Antoine Lambert requested to merge anlambert/swh-lister:pattern-improve-max-pages-handling into master
Instead of fully consuming the get_origins_from_page generator into a list and truncate it, prefer to consume the generator origin per origin and abort the process when the max number of origin per page is reached.
Indeed some non trivial listers like the cgit one can perform costly processing, HTTP request for instance, for each origin in a page. So better not consuming the full generator in a row to avoid such side effects.
Before that change:
