Summary:
This request is adding support for using DirectSlice in ReadOptions lower/upper bounds.
To be more efficient I have added setLength to DirectSlice so I can just update the length to be used by slice from direct buffer. It is also needed, because when one creates iterator it keep pointer to original slice so setting new slice in options does not help (it needs to reuse existing one). Using this approach one can modify the slice any time during operations with iterator.

Summary:
Classes ColumnFamilyHandle and CapturingWriteBatchHandler.Event have
byte array fields as part of their identity, but they do not use the
arrays' content to compute the instance's hash, and instead rely on the
arrays' identity, causing instances to have different hashcodes
although they are equal.
The PR addresses it by using the arrays' content to compute the hash,
like the equals method does.

Summary:
Consider the following sequence of events:
1. Db flushed an SST with file number N, appended to MANIFEST, and tried to sync the MANIFEST.
2. Syncing MANIFEST failed and db crashed.
3. Db tried to recover with this MANIFEST. In the meantime, no entry about the newly-flushed SST was found in the MANIFEST. Therefore, RocksDB replayed WAL and tried to flush to an SST file reusing the same file number N. This failed because file system does not support overwrite. Then Db deleted this file.
4. Db crashed again.
5. Db tried to recover. When db read the MANIFEST, there was an entry referencing N.sst. This could happen probably because the append in step 1 finally reached the MANIFEST and became visible. Since N.sst had been deleted in step 3, recovery failed.
It is possible that N.sst created in step 1 is valid. Although step 3 would still fail since the MANIFEST was not synced properly in step 1 and 2, deleting N.sst would make it impossible for the db to recover even if the remaining part of MANIFEST was appended and visible after step 5.
After this PR, in step 3, immediately after recovering from MANIFEST, a new MANIFEST is created, then we find that N.sst is not referenced in the MANIFEST, so we delete it, and we'll not reuse N as file number. Then in step 5, since the new MANIFEST does not contain N.sst, the recovery failure situation in step 5 won't happen.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/7621
Test Plan:
1. some tests are updated, because these tests assume that new MANIFEST is created after WAL recovery.
2. a new unit test is added in db_basic_test to simulate step 3.

- some of the existing tests that exercise the "internal key too small" condition are: dbformat_test, cuckoo_table_builder_test
- some of the existing tests that exercise the corrupted key path are: corruption_test, merge_helper_test, compaction_iterator_test
Example of new status returns:
- Key too small - `Corrupted Key: Internal Key too small. Size=5`
- Corrupt key with allow_data_in_errors option set to false: `Corrupted Key: '<redacted>' seq:3, type:3`
- Corrupt key with allow_data_in_errors option set to true: `Corrupted Key: '61' seq:3, type:3`

