Short – but unfortunatly to long for Twitter. With this little snippet you can get all commits from an svn working copy, repository or from a pure log:

svn log | ruby -e "puts STDIN.read.split(/\n/).select{|l| l =~ /^r\d+/}.map{|l| l.split('|')[1].strip}.uniq.sort"

Who has any guess why I did need this?

After DokuWiki has been released multiple times in the last few days because of security problems, I though it was a good time, to write a little script for automatically updating multiple instances. You can find the ruby script at http://gist.github.com/285219.

The ruby script basically automates the upgrade instructions from the DokuWiki main page. So the following actions are performed when executing the script:

1. Making a backup into /tmp/dokuwiki_backup_#{timestamp} of every installation.
2. Downloading the dokuwiki release (passed in as a parameter).
3. Extracting the files and copying everything to the installations (execept for the content of the /data directory).
4. Creating missing folders in the /data directory, making the owner www-data:www-data and chmodding them to 664.
5. Deleting files from a list of file from older revisions.

Within the script you need to specifiy this snipped for setting your DokuWiki installations:

# Definition of existing installation
INSTALLATIONS = [
  '/path/to/docu/wiki/installation1',
  '/path/to/docu/wiki/installation2'
].freeze

Then you can call for a new release as follows:

/path/to/script/upgrade_dokuwiki.rb http://www.splitbrain.org/_media/projects/dokuwiki/dokuwiki-2009-12-25c.tgz

If you want to improve the script, feel free to fork me on Gist.
