Venkatesh Radhakrishnan d2346c2cf0 Fix hang with large write batches and column families.
Summary:
This diff fixes a hang reported by a Github user.
https://www.facebook.com/l.php?u=https%3A%2F%2Fgithub.com%2Ffacebook%2Frocksdb%2Fissues%2F595%23issuecomment-96983273&h=9AQFYOWlo
Multiple large write batches with column families cause a hang.
The issue was caused by not doing flushes/compaction when the
write controller was stopped.

Test Plan: Create a DBTest from the user's test case

Mark Callaghan b6b100fe04 Remove iter_refresh_interval_us
Summary:
The default, use one iter for the whole test, isn't good. This cost me
a few hours of debugging and a few days of tessting. For readonly
that isn't realistic and for read-write that keeps a lot of old sst files around.
I remove the option because nothing uses it and not calling gettimeofday per
loop iteration adds about 3% to QPS at 20 threads.

krad d4540654e9 Optimize GetApproximateSizes() to use lesser CPU cycles.
Summary:
CPU profiling reveals GetApproximateSizes as a bottleneck for performance. The current implementation is sub-optimal, it scans every file in every level to compute the result.

We can take advantage of the fact that all levels above 0 are sorted in the increasing order of key ranges and use binary search to locate the starting index. This can reduce the number of comparisons required to compute the result.

Test Plan: We have good test coverage. Run the tests.

sdong d01bbb53ae Fix CompactRange for universal compaction with num_levels > 1
Summary:
CompactRange for universal compaction with num_levels > 1 seems to have a bug. The unit test also has a bug so it doesn't capture the problem.
Fix it. Revert the compact range to the logic equivalent to num_levels=1. Always compact all files together.

It should also fix DBTest.IncreaseUniversalCompactionNumLevels. The issue was that options.write_buffer_size = 100 << 10 and options.write_buffer_size = 100 << 10 are not used in later test scenarios. So write_buffer_size of 4MB was used. The compaction trigger condition is not anymore obvious as expected.

Giuseppe Ottaviano 2dc421df48 Implement DB::PromoteL0 method
Summary:
This diff implements a new `DB` method `PromoteL0` which moves all files in L0
to a given level skipping compaction, provided that the files have disjoint
ranges and all levels up to the target level are empty.

This method provides finer-grain control for trivial compactions, and it is
useful for bulk-loading pre-sorted keys. Compared to D34797, it does not change
the semantics of an existing operation, which can impact existing code.

PromoteL0 is designed to work well in combination with the proposed
`GetSstFileWriter`/`AddFile` interface, enabling to "design" the level structure
by populating one level at a time. Such fine-grained control can be very useful
for static or mostly-static databases.

Jim Meyering 0a91bca5db test: avoid vuln-inducing use of temporary directory
Summary:
Without this change, someone on the machine on which
I run "make check" could cause me to overwrite arbitrary
files owned by me, via a symlink attack.

Instead of using a predictable temporary directory and
accepting to use a preexisting one, always create a new
one using mkdtemp.  If $TEST_IOCTL_FRIENDLY_TMPDIR is
set and usable, attempt first to find a usable
temporary directory therein.  If not, or if unusable,
then try /var/tmp and /tmp.  If none of those is usable
abort with a diagnostic.

To do that, I added a new class.
Its constructor finds a suitable directory or aborts,
the sole member prints that directory's name, and the
destructor unlinks what should be an empty directory.

Note that while the code before this did not remove
its temporary directory, there was only one per $UID.
Now, there would be at least one per run or one per
test, depending on implementation, so it is important
to remove them.

Test Plan:
  Run this on a fedora rawhide system, where /tmp
  is a tmpfs file system, and /var/tmp is ext4.

  # This gives a diagnostic that /dev/shm is not suitable
  # and ends up using /var/tmp.
  TEST_IOCTL_FRIENDLY_TMPDIR=/dev/shm ./env_test

  # Uses /var/tmp; same as when envvar not set.
  TEST_IOCTL_FRIENDLY_TMPDIR=/var/tmp ./env_test

  # Uses /tmp unless it's tmpfs, in which case it gives
  # a diagnostic and uses /var/tmp.
  TEST_IOCTL_FRIENDLY_TMPDIR=/tmp ./env_test

Jim Meyering 79c21ec0c4 skip ioctl-using tests when not supported
Summary:
[NB: this is a prerequisite for the /tmp-abuse-fixing patch]
This avoids spurious test failure on Linux systems
like Fedora for which /tmp is a tmpfs file system.

On a devtmpfs file
system, ioctl(fd, FS_IOC_GETVERSION, &version) returns -1 with
errno == ENOTTTY, indicating that that ioctl is not supported
on such a file system.  Do not let this cause test failures, e.g.,
where env_test would assert that file->GetUniqueId(...) > 0.

Before this change, ./env_test would fail these three tests
on a fedora rawhide system:

  [  FAILED  ] 3 tests, listed below:
  [  FAILED  ] EnvPosixTest.RandomAccessUniqueID
  [  FAILED  ] EnvPosixTest.RandomAccessUniqueIDConcurrent
  [  FAILED  ] EnvPosixTest.RandomAccessUniqueIDDeletes
   3 FAILED TESTS

The fix:
  When support for that ioctl is lacking, skip each affected test.
  Could be improved by noting which sub-tests are being skipped.

Test Plan:
run these on F21 and note that they now pass.

Igor Canadi 6059bdf86a Add experimental API MarkForCompaction()
Summary:
Some Mongo+Rocks datasets in Parse's environment are not doing compactions very frequently. During the quiet period (with no IO), we'd like to schedule compactions so that our reads become faster. Also, aggressively compacting during quiet periods helps when write bursts happen. In addition, we also want to compact files that are containing deleted key ranges (like old oplog keys).

All of this is currently not possible with CompactRange() because it's single-threaded and blocks all other compactions from happening. Running CompactRange() risks an issue of blocking writes because we generate too much Level 0 files before the compaction is over. Stopping writes is very dangerous because they hold transaction locks. We tried running manual compaction once on Mongo+Rocks and everything fell apart.

MarkForCompaction() solves all of those problems. This is very light-weight manual compaction. It is lower priority than automatic compactions, which means it shouldn't interfere with background process keeping the LSM tree clean. However, if no automatic compactions need to be run (or we have extra background threads available), we will start compacting files that are marked for compaction.

Test Plan: added a new unit test

     ASSERT_EQ(false, controller.IsStopped());
                                                                                                                                                                          ^

This change was induced mechanically via:

  git grep -l -E 'ASSERT_EQ\(false'|xargs perl -pi -e 's/ASSERT_EQ\(false, /ASSERT_FALSE(/'
  git grep -l -E 'ASSERT_EQ\(true'|xargs perl -pi -e 's/ASSERT_EQ\(true, /ASSERT_TRUE(/'

Except for the three in utilities/backupable/backupable_db_test.cc for which
I ended up reformatting (joining lines) in the result.

As for why this problem is exhibited with that version of gcc, and none
of the others I've used (from 4.8.1 through gcc-5.0.0 and newer), I suspect
it's a bug in F21's gcc that has been fixed in gcc-5.0.0.

Test Plan:
  "make" now succeed on Fedora 21

Igor Canadi 48b0a045da Speed up reduce_levels_test
Summary: For some reason reduce_levels is opening the databse with 65.000 levels. This makes ComputeCompactionScore() function terribly slow and the tests is also very slow (20seconds).

Test Plan: mr reduce_levels_test now takes 20ms
