Summary:
When an iterator reseek happens with the user specifying a new iterate_upper_bound in ReadOptions, and the new seek position is at the end of the same data block, the Seek() ends up using a stale value of data_block_within_upper_bound_ and may return incorrect results.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/5883
Test Plan: Added a new test case DBIteratorTest.IterReseekNewUpperBound. Verified that it failed due to the assertion failure without the fix, and passes with the fix.

Summary:
When multiple operations are performed in a db_stress thread in one loop
iteration, the reopen voting logic needs to take that into account. It
was doing that for MultiGet, but a new option was introduced recently to
do multiple iterator seeks per iteration, which broke it again. Fix the
logic to be more robust and agnostic of the type of operation performed.

the handling of serialized Bloom filter bits that cannot be generated by
FullFilterBitsBuilder in the current compilation. These now test many of

Iterator verification in stress tests sometimes fail for assertion
table/block_based/block_based_table_reader.cc:2973: void rocksdb::BlockBasedTableIterator<TBlockIter, TValue>::FindBlockForward() [with TBlockIter = rocksdb::DataBlockIter; TValue = rocksdb::Slice]: Assertion `!next_block_is_out_of_bound || user_comparator_.Compare(*read_options_.iterate_upper_bound, index_iter_->user_key()) <= 0' failed.
It is likely to be linked to https://github.com/facebook/rocksdb/pull/5286 together with https://github.com/facebook/rocksdb/pull/5468 as the former PR makes some child iterator's seek being avoided, so that upper bound condition fails to be updated there.

Summary:
Two more bug fixes in db_stress:
1. this is to complete the fix of the regression bug causing overflowing when supporting FLAGS_prefix_size = -1.
2. Fix regression bug in compare iterator itself:
(1) when creating control iterator, which used the same read option as the normal iterator by mistake; (2) the logic of comparing has some problems. Fix them.
(3) disable validation for lower bound now, which generated some wildly different results. Disabling it to make normal tests pass while investigating it.
3. Cleaning up snapshots in verification failure cases. Memory is leaked otherwise.

Summary:
Atomic flush is incompatible with pipelined write. At least now.
If pipelined write is enabled, a thread performing write can exit the write
thread and start inserting into memtables. Consequently a thread performing
flush will enter write thread and race with memtable insertion by the former.
This will cause undefined result in terms of data persistence.

Summary:
For now, crash_test is not able to report any failure for the logic related to iterator upper, lower bounds or iterators, or reseek. These are features prone to errors. Improve db_stress in several ways:
(1) For each iterator run, reseek up to 3 times.
(2) For every iterator, create control iterator with upper or lower bound, with total order seek. Compare the results with the iterator.
(3) Make simple crash test to avoid prefix size to have more coverage.
(4) make prefix_size = 0 a valid size and -1 to indicate disabling prefix extractor.

Summary:
Partitioned filters make use of a top-level index to find the partition in which the filter resides. The top-level index has a key per partition. The key is guaranteed to be larger or equal than any key in that partition. When used with format_version 3, which excludes the sequence number form index keys, the separator key in the index could be equal to the prefix of the keys in the next partition. In this way, when searching for the key, the top-level index will lead us to the previous partition, which has no key with that prefix. The prefix bloom test thus returns false, although the prefix exists in the bloom of the next partition.
The patch fixes that by a hack: It always adds the prefix of the first key of the next partition to the bloom of the current partition. In this way, in the corner cases that the index will lead us to the previous partition, we still can find the bloom filter there.

Summary:
format-diff.sh, a.k.a. 'make format', would use 'master'
to decide which commits are probably unpublished. Much better to use
facebook remote master since local master may not be caught up and may
have its own unpublished commits. Script now tries to compare against
facebook remote master branch (branch pointer is updated with any fetch
or pull), because those differences are what would be considered the
differences for a pull request.
Also, script would compare against *parent* of merge-base with that
reference point, which is just wrong since that includes the last
published commit.
In case of problems, you can now customize the reference point, by
setting the FORMAT_UPSTREAM variable.

Summary:
For our default block cache, each additional entry has extra memory overhead. It include LRUHandle (72 bytes currently) and the cache key (two varint64, file id and offset). The usage is not negligible. For example for block_size=4k, the overhead accounts for an extra 2% memory usage for the cache. The patch charging the cache for the extra usage, reducing untracked memory usage outside block cache. The feature is enabled by default and can be disabled by passing kDontChargeCacheMetadata to the cache constructor.
This PR builds up on https://github.com/facebook/rocksdb/issues/4258
Pull Request resolved: https://github.com/facebook/rocksdb/pull/5797
Test Plan:
- Existing tests are updated to either disable the feature when the test has too much dependency on the old way of accounting the usage or increasing the cache capacity to account for the additional charge of metadata.
- The Usage tests in cache_test.cc are augmented to test the cache usage under kFullChargeCacheMetadata.
