Messing with sockets
Locked
 
|
Hello,
I try to play with sockets in Pharo, and I encounter a strange error. Here is my code: |tempsock| Socket initialize. tempsock := Socket newTCP. tempsock listenOn: 12345 backlogSize: 4. [sock isNil] whileTrue:[sock:= tempsock waitForAcceptFor: 600]. sock sendCommand: 'Hello world!!'. sock ifNotNil: [[sock isConnected] whileTrue: [[sock waitForDataUntil:2000] ifTrue: [sock sendCommand:'Looping'. sock sendCommand: sock receiveData ]. ]]. sock closeAndDestroy. Once the connection is accepted, an exception is thrown in "sock waitForDataUntil:2000" by BlockCosure>>mustBeBooleanIn:context. From what I see, the signal "proceed for truth" is sent, and th debugger kicks in. How can I prevent the debugger from starting? Best regards, Geoffroy _______________________________________________ Pharo-users mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users |

Is it possible to have non-blocking read on sockets? I'm quite bad with network too :) But one day we will have to fix the examples and the code in network. > >>> sock ifNotNil: >>> [[sock isConnected] whileTrue: >>> [[sock waitForDataUntil:2000] ifTrue: >> >> (sock waitForDataUntil: 2000)? >> > > Thank you, it worked :) > > Best regards, > > Geoffroy > > _______________________________________________ > Pharo-users mailing list > [hidden email] > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users _______________________________________________ Pharo-users mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users |
