      Summary:
      In best-efforts recovery, an error that is not Corruption or IOError::kNotFound or IOError::kPathNotFound will be overwritten silently. Fix this by checking all non-ok cases and return early.

      Let best-efforts recovery ignore CURRENT file (#6970) · 97a69f43
      Yanqin Jin 创作于
      Summary:
      Best-efforts recovery does not check the content of CURRENT file to determine which MANIFEST to recover from. However, it still checks the presence of CURRENT file to determine whether to create a new DB during `open()`. Therefore, we can tweak the logic in `open()` a little bit so that best-efforts recovery does not rely on CURRENT file at all.

      Maintain the set of linked SSTs in BlobFileMetaData (#6945) · 83833637
      Levi Tamasi 创作于
      Summary:
      The `FileMetaData` objects associated with table files already contain the
      number of the oldest blob file referenced by the SST in question. This patch
      adds the inverse mapping to `BlobFileMetaData`, namely the set of table file
      numbers for which the oldest blob file link points to the given blob file (these
      are referred to as *linked SSTs*). This mapping will be used by the GC logic.
      
      Implementation-wise, the patch builds on the `BlobFileMetaDataDelta`
      functionality introduced in https://github.com/facebook/rocksdb/pull/6835: newly linked/unlinked SSTs are
      accumulated in `BlobFileMetaDataDelta`, and the changes to the linked SST set
      are applied in one shot when the new `Version` is saved. The patch also reworks
      the blob file related consistency checks in `VersionBuilder` so they validate the
      consistency of the forward table file -> blob file links and the backward blob file ->
      table file links for blob files that are part of the `Version`.

      Fail point-in-time WAL recovery upon IOError reading WAL (#6963) · 717749f4
      Yanqin Jin 创作于
      Summary:
      If `options.wal_recovery_mode == WALRecoveryMode::kPointInTimeRecovery`, RocksDB stops replaying WAL once hitting an error and discards the rest of the WAL. This can lead to data loss if the error occurs at an offset smaller than the last sync'ed offset.
      Ideally, RocksDB point-in-time recovery should permit recovery if the error occurs after last synced offset while fail recovery if error occurs before the last synced offset. However, RocksDB does not track the synced offset of WALs. Consequently, RocksDB does not know whether an error occurs before or after the last synced offset. An error can be one of the following.
      - WAL record checksum mismatch. This can result from both corruption of synced data and dropping of unsynced data during shutdown. We cannot be sure which one. In order not to defeat the original motivation to permit the latter case, we keep the original behavior of point-in-time WAL recovery.
      - IOError. This means the WAL can be bad, an indicator of whole file becoming unavailable, not to mention synced part of the WAL. Therefore, we choose to modify the behavior of point-in-time recovery and fail the database recovery.

      Revisit the handling of the case when a file is re-added to the same level (#6939) · d854abad
      Levi Tamasi 创作于
      Summary:
      https://github.com/facebook/rocksdb/pull/6901 subtly changed the handling of the corner case
      when a table file is deleted from a level, then re-added to the same level. (Note: this
      should be extremely rare; one scenario that comes to mind is a trivial move followed by
      a call to `ReFitLevel` that moves the file back to the original level.) Before that change,
      a new `FileMetaData` object was created as a result of this sequence; after the change,
      the original `FileMetaData` was essentially resurrected (since the deletion and the addition
      simply cancel each other out with the change). This patch restores the original behavior,
      which is more intuitive considering the interface, and in sync with how trivial moves are handled.
      (Also note that `FileMetaData` contains some mutable data members, the values of which
      might be different in the resurrected object and the freshly created one.)
      The PR also fixes a bug in this area: with the original pre-6901 code, `VersionBuilder`
      would add the same file twice to the same level in the scenario described above.

      Ingest SST files with checksum information (#6891) · b3585a11
      Zhichao Cao 创作于
      Summary:
      Application can ingest SST files with file checksum information, such that during ingestion, DB is able to check data integrity and identify of the SST file. The PR introduces generate_and_verify_file_checksum to IngestExternalFileOption to control if the ingested checksum information should be verified with the generated checksum.
      
          1. If generate_and_verify_file_checksum options is *FALSE*: *1)* if DB does not enable SST file checksum, the checksum information ingested will be ignored; *2)* if DB enables the SST file checksum and the checksum function name matches the checksum function name in DB, we trust the ingested checksum, store it in Manifest. If the checksum function name does not match, we treat that as an error and fail the IngestExternalFile() call.
          2. If generate_and_verify_file_checksum options is *TRUE*: *1)* if DB does not enable SST file checksum, the checksum information ingested will be ignored; *2)* if DB enable the SST file checksum, we will use the checksum generator from DB to calculate the checksum for each ingested SST files after they are copied or moved. Then, compare the checksum results with the ingested checksum information: _A)_ if the checksum function name does not match, _verification always report true_ and we store the DB generated checksum information in Manifest. _B)_ if the checksum function name mach, and checksum match, ingestion continues and stores the checksum information in the Manifest. Otherwise, terminate file ingestion and report file corruption.

      save a key comparison in block seeks (#6646) · e6be168a
      Andrew Kryczka 创作于
      Summary:
      This saves up to two key comparisons in block seeks. The first key
      comparison saved is a redundant key comparison against the restart key
      where the linear scan starts. This comparison is saved in all cases
      except when the found key is in the first restart interval. The
      second key comparison saved is a redundant key comparison against the
      restart key where the linear scan ends. This is only saved in cases
      where all keys in the restart interval are less than the target
      (probability roughly `1/restart_interval`).

      It appears that when running as the first test, PeakId() was updated twice. I didn't dig into it why but it doesn't seem to break the contract. Relax the assertion to make it pass.

      Fix two core dumps when files are missing (#6922) · e85cbdb4
      mrambacher 创作于
      Summary:
      The LDB create and drop column family commands failed to check if theere was a valid database prior to dereferencing it, leading to a core dump.
      
      The SstFileDumper prefetch code would dereference a file when the file did not exist as part of the Prefetch code.  This dereference was moved inside an st.ok() check.
      
      Tests were added for both failure conditions.

      API change: DB::OpenForReadOnly will not write to the file system unless create_if_missing is true (#6900)
      
      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

      Make sure core components not depend on gtest (#6921) · 055b4d25
      sdong 创作于
      Summary:
      We recently removed the dependencies of core components on gtest. Add a Travis test to make sure it doesn't regress. Change cmake setting so that the gtest related components are only included when tests, benchmarks or stress tools are included in the build. Add this build setting in Travis to confirm it.

      Revert "Update googletest from 1.8.1 to 1.10.0 (#6808)" (#6923) · afa35188
      sdong 创作于
      Summary:
      This reverts commit 8d87e9ce.
      
      Based on offline discussions, it's too early to upgrade to gtest 1.10, as it prevents some developers from using an older version of gtest to integrate to some other systems. Revert it for now.

      Route GetTestDirectory to FileSystem in CompositeEnvWrappers (#6896) · 0f85d163
      Hans Holmberg 创作于
      Summary:
      GetTestDirectory implies a file system operation (it creates the
      default test directory if missing), so it should be routed to
      the FileSystem rather than the Env.
      
      Also remove the GetTestDirectory implementation in the PosixEnv,
      since it overrides GetTestDirectory in CompositeEnv making it
      impossible to override with a custom FileSystem.
