Initialize merge operator explicitly in PrepareOptionsForRestoredDB() (#12033)
Summary: We are seeing the following stress test failure: `Failure in DB::Get in backup/restore with: Invalid argument: merge_operator is not properly initialized. Verification failed: Backup/restore failed: Invalid argument: merge_operator is not properly initialized.`. The reason is likely that `GetColumnFamilyOptionsFromString()` does not set merge operator if it's a customized merge operator. Fixing it by initializing merge operator explicitly.

Deep-copy Options in restored db for stress test to avoid race with SetOptions() (#12015)
Summary: **Context** DB open will persist the `Options` in memory to options file and verify the file right after the write. The verification is done by comparing the options from parsing the written options file against the `Options` object in memory. Upon inconsistency, corruption such as https://github.com/facebook/rocksdb/blob/main/options/options_parser.cc#L725 will be returned. This verification assumes the `Options` object in memory is not changed from before the write till the verification. This assumption can break during [opening the restored db in stress test]( |

Fix db_stress FaultInjectionTestFS set up before DB open (#11958)
Summary: We saw frequent stress test failures with error messages like: ``` Verification failed for column family 0 key ...: value_from_db: , value_from_expected: ..., msg: GetEntity verification: Value not found: NotFound: ``` One cause for this is that data in WAL is lost after a crash. We initialize FaultInjectionTestFS to be not direct writable when write_fault_injection is enabled (see code change). This can cause the first WAL created during DB open to be lost if a db_stress is killed before the first WAL is synced. This PR initializes FaultInjectionTestFS to be direct writable. Note that FaultInjectionTestFS will be configured propertly for write fault injection after DB open in `RunStressTestImpl()`. So this change should not affect write fault injection coverage.

Fix crash_test_with_best_efforts_recovery (#11938)
Summary: Thanks ltamasi and ajkr for initial investigations on the test failure. Per the investigations, the following scenario is likely causing the test to fail. 1. Recovery is needed (could be any reason during crash test) 2. Trying to recover from the latest manifest fails (likely due to read error injection) 3. DB opens with recovery from the next manifest which is different from step 2. 4. Expected state is based on the manifest we tried and failed in step 2. 5. Two manifests used in step 2 and 3 are confirmed to have difference in LSM trees (Thanks ltamasi again for the finding). ``` 2023/10/05-11:24:18.942189 56341 [db/version_set.cc:6079] Trying to recover from manifest: /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/MANIFEST-007184 ... 2023/10/05-11:24:18.978007 56341 [db/version_set.cc:6079] Trying to recover from manifest: /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/MANIFEST-007180 ``` ``` [ltamasi@devbig1024.prn1 /tmp/x]$ ldb manifest_dump --hex --path=MANIFEST-007184_renamed_ > 2 [ltamasi@devbig1024.prn1 /tmp/x]$ ldb manifest_dump --hex --path=MANIFEST-007180_renamed_ > 1 [ltamasi@devbig1024.prn1 /tmp/x]$ diff 1 2 --- 1 2023-10-09 10:29:16.966215207 -0700 +++ 2 2023-10-09 10:29:11.984241645 -0700 @@ -13,7 +13,7 @@ 7174:3950254[1875617 .. 2203952]['000000000003415B000000000000012B000000000000007D' seq:1906214, type:1 ..

Make stopped writes block on recovery (#11879)
Summary: Relaxed the constraints for blocking when writes are stopped. When a recovery is already being attempted, we might as well let `!no_slowdown` writes wait on it in case it succeeds. This makes the user-visible behavior consistent across recovery flush and non-recovery flush. This enables `db_stress` to inject retryable (soft) flush read errors without having to handle user write failures. I changed `db_stress` a bit to permit injected errors in much more foreground operations as more admin operations (like `GetLiveFiles()`) can fail on a retryable error during flush.

