Comment on Using boost::threadpool with boost::future by pachanga

pachanga — Thu, 10 Dec 2009 06:59:24 +0000

This should be very easy to achieve with a simple wrapper around the task. For example:

template<typename Task, typename Callback
struct TaskWithNotification
{
  TaskWithNotification(Task t, Callback c)
    : task(t),
      callback(c)
  {}
 
  void operator()()
  {
     callback(task());
  }
};

…and the usage is straightforward:

submit_job(
   threadpool, 
   TaskWithNotification(
     boost::bind(LoadUserTask, userId), 
     boost::bind(OnUserLoad, _1))
);

In C++0x completion handler can be a lambda.

Conception of Futures very popular on Java Platform also. But there is one thing that I’m missing in Futures - asynchronous completition. Sometimes there is no need to wait for task to complete. All I need is to give task and completition function to thread pool. For example:

Callable task = new LoadUserTask(userId);
executor.submit(task, new CompletionHandler {
  public void onComplete(User user) {
    user.setLastLoginTime(now());
  }
});

Is there something similar in C++?

Comment on A reliable way to serialize/unserialize objects in PHP by Autoload Magic | Straylight Run

Autoload Magic | Straylight Run — Thu, 07 May 2009 00:06:28 +0000

[…] Use a special container class that all other classes inherit from. This method is suitable mostly when attempting to unserialize objects (when unserializing objects, PHP must have the class definition to recover the object). This special container will automatically know the class file for the contained object. Then, the only class file that needs to be located is the container’s class file. (Autoloading in the context of object un/serialization is a special case of class loading.) […]

Comment on vim automatic upward search for make and scons build scripts by pachanga

pachanga — Thu, 03 Apr 2008 04:27:16 +0000

Yep, I’m currently a scons fan, however I’m also looking at CMake which is quite interesting for its ability to generate native build files(Makefile, KDevelop project, etc) for many platforms. This is really nice since end users won’t have to install CMake in order to build the application - standard tools(like make) should suffice.

Thanks for the post! This is a really handy vim function. So I take it you prefer scons then to make? I discovered scons about the same time you posted this last year. Won’t ever look back at make.
