Summary:
Added a "only_mutable_options" flag to the ConfigOptions. When set, the Configurable methods will only look at/update options that are marked as kMutable.
Fixed DB::SetOptions to allow for the update of any mutable TableFactory options. Fixes https://github.com/facebook/rocksdb/issues/7385.
Added tests for the new flag. Updated HISTORY.md

Summary:
The trace file record and payload encode is fixed, which requires complex backward compatibility resolving. This PR introduce a new trace file format, which makes it easier to add new entries to the payload and does not have backward compatible issues. V 0.1 is still supported in this PR. Added the tracing for lower_bound and upper_bound for iterator.

Summary:
Fix this scenario:
trx1> acquire shared lock on $key
trx2> acquire shared lock on the same $key
trx1> attempt to acquire a unique lock on $key.
Lock acquisition will fail, and deadlock detection will start.
It will call iterate_and_get_overlapping_row_locks() which will
produce a list with two locks (shared locks by trx1 and trx2).
However the code in lock_request::build_wait_graph() was not prepared
to find the lock by the same transaction in the list of conflicting
locks. Fix it to ignore it.
(One may suggest to fix iterate_and_get_overlapping_row_locks() to not
include locks by trx1. This is not a good idea, because that function
is also used to report all locks currently held)

In this PR, we use the new API in WritableFileWriter, such that the file created via WritableFileWrite can pass the checksum to the storage layer. To control which types file should apply the checksum handoff, we add checksum_handoff_file_types to DBOptions. User can use this option to control which file types (Currently supported file tyes: kLogFile, kTableFile, kDescriptorFile.) should use the new Append and PositionedAppend APIs to handoff the verification information.

Adds support for prefetching data in Ribbon queries,
which especially optimizes batched Ribbon queries for MultiGet
(~222ns/key to ~97ns/key) but also single key queries on cold memory
(~333ns to ~226ns) because many queries span more than one cache line.
This required some refactoring of the query algorithm, and there
does not appear to be a noticeable regression in "hot memory" query
times (perhaps from 48ns to 50ns).

The patch fixes the build for `db_bench_tool_test` and makes the tests pass.
Namely, it fixes the following issues:
* https://github.com/facebook/rocksdb/issues/7703 removed the member variable `fs_` but the test case `OptionsFileMultiLevelUniversal`
was not updated.
* https://github.com/facebook/rocksdb/issues/7344 fixed the `OptionsFile` test case for the case when Snappy is *not* available but at the
same time broke it for the case when it *is* available. (The test used a default-constructed
`ColumnFamilyOptions` object, and the default value of the `compression` option is either
Snappy or no compression depending on whether Snappy is supported.)
* The test used `google::ParseCommandLineFlags` instead of
`GFLAGS_NAMESPACE::ParseCommandLineFlags`.

Summary:
The patch adds support for the options related to the new BlobDB implementation
to `db_stress`, including support for dynamically adjusting them using `SetOptions`
when `set_options_one_in` and a new flag `allow_setting_blob_options_dynamically`
are specified. (The latter is used to prevent the options from being enabled when
incompatible features are in use.)
The patch also updates the `db_stress` help messages of the existing stacked BlobDB
related options to clarify that they pertain to the old implementation. In addition, it
adds the new BlobDB to the crash test script. In order to prevent a combinatorial explosion
of jobs and still perform whitebox/blackbox testing (including under ASAN/TSAN/UBSAN),
and to also test BlobDB in conjunction with atomic flush and transactions, the script sets
the BlobDB options in 10% of normal/`cf_consistency`/`txn` crash test runs.

Summary:
There is a small `SingleDelete` related optimization in the
`CompactionIterator` code: when a `SingleDelete`-`Put` pair is preserved
solely for the purposes of transaction conflict checking, the value
itself gets cleared. (This is referred to as "optimization 3" in the
`CompactionIterator` code.) Though the rest of the code got updated to
support `SingleDelete`'ing blob indexes, this chunk was apparently
missed, resulting in an assertion failure (or `ROCKS_LOG_FATAL` in release
builds) when triggered. Note: in addition to clearing the value, we also
need to update the type of the KV to regular value when dealing with
blob indexes here.

Summary:
This PR adds the foundation classes for key-value integrity protection and the first use case: protecting live updates from the source buffers added to `WriteBatch` through the destination buffer in `MemTable`. The width of the protection info is not yet configurable -- only eight bytes per key is supported. This PR allows users to enable protection by constructing `WriteBatch` with `protection_bytes_per_key == 8`. It does not yet expose a way for users to get integrity protection via other write APIs (e.g., `Put()`, `Merge()`, `Delete()`, etc.).
The foundation classes (`ProtectionInfo.*`) embed the coverage info in their type, and provide `Protect.*()` and `Strip.*()` functions to navigate between types with different coverage. For making bytes per key configurable (for powers of two up to eight) in the future, these classes are templated on the unsigned integer type used to store the protection info. That integer contains the XOR'd result of hashes with independent seeds for all covered fields. For integer fields, the hash is computed on the raw unadjusted bytes, so the result is endian-dependent. The most significant bytes are truncated when the hash value (8 bytes) is wider than the protection integer.
When `WriteBatch` is constructed with `protection_bytes_per_key == 8`, we hold a `ProtectionInfoKVOTC` (i.e., one that covers key, value, optype aka `ValueType`, timestamp, and CF ID) for each entry added to the batch. The protection info is generated from the original buffers passed by the user, as well as the original metadata generated internally. When writing to memtable, each entry is transformed to a `ProtectionInfoKVOTS` (i.e., dropping coverage of CF ID and adding coverage of sequence number), since at that point we know the sequence number, and have already selected a memtable corresponding to a particular CF. This protection info is verified once the entry is encoded in the `MemTable` buffer.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/7748
Test Plan:
- an integration test to verify a wide variety of single-byte changes to the encoded `MemTable` buffer are caught
- add to stress/crash test to verify it works in variety of configs/operations without intentional corruption
- [deferred] unit tests for `ProtectionInfo.*` classes for edge cases like KV swap, `SliceParts` and `Slice` APIs are interchangeable, etc.

- If the branch is not clean, the current date
- Added APIs to access the "build information", rather than accessing the strings directly.
The build_version.cc file is now regenerated whenever the library objects are rebuilt.

Summary:
During recovery, RocksDB performs a kind of dummy flush; namely, entries
from the WAL are added to memtables, which then get written to SSTs and
blob files (if enabled) just like during a regular flush. Note that
multiple memtables might be flushed during recovery for the same column
family, for example, if the DB is reopened with a lower write buffer size,
and therefore, we need to make sure to collect all SST and blob file
additions. The patch fixes a bug in the earlier logic which resulted in
later blob file additions overwriting earlier ones.
