Note that some developers recommend deployment pipelines package the source code to deploy it and never have a production environment touch a source control system directly.

However, for small scale deployments it's often easiest to pull from source code when you're getting started instead of figuring out how to wrap the Python code in a system installation package. Numerous source control systems have been created over the past several decades. In the past, proprietary source control software offered features tailored to large development teams and specific project workflows. However, open source systems are now used for version control on the largest and most complicated software projects in existence.
There's no reason why your project should use anything other than an open source version control system in today's Python development world. The two primary choices are:. Mercurial is similar to Git, also a free and open source distributed version control system. Subversion is a centralized system where developers must check files in and out of the hosted repository to minimize merge conflicts. Git and Mercurial can be downloaded and run on your own server. However, it's easy and cheap to get started with a hosted version control service.
You can transition away from the service at a later time by moving your repositories if your needs change. A couple of recommended hosted version control services are:. GitLab has both a self-hosted version of its open source software as well as their hosted version with pricing for businesses that need additional hosting support. GitHub is a software-as-a-service platform that provides a user interface, tools and backup for developers to use with their Git repositories. BitBucket is Atlassian 's software-as-a-service tool that with a user interface, comparison tools and backup for Git projects.
There are many features in BitBucket focused on making it easier for groups of developers to work on projects together.
BitBucket also has private repositories for up to five users. Users pay for hosting private repositories with more than five users. Version control best practices is a good write up of how to work with version control systems.
Let’s start OSS development with Subversion (SVN)
The post is part of an ongoing deployment guide written by the folks at Rainforest. This lighthearted guide to the ten astonishments in version control history is a fun way to learn how systems developed over the past several decades. A visual guide to version control is a detailed article with real-life examples for why version control is necessary in software development. An introduction to version control shows the basic concepts behind version control systems.
What Is Version Control? Version control before Git with CVS goes into the history of version control systems and defines three generations, of which CVS and SVN were part of the second generation while Git and Mercurial are third-generation version control systems. About version control reviews the basics of distributed version control systems.
Why not Git? Monorepo versus multirepo version control strategies are a weirdly contentious topic in software development, likely because once a policy is set for an organization it is exceptionally difficult to change your approach. The following resources give more insight into the debate on how to structure your repositories.
Monorepo, Manyrepo, Metarepo is an awesome guide to varying ways of structuring your source repositories that contain more than one project. The guide covers advantages and disadvantages of common approaches used in both small and large organizations. Repo Style Wars: Mono vs Multi goes into the implications of using one side or the other and why it is unlikely you can create a combination solution that will give you the advantages of both without the disadvantages.
Why Google Stores Billions of Lines of Code in a Single Repository covers the history and background of Google's source control monorepo, which is one of if not the largest monorepo for an organization in the world. Advantages of monorepos goes into the advantages of using a monorepo and does not discuss the downsides but admits there are many so the decision is not clear-cut on using either strategy.
Monorepos and the Fallacy of Scale argues that having all of an organization's code in a single repository encourages code sharing. The author considers the concerns often raised about tight coupling between components in a monorepo code base but says that the advantages outweigh the disadvantages overall.
Git is the most widely-used source control system currently in use. Its distributed design eliminates the need to check files in and out of a centralized repository, which is a problem when using Subversion without a network connection. There is a full page on Git with further details and resources. Apache Subversion source code , often just called "Subversion" or "SVN", is a source control system implementation.
Synchronizing Local Files with a Repository
How to use Subversion SVN lays out the basic concepts and provides the first few steps for getting started tracking files. Pick a version control system. Git is recommended because on the web there are a significant number of tutorials to help both new and advanced users.
Learn basic use cases for version control such as committing changes, rolling back to earlier file versions and searching for when lines of code were modified during development history. Local repositories are exact copies of the central repository complete with the entire history of changes. Then you work on your local repository exactly as you would in SVN by creating new branches, tags, etc. Teams also opt for Git is open source and cross-platform, so support is available for all platforms, multiple sets of technologies, languages, and frameworks. There is one con teams find frustrating: the ever-growing complexing of history logs.
Because developers take extra steps when merging, history logs of each issue can become dense and difficult to decipher. This can potentially make analyzing your system harder.

Git vs. SVN: Which version control system is right for you?
Eclipse Subversive - Subversion (SVN) Team Provider | The Eclipse Foundation
Backlog in Development. SVN version control systems With all version control systems, project files sit on a server where you push your files to when you have completed your work on your local machine. Work is comprised of three parts: Trunk: The trunk is the hub of your current, stable code and product. It only includes tested, unbroken code. Branches: Here is where you house new code and features.
Using a copy of the trunk code, team members conduct research and development in the branch. Tags: Consider tags a duplicate of a branch at a given point in time. Marking your code with tags make it easy to review and, if necessary, revert your code. Git While centralized systems were the version control system of choice for nearly a decade, Git has surpassed them in recent years. Source Unlike SVN, Git utilizes multiple repositories: a central repository and a series of local repositories.
Because you commit to the central repository more often in SVN, network traffic slows everyone down. No more single point of failure. With SVN, if the central repository goes down or some code breaks the build then no other developers can commit their code until the repository is fixed. Developers can continue to commit code locally until the central repository has been fixed, and then they can push their changes. Unlike SVN, Git can work offline, allowing your team to continue working without losing features if they lose connection.
