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` Pull Request resolved: https://github.com/facebook/rocksdb/pull/12398 Test Plan: Auto tests Reviewed By: hx235 Differential Revision: D54382532 Pulled By: jowlyzhang fbshipit-source-id: e7d5b40f9b113b60e5a503558c181f080b9d02fa |

Decouple `RateLimiter` burst size and refill period (#12379)
Summary: When the rate limiter does not have any waiting requests, the first request to arrive may consume all of the available bandwidth, despite potentially having lower priority than requests that arrive later in the same refill interval. Then, those higher priority requests must wait for a refill. So even in scenarios in which we have an overall bandwidth surplus, the highest priority requests can be sporadically delayed up to a whole refill period. Alone, this isn't necessarily problematic as the refill period is configurable via `refill_period_us` and can be tuned down as needed until the max sporadic delay is tolerable. However, tuning down `refill_period_us` had a side effect of reducing burst size. Some users require a certain burst size to issue optimal I/O sizes to the underlying storage system. To satisfy those users, this PR decouples the refill period from the burst size. That way, the max sporadic delay can be limited without impacting I/O sizes issued to the underlying storage system. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12379 Test Plan: The goal is to show we can now limit the max sporadic delay without impacting compaction's I/O size. The benchmark runs compaction with a large I/O size, while user reads simultaneously run at a low rate that does not consume all of the available bandwidth. The max sporadic delay is measured using the P100 of rocksdb.file.read.get.micros. I just used strace to verify the compaction reads follow `rate_limiter_single_burst_bytes` Setup: `./db_bench -benchmarks=fillrandom,flush -write_buffer_size=67108864 -disable_auto_compactions=true -value_size=256 -num=1048576` Benchmark: `./db_bench -benchmarks=readrandom -use_existing_db=true -num=1048576 -duration=10 -benchmark_read_rate_limit=4096 -rate_limiter_bytes_per_sec=67108864 -rate_limiter_refill_period_us=$refill_micros -rate_limiter_single_burst_bytes=16777216 -rate_limit_bg_reads=true -rate_limit_user_ops=true -statistics=true -cache_size=0 -stats_level=5 -compaction_readahead_size=16777216 -use_direct_reads=true` Results: refill_micros | rocksdb.file.read.get.micros (P100) -- | -- 10000 | 10802 100000 | 100240 1000000 | 922061 For verifying compaction read sizes: `strace -fye pread64 ./db_bench -benchmarks=compact -use_existing_db=true -rate_limiter_bytes_per_sec=67108864 -rate_limiter_refill_period_us=$refill_micros -rate_limiter_single_burst_bytes=16777216 -rate_limit_bg_reads=true -compaction_readahead_size=16777216 -use_direct_reads=true` Reviewed By: hx235 Differential Revision: D54165675 Pulled By: ajkr fbshipit-source-id: c5968486316cbfb7ff8e5b7d75d3589883dd1105 |

Prefer static_cast in place of most reinterpret_cast (#12308)
Summary: The following are risks associated with pointer-to-pointer reinterpret_cast: * Can produce the "wrong result" (crash or memory corruption). IIRC, in theory this can happen for any up-cast or down-cast for a non-standard-layout type, though in practice would only happen for multiple inheritance cases (where the base class pointer might be "inside" the derived object). We don't use multiple inheritance a lot, but we do. * Can mask useful compiler errors upon code change, including converting between unrelated pointer types that you are expecting to be related, and converting between pointer and scalar types unintentionally. I can only think of some obscure cases where static_cast could be troublesome when it compiles as a replacement: * Going through `void*` could plausibly cause unnecessary or broken pointer arithmetic. Suppose we have `struct Derived: public Base1, public Base2`. If we have `Derived*` -> `void*` -> `Base2*` -> `Derived*` through reinterpret casts, this could plausibly work (though technical UB) assuming the `Base2*` is not dereferenced. Changing to static cast could introduce breaking pointer arithmetic. * Unnecessary (but safe) pointer arithmetic could arise in a case like `Derived*` -> `Base2*` -> `Derived*` where before the Base2 pointer might not have been dereferenced. This could potentially affect performance. With some light scripting, I tried replacing pointer-to-pointer reinterpret_casts with static_cast and kept the cases that still compile. Most occurrences of reinterpret_cast have successfully been changed (except for java/ and third-party/). 294 changed, 257 remain. A couple of related interventions included here: * Previously Cache::Handle was not actually derived from in the implementations and just used as a `void*` stand-in with reinterpret_cast. Now there is a relationship to allow static_cast. In theory, this could introduce pointer arithmetic (as described above) but is unlikely without multiple inheritance AND non-empty Cache::Handle. * Remove some unnecessary casts to void* as this is allowed to be implicit (for better or worse). Most of the remaining reinterpret_casts are for converting to/from raw bytes of objects. We could consider better idioms for these patterns in follow-up work. I wish there were a way to implement a template variant of static_cast that would only compile if no pointer arithmetic is generated, but best I can tell, this is not possible. AFAIK the best you could do is a dynamic check that the void* conversion after the static cast is unchanged.

