Summary: In order to use arena to a use case that the total allocation size might be small (LogBuffer is already such a case), inline 1KB of data in it, so that it can be mostly in stack or inline in another class. If always inlining 2KB is a concern, I could make it a template to determine what to inline. However, dependents need to changes. Doesn't go with it for now Test Plan: make all check.

Summary: Original Summary: Yesterday, @ljin and I were debugging various db_stress issues. We suspected one of them happens when we concurrently call NewIterator without prefix_seek on HashSkipList. This test demonstrates it. Update: Arena is not thread-safe!! When creating a new full iterator, we *have* to create a new arena, otherwise we're doomed. Test Plan: SIGSEGV and assertion-throwing test now works! Reviewers: ljin, haobo, sdong Reviewed By: sdong CC: leveldb, ljin Differential Revision: https://reviews.facebook.net/D16857

Summary: This is is based on https://reviews.facebook.net/D15027. It's not finished but I would like to give a prototype to avoid arena over-allocation while making better use of the already allocated memory blocks. Instead of check approximate memtable size, we will take a deeper look at the arena, which incorporate essential idea that @sdong suggests: flush when arena has allocated its last and the last is "almost full" Test Plan: N/A Reviewers: haobo, sdong Reviewed By: sdong CC: leveldb, sdong Differential Revision: https://reviews.facebook.net/D15051

Summary: Add an option for arena block size, default value 4096 bytes. Arena will allocate blocks with such size. I am not sure about passing parameter to skiplist in the new virtualized framework, though I talked to Jim a bit. So add Jim as reviewer. Test Plan: new unit test, I am running db_test. For passing paramter from configured option to Arena, I tried tests like: TEST(DBTest, Arena_Option) { std::string dbname = test::TmpDir() + "/db_arena_option_test"; DestroyDB(dbname, Options()); DB* db = nullptr; Options opts; opts.create_if_missing = true; opts.arena_block_size = 1000000; // tested 99, 999999 Status s = DB::Open(opts, dbname, &db); db->Put(WriteOptions(), "a", "123"); } and printed some debug info. The results look good. Any suggestion for such a unit-test?

- Replace raw slice comparison with a call to user comparator. Added test for custom comparators. - Fix end of namespace comments. - Fixed bug in picking inputs for a level-0 compaction. When finding overlapping files, the covered range may expand as files are added to the input set. We now correctly expand the range when this happens instead of continuing to use the old range. For example, suppose L0 contains files with the following ranges: F1: a .. d F2: c .. g F3: f .. j and the initial compaction target is F3. We used to search for range f..j which yielded {F2,F3}. However we now expand the range as soon as another file is added. In this case, when F2 is added, we expand the range to c..j and restart the search. That picks up file F1 as well. This change fixes a bug related to deleted keys showing up incorrectly after a compaction as described in Issue 44. (Sync with upstream @25072954)
