XMonad would crash if XMonad.Layout.Tabbed.Theme.fontName was a series of Xft font names.

Problem Description

Before upgrading packages on Gentoo Linux, the tabbed layout just displayed rectangles instead of chinese characters when I played japanese youtube videos on a web browser.

After upgrade, if XMonad.Layout.Tabbed.Theme.fontName was set to a series of Xft font names, XMonad would just crash. This issue is also reproducible on Manjaro Linux.

For example, if XMonad.Layout.Tabbed.tabbed or XMonad.Layout.Tabbed.addTabs was passed XMonad.Layout.Tabbed.Theme with its fontName set to xft:LiberationMono:size=13,NanumGothicCoding:size=13,ipamincho:size=13,ipagothic:size=13,uming:size=13, then XMonad crashes.

This issue is related to #173

Configuration File

import XMonad
import XMonad.Layout.Tabbed (tabbed, Theme(fontName))
import XMonad.Layout.SimpleDecoration (shrinkText)

main :: IO ()
main = do
  xmonad $ def
    { layoutHook =
        Tall 1 (3/100) (53/100) |||
        tabbed shrinkText def { fontName = theFont }
    }

theFont :: String
theFont = "xft:LiberationMono:size=13,NanumGothicCoding:size=13,ipamincho:size=13,ipagothic:size=13,uming:size=13"

If I press M-Space to switch the layout to the tabbed layout, XMonad explodes.

theFont = "xft:Monospace-13" and theFont = "xft:LiberationMono-13,NanumGothicCoding-13,ipamincho-13,ipagothic-13,uming-13" don't crash XMonad.

According to my tests, if fontName is a list of Xft fonts, only the first font in the list is used.

Presumably there's an issue with our FFI to Xft. Can you find the log output (virtual console, ~/.xsession-errors, or possibly somewhere in journald)? m not sure anyone has looked at the font handling in X.L.Decoration since arossato lost interest.

On Gentoo Linux, there is /var/log/messages instead of journald. I found nothing in /var/log/messages and /var/log/Xorg.*.log.

With profiling build, I got the following errors, but those errors do not seem to reveal the cause of the issue.

startx.txt
xsession-errors.txt

[geekosaur]

Both of those are crashes in getWindowAttributes, which should not happen unless someone overrode the version requirement for the Haskell X11 bindings.

Arch already did that once, maybe Gentoo decided to do the same thing. :/ That will cause crashes.

[crocket]

Those errors were gathered from a profiling build of stack.
~/.xmonad/build builds ~/.xmonad/xmonad-x86_64-linux via stack.yaml.
Those exceptions do not crash XMonad.
I built gentoo packages with profile flag, but xmonad --recompile didn't produce a profiling executable for the sample config.

Can you reproduce the issue with my sample config?

I'm also encountering this error on Arch Linux (Manjaro). Only specifying one xft font works fine.

[Vonfry]

How about add pango suuport? Its haskell binding may better than xft.

Font fallback was implemented in #646, so I'm closing this
