For one, when using confluent expressions, induce {} to be an error to
trigger an error for someone trying to xargs something.
Another is to add warnings when clear does something deliberately, but
is something that might surprise a user, steering them toward
what they possibly might want to do instead.
When doing pxe and the noderange of the candidate managers fails,
try again without validation in case the user omitted collective members
from nodelist, but still used ',' to enumerate them.
Reap ssh-agent to avoid stale agents lying around.
Remove nuisance warnings about virbr0 when present.
Do a full runthrough as the confluent user to ssh to a node when user
requests with '-a', marking known_hosts and automation key issues.
For relay agent options, preserve and echo back the option,
needed for certain environments.
Also, it turns out that for whatever reason on some platforms, iPXE's
proxyDHCP logic can't seem to get a reply. In this scenario,
provide the filename in the DHCP offer without waiting for proxyDHCP.
This change may be worth evaluating more broadly, but may carry risk of not working
right with unmanaged DHCP servers.
The code was comparing two string constants, instead of
a variable to a constant. Correct the problem to enable
the preflight checks to work as intended.
Add capability to fingerprint media without doing a full import (/deployment/fingerprinting/)
Add fetching the profile info as json under the /deployment/ api.
Prepare to support custom distribution name on import
Whether due to the management node or node IP addresses,
check if deployment can reasonably proceed using IPv4 or IPv6,
and give a warning with some suggestions to check.
Also, add nodeinventory <node> -s as an example resolution for missing
uuid.
This opens the door for normalized common sensors
for clients that care about the semantics but
cannot keep track of inconsistent sensor names from
implementation to implementation.
Unfortunately, apache can get a bit odd over how it
reports a non-viable open socket for keepalive, which
can happen in certain windows.
Disable the keepalive feature and take some performance penalty in
browsers for the sake of more consistent return behavior and
fewer idle greenthreads doing nothing.
The yaml python default behavior is 'pure python' and is
tortuously slow.
As a test, yaml dump of a 17,000 element list took 70 seconds in default configuration.
Opting into the C functions, that time comes down to 10 seconds, a
nice and easy improvement for generic yaml.
For dumping a simple dumb list (e.g. the nodelist for ssh), a special
case yaml-looking result is done, which hits 0.4 seconds on that same
test. So this special case is added to nodelist, which can be very long
and very in demand at the same time.
