Various improvements to Python support in Bazel:

- Make it possible to select the Python2/Python3 binaries to be used on the command line. Ideally, we'd also support hermetic Python runtimes, but no one wants them at the moment, so let's not do speculative work.
- Make the Python stub script compatible with Python3.
- Use the Python3 binary for py_binaries that are built for it.

Bazel (Alpha)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
