Big changes a comin' to try to get us back on the supported path.

 * perl 5.14 -> 5.20
 * mysql 5.1 -> 5.5
 * php 5.4   -> 5.6
 * tcl 8.4   -> 8.6
 * number of vim patches up to 683.

Not everything tested yet, but getting there.

Specific changes:

 * New install/ports directory. New packages for FreeBSD 10.1 are version
   6.1. Cleaned up the ports' Makefiles getting rid of conditionals for
   all older versions. Also got rid of ports we don't use. Old ports tree
   is now install/oports.

 * Install script changes. Make sure /usr/bin/perl and /usr/local/bin/python
   links exist. Ports no longer make these but we use them in '#!'. Changes
   to mysql install and startup script--mysql has changed a LOT since we did
   the support in 4.x. Create syslog entry for named.log. Make sure php.conf
   loads the legacy "mysql" module rather than using "mysqli".

 * Elabinelab support. reflect new packages, remove all old packages
   (except perl) before installing new versions, install "extras" package,
   make sure sendmail cert get regenerated, make sure /usr/bin/perl link
   exists, make sure /usr/local/bin/python link exists.

 * Custom ports. otcl and xerces-c2 have both been removed from the ports
   tree as of Q2 2015. ipmitool-devel is a port for the latest version of
   ipmitool. The FreeBSD port is still a rev behind here. We need the
   newer version as it appears to make our SOL consoles more stable.

 * Random. Fixed prerender as neato output has changed again. Tweak to
   sslxmlrpc_server to reflect change in an underlying library. Tweak to
   db/libdb.py.in to turn on autocommit which matters now as mysql 5.5 will
   hang on a metadata lock otherwise. Remade eventsys perl/python stubs
   with SWIG 2.0. SWIG 1.3 did not produce working stubs for perl 5.20.

Specific un-changes:

 * Apache is still at 2.2. I lack the guts and skilz to upgrade to 2.4.

 * Xerces library is still at (now unsupported) 2.8. Assign will need
   changes before we can move to 3.x.

 * Python is still 2.7.

Thanks to Keith Sklower for all the work he did converting ports!

tables were locked. Maybe we should block signals during this
time, typically we are signaled when cause the experiment is
being terminated or modified anyway.

This commit is intended to makes the license status of Emulab and
ProtoGENI source files more clear.  It replaces license symbols like
"EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
blocks that contain actual license statements.

This change was driven by the fact that today, most people acquire and
track Emulab and ProtoGENI sources via git.

Before the Emulab source code was kept in git, the Flux Research Group
at the University of Utah would roll distributions by making tar
files.  As part of that process, the Flux Group would replace the
license symbols in the source files with actual license statements.

When the Flux Group moved to git, people outside of the group started
to see the source files with the "unexpanded" symbols.  This meant
that people acquired source files without actual license statements in
them.  All the relevant files had Utah *copyright* statements in them,
but without the expanded *license* statements, the licensing status of
the source files was unclear.

This commit is intended to clear up that confusion.

Most Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the Affero GNU General Public License, version 3
(AGPLv3).

Most Utah-copyrighted files related to ProtoGENI are distributed under
the terms of the GENI Public License, which is a BSD-like open-source
license.

Some Utah-copyrighted files in the Emulab source tree are distributed
under the terms of the GNU Lesser General Public License, version 2.1
(LGPL).

backtick cat, open the file and read it like a real program would.

The current version of graphviz "dot" appears to put out positions as
floating point numbers rather than integers.  Change to accomodate.

Show id's on pc600 wifi cluster nodes.
Fix an areamap bug which offset areas on maps after the first, due to the bug that
required moving image cropping out of Perl ImageMagick and into shell ImageMagick cmds.

indexed by exptidx. I also got the last of the pid and pid,gid tables.

that filters on 'usrp' for GNU nodes.

* add an "active" flag to the template record, which will be used by
  the user to indicate what templates he wants listed (rather then the
  roots). Basically, the current working templates, rather then a big
  graph.

But I never actually finished that cause it sorta morphed into:

* Added a vis_graphs table to cache the last generated visualization
  rendering in the database so that we do not have to wait so long for:

* Add new buttons to showexp and template_show pages, to display in the
  same page either the settings (current view), the NS file, or the
  visualization (along with zoom in/out buttons).

And now I can go back to that "active" thing I mentioned up above ...

forthcoming ...

I fixed a couple of minor problems, but mostly this worked fine. Note that
I have tested this with the installed perl, *NOT* perl 5.8. I am just
making sure this stuff gets committed before too much more bitrot sets in.

Also filter out ROBOTS "buildings" when not under robotmap.

in the upper right hand side.

