Peter Dillinger b515a5db3f Replace ScopedArenaIterator with ScopedArenaPtr<InternalIterator> (#12470)
Summary:
ScopedArenaIterator is not an iterator. It is a pointer wrapper. And we don't need a custom implemented pointer wrapper when std::unique_ptr can be instantiated with what we want.

So this adds ScopedArenaPtr<T> to replace those uses.

Andrew Kryczka bf98dcf9a8 Fix kBlockCacheTier read when merge-chain base value is in a blob file (#12462)
Summary:
The original goal is to propagate failures from `GetContext::SaveValue()` -> `GetContext::GetBlobValue()` -> `BlobFetcher::FetchBlob()` up to the user. This call sequence happens when a merge chain ends with a base value in a blob file.

There's also fixes for bugs encountered along the way where non-ok statuses were ignored/overwritten, and a bit of plumbing work for functions that had no capability to return a status.

anand76 63a105a481 Enable recycle_log_file_num option for point in time recovery (#12403)
Summary:
This option was previously disabled due to a bug in the recovery logic. The recovery code in `DBImpl::RecoverLogFiles` couldn't tell if an EoF reported by the log reader was really an EoF or a possible corruption that made a record look like an old log record. To fix this, the log reader now explicitly reports when it encounters what looks like an old record. The recovery code treats it as a possible corruption, and uses the next sequence number in the WAL to determine if it should continue replaying the WAL.

This PR also fixes a couple of bugs that log file recycling exposed in the backup and checkpoint path.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12403

Test Plan:
1. Add new unit tests to verify behavior upon corruption
2. Re-enable disabled tests for verifying recycling behavior

Yu Zhang 13e1c32a18 Follow ups for TimedPut and write time property (#12455)
Summary:
This PR contains a few follow ups from https://github.com/facebook/rocksdb/issues/12419 and https://github.com/facebook/rocksdb/issues/12428 including:

1) Handle a special case for `WriteBatch::TimedPut`. When the user specified write time is `std::numeric_limits<uint64_t>::max()`, it's not treated as an error, but it instead creates and writes a regular `Put` entry.

2) Update the `InternalIterator::write_unix_time` APIs to handle `kTypeValuePreferredSeqno` entries.

3) FlushJob is updated to use the seqno to time mapping copy in `SuperVersion`. FlushJob currently copy the DB's seqno to time mapping while holding db mutex and only copies the part of interest, a.k.a, the part that only goes back to the earliest sequence number of the to-be-flushed memtables. While updating FlushJob to use the mapping copy in `SuperVersion`, it's given access to the full mapping to help cover the need to convert `kTypeValuePreferredSeqno`'s write time to preferred seqno as much as possible.

Test plans:
Added unit tests

Kshitij Wadhwa 4ce1dc930c don't run ZSTD_TrainDictionary in BlockBasedTableBuilder if there isn't compression needed (#12453)
Summary:
fixes https://github.com/facebook/rocksdb/issues/12409

### Issue

ZSTD_TrainDictionary [[link](a53ed91691/table/block_based/block_based_table_builder.cc (L1894))] runs for SSTFileWriter::Finish even when bottommost_compression option is set to kNoCompression. This reduces throughput for SstFileWriter::Finish

We construct rocksdb options using ZSTD compression for levels including 2 and above. For levels 0 and 1, we set it to kNoCompression. We also set zstd_max_train_bytes to a non-zero positive value (which is applicable for levels with ZSTD compression enabled). These options are used for the database and also passed to SstFileWriter for creating sst files to be later added to that database. Since the BlockBasedTableBuilder::Finish [[link](a53ed91691/table/block_based/block_based_table_builder.cc (L1892))] only checks for zstd_max_train_bytes to be non-zero positive value, it runs ZSTD_TrainDictionary even when it shouldn't since SSTFileWriter is operating at bottommost level

### Fix

If compression_type is set to kNoCompression, then don't run ZSTD_TrainDictionary and dictionary building

