Comment 4 for bug 314621

I have no idea where CodeImportResult rows get created and am not familiar with the tests, so I doubt it is easier for me to do.

I think all that requires being done is doing 'codeimport.log_file.expires = now + timedelta(days=60)' after creating the codeimport object.

Or if you really do want to ensure preservation of the 'last N', do the
following after creating a codeimport:

store.execute("""
UPDATE LibraryFileAlias
SET expires = CURRENT_TIMESTAMP AT TIME ZONE 'UTC' + interval '60 days'
FROM CodeImport
WHERE
    LibraryFileAlias.id = CodeImport.log_file
    AND expires IS NULL
    AND CodeImport.branch = %s
    AND CodeImport.id NOT IN (
        SELECT id
        FROM CodeImport
        WHERE branch = %s
        ORDER BY id DESC
        LIMIT %s)
""" % (codeimport.branch, codeimport.branch, N))

Oh - and me doing the equivalent manually for all the historical records.
