Andrew Kryczka d1b26507bd fix db_compaction_test when compression disabled
Summary:
Previously, the compaction in `DBCompactionTestWithParam.ForceBottommostLevelCompaction` generated multiple files in no-compression use case, andone file in compression use case. I increased `target_file_size_base` so it generates one file in both use cases.

Yanqin Jin 1139422dfb Fix the command used to generate ctags
Summary:
In original $ROCKSDB_HOME/Makefile, the command used to generate ctags is
```
ctags * -R
```
However, this failed to generate tags for me.
I did some search on the usage of ctags command and found that it should be
```
ctags -R .
```
or
```
ctags -R *
```
After the change, I can find the tags in vim using `:ts <identifier>`.

Huachao Huang ecfca1ff59 Optimize overlap checking for external file ingestion
Summary:
If there are a lot of overlapped files in L0, creating a merging iterator for
all files in L0 to check overlap can be very slow because we need to read and
seek all files in L0. However, in that case, the ingested file is likely to
overlap with some files in L0, so if we check those files one by one, we can stop
once we encounter overlap.

Andrew Kryczka 0cdaa1a804 Fix WAL corruption from checkpoint/backup race condition
Summary:
`Writer::WriteBuffer` was always called at the beginning of checkpoint/backup. But that log writer has no internal synchronization, which meant the same buffer could be flushed twice in a race condition case, causing a WAL entry to be duplicated. Then subsequent WAL entries would be at unexpected offsets, causing the 32KB block boundaries to be overlapped and manifesting as a corruption.

This PR fixes the behavior to only use `WriteBuffer` (via `FlushWAL`) in checkpoint/backup when manual WAL flush is enabled. In that case, users are responsible for providing synchronization between WAL flushes. We can also consider removing the call entirely.

Summary:
I landed #3544 which made this test flaky. The reason was the files scheduled for deletion sometimes went through the trash-marking process, and sometimes were deleted directly. Our counter only bumped on the former code path, so if the latter code path was used, we'd miss counting a file deleted by deletion scheduler. This PR also bumps the counter in the latter code path.

Adam Retter c5302a8a58 Java wrapper for Native Comparators
Summary:
This is an abstraction for working with custom Comparators implemented in native C++ code from Java. Native code must directly extend `rocksdb::Comparator`. When the native code comparator is compiled into the RocksDB codebase, you can then create a Java Class, and JNI stub to wrap it.

Useful if the C++/JNI barrier overhead is too much for your applications comparator performance.

An example is provided in `java/rocksjni/native_comparator_wrapper_test.cc` and `java/src/main/java/org/rocksdb/NativeComparatorWrapperTest.java`.

amytai 0a3db28d98 Disallow compactions if there isn't enough free space
Summary:
This diff handles cases where compaction causes an ENOSPC error.
This does not handle corner cases where another background job is started while compaction is running, and the other background job triggers ENOSPC, although we do allow the user to provision for these background jobs with SstFileManager::SetCompactionBufferSize.
It also does not handle the case where compaction has finished and some other background job independently triggers ENOSPC.

Usage: Functionality is inside SstFileManager. In particular, users should set SstFileManager::SetMaxAllowedSpaceUsage, which is the reference highwatermark for determining whether to cancel compactions.

Summary:
This is the simplest way I could think of to speed up `CompactRange`. It works but isn't that optimal because it relies on the same `max_compaction_bytes` and `max_subcompactions` options that are used in other places. If it turns out to be useful we can allow overriding these in `CompactRangeOptions` in the future.

Fosco Marotto d518fe1da6 uint64_t and size_t changes to compile for iOS
Summary:
In attempting to build a static lib for use in iOS, I ran in to lots of type errors between uint64_t and size_t.  This PR contains the changes I made to get `TARGET_OS=IOS make static_lib` to succeed while also getting Xcode to build successfully with the resulting `librocksdb.a` library imported.

This also compiles for me on macOS and tests fine, but I'm really not sure if I made the correct decisions about where to `static_cast` and where to change types.

Also up for discussion: is iOS worth supporting?  Getting the static lib is just part one, we aren't providing any bridging headers or wrappers like the ObjectiveRocks project, it won't be a great experience.

  available.

