I have posted a few messages concerning named pipes without any response so I guess people just don't use them. I have managed to figure out the issues so far and all turned out to be my mistake. Unfortunately I now have some issues reading (rather than writing which works fine now).
On the experiments I have done the following seems to be the case.
1. As Squeak is single threaded reading an empty pipe locks up Squeak. This was not unexpected and I need to be able to do a fcntl(stream, fcntl.F_SETFL, os.O_NDELAY). But I don't know how to do this in Squeak. I would also want to run this in a separate thread and AsyncFile looks useful for this.
2. FileStream atEnd always returns true regardless of how much data is in the pipe. This means everything that uses atEnd such as next: and things that use next: don't work either. In fact the only way to read data is to use next with no way to know when you are at the end of file.
3. FileStream size always returns a huge number that is always the same.
Any help with this would be much appreciated.
Thanks Bob
