Summary: * Don't hardcode namespace rocksdb (use ROCKSDB_NAMESPACE) * Don't #include <rocksdb/...> (use double quotes) * Support putting NOCOMMIT (any case) in source code that should not be committed/pushed in current state. These will be run with `make check` and in GitHub actions Pull Request resolved: https://github.com/facebook/rocksdb/pull/8821 Test Plan: existing tests, manually try out new checks Reviewed By: zhichao-cao Differential Revision: D30791726 Pulled By: pdillinger fbshipit-source-id: 399c883f312be24d9e55c58951d4013e18429d92
