Hi pharoers,

I am playing with OSProcess.

I am using an example, and I am annoyed with a strange bug:

Here is the code I want to execute, and does not work:

====

|thread process output|

myCmd := 'rostopic bw /turtle1/pose'.

thread := [process := (PipeableOSProcess command: myCmd) ] fork.

3 second wait.

output := process upToEnd.

output inspect.

thread terminate.

===

'rostopic bw /turtle1/pose' is a command that is a loop displaying the current bandwidth of a ROS process. In a terminal, it works fine. With OSProcess the output value is empty.

My source code is correct: if I replace myCmd by :

myCmd := 'ping localhost'.

It is a loop too, and it returns a correct string.

I have clearly no idea of where I have to search... Any help or discussion about that would be great :)

Thank you,

Oups, some infos:��

I am using Ubuntu 14.04

Pharo3.0 with Moose 5.0, latest update: #30863

The script I use (rostopic) is a python script (does it impact ?)
