Temporally disable log recycle with testing GetLiveFilesStorageInfo() (#12868)
Summary: **Context/Summary:** We recently discovered a case where `GetLiveFilesStorageInfo()` failed when `Options::recycle_log_file_num` > 0. Before fixing the incompatibility, we disable these combination in stress test.

Deflake ThreadStatus related unit tests (#12858)
Summary:
Unit tests `DBTest.ThreadStatusFlush` and `DBTestWithParam.ThreadStatusSingleCompaction` have been flaky and fail with error message
```
[ RUN ] DBTest.ThreadStatusFlush
op_count: 0, expected_count 1
thread id: 718113, thread status: , cf_name

Value of: VerifyOperationCount(env_, ThreadStatus::OP_FLUSH, 1)
Actual: false
Expected: true
[ FAILED ] DBTest.ThreadStatusFlush (106 ms)
[ RUN ] DBTestWithParam/DBTestWithParam.ThreadStatusSingleCompaction/0
db/db_test.cc:4673: Failure
Expected equality of these values:
op_count
Which is: 0
expected_count
Which is: 1
[ FAILED ] DBTestWithParam/DBTestWithParam.ThreadStatusSingleCompaction/0, where GetParam() = (1, false)
```
One cause for this is that before flush/compaction finishes, we will go through `~WritableFileWriter()`, either for WAL or SST file, and temporarily set thread_operation to UNKNOWN. This UNKNOWN thread operation seem to be there for some stress test verification. This PR fixes these tests by setting the IOActivity in ~WritableFileWriter() for debug build.

Avoid SyncWAL if flushing during shutdown (#12853)
Summary: https://github.com/facebook/rocksdb/issues/12746 added calls to FlushWAL/SyncWAL in db_stress during reopen, in order to ensure persistence of unpersisted data and avoid false alarms due to lack of prefix recovery support in db_stress reopen. However, there's no need to flush/sync the WAL if avoid_flush_during_shutdown is false, as the WAL will not be needed during recovery. This allows file systems that don't support SyncWAL (not thread safe) to avoid the need by requesting flush during shutdown.

Fix race in multiops txn stress test (#12847)
Summary: `MultiOpsTxnsStressListener::OnCompactionCompleted()` access `db_` and can be called while db_ is being destroyed in ~StressTest(). This causes TSAN to complain about data race. This PR fixes this issue by calling db_->Close() first to stop all background work. Also moved the cleanup out of StressTest destructor to avoid race between the listener and ~StressTest().

Fix WAL corruption in stress test (#12834)
Summary: We are seeing WAL corruption in crash tests where wal_compression and recycled_wal are enabled. With wal_compression, we write a SetCompression record when creating a WAL, which can happen during DB open time. Our current stress test set up may write directly to the underlying WAL file during DB open, while writing to a buffer under TestFSWritableFile later for sync fault injection. This causes the last synced position to be inaccurately tracked in TestFSWritableFile and causes reads to return incorrect data. This PR removes the line that causes this mixture of WAL writes. Also updated TestFSWritableFile to avoid such a mixture of buffered and direct writes.

Decouple sync fault and write injection in FaultInjectionTestFS & fix tracing issue under WAL write error injection (#12797)
Summary:
**Context/Summary:**
After injecting write error to WAL, we started to see crash recovery verification failure in prefix recovery. That's because the current tracing implementation traces every write before it writes to WAL even when the WAL write can fail with write error injection. One consequence of that is the traced writes in trace files does not corresponding to write sequence sequence anymore e.g, it has more traced writes that the actual assigned sequence number to successful writes. Therefore

Tag FaultInjectionIOType::kRead for FaultInjectionTestFS new read file & fix unrelease snapshot (#12810)
Summary:
**Context/Summary:** It makes more sense to mark error injection during creation as read file as "kread" so we don't get confusing msg like below
```
stderr:
error : Get() returns IO error: injected metadata write error for key: 000000000000004F000000000000012B00000000000000EF.
Verification failed :(
```
Also an early return here

Fix not getting expected injected read error (#12793)
Summary: **Context/Summary:** https://github.com/facebook/rocksdb/pull/12713 accidentally removed the mechanism of ignoring injected read error on non-critical read path such as read from filter. IO failure in read from filter should not fail the read as we can always read from the actual file. Therefore error injection in filter read path does not need to lead to failure in Get() and crash test should allow that. Otherwise, we will get crash test error "Didn't get expected error from..."

