Windows, bootstrapping: fix bugs to support Cygwin We can't yet fully bootstrap Bazel on Cygwin, but can build Bazel from scratch. Building Bazel with Bazel fails because gcc isn't found where it's believed to be -- /usr/bin is a mount in Cygwin (to /bin), not a symlink or directory. In this change I: - added support for the Cygwin shell as a bootstrap platform (recognize `uname`) - updateed the bootstrap scripts to use "windows" as the PLATFORM string, not "mingw" - fixed the git lookup code - removed some hardwired msys-style path - added a cygpath call to convert $PWD to a mixed-style (otherwise the bootstrap script passes --client_cwd=/cygdrive/c/... to the server and WindowsFileSystem.java wants to make that relative to c:/cygwin64) See https://github.com/bazelbuild/bazel/issues/2885 Change-Id: Icc71261ea4f0c6d4a9c0846551a7977ca6020331 PiperOrigin-RevId: 154273014
{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.