Fix a case of ignored corruption in creating backups (#12200)
Summary: We often need to read the table properties of an SST file when taking a backup. However, we currently do not check checksums for this step, and even with that enabled, we ignore failures. This change ensures we fail creating a backup if corruption is detected in that step of reading table properties. To get this working properly (with existing unit tests), we also add some temperature handling logic like already exists in BackupEngineImpl::ReadFileAndComputeChecksum and elsewhere in BackupEngine. Also, SstFileDumper needed a fix to its error handling logic. This was originally intended to help diagnose some mysterious failures (apparent corruptions) seen in taking backups in the crash test, though that is now fixed in https://github.com/facebook/rocksdb/pull/12206 Pull Request resolved: https://github.com/facebook/rocksdb/pull/12200 Test Plan: unit test added that corrupts table properties, along with existing tests Reviewed By: ajkr Differential Revision: D52520674 Pulled By: pdillinger fbshipit-source-id: 032cfc0791428f3b8147d34c7d424ab128e28f42 |

Group SST write in flush, compaction and db open with new stats (#11910)
Summary: ## Context/Summary Similar to https://github.com/facebook/rocksdb/pull/11288, https://github.com/facebook/rocksdb/pull/11444, categorizing SST/blob file write according to different io activities allows more insight into the activity. For that, this PR does the following: - Tag different write IOs by passing down and converting WriteOptions to IOOptions - Add new SST_WRITE_MICROS histogram in WritableFileWriter::Append() and breakdown FILE_WRITE_{FLUSH|COMPACTION|DB_OPEN}_MICROS Some related code refactory to make implementation cleaner: - Blob stats - Replace high-level write measurement with low-level WritableFileWriter::Append() measurement for BLOB_DB_BLOB_FILE_WRITE_MICROS. This is to make FILE_WRITE_{FLUSH|COMPACTION|DB_OPEN}_MICROS include blob file. As a consequence, this introduces some behavioral changes on it, see HISTORY and db bench test plan below for more info. - Fix bugs where BLOB_DB_BLOB_FILE_SYNCED/BLOB_DB_BLOB_FILE_BYTES_WRITTEN include file failed to sync and bytes failed to write. - Refactor WriteOptions constructor for easier construction with io_activity and rate_limiter_priority - Refactor DBImpl::~DBImpl()/BlobDBImpl::Close() to bypass thread op verification - Build table - TableBuilderOptions now includes Read/WriteOpitons so BuildTable() do not need to take these two variables - Replace the io_priority passed into BuildTable() with TableBuilderOptions::WriteOpitons::rate_limiter_priority. Similar for BlobFileBuilder. This parameter is used for dynamically changing file io priority for flush, see https://github.com/facebook/rocksdb/pull/9988?fbclid=IwAR1DtKel6c-bRJAdesGo0jsbztRtciByNlvokbxkV6h_L-AE9MACzqRTT5s for more - Update ThreadStatus::FLUSH_BYTES_WRITTEN to use io_activity to track flush IO in flush job and db open instead of io_priority ## Test ### db bench Flush ``` ./db_bench --statistics=1 --benchmarks=fillseq --num=100000 --write_buffer_size=100 rocksdb.sst.write.micros P50 : 1.830863 P95 : 4.094720 P99 : 6.578947 P100 : 26.000000 COUNT : 7875 SUM : 20377 rocksdb.file.write.flush.micros P50 : 1.830863 P95 : 4.094720 P99 : 6.578947 P100 : 26.000000 COUNT : 7875 SUM : 20377 rocksdb.file.write.compaction.micros P50 : 0.000000 P95 : 0.000000 P99 : 0.000000 P100 : 0.000000 COUNT : 0 SUM : 0 rocksdb.file.write.db.open.micros P50 : 0.000000 P95 : 0.000000 P99 : 0.000000 P100 : 0.000000 COUNT : 0 SUM : 0 ``` compaction, db oopen ``` Setup: ./db_bench --statistics=1 --benchmarks=fillseq --num=10000 --disable_auto_compactions=1 -write_buffer_size=100 --db=../db_bench Run:./db_bench --statistics=1 --benchmarks=compact --db=../db_bench --use_existing_db=1 rocksdb.sst.write.micros P50 : 2.675325 P95 : 9.578788 P99 : 18.780000 P100 : 314.000000 COUNT : 638 SUM : 3279 rocksdb.file.write.flush.micros P50 : 0.000000 P95 : 0.000000 P99 : 0.000000 P100 : 0.000000 COUNT : 0 SUM : 0 rocksdb.file.write.compaction.micros P50 : 2.757353 P95 : 9.610687 P99 : 19.316667 P100 : 314.000000 COUNT : 615 SUM : 3213 rocksdb.file.write.db.open.micros P50 : 2.055556 P95 : 3.925000 P99 : 9.000000 P100 : 9.000000 COUNT : 23 SUM : 66 ``` blob stats - just to make sure they aren't broken by this PR ``` Integrated Blob DB Setup: ./db_bench --enable_blob_files=1 --statistics=1 --benchmarks=fillseq --num=10000 --disable_auto_compactions=1 -write_buffer_size=100 --db=../db_bench Run:./db_bench --enable_blob_files=1 --statistics=1 --benchmarks=compact --db=../db_bench --use_existing_db=1 pre-PR: rocksdb.blobdb.blob.file.write.micros P50 : 7.298246 P95 : 9.771930 P99 : 9.991813 P100 : 16.000000 COUNT : 235 SUM : 1600 rocksdb.blobdb.blob.file.synced COUNT : 1 rocksdb.blobdb.blob.file.bytes.written COUNT : 34842 post-PR: rocksdb.blobdb.blob.file.write.micros P50 : 2.000000 P95 : 2.829360 P99 : 2.993779 P100 : 9.000000 COUNT : 707 SUM : 1614 - COUNT is higher and values are smaller as it includes header and footer write - COUNT is 3X higher due to each Append() count as one post-PR, while in pre-PR, 3 Append()s counts as one.

