Lecture #19 - Sockets-based Communication

Web Resources:

Content:

1. Syllabus
   Describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

2. Projects:

   Project #3, Project3HelpS17 Code Publisher Samples
   Code Publisher - publishing source code files as web pages.

   Project #4, Project4HelpS17
   Remote Code Publisher

3. Win32 Sockets

   Win32 Sockets Presentation, Windows Sockets Error Codes

   C++ Sockets, C++ StringServer
   This is the recommended source for sockets starter code.

   Message Passing Communication
   Discusses a proposed structure for message-passing communication for both Sockets and WCF.

   Tasks and ThreadPool
   Listeners for High load servers should use threadpool to run client handlers.

   HTTP style message-passing with File Transfer
   Demonstrates how to process HTTP style messages and send files. Has an HttpMessage class. Some of the server message handling could be better organized and made simpler.

   C++/CLI WPF application
   Illustrates how to build a GUI using C++/CLI. Uses a mock channel to show how to organize threading. This is important because managed code (C++/CLI and C#) must use .Net threads, but our channels all use C++11 threads. This demo shows how to do that.

   Beej's Guide to Network Programming (HTML pages), Beej's Guide to Network Programming (PDF document)
   Winsock Programmer's FAQ - out of date, but still useful

   Chalk Talk - File Transfer

   • Server structure - single queue
   • Sending file blocks

4. C++11 - new features

   Herb Sutter's excellent and brief overview from his Blog

   C++11 concurrency
   Threads, locks, condition variables, async, futures, promises, packaged_tasks, and atomics

   C++11 BlockingQueue
   Uses condition variable and mutex to build a queue that blocks deQers when empty.

   Str strings
   Demonstrates move constructor and move assignment.

   Component Reference Counting
   Demonstrates variadic templates and functions.

   Symbol Table
   Illustrates how using aliases are a great design tool. Also demonstrates range-based for loops.

   Chrono Timer
   Uses Chrono library to build a high resolution timer precise to about 100 nanoseconds.

   Callable Objects
   Demonstrates lambdas and compares them to function pointers and functors.

   Singleton
   Uses atomic.

   Uniform Initialization
   Illustrates use of uniform initialization for user defined types and STL containers.

5. Thinking about Software Design:

   Software Design
   Broad survey of ideas with examples
   Design Presentation
   Summarizes design issues for modules and classes.
   Design Guidelines
   Design rules and idioms that transcend Object Oriented Design.

   Design Summary
