Make Bazel build dot This change has several parts, it: * Adds a "make" repository rule, which runs ./configure && make on a repository. * Modifies the tar.gz decompressor to restore timestamps. This was an issue with dot, as make examines the timestamp to determine if files need to be rebuilt. Because Bazel was not preserving the archive's timestamp, it was rebuilding things that it did not need to (and, I think, exposed some bugs in dot's Makefile). * Actually add dot as an external repository. I made the dot-graph target manual, so it won't be downloaded/built by the default //... target. * Remove dot scrubbing from the Bazel export process. * Added some names to download_and_extract params, because it's really annoying to only be able to reference them positionally. -- PiperOrigin-RevId: 142452055 MOS_MIGRATED_REVID=142452055
{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.
