of affairs.

This is apparently a no-no and was happening at DETER.

It isn't needed on clients and it requires the linuxthreads package
which is not otherwise needed.

I took it off when debugging popen streams on Windows; it shouldn't have been checked in.

to be reused if the DB is dropped and recreated, since when that
happens, auto_increment history is lost and it will go back to using
the latest highest index in the table. Usually not a problem, but
since we cross index three other tables using the experiment index,
this causes quite a bit of grief.

So, my solution is to do my own auto_increment using the
experiment_stats table (locked of course), which we never delete
entries from without deleting all entries from the other cross
referenced tables.

    DBQueryFatal("select MAX(exptidx) from experiment_stats");

I also added a sanity check to make sure the new index is not
currently in use in any of the tables. I also cleaned up the
error path when something goes wrong.

Add a cross-reference from the Windows installation section to the release notes section on setting up SSH or PuTTY/plink.

NFS, convert to using a proxy that runs on ops, which does the copying
locally.

Wrote new abstract and outline for WORLDS paper based on today's paper
meeting.

webfeedback to talk to the newer version of canaryd.  Add feedback
"estimate" stuff so that if we have no data (because of an overloaded
node) to work with, we can make some sort of "reasonable" guesstimate
on every iteration.

than jamming more stuff into the old one.  Most of the code came from
the previous version of canaryd, the cpu broker (process accounting),
and the janosvm (network interface accounting).  Its missing some
features of the old one, but those can be incorporated without too
much trouble.

Changes:

  Designed to permanently run on the pnodes:  it waits for START events
    before it begins recording.  However, I haven't done the work
    necessary to have it always startup on the pnodes.

  No more exec'ing: process stuff is taken from "/proc", and network
    interface stats are pulled from getifaddrs(3).

  Fixed some minor bugs: A typo caused the real-time priority to not
    be set, use setitimer instead of sleep to get more accurate
    spacing between samples.

return instead.

at the same time you clear the load address. admin people only.

instead of just their names.  Enhance experiment.statewait() to accept
multiple states to wait for, or, to wait for any state change.  Add
experiment.thumbnail() method so the topology can be displayed in
NetBuild.

event system from crashing when multiple EventClients are created.

Fix rather serious bug with how ranges interact with failed swapmod.
Actually, the bug is mostly in how a failed swapmod (or swapout)
results in missing testbed_stats records. I'm working on fixes for
that.

experiment is swapped or 2) the experiment is completely terminated.
In these case, lets put explicit swapout/destroy events into
testbed_stats so that the record is not confused by experiments that
appear to start when they are still running. This really throws off
the summary stats web page!

Ram into intro for the moment.

This is just a temp thing not to to miss some possibly useful text.

goes whacky.

Address some feedback comments, add more TOC, and add an extended example exploring the 2440 experiment graph and using the root glob expression option to experiment reading.

I will have to fix the bug in PyOpenGL argument passing to get
picking working right.

Meanwhile, I put in a simple work-around hack: when you pick a graph
edge in the spanning tree displayed by HyperViewer, the node it leads
to is picked instead.  (The edge has a negative integer ID, while the
node it leads to is positive.)

This also gives the ability to "zip" along edges of the graph, which
I kind of like.  It's not a very good substitute for picking nodes,
but might be worth keeping even after node picking works.  We can
also define our own semantics for picking edges in the graph...

an OS, the code to check for the presence of non-BSD nodes would fail.
Fixed the check so that we consider a PC to be a non-BSD node if we have
no information about what default OS is gonna be loaded on to a PC after
mapping. Lunquan Li of WormE project triggered this problem.

BUGFIX

IPOD packet, now you can.  (Note that having ipod installed setuid
is already a moderate risk, so i don't think this makes it too
much worse)
