Hello everyone and welcome to this new decade! It’s already 2020 and I’m only 17 days late in writing a first post. I was planning to start with an opinion article, but as its draft is taking longer than I wanted… I’ll present you the story of a recent crazy bug that has kept me busy for the last couple of days. Java crashes with Bazel and sandboxfs On a machine running macOS Catalina, install sandboxfs and build Bazel with sandboxfs enabled, like this:
As strange as it may sound, a very important job of any build tool is to orchestrate the execution of lots of other programs—and Bazel is no exception. Once Bazel has finished loading and analyzing the build graph, Bazel enters the execution phase. In this phase, the primary thing that Bazel does is walk the graph looking for actions to execute. Then, for each action, Bazel invokes its commands—things like compiler and linker invocations—as subprocesses.
