Lei Jin	0e526eb9d7	introduce TestMemEnv and use it in db_test ... Summary: TestMemEnv simulates all Env APIs using in-memory data structures. We can use it to speed up db_test run, which is now reduced ~7mins when it is enabled. We can also add features to simulate power/disk failures in the next step TestMemEnv is derived from helper/mem_env mem_env can not be used for rocksdb since some of its APIs do not give the same results as env_posix. And its file read/write is not thread safe Test Plan: make all -j32 ./db_test ./env_mem_test Reviewers: sdong, yhchiang, rven, igor Reviewed By: igor Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D28035	2014-10-31 15:08:10 -07:00
