Git offers simple and computationally inexpensive branching, which opens up the door to a variety of cool workflows. Putting aside all the bells and whistles, fundamentally an SCM tool is about collaboration: letting a team of developers work on a shared set of software files. That adds up to a lot of free lunches for hard-working hackers. Bitbucket would cost $600 per year compared to tens of thousands of dollars for Perforce. Bitbucket Server, which offers technical support and on premise installation, is a fraction of the cost of Perforce. Git by itself is open source and completely free. For larger teams, it can also require fairly expensive hardware for that big central server. Perforce, although it no longer publishes pricing, is known to be in the range of several hundred dollars per user for purchase and a percentage of that for annual renewals. Commands like viewing history ( p4 changes), creating a tag ( p4 label or p4 tag), making a branch ( p4 integ), or even making a file writable in your workspace ( p4 edit) require write access to the server – which is an obvious bottleneck when thousands of users are accessing that server. And that single central server becomes a bottleneck as teams and projects get bigger. Perforce, for the most part, requires a connection to the server in order to even see the history of changes. This makes the initial clone of the repository slower (unless you are using Smart Mirroring), but subsequent operations such as commit, blame, diff, merge, and log dramatically faster. Git is distributed: every developer has the full history of their code repository locally. Git is now the top SCM tool for software developers. Indeed, as ClearCase slowly fades away and Subversion stagnates, a few years ago Perforce seemed ripe for wider adoption.įast-forward to the present. And that’s the recipe for a successful commercial SCM product. It’s not as powerful as ClearCase, but it’s relatively fast and gets the job done. ![]() It isn’t free, but it’s much cheaper than ClearCase. ![]() ClearCase is incredibly expensive but powerful: it can handle real merges (up to a 64-way merge!), global development teams, and software projects with multiple modules. CVS is free and, feature-wise, worth every penny. Your two options for SCM are CVS and ClearCase. Why is that? In order to understand this lingering appeal, we’ll have to review some of the reasons why Git surpassed Perforce and other centralized SCM systems for general development, and see why the game development industry has been slower to switch. Yet Perforce, a commercial centralized SCM system, still resonates with game developers and other subsets of software developers. Today it is popular among professional teams of all scales, from indie developers to large enterprises, as well as critical open source projects such as Android and the Linux kernel. Interest in Git has grown steadily since its initial release in 2005. Git is the leading SCM solution for software developers.
