Hello everybody, I’m having an issue with a WebkitGTK-based app that I’m
building where I am unable to set the HTTP proxy settings through the
http_proxy and https_proxy environment variables because the system Dconf
settings take precedence over them. In an environment where Dconf is not
present, i.e. a https://github.com/indigo-dc/udocker container, I can confirm
that the environment variables work perfectly, but on my Pop!_OS ( Ubuntu )
20.04 system, the Dconf settings override the environment variables.
I would be fine setting the proxy settings through Dconf, but the issue is that
the username and password authentication settings from Dconf are not respected,
so there is no way to configure my username and password through the system
dconf settings. The username and password work fine when set through
environment variables though. Normally even this wouldn’t be an issue much
because Webkit would show the proxy authentication prompt dialog, but this
doesn’t work because in my app, the request that needs the proxy authorization
is a cross-origin request:
CONSOLE ERROR Blocked
https://api.jujucharms.com/charmstore/v5/~katharostech/lizardfs-gui-0/icon.svg
from asking for credentials because it is a cross-origin request.
So this gist is that I either need to be able to do one of three things, in
order of preference:
Be able to make the proxy environment variables take preference over the dconf
settings or otherwise disable the use of dconf for the proxy settings
Be able to have webkit respect the /system/proxy/http/authentication-password
and /system/proxy/http/authentication-user dconf settings
Be able to get cross-origin requests to prompt for proxy authentication
