Summary:
PR https://github.com/facebook/rocksdb/issues/9888 started to enforce the contract of single delete described in https://github.com/facebook/rocksdb/wiki/Single-Delete.
For some of existing use cases, it is desirable to have a transition during which compaction will not fail
if the contract is violated. Therefore, we add a temporary option `enforce_single_del_contracts` to allow
application to opt out from this new strict behavior. Once transition completes, the flag can be set to `true` again.
In a future release, the option will be removed.

Summary:
**Context:**
`BackupEngineRateLimitingTestWithParam.RateLimiting` and `BackupEngineRateLimitingTestWithParam.RateLimitingVerifyBackup` involve creating backup and restoring of a big database with rate-limiting. Using the normal env with a normal clock requires real elapse of time (13702 - 19848 ms/per test). As suggested in https://github.com/facebook/rocksdb/pull/8722#discussion_r703698603, this PR is to speed it up with SpecialEnv (`time_elapse_only_sleep=true`) where its clock accepts fake elapse of time during rate-limiting (100 - 600 ms/per test)
**Summary:**
- Added TEST_ function to set clock of the default rate limiters in backup engine
- Shrunk testdb by 10 times while keeping it big enough for testing
- Renamed some test variables and reorganized some if-else branch for clarity without changing the test
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9974

- Run tests pre/post PR the same time to verify the tests are sped up by 90 - 95%

Summary:
These methods allow for more thorough testing of the ObjectRegistry and Customizable infrastructure in a simpler manner. With this change, the Customizable tests can now check what factories are registered and attempt to create each of them in a systematic fashion.
With this change, I think all of the factories registered with the ObjectRegistry/CreateFromString are now tested via the customizable_test classes.
Note that there were a few other minor changes. There was a "posix://*" register with the ObjectRegistry which was missed during the PatternEntry conversion -- these changes found that. The nickname and default names for the FileSystem classes was also inverted.

Summary:
This PR
- since we are testing with disable_wal = true and best_efforts_recovery, we should set column family count to 1, due to the requirement of `ExpectedState` tracking and replaying logic.
- during backup and checkpoint restore, disable best-efforts-recovery. This does not matter now because db_crashtest.py always disables wal when testing best-efforts-recovery. In the future, if we enable wal, then not setting `restore_opitions.best_efforts_recovery` will cause backup db not to recover the WALs, and differ from db (that enables WAL).
- during verification of backup and checkpoint restore, print the key where inconsistency exists between expected state and db.

Add methods to set the various functions (Parse, Serialize, Equals) to the OptionTypeInfo. These methods simplify the number of constructors required for OptionTypeInfo and make the code a little clearer.
Add functions to the OptionTypeInfo for Prepare and Validate. These methods allow types other than Configurable and Customizable to have Prepare and Validate logic. These methods could be used by an option to guarantee that its settings were in a range or that a value was initialized.

The pmem-rocksdb-plugin repo contains RocksDB’s plugins for LSM-tree based KV store to fit it on the PMEM by effectively utilize its characteristics. The first two basic plugins are:
1) Providing a filesystem API wrapper to write RocksDB's WAL (Write Ahead Log) files on PMEM to optimize write performance. 2) Using PMEM as secondary cache to optimize read performance.

Summary:
In case of non-TransactionDB and avoid_flush_during_recovery = true, RocksDB won't
flush the data from WAL to L0 for all column families if possible. As a
result, not all column families can increase their log_numbers, and
min_log_number_to_keep won't change.
For transaction DB (.allow_2pc), even with the flush, there may be old WAL files that it must not delete because they can contain data of uncommitted transactions and min_log_number_to_keep won't change.
If we persist a new MANIFEST with
advanced log_numbers for some column families, then during a second
crash after persisting the MANIFEST, RocksDB will see some column
families' log_numbers larger than the corrupted WAL, and the "column family inconsistency" error will be hit, causing recovery to fail.
This PR update unit tests to emulate the errors and tests are failing without a fix.

Both cases are parameterized by thread count (1 or 8) and merge operands per key (1, 32, or 1024). The SST file case is additionally parameterized by whether data is in block cache or mmap'd memory.

