Re: Subversion > Bugzilla integration through MySQL

Thanks Larry!!

I think that deserves a little DOH!! I threw the change in real quick
before I did a commit just now, and I got my bug update. So now I
consider this as a new, working integration script.

I am in the process of also setting up a repository viewer from which I
can then create a URL inside of the Bugzilla note to create a link back
to that particular file in the repository at that noted revision
number. I have started building that code into the script as well, and
will have an almost completely seamless two-way integration by the end
of next week (in the hour here or there that I have to put towards it).

Once I get this done, is there somewhere I can upload the script to
share?? I don't want to have to keep emailing it out to everyone who
asks. I'd rather throw it up for others to improve upon since I know it
will have some flaws.

Regards,
Frank
