make-flight: create the vNUMA HVM test job
as a variant of regular Debian HVM jobs.
For now, the vNUMA topology is just hardcoded
here, and it is 4 vCPUs and 2 vNUMA nodes. How
to split resources is left to the test
implementation (right now, it is just evenly
split them between the 2 virtual nodes).
Note that we do not yet support save/restore
and migration for vNUMA enabled guests, so
this test will fail (and in fact, it's added
to the non-blocking list).
Since I think we should, at some point, support
both, things are ok to be that way.

This is done by introducing a new guest runvar, called
'vnodes', holding, if defined, the number of vNUMA nodes
the guest should have.
From that, and basing on the other characteristics of the
guest (namely, amount of RAM and number of vcpus), we build
a vNUMA topology that makes sense.
For now, we just evenly (well, as evenly as we can) split
resouces between vNUMA nodes. Also, still for now, we
always set things in such a way that all vNUMA nodes are
allocated on physical NUMA node 0. This way, we don't
have to introduce logic to make sure that the test runs
on an actual NUMA host.

If an osstest instance is running flights with
OSSTEST_BASELINES_ONLY=y (e.g. on a secondary site, like the Citrix
Cambridge instance) then it will also be running a regular osstest
flight to merge from the upstream osstest and does not want to also do

I expect this will be the normal configuration in all sites other than
the master colo production instance, so arrange for it via
branch-settings.osstest rather than some site local configuration file.

Debian: Wait for udev devices to settle in erase-other-disks
Otherwise we, apparently, have a race between the "test -b" + dd
against the sda1 device node being removed and end up creating a file
called /dev/sda1 containing 32K of zeroes, which will later render
mke2fs very confused.
For some reason we seem to reliably loose the race on Jessie i386 host
installs, but not on Wheezy or other arches on Jessie.
This was tricky to diagnose because the Debian installer main-menu
process appears to buffer the output of things it runs before logging
them to /var/log/syslog, which means the output of "set -x" and the
actual affect of the commands (e.g. in the kernel messages) can be
presented in very confusing orders. Hence this patch also adds
extensive use of logger(1) to record what it is actually doing at the
time it does it. These logs include the pid of the command too since
main-menu only logs its own pid, not that of the subcommand which
gneerated the output.
Lastly this patch adds an explicit test that each device it touches is
actually still a block device afterwards.

Executive: Delay releasing build host shares by 90s
When a build job finishes, the same flight may well want to do a
subsequent build that depended on the first. When this happens, we
have a race:
One the one hand, we have the flight: after sg-run-job exits,
sg-execute-flight needs to double-check the job status, and search the
flight for more jobs to run; it will spawn ts-allocate-hosts-Executive
for the new job, which needs to get its head together, parse its
arguments, become a client of the queue daemon, and ask to be put in
the queue.
On the other hand, we have the planning system: currently, as soon as
sg-run-job exits, the connection to the ownerdaemon closes. The
ownerdaemon tells the queue daemon, and the planning queue is
restarted. It might even happen that coincidentally the planning
queue is about to start.
If the planning system wins the race, another job will pick up the
newly-freed resource. Often this will mean unsharing the build host,
which is very wasteful if the releasing flight hasn't finished its
builds for that architecture: it means that the next build job needs
to regroove a host for builds.
Add a bodge to try to make the race go the other way: after a build
job completes successfuly, do not give up the share for a further 90
seconds. (We have to use setsid because sg-execute-flight kills the
process group to clean up stray processes, which this sleep definitely
is.)
A better solution would be to move the wait-for-referenced-job logic
from sg-execute-flight to ts-hosts-allocate-*. But that would be much
more complicated.

Each "condition" is a new module in the Osstest::ResourceCondition

arguments (split on ':') and stored in $hid.
When allocating for each candidate host the object's ->check method is
called giving $restype and $resname and will return true or false
depending on whether the given host meets the condition.
Only a single condition is implemented here "PropMinVer" which
requires that a given property on the resource has at least the given

cr-ensure-disk-space: Look at referring flights
Previously the flight to delete was simply the one with the lowest
flight number. Now we sort flights not by their own flight number,
but by the highest flight number of any referencing flight.
This means that flights whose builds are being reused are kept as long
as the reusing flights.
This almost-entirely fixes a largely-theoretical race in the way
cs-bisection-step works (where the flight's logs and build outputs
might be deleted between the setup and execution of the referring
flight).
A smaller race still exists because the stash check in
cs-bisection-step occurs before the being-created flight is visible to
other db clients. We will have to fix this by taking the flights
lock.

ap-push: Use refs/heads/ for destinations
When the destination is a branch, specify refs/heads/ explicitly.
This makes ap-push work even if the ref does not yet exist on the
destination.
There is no functional change for an existing installation pushing to
an existing branch. But for a hypothetical new installation, this
would be necessary.
And, more relevantly, when new "branches" are invented, the use of an
existing ap-push case as a template will generate a new case which
creates the branch as is necessary.
I leave the more complex osstest case alone. It's not clear to me
whether the destination ref not existing is an installation problem of
such severity that indeed ap-push should fail.

