Dhruba Borthakur afed60938f Fox db_stress crash by copying keys before changing sequencenum to zero. ... 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		12 years ago