Add BackupEngine feature to exclude files (#11030)
Summary: We have a request for RocksDB to essentially support disconnected incremental backup. In other words, if there is limited or no connectivity to the primary backup dir, we should still be able to take an incremental backup relative to that primary backup dir, assuming some metadata about that primary dir is available (and obviously anticipating primary backup dir will be fully available if restore is needed). To support that, this feature allows the API user to "exclude" DB files from backup. This only applies to files that can be shared between backups (sst and blob files), and excluded files are tracked in the backup metadata sufficiently to ensure they are restored at restore time. At restore time, the user provides a set of alternate backup directories (as open BackupEngines, which can be read-only), and excluded files must be found in one of the backup directories ("included" in some backup). This feature depends on backup schema version 2 features, though schema version 2.0 support is not sufficient to read / restore a backup with exclusions. This change updates the schema version to 2.1 because of this feature, so that it's easy to recognize whether a RocksDB release supports this feature, while backups not using the feature are fully compatible with 2.0. Also in this PR: * Stacked on https://github.com/facebook/rocksdb/pull/11029 * Allow progress_callback to be empty, not just no-op function, and recover from exceptions thrown by BackupEngine callbacks. * The internal-only `AsBackupEngine()` function is working around the diamond hierarchy of `BackupEngineImplThreadSafe` to get to the internals, without using confusing features like virtual inheritance.

Allow manifest fix-up without requiring prior state (#10796)
Summary: This change is motivated by ensuring that `ldb update_manifest` or `UpdateManifestForFilesState` can run without expecting files to open when the old temperature is provided (in case the FileSystem strictly interprets non-kUnknown), but ended up fixing a problem in `OfflineManifestWriter` (used by `ldb unsafe_remove_sst_file`) where it would open some SST files during recovery and expect them to match the prior manifest state, even if not required by the intended new state. Also update BackupEngine to retry with Temperature kUnknown when reading file with potentially "wrong" temperature.

