5746767387 add ldb unsafe_remove_sst_file subcommand (#7335)
Summary:
This is adapted from https://github.com/facebook/rocksdb/issues/6678 but takes a different approach, avoiding opening a read-write DB and avoiding the `DeleteFile()` API.

First, this PR refactors how options variables are initialized in `ldb` so it can be reused in a subcommand that doesn't open a DB:

- Separated remaining option initialization logic out of `OpenDB()`. The new `PrepareOptions()` function initializes the full options state.
- Fixed an old TODO about applying the subcommand CF option overrides to the proper `ColumnFamilyOptions` object.

Second, this PR adds the `ldb unsafe_remove_sst_file` subcommand. It uses the `VersionSet`-level APIs to remove the file with the specified number.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7335

Test Plan: played with interactive python and this file removal command. Verified openability/correct results in case of multiple column families, multiple levels, etc.

af54c4092a fix SstFileWriter with dictionary compression (#7323)
Summary:
In block-based table builder, the cut-over from buffered to unbuffered
mode involves sampling the buffered blocks and generating a dictionary.
There was a bug where `SstFileWriter` passed zero as the `target_file_size`
causing the cutover to happen immediately, so there were no samples
available for generating the dictionary.

This PR changes the meaning of `target_file_size == 0` to mean buffer
the whole file before cutting over. It also adds dictionary compression
support to `sst_dump --command=recompress` for easy evaluation.

d0c1a01c1b Avoid converting MERGES to PUTS when allow_ingest_behind is true (#7166)
Summary:
- Closes https://github.com/facebook/rocksdb/issues/6490
- Currently MERGEs are converted to PUTs at bottom or compaction has reached the beginning of the key, this can wrongly cover a PUT future base case.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7166

Test Plan:
- Automated: `make all check`
- Manual: With `allow_ingest_behind = true`, add Merge operations to a key then run compaction. Then run ingesting external files to make sure the base case is probably compacted with existing Merges.

c4d8838a2b New bit manipulation functions and 128-bit value library (#7338)
Summary:
These new functions and 128-bit value bit operations are
expected to be used in a forthcoming Bloom filter alternative.

No functional changes to production code, just new code only called by
unit tests, cosmetic changes to existing headers, and fix an existing
function for a yet-unused template instantiation (BitsSetToOne on
something signed and smaller than 32 bits).

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7338

Test Plan:
Unit tests included. Works with and without
TEST_UINT128_COMPAT=1 to check compatibility with and without
__uint128_t. Also added that parameter to the CircleCI build
build-linux-shared_lib-alt_namespace-status_checked.

177f8bd063 Bound L0->Lbase fanout in dynamic leveled compaction (#7325)
Summary:
L0 score is based on size target and number of files. The size target
used is `max_bytes_for_level_base`. However, the base level's size can
dynamically expand in write burst mode. In fact, it can expand so much
that L0->Lbase becomes the highest fanout in target sizes. This doesn't
make sense from an efficiency perspective, so this PR bounds the
L0->Lbase fanout to the smoothed level multiplier. The L0 scoring based
on file count remains unchanged.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7325

Test Plan:
contrived benchmark that exhibits the problem:

```
$ TEST_TMPDIR=/data/users/andrewkr/ ./db_bench -benchmarks=filluniquerandom,readrandom -write_buffer_size=1048576 -target_file_size_base=1048576 -max_bytes_for_level_base=4194304 -level0_file_num_compaction_trigger=4 -level_compaction_dynamic_level_bytes=true -compression_type=none -max_background_jobs=12 -rate_limiter_bytes_per_sec=104857600 -benchmark_write_rate_limit=10485760 -num=100000000
```

Results:

- "Burst W-Amp" is the write-amp near the end of the fillrandom benchmark
- "Total W-Amp" is the write-amp after readrandom has run a while and all levels no longer need compaction

Branch | Burst W-Amp | Total W-Amp | fillrandom (MB/s)

5043960623 Add a blob file builder class that can be used in background jobs (#7306)
Summary:
The patch adds a class called `BlobFileBuilder` that can be used to build
and cut blob files in background jobs (flushes/compactions). The class
enforces a value size threshold (`min_blob_size`; smaller blobs will be inlined
in the LSM tree itself), and supports specifying a blob file size limit (`blob_file_size`),
as well as compression (`blob_compression_type`) and checksums for blob files.
It also keeps track of the generated blob files and their associated `BlobFileAddition`
metadata, which can be applied as part of the background job's `VersionEdit`.

