Forgejo fills up hard drive with repo-archives (piefed.jeena.net)

Ugh, apparently yesterday a bot visited my Forgejo instance and queried everything, which caused Forgejo to create repo archives for everything. Git on the instance is 2.1 GB in size, but the repo archive filled up everything and is 120 GB. I really didn't expect such a spike.

That meant that it filled up the whole hard drive and the server and all the services and websites on it went down while I was sleeping.

Luckily it seems that just deleting that directory fixes the problem temporarily. I also disabled the possibility of downloading archived from the UI but I'm not sure if this will prevent bots from generating those archives again. I also can't just make the directory read only because it uses it for other things like mirroring, etc too.

For small instances like mine those archives are quite a headache.

Are you saying if someone (such as a scraper) tries to download a snapshot, forgejo makes a disk file containing the snapshot, sends it, and keeps it around forever? That sounds crazy to me and I'd open a bug or try to fix it.

It makes a zip file and a tarball, and keeps them for cached for other people to download in the future.

Ok so it's just a matter of limiting the cache size.

There is no setting like that, at least I can't find it.

I think you should open a Forgejo issue requesting a cache size limit option. It seems like quite a big problem if bots can fill up your hard drive like this without you setting a limit on all data used by Forgejo (when, for single-user instances, you probably only want to limit archive size or size of any data the public can create, not the size of your own repos)

Ok, there was one issue already and I added my comment to it: https://codeberg.org/forgejo/forgejo/issues/7011#issuecomment-7022288
