a5063c8931 Fix issue of opening too many files in BlockBasedTableReaderCapMemoryTest.CapMemoryUsageUnderCacheCapacity (#9869)
Summary:
**Context:**
Unit test for https://github.com/facebook/rocksdb/pull/9748 keeps opening new files to see whether the new feature is able to correctly constrain the opening based on block cache capacity.

However, the unit test has two places written inefficiently that can lead to opening too many new files relative to underlying operating system/file system constraint, even before hitting the block cache capacity:
(1) [opened_table_reader_num < 2 * max_table_reader_num](https://github.com/facebook/rocksdb/pull/9748/files?show-viewed-files=true&file-filters%5B%5D=#diff-ec9f5353e317df71093094734ba29193b94a998f0f9c9af924e4c99692195eeaR438), which can leads to 1200 + open files because of (2) below
(2) NewLRUCache(6 * CacheReservationManagerImpl<CacheEntryRole::kBlockBasedTableReader>::GetDummyEntrySize()) in [here](https://github.com/facebook/rocksdb/pull/9748/files?show-viewed-files=true&file-filters%5B%5D=#diff-ec9f5353e317df71093094734ba29193b94a998f0f9c9af924e4c99692195eeaR364)

Therefore we see CI failures like this on machine with a strict open file limit ~1000 (see the "table_1021" naming in following error msg)
https://app.circleci.com/pipelines/github/facebook/rocksdb/12886/workflows/75524682-3fa4-41ee-9a61-81827b51d99b/jobs/345270
```

```

**Summary:**
- Revised the test more efficiently on the above 2 places,  including using 1.1 instead 2 in the threshold and lowering down the block cache capacity a bit
- Renamed some variables for clarity

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9869

Test Plan:
- Manual inspection of max opened table reader in all test case, which is around ~389
- Circle CI to see if error is gone

db536ee045 Propagate errors from UpdateBoundaries (#9851)
Summary:
In `FileMetaData`, we keep track of the lowest-numbered blob file
referenced by the SST file in question for the purposes of BlobDB's
garbage collection in the `oldest_blob_file_number` field, which is
updated in `UpdateBoundaries`. However, with the current code,
`BlobIndex` decoding errors (or invalid blob file numbers) are swallowed
in this method. The patch changes this by propagating these errors
and failing the corresponding flush/compaction. (Note that since blob
references are generated by the BlobDB code and also parsed by
`CompactionIterator`, in reality this can only happen in the case of
memory corruption.)

This change necessitated updating some unit tests that involved
fake/corrupt `BlobIndex` objects. Some of these just used a dummy string like
`"blob_index"` as a placeholder; these were replaced with real `BlobIndex`es.
Some were relying on the earlier behavior to simulate corruption; these
were replaced with `SyncPoint`-based test code that corrupts a valid
blob reference at read time.

0bd4dcde6b CompactionIterator sees consistent view of which keys are committed (#9830)
Summary:
**This PR does not affect the functionality of `DB` and write-committed transactions.**

`CompactionIterator` uses `KeyCommitted(seq)` to determine if a key in the database is committed.
As the name 'write-committed' implies, if write-committed policy is used, a key exists in the database only if
it is committed. In fact, the implementation of `KeyCommitted()` is as follows:

```
inline bool KeyCommitted(SequenceNumber seq) {
  // For non-txn-db and write-committed, snapshot_checker_ is always nullptr.
  return snapshot_checker_ == nullptr ||
         snapshot_checker_->CheckInSnapshot(seq, kMaxSequence) == SnapshotCheckerResult::kInSnapshot;
}
```

With that being said, we focus on write-prepared/write-unprepared transactions.

A few notes:
- A key can exist in the db even if it's uncommitted. Therefore, we rely on `snapshot_checker_` to determine data visibility. We also require that all writes go through transaction API instead of the raw `WriteBatch` + `Write`, thus at most one uncommitted version of one user key can exist in the database.
- `CompactionIterator` outputs a key as long as the key is uncommitted.

Due to the above reasons, it is possible that `CompactionIterator` decides to output an uncommitted key without
doing further checks on the key (`NextFromInput()`). By the time the key is being prepared for output, the key becomes
committed because the `snapshot_checker_(seq, kMaxSequence)` becomes true in the implementation of `KeyCommitted()`.
Then `CompactionIterator` will try to zero its sequence number and hit assertion error if the key is a tombstone.

To fix this issue, we should make the `CompactionIterator` see a consistent view of the input keys. Note that
for write-prepared/write-unprepared, the background flush/compaction jobs already take a "job snapshot" before starting
processing keys. The job snapshot is released only after the entire flush/compaction finishes. We can use this snapshot
to determine whether a key is committed or not with minor change to `KeyCommitted()`.

```
inline bool KeyCommitted(SequenceNumber sequence) {
  // For non-txn-db and write-committed, snapshot_checker_ is always nullptr.
  return snapshot_checker_ == nullptr ||
         snapshot_checker_->CheckInSnapshot(sequence, job_snapshot_) ==
             SnapshotCheckerResult::kInSnapshot;
}
```

As a result, whether a key is committed or not will remain a constant throughout compaction, causing no trouble
for `CompactionIterator`s assertions.