Inject more errors to more files in stress test (#12713)
Summary: **Context:** We currently have partial error injection: - DB operation: all read, SST write - DB open: all read, SST write, all metadata write. This PR completes the error injection (with some limitations below): - DB operation & open: all read, all write, all metadata write, all metadata read **Summary:** - Inject retryable metadata read, metadata write error concerning directory (e.g, dir sync, ) or file metadata (e.g, name, size, file creation/deletion...) - Inject retryable errors to all major file types: random access file, sequential file, writable file - Allow db stress test operations to handle above injected errors gracefully without crashing - Change all error injection to thread-local implementation for easier disabling and enabling in the same thread. For example, we can control error handling thread to have no error injection. It's also cleaner in code. - Limitation: compared to before, we now don't have write fault injection for backup/restore CopyOrCreateFiles work threads since they use anonymous background threads as well as read injection for db open bg thread - Add a new flag to test error recovery without error injection so we can test the path where error recovery actually succeeds - Some Refactory & fix to db stress test framework (see PR review comments) - Fix some minor bugs surfaced (see PR review comments) - Limitation: had to disable backup restore with metadata read/write injection since it surfaces too many testing issues. Will add it back later to focus on surfacing actual code/internal bugs first.

Add experimental range filters to stress/crash test (#12769)
Summary: Implemented two key segment extractors that satisfy the "segment prefix property," one with variable segment widths and one with fixed. Used these to create a couple of named configs and versions that are randomly selected by the crash test. On the read side, the required table_filter is set up everywhere I found the stress test uses iterator_upper_bound. Writing filters on new SST files and applying filters on SST files to range queries are configured independently, to potentially help with isolating different sides of the functionality. Not yet implemented / possible follow-up: * Consider manipulating/skewing the query bounds to better exercise filters * Not yet using categories in the extractors * Not yet dynamically changing the filtering version Pull Request resolved: https://github.com/facebook/rocksdb/pull/12769 Test Plan: Some stress test trial runs, including with ASAN. Inserted some temporary probes to ensure code was being exercised (more or less) as intended.

Enable reading un-synced data in db stress test (#12752)

So it will surface as ``` Verification failed: VerifyChecksum failed: Corruption: file is too short (0 bytes) to be an sstable: /tmp/rocksdb_crashtest_blackbox4deg_c5e/000009.sst db_stress: db_stress_tool/db_stress_test_base.cc:518: void rocksdb::StressTest::ProcessStatus(rocksdb::SharedState*, std::string, const rocksdb::Status&, bool) const: Assertion `false' failed.

Fix manual WAL flush causing false-positive inconsistent values in TestBackupRestore() (#12758)

It never made it to WAL file without FlushWAL() t2: The same WAL got back-up and restored to restore DB. So the restore DB's WAL does not contain this Put() t3: The same WAL in the original DB got FlushWAL() so it got the Put() entry Querying k1 in original and restored DB will give different result and fail our consistency check in stress test. ``` Failure in a backup/restore operation with: Corruption: 0x000000000000000178 exists in original db but not in restore ``` This PR fixed it.

