Summary:
In preparation for more support for file Temperatures in BackupEngine,
this change does some test refactoring:
* Move DBTest2::BackupFileTemperature test to
BackupEngineTest::FileTemperatures, with some updates to make it work
in the new home. This test will soon be expanded for deeper backup work.
* Move FileTemperatureTestFS from db_test2.cc to db_test_util.h, to
support sharing because of above moved test, but split off the "no link"
part to the test needing it.
* Use custom FileSystems in backupable_db_test rather than custom Envs,
because going through Env file interfaces doesn't support temperatures.
* Fix RemapFileSystem to map DirFsyncOptions::renamed_new_name
parameter to FsyncWithDirOptions, which was required because this
limitation caused a crash only after moving to higher fidelity of
FileSystem interface (vs. LegacyDirectoryWrapper throwing away some
parameter details)
* `backupable_options_` -> `engine_options_` as part of the ongoing
work to get rid of the obsolete "backupable" naming.

Summary:
**Context:**
`DBLogicalBlockSizeCacheTest.CreateColumnFamilies` is flaky on a rare occurrence of assertion failure below
```
db/db_logical_block_size_cache_test.cc:210
Expected equality of these values:
1
cache_->GetRefCount(cf_path_0_)
Which is: 2
```
Root-cause: `ASSERT_OK(db->DestroyColumnFamilyHandle(cfs[0]));` in the test may not successfully decrease the ref count of `cf_path_0_` since the decreasing only happens in the clean-up of `ColumnFamilyData` when `ColumnFamilyData` has no referencing to it, which may not be true when `db->DestroyColumnFamilyHandle(cfs[0])` is called since background work such as `DumpStats()` can hold reference to that `ColumnFamilyData` (suggested and repro-d by ajkr ). Similar case `ASSERT_OK(db->DestroyColumnFamilyHandle(cfs[1]));`.
See following for a deterministic repro:

Summary:
This bug affects use cases that meet the following conditions
- (has only the default column family or disables WAL) and
- has at least one event listener
- atomic flush is NOT affected.
If the above conditions meet, then RocksDB can release the db mutex before picking all the
existing memtables to flush. In the meantime, a snapshot can be created and db's sequence
number can still be incremented. The upcoming flush will ignore this snapshot.
A later read using this snapshot can return incorrect result.
To fix this issue, we call the listeners callbacks after picking the memtables so that we avoid
creating snapshots during this interval.

Summary:
Fix g++ -march=native detection and reenable s390x in travis
This PR fixes s390x assembler messages:
```
Error: invalid switch -march=z14
Error: unrecognized option -march=z14
```
The s390x travis build was failing with gcc-7 because the assembler on
ubuntu 16.04 is too old to recognize the z14 model so it doesn't work
with -march=native on a z14 machine. It fixes the check for the
-march=native flag so that the assembler will get called and correctly
fail on ubuntu 16.04 which will cause the build to fall back to
-march=z196 which works.
The other changes are needed so builds work more consistently on
s390x:
1. Set make parallelism to 1 for s390x: The default was 4 previously
but I saw frequent internal compiler errors on travis probably due to
low resources. The `platform_dependent` job works more consistently
but is roughly 10 minutes slower although it varies.
2. Remove status_checked jobs, as we are relying on CircleCI for
these now and do not really need platform coverage on them.

The bug causes libxml2's HTML4 parser to fail to recover when encountering a bare <code><</code> character in some contexts. This version of Nokogiri restores the earlier behavior, which is to recover from the parse error and treat the <code><</code> as normal character data (which will be serialized as <code>&lt;</code> in a text node). The bug (and the fix) is only relevant when the <code>RECOVER</code> parse option is set, as it is by default.

