Implement support for running on Wayland through Weston #5401

Conan-Kudo · 2024-01-15T02:02:22Z

This implements rudimentary support for running Anaconda on Wayland using the Weston compositor through XWayland. This support also includes simple auth-less VNC remote access, though authenticated VNC support requires extra effort since Weston's authenticated VNC support uses TLS certificates and we do not have a good way to plumb that through right now (more info in weston-vnc(7)).

Without understanding the problem domain, LGTM so far.

pyanaconda/core/util.py

+    argv = ["weston", f"--config={weston_config_file}", "--log=/tmp/weston.log",
+            f"--socket={WAYLAND_SOCKET_NAME}"]


We aren't using f-strings anywhere else. Not sure if it means they can't be used at all, though.

f-strings were added in Python 3.6. I think it's pretty reasonable to state that we're probably not going to be running this Anaconda codebase on something older than that, since Python 3.6 is what RHEL 8 shipped with. I can certainly change it, but I liked how it make this easier to read.

Sure, it would be possible to use f-strings on the platforms we care about, it has been more a question of team policy or consistency so far not to use them in the Anaconda code.

pyanaconda/core/util.py

+            sock.close()
+            wl_status.started = True
+            return wl_status.started
+        except Exception:


Can this be more specific than just Exception?

In theory, I could, but I have intentionally not done so because I want it to happen in any exception case. It's merely for shorting the loop to iterate on the timeout.

Conan-Kudo · 2024-01-17T14:06:11Z

@VladimirSlavik, @jkonecny12, @M4rtinK: do any of you know what I'm doing wrong with the Autotools definition to add the PAM file? I'm not sure how to fix it...

Conan-Kudo · 2024-01-17T15:09:00Z

Ah, I figured it out now, and it looks like the package builds are going now.

@Conan-Kudo Kudos on the awesome job, this contribution is in great state and I see it already uncovered some issues (Lorax templates)! 🌟

However, I've got a few thoughts about merging that I wanted to share.

Our team's got some recent "capacity challenges" post you might wanna check out: Check the post here. It paints a bit of the picture we're dealing with right now.

Here's the thing – about Weston, there's some uncertainty on downstream support (probably not at all), and keeping this as an upstream only change, means we are without the QE team on board, so this could create a headache for us maintenance-wise. Plus, we're in the trenches porting Anaconda to XWayland already, so probably there is some conflicting areas in your work with what @M4rtinK is currently working on.

I'm thinking it might be wise to keep this open and not merge it for now, aligning it with our current WIP changes towards xwayland but without introducing Fedora only solutions (Weston).

Conan-Kudo · 2024-01-17T19:01:59Z

@KKoukiou In general, I think what I'm working on and what @M4rtinK is working on will not conflict. Changing Anaconda's behaviors as an XWayland application is complementary to this. All this does is make it so that we run Anaconda as an XWayland application and wires up both the default and VNC modes to Weston as a Wayland compositor.

There are separate work items that need to be done to further improve the experience, and @M4rtinK's work is positioned to help here.
