Summary:
Within this commit a new AbstractLogger was introduced
which allows to handle log messages at an application level.
Log messages are passed up to Java using a JNI callback.
This allows a Java-Developer to use common Java APIs for log
messages e.g. SLF4J, LOG4J, etc. Within this commit no new
dependencies were introduced, which keeps the RocksDB API clean
and doesn`t force a developer to use a predefined high-level Java API.
Another feature is to dynamically set a custom loggers verbosity at
runtime using its public method `setInfoLogLevel` and to retrieve
the currently active level using the `infoLogLevel` method.
Test Plan:
make clean jclean rocksdbjava jtest
mvn -f rocksjni.pom package

Summary:
Cleaned up some tests regarding disposal order and tests
which were failing when C++ assertions were enabled.
Test Plan:
- Enable C++ Assertions (remove e.g. -DNDebug in rocksdbjava target)
- make rocksdbjava jtest

In the current implementation DefaultColumnFamily will not disown
the native handle. As the database handles the lease on the native
handle this should be the case.
Summary:
Introduced final keyword to parameters with immutable values and classes
which should not be derived.
Test Plan:
make rocksdbjava
make jtest

Summary:
Bytes are currently misinterpreted by the Java if the
byte array contains zero bytes within its content. For Strings
thats usually not useful. As the Java API allows every kind
of byte array values it might be the case that zero padding might
happen.

from either java.library.path or from extracting from the Jar. Means
that the test in the build do not need to rely on the Jar, useful when
creating similar builds (and executing tests) from Maven
Summary:
As the C++ part exposes now SequenceNumber retrieval
for Snapshots we want this obviously also in the Java API.
Test Plan:
make rocksdbjava
make jtest
mvn -f rocksjni.pom test

Summary:
Simple Java Native Objects usually are represented using
the same functionality but within different classes.
With this commit a template class was introduced to remove
the redundant impelementation to a certain extent.
[RocksJava] Removed todo comment in portal.h
As jclass instances shall not be cached, both
todos are obsolete and can be removed.
[RocksJava] Add missing test to Makefile
[RocksJava] Added tests for uncovered methods
Test Plan:
make rocksdbjava
make jtest
mvn -f rocksjni.pom package

Simple Java Native Objects usually are represented using

With this commit a template class was introduced to remove
the redundant impelementation to a certain extent.
Summary:
Prior to this the native library loader instance didn`t
care about a state. So if library loading was called multiple
times, multiple copies of the shared object were put into
the tmp folder and loaded into the JVM.
This changed within this commit to the following behavior:
- library loading is now synchronized
- library is loaded within the first call
- if loading was successful the library loaded sets a flag
- every subsequent call checks for a boolean flag indicating if there was
already a successful attempt
Test Plan:
- Execute example and watch tmp folder while the example is running
- After this patch only one shared object will be in the tmp folder
Usual tests:
- make rocksdbjava jtest
- mvn -f rocksjni.pom package

The methods:
- newIterator
- iterators
support now also ReadOptions. That allows a user of the Java API
to retrieve RocksIterator instances on a snapshot.
Summary:
Previous to this commit there was a problem with unterminated
String usage as jByteArrays are not zero terminated.
Test Plan:
make rocksdbjava
make jtest
mvn -f rocksjni.pom package