<h2>1.13.0 / 2022-01-06</h2>
<h3>Notes</h3>
<h4>Ruby</h4>
<p>This release introduces native gem support for Ruby 3.1. Please note that Windows users should use the <code>x64-mingw-ucrt</code> platform gem for Ruby 3.1, and <code>x64-mingw32</code> for Ruby 2.6–3.0 (see <a href="https://rubyinstaller.org/2021/12/31/rubyinstaller-3.1.0-1-released.html">RubyInstaller 3.1.0 release notes</a>).</p>
<p>This release ends support for:</p>
<ul>
<li>Ruby 2.5, for which <a href="https://www.ruby-lang.org/en/downloads/branches/">official support ended 2021-03-31</a>.</li>
<li>JRuby 9.2, which is a Ruby 2.5-compatible release.</li>
</ul>
<h4>Faster, more reliable installation: Native Gem for ARM64 Linux</h4>
<p>This version of Nokogiri ships experimental native gem support for the <code>aarch64-linux</code> platform, which should support AWS Graviton and other ARM Linux platforms. We don't yet have CI running for this platform, and so we're interested in hearing back from y'all whether this is working, and what problems you're seeing. Please send us feedback here: <a href="https://github.com/sparklemotion/nokogiri/discussions/2359">Feedback: Have you used the <code>aarch64-linux</code> native gem?</a></p>

```
The problem occurred in `ApproximateSize()` when the index `Seek()` for the first `ApproximateDataOffsetOf()` encountered an I/O error, while the second `Seek()` did not. In the old code that scenario caused `start_offset == data_size` , thus it was easy to trip the assertion that `end_offset >= start_offset`.
The fix is to set `start_offset == 0` when the first index `Seek()` fails, and `end_offset == data_size` when the second index `Seek()` fails. I doubt these give an "on average correct" answer for how this function is used, but I/O errors in index seeks are hopefully rare, it looked consistent with what was already there, and it was easier to calculate.

Summary:
We found a case of cacheline bouncing due to writers locking/unlocking `mutex_` and readers accessing `block_cache_tracer_`. We discovered it only after the issue was fixed by https://github.com/facebook/rocksdb/issues/9462 shifting the `DBImpl` members such that `mutex_` and `block_cache_tracer_` were naturally placed in separate cachelines in our regression testing setup. This PR forces the cacheline alignment of `mutex_` so we don't accidentally reintroduce the problem.

Summary:
**Context:**
As part of https://github.com/facebook/rocksdb/pull/6949, file deletion is disabled for faulty database on the IOError of MANIFEST write/sync and [re-enabled again during `DBImpl::Resume()` if all recovery is completed](e66199d848 (diff-d9341fbe2a5d4089b93b22c5ed7f666bc311b378c26d0786f4b50c290e460187R396)). Before re-enabling file deletion, it `assert(versions_->io_status().ok());`, which IMO assumes `versions_` is **the** `version_` in the recovery process.
However, this is not necessarily true due to `s = error_handler_.ClearBGError();` happening before that assertion can unblock some foreground thread by [`EventHelpers::NotifyOnErrorRecoveryEnd()`](3122cb4358/db/error_handler.cc (L552-L553)) as part of the `ClearBGError()`. That foreground thread can do whatever it wants including closing/reopening the db and clean up that same `versions_`.
As a consequence, `assert(versions_->io_status().ok());`, will access `io_status()` of a nullptr and test like `DBErrorHandlingFSTest.MultiCFWALWriteError` becomes flaky. The unblocked foreground thread (in this case, the testing thread) proceeds to [reopen the db](https://github.com/facebook/rocksdb/blob/6.29.fb/db/error_handler_fs_test.cc?fbclid=IwAR1kQOxSbTUmaHQPAGz5jdMHXtDsDFKiFl8rifX-vIz4B23Y0S9jBkssSCg#L1494), where [`versions_` gets reset to nullptr](https://github.com/facebook/rocksdb/blob/6.29.fb/db/db_impl/db_impl.cc?fbclid=IwAR2uRhwBiPKgmE9q_6CM2mzbfwjoRgsGpXOrHruSJUDcAKc9rYZtVSvKdOY#L678) as part of the old db clean-up. If this happens right before `assert(versions_->io_status().ok()); ` gets excuted in the background thread, then we can see error like
```
db/db_impl/db_impl.cc:420:5: runtime error: member call on null pointer of type 'rocksdb::VersionSet'
assert(versions_->io_status().ok());
```
**Summary:**
- I proposed to call `s = error_handler_.ClearBGError();` after we know it's fine to wake up foreground, which I think is right before we LOG `ROCKS_LOG_INFO(immutable_db_options_.info_log, "Successfully resumed DB");`
- As the context, the orignal https://github.com/facebook/rocksdb/pull/3997 introducing `DBImpl::Resume()` calls `s = error_handler_.ClearBGError();` very close to calling `ROCKS_LOG_INFO(immutable_db_options_.info_log, "Successfully resumed DB");` while the later https://github.com/facebook/rocksdb/pull/6949 distances these two calls a bit.
- And it seems fine to me that `s = error_handler_.ClearBGError();` happens after `EnableFileDeletions(/*force=*/true);` at least syntax-wise since these two functions are orthogonal. And it also seems okay to me that we re-enable file deletion before `s = error_handler_.ClearBGError();`, which basically is resetting some state variables.
- In addition, to preserve the previous behavior of https://github.com/facebook/rocksdb/pull/6949 where status of re-enabling file deletion is not taken account into the general status of resuming the db, I separated `enable_file_deletion_s` from the general `s`
- In addition, to make `ROCKS_LOG_INFO(immutable_db_options_.info_log, "Successfully resumed DB");` more clear, I separated it into its own if-block.

Summary:
Implement a streaming compression API (compress/uncompress) to use for WAL compression. The log_writer would use the compress class/API to compress a record before writing it out in chunks. The log_reader would use the uncompress class/API to uncompress the chunks and combine into a single record.
Added unit test to verify the API for different sizes/compression types.

Summary:
**Summary:**
RocksDB uses a block cache to reduce IO and make queries more efficient. The block cache is based on the LRU algorithm (LRUCache) and keeps objects containing uncompressed data, such as Block, ParsedFullFilterBlock etc. It allows the user to configure a second level cache (rocksdb::SecondaryCache) to extend the primary block cache by holding items evicted from it. Some of the major RocksDB users, like MyRocks, use direct IO and would like to use a primary block cache for uncompressed data and a secondary cache for compressed data. The latter allows us to mitigate the loss of the Linux page cache due to direct IO.
This PR includes a concrete implementation of rocksdb::SecondaryCache that integrates with compression libraries such as LZ4 and implements an LRU cache to hold compressed blocks.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9518
Test Plan:
In this PR, the lru_secondary_cache_test.cc includes the following tests:
1. The unit tests for the secondary cache with either compression or no compression, such as basic tests, fails tests.
2. The integration tests with both primary cache and this secondary cache .
**Follow Up:**
1. Statistics (e.g. compression ratio) will be added in another PR.
2. Once this implementation is ready, I will do some shadow testing and benchmarking with UDB to measure the impact.

Summary:
This PR supports inserting keys to a `WriteBatchWithIndex` for column families that enable user-defined timestamps
and reading the keys back. **The index does not have timestamps.**
Writing a key to WBWI is unchanged, because the underlying WriteBatch already supports it.
When reading the keys back, we need to make sure to distinguish between keys with and without timestamps before
comparison.
When user calls `GetFromBatchAndDB()`, no timestamp is needed to query the batch, but a timestamp has to be
provided to query the db. The assumption is that data in the batch must be newer than data from the db.

Summary:
We often see flaky tests due to `DB::Flush()` or `DBImpl::TEST_WaitForFlushMemTable()` not waiting until event listeners complete. For example, https://github.com/facebook/rocksdb/issues/9084, https://github.com/facebook/rocksdb/issues/9400, https://github.com/facebook/rocksdb/issues/9528, plus two new ones this week: "EventListenerTest.OnSingleDBFlushTest" and "DBFlushTest.FireOnFlushCompletedAfterCommittedResult". I ran a `make check` with the below race condition-coercing patch and fixed issues it found besides old BlobDB.
```
diff --git a/db/db_impl/db_impl_compaction_flush.cc b/db/db_impl/db_impl_compaction_flush.cc

