Re: [Chicken-users] Fwd: Re: Active Windows users poll
I would vote for that too. Some eggs might be a little tricky to port though. I remember having troubles with a networking egg on cygwin.

I am very interested in this project since native Windows build is preferable when you work on Windows rather than mingw tricks. This will greatly shorten Chicken dependency list for Windows - one don`t need to install mingw stuff to build Chicken with eggs on Windows and use platform tools instead.

I'm working on new build system for Chicken, based on CMake which, besides more configurability and faster build times, can offer native Windows and MacOSX support with Visual Studio, XCode and other IDEs integration. I also can make installer with few eggs bundled and such. The system already allows seamless integration with CMake projects and tested on Linux. But doing full Windows port is more involved unfortunately. So, if anybody interested in native Windows port of Chicken, give your vote. ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users -- T: +1 (416) - 357.5356 Skype ID: pmelendezu ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] All threads are blocking by I/O
Hi guys, Sorry if the question is too basic but this is something that made me spent way more time that I expected. I am making a tcp server that attempts to be a dedicated game message server. I want to try a design that has a dedicated thread for the input of all input ports of all sockets and another thread for dedicated writing. I am deliberately trying to avoid having a thread for I/O on each socket connection. After some experimentation I came out to the realization that the reading thread is blocking all other threads. And I actually just found that stated on the TCP Unit documentation: - Blocking I/O will block all threads, except for some socket operations (see the section about the tcp unit). An exception is the read-eval-print loop on UNIX platforms: waiting for input will not block other threads, provided the current input port reads input from a console. So, I guess my question is if there is a way to workaround this or I have to combine my code with some C++ code to achieve what I want to do? I am aware of the mailbox-threads but it seems to me that they are actually are having a thread per connection which is what I was trying to avoid. Thanks in advance, Pedro. -- T: +1 (416) - 357.5356 Skype ID: pmelendezu ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
Re: [Chicken-users] All threads are blocking by I/O
Hi Peter! Thank you so much for your response! I don't understand then what I am doing wrong, this is what I have so far: https://github.com/pmelendez/scheme-test-server/blob/master/mini-tcp-server.scm Please notice that the code is dirty because it is a work in progress and I am kinda stuck. One detail I forgot to mention is that I am testing this on windows. Now after your explanation... Is it possible that the behavior is platform-specific? Thanks again for the help!

By default, the tcp unit's procedures will create nonblocking I/O ports, and the srfi-18 scheduler will multiplex threads over all open sockets using POSIX poll(). In other words, it should Just Work if you read in one thread and write in the other thread. Maybe I'm misunderstanding what you're trying to do? If so, could you please send us some sample code to avoid further confusion?

Re: [Chicken-users] All threads are blocking by I/O
Hey John, Yeah, I guess you are right... that's the easier solution at this point, it just sounded nicer to have it work without cygwin. Thanks!

[Chicken-users] Best way to share memory between C and Chicken
Hi all, Sorry if this question is obvious, but I couldn't find what I were looking for in the documentation so maybe you guys can help me. I am developing a prototype of a server that would serve 3D seismic images across the network. This task requires to process big files (~4 GB) with existing C code that is desirable to maintain. I plan to write the server itself in Chicken scheme but I would need to maintain the existing code in C that opens and process those files. Giving the size of the file, I want to share the memory space between C and Chicken and avoid copying values between areas. Is that even possible? Anyone has an idea on how can I address this?
