629e3e1d77 Fix spelling in public API (#9490)
Summary:
I feel it would be nice if we can fix this spelling error.

In `SizeApproximationOptions`, the `include_memtabtles` should be `include_memtables`.

aae3093719 Introduce a CountedFileSystem for counting file operations (#9283)
Summary:
Added a CountedFileSystem that tracks a number of file operations (opens, closes, deletes, renames, flushes, syncs, fsyncs, reads, writes).    This class was based on the ReportFileOpEnv from db_bench.

This is a stepping stone PR to be able to change the SpecialEnv into a SpecialFileSystem, where several of the file varieties wish to do operation counting.

3122cb4358 Revise APIs related to user-defined timestamp (#8946)
Summary:
ajkr reminded me that we have a rule of not including per-kv related data in `WriteOptions`.
Namely, `WriteOptions` should not include information about "what-to-write", but should just
include information about "how-to-write".

According to this rule, `WriteOptions::timestamp` (experimental) is clearly a violation. Therefore,
this PR removes `WriteOptions::timestamp` for compliance.
After the removal, we need to pass timestamp info via another set of APIs. This PR proposes a set
of overloaded functions `Put(write_opts, key, value, ts)`, `Delete(write_opts, key, ts)`, and
`SingleDelete(write_opts, key, ts)`. Planned to add `Write(write_opts, batch, ts)`, but its complexity
made me reconsider doing it in another PR (maybe).

For better checking and returning error early, we also add a new set of APIs to `WriteBatch` that take
extra `timestamp` information when writing to `WriteBatch`es.
These set of APIs in `WriteBatchWithIndex` are currently not supported, and are on our TODO list.

Removed `WriteBatch::AssignTimestamps()` and renamed `WriteBatch::AssignTimestamp()` to
`WriteBatch::UpdateTimestamps()` since this method require that all keys have space for timestamps
allocated already and multiple timestamps can be updated.

The constructor of `WriteBatch` now takes a fourth argument `default_cf_ts_sz` which is the timestamp
size of the default column family. This will be used to allocate space when calling APIs that do not
specify a column family handle.

Also, updated `DB::Get()`, `DB::MultiGet()`, `DB::NewIterator()`, `DB::NewIterators()` methods, replacing
some assertions about timestamp to returning Status code.

920386f2b7 Detect (new) Bloom/Ribbon Filter construction corruption (#9342)
Summary:
Note: rebase on and merge after https://github.com/facebook/rocksdb/pull/9349, https://github.com/facebook/rocksdb/pull/9345, (optional) https://github.com/facebook/rocksdb/pull/9393
**Context:**
(Quoted from pdillinger) Layers of information during new Bloom/Ribbon Filter construction in building block-based tables includes the following:
a) set of keys to add to filter
b) set of hashes to add to filter (64-bit hash applied to each key)
c) set of Bloom indices to set in filter, with duplicates
d) set of Bloom indices to set in filter, deduplicated
e) final filter and its checksum

This PR aims to detect corruption (e.g, unexpected hardware/software corruption on data structures residing in the memory for a long time) from b) to e) and leave a) as future works for application level.
- b)'s corruption is detected by verifying the xor checksum of the hash entries calculated as the entries accumulate before being added to the filter. (i.e, `XXPH3FilterBitsBuilder::MaybeVerifyHashEntriesChecksum()`)
- c) - e)'s corruption is detected by verifying the hash entries indeed exists in the constructed filter by re-querying these hash entries in the filter (i.e, `FilterBitsBuilder::MaybePostVerify()`) after computing the block checksum (except for PartitionFilter, which is done right after each `FilterBitsBuilder::Finish` for impl simplicity - see code comment for more). For this stage of detection, we assume hash entries are not corrupted after checking on b) since the time interval from b) to c) is relatively short IMO.

Option to enable this feature of detection is `BlockBasedTableOptions::detect_filter_construct_corruption` which is false by default.