  Adjust Windows Logger for the new interface, implement CloseImpl() Cc: anand1976

  Fix test running script issue where $status var was of incorrect scope
  so the failures were swallowed and not reported.

  DestroyDB() creates a logger and opens a LOG file in the directory
  being cleaned up. This holds a lock on the folder and the cleanup is
  prevented. This fails one of the checkpoin tests. We observe the same in production.
  We close the log file in this change.

Yi Wu b864bc9b5b Blob DB: Improve FIFO eviction
Summary:
Improving blob db FIFO eviction with the following changes,
* Change blob_dir_size to max_db_size. Take into account SST file size when computing DB size.
* FIFO now only take into account live sst files and live blob files. It is normal for disk usage to go over max_db_size because there are obsolete sst files and blob files pending deletion.
* FIFO eviction now also evict TTL blob files that's still open. It doesn't evict non-TTL blob files.
* If FIFO is triggered, it will pass an expiration and the current sequence number to compaction filter. Compaction filter will then filter inlined keys to evict those with an earlier expiration and smaller sequence number. So call LSM FIFO.
* Compaction filter also filter those blob indexes where corresponding blob file is gone.
* Add an event listener to listen compaction/flush event and update sst file size.
* Implement DB::Close() to make sure base db, as well as event listener and compaction filter, destruct before blob db.
* More blob db statistics around FIFO.
* Fix some locking issue when accessing a blob file.

Maysam Yabandeh 680864ae54 WritePrepared Txn: Fix bug with duplicate keys during recovery
Summary:
Fix the following bugs:
- During recovery a duplicate key was inserted twice into the write batch of the recovery transaction,
once when the memtable returns false (because it was duplicates) and once for the 2nd attempt. This would result into different SubBatch count measured when the recovered transactions is committing.
- If a cf is flushed during recovery the memtable is not available to assist in detecting the duplicate key. This could result into not advancing the sequence number when iterating over duplicate keys of a flushed cf and hence inserting the next key with the wrong sequence number.
- SubBacthCounter would reset the comparator to default comparator after the first duplicate key. The 2nd duplicate key hence would have gone through a wrong comparator and not being detected.

MergeOperatorPinningTest.Randomized/x tests are frequently failing with timeouts when run with tsan, as they are exceeding 10 minute limit for tests. The tests are in turn getting disabled due to frequent failures.
I halved the number of rounds to make the test complete sooner. This reduces the number of testing iterations a little, but it still is much better than totally letting the test be disabled.

Yi Wu 1209b6db5c Blob DB: remove existing garbage collection implementation
Summary:
Red diff to remove existing implementation of garbage collection. The current approach is reference counting kind of approach and require a lot of effort to get the size counter right on compaction and deletion. I'm going to go with a simple mark-sweep kind of approach and will send another PR for that.

CompactionEventListener was added solely for blob db and it adds complexity and overhead to compaction iterator. Removing it as well.

Maysam Yabandeh d060421c77 Fix a leak in prepared_section_completed_
Summary:
The zeroed entries were not removed from prepared_section_completed_ map. This patch adds a unit test to show the problem and fixes that by refactoring the code. The new code is more efficient since i) it uses two separate mutex to avoid contention between commit and prepare threads, ii) it uses a sorted vector for maintaining uniq log entires with prepare which avoids a very large heap with many duplicate entries.

Summary:
Add "rocksdb.live-sst-files-size" DB property which only include files of latest version. Existing "rocksdb.total-sst-files-size" include files from all versions and thus include files that's obsolete but not yet deleted. I'm going to use this new property to cap blob db sst + blob files size.

Andrew Kryczka 3ae0047278 skip CompactRange flush based on memtable contents
Summary:
CompactRange has a call to Flush because we guarantee that, at the time it's called, all existing keys in the range will be pushed through the user's compaction filter. However, previously the flush was done blindly, so it'd happen even if the memtable does not contain keys in the range specified by the user. This caused unnecessarily many L0 files to be created, leading to write stalls in some cases. This PR checks the memtable's contents, and decides to flush only if it overlaps with `CompactRange`'s range.

- Move the memtable overlap check logic from `ExternalSstFileIngestionJob` to `ColumnFamilyData::RangesOverlapWithMemtables`
- Reuse the above logic in `CompactRange` and skip flushing if no overlap