### Testing

I see we have tests for sst file writer with compression type set/unset. Let me know if it isn't covered and I can extend

Hui Xiao 2443ebf810 Don't write to WAL after previous WAL write error (#12448)
Summary:
**Context/Summary:**
WAL write can continue onto the the WAL file that has encountered error and thus crash at 3f5bd46a07/file/writable_file_writer.cc (L67) in below scenario:
<img width="698" alt="Screenshot 2024-03-15 at 1 52 45 PM" src="https://github.com/facebook/rocksdb/assets/83968999/cd631ef2-c87c-4926-91ab-a0dc10f1eb14">

Note that GetLiveFilesStorageInfo() can happen concurrently with PUT() for the non-WAL-write part where db lock isn't held

This PR added an error check in LogWriter layer to prevent thread 2 from starting to write WAL after thread 1's write error.

Jay Huh db1dea22b1 MultiCfIterator Implementations (#12422)
Summary:
This PR continues https://github.com/facebook/rocksdb/issues/12153 by implementing the missing `Iterator` APIs - `Seek()`, `SeekForPrev()`, `SeekToLast()`, and `Prev`. A MaxHeap Implementation has been added to handle the reverse direction.

The current implementation does not include upper/lower bounds yet. These will be added in subsequent PRs. The API is still marked as under construction and will be lifted after being added to the stress test.

Please note that changing the iterator direction in the middle of iteration is expensive, as it requires seeking the element in each iterator again in the opposite direction and rebuilding the heap along the way. The first `Next()` after `SeekForPrev()` requires changing the direction under the current implementation. We may optimize this in later PRs.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12422

Test Plan: The `multi_cf_iterator_test` has been extended to cover the API implementations.

Summary:
with https://github.com/facebook/rocksdb/issues/12414 enabling `ReadOptions::pin_data`, this bug surfaced as corrupted per key-value checksum during crash test. `saved_key_.GetUserKey()` could be pinned user key, so DBIter should not overwrite it.

In one case, it only surfaces when iterator skips many keys of the same user key. To stress that code path, this PR also added `max_sequential_skip_in_iterations` to crash test.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12451

Test Plan:
- Set ReadOptions::pin_data to true, the bug can be reproed quickly with `./db_stress --persist_user_defined_timestamps=1 --user_timestamp_size=8 --writepercent=35 --delpercent=4 --delrangepercent=1 --iterpercent=20 --nooverwritepercent=1 --prefix_size=8 --prefixpercent=10 --readpercent=30 --memtable_protection_bytes_per_key=8 --block_protection_bytes_per_key=2 --clear_column_family_one_in=0`.
    - Set max_sequential_skip_in_iterations to 1 for the other occurrence of the bug.

Yu Zhang f2546b6623 Support returning write unix time in iterator property (#12428)
Summary:
This PR adds support to return data's approximate unix write time in the iterator property API. The general implementation is:
1) If the entry comes from a SST file, the sequence number to time mapping recorded in that file's table properties will be used to deduce the entry's write time from its sequence number. If no such recording is available, `std::numeric_limits<uint64_t>::max()` is returned to indicate the write time is unknown except if the entry's sequence number is zero, in which case, 0 is returned. This also means that even if `preclude_last_level_data_seconds` and `preserve_internal_time_seconds` can be toggled off between DB reopens, as long as the SST file's table property has the mapping available, the entry's write time can be deduced and returned.

2) If the entry comes from memtable, we will use the DB's sequence number to write time mapping to do similar things. A copy of the DB's seqno to write time mapping is kept in SuperVersion to allow iterators to have lock free access. This also means a new `SuperVersion` is installed each time DB's seqno to time mapping updates, which is originally proposed by Peter in  https://github.com/facebook/rocksdb/issues/11928 . Similarly, if the feature is not enabled, `std::numeric_limits<uint64_t>::max()` is returned to indicate the write time is unknown.

