Log:
Commit functioning XML interface. At present, only isadmin people will
see this new page. That allows me to inflict pain on testbed
developers while we work out any kinks. These new pages implement an
XML interface to experiment creation.
Some new files:
beginexp_html.php3: A wrapper for the actual beginexp form. This page
includes the form, and then invokes the XMLRPC backend page.
beginexp_form.html: The original form code, split out from beginexp
and turned into a module that can be included into another file. It
is slightly reorganized to make it easier to include as a module. The
idea is that the plab_ez form will be recast in this model, reducing
some redundant complexity.
beginexp_xml.php3: The XML backend. The idea is that the html page
packages up the form arguments as an XMLRPC message, and invokes this
page with the XML goo encoded in the URL. It also passes along the
uid/cookie so that the authentication happens properly (https of
course). The page decodes the URL into PHP datatypes, and does much of
the same argument checking that beginexp used to do. Errors are stored
up in the same manner, but instead of spitting back html, it now spits
back a "structure", encoded in XML so that the _html page can put up a
new form. Basically, all output is sent back via an XML encoded
structure and displayed in a form that the invoking script deems
appropriate.
This gives us a pure XMLRPC interface, which we wrap with a form interface
so that it looks just like it did before.
The next step is to provide an alternate front end, but that will require
some certificate stuff that I have not worked out yet.
Oh, one more item. The syntax check stuff has been altered a bit.
Instead of invoking the beginexp page, which meant a zillion special
tests, I now invoke nscheck.php3 directly from the button. Took a few
extra lines of Javascript to do this, so watch out for problems there
too.

Log:
Distributed NSE changes. In other words, simulation resources are
now mapped to more than one PC if required. The simnode_capacity
column in the node_types table determines how many sim nodes can
be packed on one PC. The packing factor can also be controlled via
tb-set-colocate-factor to be smaller than simnode_capacity.
- No frontend code changes. To summarize:
$ns make-simulated {
...
}
is still the easy way to put a whole bunch of Tcl code to be
in simulation.
One unrelated fix in the frontend code is to fix the
xmlencode() function which prior to this would knock off
newlines from columns in the XML output. This affected
nseconfigs since it is one of the few columns with embedded
newlines. Also changed the event type and event object type
in traffic.tcl from TRAFGEN/MODIFY to NSE/NSEEVENT.
- More Tcl code in a new directory tbsetup/nseparse
-> Runs on ops similar to the main parser. This is invoked
from assign_wrapper in the end if there are simnodes
-> Partitions the Tcl code into multiple Tcl specifications
and updates the nseconfigs table via xmlconvert
-> Comes with a lot of caveats. Arbitrary Tcl code such as user
specified objects or procedures will not be re-generated. For
example, if a user wanted a procedure to be included in Tcl
code for all partitions, there is no way for code in nseparse
to do that. Besides that, it needs to be tested more thoroughly.
- xmlconvert has a new option -s. When invoked with this option,
the experiments table is not allowed to be modified. Also,
virtual tables are just updated (as opposed to deleting
all rows in the first invocation before inserting new rows)
- nse.patch has all the IP address related changes committed in
iversion 1.11 + 2 other changes. 1) MTU discovery support in
the ICMP agent 2) "$ns rlink" mechanism for sim node to real
node links
- nseinput.tcl includes several client side changes to add IP
routes in NSE and the kernel routing table for packets crossing
pnodes. Also made the parsing of tmcc command output more robust
to new changes. Other client side changes in libsetup.pm and other
scripts to run nse, are also in this commit
- Besides the expected changes in assign_wrapper for simulated nodes,
the interfaces and veth_interfaces tables are updated with
routing table identifiers (rtabid). The tmcd changes are already
committed. This field is used only by sim hosts on the client side.
Of course, they can be used by jails as well if desired.
