Summary: Ftruncate does not throw an error on disk-full. This causes Sig-bus in the case where the database tries to issue a Put call on a full-disk. Use posix_fallocate for allocation instead of truncate. Add a check to use MMaped files only on ext4, xfs and tempfs, as posix_fallocate is very slow on ext3 and older.

Summary: SizeBeingCompacted was called without any lock protection. This causes crashes, especially when running db_bench with value_size=128K.

This caused problems when run on jenkins. 3.8.1 has fixed this issue and we should use it from third party Also, have done away with log files. The whole output will be there on the terminal and the failed tests will be listed at the end.

Summary: The compaction process zeros out sequence numbers if the output is part of the bottommost level. The Slice is supposed to refer to an immutable data buffer. The merger that implements the priority queue while reading kvs as the input of a compaction run reies on this fact. The bug was that were updating the sequence number of a record in-place and that was causing suceeding invocations of the merger to return kvs in arbitrary order of sequence numbers. The fix is to copy the key to a local memory buffer before setting its seqno to 0. Test Plan: Set Options.purge_redundant_kvs_while_flush = false and then run db_stress --ops_per_thread=1000 --max_key=320 Reviewers: emayanke, sheki Reviewed By: emayanke CC: leveldb Differential Revision: https://reviews.facebook.net/D9147

Summary: This adds the rate_delay_limit_milliseconds option to make the delay configurable in MakeRoomForWrite when the max compaction score is too high. This delay is called the Ln slowdown. This change also counts the Ln slowdown per level to make it possible to see where the stalls occur. From IO-bound performance testing, the Level N stalls occur: * with compression -> at the largest uncompressed level. This makes sense because compaction for compressed levels is much slower. When Lx is uncompressed and Lx+1 is compressed then files pile up at Lx because the (Lx,Lx+1)->Lx+1 compaction process is the first to be slowed by compression. * without compression -> at level 1 Task ID: #1832108 Blame Rev: Test Plan: run with real data, added test Revert Plan: Database Impact: Memcache Impact: Other Notes: EImportant: - begin *PUBLIC* platform impact section - Bugzilla: # - end platform impact - Reviewers: dhruba Reviewed By: dhruba Differential Revision: https://reviews.facebook.net/D9045

Summary: Rocks accumulates recent writes and deletes in the in-memory memtable. When the memtable is full, it writes the contents on the memtable to a file in L0. This patch removes redundant records at the time of the flush. If there are multiple versions of the same key in the memtable, then only the most recent one is dumped into the output file. The purging of redundant records occur only if the most recent snapshot is earlier than the earliest record in the memtable. Should we switch on this feature by default or should we keep this feature turned off in the default settings?

Summary: Currently the test tracks all writes in memory and uses it for verification at the end. This has 4 problems: (a) It needs mutex for each write to ensure in-memory update and leveldb update are done atomically. This slows down the benchmark. (b) Verification phase at the end is time consuming as well (c) Does not test batch writes or snapshots (d) We cannot kill the test and restart multiple times in a loop because in-memory state will be lost. I am adding a FLAGS_multi that does MultiGet/MultiPut/MultiDelete instead of get/put/delete to get/put/delete a group of related keys with same values atomically. Every get retrieves the group of keys and checks that their values are same. This does not have the above problems but the downside is that it does less amount of validation than the other approach.

Summary: Changed the Get and Scan options with openForReadOnly mode to have access to the memtable. Changed the visibility of NewInternalIterator in db_impl from private to protected so that the derived class db_impl_read_only can call that in its NewIterator function for the scan case. The previous approach which changed the default for flush_on_destroy_ from false to true caused many problems in the unit tests due to empty sst files that it created. All unit tests pass now. Test Plan: make clean; make all check; ldb put and get and scans Reviewers: dhruba, heyongqiang, sheki Reviewed By: dhruba CC: kosievdmerwe, zshao, dilipj, kailiu Differential Revision: https://reviews.facebook.net/D8697

Summary: I missed InitTestDb() in one of my tess. InitTestDb() initializes the test directory, without which the test will throw IO error. This problem didn't occur before because I've already run the tests before so the test directory is already there. Test Plan: Reviewers: dhruba CC: Task ID: # Blame Rev:
