Fontconfig fails to generate valid cache files

hussam · 2019-10-30 10:27:34

Hello. I have an issue with fontconfig. it says invalid cache files and deletes them all when I do fc-cache.
All my fonts are installed from the repositories using pacman.
How can I tell what is happening?

What commands are you running exactly, and can you share the output you get?

On my system here, I just tried running these two command lines here:

sudo fc-cache -f -v
fc-cache -f -v

The second one printed something interesting:

...
/home/user/.cache/fontconfig: invalid cache file: 78939b3d439f2873b9ab995cd837dd66-le64.cache-7
/home/user/.cache/fontconfig: invalid cache file: 158c65c810c0d352a587f5be66058e87-le64.cache-7
...

These messages didn't get printed again when I ran the command a second and third time. They were only printed the first time.

What does your /var/cache/fontconfig/ contain?

This is what it printed here

and the font cache dir is empty.
I'm not sure if that has any side effects.

Ok, I figured out a way around this.
Instead of typing 'su' before installing a fonts package or running fc-cache -v -f, I typed "su -" and fontconfig no longer creates corrupt cache files.

This issue is back after the last two fontconfig package updates.
Any idea?
I reported it upstream https://gitlab.freedesktop.org/fontconf … issues/311
but I'm not entirely sure it's a real bug. perhaps it is something I messed up locally?
