afa3518839 Revert "Update googletest from 1.8.1 to 1.10.0 (#6808)" (#6923)
Summary:
This reverts commit 8d87e9cea1.

Based on offline discussions, it's too early to upgrade to gtest 1.10, as it prevents some developers from using an older version of gtest to integrate to some other systems. Revert it for now.

0f85d163e6 Route GetTestDirectory to FileSystem in CompositeEnvWrappers (#6896)
Summary:
GetTestDirectory implies a file system operation (it creates the
default test directory if missing), so it should be routed to
the FileSystem rather than the Env.

Also remove the GetTestDirectory implementation in the PosixEnv,
since it overrides GetTestDirectory in CompositeEnv making it
impossible to override with a custom FileSystem.

172adce767 Posix threads (#6865)
Summary:
Rocksdb is using the c++11 std::threads feature. The issue is that
MINGW only supports it when using Posix threads.

This change will allow rocksdb::port::WindowsThread to be replaced
with std::thread, which in turn will allow Rocksdb to be cross
compiled using MINGW.

At the same time, we'll have to use GetCurrentProcessId instead of _getpid.

78e291b17e Improve consistency checks in VersionBuilder (#6901)
Summary:
The patch cleans up the code and improves the consistency checks around
adding/deleting table files in `VersionBuilder`. Namely, it makes the checks
stricter and improves them in the following ways:
1) A table file can now only be deleted from the LSM tree using the level it
resides on. Earlier, there was some unnecessary wiggle room for
trivially moved files (they could be deleted using a lower level number than
the actual one).
2) A table file cannot be added to the tree if it is already present in the tree
on any level (not just the target level). The earlier code only had an assertion
(which is a no-op in release builds) that the newly added file is not already
present on the target level.
3) The above consistency checks around state transitions are now mandatory,
as opposed to the earlier `CheckConsistencyForDeletes`, which was a no-op
in release mode unless `force_consistency_checks` was set to `true`. The rationale
here is that assuming that the initial state is consistent, a valid transition leads to a
next state that is also consistent; however, an *invalid* transition offers no such
guarantee. Hence it makes sense to validate the transitions unconditionally,
and save `force_consistency_checks` for the paranoid checks that re-validate
the entire state.
4) The new checks build on the mechanism introduced in https://github.com/facebook/rocksdb/pull/6862,
which enables us to efficiently look up the location (level and position within level)
of files in a `Version` by file number. This makes the consistency checks much more
efficient than the earlier `CheckConsistencyForDeletes`, which essentially
performed a linear search.

9360776cb9 Fix handling of too-small filter partition size (#6905)
Summary:
Because ARM and some other platforms have a larger cache line
size, they have a larger minimum filter size, which causes recently
added PartitionedMultiGet test in db_bloom_filter_test to fail on those
platforms. The code would actually end up using larger partitions,
because keys_per_partition_ would be 0 and never == number of keys
added.

The code now attempts to get as close as possible to the small target
size, while fully utilizing that filter size, if the target partition
size is smaller than the minimum filter size.

Also updated the test to break more uniformly across platforms

14eca6bf04 For ApproximateSizes, pro-rate table metadata size over data blocks (#6784)
Summary:
The implementation of GetApproximateSizes was inconsistent in
its treatment of the size of non-data blocks of SST files, sometimes
including and sometimes now. This was at its worst with large portion
of table file used by filters and querying a small range that crossed
a table boundary: the size estimate would include large filter size.

It's conceivable that someone might want only to know the size in terms
of data blocks, but I believe that's unlikely enough to ignore for now.
Similarly, there's no evidence the internal function AppoximateOffsetOf
is used for anything other than a one-sided ApproximateSize, so I intend
to refactor to remove redundancy in a follow-up commit.

So to fix this, GetApproximateSizes (and implementation details
ApproximateSize and ApproximateOffsetOf) now consistently include in
their returned sizes a portion of table file metadata (incl filters
and indexes) based on the size portion of the data blocks in range. In
other words, if a key range covers data blocks that are X% by size of all
the table's data blocks, returned approximate size is X% of the total
file size. It would technically be more accurate to attribute metadata
based on number of keys, but that's not computationally efficient with
data available and rarely a meaningful difference.

Also includes miscellaneous comment improvements / clarifications.

