[webkit-dev] help identifying a workaround for a known bug

[bradley.morrison at nokia.com]

The "binary search" approach could possibly be automated by:

http://search.cpan.org/~coke/App-SVNBinarySearch-v0.1.0/svn_binary_searc
h

... of course assuming you have a test script that isolates the bug.

(note svn_binray search has a dependency on
http://search.cpan.org/~roode/Iterator-0.03/Iterator.pm)

There are two approaches:

1. "Reduce" the problem to the smallest amount of HTML that still
exhibits the problem, then post that information here.  There are many
open bugs on http://bugzilla.opendarwin.org/ that need reductions and
that haven't been fixed yet, so I doubt anyone has time to re-reduce
this issue.

2. Try a "binary search" of the nightly builds on
http://nightly.webkit.org/ to find out which nightly this bug was fixed
in.  (Basically, try the newest build and the oldest build.  The newest
build should have the issue fixed, while the oldest build should not.
Then choose a build half-way between these two by date, and try it.  If
it exibits the problem, choose a build half-way between that build and
the oldest build, else choose a build half-way between that build and
the newest build.  Continue until you've found where the fix occurred.)

If you find which nightly fixed the issue, you can isolate the WebKit
fix to the changes between that build and the previous nightly.  Then
you can use Subversion to look at logs between those dates or revision
numbers if they are SVN builds (these are just examples):

   svn log -v -r{2005-10-10}:{2005-10-11}
   svn log -v -r11935:11955

If the first nightly on that site had the problem fixed, then the fix
was sometime between the open source release of WebKit and that first
nightly.
