Summary: Closes https://github.com/facebook/rocksdb/issues/7035 Changed how build_version.cc was generated: - Included the GIT tag/branch in the build_version file - Changed the "Build Date" to be: - If the GIT branch is "clean" (no changes), the date of the last git commit - If the branch is not clean, the current date - Added APIs to access the "build information", rather than accessing the strings directly. The build_version.cc file is now regenerated whenever the library objects are rebuilt. Verified that the built files remain the same size across builds on a "clean build" and the same information is reported by sst_dump --version Pull Request resolved: https://github.com/facebook/rocksdb/pull/7866 Reviewed By: pdillinger Differential Revision: D26086565 Pulled By: mrambacher fbshipit-source-id: 6fcbe47f6033989d5cf26a0ccb6dfdd9dd239d7f
