Bug 104969 – Merge MainResourceLoader into DocumentLoader

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Nate Chapin]

With bug 49246 landed, MainResourceLoader's purpose is no longer clearly defined, and is poorly named.  It isn't a ResourceLoader subclass (it implements the CachedRawResourceClient interface), and the organization of what DocumentLoader and MainResourceLoader each do is history rather than logical.  It's probably worth merging them into a single class.

This monster patch is my current thought for merging these 2 classes.  I'll split it up before asking for review, just posting to get EWS data.

Amazing.

I'm surprised we use a static here.  This is just a struct...

All reviewed patches have been landed.  Closing bug.

It appears that this patch broke Windows (Debug) Tests:
http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50526
http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50527

[Ryosuke Niwa]

To make sure this is a real regression, I've ran the tests at the same revision on two distinct machines (apple-windows-3 and apple-windows-4 respectively):
http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50528
http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50529

I'll also note that I've rebooted those bots prior to running the tests.

I'm sorry but I'm rolling out the patch for now as we're losing the entire test coverage on Windows Debug.

[Adam Barth]

Thanks.

It appears that this was a build corruption issue.

http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50532
is the run that contains the rollout and this looks better but still a bunch of tests have failed. I've triggered a clean build after this as http://build.webkit.org/builders/Apple%20Win%207%20Debug%20%28Tests%29/builds/50536 and this one appears to be running just fine.

Can we coordinate tomorrow to reland this patch so that we can trigger a clean build as needed tomorrow?  Alternatively, you don't do anything, I'll try to reland it tomorrow morning and start a clean build as needed.

If you want me around, it should probably wait until Thursday, as I'm OOO today and won't have IRC access until this afternoon.

Sorry about the unwanted noise.

I've relanded your patch in http://trac.webkit.org/changeset/146449 after cleaning WebKitBuild directories in apple-windows-1 and apple-windows-2.

[Eric Seidel (no email)]

I'm very excited to see this land!

Thanks for relanding this! I really appreciate it.
