Error upgrading from 2.9.2 to 3.0.1

by

I have my wordpress install under svn. I was on version 2.9.2. These were the steps I took:

  • saved a copy of my current wordpress directory
  • cd into my top level wordpress directory
  • svn up (just to make sure that I have the latest of 2.9)
  • svn sw http://core.svn.wordpress.org/tags/3.0.1/ . (upgrade)
  • run wp-admin/upgrade.php
  • got this error “Fatal error: Call to undefined function is_multisite() in (my install directory)/wordpress/wp-includes/wp-db.php on line 505″

I looked around and some people think it’s a memory issue with PHP. So I tried the Memory Bump plugin and that didn’t work.

Any ideas?

Update:
Found this post. Downloaded the latest 3.0 tar and overwrote my wp-settings.php with the one in the download.

Get different errors now. “Fatal error: Cannot redeclare wp_load_image() (previously declared in /myinstalldir/wordpress/wp-includes/media.php:241) in /myinstalldir/wordpress/wp-admin/includes/image.php on line 168″

When I perform and svn status I see lots of ‘S’ flags (switched). Do I have to be concerned with that? wp-settings.php has that flag.

Update:
Here’s the output of the above svn sw from the root WordPress directory.

Update:
Output of svn st here. (Migrated the long listings to pastebin)

Update:
Output of svn info

I also used SVN before to update my wordpress installation. Up the working copied will get messed up very quickly with all the manual updates or files created by plugins.

I would always recommend to use the update functionality of wordpress if you only want to step from one tagged version to another one.

Although, I also use SVN for a local copy of wordpress to be able to quickly test my plugins in some old version real quick. I use Eclipse to switch from one to another tag and until now it worked out. But you’ll never know.

UPDATE:
I just tried to switch a clean checkout of 2.9.2 to 3.0.1 which looks like it is working, but I can only see the backend and not the frontend of the default single blog.

UPDATE:
What even the debug mode doesn’t tell me: As the default pre WP 3.0 theme is no longer available I just have to switch to the new “2010” theme. Now everything is working.

So switching does work, but as I said before, your working copy usually get’s messed up with a lot of files that might cause some problems updating your WP copy with SVN switch.
