During today's StopForumSpam production config deploy (T273220), @Reedy and I noticed that the updateDenyList.php maintenance script, when run from mwdebug1002, didn't seem to populate wanCache with every IP value from the configured stopforumspam.org deny list (https://www.stopforumspam.com/downloads/listed_ip_90_ipv46_all.gz). It appears to have populated the cache with 66,454 IPs while there are 194,719 IPs within the stopforumspam.com deny list. So:
- Is there a bug in the maintenance script that's limiting the import in some way? Maybe verify on beta, where the extension has been deployed for several months.
- Is there some hard cap in production for cache imports that we're unaware of? Should these be batched in some way then?
