[iolib-devel] Introductory tcp client/server examples
by Peter Keller 14 May '10

14 May '10

Hello, I've been writing a tutorial for how to use IOLib loosely following the second edition of the unix network programming book by Richard Stevens. Attached to this mail is a tarball of a collection of example programs I've written which illustrate certain concepts in using IOLib. It is intended that this tutorial go all the way from the simple iterative daytime server example, all the way to nonblocking and multiplexed network i/o for a server with many clients. I am not finished with this work at all (such as the tutorial is simply an outline and I only have a small collection of example programs!), but Stelian wanted to see examples of the code I had written and thought the list would be a good place for it. Thank you. -pete

[iolib-devel] edge/level trigger in epoll backend
by Peter Keller 12 May '10

12 May '10

Hello, I'm seeing a problem in my codes where I have many clients using the multiplexer with nonblocking i/o all connected to a master process also using the multiplexer and nonblocking i/o and the master process only wants to serve one client for a very long time, then switch to another, and serve it a very long time. Meanwhile everyone is ready for work and should be marked as ready in the file descriptor set. This makes me wonder, is IOLib using EPOLLET to do edge triggered I/O in the linux backend? If so, I think that's not what most people will want since if data is left in the input/output buffers due to a short read/write, you'll never be notified of stuff left there. I want level triggered I/O to force pumping of the data regardless of what happens. Is there a means in IOLib I can control the edge/levelness of the backend? Thank you. -pete