Needed follow up:
1) The write time for `kTypeValuePreferredSeqno` should be special cased, where it's already specified by the user, so we can directly return it.

2) Flush job can be updated to use DB's seqno to time mapping copy in the SuperVersion.

3) Handle the case when `TimedPut` is called with a write time that is `std::numeric_limits<uint64_t>::max()`. We can make it a regular `Put`.

Andrew Kryczka 3f5bd46a07 Add `ContinueCallback` to `GetMergeOperands()` (#12438)
Summary:
The use case is similar to `MergeOperator::ShouldMerge()` for `Get()`: preventing reads into LSM components for merge operands that are of no interest to the user. `MergeOperator::ShouldMerge()` cannot be reused here because:

- Its name does not make sense in the context of `GetMergeOperands()` since `GetMergeOperands()` never invokes merge
- The callback is part of the `MergeOperator`, but an option specific to the read operation makes more sense to me

If there are any ideas for an API design that covers both `MergeOperator::ShouldMerge()`'s use cases and `GetMergeOperandsOptions::continue_cb`'s use cases, that would be ideal, but for now this is what I came up with.

Yu Zhang 1104eaa35e Add initial support for TimedPut API (#12419)
Summary:
This PR adds support for `TimedPut` API. We introduced a new type `kTypeValuePreferredSeqno` for entries added to the DB via the `TimedPut` API.

The life cycle of such an entry on the write/flush/compaction paths are:

1) It is initially added to memtable as:
`<user_key, seq, kTypeValuePreferredSeqno>: {value, write_unix_time}`

2) When it's flushed to L0 sst files, it's converted to:
`<user_key, seq, kTypeValuePreferredSeqno>: {value, preferred_seqno}`
 when we have easy access to the seqno to time mapping.

3) During compaction, if certain conditions are met, we swap in the `preferred_seqno` and the entry will become:
`<user_key, preferred_seqno, kTypeValue>: value`. This step helps fast track these entries to the cold tier if they are eligible after the sequence number swap.

On the read path:
A `kTypeValuePreferredSeqno` entry acts the same as a `kTypeValue` entry, the unix_write_time/preferred seqno part packed in value is completely ignored.

Needed follow ups:
1) The seqno to time mapping accessible in flush needs to be extended to cover the `write_unix_time` for possible `kTypeValuePreferredSeqno` entries. This also means we need to track these `write_unix_time` in memtable.

2) Compaction filter support for the new `kTypeValuePreferredSeqno` type for feature parity with other `kTypeValue` and equivalent types.

3) Stress test coverage for the feature

Summary:
**Context/Summary:**
Previously manual compaction stress test failures won't terminate stress test. https://github.com/facebook/rocksdb/pull/12414 made more manual compaction failures terminate the stress test for signal boosting. A downside to that PR: some tolerable manual compaction stress test failures also unnecessarily terminate stress test.

Ideally we should exclude exactly those tolerable errors (left as a TODO) from being able to terminate. For now we approximate those errors by Aborted(), InvalidArgument(), NotSupported() etc. It's still an improvement to pre-https://github.com/facebook/rocksdb/pull/12414 situation.

Peter Dillinger dd24bda137 Fix windows build and CI (#12426)
Summary:
Issue https://github.com/facebook/rocksdb/issues/12421 describes a regression in the migration from CircleCI to GitHub Actions in which failing build steps no longer fail Windows CI jobs. In GHA with pwsh (new preferred powershell command), only the last non-builtin command (or something like that) affects the overall success/failure result, and failures in external commands do not exit the script, even with `$ErrorActionPreference = 'Stop'` and `$PSNativeCommandErrorActionPreference = $true`. Switching to `powershell` causes some obscure failure (not seen in CircleCI) about the `-Lo` option to `curl`.

Here we work around this using the only reasonable-but-ugly way known: explicitly check the result after every non-trivial build step. This leaves us highly susceptible to future regressions with unchecked build steps in the future, but a clean solution is not known.

