The issue is there's far more pages than could reasonably be stored: cgit is an old-school server-side renderer and there's a combinatorial explosion of possible pages it could render. The article calculates there's about a quadrillion different pages that could be 'crawled'
replyMost of those pages are going to be identical if not for some very minor differences. You can make it much much cheaper to put together these pages as opposed to the expensive operations it has to do right now.
replyApparently the current implementation is very inefficient by modern standards:

Rather than using Anubis to give the client fake work, maybe the way to go would be to get the client to do the real work in JavaScript? Then the server doesn’t have to do it.
Or, html generation could be very, very fast in the first place. For example, serving static files is usually just as fast as a reverse-proxy cache.
replyInterestingly enough, cgit bills itself as "a hyperfast web frontend for git repositories" [0]. Alas, nothing is fast enough for the bots, it would appear.
he said its fast enough for now actually...
replyThat was my first thought, varnish (vinyl these days) in front of the website should dramatically reduce this as the git repo should be practically static for most of the content.
replyBut there are "cubic bazillions" of possible URLs that are being requested. Even if they boil down to "only" some millions actual commits, their rendered HTMLs are all different.
replyYes, this is very difficult to solve for sites with many URL variations, like git repos and heavily threaded forums. Your cache is always full, but the hit ratio is abysmal.
replyremember, its only difficult for you. at the end of the day its just 7gb of data...
replyno its only difficult for you. and only at this moment... any minute now you will see the way. btw, the OP is just saying "its OK for now". And the OP is just telling us: this is what has been happening... maybe its difficult for OP also, but they didnt say that. they just said their current setup cant handle it. old tech...have a hackathon to solve for this. OP says it's not a problem for him right now but if we extrapolate what he's talking about it's definitely a problem aaaaaaand It's totally solvable, Even with all of the crazy combinations he's talking about it's still solvable. And it's already been solved using patterns we see in streaming services. This is completely hackathonable. but why do we even need to bother with this? The slurpers are the cause of this, and they can cause this problem because of Murphy's Law. well you can only account for Murphy's Law with good architecture or something like that or whatever. Ha ha hackathon.

replyThe cache gets evicted between the times the old commits are revisited.
replyusing the current solution and a cache pattern doesnt solve it, but it is an "affordable" solvable problem. but first we need to ignore OP said its ok for now...have a hackathon to solve for this.

replyi think its only 7gb of data total, therefore there should be a strategy to fully optimize for this deterministic scenario, but instead of caching instead with maybe compiled streaming renderer(s)... but he said its ok for now.. and anyway why should they need to fix anything, the slurp is what sucks. pun intended
replyanyway, I have solved this exact scenario many times in the last 30 years... thanks for the dv.. have a hackathon to solve for this.
