Weekly report 9, LLVM-libc
Hi! This week I’ve pretty much finished the work on LLVM/Clang support for Crossdev and LLVM-libc ebuild(s). I have sent PRs for Crossdev and related ebuild changes here:
https://github.com/gentoo/crossdev/pull/10 https://github.com/gentoo/gentoo/pull/32136 This PR includes changes for compiler-rt which are always needed for Clang crossdev, regardless of libc. There are also changes to musl, kernel-2.eclass (for linux-headers), and a new eclass, cross.eclass.
Firefox Developer Experience: Firefox WebDriver Newsletter — 116
WebDriver is a remote control interface that enables introspection and control of user agents. As such it can help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).
This newsletter gives an overview of the work we’ve done as part of the Firefox 116 release cycle.
