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.
This will take care of padding when
padding is consistent across a range.
However, we still have a problem with a progression like:
01
02
...
98
099
100
Where numbers in the middle start getting padding unexpectedly without a leading digit.
For one, shorten the DNS timeout, if the DNS server is completely out, give up quickly.
For another, if a host has a large number of net.X.hostnames, the sequential nature
was intolerable.
Have each network be evaluated in a greenthread concurrently to serve
the DNS latency concurrently.
Since the multi-iterator ambition is out,
ditch the expensive set wrangling step.
Now the procedure is:
-Suck nodes into groups, as possible
-Separately for groups and nodes:
-Sort the elements
-Chunk the elements based on 'non-numberical' situation matching
-analyze the iterators to apply [] to shorten the name
-Multi-iterator will cause a discontinuity, and a new ',' delimited name gets constructed
There's too many cases that can go wrong.
Note that with this lower ambition, it would be possible to
significantly streamline the implementation.
Notably, the 'find discontinuities' approach
was selected to *try* to
support multiple iterators,
but since that didn't pan out,
a more straightforward
numerical strategy can
be used from the onset.
The info is hard to put together client side, but
supremely easy server side.
Provide a nice call to
get the layout for a noderange, similar to (but better than) current
GUI code.
Now GUI can get a nice canned JSON
description of the layout.
