[Gambas-user] Process' events stall after restart

[Tobias Boege]

Hi Benoit,

we noticed that the Read and Error events of a newly started Process don't
fire up when a former process was killed and the variable holding that
process gets filled with the new one which in turn shows the symptoms above.

To reproduce, open and start the attached project and

1. Start the process
2. Verify that it works by sending the sample command
3. Kill the process
4. Restart it
5. Send another command which yields nothing
6. Kill the process and see the output being flushed into the TextArea

This does not happen when step 3 reads "Start/Replace the process"
(consequently step 4 would be useless but the result is indifferent).

You will find a NOTE line in the source code. If one, before the new Process
gets started, assigns Null to the Process variable, everything seems to
work and output comes in instantly. Please tell me what is not supposed to
be done in a certain way there.

It was somewhat difficult to reproduce the issue in a smaller project than
the original one. I couldn't find any alternative to the 'bc' program. Hope
you can bear that dependency.

Regards,
Tobi
