      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      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).

      do this the PAGEHEADER call needed to be moved to after

      warning will be printed if either CheckLoginOrDie or
      Required/OptionalPageArguments detects that PAGEHEADER was already
      called.
      
      Also change the redirect in kb-show to be a permanent redirect (301)
      rather than a temporary one (302) which is the default unless a status
      code is given.

      * Replace the argument processing code in all pages. Currently we rely on · 48acc8e3
      Leigh Stoller authored
        register_globals=1 to turn POST/GET/COOKIES arguments in local variables.
        This is known to be a terrible security risk, and we keep saying we are
        going to fix it, and now I am. In order to accomplish this on a
        transitional basis (since I don't want the entire web interface to stop
        working while I debug it), and because the code just needs the cleanup, I
        am doing it like this: Each page will sport new declarations at the top:
      
      	RequiredPageArguments("experiment", PAGEARG_EXPERIMENT,
                                    "template",   PAGEARG_TEMPLATE,
                                    "instance",   PAGEARG_INSTANCE,
                                    "metadata",   PAGEARG_METADATA,
                                    "osinfo",     PAGEARG_OSINFO,
                                    "image",      PAGEARG_IMAGE,
                                    "project",    PAGEARG_PROJECT,
                                    "group",      PAGEARG_GROUP,
                                    "user",       PAGEARG_USER,
      			      "node",       PAGEARG_NODE,
      			      "yesno",      PAGEARG_BOOLEAN,
      			      "message",    PAGEARG_STRING,
      			      "age",        PAGEARG_INTEGER,
                                    "cost",       PAGEARG_NUMERIC,
                                    "formfields", PAGEARG_ARRAY,
                                    "unknown",    PAGEARG_ANYTHING);
      
      	OptionalPageArguments("canceled", PAGEARG_BOOLEAN);
      
        The first token in each pair is the name of the global variable to
        set, and the second token is the type. So, for "experiment" we look at
        the URL for a pid/eid or exptidx, etc, sanity check them (safe for a
        DB query), and then try to find that experiment in the DB. If it maps
        to an experiment, set global variable $experiment to the object. Since
        its a required argument, produce an error if not supplied. Similar
        treatment for optional arguments, with the obvious difference.
      
        The goal is to have ALL argument processing in one place, consistent,
        and correct. I've found numerous places where we leak unchecked
        arguments into queries. It also cuts out a lot of duplicated code.
      
      * To make the above easier to deal with, I've been replacing lots of
        hardcoded URLS in the code of the form:
      
      	foo.php3?pid=$pid&eid=$eid ...
      
        with
      
              CreateURL("foo", $experiment)
      
        which creates and returns the neccessary url string, by looking at
        the type of its arguments (experiment, template, instance, etc.)
      
        Eventually plan to replace them all so that URL handling throughout
        the code is all defined in one place (all the new URL code is in
        url_defs.php).
      
      * I have cranked up error reporting to tell me anytime a variable is
        used before it is initialized, plus a bunch of other stuff that PHP
        deems improper. Think of it like -Wall ... and boy we get a lot of
        warnings.  A very large percentage of the diffs are to fix all these
        warnings.
      
        The warnings are currently going to /usr/testbed/log/php-errors.log,
        and I'll be adding a script to capture them each night and mail them
        to tbops. This file also gets errors (this will be a change for
        developers; rather then seeing errors and warnings dumped in the
        middle of web pages, they will go to this file instead).
      
      * Major refactoring of the code. More objects (nodes, images, osids).
        Moving tons of queries into the objects in the hopes of someday
        getting to a point where we can split the web interface onto a
        different server.  Lots of general cleanup.

      Overview: Add Event Groups: · ed964507
      Leigh Stoller authored
      	set g1 [new EventGroup $ns]
      	$g1 add  $link0 $link1
      	$ns at 60.0 "$g1 down"
      
      See the new advanced tutorial section on event groups for a better
      example.
      
      Changed tbreport to dump the event groups table when in summary mode.
      At the same time, I changed tbreport to use the recently added
      virt_lans:vnode and ip slots, decprecating virt_nodes:ips in one more
      place. I also changed the web interface to always dump the event and
      event group summaries.
      
      The parser gets a new file (event.tcl), and the "at" method deals with
      event group events by expanding them inline into individual events
      sent to each member. For some agents, this is unavoidable; traffic
      generators get the initial params in the event, so it is not possible
      to send a single event to all members of the group. Same goes for
      program objects, although program objects do default to the initial
      command now, at least on new images.
      
      Changed the event scheduler to load the event groups table. The
      current operation is that the scheduler expands events sent to a
      group, into a set of distinct events sent to each member of the
      group. At some point we proably want to optimize this by telling the
      agents (running on the nodes) what groups they are members of.
      
      Other News: Added a "mustdelay" slot to the virt_lans table so the
      parser can tell assign_wrapper that a link needs to be delayed, say if
      there are events or if the link is red/gred. Previously,
      assign_wrapper tried to figure this out by looking at the event list,
      etc. I have removed that code; see database-migrate for instructions
      on how to initialize this slot in existing experiments. assign_wrapper
      is free to ignore or insert delays anyway, but having the parser do
      this makes more sense.
      
      I also made some "rename" changes to the parser wrt queues and lans
      and links. Not really necessary, but I got sidetracked (for several
      hours!) trying to understand that rename stuff a little better, and
      now I do.

      Fixed up 'detail' options for viz, and changed
      to using a table to position viz image..
      Should be a slight improvement.

      Added thumbnail (2x as large as the one which shows up in the list) to showexp page.
      Added heading to vis(shownsfile), showexp and showproj pages, to more readily identify what you're looking at.
      Added links from thumbnails to vis(shownsfile) page.
      Added submenu hackiness to menu.php3 to allow embedding of things into left panel below submenu.
      Removed "red letter" legend and PC  summary from bottom of thumbnail view.

        - Node type
        - Node IP listing
        - Link characteristics
           - always shows bw
           - shows latency if > 0
           - shows loss if > 0%
      
      Added links in shownsfile.php3 for specifying zoom and more/less detail.
