Peter Dillinger 3d358a7e25 Fix handling of accidental truncation of IDENTITY file (#10173) ... Summary: A consequence of https://github.com/facebook/rocksdb/issues/9990 was requiring a non-empty DB ID to generate new SST files. But if the DB ID is not tracked in the manifest and the IDENTITY file is somehow truncated to 0 bytes, then an empty DB ID would be assigned, leading to crash. This change ensures a non-empty DB ID is assigned and set in the IDENTITY file. Also, * Some light refactoring to clean up the logic * (I/O efficiency) If the ID is tracked in the manifest and already matches the IDENTITY file, don't needlessly overwrite the file. * (Debugging) Log the DB ID to info log on open, because sometimes IDENTITY can change if DB is moved around (though it would be unusual for info log to be copied/moved without IDENTITY file) Pull Request resolved: https://github.com/facebook/rocksdb/pull/10173 Test Plan: unit tests expanded/updated Reviewed By: ajkr Differential Revision: D37176545 Pulled By: pdillinger fbshipit-source-id: a9b414cd35bfa33de48af322a36c24538d50bef1		3 years ago
