MySQL tweaks.

[mattwoberts]

Firstly, I changed the method that ErrorStore uses to get the assembly path - as per the comments I made on pull request #49.

So - re: LogError in MySQL. I'm a bit stumped. MySQL.NET data connector doesn't support OUT params unless it's a sproc. So you can't fire an update that returns a GUID like you do.

I tried a few different things, and I've tweaked the code a little, here are the options:

• Use ON DUPLICATE KEY UPDATE to insert/update in one hit, but that wouldn't work with the minDate criteria, because it has to be based unique index on the table (so we'd have to include the rollup date as a column to make that work)
• Create a sproc. Would work, but feels wrong
• Wrap anything we're still concerned about in a transaction if that will help, which I'm not sure about.

bump

Hi. Just wondered if you'd had time to look at this. No biggy. We're using the mysql store just fine, it would be nice to see it pulled in though.

I thought I had merged this on your last bump - I really do apologize for the delay. It's now in master, and I appreciate the performance fixes. This was the outstanding issue that prevented a NuGet release, which I can now make for MySQL along with the core in 2.0.

Thanks!
