I'm filing this bug to remind myself (and others) that britney never
cleans up its autopkgtest-results.cache file. Today I used an
out-of-band script to reduce the file a bit (from 529M to 50M), but
britney should do that somehow by itself.

As far as I understand, this isn't so much an issue for Ubuntu because
they start over again with each release. IIRC we could do that as well
as it would be just a bit more churn at the start of the release, so
it's probably smarter to drop results of versions that don't exist
anymore in the involved suites.

(Ugly) Code used
elbrus@respighi:~$ cat bin/strip-britney-autopkgtest.cache

ref_time = round(time.time()) - 150 * 86000

with open('/home/release/britney/state/autopkgtest-results.cache') as f:
    test_results = json.load(f)

test_results_new = deepcopy(test_results)


for (trigger, trigger_data) in test_results.items():
    for (src, results) in trigger_data.items():
        for (arch, result) in results.items():
            if result[3] < ref_time:
                del test_results_new[trigger][src][arch]
        if len(test_results_new[trigger][src]) == 0:

This has been fixed earlier this year.
