Firmware for a supply or a fan matched no fragment and so was called
core, and nothing could ever answer for misc.
Only the collections that mean one thing are matched by url. A Storage
resource is the subsystem, so its firmware is the controller rather than
a drive, and a Processor is a cpu as readily as an accelerator, so that
one is decided by asking the processor what it is.
The labels are worked out across the whole inventory, since a platform may give
every entry the same Name, so an entry that came back empty would be asked for a
name it does not have and take the naming of the others with it.
Some will not take an image without being told which kind it is, and the
only way to find out was to attempt an update and read the error, which
writes to the bmc before it gets that far.
This bmc gives all three of its firmware entries the same Name, "Software
Inventory", and puts what they actually are in the description. The first
entry took that name, and the two after it fell back to their ids, so
nodefirmware answered with "Software Inventory", "cpld_active" and
"d1dc9e4b" for what are the host, cpld and bmc images.
Decide the labels across the collection rather than one entry at a time,
so a name the platform repeats can be recognised as no name at all. Where
that happens, use a description that does tell them apart, and the id when
even that is shared. A platform whose names are already distinct keeps
exactly the names it had.
The labels are what a caller addresses an entry by, so this also turns
inventory/firmware/all/d1dc9e4b into inventory/firmware/all/bmc_image.
Reading the identify state says plainly when a platform describes no
indicator, but writing it went ahead and patched IndicatorLED regardless.
This bmc has neither that property nor the boolean that replaced it, and
answered the write with an internal service error, which reached the user
as one and the log as a traceback.
Ask the same question the read asks. With neither property present there
is nothing to write, so say so in the same words instead of finding out
from the bmc.
This bmc advertises a Bios resource on its system and answers 404 for it.
Confluent followed the link and passed the bmc's complaint on as an
unexpected error, so a nodeconfig read printed every bmc setting and then
ended with "The requested resource of type named 'Bios' was not found",
and the system half of the configuration was a 500 saying the same.
There is already a good answer for a system that offers no bios settings,
and a link that is advertised and not served is the same thing as far as a
caller is concerned, so give it the same one. The result is checked once
and remembered, including the negative, so this costs one request on the
first ask and nothing after.
A caller asking for fans or energy got nothing from any bmc that serves
the Sensors collection. Those sensors were filed under their redfish
reading type, Rotational for a fan, while the categories are named after
the ipmi sensor types the rest of the code uses, so nothing matched.
Power appeared to work only by coincidence, Power and Current happening to
be spelled the same in both vocabularies.
Translate the reading type as the sensor is mapped, so a sensor means the
same thing whether it came from the Sensors collection, from the older
Thermal and Power documents, or from ipmi. On the bmc this was found on,
fans go from nothing to the 24 tachometers, and temperature and power
already agreed with what the same hardware reports over ipmi.
The fan controls stay out, and cannot be brought in. Their reading type
is Percent, which is also what a battery state of health reports, and this
bmc fills in no PhysicalContext to tell them apart, so there is nothing to
classify them by that would not also drag in unrelated percentages.
IndicatorLED is deprecated in redfish in favour of the boolean
LocationIndicatorActive, so a platform that only implements the newer property
reported no identify state and could not be told to light up. Read either one,
preferring the older where both appear, and write the boolean when that is what
the resource offers. The boolean has no way to express blinking, so a request to
blink lights it steadily.
The led resource shares the same reader, so it gains this as well.
Deleting a user gave up after one attempt and reported why the fallback of
blanking the name failed rather than why the delete did. MegaRAC reports a
timeout for a delete that a second ask completes, so retry, check whether the
account went away, and keep the original error.
Attaching media judged a device free by ConnectedVia, which describes how the
device is wired to the host rather than whether anything is in it. Every
device on this bmc reports a fixed value there, so nothing was ever selected
and the attach reported success having done nothing. Judge by whether an image
is loaded, fall back to the properties when an advertised insert action is not
served, and say so when no device would take the image.
The firmware category was passed to the library and ignored, so core,
adapters, disks and misc all returned the same full list. Classify by what
each entry is related to, and answer only for core when a platform says
nothing about where its firmware belongs.
reseat_bay reached for a hardcoded Nvidia action on Chassis_0, so it failed
with a not found for that url instead of saying reseat is unsupported.
Five resources called methods that do not exist on the redfish client, so
each answered with an internal error naming the missing attribute: the leds,
the management controller identifier, the domain name, the remote kvm licence
and the alert destinations. Implement the first four from the manager network
protocol, the graphical console and the chassis indicator.
Alert destinations stay unimplemented on purpose. Redfish describes where to
send events with EventService subscriptions, which is a different model from
the numbered PET destinations this resource was built around, so say so and
drop the code that could never run.
The location resource fetched its data and discarded it, so a read produced
no output whatsoever.
Reads are cached for thirty seconds and a write did not invalidate anything,
so setting a boot device or the identify state and then reading it back
reported the value from before the write for up to half a minute. A write can
change documents other than the one written, an action url not being the
resource it acts on, so drop the cache rather than one entry.
MegaRAC refuses a PATCH with no If-Match header, so setting the bmc hostname,
ntp, the bmc network configuration, a location and ejecting media all failed
with a precondition error. set_identify already passed etag=*; do the same at
the call sites that did not, including the firmware push busy flag.
get_identify indexed the sysinfo method object rather than awaiting it, so
reading the identify state raised a KeyError naming a bound method on every
redfish system. Read the indicator from the chassis that owns the physical
led, since some implementations leave the copy on the system stale, and say
plainly when a platform does not report one.
The generic get_description took no fishclient while every other handler and
the caller pass one, so the description resource raised a TypeError on any
non Lenovo bmc.
Apply ruff's safe autofixes.
The changes are mechanical and behaviour-preserving. Issues fixed:
- F401: remove unused imports.
- F841: drop unused local variables and assignments, including discarded
await/return values, unused "except ... as e" bindings, and unused
"with ... as name" targets.
- F541: remove the f prefix from f-strings that contain no placeholders.
- E711: compare against None with "is"/"is not" instead of "=="/"!=".
- E712: test truthiness directly instead of comparing to True.
- E713: use "x not in y" instead of "not x in y".
- E714: use "is not" instead of "not ... is".
- E731: convert lambdas bound to a name into def statements.
- W291/W293: trim trailing whitespace on touched lines.
Await OEM sensor, NTP, retry, and firmware-update operations that otherwise returned or discarded coroutine objects. Return the initialized energy manager for FAPM systems and update stale utility entry points to use asynchronous Command factories.
