Summary:
`FaultInjectionTest{Env,FS}::ReopenWritableFile()` functions were accidentally deleting WALs from previous `db_stress` runs causing verification to fail. They were operating under the assumption that `ReopenWritableFile()` would delete any existing file. It was a reasonable assumption considering the `{Env,FileSystem}::ReopenWritableFile()` documentation stated that would happen. The only problem was neither the implementations we offer nor the "real" clients in RocksDB code followed that contract. So, this PR updates the contract as well as fixing the fault injection client usage.
The fault injection change exposed that `ExternalSSTFileBasicTest.SyncFailure` was relying on a fault injection `Env` dropping unsynced data written by a regular `Env`. I changed that test to make its `SstFileWriter` use fault injection `Env`, and also implemented `LinkFile()` in fault injection so the unsynced data is tracked under the new name.

Add the file temperature to `IngestExternalFileArg` such that when SST files are ingested, user is able to assign the temperature to each SST file. If the temperature vector is empty or its size does not match the file name vector size, all ingested SST files will be assigned with `Temperature::unKnown`.

Summary:
I was looking at https://github.com/facebook/rocksdb/issues/2636 and got very confused that `MergingIterator::AddIterator()` is populating `min_heap_` with dangling pointers. There is justification in the comments that `min_heap_` will be cleared before it's used, but it'd be cleaner to not populate it with dangling pointers in the first place. Also made similar change in the constructor for consistency, although the pointers there would not be dangling, just unused.

Summary:
Background: Cache warming up will cause potential read performance degradation due to reading blocks from storage to the block cache. Since in production, the workload and access pattern to a certain DB is stable, it is a potential solution to dump out the blocks belonging to a certain DB to persist storage (e.g., to a file) and bulk-load the blocks to Secondary cache before the DB is relaunched. For example, when migrating a DB form host A to host B, it will take a short period of time, the access pattern to blocks in the block cache will not change much. It is efficient to dump out the blocks of certain DB, migrate to the destination host and insert them to the Secondary cache before we relaunch the DB.
Design: we introduce the interface of CacheDumpWriter and CacheDumpRead for user to store the blocks dumped out from block cache. RocksDB will encode all the information and send the string to the writer. User can implement their own writer it they want. CacheDumper and CacheLoad are introduced to save the blocks and load the blocks respectively.

Summary:
IOSTATS_ADD_IF_POSITIVE() doesn't seem to a macro that aims to improve performance but does the opposite. The counter to add is almost always positive so the if is just a waste. Furthermore, adding to a thread local variable seemse to be much cheaper than an if condition if branch prediction has a possibility to be wrong. Remove the macro.

Summary:
The ldb list_live_files_metadata command does not print any information about blob files currently. We would like to add this functionality. Note that list_live_files_metadata has two different modes of operation: the one shown above, which shows the LSM tree structure, and another one, which can be enabled using the flag --sort_by_filename and simply lists the files in numerical order regardless of level. We would like to show blob files in both modes.
Changes:
1. Using GetAllColumnFamilyMetaData API instead of GetLiveFilesMetaData API for fetching live files data.
Testing:
1. Created a sample rocksdb instance using dbbench command (this creates both SST and blob files)
2. Checked if the blob files are listed or not by using ldb commands.

Summary:
This is a precursor refactoring to enable an upcoming feature: persistence failure correctness testing.
- Changed `--expected_values_path` to `--expected_values_dir` and migrated "db_crashtest.py" to use the new flag. For persistence failure correctness testing there are multiple possible correct states since unsynced data is allowed to be dropped. Making it possible to restore all these possible correct states will eventually involve files containing snapshots of expected values and DB trace files.
- The expected values directory is managed by an `ExpectedStateManager` instance. Managing expected state files is separated out of `SharedState` to prevent `SharedState` from becoming too complex when the new files and features (snapshotting, tracing, and restoring) are introduced.
- Migrated expected values file access/management out of `SharedState` into a separate class called `ExpectedState`. This is not exposed directly to the test but rather the `ExpectedState` for the latest values file is accessed via a pass-through API on `ExpectedStateManager`. This forces the test to always access the single latest `ExpectedState`.
- Changed the initialization of the latest expected values file to use a tempfile followed by rename, and also add cleanup logic for possible stranded tempfiles.

