Change approveproject.php3 stuff so that approving ron includes pcwa.

subdirs and GNUmakefiles

cruft needed to compile ntfs support into imagezip, including the i18n
unicode library
routines from FBSD 5.0.  Most of the magic is in the makefiles, but there
is a patch for the ntfsprogs package we're using to get NTFS support.
(patch contributed by Russ).

Note that the ntfsprogs tarball is located in emulab webspace (like TG).

Don't worry!  You still have to pass --enable-windows to configure in order to
pull any of this in, although it should compile nicely from here on out.

Russ will commit his imagezip changes (hiber, and page file skipping) soon.

without first checking with the power that be.

with the testbed.

First, don't select a plink for an emulated link that would cause us
to go over bandwidth.

Second, make FIX_PLINK_ENDPOINTS the default, and add a #define that
makes it the default (instead of having to specify it on each plink
line.)

tbswap: re-enabled retry (Undid leigh's last change)

assign_wrapper.in:
   was left-joining reserved to nodes to get reserved list;
   This didn't get delays.

   now am doing separate query on reserved, and putting those
   into the %fixed and %alreadyAllocated hashes.

backend, but given that you have to mighty quick on the click, I never
bothered to put in the link. But I hear Mike is the quickest clicker
in the group.

anything conclusive, other than fork confuses mysqld, and our attempt
to unconfuse it by closing/opening the DB connection in the child,
confuses it even more! The parent connection is shutdown and then
restarted as well. In node_reboot, this could happen 10 times in rapid
succession as we fork as child for each node, and that appears to
strain the server even more (with 20 rapid connects).

So, I added a select(0.3) in TBdbfork() (in the child) to see if that
slows things down enough. In my tests, the length of time between the
parent and child operations makes a real difference. With a delay in
the child, the parent connection is not closed/restarted.

The astute reader will realize that I have no actual clue; just
grasping at, uh, threads.

case that they should use the subgroup, and since they also tend to be
in the clueless portion of our users, give them some help. Jay asked
for this months ago, and I always try to respond in a timely manner
when the boss asks for something!

simply compiled into tmcd itself.  We will probably extract them from the
DB a little down the road, possibly setting different values for different
projects, experimenters, etc.

state. Before, this caused "Running os Foo but in the wrong opmode!"
messages. Now, if I get to BOOTING and the state I'm coming from was ISUP,
and there's a next_op_mode waiting for me, force the mode transition

for delay nodes. Too many hacks to share an image!

Also a minor fix to emulated delayed lans; improper top file line.

node_reboot reports node activity into the "last_ext_act" column of
node_activity. (Ie activity that is external to the node.)

This means that swapin, swapout, reload, etc etc, anything that reboots
the node from boss/ops, will count as activity.

idle view) to 6 hours. (This will change again when the new slothd stuff
gets committed.)

leave your nodes idle. Also expanded section on "its important to swap out
on weekends" to include nighttime as well (in US timezones). This now is
pretty clear about the fact that people should typically be swapping out
if they're done for the day and aren't coming back until tomorrow morning.
Instead of the 24 hours that it used to talk about, it says "a few" or
"several" hours instead. (Not that anyone reads it, but at least it's
something we can point them to if they complain.)

encourage people to read them before they run into problems.

Also added a direct link to the advanced example, linked to in the first
para of the adv. tutorial.

Also removed "new" from the Emulab Internals page.

Ensure people don't miss step -1.

jail. This was attempting to get this from the tunnels table and
the interfaces table, but that was plain irritating. Just get it
from virt_nodes. Hey, its a virtual node, so use a virt table!

Here it is; reswap.

nfree
   - modified to put node in FREE_DIRTY when it is freed

assign_wrapper
   - '-u' update switch added.

os_setup
   - doesn't reboot node which is already in RES_READY

tbswap
   - calls all this stuff appropriately

(only 1 lan/link connection). An interim solution until we solve the
routing problem for "virtual" router nodes completely. Also added a
new global "enforce_user_restrictions" that you can set in your .ns
file to turn of this check, and some others.

"Version 1.02";
Fixed selection box drawing (was leaving 1 pixel of white on
bottomright side.)

Added ability to put '.' in all special-character-allowed places
(e.g., OSID, for Tim.)

Changed LAN Link behavior; now bw/delay/loss settings default to <auto>,
which means "inherit from LAN".
lan-node params are only spit out if any of those differ from the LAN.

setting port speed and duplex. Well, they probably do, in some MIB,
but not in the one we use on CatOS, and these features aren't actually
very important right now.

Also, make snmpit itself handle unsupported port operations.

to a specific one, for the purposes of mapping things like FBSD-STD to
FBSD47-STD (the current OSID to use). This is technically more correct
than what os_setup used to do, which was map FBSD-STD to whatever
FreeBSD OSID was currently on the disk. Now it maps to a specific one,
and if that is not loaded, it sets up a reload.