Ideally, we should put in full bars on both the X and Y axis, but that
was way too hard. Maybe Russ can work on that if we think its needed.

all the time. Turning on exclusions just extends the shading around
the object.  Also pay attention to new DB flag "no_exclusion" which
prevents the zone from ever being drawn, and is used to reduce visual
clutter by turning of the zone for some obstacles. Also remove the
blue border around the zones, again to reduce visual clutter.

but not put any actual robots on; that happens later when the tracker
applet runs and connects to the web server pipe.

file that doesn't exist in the tree.

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.

* 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.

Russ, I have no idea why this is here or how to get rid of it.

	my $out_width  = 792;
	my $out_height = 492;

Is there some way to get rid of these hardwired constants please?

* New database table to store obstacles, in the usual coord system;
  x1,y1, is the upper left corner.

* New web page to dump the entire obstacle list

	https://www.emulab.net/obstacle_list.php3

* New web page to dump a single obstacle, referenced by the above list
  page, and by the floormap generator.

* Hack up the floormap code to add obstacles to the areamap, so that
  when you mouse over them, you get a ballon showing the description,
  and a link to the above mentioned page.

nodes, and then if allocated and person has permission, the vname and
pid/eid.

Note that tip tool ballons have no formatting capabilities at all;
just a simple text string.

If we want fancier, I found some javascript code that will popup real
windows, and then kill them like a tool tip after a short pause or
when the user mouses out. The downside of the real window is that with
some window managers, you still get a status bar along the top, and so
it looks icky. The upside is that we can put real information and
formatting directives in the popup.

not have it do any zoom/pan stuff since that appears to screw up the
image when you click near the bottom of the image. No idea why, I just
avoid the code when new -z option is given. Also write the bounds of the
image to the state file. Might need this later.

script to avoid vis-ing parents of subnodes (ie. to avoid vis-ing
the PC hosting an IXP.) However, this was preventing us from vis-ing
fixed nodes at all.

option was given (as is when called from experiment page). This
restricts the nodes to just those in the experiment.

This interacts with ghosting mode (where other nodes on other floors
are shown). In the above case, should ghosting show all nodes on other
floors, or just nodes in the experiment on other floors? For now, it
does the latter, but it might useful to have a mode for the other
case?

This breaks the simple assertion throughout that the output image height is constant.

on the map.  Use a checkbox for control.  Turned at first by default.

Add scale 0 to use the thumbnail (40% reduced) images.  Scale 1 is still the default.

Declutter www by moving the static images into a www/floormap subdirectory.

work! The problem is that temp files will be owned by the user, not
the web interface, and so call out to backend to remove the tempfiles
with a new cleanup option.

generally improve the clarity and appearance of the maps.  The scale factor
buttons numbered 1-5 actually correspond to scale factors of 1, 1.5, 2, 2.5,
and 3.

Notice that the floorimages table in the database now has an integer "scale"
column to distinguish the cached zoomed-in images with a suffix "-[1-5].jpg" .

I use jpeg files instead of the png files that were used before.  They look as
good or better, and are a third the size.  Panning around at a given zoom
factor just involves cropping out a different rectangle of the scaled-up
images.

The 0311X064_[1-4]fl.pdf floor map files we got from Michael Kay started
out life in Adobe Illustrator.  Although GhostScript/gv crash while
trying to draw the pdf files, extracting them into PostScript files in
Acrobat on Coke allows GhostScript to render them flawlessly.

I started out using gs to render jpeg files in the shell, and then
found that ImageMagick uses the same GhostScript renderer, and nicely
handles cropping, drawing and annotations, and format conversion as well.

The PostScript rendering gets slow at higher zoom factors.  So I cache the
zoomed floor images, scaled up by rendering the PostScript files at a finer
dot-pitch (density) in GhostScript, and then cropping out the right rectangle
to register them properly.

For readability, and to avoid having the thin lines and bitmap fonts used in
some parts of the PostScript map from falling between the pixel cracks, I
actually render at twice the pixel density and filter down to the final image
with a gaussian -sharpen option to keep it from looking blurry.

ImageMagick is callable from both the shell and as the Image::Magick package
in Perl.  I converted the Perl logic in floormap.in to use Image::Magick
instead of the GD graphics library, resulting in anti-aliased (smoothed)
drawing of the wireless node dots and labels on floor maps for a better
appearance.  Then I added optional scaling and centering arguments which
select the proper cached zoomed-in image, and drive the logic for cropping and
drawing.

I modified the floormap.php3 file to wrap an input form around a set of zoom
control buttons and the floormap image.  The zoom buttons set the scale
argument to the Perl floormap script called on the server.  The floor map
image itself is wrapped in a graphical submit button, so clicking on it
returns the mouse coordinates within the image, which are then sent to the
centering argument of the Perl script.