Summary:
Context:
Exposing the level of the sst file (i.e, table) where it is created in `TablePropertiesCollectorFactory::Context` allows users of `TablePropertiesCollectorFactory` to customize some implementation details of `TablePropertiesCollectorFactory` and `TablePropertiesCollector` based on the level of creation. For example, `TablePropertiesCollector::NeedCompact()` can return different values based on level of creation.
- Declared an extra field `level_at_creation` in `TablePropertiesCollectorFactory::Context`
- Allowed `level_at_creation` to be passed in as an argument in `IntTblPropCollectorFactory::CreateIntTblPropCollector()` and `UserKeyTablePropertiesCollectorFactory::CreateIntTblPropCollector()`, the latter of which is an internal wrapper of user's passed-in `TablePropertiesCollectorFactory::CreateTablePropertiesCollector()` used in table-building process
- Called `IntTblPropCollectorFactory::CreateIntTblPropCollector()` with `level_at_creation` passed into both `BlockBasedTableBuilder` and `PlainTableBuilder`
- `PlainTableBuilder` previously did not capture `level_at_creation` from `TableBuilderOptions` in `PlainTableFactory`. In order for it to call the method with this parameter, this PR also made `PlainTableBuilder` capture `level_at_creation` as a required parameter
- Called `IntTblPropCollectorFactory::CreateIntTblPropCollector()` with `level_at_creation` its overridden functions in its derived classes, including `RegularKeysStartWithAFactory::CreateIntTblPropCollector()` in `table_properties_collector_test.cc`, `SstFileWriterPropertiesCollectorFactory::CreateIntTblPropCollector()` in `sst_file_writer_collectors.h`
Pull Request resolved: https://github.com/facebook/rocksdb/pull/8919
Test Plan:
- Passed the added assertion for `context.level_at_creation`
- Passed existing tests
- Run `Make` to make sure adding a required parameter to `PlainTableBuilder`'s constructor does not break anything

<h2>1.12.4 / 2021-08-29</h2>
<h3>Notable fix: Namespace inheritance</h3>
<p>Namespace behavior when reparenting nodes has historically been poorly specified and the behavior diverged between CRuby and JRuby. As a result, making this behavior consistent in v1.12.0 introduced a breaking change.</p>
<p>This patch release reverts the Builder behavior present in v1.12.0..v1.12.3 but keeps the Document behavior. This release also introduces a Document attribute to allow affected users to easily change this behavior for their legacy code without invasive changes.</p>
<h4>Compensating Feature in XML::Document</h4>
<p>This release of Nokogiri introduces a new <code>Document</code> boolean attribute, <code>namespace_inheritance</code>, which controls whether children should inherit a namespace when they are reparented. <code>Nokogiri::XML:Document</code> defaults this attribute to <code>false</code> meaning "do not inherit," thereby making explicit the behavior change introduced in v1.12.0.</p>
<p>CRuby users who desire the pre-v1.12.0 behavior may set <code>document.namespace_inheritance = true</code> before reparenting nodes.</p>
<p>See <a href="https://nokogiri.org/rdoc/Nokogiri/XML/Document.html#namespace_inheritance-instance_method">https://nokogiri.org/rdoc/Nokogiri/XML/Document.html#namespace_inheritance-instance_method</a> for example usage.</p>

<p>[JRuby] Address CVE-2021-41098 (<a href="https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-2rr5-8q37-2w7h">GHSA-2rr5-8q37-2w7h</a>).</p>
<p>In Nokogiri v1.12.4 and earlier, on JRuby only, the SAX parsers resolve external entities (XXE) by default. This fix turns off entity-resolution-by-default in the JRuby SAX parsers to match the CRuby SAX parsers' behavior.</p>
<p>CRuby users are not affected by this CVE.</p>
<h3>Fixed</h3>
<ul>
<li>[CRuby] <code>Document#to_xhtml</code> properly serializes self-closing tags in libxml > 2.9.10. A behavior change introduced in libxml 2.9.11 resulted in emitting start and and tags (e.g., <code><br></br></code>) instead of a self-closing tag (e.g., <code><br/></code>) in previous Nokogiri versions. [<a href="https://github-redirect.dependabot.com/sparklemotion/nokogiri/issues/2324">https://github.com/facebook/rocksdb/issues/2324</a>]</li>
</ul>
<h2>1.12.4 / 2021-08-29</h2>
<h3>Notable fix: Namespace inheritance</h3>
<p>Namespace behavior when reparenting nodes has historically been poorly specified and the behavior diverged between CRuby and JRuby. As a result, making this behavior consistent in v1.12.0 introduced a breaking change.</p>
<p>This patch release reverts the Builder behavior present in v1.12.0..v1.12.3 but keeps the Document behavior. This release also introduces a Document attribute to allow affected users to easily change this behavior for their legacy code without invasive changes.</p>
<h4>Compensating Feature in XML::Document</h4>
<p>This release of Nokogiri introduces a new <code>Document</code> boolean attribute, <code>namespace_inheritance</code>, which controls whether children should inherit a namespace when they are reparented. <code>Nokogiri::XML:Document</code> defaults this attribute to <code>false</code> meaning "do not inherit," thereby making explicit the behavior change introduced in v1.12.0.</p>
<p>CRuby users who desire the pre-v1.12.0 behavior may set <code>document.namespace_inheritance = true</code> before reparenting nodes.</p>
<p>See <a href="https://nokogiri.org/rdoc/Nokogiri/XML/Document.html#namespace_inheritance-instance_method">https://nokogiri.org/rdoc/Nokogiri/XML/Document.html#namespace_inheritance-instance_method</a> for example usage.</p>
<h4>Fix for XML::Builder</h4>
<p>However, recognizing that we want <code>Builder</code>-created children to inherit namespaces, Builder now will set <code>namespace_inheritance=true</code> on the underlying document for both JRuby and CRuby. This means that, on CRuby, the pre-v1.12.0 behavior is restored.</p>
<p>Users who want to turn this behavior off may pass a keyword argument to the Builder constructor like so:</p>
<pre lang="ruby"><code>Nokogiri::XML::Builder.new(namespace_inheritance: false)
</code></pre>
<p>See <a href="https://nokogiri.org/rdoc/Nokogiri/XML/Builder.html#label-Namespace+inheritance">https://nokogiri.org/rdoc/Nokogiri/XML/Builder.html#label-Namespace+inheritance</a> for example usage.</p>
<h4>Downstream gem maintainers</h4>
<p>Note that any downstream gems may want to specifically omit Nokogiri v1.12.0--v1.12.3 from their dependency specification if they rely on child namespace inheritance:</p>

