Introduce a new file-based logging handler for Bazel. It provides a number of features that we want and whose combination cannot be accomplished using the standard FileHandler: * Using a different filename per server process, by putting a timestamp and process ID in the filename. This means Bazel will no longer overwrite its log when the server is restarted, making it easier for developers and maintainers to diagnose issues. * Putting the hostname and username in the filename (useful when running on a shared network filesystem). * Automatically setting a symlink to the latest log file, ensuring that the latest log can still be found under the usual Bazel server log path. * Providing an API for getting the filename of the current log file, for use by Bazel itself. * Cleaning up old log files when their total size exceeds a set limit. This commit only introduces the handler; its usage in Bazel will be enabled by a follow-up commit. RELNOTES: None. PiperOrigin-RevId: 207274587
{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.
