Don't take archived log size into account when calculating log size for flush (#12680)
Summary: **Context/Summary:** It seems unreasonable to take the archived log size into account when calculating log size **for flush** in method CreateCheckpoint. If the user sets WAL_ttl_seconds or WAL_size_limit_MB, the argument _log_size_for_flush_ can easily be reached due to the size of the archived dir. As a result, the flush may always be triggered. **Test** corverd by ./checkpoint_test Pull Request resolved: https://github.com/facebook/rocksdb/pull/12680 Reviewed By: jaykorean Differential Revision: D59097904 Pulled By: ajkr fbshipit-source-id: 0ed29c1b078d8f40b85288541b008e00dbc517d3 |

Ignore non-critical IO error in BlockCacheLookupForReadAheadSize() in crash test (#12814)
Summary:
**Context/Summary:**
Error in `BlockCacheLookupForReadAheadSize()` is not critical enough to return such error in read path. That's because the worst case is to not have any read ahead. See below comment.

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

Add info logging via callback to C api. (#12537)
Summary: I'd like to get this in so the Rust folks can integrate with their splendid logging/tracing frameworks; will be hugely appreciated. 🙏🏻 The infolog capabilities for C embeddings are quite spartan. LOG files were generated involuntarily until redirection to stderr was added by https://github.com/facebook/rocksdb/issues/12262; still insufficient for apps which cannot tolerate pollution of their stdio and tend to have existing logging frameworks to tie into for that. Adds a very minimal derive of Logger around a C callback, written in the spirit, useful for FFI interfaces from other languages to integrate infolog.

Fix possible double-free on TruncatedRangeDelIterator (#12805)
Summary: Not sure where or how it happens, but using a recent CircleCI failure I got a reliable db_stress reproducer. Using std::unique_ptr appropriately for managing them has apparently (and unsurprisingly) fixed the problem without needing to know exactly where the problem was. Suggested follow-up: * Three or even four levels of pointers is very confusing to work with. Surely this part can be cleaned up to be simpler. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12805 Test Plan: Reproducer passes, plus ASAN test and crash test runs.

Fix assertion failure in ConstructFragmentedRangeTombstones() (#12796)
Summary: the assertion `assert(!IsFragmentedRangeTombstonesConstructed(false));` assumes ConstructFragmentedRangeTombstones() is called only once for a memtable.

Fix possible crash in failure to sync some WALs (#12789)
Summary: I believe this was possible with recyclable logs before recent work like https://github.com/facebook/rocksdb/issues/12734, but this cleans up a couple of possible crashes revealed by the crash test. A WAL with a nullptr file writer (already closed) can persist in `logs_` if a later WAL fails to sync. In case of any WAL sync failures, we don't record WAL syncs to the manifest. Thus, even if a WAL is fully synced and closed, we might need to keep it on the `logs_` list so that we know to record its sync to the manifest if there should be a successful sync next time. (However, I believe that's future-looking because currently any failure in WAL sync is considered non-recoverable.) I don't believe this was likely enough before recent changes to warrant a release note (if it was possible).

Fix heap-use-after-free in MultiCfIteratorImpl (#12784)
Summary: # Summary When changing the direction of the multi-cf-iter, we do this by `Seek(current_key)` (if changing from backward to forward) or `SeekForPrev(current_key)` (if forward -> backward) in the child iters and rebuild the heap. `Slice target` is just a pointer and contents are not guaranteed to be the same after re-init the heap. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12784 Test Plan: I was able to steadily repro by building with `COMPILE_WITH_ASAN=1` running db_stress. ``` COMPILE_WITH_ASAN=1 make

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.

Add CompactForTieringCollector to support automatically trigger compaction for tiering use case (#12760)
Summary: This PR adds user property collector factory `CompactForTieringCollectorFactory` to support observe SST file and mark it as need compaction for fast tracking data to the proper tier. A triggering ratio `compaction_trigger_ratio_` can be configured to achieve the following: 1) Setting the ratio to be equal to or smaller than 0 disables this collector 2) Setting the ratio to be within (0, 1] will write the number of observed eligible entries into a user property and marks a file as need-compaction when aforementioned condition is met. 3) Setting the ratio to be higher than 1 can be used to just writes the user table property, and not mark any file as need compaction. For a column family that does not enable tiering feature, even if an effective configuration is provided, this collector is still disabled. For a file that is already on the last level, this collector is also disabled.

