The Lede
In a move that's likely to please BSD enthusiasts, the OpenBSD team has created a BSD-licensed implementation of rsync, a popular file-copying tool. Rsync, developed by the Samba team, has long been a staple in the Unix world, thanks to its ability to perform delta-based file transfers. However, its GNU General Public License (GPL) had limited its adoption in the BSD-licensed community. Enter openrsync, an implementation that's compatible with modern rsync but accepts only a subset of its command-line arguments.
Background & Context
Rsync has been a mainstay in the Unix world for over two decades, thanks to its efficiency and versatility. However, its GPL license had created a barrier for those who wanted to use it in their BSD-licensed projects. The OpenBSD team, known for their contributions to the BSD ecosystem, saw an opportunity to create a BSD-licensed implementation that would fill this gap. The result is openrsync, a tool that's designed to work seamlessly with modern rsync but with a more permissive license.
Deep Dive
According to the OpenBSD team, openrsync is designed to be a drop-in replacement for rsync, with a subset of its command-line arguments. This means that users can still enjoy the benefits of rsync's delta-based file transfers, but with a more permissive license. The team has also ensured that openrsync is compatible with modern rsync, which uses protocol 27. In terms of performance, the team claims that openrsync is on par with rsync, making it a reliable choice for file synchronization tasks. One notable aspect of openrsync is its use of a BSD-licensed license, which allows for greater flexibility in terms of modification and distribution. This is in line with the OpenBSD team's commitment to creating software that's truly free and open.
Expert Angle
According to Timothy Beyer, the maintainer of openrsync, the project is a response to the growing demand for a BSD-licensed implementation of rsync. 'We wanted to create a tool that would allow our users to enjoy the benefits of rsync, but without the restrictions of the GPL license,' he said. 'Openrsync is designed to be a drop-in replacement for rsync, with a subset of its command-line arguments. We believe that this will make it easier for users to adopt and contribute to the project.' When asked about the potential impact of openrsync, Beyer noted that the project has the potential to increase adoption in the BSD-licensed community, particularly in areas where GPL-licensed software is not suitable.
What Comes Next
As openrsync enters the scene, it's likely to have a significant impact on the BSD-licensed community. With its BSD-licensed license and compatibility with modern rsync, it's poised to become a popular choice for file synchronization tasks. In the near future, users can expect to see more packages and distributions incorporating openrsync. The OpenBSD team is also planning to continue developing and refining the project, with a focus on improving its performance and feature set. As the project gains traction, it will be interesting to see how it compares to rsync in terms of adoption and usage.
