Updating the Dreamwidth code on your Dreamhack
Shutting down apache
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:
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. First, if you are not somewhere in dw-free, get into that directory:
Then grab updates from the development branch of Dreamwidth's repository:
git fetch dreamwidth git checkout develop && git pull --ff-only dreamwidth develop:develop
You will also want to push the Dreamwidth repository changes to your fork on Github:
git push origin develop
If you have uncommitted changes, you'll get an error message and will need to use git stash.
For those using DW non-free
Repeat for dw-nonfree:
cd $LJHOME/ext/dw-nonfree git fetch dreamwidth git checkout develop && git pull --ff-only dreamwidth develop:develop git push origin develop
Update your database
Now that your code has been updated, update the database:
# 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
Remember that different branches might have different text strings you have added, and that you might need to update your database for different branches when you are working on them for those text strings to work. The same applies for any database changes made by different branches you are working on.
Compile the SCSS
You'll also want to compile any changes to the SCSS into CSS for dw-free:
cd $LJHOME compass compile # And dw-nonfree if you are using it: cd $LJHOME/ext/dw-nonfree compass compile
Restart the server
Now you can restart Apache:
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.)
Additional Information for Non-Dreamhack Users
This section is only for you if you're running your own installation.
Instead of using start-apache/stop-apache, which are Dreamhack-specific scripts, use these commands:
sudo /etc/init.d/apache2 start sudo /etc/init.d/apache2 stop
You'll also want to update packages on your system at some point. On Ubuntu, this would be done using:
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
You can, of course, use scripts to make it easier for you to do some of this.
There is an epic "omnibus" script by jeshyr available at http://dw-dev.dreamwidth.org/94822.html which incorporates all the individual scripts listed here and some other useful functions, and includes help information. It'll save you a heap of angst as a beginner!
Some simpler example scripts are given below.
dwu - Updating the repos
Put this code in a file called ~/bin/dwu and make it executable with chmod ugo+x ~/bin/dwu:
#!/bin/bash # make sure we are in the right directory; cd $LJHOME git fetch dreamwidth # pull changes from dreamwidth git checkout develop git pull --ff-only dreamwidth develop # push them to Github forks git push origin develop # restore our old position git checkout - # check to see if we have a dw-nonfree directory; if we do, update that too if [ -d "$LJHOME/ext/dw-nonfree" ]; then # change to dw-nonfree cd $LJHOME/ext/dw-nonfree git fetch dreamwidth # pull changes from dw-nonfree git checkout develop git pull --ff-only dreamwidth develop # push them to Github forks git push origin develop # restore our old position git checkout - fi
Now, when you type 'dwu', this script will update your dw-free and (if you have it) dw-nonfree repositories.
dwdb - Updating the database
Put this code in a file called ~/bin/dwdb and make it executable with chmod ugo+x ~/bin/dwdb:
#!/bin/bash $LJHOME/bin/upgrading/update-db.pl -r -p --innodb && $LJHOME/bin/upgrading/update-db.pl -r --cluster=all --innodb && $LJHOME/bin/upgrading/texttool.pl load
This will update the database when you type 'dwdb'.
comp - Recompiling the compass files
Put this code in a file called "'~/bin/comp'" and make it executable with "'chmod ugo+x ~/bin/comp'":
#!/bin/bash cd "$LJHOME" && compass compile && cd ext/dw-nonfree && compass compile
This will recompile the CSS files.
Cleaning up your directories
If you do any amount of work, you'll find that your directories get cluttered with .orig and .rej files everywhere. This script will clean those up:
git clean -f "*.rej" "*.orig"
You can run it from the command line, or put it in a file called ~/bin/tidy and make it executable with "chmod +x ~/bin/tidy". If you do that, you'll be able to just type "tidy" to clean house.