This change also fixes the build errors that were allowed to creep in because of the CI regression. Also decreased the unnecessarily long running time of DBWriteTest.WriteThreadWaitNanosCounter.

For background, this problem explicitly contradicts GitHub's documentation, and GitHub has known about the problem for more than a year, with no evidence of caring or intending to fix. https://github.com/actions/runner-images/issues/6668 Somehow CircleCI doesn't have this problem. And even though cmd.exe and powershell have been perpetuating DOS-isms for decades, they still seem to be a somewhat active "hot mess" when it comes to sensible, consistent, and documented behavior.

Fixes https://github.com/facebook/rocksdb/issues/12421

The PR adds a wide-column point lookup API `GetEntityFromBatch` to `WriteBatchWithIndex`. Similarly to APIs like `DB::GetEntity`, this new API returns wide-column entities as-is, and wraps plain values in an entity with a single column (the anonymous default column). Also, similarly to `WriteBatchWithIndex::GetFromBatch`, it only reads data from the batch itself.

- Run `python3 tools/db_crashtest.py --simple blackbox --compact_files_one_in=1 --compact_range_one_in=1 --read_fault_one_in=1 --write_fault_one_in=1 --interval=50` for a while to ensure the bonus change does not result in trivial crash/termination of stress test

Pavel Ferencz 122510dc09 Workaround for an issue with Cmake builds that happens when cross-compiling using Cmake on macOS x86_64 CPUs with target CPU arm64 (#12240)
Summary:
This is a temporary workaround for Cmake bug that only sets the correct CMAKE_SYSTEM_PROCESSOR for cross-compilation when target CMAKE_SYSTEM_NAME differs from CMAKE_HOST_NAME:
https://gitlab.kitware.com/cmake/cmake/-/issues/25640

Fix cross-compilation on macOS x86_64 CPUs with target CPU arm64 by manually setting CMAKE_SYSTEM_PROCESSOR to the cross-compilation target whenever CMAKE_SYSTEM_PROCESSOR doesn't match CMAKE_OSX_ARCHITECTURES after project() call. This is probably a Cmake bug that happens on macOS.
Closes https://github.com/facebook/rocksdb/issues/12239

The issue happens when RocksDB is built using the follwoing command:
cmake -G "Unix Makefiles" -DCMAKE_SYSTEM_PROCESSOR=arm64 ..
The build itself succeeds, but because Cmake wrongly sets CMAKE_SYSTEM_PROCESSOR to x86_64 instead of arm64 and causes crc32c_arm64.cc not to be compiled.
This in turn makes the project fails any linking with RocksDB:

```
Undefined symbols for architecture arm64:
"crc32c_arm64(unsigned int, unsigned char const*, unsigned long)", referenced from:
rocksdb::crc32c::ExtendARMImpl(unsigned int, char const*, unsigned long) in librocksdb.a(crc32c.cc.o)
```

Alan Paxton d9a441113e JNI get_helper code sharing / multiGet() use efficient batch C++ support (#12344)
Summary:
Implement RAII-based helpers for JNIGet() and multiGet()

Replace JNI C++ helpers `rocksdb_get_helper, rocksdb_get_helper_direct`, `multi_get_helper`, `multi_get_helper_direct`, `multi_get_helper_release_keys`, `txn_get_helper`, and `txn_multi_get_helper`.

The model is to entirely do away with a single helper, instead a number of utility methods allow each separate
JNI `Get()` and `MultiGet()` method to organise their parameters efficiently, then call the underlying C++ `db->Get()`,
`db->MultiGet()`, `txn->Get()`, or `txn->MultiGet()` method itself, and use further utilities to retrieve results.

Roughly speaking:

* get keys into C++ form
* Call C++ Get()
* get results and status into Java form

We achieve a useful performance gain as part of this work; by using the updated C++ multiGet we immediately pick up its performance gains (batch improvements to multiGet C++ were previously implemented, but not until now used by Java/JNI). multiGetBB already uses the batched C++ multiGet(), and all other benchmarks show consistent improvement after the changes:

Summary:
Add `SstFileReader::VerifyNumEntries()` for this purpose. I added the same functionality to `sst_dump` in https://github.com/facebook/rocksdb/issues/12322. Since sst_file_reader.h is exposed to users while sst_dump.h is not, it seems more appropriate to add SST files related APIs here.

