I've fixed all existing group directories.

just like /proj/$pid.

in /proj/$pid/exp/$eid, since this would seem to violate group
privacy (/proj exported to all experiments). Minor changes to owner
and mode to allow for non group members to swap/terminate and not get
copy error (of logs).

it was causing copy errors when non-group members try to swap an
experiment. Make it 664 instead.

In addition to the usual checks, project_root and group_root (in the
project) get the same permission as if they were in the subgroups with
group_root permission. This means they can swap/terminate/reboot etc
in subgroups even though they are not members of the subgroups.
There is still some copy problems with files, but leaving that till
later to deal with.

wrt subgroups. Also noted that group created is no longer in the group
by default.

project pages. Also fix the group one to be more consistent with the
others.

-s is now required to set bits, and there is a -p option so that you
can give physical node names.

Allow use of node classes, as well as types, in the template file.

New tbswap mode 'update'. (a.k.a. 'reswap')
Re-assigns experiment, fixing already assigned nodes in place;
tries not to reboot nodes. Doesn't clear port counters,
restart event system, etc.

A few more things remain to be considered for 'general' use
adding new nodes to experiments and modifying topologies,
but for replacing failed nodes in experiments
or removing virt_nodes from experiments, should work fine.

how long they've been idle and what the time of last activity was on their
nodes. And now do proper wordwrapping on the message instead of static
apriori newline placement.

Also add the ability to do some formatting on the idle time to those
functions, and use it to make the swap request message a little better.
("H hours, M minutes" instead of "X.Y hours").

directory, so that mysql can write its logs.

only pid, to pid/gid like most other things in the testbed. Also add a
"global" slot to denote images that are globally available to all
projects (system images). The older "shared" attribute is now used to
denote images that are shared within a project (available to all
subgroups in the project). The migration path for existing DBs is
given in the migrate file. Be sure to run those commands on an
existing testbed or things will break!

www/newimageid, www/newimageid_ez: A bunch of changes for
shared/global attributes. Added a group menu to the form so users can
create images in subgroups. Beefed up the Java code that constructs
the path name to use the gid, shared, and global attributes of the
form to give the user the best possible path that we can. Improved the
pathname checking code so that we do not allow just any old path in
case the user elects to disregard the path we carefully constructed
for them. Also check the proj/group membership, and setup defaults for
users that have permission in just one pid/gid to create images.

libdb.in: Changed permission check in TBImageIDAccessCheck() to
reflect shared/global attribute changes.

os_load: Get rid of test that checked path of the image. The path
checking is done in the web interface anyway, so why duplicate in 4
places. Other minor changes reflecting shared->global name change.
Also note that images can come from the group directory now.

create_image: Get rid of test that checked path of the image. The path
checking is done in the web interface anyway, so why duplicate in 4
places. Also note that images can come from the group directory now.

www/dbdefs: Changed permission check in TBImageIDAccessCheck() to
reflect shared/global attribute changes.

www/showimageid_list, www/showstuff: Minor global/shared attribute
changes.

www/menu: Change osids/imageids pointer to point to the image list,
not the osid list. This is more reasonable for mere users who have
access to the EZ form, and thus never really need to concern
themselves with osids.

www/editimageid: Add proper pathname checking. There were no checks at
all before!

 - Added a bunch of functions to get time of last activity, hours idle,
   and staleness for nodes and experiments.
 - Fixed the showexp_list page to use the new idle measures, including
   idle view. Idle view now runs in about 1.3 seconds instead of 13.
 - Changed all the "show" functions for nodes and expts to show idleness.

More changes will be coming, but I wanted to commit this before I install
it for real.

when a new LAN is created, we make a new plink. Since assign is only
halfway OO, there is no constuctor for a plink to set the fixends
flag to something sensible.

Turned back on FIX_PLINK_ENDPOINTS, and 'touch' score.cc so that it
gets rebuilt.

   - Performing an approval action (postpone/approve/deny/nuke) on a
     user in a subgroup results in an implicit version of that same
     approval action on the user in the
     default group (for approve, $trust='user'.)

   - Tidied up a table in approveuser_form.php3,
     but form is otherwise unchanged.

the newimageid_explain front page, since I had actually moved most of
that text into the tutorial a couple of months ago. I moved the rest
of the text over, and changed the links to point to the short form.
Added a link at the top of the short form pointing to the tutorial
section, and for admin types, a link to the long form.

Account to make it more clear.

Bad idea. Use an auto_incrementing idx field instead.

Fixed bug where after running out of retry attempts,
swapout was only doing the 'retry' version of cleanup,
when it should have been doing a full cleanup.

and a query returns a null where it ain't supposed to!

by assign_wrapper to help control emulated links. When set for an
emulated link, assign uses the BW spec for mapping the links (onto
phys links) but does not insert a linkdelay to traffic shape it
(unless the link is shaped in some other manner, like a delay or plr,
in which case a linkdelay is inserted, but with no bw cap). This might
be temporary syntax, expecially if we cannot make emulated links work
right!
