From what I understand, this issue could be because of multithreaded CPU. Go runs the http on another goroutine. This is a thread with more info: https://github.com/golang/go/issues/26698

How To Reproduce Just run on a multithreaded CPU.

EliasStar commented 2 years ago

I have DashD running on a RPI 0 which has a quad core cpu. Also DashD doesn't use net/http. The error originates from the webview library (probably unsafe pointer deref in c -> seg fault). Could you try and start DashD without the default_url flag?

mishoboss commented 2 years ago

Same result. Unfortunately. Any other idea how to debug it?

EliasStar commented 2 years ago

I have a suspicion as to what may be causing it. I have seen over at the webview repo that someone was experiencing crashes when the window was being created in a separate os thread. It could be that Go decided to give the display goroutine a separate thread on your platform as opposed to running it on the main thread on my RPi. The webview library is in general pretty unstable and I'll maybe replace it if i can't find a solution which satisfies the architecture of DashD.

mishoboss commented 2 years ago

Is there an easy workaround that won't take a lot of time? I would really like to run the daemon soon.

EliasStar commented 2 years ago

A fix is in progress. Unfortunatly there is no user workaround exept using another CPU/board which might behave differently. However I have already made some changes, which you could try. I haven't tested them yet so report back if they don't work. Here are the patched binaries

Unfortunately nothing has changed.

Actually, I get goroutine 1 [syscall, locked to thread]: now:

EliasStar commented 2 years ago

I have seen just now that the crash occurs in SetTitle which I haven't touched in my patch so no wonder it didn't change anything. Here is another version you can try.

mishoboss commented 2 years ago

Thanks, it's definitively a step forward. However I get Could not connect: Connection refused again, just no additional errors:

image

I tried with the 9090 port as well, just to be sure.

mishoboss commented 2 years ago

If I disable the display - -display_enabled=false the error is gone, but of course no website is shown either. This definitively comes from the WebKitGTK.

EliasStar commented 2 years ago

Can you post the output of ldd /usr/local/sbin/dashd?

So I just figured out that the error happens because WebKit can't connect to your Xserver. Make sure your Xserver is running and you launch DashD with DISPLAY=:0 set as environment variable or in a terminal emulator running in an X context. If you use the recommended setup from the README it should just work™.
