Stop "no generating action" exceptions for configurable cc_library "srcs". The underlying problem is that Bazel determines whether or not to generate a .so by the contents of "srcs", but this happens in the loading phase before configurations are known. So, when "srcs" is configurable, it conservatively assumes a .so needs to be generated. In cc_library analysis, when the final values for "srcs" is properly bound, the .so may not actually be needed after all. This cl fixes the discrepancy by registering a FailAction for the .so under those circumstances - we don't actually need the .so anywhere but we still have to ensure it's registered with an owning action. -- MOS_MIGRATED_REVID=96405079
{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.