Alan Paxton c4d37da826 Java API - Fix handling of CF handles in DB subclasses (#12417)
Summary:
The most general `open()` method for each of RocksDB, TtlDB, OptimisticTransactionDB and TransactionDB should
- ensure the default CF is supplied in the list of descriptors
- cache the default CF handle
- store open CF handles for automatic close on DB close
The `close()` method in each of these DB subclasses should `close()` all the owned CF handles.

I can’t find a cleaner way to build some generalised open/close that does this for all DB subclasses, so it exists as cut and paste with variations in the 4 different DB subclasses.

Added some slightly paranoid testing that CF handles explicitly referred to as default in a list of CF handles in the general open methods, and the simple open that doesn’t supply a CF, end up reading and writing to the same CF. Prompted by the fact that this code is a bit opaque; the first returned handle is the DB.

As part of this, fix the bug where the Java side of `OptimisticsTransactionDB` was not setting up default column family; this was visible when setting up an iterator; add a test to validate that the iterator is OK. A single Java reference to the default column family was not being created in the OptimisticsTransactionDB RocksDB subclass; it should be created in all subclasses. The same problem had previously been fixed for TtlDB.

This is almost certainly caused by the sync point callback happening on asynchronous file deletion in the DB while the end of the test is reached and the destruction of the `DBTestXactLogIterator` has reached `DBTestBase::~DBTestBase()`. Either closing the DB or disabling sync points before the end of the test should suffice to fix, and we'll do both. And assert that the sync point callback is actually hit each time.

anand76 179afd5bef Add a FS flag to detect and correct corruption (#12408)
Summary:
Add a flag in `IOOptions` to request the file system to make best efforts to detect data corruption and reconstruct the data if possible. This will be used by RocksDB to retry a read if the previous read returns corrupt data (checksum mismatch). Add a new op to `FSSupportedOps` that, if supported, will trigger this behavior in RocksDB.

Yu Zhang 210c8df820 Use do_validate flag to control timestamp based validation in WriteCommittedTxn::GetForUpdate (#12369)
Summary:
When PR https://github.com/facebook/rocksdb/issues/9629 introduced user-defined timestamp support for `WriteCommittedTxn`, it adds this usage mandate for API `GetForUpdate` when UDT is enabled. The `do_validate` flag has to be true, and user should have already called `Transaction::SetReadTimestampForValidation` to set a read timestamp for validation. The rationale behind this mandate is this:
1) with do_vaildate = true, `GetForUpdate` could verify this relationships: let's denote the user-defined timestamp in db for the key as  `Ts_db` and the read timestamp user set via `Transaction::SetReadTimestampForValidation` as `Ts_read`. UDT based validation will only pass if `Ts_db <= Ts_read`.
5950907a82/utilities/transactions/transaction_util.cc (L141)

2)  Let's denote the committed timestamp set via `Transaction::SetCommitTimestamp` to be `Ts_cmt`. Later `WriteCommitedTxn::Commit` would only pass if this condition is met: `Ts_read < Ts_cmt`. 5950907a82/utilities/transactions/pessimistic_transaction.cc (L431)

Together these two checks can ensure `Ts_db < Ts_cmt` to meet the user-defined timestamp invariant that newer timestamp should have newer sequence number.

