fce6c892ab Advance max evicted seq in coarser granularity
Summary:
This patch advances the max_evicted_seq_ is larger granularities to reduce the overhead of updating the relevant data structures.

It also refactor the related code and adds testing to that. As part of this patch some of the TODOs for removing usage of non-static const members are also addressed.

ba3c58cab6 specify SSE42 'target' attribute for Fast_CRC32()
Summary:
if we enable SSE42 globally when compiling the tree for preparing a
portable binary, which could be running on CPU w/o SSE42 instructions
even the GCC on the building host is able to emit SSE42 code, this leads
to illegal instruction errors on machines not supporting SSE42. to solve
this problem, crc32 detects the supported instruction at runtime, and
selects the supported CRC32 implementation according to the result of
`cpuid`. but intrinics like "_mm_crc32_u64()" will not be available
unless the "target" machine is appropriately specified in the command
line, like "-msse42", or using the "target" attribute.

we could pass "-msse42" only when compiling crc32c.cc, and allow the
compiler to generate the SSE42 instructions, but we are still at the
risk of executing illegal instructions on machines does not support
SSE42 if the compiler emits code that is not guarded by our runtime
detection. and we need to do the change in both Makefile and CMakefile.

or, we can use GCC's "target" attribute to enable the machine specific
instructions on certain function. in this way, we have finer grained
control of the used "target". and no need to change the makefiles. so
we don't need to duplicate the changes on both makefile and cmake as
the previous approach.

this problem surfaces when preparing a package for GNU/Linux distribution,
and we only applies to optimization for SSE42, so using a feature
only available on GCC/Clang is not that formidable.

b97685aef6 fix backup engine when latest backup corrupt
Summary:
Backup engine is intentionally openable even when some backups are corrupt. Previously the engine could write new backups as long as the most recent backup wasn't corrupt. This PR makes the backup engine able to create new backups even when the most recent one is corrupt.

We now maintain two ID instance variables:

- `latest_backup_id_` is used when creating backup to choose the new ID
- `latest_valid_backup_id_` is used when restoring latest backup since we want most recent valid one

06b37eef7b Set defaults for high-pri and low-pri thread pools in regression test script
Summary:
**Summary**:
Set defaults for high-pri and low-pri thread pools in regression test script.

**Reason for this change**:
With #2680 , high-pri and low-pri thread pools get different numbers than before if  `num_high_pri_threads` and `num_low_pri_threads` options are not explicitly passed to db_bench in regression test script ... leading to a false-positive regression.

**Test Plan**:
REMOTE_HOST=udb1671.prn3 TEST_MODE=1 FBSOURCE=~/fbsource ~/fbsource/fbcode/rocks/tools/debug_regression_test.sh viewstate  (with very minor changes to the internals).

Observe P50 and P99 which showed up as regressions in our graphs.

Summary:
Allow user to reduce number of levels in LSM by issue a full CompactRange() and put the result in a lower level, and then reopen DB with reduced options.num_levels. Previous this will fail on reopen on when recovery replaying the previous MANIFEST and found a historical file was on a higher level than the new options.num_levels. The workaround was after CompactRange(), reopen the DB with old num_levels, which will create a new MANIFEST, and then reopen the DB again with new num_levels.

This patch relax the check of levels during recovery. It allows DB to open if there was a historical file on level > options.num_levels, but was also deleted.

store a zero as the checksum when disabled since it's easier to keep block trailer a fixed length.

19cc66dc4f fix clang bug in block-based table reader
Summary:
This is the warning that clang considers a bug and has been causing it to fail:

```
table/block_based_table_reader.cc:240:27: warning: Potential leak of memory pointed to by 'block.value'
    for (; biter.Valid(); biter.Next()) {
                          ^~~~~
```

Actually clang just doesn't have enough knowledge to statically determine it's safe. We can teach it using an assert.

7eba54eb9b test compaction input-level split range tombstone assumption
Summary:
One of the core assumptions of DeleteRange is that files containing portions of the same range tombstone are treated as a single unit from the perspective of compaction picker. Need better tests for this. This PR adds the tests for manual compaction.

234f33a3f9 allow nullptr Slice only as sentinel
Summary:
Allow `Slice` holding nullptr as a sentinel value but not in comparisons. This new restriction eliminates the need for the manual checks in 39ef900551, while still conforming to glibc's `memcmp` API. Thanks siying for the idea. Users may need to migrate, so mentioned it in HISTORY.md.

ccf7f833e3 Use PinnableSlice in Transactions
Summary:
The ::Get from DB is not augmented with an overload method that takes a PinnableSlice instead of a string. Transactions however are not yet upgraded to use the new API. As a result, transaction users such as MyRocks cannot benefit from it. This patch updates the transactional API with a PinnableSlice overload.

Summary:
This is the continuation of https://github.com/facebook/rocksdb/pull/2661 for filter partitions. When pin_l0 is set (along with cache_xxx), then open table open the filter partitions are loaded into the cache and pinned there.

39ef900551 stop calling memcmp with nullptrs
Summary:
it doesn't take nullptr according to its declaration in glibc, and calling it in this way causes our sanitizers (ubsan, clang analyze) to fail.
