This had to be a misconfiguration or something...

I was attempting to update the linux-pds package today, and got this wonderfully confusing error.

The `config` file is 250.8KiB, and thus triggered this error...

This break pushing any commits greater than 250KiB... which would include some patches that can easily exceed that weird limit.

Terminal output:

Oh yes, clearly very critical bug to have a configured limit perform as intended. I'm not sure why this is confusing? Disappointing, sure. But it's pretty obvious what this means.

If you have a 250KiB+ size patch file, you're doing something very wrong.

Kernel configs are I think the only thing that ever runs close to the limits, yet remains valid to upload to the AUR. It's very much the minority of packages.

The size of a kernel .config slowly creeps up. We probably need to bump the limit as part of housekeeping. But it's hardly a misconfiguration to have a limit.

250KiB is just too small. What if there are shipped patchsets that exceed this limit?

As a stopgap, I'm just going to compress the config file, because I have no choice right now... *shrug*

Can confirm this is an issue for kernel packages. This currently denies me from updating the linux-hardened-git package in the AUR as the kconfig exceedts the limit now. Would be neat to get this raised.

Can't raise PRs against Archlinux GitLab yet but something like this patch would solve it.

The patch is applied and tested. Works just fine and you now have 500k to work with. Enjoy.
