RocksDB introduced in 3.7.0 convenience methods
for getting ColumnFamilyOptions and DBOptions
instances from predefined configuration structures.
There is now also a method in RocksJava to load DBOptions
as well as ColumnFamilyOptions from a predefined Properties
based configuration.
Summary:
The very last reference happens in DBImpl::GetOptions()
I built with both DBImpl::GetOptions() and ColumnFamilyData::options() commented out
Test Plan: make all check

Expose GetIntProperty methods to RocksJava. As the integer(64-Bit)
value is no integer in Java the method is aligned with the return
type which is long.
Summary:
As we had the discussion some weeks ago. Java needs a test framework and should support code coverage analysis. This pull request includes:
Move Tests from main method functionality to Junit4
Move WriteBatchTest to test package
Adjust the Makefile to run Junit4
Download dependencies from Make (once if not-present)
Adjustment of the rocksjni.pom to run coverage analysis using jacoco
Javadoc excludes now tests
Two bugfixes regarding GC cleanup which came up within the test runs
Make can be used as beforehand to build and run RocksJava. make test runs tests using the command-line version of Junit4.
Maven can be used to retrieve code coverage reports using mvn -f rocksjni.pom package. Code coverage reports can then be found as usual in the site folder.
Testing libraries available within Java
Junit4 (incl. hamcrest-core dependency)
AssertJ (providing fluent syntax for assertions, cglib dependency)
Mockito to provide mocktests
Libraries as said before are not statically within this commit or filesystem instead they are downloaded using curl. Make checks if files are present, if so it will perform tests without downloading the libraries again.
Note: Libraries are only necessary to compile & run tests.
Next steps after merge:
Get the maven build into travis-ci and coveralls.io
Filling up the missing test spots (based on coverage data)

We need to turn on -Wshorten-64-to-32 for mobile. See D1671432 (internal phabricator) for details.
This diff turns on the warning flag and fixes all the errors. There were also some interesting errors that I might call bugs, especially in plain table. Going forward, I think it makes sense to have this flag turned on and be very very careful when converting 64-bit to 32-bit variables.

Summary:
ColumnFamilyHandles face the same problem as RocksIterator previously
so used methods were also applied for ColumnFamilyHandles.
Another problem with CF was that Options passed to CFs were
always filled with default values. To enable Merge, all parts
of the database must share the same merge functionality which
is not possible using default values. So from now on every
CF will inherit from db options.
Changes to RocksDB:
- merge can now take also a cfhandle
Changes to MergeTest:
- Corrected formatting
- Included also GC tests
- Extended tests to cover CF related parts
- Corrected paths to cleanup properly within the test process
- Reduced verbosity of the test

and ColumnFamilyOptionsInterface. There are also further
improvements to the Options bindings:
Optimize methods were ported to Java. (OptimizeForPointLookup,

RocksIterator will sometimes Sigsegv on dispose. Mainly thats related
to dispose order. If the related RocksDB instance is freed beforehand
RocksIterator.dispose() will fail.
Within this commit there is a major change to RocksIterator. RocksIterator
will hold a private reference to the RocksDB instance which created the
RocksIterator. So even if RocksDB is freed in the same GC cycle the
RocksIterator instances will be freed prior to related RocksDB instances.
Another aspect targets the dispose logic if the RocksDB is freed previously
and already gc`ed. On dispose of a RocksIterator the dispose logic will check
if the RocksDB instance points to an initialized DB. If not the dispose logic
will not perform any further action.
The crash can be reproduced by using the related test provided within this
commit.
Related information: This relates to @adamretter`s facebook rocksdb-dev group
post about SigSegv on RocksIterator.dispose().

Previous to this commit Filters passed as parameters to the
BlockTableConfig are disposed before they should be disposed.
Further Smart pointer usage was corrected.
Java holds now the smart pointer to the FilterPolicy correctly
and cares about freeing underlying c++ structures.
Summary:
Added support for the merge operation to RocksJava.
You can specify a merge function to be used on the current database.
The merge function can either be one of the functions defined in
utilities/merge_operators.h, which can be specified through its
corresponding name, or a user-created function that needs to be
encapsulated in a JNI object in order to be used. Examples are
provided for both use cases.
Test Plan: There are unit test in MergeTest.java

Summary:
This pull request solves the jlong overflow problem on 32-Bit machines as described in https://github.com/facebook/rocksdb/issues/278:
1. There is a new org.rocksdb.test.PlatformRandomHelper to assist in getting random values. For 32 Bit the getLong method is overriden by xpromaches code above. For 64 Bit it behaves as is.
2. The detection should be cross-platform (Windows is supported though it is not ported completely yet).
3. Every JNI method which sets jlong values must check if the value fits into size_t. If it overflows size_t a InvalidArgument Status object will be returned. If its ok a OK Status will be returned.
4. Setters which have this check will throw a RocksDBException if its no OK Status.
Additionally some other parts of code were corrected using the wrong type casts.

Extended Built-in comparators with ReverseBytewiseComparator.
Reverse key handling is under certain conditions essential. E.g. while
using timestamp versioned data.
As native-comparators were not available using JAVA-API. Both built-in comparators

[Java] Optimize statistics collector
* Optimize statistics collector by collecting statistics of multiple DBs in a single thread rather than starting up a new thread for each DB.
* Also, fix packaging of jnilib file on OS_X platform.
* Diff review: https://reviews.facebook.net/D20265
[Java] Add documentation on interdependency of dispose call of RocksObjects
* Remove transferCppRawPointersOwnershipFrom function.
- This function was setting opt.filter_ and thus filter_ to be null. This way there is no
one holding reference for filter object and can thus be GC'd which is not the intention.
Replaced it with storeOptionsInstace which stores options instance. Options class
internally holds Filter instance. Thus when Options is GC'd, filter reference
will be GC'd automatically.
* Added documentation explaining interdependency of Filter, Options and DB.
