Move file tracking in VersionEditHandlerPointInTime to VersionBuilder (#12928)
Summary: `VersionEditHandlerPointInTime` is tracking found files, missing files, intermediate files in order to decide to build a `Version` on negative edge trigger (transition from valid to invalid) without applying the current `VersionEdit`. However, applying `VersionEdit` and check completeness of a `Version` are specialization of `VersionBuilder`. More importantly, when we augment best efforts recovery to recover not just complete point in time Version but also a prefix of seqno for a point in time Version, such checks need to be duplicated in `VersionEditHandlerPointInTime` and `VersionBuilder`. To avoid this, this refactor move all the file tracking functionality in `VersionEditHandlerPointInTime` into `VersionBuilder`. To continue to let `VersionEditHandlerPIT` do the edge trigger check and build a `Version` before applying the current `VersionEdit`, a suite of APIs to supporting creating a save point and its associated functions are added in `VersionBuilder` to achieve this.

Disable WAL recycling in crash test; reproducer for recovery data loss (#12918)
Summary: I was investigating a crash test failure with "Corruption: SST file is ahead of WALs" which I haven't reproduced, but I did reproduce a data loss issue on recovery which I suspect could be the same root problem. The problem is already somewhat known (see https://github.com/facebook/rocksdb/issues/12403 and https://github.com/facebook/rocksdb/issues/12639) where it's only safe to recovery multiple recycled WAL files with trailing old data if the sequence numbers between them are adjacent (to ensure we didn't lose anything in the corrupt/obsolete WAL tail). However, aside from disableWAL=true, there are features like external file ingestion that can increment the sequence numbers without writing to the WAL. It is simply unsustainable to worry about this kind of feature interaction limiting where we can consume sequence numbers. It is very hard to test and audit as well. For reliable crash recovery of recycled WALs, we need a better way of detecting that we didn't drop data from one WAL to the next. Until then, let's disable WAL recycling in the crash test, to help stabilize it. Ideas for follow-up to fix the underlying problem: (a) With recycling, we could always sync the WAL before opening the next one. HOWEVER, this potentially very large sync could cause a big hiccup in writes (vs. O(1) sized manifest sync). (a1) The WAL sync could ensure it is truncated to size, or (a2) By requiring track_and_verify_wals_in_manifest, we could assume that the last synced size in the manifest is the final usable size of the WAL. (It might also be worth avoiding truncating recycled WALs.) (b) Add a new mechanism to record and verify the final size of a WAL without requiring a sync. (b1) By requiring track_and_verify_wals_in_manifest, this could be new WAL metadata recorded in the manifest (at the time of switching WALs). Note that new fields of WalMetadata are not forward-compatible, but a new kind of manifest record (next to WalAddition, WalDeletion; e.g. WalCompletion) is IIRC forward-compatible. (b2) A new kind of WAL header entry (not forward compatible, unfortunately) could record the final size of the previous WAL.

Fix CreateCheckpoint not handling failed CleanStagingDirectory well (#12894)
Summary: **Context/Summary:** `CleanStagingDirectory()` is called when the temporary .tmp folder we use to create checkpoint is not empty to begin with. Expanded fault injection can make this call fail e.g, `Delete file /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/.checkpoint17.tmp/012393.sst -- IO error: injected metadata write error`. But The result of `CleanStagingDirectory()` is ignored in `CreateCheckpoint()`. So the injected IO error can't be propagated to db stress test and handled correctly. Hence we see `While mkdir: /dev/shm/rocksdb_test/rocksdb_crashtest_blackbox/.checkpoint17.tmp: File exists` when we try to re-use a non-empty .tmp folder for new snapshots.

Fix file deletions in DestroyDB not rate limited (#12891)
Summary: Make `DestroyDB` slowly delete files if it's configured and enabled via `SstFileManager`. It's currently not available mainly because of DeleteScheduler's logic related to tracked total_size_ and total_trash_size_. These accounting and logic should not be applied to `DestroyDB`. This PR adds a `DeleteUnaccountedDBFile` util for this purpose which deletes files without accounting it. This util also supports assigning a file to a specified trash bucket so that user can later wait for a specific trash bucket to be empty. For `DestroyDB`, files with more than 1 hard links will be deleted immediately. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12891 Test Plan: Added unit tests, existing tests.