MultiCfIterator - Handle case of invalid key from child iter manual prefix iteration (#12773)
Summary: Instead of completely disallowing `MultiCfIterator` when one or more child iterators will do manual prefix iteration (as suggested in https://github.com/facebook/rocksdb/issues/12770 ), just let `MultiCfIterator` operate as is even when there's a possibility of undefined result from child iterators. If one or more child iterators cause the heap to be empty, just return early and `Valid()` will return false. It is still possible that heap is not empty when one or more child iterators are returning wrong keys. Basically, MultiCfIterator behaves the same as what we described in https://github.com/facebook/rocksdb/wiki/Prefix-Seek#manual-prefix-iterating - "RocksDB will not return error when it is misused and the iterating result will be undefined."

Fix manual flush hanging on waiting for no stall for UDT in memtable … (#12771)
Summary: This PR fix a possible manual flush hanging scenario because of its expectation that others will clear out excessive memtables was not met. The root cause is the FlushRequest rescheduling logic is using a stricter criteria for what a write stall is about to happen means than `WaitUntilFlushWouldNotStallWrites` does. Currently, the former thinks a write stall is about to happen when the last memtable is half full, and it will instead reschedule queued FlushRequest and not actually proceed with the flush. While the latter thinks if we already start to use the last memtable, we should wait until some other background flush jobs clear out some memtables before proceed this manual flush. If we make them use the same criteria, we can guarantee that at any time when`WaitUntilFlushWouldNotStallWrites` is waiting, it's not because the rescheduling logic is holding it back.

Change the behavior of manual flush to not retain UDT (#12737)
Summary: When user-defined timestamps in Memtable only feature is enabled, all scheduled flushes go through a check to see if it's eligible to be rescheduled to retain user-defined timestamps. However when the user makes a manual flush request, their intention is for all the in memory data to be persisted into SST files as soon as possible. These two sides have some conflict of interest, the user can implement some workaround like https://github.com/facebook/rocksdb/issues/12631 to explicitly mark which one takes precedence. The implementation for this can be nuanced since the user needs to be aware of all the scenarios that can trigger a manual flush and handle the concurrency well etc. In this PR, we updated the default behavior to give manual flush precedence when it's requested. The user-defined timestamps rescheduling mechanism is turned off when a manual flush is requested. Likewise, all error recovery triggered flushes skips the rescheduling mechanism too.

Propagate more ReadOptions to ApproximateOffsetOf/Sizes (#12764)
Summary: Unknown why these would ignore options like deadline and read_tier. Setting total_order_seek=true is unnecessary because of the disable_prefix_seek (= true) parameter to NewIndexIterator. This is only used by the hash index, which uses total order seek if either the ReadOption or the parameter is true. The parameter is arguably redundant with the total_order_seek option, meaning it could be eliminated, but I think this case is exceptional (compared to e.g. no_io): * Prefix seek is particular to user iterators, though might be usable, carefully, for other read operations. * The historical default of total_order_seek=false in a sense is "wrong result by default" so cannot be interpreted as an intent to force prefix seek in an operation for which it might be usual or give bad results. Also added a generic release note to cover this and related PRs.

Eliminate some parameters redundant with ReadOptions (#12761)
Summary: ... in Index and CompressionDict readers (Filters in another PR). no_io and verify_checksums should be inferred from ReadOptions rather than specified redundantly. Fixes incomplete propagation of ReadOptions in UncompressionDictReader::GetOrReadUncompressionDictionar so is technically a functional change. (Related to https://github.com/facebook/rocksdb/issues/12757) Also there was hardcoded no verify_checksums in DumpTable, but only for UncompressionDict, which doesn't make sense. Now using consistent ReadOptions and verify_checksum can be controlled for more reads together.

