Just a little over a month ago we ushered a completely revamped GForge platform dubbed GForgeNext and today we are happy to announce the release of v18.1. Please remember we have changed our version numbering to reflect the year and the number of the release. Since this is the second release of 2018 this version coincides to v18.1 which should help customers quickly know how many versions behind they may be.
The biggest change in 18.1 is the addition of SVN commit hooks. This means that all customers using both Git and SVN can safely upgrade to this version. For our remaining customers still using CVS we will be adding that support in v19.0 due out the first quarter of next year.
We are still encouraging customers to reach out to us for a free consultation on the planning and upgrade process. If we don’t hear form you we will be reaching out to all our customers over the coming week.
This is part 3 in a series about the limitations of Github, and how they might be holding your team back from its full potential. If you want to go back and catch up, here’s Part 1 and Part 2.
Go ahead, I’ll wait right here.
Done? Okay, let’s move on.
Today’s discussion is about getting code merged. It’s one of the most fundamental things any software team has to do. If your team is anything like ours, it’s something you do many times every day. It might even be the kickoff for your Continuous Integration/Delivery process, as it is for us.
Getting things out quickly is important, but preventing outages from bad code is even more important. You probably want an easy way to review and even test code that doesn’t distract too much from the work you’re already doing.
Once again, Github has a wonderful system for promoting code from one repository or branch to another — the Pull Request (PR herein). In particular, the PR is great for open-source projects where people might want to contribute, even if they’re not members of the main project. The proposed contributions can be examined by the main project member(s) and be pulled in only if they’re helpful.
But like many other Github features, you may find the PR process to be mis-aligned to your needs, in a way that creates a little extra delay and a bit of confusion every time you use it.
Pull Requests 101
For those who haven’t tried one yet, a pull request (PR) is a special kind of task, asking someone to merge a set of changes (commits) from one place to another. In more general terms, you can think of it as promoting a chunk of work from one level to another — such as from a development branch to test and then to production, or from a hotfix branch to long-term-support.
Because it’s a request, it doesn’t involve any access to the project repository from any non-members. The project team can review the proposed changes and take them, ask for revisions, or ignore them. It’s a great model for open-source or otherwise loosely-coupled groups to share ideas and improvements.
Keep It In One Place
But that flexibility comes at a cost. Pull Requests are opened and managed separately from individual tasks, so you’re basically creating another task to review each task’s work. The open or closed status of each task can be independent of the status of the related PR. Additionally, there’s nothing stopping someone from submitting changes for multiple tasks in one PR, which can be confusing and difficult to review.
For software teams that aren’t open-source, this loose coupling actually creates more process, more overhead, and time thinking that could be spent doing instead.
Ask yourself — wouldn’t it be a lot easier to merge the code as an integral part of the task itself?
Singularity Of Purpose
Let’s start with an assumption — that in order to change your code, there should be a defined reason for doing so.
You’re writing code because something needs to be added or fixed. There’s a use case. A story. A bug. A feature. A customer who wants something. There’s a reason to change what you already have.
You probably also want to do two things with your tasks:
You want to create a plan ahead of time, for which things will be done, by whom, in what order.
You want to keep track of progress as things move along.
Once you start depending on tasks for planning and tracking, you can begin to improve your overall process, reducing the number of steps and the distance between idea and working code. As you do, separate PRs may start to lose their appeal. Asking developers to open a separate kind of ticket to get code merged is a hassle. Allowing them to put multiple bug fixes into one merge is asking for confusion and mistakes.
If you’re delivering code using a well-defined workflow, PRs can actually cause problems:
Audit trail — It’s difficult (or impossible) to know later which code changes went with which task.
Larger merges — the code review itself becomes much more complicated, since there are more commits, more changes files.
All or nothing — If you like the changes for task #1, and for task #2, but there are problems with the tests for task #3, the whole PR is sent back for rework. This means you’re likely sitting on changes for longer.
More conflicts — Pretty simple math: (Larger merges) + (All or nothing) = More conflicts.
Since there’s no way in Github to limit the content of a PR, there’s no good way to prevent this kind of behavior. Creating a PR for every single bug becomes a tedious time-sink that doesn’t add value to your day.
Now, you might argue that a Github PR can act as the task itself, and it does — but not really. PRs are only retrospective, meaning that you create one after (or while) doing the work. If you don’t create tasks before doing the work, then you’ll never have any way of planning or tracking progress.
For most teams, the overlap between tasks and PRs is additional work that doesn’t generate any value. What you really need is a way to automatically detect code changes, review those changes and then promote them to dev, test and production, all as part of the task.
This kind of integration means that you can go back to the task later, understand the intent of the change, and also see the code changes that went with it. Your task tracking becomes a source of institutional memory, so that people can move in and out of the team, or across different features without making old mistakes over and over again.
If your tools are preventing you from improving your process, maybe it’s time to improve your tools.