Summary:
- Takes the burden off developer to close ColumnFamilyHandle instances before closing RocksDB instance
- The change is backward-compatible
----
Previously the pattern for working with Column Families was:
```java
try (final ColumnFamilyOptions cfOpts = new ColumnFamilyOptions().optimizeUniversalStyleCompaction()) {
// list of column family descriptors, first entry must always be default column family
final List<ColumnFamilyDescriptor> cfDescriptors = Arrays.asList(
new ColumnFamilyDescriptor(RocksDB.DEFAULT_COLUMN_FAMILY, cfOpts),
new ColumnFamilyDescriptor("my-first-columnfamily".getBytes(), cfOpts)
);
// a list which will hold the handles for the column families once the db is opened
final List<ColumnFamilyHandle> columnFamilyHandleList =
new ArrayList<>();
try (final DBOptions options = new DBOptions()
.setCreateIfMissing(true)
.setCreateMissingColumnFamilies(true);
final RocksDB db = RocksDB.open(options,
"path/to/do", cfDescriptors,
columnFamilyHandleList)) {
try {
// do something
} finally {
// NOTE user must explicitly frees the column family handles before freeing the db
for (final ColumnFamilyHandle columnFamilyHandle :
columnFamilyHandleList) {
columnFamilyHandle.close();
}
} // frees the column family options
}
} // frees the db and the db options
```
With the changes in this PR, the Java user no longer has to worry about manually closing the Column Families, which allows them to write simpler symmetrical create/free oriented code like this:
```java
try (final ColumnFamilyOptions cfOpts = new ColumnFamilyOptions().optimizeUniversalStyleCompaction()) {
// list of column family descriptors, first entry must always be default column family
final List<ColumnFamilyDescriptor> cfDescriptors = Arrays.asList(
new ColumnFamilyDescriptor(RocksDB.DEFAULT_COLUMN_FAMILY, cfOpts),
new ColumnFamilyDescriptor("my-first-columnfamily".getBytes(), cfOpts)
);
// a list which will hold the handles for the column families once the db is opened
final List<ColumnFamilyHandle> columnFamilyHandleList =
new ArrayList<>();
try (final DBOptions options = new DBOptions()
.setCreateIfMissing(true)
.setCreateMissingColumnFamilies(true);
final RocksDB db = RocksDB.open(options,
"path/to/do", cfDescriptors,
columnFamilyHandleList)) {
// do something
} // frees the column family options, then frees the db and the db options
}
}
```
**NOTE**: The changes in this PR are backwards API compatible, which means existing code using the original approach will also continue to function correctly.

Summary:
Allows adding event listeners in RocksJava.
* Adds listeners getter and setter in `Options` and `DBOptions` classes.
* Adds `EventListener` Java interface and base class for implementing custom event listener callbacks - `AbstractEventListener`, which has an underlying native callback class implementing C++ `EventListener` class.
* `AbstractEventListener` class has mechanism for selectively enabling its callback methods in order to prevent invoking Java method if it is not implemented. This decreases performance cost in case only subset of event listener callback methods is needed - the JNI code for remaining "no-op" callbacks is not executed.
* The code is covered by unit tests in `EventListenerTest.java`, there are also tests added for setting/getting listeners field in `OptionsTest.java` and `DBOptionsTest.java`.

Summary:
The PR fixes a Java test for Merge operator `uint64add`.
The current implementation uses wrong byte order for long serialization, but fails to catch this error because the merge sum is lower than `256`.
The PR makes this test case more representative (i.e. it fails with wrong byte order) and changes the byte order to little endian.
Some background: RocksDB uses LittleEndian byte order for integer serialization across all platforms. `MergeTest` uses `ByteBuffer` that defaults to BigEndian byte order.
This test case might probably be used as a sample of `MergeOperator` usage in Java.

Summary:
Adds compaction statistics (total bytes read and written) for compactions that occur for delete-triggered, periodic, and TTL compaction reasons.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/7165
Test Plan:
TTL and periodic can be checked by runnning db_bench with the options activated:
/db_bench --benchmarks="fillrandom,stats" --statistics --num=10000000 -base_background_compactions=16 -periodic_compaction_seconds=1
./db_bench --benchmarks="fillrandom,stats" --statistics --num=10000000 -base_background_compactions=16 -fifo_compaction_ttl=1
Setting the time to one second causes non-zero bytes read/written for those compaction reasons. Disabling them or setting them to times longer than the test run length causes the stats to return to zero as expected.
Delete-triggered compaction counting is tested in DBTablePropertiesTest.DeletionTriggeredCompactionMarking

This PR exposes the `Iterator::Refresh` method to the Java API by adding it on the `RocksIteratorInterface` interface. There are three concrete implementations: `RocksIterator`, `SstFileReaderIterator`, and `WBWIRocksIterator`. For the first two cases, the JNI side simply delegates to the underlying `Iterator::Refresh` method; in the last case, as it doesn't share an ancestor, and per the discussion in https://github.com/facebook/rocksdb/issues/3465, a `Status::NotSupported` exception is thrown.

