As a recent regression, mutex can be released while waiting for log sync. We move it to after file scanning. Test Plan: Run all existing tests. Don't think it is easy to write a unit test. Maybe we should find a way to assert lock not released so that we can have some test verification for similar cases.

| 2488020 | Andres Noetzli | 14 September 2015, 18:54:47 UTC | Relax asserts in arena_test Summary: Commit c67d2068988edccd0c732faec3d3c206089482c0 did not fix all test conditions which use Arena::MemoryAllocatedBytes() (see Travis failure https://travis-ci.org/facebook/rocksdb/jobs/79957700). The assumption of that commit was that aligned allocations do not call Arena::AllocateNewBlock(), so malloc_usable_block_size() would not be used for Arena::MemoryAllocatedBytes(). However, there is a code path where Arena::AllocateAligned() calls AllocateFallback() which in turn calls Arena::AllocateNewBlock(), so Arena::MemoryAllocatedBytes() may return a greater value than expected even for aligned requests.

This is probably due to malloc_usable_size() returning a value greater than the requested size. From the man page: The value returned by malloc_usable_size() may be greater than the requested size of the allocation because of alignment and minimum size constraints. Although the excess bytes can be overwritten by the application without ill effects, this is not good programming practice: the number of excess bytes in an allocation depends on the underlying implementation.

| 3c37b3c | Ari Ekmekji | 10 September 2015, 20:50:00 UTC | Determine boundaries of subcompactions Summary: Up to this point, the subcompactions that make up a compaction job have been divided based on the key range of the L1 files, and each subcompaction has handled the key range of only one file. However DBOption.max_subcompactions allows the user to designate how many subcompactions at most to perform. This patch updates the CompactionJob::GetSubcompactionBoundaries() to determine these divisions accordingly based on that option and other input/system factors. The current approach orders the starting and/or ending keys of certain compaction input files and then generates a histogram to approximate the size covered by the key range between each consecutive pair of keys. Then it groups these ranges into groups so that the sizes are approximately equal to one another. The approach has also been adapted to work for universal compaction as well instead of just for level-based compaction as it was before. These subcompactions are then executed in parallel by locally spawning threads, one for each. The results are then aggregated and the compaction completed.

| b42cd6b | Igor Canadi | 02 September 2015, 18:49:49 UTC | Remove the need for LATEST_BACKUP in BackupEngine Summary: In the first implementation of BackupEngine, LATEST_BACKUP was the commit point. The backup became committed after the write to LATEST_BACKUP completed. However, we can avoid the need for LATEST_BACKUP. Instead of write to LATEST_BACKUP, the commit point can be the rename from `meta/<backup_id>.tmp` to `meta/<backup_id>`. Once we see that there exists a file `meta/<backup_id>` (without tmp), we can assume that backup is valid. In this diff, we still write out the file LATEST_BACKUP. We need to do this so that we can maintain backward compatibility. However, the new version doesn't depend on this file anymore. We get the latest backup by `ls`-ing `meta` directory.

The interface documentation does not state that we need to return system time describing the return value as a number of microsecs since some moment in time. However, because on Linux it is implemented using gettimeofday various pieces of code (such as GenericRateLimiter) took advantage of that and make use of NowMicros() as a system timestamp. Thus the previous change broke rate_limiter_test on Windows. In addition, the interface name NowMicros() suggests that it is actually a timestamp so people use it as such. This change makes use of the new system call on Windows that returns system time with required precision. This change preserves the fix for auto_roll_logger_test and fixes rate_limiter_test. Note that DBTest.RateLimitingTest still fails due to a separately reported issue. | 02 September 2015, 18:12:07 UTC |

| 5508122 | Tomislav Novak | 31 August 2015, 23:44:34 UTC | Fix a perf regression in ForwardIterator Summary: I noticed that memtable iterator usually crosses the `iterate_upper_bound` threshold when tailing. Changes introduced in D43833 made `NeedToSeekImmutable` always return true in such case, even when `Seek()` only needs to rewind the memtable iterator. In a test I ran, this caused the "tailing efficiency" (ratio of calls to `Seek()` that only affect the memtable versus all seeks) to drop almost to zero. This diff attempts to fix the regression by using a different flag to indicate that `current_` is over the limit instead of resetting `valid_` in `UpdateCurrent()`.

