Peter Dillinger 4b18c46d10 Refactor: add LineFileReader and Status::MustCheck (#8026) ... Summary: Removed confusing, awkward, and undocumented internal API ReadOneLine and replaced with very simple LineFileReader. In refactoring backupable_db.cc, this has the side benefit of removing the arbitrary cap on the size of backup metadata files. Also added Status::MustCheck to make it easy to mark a Status as "must check." Using this, I can ensure that after LineFileReader::ReadLine returns false the caller checks GetStatus(). Also removed some excessive conditional compilation in status.h Pull Request resolved: https://github.com/facebook/rocksdb/pull/8026 Test Plan: added unit test, and running tests with ASSERT_STATUS_CHECKED Reviewed By: mrambacher Differential Revision: D26831687 Pulled By: pdillinger fbshipit-source-id: ef749c265a7a26bb13cd44f6f0f97db2955f6f0f		2021-03-09 20:12:38 -08:00