The `do_validate` flag was originally intended to make snapshot based validation optional. If it's true, `GetForUpdate` checks no entry is written after the snapshot. If it's false, it will skip this snapshot based validation. In this PR, we are making the UDT based validation configurable too based on this flag instead of mandating it for below reasons: 1) in some cases the users themselves can enforce aformentioned invariant on their side independently, without RocksDB help, for example, if they are managing a monotonically increasing timestamp, and their transactions are only committed in a single thread. So they don't need this UDT based validation and wants to skip it, 2) It also could be expensive or not practical for users to come up with such a read timestamp that is exactly in between their commit timestamp and the db's timestamp. For example, in aformentioned case where a monotonically increasing timestamp is managed, the users would need to access this timestamp both for setting the read timestamp and for setting the commit timestamp. So it's preferable to skip this check too.

Andrew Kryczka 27a2473668 Best-effort recovery support for atomic flush (#12406)
Summary:
This PR updates `VersionEditHandlerPointInTime` to recover all or none of the updates in an AtomicGroup. This makes best-effort recovery properly handle atomic flushes during recovery, so the features are now allowed to both be enabled at once.

The new logic requires that AtomicGroups do not contain column family additions or removals. AtomicGroups are currently written for atomic flush, which does not include such edits.

Column family additions or removals are recovered independently of AtomicGroups. The new logic needs to be aware of removal, though, so that a dropped CF does not prevent completion of an AtomicGroup recovery.

The new logic treats each AtomicGroup as if it contains updates for all existing column families, even though it is possible to create AtomicGroups that only affect a subset of column families. This simplifies the logic at the expense of recovering less data in certain edge case scenarios.

The usage of `MaybeCreateVersion()` is pretty tricky. The goal is to create a barrier at the start of an AtomicGroup such that all valid states up to that point will be applied to `versions_`. Here is a summary.

- `MaybeCreateVersion(..., false)` creates a `Version` on a negative edge trigger (transition from valid to invalid). It was  previously called when applying each update. Now, it is only called when applying non-AtomicGroup updates.
- `MaybeCreateVersion(..., true)` creates a `Version` on a positive level trigger (valid state). It was previously called only at the end of iteration. Now, it is additionally called before processing an AtomicGroup.

Peter Dillinger a53ed91691 Fix/improve temperature handling for file ingestion (#12402)
Summary:
Partly following up on leftovers from https://github.com/facebook/rocksdb/issues/12388

In terms of public API:
* Make it clear that IngestExternalFileArg::file_temperature is just a hint for opening the existing file, though it was previously used for both copy-from temp hint and copy-to temp, which was bizarre.
* Specify how IngestExternalFile assigns temperature to file ingested into DB. (See details in comments.) This approach is not perfect in terms of matching how the DB assigns temperatures, but was the simplest way to get close. The key complication for matching DB temperature assignments is that ingestion files are copied (to a destination temp) before their target level is determined (in general).
* Add a temperature option to SstFileWriter::Open so that files intended for ingestion can be initially written to a chosen temperature.
* Note that "fail_if_not_bottommost_level" is obsolete/confusing use of "bottommost"

In terms of the implementation, there was a similar bit of oddness with the internal CopyFile API, which only took one temperature, ambiguously applicable to the source, destination, or both. This is also fixed.

Eventual suggested follow-up:
* Before copying files for ingestion, determine a tentative level assignment to use for destination temperature, and keep that even if final level assignment happens to be different at commit time (rare).
* More temperature handling for CreateColumnFamilyWithImport and Checkpoints.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12402

Test Plan:
Deeply revamped
ExternalSSTFileBasicTest.IngestWithTemperature to test the new changes. Previously this test was insufficient because it was only looking at temperatures according to the DB manifest. Incorporating FileTemperatureTestFS allows us to also test the temperatures in the storage layer.

Used macros instead of functions for better tracing to critical source location on test failures.

Some enhancements to FileTemperatureTestFS in the process of developing the revamped test.

Jay Huh 3412195367 Introduce MultiCfIterator (#12153)
Summary:
This PR introduces a new implementation of `Iterator` via a new public API called `NewMultiCfIterator()`. The new API takes a vector of column family handles to build a cross-column-family iterator, which internally maintains multiple `DBIter`s as child iterators from a consistent database state. When a key exists in multiple column families, the iterator selects the value (and wide columns) from the first column family containing the key, following the order provided in the `column_families` parameter. Similar to the merging iterator, a min heap is used to iterate across the child iterators. Backward iteration and direction change functionalities will be implemented in future PRs.

