      fix deletion dropping in intra-L0 · acf935e4
      由 Andrew Kryczka 提交于 
      Summary:
`KeyNotExistsBeyondOutputLevel` didn't consider L0 files' key-ranges. So if a key only was covered by older L0 files' key-ranges, we would incorrectly drop deletions of that key. This PR just skips the deletion-dropping optimization when output level is L0.
Closes https://github.com/facebook/rocksdb/pull/2726

      make sst_dump compression size command consistent · 8254e9b5
      由 Andrew Kryczka 提交于 
      Summary:
- like other subcommands, reporting compression sizes should be specified with the `--command` CLI arg.
- also added `--compression_types` arg as it's useful to restrict the types of compression used, at least in my dictionary compression experiments.

      db_bench support for non-uniform column family ops · 74f18c13
      由 Andrew Kryczka 提交于 
      Summary:
Previously we could only select the CF on which to operate uniformly at random. This is a limitation, e.g., when testing universal compaction as all CFs would need to run full compaction at roughly the same time, which isn't realistic.

This PR allows the user to specify the probability distribution for selecting CFs via the `--column_family_distribution` argument.

      approximate histogram stats to save cpu · 5de98f2d
      由 Andrew Kryczka 提交于 
      Summary:
sounds like we're willing to tradeoff minor inaccuracy in stats for speed. start with histogram stats. ticker stats will be harder (and, IMO, we shouldn't change them in this manner) as many test cases rely on them being exactly correct.

      Fix blob DB transaction usage while GC · e5a1b727
      由 yiwu-arbug 提交于 
      Summary:
While GC, blob DB use optimistic transaction to delete or replace the index entry in LSM, to guarantee correctness if there's a normal write writing to the same key. However, the previous implementation doesn't call SetSnapshot() nor use GetForUpdate() of transaction API, instead it do its own sequence number checking before beginning the transaction. A normal write can sneak in after the sequence number check and overwrite the key, and the GC will delete or relocate the old version of the key by mistake. Update the code to property use GetForUpdate() to check the existing index entry.

After the patch the sequence number store with each blob record is useless, So I'm considering remove the sequence number from blob record, in another patch.

      Support prefetch last 512KB with direct I/O in block based file reader · 666a005f
      由 Siying Dong 提交于 
      Summary:
Right now, if direct I/O is enabled, prefetching the last 512KB cannot be applied, except compaction inputs or readahead is enabled for iterators. This can create a lot of I/O for HDD cases. To solve the problem, the 512KB is prefetched in block based table if direct I/O is enabled. The prefetched buffer is passed in totegher with random access file reader, so that we try to read from the buffer before reading from the file. This can be extended in the future to support flexible user iterator readahead too.

      Makefile: correct faligned-new test · 1fbad84b
      由 Daniel Black 提交于 
      Summary:
Commit 4f81ab38 has the test wrong.

clang doesn't support a -dumpversion option. By lucky coincidence
clang/gcc --version both place a version number at the same output location
when --verison is passed.

Example output (1st line only).

    $ clang --version
    clang version 3.9.1 (tags/RELEASE_391/final)

    $ gcc --version
    gcc (GCC) 6.4.1 20170727 (Red Hat 6.4.1-1)

During the test of the compiler we ensure that a minimum version is met
as Makefile doesn't support patterns.

Also xcode9 doesn't seem affected by https://github.com/facebook/rocksdb/issues/2672
and also doesn't have "clang" as the first part of its output so the
fix implemented here also is Apple clang friendly.

    $ clang --version
    Apple LLVM version 9.0.0 (clang-900.0.31)
