由 Andres Noetzli 提交于
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. Then execute make db_test && ./db_test --gtest_filter=DBTest.ApproximateMemoryUsage Reviewers: rven, yhchiang, igor, sdong, anthony Reviewed By: anthony Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D45675

Summary: This patch adds the helper functions and variables to allow a backend implementing WritableFile to support direct IO when persisting a memtable. Test Plan: Since there is no upstream implementation of WritableFile supporting direct IO, the new behavior is disabled. Tests should be provided by the backend implementing WritableFile.

Summary: ReadaheadRandomAccessFile acts as a transparent layer on top of RandomAccessFile. When a Read() request is issued, it issues a much bigger request to the OS and caches the result. When a new request comes in and we already have the data cached, it doesn't have to issue any requests to the OS. We add ReadaheadRandomAccessFile layer only when file is read during compactions.

DBIter to out extra keys with higher sequence numbers when changing direction from forward to backward Summary: When DBIter changes iterating direction from forward to backward, it might see some much larger keys with higher sequence ID. With this commit, these rows will be actively filtered out. It should fix existing disabled tests in db_iter_test. This may not be a perfect fix, but it introduces least impact on existing codes, in order to be safe. Test Plan: Enable existing tests and make sure they pass. Add a new test DBIterWithMergeIterTest.InnerMergeIteratorDataRace8. Also run all existing tests.

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. Test Plan: Insert `usleep(10000);` just after `Reopen(options);` on line 2333 to make the issue more likely, then run: make db_test && while ./db_test --gtest_filter=DBTest.GetProperty; do true; done Reviewers: rven, yhchiang, anthony, igor, sdong Reviewed By: sdong Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D45603

Summary: As I keep adding new features to transactions, I keep creating more duplicate code. 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. Test Plan: No functionality change. existing tests pass.

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.

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.
