bazel packages: add --record_rule_instantiation_callstack flag This flag (default: false) causes each rule to record the Starlark call stack at the moment of its instantiation. The stacks are displayed by blaze query --output=build. Example output: # /workspace/x/BUILD:2:1 cc_library( name = "a", ... ) # Instantiation stack: # /workspace/x/inc.bzl:4:3 called from g # /workspace/x/inc.bzl:2:3 called from f # /workspace/x/BUILD:2:1 called from <toplevel> By combining two optimizations, prefix sharing using a linked tree, and element compression using packed integers, this feature imposes an additional retained heap space cost of only 1.5% for deps(//X) where X is Google's web server.

{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.
One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.
Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.
Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
