Support Request Template
What version of phpBB are you using? phpBB 3.3.13
What is your board's URL? not publicly accessible right now
Who do you host your board with? on "bare metal" in data center
How did you install your board? I used the download package from phpBB.com
What is the most recent action performed on your board? Fresh Install
Is registration required to reproduce this issue? No
Do you have any MODs installed? No
Do you have any extensions installed? Yes
What extensions do you have installed? StopForumSpam
What styles do you currently have installed? Carbon
What language(s) is your board currently using? default BE
Which database type/version are you using? MariaDB
What is your level of experience? New to phpBB but not PHP
What actions did you take (updating your board; installing a MOD, style or extension; etc.) prior to this problem becoming noticeable? Migrated from vb3, then manually set/fixed permissions for groups so everything is nice and clean again.
Please describe your problem. PHP runs out of memory on various actions (i.e. most noticeably viewtopic).
We could trace back the cause to auth.php-->acl_raw_data() . Memory usually runs out after the query in line 670++ runs (confirmed by watching the process list in DB as well as dumping queries to error-log).
The last actual query being sent when attempting to view any topic/post before running out of memory (I simply added an error_log to driver/mysqli.php to grab this) is this:Browsing the forums/categories themselves works fine, as does the ACP and everything else.
I'm not quite sure what this function and those queries are supposed to be doing, but as it apparently returns at least one row per user_id and forum_id, that alone means at least 15.6 million results, and that's just one of the queries being performed here.
I did increase the php memory limit to 5GB "for fun", but even that wasn't enough to fit in whatever is going on in that function, and obviously I don't want to ever have even close to 5GB allocated to a single PHP process.
I'd be very happy if someone could explain the purpose of this function and why there's ever a need to get the permisisons of all users for all forums at once in the first place.
And obviously curious about how any ways to fix this mess we've gotten ourselves into.
I assume we're making a fundamental mistake in our setup of permissions or others would have this same issue?