**Summary:**
- Implemented new functions `XXPH3FilterBitsBuilder::MaybeVerifyHashEntriesChecksum()` and `FilterBitsBuilder::MaybePostVerify()`
- Ensured hash entries, final filter and banding and their [cache reservation ](https://github.com/facebook/rocksdb/issues/9073) are released properly despite corruption
   - See [Filter.construction.artifacts.release.point.pdf ](https://github.com/facebook/rocksdb/files/7923487/Design.Filter.construction.artifacts.release.point.pdf) for high-level design
   -  Bundled and refactored hash entries's related artifact in XXPH3FilterBitsBuilder into `HashEntriesInfo` for better control on lifetime of these artifact during `SwapEntires`, `ResetEntries`
- Ensured RocksDB block-based table builder calls `FilterBitsBuilder::MaybePostVerify()` after constructing the filter by `FilterBitsBuilder::Finish()`
- When encountering such filter construction corruption, stop writing the filter content to files and mark such a block-based table building non-ok by storing the corruption status in the builder.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9342

Test Plan:
- Added new unit test `DBFilterConstructionCorruptionTestWithParam.DetectCorruption`
- Included this new feature in `DBFilterConstructionReserveMemoryTestWithParam.ReserveMemory` as this feature heavily touch ReserveMemory's impl
   - For fallback case, I run `./filter_bench -impl=3 -detect_filter_construct_corruption=true -reserve_table_builder_memory=true -strict_capacity_limit=true  -quick -runs 10 | grep 'Build avg'` to make sure nothing break.
- Added to `filter_bench`: increased filter construction time by **30%**, mostly by `MaybePostVerify()`
   -  FastLocalBloom
       - Before change: `./filter_bench -impl=2 -quick -runs 10 | grep 'Build avg'`: **28.86643s**
       - After change:
          -  `./filter_bench -impl=2 -detect_filter_construct_corruption=false -quick -runs 10 | grep 'Build avg'` (expect a tiny increase due to MaybePostVerify is always called regardless): **27.6644s (-4% perf improvement might be due to now we don't drop bloom hash entry in `AddAllEntries` along iteration but in bulk later, same with the bypassing-MaybePostVerify case below)**
          - `./filter_bench -impl=2 -detect_filter_construct_corruption=true -quick -runs 10 | grep 'Build avg'` (expect acceptable increase): **34.41159s (+20%)**
          - `./filter_bench -impl=2 -detect_filter_construct_corruption=true -quick -runs 10 | grep 'Build avg'` (by-passing MaybePostVerify, expect minor increase): **27.13431s (-6%)**
    -  Standard128Ribbon
       - Before change: `./filter_bench -impl=3 -quick -runs 10 | grep 'Build avg'`: **122.5384s**
       - After change:
          - `./filter_bench -impl=3 -detect_filter_construct_corruption=false -quick -runs 10 | grep 'Build avg'` (expect a tiny increase due to MaybePostVerify is always called regardless - verified by removing MaybePostVerify under this case and found only +-1ns difference): **124.3588s (+2%)**
          - `./filter_bench -impl=3 -detect_filter_construct_corruption=true -quick -runs 10 | grep 'Build avg'`(expect acceptable increase): **159.4946s (+30%)**
          - `./filter_bench -impl=3 -detect_filter_construct_corruption=true -quick -runs 10 | grep 'Build avg'`(by-passing MaybePostVerify, expect minor increase) : **125.258s (+2%)**
- Added to `db_stress`: `make crash_test`, `./db_stress --detect_filter_construct_corruption=true`
- Manually smoke-tested: manually corrupted the filter construction in some db level tests with basic PUT and background flush. As expected, the error did get returned to users in subsequent PUT and Flush status.

f6d7ec1d02 Ignore total_order_seek in DB::Get (#9427)
Summary:
Apparently setting total_order_seek=true for DB::Get was
intended to allow accurate read semantics if the current prefix
extractor doesn't match what was used to generate SST files on
disk. But since prefix_extractor was made a mutable option in 5.14.0, we
have been able to detect this case and provide the correct semantics
regardless of the total_order_seek option. Since that time, the option
has only made Get() slower in a reasonably common case: prefix_extractor
unchanged and whole_key_filtering=false.

So this change primarily removes unnecessary effect of
total_order_seek on Get. Also cleans up some related comments.

Also adds a -total_order_seek option to db_bench and canonicalizes
handling of ReadOptions in db_bench so that command line options have
the expected association with library features. (There is potential
for change in regression test behavior, but the old behavior is likely
indefensible, or some other inconsistency would need to be fixed.)

TODO in follow-up work: there should be no reason for Get() to depend on
current prefix extractor at all.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9427

Test Plan:
Unit tests updated.

