Summary:
Before this fix, atomic flush codepath may hit an assertion failure on a specific failure case.
If all flush jobs within an atomic flush succeed (they do not write to MANIFEST), but batch writing version edits to MANIFEST fails, then `cfd->imm()->RollbackMemTableFlush()` will be called twice, and the second invocation hits assertion failure `assert(m->flush_in_progress_)` since the first invocation resets the variable `flush_in_progress_` to false already.
Test plan (dev server):
```
./db_flush_test --gtest_filter=DBAtomicFlushTest/DBAtomicFlushTest.RollbackAfterFailToInstallResults
make check
```
Both must succeed.

Summary:
In `DBSSTTest.SSTsWithLdbSuffixHandling`, some sst files are renamed to ldb files, the original intention of the test is to test that the ldb files can be loaded along with the sst files.
The original test checks this by `ASSERT_NE("NOT_FOUND", Get(Key(k)))`, but the problem is `Get(Key(k))` returns IO error due to path not found instead of NOT_FOUND, so the success of ASSERT_NE does not mean the key can be retrieved.
This PR updates the test to make sure Get(Key(k)) returns the original value.

Summary:
Before this PR it calls GetFileSize() once for each sst file in the DB. This can take a long time if there are be tens of thousands of sst files (e.g. in thousands of column families), and even longer if Env is talking to some remote service rather than local filesystem. This PR makes DB::Open() use sst file sizes that are already known from manifest (typically almost all files in the DB) and only call GetFileSize() for non-sst or obsolete files. Note that GetFileSize() is also called and checked against manifest in CheckConsistency(), so the calls in SstFileManagerImpl were completely redundant.

Summary:
When paranoid_checks is on, DBImpl::CheckConsistency() iterates over all sst files and calls Env::GetFileSize() for each of them. As far as I could understand, this is pretty arbitrary and doesn't affect correctness - if filesystem doesn't corrupt fsynced files, the file sizes will always match; if it does, it may as well corrupt contents as well as sizes, and rocksdb doesn't check contents on open.
If there are thousands of sst files, getting all their sizes takes a while. If, on top of that, Env is overridden to use some remote storage instead of local filesystem, it can be *really* slow and overload the remote storage service. This PR adds an option to not do GetFileSize(); instead it does GetChildren() for parent directory to check that all the expected sst files are at least present, but doesn't check their sizes.
We can't just disable paranoid_checks instead because paranoid_checks do a few other important things: make the DB read-only on write errors, print error messages on read errors, etc.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6353

Summary:
Fix for issue https://github.com/facebook/rocksdb/issues/6316
When an append/sync of the manifest file fails due to an IO error such
as NoSpace, we don't always put the DB in read-only mode. This is true
for flush and compactions, as well as foreground operatons such as column family
add/drop, CompactFiles etc. Subsequent changes to the DB will be
recorded in the same manifest file, which would have a corrupted record
in the middle due to the previous failure. On next DB::Open(), it will
fail to process the full manifest and data will be lost.
To fix this, we reset VersionSet::descriptor_log_ on append/sync
failure, which will force a new manifest file to be written on the next
append.

Summary:
In WritePrepared there could be gap in sequence numbers. This breaks the trick we use in kPointInTimeRecovery which assume the first seq in the log right after the corrupted log is one larger than the last seq we read from the logs. To let this trick keep working, we add a dummy entry with the expected sequence to the first log right after recovery.
Also in WriteCommitted, if the log right after the corrupted log is empty, since it has no sequence number to let the sequential trick work, it is assumed as unexpected behavior. This is however expected to happen if we close the db after recovering from a corruption and before writing anything new to it. To remedy that, we apply the same technique by writing a dummy entry to the log that is created after the corrupted log.

