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:
If you have any uncommitted changes in your current branch (use git status to see), you can stash them to do this:
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
Note: if you are working on uncommitted changes in a branch, any automerge will be canceled. Example:
mw@memewidth:~/dw/src/jbackup$ git pull dreamwidth develop:develop remote: Counting objects: 180, done. remote: Compressing objects: 100% (54/54), done. remote: Total 116 (delta 90), reused 88 (delta 62) Receiving objects: 100% (116/116), 36.23 KiB, done. Resolving deltas: 100% (90/90), completed with 41 local objects. From https://github.com/dreamwidth/dw-free 53294c1..19b8e73 develop -> develop error: Your local changes to 'src/jbackup/jbackup.pl' would be overwritten by merge. Aborting. Please, commit your changes or stash them before you can merge.
After this, you can checkout the branch you were on previously and pop any work you stashed:
git checkout YOURBRANCH git stash pop
We will get into merging in changes in the following section.
Pulling changes from Dreamwidth's develop branch your branch(es)
You should be doing your development in branches separate from the main Dreamwidth branches. You can check what branches you currently have in your repository with the command:
The current branch will have an asterisk next to it. Here is an example:
email@example.com:~/dw$ git branch develop * feature/Mobile master
You can check to see if you have unsaved changes on your currently checked out branch with:
To temporarily save these changes while you make your updates, use:
To have your branch pick up the changes made on Dreamwidth's development branch:
git pull --rebase --ff-only dreamwidth develop
And if you have saved changes using stash, you can recover them with:
git stash pop
You can change branches with git checkout BRANCH, example:
git checkout feature/Mobile
For those using DW non-free
Repeat for dw-nonfree:
cd $LJHOME/ext/dw-nonfree git checkout develop && git pull --ff-only dreamwidth develop:develop git push origin develop
If you have any branches on dw-nonfree, they will also need to be merged with the development branch of dw-nonfree as described in the above section:
git merge 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 both dw-free and dw-nonfree:
cd $LJHOME compass compile 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 $LJHOME git fetch dreamwidth # save our position OLDDWPOS=$(git rev-parse --abbrev-ref HEAD) if [[ "$OLDDWPOS" == "HEAD" ]]; then OLDDWPOS=$(git rev-parse HEAD) fi # 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 "$OLDDWPOS" # check to see if we have a dw-nonfree directory; if we do, update that too if [ -d "$LJHOME/ext/dw-nonfree" ]; then # change to dw-nonfree cd $LJHOME/ext/dw-nonfree git fetch dreamwidth # save our position OLDDWNFPOS=$(git rev-parse --abbrev-ref HEAD) if [[ "$OLDDWNFPOS" == "HEAD" ]]; then OLDDWNFPOS=$(git rev-parse HEAD) fi # 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 "$OLDDWNFPOS" 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'.
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.
