bug#47092: Icecat sandbox causes issues with fonts in --pure env

[Martin via Bug reports for GNU Guix]

Hello,
whenever I'm trying to run 'guix environment --pure --ad-hoc icecat -- 
icecat' or similar commands in a --container I'm ending up with some 
tofu ugly font fallback box glyphs in the app. However everything works 
fine running 'guix environment --ad-hoc icecat -- icecat'. Moreover I've 
noticed that when I edit the default value of 
"security.sandbox.content.level" from 4 to 2 in "about:config" then the 
problem disappear and the fonts are properly displayed in --pure and 
--container env. I was trying to install all possible fonts, running 
'fc-cache -rfv' and analyze the icecat logs with "MOZ_SANDBOX_LOGGING=1" 
to include blocking paths into the 
"security.sandbox.content.read_path_whitelist" but still I couldn't fix 
this issue with the icecat default sandbox level. Any ideas how to solve 
it in Guix System and what are the side effects of using 
"security.sandbox.content.level=2" in --pure env?

Kind regards!
Martin

Hi,

The example about ’eolie’ adapted to your usecase, does it not work?

See:
<https://guix.gnu.org/manual/devel/en/guix.html#Invoking-guix-environment>


All the best,
simon

Hi Simon,
no it doesn't help in this case and in general eolie package seems to be 
broken because it doesn't work even with the simple 'guix environment 
--ad-hoc eolie --  eolie':

Traceback (most recent call last):

The manual example is:

--8<---------------cut here---------------start------------->8---
guix environment --preserve='^DISPLAY$' --container --network \
  --expose=/etc/machine-id \
  --expose=/etc/ssl/certs/ \
  --share=$HOME/.local/share/eolie/=$HOME/.local/share/eolie/ \
  --ad-hoc eolie nss-certs dbus --  eolie
--8<---------------cut here---------------end--------------->8---

from <https://guix.gnu.org/manual/devel/en/guix.html#Invoking-guix-environment>


Does it not work for you?

Then it should be adapted for your use-case.



All the best,
simon

Indeed, the package eolie is broken; which is another issue–and BTW
thanks for pointing this out.  Back to your initial report about icecat,
what about something like that:

--8<---------------cut here---------------start------------->8---
   guix environment --preserve='^DISPLAY$' --container --network \
     --expose=/etc/machine-id \
     --expose=/etc/ssl/certs/ \
     --share=$HOME/.local/share/icecat/=$HOME/.local/share/icecat/ \
     --ad-hoc icecat nss-certs dbus --  icecat
--8<---------------cut here---------------end--------------->8---


All the best,
simon

It's still not relevant to my issue. To run icecat using your example 
you should change one parameter to 
"--share=$HOME/.mozilla=$HOME/.mozilla" but again with the default 
"security.sandbox.content.level=4" the fonts will be tofued. I think 
once the issue could be fixed with simpler command, i.e. 'guix 
environment --pure --ad-hoc icecat -- icecat' than it would be easier to 
port the solution on the --container case.

Kind regards!
Martin
