Title: Curl Abandons Rust-Based HTTP Backend After Four-Year Effort Despite 95% Completion
Introduction:
In a surprising turn of events, the widely-used command-line tool and library, curl, has announced the discontinuation of its four-year experiment to replace its existing HTTP backend with one written in Rust. This decision, revealed by curl’s founder Daniel Stenberg, comes despite the project reaching a reported 95% completion. The move highlights the complex challenges of integrating new technologies into established projects and raises questions about the future of language interoperability in critical software infrastructure.
Body:
The ambitious project, initiated in 2020 with funding from ISRG (the organization behind Let’s Encrypt), aimed to leverage Rust’s memory safety features to provide a more secure alternative to curl’s traditional C-based HTTP implementation. The plan was to use the Rust-based Hyper library as a drop-in replacement, allowing curl to benefit from the modern language’s strengths. As Stenberg wrote in an earlier blog post, this would allow “more code to run in a memory-safe language instead of relying on C entirely.”
The initial stages of the project were promising, with the Hyper backend passing the vast majority of curl’s test suites. However, as Stenberg recently explained, the final few percent proved insurmountable, leading to the project’s abandonment. The reasons for this setback are multifaceted, but two primary factors stand out:
-
Lack of User Demand: Despite the potential benefits, there appears to have been a lack of interest in the Hyper backend from both curl’s user base and the Hyper community itself. As Stenberg noted, “curl users don’t care about Hyper, and Hyper users don’t care about making it work with curl.” This lack of community engagement significantly hindered the project’s momentum.
-
Interoperability Challenges: The core of the problem lies in the architectural differences between the two languages. Libcurl, the engine behind curl, is written in C, while Hyper is a Rust library. Bridging this gap required a glue layer that demanded a rare combination of expertise. Developers needed to be proficient in both C and Rust, as well as possess a deep understanding of their respective architectures and network protocols. The lack of developers with this specific skill set proved to be a major roadblock. Stenberg had previously highlighted the absence of a C API in Hyper as a significant hurdle.
The project’s decline was foreshadowed earlier this year when Stenberg questioned the value of continuing the Hyper support, noting that development had stagnated with minimal contributions from the community. The Hyper backend had become, in his words, a burden.
Conclusion:
The decision to abandon the Hyper backend, despite significant progress, serves as a cautionary tale about the challenges of integrating new technologies into established software ecosystems. It highlights that technical feasibility is only one part of the equation; user adoption, community support, and the availability of specialized expertise are equally crucial for success. While the experiment ultimately failed to achieve its goal, it provides valuable lessons for future attempts to modernize legacy systems with new programming languages. The curl team will now focus on further optimizing its existing C-based implementation, while the broader software community will continue to grapple with the complexities of language interoperability. The question remains: how can we better bridge the gap between different programming language ecosystems to foster innovation and improve the security of critical software infrastructure?
