgroups (ie: do not want to specify a particular
      # restriction for every user!). To indicate such a policy, we use a special
      # tag in the tables (for the user or pid/gid):
      #
      #      '+'  -  The policy applies to all users (or project/groups).
      #
      # Example: ('+','experiments',10) says that no user may have more then 10
      # experiments swapped in at a time. The rule overrides anything more
      # specific (say a particular user is restricted to 20 experiments; the above
      # rule overrides that and the user (all users) is restricted to 10.
      #
      # Sometimes, you want one of these special rules to apply to everyone, but
      # *allow* it to be overridden by a more specific rule. For that we use:
      #
      #      '-'  -  The policy applies to all users (or project/groups),
      #              but can be overridden by a more specific rule.
      #
      # Example: The rules:
      #
      #	('-','type',0, 'garcia')
      #       ('testbed', 'testbed', 'type', 10, 'garcia')
      #
      # says that no one is allowed to allocate garcias, unless there is specific
      # rule that allows it; in this case the testbed project can allocate them.
      #
      # There are other global policies we would like to enforce. For example,
      # "only one experiment can be using the robot testbed." Encoding this kind
      # of policy is harder, and leads down a path that can get arbitrarily
      # complex. Tha path leads to ruination, and so we want to avoid it at
      # all costs.
      #
      # Instead we define a simple global policies table that applies to all
      # experiments currently active on the testbed:
      #
      #   policy:     'nodes', 'type', 'class', 'attribute'
      #     test:     'max', others I cannot think of right now ...
      #    count:     a number
      #  auxdata:     a string
      #
      # Example: A global policy of ('nodes', 'max', 10, '') say that the maximum
      # number of nodes that may be allocated across the testbed is 10. Thats not
      # a very realistic policy of course, but ('type', 'max', 1, 'garcia') says
      # that a max of one garcia can be allocated across the testbed, which
      # effectively means only one experiment will be able to use them at once.
      # This is of course very weak, but I want to step back and give it some
      # more thought before I redo this part.
      #
      # Is that clear? Hope so, cause it gets more complicated. Some admission
      # control tests can be done early in the swap phase, before we really do
      # anything (before assign_wrapper). Others (type and class) tests cannot
      # be done here; only assign can figure out how an experiment is going to map
      # to physical nodes (remember virtual types too), and in that case we need
      # to tell assign what the "constraints" are and let it figure out what is
      # possible.
      #
      # So, in addition to the simple checks we can do, we also generate an array
      # to return to assign_wrapper with the maximum counts of each node type and
      # class that is limited by the policies. assign_wrapper will dump those
      # values into the ptop file so that assign can enforce those maximum values
      # regardless of what hardware is actually available to use. As per discussion
      # with Rob, that will look like:
      #
      #	set-type-limit <type> <limit>
      #
      # and assign will spit out a new type of violation that assign_wrapper will
      # parse.
      #
      # NOTES:
      #
      #  1) Admission control is skipped in admin mode; returns okay.
      #  2) Admission control is skipped when the pid is emulab-ops; returns okay.
      #  3) When calculating current usage, nodes reserved to emulab-ops are
      #     ignored.
      #  4) The sitevar "swap/use_admission_control" controls the use of admission
      #     control; defaults to 1 (on).
      #  5) The current policies can be viewed in the web interface. See
      #     https://www.emulab.net/showpolicies.php3
      #  6) The global policy stuff is weak. I plan to step back and think about it
      #     some more before redoing it, but it will tide us over for now.
