Remove Deleted Git Branches

Due to using to Github flow quite heavily, I end up with a lot of rogue branches locally that I'm always forgetting to cleanup. The snippet below is a quick one-liner I have aliased to cleanup-branches which saves me some time and keeps me out of branch spaghetti when autocompleting.



Awesome Tools I've Been Using

I recently just passed my probation period and got hired full time at Performance Horizon which means I get to work on awesome technology with a great team for the foreseeable future! Over the last 3 months I've met really interesting people, attended conferences and meetups, worked on complex edge cases and compiled quite an inventory of tools I use in my daily work. This post is pretty much a summary of those tools and my opinion on why I think you should give them a try. I've included all the links to the mentioned projects at the bottom of this post.



Free Hosting with Github Pages

I've been meaning to try out Github Pages for quite a while, but never had a project that was suitable as nearly all of my work is built on a custom back end server. I also wanted to get a few old projects online to share the code so people can maybe do something cool with it.



Deploying Websites with Git

Are you still using FTP for website deployment? Don't. If you're like me, and think there isn't a better solution then look no further than Git deployment. This topic has interested me for a very long time, but I'd never found a way to do it efficiently with the least amount of overhead and set up complexity. Before now I was currently using a mixture of FTP and Rsync to manage uploads, but both of these had major drawbacks.


FTP

Where do I start with FTP? It's an outdated protocol which isn't very good for syncing changes, and unless you have some kind of automatic syncing software, it's a tedious manual job. Until Recently I was using this for nearly all of projects, and I'm quite embarrassed about it to be honest. As a developer who is always trying out new technology across the board and always up to date, there is just no excuse for still using FTP. The advantage FTP has is the transfer speed, but when you factor in how insecure, heavy and failure-prone it is, it is still the worst choice.


Rsync

Rsync is a beautiful way to sync updates to projects and websites. It's fast, only updates files which have changed and if you write a script it can be entirely automated. The main reason I use Rsync is for replicating changes through multiple servers and data centres. The script detects the files changes which need to be pushed, and updates them accordingly on a schedule, or when it detects the files have been changed in a similar way to how Dropbox works. The reason I don't use it for everything is I can't find a decent Windows solution and I still use Win7 quite a lot for development both at work and home.


Git

Now we're on to the powerful stuff you all came to see. What are the main advantages of Git Deployment then? First of all, for many of you guys, git will be your main source of version control and where you host your projects if you're working in a team. One of the largest examples of this would be Github, which I'm sure you've all heard of. Personally, I use my own custom built Git system on a VPS, mainly for customization, security and cost reduction due to the large amount of projects I manage. I will write a post on that later on, explaining how to host your own git repositories without any additional cost.

To start with, I am going to assume you have sufficient basic experience with the Linux command line. All of these commands are done through a remote server, and depend upon you have public keys set up. Go ahead and login to your server and create a folder where you will keep your repositories (e.g /var/www/git) and then create another folder specific to your first project (e.g /var/www/git/project1). Navigate into this directory and type the following commands, where $worktree is an absolute path to the folder where you keep your actual site files (e.g /var/www/html). The worktree part is important, or it won't deploy to the correct directory. Also, If you're curious why I'm doing it in a separate folder and modifying the worktree rather than the same directory as the site, is so that the .git folder is completely separate for backup purposes, and there are less files in the document root. It's especially useful when deploying on multiple servers. I deploy via git to a master server per cluster, then internally Rsync takes over and only syncs the files it needs to the internal cluster, thus saving overhead on deploying to 30 different machines.


$ git init
$ git config receive.denycurrentbranch ignore
$ git config core.worktree $worktree
$ sudo nano .git/hooks/post-receive
#!/bin/sh
env -i git checkout -f
echo "Deployed!"
$ sudo chmod +x .git/hooks/post-receive

Then on your local machine you will want to add another remote to your git repo.


$ git remote add live ssh://yourserver/var/www/git/project1

As I mentioned before, you will have to have already setup public keys for access to your server via SSH or else this method won't work. I've read through a lot of articles on deploying through git, and tried them all and this method was the best Hybrid I found. It doesn't require a bare repository, you can push/pull from it like a normal repo and it doesn't destroy and static files you may have in your document root on your server such as file uploads from users.

When you're ready, simply commit then push to it like a normal remote. I create a .bat or .sh file with the following content, for automatic deployment without having to do this every time.


$ git add .
$ git commit -am "Automatic Deployment"
$ git push live master

Another great use for this kind of deployment I've found it the ability to have seperate remotes pointing to different machines for testing purposes. If I'm not 100% sure that something will work live, I can send it to a sandbox machine first via a different remote, then once it works there, simply repeat the process with the live remote and within seconds the site is live.

If you have any questions or suggestions I'm happy to chat with anyone interested in this kind of deployment or similar.
