Added distributed start times during an INIT to spread out the scheduled test times over half the desired period.

Added error codes for determining "down paths" using a bw value of -1 or -3 to indicate a timeout or "unknown" (such as bad host name, no socket, etc..), respectively.

Some other miscellaneous changes.

Quick fix for a race condition in the auto-framework. This makes the race condition happen less, but it still happens. The real solution is to have the stub daemon-ize itself just before it is ready to accept connections.

Various bug fixes. Especially with the system for determining whether a connection is sending as fast as it can. Now it correctly determines when it is in slow start, and when the receivers buffer is empty so that these do not cause erroneously small bandwidth/max_delay figures.

Basic skeleton. Not functional yet. Getting this working and then adding some modules is what comes next.

between multiple link characteristics which are defined in the data file.
As a result, any type of link characteristic for the mote, wifi, or SDR
testbeds can be shown as long as it's in the file.  Also partial support
for metacharacteristics (things like the min/max/stddev of a single link's
primary characteristic).

Basically, a nice refactor into what I hope is complete flexibility
for display of any kind of link characteristic on any of our wireless
testbeds.

Fix HTML "character entity" references like &amp missing the trailing semicolon.  This is actually a bug in the Cocoon online doc generator, affecting anchors for C++ functions with a reference ampersand in the type signature.

Apparently that port is long (long) dead, and somewhere along the line
the stuff that sits below it changed, which caused our stuff to break.

The modern and maintained version of the same API is now
/usr/ports/databases/p5-DBD-mysql (/usr/ports/databases/p5-DBD-mysql50
when using mysql 5.0).

Fixed perl warning about Use of uninitialized value in numeric gt.

Load up the madwifi driver after the wired ones and after dhcp is finished
to avoid the latter succeeding on the wifi interface (this behavior has been
seen several times).

Fix a couple of typos.

support in place.

Many changes to tblog code.  Database update needed:

1) Added summary of failed nodes is os_setup.  The cause of the error is now
classified as "user" if it is only user images that failed and the user
image failed on every pc of a particular type.  Otherwise I leave the cause
as "unknown" since it is really hard to tell what the real cause is.

2) Raised the confidence threshold for most errors so that they will appear
on the top.

3) Added a special error when an experiment is canceled.  The cause is
"canceled" and testbed-ops won't see these errors.

4) Fixed a bug in assign_wrapper where it will incorrectly report "This
experiment cannot be instantiated on this testbed..." when really the user
canceled the swapin.

5) Fixed a bug where os_setup errors where being incorrectly reported as
assign errors.  This happens when os_setup fails for some reason and
tbswap tries again, but the second time around there are not enough nodes.
So the last error is coming from assign even though the true cause of the
error is due to failed nodes.  The fix for this involved added a new column
to the log table, "attempt", which will be 1 for the first attempt and then
incremented for each new attempt.  tblog_find_error will then simply ignore
any errors with "attempt > 1".

6) Also fixed a potential problem when there is an error during the cleanup
phase by adding another column "cleanup".  tblog_find_error will
also ignore any errors with the cleanup bit set.

browser confusion that results when the same cookie name is used on
multiple elabinelab experiments.

revision 4.70.

mysqld does not properly detach, and the funky shell script startup
that is uses causes mysqld to not detach properly, and when the parent
exits, the process group gets a SIGHUP. Well, in mysql 5.0 a HUP
causes the mysqld to reload its grant tables, even though it was
started with --skip-grant-tables, which causes everything on boss to
completely break.

So, on FreeBSD6, start mysqld with "daemon" utility program, which
does the proper detach.

Actually, most of the changes here were just to generalize the "virtual
interface" state in the DB.  Other than the client-side scripts, there
is very little specific here specific to tagged VLANs.

In fact, you cannot specify "vlan" as a type yet as we haven't done the
snmpit support for setting up the switches.

For more info see bas:~mike/flux/doc/testbed-virtinterfaces.txt, which I
will integrate into the knowledge base and the Emulab doc at some point.

to do everything!

Convert the atheros/wifi setup to work with the madwifi-ng driver.

It mostly incorporates (part of) what is currently spread all over
libdb.pm, and so far I have converted just batchexp to use it.
I will be converting scripts over time ... but you might want to look
at this module now and start using it.
