> they're not hard if you don't overengineer them. 10-20 lines of bash per test (bash is gross for anything that needs proper error handling, but that's what I'm still using), bring up a configuration, do some basic network connections/write some data in fio verify mode, verify that nothing explodes and there's no errors.

They're a lot harder when you're talking about non-trivial network configurations that necessarily involve external kit that also needs to be properly configured.

That's all simulatable in VMs, exactly the same as I do for filesystem testing.

Then it's no longer "10-20 lines of bash code"

I already built it for you: https://evilpiepirate.org/git/ktest.git/

This link throws a 404.

yeah I just had to flip off cgit, thanks to - you guessed it - too much AI crawler traffic

so until we get anubis going, there's a github mirror: https://github.com/koverstreet/ktest/

I took that opportunity to look at my own cgit traffic. Yikes. Anubis downloaded and installed, nginx config adapted. Took ten minutes. "git clone" still works, no config modification required.

I do wonder how long it'll take these *censored* to notice that each request now results in an identical 12-kByte result (1.2 on the wire, it's compressed) … in the meantime I bet we're going to get a veritable ton of random search hits (and AI chat replies) for basically anything that smells like Anubis' challenge page.

What was that curse again … "may you live in interesting times".

NB my log shows a marked increase in the number of AI bot requests since yesterday, which is not at all surprising: Anubis replies a whole lot faster than cgit.

Yeah, it's gotten really bad. I used to be able to block them with a 10 line script that scraped the apache log, sorted IPs by number of accesses, and iptables blocked the ones that were over some silly number.

Now, they're all coming from different IPs - it's only a few accesses per IP - and the load was so bad the git fetches for the CI workers were unable to run. It ground my test infrastructure to a halt!

They're a bloody menace.

Although I'd also really like to know why git is so ridiculously memory hungry.
