      * Replace the argument processing code in all pages. Currently we rely on · 48acc8e3

        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.

      Change how the archive stuff is presented in the template instance and · 808f43ec
      Leigh B. Stoller authored
      run display pages.
      
      * Add new code to archive_control and libarchive to create tags (in
        optional subdirs) of the tags directory. These tags are simply tags
        on the current trunk at the time.
      
      * Change to template instantiate and start/top run code to create a
        "runs" directory. Within the runs directory are subdirs named for
        each runid, and within this directory are start and stop run tags.
        Eventually add some other tags when doing swapmods, but do not have
        that figured out yet.
      
      * Change the viewcvs code to add an "embedded" view of an archive.
        This is just an alternate view that has no header/footer goo, but
        only the actual svn contents. The main reason for this change is
        that the header and footers take up a huge amount of space and
        contribute nothing. Smaller means its easier to add to the instance
        and run show pages.
      
      * Add the above mentioned embedded archive view to the instance and
        run show pages. On the instance page you see the directory of all
        runids, and on the show run page you see the subdir for that run.
