[dpdk-ci] [PATCH v4 10/10] tools: skip the IDs we already fetched

[Ali Alnubani]

To avoid calling 'callcmd' more than once for an ID, which can happen
if a Patchwork ID was created between recording 'date_now' and fetching
the API, store the IDs we already fetched in a file and don't run 'callcmd'
again for any ID that exists in the file while keeping the number of
entries less than 1000 in that file.
