83833637c1 Maintain the set of linked SSTs in BlobFileMetaData (#6945)
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`.

717749f4c0 Fail point-in-time WAL recovery upon IOError reading WAL (#6963)
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.

d854abad78 Revisit the handling of the case when a file is re-added to the same level (#6939)
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.

b3585a11b4 Ingest SST files with checksum information (#6891)
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.

e6be168aa5 save a key comparison in block seeks (#6646)
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`).

largest key in the file, the next key cannot be present in that file.

3020df9df5 Remove unnecessary inclusion of version_edit.h in env (#6952)
Summary:
In db_options.c, we should avoid including header files in the `db` directory to avoid introducing unnecessary dependency. The reason why `version_edit.h` has been included in `db_options.cc` is because we need two constants, `kUnknownChecksum` and `kUnknownChecksumFuncName`. We can put these two constants as `constexpr` in the public header `file_checksum.h`.

e85cbdb4e8 Fix two core dumps when files are missing (#6922)
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.

02df00d97b 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

0f85d163e6 Route GetTestDirectory to FileSystem in CompositeEnvWrappers (#6896)
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.

172adce767 Posix threads (#6865)
Summary:
Rocksdb is using the c++11 std::threads feature. The issue is that
MINGW only supports it when using Posix threads.

This change will allow rocksdb::port::WindowsThread to be replaced
with std::thread, which in turn will allow Rocksdb to be cross
compiled using MINGW.

At the same time, we'll have to use GetCurrentProcessId instead of _getpid.

78e291b17e Improve consistency checks in VersionBuilder (#6901)
Summary:
The patch cleans up the code and improves the consistency checks around
adding/deleting table files in `VersionBuilder`. Namely, it makes the checks
stricter and improves them in the following ways:
1) A table file can now only be deleted from the LSM tree using the level it
resides on. Earlier, there was some unnecessary wiggle room for
trivially moved files (they could be deleted using a lower level number than
the actual one).
2) A table file cannot be added to the tree if it is already present in the tree
on any level (not just the target level). The earlier code only had an assertion
(which is a no-op in release builds) that the newly added file is not already
present on the target level.
3) The above consistency checks around state transitions are now mandatory,
as opposed to the earlier `CheckConsistencyForDeletes`, which was a no-op
in release mode unless `force_consistency_checks` was set to `true`. The rationale
here is that assuming that the initial state is consistent, a valid transition leads to a
next state that is also consistent; however, an *invalid* transition offers no such
guarantee. Hence it makes sense to validate the transitions unconditionally,
and save `force_consistency_checks` for the paranoid checks that re-validate
the entire state.
4) The new checks build on the mechanism introduced in https://github.com/facebook/rocksdb/pull/6862,
which enables us to efficiently look up the location (level and position within level)
of files in a `Version` by file number. This makes the consistency checks much more
efficient than the earlier `CheckConsistencyForDeletes`, which essentially
performed a linear search.

9360776cb9 Fix handling of too-small filter partition size (#6905)
Summary:
Because ARM and some other platforms have a larger cache line
size, they have a larger minimum filter size, which causes recently
added PartitionedMultiGet test in db_bloom_filter_test to fail on those
platforms. The code would actually end up using larger partitions,
because keys_per_partition_ would be 0 and never == number of keys
added.

The code now attempts to get as close as possible to the small target
size, while fully utilizing that filter size, if the target partition
size is smaller than the minimum filter size.

Also updated the test to break more uniformly across platforms
