Windows/Boost LevelDB port updated to 1.18

[Edouard Alligand]

I'm pleased to announce that we've updated our custom LevelDB branch to 1.18.

This branch builds with CMake and uses the Boost Libraries. It also requires a C++ 11 compiler.

It fixes many issues that prevent LevelDB from working correctly in Windows.

Despite some improvements in the 1.18 branch, many signed/unsigned issues were left unresolved. We've done our best to improve the situation.

On a different topic, we're sorry to say that we've found a problematic function profile:

extern uint32_t Hash(const char* data, size_t n, uint32_t seed);

When working on bytes one should use unsigned types (unless you are looking for a very specific side effect).

On Windows the hash tests do not pass with a signed signature. We've corrected that in our branch and invite the the LevelDB authors to incorporate our fix.

Feedback warmly welcomed.

Our branch is available on GitHub:

Kind regards.

Hey there, you need to have the Boost Libraries installed.

Kind regards.
