Bug 151418 – Remove the non-NetworkProcess configurations

• Component: WebKit2
• Status: RESOLVED FIXED

[Alex Christensen]

NetworkProcess should be the default.  Supporting non-NetworkProcess code paths makes the code messy.

You can't remove this, it'll break nightlies. Just make these no-ops and move them to WKDeprecatedFunctions.cpp.

Ditto.

Pretty sure removing this is going to break the Mavericks build of Safari.

Ditto.

GTK build fixed in http://trac.webkit.org/changeset/192668
I'm looking into the API test failures now...

I haven't looked, but we probably have a test that makes sure webkit_web_context_get_process_model() after webkit_web_context_set_process_model() returns the process model that was set. Please don't worry about any GTK+ API tests you might have broken; we'll fix them.

A unit test failure probably means we would be changing the behaviour of our public API, we should ensure this change is backwards compatible. See my review on bug #151473.

It made the EFL bot early exit due to 50+ timeouts:
https://build.webkit.org/builders/EFL%20Linux%2064-bit%20Release%20WK2/builds/25632

It would be great if the maintainers could fix this issue before relanding 
this patch. Maybe EFL needs some refactoring similar to GTK port.

Patch with the GTK changes needed

This doesn't fix the unit tests timing out, but those tests don't work with using the network process for some reason. We can deal with them in a different bug.

I'm going to do this in pieces, starting with https://bugs.webkit.org/show_bug.cgi?id=151512 which shouldn't change the compiled output at all.

Ok, I've moved the GTK+ changes to its own bug then. It switches to use network process unconditionally in preparation for this change, so that when you fix this bug you only need to remove a few lines in the GTK+ port to make it build.

Thanks Carlos!

[Alex Christensen]

This is finished because all the dependent bugs are finished.  I've completely landed this in pieces.
