There is no ipmi command for a bmc hostname, so get_hostname falls back to the
DCMI management controller identifier. A bmc that does not implement the DCMI
group at all rejects that with "invalid command", which was handed to the caller
as if the request had been bad: nodeconfig <node> bmc read seven fields
correctly and then reported "Error: Invalid command", and the api answered 500
Unexpected error.
Route every DCMI request through one helper that turns "invalid command" and
"command disabled or unavailable" into UnsupportedFunctionality, so the
identifier, the asset tag and the hostname all report a platform that cannot do
this rather than a fault. Where the caller asked about a hostname, say that
rather than naming DCMI.
The whole group read still ends in one error line, because an operation a
platform cannot perform and one that failed are the same message to the client.
That is worth separating, but not here.
handle_users iterated get_users with async for while the same call is awaited
a few lines below, so listing the users collection, and creating a user,
raised a TypeError about a coroutine having no __aiter__. list_inventory in
the redfish plugin had the mirror of it, awaiting an async generator.
get_extended_bmc_configuration is called with hideadvanced but the ipmi chain
never accepted it, so the extra and extra_advanced resources raised a
TypeError; thread the argument through instead.
A user slot the bmc refuses to describe no longer takes the whole user list
with it: one MegaRAC slot answered Invalid data field for good after an
account was deleted, which broke every user operation.
Housekeeper dates from when this work was a blocking select loop. Under
asyncio the event loop is already that place, and a thread around it takes a
captured loop reference, a scheduling step before the thread starts, and a
daemon flag, only to sit waiting on a coroutine that never returns with no way
to stop it. A task runs on the right loop by construction and cancels. The
loop is looked up before the coroutine is built, so calling this without one
raises rather than stranding it.
Nothing in this tree used the class. Out of tree callers need
start_housekeeping() instead, and gain the ability to stop it.
Command.eventloop called wait_for_rsp with no timeout. With nothing waiting or
being kept alive there is no deadline to derive one from, so it returns
without suspending and the loop runs flat out, measured at over 100000
iterations in two tenths of a second.
MAX_IDLE gives it something to wait on, as a ceiling rather than a fixed
delay: real deadlines still shorten it and an arriving packet still ends it
early.
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 the channel access raw command, the TSMA remote media settings
requests, and the XCC3 volume creation responses. These calls returned
or unpacked coroutine objects, breaking set_channel_access, TSMA
virtual media attach, and RAID volume creation at runtime.
Drop python3-eventlet from the Ubuntu Noble build Dockerfile. Clean up
remaining greenthread/greenlet terminology in comments across aiohmi
IPMI modules, consoleserver, macmap, and the IPMI plugin. Remove a
commented-out GreenPool reference in macmap.
