Summary:
When `use_direct_reads` and `use_direct_writes` are `false`, `logical_sector_size_` inside various `*File` implementations are not actually used, so `GetLogicalBlockSize` does not necessarily need to be called for `logical_sector_size_`, just set a default page size.

When building RocksDB on VS2015, an error shows up with
hash_map.h(39): error C2719: 'value': formal parameter with requested alignment of 8 won't be aligned
Making the reference a reference can solve the problem, and there isn't a reason we can't do that, at least for the current use of the hash map.

Summary:
This commit fixes an incorrect version of this change that was previously landed.
On recently adding ARM64 and PPC64LE builds to Travis, we
seem to have hit some parallel build limits that dramatically increased
queue times.
This change majorly limits the configurations for ARM64 and PPC64LE to
build on each pull request, but keeps the large matrix for branch
builds.
In the process, I changed some previously excluded osx build configurations
to happen in branch builds.
NB: we might want to move master branch Travis build to daily trigger
rather than push trigger to further reduce contention.

Summary: TestPilot uses two flags to determine whether coverage is already instrumented: `fbcode_macros` and `coverage`. Normally, these two tags are added automatically to cpp tests, but this is a fake cpp test, so we must manually add them. The first is easy - `fbcode_macros` is added by the `custom_unittest` library, which is in `fbcode_macros`, so it is appropriate. The second is harder - we need to verify that we should add the macro. We do this using the `coverage.bzl` functions.

Summary:
Each time RocksDB switches to a new MANIFEST file from old one, it calls WriteCurrentStateToManifest() which writes a 'snapshot' of the current in-memory state of versions to the beginning of the new manifest as a bunch of version edits. We can distinguish these version edits from other version edits written during normal operations with a custom, safe-to-ignore tag.

object instead of using a raw `delete`.

Summary:
Currently, `db_stress` tests a randomly picked one of `GetLiveFiles`,
`GetSortedWalFiles`, and `GetCurrentWalFile` with a 1/N chance when the
command line parameter `get_live_files_and_wal_files_one_in` is specified.
The problem is that `GetSortedWalFiles` and `GetCurrentWalFile` are unreliable
in the sense that they can return errors if another thread removes a WAL file
while they are executing (which is a perfectly plausible and legitimate scenario).
The patch splits this command line parameter into three (one for each API),
and changes the crash test script so that only `GetLiveFiles` is tested during
our continuous crash test runs.

Summary:
https://github.com/facebook/rocksdb/pull/6531 removed some code in partitioned index seek logic. By mistake the logic of storing previous index offset is removed, while the logic of using it is preserved, so that the code might use wrong value to determine reseeking condition.
This will trigger a bug, if following a Seek() not going to the last block, SeekToLast() is called, and then Seek() is called which should position the cursor to the block before SeekToLast().

Summary:
Right now block based table iterator is used as both of iterating data for block based table, and for the index iterator for partitioend index. This was initially convenient for introducing a new iterator and block type for new index format, while reducing code change. However, these two usage doesn't go with each other very well. For example, Prev() is never called for partitioned index iterator, and some other complexity is maintained in block based iterators, which is not needed for index iterator but maintainers will always need to reason about it. Furthermore, the template usage is not following Google C++ Style which we are following, and makes a large chunk of code tangled together. This commit separate the two iterators. Right now, here is what it is done:
1. Copy the block based iterator code into partitioned index iterator, and de-template them.
2. Remove some code not needed for partitioned index. The upper bound check and tricks are removed. We never tested performance for those tricks when partitioned index is enabled in the first place. It's unlikelyl to generate performance regression, as creating new partitioned index block is much rarer than data blocks.
3. Separate out the prefetch logic to a helper class and both classes call them.
This commit will enable future follow-ups. One direction is that we might separate index iterator interface for data blocks and index blocks, as they are quite different.

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.

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

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`.

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.

Summary:
In direct IO mode, RandomAccessFileReader::Read allocates an internal aligned buffer, and then copies the result into the scratch buffer. If the result is only temporarily used inside a function, there is no need to do the memcpy and just let the result Slice refer to the internally allocated buffer.

Summary:
In most places in the code the variable names are spelled correctly as
COMMITTED but in a couple places not. This fixes them and ensures the
variable is always called COMMITTED everywhere.

Summary:
`TruncateLastLogAfterRecoverWithoutFlush` case depends on fallocate support
of underlying file system.
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;
So a check block is added to detect fallocate support and skip test if not.
The related work is done by JunHe77. Thanks!

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.

Summary:
In the current code base, we can use FaultInjectionTestEnv to simulate the env issue such as file write/read errors, which are used in most of the test. The PR https://github.com/facebook/rocksdb/issues/5761 introduce the File System as a new Env API. This PR implement the FaultInjectionTestFS, which can be used to simulate when File System has issues such as IO error. user can specify any IOStatus error as input, such that FS corresponding actions will return certain error to the caller.
A set of ErrorHandlerFSTests are introduced for testing
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6414
Test Plan: pass make asan_check, pass error_handler_fs_test.

Check for sys/auxv.h and getauxval before using them as they are not
always available (for example on uclibc)
