XOY-Leveldb

小组成员：谢瑞阳、徐翔宇

Hans Wennborg 213a68eb68 Sync with upstream @23860137 . Fix GCC -Wshadow warnings in LevelDB's public header files, reported by Dustin. Add in-memory Env implementation (helpers/memenv/). This enables users to create LevelDB databases in-memory. Initialize ShardedLRUCache::last_id_ to zero. This fixes a Valgrind warning. (Also delete port/sha1_ which were removed upstream some time ago.)			13 년 전

README

This directory contains interfaces and implementations that isolate the
rest of the package from platform details.

Code in the rest of the package includes "port.h" from this directory.
"port.h" in turn includes a platform specific "port_<platform>.h" file
that provides the platform specific implementation.

See port_posix.h for an example of what must be provided in a platform
specific header file.