Also included is a new approximatesizerandom benchmark for db_bench.
No significant performance difference seen with this change, whether ~700 ops/sec with cache_index_and_filter_blocks and small cache or ~150k ops/sec without cache_index_and_filter_blocks.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6784

Test added to DBTest.ApproximateSizesFilesWithErrorMargin.

bcb9e41080 Explicitly free allocated buffer when status is not ok (#6903)
Summary:
Currently we rely on `BlockContents` to implicitly free the allocated scratch buffer, but when IO error happens, it doesn't make sense to construct the `BlockContents` which might be corrupted. In the stress test, we find that `assert(req.result.size() == block_size(handle));` fails because of potential IO errors.

In this PR, we explicitly free the scratch buffer on error without constructing `BlockContents`.

c5abf78bca avoid IterKey::UpdateInternalKey() in BlockIter (#6843)
Summary:
`IterKey::UpdateInternalKey()` is an error-prone API as it's
incompatible with `IterKey::TrimAppend()`, which is used for
decoding delta-encoded internal keys. This PR stops using it in
`BlockIter`. Instead, it assigns global seqno in a separate `IterKey`'s
buffer when needed. The logic for safely getting a Slice with global
seqno properly assigned is encapsulated in `GlobalSeqnoAppliedKey`.
`BinarySeek()` is also migrated to use this API (previously it ignored
global seqno entirely).

961c7590d6 Add timestamp to delete (#6253)
Summary:
Preliminary user-timestamp support for delete.

If ["a", ts=100] exists, you can delete it by calling `DB::Delete(write_options, key)` in which `write_options.timestamp` points to a `ts` higher than 100.

Implementation
A new ValueType, i.e. `kTypeDeletionWithTimestamp` is added for deletion marker with timestamp.
The reason for a separate `kTypeDeletionWithTimestamp`: RocksDB may drop tombstones (keys with kTypeDeletion) when compacting them to the bottom level. This is OK and useful if timestamp is disabled. When timestamp is enabled, should we still reuse `kTypeDeletion`, we may drop the tombstone with a more recent timestamp, causing deleted keys to re-appear.

Summary:
somehow the windows-server-2019-vs2019 image changed in a way that made
VS 14 2015 the default. This caused an error when we specify VS 16 2019

826295a5e9 Change autovector to have a reserved size in LITE mode (#6868)
Summary:
Previously in LITE mode, an autovector did not have a reserved size. When
elements were added to the vector, the underlying array could be reallocated.

There was a set of code that never expands the autovector and was doing &autovector::back().  When the vector is resized, the old addresses may become invalid, causing a later exception to be thrown.

By reserving space in the autovector up front, this problem is eliminated for those uses where the vector will never exceed the initial size.

the resize happens, these pointers become invalid, leading to SEGV or other exceptions.

This change allows the autovector to be fully populated before we take the address of any of its elements, thereby elminating the potential for a resize.

There is comparable code to this change in Version::MultiGet for dealing with the context objects.

1551f1011a Refactor the blob file related logic in VersionBuilder (#6835)
Summary:
This patch is groundwork for an upcoming change to store the set of
linked SSTs in `BlobFileMetaData`. With the current code, a new
`BlobFileMetaData` object is created each time a `VersionEdit` touches
a certain blob file. This is fine as long as these objects are lightweight
and cheap to create; however, with the addition of the linked SST set, it would
be very inefficient since the set would have to be copied over and over again.
Note that this is the same kind of problem that `VersionBuilder` is solving
w/r/t `Version`s and files, and we can apply the same solution; that is, we can
accumulate the changes in a different mutable object, and apply the delta in
one shot when the changes are committed. The patch does exactly that by
adding a new `BlobFileMetaDataDelta` class to `VersionBuilder`. In addition,
it turns the existing `GetBlobFileMetaData` helper into `IsBlobFileInVersion`
(which is fine since that's the only thing the method's clients care about now),
and adds a couple of helper methods that can create a `BlobFileMetaData`
object from the `BlobFileMetaData` in the base (if applicable) and the delta
when the `Version` is saved.

b9d65f5aa6 Trigger compaction in CompactOnDeletionCollector based on deletion ratio (#6806)
Summary:
In level compaction, if the total size (even if compensated after taking account of the deletions) of a level hasn't exceeded the limit, but there are lots of deletion entries in some SST files of the level, these files should also be good candidates for compaction. Otherwise, queries for the deleted keys might be slow because they need to go over all the tombstones.

This PR adds an option `deletion_ratio` to the factory of `CompactOnDeletionCollector` to configure it to trigger compaction when the ratio of tombstones >= `deletion_ratio`.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6806
