Hi Chromium packagers,

I did a bunch of work years ago in https://crrev.com/305314 and
https://crrev.com/305348 so Chromium can run on Linux distros with
either libudev.so.0 or libudev.so.1. It's been a while, so I would
like to undo my work. At the very minimum, I would like to remove the
checks for libudev.so.0. I would also like to remove the dynamic
loading mechanism to further simplify things.

Before taking any actions, I'm wondering if anyone is still running
modern Chromium on a Linux distro that uses libudev.so.0. I think RHEL
6 ships with libudev.so.0, but support for RHEL 6 looks to be at the
end, assuming I read RedHat's lifecycle info correctly.

Not Ubuntu. The oldest supported release is 16.04 (xenial), and it has
libudev.so.1.

Yes, that's true.

And that's true as well. It will go EOL by the end of November 2020. But we will rebase to the newer version until that happens. So if you could target a Chromium major version that won't be in stable channel at that point, we would appreciate it. According to https://www.chromestatus.com/features/schedule it probably will be Chromium 88.

Bye,
Tom (Red Hat)

Chrome itself still supports Trusty (14.04), so we'd still need to be careful if it only has .0.

Trusty also has libudev.so.1 (systemd 204), so that should be fine.

Thanks for the feedback so far. I'll wait and see if anyone else
chimes in for other distros.

I have no plans to work on this immediately, so this will definitely
be for Chromium 88 or later. Just wanted to get the conversation
started.

couldn't we use UMA for this sort of thing ?

Hi Lei

The Slackware platforms for which I provide Chromium packages (latest stable aka Slackware 14.2, and also the development release aka slackware-current) all ship libudev.so.1.

Cheers, Eric

On another issue, we found base::debug::DumpWithoutCrashing() gave us
the feedback we needed without the overhead of adding an UMA. I've
filed https://crbug.com/1237497 for this work.
