ad0d70ca1e Relax asserts in arena_test
Summary:
Commit c67d206898 did not fix all test conditions
which use Arena::MemoryAllocatedBytes() (see Travis failure
https://travis-ci.org/facebook/rocksdb/jobs/79957700). The assumption of that
commit was that aligned allocations do not call Arena::AllocateNewBlock(), so
malloc_usable_block_size() would not be used for Arena::MemoryAllocatedBytes().
However, there is a code path where Arena::AllocateAligned() calls
AllocateFallback() which in turn calls Arena::AllocateNewBlock(), so
Arena::MemoryAllocatedBytes() may return a greater value than expected even for
aligned requests.

03ddce9a01 Add counters for L0 stall while L0-L1 compaction is taking place
Summary:
Although there are currently counters to keep track of the
stall caused by having too many L0 files, there is no distinction as
to whether when that stall occurs either (A) L0-L1 compaction is taking
place to try and mitigate it, or (B) no L0-L1 compaction has been scheduled
at the moment. This diff adds a counter for (A) so that the nature of L0
stalls can be better understood.

c67d206898 Fixed arena_test failure due to malloc_usable_size()
Summary:
ArenaTest.MemoryAllocatedBytes on Travis failed:
https://travis-ci.org/facebook/rocksdb/jobs/79887849 . This is probably due to
malloc_usable_size() returning a value greater than the requested size. From
the man page:

   The value returned by malloc_usable_size() may be greater than the requested
   size of the allocation because of alignment and minimum size constraints.
   Although the excess bytes can be overwritten by the application without ill
   effects, this is not good programming practice: the number of excess bytes
   in an allocation depends on the underlying implementation.

30e82d5c41 Refactor to support file_reader_writer on Windows.
Summary. A change https://reviews.facebook.net/differential/diff/224721/
  Has attempted to move common functionality out of platform dependent
  code to a new facility called file_reader_writer.
  This includes:
  - perf counters
  - Buffering
  - RateLimiting

  However, the change did not attempt to refactor Windows code.
  To mitigate, we introduce new quering interfaces such as UseOSBuffer(),
  GetRequiredBufferAlignment() and ReaderWriterForward()
  for pure forwarding where required.
  Introduce WritableFile got a new method Truncate(). This is to communicate
  to the file as to how much data it has on close.
   - When space is pre-allocated on Linux it is filled with zeros implicitly,
    no such thing exist on Windows so we must truncate file on close.
   - When operating in unbuffered mode the last page is filled with zeros but we still want to truncate.

   Previously, Close() would take care of it but now buffer management is shifted to the wrappers and the file has
   no idea about the file true size.

   This means that Close() on the wrapper level must always include
   Truncate() as well as wrapper __dtor should call Close() and
   against double Close().
   Move buffered/unbuffered write logic to the wrapper.
   Utilize Aligned buffer class.
   Adjust tests and implement Truncate() where necessary.
   Come up with reasonable defaults for new virtual interfaces.
   Forward calls for RandomAccessReadAhead class to avoid double
   buffering and locking (double locking in unbuffered mode on WIndows).

6db0a939d2 Fix DBCompactionTest failure with parallel L0-L1 compactions
Summary:
The test SuggestCompactRangeNoTwoLevel0Compactions in
DBCompactionTest fails when there are parallel L0-L1 compactions
taking place because the test makes sure that only one compaction
involving L0 takes place at any given time (since before having
parallel compactions this was impossible). I changed the test to only
run with DBOptions.max_subcompactions=1 so as to not hit this issue
which is not a correctness issue but just an inherent changing of
assumptions after introducing parallel compactions.

This failed after landing https://reviews.facebook.net/D43269#inline-321303

3c37b3cccd Determine boundaries of subcompactions
Summary:
Up to this point, the subcompactions that make up a compaction
job have been divided based on the key range of the L1 files, and each
subcompaction has handled the key range of only one file. However
DBOption.max_subcompactions allows the user to designate how many
subcompactions at most to perform. This patch updates the
CompactionJob::GetSubcompactionBoundaries() to determine these
divisions accordingly based on that option and other input/system factors.

The current approach orders the starting and/or ending keys of certain
compaction input files and then generates a histogram to approximate the
size covered by the key range between each consecutive pair of keys. Then
it groups these ranges into groups so that the sizes are approximately equal
to one another. The approach has also been adapted to work for universal
compaction as well instead of just for level-based compaction as it was before.

These subcompactions are then executed in parallel by locally spawning
threads, one for each. The results are then aggregated and the compaction
completed.

checksum passes. We do have customer issues where the record checksum passed but
the data was incomprehensible. There is no way to get out of this error case

3a0df7f161 Fixed comparison in ForwardIterator when computing hint for GetNextLevelIndex()
Summary: When computing the hint for GetNextLevelIndex(), ForwardIterator was doing a redundant comparison. This patch fixes the comparison (using https://github.com/facebook/rocksdb/blob/master/db/version_set.cc#L158 as a reference) and moves it inside an assert because we expect `level_files[f_idx]` to contain the next key after Seek(), so user_key should always be smaller than the largest key.

insert when the mutable iterator is not current. The test is also
improved and the check for deleted iterators is made more informative.