Fix various failures in auto_readahead_size (#11884)
Summary: 1. **Error** in TestIterateAgainstExpected API - `Assertion index < pre_read_expected_values.size() && index < post_read_expected_values.size() failed.` **Fix** - `Prev` op is not supported with `auto_readahead_size`. So added support to Reseek in db_iter, if Prev is called. In BlockBasedTableIterator, index_iter_ already moves forward. So there is no way to do Prev from BlockBasedTableIterator. 2. **Error** - `void rocksdb::BlockBasedTableIterator::BlockCacheLookupForReadAheadSize(uint64_t, size_t, size_t&): Assertion index_iter_->value().handle.offset() == offset` **Fix** - Remove prefetch_buffer to be used when uncompressed dict is read. 3. ** Error in TestPrefixScan API - `db_stress: db/db_iter.cc:369: bool rocksdb::DBIter::FindNextUserEntryInternal(bool, const rocksdb::Slice*): Assertion !skipping_saved_key || CompareKeyForSkip(ikey_.user_key, saved_key_.GetUserKey()) > 0 failed.

Add the wide-column aware merge API to the stress tests (#11906)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/11906 The patch adds stress test coverage for the wide-column aware `FullMergeV3` API by implementing a new `DBStressWideMergeOperator`. This operator is similar to `PutOperator` / `PutOperatorV2` in the sense that its result is based on the last merge operand; however, the merge result can be either a plain value or a wide-column entity, depending on the value base encoded into the operand and the value of the `use_put_entity_one_in` stress test parameter. Following the same rule for merge results that we do for writes ensures that the queries issued by the validation logic receive the expected results. The new operator is used instead of `PutOperatorV2` whenever `use_put_entity_one_in` is positive. Note that the patch also makes it possible to set `use_put_entity_one_in` and `use_merge` (but not `use_full_merge_v1`) at the same time, giving `use_put_entity_one_in` precedence, so the stress test will use `PutEntity` for writes passing the `use_put_entity_one_in` check described above and `Merge` for any other writes.

Lookup ahead in block cache ahead to tune Readaheadsize (#11860)
Summary: Implement block cache lookup to determine readahead_size during scans. It's enabled if auto_readahead_size, block_cache and iterate_upper_bound - all three are set. Design - 1. Whenever there is a cache miss and FilePrefetchBuffer is called, a callback is made to determine readahead_size for that prefetching. 2. The callback iterates over index and do block cache lookup for each data block handle until existing readahead_size is reached. Then It removes the cache hit data blocks from end to calculate optimized readahead_size. 3. Since index_iter_ is moved, it stores block handles in a queue, and use that queue to get block handle instead of doing index_iter_->Next(). 4. This is for Sync scans. Async scans support is in progress. NOTE: The issue right now is after Seek and Next, if Prev is called, there is no way to do Prev operation. index_iter_ is already pointing to a different block. So it returns "Not supported" in that case with error message - "auto tuning of readahead size is not supported with Prev op" Pull Request resolved: https://github.com/facebook/rocksdb/pull/11860 Test Plan: - Added new unit test - crash_tests - Running scans locally to check for any regression Reviewed By: anand1976 Differential Revision: D49548118 Pulled By: akankshamahajan15 fbshipit-source-id: f1aee409a71b4ad9e5bf3610f43edf30c6630c78 |

DB Stress Fix - Commit pending value after checking for status (#11856)
Summary: We've seen occasional crash test failure in optimistic transaction DB with the following error message. ``` stderr: WARNING: prefix_size is non-zero but memtablerep != prefix_hash Verification failed for column family 0 key 0000000000001EDB0000000000000036787878787878 (789064): value_from_db: 010000000504070609080B0A0D0C0F0E111013121514171619181B1A1D1C1F1E212023222524272629282B2A2D2C2F2E313033323534373639383B3A3D3C3F3E, value_from_expected: , msg: MultiGet verification: Unexpected value found Crash-recovery verification failed :( No writes or ops? Verification failed :( ``` There was a possibility if the db stress crashes after `pending_expected_value.Commit()` but before `thread->shared->SafeTerminate();`, we may have expected value committed while actual DB value was not. Moving the `pending_expected_value.Commit()` after `s.ok()` check to fix the test.

