RE: [Rainbowportal-devel] help

[Hongwei S. <hs...@oc...>]

Hello, Rainbow management,

I just developed a new functionality for HtmlDocument module to allow
editor or approver to compare the staging content with the production
content while working in workflow mode. If you think this functionality
is useful, please give me check-in permission to submit the code.

For you to evaluate it, I enclosed all the necessary files needed to
test the functionality. Among them:

1.  Rainbow.MergeEngine.dll, inside this class library, I first parse
the html strings into English words collection with html tags retained
but not compared, and then implement the algorithm proposed by Eugene W.
Myers (http://www.si.xmailserver.org/diff2.pdf it is also the algorithm
of Unix Diff) to compare the two words collections word-wisely (not
character wise). I plan to put the class library project under the
Extension repository. For testing, just save the enclosed dll file to
Rainbow/bin directory. Since I need a little bit more time to do
clean-up, the source code is not enclosed at this time.

2. PortalModuleControl.cs. Implementing the compare functionality
doesn't need to modify this file; however, there are two bugs in the
file that are triggered by my code. I fixed them and please read the
comment inside the code for details. For your convenience, the modified
locations are:
    a) Started from line 680 inside OnLoad=20
    b) Started from line 2933 inside protected void
RevertToProductionContent (object sender, EventArgs e)

3. HtmlModule.ascx.cs the functionality is implemented here.
Modification is inside the region "support for version comparison" and
at line 268 to turn on ViewState

4. Put the icon files in the themes/icon directory.

Note: All the files and test are based on Rainbow 15 Release, not on the
development version on CVS or SVN!

If you have any question, I can be reached by Hon...@gm...
during the weekend.

My sincere thanks to Matt Cowan, he pushed this work and did lots of
testing.
