Updating your code

VERY IMPORTANT: If you have custom changes that you have not committed or patched out, you want to do that first! If you follow these steps without doing so, you will likely muck things up.

It is best to shut your Apache instance down before doing the update process, to make sure that everything, especially scripts in cgi-bin/ are reloaded properly:

sudo /etc/init.d/apache2 stop

Okay. Let's say you've been running your Dreamwidth install and you want to pull down the latest and greatest in fixes. This is pretty easy.

cd $LJHOME
bin/cvsreport.pl -update
# only sync changes from the CVS to the live code
bin/cvsreport.pl -sync -cvsonly
bin/cvsreport.pl -sync -cvsonly

Yes, you do it twice. If the multicvs.conf file changed, then the first one pulls that file in, and the second one will notice whatever changed according to that file. 99% of the time once is enough, but every once in a while... so it's a good habit to have.

# order of commands is important
$LJHOME/bin/upgrading/update-db.pl -r -p --innodb
$LJHOME/bin/upgrading/update-db.pl -r --cluster=all --innodb
$LJHOME/bin/upgrading/texttool.pl load

Now you can restart Apache:

sudo /etc/init.d/apache2 start

Of course, in a production environment, this whole process is not too recommended as you never know what kind of code you're going to get. But for the most part, it's fairly straightforward. (And if you're doing development, this is generally safe.)

Updating your system

On Ubuntu, you can update the packages on your system with:

apt-get update
apt-get upgrade

Or, if you want an easy command to run on your dw account in one swoop:

sudo apt-get update && sudo apt-get upgrade
