b8d23cdcb8 Revert chrono use
Summary:
For some reason, libstdc++ implements steady_clock::now() using syscall instead of VDSO optimized clock_gettime() when using glibc 2.16 and earlier. This leads to significant performance degradation for users with older glibcs. See bug reported here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59177

We observed this behavior when testing mongo on AWS hosts. Facebook hosts are unaffected since we use glibc2.17 and 2.20.

db03739340 options.level_compaction_dynamic_level_bytes to allow RocksDB to pick size bases of levels dynamically.
Summary:
When having fixed max_bytes_for_level_base, the ratio of size of largest level and the second one can range from 0 to the multiplier. This makes LSM tree frequently irregular and unpredictable. It can also cause poor space amplification in some cases.

In this improvement (proposed by Igor Kabiljo), we introduce a parameter option.level_compaction_use_dynamic_max_bytes. When turning it on, RocksDB is free to pick a level base in the range of (options.max_bytes_for_level_base/options.max_bytes_for_level_multiplier, options.max_bytes_for_level_base] so that real level ratios are close to options.max_bytes_for_level_multiplier.

Test Plan: New unit tests and pass tests suites including valgrind.

e7c434c364 Add columnfamily option optimize_filters_for_hits to optimize for key hits only
Summary:
    Summary:
    Added a new option to ColumnFamllyOptions  - optimize_filters_for_hits. This option can be used in the case where most
    accesses to the store are key hits and we dont need to optimize performance for key misses.
    This is useful when you have a very large database and most of your lookups succeed.  The option allows the store to
     not store and use filters in the last level (the largest level which contains data). These filters can take a large amount of
     space for large databases (in memory and on-disk). For the last level, these filters are only useful for key misses and not
     for key hits. If we are not optimizing for key misses, we can choose to not store these filters for that level.

    This option is only provided for BlockBasedTable. We skip the filters when we are compacting

Test Plan:
1. Modified db_test toalso run tests with an additonal option (skip_filters_on_last_level)
 2. Added another unit test to db_test which specifically tests that filters are being skipped

ba9d1737a8 RocksDB on FreeBSD support
Summary:
This patch will update the Makefile and source code so that we can build RocksDB successfully on FreeBSD 10 and 11 (64-bit and 32-bit)
I have also encountered some problems when running tests on FreeBSD, I will try to fix them individually in different diffs

Notes:

  - FreeBSD uses clang as it's default compiler (http://lists.freebsd.org/pipermail/freebsd-current/2012-September/036480.html)
  - GNU C++ compiler have C++ 11 problems on FreeBSD (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193528)
  - make is not gmake on FreeBSD (http://www.khmere.com/freebsd_book/html/ch01.html)

Test Plan:
Using VMWare Fusion Create 4 VM machines (FreeBSD 11 64-bit, FreeBSD 11 32-bit, FreeBSD 10 64-bit, FreeBSD 10 32-bit)

  - pkg install git gmake gflags archivers/snappy
  - git clone https://github.com/facebook/rocksdb.git
  - apply this patch
  - setenv CXX c++
  - setenv CPATH /usr/local/include/
  - setenv LIBRARY_PATH  /usr/local/lib/
  - gmake db_bench
  - make sure compilation is successful and db_bench is running
  - gmake all
  - make sure compilation is successful

03b432d4b8 rocksdb: Fix uninitialized use error
Summary:
When using latest clang (3.6 or 3.7/trunck) rocksdb is failing with many errors. Some errors are uninitialized use errors.

```
...
  CC       db/log_test.o
util/ldb_cmd.cc:394:16: error: base class 'rocksdb::LDBCommand' is uninitialized when used here to access 'rocksdb::LDBCommand::BuildCmdLineOptions' [-Werror,-Wuninitialized]
               BuildCmdLineOptions({ARG_FROM, ARG_TO, ARG_HEX, ARG_KEY_HEX,
               ^
...
```

```lang=c++
CompactorCommand::CompactorCommand(const vector<string>& params,
      const map<string, string>& options, const vector<string>& flags) :
    LDBCommand(options, flags, false,
               BuildCmdLineOptions({ARG_FROM, ARG_TO, ARG_HEX, ARG_KEY_HEX,
                                    ARG_VALUE_HEX, ARG_TTL})),
    null_from_(true), null_to_(true) {
. . .
}
```
For the fourth parameter of the base constructor (`LDBCommand`) we call `BuildCmdLineOptions`, which is a private non-static method of `LDBCommand` base class.

This diff adds missing `static` keyword for `LDBCommand::BuildCmdLineOptions` method.

Test Plan:
Build with trunk clang and make sure all tests are passing.
```lang=bash
% # Have trunk clang present in path.
% ROCKSDB_NO_FBCODE=1 CC=clang CXX=clang++ make check

6fdda8ac4d rocksdb: changes to support 'make analyze' in Jenkins
Summary:
* Updated Makefile to exit `make analyze` with status 1 if scan-build detected any bugs.
* scan-build automatically detects which c++ compiler to use, and some times is uses wrong ones (from $CPP). Added implicit parameters to use $CC and $CXX.
* Added `scan_build_report` directory to .gitignore file.
* Added `scan_build_report` directory to clean target.

Test Plan:
Run `make analyze` and verify that exit status is 1, if there are scan-build bugs detected.
Run `make clean` and verify that files in `scan_build_report` directory are deleted.
After running `make analyze; git status` and verify that no untracked files in `scan_build_report` directory.

**db/log_reader.cc**
In `bool Reader::SkipToInitialBlock()` `offset_in_block` local variable is assigned to 0 `if (offset_in_block > kBlockSize - 6)` and then never used. Removed the assignment and renamed it to `initial_offset_in_block` to avoid confusion.

In `bool Reader::ReadRecord(Slice* record, std::string* scratch)` local variable `in_fragmented_record` in switch case `kFullType` block is assigned to false and then does `return` without use. In the other switch case `kFirstType` block the same `in_fragmented_record` is assigned to false, but later assigned to true without prior use. Removed assignment for both cases.

**table/plain_table_key_coding.cc**
Local variable `user_key_size` is assigned when declared. But then in both places where it is used assigned to `static_cast<uint32_t>(key.size() - 8)`. Changed to initialize the variable to the proper value in declaration.

**tools/db_stress.cc**
Missing `break` in switch case block. This seems to be a bug. Added missing `break`.

Test Plan:
Make sure all tests are passing and scan-build does not report 'Dead assignment' and 'Dead initialization' bugs.
```lang=bash
% make check
% make analyze

4f514a53d6 build: enable more compiler warnings
Summary:
* Makefile (WARNING_FLAGS): Add -W and -Wextra, and at least for now,
-Wno-unused-parameter.  Without that latter one, there would be
many errors/warnings about unused parameters.

Test Plan:
run these and ensure there is no warning:
  make clean && make
  make clean && USE_CLANG=1 make

a2b911b63f inputs: restore "const" attribute removed by D33759
Summary:
The "const" attribute applies to the type, and placing it
before that return type retains the desired semantics,
yet avoids the compiler error/warning.

Test Plan: Run make

c6d54b5037 fix erroneous assert: cast kBlockSize (of type unsigned int) to "int"
Summary:
Otherwise, we would assert that an unsigned expression is always >= 0.
The intent was to form a possibly negative number, and to assert that
that value is always >= 0, but since one variable in the computation
was unsigned, the result was guaranteed to be unsigned, too, rendering
the assertion useless.

Cast that unsigned variable to "int", so that all operands
are signed, and thus so that the result can be negative.

Test Plan:
  Run "make EXTRA_CXXFLAGS='-W -Wextra'" and see fewer errors.
