Improve performance of BuildOptions#diff. Improvements come from:

1. Avoiding calls to BuildOptions#equals. When initializing the fingerprint and hash code, it does much of the same map iteration work that, if #equals returns false, is going to be done anyway in #diff. I haven't encountered a case where #equals returns true, but I've kept some inexpensive checks there just in case.
2. Not calling FragmentOptions#equals for similar reasons - it does the same map construction/iteration work that is going to be done anyway right after. Future work could be to try to maximize the chances of reference-equal FragmentOptions instances - right now we clone them a lot when they aren't going to be mutated.
3. Not calling OptionsDefinition#getOptionName, which is somewhat expensive because it looks up an annotation field.
4. Not calling FragmentOptions#asMap. The OptionsDefinitions are already in alphabetical order and are sufficient to obtain the values.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds 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.
