GitLab

its own subsection, and admin funcs in another one. (These both only show
up when you're red-dotted.)

Reusable SUBMENUSECTION($title) calls added, so you can do this in any of
these submenus.

Added 6px of spacing to right of submenu.
Should help with existing submenu crowding, as well
as Mac's forthcoming changes.

emulab pub/priv key pair I installed yesterday.

Also committed some stuff for running tmcd on ops. Not in production
yet. Someday.

like we set hostnames of local nodes (v0.wa-jail-link.testbed.emulab.net).
Also build a proper /etc/hosts file just like local nodes inside the
jail. Minor change to dohostnames(); do not munge /etc/hosts in place!
Generate a new copy and then atomically move into place. Phew, this
was a close one! Mike has me really worried about race conditions now
that I screwed the pooch in the frisbee client.

field.  This is NOT just an aesthetic change, it fixes a once-in-a-blue-
moon race (that happened just yesterday) where the disk write thread
cleared ready and then inprogress as two seperate assignments and got
context switched after the first.  The result was that the net thread
saw a chunk that was inprogress even though all blocks had been received
and it issued a zero-block request.  This triggered an assert in the server.
Note that if we were prissy we would protect chunk buffer accesses with
a mutex, but that is overkill for this single piece of shared state that
can be protected via the "reasonable" atomicity of a write instruction.

who gets root on widearea nodes, inside and outside of jail. Kinda
brute force; might need to make this more flexible at some point,
perhaps with a node/user mapping table for widearearoot (root outside
the jail), and a widearea_trust slot to the group_membership table
(root inside a jail), but this will do for now since its handled
entirely inside of tmcd.

I was originally using local_root to determine root access inside the
jail, but we need to more finely control who gets root on widearea
nodes. Outside the jail, only tbadmin got jail, and thats definitely
too restrictive!

virtnodes in the nodes table so as not to pollute the map with a
zillion nodes that do not actually exist. But, once allocated go ahead
and generate a CNAME so that vwa44-1.emulab.net maps to something (the
"control" net interface).

get the client tracking code right this time!

on any node on any state, in any specific mode, or without any mode
restriction.

The imediate use of this is the FREENODE trigger. Now RELOADDONE adds
a FREENODE trigger on the ISUP state, if the node is in the reloading
expt. Then next time the node hits ISUP, it gets freed from the
reloading expt.

This fix solves the race where recently freed (and still rebooting)
nodes get grabbed by an expt and get rebooted in a way that may hoze
their FS's.

Also fixed a problem that was making it load the db twice on startup.

TBDB_NODEOPMODE_ANY = '*'

Fixed up 'detail' options for viz, and changed
to using a table to position viz image..
Should be a slight improvement.

Add features and desires to the PER_VNODE_TT restrictions. For
desires, we can tell the user which ones can't be satisfied, but for
features, we don't even try to figure out which one(s) keep us from
mapping. From the assign_todo file, this is:
9.   add features/desires to PER_VNODE_TT restrictions

Add a new -P switch, when PER_VNODE_TT is in use. This casues it to
prune out pclasses that no vnode can map to - this can lead to _huge_
time savings, particularly since we put things like wide-area nodes
into the ptop file. I've seen a 98% reduction in time when using both
-p and -P! But, it's not the default yet, because I need to do more
testing to make sure that this isn't hurting solution quality
significantly.  todo item:
8.   prune pclasses when using PER_VNODE_TT

Standardize the exit values from assign:
On success, returns 0
On failures that are not retryable (ie. this top can never be mapped
    to this ptop), returns 2
If SA fails to find a solution (ie., we might consider retrying),
    returns 1

Fix a bug that has annoyed me for a very, very long time - if the
input files don't exist, exit instead of hanging forever!

Make the weight at which a feature/desire is considered 'hard' (ie. it
generates a violation if unsatisifed or undesired) a variable, so that
we'll be able to change it from 1.0 if we want.

Put some more messages that should appear inline in the mail to stderr
instead of stdout.

suffered some bitrot, but its now in sync and running on wa44, which
is destined to be the source of the next image.

Add new crontab file install to run a stub crontab inside jails;
basically, runs the atq and the newsyslog stuff. Other stuff is
turned off including periodic.

Change paths for the vtun debug files to /var/emulab/logs.

accounts on ops. Might be a while before I get back to this.

/users filesystem.

For the benefit of our users,
added 'reboot nodes in experiment' checkbox,
on by default, with a stern warning.

Added "check sitevars" to build, so we can be sure
other sites have all of the requisite site variables
when they install.

Some of it is new; some of it is modified versions
of Rob's schemacheck stuff.

Reorder some options to put force swap (idle-swap) up near the other swap button, so I don't accidentally use the wrong one.

Yep, years from now someone will look at this commit and wonder.

Clear out nsfiles and experiments, since tbend does not do that.
Clear out all users except the person running the test.
DB size is now half of what it was; less churning!

Altered item headers so they don't look bad on modern browsers.
