Implement LcovMerger. LcovMerger is a tool that merges all the intermediate lcov tracefiles (with .dat extension) found under a coverage directory and prints the merged tracefile to a given output file. A custom implementation for merging lcov tracefiles is needed because the merging functionality of lcov itself is very slow. LcovMerger is required to get a single coverage report (lcov tracefile) from a bazel coverage command that executes multiple tests. ATM LcovMerger is only invoked by tools/test/collect_coverage.sh that collects and merges the tracefiles from a single test invocation. It will also be used from a CoverageReportAction. Progress on #5246. PiperOrigin-RevId: 200054506
{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.
