fully integrated Trac. I put a new installation in /usr/local/www/data/trac
and I added all the hooks for adding users and doing the cross machine
login. Only STUDLY() users will actually see the new option in the collab
dropdown menu.

I have not done anything to make the trac installation look like Emulab.

menus.

it can be actively clicked and toggled between the short status view and
the long freenode view. There was no way to do this when it was an iframe,
and the upside of not using an iframe is that iframes often mess up rendering
and cause many cross-browser problems.

Since its not an iframe, I have to hook into the Sajax stuff even on
pages that already use Sajax, and I want to go to a different URL then
the current page (want to use currentusage.php3). So I tweaked the Sajax
stuff a bit, and roll out some inline sajax code in PAGEFOOTER().

Also, at Rob's request I added a cookie to remember the state of the
user's choice so that subsequent page loads get the same view. This
is done with an inline cookie in the javascript (document.cookies).

makes formatting super wide tables really hard to do in a cross
browser manner (that I can tolerate). Also improve visual separation
of the top banner from the content title area.

different.

Temporary switch to style-new.css for a few days since many browsers do
not reload the style files for some reason.

menus that used to be on the left side, are now drop down menus along
the top. The banner across the top will also be smaller and more space
efficient.

The primary motivation for these changes is to leave more room for
actual content in the main window.

Tested with Firefox (1.5 and 2.0), Safari (2.0 and 3.0) and on
Internet Explorer Version 7. IE6 has some visual issues that might
make it a little annoying, but should be viewed as incentive to
upgrade to IE7 since it has been out a long time.

then putting in javascript below each sorted table, instead call
AddSortedTable($table_id), which will cause a block of javascript to
get spit out in the page footer.

* Reorg the CVS repo so that records and setup are toplevel modules in
  the repo, instead of directories in a single module named by the
  guid (which is redundant and annoying).

* Some changes to the spewlog stuff. It used to handle only
  experiments, but I really wanted it to handle template create and
  modify. Took a bunch of small changes to a lot of places to make
  this work correctly, but it was worth it.

  There are some changes I made that I can retrofit to the other spew
  pages to make it look a little nicer at the top of the page, to use
  less space.

Turn on $javascript_debug at the top of menu.php3, and then use warn()
statements in the code to have those debug statements turn up at the
bottom of the page. This is the most cross-browser implementation I could
find (which means it works on Safari, IE, and Firefox).

it too, but its not like people use the page that much, so not gonna
bother.

Basically, this lets you search the Emulab docs from the same little
toolbar box that lets you search google, etc.

Works with Firefox 2.0, and should work with IE 7

only one 'flower' so that the whole thing can look clearer. Include
a 32x32 version in the file for browsers using larger status lines.

when they have changed. So, change the URL for our stylesheet in
order to force browsers to load a new version. (I installed this
manually on boss.)

This should be removed before making a release!

enumerates the different experimental environments we support. Most
of the new text only gets displayed at Utah, since no one else has
wireless nodes, etc. Other sites get some short generic text.

New banner, plus other visual tweaks. The new banner is turned on via
the new @FANCYBANNER@ autoconf variable. This is turned on for
TBMAINSITE, but defaults to off for other sites. This is so that
existing sites which already have their own versions of the old banner
don't have to update them right away.

Made the usage iframe a little less prominent, by darkening it, and
making it ever so slightly transparent on browsers that support it.

Some minor visual tweaks to the background and content area.

Added specific IDs for the main menu subgroups so that if we want, we
can style them differently.

Man, IE is a pain in the ass.

  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.

converting to locally unique ids and later globally unique ids.

various template operations to get lost. Also fixed the code in
mungelog.js that was supposed to handle bailing out if there was no
response from the server in a reasonable amount of time; if that code
had been working, no one would have even noticed all the other problems!

Also some cleanup in parts of mungelog.js and showlogfile_sup.php3;
slowly migrating parts of this to emulab_sup.js since we use some of
the same code in other places.