Support pro-actively erasing obsolete block cache entries (#12694)
Summary: Currently, when files become obsolete, the block cache entries associated with them just age out naturally. With pure LRU, this is not too bad, as once you "use" enough cache entries to (re-)fill the cache, you are guranteed to have purged the obsolete entries. However, HyperClockCache is a counting clock cache with a somewhat longer memory, so could be more negatively impacted by previously-hot cache entries becoming obsolete, and taking longer to age out than newer single-hit entries. Part of the reason we still have this natural aging-out is that there's almost no connection between block cache entries and the file they are associated with. Everything is hashed into the same pool(s) of entries with nothing like a secondary index based on file. Keeping track of such an index could be expensive. This change adds a new, mutable CF option `uncache_aggressiveness` for erasing obsolete block cache entries. The process can be speculative, lossy, or unproductive because not all potential block cache entries associated with files will be resident in memory, and attempting to remove them all could be wasted CPU time. Rather than a simple on/off switch, `uncache_aggressiveness` basically tells RocksDB how much CPU you're willing to burn trying to purge obsolete block cache entries. When such efforts are not sufficiently productive for a file, we stop and move on. The option is in ColumnFamilyOptions so that it is dynamically changeable for already-open files, and customizeable by CF. Note that this block cache removal happens as part of the process of purging obsolete files, which is often in a background thread (depending on `background_purge_on_iterator_cleanup` and `avoid_unnecessary_blocking_io` options) rather than along CPU critical paths. Notable auxiliary code details: * Possibly fixing some issues with trivial moves with `only_delete_metadata`: unnecessary TableCache::Evict in that case and missing from the ObsoleteFileInfo move operator. (Not able to reproduce an current failure.) * Remove suspicious TableCache::Erase() from VersionSet::AddObsoleteBlobFile() (TODO follow-up item) Marked EXPERIMENTAL until more thorough validation is complete. Direct stats of this functionality are omitted because they could be misleading. Block cache hit rate is a better indicator of benefit, and CPU profiling a better indicator of cost. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12694 Test Plan: * Unit tests added, including refactoring an existing test to make better use of parameterized tests. * Added to crash test. * Performance, sample command: ``` for I in `seq 1 10`; do for UA in 300; do for CT in lru_cache fixed_hyper_clock_cache auto_hyper_clock_cache; do rm -rf /dev/shm/test3; TEST_TMPDIR=/dev/shm/test3 /usr/bin/time ./db_bench -benchmarks=readwhilewriting -num=13000000 -read_random_exp_range=6 -write_buffer_size=10000000 -bloom_bits=10 -cache_type=$CT -cache_size=390000000 -cache_index_and_filter_blocks=1 -disable_wal=1 -duration=60 -statistics -uncache_aggressiveness=$UA 2>&1 | grep -E 'micros/op|rocksdb.block.cache.data.(hit|miss)|rocksdb.number.keys.(read|written)|maxresident' | awk '/rocksdb.block.cache.data.miss/ { miss = $4 } /rocksdb.block.cache.data.hit/ { hit = $4 } { print } END { print "hit rate = " ((hit * 1.0) / (miss + hit)) }' | tee -a results-$CT-$UA; done; done; done ``` Averaging 10 runs each case, block cache data block hit rates ``` lru_cache UA=0 -> hit rate = 0.327, ops/s = 87668, user CPU sec = 139.0 UA=300 -> hit rate = 0.336, ops/s = 87960, user CPU sec = 139.0 fixed_hyper_clock_cache UA=0 -> hit rate = 0.336, ops/s = 100069, user CPU sec = 139.9 UA=300 -> hit rate = 0.343, ops/s = 100104, user CPU sec = 140.2 auto_hyper_clock_cache UA=0 -> hit rate = 0.336, ops/s = 97580, user CPU sec = 140.5 UA=300 -> hit rate = 0.345, ops/s = 97972, user CPU sec = 139.8 ``` Conclusion: up to roughly 1 percentage point of improved block cache hit rate, likely leading to overall improved efficiency (because the foreground CPU cost of cache misses likely outweighs the background CPU cost of erasure, let alone I/O savings).

