GitHub vs SVN (Subversion): What are the differences?
GitHub and SVN (Subversion) are two popular version control systems. Here are the key differences between GitHub and SVN:
Distributed vs Centralized: GitHub is a distributed version control system (DVCS), while SVN is a centralized version control system. In GitHub, each user has a complete copy of the repository, including its entire history, allowing for offline work and efficient collaboration. Changes can be committed locally and later pushed to the central repository. SVN, on the other hand, relies on a central repository where users commit their changes directly. This centralized approach may require constant network connectivity and can limit offline work and collaboration flexibility.
Branching and Merging: GitHub excels in its branching and merging capabilities. It provides lightweight and easy-to-use branches, allowing developers to work on different features or fixes simultaneously. Branches can be created, merged, and managed efficiently, enabling collaborative development and minimizing conflicts. SVN also supports branching and merging but with a more heavyweight approach. Creating branches in SVN involves copying the entire repository, which can be time-consuming and resource-intensive.
Collaboration and Community: GitHub is a popular platform for open-source collaboration, with a vibrant developer community. It fosters community contributions and provides social features. SVN is often used in traditional corporate environments, focusing on team-based development within the organization rather than community-driven collaboration.
Workflow and Tooling: GitHub supports continuous integration and deployment (CI/CD) through integrations with popular tools like Jenkins, Travis CI, and CircleCI. GitHub also provides extensive APIs and webhooks for custom integrations and automation. SVN, while it has some tooling and integrations available, typically relies on a separate build and deployment infrastructure outside of the version control system itself.
Open Source vs Proprietary: GitHub is a cloud-based service and is built around open-source principles. It hosts millions of open-source projects and offers free public repositories. GitHub also provides paid options for private repositories with additional features and storage. SVN, on the other hand, is an open-source centralized version control system that can be self-hosted or used with SVN hosting providers. It doesn't have the same cloud-based infrastructure and community-driven ecosystem as GitHub.
In summary, GitHub is a popular distributed version control system for open-source collaboration, offering features like pull requests and issue tracking. SVN is a centralized version control system commonly used in corporate environments with a more team-focused approach.
Do you review your Pull/Merge Request before assigning Reviewers?
If you work in a team opening a Pull Request (or Merge Request) looks appropriate. However, have you ever thought about opening a Pull/Merge Request when working by yourself? Here's a checklist of things you can review in your own:
- Pick the correct target branch
- Make Drafts explicit
- Name things properly
- Ask help for tools
- Remove the noise
- Fetch necessary data
- Understand Mergeability
- Pass the message
- Add screenshots
- Be found in the future
- Comment inline in your changes
Read the blog post for more detailed explanation for each item :D
What else do you review before asking for code review?
Using an inclusive language is crucial for fostering a diverse culture. Git has changed the naming conventions to be more language-inclusive, and so you should change. Our development tools, like GitHub and GitLab, already supports the change.
SourceLevel deals very nicely with repositories that changed the master branch to a more appropriate word. Besides, you can use the grep linter the look for exclusive terms contained in the source code.
As the inclusive language gap may happen in other aspects of our lives, have you already thought about them?
One of the magic tricks git performs is the ability to rewrite log history. You can do it in many ways, but git rebase -i
is the one I most use. With this command, It’s possible to switch commits order, remove a commit, squash two or more commits, or edit, for instance.
It’s particularly useful to run it before opening a pull request. It allows developers to “clean up” the mess and organize commits before submitting to review. If you follow the practice 3 and 4, then the list of commits should look very similar to a task list. It should reveal the rationale you had, telling the story of how you end up with that final code.
Out of most of the VCS solutions out there, we found Gitlab was the most feature complete with a free community edition. Their DevSecops offering is also a very robust solution. Gitlab CI/CD was quite easy to setup and the direct integration with your VCS + CI/CD is also a bonus. Out of the box integration with major cloud providers, alerting through instant messages etc. are all extremely convenient. We push our CI/CD updates to MS Teams.
Gitlab as A LOT of features that GitHub and Azure DevOps are missing. Even if both GH and Azure are backed by Microsoft, GitLab being open source has a faster upgrade rate and the hosted by gitlab.com solution seems more appealing than anything else! Quick win: the UI is way better and the Pipeline is way easier to setup on GitLab!
At DeployPlace we use self-hosted GitLab, we have chosen GitLab as most of us are familiar with it. We are happy with all features GitLab provides, I can’t imagine our life without integrated GitLab CI. Another important feature for us is integrated code review tool, we use it every day, we use merge requests, code reviews, branching. To be honest, most of us have GitHub accounts as well, we like to contribute in open source, and we want to be a part of the tech community, but lack of solutions from GitHub in the area of CI doesn’t let us chose it for our projects.
