What's the motivation behind adding this class?

[byungchul, 2014/06/04 17:41:28]

Devtools builds a socket factory class in UI thread, and instantiate a
server/listen socket in its own thread.
Devtools gets tcp server socket or unix domain server socket (for android).

[mmenke, 2014/06/04 21:00:00]

Hrm...Wonder if it makes more sense to make this DevTools class, then.  I'm not
strongly opposed to it here, just wondering if it really belongs in net/.

[byungchul, 2014/06/06 19:17:35]

Done.

+ public:
+  ServerSocketFactory();
+  virtual ~ServerSocketFactory();
+
+  // Returns a new instance of ServerSocket or NULL if an error occurred.
+  // It calls ServerSocket::Listen() with address and backlog set previously.
+  // Subclasses may override this function if ServerSocket::Listen() is not a
+  // right behavior.

[mmenke, 2014/06/04 16:29:50]

nit:  "a right behavior" -> "the right behavior"

[byungchul, 2014/06/06 19:17:35]

Done.

+  virtual scoped_ptr<ServerSocket> CreateAndListen() const;
+
+  void set_address(const IPEndPoint& address) { address_ = address; }

[mmenke, 2014/06/04 16:29:50]

It seems odd to me that this isn't an argument to CreateAndListen.

[byungchul, 2014/06/04 17:41:28]

Again, setting address and calling CreateAndListen() could happen in different
thread. For devtools, they are UI thread and devtools own thread respectively.

+  void set_backlog(int backlog) { backlog_ = backlog; }

[mmenke, 2014/06/04 16:29:50]

These should be documented.

[byungchul, 2014/06/06 19:17:35]

Removed and they are passed to constructor.