Made SliceTransform into a Customizable class.
Would be nice to write a test that stored and used a custom transform in an SST table.
There are a set of tests (DBBlockFliterTest.PrefixExtractor*, SamePrefixTest.InDomainTest, PrefixTest.PrefixAndWholeKeyTest that run the same with or without a SliceTransform/PrefixFilter. Is this expected?

Summary:
The cyclic dependency was:
- `StressTest::OperateDb()` locks the mutex for key 'k'
- `StressTest::OperateDb()` calls a function like `PauseBackgroundWork()`, which waits for pending compaction to complete.
- The pending compaction reaches key `k` and `DbStressCompactionFilter::FilterV2()` calls `Lock()` on that key's mutex, which hangs forever.
The cycle can be broken by using a new function, `port::Mutex::TryLock()`, which returns immediately upon failure to acquire a lock. In that case `DbStressCompactionFilter::FilterV2()` can just decide to keep the key.

Summary:
Right now FaultInjectionTestFS::InjectThreadSpecificReadError() might try to corrupt return bytes, but these bytes might be from mmapped files, which would cause segfault. Instead FaultInjectionTestFS::InjectThreadSpecificReadError() should never corrupt data unless it is in caller's buffer.

Summary:
Context:
After more discussion, a fix in https://github.com/facebook/rocksdb/issues/8938 might turn out to be too restrictive for the case where `GetTotalPendingRequests` might be invoked on RateLimiter classes that does not support the recently added API `RateLimiter::GetTotalPendingRequests` (https://github.com/facebook/rocksdb/issues/8890) due to the `assert(false)` in https://github.com/facebook/rocksdb/issues/8938. Furthermore, sentinel value like `-1` proposed in https://github.com/facebook/rocksdb/issues/8938 is easy to be ignored and unchecked. Therefore we decided to adopt `Status::NotSupported()`, which is also a convention of adding new API to public header in RocksDB.
- Changed return value type of `RateLimiter::GetTotalPendingRequests` in related declaration/definition
- Passed in pointer argument to hold the output instead of returning it as before
- Adapted to the changes above in calling `RateLimiter::GetTotalPendingRequests` in test
- Minor improvement to `TEST_F(RateLimiterTest, GetTotalPendingRequests)`: added failure message for assertion and replaced repetitive statements with a loop

Summary:
There is a corner case when using WriteUnprepared transactions when
`WriteUnpreparedTxn::Get` returns `Status::TryAgain` instead of
propagating the result of `GetFromBatchAndDB`. The patch adds
`PermitUncheckedError` to make the `ASSERT_STATUS_CHECKED` build pass in
this case as well.

Summary:
Several improvements to MultiRead:
1. Fix a bug in stress test which causes false positive when both MultiRead() return and individual read request have failure injected.
2. Add two more types of fault that should be handled: empty read results and checksum mismatch
3. Add a message indicating which type of fault is injected
4. Increase the failure rate

Summary:
Right now, if underlying read returns fewer bytes than asked for, RandomAccessFileReader::MultiRead() still returns those in the buffer to upper layer. This can be a surprise to upper layer.
This is unlikely to cause incorrect data. To cause incorrect data, checksum checking in upper layer should pass with short reads, whose chance is low.