Always verify SST unique IDs on SST file open (#10532)
Summary: Although we've been tracking SST unique IDs in the DB manifest unconditionally, checking has been opt-in and with an extra pass at DB::Open time. This changes the behavior of `verify_sst_unique_id_in_manifest` to check unique ID against manifest every time an SST file is opened through table cache (normal DB operations), replacing the explicit pass over files at DB::Open time. This change also enables the option by default and removes the "EXPERIMENTAL" designation. One possible criticism is that the option no longer ensures the integrity of a DB at Open time. This is far from an all-or-nothing issue. Verifying the IDs of all SST files hardly ensures all the data in the DB is readable. (VerifyChecksum is supposed to do that.) Also, with max_open_files=-1 (default, extremely common), all SST files are opened at DB::Open time anyway. Implementation details: * `VerifySstUniqueIdInManifest()` functions are the extra/explicit pass that is now removed. * Unit tests that manipulate/corrupt table properties have to opt out of this check, because that corrupts the "actual" unique id. (And even for testing we don't currently have a mechanism to set "no unique id" in the in-memory file metadata for new files.) * A lot of other unit test churn relates to (a) default checking on, and (b) checking on SST open even without DB::Open (e.g. on flush) * Use `FileMetaData` for more `TableCache` operations (in place of `FileDescriptor`) so that we have access to the unique_id whenever we might need to open an SST file. **There is the possibility of performance impact because we can no longer use the more localized `fd` part of an `FdWithKeyRange` but instead follow the `file_metadata` pointer. However, this change (possible regression) is only done for `GetMemoryUsageByTableReaders`.** * Removed a completely unnecessary constructor overload of `TableReaderOptions` Possible follow-up: * Verification only happens when opening through table cache. Are there more places where this should happen? * Improve error message when there is a file size mismatch vs. manifest (FIXME added in the appropriate place). * I'm not sure there's a justification for `FileDescriptor` to be distinct from `FileMetaData`. * I'm skeptical that `FdWithKeyRange` really still makes sense for optimizing some data locality by duplicating some data in memory, but I could be wrong. * An unnecessary overload of NewTableReader was recently added, in the public API nonetheless (though unusable there). It should be cleaned up to put most things under `TableReaderOptions`.

Don't wait for indirect flush in read-only DB (#10569)
Summary: Some APIs for getting live files, which are used by Checkpoint and BackupEngine, can optionally trigger and wait for a flush. These would deadlock when used on a read-only DB. Here we fix that by assuming the user wants the overall operation to succeed and is OK without flushing (because the DB is read-only). Follow-up work: the same or other issues can be hit by directly invoking some DB functions that are clearly not appropriate for read-only instance, but are not covered by overrides in DBImplReadOnly and CompactedDBImpl. These should be fixed to avoid similar problems on accidental misuse. (Long term, it would be nice to have a DBReadOnly class without those members, like BackupEngineReadOnly.)

Do not hold mutex when write keys if not necessary (#7516)
Summary: ## Problem Summary RocksDB will acquire the global mutex of db instance for every time when user calls `Write`. When RocksDB schedules a lot of compaction jobs, it will compete the mutex with write thread and it will hurt the write performance. ## Problem Solution: I want to use log_write_mutex to replace the global mutex in most case so that we do not acquire it in write-thread unless there is a write-stall event or a write-buffer-full event occur.

Expose the initial logger creation error (#10223)
Summary: https://github.com/facebook/rocksdb/issues/9984 changes the behavior of RocksDB: if logger creation failed during `SanitizeOptions()`, `DB::Open()` will fail. However, since `SanitizeOptions()` is called in `DBImpl::DBImpl()`, we cannot directly expose the error to caller without some additional work. This is a first version proposal which: - Adds a new member `init_logger_creation_s` to `DBImpl` to store the result of init logger creation - Checks the error during `DB::Open()` and return it to caller if non-ok This is not very ideal. We can alternatively move the logger creation logic out of the `SanitizeOptions()`. Since `SanitizeOptions()` is used in other places, we need to check whether this change breaks anything in case other callers of `SanitizeOptions()` assumes that a logger should be created.

Use SpecialEnv to speed up some slow BackupEngineRateLimitingTestWithParam (#9974)
Summary: **Context:** `BackupEngineRateLimitingTestWithParam.RateLimiting` and `BackupEngineRateLimitingTestWithParam.RateLimitingVerifyBackup` involve creating backup and restoring of a big database with rate-limiting.

Remove own ToString() (#9955)
Summary: ToString() is created as some platform doesn't support std::to_string(). However, we've already used std::to_string() by mistake for 16 months (in db/db_info_dumper.cc). This commit just remove ToString().

Use std::numeric_limits<> (#9954)
Summary: Right now we still don't fully use std::numeric_limits but use a macro, mainly for supporting VS 2013. Right now we only support VS 2017 and up so it is not a problem. The code comment claims that MinGW still needs it. We don't have a CI running MinGW so it's hard to validate. since we now require C++17, it's hard to imagine MinGW would still build RocksDB but doesn't support std::numeric_limits<>.

Fix remaining uses of "backupable" (#9792)
Summary: Various renaming and fixes to get rid of remaining uses of "backupable" which is terminology leftover from the original, flawed design of BackupableDB. Now any DB can be backed up, using BackupEngine.