Also you can say AP_FETCH_MEMO_KEEP=1 to make it reuse old
information, which is useful for making comparisons.
For a further speed improvement, one can use `eatmydata'. This is not
the default because it risks corruption of `standalone.db' which is
used for other purposes too. Add a comment about possibly improving
this.

standalone: Set very long SQLite3 busy timeout in Perl
Without this, big standalone-generate-dump-flight-runvars jobs may
trying to serialise so much work that SQLite3 times out. And we are
about to introduce an optimisation which makes this much more likely.
In standalone mode we probably don't care much about this timeout at
all. (It might even be that the user is using sqlite(3) and has
effectively locked the database interactively for an extended period.)
We would prefer to rely on the user to stop anything that seems to
have become stuck. So set the timeout to 10ks.

standalone: Do not blunder on after errors
./standalone's with_logging function would _log_ errors, but it
wouldn't exit immediately. As a result, the script would blunder on.
Normally it wouldn't do very much more since most of the with_logging
calls are the last thing it does - but the exit status would be wrong
(0, from echo).
As a result, for example, standalone-generate-dump-flight-runvars
would never properly report make-flight failures.

Executive: Abolish use of the `configdb'
This was a database used by networking infrastructure on the
now-obsolete XenClient network in the Citrix Cambridge office (which
used some management tools developed by Mythic Beasts).
The production database in Cambridge no longer has the configdb, and
both instances have `HostDB_Executive_NoConfigDB 1' in the
configuration. We think it very unlikely that anyone has as similar
arrangement.
Remove all the code for accessing this database. We leave the config

are not immediately updated but which use their site's official
production-config. They can be deleted later.

But cs-bisection step foolishly assumed that the --graph-out argument
did not contain any shell metacharacters. Fix this.
Specifically:
* Change invocations of perl's open to use the 3-argument form
* Change invocations of system to pass individual arguments rather
than constructing a shell script fragment and relying on the shell
to split it up.
* In particular, in the png processing pipeline, use the "sh -ec
<script> x <arg>..." technique to pass the input and output
filenames in a way that does not expose them to the shell's parser.
To avoid making this code more tangled than it already is, also
break out the construction of what is now $scriptlet.
* Escape metacharacters in the URIs we put in the html output.

crontab-cambridge: Change the days when we run a given distro-debian suite
The weekly CD images which are used by the snapshot flight are
generated Sunday-Monday, so running that on a Saturday as we have been
doing ensures that it will take at least two iterations/weeks to get
any issues fixed.
Also the current ordering of the existing releases made it hard to
decide where to insert a new release (e.g. Stretch).
So reorder as:
- Run the Sid daily run on a Monday
- Run the Snapshot run on a Tuesday (to pick up the weekly builds
from Monday)
- Run Squeeze on Wednesday and continue with newer releases
chronologically from there.
New releases can then be added at the end (wrapping the days).
Also add some blank lines to aid clarity.

ts-xen-install: Rewrite /etc/hosts to comment out 127.0.1.1 entry
Debian creates an entry such as:
127.0.1.1 lace-bug.xs.citrite.net lace-bug
This causes local lookups of the FQDN to get 127.0.1.1, which is
unhelpful if you are looking for an address to bind to and were hoping
to get the public IP address, as libvirt does on the target host for
migration.
Here we remove (actually, comment) any 127.0.1.1 line in /etc/hosts.
This means that lookups of a hosts own name (fqdn or just dn) now rely
on DNS, which may not be ideal. However for a host which uses DHCP I'm
not aware of a way to keep /etc/hosts up to date with the actual IP
address the machine has. In our infra the test host IP addresses are
all static, but I don't think we want to rely on at any more that we
already do.

cambridge: arrange to test each new baseline
Provide a new cr-daily-branch setting OSSTEST_BASELINES_ONLY which
causes it to only attempt to test the current baseline (if it is
untested) and never the tip version. Such tests will not result in any
push.
Each new baseline is tested exactly once (i.e. we aren't repeating
hoping for a pass), hence the correct revision is just the one tested
by the last run on the branch.
Add a cronjob to Cambridge which runs in this manner, ensuring that
there will usually be some sort of reasonably up to date baseline for
any given branch which can be used for comparisons in adhoc testing or
bisections.
This will also give us some data on the success of various branches on
the set of machines in Cambridge, which can be useful/interesting.
