of problem in PHP with the unsigned int value from the regex table
for default:int, which I need to look at, but in the meantime add
proper bounds checks for the numeric fields in the new project table.

instead of virt_nodes:vname. This is coz the vnode can have a '*'. This should
fix the repeated expt creation errors today in project DNA.

simhost_violation to the reserved table. Details in the migrate file.
Note that virt_simnode_attributes is part of the virtual state and is
being taken care of in libdb.

now have ways to make them non-interactive, and we can take care of
adding optional 'sub-packages' to mod_php4 ourselves; we don't have
to make the user do that.

sending an ISUP. ISUP is now sent as the first event from the nse scheduler.

error - it's too hard to destingish a string from 0 in php, and every
place we call this function, we've already made sure the group exists
anyway.

account, and direct user to Forgot Username/Password page.

Changed the Forgot page to allow user to *either* reset password, or
just find out their username if that is what they forgot.

usually handled via uid cookie we get back from the browser, but if
the user Clicks stop or maybe has cookies off, we don't that info.

In the top file, you can provide a 'node-hint', which is similar to a
'fix-node' in that it specifies a starting mapping for the virtual
node. Unlike a fixed node, however, assign is allowed to move hinted
nodes around all it wants.

Add a '-t' option to assign that allows you to give a starting
temperature, instead of going through the usual melting process.

Together, these may be helpful with the pre-pass we're planning on
incorporating into assign. During that pass, assign will be working
on a coarsened version of the virtual graph, so there may be some
places where decisions are made poorly due to the reduced information.
After one run has been done with the coarsened version, we can run
assign again with the full version of the graph, but with 'node-hints'
that start virtual nodes where the first run decided. This will allow
assign to fine-tune the results of the first mapping.

Of course, we don't want this second run to take too long, so we'll
want to start it with a low initial temperature (so that it basically
just does hill-climbing), and probably use a fractional '-H' argument
to prevent it from spending too long on large topologies.

zillions of DB fields that we have to set. My solution was to add a
meta table that describes what is a legal value for each table/slot
for which we take from user input. The table looks like this right
now, but is likely to adapt as we get more experience with this
approach (or it might get tossed if it turns out to be a pain in the
ass!).

	CREATE TABLE table_regex (
	  table_name varchar(64) NOT NULL default '',
	  column_name varchar(64) NOT NULL default '',
	  column_type enum('text','int','float') default NULL,
	  check_type enum('regex','function','redirect') default NULL,
	  check tinytext NOT NULL,
	  min int(11) NOT NULL default '0',
	  max int(11) NOT NULL default '0',
	  comment tinytext,
	  UNIQUE KEY table_name (table_name,column_name)
	) TYPE=MyISAM;

Entries in this table look like this:

	('virt_nodes','vname','text','regex','^[-\\w]+$',1,32,NULL);

Which says that the vname slot of the virt_nodes table (which we trust the
user to give us in some form) is a text field to be checked with the given
regex (perlre of course), and that the min/max length of the text field is
1 and 32 chars respectively.

Now, you wouldn't want to write the same regex over and over, and since we
use the same fields in many tables (like pid, eid, vname, etc) there is an
option to redirect to another entry (recursively). So, for "PID" I do this:

        ('eventlist','pid','text','redirect','projects:pid',0,0,NULL);

which redirects to:

	('projects','pid','text','regex','^[a-zA-Z][-\\w]+$',2,12,NULL);

And, for many fields you just want to describe generically what could go
into it. For that I have defined some default fields. For example, a user
description:

        ('experiment,'usr_name','text','redirect','default:tinytext',0,0,NULL);

which redirects to:

	('default','tinytext','text','regex','^[\\040-\\176]*$',0,256,NULL);

and this says that a tinytext (in our little corner of the database
universe) field can have printable characters (but not a newline), and
since its a tinytext field, its maxlen is 256 chars.

You also have integer fields, but these are little more irksome in the
details.

	('default','tinyint,'int,'regex','^[\\d]+$',-128,127,NULL);

and you would use this anyplace you do not care about the min/max values
being something specific in the tinyint range. The range for a float is of
course stated as an integer, and thats kinda bogus, but we do not have many
floats, and they generally do not take on specific values anyway.

A note about the min/max fields and redirecting. If the initial entry has
non-zero min/max fields, those are the min mac fields used. Otherwise they
come from the default. So for example, you can do this:

    ('experiments','mem_usage','int','redirect','default:tinyint',0,5,NULL);

So, you can redirect to the standard "tinyint" regular expression, but you
still get to define min/max for the specific field.

Isn't this is really neat and really obtuse too? Sure, you can say it.

Anyway, xmlconvert now sends all of its input through these checks (its
all wrapped up in library calls), and if a slot does not have an entry, it
throws an error so that we are forced to define entries for new slots as we
add them.

In the web page, I have changed all of the public pages (login, join
project, new project, and a couple of others) to also use these checks.
As with the perl code, its all wrapped up in a library. Lots more code
needs to be changed of course, but this is a start.

addslashes getting called, once in the web interface and again in the
perl backend.

'slot'. In the top file, you can how give' the virtual node's type as
type:count - sim:5, for example. If you give no count, it defaults to
one.

The idea here is to allow a pre-pass to assign to 'coarsen' the
virtual graph. This pre-pass could, for example, combine several
virtual or simulated nodes into one so that assign has a simpler
virtual graph to work with.

put special characters in them.

Added table_regex to the list of exported tables that needs to be
checked at install.

code to run as uid/gid nobody/nobody. I had to remove dolog(), which
was to support the oskit on the dnards, so no one will miss that!
I also removed the tar/rpm download support since we now do that via
the web interface. To support sfshostid, I had to chown/chgrp
/proj/.sfs to the nobody/nobody so that tmcd willbe able to create the
symlinks in that directory.

If plabmetrics succeeds and it has been more than two intervals since the
last mod, send a "back in business" message.

Also fixed up the makefile for compilation and installation (client).
