Fix test flakiness. In the Bazel client's file_test, when testing multi-threaded pipe access, wait for all data to be written into the pipe. Pipes are not synchonization primitives in that read(2) returns immediately, reading as much data as it can, and won't block if it cannot read as much as requested. (This is even tested by the last ASSERT_EQ, trying to read 40 bytes.) This is however also true for the second ASSERT_EQ that attempts to read 5 bytes. The Send on the writer_thread is racing with the Receive on the main thread (as it should), and sometimes the main thread wins, resulting in fewer bytes received than previously expected. -- PiperOrigin-RevId: 142429243 MOS_MIGRATED_REVID=142429243
{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.
