13ae16c315 Cleanup includes in dbformat.h (#8930)
Summary:
This header file was including everything and the kitchen sink when it did not need to.  This resulted in many places including this header when they needed other pieces instead.

Cleaned up this header to only include what was needed and fixed up the remaining code to include what was now missing.

Hopefully, this sort of code hygiene cleanup will speed up the builds...

559943cdc0 Refactor expected state in stress/crash test (#8913)
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.

d6bd1a0291 Support "level_at_creation" in TablePropertiesCollectorFactory::Context (#8919)
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

b88109db19 Pollute buffer before calling Read() (#8955)
Summary:
Add a paranoid check where in case FileSystem layer doesn't fill the buffer but returns succeed, checksum is unlikely to match even if buffer contains a previous block. The byte modified is not useful anyway, so it isn't expect to change any behavior.

<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 &quot;do not inherit,&quot; 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>

<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>

Summary:
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?

791bff5b4e Prevent deadlock in db_stress with DbStressCompactionFilter (#8956)
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.

b25f2afeff Return Status::NotSupported() in RateLimiter::GetTotalPendingRequests default impl (#8950)
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:
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.

65411b8d4e Improve rate_limiter_test.cc (#8904)
Summary:
- Fixed a bug in `RateLimiterTest.GeneratePriorityIterationOrder` that the callbacks in this test were not called starting from `i = 1`. Fix by increasing `rate_bytes_per_sec` and requested bytes.
   - The bug is due to the previous `rate_bytes_per_sec` was set too small, resulting in `refill_bytes_per_period`  less than  `kMinRefillBytesPerPeriod`. Hence the actual `refill_bytes_per_period` was equal to `kMinRefillBytesPerPeriod` due to the logic [here](https://github.com/facebook/rocksdb/blob/main/util/rate_limiter.cc#L302-L303)  and it ended up being greater than the previously set requested bytes. Therefore starting from `i = 1`, `RefillBytesAndGrantRequests()` and `GeneratePriorityIterationOrder` won't be called and the test callbacks was not triggered to execute the assertion.
- Added internal flag to assert callbacks are called in `RateLimiterTest.GeneratePriorityIterationOrder` to prevent any future changes defeat the purpose of the test [as suggested](https://github.com/facebook/rocksdb/pull/8890#discussion_r704915134)
- Increased `rate_bytes_per_sec` and bytes of each request in `RateLimiterTest.GetTotalBytesThrough`, `RateLimiterTest.GetTotalRequests`, `RateLimiterTest.GetTotalPendingRequests` to trigger the "long path" of execution (i.e, the one trigger RefillBytesAndGrantRequests()) to increase test coverage
   - This increased the running time of the three tests, see test plan for time difference running locally
- Cleared up sync point effects after each test by calling `SyncPoint::GetInstance()->DisableProcessing();` and `SyncPoint::GetInstance()->ClearAllCallBacks();` in `~RateLimiterTest()` [as suggested](https://github.com/facebook/rocksdb/pull/8595/files#r697534279)
  - It's fine to call these two methods even when `EnableProcessing()` or `SetCallBack()` is not called in the test or is already cleaned up. In those cases, calling these two functions in destructor is effectively no-op.
  - This will allow cleaning up sync point effects of previous test even when the previous test failed in assertion.
- Added missing `SyncPoint::GetInstance()->DisableProcessing();` and `SyncPoint::GetInstance()->ClearCallBacks(..);` in existing tests for completeness
- Called `SyncPoint::GetInstance()->DisableProcessing();` and `SyncPoint::GetInstance()->ClearCallBacks(..);` in loop in `RateLimiterTest.GeneratePriorityIterationOrder` for completeness

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8904

Test Plan:
- Passing existing tests
- To verify the 1st change, run `RateLimiterTest.GeneratePriorityIterationOrder` with assertions of callbacks are indeed called under original `rate_bytes_per_sec` and request byte and under updated `rate_bytes_per_sec` and request byte. The former will fail the assertion while the latter succeeds.
- Here is the increased test time due to the 3rd change mentioned above in the summary. The relevant 3 tests mentioned in total increase the test time by 6s (~6000/33848 = 17.7% of the original total test time), which IMO is acceptable for better test coverage through running the "long path".

2819c7840e Fix PrepopulateBlockCache::kFlushOnly (#8750)
Summary:
kFlushOnly currently means "always" except in the case of
remote compaction. This makes it flushes only.

7743f033b1 More robust checking of IO uring completion data (#8894)
Summary:
Potential bugs in the IO uring implementation can cause bad data to be returned in the completion queue. Add some checks in the PosixRandomAccessFile::MultiRead completion handling code to catch such errors and fail the entire MultiRead. Also log some diagnostic messages and stack trace.

8df334342e Use the write amplification value calculated by RocksDB in benchmark.sh (#8915)
Summary:
Currently, `benchmark.sh` computes write amplification itself; the patch
changes the script to use the value calculated by RocksDB (which is
printed as part of the periodic statistics). This also has the benefit
of being correct for BlobDB as well, since it also considers the amount
of data written to blob files.

12d798ac06 Always iniitalize ArenaWrappedDBIter::db_iter_ to nullptr (#8889)
Summary:
ArenaWrappedDBIter::db_iter_ should never be nullptr. However, when debugging a segfault, it's hard to distinguish it is not initialized (not possible) and other corruption. Add this nullptr to help distinguish the case.

d648cb47b9 Adapt key-value checksum for timestamp-suffixed keys (#8914)
Summary:
After https://github.com/facebook/rocksdb/issues/8725, keys added to `WriteBatch` may be timestamp-suffixed, while `WriteBatch` has no awareness of the timestamp size. Therefore, `WriteBatch` can no longer calculate timestamp checksum separately from the rest of the key's checksum in all cases.

This PR changes the definition of key in KV checksum to include the timestamp suffix. That way we do not need to worry about where the timestamp begins within the key. I believe the only practical effect of this change is now `AssignTimestamp()` requires recomputing the whole key checksum (`UpdateK()`) rather than just the timestamp portion (`UpdateT()`).
