Added native support for Windows. This change adds a native Windows port (port_windows.h) and a Windows Env (WindowsEnv). Note1: "small" is defined when including <Windows.h> so some parameters were renamed to avoid conflict. Note2: leveldb::Env defines the method: "DeleteFile" which is also a constant defined when including <Windows.h>. The solution was to ensure this macro is defined in env.h which forces the function, when compiled, to be either DeleteFileA or DeleteFileW when building for MBCS or UNICODE respectively. This resolves #519 on GitHub. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=236364778 2019-03-02 05:12:01 +08:00			`#if defined(LEVELDB_PLATFORM_POSIX) \|\| defined(LEVELDB_PLATFORM_WINDOWS)`
Replace port_posix with port_stdcxx. The porting layer implements threading primitives: atomic pointers, condition variables, mutexes, thread-safe initialization. These are all specified in C++11, so the reference open source port implementation can become platform-independent. The porting layer will remain in place to allow the use of other implementations with more features, such as the built-in deadlock detection in abseil's Mutex. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=193245934 2018-04-18 04:23:10 +08:00			`# include "port/port_stdcxx.h"`
