Lightning Talks
summary
Nine five-minute updates cover tools, migrations, and proposals: buildifier/builder formats and programmatically edits BUILD files; a Skylark linter flags missing docs, shadowed builtins, and uninitialized vars; Gazelle generates and merges Go rules including platform-specific select logic; platforms/constraint rules land for precise toolchain selection; an android_local_test rule runs Robolectric with Bazel-style resource processing and incrementality; a browser consumer of the Build Event Protocol demos gRPC streaming; Envoy’s migration takes ~2 months, ~100 commits and 24k LOC churn with C++ dependency and coverage pain points; PayPal cuts full builds from ~30/45 minutes to <5; proposals add configurable rule keys and limited dynamic subgraphs for hard-to-model compilers.
