Toolchains and platforms are there to last, and yet my experience shows that they can be challenging for newcomers, and can still surprise experienced Bazelistas. Some time ago, a debug session led me to read the actual source code, and I ended up refactoring the messages dumped by `--toolchain_resolution_debug` in the hope to make them more intuitive and self-explanatory. This session will present the new message format and build upon its structure to explain the algorithm that drives platforms and toolchains selection. Attendees will build a clear mental model of that core part of Bazel. Additionally, the presentation will insist on the importance of crafting self-explanatory messages, along with the tradeoffs involved. Debugging toolchain issues is now easier than ever, and a little bit funny.
