Upgrading Drupal

Hi folks. I'm getting ready to embark on an upgarde from 4.6.3 to 4.6.5 and have a question for someone who's already installed 4.6.5.

There were a slew of problems in 4.6.3 related to INSERTs that attempted to pass NULLs to columns and which required modifications to some core modules (mostly to 'node' but I recall that 'comment' was affected by this as well) to rewrite the SQL so that the columns that were going to receive a NULL wouldn't be included in the generated SQL.

So, finally the questions:

After working with Drupal for about a month, I've made the commitment to implement it for my sites. Drupal is a terrific community effort. One of my struggles, however, is with how to maintain my Drupal code. I would appreciate guidance on addressing these challenges:

• How to know when Drupal core or a module has been updated?
• How to upgrade to new code while preserving the ability to rollback?

Has there ever been consideration of using some kind of install technology with Drupal and modules (e.g., rpm)?

Thanks.

I did the Fantastico upgrade from 4.5 to 4.6.5 and get the errors like the one that follows. What does it mean and how can I fix it?

user error: Table 'xokmax_drpl1.queue' doesn't exist
query: SELECT uid, vote FROM queue WHERE nid = 15 in /home/xokmax/public_html/community/includes/database.mysql.inc on line 66.

Thanks in advance,

David

I've just upgraded from php4.3 to php5.1.2 on my computer with apache2.047. The template.php file in my theme directory is now not being read correctly, and is causing garbage at the top of the page, before the page is displayed (its functions are not working). If I remove functions from the template.php, everything is fine.

The weird thing is, when I run the site on a webserver with php5, it seems to work fine. What could be wrong with my local install of php5? Everything seems to work fine locally if my template.php file is empty!

Ive upgraded mt php version to php5 using the xampp installation pack. Ever since then my old drupal site - 4.6 using bluemarin Xtemplate is displayed like this :
{head} {styles} {_BLOCK_.header.logo} {_BLOCK_.header.site_name}
{secondary_links}
{primary_links}
{_BLOCK_.header.search_box}
{_BLOCK_.header.blocks} {_BLOCK_.header.title} You are not authorized to access this page.

What to do ?
a new site, uses the 4.7 version is working beautiful

tnx.

Just finished an upgrade to 4.6.5. All is working well except the inline module. Here's the error message:

warning: filesize(): Stat failed for files/vc52boy.jpg (errno=2 - No such file or directory) in /home/shojo/public_html/test_site/modules/inline/inline.module on line 111.

and
