Is WordPress automatic install / upgrade compatible with a SVN deployment of WordPress? Oct 22 2009

Question: Is the built-in WordPress automatic install / upgrade process compatible with a SVN deployment of WordPress?

Short answer: Yes.

Ever since WordPress came out with the automatic upgrade functionality in 2.7 I’ve hesitated to use it since the majority of our client installs are deployed using Subversion (svn) and I wasn’t sure how it would react with the .svn directories.

Today I finally decided to figure it out, and found that the WordPress team coded their upgrading functions exactly correctly (as far as not overwriting or deleting .svn directories goes). In addition, their script correctly removes old and unneeded files that might be present.

First, check to make sure that our svn checkout is clean:

$ svn st

Next, we begin the automatic upgrade process.

Step 1: Click the WordPress 2.8.5 “Please update now.” link:
Step 2: Backup your files as suggested – http://codex.wordpress.org/WordPress_Backups
Step 3: Enter your FTP connection details and click the Proceed button
Step 4: Wait while the files are downloaded and unzipped. This can take a minute or two, so be patient.

Now we can check to see what files were changed:

$ svn st
M wp-app.php
M xmlrpc.php
M wp-includes/post-template.php
M wp-includes/version.php
M wp-includes/theme.php
M wp-includes/comment-template.php
M wp-includes/bookmark-template.php
M wp-includes/media.php
M wp-includes/formatting.php
M wp-includes/author-template.php

! wp-includes/images/audio.png
! wp-includes/images/zip.png

M wp-includes/capabilities.php
M wp-includes/classes.php
M wp-includes/category-template.php
? wp-content/plugins/hello.php
M wp-content/plugins/akismet/akismet.php
M wp-content/plugins/akismet/readme.txt
M wp-trackback.php
M readme.html
M wp-admin/includes/post.php
M wp-admin/includes/update-core.php
M wp-admin/post.php
! wp-admin/js/forms.js
! wp-admin/js/upload.js
M wp-admin/edit-attachment-rows.php
! wp-admin/import/btt.php
! wp-admin/import/jkw.php
M wp-admin/import/wordpress.php
! wp-admin/edit-form.php
! wp-admin/link-import.php
! wp-admin/images/media-button-gallery.gif
! wp-admin/images/tail.gif
! wp-admin/images/gear.png
! wp-admin/images/comment-stalk-classic.gif
! wp-admin/images/media-buttons.gif
! wp-admin/images/comment-stalk-rtl.gif
! wp-admin/images/tab.png
! wp-admin/images/comment-stalk-fresh.gif
! wp-admin/images/comment-pill.gif
! wp-admin/css/press-this-ie-rtl.css
! wp-admin/css/press-this-ie.css
! wp-admin/css/upload-rtl.css
M wp-admin/install.php
M wp-admin/page.php

Notice that some old files have been removed and others have been modified. (See http://codex.wordpress.org/Files_Automatically_Replaced_by_Core_Upgrade for details on all the old files that the automatic upgrader removes).

Next we schedule old files to be removed from svn:

$ svn st | grep ! | sed 's/! *//' | xargs svn rm;

Next we commit the modified files and the removed files:

$ svn ci -m "Upgrading to the latest version of WordPress 2.8.5"

That’s it. The WordPress automatic upgrade process does not interfere with .svn directories, and is therefore compatible with maintaining a deploy from Subversion workflow.

Obama wins 2009 Nobel Peace Prize – Congratulations! Oct 9 2009

Congratulations to President Barack Obama on winning the 2009 Nobel Peace Prize!

Obama wins Nobel Peace Prize

2009 Nobel Peace Prize press release:

The Nobel Peace Prize for 2009

The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2009 is to be awarded to President Barack Obama for his extraordinary efforts to strengthen international diplomacy and cooperation between peoples. The Committee has attached special importance to Obama’s vision of and work for a world without nuclear weapons.

Obama has as President created a new climate in international politics. Multilateral diplomacy has regained a central position, with emphasis on the role that the United Nations and other international institutions can play. Dialogue and negotiations are preferred as instruments for resolving even the most difficult international conflicts. The vision of a world free from nuclear arms has powerfully stimulated disarmament and arms control negotiations. Thanks to Obama’s initiative, the USA is now playing a more constructive role in meeting the great climatic challenges the world is confronting. Democracy and human rights are to be strengthened.

Only very rarely has a person to the same extent as Obama captured the world’s attention and given its people hope for a better future. His diplomacy is founded in the concept that those who are to lead the world must do so on the basis of values and attitudes that are shared by the majority of the world’s population.

For 108 years, the Norwegian Nobel Committee has sought to stimulate precisely that international policy and those attitudes for which Obama is now the world’s leading spokesman. The Committee endorses Obama’s appeal that “Now is the time for all of us to take our share of responsibility for a global response to global challenges.”

How to disallow browsing of .svn directories on your server Oct 6 2009

If you deploy projects live out of Subversion repositories to public web servers, here’s a good tip for denying access to the .svn directories to keep people from snooping around your files.

Edit your global Apache config file (httpd.conf) or .htaccess file to include the following directive:


# Disallow any .svn directory browsing
<directory ~ "\.svn">
Order allow,deny
Deny from all
</directory>

This will tell apache to not serve up any directories that are called .svn.