Performance (using db_bench update)

Create DB with `TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -benchmarks=fillrandom -num=10000000 -disable_wal=1 -write_buffer_size=10000000 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -prefix_size=12 -whole_key_filtering=0`

Test with and without `-total_order_seek` on `TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -use_existing_db -readonly -benchmarks=readrandom -num=10000000 -duration=40 -disable_wal=1 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -prefix_size=12`

Before this change, total_order_seek=false: 25188 ops/sec
Before this change, total_order_seek=true:   1222 ops/sec (~20x slower)

After this change, total_order_seek=false: 24570 ops/sec
After this change, total_order_seek=true:  25012 ops/sec (indistinguishable)

c7ce03dce1 db_stress begin tracking expected state after verification (#9470)
Summary:
Previously we enabled tracking expected state changes during
`FinishInitDb()`, as soon as the DB was opened. This meant tracing was
enabled during `VerifyDb()`. This cost extra CPU by requiring
`DBImpl::trace_mutex_` to be acquired on each read operation. It was
unnecessary since we know there are no expected state changes during the
`VerifyDb()` phase. So, this PR delays tracking expected state changes
until after the `VerifyDb()` phase has completed.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9470

Test Plan:
Measured this PR reduced `VerifyDb()` 76% (387 -> 92 seconds) with
`-disable_wal=1` (i.e., expected state tracking enabled).

8dbd0bd11f db_crashtest.py use cheaper settings (#9476)
Summary:
Despite attempts to optimize `db_stress` setup phase (i.e.,
pre-`OperateDb()`) latency in https://github.com/facebook/rocksdb/issues/9470 and https://github.com/facebook/rocksdb/issues/9475, it still always took tens
of seconds. Since we still aren't able to setup a 100M key `db_stress`
quickly, we should reduce the number of keys. This PR reduces it 4x
while increasing `value_size_mult` 4x (from its default value of 8) so
that memtables and SST files fill at a similar rate compared to before this PR.

Also disabled bzip2 compression since we'll probably never use it and
I noticed many CI runs spending majority of CPU on bzip2 decompression.

f07c56928f Set the number of threads up front in db_stress (#9466)
Summary:
With the code on main, `RunStressTest` increments the number of threads
one by one as the threads are created and started. This results in a
data race with `NonBatchedOpsStressTest::VerifyDb`, which reads this
value without synchronization, and is also not correct in the sense
that `VerifyDb` assumes that the number of threads already has its final
value set (e.g. it's checking whether the current thread is the last
one). The patch fixes this by setting the number of threads before
creating/starting any threads. This also eliminates the need for locking
the mutex during thread startup.

- Keep `soft_rate_limit`/`hard_rate_limit` in `cf_mutable_options_type_info` to prevent throwing `InvalidArgument` in `GetColumnFamilyOptionsFromMap` when reading an option file still with these options (e.g, old option file generated from RocksDB before the deprecation)
- Keep `soft_rate_limit`/`hard_rate_limit` in under `OptionsOldApiTest.GetOptionsFromMapTest` to test the case mentioned above.

dd203ed604 Disallow a combination of options (#9348)
Summary:
Disallow `immutable_db_opts.use_direct_io_for_flush_and_compaction == true` and
`mutable_db_opts.writable_file_max_buffer_size == 0`, since it causes `WritableFileWriter::Append()`
to loop forever and does not make much sense in direct IO.

This combination of options itself does not make much sense: asking RocksDB to do direct IO but not allowing
RocksDB to allocate a buffer. We should detect this false combination and warn user early, no matter whether
the application is running on a platform that supports direct IO or not. In the case of platform **not** supporting
direct IO, it's ok if the user learns about this and then finds that direct IO is not supported.

One tricky thing: the constructor of `WritableFileWriter` is being used in our unit tests, and it's impossible
to return status code from constructor. Since we do not throw, I put an assertion for now. Fortunately,
the constructor is not exposed to external applications.

ea89c77f27 Fix major bug with MultiGet, DeleteRange, and memtable Bloom (#9453)
Summary:
MemTable::MultiGet was not considering range tombstones before
querying Bloom filter. This means range tombstones would be skipped for
keys (or prefixes) with no other entries in the memtable. This could cause
old values for a key (in SST files) to still show up until the range tombstone
covering it has been flushed.

This is fixed by essentially disabling the memtable Bloom filter when there
are any range tombstones. (This could be better optimized in the future, but
good enough for now.)

Did some other cleanup/optimization in the same code to (more than) offset
the cost of checking on range tombstones in more cases. There is now
notable improvement when memtable_whole_key_filtering and prefix_extractor
are used together (unusual), and this makes MultiGet closer to the Get
implementation.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9453

Test Plan:
new unit test added. Added memtable Bloom to crash test.