Inject retryable write IOError when writing to SST files in stress test (#11829)
Summary: * db_crashtest.py now may set `write_fault_one_in` to 500 for blackbox and whitebox simple test. * Error injection only applies to writing to SST files. Flush error will cause DB to pause background operations and auto-resume. Compaction error will just re-schedule later. * File ingestion and back up tests are updated to check if the result status is due to an injected error. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11829 Test Plan: a full round of whitebox simple and blackbox simple crash test * `python3 ./tools/db_crashtest.py whitebox/blackbox --simple --write_fault_one_in=500` Reviewed By: ajkr Differential Revision: D49256962 Pulled By: cbi42 fbshipit-source-id: 68e0c9648d8e03bad39c7672b25d5500fc286d97 |

Fix test on IOActivity check for MultiGetEntity (#11850)
Summary:
After https://github.com/facebook/rocksdb/issues/11842 merged, we started to see some crash_test failures.
There is a flow inside `TestMultiGetEntity()` that it calls `GetEntity()` to compare the result between `MultiGetEntity()` and `GetEntity()`

Make RibbonFilterPolicy::bloom_before_level mutable (SetOptions()) (#11838)
Summary: An internal user wants to be able to dynamically switch between Bloom and Ribbon filters, without a custom FilterPolicy. Making `filter_policy` mutable would actually make issue https://github.com/facebook/rocksdb/issues/10079 worse, because it would be a race on a pointer field, not just on scalars. As a reasonable compromise until that is fixed, I am enabling dynamic control over Bloom vs. Ribbon choice by making RibbonFilterPolicy::bloom_before_level mutable, and doing that safely by using an atomic. I've also slightly tweaked the interpretation of that field so that setting it to INT_MAX really means "always Bloom." Pull Request resolved: https://github.com/facebook/rocksdb/pull/11838 Test Plan: unit tests added/extended. crash test updated for SetOptions call and tested under TSAN with amplified probability (lower set_options_one_in).

Add IOActivity.kMultiGetEntity (#11842)
Summary: - As a follow up from https://github.com/facebook/rocksdb/issues/11799, adding `Env::IOActivity::kMultiGetEntity` support to `DBImpl::MultiGetEntity()`. ## Minor Refactor - Because both `DBImpl::MultiGet()` and `DBImpl::MultiGetEntity()` call `DBImpl::MultiGetCommon()` which later calls `DBImpl::MultiGetWithCallback()` where we check `Env::IOActivity::kMultiGet`, minor refactor was needed so that we don't check `Env::IOActivity::kMultiGet` for `DBImpl::MultiGetEntity()`. - I still see more areas for refactoring to avoid duplicate code of checking IOActivity and setting it when Unknown, but this will be addressed separately. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11842 Test Plan: - Added the `ThreadStatus::OperationType::OP_MULTIGETENTITY` in `db_stress` to verify the pass-down IOActivity in a thread aligns with the actual activity the thread is doing. ``` python3 tools/db_crashtest.py blackbox --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 --duration=60 --interval=10 python3 tools/db_crashtest.py blackbox --simple --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 --duration=60 --interval=10 python3 tools/db_crashtest.py blackbox --cf_consistency --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 --duration=60 --interval=10 ``` Reviewed By: ltamasi Differential Revision: D49329575 Pulled By: jaykorean fbshipit-source-id: 05198f1d3f92e6be3d42a3d184bacb3ab2ce6923 |

