WordPress Upgrade Script

Even though the WordPress upgrade is easy, it’s troublesome. So I wrote a script to do it for me. Yep. There’s lots of these out there. And a lot of hosts (including mine) have a one-click install/update thing. But for some reason, I decided to write my own script. In python. Got to use a bunch of modules I’ve never used before, so it was a good experience.

How to Use

Run this script from the directory that contains your wordpress directory, on your server. I think it requires Python version 2.3. I ran it with 2.3.5. Use python -V to check the version. There’s two methods to run it.

With Prompts

1: Be prompted to push the Enter key to continue at each major step. Nice for the first time.

python wp-upgrade.py

Example output:

python ../src/wp-upgrade/wp-upgrade.py 
Current WordPress Version: '2.5'
Newest WordPress Version:  2.6.1

After that, you're All Done!
Go re-enable all your plugins and make sure everything works.
If you need to, you can always roll back by renaming the backup to 'wordpress'.
 
 
			[[Press Enter to Continue]]

Without Prompts

2. Do everything without a prompt. Do this by passing the -q option. The -q is for quiet and prints the same messages, but doesn’t wait for the user to press Enter. Blasts through the whole upgrade in one step.

python wp-upgrade.py -q

Example output would be the same as the above, minus the “[[Push Enter to Continue]]” bits.

What’s it do?

If you look at the above output, which is from my own site, you can see what it does. It will compare your installed wordpress version and to the latest available from http://www.wordpress.org. If your version is older, it will download the new one, extract it, perform the appropriate steps to update the old one. Note that the default themes and plugins will be overwritten, which is fine as long as you didn’t customize them. After it’s done, your wordpress directory should be up-to-date (you just have to visit the upgrade page), and you should have a wordpress 2.5 backup containing the directory as it was before running the script (and 2.5 would be the appropriate version). Also, there’s two variables you will (probably) want to customize: wpsite and wpdir. That’s it, basically.

  1. Shirley Says:

    Does this deactivate the active plugins before the upgrade? If not, the database can be corrupted by the upgrade. The scripts says re-enable ALL plugins in the end, which is kinda strange.

  2. Steve Says:

    It doesn’t touch any database stuff, it just works on the directories. So no, it doesn’t deactivate the plugins before running… That’s the user’s responsibility! 😛 I guess I could add a warning message…

    What I meant by “all” is all the plugins the user had previously disabled and wants enabled again.
