As title, Closes https://github.com/facebook/rocksdb/issues/9272
Since TimestampAssigner-related classes needs to access
`WriteBatch::ProtectionInfo` objects which is for internal use only,
it's difficult to make `AssignTimestamp` methods a template and put them
in the same public header, `include/rocksdb/write_batch.h`.

- Move thread 2's work into current thread to avoid half of the thread creation cuz there is no difference in doing so. We expect this can make the thread-creation error less often, even though we can't gurantee it from happening again. Considering this is a trivial change with positive impact, it's still worth landing and monitor if it's enough to solve the problem in reality.

Summary:
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9266
This diff adds a new tag `CommitWithTimestamp`. Currently, there is no API to trigger writing
this tag to WAL, thus it is unavailable to users.
This is an ongoing effort to add user-defined timestamp support to write-committed transactions.
This diff also indicates all column families that may potentially participate in the same
transaction must either disable timestamp or have the same timestamp format, since
`CommitWithTimestamp` tag is followed by a single byte-array denoting the commit
timestamp of the transaction. We will enforce this checking in a future diff. We keep this
diff small.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9240
Test Plan:
tests enhanced to cover more cases etc.
Extreme case performance testing indicates small % regression in fillseq (w/ compaction), though CPU profile etc. doesn't suggest any explanation. There is enhanced correctness checking in Footer::DecodeFrom, but this should be negligible.
TEST_TMPDIR=/dev/shm/ ./db_bench -benchmarks=fillseq -memtablerep=vector -allow_concurrent_memtable_write=false -num=30000000 -checksum_type=1 --disable_wal={false,true}
(Each is ops/s averaged over 50 runs, run simultaneously with competing configuration for load fairness)
Before w/ wal: 454512
After w/ wal: 444820 (-2.1%)
Before w/o wal: 1004560
After w/o wal: 998897 (-0.6%)
Since this doesn't modify WAL code, one would expect real effects to be larger in w/o wal case.
This regression will be corrected in a follow-up PR.

Previously, the OnErrorRecoveryCompleted callback was called when
RocksDB was able to successfully recover from a retryable error.
However, if the recovery failed and was eventually stopped, there was no

is introduced that deprecates the OnErrorRecoveryCompleted callback. The
new callback is called with the original error and the new error status.

Summary:
**Context:**
Searching `TableProperties::properties_offsets` across the codebase reveals that internally it is only used to find the external SST file's global seqno offeset. Therefore we can narrow it down and replace this map property with a uint64_t property `external_sst_file_global_seqno_offset` to save memory usage related to table properties.
Note:
- See PR comments for discussion about potential impact on existing external usage of `TableProperties::properties_offsets`
- See PR comments for discussion on keeping external SST file global seqno's offset VS using a simple flag indicating seqno's existence.
**Summary:**
- Replaced `TableProperties::properties_offsets` with `TableProperties::external_sst_file_global_seqno_offset`
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9212
Test Plan: - Relied on existing tests should be sufficient since `TableProperties::properties_offsets` existed before and should already be tested.

Summary:
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9205
Update WriteBatch::AssignTimestamp() APIs so that they take an
additional argument, i.e. a function object called `checker` indicating the user-specified logic of performing
checks on timestamp sizes.
WriteBatch is a building block used by multiple other RocksDB components, each of which may track
timestamp information in different data structures. For example, transaction can either write to
`WriteBatchWithIndex` which is a `WriteBatch` with index, or write directly to raw `WriteBatch` if
`Transaction::DisableIndexing()` is called.
`WriteBatchWithIndex` keeps mapping from column family id to comparator, and transaction needs
to keep similar information for the `WriteBatch` if user calls `Transaction::DisableIndexing()` (dynamically)
so that we will know the size of each timestamp later. The bookkeeping info maintained by `WriteBatchWithIndex`
and `Transaction` should not overlap.
When we later call `WriteBatch::AssignTimestamp()`, we need to use these data structures to guarantee
that we do not accidentally assign timestamps for keys from column families that disable timestamp.

path of librocksdb only. This patch allows plugin dependencies to be declared in

StressTest() constructor deletes the directory "dbstress" because
the option --destroy_db_initially is true by default in db_stress.
This Seg fault happens on a new database, UniqueIdVerifier's constructor
tries to read the ".unique_ids" file, if the file is not present,
ReopenWritableFile() tries to create .unique_ids file, but fails
as the directory db_stress is not available. The data_file_writer_
is set as an invalid(null) pointer and in subsequent calls (~UniqueIdVerifier()
and UniqueIdVerifier::Verify()) it accesses this null pointer and crashes.
This patch creates db_stress directory if it is missing, so the .unique_ids file
is created.

deletions are completed. Two fixes related to this:
* There was a gap in several places between decrementing
pending_purge_obsolete_files_ and incrementing bg_purge_scheduled_ where
the db mutex would be released and GetSortedWalFiles (and others) could
get false information that no deletions are pending.
* The fix to https://github.com/facebook/rocksdb/issues/8591 (disabling deletions in GetSortedWalFiles) seems
incomplete because it doesn't prevent pending deletions from occuring
during the operation (if deletions not already disabled, the case that
was to be fixed by the change).

Test Plan:
existing tests (it's hard to write a test for interleavings
that are now excluded - this is what stress test is for)

Summary:
* added missing override specifiers for overriden methods
this fixes compiler warnings emitted by g++ and clang++ when compile option `-Wsuggest-override` is turned on.
* fix compile warning with -Wmaybe-uninitialized
g++-11 warns about a _potentially_ uninitialized variable when using `-Wmaybe_uninitialized`:
```

Summary:
More follow-up to https://github.com/facebook/rocksdb/issues/9193 + https://github.com/facebook/rocksdb/issues/9188
* Even though we need to print ETA updates to avoid hitting the 10min
timeout, we need to avoid printing an update if there's no actual
progress, so that hung tests will timeout after 10 min rather than 5
hours.
* When there is a hung test, it's really annoying to track down which
test is hung, so if no progress is observed for 1 minute, we run ps once
to show what is running.

Summary:
Printing file checksum (usually an integer) in non-hex format is barely useful. To make the matter
worse, it can mess with the output format. If you use `less` to redirect the output of `ldb manifest_dump`,
non-hex file checksum can cause `less` not to function as expected.
Also output some additional fields to json output.

Test Plan: manually test `ldb manifest_dump`.

Summary:
Address some issues with https://github.com/facebook/rocksdb/issues/9188
* Internal CI doesn't render \r as anything, so use \n for "not
connected to terminal" case
* CircleCI apparently uses a pseudo-tty for output and although
rerdirect stdout (because of EAGAIN bug) we don't redirect stderr, so it
is detected as a terminal-connected case. Fix by redirecting stderr
also.

Summary:
Original unit test fail to test the case of multi-cf mode switching to new manifest. The assertion
failure will trigger when the primary instance reopens and secondary continues to tail the
newly-created MANIFEST. Fix the assertion failure and update existing unit tests.
