Repository: mesos
Description
-------
This patch introduces the `int_fd` abstraction we use elsewhere to the
`LibeventSSLSocketImpl` for dealing with Linux versus Windows file
descriptors. This is necessary because on Windows, the consumer of
`LibeventSSLSocketImpl::create()` etc. already use `int_fd`.
Note that this does not break Linux systems, as `int_fd` is defined as
`int` on all non-Windows systems.
On Windows, however, in `evbuffer_add_file` we must explicitly convert
from `int_fd` (holding a Windows file handle) to a CRT `int` file
descriptor (the platform-specific call to `crt()`).
We have to correct the type expected by `evconnlistener_new` from `int`
to `evutil_socket_t`. This previously worked as just an `int` because
that is the underlying type used for sockets by libevent on Linux, but
it instead uses `intptr_t` on Windows. The `int_fd` abstraction can be
casted to `intptr_t` (and thus `evutil_socket_t`) automatically, but not
`int`, and so correcting the type to `evutil_socket_t` allows us to use
this lambda for the listener.