Add new Iterator API Refresh(const snapshot*) (#10594)
Summary: This PR resolves https://github.com/facebook/rocksdb/issues/10487 & https://github.com/facebook/rocksdb/issues/10536, user code needs to call Refresh() periodically. The main code change is to support range deletions. A range tombstone iterator uses a sequence number as upper bound to decide which range tombstones are effective. During Iterator refresh, this sequence number upper bound needs to be updated for all range tombstone iterators under DBIter and LevelIterator. LevelIterator may create new table iterators and range tombstone iterator during scanning, so it needs to be aware of iterator refresh. The code path that propagates this change is `db_iter_->set_sequence(read_seq) -> MergingIterator::SetRangeDelReadSeqno() -> TruncatedRangeDelIterator::SetRangeDelReadSeqno() and LevelIterator::SetRangeDelReadSeqno()`. This change also fixes an issue where range tombstone iterators created by LevelIterator may access ReadOptions::snapshot, even though we do not explicitly require users to keep a snapshot alive after creating an Iterator. Pull Request resolved: https://github.com/facebook/rocksdb/pull/10594 Test Plan: * New unit tests. * Add Iterator::Refresh(snapshot) to stress test. Note that this change only adds tests for refreshing to the same snapshot since this is the main target use case. TODO in a following PR: * Stress test Iterator::Refresh() to different snapshots or no snapshot.

GetEntity Support for ReadOnlyDB and SecondaryDB (#11799)
Summary: `GetEntity` API support for ReadOnly DB and Secondary DB. - Introduced `GetImpl()` with `GetImplOptions` in `db_impl_readonly` and refactored current `Get()` logic into `GetImpl()` so that look up logic can be reused for `GetEntity()` (Following the same pattern as `DBImpl::Get()` and `DBImpl::GetEntity()`) - Introduced `GetImpl()` with `GetImplOptions` in `db_impl_secondary` and refactored current `GetImpl()` logic. This is to make `DBImplSecondary::Get/GetEntity` consistent with `DBImpl::Get/GetEntity` and `DBImplReadOnly::Get/GetEntity` - `GetImpl()` in `db_impl` is now virtual. both `db_impl_readonly` and `db_impl_secondary`'s `Get()` override are no longer needed since all three dbs now have the same `Get()` which calls `GetImpl()` internally. - `GetImpl()` in `DBImplReadOnly` and `DBImplSecondary` now pass in `columns` instead of `nullptr` in lookup functions like `memtable->get()` - Introduced `GetEntity()` API in `DBImplReadOnly` and `DBImplSecondary` which simply calls `GetImpl()` with `columns` set in `GetImplOptions`. - Introduced `Env::IOActivity::kGetEntity` and set read_options.io_activity to `Env::IOActivity::kGetEntity` for `GetEntity()` operations (in db_impl) Pull Request resolved: https://github.com/facebook/rocksdb/pull/11799 Test Plan: **Unit Tests** - Added verification in `DBWideBasicTest::PutEntity` by Reopening DB as ReadOnly with the same setup. - Added verification in `DBSecondaryTest::ReopenAsSecondary` by calling `PutEntity()` and `GetEntity()` on top of existing `Put()` and `Get()` - `make -j64 check` **Crash Tests** - `python3 tools/db_crashtest.py blackbox --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 --duration=60 --inter val=10` - `python3 tools/db_crashtest.py blackbox --simple --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 ` - `python3 tools/db_crashtest.py blackbox --cf_consistency --max_key=25000000 --write_buffer_size=4194304 --max_bytes_for_level_base=2097152 --target_file_size_base=2097152 --periodic_compaction_seconds=0 --use_put_entity_one_in=10 --use_get_entity=1 --duration=60 --inter val=10` Reviewed By: ltamasi Differential Revision: D49037040 Pulled By: jaykorean fbshipit-source-id: a0648253ded6e91af7953de364ed3c6bf163626b |

Run db_stress for final time to ensure un-interrupted validation (#11592)
Summary: In blackbox tests, db_stress command always run with timeout. Timeout can happen during validation, leaving some of the keys not checked. Since key validation is done in order, it is quite likely that keys those are towards to the end of the set are never validated.

