Fix StackOverflowError on Windows. Fixes #5730 We found that with JDK9 and up Bazel would sometimes crash with a StackOverflowError in one of the Command-Accumulator-Thread-* threads. We experimentally found that this error was due to these threads being constrained to a 32KiB stack size. The default stack size for JVM threads on most 64-bit systems is 1MiB (So that's 3% of the default). The purpose of the Command-Accumulator-Threads is to read stdout/stderr from processes that Bazel launches locally. The proposed fix is to just use the system default stack size for these threads. The alternative is to increase the size limit to some arbitrary number that happens to work, but this is likely premature optimization and I'd like to avoid that if possible. We further found that this code even predates Blaze/Bazel and is from 2005. PiperOrigin-RevId: 208009940
{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.
One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.
Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.
Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