Summary:
https://github.com/facebook/rocksdb/issues/9961 broke format_compatible check because of `make clean`
referencing TEST_TMPDIR. The Makefile behavior seems reasonable to me,
so here's a fix in check_format_compatible.sh
Apparently I also included removing a redundant part of our CircleCI config.

Removing unnecessary checks around conversion from int/long to double as it does not lose information (see https://docs.oracle.com/javase/specs/jls/se9/html/jls-5.html#jls-5.1.2).
For example, `value > Double.MAX_VALUE` is always false when value is long or int.

Summary:
Having all of TMPD, TMPDIR and TEST_TMPDIR as configuration
parameters is confusing. This change simplifies a number of things by
standardizing on TEST_TMPDIR, while still recognizing the old names
also. In detail:
* crash_test.mk also needs to use TEST_TMPDIR for crash test, so put in
shared common.mk (an upgrade of python.mk)
* Always exporting TEST_TMPDIR eliminates the need to propagate TMPD or
export TEST_TMPDIR in selective places.
* Use --tmpdir option to gnu_parallel so that it doesn't need TMPDIR
environment variable
* Remove obsolete parloop and parallel_check Makefile targets
* Remove undefined, unused function ResetTmpDirForDirectIO()

Previously all fault injection was ignored in release mode. This PR adds it back except for read fault injection (`--read_fault_one_in > 0`) since its dependency (`IGNORE_STATUS_IF_ERROR`) is unavailable in release mode.
Other notable changes include:
- Moved `EnableWriteErrorInjection()` for `--write_fault_one_in > 0` so it's after `DB::Open()` without depending on `SyncPoint`
- Made `--read_fault_one_in > 0` return an error in release mode
- Updated `db_crashtest.py` to always set `--read_fault_one_in=0` in release mode

Summary:
`db_stress` already tracks expected state history to verify prefix-recoverability when `sync_fault_injection` is enabled. This PR enables `sync_fault_injection` in `db_crashtest.py`.
Previously enabling `sync_fault_injection` would cause whole unsynced files to be dropped. This PR adds a more interesting case of losing only the tail of unsynced data by implementing `TestFSWritableFile::RangeSync()` and enabling `{wal_,}bytes_per_sync`.

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<>.

Summary:
PR 9929 adds a new CompactionFilter::Decision, i.e.
kRemoveWithSingleDelete so that CompactionFilter can indicate to
CompactionIterator that a PUT can only be removed with SD. However, how
CompactionIterator handles such a key is implementation detail which
should not be implied in the public API. In fact,
such a PUT can just be dropped. This is an optimization which we will apply in the near future.

Summary:
This is inspired by debugging a regression test that runs for ~0.05 seconds and the short
running time makes it prone to variance. While db_bench ran for ~60 seconds, 59.95 seconds
was spent opening 128 databases (and doing recovery). So it was harder to notice that the
benchmark only ran for 0.05 seconds.
Normally I add output to the end of the line to make life easier for existing tools that parse it
but in this case the output near the end of the line has two optional parts and one of the optional
parts adds an extra newline.

Summary:
When a memtable is flushed and the flush would lead to a 0 byte .sst
file being created, RocksDB does not write out the empty .sst file to
disk.
However it still calls Env::DeleteFile() on the file as part of some
cleanup procedure at the end of BuildTable().
Because the to-be-deleted file does not exist, this requires
implementors of the DeleteFile() API to check if the file exists on
their own code, or otherwise risk running into PathNotFound errors when
DeleteFile is invoked on non-existing files.
This PR fixes the situation so that when no .sst file is created,
Deletefile will not be called either.
TableFileCreationStarted() will still be called as before.

Summary:
To support a project to prototype and evaluate algorithmic
enhancments and alternatives to LRUCache, here I have separated out
LRUCache into internal-only "FastLRUCache" and cut it down to
essentials, so that details like secondary cache handling and
priorities do not interfere with prototyping. These can be
re-integrated later as needed, along with refactoring to minimize code
duplication (which would slow down prototyping for now).