Summary:
https://github.com/facebook/rocksdb/pull/6028 introduces a bug for hash index in SST files. If a table reader is created when total order seek is used, prefix_extractor might be passed into table reader as null. While later when prefix seek is used, the same table reader used, hash index is checked but prefix extractor is null and the program would crash.
Fix the issue by fixing http://github.com/facebook/rocksdb/pull/6028 in the way that prefix_extractor is preserved but ReadOptions.total_order_seek is checked
Also, a null pointer check is added so that a bug like this won't cause segfault in the future.

Summary:
The earlier code used two conflicting definitions for the number of
input records going into a compaction, one based on the
`rocksdb.num.entries` table property and one based on
`CompactionIterationStats`. The first one is correct and in line
with how output records are counted, while the second one incorrectly
ignores input records in various cases when the `CompactionIterator`
advances or reseeks the input iterator (this can happen, amongst other
cases, when dealing with `SingleDelete`s, regular `Delete`s, `Merge`s,
and compaction filters). This can result in the code undercounting the
input records and computing an incorrect value for "records dropped"
during the compaction. The patch fixes this by switching over to the
correct (table property based) input record count for "records dropped".

Summary:
This is a simple edit to have two #include file paths be consistent within range_del_aggregator.{h,cc} with everywhere else.
The impact of this inconsistency is that it actual breaks a Bazel based build on the Windows platform. The same pragma once failure occurs with both Windows Visual C++ 2019 and clang for Windows 9.0. Bazel's "sandboxing" of the builds causes both compilers to not properly recognize "rocksdb/types.h" and "include/rocksdb/types.h" to be the same file (also comparator.h). My guess is that the backslash versus forward slash mixing within path names is the underlying issue.
But, everything builds fine once the include paths in these two source files are consistent with the rest of the repository.

Summary:
When prefix is enabled the expected behavior when the prefix of the target does not exist is for Seek is to seek to any key larger than target and SeekToPrev to any key less than the target.
Currently. the prefix index (kHashSearch) returns OK status but sets Invalid() to indicate two cases: a prefix of the searched key does not exist, ii) the key is beyond the range of the keys in SST file. The SeekForPrev implementation in BlockBasedTable thus does not have enough information to know when it should set the index key to first (to return a key smaller than target). The patch fixes that by returning NotFound status for cases that the prefix does not exist. SeekForPrev in BlockBasedTable accordingly SeekToFirst instead of SeekToLast on the index iterator.

unordered_write is incompatible with non-zero max_successive_merges. Although we check this at runtime, we currently don't prevent the user from setting this combination in options. This has led to stress tests to fail with this combination is tried in ::SetOptions.
The patch fixes that and also reverts the changes performed by https://github.com/facebook/rocksdb/pull/6254, in which max_successive_merges was mistakenly declared incompatible with unordered_write.

Summary:
Currently, the recently-added test DBTest2.SwitchMemtableRaceWithNewManifest
fails in LITE mode since SetOptions() returns "Not supported". I do not want to
put `#ifndef ROCKSDB_LITE` because it reduces test coverage. Instead, just
trigger compaction on a different column family. The bg compaction thread
calling LogAndApply() may race with thread calling SwitchMemtable().
Test Plan (dev server):
make check
OPT=-DROCKSDB_LITE make check
or run DBTest2.SwitchMemtableRaceWithNewManifest 100 times.

Summary:
It seems that the C-API doesn't expose the range delete functionality at the moment, so add the API.

Summary:
When measure_io_stats_ is enabled, the volume of logging is beyond the default limit of 512 size. The patch allows the EventLoggerStream to change the limit, and also sets it to 1024 for FlushJob.

Summary:
level passed into ColumnFamilyData::CalculateSSTWriteHint() can be smaller than base_level in current version, which would cause overflow.
We see ubsan complains:
db/compaction/compaction_job.cc:1511:39: runtime error: load of value 4294967295, which is not a valid value for type 'Env::WriteLifeTimeHint'
and I hope this commit fixes it.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6212
Test Plan: Run existing tests and see them to pass.