| e853191 | Andres Noetzli | 27 August 2015, 23:17:08 UTC | Fix DBTest.ApproximateMemoryUsage Summary: This patch fixes two issues in DBTest.ApproximateMemoryUsage: - It was possible that a flush happened between getting the two properties in Phase 1, resulting in different numbers for the properties and failing the assertion. This is fixed by waiting for the flush to finish before getting the properties. - There was a similar issue in Phase 2 and additionally there was an issue that rocksdb.size-all-mem-tables was not monotonically increasing because it was possible that a flush happened just after getting the properties and then another flush just before getting the properties in the next round. In this situation, the reported memory usage decreased. This is fixed by forcing a flush before getting the properties. Note: during testing, I found that kFlushesPerRound does not seem very accurate. I added a TODO for this and it would be great to get some input on what to do there. Test Plan: The first issue can be made more likely to trigger by inserting a `usleep(10000);` between the calls to GetIntProperty() in Phase 1. The second issue can be made more likely to trigger by inserting a `if (r != 0) usleep(10000);` before the calls to GetIntProperty() and a `usleep(10000);` after the calls.

| 3795449 | Andres Noetzli | 26 August 2015, 17:10:26 UTC | Fix DBTest.GetProperty Summary: DBTest.GetProperty was failing occasionally (see task #8131266). The reason was that the test closed the database before the compaction was done. When the test reopened the database, RocksDB would schedule a compaction which in turn created table readers and lead the test to fail the assertion that rocksdb.estimate-table-readers-mem is 0. In most cases, GetIntProperty() of rocksdb.estimate-table-readers-mem happened before the compaction created the table readers, hiding the problem. This patch changes the WaitForFlushMemTable() to WaitForCompact(). WaitForFlushMemTable() is not necessary because it is already being called a couple of lines before without any insertions in-between.

This diff cleans this up by creating a base implementation class for Transaction and OptimisticTransaction to inherit from. The code in TransactionBase.h/.cc is all just copied from elsewhere. The only entertaining part of this class worth looking at is the virtual TryLock method which allows OptimisticTransactions and Transactions to share the same common code for Put/Get/etc. The rest of this diff is mostly red and easy on the eyes.

| 2050832 | Andres Noetzli | 25 August 2015, 00:04:18 UTC | Fixing race condition in DBTest.DynamicMemtableOptions Summary: This patch fixes a race condition in DBTEst.DynamicMemtableOptions. In rare cases, it was possible that the main thread would fill up both memtables before the flush job acquired its work. Then, the flush job was flushing both memtables together, producing only one L0 file while the test expected two. Now, the test waits for flushes to finish earlier, to make sure that the memtables are flushed in separate flush jobs. Test Plan: Insert "usleep(10000);" after "IOSTATS_SET_THREAD_POOL_ID(Env::Priority::HIGH);" in BGWorkFlush() to make the issue more likely.

| 4ab26c5 | Igor Canadi | 24 August 2015, 18:11:12 UTC | Smarter purging during flush Summary: Currently, we only purge duplicate keys and deletions during flush if `earliest_seqno_in_memtable <= newest_snapshot`. This means that the newest snapshot happened before we first created the memtable. This is almost never true for MyRocks and MongoRocks. This patch makes purging during flush able to understand snapshots. The main logic is copied from compaction_job.cc, although the logic over there is much more complicated and extensive. However, we should try to merge the common functionality at some point. I need this patch to implement no_overwrite_i_promise functionality for flush. We'll also need this to support SingleDelete() during Flush(). @yoshinorim requested the feature.
