           Summary: webkit-patch apply-attachment is very slow for big
                    patches
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ossy at webkit.org


I ran into this problem, because Qt EWS was very very slow today.
And the slowness was caused by big patches in https://bugs.webkit.org/show_bug.cgi?id=73643

I measured a little bit and found that apply-attachment is absolutely non effective now.

apply-attachment: 640 sec
($ Tools/Scripts/webkit-patch apply-attachment 120013)
 - Fetching: https://bugs.webkit.org/attachment.cgi?id=120013&action=edit : 100 sec
 - Fetching: https://bugs.webkit.org/show_bug.cgi?id=73643&ctype=xml : 420 sec
 - Processing patch 120013 from bug 73643 : 120 sec

my simple method: 85 sec
($ wget https://bugs.webkit.org/attachment.cgi?id=120013
 $ Tools/Scripts/svn-apply attachment.cgi?id=120013)
 - wget: 60 sec
 - svn-apply: 25 sec

It would be great if we can make webkit-patch apply-attachment faster for huge patches to make EWS bots faster.