Delay bottommost level single file compactions (#11701)
Summary: For leveled compaction, RocksDB has a special kind of compaction with reason "kBottommmostFiles" that compacts bottommost level files to clear data held by snapshots (more detail in https://github.com/facebook/rocksdb/issues/3009). Such compactions can happen soon after a relevant snapshot is released. For some use cases, a bottommost file may contain only a small amount of keys that can be cleared, so compacting such a file has a high write amp. In addition, these bottommost files may be compacted in compactions with reason other than "kBottommmostFiles" if we wait for some time (so that enough data is ingested to trigger such a compaction). This PR introduces an option `bottommost_file_compaction_delay` to specify the delay of these bottommost level single file compactions. * The main change is in `VersionStorageInfo::ComputeBottommostFilesMarkedForCompaction()` where we only add a file to `bottommost_files_marked_for_compaction_` if it oldest_snapshot is larger than its non-zero largest_seqno **and** the file is old enough. Note that if a file is not old enough but its largest_seqno is less than oldest_snapshot, we exclude it from the calculation of `bottommost_files_mark_threshold_`. This makes the change simpler, but such a file's eligibility for compaction will only be checked the next time `ComputeBottommostFilesMarkedForCompaction()` is called. This happens when a new Version is created (compaction, flush, SetOptions()...), a new enough snapshot is released (`VersionStorageInfo::UpdateOldestSnapshot()`) or when a compaction is picked and compaction score has to be re-calculated. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11701 Test Plan: * Add two unit tests to test when bottommost_file_compaction_delay > 0. * Ran crash test with the new option.

Placeholder for AutoHyperClockCache, more (#11692)
Summary:
* The plan is for AutoHyperClockCache to be selected when HyperClockCacheOptions::estimated_entry_charge == 0, and in that case to use a new configuration option min_avg_entry_charge for determining an extreme case maximum size for the hash table. For the placeholder, a hack is in place in HyperClockCacheOptions::MakeSharedCache() to make the unit tests happy despite the new options not really making sense with the current implementation.
* Mostly updating and refactoring tests to test both the current HCC (internal name FixedHyperClockCache) and a placeholder for the new version (internal name AutoHyperClockCache).
* Simplify some existing tests not to depend directly on cache type.
* Type-parameterize the shard-level unit tests, which unfortunately requires more syntax like `this->` in places for disambiguation.
* Added means of choosing auto_hyper_clock_cache to cache_bench, db_bench, and db_stress, including add to crash test.
* Add another templated class BaseHyperClockCache to reduce future copy-paste
* Added ReportProblems support to cache_bench
* Added a DEBUG-level diagnostic to ReportProblems for the variance in load factor throughout the table, which will become more of a concern with linear hashing to be used in the Auto implementation. Example with current Fixed HCC:
```
2023/08/10-13:41:41.602450 6ac36 [DEBUG] [che/clock_cache.cc:1507] Slot occupancy stats: Overall 49% (129008/262144), Min/Max/Window = 39%/60%/500, MaxRun{Pos/Neg} = 18/17
```
In other words, with overall occupancy of 49%, the lowest across any 500 contiguous cells is 39% and highest 60%. Longest run of occupied is 18 and longest run of unoccupied is 17. This seems consistent with random samples from a uniform distribution.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11692
Test Plan: Shouldn't be any meaningful changes yet to production code or to what is tested, but there is temporary redundancy in testing until the new implementation is plugged in.

