Summary: In Linux, when reopening DB with many SST files, profiling shows that 100% system cpu time spent for a couple of seconds for `GetLogicalBufferSize`. This slows down MyRocks' recovery time when site is down. This PR introduces two new APIs: 1. `Env::RegisterDbPaths` and `Env::UnregisterDbPaths` lets `DB` tell the env when it starts or stops using its database directories . The `PosixFileSystem` takes this opportunity to set up a cache from database directories to the corresponding logical block sizes. 2. `LogicalBlockSizeCache` is defined only for OS_LINUX to cache the logical block sizes. Other modifications: 1. rename `logical buffer size` to `logical block size` to be consistent with Linux terms. 2. declare `GetLogicalBlockSize` in `PosixHelper` to expose it to `PosixFileSystem`. 3. change the functions `IOError` and `IOStatus` in `env/io_posix.h` to have external linkage since they are used in other translation units too. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6457 Test Plan: 1. A new unit test is added for `LogicalBlockSizeCache` in `env/io_posix_test.cc`. 2. A new integration test is added for `DB` operations related to the cache in `db/db_logical_block_size_cache_test.cc`. `make check` Differential Revision: D20131243 Pulled By: cheng-chang fbshipit-source-id: 3077c50f8065c0bffb544d8f49fb10bba9408d04

Summary: When users fail to open a DB with file lock failure, it is sometimes hard for users to debug. We now include the time the lock is acquired and the thread ID that acquired the lock, to help users debug problems like this. Default Env's thread ID is used. Since type of lockedFiles is changed, rename it to follow naming convention too.

Summary: It's never too soon to refactor something. The patch splits the recently introduced (`VersionEdit` related) `BlobFileState` into two classes `BlobFileAddition` and `BlobFileGarbage`. The idea is that once blob files are closed, they are immutable, and the only thing that changes is the amount of garbage in them. In the new design, `BlobFileAddition` contains the immutable attributes (currently, the count and total size of all blobs, checksum method, and checksum value), while `BlobFileGarbage` contains the mutable GC-related information elements (count and total size of garbage blobs). This is a better fit for the GC logic and is more consistent with how SST files are handled.

Summary: Allow user to specify options.max_open_files != -1 with FIFO compaction. If max_open_files != -1, not all table files are kept open. In the past, FIFO style compaction requires all table files to be open in order to read file creation time from table properties. Later, we added file creation time to MANIFEST, making it possible to read file creation time without opening file.

Summary: `TruncateLastLogAfterRecoverWithoutFlush` case depends on fallocate support of underlying file system. On a file system which lacks of this feature, like zfs, it will fail to allocate predefined file size as this test case intends to do; So a check block is added to detect fallocate support and skip test if not.

Summary: In CompactRange, if there is no key in memtable falling in the specified range, then flush is skipped. This PR extends this skipping logic to SST file levels: it starts compaction from the highest level (starting from L0) that has files with key falling in the specified range, instead of always starts from L0. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6482 Test Plan: A new test ManualCompactionTest::SkipLevel is added. Also updated a test related to statistics of index block cache hit in db_test2, the index cache hit is increased by 1 in this PR because when checking overlap for the key range in L0, OverlapWithLevelIterator will do a seek in the table cache iterator, which will read from the cached index. Also updated db_compaction_test and db_test to use correct range for full compaction.

Summary: Today `WriteUnpreparedTxn::RollbackInternal` will write the rollback batch assuming that there is only a single subbatch. However, because untracked_keys_ are currently not deduplicated, it's possible for duplicate keys to exist, and thus split the batch. Also, tracked_keys_ also does not support compators outside of the bytewise comparators, so it's possible for duplicates to occur there as well. To solve this, just pass in the correct subbatch count. Also, removed `WriteUnpreparedRollbackPreReleaseCallback` to unify the Commit/Rollback codepaths some more. Also, fixed a bug in `CommitInternal` where if 1. two_write_queue is true and 2. include_data is true, then `WriteUnpreparedCommitEntryPreReleaseCallback` ends up calling `AddCommitted` on the commit time write batch a second time on the second write. To fix, `WriteUnpreparedCommitEntryPreReleaseCallback` is re-initialized.

Summary: Add some flags for configuring an SstFileManager. An SstFileManager is only created when one or more of these flags are set. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6454 Test Plan: - ran it a while: ``` $ python ./tools/db_crashtest.py blackbox --simple -max_key=100000 -write_buffer_size=131072 -target_file_size_base=131072 -max_bytes_for_level_base=524288 -value_size_mult=33 --interval=10 -max_background_compactions=4 -max_background_flushes=2 -sst_file_manager_bytes_per_sec=1048576 ``` - verified with strace the SstFileManager is behaving as configured: ``` $ strace -fp `pidof db_stress` -e ftruncate,unlink ...

Summary: Original author: jeffrey-xiao If we are writing a global seqno for an ingested file, the range tombstone metablock gets accessed and put into the cache during ingestion preparation. At the time, the global seqno of the ingested file has not yet been determined, so the cached block will not have a global seqno. When the file is ingested and we read its range tombstone metablock, it will be returned from the cache with no global seqno. In that case, we use the actual seqnos stored in the range tombstones, which are all zero, so the tombstones cover nothing. This commit removes global_seqno_ variable from Block. When iterating over a block, the global seqno for the block is determined by the iterator instead of storing this mutable attribute in Block. Additionally, this commit adds a regression test to check that keys are deleted when ingesting a file with a global seqno and range deletion tombstones.

Summary: BlobDB currently does not keep track of blob files: no records are written to the manifest when a blob file is added or removed, and upon opening a database, the list of blob files is populated simply based on the contents of the blob directory. This means that lost blob files cannot be detected at the moment. We plan to solve this issue by making blob files a part of `Version`; as a first step, this patch makes it possible to store information about blob files in `VersionEdit`. Currently, this information includes blob file number, total number and size of all blobs, and total number and size of garbage blobs. However, the format is extensible: new fields can be added in both a forward compatible and a forward incompatible manner if needed (similarly to `kNewFile4`).

Summary: The logic that handles io_uring partial results was wrong. Fix the logic by putting it into a queue and continue reading. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6441 Test Plan: Make sure this patch fixes the application test case where the bug was discovered; in env_test, add a unit test that simulates partial results and make sure the results are still correct.
