While we still use this archive.sh script, dbscripts has recently also
be extended to populate the archive continuously. So uploading could be
integrated there with a queue file and a background job that performs
Alternatively the uploader could be kept standalone and just adapted to
run more often and to maintain its own database/list to know which
packages have already been successfully uploaded and which haven't. I'll
call this "state database". Then we could run it every hour or so via a
systemd timer and it could upload all new and all failed packages. One
thing I'd want to have in this context is that the uploader should exit
with an error to let the systemd service fail if a package fails to
upload multiple times. I think I'd actually prefer this to be standalone

Avoiding load spikes for archive.org certainly sounds like a good idea
and for us it's easier to monitor and maintain services that run more

This could use the state database I mentioned above. As for the
implementation of such a database, I'd suggest sqlite instead of rolling
your own text based list or whatever. It's fast and simple, but you get
all the fancy stuff, like transactions, for free. You also don't have to
deal with recovering the database if the script crashes. sqlite just
rolls back uncommited transactions for you.
Would you be interested in adapting the uploader like this and making it
an automated service? If you're interested I can help with the
deployment part and provide feedback on the scripting side. If you want,
we can also discuss this on IRC.
