>                 URL: https://issues.apache.org/jira/browse/MESOS-5932
>             Project: Mesos
>          Issue Type: Task
>            Reporter: Alex Clemmer
>            Priority: Major
>              Labels: agent, master, mesosphere, windows
> The replicated log (in src/log/) depends on leveldb to store and persist data 
> in the replicas.
> This dependency is well-contained within replica.cpp, but until it is 
> abstracted out, it nonetheless prevents the master from being built on 
> Windows, which in turn prevents the agent tests from being built and run on 
> Windows.
> Preliminary investigation shows that we will probably want to split this work 
> into 2 parts:
> * Temporarily remove the ability of the master to use the replicated log on 
> Windows (in master/main.cpp). This should involve 1 conditional where we 
> instantiate a `Log::Log`. This should be enough for us to light up the agent 
> tests.
> * Add leveldb Windows support to Mesos. This involves: adding CMake files to 
> build leveldb source, and adding Windows-specific `port_*` files that will 
> map the platform-specific constructs of leveldb to Windows. We can take hints 
> from leveldown and other projects, which add their own `port_*` files that 
> suit their purposes (namely, running leveldb, in node, on Windows). NOTE: the 
> leveldb community explicitly calls out in its documentation that it is not 
> interested in non-POSIX changes, so it is likely that this will never be 
> inducted into the mainline leveldb codebase.