Fix Checkpoint hard link of inactive but unsynced WAL (#12731)
Summary: Background: there is one active WAL file but there can be several more WAL files in various states. Those other WALs are always in a "flushed" state but could be on the `logs_` list not yet fully synced. We currently allow any WAL that is not the active WAL to be hard-linked when creating a Checkpoint, as although it might still be open for write, we are not appending any more data to it. The problem is that a created Checkpoint is supposed to be fully synced on return of that function, and a hard-linked WAL in the state described above might not be fully synced. (Through some prudence in https://github.com/facebook/rocksdb/issues/10083, it would synced if using track_and_verify_wals_in_manifest=true.) The fix is a step toward a long term goal of removing the need to query the filesystem to determine WAL files and their state. (I consider it dubious any time we independently read from or query metadata from a file we have open for writing, as this makes us more susceptible to FileSystem deficiencies or races.) More specifically: * Detect which WALs might not be fully synced, according to our DBImpl metadata, and prevent hard linking those (with `trim_to_size=true` from `GetLiveFilesStorageInfo()`. And while we're at it, use our known flushed sizes for those WALs. * To avoid a race between that and GetSortedWalFiles(), track a maximum needed WAL number for the Checkpoint/GetLiveFilesStorageInfo. * Because of the level of consistency provided by those two, we no longer need to consider syncing as part of the FlushWAL in GetLiveFilesStorageInfo. (We determine the max WAL number consistent with the manifest file size, while holding DB mutex. Should make track_and_verify_wals_in_manifest happy.) This makes the premise of test PutRaceWithCheckpointTrackedWalSync obsolete (sync point callback no longer hit) so the test is removed, with crash test as backstop for related issues.

FaultInjectionTestFS read unsynced data by default (#12729)
Summary: In places (e.g. GetSortedWals()) RocksDB relies on querying the file size or even reading the contents of files currently open for writing, and as in POSIX semantics, expects to see the flushed size and contents regardless of what has been synced. FaultInjectionTestFS historically did not emulate this behavior, only showing synced data from such read operations. (Different from FaultInjectionTestEnv--sigh.) This change makes the "proper" behavior the default behavior, at least for GetFileSize and FSSequentialFile. However, this new functionality is disabled in db_stress because of undiagnosed, unresolved issues. Also removes unused and confusing field `pos_at_last_flush_` This change is needed to support testing a relevant bug fix (in a follow-up diff). Other suggested follow-up: * Fix db_stress not to rely on the old behavior, and fix a related FIXME in db_stress_test_base.cc in LockWAL testing. * Fill in some corner cases in the FileSystem API for reading unsynced data (see new TODO items). * Consider deprecating and removing Flush() API functions from FileSystem APIs. It is not clear to me that there is a supported scenario in which they do anything but confuse API users and developers. If there is a use for them, it doesn't appear to be tested. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12729 Test Plan: applies to all unit tests successfully, just updating the unit test from https://github.com/facebook/rocksdb/issues/12556 due to relying on the errant behavior.

Note that since the stress test generates wide-column structures which have the value returned by `GenerateValue` in the default column, this does not affect the results returned by the `MultiGet` API (unless we have a bug). The wide-column entity is generated according to the usual rules based on the value base and the `use_put_entity_one_in` flag. The entire entity structure will be validated by the upcoming stress test for `Transaction::MultiGetEntity`, where we also plan to leverage this logic.

Improve universal compaction sorted-run trigger (#12477)
Summary: Universal compaction currently uses `level0_file_num_compaction_trigger` for two purposes: 1. the trigger for checking if there is any compaction to do, and 2. the limit on the number of sorted runs. RocksDB will do compaction to keep the number of sorted runs no more than the value of this option. This can make the option inflexible. A value that is too small causes higher write amp: more compactions to reduce the number of sorted runs. A value that is too big delays potential compaction work and causes worse read performance. This PR introduce an option `CompactionOptionsUniversal::max_read_amp` for only the second purpose: to specify the hard limit on the number of sorted runs. For backward compatibility, `max_read_amp = -1` by default, which means to fallback to the current behavior. When `max_read_amp > 0`,`level0_file_num_compaction_trigger` will only serve as a trigger to find potential compaction. When `max_read_amp = 0`, RocksDB will auto-tune the limit on the number of sorted runs. The estimation is based on DB size, write_buffer_size and size_ratio, so it is adaptive to the size change of the DB. See more in `UniversalCompactionBuilder::PickCompaction()`. Alternatively, users now can configure `max_read_amp` to a very big value and keep `level0_file_num_compaction_trigger` small. This will allow `size_ratio` and `max_size_amplification_percent` to control the number of sorted runs. This essentially disables compactions with reason kUniversalSortedRunNum. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12477 Test Plan: * new unit test * existing unit test for default behavior * updated crash test with the new option * benchmark: * Create a DB that is roughly 24GB in the last level.