Group rocksdb.sst.read.micros stat by different user read IOActivity + misc (#11444)
Summary:
**Context/Summary:**
- Similar to https://github.com/facebook/rocksdb/pull/11288 but for user read such as `Get(), MultiGet(), DBIterator::XXX(), Verify(File)Checksum()`.
- For this, I refactored some user-facing `MultiGet` calls in `TransactionBase` and various types of `DB` so that it does not call a user-facing `Get()` but `GetImpl()` for passing the `ReadOptions::io_activity` check (see PR conversation)
- New user read stats breakdown are guarded by `kExceptDetailedTimers` since measurement shows they have 4-5% regression to the upstream/main.
- Misc
- More refactoring: with https://github.com/facebook/rocksdb/pull/11288, we complete passing `ReadOptions/IOOptions` to FS level. So we can now replace the previously [added](https://github.com/facebook/rocksdb/pull/9424) `rate_limiter_priority` parameter in `RandomAccessFileReader`'s `Read/MultiRead/Prefetch()` with `IOOptions::rate_limiter_priority`
- Also, `ReadAsync()` call time is measured in `SST_READ_MICRO` now

Allow TryAgain in db_stress with optimistic txn, and refactoring (#11653)
Summary: In rare cases, optimistic transaction commit returns TryAgain. This change tolerates that intentional behavior in db_stress, up to a small limit in a row. This way, we don't miss a possible regression with excessive TryAgain, and trying again (rolling back the transaction) should have a well renewed chance of success as the writes will be associated with fresh sequence numbers. Also, some of the APIs were not clear about Transaction semantics, so I have clarified: * (Best I can tell....) Destroying a Transaction is safe without calling Rollback() (or at least should be). I don't know why it's a common pattern in our test code and examples to rollback before unconditional destruction. Stress test updated not to call Rollback unnecessarily (to test safe destruction). * Despite essentially doing what is asked, simply trying Commit() again when it returns TryAgain does not have a chance of success, because of the transaction being bound to the DB state at the time of operations before Commit. Similar logic applies to Busy AFAIK. Commit() API comments updated, and expanded unit test in optimistic_transaction_test. Also also, because I can't stop myself, I refactored a good portion of the transaction handling code in db_stress. * Avoid existing and new copy-paste for most transaction interactions with a new ExecuteTransaction (higher-order) function. * Use unique_ptr (nicely complements removing unnecessary Rollbacks) * Abstract out a pattern for safely calling std::terminate() and use it in more places. (The TryAgain errors we saw did not have stack traces because of "terminate called recursively".) Intended follow-up: resurrect use of `FLAGS_rollback_one_in` but also include non-trivial cases Pull Request resolved: https://github.com/facebook/rocksdb/pull/11653 Test Plan: this is the test :) Also, temporarily bypassed the new retry logic and boosted the chance of hitting TryAgain. Quickly reproduced the TryAgain error. Then re-enabled the new retry logic, and was not able to hit the error after running for tens of minutes, even with the boosted chances.

Initialize StressTest::optimistic_txn_db_ in ctor (#11547)
Summary: `StressTest::optimistic_txn_db_` is currently not initialized by the constructor, which can lead to assertion failures down the line in `StressTest::Open`.

Stress/Crash Test for OptimisticTransactionDB (#11513)
Summary: Context: OptimisticTransactionDB has not been covered by db_stress (including crash test) like TransactionDB. 1. Adding the following gflag options to to test OptimisticTransactionDB - `use_optimistic_txn`: When true, open OptimisticTransactionDB to test - `occ_validation_policy`: `OccValidationPolicy::kValidateParallel = 1` by default. - `share_occ_lock_buckets`: Use shared occ locks - `occ_lock_bucket_count`: 500 by default. Number of buckets to use for shared occ lock. 2. Opening OptimisticTransactionDB and NewTxn/Commit added per `use_optimistic_txn` flag in `db_stress_test_base.cc` 3. OptimisticTransactionDB blackbox/whitebox test added in crash_test.mk Please note that the existing flag `use_txn` is being used here. When `use_txn == true` and `use_optimistic_txn == false`, we use `TransactionDB` (a.k.a. pessimistic transaction db). When both `use_txn` and `use_optimistic_txn` are true, we use `OptimisticTransactionDB`. If `use_txn == false` but `use_optimistic_txn == true` throw error with message _"You cannot set use_optimistic_txn true while use_txn is false. Please set use_txn true if you want to use OptimisticTransactionDB"_.

