C interpreters underlie many of our most widely used language implementations -- but they're slow. Wouldn't it be great if we could turn them into JIT compiling VMs? This video shows what happens when we do just that to the normal Lua VM (first) and "yklua" (Lua w/JIT, second).

CTI - Making a decision for glibc. Previous message (by thread): [PATCH v2 3/3] nss: Missing checks in __nss_configure_lookup, __nss_database_get (bug 28940) Next message (by thread): CTI - Making a decision for glibc. Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] tl;dr The GNU Maintainers for the GNU C Library (glibc) plan to move core services to infrastructure hosted by the Core Toolchain Infrastructure (CTI) project. As maintainers for the project we do this to meet the present and future needs of glibc and the GNU Toolchain. We want secure, robust, and sustainable infrastructure, balanced against the needs of developers and the community to collaborate and innovate, with reliable funding to support the infrastructure in the long term. In 2019 leadership from the GNU Toolchain started down a path that led to the Core Toolchain Infrastructure project. The project aims to move toolchain infrastructure issues forward; to provide a sustainable path forward for secure and state of the art infrastructure. Post-pandemic, since 2022 the GNU Toolchain has continued to move forward the state of the current infrastructure by engaging the developers, the projects, and a wider set of sponsors that can support a sustainable path forward for the toolchain. Key achievements: 2022 - Started using infrastructure provided by CTI like BigBlueButton for meetings for the GNU Toolchain e.g. Weekly glibc patch queue review and Monthly Office hours in two timezones. 2023 - Service enumeration for GNU Toolchain projects (gcc, glibc, binutils, gdb). 2024 - Completed pricing and service contract negotiation for migration with LF IT. 2025 - Completed GNU Toolchain and glibc documents to define secure development requirements and the infrastructure needs. These steps were a necessary evolution and resulted in several critical milestones, e.g., service enumeration, secure development documents; which collectively paved the way for a sustainable path forward. While it was clear to the GNU Toolchain leadership that requirements were coming to improve the toolchain cyber-security posture, these requirements were not clear to all project developers. As part of receiving this feedback we have worked to document and define a secure development policy for glibc and at a higher level the GNU Toolchain. While Sourceware has started making some critical technical changes, the GNU Toolchain still faces serious, systemic concerns about securing a global, highly available service and building a sustainable, diverse sponsorship model. At the same time we are freeing up the GNU Toolchain developers and volunteers to focus on next-generation work, such as Sourceware’s post-commit CI and Forge-based workflows. The decision to leverage CTI and LF IT is the direct result of seeking a comprehensive, long-term solution to these exact challenges, expanding our sponsorship base and leveraging existing sponsors like the OpenSSF. The CTI TAC’s proposal to use Linux Foundation IT is rooted in the fact that they are an existing team in the industry that implements very similar functionality for the Linux kernel. The proposal directly benefits glibc developers. By partnering with a team that develops and understands FOSS tooling (b4, grokmirror and patatt) and large-scale kernel infrastructure. This partnership ensures our core infrastructure is secure and scalable. This sustainable path forward for glibc includes: * A global robust and secure mirrored git repository for public clones that supports robust CI/CD workflows for developers and downstream distributions. * A global robust and scalable email system leveraging existing production deployments and reputation i.e. subspace.kernel.org. * A continuous process of review for project requirements, FOSS usage, security policy, and cost. * A sustainable funding model for the infrastructure including a diverse collection of sponsors to support various infrastructure requirements now and in the future. While consensus for the move among GNU Maintainers for glibc is not unanimous, most of the maintainers endorse the move, and key developers have expressed their support in the upstream discussions. Additionally CTI has received a lot of feedback over the last 3 years as the project worked on infrastructure, and we include some of that feedback here and in our CTI FAQ [1] with comments. Some members of the community have expressed disappointment that funding would go to the Linux Foundation. Some members of the community have expressed concern that a board structure would allow corporate influence. Neither of these concerns are new and exist today with Red Hat and IBM, both being for-profit corporate entities. The GNU Toolchain leadership has a 30+ year history of successfully navigating the dynamics of working with sponsors and providing FOSS solutions, including meeting the GNU Ethical Repository hosting criteria. We invite all members of the glibc and GNU Toolchain community to join us in this important transition. Your insights, contributions, and feedback are essential to making CTI infrastructure a success that benefits everyone. Let's work together to build a more secure and sustainable future — reach out on libc-alpha@sourceware.org, participate in the weekly office hours, or propose ways to get involved. Let's collaborate to build a more resilient and sustainable infrastructure foundation for the GNU Toolchain. Action plan: * Weekly office hours for CTI to provide an open space for discussion of infrastructure improvements * Work with LF IT to update the CY24 statement of work and discuss with the glibc developers * Work towards migrating glibc git and mailing lists as first priority since these match our security priorities. Cheers, Carlos O’Donell GNU Maintainer for glibc Core Toolchain Infrastructure Project TAC member [1] https://cti.coretoolchain.dev/faq/index.html
