Summary: DB::OpenForReadOnly will not write anything to the file system (i.e., create directories or files for the DB) unless create_if_missing is true. This change also fixes some subcommands of ldb, which write to the file system even if the purpose is for readonly. Two tests for this updated behavior of DB::OpenForReadOnly are also added. Other minor changes: 1. Updated HISTORY.md to include this API change of DB::OpenForReadOnly; 2. Updated the help information for the put and batchput subcommands of ldb with the option [--create_if_missing]; 3. Updated the comment of Env::DeleteDir to emphasize that it returns OK only if the directory to be deleted is empty. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6900 Test Plan: passed make check; also manually tested a few ldb subcommands Reviewed By: pdillinger Differential Revision: D21822188 Pulled By: gg814 fbshipit-source-id: 604cc0f0d0326a937ee25a32cdc2b512f9a3be6e |
