Summary: For HashSkipList case, DBImpl has sanity check to see if prefix_extractor in options is the same as the one in memtable factory. If not, it falls back to SkipList. As result, I was experimenting with SkipList performance.

Summary: I wrote a test that triggers assertion in MergingIterator. I have not touched that code ever, so I'm looking for somebody with good understanding of the MergingIterator code to fix this. The solution is probably a one-liner. Let me know if you're willing to take a look.

Summary: The assert was pointless since if if prefix is the same as the whole key, assertion will surely fail. Reason behind is when performing the internal key comparison, if user keys are the same, *key with smaller transaction id* wins.

Summary: (1) Report corruption if backup meta file has tailing data that was not read. This should fix: https://github.com/facebook/rocksdb/issues/81 (also, @sdong reported similar issue) (2) Don't use OS buffer when copying file to backup directory. We don't need the file in cache since we won't be reading it twice (3) Don't delete newer backups when somebody tries to backup the diverged DB (restore from older backup, add new data, try to backup). Rather, just fail the new backup. Test Plan: backupable_db_test Reviewers: ljin, dhruba, sdong Reviewed By: ljin CC: leveldb, sdong Differential Revision: https://reviews.facebook.net/D16287

Summary: EncodeTo(&record) does not overwrite, it appends to it. This means that group commit log and apply will look something like: record1 record1record2 record1record2record3 I'm surprised this didn't show up in production, but I think the reason is that MANIFEST group commit almost never happens. This bug turned up in column family work, where opening a database failed with "adding a same column family twice".

Summary: This patch introduced a new table options that allows us to make block-based table's index pluggable. To support that new features: * Code has been refacotred to be more flexible and supports this option well. * More documentation is added for the existing obsecure functionalities. * Big surgeon on DataBlockReader(), where the logic was really convoluted. * Other small code cleanups. The pluggablility will mostly affect development of internal modules and won't change frequently, as a result I intentionally avoid heavy-weight patterns (like factory) and try to make it simple.

Summary: Previous code is too convoluted and I must be drunk for letting such code to be written without a second thought. Thanks to the discussion with @sdong, I added the `Options` when generating the flusher, thus avoiding the tricks. Just FYI: I resisted to add Options in flush_block_policy.h since I wanted to avoid cyclic dependencies: FlushBlockPolicy dpends on Options and Options also depends FlushBlockPolicy... While I appreciate my effort to prevent it, the old design turns out creating more troubles than it tried to avoid.

Summary: This diff does two things: (1) Log::Reader does not report a corruption when the last record in a log or manifest file is truncated (meaning that log writer died in the middle of the write). Inherited the code from LevelDB: https://code.google.com/p/leveldb/source/detail?r=269fc6ca9416129248db5ca57050cd5d39d177c8# (2) Turn off mmap writes for all writes to log and manifest files (2) is necessary because if we use mmap writes, the last record is not truncated, but is actually filled with zeros, making checksum fail. It is hard to recover from checksum failing. Test Plan: Added unit tests from LevelDB Actually recovered a "corrupted" MANIFEST file.

Any incoming Log request which log level is lower than Logger's log level will not be output. * The output of the newer version Log will be prefixed by its log level.

Summary: This will also help with avoiding the deadlock. If a flush failed and we're waiting for a memtable to be flushed, we should schedule a new flush and hope a new one succeedes. If paranoid_checks = false, Wait() will still hang on ENOSPC, but at least it will automatically continue when the space frees up. Current behavior both hangs and deadlocks. Also, I renamed some 'compaction' to 'flush'. 'compaction' was leveldb way of saying things.