Add WaitForCompact with WaitForCompactOptions to public API (#11436)
Summary: Context: This is the first PR for WaitForCompact() Implementation with WaitForCompactOptions. In this PR, we are introducing `Status WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` in the public API. This currently utilizes the existing internal `WaitForCompact()` implementation (with default abort_on_pause = false). `abort_on_pause` has been moved to `WaitForCompactOptions&`. In the later PRs, we will introduce the following two options in `WaitForCompactOptions` 1. `bool flush = false` by default - If true, flush before waiting for compactions to finish. Must be set to true to ensure no immediate compactions (except perhaps periodic compactions) after closing and re-opening the DB. 2. `bool close_db = false` by default - If true, will also close the DB upon compactions finishing. 1. struct `WaitForCompactOptions` added to options.h and `abort_on_pause` in the internal API moved to the option struct. 2. `Status WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` introduced in `db.h` 3. Changed the internal WaitForCompact() to `WaitForCompact(const WaitForCompactOptions& wait_for_compact_options)` and checks for the `abort_on_pause` inside the option. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11436 Test Plan: Following tests added - `DBCompactionTest::WaitForCompactWaitsOnCompactionToFinish` - `DBCompactionTest::WaitForCompactAbortOnPauseAborted` - `DBCompactionTest::WaitForCompactContinueAfterPauseNotAborted` - `DBCompactionTest::WaitForCompactShutdownWhileWaiting` - `TransactionTest::WaitForCompactAbortOnPause` NOTE: `TransactionTest::WaitForCompactAbortOnPause` was added to use `StackableDB` to ensure the wrapper function is in place.

Improve comment of ExpectedValue in db stress (#11456)
Summary: **Context/Summary:** https://github.com/facebook/rocksdb/pull/11424 made me realize there are a couple gaps in my `ExpectedValue` comments so I updated them, along with separating `ExpectedValue` into separate files so it's clearer that `ExpectedValue` can be used without updating `ExpectedState` (e.g, TestMultiGet() where we care about value base of expected value but not updating the ExpectedState).

Remove wait_unscheduled from waitForCompact internal API (#11443)
Summary: Context: In pull request https://github.com/facebook/rocksdb/issues/11436, we are introducing a new public API `waitForCompact(const WaitForCompactOptions& wait_for_compact_options)`. This API invokes the internal implementation `waitForCompact(bool wait_unscheduled=false)`. The unscheduled parameter indicates the compactions that are not yet scheduled but are required to process items in the queue. In certain cases, we are unable to wait for compactions, such as during a shutdown or when background jobs are paused. It is important to return the appropriate status in these scenarios. For all other cases, we should wait for all compaction and flush jobs, including the unscheduled ones. The primary purpose of this new API is to wait until the system has resolved its compaction debt. Currently, the usage of `wait_unscheduled` is limited to test code. This pull request eliminates the usage of wait_unscheduled. The internal `waitForCompact()` API now waits for unscheduled compactions unless the db is undergoing a shutdown. In the event of a shutdown, the API returns `Status::ShutdownInProgress()`. Additionally, a new parameter, `abort_on_pause`, has been introduced with a default value of `false`. This parameter addresses the possibility of waiting indefinitely for unscheduled jobs if `PauseBackgroundWork()` was called before `waitForCompact()` is invoked. By setting `abort_on_pause` to `true`, the API will immediately return `Status::Aborted`. Furthermore, all tests that previously called `waitForCompact(true)` have been fixed. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11443 Test Plan: Existing tests that involve a shutdown in progress: - DBCompactionTest::CompactRangeShutdownWhileDelayed - DBTestWithParam::PreShutdownMultipleCompaction - DBTestWithParam::PreShutdownCompactionMiddle Reviewed By: pdillinger Differential Revision: D45923426 Pulled By: jaykorean fbshipit-source-id: 7dc93fe6a6841a7d9d2d72866fa647090dba8eae |