Fix filter partition size logic (#12904)
Summary: Was checking == a desired number of entries added to a filter, when the combination of whole key and prefix filtering could add more than one entry per table internal key. This could lead to unnecessarily large filter partitions, which could affect performance and block cache fairness. Also (only somewhat related because of other work in progress): * Some variable renaming and a new assertion in BlockBasedTableBuilder, to add some clarity. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12904 Test Plan: If you add assertion logic to the base revision checking that the partition cut is requested whenever `keys_added_to_partition_ >= keys_per_partition_`, it fails on a number of db_bloom_filter_test tests. However, such an assertion in the revised code would be essentially redundant with the new logic. If I added a regression test for this, it would be tricky and fragile, so I don't think it's important enough to chase and maintain. (Open to suggestions / input.)

Fix a data race affecting the background error status (#12910)
Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12910 There is currently a call to `GetBGError()` in `DBImpl::WriteImplWALOnly()` where the DB mutex is (incorrectly) not held, leading to a data race. Technically, we could acquire the mutex here but instead, the patch removes the affected check altogether, since the same check is already performed (in a thread-safe manner) in the subsequent call to `PreprocessWrite()`.

Use compensated file size for intra-L0 compaction (#12878)
Summary: In leveled compaction, we pick intra-L0 compaction instead of L0->Lbase whenever L0 size is small. When L0 files contain many deletions, it makes more sense to compact then down instead of accumulating tombstones in L0. This PR uses compensated_file_size when computing L0 size for determining intra-L0 compaction. Also scale down the limit on total L0 size further to be more cautious about accumulating data in L0.

Attempt to fix the nightly build-linux-clang-13-asan-ubsan-with-folly build
Summary: https://github.com/facebook/rocksdb/pull/12801 updated the version of `folly` used in RocksDB builds to a revision that requires `g++` version 10 when built with a GNU toolchain. This shouldn't really matter for this nightly GitHub Actions job, since we're supposed to be building with `clang++-13`; however, due to the way the compilers had been set, seems like we were historically only building RocksDB with `clang` (and `folly` with `gcc-9`, which led to a broken build after the update). Attempt to fix this by setting `CC` / `CXX` to `clang` / `clang++` in the job's environment.

Make transaction name conflict check more robust (#12895)
Summary: The `PessimisticTransaction::SetName()` code checks for an existing txn of the given name before registering the new txn. However, this is not atomic, which could result in a race condition if two txns try to register with the same name. Both might succeed and lead to unpredictable behavior. This PR makes the test and set atomic.

Add an option to toggle timestamp based validation for the whole DB (#12857)
Summary: As titled. This PR adds a `TransactionDBOptions` field `enable_udt_validation` to allow user to toggle the timestamp based validation behavior across the whole DB. When it is true, which is the default value and the existing behavior. A recap of what this behavior is: `GetForUpdate` does timestamp based conflict checking to make sure no other transaction has committed a version of the key tagged with a timestamp equal to or newer than the calling transaction's `read_timestamp_` the user set via `SetReadTimestampForValidation`. When this field is set to false, we disable timestamp based validation for the whole DB. MyRocks find it hard to find a read timestamp for this validation API, so we added this flexibility.

Handle injected write error after successful WAL write in crash test + misc (#12838)
Summary: **Context/Summary:** We discovered the following false positive in our crash test lately: (1) PUT() writes k/v to WAL but fails in `ApplyWALToManifest()`. The k/v is in the WAL (2) Current stress test logic will rollback the expected state of such k/v since PUT() fails (3) If the DB crashes before recovery finishes and reopens, the WAL will be replayed and the k/v is in the DB while the expected state have been roll-backed. We decided to leave those expected state to be pending until the loop-write of the same key succeeds. Bonus: Now that I realized write to manifest can also fail the write which faces the similar problem as https://github.com/facebook/rocksdb/pull/12797, I decided to disable fault injection on user write per thread (instead of globally) when tracing is needed for prefix recovery; some refactory Pull Request resolved: https://github.com/facebook/rocksdb/pull/12838 Test Plan: Rehearsal CI Run

Fix manifest_number_ point to invalid file (#12882)
Summary: This PR fix `VersionSet`'s `manifest_number_` could be pointing to an invalid number intermediately. This happens when a new manifest roll is attempted but fast failed after loading table handlers and before the new manifest file creation/writing is actually attempted. In theory, a later manifest roll effort will overthrow this intermediate invalid in memory state. There is on harm when the DB crashes in this invalid state either. But efforts that takes a file snapshot of the DB like backup will incorrectly try to copy a non existing manifest file.