write amp. * case 1: small level0 trigger: `level0_file_num_compaction_trigger=5, max_read_amp=-1` * write-amp: 4.8 * case 2: auto-tune: `level0_file_num_compaction_trigger=5, max_read_amp=0` * write-amp: 3.6 * case 3: auto-tune with minimal trigger: `level0_file_num_compaction_trigger=1, max_read_amp=0` * write-amp: 3.8 * case 4: hard-code a good value for trigger: `level0_file_num_compaction_trigger=9` * write-amp: 2.8 ``` Case 1: ** Compaction Stats [default] ** Level Files Size Score Read(GB) Rn(GB) Rnp1(GB) Write(GB) Wnew(GB) Moved(GB) W-Amp Rd(MB/s)

Fix a couple of issues in the stress test for Transaction::MultiGet (#12696)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12696 Two fixes: 1) `Random::Uniform(n)` returns an integer from the interval [0, n - 1], so `Uniform(2)` returns 0 or 1, which means is that we have apparently never covered transactions with deletions in the test. (To prevent similar issues, the patch cleans this write logic up a bit using an `enum class` for the type of write.) 2) The keys passed in to `TestMultiGet` can have duplicates. What this boils down to is that we have to keep track of the latest expected values for read-your-own-writes on a per-key basis.

Add Transaction::PutEntity to the stress tests (#12688)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12688 As a first step of covering the wide-column transaction APIs, the patch adds `PutEntity` to the optimistic and pessimistic transaction stress tests (for the latter, only when the WriteCommitted policy is utilized). Other APIs and the multi-operation transaction test will be covered by subsequent PRs.

Disallow memtable flush and sst ingest while WAL is locked (#12652)
Summary: We recently noticed that some memtable flushed and file ingestions could proceed during LockWAL, in violation of its stated contract. (Note: we aren't 100% sure its actually needed by MySQL, but we want it to be in a clean state nonetheless.) Despite earlier skepticism that this could be done safely (https://github.com/facebook/rocksdb/issues/12666), I found a place to wait to wait for LockWAL to be cleared before allowing these operations to proceed: WaitForPendingWrites() Pull Request resolved: https://github.com/facebook/rocksdb/pull/12652 Test Plan: Added to unit tests. Extended how db_stress validates LockWAL and re-enabled combination of ingestion and LockWAL in crash test, in follow-up to https://github.com/facebook/rocksdb/issues/12642 Ran blackbox_crash_test for a long while with relevant features amplified. Suggested follow-up: fix FaultInjectionTestFS to report file sizes consistent with what the user has requested to be flushed.

Fix locking for `ColumnFamilyOptions::inplace_update_support` (#12624)
Summary: In `SaveValue()`, the read lock needs to be obtained before `VerifyEntryChecksum()` because the KV checksum verification reads the entire value metadata+data, which is all mutable when `ColumnFamilyOptions::inplace_update_support == true`. In `MemTable::Update()`, the write lock needs to be obtained before mutating the value metadata (changing the value size) because it can be read concurrently.

Clarify manual compaction and file ingestion behavior with FIFO compaction (#12618)
Summary:
For manual compaction, FIFO compaction will always skip key range overlapping checking with SST files. If CompactRange() is called with CompactionRangeOptions::change_level=true, a CF with FIFO compaction will now return Status::NotSupported.
For file ingestion, we will always ingest into L0. Previously, it's possible to ingest files into non-L0 levels with FIFO compaction.
These changes also help to fix [this](