{

info->triggered_writes_slowdown = triggered_writes_slowdown;
```
The reason I did not fix old BlobDB issues is because it appears to have a fundamental (non-test) issue. In particular, it uses an EventListener to keep track of the files. OnFlushCompleted() could be delayed until even after a compaction involving that flushed file completes, causing the compaction to unexpectedly delete an untracked file.

Summary:
This PR adds support for new APIs Async Read that reads the data
asynchronously and Poll API that checks if requested read request has
completed or not.
Usage: In RocksDB, we are currently planning to prefetch data
asynchronously during sequential scanning and RocksDB will call these
APIs to prefetch more data in advanced.
Design:
- ReadAsync API submits the read request to underlying FileSystem in
order to read data asynchronously. When read request is completed,
callback function will be called. cb_arg is used by RocksDB to track the
original request submitted and IOHandle is used by FileSystem to keep track
of IO requests at their level.
- The Poll API is added in FileSystem because the call could end up handling
completions for multiple different files which is not specific to a
FSRandomAccessFile instance. There could be multiple outstanding file reads
from different files in future and they can complete in any order.

Test Plan: Test will be added in separate PR.

Summary:
[Compaction::IsTrivialMove](a2b9be42b6/db/compaction/compaction.cc (L318)) checks whether allow_trivial_move is set, and if so it returns the value of is_trivial_move_. The allow_trivial_move option is there for universal compaction. So when this is set and leveled compaction is enabled, then useful code that follows this block never gets a chance to run.
A check that [compaction_style == kCompactionStyleUniversal](320d9a8e8a/db/db_impl/db_impl_compaction_flush.cc (L1030)) should be added to avoid doing the wrong thing for leveled.

Summary:
Extend the plugin architecture to allow for the inclusion, building and testing of Java and JNI components of a plugin. This will cause the JAR built by `$ make rocksdbjava` to include the extra functionality provided by the plugin, and will cause `$ make jtest` to add the java tests provided by the plugin to the tests built and run by Java testing.
The plugin's `<plugin>.mk` file can define:
```
<plugin>_JNI_NATIVE_SOURCES
<plugin>_NATIVE_JAVA_CLASSES
<plugin>_JAVA_TESTS
```
The plugin should provide java/src, java/test and java/rocksjni directories. When a plugin is required to be build it must be named in the ROCKSDB_PLUGINS environment variable (as per the plugin architecture). This now has the effect of adding the files specified by the above definitions to the appropriate parts of the build.
An example of a plugin with a Java component can be found as part of the hdfs plugin in https://github.com/riversand963/rocksdb-hdfs-env - at the time of writing the Java part of this fails tests, and needs a little work to complete, but it builds correctly under the plugin model.
