Both ToT WebKit and Chromium appears to hang when I try to open: https://bugs.webkit.org/attachment.cgi?id=125284&action=review It's only 2.14MB! WebKit shouldn't be hanging on this page.
Note the patch is for https://bugs.webkit.org/show_bug.cgi?id=77504.
on my blackerry device it rebooted the phone, on iphone it killed the browser...
Just note that this bug is about fixing WebKit to load it fast, not about "fixing" our Bugzilla.
@ap - Now that we have moved to GitHub for review, do you think it is OK to keep it open. Also devices has evolved a lot and also I am not able to open link from Comment 0 but this also work (another 1.4 MB one): https://bugs.webkit.org/attachment.cgi?id=125233&action=review It takes time to load in Safari & Chrome but should we keep it as open for performance profiling?
There were a lot of line layout performance improvements lately, and indeed, large patches appears to work well now. At this point, patches in Bugzilla remain a supported way to contribute to WebKit.