9454e744ed Update supported VS versions in INSTALL.md (#9823)
Summary:
We only run CI for VS2017 and VS2019 now, so the claim that users can build with "VS13" is stale.

7c7df1850a Update main version.h to NEXT release (#9834)
Summary:
Henceforth, the version number in version.h shall reflect the
*next* version number to be tagged (to the best of our knowledge) rather
than the *previous* (unpatched) version.

The primary advantage is being able to distinguish (in source code `#if`s
or human running tools) the development version from the last released
version.

efd035164b Meta-internal folly integration with F14FastMap (#9546)
Summary:
Especially after updating to C++17, I don't see a compelling case for
*requiring* any folly components in RocksDB. I was able to purge the existing
hard dependencies, and it can be quite difficult to strip out non-trivial components
from folly for use in RocksDB. (The prospect of doing that on F14 has changed
my mind on the best approach here.)

But this change creates an optional integration where we can plug in
components from folly at compile time, starting here with F14FastMap to replace
std::unordered_map when possible (probably no public APIs for example). I have
replaced the biggest CPU users of std::unordered_map with compile-time
pluggable UnorderedMap which will use F14FastMap when USE_FOLLY is set.
USE_FOLLY is always set in the Meta-internal buck build, and a simulation of
that is in the Makefile for public CI testing. A full folly build is not needed, but
checking out the full folly repo is much simpler for getting the dependency,
and anything else we might want to optionally integrate in the future.

Some picky details:
* I don't think the distributed mutex stuff is actually used, so it was easy to remove.
* I implemented an alternative to `folly::constexpr_log2` (which is much easier
in C++17 than C++11) so that I could pull out the hard dependencies on
`ConstexprMath.h`
* I had to add noexcept move constructors/operators to some types to make
F14's complainUnlessNothrowMoveAndDestroy check happy, and I added a
macro to make that easier in some common cases.
* Updated Meta-internal buck build to use folly F14Map (always)

No updates to HISTORY.md nor INSTALL.md as this is not (yet?) considered a
production integration for open source users.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9546

Test Plan:
CircleCI tests updated so that a couple of them use folly.

Most internal unit & stress/crash tests updated to use Meta-internal latest folly.
(Note: they should probably use buck but they currently use Makefile.)

Example performance improvement: when filter partitions are pinned in cache,
they are tracked by PartitionedFilterBlockReader::filter_map_ and we can build
a test that exercises that heavily. Build DB with

```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -benchmarks=fillrandom -num=10000000 -disable_wal=1 -write_buffer_size=30000000 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -partition_index_and_filters
```

and test with (simultaneous runs with & without folly, ~20 times each to see
convergence)

```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench_folly -readonly -use_existing_db -benchmarks=readrandom -num=10000000 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -partition_index_and_filters -duration=40 -pin_l0_filter_and_index_blocks_in_cache
```

Average ops/s no folly: 26229.2
Average ops/s with folly: 26853.3 (+2.4%)

1eee99fc8c Fix usage of USE_RTTI flag in CMakeLists. (#9760)
Summary:
By default, rocksdb release compiles with `-fno-rtti`. This causes issues when linking with other code that requires RTTI. Documentation indicate that setting the environment variable `USE_RTTI=1` when compiling rocksdb can override this behavior so that `-fno-rtti` is not used (http://rocksdb.org/blog/2017/09/28/rocksdb-5-8-released.html). However, this environment flag had no effect due to a bug in how `CMakeLists.txt` refers to `USE_RTTI`. This PR fixes this issue.

Now, running `USE_RTTI=1 cmake <......>` is correctly recognized by cmake, and causes `ROCKSDB_USE_RTTI `to be defined and `-fno-rtti` not to be issued for release builds. Behavior when USE_RTTI=0 or USE_RTTI is not provided is unchanged.

ae82d91492 Remove corrupted WAL files in kPointRecoveryMode with avoid_flush_duing_recovery set true (#9634)
Summary:
1) In case of non-TransactionDB and avoid_flush_during_recovery = true, RocksDB won't
flush the data from WAL to L0 for all column families if possible. As a
result, not all column families can increase their log_numbers, and
min_log_number_to_keep won't change.
2) For transaction DB (.allow_2pc), even with the flush, there may be old WAL files that it must not delete because they can contain data of uncommitted transactions and min_log_number_to_keep won't change.

If we persist a new MANIFEST with
advanced log_numbers for some column families, then during a second
crash after persisting the MANIFEST, RocksDB will see some column
families' log_numbers larger than the corrupted wal, and the "column family inconsistency" error will be hit, causing recovery to fail.

As a solution,
1. the corrupted WALs whose numbers are larger than the
corrupted wal and smaller than the new WAL will be moved to archive folder.
2. Currently, RocksDB DB::Open() may creates and writes to two new MANIFEST files even before recovery succeeds. This PR buffers the edits in a structure and writes to a new MANIFEST after recovery is successful

f241d082b6 Prevent double caching in the compressed secondary cache (#9747)
Summary:
###  **Summary:**
When both LRU Cache and CompressedSecondaryCache are configured together, there possibly are some data blocks double cached.

