Automating fixDAVsvn ¬

2009-11-17

I published my fixDAVsvn script seven months (and one day) ago to automate the process of fixing apache configuration files that have been manually modified to serve up Subversion repositories (per Nayan Hajratwala’s instructions) when they’re overwritten by Server Admin. This has made managing my apache install considerably easier, but upon rolling it out on a colleague’s server this afternoon I realized it was only ever a half solution. Sure, I had saved myself considerable time just by running fixDAVsvn, but others aren’t necessarily going to want to and there’s really no need. Time to add the second half.

So, how does one automate the process of running a command on a particular file whenever it’s modified? With launchd, of course! launchd drives some admins nuts, but I find it to be quite a boon and this happens to be exactly one of the cases it was designed for. So, I whipped up /Library/LaunchDaemons/com.makkintosshu.fixDAVsvn.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN http://www.apple.com/DTDs/PropertyList-1.0.dtd >
<plist version="1.0">
<dict>
	<key>Label</key>
	<string>com.makkintosshu.fixDAVsvn</string>
	<key>ProgramArguments</key>
	<array>
		<string>/usr/local/bin/fixDAVsvn</string>
		<string>/etc/apache2/sites/0001_any_80_svn.domain.tld.conf</string>
	</array>
	<key>WatchPaths</key>
	<array>
		<string>/etc/apache2/sites/0001_any_80_svn.domain.tld.conf</string>
	</array>
</dict>
</plist>

The full path to the config file to run fixDAVsvn on needs to exist in both the ProgramArguments & WatchPaths arrays in com.makkintosshu.fixDAVsvn.plist. That said, you can add as many config files to watch and fix as you like.

So, the complete solution¹ is to install fixDAVsvn and com.makkintosshu.fixDAVsvn.plist, then edit the latter to watch & fix your modified apache configuration files. I’ll likely package this all up with a script to build com.makkintosshu.fixDAVsvn.plist’s list of files automatically, but it may be another seven months.

¹ This solution has been tested on both Mac OS X 10.5 (Leopard) Server and Mac OS X 10.6 (Snow Leopard) Server.

Adium 1.4 Beta Adds Twitter Support ¬

2009-05-19

The beta process for Adium 1.4 has started and the new version includes built-in support for Twitter, as well as IRC and a “ridiculously long list of improvements.” It requires Mac OS X 10.5 Leopard and I have yet to test it.

I’m noting this due to the fact that my, now long-outdated, ‘Twitter & Adium Now Best Friends’ article has been getting lots of traffic as of late.

fixDAVsvn ¬

2009-03-07

Subversion, mod_dav, and mod_dav_svn are all pre-installed on Leopard Server, authentication via Open Directory is a piece of cake, and you can even mostly config & manage via Server Admin. Nayan Hajratwala has a good tutorial explaining the setup and the few lines you have to manually add to the apache config files, but there’s one problem: whenever you update any site using Server Admin, it replaces all occurrences of ‘DAV svn’ with ‘DAV Off’, completely defeating the purpose.

When I just had just a couple of Subversion repositories and wasn’t changing my apache configs very frequently it was fine to manually switch ‘DAV Off’ back to ‘DAV svn’ and restart apache, but recently I’ve exceeded my tolerance. So, this morning I whipped up the following bash script which accepts the names of config files that’ll need to be fixed, performs the substitution, and restarts apache:

#!/bin/bash

# 
# fixDAVsvn - Replace occurrences of 'DAV Off' in specified apache2 configs with
#             'DAV svn' and restart apache. This helps do some dirty work on Mac
#             OS X Server when using Server Admin to modify apache configs if
#             you use DAV svn anywhere.
# 
# v0.1   - 2009-03-07 - Morgan Aldridge <morgant@makkintosshu.com>
#                       Initial development.
# 

date=`date "+%Y-%m-%d-%H%M"`

function usage() {
	printf "Usage: fixDAVsvn file [...]\n"
}

if [ $# -gt 0 ]; then
	until [ -z "$1" ]; do
		src=$1
		dst=$src-$date.bak
		rsync -a $src $dst	# back up the original file
		cat $dst | sed 's/DAV Off/DAV svn/g' > $src	# replace 'DAV Off' w/'DAV svn'
		shift
	done

	/usr/sbin/apachectl restart	# reload the apache configs
else
	usage
fi

I’d suggest installing it into /usr/local/bin/.

Example usage:

sudo fixDAVsvn /etc/apache2/sites/0003_any_80_svn.domain.tld.conf

Let me know if you find this useful.

Update: I’ve since released a launchd job which automates the process of running fixDAVsvn when the apache config files are modified (esp. by Server Admin).

Subversion on Leopard Server ¬

2008-06-05

[H]ere is how I got my subversion repository up and running with the built in Apache 2 and OpenDirectory.

Very simple and straightforward instructions for setting up WebDAV access (with authentication) to your Subversion repositories under Leopard Server. Worked like a charm for me.

Unplanned Downtime; Tiger Server to Leopard Server Migration ¬

2008-06-05

I had planned the migration from Tiger Server to Leopard Server for this week, but hadn’t intended to do it today nor during daytime hours. Unfortunately, a DOS attack on UNNA prompted me to go ahead and upgrade so that I could work on alleviating that issue.

About 13 hours later (including a few hours to walk the dog and eat dinner), my Mac mini server is back up and now running Mac OS X 10.5.3 Server. I’ve run into some issues with 10.5.2 Server and earlier at my day job, but this revision seems to be quite a bit better. The migration went very smoothly and some service configurations were just drop-in replacements.

I have yet to start migrating backup scripts and some special services requiring custom Startup Items which will need to be re-written as launchd jobs. Also, UNNA has many PHP 4 to PHP 5 growing pains for me to work through as I’ve been working on migrating it to the Textpattern CMS as of late. I may have to refocus a bit of that effort over the next few days to get it cleaned up again.

I’ll try to describe the funky setup I’ve got in further posts, but here’s to hoping that Mac OS X 10.5.3 Server really does embody many more improvements and will give me few headaches going forward.
