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.

block_based_table_reader.cc is a giant file, which makes it hard for users to navigate the code. Divide the files to multiple files.
Some class templates cannot be moved to .cc file. They are moved to .h files. It is still better than including them all in block_based_table_reader.cc.

Summary:
This patch based on https://github.com/facebook/rocksdb/issues/5932 offers a better solution to add arm64 to TravisCI matrix.
Really thank adamretter for initiating Arm CI setup.
Difference comparing to amd64:
1. For CMake, as no official arm64 release ready on Kitware page,
a third party (conda-forge) released one is used instead of
building from source. The main reason is to save CI time.
2. Explicit export JAVA_HOME on arm64
3. Disable mingw test

Summary:
In the `.travis.yml` file the `jdk: openjdk7` element is ignored when `language: cpp`. So whatever version of the JDK that was installed in the Travis container was used - typically JDK 11.
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:
In Linux, when reopening DB with many SST files, profiling shows that 100% system cpu time spent for a couple of seconds for `GetLogicalBufferSize`. This slows down MyRocks' recovery time when site is down.
This PR introduces two new APIs:
1. `Env::RegisterDbPaths` and `Env::UnregisterDbPaths` lets `DB` tell the env when it starts or stops using its database directories . The `PosixFileSystem` takes this opportunity to set up a cache from database directories to the corresponding logical block sizes.
2. `LogicalBlockSizeCache` is defined only for OS_LINUX to cache the logical block sizes.
Other modifications:
1. rename `logical buffer size` to `logical block size` to be consistent with Linux terms.
2. declare `GetLogicalBlockSize` in `PosixHelper` to expose it to `PosixFileSystem`.
3. change the functions `IOError` and `IOStatus` in `env/io_posix.h` to have external linkage since they are used in other translation units too.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6457
Test Plan:
1. A new unit test is added for `LogicalBlockSizeCache` in `env/io_posix_test.cc`.
2. A new integration test is added for `DB` operations related to the cache in `db/db_logical_block_size_cache_test.cc`.

When users fail to open a DB with file lock failure, it is sometimes hard for users to debug. We now include the time the lock is acquired and the thread ID that acquired the lock, to help users debug problems like this. Default Env's thread ID is used.
Since type of lockedFiles is changed, rename it to follow naming convention too.

Summary:
It's never too soon to refactor something. The patch splits the recently
introduced (`VersionEdit` related) `BlobFileState` into two classes
`BlobFileAddition` and `BlobFileGarbage`. The idea is that once blob files
are closed, they are immutable, and the only thing that changes is the
amount of garbage in them. In the new design, `BlobFileAddition` contains
the immutable attributes (currently, the count and total size of all blobs, checksum
method, and checksum value), while `BlobFileGarbage` contains the mutable
GC-related information elements (count and total size of garbage blobs). This is a
better fit for the GC logic and is more consistent with how SST files are handled.

Allow user to specify options.max_open_files != -1 with FIFO compaction.
If max_open_files != -1, not all table files are kept open.
In the past, FIFO style compaction requires all table files to be open in order
to read file creation time from table properties. Later, we added file creation
time to MANIFEST, making it possible to read file creation time without opening
file.

On a file system which lacks of this feature, like zfs, it will fail to allocate predefined file size as this test case intends to do;

Summary:
In CompactRange, if there is no key in memtable falling in the specified range, then flush is skipped.
This PR extends this skipping logic to SST file levels: it starts compaction from the highest level (starting from L0) that has files with key falling in the specified range, instead of always starts from L0.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6482
Test Plan:
A new test ManualCompactionTest::SkipLevel is added.
Also updated a test related to statistics of index block cache hit in db_test2, the index cache hit is increased by 1 in this PR because when checking overlap for the key range in L0, OverlapWithLevelIterator will do a seek in the table cache iterator, which will read from the cached index.
Also updated db_compaction_test and db_test to use correct range for full compaction.

Test Plan: Run it and see it pass when liburing is enabled or not enabled.

Summary:
Today `WriteUnpreparedTxn::RollbackInternal` will write the rollback batch assuming that there is only a single subbatch. However, because untracked_keys_ are currently not deduplicated, it's possible for duplicate keys to exist, and thus split the batch. Also, tracked_keys_ also does not support compators outside of the bytewise comparators, so it's possible for duplicates to occur there as well.
To solve this, just pass in the correct subbatch count.
Also, removed `WriteUnpreparedRollbackPreReleaseCallback` to unify the Commit/Rollback codepaths some more.
Also, fixed a bug in `CommitInternal` where if 1. two_write_queue is true and 2. include_data is true, then `WriteUnpreparedCommitEntryPreReleaseCallback` ends up calling `AddCommitted` on the commit time write batch a second time on the second write. To fix, `WriteUnpreparedCommitEntryPreReleaseCallback` is re-initialized.

Summary:
Original author: jeffrey-xiao
If we are writing a global seqno for an ingested file, the range
tombstone metablock gets accessed and put into the cache during
ingestion preparation. At the time, the global seqno of the ingested
file has not yet been determined, so the cached block will not have a
global seqno. When the file is ingested and we read its range tombstone
metablock, it will be returned from the cache with no global seqno. In
that case, we use the actual seqnos stored in the range tombstones,
which are all zero, so the tombstones cover nothing.
This commit removes global_seqno_ variable from Block. When iterating
over a block, the global seqno for the block is determined by the
iterator instead of storing this mutable attribute in Block.
Additionally, this commit adds a regression test to check that keys are
deleted when ingesting a file with a global seqno and range deletion
tombstones.

Summary:
BlobDB currently does not keep track of blob files: no records are written to
the manifest when a blob file is added or removed, and upon opening a database,
the list of blob files is populated simply based on the contents of the blob directory.
This means that lost blob files cannot be detected at the moment. We plan to solve
this issue by making blob files a part of `Version`; as a first step, this patch makes
it possible to store information about blob files in `VersionEdit`. Currently, this information
includes blob file number, total number and size of all blobs, and total number and size
of garbage blobs. However, the format is extensible: new fields can be added in
both a forward compatible and a forward incompatible manner if needed (similarly
to `kNewFile4`).

Summary:
The logic that handles io_uring partial results was wrong. Fix the logic by putting it into a queue and continue reading.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6441
Test Plan: Make sure this patch fixes the application test case where the bug was discovered; in env_test, add a unit test that simulates partial results and make sure the results are still correct.
