HP-Socket/MacOS

HP-Socket for MacOS

Project Introduction

Due to platform restrictions, some mechanisms may not be available properly.

Known mechanisms that cannot be provided normally:

1. Keep Live time in TCP protocol: TCP_KEEPALIVE, TCP_KEEPINTVL and TCP_KEEPCNT（Solution）。

2. Platform version (MacOS version) must be 10.12 or above (included).

The requirements for the platform version are mainly dependent on shared_timed_mutex in the component RWLock.h, and according to the definition of _LIBCPP_AVAILABILITY_SHARED_MUTEX, the platform version is required (if boost is used to replace this, it can also solve this problem).

HP-Socket for MacOS just provides the same callback interface as on other platforms, and internally uses some other mechanisms and components to replace corresponding incompatible components.

Mechanism

epoll => kqueue
ONESHOT=>DISPATCH

`DISPATCH` is equivalent to` edge-triggered (ET) `in epoll.` ONESHOT` will be deleted from the kernel in MacOS. 
For large data exchange, it means a large number of deletions and additions. 
Using ET (DISPATCH) will only Resetting the state (ENABLE) makes it invalid.

How to use the C interface?

Place the files in 4C directory into src directory and delete the following files

HPSocket.cpp
HPSocket.h
HPSocket-SSL.cpp
HPSocket-SSL.h

And provide an official http example test_server_4c using 4C interface

Full support for official usage examples
