Isn't it much more simpler here? It's just a one liner "if" check to check if
the reader is reader is not None and != for stale reader check. Here is the
code snipped I have used:
if (!reader.isSome() || reader.get() != oldReader) {

Sounds good to me. I suppose we don't use periods to terminate logging messages
?

How else would you communicate to the scheduler that it needs to subscribe
again in case of master disconnection/failover ? Feel free to re-open in case I
missed something

Why would you want to do that ? process::http::statuses[200] is a constant and
helps identify bugs like if (a = 5) by keeping the constant check on the left ?
Seems like I am missing something here

Not quite. I intend to add an constructor to Mesos::Mesos i.e. the wrapper
exposed class to the user later that would be used for testing. This is just
the internal implementation class.

Why ? This is anyways just the internal implementation class. Since we have to
do that for every request we make. Why not just save it as a constant member
variable ?

Fixed , my bad.

I wish we as a community can get adoption for clang format soon. These things
should be handled by a tool rather then someone spending time reviewing them :(
