Bazel bootstrapping: consume custom startup flags The bootstrap build is special in that it does not use the Bazel client hence we cannot pass a --bazelrc flag as there'd be nothing to parse it. While Bazel is being bootstrapped it's nice to have colors on a smart terminal, but when the bootstrapping is done by Jenkins as part of a CI test, we need the output to be readable, i.e. be free of control characters, so we should pass --colors=no for example. By exporting BAZEL_BOOTSTRAP_STARTUP_OPTIONS the user can control what startup flags will the bootstrap build use, so we can pass these dumbing-down flags during CI builds. -- MOS_MIGRATED_REVID=134273969
{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.