Refactor IndexBuilder::AddIndexEntry (#12867)
Summary: Something I am working on is going to expand usage of `BlockBasedTableBuilder::Rep::last_key`, but the existing code contract for `IndexBuilder::AddIndexEntry` makes that difficult because it modifies its `last_key` parameter to be the separator value recorded in the index, often something between the two boundary keys. This change primarily changes the contract of that function and related functions to separate function inputs and outputs, without sacrificing efficiency. For efficiency, a reusable scratch string buffer is provided by the caller, which the callee can use (or not) in returning a result Slice. That should yield a performance improvement as we are reusing a buffer for keys rather than copying into a new one each time in the FindShort* functions, without any additional string copies or conditional branches. Additional improvements in PartitionedIndexBuilder specifically: * Reduce string copies by eliminating `sub_index_last_key_` and instead tracking the key for the next partition in a placeholder Entry. * Simplify code and improve code quality by changing `sub_index_builder_` to unique_ptr. * Eliminate unnecessary NewFlushBlockPolicy call/object. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12867 Test Plan: existing tests, crash test. Will validate performance along with the change this is setting up.

Fix duplicate WAL entries caused by write after error recovery (#12873)
Summary: **Context/Summary:** We recently discovered a case where write of the same key right after error recovery of a previous failed write of the same key finishes causes two same WAL entries, violating our assertion. This is because we don't advance seqno on failed write and reuse the same WAL containing the failed write for the new write if the memtable at the time is empty. This PR reuses the flush path for an empty memtable to switch WAL and update min WAL to keep in error recovery flush as well as updates the INFO log message for clarity. ``` 2024/07/17-15:01:32.271789 327757 (Original Log Time 2024/07/17-15:01:25.942234) [/flush_job.cc:1017] [default] [JOB 2] Level-0 flush table https://github.com/facebook/rocksdb/issues/9: 0 bytes OK It's an empty SST file from a successful flush so won't be kept in the DB 2024/07/17-15:01:32.271798 327757 (Original Log Time 2024/07/17-15:01:32.269954) [/memtable_list.cc:560] [default] Level-0 commit flush result of table https://github.com/facebook/rocksdb/issues/9 started 2024/07/17-15:01:32.271802 327757 (Original Log Time 2024/07/17-15:01:32.271217) [/memtable_list.cc:760] [default] Level-0 commit flush result of table https://github.com/facebook/rocksdb/issues/9: memtable https://github.com/facebook/rocksdb/issues/1 done ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/12873 Test Plan: New UT that failed before this PR with following assertion failure (i.e, duplicate WAL entries) and passes after ``` db_wal_test: db/write_batch.cc:2254: rocksdb::Status rocksdb::{anonymous}::MemTableInserter::PutCFImpl(uint32_t, const rocksdb::Slice&, const rocksdb::Slice&, rocksdb::ValueType, RebuildTxnOp, const ProtectionInfoKVOS64*) [with RebuildTxnOp = rocksdb::{anonymous}::MemTableInserter::PutCF(uint32_t, const rocksdb::Slice&, const rocksdb::Slice&)::<lambda(rocksdb::WriteBatch*, uint32_t, const rocksdb::Slice&, const rocksdb::Slice&)>; uint32_t = unsigned int; rocksdb::ProtectionInfoKVOS64 = rocksdb::ProtectionInfoKVOS<long unsigned int>]: Assertion `seq_per_batch_' failed. ``` Reviewed By: anand1976 Differential Revision: D59884468 Pulled By: hx235 fbshipit-source-id: 5d854b719092552c69727a979f269fb7f6c39756 |

Support ingesting SST files generated by a live DB (#12750)
Summary: ... to enable use cases like using RocksDB to merge sort data for ingestion. A new file ingestion option `IngestExternalFileOptions::allow_db_generated_files` is introduced to allows users to ingest SST files generated by live DBs instead of SstFileWriter. For now this only works if the SST files being ingested have zero as their largest sequence number AND do not overlap with any data in the DB (so we can assign seqno 0 which matches the seqno of all ingested keys). The feature is marked the option as experimental for now. Main changes needed to enable this: - ignore CF id mismatch during ingestion - ignore the missing external file version table property Rest of the change is mostly in new unit tests. A previous attempt is in https://github.com/facebook/rocksdb/issues/5602.

