OpenModelica.Scripting.system behaving different on Windows and Linux

[Andreas Heuermann]

The Modelica scripting function system surpresses output on Windows but not on Linux.

E.g calling the following mos-Script

system("echo \"Text output only on Linux visible\"");

only outputs the text on Linux.

I need it for testing OMSI FMUs with OMSimulator and check the error and warnings from OMSimulator. The test output should be equal on both OS.

I believe this is why we pipe the output to files in mos-scripts and then use readFile to print the log-file.

[Andreas Heuermann]

Okay, I made a workaround for my tests. Should it still be fixed in the future?

[Francesco Casella]

Releasing 1.14.0 which is stable and has many improvements w.r.t. 1.13.2. This issue is rescheduled to 1.16.0

[Francesco Casella]

Retargeted to 1.17.0 after 1.16.0 release

@sjoelund.se, should it be fixed?

[Andreas Heuermann]

Well there is an easy workaround for it.
But if we want all tests to pass on Windows without rewriting all that use system if would (maybe) be faster.

I see no point spending time to implement workarounds. Better fix the system function so that it behaves the same way on both OSs.

I suppose playing around with bInheritHandles and UpdateProcThreadAttributeList could work.

Retargeted to 1.18.0 because of 1.17.0 timed release.

Ticket retargeted after milestone closed
