Split Socket class into Tcp/Udp/DomainSocket subclasses.

Authored by ovyalov on Oct 14 2015, 3:59 PM.



There are a few reasons for this change:

  • Support generic logic flow for different socket types - a preparation step to support domain sockets in lldb-server along with TCP.
  • Offload Socket.cpp and make it more readable and serving more as a factory class.
  • Move out protocol-specific members like m_udp_send_sockaddr to more fine-grained classes.

Can we change "TcpSocket" to be "TCPSocket" and "UdpSocket" to be "UDPSocket" in all code and in the file names? Other than that it looks good.

Can you compile on Windows and make sure it works? Also should you add a unittest for Udp Sockets?

Looks good, with some random comments you can ignore.


I would rename these to something more neutral like name, addr, etc. as this will not be a host+port for the domain socket implementation.


Should we make this and Accept() abstract, as all implementations override it anyway?


This comment sounds obsolete. We should probably delete it.


Not really in scope of this patch, but I must say I find blindly deleting a file like this dangerous.

Good point - done.


If we're going to use unique file names per socket it shouldn't be too dangerous.

If we're going to use unique names, then this won't be necessary (and I would much rather see a random error opening a socket than a random file disappearing). BTW, have you considered using abstract sockets for the lldb-server use case? Albeit linux-specific, I find them much nicer, as they have no connection to the file system whatsoever.

I was thinking about using abstract sockets but didn't try them in runtime on Android - will check.
