At this point there is no build entry because we do not yet have the SRPM to determine the NVR from.

You can find the failed build tasks with something like listTasks(opts={"method": "build", "state": [5], "createdAfter": "2021-04-20"}). I would highly recommend a time limited query here.

You might consider only querying the tasks actually.

Note that this will include scratch builds.

I have a proof-of-concept script that runs very similar query

opts['createdAfter'] = args.date
opts['method'] = "buildSRPMFromSCM"
opts['state'] = [ koji.TASK_STATES['FAILED'] ]
opts['owner'] = [ kojisession.getUser(userInfo='releng')['id'] ]

• args.date is the mass-rebuild start
• find failed buildSRPMFromSCM tasks
• started by the releng user
  The output is package names extracted from the dist-git URLs.

Awesome, I will update the ftbfs script.

Thanks @mikem and @sharkcz

Also, @mikem it would be super useful to update the koji api to provide what state numerical values means what.

>>> import koji
>>> koji.BUILD_STATES
{'BUILDING': 0, 'COMPLETE': 1, 'DELETED': 2, 'FAILED': 3, 'CANCELED': 4}
>>> koji.TASK_STATES
{'FREE': 0, 'OPEN': 1, 'CLOSED': 2, 'CANCELED': 3, 'ASSIGNED': 4, 'FAILED': 5}

These are custom enum classes. They convert either way

>>> koji.TASK_STATES[0]
'FREE'
>>> koji.TASK_STATES['FREE']
0

I've added simple PR with example on API page and link to constants/exceptions: #2828
