Обсуждение: Fw: PATCH (Re: Startup message issues)
Sorry. Again forgot to copy the list. (I'll get the hang of this eventually...). Here's what I mistakenly sent only to Kris, but meant to send to the list.

I'm not entirely confident that it's correct at this point. All the unit tests pass, but I'm still thinking about when I said the encoding field to UNICODE, and learning a lot more about the source as time goes on. I have just grabbed a version of the driver from CVS. I have a bit of a conflict here because I'm being paid to get stuff working under 7.4.1 for our production application; but if there's not a huge amount of effort involved, I'll try to submit patches for CVS instead. (By the way, where should I send JDBC driver patches in the future that I intend to be committed. I've realized just now that I'm the only person sending them here.) -- www.designacourse.com The Easiest Way to Train Anyone... Anywhere.

I read it, did some testing, and actually modified it slightly. You had a comment saying V2 when you meant V3 protocol. In StartupPacket I put the user and database variables into the params Hashtable. (I'm not convinced this is much better, but I was playing with this idea and thats how things ended up when I was ready to commit.) My only concern about the code is that String.getBytes is called in StartupPacket without specifying an encoding. I think this is potentially a problem depending on the user's encoding and if the values for username and database name. The code has been this way since it was originally written, so that's no reason not to commit your patch. > I have just grabbed a version of the driver from CVS.

Working for a 7.4.1 database or working for the 7.4.1 jar file? As you have noticed the driver has a bunch of backwards compatibility stuff, so you know the cvs driver will happing run against older versions of the database. > (By the way, where should I send JDBC driver patches in the future that I > intend to be committed.

Since the changes I'm planning on making are fairly major, I suppose it's senseless to apply normal logic about not using development code for a production application. So I'm now working with CVS and will plan to deploy from there. -- www.designacourse.com The Easiest Way to Train Anyone... Anywhere.