Summary:
After we had a lot of failures with maven.org downloads, we
wanted an alternative location for downloading binary dependencies.
Hosting them through github would have been good in terms of
organizational and network dependencies, but that approach seems to be
awkward (fake releases, so would need a 'rocksdb-deps' repo) and
strangely complicated for Facebook policy on open source repositories.
This commit moves the downloads (that are not officially hosted by
others on github) from my personal rocksdb fork to an S3 bucket owned
by the Facebook RocksDB AWS account. Facebook employees can access
this through an internal tool, and we should be able to grant permission
to outside collaborators.
Assuming this works out, I will back-port to older branches to stabilize
their CI testing as well.

To ensure our RocksJava builds are working, we now instead install and use OpenJDK 8. Ideally we would use OpenJDK 7, as RocksJava supports Java 7, but many of the newer Travis containers don't support Java 7, so Java 8 is the next best thing.

Summary:
When paranoid_checks is on, DBImpl::CheckConsistency() iterates over all sst files and calls Env::GetFileSize() for each of them. As far as I could understand, this is pretty arbitrary and doesn't affect correctness - if filesystem doesn't corrupt fsynced files, the file sizes will always match; if it does, it may as well corrupt contents as well as sizes, and rocksdb doesn't check contents on open.
If there are thousands of sst files, getting all their sizes takes a while. If, on top of that, Env is overridden to use some remote storage instead of local filesystem, it can be *really* slow and overload the remote storage service. This PR adds an option to not do GetFileSize(); instead it does GetChildren() for parent directory to check that all the expected sst files are at least present, but doesn't check their sizes.
We can't just disable paranoid_checks instead because paranoid_checks do a few other important things: make the DB read-only on write errors, print error messages on read errors, etc.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6353

Summary:
This is a redesign of the API for RocksJava comparators with the aim of improving performance. It also simplifies the class hierarchy.
**NOTE**: This breaks backwards compatibility for existing 3rd party Comparators implemented in Java... so we need to consider carefully which release branches this goes into.
Previously when implementing a comparator in Java the developer had a choice of subclassing either `DirectComparator` or `Comparator` which would use direct and non-direct byte-buffers resepectively (via `DirectSlice` and `Slice`).
In this redesign there we have eliminated the overhead of using the Java Slice classes, and just use `ByteBuffer`s. The `ComparatorOptions` supplied when constructing a Comparator allow you to choose between direct and non-direct byte buffers by setting `useDirect`.
In addition, the `ComparatorOptions` now allow you to choose whether a ByteBuffer is reused over multiple comparator calls, by setting `maxReusedBufferSize > 0`. When buffers are reused, ComparatorOptions provides a choice of mutex type by setting `useAdaptiveMutex`.
---
[JMH benchmarks previously indicated](https://github.com/facebook/rocksdb/pull/6241#issue-356398306) that the difference between C++ and Java for implementing a comparator was ~7x slowdown in Java.
With these changes, when reusing buffers and guarding access to them via mutexes the slowdown is approximately the same. However, these changes offer a new facility to not reuse mutextes, which reduces the slowdown to ~5.5x in Java. We also offer a `thread_local` mechanism for reusing buffers, which reduces slowdown to ~5.2x in Java (closes https://github.com/facebook/rocksdb/pull/4425).
These changes also form a good base for further optimisation work such as further JNI lookup caching, and JNI critical.
---
These numbers were captured without jemalloc. With jemalloc, the performance improves for all tests, and the Java slowdown reduces to between 4.8x and 5.x.

Summary:
I set up a mirror of our Java deps on github so we can download
them through github URLs rather than maven.org, which is proving
terribly unreliable from Travis builds.
Also sanitized calls to curl, so they are easier to read and
appropriately fail on download failure.

Summary:
Both changes are related to RocksJava:
1. Allow dependencies that are already present on the host system due to Maven to be reused in Docker builds.
2. Extend the `make clean-not-downloaded` target to RocksJava, so that libraries needed as dependencies for the test suite are not deleted and re-downloaded unnecessarily.