Fix race between manifest error recovery and file ingestion (#12871)
Summary: This PR fixes an assertion failure in `DBImpl::ResumeImpl` - `assert(!versions_->descriptor_log_)`. In `VersionSet`, `descriptor_log_` has a pointer to the current MANIFEST writer. When there's an error updating the manifest, `descriptor_log_` is reset, and the error recovery thread checks `io_status()` in `VersionSet` and attempts to write a new MANIFEST. If another DB manipulation happens at the same time (like external file ingestion, column family manipulation etc), it calls `LogAndApply`, which also attempts to write a new MANIFEST. The assertion in `ResumeImpl` might fail in this case since the other MANIFEST writer may have updated `descriptor_log_`. To prevent the assertion, this fix updates both `io_status_` and `descriptor_log_` while holding the DB mutex. The other option would have been to simply remove the assert. But I think its important to have it to ensure the invariant that `io_status_` is cleared if the MANIFEST is written successfully, and this fix makes things easier to reason about.

Reduce cases of impacted performance from bug fix (#12874)
Summary: https://github.com/facebook/rocksdb/issues/12872 was a bit too gross of a fix, because we still don't need to track previous prefix in FullFilterBlockBuilder for many non-partitioned use cases. This basically narrows the fix (and potentail CPU regression) to partitioned+prefix filter cases, which are the cases that needed to be fixed. A better efficiency fix would still be nice but not as high of a priority.

Fix major bug with prefixes, SeekForPrev, and partitioned filters (#12872)
Summary: Basically, the fix in https://github.com/facebook/rocksdb/issues/8137 was incomplete (and I missed it in the review), because if `whole_key_filtering` is false, then `last_prefix_str_` will never be set to non-empty and the fix doesn't work. Also related to https://github.com/facebook/rocksdb/issues/5835. This is intended as a safe, simple fix that will regress CPU efficiency slightly (for `whole_key_filtering=false` cases, because of extra prefix string copies during flush & compaction). An efficient fix is not possible without some substantial refactoring. Also in this PR: new test DBBloomFilterTest.FilterNumEntriesCoalesce tests an adjacent code path that was previously untested for its effect of ensuring the number of unique prefixes and keys is tracked properly when both prefixes and whole keys are going into a filter. (Test fails when either of the two code segments checking for duplicates is disabled.) In addition, the same test would fail before the main bug fix here because the code would inappropriately add the empty string to the filter (because of unmodified `last_prefix_str_`). Pull Request resolved: https://github.com/facebook/rocksdb/pull/12872 Test Plan: In addition to DBBloomFilterTest.FilterNumEntriesCoalesce, extended DBBloomFilterTest.SeekForPrevWithPartitionedFilters to cover the broken case.

Move WAL sync before memtable insertion (#12869)
Summary: **Context/Summary:** WAL sync currently happens after memtable write. This causes inconvenience in stress test as we can't simply rollback the ExpectedState when write fails due to injected WAL sync error so something complicated like https://github.com/facebook/rocksdb/pull/12838 might be needed.

Fix unhandled MANIFEST write errors (#12865)
Summary: The failure of `WriteCurrentStateToManifest()` in `VersionSet::ProcessManifestWrites()` was not handled properly. If it failed, `manifest_io_status` was not updated, leading to `manifest_file_number_` being updated to the newly created manifest even though its bad. This would lead to the bad manifest immediately getting deleted, and also the good manifest (referenced by `CURRENT`) getting deleted by obsolete file deletion because of `manifest_file_number_` not referencing its number.

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
thread id: 718114, thread status: , cf_name pikachu
/__w/rocksdb/rocksdb/db/db_test.cc:4817: Failure
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.

Support read & write with unsynced data in FaultInjectionTestFS (#12852)
Summary: Follow-up to https://github.com/facebook/rocksdb/issues/12729 and others to fix FaultInjectionTestFS handling the case where a live WAL is being appended to and synced while also being copied for checkpoint or backup, up to a known flushed (but not necessarily synced) prefix of the file. It was tricky to structure the code in a way that could handle a tricky race with Sync in another thread (see code comments, thanks Changyu) while maintaining good performance and test-ability. For more context, see the call to FlushWAL() in DBImpl::GetLiveFilesStorageInfo(). Also, the unit test for https://github.com/facebook/rocksdb/issues/12729 was neutered by https://github.com/facebook/rocksdb/issues/12797, and this re-enables the functionality it is testing. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12852 Test Plan: unit test expanded/updated. Local runs of blackbox_crash_test. The implementation is structured so that a multi-threaded unit test is not needed to cover at least the code lines, as the race handling is folded into "catch up after returning unsynced and then a sync."

Summary:
This PR fix a bug for recovering a prepared Transaction that can contain user-defined timestamps.
The `Transaction::Put` type of APIs expect the key provided to be user key without timestamps. When the original transaction added a key for a column family that enables user-defined timestamps, say of size 8. Internally `WriteBatch::Put` will leave a placeholder 8 bytes for the final commit timestamp. For example:
