Re: [Pharo-users] SocketStream persistence

by Daniel Klein

I just discoverd the 'noTimeout' message in the 'configuration' protocol, so that solves my persistence problem. But the question remains: When this process is running, it blocks until it completes. How can I fire it up so that I can continue to interact with Pharo while it is running?

SocketStream persistence

by Daniel Klein

For my first real Pharo task I need to communicate with a server over telnet. As a proof of concept I cobbled this code into a workspace without regard for OO-anything (the hostname/login/password have been changed to protect the innocent ;-) | wire answer | [ wire := SocketStream openConnectionToHostNamed: 'myhost' port: 23. [ wire upToAll: 'login: '. wire nextPutAll: 'testlogin'; cr; flush. wire upToAll: 'Password: '. wire nextPutAll: 'dummypassword'; cr; flush. wire upToAll: '>'. wire nextPutAll: 'dbl'; cr; flush. wire upToAll: '?'. wire nextPutAll: '12'; cr; flush. wire upTo: Character lf. answer := Integer readFromString: (wire upTo: (Character value: 3)). wire upToAll: 'C:\home>'. wire nextPutAll: 'exit'. "close gracefully" ] ensure: [wire close]. ^ answer ] on: ConnectionClosed do: [:ex | Transcript show: ex asString;cr. ex resume]. The server process, dbl, is a simple C program that takes a number, n, as input and returns n*2. I'm using character 3 to indicate the end of the output sent back from the C program. This all works great and I get the expected answer of '24'. So, the next step was to simulate the server process taking a while to complete and then send back some form of acknowledgement. So I put a 'sleep 5 minutes' in the server process just prior to sending back the answer. The problem is that I then get a 'ConnectionTimedOut' error after about 45-50 seconds. If I change the 'on:' line to: on: ConnectionClosed, ConnectionTimedOut then this errors out with 'IllegalResumeAttempt'. How can I keep the connection alive while the server is 'busy'? As an aside, while Pharo is processing the above code, I can't do anything else until it either completes or errors out. I thought Pharo used 'green threads'?

As I recall, I just downloaded the one-click .zip file, unzipped it, changed into whatever directory it was, then ran the pharo.sh script. I think I might have needed to `chmod u+x pharo.sh`, but I've been playing with a lot of different smalltalk versions lately, so that easily could have been one of the other dialects.