The comparator used to compare keys across different column families will be derived from the iterator of the first column family specified in `column_families`. This comparator will be checked against the comparators from all other column families that the iterator will traverse. If there's a mismatch with any of the comparators, the initialization of the iterator will fail.

Please note that this PR is not enough for users to start using `MultiCfIterator`. The `MultiCfIterator` and related APIs are still marked as "**DO NOT USE - UNDER CONSTRUCTION**". This PR is just the first of many PRs that will follow soon.

This PR includes the following:
- Introduction and partial implementation of the `MultiCfIterator`, which implements the generic `Iterator` interface. The implementation includes the construction of the iterator, `SeekToFirst()`, `Next()`, `Valid()`, `key()`, `value()`, and `columns()`.
- Unit tests to verify iteration across multiple column families in two distinct scenarios: (1) keys are unique across all column families, and (2) the same keys exist in multiple column families.

jsteemann 3fff57fa6a fix linking without thread status support (#12400)
Summary:
When compiling with `-DNROCKSDB_THREAD_STATUS`, some functions in ThreadStatusUtil are declared but their definition is missing. Their definitions are only compiled when not defining `NROCKSDB_THREAD_STATUS`. This causes problems on linking, when the linker cannot find the definitions of

- ThreadStatusUtil::GetThreadOperation
- ThreadStatusUtil::SetEnableTracking

This PR fixes it by adding stubs for these functions in case `NROCKSDB_THREAD_STATUS` is defined.

yuzhangyu@fb.com 1cfdece85d Run internal cpp modernizer on RocksDB repo (#12398)
Summary:
When internal cpp modernizer attempts to format rocksdb code, it will replace macro `ROCKSDB_NAMESPACE`  with its default definition `rocksdb` when collapsing nested namespace. We filed a feedback for the tool T180254030 and the team filed a bug for this: https://github.com/llvm/llvm-project/issues/83452. At the same time, they suggested us to run the modernizer tool ourselves so future auto codemod attempts will be smaller. This diff contains:

Running
`xplat/scripts/codemod_service/cpp_modernizer.sh`
in fbcode/internal_repo_rocksdb/repo (excluding some directories in utilities/transactions/lock/range/range_tree/lib that has a non meta copyright comment)
without swapping out the namespace macro `ROCKSDB_NAMESPACE`

Followed by RocksDB's own
`make format`

Jay Huh c00c16855d Access DBImpl* and CFD* by CFHImpl* in Iterators (#12395)
Summary:
In the current implementation of iterators, `DBImpl*` and `ColumnFamilyData*` are held in `DBIter` and `ArenaWrappedDBIter` for two purposes: tracing and Refresh() API. With the introduction of a new iterator called MultiCfIterator in PR https://github.com/facebook/rocksdb/issues/12153 , which is a cross-column-family iterator that maintains multiple DBIters as child iterators from a consistent database state, we need to make some changes to the existing implementation. The new iterator will still be exposed through the generic Iterator interface with an additional capability to return AttributeGroups (via `attribute_groups()`) which is a list of wide columns grouped by column family. For more information about AttributeGroup, please refer to previous PRs:  https://github.com/facebook/rocksdb/issues/11925 #11943, and https://github.com/facebook/rocksdb/issues/11977.

To be able to return AttributeGroup in the default single CF iterator created, access to `ColumnFamilyHandle*` within `DBIter` is necessary. However, this is not currently available in `DBIter`. Since `DBImpl*` and `ColumnFamilyData*` can be easily accessed via `ColumnFamilyHandleImpl*`, we have decided to replace the pointers to `ColumnFamilyData` and `DBImpl` in `DBIter` with a pointer to `ColumnFamilyHandleImpl`.