    This new object wraps FSRandomAccessFile pointer.

    Objective: If tracing is enabled, FSRandomAccessFile Ptr returns
    FSRandomAccessFileTracingWrapper pointer that includes all necessary
    information in IORecord and calls underlying FileSystem and invokes
    IOTracer to dump that record in a binary file. If tracing is disabled
    then, underlying FileSystem pointer is returned directly.
    FSRandomAccessFilePtr wrapper class is added to bypass the FSRandomAccessFileWrapper when
    tracing is disabled.

9aad24da55 Real fix for race in backup custom checksum checking (#7309)
Summary:
This is a "real" fix for the issue worked around in https://github.com/facebook/rocksdb/issues/7294.
To get DB checksum info for live files, we now read the manifest file
that will become part of the checkpoint/backup. This requires a little
extra handling in taking a custom checkpoint, including only reading the
manifest file up to the size prescribed by the checkpoint.

This moves GetFileChecksumsFromManifest from backup code to
file_checksum_helper.{h,cc} and removes apparently unnecessary checking
related to column families.

Updated HISTORY.md and warned potential future users of
DB::GetLiveFilesChecksumInfo()

416943bf28 Eliminates a no-op compaction upon snapshot release when disabling auto compactions (#7267)
Summary:
After releasing a snapshot, it checks whether it is suitable to trigger bottom compactions.
When disabling auto compactions, it may still schedule compaction when releasing a snapshot. Whereas no compaction job will be actually handled, so the state of LSM is not changed and compaction will be triggered again and again every time releasing a snapshot.

Too frequent compactions lead to high CPU usage and high db_mutex lock contention which affects foreground write duration finally.

a1b5484811 Work around a backup bug with DB custom checksums (#7294)
Summary:
On a read-write DB configured with
DBOptions::file_checksum_gen_factory, BackupEngine::CreateNewBackup can
fail intermittently, with non-OK status. This is due to a race between
GetLiveFiles and GetLiveFilesChecksumInfo in creating backups.

For patching 6.12 release (as this commit is intended for, except this is a
forward-merged version), we can simply treat files for which we falsely failed
to get checksum info as legacy files lacking checksum info.

Summary:
This test uses database functionality and required more extensive work to get it to pass than the other tests.  The DB functionality required for this test now passes the check.

When it was unclear what the proper behavior was for unchecked status codes, a TODO was added.

cc24ac14eb Store FSSequentialFilePtr object in SequenceFileReader (#7190)
Summary:
This diff contains following changes:
    1. Replace `FSSequentialFile` pointer with `FSSequentialFilePtr` object that wraps `FSSequentialFile` pointer in `SequenceFileReader`.

Objective: If tracing is enabled, `FSSequentialFilePtr` returns `FSSequentialFileTracingWrapper` pointer that includes all necessary information in `IORecord` and calls underlying FileSystem and invokes `IOTracer` to dump that record in a binary file. If tracing is disabled then, underlying `FileSystem` pointer is returned directly. `FSSequentialFilePtr` wrapper class is added to bypass the `FSSequentialFileTracingWrapper` when tracing is disabled.

5d5ff82408 Disable recycle_log_file_num with kTolerateCorruptedTailRecords (#7271)
Summary:
The two features are naturally incompatible. WAL recycling expects the recovery to succeed upon encountering a corrupt record at the point where new data ends and recycled data remains at the tail. However, `WALRecoveryMode::kTolerateCorruptedTailRecords` must fail upon encountering any such corrupt record, as it cannot differentiate between this and a real corruption, which would cause committed updates to be truncated.