Fix manual WAL flush causing false-positive inconsistent values in TestBackupRestore() (#12758)
Summary: **Context/Summary:** When manual WAL flush is used, the following can happen: t1: Issued Put(k1) to original DB. It entered WAL buffer since manual_wal_flush_one_in > 0. 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.

Ensure Close() before LinkFile() for WALs in Checkpoint (#12734)
Summary: POSIX semantics for LinkFile (hard links) allow linking a file that is still being written two, with both the source and destination showing any subsequent writes to the source. This may not be practical semantics for some FileSystem implementations such as remote storage. They might only link the flushed or sync-ed file contents at time of LinkFile, or might even have undefined behavior if LinkFile is called on a file still open for write (not yet "sealed"). This change builds on https://github.com/facebook/rocksdb/issues/12731 to bring more hygiene to our handling of WAL files in Checkpoint. Specifically, we now Close WAL files as soon as they are either (a) inactive and fully synced, or (b) inactive and obsolete (so maybe never fully synced), rather than letting Close() happen in handling obsolete files (maybe a background thread). This should not be a performance issue as Close() should be trivial cost relative to other IO ops, but just in case: * We don't Close() while holding a mutex, to avoid blocking, and * The old behavior is available with a new kill switch option `background_close_inactive_wals`. Stacked on https://github.com/facebook/rocksdb/issues/12731 Pull Request resolved: https://github.com/facebook/rocksdb/pull/12734 Test Plan: Extended existing unit test, especially adding a hygiene check to FaultInjectionTestFS to detect LinkFile() on a file still open for writes. FaultInjectionTestFS already has relevant tracking data, and tests can opt out of the new check, as in a smoke test I have left for the old, deprecated functionality `background_close_inactive_wals=true`. Also ran lengthy blackbox_crash_test to ensure the hygiene check is OK with the crash test. (The only place I can find we use LinkFile in production is Checkpoint.)

Fix a failure to propagate ReadOptions (#12757)
Summary: The crash test revealed a case in which the uncache functionality in ~BlockBasedTableReader could initiate an block read (IO), despite setting ReadOptions::read_tier = kBlockCacheTier. The root cause is a place in the code where many people have over time decided to opt-in propagating ReadOptions and no one took the initiative to propagate ReadOptions by default (opt out / override only as needed). The fix is in partitioned_index_reader.cc. Here, ReadOptions::readahead_size is opted-out to avoid churn in prefetch_test that is not clearly an improvement or regression. It's hard to tell given the poor state of relevant documentation https://github.com/facebook/rocksdb/issues/12756. The affected unit test was added in https://github.com/facebook/rocksdb/issues/10602. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12757 Test Plan: (Now postponed to a follow-up diff) I have added some new infrastructure to DEBUG builds to catch this specific kind of violation in unit tests and in the stress/crash test. `EnforceReadOpts` establishes a thread-local context under which we assert no IOs are performed if ReadOptions said it should be forbidden. With this new checking, the Uncache unit test would catch the critical step toward a violation (inner ReadOptions allowing IO, even if no IO is actually performed), which is fixed with the production code change.

Disable "uncache" behavior in DB shutdown (#12751)
Summary: Crash test showed a potential use-after-free where a file marked as obsolete and eligible for uncache on destruction is destroyed in the VersionSet destructor, which only happens as part of DB shutdown. At that point, the in-memory column families have already been destroyed, so attempting to uncache could use-after-free on stuff like getting the `user_comparator()` from the `internal_comparator()`. I attempted to make it smarter, but wasn't able to untangle the destruction dependencies in a way that was safe, understandable, and maintainable. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12751 Test Plan: Reproduced by adding uncache_aggressiveness to an existing (but otherwise unrelated) test. This makes it a fair regression test. Also added testing to ensure that trivial moves and DB close & reopen are well behaved with uncache_aggressiveness. Specifically, this issue doesn't seem to be because things are uncached inappropriately in those cases.
