* Add some std:: qualifiers to types and functions.Victor Costan2020-04-291-2/+2

* Add Env::Remove{File,Dir} which obsolete Env::Delete{File,Dir}.Victor Costan2020-01-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "DeleteFile" method name causes pain for Windows developers, because <windows.h> #defines a DeleteFile macro to DeleteFileW or DeleteFileA. Current code uses workarounds, like #undefining DeleteFile everywhere an Env is declared, implemented, or used. This CL removes the need for workarounds by renaming Env::DeleteFile to Env::RemoveFile. For consistency, Env::DeleteDir is also renamed to Env::RemoveDir. A few internal methods are also renamed for consistency. Software that supports Windows is expected to migrate any Env implementations and usage to Remove{File,Dir}, and never use the name Env::Delete{File,Dir} in its code. The renaming is done in a backwards-compatible way, at the risk of making it slightly more difficult to build a new correct Env implementation. The backwards compatibility is achieved using the following hacks: 1) Env::Remove{File,Dir} methods are added, with a default implementation that calls into Env::Delete{File,Dir}. This makes old Env implementations compatible with code that calls into the updated API. 2) The Env::Delete{File,Dir} methods are no longer pure virtuals. Instead, they gain a default implementation that calls into Env::Remove{File,Dir}. This makes updated Env implementations compatible with code that calls into the old API. The cost of this approach is that it's possible to write an Env without overriding either Rename{File,Dir} or Delete{File,Dir}, without getting a compiler warning. However, attempting to run the test suite will immediately fail with an infinite call stack ending in {Remove,Delete}{File,Dir}, making developers aware of the problem. PiperOrigin-RevId: 288710907

* Correct class/structure declaration order.Chris Mumford2019-05-031-3/+4
| | | | | | | | | | | | | 1. Correct the class/struct declaration order to be IAW the Google C++ style guide[1]. 2. For non-copyable classes, switched from non-implemented private methods to explicitly deleted[2] methods. 3. Minor const and member initialization fixes.

* Added native support for Windows.cmumford2019-03-011-0/+63
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
