Yes, it is, but I'm not sure it's better to split up into parts that cannot be tested on their own. Furthermore there is very little or no logic in it, mostly build stuff and a bit of refactoring. However I can split it if you think it is necessary.

Going to fix the other issues.

So why does the networking process need EFL stuff, when we basically just use libsoup for networking? Why not just use glib+libsoup and share this with GTK?

Old story, and I don't remember exactly.  This is copied in a lot of places, so are the fnctl calls. Maybe it's better to move it into a helper anyway.

Hm, it is somewhat trivial that this file should be there for every port.

RunLoop is different on EFL, it uses ecore, I don't think we can get rid of that.

Not even if it is a separate process/build project... can't you not just use the glib based one from gtk? It will probably perform better than the currently integration between ecore and glib used by default.

[Dan Winship]

yeah, what he said. If you use RunLoopGtk rather than RunLoopEfl, you shouldn't need to initialize any efl stuff. (And RunLoopGtk, despite the name, does not actually use gtk, just glib. Though maybe you'll need to copy it to a new file to avoid pulling in other webkitgtk stuff...)

Then why the hell we have RunLoopEFL? And how should I manage to get a copy of the lib that contains the gtk implementation, while the one that the ui and the web processes links to contains the efl one? Note that every of our processes (ui, web, plugin, network) are just contains a simple main function that calls in to the same library.

I'm not saying that it's not possible or not a good idea but it's out of my scope.

I don't see the need ecore stuff here. In theory, our NetworkProcess should be identical to the GTK one. IMO we should call this one NetworkProcessMainSoup.cpp and use glib directly instead the WebCore mainloop abstraction.

Again, I think this is not Unix, but Soup.

I'm concerned that this change will break the build for other ports when using newer clang (which can detach unused member variables).

I agree. At some point I looked into doing this but never get around implementing it.

I also agree with Kenneth and Thiago. EFL port has used ecore_main_loop_glib_integrate() to support glib based library as libsoup. But, in this case, we can share this with GTK port. I don't use GMainLoop for EFL port yet directly, it looks there is no critical problem.

We can either share the generic RunLoop implementation everywhere, or not share at all. It is not practical to set up a special duplicate of the webkit2 dynamic library just to avoid the efl dependency here.

We could try a CMake trickery and build the RunLoop twice (the GTK and the EFL version) as a static library. The GTK version will only to be used here.

The core does use the RunLoop abstraction so you will not get more from the network process than a beautiful crash if you don't set it up properly.

Ok, I accept that you want to get rid of the glib-efl integration, but does not feel like it should be my task. I am supposing to remove the efl parts from here. This will in fact leave you with a broken network process, but since it is not used by default, it won't hurt anybody now. From this point you can chose how to solve the runloop issue, for example by making the gtk runloop built into the network process with some build system tricks.

Also I don't think we need NetworkProcessMainSoup.cpp, I think Qt can also use this file with a bit of ifdefs which is IMHO better than duplicating stuff.

This is handled in bug 109032.

D'oh! This time I was doing it in Xcode. Do you know how should I do it in a way Xcode accepts? Now I was 'duplicated' the file in Xcode, then removed the original, but it did no actually created the file at the new place on the file system just hacked the projcet file, so I actually made the move with git mv, than patched the file (at the new place). I did not find any option to actually move a file in Xcode. Or is a clean build necessary for Mac in this case?

This doesn't look right. Where is it copying the file to, and why?

Why is there no setter? if it won't ever be set to true yet, why not just return false; for now?

Ok, I will think how to slice it up further.

Not really, those silly messages are added by the commit-log-editor, but I can remove them if it makes reviewing easier.

Should I really leave there something that should be changed sooner or later anyway? Returning with the member here is harmless. I would rather keep it.

How would you do a debug-only check otherwise? That is what ASSERT_UNUSED has been introduced for.

[Balazs Kelemen]

Let's do this in smaller steps.

[Kwang Yul Seo]

I took over this work from Balazs because he is busy doing other works.

I've just managed to load a web page with NetworkProcess enabled in GTK port. I will upload patches soon after cleaning up the code.

I will work on Gtk port first and then move on to Efl. It would be trivial to support Efl because both ports share the same soup backend.

[Kwang Yul Seo]

Remvoed [EFL] from the subject because I am working on both Gtk and Efl ports.