Performance testing
--------------------

Build WAL-only DB (recovers to memtable):
```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -benchmarks=fillrandom -num=1000000 -write_buffer_size=250000000
```

Query test command, to maximize sensitivity to the changed code:
```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -use_existing_db -readonly -benchmarks=multireadrandom -num=10000000 -write_buffer_size=250000000 -memtable_bloom_size_ratio=0.015 -multiread_batched -batch_size=24 -threads=8 -memtable_whole_key_filtering=$MWKF -prefix_size=$PXS
```
(Note -num here is 10x larger for mostly memtable misses)

Before & after run simultaneously, average over 10 iterations per data point, ops/sec.

MWKF=0 PXS=0 (Bloom disabled)
Before: 5724844
After: 6722066

MWKF=0 PXS=7 (prefixes hardly unique; Bloom not useful)
Before: 9981319
After: 10237990

MWKF=0 PXS=8 (prefixes unique; Bloom useful)
Before:  12081715
After: 12117603

MWKF=1 PXS=0 (whole key Bloom useful)
Before: 11944354
After: 12096085

MWKF=1 PXS=7 (whole key Bloom useful in new version; prefixes not useful in old version)
Before: 9444299
After: 11826029

MWKF=1 PXS=7 (whole key Bloom useful in new version; prefixes useful in old version)
Before: 11784465
After: 11778591

Only in this last case is the 'before' *slightly* faster, perhaps because hashing prefixes is slightly faster than hashing whole keys. Otherwise, 'after' is faster.

37ec9d0c12 Improve performance of SliceTransform::AsString (#9401)
Summary:
1. Removed the options from the Capped/Fixed SliceTransforms.  Instead these classes are created with id.number.  This allows the GetID() id to be calculated and stored at class construction time.  This change puts the construction back to similar to how it was prior to the Customizable changes for SliceTransform.

2.  Improve the performance of AsString by using the ID only if there are no option properties (which is the case for all of the builtin transforms).

Ran tests of calling AsString in a loop 5M times and found approximately a 10x performance increase vs the original code.

449029f865 Remove deprecated ObjectLibrary::Register() (and Regex public API) (#9439)
Summary:
Regexes are considered potentially problematic for use in
registering RocksDB extensions, so we are removing
ObjectLibrary::Register() and the Regex public API it depended on (now
unused).

In reference to https://github.com/facebook/rocksdb/issues/9389

Why?
* The power of Regexes can make it hard to reason about which extension
will match what. (The replacement API isn't perfect, but we are at least
"holding the line" on patterns we have seen in practice.)
* It is easy to make regexes that don't quite mean what you think they
mean, such as forgetting that the `.` in `foo.bar` can match any character
or that matching is nondeterministic, as in `a🅱️42` matching `.*:[0-9]+`.
* Some regexes and implementations can have disastrously bad
performance. This might not be much practical concern for ObjectLibray
here, but we don't want to encourage potentially dangerous further use
in production code. (Testing code is fine. See TestRegex.)

11d7329503 Clarify status-handling logic in BlockBasedTableBuilder::WriteRawBlock (#9393)
Summary:
**Context:**
Inside `BlockBasedTableBuilder::WriteRawBlock`, there are multiple places that change local variables `io_s` and `s` while
depend on them. This PR attempts to clarify the relevant logics so that it's easier to read and add places of changing these local variables later (like https://github.com/facebook/rocksdb/pull/9342.) without changing the current behavior.

**Summary:**
- Shorten the lifetime of local var `io_s` and `s` as much as possible to avoid if-else branches by early return

**Test**
- Reasoned against original behavior to verify new changes do not break existing behaviors.
- Rely on CI tests since we are not changing current behavior.

Plus, rdb requires python2 which is not supported any more. No fixes or improvements will be made, even for potential

1cecd22de9 Increase wait time within EnvPosixTestWithParam.RunMany (#9413)
Summary:
We see:

[ RUN      ] ChrootEnvWithDirectIO/EnvPosixTestWithParam.RunMany/0
env/env_test.cc:464: Failure
Expected equality of these values:
  4
  cur
    Which is: 0

The suspicious is that the wait time is not long enough. Increase the wait time to 10s and allows earlier check.

Test Plan: Run the test

a750b8a3a3 Remove VS2017 from Appveyor CI (#9417)
Summary:
It appears that VS2017 is covered in CircleCI so we don't need it in Appveyor. Also, currently Appveyor has some problem with installing VS2017.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9417

Test Plan: Watch Appveyor run.
