I haven't looked yet but I suspect it'll probably be a wash, mostly. If
anything it's likely slightly negative because the new installer itself
hard requires webkitgtk, so we can't really do anything to finesse that
requirement any more. With the old installer, we could maybe try and
figure out some way of being able to show the help pages without
needing yelp/webkitgtk. Since the new installer itself needs webkitgtk,
seems like there's no way we're getting rid of that ~40M compressed.You should also try to do this - remove webkitgtk and yelp packages and add firefox, because that's what the web based installer should/will use in the end - see https://bugzilla.redhat.com/show_bug.cgi?id=2142779. We already had a meeting with Anaconda dev and told him to use Firefox instead of WebKitGTK for the web installer - due to resources that are internally (and frankly in upstream as well) allocated to WebKitGTK.
While the currently published Web UI preview images use GTK3 WebKit to show the Web UI locally, I did some local image build using Firefox in kiosk mode (eq. using the --kiosk CLI option):
- generally works fine
- performance is good, does not exhibit the high CPU consumption for UI animations GTK WebKit has on VM with no GPU acceleration
- no header bar ever shown (which is what we want at the moment)
- no right click context menu, no right click copy paste menu (this is usable, be if possible we would like to show the web debug console option if anaconda runs in debug mode & the missing copa paste menu could be seen as a usability issue for users)
- adds about 80 MB to image size (so about +40 MB in comparison to GTK WebKit as far as I can tell - *very rough/preliminary numbers*)
- the memory consumption (measured at end of the installation) seems to be slightly higher when compared to GTK WebKit
BTW, just an idea - would a "Firefox minimal" build make sense ? I don't think we (and other projects in need of a lightweight Web View) would ne advanced vide playback support, Web GL, VR support and other features that certainly make the Firefox binaries bigger than necessary for the usecase.