**Changes include:**
1. Update IS_PROMOTED to IS_IN_SECONDARY_CACHE to prevent confusions.
2. This PR updates SecondaryCacheResultHandle and use IsErasedFromSecondaryCache to determine whether the handle is erased in the secondary cache. Then, the caller can determine whether to SetIsInSecondaryCache().
3. Rename LRUSecondaryCache to CompressedSecondaryCache.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9747

Test Plan:
**Test Scripts:**
1. Populate a DB. The on disk footprint is 482 MB. The data is set to be 50% compressible, so the total decompressed size is expected to be 964 MB.
./db_bench --benchmarks=fillrandom --num=10000000 -db=/db_bench_1

2. overwrite it to a stable state:
./db_bench --benchmarks=overwrite,stats --num=10000000 -use_existing_db -duration=10 --benchmark_write_rate_limit=2000000 -db=/db_bench_1

4. Run read tests with diffeernt cache setting:

7ea26abb8b Fix reseting of async_read_in_progress_ variable in FilePrefetchBuffer to call Poll API (#9815)
Summary:
Currently RocksDB reset async_read_in_progress_ in callback
due to which underlying filesystem relying on Poll API won't be called
leading to stale memory access.
In order to fix it, async_read_in_progress_ will be reset after Poll API
is called to make sure underlying file_system waiting on Poll can clear
its state or take appropriate action.

e03f8a0c12 L0 Subcompaction to trim input files (#9802)
Summary:
When sub compaction is decided for L0->L1 compaction, most of the cases, all L0 files will be involved in all sub compactions. However, it is not always the case. When files are generally (but not strictly) inserted in sequential order, there can be a subset of L0 files invovled. Yet RocksDB always open all those L0 files, and build an iterator, read many of the files' first of last block with expensive readahead. We trim some input files to reduce overhead a little bit.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9802

Test Plan: Add a unit test to cover this case and manually validate the behavior while running the test.

8ce7cea93f Tests for filter compatibility (#9773)
Summary:
This change adds two unit tests that would each catch the
regression fixed in https://github.com/facebook/rocksdb/issues/9736

* TableMetaIndexKeys - detects any churn in metaindex block keys
generated by SST files using standard db_test_util configurations.
* BloomFilterCompatibility - this detects if any common built-in
FilterPolicy configurations fail to read filters generated by another.
(The regression bug caused NewRibbonFilterPolicy not to read filters
from NewBloomFilterPolicy and vice-versa.) This replaces some previous
tests that didn't really appear to be testing much of anything except
basic data correctness, which doesn't tell you a filter is being used.

Light refactoring in meta_blocks.cc/h to support inspecting metaindex
keys.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9773

Test Plan:
this is the test. Verified that 7.0.2 fails both tests and 7.0.3 passes.
With backporting for intentional API changes in 7.0, 6.29 also passes.

49623f9c8e Account memory of big memory users in BlockBasedTable in global memory limit (#9748)
Summary:
**Context:**
Through heap profiling, we discovered that `BlockBasedTableReader` objects can accumulate and lead to high memory usage (e.g, `max_open_file = -1`). These memories are currently not saved, not tracked, not constrained and not cache evict-able. As a first step to improve this, similar to https://github.com/facebook/rocksdb/pull/8428,  this PR is to track an estimate of `BlockBasedTableReader` object's memory in block cache and fail future creation if the memory usage exceeds the available space of cache at the time of creation.

**Summary:**
- Approximate big memory users  (`BlockBasedTable::Rep` and `TableProperties` )' memory usage in addition to the existing estimated ones (filter block/index block/un-compression dictionary)
- Charge all of these memory usages to block cache on `BlockBasedTable::Open()` and release them on `~BlockBasedTable()` as there is no memory usage fluctuation of concern in between
- Refactor on CacheReservationManager (and its call-sites) to add concurrent support for BlockBasedTable  used in this PR.

3ae9c5309b Remove explicit padding from CacheAlignedInstrumentedMutex (#9809)
Summary:
Fixes https://github.com/facebook/rocksdb/issues/9779.

The padding at the end of a struct is added implicitly according to the
sizeof spec: "When applied to a class, the result is the
number of bytes in an object of that class including any padding
required for placing objects of that type in an array"
(https://eel.is/c++draft/expr.sizeof#2.sentence-2). We should drop the
explicit padding since it assumed support for zero-length arrays, which
is non-standard.

60ceb8d0e2 rename property "kIsFileDeletionsEnabled" to "kIsFileDeletionsDisabled" (#9791)
Summary:
The name of this property "kIsFileDeletionsEnabled" is very, very easy to misunderstand.

I think 0 represents false (i.e. disabled) and non-0 means true (enabled), and this property is just the opposite.

I modified the name of this property, and as few other positions as possible, so that the final meaning remains the same, but the name of this property is more common sense.
