Upgrading Drupal

I was wondering if the settings.php file ever changes during upgrades, i rather like just copying over the sites folder from previous versions, quick and painless.

Hello Drupal Developers I am with heavy heart want to tell you all people that I have lost client after upgrading his site from 5.2 to 5.8.
I have done all the things which have been written in the Update.txt in drupal 5.8 module and after that I have tested the site on development and after taking permission from the client I have upgraded the live site to the 5.8 version, at that time it was working well but after some hours the site went down saying that

"MySQL: Too many connections"

Hi,

I am in the process of coding a module. I have seen that some modules alter base tables in drupal. I would like to know if I for example add a column to the users table, if I were to upgrade drupal, would this then reset the base tables to defaults?

reson I ask, I have groups that different users connect to, I need to add a column in the users table that will have an id of the group that this user belongs to.

Will the columns stay?

Thianks in advance,
Davin

I had a clean installation of Drupal 6.2 and I saw the Permissions page executing a jQuery to correct the table when roles where too much for the browser's width.
Now I have a clean installation of Drupal 6.3, same browsers (IE6-SP2 Windows, FireFox2.0.0.3 Windows & FireFox2.0.014 Linux) but the Permissions page doesn't execute any correction when the table is too wide.
am I missing something?

I'm testing both Drupal 5.8 and 6.3, both clean installation, no extra modules.
Is Drupal 6.3 so slow??
I think it has to be some wrong configuration on PHP, right?
Drupal 5.8 is performing very fast
Drupal 6.3 is performing really slow!
Comments?

I have a bit of a plug for Pro Drupal Development. Not only is it starting to help me learn Drupal, it's beginning to help me make sense of PHP! :) It's authors are too humble when they say it's not much of a help in learning PHP. Okay, you can't be a beginning programmer, but it doesn't take much "PHP skill" to be able to figure out what they're getting at.

That being said, Chapter 7 is giving me some difficulty. I've been able to add a "Content Type" programatically. Open up "Create Content" and sure enough in the sidebar you can add a joke type. However, what I haven't been able to figure out is how to make the link to add jokes available in the "middle block as well". Here's what the middle block usually has:

Create content
Choose the appropriate item from the list:

Forum topic
Image
Page
Poll
Story
Video

I took out the descriptions to make it less verbose but you get the picture. If my "joke" content type is in the sidebar under "Create Content" shouldn't it be updating the "middle screen" as well? I'm going to keep moving on with the book but if anyone has an idea for this let me know. In the meantime it's cool I can add content type to the left sidebar anyway.

The way I do this is upload a node module consisting of 3 files: You can browse the code quickly for an idea of what I'm doing.
