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)
Test Plan:
make rocksdbjava
make jtest

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
Test Plan:

Summary:
Options extends now two interfaces DBOptionsInterface
and ColumnFamilyOptionsInterface. There are also further
improvements to the Options bindings:
Optimize methods were ported to Java. (OptimizeForPointLookup,
OptimizeLevelCompaction, OptimizeUniversalCompaction).
To align BuiltinComparator with every other Enum it was moved to
a separate file.
Test Plan:
make rocksdbjava
make jtest
Summary:
- BackupableDB deleteBackup method
- BackupableDB purgeOldBackups bugfix
- BackupInfos now available in Restorable-/BackupableDB
- Extended BackupableDBTest to cover more of the currently implemented functionality.
Test Plan:
make rocksdbjava
make jtest

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().
Summary:
Snapshots integration into RocksJava. Added support for the following functionalities:
- getSnapshot
- releaseSnapshot
- ReadOptions support to set a Snapshot
- ReadOptions support to retrieve Snapshot
- SnapshotTest
